The topic of homicide is important for our society, since it is a major public health problem And sexual homicide is related to human instincts of sexuality and aggression In Korea, these cases are less pravelent than any other countries, but are increasing according to rapid progress of social change and globalization. The psychological study of sexual homicide is necessary for the scientific investigation(e.g. criminal personality profiling) and prevention of homicide. This study is aimed at reviewing foreign research and finding ways of putting those ideas to empirical test in our country. And this topic will be dealt in both of discriptive and psychodynamic approaches. One important area for prevention involves early identification and intervention with formative traumatic events. It should be noted that many of these killers come from homes where there was a great deal of physical, sexual, and emotional abuse in the childhood The unresolved question is why such earlier abuse leads to an outcome of a sexual homicide in only a few individuals when child abuse wears so much more prevalent. Perhaps if there were opportunities to study and treat these individuals over a prolonged period of time, more answers would be available. In this study it is essential to unravel how the killer's sting out of sexualized fantasies and conflicts occurs, in other words, how the urge to act on the fantasies in some form eventually breaks through the perpetrator's ego defences, with diverse outcomes.

E-TEK 전극(20% Pt/C, 0.4 ㎎ Pt/㎠)과 Nafion # 115 이온교환막을 사용한 반응면적이 50 ㎠인 단위전지를 세 개와 다섯개로 접합하여 폴리머 전해질형 연료전지 스택을 구성하고 이에 대한 성능을 조사하였다. 직-병렬 가스 유로의 흑연 양극판이 Z-pattern 양극판에서 얻은 실험결과 보다 스택의 성능이 우수하게 나타났다. 다양한 밀봉방법과 재료를 이용하여 가스 누출 방지 및 가압실험을 하였다. 가스켓이 없는 밀봉방법인 O-ring을 사용한 양극판으로서 이러한 실험목적을 달성할 수 있었다. 반응면적 50㎠을 갖는 5-cell 스택은 자동온도 70℃, 작동 압력 3bar에서 0.7 V, 350㎃/㎠을 나타내었다. 이 스택은 1000시간 이상의 운전에서도 눈에 띄는 성능 저하 현상이 나타나지 않았다. Individual cells having 50 ㎠ active area were fabricated using E-TEK electrode(20% Pt/C, 0.4 ㎎ Pt/㎠) and Nafion # 115 membrane. PEFC stacks having three and five cells were assembled without cooling plate and its performance was investigated. Graphite bipolar plates of series-parallel gas flow channel exhibited better stack performance compared to that obtained for Z-pattern plates. Various sealing methods and materials have been bested to prevent gas leakage and to enable pressurization. The use of O-rings instead of gaskets in the bipolar plates was proposed as the appropriate sealing method. 5-Cell stack of active area of 50 ㎠ showed the performance of 0.7 V and 350㎃/㎠ at the operating temperature and pressure of 70℃ and 3 bar respectively. This stack didn't show any appreciable performance degradation even after more than 1000 hours of operation.
