Serious game played with a computer in accordance with specific rules, that uses entertainment to further government or corporate training, education, health, public policy, and strategic communication objectives. The main goal of a serious game is usually to train or educate users while giving them an enjoyable experience. Serous games are video games with serious purposes such as teaching or training and whose principal aim is education. The major characteristics of serious games involve pedagogy which are all of the activities that educate, train, or instruct the player. Other characteristics of serious games are that they use entertainment principles, creativity and technology to build games that carry out serious purposes. This study is to introduce a serious game for the military training and to describe the elements of game design for developing it.

Recently, in the Game industries, they are increasing to use of game engines to reduce the development cost of 3D content and software. In particular, Unreal Engine provides a blueprint visual scripting function that enables software production without programming (coding). Although High-end video content can be produced, the problem is that content development is complicated and requires advanced manpower. To solve this problem, we propose an optimized VR game context process. This is because 1) a Blueprint visual script is used, 2) VR games with various interactions can be produced, 3) Non-majors in the software field (or groups) can develop advanced content. In various related industries such as defense, medical care, manufacturing, and construction, we may easily develop any game content without programming with our refined VR rhythm action game development process. We expect to reduce the development cost with the process advantages in the game industries.

Real-time 360 VR (Virtual Reality) stereo image acquisition technique based on game engine was proposed. However, GPU (Graphics Processing Unit) resource is not fully utilized due to bottlenecks. In this paper, we propose an improved GPU scheduling technique to solve the bottleneck of the existing technique and measure the performance of the proposed technique using the sample games of the commercial game engine. As a result, proposed technique showed an improvement of performance up to 70% and usage of GPU resources more evenly compared existing technique.

Commercialized game engines help develop content and support various platforms, but there are performance differences depending on the function. In this paper, a VR video conferencing platform corresponding to source multi-use was implemented, and the connection delay time according to the type of game server engine and the number of platform users was measured. As a result of the measurement, the latency was the lowest at 22.146 msec when using the Amazon GameLift engine and with 2 users, and the latency was the highest at 27.007 msec when using the ProudNet engine and with 10 users.

A growing body of research has focused on the negative effects of Internet gaming. This issue has become an increased public health concern in Korea. However, little is known regarding the positive effect of Internet gaming and its etiology. This study examined the effects of gaming motivations on gaming behaviors based on self-determination theory. Specifically, we investigated the associations of intrinsic and extrinsic gaming motivations with adaptive and maladaptive game uses. A cross-sectional data collected from a sample of 3,000 young adults using 2016 Korean Video Gaming Survey was analyzed. Measurement model analysis and structural equation modeling were conducted as primary analyses. The findings highlight the different effects of intrinsic and extrinsic motivations on gaming behaviors, such as adaptive and maladaptive game uses. Intrinsic motivations, such as experience-seeking and achievement-seeking, were associated with adaptive game use. Meanwhile, extrinsic motivations, such as sensation-seeking and monetary reward-seeking, were associated with maladaptive game use. The findings provide a better understanding of video gaming in light of both adaptive and maladaptive game uses. The implications for practice and policy were discussed.

The difficulty of the game is closely related to the fun of the game. However, it is not easy to determine the appropriate level of difficulty of the game. In most cases, human playtesting is required. But even so, it is still hard to quantitatively evaluate difficulty of the game. Thus, if we perform quantitative evaluation of the difficulty automatically it will be very helpful in game developments. In this paper, we use a path finding algorithm to evaluate difficulty of exploration in a game level. Exploration is a basic attribute in common video games and it represents the overall difficulty of the game level. We also optimize the proposed evaluation algorithm by using previous exploration histories when available area in an game level is dynamically expanded and the new search is required.

The Unreal Engine is a free game engine developed by Epic Games. In this paper, we propose a First Person Shooter (FPS) game development using free Unreal Development Kit. The merit of Unreal engine provide a hight degree of portability, and it is a tool used by many game developers today, supporting a multitude of platforms on personal computers and many video game consoles with free toolkit. But it is required high-performance PC to develop game. This toolkit doe s not high-quality computer programming skill, just possible to develop FPS game easily.

Objectives : To help Oriental medicine clinical studies for the game addiction treatment, this study analyzed the tendency of research into game addiction recently published in PubMed Methods : This study analyzed 13 research papers on game addictionpublished in PubMed over the past 3 years. It measured annually and for each country the number of papers published, the number of subject, the period of research, the method of study, the objective of study, and intervision, respectively and intervision, and the result of study overall Results : There were research papers concerning internet & online game, computer game, gambling, video game. The subject of study were adolescents, high school students, children, young adult. there are many reaearch papers on negative results of games. there are research papers of the mechanism or factors of game addiction. Conclusions : Recent research subject of game addiction were mostly the defect of game.

In this paper, we propose a synchronized playback method of 3D reference model and video by extracting golf swing information from learner's golf video to precisely compare and analyze each motion in each position and time in the golf swing, and present the implementation result. In order to synchronize the 3D model with the learner's swing video, the learner's golf swing movie is first photographed and relative time information is extracted from the photographed video according to the position of the golf club from the address posture to the finishing posture. Through applying time information from learners' swing video to a 3D reference model that rigs the motion information of a pro-golfer's captured swing motion at 120 frames per second through high-quality motion capture equipment into a 3D model and by synchronizing the 3D reference model with the learner's swing video, the learner can correct or learn his / her posture by precisely comparing his or her posture with the reference model at each position of the golf swing. Synchronized playback can be used to improve the functionality of manually adjusting system for comparing and analyzing the reference model and learner's golf swing. Except for the part where the image processing technology that detects each position of the golf posture is applied, It is expected that the method of automatically extracting the time information of each location from the video and of synchronized playback can be extended to general life sports field.

최근에 들어서 VR, AR 등 '현실'을 기반으로 하는 장르가 주목을 받고 있다. 그 중에서도 ARG 장르가 존재하는데, 우리가 살고 있는 현실 세계에서 가상의 이야기들을 마치 실존하는 것처럼 꾸며 놓고 관객 혹은 플레이어들이 스스로 단서를 찾아 스토리의 끝을 매듭짓는 것이 목표인 장르이다. ARG 장르는 그 자체가 게임이 될 수 있고, 메인 게임 장르의 세부적인 요인으로 작용할 수도 있는 매력적인 장르이다. 본 논문에서는 ARG 게임에 대한 세부적인 분석과 인식 조사를 진행하여, 그 결과를 바탕으로 해당 장르를 보편화 시킬 수 있는 방법을 제시한다.
