In Korea, it is constructing the Intelligent Transportation System(ITS) in according with the ITS project implementation guideline and each ITS standard on the basis of "National Integrated Transportation System Efficiency Act". However, only a few ITS project implementation guideline and ITS standard for the exchange of information technologies are not able to construct a smart ITS, without technical regulation for the technical characteristics of the main ITS equipment. Therefore, in this paper, we identify the current status and problems of the legal system and look for the necessity of technical regulation enactment for the smart ITS construction.

The purpose of this study is to develop a method of integrating diverse communication networks for effectively providing ITS(Intelligent Transport System) services. In this paper, in oder to integrate communication networks, we have defined ITS services, its requirements and functions of communications. Also, we have analyzed the six important ITS services in the National ITS Architecture along with the characteristics of wireless communications. Based on the ITS service scenarios, we have derived the communication methods for ITS services.

Next-generation ITS(Intelligent Transportation System) adopts WAVE(Wireless Access in Vehicular Environment) system which is capable of the bidirectional communication system in vehicular environments. u-Transportation system adopted WAVE communications system to show the optimal performance in terms of various services with regard to vehicle safety and traffic. In this paper, we introduce testbed of ubiquitous-Transportation system and its service. Then, we describe WAVE system for supporting next-generation ITS service. Also, we carried out tests in real road environments in order to verify communication functions of WAVE systems and its performance. We confirmed that our communication systems for supporting services meet the communication performance.

While the value of information technology has long been a hot issue, few solid results have been found as of yet. It is partly due to methodological factors and model underspecifcation. This study empirically develops a ITS(information technology structure) taxonomy and investigates the relationships between ITS taxonomy and business performance in the Korean firms. Among factors that impact business performance, organization structure and control system are selected and they are hypothesized to moderate-the relationships between ITS taxonomy and business performance. By surveying 91 manufacturing firms and applying hierarchical cluster analysis, four ITS are identified : centralized, decentralized, centralized cooperative, decentralized cooperative. ANOVA, correlation analysis and crosstable analysis say the presence of moderating effect of organization structure and control system. Cooperative ITS is best in business performance. Centralized ITS is related to functional organizational form. Decentralized ITS is related to product organizational form with decentralized decision making, Centralized cooperative ITS is related to matrix organizational form. Decentralized cooperative ITS is related to matrix organizational form with high integration. These findings have implications for the opportunities and challenges to match information technology with organization structure and control system.

본 연구에서는 인터넷을 기반으로 하고 GIS(Geographical Information System)와 ITS(Intelligent Transportation System)제어 응용을 고려 한 컴퓨팅 플랫폼으로 EIMAS(Efficient and Intelligent Multi-Agent System)을 제안한다. GIS 와 관련 활용 시스템들은 개방형 지리 정보 처리 상호 운용 개념이 확산되면서 물리적으로 분산된 환경을 가지지게 되었고 이러한 분산 환경에서 프로그램개발과 사용자의 요구에 서비스를 효과적으로 제공하기 위하여, GIS와 이와 연계한 GI(Geographical Information) 활용시스템들의 각기 다른 구성 요소들을 통합하는 시스템이 요구된다. GIS 와 GIS Application으로 ITS(Intelligent Transportation System)위한 Java Mobile Agent와 Multiple Agent System 인 EIMAS를 플렛폼으로 제안한다. 이 시스템은 GIS 시스템과 ITS 시스템에 제공되는 Agent가 활동하는 플레이스 위에서 에이전트가 목적과 워크에 적합한 효율적인 워크플로우를 생성하여 시간 효율적이고 지능적인 분산. 병렬처리를 수행하는 플렛폼을 설계한다.

The most effective tutoring method is one-on-one, face-to-face in-person human tutoring. However, due to the limited availability of human tutors, computer-based alternatives have been developed. These software based alternatives are called Intelligent Tutoring Systems (ITS) which are used to tutor students in different domains. Although ITS performance is inferior to that of human teachers, the field is growing and has recently become very popular. User interfaces play key role in usability perspective of ITS. Even though ITS research has advanced, the majority of the work has concentrated on learning sciences while mostly disregarding user interfaces. Because of this, the present ITS includes effective learning modules but a less effective interface design. Usability is one approach to gauge a software's performance, while "ease of use" is one way to assess a software's quality. This paper measures the usability effectiveness of an ITS which is designed to teach Object-Oriented (OO) analysis and design concepts using Unified Modeling Language (UML). Computer Supported Usability Questionnaire (CSUQ) survey was conducted for usability evaluation of UML-ITS. According to participants' responses to the system's usability survey, all responses lie between 1 to 3 scale points which indicate that the participants were satisfied and comfortable with most of the system's interface features.
