Recently, using GPS and equipment that recognizes the position of the car such a computer system inside the car are very universalized. Specially, the technique that diagnoses troubles and prevents troubles through scanning engine ECU is very popularized also. However, because these data have to be directly transferred and received from the car, in cases of traffic accident such as serious damage or car theft, it is impossible to receive the data at the time of accident. In order to receive and preserve the data safely regardless of these situations, it is possible to provide data for analyzing reasons of accident and prevent accidents from occurring by using wireless communication to receive the transferred information of the car, then saving into a Database system DB, or grasping the situation of the car and the driving pattern of drivers through analyzing stored data. Moreover, due to developing some related services such as providing the information about the real time of the accident, diagnoses of the car and alarms, etc. It is expected to contribute to creating added values.

This paper presents details of the design and implementation of a report generator, Moonlight, which supports to design the report form from DB or data sources and print it to the printer. Also this paper defines the detailed model of the report system, the architecture and behavior of MoonLight, and the components of the report form, and also shows algorithms to make the report template and print the report bound to the data source. Moonlight takes advantage of XML language for the report template form. And also it is implemented by Jana language to take the advantage of platform independency. This paper also shows the results of run-time performance of Moonlight which is measured with the time to construct page objects of a report and the time to render the page objects to the print images, respectively.

In this study, we suggest the system to analyze network users' action patterns by using Data-Mining Technique. We installed Network Tap to implement the analysis system of network action and copied the network packet. The copied packet is stored at the database through MainMemoryDB(MMDB) of the high-speed. The stored data analyze the users' action patterns by using Data-Mining Technique and then report the results to the network manager on real-time. Also, we applied the standard XML document exchange method to share the data between different systems. We propose this action pattern analysis system operated embedded type of SetToBox to install easily and support low price.

This paper discusses the characteristics of sheath circulating current as well as the development and application of new software for underground power cable systems. Generally, in steady state, high sheath circulating current causes the increase of sheath temperature and thermal resistance which leads to the steeply reduction of the power capacity. Therefore, the exact calculation of sheath circulating current is required for analysis about the influence of high sheath current on permissible current. In this paper, Power Cable Simulator is developed for calculation of the sheath current. It can analyse the sheath current by real time. It is also easier to use than conventional software, such as EMTP and CabSim, because all the data for calculating the cable parameters are stored in a database(DB) within Power Cable Simulator. In addition, the accuracy of Power Cable Simulator is also proved through the comparison among the current calculated by Power Cable Simulator, EMTP and Cabsim with measured current.

A data registry is a physical place to keep characteristics of classes of objects exist in the real world when they are chosen to record as data. It provides a centralized directory to describe the meaning, representation, and identification of data elements and their values. It assists to prevent redundancy and to preserve common understanding about the data described in a metadata set. In this paper, we investigate and classify various components of IBS(Intelligent Building Systems), specially HVAC in Building Automation Systems. We present IBSDR(Intelligent Building Systems Data Registry) model that specifies not only the detailed information on data elements but also the process of documenting data in IBS. It functions as the medium to create the data sharing environment to maintain exact meaning of data for every data elements so that database management designers or related users can create and exchange their DB without major modification. It also serves as a clearinghouse for information about IBS data. So all users can freely retrieve from and register data elements to IBSDR based on ISO/IEC 11179 through World Wide Web.

Benchmarking is a process used in a lot of companies and public institutions because it is considered to be a practical tool for management innovation. However, it is hard to find out the development of systematic methods and applied cases for benchmarking on information services environment. This study tried to apply the benchmarking process to information distribution environment. This study examined the basic definition and standard process of benchmarking, and then conducted benchmarking plan to innovate tasks of database construction for information services at KISTI.

In this paper, a method to classify objects in outdoor CCTV images using Convolutional Neural Network(CNN) and background subtraction is proposed. Object candidates are extracted using background subtraction and they are classified with CNN to detect objects in the image. At the end, computation complexity is highly reduced in comparison to other object detection algorithms. A database is constructed by filming alleys and playgrounds, places where crime occurs mainly. In experiments, different image sizes and experimental settings are tested to construct a best classifier detecting person. And the final classification accuracy became 80% for same camera data and 67.5% for a different camera.

This research paper is to develop remote data transmission terminal which is adequate to RFID R/W by using UHF/RF RFID R/W module (WJR7090) and Bluetooth communication(FB755AC) with ARM chipset(AT91SAM7S256). The developed UHF RFID R/W terminal performs tagging of RPID value and transmit the value to server with Bluetooth communication, the transmitted RFID tag value is compared to the Database value and the result is transmitted to the terminal. Performance test was done in order to prove the performance of the terminal, and the test result of the terminal's excellency and transmitted/recevied packet is described.

Purpose: ASRP for the domestic development guided missiles requires not only for the reliability evaluation of the products in storage but also for the life cycle management of the products including development prototypes and initial production items. Methods: For this purpose, it should be performed to build a performance database before and after the accelerated aging test with shelf life items including development prototypes and initial production items, based on which the lifetime prediction should also be carried out. In addition, HILS must be applied for the acceptance test with the initial and follow-up production items, and also for ASRP for the long-term storage products in order to secure systematic quality assurance. Results: The results for the life cycle reliability Improving of domestic development of guided missiles are DB building of prescription Item performance, active application of HILS, Management associated with guided missiles life cycle and to Secure technology data about the introduction of foreign guided missiles. Conclusion: Furthermore, it is demanded that DTaQ, the managing agency of ASRP, actively take part in the process to maintain reliability engagement consistency over the life cycle of guided missiles.

Research and development projects in Research and development projects in Korea are ineffectively conducted due to the lack of a system for effectively planning, conducting and disseminating the result of the research projects. In this study, we have designed a framework for system that can be used in the planning and managing stage of National R & D information to guarantee standardization and extendability of the information. A national R & D technology information portal system for managing the distributed national R & D information on a single database is suggested based on this framework for the construction of a more effective information support system and the dissemination of national R & D information between researchers.
