To explore the effect of the Plan-Do-Check-Action (PDCA) cycle on hand hygiene and nosocomial infection quality of orthopedic medical staff.

This paper aims to present improvement actions to reduce the failure risk of a new vehicle cabin air transporter developed in an automotive plant in the Sul Fluminense region by applying the Failure Modes and Effect Analysis (FMEA) tool. This analysis method enables the equipment to reduce some existing problems. Thus, it was possible to increase the demand for vehicles, expected by the end of the year 2018. For this purpose, a team was formed with employees from the main areas involved who raised the main failure modes of the equipment through the brainstorming technique. The FMEA worksheet was filled using the severity, occurrence, and detection classification tables to calculate the Risk Priority Number (RPR). Then, it was suggested to apply the technique with the necessary improvement actions for the failure modes, broken down in a 5W1H worksheet. In a conclusion, the importance of applying the FMEA before acquiring new equipment was demonstrated, avoiding waste, and guaranteeing the company's efficiency.

The semiconductor industry faces the dual challenge of risk assessment and process improvement. This paper introduces a framework that integrates Failure Mode and Effects Analysis (FMEA) and Plan-Do-Check-Act (PDCA) cycle to address these challenges effectively. FMEA serves as the initial step to identify potential risks within the system, followed by applying the PDCA cycle to systematically address and enhance the identified risks. The comparison between the initial Risk Priority Number (RPN) value, determined through FMEA, and the post-RPN in PDCA value gauges the success of the framework. Implementing the system in a semiconductor assembly line yielded a significant 51% improvement in RPN, with additional Lean tools incorporated into PDCA, such as SMART goals, 6M, and multi-voting. This integrated framework amplifies risk management, fosters continuous improvement, optimizes resource utilization, and empowers data-driven decisions, ultimately bolstering organizational growth. However, the study acknowledges limitations such as its single-case focus and potential RPN calculation subjectivity.

Traffic enforcement is one of the 3E's of traffic safety measures. Traffic enforcement has been reported to reduce traffic accidents worldwide; however, significant regional differences exist in its effectiveness. This study summarizes the history of the effects of traffic enforcement on reducing traffic accidents in Japan. In particular, scientific approaches and more efficient enforcement since 2000 have been described in the research results. Although the implementation of data-based PDCA (Plan-Do-Check-Action) has steadily reduced the number of traffic fatalities, further reductions are expected through the use of new technologies such as artificial intelligence.

Pyrrole‐2,5‐dicarboxylic acid (PDCA) is a heterocyclic aromatic dicarboxylic acid that may emerge as a new monomer for polyester production. Compared to its structurally related and bio‐based furan‐2,5‐dicarboxylic acid (FDCA) that is already used for the production of polyethylene furanoate (PEF), PDCA shows excellent potential as its nitrogen can be targeted for further derivatization, thus enabling tuning of the properties of a PDCA containing polymer. In light of this, we recognized the need to explore efficient synthetic approaches for producing PDCAs in high yields. Here, we report a five‐step synthesis route for N‐substituted PDCAs starting from pyrrole, with total yields up to 42 %. The synthetic approach allowed the introduction of several different functional moieties to the pyrrole nitrogen, such as aliphatic saturated and unsaturated side‐chains, as well as benzylic groups.

The purpose of this study is to determine how the Bangladeshi garment industry's sewing defect reduction and productivity enhancement are affected by the Plan, Do, Check, Act (PDCA) and 5S (Sort, Set in order, Shine, Standardize, Sustain) techniques. One of the main reasons for production delays and increased costs is sewing defects. By reducing defects, improving Overall Equipment Effectiveness (OEE), and methodically using integrated PDCA concepts, the study aims to streamline and expand the production flowline while increasing throughput. To continuously evaluate and improve the sewing process, the 5S method is also employed. Tools like cause-effect diagrams and Pareto charts were used to identify the defect correctly. The OEE was used to evaluate the actual efficiency. The integration of 5S and PDCA as a lean methodology was utilized to minimize the defect rate and maximize quality to improve efficiency. For this purpose, data was collected from some renowned factories in Bangladesh. This mixed-integrated methodology is used in the study to integrate quantitative defect analysis with worker satisfaction along with efficiency surveys. The findings should offer valuable insights to the RMG industry in Bangladesh, as producers seek sustainable methods to increase productivity and enhance product quality while mitigating the impact of sewing errors on their production procedures. OEE was increased by almost 3-4% through this research. [ABSTRACT FROM AUTHOR]

Purpose: This paper explores the influence of ISO 9001:2015 certification on business performance in the packaging industry in South Africa. Additionally, the study proposes a comprehensive and sustainable quality management system (QMS) framework that harmonises with the stipulated requirements of the standard to address the challenges posed by the unpredictable and volatile business landscape. Design/methodology/approach: This study adopted a quantitative research method and collected empirical data through surveys conducted in various mainstream packaging material sectors across South Africa. The participants were selected using a stratified sampling technique. The collected data underwent descriptive and inferential analysis. Findings/results: The findings confirmed that the implementation of the ISO 9001:2015 certification has a significant influence on organisational performance. However, organisations should focus on integrating all business processes, prioritising lean manufacturing and ensuring effective leadership engagement at the strategic, tactical and operational levels to maximise the potential benefits of ISO 9001:2015. Practical implications: The proposed integrated framework facilitates the detection and analysis of ineffective activities across organisational structures and processes within the supply chain. This comprehensive approach measures and improves all risk parameters, enabling sustainable development and providing insights into the impact and contributions of input variables to business operations. Originality/value: This study addresses a practical gap in the industry by examining how ISO 9001:2015 certification can be effectively applied to enhance business improvement, even in the absence of the standard being overdue for revision. It provides valuable insights into strategies for leveraging the certification’s potential to optimise business performance in such dynamic environments.

Abstract Improving a technical work environment encourages creativity and enhances research efforts. The conception of a modular ventilation laboratory aims at free construction and assembly of the air circuit in different shapes, sizes, and operational variations. The modules allow the development of academic experiences, automatic data acquisition from sensors, data analysis, and verification of concepts related to ventilation in underground mines. The modular ventilation laboratory uses a teaching methodology based on a playful and low-cost way to teach engineering, mainly underground mine ventilation. The aim of this work is essentially to propose the creation of a modular underground mine ventilation laboratory to facilitate engineering teaching and allow the simulation of real situations. The Plan-Do-Check-Act (PDCA) methodology was used to develop a framework for building the modular educational ventilation laboratory. This methodology encompasses project planning and studying, applying the Ventsim® software, and the design of a teaching laboratory with sensors and microcontrollers using the Internet of Things (IoT). The results involve the construction of a physical project with PVC (polyvinyl chloride) pipes and connections and electronic circuits. The project presents the main parameters monitored in underground mines and foresees the simulation of scenarios, aiming to facilitate an understanding of the concepts of fluid mechanics and mining ventilation. The conclusions indicate that using simulation in pedagogical practices develops several activities that contribute to innumerable learning and expands the network of constructive meanings as a learning strategy.

Objective To explore the effectiveness of PDCA (Plan-Do-Check-Act Cycle Management) in clinical emergency blood management. Methods The data of emergency blood-using cases from January 2021 to June 2022 in each clinical department of our hospital were collected to observe the blood matching time, blood retrieving time, and emergency bloodusing rate. They were divided into PDCA experimental group (Experimental group, July to December 2021, n=287), pre-PDCA experimental group (Control group 1, January to June 2021, n=516) and post-PDCA experimental cessation group (Control group 2, January to June 2022, n=277). Subgroup analysis was performed according to different departments, which were Internal Medicine Department, Surgery Depatment, and ICU. The situation of non-emergency blood use occupying emergency lanes in the pre-implementation period was continuously improved using PDCA, and the differences in blood matching time, blood retrieving time, and emergency blood-using rate among the three groups were compared and analyzed by Kruskal-Wallis test and chi-square test. Results The blood matching time and blood retrieving time (M, min) in the experimental group, control group 1 and control group 2 were 19.00 vs 45.50 vs 23.00 and 22.00 vs 44.00 vs 25.00, respectively (P< 0.05), and were 19.00 vs 47.00 vs 24.00 and 23.00 vs 56.00 vs 30. 50 in Internal Medicine Department, 18.00 vs 57.50 vs 14.00 and 32.00 vs 41.00 vs 24.00 in Surgery Department, 20.00 vs 42.00 vs 23.00 and 16.50 vs 34.00 vs 12.50 in ICU (P

With the continuous improvement of the national education system, the Internet brings new opportunities for educational development but also brings specific challenges to the educational management of colleges and universities. This paper aims to analyze the current situation of education management in colleges and universities and construct an innovation model for education management clustering based on PDCA, which will be explored for its development value and power. And then, using the partial least squares regression algorithm and its modeling steps, to construct the educational management clustering regression model. The influencing factors of the educational management clustering model are analyzed with 12 “double first-class” colleges and universities in five provinces in Northwest China as research objects. The results show that the average comprehensive efficiency and pure technical efficiency of the universities in Northwest China range from 0.6585 to 0.9987 and from 0.773 to 0.994, respectively, indicating that the efficiency of higher education resource allocation in Northwest China is constantly improving. Compared with the traditional education management model, the colleges and universities applying the education management clustering model constructed in this paper in 2022–2023 show a scale-invariant trend, indicating that the colleges and universities have sufficiently invested in education resources and realized the scale efficiency. Educational management clustering can improve the efficiency of school educational resource allocation, thus improving the level of educational management and providing a theoretical basis for the study of innovative strategies in educational management.

The main purpose of this paper is to develop an implementation guideline for manufacturing companies integrating ISO 9001 requirements and Industry 4.0 technologies. The implementation guideline follows the Plan-Do-Check-Act model of ISO 9001 standard. We interviewed 25 experts and observed the quality management documentation of seven European manufacturing companies. Results emerged using thematic content analysis and we gained further insights from interviewees, allowing us to propose suggestions garnered from the interviews. The guideline demonstrates how requirements can be integrated with Industry 4.0 technologies such as radiofrequency identification tags, smart sensors, the internet of things, smart human interface, enterprise resource planning modules, artificial intelligence to improve a typical ISO 9001 quality management system. Some issues emerged relating to the fear of losing jobs, validation of quality control equipment based on artificial intelligence, and decision-making and problem-solving processes. The implications of this research are mainly related to the opening of a new debate concerning the integration between ISO 9001 and Industry 4.0 as well as the proposal, to our knowledge, of the first tentative integration. Manufacturing companies can use the guideline for integrating their quality management system with Industry 4.0 technologies while considering also the practical suggestions provided by the experts.

Based on the construction of berths No.9 and No.10 in the South Operation Area of Dalanping Port, Qinzhou Port, the quality control measures for underwater foundation treatment, caisson prefabrication, assembly and installation, surface structure construction, etc. were carried out through QC management methods according to the PDCA cycle in the construction of caisson gravity wharf. Feasible solutions have been proposed from six aspects: personnel, machinery, materials, methods, environment, and measurement, to address the instability of caissons caused by improper foundation treatment during the construction of gravity wharves, the large deviation of concrete component reinforcement protection layer that affects the service life of the structure, the unattractive overall shape of the wharf, and the structural safety caused by concrete cracking. It has improved the overall construction quality management level of the project, as well as the safety management level and economic benefits. [ABSTRACT FROM AUTHOR]

The article is devoted to the analysis of the definition of the quality management system (QMS) according to various sources, including the national quality standard DSTU ISO 9001:2015, the views of domestic and foreign scientists. Approaches to the definition of QMS are considered in the context of its role as a strategic decision of the organization to improve overall effectiveness and sustainable development. The authors of the article take into account the definition of Tuomi V., who sees QMS as a process management system with a focus on customer satisfaction while minimizing the cost to the organization, and also express the points of view of A. Oleshka. and Momota I.O. As a result of combining the methodological approach of Tuomi V. and the formal approach to the definition of QMS, the article proposes a new definition: QMS is a set of procedures, methods, instructions and organizational structure necessary for managing processes in order to achieve the maximum result at the minimum costs of the organization. Given the variety of approaches to understanding QMS, this new definition can become a useful tool for practical application and further research of quality management systems in various fields of activity. In addition, the article examines the development of the concept of quality and the quality management system (QMS) in international business processes. The transition period from the 80s to the 90s of the last century, when the concept of «quality» expanded its application from production processes to the sphere of services, was analyzed. The implementation of QMS in the US public sphere and the process of harmonization of national quality standards in Europe based on ISO 9000 standards are also investigated. The article also describes in detail the role of the International Organization for Standardization (ISO) in the development of international standards and the promotion of international trade. The main functions of ISO are emphasized, as well as the chronological development of ISO 9000 standards, in particular the ISO 9001:2015 version. The article also notes the research of domestic and foreign scientists who studied the implementation of international quality standards in practice at various levels, including local authorities. Auxiliary references to the works of Pakhomova T. and Lakhizha M.I., Tuomi V., who were engaged in the analysis and research of quality management systems, are indicated. The international standard ISO 9001, which defines the requirements for the quality management system, was considered. The standard provides for the ability of the organization to satisfy the needs of consumers on an ongoing basis through the effective application of the quality management system. It is general and is used in all organizations, regardless of their type, size and type of products or services. The ISO 9001 standard is based on the PDCA cycle (planning, action, verification, implementation). It provides guidance on planning, implementation, quality assessment, and continuous improvement of a product or service. The standard implementation process includes resource allocation, customer communication, internal quality audit, process monitoring and corrective actions. The author emphasizes that the implementation of the PDCA cycle in the activities of public authorities will help to improve the quality of providing public services to citizens. Completing tasks according to such a mechanism will create a high-quality precedent that can be relied upon for the implementation of subsequent projects. The introduction of quality standards will also provide a convenient basis for public managers in solving operational tasks and ensuring constructive communication with citizens. It is noted that ignoring the wishes of customers can negatively affect the profitability of the organization. The possibility of applying the methodology for assessing the quality of public services on the basis of citizens' feedback for public bodies in Ukraine is being investigated. There are two main reasons for the use of this methodology by public managers: assessment of the actual state of public service provision and prioritization of efficiency improvement processes in crisis areas of citizen service. Examples of the implementation of this methodology in other countries and research results showing the significant impact of ISO 9001 quality standards on the quality of public services are presented. It is noted that this methodology can help public managers understand the level of effectiveness of interaction between public authorities and citizens and contribute to the implementation of quality standards in areas that need it, especially in wartime.

During the 20th century, thousands of tons of munitions containing organoarsenic chemical warfare agents (CWAs) were dumped into oceans, seas and inland waters around the world. As a result, organoarsenic CWAs continue to leak from corroding munitions into sediments and their environmental concentrations are expected to peak over the next few decades. There remains, however, a lack of knowledge about their potential toxicity to aquatic vertebrates, such as fish. The aim of this study was to fill in this gap in research, by investigating the acute toxicity of organoarsenic CWAs on fish embryos, using the model species, Danio rerio. To estimate the acute toxicity thresholds of organoarsenic CWAs (Clark I, Adamsite, PDCA), a CWA-related compound (TPA), as well as four organoarsenic CWA degradation products (Clark I[ox], Adamsite[ox], PDCA[ox], TPA[ox]), standardized tests were performed following the OECD no. 236 Fish Embryo Acute Toxicity Test guidelines. Additionally, the detoxification response in D. rerio embryos was investigated by analysing the mRNA expression of five genes encoding antioxidant enzymes (CAT, SOD, GPx, GR and GST). During the 96 h of exposure, organoarsenic CWAs induced lethal effects in D. rerio embryos at very low concentrations (classified as 1st category pollutants according to GHS categorization), and were therefore deemed to be serious environmental hazards. Although TPA and the four CWA degradation products caused no acute toxicity even at their maximum solubility, the transcription of antioxidant-related genes was altered upon exposure to these compounds, indicating the need for further testing for chronic toxicity. Incorporating the results of this study into ecological risk assessments will provide a more accurate prediction of the environmental hazards posed by CWA-related organoarsenicals.
