  • The purpose of this study was to analyze the perceptions of disabled sports that were reported the newspapers using semantic network analysis method. for this purpose, 745 news articles were selected from 21 source in Naver news searching engine. The main keyword for searching on newspapers was 'disabled sports'. Krkwic software was used for keyword cleansing and co-occurrence of text to text matrix in frequencies. Centrality indices that are degree, between and eigenvector, were used to analyze the perceptions of disabled sports from Netminer 4.0 for semantic network analysis. The conclusion of overall results from this study are follows; First, the core keyword of disabled sports in newspapers are 'impression', 'challenge', 'festival', 'dream' and hope. And there is different concepts of cognition among types of disability. Second, there are two elements on the perceptions of disabled sports from reported newspapers; sports performance and emotional. Specifically, main stream of keyword were 'Paralympics' and 'Special Olympics' on sports performance element and 'impressive' and 'challenge' in emotion element.

  • 지난6월 1일 한국과학기술 연구소 강당에서 「과학기술과 정신문화」라는 주제로 심포지움이 열렸다. 한국과학기술진흥재단이 주최한 이 심포지움에는 국내과학기술인과 문학인 등 관심있는 인사 200여명이 참석한 가운데 주제발표에 이어 열띤 공방설전의 선투도 볼 수 있었다. 과진 김립삼 부이사장은 개회사를 통해 이 심포지움은 「엄청난 도전의 의의」를 갖는다고 말하고 장자의 천지편 「기심」,「기사」의 풀이와 아인슈타인의 인간의 alogical을 지적했다. 오늘날 근대화 과정에서 기능분화, 전문화. 세분화의 가속화 파괴와 분열 등 현대문명의 위기에서 인간이란 ,행복이란 ,아름다움이란, 문학적 해답을..과학자와 문학자가 현대사회가 지니는 고민에 해답할 의무가 있다고 했다. 이 심포지움이 공통대화의 광장을 마련함으로 과학과 문학이라는 현대문명의 양거보잉 공통의 이해를 가짐으로 새문화창조의 길잡이가 될 수 있기를 바라는 마음 간절하다. 이날 최형섭 과학기술처장관의 축사, 박종화 학술원 원장의 격려사에 이어 다섯분의 발표가 있었고 참석자 토론이 있었다. 이번에 지면 관계로 일부만 실었다

  • The study was applied to context window sizes and weighting method to obtain the best performance of word sense disambiguation using support vector machine. The context window sizes were used to a 3-word, sentence, 50-bytes, and document window around the targeted word. The weighting methods were used to Binary, Term Frequency(TF), TF ${\times}$ Inverse Document Frequency(IDF), and Log TF ${\times}$ IDF. As a result, the performance of 50-bytes in the context window size was best. The Binary weighting method showed the best performance.

  • 본 연구는 우리나라 디자인학분야 5개 학회(협회)지의 2002년분에 인용된 3,046개 문헌을 인용문헌의 형태별, 발행지별, 발행년도별, 주제별로 분석하여 디자인학분야 연구자의 문헌 이용행태와 문헌의 이용가치 감소현상 즉 반감기를 측정하였다. 연구결과 디자인학분야 연구자들은 단행본(62.5%), 학술잡지기사(21.8%), 논문(10.8%), 보고서(2.9%), 기타(2%)순으로 많이 이용하였으며, 단행본의 인용이 현저히 많은 것으로 자료 형태별 이용에 있어 국내 디자인학분야 연구자의 연구활동이 국내 사회과학, 미술분야와 유사하다고 볼 수 있다. 발행지별로 분석한 결과는 국내 디자인학분야 연구자들이 국내문헌을 해외문헌보다 2.5배정도 많이 이용한 것으로 국내문헌에 많이 의존하는 것으로 분석되었다. 이것은 해외문헌을 국내문헌보다 2배정도 많이 이용한 것으로 분석된 사회과학분야의 선행연구와 비교할 때 디자인학분야에서는 정반대의 현상을 보이는 것이나 4배정도 국내문헌을 많이 이용한 것으로 분석된 미술분야의 선행연구와는 유사한 결과를 나타내는 것이다. 디자인학분야 문헌의 반감기는 5.75년이었으며, 자료형태별 반감기는 단행본(6.64년), 논문(5.97년), 학술잡지기사 (4.55년), 기타(3.73년), 보고서(3.41년) 순으로 분석되었고, 발행지별 반감기는 해외문헌(9.1년), 국내문헌(5.1년)순으로 분석되었다. 또한 타주제와의 관계분석에 있어 경영학, 건축술, 공학 등과 긴밀한 관계를 맺고 있는 것으로 디자인학이 단순히 미를 추구하는 것이 아니라 산업경쟁력 증진의 도구로서 존재한다는 것을 알 수 있다.

  • In this study, we investigate the science and mathematics articles in Hansungsunbo and Hansungjubo which are the first modernistic newspapers in Korea. Hansungsunbo was published from October 31, 1883 to December 4, 1884 and Hansungjubo was issued from January 25, 1886 to July, 1888. While these papers were published, Korea had concluded a treaty with America(1882), England(1883), Germany(1883), Russia, and France(1884). Therefore, Korea had a lot of problems with commercial relations, the civilization and enlightenment of the Korean society. In this situation, some leaders who had the enlightenment thought published these two papers in order to inform the Korean people of the worldwide news on the politics, economy, history, science and technology, and so on. In this paper, we bring up the title and the contents on the science articles and the mathematics test problems of 'Dongmoonguan' and 'Chunjinmoobi School'.

  • The purpose of this study is to investigate and analyze the obsolescence of documents according to their dates, types and locations of publication. The main results are as follows : The half-life of monographs is 12.09 years while those of articles and research papers are 9.68 and 8.93 years, respectively. Moreover, documents are most often cited by researchers within two years since their publication. Lastly, but not the least, the estimated weeding points for monographs, articles, and research papers, assuming that their weeding points have been realized when their accumulated citation rates reach 90%, are 40.15, 32.15, and 29.65 years, respectively.

  • Graphene, called the "dream material" is drawing attention as a groundbreaking new material that will lead the era of the 4th Industrial Revolution. Graphene has high strength, excellent electrical and thermal conductivity, excellent optical permeability, and excellent gas barrier properties. In this paper, as the South Korean government recently announced Green New Deal and Digital New Deal policy, we analyze graphene technology, which is also attracting attention for its application to Corona 19 biosensor, to understand its national R&D trend and knowledge structure, and to explore the possibility of its application. Firstly, 4,054 cases of national R&D project information for the last 10 years are collected from the National Science & Technology Information Service(NTIS) to analyze the trend of graphene-related R&D. Besides, projects classified as green technology are analyzed concerning the government's Green New Deal policy. Secondly, text mining analysis is conducted by collecting 500 recent graphene-related articles from e-newspapers. According to the analysis, the field with the largest number of projects was found to be high-efficiency secondary battery technology, and the proportion of total research funds was also the highest. It is expected that South Korea will lead the development of graphene technology in the future to become a world leader in diverse industries including electric vehicles, cellular phone batteries, next-generation semiconductors, 5G, and biosensors.

  • The purpose of this study was to investigate how a science magazine played a role in filling the gap between scientists and the general public, and how it contributed to science popularization. We analyzed the linguistic features of the texts used in a science magazine. We used 12 articles (six written by journalists, and six written by scientists) from the Science Donga. Register analysis was conducted in order to define the linguistic features of the texts in terms of ideational meaning, interpersonal meaning and, textual meaning. Results of this study are as follows: (1) the articles written by journalists used a higher mental and verbal processes in which the conversations and thoughts of scientists were expressed. (2) Human agents were relatively explicit in the journalists' articles. However, they were implicit or omitted in the articles of scientists. (3) Interrogative sentences and inclusive imperative sentences, and even omissions were frequently found in the journalists' articles whereas scientists' articles mainly used declarative statements. (4) The clause density of journalist' articles and scientists' were similarly lower than that of science textbooks. (5) The information structure revealed by the patterns of Theme and Rheme that the journalists' articles used in science magazines was simpler than that of science textbooks, while the structure of scientists' articles was more complex than that of journalists'. Based on the linguistic features of the texts used in science magazines, we found that a science magazine contributes to science popularization in two faces: One is in that the articles of journalists present science contents in a way that the readers can follow with ease and feel well-acquainted. The other is that the modified articles of scientists help the general public get familiar with the culuture of science in terms of use of science language.
