昼夜节律计时系统的生物钟协调细胞和生理过程，并将其与日常周期相结合，进食模式也调节昼夜节律。生物钟基因和脂肪细胞因子具有昼夜节律性。这些基因的功能障碍参与了肥胖发展过程中这些脂肪因子的改变。食物可获得性促进与食物摄入相关的刺激，食物摄入是视交叉上核（SCN）外的昼夜节律振荡器。它的昼夜节律与可预测的每日用餐时间相一致。食物预期活动是由一个自我维持的昼夜节律调节的，其主要成分是食物振荡器。然而，下丘脑在调节能量平衡而不是食物摄入方面起着至关重要的作用。脂肪酸或其代谢产物可以通过参与能量和葡萄糖稳态调节的脑营养感受神经元来调节神经元活动。三餐时间表的时间表明与血浆胰岛素水平和先前的食物供应密切相关。通过改变食物摄入和饮食组成的时间，中枢和外周时钟之间的去同步化可导致外周时钟与中枢起搏器的解偶联，并导致代谢紊乱的发展。代谢功能障碍与昼夜节律有关，因此，生物钟基因的破坏导致血脂异常、胰岛素抵抗和肥胖。单独改变进食时间会对体重产生很大影响。生物钟的变化与摄食行为的时间改变和体重增加有关。因此，轮班工作与肥胖，糖尿病和心血管疾病的风险增加有关，因为不寻常的饮食时间和昼夜节律的破坏。中枢和外周水平的紊乱以及生物钟功能的最终破坏可导致肥胖。虽然CLOCK表达水平随着高脂饮食诱导的肥胖而增加，但过氧化物酶体增殖物激活受体（PPAR）α增加了肥胖受试者大脑和肌肉ARNT样1（BMAL 1）的转录水平。研究方法：本研究以关系筛选模式为基础。本研究采用自编的调查问卷，探讨高中教师对教育研究的态度。研究对象为大都市、乡镇、县11个不同部门的669名教师。本研究采用SPSS（Statistical Package for Social Sciences）for Windows 21.0统计软件包对数据进行统计分析。调查结果：研究发现，具有1-5年教龄的教师对教育科研的敏感度高于5年以上教龄的教师。他们“[关注]与其研究领域相关的科学期刊”的倾向也很明显。此外，在关注与其领域有关的科学期刊的教师中，女教师对教育研究的兴趣比男教师大。研究与实践的影响：基于这些结果，在职培训活动应组织和给予高中教师谁已经完成了五年的教学专业在公立学校和相关的大学部门，以提高教师对教育研究的态度，并鼓励教师遵循出版物与他们的领域。(C)版权所有© 2017 Ani Publishing Ltd
The biological clocks of the circadian timing system coordinate cellular and physiological processes and synchronizes these with daily cycles, feeding patterns also regulates circadian clocks. The clock genes and adipocytokines show circadian rhythmicity. Dysfunction of these genes are involved in the alteration of these adipokines during the development of obesity. Food availability promotes the stimuli associated with food intake which is a circadian oscillator outside of the suprachiasmatic nucleus (SCN). Its circadian rhythm is arranged with the predictable daily mealtimes. Food anticipatory activity is mediated by a self-sustained circadian timing and its principal component is food entrained oscillator. However, the hypothalamus has a crucial role in the regulation of energy balance rather than food intake. Fatty acids or their metabolites can modulate neuronal activity by brain nutrient-sensing neurons involved in the regulation of energy and glucose homeostasis. The timing of three-meal schedules indicates close association with the plasma levels of insulin and preceding food availability. Desynchronization between the central and peripheral clocks by altered timing of food intake and diet composition can lead to uncoupling of peripheral clocks from the central pacemaker and to the development of metabolic disorders. Metabolic dysfunction is associated with circadianConsequently, disruption of clock genes results in dyslipidemia, insulin resistance and obesity. Modifying the time of feeding alone can greatly affect body weight. Changes in the circadian clock are associated with temporal alterations in feeding behavior and increased weight gain. Thus, shift work is associated with increased risk for obesity, diabetes and -cardio-vascular diseases as a result of unusual eating time and disruption of circadian rhythm.-disturbances at both central and peripheral levels and, eventual disruption of circadian clock functioning can lead to obesity. While CLOCK expression levels are increased with high fat diet-induced obesity, peroxisome -proliferator-activated receptor (PPAR) alpha increases the transcriptional level of brain and muscle ARNT-like 1 (BMAL1) in obese subjects.Purpose: The main objective is to investigate high school teachers' attitudes relating to educational research with respect to demographic variables. Research Methods: The study is based on the relational screening model. Data was obtained through an adapted scale to determine high school teachers' attitudes toward educational research. The study was carried out with 669 teachers working at 11 different branches in metropolitan areas, towns, and counties. The data obtained in this study was analysed by SPSS (Statistical Package for Social Sciences) for Windows 21.0 program. Findings: It was observed that teachers with 1-5 years' occupational seniority showed more sensitivity towards educational research than those who had been working for more than five years. Their tendency to "[follow] scientific journals relating to their study field" was also found to be significant. Additionally, among teachers following scientific journals relating to their field, female teachers showed a greater interest in educational research than male teachers. Implications for Research and Practice: Based on these results, in-service training activities should be organised and given to high school teachers who have completed five years in the teaching profession at state schools and in relevant university departments in order to improve the attitudes of teachers towards educational research and encourage teachers to follow publications related to their field.
