The popularity of social media has led to a variety of communicative behaviors among users. This study targeted Facebook as a representative social medial platform because it has the most subscribers in order to investigate factors that influence Facebook usage. In particular, because a person's behavior is based on how they are perceived by others, self-conscious behavior was examined in the study. Facebook usage and news consumption were examined to ascertain the effects of self-consciousness. An online survey was conducted to examine how private SC and public SC (SCs), affects Facebook usage (profiles and writing posts) and news consumption (clicking "like" and sharing news). 616 participants completed the survey, and results indicated that public SC was positively related to the degree of profile updating and post writing. On the other hand, private SC was positively related to the degree of news sharing. These results suggest that psychological elements significantly predict a user's behavior on Facebook.

Background: Stomach cancer (SC) is the second leading cause of cancer death with the rate of 10.4% in the world. The correlation between the incidence and mortality rates of SC and human development index (HDI) has not been globally determined. Therefore, this study aimed to determine the association between the incidence and mortality rates of SC and HDI in various regions. Materials and Methods: In this global ecological study, we used the data about the incidence and mortality rate of SC and HDI from the global cancer project and the United Nations Development Programme database, respectively. Results: In 2012, SCs were estimated to have affected a total of 951,594 individuals (crude rate: 13.5 per 100,000 individuals) with a male/female ratio of 1.97, and caused 723,073 deaths worldwide (crude rate: 10.2 per 100,000 individuals). There was a positive correlation between the HDI and both incidence (r=0.28, P<0.05) and mortality rates of SC (r=0.13, P = 0.1) in the world in 2012. Conclusions: The high incidence and mortality rates of SC in countries with high and very high HDI is remarkable which should be the top priority of interventions for global health policymakers. In addition, health programs should be provided to reduce the burden of this disease in the regions with high incidence and mortality rates of SC.

Purpose: This paper systematically reviewed the effects of smoking cessation (SC) intervention among female smokers. Methods: A systematic search was performed targeting articles published on eight electronic databases, from January 1, 2010, to February 25, 2020. Nine studies were included in the systematic review. The risk of bias (RoB) tool was used to evaluate the quality of scientific evidence. Results: A randomized controlled trial (RCT) was performed in all nine studies. Interventions were classified as exercise (n=4), cognitive behavioral counseling (n=2), motivational counseling (n=1), group counseling with self-help group (n=1), and pharmacotherapy (n=1). The SC rates were measured using a 7-days point prevalence abstinence in 55.6% of the studies. Exercise studies showed higher SC rates in the experimental groups than control groups after the intervention, but the differences were not significant. Other interventions were employed in two or fewer studies or did not conduct long-term follow-up, thus we were unable to examine effects of these interventions. Conclusion: It is necessary to develop SC programs for female smokers by carefully considering the characteristics of female smokers. Further research will be needed to confirm the effects of SC programs in certain subgroups among females. Also more experimental studies on SC intervention should be carried out with scientific rigor.

With developments in science and technology and improvement in living standards, human life expectancy is steadily increasing worldwide. For effective healthcare, it is necessary to check health conditions according to individuals' behavior and acquire prior knowledge on possible diseases. In this study, we classified the diseases that are major causes of death in Korea by referring to data provided by the Korea National Health and Nutrition Examination Survey. We selected indexes that could be used as indicators of major diseases and created the LCBB-SC. In the LCBB-SC, the data are systematically subdivided into related fields to provide integrated data related to each disease and to provide an infrastructure that can be used by researchers. In addition, by developing a web interface allowing for self-symptom assessments, this resource will be beneficial to people who want to check their own health condition using a list of diseases that might be caused by their behaviors.

본 연구의 목적은 기존 자동심장충격기인 T-AED와 새롭게 개발된 SC-AED의 제세동 신속성 및 사용자가 느끼는 주관적 편의성을 비교하는 것이다. 2017년 2월부터 2018년 4월까지 전남지역의 D대학, C대학병원의 기본인명소생술 교육센터에서 의료종사자 및 일반인을 위한 기본소생술과정에 참여한 156명을 T-AED (n = 77) 및 SC-AED (n = 79) 그룹에 무작위할당 하였다. 각 그룹은 제세동을 실시한 후, 총 제세동 지연시간, 제세동 지연시간, 쇼크버튼 누름 지연시간, 후속 흉부압박 재개시간까지의 시간을 측정하였고 이를 t-검정을 통해 분석했다. 실험 후 조작자신감, 사용편의성, 의사결정 도움, 이상 3가지 요인에 대한 자료를 설문으로 수집하였고 각각 t-검정을 통해 분석하였다. SC-AED는 T-AED와 비교하여 총 제세동 지연시간(11.22 초), 제세동 지연시간(11.04 초) 및 쇼크버튼 누름지연시간(2.15 초)가 현저히 단축되었습니다 (p<0.001). 주관적 편의성 측면에서 자신감(T-AED : 7.62±1.25VAS vs. SC-AED : 7.80±0.98VAS, p = .358)는 중요하지 않았지만, 편의성(T-AED : 7.05±1.36VAS vs. SC) -AED : 8.95±0.89VAS, p<0.001) 및 의사결정도움(T-AED : 6.58 ± 1.73VAS vs. SC-AED : 9.08±0.98VAS, p = 0.001)은 유의한 차이를 보여주었다. 결론적으로 T-AED에 비해 의료종사자 및 일반인 집단 모두에서 더욱 신속한 제세동을 가능하게 하였으며, 사용자의 편의성과 명확한 의사결정을 크게 도와주었다. SC-AED에 적용된 기술이 향후 보편적인 자동심장충격기에 상용화된다면 더욱 효과적인 PAD를 통해 심정지 환자의 생존율 제고에도 이바지할 것이다.

A vegetative filter strip (VFS) is one of the best management practices (BMPs) to reduce pollutant loads. This study aims to assess the effectiveness of VFS in dense upland field areas. The study areas are agricultural fields in the Maedae (MD), Gaa (GA), and Jaun (JU) watersheds, where severe sediment yields have occurred and the Korean government has designated them as non-point management regions. The agricultural fields were divided into three or four clusters for each watershed based on their slope, slope length, and area (e.g., MD1, MD2). To assess the sediment trapping (STE) and pesticide reduction efficiency (PRE) of VFS, the Vegetative Filter Strip Modeling System (VFSMOD) was applied with three different scenarios (SC) (SC1: VFS with rye vegetation; SC2: VFS with rye vegetation and a gentle slope in VFS range; and SC3: VFS with grass mixture). For SC1, there were relatively short slope lengths and small areas in the MD1 and GA3 clusters, and they showed higher pollutant reduction (STE>50%, PRE>25%). For SC2 and SC3, all clusters in GA and some clusters (MD1 and MD3) in MD show higher pollutant reduction (>25%), while the uplands in JU still show a lower pollutant (<25%). With correlation analysis between geographic characteristics and VFS effectiveness slope and slope length showed relative higher correlations with the pollutant efficiency than a area. The results of this study implied that slope and slope length should be considered to find suitable upland conditions for VFS installations.

Objective: The purpose of this study was to identify and compare social capital measurement tools for the convenient use in public health studies. Method and result: This study examined and compared social capital tools developed individually by the World Bank, the OECD, the United States, United Kingdom, Canada, Australia, Ireland, and Korea. A comprehensive framework was constructed with six conceptual dimensions and sixteen indices. The six dimensions included Membership, Network, Trust, Information and communication, Social and civic participation, and Social cohesion and exclusion, which connoted the structural, cognitive, bonding, bridging, operative, and output elements. The indices of each tool were respectively matched to the indices of the comprehensive framework. The comprehensive tools were Integrated Questionnaire for the Measurement of Social Capital (SC-IQ) of the World Bank with 27 questions and the European Social Survey (ESS) of the OECD with 80 questions. Conclusion: The SC-IQ should be utilized in public health studies due to its simplicity yet comprehensiveness as a social capital tool. The ESS should also be considered as a comprehensive tool.

With the increased number of single-cell RNA sequencing (scRNA-seq) datasets in public repositories, integrative analysis of multiple scRNA-seq datasets has become commonplace. Batch effects among different datasets are inevitable because of differences in cell isolation and handling protocols, library preparation technology, and sequencing platforms. To remove these batch effects for effective integration of multiple scRNA-seq datasets, a number of methodologies have been developed based on diverse concepts and approaches. These methods have proven useful for examining whether cellular features, such as cell subpopulations and marker genes, identified from a certain dataset, are consistently present, or whether their condition-dependent variations, such as increases in cell subpopulations in particular disease-related conditions, are consistently observed in different datasets generated under similar or distinct conditions. In this review, we summarize the concepts and approaches of the integration methods and their pros and cons as has been reported in previous literature.

Objectives: The purpose of this study was to investigate safety consciousness (SC), cognitive-behavioral strategy (CBS), and safety behavior (SB) among university students living in dormitories on campus. Methods: The data was analyzed to compare the safety behavior by sex, safety related factors, and safety consciousness index in the SPSS 23 program using Chi-square test, t-test, Pearson correlation coefficients, and multiple regression. Results: The participants in the health and safety behaviors survey were 2,721 students who have been in dormitories on campus. On the mean of items, the Public Safety Consciousness Index (PSCI) was 93.1, SC was 26.9, CBS was 15.7, and SB was 50.4. It were significant correlations between SC, CBS, and SB among university students (r=0.74-0.78), and CBS was identified as the mediator. Finally, it was significant increase the SC, CBS, and SB by sex and participation on safety education, but decrease by age and experience of accident and disaster. Conclusions: It is necessary to develop safety education program enhancing safety consciousness and safety behavior in order to prevent accidents on campus. And it suggests that safety education should be included in regular curriculum of university to improve health status and achieve academic goals.
