The purpose of this study is to analyze the factors affecting innovation activities related to the introduction of the 4th Industrial Revolution technology for Korean firms faced to the severe global trade and competition environments. This paper conducted an empirical analysis using the 'The Survey of Business Activities' distributed by the Statistics Korea in 2019. According to the results of the analysis, it was found that the firm size, labor cost, R&D, and intellectual property rights had a significant influence on the firms' adoption of the 4th industrial revolution technology. It was also found that the dummy variables such as strategic alliance between companies, review of entry into a new business, transfer of main business operations, and holding of subsidiaries had statistically significant effects on innovation activities. In addition, this paper showed that the firm characteristics had impacts on innovation activities of firms by the 4th industrial revolution technology type. In order for Korean firms to adapt to the challenges by the 4th Industrial Revolution, it is important to provide policy support and an environment in line with the characteristics of the firms.

The development of information technology (IT) has led to changes in medical education. IT has been used for e-learning and e-teaching, e-assessment, e-logistics, and e-administration. Pusan National University School of Medicine has developed its own educational information system using IT to support students' learning and assessment and to manage curricular activities. Based on our experience, we propose six suggestions for designing new software, specifically regarding simplifying the design for users, communication with the programmer, a rapid cycle from design to implementation, orientation support for users, backup and security support, and obtaining patents. Collaborating with the Department of Medical Informatics within the School of Medicine has advantages, and an alliance among medical schools can simplify the development of software. In any case, curricular innovation should precede the introduction of technology because all technologies should support curricular goals.

Innovation Cosystems are Conceptualized as Organizational Networks of Economic Actors, Technologies and Social Contexts that Interact for Knowledge Production, use, and Adaptation. This Paper Proposed a Conceptual Framework to Describe Value Co-creation of Organizational Networks Engaged in Technology Innovation. We Adopted Theory-Based Approach by Integrating the Perspective of Service-Dominant (S-D) Logic Into the Evolutionary Model of the Triple Helix. The Framework Gives a Plausible Explanation on how Actors Collaborate to Create Value in Dynamic Contexts of an Innovation Ecosystem. The Innovation Ecosystem can be Considered as a Composite of Sub-Ecosystems, Including Knowledge, Sectoral, and Business Ecosystems. When these Sub-Ecosystems are Recursively Transformed by Coordination of Functional Mechanisms that Serve Value Co-creation in the Innovation Process, the Innovation Ecosystem will be Re-Organized and Evolve. The case of the Digital Living Network Alliance (DLNA) was Examined to Demonstrate the Fundamental Mechanisms for Value Co-creation that was Described in the Framework. The case Study Indicates Features of Value Co-creation when Implementing Innovation in Organizational Networks.

The pressing need to mitigate greenhouse gas emissions has stimulated a renewed interest in nuclear energy worldwide. However, while numerous countries have shown interest in nuclear power over the course of history, many of them have not continued their pursuit and chosen to defer or abandon their peaceful nuclear power projects. Scrapping a national nuclear power program after making initial efforts implies significant challenges in such a course or a waste of national resources. Therefore, this study aims to identify the crucial factors that influence a country's decision to terminate or hold off its peaceful nuclear power programs. Our empirical analyses demonstrate that major nuclear accidents and leadership changes are significant factors that lead countries to terminate or defer their nuclear power programs. Additionally, we highlight that domestic politics (democracy), lack of military alliance with major nuclear suppliers, low electricity demand, and national energy security environments (energy import, crude oil price) can hamper a country's possibility of regaining interest in a nuclear power program after it has been scrapped, suspended, or deferred. The findings of this study have significant implications for policymakers and stakeholders in the energy sector as they strive to balance the competing demands of energy security, and environmental sustainability.

본 논문의 목적은 미국의 상쇄전략 개념을 발전적으로 검토하여 4차 산업혁명 기술혁신을 적용하고 국방개혁 2.0과 연계한 북한의 핵 위협에 대응하기 위한 방안을 제시한 것이다. 남북, 미 북 정상회담을 통하여 북한의 완전한 비핵화를 달성하기 위한 다양한 협상을 진행하고 있으나 2019년 베트남 하노이에서의 미 북 정상회담 결렬 등 북한의 완전한 비핵화를 달성하기까지는 많은 시간과 노력이 필요한 실정이다. 이에 현실화된 북한의 핵 위협에 대응하기 위한 개념과 기술, 조직을 발전적으로 검토하였다. 대응개념은 미국의 상쇄전략 추진사항을 발전적으로 검토하여 '적 중심 마비작전'을 작전개념으로, 이를 뒷받침할 수 있는 기술은 4차 산업혁명 기술혁신과 미국의 3차 상쇄전략 추진 사항을, 조직은 국방개혁 2.0 추진과 미국의 국방부 획득조직 개편에 대한 시사점을 분석하여 발전적인 방안을 도출하였다. 미국의 전략적인 개념의 일치가 필요한 부분이 있고, 기술의 상호운용성, 한 미동맹 차원의 협력분야를 도출하였다. 그리고 4차 산업혁명 기술혁신과 국방개혁 2.0 추진 사항을 연계하여 북핵 대응 역량을 강화할 필요가 있음을 도출하였다. 북핵 대응을 위한 작전수행 개념의 발전을 위해 새로운 패러다임을 적용이 필요하였으며 미국의 '국제공역에서의 접근과 기동을 위한 작전개념'(JAM-GC)를 벤치마킹하여 '적 중심 마비전' 작전개념을 제안하였다. 북한의 비핵화 협상이 진행 중인 점과 4차 산업혁명 기술혁신의 방대함, 국방개혁 2.0과의 연계성, 한반도 평화프로세스와의 접목 등을 고려할 때 더욱 정교하고 세밀한 북핵 대응방안의 발전이 필요할 것이다.

The purpose of this study is to empirically analyze whether open innovation activities are significant and which methods are more effective in developing new businesses. Based on the latest technological innovation survey data of the Science and Technology Policy Institute, the results were analyzed by binary logistic regression analysis. As a result of the analysis, we confirmed that open innovation activities have a positive effect on the performance of developing new businesses. In the open innovation activities, Recruitment (invitation) of specialist in related fields, Business alliance technical agreement, Dispatch of personnel, M&A, Acquisitions identify related field trends showed more influence in order. It would be beneficial to improve the performance of developing new businesses with a low probability of success if utilize more effective innovation activities in developing new business in enterprises or organizations throughout this study.

This study analyses the transformation of Asian steel trade and the change of corporate strategy. The purpose of this paper is to examine the circumstances of Asian steel industrial policies, and considering the feature of each nation's steel industrial policies, and the effect of the corporate strategy. In China, mighty steel productive capacity had already formed under original planned economy and industrial policy. In 2003, crude steel production have exceeded 220 million ton in China and that is 23.2% of the steel production share in the world. On the other hand, not only the amount but also the quality becomes an important point in the steel industry in the future. I consider, on researching Asian steel industry, it is important to build up partnership in Korea and Japan for achieve strategic alliance in the steel industry policies and understanding the change of corporate strategy.

The hydrogenated amorphous silicon thin film transistor (a-Si:H TFT) with copper as source and drain electrode has been fabricated to obtain its transfer characteristics and stressed with positive and negative bias to investigate the instability variation comparing to conventional MoW-Al based TFT device. The results show that there is no copper diffusion into active layer of a-Si:H TFT, even during the thermal process. In addition, a 15-inch XGA a Si:H TFT LCD display utilizing Cu as gate electrodes has been developed.

In this paper we present geometrically exact Kirchhoff's initially curved planar beam model. The theoretical formulation of the proposed model is based upon Reissner's geometrically exact beam formulation presented in classical works as a starting point, but with imposed Kirchhoff's constraint in the rotated strain measure. Such constraint imposes that shear deformation becomes negligible, and as a result, curvature depends on the second derivative of displacements. The constitutive law is plasticity with linear hardening, defined separately for axial and bending response. We construct discrete approximation by using Hermite's polynomials, for both position vector and displacements, and present the finite element arrays and details of numerical implementation. Several numerical examples are presented in order to illustrate an excellent performance of the proposed beam model.
