The normal children who aged from 6 to 15 in Taegu have been taken X-Ray. The results were compared with the scores of British children which were the results of Tanner`s method. The results are as follow. 1. RUS scores were both in a similar growth, but at 15 years those of British children went up rapidly. However, the skeletal maturity of Korean children was completed 95%. 2. Carpal scores were high in Korean children at 6∼7 years, but after 8 years British children had a rapid tendency in growth velocity. 3. In bone ages, British children were likely to close growth plate at 15 years, and Korean children was completed 95.3%. 4. The ranges of growth in Korean children were 3%, 10%, 50%, 75%, 90%, and 8∼9, 10∼11 years of 3% group were stopped growing. The patterns of the curves in 3% group are very similar with 90% group. The distance difference between two groups was high at 11∼12 years.

The purpose of this study was to identify the learning effect of the rocking chair skill on the fore rolling in elementary school. To achieve the purpose of this study, the 2-class of 3th grade(n=66) and the 2-class of 5th grade(n=72) of K elementary school were chosen by random sampling. And they were divided as experimental group and comparative group. The researcher reorganized the contents of the fore rolling units in the physical education texts and gave 3-hour lessons to students for the fore rolling learning. And the experimental group students learned the rocking chair skill before each lessons. The results of this study can be summarized as follows. First, after 3-hour lessons, there was no differences in average marks between the experimental group and comparative group and the two groups all showed a statistically significant improvements in the fore rolling learning. Second, in analysis of interaction effects on the factors, there was an interaction effects according to the grades and groups. Third, in t-test on the average gap between two groups, the experimental group showed a statistically significant improvements compared to the comparative group in the fore rolling. Fourth, in t-test on the average gap between two grades, the experimental group of 3th grade showed a statistically significant improvements. But in the 5th grade, there was no differences in average marks between the experimental group and comparative group.

본 연구는 재구매의도에 대한 기존연구에서 중요한 결정변수로 연구되어온 고객만족과 서비스 품질 외에 소비정서 및 전환비용을 새롭게 도입하여 기존 고객의 유지전략인 재구매의도의 영향요인을 규명하고자 하였다. 이를 위하여 은행에 거래하는 기업고객들과 기업고객을 담당하고 있는 은행직원으로부터 자료를 수집하여 구조방정식 모형을 이용하여 가설을 검증하였다. 본 연구결과는 다음과 같이 요약된다. 첫째, 재구매의도의 가장 중요한 결정변수는 고객만족으로 제시되고 있다. 둘째, 서비스 품질을 측정 시 서비스가 고객에게 전달되어지는 과정을 의미하는 과정 품질 외에 고객이 서비스로부터 실제로 받거나 또는 서비스 공급자에 의해 전달되어지는 결과 품질을 함께 측정하는 것이 바람직한 것으로 나타났다. 셋째, 긍정적인 소비정서는 고객만족에 정(+)의 영향을, 부정적인 소비정서는 고객만족과 재구매의도에 부(-)의 영향을 미치는 것으로 나타났다. 넷째, 전환비용은 상대적으로 영향력은 크지 않았으나 고객만족, 부정적 소비정서와 함께 재구매의도의 선행요인으로 작용하고 있음을 보여주고 있다. 결론적으로 고객의 재구매의도에 대한 선행요인으로 고객만족과 과정품질의 상대적 영향력이 제일 크게 나타나고 있으며 긍정적 소비정서, 부정적 소비정서, 결과 품질 및 전환비용 역시 기업거래 고객의 재구매의도를 예측하는 변수로 활용될 수 있음을 제안해 주고 있다. In this study, We have newly introduced consumption emotions and switching cost, as a means of managing existing customers, to examine influencing determinants in repurchase intentions along with customer satisfaction and service quality which have been important determinants in previous researches on repurchase intentions. To test them empirically, data from corporate customers of a bank in Korea and corporate banking related bankers are collected and analyzed by LISREL 8.12.. The result of this study can be summed up as follows. First, the most important determinant factor in repurchase intentions is customer satisfaction. Second, it is desirable to measure service quality not only in terms of process service quality, a process of service delivery to customers, but also outcome service quality, what customers receive from services or from service providers. Third, positive consumption emotions have positive influence upon customer satisfaction, negative consumption emotions have negative influence upon customer satisfaction and repurchase intentions. Fourth, switching cost, even though small in its influence, has been proved to be antecedent in repurchase intentions along with customer satisfaction and negative consumption emotions. After research, as precedents in customers' repurchase intentions, customer satisfaction and process service quality have exercised the biggest influences. Also, positive consumption emotions, negative consumption emotions, outcome service quality and switching cost can be used as determinants in predicting corporate customers' repurchase intentions.

Due to the development of electric and hybrid vehicles, the trend has changed from hydraulic power steering system to electric power steering system (EPS). In this paper, design parameters are deduced through the structural analysis based on the finite element analysis for the intermediate shaft of the EPS on the market. By analyzing the design parameters, the structure design is improved to support the required high torque on the EPS. The numerical analysis is performed to obtain the improved design of the intermediate shaft model and the analysis results are compared with the existing model. It is noted through this numerical approach that the improved design of the intermediate shaft can be acquired the structural safety and high stiffness than existing model.
