Purpose: The purpose of this study was to develop and test a structural model on work-related musculoskeletal disorders of women workers. Method: Data were collected from 237 women workers from industries such as electronics, food production and garment production, and analyzed by LISREL 8.54. Result: The fitness indices of the model are GFI=.87, NNFI=.91, PNFI= .74. Eight out of the ten paths were proved to be statistically significant: work environment$\rightarrow$social support, work environment$\rightarrow$health behavior, work environment$\rightarrow$-WMSDs, domestic work$\rightarrow$health behavior, social support$\rightarrow$health behavior, social support$\rightarrow$job satisfaction, health behavior$\rightarrow$job satisfaction, and job satisfaction$\rightarrow$WMSDs. Work environment. social support, health behavior and job satisfaction significantly influenced WRMDs. WRMDs were accounted for 35% by the predictor variables. Conclusion: In conclusion, this study identifies that work environment, social support, health behavior and job satisfaction are important factors affecting WMSDs. Therefore, in order to prevent WRMDs, it is most important to improve both physical work environment for female workers such as appropriate work station and tools fit for them and psychological environment such as less job demand and more decision latitude(worker control).

Purpose: This study was done to investigate the factors affecting organizational commitment and turnover intention of hospital nurses. Empirical analysis on the mediating effect of the person-environment fit of organizational commitment and turnover intention and factors affecting this relationship were also examined. Methods: Participants were nurses working in 4 university hospitals in Seoul or Busan. Data were collected between July 27 and Aug. 10, 2012 and for the final analysis, 393 data sets were used. The fitness of models were tested using AMOS 19.0. Results: The fitness of the modified model showed high compatibility with the empirical data. In the modified model, organizational climate, professional self-concepts and person-organization fit were found to have significant effects on hospital nurses' organizational commitment. Professional self-concepts, personality, person-organization fit and person-job fit significantly affected hospital nurses' turnover intention. There was the mediating effect of person-organization fit between organizational commitment and turnover intention and factors affecting the relationship. But person-job fit was not found to have a mediating effect. Organizational commitment accounted for 49.8% and turnover intention for 39.9% of covariance in these factors. Conclusion: Nursing strategy for enhancing professional self-concepts and person-organizational fit should be planned by nursing managers.

As the importance of intellectual assets has been brought into relief, this study aims at positively verifying where the intellectual workers' overall level of their knowledge conversion preference and their job character has reached, and how much the knowledge conversion preference, the job character and the fitness of both factors affects the job effectiveness respectively. For this purpose 3 types of research hypotheses were set up and the result of the verification of the hypotheses is summarized as follows: First, the verification of the relation between the knowledge conversion preference and the job effectiveness revealed that the workers who have the higher synthetic ability in knowledge conversion preference show the higher job satisfaction and job product. Secondly, the verification of the relation between the MPS representing the job character by measured index and the job satisfaction revealed that the absolute value of relative coefficient between the 4 factors excluding the public welfare factor and the MPS is 4, interpreted as medium correlation. Thirdly, the analysis on the degree of relation between the job product measured by the quality of job result and the input effort and the MPS showed that the absolute value of person relative coefficient is 5, interpreted not only as medium correlation but also very meaningful. Accordingly, the main purpose of this study was to give a guideline which can be utilized as an indicator for educating, training and placing the workers. As results, the main effect that the variable of knowledge conversion preference and job character chosen as the independent variable influences on the dependent variable of job satisfaction and job product is very meaningful except the public welfare factor.

The purpose of this study was to understand the influence of employees' commitment (affective, normative, continuous) in the food & beverage departments of deluxe hotels upon job satisfaction and analyze the moderating effects of the leader-member exchange on the relationship between organizational commitment and job satisfaction. Based on a total of 403 food & beverage employees, this study reviewed the reliability and fitness of the research model and verified two hypotheses. The hypothesized relationships in the model were tested simultaneously by using SEM. The proposed model provided an adequate fit to the data, ${\chi}^2=635.160$ (p< .001), df=112, GFI= .845, NFI= .851, CFI= .874. SEM showed that organizational commitment (affective: ${\beta}=428$; normative: ${\beta}= .293$; continuous: ${\beta}= .342$) showed a positive significant influence on job satisfaction. However, the findings demonstrate that the leader-member exchange did not moderate the relationship between organizational commitment and job satisfaction. Limitations and future research directions are also discussed.

Purpose: This study was done to elicit basic data for effective human resource management by identifying the relationships among job embeddedness, emotional intelligence, social support, and the turnover intention of Nurses. Methods: Research design was to build a hypothetical causal model between variables and to verify its fitness. The sample for this study was 283 nurses with careers of more than 6 months in one hospital of more than 800 beds located in Seoul. They agreed in writing and this study was approved by the Institutional Review Board. Data were analyzed using SPSS 18.0 and AMOS 18.0 program. Results: Differences in general characteristics for the variables were significant for age, marital status, education, work experience, job title, income, and department. Job embeddedness, emotional intelligence and social support were significantly correlated to turnover intention. Job embeddedness to emotional intelligence and social support showed positive effects and a negative effect to turnover intention. Emotional intelligence to turnover intention showed a positive effect, but social support was not significant. Conclusion: Organizations should provide ways to minimize voluntary turnover of a competent workforce and demonstrate their competency. Also it should develop training and management programs to effectively utilize emotional intelligence.

Evolutionary algorithm is recognized as a promising approach to solving multi-objective combinatorial optimization problems. When no preference information of decision makers is given, multi-objective optimization problems have been commonly used to search for diverse and good Pareto optimal solution. In this paper we propose a new multi-objective evolutionary algorithm based on competitive coevolutionary algorithm, and demonstrate the applicability of the algorithm. The proposed algorithm is designed to promote both population diversity and rapidity of convergence. To achieve this, the strategies of fitness evaluation and the operation of the Pareto set are developed. The algorithm is applied to job shop scheduling problems (JSPs). The JSPs have two objectives: minimizing makespan and minimizing earliness or tardiness. The proposed algorithm is compared with existing evolutionary algorithms in terms of solution quality and diversity. The experimental results reveal the effectiveness of our approach.
