국내 게임산업현장에서 게임시스템 기획은 기획자가 게임컨셉을 만족하는 게임플레이가 이루 어지는 게임메카닉스 시스템을 데이터구조적 설계방법으로 creative design 작업관점에서 초 기적으로 설계하는 작업이다. 그러나 프로그래머는 구현을 위해 기획내용을 바탕으로 게임시 스템을 객체지향적 방법으로 engineering design 작업관점에서 설계한다. 이러한 작업방식은 기 획자와 프로그래머 사이에 의사소통 과정에서 다양한 오류들과 작업결과물의 미스매칭 오류들 의 발생가능성이 높다. 이 문제를 해결하기 위해, 본 논문에서는 기획자가 객체지향적 설계방법 으로 게임시스템을 기획하는 방법을 제안하였다. 제안하는 방법은 객체지향적 SW 개발 가이 드라인인 GRAPPLE을 기반으로 기획자의 게임시스템 기획에 적합하도록 커스터마이징한 것이 다. 본 논문에서 제안한 게임시스템 기획방법의 효용성을 조사하기 위해 국내 게임산업체에 근 무하는 게임시스템 기획자 10명을 대상으로 설문조사하였다. 설문 조사결과는 거의 모든 대상 자들이 제안한 방법의 효용성이 ‘조금 이상’ 있음으로 나타났다.

DEM(Digital Elevation Model) 크기의 변화에 따라 특정 지역에 많은 규격의 수문 데이터가 존재할 수 있기 때문에, 어느 지역, 어느 기상 데이터에도 작동할 수 있는 수문 모형의 개발이 절실히 필요하게 되었다. 이와 같은 필요성을 설명하기 위해서 객체지향(object-oriented)적인 프로그래밍 기술을 적용한 GHISMO(Geographic and Hydrologic Information System Modeling Objects)라는 수문모형(hydrologic model)을 개발하였다. GHISMO의 가장 핵심적인 수문학적 접근방법은 저류-배출(storage-release)과 지표면 유효 강수량을 구하기 위하여 SCS curve number 방법을 사용한 것이다. 이 연구에서 수문모형의 모의실험 결과를 제공할 것이다.

In order to cope with the changes of container terminal situation in these days, many simulation studies for container terminal have been accomplished. But previous simulation studies using simulation language have limitations in model representation and difficulties in modeling of large scaled container terminal system. To make these problems better, this paper addresses an object-oriented simulation of container terminal system using a DEVS formalism. The DEVS(Discrete Event System Specification) formalism, developed by Zeigler, supports specification of discrete event system in a hierarchical and modular manner. The formalism provides a mathematical basis for studying discrete event systems with better understood and sounder semantics. In a step of system modeling, a DEVS formalism aims at the exact system modeling that has a basis of semantics and utilizing the object-oriented manner can flexibly cope with the changes of system environment. In this study a model is developed and verified through the simulation of some alternatives.

The purpose of this study is to develop a rural stream environment management system (RUSEMS) using Object Oriented Programming (OOP). In this study, the management goals of RUSEMS were conceptualized and systemized. The objects which required in RUSEMS were developed, then the method and the attribute of the objects were also devised, and the hierarchy of the objects was constructed by OMT method in this study. The results of the system application showed that RUSEMS was enable to manage, to analyze, and to offer the information about the monitoring, analyzing of the rural stream pollution, and managing pollution source of the watershed and the rural stream environment management for the friendly water space.

The production process of the compound-curved hull plates includes hull design, definition, fairing, modeling, lofting, cutting, and forming in sequence. Traditional fabrication methods and shop environment caused low level to productivity in medium and small sized shipyards. The most effective solution to solve those problems is to rationalize the layout of facilities. For the well-balanced development of domestic shipbuilding industry, it is urgently required to reduce the gap between modernized large sized shipyards and traditional small and medium sized shipyards in production technologies and efficiencies. For the efficient and accurate hull piece forming, all information from design to forming should be clarified and organized in a systematic manner. Thus, management of the information plays an important role in the computerized and automated of hull piece forming. The object of this paper is to survey the status of the field, to find out the feasibility and to introduce a draft of hull piece fabrication line for small and medium sized shipyards. The development of required system follows the object oriented technology to extend to simulation based system for carrying out physical product flow and facilities layout analysis. It is feasible to operate such a modernized facility for a group of small and medium shipyards who are unable to have each of their own facility because of its large amount of initial investment and insufficient work load.

The purpose of this study is to develop the data structure for querying database of a rural house design. It is necessary, for developing the data structure, to define items of rural houses and to study about the processing of the data. The classifications of rural houses can be differed in the subjective opinion for computerization. In this study, items of classified rural houses can be expressed numerically, like size and number of room. The user who has insufficient knowledge about house is hard to input items fit personal taste. The querying algorithm was developed using the relationship of items and functions of house. Functions of house mean family life-style and how they use space.
