Complex traits are determined by the combined effects of many loci and are affected by gene networks or biological pathways. Systems biology approaches have an important role in the identification of candidate genes related to complex diseases or traits at the system level. The gene network analysis has been performed by diverse types of methods such as gene co-expression, gene regulatory relationships, protein-protein interaction (PPI) and genetic networks. Moreover, the network-based methods were described for predicting gene functions such as graph theoretic method, neighborhood counting based methods and weighted function. However, there are a limited number of researches in livestock. The present study systemically analyzed genes associated with 102 types of economic traits based on the Animal Trait Ontology (ATO) and identified their relationships based on the gene co-expression network and PPI network in cattle. Then, we constructed the two types of gene network databases and network visualization system (http://www.nabc.go.kr/cg). We used a gene co-expression network analysis from the bovine expression value of bovine genes to generate gene co-expression network. PPI network was constructed from Human protein reference database based on the orthologous relationship between human and cattle. Finally, candidate genes and their network relationships were identified in each trait. They were typologically centered with large degree and betweenness centrality (BC) value in the gene network. The ontle program was applied to generate the database and to visualize the gene network results. This information would serve as valuable resources for exploiting genomic functions that influence economically and agriculturally important traits in cattle.

This study aims to discover the characteristics of Sino-South Korean cross-border small-scale trade, which involves various players. Through this characteristics, this study ultimately intends to identify an operational mechanism of Sino-South Korean cross-border small-scale trade by investigating social capital as mobilized by small-scale traders. The results of this study can be expected to help understand how small-scale merchants address the uncertainty or risks surrounding their trade. Although it is an informal economic activity, the cross-border small-scale trade between South Korea and China is related to issues of the formal economy, such as job creation, benefits for local economies, and profit-seeking. Owing to this characteristics, small-scale trade is being conducted with the connivance of, or even with the tacit support from formal organizations, including municipal governments, customs, corporations, and shipping companies. Like trade in other countries, Sino-South Korean cross-border small-scale trade also requires different types of social capital, such as family networks, ethnic networks, social networks, and trust.

Many consumption goods, most notably in network markets including the telecommunications industry, exhibit network externalities. For that reason, standardization is the tore Issue in network markets with powerful positive feedback. firms in the telecommunications industry compete intensively against one another to build on early lead due to w inertia and network externalities. Therefore, a firm's strategies err very important in standards competition. In this paper, we'll examine the patterns of standards competition and cooperation, anti a variety of firms' strategies in the telecommunications industry. And then, we'll examine the trend of the change from standard competition to standard cooperation. After that, we'll suggest the national policies for the preemption.

This paper is concerned with the relationships between large firms with global reaches in their markets and subcontracting firms, mostly small and medium-sized firms. It then attempts to focus in more detail on the dynamic relational dimensions between the two. In doing so, we draw upon the secondary data and the results of interviewing survey with some senior managers. The empirical study shows that the localisation of subcontracting networks have been increasingly reinforced thanks to the increasing tendency of vertical disintegration by LC. However, it is identified that there is a tendency that local subcontractors are specialised in producing relatively low value-added and low technology-intensive electronic parts/components. Based on these results, the author suggests the implications of regional economic development in the context of innovation and learning.

The purpose of this study is to present the necessary success strategies for the social economy ecosystem and social enterprise stakeholders by empirically examining the structural relationship of factors that affect the sustainable dual performance of social enterprises. Through previous studies, hypotheses and research models were established for the performance factors of social enterprises, and hypothesis testing was performed using PLS-Structural Equation Modeling on 92 sample data collected from the survey. As a result of the analysis, it was found that the social mission, customer orientation, and social network set as performance factors all had a significant positive (+) effect on social performance. In addition, social performance had a significant (+) effect on economic performance by mediating customer orientation and social network excluding social mission, and it was found that the business model strengthened this relationship. In addition to the theoretical significance of demonstrating the structural influence of social enterprise performance factors through this study, practical implications can be found in that it suggests factors that social entrepreneurs should focus on for growth and performance creation.
