  • The main purpose of this study was to empirically investigate the effects of participation behavior and performance improvement on motivation factors of Korean university students which participated in LINC by utilizing Vroom's Expectancy Theory. Three motivation factors of valence, instrumentality, and expectancy were examined in this study. In addition, two different models (valence and force model) analyzed the causal relationships regarding participation behavior and performance improvement. 236 data were collected and findings of this study were as follows: First, comparative analysis between demographic characteristics including university, major, and residence had no significant differences in mean value. However, females had higher levels of recognition related to valence (attractiveness) relative to males. Second, valence and the force model were significant predictors of LINC participation behavior and performance improvement. Furthermore, the coefficient of determination and beta coefficient of the force model were higher compared with the valence model. Third, the level of mediation effects including direct, indirect, and total effect of the force model was higher than the valence model. LINC participation behavior had a partial mediating effect between the three motivation factors and performance improvement variable.

  • This study aims to investigate overall factors regarding participation process such as process to pro-environmental behavior, pro-environmental behavior, continuing factors and constraint factors of outdoor recreation participants, and to determine logical correlation between them in order to make a theory model. To this end, grounded theory approach is applied for interpretation. First, pro-environmental behavior of outdoor recreation participants was formed by sequential influence of causal conditions and situational context. Second, outdoor recreation participants who participated in pro-environmental behavior of central phenomenon experienced peculiar continuing factors and constraint factors but it was found they also experienced general continuing factors and constraint factors. Third, it was analyzed that resultant settlement of pro-environmental leisure activities was partially fed back to the participation continuing factors of mediating conditions and a club of interaction strategy. Result from this study will give a help to widely understand experience of participation in leisure and restraints on leisure of outdoor recreation participants, and to development of study through organic combination between subsequent researches.

  • Purpose: The purpose of this study was to understand an individuals' COVID-19 vaccine acceptance intention during the peak of the pandemic by utilizing the coping theory and technology threat avoidance theory (TTAT) as a framework. Specifically, we focused on understanding how inward and outward emotion-focused coping (EFC), such as psychological distancing and emotional support seeking, affect problem-focused behavior (PFC), which is vaccine acceptance. Furthermore, we investigate how the individuals' cognitive appraisal to- ward COVID-19, consisted of perceived threat and perceived avoidability act as an antecedent of EFC. Methods: A PLS-SEM analysis was conducted to find the causal relation between the variables. An online survey was conducted targeting vaccination recipients on April, 2021. Participants were asked about their perception toward the virus, their coping strategy, and vaccine acceptance intention. A total of 186 valid samples were collected and used for the analysis. Furthermore, to analyze the out-of-sample predictive power of the research model and ensure the generalizability of the results, a PLSpredict analysis was conducted. Results: The results of the PLS-SEM analysis show that perceived threat toward COVID-19 significantly affect an individuals' EFC strategy. Furthermore, both types of inward EFC (psychological distancing, wishful thinking) negatively affected vaccine acceptance intention. On the other hand, emotional support seeking, which is a type of outward EFC, positively affected vaccine acceptance. The result of the PLSpredict analysis confirms the generalizability of the PLS-SEM result. Conclusion: The results of our study could be utilized to decrease vaccine hesitancy and prevent global pandemics by accelerating and increasing vaccination. Our study provides several meaningful implications to researchers and practitioners regarding vaccine acceptance and threat coping behavior.

  • Despite the success of recent genome-wide association studies investigating longitudinal traits, a large fraction of overall heritability remains unexplained. This suggests that some of the missing heritability may be accounted for by gene-gene and gene-time/environment interactions. In this paper, we develop a Bayesian variable selection method for longitudinal genetic data based on mixed models. The method jointly models the main effects and interactions of all candidate genetic variants and non-genetic factors and has higher statistical power than previous approaches. To account for the within-subject dependence structure, we propose a grid-based approach that models only one fixed-dimensional covariance matrix, which is thus applicable to data where subjects have different numbers of time points. We provide the theoretical basis of our Bayesian method and then illustrate its performance using data from the 1000 Genome Project with various simulation settings. Several simulation studies show that our multivariate method increases the statistical power compared to the corresponding univariate method and can detect gene-time/ environment interactions well. We further evaluate our method with different numbers of individuals, variants, and causal variants, as well as different trait-heritability, and conclude that our method performs reasonably well with various simulation settings.

  • Purpose: This study is to investigate the causal relationship between franchise headquarters' franchise cost and franchise satisfaction and management performance, and to verify the structural relationship between franchise cost and corporate permanence. Research design, data and methodology: The data were collected from 200 medium-sized franchisees in Seoul and analyzed using confirmatory factor analysis (CFA) to test the validity of the measurement model and the structural equation model (SEM) to identify the impact of franchise costs on corporate performance with the Amos 28.0 program. Result: Franchise costs were found to have a negative effect on franchise satisfaction and corporate permanence. It was confirmed that franchise satisfaction had a significant positive effect on management performance and corporate permanence. Franchise costs had a sequential mediating effect on franchise satisfaction and management performance, which had a significant impact on corporate permanence. Conclusions: This study expanded the theoretical scope by applying the expectation confirmation theory to corporate transactions. In addition, the franchise headquarters proposes ways to create a culture of franchise business with trust by presenting appropriate franchise costs to improve management performance and corporate permanence through franchise satisfaction.

  • This study confirmed the relationship between variables developed by qualitative ground theory through quantitative research. The purpose of the study is to explain the effect of core sales tasks on sales services and the mediating effect of organizational member relationships on sales services. The data were collected through a survey of fashion brand salespeople in Gwangju from September to October 2020 with data from 235 responses analyzed using SPSS 27.0 and AMOS 26.0. The validity of the research model verified the confirmatory factor analysis and the research hypothesis was verified through path analysis and multi-mediated analysis of the structural model. The research results were as follows. First, sales management did not directly affect sales services, and customer management affected sales services. Second, a meaningful causal relationship was shown to exist between organizational member relationships and sales management, but organizational member relationships and customer management did not have a significant relationship. Third, the total and individual indirect effects of headquarters relations, colleague relations, and customer management were all statistically significant.

  • There are two competing models explaining the causal relationship of depression and self-esteem, and they are cognitive vulnerability model and the scar model. Cognitive vulnerability model explains that low self-esteem poses as a risk factor for development of depressive symptoms/depression while the scar model asserts that the experiences of depression scars the cognitive function of individuals, resulting in negative self-perception. This study was set out to test two models on Korean adults, and to identify factors that are associated with depression and self-esteem relationship. The first four waves (wave 1~4) of the Korea Welfare Panel Study (KOWEPS) were used for analyses, and latent growth curve modeling was employed to examine the relationship. The findings show that the relationship was reciprocal, one affecting the growth trajectory of another over a four year period. Furthermore, education, poverty status, health status, and satisfaction with social relationships were found to be significantly associated with both depression and self-esteem trajectories. Implications for practice and theory are provided.

  • The purpose of this study is to understand the experiences and perspectives of the self-reliance program participants through a longitudinal qualitative study from 2006 to 2012. Based on Grounded theory approach, it examines how participants managed their lives up to now status. Through open-coding process, 181 meanings were identified. Paradigm model shows that the goal of the self-reliance program can be viewed as causal condition. However, contextual factors such as poverty experiences and child-support affected the self-reliance program participants to adapt and stay in the program rather than actively participate in the market. The finding shows that the meaning of self-reliance are differently understood by policy makers and self-reliance program participants.

  • This is a convergence study to present strategies for performance enhancement by verifying the causal relationship between the influencing factor on the performance of the healthcare-associated infection control guidelines in hospital nurses. Participants were 388 nurses recruited from 16 different tertiary and general hospitals in Korea. Data collection was conducted using self-report questionnaires and analyzed using SPSS 21.0 and AMOS 21.0 programs. The overall fitness was ${\chi}^2=99.64$ (df=14, p<.01), GFI=.94, RMSEA=.10, NFI=.84, CFI=.90. The explanatory power of predictive variables on intention were 23.8%, and those on behavior were 17.7%. As a result of this study, it was found that TPB is an appropriate theory to explain the performance of healthcare-associated infection control guidelines, and repeated studies including multi-level modeling of career experience and organizational influences on behavior with strong social characteristics are needed.

  • The purpose of this study is to analyze the diffusion period and productivity of smartwork in an organization. Firms are increasingly interested in smartwork for non contact work and working from home because of the corona 19. The smartwork is a new technology that changes face-to-face work in an organization. It helps the work of individuals and organizations regardless of time and place. The theoretical background describes the complexity, system thinking, diffusion theory, smart work, organizational resistance, and productivity. This study analyzes the diffusion period and productivity of smart work through business simulation techniques. A simulation study progresses four stages. There are problem definition, hypothesis establishment and causal loop diagram, model construction and verification, and policy evaluation. The simulation models contain an individual's resistance variables organizational investment and leadership variables related to the operation of smartwork. The organizational investment variables include organizational culture, legal system, implement systems and technology investment. The individual resistance variables include cognitive, attitude, structure and technological resistance. The leadership includes leadership interest variables and performance linkage variables. The simulation executed the changes of a people number adopting smart work and the organizational productivity monthly. As a result of the simulation, many organization members have accepted the smart work innovation after 20 months. The organizational productivity through smart work showed very high value after 16 months. In scenario analysis, the individuals' awareness and attitude resistance showed very important variables to productivity and a personal change of smart work adoption. Meanwhile, The organizational investment showed that the high driving-force increased not productivity and the low driving-force showed decreased low productivity. Also, leadership variables showed a powerful driver for changing smart work productivity. The implication of the study has suggested extending complexity, diffusion theory and organization resistance theory based on simulation methods.
