양인태,천기선,이상윤 강원대학교 산업기술연구소 2005 産業技術硏究 Vol.25 No.B

The goal of this study is to generate a landslide potential map using GIS(Geographic Information System) based method. A simple and efficient algorithm is proposed to generate a landslide potentialities map from DEM(Digital Elevation Model) and existing maps. The categories of controlling factors for landslides, aspect of slope, soil, vegetation are defined. The weight value for landslide potentialities is calculated from AHP(Analytic Hierarchy Process) method. Slope and Slope-direction is extracted from DEM, and soil information is extracted from digital soil map. Also, vegetation information is extracted from digital vegetation map. Finally, as overlaying, landslide potentialities map is made out, and it is compared with landslide place.

Because c very little information available regarding the poisonous plants distributed in Cheju-lsland, the author made a survey of such plants from March. 1974 to Dec., 1977. The results obtained were as follows: 1. If not all, 68 families, 137 genera and 190 species of poisonous plants distributed in Cheju-island were classified. And 190 species were divided into 137 spp. of herbs, 45 spp. of shrubs, 3 spp. of molds and 5 spp. of toadstools. 2. Relatively, a large number of poisonous plants were distributed in wild field. Jungle area, inhabited region, seashore and high mountainous area took next place gradually by the number of plants. 3. And according to their toxic chemical components or poisoning types, they were clas-sified as 16 spp. of cyanogenetic plants, 14 spp. of oxalate-producing plants, 14 spp. of nitrate-producing plants, 10 spp. of photosensitization and 136 spp. of the other activities.

Population concentration phenomenon of city needs large-scale nde, and It is important elements that develop the circumference but, it is difficult to evaluate effects that ride gets land utilization change. Therefore, this research evaluates change and effect of land utilization as political to subway station that is main ride of Seoul City, and chose standard and position for night place arrangement of electric railway station. Research contents analyzed subway station effect area interior and external land utilization change taking advantage of GIs's buffer function and RS's classification technique, and decide precedence at subway station establishment and chose position of subway station for effect area outside area.

In university of Korea, the computerization of facility management is lower level than other management areas such as educational matters. administration, library. computing center, teaching assistance, and teaching methodology So we need urgently the blueprint for an information-oriented and integrated facility management system. In this research, It is presented and implemented an FMS(Facility Management System) for efficient management of the ground and underground facilities on a campus. This studies is computerized the drawings, protocols. and ledgers. It is used a GIS(Geographic Information System) to get the geographical information of facilities The data more efficiently could be search and update on this system . The decision making process understanding the present facility condition, and analyzing the condition of location could be performed easily by the GUI(Graphic User Interface) of the system

고사리 근경의 hot ethanol-water soluble fraction이 가토적혈구막의 Na-K-ATPase 활성도에 미치는 영향

양기천 제주대학교 농과대학 제주도축산문제연구소 1988 畜産論叢 Vol.3 No.1

The influence of the hot ethanol-water soluble fraction of dried bracken rhizome (bracken extracts) on the Na-K activated ATPase activity in the rabbit erythrocyte ghosts was investigated. Also the studies on the relationship between amino acids-activation and the bracken extracts-inhibition on the Na-K- ATPase were performed. The results obtained were as follows : 1. The activity of Na-K-ATPase in the red cell ghosts was inhibited by the bracken extracts. And the degree of inhibition in the 4 × 10^(-4)g% and B × 10^(-4)g% concentration of bracken exracts were significant (p<0.05) 2. The activation of Na-dependent ATPase activity was inhibited by the 4 × 10^(-4)g% of bracken extracts when the sodium concentration was increased gradually and the concentration of potassium was maintained constantly in the working medium. 3. The activation of K-dependent ATPase activity was inhibited by the bracken extracts when the potassium concrntration was increased gradually and the concentration of sodium was maintained con-stantly in the working medium. 4. The activation of Ca-dependent ATPase activity was inhibited by the bracken extracts when the calcium concentration was increased gradually and the sodium and potassium concentration was maintained constantly in the working medium. 5. The activation of Na-K-ATPase was produced when the amino acids containing a typical active group(NH_(2) f lysine, OH of threonine and imidazole of histidine) were added in the working medium. The bracken extracts did not ihibit those amino acids-activation of Na-K-ATPase. 6. The bracken extrats produced remarkable inhibitio on the Na-K-ATPase activity which was stimulated by a typical SH group of cysteine, when they were simultaneously added in the working medium.

Carbon Tetrachloride의 독성에 미치는 Chlorpromazine의 영향

양기천 제주대학교 1969 논문집 Vol.1 No.-

The author investigated the influences of Chlorpromazine(CPZ) on the acute CCl₄ toxicity by measurement of S-GOT, S-GPT activities and LD??. Animals used were healthy mice weighing 20-30g and healthy albino rabbits weighing 1.7-2.2kg. The LD?? was estimated by Behrens- Kaerher method and S-GOT and S-GPT activities by Reitman-Frankel method. The results obtained were summarized as follows. 1. The LD?? of CCl₄in control was 10.7ml/kg b. w. for grouped mice. When, however the grouped mice was pretreated with CPZ (5mg/kg.), it raised the LD?? of CCl₄as 14.0 ml/kg. (Table 1) 2. The activities of GOT, GPT in the rabbit blood serum pretreated with CPZ seemed to be increased slightly in comparison with them of CCl₄alone, but it was not significant. (Table 2,3, Fig. 1,2)

A watershed terrain factor is known to the very important in studies of a stream and a watershed. We have obtained the terrain factor in map directly or we have generated it in a digitalized map. In this study, DTED (Digital Terrian Elevation Data) offering in DMA(Defense Mapping Agency) was used to create a stream and a watershed and to extract the terrain factor. As comparison of the factors gererated in digitalized map the terrain factors extracted in DTED, DTED could be used to extract a terrain factor for a watershed management.

In acetone-ammonia system with amines, N-Substituted hydrazone was synthesized by the oxidation of hydrogenperoxide. The results are as follows : 1. The yield of phenylhydrazone was increased and that of azone decreawed with increasing the aniline added. 2. The excess of aniline was unfarorable for preparation of both azine and hydrazone. 3. Similar behavior was observed for t-butylamine to afford acetone t-butylhydrazone and azine, while cyclohexylamine resulted in the exclusive formation of 2-cyclohexyl-3, 3-dimethyloxaziridine.
