In recent creativity becomes a new request in the knowledge and information age. Robot programming education is an effective teaching method for improvement of creativity. Existing robot programming tools includes text-based or GUI-based development environment. Most of programming tools provide a simple tutorial system without interactive activity for beginners. In this paper, we propose an online robot programming education system based on web2.0, which embedded collaborative code creating tool, interactive tutorial chat and video conference tool to support collaborative code creating via web 2.0. Knowledge sharing tool allows users to share their collaborative source code. Besides, it makes users gained the experience and knowledge of program designing efficiently.

문서 교정기에서 문맥의존 철자오류를 교정하는 방법은 크게 규칙을 이용한 방법과 통계 정보를 이용한 방법으로 나뉜다. 한국어와 달리 영어는 오래전부터 통계 모형에 기반을 둔 문맥의존 철자오류 교정 연구가 활발히 이루어졌다. 그러나 대부분 연구가 문맥의존 철자오류 교정 문제를 특정 어휘 쌍을 이용한 분류 문제로 간주하기 때문에 실제 응용에는 한계가 있다. 또한, 대규모 말뭉치에서 추출한 통계 정보를 이용하지만, 통계 정보 자체에 오류가 있을 경우를 고려하지 않았다. 본 논문에서는 텍스트에 포함된 모든 단어에 대하여 문맥의존 철자오류 여부를 판단하고, 해당 단어가 오류일 경우 대치어를 제시하는 영어 문맥의존 철자오류 교정 기법을 제안한다. 또한, 통계 정보의 오류가 문맥의존 철자오류 교정에 미치는 영향과 오류 발생률의 변화가 철자오류 검색과 교정의 정확도와 재현율에 미치는 영향을 분석한다. 구글 웹데이터에서 추출한 통계 정보를 바탕으로 통계 모형을 구성하고 평가를 위해 브라운 말뭉치에서 무작위로 2,000문장을 추출하여 무작위로 문맥의존 철자오류를 생성하였다. 실험결과, 문맥의존 철자오류 검색의 정확도와 재현율은 각각 98.72%, 95.79%였으며, 문맥의존 철자오류 교정의 정확도와 재현률은 각각 71.94%, 69.81%였다.

In recent years, the need of the education for the Internet ethics is emphasized as the number of offenses committed by juveniles is increasing. So many researches on the methodologies about educating the Internet ethics have been being performed But, those are not competent to make young people inspire the sense of ethics in the cyber-space because they get trained by the cramming system of education with a textbook in their schools. In this paper, we developed a web-based learning model and an learning system including various multimedia materials that induce the learners for ethics to study actively. And then we applied our system to school education for the Internet ethics, and verified the effectiveness of our learning model and system.

GPS, ARPA, AIS, NAVTEX, VHF as modern aids-to-navigation equipments improve the safe navigation and help to reach a reduction in marine accidents by providing images, numeric values, texts, audio-based information for mates, However, we also noticed that it's complicate and difficult for a mate to acquire and analyze such information from these devices while he should devote himself to bridge watchkeeping especially in the urgent situation. Language is another way to get information and free the eyes and hands, so, to solve the problem above, we are trying to propose a new aids-to-navigation system, which can understand and merge multimedia marine safety information, analyze the situation and provide the necessary information in language. In this paper, we try to fuse data of ARPA/AIS using Euclidean distance for providing integrated information.

The purpose of this paper is to analyze storytelling in on-line personal game broadcasting in order to find out unique characteristics of on-line personal game broadcasting. This study selects Youtube channel and as classic cases of on-line personal game broadcasting, and analyzes the cases with Bakhtin's theory of carnival. The on-line personal game broadcasting modifies the broadcasting format of mass media externally. Also, the on-line personal game broadcasting internally moves between interior and exterior of the game text in order to create new narrative events. In this process, the polyphonic utterances of the broadcasting host appeared. The reversal of the tragedy and the comedy leads the audience to catharsis.

In this study, we introduce a new way to improve the efficiency of Gait Analysis and promote its usage. This program can be shown in different points of view such as an individual or group patient data. The 'Gate Data Visualization Program' is improving its efficiency by minimizing the margin of error during research and promoting the easy interpretation. In addition, this program is designed to have an easy access, and can be used to develop the most basic medical equipment program to predict a probable disease for patient by collaborating with physicians specializing in neurosurgery.

The news pages provided through the web contain unnecessary information. This causes low performance and inefficiency of the news processing system. In this study, news content extraction methods, which are based on sentence identification and block-level tags news web pages, was suggested. To obtain optimal performance, combinations of these methods were applied. The results showed good performance when using an extraction method which applied the sentence identification and eliminated hyperlink text from web pages. Moreover, this method showed better results when combined with the extraction method which used block-level. Extraction methods, which used sentence identification, were effective for raising the extraction recall ratio.

지금, 세계는 바야흐로 'Social Network Service(이하 SNS)의 시대' 이다. SNS란 '일련의 관계에 의해 모인 사람들 간의 관계망을 특정 체계를 통해 대중에게 제공하는 것' 이라고 할 수 있다. 과거 향우회, 동문회처럼 오프라인에서 존재했던 이러한 관계망이 온라인으로 도입된 것이 현재 SNS라고 일컫는 서비스이다. SNS가 큰 인기를 끌고 정보 사회가 발전함에 따라 SNS의 서비스와 형태도 점차 다양해져 왔다. 특히나 그림 영상 등의 시각적인 요소를 사용한 의사소통과 정보의 공유가 과거 그 어떤 매체보다도 손쉽고 빠르게 이루어지고 있다. 인간의 거의 모든 문화 사회적 활동에 컴퓨터가 기반이 됨으로써, 우리는 점차 텍스트, 사진, 영화, 음악, 가상환경 등과 같은 문화 데이터와 더욱 밀접한 관계에 놓이게 되었으며 이것은 SNS에서도 예외가 아니다. 우리는 더 이상 컴퓨터를 마주하는 것이 아니라 디지털 형식으로 기호화된 문화와 마주하고 있으며, 그 중심에는 시각적인 요소들, 즉 '이미지'가 있다. 이러한 점에 착안하여 본 연구는 'SNS'와 그 이미지들의 특성에 대한 이해를 선행한 뒤, 최근 국내에서 가장 활발한 성장세를 나타내고 있는 SNS인 미투데이 페이스북 이상의 두 서비스의 사례를 분석할 것이다. SNS의 이미지의 정체성, 이미지 표현의 특징과 양상이 어떠한지를 분석하고 SNS에서 사용되는 이미지와 그 의미를 보다 심층적인 관점에서 이해해 보는 것은 SNS를 중심으로 형성되어 있는 관련 업계와 학계에 유의미한 내용을 제공할 것으로 기대된다.

According to the increase of audio and video data utilization, the presentation of multimedia data contents and the work of retrieving, storing and manipulating a multimedia data have been the focus of recent work. The display for multimedia data should retrieve and access the contents easily that users want to present. This study is about the design and implementation of a system to retrieve multimedia data based on the contents of documentation or the caption information of a multimedia data for retrieving documentation including multimedia data. It intends to develop an filtering step to retrieve all of keyword within the caption information of multimedia data and text of a documentation. Also, the system is designed to retrieve a large amount of data quickly using an inverted file structure available for B+ tree.

A description of SGML(Standard Generalized Markup Language) is given together with a detailed description of WIPO Standard ST.32. The benefits of the use of SGML are highlighted-its system Independence and flexibility in building publication systems and full-text databases. A structure of WIPO Standard ST,32 based patent content is defined by DTD(document type definition) written in ST.32, and full-text itself is described with generalized markup depending on DTD. This article explains how to represent a document structure : a hierarchy structure like a entire document, a specific, sub-document, a paragraph, or non-hirarchy structure like a table drawings, or chemical structures. Merits of SGML In patent document processing are also discussed.
