Assessment of the operational facilities and hygienic practices of abattoirs and butcher shops in Ethiopia

Most meat-borne outbreaks are attributed to contamination due to poor handling practices and incomplete operational facilities in the meat supply chain. A cross-sectional study, using a structured questionnaire interview and observational checklist, was conducted to assess the hygienic practices of workers from abattoirs and butcher shops and the operational facilities in the area. A total of 286 randomly selected workers from 236 butcher shops and 3 abattoirs participated in this study. The results showed that at the abattoirs, isolation pens for sick animals, stunning boxes, separate rooms for carcass and offal, cooling equipment, and laboratories were missing facilities. Inhumane stunning, inadequate hand washing, insufficient trained workers, irregular medical checkups, and unspecified roles in the slaughtering process were practices that led to the unhygienic handling of meat. At butcher shops, hand washing after meat handling (97.9%), storing leftover meat in refrigerators (80.9%), concrete/tile floors (94.5%), and white-painted walls were good practices observed. Displaying meat at room temperature, wrapping meat with plastic bags, and newspapers, and untrained workers (82.6%) were practices that could compromise the quality of meat. Training was the only factor significantly associated with the hygienic practice of workers both at abattoirs (p = 0.023) and butcher shops (p = 0.012). Our study identified substandard facilities and unhygienic practices both at abattoirs and butcher shops that lead to microbial contamination of meat, which could be enhanced through improving operational facilities, training, and implementation of quality control systems.

Implementation of quality control systems based on machine vision and web technologies

The development of Computer Vision technologies has seen widespread adoption in various fields over the last time, including medicine, manufacturing, transportation, logistics, agriculture, and chemical industry. Research analysis indicates that Computer Vision and its practical implementation, known as Machine Vision, are widely used for defect detection in production and equipment. Despite significant research progress in this field in recent years, many unresolved issues remain concerning the quality and dimensions of input data, selection of image recognition models and their training, and the accuracy of results. Integration of machine vision system elements for information exchange and decision-making poses a significant challenge. This paper presents one approach to addressing this issue. The aim of the paper is to explore the implementation approach of quality control systems using web technologies. The task of detecting defects in printed circuit boards (PCBs) is common in many manufacturing processes. PCB inspection involves comparing the current PCB sample with a defect-free reference. Essentially, this task involves comparing two images and identifying differences between them. Defect recognition is based on the Structural Similarity Index (SSIM), which computes the degradation component reflecting the difference between images and the similarity component. The SSIM metric is already implemented in image processing libraries. This work utilizes calculations using OpenCV and scikit-image image libraries. To automate the PCB comparison process and address deployment and integration challenges at the SCADA level, a web application has been developed. This web application allows users to select a reference PCB image and upload the current PCB image for inspection. For the client-side implementation, Vue.js was chosen due to its popularity and efficiency in developing web interfaces, particularly Single Page Applications (SPAs). Vue.js's reactive system ensures automatic updates to reflect changes in data state. For the server-side implementation, Flask – a Python framework, was used, facilitating integration with the PCB comparison algorithm as both utilize Python. According to the available features, operators can upload two images – a reference PCB image and the PCB image to be compared with the reference. After uploading, the images are displayed in the system interface. On the server side, the received data is decoded and compared using the appropriate algorithms. After comparison, the results are encoded in base64 format and sent back to the client-side for display, allowing the operator to assess the similarity or differences between the PCBs. The application can operate in both automatic and manual modes. Therefore, an analysis of the challenges encountered in implementing and deploying quality control systems based on computer vision methods has been developed. The use of web technologies, particularly Python frameworks, for integrating developed models is proposed. This approach is demonstrated using the example of PCB defect recognition tasks.

Information system of polyethylene quality control in the circular economy

Polyethylene quality control system is a set of methods and means of control and regulation of components that determine the level of product quality, as well as technical control at all stages of the production process. The first experience of polymerization of polyethylene at the end of the XIX century was received by the scientist Gustavson. For many years, polyethylene was created in small quantities, but in 1938 the process of industrial production was mastered by the British. At that time, the polymerization method was not yet perfect and required additional means of production control. Nowadays, each company uses different methods to control production, but given the complex chemical and technological processes, the need for a more efficient and integrated system that will control the quality of final products and at the same time save raw materials is still relevant.

Assessment of Hygienic Practices in Beef Cattle Slaughterhouses and Retail Shops in Bishoftu, Ethiopia: Implications for Public Health.

Understanding the potential drivers of microbial meat contamination along the entire meat supply chain is needed to identify targets for interventions to reduce the number of meatborne bacterial outbreaks. We assessed the hygienic practices in cattle slaughterhouses (28 employees) and retail shops (127 employees) through face-to-face interviews and direct personal observations. At the slaughterhouses, stunning, de-hiding and evisceration in vertical position, carcass washing and separate storage of offal were the identified good practices. Lack of hot water baths, absence of a chilling room, infrequent hand washing, insufficiently trained staff and irregular medical check-up were practices that lead to unhygienic handling of carcasses. At the retail shops, cleaning equipment using soap and hot water (81%), storing unsold meat in refrigerators (92%), concrete floors and white painted walls and ceilings were good practices. Adjacently displaying offal and meat (39%), lack of a cold chain, wrapping meat with plastic bags and newspapers, using a plastic or wooden cutting board (57%), infrequent washing of equipment and floors, and inadequately trained employees were practices that could result in unhygienic handling of beef. Our study identified unhygienic practices both at the slaughterhouses and retail shops that can predispose the public to meatborne infections, which could be improved through training and implementation of quality control systems.

The article deals with the Austrian state policy in the area of professional training of pedagogical personnel. Its objective is to analyze the key priorities of Austrian state policy in the field of vocational education of teachers, which are reflected in the legal framework of the pedagogical education and the national concept of its reform. In order to achieve this objective such theoretical methods as analysis, interpretation, generalization of scientific literature on the research problem and Austrian legal documents on the professional training of pedagogical staff have been used. First of all, on the basis of the analysis of research works of Austrian scientists and Austrian national reports on education the most problematic aspects of the professional training of pedagogical personnel (insufficient integration into the international educational space, discrepancy with the current realities of educational practice, structural and organizational differences, irrelevance of content and technology, etc.), have been generalized in the article. These problems have actually intensified Austrian government activities in the field of systemic reform of pedagogical education. Then in consequence of the study of legal documents the main priority directions of Austrian state policy in the area of pedagogical education (internationalization, standardization, academization, professionalization, etc.) have been identified and the system of reform measures (elimination of status inequality of different groups of pedagogical staff, diversification of specialties of pedagogical education, realization of the three-cycle degree structure, implementation of quality control system, etc.) has been considered. As a result of the research has been made the conclusion about the prudence, consistency, flexibility, prospective and anticipative character of the modern Austrian state policy in the field of pedagogical education that provides preconditions for qualitative professional training of new generations of teachers with abilities and competencies for an effective professional activity in the conditions of the 21st century. Keywords: pedagogical education in Austria, professional training of teachers, state policy, legislative framework, directions for reform.

Current status of breast cancer screening in the world

The mortality associated with breast cancer is decreasing in Europe and the United States. There are various reasons for these trends, including an increase in detection of early-stage breast cancers due to increased use of mammographic screening and the establishment of standardized systemic treatments based on evidence-based medicine. However, in Japanese women, both the morbidity and the mortality of breast cancer are increasing. In this manuscript, we describe the current status of mammographic screening in Europe and the United States, and the status of breast cancer screening in Japan. Quality control systems are also introduced, and the need for practical measures, such as implementation of quality control systems aimed at improving the cancer screening rate (with a target of 50%) and population-based screening (organized screening), based on the Cancer Control Act, is described. Current countermeasures for dense breasts in women in their 40s, both overseas and in Japan, are also described, together with discussions of the diagnostic capability of digital mammography, the usefulness of screening combined with computer-aided diagnosis, and the current status of screening using MRI in Europe and the United States.

Preparation of an estuarine sediment quality control material for the determination of trace metals

Quality Control Materials (QCM) have being used routinely in daily laboratory work as a tool to fill the gap between need and availability of Certified Reference Materials (CRM). The QCM are a low-cost alternative to CRMs, and they are in high demand, especially, for the implementation of quality control systems in laboratories of several areas. This paper describes the preparation of a QCM for the determination of trace metals in estuarine sediments and the results of an interlaboratory exercise. Homogeneity and stability studies were performed and analysis of variance was carried out with the results. No statistical significant differences were observed in the concentrations of Co, Cr, Cu, Mn, Pb and Zn between- or within bottle results. Neither the storage nor temperature affected the results. Therefore, the QCM produced is considered homogeneous and stable and can be used for statistical control charts, evaluation of reproducibility and interlaboratory exercises.
