In this study, pathfinder network analysis has been carried out to identify subject domains of documents which cited articles in the ASIST Proceedings. This represents how articles in the ASIST Proceedings are flowed and used in what subjects areas. For this analysis, 240 documents were selected through a search of the Scopus database. The complete linkage clustering method was used to draw out 16 clusters from 240 documents. Through MDS and pathfinder network analysis, knowledge networks of clusters have been produced. As a result. articles in the ASIST Proceedings relating to knowledge management, bibliometrics, information retrieval and digital libraries have been cited actively by other publications. The most frequent citation flow type of ASIST proceedings was citation from proceedings(ASIST) to reviews(ARIST), via journals, and the most popular subject areas related to documents were bibliometrics.

With development of the methodology for the selection of future emerging research and technology subject it will reach and the research for the concrete item selection which leads is propelled. It uses scientometrics objective indexes and accomplished information analysis of highly cited paper(HCP) & Clustering from the present paper. Scopus data about under using it accomplishes information analysis of construction traffic fields. It selects emerging research of construction traffic fields, it compares a national for technical trend.

Companies have developed local database without purpose of cooperation with others in the same category. That's because the cooperative work would cause cost in standardization, management, and usage of overlapping data. Therefore this paper proposes a system supporting an dynamic user interface for the sake of convenience of meta-data transformation and its users. The cooperative system will be able to connect companies together and minimize overlapping data by standardizing them. Eventually, the system will have an effect on cost-cutting and improve efficiency of maintenance and management.

Surveyors has desired eagerly surveying technology and equipments which are able to acquire a lot of data easily, quickly and precisely. Laser has the merits that is able to obtain a large number of measurements with high precision in a short time and one of concrete realizations is a terrestrial laser scanner called Terrestrial LiDAR. This paper describes 3D modelling of a old architecture which was conducted using a Z-F laser system and the result of positioning analysis. Use of terrestrial laser scanner is much more efficient than existing photogrammetry in measuring and database constructing for preservation and restoration of cultural assets as well as for deformation monitoring and safety diagnosis of structures.

Regional construction management offices and local administrations have set up the fundamental plan for river improvement works respectively for the national level, and local 1st and 2nd level rivers for the purpose of river management, use, development, disaster mitigation, and water quality conservation on the annual basis. Enormous number of reports and river registers have been produced. However, the products before 2003 are not well managed so that frequent users have toubles in using these information. In this paper, Information Service System on the Fundamental Planning Report for River Improvement Works developed in 2005 is introduced.

Recently, the computer vision has been applied to many automation fields. Especially, this paper presents a maritime traffic detection system using computer vision since the high level information can be obtained using obtained area information. The high level informations are obtained such as speed, queueing length, queueing time, ship size, and ship kind. To get ship speed, the two detection lines are set on the predetermined screen position. The speed is obtained the passing time and the predetermined distance between the first and second detection line on the screen. Also, queueing length and time are gotten using screen position of ship. Furthermore, the size and kind of ship are calculated using the ship database and camera calibration data. This developed system contributes to reduce the traffic accidents on the coast. Futhermore, the more information can be extracted using obtained area information.

This paper introduces TIGS(Touring Information Guidance System) which provides information of the southwestern area of korea with faster access time than the human service. This system is designed specifically for a traveler. This TIGS provides tourists the informations such as destination, current map information, touring courses according to schedules, traffic information and lodging information. furthermore, this system is implemented with touchscreen for the user to apply easily. The shortest path algorithm is applied to schedule the touring courses to refute the time and the cost. The map is raster manner to represent southwestern area of korea instead of vectorial manner. If this developed system should be established in the public space such as station, airport, and bus station, touring will be more comfortable, the total income will more increase. Also, this system can be easily applied to different local area.

We develope plasma monitoring system which detect plasma signals and store them for Laser welding quality evaluation and analysis using photo detector. The most fundamental and important aspects in such a system are signal restoration fidelity, noise immunity and noise cancelation capability. In this paper, we propose implementation method using distribute processing structure and hybrid digital communication for high noise cancelation capability, immunity and signal fidelity which are poorly presented in other researches. Lab experimental results and welding experimental results show a effectiveness of proposed method and plasma data is stored with 256 kbps without any communication error. we are implementing various welding defect recognition algorithm in this system.

A new query model is required to match requirements of stream-based applications such as patient monitoring system, since traditional DBMSs are not designed to provide continuous queries over stream data. In the patient monitoring system, there are many types of biomedical signals such as blood pressure and temperature, and these signals gathered by biomedical sensors should be treated as a stream, that is an ordered set of signals. In this paper, we categorized all possible queries to be used in patient monitoring system by four types of queries. Then, we have proposed a new sliding window query model which is capable of expressing these four types of queries.
