본 연구는 비즈니스 프로세스 리엔지니어링(Business Process Reengineering : BPR)의 분야에서 제기되고 있는 여러 가지 지침들을 종합.분석하였다. BPR 구축을 위한 단계를 분석(Analysis), 재설계(Redesign), 실행 (Implementation)으로 구분하여 각 단계별 지침들을 분석하였으며, 이러한 지침들이 조직구성요소중 어떤 요소에 영향을 미치는지를 분석하였다. 또한 각 단계의 지침들이 비즈니스 프로세스 리엔지니어링을 통하여 개선하고자 하는 성과 측정의 주요 요소인 품질(Quality), 비용(Cost), 속도(Speed), 서비 스(Service)의 측면에서 어떤 요소에 영향을 미치는지를 파악하였다. 이를 통 하여 BPR 구축의 기본적인 틀과 구조적 지침을 제시하고 있으며, 향후의 실 제적 적용 및 연구들이 나아가야 갈 방향을 제시하고 있다. 본 연구를 통하 여 기존의 연구에 대한 현황과 한계를 발견하였다. 첫째, 기존의 많은 연구 들은 BPR의 재설계 측면을 위주로 한 연구이며, 구체적이고 실천적인 지침 들을 제시하지 못하고 있다. 둘째, 실행단계에서는 주로 추상적인 지침들을 제시하고 있다. 셋째, 재설계 단계에서는 조직의 문화적인 측면이 별로 고려 되지 않고 있다. 넷째, 성과 측정의 관점에서 볼때 BPR 지침들은 특히 비용 절감을 위한 목표를 달성할 수 있는 지침들의 제시가 부족한 실정이다. 또한 조직환경, 조직구조, 조직문화와 같은 조직의 특수한 상황에 적합한 연구가 아닌 일반적인 지침들만을 제시하고 있어 BPR을 추진하는 조직 및 기업에 서 그 지침들의 효과가 매우 제한된다.

This study concerned the interoperability between the structural-analysis model and the default detail model in steel structures available for the structural-design process based on BIM. The purpose of the study was to develop an interface module that can perform data conversion between the analysis and design applications and the BIM applications, through the dotnet frame work development environment using OpenAPI provided by the BIM application vendor. The direct-link method was applied for BIM interoperability. A basic-frame model for detail design and modeling was created from the structural-analysis model to verify if the application was developed. Finally, the proposed process was compared with the existing process to verify the efficiency of the former.

Mobile Devices, which are developed with the fast growing of the Internet, have flexible internet accessibility and can access the network anywere so that they can execute software applications. However, it is very challenging to deploy highly complex applications on mobile devices since they have limited resources. To overcome the limitation, researches on applying a concept of services to mobile applications have been proposed. Android is one of the popular mobile platforms and is designed to effectively execute mobile applications on the mobile devices having limited resources. Since service-based Android applications, which adopt a concept of services and Android platform, invoke remote services and are built with Android-specific components, they are much different from traditional software applications. Consequently, it is not straightforward to apply object-oriented (OO) analysis and design methods to developing service-based Android applications, although they have been frequently applied to developing traditional applications. In this paper, we present a process to develop service-based Android mobile applications, which extends a traditional OO development process. First, we raise design issues to be considered in developing service-based Android applications. Then, to solve the issues, we present detailed guidelines for essential phases of OO-based development process that are customized to service-based Android applications. Finally, to show applicability of the process, we perform a case study. The proposed design process is effectively utilized as a set of guidelines to develop service-based Android applications more systematically and effectively.

For safety-critical systems including railways, there has been a growing need for effective and systematic safety management processes. The outcomes of efforts in this area are international safety standards, such as IEC 61508, 62278, and ISO 26262. One of the principal activities in the safety process is hazard analysis. For this reason, considerable efforts have been directed toward methods of hazard analysis. On the other hand, the hazard analysis methods reported thus far appear to be unclear in terms of their relationship with the system design process. In addition, in some cases, the methods appear to rely heavily on information regarding the hardware and software components, the number of which is increasing. These aspects can become troublesome when design changes are necessary. To improve the situation, in this paper, hazard analysis was carried out using the result of functional analysis early in the concept development stage for a safety-critical system design. Because hazard analysis is carried out at the system level and the result is then used to develop the safety requirements, improvements can be expected in terms of the development time and cost when design changes are required due to changes in the requirements. As a case study, the generation of safety requirements for the development of light rail transit stations is presented.

To formally describe business process, many business process languages have been so far specified with different origins and goals such as XPDL, BPML and BPELAWS. Especially, XPDL proposed by WfMC has been widely used in various business process environments for a long time. On the other hand, the necessity of a standard graphical notation for a business process may create BPMN driven by BPMI. Because BPMN is composed of graphical constructs which can be used to graphically depict business process, BPMN-formed business processes should ultimately be converted to their corresponding semantically equivalent business process language(XPDL). Then, the business process languages can be consequently executed by business process engines. In this paper, we proposed a transformation mechanism from BPMN to XPDL for a business process. By this paper, We minimized the difference between process designers and process execution modules as reducing the gap of semantics between BPMN and XPDL.

GIS도 다른 정보시스템과 마찬가지로 복잡화, 대형화, 전략정보시스템화로 발전해 가면서 개발방식 체계화가 요구되었다. 그러므로 계획에서부터 철저한 사용자의 요구사항의 분석과 설계가 요구되었으며 결국 GIS 개발방법론 적용의 필요성이 대두되기 시작하였다. GIS 개발방법론은 기존의 정보시스템 개발방법론에 빠져있는 공간정보 구축 및 검증절차를 다루기 위한 계획 및 절차의 미비점을 보완하고 여러 GIS 특성을 반영하여 프로젝트 수행시 보다 유용성 있는 성과물을 산출할 수 있도록 하여야 한다. 본 연구에서는 GIS 개발방법론을 도출하기 위한 기반연구로서 새로운 개발방법론을 창출하기보다는 기존의 정보시스템 개발방법론에서 GIS의 특성을 설명할 수 없는 부분의 프로세스를 도출하고 이를 중심으로 한 GIS 개발방법론의 기본 프로세스를 제시하였다. 이를 위해 GIS 프로젝트의 특성을 바탕으로 기존의 개발방법론의 GIS 프로젝트 적용시 문제점을 분석하여 GIS 개발방법론의 기본 프로세스를 제시하였다. GIS 개발방법론의 완성을 위해선 태스크 및 산출물의 정의가 추가적으로 연구되어야 하고 실질적인 검증과 표준화 과정이 남아 있으므로 본 연구는 향후의 GIS 개발방법론 정립을 위한 시작으로 간주될 수 있을 것이다.

절차적 재사용, 객체지향 사용, 디자인 패턴, 분석 패턴, 그리고 프레임 워크와 같은 효율적인 소프트웨어 재상요에 대한 많은 연구가 진행되어 오고 있다. 최근 들어 객체지향 프레임워크가 효율적이고 실용적인 재사용 기법으로 크게 부각되고 있다. 객체지향 프레임워크는 특정 도메인에 대한 여러 어플리케이션들 간의 공통된 행위들을 지닌 클래스들의 집합으로서, 재사용성을 증가시키고, 어플리케이션 개발시간을 단축시키는 효과를 지니고 있다. 그러나, 객체지향 프레임워크를 구축하기 위한 체계적인 개발 프로세스와 세부적인 개발 지침에 대한 연구가 충분히 이루어지지 않은 상태이며 OMG의 Unified Modeling Kanguage (UML)을 이용한 객체지향 프레임워크 개발에 관한 연구도 매우 미흡한 상태이다. 본 논문에서는 UML 문법과 의미를 기반으로 한 실용적인 객체지향 프레임워크 모델링 기법을 제시한다. 제시된 모델링 기법의 프로세스는 분석, 설계 구현, 그리고 시험 4단계(Phase)로 구성되어 있으며 , 각 단계는 논리적인 개발 업무(Task)들로 정의된다. 제시된 프로세스는 UML 다이어그램들을 적용 및 확장하였고, Objectory 프로세스를 바탕으로 한 것이므로 , 제시된 프로세스의 적용성 검증을 위해 전자 상거래 도메인에 대한 적용사례연구를 제시한다.

As environmental regulations have been strengthened and high fuel efficiency has been in demand in recent years, the number of ships using natural gas as a fuel is increasing. The demand for ships using LPG or methanol, which are emerging as eco-friendly vessel fuels, is also increasing. In this perspective, ME-LGI engines using LPG or methanol as a fuel have attracted considerable attention. Ships equipped with an ME-LGI engine are required to check the reliability of the fuel injection valve during shipping. This means that the development of a fuel injection valve tester is essential for the commercialization of ME-LGI engine. This study conducted the conceptual design of a fuel injection valve tester for ME-LGI engines using a system engineering process in the order of requirements analysis, functional analysis, and design synthesis. In the requirement analysis stage, the operating process of fuel injection valve was analyzed, and the necessity of checking the sealing oil leakage was then derived. In the functional analysis stage, the functions and flow of them were defined at each functional level. In the design synthesis stage, the equipment for each function was set and the process block diagram based on it was derived. In addition, preliminary risk analysis was performed as a part of system analysis and control, and safety measures were added to the conceptual design. This study is expected to be a good reference material for the concept design of other systems in the future because it shows the application process of a system engineering process to the conceptual design in detail.

With the revision of the Public Records Management Act in 2020, it has become possible to appraise long-term records more than 30 years old in the record center. However, there was no discussion on the appraisal process except for the revision of the Public Records Management Act. This study aimed to propose a process for appraisal of long-term records in the record center, focused on the roles and functions of the record center, archives, and central archives. To confirm the status and problems of the records appraisal process, we analyzed record management standards and interviewed 4 archivists who have been working as specialists for over 10 years. Based on the analysis results, the appraisal process for long-term records in the record center was redesigned in consideration of the functions and roles of the record center, archives, and central archives.

Recent social issues is energy issues, green computing has attracted attention. Active research on the power consumption of computer profiling is one of the various approaches for green computing. As a representative tool PowerAPI, PowerTop, JouleMeter, pTop, and EnergyChecker. These studies can be used to measure the power consumption of each computer device because it is based on a pure software. Based on this profiling process at the level of power consumption by performing the power consumption of each program can be analyzed. Therefore to identify the processes that consume a lot of power and control the total power consumption by reducing, also when designing the program, based on data profiling power enables the design of low-power programs, and ultimately can be oriented green computing. In this paper, by comparing and analyzing the associated representative studies, the ideal process level will draw on the characteristics of the power consumption profiler.
