Rapid socio-cultural and economic changes in the country has brought with it changes in the society's value system. For a traditional society that is increasingly being exposed to modernization but where sex norms are still very restrictive, the adolescent sexual mores takes on added significance. Adolescents are caught between two opposing forces, the changing environment that allows for freer and liberal mores and the traditional society that cannot keep pace with the changing environment and therefore demands resistance to changes. This paper focuses on problems of adolescent sexuality in this country and considers the countermeasures for the existing problems. Amongst the problems are: (a) increasingly younger age of the adolescents who start sexual intercourse (b) non-use of contraception, (c) unwanted pregnancies, (d) increase in the number of induced abortion and (e) increase in the number of unwanted children and unmarried mothers. The Korean adolescent's sexual behavior seems to follow that of the developed countries. In other words, many western modes of life and sexual values seem to bave been copied in Korea and yet Korean adolescents lack in their knowledge of sex related matters such as reproductive physiology and contraception. Among middle and high school students, female students are reported to have less knowledge on sex than male students according to a 1988 survey by KIPH. Even among the unmarried famale factory workers, only 42.5 percent replied they know of the condom, and 25.1 percent and 23.1 percent said they had knowledge of spermicide and menstrual regulation respectively. However, 14.9 percent and 13.9 percent reported that they had a knowledge of the loop and female sterilization respectively according to the 1984 study by KIPH. Among the middle school students 0.8 percent said they had experience in sexual intercourse, while 7.3 percent of the high school students reported having had sexual intercourse. The sexual intercourse experience rate among the unmarried female factory workers is 37.8 percent. Among those female factory workers with sexual experience, 46.7 percent had more than one sex partners. Only 39.1 percent of male students and 18.9 percent of female students among those with sexual intercourse experience have used contraceptives. mostly condoms and oral pills 45.1 percent of female factory workers with sexual intercourse experience used contraceptives such as pills, condoms and rhythm methods. The pregnancy experience rate among the female factory workers who had experience in sexual intercourse is 29.5 percent, which is 11.1 percent among the total respondents. Out of the 102 pregnant female workers, 98 workers(96.1 percent) terminated their pregnancy by induced abortion and 2 workders(2 percent) in natural abortion, while 1 worker(1 percent) was in pregnancy and another 1 worker had normal birth that was subsequently sent to orphanage. In order to cope with the problem of adolescent sexuality, a drastic and strong policy measures should be taken by the government. The most effective countermeasure to the adolescent sexual problems appears to the education. The sex and population education in the school is very much in need. In addition, sex education program through mass media and at the job sit-should be promoted for a healthy development of adolescents' sexual behavior. Also, the existing national family planning program, which has focused on the married couples, should be extended to the unmarried people in its scope and contents of the program.

The purpose of this study was to elucidate the size and morphologic characteristics of maxillary primary first molars in Korean children using three-dimensional laser scanner and compare three-dimensional image with preformed stainless steel crown. Scanned three-dimensional images of dental cast taken from 132 children(male 62, female 70) by three-dimensional laser scanner(Breuckmann opto-Top HE100, INUS, Korea) were used. Mesiodistal diameter, buccolingual diameter, occlusogingival height and crown shape of each image were calculated by Rapidform 2004 program(INUS, Korea). The values were statistically compared by independent samples t-test with 95% of significant level. The results were as follows : 1. No significant difference in crown size was found between left and right maxillay primary first molar(p>0.05). 2, Significant difference in mesiodistal diameter, buccolingual diameter, buccal occlusogingival height was found between male and female (p<0.05), and crown size of male was bigger than that of female. 3. Average image of maxillay primary first molar was shaped three-dimensionally and measured. In comparison with 3M stainless steel crown, this image was similar with No.4 or No.5 SS crown in male, No.4 in female. In comparison with ILSUNG SS crown, this image was similar with No.5 in male, No.4 in female. 4 Mesiolingual line angle area, distolingual line angle area and buccogingival ridge were more obvious in average image than 3M stainless steel crown. ILSUNG SS crown was more square and had longer mesiodistal diameter than average 3D image.

The purpose of this study was to identify the mediating effects of self-esteem in the relationship between marital conflict and school adjustment among adolescents. This study used data collected from 482 middle school students in Seoul. Multiple regression analysis was used to examine the mediating effects of self-esteem in the relationship between marital conflict and school adjustment. The results of this study revealed that there were sex differences in self-esteem of adolescents. For both male and female adolescents, marital conflict was found to have negative effects on self-esteem. School adjustment of adolescents was found to be positively influenced by self-esteem. Marital conflict had negative direct effects on school adjustment only for male adolescents. Results indicated that self-esteem mediated in the effects of marital conflict on school adjustment for male and female adolescents. Implications for understanding the associations among marital conflict, children's self-esteem and adjustment in school contexts were discussed.

In this study, characteristics of cultural disposition and peer conflict resolution strategies and the relationship between cultural dispositions and peer conflict resolution strategies of elementary school children were investigated. In order to achieve this research purpose, the following research questions were established. First, what are the characteristics of cultural dispositions that children have? Second, what are the characteristics of conflict resolution strategies that children use? Third, what are the relationships between cultural dispositions and peer conflict resolution strategies? The subjects of this study were 564(283 male and 281 female) 5th and 6th graders. Research instruments used to collect data were INDCOL and Conflict Resolution Strategy Scale. Collected data were analyzed using Descriptives, t-test, Pearson's Correlation Coefficient, Cross-tabs and Two-way ANOVA. As a whole, children strongly showed collectivistic pattern and there were no sex differences in terms of cultural dispositions. The distributions of styles were in the order of HC>VI>VC>HI. The distribution of conflict resolution strategies generally were in the order of integrating and compromising>Avoiding>Dominating>Obliging for total sample and there were significant sex differences in the styles of conflict resolution strategies. This study also found that there were significant correlations between cultural dispositions and conflict resolution strategies. integrating/compromising and dominating style were different according to cultural dispositions but there were no interactive effect of sex and cultural dispositions in conflict resolution strategies. Finally, the implications of this study on theory and practice were discussed and suggestions for further study were made.

Objectives: This study was carried out with 31, 519(16,653 boys, 14,857 girls) of elementary school students to investigate the prevalence of obesity at a district in Gwangju City. It can be applied to develope an educational program of the obesity control as basic data in this local area Methods: The data collected from May, 2004 to July, 2004 were analyzed by SAS PC+ 8.0 program. Children were selected depending on criteria from obesity index (%) by using physical index (height, body weight), and then subjects were classified into one of three groups according to the degree of obesity: mild(20~29.9%), moderate(30~49.9%), and severe($?50%{\cdot}$) obesity. Results: It showed that male elementary school students were higher and heavier than female elementary school students(p< .001) in every grade except the 4th grade(height) and the 6th grade ( body weight). The obesity rates of male students(11.6%) showed higher(p< .001) than those of female students(8.8%). Specially the 4th grade elementary school boys were higher than any other groups in obesity(13.7%). As a whole, the prevalence of obestiy showed mild(5.9%), moderate(3.8%), and severe(0.6%). Male students showed higher rate of obesity than those of female students. The obesity of male students showed higher rate than that of female students except 2-3rd grade elementary school students(p< .001). The obesity of 4~6th grade elementary school students showed higher rate than those of 1~3rd grade students(p< .001). Conclusions: The obesity rates of male students are higher than that of female students, and the obesity rates of 4~6th grade students are higher than those of 1-3rd grade students in the elementary school. Additionally, these results suggest that the program may be needed to prevent obesity of children.

Anal endosonography has recently been popularized in adult patients in order to access staging of rectal cancer and other lesions of the anorectum. This study is not familiar to pediatric surgeons. We performed anal endosonography in 30 children without anorectal disease in order to determine the standard morphology of the anorectum. The internal anal sphincter(IAS) was clearly identified as a homogeneous hypoechoic circular band, extending caudally to a level just proximal to the anal verge. The external anal sphincter(EAS) showed mixed echogenicity and different architecture along the anal canal; the EAS was U-shape in the upper canal and it had a circular pattern in the lower canal. In the upper canal of girls, the perineal body and the vagina were found just anterior of the anal canal, which made the U shape of the EAS. In the male, the sphincter tapered anteriorly into two arcs that met in the midline. The perineal body was prominent in the female. Posteriorly, the anococcygeal ligament was represented by a triangular shadow in both sex. The thickness of the IAS was measured in 3 directions, left, right and posterior, at 3 levels, upper, middle and lower areas of the anal canal. The average thickness was 0.86-2.40 mm between 6 and 18 months of age(Group 1), 0.88-3.20 mm between 19 and 36(Group 2), 1.07-2.20 mm between 37 and 54(Group 3) and 1.18-2.42 mm more than 54-month-old(Group 4). The thickness was correlated with the age of the children only in the right upper(p=0.008) and the left middle portion(p=0.015). We were able to obtain standard morphologic features of the normal anal canal in children with anal endosonography. We believe that this technique is a safe and an effective procedure to evaluate anorectal lesions in children.

Objectives : This study was performed to investigate the injury rates and risk factors for preschool children in Daegu city and Kyungpook province. Method : A questionnaire survey about medically attended injuries during the preschool period was performed in nine primary schools located in Daegu city, Pohang city and Goryung County. The overall injury rate was estimated using person-year. The causes and patterns of the injuries, and their risk factors were examined. Result : A total of 469 medically attended injuries were reported in 330 of the 959 study subjects during the preschool period. The overall annual injury rate was 7.5 per 100 children. The injury rate increased sharply during the period from infant (2.4) to 1 year of age (7.5), and the peak injury rate (9.2) was reported for 5 year olds. The most common causes of injuries were falling (36.0%), followed by being struck by an object (23.7%), and traffic accidents (14.1%). Among the traffic accidents, 72.8% occurred while playing on the road, riding a bicycle or roller-skating. A proportional hazard model showed that males (hazard ratio=1.49, p<0.001 compared with female) and the mother's higher education level (hazard ratio of college or higher= 1.51, p=0.013; high school=1.32, p=0.085 compared with those of middle school or lower) were significant risk factors of childhood injury. Conclusion : The results of this study suggested that efforts for children's safety should be made, especially from the toddler stage, and in male children. To develop a more specific childhood injury prevention program, a surveillance system for injuries should be established. Further study of the relationship between mother's occupation and injury rates is also needed.

This study identified the relationship between perceived mother-grandmother conflicts and subjective well-being among multicultural children, and examined the double mediating model of acculturative stress and adjustment to school life on that relationship. Participants were 205 male and female adolescents living at J county in Gangwon-do. PROCESS Macro 3.5 Model 6 was used for analysis of a double mediating effect. Results revealed that perceived mother-grandmother conflicts was positively correlated with acculturative stress of multicultural children, and negatively correlated with adjustment to school life and subjective well-being. And, acculturative stress of multicultural children was negatively correlated with adjustment to school life and subjective well-being, whereas adjustment to school life was positively correlated with subjective well-being. This study found that acculturative stress and adjustment to school life were sequentially mediating perceived mother-grandmother conflicts and subjective well-being of multicultural children. These findings suggest that the perceived mother-grandmother conflicts might cause multicultural children to experience acculturative stress, and as a result, their subjective well-being level might be reduced due to their low adjustment to school life.

The relationship between copper content in scalp hair and mental retardation was investigated. Samples of scalp hair were collected from 297 mentally retarded children who were students in one of two schools providing special educational services, one, consisted of children living in an orphan home, the other, children living with parents. For comparison, 117 scalp hair samples were collected from the children who had got average or above average academic achivement in a regular elementary school. Hair samples were taken from the nape of the neck and the copper content was determined by an atomic absorption spectrophotometer (IL 551). There was no statistically significant difference in scalp copper levels across different age groups except female orphan group, but no trend or correlation between copper conents and age was found. The hair copper contents of the mentally retarded children groups were significantly lower than that of control groups. But there was no dose-response relationship between degree of mental retardation and hair copper level. The hair copper contents of the group accompanied by Down's syndrome and unknown group were significantly lower than that of control group in both sex, and in the case of accompanied by epilepsy or autism, lower than control group in male. Although the results of this study show no evidence that mental retardation has owed to copper deficiency, the possibility of copper deficiciency in their fetal or infant age could not be ruled out. Thus further study is needed to determine whether mental retardation could be attributed to copper deficiency, through the examinations about their living environments, dietary pattern, eating habit and the impact of copper deficiency on brain development.
