Objectives: The purpose of this study was to evaluate the opinions of hospital managers on DRG pilot study. Methods: Managers of 800 hospitals which had participated in DRG pilot study during the period 1997-1999, were requested to respond to structured self-administerd questionnaire. The questionnaire was composed with six categories: the motivation and satisfaction for the DRG pilot study, the opinions on the level of unit price, the appropriateness of DRG classification, the change of medical service quality during the pilot study, the patient's complains resulted from DRG system. and the opinions on the nation-wide application of DRG system. Results : Of the 800 subjects, 327(clinic, 210: 25 hospitals, 82 general hospitals, and 16 tertiary hospitals) completed the questionnaire, and the overall response rate was 41%, 121 hospitals(27%) answered that they participated in DRG pilot study because of convenience of claims and 118 hospitals(35%) dissatisfied with DRG system. 251 hospitals(85%) thought that the level of unit price under the DRG system was same as or lower than that of fee-for service. 297 hospitals(92%) responded that DRG classification should be modified and 137 hospitals(47%) experienced deterioration of medical service quality during the DRG pilot study. The 116 hospitals(35%) experienced the patient's complains resulted from DRG system. The 85 hospitals(88%) didn't want nation-wide application of DRG system. Conclusion: Most of the responded managers seemed to have negative opinions on DRG pilot study, even though they had been participated voluntarily. Further studies and extensive evaluations of DRG reimbursement system are needed before nation-wide application.

This study sets a hypothesis on that the use of input control devices, which are similar to what we experience in real life, to control activities in games increases players' immersion rate, and compares general input control devices with dedicated input control devices in order to show appropriate results. Accordingly the process of the study is derived and the hypothesis is substantiated by understanding the relationship between game controlling activities and immersion rate. Overall satisfaction survey result on the use of dedicated devices shows that most players responded that they felt immersed enough in games when used dedicated devices and were highly satisfied. The use of the dedicated devices had positive impact on the increase of immersion rate in general. In order to increase immersion rate with controlling activities in games, the use of input control devices that are easy to handle and enable precise control is required, which shows that it will bring more fun and more increased immersion rate.

Objective : Clinical, radiographic, and outcomes assessments, focusing on complications, were performed in patients who underwent pedicle subtraction osteotomy (PSO) to assess correction effectiveness, fusion stability, procedural safety, neurological outcomes, complication rates, and overall patient outcomes. Methods : We analyzed data obtained from 13 consecutive PSO-treated patients presenting with fixed sagittal imbalances from 1999 to 2006. A single spine surgeon performed all operations. The median follow-up period was 73 months (range 41-114 months). Events during peri operative course and complications were closely monitored and carefully reviewed. Radiographs were obtained and measurements were done before surgery, immediately after surgery, and at the most recent follow-up examinations. Clinical outcomes were assessed using the Oswestry Disability Index and subjective satisfaction evaluation. Results : Following surgery, lumbar lordosis increased from $-14.1^{\circ}{\pm}20.5^{\circ}$ to $-46.3^{\circ}{\pm}12.8^{\circ}$ (p<0.0001). and the C7 plumb line improved from $115{\pm}43\;mm$ to $32{\pm}38\;mm$ (p<0.0001). There were 16 surgery-related complications in 8 patients; 3 intraoperative, 3 perioperative, and 10 late-onset postoperative. The prevalence of proximal junctional kyphosis (PJK) was 23% (3 of 13 patients). However, clinical outcomes were not adversely affected by PJK. Intraoperative blood loss averaged 2,984 mL. The C7 plumb line values and postoperative complications were closely correlated with clinical results. Conclusion : Intraoperative or postoperative complications are relatively common following PSO. Most late-onset complications in PSO patients were related to PJK and instrumentation failure. Correcting the C7 plumb line value with minimal operative complications seemed to lead to better clinical results.

For many years, engineers in the field of acoustics have used the A-weighted sound pressure level (SPL). Since they were interested just in a reduction of noise, the A-weighted SPL was considered good enough to quantify noise problems. This is reasonable because loudness is usually the most important parameter for most noise problems and A-weighted SPL is often reasonably well correlated with loudness. As the overall noise levels drop, however, other parameters become more important and must be considered, Advent of sound quality came from an understanding that A-weighted SPL only reflects the loudness of a sound. It is obviously impossible to characterize a complex sound with a single number. Although product mostly has revealed physical quantities created by the standpoint of engineers, consumers perceive and evaluate products on the non-physical characteristics, such as feelings, emotions, and experiences in different social and cultural situations. Especially, for the household appliances for instance air-conditioner or refrigerator, the sound is heavily related to the satisfaction of a customer who is a real user of the product and is very important factor to decide purchasing as well as visual design. Therefore, in this research, the general tendency of consumer's psychology was investigated for the appliances. And also, in order to obtain clear guidelines fur sound manipulation, the characteristics of the sound of air-conditioning systems and refrigerators were compared with competitors'. since it is important to overcome the discrepancy between engineering and marketing, the relevance of sound manipulation must be documented from the consumer's perspective. That is the reason why we conducted a consumer and marketing oriented study.
