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.

The author obtained three kinds of humic acid from the soil of suburbs in the Wonju city, sediments of Wonju stream and Maeji reservoir in 29 April 1986. The yield of each humic acid was 7.23 g, 3.35 g and 4.61 g per sample 200 g. In the physicochemical characters, the COD varied from 65.9 ppm to 54.9 ppm and BOD showed 6.7～15.9 ppm, but the standard humic acid was COD 58.9 ppm and BOD 6.5 ppm in 0.01 % solution. Doses of the humic acids for 20% methemoglobin formation are as follows; 0.303 mg/m$\ell$ in St. A humic acid, 0.602 mg/m$\ell$ in St. B humic acid, 0.84 mg/m$\ell$ in St. C humic acid and 0.105 mg/m$\ell$ in standard humic acid.

the purpose of this study was to suggest managemental strategies for one-day use recreational area in public sector under competitive environment with private sector. Data was collected from citizens of Seoul, and 10 recreational areas were determined by a preliminary survey. Theses areas were regarded as "products", then positioning was applied to these products. Perceptual map was produced by multidimensional scaling to identify degree of competition among areas. Properties, which were developed by the Kelly Repertory Grid, were utilized to understand the strong and weak points of each area. Ideal types of recreational areas were analyzed by PREFMAP, then the size and distribution of recreation market of Seoul were found by grouping of individual ideal point by cluster analysis. Several strategies were suggested to enhance the competitive power for public recreation areas, and a few comments were described to improve this method for future research.

The landscape structure of the both pre-industrial and industrial cities should be influenced to the topographical feature , religious thoughts, political ruling system and history. In the major socio-cultural factors in the pre-industrial townscapes in korea, the Feng - Shui(poongsu) which is an acient human settlement organization system based on the “Yin - Yang” principle and “Five Elements” and “Chryaegogong”system were the most important factors to the formation of traditional town scape in Korea. The landscape during the Japanese colonial periods were basically reorganized through change of “Boundary”, “Center” “Direction(path)” and “Domain” which were expressed by distinct traditional townscape in Yi dynasty. The physical shapes, meanings and behaviors of townscape were expressed properly of the intention of the colonization. As changes to the mordern industrial cities, the townscape had been amended landscape elements of the Japanese imperialism to an ideology of rebirth nation. Also as changes to the modern industrial cities, “Boundary”, “Center”, and “Domain” spreaded into the suburbs by funtionalsm and these were expressed an incoherent value system which were the advancement of growth, pursuit policies as well as an advancement of science techniques.

This study is to analyze dwelling environmental planning in old age of middle age. For this purpose. the data were collected by using questionnaire distributed to 332. The data were analyzed by Chisquare test. The major findings of this research were as follow: 1. In housing plan of old age. they prefer new house .that is not exisiting house. independent house and ordindry housing region in the suburbs of urban. 2. It is 69.3～99 square meter what size of house is suitable for independent life of aged person for living with children. it is 102.3～132 square meter. 3. In the stage of independent or semi-independent life. they want aged couple-independent life. In the stage of dependent life. they want to be cared with children. 4. The garden(madang) is the most important space for age couple in establishing housing plan. They want to amplity life recuperation center and job providing facilities. In old age housing project. they prefer housing type with facility that combine old age house with young age house. According to increasement of dependence. the service support system required flexi-care-system.

238 strains of bacteria were isolated from sewage and soil samples collected mainly in Seoul and its suburbs by enrichment culture on crude oil or hydrocarbon minimal medium. Of the isolates, 68 strains were tentatively identified as the genus Pseudomonas, 11 strains as Alcaligenus, and 10 strains as Acinetobacter. Of the 68 strains of Pseudomonas sp., 35 strains were identified as P. aeruginosa, 5 strains as P. fluorescence, 10 strains as P. putida, and 2 strains as P. mendocina.

The objective of in this study makes investigation into the characteristics of concrete as to properties and blended ratio of crushed aggregates through experimental researches. In this study, river sand is blended with crushed sand as to investigate the quality change and characteristics of concrete with variation of blend ratio of crushed sand(50, 60, 70, 80, 90, $100\%$). Measured the air contents and slump to investigate properties of fresh concrete, and unit weight and compressive strength in age of 7, 28days to investigate properties of hardened concrete. The experimental results of crushed aggregates' qualities were all satisfied with Korea Standard's values.

This studies is the typological study to classify the characteristics of Floor plan in wooden house that is built in the suburb of Korea through case studies. For this type classification, I took several criteria as follows: number of floors, location of entrance, approach way to inner room, location of step, arrangement way of public space and private space, those are considered as important elements for the determination of Floor plan. Ive got 10 representative types by analysing and synthesizing the relationship between these elements. I expect that these study results would be good materials for the developing new model of wooden houses that is more proper to our life.

Research into the use of recreation forest accommodations, the main facilities in these forests, and user satisfaction with them has been carried out for recreation forests in the suburbs of Daegusi and Gyongsangbukdo. This study aimed at providing background material to support the increasing demand to improve the facilities of recreation forests and to educate recreation forest staff about how to provide better service. User satisfaction with recreation forests as determined through regression analysis was affected by the following factors in this order: indoor recreation, the indoor space, outdoor recreation, time satisfaction factor, and activity opportunities. The level of satisfaction is affected by the force of factors above. The order of effective offerings of accommodations is presented according to the results.

During the last several years, interest in broad-band power line communications (PLC) has been grown over medium voltage(MV) power distribution lines as well as low voltage lines. This paper introduces a medium voltage PLC test field that is set up in the suburbs of Euiwang city in Korea. This test field could be used not only for the measurement of communication channel environment but also for internet service. This paper shows the configuration of medium voltage test field with network devices like MV signal coupler and the results of channel environment like noise and impulse response. It also shows the service performance of PLC access network through network management system.
