웹 문서의 가장 큰 특징 중 하나는 링크 구조이다. 이 링크들을 이용하여 전체 웹 문서를 커다란 하나의 네트워크로 구성할 수 있으며 이러한 네트워크를 분석함으로써 보다 중요한 문서, 보다 유용한 사이트를 찾아낼 수 있다. 전통적인 검색 모델인 벡터 모델의 성능 개선을 위해 이러한 링크 분석 기법을 활용하여 검색 정확도를 향상시키기 위한 방법을 제안한다. 또한 하이퍼 텍스트는 보다 정확한 키워드를 포함할 확률이 높으므로, 이를 가중치 계산에 적용하여 보다 정확한 결과를 산출한다.

The present study performed semantic network analysis of the keywords in the headlines of newspapers to investigate the media coverage of the multidrug-resistant microorganisms(MDROs) which is resistant to antibiotics. For this purpose, 229 news stories on MDROs in 28 newspapers from June 1, 2010 to December 31, 2011 were analyzed. The news stories were gathered from the Korea Press Foundation's news database, KINDS (www.kinds.or.kr) and websites of Korean newspapers. The analysis of the keywords revealed 'superbacteria' appeared most frequently (n=155) followed by 'infection' (n=63) which arouses fear among readers. While network was structured with the keywords such as 'domestic', 'multidrug-resistant microorganisms', 'first', 'antibiotics', 'outbreak' and 'infection', the keywords such as 'MDROs related stocks', 'medical staff', and 'safety' were on the periphery of the network.

The purpose of this study was to investigate how congruently the learning objectives of Earth Science I textbooks match the 2009 revised Earth Science curriculum. For this purpose, we classified the learning objectives of curriculum and textbooks were into three factors including ability, cross-cutting concepts, and behavioral verbs. The text data were analyzed using the semantic network analysis method. The results are as follows. The learning objectives of textbooks with regard to ability factors mainly emphasized the cognitive and affective domain. In addition, the ability of inquiry performance was emphasized in the learning objective of the curriculum. The textbooks used various sub-frame of cross-cutting concepts in comparison with the curriculum. Both textbooks and curriculum used the term 'comprehension' the most as behavioral verbs. However, most behavioral verbs just remained at the level of cognitive system.

The study is to investigate research trends and knowledge structures in the Smart Farm field. To achieve the research purpose, keywords and the relationship among keywords were analyzed targeting 104 Korean academic journals related to the Smart Farm in KCI(Korea Citation Index), and topics were analyzed using the LDA Topic Modeling technique. As a result of the analysis, the main keywords in the Korean Smart Farm-related research field were 'environment', 'system', 'use', 'technology', 'cultivation', etc. The results of Degree, Betweenness, and Eigenvector Centrality were presented. There were 7 topics, such as 'Introduction analysis of Smart Farm', 'Eco-friendly Smart Farm and economic efficiency of Smart Farm', 'Smart Farm platform design', 'Smart Farm production optimization', 'Smart Farm ecosystem', 'Smart Farm system implementation', and 'Government policy for Smart Farm' in the results of Topic Modeling. This study will be expected to serve as basic data for policy development necessary to advance Korean Smart Farm research in the future by examining research trends related to Korean Smart Farm.

국내에서 온라인 커뮤니티는 1990년대 말 인터넷과 개인 PC의 급속한 보급으로 인해 대중화되기 시작했다. 커뮤니티는 이용자 간 활발한 커뮤니케이션을 기반으로 구축되고 있으며 이러한 커뮤니케이션은 일상적인 언어적 맥락을 바탕으로 구성된다. 이러한 커뮤니티의 내용 분석은 연구자의 직관에 의해 수행되기 마련이나 연구대상의 양이 많아질 경우 연구자의 직관만으로는 이를 분석하는데 제약이 있을 수 있다. 네트워크 분석은 이와 같은 문제점을 해결 할 수 있는 방법 중 하나이다. 본 연구는 온라인 임신 Q&A 게시판의 내용적 특성을 살펴보기 위하여 네트워크 분석을 수행하였다. 먼저 수집한 데이터의 전체적인 내용적 특성을 살펴본 후, 게시글 작성자인 임산부의 임신 시기에 따른 게시글의 내용적 특성을 살펴보았다. 분석 결과 임신시기별로 핵심적인 단어의 빈도의 차이가 있었으며 네트워크의 구성 또한 다른 것을 확인하였다. 또한 성별에 따라서도 그 내용적 특성이 다른 것을 살펴 볼 수 있었다.

The words a speaker uses can be regarded as the core, the main issue and a symbolic icon of what he says. Applying this to presidents' addresses of each English literary society in Korea shows that frequency in use and the linkage of words they use in their addresses are value and ideas executive officers pursue. The purpose of this study is to analyze the contents of presidents' addresses introduced in home page of each English literary society in Korea and investigate features and constitution of them each, focusing on analysis of a language network. The results of this study show the features of resemblances and differences of commonly-used words. In addition, these results appear to suggest that they can be also applied to a comparative study between the English literary societies in Korea.

This research analyzed domestic newspapers' agenda setting trend and meaning construction process on the issue of marine environment by year. The research conducted a language network analysis and used R program and Netminer program to analyze four major daily newspapers' news coverages (Dong-A, Joongang, Hanhyoreh, and Kyunghyang) for the last ten years (2005-2014). The results show that the issue of marine environment in Korean media reports are signified in the economic context. For the last ten years, news reports are mainly focused on the 'development' issue of marine environment, without distinction of year. The core key words of the networks are "development", "plan", and "project." However, diverse strategies for 'preservation' are not covered in media reports as a major issue. The importance of effective preservation and reasonable development should be considered in a balanced way. Korean media coverages mainly concentrate on the development issue, and it has a strong influence on considering the marine environment area as an object of development. Future direction and implication of the press reports related to marine environment are discussed.

The purpose of this study is to examine the students' and teachers' perception about the roles and qualifications of teacher librarians. For this purpose, data were collected through survey from students and teachers at secondary schools and the data were analyzed by semantic network analysis. The results of the research are as follows: First, students usually perceived the role of teacher librarians as 'library management', and teachers did as 'reading education'. Second, among the roles of teacher librarians, it was confirmed that students' and teachers' perceptions of 'information literacy instruction and library instruction' were very weak. Third, while the students' perception of the role of a teacher librarian as a 'teaching collaborator' such as 'teaching and learning support' and 'library assisted instruction and collaborative instruction' was weak, teachers recognized the role of teacher librarians as 'teaching collaborators'. Fourth, students and teachers perceived high levels of 'information service', which consists of 'book recommendation and guide activities'. Finally, it was investigated that 'professionalism' plays a central role in the students' and teachers' perception about the qualities of teacher librarians. These results can be used to establish the role of teacher librarians, develop response strategies for students and teachers, and improve their awareness.

This article reports an attempt to perform a similarity analysis on a collection of 25 culinary manuscripts in Chosun periods using a set of quantitative text analysis methods. Historical culinary texts are valuable resources for linguistic, historic, and cultural studies. We consider the similarity of two texts as the distributional similarities of the functional components of the texts. In the case of culinary texts, text elements such as food names, cooking methods, and ingredients are regarded as functional components. We derive the similarity information from the distributional characteristics of the two key functional components, cooking methods and ingredients. The results are also quantified and visualized to achieve a better understanding of the properties of the individual texts and the collection of the texts as a whole.

자바는 설계 때부터 네트워크 상의 운영을 고려하여 설계된 언어이기 때문에 소켓 바인딩과 같은 기능을 제공하고 있고, 또한 TCP/IP 프로토콜과 URL 처리 기능을 제공하고 있는 HTTP(HyperText Transfer Protocol) 프로토콜을 동시에 처리할 수 있기 때문에 WWW 서비스를 연동하는 웹서버를 구축하는데 적합한 언어이다. 현재의 인터넷은 점차적으로 발전하여 수요는 급격히 증가하고 있으나, 많은 사용자로 인해 네트워크의 성능저하와 서버의 처리 능력 한계로 인하여 사용자의 수요를 충족시키지 못하고 있다. 본 논문에서는 인터넷을 이용한 네트워킹 프로그램에 있어 멀티쓰레드를 이용하여 응용프로그램을 작성하기 위한 쓰레드의 개요를 설명하고, 쓰레드를 활용한 풀을 구성하기 위한 제반 사항을 기술한다. 또한, 응용프로그램으로 동적 쓰레드, 서버 복제, 쓰레드 풀 웹 서버를 구현하여 성능을 분석한다.
