Recently, the number of unsold apartments has been increasing, and apartment furnishing companies have tried a marketing strategy by utilizing the outdoor space for differentiation. There are many differentiation strategies. One of them is to improve the dwellings-on-ground space in apartment complex. Owing to the high density and high-rise of apartment buildings, the dwellings-on-ground apartment complex have been recognized as not good housing by residents in korea. The precedent study on the responses from residents showed the negative effects mainly due to sunlight, daylight, view and privacy and the positive effects from good accessibility and good environment for children and elderly people. The purpose of this study was to improve the dwellings-on-ground space and to suggest the most appropriate type of the dwellings-on-ground space through the residents' desires and preferences. In this point of view, this study shows three results for the design improvement: 1) Providing private gardens and individual accesses to the dwellings-on-ground. 2) Providing private garden with flower bed to intensify the visual aspect. 3) Furnishing variable transformation of unit plan in dwellings-on-ground, for example, maisonette, etc.

Indigenous strains of Trichoderma species isolated from rhizosphere soils of Tea gardens of Assam, north eastern state of India were assessed for in vitro antagonism against two important tea fungal pathogens namely Pestalotia theae and Fusarium solani. A potent antagonist against both tea pathogenic fungi, designated as SDRLIN1, was selected and identified as Trichoderma viride. The strain also showed substantial antifungal activity against five standard phytopathogenic fungi. Culture filtrate collected from stationary growth phase of the antagonist demonstrated a significantly higher degree of inhibitory activity against all the test fungi, demonstrating the presence of an optimal blend of extracellular antifungal metabolites. Moreover, quantitative enzyme assay of exponential and stationary culture filtrates revealed that the activity of cellulase, ${\beta}$-1,3-glucanase, pectinase, and amylase was highest in the exponential phase, whereas the activity of proteases and chitinase was noted highest in the stationary phase. Morphological changes such as hyphal swelling and distortion were also observed in the fungal pathogen grown on potato dextrose agar containing stationary phase culture filtrate. Moreover, the antifungal activity of the filtrate was significantly reduced but not entirely after heat or proteinase K treatment, demonstrating substantial role of certain unknown thermostable antifungal compound(s) in the inhibitory activity.

The purpose of this study is to gain an in-depth understand of the dwelling needs of residents who are interested in Cohousing. To do this, we interviewed 18 urban residents who wanted a community life; investigated consciousness of neighbor relationships; and analyzed their consciousness of Cohousing residences, preference types, and spatial needs. At first the research has revealed that the neighbor relationships of the participants were not very close and that there was a difference in awareness levels between a 'good neighbor' and 'strange neighbor' with regard to neighbors, though all of the participants required a vitalization of these relationships. Second, Cohousing residence types could be divided into the 'life preferred type' and 'space preferred type', depending on the differences of pursued dwelling interests. These could be further segmented into the 'leisure life preferred type' and 'daily life preferred type', 'public space preferred type' and 'individual space preferred type'. Thirdly, preferences for Cohousing types varied depending on differences in priority with regard to important concepts of the social-physical environment (e.g., community property, effectiveness, naturalness, economic feasibility, and individuality). Finally, we found that the greatest needs were for public gardens and exercise space as aspects of the common spaces. Agreements pertaining to special use were considered as most important during the design process of the common spaces.

The idea I set my thesis upon was to develop a methodology for the visually impaired to perceive an environment through their other senses. Since the Blind perceive spatial relationships by combined association of their other senses, it was essential to create a setting where their senses can be amplified. Thus this garden was designed to accommodate two or more of blind person's senses at once to provide more of '3-D' spatial relationship. The main goals of this thesis are, first, to create a place where the Blind can enjoy and nurture their own specific interests. Second, to reveal the nature in its allowing individual analysis and interpretation of a garden. Third, to move away from the prejudice of gardens for the Blind being made of only touching and smelling. To achieve these goals, the most important task was to establish a sense of space. In order to do so, five principles were used; Perspective, Enclosure, Light/Shade, Form, and Environment. After all, the garden for the Blind does not proclaim its purpose in loud terms nor in obvious manner. It should attempt to provide joy, serenity, and activity; a freedom to choose, recognize and analyze nuances of garden, the rhythm of enclosure and openness to experience variety, also to delight in subtle changes and to just imagine.

The rear garden of the Ch'angdok Palace is considered to be representative of gardens of the 15th century to the end of Choson Dynasty in the early 20th century and is very well preserved. Therefore with its long history, it's been represented in various way. This study tried to interprete the rear garden of the Ch'angdok Palace in terms of 'text through king Jungjo's "Sangrimshipkyog". Jungjo's "Sangrimshipkyng" that describes scenery related to ten place of the rear garden of the Ch'angdok Palace was written when he was a crown prince. And the scenery of ten places can't be separated from their physical looks and those ten places were quite different from now. For that reason, to begin with, this study recomposed those ten places through maps and drawings that revived the current looks and rear garden. And what poems tried to tell and what meanings whey had in the literacy of that age that allowed "poem enchained ten scapes" were studied in the context of co-relationship with space. As a text it is very ancient and questions arise on how to correctly interpret the information it holds. But this interpretation is only one side of the various aspects that the rear garden of the Ch'angdok Palace has compared to its long history. In light of the present age an interpretation can have richer and more varied meanings, creating many new viewpoints. creating many new viewpoints.

The purpose of this study is to develop the creative play environments for children. Physical environment is very important for play of child. Play activities of chad depends on materials and resources of physical environment around housing. To achieve the purpose of the study, following research questions are performed: 1) to investigating the play environments and its maintainence in Daejon 2) examining and analyzing the contents, safety, and functions of the playgrounds selected based on above findings 3) suggesting the creating play environments for child. Eighteen playground were selected and evaluated objectively by trainned personnel; the subjects(55children and 39adults) who used the playgrounds evaluated the playground subjectively. The results were as fellows: 1) Playgrounds selected in this study were conventional playgrounds, in which child can only do simple physical activities. The playground has installed fixed equipment in a row, in an effort to utilize whatever space available. However, such places are neither developmentally or economically sound. 2) The playgrounds evaluated in this study were very poor in matter of content, safety, and functions. The playgrounds lacks play materials, equipment, national features, storage, and do not follow national safety guidelines and standards. 3) The playground should offer much wider variety of natural material- textures including grass, dirt, stone, brick, plastic, metal, bark, leaves, sand, water, and a larger variety of plants, gardens, natural areas, and animals.

The law prohibits use of human excreta without proper treatment since 1968 in Korea, but the rate of infection of parasitic diseases is high among all ages of people. An examination of parasitic eggs in soil and vegetables was performed from April to September, 1974, soil samples were collected near toilet, at gardens, at vegetable farms with excreta used and not used, and strawberry farms in Shindong myon, Chunseong-gun, Kangwon province, and vegetables collected were cabbage, young radish, lettuce, Welshonion, spinach and strawberry. Main findings are as follows 1. Positive samples of Ascaris lumbricoides are 18 out of 25(64%) in the soils near toilet, 9 out of 28(3.2%) in the garden soils and 8 out of 18(44%) in the soils of vegetable farms. 2. Trichocephalus trichiurus and Enterobius vermicularis were detected in 8 soil samples respectively Trichostrongylus orientalis 7(25%) and Ancylostoma duodenale 3(11%) out of in the soils near toilets. 3. Parasitic egg negatives are 62(55%) out of 112 soil samples. 4. Ascaris lumbricoides is found in 11 roots(48%) of cabbage and young radish out of 23 respectively, 14 lettuce(34%) out of 41,4 Welsh onion(40%) out of 10,3 spinach(33%) out of 9, and 2 strawberry(11%) out of 18. 5.

In this study we established reliable methods for conservation of seeds of Phaius tankervilleae as an orchid genetic resource. The seeds, which were dehydrated to 5% water content and preserved at $4^{\circ}C$, showed no decrease in viability and germinability after three months. After storage for six months, however, the seeds showed a drastic decrease in germinability, even though survival rate was high. For long-term preservation of seeds of P. tankervilleae, cryopreservation is applied to the freshly harvested seeds. When the seeds were cryopreserved by the vitrification method for up to 12 months there was no apparent deterioration effect of storage time. These results indicate that cryopreservation by the vitrification method is useful for long-term conservation of P. tankervilleae seeds, which are difficult to preserve for more than three months under dry and low-temperature conditions.

As part of a study to understand the current status of Korean plant species propagated in foreign countries, we conducted extensive surveys on Korean living collections in the Arnold Arboretum of Harvard University, the oldest public arboretum in North America. Specifically, we collected and identified the voucher specimens of the living collections and further examined the collection databases to understand the history of how Korean plants were introduced to the Arboretum. We found that a total of 154 Korean taxa (belonging to 49 families and 81 genera) have been planted in the arboretum. Most plants originated from seeds that were directly collected in Korea or obtained via seed exchanges with botanical gardens in Asia, Europe, and U.S.A. Of the 154 taxa, 16 are Korean endemic species, and three are listed as endangered species. In addition, 62 taxa are as floristic regional indicator species of Korea used by the Ministry of Environment.
