Data scientists are new knowledge workers representing the knowledge economy era. Knowledge workers perform unstandardized works that solve ambiguity-intensive problems. Therefore, self-leadership, which emphasizes self-motivated, autonomous judgment and execution, significantly influences their work-related outcomes. Even knowledge workers have high occupational commitment, they usually show low organizational commitment. Knowledge workers' intention to leave is also relatively high due to this reason. This study focused on data scientists' self-leadership, predicted that self-leadership would increase an organization's commitment and intention to leave. Based on the trait activation theory(TAT), the author also confirmed how perceived job autonomy enhances self-leadership influences. Results showed that data scientists' self-leadership significantly lowered intention to leave through organizational commitment and this mediating effect was moderated by perceived job autonomy. This study broadened the theoretical understanding the effects of knowledge workers' self-leadership and presented practical implications for managing data scientists.

We study empirically analyzed the final 216 copies of the responses from SME organization members in Seoul and Gyeonggi regions using statistical programs of SPSS24.0 and AMOS 24.0. In other words, the effect of job satisfaction on the organizational culture and job environment characteristics perceived by members of the organization, and the relationship between job satisfaction and job performance is shown as follows. First, the organizational culture of consensus, development, hierarchy, and rationality was statistically significant in job satisfaction. Therefore, the hypothetical one-man organizational culture was adopted by showing a positive (+) effect on job satisfaction. Second, job environment characteristics such as autonomy in job performance, compensation system, physical environment, and human environment had a positive effect on job satisfaction. That is, the job environment characteristics of hypothesis 2 were adopted as a positive (+) influence relationship on organizational satisfaction. Third, job satisfaction was expressed as a positive (+) influence relationship with job performance, so hypothesis 3 was adopted. As a result of this study, the higher the organizational member's perception of organizational culture and job environment characteristics is, the higher the job satisfaction is, and the improvement in job satisfaction is meaningful in that it provides theoretical and practical implications that indicate job performance.

Objectives : This research analyzed the general characteristics of care workers and verified the correlation among self-perceived health, job stress and customer orientation. Methods : We conducted a survey from May 1st, to May 31st, 2015 of 260 care workers who are affiliated with elderly care facilities or home care facilities in Busan, Korea. Results : The more the workers were stressed about their organizational culture, the more they recognized psychological difficulties. However, there was no correlation between organizational culture and their tendency to be oriented toward customers. It was verified that the recognized psychological health has a positive regulation effect between customer orientation and job stress such as job skill requirement(p<0.01), job autonomy(p<0.01), and organizational culture(p<0.01). Conclusions : Because both suppliers and recipients of care services are aging, it is necessary for elderly care facilities to make a greater effort to minimize the physical and psychological losses of recipients.

This study was designed to construct and test structural equation modeling on nurses' emotional labor including antecedents and consequences based on the model of Morris and Feldman (1997). A total of 247 nurses working at secondary and tertiary hospitals in three provinces responded the questionnaires. Emotional labor was measured by frequency of emotional labor, attentiveness of required display rules and emotional dissonance. Routineness of job, job autotomy and organizational support were measured as antecedents; and emotional exhaustion, job satisfaction and organizational commitment were included as the consequences of nurses' emotional labor. Data were analyzed by SPSS 21.0 and AMOS 21.0. The model fitness indices for the hypothetical model showed NFI=.94, CFI=.97, and RMSEA=.07. Job autonomy and perceived organizational support had significant effects on emotional labor. The emotional labor influenced positively emotional exhaustion and negatively job satisfaction and organizational commitment. Nurses' emotional labor mediates between job characteristics and nurses' psychologic results indicating more autonomy and support can reduce nurses' emotional labor and then increase their satisfaction and organizational commitment, and decrease emotional exhaustion.

Purpose: The purpose of this study is to clarify the role of decoupling between job characteristics, innovation behavior, and innovation resistance in order to seek ways for companies to survive and grow continuously through innovation activities in various uncertain situations. Research design, data and methodology: A total of 263 valid questionnaires were collected and used for analysis for employees working at the company. For the analysis, simple and multiple regression analysis, and 3-step mediated regression analysis were conducted using SPSS 24.0 and AMOS 24.0. Results: First, it was found that skill variety, task identity, autonomy, and feedback increase decoupling, and decoupling increases innovation resistance. In addition, it was confirmed that decoupling had a mediating effect between job characteristics and innovation resistance excluding task significance. Finally, it was found that task significance and feedback increase innovation behavior, and decoupling and task identity increase innovation resistance, but feedback can alleviate innovation resistance. Conclusions: As a result of the analysis, the fact that job characteristics excluding task importance have a positive effect on decoupling means that there are two sides of job characteristics perceived by employees. In other words, it means that the results of analysis on the jobs that the company assigns to its members may not be effective. In addition, decoupling, a phenomenon that seems to be accepting on the outside, but perceives that it is negative on the inside, means that there is a possibility to reject innovation. Therefore, prior to carrying out innovation activities, companies should give clear job specifications and meanings for the job and give them autonomy when assigning jobs to their members. In order to provide appropriate feedback, the company must design, operate, and provide feedback. It was found that there was a need to review the overall effectiveness. In addition, efforts such as strengthening corporate-level fairness, maintaining psychological contracts, and realizing authentic leadership should be preceded to reduce decoupling.

Purpose - The intent of this research is to discover the factors that enhance innovative work behaviors of group members in order to strengthen the competitiveness of small enterprises. In addition, we verify that employee job characteristic factors have an influence between antecedent variables and dependent variables in the work situations at small companies. Research design, data, and methodology - This study is focused on identifying the factors, such as self-efficacy, leader member exchange (LMX), and collective efficacy, which promote innovative work behaviors. A total of 305 valid questionnaires were collected. Results - The results of a path analysis showed that LMX did not have significant effects on task significance, and autonomy did not have significant effects on innovative work behavior. Conclusions - These findings of the study imply that even though leaders supported the groups in accordance with official procedures by placing group members within or outside certain groups, task identity perceived by group members was not impacted. In addition, autonomy given to those with relatively less capability might be a burden rather than a positive outcome.
