Korea worker is well known for its long work and amongst employees and to change un-healthy lifestyle. This study aims to investigate the association between health behaviors and sleep problems in employees. It employed data from the Third Korean Working Conditions Survey (KWCS). The total number of individuals included in the analysis was 34,788 employees, from the 2011 survey. The outcome was sleep problems, which had a prevalence rate of 2.5% in men and 2.3% in women. An adjusted odds ratios were as follows: 2.26(1.75-2.91) for hypertension, 2.21(1.60-3.06) for obesity, 26.82(21.51-33.45) for depression and 2.02(1.64-2.49) for high level of job stress. We need to invest to identify relevant and various health service promotion for sleep problem that un-healthy workers want will use.

To investigate the perception of the correlation between systemic diseases and oral health among some university students. The questionnaires were conducted on 485 students from 3 universities in Gwangju. As a result of the study, the female was higher than the male and was the highest in the fourth grade. Subjective health status, drinking status, smoking experience, and exercise were not significantly different in recognizing the association between systemic disease and oral health. The group with experience in oral health education recognized 3.18, and the group that practiced educational contents was highly recognized as 3.21. There was a significant difference between the two groups. Multiple regression analysis showed that major factor and grade factor influenced the perception of association between systemic disease and oral health. Therefore, it is necessary for university students to recognize the importance and necessity of periodical oral examinations. It is thought that the incidence of disease should be strengthened and enforced to recognize that there is a correlation with various diseases.

The purpose of this study was to analyze the effects of adolescents' Internet Usage Levels on their oral symptoms using the data from 60,040 students in the 14th Korea Youth Risk Behavior Web-Based Survey in 2018. The logistic regression for the effects of Internet Usage Level on the oral symptoms were analyzed using a logistic regression method. Symptoms of toothache when eating and throbbing symptoms, and gum pain symptoms showed high levels of stress, and high awareness of pain when lower daily frequency of tooth-brushing. In addition, the less time spent on the Internet, the more subjective health awareness, the higher sleep satisfaction, the less smoking and drinking experience, Results were significantly lower. In conclusion, health education that mitigates adolescents' excessive use of the Internet is believed to enable proper health practices and is intended to help develop health education programs that can prevent such oral symptoms.

This study aimed to compare general and female health-related factor between day-work and shift-work worker. It is based on the data of the Korea National Health&Nutrition Examination Survey(KNHANES) 2nd year on 7th period. The number of participants was 10,430. Out of the participants, 1,995 workers' dara was analyzed. The age, marital status, education level, occupational status and childbirth experience of female workers indicated significant differences between day and shift work. By contrast, health-related quality of life did not represent significant differences these factors; income, subjective health cognition, stress perception, depression experience, menarcheal age, menopausal age and breastfeeding period. The shift work is inevitably implemented as an industrial development and flexible work hours. Therefore, social and national attention and measures as well as those of individual workers are required to reduce the side effects from shiftwork.

This study was conducted to explore the determinants of happiness for Korean Old People. A total of 105 Korean old people responded to open-ended questions about their happiness. From the content analysis of those reponses were happiness-related 70 items derived. Then 200 old people rated themselves on the list of those items. Factor analysis of those data ended up with 33 items of 8 factors, which were ①Family relationship, ②Religion, ③Financial ability, ④Health, ⑤Work/Job, ⑥ Psychological stability, ⑦Leisure, ⑧Public welfare. This Happiness Scale for the Korean old people, Subjective wellbeing Scale, Emotion experience Scale, and Self-esteem Scale were also administered to the identical 200 Korean old people. Results indicated that the construct validity of this new Happiness Scale for Korean old people was obtained. Finally, the implications and limitations of the present study and suggestions for further studies were discussed.

The METRO-K is a model for a radiological dose assessment due to a radioactive contamination in the Korean urban environment. The model has been taken part in the Urban Remediation Working Group within the IAEA's (International Atomic Energy Agency) EMRAS (${\mathbf{\underline{E}}}nvironmental$ ${\mathbf{\underline{M}}}odeling$ for ${\mathbf{\underline{RA}}}diation$ ${\mathbf{\underline{S}}}afety$) program. The Working Croup designed for the intercomparison of radioactive contamination to be resulted from the explosion of a radiological dispersal device in a hypothetical city. This paper dealt intensively with a part among a lot of predictive results which had been performed in the EMRAS program. The predictive results of three different models (METRO-K, RESRAD-RDD, CPHR) were submitted to the Working Group. The gap of predictive results was due to the difference of mathemathical modeling approaches, parameter values, understanding of assessors. Even if final results (for example, dose rates from contamintaed surfaces which might affect to a receptor) are similar, the understanding on the contribution of contaminated surfaces showed a great difference. Judging from the authors, it is due to the lack of understanding and information on radioactive terrors as well as the social and cultural gaps which assessors have been experienced. Therefore, it can be known that the experience of assessors and their subjective judgements might be important factors to get reliable results. If the acquisition of a little additional information is possible, it was identified that the METRO-K might be a useful tool for decision support against contamination resulting from radioactive terrors by improving the existing model.

Recent development of 3D technologies made it possible that observers perceive 3D depth from two dimensional images. Despite this kind of technological development, when observers watch 3D display they experience 3D visual fatigue that they do not usually experience in real life. It is critical to measure visual fatigue in order to overcome the problem of 3D visual fatigue. The purpose of the present study was to develop a protocol to measure 3D visual fatigue based on an EEG signal and to examine its validity. The first experiment explored the possible ERP components that reflected visual fatigue in 2D and 3D conditions. The second experiment examined whether the feature of the component found in the first experiment was affected by the amount of binocular disparity. Both in Cz and Pz channels, the peak amplitude of P3 component was much lower in 3D rather than in 2D conditions, and it decreased as the amount of binocular disparity increased. The subjective 3D visual fatigue also increased with the amount of binocular disparity. These results imply that the peak amplitude of P3 component at Cz and Pz channels can be used as an index of 3D visual fatigue.

The purpose of this study was to find out the impact of psycho-social factors (social relationship and personal) as well as illness history and economic status on physical health and subjective well-being among the retired Koreans elderly. Data were collected from 1,315 elders (mean age = 72.70yrs) residing in Seoul and Chuncheon regional area via interviews(Time 1), and them were re-interviewed two year later(Time 2). Multiple regression analyses indicated that the retired elders' illness history, economic status, marital satisfaction, fulfillment of self-esteem need, drinking behavior, positive affectivity, negative affectivity and physical health to predict their subjective well-being at Time 1(R²=.705). The retired elders' economic status, marital satisfaction, positive affectivity, negative affectivity and physical health to predict their subjective well-being at Time 2(R²=.418). The retired elders' illness history, economic status, expectations for one's offspring, drinking behavior and subjective well-being to predict their physical health at Time 1(R²=.364). And the retired elders' illness history, economic status, marital satisfaction, positive affectivity and negative affectivity to predict their physical health at Time 2(R²=.265). In case of retired elderly, suggested for the psycho-social determenants of subjective well-being and physical health by occupational classification. The implications of this study and the suggestions for furture study were discussed.

This paper aims to identify determinants of entrepreneurial intentions among college students of a university in Daejeon. We have used a revised Entrepreneurial Intention Questionnaire including personal traits, demographic characteristics, the three factors of the Theory of Planned Behavior (TPB), motivations to startup and planned startup time, and entrepreneurial intentions. The analysis shows that there are strongly significant and positive relationships between the three TPB factors and entrepreneurial intentions of college students. In addition, students' motivations to create a firm such as independence and self-achievement have a positive and significant effect on their entrepreneurial intentions, while the students who want to start their business right after their graduation have significantly higher entrepreneurial intentions than those who want to create a firm after doing a salaried job. Furthermore, students whose parents have created or operated a firm have no significant difference from others, and parents' startup business type are significantly different from their sons and daughters' interested areas of business.
