As information systems are implemented in business organizations, users and other stakeholders are known to resist changes incurred by information systems being implemented. For successful implementation, it is critical to manage changes overcoming resistance. Through literature review and expert panel, this study derives four underlying dimensions of resistance (anxiety, suspicion, imposition and self-centeredness) and five categories of change management activities (vision, leadership, communications, education and training, and organizational culture). A Survey was designed to measure the relationship between these dimensions and activities, and administered among information systems consultants. It is found that activities related to vision and leadership is underpinning other change management activities. Anxiety and imposition can be mitigated by education and training while suspicion is to be overcome by communications and self-centeredness by activities related to cultural changes. Implications are discussed and further researches are suggested.

In simple topology in network system, query should be delivered to all linked peers for query processing. This causes waste of transmission band width and throughput of each peer. To overcome this, as well as query processing strategy, efficient routing technique to deliver query to proper peer is needed. For efficient routing, clustering of peers in P2P networks is important. Clustering of P2P network bases on that combines peers that have similar characteristics in same cluster reduces quantity of message in network than assign peer for cluster randomly. In this paper, we propose clustering techniques for ontology based P2P query processing. Similarity measure point, cluster index structure, and query processing steps in ontology based P2P cluster environment are proposed.

The legacy methods for converting a business model to a feature model make it difficult to support an automatic transformation due to a dependence on a domain analyzers' intuitions, which hinders the feature oriented development for the integration of feature modeling in business modeling. This paper proposes a method for converting a BPMN business model into a feature model based on syntax. To allow the conversion between the heterogeneous models from BPMN to the FM(Feature Model), it defines the grouping mechanism based activities' syntax, and then makes translation rules and a method based on the element (represent business function) and structure (relationships and process among elements), which are common constructs of their models. This method was applied to an online shopping mall system as a case study. With this mechanism, it will help develop a mechanical or automated structure transformation from the BPMN model to the FM.

This study obtains design assessment indexes that should be considered in order to improvements of the public space was to analysis the importance in the public officials/academics and practitioners side. Obtained assessment topics in accordance with characteristic of public space through previous research to them and after a detailed selection indicators was so lead through the FGI. Derived surface was subjected to the significance analysis AHP through the survey expert. For this study, the importance of the public space are working professionals usability, publicness, environment, connectivity, identity, spatiality the order, public officials/academics usability, environment, connectivity, identity, spatiality, publicness the order. In addition, professionals working in the comprehensive analysis of the most important priority was to recognize safety, public officials/academics of the most important element appeared to have cleanliness. The results obtained in this study will be used as an index that can be used in planning and evaluation for consideration of the next improvement of public space.

Improving lecture quality is very necessary for the service quality of education in universities, enterprises and education institutes. The student lecture evaluation survey data is a good tool for measuring lecture quality and have been often analyzed by simple statistical methods. This study presents an intelligent lecture quality improvement method that can improve student's overall satisfaction and performance by analyzing student lecture evaluation survey data. The method uses SOFM (Self-Organizing Feature Map) neural network and C4.5 to find the patterns in student's satisfaction and performance more correctly and then decide what to change in the lecture for the improvement of student's satisfaction and performance. We apply the proposed method to an enterprise lecture in Korea. We can find that it can improve the quality of an enterprise lecture by changing total lecture time, lecture material and organization of lecture schedule to be necessary improvements.

In this study, we developed career guidance guidelines in order to support professors in guiding the career development of female students in engineering programs. Focus Group Interview (FGI) was conducted by a group of experts composed of 7 professors at the department of computer engineering in order to identify the current status and draw guidelines. It was found that the female students of engineering college were required to improve their efficacy, strengthen their major competency, improve their practical job competency, cultivate basic competency, and provide guidance on specific employment information. Then, we suggested the five elements of each grade and checklists focusing on five elements and proposed the forms so that they can be easily utilized in actual career guidance. At two expert meetings, the validity of the guidelines and the forms were verified and revised. Finally, we suggested a way to streamline the application of these guidelines.

The purpose of this study is to examine the relationship among workplace spirituality, creativity, and organization performance in the Korean context. In South Korea, workplace spirituality has recently received attention from scholars and practitioners. However, research on workplace spirituality is little known in the South Korean business context. Creativity is positively related to intrinsic motivation. The workplace spirituality can provide a corporate several advantages for their competitiveness in developing employees' creativity as well as resulting in more effective organizational performance. 514 cases was analyzed for this study. Three all factors (Inner life, meaningful work, & membership) of workplace spirituality as intrinsic motivation positively influenced employee creativity. employee creativity positively mediated the relationship between workplace spirituality and team productivity.

The importance and necessity of convergence research to solve complexity and diversity of research problems is more increasing. For successful convergence research, connectivity beyond the boundary and distance between disciplines is a key factor. To understand the current status and characteristics of connectivity among researchers, we investigated the interdisciplinary relationships among 487 researchers' disciplines in a university by using network anaylsis. The results showed that (1) connectivity between similar disciplines were higher than different disciplines, (2) the density and cohesion level of connectivity within the same campuses were higher, and (3) network centrality was concentrated in engineering and medicine. Based on these results, the necessity of overcoming boundaries and distances as obstacles to convergence research and the necessity of diversification of centrality were proposed. While previous studies mainly analyzed the research outcomes, this study is meaningful because it analyzed researchers' connectivity and collaborative structures in the actual convergence research procedures.

This study aims for investigating the consumers' reaction to the New Hanbok Style of K-pop idol groups. We collected YouTube videos and user comments that include 'Black Pink New Hanbok' as a keyword, applying social network analysis and sentiment analysis. First, the New Hanbok of Black Pink was designed as a mini-dress to make it easier to dance and turned out that it reinterpreted traditional elements modernly. Second, the issue about revealing costumes appeared as a keyword in domestic reactions, it did not appear in international reaction. Third, as a result of sentiment analysis, international audience viewed New Hanbok outfit more positively than domestic audience. This study is significant in that it suggests the direction to which New Hanbok should head to by investigating extensive consumers' reaction and finding out the positive and negative elements of New Hanbok.
