The purpose of this paper is to clarify the prospects and problems in the study of geography related to the concept of commodity, transport, and supply chains. The geography studies related to commodity chains are expanded to each field of industry focusing on the subjects and economic difference which lead the commodity chain in core and periphery regions. These vertical connection are studied with the political economy approach that gives attention to geographical pattern of agricultural products and foods. But in viewpoint of commodity circuit and commodity network, the culture or subjects of micro regions and interaction are also studied. The contents of these study are to clarify the importance of cultural turn and local. And the study of chain standpoint appears that the series of transport process by transportation modes can be understood by transport chains and the physical distribution process of sea freight is to be grasped by supply chains.

In recent years, as there is growing concern with ESG (Environmental, Social, and Governance), the strategic direction of business management is changing from maximizing shareholders wealth to maximizing stakeholders value. ESG is reshaping a corporation's supply chain management strategies. The purpose of this study is to explore the ESG challenges in supply chain management. As a result of network text analysis and topic modeling analysis on 3226 news articles, 'Suppliers', 'Sustainability', 'Shared Growth' 'Carbon Neutral', 'Safety and Health', 'Responsible Business Alliance', 'Supply Chain Due Diligence Law' were identified as the main issue. Since ESG initiatives in the supply chain are not limited to the efforts of individual firms, future research should focus on figuring out what difficulties and challenges exist in the diffusion of ESG practices along multi-tiered supply chains, and how to overcome them.

We introduce about XBRL, eXtensible Business Reporting Language, which is widely accepted as the international standard language for business financial reporting. XBRL is a language for the electronic communication of business and financial data which is revolutionizing business reporting around the world. It provides major benefits in the preparation, analysis and communication of business information. It offers cost savings, greater efficiency and improved accuracy and reliability to all those involved in supplying or using financial data. XBRL is a kind of XML application based on the open Internet technologies. We propose a framework for enterprise information supply chain using XBRL Web services. A Web service is defined as a software system based on XML and designed to support interoperable machine-to-machine interaction over a network by the W3C. Web services are frequently just application programming interfaces (API) that can be accessed over a network, such as the internet and executed on a remote system hosting the requested services. An XBRL Web service-based enterprise information supply chain enables for companies to implement seamless information supply chains from businesses to financial institutions, to supervisory authorities, and to other stake holders for real time information access. And thereby it is expected to contribute to the increase in the value of companies due to the enhanced visibility and transparency of accounting and management.

On account of multiple causes, including prolonged global economic crisis, addressing environmental pollution and the advent of hyper-connected society, a new paradigm called 'sharing economy' has rapidly emerged. Many startups have attempted to build promising business model based on the sharing economy concept. Nevertheless, successful cases are still very rare in the global level, except for Uber and Airbnb cases. Therefore, this study analyzes necessary causes and sufficient causes for successful settlements in the market through a comparative case analysis on digital matching firms in the sharing economy businesses. For the case study, we compare five successful cases (Uber, Airbnb, Kickstarter, TaskRabbit and DogVacay), three failure cases (Homejoy, Ridejoy and Tuterspree) and a platform cooperativism case (Juno) in accordance with six value attributes of business model including value proposition, market segment, value chain, cost structure and profit potential, value network and competitive strategy. We apply Boolean method to support controlled comparison and eliminate unnecessary attributes. The Boolean analysis result shows that value proposition, cost structure and profit potential, value network and competitive strategy are the essential attributes. Furthermore, the result indicates that each attribute is a necessary condition, where all four conditions should be met simultaneously in order to be successful. With this result, we discuss essential consideration for those who are planning startup based on the sharing economy business model.

The EPCglobal Network is a computer network used to share product data among trading partners. It provides the supply chain with improved visibility and traceability by using Electronic Product Code (EPC), which is stored on an RFID tag. Although this network model is widely accepted as a global standard and the growth of EPCglobal-subscriber base is considerable, the EPC technology adoption process is still in its infancy. This is because some of the critical issues on this model still remain to be verified such as scalability, data management, security, privacy and the economic value of data sharing. In this paper, we focus on scalability issue among the challenges to overcome and we regard performance of the EPCglobal Network only as a track and trace query-processing cost in the network. We developed performance models consisting of three elements of the EPCglobal Network : Discovery Services (DS), EPC Information Services (EPCIS), Object Naming Services (ONS). Then we abstracted out the track and trace query execution model to evaluate performance of the overall EPCglobal Network. Finally using the proposed models, we carried out simulation analysis based on an RFID-based inbound logistics process of automobile parts. This work is an important step towards the EPC technology diffusion and provides guidelines for businesses looking to buy or build the EPCglobal Network-based systems.

Supply chain in service sector has been established on the premise that firms need to manage their process uncertainties to satisfy customers in an efficient manner. Information sharing and synchronization play key roles in minimize uncertainties from their involved supply chain. The duality of customers being inputs providers as well as consumers, differentiates service supply chains from manufacturing and is a challenging issue to traditional supply chain management. The service supply chain is a structured network which should be managed with supply chain theory and principles. Various key operations need to be carried out through a highly integrated and collaborated service supply chain and supporting information hub. The purpose of this paper is to present the issues and key components in the service supply chain, where the repetitive service is provided along the value chain, such as tourism, restaurant, mega-sized hospital supply chain.

It is difficult to found the concept of public interest properly, being ambiguous to distinguish media and service as to the convergence of broadcasting and telecommunications. Accordingly, it is necessary to found the concept of public interest not related to the character of media and service in the age of digital convergence. Therefore this study intended to re-found the concept of public interest, as to industrial changes in the age of convergence of broadcasting and telecommunications. The convergence of broadcasting and telecommunications causes the changes of value chain, which includes contents, platform, network, terminal. It could not help avoiding modifying the industrial structure of broadcasting and telecommunications, because of the changes of value chain. The changes of industrial structure needs the changes of ideology, regulatory policy, regulatory system, and it creates the foundation of new regulatory idea. The purpose of regulatory idea in the age of digital convergence is to practice public interest, and it is an ultimate purpose to increase consumers' welfare. Consequently, for increasing comsumer' welfare, it is necessary to achieve diversity, fairness, objectivity, the preservation of social value in the aspect of contents. Also in the aspect of platform, it is necessary to achieve the protection of privacy, consumer protection, harmful information blocking, and in the aspect of network, it is necessary to achieve the maintenance of secure network, fair competition. Finally, in the aspect of terminal, it is necessary to achieve the maintenance of compatibility, the solution for digital divide. Then regulatory policy of each value chain from a legal and institutional perspective, should be promoted to provide public interest, step by step.

Strategies for regional development has been implemented by facilitating the cultural industry since the mid 1990s. The government of Gyeongbuk attempted to establish the cluster of cultural industries and to enhance the capability of cultural industries. However, infrastructure of the industries is still weak. The most cultural industries are small-sized enterprises and are in low value-added production link in the value chain. This research examines the situation of cultural industries and then to recommend the direction of cluster of cultural industries in Gyeongbuk. The cluster of cultural industries in Gyeongbuk needs to be decentralized integration. Cultural industries in Gyeongbuk are found in dispersed regions with own cultural and industrial characteristics. The hub of cluster of cultural industries should be formulated to promote network among cultural industrial complexes in dispersed regions; thus, the hub is able to provide knowledge and information for the cultural industrial firms in Gyeongbuk. The supporting center as the hub of cluster has to input more energy to establish the on-line and off-line network among firms, and between firms and innovation agencies such as universities, cultural industrial organizations, and local governments. The cultural industrial cluster should be linked with IT cluster in Gumi and cluster of Daegu cultural industries to upgrade the value chain of cultural industries.
