Decolorization Kinetics of Sludge Protein Solution by ~（60）Coγ-Ray Irradiation/H_2O_2 Oxidation

In order to carry out decolorization, sludge protein solution, a dark brown close to black solution from activated sludge, was subjected to ⁶⁰Co γ-ray irradiation in the presence of hydrogen peroxide. UV/Vis spectrophotometric method was used to investigate the effect of H2O2 on the coloration apparent kinetics and rate constants of sludge protein solution under γ-ray irradiation. In addition, the effects of irradiation dose, initial sludge protein solution concentration, and pH value on the decolorization efficiency of sludge protein solution were studied. Results showed that the decolorization apparent kinetics of sludge protein solution was a first-order reaction. The solution decolorization percentage increased with the increase of irradiation dose or the decrease of initial sludge protein solution concentration. The examination results of pH value showed that the sludge protein solution could be more efficiently decolorized in alkaline media than in acid media. Moreover, sensory evaluation and foamability analysis indicated that irradiated samples under H2O2 oxidation showed better sensory score and foamability.     

分层教学在感觉统合训练中的探索

特殊教育的目的是使每个学生能最大限度地发挥学习潜在能力,得到切适本身条件的良好发展。分层教学就是根据学生的差异,从实际出发,实施有差异的,分组、分层的教学活动。这种教育教学模式能够充分体现特殊教育的个体差异性,满足特殊教育对象的需要,促进特殊教育对象的发展。     

Effects of audiovisual stimuli on psychological and psychophysiological responses during exercise in adults with obesity

The present experiment sought to further understanding of the effects of personalised audiovisual stimuli on psychological and psychophysiological responses during exercise in adults with obesity. Twenty-four participants (M_age = 28.3, SD = 5.5 years; M_BMI = 32.2, SD = 2.4) engaged in self-paced exercises on a recumbent cycle ergometer and three conditions (sensory stimulation [ST], sensory deprivation [DE], and control [CO]) were administered. Perceptual (attentional focus and perceived exertion), affective (affective state and perceived activation), and psychophysiological (heart rate variability) parameters were monitored throughout the exercise bouts. A one-way repeated measures analysis of variance was used to compare self-reported and psychophysiological variables (main and interaction effects [5 Timepoints × 3 Conditions]). The results indicate that ST increased the use of dissociative thoughts throughout the exercise session (η_p² = .19), ameliorated fatigue-related symptoms (η_p² = .15) and elicited more positive affective responses (η_p² = .12) than CO and DE. Accordingly, personally-compiled videos are highly effective in ameliorating exertional responses and enhancing affective valence during self-paced exercise in adults with obesity. Audiovisual stimuli could be used during the most critical periods of the exercise regimen (e.g., first training sessions) when individuals with obesity are more likely to focus on fatigue-related sensations.     

对城市与乡镇幼儿园810名3~6岁学龄前儿童感觉统合能力的测试研究

通过对８１０名不同性别、不同地域的３～６岁学龄前儿童感统合能力的测试发现,我国学龄前儿童感觉统合失调的发生具有普遍性,并存在明显的地域、性别、年龄、出生状态以及后天教育差异。建议相关人员高度重视并积极开展儿童感觉统合训练,以期预防和矫正獐感统合失调。     

对幼儿园中孤独症幼儿的感觉统合训练

孤独症是发生于儿童早期的一种涉及感知觉、情感、言语、思维和动作与行为等多方面的发育障碍。目前已有许多孤独症幼儿进入普通幼儿园或孤独症幼儿园中接受早期教育。本文探讨在幼儿园对孤独症幼儿进行感觉统合训练的意义,并重点介绍了感觉统合训练的内容,以及在训练过程中应遵循的基本原则。     

Supporting emotion regulation in individuals with ASD,ADHD and bipolar disorder through trauma-informed instruction and self-regulation strategies

Since the beginning of the COVID-19 pandemic, students have endured drastic changes in educational routines. Such disruptions can be especially challenging for students who struggle with executive functioning, self-regulation and emotion regulation, such as students with autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD) and bipolar disorder. Using a framework of trauma-informed instruction, the authors supported classroom teachers in implementing sensory spaces for students with ASD, ADHD and bipolar disorder. The project included professional development and funding for teachers to develop, procure and offer sensory tools and strategies to assist students in recognising and managing emotions. The authors collected data on the effectiveness of the sensory supports, combining teacher surveys and student behaviour data. Results indicated increased teacher knowledge on trauma-informed instruction and use of sensory supports to promote executive functioning and self-regulation and decreased target behaviours in students based on structured observation and anecdotal teacher feedback.     

论艺术教育的意义与价值

社会上存在很多对艺术教育的迷思,比如,艺术与教育的关系是什么?艺术是否可教?艺术完全是灵感的产物吗?艺术是否值得被教?艺术教育的作用是什么?符号理论可以表明艺术教育的可行性及价值。我们不应该将艺术仅仅视为达成某一具体目的的手段,而应该将其既看作目的,又视为手段。艺术完全是灵感的产物这一假设是没有根据的,学生的感觉回应和情感反应可以被教育,艺术教育是可能的,也是有价值的。

感觉统合训练对小学体育教学的启示

通过对感觉统合与感觉统合失调的概念与机制、发生原因与危害,以及感觉统合训练概念与理论依据、效应等进行分析与研究。指出人对外界的正确应答能力是不同感觉刺激在大脑中经无数次统合训练而习得的;儿童的感觉统合失调既有神经解剖学原因,也与刺激量与类别的缺失有关;其危害主要表现在学习障碍、心理障碍、社会适应障碍以及社会行为与生活能力障碍等方面;而感觉统合训练是防治儿童感觉统合失调的一种有效方法。在此基础上,提出了针对学童感觉统合失调问题的小学体育教学建议。
