  • 文章类型: Systematic Review
    目的:总结成人肥胖神经影像学研究的结果(结构,静息状态,基于任务,扩散张量成像)于2010年出版,重点是将性别作为分析中的重要生物学变量,找出性别差异研究的差距。
    结果:神经影像学研究显示肥胖相关的大脑结构改变,函数,和连通性。然而,通常不考虑性别等相关因素。我们进行了系统回顾和关键词共现分析。文献检索确定了6281篇文章,其中199人符合纳入标准。其中,只有26人(13%)认为性别是分析中的重要变量,直接比较性别(n=10;5%)或提供单性别/分类数据(n=16,8%);其余研究控制性别(n=120,60%)或在分析中不考虑性别(n=53,27%).综合基于性别的结果,肥胖相关参数(例如,身体质量指数,腰围,肥胖状态)通常可能与男性更强烈的形态学改变和女性更强烈的结构连通性改变有关。此外,肥胖女性在情感相关区域普遍表现出反应性增加,而肥胖男性通常在运动相关区域表现出反应性增加;在进食状态下尤其如此。关键词共现分析表明,干预研究尤其缺乏性别差异研究。因此,尽管已知存在与肥胖相关的大脑性别差异,很大一部分文献介绍了当今的研究和治疗策略,并没有具体检查性别影响,这是优化治疗所需要的。
    OBJECTIVE: To summarize the results of adult obesity neuroimaging studies (structural, resting-state, task-based, diffusion tensor imaging) published from 2010, with a focus on the treatment of sex as an important biological variable in the analysis, and identify gaps in sex difference research.
    RESULTS: Neuroimaging studies have shown obesity-related changes in brain structure, function, and connectivity. However, relevant factors such as sex are often not considered. We conducted a systematic review and keyword co-occurrence analysis. Literature searches identified 6281 articles, of which 199 met inclusion criteria. Among these, only 26 (13%) considered sex as an important variable in the analysis, directly comparing the sexes (n = 10; 5%) or providing single-sex/disaggregated data (n = 16, 8%); the remaining studies controlled for sex (n = 120, 60%) or did not consider sex in the analysis (n = 53, 27%). Synthesizing sex-based results, obesity-related parameters (e.g., body mass index, waist circumference, obese status) may be generally associated with more robust morphological alterations in men and more robust structural connectivity alterations in women. Additionally, women with obesity generally expressed increased reactivity in affect-related regions, while men with obesity generally expressed increased reactivity in motor-related regions; this was especially true under a fed state. The keyword co-occurrence analysis indicated that sex difference research was especially lacking in intervention studies. Thus, although sex differences in the brain associated with obesity are known to exist, a large proportion of the literature informing the research and treatment strategies of today has not specifically examined sex effects, which is needed to optimize treatment.

    背景:驾驶分心识别方法的现有选择是基于特定的研究角度,并且没有提供有关整个视野的全面信息。
    方法:我们对以前的研究进行了系统回顾,旨在提出合适的研究方法来识别驾驶员的分心状态。首先,本文从五个数据库(WebofScience,ScienceDirect,SpringerLink,IEEE,和TRID),并确定了2000年至2020年的1,620份同行评审文件;这1,620份文件经过了书目分析和共现网络分析。从时间、国家,出版物,作者和关键词。第二,对发表的37篇论文进行了筛选,并对这37篇论文提出的驾驶分心识别方法进行了总结和分析。
    结果:结果表明,该领域自2013年以来一直很普遍;美国等国家,英国,德国,澳大利亚,中国,加拿大在这一领域的研究处于前沿,相关国家之间的合作相对密切。作者之间的合作具有聚集性,而手机作为主关键词几乎与其他关键词节点相连;基于视频监控数据源的深度学习算法识别模型已成为主流热点干扰识别方法。基于车辆动力学数据的机器学习算法识别模型,驾驶员生理学,和眼动数据源具有特定的优点和缺点。
    结论:结果可以帮助人们全面,系统地了解驾驶分心的现状,为研究者选择后续的驾驶分心识别模型提供更好的理论支持,为未来驾驶分心识别提供研究方向。
    BACKGROUND: The existing selection of driving distraction recognition methods is based on a specific research perspective and does not provide comprehensive information on the entire field of view.
    METHODS: We conducted a systematic review of previous studies, aiming to come up with appropriate research methods to identify the driver\'s distraction state. First, this article selects four sets of search keywords related to driving distraction discrimination from five databases (Web of Science, ScienceDirect, Springer Link, IEEE, and TRID) and identifies 1,620 peer-reviewed documents from 2000 to 2020; these 1,620 documents underwent bibliographic analysis and co-occurrence network analysis. The co-occurrence coupling relationship is analyzed from the aspects of time, country, publication, author and keywords. Second, 37 papers published were screened, and the driving distraction recognition methods proposed by these 37 papers were summarized and analyzed.
    RESULTS: The results show that this field has been prevalent since 2013; countries such as the United States, Britain, Germany, Australia, China, and Canada are in the forefront of research in this field, and the cooperation between related countries is relatively close. The cooperation between authors is characterized by aggregation, and the mobile phone as the main keyword is almost connected to other keyword nodes; the recognition model of deep learning algorithm based on video surveillance data sources has become the mainstream hot spot distraction recognition method. The recognition model of machine learning algorithm based on vehicle dynamics data, driver physiology, and eye movement data sources has specific advantages and disadvantages.
    CONCLUSIONS: The results can help people to understand the current situation of driving distraction comprehensively and systematically, provide better theoretical support for researchers to choose the subsequent driving distraction recognition model, and provide research direction for driving distraction recognition in the future.

In terms of purpose, this is an applied study and regarding type, it is a scientometric and co-occurrence analysis. The researchers conducted a search in WoS, Scopus and PubMed databases. The abstract and full text of 25 out of 71 articles were selected to be included in the study. Then, the citation and altmetrics indicators were investigated. In addition, VOSviewer software was utilized to analyze and visualize keywords and map of articles. Finally, the full texts of all articles were analyzed to be provided more information about the types of analyses in these articles. The findings showed that 25 articles were published between 2016 and 2021. Co-occurrence map of articles showed that the three variables of motivation, learning, and engagement have been considered in gamified education studies and most studies have examined gamification in the e-learning environment. Finally, the content analysis of the articles showed that 344 articles were included and analyzed in these 25 systematic reviews and meta-analyses. The types of analyzes performed on these 344 articles categorized them in 7 categories including Country/Territory, Duration of intervention, Lessons/content and the level of gamified educational course, the number of learners, platforms, the game elements and the theories.

    可持续补救,促进在环境清理活动中使用更可持续的做法,是一个激烈的国际发展领域。尽管与可持续补救评估有关的许多指标已被利用并发表在相关学术文献中,它们很难统一,国家之间的重点也各不相同。从CNKI的文献检索,Springer,ScienceDirect,和Wiley在线数据库,我们对相关国家和国际文献进行了系统和文献计量分析,以定义最常考虑的可持续性指标,它们在从可持续性角度选择补救技术或现场管理方法方面发挥着重要作用。在应用共现分析和社会网络分析之后,结果表明,1)环境标准最常用于评估修复技术,特别是中国出版物对社会标准的重视程度大大降低;2)在过去20年中,出版物数量不断增加,可持续修复已经经历了初始阶段,上升阶段,以及突发或更广泛的采用阶段,其特点是研究主题从主要基于风险的管理方法转变为基于可持续性的方法,以风险管理为基础的原则;3)健康,资源,成本,时间是最广泛使用的社会指标,环境,经济,和技术标准,分别;4)中国与其他国家存在明显差异,特别是在每个指标的使用频率上,社会标准的应用,和首选利益相关者。然而,中国已经取得了重大进展,现在在国际层面为可持续补救做出了越来越多的贡献。
    Sustainable remediation, which promotes the use of more sustainable practices during environmental clean-up activities, is an area of intense international development. While numerous indicators related to sustainable remediation assessment have been utilized and published in related academic literature, they are difficult to unify and vary in emphasis between countries. Following literature retrieval from CNKI, Springer, ScienceDirect, and Wiley Online databases, we present a systematic and bibliometric analysis of relevant national and international literature to define the most frequently considered indicators of sustainability, which play important roles in selecting remediation technologies or site management methods from a sustainability perspective. Following the application of co-occurrence analysis and social network analysis, the results indicate that 1) environmental criteria are most commonly used in evaluating remediation technologies, with significantly less emphasis on social criteria in Chinese publications in particular; 2) with an increasing number of publications in the last 20 years, sustainable remediation has gone through an initial stage, rising stage, and burst or wider adoption stage, characterized by a transformation of the research theme from a predominantly risk-based management approach to a sustainability-based one, with risk management as an underpinning principle; 3) health, resource, cost, and time are the most widely used indicators in terms of social, environmental, economic, and technical criteria, respectively; 4) clear differences exist between China and other nations, particularly in the frequency of usage of each indicator, the application of social criteria, and preferred stakeholders. Nevertheless, China has made significant progress and now makes increasing contributions to sustainable remediation at an international level.
