Purpose The purpose of this study is to design a regional electricity planning model rather than the existing single region ones and verify its usefulness. The regional electricity planning model is to determine both electricity distribution among regions and power plant planning at the same time satisfying regional demands and distribution networks. Design/methodology/approach This study made a regional electricity planning model by integrating power plant planning and electricity distribution among regions. The regional electricity planning model is formulated into a linear programming problem, and coded and run using the OSeMOSYS, one of open source energy systems. Findings According to the empirical analysis result, this study confirmed that the regional electricity planning model proposed in this study deducts the unfairness among regions in view of electricity and green house gas. In addition, the model is expected to be used in evaluating and developing the national policies concerning fine dust and/or green house gas.

A major effect of electronic commerce on the Internet is that it reduces transaction costs and creates an efficient market. Thus, an information strategy for developing of regional economy must be changed toward 21st century of electronic commerce era. In this paper, we present an information strategy for activating the electronic commerce of regional small and medium-sized business organizations. The paper stresses creation of a network organization comprising local government, regional business organizations, universities, research institutes, and citizens' coalitions as groups of organizational actors. Necessary conditions of a successful network organization in electronic commerce are to build the public key infrastructure for developing the trust of transactions among partners, and to create an information center to manage a web of partners. In the network organization, the information center must play critical roles as a creator of value and the certification authority in order to issue and manage participants' electronic certificates.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic is a public health emergency posing unprecedented challenges for health authorities. Social media may serve as an effective platform to disseminate health-related information. This study aimed to assess the extent of social media use, its impact on preventive behavior, and negative health effects such as cyberchondria and information overload. Methods: A cross-sectional observational study was conducted between June 10, 2020 and August 9, 2020 among people visiting the outpatient department of the authors' institution, and participants were also recruited during field visits for an awareness drive. Questions were developed on preventive behavior, and the Short Cyberchondria Scale and instruments dealing with information overload and perceived vulnerability were used. Results: The study recruited 767 participants with a mean age of about 45 years. Most of the participants (>90%) engaged in preventive behaviors, which were influenced by the extent of information received through social media platforms (β=3.297; p<0.001) and awareness of infection when a family member tested positive (β=29.082; p<0.001) or a neighbor tested positive (β=27.964; p<0.001). The majority (63.0%) of individuals often searched for COVID-19 related news on social media platforms. The mean±standard deviation scores for cyberchondria and information overload were 9.09±4.05 and 8.69±2.56, respectively. Significant and moderately strong correlations were found between cyberchondria, information overload, and perceived vulnerability to COVID-19. Conclusions: This study provides evidence that the use of social media as an information- seeking platform altered preventive behavior. However, excessive and misleading information resulted in cyberchondria and information overload.

본 연구의 목적은 2003년 지역산업연관표의 거래자료와 외관상무관한회귀(Seemingly Unrelated Regression:SUR) 모형을 이용하여 지역수출의 결정요인을 분석하는 것이다. 노동생산성, 규모의 경제, 해외수출입은 지역내 지역간수출에 정(+)의 영향을 주며, 시장규모는 수출대상지의 시장규모가 커질수록 지역간 수출이 증가하는 것으로 나타났다. 반면, 지역간 수출의 경우, 지역간 거리가 늘어날수록 수출이 줄어드는 것으로 분석되었다. 이러한 결과는 지역수출을 확대하고 궁극적으로 지역경제 활성화를 도모하기 위해서는 노동숙련도 향상, 규모의 경제 달성, 시장규모 확대, 지속적인 해외수출 증대 및 물류비 감소 등에 대한 정책이 필요하다.

이 연구는 부산지역 서민금융기관의 영업기반을 분석하는데 목적이 있다. 1980년대 후반 이후 지역금융을 활성화하기 위한 논의가 본격화하였지만 서민금융기관은 관심을 끌지 못하였다. 지방은행과 기업금융이 주된 관심사였기 때문이다. 금융위기 이후 지역금융시장이 수요자시장으로 변화되고, 경영사정이 크게 악화되면서 서민금융기관은 구조조정의 대상으로 되고 있다. 그러나 서민금융기관이 지역금융시장에서 어떠한 역할을 수행하는지에 대한 분석은 거의 없다. 이 연구는 그것이 양적 및 질적인 측면에서 지역금융시장에서 중요한 역할을 행하고 있으며, 특히 은행신용에 접근이 제약된 지역의 영세기업과 서민가계에 대한 금융을 공급함에 있어 매우 중요한 역할을 하고 있다고 주장한다. 이 연구는 서민금융기관은 서민을 위한 금융기관이라는 기존의 막연한 인식을 실증분석을 통해 확인하고 있으며, 서민금융기관이 지역주민과 지역경제에 밀착된 경영을 하게 된 사정도 이론적으로 검토하고 있다.

본 연구의 목적은 지역화와 정보화를 기저로 하고 있는 지역정보화의 수행과정에 공공도서관을 활용함으로써 지역공공도서관의 활성화를 유도하고자 함에 있다. 이는 지역정보화의 기본개념과 공공도서관의 기능이 여러 가지 측면에서 상호 일치되는 내용을 가지고 이기 때문이다. 지역정보화의 수행과 공공도서관의 활성화라는 이중의 효과를 획득하기 위해 본 연구에서는 지역도서관이 갖는 사회적 기능을 정보화 수단으로 활용하는 것과, 커뮤니티 네트워크 개념을 전략적 방법으로 제시하였다. 특히 이들 계획은 오늘 날 농촌지역의 복지 및 개발 사업으로서, 범국가적인 관심의 대상이 되고 있는 시대적 상황과도 무관하지 않음을 고려한 결과이다.

To enhance the usability of smart agriculture, methods for utilizing smart farm data are required. Therefore, this study proposes a scheme for utilizing regional smart farm data by linking it to services. The current status of domestic and foreign smart farm data collection and linkage services is analyzed. To collect and link regional smart farm data, necessary data collection, data cleaning, data storage structure and schema, and data storage and linkage systems are proposed. Based on the standards currently being implemented for regional smart farm internal data storage, a farm schema, environmental information schema, facility control information schema, and growth information schema are designed by extending the crop schema and crop main environmental factor information database schema. A data collection and management system structure based on the Hadoop Ecosystem is designed for data collection and management at regional smart farm data centers. Strategies are proposed for utilizing regional smart farm data to provide smart farm productivity improvement and revenue optimization services, image-based crop analysis services, and virtual reality-based smart farm simulation services.

For planning and developing rural regions, it is very important to understand and utilize regional characteristics including social, demographic, and economic aspects. The purpose of this study is to find effective analysis techniques and provide a procedure design for mining regional characteristics in South Korea through reviewing and analyzing 41 related studies. The engaged research methods can be classified into five categories (PCA+CA, PCA, CA, GIS, and PCA+GIS) with the combination of three methodologies: principal component analysis (PCA), cluster analysis (CA), and geographical information system (GIS). The combination of PCA and CA occupied about 40 % of research methods used in related studies. The analysis tool of Korean Rural Information Supporting System (KRISS) is designed based on the outcomes of this study and applied to classify the regional capacity of agriculture using agricultural census data (2000) for evaluating its applicability.
