기존 상용의 스펙트럼 분석기를 이용한 EMI 분석장비들은 고정도의 측정결과를 내고 있으나 1차 검교정기관에서 주로 사용되고 있다. EMI가 환경문제의 일환으로 간주되면서 전자제품을 생산하는 업체의 생산라인마다 EMI분석 장치의 보급은 오실로 스코프와 같이 보편적인 장비로 사용해야하는 시점에 와 있다. 본 논문에서는 WIN CE를 이용한 EMI분석용 범용 Embedded System Platform의 개발은 물론 이를 산업용 제어기로의 적용할수 있는 임베디드 시스템에 관한 것이다. 특히 본 연구에서는 WIN CE기반의 임베디드 시스템 플레폼과 ATMEGA128을 Sub Mode로 하는 범용 제어 모듈의 소프트웨어 및 하드웨어 구조를 제안한다.

Cooperative spectrum sensing (CSS) for vacant licensed bands is one of the key techniques in cognitive radio networks. However, current CSS schemes focus on ensuring an efficient cooperation among secondary users (SUs), but ignoring their competition. At the same time when several SUs want to a vacant band, how to win this pop vacant band for an SU becomes more and more important. Inspired by the idea that an SU who always behaves well will win a pop vacant band more easily, we propose a competition scheme called BehaveWell (BW) in this paper. By analyzing the main threats against CSS, competitive coefficient is introduced to evaluate each SU's past behaviors in CSS. A higher competitive coefficient is very helpful for an SU to win a pop vacant band. This BW scheme can not only enhance a healthy competition among SUs, but also improve the security of CSS. Simulations verify the effectiveness of the proposed scheme.

E-sports has grown steadily in recent years and has become a popular sport in the world. In this paper, we propose a win-loss prediction model of League of Legends at the start of the game. In League of Legends, the combination of a champion statistics of the team that is made through each player's selection affects the win-loss of the game. The proposed model is a deep learning model based on Bidirectional LSTM embedding which considers a combination of champion statistics for each team without any domain knowledge. Compared with other prediction models, the highest prediction accuracy of 58.07% was evaluated in the proposed model considering a combination of champion statistics for each team.

A new blade has been developed to apply to Doosan 3MW offshore wind turbine named as WinDS3000TM. The 3MW blade has been designed by the concept of slim external shape and optimized structure. High-performance glass fiber reinforced epoxy composites were used as the main material of the blade. The blade was manufactured using vacuum infusion process in order to increase the fiber volume fraction and to reduce micro-porosities. The blade has successfully passed the full-scale blade static test for certification. During the test, micro-failure signal and strain change of the blade were measured using acoustic emission sensors and strain gages. The blade has robust structure and weighs lighter compared to conventional blade since the new blade was designed by optimization process. The 3MW blade will be commercially applied to WinDS$3000^{TM}$ in 2010.

This paper deals with the attrition rate of major facility such as a particular building that is one of the most important target in the war time. In order to estimate the attrition rate, we use JAWS, WinJMEM which are programed by JTCG/ME of AMSAA and spreadsheet package which is able to assist the limitation of those programs and calculate all the procedure of this computation. This method uses the effectiveness index(El) which indicates the numerical measure of the effectiveness of a given weapon of a given target. The range error probable(REP) and the deflection error probable(DEP) in the ground plane also should be used. Those mean the measure of delivery accuracy of the weapon system. In this paper, it is improved that the El can be obtained from the regression analysis using the weight of the warhead explosive as the independent variable. It implies that we are able to obtain the El and the conditional probability of damage of the enemy weapon. After that, the single-sortie probability of damage can be computed using WinJMEM or another assistant program such as the spreadsheet package which shows the result immediately.

The Industrial Innovation Movement, based on win-win cooperation with SMEs, is a structure that enables suppliers who have struggled with corporate growth through productivity innovation due to poor manufacturing environment and lack of innovation. To this end, consultants and technical experts will support production innovation activities to improve production methods and improve productivity through process and management consulting. The purpose of this study was to explore the driving factors of the industrial innovation movement to improve the corporate ecosystem by improving the productivity of SMEs using modified IPA. The research results are as follows. First, in order to revitalize the Industrial Innovation Movement, the CEO-related elements of the participating companies should be maintained and strengthened. The motivation, education support, innovation organizational culture, the establishment of an innovation promotion system requires centralization of efforts for improvement. Second, in order to revitalize the Industrial Innovation Movement, the consultant's ability to analyze problems and suggest alternatives should be continuously strengthened. Third, in terms of the Central Promotion Headquarters, it was found that the Industrial Innovation Movement would be successful if the public information, industrial inspection for benchmarking, and provision of various information to support innovation activities were urgently improved.

As the industry develops and quality of life increases, the concept of leisure is also changing. Bicycling is a healthy sport for exercising while enjoying nature, facilitating the enjoyment of a healthy life. As a result, the awareness surrounding bicycles has increased, and so has the interest in lighter and more luxurious carbon bikes. The number of domestic companies producing carbon bicycles frames is nil. In this study, we analyze the frames of existing foreign brands and analyze the deformation and stress concentration area according to the load of the frame, using the finite element analysis. In addition, we set up the range of stiffness based on the content of the structural analysis, to localize the carbon bicycle frame and famous foreign products, and compare the prototype with the stiffness by using bicycle molds for track races.

China's Belt and Road Initiative (BRI) is China's contribution to the need for the world to collectively address deficits of peace, development, governance, and problems relating to climate, the environment and human health. The rise of China and the BRI do challenge the current 'rules-based global order' and the economic dominance and moral, political, economic, and cultural leadership of the United States and its allies. However, China's goal is not hegemony but a multipolar world in which common values coexist with principles of peaceful coexistence (including non-interference in the internal affairs of sovereign states). The evolution of the BRI is outlined, and the ways in which it reflects Chinese interests are summarized, including its roles in addressing natural resource dependence and excess capacity, a transition from investment promotion and factor-intensive growth to going out and industrial upgrading, going West, and the effective deployment of China's foreign exchange assets. Although China does therefore potentially gain, the BRI is designed so that partners also gain in a quest for win-win co-operation and mutual benefit. The values that underlie this approach and the call for a community with a shared future are compared with competing western values, whose roots lie in Enlightenment thought and are associated with a record of colonialism and imperialism. In this light, the article concludes with a consideration of the global implications of the BRI, the challenges it confronts and the likelihood that the unipolar moment will give way to a multipolar global development path.

The criterion which judges an information retrieval system performance is to how many accurately retrieve an information that the user wants. The search result which uses only homograph has been appears the various documents that relates to each meaning of the word or intensively appears the documents that relates to specific meaning of it. So in this paper, we suggest semantic information retrieval technique using relation within User-Word Intelligent Network(U-WIN) to solve a disambiguation of query In our experiment, queries divide into two classes, the homograph used in terminology and the general homograph, and it sets the expansion query forms at "query + hypemym". Thus we found that only web document search's precision is average 73.5% and integrated search's precision is average 70% in two portal site. It means that U-WIN-Based semantic information retrieval technique can be used efficiently for a IR system.
