社会支持对考试应激的影响 总被引:2,自引:0,他引:2
目的了解社会支持对考试应激的影响。方法采用焦虑自评量表和社会支持量表分别对727个学生考试前1个月、考试期间考试焦虑分数及社会支持情况进行调查,比较分析考试焦虑分数与社会支持因素的关系。结果考试焦虑分数与客观支持、来自同学和老师的主观支持以及社会支持的利用度成反比。结论家长和学校给予学生足够的社会支持,以及让学生参加适当的社会活动,培养他们利用社会支持的能力,有助于让学生减缓考试应激的水平 相似文献

The Design and Analysis of Hospital Utilization Studies 总被引:1,自引:1,他引:0

This study describes a method for determining the number of radiographic rooms devoted to emergency radiology that would be
required to keep mean patient waiting time at a desired level.
A desired mean waiting time for patients must be determined. In our setting, a mean waiting time of 8 minutes resulted in
few complaints. The waiting time then sets the required utilization rate of available capacity. Daily and hourly volume and
variability in volume of examinations were measured over a 3-month period. This represents the demand. The needed number of
rooms is determined by comparing demand with effective available capacity for different numbers of rooms.
To maintain an 8-minute mean waiting time, 50% utilization of capacity is required. Mean demand on Sundays is 176 examinations.
Five rooms are required, since this gives a 180-examination effective capacity.
Using waiting time as the primary decision criterion for making capacity decisions in emergency radiology has several advantages:
the method is easy to use, volume variability is taken into account, and the focus is on service to patients. 相似文献

Summary Reticulocyte count comparisons were made on ten trained and ten sedentary college males before and immediately after heavy
exercise and following 15 min of recovery. No significant differences occurred within or between groups; in fact, all means
were within the normal range. Previous findings were discussed. It was concluded that a physiologically significant increase
in reticulocytes does not occur as a result of exercise or training and therefore can not be a mechanism for increased maximal
oxygen uptake. 相似文献

Summary Four well-trained male subjects worked for periods of 6 h on bicycle ergometers at work loads requiring about 47% of their maximal aerobic capacity. In one series of studies they received only water; in a second series they received 100 g of sucrose containing 100 c U-C14-labelled sucrose at the beginning of the fourth hour of work. In a third series of experiments, the same subjects received 100 g of non-labelled sucrose at the beginning of the fourth hour. During the experiment without U-C14-labelled sucrose, blood samples were withdrawn and analysed for glucose, lactate and pyruvate content. Data from C14O2 recovery in expired air showed a good correlation with the amount of carbohydrate oxidized during the sucrose experiment. Peak values for the respiratory exchange ratio showed the same time response as those observed for the C14O2 in the expired air. It is concluded that the observed rise in RQ after sucrose ingestion, under the conditions studied, is of metabolic origin, resulting from a complete conversion of pyruvate to CO2. 相似文献

Objective: The specific objectives of this study were to: 1) study the effect of moderate-to-severe asthma on patient's Health-Related Quality of Life (HRQoL) as measured by the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) and 2) evaluate the construct validity of a modified and shortened version of the Living With Asthma Questionnaire (ms-LWAQ) using the SF-36 as a concomitant measure of HRQoL. Methods: Cross-sectional, telephone or mail surveys of asthmatic patients enrolled in two central Florida managed care organizations. Results: All subscales of the SF-36 and four subscales of the ms-LWAQ demonstrated adequate reliability in this population (Cronbach >0.72). The subscales of the SF-36 most affected by patient's asthma were: general health perceptions, vitality and physical role functioning. These three subscales were correlated with four subscales of the ms-LWAQ: consequences, seriousness, affect and leisure. Six of the eight SF-36 subscales and all of the ms-LWAQ subscales were associated with patient's emergency department and hospital utilization. Conclusion: The ms-LWAQ and SF-36 are valid as useful measures of asthma patient's HRQoL in this cross-sectional study. Severity of disease, as measured by health care utilization, was significantly associated with HRQoL. 相似文献
