This paper investigates two kinds of strategic combinations carried out by the European telecom operators between 1986 and 2001: acquisitions, on the one hand, and strategic alliances, on the other. The aim of the paper is twofold. First, it analyzes the behavior adopted by these companies to adapt to an environment that, after the processes of globalization and privatization presents a clearly different structure. Second, it focuses on the effect that internationalization and diversification could exert over the returns obtained by the European telecom firms involved in acquisitions and alliances, differentiating when such strategic combinations are more profitable for the shareholders of the firms that carry them out.

카자흐스탄은 한국의 기술과 문화에 대해 높게 평가하고 있으며 한국을 자국 경제발전의 롤모델로 인식하고 양국 간 관계를 전략적 동반자 관계로 격상시키는 한편 협력 분야를 에너지, 자원 분야에서 기초과학과 IT 분야로 확대하고 있다. ICT는 카자흐스탄이 산업 다각화를 위해 전략적으로 육성하고자 하는 분야로 막대한 ICT 프로젝트를 제시하며 세계적인 경쟁력을 가진 우리 ICT 기업의 투자와 참여를 적극 요청하고 있다. 카자흐스탄과는 과거 (주)대우의 카작텔레콤 인수를 시작으로 ETRI의 우정, 이러닝 등 기술 지원 사업과 정책자문 등 다양한 협력 사업 경험을 가지고 있다. 그러나 양국 정부의 지원을 바탕으로 협력 사업을 진행하는 공공기관이나 충분한 자체 사업 역량을 보유한 대기업에 비해 모든 면에서 열세인 중소기업은 정확한 정보를 바탕으로 구체적인 전략을 수립하고 현지에 진출해야만 성공할 가능성이 높다. 따라서 본고에서는 우리 ICT 기업의 카자흐스탄 시장 진출을 지원하기 위한 사전 연구로서 ICT 시장 현황을 파악하고 현지 시장 진출 시 고려해야 할 요인들을 소개하고, 전략적 접근 방법을 제시하고자 한다.

In general, virtual reality (VR) and augmented reality (AR) are technologies used to overcome the limitations of space and time in human communications. Currently, VR and AR companies are mostly developing contents for a single user. However, it is expected that there will be a need for sharing experiences among two or more users in a VR/AR environment. In this paper, we investigate the trends in remote collaboration technologies for VR/AR that allow two or more users to share video, voice, and gestures, as well as emotions. We will also discuss the future of such technologies.

"Artificial Intelligence+" is a key strategic direction that has garnered the attention of several global medical device manufacturers and internet companies. Large hospitals are actively involved in different types of medical AI research and cooperation projects. Medical AI is expected to create numerous opportunities and advancements in areas such as medical imaging, computer aided diagnostics and clinical decision support, new drug development, personal healthcare, pathology analysis, and genetic disease prediction. On the contrary, some studies on the limitations and problems in current conditions such as lack of clinical validation, difficulty in performance comparison, lack of interoperability, adversarial attacks, and computational manipulations are being published. Overall, the medical AI field is in a paradigm shift. Regarding international standardization, the work on the top 10 standardization issues is witnessing rapid progress and the competition for standard development has become fierce.

Immersive media, which maximizes the viewer's sense of presence and immersion, has been developed in the form of 3D stereoscopic media and UHD media. Going one step further, VR media, which can provide immersive experiences within an artificially created environment, have recently been considered a type of next-generation media. Within this trend, numerous IT and broadcasting companies around the world are actively investing their time and resources to boost the emerging VR industry. In this paper, we introduce the representative VR media acquisition and broadcasting service technologies that are leading the current VR industry.

Korean telecommunications industry has a large scale market and boasts on high service quality and high technologies enough to provide the mobile video telephony service(the VTS) satisfactorily. For many years, Korean telecommunications companies have been investing enormous amount of money to advertise their VTS widely and to allow their customers to change their cell phones for the 3G(the third generation) devices indispensable for the VTS. However, despite their efforts, the VTS adoption rate in Korea is very low as of January, 2010 and it seems that customers seldom feel the necessity to use. From this viewpoint, it becomes necessary to identify antecedents influencing the intention to use for the VTS empirically. For this purpose, we have proposed several hypotheses from the perspective of the Value-based Adoption Model(VAM). We conducted a survey and found the several factors which influence the value perception of VTS.

As companies use increasing amounts of data more and more, people are more concerned about protecting their privacy. Many researches studies have been conducted with a to securely view of manage managing and share sharing private information securely using the Bblockchain technology. These studies have suggested a Bblockchain-based approaches to provide efficiency, scalability, data ownership, and systematic data lifecycles that were are the limitations of lacking in traditional access controls. More Sspecifically, these studies have introduced a new access control models, distributed hash tables, trusted execution environments, and hierarchical ID-based cryptographic mechanisms to provide reliable access control even in complex environments such as IoT Internet of Things. In this paperstudy, we present the criteria to for classifying the functional characteristics of the Bblockchain-based access control methods and derive the differentiateion between of each the several methods.

Digital twins are digital replicas of objects and systems in the real world. These digital replicas in a virtual environment can be connected with smart sensors and a variety of analyses, and simulations of real-time data from these sensors enable effective the operation, rapid feedback, and future predictions of real world phenomena. Until now, digital twins have been adopted and used mainly in the field of manufacturing, especially for smart factories. As digital twins are expected to be useful not only for productivity improvement but also for social problem solving, it is predicted that they will be extended to other fields such as those of transportation and cities. Digital twins will especially help realize smart cities through real-time monitoring, operation, and predictions using virtual digital twin cities. This paper summarizes the trends in digital twins for smart cities, the concept of digital twins, their application to smart cities, the strategies of various countries, and the development status of companies.

In this study, we analyze the automotive chip ecosystem that recently caused the global supply shortage, and attempt to derive policy implications for us from the conclusion. Automotive chips are critical parts that control various systems so that a vehicle can drive itself or operate with electricity. The current shortage in supply and demand for automotive chips is due to the inconsistency between supply and demand between automotive chip companies and car manufacturers. To promote the automotive chip industry, new investment incentives, tax cuts, and human resource training are needed.
