The purpose of this study was to determine the effects of music therapy on changes in the vital signs of patients about to undergo an operation. The patients listened to the music at a time when they were feeling preoperative anxiety up until the preanesthesia was given in the operating room. The subjects for this study were selected from sixty patients to undergo operations, who were hospitalized at Dong Eui hospital in Pusan city. They were assigned to two groups, thirty to the experimental group and thirty to the control group. The subjects were from 20 years old to 69 years old, and had no other problem except the one requiring the operation, and no premedication. The data were collected during the period from July 1 to September 30, 1993. The method used in this study was to measure state-anxiety on the ward in the morning of the operation, and vital signs immediately before leaving for the operating room. Vital signs were measured immediately before the anesthesia was given and after the experimental group had listened to the music during the ten minutes needed to prepare the operation setting. The control group just waited during ten mimutes. Vital signs were check again before the anesthesia was given. The data were analyzed by descriptive statistics, mean±SD, p-value, and t-test using the SPSS progrom. The results of this study are : 1. Systolic blood pressure taken in the operating room was elevated, over the level measured on the ward, by 5.00 ± 15.26㎜Hg in experimental group and 18.67±14.56㎜Hg in control group. (t=-3.5496, p=.0008) 2. Diastolic blood pressure was elevated by 6.67±12.95㎜Hg in experimental group and 18.67±12. 79㎜Hg in control group. (t=-3.6100, p=.0006) 3. Pulse was elevated by 2.931±9.44 / min in experimental group and 8.03±8.37 /min in control group. (t=-2.2144, p=.0307) 4. Respiration was elevated by 0.60±1.35 /min in experimental group and 1.57±1.48 /min in control group. (t=-2.6409, p=.0106) 5. Body temperature was down by 0.13±1.91'c in experimental group and elevated by 1.13±1.11'c in control group. (t=-3.1471, p=.0026) Thus, in this study there was a statistically significant difference in the change in the vital signs between the experimental group treated with music therapy and the control group which received no treatment. Because music therapy is valuable to decrease the anxiety of patients facing operations, the result of this study support its effect in relieving anxiety as a valuable nursing intervention. From this study, the following recommendations can be made : First, it is necessary to further study music therapy to develope a better system and determine optimal time. Second, it is necessary that more detailed re-search on measurement of changes in vital signs be done to determine changes over time intervals.

Purpose: Time of operation has been reduced and accuracy of operation has been improved since C-arm, which offer real-time image of patient, was introduced in operation room. However, because of the contamination of patient, C-arm could not be used more appropriately. Therefore, this study is to know factors of controlling exposure dose, image quality and the exposed dose of health professional in operation room. Materials and methods: Height of Wilson frame (bed for operation) was fixed at 130 cm. Then, Model 76-2 Phantom, which was set by assembling manual of Fluke Company, was set on the bed. Head/Spine Fluoroscopy AEC mode was set for exposure condition. According to detector size of C-arm, the absorbed dose per min was measured in the 7 steps OFD (cm) from 10 cm to 40 cm (10, 15, 20, 25, 30, 35, 40 cm). In each step of OFD, the absorbed dose per min of same diameter of collimation was measured. Moreover, using Nero MAX Model 8000, exposure dose per min was measured according to 3 step of distance from detector (20 cm, 60 cm, 100 cm). Finally, resolution was measured by CDRH Disc Phantom and magnification of each OFD was measured by aluminum stick bar. Result: According to detector size of C-arm, difference of absorbed dose shows that the dose of 20 cm OFD is 1.750 times higher than the dose of 40 cm OFD. It means that the C-arm, which has smaller size of detector, shows the bigger difference of absorbed dose per min (p<0.05). In the difference of absorbed dose in the same step of OFD (from 20 cm to 40 cm), the absorbed dose of 9 inch detect or C-arm was 1.370 times higher than 12 inch' s (p<0.05). When OFD was set to 20 cm OFD, the absorbed dose of non-collimation case was approximately 0.816 times lower than the absorbed dose of collimation cases (p<0.05). When the distance was 20 cm from detector, exposed does includes first-ray and scatter-ray. When the distance was 60 cm and 100 cm from detector, exposed does includes just scatter-ray. So, there was the 2.200 times difference of absorbed does. Finally, when OFD was increased, spatial resolution was 4 to 5 step was increased. However, low contrast resolution was not relative. Moreover, there was 1.363 times difference of magnification (p<0.05). Conclusion: When C-Arm is used, avoiding contamination of patient is more important factor than reducing exposed dose of health professional in operation room. Just controlling exposure time is just way to reduce the exposed does of workers. However, in the case, non-probability influence could be occurred. Therefore, this study proved that the exposed dose will be reduced if the factors such as using small detector size of C-arm, setting OFD from 20 cm to 25 cm and non-collimating. Moreover, dose management of C-arm in the non-interesting area will be considered additionally.

In orthopedics, hip arthroplasty is the operation that replaces damaged hip joint to artificial joint. In hip arthroplasty, quite better result can be achieved if robot is applied to machine cavity in bone, especially when cementless stem is used. So several kinds of robots were introduced for hip arthroplasty, but they used MRI, CT Scan, vision analysis and real time tracking of bone position for registration of robot. To overcome shortage of conventional robot surgery, gauge based registration method was proposed and small robot was designed. In this method, small robot is mounted on femur, and its position is determined by gauge registration method. Operation procedure was performed on model femur and result was analyzed. This robotic hip surgery system is expected to more adaptable in operation room.

The purpose of this paper is to describe the transition of a 1,100 beds teritary hospital from 50% softcopy operation to full PACS operation. For the past 2 years, radiologists and clinicians have been using PACS to provide softcopy services to the outpatient clinics and inpatient wards of orthopedics surgery, neurosurgery and neurology as well as emergency room, surgical intensive care unit, medical intensive unit, pediatrics intensive care unit and neonatal intensive care unit. The examinations requested by these departments account for about 50% of hospital's radiological exams. In September 1996, we began the second phase of PACS implementation and installed additional workstations (102) in the remaining wards and clinics, interfaced to PACS additional imaging modalites, and increased the capacity of both the image server (256 Gbytes) and optical juke boxes (3 Tbytes). As of January 1997, we are in the final phase of moving away from conventional film system to full PACS operation.
