Thanks to information technologies, sharing economy services offer a new way of consumption. Carsharing appeared as a novel type of service that transformed the conventional way of personal transportation, from owning a vehicle to using an on-demand service. Allowing users to use a vehicle without owning a car, carsharing provides various social benefits such as the reduction of resource allocation inefficiencies and the alleviation of transportation problems. To strengthen such positive aspects of carsharing service, it is essential to understand an individual's service usage pattern and reveal factors that affect users' reuse behavior. This study investigates the factors that have an influence on carsharing reuse of users applying RFMC (Recency, Frequency, Monetary, and Clumpiness) model, the popular model for understanding the reuse likelihood of customers. Using data from a leading carsharing service provider in South Korea, we empirically analyze the effect of RFMC on carsharing reuse behavior. The findings show that recency and monetary values are negatively related to reuse while frequency is positively related to carsharing service reuse. Moreover, the impact of recency and monetary value are more salient whereas the impact of frequency is smaller among users with higher clumpiness. Based on these findings, this study elaborates on theoretical and practical implications.

For Airbnb, one of the most successful examples of the sharing economy, to continuously grow, it needs a steady supply of attractive listings. To this end, this study draws on existing research on Airbnb and signaling theory to examine the factors that influence the performance of Airbnb listings. From a dynamic perspective, we expect the importance of factors affecting listings' performance to differ between new and existing listings. Analyzing Airbnb data from the 10 most active US cities using negative binomial regression, we find that dynamic attributes that require a time investment have a stronger impact on existing listings, while static attributes that require less of a time investment have a similar effect on both types. The host's membership duration and number of listings were expected to have positive effects, but showed negative effects. While the instant booking policy increased users' convenience, some hosts were reluctant to use it. The results of the analysis suggest that the importance of the factors varies depending on the type of Airbnb listing (new vs. existing), and the need for differentiated policies and complementary measures based on the type of listing is necessary in a practical perspective.

In these days, people get information from internet easily. However, there are too many information. It makes interrupt and inefficient for searching data. Therefore, we need user customized web search system which provides appropriate information. In this paper, we propose a searching system that can collect semi-automatically conditions of users such as weather, location and time and provide essential information to users. Using these context data, the proposed system can understand what information users want in specific situations and can provide more useful information to users than existing systems. The proposed system based on 'Production/Sharing Service of Personal Korean Contents with Voluntary Sharing Economy System' and we add data parsing algorithm in each input, store and search part. In the experiments, we compare and analyze the results of existing system and the proposed system using some general key words.

Collaborative consumption was suggested as a new paradigm of consumption and business model that focuses on sharing and using resources to reduce the risks of resource depletion and environmental impact. Individual consumers carry out a role not only as users but also as providers for collaborative consumption. In the present study, the authors investigated consumers' intention to participate in collaborative consumption both as providers and users. The effects of perceived benefit of collaborative consumption, subjective norms and ease of participation on the intention to participate in collaborative consumption were analyzed. The perceptions on benefits and subjective norms were relatively high, while the perception on ease of participation was relatively low. The effects of subjective norms and ease of participation on the intention to participate in collaborative consumption were significant. The result shows that support from one's reference group and the perception on ease of participation have significant positive effects on the intent to participate in collaborative consumption. Therefore, communication strategies for developing a positive consumer attitude and a social consensus about the necessity of collaborative consumption are needed.

Countries around the world have been engaging in automatic exchange of information to tackle tax evasion. The same goal became the basis of the enactment of the Foreign Account Tax Compliance Act (FATCA) by the United States Congress. In order to establish a common approach to counter tax evasion among different countries, the Organization of Economic Cooperation and Development (OECD) released the Standard for Automatic Exchange of Financial Account Information in Tax Matters which consists of the Competent Authority Agreement (CAA) and the Common Reporting Standard (CRS). Specifically, the automatic exchange of information is the exchange of financial account information between Tax Authorities in relevant countries. The law requires this information to be collected by financial institutions around the world for reporting to Tax Authorities. Automatic exchange of Information is made up of two information sharing frameworks: The Foreign Account Tax Compliance Act (FATCA) and The Common Reporting Standard (CRS). Under the automatic exchange of information, all financial institutions must identify accounts held by customers who are foreign tax residents or entities connected to foreign tax residents. Financial institutions must report these to the relevant Tax Authority who will then automatically exchange the account information with the relevant foreign Tax Authorities. Korean government has enacted domestic laws to require financial institutions to collect and report this information and has entered into international agreements to exchange the information with other governments. This paper analyzed the FATCA and CRS rules overall and proposed solutions for the legal and practical issues. This paper contributes to the existing literature on the automatic exchange of information by considering two information sharing frameworks.

With the growth of the global sharing economy market, various sharing services have recently appeared in South Korea. Seoul city unmanned public bicycle rental service, "Ttareuni" is one of the services representing the shared mobility industry in South Korea. Although many users use this service, the usability of the mobile application, which is the essential medium of utilizing the service, is not improving. In this regard, this study conducted usability testing and in-depth interviews for Ttareungi's main users in their 20s and 30s to improve the user experience of the mobile application of Ttareungi. As a result, the problems of Ttareungi mobile application were identified, and based on this, design considerations for shared mobility services having publicity like Ttareungi were proposed. This is expected to contribute to improving the user experience of shared mobility services.

In recent decades, China's economy has grown rapidly and two-dimensional bar code-based payments services have been activated. This is a model that will be introduced by developing countries that lack mobile payment infrastructure, and countries that are looking to leap into cashless societies are also drawing attention. Along with this, the existing CRM market is expanding around the mobile device called m-CRM, and research is active on the importance of collective use for online advertising and two-dimensional bar code-based payments services. Therefore, through this study, we have explored the concepts and status of online advertising and customer relationship management which using the two-dimensional bar code-based system, and designed and implemented the method and mobile application system to effectively disseminate transactional advertising information at the point of sale or at the point of share. We also presented an application approach to look at the direction of two-dimensional bar code-based ads contents sharing system and its development.

he purpose of this study is to propose a shared platform service that can deal with used books based on small stores. The volume of used book market has more than doubled since the book price system, and large bookstores are actively participating in the used book market. Used book sharing platform is an advanced form of online used book direct trade and can be easily used by installing applications on the user's mobile phone. The second-hand book sharing platform is not a shared platform that creates a huge profit-making enterprise, but a future-oriented shared platform that can benefit all users of the platform. If the shared platform, which is the core of the fourth industrial revolution, is applied to almost all small stores and utilized as a hub for second-hand book transactions, it will establish itself as a more reasonable market for second-hand book transactions.

Recently, demand for technology for energy economy and stable supply is increasing due to the increase in power demand of loads. The amount of DC power generation using new and renewable energy is noticeably increasing, and the use of DC power supplies is also increasing due to the increase in electric vehicles and digital loads. During parallel operation to increase the capacity of the power converter, the module bus method or the method using Can communication and serial communication has significant difficulties in smooth operation due to communication time delay for information sharing. Synchronization of information sharing of each power converter is essential for smooth parallel operation, and minimization of communication time delay is urgently needed as a way to overcome this problem. In this paper, a new communication method using pulse width information is proposed as a communication method specialized for parallel operation of power converters to compensate for the disadvantage of communication transmission delay in the existing system. The proposed communication method has the advantage of being easily implemented using the PWM and Capture function of the microcomputer. In addition, the DC/DC converter for DC distribution was verified through simulation and experiment, and it has the advantage of easy capacity expansion when applied to parallel operation of various types of power converters as well as DC/DC converters.

Since July 7 mutual declaration in 1988 which is a landmark for South-North Korean relations, Inter-Korean Trade has been set out. During the period, the Inter-Korean Trade has been ups and downs depending on the Inter-Korean relations and economic situation of both countries. South Korea became one of the major three trading countries of North Korea's trading partners in 2000, when the sum of annual trade volume reached the record 425million US dollars. A rapidly increasing number of countries including North Korea are developing national policies and strategies to promote the digital economy, recognizing the potential benefits of e-business as an engine of growth and development. However, the trade structure of South-North Korea remains very simple in terms of its contents. Furthermore trade procedure many limitations especially electronic commerce in North Korea has many obstacles to working properly. The information in Inter-Korean trade cannot be shared in common. South Korean firms have suffered repeatedly trial and error and excessive competition took place among South Korean firms. Institutional inertia related to mutual trade, political and military Impacts on Inter-Korean economic relations, abnormal industrial structure of North Korea and insufficiency of SOC could be mentioned as major problems in Inter-Korean trade as well. Several measures should be taken in order to cope with those problems. First of all, South Korean government should provide valuable information to business firms about North Korean economy and business environments. It is suggested that forums related to inter-Korean trade hold in regular base between South and North Koreas and establish the system of business information sharing. Second, the government should improve various laws and regulations to respond to the realistic needs of inter-Korean trade. That is, detailed measures should be taken to guarantee investment in electronic commerce. Third, it is desirable to start with the mutual agreement between South and North Korea.
