The purpose of this survey, in which 2754 students from 35 middle schools from Taegu city participated, was to identify the degree and the relationship of sexual knowledge, sexual attitude and need for sex education. This information will provide useful data, and promote a more systematic, desirable and practical sex education. The data was collected from September 1 to November 8, 1997. Data was analyzed using the statistical computer package, SPSS to manipulate the data along with percentage, mean, $X^2$-test. t-test, F-test and Pearson correlation coefficient. The results from this study were summarized as follows: 1. The mean score of sex related knowledge showed significant differences between boys and girls in general knowledge(boys: 10.85 girls: 11.71, p=0.000), in the area of physical development(boys : 5.29 girls: 5.72, p=0.000), pregnancy & physiology (boys: 3.23 girls: 3.57, p=0.000) and venereal disease (boys: 2.33 girls: 2.42, p=0.000). 2. The mean score of sex related attitudes showed a significant differences between boys and girls on the whole(boys : 57.68 girls: 58.92, p=0.000), in the area of psychological differences of the other sex (boy: 26.13, girls: 28.08, p=0.000), and sexual delinquency and its prevention(boy: 14.28, girls: 13.68, p=0.000). However, in the area of other sex friendships (boy: 17.28, girls: 17.16, p=0.274). There were no significant differences between boys and girls. 3. Those who had a higher sex related knowledge score showed more positive attitudes towards sex, but was of no statistical significance(r= 0.312, p=0.000). 4. The majority of subjects wanted to learn about friendship with the other sex(40.1%), about physical and psychological differences in adolescence(24.0%), about prevention of sexual violence(15.0%), about pregnancy and delivery (7.5%), about venereal disease and medical cures(7.3%), about contraception methods (4.3%), as well as other aspects of sexual knowledge (1.8%), 5. The mean score of sex related knowledge generally was higher when one paid a lot of attention to health (F= 3. 148, p=0.014), when one's father was alive(t=3.930, p=0.000), and when one's mother was alive(t=2.807, p=0.005), Hobby activities also showed a significant difference(F=9.092, p=0.000). The mean score of sex related knowledge generally according higher when one had sex education(F=9.470, p=0.000), when one obtained sexual knowledges from a teacher (F = 5. 742, p=0.000), and when one had middle grade problems with sex(F=13.58 4, p=0.000). 6. The mean score of sex related attitudes generally showed significant differences when re ligion(F=2.691, p=0.03), hobbies (F= 3.499, p= 0.002) were considered. Those who had a father also had higher scores(t=2.538, p= 0.011). The mean score of sex related attitudes generally with respect to a subject's sex was higher when one had sex education(t=5.338, p= 0.000), when one had high grade problems with sex(F=6.023, p=0.002), and when one had the experience of friendship with the other sex(t= 8.106, p=0.000), The following suggestions are based on the above results, 1. Systematic sex education must be performed in middle schools in order to establish responsible attitudes toward sex, 2. Sexual knowledge, attitude, and general sex education classes must be performed seperately for early, middle, and late adolescents, In other words sex education programs are needed for each adolescent development stage.

Objectives: This study was taken to investigate factors related to dental caries in deciduous teeth of preschool children. Methods : this study was completed by oral examination on 623 kindergarten pupils and questionnaire on their mothers in Sangju city from April 1 to May 20, 2001. Study design is Cross-sectional Study. Results: The mean values for decayed teeth indexed(dt index), filled teeth index(ft index), and decayed and filled teeth index(dft index) was 2.46, 1.85, and 4.30 respectively. 2.05 for girl was significantly lower than 2.77 of boy in gender (p<0.01). As child ren got older, values were higher(0.7 and 2.84 of three years old, 1.6 and 4.01 of four, 2.42 and 5.02 of five) in ft and dft index(p<0.001). Also, Mother age was almost same, that is, 4.12 dft value for 30~34 years was smaller than 6.17 for above forties(p<0.001). 2.07 and 4.68 for mothers who graduated from high school were higher than 1.36 and 3.34 for university in the ft and dft index(p<0.05), that is, the more they had a high educational level, the lower they got a values. Value 2.76 for children who had non cariogenic food was lower than 5.11 for those who had cariogenic food in dft index(p<0.001). In dft index, 3.82 of children who have learned the education on oral health from mother frequently have lower than 45 of children who have never learned (p<0.05). The ft value of children who had a snack food with mother(1.29) was a smaller than children had it at out of home(1.97)(p<0.05). The variables related 10 dft index were children and mothers age, educational level, and kinds of snack food (p<0.05). Conclusion : This study reveals that younger girl, younger mother, higher educational level, and non cariogenic foods showed lower dft index.

Paragonimiasis is a parasitic infection that occurs following the ingestion of infectious Paragonimus metacercariae from crabs or crayfish. Pulmonary paragonimiasis is the most common clinical manifestation of this infection, but several ectopic paragonimiasis cases have also been reported. Among them, cases of subcutaneous paragonimiasis are rare, especially in children. We report a case of subcutaneous paragonimiasis of the right abdominal wall with pleural effusion with hepatic involvement and without abnormal pulmonary infiltration in a boy aged 2 years and 5 months. He had eaten soybean sauce-soaked freshwater crabs (kejang) 6 months prior to complaining of right abdominal wall distension. On evaluation, right pleural effusion without abnormal pulmonary infiltration was detected, as well as blood eosinophilia, an elevated serum IgE level, pleural fluid eosinophilia and a positive enzyme-linked immunosorbent assay that detected P. westermani antibody in the serum. Thoracentesis, praziquantel administration, and excision of subcutaneous lesions were performed. After treatment, the eosinophil count and serum IgE level were decreased, and the subcutaneous lesions did not recur. The frequency of paragonimiasis has decreased recently, but it is still prevalent in Korea. Paragonimiasis should be suspected if pleural fluid eosinophilia is associated with blood hypereosinophilia and a high level of serum IgE; however clinicians should obtain a thorough history of travel and food habits.

Retroperitoneal cystic lymphangiomas are benign, extremely rare tumors. Although surgical resection is the treatment of choice, sclerotherapy should be considered initially. A 9-year-old boy was admitted due do worsening abdominal pain of 4 days duration. Serial complete blood counts revealed a hemoglobin level of 12.8 g/dL on admission to 10.6 g/dL on hospital day 3. An abdominal computed tomography (CT) scan showed a large, lobulated, septated, retroperitoneal cystic mass ($10{\times}9.5{\times}5cm$) in the left anterior pararenal space with intracystic hemorrhage surrounding the inferior mesenteric vein (IMV). Because of the high operative risk, we performed a tubogram of the cystic mass, percutaneous catheter drainage (PCD), and ethanol sclerotherapy. The follow-up abdominal CT scan showed that the cystic mass had decreased in size. He is well without relapse of the retroperitoneal cystic mass for 13 months after discharge. Sclerotherapy with PCD should be considered as initial therapy for patients with retroperitoneal cystic lymphangiomas at high surgical risk.

A number of schools have introduced the Reward and Punishment Mark System. It has been applied to children at school in order to minimize the ill effects that are often caused by physical punishment. In this case, teachers have caused problematic issues in the course of student life guidance at school. However, the application of the personal Reward and Punishment Mark System raises many other questions as well. Accordingly, there is the necessity of making up for its weak points on the systematic level. The purpose of this study is to understand the Effect of the Collective Reward and Punishment Mark System, as a substitute punishment to the physical punishment, applying the reward and punishment mark system not to an individual but to a group. The Collective Reward and Punishment Mark System for the upper grade students of primary schools showed a positive effect which assists their adaptation to school. To put it more concretely, according to the characters of the study subjects, the system has proved that boy students are more positively affected than girl students. It has been also revealed that those students in the fourth grade experience a positive change in all areas of the adaptation to school, while those in the fifth and the sixth grade were negatively affected. Moreover, those who hold a lower rank in respect of grade achievement experienced a more positive change than those standing among a high rank. It is expected that the Effect of the Collective Reward and Punishment Marks System, on the basis of the study, possesses affirmative intervention on the field.

Oculo-cerebro-renal syndrome, known as Lowe syndrome, is an X-linked gene disorder characterized by congenital cataracts, brain abnormalities and renal dysfunction. Tooth crowding, taurodontism, delayed eruption in the permanent dentition and over-retained primary teeth with ectopic eruption of the permanent teeth have been reported as dental findings. Because of the high incidence of poor cooperation, patients with Lowe syndrome have difficulties in maintaining good oral hygiene, which may require dental treatment. We present a case of dental treatment for the uncooperative child with Lowe syndrome under general anesthesia. A 4-year-old, 11.2 kg boy with Lowe syndrome visited Seoul National University Dental Hospital for gingival swelling. The patient had multiple caries requiring dental treatment. Because of his past history of malignant hyperthermia during inhalation induction, anesthesia was induced and maintained with total intravenous anesthesia (TIVA) after medical consultation. Dental restorative treatments were successfully performed and no complications were observed during and after the procedure. Safe and effective dental management of the patients with Lowe syndrome could be performed with the help of general anesthesia and careful monitoring.

The study of the visual acuity and refraction status was performed to the students of primary school using eyeglasses in Kyung Nam region, Korea. Two hundred sixty three subjects with various styles of ametropia were analyzed the visual acuity and refraction examination by the subjective and objective tools. The results of study were as follows; 1) According to the increase of age of subjects, the visual acuity of binocular in naked eyes was decrease. However ametropia was increase. 2) The high frequency of ametropia types in the binocular was simple myopia, and the next order of high frequency was mixed astigmatism, myopic compound astigmatism, simple hyperopia, and hyperopic compound, respectively. 3) On the power of spherical refractive error of ametropia, the high frequency was -1.00 diopter, and the next order of high frequency was -2.00 diopter, +2.00 diopter, -3.00 diopter, and so on, respectively. 4) According to the increase of subjects ages, the changes of dioptric power of myopic spheric power was increase. however the frequency of the boy and girl was similar results, also the dioptric values of refractive status in binocular was similar results. As the results of this study, we conclude that the relationship of the visual acuity and refractive error status in primary students using eyeglasses was improved.

Data were collected from 310 6th, 7th, and 8th grade students and parents by questionnaires and analyzed by t-test and multiple regression analysis. The higher parents attachment and parents monitoring, the higher prosocial behavior towards parents and siblings, the higher perspective-taking, the higher prosocial behavior towards parents, and the higher socioeconomic status, the higher prosocial behavior towards siblings. More prosocial behavior toward parents was reported by girls than by boys. Prosocial behavior toward siblings did not show a gender difference. In the total group, high parent attachment and perspective-taking predicted prosocial behavior towards parents; high parent attachment and socioeconomic status predicted prosocial behavior towards siblings. In the boy group, high parent attachment and perspective-taking predicted prosocial behavior towards parents; high socioeconomic status predicted prosocial behavior towards siblings. In the girl group, high parent attachment predicted prosocial behavior towards parents and high parent attachment and socioeconomic status predicted prosocial behavior towards siblings. Discussion focused on the relative importance of parents attachment, perspective-taking, and socioeconomic status in predicting early adolescents' prosocial behavior.

Before the modern education was introduced in Korea men had the opportunity to be educated. Women's education was limited to a small number of girls belonging to ruling class. It was the men who got a job to earn the money for the family. The customary law prohibited women from being employed. They were to stay at home engaged in household affairs. This phenomenon has undergone a change when modern education was adopted which gave women the equal opportunity in education. The modernization of the country required a lot of educated and skilled labour. Since 1945 when Korea was liberated from the Japanese colonial administration the modernization programme has been worked out in every field such as industry, education, culture and politics, etc. The traditional grand family was transformed to nuclear family. The migration took place from country to town. With the adoption of compulsory education in the primary school the schoolgirls are increased in great number. The number of girls has been increased every year in Middle Schools, High schools and Universities. Even if boys still outnumber girls in all education institutions, the rate of increase of girl students are higher than that of boy students. Accordingly women are given more opportunity than ever for the employment vis-a-vis men. The number of employed women has been increasing greatly in recent years inproportion to the acceleration of industrialization. The type of their job is also various and colorful ranging from factory worker to doctor and lawyer. There are some problems to be solved with respect to the improvement of women's education. The improved women's education should be reviewed light of the fact that inequality still exists between men and women in occupation and wages, and that women is required of good education contributable to the better Korean society.

The purpose of this study is to verify the effect of forming groups according to the brain hemisphere preference on the cooperative problem solving learning achievement in the middle school technology. The subjects of this study were 95 second grade boy students of a middle school in Daejeon and the measurement instrument of the left and right hemisphere preference is the Brain preference Indicator(BPI) which had been developed by Torrance et al(1977) and was adjusted by Ko, Younghee(1991). The academic achievement was analyzed on cognitive, psychomotor and affective domains. Derived results from this research are stated below: First, making groups according that the brain preference is more similar was more effective than making groups according to the high familiarity and the similarity of performance in the academic achievement of psychomotor and affective domains. Second, making groups according that the brain preference is more similar was more effective than making groups according that the brain preference is more diffrent for the academic achievement of affective domains on the cooperative problem solving learning in technology. Third, the academic achievement score of the right hemisphere preference group is higher than the score of the population in three domains. Also, the academic achievement score of the right hemisphere preference group is higher than the score of the left hemisphere preference group.
