Para entender el comportamiento de consumo, sobre todo de distintos segmentos poblacionales, se debe profundizar en sus necesidades, hábitos, deseos, emociones, aspiraciones, motivaciones, experiencias, entre otros elementos propios de cada individuo o grupo etario. El ser humano por naturaleza es influenciable (sigue modas y tendencias culturales), más aun en una era de convivencia digital, acelerada por la pandemia del Covid-19, obligando a instituciones públicas y privadas a re direccionar sus planes estratégicos, en pro de no sacrificar participación en el mercado, acogiendo a la tecnología como su mejor activo funcional, mejorando la sistematización (hardware y software), con herramientas y medios de masificación colectiva para no perder el contacto con los clientes, sobre todo es fases de confinamiento, en una inclusión mutua. Se tomó como objeto de estudio al Ecuador, un país como cualquier otro en tiempos de crisis sanitaria, con necesidades de toda índole, pero con amplios esfuerzos para superarlas. Los hallazgos permitieron conocer cuál es la conducta del consumidor generacional, su grado de adaptación tecnológica y los principales medios de contacto utilizados (redes sociales). El objetivo planteado fue “determinar de qué manera la tecnología influye en el comportamiento de consumo de los distintos grupos etarios de Ecuador”. Aplicando el método deductivo indirecto, sustentado en varias tipologías investigativas, con un instrumento en escala de Likert y el programa IBM SPSS Statistics – 25, se realizó la comprobación de las hipótesis, por medio de coeficiente p (Rho) de Spearman, el cual desplego un grado de correlación alto (0,624) en el supuesto general.
Evaluation of modeled summertime convective storms using polarimetric radar observations
Authors: Shrestha Prabhakar , Trömel Silke , Evaristo Raquel , Simmer Clemens
Published: June 2021

Abstract. Ensemble simulations were conducted for three summertime convective storms over a temperate region in northwestern Germany using the Terrestrial Systems Modeling Platform (TSMP). The simulated microphysical processes were evaluated with polarimetric observations from two X-band radars, with the help of a forward operator applied to the model data. TSMP was found to generally underestimate the convective area fraction, high reflectivities, and the width/magnitude of so-called differential reflectivity (ZDR) columns indicative of updrafts, all leading to an underestimation of the frequency distribution for high precipitation values. The statistical distributions of ZDR and specific differential phase (KDP) were however similar, while the cross-correlation coefficient (phv) was poorly simulated, probably due to little variability of assumed hydrometeor shapes and orientations in the forward operator. The observed model bias in the ZDR columns could be associated with small size of supercooled raindrops and poorly resolved three dimensional flow at km-scale simulations, besides the treatment of freezing process in the model, which warrants further research.
A comparison of contact charging and impact ionization in low-velocity impacts: implications for dust detection in space
Authors: Antonsen Tarjei , Mann Ingrid , Vaverka Jakub , Nouzak Libor , Fredriksen Åshild
Published: June 2021

Abstract. We investigate the generation of charge due to collision between projectiles with sizes below ∼1 µm and metal surfaces at speeds ∼0.1 to 10 km s−1. This corresponds to speeds above the elastic limit and well below speeds where volume ionization can occur. Impact charge production at these low to intermediate speeds has traditionally been described by invoking the theory of shock wave ionization. By looking at the thermodynamics of the low-velocity solution of shock wave ionization, we find that such a mechanism alone is not sufficient to account for the recorded charge production in a number of scenarios in the laboratory and in space. We propose a model of capacitive contact charging that involves no direct ionization, in which we allow for projectile fragmentation upon impact. Furthermore, we show that this model describes measurements of metal–metal impacts in the laboratory well. We also address contact charging in the context of ice-on-metal collisions and apply our results to rocket observations of mesospheric dust. In general, we find that contact charging dominates at speeds of up to a few kilometres per second and complements shock wave ionization up to speeds where direct ionization can take place. The conditions that we consider can be applied to dust particles naturally occurring in space and in Earth's upper atmosphere and their direct impacts on rockets, spacecraft, and impacts of secondary ejecta.
Technical Note: Novel triple O2-sensor aquatic eddy covariance instrument with improved time-shift correction reveals central role of microphytobenthos for carbon cycling in coral reef sands
Authors: Merikhi Alireza , Berg Peter , Huettel Markus
Published: June 2021

Abstract. The aquatic eddy covariance technique stands out as a method for benthic O2-flux measurements because it measures non-invasively, but in the conventional instruments, the spatial separation of the measuring locations of the velocity and O2 sensors causes a time-shift that can be substantial and difficult to correct. Here we introduce a triple O2-sensor-eddy covariance instrument (3OEC) that by positioning of the O2-sensors around the flow measuring volume allows eliminating these time-shifts through signal averaging. The new instrument was used to determine O2-production and consumption in an energetic coastal environment with highly permeable coral reef sands colonized by microphytobenthos. The measurement at ~10 m water depth revealed O2-fluxes that range among the highest reported for marine sediments despite relatively low organic content of the water and coarse sediment, indicating a central role of microphytobenthos for the carbon and nutrient cycling in the coral sand. High light utilization efficiency of the microphytobenthos and bottom currents increasing pore water exchange facilitated the high benthic production and respiration. The measurements documented a gradual transfer of the flux signal from the small turbulence generated at the sediment water interface to the larger wave-dominated eddies of the overlying water column with a delay influenced by the memory effect of eddies. These results demonstrate that the 3OEC can improve the precision of the flux measurements, including measurements in environments considered challenging for this technique, and thereby produce novel insights into the mechanisms that control flux. We consider the fluxes produced by this instrument for the permeable reef sands the most realistic achievable with present day technology.
Arctic sea ice cover data from spaceborne synthetic aperture radar by deep learning
Authors: Wang Yi-Ran , Li Xiao-Ming
Published: June 2021

Abstract. Widely used sea ice concentration and sea ice cover in
polar regions are derived mainly from spaceborne microwave radiometer and
scatterometer data, and the typical spatial resolution of these products
ranges from several to dozens of kilometers. Due to dramatic changes in
polar sea ice, high-resolution sea ice cover data are drawing increasing
attention for polar navigation, environmental research, and offshore
operations. In this paper, we focused on developing an approach for deriving
a high-resolution sea ice cover product for the Arctic using Sentinel-1 (S1)
dual-polarization (horizontal-horizontal, HH, and horizontal-vertical, HV)
data in extra wide swath (EW) mode. The approach for discriminating sea ice
from open water by synthetic aperture radar (SAR) data is based on a
modified U-Net architecture, a deep learning network. By employing an
integrated stacking model to combine multiple U-Net classifiers with diverse
specializations, sea ice segmentation is achieved with superior accuracy
over any individual classifier. We applied the proposed approach to over
28 000 S1 EW images acquired in 2019 to obtain sea ice cover products in a
high spatial resolution of 400 m. The validation by 96 cases of visual
interpretation results shows an overall accuracy of 96.10 %. The S1-derived sea ice cover was converted to concentration and then compared with
Advanced Microwave Scanning Radiometer 2 (AMSR2) sea ice concentration data,
showing an average absolute difference of 5.55 % with seasonal
fluctuations. A direct comparison with Interactive Multisensor Snow and Ice
Mapping System (IMS) daily sea ice cover data achieves an average accuracy
of 93.98 %. These results show that the developed S1-derived sea ice
cover results are comparable to the AMSR and IMS data in terms of overall
accuracy but superior to these data in presenting detailed sea ice cover
information, particularly in the marginal ice zone (MIZ). Data are available

Published: June 2021

Abstract. The composition of mineral, thermal or deep groundwaters is of interest for several geotechnical applications, such as drinking water supply, spas or geothermal energy. A verified and reliable knowledge of temperature, pH, hydrochemical composition and other parameters is crucial to extract fluids with as few technical problems as possible and exploit groundwater reservoirs economically and environmentally sustainable. However, at sites where empirical data are lacking, the correct prediction of fluid properties is often difficult, resulting in considerable economic risks. Here we present the first comprehensive and publicly available database of mineral, thermal and deep groundwaters of Hesse compiled from published and own data. Presently, it contains 1035 datasets from 560 different springs or wells sampled since 1810. A dataset consists of metadata like location, altitude, depth, rock type or stratigraphic unit, information on the water type, references, physical-chemical parameters, concentrations of major, minor and trace elements, content of dissolved and free gases as well as isotope data. The dataset allows the evaluation of time series and distribution of groundwater properties both laterally and vertically. We show a simple statistical evaluation based on the five major hydrogeological regions of Hesse. Our database can be used to re-evaluate genesis and circulation of deep groundwaters, to estimate reservoir temperatures with a solution geothermometer, or to assess groundwater ages by means of isotope data. It can also be useful for a first conception of deep geothermal utilizations. In future, an update and extension of the database is intended.

Abstract. As part of the EUREC4A field campaign, the German research aircraft HALO, configured as a cloud observatory, conducted 15 research flights in the trade wind region east of Barbados in January and February 2020. Narrative text, aircraft state data, and meta data describing HALO's operation during the campaign are provided. Each HALO research flight is segmented by time-stamp intervals into standard elements to aid the consistent analysis of the flight data. Photographs from HALO's cabin and animated satellite images synchronized with flight tracks are provided to visually document flight conditions. As a comprehensive product from the remote sensing observations, a multi-sensor cloud mask product is derived and quantifies the incidence of clouds observed during the flights. In addition, to lower the threshold for new users of HALO's data, a collection of use cases is compiled into an online book "How to EUREC4A", included as an asset with this paper. This online book provides easy access to most of EUREC4A's  HALO data through an intake catalogue.
Model of Early Diagenesis in the Upper Sediment with Adaptable complexity – MEDUSA (v. 2): a time-dependent biogeochemical sediment module for Earth system models, process analysis and teaching
Authors: Munhoven Guy
Published: June 2021

Abstract. MEDUSA is a time-dependent one-dimensional numerical model of coupled early diagenetic processes in the surface sea-floor sediment.
In the vertical, the sediment is subdivided into two different zones.
Solids (biogenic, mineral, etc.) raining down from the surface of the ocean are collected by the reactive mixed layer at the top.
This is where chemical reactions take place.
Solids are transported by bioturbation and advection, and solutes are transported by diffusion and bioirrigation.
The classical coupled time-dependent early diagenesis equations (advection–diffusion reaction equations) are used to describe the evolutions of the solid and solute components here.
Solids that get transported deeper than the bottom boundary of the reactive mixed layer enter the second zone underneath, where reactions and mixing are neglected.
Gradually, as solid material gets transferred here from the overlying reactive layer, it is buried and preserved in a stack of layers that make up a synthetic sediment core. MEDUSA has been extensively modified since its first release from 2007.
The composition of the two phases, the processes (chemical reactions) and chemical equilibria between solutes are not fixed any more, but get assembled from a set of XML-based description files that are processed by a code generator to produce the required Fortran code.
1D, 2D and 2D×2D interfaces have been introduced to facilitate the coupling to common grid configurations and material compositions used in biogeochemical models.
MEDUSA can also be run in parallel computing environments using the Message Passing Interface (MPI).
Seasonality of density currents induced by differential cooling
Authors: Doda Tomy , Ramón Cintia L. , Ulloa Hugo N. , Wüest Alfred , Bouffard Damien
Published: June 2021

Abstract. When lakes experience surface cooling, the shallow littoral region cools faster than the deep pelagic waters. The lateral density gradient resulting from this differential cooling can trigger a cold downslope density current that intrudes at the base of the mixed layer during stratified conditions. This process is known as thermal siphon (TS). TS flushes the littoral region and increases water exchange between nearshore and pelagic zones, with possible implications on the lake ecosystem. Past observations of TS in lakes are limited to specific cooling events. Here, we focus on the seasonality of the TS-induced lateral transport and investigate how the seasonally varying forcing conditions control the occurrence and intensity of TS. We base our analysis on one year of observations of TS in Rotsee (Switzerland), a small wind-sheltered temperate lake composed of an elongated shallow region. We demonstrate that TS occurs for more than 50 % of the days from late summer to winter and efficiently flushes the littoral region in ~10 hours. We further quantify the seasonal evolution of the occurrence, intensity and timing of TS. The conditions for the formation of TS are optimal in autumn, when the duration of the cooling phase is longer than the initiation timescale of TS. The decrease in surface cooling by one order of magnitude from summer to winter reduces the lateral transport by a factor of two. We interpret this transport seasonality with scaling relationships relating the daily averaged cross-shore velocity, unit-width discharge and flushing timescale to the surface buoyancy flux, mixed layer depth and lake bathymetry. The timing and duration of the diurnal flushing by TS are associated with the duration of the daily heating and cooling phases. The longer cooling phase in autumn increases the flushing duration and delays the time of maximal flushing, compared to the summer period. Our findings based on scaling arguments can be extended to other aquatic systems to assess, at a global scale, the relevance of TS in lakes and reservoirs.
Gravity as a tool to improve the hydrologic mass budget in karstic areas
Authors: Pivetta Tommaso , Braitenberg Carla , Gabrovšek Franci , Gabriel Gerald , Meurers Bruno
Published: June 2021

Abstract. Monitoring the water movements in karstic areas is a fundamental but challenging task due to the complexity of the drainage system and the difficulty in deploying a network of observations. Gravimetry offers a valid complement to classical hydrologic measurements in order to characterize such systems in which the recharge process causes temporarily accumulation of large water volumes in the voids of the epi-phreatic system. We show an innovative integration of gravimetric and hydrologic observations that constrains a hydrodynamic model of the Škocjan cave system (Slovenia). We demonstrate how the inclusion of gravity observations improves water mass budget estimates for the Škocjan area based on hydrological observations only. Finally, the detectability of water storage variations in other karstic contexts is discussed with respect to the noise performances of spring and super-conducting gravimeters.

Published: June 2021

Abstract. The TIR100-2 emissometer (manufactured by Inglas GmbH & Co.KG) is an emissivity measurement device used by several producers of thermal insulation products for buildings and by some organizations certifying performance of insulation products. A comparison of emissivity measurements on low-emissivity foils involving different measurement techniques, including the TIR100-2 emissometer, gave widely dispersed results; the discrepancies were
not explained. The metrological performance of the TIR100-2 emissometer and the uncertainties for measurement on reflective foils was not known, which could be detrimental to users. In order to quantify the performance of TIR100-2 devices for measurement of total near-normal emissivity of low-emissivity foils, the Laboratoire National de Métrologie et d'Essais (LNE) analyzed in detail the measuring principle and listed the associated assumptions and uncertainty sources. A TIR100-2
emissometer actually measures the reflectance and, for opaque materials, the emissivity is calculated from the measured reflectance. The parameters
analyzed experimentally are the temperature stability and uniformity of the thermal radiation source, the emissivity of the radiation source, the
response function linearity and the spectral sensitivity of the radiometric detection system measuring the reflected radiation, the size of the
measurement area, and the measurement repeatability and reproducibility. A detailed uncertainty budget was established. The uncertainty sources taken into account are the uncertainties of the emissivities of the two calibrated standards used for calibration, the stability and uniformity of the
radiation source temperature, the non-linearity and the spectral sensitivity of the radiometric detection system, the specific measurement condition
related to the radiation source temperature, the uncertainties related to the temperatures of the standards and the sample, the noises on results, and the non-homogeneity in emissivity of the tested material. The combined measurement uncertainty was calculated for different types of reflective
foils; the expanded uncertainty is around 0.03 for total near-normal emissivity measurements on smooth low-emissivity foils. A measurement campaign on five types of low-emissivity foils, involving four TIR100-2 emissometers, and a comparison to a primary reference setup at the Physikalisch-Technische Bundesanstalt (PTB) confirmed the uncertainties assessed.
Landslide risk management analysis on expansive residential areas – case study of La Marina (Alicante, Spain)
Authors: Cantarino Isidro , Carrion Miguel Angel , Palencia-Jimenez Jose Sergio , Martínez-Ibáñez Víctor
Published: June 2021

Abstract. Urban expansion is a phenomenon that has been observed since the mid-20th
century in more developed regions. One aspect of it is the urban development
of holiday resorts with second homes that generally appeared following world
political stabilisation. This residential expansion has often happened with
scarce control, especially in its early stages, allowing areas to be occupied
that are not so suitable in terms of the environment, culture and landscape,
not to mention the very geological risks of flooding, earthquakes and
landslides. Indeed, the risk of landslides for buildings occupying land in
zones at such risk is not a matter solely attributable to the geomorphological
characteristics of the land itself, nor is it simply a question of chance; it
is also due to its management of such land, generally because of a lack of
specific regulations. This study aims to lay down objective criteria to find
how suitable a specific local entity's risk management is by looking at the
evolution of its urban development procedures. It also aims to determine what
causes the incidence of landslide risk (geomorphology, chance, land
management, etc.) and finally to suggest control tools for the public bodies
tasked with monitoring such matters.
Fractionation of O2/N2 and Ar/N2 in the Antarctic ice sheet during bubble formation and bubble-clathrate hydrate transition from precise gas measurements of the Dome Fuji ice core

Published: June 2021

Abstract. The variations of δO2/N2 and δAr/N2 in the Dome Fuji ice core were measured from 112 m (bubbly ice) to 2001 m (clathrate hydrate ice) at high precision. Our method, combined with the low storage temperature of the samples (−50 °C), successfully excludes post-coring gas-loss fractionation signals from our data. From the bubbly ice to the middle of the bubble-clathrate transition zone (BCTZ) (112–800 m) and below the BCTZ (> 1200 m), the δO2/N2 and δAr/N2 data exhibit orbital-scale variations similar to local summer insolation. The data in the lower BCTZ (800–1200 m) have large scatters, which may be caused by mm-scale inhomogeneity of air composition combined with finite sample lengths. The insolation signal originally recorded at the bubble close-off remains through the BCTZ, and the insolation signal may be reconstructed by analyzing long ice samples. In the clathrate hydrate zone, the scatters around the orbital-scale variability decrease with depth, indicating diffusive smoothing of δO2/N2 and δAr/N2. A simple gas diffusion model was used to reproduce the smoothing and thus constrain their permeation coefficients. The relationship between δAr/Ν2 and δO2/N2 is markedly different for the datasets representing bubble close-off (slope ~0.5), bubble-clathrate hydrate transformation (~1), and post-coring gas-loss (~0.2), suggesting that the contribution of the mass-independent and mass-dependent fractionation processes are different for those cases. The method and data presented here may be useful for improving the orbital dating of deep ice cores over the multiple glacial cycles and further studying non-insolation-driven signals (e.g., atmospheric composition) of these gases.
Modelling the mass budget and future evolution of Tunabreen, central Spitsbergen
Authors: Oerlemans Johannes , Kohler Jack , Luckman Adrian
Published: June 2021

Abstract. Tunabreen is a 26-km long tidewater glacier. It is the most frequently surging glacier in Svalbard, with four documented surges in the past hundred years. We have modelled the evolution of this glacier with a Minimal Glacier Model (MGM), in which ice mechanics, calving and surging are parameterized. The model geometry consists of a flow band to which three tributaries supply mass. The calving rate is set to the mean observed value for the period 2012–2019, and kept constant. For the past 120 years, a smooth Equilibrium Line Altitude (ELA) history is reconstructed by finding the best possible match between observed and simulated glacier length. There is a modest correlation between this ELA history and meteorological observations from Longyearbyen. The simulated glacier retreat is in good agreement with observations. Runs with and without surging show that the effect of surging on the long term glacier evolution is limited. Due to the low surface slope and associated strong height -mass balance feedback, Tunabreen is very sensitive to changes in ELA. For a constant future ELA equal to the reconstructed value for 2020, the glacier front will retreat by 8 km during the coming hundred years. For an increase of the ELA of 2 m per year, the retreat is projected to be 13 km and Tunabreen becomes a land-based glacier around 2100. The calving rate is an important parameter: increasing its value by 50 % has about the same effect as a 50 m increase in the ELA, the corresponding equilibrium glacier length being 18 km (as compared to 25.8 km in the reference state). Response times vary from 150 to 400 years, depending on the forcing and on the state of the glacier (tidewater or land-based).

Published: June 2021

International education has become an essential component of Chinese universities, and its importance is growing as a result of government funding. Academic exchange and collaboration with international universities are becoming more relevant in Chinese universities. This research aimed to develop a holistic understanding of international students’ perceptions of socioeconomic, cultural, and intellectual issues in China. The study was qualitative, and semi-structured interviews were conducted. Five international students were recruited from different schools of the normal university, and all were from different countries. The overall cultural difference did not affect their life in china. The learning environment in a normal university was good—Chinese Language, a big problem everyone suffered. Availability of English language instructions in the university offices, canteens, etc. found very low. Course instructions need to improve. English taught programs should have full access to English Teaching Learning. Chinese and International student’s classes should be together for better interaction and language learning.
EFFECT OF FRICTION ON THE MICROMECHANICAL PROPERTIES OF AISI 316L AUSTENITIC STEEL

In this paper, we investigate the possibility of using the friction method for modifying the microstructure and mechanical properties in the near-surface regions of AISI 316L austenitic steel specimens for the purpose of its practical application. It is shown that a region of severe plastic deformation arises near the friction surface, which transforms the initial fine-grained polycrystalline steel structure into a homogenized zone consisting of a deformed structure with plastic slip bands and weakly pronounced grain boundaries. The change in the microscopic structure results in an increase in this zone of values of micromechanical characteristics, such as microhardness (H), Young's modulus (E), plasticity index (H/E) and resistance index (H3/E2). The obtained results are of interest for the potential use of AISI 316L steel in medicine.

В статье рассматривается изменение свойств залежных черноземов на территории Ракитянского и Ровеньского районов Белгородской области, деградированных в результате антропогенной деятельности. Эти два района были выбраны для сравнения, т.к. находятся в разных физико-географических и почвенно-географических условиях и отличаются по климату, рельефу, эрозионному потенциалу. На объектах исследования в каждом районе было заложено по 7 разрезов. Для каждого разреза отобраны образцы почв новообразованного (АUра), нижележащего горизонта (PU) и близлежащей пашни со сходными почвенными ситуациями, выполнено подробное описание почвенного профиля. Были описаны морфологические признаки почвенных горизонтов и подгоризонтов, а также посредством полевых методов установлены показатели их физических свойств. Исследованы физико-химические свойства изучаемых объектов. Было выявлено, что для всех исследуемых объектов восстановленный горизонт отличается от подпахотного и сравниваемой пашни в лучшую сторону практически по всем исследованным физико-химическим свойствам. Установлены зависимости некоторых физико-химических свойств от территориального расположения объектов. Например, для таких показателей как содержание гумуса, ёмкость катионного обмена, рН, соотношение содержания углерода и азота (С/N) принадлежность разрезов к восточной или западной части области играет значительную роль и влияет на показатели. Для гидролизуемого и валового азота, лабильного гумуса, показателей фосфора и калия заметных различий не наблюдается. Таким образом, данное исследование подтверждает возможность использования естественных механизмов воспроизводства почвы применимо к территории лесостепной и степной зон Белгородской области.

Зоонозные инфекционные заболевания (природно-очагового характера) представляют серьезную угрозу здоровью и санитарно-эпидемиологическому благополучию населения. Стойкость природных очагов, непрогнозируемое и даже непредсказуемое возрастание их активности, обусловливают рост заболеваемости среди людей, обостряя медико-экологическую ситуацию в отдельных регионах и странах в целом. Несмотря на достигнутые ранее результаты изучения ландшафтно-географических и социально-экономических условий территории Северо-Казахстанской области (СКО) и их влияния на комфортность проживания с медико-географической точки зрения, комплексные репрезентативные медико-географические исследования природно-очаговых заболеваний на территории региона не проводились. Целью данного исследования является изучение особенностей пространственно-временного проявления природно-очаговых заболеваний на территории СКО. В результате исследования были выявлены природные предпосылки проявления природно-очаговых болезней на территории региона, основные тенденции в развитии зоонозных инфекционных заболеваний на территории СКО, выделены территории с повышенным (Кызылжарский, Айыртауский районы, г. Петропавловск) и пониженным (Акжарский, Уалихановский районы) риском проявления. Полученные результаты вносят практический вклад в развитие медицинской географии Казахстана, электронная база данных ГИС может быть включена в систему медико-экологического мониторинга природно-очаговых болезней на территории СКО.

There is tremendous interest in the use of probiotics to treat gastrointestinal diseases such as irritable bowel syndrome (IBS), but significant limitations to the research, lack of regulation of the probiotic market, and limited education surrounding probiotics have led to confusion and misinformation. In this article, we summarize our #TuesdayNightIBS discussion on the current state of affairs in probiotics research as it relates to IBS. We include a compilation of evidence based strains and combinations of strains specifically for IBS, and provide suggestions and resources that relate to the prescribing of probiotics for IBS.

To assess the fall of risk among the elderly in selected urban area of Thrissur. Objectives a) To assess the fall risk among the elderly people in selected urban area of Kachery, Thrissur. b) To associate fall risk score with selected demographic variables. c) To correlate fall risk assessment questionnaire score and modified fall prevention checklist for personal risk factors score among elderly individuals. d) To teach the elderly people about fall prevention exercise. Methodology: Non-experimental descriptive research design is adopted in this study. We selected 60 samples through random sampling technique. Standardized fall risk assessment questionnaire built by national aging research institute and modified fall prevention checklist for personal risk factors built by Hamilton county was used to collect the data. Tool was administered by interview method for assessing fall risk. Fall preventive intervention module developed, validated and administered following data collection. The data collected were analyzed by using descriptive and inferential statistics. Result: The demographic profile of elderly people shows that 46.66% belongs to age group between 60-70 years and most of them 58.33% were females. The majority 73.33% of elderly person are at low risk for fall and 26.66% are at high risk for fall in questionnaire and 81.67% of elderly are low risk for fall, 18.33% are risk and there is no elderly person high risk for fall in checklist. The overall fall risk is high among elderly individual alone in home and low in elderly in nuclear families. The risk for fall among elderly based on previous history of fall shows that elderly with visual impairment those who don’t have previous knowledge about fall prevention and elderly age between 91-100 is high risk for fall. The risk for fall based on ability to perform ADL in elderly shows those who living alone in the home high risk for fall. There is significant association between score with selected variables like age, previous knowledge about fall prevention, elderly residing in their home alone. We found that there is perfect positive correlation r=1 between fall risk assessment, questionnaires and checklist score. Discussion: At the end of the study the investigator found that the risk for fall based on the assessment of fall history among elderly people shows that, there is significant association between age (p=0.0273) that is, age group between 91-100 years are high risk for fall. Previous knowledge about fall prevention shows that, elderly without previous knowledge about fall prevention is at high risk for fall (p= 0.03074). In sensory impairment that is, elderly having visual impairment (p=0.998) having risk for fall. The risk for fall among elderly people based on their ability to perform activities of daily living shows that, elderly residing in their home alone shows more risk for fall.

Penelitian ini bertujuan untuk mengetahui alur proses bisnis mulai dari surat edaran dari Kemendikbud tentang pelaksanaan proposal PKM sampai dengan monitoring unggah proposal PKM ke SIMBELMAWA yang dilakukan oleh para mahasiswa UPN Veteran Jakarta. Unggah proposal PKM yang dilakukan oleh mahasiswa angkatan tahun 2016 dan seterusnya ke SIMBELMAWA merupakan syarat untuk menyusun proposal skripsi. Hasil pengamatan yang dilakukan oleh peneliti di dua fakultas, yaitu Fakultas Ilmu Komputer dan Fakultas Ilmu Kesehatan, kelompok mahasiswa yang mengunggah proposal PKM ke SIMBELMAWA tidak mengetahui harus melaporkan kepada siapa bahwa proposal PKM telah diunggah. Dengan demikian Keputusan Rektor Nomor: KEP./142/UN61/2019 tentang Kewajiban Mahasiswa Tahun Angkatan 2016 dan seterusnya menjadi tidak efektif jika tidak ada personel maupun sistem yang mengontrol. Penelitian ini dilakukan dengan menggunakan diagram flowmap dan diharapkan dapat memberikan solusi bagi institusi dalam menangani permasalahan tersebut, sehingga monitoring maupun evaluasi dapat dilakukan secara efektif dan efisien.
