When a company provides new games or games with a small number of users, it is convenient to provide the game service in which those games are placed in a server cluster instead of a separate server for an individual game. This paper proposes a method for placing games in a cluster of servers with the same capacities. The method reduces the load imbalance among servers and minimizes the rejection ratio of user requests. We expect that the proposed method is useful for determining the server operation factors such as the number of servers, the number of games for a server, etc. To our survey, little research has been published on game placement on a cluster of game servers.

Outdoor ads such as billboards, banners or posters frequently appears in street maps of FPS games. In this paper, we propose a method for the automatic placement of outdoor advertising in the city area of FPS games. Outdoor ads are from real world products or enterprises and they are managed in a server computer. If the ads data are updated, the advertisements are automatically placed again without modifying source codes. When placing ads, we utilize the real world location of the game player regarding commercial spheres of ads and service types of real world shops. We evaluate priority scores for the available ads based on the collected real world properties and higher priority ads are preferentially placed on the map. The proposed ad placement method makes the game players feel affinity for the placed ads and also it increases the advertising effect.

Providing various levels of difficulty of game play is one of important considerations in game development. In this paper, we propose a method for obtaining the challenges that will be placed on the track of an one-player car driving game. Herein challenges denote obstacles on the track, and the level of difficulty is represented by an estimated time needed for driving one lap of the track. In the proposed method, the problem for finding challenge placement is modeled as an IP(Integer Programming) one, and then LP relaxation and Simultaneous Annealing are employed to find a solution. To the experiment with the proposed method, we can obtain challenge placements to approximately meet given target driving times. Also, after practically driving on the track where those obtained challenges are being placed, it is seen that the average driving times approximate the target driving times of those challenge placements. Our method can allow game play with various levels of difficulty so that the users' interest and the level of immerse are expected to be raised.

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.

This study is to examine relationship between immersiveness aspect and the recognition of garners who are exposed to PPL (Product Placement Advertisement) in online game. The frequency of exposure, the placement type of PPL, the perception under the threshold of consciousness and the interest at the product and knowledge about PPL have been widely known as the factors of effectiveness in PPL advertising. In this study, 'immersiveness' is newly introduced to investigate the effectiveness of PPL advertising due to the unique characteristics of game which easily leads to immersion. Control group is exposed to movie clip and experimental group to lacing online game. In conclusion, the deep immersion has reduced the perception level of user on PPL except the variable of PPL placement. This study suggests that how to design the PPL placement in game for enhancing marketing effect is all the more vital, in spite of the result that the player in high immersion cannot distinguish different images.

An SLBM (submarine-launched ballistic missile) seriously threatens the national security due to its stealthiness that makes it difficult to detect in advance. We consider a destroyer deployment optimization problem for effectively detecting an SLBM. An optimization model is based on the two-person zero-sum game in which an adversary determines the firing and arriving places with an appropriate trajectory that provides a low detection probability, and we establish a destroyer deployment plan that guarantees the possibly highest detection probability. The proposed two-person zero-sum game model can be solved with the corresponding linear programming model, and we perform computational studies with a randomly generated area and scenario and show the optimal mixed strategies for both the players in the game.

맵에디터(map editor)란 게임에 사용될 게임환경을 저작하는 도구로서 게임의 무대가 되는 지형을 생성하고, 게임에 사용되는 다양한 건물이나 주인공, 몬스터 등을 객체를 배치하는 등 게임 환경의 변화를 눈으로 보면서 손쉽게 저작할 수 있도록 한다. 뿐만 아니라 게임 객체 혹은 지형의 여러가지 속성을 설정해 게임에 그 값을 반영토록 하는 기능을 제공하기도 한다.

본 논문에서는 Kinect 센서 기반의 카드 매칭 게임을 설계하고 구현한다. 이 게임은 유아용 카드 매칭 게임으로 카드 뒷면을 화면에 배치시키고 무작위로 앞면의 그림을 보여준다. 플레이어는 앞면의 그림을 위치별로 기억하여 같은 짝의 그림을 선택하여 맞춘다. 다른 짝을 매칭 할 경우 다시 뒷면으로 뒤집히고 같은 짝을 매칭 할 경우는 해당 그림의 영어 단어를 팝업시킨다. 예를 들어 토끼 그림의 짝을 매칭 할 경우 RABBIT이란 단어를 팝업 시킨다. 그리고 플레이어는 RABBIT이란 단어를 발음하면 Kinect는 음성을 인식하여 팝업된 창을 종료하고, 게임을 계속 진행한다. 게임은 화면에 배치시키는 카드를 $2{\times}2$부터 시작하여 난이도 별로 증가 시키고 스테이지 별로 콘텐츠를 나눠 영유아들이 재미있게 게임을 즐기면서 영어 단어를 학습할 수 있는 게임이다.

게임 진행모듈이란 개별 엔진을 유기적으로 통합하고, 각종 데이터를 효율적으로 관리하며, 기획을 충실히 반영해 콘텐츠를 개발하는 데에 필요한 모듈을 말한다. 렌더링 엔진, 애니메이션 엔진 등 개별 엔진과 기획서가 충실히 준비됐다고 하더라도 그것을 이용해 성공적인 게임 콘텐츠를 만들기 위해서는 많은 추가 작업이 필요하다. 이것을 요리에 비유하면 바로 이전까지는 요리를 만들 재료만 준비된 것이라고 볼 수 있다. 이 재료들을 알맞게 배합하고, 순서에 따라 조리를 한 다음 보기 좋게 식탁에 배치해야 하는 일이 지금부터 해야 할일이다. 이런 일을 하는 것이 게임 진행 모듈이다. 이번 호에서는 게임 진행 모듈을 엔진의 통합과 게임 객체의 관리로 나누어서 설명하겠다.

The composition of the 'The Game Story' should reflect the game play and development environment. To do that, I borrowed a coordinate format called 'Spatio-temporal Coordinate Array' that was not based on text-based storytelling. I wanted to create a way for the story to describe relationship between 'action' based on time and 'object' based on space. One way to do this was to analyze the concepts using a mystery game in which Spatio-temporal Array is a large role in user's decision-making. As a result, I found that the method -Spatio-temporal coordinates- was an editor containing game play, and a setting tool capable of being used as a conceptual diagram.
