Incoterms is a standard transaction terms and conditions which is established to provide goods delivery, cost and risks between the seller and the buyer as a principle concerned. Incoterms is made of international rules about regular uses of transaction terms and condition. It removes uncertainty of misunderstanding and applying rules, commercial customs and etc, between nations. Incoterms does not have an enforcement like an unified rules or an agreements established between different nations. Therefore, it is just considered as a standard formal terms and conditions from International Chamber of Commerce. For those reasons, validity of Incoterms applies only when parties of contract come to an agreement not by officially adopted or applied by law in each nation. Incoterms 2010 contains specific and clear articles which is fixed version of incoterms 2000, it has insufficient points on insurance contract article. Though, insurance contract belongs to sales contract, it sustains independence itself. It is difficult to sustain perfection until establishment of insurance contract and expiration by fixing the articles. As a result, it is necessary for sellers and buyers take a full responsibility of making complete insurance contract. This paper is written for those reasons in this filed.

This paper is to review how Korean trading companies perform and promote the digital transformation through the e-networking with global market, and how much they extend the volume of export, and make the company grow inward or outward in order to enhance the effects of economic growth in Korea. It is suggested that global agreement on e-Trade(or u-Trade) should be made in order to expand the global e-networking practices and to ensure transferring of transport documents(or business documents). Moreover, it also suggested that networking on the global trading partners such as government authorities, diplomatic offices abroad, overseas Koreans, students studying abroad, Korean merchants abroad, etc. should be made in single window for improving and upgrading the image of Korean trading companies. By making of global e-network platform between overseas business partners, trading companies are able to expect various synergy effects such as improving the satisfaction of their customers, promoting the global transactions, reducing the operation and transaction cost, helping fording overseas buyers, and extending export volume and sales profit, etc. Customers can also obtain the information about trading goods easily and rapidly, and cut down the transaction stage using information exchange with partners. All of the trading partners in the world can maintain their business partnership as long as they use the global e-network.

As online shopping malls have emerged as a substantial shopping channel, they have used various sales promotion strategies to acquire new customers. Most of these strategies have been applied by offline malls for years. One, loss-leader pricing, is a type of promotional pricing in which stores sell well known products below their marginal cost, in order to attract customers and induce them to purchase more goods through impulse buying. This strategy is based on the expectation that customers will factor transaction costs into their purchasing decisions. However, its application to online malls fails to recognize that transaction costs are lower online, and that customers will behave differently as a result. Our study predicts that loss-leader pricing will not work online because online malls entail lower searching and moving costs than offline malls The study examines the effectiveness of loss-leader pricing with empirical data from a survey as well as log data from a Korean online shopping mall. The results show that while loss-leader pricing does attract customers to online shopping malls, it encourages cherry-picking rather than impulse purchases of regular-price goods.

Facing competitive and complicated business environment, many companies are developing new and diverse organization forms not only to overcome to minimize costs and risks but also to maximize the efficiency of an organization. Virtual organization is one of the representative forms allowing firms to create this value though a link of core competency among firms. In order to explain the performance of virtual organization in terms of efficiency, this study utilizes a concept of trust since it is recently considered as one of core concept to enhance the cooperative performance between firms and also virtual organizations success or failure can not be properly explained by traditional transaction-cost based economic point of view. Based on previous literature this study derives three success factors, organizational reputation, skill Uniqueness, and interpersonal trust and studies how three factors influence on the efficiency of virtual organization. Findings conducted with a questionnaire survey are as follow: first, organization reputation and skill uniqueness between virtual organization's transaction parties are important elements in the success of virtual organization. Second, interpersonal trust affected by organization reputation and skill uniqueness decides virtual organization's efficiency.

The explosive growth of the internet-based transactions requires not only a secure payment system but also an appropriate trust measuring methodology and secure transaction protocols to guarantee the minimal risk for the transacting entities involved in specific transactions. Especially, in internet auction systems where either buyers or sellers or both can be more than one in one transaction, providing those systems that make sure no one transacting entity takes a major risk becomes critical. In this paper, an improved trust measuring method using a relationship-based internet community for an auction system is proposed. The proposed system incorporates fuzzy set and calculation concepts to help build trust matrices and models, which is used to measure the level of risk involved in a specific auction trade concerned. Also, to optimize the auction trade process in terms of cost and time, the proposed system recommends a differentiated trade protocol according to the risk level involved in each auction trade. To test the appropriateness of the proposed trusted auction system, a prototype system has been developed under a Windows-NT environment.

This paper is to identify whether the mechanism of the real market as an off-line market developed from the transaction cost theory from previous research is applied to on-line market, such as usiness to Business e-marketplaces. With three factors(parties, product, environments) selected from previous research, four cases picked up from all B2B e-marketplace sites as of April 2007, in the view of Business to Business Matrix which presented by Kaplan & Sawhney(2000), were studied. They were accompanied by interview with CEO and team manager, and they explained their business and revenue model of the company. From the interview, the relation between three factors and usiness to Business e-marketplace was observed by taking sub-factors into consideration; parties -asset specificity, information asymmetry, product factors - standardization, price stability, and environments factors - competition, market uncertainty. The implications of this study are to analyze the relation of the transaction theory in offline and online. Also, this is the first study that analyzed it. In the future, another research based on this research will be studied.

L/C(Letter of Credit) is a common payment term designed to prevent credit risk in international trade. However, most companies prefer T/T (Telegraphic Transfer) payment due to its time and cost efficiency. According to related statistics, more than 70% of international trade contracts are based on T/T rather than other payment terms. The time required from the export negotiation to the completion of the export transaction and collection in international trade is very long. In this process, disputes related to settlement are continuous, so caution should be exercised. Therefore, whether or not the export payment is recovered in a timely manner is the core issue of trade transactions for exporters. The purpose of this study is to identify problems that cause delayed payments during settlement by the remittance (T/T) method, which can lead to settlement risk, in order to investigate those factors which can lead to delays in payments and increased risk as well as to determine ways to prevent such factors in advance. According to empirical findings, trading experience, transaction duration, and contract contents can be important determinants in terms of payment delays. Industry uniqueness and market uncertainty were found to be in opposition to the hypothesized relationships. The results of this study will be useful for trading companies to reduce their payment risk.

현재 블록체인을 기반한 공개형 암호화폐(이하 암호화폐)는 각국의 경제정책으로 거래를 위한 통화로써 지위를 얻을 수 없지만, 일부 인터넷 사용자들의 각자 사정으로 인해 대체 통화 거래수단으로 사용되고 있다. 이런 추세로 근미래에는 이러한 암호화폐가 인터넷을 넘어 실생활에서도 사용될 수 있을 것으로 생각되지만, 현재 인터넷 네트워크 인프라가 빈약한 곳에서 암호화폐가 실생활에 사용하기 어려워 이에 대한 대비책 마련이 필요하다. 본 논문에서는 실생활에서도 암호화폐 사용을 활성화하려는 방법으로 무선 인터넷 네트워크 인프라를 저비용으로 쉽게 구축할 수 있는 LoRaWAN을 기반으로 한 암호화폐 결제 시스템을 설계하기 위한 기술적 방법을 LoRaWAN 표준을 근거로 제시한다.

The widespread usage of blockchain technology in cryptocurrencies has led to the adoption of the blockchain concept in data storage management systems for secure and effective data storage and management. Several innovative studies have proposed solutions that integrate blockchain with distributed databases. In this article, we review current blockchain databases, then focus on two well-known blockchain databases-BigchainDB and FalconDB-to illustrate their architecture and design aspects in more detail. BigchainDB is a distributed database that integrates blockchain properties to enhance immutability and decentralization as well as a high transaction rate, low latency, and accurate queries. Its architecture consists of three layers: the transaction layer, consensus layer, and data model layer. FalconDB, on the other hand, is a shared database that allows multiple clients to collaborate on the database securely and efficiently, even if they have limited resources. It has two layers: the authentication layer and the consensus layer, which are used with client requests and results. Finally, a comparison is made between the two blockchain databases, revealing that they share some characteristics such as immutability, low latency, permission, horizontal scalability, decentralization, and the same consensus protocol. However, they vary in terms of database type, concurrency mechanism, replication model, cost, and the usage of smart contracts.
