The purpose of this study is to empirically analyze the mediating effect of job stress and Job engagement in job satisfaction between WFC(Work-Family Conflict) and quality of LMX(eader-member exchange) relationship of married female workers based on JD-R(Job Demands-Resources) model. A total of 945 people were targeted using the 7th panel data from the Korean Longitudinal Survey of Women and a structural equation model was used to verify the causal relationship and mediating effect of each variable using spss 23.0 and AMOS 21.0. As a result of the study, it was confirmed that WFC did not directly affect job satisfaction, and it was found that job satisfaction was negatively affected through job stress related to WFC. It was found that the quality of the LMX relationship had a positive effect on job satisfaction and reduced job stress, thus positively affecting job satisfaction. Job engagement was found to mediate the relationship between LMX and job satisfaction. This study is meaningful in that the search for multidimensional psychological and contextual factors that lead to job performance and job demands of married female workers are conducted.

This paper attempted to verify that Investigative Enterprising(IE) axis in the Holland hexagonal model can measure the internal and external job value. This study analyzed internal and external job values of 19 subjects who participated in the 150 Job cards classification test. The results of this study are as follows: First, the study group with Holland hexagonal model centered on the Investigative Enterprising type(IE) axis and artistic type(A) and social type(S) showed internal job value and supported the hypothesis. Second, the hypothesis that the group with the hexagonal model centered on the Investigative Enterprising(IE) axis and the bias toward the realistic type(R) and the conventional type(C) would pursue external job value was rejected. This is due to the Korean cultural context that pursues psycho-cultural value in Confucian culture. There is also a Holland hexagonal model that is not exactly distributed to the left of the Investigative Enterprising(IE) axis. Third, the group of amphibolic job value based on the Investigative Enterprising(IE) axis, and the Holland hexagonal model is expressed in artisic type(A), social type(S), realistic type(R), and conventional type(C) supported some hypotheses. This paper is the first to suggest that the Investigative Enterprising(IE) axis of the Holland hexagonal model can be used to measure job value, and the Holland hexagonal model can predict job value as well as career choice. This paper is intended to expand the foundation of the Holland theories, and to provide meaningful contribution to the basis for vocational studies.

Purpose: This study examined the associations of job stress and burnout with the quality of life (QOL) among 119 emergency medical technicians (EMTs). Methods: Using a descriptive correlational design, 260 EMTs working in D City or S City completed the questionnaires. Hierarchical multiple regression analysis was conducted to determine the predictors of QOL among 119 EMTs. Results: Overall, there was relatively low job stress among 119 EMTs. There were significant differences in job stress and burnout by general characteristics, especially regarding those of gender, service career, job rank, and self-reported health. In a hierarchical multiple regression, general characteristics explained 29% of QOL (Model I, F=16.369, p<.001). The explanatory power for QOL increased to 49% upon adding job stress (Model II, F=18.737, p<.001), and 59% upon adding burnout (Model III, F=22.621, p<.001). In the last model, self-reported health (${\beta}=.316$, p<.001), job demand (${\beta}=-.130$, p=.009), job insecurity (${\beta}=-.136$, p=.010), lack of reward (${\beta}=-.189$, p=.001), emotional exhaustion (${\beta}=-.196$, p=.004) and lack of personal accomplishment (${\beta}=-.334$, p<.001) were significant predictors of QOL among 119 EMTs. Conclusion: Based on the results, it is necessary to assess and manage job stress and burnout systematically among EMTs, and to develop health improvement programs for better QOL.

Job seekers are making various efforts to find a good company and companies attempt to recruit good people. Job search activities through self-introduction essay are nowadays one of the most active processes. Companies spend time and cost to reviewing all of the numerous self-introduction essays of job seekers. Job seekers are also worried about the possibility of acceptance of their self-introduction essays by companies. This research builds a classification model and conducted an experiments to classify self-introduction essays into pass or fail using deep learning and decision tree techniques. Real world data were classified using stratified sampling to alleviate the data imbalance problem between passed self-introduction essays and failed essays. Documents were embedded using Doc2Vec method developed from existing Word2Vec, and they were classified using logistic regression analysis. The decision tree model was chosen as a benchmark model, and K-fold cross-validation was conducted for the performance evaluation. As a result of several experiments, the area under curve (AUC) value of PV-DM results better than that of other models of Doc2Vec, i.e., PV-DBOW and Concatenate. Furthmore PV-DM classifies passed essays as well as failed essays, while PV_DBOW can not classify passed essays even though it classifies well failed essays. In addition, the classification performance of the logistic regression model embedded using the PV-DM model is better than the decision tree-based classification model. The implication of the experimental results is that company can reduce the cost of recruiting good d job seekers. In addition, our suggested model can help job candidates for pre-evaluating their self-introduction essays.

Each year research institutions such as the Korea Employment Information Service(KEIS), a government institution established for the advancement of employment support services, and Job Korea, a popular Korean job website, announce first job waiting times after college graduation. This provides useful information understand and resolve youth unemployment problems. However, previous reports deal with the time as a completely observed one and are not appropriate. This paper proposes a new study on first job waiting times after college graduation set to 4 months prior to graduation. In Korea, most college students hunt for jobs before college graduation in addition, the full-fledged job markets also open before graduation. In this case the exact waiting time of college graduates can be right-censored. We apply a Cox proportional hazards model to evaluate the associations between first job waiting times and risk factors. A real example is based on the 2008 Graduates Occupational Mobility Survey(GOMS).

The purpose of this study was to investigate the impact of organizational learning culture on job satisfaction and organizational commitment. Two streams of scholarly work have provided the theoretical foundations for this study. The first stream comes from the literature on learning organization. The second stream of the theoretical foundation comes from an extensive literature on attitude-intention-behavior relationships. In addition, this study was tested three alternative models. Alternative model 1 employed job satisfaction as the mediating commitments variable between learning culture and organizational commitment. Alternative model 2 used organizational commitment as the mediating variable between learning culture and job satisfaction. Finally, alternative model 3 specified a direct impact of learning culture on both job satisfaction and organizational commitment, and reciprocal linkages between these two variables. The results of this study support the hypothesized relations among an organization's learning culture, job satisfaction, and organizational commitment. The findings of this study are various congruent with a widely accepted hypothesis that job satisfaction serves as an appraisal function in evaluating various work environments and determining emotional responses such as organizational commitment. Organizational learning culture is one of the important factors that organizations cannot overlook. Therefore, the findings of this study provide a new direction for researchers seeking to explain the complex relations among these central organizational variables.

Background: Urban bus drivers work under conditions that are among the most demanding, stressful, and unhealthy with higher rates of mortality and morbidity as well as absenteeism and turnover. Methods: Drawing on the job demand-resource model, this study investigates the impacts of job characteristics on emotional exhaustion and the effects of emotional exhaustion on job outcomes (including job satisfaction, life satisfaction, organizational commitment, and turnover intention) in the context of bus drivers. Results: Using self-reported survey data collected from a sample of 320 Taiwanese urban bus drivers, results reveal that role overload and work-family conflict (as job demand factors) positively relate to emotional exhaustion, and organizational support (as a job resource factor) is negatively associated with emotional exhaustion. Emotional exhaustion has negative effects on both job satisfaction and organizational commitment. Job satisfaction positively leads to life satisfaction, whereas organizational commitment negatively relates to turnover intention. Conclusion: This study concludes that role overload and work-family conflict as two stressors related to job demands and organizational support as the job resource factor to affect emotional exhaustion which further influence well-being in bus driver context. The moderating effects of both extraversion and neuroticism on the relationship between job demands and emotional exhaustion are evident.
