The global demand for carbon neutrality in response to climate change is in a situation where it is necessary to prepare countermeasures for carbon trade barriers for some countries, including Korea, which is classified as an export-led economic structure and greenhouse gas exporter. Therefore, digital transformation, which is one of the predictable ways for the carbon-neutral transition model to be applied, should be introduced early. By applying digital technology to industrial gas manufacturing facilities used in one of the major industries, high-tech manufacturing industry, and hydrogen gas facilities, which are emerging as eco-friendly energy, abnormal detection, and diagnosis services are provided with cloud-based predictive diagnosis monitoring technology including operating knowledge. Here are the trends. Small and medium-sized companies that are in the blind spot of carbon-neutral implementation by confirming the direction of abnormal diagnosis predictive monitoring through optimization, augmented reality technology, IoT and AI knowledge inference, etc., rather than simply monitoring real-time facility status It can be seen that it is possible to disseminate technologies such as consensus knowledge in the engineering domain and predictive diagnostic monitoring that match the economic feasibility and efficiency of the technology. It is hoped that it will be used as a way to seek countermeasures against carbon emission trade barriers based on the highest level of ICT technology.

With the rapid spreading of the internet that is based on the development of the information network system, the paradigms of "internet round" and "cyber" are given much weight in the notion of "market." Especially, the cyber shopping for the individuals is developing rapidly creating the new life style, and also in the domestic economy the cases of building and running the cyber shopping malls are increasing. The purpose of this study is to analyse the customers' shopping styles that can be shown when the customers purchase physical goods or digital goods at the B to C EC and find the way to activate the shopping malls by controlling the factors which influence the trade. The result of the study is as follows: First, to analyse the acting style of the customers at the B to C EC, it is searched whether there is any relationship between the purchasing goods, which are divided into physical goods and digital goods. There was a cross analysis between the first factor of the five factors of the purchase decision or delay at the B to C EC and the goods type. The result of the analysis is that the purchase decision factor is different according as what type of goods is purchased. On the other hand, the purchase delay factor has no relation with the goods type. Second, the fact that the cyber shopping activities are quite different according to sexuality, age, academic background, or occupation suggests that these factors are very important to the strategy for the market-specification of the B to C EC marketing construction. The result shown in this study is sure to give great help to figure out the improvement strategies and the market-specialization strategies to accelerate the B to C EC marketing. On the side of the strategies for the improvement of the goods services, more attention should be given to the functional side for the improvement of the reliability of the goods service such as capacity, technique, and quality. And the activities of the customers are so different according to the vital statistics that the way to cope with the changeability properly should be considered.

As exhibition industry, which is a part of 17 new growth engines of the government, is related to other industries such as tourism, transportation and financial industries. So it has a significant ripple effect on other industries. Exhibition is a knowledge-intensive, eco-friendly and high value-added Industry. Over 13,000 exhibitions are held every year around the world which contributes to getting foreign currency. Exhibition industry is closely related with culture and tourism and could be utilized as local and national development strategies and improve national brand image as well. Many countries try various efforts to invigorate exhibition industry by arranging related laws and support system. In Korea, more than 200 exhibitions are being held every year, but only 2~3 exhibitions are hosted with over 400 exhibitors and except these exhibitions most exhibitions have few foreign exhibitors. The main reason of weakness of domestic trade show is that there are no agencies managing exhibitionrelated statistics and there is no specific and reliable evaluation. This might cause impossibility of providing buyer or seller with reliable data, poor growth of exhibitions in terms of quality and thus service quality of trade shows cannot be improved. Hosting a lot of visitors (Public/Buyer/Exhibitor) is very crucial to the development of domestic exhibition industry. In order to attract many visitors, service quality of exhibition and visitor's satisfaction should be enhanced. For this purpose, a variety of real-time customized services through digital media and the services for creating new customers and retaining existing customers should be provided. In addition, by providing visitors with personalized information services they could manage their time and space efficiently avoiding the complexity of exhibition space. Exhibition industry can have competitiveness and industrial foundation through building up exhibition-related statistics, creating new information and enhancing research ability. Therefore, this paper deals with customized service with visitor's smart-phone at the exhibition space and designing mobile framework which enables exhibition devices to interact with other devices. Mobile server framework is composed of three different systems; multi-server interaction, server, client, display device. By making knowledge pool of exhibition environment, the accumulated data for each visitor can be provided as personalized service. In addition, based on the reaction of visitors each of all information is utilized as customized information and so the cyclic chain structure is designed. Multiple interaction server is designed to have functions of event handling, interaction process between exhibition device and visitor's smart-phone and data management. Client is an application processed by visitor's smart-phone and could be driven on a variety of platforms. Client functions as interface representing customized service for individual visitors and event input and output for simultaneous participation. Exhibition device consists of display system to show visitors contents and information, interaction input-output system to receive event from visitors and input toward action and finally the control system to connect above two systems. The proposed mobile framework in this paper provides individual visitors with customized and active services using their information profile and advanced Knowledge. In addition, user participation service is suggested as well by using interaction connection system between server, client, and exhibition devices. Suggested mobile framework is a technology which could be applied to culture industry such as performance, show and exhibition. Thus, this builds up the foundation to improve visitor's participation in exhibition and bring about development of exhibition industry by raising visitor's interest.

This research aims to review every important academic research on risk management in FTA and to suggest a future area for further research. This research area seems to focus on conceptual study or fact finding rather than on theory development or empirical research on causal relationship or theory testing. The National Assembly Digital Library analyzed the results of 3,576 researches on thesis and journals fromthe results of the FTA. Research on FTA is analyzed in four major themes. First, there have been previous studies on business performance such as FTA export performance and economic effect. Second, analyzed the effects of FTA in product and service. The products are classified into agricultural, marine products, manufacturing, textiles and clothing, medicinal pharmaceuticals, cosmetics, and others. Services are classified into educational and cultural contents, service industry and financial industry. Third, research on the risk management of FTA Origin is broadly classified into the use of country of origin and the verification of origin, and the use of origin includes the study of rules of origin and systems of origin and management. Origin verification was divided into origin verification and origin risk management. Fourth, study on the conclusion area of the FTA, studies were conducted on areas such as Korea-US FTA, Korea-China FTA, Korea-EU FTA, Korea-Japan FTA, Korea-Chile FTA, and Korea-ASEAN FTA. Search results through the FTA, focused on analyzing the FTA area and concept research by research purpose. In addition, research methods are mainly focused on documentary survey, and research areas are concentrated on specific countries such as China and USA. This implies a necessity for a future development in that research area. Other areas for future research may include case research on actual failures in FTA, proactive risk management strategy, and integrated risk management for export companies. Risk management in FTA may help investment expansion, and that is why research on the issue matters.

Advances in information technology, communication and network technology are radically facilitating digital convergences as the integration of human, equipment, and space in the current industry 4.0 era. In industry 4.0 environment, the vast amount of information with networked computing technology can be simultaneously accessible even in limited physical space. Two main benefit points out of these information are the convenience and efficiency in their online transactions either buying things online or selling online. Even though there exist so many benefits that information technology can create for the people doing business over the internet there is a critical problem to be answered. In spite of many such advantages, however, online transactions have many dysfunctions such as personal information leakage, account hacking, and cybercrime. Without preparing the appropriate protection methods or schema people reluctantly use the transaction or would find some other partners with enhanced information security environment. In this paper we suggested a novel selection criteria that can be used to evaluate the reliable means of authentication against the expected risks under on-going IoT based environment. Our selection criteria consists of 4 steps. The first step is services and risk identification step. The second step is evaluation of risk occurrence step. The third step includes the evaluation of the extent of damage. And the final step is the assessment of the level of risk. With the help of the above 4 step-approach people can systematically identify potential risks hiding in the online transactions and effectively avoid by taking appropriate counter actions.

In this paper, we present an NFT auction service for the next generation, named NextAuction, which can reliably trade ownership of individual content using DID technology. Recently, as the types and sizes of tradable digital assets have expanded, the number of NFT transactions has also increased, and a significant number of marketplaces are being operated. But, the current user authentication methods of NFT marketplaces are done only through the associated blockchain wallets. It is desirable that ownership transfer through NFT transactions be transparently managed based on a more reliable identity authentication service. NextAuction increases the reliability of auction service participants by transparently and consistently providing identity authentication for users of auction services based on the DID technique using the Klaytn blockchain. In addition, in preparation for server failure that may occur during the auction of individual content, it provides users with a robust auction service using the BR2K technique that continuously provides consistent service through the replication of a target service. The NextAuction service is developed by extending BCON, a blockchain-based content management service.
