According to the complexity and the pluralism of the modern cities, they are changing themselves into the multinoded and social - classless urban environments. The sudden drift of population to the cities is giving rise to the serious environmental problems, and the rapid increase of recreational needs among the citizen is changing the urban society into a leisure - oriented one. In order to coping with the abrupt change in the social and natural urban environments, the various fields of urban society should be co - ordinated. The study uses the green - city concept to get solves the incongruity of urban structure in Chonju City. The existing open space maps were drawn up by the various techniques such as the analysis of the topographic maps and collected data, the interpretation of the aero-photographs and the reconnaissance of site. The authors suggested the existing condition, and the problems and potentials of open space elements in Chonju City through the analysis of the existing condition maps. After synthesizing the contents of analysis, the 7u(hors established an exclusive open space system for Chonju City.

The purpose of this case study is to provide the basic knowledge and the rationale for establishing the professional personnel position of Landscape Architecture(LA) in local Government of Korea o the basis of the characteristics and adoption system of professional personnel organization in comparison with the cases of Japan, the United States of America, and Germany. I have analyzed the case of Chonju City, Chollabuk-Do, recruited professional personnel of LA by using informal career position, to justify the needs and the division of professional Landscaping works of the city and to figure out drawbacks of the current adoption system of professional personnel in South Korea. In have found the following results that 1) City Mayor in Korean local Governments do not have the proper authorizing rights of recruiting the special personnels for performing urban policy, which is under controls of the Official Appointment Regulations, 2) because of no official position status for specialist in the fields of LA, the Chonju City had been recruited them as Urban Planner status through an informal process, 3) the section of Park and Urban Forestry was established under the control of Department of Culture and multimedia Industry, 4) the fields of specialized works of LA are defined as the work of ecopolis design and planning, biotope networking, ecological bridge and ecological restorations, and 5) the professional positions for LA should be established in Official Appointment Regulation for the urgent needs of local Government sin South Korea.

In order to investigate the origin of sulfate in rain waters and to evaluate the feasibility of using sulfur isotope method as a tracer of atmospheric pollutants, the sulfur isotopic ratio of sulfate in rain waters collected in Chonju city from October 1994 to March 1995 was monitored and was compared with those of possible sources proposed by previous works. The pH of rain waters shows an intermediate acidic range from 4.45 to 6.88 and their daily variation appears to be well correlated with to the amount of precipitation. The sulfur isotopic ratios of sulfate in rain waters show a highly restricted range from 0.0 to + 1.8‰. The ${\delta}^{34}S$ values are similar to those of soil and pine tree surrounding Chonju city, but largely deviate from those of China. D-parameter($d={\delta}D-8{\delta}^{18}O$) of rain waters varies from 9.4 to 28.8. The values indicate that the rain waters in Chonju city are originated from the rainy front of China continent. All data obtained from this study suggested that sulfate in the rain waters collected in Chonju city was mainly derived from the sulfur dioxide gas emitted by the petroleum combustion. Therefore, sulfur isotopic study for the precipitation provided an excellent tool for environmental assessment in this region and for tracing the source of atmospheric pollutants.

In the cellular mobile communications as decreasing the cell radius to increse the reuse factor of frequencies, the handoff requests are increasing so that the efficient handoff decision making becomes a crucial problem. In this simulation study, we evaluate a set of handoff algorithms based on fuzzy-multicriteria decision making. These algorithms uses the parameters including the received signal strength intensity, the bit error rate and the distance between a mobile station and a base station. We compare the fuzzy algorithms in terms of call block ratio and handoff request ratio and call force ratio, and show the applicability of those algorithms in the cellular mobile communication systems.

This thesis is to newly understand the value and the meaning of Chonju Palkyong(全州八景) by the specific gravity in making a counter-proposal in other to improve the landscape identity of modern city and at the same time. I intended to group the grafting device for the preservation and regeneration of modern history cultural environment through the interpretation of landscape construction. The meaning system of Chonju Palkyong showed the symbolic system which a landscape construction, four directions and two places has and exhibited the landscape shape possessing a luxuriant local feature peculiar to Chonju, preserving visual bound language of a classical Palkyong. Especially, it implies the use of the substantial landscape experienced factor, the expressions about natural phenomena and the matter which has melted human living circumstances. The landscape construction and it's form show the system which forms the different time field, a far landscape and a mid distance landscape and a near landscape, etc., under the visual, psychological, scenic influenced area, preserving the feature of the similar and typical type of Sosang Palkyoung（瀟湘八景) which intended to seek the local reappearance of the famous site experienced type and natural matter which famous place and local conduct were combined. The object space of Chonju Palkyong area representing the nature of historical landscape cultural assets, pushed by the greater part of the development based theory, shows injured aspects, but needs to play a part to seek such a up-to-date successive plan as the reconstruction of the destroyed historical landscape area which motivated Palkyong, the establishment of useful area, the embodiment of the cultural identity of Palkyong area and the becoming of the educational cultural life space. The analysis of the landscape construction of Chonju Palkyong and the grouping of the modern successive plan which I considered in this thesis, will be able to become a fundamental data to carry out the preservation of historical landscape and the landscape plan in the city.

This study suggests the methods of the assessment and creation of biotopes in small and medium sized cities, in Korea. For this purpose, Chonju city was selected to classify and asses the biotope types. Moreover, relevant legislations to conserve and enhance urban biotopes were examined. The results of this study are as follows: 1) There were two approaches to asses the potential of urban biotopes in medium-sized cities. One was the urban scale evaluation for urban green spaces and the other was the biotope scale evaluation for the classification and evaluation of biotopes. 2) The urban scale evaluation was developed through overlaping analysis of landuse and vegetation factors. This study also included the conception of watershed. In this conception, three watersheds in Chonju city were characterized. According to these characteristics, individual programs for conservation and enhancement of urban green space were suggested. 3) For the biotope scale evaluation, Selected site was inclusively mapped and field investigation actually was carried. There were total 9 types of bitopes. Especially landuse was appeared in various evaluation items were vegetation structure, area of green space, condition of vegetation and vegetation profile. Mt, Gonji and Dukjin park, Chonbuk national University and fields were evaluated highly I the potential. 4) The biotope programs were based on the results of assessment and physical characteristics of biotopes. The uniform and simple levels on vegetation must be modified with various levels of vegetation structure and vernacular plants. And the physical characteristics like Points, Corridors and Patches can be organized by the conception of biotope networking theory. 5) The proper legislative environment was the clue elements for the biotope programs. Until now, only five types of parks and two types of green space are defined and the minimum size of green space has been proposed by the law. So, it is necessary to enlarge the conception of green space in legislation and improve the quality of green space by amending the related regulations. This study has limitation because it was selected only in Chonju. Through the continuous studies, we need to apply this other small and medium sized cities, South Korea. Also the data collection and management of theme maps such as actual vegetation, landuse and a soil must be done preliminary.
