It is said that the goal of the design of good acoustical environment is at first the reduction of undesirable sounds, and in addition the introduction of desirable sounds by which our minds are soothed. The task of creating the desirable sounds leads to the realization of a comfortable acoustic environment and the design of soundscape. It may be an important starting point of soundscape design to select suitable sounds for the target spaces, because each space has a different surrounding condition and requires a special ambient sound. This paper aims to survey preference of the environmental sounds suitable for the public spaces in urban areas such as parks, bus terminals. 35 kinds of natural sounds are rated by 26 pairs of adjectives. The results of psycho-acoustic experiments are as follows. 1. The proper adjectives for expressing the environmental sounds are classified into 6 groups of comfort, pleasure, fullness, variety, distinctness, naturalness. 2. Bird singing, murmuring of a stream, artificial sounds, singing of insects and animals are the affirmative order of preference. 3. Green musics consisted of music and natural sounds are preferred to the pure natural sounds. 4. Sound level relative to background noise causes various preferences to natural sounds in public spaces.

In this study, I investigate how city parks have been created, and what are some characteristics of the location and function of 69 city parks in Tokyo. The city parks in Tokyo have been made in three patterns. The first is planned parks which have been created as a urban facilities considering the scales and types. The second is memorial parks which have been made to memorialize the national monumental event or to preserve natural and cultural resources. The third is public property parks which have been made by occurrence of public vacant land which is resulted from the grant of Royal Garden, restoration of public rented ground, producton of reclaimed land, utilization of dry river bed. The city parks can be classified in five patterns according to distance from CBD and park area. The first is central parks which have historical characteristics strongly. The second is planned parks that are specialized functionally. The third is large scale urban edge parks which are located in the edge of 23-Gu(district) in Tokyo. The fourth is hill parks which have natural characteristics strongly. The fifth is waterside parks that are located along a lake, a pond, a river, or artificial waterside facilities. From this study I have found out that a great effort has been made to activate the utilization of parks for residents in Tokyo, through mnagement goals and ways of parks, composition and chatacteristics of park facility resources, various Events, residents participation in undertaking of parks.

This study mainly aims at suggesting plans applicable to the outdoor of environment-friendly communities in Korea by leveraging more natural conditions and materials when creating an outdoor biotop for an environment-friendly community and generating material types and development techniques enabling a natural circulation system. To this end, materials used in the outdoor of environment-friendly communities and traditional residential areas in Korea and biotop materials found in natural areas were examined. First, when the case examples of environment-friendly communities were reviewed, biotop spaces and materials that may function as habitats were hardly found. Materials used in biotop were mainly man-made structures made of artificial or processed materials, such as concrete, stones, bricks, woods and steels. Meanwhile, the outdoor space of traditional Korean villages had stone walls, soil walls, rock piles and composite piles, which composed of natural materials such as rocks, soil and plants, that naturally formed porous spaces along with the introduction of plants and provided habitats for a variety of insects. In natural areas, naturally created biotop spaces, such as rock piles, log piles, old tree deployment, branch piles, hay stacks and defoliated leaves, were found. Meanwhile, when spaces and materials available for biotop creation were reviewed to create an environment-friendly residential complex, they were divided into fences and hedges, green spaces between parks and residential buildings, ponds and waterscape spaces, zones separating pedestrian walks and roadways, breast walls and slope boundary, plant box and pergola. For each space, materials used for creating biotops and that were found in traditional Korean residential areas and natural areas were applied and suggested.

The purpose of this study is to evaluate naturalness of botanical garden pre- and post-assessed according to the Hemeroby Index in the case study of Daegok Botanical Garden. The results of the study are as follows. 1) The results of the site analysis according to the Hemeroby Index before development have been appeared that highest of poly/meta-hemeroby is 45.8% and the next of meso-hemeroby is 28.3%. 2) After development, the highest of meso-hemeroby is 53.6% and the next of $\alpha$ -euhemeroby is 28.3%. Generally, it is considered that the naturalness according to Hemeroby Indx was lasted higher after development than that before development. 3) Both a-hemeroby and oligo-hemeroby are not appeared before and after development. $\alpha$ -euhemeroby and meta-hemeroby are not appeared before development, but htey increased as much as 16.8% and 6.8% after development. Most of all, the increase of meta-hemeroby after development results from the increase of the artificial facilities (e.g. pavements, buildings and so on). 4) Specially, through the modification of play ground, park lot, pavement classified to meta-hemeroby, it is considered that the Hemeroby Index would be improved. 5) Compared with existing naturalness grade of green space, it has merits to apply Hemeroby Index, especially as a menas of distinguised naturalness assessment in various land use pattern. But there is no clear evidence that limits the minimum size that could be applied with Hemeroby Index. So, we must discuss whether it was useful to apply this standard to such a small specific space as the site of this study.

Modernity which is superficial phenomenon set off the mass scale for mass consumption and provide uniformly artificial environment. But natural destruction, environment pollution, resources exhaustion and so on has been caused by this and now ecology is threatened by destruction and damage beyond the limitation and human beings survival is even threatened. Accordingly furniture development for environment preservation considered environment problem is the urgent real situation. Recent paradigm is the concept of Eco-design which is the green design possible to live together in symbiosis, and new types of alternative furniture are needed in Korea as well. 'Furniture for disassembly' is presented as new method for alternative furniture. Furniture for disassembly can be presented by mainly two directions. The first main characteristic is what is assembled by the use of woodworking joints technique as an assembly structure system without any hardware. The second is what is presented as the structure possible to be assembled by simple manual tools with hardware without any glue. The advantages of furniture for disassembly are environment preservation, space application, transportation efficiency and shapeliness. In manufacture method which is different from present furniture, the application of traditional truss technique which uses various types of custom-made and connection technique in case of assemble structure system without hardware is the typical differences. This assembly method expects not only interest induction about assembly and disassembly of diagram per sub materials but also the development of emotion, the improvement of collaboration, space perception ability and shape sense, the improvement of solid body structure insight and so on, when it use in the furniture for children with the application to many kinds of structure with BANGDOOSANJ (Wedged), JUMUGJANGBU (Dovetail) or NABIEUNJANG (Dovetail Keys) and so on.

본 연구의 목적은 신도시 등의 조성에 있어 지속 가능한 발전을 도모하고 시민들에게 쾌적한 생활환경을 제공하기 위해 도입된 생태면적률을 산정하는 모델을 개발하여 구축의 효율성과 데이터베이스 유지관리의 간편성과 정확성을 확보함에 있다. 특히 생태면적률은 현재 환경영향 평가 뿐만 아니라 친환경 인증기준 중 생태환경기준으로 활용되고 있으나, 생태면적률의 산정도 구축을 위한 지표가 제시되어 있지 않기 때문에 결과자료의 누락, 데이터 수정보완의 어려움과 같은 문제가 있을 수 있다. 따라서 본 연구에서는 GIS를 통해 도형 자료를 구축하고 가중치의 속성정보를 통합하여 관리하는 모델을 제시하였다. 생태면적률 산정은 토지이용계획도를 기초로 하여 건폐지의 경우 옥상 및 벽면 녹화, 비건폐지의 경우 수공간, 인공지반, 틈새투수포장, 자연지반 녹지의 공간유형을 대상으로 한다. 가중치가 부여된 공간유형정보는 도형정보와 통합되고 통합된 자료는 향후 토지이용에 따른 분석을 위해 토지이용계획 정보를 블록 별로 부여한다. 한편, 공간유형별 가중치 적용의 경우 도출방법이 각 지자체나 적용 주체의 상황에 따라 특성에 맞게 판단기준의 조절이 가능하다. 따라서 그 수치가 유동적일 수 있으나 본 모델에서 수치변화에 대한 탄력적인 대응이 가능함으로써 간편하고 효율적인 데이터 구축의 모델로 활용될 수 있다.

The process of designing Cheonggyecheon Entrance Plaza began with researching four keywords: plaza, restoration. modernity and icon. The outcome of the research was reinterpreted into and informed the design. An urban plaza must not only be a stage for civic life but should also be a portrait of the city to which it belongs. Many Korean plazas, however, are treated as if they are parks. Yeouido Park, which was originally a vast urban void, and Seoul Plaza, recently paved with grass, are good example. The strong 'green myth' can hinder socio-political activities. Cheonggyecheon cannot be said to have been 'restored', since it is still disconnected from its origin and upper streams, and the water is circulated by electricity. So it is better understood as an artificial urban waterfront, rather than an ecologically restored stream. This fact might diminish its ecological value, but not its recreational one. The entrance plaza therefore should reflect that the new stream brings back an 'experience', not only water itself. At the same time, the catch phrase of this restoration project was 'post-modern'. The demolished Cheonggye Expressway represents the 'economy drive' of the 1970s, so the newly opened Cheonggyecheon serves as a perfect counterpart to it. But modernity in Korea is the spirit that made many of the good things, not only its shortcomings, we have now. And from the philosophy of this restoration project, we can see that it is still an ongoing attitude in a way. Remnant of Cheonggye Expressway can evoke our nostalgia for the era. There are plenty of symbols in Seoul, both as architecture and objects. But none of them provide citizens with experience, other than the experience of looking at them. Cheonggyecheon Entrance Plaza is a good place to serve as an icon for a dynamic Seoul. From the research, the designer concluded that this plaza should commemorate the incomparable horizontal experience of Cheonggyecheon and the old expressway, amid the vertical metropolis. The Pedestrian Sculpture, which people can stroll on and look out over Cheonggyecheon, is to be made of steel cladding with a core structure and represents the dynamism of the stream, Seoul and contemporary Korea. The choice of material and the steel structure are also ways of creating the icon. The Water Plaza, the space underneath the ramp, will accommodate people and their urban activities, providing an opportunity to play with water. The Waterblades will be a device for the dramatic beginning of the stream, simultaneously camouflaging ugly openings in the outlets. The Wall of Archaeology is to be made with pre-fab resin blocks, translucent enough so that people can see through any archaeological findings of the site. The strong water-resistant character of resin makes the wall steady throughout the flood season as well. Cheonggyecheon restoration project is an effort to combine contemporary urban demand with the once-existing physicality by evoking our nostalgia for it. The project itself shows many socio-political issues of present-day Korea. The entrance plaza design thus is focused on suggesting an icon for the metropolis, simultaneously celebrating the stream itself. Within this space, people will be exposed to a unique experience that any 'green myth' cannot offer.

공원녹지와 물길을 연결하는 조경계획기법이 보편화되었지만, 대규모 계류형 수경시설의 운영과 관리상의 문제가 빈번하게 발생하고 있다. 이에 본 연구는 전주·완주 혁신도시를 대상으로 빗물을 이용한 계류형 수경시설의 지속가능한 관리와 운영을 모색할 수 있는 설치방안을 검토하였다. 이 연구의 목적을 수행하기 위해 수원지와 수로 부분으로 나누어 각각의 시나리오를 설정하였다. 첫째, 수원지에 관한 시나리오는 수로와 수원지에 필요한 유지용수량과 저장공간을 산정하기 위해 물수지를 분석하였다. 분석 결과, 수로 부분 자체는 676.8톤/월의 급수가 필요하지만, 수원지의 생태적 또는 경관적 측면을 고려하여 3,018톤~5,512톤의 저장 공간과 0.75m~1.37m의 수심 유지가 요구되었다. 둘째, 수로에 관한 시나리오는 계류형 수경시설의 유지관리에 효과적인 설비의 계통을 선정하는 것이다. 이를 위해 용수를 고지대로 압송하여 흘려보내는 단일순환계통과 각각의 수공간에 별도 공급하여 독립 운전하는 다중순환계통을 비교 분석하였다. 그 결과, 소규모 동력장치에 의해 독자적으로 운전하는 다중순환계통이 용수공급에 필요한 운전시간을 최소화 할 수 있어 더 효과적인 것으로 나타났다.
