In the relationship between the shareholding ratio of National Pension Service (NPS) and the investee firm's value, this study examined the mediating effect of R&D expenditure which its increase can indirectly induce the increase of firm value, and examined the moderated mediation effect of the Stewardship Code implementation which pressures investee firms' to increase R&D expenditure and firm value. Using the Korean listed companies' data from 2016 to 2021, the analysis showed that the R&D expenditure had a partial mediation effect on the relationship between NPS's shareholding ratio and firm value. Also, the analysis showed that the NPS's Stewardship Code implementation had positive moderating effects on following relationships, one between NPS's shareholding ratio and R&D expenditure, and the other between NPS's shareholding ratio and firm value. In all, on the relationship between NPS's shareholding ratio and firm value, the R&D expenditure's mediation effect differs before and after the implementation of the stewardship code, which shows the moderated mediation effect.

The suggestions that follow are about the effectual operating device for private security service. First, in legal and institutional policy, new establishment by law for private security and more support from government is asked. Moreover, the restructuring or M&A between petty companies and the pricing for security service should be performed. Second, in the structural aspect of private security industry, the professional education center for private security guards should be established and the terms of payment and welfare should be improved to the level above standard. In addition, it should be achieved to change the public to have a new and correct understanding of private security and develop the specialized parts suited to the characteristic and ability of each companies. Third, the construction of operating system for private security service should be achieved; recruit system for competent security guards, marketing strategy and enforcement system, widely known confidence to client, normal training system for security guards and post management system for client. This is also to be suited to the characteristic of each companies.

As the environment and rivalry of Regional Agricultural Cooperatives(RACs) becomes more unfavorable, the pressures to enhance organizational performance are strenghthened. Existing studies suggest efficiency improvement through resource sharing(RS) to fix the issue. In this context, I intend to find if RS still increases organizational performance in another form of organization on the basis of 132 business units(BUs) of 45 RACS. According to empirical results, resource similarity between BUs and resource level of BU increases RS respectively, and RS increases BU's performance. The RS also has mediating effects on similarity and resource level into performance. But the overall resource level of RAC has no influence on RS and there is no mediating effect. My contribution is to confirm the efficacy of RS in half-profit organization and to verify determinants and performance implications of RS.

This study is a case study about the Valero Energy Corporation, the largest American independent refinery company, examining the characteristics of human resource management as a union avoidance strategy. The main research questions here are whether union substitution strategy differs clearly from union suppression strategy in the context of Valero Energy. Since the establishment in 1980, the Valero had maintained non-union tradition. The typical examples of human resource management in the non-unionized American companies are easily found in the Valero, such as strong CEO leadership, manpower policy emphasizing corporate culture and teamwork, direct communication between company and individual employees, no lay-off policy and no outsourcing policy of HRM, salary level around average of industry and best level of fringe benefits in the industry, non-union tradition and well-functioned alternative dispute resolution system and so on. Until now, based on tremendous growth and profitability, the company have applied union substitution method adopted by good companies as concrete method of union avoidance strategy instead of union suppression method that marginal enterprise prefers.

As the need for software development manpower increases, various educational programs appear and the popularity of bootcamp style education program for software development increases. However, despite the operations and forms of bootcamp education programs are completely different from the existing software development education programs, there is a lack of research in understanding bootcamp as a software education program. Therefore, this study tried to derive the core elements of the education program through a case study on bootcamp software developer education program. After conducting interviews of 7 members who have completed a series of bootcamp software developer education program X, seven characteristics of bootcamp-type software development education program were derived: intensive theory education, sense of growth and achievement, team project-based learning, community characteristics, peer pressure, stress and fatigue due to short-term learning, and contact-free specialty. Based on the derived characteristics, the advantages and improvements of bootcamp-type education were described, and the direction of the bootcamp-type education program for software developer was discussed.

This study was attempted to identify the essence by confirming the experiences of students who participated in Habuta classes in their major subjects. From November 22, 2022 to December 6, 2022, eight nursing students were individually interviewed to collect data, and the data were analyzed by applying Colaizzi's phenomenological analysis methodology. The study's finding derived 6 categories. The specific categories were 'Coexistence of anxiety and expectation', 'Process of understanding and acquisition', 'Constant burden and discomfort', 'Progress and regression under pressure', 'Sense of security that is being recognized', 'Shift of thought to positivity'. In order for nursing students to participate in Havruta classes positively in the future, appropriate class design, active communication channels between professors and students, and strengthening of instructors' competence are required.

The purpose of this study was to prepare basic data to set the support direction for low-income households in a socioeconomic crisis situation. The study examined the effect of socioeconomic deprivation experience on the longitudinal changes in family conflict and family relationship satisfaction of low-income households. Using five-year data from the 10th to 14th sessions of the Korean Welfare Panel, we examined the longitudinal changes in family conflict and family relationship satisfaction, and the effect of socioeconomic deprivation experience from the reponses of 803 low-income households. We found that the family conflict of low-income households decreased to a weak level with the change of time, and the rate of change in family relationship satisfaction was not meaningful. In the case of families who experienced early socioeconomic deprivation, their initial value of family conflict was higher than that of inexperienced households, and the rate of change was not significant. The results of this study show that when low-income households experience socioeconomic deprivation, they feel psychological pressure and an increase in family anxiety, resulting in high family conflict and low family relationship satisfaction. On the basis of the study results, we recommend extending economic and social assistance to low-income households in the current socioeconomic crisis. The state is also encouraged to help families manage conflicts on their own and resolve problems.

Due to the management innovation policy that was introduced to governmentsupported research institutes (GSRI) in 1998, their employment structure has been continuously changing, with the most notable increase of the number of non-standard researchers and the diversification of employment contracts. This paper examines changes in the employment structure of GSRI over the last 20 years in relation to the introduction and operation of the PBS (project base system), which is a main factor that fundamentally changed the employment structure of research institutes. This paper purposes to analyze the current status of non-standard workers in the science and technology research area through interviewing standard and non-standard researchers. Under the PBS as a principle of organizing their research project, the project-managers cannot help but exploit non-standard researchers to process research within a tight budget. This structure of organizing research projects reinforces the increase of the number of non-standard researchers and diversification of non-standard employment relations. In addition, the wage and working conditions of non-standard workers are getting aggravated in this structure. Considering the characteristics of research institutes, precarious status of non-standard researchers will have negative effects on the development of science and technology.

The major changes in construction environment are that construction project is bigger and more complicated and the power of construction market changes from the supplier to the client or the user. Especially public construction enterprises have advanced to introduce the value engineering (VE) which is one of the cost management based on the owner's leading at the design phase for economical efficiency and quality improvement. According to the these efforts, the implementation of VE was legislated in the revised Construction Technology Management Act in 2000, governmental agencies, local autonomies, and construction public enterprises universally has taken the VE into consideration. In this circumstance, the scope that VE construction applied at 50 billion won projects from 2003 has been extended to 10 billion won projects in 2006. Therefore, the VE construction will be activated in the future. The cost savings and function improvement, which are the purpose of VE are not only construction public enterprises, but also every public client supported from government's budget or owned by the government. Therefore, the purpose of this study is to propose the improved process and performance index of VE for governmental agencies, local autonomies, and construction public enterprises which want to introduce or improve the VE process. This research also suggested the To-be design-phased VE process model. In addition, it suggested the To-be model of design management reflected the To-be design-phased VE process model, which is eliminated two problems reflected for the performance improvement of the As-is model of design management.
