Data Envelopment Analysis (DEA) is a theoretically sound framework for performance analysis that offers many advantages over traditional methods such as performance ratios and regression analysis. Largely the result of multidisciplinary research during the last three decades in economics, engineering and management, DEA is best described as an effective new way of visualizing and analyzing performance data. Besides, overseas information technology companies have aggressively tried to enter the domestic market. In the age of globalization and high competition, it is imperative that the system integration (SI) companies need to introduce the performance evaluation models of SI projects, including Capability Maturity Model and Software Process Improvement and Capability Determination, to gain a competitive advantage. Therefore, it makes our research regarding evaluation of SI projects very opportune. The purpose of the study is not only to evaluate efficiency of each project by DEA but also to gain insight into various factors such as project complexity, team members' man-months structure, and process index(project management index) that link to the projects performance.

The dynamic information of radar and automatic identification system (AIS) for targets obtained from the traffic vessels operating in the north outer harbor and surrounding waters of Busan port, Korea. The target information was analyzed to investigate the potential collision risk resulting from the invalid true heading (HDT) information of AIS and the integration ambiguity in the graphic presentation of both tracked data sets for two systems. An integrated display system (IDS) for supporting the navigator of offshore fishing vessels was also developed to find possible maneuvering solutions for collision avoidance by comparing radar data with AIS data in real-time at sea. Consequently, the multiple functions of IDS can provide additional information that is potentially valuable for taking action to avoid the collision in offshore fishing vessels. However, the integration criteria of radar and AIS targets in the IDS must be carefully established to eliminate the fusion ambiguity in the graphic presentation of both AIS and radar symbols such as the one or two physical targets which are very close to each other.

본 연구에서는 수도권을 중심으로 구축 운영 중에 있는 ITS 무선통신 인프라인 UTIS 서비스 지역을 확대하는 방안으로 전국에 약 5,000여대가 설치되어 있는 무인단속장비와 UTIS 기지국을 통합하는 방안을 제시하였다. 기존의 UTIS는 25m 높이에 기지국이 설치되고 광통신망을 통해 센터와 통신하는 반면, 무인단속장비는 6.6m 높이에 설치되어 임대 통신망을 통해 센터와 통신하는 등의 차이가 있다. 무인단속장비와 UTIS 기지국의 효율적인 통합방안을 제시하기 위해서 현황분석을 통해 1,628개소의 통합설치 개소를 선정하였고, 현장시험을 통해서 6.6m의 높이에서도 UTIS 요구성능을 만족하는 것을 확인하였다. 또한 통합에 적합한 통신망 및 시스템 구성방안을 제시하였으며, 통합 설치 시 비용 절감효과를 분석하여 현장시스템 구축 비용이 UTIS 기지국 단독 설치 시에 비해 약 1/5 수준으로 절감됨을 확인하였다.

By an explosive increase of proxy driving, customers require the quick and correct services of call center. But because most call centers have an unsystematic management system, grievance of customers is continually increasing. To solve these problem, we constructed a call center system of proxy driving that is based on CTI (Computer Telephony Integration) in this paper. The proposed system is constructed using CID (Caller Identify Display) terminal, SMS (Short Message Service) and call center management program etc. Customer service level could be improved through efficient customer management by using the proposed system. Also it could be convenient and easy to implement customer management, order management, staff management, SMS and settlement of accounts.

The integration of deburring robots into product quality and productivity impact the industrial. In this paper the intelligent system of robotic deburring is proposed integrated with robot system, image processing system, force sensor system and host PC. The size, position, recognition of burr is determined by the information that the image processing system processed. The feed velocity of cutting tool is controlled by the information that the force sensor system processed. The integration of these information can remove the uncertainty of the information of deburring on the cutting path. The result of these technologies is useful for the development of the factory automation and automatic inspection equipments.

In this paper, we suggest an XML Development Support(XDS) System as a good developing tool to solve the problems that related with the database integration, increased to the developing terms and costs when the developing of XML programming base on the web server. XDS System is designed for the purpose of easily coding the XML program, of simply changing the programming structure and of completely maintaining the program environment. According to the predefined policy, XDS System provides necessary informations such as tables, columns, or relational keys from Database for developer. The developer step by step selects or sets what he needs. And XDS System creates an XML Tree with the result of selected information. The XML Tree includes all information of making an XML Schema and some XML Stylesheet. XDS System creates an XML Schema for all clients and creates many XML Stylesheets for each client using the XML Tree.

최근 건설 정보 통합 모델에 설계 요소를 반영하는 개념이 발표되고, 4D CAD 시스템을 이용한 정보 통합에 대한 연구들이 수행되었으며, 현재까지 그 활용분야를 넓히고 있다. 하지만, 이러한 형태의 정보통합은 특정 응용 프로그램을 중심으로 이루어지기 때문에 각 조직만의 독특한 내용적 특성을 반영할 수 없으며, 기존의 프로그램과 다른 새로운 프로그램의 도입 및 개발에 따른 유지, 보수 비용을 요구하는 등의 단점이 있다. 본 연구에서는 이러한 문제들을 해결하기 위하여 정보통합을 위한 새로운 접근 방법으로써 '프로덕트 모델 중심의 설계, 시공 정보 통합 방법론'을 제시하고 이에 대한 비교 평가를 위하여 기존의 방법론에 대한 선행 연구를 수행하였다. 이를 위하여 현재 설계, 공정 정보의 통합을 위하여 널리 사용되고 있는 4D CAD 개념을 조사, 분석하였다. 연구 분석 결과 기존의 통합 방법론은 여러가지 장점이 있었지만, 전체 건설사업의 생애주기 중 후반부에 통합이 이루어지기 때문에 정보 활용의 기회가 적으며, 후속단계에서 원시정보의 활용이 미흡하고, 통합 정보의 활용 범위가 상용프로그램이 제공하는 기능으로 제한되고, 3차원 프로덕트 모델에 대한 관리가 곤란하였다. 이러한 단점을 해결하기 위한 설계, 시공 정보의 통합을 위한 새로운 방법론을 제시하였다. 제안된 방법론은 '일관된 객체 기반의 그래픽 모델링', '이질적인 프로덕트 정보들의 저장', '프로덕트 모델을 활용한 정보의 생성, 통합', '확장된 프로덕트 모델의 관리' 등의 4 부분으로 나누어서 제안하였으며, 마지막으로 이들에 대한 활용 개념을 기존의 업무에서의 활용과 새롭게 보충되는 업무에서의 활용으로 나누어서 제안하였다. 6장에서는 본 논문의 전체적인 요약과 후속 연구 주제들과 이를 위한 제안을 하였다. 본 연구를 통해서 특정 응용프로그램 중심의 통합이 아닌 프로덕트 모델 중심의 설계, 시공정보 통합을 위한 새로운 통합 방법론을 제시하였으며, 본 방법론을 통해서 실제로 사용하고 있는 프로그램들을 활용하면서, 각 조직의 환경에 적합한 정보 통합을 통해 건설 생산성 향상을 기대할 수 있게 되었다.

In this paper, we implement a common module that can integrate multiple biometric information for integrated patient monitoring system. Conventional biomedical instruments have many devices attached to each patient, making it difficult to monitor abnormality signs of many patients in real time. In this paper, we propose a module for an integrated monitoring system that can perform centralized monitoring using a common module that integrates multiple measurement devices. A protocol for sending and receiving packets between the measuring device and the common module is designed, and the packets transmitted through the network are stored and managed through the integrated monitoring system and provide information to various users such as medical staff. The results of this study are expected to contribute to the management of patients and efficient medical services in hospitals.
