The coast has been known as very vulnerable area. This area has nature disasters such as typhoon, tidal wave, flood and storm almost every year. In this study, coast vulnerable area information management system was developed to manage the coastal facilities and vulnerable area through Web GIS. This system is able to visualize the damage area and support the official work related to coast as efficient DSS(Decision Supporting System). Moreover, the foundation for domestic coast information management is expected by acquiring less cost and time. For this, GIS DB was first constructed by acquiring damage factor data such as typhoon, tidal wave, flood and storm. Then GIS analysis methods and high resolution satellite images are used to possibly present the results of retrieve as table, map, graph, inundation simulation in real time.

This paper describes performance improvement of GPS/DR Integration system using area decision algorithm and vehicle movement information. In GPS signal blockage area, i.e., tunnel and underground parking area, DR sensor errors are accumulated and navigation solution is gradually diverged. We use the car movement information according to moving area to correct the DR sensor error. Also, vehicle movement is decided as stop, straight line, turn and movement changing region through DR sensor data analysis. The car experiment is performed to verify the supposed method. The results show that supposed method provides small position and heading error than previous method.

In Korea, micro-enterprises are in charge of an important part of the common people's economy, but face difficulties such as excessive competition, deteriorating profitability, and concentration of life-oriented industries. In order to solve this problem, the government is providing commercial district analysis services for micro-enterprises. However, the data provided by various organizations is not standardized, and there is a limit to the composition of the service with limited data. In this paper, we propose a method of solving the data consistency problem and linking and analyzing between questionnaire information and commercial district information to expand the data analysis service. The proposed linking methods are three methods: linking the commercial area information and questionnaire information in the same area based on the type of business and area, linking the survey information centered on individual micro-enterprise, and linking a small area of questionnaire information with a large area of commercial district information. The linked commercial district information and questionnaire information can be used in various ways or expanded analysis services. This proposed a method to overcome the limitations of existing commercial district analysis services with questionnaire information and lay the foundation for expanding the commercial district analysis services necessary for micro-enterprises.

Reviewing the outcomes of studies on contemporary information science during some periods and identifying the research area exposed in its studies are essential processes to develop the research and theories of information science and to establish the academic identity of information science. This study seeks to provide the some useful methodological approaches for establishing the research area of information science. The methodological approaches to research area of information science are as follows : (1) normative approach by concepts, definitions, and principles of information science, (2) content analysis of text books, (3) content analysis of curricula of graduate courses, (4) content analysis of graduate disserations or treatises, (5) IIS(Institute of Information Scientists)'s criteria for information science, (6) professors' need assessment, (7) interdisciplinary approach, etc. These are the representative types of methodological approach and have an enough validity and effectiveness in their own way. Therefore I think of that those should be integrately applied to establishing the academic identity of information science.

The aim of this study is propriety review for underground facility surveying on development area of land for housing and efficient management. Because of integration information administration system construction of the nation and development of information technology, construction of Urban information system(UIS) to manage systematically city space is increasingly necessary We manage systematically attribute information for each lot in the development area of land lot housing that it Is connected with NGIS in order to drive gradual computerization of underground facilities and arrange the base of facility management. Review arrangement methods on development area of land for housing makes it to check safety accident of urban and to leading base of urban information. Thus, this study draw the most suitable way through analysis of driving methods and expectation effect from above facts.

This research uses high-resolution satellite images as a source of collecting farmland information. For effectively extract the paddy area, we use texture information and different classify methods to assist the satellite image classification. First, using maximum likelihood classifier to extract paddy information from images. The results show that User Accuracy and Procedure Accuracy of the paddy area can increase from 80.60% to 95.45% and 84.38% to 95.45%. Second, establishing a paddy Knowledge Base and using Knowledge Base Classifier to extract paddy area, and result shows the User Accuracy and Producer Accuracy to be 92.16% and 90.06%. Finally, The result shows we can effectively contribute to the paddy field information extraction from high-resolution satellite images.

This study aims to expand the future study methodology and to develop a methodology of future-oriented curriculum analysis with future skills needs derived from patent analysis. With the case of information security, the methodology is applied to the 16 universities, which have information security department in undergraduate course. From the results, the followings are suggested : 1) for the increasing importance area including hacking, infiltration and PC security, a practical exercise should be emphasized; 2) for the convergence area including security policy, security legislation and OS security, proper faculties should be filed with recruiting field-based experts; 3) for the increasing importance area including professional area including security audit and information security protocol, the advanced curriculum related to graduate level should be provided.

The purpose of this study is to prove that new values for the agricultural food area can be created by combining various big data collected in the agricultural food area and analyzing them in an appropriate analysis method. For this, the analysis techniques generally used were studied, and the use of the big data in the various areas of the current society was explored through practical application instances. In addition, by the current status and analysis instances of the big data use in the agricultural food area, this study was conducted to verify how the new values found were being used.

Optical Character Recognition (OCR) that has been a main research topic of computer vision and artificial intelligence now extend its applications to detection of text area from video or image contents taken by camera devices and retrieval of text information from the area. This paper aims to implement a binarization algorithm that removes user intervention and provides robust performance to outdoor lights by using TopHat algorithm and channel transformation technique. In this study, we particularly concentrate on text information of outdoor signboards and validate our proposed technique using those data.

In this paper, a Radix-8 structure for high-speed FFT is proposed. Even throughput of the Radix-8 FFT is twice than that of the Radix-4 FFT, implementation area of the Radix-8 is larger than that of Radix-4 FFT. But, implementation area of the proposed Radix-8 FFT was reduced by using DA(Distributed Arithmetic) for multiplication. The Verilog-HDL coding results for the proposed FFT structure show 49.2% cell area increment comparison with those of the conventional Radix-4 FFT structure. Namely, to speed up twice, 49.2% of area cost is required. In case of same throughput, power consumption of the proposed structure is reduced by 25.4%.
