  • The purpose of this study is to investigate the efficiency of systematic color combination for apparel and textile design. We planned the new color systems, HUE AND TONE COLOR SYSTEM 277 and HUE AND TONE COLOR SYSTEM 253 USED KOREAN TRADITIONAL COLORS. In order to emprove the efficiency, this study aims to explore the development of systematic color combination by computer graphics. With this purpose, this study progressed in the following order and we obtained these results. 1. First, we considered the possibility of the development of the systematic color combination used the new color system, HUE AND TONE COLOR SYSTEM 277. We considered the possibility of the development of the systematic color combination by graphic computer SDS-480. Through the experimental regulation of the RGB (Red, Green, Blue) and HLS (Hue, Lightness, Saturation) we obtained an approximation of the colors of the HUE AND TONE COLOR SYSTEM 277 on the CRT display of SDS-480. 2. We planned the new color system, HUE AND TONE COLOR SYSTEM 253 USED KOREAN TRADITIONAL COLORS for systematic color combination. 3. In a practical application, we tried five principal types of color combination in apparel and textile design, monochromatic combination, tone on tone combination, moderate combination, tonal combination, and contrast combination. 4. Furthermore, we applied the systematic color combination for the textile patterns by tone on tone combination. By using the systematic color combination for apparel and textile design, we realized the efficiency and utility of the systematic color combination.

  • The purposes of this study were to investigate the effects of systematic analogy on pupils' concepts changes compared with non-systematic analogy and no analogy using longuitudal study. The subjects were the second year middle school students(N=140), 49 of them were experimental group, using systematic analogy; 47 of them were control group 1, using non-systematic analogy; and 44 of them were control group 2, using no analogy. We have elicited their ideas about electric current three times: pretest, posttest and delayed posttest by P-O-E(Prediction-Observation-Explanation) method. With time, resistant ;rrelevant idea was decreasing dominantly; sequential reasoning idea and scientific idea were increasing; and current consumption idea was rare. Systematic analogy is more effective than non-systematic analogy on pupils' concepts changes of electric current. Systematic analogy is more effective than no analogy in case of simple situation, but we couldn't find significant difference between systematic analogy and no analogy in case of complicated situation.

  • Hotel consumers tend to rely on online reviews to reduce the risk to hotel products when they book hotel rooms because hotel products are high-risk products due to their intangibility. However, the development of ICT has caused information load, and it is an important issue to be perceived as useful information to consumer because a large amount of information complicates the decision making process of consumers. Drawn from Heuristic-Systematic Model(HSM), the present study explored the role of heuristic and systematic cues composing an online review influencing consumers' perception of hotel online reviews. More specifically, this study identified reviewers' identity, level of the reviewer, review star ratings, and attached hotel photo as heuristic cue, while review length, cognitive level of review and negativity in review as systematic cues. The binary logistic regression was adopted for analysis. This study found that only systematic cues of online review were found to affect the usefulness of it. Moreover, we preceded further study examining the moderating effect of seasonality in the relationships between systematic cues and usefulness.

  • Objective : The purpose of this study is to work on the problems and on the direction of the study regarding the evidence-based study of Acupuncture. Methods : We reviewed the PubMed electronic database. Eight articles of systematic review without meta-analysis and six articles without meta-analysis were selected. Results : In the study of eight articles of systematic review without meta-analysis, there were two articles on effectiveness of acupuncture and one on non-effectiveness of acupuncture. Four articles were about the changes according to the quality of randomized controlled trials. Also, one article was about the side-effect of acupuncture. In the study of six articles of systematic review with meta-analysis, there were two articles on Odds Ratio, two on Relative Risk, one on number-needed-to-treat, and two on 18 predefined methodological criteria. Conclusion : As the quality of RCTs was high, positive response decreased and as the quality of RCTs was low, positive response increased. For the study of evidence-based acupuncture, it is necessary that we conduct research on well-planned placebo acupuncture, large sample size, statistical method, method of searching and assessing literature and method of meta-analysis.

  • Objectives The purpose of this study is to assess the reporting quality and methodological quality of systematic reviews from the Journal of Pediatrics of Korean Medicine. Methods Systematic reviews were selected from the Journal of Pediatrics of Korean Medicine (JPKM) by utilizing Oriental Medicine Advanced Searching Integrated System (OASIS) and JPKM homepage. Two independent researchers assessed the reporting quality through Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline checklist, and assessed the methodological quality of systematic review through Assessment of Multiple Systematic Reviews (AMSTAR) 2 tool checklist. Results Four systematic reviews were finally selected for the assessment. When assessed by PRISMA, three literatures were little insufficient, and one literature was sufficient. When assessed by AMSTAR 2, three literatures were moderate quality, and one literature was critically low quality. Also, all of the reviews had no information about 'Protocol and registration', 'publication bias', and 'conflicts of interest'. Conclusions Systematic review is important for Journal of Pediatrics of Korean Medicine and Korean Medicine Society. Efforts are needed to improve the reporting and methodological quality of the systematic reviews through PRISMA and AMSTAR 2.

  • In this paper, we investigate several variance estimators for pps systematic sampling. Unfortunately, there is no unbiased variance estimators for a systematic sample because systematic sampling can be regarded as a random selection of one cluster. This study provides guidance on which variance estimator may be more appropriate than others in several circumstances. We judge the efficiency of variance estimators for systematic sampling based on of their relative biases and relative mean square error. Also, we investigate variance estimation problems for two-stage systematic sampling applied for the Food Raw Material Consumption Survey and the Establishment Labor Force Survey simulation study, in order to consider the popular two-stage pps systematic sample design for establishment and household survey in Korea.

  • The purpose of this study is to explore the applying possibility of the Earth Systems Education(ESE) in elementary school science education through the improving of students' recognition with the earth systematic nature by systems thinking education - for this was the recognizing as earth systematic nature was the key element of ESE, and the systems thinking skill is accredited very effective tool for the understanding with earth systematic nature. For this, the systems thinking's teaching-learning programs were developed and applied to the 6th students (21s) for 10hours' classes. The results of this study are as follows; In most of the 6th students didn't recognize with earth systematic nature from a lack of understanding of the vapor being in every nature environments. In systems teaching-learning classes, most of students participated positively in learning activities and achieved the aim of a lesson. In the testing results for students' recognition improving to earth systematic nature after the systems thinking education, about 24% students were showed the improving results of the recognition with earth systematic nature. Consequently, It is suggested that just as the achieving of the points of ESE in elementary school science education, the approaching method of the systems thinking education is worth attempting to applying of the ESE.
