서비스 지향 시스템 환경에서는 하나의 독립된 시스템이 다른 시스템에서 제공하는 서비스를 사용함으로써 시스템의 목표를 달성한다. 이러한 시스템 환경에서는 사용중인 서비스의 품질 저하가 실시간으로 시스템 장애를 유발할 수 있다. 기존 자가 적응 방법들은 서비스의 품질 저하 발생 후 대처하는 fault tolerance 방식을 따르고 있기 때문에 서비스 품질 저하로 인한 피해 발생을 예방하지 못한다. 따라서, 자가 적응 시스템의 신뢰도를 보존하기 위해서는 사용 중인 서비스를 fault tolerance 방식의 품질 기반 적응이 아닌 서비스 안정성 케이스를 기반으로 자가 적응해야 한다. 본 논문에서는 기존의 보증 속성 표현 방법인 Goal Structuring Notation 모델링을 활용하여 서비스 안정성 케이스를 표현 및 분석하기 위한 방법과, 서비스 안정성 케이스 분석 결과에 따른 적응 조치 방법, 서비스 생명주기에 따른 서비스 안정성 케이스 기반 자가 적응 메커니즘 적용 방법, 서비스 안정성 케이스 기반 자가 적응을 위한 프레임워크 아키텍처를 제안한다.

Aroma therpay in the western classical medicine is compared with the mechanistic paradigm of Newton physics which is the foundation of western modern medicine. It is the therapy whose basic principle is very similar to the basic concepts of oriental medicine lasting thousands of years. We know that parts of their therapies are explained by Yin-Yan and five elements in Oriental Medicine. In the modern western medicine, as preventive medicine is becoming more and more important and moreover, health promotion and self healing care is being emphasized, Maintenanayce which is the oriental preventive medicine, acts in concert with the concept of New Age of Science and provides a way for the Oriental Medicine of the future. The health promotion and self healing care is similar to the thought of Maintenanayce in Oriental Medicine. Oriental Medicine has provided the concept of preventive ehaling care for a long time and built the foundation of the department of Maintenanayce. Among these method of Preservation of Health, We could find that of using fragrance throuth the several references. By comparing the department of Maintenanayce in oriental preventive medicine with the books and papers about aroma therapy, used in the fields of naturalpathy medicine, alternative medicine, and complementary medicine in the west, and by analyzing them, centering around references, to see whether they are reasonable and corresponding, the following conclusions have been reached. 1. We could see that aroma therapy of oriental preventive medicine could be applied to the fields of health promotion and self healing cure, recently appearing in the world of health medicine, as a modern way of Preservation of Health(養生). 2. We could see that western traditional aroma therapy take important position in alternative medicine and complementary medicine, and it could be developed as the transitional field of medical cure for the interchange between western and eastern medicine. 3. We could see that aroma therapy is not totally unknown therapy and there is some points of similarity in the traditional references of oriental medicine. Also, it is considered that the aroma therapy has a possibility of coming the front as an general therapy among various therapies. 4. aroma therapy will be actively applied to many fields such as oriental psychiatry, internal medicine of the respiratory system, pediatrics, oriental nursing, oriental dermatologic beauty, and preventive medicine. Therefore, we have a view that the combination between aroma therapy and oriental medicine will be fairly valuable to study as the general and transtional middle step on which it will prepare the situation of oriental medicine's reimportation from the west and we establish a bridgehead to export the oriental medicine.

This study analyzed characteristics of natural and human environments in Chuncheon's Gongji stream, and suggested nature-friendly planning strategies for self-purification of water quality, biodiversity improvement and conservative waterfront recreation. The environmental analysis included streambed structures, floodplain soils, water quality, vegetation, wildlife, and human facilities. Natural colonization of vegetation for the middle section of the study stream was obstructed by a straightened concrete revetment of baseflow channel, and vehicle movement and concrete parking lots across the floodplain. These human disturbances also deteriorated the naturalness of the stream landscape and limited habitation of bird species. However, natural sedimented wetlands in half of the channel width for the lower section of the stream contributed to a desirable vegetational landscape and greater bird occurrence. Based on BOD measurements, water quality of the stream fell under class $II{\sim}III$ of the stream water-quality standard, but it was worse around sewage outlets due to incomplete sewage collection especially during the dry season. Dominant fish species included typical inhabitants of good water-quality streams that are tolerant of adverse habitat changes. Nature-friendly planning strategies were established based on analysis of the environmental characteristics. They focused on not merely spatial zoning and layout divided into four zones - preservation, partial preservation, conservation and use -, but close-to-nature channel revetment techniques, natural water-purification facilities, biotope diversification, and water-friendly recreation and circulation. Strategies pursued both renewal of stream naturalness and hydraulic stability of streamflow by minimizing transformation of natural channel micro-topography and biotope, and by reflecting natural traces of streambed structures such as revetment scour and sedimentation.

Natural gas hydrate (NGH) is emerging as a new eco-friendly source of energy to replace fossil fuels in the 21st century. It is well known that the Natural Gas Hydrate contains large amount of natural gas about 170 times as much as its volume and it is easy to be stored and transported safely at about $-20^{\circ}C$ under atmospheric pressure due to so called "self-preservation effect". The option of gas transport by gas hydrate pellets carrier has been investigated and developed in various industry and academy. The natural gas hydrate pellet carrier is on major link in a potential gas hydrate process chain, starting with the extraction of natural gas from the reservoir, followed by the production of hydrate pellets and the transportation to an onshore terminal for further processing or marketing. In recent years, Korean project team supported by Korean Government has been working on the development of NGH total systems including novel NGH carrier since 2011. In order to increase the knowledge on the NGH pellet carrier developed and to understand the major hazards that could have significant impact on the safety of the vessel, this paper presents and evaluates the pros and cons of cargo holds, loading and unloading systems through the analysis of current patent technology. Based on the proven and well-known technologies as well as potential measures to mitigate sintering and minimize mechanical stress on the hydrate pellet in the self-preservation state, this study presents the conceptual and basic design for NGH carrier.
