As a consequence of increasing crime rates, there is also a growing interest in crime prevention strategies. Research on the spatial distribution of fear of crime may contribute to a better understanding of these phenomena. In order to involve the results of those researches in design practice in a systematic way, some environmental design concepts influencing fear of crime may be useful. In this paper we present four basic concepts of such factors to reducing fear of crime. They are sence of community, controlling circulation, surveillance, and image. In addition, a field project is tested on these factors.

Body temperature is controlled by thermoregulatory center of the hypothalamus. We report a case of 24 years old man with central fever. He was subjected to a partial excision of pituitary tumor compressing optic chiasm four years ago. He has received hormonal therapy for panhypothyroidism after removal of pituitary tumor. And He received gamma knife operation for partially contrast-enhancing masses in suprasellar and both hypothalamic areas that is probably postoperatively remnant or recurrent tumor of pituitary adenoma. One year after gamma knife operation, he presented with a febrile syndrome of unknown origin including rhabdomyolysis. All usual investigations proved negative. We diagnosed him as central fever with rhabdomyolysis. He received medical ICU care with cooling bed, ice pack. And his symptom improved. Postoperative hyperthermia may result following resection of the pituitary tumor. When central fever is suspected taking note of past history, a quick recognition of course of fever can help reduce the using of unnecessary antibiotics and hospital stay.

페그인터페론과 리바비린 병합요법은 만성 C형 간염의 일차 치료법이다. 저자들은 만성 C형 간염 환자에서 페그인터페론 과 리바비린 병합 요법 중에 발생한 벨마비 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 5년 전부터 만성 C형 간염을 앓아온 48세 남자이며, PEG-IFN α-2a 135μgm 피하주사 주1회와 하루 1200㎎의 리바비린을 투여하였다. 치료시작 후 9개월째 환자는 오른쪽 안면의 근력약화를 호소하였으며 벨마비로 진단되었다. 페그인터페론과 리바비린 병합요법을 지속하면서 관찰하였다. 환자의 벨마비는 페그인터페론 치료를 중단하지 않았음에도 3개월후 증상이 회복되고 이후 벨마비 재발 없이 현재 경과관찰 중이다. 만성 C형 간염에서 페그인터페론과 리바비린 병합 요법시 벨마비의 발생 가능성을 염두에 두어야 하겠다. A Case of Bell's Palsy Associated with Combination Therapy of Pegylated Interferon Alfa-2a (PEG-IFN) and Ribavirin for Chronic Hepatitis C Virus Infection Pegylated interferon alfa(PEG-IFN α) and ribavirin therapy is the first line treatment for chronic hepatitis C. Mild complications of the therapy are common, but more serious complications are rare. We report here a case of Bell's palsy that occurred in a patient with chronic hepatitis C virus infection during combination therapy of PEG-IFN α-2a and ribavirin. The patient was 49-year-old man with chronic hepatitis C (genotype 1b) for 8 years. He had compensated liver cirrhosis with splenomegaly. Therapy with PEG-IFN α- 2a 135mcg/week and ribavirin 1200mg/day was initiated. After 9 months of the therapy, the patient showed a loss of muscular tone on the right side of his face. A diagnosis of Bell's palsy was made. The Bell's palsy resolved over 3 months despite continuation of the combination therapy.

In this paper the experiments of breakdown characteristics SF? liquid (LSF?) in model GIS (Gas Insulated Switchgear) were described. From the experiments results, The ability of LSF? insulation is higher than high-pressurized SF? gas. The breakdown characteristics of LSF? were produced by bubble formed evaporation of LSF? and bubble caused by high electric emission. It is considered in this paper that the results are fundamental data for electric insulation design of superconductor and cryogenic equipments machinery which will be studied and developed in the future.

With the improvement of industrial society, the high quality electrical energy, simplification of operation and maintenance, ensuring reliability and safety are being required. This paper reviews a basic data of the surface discharge characteristics for teflon resin in not only pure N₂, N2₂:O₂ mixture gas and Dry-Air as being focused on environmentally friendly insulating Gas also SF?. Used electrodes are Needle-Plane. We can find it, surface discharge voltages. Breakdown voltage and dielectric strength are found out and sorted. These results are getting higher as increasing the gas pressure according to the medium effect. By researching the increasing rates of breakdown voltage as following the solid dielectric thickness, it reveals that the thickness also affects the breakdown voltage. Finally, through comparing and corresponding between SF? and Dry-Air & N₂, the possibility of replacement of SF? by environmentally friendly gas is proved.

현재 산업사회의 발달과 더불어 신뢰성 높은 양질의 전기에너지와 운전 및 보수의 간편화, 계통운용의 신뢰성의 확보가 요구되고 있다. 또한 SF?을 대체할 친환경적인 절연매체의 개발이 절실히 요구되고 있다. 이에 본 연구는 모의 GIS내 친환경적인 절연재료인 질소(N₂)와 건조공기(Dry-Air)의 기본적인 절연특성을 구명함하였다. 또한 본 실험의 조건내에서 절연설계식을 도출하여 각종 전력응용 설비의 절연매체로 사용가능시 기초자료로 사용 가능할 것으로 사려된다.

The paper used to the Neral Netwok for a forecasting conservation system A neural network is a powerful data modeling tool that is able to capture and represent complex input/output relationships. The motivation for the development of neural network technology stemmed from the desire to develop an artificial system that could perform ""intelligent"" tasks similar to those performed by the human brain. The true power and advantage of neural network lies in their ability to represent both linear and non-linear relationships and in their ability to learn these relationships directly from the data being modeled. Form results of this study, the Neral Netwok is will play an important role for insulation diagnosis system of real site GIS and power equipment using SF6 gas.

현재 전력설비에 사용되고 있는 SF? 가스는 절연 및 소호성능이 우수하고 회복특성이 뛰어나기 때문에 각종 전력기기의 절연매체로서 널리 사용되고 있다. 하지만 산업사회의 발달로 인하여 도시의 공간 활용의 효율성 측면에서 전력기기들의 소형화, 지중화 및 고 신뢰화가 시도되고 있으며, 또한 온실가스에 대한 규제로서 "도쿄 의정서"가 정식 발효됨에 따라 환경문제로 인하여 전력설비의 SF? 가스의 유출 최소화, 대체 절연물질 개발 등의 친환경 재료의 개발이 새롭게 대두되고 있다. 따라서, 본 연구에서는 SF?를 액화시켜 기존의 SF? 가스와 액체 SF?(LSF?)의 절연파괴특성을 측정 / 분석하여 SF?의 대체물질로 LSF?의 가능성을 검토하고, 혹한 지역에서 운용되고 있는 SF? 이용 전력설비의 온도저하에 따른 문제점을 구명하였다.
