  • Dedicated Short Range Communications(DSRC) is a block of spectrum in the 5.8GHz band. DSRC is the useful technology of ITS Service. Japan operates ETCS, VICS by DSRC technology and DSRC technology is used ETCS Standard in Korea. There are many kind of utilization of DSRC in ITS. This is a study for traffic information service and collection with DSRC. Traffic management server service traffic information to driving vehicle by RSE(Road Side Equipment). OBU(Onboard Unit) in vehicle send the information to PDA(Personal Digital Assistant). Client S/W show the information to driver by text, pictogram, sound and return PDA H/W ID to OBU. Server make section traffic information by the PDA H/W ID information.

  • Existing exploration robot is able to control its speed using technologies such as the remote control and deep learning. However its speed control method using weather information has not been proposed. To overcome the problem of conventional methods without using the weather information which is an useful ordinary life information, this paper proposes a new speed control method of exploration robot using weather information gathered from RSS service which is offered without cost by the Meteorological Agency. The exploration robot implemented in this paper is controled by the remote control through the TCP/IP communication and provides real-time real spot figure gathered from its camera sensor within the range of WiFi. Additionally, according to the weather information from URL of the Meteorological Agency, the implemented exploration robot autonomously controls it speed. The correct performance of the proposed method is verified by the experimental measurement data of its speed according to the precipitation probability and wind speed in this paper.

  • General methods of controlling a drone are divided into manual control and automatic control, which means a drone moves along the route. In case of manual control, a man should be able to figure out the location and status of a drone and have a controller to control it remotely. When people control a drone, they collect information about the location and position of a drone with the eyes and have its internal information such as the battery voltage and atmospheric pressure delivered through telemetry. They make a decision about the movement of a drone based on the gathered information and control it with a radio device. The automatic control method of a drone finding its route itself is not much different from manual control by man. The information about the position of a drone is collected with the gyro and accelerator sensor, and the internal information is delivered to the CPU digitally. The location information of a drone is collected with GPS, atmospheric pressure sensors, camera sensors, and ultrasound sensors. This paper presents an investigation into drone control by a remote computer. Instead of using the automatic control function of a drone, this approach involves a computer observing a drone, determining its movement based on the observation results, and controlling it with a radio device. The computer with a Depth camera collects information, makes a decision, and controls a drone in a similar way to human beings, which makes it applicable to various fields. Its usability is enhanced further since it can control common commercial drones instead of specially manufactured drones for swarm flight. It can also be used to prevent drones clashing each other, control access to a drone, and control drones with no permit.

  • This paper presents the evaluation result of the Namsan 1st tunnel traffic information system, which is providing the real time queue length status and incidence information inside of the Namsan 1st tunnel, 1600meters long in the Seoul metropolitan CBD. This information system plays an important role because of notifying drivers to pay a toll for the tunnel path, the congestion information in advance. According to the analysis, an evident improvement on the tunnel path and its bypass without any conspicious adverse impact. Furthermore, survey analysis found that motorists placed a high value on the provided information. During peak time, the system turned out to help motorists to relax their hasty minds. As well, several performance indices showed the reduction of congestion and travel time variation on both of the tunnel path and its bypass, in spite of no traffic information on the bypass.

  • Our government has concentrated its policy capabilities on Software industry in order to realize software-centric society. Through such efforts, software industry has developed continuously. As well, it has been a high-valued industry by the association with other various industries, so its importance has been great and its market has grown explosively. However, owing to the hasty support policies focused on software industry, various problems and adverse effects, such as the decline of construction quality due to the confusion of business operator selection and the business area conflict, has occurred. Therefore, in this thesis, I will find the problem and its cause about software support policies and relevant laws according to rapid market change, and will suggest the improvement plan about them. So, I intend to minimize the problems associated with the confusion of business operator selection, through the business area clarification(software industry and information communication construction industry) about complex ICT industry.

  • Strategic information systems assist organization with the significant opportunity to gain competitive advantage in executing its business plans and realizing its business goals. The universities establish long-range plan of information systems in an effort to provide just-in-time, useful, efficient and effective information services to their members such as professors, students, and staffs when carrying out various organizational activities. The university information systems started from the primitive computer-based application, extended to the administrative and educational e-transformation, even to the virtual university concept. Through an empirical analysis and complementary case examples, the current study carefully chose three Korean universities according to their chronological importance, that have undergone the information systems planning process years from 1995 to 2001. These universities then, were compared in terms of the information technology architecture: the information architecture, infra architecture, and information management architecture. These three areas of system were cross-examined under the consideration of the evolution of information technology architecture, and its impact on the development of university e-transformation. As part of a fulfillment plan to satisfy the needs of customers of current trend, it is evident that the university e-transformation provides a stepladder to highly competitive, first class university in the market, through achieving the educational advancement, research enhancement, and administrative efficiency. The result of the study analysis indicates that, of the three architectures examined, the weakness showed in the information management architecture. Therefore it is crucial for the university staffs, managers and professors to understand the significance of the successful implementation of the information system and its maintenance. Our study certainly will act as a catalyst for the promotion of the future university e-transformation projects.
