This study analyzed the policy dilemma for ICT SMEs venture companies that changed after COVID-19 based on the results of the cognitive map analysis for ICT SMEs venture policies. First, as a result of analyzing the cognitive map of ICT SMEs venture companies that have changed since COVID-19, ICT venture companies are expanding support for ICT venture companies due to the threat of COVID-19. However, in order to convert COVID-19 into an opportunity factor, it also shows a policy direction to achieve innovative growth by creating a new market through non-face-to-face industry revitalization based on digital transformation (digital new deal). As a result of the study, the policy measures of supporting DNA-centered convergence innovation technology, digital transformation (digital new deal), fostering ICT startups (K-Global project), and expanding support for ICT SMEs did not have a policy dilemma. However, although many support has been expanded for ICT SMEs due to COVID-19, it is difficult to find and foster ICT start-up companies, and globalization problems are occurring due to the decrease in exports to COVID-19, making it difficult to create new markets. There is a negative (-) perception of causality that ICT SMEs venture companies may face risks as jobs decrease and innovative growth cannot be led to the revitalization of the non-face-to-face industry. Therefore, it was found that both the flow of causal relationship between the expansion of support for ICT SMEs and the high growth of ICT SMEs is not + and has a policy dilemma in part.

After introducing the industry 4.0 policy, Korean government announced 'Digital New Deal' and 'Green New Deal' as 'Korean New Deal' in 2020. We analyzed Korea Institute of Geoscience and Mineral Resources (KIGAM)'s research projects related to that policy and conducted markets analysis focused on Digital Twin and environmental monitoring technologies. Regarding 'Data Dam' policy, we suggested the digital geo-contents with Augmented Reality (AR) & Virtual Reality (VR) and the public geo-data collection & sharing system. It is necessary to expand and support the smart mining and digital oil fields research for '5th generation mobile communication (5G) and artificial intelligence (AI) convergence into all industries' policy. Korean government is suggesting downtown 3D maps for 'Digital Twin' policy. KIGAM can provide 3D geological maps and Internet of Things (IoT) systems for social overhead capital (SOC) management. 'Green New Deal' proposed developing technologies for green industries including resource circulation, Carbon Capture Utilization and Storage (CCUS), and electric & hydrogen vehicles. KIGAM has carried out related research projects and currently conducts research on domestic energy storage minerals. Oil and gas industries are presented as representative applications of digital twin. Many progress is made in mining automation and digital mapping and Digital Twin Earth (DTE) is a emerging research subject. The emerging research subjects are deeply related to data analysis, simulation, AI, and the IoT, therefore KIGAM should collaborate with sensors and computing software & system companies.

This paper analyses the new discipline on state-owned enterprises contained in the recently concluded Trans Pacific Partnership Agreement, and evaluates various factors that influenced the shaping of its specific rules. The new discipline consolidates and strengthens related provisions in current trade regimes, reflects various aspects of trade disputes between China and the US, and adopts, as its general underlying rationale, the principle of competitive neutrality. The new discipline contains elements that may challenge the multilateral trade regime, and may serve as a role model in regulating state-owned enterprises, including subsidies in services trade in other on-going trade negotiations. The new regime makes us think hard about fundamental issues regarding enforcement of competition policy against state-owned enterprises, treatment of non-market economies, and how to deal with effects of subsidies in international trade, bringing competition issues back on the trade agenda.

Graphene, called the "dream material" is drawing attention as a groundbreaking new material that will lead the era of the 4th Industrial Revolution. Graphene has high strength, excellent electrical and thermal conductivity, excellent optical permeability, and excellent gas barrier properties. In this paper, as the South Korean government recently announced Green New Deal and Digital New Deal policy, we analyze graphene technology, which is also attracting attention for its application to Corona 19 biosensor, to understand its national R&D trend and knowledge structure, and to explore the possibility of its application. Firstly, 4,054 cases of national R&D project information for the last 10 years are collected from the National Science & Technology Information Service(NTIS) to analyze the trend of graphene-related R&D. Besides, projects classified as green technology are analyzed concerning the government's Green New Deal policy. Secondly, text mining analysis is conducted by collecting 500 recent graphene-related articles from e-newspapers. According to the analysis, the field with the largest number of projects was found to be high-efficiency secondary battery technology, and the proportion of total research funds was also the highest. It is expected that South Korea will lead the development of graphene technology in the future to become a world leader in diverse industries including electric vehicles, cellular phone batteries, next-generation semiconductors, 5G, and biosensors.

A great deal of attention has been given in recent years to large diameter specimen for evaluation of soft soil characteristics, and many studies and developments of the apparatus for obtaining large diameter undisturbed soil samples are in progress attempting to minimize the disturbance of samples for precise strength and consolidation tests in the laboratory. This paper introduces a new large diameter sampler(over 300mm diameter), which can take prefectly undisturbed sampling at any depths applying a new sampling technique. By comparing the results of consolidation tests it is shown that the samples obtained by this new apparatus are of a superior quality to that of samples obtained by conventional sampler(Nx, 75mm dia.) at the same depths.

Logic simulation is playing a very important role for design verification as circuits are larger and more complicated. However unknown values in 3 value simulators may generate the X-propagation problem which makes inaccurate output values. In this paper, a new partitioning method and a new simulation algorithm are developed to deal with the X-propagation problem efficiently. The new algorithm can optimize simulation time and accuracy by controlling partition depth. Benchmark results prove the effectiveness of the new simulation algorithm.

The contents of a new book currently in preparation are described. The dearth of books in the field of nuclear materials has left both students in nuclear materials classes and professionals in the same field without a resource for the broad fundamentals of this important sub-discipline of nuclear engineering. The new book is devoted entirely to materials problems in the core of light-water reactors, from the pressure vessel into the fuel. Key topics deal with the $UO_2$ fuel, Zircaloy cladding, stainless steel, and of course, water. The restriction to LWR materials does not mean a short monograph; the enormous quantity of experimental and theoretical work over the past 50 years on these materials presents a challenge of culling the most important features and explaining them in the simplest quantitative fashion. Moreover, LWRs will probably be the sole instrument of the return of nuclear energy in electric power production for the next decade or so. By that time, a new book will be needed.
