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.

Over the range(OTR) has been applied for cooking and ventilation functions especially in northern Amarica. Because flow rate and operating rpm of the double sided sirocco fan for ventilation are much higher and than the microwave oven system, the major noise source is the sirocco fm. Recently, the quiet fan development is one of very important issues for amenity. In this study, the noise source identification using multi-microphone array system was carefully carried out and numerical simulations for understanding the aerodynamic and aeroacoustic of the fan were peformed. The sound level of tonal noise is predicted with a good accuracy but that of the broadband shows some discrepancy. In order to reduce the broadband noise, the inlet region of sirocco fan have to be modified that the secondary flow should be suppressed. Based on these results, new low noise fan and OTR is now developing.

본 연구의 목적은 소음진동규제법을 비롯한 각종 소음진동관련 규정의 목적이나 정책의 목표에 기술된 '정온'의 의미를 명확히 하는 것이다. 이를 위해 먼저 사운드스케이프 사상에서 나타난 소음의 개념과 쾌적성을 고찰하고, 관련 연구자의 '정온'에 대한 정의를 검토하였다. 그 결과 '정온'은 조용함으로서 양호한 음환경 조성의 기본 요건이지만, 그것만이 절대적 의미의 정온이 아니며 high acoustic quality의 관점에서 사람들이 선호하는 소리가 포함되고 원하지 않은 소리를 마스킹할 수 있는 유쾌한 환경까지를 포함한 상대적 의미가 되어야 함을 알 수 있었다.

Urban streams have been severely degraded with wastewater and concrete structure over a prolonged period. The Chonggyecheon Restoration Project recovered a stream in the downtown Seoul with landscaping, plantings and bridges after the cover concrete and elevated asphalt road were removed. The project has been criticized partly because it is not an ecological restoration but rather the development of an urban park with an unnaturally straight flowing stream, artificial building structures, and artificial water pumping from the Han River. Nevertheless, the public have praised the project and almost 100,000 visitors per day come to see the reeds, catfish, and ducks. The stream restoration project is attractive to central and regional government decision makers because it increases the public concern of landscape amenity. Several projects such as Sanjichon and Kaeumjungchon are on going and proposed. These projects have a common and different respect in scope and procedure. The Chonggyecheon project in the process of environmental impact assessment (EIA) and prior environmental review system (PERS) reviewed the environmental impacts before development. Kaeumjungchon in the PERS and Sanjichon without EIA and PERS are reviewed. EIA and PERS systems contribute to checking the ecological sustainability of the restoration projects. A stream restoration project is a very complex task, so an integrated approach from plan to project is needed for ecologically sound restoration. Ecological stream restoration requires 1) an assessment of the entire stream ecosystem 2) establishing an ecologically sound management system of the stream reflecting not only benefits for people but also flora and fauna; 3) developing the site-specific design criteria and construction techniques including habitat restoration, flood plains conservation, and fluvial management; 4) considering the stream watershed in land use plan, EIA, PERS, and strategic environmental assessment (SEA). Additionally the process needs to develop the methodologies to enhance stakeholder's participation during planning, construction, and monitoring.

The rapid industrialization since the 1960s has caused considerable changes in the appearance of Korean cities. The huge demand and cityward tendency derived from the increase of population with such the expansion from 9 millions in 1960 to 43 millions in 2003, have resulted in number of problems such as the falling-off in the quality of life, amenity, and safety. And above all, the urban identities is not to be found obviously in the cities. With regard to these problems, the re-creation of cities should be emphasized to make environmental, economical, and social improvements and to restore human-oriented activities. In the course of making new improvements cities need to preserve the characteristics and maintain the concordance with their environments. In other words, the restoration of cities ought to be made in the aspect of continuity, which means the accession of genetic factors inherent in cities. In this background, concerning about the system on apartment house especially relating to environmentally sound restoration and comparing with that of Japan, this study proposes the direction needed in the development of urban space.

Rural areas dominates the country landscapes in size with less population and rich traditional heritages as well as natural landscapes. Rural community groves (RCG) and Dangsan groves have been established by community residents during a few hundred years, and most of them have been disturbed. Only a few RCGs and Dangsan groves remain for an extensive period with efforts from community residents. These remnant RCGs and Dangsan groves are highly evaluated representing Korean rural cultural landscapes. Sound understanding on the structure of the rural landscapes and their role on the rural community environment is required to provide an appropriate policy for managing rural landscapes. This study aims to understand the characteristics of RCGs and Dangsan groves in the cultural landscapes, to investigate policies and issues of the advanced countries on RCGs and Dangsan groves, and to overview domestic policies for rural landscapes. The study results showed that there is a close relationship between RCGs and main issues discussed in EU countries. Ministry of Agriculture & Forestry of Korea, Ministry of Environment and Rural Development Administration have to focus on the potential of RCGs and Dangsan groves for multi-functions of agricultural and rural areas, natural streams, rural amenity, direct subsidy for landscape preservation and rural tourism. Based on the findings, this study suggests that RCGs and Dangsan groves will provide benefits to develop rural-mountain-sea villages and to enhance country's landscapes as well as local landscapes.

This study focused on the analysis of satisfaction and preference of residents' for water space as a environmental friendly facility in residential complex. The purpose of this study is to serve design data of water space in residential complex, in order to make water space that residents' satisfaction are high. In this study, residents' satisfaction and preferences of water space in 5 residential complex were analyze through a questionnaire survey of residents. The major findings of the study are as follows. First, in terns of the need of the water space, 60.4% of the respondents answered that water space are need to improve the amenity. Secondly, in terms of satisfaction, 57.3% of the respondents have been satisfied with location of water space in the residential complex, and the maintenance satisfaction degree is above average level. Overall satisfaction degree is above average level too, but it is are not high as compared construction cost. Thirdly, in terms of preference, 26.5% of respondents have been prefer to the combined type of water space, and 25.9% of respondents prefer to dropping water type, and 25.9% of respondents prefer to flowing stream type. It appeared that the preference levels of 3 type is high similarly, so we can assume that residents prefer to moving water type because of having a feeling refreshed through the sound of water. The results of this study can be used as the design data of water space in residentialcomplex and expected to contributed in making the water space that residents' satisfaction are high.
