Data were collected by self-administered questionnaires at middle and high school students located in Seoul and the metropolitan areas. Methods: The response rate is 94.8% (474 cases). The internet addition was measured by K Scale. The various methods of analysis were used, for example, frequency analysis, t-test, analysis of variance, and multiple regression analysis. Results: First, the mean score of internet addiction level is 2.07 in 5 Likert scale. the internet addiction level of the male students are higher than female students (p<.05). Second, as a result of classification of internet addiction groups by K Scale, 11 students (2.3%) are included in high risk group, 27 students (5.7%) are in potential risk group, 436 students (92.0%) are in general group. Third, the level of social support and self-efficacy of middle and high school students are very high. The difference of social support by internet addiction groups was not statistically significant. But, the difference of self-efficacy by internet addiction groups was statistically significant. The level of self-efficacy of the students in general groups are more higher than in high risk group and in potential risk group (p<.01). Fourth, the difference of school adjustment by internet addiction groups was very statistically significant. The level of school life adjustment of the students in general groups are more higher than in high risk group and in potential risk group (p<.01). Fifth, the internet addiction have a negative correlation with school life adjustment. And the social support and self-efficacy have a positive correlation with school life adjustment (p<.01). Finally, in stepwise multiple regression analysis, the internet addiction affects negatively on the school adjustment. And the support of teacher among three types of them affects positively on the school life adjustment. And the social self-efficacy among two types of them affects positively on the school adjustment (p<.01). Conclusion: to adjust desirably the school environment of the middle and high school students, optimal and efficient management of internet addiction was needed in the future and the improvement and promotion of social support and social self-efficacy of the students was also demanded.

This study was conducted to provide basic information on the nutritional status and dietary behaviors of the deaf teenagers. The subjects of this study were 87 deaf-mute high school students in Pusan and Kyung-nam area and, in comparison,90 general high school students in Ham-an area. The survey was investigated by using a self-administered questionnaire. The results were as follows: Deaf-mute group was consisted of 63.2% male and 36.8% female, and mean of height and weight of male were 171.2 cm and 61.9kg, female were 158.0cm and 51.7kg. Obesity index and body mass index (BMI) were normal range in both deaf-mute and normal groups. The average nutrition knowledge score of the deaf-mute group was 6.8 $\pm$ 1.5 out of possible 10 points, that was significantly lower than 7.3 $\pm$ 0.8 of the normal group (p<0.01). The mean of self-control and conscious control scores in the eating behaviors of the deaf-mute group were 2.6 $\pm$ 1.2 and 2.4 $\pm$ 1.3 out of possible 5 points from each item, which was significantly higher than 2.1 $\pm$ 1.3 and 1.8 $\pm$ 1.4 of the normal group (p< 0,01). Nutrients consumed below 90% of Korean RDA were energy (79.9%), Ca (71.5%) for deaf-mute male students and Ca (88.5%) for deaf-mute female students. Energy (71.4%), protein (87.8%), Ca (74.8%), vitamin B$_1$ (83.4%) intake of normal male students and energy (72.8%), Ca (71.2%), Fe (78.7%) intake of normal female students were below 90% of Korean RDA. Energy, protein, fat, vitamin B$_1$, niacin intake of deaf-mute male students were significantly higher than normal male students and all nutrients intake of deaf-mute female students were significantly higher than normal female students. By the correlation of nutrients intakes with nutrition knowledge, there was positive correlation with the intakes of Ca, Fe, vitamin A, vitamin B$_2$, and vitamin C in the deaf-mute group, while there was negative correlation with the nutrients intakes (except for protein and fat) in the normal group. The amount of meal, breakfast, regularity of meal time, frequency of snacks showed a positive relation to nutrient intakes in deaf-mute group and amount of meal, breakfast, regularity of meal time, frequency of overeating showed a positive relation to nutrient intakes in normal group. The nutrition knowledge had no correlation with food habits or eating behaviors in both groups.(Korean J Nutrition 35(9) : 982~995, 2002)

The aims of this study are to investigate the impact of the experience of exposure to domestic violence(witnessed interparental conjugal violence and child abuse) on mental health among college students, and to explore whether social support acts as a moderator between domestic violence and mental health. Through this process, I intended to provide a reference base to suggest substantial interventions for family welfare by helping students to overcome negative domestic violence exposure experiences and adapt as healthy members of society. To achieve this goal, the study established a conceptual framework by considering the mental health of adolescents with domestic-violence exposure experience as a dependent variable, domestic violence exposure experience (witnessed interparental conjugal violence and child abuse) as an independent variable, and social support as a moderator of the relationship between these two variables. The subjects composed 747 college students in 8 colleges in Seoul. The main summary of this study is as follows: First, according to the analysis of domestic-violence exposure experience, all the subjects of this study had substantial experience of violence at home and witnessed interparental conjugal violence. These students scored 3.83 points in social support, higher than the median of 3, implying that these students had a higher awareness of social support. Moreover, their mental health score was 3.50 points, which is higher than the median of 3, indicating a somewhat positive tendency toward mental health. Second, to explore the moderating effects of social support between child violence experience and mental health, gender, age, financial status, academic-performance, child abuse and social support were input in the first step, and then buffering effects were examined by entering an interaction term to the first step in the second step. There was a significant interaction between social support and mental health. Therefore, social support was identified as having moderating effects on the relationship between child violence and mental health. Third, the analysis of moderating effects of social support between witnessed interparental conjugal violence and mental health revealed that social support had a positive influence on mental health in the first step. By contrast, the interaction term of witnessed interparental conjugal violence and social support showed no significance, indicating no moderating effect of social support in the second step. To sum up, social support served as a moderator for mental health among college students with child abuse experience, but had no moderating effect on witnessed interparental conjugal violence experience.

The purpose of this study was to investigate the relationship between pack-years of smoking, metabolic biomarkers, and diet quality in male adults. We analyzed data from the combined 2007-2009 Korean National Health and Nutrition Examination Survey (KNHANES). The extent of smoking was quantified in pack-years (py), with 1 py equivalent to 20 cigarettes per day for 1 year. Subjects (n=1,318) were recruited and divided into two groups according to age (30~49 years age group, n=695; ${\geq}50$ years age group, n=623). In ach age group, subjects were divided into three groups according to the extent of smoking, which included non-smokers (30~49 years, n=156; ${\geq}50$ years, n=217), light smoker (30~49 years, n=269; py<16; ${\geq}50$ years, n=189, py<31), and moderate smoker (30~49 years, n=270; $py{\geq}16$; ${\geq}50$ years, n=217, $py{\geq}31$). The Nutrient Adequacy Ratio (NAR) and the number of foods (Dietary Variety Score, DVS) were analyzed by using the data from the 24-recall method. The results showed that moderate smokers were significantly more likely to drink alcohol compared with the other two groups. Triglyceride and cholesterol levels were significantly higher in smoker groups. The non-smoker group consumed significantly higher levels of vitamin C and potassium compared to the smoker groups. In the diet quality, vitamin C NAR of non-smoker group was significantly higher than those of smoker groups. In the ${\geq}50$ age group, the MAR of nonsmoker, light, and moderate smoker groups were 0.81, 0.78, and 0.78 respectively. The smoker group consumed significantly greate sugar and oils compared to the non-smoker group. Py showed a significantly positive relationship with serum triglyceride level, and a negative relationship with MAR after adjusting for potential confounding factors. In conclusion, male moderate smokers take too little vitamin C, partly due to low diet quality. Therefore, a well-planed diet must be used to replace the nutrients lost from excluded food groups in smoker.

Objectives : The purpose of this study was to determine correlation between coping strategies to disease and quality of life in chrome viral B hepatitis patients ; to investigate difference of coping strategies to disease and quality in life between chronic viral B hepatitis patients and normal persons ; and to identify major variables related to quality in life of chronic viral B hepatitis patients. Methods: The authors used Weisman coping strategy scale for measuring coping ability and efficacies, and the questionnaire for measuring quality of life including physical, psychological, social and economical aspects and satisfaction of sexual life was made by authors based on related literatures. Data were collected through questionnaire survey over a period from Sep 15, 1994 to Nov 11, 1994. Subjects served for this study consisted of 94 chronic viral B hepatitis patients visited to department of internal medicine at one general hospital and 100 normal persons visited to one general hospital for routine check up of health. The collected data were analyzed by SAS and the statistical methods for analysis were Chisquare, t-test and multiple regression analysis. Results : 1) It was revealed that coping strategies to disease significantly correlated to individual's quality of life. 2) There was no significant difference in coping strategies to disease between chronic viral B hepatitis patients and normal persons. However, chronic viral B hepatitis patients showed the lower scroes of quality of life in physical, psychological and economical aspects. 3) The most important variables which were influenced upon quality of life were coping strategies to disease and satisfaction of sexual life. That is, the more active coping strategies to diseases and the higher satisfaction of sexual life, consequently the higher quality of life was. Especially male patient group or normal persons showed each other the higher scores of quality of life in physical and psychological area than female group or patient group. 4) No statistically significant difference in coping strategies to disease and quality of life was found between HBeAg positive group and HBeAg negative group. Conclusions : The authors suggest that chronic viral B hepatitis patients may show the lower score of quality of life than normal person. Therefore, quality of life assessment should become an integral part of all clinical area that seek to assess the effectiveness of treatment. Also, through the interdisciplinary approach, a comprehensive paradigm that can better account for the effects of chronic disease on the individual' s quality of life should be developed.
