Background: Propofol is being increasingly used as a intravenous anesthetic, but has no remarkable analgesic effect. Previous reports demonstrated that using of propofol with opioids had synergic effects, and decreased requiring dose of propofol. The purpose of this study was to examine the clinical usefulness of propofol-fentanyl intravenous anesthesia. Methods: Sixty patients of ASA status Ⅰ or Ⅱ undergoing breast mass excision were studied. Intravenous anesthesia was induced with fentanyl (2ug/kg) and bolus dose of propofol (2 mg/kg) and maintained with continuous infusion of propofol (6-10 mg/kg/hr). We measured loading, maintenance and total doses of propofol, changes of blood pressure, anesthesia time, and also observed the incidences of side effects of propofol anesthesia. Results: The bolus dose of propofol was administered within average injection time of 61.2 seconds. The systolic and diastolic pressure were significantly decreased after bolus injection of propofol (p<0.05). The administered total dose of propofol was 292.4±77.9 mg during average anesthesia time of 27.3 minutes. The incidences of injection pain, apnea and dizziness were 46.7%, 38.3% and 25% respectively. Conclusion: We concluded that the propofol-fentanyl intravenous anesthesia using infusion pump was clinically useful and safe method for short time operation.

Background: On the point of entering into the aged society, frailty will be recognized as a new geriatric problem in Korea. This study was conducted to identify clinical factors related to frailty in the community dwelling elderly. Methods: This was a cross-sectional study comprised of 515 participants among 834 potential subjects who were residents of three towns in Gyeong-ju and had health check-ups at a university hospital in the same region. Using the Korean Frailty Index, those with a total score of 5 or more were considered frail and those with scores 3 to 4 as prefrail. Socio-demographics, anthropometry and laboratory data were the selected clinical factors. Those younger than 65 years or with incomplete data were excluded. Finally, 447 participants were analyzed. Results: Among the participants, those identified as frail were 20 (4.5%), prefrail 72 (16.1%) and robust 355 (79.4%). By gender, the percentage of frail, prefrail and robust individuals were 3.2%, 17.4% and 79.5%, respectively, in men and 5.4, 15.2% and 79.4% in women (p=0.447). On ordinal logistic regression analysis, factors related to frailty were increased age (odds ratio [OR], 1.08; 95% confidence interval [CI], 1.01 to 1.17), functional disability (OR, 8.88; 95% CI, 4.46 to 17.68), chronic disease such as pulmonary disease (OR, 4.69; 95% CI, 1.47 to 14.99) or hypertension (OR, 2.23; 95% CI, 1.15 to 4.32), increased waist circumference (OR, 1.06; 95% CI, 1.01 to 1.11), decreased serum cholesterol (OR, 0.98; 95% CI, 0.97 to 0.99) and elevated blood urea nitrogen (OR, 1.07; 95% CI, 1.01 to 1.14). Conclusion: Clinical factors related to frailty were age, functional disability, chronic disease, waist circumference, serum cholesterol and blood urea nitrogen. Primary physicians should assess frailty when seeing elderly patients who have these factors.

This study was performed to measure the convective heat transfer coefficient, friction factor and visualize flow pattern inside the plate heat exchanger in a two-phase flow. The working fluid used in the experiment is HFE-7100. The experimental mass flux range was 30~70 kg/s⋅㎡. The range of inlet quality is 0.1~1, and the difference between inlet and outlet quality was from 0.1 to 0.7. Under the same average quality, the convection heat transfer coefficient and friction was more affected by the mass flux than difference between inlet and outlet quality. Also, the friction factor was rarely affected by average quality, but the friction factor increased as the mass flux increases. By flow visualization, the flow pattern according to the change in quality in the heat exchanger at 50 kg/s·㎡ and the average quality 0.35 and the flow pattern according to the mass flux at inlet quality 0.5, and the average quality 0.35 was confirmed.

Objectives: Many clinical factors has associated with metabolic syndrome, but well-known factors related to number of diagnosing criteria of metabolic syndrome have been a few. This study was conducted in order to find out clinical factors associated with number of metabolic syndrome`s component. 43 Methods: This study was a cross-sectional study. Using medical records of 324 participants who received health check ups at health promotion center of a university hospital in Gyeongju from March to July 2011, age, body mass index (BMI), white blood cell count, liver enzyme, fasting insulin, total cholesterol, uric acid, ferreting, the degree of fatty liver and esophagi is were collected and analyzed. The diagnostic criteria of metabolic syndrome were based on the National Cholesterol Education Program`s Adults Treatment Panel (NCEP ATP) III study.91 Results: Subjects who met to the diagnostic criteria of metabolic syndrome were 47 (14.5%). On ordinal logistic regression analysis, the clinical factors increasing components of metabolic syndrome were fatty liver (Odds ratio 2.60, 95% CI 1.48~4.537) elevated fasting insulin level (1.19, 1.08~1.31) and increasing age (1.07, 1.03~1.12).40 Conclusions: Clinical factors related to number of diagnosing criteria of metabolic syndrome were fatty liver, elevated fasting insulin level and increasing age.22
