This study investigates cognitive and emotional changes in individuals to clarify the principle between artistic stimulation and business innovation idea generation based on phenomenological research methodology. We conducted in-depth interviews with six participants who participated in the artistic creation program of business art, and derived meanings from their experience. As a result, we presented 4 essential categories, 8 main subjects, and 20 sub-subjects; 1) Optimizing rational and creative thinking, 2) Projecting oneself to the artist, finding balance, 3) Having room in mind to view the surroundings, finding insight into the world, 4) Eureka moment, crossing the boundary between business and art. We also found out participants of the program 1) Gradually expanded the criteria, 2) In chaotic directions, and 3) Leaded business creativity through from a non-form to reality throughout the project experience, The attempt to identify business phenomena by using phenomenological qualitative research methods had an academic significance regarding the unfamiliarity of the method in the business administration area. Moreover, this study broadened the possibility of promoting creativity by art in business areas. The study verified the categories and subjects of the business art, paving the way towards application in the real business situation.

2015년 우리나라는 약 9,632억 달러의 무역규모와 약 902억 달러의 상품무역흑자를 달성한 반면, 서비스무역은 약 152억 달러의 적자를 기록하였다. WTO에 따르면 서비스무역은 부가가치 및 고용 창출효과가 높고, 국민의 소득수준, 삶의 질 등과 밀접하게 연결되는 특성을 가지고 있다. 본 연구는 2006년부터 2015년까지 12개 항목의 서비스무역 세분류통계 정보를 분석하고 지난 10년간 업종별 서비스무역의 대외경쟁력을 측정해 보았다. 분석결과 첫째, 상품무역규모대비 서비스무역규모는 점차 증가하고 있다. 둘째, 서비스무역 업종별 경쟁력분석을 통해 정책의 수립 및 지원의 우선순위를 고려할 수 있다. 마지막으로 서비스무역 내 업종 간 연계성과 서비스무역과 상품무역 간 연계성을 고려한 정책과제 수립이 필요하다고 할 수 있다.

For competitive hotel business, the hotel must have a sound prediction capability to balance the demand and supply of hospitality products. To have a sound prediction capability in the hotel, it should be prepared to be equipped with a new technology such as quantum computing. The quantum computing is a brand new cutting-edge technology. It will change hotel business and even the whole world too. Therefore, we study the impact of quantum computing on supply chain management (SCM) and hotel performance. Toward the goal we have developed the research model including six constructs: quantum (computing) prediction, communication, supplier relationship, service quality, non-financial performance, and financial performance. The result of the study shows a significant influence of quantum (computing) prediction on hotel performance through the mediating role of SCM in the hotel. Quantum prediction is highly significant in enhancing the SCM in the hotel. However, the direct effect between the quantum prediction and hotel performance is not significant. The finding indicates that hotels which would install the quantum computing technology and utilize the quantum prediction could hugely benefit from the performance improvement.

This paper applied a VAR model to analyze the effects of RMB exchange rate brought to processing trade, non-processing trade and FDI. Then we can get the results that the appreciation of RMB could not solve the problem of US trade deficit. It is more likely that the appreciation just can transfer the trade imbalance to other country with US, which could not radically solve the economic problems of US. Also this paper find that the data of service trade is surplus while the main goods deficit was occur in advanced technology product, especially in the information & communications trade And US has real advantage in these industries, so the situation will be changed if US decreased the barrier in these industries. In that way, the imbalance situation should be greatly reduced.

The purpose of the study is to contribute to the positive development of blockchain technology by providing data to examine security vulnerabilities and threats to blockchain-based services and review countermeasures. The findings of this study are as follows. Threats to the security of blockchain-based services can be classified into application security threats, smart contract security threats, and network (P2P) security threats. First, application security threats include wallet theft (e-wallet stealing), double spending (double payment attack), and cryptojacking (mining malware infection). Second, smart contract security threats are divided into reentrancy attacks, replay attacks, and balance increasing attacks. Third, network (P2P) security threats are divided into the 51% control attack, Sybil attack, balance attack, eclipse attack (spread false information attack), selfish mining (selfish mining monopoly), block withholding attack, DDoS attack (distributed service denial attack) and DNS/BGP hijacks. Through this study, it is possible to discuss the future plans of the blockchain technology-based ecosystem through understanding the functional characteristics of transparency or some privacy that can be obtained within the blockchain. It also supports effective coping with various security threats.

한국과 중국 모두 세계시장에서 재화무역에서는 수출경쟁력이 있고 서비스무역에서는 경쟁력이 없으나 양국은 서비스무역 비중이 확대되고 있고 FTA논의를 통해 양국간 서비스무역은 더욱더 확대될 전망이다. 이런 배경 하에서 본 논문은 한 중간 서비스산업의 부문별 수출경쟁력을 측정하는데 그 목적이 있다. IMF의 BOP 통계수치를 이용하여 한 중 양국의 서비스 무역에 대한 수출경쟁력을 측정하기 위해 무역특화지수(TSI), 수정현시비교우위(RSCA)지수와 국제시장점유율(IMS) 및 수출증가율을 사용해서 서비스무역의 국제경쟁력을 부문별로 비교분석하였다. 그 결과 한국은 운송서비스, 금융서비스, 특허권 등 사용료, 개인 문화 오락 부문 등 4개 부문에서, 중국은 여행서비스, 통신서비스, 보험, 컴퓨터 및 정보, 기타 사업서비스 부문 등 5개 부문에서 국제경쟁력을 가지는 것으로 평가되었다. 건설부문은 비교우위를 판정할 수 없었다. 그러나 중국이 비교우위를 가지고 있는 통신서비스와 컴퓨터 및 정보서비스부문은 비교우위격차가 축소되어 서비스무역의 국제경쟁력 강화노력이 이루어지면 중국보다 경쟁력에서 우위에 설 수 있다.

Recently, ASP business models based on Web services are attracting considerable attention and regarded as the next generation of the ASP business models. It is, however, undesirable for ASP users to adopt them simply because the Web services are the new trend in the IT world. Instead, an in-depth comparison of the benefits against the costs between the Web services based ASP business models and the traditional models are required. Furthermore, it is desirable that this comparative analysis should be applied from the ASP users' viewpoints rather than those of the government or ASP providers. So, we have applied a comparative ROI (Return on Investment) analysis from the ASP users' perspective and shown that the Web services based ASP business models (382%) are superior to the traditional models (280%) in terms of ROI. We have also employed Balanced Scorecard (BSC) framework to keep the balance between tangible and intangible benefits considering the characteristics of IT value measurement.

The increasing demand in promoting cloud computing in either business or other areas requires more security of a cloud storage system. Traditional cloud storage systems fail to protect data integrity information (DII), when the interactive messages between the client and the data storage server are sniffed. To protect DII and support public verifiability, we propose a data integrity verification scheme by deploying a designated confirmer signature DCS as a building block. The DCS scheme strikes the balance between public verifiable signatures and zero-knowledge proofs which can address disputes between the cloud storage server and any user, whoever acting as a malicious player during the two-round verification. In addition, our verification scheme remains blockless and stateless, which is important in conducting a secure and efficient cryptosystem. We perform security analysis and performance evaluation on our scheme, and compared with the existing schemes, the results show that our scheme is more secure and efficient.
