In this paper, The impulse un-tripping characteristics and the electro magnetic compatibility characteristics are compared with each other. The performance of impulse un-tripping test exists at domestic standard (KSC 4613). However test items are insufficient because the more test items such as EMC exist at international standard (IEC). Also, Electric Appliances Safety Certificate has taken the certificate test since July 2004 in Korea but did not confirm the EMC performance for RCCBs made in Korea. Thus, in this paper, We experiment with Oscillatory waves immunity test and the 7 EMC tests for 32 RCCBs of 4 types (mini, home standard, plug, outlet) for 16 brands according to IEC standard 61009-1 and 61008-1. As a result, 24 RCCBs proved to be poor for surge immunity test. However the RCCBs operating incorrectly for surge immunity test operate correctly for oscillatory waves immunity test. Thus, the correlation between oscillatory waves immunity test and EMC test is little and standard for compatibility of combination surge at IEC 61000-4-5 should be added to KS standard as soon as possible.

일반적으로 각 N개의 모집단에서 2개 이상의 표본이 추출되었을 때, $H_0:{\mu}_1={\cdots}={\mu}_N$의 가설에 대하여 검정할 수 있지만 각 모집단으로부터 표본이 한 개씩 추출된다면 ${\bar{X}}$가 존재하지 않으므로 모평균의 차이 검정은 불가능하다. 하지만 하나씩 추출된 표본으로 구성된 집단을 두 집단으로 나누어 임의의 평균을 생성함으로써 평균의 차이를 비교한다면 표본들 사이에 존재할 수 있는 이질성을 파악할 수 있다. 따라서 우리는 두 집단으로 나눌 수 있는 조합의 수만큼 평균 차이를 검정할 수 있는 최소 조합 t-검정 방법을 제안하고자 한다. 최종적으로 본 논문에서는 한 개씩 추출된 표본들 사이의 이질성을 확인하기 위하여 평균 차이를 검정할 수 있는 방법을 제안하였고 모의실험 연구를 통해 성능을 확인하였고 실제 자료 분석을 통해 결과를 도출하였다.

In this study, the characteristics of the Mock-up test were reviewed to analyze the applicability of the coal gasification slag (CGS) from the integrated gasification combination Cycle (IGCC) to the concrete fine aggregate. The analysis shows that CGS and crushed sand mix is the best combination of CGS combined with about 50 % of CGS based on the effects of promoting liquidity and strength. This is expected to be a positive factor in securing the strength and flexibility of concrete given the optimal mix of CGS, and may also contribute to the improvement of quality.

Objectives: This study aims to determine the Fractional Inhibitory Concentration Index (FICI) of combinations of Melastoma malabathricum leaf fraction with ciprofloxacin or gentamicin against pathogenic bacteria, Escherichia coli, Staphylococcus aureus, and Bacillus cereus, isolated from Diabetic Foot Ulcer (DFU) patients. Methods: We tested concentrations of 45%, 55%, 65%, and 75% of gentamicin and ciprofloxacin using dilution and agar diffusion methods. The combination of M. malabathricum leaf extract with these antibiotics was tested in vitro against all three bacteria. Results: The combination of M. malabathricum leaf extract and ciprofloxacin gave a FICI value of 0.5, indicating synergistic antibacterial activity against the test bacteria. Conclusion: The results show that the antibacterial effect of a combination of high doses of the leaf extract with either antibiotic is greater than that of the leaf extract and the antibiotics in single use.

The purpose of this study is to evaluate the combination of tailored suit details through visual evaluation which helps compensating middle aged women＇s body defects for their more attractive fashion styles. The data evaluated by a multiple ranking test were analyzed using mean, paired t-test, general linear measure and Duncan＇s multiple raged test. The results of this study are as follows: 1) The middle aged woman wearing the opened flap pocket-jacket and slacks looks longer(p〈0.001) in lower part of her body and taller(P〈0.01) as a whole than when wearing others. And, opened jacket makes a middle aged woman be seen with less appeared abdomen(p〈0.01) than that wearing others. 2) The middle aged woman wearing the opened flap pocket-jacket and skirt looks more elegant(p〈0.001), more graceful(p〈0.001), and a bit more balanced(p〈0.05) than that wearing the opened flap pocket-jacket and slacks suits. According to situation(TPO). the middle aged women wearing the opened flap pocket-jacket, and slacks or skirt looks more effective the visual effect in combination of details on Tailored suits.

The purpose of this study is to evaluate the combination of suit details through visual evaluation which helps compensating the classic style suits-middle aged women's body construct for their more attractive fashion styles. The styles of the evaluated suits are formal and classical. The designs of evaluated suits are manipulated in 40 different kinds by the essential elements such as collars, necklines(tailored collars, soutien collars, stand collars, round necklines, V-necklines, etc.), bottoms(slacks, skirts), pocket (flap pocket, none) and opening(opened, closed). The data evaluated by a multiple ranking test were analyzed by paired t-test, ANOVA and Duncan's multiple raged test. The results are summarized as follows : 1. A middle aged woman on skirts suits look more graceful, more elegant, and a bit more refined than that on slacks suits. 2. A middle aged woman wearing a jacket with flap pockets on looks more balanced, and graceful than when wearing with no pockets. 3. Wearing closed jackets looks more balanced and graceful than on opened jackets. 4. The types of collar·necklines can be called the details which put much influence on Image effects. Putting on tailored collar suits is the most graceful, refined, balanced and harmonious case than any others.

The activities of s-amylase, ${\alpha}-amylase$ and protease of three combination products containing digestive enzymes, antacids and herbal drugs on the Korean market were estimated. The effects of antacids and herbal drugs on the activities of digestive enzymes were investigated. Starch-saccarifying activity of s-amylase, starch-dextrinizing activity of ${\alpha}-amylase$ and protein-peptic activity of protease were estimated by Somogy, Mc'Credy, and Casein-Folin method, respectivley. The optimal pH of s-amylase, ${\alpha}-amylase$ and protease were pH 5.0, 4.8 and 7.0, rcspectively. The digestive activities at optimal pH continued about eight hours. The digestive activities of individual enzymes were reduced to 40-90% by antacids and were affected somewhat positively or negatively by herbal drugs. Enzyme activities of the combination products were also affected by pH and reaction time.

Purpose : This study aimed to compare the effect of two modes (proprioceptive neuromuscular facilitation combination patterns and ball exercise) of low back stability for chronic low back patients. Methods : The subjects were recruited fourty patients who had low back pain. All subjects were randomly assigned to PNF combination patterns group, ball exercise group. Measurements were performed fourtimes: pre test, 2weeks, 4weeks, and 6weeks. Main outcome measures comprised the visual analogue scale(VAS), balance performance monitor(BPM). Results : The results were as follows. In the comparison of VAS score, sway area, sway path, and sway velocity according treatment period, score was significantly reduced in both PNF combination pattern group and ball exercise group. In the comparison of the both VAS and sway area between groups, there were significant. PNF combination pattern group significantly more decrease than ball exercise group at 6 weeks. However, both sway path and sway max velocity between group, there were not significantly. Conclusion : These results of this study indicated that PNF combination pattern which performed for six weeks had a significant influence than ball exercise group on low back pain.
