We analyzed research trends of 288 Korean academic dissertations and articles regarding platform work, using topic modeling and keyword network analysis method. Research disciplines of many studies were laws, business administration, and economics fields. Thigh frequent themes were platform labor protection measures and direct or indirect effects of the sharing economy. The main keywords were digital, value, industry, and labor in terms of infrastructure and structural change. Besides, the main topics were the protection of platform workers, the values of sharing services, digital paradigm, and platform regulations. Based on the results of the analysis, we derived four implications and suggestions such as researching structural frames in macroscopic contexts, generalizing case analysis, and technology supplementation by applying average and quantitative analysis methods, researching individual competency development to realize the essential symbiotic value of sustainability, and developing customized vocational education and training programs.

In the context of open science, data sharing and reuse are becoming important researchers' activities. Among the discussions about data sharing and reuse, data journals and data papers shows visible results. Data journals are published in many academic fields, and the number of papers is increasing. Unlike the data itself, data papers contain activities that cite and receive citations, thus creating their own intellectual structures. This study analyzed 14 data journals indexed by Web of Science, 6,086 data papers and 84,908 cited references to examine the intellectual structure of data journals and data papers in academic community. Along with the author's details, the co-citation analysis and bibliographic coupling analysis were visualized in network to identify the detailed subject areas. The results of the analysis show that the frequent authors, affiliated institutions, and countries are different from that of traditional journal papers. These results can be interpreted as mainly because the authors who can easily produce data publish data papers. In both co-citation and bibliographic analysis, analytical tools, databases, and genome composition were the main subtopic areas. The co-citation analysis resulted in nine clusters, with specific subject areas being water quality and climate. The bibliographic analysis consisted of a total of 27 components, and detailed subject areas such as ocean and atmosphere were identified in addition to water quality and climate. Notably, the subject areas of the social sciences have also emerged.

정원(Garden)은 거주하는 주택과 외부공간의 전이공간 및 소통의 역할을 하고 있는 장소이며, 한국조경헌장에서 조경의 대상에 첫 번째로 거론되고 있는 중요한 조경계획의 대상이다. 조경학과 대학생들이 조경계획수업 시간에 처음 맞이하게 되는 주택정원설계에서 그들이 갖고 있는 정원에 대한 주제, 시설, 식재의 주요 사항들을 파악하고자 본 연구를 시작하였으며, 연구의 대상은 조경학과 대학생 2학년과정이며 시간적 범위는 2012년부터 2015년까지 4개년의 과제제출물을 대상으로 하였다. 대학생들의 정원설계작품을 살펴본 결과 첫째, 대학생들의 정원설계에서 사용되는 주요 주제는 가족과의 활동과 개인 취미생활, 자연에 관한 주제가 가장 많이 표현되었고, 이것은 정원안에서 개인과 가족과의 관계성을 고려하고 배려하는 곳이 정원이라는 인식을 갖고 있다고 보여진다. 둘째, 정원설계에서 조성되는 주요 시설은 휴양시설, 관리시설, 조경시설 순으로 배치되어 있으며, 일부 설계안에서는 교양시설과 유희시설이 조성되어 있었다. 셋째, 정원설계 작품의 식재경향은 교목위주의 식재가 많고, 관목과 지피와의 다층구조식재의 설계안은 몇 작품 보이지 않았으며, 독립식재와 군식 및 열식이 조화롭게 배치되지 못하고 있고, 지피류를 도입한 설계안이 많지 않았다. 오늘날의 정원설계는 다양한 디자인이 요구되고 있고, 근래 다수의 정원박람회에 출품되고 있는 정원작품 또한 디자인과 재료, 주제의 다양성이 풍부해지고 있다. 따라서, 대학생들의 정원설계과정에서 현재 학생들이 갖고 있는 주택정원에 대한 주요 요소에 대하여 다양성과 지속가능성을 높여줄 수 있는 효과적인 방향설정이 필요하다.

As information technology advances and changes in the library environment, a flexible view and reinventing perspective of LIS research is necessary. This study focused on the investigation of the recent(2000-2003) research trends by analyzing the contents of articles from the major academic research journals for getting a future oriented view of the field. A taxonomy developed by Hawkins(2003) was applied in order to find out the major pattern of research in the domestic as well as international LIS Journals, and Chi-Square Tests Analysis was used to figure out if the research pattern has any effect on research environment(vice versa).

The shock structure of dual coaxial jet is experimentally investigated. Eight different kinds of coaxial, dual nozzles are employed to observe the major features of the near field shock structure on the supersonic, coaxial, dual jets. Four convergent-divergent supersonic nozzles having the Mach number 2.0 and 3.0 are used to compare the coaxial jet flows discharging from two sonic nozzles. The primary pressure ratio is changed in the range between 1.0 and 10.0, and the assistant jet ratio from 1.0 to 4.0. The results show that the impinging angle, nozzle geometry and pressure ratio significantly affect the near field shock structure, Mach disk location and Mach disk diameter.

The focused crawler is a topic-driven document-collecting crawler that was suggested as a promising alternative of maintaining up-to-date web document Indices in search engines. A major problem inherent in previous focused crawlers is the liability of missing highly relevant documents that are linked from off-topic documents. This problem mainly originated from the lack of consideration of structural information in a document. Traditional weighting method such as TFIDF employed in document classification can lead to this problem. In order to improve the performance of focused crawlers, this paper proposes a scheme of locality-based document segmentation to determine the relevance of a document to a specific topic. We segment a document into a set of sub-documents using contextual features around the hyperlinks. This information is used to determine whether the crawler would fetch the documents that are linked from hyperlinks in an off-topic document.

This paper proposes a new enhancing document clustering method using a synonym of cluster topic and the similarity. The proposed method can well represent the inherent structure of document cluster set by means of selecting terms of cluster topic based on the semantic features by NMF. It can solve the problem of "bags of words" by using of expanding the terms of cluster topics which uses the synonyms of WordNet. Also, it can improve the quality of document clustering which uses the cosine similarity between the expanded cluster topic terms and document set to well cluster document with respect to the appropriation cluster. The experimental results demonstrate that the proposed method achieves better performance than other document clustering methods.

This study sought to develop an integrated information literacy curriculum that would have a strong relationship with curricula through the standard themes abstracted from theme network structures, scan and cluster analyses of the information literacy curricula. In addition, this study also attempted to develop a teaching-learning model for the developed integrated information literacy curriculum. This study utilized the themes of information literacy instruction that have interdisciplinary characteristics as analysis criteria in analyzing the commonality of information literacy instruction and the subject curricula. The following characteristics were found from the analyzing the areas of commonality. Foremost, the first themes(the fields of basic learning skills and nature) which belongs to the fields of information society, library, information technology, collaborative skills were found to have many relationships with the subject curricula. Next, the second themes(the field of information problem solving capabilities) which is the core field of information literacy instruction showed a weak relationship with the subject curricula.
