본 연구는 집합적 리더십(collective leadership)의 유효성을 검증하는데 그 목적이 있다. 구체적으로 집합적 리더십이 창의적 행동에 미치는 직접효과와 집합적 리더십과 창의적 행동간 조직기반 자긍심의 간접효과를 검증하고, 이러한 간접효과의 메커니즘이 심리적 안전감에 의해 조절되는 조건부 간접효과를 규명하고자 한다. 본 연구는 동일방법편의(common method bias) 문제점을 최소화하기 위해 직급과 함께 직무상황에서의 정서성(affectivity)을 통제변수로 사용하였다. 회수된 설문지 319부 중 부적절한 자료(univariate outliers) 10부를 제외한 309부가 분석에 사용되었다. 연구결과, 집합적 리더십은 구성원들의 창의적 행동에 정(+)의 영향을 미쳤고, 조직기반 자긍심은 집합적 리더십과 창의적 행동과의 관계에서 부분매개 역할을 하였다. 또한, 심리적 안전감의 조건부 간접효과는 '매우 낮음', '낮음', '중간'의 세 단계를 제외한 '높음', '매우 높음'의 두 단계에서 유의한 것으로 나타났다. 본 연구결과가 함의하는 바는, 조직의 리더들이 집합적 리더십을 통해 구성원의 조직기반 자긍심과 창의적 행동을 촉진하는데 있어 심리적 안전감이 높아야 그 효과성이 커진다는 것이다.

Purpose - This study aims to classify and extend the consumer value of movie theaters into various values such as functional value, emotional value, social value, epistemic value, and conditional value based on the theory of consumption value by Sheth, Newman and Gross (1991). It also aims to verify the path structure of consumption value→customer satisfaction→behavior intention of movie theaters to confirm its generalization. Research design, data, and methodology - This study was conducted by collecting data on Kimpo university students from various areas in Incheon, Northern Seoul, Ilsan, Kyonggi Province, and Kimpo City. The survey was conducted by distributing 280 survey papers from Oct. 5 to 15, 2013 and collecting 238 of them. The final analysis used 208 questionnaires, after excluding 30 invalid responses. The statistical analysis of this study used the SPSS 19.0 statistics package. Results - The results of the survey are as follows: First, consumption values of movie theaters are classified into the following five groups: functional value, emotional value, social value, epistemic value, and conditional value. This study verified that consumption values play a role as a previous variable of customer satisfaction. Second, functional value, emotional value, and epistemic value have positive effects on customer satisfaction. On the other hand, social value and conditional value do not affect customer satisfaction. Finally, customer satisfaction has a positive impact on behavior intention. Theater users have an intention to re-use or recommend the movie theater they used when they are satisfied with a movie theater's physical environment and services. Conclusions - This study can provide academic and practical implications as follows based on the results mentioned above. First, academic implications can be found in that consumption values of movie theater users are classified into five values based on the theory of consumption value by Sheth et al. (1991). In the previous study, the service quality of a movie theater was studied based on the service quality of service encounters and a physical environment→customer satisfaction→behavior intention path structure. However, this study was verified by a consumption value→customer satisfaction→behavior intention path structure to classify consumption value, but not service quality or perceived value of quality, to confirm this generalization. Second, practical implications can be found in that the relative impact of consumption value of movie theaters on consumer satisfaction showed that functional value was followed by epistemic value and emotional value. In the previous study on movie theaters, previous variables of customer satisfaction were separated only by functional service quality including service encounters and physical environment; in some other studies, quality of service encounter had a direct effect on customer satisfaction. Accordingly, a marketing manager of a movie theater should develop various differentiated services by reflecting not only functional value such as service encounters and physical environment but also epistemic value and emotional value.

Purpose - Previous studies tried to find antecedents of innovative behavior. However, research on knowledge hiding behavior, psychological mechanism, and perception of organizational justice has been relatively limited. In this sense, this study has investigated the impact of organizational justice on employees' innovative behavior and explored the factors that affect the above relationship. Especially, this study tested the direct effect of organizational justice on innovative behavior. This study also examines the mediating roles of knowledge hiding behavior in this causal relationship. Moreover, the process of organizational justice to innovative behavior is assumed to be influenced by leadership style. Therefore, we examined the moderating effect of authentic leadership on the relationship between organizational justice and knowledge hiding behavior. Design/methodology/approach - For the empirical test, we collected data via a questionnaire survey of a sample of 252 employees from Korean firms. We conducted a hierarchical regression analysis to test hypotheses. Results - The results of the empirical analysis revealed that organizational justice was positively related to innovative behavior and negatively related to knowledge hiding behavior. The results also showed that knowledge hiding behavior negatively mediated the relationship between organizational justice and innovative behavior. In addition, we found the moderating role of authentic leadership. More importantly, we found that the conditional indirect effect of organizational justice on innovative behavior via knowledge hiding behavior was depending on authentic leadership. Uncovering the relationship between organizational justice and innovative behavior through the mediating role of knowledge hiding behavior and the moderated mediating role of authentic leadership has useful theoretical and practical implications. We also suggest directions for future research by providing several limitations.

Purpose - The purpose of this study is to explore the impacts of Korean executives' trust on a firm's corporate social responsibility (CSR) activities and corporate financial performance (CFP), which depends on their individual social responsibility (ISR). Design/methodology/approach - A survey was conducted, and 273 Korean executives were recruited. I used SPSS version 25.0, AMOS version 26.0, SmartPLS version 3.2., and PROCESS Macro 3.4. to analyze the moderated mediation model. And, the Structural Equation Modelling (SEM) was employed to confirm the proposed relationships in the model. Findings - The results show that Korean executives' trust is positively related to CSR. I also found that Korean executives' trust is positively related to CFP. Moreover, I found that there is a mediating effect of a firm's CSR activities on the trust-CFP relationship. However, I didn't find conditional indirect and direct effects on the relationships among the proposed constructs. The findings overall suggest that Korean executives' trust is such an important mechanism that will affect firm-level CSR and CFP. Research implications or Originality - Although prior studies reveal that executives' trust in their subordinates positively influences cooperation, creativity, and innovation among subordinates in a team, it is still unclear whether executives' trust in their employees or strangers impacts firm-level CSR and CFP. Moreover, not many studies examined the mediating effect of CSR on executives' trust and CFP especially in the Korean context. Therefore, this study intends to fill the knowledge gap by focusing on South Korea. This study also contributes to extant CSR and trust literature, and practically contributes to executives, policy makers, and practitioners in South Korea.

Background: Pancreatic cancer is the sixth leading cause of cancer death with an increasing trend in China. Dietary intake is believed to play an important role in pancreatic cancer carcinogenesis. The aim of this paper was to evaluate associations between some dietary factors and risk of pancreatic cancer in a multi-centre case-control study conducted in China. Materials and Methods: Cases (n=323) were ascertained from four provincial cancer hospitals. Controls (n=323) were randomly selected from the family members of patients without pancreatic cancer in the same hospitals, 1:1 matched to cases by gender, age and study center. Data were collected with a questionnaire by personal interview. Odds ratios (OR) and 95% confidence intervals (95%CI) were estimated using conditional logistic regression. Results: Tea intake (OR =0.49; 95%CI: 0.30-0.80) was associated with a half reduction in risk of pancreatic cancer. Reduced vegetable consumption (P trend: 0.04) was significant related to pancreatic cancer. Although no significant association was found for meat and fruit, ORs were all above or below the reference group. A protective effect was found for fruit (OR=1.73 for consumption of 1-2 times/week vs more than 3 times/week; 95%CI: 1.05-2.86). A high intake of meat was associated to a higher risk of pancreatic cancer (OR=0.59 for consumption of 1-2 times/week vs. more than 3 times/week; 95%CI: 0.35-0.97). Conclusions: The present study supports fruit consumption to reduce pancreatic cancer risk and indicates that high consumption of meat is related to an elevated risk. Direct inverse relations with tea and vegetable intake were also confirmed.

Background: Several potential risk factors have been identified for diffuse large B-cell lymphoma (DLBCL); however, epidemiological studies investigating the association between these risk factors and DLBCL have yielded inconsistent results. Objectives: To investigate potential medical, lifestyle, and environmental risk factors of DLBCL in Shanghai, China through a hospital-based case-control study. Method: One-hundred-and-forty-seven newly diagnosed DLBCL patients and 294 sex- and age-matched controls were recruited from 11 hospitals in Shanghai between 2003 and 2007. A standardized structured questionnaire was used to obtain patient data on demographics, medical history, family history, lifestyle, and environmental exposures. Conditional logistic regression models were used to estimate odds ratios (ORs), with 95% confidence intervals (CIs), for risk associated with each data category. Results: History of tuberculosis (TB) infection and "living on a farm" were positively associated with DLBCL (TB: OR=3.05, 95% CI: 1.19-7.80; farm: OR=1.82, 95% CI: 1.21-2.73). In contrast, taking traditional Chinese medicine was negatively associated with DLBCL (OR=0.36, 95% CI: 0.14-0.89). No significant correlation with DLBCL risk was found for any of the other potential risk factors (p>0.05), including but not limited to hair dyes, alcohol drinking, smoking, and home/workplace renovation within one year. Conclusions: Consistent with results from previous studies in other DLBCL case populations, traditional Chinese medicine appeared to have a direct or indirect protective effect against DLBCL. However, this study also identified a possible predisposition for DLBCL in TB sufferers and farmers.
