The purpose of this study is to provide the valuable basic information that helps set the advanced direction of study in environmental pollution in the future. It classifies and analyzes 6, 531 papers according to their years, fields, and contents from 1962 to 1993 in Korea through Chunrian, a PC communication network, National Environment Research Institute(1989) in Seoul. Classifying papers by their fields, this study shows 19.6%(1, 281 papers) of total papers on water pollution, on which most emphasis was placed in the studies, 17.2%(1, 121 papers) on general remarks, 14.6%(952 papers) on environmental ecology, and 13.6%(891 papers) on air pollution. Classifying papers by their contents, this study tells us that the survey of state and evaluation of pollution degree took 28%(1, 829 papers) of total papers, and it seemed the most active study was carried out on this content. It then shows us that the treatment technology and mechanism shared 17.5%(1, 144 papers), and facilities and design took 1.9%(127 papers) which needed more studies in the future. As for the trends of study, the papers published until 1979 show that the water pollution accounted for 28.9% of total studies, on which the greatest emphasis was placed, while the papers in 1990s tell us that general remarks 34.7%, air pollution 14.9%, and water pollution 14.1%. It also shows that treatment technology and mechanism has had more importance since 1980s in water pollution, noise and vibration, waste materials, human wastes, and radioactive pollution. However, in sea pollution, policy and standard rather than treatment technology or method of measurement and analysis has been considered a more important one in 1990s. Analyzing the studies on general remarks, it tell us that the paper on environmental act, which were frequently conducted, accounted for 33.3% until 1979, while the papers on the environmental policy, in which the highest interest was kept, accounted 34.6% in 1990s. This study concludes that most papers had examined the survey on status and evaluation of pollution degree before 1980, while studies on solving the problems of environmental pollution have had more importance in the 1980s and 1990s. Therefore, in the future, more studies should be conducted actively on policy development to solve the problems of environment pollution as well as on encouragement of environmental consciousness.

From January 1983 to December 1992, There were 1441 papers in the Korean Journal of Thoracic and Cardiovascular Surgery. Among these papers, 783[54.3%] were original article or clinical analysis and 652[45.2%] were case reports. A total of 319 papers contained some statistical analysis. In 150 cases[47.0%] of these 319 papers, the statistical description was insufficient. Of the correctly described papers, 115[68%] had more than one statistical error. Of course, in many cases the errors were not considered to be severe, but they were often sufficient to raise doubts about some inferences. We suggest that authors should be more careful when they describe and apply statistical methods. If possible, authors should interpret results with statistical specialists. And we also suggest that our society have more extensive statistical refereeing system. This would at least prevent the worst errors from appearing in print. The last suggestion is elementary instruction in statistical methods during preclinical training.

Objectives : The aim of this review was to analyse the study tendency in papers related with Ssanghwa-tang which are published in Korea from 2000 to 2019. Methods : We searched the four electronic database (NSDL, RISS, Korean traditional knowledge portal, OASIS) and checked relevant Korean journals from 2000 to 2019. We classified the papers by publish date, speciality, study method, and field of study, and analysed the study tendency. Result : 1. papers were published annually on average. 2. After classifying papers by the speciality of journal, continuous study was followed not only in korean medicine, but also in many specialities like Dietetics, Pharmacology and Tourism management. 3. In study methods, in vivo was 46%, quantitative inspection was 21%, and in vitro was 19%. 4. After classifying papers by field of study, efficacy was 49%, qualitative analysis was 27%, toxicity was 14%, and safety was 5%. 5. In efficacy, it was effective in muscloskeletal disease, cardiovascular disease, prevention of neurologic disease, antioxidation, immunization disease and so on. Conclusions : These results suggest that Ssanghwa-tang can be used as cure medicine, not just as herbal tonic, but there are not sufficient evidence based papers, so there should be further studies in order to establish Ssanghwa-tang as a cure medicine.

Objectives: Genital herpes is common disease in gynecological field. Although various treatment options such as herbal medicine, acupuncture, moxibustion are used in genital herpes, there is not enough evidence about the treatment options. This study is to prove the efficacy of oriental medicine on genital herpes by investigating papers and suggest direction of future research. Method: We searched for papers which had both genital herpes and oriental medicine from Cochrane, Pubmed, Scopus, CNKI, Oasis, Korean traditional knowledge portal, Journal of Korean Obstetrics & Gynecology up to November 2017. After searching papers, we classified according to the study design and analyzed selected studies. Results: Sixteen papers were finally selected. Four papers are laboratory studies with Hartley guinea pig with recurrent genital herpes. Twelve papers are clinical trials which includes one single group trial, one controlled trial, ten randomized controlled trials. All of the studies have shown that herbal medicine is effective in improving the symptom of genital herpes and decreasing the recurrent rate of genital herpes and also has immunoregulatory effect. Conclusions: This study shows that herbal medicine could be a good treatment option for genital herpes. However, more well-designed clinical studies and laboratory studies will be needed.

The present study explored studies directed at elucidating the effectiveness of Korean medicine in the treatment of sterility and systematically analyzed the trends of studies on sterility. The standardization and objectification based on results for this study may contribute to the development of effective Korean medicine in reducing sterility. In the annual tendency of sterility-related clinical studies, the number of papers began to increase rapidly from 2000, and 15 papers were published from 2000 till 2011. Then, in the technical journals publishing them, The Journal of Oriental Obstetrics & Gynecology published 13 the most papers. In the institutions to which the first authors belonged, Dongguk University Hospital had 5 the most papers. In the number of test subjects was also analyzed and as the result the studies with 1~9 were the most as 10. In the study design analysis, there were 10 case reports, 5 case series and 4 before and after studies. In the analysis of intervention methods, there were 10 papers where only the Korean medicines were given, next 6 papers where the acupuncture and moxibustion were added, and 3 papers where the Korean medical therapies and other subsidiary therapies were used. In the analysis on the existence of pattern identification, there were 12 papers with the pattern identification, 6 without the pattern identification and 1 with the four constitution identification. In the IRB approval, 18 or most papers had not received the IRB approval and just 1 paper got the IRB approval. When the sterility-related clinical studies published in the Korean medical journals were surveyed, it turned out that there are no RCT studies and there is just one study with the IRB approval. And there were 6 papers without the pattern identification of Korean medicine. So, it seems necessary in the future to improve the papers in these respects for the development of Korean medicine sterility treatment with a good basis through the more systematic and accurate study method.

The purpose of this study is to assess the suitability of the statistical techniques employed in papers published in the Korean Journal of Veterinary Research from March 1997 to March 1999 and it is hoped that the critical assessment may be of help to other researchers preparing their works for publication. Of the 246 original papers 94 were included in the analysis. Of 62 papers with the measure of central location and dispersion of data 34 (54.8%) used them correctly : 9 (39.1%) of 23 for t-test ; 1 (33.3%) of 3 for correlation analysis ; 7 (43.8%) of 16 for analysis of variance (ANOVA) ; 5 (62.5%) of 8 for chi-square test ; 44 (71%) of 62 for description of p-value. A number of papers employed ANOVA did not perform subsequent analysis of multiple comparison. Compared to the results of others, relatively higher proportion of papers in the present study was evaluated as appropriate analysis. The reason is that papers described insufficiently on the study design were not included, and evaluation items were restricted to the cases violated seriously inherent assumptions for each statistical technique. Statistical misuse or abuse appeared in the study is due to lack of knowledge on statistics and short of its importance for improvement the quality of paper. Because an inappropriate analysis can lead the readers to misunderstand on findings, observed statistical analyses must be valid, and correctly undertaken. It is suggested that more intensive statistical refereeing are needed, and the communication should be allowed for the controversial points.

Hanji, the korean traditional papers were mostly made from mulberry paper. But the production and demand of hanji have decreased rapidly because mulberry paper yields were insufficient and handworked hanji procedures were complicated. Recently, the researches on hanji were carried out to improve the properties of hanji. Kenaf fibers have been interested as a substitute resource of mulberry paper for hanji production. In this research, Kenai pulps were manufactured with removal methods of lignin or hemicellulose from kenaf fibers and paper mulberry pulps with traditional alkali methods. Kenaf papers, paper mulberry, and kenaf/paper mulberry mixed papers were manufactured with their pulps. The crystallinity, fiber length, color of the pulps and tensile strength, tear strength, water absorption of the papers were investigated. The results were as follow: The removal rates of lignin of chemical retted kenaf fibers with sodium chlorite reaction for 40 minutes were 70% and were higher than 40% of double retted fibers. Paper mulberry pulps has less lignin and hemicellulose than kenaf differently. The crystallinity of paper mulberry pulps were very low with 60%, but kenaf pulps were 90%. The chemical retted CR-40-1 pulps were similar with paper mulberry pulps on fiber length & fibrilation of fibers. Tensile strength of paper mulberry were higher than kenaf papers because of fibrilation of paper mulberry, but tear strength were lower. Tensile strength and tear strength were improved on kenaf/paper mulberry 30/70 mixed papers.
