Stages of renal artery stenosis: a hypothesis based on ultrasound findings: A narrative review
Authors: Park Byung Kwan
Published: March 2023

Current ultrasound (US) scanners can directly detect renal artery stenosis (RAS) in which the degree is the same irrespective of heart beat. Frequently, however, blood pressure or renal function is not improved because the stage of RAS is too late. Therefore, RAS should be early detected and thus the radiologists are familiar with US features of early, intermediate, and late RAS. Atherosclerosis is the most common etiology to RAS and begins inflammation from the intima of renal artery. Accordingly, we can hypothesize that there are multi-stages going to the final RAS. At early stage, RAS can be detected on diastolic phase alone. However, at intermediate stage, it begins to be seen on systolic phase and is more severe on diagnostic phase than that at early stage. Finally, at late stage, RAS is seen at the same degree regardless of heart beats because the stenosis is fixed due to fibrosis. The purpose of this review is to introduce a hypothesis on the stages of RAS, to show the renal artery US features of each stage, and to compare US and angiography in terms of RAS detection.
Tau positron emission tomography in tauopathies: A narrative review
Authors: Lee Hyunjong , Gu Yuna , Seo Sang Won , Moon Seung Hwan
Published: March 2023

Aggregation of misfolded tau in the brain is a major pathological feature common in various neurodegenerative disorders known as tauopathies, including Alzheimer’s disease, progressive supranuclear palsy, corticobasal syndrome, and dementia with Lewy bodies. Tauopathies are collection of diseases with varied overlapping symptoms and complicated manifestations. Consequently, it is crucial to be able to assess tau deposits in vivo. Over the past decade, tau-specific radioligands for positron emission tomography (PET) have been developed and tested, including first-generation compounds (e.g., 18F-THK5317, 18F-THK5351, 18F-AV1451, and 11C-PBB3) and second-generation compounds (18F-MK-6240, 18F-RO-948, and 18F-PI-2620). With the recent advances of tau PET tracers, assessing the pattern of tau deposition in vivo is possible. These methods will allow accurate diagnosis of tauopathies and monitoring of disease progression. In this mini review, we summarize current findings from studies using tau PET tracers regarding neuropathological characteristics, clinical implications, and potential applications of tau PET. We also discuss methodological considerations for appropriate use of these technologies and discuss what has been learned from these findings.

Authors: Bryc-Walczak Katarzyna , Bryc Władysław , Nowicki Michał
Published: March 2023

Background: Transurethral resection of the prostate gland (TURP) frequently leads to the de-velopment of dilutional serum sodium decrease. Copeptin has been established as a surrogate marker of vasopressin and is measured for clinical assessment of various sodium and water dis-turbances. This study aims to assess the utility of serum concentration of copeptin and N-terminal prohormone of brain natriuretic peptide (NT-proBNP) for prediction of post-TURP al-terations of serum sodium concentration.Methods: Forty-three patients with benign prostatic hyperplasia undergoing TURP were enrolled. Serum sodium and copeptin were measured before the procedure, then 12 hours after its com-pletion. NT-proBNP was assessed at baseline. The total amount of fluids and sodium adminis-tered intravenously and used to flush the bladder during TURP was calculated in each patient. Receiver operator characteristic (ROC) curve analysis was used to determine value of copeptin and NT-proBNP for prediction of serum sodium decrease after TURPResults: In forward stepwise multiple regression analysis of serum copeptin before surgery and the duration of TURP explained the significant portion of the sodium concentration variation 12 hours from the start of the surgery. ROC curve analysis showed that serum copeptin before sur-gery predicted development of hyponatremia 12 hours after TURP (area under the curve, 0.775; 95% confidence interval, 0.62–0.89; p < 0.001) with a cut-off point of >78.6 pg/mL with 77% sensitivity and 64.7% specificity. Serum NT-proBNP before surgery did not predict hypo-natremia 12 hours after TURP.Conclusion: Serum copeptin before TURP surgery, but not NT-proBNP, may be a clinically use-ful marker of the risk of serum sodium decrease after TURP.

Published: March 2023

Background: Although multiple factors influence the risk of major adverse cardiovascular events (MACE), the effects of socioeconomic status on MACE in the presence and absence of renal dysfunction (RD) have not been comprehensively explored in Korea. Methods: We examined the effects of socioeconomic status on MACE in individuals with and without RD. The data of 44,473 Koreans from 2008 to 2017 were obtained from the Health Care Big Data Platform of the Ministry of Health and Welfare in Korea. Their socioeconomic status was assessed using a socioeconomic score (SES) based on marital status, education, household income, and occupation. The incidence of myocardial infarction (MI), stroke, and death was compared according to SES level (0–4). Multiple linear regression analysis was used to evaluate the hazard ratios and 95% confidence intervals for outcomes based on participant SES. Results: MI risk was only affected by education level. The participants’ income, education, and SES affected their stroke risk, whereas death was associated with all four socioeconomic factors. The incidence of stroke and death increased as SES worsened (from 0 to 4). SES was positively related to risk of stroke and death in participants without RD. SES did not affect MI, stroke, or death in participants with RD. Conclusion: A low socioeconomic status is associated with risk of stroke and death, especially in individuals without RD.
Upregulation of NADH/NADPH oxidase 4 by angiotensin II induces podocyte apoptosis
Authors: Ha Tae-Sun , Seong Su-Bin , Ha Dong-Soo , Kim Seung Jung
Published: March 2023

Background: Angiotensin II induces glomerular and podocyte injury via systemic and local vasoconstrictive or non-hemodynamic effects including oxidative stress. The release of reactive oxygen species (ROS) from podocytes may participate in the development of glomerular injury and proteinuria. We studied the role of oxidative stress in angiotensin II-induced podocyte apoptosis.Methods: Mouse podocytes were incubated in media containing various concentrations of angiotensin II at different incubation times and were transfected with NADH/NADPH oxidase 4 (Nox4) or angiotensin II type 1 receptor for 24 hours. The changes in intracellular and mitochondrial ROS production and podocyte apoptosis were measured according to the presence of angiotensin II.Results: Angiotensin II increased the generation of mitochondrial superoxide anions and ROS levels but suppressed superoxide dismutase activity in a dose- and time-dependent manner that was reversed by probucol, an antioxidant. Angiotensin II increased Nox4 protein and expression by a transcriptional mechanism that was also reversed by probucol. In addition, the suppression of Nox4 by small interfering RNA (siRNA) reduced the oxidative stress induced by angiotensin II. Angiotensin II treatment also upregulated AT1R protein. Furthermore, angiotensin II promoted podocyte apoptosis, which was reduced significantly by probucol and Nox4 siRNA and also recovered by angiotensin II type 1 receptor siRNA.Conclusion: Our findings suggest that angiotensin II increases the generation of mitochondrial superoxide anions and ROS levels via the upregulation of Nox4 and angiotensin II type 1 receptor. This can be prevented by Nox4 inhibition and/or antagonizing angiotensin II type 1 receptor as well as use of antioxidants.

У статті наводяться результати математичного моделювання статичних та квазістатичних електричних полів надмалої потужності, яке проводиться шляхом розв‘язання системи аналітичних рівнянь, що базуються на диференціальних рівняннях Лапласа. Особливістю цієї моделі є те, що в ній враховується динаміка зміни електричного поля та його розмірів у процесі сканування останнього поліелектродним циліндричним давачем, а також вплив зовнішніх кліматичних факторів (температури, відносної вологості) та електромеханічний вплив з боку досліджуваної поверхні. На основі проведеного аналітичного моделювання складено комп‘ютерну модель, в основу якої покладено метод скінченних елементів, а програмне забезпечення моделі створено на об'єктно-орієнтованій мові програмування Python 3.10. Розроблена модель дозволяє з високою точністю (розбіжність між даними математичної та аналітичної моделей не більша 2,15 %, а з експериментально отриманими даними – не перевищує 7,15 %), а також у режимі реального часу будувати графіки розподілу напруженості електричного поля та електричного заряду, а також визначати діапазони параметрів цих полів, дотримання яких не призводить до електричного пробою.

Розвиток обчислювальної техніки напряму залежить від розвитку методів синтезу компонентів цифрової обчислювальної техніки, тому автоматизація процесу спостерігається і при розробці мікросхем. Для синтезу моделей схем широко використовується булева алгебра і однією із проблем, що виникають при цьому, вважається залежність складності реалізації певної схеми від кількості змінних булевої функції, що її реалізує. Виходячи з цього, можна стверджувати, що збільшення кількості змінних у функціях, які потребують мінімізації, вимагає пошуку нових або вдосконалення існуючих методів мінімізації булевих функцій, що будуть простими у застосуванні, наочними та матимуть можливість автоматизувати реалізацію процесу мінімізації. Залишається актуальною задача розробки ефективних методів мінімізації булевих функцій для моделювання схем, що мають лінійну та поліноміальну залежність швидкості моделювання від кількості змінних булевої функції, що реалізується. Об’єкт дослідження – процес мінімізації булевих функцій, які використовуються при побудові схем цифрових автоматів. Метою роботи є практична реалізація методу мінімізації булевих функцій на основі направленого перебору при збільшенні кількості змінних. Задача, яка розглядається в цій роботі, полягає в розробці та реалізації методу мінімізації булевих функцій, який дозволить мінімізувати булеві функції на основі направленого перебору, розрядність яких перевищує десять змінних, а також збільшити ефективність пошуку при склеюванні імплікант з великою невизначеністю на наборах функцій. Оскільки всі існуючі методи мінімізації стикаються з проблемою громіздких обчислень при збільшенні кількості змінних, для дослідження було вибрано саме метод направленого перебору, який є досить ефективним при великій невизначеності на наборах. На основі проведених розрахунків визначено, що розглянутий метод мінімізації булевих функцій дієвий та простий у застосуванні. Основною його перевагою є можливість реалізації засобами обчислювальної техніки, а покладений в основу направлений перебір дозволяє зменшити вимоги до програмно-апаратних ресурсів систем автоматизованого проектування.
Comparative analysis of measurement accuracy characteristics
Authors: Zakharov Igor
Published: March 2023

The parallel coexistence of the error theory and the concept of uncertainty in Ukraine for almost 30 years has brought about constant discussions and raised the issue of their analysis and comparison.

The concept of uncertainty is the product of an international standardization process for the evaluation of measurement accuracy. The development of the concept was based on analysing and generalizing the documents on error evaluation, relevant in different countries, therefore many elements of both approaches coincide. Nevertheless, there are a number of mathematical, terminological, and conceptual differences that are considered in this paper.

It should be noted that while the development of the error theory stopped at the end of the 90s of the last century, the concept of uncertainty has been successfully developing since then thanks to the activities of the JCGM and a number of other international organizations. Along with the GUM, a variant of implementing the model approach has been introduced based on the Monte Carlo method, an empirical approach has been developed, and the revision of the GUM has been initiated based on the Bayesian inference.

Nevertheless, both concepts have internal contradictions and shortcomings, with which even their creators themselves agree.

Therefore, the task of theoretical metrologists is to develop a unified theory for evaluating the accuracy of measurements, eliminating the shortcomings of both approaches.

Quantitative differences of accuracy estimates in the theory of errors and the concept of uncertainty are considered, which are related to the ways of expressing and summing the components, as well as obtaining interval accuracy estimates.

In view of the imperfection of normative documents on the error theory, as well as the widespread use of the ISO/IEC 17025 standard in Ukraine, it is advisable to reformulate the curricula for metrological specialities replacing the theory of errors with the concept of uncertainty.

Die bella figura – zur Pragmatik eines italienischen Schlüsselkonzepts
Authors: Held Gudrun
Published: March 2023

The concept of bella figura is so inherent to Italian culture that it represents the quintessence of Italian identity. Demonstrating a good self image is not only fundamental to social relations and affiliation, but constitutes a pragmatic knowledge presumed to be carried out in everyday interaction and reflected in (non)verbal communication. With the exception of tourist guides and lay comments on the internet, the concept of a bella figura (and its opposite brutta figura) has never been the subject of scientific research. Therefore, its nature will be studied from the perspective of current pragmatic theories, identifying it as impression management and relational work and discussing it in relation to face and (im)politeness. Complemented by a semantic study, the concept reveals an ambivalence between the aspiration to an aesthetic-emotional ideal and the execution of an ethical-moral principle. With reference to the cultural-historical development, it appears that the expressions fare bella/brutta figura serve as a means of evaluation, whereby, identified in communicative use, they are suitable as an important analytical tool that makes metapragmatics a useful research method.

Published: March 2023

The purpose of this study was to explore the current status of elementary AI education, the interest shown by elementary teachers in AI education, and topics related to elementary AI education, to obtain basic data on the direction of AI education policy and ways to revitalize AI education. After deleting duplicate posts and posts unrelated to the research topic in the post data collected by IndiSchool, a representative online community for elementary school teachers was established, followed by conducting basic and text-mining analyses using 454 posts as the research subject.
First, to explore the current status of elementary AI education, the trend according to the period of AI-related postings was examined. From analyzing the trend of posts related to AI education uploaded to the online community of elementary school teachers, it was evident that interest in AI education had increased since 2020.
Next, to analyze the interest in AI education expressed by elementary school teachers, the frequency of words from text mining was examined and keywords related to AI education were selected. Based on these selected keywords, the class types and class activities in which AI education was mainly operated, its active use on educational platforms, and the importance of copyright issues were established.
Finally, a topic modeling analysis of text mining was conducted to explore AI education-related topics within the online community of elementary school teachers and keywords for each topic. First, the optimal number of topics was determined as three, and after organizing the top 30 words according to topic, keywords for each topic were selected and the name of each topic was established: “design and operation of AI class,” “development of AI class competency,” and “utilization and development of AI class content.” Ultimately, examples of posts corresponding to each topic were presented.
Study on Upcycling-based clothing education in practical arts
Authors:   The Korean Association of Practical Arts Education, Lee Sung-sug
Published: March 2023

This study was conducted to suggest a method of clothing life education through upcycling. The content of education related to recycling was analyzed for six types of textbooks, and educational materials for making upcycling products were proposed based on this textbook analysis. The results of analyzing the content of education related to the recycling of practical arts and textbooks were as follows. In the practical textbooks for 5th grade, the units containing content related to recycling were the core concepts of “management” (6 types), “creation” (1 type), and “efficiency” (1 type), of which management included the most. In the 6th grade, the core concepts were “living culture” (4 types), “life planning” (1 type), “innovation” (3 types), and “sustainability” (3 types), of which living culture included the most. Most of the recycled materials that appeared in the 5th and 6th grade practical textbooks were clothes, plastic bottles, and milk cartons, while the items to make included bags, cushions, pockets, flower pots, and pencil holders.
To propose upcycling-based clothing education materials, the following were suggested as recycled materials to use from the textbook analysis: T-shirts (and yarn cut from T-shirts), towels, coffee sacks, blankets, and wrapping paper ribbons.
Up-cycling fashion design techniques and clothing-related content of the 2015 revised practical curriculum were considered, from which eight were suggested: weaving with sock necks, making sock rings to make baskets, cutting T-shirts and knitting them, cutting and twisting towels to make potholders, making fringe pockets from T-shirts, making scrubbers from coffee sacks, creating brooches from packing ribbons, and duvet fabric. Furthermore, there was a proposal to make coasters using cotton. This study had the limitation of not conducting a verification process on the developed data. However, at a time when interest in the environment (such as climate change) is increasing, recycling classes can be used as basic data for clothing education that considers the environment. Moreover, it is envisaged that it will be necessary to apply the data developed in the future.

Histiocytic sarcoma (HS) is uncommon malignant neoplasia of round cells with marked predilection in Rottweiler and Bernese Mountain. The disseminated form, which mainly affects the spleen, lungs, lymph nodes, bone marrow, skin, and subcutis, presents a quick and aggressive clinical behavior. Hemangiosarcoma (HAS) is a malignant neoplasm of endothelial vessel cells commonly reported to affect the right atrium of dogs' hearts. A male Rottweiler, five years old, presented flaccid paraplegia and progressive muscular atrophy in the temporal, masseter, and limbs muscles; Due to the clinical stage of the animal, euthanasia was conducted. During the necroscopic examination, it was noticed that several masses presented different sizes; some were whitish, and others were reddish and spread in multiple organs (lungs, heart, spleen, stomach, kidneys, brain, medulla, skeletal muscle, and pre-scapular lymph node). Microscopically, in some organs such as the stomach, right ventricle, lungs, and medulla, it was noticed a proliferation of myeloid cells, highly cellular, with poor demarcation, no encapsulation, and with the infiltrative growth pattern of cells with high pleomorphism. Numerous tumoral emboli were observed in the spleen, brain, skeletal muscle, and lymph node. These cells were submitted for immunohistochemistry and were positive for CD18 (HS antibody). In the right atrium, liver, and kidney it was observed malignant and infiltrative endothelial proliferation (HSA) and emboli in the medulla. Therefore, we conclude that both neoplasms (HS and HSA) cause the animal's paraplegia due to their embolism and metastasis to the spinal cord and skeletal muscle.

Clinical History: A 5-year-old, Holstein-Friesian dairy cow was evaluated by a veterinary practitioner for a 30-day history of unilateral exophthalmos (Fig. 1). After 15 days, the cow presented lameness followed by progressive weight loss and pelvic limbs paresis, culminating in persistent sternal recumbency (Fig. 2). The superficial inguinal lymph nodes were enlarged. Due to the poor prognosis, the cow was euthanized and submitted to a postmortem examination. Gross Findings: The cow was in poor body condition with mild amounts of subcutaneous and visceral fat stores. The oral and conjunctival mucous membranes were pale. There was severe exophthalmos in the right eye, caused by a soft, homogenous, white to yellow mass (6 cm in diameter) (Fig. 3) in the retrobulbar space. Similar irregular masses were seen in the left renal pelvis, partially effacing the renal parenchyma, and in the epidural space, circumferentially surrounding the pachymeninges (extradural location) (Fig. 4) of the lumbar segment of the spinal cord. The superficial inguinal lymph nodes (supramammary) were markedly enlarged and, on the cut surface, had homogenous white to yellow discoloration and loss of the corticomedullary junction. Multifocal areas of the abomasum wall were moderately thickened and expanded by a soft, homogenous, white to yellow masses. No significant alterations were observed in other organs.

Languages change with time. As a result, new structures appear, and new approaches are developed in them. Language is a link in decoding forms of cognition between the past and the present – and the role of proverbs here is really significant. In every language, proverbs carry the color of the era. They are directly related to folk traditions and help to preserve history, culture, and the mentality of society. Phraseological units such as proverbs differ across cultures, although similar forms can sometimes be found in various sociocultural contexts. Likewise, the system of conduct rules is expected to be different from society to society, since the values of people of each individual national group are determined by their traditions and culture. The present article is based on a comparative analysis of proverbs in the Russian, Ukrainian and Hungarian languages. Proverbs that describe labor principles and rules of conduct in everyday social life were selected from (bilingual) dictionaries and the Internet resources with the aim of identifying the main similarities and differences between Russian, Ukrainian and Hungarian societies. A few proverbs regarding leisure time and friendly relations were also analyzed as linking subtopics to the concepts of labor and conduct. Some proverbs containing an animal-element that are used to describe humans’ behavior also appear in the present work. The study shows that the national and cultural components of proverbs depict physical activity and other realities of communities, but proverbs might have their own national coloring and moral content. In our study, proverbs are viewed as statements that are often rhymed, usually have two parts, and express a complete thought. The present paper is of practical importance as the research results can be applied for theoretical courses in comparative linguistics, especially in courses on the study of proverbs.
