벡터의 평행성을 보장하는 FINSLER 접속의 변환에 관한 연구
金秉斗 慶一大學校 1999 論文集 Vol.16 No.2
We shall investigate how a Finsler space change by some transformation which is characterized as a transformation of a Finsler connection preserving vector parallel in direction. In the paper (〔3〕), M. Hashiguchi and Y. Ichijyo dealt with it and had some results. In the section 2, we study a locally Minkowski space under the transformation. In the last section, we investigate R-symmetric, Z-symmetric, P-symmetric spaces. Main results are as follows: 1) A locally Mikowski space remains to a locally Minkowski one by the transformation (1.3) with respect to gradient sκ(χ). 2) If a R-symmetric space remains to be a R-symmetric one by the transformation (1.3) with respect to gradient sκ(χ), then the space is zero curvature. 3) If a P-symmetric space remains to be a P-symmetric one by the transformation (1.3) with respect to sκ(χ), then the space is a Landsberg space.

1. It is not right for us to think that we can keep our certain physical, power as ever during our whole life if we get it once. 2. In fact, we should have continuous physical training and sports during our life because our bodys muscles are apt to become weaker and werker without having our continued active physical exercises. 3. we can keep a certain active physical power in social life only by our continued physical exercises and sports with steady endurance and interests while students. 4. Therefore the purpose of this paper is to encourage and guide students' extracurricula sports activties so that they are able to accustomed to having sports in their daily life.
白鼠의 카드뮴中毒時 마늘, Dimercaptosuccinic acid 및 N-acetyl-DL-penicillamine 投與가 카드뮴排泄에 미치는 影響에 關한 硏究

It has been revealed from several studies that garlic is highly effective on protection of cadmium or mercury poisoning as much as well-known chelating agents of 2,3-dimercaptosuccinic acid(DMSA) and N-acetyl-DL-penicillamine (APEN). This study was conducted to find out the effect of garlic on excretion of cadmium as an effort to reveal the mechanism of the protective effect and compare it with the effects of DMSA and APEN. The cadmium was administered via intraperitoneal route for 3 days. The experimental agents of Garlic, DMSA and APEN were dosed via oral route and the agents had been administered from the day before the injection of cadmium for 12 days in the first step and then they had been administered for 7 days from two days after completing 3 days injection of cadmium. Feces and urine of experimental rats were collected separately at every 24 hours using metabolic cages, and the cadmium concentration in the material was measured by the atomic absoption spectrophotometry. The results of the study were as follows; 1. When the experimental agents were administered from the day before the injection of cadmium, the excretion of cadmium via feces was excellent for 10 days but that via urine was poor in the garlic treated group comparing with that of DMSA or APEN treated group. It suggests that the garlic enhance the excretion of cadmium via feces more than urine. 2. When the experimental agents administered from 2 days after the 3 days injection of cadmium, the excretion of cadmium via feces and urine was not so good as expected in the garlic, DMSA or APEN treated group comparing with the result of the group treated with cadmium alone. Though the differences of cadmium excretion amount were not remarkable, the excretion amount was high in the APEN treated group, the DMSA treated group and the garlic treated group in order. The excretion amount was much higher in feces than urine. It suggests that the garlic hardly facilitate the cadmium excretion if the garlic was administered after the poisoning happened.
