Opis:
W artykule przedstawiono rezultaty prac nad atypowymi kierunkami studiów (wyniki wcześniejszych badań zostały zaprezentowane w Rocki 2018b, 2018c, 2022a). Celem badania była weryfikacja hipotezy o aktualności wniosków dotyczących wybranych kierunków studiów formułowanych pierwotnie na podstawie danych o ekonomicznych losach absolwentów po pierwszym roku od ukończenia studiów. W niniejszej analizie wzięto pod uwagę dane uzyskane pięć lat od ukończenia studiów. W toku badań porównywano zmiany wartości wybranych wskaźników wyznaczanych w ogólnopolskim systemie monitorowania ekonomicznych losów absolwentów oraz informacje z raportów Polskiej Komisji Akredytacyjnej (PKA). Analizowano kierunki sklasyfikowane jako atypowe (prowadzone w jednej lub co najwyżej kilku uczelniach). Dodatkowym celem prac była weryfikacja hipotezy o zróżnicowaniu losów absolwentów kierunków unikatowych i typowych o tożsamej nazwie (zbliżonych efektach uczenia się) oraz o wpływie migracji na ekonomiczne losy absolwentów. Potwierdziły się wyniki omawiane we wcześniejszych publikacjach Autora: część z analizowanych kierunków atypowych nie jest ceniona przez pracodawców. Ale wykazano też, że – w większości analizowanych przypadków – absolwenci kierunków unikatowych są lepiej oceniani przez pracodawców niż absolwenci kierunków typowych. Absolwenci nielicznych spośród wybranych kierunków atypowych podejmują pracę w województwach innych niż województwo studiowania. Porównanie wniosków wynikających z danych z systemu monitorowania ekonomicznych losów absolwentów z raportami PKA opracowanymi w procedurze oceny jakości kształcenia prowadzi do wniosku, że raporty PKA często są korzystniejsze dla uczelni niż wycena absolwentów na rynku pracy.
The article presents the results of work on non-traditional fields of study (as a continuation of the research described in Rocki 2018b, 2018c, 2022a). The aim of the study was to verify the hypothesis about the validity of conclusions regarding selected fields of study initially formulated on the basis of data on the economic fate of graduates following their first year after graduation, but taking into account data obtained five years after graduation. Changes in the values of selected indicators determined in the nationwide system for monitoring the economic fate of graduates and information from the reports of the Polish Accreditation Committee (PKA) were compared in the study, with focus on fields classified as non-traditional (conducted in one or at most several universities). An additional goal of the work was to verify the hypothesis about the differences in the fate of graduates of non-traditional and traditional fields of study with the same name (similar learning outcomes) and the impact of migration on the economic fate of graduates. The results discussed in the author's previous publications were confirmed: some of the analysed non-traditional fields of study are not valued by employers. However, it was also shown that in most of the analysed cases graduates of non-traditional fields of study are assessed better by employers than those of traditional fields of study. Graduates of a few selected non-traditional fields tend to take up work in voivodeships other than the voivodeship of their studies. Comparison of the conclusions resulting from the data from the system for monitoring the economic fate of graduates with the PKA reports developed in the procedure for assessing the quality of education leads to the conclusion that PKA reports are often more favourable for universities than the valuation of graduates on the labour market.

Opis:
The monograph is dedicated to a wide range of recipients interested in the digital transformation of traditional branches of economy into learning organizations, i.e. those that, in a systematic and active way, using their own experience and available information resources, optimize their business model in accordance with the industry 4.0 paradigm, maintaining competitiveness in the changing, dynamic market. The digital revolution of the raw materials consortium described in the monograph explains and documents the digital transformation that took place in the JSW mines in the years 2016÷2020. The book covered processes related to underground computerization, radio communication, monitoring of occupational safety conditions, automation and the use of advanced data analytics to make management decisions. It presents the experience gained by entire research teams in the result of realizing strategic projects for nearly four years, documenting the greatest technological breakthrough in the Polish mining industry in years. The DIGITAL TRANSFORMATION of Poland's key raw material consortium – extensively described on the pages of the monograph – on the one hand allowed for the implementation of strategic efficiency programmes such as QUALITY and EFFICIENCY, but what is equally important, it allowed for the elimination of the huge technological debt with which Jastrzębska Spółka Węglowa S.A. has been dealing with it basically since its establishment in 1993 and in the subsequent years of its operation. This debt, growing year by year, strangled the technological innovativeness of the JSW S.A., especially in the years 2000÷2015, paralyzing the implementation of advanced IT projects and not recognizing the OT area at all, the implementation of which could have significantly improved the production monitoring and control processes in the JSW mines. The book presents the Polish experience of entire teams of engineers: IT specialists, automation specialists, miners, geologists and economists, transforming the traditional branch of the economy, which is mining, into a European raw material consortium with ambitions, showing, among others: − how to build a management and supervision strategy over the production area of a modern raw materials company, − how to design the integration and automation of entire production processes and innovative IT/OT solutions in the production and commercial cycle in the field of technical infrastructure, communications, applications supporting security areas and data processing, − how to monitor the area of cybersecurity, security of systems and automation devices used in production, − how to create planning for the desired future, based on the analysis of past experience and functioning in the present and future. The systems for locating people and equipment, gasometric systems, monitoring of methane drainage networks and seismic phenomena, described in the monograph, have a significant impact on ensuring the appropriate level of safety.

Opis:
Objectives To find possible relationship between asthma exacerbation and metabolomic profile of airways, assessed by non-invasive method – free volatile organic compounds (VOCs) in exhaled air in children. Material and Methods The study included 80 children aged 4–18 years with asthma: 42 children with a min. 3 asthma exacerbations in the past 12 months, and 38 children without a history of exacerbations in the past year. During the study visit, each patient was examined, medical history (including information regarding atopy and eosinophil blood count) was taken, spirometry and fractional exhaled nitric oxide (FeNO) were tested, an exhaled air sample was taken to test for the presence of VOCs, and the patient also completed standardized form – Asthma Control Questionnaire. Volatile organic compounds were measured by combined gas chromatography coupled to mass spectrometry. Results The obtained results of VOCs were correlated with the history of the disease. The 2 gas profiles were defined and they formed 2 clinically distinct clusters (p = 0.085). Cluster 2 was characterized for children with a higher number of bronchial asthma exacerbations and worse lung function parameters (predicted percentage forced expiratory volume in 1 s [FEV1] [p = 0.023], FEV1/ forced vital capacity ratio [FVC] [p = 0.0219]). The results were independent of the age, sex, BMI, atopy (house dust mite allergy) and eosinophil blood count. Conclusions The study findings suggest that a relative group of gases may be a useful predictor of having asthma exacerbations in children. Additionally, a single FeNO value was unlikely to be clinically useful in predicting asthma exacerbations in children. The VOCs profile reflecting the metabolism of the airway epithelium and local microbiota was associated with the course of asthma, which strongly justifies further prospective validation studies.

Opis:
The gas turbine is considered to be a very complex piece of machinery because of both its static structure and the dynamic behavior that results from the occurrence of vibration phenomena. It is required to adopt monitoring and diagnostic procedures for the identification and localization of vibration flaws in order to ensure the appropriate operation of large rotating equipment such as gas turbines. This is necessary in order to avoid catastrophic failures and deterioration and to ensure that proper operation occurs. Utilizing an approach that is based on spectrum analysis, the purpose of this study is to provide a model for the monitoring and diagnosis of vibrations in a GE MS3002 gas turbine and its driven centrifugal compressor. This will be done by utilizing the technique. Following that, the collection of vibration measurements for a model of the centrifugal compressor served as a suggestion for an additional method. This method is based on the neuro-fuzzy approach type ANFIS, and it aims to create an equivalent system that is able to make decisions without consulting a human being for the purpose of detecting vibratory defects. In spite of the fact that the compressor that was investigated has flaws, this procedure produced satisfactory results.

Opis:
The paper investigates the dynamic character of pausing behaviour in foreign language writing. In a longitudinal study on Polish learners of Swedish, pause length and frequency, as well as the interplay between pause length and the development of lexical diversity, syntactic complexity, accuracy, and fluency, were investigated. According to the assumptions of Dynamic Systems Theory, intra- and inter-subject variability were analysed. The study has shown that the mean length of pauses did not change during the three-year period of second language learning; however, the frequency of pauses significantly decreased, as demonstrated by the increasing number of words written between pauses. There was a considerable variation within subjects during the entire period, and even moderate inter-subject variability was noticed. The occurrence of longer pauses was almost always interconnected with a higher level of accuracy, syntactic complexity, and fluency. This interplay, however, could only be confirmed at the individual level, showing the necessity of following the development of a second language in individuals rather than for the entire group.

Opis:
Diabetes stands as the most widely recognized acute disease globally, resulting in death when it is not treated in an appropriate manner and time. We have developed a closedloop control system that uses continuous glucose, carbohydrate, and physiological variable data to regulate glucose levels and treat hyperglycemia and hypoglycemia, as well as a hypoglycemia early warning module. Overall, the proposed models are effective at predicting a normal glycemic range from >70 to 180 mg/dl, hypoglycemic values of <70 mg/dl, and hyperglycemic value of 180 mg/dl blood sugar levels. We undertook a seven-day, day-and-night home study with 15 adults. Initially, we started with checking insulin levels after meal consumption, and later, we concentrated on how our system reacted to the physical activity of the patients. Evaluation was conducted based on performance parameters such as precision (0.87), recall (0.87), F-score (0.82), delay (26.5±3), and error size (1.14±2).

Opis:
The purpose of this study was to evaluate pain reduction as the main parameter for monitoring improvements in Health-Related Quality of Life (HRQoL) in a female patient following endovascular treatment of Pelvic Congestion Syndrome (PCS). A 38-year-old female patient with chronic intermittent, “dragging” abdominal pain, lasting more than two years, mainly in the lower abdomen, radiating to the sacral region, underwent SARS CoV-2 infection in October 2021, and COVID-19, which lasted 10 days. Eight months later, complaints of pain in the lower abdominal area, during the menstrual cycle, during prolonged standing, after sports activities and during and after intercourse, increased. The patient was compelled to begin diagnosis of these complaints due to the severe pain and concerns about whether she had contracted cancer of the cervix uteri. She was diagnosed on transvaginal ultrasound-Doppler and Angio-MR of the pelvic vessels with PCS. Treatment was undertaken at the Department of Vascular Surgery and Endovascular Interventions, St. John Paul II Hospital, Krakow, Poland. Intraoperatively, after confirmation through selective angiography, of previously diagnosed insufficiency of the left ovarian vein (LOV) and of the parametrial veins (PMV), the selective obliteration was performed with an adhesive dedicated to endovascular closure of veins and vascular malformations (Glubran®2). The range of pain intensity, according to theVisual Analogue Scale (VAS), in Exam. 1 (before surgery), was in the premenstrual period (BM) 7.0 points, which increased during menstruation (DM) or after intense activity (AIA) to 8.0 points, and occasionally during and after intercourse even to 9.0 points. These values were very high, indicating that pain significantly affected the patient's quality of life. The extent of pain severity decreased significantly in Study 2 (two months after surgery) and Study 3 (four months after surgery) and was 2.0 points in the premenstrual period (BM), which increased only slightly during menstruation (DM) or after intense activity (AIA) to 3.0 points, and decreased again to 2.0 points during and after intercourse. The patient reported that the procedure significantly and positively affected her functioning in daily life, especially in caring for a young child, which is evidence of the achievement of HRQoL improvement. Endovascular treatment for Pelvic Congestion Syndrome (PCS) was effective in reducing pain and improving the Health-Related Quality of Life (HRQoL) of a patient with PCS.

Modyfikacja stylu życia jest zalecana jako niefarmakologiczna metoda zapobiegania i leczenia cukrzycy typu 2. W celu redukcji ryzyka sercowo-naczyniowego rekomendowane jest stosowanie diety śródziemnomorskiej, diety DASH lub diet opartych na produktach roślinnych z dużą zawartością tłuszczów nienasyconych. Przedstawiono znaczenie samokontroli glikemii oraz rekomendacje dotyczące zalecanych leków przeciwhiperglikemicznych i przy dyslipidemii w celu redukcji ryzyka sercowo-naczyniowego.
The article presents topics selected from “2023 ESC Guidelines for the management of cardiovascular disease in patients with diabetes”. For the purpose of individualizing treatment strategies, the current Guidelines introduce SCORE2-Diabetes, which is a novel, 10-year cardiovascular disease risk score specific to patients with type-2 diabetes. Lifestyle changes are recommended as the fundamental nonpharmacological intervention for preventing and managing type 2 diabetes. Adopting a Mediterranean diet, DASH diet or a plant-based diet with high unsaturated fat content, is recommended in order to lower the risk of cardiovascular disease. The article presents also the importance of self-monitoring of blood glucose, recommendations for pharmacological glucose-lowering treatment and management of dyslipidaemia to reduce

Stanowi cenne uzupełnienie ukazujących się na rynku wydawniczym pozycji z obszaru badań nad bezpieczeństwem. Podjęty obszar tematyczny zawiera się w nurtach systemów wczesnego ostrzegania oraz bezpieczeństwa personalnego. Jak również może stanowić przyczynek do podjęcia pogłębionych rozważań naukowych w obszarze oddziaływań informacyjnych. Niektóre fragmenty analizowanej monografii mogą pozwolić zgłębić mechanizmy wojen informacyjnych, czy mechanizmy propagandy. Temat ten może być przydatny w wielu obszarach, a najnowszy, jak to doświadczenia z wojny Rosji z Ukrainą, gdzie istotnym elementem tego konfliktu jest wojna informacyjna, której podstawowym czynnikiem jest zniekształcanie przekazywanych informacji. A najdobitniejszym przykładem tego, co może spowodować zorganizowane oddziaływanie informacyjne jest społeczeństwo rosyjskie i wysoki odsetek mieszkańców Rosji popierających tę wojnę. Podjęte w niniejszej monografii problemy mogą wpłynąć również na odporność, w odczycie informacji i sygnałów podawanych w różnych środkach przestrzeni społecznej. Takim obszarem są media społecznościowe i zjawiska różnych form agresji informacyjnej w tych mediach.

Opis:
In this comprehensive study, the concept and structural diagram of the system for diagnostics of induction electric motors of vehicles with the development of algorithms for the operation of modular units for monitoring the state of the main structural elements are proposed. During the development of the diagnostic system, the peculiarities of the construction of diagnostic systems of rotating electric machines were investigated in the real conditions of their operation, and modern methods of current and vibration diagnostics were implemented. The work algorithms of each module are presented in the functional diagram of the general diagnostic system of and cover important defects of induction motors. The diagnostic system combines methods that use different diagnostic principles and criteria and are adapted for use in an embedded diagnostic system. The developed functional diagram of the diagnostic system can be used for practical implementation in physical form. The use of the proposed diagnostic system will make it possible to obtain continuous information about the state of both electrical and mechanical components of the induction motor when operating under load with a poor-quality power system in real operating conditions.

Opis:
This article presents the upgraded Organic Multilevel Model 2.0 (OMM2) initially proposed by Oller in 2016. OMM2 underlines organic analysis principles, focusing on dynamic, comparative and diverse perspectives. It offers a methodology tailored for studying communication and media in developing nations, especially those with evolving intermedia journalistic cultures, emerging or fragile democracies, and autocratic governance. Particularly applicable to nations recently joining the EU, like those in Southern, Central, and Eastern Europe (SCEE), OMM2 aids in analyzing journalism, media monitoring, and political communication in these regions. These countries, often characterized by political upheaval and historical events like colonialism (e.g., Eastern Bloc), are the focus of the MEDIADELCOM project. Media assessment entities in these areas are part of a larger network encompassing diverse societal facets. In the SCEE context, deliberative communication signifies collective decision-making through public discourse, recognizing diverse opinions. Utilizing OMM2 for a comparative study of media monitoring is crucial to comprehend deliberative discussions in these EU-associated European democracies.

Opis:
This paper continues work from part 1 where a high precision estimator for energy efficiency and indoor environment based on artificial neural networks (ANN) was examined. Part 1 demonstrated that creating a precise representation of a mathematical relationship one must evaluate the stability and fitness under randomly changing initial conditions. Now, we extend our requirements for the model to be rapid and precise. At the end of this work we obtain a road map for the design and evaluation of ANN-based estimators of the given performance aspect in a complex interacting environment. This paper also shows that ANN system designed may have a high precision in characterizing the response of the building exposed to variable outdoor climatic conditions. The absolute value of the relative errors, MaxAR, is less than 2%. It proves that monitoring and ANN-based characterization approach can be used for different buildings, including those with the best environmental performance.

Opis:
The tracking of moving objects with the use of GPS/GNSS or other techniques is relied upon in numerous applications, from health monitoring and physical activity support, to social investigations to detection of fraud in transportation. While monitoring movement, a common subtask consists in determining the object’s moving periods, and its immobility periods. In this paper, we isolate the mathematical problem of automatic detection of a stop of tracking objects under the stream processing regime (ideal data processing algorithm regime) in which one is allowed to use only a constant amount of memory, while the stream of GNSS positions of the tracked object increases in size. We propose an approximation scheme of the stop detection problem based on the fuzziness in the approximation of noise level related to the position reported by GNSS. We provide a solving algorithm that determines some upper bounds for the problem’s complexity. We also provide an experimental illustration of the problem at hand.
