Phytoplankton communities are generally dominated by diatoms in spring and changed to nano- and picoplankton or dinoflagellates groups in summer (Anderson et al., 1994). Many phytoplankton investigators have been used to chlorophyll a as a phytoplankton biomass, as all the phytoplankton contain (Cullen, 1982). The studies of population compositions, primary productivity, chlorophyll a of phytoplankton in the Yellow Sea have been conducted mainly in bays and estuaries with a few studies in the central area of Yellow Sea. This study is to understand the relationship between the environmental factors and cholrophyll a concentration of phytoplnakton in terms of the area and depth in the Yellow Sea and also to identify the characteristics of phytoplankton populations occurring at the most productive periods throughout the yera.

Fast economic growth resulted in fast industrialization and metropolitanization. At that time, housing was supplied in large quantity, and the apartment became a dominant type of housing in Korea It is partly due to the high population density. But, large quantity supply of apartments caused a lot of problems. One of the biggest problems is decomposition of traditional communities. As interest about quality of life grows since the 90's, the recovery of communities is getting an import assignment that should be solved. Architects investigate ways of arrangement and community facilities planning. off-line Communities might be substituted by or supported with cyber communities through the use of IT technology. The construction of cyber apartment is getting popular by the governmental incentive in 1999. At first, the infrastructure has been constructed, and then the current emphasis in on forming the information community to provide various service.

Jeju City has been developed and changed variously by influence of industrialization and urbanization since Jeju City was erected into a city on September 1st of 1955. The purpose of the study is to offer information and data for establishing housing policy and urban planning for being considered the change of housing in Jeju City for the past fifty years. The method of the study is an analysis of documentary records and data and an inquiry of literature. The results are following: 1) The population of Jeju City has increased six times ever before. 2) The ratio of housing supply is 95.3% and the ratio of renting houses has increased than before in terms of the type of occupation of housing. 3) The ratio of collective house is higher than detached dwelling's in term of the type of housing units.

The purpose of this study is to accumulate basic data to establish planning direction of the environment-friendly remodeling through residents' consciousness in apartment Housing. The results are as follows : 1)More than half of residents thought remodeling is influential in decreasing of environmental pollution. 2) The important planning factors of the environment-friendly remodeling appear saving-energy, increasing health & amenity, coping with the change of population & society.

A lot of nursing facility expansions are needed by rapidly growing elder population and operating long-term nursing act for the elderly from July, 2008. To supply facilities in a short period, government is considering a method which is converting usage of existed building to nursing facility. Therefore, we took actual state analysis by interviewing manager, surveying actual measurement and using draft among the converted facilities. To improve and encourage those living environments of nursing facilities, we need to establish design standard of adaptable facility.

Ethanol treatment method was attempted for the selective isolation of ethanol-tolerant fungi from two sites of rice paddy fields around Seoul area. The vertical and seasonal fluctuation of the fungal population were also investigated. The ethanol-tolerant fungi were Talaromyces stipitatus, T. flavus var. flavus, T. helicus var. major, Eupenicillium javanicum, Emericellopsis terricolor, Pseudourotium zonatum, Aspergillus flavus, Cladosporium cladosporioides, Penicillium frequentans, P. janthinellum, and P. verruculosum. The most dominant species isolated by this method was T. stipitatus. It was found that the numbers of fungal species and colony forming units(CFUs) of ethanol-tolerant fungi were higher in Ascomycota than in Deuteromycota. A particular tendency appeared the highest CFUs in autumn, but lower in spring and winter. T. stipitatus was the dominant species of ethanol tolerant microfungi. This result would suggest that membrane lipid composition of ethanol-tolerant fungi isolated from the soils may play on important role in the ethanol tolerance.

Major species of Lake Deganuma has varied depending on the season. Namely, there are Micractinium pusillum, chlorella., Scenedesmus sp. shown up in spring season, Microcystis aeruginosa, Microcystis wesenbergii, Anabena spiroides in summer and autumn season and Cyclostephanos invisitatus, Diatoma in winter season in the Lake. As the number of plankton increased, the zeta potential on their surface of them decreased. For this reason, they were dispersed in the lake though the population increased. Zeta potential of M. aeruginosa showed -20mV when their outer size got smaller. As for coagulant dosing in DAF, large amount of coagulant was effective to get lots of sludge during water treatment.

In the modern city in which the high-density and complex land use is needed, high-rise residential-commercial buildings appeared as a scheme to arrange a metropolitan residence with multiple high-techs and to induce activation of the city with leading the settled population to flow into the city. And the need of the times is to actively apply the eco-friendly notion to the architecture. In this study, the works of Ken Yeang who is regarded as an eco-friendly architect to make high-rise residential-commercial buildings ecological should be focused on with analyses of eco-friendly characteristics in inside, intersection between inside and outside, and outside of his works. The result o the study would be the suggestion to design eco-friendly high-rise buildings which make the city rise in quality.

Our city structure is being complicated from the development of industry and the increase in population. It makes the ground space overcrowded, so underground space is systematized for use. Because this underground space has very complicated configuration, people have difficulty in finding the route in the underground space. Therefore It is demanded to comprehend configuration of the various space structure, predict pattern of the moving and analyze induction factor of the moving. When people are in the conflagration or dangerous situation, they are in the habit of using the route which they are used to go to and from. It is needed to analyze moving pattern of the pedestrian who usually use the underground space for the sake of dealing with conflagration in the underground space. Finally, this study suggested that general characteristic, distribution, moving route of the pedestrian and factors influencing that they choose the route which the research finds out.

This study begins to make inquires about user's opinion of introducing Interior Landscape into Apartment Housing to the problems of contemporary Interior Landscape and suggest the fundamental data to improve it. The city-ward drifting of population drawn from industrial development and aggravation of living condition bring about exclusion of nature and lack of green space. Furthermore, it increases the length of stay of urban liver in indoor space. Thus, dweller's desire to Interior Landscape increase but housing can't follow it. The purpose of this study is to understand characteristics of Interior Landscape, derive essential factors, study plans, establish radical data, and suggest better plans including Interior Landscape through making inquires about user's opinion.
