This paper aims to research the technology level of sports industry, through analyzing the technology gap between Korea and other major countries (USA, Europe, Japan, and China), and provide a list of technologies to be prioritized for R&D investment by conducting an analysis of the strategic importance of various element technologies. The results of the analysis showed that the technology level of Korean sports industry currently stands at 70.5% of the country with the most advanced technology (the USA), and that the technology gap amounts to 4.8 years. It was also found that the USA is the country with the most advanced technology (100%) at present, followed by Europe (91.1%), Japan (88.3%), Korea (70.5%), and China (61.2%). To reduce the technology gap, we established a Strategic Zone (SZ) and derived three element technologies including 'design and production technologies for sports and game equipment' in the $1^{st}$ tier, nine element technologies including '3D motion analysis and simulation technology' in the $2^{nd}$ tier, and four element technologies including 'fitness/health promotion and management technology' in the $3^{rd}$ tier. The significance of this research is that it included five major technology categories of the sports industry in its analysis, selected an expert on sports industry technologies using the delphi method. Therefore, the results of this study may be suitable for use as basic data in establishing the R&D strategy for the future development of the sports industry.

The halophytes are considered less important in our field, as the land reclamation executed continuously by public or individual. So this research is to use plants more active on the reclaimed land and to verify their utility in the aspect of the landscape planning, design and complementaton. This research is performed at the construction site of Incheon International Airport in Youngjong-do located in West-sea of Korea. Following proposals are the major conclusions drawn from the research:1. The halophytes to be used in the vicinity of the water reservoir in orer to improve the ground for the introduction of new plants and prevent the water contaminatioin. 2. The halophytes to be used as a gound-cover which protects major structures nearby from being damaged by the salt content in the air. 3. Thd halophytes to be used as a unique and panoramic landscape element. They have various colors which change throughout a year. 4. Thd halophytes to be considered as a outdoor recreation resource. The halophytes planted area may be utilized as picnic area, outdoor event plaza, ball game ground, rough in the golf cource and etc. Additional usage of the land include the future rearch site for sea fronted ecological studies and pasture for cows and other livestock.

Virtual Reality makes a virtual environment more realistic and, furthermore, it provides a variety of experiences which we cannot have in reality. A drastic growth of GPU performance and increase of computing capability make virtual environment more realistic than ever. One important element of constructing virtual environment is to animate 3D characters. Many researchers have been studying 3D characters animating and a myriad of methods have been proposed to make them more realistic. In this paper, we discuss the technologies and characteristics of 3D character animation. We believe that realistic characters in Virtual Reality will be applied to various fields: education, film and game industry, business and, particularly, medical area such as telemedicine, virtual surgery, etc.

게임 산업이 고도의 성장을 이루고 있는 현재 게임시장에서 대두되고 있는 문제점은 개발업무에 대한 능력과 자질이다. 대부분의 게임 개발 업무의 방식이 주먹구구식의 개발을 통해 게임을 제작하고 있다. 하지만 이러한 점은 게임제작에서 중요한 요소인 개념유지와 의사소통에 대한 문제점들로 나타난다. 이러한 문제점을 해결하기 위해 본 논문에서는 게임의 개념 단계에서 기획자의 아이디어를 제시하는 모델링을 위해 표현되는 요소를 연구하여 게임의 개념을 유지하고 개발자와의 원활한 의사소통을 통해 작업효율을 증대 시킬 수 있다.

With the development of CUP speed and graphic technology, real-time simulation of deformable object is embossed as an essential issue in engineering field. Recently, it has been applied to the surgical training and game animation with haptic force feedback. But real time simulation of deformable objects is not easy because of the conflicting demands of speed and low latency and physical accuracy. In this study, we present the implementation of boundary element method(BEM) which is combined with the nonuniform B-spline surface. It is working together with the real-time simulation technique and the geometry data is altered by handling control points without preprocessing routine.

With the expansion of metaverse content and hardware platforms, various interactions in the virtual world have been built, raising expectations for an increase in immersion which is a major element of the metaverse. However, among hardware platforms that increase virtual immersion elements, the typical HMD platform can be a barrier to new user inflows due to its high cost. Thus, this paper focused on improving virtual-to-real interactions by extracting motion data using relatively inexpensive webcam equipment in PC environments, utilizing Unity game engines, Photon unity network, multi-platform implementations, and Barracuda neural network inference libraries.

본 연구는 최근에 개발된 게이미피케이션 개발 방법론 중 하나인 4F 프로세스 제안이 목적이다. 4F 프로세스의 효과성을 분석하기 위해, 게임과 게이미피케이션 관련 이론을 적용했고, 기존에 개발된 개발 방법론과의 비교 분석을 실시했다. 연구결과에 따르면, 본 연구진이 찾은 8개의 방법론보다 4F 프로세스가 비교적 높은 완성도를 가진 방법론임을 입증했다. 하지만 4F 프로세스에도 보완점은 존재했다. 본 연구결과를 바탕으로 4F 프로세스의 장단점에 대해 언급하고, 게이미피케이션 개발 방법론에 필요한 요소로 단계별 가이드라인 제시에 대해 제언했다.

As an engineered product, a software package has multiple dimensions that must be designed judiciously to enhance its competitive viability. Functionality, reliability and price are three such common dimensions. However, many software products are sold as bundles of individual components and the competitive impact of bundling has received less attention in the research literature. In this paper, we examine the implications of software vendors using bundling as an element of competitive strategy. A game theoretic model of the actions of an incumbent and a new entrant is developed and the impact on vendor and consumer welfare is analyzed. Numerical experiments with the model show that (i) increasing bundle size is an effective strategy for the incumbent to increase its payoff at the cost of the entrant's payoff and consumer surplus, especially when the entrant's quality is low (ii) in the presence of bundling, the entrant can still increase its own payoff and consumer surplus at the cost of the incumbent's payoff, by increasing product quality up to the level that best segments market demand with the incumbent and (iii) an increase in bundle size by the incumbent, or an increase in quality by the entrant, can both result in an increase of total surplus. Similar results are observed in a related case where the entrant offers free software bundles. Our results provide insights into how software vendors may strategically use bundling and quality as additional product dimensions in order to stay competitive in the market. These results also inform the competing vendors of the impact of bundling related public policy actions on their respective payoffs.

본 연구는 모바일 소셜 네트워크 게임의 몰입에 영향을 미치는 요인이 무엇인지 실증적으로 살펴보았다. 인터넷과 온라인 게임의 몰입 경험에 관한 선행 연구를 기반으로 몰입의 결정요인을 콘텐츠 요인 (그래픽디자인, 도전과제, 보상), 기기요인 (접근성, 조작성), 사회적 요인 (상호작용, 커뮤니티)으로 구분하여 도출하였다. 먼저, 개별 결정 요인과 몰입의 연관성을 상관 분석을 통해 살펴보았고, 어떤 요인이 몰입에 상대적으로 강한 영향을 미치는 지를 확인하기 위해 위계적 회귀분석을 실시하였다. 상관분석과 회귀분석이 공통적으로 보여주는 결과는 그래픽 디자인, 보상, 커뮤니티 활동은 게임 이용자의 몰입을 증가시키고, 반면에 도전과제와 조작성은 몰입에 별다른 영향을 미치지 않는다는 것이다. 또한 몰입에 미치는 상대적 영향력의 크기는 그래픽 디자인, 커뮤니티 활동, 보상의 순으로 나타났다.

과거 모자이크 기법은 바닥에 천을 깔고 타일을 수작업으로 붙여 제작하였다. 하지만 최근 기술의 발달로 데이터 저장 방식이 아날로그에서 디지털로 발전하여 컴퓨터를 통한 이미지 표현과 변환이 가능해지며 모자이크의 표현 기법 또한 다양하게 발전하고, 디지털로의 예술표현 방식으로도 사용되어지며 공학 분야에서도 그 제작 과정에 대한 연구들이 다양하다. 본 논문에서 제안하는 기법은 나선형으로 실시간 퍼져나가는 결정화(Crystallization)모자이크로 타일요소는 3D석영(Crystal)을 사용한다. 기존 연구들은 대체로 이미지를 좀 더 세밀하게 묘사하기 위함이 연구 목적의 주를 이루고 있지만 본 기법은 시도되지 않았던 나선 드로잉과 결정화를 접목하고 3D 공간에서의 새로운 모자이크 방식을 시도 한다. 또한 제안하는 기법의 대한 검증과 이를 기반으로 게임으로의 발전방향에 대해 모색한다. 본 기법을 바탕으로 제작된 작품 'Spiral Crystallization Photo' 는 MWU Award'18에서 Top27에 선정되었으며 Unite Seoul 2018에서 전시 되었다.
