Most of existing wind turbine system is used with geared type; however, this type has lots of problems which are noisy, weight, maintenance and so on. In this paper, wind turbine system with fluid torque converter applied to solve these problems. In case of the proposed wind turbine system, it is possible to transmit torque to adaptable distance. So various sets including generator, inverter and auxiliary motor move from the nacelle to the ground. As a result, Total weight in Nacelle can be decreased. however, the efficiency can be decreased with fluid tourque system.. We also applied auxiliary motor to fluid touque system . So, we also realized rated revolutions and rated output windturbine and could get considerable good data.

To ensure the reproducibility of the dyeing of cotton knit by cold pad batch(CPB), the solubility, alkali stability and substantivity of multi functional type reactive dyes were tested. The color difference of the cotton knit CPB dyeing products between laboratory and dye house was measured. The results showed that the equipments, dyes and fabrics, all of them influenced the color differences of the final samples between the laboratory and dye house. These factors could not be controlled to reduce the color difference between the laboratory and dye house in the conventional computer color matching algorithm. A new color match prediction method based on the non-negative matrix factorization(NNMF) algorithm was introduced and the applicability was studied by comparing with the conventional color match prediction method based on the Newton-Lapson algorithm. The color match prediction method based on the NNMF showed more accurate recipe prediction results than the conventional color matching method for the CPB dyeing process of cotton knit fabric.

이 연구는 경호업무수행 향상을 위하여 민간 경호원들의 체력의 실태를 분석으로써, 전공무도별 체력 요인에 따라 어떠한 차이가 있는지를 규명하는데 그 목적이 있다. 따라서 경호원 남자 80명을 대상으로 8개 항목의 체력검사를 실시하여 다음과 같은 결론을 얻었다. 첫째, 유도전공 경호원에게 영향을 미치는 체력요인은 근력(배근력), 유연성(윗몸앞으로 굽히기), 근지구력(윗몸일으키기), 전신지구력(2000m달리기)요인으로 나타났다. 둘째, 태권도전공 경호원에게 영향을 미치는 체력요인은 근지구력(윗몸일으키기), 근력(악력), 평행성(눈감고 외발서기)요인으로 나타났다. 셋째, 합기도전공 경호원에게 영향을 미치는 체력요인은 근지구력(윗몸일으키기), 평행성(눈감고 외발서기), 순발력(제자리 멀리띄기)요인으로 나타났다. 넷째, 검도전공 경호원에게 영향을 미치는 체력요인은 순발력(제자리 멀리띄기), 근력(배근력), 전신지구력(2000m달리기), 민첩성(10m왕복달리기)요인으로 나타났다. The purpose of this study is to investigate the physical strength factor of secret servicemen. In order to achieve that purpose, physical measurement(8 items related to fitness) was conducted to secret servicemen engaging in private security companies, which is analyzed by factor analysis. The results of this study were as follow; First, the factor affecting the performance of secret servicemen related to Power, Flexibility, Muscular Endurance and Whole body Endurance was remarkable to the subjects majoring Judo. Second, the factor affecting the performance of secret servicemen related to Muscular Endurance, Strength and Balance was remarkable to the subjects majoring Taekwondo. Third, the factor affecting the performance of secret servicemen related to Muscular Endurance, Balance and Power was remarkable to the subjects majoring Hapkido. Fourth, the factor affecting the performance of secret servicemen related to Power, Muscular Endurance and Agility was remarkable to the subjects majorin Gumdo.
