From the past until now, political and economic relations among countries have been one of the most important issues among analysts and numerous studies have tried to analyze these relations from different theoretical perspectives. The dynamic system of games has introduced a new modeling method in the game theory. In this study, we use behavioral models (level- k) along with the dynamic system in games to model rational agent behavior. As an application, we study Russia- Norway economic and political relations (1970-2019). The dynamic system in games along with behavioral games theory can be used to predict the players behavior in the future.

E-sports에서 가장 흥행한 작품이라 볼 수 있는 스타크래프트, LOL과 같은 게임들을 포함하여 RTS 장르의 대부분의 게임들의 플레이 방식이 점점 획일화되어 지루함을 주기 시작하였다. 획일화되고 지루한 시스템 속에서 좀 더 변화를 주기 위해선 지금 충분히 발전하고 검증된 장르간의 조합을 통해 해소할 수 있다고 생각되어 새로운 게임 패러다임을 제시하고자 했다. 이를 위해 흥행한 게임 장르 중 RTS와 TCG라는 장르에 주목하여 이 두 장르의 동적인 특징과 정적인 특징을 융합해 새로운 패러다임을 제시하자 한다. 본 논문에서 제안하는 새로운 RTTC(Real-Time Trading Card) 장르의 게임 시스템은 게임의 동적 요소와 정적 요소를 퓨전한 새로운 형태의 게임 시스템을 말한다. 이 혼합된 장르는 실시간 대전이라는 RTS의 특징에 카드라는 랜덤성을 추가하면서 게임의 획일성을 최소화하여 게임을 하는 사람과 게임을 보는 사람 모두를 만족시킬 수 있는 게임의 새로운 패러다임이 될 수 있다.

Online games are the popular topic due to the increased total online game market volume nowadays. And many studies on online games are released. But most studies used the questionnaire method that reveals only section of the situation like a snapshot. For this reason, previous studies have a little limitation that does not show dynamical changing issues like a product life cycle and changes in customer's mind Because of this, we studied on online games with the system dynamic model which can show dynamic simulations to analysis time series data. We chose MMORPG (Massively Multi-play Online) RPG (Role Playing Game) in sort of online games because it has many absorbing factors and enthusiastic users. We designed the simulation model which analyzes the influences of update and CRM strategy on users. We put the game developer who is ready for updated version game and released that periodically and focused on dormant users who used to be enthusiastic about MMORPG. The simulation results showed that the update has positive influences on new users gathering and hold established users. And CRM strategies help to prevent dormant users from transferring to rivals by offering them re-absorbing factors. Through this study, we confirmed the importance of update on online games and the necessity of introducing CRM strategy in the online game market.

The aim of this paper is to model North Korea and USA relationship since past until now. To this end, we have used game theory. The weakness of the existing models is that they have a static nature and can't analyze the changes of processes, strategies and results. The dynamic system of strategic games of which we have used in this article is a proper method to solve this problem. We have shown that South Korea and China play an important role in resolving the crisis.

Research on the visual narrative impact of Unreal Engine's Lumen lighting system in games aims to delve into how Lumen's lighting technology plays a crucial role in game design and gameplay experience, thereby enhancing the visual storytelling of games. Lumen, Unreal Engine's dynamic global illumination solution, calculates lighting and shadows in real-time during gameplay, creating a more realistic and immersive environment. Analysis indicates that Lumen technology not only provides visually realistic and dynamic lighting effects but also significantly enriches the expressiveness and immersion of the game narrative through its changes in light and shadow.

The movements of the human body are difficult to capture owing to the complexity of the three-dimensional skeleton model and occlusion problems. In this paper, we propose a motion capture system that tracks dynamic human motions in real time. Without using external markers, the proposed system adopts multiple depth sensors (Microsoft Kinect) to overcome the occlusion and body rotation problems. To combine the joint data retrieved from the multiple sensors, our calibration process samples a point cloud from depth images and unifies the coordinate systems in point clouds into a single coordinate system via the iterative closest point method. Using noisy skeletal data from sensors, a posture reconstruction method is introduced to estimate the optimal joint positions for consistent motion generation. Based on the high tracking accuracy of the proposed system, we demonstrate that our system is applicable to various motion-based training programs in dance and Taekwondo.

In MMORPG, gamers can engage in a variety of activities with other players from all over the world. So, this kind of games has unprecedented heavy load. There are so many kind of method to balance the load of MMORPG. But. many of them are not adaptable to dynamic load variation. In this paper, we propose a dynamic map-partition method based on VML. By use of dynamic map-partition based on VML, we can easily adapt to dynamic load variation. And by changing VML. we can manage field servers within game system.

Collision is a brief dynamic event consisting of the close approach of two or more objects or particles resulting in an abrupt change of momentum or exchange of energy because of interaction. Collisions play very important role in computer graphics, computer games and animations fields. Collisions can supply active interaction between cyberspace and real world and give much interests for making nice games so reasonable collision detection algorithms are needed. Collision detection algorithms should satisfy being fast and accuracy. In this paper, we survey the 2D collision detection algorithms between geometric models. We present several methods and system available for collision detection.

Using video synthesis to depict flowing water is useful in virtual reality, computer games, digital movies and scientific computing. This paper presents a novel algorithm for synthesizing dynamic water scenes through a sample video based on a dynamic texture model. In the paper, we treat the video sample as a 2-D texture image. In order to obtain textons, we analyze the video sample automatically based on dynamic texture model. Then, we utilize a linear dynamic system (LDS) to describe the characteristics of each texton. Using these textons, we synthesize a new video for dynamic flowing water which is prolonged and non-fuzzy in vision. Compared with other classical methods, our method was tested to demonstrate the effectiveness and efficiency with several video samples.

본 논문에서는 서사의 핵심 자원인 NPC 및 다양한 월드 자원들을 가진 가상의 영속적 RPG 월드에서 NPC들이 창발적인 퀘스트를 지속적으로 생성할 수 있는지 실험을 통하여 검증하고자 한다. 이를 위해 가상의 RPG 월드 환경과 선행 연구들의 퀘스트 유형을 상정하여, NPC의 내적 욕구와 다른 자원의 발견 사건을 통해 퀘스트를 생성하는 실험을 하였다. NPC의 퀘스트 생성 의사결정은 욕구 충족정도, 재화 보유 그리고 상호 관계를 변수로 하였으며, 이들 변수는 퀘스트의 수행 결과에 따라 지속적으로 다음 퀘스트 생성에 영향을 주도록 하였다. 본 연구를 통하여 영속적 가상 월드에서 NPC자원들이 절차적 의사 결정 과정을 통하여 다양한 퀘스트를 지속적으로 양산할 수 있음을 보여주었다.
