The main purpose of this research is to discuss the urban heat island which will be caused by urbanization, especially by the construction of new town on a wide green zone. Over the last ten years, five new towns have been developed around the Seoul metropolitan area. However these new towns become bedroom communities and create traffic problems between Seoul and its surrounding areas because of an increase in population and a lack of roads and other infrastructures. The construction of another such new town is under consideration in the Pan-gyo area. But it is important that Pan-gyo remains a wide green zone. Many studies show that green space can play an important role in improving urban eco-meteorological, ameliorative capability and air hygiene. The objective of this study is to analyze the urban heat islands of Bund-Dang Si which was constructed in 1996 and of the Pan-Gyo area planned as new town. To investigate the local thermal environment and its negative effects caused by change of the land use type and urbanization we used LANDSAT TM images for extraction of urban surface temperature according to change of land use over 15 years. These data were analyzed together with digital land use and topographic data. As a study result, we found that the thermal island of this area from 1985 to 1999 rapidly increased with a difference of mean temperature of more than 12'E. Before construction of Bun-Dang Si the temperature of this area was the same as the forest, but during the new town construction in 1991, an urban heat island developed. The temperature of forest with a size of over 50% of the investigation area was lowest, which leads us to conclude that the forest cools the urban and its surroundings. The mean temperature of the residential and commercial area is more than +4.5$^{\circ}C$ higher then forest, so this method of land use is the main factor increasing the urban heat island. Urban heat islands and green space play an important role in urban wind systems, i.e. Thermal Induced Air Exchange and Structural Wind Circulation, because of their special properties with regard to energy balance between constructed urban and land. The skill to allocate land use types in urban areas is a very important planning device to reduce air pollution and induce the fresh cold air from green space. An urban climatic experiment featuring a numerical wind simulation study to show the air corridor will be published in a following research paper.

The purpose of this study is to derive indicators and development directions to be considered when planning new towns in the Seoul metropolitan area as new towns are planned to be built. To this end, the following implications were derived after analyzing the survey data of experts in each field using Frequency Analysis and Analysis of Variance(ANOVA) technique. First, the assessment results of the existing first and second phase new towns showed that there were many negative assessments of citizen participation and information sharing, smart technologies and services, social and cultural diversity and inclusion. Regarding the third phase new town, experts said that the most important indicators are accessibility and convenience of transportation, environmental comfort, quality and service of residence. In addition, experts cited the superiority of landscape/design, jobs/self-sufficiency and social/cultural diversity as important indicators. Second, after examining whether the perceptions and assessments of experts differ depending on individual characteristics such as gender, age, occupation, and professional field, the first and second phase new towns showed significant differences only in "gender", and the third phase new town had significant differences in "gender" and "professional field". Third, experts thought that changes in population structure, industry and jobs, quality of life and diversity, environment and climate change, and social and residential welfare should be considered important in the planning of third phase new town. In addition, experts considered expanding park and self-sufficient land as important in the land use plan, and ranked eco-city as a desirable type of the city, and public transportation facilities, park areas and education facilities as the most important living infrastructure.

Hydrogen will be a future eco-friendly energy source that can replace current fossil fuels However when hydrogen gas leaks and people inhale a lot of hydrogen gases, they can have fatal effects fell into comas. Therefore, we need to develop a safety technology and related guidelines for reducing risks of hydrogen leakage. In this regard, we carried out demonstration tests assuming a situation of hydrogen leakage. Before the experiments, we analyze the standards for governor facilities to check vent positions and sensor positions. Then, we select four types of ventilation structures and proceeds with the experiments of hydrogen leakage at 1 LPM and 1.5 LPM. Based on the experimental results, we propose the direction on optimization of vent positions and sensor positions in the hydrogen leakage situation.

Among the towns of GyeongJu and SamCheok on which I have surveyed about their amenity resources in 2010, I chose 5 towns that are close to the Eastsea to analyze the data and to devise how to revitalize fishing villages. And the results are as follows. 1. Although Yangbuk-myeon is geographically located to have all the aspects of fishing village, farming village, and mountain village, the resources utilized are mainly that of mountain village. There is need to utilize actively historical amenity resources like Munmudaewangreung of Yangbuk-myeon. 2. The use of amenity resources of Yangnam-myeon is centered on farm and mountain village. But if they utilize amenity resources of fishing villages of Eupcheon-port's neighborhood, it would be a big help for the revitalization of Yangnam-myeon which is depressed. 3. The fishing mackerels on boat of Gampo-eup Jeonchonri is a successful example of utilization of fishing village's amenity resources. However, there is need to utilize amenity resources of farming and mountain villages that are near to Gampo-eup, so it can attract visitors to stay longer. Particularly, the fishing villages of the East coast must develop 4 seasons program connecting the amenity resources of neighboring farm and mountain. 4. Geundeok-myeon is a town where they made the amenity resources of fishing village into tourist attractions. But considering the wide gap between Geundeok-myeon and neighboring fishing, farming and mountain villages that cannot get the advantage of development, there has to be some inducement in policy so every town can be developed evenly. 5. After analyzing how the towns utilize the amenity resources to make them tourist attraction, it is shown that Geundeok-myeon of SamCheok is the best town which is using fishing village's amenity resources well, and Yangnam-myeon and Yangbuk-myeon of GyeongJu are scarcely using them. About types of tourist attraction, the programs with scenic view of fishing village, with water-sport, and with Eco-experience are needed to improved.

As the population of consumers of outdoor wear expands, there is increasing interest among consumers in trendy lifestyle outdoor. Accordingly, it is essential to develop designs that are drawn from outdoor wear. This can be limited to traditional mountaineering suits, and designs developed from men's outdoor zip-up T-shirts, which are highly utilized in everyday life, are very important. This study developed the design of a summer zip-up T-shirt for men with both functional and aesthetic qualities. Visual images of foreign brands and domestic outdoor-focused T-shirts from the spring/summer seasons of 2013-2019 were collected to analyze the following modeling elements: silhouettes, details, colors, materials, and prints. In addition, the design concept was derived by analyzing presentations from the global outdoor trade Fairs (2013-2019). To develop a sustainable eco-friendly outdoor summer T-shirt for men, the concept was derived according to three categories: eco-friendly, sportism-expressed active elements of sports, and an outro-concept of urban town wear as an outdoor lifestyle. Thus, a total of 12 styles of design were developed. High utilization of the outdoor wear T-shirts (which are also popular as lifestyle wear), is an important aspect of building a segmented lineup of the slow-growing outdoor wear market and supports expansion of the scope of theoretical research on outdoor wear design.

This report designs a landscape plan of six reservoirs in Sihung city which has possibilities both in development and in destruction. The report suggests how to create a leisure space in harmony with the surroundings in Sihung city. Building a leisure town will create the local residents' demand in recreational activities and improve the amenities. Therefore this study analyzes eco-friendliness of the land, conditions of fauna and flora, the quality of water and the usage figures of the six reservoirs so as to develop those six reservoirs more eco-friendly. Based on environmentalism, the leisure spot development plan attribute the ultimate importance to local residents' pleasant leisure time and recreations. With this master plan, the report suggests expanding the city's green space, since the city has under 50% out of the optimal percentage of green space per person. In addition, the report intends to plan each six reservoirs developed separately but organically connected at the same time that those six can put together and become a Sihung Green Way which makes the city's leisure space a belt. Apportioning the six reservoirs development levels in order to balance the development, accumulating and arranging buildings and facilities in available spaces according to the governing law, and creating resting area, promenade and parking lot to make an eco-city. Also the report suggests conserving environment and regulating contamination such as ban on fishing to move forward sustainable development. Since the adventives predominate the site, introducing indigenous plants should be necessary soon.

A lead free piezoelectric material, bismuth sodium barium titanate $(Bi_{0.5}Na_{0.5})_{0.94}Ba_{0.06}TiO_3$ (BNBT), was considered as an environment-friendly alternatives for the current PZT system. A perovskite BNBT was synthesized by conventional bulk ceramic processing technique. In order to improve piezoelectric properties, $La_2O_3$ as a dopant was incorporated into the BNBT system up to 0.025 moi, ana the effects on subsequent the piezoelectric ana dielectric properties were systematically investigated. With increasing $La_2O_3$ contents, the equilibrium grain shape was remarkably evidenced and sintered density was increased. Piezoelectric and dielectric properties were s]town to have maximum values at the $La_2O_3$ contents of 0.02 mol. $La^{3+}$ ions seemed to act as a softener in the BNBT system and to enhance dielectric and piezoelectric properties in this study.

Environmental matters are one of key issues of today's world. At this point, advanced countries are proposing and planning various kinds of policies for sustainable communities. Space designers in those countries are more concerned with regeneration or slow development than development and innovation. As the new government of Korea was started in 2008, it announced 'design Korea project' as key agenda for national competitiveness. But it seems that they are focusing on development of new town than the concept of preservation or regeneration on which most advanced countries put their bases. In these regards, this research starts with the idea that environmental factor in space design is very important and it is directly connected with human survival. With this idea, the researching team created experimental space titled 'regeneration' as one of eco-friendly education program. The team aimed at building up or 'designing one man space-one to one ratio' in deserted place with recycled stuffs. With the idea of 'regeneration' in space, the researcher aims at awakening the sense of environment and putting it into practice in daily living.

This landscape design proposal was presented for a competition for mixed-use development project by project financing in Asan Baebang which was held by the Korea National Housing Corporation in July of 2005. The site is a center of Asan Baebang New Town Development District and has a commercial area of $57,929m^{2}$. Design guidelines and judging criteria of this competition were to build a symbolic center and cultural core for district, to elevate positive image and identity of Asan New Town by attractive place making, to link with separated block in the site and regional context, and to make environmentally sustainable design by creating an attractive waterfront of Jang Jae stream passing through the site. This is the most important condition for the design. Therefore, the authors developed design concept and strategy within the guidelines and this conditions. The schema of the design was introduced by the water in the site. To evolve design concept, we reinterpreted water and context in the site combining with landscape design strategy. So the proposal set the main design concept as 'all that is solid melt into water' as if Marshall Berman said. By doing that, design concept of the proposal evolved as follows: 'extension' of water and greer, 'a joint' of space,'newness' of experience, 'breath' of consensus with each other. The spatial concept of this project was developed by expressing five theme spaces; eco zone, entertainment zone, art zone, culture zone, leisure zone. These theme spaces were consecutively placed along the pedestrian path and to consists of vertical layer in each level and diverse design technique and spatial effects are used.
