  • This study aims to examine research trends on the Internet of Things and smart city based on papers from the United States, Japan, and Korea. We collected 7113 papers related to the Internet of Things and smart city published from 2016 to 2021 in Elsevier's Scopus. Keyword frequency and centrality analysis were performed based on the abstracts of the collected papers. We found keywords with high frequency of appearance by calculating keyword frequency and identified central research keywords through the centrality analysis by country. As a result of the analysis, research on security, machine learning, and edge computing related to the Internet of Things and smart city were the most central and highly mediating research conducted in each country. As an implication, studies related to deep learning, cybersecurity, and edge computing in Korea have lower degree centrality and betweenness centrality compared to the United States and Japan. To solve the problem it is necessary to combine these studies with various fields. The future research direction is to analyze research trends on the Internet of Things and smart city in various regions such as Europe and China.

  • Objectives: The aim of this study is to analyze cancer research trends in traditional Korean medical journals indexed in the Korea Citation Index since 2000. Methods: Cancer research papers published in traditional Korean medical journals were searched in databases from inception to October 2022. The numbers of publications by journal and by year were descriptively assessed. After natural language processing, topic modeling (based on Latent Dirichlet allocation) and keyword network analysis were conducted. Results: This research trend analysis involved 1,265 papers. Six topics were identified by topic modeling: case reports on symptom management, literature reviews, experiments on apoptosis, herbal extract treatments of breast carcinoma cell lines, anti-proliferative effects of herbal extracts, and anti-tumor effects. Keyword network analysis found that the effects of herbal medicine were assessed in clinical and experimental studies, while acupuncture was mainly mentioned in clinical reports. Conclusions: Cancer research papers in traditional Korean medical journals have contributed to evidence-based medicine. Further experimental studies are needed to elucidate the effects of on different hallmarks of cancer. Rigorous clinical studies are needed to support clinical guidelines.

  • Agile software development methodology has been implemented by software industries over a decade ago and well accepted in the practitioner community. However, there is limited understanding on how agile practitioners aware towards implementation of agile practices in software development. Lack of awareness will lead to misunderstandings among agile practitioners and misuse the agile practices. In order to understand the awareness of agile practices, this paper aims to investigate the factors that affect awareness of agile practitioners in implementing agile practices. A systematic literature review (SLR)was conducted in order to classify and define the factors of awareness in agile software development methodology. The review was based on papers between 2002 and December 2014 from seven electronic databases. The relevant papers were included 20 journal articles, 24 conference papers,16 book chapters, 9 workshop papers. Consequently, 69 papers were identified that closely related with awareness in agile software development methodology. From the thematic analysis, 13 factors were classified from 42 elements. Based on the review result, understanding the influential factors on the awareness of agile practices will provide benefit to researchers and agile practitioners.

  • Objectives: The purpose of this article is not until to investigate the changes and types of statistical methods and to point out the statistical errors after analyzing the method of articles that improve the quality of the statistical analysis of papers published in the Journal of Oriental Obstetrics and Gynecology. Methods: Papers published in the Journal of Oriental Obstetrics and Gynecology from 2009 to 2011 were reviewed for methodological and statistical validity using a modified version of Ahn's checklist. A statistician reviewed individual papers and evaluated the list items in the checklist for each paper. To avoid the potential assessment error by the statistician who lacks expertise in the field of Oriental Obstetrics and Gynecology. Results: A total of 190 papers including 64 original articles, 40 reviews article, 58 case report and 28 brief communication were reviewed. Statistics methods used in 121 papers were composed of t-test(58.7%), ANOVA test(19.8%) and ${\chi}^2$- test (14.0%) et al. Whereas only 14.9% of papers were free of statistical errors, the number of omission errors was 58 and the number of commission errors was 149 each. Conclusions: A variety of statistical errors were encountered in papers published in the Journal of Oriental Obstetrics and Gynecology. Accordingly, researchers should be more careful when it comes to describing and applying statistical methods.

  • Purpose: This study was to examine the frequency, distribution and characteristics of researches using biological measurement published from 2000 to 2004 in 10 major nursing journals in Korea, Design: Literature analysis. Method: Journals including papers using biological measurements, publishing year, research design and outcome variables were analyzed. Results: 1. Researches using biological measurement were 318(13.3%). 2. Researches using biological measurement in the Korean Academy of Nursing were highest(97papers, 17.5%) among the nursing journals. The proportion of papers using biological measurement to total number of papers was the highest in the Journal of Korean Biological Nursing Science as 77.3%(51papers). 3. The 233 papers(73.3%) were experimental researches among 318 papers using biological measurement which showed the highest proportion. 4. Patients were highest subjects of researches using biological measurement(197papers, 61.9%). 5. Blood test was most frequently used as physiological variables from 2001 to 2004. Conclusion: Researches using biological measurement of 10 Korean Nursing Journals in year 2000-year 2004 were very low. We need more researches using biological measurement to provide more objective evidence for nursing practice.

  • Rheumatoid arthritis refers to acute and chronic arthritis due to unexplained autoantibody attack. Rheumatoid arthritis should be accompanied by difficulty in mobility and severe distress due to the progression of systemic arthritis. Therefore, this study early diagnoses the effects of Rheumatoid factor (RF), C-reactive protein (CRP), and Anti-cyclic citrullinated peptide (Anti-CCP), which are typical serum markers for rheumatoid arthritis by meta-analysis. Pubmed and EMBASE, were used as PICO criteria, and two independent researchers selected papers according to the criteria set in this study. The selection criteria was a study of patients with rheumatoid arthritis who developed early onset, and the paper was evaluated using the NCS. Forest plot and Funnel plot graphs for each serum marker were calculated using Revman 5.4. After finding 193 papers on Pubmed and 184 papers on EMBASE and selecting according to the criteria, a total of 41 papers were used for the analysis. The magnitude of the effect that appears in the Forest plot of RF with the Mean differnce value is 134.34, CRP is 21.42 and Anti-CCP is 270.41. The magnitude of the effect of Anti-CCP in meta-analysis was analyzed to be larger than that of RF and CRP, and it is considered that the development of early-diagnosis serum markers using Anti-CCP and additional retrospective studies are highly effective. The combination of RF, CRP, and Anti-CCP as a panel marker is expected to be very efficient.
