In computer games, the level design and balance of characters are the key features for developing interesting games. Level designers make decision to change the parameters and opponent behaviors in order to avoid the player getting extremely frustrated with the improper level. Generally, opponent behavior is defined by static script, this causes the games to have static difficulty level and static environment. Therefore, it is difficult to keep track of the user playing interest, because a player can easily adapt to changeless repetition. In this paper, we propose a dynamic scripting method that able to maintain the level designers' intention where user enjoys the game by adjusting the opponent behavior while playing the game. The player's countermeasure pattern for dynamic level design is modeled using a Gaussian Mixture Model (GMM). The proposed method is applied to a shooting game, and the experimental results maintain the degree of interest intended by the level designer.

The objective of this research is to discover the rule of gameplay related to the task interdependence to analyse the behavior pattern of social gameplay. Previous literatures related to the gameplay were reviewed and game which was suitable for the gameplay of the task interdependence was selected. A party-play includes a team of five people in the experiment during the gameplay with think-aloud method and video/audio data about action protocol and verbal report were collected. The video observation and protocol analysis were conducted to analyse data. The objective coding scheme were developed from consolidated sequence model task analysis. The player's behavior was analysed. The result was revealed that four rules and four modified rules were included into the total eight behavior pattern. A behavior graph integrated with five gameplay was written. The excellent cooperative spot and error and failure place could be identified. The social gameplay behavior graph is expected to be the key practical design guideline on whether the level design and balance design are proper.

Accurate information on players, namely player analytics is one of the key factors in a game development environment where a scientific approach to user-oriented game analysis is in the spotlight. This study is intended to examine effects of relations between choke point types and cover pattern properties on level difficulties in FPS games. As for FPS games, interaction between players' behaviors and game levels is higher compared to other genres and choke point types as well as cover pattern properties are key factors of level design. Choke point is the main crossroad that must to pass for achieving the goal and Cover Pattern is the type of object on the level except buildings. Two elements directly or indirectly affect the level of difficulty. This study analyzed 10 types of representative FPS gameplays to classify choke point types and assigned 4 types of cover pattern properties to organize 16 target levels for the experiment. In addition, this study collected and analyzed players' 800 behavior data (video clips) from 5 repetitive plays performed by 10 players. In conclusion, analytical results obtained from the empirical study will contribute to realizing systematic game level development by providing specific information for a game level design phase. The findings are also meaningful in that they suggest efficient and effective methods of utilizing the existing academic study results for industrial applications.

The purpose of this research is to provide the rationality of placement of game objects using the space analysis for game map so that the game designers can find out the proper position for each object in the map. The significance of this research is beyond the limitations of the existing research using Space Syntax theory is confined to the analysis of the behavior of players in the map, this research suggest the method of the efficient placement of game objects in level design step. This paper as the worth of the industry is expected to be able to reduce the repetitive tasks that may occur during game level design steps. Through this, it is also expected by reducing game development period and development costs in accordance with the reasonable placement of game objects.

시스템 레벨 PCB(Printed Circuit Board) 디자인은 최종적인 시스템 특성에 정확한 정보를 갖지 못하는 디자인 결정을 하기 위해 여러 가지 정보가 필요하다. 또한 분할 할 때 분할 시간과 방법은 매우 중요하고 합성 결과의 특성은 교환(tradeoffs)과 디자인 결정에 매우 민감하다. 그러므로 만일 디자인이 합성되고 단일 보드로 디자인된다 할지라도 후에 다중 보드로 분할 될 수 있다. 따라서 본 논문에서는 PCB회로 디자인의 제약구동 방법중 off-critical-path 분할기법을 사용한 휴리스틱(heuristic) 방법을 제안했고 교환 그래프 착색 알고리즘을 제안했다.

In the stealth game design, level designers are to develop many interesting game environments with a variety of difficulties. J. Tremblay and his co-authors developed a Unity-based level design tool to help and automate this process. Given a map, if the designer inputs several game factors such as guard paths and velocities, their vision, and the player's initial and goal positions, then the tool visualizes simulation results including (clustered) possible paths a player could take to avoid detection. Thus with the help of this tool, the designer can ensure in realtime if the current game factors result in the intended difficulties and players paths, and if necessary adjust the factors. In this note, we present our improvement on this tool in two aspects. First, we integrate a function that if the designer inputs some vertices in the map, then the tool systematically generates and suggests interesting guard paths containing these vertices of various difficulties, which enhances its convenience and usefulness as a tool. Second, we replace the collision-detection function and the RRT-based (player) path generation function, by our new collision-check function and a Delaunay roadmap-based path generation function, which remarkably improves the simulation process in time-efficiency.

This paper is designed to make a research into the process of the formation and introduction of design management system necessary for the strategic utilization of design at a management love on the part of domestic small business. This paper is limited to the study of the general problems ralated to the design management of the domestic small business companies producing consumer goods. 1 made an examination of the necessity of the introduction of design management and of the necessity of design development in connection with the administrative features of small business, identifying the actual condition of design by the small business and discussing the actual situation of design management and tasks to tackle. lastly, 1 made a suggestion of the process, whose aim lies In the inside establishment of the design management system deemed desirable for the domestic companies. 1 have come to the following conclusions. First, small business should make use of design development so as to keep their competitiveness and to enhance their administrative features. Second,. design can serve as a means for making a speedy response in the companies'differentiation strategies arid strategies for markets with a lot of opportunities. Third, the utilization of design at an administrative love on the part of the small business works in the light of enterprise communications, organizations, business and marketing and so on. Fourth, the majority of small business are weak when it comes to organization, manpower and environment in relation to design. So it is necessary to introduce and construct the design management system. Fifth, the managers of the small business should first of all take a strong interest in and have a renewed understanding of the importance of design. I made a suggestion that the small business should carry out a process constructing the design-management system based on the design organization and manpower, but stopped short of confirming my suggestion in a corroborative way.

본 논문에서는 $0.35{\mu}m$ CMOS 공정을 이용하여 2.5 Gbps로 동작하는 광 송수신기를 설계하였다. 광 송수신기의 구성을 보자면, 전기 신호를 빛 신호로 전환하여 주는 레이저 다이오드(LD) 구동부와 레이저 다이오드에서 나오는 빛 신호를 수신하여 이를 다시 전기 신호로 바꿔주는 포토 다이오드(PD) 구동 부분으로 구성된다. LD 구동부는 LD의 문턱전류 이상을 공급하는 바이어스 부분과 신호레벨의 모듈레이션 전류를 공급하는 부분으로 구성된다. 디자인된 송신기는 바이어스 전류를 10 mA 정도 공급하여주며, 모듈레이션 전류를 15 mA 정도 공급한다. 수신기는 current decision 부분과 output buffer 부분으로 구성되어 PD로부터 나오는 전류를 다시 디지털 레벨의 전압신호로 바꾸어 주며 디자인된 수신기는 넓은 동작 영역을 가진다.

본 논문에서는 컴퓨터 게임공간의 레벨디자인을 기반으로 3D 공간에서 설계될 수 있는 트랩 유형을 제시하였다. 트랩은 게임 내의 장애물로서 3D 공간에서의 X, Y, Z 축으로의 이동방향, 고정, 운동, 회전, 스케일의 트랩 자체의 상태, 일회성, 반복, 순환의 작동타입 등의 요소를 바탕으로 표현된다. 트랩의 상태를 기준으로 작동 타입과 이동방향의 경우의 수를 조합한 결과 28가지의 트랩 유형이 도출되었다. 그리고 도출해낸 28가지의 트랩 유형이 실질적으로 게임공간에 적용되어 쓰이고 있는지 알아보기 위해 발리언트와 트라인 게임을 대상으로 트랩 유형을 살펴보았다.
