A workflow model is useful fur business process analysis and has often been implemented for office automation through information technology. Accordingly, the results of workflow modeling need to be systematically managed as information assets. In order to manage the modeling process effectively, it is necessary to enhance the efficiency of their reuse. Therefore, this paper creates a Document-barred Workflow Modeling Support System (DWMSS) using a case-based reasoning (CBR) approach. It proposes a system architecture, and the corresponding modeling process is developed. Furthermore, a repository, which consists of a case base and vocabulary base, is built. A carte study is illustrated to demonstrate the usefulness of th is system.

최근 전산환경은 웹 환경에 적합한 개방형 시스템으로 변모하고 있다. 서로 다른 플랫폼을 기반으로 한 클라이언트들과의 연동을 위해서, 각 시스템에 따른 어플리케이션이 개발되어야 했다. 이러한 문제점을 극복하기 위해 JDBC를 이용한 이 기종간의 시스템을 통합할 수 있는 통합 시스템 필요하다. 따라서, 본 논문에서는 인터넷 환경하에서 생성되는 산출물을 객체 형태로 통합 관리하고, 데이터베이스와 연결하여 객체들을 효율적으로 관리해 주는 웹기반 통합 객체 관리 모델을 설계한다. 이 모델로 기존의 시스템을 재사용하고 급변하는 소프트웨어 산업에 능동적으로 대체와 소프트웨어 개발에 시간을 단축함으로써 현존하는 다양한 데이터베이스군들을 최소한의 코드 수정을 통하여 구동할 수 있게 함으로써 경제성을 높이는 것이 본 논문의 목적이다.

정보 시스템을 개발하고 관리하는 제반 활동들이 효율적으로 수행되고 있는지 점검하고 확인할 필요가 있다. 지금까지의 감리는 감리인의 정보 시스템 개발 및 감리경험에 의존하고 있으며, 평가방법에 있는 각 항목 기준이 애매하고, 정성적 평가로 인해 객관성이 결여되었다. 또한, 감리 정보 시스템이 개발되지 않아서 감리업무 평가에 활용되지 못하는 한계점이 있었다. 본 논문에서는 기존 감리업무의 제반 문제점을 해결하기 위하여 감리 정보 시스템의 모델을 제안하고, 시험 감리를 위한 감리 정보 시스템을 설계한다.

본 논문은 자바 환경의 이동에이전트 시스템인 JAMAS를 기반으로 한 이동에이전트를 응용하여 망 관리를 구현한다. 오늘날의 통신망은 전형적으로 이형의 다중 플랫폼이며, 서로 다른 제조회사의 통신망 장비를 복합적으로 구성하여 사용하기 때문에 이식성과 플랫폼 독립성을 지원하는 이동에이전트를 이용하는 것이 효율적이다. 따라서, 이동에이전트는 관리 장비에 SNMP 에이전트처럼 정적으로 존재하는 것이 아니라, 관리자를 대신하여 이동하고 자율적인 실행을 통해 통신망 장애를 진단하고 고칠 수 있도록 독립적으로 기능 구현이 가능하며, 나아가 지능이 있는 이동에이전트를 제공할 수 있다. 본 논문은 통신망 관리를 위해서 SNMP의 관리 정보인 MIB를 이동에이전트가 접근하여 수집한 후, 관리자에게 전달하는 MIB 브라우저 역할 수행의 이동에이전트를 구현하고, 성능 평가를 하여 효율성을 입증한다

The welding distortion of a hull structure in the shipbuilding industry is inevitable at each assembly stage. This geometric inaccuracy caused by the welding distortion tends to preclude the introduction of automation and mechanization and needs the additional man-hours for the adjusting work at the following assembly stage. To overcome this problem, a distortion control method should be applied. For this purpose, it is necessary to develop an accurate prediction method which can explicitly account for the influence of various factors on the welding distortion. The validity of the prediction method must be also clarified through experiments. For the purpose of reducing the weld-induced bending deflection, this paper proposes the mechanical tensioning method (MTM) as the optimum distortion control method. The validity of this method has been substantiated by a number of numerical simulations and actual measurements.

With the advent of the fourth industry, the need for office automation with automatic character recognition capabilities is increasing day by day. Therefore, in this paper, we study a character recognition algorithm that effectively recognizes a new experimental data character by using learning data characters. The proposed algorithm computes the degree of similarity that the structural regions of learning data characters match the corresponding regions of the experimental data character. It has been confirmed that satisfactory results can be obtained by selecting the learning data character with the highest degree of similarity in the matching process as the final recognition result for a given experimental data character.

Many countries around the world using ICT technologies have various technologies to keep pace with the 4th industrial revolution, and various algorithms and systems have been developed accordingly. Among them, many industries and researchers are investing in unmanned automation systems based on AI. At the time when new technology development and algorithms are developed, decision-making by big data analysis applied to AI systems must be equipped with more sophistication. We apply, Pearson's correlation analysis is applied to six independent variables to find out the job satisfaction that office workers feel according to their job characteristics. First, a correlation coefficient is obtained to find out the degree of correlation for each variable. Second, the presence or absence of correlation for each data is verified through hypothesis testing. Third, after visualization processing using the size of the correlation coefficient, the degree of correlation between data is investigated. Fourth, the degree of correlation between variables will be verified based on the correlation coefficient obtained through the experiment and the results of the hypothesis test

This paper discusses the application of collaborative robots to the de-palletizing in IMC (Inte-grated Mail Center). The domestic courier logistics market has grown rapidly, and logistics centers are reaching critical capacity. Therefore, digital innovation based on logistics automation is necessary, and this paper looks at the factors to be considered when introducing collaborative robots and improvement measures considering the characteristics of the de-palletizing task. The benefits of introducing collaborative robots include immediate efficiency and the goal of assisting workers. The paper reviews related research and cases of collaborative robots applied to logistics centers and summarizes the results of collaborative robots introduced to actual postal logistics centers. The paper also provides a comparison of collaborative robots and industrial robots and presents four candidates for collaborative robots for logistics work. The paper also considers suction grippers to be mounted on the arm to grasp the parcel. The paper concludes by discussing the introduction of collaborative robots in the post office logistics center.

Needs of automation and computerization in the construction industry has been recognized but the implementation of e-business solutions with project management systems has not been fully explored. In order to cope with different management practices in home office and project sites, integration of two popular systems, Enterprise Resource Planning (ERP) and Project Management System (PMS) is essential. The objective of this study is to find ways to functionally and systematically integrate ERP and PMS. With the integration of ERP and PMS, a project will be managed much more efficiently and effectively. It is expected that this study will benefit system integrators and help them to understand construction management processes and integrate the solutions with minimized programming work.
