After being introduced "4th Industrial Revolution" in the Davos Forum 2016, it is continuously talked about "4th Industrial Revolution" as an industrial and social innovation momentum for solving structural problems of economy and society. In this situation, our government established "the Committee of 4th Industrial Revolution" as a control tower and announced a policy "4th Industrial Revolution recommendation for government" in 2019. The Ministry of National Defense is pursuing "4th Industrial Revolution" policies and organizing a team "4th Industrial Revolution Smart Defense Innovation Team" in accordance with government-wide policies from 2019. In this paper, I will look at the background and status of the Smart Defense Innovation policy. And I am proposing development plans to create practical results as like "Strengthening governance for the Smart Defense Innovation" and "Implementation of the budget for the Smart Defense Innovation" and so on.

Carbon nanotubes (CNT) emitter has widely become an attractive mechanism that draws growing interests for cold cathode field emission.$^{1,2}$ CNT yarns have demonstrated its potential as excellent field emitters.$^3$ Extensive simulations were carried out in designing a CNT yarn-based cathode assembly. The focal spot size dependence on the anode surface of the geometric parameters such as axial distance of the electrostatic focus lens from the cathode and the applied bias voltages at the cathode, grid mesh and electrostatic focus lens were studied. The detailed computer simulations using Opera 3D electromagnetic software$^4$ had revealed that a remarkable size of focal spot under a focusing lens triode type set-up design was achieved. The result of this optimization simulation would then be applied for the construction of the CNT yarn based micro-focus x-ray tube with its field emission characteristics evaluated.

The Purpose of this study is to empirically examine the impact of various internal and external innovation activities of SMEs on their innovation performances in the field of electronics and communication industry. Drawing upon the literature review, internal and external innovation activities are defined and conceptualized, and independent, dependent and moderator variables are developed. We have used survey-based data for this study from the survey of technology innovation activities in manufacturing industry, which was conducted by the Science and Technology Policy Institute (STEPI) in 2010. The main result of this study shows that there were no significant differences in the impact of innovation activities on market performance according to the size of SMEs. On the other hands, we found that there were significant differences in the impact of innovation activities on technological innovation performance according to the size of SMEs. Therefore, in order to make high technological innovation performance, companies in the field of electronics and communication industry need to properly implement the internal and external innovation activities by considering their size.

With the rapid development of the Fourth Industrial Revolution and digital transformation, scientific and technological innovation measures are being devised to overcome Korea's low-growth, high-cost structure. Accordingly, by examining the R&D investment evaluation system of R&D PIE (R&D Platform for Investment and Evaluation), which has been promoted by the Korean government in response to the Fourth Industrial Revolution, from the perspective of R&D transformation, this study aims to explore a new path for a sustainable national science and technology innovation system following digital transformation. In particular, from the perspective of R&D PIE, a MLP (Multi-level Perspective), which had been conducted as an abstract theoretical study, was attempted with specific cases and analysis for each of the three layers: niche, landscape, and regime. In conclusion, R&D PIE was intended to elevate the abstract R&D investment evaluation system to a platform that leads innovation in the digital space of the Fourth Industrial Revolution. In addition, it was confirmed that the R&D PIE could be replaced or enhanced as a platform for innovation in response to the Fourth Industrial Revolution, thereby providing an alternative to job creation and an escape from economic crisis.

We investigate the sensitivity of symmetry quantification algorithms based on the profile R-factor (R_p) and the normalized cross-correlation (NCC) coefficient (γ). A DM (Digital Micrograph^©) script embedded in the Gatan digital microscopy software is used to develop the symmetry quantification program. Using the Bloch method, a variety of CBED patterns are simulated and used to investigate the sensitivity of symmetry quantification algorithms. The quantification results show that two symmetry quantification coefficients are significantly sensitive to structural changes even for small strain values of < 1%.

The competitiveness of the service sector is driven by its productivity. Services innovation is essential to enhancing service productivity. This paper first presents a framework for services innovation. The framework consists of three main phases of a service lifecycle (namely, service development, service operation, and service improvement), which are supported by IT infrastructure and service R&D management functions. This paper then identifies major research issues that should be investigated in the near future. The current issues of three representative service industries (namely, healthcare service, telecommunications service, and financial service) are also discussed.

이 글은 사회문제 해결형 혁신정책의 관점에서 기존 혁신정책을 재해석하고 발전방향을 제시한다. 기존 산업혁신정책의 프레임과 다른 틀로 혁신활동과 정책을 살펴보는 것이다. 이를 위해 먼저 사회문제 해결형 혁신정책이 갖는 정의와 특성을 살펴본다. 여기서는 사회 기술시스템의 전환에 대한 전망과 시민사회의 참여에 대한 강조가 기존 관점과 차별화되는 점이라는 것을 논의한다. 다음에는 사회문제 해결형 혁신정책의 렌즈로 혁신정책의 요소들을 새롭게 해석한다. 혁신 거버넌스, 산업혁신정책, 지역혁신정책, 인프라 구축 정책과 같이 혁신정책의 핵심적 수단을 사회문제 해결형 혁신정책의 관점에서 새롭게 조명하고 발전방향을 제시한다. 이는 과학기술혁신정책을 지속가능한 시스템으로의 전환과 참여의 관점에서 접근하면서 기존 혁신정책 수단을 재해석하고 성찰하는 계기가 될 것이다.

The demand for energy is steadily rising because of rapid population growth and improvements in living standards. Consequently, extensive research is being conducted worldwide to enhance the energy supply. Transpiration power generation technology utilizes the vast availability of water, which encompasses more than 70% of the Earth's surface, offering the unique advantage of minimal temporal and spatial constraints over other forms of power generation. Various principles are involved in water-based energy harvesting. In this study, we focused on explaining the generation of energy through the streaming potential within the generator component. The generator was fabricated using sugar cubes, PDMS, carbon black, CTAB, and DI water. In addition, a straightforward and rapid manufacturing method for the generator was proposed. The PDMS generator developed in this study exhibits high performance with a voltage of 29.6 mV and a current of 8.29 µA and can generate power for over 40h. This study contributes to the future development of generators that can achieve high performance and long-term power generation.
