Bu çalışmada gerçek zamanlı simülasyonlarda uçak sayısına ve hava sahası yapısına bağlı olarak tasarlanan dört farklı düzeydeki görev zorluğuna (kolay, orta, zor, çok zor) sahip senaryolardaki egzersizler boyunca, simülasyon eğitimini almış ve almamış (deneyimli-deneyimsiz) iki farklı grup üzerinde zihinsel iş yüklerinin çok boyutlu olarak incelenmesi için iki aşamalı bir deneysel süreç yürütülmüştür. Çalışmanın ilk aşamasında simülasyon öncesi katılımcıların reaksiyon süreleri FitLight Trainer sistemi kullanılarak üç farklı protokol üzerinden değerlendirilmiştir. Deneyimli ve deneyimsiz gruplar arasında reaksiyon süreleri bakımından anlamlı bir farklılık gözlenmemiştir. İkinci aşamada ise reaksiyon süreleri homojen olan bu grupların gerçek zamanlı simülasyon senaryolarında yaptıkları hata sayıları ve elde ettikleri performans skorları birbirleri ile kıyaslanmıştır. %90 güven seviyesinde deneyimli grup daha az hata yapmıştır. Ayrıca senaryoların farklı zorluk derecesinde olması hata sayılarında istatistiksel olarak farklılık yaratmıştır. Kolay-orta senaryolarda öğrenciler zor-çok zor senaryolara göre istatistiksel olarak anlamlı derecede daha az hata yapmışlardır. Bununla birlikte performans skorlarının senaryo zorluk derecelerine göre değişimleri incelenmiş ve performans skorları arasında anlamlı farklılık olduğu ortaya çıkmıştır (p-value=0,00 < 0,05). Kolay-orta senaryolarda zor-çok zor senaryolara göre öğrencilerin performans skorları anlamlı derecede yüksek çıkmıştır. Çalışma sonuçlarına göre hata sayıları ve performans skorlarının birbirini desteklediği görülmüştür. Senaryoların zorluk derecelerinin bilişsel iş yüküne (hata sayıları, performans skorları) etkisi olduğu söylenebilir.

Published: January 2023

Marfan syndrome is a dominant autosomal genetic disease of the connective tissue, leading to various complications. Cardiovascular complications are the main ones, with dilation of the aorta and aortic dissection which is the main cause of death. Double dissection with different sites of departure is scarcely reported by the literature. We reported the case of a 22-year’s-old young patient admitted for acute chest and abdominal pains, and cardiogenic shock. Investigations reported a double dissection of the aorta with a recent one of type A and an old one of type B. Ghent diagnostic criteria were used to allow the diagnosis of Marfan disease. Surgical management corrected successfully the type A dissection. Early diagnostic and adequate management of aortic complications can reduce the high mortality rate of patients with Marfan syndrome.

Authors: Janštová Vanda , Zdobinská Helena
Published: January 2023

This study contributes to description of teaching changes resulting from COVID-19 epidemic. It focuses on online teaching of practical exercises in science subjects from pupils’ and teachers’ perspectives. Views on the distance learning of practical exercises were obtained from Czech lower-secondary school pupils (n=543) and science teachers (n=24). Most teachers conducted science practicum classes using a combination of synchronous and asynchronous methods and rated support from school management as rather adequate. Teachers assigned fewer hands-on activities, specifically experiments, observations, and activities resulting in a product, in distance teaching than in face-to-face lessons, although they rated them as the most useful. Pupils found experimentation and observation to be the most interesting and useful, followed by activities that result in a product (e.g., herbarium). Pupils generally preferred the present form of practical activities.

Published: January 2023

In the context of cultural anthropology, people have known various mathematical activities, such as counting, measuring, and weighting, which have different terms based on each culture. We understand that mathematics emerges from people activities in responding to the existence of their environment. Sasak people conduct various cultural activities in their daily life. One of which is in agriculture and in the form of traditional arts, therefore, this study aims to build mathematical conceptions by exploring the activities of Sasak culture that can be integrated into mathematics learning contextually. This study was an ethnographic research. Data were collected through various literature studies, field observations, and interviews with savvy informants regarding Sasak culture, traditional farming system, and Sasak traditional arts. Research results indicated that the culture of Sasak people relevant with principles and characteristics of Realistic Mathematics Education (RME) is a learning approach that can be integrated, both explicitly and implicitly

Published: January 2023

This study investigated the impact of Entrepreneurial-Motivated-Approach in bridging gender disparities in achievement among senior secondary chemistry students. The study adopted pre-test, post-test nonequivalent quasi-experimental design. The sample comprised 118 senior secondary 2 chemistry students with 58 students in the experimental group (30 male; 28 female) and 60 students in the control group (27 male; 33 female) in two intact classes from two senior secondary schools in Education District V, Lagos State, Nigeria. The experimental group was taught using Entrepreneurial-Motivated-Approach while the control group was taught the same concepts for a period of six weeks using the conventional lecture method. Chemistry Cognitive Achievement Test and Chemistry Practical Achievement Test were used for data collection after validated by experts in test and measurement, and chemistry entrepreneurship. The reliability coefficients of the CCAT and CPAT were established using K-21 which yielded 0.87 and 0.76 respectively. The research questions were answered using mean and standard deviation while the hypotheses were tested using multiple analysis of covariance (MANCOVA) at 0.05 level of significance. Results revealed that gender had no significant effect on the students’ cognitive achievement [F(1,56)=.02; p>0.05] and practical achievement [F(1,56)=.48; p>0.05] in chemistry when taught using Entrepreneurial-Motivated-Approach. The study therefore recommended among others that Chemistry teachers should make effective use of Entrepreneurial-Motivated-Approach in chemistry instructions and the Curriculum planners should ensure the incorporation of entrepreneurial modules in the learning experience of senior secondary chemistry curriculum and textbooks to ensure skills acquisition among chemistry students.

Olaudah Equiano ou Gustavus Vassa: o que há em um nome?
Authors: E. Lovejoy Paul
Published: January 2023

Este artigo trata da polêmica sobre os significados do nome do autor de The Interesting Narrative of the Life of Olaudah Equiano, or Gustavus Vassa, the African (Londres, 1789). A polêmica reside nas formas como Equiano ou Vassa, em parte se relacionava com o seu local de nascimento. A escolha do nome que ele cotidianamente usava provoca questões sobre o modo como os estudiosos querem compreender o autor, mas também como o próprio homem se representava na época em que viveu e escreveu sua autobiografia. Argumento que o autor de The Interesting Narrative usou seu nome de nascimento, Olaudah Equiano, como prova de sua origem africana, e não como um nome pelo qual queria ser conhecido, Gustavus Vassa. Assim, o dilema é porque os estudiosos se referem a ele por seu nome africano, quando ele optou por não o fazer. Sugere-se que o uso do nome de nascimento tem mais a ver com a política de representação e correção política das gerações posteriores de estudos, não com a intenção do homem. A razão para o debate sobre seu nascimento tem mais a ver com o confronto atual entre erudição literária e interpretação histórica do que com possíveis interpretações e representações errôneas do passado.
Ritos de iniciação e educação formal em Moçambique: um diálogo possível para o fim da violência contra as mulheres?
Authors: Machava Paula , Cimalawoonga Rajabo
Published: January 2023

A crescente intolerância e violência contra as mulheres em Moçambique desafia-nos a questionar quando e como perdemos os valores éticos presentes em algumas práticas culturais “tradicionais”. Durante o colonialismo histórico, estas práticas foram consideradas barbárie, por isso, deviam ser eliminadas. Atualmente, alguns discursos feministas, dos ativistas dos direitos humanos e das ONG´16s nacionais e internacionais são também apologistas dessa eliminação por considerá-las opressoras para as mulheres. Apesar dessa pressão, estas práticas continuam presentes na sociedade, não só pela sua importância identitária étnica-social, mas também pela complexa dimensão ética que carregam. Neste texto pretendemos ensaiar, a partir da articulação dos valores éticos transmitidos nos ritos de iniciação femininos e masculinos Yao com os escolares, uma sociedade em que as mulheres têm agência e são livres de violência.

The Analysis of Teacher Policy in Indonesia
Authors: Ariawan Soni
Published: January 2023

The present qualitative research aims to investigate teacher policy in Indonesia viewed from international teacher standard revealed in the Teacher Policy Development Guide of United Nation. There are four dimensions as the focus of analysis: underpinning values, the purpose, key principles of implementation and key dimension for comprehensive teacher policy. Content analysis was employed to gauge the data from the rule of law on teacher and lecturer in Indonesia number 14 year 2005 about teacher and lecturer that is more specifically broken down into policy number 74 year 2008 about teacher. In addition, the researcher carefully investigated four dimensions revealed in the Indonesian teacher policy document as well as highlighted the results in the form of table. The findings confirmed that Indonesia has a comprehensive policy dealing with education system and teacher which reflects several international standards and features as well as accommodates local values. On the other hand, teacher policy in Indonesia is still presented in general language instruction without a specific implementation guide. To conclude, both policies have different languages and terminology in some extend but it has the same basic idea in terms of human right and democratic values both in the context of teacher policy and education in general.�

On Capability Sets
Authors: Shankar Sati
Published: January 2023

It is said that the command over commodities give command over characteristics. The point is that, mere possession of these characteristics does not tell us anything what the individual will be able to do with them. The reward of possessing these characteristics is determined by the way they are utilised. Therefore, we need to probe the "utilization possibilities" at a much deeper plane. In other words, we have to probe different functionings and their spaces which is the focal point of the Prof. Amartya Sen’s "Capability approach". Functionings are considered from two points of view, first, is to consider only those utilizabilities of characteristics which have actually been realised and ignoring other alternatives available for choice the second and much wider approach is to consider all the possibilities of utilizability of different characteristics, i.e. to consider the whole set of functionings. Keywords: Psychophysics, Biophysics, Information theory, Biogenesis, Topology, Symmetry, molecules, cognitive, entropy, Functioning, proximity, neural, Amartya Sen

Published: January 2023

Цифровые технологии, применяемые в медицине и фармации, способствуют оптимизации процессов оказания медицинской и фармацевтической помощи, снижению числа врачебных ошибок, повышению уровня конкурентоспособности аптек. Фармацевтическое консультирование как одна из составляющих розничной торговли в условиях аптечной организации относится к основным функциям провизора и фармацевта по оказанию фармацевтической помощи посетителям аптек. Сложность эффективного сочетания социальной и экономической направленности деятельности аптеки предполагает создание условий более быстрого и качественного информирования посетителей о возможных способах оказания медицинской и фармацевтической помощи. Одной из распространенных проблем, с которой пациенты обращаются в аптеку, является важность сохранения зрения и своевременного применения соответствующих мер при развитии синдрома «красного глаза». Данная задача решается внедрением в деятельность аптечной организации цифровых технологий, разработкой программного обеспечения алгоритма консультирования. Программное обеспечение «Аптечный консультант «Красный глаз» разработано с использованием языка программирования Java на платформе Java SE, также применена СУБД PostgreSQL. Программный продукт помогает провизору проинформировать пациента о возможном побочном действии принимаемого им ранее препарата на орган зрения, осуществить поиск препарата, рекомендуемого в данной ситуации, а также воспользоваться информационными материалами.
Влияние поверхностного пластического деформирования на структуру и механические свойства рабочего слоя биметаллического инструмента
Authors: Лаврентьев А. Ю. , Дожделев А. М. , Кондратьев С. Ю.
Published: January 2023

Исследовано биметаллическое соединение, полученное поверхностным пластическим деформированием (ППД) в процессе наплавки слоя инструментальной стали Р2М8 на заготовку из конструкционной стали 30ХГСА по двум разным технологиям. Определены структура и микротвердость образцов полученного биметаллического инструмента. Установлено, что ППД биметалла при наплавке в процессе охлаждения в интервале 350 - 200 °C способствует эффективному превращению в сталях, составляющих биметалл, остаточного аустенита в мартенсит деформации, а также получению более дисперсной структуры без образования трещин. При этом по сравнению со стандартной технологией (без ППД) твердость наплавленной с использованием ППД инструментальной стали Р2М8 увеличивается на 170 HV0,2, а конструкционной стали 30ХГСА - на 200 HV0,2 в зоне термического влияния на расстоянии 3,0 - 3,5 мм от границы сплавления биметалла, что должно обеспечить высокую износостойкость инструмента.

Published: January 2023

Work immersion is required before graduation for senior high school students that aims to prepare the students for college life, particularly for humanities and social sciences (HUMSS) students. Despite the restriction in face-to-face classes and prohibiting industry-based experience, teachers need to build the students’ awareness, ignite their interest and uplift their readiness for college courses. So, teachers decided to implement work immersion via a blended modality wherein students experience school-based and online work immersion. This study aimed to build the HUMSS students’ awareness, interest, and readiness for college courses. A practical action research design was utilized to measure the variables before and after the work immersion implementation. Hence, survey questionnaires and interviews were the data collection tools employed to collect both quantitative measures and qualitative descriptions of experiences. The findings show that the students have low awareness, interest, and readiness for their preferred college courses before implementing work immersion in a blended modality. However, after two months of implementation, all variables become high and significant differences exist before and after the implementation. The work immersion using a blended modality effectively increased students’ awareness, interest, and readiness for college courses. However, they suggested having more webinars and activities, more learning materials, frequent face-to-face interactions, parents’ involvement during the webinar, and a student committee for communication.

Published: January 2023

The purpose of the research is to test blood-sucking dipterans collected in the Tyumen Region for genetic material of viruses that cause dangerous diseases in live-stock animals.Materials and methods. From May to October 2021, blood-sucking insects of the Diptera order whose species membership was established by tabular keys were collected on pastures and farms in ten Tyumen Region districts. In 60 samples formed from the captured insects according to the taxonomic affiliation and the period and place of collection, the presence of genetic material of the leukemia provirus and the dermatitis nodularis virus of cattle (bovine) and the African swine fever virus was evaluated by polymerase chain reaction (PCR) in real time.Results and discussion. Adult insects collected for the PCR analysis were blood-sucking flies (family Muscidae, genus Stomoxys), mosquitoes (family Culicidae, genus Aedes), midges (family Simuliidae, genera Byssodon and Schoenbaueria), horseflies (family Tabanidae, genera Hybomitra, Tabanus and Haematopota), and biting midges (family Ceratopogonidae, genus Culicoides). As a result of the PCR testing of the samples for the bovine leukemia provirus DNA, 1 out of 13 samples of Stomoxys spp. (7.7%) and 1 of 13 samples of Hybomitra spp. (7.7%) were positive. The bovine leukemia provirus DNA detected in blood-sucking insects indicates the presence of this pathogen in the insect collection area as well as their possible involvement in its spread. Further research is needed on the Stomoxys spp. and Hybomitra spp. vector competence in vivo, considering natural and climatic features of the Tyumen Region.

Published: January 2023

The purpose of the research is to study dynamics of the peripheral blood cell composition during experimental infection of hens with Trichinella pseudospiralis.Materials and methods. . Two groups were formed according to the principle of analogues, experimental and control, of 10 and 6 laying hens, respectively. The experimental birds were weighed, and the isolate of T. pseudospiralis larvae was administered intragastrically at a dose of 2 sp./g of body weight (4000 thousand larvae per bird). Blood samples were taken from the axillary vein before and at days 4, 7, 11, 14, 18, 28, 35, 43, 53, and 61 after the infection. Hematological parameters (total number of erythrocytes and leukocytes, and hemoglobin concentration) were determined by established laboratory methods with subsequent calculation of the leukogram.Results and discussion. It has been established that trichinellosis in the hens caused by parasitism of non-encapsulated Trichinella spp. species does not affect the number of erythrocytes and hemoglobin in infected birds. Indicators of the Trichinella-associated process are cells in the granulocytic series, eosinophils. The onset of the body's reaction to the infection as expressed by eosinopenia was detected at day 7 after the infection. An increase in the relative content of basophilic and eosinophilic granulocytes was recorded in the hens’ blood from day 18; such parameters reached their maximum values on days 25 and 35, that corresponds to the migratory and muscular stages of the Trichinella-associated process. A relative and absolute quantitative decrease in these groups of cells was subsequently detected in the hens’ blood; however, these values were higher than the control non-infected hens during the entire follow-up (61 days). The dynamics of eosinophils and basophils circulating in the hens’ blood was due to the Trichinella-associated process staging and confirms the predominance of an allergic reaction in the nature of such disease.

The purpose of the research is to develop a methodology for Equiverm-2.0% paste used against equine parasite infections.The methodology provides a brief description of Equiverm-2.0%, mechanism of its action, pharmaco-toxicological properties, application, slaughter terms, and personal safety measures. Equiverm-2.0% antiparasitic paste consists of the active ingredient, ivermectin, and excipients; it is a light cream-coloured paste with a slight pine odor and sweetish taste. The drug is administered orally at a therapeutic dose of 0.2 mg/kg for the active substance. One gram of paste is equal to 1 mL in volume with 20 mg of ivermectin. Ivermectin in Equiverm-2.0% paste is in a dissolved form, and forms an intermolecular complex. The antiparasitic paste is packaged in disposable polyethylene syringe dispensers of 5 or 10 mL, respectively, 4 to 8 g each, per treated horse weighing 400-800 kg. When administered orally, the paste spreads in the oral cavity and the animal eats it with pleasure due to its sweetish taste. The drug is recommended for registration in the Russian Federation.

The purpose of the research is to evaluate the anthelmintic efficacy against gastrointestinal Strongylata infections of cattle and to give an economic justification for their use in Yaroslavl calves.Materials and methods. The studies were performed on the Ivanovo Region farms in 2018–2020. To determine the helminth infection in cattle, 604 animals undergone a coprological survey. The faeces were examined by the Fülleborn and Berman- Orlov methods. To determine the therapeutic efficacy of anthelmintics, 4 groups of animals spontaneously infected with Nematodirus sp. were formed. The first group of calves was dewormed with a drug containing 20% albendazole. The second group of animals received a drug containing eprinomectin, and the third, a combined anthelmintic containing praziquantel and ivermectin. The fourth group of calves was dewormed with an ivermectin containing drug. Results and discussion. On the Ivanovo Region farms, nematodirosis was recorded in the calves aged 6–12 months; the infection prevalence was 75.3% with an average intensity of 31.04±0.77 egg specimens in 1 g of faeces. The diets for calves on all of the farms were approximately the same; the average daily weight gain of the calves was 251.10±0.54 g. Drugs with the active substance of 20 % albendazole, eprinomectin, praziquantel + ivermectin, and ivermectin showed 100% extenseeffectiveness and intense-effectiveness. The release of the calves from Nematodirus spp. allowed to increase the average daily gain in the body weight of the Yaroslavl calves to 650±0.40 g. The applied anthelmintics showed an economic efficacy of RUB 12.7-13.1 for RUB 1 of costs.
Persistence of Poverty: How Measures of Socioeconomic Status Have Changed Over Time
Authors: Long Kody , Renbarger Rachel
Published: January 2023

Socioeconomic status (SES) is a common measure used to gauge social, cultural, and financial capital in scientific literature. Over time, SES research has produced an extremely wide and inconsistently used variety of SES variables and components. This study will review research that estimates SES and will examine common components and trends from the inception of its measurement to present data. A systematic review protocol was used to gather literature related to SES, and a historical analysis was conducted to examine the SES variables and their components that were most commonly used in the literature. Results displayed varying trends by decade, with earlier SES measures including components on social capital and more recent measures incorporating aspects of cultural and economic capital. Subjective perspectives of social class became more common toward the turn of the century, and few measures included components from more asset-based frameworks. The Big 3 measures (parental education, parental occupation, and income) have been common measures across time.

On the taxa of the genus × Trisetokoeleria (Poaceae) in the Russian Arctic
Authors: Koroleva T. M. , Petrovsky V. V.
Published: January 2023

An amplified description of the Siberian Arctic species × Trisetokoeleria taimyrica Tzvelev is compiled, based on the study and measurements of about 100 reproductive shoots (10 herbarium sheets) stored in the Herbarium of the Komarov Botanical Institute RAS (LE), including the neotype designated by the authors and 4 authentic herbarium specimens identified by N. N. Tzvelev. The main distinctive characters of the three species of the genus × Trisetokoeleria are given in the table, taking into account additional data on × T. taimyrica. The difficulty of recognizing the × Trisetokoeleria species in nature (the use of optics is necessary) is complicated by a weak difference in key features, primarily between T. gorodkowii (Roshev.) Tzvelev and T. taimyrica. The third species, namely T. jurtzevii Prob., clearly differs from the other two by pubescent (hairy) inflorescence branchlets and longer awns. × T. taimyrica differs from × T. gorodkowii by narrower, few-flowered panicles, glumes of slightly (vs. strongly) unequal length, and acuminate (vs. obtuse) lemma tips, and from × T. jurtzevii by glabrous stem, panicle branchlets and lemmas, as well as by shorter awns and narrower few-flowered panicles. Its differences from postulated parent species are as follows: from Koeleria asiatica Pers. — a short straight awn extending below the lemma tip (vs. extending from the very tip of the lemma, that is sometimes observed in K. asiatica), and glabrous stems and panicle branchlets; from Trisetum agrostideum (Laest.) Fr.) — a very short, straight awn extending slightly below the lemma tip (vs. twice articulated and extending slightly above ½ or at upper ⅓ of the lemma), as well as spike-like panicles. A map of the localities of the three × Trisetokoeleria species is compiled.

Lectotypification of the name Syringa (Ligustrina) amurensis (Oleaceae) and experience of specification of the data on herbarium specimens of the R. K. Maack’s Amur expedition of 1855
Authors: Krestovskaya T. V. , Sokolova I. V.
Published: January 2023

The original material of Syringa amurensis Rupr. is examined in the Herbarium LE. It is represented by 5 herbarium sheets of 3 gatherings made in 1855 by R. K. Maack’s expedition on the Amur River. We linked the data from some Maack’s specimens with the information from publications of 1857 and 1859 which dealt with those collections (see Appendix). The specimens have continuous chronological numbering, which allows to restore the dates and sites of collection for a significant number of the Maack’s gatherings from incomplete label data. In particular, this enabled us to make accurate dating of the S. amurensis specimens. The second-step lectotype of the name is designated.

У статті представлено результати впливу різних комерційних гібридів підщеп на ріст, розвитокта продуктивність безнасінного гібрида кавуна Кідман F1 в умовах Лівобережного Лісостепу України.2019–2021 рр. було досліджено вплив двох гібридів підщеп Пелопс F1 та Кобальт F1 на безнасіннийкавун гібрида Кідман F1, які формували різні фенологічні та біометричні показники рослин, таздійснювали вплив на врожайність. Щеплені рослини за фенологічними фазами розвитку відрізнялисявід нещеплених, так, на підщепі Пелопс F1 тривалість періоду від висадки розсади щепленого кавунадо достигання плодів становить 64–65 днів, що на 4–5 днів раніше за контроль. Щеплені рослини напідщепі Кобальт F1 не мали істотної різниці з контрольними рослинами за фенологічними фазамирозвитку. Біометричні вимірювання за три роки спостережень дозволили встановити значну різницюміж щепленими та нещепленими рослинами безнасінного кавуна. Щеплення забезпечило істотнобільшу вегетативну масу рослин. На підщепі Кобальт F1 листків було на 184 штук більше, а на підщепіПелопс F1 на 131 штуку, ніж у контрольних рослин. У щеплених рослин довжина головного стеблаістотно перевищувала контрольні рослини, так, на підщепі Кобальт F1 на 139,0 см довше, а на підщепіПелопс F1 на 119,0 см відповідно. Найбільша кількість пагонів першого та другого порядку було ущеплених рослин, так, на підщепі Кобальт F1, на 16 штук більше, а на підщепі Пелопс F1 на 12 штукбільше, ніж на контролі. За три роки випробувань на щеплених рослинах отримали вищий як ранній,так і загальний урожай. Найвищу урожайність 62,5 т/га отримали при вирощуванні кавуна гібридаКідман F1, щепленого на підщепу Кобальт F1, що на 24,1 т/га вище ніж на контролі, а на підщепіПелопс F1 53,5 т/га, що на 15,1 т/га перевищує контроль. Дослідження, проведені в умовахЛівобережного Лісостепу України, свідчать про доцільність використання двох підщеп – гібридаПелопс F1, та гібрида Кобальт F1, при вирощуванні безнасінного кавуна. Завдяки щепленню суттєвозростає урожайність відносно контролю як при отриманні ранньої продукції на 28–46 %, так ізагального врожаю на 39–63 % відповідно. За три роки випробувань спостерігається різниця міжсамими підщепами, так, на підщепі Кобальт F1 отримали на 9,0 т/га більшу врожайність порівняноз підщепою Пелопс F1. Доведена доцільність використання щеплених рослин у сучасних умовахвирощування.
