Weapon System effectiveness indices are a key factor to the cost-effectiveness analysis in the process of allocating national resources in an optimal fashion. First part of this paper reviews the need of weapon -effectiveness indices, historical development of methodologies on military strength evaluation with various models of indices, and the interrelation-ship between weapon effectiveness indices and war-game. Second part of this paper analyzes the concepts and usage of the already developed methodologies, i .e., index of power, weapon lethality index (W.L.I.), index of fire power potential (I.F.P), fire power potential (F. P. P), and weapon effectiveness indices/weighted unit value (W. E. I/W. U. V.). Finally, weaknesses and limits of these methodologies are compared and evaluated. Result of this research shows that the W. L. I, I. F. P, and F. P. P seem to possess many non-scientific or ambiguous facets, but the W. E. I/W. U. V method produces more detailed, inclusive, and reasonable indices. The paper concludes with the emphasis on the importance of the provision of the theoretical bases to develop effectiveness indices which can be used to evaluate Korean weapon systems, and the early establishment of a specialized research group to manage and develop methodologies on the weapon effectiveness indices.

본 논문은 테러리스트와 복수의 테러 대상자 사이의 전략적 행동을 게임이론을 통해 분석한다. 기본모형은 테러리스트가 공격 여부와 그 대상을 선택하고 테러 대상자들은 각자 방어의 수위를 결정하는 게임으로서 테러의 발생확률이 내생적으로 결정되는 구조를 가지고 있다. 균형에서 테러 대상자들은 테러 공격을 서로에게 전가시키려 테러 방어에 과도한 투자를 하게 되며, 동일한 테러 대상자들도 서로 다른 수준의 방어 수위를 유지하게 된다. 균형의 결과는 테러 대상자들의 총합적 후생을 극대화하는 최적 선택에 비해 비효율적임을 보일 수 있는데, 이러한 문제는 원칙적으로 테러 대상자들이 상호 간에 위험을 분담하는 계약을 맺음으로써 해결할 수 있다. 하지만 그러한 계약들도 계약조건의 검증이 쉽지 않아 그 실효성에 제약이 있게 된다.

본 연구에서는 비교적 간단한 구현 기술과 저가의 플랫폼으로 가상현실 체험을 해볼 수 있는 콘텐츠를 개발하고자 효과적인 가상현실 경험의 구현 요소를 연구하였으며, 그 요소는 현실감과 몰입감, 환상감의 구현 및 Tangible interaction의 사용으로 요약되었다. 이러한 요소들을 적용하여 경험 디자인 컨셉을 도출하고 상대적 현실감이 높은 실사 비디오 영상의 대화면 프로젝션(projection)과 비전 트레킹(Vision Tracking) 기술을 활용한 플랫폼을 디자인하였으며, Tangible device의 자연스러운 인터렉션을 적용한 가상현실 콘텐츠를 디자인하였다. 디자인 결과물은 전시의 형태로 제시하여 일반 사용자들의 체험 기회를 넓히고자 하였으며, Class Xylophone 2003과 VR Class의 두 가지 사례 연구를 통하여 컨텐츠 및 인터렉션 컨셉의 타당성을 검증하였고 다양한 가상현실 콘텐츠와 그 상업적 활용 가능성을 보여줌으로서 가상현실 분야의 저변 확대에 기여하고자 하였다.

Taekwondo, Korean traditional martial art as one of the ten Korean cultural symbols, has acquired a reputation for introducing and globalizing Korean culture together with its standing as official Olympic Game in 2000, Sydney, Australia. Nevertheless the World Taekwondo Headquarters, Kukkiwon, which is an exclusive Taekwondo institution only accommodates for three thousand persons. Considering the worldwide reputation of Taekwondo, the scale of Kukkiwon leaves a big supply problem. This study therefore suggests the plan to design Taekwondo park that playa major role of Taekwondo development in the 21st century and represent the cultural heartland of Taekwondo. The study considers four points. The points are as follows: 1) Necessary programs drawn by analyzing and assessing Muju city as a site for Taekwondo park, then a survey conducted for potential visitors to a Taekwondo park. Under the theme of "A World Cultural Heritage Upon Our Own Lives", the park plan intends to become a shrine of Taekwondo as well as a big tourist attraction. 2) Programs are appropriate for the terms of the investment under the auspices of government, by considering potential visits and the site conditions. 3) The meaning of Taekwondo and its history should be reflected in the space distribution and facilities allotment. Three meaningful zones: symbolic zone, training zone and culture zone are considered in planning program and space distribution. 4) The plan also intends to harmonize with local development by groping Muju city's uplifting, not only designs a Taekwondo park.

Non-fungible tokens (NFTs) are interchangeable rights to digital assets such as art, in-game items, collectibles or music, etc. NFTs have the potential to be infinitely useful in many industries by increasing security and processing costs for transactions and providing a new platform for the gigeconomy to work through. Its markets have grown fast and significantly since early 2021. We investigate the uses of NFTs and research the facts and figures on the usage of NFTs supporting websites. Using daily data between 2019 to 2021. NFTs took the world by storm in 2021, bringing forth a digital art revolution while becoming one of the fastest-growing asset classes of the year. While the NFTs market has been growing at a rapid pace, many are still wary of entering it because of the theoretical insanity around its worth. NFTs have been out there for quite some time and this trend doesn't plan to go any further. NFTs services have many practical use cases and their potential will only grow over time. While celebrities dive into this marketplace to maintain their onlinepresence andincrease their Net worth.

This paper analyzes the role of absorptive capacity in R&D spillovers through strategic R&D investments in a game-theoretic framework. In the model, a firm's effective R&D is composed of idiosyncratic R&D, which produces its own innovations, and identical R&D, which improves absorptive capacity. The model shows that in the presence of absorptive capacity firms have a tendency to underinvest (overinvest) in idiosyncratic (identical) R&D relative to the social optimum. As the spillover becomes larger, firms decrease their own R&D while they become more inclined towards strategic exploitation of rivals' efforts. Since the former effect overpowers the latter, the total amount of R&D decreases as the spillover increases. This is socially undesirable, providing a potential justification for a governmental subsidy for idiosyncratic R&D and a tax on identical R&D. The findings may have important implications for newly industrialized or emerging countries that consider a redirection of national R&D policy and intellectual property rights (IPR) regime.

The mobile internet has grown ubiquitous across the globe with the widespread use of smart devices. However, the designs of modern mobile operating systems and their applications limit content retrieval with mobile applications. The mobile internet is not as accessible as the traditional web, having more man-made restrictions and lacking a unified approach for crawling and content retrieval. In this study, we propose an automatic and scalable mobile application content crawler, which can recognize the interaction paths of mobile applications, representing them as interaction graphs and automatically collecting content according to the graphs in a parallel manner. The crawler was verified by retrieving content from 50 non-game applications from the Google Play Store using the Android platform. The experiment showed the efficiency and scalability potential of our crawler for large-scale mobile internet content retrieval.

We have built a robot soccer system to participate in MIROSOT97. This paper represents hardware specification of our system and our strategy. We select a centralized on-line system for a soccer game. The paper explains hardware specifications of our system for later development. Also, the paper explains our strategy from two viewpoints. From the viewpoint of cooperation, some heuristic ideas are implemented. From the viewpoint of path plan, Cubic spline is used with cost function which minimized time, radius of curvature for smoothness, and obstacle potential field. Direct comparison will be realized in MIROSOT97.
