기계경비시스템이 제공하는 서비스에는 유 무형의 서비스가 모두 포함되어 그에 대한 품질 평가가 쉽지 않은 것이 사실이다. 그럼에도 불구하고 본 연구는 서브퀼 모형을 도입하여 기계경비시스템의 서비스품질 구성차원을 확인하고, 서비스품질과 고객만족과의 관계를 실증적으로 검증하고자 하였다. 이를 위하여 대구지역에서 기계경비서비스를 이용하고 있는 소규모 상점을 대상으로 경험적 연구를 진행하였으며 연구결과와 시사점은 다음과 같다. 첫째, 서비스품질을 구성하는 요인들이 고객만족에 영향을 주는지 검증한 결과, 서비스품질의 4가지 구성요소는 모두 고객만족에 유의미한 영향을 미치는 것으로 나타났다. 또한 그 영향력의 크기는 공감성, 확신 신뢰성, 응답성, 유형성의 순서로 확인되었다. 따라서 회사가 제공하는 최신식 설비 장비도 중요하지만 그보다는 고객에 대한 배려와 개별적 관심 및 신뢰성과 확신성을 심어줄 수 있는 직원들의 능력이 더욱 중요함을 알 수 있었다. 둘째, 서브퀼 모형을 도입하여 기계경비시스템의 서비스품질을 측정하고자 하였으나 요인 분석결과 서비스품질을 구성하는 차원은 확신 신뢰성, 공감성, 유형성, 응답성 4가지로 확인되었다. 따라서 향후의 연구에서는 확신성과 신뢰성의 개념을 보다 명확히 구분하는 한편, 국내 기계경비업체의 서비스품질 평가에 보다 적합한 모형으로의 개발을 고려해보아야 할 것이다.

This research examines the possibilities of a traditional costume revival and digital exhibition as well as the application of 3D virtual clothing modeling data in order to preserve and record a disappearing costume heritage to realize it as a social education tool through the newly emerging technology of 3D virtual clothing. A 3D revival of costumes worn by royal families and aristocrats was accomplished through the 3D animation and simulation technology of Maya 2011 (Autodesk, Inc.) and Qualoth (FX Gear, Inc.). The simulation shows the possibility of a 3D revival and digital exhibition of costume heritage. However, further technology support to analyze and realize the composition and design is still necessary to develop the digital contents of traditional garment culture that includes skirt pleats, petticoat silhouettes, that exaggerates the skirts and knots of traditional upper garments (Jeogori). Further studies on design attributes of historic costumes and the upgrading of 3D simulation software are required to realize 3D virtual clothing. Korean traditional costumes will be revived as a cultural content in the digital era as a result of outstanding issues detected by this study.

Minimizing the cylinder wear and the consumption rate of cylinder oil in a large two-stroke diesel engine is of great economic importance. A motor-driven cylinder lubricator for Sulzer RT-flex large two-stroke diesel engines developed by authors is in need of mounting a quill system to lubricate cylinder parts for smoother operation. In order to apply the common-rail lubricating system to the developed cylinder lubricator as the second research stage, the quill system with a progressively quantitative distributor is improved in the electronically controlled quill system with an accumulating distributor. In this study, the effects of lubricator motor speed, plunger stroke and cylinder back pressure on oil feed rate, maximum discharge and delivery pressures are experimentally investigated by using the electronically controlled quill system with an accumulating distributor in the developed cylinder lubricator. It is found that the oil feed rate of the electronically controlled quill system with an accumulating distributor is larger than that of the quill system with a progressively quantitative distributor because of the increase of delivery speed and volume by changing the location of accumulator in the same experimental condition.

Minimizing the cylinder wear and the consumption rate of cylinder oil in a large two-stroke diesel engine is of great economic importance. A motor-driven cylinder lubricator for Sulzer RT-flex large two-stroke diesel engines developed by authors is in need of mounting a quill system to lubricate cylinder parts for a smooth operation. In order to apply the common-rail lubricating system to the developed cylinder lubricator as the second research stage, the mechanical quill system with a progressively quantitative distributor (M.D.S.) is improved in the electronically controlled quill system with an accumulating distributor (E.D.S.). In this study, the effects of lubricator motor speed, plunger stroke and cylinder back pressure on oil feed rate and inequality rate are experimentally investigated by applying E.D.S. to the developed cylinder lubricator. It is found that the oil feed rate of E.D.S. is higher than that of M.D.S. because of the increase of delivery speed and volume by changing the role of accumulator in the same experimental condition. It can be also shown that, in E.D.S., the inequality rate is decreased a little or hardly unchanged as the cylinder back pressure and plunger stroke is elevated, while the inequality rate increased in M.D.S.. The inequality rates of E.D.S. and M.D.S. are lowered as the lubricator motor speed is increased.

Minimizing the cylinder wear and the consumption rate of cylinder oil in a large two-stroke marine diesel engine is of great economic importance. In Korea, authors first developed a motor-driven cylinder lubricator for a Wartsila Switzerland large two-stroke diesel engine. The characteristic of the developed product is that can control automatically the oil feed rate with a load fluctuation by the motor drive and the offset cam. For manufacturing the reliable and useful products, however, it is necessary to investigate further characteristics and to improve performances as a cylinder lubricator. In this study, the effects of pump motor speed, plunger stroke and cylinder back pressure on oil feed rate, maximum discharge and delivery pressures are experimentally investigated by using the electronically controlled quill injection system and distributer in the developed cylinder lubricator. It is found that the oil feed rates of electronic control and mechanical type quills with the in-cylinder back pressure are differently characterized by the role of accumulator, the viscous resistance of contact area, etc. It can be also shown that the maximum discharge pressure of the electronic control quill is lower than the mechanical type one but the maximum discharge pressure difference of two types decreased as plunger stroke is small, and the maximum delivery pressures of two types increased as plunger stroke, motor speed and back pressure are elevated but the maximum delivery pressure of mechanical type is higher than the one of electronic control type.

Minimizing the cylinder wear and the consumption rate of cylinder oil in a large two-stroke marine diesel engine is of great economic importance. In Korea, a motor-driven cylinder lubricator for a large two-stroke marine diesel engine manufactured by $W{\ddot{a}}rtsil{\ddot{a}}$ Switzerland Co., Ltd. was first developed by authors through the joint research of industry-university in 2002. The characteristic of the developed product is that can control automatically the oil feed rate to a load fluctuation by the motor drive and the offset cam. The performance of the product is not also inferior to the conventional one. For manufacturing the reliable and useful products, however, it is necessary to investigate further characteristics and improve the performance of a cylinder lubricator. In this study, the effect of quill with and without accumulator on maximum discharge pressure, delivery delay duration and oil feed rate relative to motor revolution speed using plunger stroke as a parameter is experimentally investigated by using the developed cylinder lubricator. It is found that the maximum discharge pressure with accumulator is higher than that of no accumulator as plunger stroke and motor revolution speed are elevated, and the delivery delay duration with accumulator is shorter than that of no accumulator as plunger stroke and motor revolution speed are increased. Also, oil feed rate with accumulator is less than that of no accumulator except for a plunger stroke of 2 mm as plunger stroke and motor revolution speed are raised.

One of the problems in grinding process using a machining center(MC) with a small diametric wheels is machining error due to decrease of the quill diameter. In this study, side-cut grinding is performed with a vitrified bonded CBN wheel on the machining center. Grinding experiments are performed at various grinding conditions including quill length, quill diameter and depth of cut. The effect on the grinding force, machining error and surface roughness due to the change of the quill rigidity are investigated experimentally. The slenderness ratio of the quill is significant factor to analyse the change of the grinding force and machining error.

This study was attempted to investigate the possibilities of fitness evaluation of virtual model using 3D clothes modeling software. For the purpose, two one-piece dresses were made with two kinds of patterns using Qualoth program, and then each dress was fitted to a real model and a virtual model, and the results were compared and discussed. The result of this study was as follows. First, the fitness evaluation of real model showed a significant difference only at a little difference in figures (1-2.5cm) of the pattern, while any significant difference in appearance was not found in case of a virtual model fitted a dress made out of a pattern with the same difference in figures. Second, items to evaluate a difference in patterns using 3D clothes modeling software were shoulder line, the distance between shoulder points, armhole line, ease of armscye depth, and overall appearance. Because all the items fall under design lines which make up outer lines of a cloth, it can be said that the Qualoth program is good for representing design, rather than exposing a small difference in patterns.
