Online Information Exchange and Anxiety Spread in the Early Stage of the Novel Coronavirus (COVID-19) Outbreak in South Korea: Structural Topic Model and Network Analysis
Authors: Jo Wonkwang , Lee Jaeho , Park Junli , Kim Yeol 
Published: May 2020

Background
In case of a population-wide infectious disease outbreak, such as the novel coronavirus disease (COVID-19), people’s online activities could significantly affect public concerns and health behaviors due to difficulty in accessing credible information from reliable sources, which in turn causes people to seek necessary information on the web. Therefore, measuring and analyzing online health communication and public sentiment is essential for establishing effective and efficient disease control policies, especially in the early stage of an outbreak.

Objective
This study aimed to investigate the trends of online health communication, analyze the focus of people’s anxiety in the early stages of COVID-19, and evaluate the appropriateness of online information.

Methods
We collected 13,148 questions and 29,040 answers related to COVID-19 from Naver, the most popular Korean web portal (January 20, 2020, to March 2, 2020). Three main methods were used in this study: (1) the structural topic model was used to examine the topics in the online questions; (2) word network analysis was conducted to analyze the focus of people’s anxiety and worry in the questions; and (3) two medical doctors assessed the appropriateness of the answers to the questions, which were primarily related to people’s anxiety.

Results
A total of 50 topics and 6 cohesive topic communities were identified from the questions. Among them, topic community 4 (suspecting COVID-19 infection after developing a particular symptom) accounted for the largest portion of the questions. As the number of confirmed patients increased, the proportion of topics belonging to topic community 4 also increased. Additionally, the prolonged situation led to a slight increase in the proportion of topics related to job issues. People’s anxieties and worries were closely related with physical symptoms and self-protection methods. Although relatively appropriate to suspect physical symptoms, a high proportion of answers related to self-protection methods were assessed as misinformation or advertisements.

Conclusions
Search activity for online information regarding the COVID-19 outbreak has been active. Many of the online questions were related to people’s anxieties and worries. A considerable portion of corresponding answers had false information or were advertisements. The study results could contribute reference information to various countries that need to monitor public anxiety and provide appropriate information in the early stage of an infectious disease outbreak, including COVID-19. Our research also contributes to developing methods for measuring public opinion and sentiment in an epidemic situation based on natural language data on the internet.
Direitos Fundamentais e Direitos Humanos: o estreitamento das fronteiras conceituais e a necessidade de um diálogo entre a órbita jurídica interna e internacional
Authors: Sampaio Rossi Amélia 
Published: May 2020

Os Direitos Humanos Fundamentais são, atualmente, o cerne dos sistemas jurídicos democrático-constitucionais e do discurso jurídico, político e social utilizados em resoluções de conflitos domésticos ou internacionais. A pessoa humana é um valor que deve ser protegido pela ordem jurídica interna de Estados nacionais, mas também um valor que merece especial proteção jurídica no âmbito internacional. Assim, neste trabalho, realizado por meio de pesquisa bibliográfica e documental, que utilizou o método histórico-dialético, afirma-se que a diferença das expressões “direitos humanos” e “direitos fundamentais” não subsiste. Elas são inúteis para expressar a delimitação espaço-territorial e injustificáveis no contexto de mundo globalizado e na perspectiva de um constitucionalismo plural.
Segurança e justiça: o acordo de não persecução penal e sua compatibilidade com o sistema acusatório
Authors: Langroiva Pereira Claudio José , Girade Parise Bruno 
Published: May 2020

A segurança pública envolve diretamente a segurança jurídica e a segurança das instituições democráticas. A partir do reconhecimento pelo Supremo Tribunal Federal brasileiro da constitucionalidade de investigações penais serem realizadas diretamente pelo Ministério Público, sem a presidência da autoridade policial, o Conselho Nacional do Ministério Público cumpriu determinação de regulamentar a questão, em âmbito institucional, quando editou a Resolução 181, de 7 de agosto de 2017. Além da regulamentação da investigação, a Resolução também prevê em seu artigo 18 o “acordo de não persecução penal”.
Diante desse cenário, o artigo tem como objetivo geral avaliar a Resolução e o referido instituto. Para isso, toma como premissas a Constituição Federal brasileira, o sistema acusatório, os princípios da legalidade e da reserva legal.
Como objetivo específico, o texto pretende analisá-los sob a ótica do devido processo legal (penal) e dos direitos e garantias fundamentais do cidadão no Estado Democrático de Direito brasileiro. A questão que impulsiona a investigação, ligada diretamente à segurança jurídica e à segurança das instituições democráticas, está em saber se ao propor uma modificação no Processo Penal por meio de Resolução, com acordos realizados antes da denúncia e com contrapartidas assemelhadas à pena, o órgão ministerial obedeceu ao sistema processual vigente.O estudo utiliza como método, predominantemente, a revisão bibliográfica e procura traçar um diálogo entre autores contemporâneos sobre o tema em questão.

Recomendamos analizar las estrategias aplicadas en menos del 70% para identificar su pertinencia.
Studies on the Need to Monitor IAQ Indicators in the Production Hall with Microclimate with Heat Release - Study on Companies from Mures County
Authors: Bucur Mihaela 
Published: May 2020

Abstract
Hundreds of millions of people around the world spend almost a third of their day at work. Many of them are dissatisfied with the climatic conditions in which they work, being exposed to various risks of heat or cold. The most common reasons for dissatisfaction are elements related to IAQ (Indoor Air Quality), in other words, thermal comfort and air quality inside the buildings. Thus, the assessment of the microclimate in the workplace is very important, and the IAQ indicators play a decisive role in the mental and physical capabilities. This writting wants to identify for the area of Mures county how many of the managers of the production halls with microclimate with heat release, where the workers are exposed to stress because of the heat, are aware of these elements and give them the proper importance.
The L-moment based regional approach to curve numbers for Slovak and Polish Carpathian catchments
Authors: Kohnová Silvia , Rutkowska Agnieszka , Banasik Kazimierz , Hlavčová Kamila 
Published: May 2020

Abstract
The main objective of the paper was to propose and evaluate the performance of a regional approach to estimate CN values and to test the impact of different initial abstraction ratios. The curve number (CN) was analyzed for five Slovak and five Polish catchments situated in the Carpathian Mountains. The L-moment based method of Hosking and Wallis and the ANOVA test were combined to delineate the area in two homogenous regions of catchments with similar CN values. The optimization condition enabled the choice of the initial abstraction ratio, which provided the smallest discrepancy between the tabulated and estimated CNs and the antecedent runoff conditions. The homogeneity in the CN within the regions of four Slovak and four Polish catchments was revealed. Finally, the regional CN was proposed to be at the 50% quantile of the regional theoretical distribution function estimated from all the CNs in the region.
The approach is applied in a group of Slovak and Polish catchments with physiographic conditions representative for the Carpathian region. The main benefit of introducing a common regional CN is the opportunity to apply this procedure in catchments of similar soil-physiographic characteristics and to verify the existing tabulated CN. The paper could give rise to an alternative way of estimating the CN values in forested catchments and catchments with a lack of data or without observations.
Analysis of changes in hydrological cycle of a pristine mountain catchment. 2. Isotopic data, trend and attribution analyses
Authors: Holko Ladislav , Danko Michal , Sleziak Patrik 
Published: May 2020

Abstract
δ18O in precipitation at station Liptovský Mikuláš (about 8.5 km south from the outlet of the Jalovecký Creek catchment) remains constantly higher since 2014 that might be related to greater evaporation in the region of origin of the air masses bringing precipitation to the studied part of central Europe. Increased δ18O values are reflected also in the Jalovecký Creek catchment runoff. Seasonality of δ18O in the Jalovecký Creek became less pronounced since 2014. The most significant trends found in annual hydrological data series from the catchment in the study period 1989–2018 have the correlation coefficients 0.4 to 0.7. These trends are found in the number of flow reversals (change from increasing to decreasing discharge and vice versa), June low flow, number of simple runoff events in summer months (June to September) and the flashiness index. The attribution analysis suggests that drivers responsible for the changes in these data series include the number of periods with precipitation six and more days long, total precipitation amount in February to June, number of days with precipitation in June to September and total precipitation in May on days with daily totals 10 mm and more, respectively. The coefficients of determination show that linear regressions between the drivers and supposedly changed data series explain only about 31% to 36% of the variability. Most of the change points detected in the time series by the Wild Binary Segmentation method occur in the second and third decades of the study period. Both hydrometric and isotopic data indicate that hydrological cycle in the catchment after 2014 became different than before.

Published: May 2020

Abstract
The overall study objection is selection and optimization all available thermodynamic data required for using calculation of phase diagram (CALPHAD) technique within the Fe-C-Cr-Mn-Si-Ti system. Such data collected in the thermodynamic database can be used for predicting the phase constitution states of a given composition for Fe-based hardfacing materials, which often use in energy industry in order to increase the abrasion and impact wear resistance of equipment parts. In order to compare theroretical calculation results with experimental data, four different types of hardfacing were deposited using flux-cored arc welding. Microstructure and chemical composition of deposited layers was investigated using optical and scanning electron microscopy together with energy dispersive X-ray spectroscopy. Comparison of experimental and computed results shows that they are in good agreement in meaning of presence of all-important phase equilibrium regions. The developed database can be used for rational selection of hardfacing materials for energy industry equipment and reasonable choice of new alloying systems.

Authors: Bijańska Jolanta , Wodarski Krzysztof 
Published: May 2020

Abstract
The primary objective of this paper is to present a model of a process management system developed to support the restructuring of Polish enterprises of the hard coal mining industry. The development of this model required research in three stages using several research methods. The stage I of the research was oriented towards the recognition of the existing state of knowledge in the scope of previously developed models of process management in enterprises. At this stage, a method of reviewing the literature, the analysis and synthesis of the results of considerations, was used. The stage II was oriented towards presenting of the current state of knowledge in the field of process management to the managerial staff of mines in order to identify their needs, capabilities and preferences. The research were attended by 24 managers from PGG SA and JSW SA. At this stage, the method of targeted free-form interview and discussions, was used. The stage III of the research was oriented towards the development of a process management system model in enterprises operating in the hard coal mining industry, based on the scientific achievements to date in the field of process management and consensus on the needs, preferences and capabilities of mine managerial staff with regard to its specific elements. At this stage, the method of analysis and synthesis was used. The results of the research presented in this publication are primarily addressed to the managerial staff of polish hard mines, as they provide a synthesized response to the problem of the lack of consistent process management guidelines that could set a standard within a mining enterprise. The model presented in the publication is of a general nature, although it may provide a basis for the application of process management for mines.

Authors: Hanzel Jurij , Kosir Bozic Tajda , Stabuc Borut , Jansa Rado 
Published: May 2020

Abstract

Background
Sorafenib is an oral multi-kinase inhibitor used for the treatment of hepatocellular carcinoma. Its efficacy in randomised controlled trials was demonstrated in patients with well-preserved liver function and good functional status. In the real-world setting, treatment is often offered to patients outside these criteria. We therefore performed a single-centre real-world cohort study on the efficacy of sorafenib in patients with hepatocellular carcinoma.

Patients and methods
We identified all patients with hepatocellular carcinoma initiating treatment with sorafenib between January 2015 and January 2018. The primary endpoint was overall survival (OS) since starting sorafenib. Clinical and demographic variables associated with survival were studied.

Results
The median OS was 13.4 months (95% CI 8.2–18.6). Multivariable Cox’s regression identified worse ECOG performance status (HR 2.21; 95% CI 1.56–3.16; P < 0.0001), Child-Pugh class C (HR 52.4; 95% CI 3.20–859; P = 0.005) and absence of prior locoregional treatment (HR 2.30; 95% CI 1.37–3.86; P = 0.002) to be associated with increased mortality.

Conclusions
Careful selection of patients for treatment with sorafenib is of paramount importance to optimize outcomes.

Abstract

Background
According to the current pathological classification, lung adenocarcinoma includes histological subtypes with significantly different prognoses, which may require specific surgical approaches. The aim of the study was to assess the role of CT and PET parameters in stratifying patients with stage I adenocarcinoma according to prognosis.

Patients and methods
Fifty-eight patients with pathological stage I lung adenocarcinoma who underwent surgical treatment were retrospectively reviewed. Adenocarcinoma in situ and minimally-invasive adenocarcinoma were grouped as non-invasive adenocarcinoma. Other histotypes were referred as invasive adenocarcinoma. CT scan assessed parameters were: ground glass opacity (GGO) ratio, tumour disappearance rate (TDR) and consolidation diameter. The prognostic role of the following PET parameters was also assessed: standardized uptake value (SUV) max, SUVindex (SUVmax to liver SUVratio), metabolic tumour volume (MTV), total lesion glycolysis (TLG).

Results
Seven patients had a non-invasive adenocarcinoma and 51 an invasive adenocarcinoma. Five-year disease-free survival (DFS) and cancer-specific survival (CSS) for non-invasive and invasive adenocarcinoma were 100% and 100%, 70% and 91%, respectively. Univariate analysis showed a significant difference in SUVmax, SUVindex, GGO ratio and TDR ratio values between non-invasive and invasive adenocarcinoma groups. Optimal SUVmax, SUVindex, GGO ratio and TDR cut-off ratios to predict invasive tumours were 2.6, 0.9, 40% and 56%, respectively. TLG, SUVmax, SUVindex significantly correlated with cancer specific survival.

Conclusions
CT and PET scan parameters may differentiate between non-invasive and invasive stage I adenocarcinomas. If these data are confirmed in larger series, surgical strategy may be selected on the basis of preoperative imaging.
Ecclesiological Tendencies in the Ecumenical Approach of the Council of Crete
Authors: Crișan Alexandru-Marius 
Published: May 2020

Abstract
The Ecumenical legacy of the Council of Crete convened in 2016 is extremely important because of the consistent discussions on this topic during the grounding of the Council, but mostly subsequent to that, when the process of reception of the Council began. The Holy and Great Council of Crete of 2016, known also as the Pan-Orthodox Council, issued six official documents plus a Message and an Encyclical. Among those documents, one is dedicated to the question of ecumenical relations. Inside various Orthodox Autocephalous Churches different groups denounced the Council because of its ecumenical approach, meaning that a good understanding of the ecumenical legacy of the Council of Crete is one of the most important keys in its reception. In this study I will try to inspect the ecclesiological theology found in the Document on Ecumenical Relations released in 2016 by the Council of Crete, thereby analyzing why some of the groups rejected this document. Comparing different forms of the documents with the final approved form will help us understand how the Orthodox approach to ecumenism evolved in time, since the beginning of the preparations for the Holy and Great Council of the Orthodox Church.
Does Stress Lead to Creativity?: The Relationship Between Occupational Stress and Individual Innovative Behavior
Authors: Luis Daniel Jose , Ruth Chatelain-Jardon , Zhuofan Zhang 
Published: May 2020

Abstract
Individual innovative behavior can have important implications for organizations. This article studies the relationship between occupational stress and individual innovative behavior. Data from 139 subjects from the US was analyzed using structural equation modeling as the technique. Results from partial least squares show that there is a positive and significant relationship between both constructs. Moreover, both variables present a U form relationship. Based on this research, it could be concluded that occupational stress could influence positively innovative behavior at work. Practical implications suggest that innovative behavior could be boost by identifying conditions at work that could produce time pressure. Elements such as work overload, feedback and allowing employees to take risks could help in idea generation.
