This study was to review the research trends in domestic computing thinking and to suggest future research direction by analyzing 138 papers related to computing thinking published in domestic academic journals from 2015 to 2018. As a result, domestic research on computing thinking has been steadily increasing since 2015, and quantitative research, development research and experimental research were mainly used. Most research were conducted for elementary school students and university students. Research topics are oriented to the curriculum and program as well as the relationship among the variables related with computational thinking. It is necessary to explore empirical studies such as teaching methods, teaching tools, media utilization, and evaluation methods in order to promote learner's computing thinking. Also, it is needed to explore various variables related to enhance computing thinking and the relationship among the variables.

Medical education research subjects are incredibly diverse and have changed over time. This work in particular aims to compare and analyze research trends in medical education through the words used in the titles of these research papers. Academic Medicine (the journal of the Association of American Medical Colleges), Medical Teacher (the journal of the Association of Medical Education in Europe), the Korean Journal of Medical Education (KJME), and Korean Medical Education Review (KMER) were selected and analyzed for the purposes of this research. From 2009 to 2018, Academic Medicine and Medical Teacher published approximately 10 to 20 times more papers than the KJME and KMER. Frequently used words in these titles include "medical," "student," "education," and "learning." The words "clinical" and "learning" were used relatively often (7.80% to 13.66%) in Korean journals and Medical Teacher, but Academic Medicine used these phrases relatively less often (6.47% and 4.41%, respectively). Concern with such various topics as problem-based learning, team-based learning, program evaluations, burnout, e-learning, and digital indicates that Medical Teacher seems to primarily deal with teaching and learning methodologies, and Academic Medicine handles all aspects of medical education. The KJME and KMER did not cover all subjects, as they publish smaller papers. However, it is anticipated that research on new subjects, such as artificial intelligence in medical education, will occur in the near future.

This qualitative study aimed to investigate ways to improve effective cooperative learning from students' perspective by understanding and analyzing the learning experiences of nursing students who participated in a collaborative problem-solving learning model. Data were collected through focus group interviews and reflection journals of six second-year nursing students from G-university in J-city who participated in a collaborative problem-solving learning model course. The interview data were analyzed and divided into 3 categories and 10 subcategories according to the six-step thematic analysis method proposed by Braun and Clarke. The results of analyzing the interviews were considered based on three areas: preparation before learning, the process of collaborating as a cooperative learning experience, and solutions and expectations after learning. The participants felt frustrated because collaborative problem-solving took more time for individual learning than traditional methods did and would not allow them to check the correct answers immediately. However, they gained new experiences by solving problems and engaging in discussions within their learning community. The participants' expectations included material that could help their learning, measures to prevent free-riders, and consideration of the learning process in evaluation factors. Although this study has sample limitations by targeting nursing students in only one region, it can be used to help operate collaborative problem-solving classes, as it reflects the real experiences and opinions of students.

The purpose of this study is to report the research trends of Korean medicine treatment for alopecia areata. We investigated the studies on Korean medicine treatments for alopecia areata via searching 4 web databases of Korea. 13 papers were selected, and we classified them according to publication year, published journals, the types of study, research subject, the methods of treatment, confirmation of recurrence, methods of evaluation, and institutional review board(IRB). We analyzed a total of 13 clinical studies of Korean medicine on alopecia areata based on various criteria and reviewed the research trends. Based on this, we suggested points to be improved and supplemented when conducting clinical research on alopecia areata in the future. Clinical studies on alopecia areata started to be published in 2001, and acupuncture, pharmacopuncture, herbal medicines, etc. were used as treatment methods for alopecia areata. Most of the clinical studies on alopecia areata were case studies, so it is thought that various types of clinical studies are needed. In addition, it is necessary to confirm the recurrence of alopecia areata and to improve the awareness of research ethics.

Predictive maintenance has been considered fundamental in the industrial applications in the last few years. It contributes to improve reliability, availability, and maintainability of the systems and to avoid breakdowns. These breakdowns could potentially lead to system shutdowns and to decrease the production efficiency of the manufacturing plants. The present article aims to study how predictive maintenance could be planed into the production scheduling, through a systematic review of literature. . The review includes the research articles published in international journals indexed in the Scopus database. 165 research articles were included in the search using #predictive maintenance# AND #production scheduling#. Press articles, conference and non-English papers are not considered in this study. After careful evaluation of each study for its purpose and scope, 50 research articles are selected for this review by following the 2020 Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA) statement. A benchmarking of predictive maintenance methods was used to understand the parameters that contributed to improve the production scheduling. The results of the comparative analysis highlight that artificial intelligence is a promising tool to anticipate breakdowns. An additional impression of this study is that each equipment has its own parameters that have to be collected, monitored and analyzed.

Objectives. The purpose of this study was to evaluate the quality of abstracts of original articles. Methods. This subjects selected total 63 abstracts of the original articles of the Korean Journal of Preventive Medicine in 1997. The quality of abstracts was measured against a checklist of evaluation criteria, which were divided into eight categories and the numbers of inappropriate words (including grammar) according to criterionbased survey. A score for each abstract was obtained by dividing the number of criteria presented by the number applicable. The overall mean score was also determined. Results. The overall mean score of abstract quality was 0.55 out of 1. Of the abstracts subject selection 83% didn't include specific technical descriptors. Of those that gave conclusions 92% didn't address study limitations and 78% made no recommendations for future study. The overall mean number of inappropriate usage of words (including grammar) per abstract was 14.1. The overall mean number of English words was 283. In the multiple regression analyses, the research career of the first author and the number of English words to the number of inappropriate usage of words were statistically significant. Also, in the secondary regression model, the number of English words to the quality score of abstract was only statistically significant. Conclusions. Most of the abstracts provided some information pertaining to each evaluation criterion. However, they did not provide sufficient details to enhance the reader's understanding of the article. On the basis of the study the abstracts need improvement in its description of the reported subject selection, statements of limitations and recommendations, etc. The Korean Society for Preventive Medicine will recommend a proposal for more informative abstracts in Korean J Prey Med and will take into consideration the introduction of foreign review of abstracts. Future studies should address these issues and compare the quality of abstracts between different journals and their time of publication.

Demographic Analysis(DA) as well as Post Enumeration Survey(PES) are typical methods for evaluating completeness of census and vital statistics. In spite of its popularity, DA has never been attempted in Korea, while other international journals of demography have pointed out the backwardness of death registration in Korea in terms of DA approach. This paper introduces various DA methods and modifies them to be adequate for Korea census and vital statistics. Our method are also applied to reconstruct year-age-sex specific population and estimate their omission rates for year and age. Empirical analysis of census and vital statistics of Korea from 1985 to 2010 demonstrates high completeness of death registration in Korea, contrary to existing literatures. We also investigates abnormal patterns in census by comparing with reconstruction data in view of cohort, sex ratio and age ratio.
