Development is an integral part of research, since the study of specifics and characteristics in such a unique topic as the quality of processed products cannot be done without extraordinary equipment, fixtures and a laboratory. Laboratory equipment has been created that combines all hardware aspects of the development of the quality of processed products, where it analyzes the quality of workpieces that depend on the processing technology. However, this depends largely on the technological system used. The paper includes measurements, data acquisition and back-checking of the logic of the study of grinding operations. In the introduction, it must be shown that the correct selection and strength characteristics of the tool associated with the cutting mode of grinding determine the accuracy and quality of the surfaces of the ground part. The impact on the service life of the grinding tool was also monitored. The 4th partial result is also the knowledge that the correct selection of the tool characteristics and cutting mode predicts the quality of the workpiece surface. The operating conditions of the manufactured parts significantly affect the operating values of the production parameters. By appropriate diagnostics in the research process and precise measurements using sensitive sensors, deviations can be minimized. Without this apparatus, it is possible that deviations increase significantly during the operation of the technological system. The size of the deviation during grinding is explained in practice by the presence of vibrations in technological processes. They cause instability of the parameters of the technological system. To stabilize the quality indicators, a mathematical apparatus was also used, which takes into account changes in the technological regime. They are determined by designing adverse conditions, e.g. restoration of the cutting properties of a worn grinding wheel. Therefore, its replacement is logically carried out earlier than its replacement is planned.

The contemporary market for products and services is marked by intense and continually in-creasing competition, ongoing economic and technological shifts, and customers who are steadily more demanding and informed. The growing competition and the awareness of the 21st century customers require to link the new and more aware customer requirements with innovation in the services sector. The best source of information regarding changing demands comes from customer feedback, which guides modifications aimed at enhancing quality. Through their level of satisfaction, the customer imparts information about the extent, nature, and range of innovation required to fulfil their expectations. The article suggests a model util-ising the Servqual method, which helps to indicate sectors within service enterprises that re-quire modification or advancement, as well as the essence and category of said alterations. Suggestions for innovation are linked with the maximum value of the calculated indicator (RAi). The analysis of the data shows that the greatest scope for enhancement is in the E1 enterprise, where RAi in all domains exceeds the value of 30. The second business which requires quick alterations is E6. Two companies (E1 and E3) require innovation in the area related to “responsiveness.”

The foundry industry is an important component of the economy on which other progressive industries depend. The reliability of the products it manufactures is determined by the technologies used, but, most importantly, it ensures the expected level of quality. The purpose of the article is to develop a synergistic quality-cost model for the improvement of casting products. The model is based on an integral methodological configuration that makes it possible to determine the level of relevance of the causes of casting nonconformity in the quality-cost context. The model integrates techniques such as the Pareto-Lorenz diagram, ranking, brainwriting, Ishikawa diagram, Likert rating scale, and matrix diagram. Verification of the method by its implication in the manufacturing process of a gearbox casting is performed. The model makes it possible to identify quality-cost relationships between key categories of problem causes and major product nonconformities. The main causes of the loss of quality stability of the analyzed product are found to be low quality of molding sand, poor technical condition of foundry equipment (too infrequent repairs and overhauls), and ineffective quality control. Carrying out the analysis made it possible to develop appropriate improvement measures. It is proposed to implement changes in the casting process, implement the TPM method, conduct periodic training, develop job instructions, implement a control system, and provide supervision of employees. Further research directions will concern the implications of the method within the other positions in the casting company and its development towards automation of analysis.

A market economy requires continuous improvement of products. The classic case is striving to meet customer expectations, i.e., ensuring product quality. However, in terms of sustainable development, it is also necessary to take actions that contribute to the protection of the natural environment and ensure a positive social impact. It is still a challenge. Therefore, the aim of the article is to develop a model for product improvement by considering the criteria of quality, environment, and social impact. The developed model is an original decision indicator, according to which prototypes of modified products are ranked according to their fulfillment of (i) expected quality, (ii) low environmental impact in the life cycle (LCA), and (iii) social responsibility. Based on the results of the model and the proposed decision indicator, it is possible to determine the direction of improvement of any product by assessing prototypes (product variants) in terms of their sustainable development. The model test is carried out for photovoltaic (PV) panels, popular in recent years, verified according to six prototypes and 15 sustainability criteria regarding their quality, environmental impact, and social responsibility. The test confirmed its effectiveness in the case of photovoltaic panels, but the proposed model can be successfully used to design or improve other products. This is supported by a developed original decision indicator supporting the making of multicriteria quality, environmental, and social decisions at the stage of designing new products or improving existing products.

Purpose: Improving the quality of medical services is one of the key focus areas of hospital management. The search for opportunities for improvement, addressing real problems and meeting the needs of customers becomes particularly important in the face of such challenges as technological, especially the development of digitization and e-medicine, demographic changes, including, among others, aging societies, political and financial. The study was conducted to identify and analyze staff attributes that determine the achievement of a level of patient satisfaction with the quality of hospital services. Design/methodology/approach: Based on desk research and interviews with patients of a sample hospital, six key staff attributes important for achieving satisfaction with the quality of hospital services were identified. These attributes were subjected to empirical studies conducted in accordance with the methodology of the Kano model (first stage) and the survey method (second stage). The results of the studies made it possible to identify gaps between the highest desired degree of satisfaction and the level resulting from the patients' actual evaluation. Subsequently, the authors formulated their own recommendations for strengthening human capital for increasing the quality of hospital services. Findings: Based on the research, the map of key staff attributes affecting patient satisfaction with the quality of hospital services was developed. The attributes with the greatest importance and strength of influence on the quality of services, characteristic of the three professional groups studied, were then identified. Among them were: professionalism, kindness and politeness towards the patient and his family members, individualized approach to the patient. Recognizing the opinions of patients of a particular hospital, the attributes that were important but at the same time rated lowest were identified. On this basis, gaps between the expected and actual state were identified, and suggestions were made for improvement in the areas of knowledge, communication and cooperation. Research limitations/implications: Some limitations were recognized in the research process, primarily due to the size of the research sample and the scope and scale of empirical research. It seems desirable to expand the research field to include the international environment. Conclusions made against the background of other cultural or systemic conditions of health care in a given country could enrich the conducted comparative analysis with interesting insights. In addition, the study of correlations between an expanded set of factors influencing the quality of hospital services and the level of patient satisfaction could provide a direction for further research. Practical implications: The results of the study may be of interest to stakeholders in the health care industry. Identifying the key personnel attributes of greatest importance and power to influence service quality seems important for designing changes that strengthen a hospital's human capital. The presented suggestions for improvement in the areas of knowledge, communication and cooperation based on the results of patient satisfaction surveys of a specific hospital have application value. Social implications: Implementation of changes designed on the basis of the research results presented and suggestions for improvement in the areas of knowledge, communication and cooperation can realistically improve patient satisfaction with the quality of hospital services. In addition, hospitals' interest in improving the quality of services in response to patients' needs and expectations demonstrates social responsibility. Originality/value: The paper identifies key staff attributes important for achieving patient satisfaction with the quality of hospital services. It also provides practical recommendations for improvement in the areas of knowledge, communication and cooperation. The article is dedicated to academic and healthcare professionals, including hospital managers, as well as local government administration.

Purpose: The aim of the article was to develop a QLCA framework model dedicated to the design and improvement of products, taking into account their quality (Q) and environmental impact in the life cycle (LCA). Design/methodology/approach: A review of the literature on the subject was conducted on studies from the Web of Science database. The thematic scope included the design and improvement of products, taking into account quality and environmental impact during the life cycle (LCA). Bibliometric and frequency techniques were used, including keyword analysis and citation of studies. Based on conclusions from the literature, approaches and methods for quality improvement, as well as the LCA methodology presented in the ISO 14040 standard, a QLCA framework model was developed. The model supports the prospective assessment of the quality and life cycle of the product and its prototypes in terms of sustainable development. Findings: It has been shown that there are no solutions that present the links between product life cycle assessment and product quality assessment, including preparing these assessments for product prototypes at the design and prototyping stage. Research limitations/implications: A QLCA framework model is presented, the proper form of which will be provided by future research. The framework conditions of the QLCA model were improved and expanded in order to find the most advantageous approach to achieving the highest quality product quality with the lowest possible negative environmental impact of this product in LCA in terms of its sustainable development. Practical implications: The QLCA framework model is the result of conceptual generalisation, and its assumptions were prepared for designers and R&D departments. The assumptions of the QLCA methodology can be used by management staff to make decisions about product improvement at the prototyping stage. Originality/value: A novelty is the QLCA framework model, which presents an original approach to product improvement at the prototyping stage, taking into account customer expectations regarding their quality and at the same time assessing the life cycle of these prototypes.

Purpose: The idea of the study is to understand fluctuation in quality management depending on organizational context. The primary purpose of this article is to analyze changes in quality management in four countries grouped in V4 (The Visegrad Group) in the prism of macroeconomic crises, over the last five years. The following research question was formulated: What influences market saturation with a formal approach to quality management (ISO 9001 certificates), and when? Design/methodology/approach: The considerations are based on a systematic literature review (SLR) and an analysis of the long-term data of ISO survey – certifications. The data was compared among V4 countries and an attempt was made to relate the results to economy-wide indicators, especially in turbulent environments. Findings: The results show no clear and unidirectional relationships between the number of ISO 9001 certifications and macroeconomic data. This was identified for the V4 group as a whole and for individual countries, as well. Implementation of the QMS is an individual decision of each organization, depending on closely related microeconomic factors. Research limitations/implications: Research findings always represent a slice of a larger reality. In that research paper limitations concern: the period of analysis, literature review in English and supplemented locally in the native languages, focusing on the V4 area. Findings implicate quality management’s perceptions need to adjust the lens to understand macro numbers of certificates by the circumstances and adjust micro decisions in organizations in the QM area depending on the crisis phase on the market.Originality/value: The article analyses certification data in previously unpresented form. Results were compared between V4 countries in the prism of times of crisis with an indication of certificate saturation rates and an attempt to explain macroeconomic fluctuations. The research results are helpful for researchers exploring quality management issues, and all organizations that can relativize the importance of quality management.

Kluczowym procesem pozwalającym zapewnić stabilność parametrów jakościowych produkowanego węgla i koksu jest proces rozpoznania złoża, pozwalający na osiągnięcie zamierzonego poziomu jakości poprzez odpowiednie harmonogramowanie ścian w aspekcie jakościowym. Jastrzębska Spółka Węglowa by sprostać wymaganiom rynku ciągle udoskonala swoje procesy w tym te związane z rozpoznaniem złoża i planowaniem produkcji. Wskaźniki reaktywności i wytrzymałości poreakcyjnej koksu są parametrami krytycznymi dla wydajnej pracy wielkiego pieca, niestety nie zawsze możliwe jest ich oznaczenie dla próbek geologicznych. W artykule omówiono możliwość zastosowania metod uczenia maszynowego w procesie prognozowania parametrów jakości koksu określanych testem Nippon Steel Corporation (NSC). W celu analizy danych i budowy modeli predykcyjnych wykorzystano oprogramowanie RapidMiner, które umożliwiło skuteczną eksplorację danych, budowę modeli oraz analizę wyników. Analiza historycznych danych geologicznych z pomocą popularnych technik uczenia maszynowego pokazała, że prace nad zastosowaniem sztucznej inteligencji w prognozowaniu jakości złoża są perspektywiczne i należy dążyć do identyfikacji najbardziej efektywnych podejść do tego zagadnienia.

The key process for ensuring the stability of the quality parameters of the coal and coke produced is the process of bed reconnaissance, which allows the intended level of quality to be achieved through appropriate long-wall scheduling in terms of quality. To meet coal market demands, Jastrzębska Spółka Węglowa is constantly improving its processes, including those related to deposit reconnaissance and production planning. Coke reactivity and coke strength after reaction are critical parameters for efficient blast furnace operation; unfortunately, determining them for geological samples is not always possible. This paper discusses the possibility of using machine learning methods to predict coke quality parameters determined by Nippon Steel Corporation (NSC). RapidMiner software was used to analyze the data and build predictive models, which enabled efficient data mining, model building, and analysis of the results. Analysis of historical geological data with the help of popular machine learning techniques showed that work on applying AI in bed quality prediction is promising, and efforts should be made to identify the most effective approaches to this issue.

Wieprzowina od lat jest mięsem chętnie spożywanym przez konsumentów w Polsce, jak i w Europie. Poza konwencjonalnymi – intensywnymi metodami produkcji żywca wieprzowego można wyróżnić produkcję ekologiczną, do której preferowane są zwierzęta ras rodzimych. Jakość tak pozyskiwanego mięsa jest oceniana wysoko, z jednej strony ze względu na potwierdzony w badaniach i ocenie laboratoryjnej charakter prozdrowotny mięsa, ale również ze względu na uzyskiwany wyraźny jego smak. W Polsce utrzymuje się trzy rasy rodzime świń, do których należą: rasa puławska, rasa złotnicka pstra i rasa złotnicka biała. Stan pogłowia świń tych ras nie jest wysoki, wyjątek stanowi rasa puławska, ale wszystkie one podlegają ochronie zasobów genetycznych. Ochrona zwierząt tych ras prowadzona jest w szczególności by zachować pulę cennych genów, których wartość kształtuje się odmiennie od ras intensywnie użytkowanych. Celem niniejszego opracowania była analiza jakości i przydatności do spożycia mięsa pozyskanego od świń ras rodzimych.

Pork has been a meat that has been eagerly consumed by consumers in Poland and Europe for years. Apart from conventional, intensive methods of pig production, ecological production can be distinguished, in which animals of native breeds are preferred. The quality of meat obtained in this way is highly valued, on the one hand due to the health-promoting nature of the meat confirmed in research and laboratory evaluation, but also due to its distinct taste. Three native pig breeds are kept in Poland, which include: the Puławska breed, the Złotnicka Spotted breed and the Złotnicka White breed. The number of pigs of these breeds is not high, the Puławska breed is an exception, but all of them are subject to the protection of genetic resources. The protection of animals of these breeds is carried out in particular to preserve the pool of valuable genes, the value of which is different from that of intensively used breeds. The aim of this study was to analyse the quality and suitability for consumption of meat obtained from pigs of native breeds.

Measuring instruments, force transducers, control devices and various electromechanical equipment are characterized by high accuracy based on control induction supports. As in any electrical equipment, magnetic and copper losses are an undesirable factor, since this reduces the stability of the input-output characteristic and the quality factor, and increases errors. With known dimensions of magnetic conductivity and windings of the control induction winding, as well as physical and technical characteristics for known values of temperature rises, parameters can be calculated. In the presented work, expressions for size ratios are considered.

Access to recreational areas is particularly important in the context of improving the quality of life in cities. One of the valuable elements of such areas may be water reservoirs and their accompanying springs. An example of such a recreational area is the so-called Palowice Lake District (southern Poland), which includes three water reservoirs, ten breeding ponds and two springs from which water is taken. Water from the springs is considered to be of very good quality and is regularly consumed by residents of nearby towns as well as tourists. The quality of these waters is influenced by natural factors such as weathering of rocks, evapotranspiration, atmospheric deposition, climate change, but also by anthropogenic factors such as industrial effluents, domestic activities, tourist traffic and agricultural activities. However, the results of research conducted in the area of the springs indicate the presence of E. coli and enterococci in the water. The latter are characterized by longer survival in water. Consuming such water may lead to the development of numerous digestive system diseases, hence the issue of protecting water resources in urbanized areas, including conducting representative monitoring of the quality of these waters, is extremely important.

Summary of issues and justification for taking up the topic The basic goal of the article is to emphasize the importance of Industry 4.0, which intersects with today’s reality. The fourth industrial revolution combines the concepts of classical and digital technologies, using the industrial Internet of Things. Every activity carried out using technology requires an appropriate flow of all types of information to ensure data security. The article also shows the importance of the Information Security Management System, because the amount of data processed using information technology is huge. Nowadays, society systematically shares its data without thinking about the consequences. Increasingly, personal data is equated with currency, as in order to obtain a discount or future financial benefits, data is shared regardless of the consequences. The Information Security Management System requires continuous improvement of organizations processing data about identified or identifiable persons. However, independent verificati on and consent to data processing are also extremely important.

Każde działanie realizowane za pomocą technologii wymaga odpowiedniego przepływu wszelkiego rodzaju informacji w celu zapewnienia bezpieczeństwa danych. Artykuł ukazuje również znaczenie Systemu Zarządzania Bezpieczeństwem Informacji, ilości bowiem przetwarzanych danych z wykorzystaniem technologii informatycznych są ogromne. Obecnie społeczeństwo bardzo często ujawnia swoje dane, nie myśląc o konsekwencjach. Coraz częściej dane osobowe utożsamia się z walutą, ponieważ w celu uzyskania rabatu lub przyszłych korzyści majątkowych udostępnia się dane bez względu na skutki. System Zarządzania Bezpieczeństwem Informacji nawołuje do ciągłego doskonalenia organizacji przetwarzających dane o osobach zidentyfikowanych lub możliwych do zidentyfikowania. Niezmiernie ważna jest jednak także samodzielna weryfikacja i zgoda na przetwarzanie danych.

The article presents a case of discoloration on an asphalt road surface, characterized by distinctive rusty spots on its surface. Methodical petrographic studies of aggregate samples taken from the damaged pavement were discussed, aimed at identifying the causes of the rusty spots. The research results indicated that the probable cause of these stains was the presence of ore minerals containing iron compounds. Although similar phenomena cannot be completely avoided, ongoing detailed verification of manufactured aggregates would prevent such processes. It is necessary to carefully select aggregates and control their mineral composition to minimize the presence of iron compounds.

W artykule przedstawiono przypadek przebarwień asfaltowej nawierzchni drogowej, objawiających się charakterystycznymi rdzawymi plamami na jej powierzchni. Omówiono metodyczne badania petrograficzne próbek kruszyw pobranych z uszkodzonej nawierzchni, które miały na celu identyfikację przyczyn powstawania rdzawych plam. Wyniki badań wykazały, że prawdopodobną przyczyną tych plam była obecność minerałów nieprzezroczystych (rudnych) zawierających związki żelaza. Pomimo że nie da się całkowicie uniknąć podobnych zjawisk, bieżąca szczegółowa weryfikacja produkowanego kruszywa pozwoliłaby na zapobieganie takim zjawiskom. Konieczne jest staranne jego dobieranie oraz kontrola składu mineralnego, aby zminimalizować obecność związków żelaza.
