This study was to investigate and identify the trends and the direction of the researches related to the rooftop greening by analyzing the content of the studies published in Korea during the past two decades. Internet search was to collect data for this study, and the articles reviewed are limited to research journals, theses, and doctoral dissertations. The collected articles were then examined for content analysis and classified into several categories according to year, topic, and types of journals. The results showed that the total number of articles published in Korea for the period 1984-2004 was 97. While there was only one article in 1984, the number of articles has increased to 16 in 2000, 20 in 2003, and 16 in 2004 now. According to the analysis of the 97 data, there were 25 master's theses and 3 doctoral dissertations and 69 articles published in journals. Articles about rooftop greening were published most frequently in the Korea Institute of Landscape Architecture(11 articles), followed by Journal of Architectural Institute of Korea(8 articles) and Journal of Korea Society for Environment Restoration(7 articles).The studies regarding the rooftop greening has increased in number since the Ministry of Construction and Transportation made it possible to 10-15 cm shallow depth of soil in rooftop greening in 2000, which was above 100 cm before 2000. The articles examined are classified into four areas of research according to topic. The number of articles in each area is as follows : 57 articles in the field of the technology, 17 in the study of the plan and system, 10 in the case study, and 12 in the plant study, Particularly, the studies concerning technology are subdivided into the five areas and the number of each area is as follows : 25 studies for the plant base, 15 for design plan, 13 for the efficacy of the rooftop greening, 3 for the managing program, and 1 for the relation with buildings. Over the years, the studies for the rooftop greening have increased in number since these studies have made a positive effect on the improvement of the urban ecosystem and on the environment of the city lacking greens. However, the majority of research are for plant and planting base and those researches are not enough to make some effects on the improvement of the environment, it seems necessary to provide some system applicable to the field or to design practical study in order to contribute to the urban environment in Korea.

Objectives: The purpose of this study was to describe the trends of original research in the Korean Journal of Preventive Medicine, and to evaluate the quality of original articles about lead poisoning. Method: The data for the analysis of trends in preventive medicine research was taker from a total of 829 original articles published in the Korean Journal of Preventive Medicine from 1968 to 1997, The qualitative meta-analysis was measured against a checklist of evaluation criteria, which were divided into 10 categories, with 46 articles on lead poisoning. The evaluation process was performed independently by two evaluators, Results: The number of articles per 100 members over the study period increased by almost 4 pieces in the early 1980s, and by more than 9 pieces in the mid-1990s. In the major classifications of subjects, environmental and industrial health, epidemiology and health statistics, and health policy and management published 370 pieces (44.0%), 137 pisces (16.5%), 322 pieces (38.9%) respectively. In the order of the number of articles, five themes about health significance, including metal exposure (73 pieces), diseases associated with exposure to organic solvents (45 pieces), air pollution (36 pieces), maternal and child health (32 pieces), and occupational health (3D pieces) received consistent attention throughout the years $1968\sim1997$. The overall mean score of article qualify about lead poisoning was 37.8 out of 50. Of the articles any information on the purpose and hypothesis described well, Of those the originality of the subjects, the form of article's (including tables and figures), and the number of inappropriate words of abstracts showed very low score. For multiple regression analyses, the number of joint research institutes and the acceptance of research grants about the article quality were statistically significant. Conclusions: The number of original research reports in the Korean J Prev Med has recently increased and their subjects bave diversified. Of the basis of this study, the articles need improvement in the areas of abstracts, tables and illustrations (figures), etc. The Korean Society for Preventive Medicine will revise contribution regulations for manuscripts submitted to the Korean J Prev Med. Future studies should address these issues and perform the quantitative mata-analysis about the specific subjects including the quality of articles.

This paper aims to identify trends of domestic industry-academic cooperation through comparative analysis of domestic and overseas academic articles published over the past 10 years (2011-2021). To this end, keyword network analysis and topic modeling analysis were performed to identify the characteristics of the entire articles collected. As results, it turned out that domestic articles included school, employment, education, patent, and professor as a major keyword while for overseas articles, project, policy, innovation, and company were the main topics, and related keywords were found to be influential. These results suggest that domestic industry-academic cooperation would have been designed and led by universities focusing on education for employment, and need to be carried out more actively in the areas of 'research' and 'technology transfer with the government's related policies and support on establishing two-way relationships that can benefit both schools and participating companies.

Purpose: A significant amount of public opinion about nurse bullying is expressed on the internet. The purpose of this study was to analyze the linkage structures among words extracted from comments on internet articles related to nurse workplace bullying using semantic network analysis. Methods: From February 2018 to April 2019, comments made on news articles posted to the Daum and Naver web portal containing keywords such as "nurse", "Taeum", and "bullying" were collected using a web crawler written in Python. A morphological analysis performed with Open Korean Text in KoNLPy generated 54 major nodes. The frequencies, eigenvector centralities, and betweenness centralities of the 54 nodes were calculated and semantic networks were visualized using the UCINET and NetDraw programs. Convergence of iterated correlations (CONCOR) analysis was performed to identify structural equivalence. Results: This paper presents results about March 2018 and January 2019 because these months had highest number of articles. Of the 54 major nodes, "nurse", "hospital", "patient", and "physician" were the most frequent and had the highest eigenvector and betweenness centralities. The CONCOR analysis identified work environment, nurse, gender, and military clusters. Conclusion: This study structurally explored public opinion about nurse bullying through semantic network analysis. It is suggested that various studies on nursing phenomena will be conducted using social network analysis.

This study conducted a content analysis of the treatises published in JKHEA(Journal of the Korean Home Economics Association). In total, 2,136 articles published in JKHEA from 1995 to the first half of 2009 were reviewed. Articles were classified by subject matters, research methods, number of researchers, presence of research fund, language and number of reference. Although it is useful to employ content analysis in reviewing academic articles on human ecology in all journal publications, the sheer size of literature available makes this task nearly impossible. As such, we have chosen JKHEA as a popular representative journal on human ecology. This study presented the empirical results of research trends and other characteristics in JKHEA. As such, the results of this study presented a snapshot analysis of research on human ecology and future trends.
