Authors: Navas Fernández María José , Ramírez Arcos Diana Paola
Published: July 2019

Las bacterias son los patógenos principales relacionados con infecciones que afectan las estruc¬turas del ojo de forma intra- o extraocular; el género Staphylococcus es el grupo más prevalente asociado con este tipo de infección. Para el control de las infecciones oculares se utilizan an¬tibióticos como oxacilina y meticilina, que en muchos casos llevan a la resistencia bacteriana. Además, el alto costo de los medicamentos, que en Colombia alcanzan cifras tres o cuatro veces mayores que en otros países, se constituyen en desventajas para su uso. Lo anterior ha llevado a estudiar la actividad antimicrobiana de las plantas frente a los microorganismos asociados a las infecciones oculares bacterianas. El propósito de este artículo de revisión es conocer los beneficios potenciales de las plantas o sus productos para el control de estas infecciones como una alternativa para su tratamiento.

Published: July 2019

Los anfibios y reptiles son organismos indispensables para el buen funcionamiento de los ecosistemas naturales, pero en décadas recientes han declinado en número y distribución por varios factores, entre los que destacan los antropogénicos. Por otro lado, la pérdida de conocimiento biocultural puede modificar la percepción que se tiene de estos organismos y llevar a una difícil coexistencia. Este trabajo tiene como objetivo caracterizar el conocimiento etnozoológico sobre la herpetofauna que tienen los pobladores de la comunidad maya de Santa Elena, Yucatán. De junio a octubre de 2016 se aplicaron 145 cuestionarios mixtos y dos entrevistas semiestructuradas a informantes clave. Como resultado sabemos que los habitantes de la comunidad maya de Santa Elena reconocen 68 especies (12 anfibios y 56 reptiles), de las cuales 31 son consideradas como venenosas. Se recopilaron 44 relatos, en los cuales la serpiente cascabel, en maya tsab kan (Crotalus tzabcan) fue la especie que obtuvo el mayor número de menciones (23%). De las especies registradas en el trabajo, 13 presentan algún tipo de uso. El medicinal fue el más mencionado para la serpiente cascabel (C. tzabcan) (53.1%) y la tortuga de caja, en maya, Xkok ak (Terrapene yucatana) (25.5%) y el uso alimenticio para la iguana, en maya tolok, C (Ctenosaura similis) (42%). Estos resultados reflejan la importancia de incluir el conocimiento local para mejorar las medidas de conservación de este grupo biológico.

The humanitarian tragedy through a series of bombings carried out byone family, such as a willingness to be disguised for their actions as notto seek an attention, and the use of children in the acts of terrorism tosacrifice all family members, this has never happened in any part of theworld which have swallowed recent casualties and property lossesoccurred in Surabaya, became a highlight for all Indonesian people andthe world as well. The growth of radicalism eventually shows the face ofviolence in Indonesia, this terrorism movement is intended as a form ofresistance, in carrying out its actions solely as a jihad to uphold the truththey believe in. The basis and purpose of their foundation is religion, butthe religion which is narrowly understood and packaged in such a waybecomes a radical ideology of resistance. It does not mean that terroristactivists of jihad are lack of education, some of them are smart peoplebut they are frustrated by the socio-political hegemony of secularhedonicculture. Terror is still one of the ways to express radicalism, aterror which is motivated by religious ideology and dissatisfaction, isvery dangerous due to an excessive individual fanaticism and willingnessto sacrifice oneself in achieving the goals.

Few decades onwards decision-making systems have underwent many changes with the new technologies of Data warehouse/Data Mining. The tendency in OLAP data plays an important role on Business Intelligence over OLTP data, i.e., day to day data. Business Intelligence is not just for big organizations, but it is a simple technology that can be used by small and medium enterprises (SMEs) too for better results in their businesses. The main intention of this paper is to describe the usage of BI and how it is useful to the organizations in decision making. BUSINESS INTELLIGENCE (Bl) is one of the simplest technology to understand. However, getting it into the right direction is the most difficult tasks for both small and large companies. In simple terms, Bl is all about taking the volume of data that every company collects on daily basis and present it in a form that can be understood by the decision makers. The ability to use historical information to make business decisions are the fundamental basis of a business. Transforming data into information and bringing together disparate sources of valuable information to analyse BI can enable SMEs to gain timely access to high quality, reliable business data and metrics. That enables them to make better-informed decisions while dealing with customers, suppliers or internal processes. Fundamentally, BI enables companies to more easily identify and reduce the cost and also to take guesswork out of decisions that help drive top-line revenue growth.

Authors: AMANAF MUNTAQO ALFIN
Published: July 2019

IT Telkom Purwokerto (ITTP) merupakan salah satu perguruan tinggi yang memanfaatkan jaringan WiFi untuk civitas akademiknya. Namun pada beberapa area masih terdapat pengguna yang mendapatkan kuat sinyal dengan kategori buruk. Dari jumlah access point (AP) existing sebanyak 15 AP masih terdapat area yang belum ter-cover jaringan WiFi dengan baik. Hal tersebut dibuktikan dengan hasil simulasi AP existing yang menunjukan nilai Receive Signal Level (RSL) pada lantai 2 dan lantai 3 sebesar -74 dBm dan -79 dBm dimana nilai RSL tersebut dikategorikan buruk sehingga perlu dilakukan optimasi penempatan access point pada gedung penelitian. Penelitian ini melakukan perhitungan coverage (cakupan wilayah) dengan metode COST 231 Multi wall model dan capacity (kapasitas pengguna) dengan metode OBQ untuk mendapatkan jumlah AP. Berdasarkan perhitungan, didapatkan jumlah AP sebanyak 26 AP dari perhitungan coverage dan 20 AP dari perhitungan capacity. Dari jumlah AP yang didapatkan kemudian disimulasikan menggunakan simulator RPSv5.4 dengan frekuensi 2,4 GHz dan model propagasi COST 231 Multiwall. Untuk mengetahui jumlah AP dan penempatan AP yang optimal maka dilakukan perbandingan 4 skenario penempatan dengan melihat hasil parameter RSL dan Signal Interference Ratio (SIR). Hasil yang didapat berdasarkan perhitungan, terdapat penambahan jumlah AP dari 15 AP menjadi 26 AP serta pergeseran letak AP agar seluruh area ter-cover dengan baik. Dari hasil RSL dan SIR pada simulasi optimasi, jumlah AP yang optimal yaitu 26 AP dengan posisi AP ditempatkan ditepi bagian depan dengan hasil RSL pada keseluruhan lantai sebesar -27,27 dBm dan SIR sebesar 4,05 dB.
Omega 3 Fatty Acids and Neurodegenerative Diseases: New Evidence in Clinical Trials
Authors: Avallone Rossella , Vitale Giovanni , Bertolotti Marco
Published: July 2019

A nutritional approach could be a promising strategy to prevent or slow the progression of neurodegenerative diseases such as Parkinson’s and Alzheimer’s disease, since there is no effective therapy for these diseases so far. The beneficial effects of omega-3 fatty acids are now well established by a plethora of studies through their involvement in multiple biochemical functions, including synthesis of antinflammatory mediators, cell membrane fluidity, intracellular signalling and gene expression. This systematic review will consider epidemiological studies and clinical trials that assessed the impact of supplementation or dietary intake of omega-3 polyunsaturated fatty acids on neurodegenerative diseases such as Parkinson’s and Alzheimer’s diseases. Indeed, treatment with omega-3 fatty acids, being safe and well tolerated, represent a valuable and biologically plausible tool in the management of neurodegenerative diseases in their early stages.

Authors: Yun Kyongsik , Choi Jaekyu , Song In-Uk , Chung Yong An
Published: July 2019

Managing blood cholesterol levels is important for the treatment and prevention of diabetes, cardiovascular disease, and obesity. An easy-to-use, portable cholesterol blood test will accelerate more frequent testing by patients and at-risk populations. We aim to evaluate the performance of smartphone-based point-of-care cholesterol blood tests as compared to that of hospital-grade laboratory tests. We used smartphone systems that are already familiar to many people. Because smartphone systems can be carried around everywhere, blood can be measured easily and frequently. We compared the results of cholesterol tests with those of existing clinical diagnostic laboratory methods. We found that smartphone-based point-of-care lipid blood tests are as accurate as hospital-grade laboratory tests (N=116, R>0.97, P<0.001 for all 3 cholesterol blood tests: total cholesterol, high density lipoprotein, and triglyceride). Our system will be useful for those who need to manage blood cholesterol levels to motivate them to track and control their behavior.

Authors: Qiu Xiulin , Liu Qinghua , Li Ru
Published: July 2019

The real time kinematic of global positioning system (GPS-RTK) provides precise positioning for bridge deformation monitoring and monitoring bridge health status. In order to solve the problem that the satellite signal is vulnerable to the influence of the positioning environment when monitoring bridges in the valleys and urban buildings[1], and the problem that Kalman fusion algorithm is difficult to detect the divergence caused by interruption or wrong data[2]. This paper proposes an improved Kalman filter fusion position method based on the BD/GPS fusion positioning. This improved algorithm introduces the environmental information. The confidence level is calculated with membership function by defining the confidence region of sensor, so as to the fusion weight coefficient is determined. This paper analyzes the performance of BD/GPS positioning in bridge monitoring through comparing the traditional fusion method with the improved fusion method. Experiments show that the improved algorithm eliminates the problem of error divergence; the average number of visible satellites in BD/GPS fusion positioning is increased by 7 compared with that of GPS single system positioning, the GDOP value is reduced by 21.83%, and the positioning error is reduced by 2.51 cm. The feasibility of all-weather monitoring in the mountains, buildings and other areas is verified, and millimeter accuracy is provided, which greatly improves the performance of bridge deformation monitoring.

Authors: Wijana Katon
Published: July 2019

To insert new data into a database table using a web-based application, a graphical user interface in the form of HTML Form is required. Each table field / attribute requires an appropriate form control in order to minimize data errors that will be entered. There is a relation between the data type of a field in the table with the type of form control to be used, therefore the graphical user interface in the form of HTML Form can be created automatically.  There are various control forms of HTML in the form of tags, generally in the form of input tags. What distinguishes the form control from one to another is the attribute: type, size, value therefore to determine the type and content of form controls can be given through parameters.  HTML Form can be regarded as an object which has many other objects in the form of form controls. Object Oriented Programming (OOP) paradigm it can be implemented to build HTML Form.  Through meta data from a table, it will be able to obtain the appropriate HTML form control, but for each specific data type it can have the appropriate form control candidate, therefore before Form HTML is created by the generator, there should be a little user intervention to get the interface The desired HTML form.

Sulfonic Acid-Functionalized Magnetic Nanoparticles as an Efficient Catalyst for the Synthesis of Benzo[4, 5]imidazo[1, 2-a]pyrimidine Derivatives, 2-Aminobenzothia Zolomethylnaphthols and 1-Amidoalkyl-2-naphthols
Authors: Damghani Fatemeh K. , Pourmousavi Seied A. , Kiyani Hamzeh
Published: July 2019

Background:

Carbon-based sulfonated catalysts have several advantages but their separation by filtration is still a challenge. On the other hand, the synthesis of magnetic sulfonated carbon nanoparticle indicated that the magnetic separation could be an efficient way to separate the catalyst from the reaction mixture.

Objective:

In order to synthesize a separable magnetic Fe3O4@C-SO3H nanoparticle (MNPs) with high catalytic activity in organic transformation, three environmental-benign and low-cost sulfonic acidfunctionalized magnetic nanoparticle (Fe3O4@C-SO3H) were successfully synthesized.

Materials and Methods:

The Nano catalysts were prepared by solvothermal carbonization of Sucrose (Suc), Starch (Sta) or Cellulose (Cel) in the presence of Fe3O4 Nanoparticle and then grafting of the sulfonic groups on the surface of resulted Fe3O4@C nanoparticles in the presence of p-Toluenesulfonic. Then the Nano catalysts were characterized using XRD, FESEM and FT-IR.

Results:

Three Fe3O4@C-SO3H were successfully synthesized. The resulted MNPs were used for the synthesis of benzo [4, 5] imidazo[1, 2-a]-pyrimidine derivatives, 2/-aminobenzothiazolomethylnaphthols and 1-amidoalkyl-2-naphthols under solvent-free conditions in excellent yields. It was found that high catalytic activity and easy magnetic separation from the reaction mixture are important achievement with regard to the efficiency and reusability of the catalyst in synthesis.

Conclusion:

The MNPs were synthesized and used as an efficient catalysts for the one-pot synthesis of benzo [4, 5] imidazo[1, 2-a]-pyrimidine derivatives, 2/-aminobenzothiazolomethylnaphthols, and 1-amidoalkyl-2- naphthols under solvent-free conditions in excellent yields. High catalytic activity and easy magnetic separation from the reaction mixture are two factors for evaluating the performance of Fe3O4@C-SO3H nanoparticles in the organic transformations.

In the current work, a two-step AgNP synthesis process was optimized at the mycelia-DI
water suspension and AgNP formation reaction levels.

Results:

Biomass filtrate from the fungal strain Tritirachium oryzae W5H was able to reduce silver
nitrate into AgNPs after a 72 h reaction, as indicated by the development of intense brown color and
by UV-vis spectra. The biosynthesis ability of AgNPs was markedly better in the presence of a single
carbon and nitrogen source in the culture medium compared to multiple sources of carbon and nitrogen.
The optimization results of AgNP formation were indifferent between the two steps and were 20
g biomass, 40°C, pH 7.0, 96 h and 1.0 mM AgNO3. The TEM images of the prepared AgNPs illustrated
the presence of 7-75 nm, monodispersed and spherical- to ovular-shaped Ag nanoparticles.

Conclusion:

The present work highlights the importance of investigating the process parameters by
which the reductant mycelia-free filtrate was prepared. In addition, we explored the promising antibacterial
action of the prepared AgNPs against bacterial infections.
A gyermekvállalás árnyékára és a teljes termékenységi ráta Magyarországon?
Authors: Pásztor Szabolcs
Published: July 2019

Magyarországon a teljes termékenységi ráta a rendszerváltás óta meredeken csökken. Az arányszám ráadásul az 1980-as évek második fele óta messze elmarad a reprodukciós szinttől, a népességszám 1980 óta fogy. Releváns tehát a kérdés, hogy milyen tényezők húzódhatnak meg a ráta tartósan alacsony szintje és továbbra is csökkenő trendje mögött. Cikkemben Walker (1995) nyomán elkészítem a gyermekvállalás árnyékárának idősorát Magyarországra, amellyel empirikus adatok alapján becslést adok az első gyer-mek vállalása következtében felmerülő költségekre. Bemutatom az összefüggést a teljes termékenységi ráta alakulása és az átlagos anyai életkor kitolódása között. Az ütem és paritás szerint korrigált teljes termékenységi rátát először az árnyékárak idősorainak segítségével vizsgálom, majd parciális elemzésnek vetem alá. Az eredmények alapján ajánlásokat fogalmazok meg a gazdaságpolitikai döntéshozó számára a termékenység pozitív irányú ösztönzésére vonatkozóan.

Finding Warning Markers: Leveraging Natural Language Processing and Machine Learning Technologies to Detect Risk of School Violence (Preprint)
Authors: Ni Yizhao , Barzman Drew , Bachtel Alycia , Griffey Marcus , Osborn Alexander , Sorter Michael
Published: July 2019

BACKGROUND

School violence has a far reaching effect, impacting the entire school population including staff, students and their families. Among youth attending the most violent schools, studies have reported higher dropout rates, poor school attendance, and poor scholastic achievement. It was noted that the largest crime-prevention results occurred when youth at elevated risk were given an individualized prevention program. However, much work is needed to establish an effective approach to identify at-risk subjects.

OBJECTIVE

In our earlier research, we developed a standardized risk assessment program to interview subjects, identify risk and protective factors, and evaluate risk for school violence. This study focused on developing natural language processing (NLP) and machine learning technologies to automate the risk assessment process.

METHODS

We prospectively recruited 131 students with behavioral concerns from 89 schools between 05/01/2015 and 04/30/2018. The subjects were interviewed with three innovative risk assessment scales and their risk of violence were determined by pediatric psychiatrists based on clinical judgment. Leveraging NLP technologies, different types of linguistic features were extracted from the interview content. Machine learning classifiers were then applied to predict risk of school violence for individual subjects. A two-stage feature selection was implemented to identify violence-related predictors. The performance was validated on the psychiatrist-generated reference standard of risk levels, where positive predictive value (PPV), sensitivity (SEN), negative predictive value (NPV), specificity (SPEC) and area under the ROC curve (AUC) were assessed.

RESULTS

Compared to subjects' demographics and socioeconomic information, use of linguistic features significantly improved classifiers' predictive performance (P<0.01). The best-performing classifier with n-gram features achieved 86.5%/86.5%/85.7%/85.7%/94.0% (PPV/SEN/NPV/SPEC/AUC) on the cross-validation set and 83.3%/93.8%/91.7%/78.6%/94.6% (PPV/SEN/NPV/SPEC/AUC) on the test data. The feature selection process identified a set of predictors covering the discussion of subjects' thoughts, perspectives, behaviors, individual characteristics, peers and family dynamics, and protective factors.

CONCLUSIONS

By analyzing the content from subject interviews, the NLP and machine learning algorithms showed good capacity for detecting risk of school violence. The feature selection uncovered multiple warning markers that could deliver useful clinical insights to assist personalizing intervention. Consequently, the developed approach offered the promise of an end-to-end computerized screening service for preventing school violence.
Tendencias y perspectivas de la investigación urbana en América Latina
Authors: Valencia Enrique , Jablonska Alexandra
Published: July 2019

Las investigaciones sobre urbanización deben considerarse como parte de formulaciones más amplias, tendientes a explicar todo un "sistema social" o formación determinada. Y la existencia de diferentes enfoques epistemológicos y métodos se debe al desarrollo mismo de la investigación en América Latina, como una serie de prácticas teóricas e ideológicas insertas en una detrminada estructura social y momento histórico.

La nueva estrategia contrainsurgente en El Salvador
Authors: Sánchez Ramos Irene
Published: July 2019

El año de 1986 abre en El Salvador una nueva etapa en lo que toca a los aspectos de contrainsurgencia. Es a partir de esa fecha en que ésta adquiere una globalidad de la que había carecido desde el inicio de la operatividad de la guerrilla en el país. Hasta ahora el ejército salvadoreño no había logrado conformar un esquema para enfrentar a la insurgencia donde, tanto los elementos políticos y económicos como los militares, convergieran en un mismo esfuerzo de carácter nacional.
