A large number of tasks being executed by individuals now are in a central requirement of the creative solutions consolidated with associates' multiple skills, knowledge bases and efforts who are capable of entertaining various viewpoints. Followed by such a variation, teams or groups were gradually settled in a major form of the enterprise's creative revelations. However, in spite of the consistent augmentation of team's application, researches of a group's ability that utilizes individual creative competence effectively are now in the excessively insufficient manner. Accordingly, this research is to verify mutual relationship between individual creativity and group creativity, and furthermore, to present integrative capability and knowledge sharing of the group as a distinctive variable to observe the mechanism of how the individual creativity becomes aggregated with the group creativity through a process. As a result, the relationship between the individual creativity and the group creativity was so significant that it showed that the integrative capability and knowledge sharing were mediated in the connection of the two variables. This research contributes to the comprehension of the relationship between individual and group creativity through the role of a group's integrative capability and knowledge sharing. In addition, further research direction with in-depth idea is presented to develop research on creativeness from the practical standpoint implicated in this research.

Purpose - This study aims to examine the determinants of income management of the public servant. Three independent variables are examined such as attitude towards money, financial capability and debt management while the dependent variable is financial wellbeing of public servants. Research design, data, and methodology - Quantitative research is applied in this study, and data are collected by using cross sectional approach. Survey questionnaires are obtained from 270 respondents, which represents 79% response rate. The multiple regressions are used to examine the influence of attitude towards money, financial capability and debt management towards financial wellbeing. Results - The result of the multiple regression indicated positive influences of attitude towards money and financial capability on financial wellbeing. However, debt management found no significant influence on financial wellbeing. Conclusions - Research findings show that people have different attitudes towards money and different trends of expenditure. It is also crucial to be highlighted that employees' attitude and financial capability have a greater influence on overall satisfaction with employees' financial wellbeing. Some would want to show off their luxury items they bought to close friends or relatives and some are very prudent in making expenditures even for necessity items.

The flight deck of an aircraft carrier is relatively vulnerable compared to its hull, as the damage of some subsystems on the flight deck may cause the carrier losing its operational capability. Therefore, this work aims to represent a simulative method for evaluating the resistance of the flight deck's operational capability in the condition that the aircraft carrier is together with its strike group and the enemy uses the anti-ship missiles with the cluster warheads to attack. In the simulations, the susceptibility of the carrier and the vulnerability of the aircraft guarantee resources are gained. Then, with the help of the closed queuing network, the residual sortie generation rate can be solved, which reflects the flight deck's residual operational capability. The results have proven that the flight deck is of strong resistance to these attacks while it is very sensitive to the loss of some key aircraft guarantee resources.

Purpose - Along with emerging international entrepreneurship, there is a need for exploring the influencing mechanism of dual network embeddedness of the host country on international entrepreneurial performance. Drawing on network embeddedness theory and organizational improvisational theory, the present study constructs a theoretical model regarding the logic relationships between the dual network embeddedness of the host country, organizational improvisational capability, and international entrepreneurial performance. Design/methodology - Using a questionnaire survey, our study conducted data in two ways. The final research sample comprised 129 international new ventures. To test the hypotheses, a three-step mediation test method was conducted. Findings - Our empirical results suggested that both host-country social network embeddedness and industrial network embeddedness significantly affected the international entrepreneurial performance. Organizational improvisational capability significantly affected the international entrepreneurial performance. Third, organizational improvisational capability partially played mediating role in the relationship between the dual network embeddedness of the host country and international entrepreneurial performance. Originality/value - This study mainly concentrates on the two important types of host-country networks, host-country social network embeddedness and industrial network embeddedness, that may help international new ventures access the strategic resources necessary to support performance. Thus, it extends the existing network embeddedness theory and improvisational theory to encompass international entrepreneurship.

본 연구에서는 해외에 진출한 중견기업을 대상으로 혁신성공요인과 혁신성과를 알아보고자 하였다. 보다 구체적으로는 경영자, 조직, 종업원 차원의 요인과 관련하여 리더십, 운영시스템, 변화주도행위를 혁신역량에의 영향 변수로 설정하였으며 혁신역량이 혁신성과에 미치는 영향을 실증 연구를 통해 파악해 보고자 하였다. 더불어 혁신역량에의 영향요인과 혁신성과에 미치는 영향이 본국과 해외진출국가 에서 어떠한 차이가 나는지를 알아보았다. 실증 분석 결과 혁신영향요인 모두 혁신역량에 긍정적 영향을 미치고 있었으며, 혁신역량은 혁신성과에 긍정적 영향을 미치고 있었다. 영향력의 정도에 있어서는 운영시스템, 리더십, 변화주도행위의 순으로 나타났다. 국가간 차이에 있어서는 중국의 경우 운영시스템, 리더십, 변화주도행위의 순이나 큰 차이는 없는 것으로 나타났다. 한국의 경우는 운영시스템과 리더십은 긍정적 영향을 미치나, 종업원의 개별적 변화주도행위는 혁신역량에 영향을 미치지 않는 것으로 나타났다. 본 연구 결과는 해외 진출 기업에게 있어서는 현지 특성에 맞는 혁신역량 강화 노력이 필요하다는 점과 한국의 경우 보다 고도화된 혁신역량 및 혁신성과의 창출을 위해서 종업원 개인의 변화주도행위를 이끌어 내도록 하는 추가적인 활동이 요구됨을 보여주고 있다.
