Objectives : This study examined the influence of socio-demographic, health-related, and oral health-related characteristics on adolescent DMFTs. Methods : The subjects in this study were 1,129 adolescents selected from the 6th national health and nutrition examination survey data. To determine the factors influencing dental caries, a regression analysis using a complex-sample generalized linear model was conducted after adjusting for confounding factors. Results : DMFTs were smaller among boys than girls, and smaller in the "13-15 age group" than in the "16-18 age group." In terms of household income, DMFTs were larger in the "lower," "lower-middle," and "upper-middle" income brackets than in the "upper" income bracket. DMFTs were smaller among adolescents with a history of smoking than those who had never smoked. Conclusions : In order to improve the oral health of adolescents, oral health-promotion programs should be provided for girls, high school students, students from low-income families, smokers, and those who consider themselves to have poor oral health.

Objectives : The purpose of this study was to examine the oral health knowledge, attitude, behavior among 918 secondary students and their needs for oral health education in Seoul, Gyeonggi Province and Choongbuk Province. Methods : The collected data were analyzed by the statistical package SPSS 18.0, and frequency analysis, correlation analysis, crosstabs, t-test and ANOVA were utilized. Results : The girls proceeded the boys in oral health knowledge, and the high school students were ahead of the middle schoolers in oral health knowledge, attitude and behavior. Those who ever received oral health education surpassed the others who didn't in oral health knowledge and behavior(p<0.01). The students hoped to be provided with oral health education by dental hygienists during regular classroom hours once per semester, 30 minutes to one hour at a once, and their favorite ways of oral health education were videotape watching and practice. As for needs for oral health education, the middle school students had higher needs for that than the high schoolers, and the former's needs scores were above the average(p<0.05). Conclusions : There were differences among the students in oral health knowledge, attitude and behavior according to their school system, gender and oral health education experiences, but oral health education was provided without taking their differences into account. It was recommended, efficient oral health education programs should be developed by focusing on how to take care of and prevent oral diseases, and videotape watching and practice that were preferred by the secondary students should be included in the programs.

This thesis seeks to inquire into the effect of group art therapy using a fabric medium on the emotional intelligence of middle school students. This application of fabrics to group art therapy is helpful in terms of gender roles and equality from an educational aspect and can help activate and control positive sentiment. Therefore, it was believed to have a positive effect on emotional intelligence. The subjects were 28 boys and girls who were students of the Supportive Project for the Priority Region of Educational Welfare Investment. The measurement tool is a revision of the emotional intelligence test of Mun Yong-Rin (1997), which itself was based on the emotional intelligence model of Mayer and Salovey (1997). The data materials are analyzed by SPSS (ver. 17.0 for Windows). To test the homogeneity of the groups, the Mann-Whitney U test was carried out, and to analyze the effect of this program, the Wilcoxon signed ranks test was carried out. The results are as follows. This program had a positive effect on the emotional intelligence of both male and female students, especially on their empathy and activation of thinking among the subcategories. This study has significance in that it verifies the effect of the improvement of emotional intelligence by way of group art therapy using fabrics, adding a fabric medium to the art medium. As the subject group was restricted to 28 adolescents in the Supportive Project, it is not easy to generalize the achievement to the entiresphere of group art therapy.

Milk contains a number of nutrients required for human growth and development, such as disaccharide lactose which is significantly contained in milk and dairy products. About two thirds of world populations are reportedly suffering from lactose intolerance after drinking milk. Lactose intolerance is defined as a maldigestion of lactose in the human intestine with typical symptoms of abdominal pains, bloating, and diarrhea. In this study, incidence of lactose intolerance has been investigated for the elementary school children for 1 year from July, 2010 to June, 2011. It is found that about 70% of the total elementary students have joined the school milk program. Out of 636 total students that participated in this study, 449 were from the metropolis, 85 from middle-sized city, and 102 from the small town including rural areas (small town/rural areas). For distributions of lactose intolerance, 154 students (24.2%) were found to be positive among the total 636 subjects. Based on the size of the city, the symptoms were the most prevalent for the students in the small town/rural areas at 31.4% (32/102), followed by 30.6% (26/85) in middle-sized city, and 21.4% (96/449) in the metropolis. On the other hand, gender had no significant effect on the incidence of lactose intolerance, shown those for boys and girls were 24.8% (77/310), 23.6% (77/326), respectively. Further research is needed to confirm the correct incidence of lactose intolerance symptoms as the frequency is significantly affected by subject's digestive functions including irritable bowel syndrome.

Given the 4 contexts-parents, friends, teachers and community- of adolescents, this research verified the casual relationships between each contextual support and the suicidal impulse, and the gender difference. The 4-year longitudinal data(KYPS) collected from 3,697 adolescents were used in this study. Using the Autoregressive Cross-Lagged Model, the suicidal impulse was consistently present from the 3rd grade in middle school to the 3rd grade in high school with significant stability. Gender differences were founded in the effect of parental support among the 3rd grade in middle school. Also the negative effect of friends' support on the suicidal impulse among the first grade high school students. The effects were more stronger for girls than boys. Previous supports by teachers and community had no significant effects on later suicidal impulses. These results suggest that the study of suicidal impulse needs to examine the complex support system of multiple context layers.

This study developed safety clothing that is essential for adolescent to protect their bodies from accidents, pursue activities and individuality. Therefore, the developed safety clothing was first based on international standards, while changing design to emphasize creativity, activity, and functionality. Two suits of boy's clothes and a girl's suit were developed as safety clothing for sportswear, along with two pairs of girl's clothes and a pair of boy's clothes for entertainment. It was confirmed that the difference in visibility was revealed by testing under different lighting conditions. Second, the survey on adolescents indicated no significant gender difference in sportswear. Round shirt+shorts for both boys and girls were the most preferred for ball game sportswear. However, there was a significant difference by gender in the design of safety clothing for entertainment. Male students preferred jump suit=cape+pants the most, and female students preferred jump suit>cape+pants in the order (p<0.05). In the safety clothes with the highest preference for entertainment, there was no gender difference. All students preferred the jump suit at the most. Checking at each school level, it was found that both middle and high school students preferred jump suit designs, and in safety clothing, middle school students preferred high-neck shirt blouse+tight skirt, and high school students preferred jump suits. Third, 35.5% responded that they would wear it more if current safety clothing is improved. This indicated the necessity of developing various safety clothing for adolescence.

This study was intended to investigate actual conditions and problems relating to a variety of substance which have been used by students. A Questionnaire survey was carried out with the subject of 2411 students in an academic boys' high school, academic girls' high school, technical boys' high school and technical girls' high school in Pusan, from the 15th day to 29th day of March, 1989. The summarized results were as follows. There was not a remarkable difference in distribution of these subjects in boys' & girls' high school. The common and good health condition of subjects accounted for 90 percent or higher. 24.4 percent of them also had smoking experience, 11.6 percent of which continues to smoking. The understanding rate of these substances name other than sedative, psychostimulants and antihypnotic accounted for 90 percent or higher. The experience rate taking these substances for one year showed that anodyne, digestive and nutritive tonic accounted for 70 percent, antihypnotic for 15.6 percent, sedative for 1.4 percent, respectively, and psychostimulants for 0.5 percent. Moreover. it was shown that drugs accounted for 1.5 percent, bond for 1.4 percent, and thinner for 0.5 percent. The rate of the daily experiencers who took anodyne, digestive, nutritive tonic, sedatives, and psychostimulants and so on was 7.7 percent, 6.2 percent, 5.2 percent, 5.9 percent, and 5.0 percent respectively. This fact implied that there was a serious problem in high school students' non - narcotic abuse. The usage rate of these substances for treatment purpose showed that anodyme accounted for 90 percent or higher, and digestive for 70-80 percent, respectively, where girl students showed higher rate than one of boy students. Additionally, there was higher the usage rate for other purposes. The usage rate of drugs was highest when these students felt melancholy and curiousity. Their obtaining place appeared that these students mainly obtained these drugs, bonds and thinners from a small shop or peddler and their friend while they usually obtained other substance from the pharmacy and medical institute. The first usage time of these substances appeared during the middle school (the age of 14-15) which was the highest rate. The smoker of all subjects used remarkly large substances as compared with one of no-smoker. Particularly, it appeared that the usage of drugs was very closely related to smoking. The large number of students did not use these substances for oesrable purposes even though they understood the name of these substances. For this reason, from primasy schools it is required to teach the students dependence and harmful effects caused by these substances abuse. Moreover, it was shown that these students firstly used these substances during the middle school (the age of 14-15)due to curiosity. As a result, it is very urgent to give the students health education suitabale for prevention of these substance abuse, when considering harmful effects of these substances. And so health education for no-smoking. Finally, considering that it is very easy to obtain these substances from a small shop and pharmacy, the regulation of these substances control should be considered and completed in the future.

This study was performed to test the validity and reliability of the Health Self-Determinism Index for Children(HSDI-C), an instrument designed to measure dimensions and strength of motivation in health behavior, to improve the applicability of the tool through application to the various samples. The convenient sample of 148 (boys=75, girls=72 third grade=42, fourth grade=22, fifth grade=32, sixth grade=52 : Caucasian=72, Asian=30, African=19) comprised the children at a chatholic elementary school in Chicago. The children completed English version of HSDI-C from December 5th, 1994 to January l0th, 1995. The findings were as follows : 1. Four factors of HSDI-C were isolated through the principal component analysis and oblique rotation, and explained 48% of the variance in total score. Low correlations among four factors were anticipated because each factor contributed uniquely, All items of the tool loaded above .30 on one of 4 factors. But items loaded on each factor in this study were very different from those in the previous studies. 2. Cronbach's alpha coefficient for internal consistency was .81 for the total items and .57∼ .81 for 4 subscales. 3. The differences of HSDI-c mean scores between boys and girls and that of among races were not statistically signifcant, but the mean score of girls and the Caucasian were relatively high. The total mean score of the scale was highest at the 3rd grade, decreased at the 4th or 5th grade, and reincreased at the 6th grade. The trend of mean score of four subscales was similar to that of total mean score. According to the results, suggested below : 1. The items loaded on each factor in this study were very different from those in the previous studies. To clear away the problem of the conceptual confusion, HSDI-C needs to be performed to various and large samples. 2. Unexpectedly, the HSDI-C mean score decreased at middle school age. A longitudinal study will be helpful to search for the change trend of the intrinsic motivation. 3. To improve the applicabilty of the HSDI-C, various reliability and validity test methods besides factor analysis or internal consistency are recommended.

The purposes of this study were 1) to identify the effects of age and sex on adolescent's psychological characteristics-egocentrism, self-consciousness, body cathexis and clothing behaviors and 2) to identify the effects of psychological characteristics on clothing behaviors in each of the 6 groups classified by sex and age. Egocentrism was measured by Kim's Imaginary Audience Scale, and body cathexis, by the modified record and Jourard"s Body Cathexis Scale. Buss's Self-Consciousness Scale was slightly modified to assess public and private self-consciousness, and five aspects of clothing behavior were assessed with the questionnaires from the previous studies. The questionnaire were administered to 713 middle and high school boys and girls, and college students living in Seoul. Data were analyzed by frequency, factor Analysis, two-way ANOVA, and multiple regression analysis. The results of this study were as follows: 1) Four factors of egocentrism were identified : Potency, Appearance/populatity, Sympathy and Justice. Four factors of clothing behavior were Clothing exhibition/dressing for others, Clothing interest, Psychological dependence, and Clothing conformity. 2) Sex and age were found to have effects on psychological variables and clothing behaviors of adolescence. Females showed higher egocentrism, self- consciousness, clothing behaviors, but lower body cathexis than males. The mean scores of egocentrism, self-consciousness, clothing behaviors tended to increase with age. However, high school boys showed unique tendency, as they showed higher scores in those variables than the other two age groups. 3) Egocentrism (Appearance/populality factor) and public self- consciousness were the most influencial variables on adolescent's clothing behavior among psychological characteristics. Private self-consciousness was found to be an important variable in explaining Psychological dependence.ence.
