In order to reproduce the traffic accident, It must save the data automatically which traffic accident 30 seconds before using black box. The Black Box can detect traffic crash accidents automatically, and record the vehicle's motion and driver's maneuvers during a pre-defined time Belied before and after the accident. But it is not easy for the police to catch running away criminal. Because, criminal can remove proof if it is 2 hours or 3 hours at least. Therefore, in this paper, in order to catch a hit and run driver in the traffic accident road, it developed an structured Query Language Server and made parts database algorithm.

Recently, as a vehicle black box device has propagated, it has been increasingly used as a legal proof and there are the needs to verify an integrity of the video data. However, since the black box classified as the embedded system has a small capacity and low processing speed, there are limitations to the storage of video files and the integrity verification processing. In this paper, we propose a novel method for video files integrity in the black box environment with limited resources by using lightweight hash function LSH and the security of HMAC. We also present the test results of CPU idle rate at integrity verification in vehicle black box device by implementing this method, and verify the effectiveness and practicality of the proposed method.

Recently, devices such as smartphone and vehicle blackbox and EDR(Evern Data Recorder knowed automotive real-time control and driving data to use OBD-2(in-vehicle network). when devices receive vehicle driving data, communication way use each Wifi, Bluetooth. but if user and driver change device to use OBD-2 connect, the device differ communication network way. and driver buy and change OBD-2 connect. In this paper, to remedy one's shortcomings, there integrate Bluetooth and Wifi network module and design integrability hardware as any another device know vehicle real-time control and driving data with one integrability connect.

This paper presents the development of a core module for integrating data from vehicle by the convergence technology of mobile telematics and black-box. This emerging technology can be referred to as Black-box in Mobile (BIM). For the development of BIM, sensors and cameras were realized in a driving robot. Relevant hardware implementation was achieved to verify the functionality of BIM. The transmitted signal from the driving robot was confirmed in an Android-based portable device. Existing Black-boxes were mostly developed by major transportation companies and focused only on storing data. The proposed BIM offers not only data storage but also easy-to-use real-time monitoring while in motion. In addition, the vehicle can be monitored on parking through shock sensors. This development is considered commercially viable as it is achieved via software implementation.

Driver for safety always check the status of their vehicle, and it is essential to understand. When driver know vehicle driving status, there is know vehicle driving status to use vehicle realtime control data by OBD-II of vehicle network and connected OBD-II connector. But, connector to receive OBD-II data differ each communication connection method to connect smart device.(such as smartphone, blackbox, EDR) if vehicle driver change another smart device from smart device(such as android -> iphone, iphone -> android), vehicle driver exist the inconvenience that purchase new OBD-II connector. in this paper, As make up for the fault, there is to implement one OBD-II connector that integrate Bluetooth, Wifi, WCDMA module. as result, anything smart device was notified realtime vehicle control data through implemented one OBD-II connector in this paper

Many of crimes are solved by the report of people. Therefore, countries pay compensation to crime reporter. However, the current system of compensation is focused on the report of criminal fact and criminals arrest, so that there is no compensation on the providing evidence. On the other hand, since the current judicial system adopted the principle of trial by evidence, all the facts are made by the evidence. But it is impossible to obtain all the evidence only by law enforcement agencies. Therefore, it is necessary for people to report the evidence positively. So it is necessary to positively take advantages of smart phones, vehicle black boxes and cctvs. Various incentives such as compensation would be needed to require the evidence of smartphone or black box, cctv. In order to strengthen evidence report, it will be needed the legislation of crime report compensation, smartphone apps development including the provision of various incentives.

How would technoscientists collaborate in their technoscientific practices? Based on the ethnographic research done at NRI(Neuroscience Research Institute), this research shows how collaboration occurs in/outside the interdisciplinary laboratory. As previous studies show, collaboration makes researches possible that otherwise would have been impossible. Korean technoscientists who are situated in the scientific periphery, practice contextualized collaboration in their labs. These collaborations are invisible before opening the black box of the lab. But it acquires visibility after certain incidents such as collaborations, debates and discussions, malfunctioning of the instruments, and networking with other actors occur. These networks again become invisible after the certain incidents end. However these blackboxing and whiteboxing (opening the blackbox) processes occur simultaneously in various levels, it is almost impossible to identify them separately. In real technoscientific practices, blackboxing and whiteboxing do not occur distinctively. They almost always occur at the same time on multi-layered levels, hence forming the 'grey box' of technoscientific practices. Lastly, collaborations inside laboratory have in/visible features, because laboratories function as Foucauldian heterotopias.

Vehicle black boxes that have similar functions as airplane black boxes are currently being used due to the loss of many lives and properties arising from vehicle accidents. Both black-box products and Event Data Recorder(EDR) systems are currently available in the market. Most of the existing in-vehicle black boxes, however, record only external videos and images and cannot show the vehicle's driving status, whereas EDR products record only the driving status and not external videos. To address the problem of black boxes that can record only videos and images and that of EDR systems that can record only driving data, an integrated vehicle state and video recording system that uses MOST(Media-oriented System Transport) and OBD-II(Onboard Diagnostics II) and CAM (camera) and GPS (global positioning system).

THe purpose of this study is to forecast of runoff hydrographs according to rainfall event in a stream. The neural network theory as a hydrologic blackbox model is used to solve hydrological problems. The Back-Propagation(BP) algorithm by the Levenberg-Marquardt(LM) techniques and Radial Basis Function(RBF) network in Neural Network(NN) models are used. Runoff hydrograph is forecasted in Bocheongstream basin which is a IHP the representative basin. The possibility of a simulation for runoff hydrographs about unlearned stations is considered. The results show that NN models are performed to effective learning for rainfall-runoff process of hydrologic system which involves a complexity and nonliner relationships. The RBF networks consist of 2 learning steps. The first step is an unsupervised learning in hidden layer and the next step is a supervised learning in output layer. Therefore, the RBF networks could provide rather time saved in the learning step than the BP algorithm. The peak discharge both BP algorithm and RBF network model in the estimation of an unlearned are a is trended to observed values.

The paper aims to identify major research issues and basic framework of computer supported collaborative work in design through reviewing recent changes in product development which is getting more integrated, collaborative and computerized. At first the importance of collaborative work in design is discussed throughout the development of design process: from blackbox approach in vernacular design to recent Nigel Cross' es Hybrid model. Then Concurrent Engineering and Quality Function Depolyment are reviewed for showing recent phenomena of integration and collaboration in the process of product development. Computer-aided product development is demonstrated with the case of Blackboard system and Computergenerated form development. In order to outline the fundamental approach for computer-supported collaborative work in design, structures and processes of some related projects are introduced. Finally, based on the findings, some research issues for further rJevelopment are proposed.
