원활한 의사소통을 위해서는 문장들을 연결하여 흐름을 조직하고 말로 산출하고 전체적인 의미를 파악할 수 있어야 한다. 이야기는 이러한 문장들이 연결되어있는 것으로, 종속적이거나 나열적인 이야기 특성은 의사소통장애인의 이야기 이해와 산출의 수행에 영향을 미칠 수 있다. 본 연구에서는 이야기 특성에 따른 유창성 실어증환자의 이야기 이해 및 산출의 능력을 알아보고, 이해과제 수행이 산출과제에 미치는 영향을 분석해보았다. 이야기 종류로는 시간적 나열 이야기와 인과적 관계 이야기, 유머가 있는 이야기를 사용하였으며, 사실적 정보, 텍스트 추론, 빠진 정보추론 등 세 가지의 이해과제를 통하여 이해 능력을 측정하였다. 산출능력은 이해과제 전과 후에 CIU 비율로 질적인 측면을 측정하고, 분당어절 수를 이용하여 양적인 측면을 분석하였다. 그 결과 이해측면은 세 가지 이야기 모두 사실적 정보에 대한 이해 능력이 상대적으로 좋았으며, 오류의 형태는 추론오류가 가장 많이 나타났다. 산출에서는 인과적 관계이야기에서의 CIU 비율이 가장 높았고, 이해과제 전, 후의 차이를 비교한 결과, CIU 비율은 변화하지 않았으나, 분당 어절수에서는 증가하고 있음을 보여주었다. 이야기의 종류에 따라서 유창성 실어증화자의 산출과제의 수행수준은 다르게 나타났다. 그리고 이해과제의 수행이 산출과제에서 양적인 증가는 가져왔으나 질적인 수준에는 아무런 영향을 미치지 않았다.

Earlier program plagiarism check systems are performed by using simple text, attribute or token string base on match techniques. They have difficulties in checking program styles which have nothing to do with program syntax such as indentation, spacing and comments. This paper introduces a plagiarism check model which compares syntax-trees for the given programs. By using syntax-trees, this system can overcome the weekness of filtering program styles and have advantage of comparing the structure of programs by syntax and semantic analysis. Our study introduces syntactic tree creation, unparsing and similarity check algorithms about C/C++ program plagiarism checking for internet cyber education and estimate plagiarism pattern.

There are many types of seam tracking methods actually used in industrial spot. Lately, Non-contact sensor technics are mostly used because non-contact sensor has more advantage than contact sensor in many parts. This paper also concerned about fiber sensor a kind of non-contact sensor. X-Y robot and fiber sensor scan the seam tracking to be weld. After scanning, X-Y robot moves the first working point of being scanned and welding starts automatically. It makes an experiment on some types of Seam tracking like straight line tracking, leaned line tracking and curved line tracking to confirm how well the fibers sensor tracks the seam pass to be weld. And the seam pass that had been tracked was welded by inverter $CO_2$ voiding machine.

This paper presents design of an advertising E-commerce (electronic commerce) serve. using push technology which provides clients with multimedia information such as text, audio and video according to their setting information. In the most of existing E-commerce system, users visit the web site in person, see and buy goods. In this paper we show the new E-commerce format: Clients select a field of advertisement of what they want to see on the browser, then EC server sends the clients moving advertisements at regular intervals. Subsequently, the users see advertisements and buy goods. The server of this system was designed using push server that saves moving advertisements in the database and sends the user-specific advertisements to users. The system designed in this study is very an active system contrary to existing passive E-commerce systems.

The SMS(Short Message Service) in Mobile phone is a service that a text message by 80byte is transmitted and received. Recently it's used instead of voice calls. In this paper, We investigate how you take advantage of the SMS for searching information without simply as a means of voice call, and how much efficiency does the SMS have in Location Information Retrieval Services on LBS(Location-based service). Based on the previous topics, we design the information retrieval system using SMS for solveing the rates issue by existing wireless Internet access, and propose the possibility as new forms of content services.

Lee Sang, a poet and a architect, made new experimental poems that was influenced by quantum mechanics and theory of relativity that were published in the early 1900's, and he showed his new view of the world that transcended time and space limit through his poems. In this essay, I studied and analyzed on the links between his view of the world and modern design view with as the central figure his text, 'A Written Promise of The Line' The result is that he fellow the cyclic world view which the world consisted of cycles within cycles, of immense duration and the scientific view of the world which the universe and me are one flesh.

현대 과학 기술은 개개의 분야의 고유성과 특성이 점차 모호해지고 여타 분야와의 접목 내지는 응용의 발판을 넓혀 점차 실용화하는 추세이다. 특히 경제성과 밀접한 관련이 있는 엔지니어링 분야가 더욱 그러하다. 일상생활에서 사용되는 컴퓨터의 진보는 그간 학문적인 연구에 소요되었던 시간을 단축시켰으며 연산가능 범위를 확대하였고 이것을 바탕으로 우리는 좀더 세밀하고 정확한 진단과 예측이 가능해졌다. 이는 엔지니어들이 갖추어야할 지식체계에도 영향을 주어 과거 배타적이며 폐쇄적인 업무성향을 개방적이고 공유 가능한 대상으로 변모가능하게 되었다는 점에서 의의가 크다. 특히 정보 전달의 측면에서 보면 최근 부각되고 있는 그래픽적 요소를 가미한 해석프로그램을 주목해야만 한다. 일반적인 데이터 나열이나 조작 시에 사용되던 텍스트 기법이 다이얼로그 상자를 통해 좀더 인터렉티브한 환경으로 바뀌었고 현재는 이러한 내용을 그래픽적인 환경으로 재해석하고자 하고 있다. 바로 이러한 노력의 일환으로 본 논문 역시 그래픽 시뮬레이터 개발에 관해 다루게 되었다. 본 논문에서는 그래픽이란 주제를 좀더 심층적으로 다루어 사용자 정의 타입의 단계까지 논함으로써 앞으로 나아가야 할 방향을 제시해 보고자 한다.

The skyline query is one of the effective methods to deal with the large amounts and multi-dimensional data set. By utilizing the concept of 'dominate' the skyline query can pinpoint the target data so that the dominated ones, about 95% of them, can efficiently be excluded as an unnecessary data. Most of the skyline query algorithms, however, have been developed in terms of the numerical data set. This paper pioneers an entirely new domain, the categorical data, on which the corresponding ranking measures for the skyline queries are suggested. In the experiment, the ACM Computing Classification System has been exploited to which our methods are significantly represented with respect to performance thresholds such as the processing time and precision ratio, etc.

Weblog is one of the most spread web services. The content of the weblog includes daily events and emotions. If we collect personal information using mobile devices and create a weblog, user can create their own weblog easily. Some researchers already developed systems that created weblog in mobile environment. In this paper, user's activity is inferred from personal information in mobile device. The inferred activities and story generation engine are used to generate text for creating a weblog. Finally, the text, photographs and user's movement in Google Map are integrated into a weblog.
