At the 8th National High-Performance Computing (HPC) Committee convened in 2021, the "National High-Performance Computing Innovation Strategy (draft) for the 4th Industrial Revolution Era" was deliberated and the original draft was approved. In this proposal, the Ministry of Science and ICT in KOREA announced three major plans and nine detailed projects with the vision of "Realizing the 4th industrial revolution quantum jumping by leaping into a high-performance computing powerhouse." Thereby the most important policy about national mid-term and long-term HPC development was established and called the HPC innovation strategy (hereinafter "the innovation strategy"). The three plans of the innovation strategy proposed by the government are: Strategic HPC infrastructure expansion; Secure source technologies; and Activate innovative HPC utilization. Each of the detailed projects has to be executed nationally and strategically. In this paper, we propose a strategy for the implementation of two items ("Strategic HPC infrastructure expansion" and "activate innovative HPC utilization") among these detailed plans.

Data, by itself, will not reveal the optimal policy choice. Nor will data alone tell us what problems to focus on or how to direct resources. It should be recognized upfront that data-driven policy making cannot provide all the answers to the challenges of good governance. Policy decisions always depend on a combination of facts, analysis, judgment, and values. In this paper, we research on factors to design an organizational policy making for Big Data.

In cognitive radio networks, the packet transmissions of the secondary users (SUs) can be interrupted randomly by the primary users (PUs). That is to say, the PU packets have preemptive priority over the SU packets. In order to enhance the quality of service (QoS) for the SUs, we propose a spectrum access strategy with an ${\alpha}$-Retry policy. A buffer is deployed for the SU packets. An interrupted SU packet will return to the buffer with probability ${\alpha}$ for later retrial, or leave the system with probability (1-${\alpha}$). For mathematical analysis, we build a preemptive priority queue and model the spectrum access strategy with an ${\alpha}$-Retry policy as a two-dimensional discrete-time Markov chain (DTMC).We give the transition probability matrix of the Markov chain and obtain the steady-state distribution. Accordingly, we derive the formulas for the blocked rate, the forced dropping rate, the throughput and the average delay of the SU packets. With numerical results, we show the influence of the retrial probability for the strategy proposed in this paper on different performance measures. Finally, based on the trade-off between different performance measures, we construct a cost function and optimize the retrial probabilities with respect to different system parameters by employing an iterative algorithm.

This study analyzed President Park's speeches and the government's industry policy in the field of information security using cognitive map. The relationship analysis between policy tool variables and policy goal variables was employed to derive revitalization strategy of information security. This paper found that entrepreneurship revitalization has very strong causality with expansion of domestic market and global market. But, on the other hand, HR development has very weak causality with job creation and future growth driver because the labor market in the information security industry is poor and its transfer rate to other industry is very high. This study showed that this cognitive map could be characterized by a scarcity of feedback loops and a strong emphasis on the positive loops in the structure of virtuous circle. In this paper, we also constructed a comprehensive cognitive map on the policy vision of information security, showing that there are a risk of cyber threat, an opportunity of new fusion security market, information security reinforcing circle, global economic circle, and domestic market circle.

Beginning of the human ecology in 1920s, the efforts for applying the environmental values to a policy have been embodied by the enactments of international agreement and relevant laws. The government has been struggling to adopt the environmental values for the policy by enacting the relevant laws and establishing the environmental value evaluation information (environmental conservation value assessment map, eco-natural map, biotope map). In spite of the efforts to apply the environmental value assessment information for the habitat potential of wildlife, the application is being challenged by the discrepancy in methods and criteria. Thus this study intends to measure the potential of wildlife habitat and apply it to the spatial value classification for the application plan of wildlife habitat potential in policy. Maxent was used for the habitat potential and the land types were classified depending on the surface and land use pattern of cadastral map. As a result, the policy matrix including conservation strategy(CS), restoration strategy(RS), practical use strategy(PS) and development strategy(DS) has been deduced as CS $13.05km^2$(2.38%), RS $1.64km^2$(0.30%), PS $162.42km^2$(29.57%) and DS $8.56km^2$(1.56%). CS was emerged mostly on forest valleys and farmlands, and RS was appeared in the road area near the conservation strategy areas. Boryung downtown and Daecheon Beach were the center of DS, while the forest and farmlands were presented as PS. It is significant that this study suggest the new approaching method by comparing the wildlife habitat potential with the land type. Since this study evaluated the environmental value by one species of leopard cat (Prionailurusbengalensis) with Maxent model, it is necessary to apply the habitat potential measuring method for various target species as further research.

This paper is to explore that there are structural problems in the Korea-U.S. Free Trade Agrement negotiation by examining the Korean FTA policy and to introduce some alternatives to overcome them. The structural problem stems in part from the inefficient system in FTA policy making and its implementation. Most importantly, there is a lack of ex-ante consensus building among stake-holders. As an alternative to the current FTA policy, we suggest two things. First, we argue that an FTA negotiation strategy should correspond to Korea's overall industrial development strategy. Second, the National Assembly should play an important part for enforce of trade policies as a tool for advancing a comprehensive strategic measures.

In order to meet various requirements for transmission quality of both primary users (PUs) and secondary users (SUs) in cognitive radio networks, we introduce a channel bonding mechanism for PUs and a channel reservation mechanism for SUs, then we propose a novel spectrum allocation strategy. Taking into account the mistake detection and false alarm due to imperfect channel sensing, we establish a three-dimensional Markov chain to model the stochastic process of the proposed strategy. Using the method of matrix geometric solution, we derive the performance measures in terms of interference rate of PU packets, average delay and throughput of SU packets. Moreover, we investigate the influence of the number of the reserved (resp. licensed) channels on the system performance with numerical experiments. Finally, to optimize the proposed strategy socially, we provide a charging policy for SU packets.

IT 기술의 성장에 기초한 우리 사회의 각종 뉴미디어의 개발과 도입의 속도, 보급과 서비스의 확산정도 등은 국제적 관심을 주도할 만큼 폭발적이다. 한편 국가 정보화 차원에서 강력한 정책 드라이브를 바탕으로 추진된 정보 인프라의 확대 역시 그에 못지않다. 그러나 문제는 뉴미디어-정보화 정책이 추구하는 산업경제적 가치창출, 사회문화적 가치창출, 지식기반의 확충을 통한 지식사회/지식국가의 토대구축이라는 정책목표가 '사회의 질적 발전(quality development of society)'보다는 '기술과 산업의 양적 성장(quantity growth of industry and technology)'이라는 편향적 형태로 진전되고 있다는 것이다. 이는 개별 정책의 결과이기도 하지만 보다 근본적으로는 개발주의 패러다임(developmentalism)에 기초하고 있는 뉴미디어-정보화 정책의 구조적인 문제에서 비롯된 것이다. 이를 극복하기 위해서 우선적으로 요구되는 것은 '지식 IT 전략(knowledge IT strategy)'에 기초한 뉴미디어-정보화의 질적 발전, 즉 원천기술과 특허의 확보와 그를 통한 기술표준의 구축, 내용과 수준을 갖춘 콘텐츠의 계발, 사회적 지식 네트워크의 구성 등에 부합하는 정책 패러다임으로의 전환이다.

The purpose of this paper is to find an appropriate policy for local government innovation step by step. In order to accomplish this purpose, we considered the characteristics and situation of Gumi city. Specifically, we analyzed the win-win strategy of the department for the largest local administration innovation. Finally, we found that the chief executive's leadership and other strategies such as the adjustment of the innovation propulsion system are key factors. Also, Managing the resistance to change appeared during the process of local administrative innovation is important. The failure of the policy for local government innovation is caused by the failure to manage the resistance. Thus, for government innovation to succeed, correct information provision, comprehensive participation of public officials and effective management of resistance is necessary.
