An analysis of a cadaver with a rare anatomical variation of thyrocervical trunk

IntroductionThe course of the branches of the thyrocervical trunk (TT) such as the inferior thyroid artery (ITA), suprascapular artery (SSA), transverse cervical artery (TCA) and ascending cervical artery (ACA) has a range of anatomical variations. The available literature distinguishes between 4 to 9 types of TT variation and its branches.AimThe following paper presents an anatomical variation that was not included in any known classifications.Case studyDuring routine dissection of a body of a 84-year-old woman located in the Department of Anatomy of the University of Warmia and Mazury in Olsztyn, a following course of TT was observed. In the described case the SSA derives directly from the subclavian artery (SA), while the TT gives away ITA, ACA and TCA, which further bifurcates into two dorsal scapular arteries (DSA).Results and discussionThe analysis of the described cadaver showed that this anatomical variation of TT cannot be included in any known classification. This indicates, that it is a very rare anatomical variation of the TT.ConclusionsKnowledge of the course of the branches of TT has some significant clinical importance, inter alia during endovascular procedures, during which any mistakes may result in serious consequences for the operated patient. The most accurate understanding of the course of TT vessels and the dissemination of knowledge on this subject may reduce the risk of complications after the treatment.

The activities provided by these organizations enable them to develop and achieve the goals they set while participating in the study clubs. The results of the study may contribute to the preparation of a better offer of scientific clubs at the Faculty of Economic Sciences at UWM in Olsztyn so that it is attractive and meets the needs of students of different majors as well as possible.

Health Behaviours and the Quality of Life of Students of Medical Fields during the COVID-19 Pandemic.

(1) Background: Social distancing and closing down public spaces associated with learning, leisure and physical activity limited the spread of COVID-19. These measures had an impact not only on the economy and education but also on health behaviours and the quality of life of individuals affected by the restrictions. The aim of this study was to identify the role of health behaviours in the perception of the quality of life of students during the COVID-19 pandemic. (2) Methods: This study was conducted among 796 students of the University of Warmia and Mazury in Olsztyn in the first quarter of 2022. Subgroup 1 consisted of students at the Public Health School (n = 428; 53.8%) and subgroup 2 consisted of students belonging to the Faculty of Veterinary Medicine (n = 368; 46.2%). The diagnostic survey method was applied, and an original survey questionnaire, the Health Behaviour Inventory and the Quality of Life Questionnaire (WHOQoL-Bref version) were used. (3) Results: The largest contribution to the prediction of quality of life of students in subgroup 1 was made by a positive mental attitude related to avoiding too strong emotions, which explained 19% of the result variability in the somatic domain (ßeta = 0.24; R2 = 0.21), 20% of the result variability in the psychological domain (ßeta = 0.36; R2 = 0.20), 16% of the result variability in the social domain (ßeta = 0.52; R2 = 0.17) and 17% of the result variability in the environmental domain (ßeta = 0.19; R2 = 0.19). Moreover, in subgroup 2, a predominantly positive mental attitude significantly predicted quality of life in the somatic domain, explaining 23% of the result variability (ßeta = 0.24; R2 = 0.26), while it explained 25% of the result variability in the psychological domain (ßeta = 0.47; R2 = 0.25), 16% of the result variability in the social domain (ßeta = 0.46; R2 = 0.17) and 21% of the result variability in the environmental domain (ßeta = 0.38; R2 = 0.23). (4) Conclusions: Positive correlations between health behaviours and the quality of life among the study participants were determined. Health-promoting behaviours had a beneficial impact on the respondents' quality of life during the COVID-19 pandemic. The category of health behaviours described as a positive mental attitude was an important predictor for the participants' quality of life.

Positive Orientation and Feelings of Loneliness among Polish Students during the COVID-19 Pandemic.

Background/Objectives: The COVID-19 pandemic was a time of limited direct contact with other people. The aim of this study was to determine the role of positive orientation and sociodemographic variables in the feelings of global, social and emotional loneliness and to seek predictors for loneliness among students during the COVID-19 pandemic. Methods: The study was conducted on a group of 798 students at the University of Warmia and Mazury in Olsztyn (Poland) between January and March 2022. The empirical data were gathered with the following research tools: the Positive Orientation Scale and the De Jong Gierveld Loneliness Scale-DJGLS. Results: The study found a correlation (r = -0.370; p < 0.001) between positive orientation and emotional loneliness. The level of loneliness was significantly higher in students who greatly reduced their social contact, compared to those who reduced them moderately (p < 0.001). The intensity of social loneliness among women was lower (p < 0.001) than among men. Those who lived with their families or with a close companion felt less intense emotional loneliness (p < 0.001) than those who lived alone. Conclusions: A positive orientation, which manifests itself in a favourable opinion about oneself and in attaching weight to positive aspects of life, was found to be the main determinant of the feelings of global and emotional loneliness. However, it did not prove to be a predictor of social loneliness in the group of students under study.

Integrating Data from Terrestrial Laser Scanning and Unmanned Aerial Vehicle with LiDAR for BIM Developing

Abstract. The use of Building Information Modeling (BIM) in building construction and management is becoming increasingly common. Nevertheless, the generation of BIM models for already existing buildings is still an operation requiring a significant human effort. The generation of a geometrically reliable and complete BIM model requires geometric information on all the building parts. Since acquiring such information with a unique acquisition tool is quite hard, integration of data acquired with different acquisition tools and platforms is strongly recommended in order to obtain a geometrically complete 3D description of the building. This work presents a procedure for integrating data acquired with Terrestrial Laser Scanning (TLS), UAV (Unmanned Aerial Vehicle) LiDAR (Light Detection and Ranging) and Smartphone with LiDAR, showing the obtained results on two case studies, two buildings in the campus of the University of Warmia and Mazury in Olsztyn. Finally, a BIM model have been successfully generated in both the case studies by using the Blender software.

The Identification of Bee Comb Cell Contents Using Semiconductor Gas Sensors.

Beekeeping is an extremely difficult field of agriculture. It requires efficient management of the bee nest so that the bee colony can develop efficiently and produce as much honey and other bee products as possible. The beekeeper, therefore, must constantly monitor the contents of the bee comb. At the University of Warmia and Mazury in Olsztyn, research is being carried out to develop methods for efficient management of the apiary. One of our research goals was to test whether a gas detector (MCA-8) based on six semiconductor sensors-TGS823, TGS826, TGS832, TGS2600, TGS2602, and TGS2603 from the company FIGARO-is able to recognize the contents of bee comb cells. For this purpose, polystyrene and wooden test chambers were created, in which fragments of bee comb with different contents were placed. Gas samples were analyzed from an empty comb, a comb with sealed brood, a comb with open brood, a comb with carbohydrate food in the form of sugar syrup, and a comb with bee bread. In addition, a sample of gas from an empty chamber was tested. The results in two variants were analyzed: (1) Variant 1, the value of 270 s of sensor readings from the sample measurement (exposure phase), and (2) Variant 2, the value of 270 s of sensor readings from the sample measurement (measurement phase) with baseline correction by subtracting the last 600 s of surrounding air measurements (flushing phase). A five-time cross-validation 2 (5xCV2) test and the Monte Carlo cross-validation 25 (trained and tested 25 times) were performed. Fourteen classifiers were tested. The naive Bayes classifier (NB) proved to be the most effective method for distinguishing individual classes from others. The MCA-8 device brilliantly differentiates an empty comb from a comb with contents. It differentiates better between an empty comb and a comb with brood, with results of more than 83%. Lower class accuracy was obtained when distinguishing an empty comb from a comb with food and a comb with bee bread, with results of less than 73%. The matrix of six TGS sensors in the device shows promising versatility in distinguishing between various types of brood and food found in bee comb cells. This capability, though still developing, positions the MCA-8 device as a potentially invaluable tool for enhancing the efficiency and effectiveness of beekeepers in the future.

Wood Biomass Ash (WBA) from the Heat Production Process as a Mineral Amendment for Improving Selected Soil Properties

This research concerned the possibilities of the natural management of ash, which is a waste product obtained in the process of burning wood chips in a bio-heating plant. The basis of the research was a pot experiment, which was carried out in a greenhouse of the University of Warmia and Mazury in Olsztyn, Poland. This experiment dealt with the influence of increasing doses of wood biomass ash added to soil on selected soil properties. The soil used for the pot experiment was taken from the arable layer (0–25 cm) of the soil. It was characterized by acidic reaction, low salinity, and an average content of total carbon (TC). The test plant was corn. Soil analysis after plant harvest showed an increase in pH and a significant improvement of soil sorption properties, without causing an excessive increase in soil salinity. In addition, a significant increase in the content of available K, P, and Mg was observed, which at the highest dose of WBA reached: 121.9; 109.3, and 41.33 mg kg−1 of soil, respectively. The content of trace metals: iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), cadmium (Cd), lead (Pb), cobalt (Co), chrome (Cr), and nickel (Ni) in the soil was quite varied but did not exceed the permissible values for agricultural soils. The content of available forms of these trace metals at the highest dose of WBA was, respectively, 1004, 129.9, 8.70, 2.08, 5.54, 0.195, 1.47, 0.97, and 1.92 kg−1 of soil. The results confirmed the significant fertilizing potential of wood biomass ash.

Współpraca Uniwersytetu Warmińsko-Mazurskiego w Olsztynie z ukraińskim Uniwersytetem Pedagogicznym w Berdiańsku – krótki epizod z historii wymiany naukowej, dydaktycznej i kulturalnej

In the article, I analyse the effects of scientific, didactic and cultural cooperation between the University of Warmia and Mazury in Olsztyn (Poland) and the Pedagogical University in Berdiansk (Ukraine). After Poland’s accession to the European Union in 2004, Polish institutions of higher education became interesting potential partners for universities in independent Ukraine. Together with other universities in Western and Central Europe, they create a common educational space – a political, educational and cultural project. Scientific and educational aspirations, as well as great opportunities for creating the value of culture by the academic communities of Ukraine, have become the content of international cooperation of these universities. The University of Warmia and Mazury in Olsztyn has established 30 contacts with universities from Ukraine. In the article, I discuss the results of this cooperation with one of them – the Pedagogical University of Berdiansk.

Prevalence of low back pain among students

&lt;b&gt;Introduction.&lt;/b&gt; Low back pain is a very common G-force (Gravity-force) illness. Approximately 80% of the population suffer from low back pain at least once in their lifetime. The main causes of this condition are: an improper preparation of the spine to the erect position within the evolutionary process, weak muscles and a lack of basic knowledge concerning the biomechanics of the human body. Low back pain most frequently affects people at the working age, i.e. from 30 to 60 years old. It has been observed that low back pain tends to be recurring and frequently becomes chronic. &lt;b&gt;Aim.&lt;/b&gt; The aim of this study was to analyse the prevalence of low back pain in the group of 40 students. This group was selected for the research because of their lifestyles which may contribute to the appearance of low back pain. The following factors were analysed: causes of low back pain, its frequency and intensity. &lt;b&gt;Materials and methods.&lt;/b&gt; This study involved a group of 40 third year students of Nursery at the Faculty of Medical Science of the University of Warmia and Mazury in Olsztyn. The selected students were between 21 and 27 years of age. The questionnaire method was applied to carry out the research. &lt;b&gt;Results and conclusions.&lt;/b&gt; The obtained results indicate that the age of people who suffer from low back pain is dropping. 75% of the respondents, aged between 21 and 27, manifested low back pain. The risk factors for such ailments include: additional work, sitting lifestyle and mental exhaustion. The presence of low back pain was connected with: G-force (Gravity-force) – in 35.09% of the cases, work – 21.05% of the cases, standing for a long time – in 21.05% of the cases. The frequency of low back pain was high in 50% of the cases, i.e. the respondents experienced pain several times a month. 50% of the respondents suffered from low back pain more often than once a month, 30% once a month, and the remaining 20% less frequently. The intensity of low back pain amounted, on average, to 4.17 points in the visual–analog scale. The obtained results should not be generalized. Further research needs to be carried out involving a bigger group of people and the results should be verified.

Księgozbiór Johanna Graumanna (1487–1541) w zbiorach Biblioteki Muzeum Warmii i Mazur w Olsztynie – charakterystyka kolekcji

The library of the Museum of Warmia and Mazury in Olsztyn has a rich collection of old prints. Among them, volumes once belonging to the Königsberg preacher Johann Graumann (1487–1541), known under the pseudonym Poliander, have been identified. There are 28 volumes with 157 bound titles. The theologian’s private library numbered nearly 1,000 copies. After his death, it was handed over to the care of the Königsberg City Council. In accordance with his will, the volumes initiated the Königsberg City Library (Stadtbibliothek Königsberg). After the end of the Second World War, the Königsberg book collection was dispersed. As a result of a campaign to secure cultural property in the former East Prussian territories, several dozen volumes of Königsberg provenance found their way to the MWiM Library in Olsztyn. The rest of J. Graumann’s book collection was transported, among others, to the University Library of the Nicolaus Copernicus University in Toruń.

Zwrotna informacja zwrotna: co o feedbacku nauczyciela myślą uczniowie i co z tego wynika?

"The aim of this article is to investigate the influence of certain types of feedback on the student’s positive and negative emotions. The authors consider feedback within the framework of the constructivist-humanistic approach to education, emphasising the teacher’s role of guiding the learner through the learning process and their responsibility to cultivate a growth-promoting climate in order for learning to occur, which may be achieved through appropriate forms of feedback. As the role of emotions had become more prominent in educational discourse, the notions of Foreign Language Classroom Anxiety and Foreign Language Enjoyment were proposed to describe the respective negative and positive emotions emerging in the classroom. The influence of feedback on those sets of emotions was measured in an online study employing qualitative research, which was distributed among 173 English Philology students of University of Warmia and Mazury in Olsztyn, the Maria Curie-Skłodowska University in Lublin, University of Łódź, University of Warsaw and University of Gdańsk. The first open-ended question concerned the fondest memory of receiving feedback and whether that feedback was general or specific. The aim of the second open-ended question was to examine the most stressful feedback, and whether it was oral or written in form. The findings allowed the authors to formulate appropriate conclusions and propose a number of pedagogical implications."

Planowanie zajęć dydaktycznych na studiach wyższych w okresie pandemii

The article focuses on the issue of preparing the schedule of didactic classes in the conditions of social isolation and sanitary regime during the COVID-19 pandemic at universities in Poland. The research was conducted at the Faculty of Social Sciences, University of Warmia and Mazury in Olsztyn, based on individual interviews, partially directed, with employees responsible for planning in 2017 2021, analysis of existing databases, i.e. state-wide regulations and intra-university regulations. To elaborate on the subject, an outline of the pre-pandemic timetable preparation process was outlined and compared with planning in times of complete isolation and recovery to relative normality in a sanitary regime. The preparation of a relevant timetable of didactic classes, taking into account study plans for individual fields of study for the entire education cycle, is a time-consuming and responsible work, in which the margin of error should be minimized in: overlapping the implementation of didactic units and hourly miscalculation of individual subjects. This task in the period of isolation and relative stabilization in the sanitary regime was a huge challenge for planners, who often had to react to a dynamically changing pandemic situation. Inefficient preparation of timetables can significantly disrupt the organization of the didactic process in higher education.&#x0D;

Cutaneous Adverse Drug Reactions (CADRs)-Statistical Analysis of the Causal Relationship between the Drug, Comorbidities, Cofactors, and the Cutaneous Reaction-A Single-Centered Study.

Cutaneous adverse drug reactions (CADRs) are among the most common types of drug hypersensitivity reactions. The purpose of this study was to evaluate the clinical spectrum of CADRs and to determine the causal relationship between drugs, comorbidities, cofactors or concomitant symptoms, and cutaneous reactions. A retrospective hospital-based study was carried out over a period of 10 years at the Department of Dermatology, Sexually Transmitted Diseases and Clinical Immunology at the University of Warmia and Mazury in Olsztyn to record various CADRs, comorbidities, cofactors, and the suspected drug in hospitalized patients. The data were subjected to statistical analysis. CADRs were diagnosed in a total of 140 patients, 32.14% of whom were men and 67.86% of whom were women. The mean age was 66.33 years. The most commonly suspected drugs were Allopurinol 12.86%, Amoxicillin with clavulanic acid 10%, Amoxicillin 9.29%, Paracetamol 6.43%, Metronidazole 5%, and Carbamazepine 5%. Attention should be paid to the possibility of using a substitute for a suspected drug if CADRs arise, or discontinuing a drug that is unjustifiably overused. The results of the present study should also prompt research into a potential treatment that could be implemented concurrently with a drug that has a high predisposition to cause CADRs.

Possibilities of Adapting the University Lecture Room to the Green University Standard in Terms of Thermal Comfort and Ventilation Accuracy

Numerous classrooms at the University of Warmia and Mazury in Olsztyn, built in the years 1960–1980, require deep modernization to implement the idea of the green university there. The paper presents an energy analysis of possible scenarios of modernization of a selected lecture hall and an indication of the optimal variant in terms of the user’s thermal comfort. The conditions of the room were experimentally measured. Authors compared the energy effects of typical thermorenovation activities, such as increased thermal resistance of external walls (reduction of the primary energy (EP) demand by about 45%), with more advanced measures, such as replacement of natural ventilation with mechanical with heat recovery (indicated in the course of numerical studies as necessary for health and comfort of users). The authors also compared the effectiveness of the heat network and individual sources that could be implemented in the building. The heat pump, in combination with photovoltaic panels, turned out to be optimal (reduction of the EP by 97%, utility energy by 69%). As the problem of modernizing facilities to a similar standard is also faced by many campuses, school facilities, and assembly rooms in Central and Eastern Europe, the presented results can be a reference point for similar activities in other locations.
