A cross-sectional study was conducted to investigate the effect of long term noise exposure on blood pressure among steel mill workers. The workers participated in periodic medical examinations performed from August 27 to September 6 in 1990. Examined were 1,034 workers with high-level noise exposure(average 91.8+/-5.2 dB{AA)), and 390 workers with low-level noise exposure(average 75.2+/-4.6 dB(A)). No significant difference was found in systolic or diastolic blood pressure between the two exposure groups. Prevalence of hypertension (> or = 160 mmHg systolic or > or = 100 mmHg diastolic) was higher in a younger age group (< or = 40 years old) of high-level noise exposure than of low-level noise exposure. However, the difference was not statistically significant. Furthermore, in younger ages, prevalence of. hypertension appeared to be higher in the hearing loss group (> or = 25dB at 1000 Hz or > or = 40 dB at 4000 Hz in at least one ear) than in the normal hearing group. From multiple regression analysis, hearing loss, body mass index, age, alcohol and family history of hypertension were proven to be predictors of diastolic blood pressure (p<0.02). When regression was performed for each age group, hearing loss was a strong predictor of diastolic pressure in the younger age group (p<0.01).

The distal tibial physeal plate is the second most frequently injured physis and the percentile incidence of its injury is reported to reach 11 percent of all physeal injuries. After physeal injuries, many complications may follow such as angulatory deformity, incongruity of the joint surface, and growth disturbance, which are well recognized. Therefore, for preventing these complications, we have to know mechanism of injury and position of foot in injury. There are several published articles about classification of these injuries. The first traumatological classification of ankle injuries in children is the one proposed by Bishop. Although there were many reports about classification since Bishop, those did not mention the position of foot in injury. Recently a modified classification by Dias and Tachdjian added the postiton of the foot during injury to the direction of the force as Lauge-Hansen did. There were only few reports about epiphyseal and physeal injuries of the ankle in Korea. Also, we could not find the reports which dealt with more than forty cases. The authors have made a clinical analysis on forty cases of childrens ankle fractures, and among them twenty-two could be followed over a year, who were treated at the Department of Orthopaedic Surgery, Kang-Nam St. Marys Hospital, from June 1981 to December 1986. Children were in age of 3 to 16 years. Forty cases were classified according to modified Dias and Tachdjians. 15 out of 40 cases (37.5%) had supination and external rotation injury, which is the most frequent mechanism of injury in this series. However, one case (2.5%) which was suspected to be axial compression type could not be accommodated to this classification. Twenty-seven cases were treated by gentle closed reduction and immobillization in a plaster cast, and thirteen by open reduction and internal fixation. Among the 22 cases who were followed over a year, five cases had complications, such as angulatory deformity, incongruity of the joint surface, and growth disturbance. Three cases out of these five cases had incongruity of the joint surface.

Fracture of distal one third of tibia is prone to develop angular deformity during weight bearing and delayed union by inadequate immobilization. Most surgeons have performed internal fixation with plate and screws or interlocking Kuentscher nail to provide stability to the fractured tibia. When open reduction and internal fixation is carried out, the periosteum and muscular attachments must be stripped off. And in interlocking Kuentschernailing extraoperative time needed to insert distal screw, and the medullary reaming destroys nutrient circulation by which fracture healing is hindered. However, flexible Ender nailing is a simple procedure which does not necessitate reaming, and also does not disrupt or strip off soft tissues at the fracture site. Authors carried out Ender nailing in 16 patients having distal tibial fractures who were treated at the Orthopaedic Department, Kang-Nam St. Mary's Hospital from February, 1985 to December, 1988. The results are as follows: 1. The radiological union was obtained at 13.3 weeks after operation, and primary healing was taken place. 2. Fractures could be securely fixed by intramedullary Ender nailing. 3. Mild angulation developed in 3 cases, but it did not affect the results. Through the results Ender nailing is proven to be an effective, reliable, and safe method in treatment of fracture of the distal one third of tibia with minimum residua and complication, and brings the natural fracture healing.

This study was started for the purpose of providing the basic data for continous managment of kidney transplantation patients after discharge. This study was conducted on 180 patients who received renal transplants at three hospital ( B, M. P) pusan, korea.. The data collection was done for june 1. to August 31. 2002. General characteristics, renal transplantaton characteristics. physical characteristics, the level of compliance and the degree of educational demand were done by the number and percentage. the mean. standard deviation. The level of compliance and educational demand followed by the characteristics of general and kidney transplantation were analyzed by t-test and ANOVA. The result were as fallows: 1. Man was higher than woman such as 60.0%, Mean age was 42.5 years old. Average total duration of after operation was 5.5 years. 2. Cases of systolic blood pressure over 140mmHg were 10.0%, cases of diastolic blood pressure over 90mmHg were 22.8% and obesity factor in BMI was 15.6%. The person who daily water intake amount is 5000cc was 0,6%, the case that daily urine output is below 1000cc was 8.9%. and the case that urine output is zero was 0,6%. 3. The mean score of compliance was 77.47 point. The score in medication part was highest such as 4.67 point, that in stress situation was lowest such as 3,50 point. 4. The average score of educational demand was 154.02 point. and physical state part was 4.36 points highest. activation part was 3.48 points lowest. As a role of nurse Confirmation of compliance is very important encourage to make good through regular hospital visitation. point out the noncompliance part and then increase compliance of renal transplantation patient As well there will be maintain the normal kidney function to satisfy educational demand through continous education.

A sensitive thermometer utilizing thermistor as a sensing element has been constructed in order to measure the temperatures in various ocular tissues. The Wheatstone bridge was used to detect the changes in thermistor resistance. The out-put of the bridge was fed into a single-stage differential DC amplifier and read by an micro-ammeter. There was a linear relationship between temperature and meter scale. The thermistor was inserted into the inferior conjunctival sacs of 158 healthy normal human eyes. The average temperature was found to be 35.14 +/- 1.08 (in C). No difference due to sex and age distribution was found to exists. Preliminary temperature measurement has been done on rabbits. Their results are shown graphically in Fig. 3.

Intracerebral hemorrhage is the most serious complication of cerebral arteriovenous malformations (AVM). To identify angiographic characteristics of AVM which correlate with a history of hemorrhage, we retrospectively analyzed angiographic findings of 25 patients with AVM. Nine characteristics were evaluated; these include nidus size, location, arterial aneurysm, intranidal aneurysm, angiomatous change, venous drainage pattern, venous stenosis, delayed drainage and venous ectasia. These characteristics were correlated with hemorrhage, which was seen in 18 (72%) patients of CT or MR images. Venous stenosis (P<.05) and delaved venous drainage (P<.05) well correlated with a history of hemorrhage. Arterial aneurysm and intranidal aneurysm also had a tendency hemorrhage although they did not prove to be statistically significant. Detailed analysis of angiographic finding of AVM is important for recognition of characteristics which are related to hemorrhage and may contribute to establishing a prognosis and treatment planning.

PURPOSE: The purpose of this study was to investigate perceptions of adequacy and job performance of the nurse assistants' nursing job as evaluated by registered nurses and nurse assistants in geriatric hospitals, and by caregivers from the same hospitals. METHODS: Participants included 62 registered nurses, 57 nurse assistants, and 64 patient caregivers who completed a measurement scale on the job of nurse assistants. Data collection was conducted from October to December, 2015. Data were analyzed using descriptive statistics and one-way ANOVA by IBM SPSS/WIN program version 21.0. RESULTS: There were significant differences by items in perception of adequacy of nurse assistants' nursing job of among the three groups. There was also a significant difference in perception of the nurse assistants' job performance among the three groups. CONCLUSION: For nurse assistants in geriatric hospitals, the Ministry of Health and Welfare needs to develop an appropriate job practice guideline. In addition, there should be periodic courses of retraining and continuing education for nurse assistants.
