Determining that miRNAs play a role in breast cancer pathogenesis suggests that it may be useful in the diagnosis and treatment of breast cancer. In this study, 39 patients with invasive breast cancer were diagnosed with serum levels of 20 miRNAs(miR-105, miR-21, miR-141, miR-200a, miR-200b, miR-200c, miR-203, miR-210, miR-375, miR-34a, miR-133a, miR-155, miR-139-5p, miR-143, miR-145, miR-365, miR-299-5p, miR-411, miR-452, miR-17) were analyzed during diagnosis and after treatment. In the analysis results, it is detected that serum levels of miR-200c(p=0.030), miR-375(p=0.045), miR-34a(p=0.042) were significantly higher in the local advanced/metastatic group. Serum level of miR-141(p=0.062) was lower in patients with positive lymph node involvement, whereas miR-133a(p=0.037) levels were higher in the same patient group. MiR-105(p=0.015), miR-203(p=0.015), miR-375(p=0.033), miR-145(p=0.025) serum levels were significantly higher in the progesterone receptor negative group, likewise miR-105(p=0.053) levels were high in the estrogen receptor negative patient group. The high levels of miR-375 and miR-133a were noticeable in human epidermal growth factor receptor-2 positive patients(p=0.037 and p=0.014, respectively). MiR-143(p=0.009) and miR-145(p=0.017) levels were observed to be higher in the patient group with a ki-67 index>20%. It was found that 2 miRNAs(miR-133a(p=0.018) and miR-139-5p(p=0.004)) were significantly higher in patients in the luminal B group, which were separated by molecular subgroups. Nine of miRNAs that evaluated(miR-105(p=0.0001), miR-21(p=0.001), miR-141(p=0.041), miR-200a(p=0.003), miR-200b(p=0.0001), miR-200c(p=0.0001), miR-203(p=0.0001), miR-34a(p=0.0001), miR-452(p=0.018)) significantly increased after treatment and 5 of the miRNAs(miR-155(p=0.0001), miR-143(p=0.0001), miR-145(p=0.0001), miR-365(p=0.0001), miR-299-5p(p=0.0001)) were significantly reduced after treatment. We think that miRNAs may help in evaluating the follow-up and prognosis of invasive breast cancer.

The study shows how insecure attachment types (anxious and avoidant) are associated with traits of the "dark triad" (narcissism, psychopathy and Machiavellianism) in a sample of patients with borderline personality disorder. It was found that among the respondents, the greatest relationship was found in individuals with a predominance of the anxious type of attachment, who showed a statistically significant sharpening of such traits as: impulsiveness, manipulativeness, lack of sympathy and empathy ("psychopathy"). And weakly expressed, relative to the sample, traits of demonstrativeness, egocentrism, inflated self-esteem (“narcissism”) and “Machiavellian” traits: a weak focus on moral standards, fixation on personal gain. There were no reliable data on the relationship between the avoidant type and dark triad traits in the course of the study, however, avoidant and anxious types are significantly correlated with low levels of psychological well-being among patients with borderline personality disorder.

Published: March 2023

Gaps in communication training have been identified in Canadian and international academic and practicum dietetics programs. A workshop was developed to pilot supplementary media training to nutrition students/trainees studying in Nova Scotia. Students, interns, and faculty from two universities participated in the workshop. Data on perceived learning, media knowledge/skill use, and workshop feedback were collected immediately post-workshop using a mixed-form questionnaire. A modified questionnaire was administered eight months post-workshop to obtain information on utility of the perceived acquired knowledge/skills. Closed-ended responses underwent descriptive analysis, while open-ended responses underwent thematic analysis. Twenty-eight participants completed the questionnaire post-workshop, and six completed it at follow-up. All participants rated the workshop positively (7-point Likert scale) and reported learning something new (perceived). Perceived learning emphasized general media knowledge/skills and communication skills. Follow-up data suggested participants had applied perceived media knowledge/skills in message development and media and job interviews. These data suggest that nutrition students/trainees may benefit from supplementary communications and media training and provide a stimulus for ongoing curriculum review and discussion.

Banyak penyelesaian perkara kekerasan dalam rumah tangga yang tidak memenuhi rasa keadilan, terutama bagi korban dan subordinat dalam rumah tangga. Dalam jurnal ini disampaikan hasil yaitu pertama, penyelesaian perkara kekerasan dalam rumah tangga pada kenyataannya diselesaikan melalui Undang-Undang Nomor 23 Tahun 2004 tentang penghapusan kekerasan dalam rumah tangga sebagai lex specialis. Penyelesaian kasus kekerasan dalam rumah tangga berdasarkan aturan tersebut, secara empiris lebih menekankan pada pemidanaannya, sehingga terlihat tujuan preventif, protektif, dan konsolidatif tidak terpenuhi. Kedua, penelitian ini menyimpulkan bahwa kekerasan dalam rumah tangga merupakan perkara dengan multi dimensi penyelesaian karena terdapat sisi lingkup perdata dan di sisi lain lingkup pidana. Oleh karena itu dibutuhkan suatu media di dalam sistem yang dapat mengakomodasi penyelesaian perkara tersebut, yang salah satunya adalah dengan menggunakan pendekatan restorative justice.

Published: March 2023

Dalam kehidupan sehari-hari kita selalu berinteraksi dengan sesama manusia, interaksi tersebut seringkali diwujudkan dengan sebuah perjanjian, pada mulanya perjanjian dibuat secara lisan, dalam perkembangannya adakalanya perjanjian tidak cukup dibuat secara lisan saja namun mengharuskan dibuat dalam bentuk tertulis, bahkan dengan alasan kepraktisan dan efesiensi untuk perjanjian yang sifatnya massal perjanjian dibuat dalam bentuk yang sudah dibakukan dalam sebuah formulir atau yang lebih dikenal dengan bentuk perjanjian baku (sandart contract). Para pihak diberikan kebebasan untuk menentukan hal-hal apa saja yang dituangkan/dibuat dalam sebuah perjanjian, Adanya kebebasan yang diberikan kepada para pihak dalam menentukan isi perjanjian dimaksudkan karena para pihak dianggap mempunyai kedudukan yang sama dan seimbang. Namun dalam kenyataannya kedudukan para pihak dalam sebuah perjanjian tidak selalu seimbang, apalagi dengan makin banyaknya diberlakukan perjanjian baku. Dalam perjanjian baku, isi perjanjian hanya ditentukanoleh salah satu pihak saja dan tanpa melibatkan pihak lainnya, maka syarat-syarat dalam perjanjian tersebut dibuat tanpa melalui proses negosiasi (tawar-menawar) dan hal ini rentan sekali terdapat penuangan klausula eksonerasi (klausula pengalihan/pembatasan tanggung jawab) dari pihak yang menentukan isi perjanjian. Adanya penuangan klausula eksonerasi dalam perjanjian baku kalau dilihat dari syarat sahnya perjanjian sebagaimana yang diatur dalam Pasal 1320 BW mengakibatkan perjanjian tersebut dapat dibatalkan karena tidak memenuhi syarat kesepakatan,disebabkan karena adanya cacat kehendak yaitu penyalahgunaan keadaan dari salah satu pihak yang menentukan isi perjanjian. Sedangkan kalau dalam perspektif Undang-Undang Nomor 8 Tahun 1999 tentang Perlindungan Konsumen, perjanjian baku yang mengandung klausula eksonerasi (pengalihan tanggung jawab) berakibat batal demi hukum.
Reframing African Girlhood
Authors: Mitchell Claudia
Published: March 2023

This Special Issue on African Girlhoods is long overdue for many reasons, not least of which is its recognition, as guest editors Marla L. Jaksch, Catherine Cymone Fourshey, and Relebohile Moletsane point out, of the somewhat vexed history of the discourse of the African girl-child that dates back to the global development literature of the early 1990s attached to the Fourth World Conference on Women: Action for Equality, Development and Peace, held in Beijing in September, 1995—typically referred to just as Beijing. This, and the many country and regional conferences leading up it were (and still are) game-changers in so many ways when it comes to the lives of girls and women. It would be remiss of me not to acknowledge that I participated readily in the early days of defining the girl-child when I was working as a short-term UNICEF consultant in Zambia to develop an agenda for the Ministry of Education and other policy actors for research about education for girls in Zambia. One of the events in which I participated in Lusaka in October 1994 as part of my fact-finding and local consulting was a meeting of 80 or more local NGO members and other Zambian women who were planning their submissions to the November 1994 African Platform for Action: Fifth African Regional Conference (Dakar) on Women preparatory to Beijing. As an observer at this meeting, I heard a presenter talk about the fact that she was one of the first women (if not the first) in Zambia to graduate from university. This was in 1994 and at the time I could see that giving any recognition and support to ordinary girls and their education was full of possibilities, if very complicated. But I regard all this as just as much a part of the development of Girlhood Studies as was the work in North America on girls and science in the late 1980s. As I note elsewhere on charting girlhood studies (Mitchell 2016) we now know that just getting more girls into science was equally complicated.

Expanded feminist narratives on the girl child have paid little attention to how young girls have become agents of their own change and sharers of their own knowledge. In this study, we spotlight girls’ agency reinforced by institutions that transform them from recipient to agents of change and resilience. In this qualitative study, we deploy critical analysis and reflective argumentation to underscore how Women's Research and Documentation Center (WORDOC) of the Institute of African Studies University of Ibadan provided Do-It-Yourself (DIY) tactics to girls aged 10 to 18 between 2018 and 2019 at its annual WORDOC Girls’ Summit. We explore a version of African girlhood aimed at presenting institutional impacts that offer platforms for girls’ self-empowerment and girl-agency in Nigeria.

A Woke Approach to User-generated Content: How Product Involvement and Gender Influence What We Post
Authors: SÖYLEMEZ Kemal Cem
Published: March 2023

Although gender is often utilized as a dummy control variable in user-generated content research, studies are often conducted in online communities of products that are disproportionately used by male users. In a similar fashion, existing studies also concentrate on communities of high-involvement products, even though online communities of low involvement products are emerging. In continuation of Soylemez’s work (2021a), this study utilized ELM and the equity theory and investigated how two personal factors (gender and product involvement) influence the relative generation of brand-oriented and community-oriented content. The study found that members of high-involvement product communities generate more brand-oriented content than community-oriented content, whereas members of low-involvement product communities generate more community-oriented content than brand-oriented content. A significant gender-product involvement interaction exists. Managerial and theoretical implications are also discussed.
Teoman Duralı'nın Metafizik, Din ve Ahlak Anlayışı
Authors: YILDIZ İlhan
Published: March 2023

Teoman Duralı'nın metafizik anlayışını anlamak için öncelikle onun felsefe ve bilim anlayışını kavramak gerekir. Duralı, biyoloji bilimini felsefi bir bakış açısıyla incelemenin yanı sıra, Türk felsefe camiasına "felsefe-bilim" kavramını tanıtarak felsefe ve bilimin birbirinden ayrılamayacağı konusunda ısrar etmiştir. Felsefe ve bilim kavramlarını "felsefe-bilim" olarak bir arada kullanarak kendine özgü düşünme biçimini ortaya koymuştur. Bu nedenle felsefenin bilimsiz, bilimin de felsefesiz olamayacağını düşünen ve felsefenin hesap verebilir bir temelde yapılması gerektiği fikrine yaslanan Teoman Duralı, felsefenin bilimsel verilerden bağımsız olarak yürütülemeyeceği görüşündedir. Çünkü Duralı'ya göre felsefe açıklayamadığı sorularla uğraşmaz. Felsefe-bilimin ne olduğu ve Aristoteles'ten günümüze ne tür değişiklikler geçirdiği sorusu konusunda Duralı'nın düşünceleri son derece didaktiktir. Duralı'ya göre felsefe-bilim, mantık, kültür, fizik ve metafizik çalışmalara, canlılığa, evrime, ahlaka dayalı tek boyutlu düşünülemeyecek kadar kapsamlı bir çabanın ürünüdür. Duralı, felsefe ve bilimin özünün Aristoteles'in felsefe-bilim anlayışında saklı olduğuna dikkat çekiyor. Felsefe ve bilimin aksine metafizik ve dinin asla uzlaşamayacağını savunuyor. Metafizik, saf akılla inşa edildiği halde dinin akılla ispatlanamayacak bir içeriği vardır. Bu düşüncelerden hareketle Duralı'nın dine ve inanca karşı olduğu sonucuna varılmamalıdır. Duralı'ya göre inanç bir duygu ve his meselesidir. Ayrıca müminin inancına, kafirin de inkarına delil göstermesi mümkün değildir. Bu açıdan dini inanç konusunda hiçbir akıl yürütmenin olamayacağı sonucuna varmanın yanlış olacağını söyleyen Duralı, dinleri incelerken aklın dört temel ilkesinden hareket edilmesi gerektiğini vurguluyarak geçmişten günümüze metafizik, din ve ahlak konularını akıl ve mantık süzgecinden geçirerek anlatmaya çalışmaktadır.

Kanuni dönemini bizlere anlatan önemli kaynaklardan biri Avusturya elçisi Busbecq’in yazdıklarıdır. Osmanlı ile sık sık karşı karşıya gelen Avusturya, anlaşma zemini oluşturmak için kendini her anlamda iyi yetiştiren Ogier Ghiselin de Busbecq’i elçi olarak İstanbul’a gönderir. Busbecq, Osmanlı ile ilgili gözlem ve değerlendirmelerini arkadaşı Nicolas Michault’a 1555, 1556, 1560 ve 1562 yıllarında dört mektup şeklinde yazıp gönderir. Bu mektuplarda Osmanlı’nın üstün olma ve Avrupalıların geri kalma sebepleri mukayeseli bir şekilde anlatılmıştır. Osmanlı’daki Müslümanların gelenek ve görenekleri, inançları, çalışma hayatları gibi birçok konudaki durumları da çarpıcı bir şekilde anlatılır. Yine Osmanlı devlet ve ordu yönetimi ile padişahı, ayrıntılı olarak ele alınmıştır. Bununla beraber kendi ülkesindeki durumu da anlatan Busbecq, iki ülkeyi ve halkı mukayese etmiş ve Avrupa’nın Osmanlı’ya karşı nasıl ayağa kalkabileceğinin reçetesini vermekten geri durmamıştır. Bu çalışmada Busbecq’in söz konusu mukayeselerine dikkat çekilecektir.

Published: March 2023

OBJECTIVE

The aim of this study was to identify preoperative risk factors for postoperative coronal imbalance (CIB) in patients undergoing surgical correction for adult spinal deformity (ASD).

METHODS

A systematic search of articles about risk factors for postoperative CIB was conducted on electronic databases (PubMed, EMBASE, and Cochrane Library) according to the PRISMA guidelines. The methodological quality of the included articles was assessed using the Institute of Health Economics Quality Appraisal Checklist for Case Series Studies. Data regarding the patient population (demographics, diagnosis, and follow-up), pre- and postoperative radiographic and clinical data, surgical procedure details, and complications were extracted and summarized. Meta-analyses were performed when possible.

RESULTS

Nine studies comprising 838 patients were included. The pooled incidence of postoperative CIB was 26%; preoperative sagittal vertical axis (SVA) and type C imbalance (trunk shifted toward the convexity) were found to be the only primary risk factors for iatrogenic CIB (p < 0.001 and p = 0.012, respectively).

CONCLUSIONS

Baseline evaluation of a patient’s global alignment is of outmost importance when planning surgery for ASD. Type C coronal imbalance (trunk shifted toward the convexity of the main curve) and increased preoperative SVA put the patient at risk of postoperative CIB. Intraoperatively, care should be taken to properly correct the lumbosacral fractional curve.

Die Ukraine liegt mit mehr als neun Millionen Hektar Wald im europäischen Vergleich nur hinter Deutschland, obwohl sie ein waldarmes Land ist. Die Waldbewirtschaftung fokussiert sich auf Produktivität durch Kahlschläge und künstliche Aufforstung. Die Waldgesundheit wird durch Klimawandel, Landnutzungsänderungen und Landflucht beeinträchtigt, was Waldsterben und Brände zur Folge hat. Im Jahr 2020 brannten 185 000 Hektar Kiefernwälder ab. Der Krieg mit Russland und insbesondere Landminen haben 16% der gesamten Waldfläche beschädigt. Der Wiederaufbau der Wälder und der Schutz der Landbevölkerung erfordern besondere Managementansätze.

Authors: Zubkova Olga , Pyagay Igor , Pankratieva Ksenia , Toropchina Maria
Published: March 2023

The development of a comprehensive approach to preventing the pollution of natural objects is necessary due to the high requirements of environmental legislation for the discharge of industrial wastewater. Adsorbents are used in various industries to extract heavy metals from wastewater. In this study the possibility of using saponite clay as a raw material for the production of sorbent for the extraction of copper ions Cu2+ from industrial wastewater is considered, a recipe and technology of sorbent production are developed, and its chemical composition is established. It has been established that the optimum temperature for heat treatment of the sorbent and corresponds to 550 ºC, since at this temperature saponite extrudates acquire strength (strength 34.1 kg/mm2) and textural properties (specific surface area of pellets 22.803 m2/g), allowing them to be used as sorbents. The kinetics of molecular adsorption was studied using model solutions of copper (II) sulfate. The extraction efficiency of copper (II) ions from the model solutions is 93 %. Extraction efficiency of copper (II) ions from copper plating wastewater reaches 94 %. SEM results confirm the presence of metal on the sorbent surface.

The results of development, testing and implementation of the process of occupational safety culture management in a fuel and energy company including the assessment of current state, assessment of deviation, formation of control action and its implementation are presented. Using the methods of mathematical analysis, the components of occupational safety culture and criteria for their evaluation were developed. As a control action, a procedure for conducting behavioural safety audit was elaborated and implemented. Proceeding from the results of analysing average ratings of safety culture components among the employees prior to and after the introduction of behavioural safety audit, it was concluded that there was a statistically significant increase in the average values of 12 out of 16 ratings of safety culture components. Analysis of the results of 1,011 audits showed the absence of an “alarm area” at the enterprise. Introduction of the developed process management model promotes an increase in the efficiency of attaining a high level of occupational safety culture in fuel and energy companies.

Published: March 2023

The paper considers the problem of reducing greenhouse gas emissions in the process of coal mining during the coal mine methane utilization in power supply systems. An algorithm to form recommendations for the implementation of CMM generation is presented. A simulation model for one of the Kuzbass coal mines was developed in the PowerFactory software application. The simulation model considers the uneven nature of the power consumption of mining equipment. As a result of modeling, daily power consumption profiles and voltage levels in the coal mine power supply system were determined before and after the implementation of the proposed measures. Based on the results, the technical and economic effects was estimated, which consisted in reducing the direct and indirect carbon footprint, electricity and capacity fees. It has been established that the cost of carbon dioxide emission quotas significantly affects the investment attractiveness of cogeneration projects. Based on the results, recommendations are given to stimulate the development of small generation in coal mines.
Development of methodology for scenario analysis of investment projects of enterprises of the mineral resource complex

Published: March 2023

Theoretical and applied aspects of scenario analysis of investment projects of enterprises in the mineral resource sector of the economy are considered, its advantages and disadvantages are analyzed. Taking into account the organizational and economic features of mineral resources management, a number of new modifications of the scenario analysis method, aimed at solving an urgent problem - reducing the information uncertainty in assessing the expected efficiency and risk of investment projects, are proposed. The peculiarity of the proposed new modifications is the use of the interval-probabilistic approach in the implementation of the scenario analysis procedure. This approach is based on a moderately pessimistic system of preferences in obtaining point values of the investment project initial parameters. Fishburn estimates and the hierarchy analysis method were used to reduce subjective uncertainty. The maximum likelihood values in the sense of the maximum a priori probability are used as expected estimates. An additional indicator of risk assessment, which characterizes the probability of the event that the net present value of the project will take a value less than the specified one, is proposed. When analyzing one project, this indicator is more informative than the standard deviation. A statistical hypothesis was tested on the improvement of the validity of investment decisions developed using the modified scenario analysis method compared to the standard method.

Published: March 2023

One of the key parts of laser system of atomic gravimeter based on cold atoms is investigated. In order to construct optical system of atomic gravimeter the laser offset frequency stabilization is needed. Method for frequencydoubled fiber laser’s offset frequency stabilization is suggested and developed. This method is based on modulation transfer spectroscopy and the usage of fiber electro-optical modulator. The experimental scheme of this method is described. The error signals for offset frequency stabilization of frequency-doubled fiber laser are obtained. In order to maximize error signal’s amplitude, experimental parameters such as cell’s temperature, pump and probe beam intensities and electrooptical modulators signal amplitudes are optimized. The influence of polarization on error signal’s amplitude is investigated. It is shown that circular polarization allows to achieve error signal with higher amplitude. The achieved results can be applied to the construction of quantum gravimeter, quantum frequency standards and to the laser cooling experiments.

The standard air flow velocity measurement procedure has been developed in order to unify and standardize the measuring instruments used and data processing algorithms, reduce the development time and certify such standard methods. Sources of error in indirect measurements of air flow velocity in the range 3–105 m/s are investigated. The sources of instrumental error of indirect measurements are analyzed – pressure sensors with digital and analog output signals, pitot tube, temperature and relative air humidity sensors, atmospheric pressure sensors. It is shown that the greatest contribution to the instrumental error is made by measuring the pressure difference and atmospheric pressure. The errors of method, which depends on the measurement model, is considered. A new mathematical model of measurements is proposed, which includes optimal expressions for determining the density of moist air and corrections for compressibility and allows to reduce the methodological error, and requirements for the metrological characteristics of the measuring instruments used are developed, ensuring that the total error of indirect measurements of the flow velocity complies with the allowable limits of ±0,2 m/s. Recommendations are given on the use of measuring instruments and algorithms for processing measurement results, which make it possible to reduce the measurement error by 39 % and develop a standard air flow velocity measurement procedure. The standard procedure is relevant for aviation industry enterprises, where the air flow rate is measured by the pneumometric method.

Durante el cuarto trimestre de 2022, la economía de la región Centro siguió desacelerándose y algunos indicadores cayeron en términos anuales. La demanda interna dirigida a consumo continuó creciendo, y se prolongó la reactivación del turismo que motivó mayor movilización de pasajeros. Entretanto, los sectores agropecuario e industrial se tornaron levemente negativos, en parte afectados por el exceso de lluvias y altos costos de insumos, que mermaron la disponibilidad de materia prima. De otro lado, en construcción, se mantuvo un ligero ascenso en el área causada, al tiempo que la venta de vivienda nueva descendió, en parte atribuido a los menores los desembolsos hipotecarios ante las elevadas tasas de interés, mayor incertidumbre y precios al alza. Finalmente, la inflación en las capitales de la región continuó al alza, por encima del promedio nacional, mientras que la tasa de ocupación cayó en Ibagué y Neiva.

The aim of this article is to familiarize with the experimental and theoretical study of the load-bearing capacity of BFRP concrete beams damaged in previous studies and brought to failure, reinforced with carbon-plastic fabric in the lower stretched zone and carbon-plastic jackets in the supporting areas under the action of low-cycle sign-repeated transverse loading of high levels with the development of initial data for the physical model of the methodology for calculating the strength of their normal and inclined sections. The article presents the results of testing concrete beams reinforced with ВFRP, strengthened with carbon fiber reinforced polymer (CFRP) strips in the lower tensile zones and carbon fiber reinforced polymer jackets at support sections, previously tested to ultimate limit state (ULS). The load-carrying capacity of the reinforced FRP support sections of beam structures, brought to the ultimate limit state (ULS), should be determined primarily under the action of bending moment through the critical inclined crack. The performed experimental and theoretical studies have established the possibility and feasibility of strengthening damaged and brought to the boundary state (ULS) concrete structures with BFRP external fiber-reinforced plastics (CFRP) while observing the established technology. The bearing capacity of CFRP-reinforced damaged concrete beams with BFRP should only be determined for the action of bending moments along normal sections in elements with large (a/d = 3) and medium (a/d = 2) shear spans and along inclined sections in beams with small (a/d=1) shear spans.

The goal of this paper was to research the construction of gyro-stabilized video camera suspensions for drones used for mechanical video stabilization during video monitoring or aerial exploration. The quality of the image received from the drone depends on the quality of the video stabilization, and therefore the amount of useful information received. There are two main groups of video stabilization methods: optical-mechanical and digital stabilization. In order to maximize the quality of the image from the video camera of the unmanned aerial vehicle and to minimize the effects of camera shake, it is necessary to first perform mechanical-optical video stabilization, and then, if necessary, supplement it with digital stabilization. Only digital stabilization without mechano-optical is performed only for the purpose of making the drone cheaper. Optical-mechanical stabilization is usually based on gyroscope readings. In this work, comparative research of the following methods of mechanical stabilization of video from drones was conducted: based on 3-axis and 2-axis gyro-stabilized suspensions with one microcontroller and based on gyro-stabilized suspensions with encoders and several microcontrollers. Mechanical stabilization, in addition to leveling the position of the camera when maneuvering the drone, allows you to turn the camera to a convenient viewing angle for the operator of a drone. 2-axis and 3-axis suspensions with one microcontroller have become the most popular because of their convenience and practicality. 1-axis suspensions or rigidly fixed cameras are used less often. Rigidly fixed cameras are used as course guides for orientation in space by the operator of a drone. That is, such a camera makes it possible to understand the deviation of the drone from the horizon and to adjust the command to the operator for correct flight. Rigid cameras are also used on drones for drone racing competitions. A modular system based on magnetic encoders and several microcontrollers is just beginning to develop, but such a system has a number of advantages, although it is more complicated and expensive. The system provides high accuracy and reliability of stabilization. Each module of the system performs its task. In this way, the resources of microcontrollers are distributed. But its main feature is maintaining the position of the axis rotors relative to the encoder readings. This makes it possible to react very precisely to dynamic actions on the system during active maneuvering of the drone.

The problem of determining the optimal number and location of charging stations for electric transport within the settlement is being studied. To solve this problem, the criteria, factors and limitations of the optimal placement of charging stations were defined. Since the task included ensuring the comfortable operation of electric cars by citizens until 2025, it was necessary to forecast the number of electric cars that will be registered in the town of Cherkasy. For this, a portrait of the potential consumer was drawn up, and the potential capacity of the transport market was determined. Also, the key points of concentration of potential customers were determined, the level of charging stations for electric vehicles that will ensure their operation in the town of Cherkasy was selected, and the calculation of the optimal number of charging stations for the South-Western district of Cherkasy was performed. Since there are no regulations regarding the required number of charging stations for a certain fleet, it was proposed to adapt the regulations for gas stations by making corrections regarding the features of the technical charging process and the number of electric vehicle charges per unit of time. With the help of the method of hierarchical clustering, demand points in charging stations for electric cars were determined and a map of their location was developed for the residents of the South-Western district of Cherkasy. The cost of this project was also calculated. It can be concluded that the implementation of the project to provide charging stations for electric cars is profitable both from the point of view of material investments and from the point of view of the occupied useful area of town parking lots. The administration of Cherkasy may be interested in the implementation of this project under the terms of the city development program. This is due to the fact that the implementation of this project is expected to improve the town's environmental situation, generate profit from charging electric cars and sell new electric cars at car dealerships.

The components of the market competition of carriers on passenger transport routes of the city transport system are considered. It is shown that the demand for transportation can be presented in the form of matrices of passenger correspondence. Due to its fluctuations within some limits, the main issue is its distribution among the routes that form the urban route network. The essence of the level of competition between carriers, which has a growing tendency, has been revealed. It is proposed to use the Likert method and the results of a sociological survey to build a model of the attractiveness of routes as its assessment. The utility function of the route, the optimization function of Lagrange and the model of the choice of the passenger movement path were constructed. It is taken into account that transport enterprises operate in break-even conditions, and profit is a limitation when solving the task of improving the quality of public service.
