To investigate the prognostic factors for the survival of transplanted kidney in patients with end-stage renal failure, 59 cases of renal transplantation from September 1986 to Feburary 1997 in Chungnam National University Hospital were analyzed retrospectively. The results were as follows: 1)The mean age of recipients was 33.8 years and that of doners was 38.9 years. The male to female ratio of recipients was 2.5:1, and that of donors was 1.03:1 2) Living related donore(LRD) were 79.6% and living non-related donors were 20.3%. The HLA-identical donors(ID) in LRD were 18.7% and HLA-haploidentical donors(HID) were 61.0%. In living non-related donors(LNRD), mean matched HLA-AB antigens were 1.56 and mean matched HLA-DR antigens were 0.56. 3) The average 5-year patient survival fate was 94%, and average 5-year graft survival rate was 70%. The 5-year graft survival fate of HLA-ID was 100%, and those HLA-HID and LNR were 70% and 36% respectively. 4) Total 33 episodes of acute rejection were found in 45.8% of transplanted patients. The number of acute rejection episode did not show significant difference between LRD and LNRD(P > 0.05). There was no significant difference in MLC between two groups(p > 0.05). 5) In comparison between the 18 patients who lost their graft function in 5 years and 17 patients who are maintaining graft function for more than 5 years, MLC was significantly lower in patients with functioning graft than of patients with non-functioning graft (p < 0.05). The number of rejection episode was also lower in patients with functioning graft than that of the patients with non-functioning graft(p < 0.05). However, there were no significant difference in recepient and donor age and history of pre-transplantation donor specific transfusion between two groups. With the results above, we can speculate that adequate donor selection according to good matched HLA typing and low MLC is very important for graft survival in renal transplantation. Prevention and treatment of acute rejection in renal transplantation is also na important factor for graft survival.

This experiment was carried out develop dilutor for the usage of liquid semen of Korean native ogolgye semen, The results obtained are summarized as follows; 1. The hightest live sperm index was obtained from the semen diluted with diluent containing 0.8mg/ml(65.8) of nature pollen and 0.4mg/mi(65.7) of processed pollen. 2. Semen extended with dilutor containing 0.8mg nature pollen and 0.4mg processed pollen per ml of dilutor showed higher live sperm index among five semen diluents during storage.

In increased scale enterprise web environment, the role based access control is effective technology which reduce to complexity and cost of access control. For the role based access control is safely realized on the web, the user property that included role, group, permission and authentication information must be ensured authentication, integrity and security. To satisfy this requirement, we designed and implemented secureRBAC Architecture that consider control flow to transmit user property securely.

In this paper the subroutine library of digital computer techniques to the solution of electronic networks problem are discussed. The application of digital-computer techniques to the solution of the integrations relating the terminal variables for linear time invariant inductos and capaciters are analyzed, then on the techniques of numerical integrations trapezoidal method is used. The subroutine library for differential equations and determinations which are used in electronic networks analysis have been developed. Since these programs are the general form, anybody can utilize the programs for his own purpose.
한국인 고혈압군에서 Dopamine D3 receptor 유전자에 존재하는 Bal I 제한절편길이 다형성에 관한 연구

고혈압은 다양한 유전적 요인과 환경적 요인들이 상호작용하여 발병하는 질환으로, 기존의 연구에서 dopamine D3 receptor(DRD3)와 고혈압과의 관련성에 관한 보고들이 있었다. 이에,본 연구에서는 DRD3유전자에 존재하는 Bal I 제한절편길이 다형성이 한국인 집단에서 고혈압과 어떠한 관련성이 있는 지를조사하였다. 환자-대조군 연구를 수행한 결과 이 유전자에 존재하는 다형성은 한국인 집단에서 고혈압과유의한 관련성을 나타내지 않았다. 그러나, 이 다형성을 구성하는 대립 유전자의 빈도를 여러 민족집단의결과들과 비교했을 때. 흑인 집단과 유의한 차이를 나타내었다. 따라서, 이러한 결과는 DRD3 유전자에 존재하는 다형성이 고혈압과의 관련성을 나타내는 지를 정확하게 이해하기 위해서는 혹인 집단을 비롯한다른 민족집단들을 대상으로 하여 광범위한 연구를 수행할 필요가 있을 것으로 생각된다.
