The purpose of this study was to investigate the kinematical analysis on the running motion of elementary students. The subject of this study was 12 healthy elementary students. A scholastic year were divided into 2 group : high group[6 grade], middle group[3 grade]. The following findings are obtained: It's appear that time ratio of the stance and swing in running motion about high group was 56% vs 44%, and this result was effected to wide step and stride length. Also, it's appear that displacement of center of gravity about high group was larger than middle group, and this result was effected to the horizontal velocity of center of gravity. Trunk angle was slanted to the running direction and upper arm rotation in shoulder angle was larger than middle group. And then this result was effected to the lower extremity movement. It's appear that time ratio of the stance and swing in running motion about middle group was 61% vs 39%, and this result was positively effected to narrow step and stride length. Also, it's appear that displacement of center of gravity about middle group was less than high group, and this result was effected to the low horizontal velocity of center of gravity. Trunk angle was slanted to the running direction and upper arm rotation in shoulder angle was less than high group. And then this result was negatively effected to the lower extremity movement.

The purpose of this study is to show the component and anticipation factors of loyalty and word-of-mouth. Specifically, hypothesis is that trust in a salesperson will influence satisfaction with the salesperson, and the store. And the satisfactions with the salesperson and the store will influence the loyalty to the salesperson and the store. Another hypothesis is that loyalty to a salesperson and a store will influence word-of-mouth. Scale items used in this study were selected from developed scales and were adapted to conforming to the selling situation in the service setting. factor analysis and Cronbach's alpha test were accomplished. A total of 703 samples was used to test the hypotheses. The primary method of statistical analysis to test the hypotheses was a structural equation modeling on LISREL 8.3. The results of the study are as follows: First, trust had an influence en satisfaction with a salesperson and a store. Second, the results suggested that satisfaction with the salesperson and the store influences loyalty to the salesperson and the store. Finally, loyalty to the salesperson and the store influenced word-of-mouth, as predicted.

The author present a modified multi-loop algorithm including feedforward for controlling a 55kW step down chopper in the power supply of Maglev. The control law for the duty cycle consists of three terms. The first is the feedforward term which compensates for variations in the input voltage. The second term consists of the difference between the slowly moving inductor current and output current. The third term consists of proportional and integral terms involving the perturbation in the output voltage. This perturvation is derived by subtracting the desired output voltage from the actual output voltage. The proportional and integral action stabilizes the system and minimizes output voltage error. In order to verify the validity of the proposed multi-loop controller, simulation study was tried using Matlab simulink.

본 연구의 목적은 중등 가정과 교사들의 다문화적 태도, 다문화 교육 실천 효능감, 다문화 교육 목표 관점에 대한 인식을 조사하고, 세 하위척도가 각각 어떠한 상관관계가 있는지 알아본 것이다. 연구 대상은 중등 가정과 교사들 130명이며, 양적 연구를 통해 분석한 결과는 다음과 같다. 첫째, 중등 가정과 교사들은 현행 교육과정에서 다문화주의와 다양성을 미흡하게 다루고 있다 고 인식하고 있었으나, 다문화 관련 학부 수강 경험이 거의 없거나 연수를 받지 않은 것으로 나타났다. 이에 다문화 교육을 위한 교사 교육의 강화가 시급하다. 둘째, 중등 가정과 교사들은 다문화 교육 실천 효능감에 대한 인식들 중에서 다문화 교실에 적합한 학습 자료의 개발과 수업방법 적용 측면에서 특히 낮은 효능감을 나타내었으며, 이에 대한 교사 의 자발적인 노력과 행정적인 지원이 수반 되어야 할 것이다. 셋째, 중등 가정과 교사들의 다문화 교육 목표에 대한 관점은 사회적 행동 지향적, 배려중심 지 향적 목표를 중점적으로 동의하는 것으로 나타났다. 넷째, 다문화적 태도, 다문화 교육 실천 효능감, 다문화 교육 목표에 대한 관점의 상관관계를 살 펴본 결과, 사회적 행동 지향적 목표는 다문화적 태도에, 배려중심 지향적 목표는 다문화교육 실천 효능감에 영향을 주는 예측변인으로 나타났고, 다문화적 태도와 다문화 교육 실천 효능감이 사회 적 행동 지향적 목표와 배려 중심 지향적 목표에 영향을 주는 예측변인으로 나타났다. 그러므로 교 사들이 추구해야 할 목표는 현상유지의 관점을 공유하는 것이 아닌 변혁적인 교실 수업을 지향하는 관점을 추구해야 할 것이다. This study is intended to investigate Homes Economics teachers' multicultural attitudes and teaching practice self-efficacy, and their awareness of the objectives of multi-cultural education. The study also aims to find how these three elements are correlated with each other. For these purposes, one hundred thirty Homes Economics teachers were surveyed employing a questionnaire and the data obtained were analyzed quantitatively. The main findings are as follows. First, Homes Economics teachers perceived that the current curriculum does not deal with multiculturalism and diversity sufficiently. However, they took few courses related to multiculturalism in their undergraduate courses. They also had few opportunities of being trained on multiculturalism since they started to work as teachers. Thus, it is urgent for teachers to be educated or trained in multiculturalism. Second, as for their perception of teaching practice self efficacy of multiculturalism, Homes Economics teachers showed a low level of self efficacy especially in developing and applying teaching materials and methods suitable for multicultural classes. Therefore, Homes Economics teachers are required to make voluntary efforts to create and practice multicultural teaching materials and methods. In addition, administrative support is urgently needed to promote their efforts. Third, as for Homes Economics teachers' perspectives on the objectives of multicultural education, theyprimarily agreed to objectives oriented toward social behaviors and considerateness. Finally, an examination of the correlation between Homes Economics teachers' multicultural attitudes, their multicultural teaching efficacy and their perspectives of objectives for multicultural education led to the following: the objective oriented toward social behaviors was found to be a prediction variable of multicultural attitudes, and the objective oriented to considerateness was shown to be a prediction variable of multicultural efficacy. Therefore, Homes Economics teachers are required to have the perspective of seeking innovative classes instead of sharing the perspective of maintaining the current status.

The purpose of this study was to evaluate the effects in respire-circulatory function and cadio-pulmonary endurance capacity. Twelve females(trained 6, untrained 6) participated in dancesport program that is 90min/day, 2day/week for 20weeks. The results were obtained as follow : 1. No significant difference was found in heart rate, ventilation and respiration rate among pretest, after 10 weeks and 20 weeks of dance program and between trained and untrained group. 2. Significant differenced was found in VCO₂between pretest and 20Weeks later in untrained group. 3. There was significantly increased VO₂max in 20 weeks dance program later compared with pretest and significant difference between groups. 4. There was no significant difference in ventilatory threshold and exercise time was not significant difference among trials and between groups. Conclusively, respiro-circulatory function and cardio-pulmonary endurance capacity were not changed at submaximal stage of excise test but those were significantly increased at maximal of exercise test during 20 weeks. Therefore, it is suggested that long term dancesport exercise program is expected more effective on the repiro-circulation function and cardio-pulmonary endurance capacity.

목적: HBV 감염이 무증상의 자연 회복부터 간경변 혹은 간세포성 간암까지 다양하게 나타나는 요인들로 숙주의 요인과 바이러스의 요인으로 구분되어 제시되는데, 바이러스 요인으로는 감염된 바이러스이 유형이나 염기 변이들이 논의된다. HBV 유형을 구분하는 데는 혈청형과 유전자형이 이용되는데 근자에는 주로 유전자형이 이용된다. 이러한 HBV의 분포는 지역적으로 다르나 지역에 따라서 다른 유형들이 혼재되어 있다. 동남아시아는 B형이지만 극동아시아는 C형으로 알려져 있으며, 대만과 오키나와에서는 B와 C형이 혼재되어 나타난다. 이러한 결과로 미루어 보아 우리 나라의 남부지역에서는 B과 C형이 혼재되어 있을 가능성이 있다. 이에 본 연구는 제주 지역에서 HBV의 유전자형을 조사하고자 하였다. 대상과 방법: 원적지가 제주도이면사, HBsAg가 양성이었던 107명(평균 연령: 46.5세)을 대상으로 하였다. 이들의 혈청으로부터 HBsAg/antiHBe를 분석하고, DNA를 추출하여 7개의 유전자형에 따라 특이성을 갖는 시발체(genotype specific primer)들을 이용하여 PCR로 증폭한 후 이를 분석하였다. 주된 유전자형의 일부와 다른 유형에서 증폭에 이용되었던 시발체를 다르게 이용하여 hemi nested PCR로 증폭한 후 염기를 분석하여 계통발생학적 분석법을 이용하였다. 결과: 1. PCR에 의한 HBV DNA 양성은 107명 중 59명(55.1%)이 양성이었다. HBeAg/anti HBe의 발현 양태에 따라 음성/음성에서 2명(66.7%), 음성/양성에서 30명(41.1%), 양성/음성에서 24명(85.7%), 양성/양성에서는 3명(100%)에서 증폭되었다. 2. Multiplex PCR에서는 58명의 유전자형이 C형, 1명에서는 B형과 C형이 동반 출현하였다. 3. Genotype specific primer를 이용하여 각각 따로 PCR을 시행한 경우에 A형에 의하여 증폭된 예가 1예, B형에 의하여 증폭된 예가 1예, C형에 의하여 증폭된 예가 59예로 A형과 B형 모두가 C형에서 증폭된 예였다. 4. 한 쌍의 시발체에 의하여 증폭되었던 A형과 B형 및 C형의 일부에서 염기를 분석한 결과 모두 C 유전자형이었다. 결론: HBsAg이 양성인 제주 지역 주민의 HBV의 유전자형은 C형일 것으로 생각된다. Background/Aims: Hepatitis B virus (HBV) was classified into 8 genotypes by a sequence divergence in the entire genome designated from A o H. HBV genotypes have distinct geographic distributions. Recently, HBV genotypes have been partially found as influencing the clinical manifestation of chronic liver disease in hosts. In Korea, the distribution of HBV genotypes remains unclear. The aim of this study was to evaluate the prevalence of the HBV genotype on Jeju Island. Methods: Hepatitis B virus genotypes were evaluated among 107 hepatitis B carriers residing on Jeju Island. We used single PCR and multiplex-PCR assay with genotype-specific primer pairs for HBV genotypes A-F for the genotyping. Results: 1. Fifty nine samples (55%) were positive for HBV DNA. The positivity was different according to the pattern of HBeAg/anti-HBe expression, as -/-; 2/3 (66.7%), -/+; 30/73 (30%), +/-; 24/28 (85.7%) and +/+; 3/3 (100%). 2. In the single primer set of genotype-specific PCR, 59 samples (100%) were detected as genotype C and 2 (3%) were also detected as genotype A and B. 3. In multiplex-PCR, 58 samples (98%) were detected as genotype C and only one (2%) as a mixed pattern of genotype B and C. 4. When the PCR products were amplified with universal sense and genotype specific anti-sense from one genotype A, one B, and 2 C, all were included in genotype C. Conclusions: These results suggest that on Juju Island, almost all HBV genotypes are C.(Korean J Hepatol 2004;10:42-50)

In this thesis, the message transmission delay on a server system using HGCMP for group communication protocol was analyzed. The queue model of a server system was modeled by queueing theoretic approach. As the feedback structure was imbedded in the queue model, it is difficult to analyze the delay. To solve this problem, the simplification of the queue model was performed. After the simplification process, the queue model was modeled M/M/1. The transmission delay of a server system is calculated using average waiting time and service time in a server system.
