The rapid industrial and technological development has made the human activities for the utilization of marine resources more complex. Marine spatial management is a space-based approach. It is a comprehensive and integrated management approach. The ultimate goal of marine spatial management is the "sustainable use" of marine resources. The partial approach is applied in the existing marine spatial management, mainly coastal zones which involves integrated approach. Also this showed various limitations including restricted mostly to coastal zones, and limitation to implementation tools. However, for marine spatial management to have a reasonable approach that attaches importance to the relationship between humans and the holistic ecosystem, it is important to internalize a central principle in marine spatial management that focuses on the sustainable use of marine resources. In the present study, four central principles are proposed that will eventually be applied through marine spatial management planning tools. These principles are 1) the establishment of a cooperative decision making and planning system that is based on stakeholder participation; 2) scientific assessment of the current status and impact on the basis of ecology, sociology, and economics; 3) reasonable and optimal spatial assignment based on the forecasting of future-use characteristics and environmental changes; and 4) ascribing importance to the implementation of the results of rational planning processes.

This study aims to identify differences and lessons in eco-school planning techniques and sustainable design methods by analyzing comparatively green building certification system and the cases of sustainable schools in US, Korea and Japan. As a result of the comparative analysis, green building certification system for school facilities, both domestic and international, is categorized into external environment, energy, materials and resources, and indoor environment. From the case study, it is common that roof garden and biotopes are installed for external environment, while energy saving, passive energy utilization methods for natural lighting and ventilation such as arrangement planning, courtyard, top-light, shading devices, solar panel and insulation by roof garden are most frequently used. Also, storm water uses, water saving equipment and sustainable materials are often introduced for resource savings. Concerns for indoor environment is frequently addressed by introducing natural light and ventilation in the buildings, which makes ultimately a comfortable space.

From an sustainable perspective, one unique characteristic of Open Housing is its ability to individualize variable elements (infill) from the permanent elements (support) in accordance with the residents' needs. Such environment-friendly elements of Open Housing can contribute to increasing the life span of the building, reducing the scope of reconstruction, and minimizing the amount of disposed building materials during demolition. The purpose of this research is to analyze the flexibility concept from a typological perspective, so that the concept of open housing can be better understood and its development can be promoted. The main method of this study was content analysis. Based on literature review of flexibility concept in a typological approach, a primary categories were established to describe the flexibility concept such as time for flexibility, scope, and the degree of openness. Subsequently each criterion was elaborated as follows: planning, supply, and utility in the time stage; internal and external flexibility in its scope; and fixed, semi-free, and free flexibility in its openness degree. This research exposes the lack of comprehensive knowledge of Open Housing caused by rather uniform features of previous studies. This research establishes and promotes a systematic approach for a more holistic meaning of Open Housing. This approach should contribute to the proper utilization and further development of sustainable housing.

Although economically viable, the livestock industry is currently facing a number of challenging environmental problems and highly complex social issues, many of which are related to its size and geographically concentrated nature. Increased emphasis on environmental quality has also placed new demands on livestock producers to ensure that their production practices are in harmony with natural environment. In terms of sustainable agricultural systems, ruminants have served and will continue to serve a valuable role. They are particularly useful in converting vast renewable resources from rangeland, pasture, and crop residues or other by-product into food edible for human. With ruminants, land that is too poor or too erodable to cultivate becomes productive. Also, nutrients in by-products are utilized and do not become a waste-disposal problem. In Korea, however, native and dairy cattle production is not consistent with the advantageous roles of ruminant livestock in sustainable agricultural system because imported feed grains become the main basis for cattle raising. At present the ruminant livestock producers are heavily concentrated in and around the urban areas. About 75% of all the nation's cattle herds are kept on the outskirts of urban areas. As a result, the amount of pasture and forage land available per head of cattle is generally small. Furthermore, animals are raised in a cattle shed with high density. This situation is rather unfavorable for the national economic and environmental points of view As nation income increased, the demand for livestock products grew at an unforeseeable pace. But the pasture area involving in current utilization is tended to decrease during recent years. Based on the above figures more than 250,000 ha of pasture ought to be available for the present herd of cattle. It is obvious that these needs can scarcely be met with arable lands. Lands area for the establishment of new grassland have to be found in the hills and mountains which have not yet been used for crop framing or livestock. The development of extensive grasslands in the hill and woodland areas is now a declared aim. The starting point of the present work is the lack of knowledge of forage production and utilization in hill pasture and woodland in spite of indispensable necessity for livestock production in Korea. The importance of pastoral system in hill region and woodland is particularly emphasized in a standpoint of sustainable livestock production. Main chapter comprises the principle and techniques applicable for improving the utilization of hill pasture and woodland. We finally discussed the problems to solve and future works for a successful livestock production in hill and mountainous area in Korea.

도시재생 뉴딜사업 대상지 68곳이 선정되면서 마중물 사업을 통해 지역 이해관계자들이 계획과 관리, 실행을 함께 '지속적으로' 진행할 수 있는 장을 마련하여, 사업 이후에도 지속적인 지역관리가 될 수 있도록 유도하고 있다. 본 연구는 '지속가능한 도시재생'을 위한 활용수단으로서 사회-실험적인 임시점유 시설로서 컨테이너의 활용특성을 분석하는데 목적을 둔다. 공공부문의 임시점유시설로서 컨테이너 활용 프로젝트들에 대한 도시재생 측면의 한계를 밝히고 본질적 의미와 효용성에서 접근한 컨테이너 활용 도시재생의 방향을 설정하기 위한 것이다. 10가지 요소를 국내사례 3개와 와이와이 프로젝트를 비교했을 때, 국내사례는 단순히 트랜드, 경관 및 분위기에 집중하고 있는 한계를 갖고 있으며 운영 프로그램도 단순한 상업 또는 작업공간 센터로서 기존 건축물과 차별성이 없다. 지속가능한 도시재생을 위한 사회-실험적 컨테이너 건축 활용방식을 위한 결론은 다음과 같다. 첫째, 계획주체와 운영주체가 일치되어야 한다. 주체가 상이할 경우, 계획주체의 직접적인 관여가 운영부분의 부재 시 결국 상업성만을 추구하는 편협한 시도에 그치게 된다. 둘째, 한 부지에 대해 활용 용도의 다양화와 집합 분리와 그리고 여러 차례의 실험적 컨테이너의 계획이 필요하다. 셋째, 상업적 성격이 강한 용도를 수용할 경우 도시재생의 방향 및 후속사업과 연속성이 저하될 수밖에 없다. 즉, 단순한 소비나 홍보만의 기능이 아닌 보다 사회-실험적 공공활동이 포함되어야 하며, 이를 통해 추후 공공사업에 반영될 수 있도록 해야 한다.

The Good Agriculture Practice (GAP) program, being established in China, is an optimal way for the sustainable utilization of the medicinal plant and animal resources. Most frequently used Chinese materia medica will be mainly produced from the GAP bases in the future. To assure the successful operation of GAP program, standard operating procedure (SOP) should be implemented for specific plants or animals. Both GAP and SOP include the requirements in many aspects from the ecological environment of cultivation place, germplasm and varieties, seedling and transplant, fertilization, irrigation, and field care, to harvest and process, package, transport and storage. As a complex system, GAP demands strong commitment from the pharmaceutical industry, local administrative involvement, long term R&D support, and years of time of development before a satisfactory result can be achieved.

Cordyceps fumosorosea is an important species in the genus of Cordyceps, containing a variety of bioactive compounds, including fumosorinone (FU). This study was a ground-breaking assessment of FU levels in liquid and solid cultures. The present study focused on the impacts of solid-state fermentation (SSF) using solid substrates (wheat, oat, and rice), as well as the effects of fermentation parameters (pH, temperature, and incubation period), on the generation of FU. All the fermentation parameters had significant effects on the synthesis of FU. In a study of 25 ℃, 5.5 pH, and 21 days of incubation period combinations calculated -to give maximal FU production, it was found that the optimal values were 25 ℃, 5.5 pH, and 21 days, respectively. In a solid substrate medium culture, FU could be produced from SSF. At 30 days, a medium composed of rice yielded the most FU (798.50 mg/L), followed by a medium composed of wheat and oats (640.50 and 450.50 mg/L), respectively. An efficient method for increasing FU production on a large scale could be found in this approach. The results of this study might have multiple applications in different industrial fermentation processes.

This paper is intended to deduce the planning elements of Eco-village through theory contemplation and preceding researches in order to be used as practical data of resident participating Eco-village by contemplating characteristics demonstrated in planning element utilization methods within the village. Resident participating Eco-village aims for residents who will reside in the relevant village to participate from village plans to construction. Unlike other Eco-village, residents of resident participating Eco-village make decisions autonomically through planning direction, planning elements, discussions and meetings, which are uniquely distinctive from other Eco-villages. It appears, however, that analysis on the planning element utilization methods of resident participating Eco-village is inadequate. There are various methods of village resident participation, and the methods cannot rule out the close relationship with planning elements. Hence, programs for resident participation should be devised at the time of village planning. Resident participating Eco-village should suggest measures and guidelines through finding problems in order to implement sustainable and environment-friendly life that prevent a retrograde step.
