In this study, a meta-analysis was conducted on a total of 34 studies (14 academic papers, 20 dissertations in academic journals) conducted in Korea from 2000 to 2020 in order to understand the relationship between work-family conflict, work-family enhancement and social support. (N=17,530). Work-family conflict and work-family enhancement were used for analysis by dividing the direction into the case where the direction was not distinguished, the direction from work to home, and from home to work. The social support was divided into family, spouse, organization, supervisor, coworker, and not classified according to support resource, and a subgroup analysis was conducted. Depending on the type of support, a subgroup analysis was conducted by dividing into emotional, instrumental, informational, and appraisal support. As a result of the analysis, both support resources and types showed a significant relationship with work-family conflict and work-family enhancement. It was confirmed that the most significant relationship was changed according to each sub-factor and the direction of conflict and enhancement. Based on the above research results, the implications and limitations of this study were presented and directions for future research were suggested.

Purpose: This cross-sectional survey study explored the moderating effect of social support between hierarchy-oriented nursing organizational culture and turnover intention in clinical nurses. Methods: Data were collected using self-report questionnaires from 240 nurses working at three general hospitals in February 2018. Hierarchy-oriented nursing organizational culture, turnover intention and social support were measured using 5, 6, and 8 items, respectively, of validated instruments. Descriptive analysis and hierachical multiple regression were conducted using SPSS/WIN 21.0. Results: Nurses rated $3.66{\pm}0.50$ for hierarchy-oriented nursing organizational culture, $3.40{\pm}0.64$ for turnover intention, and $3.77{\pm}0.56$ for social support respectively. Nurses' turnover intention was positively correlated with hierarchical organizational culture, but negatively with social support. The moderating effect of social support was not significant in the relationship between hierarchical nursing organizational culture and turnover intention. Conclusion: It is required to improve the hierarchy-oriented nursing organizational culture. Institutional preparation and education are urgently needed to strengthen the boss and peer support for clinical nurses and finally to reduce turnover intention.

The purpose of this study was to identify the factors that could overcome the crisis and adversity of the nursing care provider through understanding the effect of job adaptation on the turnover intention of the nursing care provider and to contribute to the various problems of the nursing care provider in the long term. In order to confirm this as an empirical research task, risk factors and protection factors, general characteristics of the survey subjects, job adaptation and turnover intention were selected, and the risk factors and protective factors of caregivers' As a mediator. So Seoul. The results of the questionnaire survey were as follows: 291 caregivers in the elderly medical welfare facilities in Gyeonggi area. First, as the relationship between the risk factors and protective factors of occupational caregivers and occupational adaptation were more severe, the higher the maladjustment of the workplace culture, the more the job satisfaction and organizational commitment were adversely affected. The emotional support, The higher the information support, the more satisfied and satisfied the job. Second, the relationship between the risk factors of the caregiver and the protective factors and the turnover intention, the higher the conflict of caregivers, the more unstable the workplace, the more difficult it is to adapt to work culture, Respectively. Finally, as a result of verifying the mediating effect of occupational adaptation on the relationship between risk factors and protective factors and turnover intention of caregivers, job satisfaction, which is a sub-factor of job adaptation, It is shown that they play mediating roles only in the relationship between stress and turnover intention, and do not play a mediating role in the relationship between protective factor self - efficacy and social support and turnover intention. In other words, if caregivers feel satisfaction about their job, they can be less stressed on their jobs, improve their self-efficacy, and have a positive attitude toward social support. Also, it was found that the more the caregiver 's immersion into the organization, the less job stress and turnover intention decreased, but the self - efficacy and social support perception were not influenced. Based on this, the director of the facility should strive to stabilize the operation of the facility and provide high-quality services by seeking ways to improve conflict resolution and adaptation to the workplace culture so that nursing care workers can adapt to their work. And it is required to develop active management strategies and institutional support for improving job satisfaction and organizational commitment of caregivers.

T-cell deficiency may occur in various clinical conditions including congenital defects, cell/organ transplantation, HIV infection and aging. In this regard, the development of artificial thymus has recently been attracting much attention. To achieve this aim, the development of techniques for 3D culture of thymic stromal cells is necessary because thymocytes grown only in a 3D thymic microenvironment can be differentiated fully to become mature, immunocompetent T cells; the same cannot be achieved for thymocytes grown in 2D. This study aimed to develop a nanotechnology-based 3D culture technique using polymeric scaffolds for thymic epithelial cells (TECs), the main component of thymic stromal cells. Scanning electron microscopic observation revealed that the pores of both PCL and PCL/PLGA scaffolds were filled with TECs. Interestingly, TECs grown in 3D on polydopamine-coated scaffolds exhibited enhanced cell attachment and proliferation compared to those grown on non-coated scaffolds. In addition, the gene expression of thymopoietic factors was upregulated in TECs cultured in 3D on polydopamine-coated scaffolds compared to those cultured in 2D. Taken together, the results of the present study demonstrate an efficient 3D culture model for TECs using polymeric scaffolds and provide new insights into a novel platform technology that can be applied to develop functional, biocompatible scaffolds for the 3D culture of thymocytes. This will eventually shed light on techniques for the in vitro development of T cells as well as the synthesis of artificial thymus.
