Objectives: The purposes of this study were to investigate nursing students' knowledge and attitudes toward the elderly, to examine the correlation between knowledge and attitudes, and to identify predictors of nursing students' attitudes toward the elderly. Method: Study participants were 195 nursing students who enrolled in a university located in Gwangju. Data were collected using structured questionnaires. Results: The average FAQ Ⅰ score for nursing students in this study was 50.2%. The level of nursing students' knowledge was relatively low compared to knowledge of Western nursing students in previous studies. Moreover, the average scores of psychological dimension and family/sociological dimension were lower than those of physical/physiological dimension. Negative biases were prevalent when the biased scores were computed. Nursing students also reported a little preference for working with older patients after graduation. Although the average attitude score was in a neutral range, the number of items in a negative attitude score range were more than those in a positive attitude score range. Contrary to expectation, the correlation between knowledge and attitude was not statistically significant. Nursing students who have clinical experiences with the elderly reported higher scores on FAQ Ⅰ than their counterparts. A current relationship with elderly living in their household was a significant predictor of nursing students' attitudes toward the elderly. Conclusion: Results from this study suggest that nursing education should be directed to increase the nursing students' knowledge and positive attitudes toward the elderly. Exposure to well elderly as clients before they are hospitalized or institutionalized may be helpful to increase nursing students' positive attitudes toward the elderly.

This study was performed to investigate the effects of diet pattern on lipid and cholesterol metabolism in rats. Sprague-Dawley rats were fed four types of diets for four weeks, respectively: a control diet, 40% energy restriction diet, high animal fat diet or high plant fat diet. Control and 40% energy restriction diets were composed by AIN-76 diet and high fat diets were composed by 53.6% of animal or plant fat. In rats fed with 40% energy restriction diet showed significantly low body weight gain, liver, abdominal and subcutaneous adipose tissue weights compared to rats fed with control diet. In rats fed with high animal fat diet showed significantly high body weight gain, liver, abdominal and subcutaneous adipose tissue weights compared to rats fed with control diet. In rats fed with high plant fat diet showed similar body weight gain. The increase of adipose tissue weight was much smaller in rats fed with high plant compared to rats fed with high animal fat diet implying the effect of high fat diet on fat accumulation on adipose tissue may defend on the kinds of fats. Plasma total cholesterol and triglyceride concentrations were significantly decreased in rats fed high plant fat diet. However, liver total cholesterol and triglyceride concentrations were signigficantly increased in rats fed high animal fat diet. The fibrinolytic activity of serum was significantly increased in rats fed high plant fat diet compared to rats fed with control diet.

This trial was conducted on 10 Korean native goat kids which were born by estrus synchrozation and seperated from their dams at 8 days of age. The kids were fed mesh raw milk from Holstein cows at regular intervals of three times daily by infant nursing bottle from 8 up to 59 days of age, and also provided pre-starter as well as Italian ryegrass hay from 14 days of age. Throughout the experimental period, daily amount of milk, pre-starter and Italian ryegrass hay consumed per kid was recorded. Live weight was measured at regular intervals of 3 days from 5 days of age till weaning, and thereafter at intervals of 15 days up to 119 de s of age. Growth rate per day were calculated during the total gain in weight. The average daily amount of milk consumed per kid was about 474 ml at the beginning and thereafter increased progressively until kids reached their peak(about 1,300 ml) by 41 days of age. The average total milk consumption per kid over the experimental period was about 51,000 ml. The kids started eating pre-starter and Italian ryegrass hay regularly around 32 days of age. The average daily amount of pre-starter consumed per kid was 10-l3g during 32-47 days of age and reached about 70g at weaning. The average daily amount of Italian ryegrass hay consumed per kid was 30g around 32 days and reached about 80g at weaning. The average birth weight of experimental kids was 1.79(±0.23) kg. The average daily gains of experimental kids showed 0.1 kg througout the experimental period and the average body weight of kids reached 8.14 kg at weaning .After weaning, the average body weight of kids reached 8.53 kg at 74 days, 9.55 kg at 89 days, 13.3 kg at 119 days of age, respectively.

ON THE ARC LENGTH UNDER INVERSION

현진오,양창홍 濟州大學校 師範大學 科學敎育硏究所 1993 科學敎育 Vol.10 No.1

Two points P and P' of the plane are said to be inverse with respect to a given circle (0)_(R), if OP·OP'=R^(2) and also if both points are on the same side of O. Circle (O)_(R) is called the circle of inversion and the transformation which sends point P into point P' is known a s an inversion. In this paper we consider the curves in two dimensional Euclidean space R^(Z) and prove that the length of a regular new curve segment β(t) of the inside curve α(t) under inversion is equal to the length of a regular curve segment a(t) by scalar multiple.

혼합물을 냉매로 사용할 경우, 냉매의 성능 평가를 위해 기-액 상평형 데이터가 필수적으로 요구된다. 본 연구에서는 HFC-134a와 propane의 이성분계 상평형 데이터를 얻기 위해 273.15, 283.15, 283.15, 303.15, 313.15, 323.15K의 조건에서 실험을 실행하였다. 상평형 실험 장치로는 circulation type의 장치를 사용하였다. 실험데이터는 Peng-Robinson-Stryjek-Vera(PRSV)상태방정식과 NRTL excess Gibbs free energy model을 결합한 식에 다섯 개의 혼합법칙(Huron-Vidal original and modified equation)들을 이용하여 상관관계를 알아보았다. PRSV 상태방정식을 이용하여 얻은 데이터는 실험 데이터와 만족할 만한 일치를 볼 수 있었다. 실험은 실행한 모든 온도에서 공비점이 형성하는 것을 확인하였다. Vapor-liguid equilibrium(VLE) data are essential when using mixtures as a refrigerant. The VLE data of binary mixture containing 1, 1, 1, 2-tetrafluoroethane and propane were measured at 273.15, 283.15, 293.15, 303.15, 313.15 and 323.15K using circulation type experimental apparatus. The experimental data were correlated with five mixing rules combined with the Peng-Robinson-Stryjek-Vera equation of state. We compared the data obtained by using the PRSV EOS with experimental data and a satisfactory consistency of model predictions with experimental data were obtained. Azeotropic behavior has been observed in all these mixtures.
