Metaverse is a digitally generated world beyond the physical realm; many fashion brands are launching virtual stores in Metaverse. This study explores the cases of flagship stores of fashion brands in Metaverse to understand the peculiarity of Metaverse retailing. This study selected four flagship stores of fashion brands launched on ZEPETO, the largest Metaverse platform in Korea. The characteristics of Metaverse retailing used for case analysis were store (store credibility, servicescape, ease of use), product (content, demos, incentives), social factor (store personnel, store customers), and entertainment (events, games, free gifts). The results illustrate that a transaction system linked to reality could not be established due to technical limitations; it was difficult to obtain specific product information, such as the color, size, and fabric. However, all four fashion brands overwhelmed the traditional retail channels in terms of providing various spatial experiences by operating their virtual stores in global cities related to the heritage and identity of each brand. Furthermore, fashion brands can convey a sense of deviation and fantasy to consumers by delivering unique entertainment activities in Metaverse that they cannot easily provide in real life.

The purpose of this study was to analyze the effect of service factors of used book transactions, which are becoming a major service in online bookstores, on customer satisfaction and the effect of customer satisfaction on reuse intention. 235 samples were collected through a survey for users of used book transaction services in their 20s or older, and 205 surveys were adopted through the refining process. Hypotheses were verified through factor analysis, reliability analysis, and structural model analysis using SPSS22.0 and AMOS22.0 statistical programs. Some factors were supported between service factors and customer satisfaction, and customer satisfaction had a significant effect on reuse intention, and moderating effects according to the preferred genre of reading were founded. More differentiated services should be considered according to the customer's preferred genre, as the services of online bookstores are becoming more standardized, customers do not feel differentiated.

With the recent rise of blockchain technology, cryptocurrency platforms using it are increasing, and currency transactions are being actively conducted. However, crimes that abuse the characteristics of cryptocurrency are also increasing, which is a problem. In particular, phishing scams account for more than a majority of Ethereum cybercrime and are considered a major security threat. Therefore, effective phishing scams detection methods are urgently needed. However, it is difficult to provide sufficient data for supervised learning due to the problem of data imbalance caused by the lack of phishing addresses labeled in the Ethereum participating account address. To address this, this paper proposes a phishing scams detection method that uses both Trans2vec, an effective graph embedding techique considering Ethereum transaction networks, and semi-supervised learning model Tri-training to make the most of not only labeled data but also unlabeled data.

Smart Farm means creating new value in various fields related to agriculture, including not only agricultural production but also distribution and consumption through the convergence of agriculture and ICT. In Korea, a rental smart farm is created to spread smart agriculture, and a smart farm big data platform is established to promote data collection and utilization. It is pushing for digital transformation of agricultural products distribution from production areas to consumption areas, such as expanding smart APCs, operating online exchanges, and digitizing wholesale market transaction information. As such, although agricultural data is generated according to characteristics from various sources, it is only used as a service using statistics and standardized data. This is because there are limitations due to distributed data collection from agriculture to production, distribution, and consumption, and it is difficult to collect and process various types of data from various sources. Therefore, in this paper, we analyze the current state of domestic agricultural data collection and sharing for digital agriculture and propose a data collection and linkage method for artificial intelligence services. And, using the proposed data, we propose a deep learning-based environmental factor recommendation method.

The platform concept has been used for business operations in various forms: product platforms, transaction platforms and industry platforms. All these platforms have common characteristics of having 'core' that is reused frequently and 'peripherals' that are less reusable and changed often. Companies use platforms to enable efficient development and creation of product family, transactions and innovation. These platforms provide new opportunities for many small and medium-sized companies (SMEs) by bringing changes to traditional industrial structures focused on the products rather than platforms. The service robotics industry in South Korea is mainly composed of technology-intensive SMEs due to its small market size. Although these SMEs succeed in developing technologies, they have difficulties creating and expanding markets to sell products. Thus, this study addresses the characteristics and problems of the South Korean service robotics industry and analyses how ROBOPRINT, one of the SMEs in the service robotics industry, successfully creates and continuously expands the service robot market by adopting platform concept. The results indicate that ROBOPRINT has been applying two types of platforms: product and transaction platforms. First, ROBOPRINT created art robots that were apartment mural service robots. Rather than selling art robots, the company developed various robots such as painting robots, building exterior wall-cleaning robots by reusing the core technology of the robots. The company also developed various robots according to the buyers request. In addition, the company used the robots to directly provide apartment mural services for customers. This mural service has been extended into various areas, not only in apartments but also in soundproof walls, underground passages, and retaining walls. Besides, ROBOPRINT added new services continuously by developing technologies such as virtual reality. Second, ROBOPRINT mediated mural service buyers and mural designers. This platform reduced buyers' workload, which necessitates requesting mural services to ROBOPRINT and searching for mural designers. For designers, this opened up new opportunities to participate in the mural business. The platform attracted both mural buyers and designers who were scattered before. Finally, ROBOPRINT seeks to expand the platform's scope to outside company. To share internally reused ROBOPRINT's technology with other companies, the company participated in Daegu city's 'New Technology Platform Industry'. Furthermore, ROBOPRINT is trying to share the service platform by leasing robots to other companies. This allows external agents to develop technologies and provide services by reusing resources from ROBOPRINT. This study contributes to existing theories by showing that SMEs continuously create and expand markets by building various platforms. Moreover, it provides useful implications for practitioners by describing the firm's specific platform-building strategy.

The housing market is changing continuously according to the place and time and these changes have a ripple effect across various fields. On the other hand, the amount of housing that is consumed in the region also acts as a central cause of price movement. Moreover, the cause of variations in the housing market can be separated according to the characteristics of the housing consumer. In addition, the individual characteristics of the consumer varies according to the region. As a result, a study on the regional causal relationship of the housing market is underway. Although significant research has been done on the domestic home sales market, there has been limited research on the housing charter market. Therefore, in this paper, regional causal relationship of the housing market in the Gangnam and Gangbuk area in Seoul and Gyeonggi Province was analyzed using the vector error correction model, and is segmented by housing sale market and housing jeonse market. In addition, housing sale and housing jeonse of Gangam, Ganbuk and Gyeonggi province are defined as analysis variables, and time series data is the monthly material of June 2003 to November 2015. The results of the analysis, in the case of the housing sale market, showed that fluctuations in house prices in Gangnam area have a major influence on the fluctuations in house prices in the surrounding region. Similarly, in the case of the housing jeonse market, it was found that the jeonse price of Gangnam area has a significant impact on the jeonse price of housing in the surrounding area.

This study is based upon the assumption that trust is a pedestal of much importance in the relationship behavior marketing channel members conduct in their arena. Unlike the existing studies that consider trust to be a circular simple concept with the emphasis on mutually symmetrical relationship level, this study focuses on the asymmetrically different levels of asymmetric trust concept. The major results of this study are as follows: First, among the individual characteristics which could affect on trust, reputation plays a significant role in transaction. Second, in the domain of the relation between trust and relationship characteristics, opportunistic behavior is shown to influence upon trust. Communication is turn out not to be a significant factor in trust; in a further analysis, it is also shown to influence upon willingness to make future relationship behavior. Third, willingness to make future relationship behavior plays a significant influence on trust, which shows that trust is the very core factor in the long-term relationship behavior. We can find that the antecedent factors influencing upon the trust build-up are different between agents and buyers and the established trust influences upon the future relationship behavior. This study tries to show how trust is established and what role the trust conducts.

This study is to clarify regional structure and connection of international physical distribution through clearance depot of Cheongju customs of inland location. The trade of clearance depot of Cheongju customs industrial characteristics reflects of territorial hinterland. As origins and destinations of freight as exports and imports region, territories of Cheongju customs trade mainly with Japan, China, and USA. Origin and destination of freight of Cheongju customs territory are hinterland and foreland of Incheon International Airport and Busan port. In case of export, foreland of Busan port is board, and in case of import, the hinterlands of Incheon International Airport and Busan port are similar. Clearance depot of inland-located Cheongju is construct by the advantages of rapidness and inexpensive cost. And the kind of freight and system of physical distribution of each enterprise show different characteristics. For each export and import freight, each shipper corporation has its own physical distribution system, and structure of international distribution is classified into export pattern of bonded industry and bonded warehouse. Again the patterns of bonded warehouse are distinguished free on board price system with division of labor in base of production in overseas, free on board price system, and cost-insurance-freight with division of labor in base of production in overseas. These Phenomena are caused by transaction between headquarter and its overseas corporation, initiative freight handling of export corporation, choice of inexpensive cost, and international convention.
