Recently, DSRC technology is used in the various fields such as parking system, BIS, ETC, etc. This paper suggests a traffic information system using this DSRC technology. The traffic information processing based on point detection using existing vehicle detection equipment is the system in which a collection and a service are operated separately while the traffic information system based on the link detection using DSRC is able to collect and provide the traffic information through the communication between RSE and OBU. The speed of a traffic congestion is high on the process converted from a point passing speed to a link average speed because the vehicle detection equipment makes the link traffic information into the point information. When the condition of traffic is deteriorated, traffic speed of the vehicle detection equipment becomes higher than DSRC. Especially, in this system, deflection by data of the traffic speed of the traffic information system is much decreased, and the unexpected condition detection and traffic condition are provided promptly.

The growth of radidly improving computer and information technology has a profound impact upon economical, social and cultural sectors. With the progress of information technology, information-telecommunication services are produced. This service is used in sending the information to order service-users, and search the need information. This case study considers information-telecommunication service as a consumer-innovation. Information telecommunication services are provided by firms involved in collection. HiTEL(High-Telecommunication) service represents a subset of this group in that the collection, processing and transmission is primarily in an electronic from. The purpose of this paper is concerned with examining the spatial diffusion process, the issues, and behavior to used in HiTEL service one of the information-telecommunication services in Kwangju. HiTEL service is one of the typical information-telecommunication services, and is begun in Seoul and Kwangju area from October 1991, and diffusing several cities and regions now. Diffusion process of HiTEL services in Kwangju showed the irregular pattern in major residential areas, particularly Daewei-dong, Dongun-dong present higher adoption rate than other area, and where functioned as a diffusion center, the social and economic characteristics of residential area have a critical effect on diffusion process. The major adoption areas are recently built residential area, apartment districts, and diffusion direction shows two directions according to development of residental area; one is to south, another is from northeast to southwest. In order to understand the use-behavior of HiTEL service, questionary survey was carried out. Most adopters have a concern to actual life, as HiTEL, information of telephonenumber, and Daewoo Dial-Van compared with other information service. But the actual use-frequency of service is very low. In use of Kwangju regional information service, the use-frequency of operator is very low because of the lack of advertisement, the lack of providing information, and the low-concerns for regional information. But most of adopters need the providing of various regional information as regional news, education, medical and cultural events, housing, city-transportation, and job market. Thus, in order to increase and diffuse the HiTEL service, the establishment of diffusion strategies and the scheme for solution of related issues are very important. The direct diffusion strategies are the diffusion of information-mind, establishment of diffusion and education center, providing of regional information. The scheme for solution of related issues revealed in operating process are reduction of rental fee, development of the related technology and services.

Medical information is variously generated not only from medical devices but also from electronic devices. Recently, related convergence technologies from big data collection in healthcare to medical AI products for patient's condition analysis are rapidly increasing. However, there are difficulties in applying them because of independent developmental procedures. In this paper, we propose an intelligent hospital information system (iHIS) model to simplify and integrate research, development and application of medical AI technology. The proposed model includes (1) real-time patient data management, (2) specialized data management for medical AI development, and (3) real-time monitoring for patient. Using this, real-time biometric data collection and medical AI specialized data generation from patient monitoring devices, as well as specific AI applications of camera-based patient gait analysis and brain MRA-based cerebrovascular disease analysis will be introduced. Based on the proposed model, it is expected that it will be used to improve the HIS by increasing security of data management and improving practical use through consistent interface platformization.

Digital Multimedia Broadcasting (DMB) is the mobile TV service based on a digital radio transmission system that provides high quality audio/video and other auxiliary data services. As users want to store the DMB content in their device to be consumed later or to be shared among users, a standardized format needs to be specified to guarantee the interoperability for the DMB contents for various devices. DMB AF (Application Format) specification defines a file format for DMB contents and services. It specifies how to combine the variety of DMB contents with associated information for a presentation in a well-defined format that facilitates storage, interchange, management, editing, and presentation of the DMB contents in protected, governed, and interoperable ways. In this paper we present our implementation of DMB AF as part of the development of DMB AF reference software. Our implementation of DMB AF is developed as the reference software for the standard specification that consists of a three applications: packager, media player, metadata browser and collection of supporting libraries used by the applications.

The recent development of information and communication technologies brings new changes to automobile traffic systems. The most typical example is the advancement of dedicated short range communication(DSRC). DSRC mainly consists of an intelligent transportation system(ITS), an electronic toll collection system(ETCS) and an advanced traveler information system(ATIS). These wireless communications often cause unnecessary electromagnetic waves, and these electromagnetic waves, in turn, cause frequent system malfunction. To solve this problem, an absorber of electromagnetic waves is suggested. In this research, various materials, such as powdered metal and iron oxides, are used to test the possibility for an effective absorption of the unnecessary electromagnetic waves. The various metal powders are made into a thin sheet form by compositing through processing. The electromagnetic characteristics(complex permittivity, complex permeability) of the fabricated sheet are measured. As a result, we achieve -6.5 dB at 940 MHz(77.6 % absorption rate) with a 1.0 mm-thickness electromagnet wave absorber, and -9.5 dB at 940 MHz(88.8 % absorption rate) with a 2.0 mm-thickness absorber.
