  • 이 연구는 "한국사회복지학회"의 학회지에 1979년 창간호에서부터 2015년까지 게재된 논문들의 키워드를 분석함으로써 국내 사회복지학의 동향을 살펴보고자 한 연구이다. 전체시기에 대한 분석과 더불어 이를 두 시기로 나눈 분석을 병행함으로써 연구의 동향을 밝혀보게 된다. 연구의 가닥은 크게 셋으로 나뉜다. 첫째는 연구방법의 동향으로서, 질적, 양적 및 문헌연구의 비중이 시기별로 변화된 양상을 개관한다. 둘째는 연구주제의 동향으로서, 시기별 키워드 출현빈도의 추이를 분석한다. 셋째는 지적구조의 동향으로서, 키워드들의 중심성 지수의 변화를 살펴본 후에, 이들 사이의 관계를 분석해주는 패스파인더 알고리즘 및 네트워크 구조를 도식적으로 구현해주는 노드엑셀 프로그램 등을 활용하여 사회복지학 지적 구조의 흐름을 밝힌다. 끝으로, 이러한 분석결과들에 내포된 함의를 검토해 본다.

  • Image processing and computer vision technologies are becoming increasingly important in a variety of application fields that require techniques and tools for sophisticated image analysis. In particular, image segmentation is a technology that plays an important role in image analysis. In this study, in order to identify recent research trends on image segmentation techniques, we used the Web of Science(WoS) database to analyze the R&D topography based on the network structure of the author's keyword co-occurrence matrix. As a result, from 2015 to 2023, as a result of the analysis of the R&D map of research articles on image segmentation, R&D in this field is largely focused on four areas of research and development: (1) researches on collecting and preprocessing image data to build higher-performance image segmentation models, (2) the researches on image segmentation using statistics-based models or machine learning algorithms, (3) the researches on image segmentation for medical image analysis, and (4) deep learning-based image segmentation-related R&D. The scientometrics-based analysis performed in this study can not only map the trajectory of R&D related to image segmentation, but can also serve as a marker for future exploration in this dynamic field.

  • This study examines the trend of research on food and culture in papers published in the Journal of The Korean Society of Food Culture from 1986 to 2020. The journals published a total of 329 papers, which we classified into 5 main categories and 13 middle categories. Of these, 204 articles were on "Korean traditional food culture." The most studied topic in the entire period was "Perception of Koreans towards traditional food, preference, satisfaction, and usage." A total of 76 studies related to "Korean contemporary food culture." The most advanced topic researched concerned "Recognition and attitude"; these studies were consistently carried out throughout the research period. The main classification of "World food culture" encompassed 32 studies, with major research focused on "World's Modern Food Culture" and the most advanced being "Comparison of Food Cultures of Foreign and Korean Food Cultures." All studies were consistently spaced out during the study period. These studies provide an integrated knowledge in the field of food and culture and can be used as a basic material for related research in the future.

  • 1) Purpose : The purpose of this research is to identify the trend of job stress of hospital nurses based on last 10 years of domestic research and to suggest directions for systematic future research. 2) Methodology : 101 studies between 2006 and 2016 were selected using key words such as registered nurse and job stress from Academic Information Service(Riss4u), the National Assembly Library and Korean studies Information Service System(KISS). 3) Findings : The researches on job stress of hospital nurses were increasing. The result showed that job stress increased for shift nurses. Especially, nurses of small-medium sized hospital showed remarkable effects to organization such as turnover intention. In addition, although the importance of approach to management is emphasized, there is little research on these aspects. 4) Practical Implications : It is necessary to develop systematic research on job stress directly effecting turnover intention of hospital nurses from hospital management aspect. The development of job stress measuring tools reflecting the characteristics of the medical institution, and the human resources management plan to resolve the imbalance in manpower for nurses should be required.

  • Objective : In this article, we overviewed clinical Korean Medicine studies on dementia by analyzing papers published in Korea from 2010 to 2019. Methods : We explored research articles on dementia from 5 Korean research databases using the keyword 'dementia' and 'Korean Medicine'. We included original articles and reviews of clinical Korean Medicine and excluded single case study and experiment article of animal model. Then we analyzed them according to the published year, journal type, and research topics. Results & Conclusions : Research topics were classified into 'research trend', 'treatment', 'prevention', 'evaluation', 'medical expenses', 'collaborative practice' and 'others'. The largest number of articles were published in 2011(24.4%). 'Journal of Oriental Neuropsychiatry' was the journal with the most published articles(46.3%). In research topics, the analyses of research trend accounted for the largest portion(39.0%) and the articles about treatment for dementia or evaluation index in Korean medicine had the second largest proportion(14.6%). We hope that various researches for therapeutic effects, mechanisms and preventive effects of Korean Medicine in dementia would be conducted for future study.

  • Recently, a high speed spindle is an essential part of machine tools to satisfy latest demand of high precision product and machining of hard materials. But, there are many disadvantages such as heat generation of built-in-motor, bearing friction, noise, vibration and displacement because of the high speed. Many researches on spindle systems have been conducted for solving these problems. In this study, technical trend of machine tools spindle systems are analyzed with patent PSM, mapping and grouping. The analysis is carried out for the applied patent during January 2000 and December 2009 in Korea, Japan, EU and U.S.A. And development of the direction, strategy and promising technologies of the spindle system are suggested.

  • Research and application of three dimensional packaging technology in electronics have been increasing according to the trend of high density, high capacity and light weight in electronics. In this paper, TSV fabrication and research trend in three dimensional packaging are reported. Low alpha solder bumping which can solve the soft error problem in electronics is also introduced. In detail, this paper includes fabrication of TSV, functional layers deposition, Cu filling in TSV by electroplating using PPR (periodic pulse reverse) and 3 step PPR processes, and low alpha solder bumping on TSV by solder ball. TSV and low alpha solder bumping technologies need more studies and improvements, and the drawbacks of three dimensional packaging can be solved gradually through continuous attentions and researches.
