Sit–stand workstations offer a potential strategy to reduce prolonged occupational sitting. This controlled intervention study examined the effects of an environmental intervention on occupational sedentary time, musculoskeletal comfort and work ability, and the usability of sit–stand workstations in office work via a self-reported questionnaire. The intervention group (n?=?24) used sit–stand workstations during the 6-month intervention period, and the control group (n?=?21) used traditional sitting workstations. The results showed that working at sit–stand workstations can reduce sitting time significantly compared to control workstations (?6.7% vs. 5.0%, p?=?.019), which is reallocated mostly to standing (r?=??0.719, p?comfort in the neck and shoulders (p?=?.028), as well as work ability (p?=?.022). The majority of intervention subjects rated sit–stand workstation adjustability as good (83.3%), and 75.0% were satisfied with the workstation. About 41.7% of the intervention participants, who were exclusively female, used the sit–stand function on a daily basis. While the environmental change alone was effective, it is likely that promoting the daily use of sit–stand workstations with counselling would lead to even more substantial positive effects.  相似文献   

Lamaze breathing: what every pregnant woman needs to know     

Lothian JA 《The Journal of perinatal education》2011,20(2):118-120

Lamaze breathing historically is considered the hallmark of Lamaze preparation for childbirth. This column discusses breathing in the larger context of contemporary Lamaze. Controlled breathing enhances relaxation and decreases perception of pain. It is one of many comfort strategies taught in Lamaze classes. In restricted birthing environments, breathing may be the only nonpharmacological comfort strategy available to women. Conscious breathing and relaxation, especially in combination with a wide variety of comfort strategies, can help women avoid unnecessary medical intervention and have a safe, healthy birth.  相似文献   

论元朝政府对阵殁群体的抚恤     

于宏伟 《安顺学院学报》2020,(1):69-73

元朝时期战争频率较前代较高,众多军吏在早期统一战争、中期内部战争、晚期农民战争中阵殁,元朝政府采取了一系列的抚恤政策。阵殁的军吏可以分为身陷困境,捐躯殉职;参与作战,英勇牺牲;战斗负伤,不治身亡;行军途中,不幸卒殁四种阵殁群体。政府采取的抚恤手段主要有:追封阵殁者及上谥、官方料理丧葬事宜、赏赐钱物土地户民、荫叙亲属袭晋职位、亲侍汤药关怀伤者、旌表立祠后世传颂、政治指定结为姻亲等。除此以外,后抚恤时代的抚恤则是统治者个人情感的转移与承接,是另外一种“非抚恤”的“抚恤”。  相似文献   

Effect of Air Velocity on Thermal Comfort under Thermal Environment Ramp Changing   总被引：1，自引：0，他引：1  

嵇赟喆  涂光备  孙琳 《天津大学学报(英文版)》2004,10(4):291-296

Set points of the indoor air temperature and relative humidity in short-term staying location were studied. In this condition, the thermal reaction of human body varied with the ramp changes of the environmental thermal parameters. The change rules of about 60 subjects‘ thermal reaction to the ramp change of environment were surveyed, and the effect of air movement on the thermal reaction during transient condition was considered by using a questionnaire. With the experimental results and research findings under stable condition, a way to set environmental parameters of short-time staying location was recommended.  相似文献   

船舶空调热舒适控制策略     

刘红敏  龚志豪  王一初  徐斌 《上海海事大学学报》2019,40(4):78-82

针对传统船舶空调PID控制动态性能和抗干扰能力弱的缺点,设计一种将PID控制与模糊理论相结合的模糊PID控制。利用MATLAB,分别对传统的PID控制、模糊控制和模糊PID控制进行仿真比较,发现模糊PID控制具有控制精度高、超调小、波动小、动态响应快的特点。船舶航行于复杂的环境中,舱室内热舒适温度随着外界环境变化需不断调整,对船舶空调温度控制系统采用模糊PID控制可以精确、快速地使船舶舱室达到热舒适的状态。  相似文献

考虑视觉感官舒适度的园林建筑层次设计     

张入心 《科技通报》2014,(9)

利用传统算法在进行园林建筑设计的过程中,由于园林建筑层次受到设计人员主观因素的影响较大,难以进行准确的层次提取,造成设计效率和园林建筑层次感降低。为此,提出考虑视觉感官舒适度的园林建筑层次设计方法。根据韦伯-费普勒相关原理,建立园林中不同建筑物数目与视觉感官舒适度模型。针对模型中不同建筑物的主要特征进行提取,获取不同建筑物主要特征之间的映射关联性,从而完成视觉感官舒适度的园林建筑层次设计。实验结果表明,利用本文算法进行园林建筑层次设计,能够显著降低设计时间,提高园林建筑的层次感,效果令人满意。  相似文献

A young mother shares the stories of her two sons'' births. Her first birth experience was complicated by muscle spasms and changes in her baby''s heart rate during labor and, later, by medical problems with her baby in the days after birth. The mother''s strength and commitment shine through at every twist and turn during labor and the days after her son''s birth. Two years later, in contrast to her first son''s birth, the mother''s second son was born so quickly that labor presented a different set of challenges. The mother''s confidence in birth and in herself are essential facets of the stories of the births of her two sons.  相似文献
