Objectives : The purpose of this study was to assess the statistical methods errors used in the journal of Oriental Rehabilitation Medicine(JORM) and to identify the types of errors in statistical analysis. Methods : We reviewed quantitative articles that were published in the JORM from January 2005 through October 2009. Those were not used by statistical analysis such as literature studies, case study, review articles were not included in this analysis. A total of 296 articles was reviewed. We evaluated the adequacy and the validity of the statistical techniques with our checklist established be modified Lee's checklist, and three statistical evaluators assessed together to minimize bias. Results : Of the 222 articles, 213 were used in inferential and descriptive statistics. Of those 80% of articles adopting descriptive and inferential statistics were detected having statistical errors. One articles used 1.7 statistical method unit generally. Most frequently employed statistics were student t-test, one way ANOVA. pearson correlation analysis, Mann-whitney U test, paired t-test, and chi-square test in their order. However, most frequent statistics having errors were similar in order. The most common statistic errors were as follow: 1. absence of normality test, 2. misuse between paired test and unpaired test, 3. wrong choice of repeated measures analysis without consideration of time variables, 4, increase of Type I error by using inappropriate multiple test, 5. inappropriate application of discrete or categorical data instead of continuous data in correlation analysis, 6. poor consideration of basic consumption in chi-square test, 7. confusion between frequency comparison and average comparison, 8. mentioning the statistical technique without using it. Conclusions : We found various mistake or misuses in the applications of statistical methodologies in the articles published in the JORM. Careful consideration of statistical use and review from the specialist of statistics are warranted for improving the quality of JORM.

Purpose: This descriptive study was performed to explore trends in child health nursing research by analyzing the themes, contents and structure of articles published in 2014 in Child Health Nursing Research, the official journal of the Korean Academy of Child Health Nursing. Methods: Thirty-eight articles were reviewed using keywords, author (s), subjects, ethical considerations, designs, statistics involved, funding resources, and others. Results: Ten domains from 160 keywords were identified as follows, child related, psycho-social variable related, parents and family related, nursing and health related, and others. A mean of 2.9 authors per article was identified and 71% of the authors were academic- affiliated. Twenty-eight articles were human-participant related while 21 articles addressed both Institutional Review Board and written consent. Non-experimental design was the most commonly used method followed by experimental design, and qualitative design. The duration for acceptance was a mean of 89.1 days from submission with most articles requiring a second round of article review. Half of the articles were supported by grant organizations such as Korean National Research Foundation. Conclusion: The findings of the analysis show an improvement in the scientific quality with a diversity of articles in Child Health Nursing Research.

The purpose of this paper is to analyze media companies' editorial viewpoints regarding environmental issues. Not only do newspaper editorials provide a variety of environmental information, but also they make it possible for the public to form an opinion and to establish communication channels regarding environmental issues. With this in mind, this paper analyzes the changes in environmental reporting over the past two decades. The newspaper companies started writing more frequently about the environment from early 1980s. To show this, I analyzed environmental articles written in the six main news-paper companies: Chosun, Donga, Hangerae, Kyunghyang, Hankook, and Munwha from 1999 to 2004. For this study, the articles have been complied by using the Korean Integrated News Database System (KINDS). Also the data has been sorted according to year, subject, and ty the company of origin. The total number of the environmental articles posted on these six daily newspapers from 1999 to 2004 is 729 and these represent 2.59% of the total articles. Hankook-Ilbo was the company that handled the most of environmental articles followed by Hangerae, Munwha, Kyunghwang, Chosun, and Donga. The major topics of discussion were environmental development and water quality issues. The number of the environmental related articles increased in 1999 and 2000, but then decreased from 2001 to 2003. Again the number increased in 2004. Interestingly while the number of articles covering the environment increased from the 1980s and into the 1990s, the number of articles decreased from 1999 to 2004 as the post-IMF period seems to have suppressed interest in the ecological issues despite the economic growth that followed. With the change in media coverage people have begun to recognize environmental issues as having social impact. As a result the people have begun to take such issues more seriously and take more active role in effecting environmental policy. Thus it is important that the media presents it's stories in an object manner to insure that the public is properly informed.

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.

Objectives : The purpose of this study is to establish the basis of the assessment tools that can be used for the diagnosis and assessment of skin diseases by reviewing the present status of the assessment tools used in domestic and overseas traditional medicine papers for the past five years. Methods : This study is based on analysis of papers on clinical trials about atopic dermatitis, psoriasis, acne, urticaria published from 1st July 2013 to 30th June 2018. The papers were searched from Oriental Medicine Advanced Searching Integrated System(OASIS), Korean Traditional Knowledge Portal(KTKP), Pubmed, MEDLINE. Results : 40 articles on atopic dermatitis, 34 articles on psoriasis, 26 articles on acne and 10 articles on urticaria were selected. Among them, 38 articles(90%), 20 articles(85%), 22 articles(85%) and 5 articles(50%) used assessment tools in order. Conclusions : SCoring Atopic Dermatitis(SCORAD), objective SCORing of Atopic Dermatitis index(OSI), Eczema Area and Severity Index(EASI) were used in studies on atopic dermatitis. In the case of psoriasis, The Psoriasis Area and Severity Index(PASI) was used in most papers. In the study on acne, most of Korean papers used Korean Acne Grading System(KAGS), but in the overseas papers, various assessment tools were used. In the case of urticaria, the rate of use of the assessment tool was the lowest, but the assessment tool used was unified by Urticaria Activity Score(UAS). Since skin diseases can cause stress and a decrease in quality of life, the quality of life should be taken into account when evaluating treatment effects.

Background: There haven't been any papers that have analyzed the recent trends in the changing attitudes and results of Korean thoracic and cardiovascular surgeons who submit scientific papers to the major cardiothoracic journals. Material and Method: I analyzed the original articles that were published in the major cardiothoracic surgery journals from 1995 to 2008 by Korean thoracic and cardiovascular surgeons. The data was retrieved from the internet websites of Pubmed, three major international SCI (Science Citation Index) journals and the Korean Journal of Thoracic and Cardiovascular Surgery. I then analyzed the data according to the chronological year, the subjects and the subspecialties. Result: The total number of original articles in the three international journals was 14,629. Among them, the number of articles written by Korean scientists was 157 (1.07%). A sharp increase was identified from 28 articles out of 7,674 articles (0.36%) prior to 2002, to 129 articles out of 6,955 articles (1.83%) after 2003. On the other hand, the annual number of articles in the Korean Journal was markedly decreased from 126.8 articles by 1999 to 80.0 articles after 2000. The annual number of articles in the Korean Journal was also decreased from 58.8% by 1999 to 48.3% after 2000. Conclusion: There was an observed increase in submitting articles to the international SCI journals after 2000 rather than to the Korean journal. The proportion of original articles in the Korean journal is also decreasing. I think we need to pay special attention to improve the quality and quantity of articles published in the Korean journal.

With the recent increase of sensitivity to decors, there has been an ever-increasing significance of exhibiting the beauty of the outer looks of an article. This trend has necessarily led to the diversification and also specialization of the color scheme activities. And so, it is inevitable that we should form the substantial ideas of the color scheme and further on, enhance the efficacy of its orientation under the prevailing circumstances. Now, we come to a realization that we must first take a glance at the whole picture of the arrays of color embedded in a variety of articles in the sixties and seventies of the 20th century, a bold introduction of color designs, thereby tracing the birth of color designs and finding a meaning in its mechanism. This study begins with the obtaining of a large collection of articles in those days, along with the literature on the commercial effects color suggest, and looking into the background of their trend and finding a meaning that underlies what these colors suggest. The general idea of those color designs exemplifies that the color selection was none other than the simplicity and convenience in the making of things in doser relation to the easy selling. With the advance of material quality and enhancement of the industrial idealism, it has been proved that color plays an important role in depicting the image of quality and tastes of class. In that role color has been given the indicator of visual delights and differentials in quality articles. All this has been reflected in a diversity of articles: for instance, white for household appliances, prime color for living necessaries and natural color for the decore like furniture. Formerly, after all, people used to have little regard for color. What is color for, it was thought, in relation to the selling image of articles? That is wily our preceding generation pays attention only to the first-hand looks of articles, neglecting the intensive study on color. We are beginning to understand what image a certain color scheme evokes in our feeling.

Objectives : The purpose of this study is to review the recent research trends of evidence based medicine, especially human randomized controlled trials on acupuncture. Methods : The articles were collected by retrieving the database of Pubmed and Journal of Korean Acupuncture & Moxibustion Society. The retrieving period was from October 2003 to September 2008, and the search term was 'acupuncture'. The articles were classified according to their publication journals, countries, publication years, targeted diseases, types of acupuncture and types of control. Results : In total, 558 articles in Pubmed and 35 articles in Journal of Korean Acupuncture & Moxibustion Society were searched. The number of articles on acupuncture research has increased with higher rate since 2000, but the Qualitative development has not achieved the same amplitude. Studies in Korea were insufficient both in Qualitative and Quantitative aspects. In countries, China had the most papers, and in targeted diseases, pain diseases were most dominant. In the types of acupuncture, classical acupuncture, and in the types of control, conventional western treatment showed the highest frequency. Conclusions: We need to do many-sided and more high Quality researches on acupuncture. For that, well-designed randornized trials are absolutely necessary.

The purpose of this study is to analyze quantitatively the use of statistics, especially inferential statistics, in library and information science. Thus this study compared the use of statistics in library and information science with it in social work and education. The results of this study are as follows: First, the result is that, when the proportions of articles in each of the three categories of use are compared, library and information science is deficient in the use of inferential statistics and unusually productive of articles in 'No Statistics' category and 'Descriptive Statistics Only' category. Second, ANOVA showed no significant difference in the means for number of articles with no statistics and for articles with descriptive statistics only, but did show a statistically significant difference for the means for number of articles with inferential statistics. That is, the use of inferential statistics in library and information science was very less than the other subject areas. Third, a comparison of the numbers of various inferential statistics for each of the three subject areas indicated that the differences were not significant. This fact means that the quality of inferential statistics used in library and information science was similar to the other subjects.

Objectives: This purpose of this study was to examine the trends in interventional research and analyze the contents and results of intervention through a systematic literature review of the domestic research literature, suggesting the effect of an oral care program on elementary school students. Methods: A total of 262 articles were retrieved initially, and the duplicate articles were then removed, excluded after screening titles, abstracts, and full-text articles. Finally, a total of 16 papers were used in the review. Results: The study included 9 articles with the nonequivalent control group pretest-posttest design and 7 with the one-group pretest-posttest design. All articles were of non-randomized studies. The most common index of the interventional effect was dental plaque. Further, oral health behaviors and knowledge, perception, self-efficacy, and DMFT index were common indices. In the quality assessment, in the "blinding of outcome assessment" among six items of ROBANS, 12 studies showed a high risk of bias. Conclusions: In order to develop an interventional oral health care program for elementary school students and evaluate the effectiveness, a strict research design and qualitative improvement of research reports are required, and continuous research should be conducted to develop a systematic protocol.
