Web 2.0시대를 맞이하여 다양한 플랫폼으로부터 기업의 수많은 정보가 쏟아지고 있다. 그러나 셀 수 없이 많은 정보의 홍수 속에서 대중들의 호응을 얻기 위해 기업들은 각각의 플랫폼의 특징을 이해하고 이에 적합한 마케팅 전략을 구사해야 한다. 그러나 최근에 급격히 성장하고 있는 소셜네트워크(Social Network Service)에 관련한 연구는 많이 진행되었으나 특정 매체에 관한 연구는 상대적으로 부족한 실정이다. 본 연구는 한국과 미국의 소비자들에서 인스타그램 게시글 정보가 어떻게 받아들여지는지 분석하여 인스타그램 게시글 정보특성이 수용의도 및 구전효과에 어떠한 관계가 있는지를 정보유용성 매개효과를 통해 살펴보았다. 이 연구문제에 답하기 위해서 인스타그램의 주요 이용자인 한국과 미국 대학생을 대상으로 온라인 설문을 실시하였다. 그 결과 정보유용성은 인스타그램 게시글 정보특성과 수용의도 및 구전효과 사이에서 주요한 매개효과 역할을 하는 결과가 도출되었다.

블록체인은 거래의 기록인 트랜잭션을 관리하는 중앙서버 없이 분산네트워크에 참여하고 있는 모든 노드가 그 거래의 내용을 각자 관리하는 기술이다. 특정 기간의 거래 기록을 담고 있는 블록은 이전 블록에 대한 해쉬 값을 참조하여 블록체인에 연결되고, 새로운 블록이 추가된 체인은 다시 모든 노드와 공유한다. 기존의 인증서를 이용한 트랜잭션이 핀테크를 거쳐, 가까운 미래에는 블록체인을 이용하는 응용의 등장이 예상된다. 본 연구에서는 기존 모델의 문제점 등을 분석하고, 앞으로 도래될 블록체인을 적용한 거래모델을 제안한다. 다양한 응용 중에, 본 연구에서는 4차 산업혁명을 이끌 주제 중에서 에너지 판매시장을 목표로 거래모델을 전개한다. 제안한 모델의 분석결과, 기존의 방법보다 안전한 에너지 판매 거래의 가능성을 확신할 수 있었다.

Today distant oceans around the world are regarded as a major 'global commons' for international trade and transportation. Korea is not an exception, because Korea hugely depends on sea lines of communication (SLOC) for supplying vital commodities such as food and energy resource. As a result, assuring a free and safe use of distant ocean beyond territory is also an important agenda for Korea's maritime security. However there are a number of challenges for Korea to enjoy a free and safe use of distant ocean; dangers of regional maritime conflict in East Asia, naval arms race of China and Japan, and concerns on possible decline of U.S naval presence and power projection capabilities. These factors provide a reasonable basis for Republic of Korea Navy (ROKN) to pursue capabilities for major naval operations at distant ocean in a long-term perspective toward the year 2030. The introduction of aircraft carrier and nuclear-powered submarine is a key requirement for achieving this goal. ROKN needs to acquire a 'multi-role strategic landing platform' type of light aircraft carrier, which takes a role to escort naval task force by providing air superiority at distant ocean. Additionally nuclear-powered submarine will offer ROKN a formidable power to carry out offensive missions effectively at distant ocean.

This paper analyzes how the current Global Value Chain (GVC) of East Asia has been established, and attempts to project the future trajectory of GVC under New Normal in the global trading system. For this purpose, the framework of Ideology-Technology-Institution nexus is presented with focus on the dynamics of interplay between ideology and technology, duly recognizing the dual-aspect of technology- a platform for business and also for national defense. The paper analyzes how the Information and Communication Technology (ICT) of the 1990s played a role of "facilitator" in shaping the GVC of East Asia, where China plays 'factory for final assembly' and the US plays 'the largest consumer'. Under New Normal, digital technology is likely to play the opposite role of "disrupting" the GVC of East Asia, unlike ICT. The paper explores the mechanism behind this great disruption. What is driving New Normal is the US-China power competition, seeking for dominance in East Asia and beyond. This paper argues that New Normal is not temporary shock, but will last for some time. Under this presumption, the paper presents three scenarios for the future trajectory of GVC in East Asia.

In 2010, the United Nations Commission on International Trade Law (UNCITRAL) initiated work on the settlement of disputes in international e-commerce through online dispute resolution (ODR). The basic goal is to use ODR to resolve disputes with low value but high volume in international e-commerce. The background is that consumers have no way to solve their legal problems in this area. An ODR system is intended to create a new way to enforce their rights. However, the legal situations of the countries in the e-commerce sector, particularly in consumer protection, are very diverse. Thus, no reasonable model for conflict resolution is available. Some countries consider this as public policy and want absolute protection of their consumers. Other countries want to encourage freer e-commerce trading. This diversity of consumer protection policy is an obstacle to ODR. However, sooner or later, reaching an agreement is feasible because each representative is making a reasonable effort to reach the goal.

The climate projection with a high spatial resolution is required for the studies on regional climate changes. The Korea Meteorological Administration (KMA) has provided downscaled RCP (Representative Concentration Pathway) scenarios over Korea with 1 km spatial resolution. If there are additional climate projections produced by dynamically downscale, the quality of impacts and vulnerability assessments of Korea would be improved with uncertainty information. This technical note intends to instruct the methods to downscale the climate projections dynamically from the Community Earth System Model (CESM) to the Weather Research and Forecast (WRF) model. In particular, here we focus on the instruction to utilize CAM2WRF, a sub-program to link output of CESM to initial and boundary condition of WRF at Linux platform. We also provide the example of the dynamically downscaled results over Korean Peninsula with 50 km spatial resolution for August, 2020. This instruction can be helpful to utilize global scale climate scenarios for studying regional climate change over Korean peninsula with further validation and uncertainty/bias analysis.

This study comparatively analyzes the cases of CDMA (Code Division Multiple Access) and WIPI (Wireless Internet Platform for Interoperability) to find out the success and failure factors of technology policies in the field of mobile communication industry. For this purpose, the two cases are analyzed through a new analysis framework, which is made by combining System of Innovation with a range of variables derived from precedent studies, such as external environment, institutions, technological system, governance structure, and interactions of actors. The results of analysis show that in the CDMA case, the following factors led to success ; Korea made good use of the external opportunities in the early stage of digital communication technology and adopted a suitable governance structure for the technological system. Main actors in Innovation System had strong will for success and engaged in cooperative interaction. For the WIPI, however, the timing of technology policy was inappropriate and a unsuitable governance structure for technological system was chosen because of path dependence. The Innovation System failded to respond efficiently to the situation where conflicts among actors had intensified, US trade pressure had increased and innovative smartphones emerged. The results of this study provide the practical implications for the success of technology policy; namely it is important to choose a governance structure that suits the external environment and characteristics of technology and to activate cooperative interactions among actors in Innovation System.

Purpose - A framework is suggested in this paper which will help crowdfunding platforms to match projects according to expectations of funders, leading to successful campaigns and thus increase the profitability of the crowdfunding platform. Research design, data, and methodology - The paper is theoretical and conceptual in nature which proposes a model for crowdfunding platforms to match expectations of crowds with project fundraisers. Results - Crowdfunding platforms are going through incremental innovations in order to match customer (funders and fundraisers) expectations. Leading crowdfunding platforms like Kickstart holds benchmark for other players in the market but the secret of success lies in matching quality projects with the appropriate funders. Crowdfunding platforms have to securitize the projects and allow only quality projects but also provide a wide range of options for funders. Thus, to manage this trade-off between quality and quantity of options, a framework is proposed. Conclusions - Crowdfunding platforms have to adopt a model which will help them in providing a perfect match between crowds and fundraisers. Each member of the crowd and every project will be assigned a category and rating based on the past records. Securitization of projects will help to entertain only demanded projects which will reduce the number of failing campaigns.

Purpose: The article deals with the proposition that consumers' fashion consumption behavior will still follow the consumption behavior of fast fashion, despite recognizing the importance of slow fashion. Research design, data and methodology: The research model to verify this proposition is topic modelling with big data including unstructured textual data. we combined 5,506 news articles posted on Naver news search platform during the 2003-2019 period about fast fashion and slow fashion, high-frequency words have been derived, and topics have been found using LDA model. Based on these, we examined consumers' perception and consumption behavior on slow fashion through the analysis of Topic Network. Results: (1) Looking at the status of annual article collection, consumers' interest in slow fashion mainly began in 2005 and showed a steady increase up to 2019. (2) Term Frequency analysis showed that the keywords for slow fashion are the lowest, with consumers' consumption patterns continuing around 'brand.' (3) Each topic's weight in articles showed that 'social value' - which includes slow fashion - ranked sixth among the 9 topics, low linkage with other topics. (4) Lastly, 'brand' and 'fashion trend' were key topics, and the topic 'social value' accounted for a low proportion. Conclusion: Slow fashion was not a considerable factor of consumption behavior. Consumption patterns in fashion sector are still dominated by general consumption patterns centered on brands and fast fashion.
