The purpose of this study was to investigate how the future users of a children's garden felt about the designing and operation of the children's garden, which is to be constructed within Korea National Arboretum. For this study, a total of 1,855 elementary school children were selected and then classified by sex and grade. The survey had been carried out to examine the following five items: necessity and advantages of the garden, plants suitable for it, artificial facilities required for it, its space structure, programs necessary for educational activities, and operation programs. The results are as follows: 1. Necessity and advantages of the children's garden: Some 87.7% of respondents said the garden is needed, it would serve for environmental preservation, it would function as a resting place, and it would have educational effect; 2. Plants suitable for it: Uncommon plants which have flowers of several colors; 3. Artificial facilities required for it: Places for experience and rest; 4. Programs necessary for educational activities: maze experiencing and gardening; and 5. Operation programs: Some 86.3% of the respondents said they are needed. They thought educational programs providing the activities of experiencing would be preferable. This study provides basic materials for the planning and designing of the children's garden. When constructing the garden, we should have enough prior discussion for the matters listed above. Furthermore, it is needed to develop several educational programs for efficient operation and management.

Recently the countries breeding bears such as China and Vietnam are promoting a policy that gives relief to wild animals through agreement with AAF and WSPA. Currently our country has lacking breeding space for the increased number of bred bears due to the prohibition of bear import and export from joining the CITES in 1992. There needs to be a place that treats, protects accepts breed bears in the terms of animal welfare. The bear park was hoped to be designed as a means to give relief to bears and promote harmony with the local society, and is made of parking area, waiting area, visitors center, treatment research management facilities, restaurants, food warehouse, food store, bear museum, sanitation facilities, gondola, plaza, rehabilitation area for wild animals, outdoor exhibition center, direct indirect experience area of wild animals, resting facilities and areas, photo zones, bear playground, bear experiencing facilities, fences, information facilities, tree protection facilities and more. The design can be used as a reference in examining alternative measures following the future change in breeding policy as a bear park example which reflected the ecology of a bear in the term of animal welfare.

The foraging behavior of the beauty goby, Pterogobius zacalles, was studied at Mutu Bay, Aomori province, Japan. P. zacalles harvested invertebrates prey from benthic substrates by using two distinct foraging modes: picking substrate among boulders and sucking surface of boulder. Among others, picking substrate among boulders was primarily used foraging mode. The foraging modes of P. zacalles were followed by three stages: searching for prey, feeding and chewing. For foraging, it takes less time to suck out the surface of boulder than pick up substrate among boulders, because the resting site of P. zacalles is close to the place where they do sucking. The diets of P. zacalles primarily consisted of benthic amphipods regardless of their foraging modes. Only the difference was that they can get bigger amphipods when they did picking rather than sucking. Even though it needs more time and energy to do picking, P. zacalles was compensated by getting a high-calorie diet eventually, therefore prey size can be the determinant of their foraging modes.

In this study, 1 dependent variable and 9 independent variables were established to examine suitable illuminance by spaces in urban parks in consideration of night users' psychological reactions and activity types. Such fixed variables were evaluated by a series of experiments of changing illuminance, and correlation among those variables was verified by correlation analysis and multiple regression analysis to suggest suitable illuminance by spaces. The results of this study are as follows: 1) The independent variables influencing suitable illuminance by spaces in urban parks were directly influenced rather by the psychological reaction of night users than the activity types by spatial functions. 2) Securing suitable illuminance by spaces commonly increased spatial availability, created certain atmosphere, and provided safety in the psychological reaction of night users. 3) Suitable illuminance by spaces in urban parks is: Central square is 31.88lx, resting space 6.30lx, exercising space 33.14lx, children's playground 14.19lx, pedestrian road 12.29lx, entry space 16.30lx, and green space 7.03lx. That is, when a place had more positive activities, spatial illuminance was increased. 4) Though comparison by spaces with the illuminance standard for urban parks as mentioned in KS A 3011-1993 can not be made, such illuminance was relatively compatible with the permissible range of illuminance in the author's opinion. It is expected that this study investigating suitable illuminance by spaces for night use in urban parks, will provide necessary knowledge for securing suitable illuminance by spaces in urban parks through classifyingin detail the illuminance standard of KS A 3011-1993. Besides, by helping make us aware of the importance of illuminance in urban parks as well as of external space in the night, this study will contribute to academic research and development in the field of landscape architecture and associated fields and be utilized in establishing legal and institutional standards.

This study carried out to analysis the characteristics of periodic changes of landscape facilities with the apartment sites in Cheongju City. The construction periods were divided into the introduction stage (the 1980s), the development stage (the 1990s), and the maturity stage (after 1999). As for the apartment sites constructed in the introduction stage (the 1980s), their landscape facilities were restricted to play and resting facilities. Some of them even were constructed without rest facilities. Since the focus was on the affluent supply of houses in the 1980s, they put a greater emphasis on quantity than quality. Entering the development stage in the 1990s, they started to pave the sidewalks and driveways separately within the apartment sites and build parking lots underground. After 1999, they entered the maturity stage, where the outside spaces of apartment sites began to reflect environment-friendly designs and the initiatives to improve residential environments. The major causes behind the introduction of high-grade materials in landscape facilities in the open spaces of apartment sites are the upgraded level of living standards and the diversified patterns of activities taking place in the open spaces. The environmental formative works were placed alongside waterscape spaces to create a beautiful and harmonious landscape.

This study was designed to determine the trans fatty acid (tF A) contents of 41 take-out food items in Daejeon and Chungcheong Province. Total fatty acid composition and tFA contents of samples were determined by gas chromatography (GC) after fat extraction (Folch method). Maximum fat content among the observed samples was obtained from theater popcorn (13.74${/cdot}$38.09%) while minimum content was observed from the glutinous rice doughnut. 31${/cdot}$5.44%). The contents of tFA (g/100 g food) in toasts, glutinous rice doughnut and ggwabaegi (twisted doughnut sold in streets) ranged from 0.02 to 0.56 g while those in fried sweet potatostick (from highway resting place), fried squid and theater popcorn ranged from 0.05 to 3.08 g/100 g. As a result, most samples showed the tFA content as less than 1 g (g/100 g food) except one sample from theater popcorn which contained 3.08 g (g/100 g food) as tFA content.

The purpose of this study is to determine the personalizing characteristics of detached housing that reflect the housing needs according to the residents' participation in the back-to-countryside community village. For this study, 15 households of Jagun-maul at Namwon in Jeonbuk provided responses to the semi-structured questionnaire on housing consciousness, housing needs, and views on lifestyle. In addition, 15 plans were analyzed about the shape of the plan, the composition of LDK, the type of access, and the type of special space. The results were as follows. 1) The number of households under the elementary education stage was larger than the number of households above the middle education stage. Most of the households revealed the housing consciousness of 'house as resting place'. Households under the elementary education stage showed a housing consciousness for family-oriented life and households above the middle education stage showed a housing consciousness to interact with neighbors. 2) Households under the elementary education stage preferred LK style while households above the middle education stage preferred LDK style. Most of the floor plans had a front entrance and sliding door for the access from living room to garden. 3) Special spaces such as a loft, 'Ondolbang' (room with underfloor heating), study, maru, 'Toenmaru' (narrow wooden porch), family room, workroom, and toilet with outside door were arranged on each floor plan.

The internal streets of mixed-use commercial complexes, which are the extension of urban streets, are being changed from a mediating space aiming at movement to a staying-type space according to the change of mixed-use commercial complexes. And they function as a resting place of user with court and plaza, and act as an urban public space, and accommodate an activity arising from the gathering of many people. As a result, a role of new relaxation and community space is played in the center of the city. And the aspect of publicness is brought into relief. Hence, this study is intended to examine the characteristics that the internal streets of mixed-use commercial complexes have, and furthermore, it is intended to show the planning characteristics in the contemporary mixed-use commercial complexes. With regard to the method of research, first, space configuration and role of internal streets was examined according to the change of mixed-use commercial complexes on the basic of precedent research and literature review. And the internal streets of mixed-use commercial complexes were classified into doorway part, traffic line, and open space. And the characteristics of internal streets in the mixed-use commercial complexes through the concept of architectural 'publicness' were derived as accessibility, amenity, perceptibility, openness, connectivity and symbolism. The internal streets of mixed-use commercial complexes should be changed by the space planning to secure continuity with the city on the basis of accessibility and connectivity and to reinforce visual openness in the internal streets in order to improve amenity and perceptibility, accordingly the mixed-use commercial complexes will be also born again as symbolic public space in the city. Variously changing elements to improve publicness very importantly act on the planning of internal streets in the mixed-use commercial complexes, and therefore researches should be continuously carried out.

A Corynebacterium sp. capable of utilizing diaminododecane (DAD) were isolated from the soil by enrichment culture. Among 9 different kinds of substituted alkanes containing CN, $NH_2$, Cl, and SH groups (monoterminally or diterminally substituted) tested as carbon source, the isolate, designated as DAD 2-3, utilized DAD, putrescine dihydrochloride, dodecane and laurylamine. Dodecanethiol, thioanisole, decanedithiol, dicyanooctane, laurylcyanide,and dichlorodecane were not utilized. When emulgen 950 was added to the medium, the growth of DAD 2-3 was slightly accelerated. Isolate DAD 2-3 grown in the medium with DAD as carbon source formed .alpha.-ketoglutaric acid. Metabolic product of DAD 2-3 grown in a medium without nitrogen source was different from that of grown in a medium with $NH_4NO_3$. When glucose, putrescine, n-dodecane and other alkane derivatives were tested in place of DAD, isolate DAD 2-3 yielded products different from those they formed with DAD suggesting specificity of DAD as a carbon source.

Soil purification theory is the method using the soil micro-organism like aerobic and anaerobic for treatment of wastewater. The soil has many kinds of micro-organism and it multiply as change of the environment. Unlikely other methods, the soil purification theory is adaptable to inflow water change; moreover, it can process the T-N, T-P without any special method and management. The top is covered with the improved soil which can remove the bad smell and is used for resting place according to planting the lawn. This study is focused on analysis of the treatment processing of wastewater comparing inflow with outflow water. As a results, removal rate of the processing the BOD, COD and SS is almost 90~100% and it is 60~80% in T-N, T-P.
