This study tried to suggest a systematic improvement plan to prepare a civil safety insurance operation and management system by reviewing the operation and management status of civil safety insurance, which is operated and managed by each local government autonomously. In this study, the problems of the current civil safety insurance were analyzed by dividing them into the lack of systematic management of insurance items, overlapping coverage between insurance items, and deviations in compensation limits. As a systematic improvement plan, it was suggested to secure the systemic management of guarantee items, standardize compensation standards, prepare an integrated operation and management system, and provide financial support for local governments with poor financial independence. Since the problems and improvement plans for the civil safety insurance analyzed as described above are formed by exchanging and receiving a complex mutual influence, the institutional improvement plan for the operation and management system of the civil safety insurance is not only a specific part of the study, but also comprehensively current citizens. Based on the results derived from the analysis of safety insurance, it is concluded that alternatives must be found.

Detecting the features of significant patterns from their own historical data is so much crucial to good performance specially in time-series forecasting. Recently, a new data filtering method (or multi-scale decomposition) such as wavelet analysis is considered more useful for handling the time-series that contain strong quasi-cyclical components than other methods. The reason is that wavelet analysis theoretically makes much better local information according to different time intervals from the filtered data. Wavelets can process information effectively at different scales. This implies inherent support for multiresolution analysis, which correlates with time series that exhibit self-similar behavior across different time scales. The specific local properties of wavelets can for example be particularly useful to describe signals with sharp spiky, discontinuous or fractal structure in financial markets based on chaos theory and also allows the removal of noise-dependent high frequencies, while conserving the signal bearing high frequency terms of the signal. To data, the existing studies related to wavelet analysis are increasingly being applied to many different fields. In this study, we focus on several wavelet thresholding criteria or techniques to support multi-signal decomposition methods for financial time series forecasting and apply to forecast Korean Won / U.S. Dollar currency market as a case study. One of the most important problems that has to be solved with the application of the filtering is the correct choice of the filter types and the filter parameters. If the threshold is too small or too large then the wavelet shrinkage estimator will tend to overfit or underfit the data. It is often selected arbitrarily or by adopting a certain theoretical or statistical criteria. Recently, new and versatile techniques have been introduced related to that problem. Our study is to analyze thresholding or filtering methods based on wavelet analysis that use multi-signal decomposition algorithms within the neural network architectures specially in complex financial markets. Secondly, through the comparison with different filtering techniques results we introduce the present different filtering criteria of wavelet analysis to support the neural network learning optimization and analyze the critical issues related to the optimal filter design problems in wavelet analysis. That is, those issues include finding the optimal filter parameter to extract significant input features for the forecasting model. Finally, from existing theory or experimental viewpoint concerning the criteria of wavelets thresholding parameters we propose the design of the optimal wavelet for representing a given signal useful in forecasting models, specially a well known neural network models.

현재 급변하는 환경 속에서 각 국가는 일자리 창출 및 기술 경쟁력 강화를 위한 노력을 지속하고 있다. 특히 벤처기업 및 창업기업에 대한 지원과 활성화 정책은 국가 경쟁력을 높이는 역할을 하는 것으로 알려져 있다. 경쟁 심화로 비즈니스 수명이 짧아지고 고객들의 요구가 다양화되는 환경의 불확실성이 확대되는 가운데 기업은 적절한 대처를 해야 한다. 우선 기업은 스스로 내부 역량을 강화하는 노력을 하는 것이 중요하다. 그러나 벤처기업은 내부 자원 및 역량 등이 부족하여 외부 환경으로부터의 지원이 기업의 생존으로 연결될 만큼 중요하다고 볼 수 있다(Timmons, 1994). 기업의 경쟁력 강화를 위해 국가 차원에서 재정지원 및 인증제도를 운용하고 있다. 그러나 재정지원은 상황에 따라 기업의 자생력을 낮출 수 있으므로 연구개발 지원 및 창업교육과 같은 비 재정적 지원이 벤처기업 성장에 장기적으로 도움이 된다고 보았다(Aghion et al., 2012; 전미미·고강혁, 2021). 비 재정적 지원은 사업화, 시설, 공간, 보육, 인력, 인증제도 등으로 구분되는데 본 연구에서는 인증제도인 벤처기업 확인제도의 혜택을 중심으로 확인하였다. 이를 위해 2021년도 벤처기업정밀실태조사 데이터 및 벤처기업의 매출액 데이터를 활용하였으며, SPSS 26.0 패키지와 SPSS PROCESS MACRO를 활용하여 분석하였다. 분석 결과, 벤처기업의 경영환경 수준은 벤처확인제도 혜택이나 벤처기업 역량 수준을 높이는 데는 긍정적인 영향을 주지만, 실질적인 경영성과로 이어지기는 어려운 것으로 확인되었다. 또한 벤처기업의 경영환경 수준과 경영성과 간 관계를 벤처기업 역량 수준이 매개하는 것으로 확인되었다. 결과적으로 단순히 벤처기업의 경영환경 수준이 긍정적이거나 벤처기업에 친화적일지라도 외부 환경으로부터의 지원을 잘 소화할 수 있는 내부 역량이 있는 기업이 경영성과를 높인다고 할 수 있다.

Sharing Economy is the modern main item with ICT Development. Of course sharing economic item is the old and long run mainstream, but by the ICT technological development sharing economy is the fostering and affluent factors in the world economic growth. Though, in Korea, till now sharing economy is minimal, that will growth sharply. We can track various business models of sharing economy. Sharing economy is to buy use right not ownership. With the sharing economic business model wee can make also financial sharing model. In finance model we can divide two kind models. First, we can trace small size lending model with p2p type. And second, we can make financial information transaction model. But till now sharing economic system is not activated, because of many reasons. To activate, first we have to set law and various standards, and also government actively support many sharing economy firms and institutions. To catch up developed countries in the field of sharing economy we have to make aggressive and flexible rules and standards.

The object of this paper is to increase in domestic use of export factoring for small and medium trading companies. Factoring involves a process where a specialized firm assumes the responsibility for the administration and collection of account receivable for its clients. It can be considered a form of short term commercial financing based on selling of trade credit at a discount, or for a prescribed fee plus interest. The youngest and smallest businesses cannot receive working capital for account receivable for export from financial companies, while larger businesses tend to have less need for factoring services. Using export factoring provide a valuable improvement to cash flow and working capital position and can possibly contribute to small business growth and development. There are several suggestions for export factoring to activate in Korea. First, the number of factoring companies need to be enlarge to activate export factoring in trade and financial policies. Second, factoring companies have to perform public relations for trading companies to inform the export factoring system and its advantages. Third, government need to support the system of export factoring with legislation and financial instruments. Forth, trading companies need to be reformed credit inquiry system in terms of expenses and methods by government This paper has attempted to emphasize on export factoring for small and medium size exporting companies and deserves more research by academics, practitioners and trade policy makers.

In recent years, reductions in infant mortality have mainly been accomplished by improving the survival of premature and low birth weight infants, however premature infants still remain at great risk. The purpose of this study was to review the maternal child health service related to premature infants and to provide a future direction for improving maternal child health (MCH) in Korea. We reviewed two MCH services which are directly related to premature infants: 1) a registry and financial support program for families with a premature infant, and 2) financial support to build neonatal intensive care units in rural public hospitals. Suggestions are made for the development of a national vital signs record system to identify high risk infants and to monitor the trends in infant mortality due to prematurity. Prevention efforts and preconception care for childbearing women is also an important strategy to reduce the rate of preterm births. Finally, we need consider long-term follow-up plans for premature infants for a successful transit to the special education system. Developing MCH policy related to premature infants that decreases the occurrence of premature may decrease infant mortality, and also improve maternal and child health services.

Recently, the number of closed rural schools is increasing due to the decrease in school age population. This study aims to comparative analysis of utilization policies for closed schools in Korea and Japan. The results are as follows. First, Both Korea and Japan was expected to increase the number of closed schools since the standard of abolition of small schools has been strengthened. Second, In Korea, it was possible to know the detailed information of closed schools through 'Eduinfo' website, but it was hard to know the detailed information of utilization cases of closed schools. On the other hand, Japan not only provided information about the unused school facilities but also introduced the utilization cases of closed schools and financial support system for utilization of closed school. It was characterized by linking with the information of unused schools and company, NPO, elderly welfare facility, etc. Third, In korea Superintendent established plans to use closed schools to respond flexibly to local circumstances. Japan simplified the procedures for closed schools to promote the utilization of closed schools. Finally, In Japan, there was various financial support system. But in Korea, it supported the cost of subsidy reduction, free loan, maintenance and management and operation.

Despite the fact that the sourcing process in B2B e-Marketplaces is one of the most important tasks, the evaluation and selection process of suppliers have been ad-hoc based and mainly dependent on the experience of sourcing managers' subjective knowledge. To remedy the problem, we developed a decision support System (called Wise - I) that helps sourcing managers evaluate suppliers in a more systematic way. The system reflects company's strategy and know-how by adopting company enforced weighted scores for different factors and employing a more scientific method of considering factors other than price and on-time delivery rate, utilizing the AHP method. This paper reports the effectiveness of the system as well as the detailed description of the system. To investigate the effectiveness of the system, we collected information through interview and questionnaire survey. The information was also augmented through the firm key index system, which monitors average delivery lead time and on-time delivery rate. The result indicates that the system leads to the efficiency of purchasing section and the transparency of buying process, therefore reduces delivery time and cost.
