TUDOMÁNY ÉS MŰVÉSZET EGYÜTTES JELENLÉTE PUKÁNSZKY BÉLA PROFESSZOR ÉLETPÁLYÁJÁN
Authors: Molnár-Tamus Viktória
Published: December 2021

A debreceni egyetem bölcsészettudományi kara történetének első korszakában több oktató is szoros kapcsolatban állt a művészetekkel. Ez a tanulmány elsősorban a pozsonyi kötődésű Pukánszky Béla professzor zenei jelentőségét kívánja bemutatni. A kutatás során próbáltam a személyes hagyatékok fennmaradt iratait, illetve a kortárs tudóstársak, kollégák által írt kritikákat, recenziókat és jubileumi tanulmányokat elolvasni és feldolgozni. Pukánszky Béla esetében a Debreceni Egyetem Kézirattárában fennmaradt dokumentumokra (jegyzőkönyvek, hangverseny-meghívók, kézírásos és gépelt szövegű zenetörténeti előadások), azon belül is elsősorban felesége levelezésére támaszkodtam. Ezek eredményeként beszámolok Pukánszky Béla művészetekkel foglalkozó tudományos és ismeretterjesztő írói, illetve előadói tevékenységéről, hogy milyen aktív szerepet vállalt Debrecen és Budapest, tulajdonképpen egész Magyarország művészeti közéletében. Kutatásom eredménye így a debreceni egyetemi bölcsészkar, valamint a város országos szinten is kiemelkedő értelmiségi köreinek jelentős művelődéstörténeti, kulturális ismeretterjesztési és művészetpártolói ténykedésének eddigi eredményeit gazdagítja.
EGYETEMJÁRÁS KUTATÁSA EURÓPÁBAN
Authors: Szögi László
Published: December 2021

A külföldi egyetemjárás, a peregináció történetének kutatása Európa valamennyi nemzete számára fontos téma. Az európai centrum, azon országai, ahová irányult a peremvidékekről az egyetemjárás, elsősorban befogadó egyetemekkel rendelkeztek, és számukra fontos saját kapcsolataik és vonzáskörzetük vizsgálata. Ez elsősorban az itáliai, francia és német egyetemek esetében jellemző. Ugyanakkor ők is vizsgálják saját egyetemjárásukat a centrum más régióival kapcsolatosan. Az Európa északi, keleti és déli végein található országok egy részének viszonylag korán alakultak saját egyetemei, de mégis nagy számban küldtek diákokat a centrum országok egyetemeire, így ennek kutatása számukra is fontos. Például a spanyol és portugál történetírás számára fontos kérdés a francia és itáliai egyetemjárás vizsgálata. Skandinávia és Közép-Európa régebbi államaiban ugyan viszonylag korán létrejött egy-egy univerzitás, de ezek működése nem volt állandó, így e nemzetek értelmiségének döntő többsége külföldi egyetemeken nevelkedett. A 19-20. században függetlenné vált kisebb európai államokra mindez fokozottan igaz, így számukra még inkább fontos nemzeti értelmiségük kialakulásának vizsgálata. A tanulmány e kérdéseket tárgyalja bemutatva az e témakörben végzett kutatásokat.

A tanulmány Filiczki János album amicorumának meglepően kevés magyar vonatkozású bejegyzésével foglalkozik. Ezeket európai peregrinációja során, 1600 és 1616 között írta be Adam Kunisch, Johann Frölich, ifj. Sebastian Ambrosius, Miskolci Csulyak István, Joannes Bocatius, Szenci Molnár Albert, Johannes Blofus, Maximilianus Fabinus, Debreceni Dormány István, Keserűi Dajka János, Váradi Farkas Gergely, ifj. Gregor Tribel és végül Elias Berger. Az általában sablonos bejegyzések némelyikét közelebbről is megvizsgálva, új információk és értékes adalékok nyerhetők a bejegyzők tanulmányaival, életével kapcsolatban. Ebből a szempontból épp azok az ismeretlenség homályában ragadt figurák lehetnek különösen érdekesek, akik a korabeli értelmiségi réteg feltörekvő, fiatal képviselői voltak. Közülük is ifj. Sebastian Ambrosius, Maximilianus Fabinus és ifj. Gregor Tribel bejegyzései tűnnek a leginkább figyelemreméltónak. A bejegyzések elemzésén túl, a latin szövegek fordítását is igyekeztem közölni
ADLER PÉTER SZTOMATOLÓGUS PROFESSZOR ELFELEJTETT HÁBORÚS VISSZAEMLÉKEZÉSE
Authors: Kelentey Barna
Published: December 2021

2021 nyarán -váratlanul- Adler Péter professzor könyvhagyatékához jutottunk. Adler professzor 1946-1978 között vezette a debreceni Stomatológiai Klinikát, és nemzetközileg elismert szaktekintély volt. A hagyaték részeként kaptunk egy amerikai fogászati folyóiratot is, melynek 1947-es száma tartalmazott egy névtelenül közölt cikket, mely egy magyar fogorvos II. világháborús kálváriájáról számol be. Az adatokból és a leírásokból egyértelműen kiderül, hogy Adler Péter professzor írta a közleményt. Érdekes olvasmány, mely természetesen kissé szubjektív megközelítésű és figyelembe kell venni, hogy külföldieknek, elsősorban amerikaiaknak íródott. Különlegessége, hogy magyarul eddig -tudtommal- sehol sem jelent meg. Akkori közlése a hidegháború kezdetére datálható, mely esetleg magyarázatot ad arra, hogy miért kérte a szerző az anonimitást. A cikk olyan fontos hiánypótló információkat tartalmaz, melyek révén hozzájárulhat a korszak jobb megismeréséhez.

A house of worship is a place where religious people meet for the teachings of their respective religions or beliefs. Knowing the information on the location of places of worship is very important to fulfill worship obligations. In the city of Mataram, finding places of worship is still quite difficult because they cannot walk / walk around them. In terms of the Ministry of Trade, there is still no data management system for places of worship, currently data management for places of worship is still carried out using Ms. Excel which makes data collection ineffective and takes a long time to search for existing data, information media and mapping. there are no places of worship in the city of Mataram either. In this Final Project research, a Geographical Information System for Mapping the Location of Places of Worship in the City of Mataram was designed and built to provide information and layouts regarding places of worship in the city of Mataram because when searching for places of worship meant a more important geographical location was needed. With this system that has been created, it can provide benefits for the general public in viewing information and locations of places of worship in Mataram City, as evidenced by the results of the questionnaire given which can be seen in Table 4.25 showing that 40.33% strongly agree, 47.85 % agree, and 11.83% quite agree. And from the side of the Ministry of Trade it can also make it easier to collect data from systems that make management more effective and efficient, it can be proven through the results of the questionnaire in Table 4:24 showing that 66.67% strongly agree, 25% agree, and 8.33% are quite related with easy access to the application, the display is easy to understand, the application runs well, helping the Ministry of Religion in the organization of existing places of worship data. In this final project research uses the Extreme Programming method in the system development process, because it is suitable because one of the XP itself involves the client during the system development process, while in the case of this Final Project research, the Ministry of Religion of NTB as a client is directly involved in the system development process so that Minimizing errors in the system and in accordance with client needs, it can be proven in the results of the black box testing that has been carried out in Table 4:23 showing that all functions work well on the system and are accepted so that it can be said that the system created is running according to client needs.

Published: December 2021

At HOTSPODT (Hospital Ship for Covid Disaster) there are no stages regarding the application of the use of information technology systems, especially for securing patient data which includes personal data and patient medical records. Confidential patient data collected during the current pandemic, including the patient’s name, address, diagnosis, family history and medical records without the patient’s consent, may pose a risk to the individual concerned. The concept of patient data security is adjusted to the user’s position on the importance of data. Access to patient data authorization is one of the security gaps that the security system needs to pay attention to and guard against. So, in this case applied a data security algorithm in the form of cryptography. The algorithm used is the Blowfish Algorithm. The test results of the scenario in the application prove that it can be successfully processed from the encrypted file to ciphertext until it is returned as the original file.

Features of vascular-platelet and coagulation hemostasis in relation to parameters of macular blood fl ow in women with preeclampsia
Authors: Kolenko O. V. , Sorokin E. L. , Fil A. A.
Published: December 2021

Background. Recently, more and more attention has been paid to the development of vascular retinal disorders after suffering preeclampsia. It is noted that the key role in this process is assigned to the systemic endothelial dysfunction that persists for a long time after delivery.Aim: to elucidate the features of vascular-platelet and coagulation hemostasis in relation to the indicators of blood flow in the macular region in women with preeclampsia.Materials and methods. The main group included 45 women with preeclampsia in the third trimester of pregnancy (35–36 weeks). Their age ranged from 19 to 40 years (27 ± 5.2 years). The comparison group was represented by 20 women with physiological pregnancy in the third trimester (35–36 weeks). Their age averaged 26 ± 5.1 years (18–38 years). Somatically healthy non-pregnant women (20 people) were included in the control group. Their age ranged from 19 to 38 years (26 ± 5.4 years). A comparative analysis of the studied parameters of macular blood fl ow, vascular-platelet and coagulation hemostasis between the groups was carried out.Results. When studying the number of platelets in pregnant women, it turned out that in patients with preeclampsia, this indicator was statistically signifi cantly lower compared to the comparison and control groups (p < 0.05). The level of fi brinogen in women with complicated pregnancies was statistically significantly higher than in women with physiological pregnancy and in somatically healthy nonpregnant women (p < 0.05). In addition, retinal microcirculation disorders were observed in women of the main group.Conclusions. The revealed disorders of vascular-platelet and coagulation hemostasis in women during the period of complicated pregnancy were accompanied by disorders of macular blood fl ow in the form of a decrease in the total average density of vessels in the superfi cial vascular plexus, subfoveolar thickness of the choroid and an increase in the area of the avascular zone relative to the group of women with physiological pregnancy and somatically healthy nonpregnant women.
Assessment of the degree of restoration of the retinal structure and chorioretinal blood flow after surgical treatment of large-diameter macular holes
Authors: Bronskiy D. I. , Zhukova S. I. , Zaika V. A. , Shchuko A. G.
Published: December 2021

The aim: to evaluate the restoration features of the structural relationships of the retina and chorioretinal blood fl ow after surgical treatment of large-diameter macular hole (MH) using a modifi ed technology.Material and methods. A prospective study of 14 patients (14 eyes), 13 women and 1 man, with medium-and large-diameter MH was conducted. The mean age of the patients was 67.7 ± 5.38 (55–80) years. The study included patients with endto-end MH of the 3rd–4th stage according to the classifi cation of J. Gass. All patients underwent surgical treatment of macular rupture according to the proposed method of inverted fl ap of the internal limiting membrane (ILM) and fi lling it into a “pocket” formed between the retina and the ILM.Optical coherence tomography (OCT) was performed along with traditional research methods. The obtained images were used to measure manually the parameters of retinal MH, the thickness of the choroid in the projection of the rupture and the fovea zone before the operation and 1, 3 and 6 months after the operation. In the angio-mode, the foveal avascular zone (FAZ) was evaluated, as well as the density of capillaries of the superfi cial and deep retinal plexus in four quadrants, with the exception of the central zone.Results. In all patients, it was possible to achieve MH blocking. Visual acuity in the eyes with MH varied from 0.02 to 0.3, while in the comparison group, the best corrected visual acuity was from 0.3 to 1.0 (p = 0.002). An increase in the diameter of large choroidal vessels, as well as a pronounced decrease in the diameter of the posterior short ciliary artery, attracted attention. However, despite the improvement in visual acuity, patients retained a signifi cant expansion of the FAZ, which by 6 months exceeded the FAZ area of the paired eye by 25.8 % (p = 0.01).Conclusion. The results obtained indicate that the achievement of an anatomicalreconstructive effect and even a moderate improvement in visual acuity during surgical treatment of macular holes by the modifi ed inverted flap technology of the internal limiting membrane does not determine the restoration of retinal perfusion in full.

Brachytherapy in organ-preserving treatment of choroidal melanoma: complications and the possibility of their prediction
Authors: Bykhovsky A. A. , Panova I. E. , Samkovich E. V.
Published: December 2021

This review analyzed the domestic and foreign literature on brachytherapy of choroidal melanoma using ruthenium ophthalmic applicators. The review highlights the historical aspects of radiation treatment, from the first experience of using ionizing radiation in the treatment of malignant neoplasms to modern methods of brachytherapy; presents the radiobiological foundations of radiation therapy; considers the issues of radiation pathomorphosis, reflecting the nature of pathological changes in the choroidal melanoma tissue during brachytherapy; shows the dependence of the effect of exposure ionizing radiation from the phase of the cycle of cell division; and also describes the presence of changes characteristic of the response to ionizing radiation in unirradiated tissues. The analysis of various post-radiation complications, both early and late, was carried out in some detail, with emphasis on the possibility of predicting and preventing them in real clinical practice. A comparison is made in terms of the frequency of development of various post-radiation complications in the works of domestic and foreign authors, as well as a comparison with the effect of ionizing radiation from other radioactive isotopes. Recommendations of experts are given regarding the correct calculation of the dose to the sclera and medication support, based on many years of experience in the use of ruthenium ophthalmic applicators for brachytherapy of choroidal melanoma. The risks of developing such late complications as radiation maculopathy and radiation neuropathy have been demonstrated, especially in pre-equatorial tumor localization. The possibilities of modern methods of instrumental diagnostics for studying the processes occurring in the area of the tumor, as well as changes in the surrounding tissues, are shown, which determines the feasibility and importance of further study of this issue.
Surgical treatment of the humeral head osteochondral defects in chronic shoulder dislocation: Literature review
Authors: Monastyrev V. V. , Chimytov B. A.
Published: December 2021

Background. The shoulder joint is the one most amenable to dislocation. Dislocation of the humeral head is complicated by combined injuries of the shoulder joint, and if the patient does not seek treatment on the first day after the dislocation, irreversible changes in bone and soft tissue structures are formed.The aim of this review was to analyze modern methods of diagnosis and treatment of patients with defects in the articular surfaces of the scapula and humerus head with chronic shoulder dislocations.Material and methods. To search for literature data, we used the electronic databases MEDLINE, PudMed, eLIBRARY with a selection of sources published from 2000 to 2020. The analysis was carried out on works devoted to the diagnosis, surgical treatment and complications of traumatic shoulder dislocations.Results. When analyzing the literature on the surgical treatment of shoulder dislocations, we did not find clear criteria for planning the extent of surgery. The obtained results of surgical treatment testify to well-studied technologies for treating osteochondral defects of the humeral head up to 25 % of its total area. In the presence of a defect of 50 % of humeral head area or more, satisfactory results are shown when carrying out arthroplasty of the joint using a reverse endoprosthesis. However, the treatment of defects ranging in size from 25 to 50 % is still an unexplored problem. There are single techniques using allografts, mainly in English-speaking countries and, to a lesser extent, on the territory of the Russian Federation. Thus, the search for an algorithm for choosing a surgical treatment based on multi-layer spiral computed tomography and/or magnetic resonance imaging data, and the development of a new method of surgical treatment taking into account the obtained data are priority areas in modern traumatology and orthopedics.
The role of pharmacogenetics in Efficacy and safety of protease inhibitor based therapy in human immunodeficiency virus type (HIV) infection.

Published: December 2021

Antiretroviral therapy has markedly reduced morbidity and mortality for persons living with human immunodeficiency virus (HIV). HIV can now be classified as a chronic disease; until a cure is found, patients are likely to require life-long therapy. However, despite these undoubted advances, there are many issues that need to be resolved, including the problems associated with long-term efficacy and toxicity. Moreover, pharmacotherapy of patients infected with HIV is challenging because a great number of comorbidities increase polypharmacy and the risk for drug-drug interactions. There is considerable interindividual variability in patient outcomes in terms of drug disposition, drug efficacy and adverse events. The basis of these differences is multifactorial, but host genetics are believed to play a significant part. HIV-infected population consists of ethnically diverse individuals on complex and potentially toxic antiretroviral regimens on a long-term basis. These individuals would benefit greatly from predictive tests that identify the most durable regimens. Pharmacogenetics holds that promise. Thus, detailed understanding of the metabolism and transport of antiretrovirals and the influence of genetics on these pathways is important. To this end, this review provides an up-to-date overview of the metabolism of antiHIV therapeutics of the protease inhibitors Lopinavir and Ritonavir and the impact of genetic variation in drug metabolism and transport on the treatment of HIV.
Prospects for prevention of adhesion process during cardiac surgical interventions
Authors: Shurygin M. G. , Shurygina I. A.
Published: December 2021

The article is devoted to the problem of prevention of adhesions in cardiac surgery. It was determined that the problem is urgent due to the increase in the number of heart surgeries. The formation of adhesions is a reaction of the body after surgery, which is a stage of healing and partly performs a protective function. Nevertheless, the presence of adhesions violates the mechanical properties of the heart, negatively affects central hemodynamics, complicates the surgeon’s task during repeated surgical interventions and increases the risk of repeated operations.It has been shown that at present, for the prevention of adhesions, researchers tend to use biodegradable barrier materials with biocompatibility and the ability to dissolve after performing the barrier function. The main anti-adhesion agents used in cardiac surgery are membranes and gels. The requirements for an “ideal” agent for the prevention of adhesion were determined: biocompatibility, no irritating effect, no effect on wound healing, suppression of the growth of connective tissue in the pericardium.Conclusions. Until now, none of the funds has all the necessary qualities to prevent adhesion in the pericardium. Therefore, the search for effective methods for the prevention of postoperative adhesions remains relevant for cardiac surgery.

Background. The COVID-19 pandemic has raised the importance of this problem to the first stage and has affected healthcare system around the world. Despite the more favorable COVID-19 course, the child population should be at focus of special attention, due to the active participation in its distribution. The course of COVID-19 includes a cascade of pathological processes accompanied by the generation of reactive oxygen species, which can have extremely negative consequences for the developing organism. The research of these processes in children is vital and will improve the effectiveness of preventive and therapeutic measures. The aim: to analyze changes in enzymatic and non-enzymatic links in the antioxidant defense in children and adolescents with diagnosed COVID-19 infection.Materials and methods. 17 children and adolescents (average age – 12.35 ± 4.01 years) were examined, including 8 boys (47 %) and 9 girls (53 %) with COVID-19 infection. The control group of children and adolescents (practically healthy) according to the «copy-pair» principle was selected. We used spectrophotometric methods.Results. In the group of children and adolescents with diagnosed COVID-19 infection, there were lower levels of total antioxidant activity (p < 0.0001), superoxide dismutase activity (p < 0.0001), content of reduced glutathione (p = 0.048) and retinol (p = 0.015), increase in glutathione reductase activity (p = 0.015) relative to the control.Conclusion. The obtained data indicate the insufficiency of antioxidant system components number in children and adolescents with diagnosed COVID-19 infection and indicate the advisability of antioxidant therapy using to stabilize these indicators.

The simultaneous arrangement of home and work life is important for all. Many who work at home, however, face difficulties in maintaining their work and domestic relations balance, since both fields are mixed together on a single roof. As telecoms technology progresses, the possibilities of working from home have been improved. Discussed the effects of working at-home solutions on the quality of work life of the individual. The current research examined in a sample of service workers from Pakistan an extended version of the differential salience model and a related salience model. The findings of this study help in part the model in a number of cultural and domestic contexts, but they also establish variations in domain resources and limit requirements. Strong job demands and the present situation of COVID-19 represent primarily technically the work-to-home interference (WtHI). Traveling tools have been identical in terms of reducing the WtHI and work-to-home enhancement (WtHE). WtHE was expected to be more likely because of the activation of personnel services. However, testing one's work had no big influence on WtHE. Moreover, unlike the theoretical model, restriction requirements at the interfaces between work and family have been found to be differential, not comparatively significant.

Published: December 2021

In this study, the MHD effect on boundary layer rotating flow of a nanofluid is investigated for the multiple branches case. The main focus of current research is to examine flow characteristics on a nonlinear permeable shrinking sheet. Moreover, the governing partial differential equations (PDEs) of the problem considered are reduced into coupled nonlinear ordinary differential equations (ODEs) with the appropriate similarity transformation.  Numerical results based on the plotted graphs are gotten by solving ODEs with help of the three-stage Labatto IIIA method in bvp4c solver in MATLAB. To confirm numerical outcomes, current results are compared with previously available outcomes and found in good agreement. Skin friction coefficients, Nusselt and Sherwood numbers, velocity profiles, temperature profiles, and concentration profiles are examined. The results show that dual (no) branches exist in certain ranges of the suction parameter i.e., SSc (SSc). Further, profiles of velocity decrease for rising values of Hartmann number in the upper branch, while reverse trend has been noticed in a lower branch. Profiles of temperature and concentration enhance for the increasing values of thermophoresis in both branches. stability analysis of the branches is also done and noticed that upper branch is a stable branch from both branches. Finally, it is noted that the stable branch has symmetrical behavior with regard to the parameter of rotation.

It is widely assumed among academicians that the COVID-19 pandemic has negative implications for the education of school students. However, institutions tried to balance that limitation by using online education, and there exist some inequalities among students. Most of the studies conducted during COVID-19 on online education focused on urban school students and their access to online education. In particular, rural school students and their online education remain an open question. Twenty in-depth interviews with rural student respondents determine the fundamental problems and challenge the rural school students’ face in online education during the COVID-19 pandemic lockdown. The study identifies six major problems of rural students: inadequate technology, unacquainted academic atmosphere, digital disconnect, physical well-being, the distractions inherent with the medium, and digital illiteracy. The identified constraints draw inferences to a critical concept in online learning that is digital inequality. Digital inequality refers to the disparity in the access, distribution of technology, information because of various socio-economic and cultural factors. The study also discusses the suggestions of rural students regarding the betterment of online education. The recommendations from the rural students include providing appropriate technological infrastructure, facilitating technical assistance and providing a convenient academic atmosphere. The suggestions are pointing towards the idea of digital inclusion that is vital in online education. Digital inclusion is defined as the ability of individuals or groups of people to access and use information and communication technologies. It is not only about access in a broader sense the opportunities of using innovative hardware and software technology, content and services, getting proper digital literacy pieces of training and the effective use of these services. The findings of the study will help to bridge the disparities in online education. These findings will help the academic community to identify the needs of rural children. It will help build infrastructure for online learning and give extensive support to the school children of rural communities. These findings are also vital for the communication scholars as the disparity in the distribution of information and knowledge is a prime concern for them.
From “Power of the Worthy” to “Power of the Popular”: Splendors and Miseries of Meritocracy in a New Technological Era
Authors: Davydov D. A.
Published: December 2021

The article is devoted to the study of the phenomenon of meri tocracy, which arouses considerable interest today both in political journalism and academia. The article shows that meritocracy has largely become the ideo logy of modern neoliberal elites, and therefore often serves as a cover for the actual plutocracy. Although the framework of cognitive capitalism witnesses a certain movement towards meritocratic principles of the formation of elites, it simultaneously prepares ground for the emergence of a kind of “trap of meritocracy”, when, for a number of reasons, the layer of “educated and talented” turns into a hereditary caste. At the same time, according to the author, the future hardly belongs to meritocrats, no matter how well they fit into the realities of the high-tech economy. New developments in artificial intelligence are jeopardizing many forms of intellectual work, leading to a cut-throat competition for a decreasing number of high-paying jobs. In turn, the bourgeois world of labor is being replaced by a post-capitalist world of idleness and creativity as the production of intangible goods. The rapid development of social media makes emotional and social intelligence, as well as the ability to achieve popularity and influence through media activities, increasingly important. In other words, modern technology makes life difficult for cognitive elites, while opening up enormous opportunities for very different social groups. In this regard, the author puts forward a hypothesis according to which popularity will become a key criterion for the formation of elites in the foreseeable future rather than merit. Postcapitalist personocracy will gradually replace bourgeois meritocracy, which, however, does not exclude the possibility of the preservation of the myth of meritocracy, implying that those who can skillfully attract attention will be assigned various merits.
