In organizations that manufacture products or provide services as well as in academic practice, the visualization of management systems’ standards is presented primarily in the form of static diagrams or tables. Demands for the quality of products and services are reflected in the complexity and interconnectedness of standards, which could cause complications during the implementation phase. This article presents a visualization of the standard IATF 16949 Automotive Quality Management System Standard, Quality management system requirements for automotive production and relevant service parts organizations, which incorporates in its content ISO 9001 Quality Management Systems—Requirements using a dynamic cluster model built using software TouchGraph Navigator. The visualization process began with a detailed examination of the two-stage requirements, documented information, and notes detailed in IATF 16949 and continued with the creation of a central node to which new nodes were subsequently connected, containing the introductory parts of the standard, including clauses. The activation of clauses and sub-clauses for other parts of the document followed. The dynamic behavior of the resulting cluster can be used in the implementation, execution, maintenance, or certification process to encourage organizations to improve their operational processes by incorporating more rigorous quality considerations into their operational frameworks.
在制造产品或提供服务的组织以及学术实践中,管理系统标准的可视化主要以静态图表或表格的形式呈现。对产品和服务质量的要求反映在标准的复杂性和相互关联性上,这可能在实施阶段造成复杂性。本文介绍了IATF 16949汽车质量管理体系标准的可视化,汽车生产和相关服务部件组织的质量管理体系要求,其内容包含ISO 9001质量管理体系要求,使用使用TouchGraph Navigator软件构建的动态集群模型。可视化过程从详细检查IATF 16949中的两阶段要求、文件化信息和注释开始,并继续创建中心节点,随后连接新节点,其中包含标准的介绍部分,包括条款。随后,文件其他部分的条款和分条款也被激活。结果集群的动态行为可用于实现、执行、维护或认证过程,以鼓励组织通过将更严格的质量考虑纳入其操作框架来改进其操作过程。

Flood–Ebb and Discharge Variations in Observed Salinity and Suspended Sediment in a Mesotidal Estuary 中潮汐口观测盐度和悬沙的涨潮和流量变化

To explore the spatial and temporal variations in salinity and suspended-sediment concentration in the Danshuei River estuary of northern Taiwan, two intensive field surveys were conducted in July 2016 and 2019 to assign high- and low-flow conditions, respectively. According to the analysis of tidal characteristics, the duration during ebb tide was longer than that during flood tide, while the maximum ebb discharge was higher than the maximum flood discharge, causing the occurrence of tidal asymmetry during ebb and flood tides. The barotropic forcing dominated during high flow, resulting in lower salinity and a shorter distance of saltwater intrusion. Based on the analyzed results using stratification indices, most of the time was spent in the state of partial mixing at the Guandu Bridge and good mixing at the Taipei Bridge during high flow, while most of the time was spent in the states of partial mixing and good mixing at both Guandu Bridge and Taipei Bridge during low flow. More stratification occurred during high flow at high slack tide compared to that during low flow. The freshwater discharges from upriver reaches controlled the suspended-sediment concentration (SSC) in tidal estuaries. The higher SSC appeared downstream of the tidal estuary at ebb tide during high flow. Observations also revealed that there was an estuarine turbidity maximum at the bottom layer of Guandu Bridge.
为探讨台湾北部丹水河口盐度和悬沙浓度的时空变化特征,于2016年7月和2019年7月进行了两次密集野外调查,分别设定了高流量和低流量条件。潮汐特征分析表明,退潮持续时间比涨潮持续时间长,而最大退潮流量大于最大洪流量,导致退潮和涨潮期间出现潮汐不对称现象。高流期以正压强迫为主,盐度较低,盐水侵入距离较短。根据分层指标分析结果,官渡桥高流量时大部分时间处于部分混合和良好混合状态,官渡桥和台北桥低流量时大部分时间处于部分混合和良好混合状态。高淡潮时高流量时分层现象较低流量时多。上游淡水排放控制了潮汐河口的悬沙浓度。大潮期退潮时,高SSC出现在潮口下游。观测还发现,官渡桥底层存在河口浊度最大值。

Ensuring the Validity of the Results by Participating in ILC Schemes—Case Study: The Determination of the Water-Soluble Chromium (VI) Content of Cement 通过参与ILC计划来确保结果的有效性——案例研究:水泥中水溶性铬(VI)含量的测定

The paper presents the mode in which an accredited laboratory, according to SR EN ISO/IEC 17025, monitors its performance by comparing the results with the results of other laboratories. This article aims to analyse the results of the participation of an accredited laboratory in two ILC schemes, one organized in France and the other in Romania, on cement, discussing only the results of the determinations of the water-soluble hexavalent chromium content. Although chromium (VI) is not present in large amounts in cement, it is responsible for allergic reactions on the skin of workers. Thus, in EU countries, the maximum amount of water-soluble Cr (VI) in bagged cement or in the products based on cement is limited to a maximum of 0.0002% by mass of cement. The Chromium (VI) results obtained by the lab must meet the requirements of the standard SR EN 196-10 for the repeatability and, where appropriate, the reproducibility. Questions about the validity of the results arise when the laboratory obtains satisfactory results in the ILC scheme, but the standard deviation of the scheme is higher than that recommended in the standard method. The elements of the novelty of this paper are the interpretation of water-soluble Cr (VI) results and the use of information obtained from participating in interlaboratory testing schemes tom improve the validity of laboratory results.
本文介绍了根据SR EN ISO/ iec17025认证的实验室通过与其他实验室的结果进行比较来监测其绩效的模式。本文旨在分析一个认可的实验室参与两个ILC计划的结果,一个在法国组织,另一个在罗马尼亚组织,关于水泥,只讨论水溶性六价铬含量的测定结果。虽然铬(VI)在水泥中不存在大量,但它是工人皮肤过敏反应的原因。因此,在欧盟国家,袋装水泥或基于水泥的产品中水溶性Cr (VI)的最大含量限制在水泥质量的0.0002%。实验室获得的铬(VI)结果必须符合标准SR EN 196-10的重复性要求,并且在适当的情况下,可再现性。当实验室在ILC方案中获得满意的结果时,会对结果的有效性产生质疑,但该方案的标准差高于标准方法中推荐的标准偏差。本文的新颖之处在于对水溶性Cr (VI)结果的解释,以及利用参与实验室间测试方案获得的信息来提高实验室结果的有效性。

Background: The performance assessment of tests that express qualitative results in the medical laboratory is of primary importance in characterization, diagnosis, follow-up, and screening. An important contribution to this type of assessment may be the publication of the Eurachem AQA 2021 guide. The text intends to principally discuss the consistency of the subclauses of this guide with ISO 15189 and CLSI EP12-A2. Methods: The study involves a literature review within the scope of qualitative tests. Results: Tables are used for crossing AQA. with ISO 15189 and CLSI EP12-A2. Conclusions: Consistency with ISO 15189 and CLSI EP12-A2 is demonstrated in the study. Introducing “uncertainty of proportion” reflects the necessity of assessing uncertainties when dealing with qualitative results.

Standards and Assessment of Construction Products: Case Study of Ceramic Tile Adhesives 建筑产品标准与评价:以瓷砖胶粘剂为例
Pub Date : 2022-05-07 DOI: 10.3390/standards2020013

This work attempts to draw attention to the importance of a multidimensional approach when creating standard requirements in the assessment of construction products with the example of ceramic tile adhesives (CTAs). CTAs are an essential group of building materials today, the continuous development of which has been noted since the 1960s. However, until 2001, i.e., the year when EN 12004 was published, there were no precise requirements for CTAs at the European level, which often made it difficult or, in extreme cases, even impossible to assess the product objectively. Under the provisions of EN 12004, for twenty years, the basis for the assessment and verification of constancy of performance (AVCP) of CTAs has been adhesion determined by tensile strength. The paper discusses the test methods, paying attention to their imperfections, including the impact of the materials used in measurements, i.e., concrete slab, ceramic tile, and water quality. The results of the multi-annual interlaboratory tests indicate that an essential factor that must be considered in the process of AVCP is test measurement uncertainty. Additionally, it should be remembered that uncertainty also occurs at other assessment levels. It also seems that the simple acceptance rule that does not consider the variability resulting from the measurement uncertainty is inadequate when assessing CTAs.
这项工作试图以瓷砖粘合剂(cta)为例,在建筑产品评估中创建标准要求时,引起人们对多维方法重要性的关注。cta是当今一种重要的建筑材料,自20世纪60年代以来一直在不断发展。然而,直到2001年,即EN 12004发布的那一年,在欧洲层面上没有对cta的精确要求,这往往使得很难或在极端情况下,甚至不可能客观评估产品。根据EN 12004的规定,二十年来,cta的性能稳定性(AVCP)的评估和验证的基础是由拉伸强度决定的附着力。本文讨论了测试方法,并注意了它们的缺陷,包括测量所用材料的影响,即混凝土板,瓷砖和水质。多年实验室间试验结果表明,在AVCP过程中必须考虑的一个重要因素是试验测量不确定度。此外,应该记住,不确定性也发生在其他评估级别。在评估cta时,不考虑由测量不确定度引起的可变性的简单接受规则似乎也不充分。

Technologies and systems for indoor positioning, mapping, and navigation (IPMN) have rapidly developed over the latest decade due to advanced radio and light communications, the internet of things, intelligent and smart devices, big data, and so forth. Thus, a group of surveys for IPMN technologies, systems, standards, and solutions can be found in literature. However, currently there is no proposed solution that can satisfy all indoor application requirements; one of the biggest challenges is lack of standardization, even though several IPMN standards have been published by different standard developing organizations (SDOs). Therefore, this paper aims to re-survey indoor positioning and mapping technologies, in particular, the existing standards related to these technologies and to present guidance in the field. As part of our work, we provide an IPMN standards system architecture consisting of concepts, terms, models, indoor positioning technologies, software and tools, applications, services and policies, and indoor mapping and modelling; and, we present IPMN standards developed for our projects in practice, such as multi-source fusion positioning data interfaces; seamless cooperative positioning service interfaces; content model for indoor mapping and navigation, and specification for digital indoor map products.
近十年来,由于先进的无线电和光通信、物联网、智能和智能设备、大数据等技术的发展,室内定位、测绘和导航(IPMN)技术和系统得到了迅速发展。因此,可以在文献中找到一组关于IPMN技术、系统、标准和解决方案的调查。然而,目前还没有提出能够满足所有室内应用要求的解决方案;尽管不同的标准开发组织(sdo)已经发布了几个IPMN标准,但最大的挑战之一是缺乏标准化。因此,本文旨在对室内定位与测绘技术,特别是与这些技术相关的现有标准进行重新调查,并提出该领域的指导意见。作为我们工作的一部分,我们提供了一个IPMN标准体系架构,包括概念、术语、模型、室内定位技术、软件和工具、应用程序、服务和政策,以及室内制图和建模;并且,我们提出了在实践中为我们的项目开发的IPMN标准,如多源融合定位数据接口;无缝协同定位服务接口;室内地图导航内容模型及室内数字地图产品规范。

Evaluating Management Practices in Precision Agriculture for Maize Yield with Spatial Econometrics 用空间计量经济学评价玉米产量的精准农业管理实践

Precision agriculture (PA) aims to provide data on soil, nutrient use, irrigation, and crops, to guide management strategic decisions towards an efficient use of inputs, increasing production and avoiding environmental problems due to excessive accumulation of fertilizers. In this paper, PA data from a large Portuguese farm producing maize were used to assess the effectiveness of agronomic management decisions concerning fertilizer and nutrient use, seed choice, and water content, in terms of crop productivity. The maize yield in 2017 and 2018 was modelled as a function of manageable inputs and unmanageable factors introduced as control variables. Panel spatial econometric methods were used for specification and estimation, to control for spatial dependence and spatial heterogeneity. The model proved to fit the data remarkably well and could be a good reference for specifying models to explain maize production; thus, helping researchers who need to deal with the huge amount of data that normally originates from PA. Additionally, it can be considered another tool for farm managers, helping in the design and evaluation of their agronomic management decisions.
精准农业(PA)旨在提供关于土壤、养分利用、灌溉和作物的数据,以指导管理战略决策,以有效利用投入、增加产量和避免因肥料过度积累而造成的环境问题。本文利用葡萄牙一家大型玉米农场的PA数据,评估了有关肥料和养分使用、种子选择和水分含量的农艺管理决策在作物生产力方面的有效性。将2017年和2018年玉米产量建模为可控投入和不可控制因素作为控制变量的函数。面板空间计量经济学方法用于规范和估计,以控制空间依赖性和空间异质性。结果表明,该模型具有较好的拟合效果,可为玉米生产模型的确定提供参考;因此,帮助需要处理通常来自PA的大量数据的研究人员。此外,它可以被认为是农场管理者的另一种工具,有助于设计和评估他们的农艺管理决策。

In recent years, the concept of quality has asserted growing interest, especially among enterprises, aiming to promote consumers by creating distinctive marks. In Italy, in 2021, the number of filled quality trademarks for products and services will amount to about 81. Through the “Decreto Crescita”, Italy supported Italian companies to limit their delocalization overseas. In this regard, the historical mark of national interest was established, from which Italian companies with a trademark filed for at least 50 years can benefit. Therefore, the study aimed at evaluating two different types of trademarks, quality marks and historical marks, highlighting the main aspects that characterize these two marks as a function of the standards that distinguish them from the most common trademarks. For this purpose, the study focused on evaluating historical brands in Italy to promote their strategic importance and enhance the temporal continuity of the marks. These were considered a new marketing tool to promote know-how and “Made in Italy”, which is particularly useful for the brand image of companies to be competitive in a global market.
商标是一种独特的标志,旨在推广和提高公司的产品/服务。近年来,质量的概念越来越受到关注,特别是在企业中,旨在通过创造独特的标志来吸引消费者。在意大利,到2021年,产品和服务的质量商标数量将达到81个左右。通过“Crescita法令”,意大利支持本国公司限制其海外本地化。在这方面,建立了具有国家利益的历史标志,拥有至少50年商标申请的意大利公司可以从中受益。因此,本研究旨在对质量商标和历史商标这两种不同类型的商标进行评价,并突出这两种商标的主要特征,以及区分它们与最常见商标的标准的功能。为此,本研究侧重于对意大利历史品牌进行评估,以促进其战略重要性并增强商标的时间连续性。这被认为是一种新的营销工具,可以促进专有技术和“意大利制造”,这对公司在全球市场上具有竞争力的品牌形象特别有用。

Environmental justice (EJ) is a broad discipline that attempts to understand and redress unfair exposure to unhealthy environmental conditions. EJ is often made measurable with indicators, however the capabilities and the limitations of EJ indicators can be difficult for policy makers to understand. Using an exploratory review of EJ literature, this paper performs a research translation role by clarifying the key terms used to describe EJ indicators and by providing conceptual frameworks for developing locally valid EJ indicators for government and community. Issues such as the position of EJ in the context of the social determinants of health, indicator development, and definitions are explored. The exploratory literature review highlighted the potential and limitations of EJ indicators for measuring the extent and impact of EJ issues on human health and the environment. We found that EJ indicators are invariably (1) composed of two or more measures, and (2) developed iteratively, in consultation with those affected. To aid governments and communities, we present both a top-down and a bottom-up framework for developing EJ indicators, with the bottom-up framework guiding the combination of measures from four different core elements; environment, demography, epidemiology and procedures. A list of evidence-based example measures, from the literature, for developing EJ indicators is also provided. It is anticipated that the frameworks and list of EJ example measures will provide guidance for efficiently developing locally relevant EJ indicators.
环境正义(EJ)是一门广泛的学科,试图理解和纠正不健康环境条件下的不公平暴露。EJ通常是用指标来衡量的,然而EJ指标的能力和局限性对政策制定者来说很难理解。本文通过对EJ文献的探索性回顾,明确了描述EJ指标的关键术语,并为政府和社区制定当地有效的EJ指标提供了概念框架,从而发挥了研究翻译的作用。在健康的社会决定因素、指标制定和定义的背景下,探讨了诸如EJ的地位等问题。探索性文献综述强调了EJ指标在衡量EJ问题对人类健康和环境的程度和影响方面的潜力和局限性。我们发现EJ指标总是(1)由两个或更多的措施组成,(2)在与受影响的人协商的情况下迭代地发展。为了帮助政府和社区,我们提出了一个自上而下和自下而上的框架来制定EJ指标,其中自下而上的框架指导了四个不同核心要素的措施组合;环境,人口,流行病学和程序。还提供了一份基于证据的例子措施清单,这些措施来自文献,用于制定EJ指标。预计这些框架和范例措施清单将为有效制定当地相关的环境保护指标提供指导。
