이단계 이수준 균형지분모형에서 주효과 및 지분효과를 검정하기 위한 모수적 검정과 순위변환을 이용한 검정은 전반적으로 제1종 오류율이 상당히 유사하며, 주효과 및 지분효과를 검정하기 위한 순위변환통계량의 검정력은 모수적 통계량의 검정력보다 상대적으로 뛰어난 수준임을 보여준다. 한편 효과의 크기와 표본의 크기를 증가시킬수록 모수적 통계량과 순위변환 통계량의 검정력 증가량의 크기는 현저하게 향상되며, 특히 지수분포와 같은 비대칭분포하에서 모든 인자가 고정일때 순위변환 통계량의 검정력이 모수적 통계량의 검정력보다 월등히 높은 수준임을 나타낸다.

1. Objectives The main ingredient of ephedra is ephedrine which affects on autonomic nervous system induce some adverse effects just like vasoconstriction, hypertension, tachycardia, miosis, insomnia, dizziness, headache, and etc. and heart disease. If we use Mahuang according to the Sasang constitution classification in clinic, we could not only may minimize the anxiety but maximize the potential curative value in Asthma Treatment. 2. Methods On a day three times in Mahangjungchentang taken patients who with Ventricular septal defect in the aftermath of the RBBB. We are observed that the main symptoms of change, vital sign, sleep, stool, urine, heart disease. 3. Results Teaumin with asthma, the effect of Mahuang, and the side effects are fewer. The individual effects of herbs are important. but Sasang constitutional effects are important too. 4 Conclusions Mahuang can increase heart disease. But there was a difference among Sasang constitution classification. This has no side effects from Teaumin than other constitutions. If we use Mahuang according to the Sasang constitution classification in clinic. We have an excellent effect on the treatment of asthma.

The effects of suspension stiffness on the reaction load of the gearbox suspension for a three-point suspension wind turbine drive train were investigated by finite element analysis. The reaction forces of the gearbox suspension appear to increase as the gearbox suspension stiffness increases; however, the main bearing stiffness has a reverse effect on the reaction forces. The influence of the gearbox suspension stiffness is greater than that of the main bearing. Since the suspensions must provide the gearbox with proper support, it is not practical to use soft gearbox suspension for small reaction forces. It is more feasible to use stiff main bearings. As a guideline for the main bearing stiffness in the present study, we propose a relative stiffness of 100-150% of the reference.

Host-pathogen interaction in rice bacterial blight pathosystem was analyzed for a better understanding of their relationship and recognition of stable pathogenicity among the populations of Xanthomonas oryzae pv. oryzae. A total number of 52 bacterial strains isolated from diseased leaf samples collected from 12 rice growing states and one Union Territory of India, were inoculated on 16 rice varieties, each possessing known genes for resistance. Analysis of variance revealed that the host genotypes(G) accounted for largest(78.4%) proportion of the total sum of squares(SS), followed by 16.5% due to the pathogen isolates(I) and 5.1% due to the $I{\times}G$ interactions. Application of the Additive Main effects and Multiplicative Interaction(AMMI) model revealed that the first two interaction principal component axes(IPCA) accounted for 66.8% and 21.5% of the interaction SS, respectively. The biplot generated using the isolate and genotypic scores of the first two IPCAs revealed groups of host genotypes and pathogen isolates falling into four sectors. A group of five isolates with high virulence, high absolute IPCA-1 scores, moderate IPCA-2 scores, low AMMI stability index '$D_i$' values and minimal deviations from additive main effects displayed in AMMI biplot as well as response plot, were identified as possessing stable pathogenicity across 16 host genotypes. The largest group of 27 isolates with low virulence, small IPCA-1 as well as IPCA-2 scores, low $D_i$ values and minimal deviations from additive main effect predictions, possessed stable pathogenicity for low virulence. The AMMI analysis and biplot display facilitated in a better understanding of the host-pathogen interaction, adaptability of pathogen isolates to specific host genotypes, identification of isolates showing stable pathogenicity and most discriminating host genotypes, which could be useful in location specific breeding programs aiming at deployment of resistant host genotypes in bacterial blight disease control strategies.

This Research aims to analyze the effects of SCM management capabilities and IT capabilities on firm performance. The strategic performance was shown to be positively and significantly affected by flexibility and responsiveness which were proxies for SCM management capabilities. However, neither main effect of IT capability nor interaction effects of IT capability and SCM management capability on firm performance was found.

Objectives: The purpose of this study is to investigate the effects of Sa-am acupuncture with Pericardium jung-gyuck (SA-acu-PC) and Triple Energizer jung-gyuck (SA-acu-TE) on the radial pulse in healthy human subjects. Methods: Sixty healthy subjects participated in this study and divided into three groups randomly: Control group(C), Pericardium jung-gyuck group(PC), Triple Energizer jung-gyuck group(TE). Radial pulse was measured by 3 dimensional pulse imaging system (DMP-3000) before, right after, 30 minutes after, and 60 minutes after acupuncture. Results: 1. The changes observed in periodic parameters are considered as the common effects of both SA-acu-TE and SA-acu-PC. SA-acu-TE was more effective than SA-acu-PC in these effects. 2. The effects of SA-acu-PC appeared in the pulse amplitude, pulse area, and pulse power volume mainly at the left chon position, and 3. The effects of SA-acu-TE appeared in the radial augmentation index and main peak angle mainly at the right gwan position. Conclusions: The effects of SA-acu-PC and SA-acu-TE can be observed in the radial pulse. The increases in pulse amplitude, pulse area, and pulse power volume at the left chon may imply the effects of SA-acu-PC. And the decrease in the pulse power volume, the increases in radial augmentation index and main peak angle may imply the effects of SA-acu-TE.

Purpose - In the present study, it has become the most important necessity in our daily lives that consumers' psychological factors affect the use of smartphones, and it has been analyzed through behavioral economic approaches. In this respect, the present study is intended to apply the heuristic theory and the prospect theory among behavioral economics theories to examine how psychological factors affect consumers' product selection. Research design, data, and methodology - In the present study, using smartphone repurchase as a dependent variable, whether regulatory focus effects have interaction effects on behavioral economic theories and behavioral economic effects such as possession (ownership) effects, framing effects, and brand recollection. As an analysis method, questionnaire surveys conducted with university students in Incheon were examined through Two-Way ANOVAs using the SPSS23 package. Results - The analysis from the results are as follows. Using smartphone repurchase as a dependent variable, the main effects and interaction effects on two variables; satisfaction difference with product functions and positive framing variable were statistically significant. Using repurchase as a dependent variable was statistically significant, there was no interaction effect between the two variables; satisfaction difference with product functions and the difference of brands in possession. Using smartphone repurchase as a dependent variable, interaction effects on two variables; satisfaction difference with product functions and the lengths of product possession periods were not statistically significant. The results from the analyses of interaction effects of brand recollection and brands type were statistically significant in possession using repurchase as a dependent variable. The results from the analyses of the main effect of the brands type were statistically significant in possession using repurchase as a dependent variable. Conclusions - The implication of the present study is that it suggests the factors that became important for customers' smartphone purchase following the change in the meaning of smartphones from practical products in the past to hedonic products. Limitations of the present study are first, the study subjects are limited to students and the number of copies in questionnaires is only approximately 130, which is insufficient, so that the present study is not sufficient as a study for entire smartphone users.
