In this paper, we propose a model to enrich an ontology by incrementally extending the relations through variations of patterns. In order to generalize initial patterns, combinations of features are considered as candidate patterns. The candidate patterns are used to extract relations from Wikipedia, which are sorted out according to reliability based on corpus frequency. Selected patterns then are used to extract relations, while extracted relations are again used to extend the patterns of the relation. Through making variations of patterns in incremental enrichment process, the range of pattern selection is broaden and refined, which can increase coverage and accuracy of relations extracted. In the experiments with single-feature based pattern models, we observe that the features of lexical, headword, and hypernym provide reliable information, while POS and syntactic features provide general information that is useful for enrichment of relations. Based on observations on the feature types that are appropriate for each syntactic unit type, we propose a pattern model based on the composition of features as our ongoing work.

The pilot project for type diversification of self-sufficient support center that convert the centre corporation into social cooperative was introduced in 2015. That aimed to increase the number of participants of self-sufficient programmes and to create more jobs for the working poor through expanding the center's autonomy of usage of budget and arrangement of self-sufficient programmes. This study analyzed the organization transmitting processes and changes of the centers took part in the pilot project, then aimed to suggest the improvement schemes to be helpful for reinforcing positive efforts and removing obstacles in the process converting. The results show that converting into social cooperative is a choice for the sustainability of the centers led by surroundings rather than self-initiated plan. There are some positive changes that are increasing the enterprising spirit and obligation of the center staff. Further more, the cooperation with other community organizations is enhanced based on achieving regional recognition, and support of local governments and the opportunity for new businesses are expanded. However, these are very limited in the regions where social economy is undeveloped. Eventually, we should seek the development schemes of the pilot project considering the reduction of the number of participants in self-sufficient programmes and decreasing of their ability to work, even if some positive aspects are revealed.

The objective of this research is to provide an understanding of how coffee production has been taking place since the coffee industry in Vietnam came out in the global market after Doi Moi. Current research tries to understand how the local households of coffee production adjusts to their production process according to internal and external influences. In order to explore coffee production in the level of local and household units, the structure of coffee production in Dak Lak is first explored in terms of production and sales with the cases from two communes. The examination reveals that general characteristics of coffee crops that would reflect coffee production structure. Further, this study interrogates farmers' response to reflect some direct and indirect influences in recent years. That shows how the elements of coffee production in global market induce a change of coffee production in the study area. Those aspects are analyzed in relation to yearly coffee price fluctuation and diversification. Also, this research explores some of farmers' responses toward the environmental friendly coffee production.

The Studies related to the Gwangju Student Movement which occurred in 1929 have been diversified on research topics since 2018. A number of studies have been conducted on the process of spreading the Gwangju Student Movement abroad. However, those studies show limitations in terms of difficulty in discovering new historical materials and the absence of research methods. Therefore, the researchers have analyzed the process of spreading Gwangju Student Movement abroad as the process of spreading information based on library and information science. The researchers have newly discovered Chinese newspaper records at that times and conducted 2-mode network analysis. The results are as follows: first, 125 Chinese newspaper records were discovered from 16 kinds of newspapers and 104 articles of them were newly discovered; second, the researcher found that there were earlier articles than the first claimed by previous researchers in their studies; third, Newspapers in Beijing, Sacheon, Shanghai, Tianjin, and Honam regions in China mainly reported the first and second joint demonstrations in Seoul and Gwangju. The significance of this study is to expand and diversify the research on the Gwangju Student Movement through network analysis.

The globalization of the economy has strengthened competition in all industries. Facing an intensely competitive environment, the firm's choice of location is one of the most important strategies in enhancing its competitiveness. This paper aims to examine the locational changes and the spatial restructuring of suppliers firm with regard to modularization and customer diversification which result from the process of assembler's restructuring after the financial crisis. Some experimental findings which have been identified throughout this study can be summarized as follows: First, a number of suppliers has been located in the southern Seoul metropolitan area and northern Chungcheong area. And Hyundai's suppliers has been enlarged in the Seoul metropolitan area and Kia's in the Southeastern area. Second, suppliers who transact with several assemblers(network trade) tend to be more dispersed, but dedicated(exclusive) suppliers are more concentrated on assembly plants. Also it was confirmed that 'JIS(Just In Sequence)' system which is more detailed than 'JIT(Just In Time)'system has been used. Third, it was Prominent that suppliers are internalizing in order to reach economies of scale compare to assemblers are externalizing.
