Recently, business environments have been changing quickly. To establish competitive advantage, most enterprises have been using information systems such as Enterprise Resource Planning (ERP), Supply Chain Management (SCM) and Customer Relationship Management (CRM). Many consider Business Process Management (BPM) a new innovative solution for enterprise-wide processes. As the BPM system is used more widely and matures, new techniques and functions will be developed by commercial vendors. However, they mainly focus on correctly executing process models, and user convenience has not been considered. In this paper, we have developed a new method of designing business processes, which provides users with an easy modeling interface. The method is based on version management. Version management of a process enables a history of the process model to be recorded. In order to prevent wasted storage, not all of the process versions are stored. An initial version and changes to each process are stored by automatically detecting changes. Our method enhances the convenience of the modeling business processes and thus helps the process designer. A prototype system is presented to verify the effectiveness of our method.

컴포넌트 기반 소프트웨어 개발(CBSD: Component Based Software Development)이 재사용을 통한 소프트웨어 개발의 효율적인 방법으로 인식되고 있다. CBSD의 목적은 새로운 시스템을 개발하고자 할 때 검증된 컴포넌트, 검증된 업무 로직을 재사용 함으로써 개발 기간을 단축하고 품질을 향상하고자 하는 것에 있다. 본 논문에서는 기 존재하는 객체지향 어플리케이션을 폐기하지 않고, 이를 기반으로 재사용 성이 높은 컴포넌트로 추출하기 위하여, 컴포넌트 추출을 위한 메트릭과 인터페이스 추출 방안을 제시하였다. 클래스간의 관계 정보를 이용하여 복잡도, 응집도와 결합도를 측정하고, 이의 결과를 이용하여 후보 컴포넌트를 추출한다.

This paper presents an efficient methodology for information system development by adopting the concept of extended components which can achieve the improvement of development productivity, reductrion of development time periods, quality improvement of information systems, etc. when information development projects are carried out. First of all, for efficient development of information systems, development steps of current methodologies for information system analysis are subdivided into components in detail and outputs required at each step are defined. The components are extended by types and various application methods are proposed in each step of information system development. In addition, a method which uses advantages of current methods such as SDLC, prototyping, and RAD, is also proposed. In this research, a CASE tool named S-Designer is used for the development of extended components and their interface, and a system development method called DSDM for the deviation of detailed steps and corresponding outputs.

Intelligent applications are crucial for increasing the popularity of shared urban electric bicycles (EBs). Building an application platform architectural system that can satisfy independent user operations is critical for increasing the intelligent usage of shared EBs. Consequently, we collected online reviews of shared EB applications, conducted semantic processing and sentiment analysis, and refined the positive and negative review data for each function. The positive and negative review indices of each function were calculated using the formulae for positive and negative review indices of product functions, thereby determining the functions that need to be improved. Each function of the Shared EB application was improved according to its business process. The main contributions of this study are to build a user requirement architecture system for the Shared EB application with five dimensions and 22 functions using the Delphi method to design the user interface (UI) of this application based on user satisfaction evaluation results; to create a high-fidelity dynamic interaction prototype and compare user satisfaction before and after improving the Shared EB application functions. The testing results indicate that the changes in the UI significantly improve the user experience satisfaction of the urban Shared EB application, with the positive experience index increasing by 69.21% and the negative experience index decreasing by 75.85% overall. This information can be directly used by relevant companies to improve the functions of the Shared EB application.

Today’s information technology departments face a dilemma to create a competitive advantage for the organization by developing. deploying, and managing distributed applications that scale across the LAN, WAN, and Internet, while preserving investments in systems. Applications, information. IT organizations are today being asked to build the future, without breaking systems that maintain the current business. A possible answer to this dilemma is the implementation of a multi-tier distributed computing architecture. Multi-tier architecture has the potential to provide better, more timely information across the enterprise at a lower cost than the current combination of PC LAN, two-tier client/server, or mainframe applications that have been developed in most organizations. In this paper, we implement management information system based on distributed object middleware using multi-tier distributed computing architecture. This system uses Microsoft's implementation of DCOM/ActiveX and provides easily accessible web interface to the system users.

B2C(Business to Customer) 산업에 있어 효율적인 성과관리를 위해서는 고객이 원하는 서비스 요소를 추론하여 고객이 원하는 서비스를 제공하고 그 결과를 평가하여 지속적으로 서비스품질 및 성과를 향상 할 수 있도록 해야 한다. 그것을 위한 중요한 요소는 고객 만족도의 정확한 피드백인데 현재 국내에는 고객의 만족도 측정에 대한 정량적이고 표준화된 시스템이 열악한 상황이다. 최근 얼굴표정 및 생체데이터를 감지하여 사람의 감정을 인식하는 휴대폰 및 관련서비스 기술에 관한 연구가 증가하고 있다. 얼굴에서의 감정인식은 현재 연구되어지는 여러 가지 감정인식 중에서 효율적이고 자연스러운 휴먼 인터페이스로 기대되고 있다. 본 연구에서는 효율적인 얼굴감정 인식에 대한 분석을 하고 고객의 얼굴감정인식을 이용하여 고객의 만족도를 추론할 수 있는 고객피드백시스템을 제안한다.

It was difficult that each enterprise clearly defines PDM in domestic vehicle manufacturing industry and decides investment for the successful foundation in the mid-90s. Also, it was true that most investments to success repeat a process of trial and error even if they decide and propel. Now, PDM is not a luxurious system. Because the company is operated well even if it manages business manually, the company may not be interested in PDM introduction. Problem is business efficiency and product competitiveness. Now, we must consider that introduction and drive of PDM became necessary as instrumentation for Re-Engineering of business process concerning innovative dimension restructuring that is not reorganization, development and improvement of business for enterprise's survival. This indicates that now is when level of infra construction for an IT technology dominates competitiveness of business management. Enterprise can expect effects of PDM by implementation that manages Intellectual Properties through administration of knowledge and information finally.

중소기업의 정보화 영역은 생산정보화, 경영관리자동화, 네트워크화의 3가지 요소로 구분된다. 본 논문은 경영정보시스템을 이용하는 경영관리자동화를 주로 다룬다. 기능적으로 보면 생산, 판매, 인사, 회계 등 4개의 분야로 크게 나누어지나 대부분의 중소기업은 생산과 판매에 더 많은 주안점을 둔다. 따라서 이 두 개의 핵심 기능을 중심으로 객체지향방법론에 기반하여 통합된 정보시스템이 구축된다. 본 논문이 제안하는 단계별모델의 중요한 하나의 단계인 이 통합시스템은 단순화와 집중화의 원리를 수용했을 뿐만 아니라 객체지향패러다임을 이용하여 모듈화 및 친숙화를 구현하였다.
