ROUSSEAU’NUN AYDINLANMACI AKIL ELEŞTİRİSİ
Authors: DURHAN Gülümser 
Published: March 2023

Aydınlanma Dönemi düşünürü olan Jean-Jacques Rousseau, kendi döneminin düşünce anlayışına karşı olan negatif tutumuyla, aydınlanmaya, kendi döneminin filozoflarına, düşünce zincirine karşı olan ağır eleştirileriyle karşımıza çıkmaktadır. Aydınlanmayla birlikte, doğal halde bulunan insanın bozulduğuna, yozlaştığına, duygularını göz ardı etti-ğine, tutsaklığına bilim sanat veya eğitim gibi kurumlarının etkisi nedeniyle kendine ya-bancılaştığına vurgu yapan Rousseau, bu tutum ve sert eleştiriyle dönemin aykırı sesi olarak dikkat çekmektedir.
Aklın ön plana çıktığı aydınlanma dönemi, aklını dayanak alan, kendi akıl gücünün far-kındalığına varan, kendi davranışlarının sorumluluğunu üstelenen, başkasının kendisini yönlendirmesine olanak tanımayan ve aklını kiraya vermemiş bir insan modelini salık vermektedir. İnsanın hayatına anlam katan ve yapıp etmelerini düzene koyan evrensel bir akıl gücüdür. Eğer insan aklı, bağıl düşüncelerden, bağnazlıktan, makul veya mantıklı temeli olmayan gelenek görenek, töre gibi örf ve adetlerden kurtulursa o insanın kendisi de kurtuluşa ermiş demektir. Dolayısıyla aydınlanma düşüncesinde akıl, insanı düşmüş oldu-ğu kötü durumlardan kurtaracak, hata yapmasını engelleyecek temel bir yol göstericidir.
Rousseau’ya göre böylesi bir insan anlayışı öne sürmek, insanın bencilleşmesine, doğal haldeki insanın bozulmasına, insanın tabiatı gereği olan yapısına yabancılaşmasına se-bebiyet vermektedir. Bu durumda yabancılaşan insanın yapıp etmelerinde ve hayatında bozulmalar olmaktadır. Zira böyle bir durumda özgürlük ortadan kalkmış ve eşitsizlikler doğmuştur. Bu şekildeki bir toplumda mülkiyet fikri ve iş bölümü ayrımı gibi hususlar da ortaya çıkmıştır. Tüm bu sebeplerin esas temeli, duygulardan ziyade akla verilen önemden kaynaklanmaktadır. Bu sebeple Rousseau, aklın yüceltilmesi ve duyguların bir kenara bırakılmasıyla insanın özünden kopuş yaşadığını savunmakta ve aydınlanmayı; özelinde aklı eleştirmektedir. Dolayısıyla çalışmamızın amacı, Rousseau’nun insan aklına olan insani ve toplumsal boyuttaki olumsuz tavrına dikkat çekmektir.

Миграционные ориентации старших школьников при переходе к получению профессионального образования
Authors: Логинов Д.М. , Семионова Е.А. 
Published: March 2023

В статье рассматриваются варианты ориентации домохозяйств, в которых имеются старшие школьники, на миграцию в другие регионы России при переходе к профессиональному образованию. На основе данных специального анкетного опроса выявлено, что установки на образовательную миграцию детей охватывают около половины семей. Результаты исследования иллюстрируют значительную дифференциацию установок на территориальную мобильность молодежи по поселенческим типам проживания, условиям жизнедеятельности и образовательным притязаниям. Выявлен и конкретизирован мотивационный спектр формирующихся миграционных установок. Показано, что образовательная миграция рассматривается большинством домохозяйств как первый этап окончательного перемещения ребенка в населенный пункт с субъективно более благоприятными условиями жизни и выстраивания трудовой карьеры, что расширяет возможности формирования человеческого капитала молодежи, но также объективизирует «вымывание» ресурсов из малых населенных пунктов.
THE INFLUENCE OF MODERN INNOVATIVE TECHNOLOGIES ON THE MOTOR ACTIVITY OF STUDENTS
Authors: Salamakha O. , Chekhovska A. 
Published: March 2023

The article reveals the features of using modern innovative technologies to increase the motor activity of students. Modern methods for determining the optimal level of motor activity for people of different age categories were analyzed. Methods of increasing motor activity using modern innovative technologies have been determined. The article describes the characteristics and features of the use of innovative educational technologies in the physical education of students. In the scientific work, the organizational and methodical features of the use of interactive teaching methods to increase the level of motor activity are given. Modern forms of activity organization in the system of extracurricular activities are revealed. Overcoming passivity involves: a certain consistency in changing negative instructions and creating new behavior; a pedagogically justified complex of educational influences aimed at changing the negative behavior of a student and at changing the negative stereotype of his behavior. Overcoming the negative attitude to motor activity involves changing the ratio of effective - practical and educational functions in education.
The main manifestation of a passive attitude to physical culture in most cases is the absence of students from classes without a good reason, and sometimes there is a certificate from a doctor. In modern scientific and methodical works, the issue of measurement and assessment of the mode of motor activity is considered quite widely, the daily and weekly volumes of motor activity of persons of different ages and physical condition are investigated using the Framingham method; regularities and interrelationships of motor activity and physical condition were studied.
Physical education and sports as a means of increase the level of motivation to the defense capacity of the state
Authors: Galan Y. 
Published: March 2023

Numerous studies prove the fact that in the modern world, it is possible to ensure the state's defence capability only through cooperation with various fields, including physical education and sports. One of the important aspects of ensuring a reliable degree of the state's national security is its own combat-ready armed forces, which should include persons with an appropriate level of physical training and health condition. Currently, taking into account the break out of the COVID-19 pandemic, an insufficient level of physical activity is observed among young children, which poses a serious problem and a threat to modern society and its defence capability in the future. Scientific substantiation of pedagogical conditions, namely methods and means aimed at ensuring the effective development of schoolchildren's motor qualities, and their attitude to physical culture and sports is one of the most important and promising tasks aimed at improving the defence system of Ukraine. The future of the state depends on the current generation. The state's defence capability is the ability to defend itself in case of armed aggression or armed conflict, which is why physical culture and sports play a decisive role in this process. Various studies provide evidence that the foundation that affects a country's defence capability is laid in childhood.
The relevance of the mentioned issue lies in the formation and selection of the main pedagogical conditions for the popularization of physical education and sports as a means of the defence capability of the state and the protection of its sovereignty. Pedagogical conditions are a category defined as a system of certain forms, methods, means, material conditions, and real situations that are objectively developed or subjectively created, necessary to achieve a specific pedagogical goal.
One of the universal and most effective means of defence capability is physical activity, a healthy lifestyle, physical culture and sports, which enable us to raise healthy and strong defenders. The level of Ukraine's defence capability in the future depends on the extent to which schoolchildren will be involved in motor activity, a healthy lifestyle, and physical education and sports.

The article presents various aspects of the planning of the educational and training process in sports swimming, reveals the peculiarities of planning at various stages of multi-year sports training, in particular, long-term, annual and operational, as well as the general structure of the training of athletes-swimmers and the peculiarities of building macro-, meso- and microcycles of various types.
In addition, the historical aspects of the formation and development of the process of planning long-term sports training, as a pedagogical system are analyzed, which aims to ensure consistent performance of training tasks by swimmers, using various means, methods and organizational forms and is a particularly important factor for building a successful sports career.
It has been established that the planning of the educational and training process in sports swimming is extremely important, which makes it possible, to a certain extent, to predict the conditions of training, to determine effective means and methods for solving certain tasks faced by swimmers in order to achieve expected sports results. A properly planned process of sports training will help the coach and the swimmer to determine specific tasks for mastering technical and tactical skills, special physical, moral and psychological qualities. Training then was quite chaotic, as the planning of training programs, physical and technical training of athletes developed mainly in an unsystematic manner.

OBJECTIVES: Early diagnosis of triple-negative (TN) and human epidermal growth factor receptor 2 positive (HER2+) breast cancer is important due to its increased risk of micrometastatic spread necessitating early treatment and for guiding targeted therapies. This study aimed to evaluate the diagnostic performance of machine learning (ML) classification of newly diagnosed breast masses into TN versus non-TN (NTN) and HER2+ versus HER2 negative (HER2−) breast cancer, using radiomic features extracted from grayscale ultrasound (US) b-mode images. MATERIALS AND METHODS: A retrospective chart review identified 88 female patients who underwent diagnostic breast US imaging, had confirmation of invasive malignancy on pathology and receptor status determined on immunohistochemistry available. The patients were classified as TN, NTN, HER2+ or HER2− for ground-truth labelling. For image analysis, breast masses were manually segmented by a breast radiologist. Radiomic features were extracted per image and used for predictive modelling. Supervised ML classifiers included: logistic regression, k-nearest neighbour, and Naïve Bayes. Classification performance measures were calculated on an independent (unseen) test set. The area under the receiver operating characteristic curve (AUC), sensitivity (%), and specificity (%) were reported for each classifier. RESULTS: The logistic regression classifier demonstrated the highest AUC: 0.824 (sensitivity: 81.8%, specificity: 74.2%) for the TN sub-group and 0.778 (sensitivity: 71.4%, specificity: 71.6%) for the HER2 sub-group. CONCLUSION: ML classifiers demonstrate high diagnostic accuracy in classifying TN versus NTN and HER2+ versus HER2− breast cancers using US images. Identification of more aggressive breast cancer subtypes early in the diagnostic process could help achieve better prognoses by prioritizing clinical referral and prompting adequate early treatment.

BACKGROUND: Multiple lines of evidence suggest that single nucleotide polymorphisms (SNPs) in genes encoding components of the microRNA processing machinery may underlie susceptibility to various human diseases, including cancer. OBJECTIVE: The present study aimed to investigate whether rs6877842, rs642321 and rs10719 SNPs of DROSHA, a key component of the miRNA biogenesis pathway, are associated with increased risk of breast cancer. METHODS: A total of 100 patients diagnosed with breast cancer and 100 healthy women were included. Following extraction of DNA, genotyping was performed by tetra primer- amplification refractory mutation system-PCR (T-ARMS-PCR) technique. Under the co-dominant, dominant and recessive inheritance models, the association between DROSHA SNPs and breast cancer risk was determined by logistic regression analysis. The association of DROSHA SNPs with patients’ clinicopathological parameters was assessed. Also, haplotype analysis was performed to evaluate the combined effect of DROSHA SNPs on breast cancer risk. RESULTS: We observed a statistically significant association between DROSHA rs642321 polymorphism and breast cancer susceptibility (P < 0.05). Under the dominant inheritance model, DROSHA rs642321 polymorphism was significantly associated with increased risk of breast cancer (OR: 6.091; 95% CI: 3.291–11.26; P = 0.0001). Our findings demonstrated that DROSHA rs642321 T allele can contribute to the development of breast cancer (OR: 3.125; 95% CI: 1.984–4.923; P = 0.0001). We also found that GTC and GTT haplotypes conferred significant risk for breast cancer (OR: 2.367; 95% CI: 1.453–3.856; P = 0.0001 and OR: 7.944; 95% CI: 2.073–30.43; P = 0.0001, respectively). CONCLUSIONS: These results provide the first evidence that DROSHA rs642321 polymorphism is associated with increased risk of breast cancer. However, further studies are needed to firmly validate these findings.

Published: March 2023

Introduction. Approaches to the introduction of negative feedback in pulse control systems regulating the parameters of electricity flow with pulse-width modulation (PWM) continue to attract research attention in the field of switch power amplifiers (SPA) and switch voltage converters (SVC). Evaluation of the potential of compensation methods is of importance when selecting power electronics devices for various purposes.Aim. To review compensation methods for parameter regulation and to investigate conditions for the operational stability of SVC with feedback on output voltage and current.Materials and methods. The research methodology included the theory of pulsed automatic control systems, the method of harmonic linearization with stability assessment according to Nyquist criteria, and the generating filter method based on multiple frequencies.Results. An analysis of operational stability conditions was carried out. Analytical dependences and graphical representation of the limit feedback values from the modulation parameters and the switch transformation scheme were proposed.Conclusion. The conducted study of the feedback depth in SVC, limited by the penetration of high-frequency components into the path of a width-modulated signal and its delay, due to the peculiarities of the terminal stage of the SPA, demonstrates that the limit value of the voltage feedback depth at typical circuit parameters does not exceed 12 dB, while the depth of the current feedback of the filter choke of the low frequencies can be fundamentally (more than 20 dB) higher. At the same time, the implementation of voltage stabilization and output current limitation modes for maintaining reliable operation in start-up and overload modes is possible only with the use of combined feedback.

Authors: Vagin A. V. , Vorotyntseva A. S. 
Published: March 2023

Introduction. Acoustic profiling is a conventional method for studying the geological structure of the seabed. To this end, a low-frequency acoustic profiler with an operating frequency range of 1…14 kHz can be used. However, under lower operating frequencies, the difficulty of achieving the required resolution arises. The problem of improving the angular resolution of a hydroacoustic device, particularly in the direction of the carrier movement, remains to be a priority task in the search and detection of objects on the seabed, as well as the study of the bottom soil structure. Angular resolution can be improved through several approaches, including an algorithm for synthesizing the antenna aperture based on the law of the phase change of the reflected signal. This approach is relevant in the design of highresolution hydroacoustic tools.Aim. To demonstrate the possibility of constructing a bottom soil profiling device, as well as the possibility of increasing its angular resolution based on an algorithm for synthesizing the antenna aperture of an acoustic profiler.Materials and methods. The study employed the groundwork data obtained for side-scan sonars with a synthetic aperture in terms of constructing an antenna device and the methods of radio-wave excitation developed for radar systems.Results. The possibility of synthesizing the antenna aperture for an acoustic profiler of the bottom soil was studied. An algorithm for synthesizing the antenna aperture was investigated along with phase distortions of the trajectory signal and their influence on the sonar image. The fundamental principles of processing the trajectory signal were considered.Conclusion. An approach to increasing the resolution of an acoustic profiler when performing search and survey tasks is proposed. The proposed design of the acoustic part of a profiling device can be used in the development of search and survey hydroacoustic devices with a high angular resolution.
