In this paper we present a study aimed at distinguishing elderly (over 65 years) and young (under 25) participants in driving environment by observing solely their eye movements. Selected groups of elderly and young drivers were asked to drive 30 km on suburban, urban and regional roads in a high-fidelity motion-based driving simulator. During the drive their gaze behaviour and eye movements were recorded using the Tobii Pro Glasses 2 eye tracker, providing data on gaze position, blink rate and pupil size. The data was processed with the PyGaze library, which was adapted to be compatible with the Tobii Pro data output format. In the next step, a decision tree-based binary classification method was applied to distinguish between the two age groups based solely on their eye movements and pupillary responses. The machine learning approach showed an overall accuracy of 0.8 which means that eye tracking data can be a very good predictor of driver’s age in a driving environment.
在本文中,我们提出了一项研究,旨在通过观察老年人(65岁以上)和年轻人(25岁以下)在驾驶环境中的眼球运动来区分他们。经过挑选的老年人和年轻人驾驶组被要求在一个高保真的基于动作的驾驶模拟器中在郊区、城市和地区道路上行驶30公里。在驾驶过程中,研究人员使用Tobii Pro Glasses 2眼动仪记录了他们的凝视行为和眼球运动,提供了凝视位置、眨眼频率和瞳孔大小的数据。使用PyGaze库处理数据,该库经过调整以与Tobii Pro数据输出格式兼容。下一步,采用基于决策树的二值分类方法,仅根据他们的眼球运动和瞳孔反应来区分两个年龄组。机器学习方法的总体精度为0.8,这意味着眼动追踪数据可以很好地预测驾驶环境中驾驶员的年龄。

According to the World Health Organization (WHO), over 1 billion people are overweight and 600 million are obese, with metabolic syndrome (MS) affecting 35% of adults in the US and 20-25% in Europe. MS patients require appropriate therapy with comorbidity in mind, which requires further study and optimization. As part of the study, we conducted Holter ECG monitoring (HM) of patients with MS. MS was diagnosed on the basis of the MTP 3rd revision criteria. Additional criteria were AH, elevated triglyceride levels, decreased HDL cholesterol levels, impaired glucose tolerance (IGT), impaired fasting glycemia (EGS), and combined EGS/IGT disorders. MS was diagnosed based on 3 criteria: 1 main and 2 additional ones.Design. A total of 154 patients were examined in in-patient setting. They were subdivided into 2 main groups: Group I - patients with MS receiving β-blockers (n-97) to treat AH; Group II - patients with MS not receiving β-blockers (n-57).Each main group was divided according to the degree of obesity according to the WHO classification. Each patient underwent HM with programmed computer analysis of the wave spectrum of the obtained data and allocation of frequencies - 0.004-0.08 Hz (very low frequency - VLF); 0.09-0.16 Hz (low frequency - LF); 0.17-0.5 Hz (high frequency - HF) more than 0.5 Hz (ultra-low frequency waves - ULF); two coefficients are calculated - LF/HF (vagosympathetic balance coefficient) - ratio of low frequency waves power (LF) to high frequency waves power (HF), and centralization index (CI) - ratio of central regulation circuit activity to autonomic one (LF+VLF/HF).Results. Analysis found changes in HF, LF, and ULF domains of HRV spectrum, indicating transition to a more energy-intensive level of control and depletion of regulatory mechanisms. ULF(%) values above 6.9 require correction with β-blockers. The study found ULF% and VLF% values to be higher in the non-β-blocker group and administration of β-blockers resulted in normalization of indexes with the index of centralization and vagosympathetic balance. In patients receiving β-blockers, the values of these parameters corresponded to those of patients with normal body weight. In MS patients not receiving β-blockers, ULF% was 50% higher and VLF was 18% higher than in the normal weight group. The centralization index was elevated to 3.5. Administration of drugs to 17 patients in group II resulted in normalization of the indexes and achievement of the same values as in group I patients. At the dynamic follow-up for 2 years, Group I patients had no cardiovascular events. The 40 patients who refused to change therapy had no change in HM values and 27% of these patients had acute cardiovascular events at 2 years.Conclusion:Daily ECG monitoring with assessment of ULF%, VLF% and IC indices is a more subtle method of investigation, which allows to detect latent disorders of regulatory mechanisms (with seeming clinical well-being) in patients with disorders of these indices the ri
根据世界卫生组织(WHO)的数据,超过10亿人超重,6亿人肥胖,代谢综合征(MS)影响了35%的美国成年人,20-25%的欧洲成年人。MS患者需要考虑合并症的适当治疗,这需要进一步的研究和优化。作为研究的一部分,我们对根据MTP第三版标准诊断的MS患者进行了动态心电图监测(HM)。其他标准包括AH、甘油三酯水平升高、高密度脂蛋白胆固醇水平降低、糖耐量(IGT)受损、空腹血糖(EGS)受损以及EGS/IGT合并紊乱。MS的诊断依据3项标准:1项主要标准和2项附加标准。共有154名患者在住院环境中接受了检查。他们被细分为2个主要组:第一组- MS患者接受β受体阻滞剂(n-97)治疗AH;II组:未接受β受体阻滞剂治疗的MS患者(n-57)。根据世界卫生组织的分类,将每个主要群体根据肥胖程度进行划分。每位患者都接受了HM,并对获得的数据的波谱进行了编程计算机分析和频率分配- 0.004-0.08 Hz(甚低频- VLF);0.09-0.16 Hz(低频- LF);0.17-0.5 Hz(高频- HF)以上0.5 Hz(超低频波- ULF);计算两个系数:迷走交感平衡系数LF/HF -低频波功率(LF)与高频波功率(HF)之比;集中化指数CI -中枢调节回路活动与自主回路活动之比(LF+VLF/HF)。分析发现,HRV谱的HF、LF和ULF结构域发生了变化,表明向能量密集型控制水平的转变和调节机制的枯竭。高于6.9的ULF(%)值需要用β受体阻滞剂校正。研究发现,非β受体阻滞剂组的ULF%和VLF%值较高,β受体阻滞剂的使用使迷走交感神经平衡指数和中枢指数恢复正常。在接受β受体阻滞剂治疗的患者中,这些参数的值与正常体重患者的值一致。在未接受β受体阻滞剂治疗的MS患者中,ULF%比正常体重组高50%,VLF高18%。集中化指数上升至3.5。II组17例患者用药后各项指标均恢复正常,达到与I组相同的值。动态随访2年,I组患者无心血管事件发生。拒绝改变治疗的40例患者HM值没有变化,其中27%的患者在2年时发生了急性心血管事件。结论:每日心电监测并评估ULF%、VLF%和IC指数是一种更精细的调查方法,可以发现潜在的调节机制障碍(表面上是临床健康),这些指标障碍的患者发生急性心血管事件的风险仍然很高。心电联用法对ULF%、VLF%及IC指标的控制,可以及时改变治疗方案,获得较好的效果。

Surgical adverse events can have serious consequences for patients ranging from temporary injuries to death. Thereby, up to 40% of surgical adverse events are preventable and over 60% of causal factors were found to be linked to human factors. To improve surgical performance and safety, computer-assisted surgical (CAS) systems can be used to reduce excessive workloads. This paper presents a method for prospective assessment of surgical task workloads. S-TAWL, developed with the support of a senior neurosurgeon and a usability engineer, consists of three parts: surgical task decomposition, workload rating scale application, and performance shaping factors characterization. For the proposed rating scales, composed of reference operators, relative workloads were determined by 11 neurosurgeons through pairwise comparison. Afterwards, one senior neurosurgeon, not involved in method development, analysed workloads of four common surgical tasks with the proposed method S-TAWL and a reference workload rating method Surg-TLX. Qualitatively, S-TAWL provides more detailed information about workloads with respect to human resources compared to the reference method. Quantitatively, however, the reliability of the results is still limited, as indicated by high standard deviations. Further research is needed to develop reliable and valid rating scales, compute compound workloads and identify overloads. Incorporating quantitative workload assessment in prospective human performance analysis will provide valuable information for targeted model-based design of assistance systems, supporting safe and successful surgery in the future.
手术不良事件可对患者造成严重后果,从暂时性损伤到死亡不等。因此,高达40%的手术不良事件是可以预防的,超过60%的原因被发现与人为因素有关。为了提高手术性能和安全性,可以使用计算机辅助手术(CAS)系统来减少过度的工作量。本文提出了一种对手术任务负荷进行前瞻性评估的方法。S-TAWL是在一名高级神经外科医生和一名可用性工程师的支持下开发的,由三部分组成:手术任务分解、工作量评定量表应用和性能塑造因素表征。对于由参考操作者组成的评分量表,由11名神经外科医生通过两两比较确定相对工作量。随后,一位未参与方法开发的高级神经外科医生使用提出的方法S-TAWL和参考工作量评定方法外科- tlx分析了四种常见手术任务的工作量。定性地说,与参考方法相比,S-TAWL提供了关于人力资源方面的工作负载的更详细信息。然而,从数量上讲,结果的可靠性仍然有限,这是由高标准偏差所表明的。需要进一步的研究来开发可靠和有效的评级量表,计算复合工作负载和识别过载。将定量工作量评估纳入前瞻性人类表现分析将为辅助系统的有针对性的基于模型的设计提供有价值的信息,支持未来安全成功的手术。

The construction industry has been one of the most hazardous and waste-generating industries in the United States for decades, due to the unique nature of work and high degree of organizational complexity on jobsites. A number of citations against OSHA (Occupational Safety and Health Administration) 29 CFR (Code of Federal Regulations) 1926 Safety and Health Regulations for Construction, primarily in sections that address fall protection and safety training in construction, appear in OSHA’s annual top 10 list of most frequently cited violations consistently. Innovative, science-based, and technology-driven solutions become more and more utilized in the construction industry. Examples of these solutions include: situated learning approach to improve the effectiveness of training, wearable technology to enhance personal protection, remote-controlled drones to perform various functions specially to improve site security, prevention through design concept to minimize risks, total worker health initiative to advance worker well-being, etc. It is imperative that safety, health, and environmental professionals should attempt to clearly understand the impact of these emerging technologies on construction safety and health, and be able to apply scientific principles to anticipate, identify, analyze, and control workplace hazards within the construction industry. Specifically, the pros and cons of each solution need to be examined and compared in order to identify effective methods to promote sustainable workforce and improve safety and health in construction.
几十年来,由于工作的独特性质和工地组织的高度复杂性,建筑行业一直是美国最危险和产生废物的行业之一。对OSHA(职业安全与健康管理局)29 CFR(联邦法规)1926年建筑安全与健康法规的大量引用,主要是在涉及建筑中的坠落保护和安全培训的部分,出现在OSHA年度十大最常被引用的违规行为名单中。创新、科学、技术驱动的解决方案越来越多地应用于建筑行业。这些解决方案的例子包括:情境学习方法,以提高培训的有效性;可穿戴技术,以加强个人保护;远程控制无人机,以执行各种功能,专门提高现场安全;通过设计理念预防,以尽量减少风险;全面工人健康倡议,以提高工人福祉等。安全、健康和环境专业人员必须尝试清楚地了解这些新兴技术对建筑安全和健康的影响,并能够应用科学原理来预测、识别、分析和控制建筑行业内的工作场所危害。具体而言,需要审查和比较每种解决方案的利弊,以便确定有效的方法,促进可持续的劳动力和改善建筑中的安全和健康。

Illuminating Narratives of Young Wheelchair Users: Lived Experience Insights for Framing Child-Centred Inclusive Mobility Design 年轻轮椅使用者的启发性叙述:构建以儿童为中心的包容性移动设计的生活体验见解

Lived experiences and individual interpretations of reality can be effectively communicated through narratives. As such, capturing and understanding narratives can be considered of critical importance in human-centred design, as they form the essence and perspective a design is built upon and are thus essentially embedded into the designed outcome. The role of narratives in design becomes particularly critical when designing with or for end-users whose narratives tend to differ from mainstream dominant societal or disciplinary narratives due to differences in lived experiences. In order to empower such communities and ensure designed entities can be meaningful and desirable as well as usable for them, it is important to proactively uncover, interrogate and incorporate a diversity and plurality of end-user narratives into the design process. This study demonstrates how this could be applied in the field of Inclusive Paediatric Mobility (IPM) Design, by setting out to uncover and interrogate the narratives of nine young wheelchair users aged 4-18 years. In-depth narrative interviews are conducted and analysed to unveil five high-level narrative themes including: Independence, Freedom and Choice Beyond Mobility; Social Inclusion and Support Networks; Identity, Customisation and Self-Expression; Accessibility and Adaptations; and Resilience and Determination. An interpretive phenomenological analysis is then conducted to identify archetypal dominant, counter and alternative narratives that exist around each theme. The study elucidates the complexity, duality and dynamicity of end-user narratives and highlights how wheelchairs can act as a vessel for narratives which transcend the primary concept of mobility, encompassing a deeper sense of identity and selfhood, enriched with values, feelings, and opinions related to various areas of life. As well as offering insights into the lived experiences of young wheelchair users, the narratives identified through this study could be adopted in practice by inclusive mobility designers, stakeholders and policymakers to inform sense-making and opportunity framing processes, to ultimately create more meaningful child-centred healthtech solutions and empower young wheelchair users.
生活经验和个人对现实的解释可以通过叙事有效地传达。因此,捕捉和理解叙事在以人为本的设计中是至关重要的,因为它们构成了设计的本质和视角,因此基本上嵌入到设计结果中。由于生活经历的差异,最终用户的叙事往往与主流社会或学科叙事不同,因此当为最终用户设计时,叙事在设计中的作用变得尤为重要。为了增强这些社区的能力,确保设计的实体对他们来说是有意义的、理想的和可用的,主动发现、询问并将最终用户叙述的多样性和多元性纳入设计过程是很重要的。本研究通过揭示和询问9名年龄在4-18岁的年轻轮椅使用者的叙述,展示了如何将其应用于包容性儿科移动(IPM)设计领域。通过深入的叙事访谈和分析,揭示了五个高水平的叙事主题,包括:独立、自由和超越流动性的选择;社会包容和支持网络;身份、定制和自我表达;可及性和适应性;韧性和决心。然后进行解释性现象学分析,以确定围绕每个主题存在的原型主导,反和替代叙事。该研究阐明了最终用户叙事的复杂性、双重性和动态性,并强调了轮椅如何作为叙事的容器,超越了移动性的主要概念,包含了更深层次的身份和自我意识,丰富了与生活各个领域相关的价值观、情感和观点。除了提供对年轻轮椅使用者生活经验的见解外,通过本研究确定的叙述可以被包容性移动设计师、利益相关者和政策制定者在实践中采用,为意义制定和机会框架过程提供信息,最终创造更有意义的以儿童为中心的健康技术解决方案,并赋予年轻轮椅使用者权力。

In-depth narrative interviews are conducted and analysed to unveil five high-level narrative themes including: Independence, Freedom and Choice Beyond Mobility; Social Inclusion and Support Networks; Identity, Customisation and Self-Expression; Accessibility and Adaptations; and Resilience and Determination. An interpretive phenomenological analysis is then conducted to identify archetypal dominant, counter and alternative narratives that exist around each theme. The study elucidates the complexity, duality and dynamicity of end-user narratives and highlights how wheelchairs can act as a vessel for narratives which transcend the primary concept of mobility, encompassing a deeper sense of identity and selfhood, enriched with values, feelings, and opinions related to various areas of life. As well as offering insights into the lived experiences of young wheelchair users, the narratives identified through this study could be adopted in practice by inclusive mobility designers, stakeholders and policymakers to inform sense-making and opportunity framing processes, to ultimately create more meaningful child-centred healthtech solutions and empower young wheelchair users.","PeriodicalId":470195,"journal":{"name":"AHFE international","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135317997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Children's creative growth in rural areas has enormous potential for village development. The main challenges to implementing creativity-inspiring programs for rural children include the children's cognitive development being behind, the lack of teaching resources, and the constrained nature of the curriculum. This study examines the "daily creativity" of rural people from the early stage of design anthropology, using Baishuidong Village, Longhui County, Hunan Province as the backdrop for Hunan University's Design Rural Revitalisation Project. The study discovered a close interaction between humans and material instruments, as well as how "materiality" characterizes the daily inventiveness of rural dwellers. Building models are used by the local community as metaphorical "in-between objects" for the transmission of abstract empirical knowledge while teaching construction skills. This served as our inspiration for creating the "Architects of Huayao" children's inspirational teaching toolkit. Using modular building blocks to impart knowledge of regional architecture, we enhanced the previous teaching toolkit by holding four workshops with 30 third-graders at Baishuidong Primary School. Rural children are given context for their daily lives as well as historical and cultural contexts through the local architecture on the one hand and are encouraged to create through building blocks on the other. This encourages the development of design thinking and innovative thinking in children as well as the creativity of rural children. Rural children's creativity in classroom activities can be efficiently stimulated by the teaching method of using physical models in a cultural setting. Participants in the project, including local kids, teachers, and other volunteers, gave it favorable reviews.
农村儿童的创造性成长对农村发展具有巨大的潜力。实施农村儿童创造力激励计划面临的主要挑战包括儿童认知发展滞后、教学资源缺乏以及课程的有限性。本研究以湖南省隆回县白水洞村为背景,以湖南大学设计乡村振兴项目为背景,从设计人类学的早期阶段考察农村人的“日常创造力”。该研究发现了人类与物质工具之间的密切互动,以及“物质性”如何成为农村居民日常创造力的特征。建筑模型被当地社区用作隐喻性的“中间物体”,在传授建筑技能的同时传递抽象的经验知识。这是我们创作“华耀建筑师”儿童励志教学工具包的灵感来源。在白水洞小学,我们使用模块化的建筑模块来传授区域建筑知识,并在之前的教学工具包的基础上,为30名三年级学生举办了四个工作坊。一方面,通过当地建筑为农村儿童提供日常生活和历史文化背景,另一方面鼓励他们通过积木进行创造。这鼓励了儿童设计思维和创新思维的发展,也鼓励了农村儿童的创造力。在文化背景下运用物理模型的教学方法可以有效地激发农村儿童课堂活动的创造力。该项目的参与者,包括当地的孩子、老师和其他志愿者,都给予了好评。

In a time of digital disruption, users are deciding how they want banks to respond and even exceed their expectations. Banks rushed to face-lift their front-end look and enable non-essential digital services without acknowledging users’ needs. This recent attitude has harmed a good digital banking experience, and consequently the adoption of e-banking. To have a clear vision of how banks can stand out in a digital transformation 634 e-banking users were interviewed from the generations’ X, Y, and Z. A qualitative analysis was conducted using Leximancer software, to determine similarities and differences in three generations’ attitudes toward digital banking. The findings highlighted nineteen concepts grouped into eight key themes, namely: transfers, availability, use, speed, information, price, complex(ity), and market. Digital bank users are concerned about price, speed of transfers, and product information, valuing the easy availability of services and operations in the financial market, with some constraints about the complexity of options used to manage their accounts and savings. While Gen X (older age) looks at digital banking mainly for the availability of services, Gen Y (middle age) takes more advantage of digital banking to explore the bank/financial market and perform operations anywhere, and Gen Z (younger age) simply for transfers. This study contributes to understanding the adoption of digital banking, allowing to propose a new conceptual map to explain e-banking usage and identifying what is more important for each Gen X, Y, and Z generation may adopt digital banking.
在数字化颠覆的时代,用户正在决定他们希望银行如何应对,甚至超越他们的期望。银行急于改善其前端外观,启用非必要的数字服务,而没有认识到用户的需求。最近的这种态度损害了良好的数字银行体验,从而影响了电子银行的采用。为了清楚地了解银行如何在数字化转型中脱颖而出,我们采访了634名来自X、Y和z世代的电子银行用户。我们使用Leximancer软件进行了定性分析,以确定三代人对数字银行态度的异同。调查结果强调了19个概念,分为8个关键主题,即:转移、可用性、使用、速度、信息、价格、复杂性(城市)和市场。数字银行用户关心的是价格、转账速度和产品信息,重视金融市场上服务和操作的易得性,同时对用于管理账户和储蓄的选项的复杂性有一些限制。X世代(年龄较大的人)主要将数字银行视为服务的可用性,Y世代(中年)更多地利用数字银行探索银行/金融市场并在任何地方开展业务,Z世代(年龄较小的人)只是为了转账。本研究有助于理解数字银行的采用,允许提出一个新的概念图来解释电子银行的使用,并确定X、Y和Z世代可能采用数字银行的更重要的因素。

There are billions of operations happening in a wide range of sectors on a daily basis. When it comes to the hospitality sector, it appears essential to handle POS operations in a more efficient way in restaurants. To fill the gap in the studies about event log data in the fast food restaurant POS context, an approach needs to be developed. Regarding these, in this study, restaurant event log data for taking orders are comprehensively analyzed using process mining principles and machine learning applications to increase productivity. After the discovery of processes, the bottlenecks of the existing system were extracted in fast food restaurant point of sale (POS). The main focus was determined as order-taking process times, which can be the most troubled part of the fast food delivery process. Regression analysis was conducted to identify possible reasons for increasing time for order taking in a restaurant pos. This analysis can extract the main drawbacks of the system and provide insights to solve problematic points in order to increase productivity. Process discovery techniques, such as heuristics miner, directly follows graph (DFG) are used under process mining methodologies to discover event logs in a visual manner in the background. To be able to understand the logic of event logs deeply, exploratory data analysis techniques were performed to identify the effect of log activity types by also focusing on their respective attributes. Afterwards, it needed to adopt performance analysis, comparative, and action-oriented process mining techniques to evaluate, identify, and operationally support the business. In addition to process mining approaches, feature engineering, descriptive statistics techniques and outlier elimination are used along with various regression methods such as XgBoost, Random Forest to identify the relationship between variables of the system. The detailed descriptions of the feature relations are also explained to understand how variables affect the order taking time directly or indirectly. After that, the study found possible reasons, such as how many products are sold or how many different operators are working on that POS, affecting ordering time and how much they are specific to its context. By identifying these reasons, it is shown that order-taking processing times in a restaurant POS can be dramatically decreased with specific recommended actions in particular contexts. By applying research findings, order-taking process times are expected to improve by around 21% in a territorial business, which implies productivity growth in POS environments. Consequently, the study first showed how different techniques can be used to identify outliers in relationship metrics in restaurant POS event log data. Secondly, it is a direct, crucial example of what factors affect a restaurant's POS processes and how much. Meanwhile, it significantly suggests machine learning integrated process mining approaches by combining the mentioned
每天在各行各业都有数十亿的业务在进行。在酒店业,以更有效的方式处理餐厅的POS操作似乎至关重要。为了填补快餐店POS环境下事件日志数据研究的空白,需要开发一种方法。关于这些,在本研究中,使用流程挖掘原理和机器学习应用程序全面分析了餐厅接受订单的事件日志数据,以提高生产力。在发现流程后,提取现有系统在快餐店销售点中的瓶颈。主要的焦点被确定为接受订单的过程时间,这可能是快餐配送过程中最麻烦的部分。进行了回归分析,以确定增加餐厅点单时间的可能原因。这种分析可以提取系统的主要缺点,并提供解决问题点的见解,以提高生产力。在流程挖掘方法下,使用启发式挖掘器、直接跟随图(DFG)等流程发现技术在后台以可视化的方式发现事件日志。为了能够深入理解事件日志的逻辑,执行了探索性数据分析技术,通过关注日志活动类型各自的属性来识别其影响。之后,它需要采用性能分析、比较和面向操作的流程挖掘技术来评估、识别和操作性地支持业务。除了过程挖掘方法外,还使用特征工程、描述性统计技术和离群值消除以及各种回归方法(如XgBoost、Random Forest)来识别系统变量之间的关系。对特征关系的详细描述也进行了解释,以了解变量是如何直接或间接地影响花费时间的顺序。在那之后,研究发现了可能的原因,比如销售了多少产品,或者有多少不同的操作员在POS上工作,影响订购时间,以及它们在多大程度上是特定于上下文的。通过识别这些原因,我们可以看到,在特定的上下文中,使用特定的推荐操作可以显著减少餐厅POS中的订单处理时间。通过应用研究结果,在区域业务中,订单处理时间预计将提高约21%,这意味着POS环境中的生产率提高。因此,该研究首先展示了如何使用不同的技术来识别餐馆POS事件日志数据中关系指标的异常值。其次,这是一个直接的、关键的例子,说明了哪些因素影响了一家餐厅的POS流程,影响程度有多大。同时,通过结合上述技术,它显著地提出了机器学习集成过程挖掘方法。最后,本文揭示了这种工艺结构对操作者的使用效率,这是一个有待进一步研究的问题。
