Objectives：Body image is closely related to self-esteem and weight-control related behaviors. In particular, relationship between two factors would be stronger in female adolescents. False recognition on body image and weight can be a risk factor of eating disorder, depression, and suicidal ideation. This study aimed to examine the effects of body image and eating disorders on developing depressive symptoms and suicidal ideation in female adolescents. Methods：Two hundred thirty nine students of a Girls' Commercial High School in Seoul were recruited. Eating Attitude Test for Korean Adolescents, Self-Esteem Scales, Impulsiveness Scale, Beck's Depression Inventory and Beck's Suicidal Ideation Scale were used to measure eating attitude and severity of psychiatric symptoms. Results：Among 239 subjects, the estimated risk group of eating disorders was 10%(n=24). They experienced more depressive symptoms than the control group. The bigger discrepancy in current and ideal body mass index was significantly related with higher depressive mood, suicidal idea, abnormal eating habits and lower self-esteem. Discrepancy between current and idea BMI was the most meaningful predictive factor about depression and suicidal thoughts by linear regression analysis. Conclusion：In spite of normal weight range of enrolled subjects, they experienced significant depressive mood, suicide thoughts and lower self-esteem associated with the discrepancy of their own subjective body image and current body mass index. Hence educational approach regarding normal body image and healthy weight control is needed for their mental health and preventing eating disorder.

Using survey data of selected 1,349 individuals nationwide in Korea, we measure the influencing factors for the acceptance of nuclear power and estimates the probability of acceptance under several scenarios with different percentages of monetary compensation. Results of panel probit demonstrate that nuclear risk aversion tendency was found to be higher in case of female, younger age, past experience of extreme event such as an earthquake. However, the residents' residency nearby the nuclear power plant was not related to the risk-aversion tendency. In addition, we found that the nuclear acceptance is improved when the monetary compensation rate is increased. Although the policy demand intended to reduce GHG emissions in South Korea, the expansion of nuclear power is not be easy due to the occurrence of recent strong earthquakes because the risk attitude of an individual is influenced by subjective assessments formed through direct and indirect experiences of natural disasters such as an earthquake. Our results suggest that the opposition to construction of nuclear power plant is expected to be further intensified especially when combined with the experiences of threatening earthquakes. As a result, the debate and policy conflicts of nuclear power plants will consistently continue and large social costs are apparent for the acceptance of nuclear power plant.

This study examined the relationships among levels of knowledge, attitude and preventive behavior regarding tuberculosis in service workers. The survey period was 1 - 7 October, 2015 with service workers who work in large scale stores in Jeonnam. The collected data were analyzed using an independent t-test, ANOVA, and Pearson's correlation coefficients using the SPSS WIN 12.0 program. The mean score for knowledge about tuberculosis was $14.05{\pm}6.39$, the mean score of attitude toward tuberculosis was $29.87{\pm}4.89$ and the mean score of preventive behavior for tuberculosis was $31.44{\pm}4.86$. Preventive behavior was found to have significant relationships with gender, marital status, smoking, job satisfaction, and subjective health status. A slightly positive correlation was observed between the knowledge of tuberculosis and the attitudes toward tuberculosis. A positive correlation was noted between the attitude toward tuberculosis and preventive behavior for tuberculosis, while there was a negative correlation between the preventive behavior and age. Therefore, is necessary to consider the related factors for the development and implementation of systematic education programs that can encourage and promote preventive behavior for tuberculosis among service workers.

A survey of risk perception in Korea was conducted in 2001 with a special emphasis on industrial and technological risks. This article summarizes the characteristics of risk perception in consideration of socio-demographic background of respondents. The survey with sample size of 1,870 evaluates the perceived level of 25 risk items in the areas of transportation, chemicals, environment, industry, and nuclear power generation. Risks are categorized by using factor analysis to clarify attitudinal or behavioral properties of risk perception. Research findings show that the level of perceived risk does not correspond to the statistical level. Socio-demographic variables are significant predictors in explaining risk perception, or the discrepancies between "subjective" and "objective" risks. Effective risk communication can reduce the perceptional discrepancies, improve the awareness of technological risks, and ultimately facilitate the process of making and implementing policies for risk management and safety regulation. This article tries to provides policy guidelines for "Who is the target for risk communication" and "Which risk has the policy priority for safety improvement." Married females at the age of 30s and 40s with lower education and lower income in small cities are more vulnerable to risk misperception than other groups. More information and knowledge regarding unfamiliar, intangible, new technological risks should be delivered to the vulnerable groups for reducing perceptional bias. Society-wide safety can be improved by integrating policy, human, and social factors as well as techno-engineering advances.

The purpose of this study was to compare the health behaviors, mental health and internet addiction by gender differences among Korean adolescents and to examine relevances between health behaviors, mental health and internet addiction. The subjects were 73,238 Korean adolescents(male: 38,391, female: 34,847) who were recruited through national web-based survey. The data were derived from the Sixth Korea Youth Risk Behavior Web-based Survey 2010 in South Korea. There were significant differences in health behaviors, mental health and internet addiction. by gender differences. Prevalence of internet addiction was male: 3.9%, female: 1.9% in this study. As the result of multiple logistic regression, the risk of internet addiction was increased in the case of smoking experience, substance experience, subjective health status, feeling of stress, depression experience, suicidal ideation, feeling of happiness, and sufficiency of sleeps in both male and female. Therefore, to decrease internet addiction prevalence, it is necessary to detect and manage the influencing risk factors of internet addiction such as health behaviors and mental health. And the health-promotion intervention to improve the internet addiction of adolescents should be planed and provided considering such differences by gender differences.

Although tinnitus is a common disease, it's reason, pathogenesis and treatment are not examined clearly. As tinnitus is a subjective complaint, it is not easy to evaluate objectively and to compare with another. In this study, we intend to estimate the effect of a variety of oriental medical treatments to tinnitus. We inquired about 30cases of tinnitus patients visited the Kwang-ju Oriental Medical Hospital of Wonkwang University from Apr. 1998 to Sep. 1998. We examined the 30cases in the view of sex, age, occupation, duration, etiologic factors, past history, associating symptoms, quality of tinnitus, and recovery rate after treatments. The results were as follows: 1. In distribution of sex, the ratio of male was $63.3\%$(19cases)and\;female\;was\;36.6\%$(11cases). 2. In distribution of age, the ratio of the 2th decade was $6.6\%(2cases),\;the\;3th\;decade\;was\;20.0\%(6cases),\;the\;4th\;decade\;was\;16.6\%(5cases),\;the\;5th\;decade\;was\;23.3\%(7cases),\;the\;6th\;decade\;was\;30.0\%\;(9cases),and\;the\;7th\;decade\;was\;3.3\%(1case)$. 3. In distribution of occupation, the ratio of employee was $23.3\%$(7cases), house-keeper was $63.3\%(11cases),\;farmer\;was\;16.6\%(5cases),\;teacher\;was\;13.3\%$ (4cases), and student, merchant, soldier was each $3.3\%$(1case). 4. In distribution of duration, the ratio of under 1month was $6.6\%$ (2cases), 1 month -6 months was $20.0\%$(6cases), 6 months- 12months was $30.0\%$(9cases), 12months-36months was $23.3\%$(7cases), and over 36months was $20.0\%$(6cases). 5. In etiologic factor of tinnitus, the ratio of unknown reason was $40.0\%$ (12cases), overwork was $16.6\%$(5cases), emotional stress was $10.0\%$(3cases), noise was $6.6\%$(2cases), cases of laying overwork upon stress was $13.3\%$(4cases), head trauma was $3.3\%$(1case), gun report was $3.3\%$ (1case), and after sickness was $6.6\%$(2cases). 6. 9 cases had experienced such a disease as meniere's disease, tympanitis, labyrinthitis, trauma of tympanum, hypertension, etc. 7. Commonly associated symptoms were dizziness, deafness, uneasiness, headache, ear fullness, fatigue, insomnia, nausea, vomiting, and forgetfulness. 8. Most frequent quality of tinnitus were buzzing, whistling, humming etc. 9. In $76.6\%$(23cases) of tinnitus patients, it was improved, but in $23.3%$(7cases) of them, not improved.

In hydrologic models, parameters are mainly used to reflect hydrologic elements or to supplement the simplified models. In this process, the proper selection of the parameters in the model can reduce the uncertainty. Accordingly, this study attempted to quantify the uncertainty of SWAT parameters using the General Likelihood Uncertainty Estimation (GLUE). Uncertainty analysis on SWAT parameters was conducted by using the formal and informal likelihood measures. The Lognormal function and Nash-Sutcliffe Efficiency (NSE) were used for formal and informal likelihood, respectively. Subjective factors are included in the selection of the likelihood function and the threshold, but the behavioral models were created by selecting top 30% lognormal for formal likelihood and NSE above 0.5 for informal likelihood. Despite the subjectivity in the selection of the likelihood and the threshold, there was a small difference between the formal and informal likelihoods. In addition, among the SWAT parameters, ALPHA_BF which reflects baseflow characteristics is the most sensitive. Based on this study, if the range of SWAT model parameters satisfying a certain threshold for each watershed is classified, it is expected that users will have more practical or academic access to the SWAT model.

Career guidance refers to services intended to assist students to make educational and occupational choices and to manage their careers. Young students, specially enrolled in vocational high schools, need programs to help them make transitions to the working world and to re-engage with further learning, and career guidance needs to be part of such programs. Teachers assume the critical roles in planning and organizing the career guidance programs in vocational high schools. The program includes career information provision, assessment and self-assessment tools, career counseling, work search, etc. In this study, we developed a research model based upon TRA(theory of reasoned action) developed by Ajzen and Fishbein to investigate the factors influencing the intention to provide career guidance services to students in vocational high schools. Based on 155 survey responses from vocational high school teachers, we show that attitude and subjective norm motivate teachers to provide career guidance services, and that attitude toward career guidance is directly influenced by self-efficacy for career guidance and burden from extra work. It was also confirmed that facilitating condition is the antecedent of self-efficacy. But contrary to our expectation, self-efficacy for career guidance has no significant effect on the intention for providing career guidance services at 5% significance level. In light of these findings, implications for theory and practice are discussed.
