This study aimed to examine the effect of management by objectives(MBO) and job commitment on the nursing performance of operating room(OR) nurses. The study was conducted on 226 OR nurses from tertiary healthcare institutions in Seoul. Multiple regression analysis was performed to determine the effect of OR nurses on nursing performance. In results, the factors that affect the nursing performance of OR nurses included the concreteness of goals, job commitment, and measurability of objectives in that order, and these variables explained 25.9% of the nursing performance. Therefore, in order to improve the performance of the nursing work, it is necessary to make efforts to create a work environment where nursing can be carried out due to the nature of the nursing operation. In addition, it is essential to develop a strategy to further the influence of the concreteness and measurability of goals among other attributes, thereby enhancing the job performance of OR nurses.

The global economic growth rate has been slowed due to changes in the economic and social environment related to the recent trends in the construction market and construction industry, prolonged inflation, intense tensions among countries, and increased interest rates. Since the workers in the construction industry, due to the nature of the industry, move to another site after the completion of an awarded project rather than staying for a long time while performing work at one workplace, various issues are brought out such as poor working environment resulting from unfairness in construction contracts, aging of workers, their anxiety, and job instability. The previous studies on the turnover intention of construction industry workers mainly dealt with external aspects such as leadership, job embeddedness, and organizational citizenship behavior, while the psychological impact was overlooked. The purpose of this study was to develop a measure to reduce or alleviate turnover intention of construction industry workers by verifying empirically the relationship among psychological capital, organizational commitment, and turnover intention among them. For the purpose, whether psychological capital influences organizational commitment and turnover intention, the impact of organizational commitment on turnover intention, and whether organizational commitment has a mediating effect in the relationship between psychological capital and turnover intention, among 310 construction industry workers in the metropolitan area. The results are as follows: First, hope and self-efficacy were found to have a negative (-) effect on turnover intention, while resilience and optimism from psychological capital did not have a significant effect. Second, hope, resilience, and optimism from psychological capital were found to have a positive (+) effect on organizational commitment, while self-efficacy from psychological capital had no significant effect. Third, organizational commitment was found to have a significant mediating effect on the relationship between hope from psychological capital and turnover intention. The results of this study showed that, in construction industry workers, psychological capital affects turnover intention through the mediating effect of organizational commitment. While previous studies mainly considered external influences on the turnover intention of construction industry workers, this study has academic implications in that it sought to strengthen organizational commitment and alleviate turnover intention by approaching psychological aspects. As a practical implication, it was found that higher self-efficacy and hope for work in the organization, from psychological capital, in the construction industry workers were found to lower turnover intention through job performance in a psychologically stable state. It is considered, therefore, that various systems, including job autonomy and flexible work, should be established to improve self-efficacy and hope.

Purpose: The purpose of this study was to test the empowerment structural model based on Kanter's work empowerment theory. Method: A predictive, nonexperimental design was used in a sample of 279 nurses from 3 university affiliated hospitals. Data were collected with self-administered questionnaires and analyzed using mean, standard deviation, pearson correlation coefficient and path analysis. Results: The results showed that the overall fitness of the hypothethical model to the data was good(chi-square=.7751, df=4, p=.942, GFI=.999, AGFI=.996, RMSEA=.000). Both formal power and informal power directly influenced on nurses' perceived empowerment level and empowerment directly influenced on nurses' organizational commitment and indirectly influenced on nurses' intent to stay. Conclusion: The results imply that hospital and nurse managers should provide the empowering working condition for nurses to be stayed in hospitals.

The strategy that using data collection from Netflix uses for its services is different from traditional human interaction and the communication, and it is represented by the systematic algorithm that rooted from intelligent information system based on the human interaction and communication. These characteristics allowed the study to reflect the influence of 'Asset specificity' which affects the continuous consumption of the media services of Netflix users through economic psychological analysis based on transactional cost economics. The result from the survey on actual Netflix users, three types of specificity (Space specificity, time specificity, relational specificity) reduced perceived searching cost whereas perceived instrumentality has increased, eventually reinforces the commitment to the service. This implies that the service characteristics of Netflix, trying to communicate with the individuals based on intelligent information system are distinct from the existing platform services and it gives the significance of work very effective for user's continuous consumption of the media services.
