This study explored how university entrepreneurial education service quality affects education satisfaction, entrepreneurial capability, and entrepreneurial intention. Although the various university entrepreneurial educations have been provided, current state of education support for entrepreneurial achievement is quite insufficient. In order to analyze factors for the entrepreneurial achievement enhancement, this study examines how university entrepreneurial education service quality affects education satisfaction, entrepreneurial capability, and entrepreneurial intention, as follows. First, in order to measure the entrepreneurial education service quality on the basis of theoretical background of the service quality, we set twenty one (21) questions for five (5) factors as follows: materiality, reliability, reactivity, certainty, consensuality. And then, impact of the entrepreneurial education service quality on education satisfaction and entrepreneurial capability was evaluated based on the survey results. Second, on the basis of previous studies of customer satisfaction, we gave the definition of education satisfaction for students in entrepreneurial education, and analyzed the causation that affects some elements of entrepreneurial capability (i.e. fulfillment capability, capacity of creativity, conceptualization capability, and social competence) by the aforementioned definition. Third, we analyzed the causation that affects entrepreneurial intention by education satisfaction and entrepreneurial capability. As a result, unlike the previous studies, there are only four (4) factors were confirmed for the entrepreneurial education service quality because the materiality and the reliability were founded as single element under the analysis. And it was identified that the entrepreneurial education service quality which is comprised of four (4) factors affects the education satisfaction and the entrepreneurial capability. In addition, as a result of the analysis under defining four (4) factors of entrepreneurial capability, the fulfillment capability and the capacity of creativity were founded as single element, and it was confirmed there is only three (3) factors, including the conceptualization capability and the social competence. With this result, it was confirmed that the entrepreneurial education service quality is influenced by the education satisfaction. Therefore, although the entrepreneurial intention is influenced by the entrepreneurial capability, it is not directly affected by the education satisfaction. These results showed that the education satisfaction affects indirectly to the entrepreneurial intention through the entrepreneurial capability that affected by the education satisfaction.

In this paper, we study the relationships between organization characteristics and desired software quality attributes of enterprise systems. We collected data from three client organizations in three different domains (auto manufacturer, insurance services firm, and government agency) that adopted enterprise software of the same software vendor. Our analysis discovers that capability is a more important attribute to the manufacturing and insurance firms than the government agency. Usability is ranked the highest among other attributes for the government agency and reliability for the manufacturing firm. The relationships identified in this study will help enterprise systems vendors predict their customer needs and, ultimately, increase effectiveness and efficiency in their software development processes. Such findings will be specially useful when software vendors develop enterprise software for a venture firm by enabling them to meet the customer needs customized by the organization haracteristics while staying within the incubating firm's limited budget.

As technology has developed and cost for data processing has reduced, big data market has grown bigger. Developed countries such as the United States have constantly invested in big data industry and achieved some remarkable results like improving advertisement effects and getting patents for customer service. Every company aims to achieve long-term survival and profit maximization, but it needs to establish a good strategy, considering current industrial conditions so that it can accomplish its goal in big data industry. However, since domestic big data industry is at its initial stage, local companies lack systematic method to establish competitive strategy. Therefore, this research aims to help local companies diagnose their big data capabilities through a reference model and big data capability assessment system. Big data reference model consists of five maturity levels such as Ad hoc, Repeatable, Defined, Managed and Optimizing and five key dimensions such as Organization, Resources, Infrastructure, People, and Analytics. Big data assessment system is planned based on the reference model's key factors. In the Organization area, there are 4 key diagnosis factors, big data leadership, big data strategy, analytical culture and data governance. In Resource area, there are 3 factors, data management, data integrity and data security/privacy. In Infrastructure area, there are 2 factors, big data platform and data management technology. In People area, there are 3 factors, training, big data skills and business-IT alignment. In Analytics area, there are 2 factors, data analysis and data visualization. These reference model and assessment system would be a useful guideline for local companies.

This paper analyzes the relationship between organizational development culture, intra-organizational trust, and communication and their influence on corporate competitiveness. The research model is composed that development culture has a positive effect on trust and communication, and that trust and communication have a positive effect on corporate competitiveness. The data for the analysis were integrated at the company level (510 companies) and used the data of 9,053 employees collected in the 1st survey of the Human Capital Company Panel(HCCP II) of the Korea Research Institute for Vocational Education and Training(KRIVET). For corporate competitiveness, responses to 10 factors for internal process capability and customer service capability were used. The structural equation model was employed to analyze the research model. As a result of the analysis, development culture had a positive effect on organizational trust and communication. And trust and communication were found to have a positively effect on corporate competitiveness. In the indirect effect analysis through bootstrapping, the development culture did not show indirect effects through trust and communication, so only direct effects between development culture, trust and communication, and corporate competitiveness could be confirmed.

Distribution system is one of large and complicated sytem, consisted of a great number of components. Therefore efficient operation based on precise analysis and computation methods is indispensable accommodating growing loads. This paper describes an optimal operation problem to relieve overload flow in radial distribution systems by using modified block model. The problem is formulated as a network problem of synthesizing the optimal spanning tree in a graph, branch and bound method is used for the optimization. Especially modified block model proposed in this paper is validated more practical than conventional model. These methods can be applied to two types of distribution system problems such as, 1) planning problem to check the capability of relieving overload at normal rating, 2) emergency operation problem to determine switching scheme for minimizing customer loads affected by a fault. Examples of application to these problems are discussed.
