This study aims to investigate the determinants of service quality and the relationships of service quality, customer satisfaction, word of mouth and subsequent purchase intention of medical service. SERVQUAL, an instrument developed by the marketing area, is offered as a possible measure of medical service quality. SERVQUAL measures service dimension of tangibles, reliability, responsiveness, assurance and empathy. The questionnaire method is used in this study. A survey is conducted on patients who are randomly selected. The questionnaire are sent to 300 patients and 208 are available. The objectives of this study were: 1) to find out the influence of determinants of service quality on medical service. 2) to investigate the relationship of medical service quality and customer satisfaction. 3) to analyze the relationship of customer satisfaction and favorable word of mouth, ubsequent purchase intention 4) to find out the gap perceived service quality between secondary and tertiary hospital. The results of this study are summarized as follows: 1) Reliability, responsiveness and assurance have a positive impact on the medical service quality. 2) Medical service quality has a positive impact on the customer satisfaction. 3) Customer satisfaction has a positive impact on the favorable word of mouth and subsequent purchase intention. 4) There is no gap between secondary and tertiary hospital of perceived service quality.

오늘날 교사 양성 질 관리 기제인 교원양성기관평가가 정착되면서 그 본질적 기능에 대한 의구심도 증폭되고 있다. 특히, 교사 공급 과잉이 발생하는 국가의 경우, 평가 자체의 적합성은 물론, 평가 결과의 활용이 예비교사 교육의 질 관리에 기여하지 못한다는 비판도 제기된다. 이러한 문제인식에서 본 연구는 중등교사가 과잉 공급되고 있는 한국과 중국의 사범대학을 대상으로 한 평가의 특징을 평가의 주체, 목적, 주기, 지표, 방법, 결과 활용이라는 여섯 가지 준거에 따라 비교분석할 목적으로 수행되었다. 주요 결과는 다음과 같다. 첫째, 한국과 중국의 사범대학 평가는 교원양성기관 교육 수준의 질 향상을 공식적 목적으로 표방하고 있지만 실제 평가 추진의 내용 및 결과 활용은 본질적 목적에서 벗어나 형식적으로 운영되고 있다는 공통적 문제가 발견되었다. 둘째, 평가 주체나 지표, 결과 활용 등에 있어서는 정부 주도의 관리 감독이나 양성 자원 통제 등에 치우쳐 있고 교사 직전교육의 질을 높이기 위한 사범대학의 질 제고는 뒷전이라는 상황은 교사 과잉 공급과 밀접하게 연관되어 있다는 점을 확인하였다. 이상 연구결과를 토대로 양 국가의 사범대학 평가가 본질을 회복하고 진정한 의미의 질 관리 기제로 개선되기 위해 필요한 정책적 제언을 제시하였다.

We present the results on the calibration of iso-center positions using the quality assurance system established at PMRC for determination of center position in X-ray and proton irradiation fields. Details on the system are presented in another presentation in this session. The equipment in the system is mounted on a patient treatment bed in each proton exposure room, G1 or G2. A center of a stainless ball on the equipment is set at a cross of laser markers located around the iso-center and fixed on the room and on the snout in the gantry. A proton beam or an X-ray beam is exposed onto the ball through a brass collimator of 100 mm ${\times}$ 100 mm and projected onto the imaging plate set at I cm behind the ball. On the axis perpendicular to the thrust axis of the gantry on the imaging plate, a distance between a center of the collimator image and a center of the ball image varies as a cosine function of gantry angles unless the ball is set on the iso-center. An amplitude of the cosine curve shows the distance between the ball and the iso-center, an offset the offset of the collimator, and a phase shift at a zero crossing point the ball direction viewed from the iso-center. We present the relation among the iso-center position, the laser maker position, and the center of proton and X-ray irradiation fields. Its stability and its reproducibility are discussed.

This paper aims to verify the clinical feasibility of a custom-made film created by a laser cutting tool for End-to-End (E2E) quality assurance in robotic intensity modulated radiation therapy system. The custom-made film was fabricated from the Gafchromic EBT3 film with the size of $8^{{\prime}{\prime}}{\times}10^{{\prime}{\prime}}$ using a drawing that is identical to the shape and scale of the original E2E film. The drawing was created by using a computer aided design program with the image file, which is obtained by scanning original E2E film. Beam delivery and evaluations were respectively performed with the original film and the custom-made film using fixed-cone collimator on three tracking modes: 6D skull (6DS), Xsight spine (XS), and Xsight lung (XL). The differences between total targeting errors of the original and custom-made films were recorded as 0.17 mm, 0.3 mm, and 0.17 mm at 6DS, XS, and XL tracking modes, respectively. This indicates that the custom-made film could yield nearly equivalent results to those of the original E2E film, given the uncertainties caused by distortions during film scanning and vibrations associated with film cutting. By confirming the clinical feasibility of a custom-made film for E2E testing, it can be expected that economic efficiency of the testing will increase accordingly.

For a maneuvering unmanned autonomous helicopter, it is necessary to design a proper controller of each flight mode. In this paper, overall helicopter dynamics is derived and hovering model is linearized and transformed into a state equation form. However, since it is difficult to obtain parameters of stability derivatives in the state equation directly, a linear control model is derived by time-domain parametric system identification method with real flight data of the model helicopter. Then, two different controllers - a linear feedback controller with proportional gains and a robust controller - are designed and their performance is compared. Both proposed controllers show outstanding results by computer simulation. These validated controllers can be used to autonomous flight controller of a real unmanned model helicopter.

일반적으로 원자력 관련 연구개발은 타 산업 및 사회에 미치는 파급효과가 크고, 참여 연구원 및 대중 안전에 대한 위험도가 높으며, 대규모의 투자비용이 요구되는 특성을 지니고 있다. 이러한 이유로 원자력 산업은 일찍이 품질보증 개념을 도입하여 원자력 시설의 안전한 이용을 도모하여 왔다. 최근에는 원자력 연구개발 분야에서도 연구결과의 신뢰도 확보 및 안전한 연구수행을 보장하기 위하여 품질보증 적용의 필요성이 강조되고 있다.(중략)

Recently there are increasing concerns on quality improvement activities related to difficult economic situations, more competitive environment, health professional's emphasis on quality, and customer's needs in health care. The purpose of this study was to identify educational needs in the quality improvement for staff nurses. Study setting was an acute care hospital having more than 1000 bed in Seoul, Korea. The subjects were 40 staff nurses who participated in the first Quality Assurance(QA) inservice education. Data were collected by self-administered questionnaire which consisted of four parts : QA knowledge and attitude(ten items, by five Likert scale), contents of QA education(ten items, by setting the priority), evaluation of the program(structure, time allocation, place, educational method), and general characteristics of respondents (age, duration to work for hospitals etc.) The response rate was 85%(34/40), Most had positive perspective and attitude about QI/QA activities, but 9% had negative impression and knowledge about this activities. Also they'd like to know the plan of hospital-level QI/QA activities, QI/QA current practice, general hospital system, the role of QA specialist and so on. Consequently, for building the quality improvement activities that is customer-focused, coordinated, outcome-oriented, resource-efficient, collaborative in Korea, at first the education about philosophy, theory, and implementation process of QI/QA should be conducted, and then that on QI/QA terminology, quality indicators development, the analysis and presentation of quality-related data and so forth be followed.
