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.

In order to teach the nature of science which is one of the goals of science education, the aesthetic model of science was developed into a two-dimensional model through theoretical reviews on the aesthetic aspect of science. We represented 10 kinds of scientific experiments that scientists thought are beautiful in the aesthetic space of science. This paper tried to represent the greatest and famous scientific experiments in the history of science into the aesthetic space of science to find the suitability or usefulness of that model. At the same time, we were able to develop measuring tools as the Likert-scale with pictures of scientific experiments. Through this, we propose various teaching approaches on the nature of science (NOS) based on the aesthetic model of science and the potential for utilization in measuring the effects of the ways of teaching NOS.

The purpose of this study was to explore the importance level, the present level, and the educational need for 21 business ethics components among 2-year and 4-year college students majoring in fashion. Survey data of 364 students (128 students of 2-year colleges and 238 students of 4-year colleges) were analyzed through descriptive statistics, Borich's needs assessment for education, The Locus for Focus model, exploratory factor analysis, and t-test. The results showed five business ethics components ranked highly as educational needs among college students: 'reducing waste', 'using vegan materials', 'using human-friendly materials', 'strengthening sustainable technologies', and 'promoting workers' rights'. Those components should be integrated into curricula of fashion majors in colleges. Students in 4-year colleges considered most of 21 business ethics components as more important than did students at 2-year colleges. More needs for education were observed by 4-year college students in eight business ethics components than by 2-year college students. In addition, a positive attitude toward business ethics education and the suitability of business ethics education were higher among 4-year college students than 2-year college students. Results provide a guideline for business ethics education by indicating a list of business ethics components that urgently needed to be adapted to fashion curricula according to each college type.

With the development of synthetic dyes, excellent dyeing properties and massive production became possible. On the other hand, natural dyeing technology has gradually disappeared. However, the international environmental and human safety requirements of the apparel and textile industry are increasing, and there is a growing interest in safer and more environmentally friendly products. Accordingly, the public's interest in natural dyeing is increasing. To meet these demands, it is first necessary to clarify the stages of production and distribution of natural dyes. It is necessary to evaluate whether the product is a natural dye product and study the suitability of the natural dye product through qualitative and quantitative assessment of the indicator components of the natural dye. Typical of three natural dyes did qualitative and quantitative analysis by HPLC-DAD and HPLC-MS. Products dyed using natural dye three products were analyzed, and the presence or absence of detection of each indicator components was confirmed to confirm whether the product was dyed using natural dyes.

This study carried out a horticultural program for people with mental disabilities to determine suitability of the horticultural activity program and to actually apply to vocational rehabilitation. The program was carried out in 16 sessions from April 12 to June 7, 2018 with nine people with a strong will to participate in vocational rehabilitation at a health center for persons with mental disabilities. The tools used were the Horticultural Activity Performance Assessment (psychological behavior) and Purdue Pegboard Test that examines functions of hands and arms. The subjects sold the products they made during class time and obtained the profits. After the program, the scores increased with a significant difference (p = .000) in the psychological behavior area of the Horticultural Activity Performance Assessment. Hand and arm movement also showed continuous improvement along the program with a significant difference (p = .000), as well as finger dexterity also with a significant difference (p = .018). The net profit was 314,000 KRW (subtracting cost of goods 314,000 KRW from total sales 628,000 KRW). The profit was shared equally among the nine subjects, each receiving 34,900 KRW. Therefore this study proved horticultural activity class is suitable for vocational rehabilitation of people with mental disabilities proved by the positive effects. We also expect that the subjects will be able to make more profits if they learn more skills, since they are interested the process of making such profits.

Objectives: To explore prevalently used types of medication error and the types of medication error which would be appropriate to be used in Korea. Methods: In depth literature review was performed to explore the mostly used types of medication error in the United States, Canada, Europe, Australia, and Japan. We intended to examine experts' view on the suitability of the types of medication error to be used in Korea. The types of medicati0on error were classified by activity criteria, severity criteria, process criteria, and responsible person criteria based on literature reviews. Results: According to the result of literature review, activity criteria was the most commonly used type of medication error. Ten experts in the area of patient-safety and medication error responded and the top two types of medication error which were appropriate and suitable to be used in Korea were severity criteria and activity criteria. Conclusion: Severity criteria and activity criteria could be recommended to be used as the standard types of medication error in Korea although there are other types of criteria such as process criteria and responsible person criteria.

Zooplankton biomass is essential for understanding the quantitative structure of lake food webs and for the functional assessment of biotic interactions. In this study, we aimed to propose a biomass (dry weight) estimation method using the body length of cyclopoid copepods. These copepods play an important role as omnivores in lake zooplankton communities and contribute significantly to biomass. We validated several previously proposed estimation equations against direct measurements and compared the suitability of prosomal length versus total length of copepods to suggest a more appropriate estimation equation. After comparing the regression analysis results of various candidate equations with the actual values measured on a microbalance-using the coefficient of variation, mean absolute error, and coefficient of determination-it was determined that the Total Length-DW exponential regression equation [W=0.7775×e^2.0183L; W (㎍), L (mm)] could be used to calculate biomass with higher accuracy. However, considering practical issues such as the morphological similarity between species and genera of copepods and the limitations of classifying copepodid stages, we derived a general regression equation for the pooled copepod community rather than a species-specific regression equation.

Korea has 30 years of experiences in environmental impact assessment (EIA). Although EIA includes sanitation-public health factor, considering health impacts, among 74 unit projects of 17 sections, health impacts haven't been properly considered or have been ignored in many cases. The increasing awareness on the importance of health impacts has triggered this study to seek an optimal introduction scheme of health impact assessment (HIA). The processes of EIA already include screening, scoping, analysis, impact assessment, consultation, document review, decision making and monitoring, in which they would be the essential parts of HIA. In this context, integrating HIA into the existing EIA process could be the most effective way to use the benefits in both legal and procedural processes existed and to avoid the confusion and overlapping since the close relationships between environment and health impacts might be. Furthermore, it is desirable that the existing sanitation-public health factor should be substituted by and extended to environment-health factor with sufficient determinants to properly consider health impacts. When considering the first step of HIA, the prospective and qualitative approach is suitable more than the retrospective and quantitative one due to the lack of database accumulated. Similarly, an approach based on epidemiology and toxicology could analyze the limited evidences and impacts related to human disease, whereas one based on socio-science and psychology could provide the effective means available for predicting how the people and community will act by the change of surroundings. Checklist approach with various and comprehensive health determinants focused on prospective and qualitative methods will be very useful for more convenient and progressive dissemination of HIA. Various checklist approaches of toolkits could be found from HIA documents elsewhere, for example Westminster Toolkit, and they would be helpful to figure out how to develop common procedures and health determinants for checklist, in which the unique characteristics on korean cultural and political context compared to abroad should be carefully considered since checklist would be the most basic and essential part of HIA. After the establishment of checklist and procedural processes, the pilot projects should be conducted. Main purpose of pilot projects is to apparently prove the effectiveness and profitability of HIA. Pilot projects should be implemented to decide the effectiveness and suitability of HIA for future projects, programs and policies, and should be provided as the positive cases that can be achieved through the proper implementation and progress.
