To investigate the effects of a single high-load (80% of one repetition maximum [1RM]) set with additional drop sets descending to a low-load (30% 1RM) without recovery intervals on muscle strength, endurance, and size in untrained young men. Nine untrained young men performed dumbbell curls to concentric failure 2–3 days per week for 8 weeks. Each arm was randomly assigned to one of the following three conditions: 3 sets of high-load (HL, 80% 1RM) resistance exercise, 3 sets of low-load [LL, 30% 1RM] resistance exercise, and a single high-load (SDS) set with additional drop sets descending to a low-load. The mean training time per session, including recovery intervals, was lowest in the SDS condition. Elbow flexor muscle cross-sectional area (CSA) increased similarly in all three conditions. Maximum isometric and 1RM strength of the elbow flexors increased from pre to post only in the HL and SDS conditions. Muscular endurance measured by maximum repetitions at 30% 1RM increased only in the LL and SDS conditions. A SDS resistance training program can simultaneously increase muscle CSA, strength, and endurance in untrained young men, even with lower training time compared to typical resistance exercise protocols using only high- or low-loads. 相似文献

PISA presents a new image for academic achievement, which has prompted Japanese education reforms over the past decade to innovate teaching and learning for ‘PISA-style literacy’. Supported by theoretical foundations, particularly with regard to the concept of ‘PISA literacy’ and ‘authentic assessment’, these reforms have accomplished progress in the focus on higher order competencies, such as application and the development of new assessment strategies. However, more recently, various critical discussions of ‘PISA literacy’ are underway in the Japanese academy. They interrogate it more critically and reveal the narrow emphasis on functional application and technical operation. Current assessment practices, which tend to fall into ‘criteria compliance’, are in urgent need of review. There is a need to extend the critical discussions in progress to the new assessment strategies. This paper responds to this, by considering the Japanese acceptance of ‘PISA literacy’ and its assessment, discussing the features and limitations. 相似文献

The Department of Education in the Philippines has undertaken initiatives to restructure the curriculum for secondary schools as part of its ongoing effort to improve the quality of learning. After a decade of study, the Department produced a new basic education curriculum, as the 2002 Basic Education Curriculum. All public schools in the country were mandated to implement the curriculum at the start of 2002–2003 school year. Makabayan (nationalistic or patriotic) is one of the learning areas in the Basic Education Curriculum along with English, Filipino, Science and Mathematics. Makabayan from First to Fourth Year is designed to develop the personal, social and work special skills of learners especially their interpersonal skills, empathy with other cultures, vocational efficiency, problem-solving, and decision-making in daily life, that is, to develop socio-cultural and politico-economic literacy. This paper describes the context and content of the Makabayan curriculum and the extent to which it develops in learners a sense of citizenship, that is, a healthy personal and national self-concept. To delimit scope, this paper focuses on the study of geography only as one of the components of Araling Panlipunan (Social Studies) in the secondary school Makabayan Curriculum, using the results of a study of third year high school students' learning of geographic knowledge and skills as bases of empirical data. Key Words: citizenship, geographic literacy and competency, Makabayan curriculum, secondary education 相似文献

The development of effective strategies for planned change presents a challenge to an organization operating in a modern, complex society. A change agency often faces two barriers to the diffusion of innovations —the lack of direct contact with individual receivers on a daily basis, and limited and perhaps shrinking resources. Two strategies which help a change agency address these barriers are: a) the use of co‐change agencies in innovation development and b) the diffusion of innovations through other organizations at the system‐receiver level. The use and effectiveness of these modifications to the traditional diffusion model are illustrated in the development and diffusion of a health education program called Foods for Health. 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

We present a microfluidic device designed for maintenance and culture of non-adherent mammalian cells, which enables both recirculation and refreshing of medium, as well as easy harvesting of cells from the device. We demonstrate fabrication of a novel microfluidic device utilizing Braille perfusion for peristaltic fluid flow to enable switching between recirculation and refresh flow modes. Utilizing fluid flow simulations and the human promyelocytic leukemia cell line, HL-60, non-adherent cells, we demonstrate the utility of this RECIR-REFRESH device. With computer simulations, we profiled fluid flow and concentration gradients of autocrine factors and found that the geometry of the cell culture well plays a key role in cell entrapping and retaining autocrine and soluble factors. We subjected HL-60 cells, in the device, to a treatment regimen of 1.25% dimethylsulfoxide, every other day, to provoke differentiation and measured subsequent expression of CD11b on day 2 and day 4 and tumor necrosis factor-alpha (TNF-α) on day 4. Our findings display perfusion sensitive CD11b expression, but not TNF-α build-up, by day 4 of culture, with a 1:1 ratio of recirculation to refresh flow yielding the greatest increase in CD11b levels. RECIR-REFRESH facilitates programmable levels of cell differentiation in a HL-60 non-adherent cell population and can be expanded to other types of non-adherent cells such as hematopoietic stem cells. 相似文献

Comparisons over time of the inputs and outputs of polymer chemistry research in Japan show that the academic institutionalisation of this discipline took place after the most creative period in its research had been reached. Early interest in the development of the field had been stimulated by Japanese industry in response to major discoveries made in Western Europe and the USA. 相似文献

This short review provides an overview of the impact micro- and nanotechnologies can make in studying epigenetic structures. The importance of mapping histone modifications on chromatin prompts us to highlight the complexities and challenges associated with histone mapping, as compared to DNA sequencing. First, the histone code comprised over 30 variations, compared to 4 nucleotides for DNA. Second, whereas DNA can be amplified using polymerase chain reaction, chromatin cannot be amplified, creating challenges in obtaining sufficient material for analysis. Third, while every person has only a single genome, there exist multiple epigenomes in cells of different types and origins. Finally, we summarize existing technologies for performing these types of analyses. Although there are still relatively few examples of micro- and nanofluidic technologies for chromatin analysis, the unique advantages of using such technologies to address inherent challenges in epigenetic studies, such as limited sample material, complex readouts, and the need for high-content screens, make this an area of significant growth and opportunity. 相似文献
