This study was performed to determine chemical compositions of dried persimmons stored with plastic film at low temperature and the effect of film packaging on dried persimmons during storage. The moisture contents of dried persimmons were 30 to 36% and alcohol contents were 264 to 318 mg/100g and acetaldehyde contents were 25 to 40mg/100g. Total lipid contents of dried persimmon were 626 to 869mg/100g and oleic, palmitic, linolenic, and palmitoleic acid were major fatty acids in total lipids. Major amino acids were glutamic acid, arginine, cystine and aspartic acid. From the result of storage experiment, non-packed group was that hardness was high as decreased in moisture content. In case of film packed groups stored at 5$^{\circ}C$, self life was longer than non-packed and packed groups stored at room temperature. But, it need to develop available packing material and storage method.

In a distributed system environment based on a service-oriented architecture, separate systems collaborate to achieve the goals of the entire system by using services provided other systems. A service quality violation from using one service can cause runtime system failure in the environment. The existing self-adaptation methods follow fault tolerance mechanism that responds to a failure after a service quality violation. In other words, these methods are limited to responsive action. Therefore, a service-dependability-case based self-adaptation mechanism is necessary to preserve the dependability of the self-adaptive system. This paper demonstrates that the service-dependability-case based self-adaptation mechanism is better than QoS(quality of service)-based self-adaptation with fault tolerance to preserve the dependability of the self-adaptive system. Additionally, this paper suggests a method to present and analyze service dependability by using GSN(Goal Structuring Notation) which is the existing modeling method for the presentation of assurance cases, an action mechanism adapted using an analysis result of service-dependability-cases, a methods of leveraging the service-dependability-case based self-adaptation mechanism by following the service's life cycle, and the framework architecture including the major components and the interactions between the components in the control loop of the self-adaptation process.

Gas hydrate is an inclusion compound consisting of water and low molecular weight gases, which are incorporated into the lattice structure of water. Owing to its promising aspect to application technologies, gas hydrate has been widely studied recently, especially $CO_2$ hydrate for the CCS (Carbon Capture and Storage) issue. The key point of $CO_2$ hydrate technology for the CCS is how to produce gas hydrate in an efficient and economic way. In this study, we have tried to study the characteristic of gas hydrate formation using micro-sized ice through an ultrasonic nozzle which generate 2.4 MHz frequency wave. $CO_2$ as a carrier gas brings micro-sized mist into low-temperature reactor, where the mist and carrier gas forms $CO_2$ hydrate under $-55^{\circ}C$ and atmospheric pressure condition and some part of the mist also remains unreacted micro-sized ice. Formed gas hydrate was average 10.7 of diameter at average. The starting ice particle was set to constant pressure to form $CO_2$ hydrate and the consumed amount of $CO_2$ gas was simultaneously measured to calculate the conversion of ice into gas hydrate. Results showed that the gas hydrate formation was highly suitable because of its extremely high gas-solid contact area, and the formation rate was also very high. Self-preservation effect of $CO_2$ hydrate was confirmed by the measurement of $CO_2$ hydrate powder at normal and at pressed state, which resulted that this kind of gas storage and transport could be feasible using $CO_2$ hydrate formation.

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.

The purpose of this study is to determine social values of self-support enterprises, known as the origin of social economy by using a qualitative research method. Main themes representing social values of self-support enterprises were developed through four sessions of FGI and thematic analysis. First, self-support enterprises embody the value of 'social safety net' by providing workfare for disadvantaged people as well as by operating market-oriented business. Additionally, 'communal spirit', for which self-support enterprises strive, is social value that enables the entirety of self-support enterprises and participants to fulfill non-profit values, reciprocity, and sharing. Lastly, ontological, diachronic, and ecological 'sustainability' of self-support enterprises is a foundational element which creates continuous positive impact on our society. Findings of this study are significant to provide theoretical and empirical evidence for preservation and development of the social economy ecosystem. Based on this, further researches on comprehensive social economy are suggested.

To understand characteristic of preservation of health in Sasang constitutional medicine, 1 first study preservation of health In ${\ulcorner}$Dongyi Bogam${\lrcorner}$, and then study preservation of health in the ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lrcorner}$ particularly Inherent vitality(命脈實數) and Regimen in ordinary life(生息充補之道) which shows early thought of Lee Je-ma. I acquire relation and difference between ${\ulcorner}$Dongyi Bogam${\lrcorner}$ and Dongyi Soose Bowon Sasang Chobongyun${\lrcorner}$, and conclude as follows. 1. In preservation of health ${\ulcorner}$Dongyi Bogam${\lrcorner}$ says Ups and downs of Qi according to degree, tells congenital health and acquired care of health, grades Jin-In, Ji-In, Seong-In, Hyeon-In according to degree of moral culture, and especially emphasizes managing mind which is based on Taoism. 2. In ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lrcorner}$ Dongmu divides human being to Sasangin(Taeyangin, Taeumin, Soyangin, Soeumin) according to Large & small of viscera, and regards as determine lift span and rendition of disease & health according to Inherent vitality which is degree of Small viscera. 3. Inherent vitality of Sasangin is supplemented by Regimen in ordinary life. Because Regimen in ordinary life decreases according to age, Dongmu emphasizes managing mind through an autonomic Knowledge Deed to maintain Regimen in ordinary life. 4. In the way of managing mind ${\ulcorner}$Dongyi Bogam${\lrcorner}$ says Taoist moral culture, but Dongmu emphasized control of knowledge and Deed by Confucian moral culture and the mind of control others through confucian self-control.

This study investigated the self-archiving venues that university faculty members have used, the types of content that they have made publicly accessible on the web, and their rationales for such decisions. The present study was based on the analysis of 480 survey responses and 41 telephone interviews from professors at 17 Carnegie Doctorate-granting universities in the U.S. It was found that faculty members tended to self-archive referred articles on their personal websites or research group websites. This indicated that the faculties perceived peer-review process to be important in self-archiving practices as a quality-control mechanism. The rate of self-archiving in institutional repositories was low, although several interviewees envisioned the potential of the repositories regarding the ability to preserve various types of research works in digital form.

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.
