최근 햄버거 병을 시작으로 살충제 계란파동, E형간염 소시지까지, 급증한 식품안전 사고는 국민식품소비를 위축시키고 막연한 공포감 조성으로 올바른 식품섭취를 유지할 수 없도록 한다. 국민소득 증가와 더불어 식품의 안전성에 대한 소비자의 관심이 높아지고 있으며, 소비자는 보다 안전한 먹거리를 공급해줄 것을 요구하고 있다. 이에 대한 대응책을 마련하고자 정부와 식품업계, 학계 등은 고심하고 있다. 본 연구는 4차산업혁명에 발맞추어 식품안전분야에 ICT기술을 활용한 생산에서 소비자까지의 식품공급망의 안전관리를 체계화하는 FSMS(Food Safety Management System)을 구성해보고 그를 통한 식품의 안전도를 시험분석을 통해 효과를 검증하는 것이 목적이다. 본 연구는 FSMS의 기술요소인 빅데이터, 온습도IoT센서 등을 Pilot Test하고 FSMS 도입전과 도입후의 검체를 체품하여 공인식품시험검사기관에서 검체의 미생물수 분석을 통해 최종적으로 FSMS의 도입효과와 모형도를 제시하였다.

The successful implementation of green supply chain management(GSCM) practices requires a level of cooperation that can be difficult to conduct. Despite this challenge, limited scholarly attention has been paid to exploring how the implementation of GSCM practices can be effectively facilitated and enhanced through accumulated social capital with suppliers. Based on social capital theory, this study postulates that supplier network characteristics derived from social capital with key suppliers can be critical antecedents of GSCM, which in turn enhances the firm's environmental performance. To test hypotheses, data were collected from 330 firms in 15 countries, and structural equation modeling was employed. Results show that GSCM improves environmental performance, and structural and cognitive social capitals of the supplier network act as antecedents and lead to GSCM implementation.

The recent spread of the corona pandemic and a temporary surge in demand for consumer goods have resulted in an increase in port cargo volume, and the resulting port congestion is coupled with a shortage of labor in the port, exacerbating the global supply chain chaos. Supply chain disruptions will increase logistics costs and ultimately increase global inflationary pressures. In this situation, the role of the port, which is the nodal point between land and sea, is gradually becoming more important. And fully automated ports that are operated unmanned are evaluated as being able to respond stably and flexibly by reducing operational risks in situations such as COVID-19. Therefore, this study compared the operational performance of fully automated and non-fully automated terminals within the same port before and after the corona outbreak, and analyzed the fully automated terminal was stable in actual operation. As a result of the analysis, the fully automated terminal showed stable operating efficiency in all aspects of operational performance compared to the non-fully automated terminal even under severe port congestion due to COVID-19.

빙축열 시스템과 같은 열교환 시스템을 이용하여 심야의 전력 경부하 시 주간에 이용할 냉방부하를 축열하였다가 주간에 공급함으로써 전력의 평준화와 전력 설비의 효율적 운용을 기할 수 있어 전력의 안정적인 수급과 에너지의 효율을 극대화할 수 있다. 하지만 빙축열 시스템의 제어 운전을 전적으로 운전자의 경험에 의존하는 경우에 충분한 냉방 부하를 공급하기 위한 잉여축열에너지가 비경제적으로 많아져서 빙축열 시스템의 경제성이 저하되고 사용 효과가 낮아지는 문제점이 많이 발생되고 있다. 경제적인 활용 효과를 고려하여 빙축열 시스템을 효율적으로 운용하기 위해서는 냉방부하량이 기후 특성에 의해 결정되므로 기후를 정확하게 예측하고 이를 토대로 다음날의 시간별 냉방부하를 예측하여 적정한 축열량을 결정하여야 하는 어려움이 따른다. 이러한 문제를 해결하기 위해 본 연구에서는 신경망을 이용하여 기상 데이터를 토대로 다음날의 온도와 습도를 예측하고 예측된 온도와 습도 및 냉방부하 실적 자료를 기반으로 신경망을 이용하여 시간별 냉방부하를 예측하는 알고리즘을 제시하였다. 제안된 냉방 부하예측 알고리즘에 의해 구축된 한국전력공사 속초생활연수원의 부하예측모델을 이용하여 온도, 습도, 냉방부하를 예측한 결과 기존 방법에 의한 것보다 우수한 예측 성능을 보였다.

The trend of business work that is related to supply chain changed into e-business using the electronic document However, the small and medium enterprise organizations still use huge volume of paper document, especially in private sector. Recently, the need for eco-friendly and low cost logistics becomes increasing. For this, it has expanded to exchange or to use e-document rather than the paper or manual processing in supply chain business. Therefore, this paper proposed the electronic access system for supply chain by business process modeling. If it is using the proposed system, it can be saving the exchanged or the scanned document to system, and user can utilize that document on just accessing system whenever they need the document. We believe it might reduce the burden of each organization because they don't need to save large volume data to their system or place. Furthermore, the benefits will effect across the national as well as global.

Recently, many global companies are making efforts to realize the sharing economy based on the establishment of a global supply chain and the established global supply chain. There are various methods for realizing the sharing economy, but among them, a lot of effort is being made to promote the sharing economy of companies through the shared logistics system, especially logistics efficiency. In order to realize the corporate sharing economy, companies are required to find ways to apply ICT-based shared logistics systems. Therefore, this study aims to improve the logistics efficiency of logistics companies in order to increase the efficiency of ICT-based sharing economy in logistics companies. To this end, we would like to present the current status and operation of the domestic shared logistics system for the application of the ICT-based shared logistics system, and suggest the operation plan of the shared logistics system through ICT linkage with the domestic shared logistics system. It is judged that various needs required in the global supply chain can be satisfied by presenting an efficiency plan for ICT-based shared logistics.

By applying AI-based efficient inventory management and logistics optimization technology using the smart factory's production plan and manufacturing data, the company's productivity improvement and customer satisfaction can be expected to increase. In this paper, we proposed a system that collects data from the factory's production process, stores it in the cloud, and uses the manufacturing data stored there to apply AI-based supply chain optimization technology later. While the existing system supported approximately 10 to 20 data types, the proposed system is designed and developed to support more than 100 data types. In addition, in the case of the collection cycle, data can be collected 1-2 times per second, and data collection in TB units is possible. Therefore This system is designed to be applied to the existing factory of past in addition to the smart factory.

In order to respond to supply chain threats, active research and development efforts are underway for software tamper prevention technologies such as Secure Boot and management systems like Software Bill of Materials(SBOM). Particularly, the Trusted Computing Group (TCG) is introducing standards for Trusted Platform Module(TPM) to provide a secure and trustworthy computing boot environment. This paper emphasizes the need for introducing secure booting technology for cryptographic modules to ensure that they remain safe and provide reliable functionality even in the face of supply chain threats. Furthermore, it analyzes vulnerabilities in cryptographic modules verified by the ISO/IEC 19790 standard and proposes security requirements for secure booting of cryptographic modules to address these vulnerabilities.
