The purpose of this paper is to suggest strategies for Korean companies to overcome the limitation of the international trade structure between Korea and Vietnam. This study examined foreign multinational distribution companies, Korean distribution companies and domestic distribution companies in Vietnam. A SWOT analysis conducted to propose effective strategies revealed that Saigon Mart, Vietnam's largest regional mart company, needs an O/W strategy and to capture market opportunities quickly through strategic alliances with foreign distribution companies, in order to gradually complement their core competencies internally. Lotte mart in Vietnam, one of Korea's three largest marts, needs to establish a T/S strategy in order to overcome the crisis situation in Vietnam market and succeed in business. BIG C Mart has over 40,000 diverse products needs to use a T/S strategy in order to effectively overcome the crisis situation in the Vietnamese market and to increase the possibility of business success. From the study findings and conclusions, various implications are derived. Vietnam is still very strong in socialism and regional characteristics, so it needs to build up close cooperation such as joint venture with local partners in the region and strategic alliances to increase the possibility of investment success.

전자상거래의 활성화에 따라 이동매체의 안전에 대한 요구사항이 늘어나고 있다. 이동매체간의 호환성을 제공하기 위해서는 보안 API(Application Programming Interface)가 쉽고 안전하게 설계되어져야한다. 현재 많은 제품과 개발에 호환성과 확장성 표준을 제시하고 있는 RSA사의 PKCS(Public Key Cryptographic Standard) #11 인터페이스를 선택하여, 국내 전자서명 표준인 KCDSA(Korean Certificate-based Digital Signature Algorithm) 메커니즘을 제공하고자 한다. 그리고, PKCS #11 보안 API에 새로운 키 관리 함수를 정의하므로써 보다 더 안전한 키 관리 기능도 지원한다. KCDSA 개인키와 공개키의 객체 속성과 템플릿을 정의하고, KCDSA 메커니즘으로 전자서명을 생성하고 검증할 수 있도록 한다. KCDSA 메커니즘을 제공하는 PKCS #11을 설계 및 구현하여 성능평가하고, 보안성 및 호환성에 대하여 비교분석한다.

Internet users are increasingly invited to express their opinions on various subjects in social networks, e-commerce sites, news sites, forums, etc. Much of this information, which describes feelings, becomes the subject of study in several areas of research such as: "Sensing opinions and analyzing feelings". It is the process of identifying the polarity of the feelings held in the opinions found in the interactions of Internet users on the web and classifying them as positive, negative, or neutral. In this article, we suggest the implementation of a sentiment analysis tool that has the role of detecting the polarity of opinions from people about COVID-19 extracted from social media (tweeter) in the Arabic language and to know the impact of the pre-processing phase on the opinions classification. The results show gaps in this area of research, first of all, the lack of resources when collecting data. Second, Arabic language is more complexes in pre-processing step, especially the dialects in the pre-treatment phase. But ultimately the results obtained are promising.

I explore that South Korea's major import fishery product markets-frozen hairtail, frozen mackerel, frozen pollock and frozen squid-are integrated by testing whether there is favorable evidence of the law of one price (LOP). Unlike previous studies on the LOP for fishery product markets, I assume non-zero import costs and include them in a trade model. To explore whether LOP holds for major import fishery product markets in South Korea with non-zero import costs, I utilize a non-linear time-series model, Smooth Transition Autoregressive (STAR) model with the sample periods from January in 2002 to December in 2019. I find that the behaviors of home-foreign price (i.e., import price) differentials of all four major import fishery products are non-linear depending on whether trade occurs and favorable evidence of LOP for each import market in South Korea. These findings indicate that each of South Korea's major import fishery product markets is integrated. They imply that the supply of each major import fishery product-frozen hairtail, frozen pollock, frozen mackerel and frozen squid, and their prices are stable even if there is an economic shock on each market. When it comes to trade policy implications, the Korean trade policy including tariffs or quotas against their import countries for the four major import fishery products may not have influences on their price in the markets.

Purpose - Using trade data from 2008 to 2019, this study analyzes the impact of trade facilitation on China's agricultural exports under the RCEP framework using a gravity model based on the level of trade facilitation in 13 RCEP countries. Design/methodology - This study constructs a complete set of trade facilitation index systems, comprehensively measures the trade facilitation level of RCEP member countries, and uses a gravity model to verify the critical role of trade facilitation level in enhancing the trade volumes of RCEP member countries. Findings - We found that trade facilitation has a significant impact on China's agricultural exports as a whole. The effect of each primary indicator varies in magnitude, with finance and e-commerce (F) having the most significant impact, followed by customs efficiency (C) and infrastructure development (1); the institutional environment has no significant effect. Originality/value - This study analyzes the impact of trade facilitation on China's agricultural exports from the perspective of exports, and uses the latest data to study the degree of the impact of trade facilitation in importing countries. Measures to jointly enhance trade facilitation among member countries under the RCEP framework are proposed.

Globally, Fintech, which acts to replace existing intranational payment methods, is actively used, and such Fintech payments are widely accepted in international B2C trade. However, Fintech for B2B trade has not been released to the market thus far, and previous attempts at electronic international payment systems, such as Bolero, TradeCard, and Identrus, have not succeeded, and most of them have completely disappeared. On the other hand, there are continuing attempts to introduce Fintech technologies such as blockchain to international payments, and these attempts are more widely pursued in foreign countries. If international payments using Fintech are marketed through foreign services and such Fintech services become the de-facto standard for international payments, then Korea in which dependency on international trade is high will be vulnerable due to a dependency on foreign services such as relying on foreign SNS platforms like Facebook and Instagram. Therefore, this paper proposes a business model that can be used as a legitimate B2B trade international payment system on the basis of domestically provided services, focusing on various services afforded by K-SURE, which is the Korea Trade Insurance Corporation.

This study aims to derive precaution points for issuing banks in refusing payment under L/C through literature review and examination of court cases and official opinions of ICC Banking Commission with regard to the provisions of article 16 of UCP 600 that stipulates obligations of issuing banks in refusing payment. If the issuing bank fails to act in accordance with this article, it shall be precluded from claiming that the documents do not constitute a complying presentation. Therefore, it is crucial that issuing banks should be well informed of this article. When discrepant documents are presented, however, issuing banks seldom refuse payment because, in most cases, the applicants waive the discrepancies. For this reason, issuing banks have few chances to deal with payment refusal in practice and thus they occasionally end up failing to observe the provisions of the article. Such court cases include Kookmin Bank and Korean Exchange Bank (currently Hana Bank) that failed to indicate discrepancies in the refusal notice losing the lawsuits. It should be noted that if issuing banks disregard the provisions of article 16 of UCP 600 and thus fail to indicate discrepancies in the refusal notice, they may face fatal situations in which they must make payment against discrepant documents.
