Authors: Alalawi Yousef , Alamrani Sultan , Albalawi Razan , Albalawi Ibrahim , Alwakeel Abdulazi , Al-Ghamdi Faisal , Alhamdi Muath , Al-Ruwaili Sultan
Published: June 2022

Background: Breast cancer is the second leading cause of death in women in the world. It can emerge at any age, but women above the age of 40 are more commonly affected.
Objective: To assess the public awareness of women toward breast cancer and the methods of screening, and to determine the relationship between the level of awareness with different sociodemographic factors.
Methods: This cross-sectional study was conducted among the women of Tabuk, Saudi Arabia, via a nonprobability sampling technique. Data collection was carried out through an online self-administered questionnaire.
Results: A total of 431 women were included in this study. Almost 40% were aged 18-30 years. The mean awareness score of the participants was 17.3 ± 3.5 (SD) out of a total of 24 points. More than half of the females revealed good awareness (52.7%). In addition, about 72.6% of the women knew that breast cancer is very common and most of them admitted that different methods of screening are not harmful but useful. Breast lumps was most frequently recognized symptom of breast cancer. Furthermore, significant associations were found between the level of awareness and age, marital status, occupational status, and age of menarche.
Conclusion: The results showed an intermediate level of breast cancer awareness and screening methods. However, this level is still insufficient. Therefore, educational interventions are recommended to provide awareness of breast cancer. The above-listed associated factors should be considered while applying these interventions.

Theoretical and methodological foundations of comparative analysis of healthcare systems in the world
Authors: Travnikova Darya Aleksandrovna
Published: June 2022

The article examines and examines the research of foreign specialists in the field of economics and healthcare organization, who used a comparative approach to analysis in their works. The article examines the features of the application of mechanisms and models of health management characteristic of different countries, studied the experience of the UK, USA, Sweden, Finland, Germany and Japan. The article systematizes the views of scientists on the problem of applying comparative research in the field of healthcare. The article defines generalizations that characterize almost all existing healthcare systems in the world today. Studies are shown that allow us to identify common principles of the organization of health systems in the world, but, at the same time, to identify specific regional and national conditions that become the basis of existing regional, subnational and national health systems. In Russia, at the same time, the healthcare system includes an insurance component and private medicine. The development of the modern healthcare system in Russia can be assessed as not very positive, since with a general reduction in the number of medical personnel and the number of medical institutions in the 90s, this trend is currently continuing, albeit in a more smoothed form. A common place in the development of the healthcare system remains the growth of paid medical services and the orientation of sectoral public authorities in the direction of the development of the health care market with the strengthening of the role of the private sector. The healthcare system is undergoing, on the one hand, an upswing due to the growth of investments caused by coronavirus infection (buildings and entire complexes are being built and repurposed to combat it), and, on the other hand, especially for "traditional" diseases, the trend outlined in previous years continues.
Problems of improving the mechanism of regulation and liberalization of the financial market in the conditions of Turkmenistan's accession to the WTO
Authors: Habyyeva Aysoltan
Published: June 2022

The purpose of the study is to develop proposals for the liberalization of the financial services sector of the economy of Turkmenistan in the context of the country's potential accession to the World Trade Organization. The article considers the problems and challenges that Turkmenistan may face in the process of negotiations on the terms of accession to the WTO. The scientific novelty lies in the theoretical justification of the expediency of maintaining the status quo in trade in financial services in the short and medium term within the initial list of specific obligations of the country provided for by the GATS. As a result, in the conditions of macroeconomy and its transitional nature, taking into account the unpredictable volatility of hydrocarbon prices, it is recommended to leave the existing restrictions on access to the financial services market and on the national regime unchanged in the context of a gradual process of lifting restrictions on the movement of capital and its complete liberalization.
To The Question About The Way Out Of The Crisis In Education: Back To Kant!
Authors: Jenei Terez , Kiss Lajos Andras , Shachina Anna Yrievna
Published: June 2022

The authors of the article are trying to identify the signs of a crisis of our time as a consequence of the refusal from the philosophical justification of the goals and objectives of scientific pedagogy, which as a chain reaction entail ignoring the results of sciences related to pedagogy: neurobiology and psychology. The reproductive approach in education selectively takes into account the results of the empirical sciences, as they serve to justify it. The result is a shift in emphasis: being driven by the hypothetical imperatives of competitiveness in the labor market, teachers and other adults feel the need for the achievements of the pupils, for their effectiveness. As a consequence, the child's psyche does not develop properly which manifests itself in the inability to see the subjects of interaction in the vis-a-vis, in an effort to objectify what is not subject to objectification - a person. The authors of the article see the solution to the problem in the appeal in the philosophical and pedagogical system of I. Kant, that may be reconstructed from his works. The authors of the article conclude that I. Kant may rightfully be considered the founder of a productive approach to education.
On the question of the ontological and epistemological status of emergent phenomena
Authors: Chukin Sergey Georgievitch
Published: June 2022

A significant increase in scientific discoveries, made possible, among other things, thanks to the computing power provided by modern information technologies, occurs against the background of the lack of theoretical and methodological resources necessary for their scientific conceptualization. The situation is similar to the one that took place at the turn of the 19th and 20th centuries and became the object of reflection on the part of philosophers called emergentists. This explains the revival in our time of interest in some of their ideas, including the idea of ontological novelty, which emergent phenomena possess. Modern emergentism is positioned as a realistic teaching that aims to find access to reality in itself, before any knowledge about it, which implies overcoming the correlationism that has dominated philosophy since the time of Kant. One of the representatives of modern emergentism, Manuel DeLanda, tries to combine the position on the ontological novelty of emergent objects with the concept of individuation by Georges Kangilem, which reveals the mechanism of their occurrence and concretization in the form of individual singularities. This requires abandoning the ontology inherited from the ancient Greeks, based on the dialectic of the general and the singular, in favor of an ontology based on individual and universal singularities. The article analyzes the arguments of the supporters of the "new ontology" and concludes that, as in the case of classical emergence, modern discussions are caused by a crisis in physics, which is faced with the fact that the facts recorded during the study of the microcosm are inexplicable from the point of view of the existing theory, and therefore are really ontologically new. But it is possible that with the creation of the" new physics", these facts will cease to be emergent and will pass into the category of "others".

Authors: Ahmed Mosher R.
Published: June 2022

In order to characterize ground water quality in Zaweta district / Dohuk governorate, eight wells are selected to represent their water quality. Monthly samples are collected from the wells for the period from October 2005 to April 2006. The samples are tested for conductivity, total dissolved solids, pH, total hardness, chloride, alkalinity and nitrate according to the standard methods. The results of statistical analysis showed significant difference among the wells water quality in the measured parameters. Ground water quality of Zaweta district has high dissolved ions due to the nature of studied area rocks. Total dissolved solids of more than 1000 mg/l made the wells Gre-Qassroka, Kora and Swaratoka need to be treated to make taste palatable. Additionally high electrical conductivity and TDS made Zaweta ground water have a slight to moderate restriction to crop growth. The high alkalinity of Zaweta ground water indicated stabilized pH. The water quality of all the wells is found excessively hard. The nitrate concentration of Zaweta ground water ranged between 0.19-42.4 mg/l below the guidelines for WHO and the maximum nitrate concentration is recorded in Kora well.

Authors: Abdulla Thaer A.
Published: June 2022

HYSYS process simulator is used for the analysis of existing HF stripping column in LAB plant (Arab Detergent Company, Baiji-Iraq). Simulated column performance and profiles curves are constructed. The variables considered are the thermodynamic model option, bottom temperature, feed temperature, and column profiles for the temperature, vapor flow rate, liquid flow rate and composition. The five thermodynamic models options used (Margules, UNIQUAC, van laar, Antoine, and Zudkevitch-Joffee), affecting the results within (0.1-58%) variation for the most cases. The simulated results show that about 4% of paraffin (C10 & C11) presents at the top stream, which may cause a problem in the LAB production plant. The major variations were noticed for the total top vapor flow rate with bottom temperature and with feed composition. The column profiles maintain fairly constants from tray 5 to tray 18. The study gives evidence about a successful simulation with HYSYS because the results correspond with the real plant operation data.

This paper investigates the dynamic relationship between exchange rate, interest rate and stock market of Indonesia from 2008 to 2017. We estimate long memory and asymmetric volatility in dynamic correlations between these variables using the VAR, FIAPARCH and DCC approach. This study estimates the emergence of long memory and asymmetric volatility in the dynamic relationship between these variables using the VAR and FIGARCH methods. The results showed that there was a strong indication of long memory and asymmetric volatility in all the volatility of the observed data. Asymmetric volatility for unexpected news in Negative results for the foreign exchange and bond markets. Positive shocks for foreign exchange and bond markets will trigger negative sentiment. In addition, the dynamic relationship between the bond market and the stock market is always found to be in a negative correlation. Positive results were obtained on bonds and exchange rates which were the same findings as in other developing countries. While the JCI showed positive results, volatility was more influenced by negative shocks than positive shocks for the stock market. Volatility shift in stock return is estimated using multiple breakpoints. The shift in volatility upwards externally was not caused by Indonesia's global political-economic financial condition. The finding from the analysis of the volatility model is that the presence of shocks in volatility causes abrupt changes in dynamic relationships whose effects are only in the short term.
Problem ogólnych pojęć abstrakcyjnych w kontekście językoznawstwa kognitywnego
Authors: Fornal Marzena
Published: June 2022

Obecnie panuje powszechne przekonanie, że założenia pierwszego kognitywizmu w językoznawstwie po- winny być całkowicie zastąpione przez paradygmat ucieleśnienia. Jednak choć panuje powszechna zgoda, że kwestia ugruntowania pojęć konkretnych jest dobrze wyjaśniona w ramach teorii ucieleśnionego języka (Lakoff, Johnson), pojawia się poważny problem w przypadku prób wyjaśnienia mechanizmu wyłaniania się pojęć abstrakcyjnych (ang. ungrounding problem, Dove). W niniejszym artykule staram się wykazać, że prawdziwym problemem, przed jakim stoją teorie ucieleśnienia, nie jest to, w jaki sposób myślenie abstrakcyjne jest ucieleśnione (Lakoff, Barsalou), lecz jak ucieleśnione poznanie może stać się abstrakcyjne. Jest to tak zwany ungrounding problem, który rozbija się na trzy pomniejsze kwestie: problem generalizacji, problem elastyczności oraz problem od-cieleśnienia. Jak twierdzę, dopiero przyjęcie stanowiska pośredniego pomiędzy teoriami ucieleśnienia a teoriami dystrybutywnymi pozwoli na sformułowanie satysfakcjonującego rozwiązania. Poniższy artykuł stanowi przybliżenie jednego z takich stanowisk pośrednich, jakim jest teoria ucieleśnionego i od-cieleśnionego poznania Guya Dove’a.

Рабочие особи, выращенные на сотах с углом основания дна в 110º обладают высокой потенцией к секреции личиночного молочка, и особенно при стимулирующих подкормках с белковыми наполнителями. Данное обстоятельство особенно выгодно при формировании семей-воспитательниц используемых для вывода пчелиных маток. Наличие молочка в гнезде с открытым расплодом, надежный признак рефлекса выращивания расплода. По результатам опытов содержание личиночного молочка в ячейках сота, с углом основания дна в 110º при стимулирующей подкормке углеводным кормом, содержащим белковый препарат «Овогид» было больше, чем в контрольной группе, на 5,69 мг, а с «Микровитам» – на 7,5 мг, с углом в 120 º он был больше на 2,3 мг и 3,4 мг соответственно. При выкармливании личинок летней генерации данный параметр был больше, по сравнению с контрольной группой, соответственно на 2,23 и 1,26 мг, у осенней генерации – на 3,36 и 3,14 мг.

Working individuals reared on combs with a bottom angle of 110º have a high potency for the secretion of larval milk, and especially when stimulating top dressing with protein fillers. This circumstance is especially beneficial in the formation of host families used for the breeding of queen bees. The presence of milk in an open brood nest is a reliable indicator of the brood rearing reflex. According to the results of the experiments, the content of larval milk in the cells of the honeycomb, with a bottom base angle of 110º, with stimulating feeding with carbohydrate food containing the protein preparation «Ovogid» was 5.69 mg more than in the control group, and with «Microvitam» – by 7 .5 mg, with an angle of 120 º it was 2.3 mg and 3.4 mg more, respectively. When feeding the larvae of the summer generation, this parameter was higher, compared with the control group, by 2.23 and 1.26 mg, respectively, in the autumn generation, by 3.36 and 3.14 mg.

Published: June 2022

В настоящее время в гусеводстве особенно распространенными являются кандидамикозы пищеварительного тракта. В настоящем сообщении приводятся результаты механизма размножения и активного заселения основных отделов пищеварительного тракта гусей Candida albicans и, как следствие, затормаживания активности нормофлоры Lactobacillus spp. и Bifidobacterium spp. Установлено, что применение ферментного препарата литиказы с адаптогенами (пробиотиком и прополисом) на фоне кандидамикоза пищеварительного тракта способствовало восстановлению функционально детерминированных нарушений микробиоценоза в зобе, мышечном и железистом отделах желудка, тонком и толстом отделах кишечника. Это доказывает, что восстановления барьерной функции пищеварительного тракта связано с активизацией нормофлоры Lactobacillus spp и Bifidobacterium spp.

Currently, candidiasis of the digestive tract is especially common in goose breeding. Currently, processes of reproduction and activation of the colonization of the main sections of the digestive tract of geese Candida albicans are taking place and, as a result, inhibition of the activity of the normoflora of Lactobacillus spp. and Bifidobacterium spp. It was established that the use of the enzyme preparation lyticase with adaptogens (probiotic and propolis) against the background of candidiasis of the digestive tract contributed to the restoration of functionally determined microbiocenosis disorders in the goiter, muscular and glandular sections of the stomach, small and large intestines. This proves that the restoration of the barrier function of the digestive tract is associated with the activation of the normoflora of Lactobacillus spp and Bifidobacterium spp.

Tandem rigidification and π-extension as a key tool for the development of a narrow linewidth yellow hyperfluorescent OLED system.
Authors: Bartkowski Krzysztof , Zimmermann Crocomo Paola , Kochman Michał , Kumar Dharmendra , Kubas Adam , Data Przemysław , Lindner Marcin
Published: June 2022

Hyperfluorescence (HF), a relatively new phenomenon utilizing excitons transfer between two luminophores, requires careful pairwise tuning of molecular energy levels and is proposed to be the crucial step toward the development of new, highly effective OLED systems. To date, barely a few HF yellow emitters with desired narrowband emission but moderate external quantum efficiency (EQE <20%) have been reported. This is because a systematic strategy embracing both Förster Resonance Energy Transfer (FRET) and triplet to singlet (TTS) transition as complementary mechanisms for effective excitons transfer has not yet been proposed. Herein, we present a rational approach, which allows to through subtle structural modification, a pair of compounds built from the same donor and acceptor subunits, but with varied communication between these ambipolar fragments, to be obtained. The TADF-active dopant is based on a naphthalimide scaffold linked to the nitrogen of a carbazole moiety, which through the introduction of an additional bond leads not only to π-cloud enlargement but also rigidifies and inhibits rotation of the donor. This structural change prevents TADF, and allows to guide bandgaps and excited states energies to simultaneously pursue FRET and TTS process. New OLED devices utilizing the presented emitters show excellent external quantum efficiency (up to 27%) and narrow full width at half maximum (40nm), which is a consequence of very good alignment of energy levels. The presented design principles prove that only a minor structural modification is needed to obtain commercially applicable dyes for HF OLED devices.
Diagnosis and treatment of chronic subdural hematomas in elderly and senile age patients (own experience and current global trends)
Authors: Borovyk L.R.
Published: June 2022

Objective ‒ to improve the treatment of chronic subdural hematoma (CSDH) in older people.Materials and methods. Retrospective analysis of the results of diagnosis and treatment of patients with CSDH treated in the Department of Neurotrauma of Romodanov Institute of Neurosurgery NAMS of Ukraine and Zaporizhzhya City Hospital for Emergency and Emergency Medicine in 2010–2019 was performed. The distribution by age was as follows: elderly patients – 80, patients senile age – 32, long-lived – 6. Multislice computed tomography was made in 86.7 % of patients, magnetic resonance imaging ‒ in 13.3 %. In 118 cases different types and volumes of surgical intervention were performed, in 58 ‒ conservative treatment.Results. The indication for surgery in elderly and senile patients with CSDH is the presence of hematoma ≥100 cm3 in the absence of dislocation syndrome. Concomitant somatic diseases were revealed in 95 % of cases. Treatment efficacy was monitored by dynamic magnetic resonance imaging studies (in 73.5 % cases) and multislice computed tomography (in 26.5 %). A comprehensive clinical and neurological examination was performed according to the modified Rankine scale, the Glasgow extended consequences scale, calculation of the Barthel index, after 1, 3 and 6 months. Postoperative complications: CSDH recurrence in 10 (6.0%) patients, mostly older than 60 years, pneumocephalus ‒ in 1 (0.84 %), meningoencephalitis ‒ in 1 (0.84 %) patients. Postoperative mortality was 6.8 % (8 cases). Conclusions. When choosing a method of treatment should be considered etiopathogenetic factors of hematoma formation, the severity of neuroimaging characteristics of CSDH, the degree of displacement of midline structures and neurological symptoms, somatic risks and the patient’s consent. The choice of treatment tactics for the elderly and senile is based not only on the Glasgow consequences scale and Markwalder grading score, but also on the scale of A.K. Thotakura et al. (Displacement of median structures and hematoma density (on the Hounsfield scale)). Removal of the hematoma is the main method of treating CSDH, aspiration of CSDH through burr holes followed by passive drainage is the method of choice. Conservative treatment of CSDH according to clear indications can be used both alone and in combination with surgical treatment.

Mathematics learning will achieve satisfactory results if it can meet all standards in the learning process, including mathematical communication skills. Mathematical communication is an ability to understand problems by modeling them into mathematical symbols and explaining mathematical ideas in writing or orally. This research with descriptive qualitative method aims to describe the mathematical communication skills of students with high and moderate mathematical abilities in class X in solving SPLTV questions. The data collection technique used a written test in the form of SPLTV material story questions and interviews as supporting data. The results showed that students who had high mathematical ability fulfilled all indicators of mathematical communication correctly, while students who had moderate mathematical ability met the indicators of mathematical communication in understanding the core of the problem and mentioning what is known and asked in the question. It is hoped that the teacher will be able to improve students' mathematical communication skills by applying story questions whose answers have mathematical communication indicators so that students are increasingly able to express mathematical ideas both in writing and verbally and are able to fulfill all indicators of mathematical communication.

Kualitas pendidikan Indonesia masih tergolong rendah, salah satu faktornya yakni rendahnya kemampuan literasi matematis. Hal tersebut dibuktikan berdasarkan studi PISA tahun 2018 bahwa negara Indonesia mengalami penurunan peringkat dengan perolehan skor di bawah rata-rata. Untuk mengatasi hal tersebut, alternatif yang perlu dilakukan yakni dengan menerapkan etnomatematika dalam pembelajaran matematika. Penelitian ini bertujuan untuk mendeskripsikan literasi matematis budaya Jombangan dalam perspektif etnomatematika. Jenis penelitian ini yaitu penelitian kualitatif dengan pendekatan etnografi. Pengumpulan data dilakukan dengan observasi partisipan dan wawancara. Untuk instrumen utama dalam penelitian ini yaitu peneliti sendiri, sedangkan instrumen pendukungnya berupa pedoman observasi, pedoman wawancara, dan lembar catatan penelitian. Teknik analisis data menggunakan analisis domain dan analisis taksonomi. Hasil dari penelitian ini menunjukkan bahwa berdasarkan kajian etnomatematika pada budaya Jombangan khususnya Candi Rimbi, pengrajin manik-manik, dan batik Jombangan ditemukan beberapa konsep matematika yang di antaranya adalah satuan baku dan tidak baku, konsep panjang, perbandingan, transformasi geometri, simetri, dan bangun datar. Berdasarkan kajian tersebut, aktivitas yang dilakukan oleh masyarakat Jombang memenuhi beberapa aspek dari literasi matematis yakni aspek konten, proses, dan konteks.

Kemampuan berargumen merupakan salah satu hal penting untuk dimiliki siswa karena dapat mengukur pemahaman siswa. Dalam hal pembelajaran matematika, siswa yang menyampaikan argumen matematika dibutuhkan untuk mengembangkan kemampuan matematika dan memahami konsep matematika siswa. Salah satu studi untuk mengidentifikasi serta menilai kualitas argumen matematika siswa ialah Toulmin Argumentation Pattern. Tujuan penelitian ini yaitu untuk menganalisis argumen matematika siswa SMA ditinjau dari gaya kognitif visualizer-verbalizer dengan menggunakan teori argumen Toulmin. Jenis penelitian ini yaitu deskriptif dengan pendekatan kualitatif. Subjek penelitian terdiri dari 4 orang siswa kelas XI SMA dengan komposisi 2 siswa bergaya kognitif visualizer dan 2 siswa lainnya bergaya kognitif verbalizer. Instrumen yang digunakan ialah tes gaya kognitif, tes argumen matematika dan pedoman wawancara. Data yang diperoleh dari tes argumen matematika akan di analisis berdasarkan teori argumen Toulmin dimana terdiri atas 6 komponen yaitu data, claim, warrant, backing, qualifier, dan rebuttal. Hasil penelitian menunjukkan bahwa siswa bergaya kognitif visualizer dan verbalizer mampu menunjukkan semua komponen argumen pada soal tes argumen matematika nomor 1 dan tidak berhasil menunjukkan rebuttal pada soal tes argumen matematika nomor 2. Siswa bergaya kognitif visualizer menunjukkan warrant bertipe induktif. Sedangkan siswa bergaya kognitif verbalizer mampu menunjukkan warrant bertipe induktif, structural-intuitif dan deduktif. Dalam menyusun argumennya, siswa bergaya kognitif visualizer menunjukkan lebih sering menggunakan simbol-simbol dengan bahasa yang singkat tapi langsung ke tujuan. Berbeda dengan siswa bergaya kognitif verbalizer yang lebih bermain dengan kata-kata dan mampu memberikan kesimpulan akhir dengan jelas dan rinci dengan bahasa yang mudah dipahami.

Penelitian ini bertujuan untuk mendeskripsikan literasi matematika siswa kelas IX SMP di Sidoarjo dalam menyelesaikan soal Higher Order Thinking Skills (HOTS) pada topik proporsi. Penelitian ini termasuk penelitian deskriptif kualitatif dengan menggunakan metode tes tulis terkait soal HOTS proporsi dan wawancara. Data yang diperoleh dianalisis menggunakan indikator literasi matematika sesuai pada Kerangka Kerja PISA 2021 pada tahap merumuskan (formulate), menerapkan (employ), serta menafsirkan dan mengevaluasi (interpret and evaluate). Subjek penelitian dipilih menggunakan teknik purposive sampling. Dari 12 siswa dengan kemampuan matematis tinggi, tiga siswa dengan literasi matematika yang berbeda dipilih sebagai subjek pada penelitian ini. Hasil penelitian menunjukkan bahwa dalam menyelesaikan soal HOTS proporsi, pada tahap merumuskan (formulate), siswa kurang mampu merepresentasikan situasi matematis menggunakan model matematika yang sesuai dengan topik proporsi. Pada tahap menerapkan (employ), siswa mampu menggunakan konsep dan prosedur matematis untuk menyelesaikan soal HOTS proporsi. Sedangkan, pada tahap menafsirkan dan mengevaluasi (interpret and evaluate), siswa kurang mampu menafsirkan hasil matematis kembali ke konteks dunia nyata. Sehingga, diperlukan pembelajaran yang bukan hanya melatih siswa untuk menerapkan konsep dan prosedur matematis untuk menyelesaikan soal, namun juga dapat melatih siswa untuk merepresentasikan situasi matematis dalam konteks dunia nyata menjadi model matematika dan menafsirkan solusi matematis yang telah diperoleh kembali ke konteks dunia nyata.

Kata Kunci : Literasi matematika, Soal HOTS, Proporsi
