Biofidel femur Models with finite elements were developed using a specific segmentation combination with computed tomography and solid modeling tools capable of representing bone physiology and structural behavior. These biofidel Finite Element Models (FEM) are used to evaluate the change in the physiological distribution of stress in the prosthesis femur and to evaluate the new design criteria for biopsy biopsy biopsy biopsy. The proposed belief patterns allowed us to adequately take into account the non-isotropic features of the proximal femoral epiphysis and isotropic behavior in diaphysis to explain the critical changes in stress distribution in a femur resected after the implantation of a traditional articular prosthesis. It has been shown that a wide range of femoral diaphyses is completely protected by rigid prostheses that significantly alter the physiological distribution of stress, which should guarantee healthy growth and bone regeneration.
利用特定的分割结合计算机断层扫描和能够代表骨骼生理和结构行为的实体建模工具,开发了具有有限元的生物股骨模型。这些生物有限元模型(FEM)用于评估假体股骨内应力生理分布的变化,并评估活检活检的新设计标准。所提出的信念模式使我们能够充分考虑股骨近端骨骺的非各向同性特征和骨干的各向同性行为,以解释传统关节假体植入后股骨切除后应力分布的关键变化。研究表明,大范围的股骨干完全受到刚性假体的保护,这显著地改变了应力的生理分布,这应该保证健康的生长和骨再生。

Healthcare logistics play an important role in management, being attributed the activities of acquisition, distribution and movement of materials, professionals and patients. This work aims to develop a study, using the healthcare logistics in the movement of patients in the third health region of Paraná, proposing a linear programming problem that will pass through a computational simulation, considering the existing demands and constraints in the system, aiming to optimize the flow of patients from this region. The present study developed four mathematical models, based on demands and constraints followed by linear programming in order to find the best possible solution for the flow of patients from the third health region of the state of Paraná. The study developed reached its goal of optimization, generating an economy in the transportation of patients. Through the analysis of the results, it is concluded that the model that best suits the presented problem is the one of costs minimization, since the one of vehicles presented higher costs. Possibly the model that minimizes the vehicles would bring better results if the vehicles were not outsourced, but of the Ponta Grossa City Hall (PMPG). Was possible to verify the importance of the theme, especially when referring to the flow of patients in the health services due to the lack of studies with this specific approach. Even with the scarcity of data, it is possible to notice the potential for improvements on this patient transport system.
医疗保健物流在管理中发挥着重要作用,可归因于材料、专业人员和患者的获取、分发和移动活动。本工作旨在开展一项研究,利用paranar第三健康区域的医疗物流,提出一个线性规划问题,将通过计算模拟,考虑到系统中现有的需求和约束,旨在优化该区域的患者流量。本研究建立了四个数学模型,以需求和约束为基础,遵循线性规划,以找到来自帕拉纳州第三卫生区域的患者流量的最佳解决方案。这项研究达到了优化的目标,节省了病人的运输费用。通过对结果的分析,得出最适合该问题的模型是成本最小化模型,因为车辆的成本较高。如果车辆不外包,而是外包给蓬塔格罗萨市政厅(PMPG),那么最小化车辆的模式可能会带来更好的结果。由于缺乏对这一具体方法的研究,因此有可能核实这一主题的重要性,特别是在提到保健服务中的病人流动时。即使在数据匮乏的情况下,也有可能注意到改进这一病人运输系统的潜力。

World potato production in 2017 was over 388.2 million tons, being the fourth largest in volume in the world, where the highest world producers are China, India, Russia, Ukraine, and the United States. Brazil occupies the 21st position in the ranking of the largest potato producers in the world, with a production volume of 3.6 million tons, with the main producers being the states of Minas Gerais, Paraná, and São Paulo, which together produce the equivalent of 75 % of the Brazilian total. Knowledge about the positioning of the consumer is important for stakeholders in the potato production chain, aiming at the identification of personal factors that influence potato consumption, as well as the recognition of opportunities, seeking to meet the wishes and needs of consumers. Also, it is relevant to check consumer sensitivity to fluctuations in retail prices. Few studies show which personal aspects influence consumers' decision to purchase potatoes, as well as they react to changes in price. Thus, this study sought to identify which personal aspects influence the purchase of potatoes and how the consumer positions himself concerning changes in prices, through the analysis of primary data answered by 170 people in 38 cities of the state of São Paulo. The collected information was processed using electronic spreadsheets in Microsoft Excel software and the analyzes developing using Multiple Linear Regression with Heteroscedasticity (MLR), with the aid of the Stata 15 software. Families with children, with more than two adults in the composition, and age are the personal aspects that influence the acquisition of potatoes. As the potato is a popular product, with easy access and relatively low prices, the levels of education and income do not interfere with consumption, since at times when prices are small the quantity consumed remains unchanged.
2017年,世界马铃薯产量超过3.882亿吨,是世界第四大马铃薯产量国,其中世界产量最高的是中国、印度、俄罗斯、乌克兰和美国。巴西在世界最大土豆生产国排行榜上排名第21位,产量为360万吨,主要生产国是米纳斯吉拉斯州、巴拉那州和圣保罗州,这些州的总产量相当于巴西总产量的75%。关于消费者定位的知识对马铃薯生产链中的利益相关者来说很重要,目的是识别影响马铃薯消费的个人因素,以及识别机会,寻求满足消费者的愿望和需求。此外,检查消费者对零售价格波动的敏感性也是相关的。很少有研究表明,哪些个人因素会影响消费者购买土豆的决定,以及他们对价格变化的反应。因此,本研究试图通过分析圣保罗州38个城市170人回答的主要数据,确定哪些个人因素影响土豆的购买,以及消费者如何看待价格变化。使用Microsoft Excel软件中的电子表格处理收集的信息,并在Stata 15软件的帮助下使用异方差多元线性回归(MLR)进行分析。有孩子、有两个以上成年人的家庭以及年龄是影响土豆获得的个人因素。由于土豆是一种受欢迎的产品,易于获得,价格相对较低,教育水平和收入水平不会干扰消费,因为在价格较低的时候,消费量保持不变。

Nowadays, one of the factors that enable businesses to adapt to markets that are constantly renewed and changing due to the ever-increasing flow of information, and perhaps the most important, is innovation. Innovation is a topic that is frequently studied by both markets and academics. However, the increase in the quantity of studies conducted is far from meeting the need in this field. As a result of the shortening of product life cycles in current market conditions, companies are obliged to continuously innovate in order to sustain their existence. Increasing raw material and resource diversification requirement due to the increasing need for innovation made it necessary to examine and understand the supply chain in the context of innovation. The importance of innovation, especially in the case of participation by suppliers in innovation for a competitive advantage, has resulted in many in-depth studies published in research papers in the field. In this study, articles published in the Web of Science database between 1996-2020 and covering the topics of  supply chain and innovation were analyzed in order to reveal the patterns of supply chain management and innovation research, identify relative deficiencies and provide some guidelines. For this purpose, a systematic literature review and bibliometric analysis related has been made. It has been possible to determine the effective actors in the field by including the distribution of the concepts in question according to time, countries, universities and journals. In addition, as a result of the keyword analysis, the evolution and open points of the field over time are among the findings of the study.
如今,由于信息流不断增加,企业能够适应不断更新和变化的市场,其中一个因素也许是最重要的,那就是创新。创新是市场和学术界经常研究的一个话题。然而,研究数量的增加远远不能满足这一领域的需要。在当前的市场条件下,由于产品生命周期的缩短,公司必须不断创新以维持其生存。由于对创新的需求不断增加,原材料和资源多样化的要求不断增加,因此有必要在创新的背景下检查和理解供应链。创新的重要性,特别是在供应商参与创新以获得竞争优势的情况下,已经导致该领域的许多深入研究发表在研究论文中。本研究通过对Web of Science数据库1996-2020年间发表的供应链与创新相关论文进行分析,揭示供应链管理与创新研究的模式,找出相关不足,为供应链管理与创新研究提供指导。为此,本文进行了系统的文献综述和文献计量学分析。通过将有关概念按时间、国家、大学和期刊的分布情况包括在内,可以确定该领域的有效行动者。此外,作为关键字分析的结果,该领域随时间的演变和开放点是研究的结果之一。

The modelling of systems using systemic tools has been for a few years, a subject which has attracted the attention of scientists and especially researchers to allow designers to acquire a rigorous approach to problem solving using the capabilities of already existing methods and tools. This document presents a contribution in the field of modelling, where a methodology based on two methods has been proposed. The first concerns the functional analysis to extract the use functions and the constraint parameters from the system. In this methodology, the static functional study is carried out using the SADT method. On the other hand, the dynamic behavioral analysis is carried out by the SA-RT method. Then, we used a behavioral and parametric analysis, the Bond Graph method, to observe the evolution of representative quantities of a photovoltaic system.
使用系统工具对系统进行建模已经有几年的历史了,这一主题吸引了科学家,尤其是研究人员的注意,使设计师能够利用现有方法和工具的能力获得严格的解决问题的方法。本文件在建模领域做出了贡献,提出了一种基于两种方法的方法。第一个是从系统中提取使用函数和约束参数的函数分析。在该方法中,使用SADT方法进行静态功能研究。另一方面,采用SA-RT方法进行动态行为分析。然后,我们使用行为和参数分析,即键合图方法,来观察光伏系统代表量的演变。

Then, we used a behavioral and parametric analysis, the Bond Graph method, to observe the evolution of representative quantities of a photovoltaic system.","PeriodicalId":54124,"journal":{"name":"Independent Journal of Management & Production","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43597116","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}

The advent of COVID-19 has escalated into a pandemic and, as a result of infected cases and human fatalities, it tends to rise day by day across the globe. This also ignited concerns of a looming fiscal slump and recession on the different economic sectors as well. The effect of this pandemic is much more significant in developing countries like India due to the already declining growth rate, inadequate health services, and a growing population residing in severe poverty.  This paper attempts to understand the impact of COVID‐19 pandemic on the Indian economic sectors by employing a hierarchical approach, based on multi-criteria analysis to understand the impact on primary, secondary, tertiary and quaternary sectors by concerning the political, economic, socio‐cultural and technology consequences of COVID‐19. A process-based multi-criteria hierarchical approach has been used to determine the effect of the same and has been prioritized in the sequential sequence.
新冠肺炎的出现已升级为一场大流行,由于感染病例和人类死亡,它在全球范围内呈日益上升的趋势。这也引发了人们对不同经济部门即将出现的财政衰退和衰退的担忧。由于增长率已经下降、卫生服务不足以及生活在严重贫困中的人口不断增加,这场疫情对印度等发展中国家的影响要大得多。本文试图通过采用分层方法,基于多标准分析,通过关注新冠肺炎的政治、经济、社会文化和技术后果,了解新冠肺炎疫情对印度经济部门的影响。基于过程的多标准分层方法已被用于确定相同的效果,并已按顺序排列优先级。

The study investigated the effect of monetary policy on economic growth during post structural adjustment programmer in Nigeria. It used the expo-facto design. Secondary data for the period of 1985-2015 were utilized. The data were extracted from the Central Bank of Nigeria (CBN) Statistical Bulletin and the National Bureau of Statistics (NBS). The linear regression with the application of Ordinary least Squares (OLS) technique was employed to estimate the parameters of the model numerically. Finding revealed that broad money supply had a positive and significant effect on economic growth in Nigeria during post structural adjustment programmer from 1986-2015. Interest rate had a negative and significant effect on economic growth in Nigeria during the same period and inflation rate had a positive and insignificant effect on economic growth in Nigeria at the same time. The study recommended that Central Bank of Nigeria should facilitate the emergence of market based interest rate that would attract both domestic and foreign investments, as well as create jobs, and promote non-oil export, while reviving industries that are currently operational, far below installed capacity. In order to strengthen the financial sector, the Central Bank has to encourage the introduction of more financial instruments that are flexible enough to meet the risk preferences and sophistication of operators in the financial sector.
本研究考察了尼日利亚结构调整后货币政策对经济增长的影响。它采用了世博会的设计。利用了1985-2015年期间的二手数据。数据来自尼日利亚中央银行(CBN)统计公报和国家统计局(NBS)。采用线性回归和普通最小二乘(OLS)技术对模型参数进行了数值估计。研究发现,1986-2015年结构调整后,广义货币供应量对尼日利亚经济增长有显著的正向影响。同期利率对尼日利亚经济增长的影响为负且显著,同时通货膨胀率对尼日利亚经济增长的影响为正且不显著。该研究建议,尼日利亚中央银行应促进以市场为基础的利率的出现,以吸引国内外投资,创造就业机会,促进非石油出口,同时振兴目前正在运营的工业,远远低于装机容量。为了加强金融部门,中央银行必须鼓励引入更多灵活的金融工具,以满足金融部门经营者的风险偏好和复杂性。
