The purpose of this study is to analyze science fields and content elements of the science reports in a web portal site of Republic of Korea in view of scientific literacy. The main results of the analysis on the 679 reports sampled in a year are as follows. First, 506 reports in 46 fields were identified. Reports about technology and earth science occupies 16% respectively, and life science occupies 13%, medical science 4%, chemistry, company, others 3% and physics 1%. Almost reports show technology as associate field. Second, the frequency rate of reports including scientific literacy content elements is 52%. Reports related to 'physics' and 'chemistry' as dominant fields show relatively high rate in scientific literacy elements. The element, 'social context' is included in about 96% of the reports. Both 'data and statistics' and 'application' show relatively low rate and large gaps according to dominant fields. A few concluding remarks and proposals follow from these results. First, as almost science reports show the nature of integrated science, scientific literacy acquisition through science reports in internet requires the integrated scientific view. Especially most science reports includes the contents related to technology or medical science, so the point of view in the science-technological literacy is required. Second, the scientific literacy content elements in reports show various rates according to dominant fields. Therefore, science reports need to complement the deficient content elements to carry out the role of science reports as scientific literacy sources.

의생명과학분야가 계속 발전됨에 따라 매일 평균 3천여 편에 달하는 방대한 양의 의생명과학분야 문헌들이 나오고 있다. 많은 연구가 진행될수록, 새로이 규명된 관계를 습득하고 체계화하는 일이 연구자와 의료계 종사자들에게 더 중요해지고 있다. 하지만 현재로서는 의생명과학분야에 어느 정도의 지식이 있는 사람이 직접 논문을 읽고 해당 논문에서 밝히고 있는 정보를 정리해야만 하는 상황이며, 이로는 기하급수적으로 쌓이는 정보의 양을 대처하기 어렵다. 이를 해결하기 위해 본 논문에서는 기계 학습을 통한 생명의료 객체관계 자동추출 연구를 이용하여 의생명과학분야의 정보를 체계화 하고자 한다. 본 논문에서는 돌연변이와 약물이 함께 등장하는 논문을 뽑아내어 글을 자연어 문장 단위로 나누었다. 추출한 돌연변이와 약물 간의 관계를 직접 사람에 의해 참거짓을 판명하였고, 해당 데이터셋을 기계학습에 이용하여 돌연변이와 약물 간의 관계를 학습시켰다. 최종적으로 GoogleNews의 기사들로 기학습된 워드임베딩, 의생명과학분야 문헌들을 이용하여 기학습된 워드임베딩을 이용하여 학습의 성능을 비교하였고, 의생명과학-문맥 특이적인 워드임베딩이 갖는 강점을 보고한다. 해당 연구를 통해 실제로 논문을 읽지 않고도 의생명과학분야 논문의 핵심적인 내용을 뽑아내는 자동화 시스템을 구축하는 데에 이바지하고, 의생명공학 연구자들의 연구에 핵심적인 도움이 되는 디딤돌이 되고자 한다.

I would like to trace back periodic social trend by searching if regular performance might have reflected on social trend on its theme by analyzing theme trend of The National Dance Company of Korea, Dance Company of Seoul city, Dance Company of KyungKi-Do and to provide the meaningful results for further study by checking if the theme of dancing performance is in relation with social structure. To perform this research, I had studied on previous thesis and reference books. For example, I selected three groups, of The National Dance Company of Korea, Dance Company of Seoul city, Dance Company of KyungKi-Do, to research their theme of regular performance through checking previous thesis related to, performance material, news articles, pamphlets from beginning to present. How to analyze is being proceeded from foundation of dancing company to present according to Kim Byungseok's classification method, which was consistently used for searching theme trend from previous study as below; 1) Theme based on traditional conscious,2) Theme based on Literature, 3) Theme based on Historic issues, 4) Theme based on abstract, 5) Theme based on reality, 6)Theme based on social issues.

There are many internet users who collect the public opinions and express their opinions for internet news or blog articles through the replying comment on online community. But, it is hard to search and explore useful messages on web blogs since most of web blog systems show articles and their comments to the form of sequential list. Also, spam and malicious comments have become social problems as the internet users increase. In this paper, we propose a clustering and visualizing system for responding comments on large-scale weblogs, namely 'Daum AGORA,' using similarity analysis. Our system shows the comment clustering result as a simple screen view. Our system also detects spam comments using Needleman-Wunsch algorithm that is a well-known algorithm in bioinformatics.

As Internet users increasingly consume news through the Internet, Internet portals face criticism that they are quickening the softening of public news and molding public opinions. Some portals have started to provide newscast services that directly connect the press, not grouping news sources on their own standards. This study aims to clarify how news grouping models and newscast models are different in terms of news softening and agenda setting. Specifically, authors conduct a content analysis on time-specific news content provided by top three portals-Naver, Daum, and Nate. By doing so, this study examines characteristics of news service models of Internet portals and their social and political implications. According to our study, the softening and tabloidization of portal news had not been improved even after adopting the newscast model. Therefore, portal journalism should be reorganized as a way to circulate healthy and qualified news content.

For analyzing and prediction of economic trends, it is necessary to collect particular economic news and stock data. Typical Web crawler to analyze the page content, collects document and extracts URL automatically. On the other hand there are forms of crawler that can collect only document of a particular topic. In order to collect economic news on a particular Web site, we need to design a crawler which could directly analyze its structure and gather data from it. The wrapper-based web crawler design is required. In this paper, we design a crawler wrapper for Economic news analysis system based on big data and implemented to collect data. we collect the data which stock data, sales data from USA auto market since 2000 with wrapper-based crawler. USA and South Korea's economic news data are also collected by wrapper-based crawler. To determining the data update frequency on the site. And periodically updated. We remove duplicate data and build a structured data set for next analysis. Primary to remove the noise data, such as advertising and public relations, etc.

With the advance of function of smart phone system and internet services, mobile trade grows more popular in the area of e-business or banking. These environmental changes, it makes the needs of authorized certificates. Authorized certificate is not only important in these days but also future society. In 2015, 27 millions of Korean people used public key certificate, but most of them does not know the details on the public key certificate. Therefore, in this paper, we explain and investigate the characteristics on the public certificate and explain the relation ship between authorized certificate and public key encrytion. By investigating several papers, internet data, newspapers and books, we found the historical changes, substantial aspects, the encryption systems on the authorized certificate. Also we study the pros and cons of authorized certificate. Finally we predict the number of issued authorized certificate for the future society based on nonparametric statistical method.

In this paper, the news coverage of Chosun Art Exhibition(鮮展) in the Japanese occupational era were analyzed by the discourse analysis technique. Japan was advocated the slogan of 'escape from the asia go to the west' and calls itself as western civilized nations during Japanese occupational era. Japan's colonial rule in Asia has created a Japanese orientalism that Japan is considered as developed, and the other Asian countries are considered underdeveloped countries. The media discourse of Chosun Art Exhibition make to believe that the 'backwardness' of Korean local color arts, unlike the 'colonial superiority' of Japanese arts. In the analysis of the newspapers, Maeil Shinbo and Donga Ilbo, Japan recognize Korean arts as the 'assimilation' of Japanese arts, but with the other hand recognize the 'exclusion' of Japanese arts had a dual-in. Especially, Donga Ilbo has a vision of orientalism on the one hand and has a nationalistic perspective on the other hand.
