기존 객체지향 개발 방식과 컴포넌트 개발 방식에서의 재사용성 문제는 모바일 개발에서도 해결해야하는 문제이다. 모바일 어플리케이션에서 기능을 변경하는 것은 모바일 어플리케이션 전체를 업그레이드 할 필요가 있는데, 이는 모바일 어플리케이션이 디바이스 내의 다른 어플리케이션들과 연계된 서비스와의 문제를 발생시킨다. 따라서 모바일 어플리케이션 내에 변경 가능성이 있는 기능들에 대해 재사용성을 고려하여 개발되어야 한다. 본 논문에서는 모바일 어플리케이션이 다양한 요구사항에 대해 재사용성을 높일 수 있는 커스터마이제이션 기법을 제안한다. 가변성 중에 데이터 기반의 가변성을 적용하여 변경을 요구하는 기능에 대해 자동으로 변경될 수 있는 자가적응 커스터마이제이션 기법을 제시한다.

Uninterrupted power supply has become indispensable during the maintenance task of active electric power lines as a result of today's highly information-oriented society and increasing demand of electric utilities. The maintenance task has the risk of electric shock and the danger of falling from high place. Therefore it is necessary to realize an autonomous robot system. In order to realize these tasks autonomously, the three dimensional position of target object such as electric line and the stand of insulator must be recognized accurately and rapidly. The approaching of an insulator and the wrenching of a nut task is selected as the typical task of the maintenance of active electric power distribution lines in this paper. Image recognition by multilayer neural network and optimal target position calculation method are newly proposed in order to recognize the center 3 dimensional position of the bolt hole in the stand of insulator. By the proposed image recognition method, it is proved that the center 3 dimensional position of the bolt hole can be recognized rapidly and accurately without regard to the pose of the stand of insulator. Finally the approaching and wrenching task is automatically realized using 6-link electro-hydraulic manipulators.

본 논문은 객체지향 프로그램(OOP)을 사용하여 광양제철소 전력계통의 과도안정도를 모의한다. OOP는 절차식 프로그램보다 유연한 방법으로서 동적인 시스템의 모의에 여러 가지 장점이 있다. 시스템의 변화가 있으면 프로그램 전체을 수정하는 대신 필요한 부분만을 수정하면 되므로, 프로그램의 유지 및 보수가 매우 용이하다. 본 논문에서는 OOP를 이용하여 동적인 시스템의 해석을 위한 유연한 방법을 제시하였다. 시스템을 직접 사용자가 그려서 전력조류계산과 동적 안정도를 모의할 수 있는 사용자 인터페이스를 구현하여 17기의 동기발전기와 25기의 동기전동기로 구성되는 광양제철소 전력계통의 동적 안정도 해석에 적용하였다.

This study developed a settlement environment diagnostic indices (SEDI) of rural villages which can apply to analyze variable conditions of villages having development projects. The index consists of 5 diagnostic areas (first level) with 13 items (second level), including detail indices of 40 criteria (third level) defined by specialists' brainstorming process. In order to develop the index system, object-oriented approach was used to extract the 5 diagnostic areas (infra-basic settlement facility, life condition & environmental resources, industry & economic infrastructure, community, and residents) from rural villages. For the 40 criteria, it was introduced a quantification method that all villages have absolute values in national level, not relative value between villages within an unit area. The diagnostic diagram and table were developed to evaluate the villages compositively. The developed SEDI was applied to study areas, 56 villages in 2 subdivision areas of county, located on county of Keumsan. Applicability of the index system, database system should be developed with the surveying method of data in village level.

The insertion task of an electric line into a sleeve is selected as the typical task of the maintenance of active electric power distribution lines in this paper. A modified hough transform is applied to the recognition of the center of electric line and optimal target position calculation method is newly derived in order to recognize the center 3 dimensional position of the electric line. By the proposed method, it is proved that the center position of the electric line can be recognized without respect to the noise of image and the shape of electric lines and the insertion task of an electric tine is realized.

Under the environment of various network and multimedia, various theories are studied to make utilize digital story telling authoring. In the era of digital convergence and ubiquitous information, they want to send information with additional emotional information which is preferred constructive sending method. Digital storytelling refers to a unified technology for narrative structure with the picture and act. If engraft with particular research field, It will make interactive or linear story structure. These structures have problems that they are mismanaging on the result and they are not integrated systemization in each society. Because those are designing storytelling without development process and they are focusing on web distribution. This thesis is design using the object-oriented methodology of component-based design methodology, This thesis create digital storytelling and design metadata for contents management. In the requirement phase, subject and predicate part are extracted from the narrative structure of the story and restructure an organization. We explain by giving specific examples "kongjwi and patjwi" story as a case study.

In most dynamic manufacturing environments today, systems and processes are constantly changing. Simulation tools are required that can accurately model the system in detail, but still be easy to use, and allow rapid model redevelopment to react quickly for system changes. An object-oriented simulation modeling environment is presented to provide flexible modeling capabilities for simulation. Also, when simulating an assembly system, a large number of factors must be considered. Because of such complexities, simulation has been used as the primary method in designing, planning and analyzing. In this paper, the dynamic manufacturing environment is discussed for the assembly system. Also, an application method of simulation tools is presented with the experimental data from the automobile manufacturing shop to improve the productivity effectively.

As various methodologies for business process analysis and design have been conducted in many organizations by their own ways, those methodologies are not compatible each other. In order to reduce the cost of analysis for organizations. some mapping methods between different methodologies need to be developed. UMM(UN/CEFACT Modeling Methodology) that has an object-oriented point of view. can overcome the limits of existing bottom-up approaches and make it reasonable. It also simplifies the business and administrative procedures. IDEF( Integrated Definition Language) with a structural point of view that has been widely used as a system analysis and design method, needs to be mapped to UMM in order to reuse the existing IDEF models. In this study, we propose a guideline that deals with procedures of utilizing IDEF models from which we want to derive the UMM models for developing an electronic commerce system including electronic documents exchange. By comparing IDEF and UMM, we analyze the differences between those two methodologies. Based on these differences. we suggest the basic strategies for mapping method from IDEF to UMM. We also propose a mapping guideline that can make UMM results from the modeling results of IDEF. We can take an advantage of the existing IDEF analysis design results when we adopt UMM methodology for electronic business system. Many analysts who are familiar with the IDEF methodology can develop UMM work-flow by utilizing their existing results and skills.
