This study was conducted to clarify the mediating effects of self-efficacy and organizational commitment on the level of depression associated with emotional labor and occupational stress of call center representatives. The survey subjects were 486 representatives working in four call centers in D city. Data collection was conducted using structured, self-addressed questionnaires from January 5th to 25th, 2017. The results showed that the depression level of the representatives was significantly higher in the emotional labor and occupational stress groups and higher in the low self-efficacy and organizational commitment groups. The correlations between variables revealed a positive correlation between depression, emotional labor, and occupational stress, but a negative correlation between self-efficacy and organizational commitment. Path model analysis revealed that emotional labor and occupational stress had positive effects on depression, while self-efficacy and organizational commitment was negatively influenced. In addition, self-efficacy and organizational commitment had a mediating effect on emotional labor and depression, while organizational commitment had a mediating effect on occupational stress and depression. Therefore, to reduce the depression level of call center representatives, it is necessary to reduce the emotional labor and occupational stress factors, as well as to have a mental health mediation plan to increase self-efficacy and organizational commitment.

Purpose - Previous studies related to emotional labor of salespeople have mainly focused on identifying the antecedents of emotional exhaustion and turnover intention and exploring the mitigating effects salespeople's motivation on emotional exhaustion and turnover intention. They also demonstrates that there are different roles for moderating in social support, which means mental/physical support related to the job in supervisors, colleagues and organizations. The purpose of this paper is to investigate how service employees' surface acting affect turnover intention through emotional exhaustion. Another important objective of this paper is to investigate whether perceived social support moderates 1) the relationship between surface acting and emotional exhaustion 2) the relationship between emotional exhaustion and turnover intention. Research design, data, and methodology - To test the hypotheses, we collected the data from Korean insurance company sales employees. A total of 235 responses were received, from which 220 usable responses were obtained after list-wise deletion. Working with a sample of 220 responses, structural equation modeling was employed to empirically test research hypotheses(

The relationship between surface acting and emotion exhaustion,

The relationship between emotion exhaustion and turnover intention,

The moderating effect of perceived social support(PSS) on the relationship between surface acting and emotion exhaustion, and

The moderating effect of perceived social support(PSS) on the relationship between emotion exhaustion and turnover intention. SPSS 22.0 and AMOS software were used in these data analysis. Results - The service employees' surface acting was positively related to the emotional exhaustion; in turn, the service employees' feelings on emotional exhaustion are positively related to turnover intention. In addition, Perceived Social Support significantly moderated the relationship between surface acting and emotional exhaustion. However, perceived social support has a non-significant moderating effect on the path from emotional exhaustion to turnover intention. On the basis of these results, the following conclusion can be drawn. First, distribution service companies will be needed the administrative efforts to offer counseling programs and space to provide their members with enough rest in experiencing psychological pain due to the salespeople's surface acting. Also, it is necessary for distribution service companies to identify and share the examples of successfully solving emotional exhaustion caused by salespeople's surface acting.

An influx of the population to the city has soared due to industrialization. As times go by, cities become densely populated so Korean government started to construct a number of buildings including apartment housings. Because they have become functionally, structurally, esthetically deteriorated over the past two decades. some improvements are needed. There are mainly two ways to improve old buildings: remodeling and reconstruction. Between the two, the first one is more popular as it is less time-consuming and more eco-friendly. Demolition work comes first for both of them and it should not give negative effects since it is regarded as a CP(Critical path) in the overall process. For this reason, a thorough construction management must be done. The reality, however, demolition is managed by the construction manager's experiences and decisions. If the key factor of demolition which is the planning of manpower and machine equipment, is determined by unscientific and subjective judgments, its period and risk also will increase. In particular, eco-friendly demolition can be more risky because it's been rarely conducted. Therefore, scientific and objective ways of demolition management are needed. In this context, this paper aims at analyzing productivity in each process of demolition focusing on manpower and machinery equipment which are the main parts of demolition assuming that the demands of eco-friendly remodeling demolition projects will be increasing. At the same time, by estimating working period through the output, this paper would be helpful to set up the plans for overall project in earlier stage.

A multipurpose operating system was developed to adjust both spray times and ventilation method without a configuration of the moving path and the type of the greenhouse. The multipurpose working system proved to be a reliable system for testing the growth quality of the fruit vegetables in the greenhouse. The results are as follows. The first leaf, diameter of a stem, leaf area, and average stem diameter in the Cucumber seedling growth were repressed by high-speed ventilation, but was not repressed by spray times. The first leaf in the Tomato seedling growth was repressed as ventilation velocity was high, but the average stem diameter was not repressed. While the Tomato was given water three times a day, the diameter of a stem and the leaf area were increased as ventilation speed became higher. However, those were different other factors. The Tomato leaf area was larger when given water twice a day than that in hand spray, but showed no difference with ventilation speed. The first leaf, the diameter of a stem and the leaf area of a Red pepper were lower in automatic spraying with ventilation than those in hand spray.

This study was conducted to establish and verify a theoretical model that explains the factors and pathways influencing the psychological well-being of nurses. The subjects of this study were nurses working in four general hospitals with over 200 beds in B city and G province. The results of verifying the path coefficient of the nurses' job rotation stress showed that job rotation stress had a significant effect on challenge stress, hindrance stress, and nurses' psychological well-being, while hindrance stress had a negative effect on nurses' psychological well-being. Nurses' job rotation stress had direct effects on challenge stress, hindrance stress, and psychological well-being. Hindrance stress had a direct effect on psychological well-being. In addition, nurses' job rotation stress had an indirect effect on psychological well-being through hindrance stress. Nurses who experienced job rotation showed challenge and hindrance stress. Since hindrance stress interferes with the psychological well-being of nurses, it is necessary to manage stress and make efforts in the nursing organization. Therefore, nursing organizations should establish a positive organizational environment and develop systematic strategies so that job rotation can be a challenging stress factor for nurses.

The purpose of this study is to examine the influence of the leisure constraint of a private security guard on his/her task stress and life satisfaction. The subjects of this study were chosen among the private security guards working in Seoul based private security firms in 2009, and by going through judgement sampling, 300 cases were applied in the final analysis. Collected data went through factor analysis, reliability analysis, regression analysis, and path analysis by using SPSSWIN 17.0. In reference with the reliability of the questionnaire, Cronbach's $\alpha$ was over .600. The conclusion of this study is as following. Firstly, the leisure constraint of a private security guard affects his/her task stress. In other words, when peripheral and individual constraint increase, task stress is intensified, while task stress winds down when interpersonal constraint decreases. Secondly, the leisure constraint of a private security guard affects life satisfaction. That is, when individual constraint goes down, life satisfaction is improved. Thirdly, the task stress of a private security guard affects life satisfaction. when compensation and career development increase, life satisfaction rises. On the other hand when task characteristic is weakened, life satisfaction gets lower. Fourthly, the leisure constraint of a private security guard has a causal influence on task stress and life satisfaction. Accordingly, it becomes apparent that the task stress is a significant variable which intermediates the relation between leisure constraint and life satisfaction.

Purpose - Environmental issues, climatic changes, and greenhouse gases are problems to be solved at a global level. With an increased emphasis on the environmental and social responsibility of the management of companies, the manner in which companies approach quality-oriented culture and their individual sustainability management are being discussed as truly important issues to help them secure their competitiveness and growth strategies. This study proposes strategic directions to help manufacturers not only in expanding their competitive quality-oriented company culture but also in strengthening their sustainability management abilities. This study conducts a literature review and empirical research to examine how significantly the variables of a quality-oriented company culture, customer-centered management, and process-centered and supply chain management-centered cooperation affect sustainability management performance in relation to economic profitability, environmental integrity, and social responsibility. Research design, data, and methodology - To verify research models and hypotheses, the study examined 170 companies using a questionnaire survey conducted over six weeks, and involved the performance of data analysis on 146 samples. Questionnaire responses were calibrated based on a Likert scale. The study used the Smart PLS 2.0 program designed for PLS (partial least squares), an analysis instrument of SEM (structural equation modeling). The study then verified empirical research hypotheses working on reliability analysis, validity analysis, factorial analysis, and path analysis. Results - Among the nine hypotheses, four are accepted and the rest are rejected. A quality-oriented company culture focusing on customer-centered management significantly influenced the maintainability management performance of environmental integrity and social responsibility, while economic profitability was dismissed. A process-focused quality-oriented company culture was significantly concerned with economic profitability but not with environmental integrity or social responsibility. A supply-chain cooperative company culture had a significant effect on economic profitability but not on environmental integrity or social responsibility. Conclusion - This study proposes strategic directions to help manufacturers expand their competitive quality-oriented company culture as well as strengthen abilities with sustainability management. It conducts a literature review and empirical research to examine how significantly the variables of quality-oriented company culture, customer-centered management, and process-centered and supply chain management-centered cooperation affect sustainability management performance in relation to economic profitability, environmental integrity, and social responsibility. There are two main conclusions. First, companies should consider the need for social responsibility management and environmental transparent management-focused maintainability management as avenues to create new markets and business, thereby helping the companies secure a reputation for having a customer and process-centered quality-oriented company culture by creating shared values between supply chains and enabling win-win situations through cooperation. Second, we are marching towards a creative win-win era from a society of conflicts and ruptures. Companies should understand that social responsibility management and supply chain management (SCM)-focused cooperation are the foundations of sustainable development, as they try to improve their culture while pursuing both win-win relationships with interested parties and equity in various conflictive relations.

This study attempted to examine the relationship between pygmalion leadership and the organizational commitment among hospital employees, and the mediating effect of the leader-member exchange (LMX) on their relationship. For this purpose, we designed structured self-response survey questionnaires, and collected data from 349 employees working at 9 hospitals and ambulatory clinics in Busan area. Frequency analysis, correlation analysis, factor analysis, and reliability analysis were performed using SPSS ver.18.0 program, and the path analysis was performed using AMOS ver.18.0 program. Major findings are as follows. First, some factors of pygmalion leadership were found to directly influence the quality of LMX, while some had both direct and indirect influences on organizational commitment. Second, the quality of LMX was found to partly mediate the relationship between pygmalion leadership and the organizational commitment in hospital organizations. This is the first in kind which was conducted in the hospital setting.
