The purpose of this study is to find out suggestions for government policy and expansion of consumption of environmental-friendly agricultural products(EFAP). For this purpose, we did research on purchasing pattern of EFAP and understanding of government environmental-friendly agricultural policy. First, the purchase of EFAP has been increased, because EFAP is safer. Consumers prefer department store because it is easier than any other marketing. Difficulties which consumers are facing when they purchase EFAP are price and credibility and small number of stores. Most favorable item is vegetable and the price of rice which consumers are willing to pay is really high. Second, not many consumers do recognize the label and system of EFAP. Third, most famous authentication institution agricultural products quality management service and other institutions are not recognized. Consumers recognize the certificate of origin. The government policy for safe food consumption is to intensify government supervision on foods. Suggestions from these results are as follow: First, the urgent problem to expand consumption of EFAP is credibility of EFAP. To make consumers trust EFAP, these are considered as useful solutions, i.e. recall, quality management service, standardization, and better quality. Second, government should be continue public relation, education and supervision of EFAP. Third, quality management should be continued. Not only central government but also local quality management institutions should continue quality management service. Last, local government should help farmers of EFAP to solve the difficulties of marketing.

We present a GPS-derived regional ionosphere model, which estimates Total Electron Content (TEC) in a rectangular grid on the spherical shell over Korea. After dividing longitude and latitude over Korea with 1$^{\circ}$$\times$1$^{\circ}$ spatial resolution, the TEC at the vertex of the grid was estimated by the Kalman filter. The GPS data received from nine nationwide GPS stations, operated by Korea Astronomy Observatory (KAO), were used for this study. To reduce inherent noises, the pseudorange data were phase-leveled by a linear combination of pseudoranges and carrier phases. The solar-geomagnetic reference frame, which is less variable to the ionosphere movement due to the Sun and the geomagnetic field than an Earth-fixed frame, was used. During a quiet time of solar activity, the KAO's regional ionosphere map indicated 30-45 Total Electron Content Unit at the peak of the diurnal variation. In comparison with the Global ionosphere Map of the Center for Orbit Determination in Europe, RMS differences were at the level of 4-5 TECU for five days.

Localized unprecedented torrential rain and heavy rainfall cause repeated damages and make it difficult to detect and predict the landslide caused by heavy rainfall. To analyze the landslide characteristics of Inje area this study used satellite images photographed after the occurrence of landslide caused by the typhoon Ewiniar occurred in July, 2006, and for GIS analysis purpose, interpreted the satellite images (SPOT5) visually to digitize into developing parts, water traveling parts and sediment parts. For analysis of spatial characteristics, landslide areas obtained from visual interpretation of digital map, 3rd & 4th forest vegetation maps and detailed soil map and grids were overlaid and analyzed. As a result, in regard to topographic features, landslide occurred at places, of which average slope is $26.34^{\circ}$, had south, south-east, south-west aspects and average altitude of 627m. From hydrological analysis, it was found out that water traveling area rapidly spread approaching water traveling area and sediment area. From forest type analysis, it was found out that landslide occurrence was high in pine woods, and in terms of girth class attribute, landslide occurred in small-sized woods, in which the crown occupancy of trees that have the diameter at breast height, 6~16cm, was greater than 50%. From the analysis of soil series, landslide areas constitute 37.85% of OdF and 37.35% of SmF, which had sandy loam soil and excellent drainage capacity. Through this study, landslides in Inje area were characterized and SPOT5 images of 2.5m resolution could be used. But there was a difficulty in determining water traveling parts adjacent to urban area.

The characteristics of deposits formed by the Daejon-cheon and Soobuk-cheon, dissecting the mountains such as Byungpung Mt. and Samin Mt. in western part of Damyang county, Jeonmam province. Results from field survey and bore hole logging by KIGAM are used in interpreting depositional environment, in this study. By the result of deposits near of the channels Daejon-cheon and Soobuk-cheon, and main channel of Youngsan River, the depth of sediment layers in this area is 4~7m, far thinner than formerly estimated. Weathered material of local rocks forms the base of the sedimentary layers. It can be assumed that the location channel of the Youngsan river has been stable ever since the start of the sedimentary events. Sediment particles of tributaries are angular than those of Youngsan River. Particles are larger and sorting is poor. It is interpreted as mount flash flood deposits. Main sources of sediments at the valley bottom or deposition dominated area are the terrace deposits or slope deposits over the gentle foot-slope or front of surrounding mountains. Some particles show polygonal cracking on the surface originated from the strong chemical weathering, while most of these has high angularity. It means various geomorphic processes operate to produce and transport the particles in this area.Isolated hills within the sedimentary plains are made with weathered materials of local bedrock. In the case of foot-slope of the hills, thin sedimentary layers are found. So it can be concluded that surface features of deposition zone of the Daejon-cheon and Soobuk-cheon is formed by the filling of lower part of the valley and its feature partly controlled by the relief of the weathering front.

Fandom is a meaningful social phenomenon that represents a significant dimension of contemporary Korean youth culture. Previous research, however, has considered fandom as a deviant activity that is negative in nature, and there is scant research on the positive effects of fandom activity. This study examined the effects of off-line and on-line fandom activity participation on adolescents' academic time management capability. Data were collected from three waves (2010, 2012, and 2014) of the Korean Children and Youth Panel Survey (middle school cohort; N=2,206 at baseline). Results from the multi-level growth curve analysis were as follows. First, more than half of the adolescents reported participating in fandom activities, and the majority of them participated in both online and offline activities. Second, adolescents' academic time management capability improved over time. Third, both off-line and on-line fandom activity participation was positively associated with adolescents' academic time management capability at the baseline (first year of middle school). The size of this relationship, however, decreased over time (from middle school to high school). This study presented the importance of appropriate guidance by adults to develop and promote the positive aspects of fandom activity, and highlighted the need for further research that focuses on the positive aspects of fandom activities.

This paper aims to apply our research and theorization on arts entrepreneurship to entrepreneurs active in the arts and cultural sector. Our goal is to develop proposals for practical actions that can support both arts entrepreneurs and supportive arts advocates. Using Action Research methodology, we hosted and facilitated two workshops with selected groups of arts entrepreneurs. Prior to the workshops we designed a questionnaire, based on the competency theory, to assess the qualities and characteristics of the participants. During the workshops we conducted surveys, interviews, and made observations in order to further understand the knowledge, experiences, motivations, capabilities, and attitudes necessary to successful arts entrepreneurship. We also conducted in-depth follow-up interviews with participants as a cross-check. We found that most of the participating arts entrepreneurs had a low understanding of the technology required for effective arts entrepreneurship, which has resulted in insufficient managerial support for artistic innovation. In addition, we found that participants lacked the skills and clear vision to construct a viable economic engine for their organization. Nevertheless, in light of the considerable strengths and high levels of enthusiasm and commitment participants evinced, we believe that their deficits can be corrected with education and training. Thus, we conclude by discussing the path forward and outlining a proposal to develop an innovative educational program on the daily operations of arts management that emphasizes applied technology and creating financial sustainability.

This paper examines how Dasan Jeong Yak-yong developed self-healing and his perspective of happiness during the hardest point of his political and social career. Just after the death of King Jeongjo (正祖, reign. 1766-1800) the arrest and persecution of those who accepted Christian knowledge from the West began. Among them were Jeong's family members and friends. Jeong, who had learned but had not accepted Christianity as a religious belief, was exiled to Ganggin 康津 in southern Jeolla Province where he was to spend the next 18 years. The two things that helped Jeong through his exile were the Book of Changes 易經 and his commitment to the study of Confucian thought, political, and social reforms. His life-long commitment to writing and his progressive understanding of the principle of changes of the universe in the Book of Changes, represented processes of self-healing and cultivation, depriving Jeong of self-pity and enabling him to attain the highest level in self-realization. According to Jeong, there are two kinds of happiness; "secular happiness" (yeolbok 熱福) related to power and wealth, and "pure happiness" (cheongbok 淸福), a free and idyllic life. For Jeong, the latter was more valuable than the former. Jeong believed that life pursing ethical virtues only could bring authentic joy to people. Furthermore, his devotion to the issues of systematic, social reforms was out of his desire to bring the public happiness by "practical learning", silhak 實學.

The purpose of this study is to raise the necessity of an alternative awareness toward economic activities as the work form of social participation by the elderly and their corresponding educational tasks. For this aim, the concept of Japan's 'rewarding work participation' and its practical cases have been examined. As a study method, the characteristics of Japan's state and local government elderly policy projects have been examined through literature research. Next, the cases of the elderly having established an autonomous company and practiced Ogawanosho Oyakimura were researched based on on-site visits and interviews. As this study has suggested that the economic activities of the elderly have to be carried out from the perspective of successful aging and these activities have been conducted through 'rewarding work participation', the following features have been clarified. First, a converted image of the elderly is necessary. The elderly do have the experiences worthy of social utilization. Second, the educational and managerial policies which turn the elderly's experiences into social values are necessary. Third, a flexible awareness toward the corresponding works of the elderly is needed. In other words, the works which have reflected mentally solitary tendency and social discontinuity features of the elderly and taken into account the demands of the elderly generation who desire to become an influential and meaningful existence are necessary. Thus, future elderly education need to come up with the policies and practices toward work education from the viewpoint of rewarding work participation.

The purpose of this study was to review the Gentrification and Development Index in terms of domestic and foreign gentrification. Based on the important indicators of the Gentrification index through previous research, the four evaluation areas were divided into structure and subject, production and consumption, supply and demand, and capital and culture. Looking at the importance of each area, the production and consumption aspects were highest as the important index of the occurrence of gentrification, followed in order by the supply and demand, the structure and subject, and the capital and culture order. From the detailed factors, the report revealed the changes in sales to structure and subject matter, increases in franchises to production and consumption, rises in rent to supply and demand, and transient population to capital and culture to be important items. In addition, an analysis of the gentrification occurrence indicators in urban regeneration project areas revealed high weight in terms of production and consumption, supply, and demand, including the increased franchises, one-person start-ups, higher rents and higher real estate values. In other words, the occurrence of gentrification in urban regeneration areas produces the largest portion of the increases in franchises and rent. Therefore, step-by-step measures are needed through monitoring.

Due to the problems associated with the aging of industrial complexes, research on the decline of industrial complexes is being conducted. In the case of decline, it is necessary to not respond immediately, but with a crisis, it is necessary to minimize the impact on the industrial complex through preemptive responses to the external environment and internal changes. Therefore, it is necessary to develop a crisis index that can systematically predict and evaluate changes in the industrial complex. In this research, a method for extracting the crisis index of an industrial complex is developed. We derive performance measures for developing the crisis index, deriving the relative importance of performance measures based on the analytical hierarchy process. Because units of performance measurement are different, a normalization method is developed to sensitively reflect change. Based on the relative importance and normalized values of the performance measures, the crisis index of the industrial complex is developed and applied to a national industrial complex in order to verify its applicability.
