Four species of Paraphysomonas collected from the fast- ice covered area Syowa Station, East Ongul Island ($69^{\circ}00'S,\;39^{\circ}35'$) ,Antarctica occurred in the seawater throughout the year and occasionally in the sea ice. P.. antarctica is distributed to a water depth of 35m at 51.3 during the period from August 1983 to January 1984 and also down to 600m St. 5 in September 1983 at cell concentrations of 300-350 cells/ml. The Paraphysomonas spp. were dominant during the period from July to November 1983 in the area studied. The mode of the occurrence and vertical distribution of Paraphysomonas apparently coresponds to those of the bacteria and orgarnic debris-like matter in the seawater. The main components of the plankton population in the area studied, under ice-covered conditions, are Paraphysomonas, Choanoflagellates and bacteria. This work clarified that Paraphysomonas is one o f the most important bacterivores in the microbial loop of the Antarctic marine ecosystem.

This study is to propose key directions of Busan North Port redevelopment for revitalization of waterfront. Since 1960s, there have been a lot of port redevelopment projects around the world. In Korea, Busan North Port redevelopment project is the first one which aims to make waterfront citizen-friendly within old port area. Many ports will be redeveloped soon after the Busan North Port redevelopment. At this time this is the basic research to lay groundwork for the systematic and efficient port redevelopment. We analyze the good examples of the world through case studies and suggest the problems and important elements of success of port redevelopment. Also we propose the objectives for waterfront revitalization and the visages of waterfront within port area. And then we analyze the situation of Busan North Port and examine the blueprints issued by national and city government. After that we suggest some ideas, such as land use plan, on North Port redevelopment for revitalization of waterfront in Busan Port Area.

According to the New Town Development Plan, Gang-buk area, a symbol of slum in Seoul will be changed new residential area. There are a lot of challenges for success this project. First of all, new ways of city plan "pre-plan and development" and "environmentally friendly development" are necessary to carry out this plan. Another important idea is how to overcome conflicts such as unbalanced development, a traffic jam and environment problem. Also, Government and a citizen agree that this project have to accept eco-protectable and sustainable development theory. For increasing green area ratio and keeping eco-diversity, planting at roofs and water circulation system in residential complex are compulsory. Green network based on environmentally friendly development provides a natural energe stream on eco-system and protects a city from air pollution, hot air island phenomenon and a flood.

In order to investigate food purchase frequency of elementary school children and its related ecological factors, 431 4th, 5th and 6th grade elementary school children and their mothers, living in Seoul and Daejon, small city and rural area of Chungnam Province, were participated in this study. The subjects and their parents were surveyed by a self-recording questionnaire about food purchase frequency and some ecological factors. Average height and weight of the subjects by gender and grade were similar to or a little bit more than the 1998 Korean Growth Standard. According to relative body weight, 30.6% and 10.8% of the subjects belonged to under-weight and obesity categories, respectively. Of the subjects, 46.9% used PC telecommunication or internet, 53.8% of them used it for less than an hour per day, and 46.4% watched TV for 2 to 4 hours a day. About 42% of the subjects spent 500 Won or less daily to buy snacks. A half of the subjects took snacks once a day because of hunger. Mothers' nutrition knowledge score was averagely 8.16 out of 13 full score and the average attitude score was 43.22 out of 50 full score. Foods purchased more than once a week were milk and yoghurt, cookies, ice-cream, ramyun, and gum in order. Family income, parents' education level, mothers' nutrition knowledge and food attitude score, students' snacking frequency and TV watching time showed significant correlations with purchase frequencies of some individual food items. In conclusion, the elementary school children considered taste most important rather than nutrition in buying snacks and most frequently bought carbohydrate foods and concentrated sugars except milk. Ecological factors such as mothers' nutritional knowledge and food attitude, TV watching time and snacking frequency had influenced the children's food purchase frequency. Accordingly, it is necessary to educate both children and their mothers about good food purchase and the importance of snacking.

Our society confronts a new social demand to protect the environmental equity of the people, and the green open space that is a representative public property which takes a very important role for the residents in less privileged urbane area in terms of providing amenity without requiring individual expenses additionally. This study aims to identify the current status and problems based on the environmental experiences of the actual residents, excluding the simple physical status, in relation with supplying public property of green open space, and the study put focus on the old downtown area of Jeonju-si which is a test-bed of urbane regeneration planned by the government. Residents in less privileged area evaluate the importance of green environment of park very highly as a factor to enhance their quality of life, but as they do not have well-established environmental infrastructure to back up their needs practically, they face difficulties to use such environment and show low level of satisfaction. In particular, as such characteristics appear remarkably among the least privileged urbane people in the less privileged urbane area, their dependence and expectation upon the environment of green open space is very apparent and, therefore, it is urgently needed to improve their environment for public green park area for the less privileged urbane people.

Since it is important to understand the bio-climatic change in Seoul for ecological city planning in the future, this paper gives an overview on bio-climate analysis of urban environments at Seoul. We analyzed its characteristics in recent years using the observations of 24 of Automatic Weather Station (AWS) by Korea Meteorological Administration (KMA). In urbanization, Seoul metropolitan area is densely populated and is concentrated with high buildings. This urban activity changes land covering, which modifies the local circulation of radiation, heat and moisture, precipitation and creating a specific climate. Urban climate is evidently manifested in the phenomena of the increase of the air temperature, called urban heat Island and in addition urban sqall line of heavy rain. Since a city has its different land cover and street structure, these form their own climate character such as climate comfort zone. The thermal fold in urban area such as the heat island is produced by the change of land use and the air pollution that provide the bio-climate change of urban eco-system. The urban wind flow is the most important climate element on dispersion of air pollution, thermal effects and heavy shower. Numerical modeling indicates that the bio-climatic transition of wind wake in urban area and the dispersion of the air pollution by the simulations of the wind variation depend on the urban land cover change. The winds are separately simulated on small and micro-scale at Seoul with two kinds of kinetic model, Witrak and MUKLIMO.

Theme trail construction should be changed from existing form which connects line to line, or point to line. It should be developed into area form. The project of Trail construction must be converted in area form. The aggregate of the points which is a base element of walk is a line, and the harmonious connection of various line is the area. The close relationship with points and lines is important to operate the project of trail construction in area form effectively. Subject of the project of Theme trail construction of area form must become the village residents which are being contiguous in trail. They must operate management and about trail. The project of Trail construction of area form the plan making is established and if the subjects which, will operate and manage that place are decided upon according to theme must construct the trail of the wide area concept which connects the trail of that trail and neighborhood. If becomes like that local resident and the citizen will be able to coexist with mediation of Trail. If the project of Trail construction of village resident leading is propelled applying rural amenity resources in a way, the trail model which one phases advances could be presented for ecological, economical and cultural.
