  • MPEG-21 defines a digital item as an atomic unit lot creation, delivery and consumption in order to provide an integrated multimedia framework in networked environments. It is expected that MPEG-21 standardization makes it Possible for users to universally access user's preferred contents in their own way they want. In order to achieve this goal, MPEG-21 has standardized the specifications for the Digital Item Declaration (DID). Digital Identification (DII), Rights Expression Language (REL), Right Data Dictionary (RDD) and Digital Item Adaptation (DIA), and is standardizing the specifications for the Digital Item Processing (DIP), Persistent Association Technology (PAT) and Intellectual Property Management and Protection (IPMP) tot transparent and secured usage of multimedia. In this paper, we design an MPEG-21 terminal architecture based one the MPEG-21 standard with DID, DIA and DIP, and implement with the MPEG-21 terminal. We make a video summarization service scenario in order to validate ow proposed MPEG-21 terminal for the feasibility to of DID, DIA and DIP. Then we present a series of experimental results that digital items are processed as a specific form after adaptation fit for the characteristics of MPEG-21 terminal and are consumed with interoperability based on a PC and a PDA platform. It is believed that this paper has n important significance in the sense that we, for the first time, implement an MPEG-21 terminal which allows for a video summarization service application in an interoperable way for digital item adaptation and processing nth experimental results.

  • In Korea, an olive flounder is very popular fish food item. However, due to the increasing human population, the present catches of the olive flounder may not be sufficient to satisfy the present demand. To increase the supply of the olive flounder, aquaculture has been begun. An interest in the aquaculture of the olive flounder has been increased recently because of its characteristics of good growth and high price in the market, However, the productivity of the olive flounder aquaculture depends on economic inputs such as fuels, facilities, and labor. The rapid growths of the olive flounder aquaculture and the concerns about economic and ecological sustainability have focused peoples attention on the aquaculture industry. In this study, an energy systems model was built to simulate the variation of sustainability on the aquaculture of olive flounder, The results of simulation based on calibration data in 1995 show that olive flounder production yield and asset slowly increase to steady state because of the law of supply and demand. The results of simulation based on the variation of oil price show that the more increase the oil price, the more decrease the olive flounder economic yield and asset. Energy sources required for systems determine the sustainability of systems. Conclusionally, the present systems of the olive flounder aquaculture should be transformed to ecological-recycling systems or ecological engineering systems which depend on renewable resources rather than aquaculture systems which depend on fossil fuels, and be harmonized with the fishing fisheries by the sustainable use of renewable resources in the carrying capacity.

  • As the discussions on sharing research data prevail by the chance of the inauguration of the International Open Data Charter, research support organizations in the United States, the United Kingdom, and Japan are encouraging researchers to deposit their findings in a credible repository. Humanities and social sciences field, in which research data sharing culture and storage infrastructure are immature compared to life science and natural science, also needs to establish and operate a reliable storage infrastructure to guarantee the continuous access and utilization of data. This study analyzed the overall operational status of 305 subject repositories registered in re3data for the humanities and social sciences and clustered them according to the operational level using 5 indicators. As a result, 70% of the population were identified as universal clusters, and 20% of the excellent cluster was found to have the largest number of linguistic fields and the German-operated. In addition, this study confirmed through correspondence analysis that there is a relation between the sub-theme fields of humanities and social sciences and the types of data to be archived. The history and art domians are related to images, and social studies are related to statistical data. Linguistics has also been analyzed to be related to audio, plain text, and code.

  • A new variety of tall fescue (Festuca arundinacea Schreb.) named 'Greenmaster4ho' was developed during the cultivation year 2010-2017 at Grassland and Forages Division, National Institute of Animal Science, Rural Development Administration, Cheonan, Korea. In order to produce this new variety, 5 superior tall fescue lines including 12XFa07, 12XFa15, 12XFa24, 12XFa46, and 12XFa48 were polycrossed. The new variety Greenmaster4ho was evaluated in field test (Cheonan, Pyeongchang, Jeju, and Jinju) for determining the agronomic growth characteristics and forage production capability during 3 years (2015-2017). The dry matter yield (16,236 kg/ha) of Greenmaster4ho was 5 % higher than Fawn, but the nutritive value as forage crops was not significantly different with Fawn. Development of new tall fescue variety with excellent adaptability to changing unfavorable environment would be useful for forage cultivation and yield in Korean environment.

  • It is very important to understand the factors affecting the occurrence of vacant houses in research on them. The purpose of this study is to analyze the factors affecting the rural vacancy occurrence. This study set 121 research areas and selected eight independent variables (Aged house rate, housing transaction rate, house diffusion ratio, local extinction index, net migration rate, regional aging index, the ratio of the number of employees to population and financial independence rate) and one dependent variable (vacant house rate). As a result of the study, first, both Model 1 for the entire general agricultural fishing village area and Model 2 for the county (gun) area were statistically significant, there was no problem with the independence of residual. Second, local extinction index and aged house rate had a statistically significant positive (+) relationship in both Model 1 and Model 2. Third, diffusion ratio of house had a statistically significant positive (+) relationship only in Model 1, and housing transactions rate had a statistically significant negative (-) relationship in Model 2. The implications of the study were drawn as follows: First, the increase in the house diffusion ratio without growth in households and population suggests the increase of the probability of the vacancy occurrence in the area, and the higher the aged house rate, the higher the probability of the vacancy occurrence. Second, for the revitalization of housing transactions, it is necessary to have an investment inflow in the area for mid- to long-term development. Third, local extinction index has a significant relationship with vacant house rate, it is necessary to introduce a local revitalization policy from a long-term perspective for the permanence of the area.

  • Max Weber claimed that the clans as a self-sufficient community in traditional China had limited market development. His statement can be applied to the lineage groups of $Chos{\breve{o}}n$ dynasty, however, it also could be criticized as an example of oversimplifying clans. Starting from this question, in this article, I examined the lineage movement of the P'ap'yong Yun's Nojongp'a branch. Through this research, I tried to investigate the reality of the lineage group communities of $Chos{\breve{o}}n$. My issues are following. First, the Nojongp'a clan promoted the solidarity movement of their lineage in the name of practicing human morality, which belonged to their family learning. Second, the Nojongp'a clan made preparations for their own 'righteous rice fields and grains', through which they tried to establish the base structure for the clan activities. This, however, had its own limitations in aiding the starved suffering from famines and did not last long. Third, the lineage could not function as a community for living that was actively involved in the reproduction of life, and was not an exclusive self-sufficient community, either.

  • This study focuses on the case of the National Museum of Modern and Contemporary Art, Korea (hereafter MMCA) that has faced the issue of securing autonomy as an art institution in association with the neoliberal logic of economy as part of globalization. The MMCA was opened with limited operational autonomy due to the government's development-driven national system and bureaucratic perspective. Since being selected as an institution subject to a range of restructuring consequent to the IMF crisis in 1997, the MMCA is being assessed for its operational autonomy since then. This paper examines the socio-cultural background of the implementation of the Korean type of 'Executive Agency' and 'Non-Departmental Public Body'. Furthermore, regardless of the result of either implementation or withdrawal after the projects, this paper explains how these administrative reforms lead the conflicts between stakeholders, which would promote the MMCA's autonomy. As a result, the institutional restructuring process based on the neoliberal perspective might result in the operational dilemma that must simultaneously fulfil the publicness in a different context. Moreover, unlike the original intent to establish a performance-based system based on the principle of competition while minimizing government intervention, this study illuminates that the influence of the nation(or government) as the actual agent of the projects may become permanent. It implies that since the establishment and development project of MMCA has initialized the concept of statism based on legal authority, the operational autonomy of the MMCA which is premised on the reinforcement of expertise and publicness cannot be prioritized over the direction and control of the government.

We approached grounded theory to subject. Twenty biological parent's of foster child participated this research. The Data were collected by in depth-interview and documents. The authors analyzed the data according to frame that proposed Strauss and Corbin(1998). The results as follows: In open coding 143 concepts, 34 subcategory, 13 category. In axial coding the causal conditions were 「self-devaluation」, 「self-stigma」, 「social prejudice」. and the phenomenon were 「life as surplus being」, 「revolving around the world」, and the contextual conditions were 「collapse of life base」, 「rustical fatalism」. The intervention conditions were 「operation of support system」, 「instinct of maternity」. The action/interception strategy were 「closing of single eye」, 「pussling of scattered piece」. The consequence were 「fixations of abandonment」. 「resoaring to the world」 The authors proposed the core category as 「go over the wall of world burdening liabilities of being」. The authors classified patricians life type as 「challenging type」, 「status quo type」, 「escaping type」, Finally, we proposed the practical method for support restoring family the world」, foster care child's biological parents.

  • This study was conducted to derive a Korean model that can permanently maintain and develop Korea. After analyzing Korean society, especially modern Korea, which was the foundation of the founding of the Republic of Korea, a Korean model that can lead Korean society as a sustainable society in human society was derived. The situation of Korea and Koreans was analyzed from a fundamental level. We analyzed the root causes of deepening division and conflict and vague concepts of freedom and justice, and presented a Korean model of the Republic of Korea based on the founding ideology and constitutional spirit of the Republic of Korea to solve these problems. The necessary conditions for being a Korean were derived from the founding ideology and constitutional spirit of the Republic of Korea, the indigenous ideology of Korea, and the fashion and lifestyle of Koreans, derived. In addition, basic axioms for the Korean model were presented, and the structure of the Korean model was designed based on this. The Korean model is presented so that Korean society can lead the human society and be happy for a long time. Reflecting the results of in-depth analysis of the ideological foundations of modern Koreans, a new long-term sustainable structure for Koreans with various ideologies to live well together was proposed. The new Korean model was named the service-oriented Korean model. This is because it is a model centered on thorough checks and balances between all opponents, because it is a multidimensional dynamic Korean model rather than a simple linear one-dimensional Korean model, and because it is a Hwajaengtaeguk model that accurately expresses the identity of Koreans. It was proposed as a model for the sustainable development of Korean society. A follow-up study on specific Korean education programs is needed in the future.
