본 논문에서는 립모션 디바이스를 이용하여 손의 움직임을 계산하고 이로부터 저글링 운동 동작뿐 만 아니라 이것을 이용한 팔 근육을 연습할 수 있는 새로운 프레임워크를 제안한다. 제안된 방법은 실시간으로 동작하기 때문에 사용자의 동작에 맞춰진 분석을 할 수 있다. 본 논문의 프레임워크는 크게 세 부분으로 나누어진다. 우선, 1) 사용자가 공을 튕기는 이벤트 트리거를 손목 움직임으로부터 정의한 뒤, 2) 사용자의 손 위치를 기준으로 저글링 형태의 움직임을 공에 매핑시키기 위한 포물선 기반 입자 기법을 제안한다. 마지막으로, 3) 손목의 굽힘을 기반으로 근육의 활동 양을 시각화할 수 있는 기법을 제안한다. 결과적으로 본 논문의 프레임워크를 이용하면 실시간 저글링 게임을 할 수 있을 뿐만 아니라 사용자의 팔 근육 움직임을 실시간으로 분석할 수 있다.

본 논문에서는 마이크로소프트(Microsoft, MS) 홀로렌즈를 이용한 초몰입형(혹은 과몰입형) 캐주얼 공게임을 제안한다. 일반적인 가상현실콘텐츠는 시각적인 몰입만을 전달하지만, 경우에 따라서는 과몰입형 콘텐츠도 매우 중요하며, 본 논문에서는 XR환경에서 사용자에게 과몰입을 전달할 수 있는 새로운 프레임워크를 제안한다. 특히, 어린 아이들이 체험하는 형태의 콘텐츠들은 대부분 과몰입형적인 특징을 가지며, 본 논문에서는 실제 그와 유사한 공 게임을 XR환경에서 제작함으로써 사용자가의 몰입을 개선시킨다.

본 논문에서는 텍스처 합성 기술을 활용하여 가상의 거품 패턴 텍스처를 생성하기 위한 합성 데이터 구축 방법을 소개한다. 물리 기반 유체 시뮬레이션에서 거품 표현은 2차 효과(Secondary effects)로 분류되며, 그만큼 계산량이 큰 작업이다. 게임 업계에서는 저사양 디바이스에서도 실시간으로 게임이 실행되어야 하므로 상대적으로 계산량이 큰 물리 기반 시뮬레이션을 통해 거품을 표현하기 어렵다. 대부분 사용자가 임의로 그린 거품 패턴을 화면에 매핑하여 적은 계산량을 통해 거품을 표현하지만, 시뮬레이션을 통해 만들어진 데이터가 아니기 때문에 품질을 보장하기 어렵다. 본 논문에서는 물리 기반 시뮬레이션을 통해 만들어진 거품 패턴을 텍스처 합성 기술을 통해 재생산(Reproduction)함으로써 수작업으로 그린 거품 패턴에서는 표현하기 어려운 고품질 거품 패턴 텍스처를 만들어 낸다.

Over for the past 10 years, the increase in geometric progression for the internet traffic, has allowed the IP protocol framework to be the most important network technology. In addition, the internet service is being developed as a service mode differentiated, aiming to support the new-mode real-time multimedia services such as internet phone, video conference, cyber reality, and internet game, focusing on offering a latest service. These days, aiming to solve the need for broad bandwidth along with guaranteeing QoS, the WDM technology of offering multiple gigabit wavelengths is emerging as the core technology of next-generation optical internet backbone network. In the next-generation optical internet backbone network based on WDM, the QoS framework is one of fore subjects aiming to offer a service of guaranteeing QoS This study analyzes the requirements of performance related to QoS framework in IP Subnet and in WDM optical backbone network, and suggests optical QoS service framework differentiated. in order to guarantee end-to-end QoS through the next-generation optical internet backbone network, using GMPLS control protocol.

Gamification is an important technology for the museum experience in the future, but there is a lack in both its application and academic studies in Korea. Therefore this study targets the technical strategies of museum gamification by studying domestic and international cases. For this purpose, this study analyzes and compares the cases as personalization, and audience interaction of museum experience and sees how the structure of the digital program affects the museum experience in detail by applying MDA framework to the comparisons. For visitors' active interaction with the museums, gamification should be designed in a way to contribute to visual expression of self identity, utilization of the museum space, constructivist learning free from limit on space and time, and interaction with other people.

As people increasingly play online games, numerous new features have been proposed to increase players' log-on time at online gaming sites. However, few studies have investigated why people continue to play certain online games. This research would verify that enjoyment experience could be explained by the conceptual framework. In the first, this study results indicate that customers would show a higher level of loyalty if they had an optimal experience with the games. The state of flow was felt when players were aware of opportunities for personal interaction and social interaction. The personal interaction could be motivated either to achieve the high cognitive performance or by providing the equity of distribution of the objective performance in order to examine players' cognitive performance; the social interaction can be motivated either to enhance a high level of self-esteem of player or to achieve the positive reputation in order to evaluate their self-esteem. This finding can answer the questions of what enjoyment experience is and why players are repeatedly playing specific online games.

Motion graphic is the recently emerged technique which extends the ways of expression in video industry. Currently, it is worldwide trends that the image design gets more attention in the field of movie, advertisement, exhibition, web, mobile, games and new media, etc. With the development of computer's new technologies, VFX methods for the visual content is dynamically changed. Such production methods combine the real scenary and CG(Computer Graphic) to compose realistic scenes, which cannot be pictured in the ways of ordinary filming. This methods overcome the difference between the real and virtual world, maximize the expressive ways in graphics and real space. Match moving is technique of accurate matching between real and virtual camera to provide realistic scene. In this paper we propose the novel technique for motion graphic image production. In this framework we utilize the match moving methods to get the movements of the real camera into 3D layer data.

Starting point bias arises in the iterative bidding framework when the initial bid influences respondent's final bids. The bidding game has become the most commonly used method of asking the valuation question in contingent valuation studies. A bidding game is typically conducted by either personal or telephone interview. Bidding begins with an interviewer positing an initial bid (starting bid) to a respondent. If the respondent is willing to pay the initial bid, the interviewer revises the bid upward until a negative respondent is obtained. A negative response to the initial bid downward until an acceptable amount is found. The final bid is a measure of the respondent's Hicksian compensating or equivalent surplus for the item being valued. This paper explicity tested for starting point bias in bidding games. That is, it was asked whether final bids are influenced by the magnitude of the starting bids in the process of valuating the WTP when to improve the quality of running water in Seoul and its vicinity. The result shows staring point bias exists in the present data and its magnitude is ${\delta}$=-0.265237.

This paper proposes a real-time simulation technique for thin shells undergoing large deformation. Shells are thin objects such as leaves and papers that can be abstracted as 2D structures. Development of a satisfactory physical model that runs in real-time but produces visually convincing animation of thin shells has been remaining a challenge in computer graphics. Rather than resorting to shell theory which involves the most complex formulations in continuum mechanics, we adopt the energy functions from the discrete shells proposed by Grinspun et al. For real-time integration of the governing equation, we develop a modal warping technique for shells. This new simulation framework results from making extensions to the original modal warping technique which was developed for the simulation of 3D solids. We report experimental results, which show that the proposed method runs in real-time even for large meshes, and that it can simulate large bending and/or twisting deformations with acceptable realism.

We proposed a curriculum that can learn the principle of blockchain by using the gamification which can bring up the interest and concentration of the students by connecting the contents of the class with the game. The proposed method is to educate the blockchain in a game format and to solve the problem that can be easily accessed in everyday life by applying the blockchain. By strengthening the thinking ability of computing, By growing information processing capacity, communication capacity, and community capacity, students can naturally enhance their education capacity. It is expected that the blockchain curriculum using the proposed gamification can be used to improve the information curriculum.
