In this paper, we implemented the sign board system that displays user's image, user's sentence, the information from DARC an[1 information based position by GPS module for vehicle. The existing sign board is displaying only user's image and sentence. Or other existing sign board is displaying the information via CDMA network. However, our system is also able to display the user's message like other system and gain the information more cheap by DARC. This system consists of 6 parts. The DARC control part classes the DARC information - news, weather, stock and time. The GPS control part gains moment and item to display with calculating the information of global position, direction, speed and satellite. The LED control part has two buffers to store and handle the image. The buffers help the system display various effected images on LED board. An external memory card includes the location based data, the option file and the displayed data files. The data files are stored by FAT 16 with the folder structure on external memory card. The USB controls the communication with PC. PC programs can control and monitor this system. This system is using G72l voice file format, for casting the information. This system was established at the vehicle and we monitored this system. The system displayed the DARC data , user's data and the location based data on the LED board, successfully.

This research is aimed at proposing the policies for enhancing information services at the GARS. To this end, a survey was carried out over the user group, the staff group, and the external expert group. And then the 3-Partner Approach Model was proposed that accommodates the archivist-centered partnership with users and external experts. Based on this model. the three-aspect policies to upgrade information services were proposed.

Purpose: The purpose of this study was to establish novice user guidelines for efficient external laryngeal manipulation for intubation in difficult airway management. Methods: This study included 59 pre-qualified junior and senior emergency medical service students. The participants were instructed at random to intubate a manikin equipped with a cervical collar, thus simulating a difficult airway, using three types of external laryngeal manipulation: bimanual laryngoscopy, backward-rightward pressure, and cricoid pressure. The resultant intubation time and glottic view grade scores were estimated. Results: Intubation time was longest using the bimanual manipulation method, followed by cricoid pressure and backward-rightward pressure. A low Cormack-Lehane glottic view score was obtained regardless of the assisted compression method used. Conclusion: Backward-rightward pressure may be the most efficient method of external laryngeal manipulation on the basis of the intubation time and improvement in glottic view.

The existing mashup service providers have induced users to participate in their own made services and have grown their services by user participations and contributing contents. Recent services based on Web2.0 are called by 'Open (Content) Service' which means anyone can provide new services to the others without any of their own contents. But unfortunately the most of these days services are not opened. They just using mashups for increasing their service's traffics. We introduce the way to make a simple service to provide searching videos present it with extracted keyword from external content without our own contents at all. this show that how to combine the content with another contents or services.

The object of this work is to develop an assessment system for pipeline integrity. the system consists of four module applications for internal algorithm; the effect of corrosion in pipeline, crack, stress corrosion crack (SCC) and fatigue modules. Presently, the module of the external corrosion has been developed and the internal algorithm for the effect of corrosion in pipeline and the database of the system are described in this paper. The database of the system is separated to mainly four parts; geometry of pipeline, material properties, boundary conditions and general properties. Each components of the system are designed by user-friendly concept. This system may give a guideline for maintenance and modifications for the pipeline at the industrial sight. Furthermore, a procedure to evaluate an inspection interval is also provided.

In accordance with the growing importance of software in computer systems, software quality and performance has become a hot issue in all computer-related fields and businesses. But the measurement and evaluation of software quality still poses a problem, due to the different viewpoints of software developers and users. This study attempts to combine the external characteristics of quality representing the viewpoint of users, and the internal characteristics representing the viewpoint of developers of quality. In order to do this, this study provides multiple models which select the appropriate internal characteristics which reflect user requirements from earlier phases of development. The goal of this study is to enhance the applicability of 40 internal characteristics of ISO 9126 to the models.

This paper proposes mechanism to build a economical access control system when a user's host requires block to an external network, such as computer class conducted at educational institutions. The proposed mechanism is to block clients from accessing the external network by using the one of MITM(Man In The Middle) technique, ARP Spoofing. It prevents packets from being forwarded to outside by gateway. So It can build system simply and economically because Client hosts are don't need to install firewall or any extra agent.

A mechanism for collision detection in general animation system is necessary to prevent the interpenetration among multiple objects. On the other hand, a dynamic simulation system which is a part of animation system simulates realistic motions using dynamics after the collision, which is called collision response. In this paper, a method for reducing the CPU time for collision detection by removing redundant calculations and object sorting is proposed. A dynamic simulation system including collision detection and response function was implemented to demonstrate the proposed methods, where the input data as elasticity, friction, gravity, object shape, external force and external torque are given by the user. The system simulates motions of multiple objects using dynamics, and generates the wireframe display.

Visualizations have played an important role in understanding new insights of users of social network for social network analysis. Most of the previous works of visualization focus on representing user's relationship on social network by a complex multi dimension graph. However, this method is difficult to identify the important of relationship to focus on personal user intuitively. Besides, the user's messages to reflect the interrelation between users is insufficient, since most of visualization methods represent the user relationship using information of interaction between nodes on networks. In order to resolve above problem, this paper proposes a new visualization method to visualize user based hierarchy that uses internal relationship of users by fuzzy relational product and external access information of network.

With the rapid development of big data and Internet technologies among IT technologies, it is being changed into an environment where data stored in the cloud environment can be used wherever the Internet is connected, without storing important data in an external storage device such as USB. However, protection of users' privacy information is becoming increasingly important as the data being processed in the cloud environment is changed into an environment that can be easily handled. In this paper, we propose a user-reserving management model that can improve the user 's service quality without exposing the information used in the cloud environment to a third party. In the proposed model, user group is grouped into virtual environment so that third party can not handle user's privacy information among data processed in various cloud environments, and then identity property and access control policy are processed by block chain.
