In recent years, the logistics industry has greatly driven the world's economic development. Due to the frequent occurrence of logistics information leakage and forgery, it is necessary to find a solution that can accurately trace the logistics information and ensure the security and authenticity of the logistics information. The birth of blockchain technology has enabled the logistics industry to realize the development from quantitative change to qualitative change. The distributed storage idea, decentralization characteristics, immutable nature, complex encryption algorithm, and other technical characteristics of the blockchain technology make it have a wide range of application prospects in the logistics industry. The purpose of this paper is to apply blockchain technology to the whole chain of logistics information traceability, to indirectly store the corresponding data generated by the logistics circulation link on the blockchain, and to combine the researched consensus algorithm and searchable encryption algorithm to form A set of logistics information traceability system to achieve efficient and accurate traceability of logistics information.

This study focuses on three logistics-related news (Logistics Newspaper, Korea Shipping Gadget, and Korea Shipping Newspaper) in order to present changes in logistics issues, centering on Corona 19, which has recently had the greatest impact in the world. For data collection, two-year news articles in 2019 and 2020 (title, article, content, date, article classification, article URL) were collected through web crawling (using Python's BeautifulSoup, requests module) on the homepages of three representative logistics-related media companies. As for the data analysis methods, fundamental statistical analysis, Latent Dirichlet Allocation (LDA) for topic modeling, and Scattertext were performed. The analysis results were as follows. First, among the three news media related to logistics, the Korea Shipping Newspaper was carrying out the most active media activities. Second, through topic modeling with LDA, eight logistics-related topics were identified, and keywords and significant issues of each topic were presented. Third, the keywords were visually expressed through Scattertext. This is the first study to present changes in the logistics field, focusing on articles from representative logistics-related media in 2019 and 2020. In particular, 2019 and 2020 can be divided into before and after the outbreak of Corona 19, which has had a great impact not only on the logistics field but also on our lives as a whole. For future work, a multi-faceted approach is required, such as comparative studies of logistics issues between countries or presenting implications based on long-term time-series articles.

글로벌 물류기업의 정보시스템은 성과분석을 하여 효율성 증진을 위한 실증적 근거를 기반으로 세부 운영방법을 위한 전략이 요구된다. 본 연구는 물류기업의 핵심역량으로 물류정보서비스를 강화하므로 물류정보시스템의 운영과 정보서비스 등급을 연구대상으로 선정하였다. Logistics Quarterly and Armstrong Association로부터 글로벌물류기업 중 27개 글로벌물류기업을 선정한 후, 이들 기업의 2007년, 2008년, 2009년 까지 매출액, 정보시스템 등급과 정보시스템 운영수, 종업원 수를 투입요소와 산출요소를 이용하여 효율성 분석을 하였다. 효율성의 동태적 변동은 SBM을 이용하였다. 실증분석결과 2007년에 가장 효율적인 DMU는 DB Schenker Logistics.,와 Schneider Log istics, Inc.로 나타났다. 2008년에 가장 효율적인 DMU는 DHL Supply Chain & Global Forwarding., DB Schenker Logistics., Panalpina World Tranport(Holding) Ltd., C.H. Robinson Worldwide, Inc., Hub Group, Inc./Unyson Logistics.로 나타났다. 2009년에 효율적인 DMU는 DHL Supply Chain & Global Forwarding., DB Schenker Logistics., Panalpina World Tranport(Holding) Ltd., C.H. Robinson Worldwide, Inc., Hub Group, Inc./Unyson Logistics., Transplace.로 나타났다. 결과적으로 2007년, 2008년, 2009년 연도별 효율성이 점차로 감소되고 있으며, 비효율성이 원인으로 지목되는 규모의 효율성 개수가 점차로 감소하고 있음을 알 수 있다.

The core of this research studies the strategic alliance of airlines, container shipping liners, and port operators that have shown successful results through the recent differentiated strategic Alliance Network, although a difference of scale exists between these firms and the small and mid-sized International Logistics firms, but because of the worldwide traditional Alliance Network of International Logistics firms, HTFN's(High Tech Forwarder Network) half hearted attitude and the small scale alliance of the small and mid-sized International Logistics firms organized in 1998 cannot breakthrough the present strenuous situation. And these results, creating an attempt to save our country's International Logistics Industry which have fallen into depression, suggests an awakening of a new strategy based on specialized nationals innovative IT-which does not exist in the world market-by categorizing our country's small and mid-sized International Logistics firms which are active worldwide.

Economic globalization provides a good channel for the development of foreign trade around the world. Due to this background, this paper sets the Organization for Economic Co-operation and Development (OECD) countries as a sample to explore the importance of international logistics in foreign trade. An annual panel data from 2000 to 2017 will be used to conduct an empirical estimation under the panel unit root test and the fixed effect model. Foreign trade is treated as an explained variable and international logistics is treated as explanatory variables. The findings show that international logistics have a positive spillover effect on export trade and the speed of international logistics development has a regulatory effect on the relationship between both of them, which presents a U-shaped curve. When the speed of international logistics development is slow, an increase of it restrains the positive spillover effect of international logistics on export trade. However, when it rises to a certain extent, this increase releases the positive spillover effect of international logistics on export trade. As can be seen by the evidence that this paper provides, the impact of international logistics on foreign trade is dynamic. Moreover, this paper also puts forward some corresponding measures about the relationship between both of them.

In this paper, we propose a reference model for logistics processes to improve the effect of RosettaNet standards application to domestic industry. First of all, implementation cases applied to logistics processes in the world are investigated. Second, logistics processes of domestic manufacturers are analyzed for the application of RosettaNet standards, and the processes are compared with PIP. Finally, a new logistics processes model and corresponding PIP documents which reflect domestic situations are proposed.

The modem world has brought a wave of changes, not the least of which is globalization or what is often referred to as the "borderless society." In recent times, changes in the global business environment, such as trade deregulation and advances in technology, are challenging us to find new ways of thinking about and coping with these new forces. The field of global logistics has encountered a host of paradigm shifts as well. Therefore, it is critical that managers involved in international logistics take into account perceptional swift or at least understand the value of fully utilizing information. The appropriate management of human resources is a key factor in dealing with not only new information technology, but also shifts in the business environment. In particular, it will be important for Korea's logistics managers at international logistics companies to continually work to develop themselves, as they must carry out a critical role in global supply chain management. If they fail to take heed of the demand's of the new environment, the competitiveness of Korean enterprises in international logistics will suffer severely.

In the last few years growing interest has been dedicated to supply chain management. Modeling complexity is added to supply chain coordination problem by accounting for reverse logistics activities. The objective of this paper is to extend inventory model of manufacturing factory with respect to the production of raw material of forward logistics and recycling material of reverse logistics. The proposed model is applied to a plastic recycling process plant located in Taiwan. The case study improvement scheme shows when the recycling rate of recycling material increases from 15% to 50%, the total inventory cost of manufacturing factory decreases by 12.82%, safety stock volume decreases by 41.19% and the reorder quantity is down by 50.96%. This paper finds whether the results of the model can reach the economic profit through quantitative analysis and encourages companies integrate reverse logistics into the supply chain system.
