The purpose of this study was to identify the effects of stress factors of student pilots on mental health, and to reduce the safe and efficient misconduct education and psychological disharmony by identifying the psychological buffering role of stress coping style and social support. In order to achieve the research purpose, a research model and hypothesis were presented based on previous studies, and regression analysis and mediation effect verification were conducted through a questionnaire survey of 202 student pilots. As a result of the analysis, factors such as flight stress, values stress, professor stress, and friend relationship stress have been shown to affect emotional conditions or psychological well-being. Also we found that the parameters of disengagement coping, family/friend support and organization Support had a mediating effect on the factors between student pilot stress and psychological health. Therefore, student pilots need to manage problems and negative emotions that may cause from flight training, value distractions, professor and friendships' relationship and it is suggested that organization support for training and safety related to emotional support and delinquency of family and friends.

Gellan gum as a natural polysaccharide has good heat resistance, acid resistance and enzymes resistance. However, one of the drawbacks of gellan gum might be the lower mechanical strength. In this work, gellan gum scaffolds were mixed with poly(lactic-co-glycolic acid) (PLGA) microsphere in order to improve mechanical properties. The gellan gum scaffolds with various contents of PLGA microsphere were prepared for the regeneration of disc tissues. To evaluate the mechanical strength of hybrid structure of gellan gum and PLGA microsphere, compression strength of the fabricated scaffolds was measured. MTT analysis, SEM observation, histological evaluation and RT-PCR were performed to confirm the effect on the cell growth and extracellular matrix secretion. As a result, it showed the best cell proliferation and extracellular matrix secretion in gellan gum sponge containing 50% PLGA microspheres. In conclusion, this study confirmed that the hybrid structure of gellan gum and PLGA microspheres was found suitable in regeneration of the intervertebral disc.

This study examined the factors that affect the turnover intention of newly graduated nurses. The basic data was utilized for developing a personnel resource maintenance program for newly graduated nurses. New nurses working at a general hospital in City D were surveyed from May 2016 to April 2018. The questionnaires completed by 232 volunteers were analyzed using the IBM SPSS 21.0 program, and the descriptive statistical analyses included t-tests, ANOVA, Scheffe test, Pearson's correlation coefficient, and multiple regression analysis. Among the general characteristics of new nurses, their workload displayed significant differences in proactive behavior, organizational commitment, social support, and the turnover intention. There was a negative correlation between organizational commitment, employer support, peer support, and the turnover intention. The influential factors were organizational commitment and workload, and the explanatory power for turnover intention was 36.1%. Higher organizational commitment, along with appropriate workload, led to a lower turnover intention. Therefore, appropriate work allocation through work analysis is necessary to lower the nurses' turnover intention. Developing a program that can increase proactive behavior and implementing various intervention strategies can increase the participation of newly graduated nurses when establishing and implementing appropriate hospital policies.

The purposes of this research was to examine the relationship between two forms of satisfaction, commitment and turnover intentions at organization, job. Also consistent with the Meyer et al(1993) notion of the three-component model of organizational commitment. Although researchers have examined organizational commitment in relation to a wide range of variables, there has been no discriminant validity of commitment at occupation and job. The purpose of the present article, are to compare the relation between satisfaction forms, commitment forms and turn intentions forms. Confirmatory factor analysis supported the proposed distinction between the three forms of commitment and two turnover intentions forms at the measurement level in the distribution industry(N=156). Results using structural equation analysis with AMOS18 showed that job satisfaction had an positive impact on job commitment forms. Organizational satisfaction positive impact on two turnover intentions forms. However it revealed that no significant relation between organizational satisfaction and job commitment, job commitment and job turnover intentions.

Today's employees are facing various socio-emotional problems due to the lack of appropriate supports and intervention in the workplace. These problems, however, cause considerable stress and inflict fatal damage on the quality of the employees' lives. Thus, this study analyzed the negative effects of the employees' socio-emotional problems on their stress, depression, and a sense of self-esteem. As a result, the study has identified that the problems occurred widely in the work life area such as job-related problem, predicament of retirement, workplace violence, family life area such as family relationship, child education, crisis problem, and lastly culture and health related area. This study also found that the socio-emotional problems in the three areas were the main stressors after all and they once again negatively affected depression and a sense of self-esteem. However, the role of social support, which is known to have the buffering effect on depression and a sense of self-esteem, was not sufficiently proved. This strongly implies that traditional social supports necessarily have limitations to overcome employees' socio-emotional problems in hand and thus systematic intervention toward the troubled workers in the organizational level must be required.

Articular cartilage has an intrinsic difficulty in recovering damages, which requires its tissue engineering treatment. Demineralized bone particle (DBP) contains various bioactive molecules. It is widely used biomaterials in the field of tissue engineering. We developed the synthetic/natural hybrid scaffolds with poly(lactide-co-glycolide) (PLGA) and solution of DBP. The chondrocytes were seeded on the PLGA-DBP scaffolds and MTT assay, morphological observation, biological assay for collagen, sGAG, and RT-PCR were performed to analyze the effect of the DBP on cell viability and extracellular matrix secretion. In SEM observation, we observed that PLGA-DBP scaffolds had uniform porosity. As MTT assay showed scaffolds containing DB solution had higher cell viability then only PLGA scaffolds. The PLGA-DBP scaffolds had better ECM production than PLGA scaffold. It was proven by the higher specific mRNA expression in the PLGA-DBP scaffold than that in PLGA scaffold. These results indicated that PLGA-DBP scaffolds might serve as potential cell delivery vehicles and structural bases for in vitro tissue engineered articular cartilage.

This study, centering on public enterprises, has been conducted from 4 different perspectives such as grasping the effects that the factor precedent of the multi-rater feedback affects on the usefulness of evaluation and the effects that the usefulness of evaluation affects on the organizational achievement, checking on whether there is any discrepancy among the effects affecting on the usefulness of evaluation in accordance with the degree of advance training on the evaluation system, and being what kind of effects the usefulness of valuation that the appraised eventually understand affects on the organizational achievement. As result of the study, the factor precedent that are confidence of the appraisers and the support from CEO reasonably affected on the usefulness of evaluation, but the standard referred to evaluation was not reasonable. It became resultantly clear that the confidence of the appraisers held the effect of control from the verification of whether there is the effect of control between the factor precedent and the usefulness of evaluation in accordance with the degree of advance training. However, it turned out that the standard referred to evaluation and the support from CEO held no effect of control. As result, It was possible to confirm that the usefulness of evaluation in this study affects directly or indirectly to the organizational achievement such as organizational immersion, job satisfaction, self development opportunity, and organizational revitalization as influenced by the prior factors, and the advance training was partially effective on the adjusting effect.
