The purpose of this study was to investigate the effects of parent's nutritional education for body weight control of obese children. The weight control program include nutritional education, exercise and behavioral therapy during 20 weeks. Twenty- three children completed this program, the children were divided into two groups by control group and parent's nutritional education group. Parents volunteered to participate in a 4 week nutritional education program for parents and contact the therapist at least once per week to help their obese children. The results from this study were as follows. There were not significant differences in anthropometric values after weight control program between two groups. Triglyceride(TG) level in serum was decreased after weight control program in group of parent's nutritional education, but there was not significant difference. Parent's nutritional education did not add improvements in weight and fitness, but the children of parent's nutritional education group showed increased general self-worth upon completing the program(p<0.05) whereas the other children of control group did not. Also there were desirable changes of exercise and life habits in group of parent's nutritional education group.

Nano Cu powders, synthesized by Pulsed Wire Evaporation (PWE) method, have been compacted by Magnetic Pulsed Cojpaction(MPC) method. The microstructure and mechanical properties were analyzed. The optimal condition for proper mechanical properties with nanostructure was found. Both pure nano Cu powders and passivated nano Cu powders were compacted, and the effect of passivated layer on the mechanical properties was investigated. The compacts by MPC, which had ultra-fine and uniform nanostructure, showed higher density of 95% of theoretical density than that of static compaction. The pur and passivated Cu compacted at exhibited maximum hardnesses of 248 and 260 Hv, respectively. The wear resistance of those compacts corresponded to the hardness.

본 연구는 한국시장에 진입한 일본기업들을 대상으로 진입방식 선택 결정요인을 분석하였다. 즉 합작투자 혹은 라이센싱을 선택케 하는 요인들이 무엇인지를 거래비용 특성요인, 환경적 특성 요인, 전략적 요인, 그리고 기업 특성 요인으로 구분하여 조사하였다. 합작투자 55개 기업과 라이센싱을 선택한 24개 기업들을 대상으로 로짓분석을 실시하여 다음과 같은 연구결과를 얻었다. 거래비용 특성 중에서 파트너의 기회주의 속성이 높을수록, 그리고 전략적 요인 중에서는 현지시장의 전략적 중요성이 높을수록 라이센싱 보다는 합작투자를 선택하는 것으로 나타났다. 반면에 환경적 특성 중에서는 현지시장의 수요 물확실성이 높을수록 합작투자 보다는 라이센싱을 선택하는 것으로 밝혀졌다. 마지막으로 기업 특성 중에서는 모기업의 국제영업 경험이 있는 기업들이 합작투자를 선택하며, 모기업의 규모는 진입장식의 선택에 영향을 미치지 않는 것으로 드러났다. 초록(외국어)

The electrodes were fabricated by compounding the commercial activated carbons and additives of conducting polymer with PVdF mono binder and PVdF-PVP mixed binders. The best performance of the electrodes fabricated with activated carbon(BP-20) and PVdF-PVP mixed binders showed in 88wt. ％ BP-20. 7wt. ％ conducting polymer and 5wt.％ PVdF-PVP mixed binder. The electrode exhibited excellent electrochemical characteristics having 8.16 W.h/kg of energy density, 34.77 F/g of specific capacitance, 0.67Ω of ESR.
