목적: 본 연구는 사회적 고립 측정을 위한 평가에 대한 연구 동향을 계량서지학적 분석을 통해 파악하고자 한다. 연구방법: Web of Science 데이터베이스를 사용하여 문헌을 수집하였다. VOS viewer를 사용하여 국가/지역, 학술지, 연구기관, 저자, 키워드 및 클러스터 분석을 실시하였다. 결과: 문헌의 연도별 출판은 2011년 이후 급증하는 추세를 보였으며, 2020년에 가장 많은 문헌이 출판되었다. 공공환경 및 직업보건 분야에서 가장 많은 연구가 이루어졌으며, 미국과 영국이 높은 인용횟수와 연결강도를 보였다. 대한민국은 상위 20위로 나타났다. 주요 키워드는 코로나19, 건강, 외로움, 우울, 불안, 스트레스로 나타났다. 결론: 본 연구는 사회적 고립 평가에 대한 주요 키워드와 연구 동향 및 연결성을 파악함으로 시간적 흐름에 따른 연구변화를 파악하였다는 점에서 의의가 있다. 이를 바탕으로 사회적 고립의 예방적 관점에서 평가와 중재의 중요성을 파악하고 관련 연구의 기초자료로 활용되기를 기대한다.

For any research study, in order to achieve the researcher’s intended purpose, the depth of research is added, and the area of the subject is expanded by clearly defining the scope and objective. The study was undertaken to analyze the bibliographic data of 254 papers in the field of foodservice and restaurant published in the Journal of the Korean Society of Food Culture from 2002 to 2021. The study was divided into two periods: 2002 to 2011, and 2012 to 2021. Research topics were derived and research trends according to temporal changes were confirmed through analysis of keyword networks by period. In addition, analyzing the keyword network of simultaneous appearance of “foodservice” and “restaurant”, the research topics were compared and analyzed in relation to which keywords were expanded by period. Our analysis revealed that the research topics were mostly studied for satisfaction and nutrition. Additionally, they were classified into procurement, Korean food before employee menu, marketing, restaurant industry, and quality. In the period from 2002 to 2011, it was confirmed that studies encompassed a wide range of research topics, focusing on foodservice and restaurant; in the second period from 2012 to 2021, the research topics were more classified and subdivided.

Technology used by human beings has developed drastically over the years. Although people enjoy affluent lives as a result of this development, the depletion of resources has brought about a variety of environmental problems such as emission of fine dust, treatment of waste water, and global warming. Although studies on environmental pollution are being conducted continuously, there are a limited number of studies that analyze research trends from quantitative and qualitative perspectives. In order to examine the current research landscape, we employed Scopus to combine research interest in environmental science with bibliographic analysis. Among 74,089 papers published in 57 journals of environmental science, 3,212 papers were published by Korean authors and citations per publications and Field-Weighted Citation Impact (FWCI) of those papers were 7.3 and 1.0, respectively. By assessing the bibliometric indicators in the field of environmental science, this study provides insight into research trends and related data to aid researchers in developing research strategies.

The analysis of research trends is used to identify key subject areas, research trends over time, and new discussions in a study field. The purpose of this study is to examine the characteristics of research articles published in the area of rural planning using bibliometric methods. Research articles published in the Journal of Korean Society of Rural Planning 「Rural Plannin g」 from 1995 to 2014 were analyzed to determine the annual publications, the number of periodical contributions, the authorship patterns, and popular research subjects and keywords. The results of this study are as follows; (1) The number of research papers and authors has increased over the 20 years periods (1995-2014); (2) The most published authors are associated with the study of rural planning. Seoul National University, Rural Development Administration, and Chonnam National University have highly contributed to the paper publications; (3) The most frequent word in titles is “Rural“ for the whole period from 1995 to 2014. The most frequent words are “Village“ and “Planning“ from 1995-2006, and “Landscape“ and “Village“ in 2007-2010, and “Village“ and “Area“ from 2011-2014; and (4) The most used keywords are “Rural amenity“, “Rural village“, and “Rural landscape“ for all of the different time frames.
