한국은 지난 20년 동안 지방 자치제를 도입했지만, 대도시권 이외 지방자치단체들은 발전 속도 저하와 인구유출 등의 문제에 여전히 시달리고 있으며, 지역사회의 해체가 더욱 가시화되고 있다. 이에 지방자치단체 주민들이 지역 문제를 스스로 해결하게끔 지원하고, 해결 과정에서 지방자치단체라는 공동체의 응집력을 강화하며, 사회를 활성화하기 위한 시급하고 효과적인 정책이 필요하다. 이런 배경에서 마을기업의 개념이 갈수록 중시되고 있고, 지방단체의 해체 현상, 지역 경기의 쇠퇴 등의 문제 해결방안으로 사회적 경제에 대한 연구를 바탕으로 하는 사회기업, 협동조합, 마을기업 등의 개념이 떠오르고 있다. 따라서 본 연구는 지역 활성화를 위한 지역 마을기업 육성정책을 수립하는 데 목적이 있으며, 구체적으로는 다음과 같다. 첫째, 영국과 일본, 그리고 한국의 커뮤니티 비즈니스의 현황, 발전과정을 검토하고 각 발전에서 가지고 있는 문제점을 파악하고자 한다. 둘째, 선행연구를 통해 마을기업이 지역 활성화에 가지고 있는 역할을 살펴보고자 한다. 셋째, 서울시와 고양시에 있는 모범이 되는 마을기업을 사례 분석하고, 이를 토대로 마을기업의 성공 요인 요소를 살펴보고자 한다. 넷째, 연구 결과에 따라 시사점을 제시한다. 그리고 연구 결과에 따른 마을기업의 성공 요인은 다음과 같다. 첫째, 마을기업의 핵심요소는 지역 주민 중심으로 사업 주체를 발전시킬 수 있다. 둘째, 지역 문제와 주민들이 관심이 있는 문제를 해결하기 위한 기업 경영 형태로 적정 이윤의 비영리 형태와 이익의 사회 환원 방식으로 구성되어야 한다. 셋째, 마을 기업은 지역 주민들이 참여해서 자체적으로 제도나 조례의 형태로 규정을 수립하고 자율적으로 이사진을 조직하여 운영할 필요가 있다. 넷째, 주민 조직의 역할과 지도자를 양성하고 중앙정부/자치 단체의 재정 지원과 법률 제도 및 조례의 제정, 마을 운영의 전문 부서 또는 운영 시스템을 수립해야 한다. 다섯째, 마을기업의 성공 요인으로서 마을기업 네트워크 간 순환 지원 구조의 형성이나 지역 내 수익 등에 의한 이미지 제고 및 기업 간 협의회 구성을 강화해야 한다. Korea has introduced a local autonomy system for 20 years, but local governments other than metropolitan areas are suffering from problems such as slow development and population outflow, and the dissolution of local communities is becoming visible. That is why local residents need urgent and effective policies to solve local problems on their own, strengthen the cohesion of local government communities and revitalize society in the process of solving them. Against this backdrop, the concept of village enterprise is becoming increasingly important. More and more studies on the social economy have occurred in the concept of social enterprises, co-operatives and village enterprises, so new measures for problems such as the dissolution of local organizations and the decline of the local economy are being put forward Therefore, this research is an important basis for the establishment of the village enterprise development policy for the revitalization of the region, and the purpose of this study is to establish the local village enterprise development policy for the revitalization of the region because of its high value. Specifically: First, we would like to review the current status and development process of community business in both countries, Japan, and Korea and identify the problems we have in each development Second, we would like to examine the role that village enterprises have in revitalizing the region through prior research. Third, we would like to analyze examples of exemplary village enterprises in Seoul and Goyang, and examine the factors that contribute to the success of village enterprises based on the analysis. Fourth, suggest implications according to the results of the study. The success factors of the village enterprise according to the results of the study are as follows. First, the core element of the village enterprise can develop the business entity around the local residents. Second, it should consist of a non-profit form of appropriate profits and a social return method of profits in the form of corporate management to solve regional problems and problems of residents' interest Third, the village enterprise needs to be operated autonomously by local residents to establish their own regulations in the form of the system or ordinance and to organize and operate the board of directors. Fourth, the roles and leaders of the residents' organizations shall be nurtured and the financial support of the central government/autonomous organizations and the finance of legal systems and ordinances, the specialized departments or operating systems of village operations shall be established. Fifth, as a success factor in village family business, the formation of circular support structure between village enterprise networks or the enhancement of image by profit in the region, and the formation of inter-business council should be strengthened.
Stock-Bond Return Dynamics and the Expected Country Stock Returns
Sungjune Pyun 한국재무학회 2023 한국재무학회 학술대회 Vol.2023 No.11-1
Stock and bond prices move together with greater country-specific risk. Bonds hedge global growth expectation risk with low country-specific risk, resulting in a negative stockbond correlation. However, as country-specific risk increases, bonds do not effectively hedge stocks because higher local growth expectation tends to lower inflation, leading to higher stock and bond prices. Consequently, countries with greater country-specific risk exhibit a higher stock-bond correlation. Investments in countries with a positive stockbond relationship outperform those with a negative relationship by 7–11%. The superior performance is not driven by investments in a fixed set of countries.

The flashlight sintering characteristics of inkjet-printed nanosized copper ink on paper substrates with varying pattern widths and intervals were studied. The copper nano particles (CNPs) synthesized using vapor self-assembled multilayer (VSAM) method to prevent oxidation, were produced with ink and patterned on a paper substrate through inkjet printing. The width and interval of the Cu patterns were varied from 350 to 550 μm to investigate the flashlight sintering tendency. It was confirmed that the Cu pattern resistivity decreased as the width of the Cu pattern increased, with decreasing interval between the Cu patterns. For the Cu pattern with the largest width and narrowest interval, the lowest specific resistivity was 6.43 × 10–6 Ω∙m. For auxiliary heating at 80 °C, the lowest resistivity of the Cu pattern was 7.10 × 10–6 Ω∙m with improved adhesion to the substrate, and this resistivity was 6.2 times lower than that without auxiliary heating. The temperature gradient of the CNP pattern during the flashlight sintering process was predicted using custom made simulation program. Therefore, the experiments and simulations confirmed that the wider the width and the narrower the interval between patterns, the flashlight sintering characteristics improved through higher heat generation by minimizing heat spreading.
Fusion of Multiple Gait Features for Human Identification

Gait recognition has recently attracted increasing interest from the biometric community. In this paper, we propose a simple new feature called multi-bipolarized contour mean (MBCM) for gait recognition. The proposed MBCM feature consists of four components: (1) the vertical positive contour mean, (2) the vertical negative contour mean, (3) the horizontal positive contour mean, and (4) the horizontal negative contour mean. We fuse the proposed gait features at a feature level to improve recognition performance. The proposed recognition system is evaluated with the NLPR gait database.

Various dry active wastes (DAWs) have been accumulated in nuclear power plants since the DAWs are mostly combustible. KAERI has developed a thermochemical treatment process for the used decontamination paper as an operational waste to substitute for incineration process and to decontaminate radionuclides from the DAWs. The thermochemical process is composed of thermal decomposition in a closed vessel, chlorination of carbonated DAWs, separation of soluble chlorides captured in water by hydroxide precipitation, and immobilization of the precipitate. This study examined the third and fourth steps in the process to immobilize Co-60 by fabricating a stable wasteform. Precipitation behaviors were investigated in the chloride solution by adding 10 M KOH. It was shown that the precipitates were composed of Mg(OH)2 and Al(OH)3. Then, the glass-ceramic wasteform for the precipitates were produced by adding additive mixtures in which silica and boron oxide were blended with various ratios. The wasteform was evaluated in terms of volume reduction ratio, bulk density, compressive strength, and leachability.
