Since it is favorable to include the incipient caries lesion in the diagnostic criteria in adolescence, this study had surveyed dental caries status of adolescents at ages of 13 and 16 by using WHO basic methods and ICDAS-II codes. In this study, mean DMFT index was 3.71, and mean DT index was 1.94. For both indices, the age 16 group showed higher values than the age 13 group. By groups of teeth, DMFT index and DT index exhibited highest to the lowest values in molar, premolar, and anterior teeth, respectively. 77.46% of total numbers of teeth were classified as code 0 in ICDAS-II. Compared to anterior teeth, numbers of decayed teeth were increased in posterior teeth. All caries lesions in anterior teeth and premolars were limited to enamel. ICDAS-II code is an useful method to detect the incipient caries lesion, allowing preventive control on caries management.

Purpose: This study intended to identify personality factors and related problematic behaviors of adolescents who drink alcohol in order to provide basic data for developing nursing programs. Methods: The data were collected from October to December 2002 from 1.080 high school students in Seoul. The Revised Cloninger's Tri-dimensional Personality Questionnaire (TPQ) was used to measure their personalities. The alcohol expectancy was measured using the tool revised by Cho (1999) and stress levels were measure using a stress tool revised Cho (1998). The data were analyzed with SPSS Windows using Chi square test. independent t-test. and logistic regression analysis. Results: 1. The percentage of fathers who drank was 79.8%. mothers. 54.3%. and friends. 54.3%. The alcohol expectancy averaged 6.36 while the stress levels were 132.79. 2. It was found that there are significant differences (p<.001) in problematic drinking behaviors according to the following variables: second year high school students among all grade variables, more monthly pocket money for the amount of money variables, the group of students who smoked in the case of the variable related to smoking, spending more time using the Internet for the Internet use variable, and having friends who drink 65.6% for the friend variable. The alcohol expectancy scale of those students who showed problematic drinking behaviors was higher than that of those who did not. There are four family-related stress subscales, and there was a significant difference among them (p<.05). Among the personal characteristics, the group who displayed problematic drinking behaviors seeks new experiences and reward dependence more than the group who did not exhibit those behaviors, and there were significant differences between the two groups (p<.001). 3. When the socio-demographic and drinking-related factors were controlled, the tendency of seeking new experiences increased the risk of problematic behaviors 1.07 times (p<.05). Compared to the non smoking group, the smoking group was found to have a 5.06 time (p<.001) greater risk of displaying problematic drinking behaviors. In comparison with the non drinking group, the drinking group was also found to have a 5.31 time (p<.001) greater risk of exhibiting problematic drinking behaviors. The group with high alcohol expectancy scores was significantly different from the group with the no alcohol expectancy, showing a 1.26 time (p<.00l) greater risk of problematic drinking behaviors. Conclusions: Based on these results, the problematic drinking behaviors were connected with alcohol expectancies, friends and personality types. Therefore, we should develop an alcoholic prevention program for adolescence considering the above results.

This study was conducted to identify the level of sexual awareness and the demand for sex education, to investigate the attitude toward and acceptance of heterosexual friendship, and to identify the experience and direction of sex education of parents. The data were collected from 119 parents with high school students by the structured questionnaire from June 1, 2001 to August 31, 2001. Parents and teachers showed a similar attitude on sexual awareness, but teenagers showed a different attitude. In terms of the level of feeling of and interest in 'sex', teenagers, parents and teachers were comfortably accepting it. As for sexual curiosity in puberty, 84.8% of the parents and 95.5% of the teachers responded that it was natural, whereas only 14.7% of teenagers responded that it was natural. But As for the item that 'sex is natural as one of human needs', 3.6% of the teenagers, 16.8% of the parents and only 1.2% of the teachers responded that it was not. As for the item that 'Man have a stronger sexual impulse than woman", 6.1% of the teenagers, 16.8% of the parents and 17.3% of the teachers responded that it was not. This indicates that teenagers have a far stronger sexist awareness, which also reflect that the sex culture of Korean society that regards sex as man's sexual monopoly. 64.2% of the teenagers and 90.2% of the teachers responded that it was impossible to overcome the sexual impulse, whereas only 8.4% of the parents responded that it was possible. As for the item of masturbation, 64.5% of the teenagers responded that it was possible for male students and not possible for female students. 67.2 of the parents and 91.1% of the teachers responded that it was possible regardless of sex. In case of pregnancy in adolescence, most of the responding teenagers, parents and teachers chose abortion. This indicates that respondents have a poor basic understanding of the life-despising climate, responsible sexual intercourse and motherhood protection. As for the item of 'female refusal on male sexual approach', respondents accepted female refusal as it was in orders of teachers, parents and adolescents. As for item of 'An assaulter is entirely to blame for sexual assault', all of three groups responded in the affirmative.

The purpose of the study is to assess and evaluate methods employed in nutrition surveys and to give an information on methodological considerations for future studies in Korea. Three hundred thirty six papers of nutritional surveys published from 1960 to 1990 were classified into 9 groups according to the survey subject and analyzed for methods used in survey. The frequency of publications according to the survey subject was as the following order : 'in-fants and preschool children' 'school age children' 'adolescence' 'college students' 'preg-nant and lactating women' 'housewives' 'the elderly' 'workers' and 'patients' Eighty five percents of papers applied methods of dietary assessment. of which weighing method recall method an record method were extensively used in the order. Questionnairs included items related to nutrition such as food habit nutrition knowledge etc. Anthropometric techniques were employed in 53% of papers and in general growth measurement were undertaken for children and body composition was emphasized for adults. biochemical assessment was limited to 32% of papers and assessment of anemia was the major test. Clinical studies were applied to 26% of the studies. of which only 5% employed examination of clinical signs of malnutrition Recently self-reported health status assessed using questionnaires has been adopted frequently. Further researches are required for evaluation of the methods employed in nutrition surveys in order to develop the standard model for nutrtion survey so that obtained data can become more reliable and utilized efficiently.

The purpose of this study is to provide some information for the proper education on clothing wearing habits so that the education may be performed in the direction of social needs according to the social change and in the direction of the needs and interest of the high school girl students in their adolescence by being conscious of the influence of clothing on the high school girl students. I have used questionaire as an instrument of measurement. The length of the time of survey is from February 11, 1991 to February 28. The subjects are 544 first grade girl students of general high schools in Cheong-Ju, Choong-Ju, and Je-Cheon. The analysis of the data includes frequency, percentage, average person's Correlation Program, t-test, ANOVA, Scheffe's test. The conclusion of this study is as follows: The first, it is shown that (l)students's interest in the design and fashion of clothing is significantly related to the socio-anthropological and socio-psychological factors such and the education level of their fathers, the education level of their mothers, monthly income of their homes, the clothing habits of their home economics teachers, the subjects which they are interested in, their average scholoary achievements, their religious background, and whether they have boy friends or not, etd. (2)students' interest in purchasing of clothing is significantly related to the socio-anthropological and socio-psychological factors such as the education level of their fathers, the education level of their mothers, monthly income of their homes, the clothing habits of their home economics teachers, the subjects which they are interested in, their average scholoary achievements, and whether they have boy friends or not, etc. (3)students' interest in the social-psyclological aspect is significantly related to the socio-anthropological and socio-psychological factors such as their living area, the clothing habits of their home economics teachers, etc. (4)students' interest in the clothing construction is significantly related to only the clothing habits of their home economics teachersl. (5)students' interest in the clothing management is significantly related to the socio-anthropological and socio-psychological factors such as the education level of their parents, the age of their mothers, their religious background, and their sisters. The second, as for the interest of the high school girl students in clothing, it has been shown that those who wear school uniforms tend to have more interest than those who wear free-choice clothes in such areas as shopping, the construction, and management. As for the other two areas, that is, disign and fashion, and the interest in socio-psychological dependence there has been little meaningful difference between the two groups, while the uniform group has shown more interest than the other group. The third, the interest of hish school students in clothing is considered to be most seriously influenced by their socio-psychological dependence out of five areas of interest. It has been shown that the proportion of the content dealing with clothing wearing life in the high school home economics texbooks in relatively small, especially in such areas as socio-psychological dependence, shopping, management, and design and fashion except in construcion.

Objectives : This study was aimed at investigating the relationship between internet game addiction and emotional and behavioral characteristics of students both in the 5th and 6th grade of elementary school and in middle school. Methods : Two elementary schools and two middle schools were chosen to participate. The students completed selfreport questionnaires designed by the authors, called the Internet Game Addiction Scale, Korean youth self-report (K-YSR). Results : Compared to previous studies, the rates of those in the obvious game addiction group were much lower in this study. We defined the upper 10% of internet game addiction scores as a high risk user group and the lower 10% as a control group. There were significant differences between the groups with respect to the the ages at which internet gaming began, the frequency of game play per week, and the average length of each game playing session. Significant associations were also found between the level of internet game addiction and the withdrawn and delinquency subscales of the K-YSR. However, the association between game addiction and the withdrawn subscale was found only in middle school students. Conclusion : The findings from this study suggested that withdrawn and delinquent behaviors could be predictors of internet game addiction. Results also suggested the importance of early childhood intervention for preventing the development of more severe psychopathology in early adolescence.

This study was done to investigate the effect of adolescent smoking on dietary intakes and nutritional status of serum lipids and antioxidant vitamins. Subjects were 82 somkers whose average pack-year was 0.73, and 85 nonsmokers of male technical high school students in Seoul. Anthropometric measurement was performed and % body fat was also analyzed by Bioelectrical Impedance Fatness Analyzer(GIF-891). Dietary intakes and habits were examined through questionnaires and nutrient intakes were analyzed by Computer Aided Nutritional (CAN) analysis programs. Serum TG and total cholesterol levels were measured by Spotchem sp-4410 and serum HDL-cholesterol levels were measured by test kit. serum vitamin C level was measured by 2,4-dinitrophenylhydrazine method and serum levels of vitamin A and vitamin E were measured by HPLC. All data were statistically analyzed by SAS PC package program. There was a significant difference in body fat percentage and systolic blood pressure while other anthropometric measurements were not different between smokers and monsmokers. Caloric intakes(2335㎉) in adolescent smokers tended to be higher than that of nonsmokers (2,175㎉) but the difference was not statistically significant. Intakes of protein(76.67g) and niacin(16.49㎎) in adolescent male smokers were significantly higher(P<0.05) than those of nonsmokers although other nutrient intakes were not significantly different. Analysis of serum lipids showed that serum HDL-cholesterol level of smokers was significantly different. Analysis of serum lipids showed that serum HDL-cholesterol level of smokers was significantly lower(p<0.05) than that of nonsmokers, whereas other lipid levels were not significantly different. Serum vitamin C level was also significantly lower(p<0.05) in adolescent smokers than in nonsmokers. In addition, serum vitamin E level, which was 7.85㎎/1 in smokers, was lower than that of 9.20㎎/1 in nonsmokers(p<0.05) while serum vitamin A level was not significantly different between the two groups. These results indicate that cigarette smoking in adolescence decreases serum levels of HDL-cholesterol, vitamin C and vitamin E even thoughth their smoking history is very short.

Objectives: "Internet-addiction" came into common use not only in clinical setting but also in everyday life. But, pathophysiology and diagnostic criteria of the internet addiction remain unknown. Because adolescents are in developing period, they might be vulnerable to the internet addiction, depression and sleep-related problem. The objectives of this study were to investigate the characteristics of internet addiction and its association with sleep pattern and depression in Korean adolescence. Methods: Subjects were 799 middle and high school students in Seoul, Korea. We administered a self-reported questionnaire including socio-demographic data, Korean versions of Young's Internet Addiction Scale (YIAS), Pittsburgh Sleep Quality Index (PS-QI), the Center for Epidemiologic Studies for Depression Scale (CES-D) and questions about internet using patterns. Data of 696 subjects were included in analysis. Chi-square tests were used to analyze proportional differences, and ANOVA with post-hoc tests were used to analyze differences among groups. Partial correlation analyses were performed to analyze the correlation of internet addiction with other variables (two-tailed, p<0.05). Results: Of the 696 participants (grade 2 of middle school; M2 135 vs. grade 1 of high school; H1 238 vs. grade 2 of high school; H2 323), 2.0% (n=14) were internet-addicted (IA), 27.7% (n=193) were over-using (OU) and 70.3% (n=489) were not-addicted (NA). The mean scores of YIAS, PSQI and CES-D scores were 35.24${\pm}$12.78, 5.53${\pm}$3.04 and 16.72${\pm}$8.69, respectively. In higher grade students, average total sleep time was shorter (M2 426.20${\pm}$67.68 min. vs. H1 380.47${\pm}$62.57 min. vs. H2 354.67${\pm}$73.37 min., F=51.909, p<0.001), and PSQI (4.69${\pm}$3.14 vs. 5.42${\pm}$3.15 vs. 5.97${\pm}$2.83, F=8.871, p<0.001) CES-D (13.53${\pm}$8.37 vs. 16.96${\pm}$8.24 vs. 17.87${\pm}$8.84, F=12.373, p<0.001) scores were higher than those of lower grade students. Comparing variables among IA, OU and NA groups, computer using time not for study (96.36${\pm}$63.31 min. vs. 134.92${\pm}$86.79 min. vs. 213.57${\pm}$136.87 min., F=34.287, p<0.001) and portable device using time not for study (84.22${\pm}$79.11 min. vs. 96.97${\pm}$91.89 min. vs. 152.31${\pm}$93.64 min., F= 5.400, p=0.005) were different among groups. PSQI (5.26${\pm}$2.97 vs. 6.08${\pm}$2.97 vs. 7.50${\pm}$4.41, F=8.218, p<0.001) and CES-D scores (15.40${\pm}$8.08 vs. 19.05${\pm}$8.42 vs. 30.43${\pm}$13.69, F=32.692, p<0.001) were also different among groups. YIAS score were correlated with computer using time not for study (r=0.356, p<0.001) and portable device using time not for study (r= 0.136, p<0.001). PSQI score (r=0.237, p<0.001) and CES-D score (r=0.332, p<0.001). YIAS score and PSQI score (r=0.131, p= 0.001), YIAS and CES-D score (r=0.265, p<0.001), PSQI score and CES-D score (r=0.357, p<0.001) were correlated each other. Conclusion: These results suggested that adolescents' internet-addiction was correlated with not only computer and portable device using time not for study but also depression and sleep-related problems. We should pay attention to depression and sleep-related problems, when evaluating internet-addiction in adolescents.

Objectives：The purpose of this study was to evaluate suicidal attitudes, self-image, anxiety and depression on industrial and cultural wemen's high school, and to make a comparative study between suicidal attitudes and anxiety, depression, self-image. Methods：Three hundred twenty-six student(161 persons from industrial wemem's school, 165 persons from cultural wemen's school), who were supposed to different from in psychosocial environment, entered this study. To assess the attitudes toward suicide, Suicide Opinion Questionnaire(SOQ) were done at study. To estimate anxiety, depression, and self-image, Zung' Self-rating Anxiety Scale (ZAS), K-Beck Depression Inventory(KBDI), Offer's Self Image Questionnaire(OSIQ), respectively, were executed in this study. Results：1) We extracted 5 factors after factor analysis based on SOQ results with the response of the 326 subject；ethics, religion, mental illness, acceptability, revenge. Revenge factor were stastically significant between both groups. 2) In OSIQ, family relationship factor & superior adjustment factor were stastically significant between both groups, but, both groups didn't have a significance on ZAS & KBDI. 3) According to correlative analysis between SOQ results and OSIQ, ZAS, KBDI results, ethics factor(SOQ) were converse to BS factor, ET factor, and ME factor in OSIQ. Mental illness factor(SOQ) were in proportion to PP factor(OSIQ). Acceptability factor(SOQ) were in proportion to ZAS & KBDI result. Conclusion：Our subject mostly regarded suicide as sinful ethically ,and as mental illness. But, In that there was neuropsychiatric history and suicidal idea in them, the subjects looked upon suicide as permissive. With significantly high score on ZAS & KBDI, there were more acceptable attitude toward suicide. So, We consider suicide to be used as coping strategy about more stressful event to young adolescent.
