On a global level, the energy problem is a very important policy topic, particularly at a time when the nation relies on imports for more than 95% of its energy demand. The starting point of an energy policy should be in line with the international community's concern and cooperation regarding climate warming, and the logic of the new policy on renewable energy expansion in Korea, the pre-developed energy sector, and policy of deserting coal all support this aspect. In particular, to accommodate the rapid urbanization of mankind, the key words of the 4th Industrial Revolution are linking energy to IoT, artificial intelligence, block chain, cloud, and big data.

As the demand for high-performance semiconductors, such as chips for artificial intelligence and high-bandwidth memory devices, increases along with the limitations of ultrafine processing technology in the semiconductor in-line process, advanced packaging becomes an increasingly important breakthrough technology for further improving semiconductor performance. Major countries, including Korea, the United States, Taiwan, and China, and large companies are strengthening their technological industry capabilities through the development of advanced packaging technology and policy support. Nevertheless, Korea has a lower level of development of related technologies by approximately 66% compared with the most advanced countries. Therefore, we aim to discover the needs for an advanced packaging research and development (R&D) policy through written expert interviews and importance satisfaction analysis. As a result, various implications for R&D policy directions are suggested to strengthen the technological capabilities and R&D ecosystem of the Korean advanced packaging technology.

Although the telecommunications service industry has become a basic infrastructure component of the information and communication technology (ICT) industry, it is now losing its reputation as a cash cow due to achieving a saturation of service subscribers, especially in South Korea. With the exception of improving network speeds, network operators are experiencing difficulties in creating new innovations. Therefore, new innovations for the telecommunications service industry should be identified in conjunction with government policies for industry promotion. To examine the innovative capabilities of a specific industry, innovation system theories were used as a framework for research. However, existing innovation systems are limited with regard to explaining the openness of relationships and user participation which are general properties of the ICT industry. Moreover, as sources of innovative activity, additional values such as financial support and collaboration are more appropriate. This study presents a new innovation system based on innovation values. We analyze the telecommunications service industry and prioritize the importance of telecommunication policies within South Korea. An in-depth interview with experts based on the innovation system framework is conducted first. Next, innovation factors derived from the interview are applied within an analytic hierarchy process (AHP), leading to a prioritization of innovation factors for the telecommunications service industry.

The world mobile service is growing sharply and became bigger market than wired. So it is very needed to find the political way to promote mobile industry. The United States government recently decided to introduce new mobile policies for promoting mobile industry. Until now the telecommunications policies of the United States have affected policy developments for many countries including Korea. In this context, we studied the validity of introducing new mobile policies of the United States in Korea. We found that new mobile policies can cause the change of mobile market environment; mobile market power will be dispersed from network to content, application and devise, and new mobile market environment where consumers freely select and use network as well as content, application and devise will be made. Also we found empirically that if new policies are introduced in Korea, mobile industry will be promoted as Korean consumers use mobile services and goods quite actively in new mobile market. We think our results provide reasonable evidence to introduce new mobile policies in Korea.

This paper examines the causality issue between telecommunications investment and economic growth for South Korea by applying recently developed time series techniques. Tests for unit roots, co-integration, and Granger causality are presented. The results show that hi-directional causality runs from telecommunications investment to economic growth for South Korea. This means that increased telecommunications investment directly affects economic growth and an increase in real income also influences telecommunications investment. The study also discusses the implications of the results for addressing telecommunications policy in South Korea.

This paper analyzes the impact of the change in telecommunication regulation changes including the unification of telecommunication service on network investment. The unification of telecommunication service plays a role of separating behavior regulation from entrance regulation and reducing entrance constraints. Therefore, it is expected that the market spillover effect is high through the improvement of behavior regulation. In addition, the effects of the other regulation changes in the 2010 Telecommunications Business Act revision are analyzed. This paper discusses critical factors affecting the decision making process in respect to the firm level and analyzes the impact path guiding investment and innovation. The key findings are as follows. First, the impact of entrance deregulation depends on the intensity of deregulation. If the intensity is not high, this regulation increases the incentive on investment and innovation. However, if the intensity is high as shown in abolishing of licensing, it affects the incentive negatively. Second, if interconnection regulation focuses on existing facilities or the intensity is not strong, this light handed regulation might increase investment and innovation. However, if interconnection obligation is expanded to the facility not constructed or the facility applying new technology, this regulation might deteriorate investment. Third, price deregulation increases the competition of service but it also increases the business opportunity, which means positive effect on investment. Finally, the paper proposes the guideline for telecommunications policy.

Electronic cash affects central bank in many areas, in particular regarding the issuance of money, supervision of cashless payments, supervision of the banking system and monetary policy. The effects of electronic cash on central bank policies, the security and integrity of the payment system, and naturally also on single sector such as company engaged in the transport of money and valuables, depend mainly on the extent to which the new payment methods can replace cash. The possible development of electronic cash merits special attention from central banks for at least three reasons. First, central banks are concerned that the introduction of the new payment instrument should have no adverse effect on public confidence in the payment system and payment media. Second, although the substitution of electronic cash for other forms of money should not theoretically hamper central bank's ability to control the money supply, it might, however, have practial implications, at least in the long run, which need to be carefully examined. Third, because electronic cash may be used for payments of very small value, they have the potential, more than any other cashless instrument, to take over the role of notes and coins in the economy and, therefore, have implications for central bank's activities and revenues.

The explosive wireless data service requirement accompanied with carbon dioxide emission and consumption of traditional energy has put pressure on both industria and academia. Wireless networks powered with the uneven and intermittent generated renewable energy have been widely researched and lead to a new research paradigm called green communication. In this paper, we comprehensively consider the total generated renewable energy, QoS requirement and channel quality, then propose a utility based renewable energy allocation policy. The utility here means the satisfaction degree of users with a certain amount allocated renewable energy. The energy allocation problem is formulated as a constraint optimization problem and a heuristic algorithm with low complexity is derived to solve the raised problem. Numerical results show that the renewable energy allocation policy is applicable not only to soft QoS, but also to hard QoS and best effort QoS. When the renewable energy is very scarce, only users with good channel quality can achieve allocated energy.
