Background: The disease burden of ischemic heart disease (IHD) continues to increase. This study aimed to assess the age, period, and cohort effects on the long-term trends of IHD incidence and mortality in China from 1990 to 2019.

Methods and results: The data were obtained from the Global Burden of Disease Study (GBD) 2019, and the age-standardized incidence/mortality rate (ASIR/ASMR) was calculated. The age-period-cohort (APC) model, which is a generalized linear model revealing the correlation of disease rate and attained age, period, and cohort, was applied to estimate the net drift (estimated annual percentage change [EAPC]s), the local drifts (age-specific EAPCs), the age, period, and cohort effects. The analyses elucidated that the ASIR and ASMR of IHD declined after 2013. The net drift of incidence was 0.212% in females, and the net drift of mortality was 0.371% in males. The local drifts of mortality were above 0 in males aged 20-84 years and in females aged 65-84 years. The age effects showed elevated trends during the study period. The period effects declined after 2013. The cohort effects of mortality in males were higher than that in females.

Conclusions: The decrease of ASIR and ASMR indicated that measures to prevent IHD have been effective in China. However, the cardiovascular health of the elderly and males should be considered in future policy decisions.

背景:缺血性心脏病(IHD)的疾病负担持续增加。本研究旨在评估1990-2019年中国缺血性心脏病发病率和死亡率长期趋势的年龄、时期和队列效应:数据来自《2019 年全球疾病负担研究》(GBD),并计算了年龄标准化发病率/死亡率(ASIR/ASMR)。应用年龄-时期-队列(APC)模型估算净漂移(估计年百分比变化[EAPC]s)、局部漂移(特定年龄的EAPCs)、年龄、时期和队列效应,该模型是一种广义线性模型,揭示了疾病发病率与年龄、时期和队列的相关性。分析表明,2013 年后,非霍乱急性期发病率和非霍乱急性期死亡率均有所下降。女性发病率的净漂移率为0.212%,男性死亡率的净漂移率为0.371%。在 20-84 岁的男性和 65-84 岁的女性中,死亡率的局部漂移超过了 0。在研究期间,年龄效应呈上升趋势。时期效应在 2013 年后有所下降。男性死亡率的队列效应高于女性:ASIR和ASMR的下降表明,中国预防心肌梗死的措施是有效的。结论:ASIR和ASMR的下降表明,中国预防心血管疾病的措施已见成效,但在未来的政策决策中应考虑老年人和男性的心血管健康。

One of the eight wastes that Lean production, inspired by the Toyota Production System, proposes to study is the underutilization of workers, that is, the inadequate use of their intelligence. The sense is to provide listening and participation in improvement projects, of professionals who have experience in daily life and, in many cases, consistent academic qualifications.  The objective of this work is to study the importance of the participation of teachers and employees of a basic education school in the construction of new routines and work methods, in the context of the Lean management philosophy, justified by the scarcity of scientific literature on the subject. Brazil has about 184,000 basic education schools with one million four hundred thousand teachers working from kindergarten to the ninth grade of elementary school, and of these, 83.2% have a college degree, a percentage that grows every year. About the schools, 21.7% are private, 61.3% municipal, 16.6% state, and 0.4% are federal schools. As a research methodology, a systematic review of the literature was adopted, based on the PRISMA protocol, allowing the identification of 53 records, 14 of which were included in the literature review, due to their adherence to the researched subject. The main contribution of this paper is the identification of a research gap involving the underutilization of workers and adoption of the Lean management philosophy in the education sector, as well as a conceptual proposal of the positive impact on the educational organization results by not underutilizing workers, without wasting their intelligence.
受丰田生产系统的启发,精益生产提出要研究的八个废物之一是工人的利用不足,即他们的智力利用不足。这种意义是让具有日常生活经验的专业人士,在许多情况下,具有一致的学历,倾听并参与改进项目。这项工作的目的是在精益管理哲学的背景下,研究基础教育学校的教师和员工参与构建新的日常工作和工作方法的重要性,因为缺乏有关该主题的科学文献。巴西约有18.4万所基础教育学校,从幼儿园到小学九年级有140万名教师,其中83.2%拥有大学学位,这一比例每年都在增长。关于学校,21.7%是私立学校,61.3%是市级学校,16.6%是州立学校,0.4%是联邦学校。作为一种研究方法,根据PRISMA方案,对文献进行了系统综述,从而确定了53项记录,其中14项记录因其与研究对象的一致性而被纳入文献综述。本文的主要贡献是确定了一个涉及员工利用不足的研究缺口,并在教育部门采用了精益管理哲学,以及在不浪费员工智力的情况下,不充分利用员工对教育组织结果产生积极影响的概念性建议。

The growing importance of agriculture in the Brazilian economy makes it essential that agricultural companies seek to increase their logistics competitiveness. This study aimed to compare and analyze the impact of seasonality of grain harvest and specific events, such as the 2018 Brazil truck drivers’ strike, on the prices of inbound and outbound freight in a multinational company located in several Brazilian states. It focused on the CIF (Cost, Insurance, and Freight) routes of the company between 2015 and 2019 in Brazil, and the relationship between time of year and cost of transportation. These data were analyzed in a descriptive level after being treated by statistical analysis. This study showed that the costs of outbound freight suffered greater increases compared to the inbound freight due to the seasonality of grain harvest and the 2018 Brazil truck drivers’ strike.
农业在巴西经济中日益重要,这使得农业公司必须寻求提高其物流竞争力。本研究旨在比较和分析粮食收获的季节性和特定事件(如2018年巴西卡车司机罢工)对一家位于巴西多个州的跨国公司进出港货运价格的影响。它重点关注了该公司2015年至2019年在巴西的CIF(成本、保险和运费)路线,以及一年中的时间与运输成本之间的关系。这些数据经过统计分析后,在描述性水平上进行了分析。这项研究表明,由于粮食收获的季节性和2018年巴西卡车司机罢工,与入境运费相比,出境运费的上涨幅度更大。

The concept of Industry 4.0 is very recent and has not been fully consolidated, and, for this reason, comprehensive implementations by the industrial sector may not be prudent. Studies show that only fundamentals of Industry 4.0 do not guarantee characteristics such as quality, for example, in production processes. Thus, lean production concepts are probably being used together to cover deficiencies in Industry 4.0. In this work, a literature review is proposed that points out where lean production tools are being used in the production processes of Industry 4.0. Using the results of this search, an analysis of the most important lean production tools, which appear in the works, has been made. The analysis has shown what is being used, in terms of the lean tools, in the production processes of Industry 4.0, and what improvements are provided from these tools.
工业4.0的概念是最近才出现的,尚未得到充分巩固,因此,由工业部门全面实施可能并不谨慎。研究表明,只有工业4.0的基础并不能保证生产过程中的质量等特征。因此,精益生产的概念可能会被用来弥补工业4.0的不足。在这项工作中,提出了一项文献综述,指出精益生产工具在工业4.0的生产过程中使用的地方。利用这一搜索的结果,分析了最重要的精益生产工具,出现在工作中,已作出。分析显示了在工业4.0的生产过程中使用了哪些精益工具,以及这些工具提供了哪些改进。

Flexible manufacturing processes improve profitability and competitiveness for the company through an efficient process, with quality in a short time, and contribute to achieving low costs. One of the approaches that have been currently developed to improve the flexible manufacturing process is simulation. Simulation models consist of an assertive and powerful tool in strategic planning.  It permits a controlled way of the company's reality so that it was possible to study and analyze the organization's current situation under several circumstances without altering the production's physical environment and involving low costs. Accordingly, this study's primary purpose was to develop a simulation model to verify bottlenecks' existence in the bearing manufacturing process. For this, a case study is presented, and it was used modeling/simulation with Arena Software as a research method. The results showed no bottlenecks in the manufacturing process.

The blockchain was initially developed for use in the banking sector. However, over time, different areas of knowledge have adopted these technologies, including transportation operations. This use of blockchain in the transport sector is mainly due to the ability of this technology to enable the data generated by these activities to be reliable. In addition to aspects related to data immutability, blockchain enables greater data privacy, as well as making it possible for the data control process to be decentralized. In this sense, it was carried out a systematic literature review (RSL) to identify the general publications panorama on the topic, and to identify the capabilities enabled by the blockchain in the context of transportation operations. RSL has great potential to make it possible to deepen the literature on a given topic. The analysis of the RSL results included the realization of two stages. The first step consisted of a quantitative analysis of data from a sample of 50 articles, to identify this research field about the distribution by journal, year, and author. This first step enabled a general analysis of the field of study on the use of blockchain in transportation. The second stage consisted of a qualitative analysis of the ten most relevant articles in this field of study. In this way, it was possible to understand more about the use of blockchain in transport operations, as well as to identify seven capabilities enabled by the blockchain. These capabilities represent abilities that blockchain technology allows the transport sector today, demonstrating the importance of its use, as well as of study.
区块链最初是为在银行业使用而开发的。然而,随着时间的推移,不同的知识领域已经采用了这些技术,包括运输业务。区块链在运输部门的使用主要是由于这项技术能够使这些活动产生的数据可靠。除了与数据不变性相关的方面外,区块链还实现了更大的数据隐私,并使数据控制过程可以去中心化。从这个意义上说,它进行了一次系统的文献综述(RSL),以确定有关该主题的一般出版物全景,并确定区块链在运输运营背景下的能力。RSL在深化特定主题的文献方面具有巨大的潜力。对RSL结果的分析包括两个阶段的实现。第一步是对50篇文章的样本数据进行定量分析,以确定该研究领域的期刊、年份和作者分布情况。这第一步使人们能够对区块链在交通运输中的应用进行全面分析。第二阶段是对这一研究领域中最相关的十篇文章进行定性分析。通过这种方式,可以更多地了解区块链在运输运营中的使用,并确定区块链所支持的七种功能。这些能力代表了区块链技术为当今交通部门提供的能力,表明了其使用和研究的重要性。

The positional modeling of the 2T6R robot mechanism is done for inverse kinematics, i.e. when the imposed positions of the end effector T, imposed, belonging to the final element 3, are known and the necessary positions and speeds of the two input motors, the two leading elements, are determined, 1 and 6. It is proposed to solve a simple algorithm in the program MathCad 2000, which uses for initiation the logical function If Log. The kinematic output parameters, i.e. the parameters of the foot and practically of the final effector, i.e. those of the point marked with T, will be determined for initiating the working algorithm using the logical functions, "If log (ical)", with the observation that here plays the role of parameters input; is positioned as already specified in reverse kinematics when the output is considered as input and input as output. The logical functions used, as well as the entire calculation program used, were written in Math Cad 2000.
2T6R机器人机构的位置建模是针对逆运动学进行的,即当末端执行器T所施加的位置为已知时,即当末端执行器T所施加的位置为最终单元3时,两个输入电机的两个先导单元1和6的必要位置和速度确定时。提出了解决MathCad 2000程序中一个简单的算法,该算法使用逻辑函数If Log初始化。将使用逻辑函数“If log (logical)”确定运动输出参数,即最终执行器的足部和实际的参数,即标记为T的点的参数,以启动工作算法,并观察这里起参数输入的作用;在逆向运动学中,当输出被认为是输入,输入被认为是输出时,定位为已经指定的位置。所使用的逻辑函数以及所用的整个计算程序都是在Math Cad 2000中编写的。

Internationalization is defined as an integration process of international, intercultural or global dimensions with educational purpose and offers. There are many dimensions of educational institutions internationalization from research partnership to international mobility. Among the several requirements for students to participate in exchanging programs promoted by international universities and organizations is English language proficiency. On the other hand the proficiency level requirements can vary according to the mobility programs which set the minimum English level. One example is the SAKURA Science High School Program promoted by the Japan Science and Technology Agency (JST) which selected science and technology students to participate in an exchanging program in Japan. In order to be selected, applicants needed to have B1 (CEFRR) as minimum English proficiency level. Thus this study aims to investigate if Brazilian students of an educational institution have such required level to successfully take part in mobility programs. The qualitative methodology of this research includes documents analysis - internationalization documents and English course program - and questionnaires to students and English teacher. The results show that students are expected to achieve B1 level by the end of high school according to the English subject program. However students believe that they do not have such level in speaking skill which would be one of the main skill in JST program. Most of them classify their level in A2. Furthermore the English teacher claims that although some students have already achieved B1 or even higher level the majority is at A2.Thus in order to allow more students to participate in mobility programs the institution should invest in extra-curricular English courses to increase study hours and focus more on developing speaking skills.
国际化被定义为具有教育目的和服务的国际、跨文化或全球维度的整合过程。教育机构国际化有很多方面,从研究合作到国际流动。学生参加国际大学和组织推动的交换项目的几项要求之一是英语语言能力。另一方面,熟练程度的要求可能会根据流动项目的最低英语水平而有所不同。日本科学技术振兴机构(JST)推动的“樱花科学高中计划”就是一个例子,该计划选择科学和技术学生参加日本的交流计划。为了被选中,申请人需要达到B1 (CEFRR)作为最低英语水平。因此,本研究的目的是调查如果一个教育机构的巴西学生有这样的要求水平,成功地参加流动计划。本研究的定性研究方法包括文献分析-国际化文献和英语课程计划-以及对学生和英语教师的问卷调查。结果显示,根据英语课程计划,学生们有望在高中结束时达到B1水平。然而,学生们认为他们在口语技能上没有达到这样的水平,而口语技能是JST项目的主要技能之一。他们中的大多数人把自己的水平归为A2。此外,英语老师声称,虽然一些学生已经达到了B1甚至更高的水平,但大多数是在A2。因此,为了让更多的学生参加流动项目,机构应该投资于课外英语课程,以增加学习时间,更多地关注发展口语技能。
