The purpose was to determine if the muscle swelling, echo intensity, and fatigue responses to blood flow restriction differs based on cuff width (Experiment 1), applied pressure (Experiment 2), and sex. Ultrasound of muscle was taken before and after exercise. In Experiment 1 (n = 96), men swelled more than women and more with a narrow cuff than a wide cuff (0.60 cm vs. 0.52 cm). Expressed as a percentage change, there were no longer differences between cuffs (Narrow: 15% vs. Wide: 14%) or sex (Men: 14% vs. Women: 15%). Echo intensity remained unchanged. Women required more repetitions to reach task failure in sets 2, 3, and 4. In Experiment 2 (n = 87), men swelled more than women (Men: 0.46 cm vs. Women: 0.31 cm). Expressed as a percentage change, there were no differences. Echo intensity decreased in both conditions and to a greater extent with a higher applied pressure. If the acute muscle swelling response is important for initiating long term adaptation, then our results indicate that neither cuff width, sex, nor applied pressure will differentially impact the adaptation observed via this mechanism. Changes in echo intensity were inconsistent and the utility of this measurement may need to be reconsidered. 相似文献

In 1988 UAJ completed the first phase of its initial plan, thus enabling an assessment of the cost-effectiveness of UAJ and a forecast of its future based on available data. The cost per student at UAJ is 2/5, 1/2, and 3/4 of that at national, public, and day programs of private universities, and 1.1 times and 6.7 times of that at evening and correspondence programs of private universities repectively. The projected cost per graduate is slightly lower than that at national universities and 1.1, 1.9 and 2.3 times of that at public, correspondence and day, and evening programs of private universities respectively. The cost per credit is 1.3, 1.5, 2.2, 2.4 and 4.6 times of national and public universities, day, evening, and correspondence programs of private universities respectively.The simulations indicate that the cost per credit can be decreased by expanding the operation of UAJ to a nationwide scale, employing a surface circuit or satellite system; however, it is necessary that the number of students be doubled in order to make the cost per credit equivalent to that at public universities. However, even when the number of students is four times, the cost per credit is not equivalent to that at day programs of private universities regardless of what method is used. Although the current cost per credit is higher than that of conventional universities, changes in cummunication technology and student characteristics could alter the cost-effectiveness of UAJ. 相似文献

While some governments in Sub-Saharan Africa have abolished tuition to achieve universal primary education (UPE), few studies have examined the impacts of the UPE policy beyond school enrolment. This study estimates the impact of the UPE policy in Uganda on overall primary education attainments by using data including 940 rural households. We find that UPE has decreased delayed enrolments and increased grade completion rates up to the fifth grade and its effects are especially large among girls in poor households. Yet, schools in Uganda still face further challenges in terms of low internal efficiency and the unequal quality of education. 相似文献

Conclusion The University of the Air seems to have been favourably accepted by students after the first term's experience, and it can
be assumed that the University activities will be developed in the future. The radio and television programmes broadcast via
the University of the Air Foundation broadcasting station are listened to and watched by many people other than students of
the University. The potential therefore for the social education of the public at large can be said to be enormous.
Acknowledgement: The author expresses his thanks to the staff of the University of the Air Foundation and of the National
Centre for the Development of Educational Broadcasting, and also to Professor Donald P. Ely, Syracuse University, for his
helpful suggestions. 相似文献

Although the methods for medical education continue to evolve due to the development of medicines, the cadaver dissection course still plays a fundamental role. The cadaver dissection course allows students to learn to handle instruments correctly while actively exploring three-dimensional anatomy. However, dissection comes with the risk of accidental injury. In recent years, the number of classes offered for the cadaver dissection course has decreased while the amount of knowledge required in clinical medicine has increased. Simulation-based education (SBE) has been proven to be an effective educational method that enhances the development of practical skills by integrating learners' knowledge and skills. This study aimed to investigate the effect of SBE as a preparatory education course when taken prior to a medical student's enrollment in the cadaver dissection course. In the present study, an SBE assuming practical cadaver dissection course was performed in the Clinical Simulation Center. The frequency of injury rates per 1000 h of cadaver dissection course was significantly less in 2017 and 2018 compared to that in 2016. Two years after the implementation of the SBE, average student self-efficacy scores and written examination scores significantly increased, whereas self-contentment scores were relatively unchanged. The results showed that the implementation of SBE decreased the incidence of injuries and improved students' overall self-efficacy scores and increased acquisition of knowledge evident on written examination score. Therefore, SBE as a preparatory education course may effectively promote the combined development of dissection skills and anatomical knowledge in the subsequent fundamental cadaver dissection course. 相似文献
