  • In order to investigate the deposition chara.cteristics of water-soluble ionic components in dustfall in Kwangju city, dustfall samples were collected by deposit jar for one year from December 1992 to November 1993. The depositjon amount of dustfall and water-soluble ionic components ($SO_4^{2-}, NO_3^-, Cl^-, NH_4^+, Na^+, Ca^{2+}, Mg^{2+}, K^+$) were measured. The total deposition amount of dustfall was 10.0 ton/$km^2$/month and showed seasonal trend of Summer and Spring > Fall and Winter. The total deposition amounts of water-soluble components showed 2.41 ton/$km^2$/month and seasonal trend of Summer > Fall > Spring > Winter. Deposition amount of $SO_4^{2-}$ was 0.99 ton/$km^2$/month which makes up 41% of water-soluble components. The deposition amounts of dustfall and watersoluble components according to the sampling points were approximately similar to each other. From this result, it can be estimated that the deposition amounts of dustfall and water-soluble components in dustfall were more influenced by the seasonal variation than the regional emission characteristics of pollution source. The content of each ionic component to the deposition amount of water-soluble components showed in order of $SO_4^{2-} > Cl^- > NH_4^+ > Na^+ > Ca^{2+} = K^+ > NO_3^- > Mg^{2+}$ respectively.

  • The pharmacokinetics of atenolol (25 mg/kg, i.v.) in the folate-induced renal failure rabbits was studied. Renal failure was induced by the i.v. injection of folate (50, 100, and 200 mg/kg). At folate dose of 100 and 200 mg/kg, the serum creatinine concentration (Scr) and blood urea nitrogen (BUN) increased significantly compared with control rabbits. Plasma concentrations and AUC of atenolol increased significantly at folate dose of 100 and 200 mg/kg. The elimination rate constant $(K_{el})$ and total body clearance $(CL_t)$ of atenolol decreased significantly, and half-life ($t_{1/2}$) and mean residence time (MRT) of atenolol increased significantly at folate dose of 100 and 200 mg/kg. The serum creatinine concentration $(S_{cr})$ correlated well (p<0.05) with half-life $(t_{1/2})$ and elimination rate constant $(K_{el})$ of atenolol, as well as BUN with AUC and total body clearance $(CL_t)$ of atenolol.

  • The distribution of spiders on paddy Holds in the suburbs of Kwangju city and the seasonal fluetuation of their population were surveyed for two years from November 1975 to November 1977. The results obtained are summarized as fallows: 1. The total number of species of the spiders on paddy fields collected in Kwangju area was 38 which belong to 24 genera and 13 families. Out of these 16 species were already known to exist in this area, and two other species were those known to occur in Korea. The remaining 22 species were new collections among which Cornicularia vulgaris 01 was the one with no record of collection in Korea. 2. The spiders on paddy fields collected in this area were mostly those belonging to two families i.e. Erigonidae and Lycosidae, and predominating species were Gnathenarium dantatum(WJDER) and Oedothorax insecticeps BOES. et STR. 3. The population density was highest in November just before wintering and lowest in March and April after wintering and an intermediate peak in July and August.

  • This study was performed to investigate the awareness of an ecological city and its related variables and the willingness to move to an ecological city and its related variables. Data were collected through a questionnaire survey given to 491 residents in Mokpo, Kwangju and Muan in Chollanam Province. Awareness of the ecotogical city was medium level, half of the respondents were not aware of the ecological city. Multiple regression analysis was conducted to estimate the effects of the variables on the awareness of the ecological city. The most significant variable was environmental knowledge. Next, experience in environmental education and homeownership effected on the awareness of the ecological city. Those who knew about environmental pollution and environmental disruption had a self-reported higher degree of awareness of the ecological city. Those who had experience in environmental education as well as those who lived in their own house were more aware of the ecological city. Other variables were not statistically significant. Half of the respondents were willing to move to the ecological city. Seven variables were related with willingness to move to the ecological city. Those who knew about the environmental pollution and environmental disruption preferred to move to the ecological city. Those who lived in multi-housing had more of a willingness to move to the ecological city. People with a higher education as well as the younger group preferred to move to the ecological city. Those who were more aware of the ecological city and had more ecological-oriented values had more willingness to move to the ecological city. Salaried men and professionals were more willing to move to the ecological city than non-employed people. Among those variables environmental knowledge was the only influential variables on willingness to move to the city.

  • The only record of spider's from Cholla Namdo was made by T. Kambe in 1953. They were collected from Mokpo area which is located south-west coast of Cholla Namdo and included 24 species belonging to 8 families. In this paper are given for the first time a iist of spiders from Kwangju City, inland of Cholla Namdo. wis located at the center of Cholla Namdo. More than 5,000 individual spiders were collected by one of the junior author, J.K. Yoon during autumn in 1570. In spite ef rather large number of spiders were collected, collecting season and the locality are restricted, number of species was reiatit·ely small and many young spiders were undeterminable, A total of 50 species belong to 15 families, including 5 unrecorded species from Korea, were identified. Unrecorded species were as follows: Uloborus yesoensis $(S_{AITO},\;1934)$ Pirate piraticus $(C_{LERCK},\;, 1757)$ Stemmops sp. Trochosa ruricola$(D_E\; G_{EER},\; 1778)$ Erigone koshiensis $O_r$, 1960

  • This study aims to find out the genetic characteristics of gridded subdivision area which has its origin from ancient local administrative city-Sangju, Jeonju, Namwon, Kwangju, Chungju. The spatial structure, based on the inter-relationship among gridded subdivision area, city wall, and topographic condition, and the morphological characteristics of gridded subdivision area are analyzed. The points of analysis on morphological characteristics of gridded subdivision area consist of the size of unit block, the organization system of unit block, the orientation of subdivision line. As a result of the analysis, three main characteristics are found. Firstly there can be found no same land subdivision rule among study areas. Secondly, the morphological features of study area were the products of cumulative process of different subdivision areas which were developed in different periods. Thirdly, the original regular gridded land subdivision seems to have been carried out in the object of a farm-land cultivation around 7th century. And there was a change of land-use from farm land to urban land-use during the later 7th century and 8th century.
