    最近的海上网络安全事故表明,航运正面临越来越多的网络威胁,特别是由于该行业的数字化快速增长,使船只及其船上系统容易受到网络攻击。这项研究旨在评估影响海事行业网络安全绩效的关键维度之间的关系。为了实现这一点,首先通过文献综述确定了与网络安全准备相关的六个关键维度,即“法规”,从管理角度来看,“公司程序”和“船上系统准备情况”,“培训和意识”,操作级别的\'人为因素\'和\'合规性监视\'。设计了Likert量表问卷,用于收集133名海员和岸上工作人员的经验数据。结构方程建模(SEM)用于检验六个维度与船上网络安全性能之间的因果关系。结果表明,“法规”对航运公司“与网络安全相关的程序”产生积极影响,这反过来又会积极影响“船上系统的准备情况”,“培训和意识”,和\'监视\'。Further,“培训和意识”对船舶的网络安全性能产生积极影响。结果对航运业如何加强其网络实践以提高其网络安全性能具有深远的意义。还提供了与海上网络安全有关的未来学术研究的建议。
    Recent maritime cybersecurity accidents reveal that shipping is facing increased exposure to cyber threats, especially due to the fast-growing digitalisation of the sector, leaving vessels and their onboard systems vulnerable to cyberattacks. This research aims at evaluating the relationship among the critical dimensions influencing cybersecurity performance in the maritime industry. To achieve this, six critical dimensions related to cybersecurity preparedness are first identified through literature review, namely \'regulations\', \'company procedures\' from a managerial perspective and \'shipboard systems readiness\', \'training and awareness\', \'human factor\' and \'compliance monitoring\' at an operation level. A Likert-scale questionnaire is designed and used to collect empirical data from 133 seafarers and shore-based staff. Structural Equation Modelling (SEM) is applied to examine the causal relationships between the six dimensions and shipboard cybersecurity performance. The results show that \'regulations\' positively influence shipping companies\' cybersecurity-related \'procedures\', which in turn positively affects \'shipboard systems readiness\', \'training and awareness\', and \'monitoring\'. Further, \'training and awareness\' positively influences the cybersecurity performance of ships. The results have profound implications for the shipping industry on how to strengthen their cyber practices in order to improve their cybersecurity performance. Recommendations for future academic research related to maritime cybersecurity are also provided.

    人类状况与执行的任何活动中的错误有关,医疗保健世界也不例外。人类错误的起源不在于人性的反常,相反,它起源于医疗保健环境中的潜在失败,并且是所应用的过程和程序的结果。人为因素科学涉及将知识应用于人们(能力,特点和局限性),他们使用的设备的设计和管理,以及他们工作的环境和他们开展的活动。人为因素的一部分是非技术技能。这些技能极大地影响人们的行为和,因此,他们在非常复杂的社会技术系统中的表现和医疗保健质量。
    The human condition is linked to error in any activity that is performed, and the healthcare world is no exception. The origin of human error does not lie within the perversity of human nature, instead, it has its origins in latent failures in the healthcare environment and is a consequence of the processes and procedures applied. The science of the Human Factor deals with the application of knowledge to people (capabilities, characteristics and limitations), with the design and the management of the equipment they use and with the environments in which they work and the activities they carry out. Part of the Human Factor are the non-technical skills. These skills greatly influence people\'s behavior and, therefore, their performance and the quality of healthcare in a very complex socio-technical system.

    本文以中国云南省的少数民族村寨,具有多民族融合的显著特点,作为研究对象。通过各种空间统计分析方法,分析了云南民族村寨的总体分布特征,各民族之间的分布差异,分布格局的影响因素。研究发现:(1)云南少数民族村寨普遍表现出“三个集中区域,多个分散点”的内核密度特征和“西部热点,东部冷点”的分布特征。每个民族都有一个相对集中的区域,呈现显著的种族自相关。(2)各民族之间村庄与景观关系的差异,产生了独特的三维分布格局,这与民族血统和生计文化有关。同时,汉族传统村落往往占据地理条件相对较好的地区。(3)自然因素,如地形起伏,民族村庄和河流之间的距离,和海拔,对云南民族村寨的分布有显著影响。同时,社会和人为因素的测试结果,包括与中心城市的距离,人均GDP,第一产业年总产值,表明社会经济的发展和城市化的推进对民族村寨的保护提出了挑战。
    This paper takes ethnic minority villages in Yunnan province of China, which have significant characteristics of multi-ethnic integration, as the research object. Through various spatial statistical analysis methods, we analyzed the overall distribution characteristics of ethnic villages in Yunnan, the distribution difference among various ethnic groups, and the influencing factors of the distribution pattern. It was found that: (1) The ethnic minority villages in Yunnan generally exhibit a kernel density characteristic of \"three concentrated areas and multiple scattered points\" and distribution characteristic of \"hot spots in the west and cold spots in the east\". Each ethnic group has a relatively concentrated region, presenting significant ethnic autocorrelation. (2) The differences in the relationship between villages and landscape among various ethnic groups have given rise to a unique three-dimensional distribution pattern, which is relate to ethnic origin and livelihood culture. Meanwhile, Han traditional villages tend to occupy areas with relatively better geographical conditions. (3) Natural factors, such as topographic relief, the distance between ethnic villages and rivers, and elevation, have a significant impact on the distribution of ethnic villages in Yunnan. Meanwhile, test results of social and human factors, including the distance from central cities, per capita GDP, and the gross annual output values of primary industry, indicate that the development of social economy and the promotion of urbanization pose challenges to the preservation of ethnic villages.

    背景:生物制药是复杂的生物分子,需要仔细的储存和处理以确保药物的完整性。在这项研究中,对现实世界的蛋白质药物(PD)处理进行了工作系统分析,目标如下:确定成功遵守PD处理中公认建议的主要障碍和促进因素,分析两个组织的差异,并根据工作系统分析的结果,在实际处理PD中定义最佳当前实践。
    方法:在西班牙和瑞典的两家大学医院进行的观察性研究。基于患者安全系统工程计划(SEIPS)模型,选择的工具是:PETT扫描,为了表明PETT组件(人,环境,工具,Tasks);Tasksandtoolsmatrixtoconstructachecklisttorecorddirectobservationsduringthereal-lifehandlingofbiopharmaceuticals,和旅程地图来描绘工作过程。在2022年3月至11月之间进行了观察。每集的直接观察包括一个单一的蛋白质药物在供应链的某个点,并考虑了工作系统中的所有元素。根据工作系统分析和文献综述的结果,作者提出了一个项目列表,这些项目可以被认为是在医院中处理PDs的最佳当前实践.
    结果:共有34个观察,涉及19个PD。关于参与工作过程的人,有各种各样的专业人士,他们以前的培训和知识不同,导致信息鸿沟。关于环境,医院之间的一些结构和组织差异导致与PD暴露于室温和机械应力的时间相关的风险.该过程中涉及的工具和任务也存在一些差异,尤其与PD缺乏与新技术的兼容性信息有关,如气动管系统,机器人重组或封闭系统转移设备。最后,提出了15条关于当前最佳实践的建议。
    结论:发现的遵守公认建议的主要障碍与参与处理蛋白质药物的专业人员发现的信息差距有关,不受监测的温度以及缺乏蛋白质药物与一些新技术的相容性信息。通过应用人为因素和系统工程方法,通过对两家欧洲医院的比较,得出了在一家医院中处理蛋白质药物的最佳实践列表.
    Biopharmaceuticals are complex biological molecules that require careful storage and handling to ensure medication integrity. In this study, a work system analysis of real-world protein drug (PD) handling was performed with the following goals: identify main barriers and facilitators for successful adherence to accepted recommendations in PD handling, analyse differences in two organizations, and define a Best Current Practice in the real-life handling of PDs based on the results of the work system analysis. Observational study was held in two university hospitals in Spain and Sweden. Based on the Systems Engineering Initiative for Patient Safety (SEIPS) model, the tools chosen were: the PETT scan, in order to indicate the presence of barriers or facilitators for the PETT components (People, Environment, Tools, Tasks); the Tasks and tools matrices to construct a checklist to record direct observations during the real-life handling of biopharmaceuticals, and the Journey map to depict the work process. Observations were performed between March and November 2022. Each episode of direct observation included a single protein drug in some point of the supply chain and considered all the elements in the work system. Based on the results of the work system analysis and the literature review, the authors propose a list of items which could be assumed as Best Current Practice for PDs handling in hospitals. There were a total of 34 observations involving 19 PDs. Regarding People involved in the work process, there was a diversity of professionals with different previous training and knowledge, leading to an information gap. With respect to Environment, some structural and organizational differences between hospitals lead to risks related to the time exposure of PDs to room temperature and mechanical stress. Some differences also existed in the Tools and Tasks involved in the process, being especially relevant to the lack of compatibility information of PDs with new technologies, such as pneumatic tube system, robotic reconstitution, or closed-system transfer devices. Finally, 15 suggestions for best current practice are proposed. Main barriers found for compliance with accepted recommendations were related to the information gap detected in professionals involved in the handling of protein drugs, unmonitored temperature, and the lack of compatibility information of protein drugs with some new technologies. By applying a Human Factors and Systems Engineering Approach, the comparison of two European hospitals has led to a suggested list of Best Current Practices in the handling of protein drugs in a hospital.

    PFS的发展需要详细了解药物管理过程中发生的力量和患者的能力。这项研究描述了一种先进的数学注射力模型,该模型由流体动力和摩擦力组成。流体动力遵循Hagen-Poiseuille的基本定律,但通过深入研究药物粘度(牛顿和剪切稀化)和注射器形状常数的特定特性来完善建模方法,而摩擦力来自空筒注射力。此外,我们考虑注射的实际温度,提供更准确的预测。结果表明,针尺寸常数的推导和蛋白质溶液的流变行为是关键参数。此外,由组织产生的反压力已被认为在实际管理,以解决在空气中进行的当前注射力评估的不准确性的问题,特别是当注射的药物溶液的粘度低于9.0cP时(用29G½英寸针头用1mLLPFS注射)。对患者抗药物粘度能力的人为因素研究填补了PFS药物产品设计空间和早期可用粘度数据的空白。
    The development of PFS requires a detailed understanding of the forces occurring during the drug administration process and patient\'s capability. This research describes an advanced mathematic injection force model that consisting hydrodynamic force and friction force. The hydrodynamic force follows the basic law of Hagen-Poiseuille but refines the modeling approach by delving into specific properties of drug viscosity (Newtonian and Shear-thinning) and syringe shape constant, while the friction force was accounted from empty barrel injection force. Additionally, we take actual temperature of injection into consideration, providing more accurate predication. The results show that the derivation of the needle dimension constant and the rheological behavior of the protein solutions are critical parameters. Also, the counter pressure generated by the tissue has been considered in actual administration to address the issue of the inaccuracies of current injection force evaluation preformed in air, especially when the viscosity of the injected drug solution is below 9.0 cP (injecting with 1 mL L PFS staked with 29G ½ inch needle). Human factor studies on patients\' capability against medication viscosity filled the gap in design space of PFS drug product and available viscosity data in very early phase.

    Vegetation plays a critical role in the water and carbon cycling and energy flow, serving as an indicator for regulating land carbon balance and reflecting climate change and human activities. We analyzed the spatiotemporal variations of normalized difference vegetation index (NDVI) during the growing season in southern Jiangxi from 2000 to 2020, using statistical methods, including the Mann-Kendall test, Theil-Sen Median analysis, Hurst index, and coefficient of variation. We employed the geodetector model to comprehensively assess the impacts of climate, topography, soil and human factors on spatial differentiation of vegetation NDVI. The results showed NDVI exhibited an upward fluctuating trend with a rate of 0.003 per year from 2000 to 2020. The proportion of high-grade and medium-high-grade NDVI areas were 55.8% and 41.9%, respectively, while the areas with low and relatively low fluctuations accounted for 92.3%. The proportions of areas showing extremely significant improvement and significant improvement were 40.4% and 19.4%, respectively. In contrast, the combined proportion of areas displaying extremely significant degradation and significant degradation was only 2.2%. The proportions of areas demonstrating continuous improvement and future improvement were 28.0% and 60.2%, respectively. Elevation, precipitation, relative humidity, temperature, landform type, land use type, population density, and nighttime light were identified as the major factors for the vairations of NDVI in the study area, followed by slope, soil type, and GDP, while slope aspect and vegetation type had indirect influence. Throughout the study period, NDVI in southern Jiangxi was overall stable, with future changes primarily indicating improvement. Notably, human factors such as land use type, population density, and nighttime light index exhibited an upward trend in their impacts on NDVI.

    背景:探索宏基因组重叠群并将它们“分类”为宏基因组组装的基因组(MAG)对于划定微生物群落中的功能和进化行会至关重要。尽管自动装箱算法取得了进展,到目前为止,他们在恢复具有准确性和生物学相关性的MAG方面的能力是有限的。研究人员经常发现,人为参与对于实现代表性的分箱结果是必要的。然而,这种手动过程需要专业知识和劳动密集型,它应该得到软件基础设施的支持。
    结果:我们介绍BinaRena,一个全面而通用的图形界面,致力于帮助人类操作员通过可定制的可视化来探索宏基因组组件,并将重叠群与垃圾箱相关联。根据各种数据类型,将连续图形呈现为交互式散点图,包括序列度量,覆盖范围概况,分类学分配,和功能注释。允许各种重叠群级别的操作,比如选择,掩蔽,突出显示,聚焦,和搜索。装订计划可以方便地编辑,检查,并在视觉上或使用包括轮廓系数和调整后的兰德指数在内的指标进行比较。可以实时计算用户选择的重叠群的完整性和污染。在演示BinaRena\的可用性时,我们证明它促进了生物模式的发现,假设生成,在一个复杂的热带泥炭地宏基因组中进行bin精炼。它能够从腹泻人类受试者的肠道微生物群中分离密切相关群体中的致病基因组。在使用模拟海洋数据集整理自动装仓器的结果后,它显着提高了整体装仓质量。
    结论:BinaRena是一个免安装的,无依赖,客户端Web应用程序,可直接在任何现代Web浏览器中运行,为所有技能水平的研究人员提供易于部署和可访问性。该程序托管在https://github.com/qiyunlab/binarena,连同文档,教程,示例数据,和现场演示。它有效地支持人类研究人员对宏基因组数据的直观解释和微调。视频摘要。
    Exploring metagenomic contigs and \"binning\" them into metagenome-assembled genomes (MAGs) are essential for the delineation of functional and evolutionary guilds within microbial communities. Despite the advances in automated binning algorithms, their capabilities in recovering MAGs with accuracy and biological relevance are so far limited. Researchers often find that human involvement is necessary to achieve representative binning results. This manual process however is expertise demanding and labor intensive, and it deserves to be supported by software infrastructure.
    We present BinaRena, a comprehensive and versatile graphic interface dedicated to aiding human operators to explore metagenome assemblies via customizable visualization and to associate contigs with bins. Contigs are rendered as an interactive scatter plot based on various data types, including sequence metrics, coverage profiles, taxonomic assignments, and functional annotations. Various contig-level operations are permitted, such as selection, masking, highlighting, focusing, and searching. Binning plans can be conveniently edited, inspected, and compared visually or using metrics including silhouette coefficient and adjusted Rand index. Completeness and contamination of user-selected contigs can be calculated in real time. In demonstration of BinaRena\'s usability, we show that it facilitated biological pattern discovery, hypothesis generation, and bin refinement in a complex tropical peatland metagenome. It enabled isolation of pathogenic genomes within closely related populations from the gut microbiota of diarrheal human subjects. It significantly improved overall binning quality after curating results of automated binners using a simulated marine dataset.
    BinaRena is an installation-free, dependency-free, client-end web application that operates directly in any modern web browser, facilitating ease of deployment and accessibility for researchers of all skill levels. The program is hosted at https://github.com/qiyunlab/binarena , together with documentation, tutorials, example data, and a live demo. It effectively supports human researchers in intuitive interpretation and fine tuning of metagenomic data. Video Abstract.
