This study performed to identify the relationship between job stress and self-efficacy based on the related research review and text network analysis. For the literature review, we performed the search process at three domestic and one foreign database using key words, 'nurse', 'stress', 'self-efficacy'. A total of 18 papers were selected as the target literature. Nine of these studies reported a statistically significant negative correlation between nurses' job stress and self-efficacy. It was difficult to compare between studies' results because of the optional usage of the questionnaires. In addition, a text network analysis was conducted by extracting keywords from the 18 papers. The keyword with the highest frequency of appearance was job stress, and the main words with high frequency of emergence were self-efficacy, hospital, and correlation. To clarify the relationship between the keywords, it is proposed to perform a survey on the influence factors through the development of Korean version measurement.

The aim of this study is to provide basic data that can contribute to improving successful clinical adaptation and reducing turnover of new graduate nurses by analyzing research related to reality shock experienced by new graduate nurses using text network analysis. The topics of reality shock experienced by new graduate nurses were extracted from 115 papers published in domestic and foreign journals from January 2002 to December 2021. Articles were retrieved from 6 databases (Korean DB: DBpia, KISS, RISS /International DB: Web of science, Springer, Scopus). Keywords were extracted from the abstract and organized using semantic morphemes. Network analysis and topic modeling for subject knowledge structure analysis were performed using NetMiner 4.5.0 program. The core keywords included 'new graduate nurses', 'reality shock', 'transition', 'student nurse', 'experience', 'practice', 'work environment', 'role', 'care' and 'education'. In recent articles on reality shock experienced by new graduate nurses, three major topics were extracted by LDA (Latent Dirichlet Allocation) techniques: 'turnover', 'work environment', 'experience of transition'. Based on this research, the necessity of interventional research that can effectively reduce the reality shock experienced by new graduate nurses and successfully help clinical adaptation is suggested.

Recent research trend of North Korean mining and rock engineering in the past 10 years was analyzed by a literature review of mining and rock engineering papers published in North Korean major mining journals, 'mining engineering', 'geological and geographical science' and 'technology innovation' published in 2008-2017. Basic database was established by organizing bibliographic information and abstract data of research papers in each journal. For each journal, paper submission trend classified by research field was analyzed using the basic database. And further study was conducted to the papers which showed distinguishing methodology and result, to analyze the trend of North Korean mining and rock engineering. The literature study showed a recent trend of quantification and automation in mining and rock engineering researches in North Korea, which seems due to recent changes in North Korea's science and technology policy and deterioration of the mining conditions. The results of this study can be applied in the feasibility studies of North Korea's mineral resource development projects. Future inter-Korean technical cooperation and site survey on North Korean field can secure complement the reliability of this study.

The purpose of this research was to review the music choices of GIM therapists in GIM. Seven databases and nine music therapy journals were searched with keywords such as "Guided Imagery and Music", "GIM", "Helen Bonny", "Bonny method", "Music and Imagery" and "BMGIM" between 1964 to 2013. Every abstract was confirmed to see whether it meets this research topic. 12 of 126 articles that described the reasons for music choices were selected. It is the result of narrative literature review that GIM therapists chose music to match clients' qualities of moods, emotions, feelings related with issues and clients' themes in therapy. In 5 articles among the 12 articles, authors chose music with considering music elements analytically to match clients' states. Reasonable explanations for music choice were reviewed in these 5 articles. There were limitations to obtain common facts between articles because most of 126 articles were case studies which described from therapists's point of view in a qualitative way. A more fundamental research is required to obtain rationales of music choices in GIM as a music-centered music psychotherapy for the further research.

The purpose of this study was to identify the trends and risk of bias of research using time series analysis on health and welfare in Korea and to suggest a direction for future health and welfare research. The database searches identified 6,543 papers. Following the process for screening and selecting, a total of 91 papers were included in the systematic review. There has been a steady increase in the number of articles using time series analysis from 1987 to 2013. Time series analysis was applied in medicine and health science journals. The main goals were explanation and description. Most of the subjects were heath status and utilization of healthcare services. The main model used in the time series analysis was ARIMA followed by time series regression. The data were gathered from various sources, including the national statistical office and government agencies. For assessing risk of bias, some studies were found to have inadequate sample sizes or showed no time series graphs and plots. These findings suggest greater widespread utilization of time series analysis in the field of health and welfare and to use the appropriate analysis methods and statistical procedures to obtain more reliable results to improve the quality of research.

Purpose: Despite the decline in tuberculosis (TB) incidence and mortality rates in the Republic of Korea through a national TB control program, TB remains one of the most critical infectious diseases in Korean children. We investigated the trends and research areas of published articles on TB in Korean children and adolescents. Methods: In 6 Korean and overseas databases, we searched titles and abstracts including "tuberculo*" or "TB," "child*" or "adolescen*" or "neonat*" or "infant*" or "pediatric*," and "korea*." The publication type, publication year, research areas, journal title, and research subjects were analyzed. Results: Out of the 257 searched documents, 120 papers were included in the analysis. Of these, 82 were original articles (68.3%), 33 case reports (27.5%), 4 review articles (3.3%), and 1 guideline (0.8%). In the original articles, the most common subject of studies was the clinical characteristics of patients with TB (36.6%), followed by diagnostics (29.3%), contact investigations (9.8%), epidemiology (6.1%), treatment (4.9%), vaccine (3.6%), latent TB infection (3.6%), complications (3.6%), and surveys on perception of TB (2.4%). From 1962, 4 articles were published in the 1960s, 10 articles in the 1970s, 11 articles in the 1980s, 22 articles in the 1990s, 26 articles in the 2000s, and 47 articles since 2010. Conclusions: The amount of research on TB in Korean children has increased over the past 5 decades; however, it has mainly focused on the clinical characteristics and diagnostics. Research in different areas, such as treatment and vaccine, is needed in the future.
