In this paper, the effects of a metamaterial slab with negative permeability in a magnetically coupled wireless power transfer system (WPT) in the overall performance are analyzed quantitatively in terms of the effective quality factors of the loop resonators and coupling coefficient considering the slab losses, based on an equivalent circuit. Using the ideal metamaterial slab(lossless slab), the WPT efficiency is improved considerably by the magnetic flux focusing. However, the practical lossy slab made of RRs or SRRs limits the significant enhancement of WPT efficiency due to the relatively high losses in the slab consisting of RRs or SRRs near the resonant frequency. For the practical loop resonator, other than a point magnetic charge, using the practical lossy metamaterial slab in order to improve the transfer efficiency, the width of the slab needs to be optimized somewhat less than the half of the distance between two loop resonators. For the low-loss slab with its loss tangent of 0.001, the WPT efficiency is maximized at 93 % when the ratio of the slab width and the distance between the two resonators is approximately 0.35, compared with 53 % for the case without the slab. The efficiency in case of employing the high-low slab(loss tangent: 0.2) is maximized at 61 % when the slab ratio is 0.25.

Open banking, the global trend of the financial industry, is the driving force behind various innovations in the financial market in the future. The right policy direction and detailed tasks are important for triggering the differentiation and reunion of the financial industry. The purpose of this study is to investigate and analyze the background of open banking, domestic and international trends, and Korea's open banking policy. The policy directions and tasks for successful settlement and activation of open banking system are carefully suggested. Open banking is a policy to allow third party provider(TPP) access to bank accounts and open payment functions under the explicit consent of the customer. The opening of the open banking era is expected to begin competition and cooperation between banks and fintech companies in earnest, thus enhancing the competitiveness of the financial industry and contributing to the utility of financial consumers. To this end, policymakers should make every effort to advance open-ended financial settlement infrastructure, open banking legal grounds, and minimize side effects such as customer data leakage and poor financial system stability. Banks and fintech companies will need to focus on scattered customer financial information on a single platform and develop it into a convergence and discrimination of true financial services.

The issue presented in this paper are as follows: 1. Legislative actions of welfare-related law for the exceptional children. The legislative base for the evolution has been yet weak and ambigous at best for a formalization of what should be considered accepted practice and effective action in providing handicapped child and their parents educational rights and equal protection of the law. And they are under remote control of partial factor subject to social welfare law for children, and public law for education, promotion law for the exceptional child education, protection law for public aids. 2. Organization of government for the welfare services for the exceptional children. There is no sing of a push toward consolidation of effort for the welfare service of the exceptional children in this country that seeks to recapture a sense of unity, of coherence, of completeness from a reality made up of discontinuous fragments of humanitarian effora This presently that. as for the education of the exceptional child, by the section of the exceptional education in MOE (Ministry of Education), and/or as for welfare services and promotion actions, by the section of child welfare in MHSA (Ministry of Health and Social Affairs). One door type operation rooted in the specialization, and limited resources to evolve multi-purpose agencies that undertake to provide a broad range of tangible and concrete services, as well as supportive counselling and assessment, under a single management which plans and directs the allocations of resources, should be followed. 3. Facilities and recruitment of teachers for the exceptional children. In this country there are 54 facilities for special services, 56 schools for the exceptional education, and 3 colleges and equavalents that provide teacher training services leading to certification with IIO annual graduates. However, curriculum for exceptional children should be rearranged and reconstructed. Conclusion; Only as for social welfare institutions in community, this country produced a succession of specific purpose activities, over period of time, that accumulated to form the present network of hundreds of social welfare organizations and facilities Periodically major efforts were launched to revitalize or to improve the help-giving system. But they lack specialization to be effective, and the nature of multi-purpose center tends to be vague for the classified handicapped. Therefore, there, should be linkage between policy maker and community services to maintain some coherenty in preventive care, treatment, and after cares. At last, the effects of the current concept "the exceptional child" involved with their families, and their neighborhood should be considered in view of the people who consist about 25% of the total population.

In Korea, previous certification of water supply infrastructure was mainly focused on economical and physical aspects. Recently, hygienic safety of water supply service has become a sensitive and important issue to our people for evaluating the water quality with growth of economy and education system. According on water quality in 497 Korean water supply facilities, pH values in the supplied water have ranged between 5.8-8.5. However, little is known about metal leachability at the pH conditions observed in the real water supply systems because a fixed pH condition (pH 7.0) has been used in the current standard method, 'Hygienic Safety Testing Method', in water supply. In this work, we examined the effects on heavy metal leachability with pH differences in the water supply pipes which are typically used in Korea. As a result, the amounts of metal leachability were tended to increase when pH levels were decreased. Especially at pH 5.8, Cu leachability from Cu pipes was found to exceed the public health standard level even after applying a normalization factor (NF) given by the current Korea standard method. The Cr and Cu leached from stainless steel pipes, Cd, Pb, Cu, and Zn from Cu-based pipe fittings, and Zn from Zn-based pipe fittings were exceeded the Korean hygienic safety standards while, after applying the NF, concentrations of the leached metals were satisfied with the current Korean standard. The findings from this work provide implications on the needs of reforming the current hygienic safety standard methodology.

Certificates of Origin(C/O) are necessary to gain benefits from preferential tariff treatment under the Free Trade Agreement(FTA). The C/O can be issued by issuing authorities or by exporters themselves. Recently, due to signed FTA such as Korean-EU FTA, issuance of self-declared C/O by exporters is increasing. In order to be qualified to issue self -declared C/O, exporters are required to acquire Approved Exporter status. An Approved Exporter is only required to present an invoice to substitute the certificate. The invoice contains an Approved Exporter number and a declaration that states the goods comply with the origin requirements. Either certification or notarization is not necessary. In result, the exporters are responsible for application of a preferential tariff under the self-declared C/O which issued incorrectly, even if it is not intentional. Therefore, in this paper, we studied authorization for Approved Exporter status and the practical use of its status. If companies obtain more Approved Exporter status, the effects of FTA would be maximized due to application of a preferential tariff under the C/O.

The purpose of this study was to analyzed the effects of educational recognition sub-factors (necessity, utility, value, cost, adequacy) on the field usability and satisfaction and the correlation between each factor for 220 applicants who have taken the national technical certificate of cosmetologist (make-up). In the practical courses of makeup certificate, the most-used course was selected as beauty makeup. It found for improvement need cause there was a high necessity and there was a low recognition of the cost, the number of annual written and practical test in the recognition of certification education. In field usability 'Beauty make-up utilization' showed high recognition, and it showed high satisfaction for acquisition of certificate satisfaction, 'The salary' showed low recognition. The necessity, cost, adequacy among educational recognition sub-factor of the national technical certificate had a significant positive effect on the field usability and satisfaction, and showed the most effect as adequacy on the field usability and the cost on the satisfaction. Therefore, efforts are needed to reduce acquisition costs of certificate and improve highly available theories and technique for segmentation and specialization of make-up certificate.

The purpose of this study was to examine the effectiveness of family-friendly management in 501 family-friendly certified firms and to analyze organizational and social outcomes outlined by the firms. In addition, this study aimed to discover ways to promote family-friendly management by investigating the effects of ongoing support to certified firms, including family-friendly consulting and workplace training. The results showed that certified firms administer family-friendly workplace policies at a satisfactory level, while their management of policy indices and outcomes were not effective. The finding suggests that family-friendly management indices need to be aligned with firms' substantial outcomes. An improved organizational image and trust were major organizational outcomes of family-friendly management, and an enhanced CEO perception and a culture centered on gender-equality were significant social outcomes. These outcomes need to be promoted to attract organizations to engage in family-friendly management. The finding further implies the important roles of organizations in cultivating family-friendly environments in society. Finally, the certified firms with ongoing consulting and training support exhibited higher levels of family-friendly management and organizational and social outcomes. This study sheds light on the importance of long-term, systematic efforts by organizations in fostering family-friendly management and achieving organizational and social outcomes.

This study was intended to suggest the future direction of catering companies in line with the new normal in the era of COVID-19. The purpose of this study is to investigate the effect of image and awareness of signs for safe restaurant on behavioral intentions. As a result of testing the hypothesis, first, it was found that the image of the sign for the safe restaurant had a significant effect on the recognition. Second, the image of the safe restaurant sign has a significant effect on trust. Third, it was found that the awareness of the signs for the safe restaurant had a significant effect on trust. Fourth, trust had a significant effect on behavior intention. Fifth, it was found that the image and awareness of the sign in the safe restaurant did not have a statistically significant effect on the behavioral intention. Sixth, it was found that the image of the sign at the safe restaurant and the awareness of the sign at the safe restaurant completely mediate trust and have a significant effect on the behavioral intention. The results of this study show the need for publicity activities to raise awareness of the safe restaurant certification and the importance of giving trust to consumers.
