TECHNICAL FIELD 
     The present disclosure relates to a kit for measuring the concentrations of an airborne bioaerosol and particulate matter. 
     BACKGROUND ART 
     In general, a method of measuring microbes floating in the air includes a method of measuring a bioaerosol. The method of measuring a bioaerosol includes forcibly inhaling a certain amount of the air, passing the air through a medium, and culturing microbes adsorbed onto the medium, and has an advantage in that it is possible to obtain results fairly close to the number of suspended microbes, but has drawbacks in that the results may vary according to the culture conditions or the measurement location and it takes a lot of time to obtain results. 
     Among a variety of conventional techniques for collecting microbes, Korean Patent No. 10-0549222 discloses the technique for collecting microbes in which the microbes in particles floating in the air are easily collected by inertial impaction by spraying the air onto a collection plate which rotates by means of a nozzle. However, the related art has drawbacks in that the microbes should be collected on the collection plate and transferred to culture equipment, and it is inconvenient to carry and move equipment due to an increase in volume thereof because a drive unit for rotating the collection plate, and the like are included.

     Hereinafter, a measurement kit  10  according to one embodiment of the present invention will be described in detail with reference to  FIGS. 1 to 12 . 
     Referring to  FIGS. 1 and 2 , the measurement kit  10  capable of measuring a concentration of an airborne bioaerosol and particulate matter according to one embodiment of the present includes a sampler  100 ,  100   a  or  100   b  configured to collect an airborne bioaerosol, an ATP measurement unit  500  configured to measure a concentration of the collected airborne bioaerosol, a particulate matter measurement unit  600  configured to measure a concentration of the particulate matter, and a control unit provided to receive first data output from the ATP measurement unit and second data output from the particulate matter measurement unit to generate third data. 
     The measurement kit  10  according to the present invention has advantages in that it is able to shorten a sampling time of germs (bacteria, and the like) and fungi (mold, and the like) having different size ranges, which float in the outside air, allow selective sampling, and rapidly output a relative proportion of bacterial and fungal particles per mass of particulate matter or per unit air volume by calculating concentration values measured through the ATP measurement unit  500  and the particulate matter measurement unit  600  by means of the control unit. 
     More specifically, referring to  FIGS. 3 and 4 , the sampler  100  according to the first embodiment of the present invention includes at least one swab  110  provided to attach the airborne bioaerosol thereto. 
     Also, the sampler  100  according to the first embodiment of the present invention includes a main body  120  having an internal space, wherein the swab  110  is detachably installed in the internal space, and having a first inlet port  121  and a first outlet port  122  provided, respectively, to allow outside air to be introduced and discharged therethrough. 
     The swab has a collection unit  111  to which the airborne bioaerosol is attached, and a fixing unit  113  extending from the collection unit  111  to fix the collection unit  111  in the internal space. 
     The main body  120  includes an upper holder  1201  having the first outlet port  122  provided therein, and a lower holder  1202  having the first inlet port  121  provided therein. 
     The upper holder  1201  and the lower holder  1202  are detachably connected so that a portion of an upper end of the lower holder  1202  is inserted into a lower end of the upper holder  1201 . Therefore, the upper holder  1201  and the lower holder  1202  may be detachably coupled to each other. 
     Here, because a sealing member  1207  (e.g., an O-ring) is provided at a portion of the upper end of the lower holder  1202 , a space between the upper holder  1201  and the lower holder  1202  may be sealed more tightly. 
     The first inlet port  121  may be provided at a roughly central region of the lower end  1202   b  of the lower holder  1202 , and the collection unit  111  of the swab may be disposed adjacent to the first inlet port  121 . 
     The fixing unit  113  of the swab is press-fitted into a portion of the upper holder  1201 , and thus the collection unit  111  may be fixed so that the collection unit  111  can be disposed adjacent to the first inlet port  121 . 
     The first outlet port  122  may be provided in a side portion of the upper holder  1201 , and the fixing unit  113  of the swab may be disposed between the first outlet port  122  and an upper end  1201   a  of the upper holder. 
     Also, a capping member  1205  may be provided at the upper end  1201   a  of the upper holder to cap an upper end of the upper end  1201   a.  One example of the capping member may be a set screw, but the present invention is not limited thereto. 
     Here, because each of an upper end  1202   a  of the lower holder  1202  and a lower end  1201   b  of the upper holder  1201  is open so that the upper holder  1201  is fluidically connected to the lower holder  1202 , the air flowing into the first inlet port  121  may flow toward the first outlet port  122 . 
     In addition, the sampler  100  according to the first embodiment of the present invention includes at least one separation unit  200  detachably installed on the first inlet port  121  side of the main body  120  and provided to supply the airborne bioaerosol, which falls within a predetermined selected size range, in the air introduced through the first inlet port  121 . 
     Referring to  FIGS. 5 and 6 , the separation unit  200  includes a first separation unit configured to supply the airborne bioaerosol having a size range of 2.5 μm or less in the air through the first inlet port  121  and a second separation unit configured to supply the airborne bioaerosol having a size range of 10 μm or less in the air through the first inlet port  121 , and at least one of the first and second separation units may be optionally installed. 
     Here, the airborne bioaerosol having a size range of 2.5 μm or less in the air may include airborne bacteria, and the airborne bioaerosol having a size range of 10 μm or less in the air may include airborne bacteria and airborne fungi. 
     Specifically, the airborne bioaerosol may be mainly divided into airborne bacteria having a size range of 2.5 μm or less and airborne fungi having a size range of more than 2.5 μm. 
     The airborne bacteria may include gram-negative bacteria and gram-positive bacteria. For example, the gram-negative bacteria may include  Escherichia Coli  having a size of approximately 0.91 μm, and the gram-positive bacteria may include  Staphylococcus epidermidis  having a size of approximately 0.78 μm, and the like, but the present invention is not limited thereto. 
     Also, the airborne fungi may, for example, include mold, and the like, but the present invention is not limited thereto. 
     As such, the separation unit  200  may include first and second separation units  200   a  and  200   b  separately provided to collect the airborne bioaerosols having different size ranges, respectively. 
     The separation unit  200  includes an inflow unit  210  through which the outside air containing the airborne bioaerosol is introduced, a nozzle unit  220  configured to increase a flow velocity of the air flowing into the inflow unit, and an impingement unit  230  configured to impinge the bioaerosol included in the air passing through the nozzle unit  220   
     The inflow unit  210  has a second inlet port  211  through which the air containing the airborne bioaerosol is introduced. 
     Also, the nozzle unit  220  is fluidically connected to the inflow unit  210 , and has at least one through hole  221  through which the introduced air flows. 
     The nozzle unit  220  has a cross-sectional area tapering from the inflow unit  210  toward the through hole  221 , and thus may increase the flow velocity of the introduced air when the air is passing through the through hole  221 . 
     Here, a plurality of through holes  221  may be provided. For example, three through holes  221  may be provided, but the present invention is not limited thereto. 
     The impingement unit  230  is fluidically connected to the nozzle unit  220 , and includes an impingement plate  231  provided to impinge some of the bioaerosol included in the air introduced through the nozzle unit  220 . 
     Here, the impingement plate  231  may be disposed to be spaced apart a predetermined distance from the through hole  221  of the nozzle unit. 
     The impingement unit  230  has an installation unit  233  installed on the first inlet port  121  side of the main body  120 , and a second outlet port  232  provided to allow the air introduced through the nozzle unit  220  to be introduced into the first inlet port  121  of the main body  120  may be provided on the installation unit  223  side (installation unit  233  side??). 
     The impingement unit  230  may be provided to have at least a portion of the cross-sectional area tapering from the impingement plate  231  side toward the installation unit  233  side. Therefore, because a flow velocity of the air introduced through the first inlet port  121  may increase, an amount of the bioaerosol attached to the swab may increase. 
     The installation unit  223  may be press-fitted to surround a portion of the lower end  1202   b  of the lower holder  1202  of the main body  120 . 
     Because a sealing member  1207  (e.g., an O-ring) is provided at a portion of the lower end of the lower holder  1202  to which the installation unit  223  is attached, a space between the separation unit  200  and the main body  120  may be sealed more tightly. 
     Referring to  FIG. 6 , the impingement plate  231  has an opening  231   a  provided to allow relatively small particles to flow to the second outlet port  232  with small inertia. 
     The outside air containing the bioaerosol is accelerated through the through hole  221  of the nozzle unit so that a jet streamline is formed by the impingement plate  231 . In this case, particles having a relatively large mass do not move along the jet streamline. Finally, only the particles having a size less than a certain size are allowed to pass through the opening  231   a  and are discharged through the second outlet port  232 . 
     The plurality of separation units  200  having a configuration as described above may be provided to collect the airborne bioaerosols having different size ranges, respectively, by adjusting a diameter d 1  of the through hole  221  of the nozzle unit and a distance d 2  between the through hole  221  and the impingement plate  231 . 
     For example, as the diameter d 1  of the through hole  221  of the nozzle unit and the distance d 2  between the through hole  221  and the impingement plate  231  become smaller, particles having a relatively smaller size may sequentially pass through the opening  231   a  and the first inlet port  121 , and may be attached to a swab. 
     That is, the diameter d 1  of the through hole  221  of the nozzle unit and the distance d 2  between the through hole  221  and the impingement plate  231  in the first separation unit may be provided to be smaller than the diameter d 1  of the through hole  221  of the nozzle unit and the distance d 2  between the through hole  221  and the impingement plate  231  in the second separation unit, respectively. 
     As described above, the first and second separation units have the same individual components, but may be provided to collect the airborne bioaerosols having different size ranges by adjusting the diameter d 1  of the through hole  221  of the nozzle unit  220  and the distance d 2  between the through hole  221  and the impingement plate  231 . 
     That is, in the case of the above-described separation unit  200 , the respective separation units (first and second separation units) formed by varying the diameter d 1  of the through hole  221  and the distance d 2  between the through hole  221  and the impingement plate  231  may be replaced and installed. Therefore, when collecting airborne bioaerosols having different size ranges, a plurality of swabs  110  may be replaced and installed to collect the airborne bioaerosol having different sizes. 
     For example, the first separation unit may be installed on the main body  120  to collect an airborne bioaerosol (for example, airborne bacteria) having a size range of 2.5 μm or less in the air using a swab (hereinafter referred to as a “first swab”), and the airborne bioaerosol may be separated from the first swab to measure an RLU value of the airborne bioaerosol using the ATP measurement unit  500  to be described below. Also, the second separation unit may be installed on the main body  120  to collect an airborne bioaerosol (for example, airborne bacteria and airborne fungi) having a size range of 10 μm or less in the air using a swab (hereinafter referred to as a “second swab”), and the airborne bioaerosol may be separated from the second swab to measure an RLU value of the airborne bioaerosol using the ATP measurement unit  500  to be described below. 
     That is, the ATP measurement unit  500  may measure RLU values of airborne bioaerosols including airborne bacteria and airborne bacteria and airborne fungi, respectively. 
     Meanwhile, the sampler  100  of the present invention includes an air flow device  300  configured to guide the flow of the air in order to attach the airborne bioaerosol onto the swab when the outside air containing the airborne bioaerosol is allowed to be introduced into an internal space of the main body  120 . 
     The air flow device  300  may be provided to form a pressure difference in order to allow the air to flow into the internal space of the main body  120 . For example, a pump, a fan, or the like may be used to force the flow of the outside air flowing into the internal space of the main body  120 . 
     The air flow device  300  may further include a flow rate control device  310  provided to adjust a flow rate of the introduced air under control of the air flow device  300 . 
     The air flow device  300  and the flow rate control device  310  may be electrically connected. 
     The air flow device  300  may be installed on the first outlet port  122  side of the main body to guide or force the outside air containing the airborne bioaerosol to flow toward the first outlet port  122  through the first inlet port  121  and the internal space in which the swab  110  is installed. 
     As such, the airborne bioaerosol introduced through the first inlet port  121  may be attached to the collection unit  111  of the swab. 
     In addition, the sampler  100  of the present invention may further include a humidification unit  400  provided to supply an aqueous solution containing a cell lysing agent toward the air flowing in the main body  120 . 
     The humidification unit  400  includes a humidification nozzle unit  410  configured to spray an aqueous solution including a cell lysing agent toward the air flowing into the main body  120 , and an aqueous solution supply unit (not shown) configured to supply the aqueous solution to the humidification nozzle unit  410 . 
     More specifically, the humidification unit  400  is fluidically connected to the separation unit  200 , and includes a humidification flow path  420  equipped with a third inlet port  421  through which the air containing the airborne bioaerosol is introduced. 
     Here, the aqueous solution supply unit provided to supply the aqueous solution to the humidification nozzle unit  410  may be configured separately as described above, and a space configured to accommodate the aqueous solution may be provided on the humidification nozzle unit  410 . That is, the aqueous solution supply unit and the humidification nozzle unit may be integrally formed. 
     Also, the humidification unit  400  may further include a controller  430  configured to control the operation of the humidification nozzle unit  410 , and the controller may control the operation of the humidification nozzle unit  410  using an On/Off switch. 
     In addition, the humidification nozzle unit  410  may be fluidically connected to at least a portion of the humidification flow path  420 . For example, the humidification nozzle unit  410  may be installed at the humidification flow path  420  side to spray the aqueous solution containing a cell lysing agent toward the separation unit  200  connected to the humidification flow path  420 . 
     Here, a configuration in which the humidification nozzle unit  410  is installed at the humidification flow path  420  has been described, but all types of configurations in which the humidification nozzle unit  410  may spray an aqueous solution containing a cell lysing agent toward the air supplied into the main body (toward the air supplied into the separation unit) are applicable. 
     The humidification nozzle unit  410  may atomize the cell lysing agent-containing aqueous solution along with humid air and supply the atomized aqueous solution to the separation unit  200  side. 
     For example, at least one selected from an NP-40 lysis buffer, a sodium dodecyl sulfate (SDS) lysis buffer, a bacterial cell lysis buffer (Gold Biotechnology Inc.), a Triton-based surfactant, and the like may be used as the cell lysing agent used in the cell lysing agent-containing aqueous solution. 
     Here, as the Triton-based surfactant, for example, Triton X-100 (Dow Chemical Inc.), which is a polyethylene P-T-octyl phenyl ether-based compound, may be used. More specifically, at least one selected from polyethylene glycol P-(1,1,3,3-tetramethylbutyl)-phenyl ether, octyl phenol ethoxylate, polyoxyethylene octyl phenyl ether, 4-octylphenol polyethoxylate, t-octylphenoxypolyethoxyethanol, and octoxynol-9 may be used in the present invention. 
     Because the humidification nozzle unit  410  is fluidically connected to the humidification flow path  420 , when the air flowing into the third inlet port  421  is allowed to flow toward the separation unit  200 , the humidification nozzle unit  410  may spray an aqueous solution toward the air flowing into the separation unit  200  so that both of the bioaerosol in the air and the cell lysing agent-containing aqueous solution can be allowed to flow into the separation unit  200 . 
     That is, the bioaerosol in the air flowing in the third inlet port  421  may be allowed to flow into the separation unit together with the cell lysing agent. 
     The cell lysing agent serves to lyse cell membranes of the airborne bioaerosol, and adenosine triphosphate (ATP) may be released from the airborne bioaerosol when the cell membranes are destroyed by the cell lysing agent. 
     Because such ATP reacts with a luminescent material as described below to emit light, the ATP is easily used to measure a concentration of the bioaerosol. That is, because the bioaerosol may be allowed to react with the cell lysing agent from the step of collecting the bioaerosol in the air in the humidification unit  400  according to the present invention, the time for extracting ATP from the bioaerosol may be shortened, thereby shortening the time for measuring the airborne bioaerosol. 
     Meanwhile, the measurement kit  10  of the present invention may further include the ATP measurement unit  500  configured to measure ATP in the airborne bioaerosol attached to the swab in order to measure a concentration of the airborne bioaerosol. 
     The ATP measurement unit  500  may be an RLU reader into which the collection unit  111  of the swab  110  is inserted to measure a relative luminescence unit (hereinafter referred to as “RLU”) of the bioaerosol attached to the swab. 
     In addition, the ATP measurement unit  500  may further include an ATP monitor  510  configured to output each of the measured ATP values as an RLU (RLU/m 3 ) value per unit air volume. 
     A method of optically measuring the bioaerosol may use a luminescent material and ATP released from the bioaerosol. The luminescent material includes luciferin and luciferase. 
     The luciferin is activated by ATP present in the lysed cells and converted into active luciferin, and the active luciferin is oxidized by an action of luciferase which is a luminescence enzyme and converted into oxyluciferin. In this case, chemical energy is converted into light energy to emit light. 
     Light emitted when the ATP extracted from the cells of the bioaerosol collected on the swab  110  reacts with the luminescent material may be measured using an RLU reader to calculate a concentration of the bioaerosol. In this case, ATP measurement unit  500  may further include a light source member (not shown) configured to irradiate light in order to facilitate measurement. 
     The measurement kit  10  including the ATP measurement unit  500  may shorten a measurement time because the measurement kit  10  may directly measure the bioaerosol collected on the swab  110 . 
     Here, the ATP measurement unit  500  may include the ATP monitor  510  provided to output each of the measured ATP values as an RLU value. 
     Meanwhile, the measurement kit  10  of the present invention includes the particulate matter measurement unit  600  provided to measure a concentration of the particulate matter falling within a predetermined size range, which is included in the air (outside air). 
     The particulate matter measurement unit  600  may be provided to measure each of fine particulate matter (a particulate matter size of 10 μm or less (PM 10)) and ultrafine particulate matter (a particulate matter size of 2.5 μm or less (PM 2.5) to output each of the measure values as a mass concentration value of the particulate matter per unit air volume (μg/m 3 ). 
     In addition, referring to  FIGS. 7 to 10 , the measurement kit  10  of the present invention may include a control unit provided to receive first data output from the ATP measurement unit  500  and second data output from the particulate matter measurement unit  600  to generate third data. 
     More specifically, the control unit may be provided to receive each of the first and second data to generate third data. In this case, because the control unit is electrically connected to each of the ATP measurement unit  500  and the particulate matter measurement unit  600  (is linked to transmit and receive the data), the control unit may be provided to receive the first and second data output from the respective measurement units to generate the third data converted through the control unit. 
     The control unit may further include a communication unit (not shown) provided to receive the first and second data output from the respective measurement units, and may generate third data based on the first and second data received from the communication unit. 
     The control unit may further include a user terminal capable of outputting a user interface, and may provide the generated third data to the user terminal. 
     Here, the communication unit may include short-range communication modules such as Wifi communication modules including a Bluetooth communication module, a Bluetooth low energy (BLE) communication module, a Zigbee communication module, a beacon communication module, and the like, an ultra-wideband (UWB) communication module, a LoRaWAN communication module, and the like, but the present invention is not limited thereto. 
     The user terminal may be provided to input user input values, and the user input values may, for example, include a volume flow rate of sampling air sampled using the sampler, a sampling time, a colony forming unit (CFU) conversion formula, a reference value for the airborne bioaerosol according to the measurement unit for each place, and reference values for fine particulate matter and ultrafine particulate matter for each place. 
     For example, the volume flow rate of the sampling air may refer to a volume (L/min) of the sampling air introduced per minute, the sampling time may refer to a sampling time in seconds (sec) required to collect the bioaerosol, the colony forming unit (CFU) conversion formula may refer to an correlation equation used to convert an RLU value into a CFU value, and the reference value may refers to a reference value for each of the airborne bioaerosols according to the concentration of the fine particulate matter or/and ultrafine particulate matter by place, which is judged by users. 
     As described above, the input user input values may be transmitted to the control unit. Therefore, the control unit may generate third data based on the first and second data measured respectively from the ATP measurement unit and the particulate matter measurement unit, and the user input values selected from the above-described user input values. 
     Also, the user terminal may include a display device configured to output the user interface for the third data provided by the control unit. 
     For example, the user terminal may be a terminal that enables wired and wireless network communication. For example, the user terminal may include a smart phone, a portable multimedia player (PMP), personal digital assistants (PDAs), a desktop PC, a laptop PC, a tablet PC, and the like, but the present invention is not limited thereto. 
     That is, the control unit may estimate the airborne bioaerosol and the particulate matter (fine particulate matter and ultrafine particulate matter) measurement result data based on the first data, the second data, and the user input values received through the user terminal and provide a user interface, which represents the estimated measurement result data in various formats, to the user terminal. Also, the control unit may be composed of a server, a storage unit (not shown) configured to store and manage the data, and the like, in addition to the above-described communication unit. 
     Here, the first data includes RLU (RLU/m 3 ) values of the airborne bioaerosol (for example, airborne bacteria) having a size of 2.5 μm or less and/or the airborne bioaerosol (for example, airborne bacteria and airborne fungi) having a size of 10 μm or less per unit air volume, and the second data includes mass concentration (μg/m 3 ) values of the fine particulate matter (having a particulate matter size of 10 μm or less (PM 10)) and/or the ultrafine particulate matter (having a particulate matter size of 2.5 μm or less (PM 2.5)) per unit air volume. 
     Also, the control unit may generate concentration values between a concentration of the fine particulate matter and a concentration of the ultrafine particulate matter, that is, a mass concentration value of the particulate matter having a particle size of greater than 2.5 μm and less than 10 μm, based on each of the concentration (PM10) of the fine particulate matter and the concentration (PM2.5) of the ultrafine particulate matter measured through the particulate matter measurement unit, and transmit the generated concentration values to the user terminal. 
     Here, the values between the concentration of the fine particulate matter and the concentration of the ultrafine particulate matter may refer to values (PM10-PM2.5) obtained by subtracting the concentration value of the ultrafine particulate matter from the concentration value of the fine particulate matter. 
     The third data may include at least one selected from an RLU value (RLU/μg [PM10]) of the airborne bioaerosol having a size range of 10 μm or less in the air per unit mass of the particulate matter calculated based on the first and second data or calculated based on the first data, the second data, and the user input values, an RLU value (RLU/μg [PM2.5]) of the airborne bioaerosol having a size range of 2.5 μm or less in the air per unit mass of the particulate matter, an RLU value (RLU/μg [PM10-PM2.5]) of the airborne bioaerosol having a size range of 2.5 μm to 10 μm in the air per unit mass of the particulate matter, a colony forming unit (CFU) value (CFU/μg [PM10]) of the airborne bioaerosol having a size range of 10 μm or less per unit mass of the particulate matter, a colony forming unit (CFU) value (CFU/μg [PM2.5]) of the airborne bioaerosol having a size range of 2.5 μm or less in the air per unit mass of the particulate matter, a colony forming unit (CFU) value (CFU/μg [PM10-PM2.5]) of the airborne bioaerosol having a size range of 2.5 μm to 10 μm in the air per unit mass of the particulate matter, a colony forming unit (CFU) value (CFU/m 3 [PM10]) of the airborne bioaerosol having a size range of 10 μm or less in the air per unit air volume, a colony forming unit (CFU) value (CFU/m 3 [PM2.5]) of the airborne bioaerosol having a size range of 2.5 μm or less in the air per unit air volume, a colony forming unit (CFU) value (CFU/m 3 [PM10-PM2.5]) of the airborne bioaerosol having a size range of 2.5 μm to 10 μm in the air per unit air volume, and a mass concentration value (μg/m 3 ) of the particulate matter having a particle size of greater than 2.5 μm and less than 10 μm per unit air volume. 
     Here, the third data is related to cases where the airborne bioaerosol (PM10) having a size range of 10 μm or less in the air includes both airborne bacteria and airborne fungi, the airborne bioaerosol (PM2.5) having a size range of 2.5 μm or less in the air include airborne bacteria (a size of the airborne bacteria is mainly less than or equal to 2 micrometers (μm)), and the airborne bioaerosol (PM10-PM2.5) having a size range of 2.5 μm to 10 μm in the air mainly includes airborne fungi. 
     Because the size of the airborne fungi is mainly greater than or equal to 3 μm, the airborne bioaerosol having a size range of 2.5 μm to 10 μm in the air may include some of the airborne bacteria, but mainly includes airborne fungi. 
     The colony forming unit (CFU) value may be deduced using the colony forming unit conversion formula. 
     The RLU and CFU have a linear relationship in the colony forming unit (CFU) conversion formula. 
     As described above, each of the plurality of pieces of third data generated from the measurement results based on the first data, the second data, and the user input values may be provided to the user terminal to easily determine the number of airborne fungi or/and airborne bacteria according to the concentrations of the fine particulate matter and ultrafine particulate matter at measurement places for each unit required by users without any separate comparison between the first data and the second data. 
     In particular, the user interface may include a user input window  1000  configured to input at least one selected from a volume flow rate of the sampling air, a sampling time, a colony forming unit (CFU) conversion formula, a reference value for the airborne bioaerosol per mass or volume of the fine particulate matter, and a reference value for the airborne bioaerosol per mass or volume of the ultrafine particulate matter; a data input window (not shown) configured to transmit the first and second data to the control unit; a third data output window  2000  configured to provide a numerical value of the airborne bioaerosol according to the location of the measurement result data, and the concentrations of the fine particulate matter and ultrafine particulate matter, and a third data schematization output window  3000  configured to provide each piece of the third data in a schematized form. 
     The user input window  1000  includes a sampling air volume flow rate input window  1001 , a sampling time input window  1002 , a colony forming unit (CFU) conversion formula input window  1003 , and a reference value input window  1004  configured to input a reference value for the airborne bioaerosol per mass or volume of the fine particulate matter and a reference value for the airborne bioaerosol per mass or volume of the ultrafine particulate matter. In this case, each of the numerical values may be input into the user interface output through the user terminal, and the numerical values in the input window may be optionally input according to the users&#39; purpose of analysis. 
     Here, each of the reference values input through the reference value input window  1004  may be, for example, each of reference values for mass concentrations and/or CFU values of the airborne bioaerosol (10 μm or less, 2.5 μm or less, and 2.5 μm to 10 μm) per unit air volume at a certain place, and each of reference values for RLU values and/or CFU values per unit mass of the airborne bioaerosol. 
     In particular, when a user input window which is not required to estimate the measurement result data is present depending on the users, a user may manipulate a management option (not shown) of the user input window to display only the necessary user input windows on the user interface. 
     For example, when a user is required to check the RLU values rather than the CFU values, the user may not input a separate numerical value into the colony forming unit (CFU) conversion formula input window, or may manipulate the management option of the user input window so as not to display the colony forming unit (CFU) conversion formula input window on the user interface. 
     In addition, the third data output window  2000  includes each of measurement place output windows  2001  and RLU numerical value output windows  2002  for the airborne bioaerosol having a size of 10 μm or less and the airborne bioaerosol having a size of 2.5 μm or less for each place. 
     For example, the RLU numerical value output window  2002  for the airborne bioaerosol for each place may output the RLU numerical value for the airborne bacteria and airborne fungi and the RLU numerical value for the airborne bacteria. 
     As described above, when each of the numerical values is input through the user input window  1000  according to the purpose of analysis, and the first and second data measured through each of the measurement units  500  and  600  are received by the control unit, as shown in  FIG. 8 , the places at which the bioaerosol (airborne fungi and airborne bacteria, or airborne germs) are measured may be displayed on the measurement place output window  2001 , and each of the RLU numerical values and/or CFU numerical values measured for each of the places may be displayed on the RLU numerical value output window  2002 . 
     In addition, the third data schematization output window  3000  may schematize and output the plurality of pieces of third data in the form of a bar graph, a broken line graph, a radar graph, a pie graph, or the like in order to provide the user&#39;s intuitive analysis of the plurality of pieces of third data, and may output numerical values regarding each of the reference values input through the reference value input window  1004  together with the schematized data. 
     Here, the third data schematization output window  3000  includes an ATP output window  3001  configured to output each of the RLU numerical values of the airborne bioaerosol per unit air volume by measurement place in the above-described schematized form for the first data on the user interface, and a PM output window  3002  configured to output the mass concentration values of the fine particulate matter (PM10) and ultrafine particulate matter (PM2.5) per unit air volume by measurement place in the above-described schematized form for the second data on the user interface. 
     For example, referring to  FIG. 9 , the ATP output window  3001  may output the RLU numerical values of the airborne bioaerosol (including airborne fungi and airborne bacteria) having a size range of 10 μm or less per unit air volume by measurement place and the airborne bioaerosol (including airborne bacteria) having a size range of 2.5 μm or less in the air for the first data in the form of respective bar graphs on the user interface, the PM output window  3002  may output the mass concentration values of the fine particulate matter (PM10) and ultrafine particulate matter (PM2.5) per unit air volume by measurement place for the second data in the form of respective bar graphs. 
     Here, a reference line v representing each of the reference values for the airborne bioaerosol and/or the reference values for the fine particulate matter and ultrafine particulate matter according to the size range by measurement place may be displayed in the form of a horizontal straight line on each of the output windows. 
     The reference line v includes a PM10 reference line v 1  representing a reference value for fine particulate matter, and a PM2.5 reference line v 2  representing a reference value for ultrafine particulate matter. Also, each of a first reference line v 3  representing a reference value for the airborne bioaerosol (including airborne fungi and airborne bacteria) having a size range of 10 μm or less according to each of the units, a second reference line v 4  representing a reference value for the airborne bioaerosol (including airborne bacteria) having a size range of 2.5 μm or less in the air, and a third reference line (not shown) representing a reference value for the airborne bioaerosol (mainly including airborne fungi) having a size range of 2.5 μm to 10 μm in air may be displayed in the form of a horizontal straight line. 
     Also, the third data schematization output window  3000  includes a first output window  3003  configured to output the RLU numerical values of the airborne bioaerosol (including airborne fungi and airborne bacteria) having a size range of 10 μm or less per mass of the unit particulate matter (fine particulate matter and ultrafine particulate matter) by place for the third data, the airborne bioaerosol (including airborne bacteria) having a size range of 2.5 μm or less in the air, and the airborne bioaerosol (mainly including airborne fungi) having a size range of 2.5 μm to 10 μm in the air in the above-described schematized form on the user interface. 
     Also, the third data schematization output window  3000  includes a second output window  3004  configured to output the CFU numerical values of the airborne bioaerosol (including airborne fungi and airborne bacteria) having a size range of 10 μm or less per air volume of the unit particulate matter (fine particulate matter and ultrafine particulate matter) by place, the airborne bioaerosol (including airborne bacteria) having a size range of 2.5 μm or less in the air, and the airborne bioaerosol (mainly including airborne fungi) having a size range of 2.5 μm to 10 μm in the air in the above-described schematized form. 
     Furthermore, the third data schematization output window  3000  includes a third output window  3005  configured to output the CFU numerical values of the airborne bioaerosol (including airborne fungi and airborne bacteria) having a size range of 10 μm or less per mass of the unit particulate matter (fine particulate matter and ultrafine particulate matter) by place, the airborne bioaerosol (including airborne bacteria) having a size range of 2.5 μm or less in the air, and the airborne bioaerosol (mainly including airborne fungi) having a size range of 2.5 μm to 10 μm in the air in the above-described schematized form. 
     In particular, the third data schematization output window  3000  may further include a fourth output window (not shown) configured to output a mass concentration value of the particulate matter having a particle size range between the fine particulate matter (PM10) and the ultrafine particulate matter (PM2.5) per unit air volume by measurement place in the form of a bar graph. 
     That is, the fourth output window may output each of the mass concentration values (μg/m 3 ) of the particulate matter having a particle size of greater than 2.5 μm and less than 10 μm per unit air volume by place in the above-described schematized form. 
     For example, referring to  FIG. 10 , the first output window  3003  may output each of the RLU numerical values of the airborne bioaerosol (including airborne fungi and airborne bacteria) having a size range of 10 μm or less per mass of the unit particulate matter (fine particulate matter and ultrafine particulate matter) by place, the airborne bioaerosol (including airborne bacteria) having a size range of 2.5 μm or less in the air, and the airborne bioaerosol (mainly including airborne fungi) having a size range of 2.5 μm to 10 μm in the air in the form of a bar graph. 
     Here, the RLU numerical value of the airborne bioaerosol (mainly including airborne fungi) having a size range of 2.5 μm to 10 μm in the air may refer to a value obtained by subtracting a measured value of the airborne bioaerosol having a size range of 2.5 μm or less from a measured value of the airborne bioaerosol having a size range of 10 μm or less. 
     Also, the second output window  3004  may output each of the CFU numerical values of the airborne bioaerosol (including airborne fungi and airborne bacteria) having a size range of 10 μm or less per air volume of the unit particulate matter (fine particulate matter and ultrafine particulate matter) by place, the airborne bioaerosol (including airborne bacteria) having a size range of 2.5 μm or less in the air, and the airborne bioaerosol (mainly including airborne fungi) having a size range of 2.5 μm to 10 μm in the air in the form of a bar graph, and the third output window  3005  may output each of the CFU numerical values of the airborne bioaerosol (including airborne fungi and airborne bacteria) having a size range of 10 μm or less per mass of the unit particulate matter (fine particulate matter and ultrafine particulate matter) by place, the airborne bioaerosol (including airborne bacteria) having a size range of 2.5 μm or less in the air, and the airborne bioaerosol (mainly including airborne fungi) having a size range of 2.5 μm to 10 μm in the air in the form of a bar graph. 
     Here, the first reference line v 1 , the second reference line v 2 , and the third reference line (not shown) representing a reference value for the airborne bioaerosol (including airborne fungi and airborne bacteria) having a size range of 10 μm or less according to each of the units, a reference value for the airborne bioaerosol (including airborne bacteria) having a size range of 2.5 μm or less in the air, and a reference value for the airborne bioaerosol (mainly including airborne fungi) having a size range of 2.5 μm to 10 μm in the air, respectively, may be displayed in the form of a horizontal straight line on each of the output windows. 
     Therefore, because each of the pieces of data on the concentration of the fine particulate matter and ultrafine particulate matter, the concentration of the airborne bacteria and airborne fungi, the concentration of the airborne bacteria, and the concentration of the airborne fungi for each place may be directly compared with the reference value, a relative proportion of the bacterial and fungal particles may be more easily and rapidly determined. 
     Meanwhile, referring to  FIG. 11 , a sampler  100   a  according to a second embodiment of the present invention includes at least one swab  110 , a main body  120 , a first separation unit  200   a,  a second separation unit  200   b,  first and second flow paths  251  and  252 , a valve  253 , and an air flow device  300 . 
     Hereinafter, a description of the same components as those of the sampler  100  according to the first embodiment as described above will be omitted. 
     In the sampler  100  according to the first embodiment of the present invention, both of the swab  110  and the separation unit  200  are replaced and installed to separate and collect airborne bioaerosols having different size ranges. However, in the sampler  100   a  according to the second embodiment, because each of the first and second separation units  200   a  and  200   b  is connected to one main body  120  unlike the first embodiment, only the swab  110  may be replaced to separate and collect the airborne bioaerosols having different size ranges. 
     More particularly, the sampler  100   a  according to the second embodiment includes first and second flow paths  251  and  252  fluidically connected to the first inlet port  121  of the main body  120 , respectively. 
     Also, the first separation unit  200   a  is installed on the first flow path  251  side, and may be provided to supply the airborne bioaerosol falling within a first size range in the air introduced through the first inlet port  121 . 
     Also, the second separation unit  200   b  is installed on the second flow path  252  side, and may be provided to supply the airborne bioaerosol falling within a second size range in the air introduced through the first inlet port  121 . 
     Here, the airborne bioaerosol falling within the first size range may have a size range of 2.5 μm or less in the air, and the airborne bioaerosol falling within the second size range may have a size range of 10 μm or less in the air. 
     In addition, the valve  253  may be provided on the first inlet port  121  side to fluidically connect the first inlet port  121  to the first flow path  251 , or may be provided to fluidically connect the first inlet port  121  to the second flow path  252 . 
     For example, the valve  253  may be controlled so that the first inlet port  121  can be fluidically connected to the first flow path  251 . In this case, when the airborne bioaerosol falling within the first size range is attached to the swab  110  and collected, the swab to which the airborne bioaerosol falling within the first size range is attached is detached from the main body. Then, another swab is installed, and the valve  253  is controlled again to fluidically connect the first inlet port  121  to the second flow path  252 . In this case, the airborne bioaerosol falling within the second size range may be attached to another swab to collect the airborne bioaerosol. 
     Here, the valve  253  may be, for example, a three-way valve, but the present invention is not limited thereto. 
     Also, the air flow device may force the flow of the outside air into the main body. 
     Meanwhile, referring to  FIG. 12 , a sampler  100   b  according to a third embodiment of the present invention includes first and second swabs  110   a  and  110   b,  first and second main bodies  120   a  and  120   b,  first and second separation units  200   a  and  200   b,  and an air flow device  300 . 
     Hereinafter, a description of the same components as those of the samplers  100  and  100   b  according to the first or/and second embodiments as described above will be omitted. 
     In the sampler  100  according to the first embodiment of the present invention, both of the swab  110  and the separation unit  200  are replaced and installed to separate and collect airborne bioaerosols having different size ranges. However, in the sampler  100   b  according to the third embodiment, because the first and second swabs  110   a  and  110   b  are respectively installed in the first and second main bodies  120   a  and  120   b  and are respectively connected to the first and second separation units  200   a  and  200   b  unlike the first embodiment, the airborne bioaerosols having different size ranges may be separated and collected without replacing the swab  110  and the separation unit. 
     More particularly, the sampler  100   b  according to the third embodiment may have a form in which the samplers  100  according to the first embodiment are connected as a pair.
