HCI (Human-Computer Interaction) 연구 방법론을 통한 게임 평가들은 사용성 혹은 몰입도 등을 사용하여, 게임 사용자들이 flow experience 를 가질 수 있도록 하는 다양한 게임디자인 방법론을 제안하였다. 하지만 이와는 다르게 일련의 학자들은 게임에 대한 평가가 단순히 게임 안에서 이루어지는 사용성 혹은 몰입도 평가를 넘어서, 사회-기술적 환경 (Sociotechnical environment) 안에서 심리 혹은 행동양식으로 평가가 이루어져야 한다고 주장한다. 이러한 배경하에 본 연구는 심리-행동양식을 고려한 새로운 게임 평가 가이드라인을 제공하고자 한다. 본 논문은 세가지 실험조건을 토대로 공격성향환기 (Arousal aggression) 평가와 공격성 측정게임을 통한 공격행동 (Physical aggression)을 측정하여, 게임에 대한 새로운 사용성 평가 프레임워크를 제안한다. Prior evaluation frameworks for games are mostly grounded on their easeof-use and engagement levels, and how these two factors are able to present flow experience or pleasant-to-use. However, some critics on this approach claimed this traditional usability approach would not uncover the core part of gaming experience, such as player's psychological and behavioural attitudes, arising from its socialtechnical environment of playing games. The present study empirically demonstrated a new evaluation framework for gaming experience in conjunction with two extra dimensions, i.e., physical aggression and arousal aggression.

Voronoi diagrams are useful for reasoning spatial properties among particles. In particular, the Voronoi diagram of circles in 2D is important on its own and has many applications. And also it is meaningful for extending to that of spheres in 3D. In this paper, we propose a new algorithm for construction of Voronoi diagram of circles. This algorithm constructs the Voronoi diagram by adding a new circle to the already constructed one and then changing the topology influenced by the new circle. The approach using topology uses logical computations instead of numerical computations. That reduces the number of numerical errors.

Geometric properties are critical for the function of molecules consisting of atoms with different radii which are usually modeled as spheres in 3D. “Molecular Geometry” is a theoretical framework of computational understanding of the geometry of molecules in the claim that most molecular structure problems can be effectively and efficiently facilitated by the “geometrization” of the problem into that among spheres in 3D whose solution can be easily found via “geometry kernel”. In this paper, we report BULL!, the molecular geometry engine based on the Voronoi diagram of spheres, the quasi-triangulation, and the beta-complex. Being a program implemented in C++, application programmers can simply call API-functions of BULL! to create application programs correctly, efficiently, and conveniently. The BULL! is designed compatibly so that application programs are completely independent of future modifications and improvements. The BULL! engine will be freely available from the Voronoi Diagram Research Center at Hanyang University.
