This study incorporates the structural relationships between leadership styles (LS), affect climate (AC), and organizational performance (OP) in Korean export manufacturing companies with three or more overseas subsidiaries. A theoretical model is suggested with the following empirical results. First, the positive effect of engaging leadership (EL) on organizational citizenship behavior (OCB), as well as of engaging leadership, involving leadership (IL), and goal-oriented leadership (GL) on team performance (TP), proved to be significant. Second, both engaging leadership and goal-oriented leadership have significant positive effects on optimism, while involving leadership has significant negative effects on pessimism. Third, only optimism has a positive (+) effect on OCB and TP. The mediating effects were proved to be significant in two paths: one in EL->optimism->OCB and the other in EL->optimism->TP. Finally, in responding to rapid changes in the external environment of exporting companies, the engaging leadership is a key source of organizational performance by forming a favorable affect climate. Therefore, top management should recognize the role of team leaders and strengthen their leadership training. In addition, it was confirmed that leaders with emotional intelligence that can respond to the affects of members play a more important role in forming an optimistic climate in Korea export manufacturing enterprises with foreign subsidiaries.

Nowadays, omnichannel is a new kind of e-commerce channel. Many retailers invest in this channel to maximize customers' benefits as well as increase competitive advantage and business performance. To operate this channel effectively, the role of IT competence is very important. With the flexibility and integration of IT competence in omnichannel, retailers can optimize service quality and bring customer benefits that are outstanding in comparison with the traditional channel. Because of this significance, this research was carried out to evaluate the effects of IT competence on the business performance of retailers in Vietnam's omnichannel environment through the mediating role of customer value creation and competitive advantage. A quantitative research method is used through a survey with 200 managers working in retail companies operating omnichannel in Vietnam. After collecting data, PLS-SEM software is used to analyze the relationship among these above factors in omnichannel. The results prove that there are positive effects of IT competence on other elements in the research model. All direct and indirect effects are valuable when bootstrapping. Based on the results, some managerial implications are given to managers of retail companies using omnichannel to improve customer values and increase competitive advantage and business performance in the Vietnam context.

For advanced civil engineering structures a service life of hundred up to hundred fifty and even two hundred years is sometimes required. The prediction of the performance of concrete structures over such a long period requires accurate and reliable predictive models. Most of the presently used, mostly experience based models don't have the quality and reliability that is required for reliable long-term predictions. The models designers are searching for should be based on an accurate description of the relevant degradation mechanisms. The starting point of such models is a realistic description of the microstructure of the concrete. In this presentation the need and the role of fundamental microstructural models for predicting the performance of concrete structures will be presented. An example will be given of a microstructural model with a proven potential for long-term predictions. Besides this also the role of models in general, i.e. in the whole design and execution process of concrete structures, will be dealt with. Finally recent trends in concrete research will be presented, like the research on self-healing cement-bases systems.

The paper investigates investor sentiment's role in boosting Japanese companies to enhance their environmental, social, and corporate governance (ESG) performance. Using ESG scores of 367 firms between 2005 and 2019 from the ASSET4 database, we find that negative sentiment in the previous year, both firm and market level, can be a stimulation for the company's commitments to its ESG activities next year. Notably, the moderating effect of the business sector and economic cycle on the sentiment-ESG inference are detected in our study differentiating between corporate and market sentiment, which have never been reported before. In detail, we discover that the impact of firm-specific sentiment is less pronounced for high-sensitive ESG firms. On the other hand, the driving force of market sentiment on corporate social behaviors weakens when economic recessions happen. Our results are robust after controlling for potential endogeneity issues and using alternative proxies for market sentiment.

Objectives: The purpose of this study was to evaluate the efficiency of patient and doctor role-play on participatory clinical clerkship by surveying student's satisfaction and assessing the improvement of skill and consultation ability after conducting a role-play in a Korean dermatology department. Methods: In 2013, 79 seniors participated in the clinical clerkship of the dermatology department at the college of Korean medicine. Two students were randomly selected and paired up. After a brief instruction, one student played the role of doctor and the other took the role of patient. After finishing the $1^{st}$ role-play, they swapped roles and conducted a $2^{nd}$ role-play, using another clinical case. When the two role-plays were completed, the students filled in a questionnaire about their satisfaction with the role-play as clinical clerkship. Also, we compared the scores of the $1^{st}$ role-play with those of the $2^{nd}$ role-play measured by a medical resident to assess improvements of students' skill and interview ability. Results: It appears that students' satisfaction with the role-play was quite high, considering that the overall mean score of the questionnaire was 4.30. According to the result of a t-test on 15 assessment questions, the $2^{nd}$ role-play had a higher mean score than the $1^{st}$ role-play in 12 questions, though this difference was not statistically significant. Conclusions: These results demonstrate that role-play is helpful to improve students' satisfaction and clinical performance ability in clinical clerkship. Further research and continuous development are necessary for better clinical clerkship.

Have elderly parents parted with parental role after the children were grown up? If they still have, what kinds and degrees of parental responsibilities endured? Do they actively perform the role? Do they satisfy to engage in parenting? The main purpose of present study explored these questions conceming rural old-aged families using data of 143 elderly parents aged 60 years and above. The results indicate that elderly parents perceived parenting adult children to be very important, regarding themselves as househeads to teach family members how to integrate together. The results also demonstrate that elderly parents performed parental role actively in teaching family rituals and providing emotional support. The elderly parents also report that they were fairly satisfied with involvement in adult children's lives. Our findings suggest that further in-depth research is required in eliciting the role parameters of elderly parents based on our social and cultural changes. In addition, it is encouraged to examine the adult children's expectation of their elderly parents for renegotiating and restructuring parent-child relationships when both are adults.

This paper aims to propose a conceptual model that empirically examines the relationship of psychological empowerment & role satisfaction and their dimensions with motivation in an Indian context. 176 executives/managers from many public sector organizations in India were approached. Cronbach alpha, correlation and regression analyses were applied to check the research hypotheses. Only meaning was found to be important predictor of motivation. Interestingly, achievement and extension were also observed to be the determinants of motivation. This paper would help researchers and practitioners to work on these variables in some other sectors also. Improvement in the psychological empowerment and role satisfaction will enhance the motivation among Indian business executives/managers which will improve the overall performance of the organization. It is an innovative attempt to utilize psychological empowerment and role satisfaction independently to improve motivation in an Indian framework.

Purpose - Inducing consumers' behavioral intent to use an outlet shopping center is a critical issue for managers since it can be used as a guide for developing marketing strategies. Low prices could lead to a growth in retail purchases, but there might also be a positive relationship between prices and customer perceptions of product quality. The extent to which consumers use price as a predictor of quality may differ according to the availability of important alternative cues such as brand, store name, and identity salience triggered by the store. Consumers can obtain non-economic benefits from marketing exchanges that go beyond basic economic achievement. We argue that identity salience can play a crucial mediating role when consumers, acting as exchange partners, seek to obtain social benefits. This study shows that identity salience could mediate the relationship between identity salience-inducing factors such as multi-finality, prestige and role performance, and consumers' behavioral intent to use an outlet shopping center. Research design, data and methodology - The survey was conducted on college students enrolled in marketing classes. A total of 200 questionnaires were distributed, of which only 194 were returned. After five incomplete questionnaires were excluded, a final sample of 189 was used for empirical analysis. Using a covariance structural analysis in Amos17, we confirmed the fit of the research model and estimated its parameters by using the maximum likelihood method. Results - The results of the hypotheses testing are as follows. First, both identity salience and economic benefits have positive effects on the behavioral intent to use an outlet shopping center. Second, role performance, prestige, and multi-finality have positive effects on identity salience. Finally, the additive analysis of the direct effects of identity salience-inducing factors shows that the role performance, prestige, and multi-finality factors have no direct effects on the behavioral intent to use an outlet shopping center, suggesting that identity salience plays a positive mediating role. Conclusions - This study informs marketers that not only price but shoppers' identity salience directly affects their intent to visit an outlet shopping center. To strengthen shoppers' identity salience, marketers should find ways to help shoppers fulfill their multiple social roles, realize their multiple goals, and achieve prestige. In other words, outlet shopping centers must improve their personal service environment in order to enhance their employees' service quality and assist the execution of multi-finality by minimizing the perceived costs (e.g., travel time, effort) associated with shopping trips, thus making it easier for consumers to combine visits to multiple stores in outlet shopping centers and buy the items required for their consumption goals. Outlet shopping centers must also offer assortments with both breadth and depth in order to help consumers play the social roles their social networks have given them.

To improve the competitiveness of the hospital provides high quality medical services in a hospital coordinator role is emphasized. This study on customer orientation of the role ambiguity in order to identify the impact of degree of customer orientation were analyzed for demographic differences. Dependent variable, customer orientation affects role ambiguity as independent variables, and regression analysis were set. And the control variables are set to support situational factors, customer orientation on the role ambiguity and hierarchical regression analysis was performed. Obtained through empirical results are as follows: First, according to the demographic characteristics of the hospital coordinator customer orientation, the difference between gender and medical subjects are not shown. Age, education, work experience, job title, and the hospital on the pattern of customer orientation has shown a difference. Second, according to the hospital coordinator role ambiguity about its impact on customer orientation analysis can be a role implementation, job implementation, opinion communication in achieving customer orientation was negatively affected. Third, role ambiguity, and customer orientation factors for the moderating effects of organizational support for the role of customer orientation can role implementation, job implementation, opinion communication was a statistically significant. Fourth, the role ambiguity factors and customer orientation for the administrative support for the moderating effect of customer orientation and role implementation is significant, but job implementation, opinion communication were statistically significant. Fifth, the role ambiguity factors and customer support for customer orientation and customer orientation for the moderating effects of role performance and the opinion communication was not statistically significant. However, job implementation was statistically significant. The limitations of this study are as follows: First, role ambiguity, situational factors and support due to limitations of the variable factors that may affect the customer orientation of a number of factors were excluded. So many exogenous variables in the measurement process can affect. Second, the variables measured as problems of self-assessment by the variable measuring the respondent's bias may occur. Third, This study is difficult to generalize. In other words, several areas of the province conducted by the empirical results of the survey as a limit on the overall generalization can follow.

This study aims to analyze the effect of transformational leadership (TL), procedural justice (PJ), and training (T) on employee performance (EP) mediated by self-efficacy (SE). The object of this research is Rumah Sakit Umum Daerah (RSUD) M.Th. Djaman, a hospital in Sanggau Regency, while the subjects are the institution's staff. Data collection search uses purposive sampling with a total of 120 samples. Data are obtained through questionnaires distributed directly to respondents using the Google Form application. Data analysis techniques used in this study include standard error of mean (SEM) with AMOS software version 24.00. Methods use to test validity and reliability of data include Confirmatory Factor Analysis (CFA), Construct Reliability (CR) and VE. The results of the analysis show that only training has a significant effect on self-efficacy, and self-efficacy has a significant effect on employee performance. Also, self-efficacy is proven to mediate the role of training on employee performance; the other hypotheses are not significant. Training is the most prominent positive factor affecting self-efficacy and self-efficacy has a significant effect on employee performance at RSUD M.Th. Djaman. The results of this study can be used as a reference by management in determining what policy priorities should take precedence.
