웹에는 방대한 양의 정보가 있지만 현재 그 활용은 제한적이다. 본 연구는 기존에 PC를 통해서만 접근 가능했던 웹 정보를 TV나 모바일 기기를 통해서 볼 수 있게 함으로써, 사용자로 하여금 시공간의 제약으로부터 자유로운 정보 환경을 제공하려는 취지에서 수행되었다. 현재의 웹 정보를 TV나 모바일 기기와 같은 일상적인 매체를 통해서도 활용할 수 있기 위해서는 각 디바이스의 화면에 적합하게 필터링과 요약을 통해 재구성하는 기술이 요구된다. 본 논문에서는 자연어처리 기술에 기반하여 온라인 뉴스 페이지를 개인 디바이스에 적합한 형태로 내용과 레이아웃을 재구성하는 시스템인 ONASys(Online News Adaptation System) 에 대해 소개한다. ONASys는 공간적, 내용적 속성을 이용하여 웹페이지 상의 중요 정보를 선별하는 #컨텐츠 필터링 모듈#, 패턴의 분석과 공기 정보를 통한 문법적 주 요소 인식을 통해 문장을 하는 #문장 요약 모듈#, 제목과 문장의 연관성을 통하여 문장의 중요도를 판단하는 #중요도 결정 모듈#로 구성된다.

Substructuring-based hierarchical approach for design analysis and optimization of structural frames is presented in this study. The conceptual framework of this method is in the hierarchical modeling for design processes as well as structural systems and the methodology combining substructuring analysis and multilevel optimization. Mathematical models for analysis and synthesis are established on the common basis of substructuring systems. Modularized behavioral analysis, design sensitivity analysis and optimization are linked and integrated on the mathematical and structural basis of substructuring. Substructures are coordinated with the active constraints for system level and the weight ratio criteria. Numerical examples for test frames show the validity and effectiveness of the present approach.

We propose the various Telemedicine applications using collaborative PACS environment. Traditionally, almost all medical images have been printed on radiological films. These films are expensive to produce and easy to misplace and usually only one copy exists, thus limiting the number of persons who have simultaneous access to the images. But the merit of this system including PACS(Picture Archiving and Communications System ) is very many which are small depository, low maintenance expense, good efficience(storage, speed) and good flexibility but the development costs is higher. This research has been done creating multimedia-based Telemedicine system for home PCs in network environment. Most of Telemedicine used hardware and exclusive line of high cost as CATV broadcasting technique. But this system will contribute to change the Home-PC for better use of collaborations among doctor and patients through various modes of interactions in cyberspace.

Emergency response of fire prevention manager has an effect on decisive emergency exit behavior of customer who is not accustomed to emergency response in a large-scale shopping department on fire. Especially enclosed stairways in a large scale store are usually located in back space where is impossible for customer to access. Therefore, speedy emergency exit inducement by fire prevention manager is needed for the customer's safe egress. The object of study is to analyse the factors affecting egress behavior and emergency response of fire prevention manager in respect of fire prevention management.

In this paper, proposes the monitoring system it will be able to trace the executed of each threads in OpenMP based a parallel program. The monitoring system of existing in uses each threads label information and the analysis technique which uses the access-history was most. This has the problem which raises the time and space complexity which is caused by with massive information creation. In this paper, only the thread which includes interest information it creates tracking information with the target. And it provides information which is intuitive to the user it provides the visualization system for to a same time. The visualization model is composed the images-information of a base. This does to be it will be able to understandable a program execute situation using an image processing technique. Therefore, this paper provides the parallel program an effective debugging environment.

Recently, there are lots of research work on fuzzy Information theory for many practlcal applications. As the fuzzy control systems become to be sophisticated, they demand more fuzzy parameters, membership functions and fuzzy Inference rules. Eventually, they need effective parallel computing architectures to implement those complex fuzzy inference rules. In this paper, a optical fuzzy Inference system based on 2-D spatial light modulator and digital image board Is Implemented as a new approach for real-time parallel fuzzy computing system. From its good experimental results on the practical fuzzy airconditioner system, a new real-time Opto Fuzzy Inference system Is suggested.

The national topographic basedata should meet a variety of user requirements. To generate, maintain and handle the national topographic basedata in economic and effective way, the nationally supported research works on data model, structure and feature classification system should be intensively undertaken by government agency, research institute and university. This paper presents the technical definitions of conceptual and logical model for proposed data model representing digital map data. The key aspects of the proposed data model are flexibility for accommodating user requirements as well as step-by-step approach for modification as necessary m recent future. Conclusively, the proposed data model is a transitional data model between simple graphical model and object oriented data model.

Detection of water bodies in land surface is an essential part of disaster monitoring, such as flood, storm surge, and tsunami, and plays an important role in analyzing spatial and temporal variation of water cycle. In this study, a quantitative comparison of different thresholding-based methods for water body detection and their applicability to Kompsat-5 SAR data were presented. In addition, the effect of speckle filtering on the detection result was analyzed. Furthermore, the variations of threshold values by the proportion of the water body area in the whole image were quantitatively evaluated. In order to improve the binary classification performance, a new water body detection algorithm based on the bimodality test and the majority filtering is presented.

A well designed disabled home needs to consider various design principles and variables. It should consider not only physical accessibility but also psychological aspects. Previous research studies have shown that barrier-free/universal designs which were primarily focused on physical access and usage of facilities and building operations. This research paper will examine, a selection of refurbished disabled homes, introduced by the Korean Disabled People's Development Institutes in 2013. The plan samples are to be analyzed using the Visual Access and Exposure spatial analysis program coupled with supporting information extracted from consultations and feedback from experienced professional disabled home staff members. This research paper aims to propose the usage and viability of VAE Analysis in the design and planning of disabled home layouts. The purpose of this study is to specify the differences in visual spatial relationships between the plans before and after refurbishment in accordance to staff and user requirements. This will ensure a bettered environment for the users and ensuring an optimized of spatial programming and building operation and usage.

In this paper, we proposed a method for representing local facial features based on LDP (Local Directional Pattern). To represent both PFF (Permanent Facial Features) and TFF (Transient Facial Features) effectively, the proposed method configure local facial feature vectors based on overlapped blocks for each facial feature in the forms of various size and shape. There are three advantages - it take advantages of geometric feature based method; it shows robustness about detection error using movement characteristics of each facial feature; and it shows reduced sampling error because maintain spatial information caused by block size variability. Proposed method shows better classification accuracy and reduced amount of calculation than existing methods.
