Virtual reality, which is attracting attention due to the 4th Industrial Revolution and commercialization of 5G technology, is expanding its scope from gaming to tourism, leisure, and education, and the VR market is expected to expand continuously. As the VR market scales up in Korea, theme parks combining virtual reality contents are spreading around the city center. Unlike the existing theme parks, VR Theme Park is a small amusement culture space that is organized indoors, and you can enjoy attractions (ride) that can be enjoyed in an amusement park with virtual reality contents. Virtual reality content, which has the same characteristics as a theme park whose purpose is to experience extraordinary experiences, provides high immersion and presence in combination with the physical stimulus of attraction. The virtual reality content combined with the attraction cannot be classified accurately with the existing classification method, so a new classification method is proposed according to the experience type and the installation type. The contents were categorized through the case of the domestic VR theme park, and the planning direction for the creation of the virtual reality attraction contents that was going on was sought.

Despite people's expectation, COVID-19 has turned out to be a burden people have to carry for a while. The age of "Untact" has come. While many outdoor activites have been restricted, it is crucial to find other ways to maintain physical/mental health ideally indoors. As a mediative gesture, people are now taking notice of 'Console games', through which they can party, travel, and exercise in virtual reality even harder than in real life. In thesis, we will examine Nintendo Switch Consoles in relation to direction Korean game industry has to take to maintain people's physical/mental health.

몰입형 비디오 부호화를 위한 MIV(MPEG Immersive Video) 표준은 제한된 3D 공간의 다양한 위치의 뷰(view)들을 효율적으로 압축하여 사용자에게 임의의 위치 및 방향에 대한 6 자유도(6DoF)의 몰입감을 제공한다. MIV 의 참조 소프트웨어인 TMIV(Test Model for Immersive Video)에서는 복수의 뷰 간 중복되는 영역을 제거하여 전송할 화소수를 줄이기 때문에 복호화기에서 렌더링(rendering)을 위해서 각 화소의 점유(occupancy) 정보도 전송되어야 한다. TMIV 는 점유맵을 깊이(depth) 아틀라스(atlas)에 포함하여 압축 전송하고, 부호화 오류로 인한 점유 정보 손실을 방지하기 위해 깊이값 표현을 위한 동적 범위의 일부를 보호대역(guard band)으로 할당한다. 이 보호대역을 줄여서 더 넓은 깊이값의 동적 범위를 사용하면 렌더링 화질을 개선시킬 수 있다. 따라서, 본 논문에서는 현재 TMIV 의 점유 정보 오류 분석을 바탕으로 이를 보정하는 기법을 제시하고, 깊이 동적 범위 확장에 따른 부호화 성능을 분석한다. 제안기법은 기존의 TMIV 와 비교하여 평균 1.3%의 BD-rate 성능 향상을 보여준다.

This study noted the recent impact of Coronavirus Disease-19 (Corona 19) on the environment surrounding the library, and investigated the libraries' response activities. In addition, related issues on news media and social media were detected based on text mining techniques to engage environmental changes surrounding the library. Key issues were derived from 1,852 news reports on the library related to the Corona 19 situation and 227,983 tweets related to the library during the Corona 19 epidemic. Through this, implications were derived: prolonged 'Untact' situations, increased e-book lending, improved expectations for online services and librarians, and re-conceptualized library space. In addition, the direction of future services was discussed by selecting representative examples of library services provided in the non-face-to-face (untact) situation and dividing them into books, services, and spaces.

According to the OECD's interim report on Korean education analysis held in 2020, the presenter, Andreas Schleicher, director of education for the OECD, said, "Korean students show a lot of fear, anxiety and nervousness about failure", referring to how Korean students feel anxious even if their test scores are good. It is a simple example, but as mentioned in a recent education announcement, it is a common sight among Korean students, and it is easily experienced while receiving education. As Korea has a high level of interest and enthusiasm for nurturing human resources, various methods must be considered and studied, and solutions to current problems, improvements, and directions for development is encouraged to be presented. This paper considered the methods for innovation of a learning space to improve the quality of school education, and systematically analyzed and organized the effects and impacts of providing a green environment among the methods and means. It is hoped that this study can serve as a small solution and play its role in solving the social problems of complex aspects of students presented previously.

In this study, we aim to design an action game that increases the user experience. In order to increase the immersion of the game, the characteristics of the game used by the user were analyzed, and the systemic and visual characteristics of the game were designed with reference to each characteristic. The proposed method uses Unity 3D to implement an interaction system between objects in the game and is designed in a way that allows users to immerse themselves in the game. To induce immersion through the visual elements of the game, 2D objects and players are placed in a 3D space, and a 2D dynamic light shader is added. It is composed of inter-combat rules and monster behavior pattern collision detection and event detection. The proposed method contained the user experience with the implementation thesis, and showed the game's possibility of leading the user's affordance.

In this study, a newly modified 3-dimensional strain-dependent hydraulic conductivity modification relation which incorporates the influences of normal deformation and shear dilation is suggested. Since rock mass is simulated as a orthogonally jointed medium, an anisotropic hydraulic conductivity field can be evaluated using that relation. The empirical relationship on the basis of GSI and disturbance factor has been used to estimate the value of a modulus reduction ratio (ratio of rock mass deformation modulus to rock matrix elastic modulus). Principal hydraulic conductivity directions is not generally coincident with the global coordinate due to the inclining of joint and the influence of joint inclination is evaluated under strain rotation. Result shows that change of hydraulic conductivity does decreases with the increase of GSI and disturbance factor has much effects on the hydraulic conductivity of rock mass getting GSI value above 50. It is found that the inclination of joint impacts on the variation of hydraulic conductivity.
