Purpose - The main feature of this study is understanding of the vendor's opportunism on the collaboration context between buyer and vendor from the buyer's viewpoint with resource dependence theory. A number of studies on opportunism have focused on opportunistic definitions and its theoretical studies. Other researches emphasize the importance of governance in ways that reduce opportunism. We think that this research could be filled with the lack of previous studies. Research design, data, and methodology - In order to accomplish research purpose, four hypotheses have been established based on the framework of resource dependence theory and previous studies. And we have used 599 survey data jointly collected by Korea Productivity Center and the Ministry of Trade, Industry and Energy. To verify these hypothesis, we have conducted multiple regression analysis with SPSS 23.0. Results - The vendor 's opportunism decreases as mutual trust with buyer becomes higher. However, as the degree of dependence of buyers on vendor resources increases, vendor's opportunism increases. And monitoring vendor's capacity has a moderating effect with buyer resource dependency to vendor's opportunism. Conclusions - This study suggest there are two options to decrease vendor's opportunism. Increasing mutual trust or decrease dependence on vendor's resources. Also, monitoring suppler's capacity could be effective when vendor's resource dependence is high.

In this paper, we apply fuzzy theory in a discrete choice Contingent Valuation Method(CVM) in order for dealing preference uncertainty problem. Fuzzy membership function is used in an empirical analysis to estimate the willingness-to-pay(WTP) for the preservation of the endangered Asiatic Black Bear in Korea. The estimated WTP was about 9,090 Korea Won per household with 78 percent of confidence level. The advantage of applying fuzzy theory in the valuation method could be found in its ability to measure the confidence level of the estimated WTP.

The purpose of this study is to establish fundamental knowledge on the experience for building resource system using the social networks within the community. This study used a social capital perspective and the grounded theory method based on Strauss and Corbin(1998) and Corbin(2004). Interviews were conducted with 14 Korean social workers (general managers and assistant managers) at community welfare centers who have developed resources by using the social networks or social relations for more than 3 years. In creating autonomy and sustainability of community, there are four types of social worker's efforts in building resource system within the community: 'restoring norms of reciprocity', 'developing citizen's capabilities', 'mobilizing resources through community organizations', and 'utilizing external resource-networks'. These results are contribute to developing theory on social welfare resources using community networks according to characteristics of a community.

The present study aims to examine the role of market orientation as an international partnership property. This property, labeled export-venture market orientation, is at the inter-firm level and is related to the new market development (NMD) activities of export-ventures. Specifically, this article is to define the export-venture market orientation; to argue that it is a major factor in NMD export-venture success; and to argue that the resource-advantage (R-A) theory of competition can provide a theoretical foundation for this concept and explain its contribution to export-ventures' international expansion success. This manuscript is conceptual in approach. In their efforts to strengthen relationships, export-ventures may tend to focus so much time on the partnership factors that they miss market opportunities. As a spanning process, NMD should be informed by both external and internal activities. In an export-venture, market orientation helps guide NMD activities from outside to inside and vice versa. As a dynamic and disequilibrium provoking process, the R-A theory can theoretically ground the concept of export-venture market orientation and explain its role in NMD export-venture success. The current study contributes to business marketing theory in three ways: it extends the concept of intra-organizational market orientation to an inter-organizational context; contributes to understanding the role of idiosyncratic resources in export-ventures; and theoretically explains the concept of export-venture market orientation. The present study is the first to extend the concept of market orientation into inter-organizational NMD framework and to examine the role of export-venture market orientation in NMD export-venture success.

The traditional approach of fixed spectrum allocation to licensed networks has resulted in spectrum underutilisation. Cognitive radio technology is envisioned as a promising solution that can be used to resolve the ineffectiveness of the fixed spectrum allocation policy by accessing the underutilised spectrum of existing technologies opportunistically. The implementation of cognitive radio networks (CRNs) faces distinct challenges due to the fact that two systems (i.e., cognitive radio (CR) and primary users (PUs)) with conflicting interests interact with each other. Specially, in self-organised systems such as ad-hoc CRNs (AHCRNs), the coordination of spectrum access introduces challenges to researchers due to rapid utilisation changes in the available spectrum, as well as the multi-hop nature of ad-hoc networks, which creates additional challenges in the analysis of resource allocation (e.g., power control, channel and rate allocation). Instead, game theory has been adopted as a powerful mathematical tool in analysing and modelling the interaction processes of AHCRNs. In this survey, we first review the most fundamental concepts and architectures of CRNs and AHCRNs. We then introduce the concepts of game theory, utility function, Nash equilibrium and pricing techniques. Finally, we survey the recent literature on the game theoretic analysis of AHCRNs, highlighting its applicability to the physical layer PHY, the MAC layer and the network layer.

The present study investigated psychological closeness between grandmothers and their grandchildren and functional aspects of grandmothers in the Korean family. 219 grandchildren, fifth and sixth grade children of 5 elementary schools in Seoul completed questionnaires. The results showed that grandmothers in Korea are categorized in an institutional role characterized by status and role performance. Among social role theory, resource theory and system views, the social role theory best explained psychological closeness between grandmothers and grandchildren.

The purpose of this study are as follows : First, This study conceptually provide an insight of reasons that organizations seek to create, acquire, store and distribute knowledge at the level of an organization and of process how they can transform or evolve to knowledge based organizations. Second, this study confirms examine what theories can be used to knowledge management, how such theories can be useful to analyse knowledge management and provide a theoretical foundation for knowledge management research. Applied to the theories of knowledge based and resource based view and institutional theory, the essence of knowledge management confirms that the organization finds job-related knowledge and know-how retained by individual of organizational members systematically and shares common knowledge within the organization and explains knowledge creation, multi-dimensional knowledge transition and share in all dimension of individual, group, and organization. As a result of comparative analysis of theory of organizational knowledge creation theory, In knowledge management, building of knowledge-creative culture, transitional process of explicit knowledge and tacit knowledge, knowledge creation and knowledge operation are important. In the basis on these study results, we discussed how the organizational knowledge creation theory can be used to manage knowledge in the organization, and also proposed hypotheses based on some arguments against the universal acceptance of the theory.

This paper proposes an efficient market mechanism-based resource transaction model for grid computing. This model predicts the next resource demand of users and suggests reasonable resource price for both of customers and resource providers. This model increases resource transactions between customers and resource providers and reduces the average of transaction response times from resource providers. For prediction accuracy improvement of resource demands and suggestion of reasonable resource price, this model introduces a statistics-based prediction model and a price decision model of microeconomics. For performance evaluating, this paper measures resource demand prediction accuracy rate of users, response time of resource transaction, the number of resource transactions, and resource utilization. With 87.45% of reliable prediction accuracy, this model works on the less 72.39% of response time than existing resource transaction models in a grid computing environment. The number of transactions and the resource utilization increase up to 162.56% and up to 230%, respectively.

The conical-ended borehole technique and hemispherical-ended borehole technique are proposed, for the accurate stress measurement within a rock mass. Theory of stress tensor determination and in situ measurement system are presented with successful case examples, and the characteristics of stress distribution within rock masses are examined by the multiple times measurement in a single borehole. Subsequently, the problem in relation to the numerical approach for cavern designing is discussed on the basis of the dependency of the stress discontinuity on the geological discontinuities and so on.
