Sinomenium acutum has been used for the treatment of rheumatoid arthritis, arrhythmia, and pain. We evaluated the quality of S. acutum extract by quantitatively analyzing its components such as sinomenine, magnoflorine and syringaresinol with the simultaneous determination method using HPLC-DAD. A total of 53 samples collected from different localities were evaluated with this quality evaluation method. Sinomenine, magnoflorine and syringaresinol from tested samples ranged from 0.0649~9.1050%, 0.7460~10.7590% and 0.0010~0.2441%, respectively. In the current study, we were able to exhibit the diverse quality of S. acutum samples collected from various locations using the simultaneous determination method.

With the rapid development of communication technology and widespread uses of internet service, utilization of internet-based medical information systems which transmitts moving pictures of medical objects is becoming a common practice. The internet-based medical information service prvovides richer information than conventional services such as touch-tone telephone, personal computers e-mails, or pagers, because "a picture is worth a thousand words". However, the systems passively transmits moving pictures of the medical objects to the users, and thus the system cannot intelligently adjust itself to provide better service. As the tradeoff exists between transmission speed and quality of the image, there is a need that moving pictures be analyzed to adjust the trnasmission speed and image quality. When very little difference between consecutive images are detected, the system can automatically increase the size of the image files, thus enhancing the quality of image. In contrast, the system should increase the number of images to send more pictorial information by sacrificing the quality of each individual image, when a significant difference is detected. In this paper an adaptive filtering technique is introduced which adjusts the quality of image and transmission speed according to a clinical situation in hospital.

The purpose of this study is to identify which factors of medical service quality were considered important by patients based on survey on eight hospitals located in Seoul. We analyzed the difference in impact of health service quality factors between the two groups with short and long inpatient days. In addition, we analyzed which service factors affected the customer satisfaction more differently across the inpatient groups. We found that patient satisfaction was not different between the two groups with short and long inpatient days. But the two groups showed different priority orders of medical service factors that affect patient satisfaction. In the group with long inpatient days, the order of medical service factors are cleanness, speciality, process. In the group with short stay, important factors are speciality, cleanness and convenience of facilities. These findings imply that hospitals should set up different marketing strategies across the different inpatients groups.

In the field of medical diagnostics, interested parties have resorted increasingly to medical imaging. It is well established that the accuracy and completeness of diagnosis are initially connected with the image quality, but the quality of the image is itself dependent on a number of factors including primarily the processing that an image must undergo to enhance its quality. This paper introduces an algorithm for medical image compression based on the quincunx wavelets coupled with SPIHT coding algorithm, of which we applied the lattice structure to improve the wavelet transform shortcomings. In order to enhance the compression by our algorithm, we have compared the results obtained with those of other methods containing wavelet transforms. For this reason, we evaluated two parameters known for their calculation speed. The first parameter is the PSNR; the second is MSSIM (structural similarity) to measure the quality of compressed image. The results are very satisfactory regarding compression ratio, and the computation time and quality of the compressed image compared to those of traditional methods.

Objective : To empirically investigate the relationship of internal and external customer satisfactions, service quality, and customer loyalty in medical services. Methods : This essay proposes an integrated model to explain the causality of internal and external customer satisfactions, service quality, and customer loyalty. To this end, a structural model was developed, consisting of the following factors: internal and external customer satisfactions, service quality, and customer loyalty. The study included 214 sets of data, with 107 sets being collected for both out-patients and in-patients. The data were analyzed using AMOS 4.0. Results : We found the greater the internal customer satisfaction, the greater the out-patient quality of service quality. Secondly, the greater the service quality, the greater the external customer satisfaction of both in- and out-patients. The service quality of doctors, compared to that of the nurses, had a greater effect on external customer satisfaction. Thirdly, the service quality of doctors and nurses affected both internal and external customer satisfactions, which ultimately affected the customer loyalty. Finally the greater the external customer satisfaction, the greater the customer loyalty. Conclusion : This Study confirms the positive relationship among the internal and external customer satisfactions, service quality, and customer loyalty, which proves the doctors quality of service is the primary factor for external satisfaction, and customer loyalty relating to medical services.

The purpose of this study is to examine the effect of the medical service quality of the nursing hospital on the inpatients' satisfaction, reuse intention and to verify the mediating effect of the inpatients' satisfaction. The subjects of this study were 255 male and female inpatients in Hiroshima in Japan. The collected data were used as a model of path coefficients obtained through analysis of covariance structure and hypothesis test. As a result of verification, level of medical team and medical service, reception, facility and fee of the medical service quality of the nursing hospital perceived by the inpatients showed a statistically significant positive correlation with the inpatients' satisfaction. The inpatients' satisfaction showed a statistically significant positive correlation with their reuse intention. The level of medical team and medical service, reception, facility and fee of the medical service quality of the nursing hospital perceived by the inpatients shows a statistically no significant positive correlation with the reuse intention. But, they show a statistically significant positive correlation with the reuse intention with the mediating effect of the inpatients' satisfaction. Finally, the result of this study is to confirm the effect of the medical service quality on the inpatients' satisfaction, reuse intention of the nursing hospital. In this process, it is meaningful to verify the role and function of medical service quality of the nursing hospital.

The machine log files recorded by a scanning control unit in proton beam therapy system have been studied to be used as a quality assurance method of scanning beam deliveries. The accuracy of the data in the log files have been evaluated with a standard calibration beam scan pattern. The proton beam scan pattern has been delivered on a gafchromic film located at the isocenter plane of the proton beam treatment nozzle and found to agree within ${\pm}1.0mm$. The machine data accumulated for the scanning beam proton therapy of five different cases have been analyzed using a statistical method to estimate any systematic error in the data. The high-precision scanning beam log files in line scanning proton therapy system have been validated to be used for off-line scanning beam monitoring and thus as a patient-specific quality assurance method. The use of the machine log files for patient-specific quality assurance would simplify the quality assurance procedure with accurate scanning beam data.
