BACKGROUND: Most surgical patients experience preoperative anxiety. This anxiety can effect the amount of preanesthetic medication and anesthetic agents needed, and contribute to postoperative pain. Music has been recognized as a way to reduce anxiety and fear. The effect of hymn and sutra-chanting on the preanesthetic patient's anxiety in the operating room were studied. METHODS: 98 patients were divided into two groups according to the religionist or atheism. Group I(n=50, religionist) and Group II(n=48, atheism) listened to hymn or sutra-chanting according to the patient's religion and choice. At ward, hemodynamic variables including systolic and diastolic blood pressure and pulse rate were measured as control values. Hemodynamic variables and measurements of anxiety score with Hamilton anxiety rating scale were made at pre-music and post-music in the operating room. Also, patient's response to the music was measured on the postoperative 5-6th day. RESULTS: There were no difference between ward, pre-music, and post-music in terms of systolic pressure, diastolic pressure and pulse rate except the systolic pressure at pre-music that is grater than that of controls in both groups. Both group, anxiety score at post-music was significantly lower than that of pre-music (10.2+/-3.4 vs 4.4+/-2.9, 11.0+/-3.2 vs 5.7+/-3.1). At post-music, anxiety score in Group I showed significant reduced compaired with Group II (p<0.05). Patients showed relatively good satisfaction with music in both groups. CONCLUSION: The results suggest that music with hymn and Sutra-chanting were effective to reduce preanesthetic anxiety in both religionist group and atheism group.

The authors examined 312 outpatients, including 100 with otorrhea, 144 with rhinorrhea and 68 with pharyngeal discharge. The pH of otorrhea was generally acid, except in 2 cases of diffuse otitis externa where the discharge was strongly alkalihe. Otorrhea in purulent otitis media was mucopurulent or purulent and was strongly acid. The pH of rhinorrhea ranged from 6.6 to 7.4, being generally weakly alkaline. In acute rhinitis, it was alkaline in half the cases; a tendency to greater alkalinity showed in cases of marked swelling of the inferior nasal conchae. In chronic paranasal sinusitis, the pH generally shifted to the acid side; in acute paranasal sinusitis and in nasal polyps, it was weakly alkaline in all cases; and in allergic rhinitis it was neutral with in a narrow range. the usual pH of oral and pharyngeal discharges ranged from 6.4 to 7.0, being generally weakly alkaline. The character of inflammatory discharges was serous or mucous in all cases, except for a case of peritonsillar abscess with mucopurulent discharge; the pH was weakly alkaline in 5 cases (7.4 per cent), neutral in 26 (38.2 per cent), and acid in 37 (54.4 per cent). When these discharges changed in character from seromucous to purulent, their pH was lowered.

This study was designed to investigate factors relating to fiscal deficit for regional health insurance. The financial statements for the fiscal year 1990 of nationwide 254 regional medical insurance societies were analyzed. Important findings are summarized below: 1. There were differences in the main reason for the financial deficit among regions when deficit and surplus societies were compared by regions. The total revenue per enrollee, especially revenue from the premium contribution of a deficit society was significantly smaller than that of a surplus society in large cities and counties. On the other hand, the total expenditure per enrollee of a deficit society was larger than that of a surplus society in small cities. 2. Both low premium irate at the beginning of health insurance program and less effort to increase the premium rate were main factors for the smaller revenue from the contribution of a deficit society in large cities and counties. 3. Larger expenditures per covered person of a deficit society in small cities were explained with larger medical expenditures especially for out-patients services rather than larger administrative expenses. 4. A regression analysis showed that utilization rates in out-patient services were significantly associated with income and numbers of total medical care institution per capita within a region where a health insurance society located. Also expenses paid by insurer per visit were associated with the proportion of utilization for tertiary care hospitals as well as the proportion of utilization of public health centers.

PURPOSE: In order to obtain basic data for treatment plan in radiosurgery, we measured small fields of 6 MV X-rays and compared the measured data with our Monte Carlo simulations for the small fields. MATERIALS AND METHODS: The small fields of 1.0, 2.0 and 3.0 cm in diameter were used in this study. Percentage depth dose (PDD) and beam profiles of those fields were measured and calculated. A small semiconductor detector, water phantoms, and a remote control system were used for the measurement. Monte Carlo simulations were performed using the EGS4 code with the input data prepared for the energy distribution of 6 MV X-rays, beam divergence, circular fields and the geometry of the water phantoms. RESULTS: In the case of PDD values, the calculated values were lower than the measured values for all fields and depths, with the differences being 0.3 to 5.7% at the depths of 2.0 to 20.0 cm and 0.0 to 8.9% at the surface regions. As a result of the analysis of beam profiles for all field sizes at a depth of 10cm in water phantom, the measured 90% dose widths were in good agreement with the calculated values, however, the calculated penumbra radii were 0.1 cm shorter than measured values. CONCLUSION: The measured PDDs and beam profiles agreement with the Monte Carlo calculations approximately. However, it is different when it comes to calculations in the area of phantom surface and penumbra because the Monte Carlo calculations were performed under the simplified geometries. Therefore, we have to study how to include the actual geometries and more precise data for the field area in Monte Carlo calculations. The Monte Carlo calculations will be used as a useful tool for the very complicated conditions in measurement and verification.

PURPOSE: The dose calculation program for the Buchler type remote afterloading system was developed. This program also can be used to calculate dose for various sealed sources. METHODS AND MATERIALS: We determined the source length and distribution by dividing the program disk to 72 points. The dose rate for the each program disk and source was calculated. The dose rate table for the xy coordinate was established. The dose rate for the interesting points of the patient were calculated by using this table. We also made isodose curve from this calculations. RESULTS: The storage size for the dose rate table were increased.But the calculation of the dose rate for the patient were carried out rapidly. So we could get real time calculation. CONCLUSION: By using this program, we could calculate the dose rate for the various oints of the patient quickly and accurately. This program will be useful for the treatment with various linear sources.

Korean Circulation Journal 2002;32(7):588-595
BACKGROUND AND OBJECTIVES: This study was performed to assess the morbidity and mortality of 311 patients implanted with at least one Omniscience prosthetic valve between January 1992 and January 2000. SUBJECTS AND METHODS: Following valve implantation all patients were followed up with routine interviews, physical examination and echocardiography. RESULTS: The mean follow-up duration was 5.8+/-0.9 (standard error, SE) years with a mean follow-up interval of 8.5+/-0.7 (SE) months. The 311 patients received the following type (s) of valve: mitral, aortic, both or tricuspid valve, in 166 (47.9%), 99 (32.0%), 44 (19.5%) and 2 (0.6%) of cases, respectively. The cumulative follow up was 1143.4 patient-years (pt-yr). Death occurred in eight patients (0.7%/ pt-yr at linearized rate), and redo-operations were required in 27 patients (2.4%/pt-yr) due to valve failure. Actuarial freedom from all complication was 72.5%+/-8.2% (SE). Freedom from pannus formation, paravalvular leak, or thromboembolism plus anticoagulant related bleeding were 83.1%+/-3.5% (MVR/AVR 92.7%+/-4.7%/73.4%+/-2.8%), 95.2%+/-2.1% (MVR/AVR 96.8%+/-4.2%/93.6%+/-3.2%), and 96.1%+/-2.5% (MVR/AVR 95.6%+/-5.6%/96.7%+/-4.7%) respectively. CONCLUSION: Our results with this prosthesis demonstrate relatively high incidences of valve related complication especially due to pannus formations and paravalvular leaks. We could reduce the incidences of mortality by earlier detection of complications, redo-operations and routine checks.
