Informal networks between individuals are widely seen as important in East Asian business systems. However, while the performance implications of guanxi in China have been extensively studied, much less is known on how informal networks may influence business outcomes in other East Asian countries. We examine informal networks in inter-organizational research collaborations in South Korea by studying the role of pre-existing social ties and relational orientation in new product development (NPD) collaborations and university-industry research (UIR) collaborations. We conduct an interview-based, in-depth case analysis of five NPD collaborations and five UIR collaborations. Pre-existing social ties and relational orientation are prevalent in both types of research collaborations. However, they have different consequences for collaboration outcomes. Pre-existing social ties strongly vary in their types and strength, and negatively affect collaboration outcomes unless they result in the selection of competent and motivated partners. Relational orientation manifests itself in a task-related and social exchange between collaboration partners, which contributes to outcomes such as knowledge acquisition and business performance. Korean collaboration managers should rely only on pre-existing social ties that are well-aligned with task-related requirements when initiating and conducting research collaborations. However, the creation of strong relationships between collaboration team members of partnering organizations should be encouraged.

Game industry, one of cultural-content industry which is considered as a typical knowledge-based industry and creative industry, is not like the overseas expansion of traditional manufacture, and has different strategy and performance of export expansion through product or project-based strategy. Therefore, it should be approached by each content unit, and necessary to look at the factors that make their decision makings of foreign market entry vary. This study focuses on discovering creativity, absorptive capacity and strategic orientation(market orientation and innovation orientation) which affect the difference of distribution's decision making of entry into foreign market in game industry This paper examined 252 cases of online games in order to investigate creativity, absorptive capacity and strategic orientations for each foreign market and what entry type(among licensing, joint distribution, exclusive distribution) they chose according to the products developed in team level. This helps us analyze the factors affecting market orientation and innovation orientation in the perspectives of creativity and absorptive capacity in comprehensive way, and notice the phenomena which use different foreign distribution strategy though there are company incorporated abroad and their results. This study supplements the limit of the existing Resource-Based View, Resource-Dependent View, and traditional international business theories such as Transaction Cost Theory or OLI Paradigm(Eclectic Framework), and proves how company could reduce asymmetry of uncertainty and information in creative industry and whether they accomplish successful overseas expansion according to strategic orientations.

This study examines the effect of founders' strategic orientation and social capital on the performance of startups in Korean contexts. Founders' strategic orientation is proposed as the main factor to reduce the risk of failure and to increase the potential of future growth of the startup. Three main components of strategic orientation, entrepreneurial, market, technology, were simultaneously tested with a sample of Korean startups. Furthermore, founders' social capital, networks with supporting entities and the level of chemistry within founding members were also proposed to be important factors. We also tested possible mediating effects of social capital on the main impact of strategic orientation. With a sample of 79 startups founded less than 5 years in Seoul Metropolitan Areas, we found that technology orientation of founders only significantly increases the performance of startups, but both entrepreneurial and market orientation do not. Regarding social capital effect, the external networks of the founding members are effective as proposed, and also the high cohesiveness of founding members increases the startup performance. However, the mediating role of social capital is just partially confirmed. The implications of our findings, in both sense of firm's strategy and startup policy, are discussed. This study is expected to be a bridge connecting firms' strategy with startup policy-making in Korea.

The purpose of this study was to investigate what effect providing the hospice care team with hospice education programs had on the death orientation. The subjects of study were 28 volunteers. 14 nurses. 30 clergies who registered on hospice education programs from Aug. 6th. 1996 to May 20th. 1997. The data were analysed by descriptive analysis. ANOVA. Duncan test. paired t-test. The results of the study can be summarized as follows ; 1. The degrees of death orientation were 85.70 in volunteers group. 84.31 in nurses group. and 73.00 in clergies group. So. clergies group has more positive death orientation than others(F=6.33. p=. 000). The degree of death orientation showed significant differences between age groups(F=5.78. p =.002). and religiosity(t=3.92. p=.000). There were no significant differences between the degree of death orientation and the others general characteristics of subjects. 2. The mean of death orientation was 80.04 before hospice education programs. but was 75.56 after hospice education programs(t= 3.92. p= .000). In conclusion. the subjects who received the hospice education programs showed the positive change in the degree of the death orientation. Therefore. it has been judged that education programs has been prerequisite in positive death orientation for hospice care. Furthermore. all of the hospice care members those who complete the hospice education program. will be performed efficient hospice care intervention for dying patients and their families.

The purpose of this study is to examine antecedents and outcomes of trust toward supervisor in organization. The model is developed by reviewing previous research providing various perspectives. Antecedents consisted of three trustworthy behaviors - ability, benevolence, integrity - and three transformational leader behaviors - performance management, motivation, team-orientation -, and job satisfaction and organizational commitment is used outcome variables of trust. Data was collected from 206 employees in 6 organizations in broadcasting industry, using self-report questionnaire. Study finding is as following. First, trust in model was composed by 2 type - affect-based trust and cognition-based trust -, not divided in empirical analysis. Second, regression analysis for trust carry out independently, jointly with trustworthy behaviors and leadership behaviors. In antecedents of trust trustworthy behaviors, ability and benevolence has positive effects to trust, integrity has negative relationship with trust. It was high correlation between trustworthy behavior and leadership behavior. Especially, it has highly correlate(correlation efficient 0.69) between ability and team-orientation that influences trust strongly. Third, trust was not significant relationship with individual variables such as age, period with supervisor. Only, it found significant gap in variables and found out different relationship between variables among organizations distinctly. Fourth, job satisfaction and organizational commitment was positive influenced by trust and found out strong relationship between trust and organizational commitment.

In this study, polyimide(PI) nanofibers mats were prepared by electrospinning and three different fiber morphologies of random, uniaxial, and biaxial orientation were prepared by controlling the speed of drum-shaped collector and other parameters. The SEM studies reveal that the aforesaid morphologies were obtained on the nano-fibrous mats prepared. The ionic conductivity was measured using an in-plane type conductivity tester for the PI mats soaked in the mixture of 1M lithium trifluoro-methane-sulfonate and tetra-ethylene glycol dimethyl ether. The ionic conductivity was surprisingly higher for the biaxial PI mats. For the uniaxially-oriented mats, the ionic conductivity was found to be higher in the parallel direction compared to the perpendicular direction of the fiber orientation. A curious cyclic fluctuation was found in the ionic conductivity with time. The observed behavior was explained by considering the distance between fibers and transport speed of ions used in this study.

Many studies have been published on the relationship between project management styles and project performance. In recent researches, it is argued that project management styles should be different based on project characteristics and these project characteristics may have an effect on the relationship between project management styles and project performance. However, there are few empirical studies covering these issues. In this study, we examined the effect of project characteristics (i.e., degree of newness) on the relationship between project management styles (i.e., team autonomy, internal and external communication, individualism orientation) and project performance. The empirical results using 78 government sponsored R&D projects showed that team autonomy has a stronger positive effect on project performance as project newness becomes higher. In addition, as project newness becomes higher, internal communication showed a stronger positive effect on project performance, while external communication had a stronger negative effect.

Leaders should encourage successful organizational activities based on active participation by employees and create the best environment for working with a sense of mission and responsibility. This study aims to identify the relationship between empathy leadership and job engagement as a result variable of team cohesion in the hotel culinary department and conduct empirical studies on the role of empathy leadership and job engagement. Research design, data, and methodology: The data were collected from employees who work in culinary department at a five-star franchise hotel located in the Seoul metropolitan area. Because it is difficult to conduct a survey through face-to-face contact with employees due to the COVID-19 pandemic, the online survey was conducted from February 1 to February 28, 2020. A total of 330 questionnaires through online were distributed and 268 employees completed the survey, yielding a response rate of 81%. Of the 268 returned responses, 27 responses were not usable due to missing information. Thus, a total of 241 responses were used for analysis. Results: The study results are as follows. First, it has been shown that the empathy leadership of culinary department in hotel companies has a significant positive impact on the job engagement. Second, it has been shown that job engagement has a significant positive effect on members' team cohesiveness. Third, empathy leadership of hotel companies' culinary department has a significant positive impact on members' team cohesiveness. Fourth, job engagement has a significant positive (+) mediating effect in the relationship between empathy leadership and team cohesiveness in culinary department. Conclusion: This study supports the theory that an emotional and empathic leader's behavior or ability can change the effectiveness or atmosphere of a rapidly changing hotel culinary team organization by presenting a research model on the effect of empathic leadership on job engagement and team cohesiveness. And hotel chefs should be more aware of the importance of empathic leadership and make them a human resource of the organization through formal and informal communication with culinary employees.
