Topic Modeling of Social Networking Service Data on Occupational Accidents in Korea: Latent Dirichlet Allocation Analysis
Authors: Min Kyoung-Bok , Song Sung-Hee , Min Jin-Young 
Published: July 2020

Background
In most industrialized societies, regulations, inspections, insurance, and legal options are established to support workers who suffer injury, disease, or death in relation to their work; in practice, these resources are imperfect or even unavailable due to workplace or employer obstruction. Thus, limitations exist to identify unmet needs in occupational safety and health information.

Objective
The aim of this study was to explore hidden issues related to occupational accidents by examining social network services (SNS) data using topic modeling.

Methods
Based on the results of a Google search for the phrases occupational accident, industrial accident and occupational diseases, a total of 145 websites were selected. From among these websites, we collected 15,244 documents on queries related to occupational accidents between 2002 and 2018. To transform unstructured text into structure data, natural language processing of the Korean language was conducted. We performed the latent Dirichlet allocation (LDA) as a topic model using a Python library. A time-series linear regression analysis was also conducted to identify yearly trends for the given documents.

Results
The results of the LDA model showed 14 topics with 3 themes: workers’ compensation benefits (Theme 1), illicit agreements with the employer (Theme 2), and fatal and non-fatal injuries and vulnerable workers (Theme 3). Theme 1 represented the largest cluster (52.2%) of the collected documents and included keywords related to workers’ compensation (ie, company, occupational injury, insurance, accident, approval, and compensation) and keywords describing specific compensation benefits such as medical expense benefits, temporary incapacity benefits, and disability benefits. In the yearly trend, Theme 1 gradually decreased; however, other themes showed an overall increasing pattern. Certain queries (ie, musculoskeletal system, critical care, and foreign workers) showed no significant variation in the number of queries.

Conclusions
We conducted LDA analysis of SNS data of occupational accident–related queries and discovered that the primary concerns of workers posting about occupational injuries and diseases were workers’ compensation benefits, fatal and non-fatal injuries, vulnerable workers, and illicit agreements with employers. While traditional systems focus mainly on quantitative monitoring of occupational accidents, qualitative aspects formulated by topic modeling from unstructured SNS queries may be valuable to address inequalities and improve occupational health and safety.
Ocurrencia de floraciones nocivas de microalgas en las costas del estado Miranda, Venezuela
Authors: Pereira Carlos Julio 
Published: July 2020

En comunidades de la costa central de Venezuela, ocurren intoxicaciones masivas, que ocasionan mortandad de peces y efectos sobre la salud de personas y animales domésticos. Para entender la dinámica de estos fenómenos, se requiere conocer la estructura comunitaria del fitoplancton durante los eventos. Con apoyo de la comunidad, se captaron muestras de fitoplancton durante tres intoxicaciones masivas ocurridas en los años 2010, 2014 y 2015 y se determinaron variables fisicoquímicas del agua. Como resultado, se obtuvo una comunidad diversa con presencia de diatomeas, dinoflagelados, cianobacterias y euglenofitas con diferencias significativas en la composición durante cada evento. Sin embargo, en las tres intoxicaciones masivas coincide un sobrecrecimiento de dinoflagelados del género Ostreopsis acompañado de la euglenofita Eutreptiella gymnastica, ampliamente conocidos por sus efectos tóxicos en floraciones algales cuando alcanzan densidades superiores a 1.000 células/litro. Al comparar, estas condiciones con aquellas en la que no hay intoxicación, se puede observar que la proporción de la densidad de Ostreopsis con respecto al resto de los dinoflagelados, sobrepasa el 50 %, lo cual pudiera servir de indicador durante las floraciones algales nocivas de estas especies.

Published: July 2020

Este artigo decorre de uma pesquisa de doutorado que investigou a noção de experiência nos artigos sobre a Gestão Autônoma da Medicação no Brasil publicados entre 2011 e 2018. Nele, aborda-se um dos aspectos evidenciados pela pesquisa: a discussão da noção de experiência a partir da perspectiva decolonial, na companhia de autores como Achille Mbembe, Gayatri Spivak e Conceição Evaristo, com o objetivo de aproximar tal discussão das particularidades que dizem respeito à população brasileira quanto ao tema das subalternidades e das relações raciais. Os resultados apontam para a invisibilidade e o silenciamento a respeito de tais questões na produção referente à estratégia GAM durante o período mencionado. Ao mesmo tempo, são localizadas passagens onde os usuários fazem resistência e apresentam saídas para enfrentar a opressão. Assim, reconhece-se na GAM um potencial antirracista que pode vir a se fortalecer.

Published: July 2020

<p><em>The study was conducted to compare the performance of students working in chemistry laboratory with those working in chemistry laboratory supplemented with simulations at secondary school level. The focus of the study was to find out the effectiveness of laboratory work supplemented with simulation on the performance of students. The study was experimental in nature and posttest only control group design was used. Qualitative data is collected by means of interview of chemistry teachers. Quantitative data was also collected and analyzed. The sample comprised of 118 (60 males and 58 female) students and (02) Chemistry teachers of class IX of Public schools of Peshawar. The control group worked in the Chemistry laboratory under normal condition whereas experimental group performed practicals with the help of simulated software. At the end of the treatment practical examination was conducted on the pattern of Peshawar Board of Intermediate and Secondary Education (PBISE). The scores of both control and experimental groups were compared in three main areas i.e. written, viva voce and notebook. For the sake of comparison of control group and experimental group independent sample t-test was used. The result of t-test indicates that there is a significant difference between the performance of control and experimental groups with large effect size. The qualitative data was collected by means of interview which indicated that both the interviewees were motivated and showed keen interest in the simulated software. Both the respondents confirmed that the use of simulated software results in better understanding of concepts in students but at the same time both interviewees reported that it seems difficult to apply the simulated software in our system of Education. The performance of the students of experimental groups showed improvement, results in the rejection of hypotheses that there is no significant difference between the performance of students taught by conventional demonstration in laboratory and laboratory work facilitated with simulation. If proper physical facilities were available simulated software is the solutions of many problems faced by students and teachers in Chemistry laboratories. </em></p>

Experimental investigation on precipitation damage during water alternating flue gas injection
Authors: Wang Zhouhua , Zhang Yuping , Liao Haoqi 
Published: July 2020

Water Alternating Gas (WAG) approach can improve the efficiency of gas flooding. However, the precipitation damage that is induced by the gas injection may be inevitable. The precipitation pressure point test of gas injection, and the WAG parallel double-tube long-core flooding experiment under different injection conditions were systematically performed to obtain the optimum injection parameters. The variations of petrophysical properties were caused by precipitation, and its morphology was also determined by centrifugal capillary force and environmental scanning electron microscope. The precipitation pressure rised with the increase of the amount of gas injection, generally 2.0 MPa ~ 3.0 MPa higher than the bubble point pressure (Pb), and it was confirmed by X-ray energy spectrum and scanning electron microscope that the precipitation was mainly asphaltene. The optimum injection parameters for WAG were Gas–Water Ratio (GWR) of 1:1 and slug size of 0.1 HydroCarbon Pore Volume (HCPV), which benefited the recovery of low-permeability and high-permeability pipe by additional recovery of 28.5% and 17.4% respectively, while WAG process enhanced the total oil recovery by 23.4%. The pore volume and median radius of capillary pressure of all cores were both reduced with more obvious effects on conglomerate. Combined with the results of sediment saturation, it also showed the poorer the physical properties of the cores, the severer the influence of the precipitation. Overall, the WAG could greatly improve the recovery but the influence of precipitation must be considered.

Published: July 2020

We present Swarm-CG, a versatile software for the automatic parametrization of bonded parameters incoarse-grained (CG) models. By coupling state-of-the-art metaheuristics to Boltzmann inversion, Swarm-CG performs accurate parametrization of bonded terms in CG models composed of up to 200 pseudoatomswithin 4h-24h on standard desktop machines, using an AA trajectory as reference and defaultsettings of the software. The software benefits from a user-friendly interface and two different usagemodes (default and advanced). We particularly expect Swarm-CG to support and facilitate thedevelopment of new CG models for the study of molecular systems interesting for bio- and nanotechnology.Excellent performances are demonstrated using a benchmark of 9 molecules of diversenature, structural complexity and size. Swarm-CG usage is ideal in combination with popular CG forcefields, such as e.g. MARTINI. However, we anticipate that in principle its versatility makes it well suited forthe optimization of models built based also on other CG schemes. Swarm-CG is available with all itsdependencies via the Python Package Index (PIP package: swarm-cg). Tutorials and demonstration dataare available at: www.github.com/GMPavanLab/SwarmCG.
Daphnia magna tolerance to toxic cyanobacteria in the presence of an opportunistic infection within an evolutionary perspective

Published: July 2020

In aquatic environments, interactions between cyanobacteria and their grazers are crucial for ecosystem functioning. Cyanobacteria are photosynthetic prokaryotes, which are able to produce large blooms and associated toxins, some of which are able to suppress grazer fitness. Cyanobacterial blooms are intensified by global warming and eutrophication. In our experiments, the tolerance of Daphnia magna (Straus, 1820), an efficient grazer of toxic cyanobacteria, was studied. We used different D. magna clones sampled from different sediment depths, which corresponded to different time periods of eutrophication. Our results showed that different clones had a different tolerance towards the toxic cyanobacterial species, Microcystis aeruginosa, confirming the presence of genetic variation in D. magna tolerance to cyanobacteria. However, there was not a significant adaptive effect of sediment depth. As expected, in general under controlled, infection-free conditions M. aeruginosa reduced D. magna survival. However, a coincidental, non-intended opportunistic fungal infection in a first experiment allowed us to compare the response of D. magna to M. aeruginosa in infected individuals and non-infected individuals (from a second experiment). In the presence of this opportunistic infection, there was no negative effect of M. aeruginosa in the D. magna clones, suggesting that exposure to the infection provided protection for Daphnia individuals towards Microcystis. Biotic interactions can thus be important in the interpretation of cyanobacterial effects in zooplankton grazers and in finding appropriate solutions to reduce the occurrence of cyanobacterial blooms.
La calidad democrática como marco teórico para el estudio de las políticas de comunicación
Authors: Luna Víctor 
Published: July 2020

El impulso de políticas públicas de comunicación durante la última década en América Latina ha incentivado una vigorosa agenda de investigación y despertado interés público en las mismas. Este artículo propone incorporar el enfoque de la calidad democrática para el análisis de dichas políticas. Cuánto pesan los aspectos democráticos en comparación con otros factores de poder dentro del régimen político ha sido una de las preguntas que guían esta propuesta. El artículo invita a repensar las políticas de comunicación incorporando nociones e informes de la calidad democrática con la idea de avanzar en instituciones confiables para el sector de la comunicación. Para eso se exponen conceptos claves para entender qué significa la calidad democrática, cómo puede ser medida a través de indicadores y cómo incorporar a las políticas de comunicación en dicho esquema. A su vez, el trabajo revisa estándares de la regulación de la convergencia digital como la libertad de expresión en Internet, la neutralidad de la red y el acceso a la información y los pone en relación con el objetivo mencionado. Esta propuesta se desprende de una investigación en curso para el nivel de doctorado que analiza la regulación de la convergencia digital durante el kirchnerismo (2003-2015) con especial atención en el estudio de Argentina Digital Ley 27.078.
