Very job has and implies certain type of risk for the worker's health, depending on the conditions it is done with the use of tools or without them. Aplicated techniques: posturogram, baropodometry, Schober test, biocinemátic chain test, Fukuda test, propioceptiva plataform in personnel with special capabilities.     

Irregular working times and metabolic disorders among truck drivers: a review

A number of studies to better understand the complex physiological mechanism involved in regulating body weight have been conducted. More specifically, the hormones related to appetite, leptin and ghrelin, and their association to obesity have been a focus of investigation. Circadian patterns of these hormones are a new target of research. The behaviour of these hormones in individuals subject to atypical working times such as shiftwork remains unclear. Shiftwork is characterized by changes in biological rhythms and cumulative circadian phase changes, being associated with high rates of obesity and metabolic syndrome. Truck drivers, who work irregular shifts, frequently present a high prevalence of obesity, which might be associated with work-related factors and/or lifestyle. In this context, the aim of this paper was to discuss the relationship of body mass index, appetite-related hormones and sleep characteristics in truck drivers who work irregular shifts compared with day workers.     

有利砂体识别与解释

天然气的产量与砂岩的厚度,孔隙度,连通性,砂泥比等有密切的关系。为了解决砂体在空间以什么形态出现,其方向如何,纵向上如何变化,连通形式如何等问题,在前人研究的基础上,对篷来镇组某工区的砂体进行了精细识别和解释。在地震剖面上,砂体的响应一般表现为强振幅,低频率。孔隙性好,含气丰度高的砂体往往表现为速度低和极性反转的特点。但发现该工区的砂体在地震剖面上表现形式多变,甚至出现了合成地震记录与井旁地震记录严重不吻合的现象,故砂体识别工作不能遵循统一模式。因此,采用了多井约束,多层标定,分层解释来识别有利砂体。     

应用油藏规模序列法预测东营凹陷剩余资源量

随着油气勘探程度的不断提高，未发现的剩余油气资源越来越少。如何准确预测高勘探程度即成熟探区的剩余油气资源，成为石油投资者和油气资源评价工作者关注的焦点。详细探讨了油藏规模序列法预测油气资源的原理、方法、操作流程及存在的问题，并运用该方法对东营凹陷剩余可探明储量以油气成藏体系为评价单元进行了预测。研究表明，东营凹陷剩余可探明储量约为17.03×10⁸t，仍具有较高的勘探潜力，并且主要集中在东营中央背斜带和东营凹陷北坡两个油气成藏体系内。实践证明，由于油藏规模序列法合理回避了油气成因机理问题，减少了资源评价工作中人为因素的影响，使资源评价结果更为客观。     

Rethinking a universal framework in the psychiatric symptom-disorder relationship

Research on disparities in health and services should include a critical examination of how social, cultural, and contextual factors affect the connection between symptoms and psychiatric disorders. Systematic differences in this connection by these factors will mean that clinicians using a universalist approach to disorders may make more diagnostic errors for certain patients (e.g., ethnic minorities, the poor). Based on the literature on normative clinical decision-making, this study tests for whether the effect of specific psychiatric disorders on key symptoms is the same for certain groups of the population. The data come from the National Comorbidity Survey. Conditional probabilities of disorders and symptoms, the elements feeding into clinical decision-making, are calculated and tested for equivalence across various racial/ethnic, educational, income, and gender groups. We find some significant differences in the relation of key symptoms to disorders across groups. These findings should encourage testing relativistic frameworks in diagnostic nosology as a step to improve clinical decision-making and reduce diagnostic and treatment disparities in mental health services.     

盐岩在库车拗陷中的作用

库车拗陷的勘探实践表明，盐层与油气密切相关。通过对2条地震测线的分析发现，盐层、盐上地层、盐下地层变形看似孤立，实际相互影响。盐层构造变形一般发育在古隆起上部，盐上构造变形主要发生在盐枕构造的翼部，无盐地区主要发育基底卷入式构造。膏盐层可以延缓盐下地层烃源岩的热演化程度，可以改善盐下储层的储集性能；膏盐层本身也有可能成为油气储集层；膏盐层具有形成超压封闭和物性封闭的双重封闭机制，对盐下油气藏的保存极为有利；膏盐层的塑性流动特性，使得盐下构造圈闭在强烈的构造挤压中得以保存。     

长时压力监测数据处理新方法与应用研究

以传统试井理论和小波理论为基础，经过反复试验，寻找到了适合于处理长时压力数据的小波类型。应用多重阀值方法成功地侦测并剔除掉长时压力数据中的异常点；在Chee kin（2001）的线性回归方法基础上，建立了剔除噪音的新方法。模拟和实测长时压力数据的降噪效果说明了该方法不仅能有效地剔除数据中的噪音，还能完整地保留数据中的棱角特征。应用小波模极大值理论成功地将长时压力数据离散为相对独立的一系列不稳定数据段；在保留数据基本特征的前提下，应用最大压力—最大时间准则对原始数据实施了大幅度压缩；在数据处理的基础上，综合应用移动窗分析方法和正交试验方法解释了油田长时压力数据集。解释结果与传统试井解释方法具有一致性。     

基于新发展理念的川渝协同发展水平测度及对策研究*

以成渝城市群为代表的川渝协同发展即将成为继京津冀、长三角、粤港澳之后的又一重要增长极。以“创新、协调、绿色、开放、共享”为基点,建立包含五大发展理念的川渝协同发展指数,利用2008—2017年的数据进行测算,得出以下结论：第一,总体上,协同发展总指数逐年上升,但上升速度在缓慢下降,两地的协同发展具有较大的提升空间。第二,从分项指标来看,十年间创新发展指数和绿色发展指数的提升非常明显,协调发展指数和共享发展指数缓慢上升,而开放发展指数表现出先升后降的趋势。第三,为缩小与京津冀、长三角、粤港澳等发达地区的差距,需要坚持创新发展、着眼协调发展、引领绿色发展、扩大开放发展、实现共享发展,深度推进川渝协同发展,发挥重庆在新时代西部大开发中的支撑作用,在共建“一带一路”中的带动作用,在长江经济带绿色发展中的示范作用。
