Objective : To correct apical vertebral rotation for adolescent idiopathic scoliosis (AIS), direct vertebral derotation (DVD) or simple rod rotation (SRR) might be considered. The aim of the present study is to introduce the surgical experiences of AIS by a Korean neurosurgeon and to evaluate the effectiveness of SRR for apical vertebral rotation. Methods : A total of 9 patients (1 male and 8 females) underwent scoliosis surgery by a neurosurgeon of our hospital. The Lenke classifications of the patients were 1 of 1B, 2 of 1C, 1 of 2A, 1 of 2C, 3 of 5C and 1 of 6C. Surgery was done by manner of simple rod rotation on the concave side and in situ coronal bending. Coronal Cobb's angles, vertebral rotation angles and SRS-22 were measured on a plain standing X-ray and CT before and after surgery. Results : The mean follow up period was 25.7 months (range : 5-52). The mean number of screw positioning level was nine (6-12). The mean age was 16.4 years (range : 13-25) at surgery. The mean Risser grade was $3.7{\pm}0.9$. The apical vertebral rotation measured from the CT scans was $25.8{\pm}8.5^{\circ}$ vs. $9.3{\pm}6.7^{\circ}$ (p<0.001) and the Coronal Cobb's angle was $53.7{\pm}10.4^{\circ}$ vs. $15.4{\pm}6.5^{\circ}$ (p<0.001) preoperatively and postoperative, respectively. The SRS-22 improved from 71.9 preoperatively to 90.3 postoperatively. There were no complications related with the operations. Conclusion : SRR with pedicle screw instrumentation could be corrected successfully by axial rotation without complications. SRR might serve as a good option to correct AIS deformed curves of AIS.

The purpose of this study was to investigate the effect of personal, familial, educational, internet factor on adolescent's self-esteem according to the age and gender. The participants were 2,229 male and female students attending to middle and high schools. The results of this study were as follows: First, the self-esteem score of middle school students was higher than the score of high school students. Second, there were differences between females and males in several aspects. In order to explore and identify patterns of these differences, hierarchical multiple regressions were conducted with separate groups (male middle school students, female middle school students, male high school students, and female high school students). Third, female middle school students' self esteem was affected by familial and educational factors. Male middle school students' self esteem was affected by familial factor, particularly by parental marital conflict. In the case of female high school students, self esteem was associated with economic variables (spending money and subjective economic level). Male high school students' self esteem was affected b? the level of use of the internet.

This study was done to compare nutrient intakes, anthropometric indices, and psychosocial factors related to smoking by smoking status among adolescent girls in Seoul. Subjects were high school students, and smokers were 17.6%. Nutrient intakes were analyzed by convenient method, and anthropometric measurements were done by Inbody 2.0. Psychosocial factors of smoking were examined based on the Theory of Planned Behavior : 26 attitudinal, 9 normative, and 17 control beliefs were used. Smokers smoked 5-7 cigarettes a day on average, with 1.26 pack-years of smoking, There were no significant differences in anthropometric characteristics, except fat distribution, between smoking(n=92) and nonsmoking(n=92) and nonsmoking(n=94) group. The percentage of alcohol groups. Especially, caloric intake (63.6% of RDA) were much below the recommended level. With respect to psychosocial factors, 18 out of 26 attitudinal beliefs were significantly different between smokers and nonsmokers. Smokers responded less negatively on the items of bad health effects of relax(p<0.001). In addition, smokers were more convinced of advantages of smoking (test, etc.)but responded less negatively on the disadvantages of smoking(bothering others, yellow teeth, bad breath, etc.). Smokers expressed less pressure for not smoking from siblings, friends, school seniors than nonsmokers. In addition, smokers, expressed less confidence in controlling the urge to smoker or quitting smoking in several situations, such as 'after a meal', 'feel bored', 'with friends', 'when angry' offered a cigarette by friends', 'drinking coffee or tea', 'drinking alcohol', 'seeing others smoke'(p<0.001). Smokers also felt less developing in applying specific skills for controlling the urge to smoker or quitting smoking. These findings suggest the need for developing smoking cessation programs for adolescent females, focusing on specific beliefs identified in this study.

The purpose of this study is to survey the prevalence of obesity assessed on the basis of height and weight among students in primary and secondary schools in the metropolitan area of Seoul, Korea during the period of 1979 to 1996. The major findings are as follows ; 1) The fiftieth percentile values of BMI have increased more in mid-ranged age group than upper(16-17 years old) and lower(6-7 years old) ranged age groups. 2) The prevalence of obesity by standard weight of height was higher among male students than female students and students in the primary schools showed higher weight increase than adolescent age(12-17 years old) group. As a whole, the prevalence of obesity over last 18 years has increased 4.6 times in males and 3.2 times in females. 3) Judged on the basis of the BMI 90th, 95th percentile values of 1979 , the prevalence of obesity among male students showed higher increases than among female students. Higher increase was also observed among primary school students than among middle and high school students. Increase of weight was higher for the $\geq$95th percentile group than the 90-95th percentile group. 4) Judged on the basis of the BMI, 90th, 95 th percentile values of NHANES-I, the $\geq$95th percentile group showed higher increase in the prevalence of obesity than the 90-95th percentile group. According to the 1996 data, severe obesity group ($\geq$95th percentile) was about two times of NHANES-I in male primary school students, while the number for female middle and high school students was about 1/5 of NHANES-I.

This study was undertaken to compare the obesity related dietary factors among rural middle school students living in the Daegu.Kyungbuk area. Anthropometric data showed that mean height and weight were 162.7$\pm$8.6cm and 53.9$\pm$9.8kg in 220 male students and 158.4$\pm$6.2cm and 51.0$\pm$7.6kg in 210 female student. Mean BMIs for boys and girls were 19.00$\pm$2.35 and 19.30$\pm$2.45, respectively. 71.36% of male students and 71.9% of female students were underweight by the BMI index. Students who skipped the breakfast were up to 66.8%. The reasons for skipping a meal for both sexes were significantly different. Compared to males, more female respondents felt guilty and depressed related to eating. Furthermore, females were more significantly concerned about body image, diet and body weight (p<0.001), and they were not satisfied with their weight. The sources of information on obesity and diet were radio and TV in males, while females gathered information from magazines and friends. The ideal body weight of male students was heavier than the actual body weight while female students desired a thinner body shape. In conclusion, a different approach for nutrition education based on sex should be developed, and implemented fur adolescents.

Purpose: This study aimed to assess the reference values and factors influencing blood lead levels among Korean adolescents. Methods: The study population consisted of 1,585 adolescents (801 males, 784 females; aged 10-19 years) who participated in the Korea National Health and Nutrition Examination Survey 2010-2013. We analyzed blood lead concentrations in relation to demographic/lifestyle characteristics for all participants. "Reference values" of blood lead levels were calculated as the upper limit of the 95% confidence interval of the 95th percentile. Results: The average "reference value" for blood lead concentrations among Korean adolescents was $2.25{\mu}g/dL$ ($2.49{\mu}g/dL$ for males, $2.07{\mu}g/dL$ for females), and the geometric mean of the blood lead concentrations was $1.34{\mu}g/dL$. Males had higher blood lead concentrations than females (male, $1.48{\mu}g/dL$; female, $1.19{\mu}g/dL$; P<0.001). Elementary school students had higher blood lead concentrations than junior and senior high school students ($1.44{\mu}g/dL$ vs. $1.31{\mu}g/dL$, P<0.001). Participants living in detached houses had higher blood lead concentrations than those living in apartments (P<0.001) and current smokers had higher concentrations than nonsmokers or participants with secondhand smoke exposure (P<0.05). Additionally, participants with excessive alcohol consumption had higher levels than non-drinkers (P<0.001). Conclusion: This study provides national reference data on blood lead concentrations stratified by demographic and lifestyle factors among Korean adolescents. Further studies are needed to elucidate the relationship between increased lead exposure and demographic factors including type of housing.

The purpose of this study is to identify health problems and health behaviors of the middle-aged residing in urban areas and to plan and implement health promotion programs based on their health needs. The subjects' age ranged from 30-64 years in 1.040 middle-aged residing in an area of Kangbook-ku in Seoul. The data were collected from September 1998 to February 1999 with structured questionnaire using face-to-face or telephone interviews. The data were analyzed by SPSS-PC+ and identified by $X^2$ test and ANOVA. The results were as follows: 1. 35.4% of the males and 27.8% of the female responded that they were healthy regarding their perceived health status. In the order of chronic illness prevalence in the case of males was hypertension, diabetes, and digestive disorders and. in the case of females, was digestive disorders, hypertension, arthritis, anemia, and diabetes. 2. Male and female's smoking rates were 7.3% and 3.6% each and marked the highest rate of 30 to 40 years: drinking behavior was 66.9% in males and 32.2% in females. 3. The younger males had the worse dietary habits and had the lowest frequency of regular exercise. The older the females were, the more their weight increased. According to the results, health promotion programs by sex are recommended, especially in the target population of 30 to 40 years. and focused on the strategies for promoting self-care and actual health practice: it is strongly suggested that health promotion programs for adolescent and school-aged children before middle aged health behavior begins.

연구목적 최근의 신경영상 연구들은 주요 우울장애의 기전을 인지 회로와 감정 회로 연결의 기능장애 즉, 후외방 전두피질과 전전두엽을 번연계로 연결하는 전측대상피질의 연결성 장애에 초점을 맞추고 있다. 소아청소년 주요 우울장애에서 확산텐서영상(diffusion tensor image, DTI)을 사용한 종전의 연구들은 양측 구상회속, 양측 하측 전두후두속, 좌측 전측대상피질, 좌측 상종속 등에서 신경연결의 감소를 보고하였다. 이 연구에서 우리는 정신과적 투약력이 없는 초발 주요 우울장애 청소년에서의 신경 연결성을 DTI를 이용하여 정상 대조군과 비교하였다. 방 법 고려대학교 구로병원을 내원한 청소년 환아들 중 정신과적 투약력이 없으며 주요 우울장애를 처음으로 진단받은 환아들(n=26, 남성 10명, 여성 16명) 및 대조군(n=27, 남성 5명, 여성 22명)을 모집하였다. 정신과적 면담, 지능지수, 해밀턴 우울척도를 포함한 심리검사, 확산강조영상을 포함한 MRI 검사가 항우울제 투약 전에 시행되었다. Fractional anisotropy(FA), radial diffusivity, mean diffusivity, axial diffusivity가 DTI를 사용하여 계산되었다. 통계적 분석을 위해 FMRIB Software Library-Tract Based Spatial Statistic가 사용되었다. 결 과 전체 뇌의 분석에서는 유의한 구조적 변화를 관찰할 수 없었다. 그러나 관심영역을 지정하여 시행한 분석을 하였을 때, 환아군에서 대조군에 비해 우측 상종속 부위에 유의미한 FA값의 감소를 보인 3개의 다발이 관찰되었다. 결 론 주요 우울장애를 진단받은 청소년 환아군에서 대조군에 비해 DTI에 기반하여 우측의 상종속에 연결성 감소를 보였다. 따라서 DTI를 통한 구조적 연결성은 정신과적 투약력이 없는 초발 주요 우울장애 청소년에서도 생체 표지자로 사용될 수 있을 것이라 생각된다.
