Along with the rise in the value of cryptocurrency, the interest of the blockchain is very high. However, most people do not understand cryptocurrency and blockchain very well. In addition, due to this lack of understanding of the technology, ideas about how blockchain technology can be applied in the food industry may not come up. Therefore, this content describes the advantages of blockchain technology in terms of security, starting with the understanding and operation method of cryptocurrency and blockchain technology, and briefly describes the development of a blockchain system. And simple examples of how this blockchain technology can be applied to other industries are summarized, and examples used in the food industry are summarized. Finally, it was insisted that using such a blockchain technology can provide safe food to consumers.

Notwithstanding the big potential benefits from interorganizational information systems (IOS), not very many companies have realized these benefits. In an attempt to explain this phenomenon, this study proposes a new construct of IOS asymmetry which refers to the asymmetry in information transparency between supply chain (SC) partners. When there is IOS asymmetry in SC relationships, IOS may not facilitate seamless information exchange among SC partners. Instead, IOS asymmetry may result in SC inefficiencies due to a lack of information sharing. The objective of this study is to empirically investigate whether IOS asymmetry exists in practice and whether it influences SC performance negatively. The data was collected from 130 matched pairs of upstream SC partners in manufacturing industries. The results show that IOS asymmetry indeed decreases overall SC performance. Also, the relationship between IOS asymmetry and SC performance is strengthened under the conditions of high environmental uncertainty.

National R&D programs are managed and operated by institutes under different ministries. The R&D information created through these programs are designed and constructed heterogeneously both semantically and structurally. Therefore, integrated collection, analysis and application of the information through the interoperability of information at the national level becomes nearly impossible, and redundant production and operation of R&D information becomes a general problem. The Office of Science and Technology Innovation has started the construction of the National Science and Technology Information System(NTIS), which is based on the interoperability and sharing of R&D information, to resolve these issues. In this paper, we propose a method to construct a system for sharing national R&D information held by different ministries while minimizing the effect on the autonomy of the institutes involved.

Blockchain technology has the potential to revolutionize trust models and business processes in a variety of industries. However, it is considered to be the initial stage of the system that pursues autonomy rather than efficiency, and it is necessary to monitor and inspect the distributed ledger technology from the price and introduction time as compared with the existing relational DB transaction technology. However, domestic and foreign private sectors have already been activated by applying block-chain technology in the national domain, and the block chain is devoid of doubt that it is an exaggerated technology, characterized by the invariance of the record, transparency, and autonomous execution of business rules. It has begun to be utilized in history, identity, certification and auditing in the financial industry as well as various industries. In this paper, we analyze the problems such as security weakness, insufficient regulatory environment, technical consensus and lack of common standard. In addition, the business sense and possibility of the block chain technology is expected to be the innovation of the industrial ecosystem by entering into the reality system from the concept through monitoring the actual introduction performance in the field of copyright, logistics, health care and environment.

Central banks communicate with the market through a statement on the direction of monetary policy while implementing monetary policy. The rapid contraction of the global economy due to the recent Covid-19 pandemic could be compared to the crisis situation during the 2008 global financial crisis. In this paper, we analyzed the text data from the monetary policy statements of the Bank of Korea and Fed reflecting monetary policy directions focusing on how they were affected in the face of a global crisis. For analysis, we collected the text data of the two countries' monetary policy direction reports published from October 1999 to September 2020. We examined the semantic features using word cloud and word embedding, and analyzed the trend of the similarity between two countries' documents through a piecewise regression tree model. The visualization result shows that both the Bank of Korea and the US Fed have published the statements with refined words of clear meaning for transparent and effective communication with the market. The analysis of the dissimilarity trend of documents in both countries also shows that there exists a sense of synchronization between them as the rapid changes in the global economic environment affect monetary policy.

This paper aims at analyzing the current status, characteristics and problems of housing development project finance firstly, and secondly, examining the policy measures in order to enhancing the housing development project finance systems. The main results of this paper are as follows. Project finances are very activated in the housing development projects, especially, apartment development, since 2001. But most of housing development project finance are not virtual project finance, but conditional corporate finance, because most of project finance didn't uses bankruptcy remote. Therefore, the main policy measures in order to activate effective growth of project finance are, first, institutionalizing of project finance, second, enhancing the feasibility study capabilities of finance companies, third, using the real estate funds effectively, and forth, networking housing development project finances with long-term mortgage finances.

우리나라 제조업(製造業)의 수직적(垂直的) 구조(構造)는 선진공업국에 비하여 소(小) 영세기업(零細企業)의 비중이 월등히 높은 피라미드형의 형태를 보이며 80년대말 이후 소기업군의 확대는 더욱 두드러지고 있다. 이처럼 소기업의 비중이 높아진 것은 제조업체들이 가격경쟁력(價格競爭力)을 높이기 위하여 생산비용이 높게 드는 자체생산(自體生産)을 가능한 한 줄이고 임금(賃金)이 낮은 중소기업으로 생산공정을 이양해 왔기 때문이다. 소기업 비중이 높은 분업구조는 가격경쟁력이 중시되어 생산을 분업화해야 하는 경제체제에서는 높은 효율성(效率性)을 발휘한다고 평가할 수 있다. 90년대에 이르러 중소기업이 저가(低價)의 생산요소(生産要素)를 조달받기 어려운 경제여건이 조성되면서 중소기업의 경영불안이 높아지는 등 가격경쟁력을 유지하기 위한 생산분업체제(生産分業體制)는 한계(限界)에 도달한 것으로 보인다. 따라서 대기업과 중소기업간 분업도 기술(技術) 중심의 분업관계(分業關係)로 전환되어야 할 단계에 이르렀다고 볼 수 있다. 그러나 종전과 같이 소기업(小企業)에 의존하는 분업구조(分業構造)로는 기술분업(技術分業)이 정착되기 어렵다. 왜냐하면 연구개발, 전문인력의 고용 등 기술개발과 관련된 기업활동에는 생산량에 관계없이 고정비용(固定費用)이 들어서 기술개발 비용과 위험을 분산시키려면 기업의 생산규모가 상당히 커져야 하기 때문이다. 이는 소기업 중심의 분업구조가 중견기업(中堅企業)중심의 구조로 개편(改編)되어야 함을 의미한다. 중견기업이 육성되려면 첫째, 대기업과 직거래하는 중소업체(中小業體)의 수(數)가 축소되어야 한다. 거래업체수의 과다는 기업규모를 영세하게 만드는 가장 직접적 요인이기 때문이다. 그러나 거래업체의 정리과정에서 기존업체들이 중소기업 보호여론을 등에 업고 반발할 수 있고, 대기업이 교섭력을 강화하기 위한 수단으로 악용할 수 있으므로 객관적이고 투명한 정리기준의 제시가 전제되어야 한다. 둘째, 대기업의 중소기업에 대한 대폭적 자본참여(資本參與)가 허용되어야 한다. 대기업의 자본참여는 중소기업 지배를 강화할 것으로 우려되어 현재는 극히 부분적으로 허용하고 있으나, 개방경제하에서는 대기업과 국내 중소기업간의 협력관계를 유지시키는 효과적 수단으로 작용하게 될 것이다. 셋째, 은행 등 금융자본(金融資本)의 중견기업에 대한 투자(投資) 활성화(活性化)가 필요하다. 금융자율화로 금융기관의 수익성이 강조되는 상태에서 금융자본이 거래업체의 주주(株主)로서 참여하면 경영정보를 손쉽게 파악할 수 있어 우량업체의 신속한 육성이 가능해질 수 있다.

This paper investigates plans to expand distribution channels for books by installing a book vending machine at convenience stories for the vitalization of the publishing culture and industry. After establishing the meaning of convenience stories and the concept of a book vending machine, the researcher identified a need for the installation and management of a book vending machine at convenience stories. This plan will promote fairness and transparency in book sales through the convenience store system and push forward outsourcing between the publishing industry and the convenience store industry, the expansion of omnichannel service for consumers, and experiential values for clients to increase their customer satisfaction. The composition of the book vending machine will take the smart library form for its management with a universal design applied to a kiosk program. In the study, the researcher schematized this process and conducted a survey with 310 adults to search for practical management plans for a book vending machine. In the future, more research on the diversification of sales and distribution channels for publications such as the installation of a book vending machine at convenience stores will hopefully contribute to the growing amount of reading per capita and promotion of a reading environment for people according to the vitalization of the publishing culture and industry.

The purpose of this paper is to investigate the relationship between foreign ownership and firm value. Based on the sample of 3,398 firm-year observations in the period of 2000 to 2007, we find evidence that foreign ownership is positively associated with firm value measured by the market-to-book ratio. In addition, we employ simultaneous equation system where both foreign ownership and firm value are treated as endogenous variables. Simultaneous regression models indicate that the foreign ownership affects firm value, but not vice versa. The positive effects of foreign ownership on firm value result from monitoring and disciplining roles played by foreign investors. Many Korean firms have been run by an owner-manager while monitoring provided by institutional equity holders has been limited. Therefore, Korean firms are expected to suffer from more severe agency costs caused by the conflicts of interest between owner-managers and outside investors. Our empirical results support the notion that foreign investors play an important role in enhancing corporate transparency and improving corporate governance.
