Cyberthreats and crimes have become common in society and demand the adoption of robust security measures. Financial cybercrimes, personal information breaches, and spam messages are now prevalent, while companies and nations face an increasing number of cyberthreats and attacks such as distributed denial of service, ransomware, and malware. As the overall socioeconomic landscape undergoes digitalization powered by big data, cloud computing, and artificial intelligence technologies, the importance of cybersecurity is expected to steadily increase. Developed nations are actively implementing various policies to strengthen cybersecurity and providing government support for research and development activities to bolster their domestic cybersecurity industries. In particular, the South Korean government has designated cybersecurity as one of the 12 nationwide strategic technology sectors. We examine the current landscape of cybersecurity companies and the information and communication technology supply chain, providing insights into the domestic cybersecurity market and suggesting implications for South Korea.

최근 세계 경제는 미국과 유럽의 재정위기로 기업의 유동성이 부족하게 되었고 기업경영 환경에 큰 어려움이 있다. 이런 시기에 공급업체와 조화롭고 협력적인 관계를 바탕으로 고객의 다양한 요구를 충족하는 것은 매우 중요해졌다. 현시대는 기업 혼자의 힘만으로는 새로운 경쟁적 요구상황을 충족시킬 수 없으므로 기업 간 상호관계를 증대시킬 필요성이 요구된다. 기업 간 경쟁에서 공급사슬 간 경쟁으로 변화하고 있다. 그러므로 공급사슬관리(SCM)를 통한 협력이 중요하게 되었다. 본 연구는 "공급사슬에서 기업 간 협력이 높을수록 절대적 물류성과와 상대적 물류성과가 개선될 수 있다"라는 연구명제를 제시하여 공급사슬기업간 의사소통, 정보기술의 사용, 파트너십, 성과모니터링을 통해 절대적 물류성과와 상대적 물류성과의 영향에 대해 알아보고자 한다.

It is important to understand the process of IT diffusion between organizations for meeting effectively IT progress and its changes. The previous studies provide, the process of IT diffusion between organizational members, organizational factors facilitating the assimilation of IT within the organization, and the organizational members' usage of communication channels in the IT adoption process. But they failed to provide comprehensively the diffusion process of IT between organizations. Therefore, an empirical research through a field survey has been performed to examine the diffusion process of RDB with 64 companies to overcome the limits of the previous studies. The purpose of this study is (1) to empirically examine the interaction of companies(prior adopters and potential adopters), (2) to look into the differences of the factors of organizational structure and the periods of RDB adoption process between OAE(Organizations Adopting Earlier) and OAL(Organizations Adopting Later), and the importance of communication channels used in IT planning stage and adoption stage, (3) to inquire into the difference of RDB performance between OAE and OAL. The results of this study indicate that there is no interaction between the prior adopters and the potential adopters. Also, there are great significant differences with regards to variables of CEO's age, CEO's concern on IT, formalization, centralization compensation systems, CIO's attitudes on changes, RDB adoption periods, performance of RDB. In addition, interpersonal channels have been much more used than mass communication channels in both IT planning stage and adoption stage. This study provides good guidelines to the companies and the vendors in shaping the strategies of IT adoption and IT diffusion respectively.

In the past, companies should make enormous facility investment and acquire a right to do business in order to join communication markets, but now they can do business without important facilities, such as communication networks. Such a movement to ease regulations about companies which want to newly join the communication industry is expected not only to change a competition frame of the mobile communication market but also to greatly affect the entire communication industry. Through this study aiming to look into a way to calculate a reasonable wholesale price related to the government's introduction of the Mobile Virtual Network Operator (MVNO) system, I came up with a following result. I applied the operating profit percentage and the ratio of operating gain to cost to the cost plus model and retail minus model, respectively, to calculate the wholesale price and found that when I calculated with the cost plus model applying the operating profit percentage, I could get the highest wholesale price. On the other hand, I got the lowest wholesale price with the retail minus model by applying the operating profit percentage. Division of expenses and calculation of profit percentage are important factors in calculating the wholesale price and such results are expected to help accurate calculation of the MVNO wholesale price.

The purpose of this study is to analyze various energy platforms using data in the US and to suggest directions and implications. Some of the leading energy platforms are selected and analyzed based on the opening platform model. We focus on the case analysis of the US utility companies. In case of the horizontal open platform, Green Button sponsor's 'Connect My Data (CMD)' driven by the government invites the utility companies to jointly develop the sponsor's data solution. In case of the vertical open platform, the certification program 'Share My Data (SMD)' allows backward compatibility, because the technical improvement is minimal. The utility companies benchmark Amazon's three-sided market mediation and prefer platform and category exclusivity. For the former, they have data analytics companies like Enervee, Opower and for the latter, they have electronics manufactures and energy service providers (ESPs) like Distributed Energy Resources (DERs). Based on this US case study, we suggest the energy platforms to open their platform for renewable energy supply, energy conservation, high-efficiency products, and residential DER dissemination. To successfully implement the government's energy transition policy, the US platforms should be benchmarked as a business model. Especially, it is needed for them to coordinate a platform ecosystem. To ensure trust in the products and services offered on the marketplace platform, platform's certification program is helpful.

As well as the development of the measurement of service quality, various kinds of service measurements are also being developed. Especially the mobile telecommunication service being representative to the mobile telecommunication company would be the mostly developed area. Its development can be understood along with the development of the telecommunication companies as well as cellular companies, not only the service alone. It is a differentiated phenomenon in the current research, such as the organic influence between the service quality and product. Of course there are such products placed on sale and enjoyed the common service, but at present there is another case that the product is on the market exclusively with the mobile company in here. This article is to estimate service efficiency for Mobile Communication and Cellular company. In this paper, We tried to measure the service quality and overall satisfaction by using Data Envelopment Analysis(DEA), degree of combination and top2box which is a little bit different methodology from traditional ones. This paper uses CCR model in DEA to measure service efficiency in the Mobile Communication.
