Machine learning based geometry reconstruction for quality control of laser welding processes
Authors: Hartung Julia , Jahn Andreas , Heizmann Michael
Published: May 2023

The increasing use of automated laser welding processes causes high demands on quality control. 2D or 3D sensor technology can be used for data acquisition to monitor the weld quality after laser welding. Compared to a 2D camera image, the 3D height data, e.g. acquired using optical coherence tomography, contains additional relevant information for quality inspection. However, the disadvantages are system complexity, higher costs, and longer acquisition times. Therefore, we compare image-based methods with the quality assessment based on height data. The first method uses feature vectors from grayscale images taken coaxially with the laser beam. The significant advantage is that a camera is often integrated into the laser system, so no additional hardware is required. In the second approach, we use an AI-based single-view 3D reconstruction method. The height profile is reconstructed from a camera image and used for further quality assessment. Thus, we combine the advantages of 2D data acquisition with higher accuracy in evaluating 3D data. In addition, we consider the usually low data availability in the industrial environment in the development of algorithms. We use a training data set with 95 samples and a test data set with 858 samples. The work uses the contracting process of copper wires to produce formed coil windings to illustrate the method. We analyze a data set with different defect types and compare the quality assessment using the height data acquired with OCT, the feature vectors from the camera images, and the reconstructed height data.
Optimization and numerical investigation of combined design of blade and endwall on rotor 67
Authors: Li Xin , Meng Tongtong , Zhou Ling , Li Weiwei , Ji Lucheng
Published: May 2023

In this work, a combined design of blade and endwall using the Extended Free Form Deformation technique is proposed and implemented on a transonic compressor rotor (the NASA Rotor 67). The best combined design is explored by numerical investigations and optimization via Kriging surrogate model method. As a result, by only modifying the hub and blade under 15 % span, the peak adiabatic efficiency is increased by 0.4 % and the overall aerodynamic performance for all operating conditions is also improved. An analysis shows that the enlarged dihedral angle between the hub and blade restrains boundary layer intersection and development. Meanwhile, the optimized hub changes the pressure distribution and prevents migration of cross-flow. As a result, the low-energy flow in the corner is accelerated downstream and the separation is limited, leading to an effective improvement in throughflow capability and aerodynamic performance in the corner region.
A comparative study on the local structures of the V4+ and Cu2+ centers in WO3

The local structures and electron paramagnetic resonance (EPR) parameters (the g factors g

i
and the hyperfine structure constants A

i
, with i = x, y, z) of the V4+ and Cu2+ centers in WO3 were theoretically investigated based on the perturbation formulas of the EPR parameters for 3d1 and 3d9 ions under rhombically compressed and elongated octahedra, respectively. In these formulas, the adopted crystal-field parameters (CFPs) are obtained from the superposition model which enables connection of the CFPs and hence the EPR parameters to the rhombic distortion. Based on the calculations, the impurity-ligand distances of the studied [VO6]8− (or [CuO6]10−) cluster are found to suffer the axial compression (or elongation) δz of about 0.098 Å (or 0.132 Å) along the z-axis, and the additional planar bond length variation δr (≈0.052 or 0.047 Å) along x- and y-axis, respectively, due to the Jahn–Teller (JT) effect.
Blake’s Allegory of Tolerance
Authors: Fogarasi György
Published: May 2023

Glimpsing at the critical discourse of recent decades, one may have the impression that something has become increasingly intolerable about tolerance. The growing number of books on the subject, including surveys of the cultural diversity of related notions, seems to suggest that a growing number of doubts surround not only the feasibility of global practices or institutions of toleration but the status of the very concept of tolerance as well. Arguments about the paradox of tolerance, its boundaries, its difficulty, its crisis, or even its dangers, to mention but a few of the multitude of concerns, are often coupled with eff orts to delineate, and thereby to limit, its scope through distinctions between, say, tolerance and forbearance, toleration and tolerance, acceptance and tolerance, recognition and tolerance, hospitality and tolerance, and so forth. As a proponent of the latter divide, Jacques Derrida has argued that, unlike hospitality, the concept of tolerance still seems to imply a notion of power and sovereignty which should be critically superseded and replaced by a disposition that is no longer an “invitation” of the other but an openness to its unexpected and incalculable “visitation” (Derrida, “Autoimmunity” 129). For Derrida, tolerance could still be described as a conditional mode of hospitality, whereas what we would really need is an absolute opening toward alterity or futurity, one which leaves behind any attempt at calculating what is to come, and is in that sense purely unconditional. Such an openness could rightfully be called hospitality per se.

Professor Herbert Woodward Martin and his family arrived in Pécs thirty years ago, in early September 1990. He earned a Fulbright grant to teach American and African American literature courses to students of the English Department of Janus Pannonius University as the institution was called at that time. Martin was not the first Fulbright scholar in the department but the first African American who, among other subjects, familiarized the English majors with poems published in The Poetry of Black America: Anthology of the 20thCentury, edited by Arnold Adoff and introduced by Gwendolyn Brooks. The anthology contains some poems by Martin too, including “A Negro Soldier’s Viet Nam Diary,” which has heart-wrenching lines about a black soldier facing the loss of innocent lives in a land destroyed by modern weapons, where “Death hangs on the rice” (Martin, “A Negro Soldier’s” 228)

Do What You Love? New Music, New Work—After 2020
Authors: Kaneda Miki
Published: May 2023

This article analyzes musical labor and notions of love in relation to gig work with a focus on musicians in new music in New York City. Working in new music as a gig worker entails many skills, many tasks, and many jobs, which hardly guarantee a release from precarity. Meanwhile the neoliberal myth of a “labor of love” propagates the conviction that love and hard work can overcome any challenge, including those posed by racialized and gendered difference. The account of contemporary musical labor I offer concurs with recent critiques of the complicity of new music discourse with neoliberal agendas. Yet I argue that even as contemporary practices of musical work demonstrate how new music is entrepreneurial work embedded in a capitalist system, the everyday experiences of working musicians confound a totalizing account of the neoliberal agenda. Musical work takes place alongside and despite neoliberalism. Based on ethnography and interviews, I argue that the unsettled norms of musical gig work in the first year of the COVID-19 pandemic brought to the fore ways in which musical work is more than the perfect manifestation of exploitable “labors of love.”
The Relationship of Musical Expertise, Working Memory, and Intelligence
Authors: Arndt Christin , Schlemmer Kathrin , van der Meer Elke
Published: May 2023

The connections between musical expertise, working memory (WM), and intelligence have been examined repeatedly in recent years with, to some extent, conflicting evidence. For this reason, more studies are needed that can clarify this matter. The present study investigated connections between musical expertise, WM, and intelligence. Fifty musicians and 50 nonmusicians solved tasks to measure WM (phonological and visuospatial) and intelligence (crystallized and fluid). The results provided further evidence that musical expertise is associated with a superior phonological WM, but not with a superior visuospatial WM or crystallized and fluid intelligence.

Objective: to evaluate the relationship between bio sociodemographic characteristics and advanced activities of daily living in hospitalized elderly people. Methods: cross-sectional study. Two hundred hospitalized elderly people participated. The instruments were used: Mental Status Assessment Questionnaire, Bio-sociodemographic and Health Characterization Instrument and Advanced Activities of Daily Living Scale. Results: age impacted social (p=0.024), leisure (p=0.004), intellectual (p=0.017) and religious (p=0.047) activities. Regarding gender, men presented higher scores in leisure (p=0.046) and intellectual (p=0.002) activities; on the other hand, women obtained better scores in religious activities (p=0.001). The variables "family income", "physical disability" and "physical activity" were significantly associated with the global score. Conclusion: there was an association of the variables "age", "education", "family income", "physical disability", "physical activity practice" and "health status perception" with the global score of the scale. Most of the bio sociodemographic variables showed association with the Leisure Activities domain. Contributions to practice: the elucidation of factors that may be related to the performance of advanced activities in hospitalized elderly people can support the improvement of care.
Stasis, saturación cultural, pérdida de presencia
Authors: Díaz Soto David
Published: May 2023

Planteamos una comparación entre dos autores, el filósofo y teórico del cine Stanley Cavell y el musicólogo y filósofo Leonard B. Meyer, que desde perspectivas análogas reflexionan sobre transformaciones en la cultura reciente, particularmente, la atomización y saturación del espacio cultural, debida a la actividad de producción y clasificación operada sobre el mismo, así como la degradación de las relaciones interpersonales, y que las vinculan a una pérdida de intensidad de la relación de la civilización occidental con el presente, arrinconado por un pasado inmediato cada vez más denso y por un futuro inmediato cada vez más adireccional. Ello se mostraría en la reciente producción artística y cultural. Las diferencias entre ambos autores muestran la distancia entre el esteta “integrado” (Meyer) y el moralista “apocalíptico” (Cavell).

Con las Edades del Mundo de 1811 Schelling comienza la reelaboración de su filosofía y se distancia del pensamiento de la época que precede dicho escrito. El rechazo a una deducción lógica de los principios de la filosofía para dar paso a la inserción de principios móviles constituirá el inicio de una nueva manera de entender la filosofía, ya no como una construcción racional a partir de principios, sino como narración del despliegue de tales principios en la historia.

Anticipated shame and professional identity formation
Authors: Lusk Penelope
Published: May 2023

Developing a professional identity in physicians-in-training is a central, but contested, outcome of medical education. In recent years scholars have argued for the importance of including affective experiences, especially shame, in the discourse around medical training. This discourse reflects projection and anticipation around both shame and professional identity, and the question of how shame impacts the latter is critical. Shame is an affect that arises when the self is confronted by the gaze, judgment or awareness of an Other; it can have profound impacts on identity and self-concept, and is highly prevalent in medicine and healthcare. This article posits ‘anticipated shame’ as a potent factor implicit in the experience of developing a medical professional identity, and connects shame to stigma and marginalization in medical training. Shame, and the anticipation of shame in student–teacher and trainee–patient interactions, highlights aspects of interpersonal communication within medical training and then practice. The concept of anticipated shame offers rich ground to theorize the effects of affect in medical education, and how trainees internalize medical cultural values and then enter the field of clinical practice.
Another’s voice

Published: May 2023

This study examines the interactional functions of an evidential marker -tay in the Korean language. Despite the frequent use of -tay in everyday interactions, the role of this marker in spoken communication has not been sufficiently explored, compared to other Korean quotative expressions. By analysing telephone conversations, this study shows that -tay conveys not only another’s utterances but also indicates interaction-oriented functions in various contexts: as a marker of presenting evidence, detailing context in telling a story and introducing a new topic. In addition, this paper will discuss how speakers use this marker to facilitate interaction with hearers by incorporating multiple voices into spoken discourse and creating new meanings, including the “voice” of a third party and also speakers’ own “metamessages”.
Gendering desire
Authors: Kroo Judit
Published: May 2023

This study considers the use of the multivalent casual Korean lexical item ya in a Korean television drama. Meanings of ya include “hey” and “oh!” and ya can convey a variety of affective connotations ranging from anger to romantic teasing depending on context and intonational contours. Exploring patterns of use of ya, this study highlights how the differences in intonational contour and choice of addressee are linked to valences of “forcefulness” and “failed forcefulness” that are implicated in the construction and performance of diverse youth-associated gendered styles. It argues that heteronormatively desirable masculine and feminine styles are constructed through the strategic use and non-use of ya. Specifically, romantically desirable femininity relies on the performance of failed forcefulness that creates opportunities for masculine-marked performances of paternal care.
When two cultures meet

The present study investigated the use of strategies by Chinese learners of English and English learners of Chinese in making requests in both Chinese and English. Three factors affecting request strategies were also examined, including social power, social distance and degree of imposition. A total of 12 Chinese-speaking and 12 English-speaking students were recruited to complete Chinese and English versions of an oral discourse completion task (ODCT). Request behaviour was examined in both the subjects’ native and non-native languages. The results show that the learner and native speaker groups performed differently in making Chinese requests but employed comparable strategies in making English requests. Moreover, social distance was found to be more influential than social power and degree of imposition in making Chinese requests. However, the influence of these factors was similar in making English requests. The findings suggest that it was easier for the learners of Chinese to master English requests than for the learners of English to acquire Chinese requests.

ANTIBIOTIC SENSITIVITY OF LACTOBACILLI ISOLATED FROM DIFFERENT SOURCES IN THE ODESA REGION
Authors: Yamborko G. , Strashnova І.
Published: May 2023

Recently, possible co-application of probiotics and antibiotics has been widely discussed. This form of combined therapy, because of its commonly recognised advantage, is widely used to prevent antibiotic-associated diarrhoea and induced dysbiosis. Due to the increased application of lactobacilli as probiotics, EFSA has developed a number of requirements concerning their safety and functionality. Every commercial probiotic should be able to obtain the Qualified Presumption of Safety status (QPS). Though QPS is a status attributed to species, individual species differ greatly in their genome content, including those belonging to the genus Lactobacillus. Infectious bacteria and strains that may possess genes responsible for virulence or antibiotic resistance should not be used lest pathogenic genes be passed on to other species. The human gastrointestinal tract, due to the immense amount of bacteria and the close contact between them, is a possible place for gene transfer. The main hazard is the transfer of antibiotic resistance determinants from commensal bacteria and the emergence of resistance to common microbial infections, which can prevent successful antibiotic treatment. A condition of using bacterial strains as probiotics is their safety, in particular, the absence of antibiotic resistance determinants. The purpose of the work was to determine the antibiotic sensitivity/resistance of lactobacilli isolated from different sources in the Odesa region. By the disc diffusion method, it has been determined how sensitive the 13 lactobacilli strains isolated from auto-fermented vegetables, raw meat, and newborn children’s gastrointestinal tract are to 15 antibiotics with different mechanisms of action. It has been established that the sensitivity/resistance depended on the strain and specific antibiotic. An obvious feature of the strains under study was their higher sensitivity to antibiotics that inhibited the synthesis of protein and nucleic acids, as opposed to antibiotics that affected the synthesis of the cell wall and cytoplasmic membrane. The results of the comprehensive research have allowed selecting the Lactobacillus spp. strains O1, B4, 175, M2, and M3 as the most promising for the creation of probiotic preparations.
EVALUATION OF THE DEGREE OF SNAIL MEAT FRESHNESS BY THE PHOTOMETRIC METHOD
Authors: Danilova I. , Danilova T.
Published: May 2023

This work focuses on developing a method of determining the degree of freshness of snail meat by means of a photoelectric photometer. For this, the absorbance was measured in filtered meat-water extract with Nessler’s reagent added. The method can be used in laboratories to determine the quality of meat of snails during their processing and sale. The results of using this method allow obtaining quantitative values when assessing the quality of snails of different degrees of freshness. A selection of 180 Helix pomatia snails was studied. They were divided into three groups, 60 snails in each, in accordance with the meat freshness degree. Three degrees of meat freshness were distinguished: fresh, questionably fresh, and stale. Meat samples were taken from all the snails of each group. Then the meat was ground, and 2.00 g portions were taken from each sample. 20.00, 30.00, 40.00, and 50.00 cm3 of distilled water were added successively to the weighed portions. They were infused for 15 minutes and then filtered. 0.50 cm3 of Nessler’s reagent was added to 3.00 см3 of the filtrate. The absorbance of the colour intensity of the meat-water extracts was measured with a concentration photocolourimeter extended in the range of light waves from 400 nm to 490 nm. It has been established that the highest absorbance indicates stale meat, the lowest is characteristic of fresh meat, and the value of absorbance for questionably fresh meat lies in between. Thus, when the concentration of snail meat extract was 1:10, at the wavelength 440 nm, the absorbance values were 1.243±0.031 for stale meat, 0.262±0.034 for fresh meat, and 0.804±0.054 for questionably fresh meat. This may be due to an increase in the ammonia concentration during the meat spoilage process. The three degrees of meat freshness were best determined at the wavelengths 440 nm and 490 nm. The results obtained are qualitatively and quantitatively in line with those of photometric studies of the freshness degree in beef, poultry, and fish.

The increased consumption of edible mushrooms is not only due to their nutritional value, but also to their unique taste and specific flavor. The aroma of cultivated mushrooms is different from wild ones, it is often less pronounced. The aim of the study was to determine the characteristics of the aroma of wild and cultivated edible mushrooms using the methods of sensory profile analysis and ultraviolet spectrophotometry. Sensory profile analysis showed that aroma profiles of mushroom samples differed in intensity depending on a kind of a mushroom. It was found that Boletus sp. had the highest intensity of the mushroom component of flavor among wild mushrooms. The intensity of woody flavor components was higher in B. subtomentosus, L. aurantiacum and P. ostreatus IBK-1535. More pronounced herbaceous notes were observed for a wild P. ostreatus and A. silvaticus, sweet – for S. luteus, and floral – for P. djamor. Among the cultivated fungi, the most pronounced mushroom notes are observed for A. bisporus. The lowest intensity of aroma had such wild mushrooms as P. ostreatus and S. luteus. Also, the least pronounced flavor was noted for the cultivated P. djamor. The flavor of this mushroom is characterized by fishy notes. The obtained UV-spectra of different mushroom species varied in the intensity of the light absorption maxima. The highest intensity in the entire wavelength range had the extract of B. edulis fruit bodies. Among the cultivated fungi, A. bisporus was characterized by the highest optical density of hexane extract at 207 nm, and A. bisporus and P. ostreatus strains IBK-551 and IBK-1535 absorbed light the most intense in the region of 260–290 nm. The results of determining the organoleptic profile and spectrophotometric analysis of mushroom extracts indicate that the industrial cultivation of edible mushrooms disrupts or inhibits the formation of aroma substances by fruiting bodies, which leads to a decrease in their consumer quality. Therefore, in order to increase the demand for cultivated edible mushrooms, the flavor of which is one of the determining factors of their attractiveness, it is necessary to conduct a comprehensive study of the dependence of the aroma substances formation on the growing process parameters.

Today, more and more food manufacturers are abandoning the usage of synthetic antioxidants because of the negative impact they have on the human body. The main natural hydrophobic antioxidants such as tocopherols and carotenoids, are not cheap commercial products and are currently produced much less than fat industry requires. Therefore, obtaining other natural antioxidants from vegetable raw materials could be a solution. Among the potential sources of such raw materials were leaves and roots of herbs, bark and leaves of berry crops. 20 plants were studied. The purpose of the study was to obtain comparative data on the antioxidant activity of water-alcohol extracts of Ukrainian origin plants, as well as to study their influence on the stability of sunflower oil during its heat treatment. The induction periods of sunflower oil in the presence of antioxidants were determined, the antioxidant activity of plant extracts was determined based on the data obtained and compared with the antioxidant activity of synthetic butylhydroxyanisole, antioxidants were used in equal concentrations (200 ppm). The obtained plant extracts are arranged according to their antioxidant activity in a series (in order of decreasing activity): lemon balm grass > spirea grass > burdock root > bark of European guelder > blackberry leaves > blueberry shoots > thyme grass > raspberry leaves > calendula flowers > oak bark > mountain ash > leaves nettles > mountain ash > rosemary leaves > echinacea flowers > parsley > arugula > peppermint leaves > chamomile > dill. All deep-frying fats need protection from oxidative damage, especially unsaturated fats such as sunflower oil, which is currently widely used in deep-frying in the restaurant segment. From the results of the study, it can be concluded that the natural antioxidant (water-alcohol extract of bark of European guelder) was more effective than the synthetic antioxidant butylhydroxyanisole in inhibiting oxidative and hydrolytic processes during heat treatment of sunflower oil. During 5 days of heat treatment, the sample of sunflower oil with bark of European guelder extract was characterized by the lowest values of acid, peroxide and anisidine numbers.

This paper discusses the book Poor, disabled and homeless people in the social welfare system by M. Małecka-Łyszczek and R. Mędrzycki. The Authors rightly point out that the division they adopted in the title cannot be isolated because poverty, disability and homelessness, are overlapping factors, deepening and perpetuating the social exclusion of individuals and families affected.

Aim. To develop predictive models of inhospital mortality (IHM) in patients with coronary artery disease after coronary artery bypass grafting (CABG), taking into account the results of phenotyping of preoperative risk factors.

Material and methods. This retrospective study was conducted based on the data of 999 electronic health records of patients (805 men, 194 women) aged 35 to 81 years with a median (Me) of 63 years who underwent on-pump elective isolated CABG. Two groups of patients were distinguished, the first of which was represented by 63 (6,3%) patients who died in the hospital during the first 30 days after CABG, the second — 936 (93,7%) with a favorable outcome. Preoperative clinical and functional status was assessed using 102 factors. Chi-squares, Fisher, Mann-Whitney methods were used for data processing and analysis. Threshold values of predictors were determined by methods, including maximizing the ratio of true positive IHM cases to false positive ones. Multivariate logistic regression (MLR) was used to develop predictive models. Model accuracy was assessed using 3 following metrics: area under the ROC curve (AUC), sensitivity (Sens), and specificity (Spec).

Results. An analysis of preoperative status of patients made it possible to identify 28 risk factors for IHM, combined into 7 phenotypes. The latter formed the feature space of IHM prognostic model, in which each feature demonstrates the patient’s compliance with a certain risk factor phenotype. The author’s MLR model had high quality metrics (AUC-0,91; Sen-0,9 and Spec-0,85).

Conclusion. The developed data processing and analysis algorithm ensured high quality of preoperative risk factors identification and IHM prediction after CABG. Prospects for further research on this issue are related to the improvement of explainable artificial intelligence technologies, which allow developing infor­mation systems for managing clinical practice risks.

Aim. Identification and analysis of the features of vascular stiffness, 24-hour blood pressure (BP) profile, and central aortic pressure (CAP) in patients with hyper­tension (HTN) and anxiety-depressive disorders (ADDs) during andro- and meno­pausal periods.

Material and methods. The study included 120 patients with uncontrolled hyper­tension in the andro- and menopausal periods, of which 60 patients with hyper­tension and ADDs (30 men and 30 women) with median age of 58 years (52-64 years), as well as the control group — 60 patients with hypertension without ADD (30 men and 30 women) with median age of 59 years (53-65 years). All persons included in the study underwent 24-hour ambulatory BP monitoring (ABPM) and assessed the arterial stiffness parameters and CAP.

Results. Comparative evaluation of ABPM in the group of patients with HTN and ADDs revealed more pronounced pathological changes in the 24-hour BP profile compared to those in the control group. Andro- and menopause with a combination of HTN and ADDs characterized by significantly higher ABPM parameters than HTN without ADDs (regardless of the sex). At the same time, in the group of men with HTN and ADD in andropause, unfavorable changes in the main arterial stiffness parameters and CAP were more significant than in women with HTN and ADD during menopause (p<0,05). In the control men groups, in comparison with women, more pronounced unfa­vo­-rable changes in certain vascular stiffness indicators, CAP and ABPM were recorded.

Conclusion. In men and women in periods of andro- and menopause with HTN and ADDs, the features of arterial stiffness, CAP, and 24-hour blood pressure profile were verified in comparison with patients with HTN without ADDs. At the same time, the severity of unfavorable changes in the studied parameters in men with depression in andropause is more significant than in menopausal women.
