이규성,김문희 한국운동과학회 2002 운동과학 Vol.11 No.1
이규성, 김문회. 탄력밴드운동시시 NIDDM 환자의 혈장내 Leptin 수준과 Insulin, Glucose 및 신체구성성분과의 관련성을 분석. 운동과학, 제11권 제1호, 131-143, 2002. 이 연구는 탄력밴드 운동시 NIDDM환자의 혈장내 Leptin 수준과 Insulin, Glucose 및 신체구성성분과의 관련성 분석하고자 하는데 있다. 연구대상은 00시에 거주하는 제 2형 당뇨 비만노인여성환자 (체지방량이 30% 이상)로 저항성-밴드 운동군(exercise group) 9명, 통제군 (control) 10명으로 총 19명을 대상으로 하였다. 운동프로그램은 저항성 밴드 트레이닝 운동으로 총 12주간 실시하였으며, 초기단계는 7종목, 둘째 단계는 9종목, 세번째 단계에서는 11종목으로 구성하였다. 운동강도는 밴드를 늘린 길이 즉, 저항력에 따라 분류하는데 노인 여성인 점을 감안하여 주로 노랑색 (thin; 20㎝ -0.7㎏, 40㎝ - 1.0㎏, 60㎝ 1.1㎏의 저항력) 과 적색(medium; 20㎝ - 0.9㎏, 40㎝ - 1.6㎏, 60㎝ 2.0㎏의 저항력)을 이용하였다. 운동빈도는 주당 3∼4일로 운동시간은 총 65분 정도로 2∼3set씩 실시하였다. 자료처리 방법은 12주간의 저항성-밴드운동이 제2형 당뇨 노인여성의 집단간, 기간간의 혈청 leptin, insulin, glucose, NEFAs수준 및 신체구성성분의 차이를 알아보기 위해 반복측정에 의한 이원변량분석을 실시하였으며, 운동후 6주와 12주후에 leptin, insulin, glucose, NEFAs수준 및 신체구성성분과의 관련성을 의해 Pearson의 상관분석을 실시하였다. 이 연구결과 집단별 (운동여부), 기간별 (사전, 6주후, 12주후)에 따른 OGTT 결과, 운동군에서 훈련 6주후에 근육내 uptake 비율이 약간 높아진 것으로 나타났으며, 혈청 렙틴, 인슐린과 NEFAs수준는 운동군에서 운동기간이 지남에 따라 감소하는 것으로 나타났다. 또한 leptin과 insulin, glucose, NEFAs수준 및 신체구성성분과의 관련성을 살펴본 결과 렙틴은 체지방량과 NEFA가 높은 관련성이 있는 것으로 나타났다. 이러한 결과는 12주간의 저항성 밴드 트레이닝이 저항성 운동임에도 불구하고 NIDDM 노인환자의 렙틴 수준, 인슐린, NEFAs 수준을 감소시킨 결과를 가져와 지질대사를 향상시키고, 체중 감소를 유도하는 운동으로서 적절하다는 활용 가능성을 확인케 하였다. Lee, K.S., Kim, M.H. The Analysis of Relationships on Plasma Leptin and Insulin, Glucose Levels and Body Composition in Obese Women with NIDDM during Band Training. Exercise Science, 11(1): 131-143, 2002. To evaluate analysis of relationships on plasma leptin and insulin, glucose levels and body composition 20 obese subjects with NIDDM were enrolled in 12 weeks of band-resistance training. The training program consisted of band exercise for 40min at least 5 times per week, with the intensity of exercise maintained at 50% of 1RM. Serum leptin levels decreased significantly in the exercise training group (p<.05), but not in the sedentary group. Body weight and percentage body fat decreased in the exercise training group, but not in sedentary group. However, The concentrations of plasma insulin and NEFAs did not differ between the groups either before or after exercise training. This study demonstrates that band-resistance training in obese women with NIDDM subjects reduces serum leptin levels dependent of changes in body fat mass during 12 weeks of band-resistance training
Electrochemical Synthesis of Ammonia in Ambient Condition Using Various Phase of Copper Sulfide

Ammonia is one of the most commonly synthesized chemicals in the world. However, most ammonia is synthesized through the Harber-Bosch process which consumes 1-2% of global energy because of its high temperature and pressure condition. Electrochemical synthesis of ammonia through nitrogen reduction reaction(NRR) in ambient condition enables to lessen the energy consumption. NRR is also important in hydrogen storage because ammonia is easily liquefied by compression and it has a high hydrogen density. So that NRR facilitates the utilization of hydrogen by lessening the energy consumption and the scale of facilities. Various metal sulfides has been studied as the candidates for NRR catalyst. Among the various metal sulfides, copper sulfide is one of the most prominent candidate for NRR catalyst because of its low cost and good catalytic activity. In this work, various phases of copper sulfide were synthesized and investigated the possibility of NRR catalyst.

Background and Objectives Respiratory scoring guidelines for children and adults havebeen used for evaluating adolescents both in the 2007 and 2012 American Academy of SleepMedicine (AASM) scoring manuals. We compared the scoring methods of polysomnographyused in these scoring manuals, where pediatric and adult scoring rules were adopted for thediagnosis of sleep apnea in adolescents. Subjects and Method 106 Korean subjects aged between 13 and 18 years were enrolled. All subjects underwent overnight polysomnography in a sleep laboratory. Data were scored accordingto both pediatric and adult guidelines in the 2007 and 2012 AASM scoring manuals. Results Both pediatric and adult apnea hypopnea index (AHI) using the 2012 method weresignificantly higher than those using the 2007 method. The difference in AHI compared betweenpediatric and adult scores with the 2012 AASM scoring system was markedly decreasedfrom that with the 2007 method. There was a significant discordance in sleep apneadiagnosis between pediatric and adult scoring rules in the 2012 method. Conclusion Both pediatric and adult rules were used for the diagnosis of adolescent sleep apneain the 2012 method. However, there was significant discordance in the diagnosis betweenpediatric and adult scoring guidelines in the 2012 AASM manual, probably due to differentcut-off values of AHI for the diagnosis of sleep apnea in pediatric (≥1) and adult (≥5) patients. Further studies are needed to determine a more reasonable cut-off value for the diagnosis ofsleep apnea in adolescents.
