최근 오픈마켓의 급속한 성장과 함께 다중 플랫폼을 위한 콘텐츠 시장이 확대되고 있다. 특히 오픈마켓에 등록된 콘텐츠의 약 15%가 게임콘텐츠가 차지할 만큼 게임은 오픈마켓에서 중요한 비중을 차지하고 있고, 다양한 부가가치를 창출하고 있다. 시뮬레이션게임은 크게 전략시뮬레이션게임, 레이싱시뮬레이션게임, 경영시뮬레이션게임, 육성시뮬레이션게임 등 플레이어의 역할 및 게임의 목적에 따라 다양하게 구분되고 있다. 본 논문에서는 기후변화와 기상 이변으로 인한 환경파괴를 게임배경으로 하여 식물과 동물들이 살아갈 수 있는 환경을 만드는 것을 게임컨셉으로 하였으며, 다중 플랫폼 기반의 육성시뮬레이션장르에 경영적인 측면과 교육적인 기능성게임의 요소를 포함한 게임을 개발하였다.

When a designer creates a new web-based learning-teaching system, there are so many considerations to help learners' learning effect through effective interaction. First of all, web-based simulation is recommended to provide learners with effective and attractive learning environments in web. Efficient study design should be considered because well designed simulation-based contents provide continuous interest for learner. Until now many e-Learning systems provide web-based simulation using various technique. However, those contents require to be reorganized considering the level of accomplishment, learning styles. In this paper, I proposed a system that the learners can share simulation objects among other e-Learning systems using XML web service. By experimental result, the proposed system shows that is more efficient than the conventional system in the self-leading study activity and interactivity.

In physics, metal simulation is an important mechanism to understand and create concepts. If students have difficulty in mental simulation, understanding the concept of physics also gets difficult. By providing guide for spatial manipulation to students, 3D simulation contents can help them understand the concept of physics. In this study, the 3D simulation contents developed to help understanding the concept of light going straight and shadow is applied to 20 college students. The results, Hake gain is 0.93, showing high level of understanding about the class. In addition, through mental simulation, students predict the phenomenon well about the new context. This is shown that students' understanding of concept through 3D simulation contents are carried out well.

This paper presents a fire and smoke animation system using stable fluid animation techniques. Stable and fast fluid simulation methods are developed in PC and console games, but fluid simulation and interactive fluid models still have many problems. We studied and implemented physics-based models for fluids like fire and smoke effects using mobile 3D system. The mobile platform of our system is WIPI, which are the standard mobile platform in Korea also we adopted NF3D API for our 3D programming API.

최근 스마트폰은 가장 대중적인 모바일 기기로서 초중등 학생들의 교육적인 활용 가능성은 다른 IT 기기에 비해서 높다고 할 수 있다. 또한 교육용 소프트웨어 중에서 컴퓨터의 잠재성을 가장 잘 보여줄 수 있는 것은 시뮬레이션이다. 그러나 스마트폰에서 실행되는 교육용 소프트웨어는 다른 모바일 기기에 비해서 특히 작은 화면에 대한 제약 등을 고려해야 하는 특성을 가지고 있다. 이 논문에서는 대표적인 시뮬레이션형 교육용 앱들을 분석하고, 이를 토대로 스마트폰의 특성을 고려한 교육용 콘텐츠 개발전략을 제시하였다.

This paper aims at implementing experimental devices with which middle school students can explore scientific ideas using GoGo Board and NetLogo that connect real and simulated worlds. Related research literature was reviewed to design a simulation-based learning model using computer simulation and robot-related activities. In order to construct devices for exploratory experiments, GoGo Board was adopted for developing the interface of Micro-Based Laboratory(MBL) devices with several sensors while NetLogo was used for connecting MBL devices (real world) and simulated experiments (virtual world). The simulation contents were developed in the area of heat equilibrium for changing temperature and the conduct-current relationship appeared in the textbook of middle school science class. With the developed device and contents students can visualize the change of temperature cold and hot waters in terms of heat equilibrium. They also can measure the change of conductor representing the relationship between conductor and current. The formative evaluation of the contents carried out with several middle school students indicated the future direction for upgrading simulation contents and interface. The results might be beneficial for science educators who want to apply simulation contents with the use of computers.

캡스톤 기업 연계형의 과제로 드론 교육에 쓰이는 시뮬레이션을 대체할 드론 교육 게임을 제작한다. 교육생의 입장에서 시뮬레이션은 복잡하고 지루하기 때문에 다양한 교육과 정보, 재미있는 콘텐츠를 담은 드론 게임을 만들어 스스로 학습을 진행하게 하는 것이 목표이다. 제작에 앞서 먼저 연구된 시뮬레이션과 게임을 통해 어떤 문제로 상용화가 되기 힘이 들었는지 조사했다. 재미있는 콘텐츠를 제공해 드론 기초 조작을 쉽게 학습할 수 있도록 유도했지만 교육생들이 실제 드론을 어떤 컨트롤러로 조작하는가에 대한 조사가 미흡했다. 이를 해결하기 위해서 필요한 학습 콘텐츠를 설계하고 교육생들이 소지한 드론 컨트롤러로 체험을 할 수 있도록 구현했다.

Nowadays, many graphic researchers are interested in 3D outdoor environment. They want to express more realistic natural background with natural phenomenon because computer hardware has become more powerful and increased a demand for a background of 3D natural environment in a content. Especially, e-sports contents and simulation contents with outdoor environment need more natural environment for a background than indoor contents. It is very important technology for a quality of 3D outdoor contents. We propose a software EMtool(Environment Making Tool) for authoring of natural environment for realistic contents. EMtool has been developed to depict relationship and interaction between natural phenomena and include methods for creating natural environment and natural objects. The proposed results are applied to real-time 3D contents such as 3D golf games and simulations for natural objects.

The popularization of smart phones changes the usage patterns of mobile communication from voice-centric to data-centric communication. The demand for wireless data communications is rapidly increasing, and thus the need for expanding infrastructure for mobile communication is also rapidly increasing. In this paper, we propose a scheme for reducing the cost for the mobile communication infrastructure by exploiting opportunistic networks in dissemination of multimedia contents. By using this scheme, the large portion of the cost for mobile communication infrastructure could be saved, and the need of users for multimedia contents could be also fulfilled. Our scheme is evaluated using agent-based simulations. The simulation results show that about 70% of mobile communication can be replaced with the data communication through opportunistic networks.
