Objectives : This study was carried out in order to contribute to preventing dental caries, which is the biggest disease in adolescence and to promoting oral health by implanting a right habit on oral care targeting adolescents, and further to offer basic help to proceeding with making the better health life. Methods : This study carried out questionnaire survey targeting 1,100 students of middle schools where are located in small and medium-sized cities of Gyeongnam from March 7-18, 2011. Statistical processing was performed frequency analysis and cross tabulation, by using SPSSWIN 12.0 program. Results : As for middle school students' oral health education experience, the group with educational experience was indicated to be 52.9% for girl students and 47.1% for boy students(p<.05) in case of gender. Toothbrushing time was indicated to be the highest with 25.6% in 'after having breakfast'. The appearance of toothbrushing after having lunch at school was indicated to be 53.3% for girl students and 26.3% for boy students(p<.001) by gender. The most important reason for toothbrushing accounted for 82.1% in the 1st grade, 71.1% in the 2nd grade, and 67.4% in the 3rd grade depending on school year as for the response as saying of 'aiming to prevent decayed tooth and gum disease.' Thus, the lower school year led to having indicated to be higher in response as saying of brushing teeth for preventing decayed tooth and gum disease(p<.001). As for a toothbrushing method by gender, boy students accounted for 24.2% in response as saying of 'brushing teeth freely', thereby having been indicated to be higher than 15.0% for girl students(p<.001). Conclusions : In order for toothbrushing method to be rightly practiced and habituated continuously, there will be a need of changing adolescents' awareness and of being driven systematically and continuously through oral health education.

Angiokeratomas represent vascular lesions and are histologically characterized by superficial dermal vascular ectasia with overlying epidermal hyperkeratosis. Angiokeratoma circumscriptum is one of five types in the group of the angiokeratomas. The lesion is present from birth but may appear in childhood or adulthood. Angiokeratoma circumscriptum is typically hyperkeratotic papules or nodules situated unilaterally on the foot or distal aspect of the leg, but can occur elsewhere on the body. Isolated tongue involvement is very rare. We report a 12-year-old boy with angiokeratoma circumscriptum of the posterior dorsal tongue with a review of the literatures.

The total population of Korea in 1975 was 35,281,000 and population density was $357/km^2$, which is one of the highest rate of the countries in the world. In the early part of 1960's, prior to the initiation of national family planning program in 1962, the natural population increase rate in Korea was almost 3.0%. However, due to the positive support and activity of the national family planning program, the population growth rate has been dropped right below 2.0% in 1970, and decreased to 1.7% in 1975. The average number of children per woman was 5.8 in 1961 and has decreased steadily to 3.5 in 1975. However, traditional value like the 'boy-preference' concept may bring many difficulties of lowering the fertility rate, decreasing number of children less than three in the future. Rising marriage age which had much contributed to decrease the population growth showed preferably falling trends since 1970. There is a prospect that total number of birth will be continuously increased while the fertility rate may be fallen since the age group born during 'baby-boom' soon after the Korean war are becoming the reproductive age group at present time. Considering the above mentioned factors, family planning program should be much improved and strengthened and the government support is much required in order to meet the above mentioned objectives which maintain appropriate level of the population growth.

This study examined different individual and environmental factors that affect children's game addiction tendency. As individual variables, game user' motivation, self-control, and self-esteem were included in the analysis. As family variables, communications with mothers, parental control of children's computer use and parental internet use were examined, as school variables, school adjustment and teacher's supervision of children's computer use, and as peer variables, peer group's attitude toward computer games were used. The sample consisted of 994 fifth and sixth grade children. Statistics and methods used for the data analysis were Cronbach's alpha, frequency, percentage, two way ANOVA, Pearson's correlation and Hierarchical Regression. Several major results were found from the analysis. First, boys were addicted more than girls. No difference was found in the addiction tendency between the 5th graders and the 6th graders. Second, game users' motivation, that is, their interest-amusement motive, avoidance motive and aggressive motive, had a positive correlation with their game addiction tendency. However, self-control and self-esteem had a negative correlation with children's game addiction tendency. Third, problematic communications with mothers and parental control of children's computer use had a positive correlation with children's game addiction tendency. Open communications with mothers had a negative correlation with children's game addiction tendency. Fourth, school adjusaent had a negative correlation with children's game addiction tendency. And peer group's attitude towards computer games had a positive correlation with children's game addiction tendency. Fifth, low self-control, peer group's attitude towards computer games, children's interest-amusement motive, avoidance motive, aggressive motive, school lesson adjustment, parental control of children's computer use and school nile adjustment were important predicting variables of boy's game addiction tendency. Avoidance motive, low self-control, interest-amusement motive, peer group's attitude towards computer games, and parental control of children's computer use were important predicting variables of girl's game addiction tendency.

Within the group of congenital cardiac anomalies manifesting atrioventricular discordance, there exists a subset of hearts characterized by the additional presence of double outlet of the morphological right ventricle. Most of these hearts have associated pulmonary stenosis and abnormal direction of the cardiac apex, and all have a ventricular septal defect. Recently, a 10-year old boy underwent successful surgical correction of double outlet right ventricle with atrioventricular discordance. Diagnostic confirmation was made by 2-D echocardiography, cardiac catheterization and cineangiocardiography. The operation consisted of patch closure of ventricular septal defect so as to leave both great arteries draining the systemic[morphologically right] ventricle, and insertion of an extracardiac valved conduit between the morphological left ventricle and the distal end of the proximally oversewn pulmonary artery. Postoperative course was uneventful.
