When a dynamic method is applied at the time of occurrence of an client's connection request for most of the online gaming server engine, the gaming server is processing a session connection, it's initialization. Yet, such a method will cause a lot of loading and bottle-neck in the gaming server at the same time. Therefore we propose the object polling scheme to minimizes a memory fragmentation and loading of the initialization on the client using a static allocation method for an efficient On-lin gaming serverin this paper. We implement the gaming server applying to our proposed scheme, and we show an improvement in our proposed scheme by performance analysis in this paper.

In this paper, we propose a development methodology of interactive stereoscopic image display system. In our case, we consider a multiple touch recognition technique as the interaction method. That's because we want to guarantee multiple user access and interaction to the content without any restriction. In this case, however, some restrictions are occurred on account of the distance between display and participants. For this reason, this paper propose an invisible interaction surfaces which are generated in the air. This surface is utilized as interaction medium instead of the display wall. We also present an effective way to generate and edit interactive stereoscopic images based on Game Engine.

애플의 iOS가 처음 출시되고 앱 마켓이 공급자와 소비자 모두에게 각광을 받으며 성공하자 구글에서도 Android를 내세워 구글 마켓을 오픈하였고 결국 다양한 종류, 높은 품질의 애플리케이션들이 사용자들에게 공급되게 되었다. 언제 어디서나 스마트 폰을 통해 고품질의 다양한 앱을 이용할 수 있다는 점이 부각되어 각 마켓의 다운로드 횟수가 급증하는 등 폭발적인 앱 시장을 이룩하게 되었다. 하지만 개발자의 입장에서는 같은 솔루션을 개발할 때 모든 플랫폼을 지원하기 위해 각각의 OS에 맞게 따로 개발하기 때문에 오히려 전체 개발기간이 늦어지는 요소가 되었다. 이런 비효율적인 개발 기간을 단축하기 위해 상용엔진을 구매하여 적용하는 경우가 있지만 영세한 규모의 프로젝트 팀에서 적용하기에는 무리가 있으며 엔진 자체를 배우거나 개발하려는 앱을 위한 커스터마이징하는 기간 역시 짧지 않아 좋은 선택이 될 수 없다. 이에 본 논문에서는 모바일 OS 크로스 플랫폼 지원이 가능한 게임 엔진을 구축하기 위한 방법을 설명하고 이를 활용하여 개발된 프로젝트를 테스트하여 초당 54~61frame 이라는 그래픽 출력 속도를 보임으로써 해당 엔진의 활용 가능성을 증명하였다.

With the rapid growth in media service platforms providing broadcast programs or content services, content production has become more important and competitive. As a strategy to meet the diverse needs of global consumers for a variety of content and to retain them as long-term repeat customers, global over-the-top service providers are increasing not only the number of content productions but also their production efficiency. Moreover, a considerable amount of scene composition in the flow of content production work appears to be combined with rendering technology from a game engine and converted to object-based computer programming, thereby enhancing the creativity, diversity, quality, and efficiency of content production. This study examines the latest technology trends in content production such as virtual studio technology, which has emerged as the center of content production, the use cases in various fields of artificial intelligence, and the metadata standards for content search or scene composition. This study also examines the possibility of using object-based computer programming as one of the future candidate technologies for content production.

Recently, as the expansion of the metaverse accelerated due to the spread of the non-face-to-face trend after the COVID-19 pandemic, various metaverse platforms using it have appeared. In this study, we propose research and development of a virtual reality spatial psychological counseling service platform utilizing the advantages of metaverse. A counseling service platform was developed through virtual reality hardware including Unity 3D game engine and Head Mounted Display. Counseling participants create and participate in their own avatars, and counseling facilitators respond to the situation and environment of the counseling target in various virtual environments. It was attempted to improve the efficiency of the counseling service by allowing the space and counselor avatar to be selected. Furthermore, various interactions were implemented, and development was carried out so that it could be extended and utilized for social activities such as group counseling and general meetings and presentations. In the future, through additional research and development, we will prove the practical effectiveness of the psychological counseling service platform developed by conducting clinical trials under the support of psychological counseling experts and participation in actual counseling.

2018 년 평창 동계올림픽부터 우리나라 사람들이 컬링이라는 종목에 큰 관심을 갖기 시작하였다. 하지만 이 종목을 직접 체험하거나 경기를 보기 위해서는 빙판이 있어야 하는 특수성과 비싼 장비, 찾아보기 힘든 경기장 등 여러 열악한 조건들 때문에 결국 올림픽 시즌에만 반짝 관심을 가졌다가 시들어버렸다. 이를 해결하기 위해서 우리는 Unity 라는 게임 엔진을 사용하여 사람들이 쉽게 접할 수 있는 컬링 게임을 제작하였다. 실제 컬링을 게임으로 만들기 위해 컬링에 필요한 도구들을 이미지로 제작하여 Unity 내부에서 저장 후 오브젝트에 입력하였고 물리 법칙을 구현하기 위해 Unity 상에서 방향, 세기, 속도, 충돌들을 프로그래밍하였으며 대한컬링연맹에 나와있는 컬링 경기 규칙서를 활용하여 게임에 적용하였다. 또한 컬링의 진행이 현실적인 운동과 비슷하게 하기 위하여 스크립트 안의 충돌 및 마찰 관련 계수를 조절하였고 이를 이용하여 반복한 결과값들을 수치화 하여 그래프로 작성해보았다. 추가적으로 컬링 게임의 점수판과 카메라 시점 등을 통해서 게임 사용자가 게임 진행에 있어서 도움이 되는 부분을 구현하였고 현실성을 위하여 Arduino 를 이용한 게임 패드를 제작하여 직접 게임하는 듯한 느낌을 들도록 하였다. 최종적으로 게임을 이용하여 컬링에 대한 이해도가 증가하고 사람들이 컬링이라는 비인기 종목에 한 걸음 더 접근할 수 있게 되고, 스포츠발전에 조금이나마 기여할 수 있게 될 것이다.
