The purpose of this study is to reveal how the road traffic noise influences on the response of teachers and students, which composed of conversation, studying, relation, and physical disturbances. The research method used in this study was self- administrated questionnaire. Samples of the survey were composed of 420 persons(l14 teachers and 306 students) who are exposed to traffic noise less than 65 dB(A) from two junior high schools and 410 persons(140 teachers and 270 students) from two noisy junior high schools which the road traffic noise above 65 dB(A). In the response of both of the teachers and students in noisy(above 65 dB) schools complaints of disturbances of conversation, studying, relaxation, and physical disturbances are much higher than that of less noisy schools' teachers and students(p<0.01 ). On the occasion of time and season, the subjects answered the traffic noise cause high troublesome and stresses in the afternoon(12:00-17:00) and summer respectively. It is necessary to provide governmental comprehensive and fundamental measures to improve the noisy school environments.

Aortic regurgitation is a common valvular heart disease, usually the result of rheumatic fever, or syphilis, and rarely of congenital origin. It is frequently associated with other valvular heart disease, especially mitral valve disease. It can be diagnosed by the presence of pulse pressure widening, a Corrigan pulse, and an early decreascendo diastolic murmur at the left sternal border between the second and third intercostal spaces. After the clinical application of cineaortography in the diagnosis of valvular disease, Segal et al (1964) first reported rheumatic aortic regurgitation without an audible murmur in patients having mitral valve disease. The importance of discovering aortic reguritation in patients with predominent mitral disease has begun to be appreciated recently, especially as commisurotomies for the relief of mitral stenosis are performed more frequently. Nowadays eventhough the severity of aortic regurgitation is often not evident preoperatively, aortic regurgitation can become very evident when mitral stenosis is relieved. This study was comprised of seventeen patients with silent aortic regurgitation which was confirmed by cineaortography at Severance Hospital from January, 1970 to August, 1976. 1. Of the seventeen patients, 12 patients were associated with mitral stenosis, 4 with mitral steno-insufficiency, and 1 with mitral insufficiency. 2. Silent aortic regurgitation was suggested from the accompanying clinical features such as chest pain, apical heaving, and left ventficular hypertrophy pattern on both roentgenogram of the chest and electrocardiogram. 3. The severity of the aortic regurgitation was mild to moderate; 7 of the 17 patients being grade I, and 10 patients being grade II on cineaortogram.

This study was aimed to assess the free calcium status with or without its direct measurement in patients on hemodialysis(HD: n=27) and malnourished ones from extrarenal diseases(MN: n=14). It was performed by the comparison of measured free calcium (Ca++m) levels by gas analyzer and calculated free calcium(Ca++c) levels based on those of total calcium (TCa), albumin, and pH with the modified algorithm invented by Moore(J Clin Invest. 49:318, 1970). Of 27 HD pts, 14(5296) had low[Ca++m] below 1.05mmol/L despite only 2(796) with low [TCa] below 2.05mmoV L, whereas 14 MN pts had similar numbers between low[Ca++m] and low[TCa]. Compared to MN pts, HD pts showed significantly lower mean levels(SE) of pH(7.37 0.01 vs. 7A4 0.01, p<0.01), higher[TCa](2.33 0.04 vs. 1.83 0.08mmol/L, p<0.01), and higher albumin (4.33 0.06 vs. 2.59 0.17mg/dL, p<0.01).However, [Ca++m] between 2 groups did not reveal any significant difference. Furtherrnore, in total 41 pts of 2 groups, no similarity was observed between the values of [Ca++ml and [Ca++c] but with their significant difference(p<0.05). Only[TCa] was significantly corre- lated with albumin level(r=0.73, p<0.01). Furthermore, multiple regression analysis between [Ca++m] and other factors including pH and albumin didn't show any correlation. In conclusion, this data suggests that relatively high prevalence of low values of physiologically important free ionized calcium in chronically ill pts, especially on maintenance HD, could be missed when predicted on total calcium level, and pH without its direct measurement.

OBJECTIVES: To determine if hysterectomy with or without ovarian preservation is asso-ciated with obesity in premenopausal women. METHODS: 581 women for routine check up from Jan. 1985 to Dec. 1995 in the depart-m ent of Gynecology at Korea Veterans Hospital were included. The obesity was evaluated by BMI(body mass index) scores. 80% of hysterectomy were confirmed from the hospital records. The age, weight, height, blood pressure, menstr- ual history, history of DM and hypertension, social history of alcohol and smoking and other cardiovascular risk factors such as cholesterol, HDL-cholesterol, triglycerides were checked. The 248 women with natural postmenopausal status before hysterectomy, taking hormonal replacement therapy after hysterectomy and having performed hysterectomy due to malign- ancy were excluded. RESULTS: All women performed hysterectomy were in premenopausal status in this study. Therefore, the final numbers of subjects included in the analysis was 333. Hysterectomy wit- hout ovarian preservation were performed in 58 cases and hysterectomy with ovarian pres- ervation were in 57 cases. The 218 premenopausal cases which did not performed hystere- ctomy were considered control group. BMI scores were higher in cases without ovarian pres- ervation than with ovarian preservation. And BMI score was associated with the postoper- ative duration in hysterectomy with ovarian preservation. CONCLUSIONS: We suggest that hysterectomy without ovarian preservation in premeno- paussal women were associated with increased obesity, especially BMI scores.

BACKGROUND: Caudal block is useful when anesthesia for surgery or treatment for chronic pain is needed, but this procedure has a failure rate of up to 25% even when it performed byan experienced physician. This high failure rate is usually due to improper needle placement. METHODS: After gaining approval of the ethics committee, 46 patients received caudal blocks under ultrasound guidance; these were performed after the anatomical structures in the sacral hiatus had been measured with ultrasound. All these procedures were performed by the same anesthesiologist. The position and direction of the needle were identified using fluoroscopy by injecting a radio-opaque contrast through the needle. The time taken from thelidocaine injection to verification of the needle was measured and the planned nerve block was then carried out. RESULTS: All cases of needle insertion into the sacral canal under ultrasound guidance were successful. The average duration of the procedure and the trial count were 134.1 +/- 10.1 seconds and 1.2 +/- 0.1, respectively. In 12 of the 46 cases (26%), the needle deviated either left or right in the sacral canal, so the direction of the needle had to be adjusted. The distance between two cornua, the depth of the sacral hiatus and the thickness and length of the sacrococcygeal ligament were 17.1 +/- 0.4, 3.9 +/- 0.3, 2.3 +/- 0.1 and 24.9 +/- 0.9 mm, respectively. CONCLUSIONS: Ultrasound guidance can increase the success rate of inserting a needle into the sacral canal. However, even when ultrasound is used, the needle can deviate either left or right in the sacral canal.

PURPOSE: To evaluate MR characteristics of periosteal reactions and subperiosteal abscesses in osteomyelitis as compared with radiographs. MATERIALS AND METHODS: We retrospectively reviewed 28 patients(18 males, 10 females) with osteomyelitis. Nineteen patients underwent MR imaging with 0.5 T. We analyzed for morphologic patterns, intervals of appearance and disappearance of periosteal reactions after symptom onset. Twenty-three patients were confirmed by surgery and 5 patients by the radiologic findings, clinical and laboratory data. RESULTS: Periosteal reaction appeared as low signal intensity arc on the T1- and T2-weighted axial images. In 3-7 days after symptom onset, periosteal reactions and subperiosteal abscesses were noted on MR imaging, and only two of eleven patients were noted in radiographs. Periosteal reactions of 8-14 days after symptom onset were demonstrated in all of 13 patient on MR, and 9 on plain radiographs. All patients with 2 weeks after symptom onset showed perioste.al reaction in plain film and MR. The periosteal reactions persisted until approximately 2 to 3 months after treatment on follow up radiographs. CONCLUSION: Periosteal reactions in osteomyelitis are detected on the MR imaging earlier than plain film. MR is valuable in detecting subperiosteal abscess which is not appecent in simple radiographs. Periosteal reactions can be seen on MR in 3 days after symptom onset and persist for 2-3 months after treatment.
