The increasingly severe environmental problems such as resource depletion and ecological damage, and consumers' concern for sustainable fashion, make the fashion industry chain develop towards green energy saving. The purpose of this study is to explore the attitude and consumption psychology of specific groups towards sustainable fashion consumption, as well as their specific views and attitudes towards recycled textiles or fabrics for re-manufacturing clothing. This paper attempts to understand how the characteristics of recycled clothing affect consumer. Based on the review of relevant literature, a series of determinants affecting consumer behavior is determined, and the characteristics of recycled products, such as expression value and social value, are determined. An online questionnaire was designed based on this conceptual framework, and 226 valid, complete answers were received. The results show that the emphasis on social value and environmental protection consciousness can effectively affect consumers' decision-making. These findings were helpful to the research of whole green environmental protection and ecological clothing recycling industry system, promote the sustainable development of the clothing industry.

In Korea, efforts have been made continuously to improve the environment of traditional markets concerning the issues of urban regeneration. In particular, many old cities and traditional markets face a lack of parking spaces. As a solution to this, attempts are being made to prepare underground parking spaces by designing urban planning facilities in three-dimensional ways and utilizing the upper part as a more meaningful space. This study is about the master plan to use the upper green area while creating an underground parking lot at 571 Sinmae-dong, Suseong-gu, Daegu. This green area was defined as a space with dual values, 'defensive green space' that needs to be ecologically protected, and 'active cultural space' where walking flows to the market and various events are concentrated. Three specific design strategies to balance these values were presented. First, to prevent indiscriminate occupation and damage by people and maintain a healthy green environment, securing the maximum amount of undivided green space in the site was suggested. Second, a space layout and a topography and planting patterns that can overcome the morphological characteristics of narrow and long-shaped sites enable the experience of abundant green spaces. Third, providing space to strengthen the connections with nearby urban facilities such as Sinmae Market and Gosan Library can also intensively accommodate cultural activities in various cities. This study has academic significance in providing implications for urban regeneration projects with similar contexts in the future.

우리나라 연안에서 쉽게 발견되는 불가사리는 양식대상 패류의 성패와 치패를 포식함으로써 패류양식장에 큰 피해를 끼치는 대표적인 해적생물이다. 이들은 저질의 상태와 상관없이 어디에나 분포하고 번식력과 재생력이 강하여 그 숫자 또한 많기 때문에 특정 양식장뿐만 아니라 연안생태계 파괴의 주범이라고 할 수 있다. 이와 관련하여 불가사리에 관한 기존 논문을 보면 국내의 경우 강 등(2000)이 양식패류에 대한 불가사리 종류별 포식특성에 관한 연구 등이 있을 뿐으로 불가사리의 산란이나 난발생 및 유생사육시 환경요인에 대한 논문을 찾아 보기 어렵다.

하천은 유속과 수심을 변화시키는 환경과 수역에서 고수부지까지의 다양한 지형변화, 홍수에 의한 파괴와 재생 등 하천 특유의 조건을 가지고 있어 여러 생물이 공존하여 살 수 있는 환경을 가지고 있다. 근래 하천은 친수성을 높이고 하천오염문제를 해결하기 위해 자연친화적인 하천으로 개발 방향이 바뀌고 있지만, 생물 서식처 기능 보다는 친수성이 강조되는 경우가 많다. 본 연구에서는 하천에 도입을 원하는 식생에 대한 환경유량을 분석하여 도입 가능한 하천 영역을 찾는 것이 목적이다. 연구대상지역은 황룡강이며 지형자료는 HEC-RAS의 횡단자료를 이용하여 유한요소망으로 만들어 사용하였다. 하천 식생을 고려한 환경유량을 계산하기 위하여 HEC-EFM을 이용하였다. 연구지역의 수위-유량자료, 도입 가능한 식생의 Life Cycle을 분석하여 HEC-EFM에 입력하여 환경유량을 계산하였다. 산정한 환경유량을 HEC-RAS모형으로 모의하여 환경유량에 맞는 수위 유량을 계산하고 이 결과를 HEC-GeoRAS모형을 이용하여 도입 가능한 영역을 시각화 하였다.

This paper reviews the engineering approach needed to support humans during their long-term missions in space. This approach includes closed plant production systems under microgravity or low pressure, mass recycling, air revitalization, water purification, waste management, elimination of trace contaminants, lighting, and nutrient delivery systems in controlled ecological life support system (CELSS). Requirements of crops f3r space use are high production, edibility, digestibility, many culinary uses, capability of automation, short stems, and high transpiration. Low pressure on Mars is considered to be a major obstacle for the design of greenhouses fer crop production. However interest in Mars inflatable greenhouse applicable to planetary surface has increased. Structure, internal pressure, material, method of lighting, and shielding are principal design parameters for the inflatable greenhouse. The inflatable greenhouse operating at low pressure can reduce the structural mass and atmosphere leakage rate. Plants growing at reduced pressure show an increasing transpiration rates and a high water loss. Vapor pressure increases as moisture is added to the air through transpiration or evaporation from leaks in the hydroponic system. Fluctuations in vapor pressure will significantly influence total pressure in a closed system. Thus hydroponic systems should be as tight as possible to reduce the quantity of water that evaporates from leaks. And the environmental control system to maintain high relative humidity at low pressure should be developed. The essence of technologies associated with CELSS can support human lift even at extremely harsh conditions such as in deserts, polar regions, and under the ocean on Earth as well as in space.

Due to population explosion and develop of the industry, expressways, national roads and railways has been developed a lot. But it increased the disconnection of the ecosystem. The phenomenon of wild animals' habitat simplification has been increased. The damage appeared in succession because of the harmful wild animal. Our country is making efforts relief of some affected farming household's financial compensation. But the affected populations can't sleep at night or they are suffering in their basic life because of this kind of night patrol. This research is based on the study of wild animal's ecosystem and their habits, generate and regenerate supersonic waves and infrasound, prevent wild animal's approach to some extent and stop the approximation effectively, focusing on develop a quadcopter about discrete pulses system.

A set of surveys was performed at Chungchongbuk-Do in 1997 in order to analyze energy related in rice production. Four cases in rice farming were surveyed : traditional farming, no chemical farming, duck farming, mud snail farming. The farmer in traditional fanning has used chemical fertilizers and chemicals such as general farmers. The farmer in no chemical farming has used chemical fertilizers and manure but has not use chemicals. The farmer in duck farming has not used chemical fertilizers and chemicals but brought up duck in paddy. The farmer in mud snail has not used chemical fertilizers and chemicals but brought up mud snail in paddy. The animals n paddy as like duck and mud snail not only eat weeds and insect but also input fertile material by excretion. The results of energy analysis are as follows 1. In view of energy, the duck farming was the most efficient of four cases. The mud snail farming was less efficient than the duck farming, the traditional farming was less efficient than the mud snail farming, the na chemical farming was less efiicierrt than the traditional farming. 2. Relatively to amount of product, non renewable energy was used more in traditional farming than other cases and renewable energy was used more in no chemical farming than other cases. 3. The reason of low energy efficiency in the no chemical farming was to input fertilizers and manure so much. So to input nutrients excessively in order not to use chemicals can make rice farming to be inefficient in a view of energy. 4. The farming to bring up animals in paddy was more sustainable than other cases because input of non renewable energy could be decreased. But in order to make it to be more sustainable, should be developed cultivation method to decrease input of non renewable direct energy such as fossil fuel and electricity .

The government of the UK since the 1990, especially under the new Labour Party, has pursued sustainable development or carbon control as a core strategy for its national development. The seemingly prominent environmental policy for 'greening the government' of the UK as well as considerable achievements in energy and environment indices have attracted much attentions of policy makers and researchers for the 'low carbon green growth' in Korea. This paper tries to see the character of carbon control and environmental policy in the UK not merely as the integrating or mainstreaming policy but a new strategy for national development, that is, for the 'ecologically modernized' state, eco-state, or green state. It defines the environmental policy for carbon control in the UK as the strategy for the green state which has provided it as a principal guide for integrating national policies as a whole, and which has pursued it through market-dependent neoliberal measures. From this point of view, this paper introduces the development process of carbon control and environmental policy mainly under the new Labour Party government in the UK, and gives a reappraisal of both its policy and of energy-environment indices.
