Public acceptance is a major issue that will determine the future of nuclear energy. In this article, we review relevant studies and identify several common patterns of nuclear public acceptance. Based on these patterns and four categories of factors, we propose hypotheses on the impact of different socioeconomic factors on the public opinion of nuclear energy. These factors were demographic and social influences, politico-economic, energy conditions, and nuclear accidents and natural risks. We tested these hypotheses using a data set including survey results on public opinion of nuclear energy in 59 countries from 1987 to 2014. Results of the regression analysis generally verified the proposed hypotheses, especially regarding the positive impact of education or geological suitability and the negative effect of improved living standards and democracy on nuclear acceptance. We propose policy recommendations, including a better focus on education and communication and a thorough consideration of the social and geological conditions a country needs to make before deciding to go nuclear. Potential weaknesses of this study are also discussed, including the possible causal relation between independent variables and the binary nature of the dependent variable.

The principal objective of this study was to assess the current status of elementary students' intake of dietary supplements, in an effort to diagnose any overnutrition, and to employ the results as basic data for the establishment of a balanced nutritional education. A survey was conducted by using a questionnaire administered to 734 elementary students’ parents in Seoul, and the analyzed results were as follows: Most parents believed that their nutritional knowledge was better than the norm(91.5%). However, almost half of the parents(49.2%) were feeding certain dietary supplements to their children, despite their perception that their children were already healthy, and were not recognizing any significant beneficial effects from those supplements. The most popular dietary supplements being fed were vitamin complexes. The majority of children took at least one type of dietary supplements at a monthly cost of approximately 10,000${\sim}$30,000 won. These results revealed the potential for overnutrition in some of the elementary students as the result of dietary supplement intake; thus, further studies involving assessments of risk for dietary supplement overconsumption in children and proper dietary education for the parents are suggested.

Purpose: The purpose of this study was to investigate the relationship between clinical knowledge and provision of pressure ulcer care and to identify factors associated with performance of care. Methods: Participants were 202 nurses working in one of 6 small to medium hospitals. Self-report questionnaire were used and data were collected from December 11 to 18, 2009. Results: Mean score for knowledge about pressure ulcer care was 0.81. In subcategories, knowledge of risk factors inducing pressure ulcers was 0.93, knowledge of assessment of pressure ulcers was 0.90, and knowledge of treatment methods for pressure ulcers was 0.61. Mean score for performance of care activities for patients with pressure ulcers was 3.63/5. There was a significant positive correlation between knowledge and performance (r=.319, p<.001). According to multiple regression analysis, general perception (${\beta}=.306$, p<.001), knowledge (${\beta}=.247$, p<.001), and hospital size (${\beta}=.156$, p= .015) had an impact on the extent of nurses' performance of pressure ulcer care. Conclusion: Study results indicate that further education on pressure ulcer care is necessary to enhance nurses' knowledge about pressure ulcers and to increase rate of performance of pressure ulcer care.

The incidence of vivax malaria in Korea was reduced to a low plateau. For successful elimination of vivax malaria, socio-behavioral changes in the communities are essential. This study aimed to figure out awareness of the inhabitants on the vivax malaria endemicity. The 407 participants including vivax malaria patients and uninfected inhabitants in Gimpo- and Paju-si, Gyeonggi-do, known as high-risk areas in Korea. We used a community-based study design and non-probability sampling method using primary data. Except for the perception about the public health facilities' capability to cope with anti-malaria programs, the 2 groups of participants shared the same level of awareness about public promotional and educational measures and opinions for malaria elimination from the community. Thus, our future goals for malaria prevention and elimination are to develop more active and well-organized community-based education and evaluation programs collaborating with the community healthcare authorities and local governments.

Many bridges in Algeria were constructed without taking into account the seismic effect in the design. The implantation of a new regulation code RPOA-2008 requires a higher reinforcement ratio than with the seismic coefficient method, which is a common feature of the existing bridges. For better perception of the performance bridge piers and evaluation of the risk assessment of existing bridges, fragility analysis is an interesting tool to assess the vulnerability study of these structures. This paper presents a comparative performance of bridge piers designed with the seismic coefficient method and the new RPOA-2008. The performances of the designed bridge piers are assessed using thirty ground motion records and incremental dynamic analysis. Fragility curves for the bridge piers are plotted using probabilistic seismic demand model to perform the seismic vulnerability analysis. The impact of changing the reinforcement strength on the seismic behavior of the designed bridge piers is checked by fragility analysis. The fragility results reveal that the probability of damage with the RPOA-2008 is less and perform well comparing to the conventional design pier.

Although there have been lots of studies about users' behaviors online, few have explored the mechanism of hostile behaviors. In this sense, this study aims at discovering what may elevate users' hostile behaviors. More specifically, we tried to find the relationship between flaming behavior and perception factors such as perceived risk, anonymity and expected emotional reaction. A survey was conducted to investigate the relationship of the above variables. As a result, all these variables show significant effects on flaming, and information overload are found to act as a moderator. We carefully conclude that flaming in online community can be reduced by preventing information overload each user perceives.

Objectives: The purpose of this study was to examine whether demographic and socio-economic characteristics, health behaviors are related overweight and obesity in Korean adolescents. Methods: Data from the 15^th Korea Youth Risk Behaviors web-based Survey(KYRBWS) administered in 2019 were analyzed: 60,100 students in middle and high school participated in the survey. But except 1,555 missing value, 55,748 students were analyzed. It was conducted frequency analysis, Rao-Scott chi-square test and multiple logistic regression analysis. Results: The significant influencing factors on overweight and obesity of adolescents were gender, economic status, father's educational background, alcohol experience, fastfood consumption, muscle strengthening exercise, stress perception(p<.001). The odds ratio for overweight and obesity of male adolescents compared to female adolescents were 1.19(p<.001). and The odds ratio for overweight and obesity of perceived stress adolescents compared to those who without stress were 1.13(p<.001). Conclusions: I found that adolescents' some undesirable health behaviors affect their overweight and obesity, I recommend that school health promotion programmes should be implemented in schools to form good health behaviors such as healthy eating habits, physical exercise and managing stress.

This study is to examine the perception and difference of existing market participants on the intention of accepting domestic cargo transportation platform and analyze the effect of the intention on acceptance using UTAUT. Through the analysis, we can quantitatively examine the expectation of the cargo transportation platform expected by the participants in the transportation market and suggest implications. As the results of the analysis of variance conducted to understand the difference according to the variables of each industry, it was found that there was no difference in attitude according to the cargo transportation platform for workers of various companies such as transportation, distribution, and manufacturing. The results of the test showed that performance expectation, effort expectation, significance influence, and social impact had a positive (+) effect on acceptance intention. However, the hypothesis that perceived risk would have negative (-) effects on acceptance intention was not significant and was rejected.

Demand for air travel, which shrank sharply following the outbreak of the COVID-19, has recently recovered up to 80% before the spreading pandemic. As a result, the number of passengers are rapidly increasing again. However, financial difficulties and lack of skilled workers in the aftermath of a long-term recession and pandemic lead to a decrease in aviation safety awareness which is fundamental for safety culture. Consequently, this hazard can act as a potential risk factor for the global aviation industry preparing for a new leap forward in the post-pandemic era. Therefore, this study analyzed and defined the four key elements of aviation safety awareness; attitude, belief, perception, and value. Based on this analysis, this study combined the four key elements into the P-D-C-A cycle to derive what top management, middle managers, and workers should each do to continuously improve the positive safety culture.

Climate change is a constant threat to human life, and it is important to understand the public perception of this issue. Previous studies examining climate change have been based on limited survey data. In this study, the authors used big data such as news articles and social media data, within which the authors selected specific keywords related to climate change. Using these natural language data, topic modeling was performed for discourse analysis regarding climate change based on various topics. In addition, before applying topic modeling, sentiment analysis was adjusted to discover the differences between discourses on climate change. Through this approach, discourses of positive and negative tendencies were classified. As a result, it was possible to identify the tendency of each document by extracting key words for the classified discourse. This study aims to prove that topic modeling is a useful methodology for exploring discourse on platforms with big data. Moreover, the reliability of the study was increased by performing topic modeling in consideration of objective indicators (i.e., coherence score, perplexity). Theoretically, based on the social amplification of risk framework (SARF), this study demonstrates that the diffusion of the agenda of climate change in public news media leads to personal anxiety and fear on social media.
