The subjects in this study consisted of 180 elementary school children and 120 middle school students: 30 boys and 30 girls in each 4th, 5th, 6th grade of elementary school, and 1st, 2nd grade in middle school, totally 150 boys and 150 girls. % body fat was measured by means of bioimpedance analysis. The subject were controlled to be prohibited one-way ANOVA and Duncan's multiful range test with SPSS/PC program. From this study we could find the results as follows: 1. The mean % body fat in 4th grade elementary school children appeared 18.76%±5.13 in boys, 21.24±4.11 in girls. Over-fatty boys(above 20% BF) were 35%, Over fatty girls(above 25% BF) were 16.7%. 2. The mean % body fat in 5th grade elementary school boys and girls appeared 18.11%±4.05, 21.44±4.30 respectively. Over-fatty boys and girls were 30%, 20% respectively. 3. The mean % body fat in 6th grade elementary school boys and girls appeared 17.93%±4.02, 21.87±3.38 respectively. Over-fatty boys and girls were 23.3%, 16.7% respectively. 4. The mean % body fat in 1th grade middle school boys and girls appeared 16.72%±5.46, 23.71±2.68 respectively. Over-fatty boys and girls were 26.7%, 36.7% respectively. 5. The mean % body fat in 2th grade middle school boys and girls appeared 15.24%±4.46 in boys and 23.08±33.33 in girls. over-fatty boys and girls were 6.7%, 30.0% respectively. 6. The difference of mean % body fat between boys and girls appeared to be statistically significant at each grade.(p.<05) 7. The difference of mean % body fat between 2nd grade middle school boys and 4th, 5th, 6th grade elementary boys showed statistical significance.(p.<05) The difference of mean % body fat between 1st grade middle school girl and 4th, 5th grade elementary girls showed statistically significance.(p.<05) With the results above we could recognise that current % body fat in elementary children and middle school girl were high and the percentage of over-fatty boys and girls was also high. This means that nowadays appropriate balance between caloric intake and consumption becomes more important for boys and girls. But the trend of body fat change appearde normally. For both boy and girl, the 1st grade of middle school was to be thought as the turning point of % body fat; for boy decreasing and for girls increasing. This was to be reliable, because in that period the effect of hormonal function becomes very active.

강현식, 하창덕, 홍혜련, 권훈겸, 김성희, 우상구. 여자 초등학생의 신체활동량 및 강도와 심폐체력, 신체구성, 심혈관 위험인자와의 상관성. 운동과학, 제20권 제4호. 389-396, 2011. 본 연구의 목적은 기존의 횡단적 연구에서 비만 및 대사증후군의 예방 및 치료를 위해 제시된 13,000보수의 적정보수를 목표로 12주간의 신체활동 중재를 실시한 후, 신체활동량 및 강도와 심폐체력, 비만지표, 심혈관 위험인자의 상관성을 검증하는 것이었다. 본 연구의 대상자는 초등학교 여학생24명(11.79±0.78세)으로 하였고, 12주 신체활동 중재 전과 후에 신장, 체중, 체질량지수, 체지방율, 허리둘레, 최대산소섭취량, 중성지방, 총 콜레스테롤, 고밀도지단백 콜레스테롤, 혈당을 측정하여 분석하였으며, 12주간 1일 13,000보수의 신체활동을 하도록 권고하였다. 연구결과, 12주간의 신체활동 중재를 통해 신장, 체중, BMI, 심폐체력의 유의한 증가가 있는 것으로 나타났다. 신체활동량과 신체구성, 심폐체력, 심혈관질환 위험인자와의 상관성 분석 결과, 신체활동량은 최대산소섭취량과 수축기혈압과 유의한 상관성이 있는 것으로 나타났다. 신체활동 강도와 신체구성, 심폐체력, 심혈관질환 위험인자와의 상관성 분석 결과, 신장과 중강도 및 고강도 신체활동이 상관성이 있는 것으로 나타났다. 결론적으로 초등학교 여학생의 경우 심폐체력증진과 키 성장 자극 그리고 비만 및 심혈관질환 위험인자의 효과적인 개선을 위해서는 중등도 이상의 규칙적인 운동을 포함하여 상당한 수준의 신체활동량(예, 1일 13,000보수)이 필요하다는 사실을 의미하는 것으로 판단된다. Kang, H. S., Ha, C. D., Hong, H. R, Kwon, H. K., Kim, S. H., Woo, S. K. Correlations of physical activity with cardiorespiratory fitness, body composition, and cardiovascular risk factors in elementary school girls. Exercise Science. 20(4): 389-396, 2011. The purpose of current study was to investigate the correlations of physical activity with cardiorespiratory fitness (CRF), body composition, and cardiovascular risk factors in elementary school girls. A total of 24 girls (11.79±0.78 years) voluntarily participated in the physical activity intervention stuy. Before and after the intervention, all the participants underwent a series of measurements including body composition, obesity indices, CRF, and cardiovascular risk factors. Then each participant was invited to participate in a physical activity intervention targeting at 13,000 steps/day, which was predetermined in our preliminary study, for 12 weeks. All participants worn the Life-corder accelerometer to monitor their daily physical activities including its volume and intensity. Height, weight, body mass index, CRF were increased significantly after the 12-week PA intervention. PA volume was positively related to CRF and systolic blood pressure (SBP). Moderate and high PA intensities were positively relate to height growth. In conclusion, the current findings of the study suggest that substantial amount of physical activity (i.e., accumulated 13,000 steps per day) including regular exercise with moderate or higher intensities would be necessary for the improvements of in CRF, obesity indices, and cardiovascular risk factors as well as height growth.

Nasobiliary catheter drainage was first introduced a decade ago. It provides drainage of the biliary system and facilitates interventional procedures of the biliary and pancreatic system, both for therapy and research purposes. 1) ENBD was successfully performed in 81 out of 84 (95.3%) patients with biliary and pancreatic disease. 2) The indication of ENBD in our patients was for acute suppurative cholangitis (n=25), prevention of stone impaction after EST (n=22), gallstone pancreatitis (n =12), ESWL of bile duct stones (n=15), overt stone impaction (n=7), benign bile duct stricture (n=3), malignant bile duct stricture (n=15), drainage of pancreatic pseudocyst (n=1) and pancreatic duct stone (n=1). 3) All the patients, who received ENBD successfully, sihowed improvement of liver function and general condition. 4) The complication of ENBD was cholangitis in 3 patients and dislodgement of tube in another 3 patients. In conclusion, we believe that nasobiliary catheter should be appled more frequently during endoscopic manipulation of the biliary and pancreatic system and that the technique of insertion should become an essential part of training in ERCP.

A novel composition of ginsenosides with high Rd and Rg3 content, UG0712 was evaluated for exercise capacity, and post-exercise fatigue recovery through in vivo treadmill maximum running test (MRT) under continuous training (n=9) or resting (n=10) conditions of the SD rats. The standardized ginseng root extract (UG0714) was used for efficacy comparison. Each animal was treated orally at the dose of 25 ㎎/ ㎏ for 8 weeks in exercise group or 9 weeks in resting group. Blood lactate dehydrogenase (LDH) activity and lactic acid concentration were measured to evaluate the post-exercise fatigue recovering effect after exhausted exercise. MRT of UG0712 group showed statistically significant 27.8% increase at week two (P<0.05) and maintained at an increased level in 8-weeks (27.6% increase, not significance) compared with vehicle treated control group. In resting group, MRT of UG0712 after 8-weeks treatment showed 23.0% increase compared with vehicle group (P<0.05) and 23.5% increase when compared with UG0714 group (P<0.05). While no significant changes were found in UG0714 group under either exercise or resting conditions. UG0712 group showed significantly decreased blood LDH levels compared with both vehicle (P<0.01) and UG0714 (P<0.05) groups under trained condition but no significant changes in resting condition. In addition, UG0712 significantly decreased blood lactic acid levels in trained (P<0.01) group, while UG0714 showed no significant changes. Considering the evaluation results from both exercise capability and post-exercise fatigue recovery status, it can be concluded that administration of a standardized Rd and Rg3 ginsenoside composition, UG0712 improves endurance exercise performance probably via increased aerobic energy metabolism, and accelerated post-exercise fatigue recovery.
