In this paper, related studies were investigated by dividing them into cost-benefit analysis, security continuity services, and SW-centric calculations. The case analysis was conducted on A institutions in the United States, Japan and South Korea. Based on this, an improvement model was prepared through comparison with the current system. The SCS(Security Continuity Service) performance evaluation system-based information protection service cost calculation model is proposed. This method applies a service level agreement(SLA) and NIST Cybersecurity framework that are highly effective through cost-effectiveness analysis and calculates consideration based on characteristics, performance criteria, and weights by information protection service. This model can be used as a tool to objectively calculate the cost of information protection services at public institutions. It is also expected that this system can be established by strengthening the current recommended statutory level to the enforceability level, improving the evaluation system of state agencies and public institutions, introducing a verification system of information protection services by national certification bodies, and expanding its scope to all systems.

In China, with the rise of third-party payments such as WeChat Pay and Alipay, the traditional business of banks has been greatly affected. Banks can encourage and expand QR code payments to merchants. Therefore, it is meaningful to analyze and study the QR code work of banks. The purpose of this study is to analyze the effect of the execution of the zero-rate of the comprehensive payment QR code combined with the payment cycle and Funds Transfer Pricing (FTP) on commercial banks in China. Based on the manually collected customer data of Chinese commercial banks, this paper conducts a case analysis combined with the calculation method of financial indicators. As a result of the study, it was found that commercial banks need to continue to implement the policy as the advantages of introducing the integrated QR code fee rate 0 policy are greater than the disadvantages. This paper provides feasible suggestions on how to quickly occupy the offline payment market for commercial banks, which has guiding significance for commercial banks' marketing decisions. Presently, there are few studies on the zero-rate subsidy policy implemented by Chinese commercial banks.

The purpose of this case study is to examine and compare the basic characteristics of quality assurance systems of the 3 leading countries in international higher education: Australia, Canada, and the Netherlands. The comparative analysis of the three cases demonstrates that, taking a more commercial stance on the international education service market, quality assurance systems of the 3 countries aim at facilitating effective promotion of student recruitment and enhancing their national brand image as advanced knowledge society. Consequently, rules and regulations of their systems are concerned primarily with strengthening institutional capacities to educate international students effectively, and, ultimately, improving their learning experiences in the host countries. Compared to these foreign cases, the newly-adopted quality assurance system in Korea places too much emphasis on internationalization process itself, thereby neglecting evaluation of educational capabilities of higher education institutions. Further implications for improvement of the Korean International Education Quality Assurance System(IEQAS) are discussed.

The purpose of this study was to explore the night duty experience on the personal life of fixed night shift nurses working in various health care delivery systems. Data collection was conducted through three focus group interviews from September to October 2022, The subjects of the study were 13 nurses working fixed night shift. For analysis, all interviews were recorded and transcribed and analyzed using qualitative content analysis. In results, 5 themes, 11 categories and 24 subcategories were derived. The five themes were 'it's a voluntary choice', 'efforts to adapt to the shift', 'awareness about fixed night shift', and 'hope to improve the system'. The study aims to help understand fixed night shift work and systems by showing various night-duty experiences on the personal life of the nurses and to provide basic data for preparing measures to improve the system.

The purpose of this study is to analyze empirically the effects of changes in policies of the construction industry on the entry and exit in the construction industry and to present the direction of changes in construction industry policies based on the analysis results. The purpose of this study is also to present by analyzing the factors influencing the increase and decrease of builders in the actual construction market. The results of the survey indicate that for general contractors in Daegu and Gyeongbuk, which are mostly small and medium-sized construction companies, the strengthening of registration standards (capital, technicians, etc.) has a significant impact on market entry and exit. However, on the other hand, many of the construction policies implemented to eliminate unqualified contractors in the construction market have had the effect of increasing the number of unqualified contractors. This suggests that construction policies in the construction cycle have not achieved their objectives.

The purpose of this research is to explore the explanatory factors of preference for the universality of the welfare system at the time of expanding the welfare system. In particular, considering endogenous problem that may occur in the process of analyzing the causal relationship between subjective perception and preference for welfare policy, the 2SLS regression analysis using instrument variables was attempted in this research. The key findings of this research were as follow. First, the groups who are opposed to the welfare state expansion, for example high income earners, low risk group, and employer/self-employer, prefer the more universal welfare systems. Second, the negative perception of welfare policy and recipients, which is stronger in older generation who experienced a much longer period of industrializaion, have a negative effect on preference for the universal welfare system. Last, we find that the endogenous problem arise in this research and distort the estimated regression coefficients. Therefore, subsequent studies must be mindful of this problem when they explain attitudes with attitudes.

Local governments within the boundaries of a state need increasing flexibility to satisfy diverse economic, social, and environmental goals in their particular geographical setting. However, many candidates in the local election in South Korea tend to see local politics as an extension of national-level politics. In particular, this paper mainly deals with how the voters' evaluation of a president's performance has influenced subnational elections in South Korea. Our analysis suggests that the fate of candidates in subnational elections is shaped by the performance of the incumbent president in both economic development and foreign affairs.

콩은 중요한 식량 작물로 단백질, 기름 및 이차대사산물인 이소플라본을 다량으로 함유하고 있다. 이소플라본은 폴리페놀의 일종으로 일부 암을 예방하며 심혈관 질환을 완화하는 데에도 도움을 준다고 알려져 있다. 콩에 인위적으로 식물호르몬인 ABA를 처리할 때 이차대사산물인 kaempferol의 함량이 증가한다고 보고 되었다. 따라서 이 연구는 식물 생장조정제 처리가 콩잎의 이소플라본 함량에 미치는 영향을 알아보기 위해 수행되었다. 연구는 밀양 남부작물부 유리온실에서 수행되었으며, 콩(품종:선풍)은 와그너포트 1/2000에 1주 2본 파종하여 재배하였다. Ethephone(500, 1000, 2000 ppm)과 ABA(100, 200, 400 ppm)를 사용하였으며 각각 R2, R5, R7기에 처리하였다. 처리 후 잎을 5일 간격으로 3회 채취하여 이소플라본 6종과 쿠메스트롤의 함량을 분석하였다. 초고성능 액체 크로마토그래피(Acquity UPLC H-Class system, Waters)를 사용하여 분석하였다. 이소플라본 함량은 R5 단계에서 전반적으로 높게 나타났으며, R2 및 R7 단계에서는 무처리와 유사한 수준을 보였다. ABA를 처리하였을 때 생장조정제 간의 차이가 에테폰보다 더 큰 것으로 나타났다. 쿠메스트롤 함량은 처리시간에 따라 R7, R5, R2 순으로 높은 것으로 확인되었으며, 처리시간이 지날수록 함량이 증가함을 알 수 있었다. 생장조정제 처리에 쿠메스트롤 함량은 ABA보다 에세폰 처리 시 더 높은 경향을 보였다.
