The purpose of this study is to make some plans to utilize the man power of the aged The necessity of such a study is to solve the economic, physical, and psychological problem caused by the rapid increase of the population of the aged for the elongagion of human life span, and the problem for the loss of the role of the aged, etc., in a degree through their participation in society, and by mitigating the economically destitute problem which is a most seriously confronted problem, to let the aged have the volition and worth of life. Results from such a study are as follows: In the first place, in order to promote the employment of the aged, there need extension of the kinds of work suitable to the aged, preferential employment of the aged, malting the enterprise`s employment of the aged which has been stipulated as an encouraging matter in the law related to the promotion of employment into a compulsory provision, etc. As a policy to extend employment of the aged, there should be supports from both the government and local government and participation in the program of the employment of the aged by enterprises should be induced, and in the meantime, there should be a political support giving a tax benefit to the enterprises which employ the aged according to a ratio of the degree of the employment of the aged, and also development of the kinds of jobs suitable to the aged is required. Regarding the program of the employment of the aged, in consideration of the activation and efficiency of operation, there should be increase of the operation expense so that function can be activated, and there needs a kind of educational agency where vocational training is practiced for the aged according to the special characteristics of a region. Also, regarding the age-limit retirement system, it is not desirable to be daunted, only considering the present situations of the nation, but it is sound to elongate the age limit of employment, thereby lightening the burden of the aged to support their children and enhancing `the idea of respecting the aged and taking food care of parents`. And giving jobs to the aged, it is sound to make the aged enjoy their lives with volition and worth of life, making them free from their sense of helplessness or aliennation.

Purpose of the grounding system design are establish a safe environment for personnel as well as the general public in the vicinity of the power system equipment, and establish a low resistance connection to earth such that protective devices detect and isolate faults quickly and potential rise of the grounding system does not exceed a value which could damage electrical equipment. This paper deals with the grounding system design for the electric facilities. In this paper, emphasize the necessity of the computer programs for the grounding system designs. Especially, earth soil models for the grounding system design are must used two-layered soil model.

This paper presents a standard grounding scheme for bridge and tunnel areas where earthing wires cannot be easily buried. Specially, a new grounding method in which structure grounding devices are used shows good grounding effects like the earthing-wire grounding scheme. The proposed method can be a measure for equal potential in case earthing cables are disconnected.

목적: 말기 간질환으로 간이식 수술을 시행받은 환자 중 원인 질환이 C형 간염인 경우는 한국에서는 아직 증례수가 적지만, 최근 빈도가 높아지고 있다. 본 연구에서는 C형 간염으로 간이식을 받은 환자들의 간이식후 이상 경과와 재발 및 치료에 대하여 알아보고자 후향적 연구를 시행하였다. 대상과 방법: 1992년 8월부터 2002년 8월까지 간이식 프로그램에서 시행된 587예의 간이식 중 C형 간염의 원인 질환이었던 16예(2.7%)를 연구 대상으로 하여 C형 간염 재발을 중심으로 본 임상 경과와 그에 다른 처지에 대하여 환자들의 의무기록과 임상자료를 분석하는 후향적 연구를 시행하였다. 결과: C형 간염으로 간이식을 받은 16예 중 성별로는 남자 11명과 여자 5명이었고, 정중 연령은 56±6세(42-62)이었고 정중 추적 기간은 6±13개월(1-41)이었다. 13예는 생체부분 간이식을 시행받았고, 3예는 뇌사자 전간이식을 받았다. 간이식후 이상적 재발이 의심되었던 경우는 16예 중 9예(56.3%)를 차지하였고, 평균 재발기간은 5.2개월이었다. 조직학적 재발은 8예(50%)이었다. HCV RNA PCR 검사상 양성 소견은 90.9%로 검사가 시행된 시기의 환자들을 대상으로 했을 때 임상적 재발 및 조직학적 재발군 모두에서 양성이었다. 조직학적 재발이 관찰된 8예 중 5예에서 리바비린 단독투여를, 2예는 인터페론 및 리바비린 병합투여를 시행하였다. 치료 후 경과상 혈청 aminotransferase치가 정상화되거나 거의 정상범위로 호전된 경우는 6예(75%)이었다. 결론: 본 연구를 통해 C형 간염으로 간이식 수술을 시행받은 환자들에서 C형 간염의 재발률은 높았으며, 이는 외국의 경우와 유사한 결과를 보여주었다. 그래서 C형 간염의 재발 및 재발이후 간경변으로의 진행을 막는 것은 환자 및 이식 장기의 생존을 위하여 중요하며, C형 간염의 재발에 대한 적절한 protocol의 개발이 필요하다. Background/Aims: End-stage liver disease caused by viral hepatitis C has been increasing recently in Korea. In this study, we investigated the clinical progress, recurrence, and management of hepatitis C patients who underwent liver transplantation. Methods: We retrospectively reviewed the clinical progress and management of 16 patients (2.7%) with hepatitis C among 587 liver transplant patients from August 1992 to August 2002. Results: Eleven cases among 16 patients were males. The median age was 56±6 (42-62) years and the median follow-up period was 6±13 (1-41) months. Thirteen cases underwent living donor liver transplantation and three had cadaveric whole liver transplantation. Clinical recurrence occurred in nine cases (56.3%) and mean time of recurrence was 5.2 months. Histological recurrence cases were eight (50%). A positive result of HCV RNA PCR was found in 90.9%, and all cases of clinical and histological recurrence in groups in the same periods were PCR-positive. among eight cases showing histological recurrence, five patients were managed by ribavirin monotherapy, two patients received interferon and ribavirin combination therapy, and one patient was not treated at all. The serum aminotransferase level was normalized in six cases (75%) of them. Conclusions: We observed that the HCV reinfection rate of a transplanted liver was high in this study, as in other reports in the literature. The prevention of HCV recurrence and the management of post-recurrent cirrhotic change are crucial for graft and patient survival. We think customized protocols are needed for every situation of recurrent hepatitis C.(Korean J Hepatol 2003;9:180-187)

Purpose: Graft interposition arteriovenous fistula (GAVF) graft has been used for the chronic renal failure patients when autogenous arteriovenous fistular procedure is not feasible. Reported, mean first year primary patency rate of GAVF was 40-60%, and the secondary patency being 50-70%. The purpose of this study is to evaluate the patency rate of our AVF using synthetic graft, and factors influencing on the patency rate. Method: To evaluate the patency rate of GAVF and the causes of GAVF occlusion, we analyzed 430 cases of GAVF from January 1998 to December 2000. 430 graft interposition was performed on 357 patients, accounting 36.9% of the total 1163 AVF procedure. Result: The primary patency rate were 69.8% at the first and 66.6% at the second year. The mean occlusion free interval was 15.8 months. The secondary patency rate was 82.0% at the first year, and 71.2% at the second year. The mean secondary patency interval was 18.5 months. Early occlusion within 1month of surgery has been due to a misjudgement in evaluation of adequate artery and vein (11/16, 68.8%). Majority of the occlusion occurred after 5 months of surgery (37.8%). In late occlusion cases, the common causes were somewhat different. They were intimal hyperplasia at venous anastomosis site and improper hemostasis or sudden changes of hemodynamics during dialysis. Conclusion: These data lead us to conclude that a skilled judgement of a surgeon is still the most important factor for successful AVF graft surgery in early outcome. Intimal hyperplasia at venous anastomosis site remains to be the main cause of long term failure.
