Small local businesses such as corner shops and street markets have been severely impacted by the COVID-19 pandemic and declining consumption. A community currency is a local currency that can be used to exchange for one of the local currencies within an online community. Community currencies can be effective not only in supporting small businesses, but also in helping the local economy more vibrant, benefiting consumers in the community. An important goal of Community Currency is to foster a vibrant local economy by building mutually beneficial relationships between local business owners and customers. The purpose of this study was to identify how the existing community currencies of participating SMEs and self-employed in Seoul and Gyeonggi-do metropolitan areas contributed to commercial revitalization by category and to suggest a new or better approach to community currency operation. It also focused on presenting the best solutions for the future direction of mobile community currencies, measures that are better than current currency operations, revitalize the community and develop the economy.

본 연구는 2009년 근로자 직업능력개발 훈련 지원에 대한 제도 개편이 한국의 이러닝 산업에 미친 영향에 대해 살펴보고, 그에 따른 어려움은 어떤 것들이 있는지 진단해보았다. 분석 결과, 엄격해진 원격훈련 지원 심사 기준으로 인해 원격훈련 기관이 상당수 줄어들게 되었고, 이는 나아가 이러닝 시장의 전반적인 위축이라는 문제점 등이 초래된 것으로 나타났다. 이에 본 연구는 각 어려움들을 극복할 수 있도록 스마트 러닝, 창의적 융합인력 양성 등의 내용이 포함된 근로자직업능력 개발 관련 법제도의 개선 방안들을 제시함으로 창조 경제 실현에 기여할 수 있는 정책추진 방향에 대해 제언하고자 한다.

공유경제가 향후 10년을 지배할 지속가능한 시스템, 그리고 세상을 변화시킬 10가지 아이디어 중 하나로 평가되고 있는 가운데, 본 연구에서는 공유경제가 도서관과 어떤 관련성이 있으며, 공유경제의 핵심모델로서 도서관은 공유경제 활성화에 어떻게 기여할 수 있을 것인지에 대해 제안하고자 하였다. 이를 위해 공유경제관련 문헌분석 및 공유경제 실현 사례 등을 종합적으로 분석하였으며, 그 결과는 다음과 같다. 첫째, 도서관은 수세기 동안 정보 및 도구를 공유해 온 공유경제의 성공적 모델로서 도서관이 공유경제를 리드할 수 있는 기관이 될 수 있을 것으로 분석되었다. 둘째, 도서관은 무한상상실 및 스마트워크센터 기능을 하는 장소 및 공간의 공유, 도서관의 각종 자원은 물론 리틀프리도서관을 통한 물품의 공유, 그리고 참고서비스 및 각종 지식의 공유를 통해 공유경제를 실현할 수 있을 것으로 보인다. 셋째, 도서관에 공유경제를 실현할 수 있는 가능성은 무궁무진하다고 할 수 있는데, 그 역할을 적극적으로 해내고 성패를 좌우하는 것은 사서라는 것이다. 향후에는 도서관 공유경제 실현사례의 성과를 측정하는 연구가 수행될 필요가 있다고 본다.

The increase in the number of large cities and the size of their population sharpens attention to the new role of cities as entities to ensure a high-quality, safe and modern life of citizens, which has become significantly more active in recent years. The rapid spread of smart cities in the modern world has actualized the issue of analyzing their success and assessing the role of various factors in this. Every success of a smart city is always the result of a unique combination of the most modern technologies, environmental and social initiatives, skillful and consistent management, as well as available human potential. The purpose of the article is to analyze the success factors of smart cities based on the generalization of the results of the most famous ratings. In order to identify the impact of various factors, primarily intellectual, on the success and leadership positions of smart cities, the following ratings were consistently analyzed: Smart City Index (SCI), City in Motion Index (CIMI), Global Power City Index (GPCI), Global Cities Index (GCI), Global Cities Outlook (GCO). They have a different list of indicators and main pillars (dimensions), but all ratings take into account aspects such as: governance, ICT, mobility, functionality, human capital, etc. The highest correlation coefficient, that is, the strongest linear relationship of the CIMI index was found with such factors as: Human capital, Economy, Governance and Technologies. Summarizing the results of the TOP 20 smart cities according to different ratings allowed us to confirm that the list of leaders is very similar in all ratings. Among those cities that are in the TOP-20 in all five indexes are: London, Sydney and Singapore. There are four indices: New York, Paris, Tokyo, Copenhagen, Berlin, Amsterdam, Melbourne. Achieving leadership positions in smart city rankings is always the result of a combination and synergy of certain factors, and first of all, it is the quality of human capital. The intensity and success of the use of information and communication technologies in locality management processes, city planning and improvement of the city's living conditions depend on it.

With the development of smart grid technology, it has become a hotspot to increase benefits of both residential users and electric power companies through demand response technology and interactive technology. In this paper, the game theory is introduced to the interaction between residential users and an electric company, making a mutually beneficial situation for the two. This paper solves the problem of electricity pricing and load shifting in the interactive behavior by building the game-theoretic process, proposing the interaction strategy and doing the optimization. In the simulation results, the residential users decrease their cost by 11% mainly through shifting the thermal loads and the electric company improves its benefits by 5.6% though electricity pricing. Simulation analysis verifies the validity of the proposed method and shows great revenue for the economy of both sides.

Purpose - This study introduces a methodology for finding the optimal tracking error of active stock funds. Tracking error is commonly used in risk budgeting techniques as a concept of cost for alpha creation. Design/methodology/approach - This study uses a post-optimal smart beta portfolio that maximizes alpha under the given tracking error constraint. Findings - As a result of the analysis, the smart beta strategy that maximized alpha under the constraint of 0.15% daily tracking error shows the highest IR. This means the maximum theoretically achievable efficiency. In this regard, a fixed-effect panel regression analysis is conducted to evaluate the active efficiency of domestic stock funds. In addition to control variables based on previous studies, the effect of tracking error on alpha is analyzed. The alpha used in this model is calculated using the smart beta portfolio according to the size of the constraint of the tracking error as a benchmark. Contrary to theoretical estimates, in Korea, the alpha performance is maximized under a daily tracking error of 0.1%. This indicates that the active efficiency of domestic equity funds is lower than the theoretical maximum. Research implications or Originality - Based on this study, it is expected that it can be used for active risk management of pension funds and performance evaluation of active strategies.
