This study attempted to test not only the influence of transformational leadership(TFL) on employees' unethical pro-organizational behavior(UPB), but also the mediating effect of organizational identification(OID) between TFL and employees' UPB. This study employed two research methods: literature review and empirical testing of the developed hypotheses. Data were collected through online questionnaire instruments from 229 employees working at companies in Korea. To test the hypotheses, structural equation modeling was employed. The model is shown as adequately fitting to the data. The results showed that there was not a positive and statistically significant relationship between TFL and employees' UPB, and OID played as a mediator in the relationship between TFL and employees' UPB. These findings provide a meaningful implication that the positive impact of TFL is linked to employees' UPB through OID.

This is an experimental study which is designed to identify the joint relationship between communication density and centrality as independent factors to team performance, discovering how they would jointly affect work team performance. Specially different from existing studies, separating team performance into team efficiency and team effectiveness, we identified differential influences to the two independent factors. Findings suggest a competing relationship between communication density and centrality. A framework was proposed to help managers understand the joint effect of density and centrality on performance. Work team has high communication density and low centrality is "Innovating", which is likely to have a great extent of ideas, knowledge and information sharing, and reach high effectiveness. Team with high centrality and low density is characterized as "centralized". Such communication structure may reduce diversity of perspectives and accelerate team decision making. When both density and centrality are low, the team is "Autonomous". To increase external validity, other factors such as leadership, organizational climate influencing on team performance should be reflected in the future research.

The market size of online games has been rapidly growing as well as the behaviors of online gaming users have been changed. Online games are different from the traditional video games, because they permit players to interact each other during playing games. Today online gaming is a part of everyday life and social interaction has an impact on online gaming behaviors. Social interaction does not only have a positive impact on online game behaviors, but it also has a negative impact on them such as excessive online game usage. Previous research has a limitation to consider social interaction as a comprehensive concept. In order to fill the gap, we explore the factors of social interaction influencing on excessive online game usage. After reviewing previous literature, this study chooses three factors of social interaction such as escaping loneliness, expanding online social bridging capital, and reinforcing offline social bonding capital. The findings show that all of three factors of social interaction positively affect the excessive online game usage.

This study investigates SNS usage behaviors of SNS users with a change of SNS use environment and an increase of users. This study compares the difference of use motivation, preferred type, and main use SNS according to socio-demographic variable of SNS users using cross tabulation analysis and also conducts a comparative analysis of main use SNS of each SNS user using correspondence analysis. The results show main use motivation of SNS is relationship seek, most preferred type is closed type, and main use SNS is Kakaostory. Next, we find that there are differences on use motivation, preferred type, and main use SNS, depending on the socio-demographic characteristics of SNS users. The result of correspondence analysis shows how users are using SNS services and what structure their competitive relations of SNS services are made. In the conclusion, the study presents summary of the findings, implications, and tasks for further studies.

ICT-convergence cluster is considered as critical policy means because it can create higher value-added products and services in the era of creative economy. Previous research has focused on comprehensive ICT-convergence cluster strategy based on Porter's diamond model. This paper adopted AIDA(Attention, Interest, Desire, Action) model and investigated a specific domain of government supporting policies related to non-R&D support. For two weeks, we gathered and analyzed 181 data from companies located in Chungbuk province. The results showed that support for technology, commercialization, and participation conditions positively leads to companies' interest in ICT-convergence cluster, which, in turn, makes positive impact on their intention to participate in it. It is significant that this paper verified AIDA model in the Government-to-Business(G2B) context. Future research will need to adapt AIDA model to national projects.

Internal and external environment changes surrounding our society are pressing our government to solve a lot of difficult problems. These problems are more likely to be solved by a number of ministries and agencies, rather than a single ministry or agency. Thus collaboration is a necessary strategy to increase government's problem-solving skills. This study examines determinants of successful collaboration by analysing cases of local governments that solved uneasy problems covering many ministries after persistent efforts which have been controversial issues in our society. First, theoretical approach for collaboration and its matrix is examined. Second, interviews of government officers are analyzed to study collaboration cases. Finally, Strategic points of view are discussed to promote collaboration within government sectors. The results show that common goal sharing, incentives and supporting systems play important roles in inducing collaboration.

The concentration phenomenon in physical space has taken place along with the proliferation of ICT in South Korea, especially the concentration in Gangnam_Gu district of plastic surgery clinics. In this study, we examine longitudinally whether the proliferation of ICT is related with the concentration in the physical space: focused plastic surgery clinics in Gangnam_Gu district. To do this, we extend the previous study(Cho and Choi, 2012). We examine the homogeneity between websites of plastic surgery clinics in Gangnam_Gu and those besides Gangnam_Gu plastic surgery's website. Multiple Discriminant Analysis (MDA) technique is mainly used for this analysis. The 401 sample websites in 5 years from 2006 to 2011 are mainly investigated. As a result, plastic surgery websites in Gangnam_Gu are not homogeneous than those of elsewhere with significance during 5 years consistently. Therefore, we can conclude that the expansion of ICT has an association with the spatial concentration of plastic surgery in Gangnam_Gu.

Architectural history traces the changes in architecture through various traditions, regions, overarching stylistic trends, and dates. This study identified terminologies related to the proximity and frequency in the architectural history areas by text mining and association analysis. This study explored terminologies by investigating articles published in the "Journal of Architectural History", a sole journal for the architectural history studies. First, key terminologies that appeared frequently were extracted from paper that had titles, keywords, and abstracts. Then, we analyzed some typical and specific key terminologies that appear frequently and partially depending on the research areas. Finally, association analysis was used to find the frequent patterns in the key terminologies. This research can be used as fundamental data for understanding issues and trends in areas on the architectural history.

In recent years, the importance of collaboration has been emphasized in the public sector as well as private companies. In a study for private enterprises, individual enterprises stressed the innovation through collaboration with other organization such as enterprise, university, and other agencies. Other companies and agencies have the technology they need, so that they share skill or knowledge, and they do to create more new developments. This implies a collaborative system can be a win-win collaboration with all partners. It also requires collaboration in the public sector. Because they have many problems that can not be solved at the level of individual institutions. However, public institutions lie ecologically unfavorable in a collaborative environment than the private sector. The organizational structure is hierarchical. In addition, relationships between collaboration partners not recognize horizontally. Of course, communication is not smooth. This study examines successful collaboration case in private sector and we want to draw implications for public organizations. Finally, we discussed ways to promote collaboration in the public sector.

Although numerous theoretical and empirical studies on the capital structure have been performed, the studies on the capital structure of the high potential enterprises have not been worked. This paper performed empirical analyses for the first time to find out the determinants of capital structure of the high potential enterprises of Korea using the financial data of the manufacturing high potential enterprises listed on the Korea Exchange and KOSDAQ during 2010~2016. The results of regression analyses with debt ratio as dependent variable and profitability, firm size, asset tangibility and non-debt tax shield as independent variables show that the coefficients were relatively significant. The variables of the profitability and the tangibility were found to have positive relationship with the debt ratio. The non-debt tax shield were found to have in general positive relation with the leverage.
