This study aims to analyze the reserch result about housing history of multi-disciplines especially archeology, cultural anthropology, folklore, geography, archtecture and dwelling science. Each discipline has acted an important role to develop the research on housing history, even though they have some limitations. They usually failed in clarfying the relationship among physical housing, habitants and social environment. In order to overcome these limitations, this study suggests microsociological approach, so called "Housing Adjustment Model".del".uot;.

Purpose: This study was to investigate the influence of male nurses' gender role conflict and job satisfaction on their organizational commitment. Methods: Data were collected through a mixed method design using structured questionnaires (N=162) and a sequential qualitative interviews (N=8) from 2nd October, 2012 to 7th February, 2013. Data analysis included t-test, ANOVA, regression with SPSS/WIN 19.0 program and a qualitative thematic analysis. Results: Factors affecting participants' organizational commitment were job satisfaction and marital status which accounted for 36.2% of the total variance. In particular, low job satisfaction was not correlated with low organizational commitment despite lower job satisfaction. Three main themes connoting meanings of ambivalence were extracted from the data: desiring for the better future in spite of the current difficulty, strengthening their masculinity in tandem with complementing femininity in the midst of gender role conflict, leading their organization at times, and enduring hard work with responsibility for raising their family as a head of household. Conclusion: The findings indicate that male nurses' adjustment to the organization is controlled by ambivalence. It is essential to understand sociocultural contexts of male nurses as a minority in nursing fields for further research.

The duty of construction clients in WSH (Workplace Safety and Health) system was included in the amendment of Occupational Safety and Health Act (enforced on 16 January 2020), which was estimated the shift of paradigm in the prevention of construction accidents. The purpose of this paper is to introduce the analysis results of construction clients' role in the construction project, which were performed by authors over the recent years in order to impose the duty on construction clients, and to suggest their role according the plan, design, and construction stage. Utilizing the systematic literature review process based on Meta analysis, the related papers were selected. For the selected papers, related domestic and foreign regulations, and other prominent report, the construction clients' role was analyzed by reflecting the experts' advice. Results show that the construction clients should control the designer and contractor for implementing the WHS system during the whole process of the construction project. They should supply sufficient source and time to ensure the workers' safety. In the plan stage, the key role of construction clients is to identify intensively controlled hazard and risk reduction plan and to transfer the results. In the design stage, their key role is to select the designer with the capacity in WSH and to assist the designer for the safety design. The main key role of construction clients in the costruction stage is to select the contractor with specialty in WSH including a contract reflecting the WSH requirement and to check implementation of WSH plan, WSH cost, WSH education, and accident report. In addition, it is thought that the construction clients' participations in the site WSH activity and adjustment of safety and health problem among contractors can be effect in the prevention of construction accidents.

The purposes of this research were to find out general trends of employed women's stress and to investigate the differences and effects of related variables. The data were obtained through 239 employed women living in Kwangju and Chonnam. The major findings were as follows : 1) Employed women's scores of stressor, stress cognition and distress were under medium but coping scores were relatively high. 2) Significant differences in employed women's stressors were found according to age, income, job satisfaction, and family life cycle. Stress cognition differed according to job adjustment conditions and self-esteem. Also distress related with job conditions and object. Stress coping levels were different according to income, job conditions, self-esteem, and sex-role attitude. 3) In analyzing the causal effects among related variables, employed women's stressors were affected by job satisfaction and age. Also stress cognition were influenced by job satisfation and self-esteem. Job conditions showed significant effects on distress and self-esteem, sex-role attitudes showed on coping. Conclusively job satisfaction, self-esteem and gender equality were most important variables for employed women's stress. (Korean J of Human Ecology 2(1) : 25-37 1999)

Korean traditional house has inherented construction characteristics that contain human requirements with the adaptation to nature's order. As for traditional buildings, there are a lot of facilities like palaces, Buddhist temples, Confucianism architectures, government facilities, etc. Among them, housing construction is not only closely connected to our lives, but also plays an important role to connect our lives from the past to present. The master room in a traditional korean house is responsible for playing a center role of the residential life which implies the traditional values responsible for multi-functions and it is also the sphere of the living space. Therefore, this thesis considers the residential environmental adjustment method and the behaviors centered around the main buildings of Jeonnam Province. And also investigates the main reason for windows and doors formation. From this, we would like to further evaluate the master room life, and the inner space constructions following the spacial and organizational analysis of windows and doors. We would like to analyze the space organization methods, environmental adjustment methods and the usages of traditional buildings. Using the modern interpretation as basis, we would like to use the foundation materials to reflect single family housing plans.

In order to improve spectral efficiency and reduce power consumption for reconfigurable intelligent surface (RIS) assisted wireless communication systems, a joint design considering irregular RIS topology, RIS on-off switch, power allocation and phase adjustment is investigated in this paper. Firstly, a multi-dimensional variable joint optimization problem is established under multiple constraints, such as the minimum data requirement and power constraints, with the goal of maximizing the system energy efficiency. However, the proposed optimization problem is hard to be resolved due to its property of nonlinear nonconvex integer programming. Then, to tackle this issue, the problem is decomposed into four sub-problems: topology design, phase shift adjustment, power allocation and switch selection. In terms of topology design, Tabu search algorithm is introduced to select the components that play the main role. For RIS switch selection, greedy algorithm is used to turn off the RISs that play the secondary role. Finally, an iterative optimization algorithm with high data-rate and low power consumption is proposed. The simulation results show that the performance of the irregular RIS aided system with topology design and RIS selection is better than that of the fixed topology and the fix number of RISs. In addition, the proposed joint optimization algorithm can effectively improve the data rate and energy efficiency by changing the propagation environment.

This study examines the direct impact of ESG ratings on investment efficiency among Korean firms from 2012 to 2022, as well as whether earnings management mediates the relationship between ESG performance and investment efficiency. The key findings are as follows. Firstly, it was found that as ESG ratings increase, a firm's investment efficiency significantly improves, indicating that ESG management has a positive impact on investment efficiency. Secondly, as ESG ratings increase, earnings adjustment significantly decreases, suggesting that ESG investment activities also have a positive impact on firms' earnings management. Thirdly, as earnings adjustment decreases, investment efficiency significantly increases, indicating that earnings management significantly mediates the relationship between ESG performance and investment efficiency. This study demonstrates that higher ESG ratings lead to increased investment efficiency among firms, and earnings adjustmentment plays a significant mediating role in the relationship between ESG performance and investment efficiency.

The purpose of this study is to investigate the influential factors which is related to stress among the children from marrried-immigrant families. The cultural adjustment factor explored as the most affective factor to the children from multi-cultural families. Associated stress with the cultural adjustment, stress which is related to Korean ability presented as the most problematic one. As the conflict related to internalized problems increased as the stress also increased. However, as social support increased as the degree of stress seems to be decreased. For those children, schools work as the safe place compare to the other social environment. Therefore, it would be beneficial to redirect the role and the function of schools for the children from the married-immigrnat families. Various educational opportunity, which is not limited to teach Korean and Korean culture, should be offered to the children as to improve his/her self-esteem.
