  • This study is to evaluate the drought-related bigdata characteristics published from South Korean by developing crawler. The 5 years (2013 ~ 2017) drought-related posted articles were collected from Korean internet search engine 'NAVER' which contains 13 main and 81 local daily newspapers. During the 5 years period, total 40,219 news articles including 'drought' word were found using crawler. To filter the homonyms liken drought to soccer goal drought in sports, money drought economics, and policy drought in politics often used in South Korea, the quality control was processed and 47.8 % articles were filtered. After, the 20,999 (52.2 %) drought news articles of this study were classified into four categories of water deficit (WD), water security and support (WSS), economic damage and impact (EDI), and environmental and sanitation impact (ESI) with 27, 15, 13, and 18 drought-related keywords in each category. The WD, WSS, EDI, and ESI occupied 41.4 %, 34.5 %, 14.8 %, and 9.3 % respectively. The drought articles were mostly posted in June 2015 and June 2017 with 22.7 % (15,097) and 15.9 % (10,619) respectively. The drought news articles were spatiotemporally compared with SPI (Standardized Precipitation Index) and RDI (Reservoir Drought Index) were calculated. They were classified into administration boundaries of 8 main cities and 9 provinces in South Korea because the drought response works based on local government unit. The space-time clustering between news articles (WD, WSS, EDI, and ESI) and indices (SPI and RDI) were tried how much they have correlation each other. The spatiotemporal clusters detection was applied using SaTScan software (Kulldorff, 2015). The retrospective and prospective cluster analyses were conducted for past and present time to understand how much they are intensive in clusters. The news articles of WD, WSS and EDI had strong clusters in provinces, and ESI in cities.

  • Purpose: This study was attempted to see the trends in breast cancer researches in Korea. Method: We collected a total of 94 articles associated with breast cancer and published in Korea from 1976 to August 2004 and analyzed the characteristics of those articles, the journals which published those articles in each year, the research designs, subjects, intervention effects in experimental studies, the subjects and concept distribution in comparative researches and themes of the articles. Result: 1. Articles published and associated with breast cancer have increased since 1990 and picked after 2000. 2. Most research designs are survey and correlation studies which are non-experimental research(70.2%) and next are experimental and qualitative researches. 3. In a total 17 articles which are experimental researches, intervention studies which use exercise programs are most(5 articles) and the next are education program, supportive nursing intervention, guided imagery, massage and rehabilitation programs. 4. In correlational researches, concepts such like social-psychological adaptation, partner support, health promotion behavior and family support are treated frequently. 5. Subjects in most comparative studies are patients with breast cancer and normal women. 6. Most nursing research themes are psycho/spiritual problems, 16 articles(17.0%). Conclusion: These results show that the researches related with breast cancer have actively increased and body functions and psycho-social variables have been improved through nursing intervention. Therefore, it seems that more systematic interdisciplinary studies and systematic complement are necessary for future breast cancer nursing researches.

  • Objectives: The aim of this study was to understand the characteristics of herbal-drug-associated adverse events (AEs) reported in the internet newspaper articles and to take a countermeasure against the safety issue of herbal drugs. Methods: We searched the internet newspaper articles published from 2010 to 2014 in the 3 major portal sites in Korea, NAVER, DAUM, and GOOGLE. Search terms were the Korean words equivalent of 'herbal drug' and 'side effects'. Informations on the type and characteristics of suspected herbal drugs, AEs, and the patient records were extracted from the articles reporting the herbal-drug-associated AE occurred in Korea. Results: From 8,806 articles, a total of 36 AEs were found. The most frequently reported age group was 20s, and women outnumbered men. Obesity was the most common cause of administration. Doctors of Korean medicine clinic were the most commonly referred prescribers and purchasing route (11 cases). The most frequently mentioned medicinal herb was Ephedra sinica (7 cases) and the most commonly reported AEs were abdominal pain (8 cases), dizziness (6 cases), diarrhea (5 cases), and vomiting (5 cases) were followed in order. Ten cases were judged as serious AEs, and the others were not. Conclusions: Current customers demand health care providers to offer them sufficient information on the safety of herbal drugs. To satisfy their requirements, physicians of Korean medicine should be able to explain, predict, prepare, recognize, and deal with the herbal-drug-associated AEs. We propose an establishment of pharmacovigilance system for herbal medicine, in which doctors of Korean medicine are participated as important personnel, to collect and analyze the related AEs and offer credible information on the safety of herbal drug.

  • A trend analysis of research articles in a field of knowledge is significant because it can help in finding out the structural characteristics of the field and the future direction of research through observing change in a time series. We identified the structural characteristics and trends in text data (keywords) gathered from research articles which in itself is an important task in various research areas. The titles and keywords were crawled from research articles published from 2016 to 2018 in the Research Journal of the Costume Culture (RJCC), one of the representative Korean journal in the field of clothing and textile. After we extracted data comprising English titles and keywords from 195 published articles, we transformed it into a 1-mode matrix. We used measures from network analysis (i.e., link, strength, and degree centrality) for evaluating meaningful patterns and trends in the research on clothing and textile. NodeXL was used for visualizing the semantic network. This study observed change in the clothing and textile research trend. In addition to covering the core areas of the field, the subjects of research have been diversifying with every passing year and have evolved onto a developmental direction. The most studied area in articles published by the RJCC was fashion retailing/consumer psychology while aesthetic/historic and fashion industry/policy studies were covered to a more limited extent. We observed that most of the studies reflecting the identity of RJCC share subject keywords to a significant extent.

  • The purpose of this paper is to understand the profiles of users and their motivations in sharing research articles on Twitter. The goal is to contribute to the understanding of Twitter as a new altmetric measure for assessing impact of research articles. In this paper, we extended the previous study of tweet motivations by finding out the profiles of twitter users. In particular, we examined six characteristics of users: gender, geographic distribution, academic, non-academic, individual, and organization. Out of several, we would like to highlight here three key findings. First, a great majority of users (86%) were from North America and Europe indicating the possibility that, if in general, tweets for research articles are mainly in English, Twitter as an alternative metric has a Western bias. Second, several previous altmetrics studies suggested that tweets, and altmetrics in general, do not indicate scholarly impact due to their low correlation with citation counts. This study provides further details in this aspect by revealing that most tweets (77%) were by individual users, 67% of whom were nonacademic. Therefore, tweets mostly reflect impact of research articles on the general public, rather than on academia. Finally, analysis from profiles and motivations showed that the majority of tweets (from 42% to 57%) in all user types highlighted the summary or findings of the article indicating that tweets are a new way of communicating research findings.

  • 최근 문서 저작권에 대한 관심과 중요도가 높아지고 있어 문서 표절에 관한 연구가 지속적으로 이루어지고 있다. 이러한 표절 문제는 신문기사의 경우에서도 큰 관심을 끌고 있는데, 이는 상업적 가치가 큰 기사의 표절 또는 무단도용 문제가 적지 않게 발생하고 있기 때문이다. 현재까지의 문서 표절 관련 연구는 실시간 특성이 매우 강한 신문 기사의 표절 문제에 적용하기 어려웠다. 따라서 현재는 이러한 표절 기사를 가려내기 위해 수백 개의 신문사에서 하루 수천 건씩 올라오는 기사들을 눈으로 일일이 가려내는 상황이다. 본 논문에서는 이러한 시간과 비용의 문제를 줄이기 위해 네이버와 다음에서 제공하는 웹 검색 OpenAPI를 활용해 표절 가능성이 있는 기사들을 1차적으로 선별한 다음, 선별된 기사들과 원본 기사와의 문서 유사도를 측정하여 선별된 기사들의 표절 여부를 자동으로 판정할 수 있도록 하였다. 본 연구에서는 실험을 위하여 연합뉴스에서 제공되는 기사를 원본 기사로 활용하였고, 표절 가능성이 있는 기사는 네이버 및 다음의 뉴스 서비스에서 제공되는 모든 기사 중에서 선별하도록 하였다.

  • Objectives: This study aimed to analyze research trends in autism spectrum disorder (ASD) and savant syndrome and their cognitive characteristics through a systematic literature review. The objectives of this study were to establish an overview of research trends in ASD and savant syndrome, analyze the overall characteristics of individuals with ASD and savant syndrome, and examine their cognitive characteristics. Methods: For the systematic literature review, three criteria were used to select review articles: 1) literature from peer-reviewed journals, published in the past 15 years, from 2008 to 2022; 2) subjects with ASD and savant syndrome; 3) study objectives focused on the basic phenomenon and cognitive characteristics of ASD and savant syndrome. Finally, based on the selection criteria, a total of 40 articles were included. Results: Five themes and nine subthemes were derived from the analysis of 40 studies. The five main themes were as follows: 1) What is savant syndrome? 2) Demographic characteristics of savant syndrome; 3) Spectra of savant syndrome; 4) Savant syndrome and ASD; and 5) Cognitive characteristics of ASD with savant syndrome. The subthemes of the cognitive characteristics were weak central coherence, detail-focused cognitive processing, enhanced perceptual functioning, and hyper-systemizing. Conclusion: Several studies have been conducted to understand ASD and savant syndrome; however, no single theory can specify the cognitive characteristics of people with ASD and savant syndrome. Therefore, further systematic and multi-layered research on ASD and savant syndrome are required for more comprehensive results.

  • This historical research was conducted to analyze and categorize the titles which were presented in the journal, The Korean Nurse, from August 1962 to October 1995. Titles which were published with the purpose of educating graduate nurses and to update 0 their nursing knowledge to improve professional practice were included. There were 348 articles published from the beginning of publication in August, 1962 to October, 1995. All of the journals were reviewed except nine missing journals which were not available in any library. According to the characteristics of the articles in the periodical, the articles were divided into three periods. In each of the three peroids there were five categories: Subject, Clinical Practice, Fundamentals of Nursing Science, Nursing Administration, Others. These categories were adopted from Kim's(1994) division system which was developed to analyze nurse's insurance education program. The special feature peroid was from August, 1962 to December, 1974. In this period the articles were presented in an unorganized manner in the area of special feature or main issue. The largest area was the subject category(44%). The second largest area wes the fundamental of nursing science category(31%). From May, 1975 to December, 1977, the articles with the educational purposes were published in a designated area called continuing education. This period was labelled as the continuing education period. Among the published articles in this period, 45% focused on the subject category and 45% on the fundamentals of nursing science category. In this period the articles were focusing on nurses 'work in specific areas such as industry, nurses' aid schools, and nursing administration, articles on physical assessment first started to appear. The written continuing education period was from January 1978 to October, 1995. All the educational articles published in this area were analyzed and categorized into five areas as for the other periods. 48% of the articles focused on the subject category. In the mid-eighties, the term nurse specialist first.appeared and ten years later in 1990, the titles were subdivided into more specific titles, such as, home nursing, industrial nursing, emergency nursing, 23% were in the fundamental nursing science category and they dealt with nursing process, nursing theories, theory development. For the content analysis, three articles, one from each period, dealing with cardiovscular diseases were selected for comparsion. First, the special feature period, the title of the article was on diet therapy for cardiovascular disease patients, but instead the content was about rest, hygiene, medication, observation. They recommended rings to prevent bed sores, which is now considered as a cause for bed sores. In the continuing education period, the content was more focused on rehabilitation rather than general nursing .care. It became more specific, systematic, and organized compared with the special feature period. In the written continuing education period, the focus was on rehabilitation, not broadly, but very specifically on exercise. The further research on the content analysis is recommended along with a comparison of the trends in the Journal of Nurses Academic Society.
