Published: October 2024

Poverty is a multidimensional concept that can not only be seen from an economic perspective, but can also be seen from a social, cultural and political perspective. Poverty is generally expressed as a static concept with the amount of poverty as a description of welfare conditions at a certain time. In reality, poverty has a time period that is never cut off and has a continuous pattern over time. The Indonesian government is committed to efforts to eradicate poverty in order to reduce Indonesia's poverty rate. One way that can be done is by allocating aid to the community. Grouping is carried out by cluster analysis using the Gaussian Mixture Model method with the Expectation-Maximization (EM) algorithm. The optimal number of clusters in the Gaussian Mixture Model uses the Bayesian Information Criterion (BIC) method. Based on the research carried out, the results of the analysis of cluster grouping using the Gaussian Mixture Model method were obtained with the smallest BIC value, namely -397.6876 with a total of 2 clusters.
Особливості парламентського контролю над виконавчою владою в Іспанії
Authors: Годлевська Валентина
Published: October 2024

The article analyzes the parliamentary control over the executive branch in Spain. The exercise of the control function by the parliament is one of the most important components of its activity. The main purpose of parliamentary control is to identify key problems in the activities of state bodies, increase the efficiency of the public administration system and draw the attention of relevant state bodies and officials to the shortcomings identified during parliamentary control in order to eliminate them.
The main procedures of the Spanish parliament are legislative activity, parliamentary control over the activities of the executive branch, ratification of international treaties, the appointment of national referendums and some others. A study of Spanish constitutional practice and national legislation on the interaction of the legislative and executive branches of government confirms that the mechanism for reviewing the Government’s activities includes two main elements: parliamentary control and the requirement of political accountability of the Government. Parliamentary control is the responsibility of the General Cortes, both chambers, while the requirement of political responsibility is limited to the Congress of Deputies. The lower house of parliament plays a more important role in this process, as it can only implement the requirement of political accountability of the Government. However, the Senate, excluded from the latter, may also exercise control over the Government, using in this case the full range of means provided for in the Spanish constitutional system.

Published: October 2024

The article analyzes the participation of civil society institutions in the management of the higher education system in the United States on the basis of a wide range of sources and the latest research. The author analyzes the federal legislation on higher education and the legislation of individual states. The study focuses on both the general federal system of higher education management and the management system at the state and higher education levels. At these levels, the participation, role, and forms of interaction between civil society institutions and governing bodies in the US higher education system are also analyzed. The paper also points to the general characteristics of higher education systems at the state level. Their general features and some differences are determined.
The author notes that one of the most important features of the higher education management system in the United States is that general policy, supervision, and even accreditation of higher education institutions remain decentralized. It is determined that civil society institutions (organizations, associations, foundations, etc.) interact with governing bodies at all levels of higher education management. It is proved that the federal legislation on higher education does not contain norms on the general management system, but is aimed mainly at financial grant support for both students and higher education institutions. State higher education management systems generally have a similar structure, in which legislators and executives organize state support and financial, planned coordination function. Public and private higher education institutions (colleges and universities) operate on the principles of broad autonomy. It is substantiated that at the university level, civil society institutions are also widely represented. Their representatives can be members of the board (regent’s council, coordinating council, board of trustees, etc.) and university senates.
At the level of higher education management, the alumni council plays an important role. They are often the main investors of higher education institutions, and sometimes are members of their boards of trustees. Stakeholders also play an important role in the management system of higher education.

The purpose of the study is to clarify the definition of "medical service" from the point of view of the theory of value for the relevant emphasis on the defining characteristics of its quality, which will serve to increase the effectiveness of the marketing positioning of the services of medical institutions in market conditions. The article substantiates the author's position that it is appropriate to take the value theory methodology as the basis of marketing positioning in the market of medical services. Based on a value-oriented approach in management theory, as well as based on the essence and goals of marketing positioning as a tool for influencing consumer behaviour, the article analyses the key characteristics of marketing positioning strategies in relation to market offers of medical services. Priority in this positioning of quality issues is emphasized. Emphasis is placed on the fact that in the medical field the concept of quality has the most subjective dimension of all possible types of services in other areas of human activity, since the quality result from treatment depends not only on the qualification of the doctor and the perfection of treatment protocols, but also on the general state of health. I of a specific patient and his psychological state. Therefore, an important characteristic of the quality of medical services in their marketing positioning should be the quality of service. In the work, on the example of family medicine services, other characteristics of their quality are highlighted, the specificity of which affects their consumer value. It is emphasized that such differences must be taken into account and properly broadcast to the target audience for their positive perception.

Published: October 2024

Polybutylene terephthalate (PBT) has complex, brittle properties and low-impact strength. This study uses polypropylene (PP) to increase the unnotched impact strength of the PBT/PP composite. The composition in the samples measured the mechanical properties of the PBT/PP mixture, which was mixed according to the PP content of 0, 5, 10, 15, 20, and 25%, respectively. It used an injection molding machine to create samples. After the injection molding, the samples are graded and tested for unnotched impact strength according to ASTM D256. The obtained results show that when adding a certain amount of PP, the unnotched impact strength of the mixture increases significantly, precisely 63.2%, compared to neat PBT. In addition, the results of microscopic imaging were used to study the compatibility of two phases, PBT and PP, in the PBT/PP mixture. Microscopic analysis showed that PP particles dispersed well on the PBT substrate at the ratio of PBT/5%PP and PBT/10%PPP. Additionally, there is no compatibility between the two phases, PBT and PP.

Published: October 2024

High-temperature carburizing heat treatment of 18CrNiMo7-6 steel was carried out at 930 °C, 950 °C and 970 °C. The effects of carburizing process on the microstructure, hardness and wear resistance of 18CrNiMo7-6 steel were studied. The results showed that the microstructure after high-temperature carburizing was mainly tempered martensite, and there were more carbides with carburizing temperatures of 950 °C and 970 °C. After carburizing at 950 °C and 970 °C, the effective hardened layer depths increased by 1.5 and 1.7 times, respectively, compared to that after carburizing at 930 °C. The average friction coefficients after carburizing at 930 °C, 950 °C and 970 °C were 0.66, 0.62 and 0.57, respectively. With the increase in carburizing temperature, the friction coefficient gradually decreased. Moreover, the total processing time also decreased from 139.5 h at 930 °C to 62.5 h at 950 °C and 46.5 h at 970 °C. Therefore, improving the carburizing process can shorten the total process time and improve the production efficiency while ensuring hardness and wear resistance.

Mathematical Modeling of Normal Contact Vibration and Its Influence on Friction Force
Authors: Ivlev Vladimir I. , Misyurin Sergej Yu. , Nelyubin Andrey P.
Published: October 2024

A mathematical model of normal vibrations in the contact of rough bodies during their mutual movement is presented. The rigidity of the contact is modeled by a cubic trinomial, and the occurrence of oscillations occurs due to kinematic excitation when the slider model moves along the rough surface of the counterbody. The roughness profile is described by a correlation function and the corresponding spectral density. The solution to the nonlinear equation of motion is sought by the method of successive approximations, highlighting the constant component in the solution, which determines the “floating” of the slider. The latter, in turn, leads to a decrease in the actual contact area and a decrease in the adhesive component of the friction force. The obtained dependences of the friction adhesive component force on the sliding speed are qualitatively consistent with the data available in the literature. The model can be used to estimate the friction force speed characteristic depending on the contacting surfaces parameters and to determine the falling section of this characteristic, which in turn is responsible for the occurrence of self-oscillations during friction.

Published: October 2024

This paper presents the design of an inverter Maximum Power Point Tracking (MPPT) charge controller utilizing the DSPIC30F2010 microcontroller. Traditional inverter systems rely solely on grid connectivity to charge batteries, which can be unreliable. To enhance reliability, renewable energy systems are often integrated into inverter systems, providing an alternative charging source when grid power is unavailable. In this paper, the focus is on a renewable energy system which utilizes solar energy. The developed system incorporates a photovoltaic (PV) solar panel operating at up to 150Volts input voltage, with battery load voltage of 24Volts. To address variability in solar energy supply, we designed a 60-amp MPPT charge controller leveraging the versatile DSPIC30F2010 microcontroller. The MPPT charge controller in the design utilizes a buck converter to maximize the power extraction from the PV panels, to ensure optimum output power at various levels of solar intensity. Furthermore, the system employs various sensors, such as voltage, current, temperature, as well as battery voltage sensors, by which the DSPIC30F2010 microcontroller obtains variables for making real-time decisions. The designed approach enables efficient and reliable battery charging from solar as well as grid sources, resulting in optimal system performance.

Published: October 2024

To monitor the operational status of materials transported by the transmission line material ropeway, research on the distance monitoring method between the load position and the trestle of the material ropeway transportation was conducted. Based on the requirements for measuring the load position of the material ropeway, a vision measurement method suitable for measuring the distance between the load position and the trestle of the material ropeway was proposed using monocular vision technology. The AprilTag Tracking marking and tracking function was adopted to measure the distance between the running car and the trestle. Through testing, it was found that the measurement accuracy of the standard 2.8mm lens meets the requirement of not less than 150mm. This method can be used for monitoring the distance between the load position and the trestle of the material ropeway, which is convenient for the construction site to run and stop the material ropeway through the saddle in time according to the distance, thereby improving the safety of material transportation of the material ropeway.

Published: October 2024

A 3D FEM of “SSP-stratum” was established by ABAQUS. Multi working condition numerical simulation analysis was carried out, compared and analyzed the on-site bearing test data of screw pile to determine the true friction coefficient between pile and soil, and studied the influence of geological conditions and structural types on the bearing performance of pile. Research had shown the pile-soil friction coefficient was about 0.6. Increasing the Young’s modulus of the stratum helped to improve the bearing performance of the screw pile. The compressive bearing capacity of circular steel pipe + screw pile (CSSP) was about 2 times higher than that of circular steel pipe (CSP), and the compressive bearing capacity of circular steel pipe + large blade + screw pile (CSBSP) was about 2.4 times higher than that of CSP. The tension bearing capacity of SSP was about 3.4 times higher than that of SP, and the tensile bearing capacity of CSBSP was about 4.9 times higher than that of CSP. The large blades enhanced the load-bearing capacity of the screw section and optimized the stress distribution of the structure.

Published: October 2024

The generation of hydrogen through water electrolysis is one of the primary choices for converting electrical energy into chemical energy. However, to meet the projected demand, cost reduction is required through simplification and standardization that allows for large-scale manufacturing. Regarding electrode materials, stainless steel emerges as a suitable option for alkaline electrolyzers due to its chemical composition and the properties it imparts to this material. Therefore, the behavior of stainless-steel 316L electrodes with a corrugated design over their surface was studied. It was performed in an alkaline medium using an electrolytic cell that permits to evaluate different gaps between the electrodes. Two corrugated geometries were constructed (A and B). For the construction of each type of geometry, its manufacturing method is proposed and analyzed. The pair of electrodes called B were determined to have the appropriate stainless-steel design, under the specific operation conditions studied. They presented 28% higher current density than pair A, which can be attributed to the shape of the channel that favors the detachment of bubbles. Between the two techniques employed in constructing the pair of electrodes, the method utilizing the matrix proves to be more accurate and reproducible, especially when considering large-scale production.

Authors: Kha Richard , Jin Ivan , Tang Diana , Liew Gerald , Craig Ashley , Burlutsky George , Mitchell Paul , Gopinath Bamini
Published: October 2024

_Purpose:_ Age-related macular degeneration (AMD) is a leading cause of visual impairment in older adults. Individuals affected by AMD often require regular physical and emotional support by family caregivers. Carers of people with AMD endure significant physical burden, emotional distress, increased financial stress, and disruptions due to their lifestyle and retirement plans as a direct consequence of the AMD caregiving experience. Despite this, there are currently no interventions targeted towards family caregivers of AMD patients. We evaluated the efficacy of a novel intervention aiming to improve the burden and wellbeing of family carers of persons with age-related macular degeneration (AMD).

_Methods:_ Family carers of relatives with AMD were primarily recruited through private eye clinics and randomised 1:1 to either receive a 10-week intervention of mail-delivered cognitive behavioural therapy (M-CBT) and optional telephone delivered group counselling (n=47); or to a wait-list control group (n=47). Outcome measures were assessed pre-intervention (baseline) and 6-months post-intervention. These included treatment acceptability, caregiver burden, presence of depressive symptoms, self-efficacy, quality of life and fatigue.

_Results:_ A total of 94 participants were enrolled, with 47 randomised to each arm. 77% of participants reported that they were satisfied/very satisfied with the intervention. Of those who participated in the telephone counselling component, 93% were satisfied or very satisfied. 87% of participants also indicated that they would recommend the program to others, and 84% thought the program was worth their time. Intervention participants demonstrated several positive non-significant improvements versus control group at 6-months: burden (_P_=0.53), depressive symptoms (_P_=0.19), general self-efficacy (_P_=0.14), quality of life (_P_=0.17) and fatigue (_P_=0.15).

_Conclusions: _Study findings demonstrate that combined M-CBT and telephone counselling intervention appear to be feasible, but did not lead to non-significant improvements in outcomes measures such as burden in family carers of persons with AMD.

Cumulant method for identifying spatial distributions of laser beam intensity
Authors: Raitsin A. M.
Published: October 2024

The article considers the identification of spatial distributions of laser beam intensity, which is of significant practical importance for laser developers when certifying radiation sources. As an identification parameter, a measure of similarity of the measured axisymmetric distributions of laser radiation intensity with a given Gaussian distribution is proposed and investigated. To determine this measure, it is not necessary to first find the beam width at the waist. A mathematical apparatus for identification based on the use of cumulants of spatial intensity distributions is developed. A feature of the method is a limited number of cumulants of the Gaussian distribution, which makes it attractive for practical application. A comparative analysis of a number of two-dimensional distributions with a Gaussian distribution is carried out and it is shown that even with a small number of measured cumulants, high sensitivity of the method to the shapes of intensity distributions is ensured. A similarity measure for continuous one- dimensional intensity distributions of arbitrary shape is presented. The asymmetry measure of two-dimensional spatial distributions of laser beam intensity based on the ratio of moments and cumulants of the fourth and second orders is considered. The proposed measure of similarity of the measured axisymmetric intensity distributions with the Gaussian distribution is an alternative to the well-known propagation coefficient M 2 and can be used together with this coefficient.

Стаття є черговою спробою дослідити особливості правового статусу центрального органу виконавчої влади зі спеціальним статусом. У дослідженні здобуло подальшого розвитку наукове уявлення про адміністративно-правовий статус Комісії з регулювання азартних ігор та лотерей як уповноваженого органу державного регулювання у зазначених сферах. Вивчення правового статусу проводилося шляхом поєднання загальнонаукових методів аналізу та синтезу: розчленування статусу на три окремі компоненти (цільовий, структурно-організаційний та компетенційний блоки) та оцінка абстрагованих результатів пізнання у єдиному і взаємному зв’язку. Для кращого розуміння особливостей та функціонального спрямування повноважень Комісії з регулювання азартних ігор та лотерей пропонується розподілити їх на основні та додаткові. У складі першої групи за функціональним призначенням виокремлюються нормотворчі, розпорядчі (дозвільні), установчі, обліково-реєстраційні, регуляторні, моніторингові, контрольно-наглядові та адміністративно-юрисдикційні повноваження. У складі другої групи – повноваження інформаційного забезпечення та методичного супроводження, представницькі, організаційні, превентивні, комунікативні та обліково-статистичні повноваження. У сукупності наведені основні та додаткові повноваження здатні забезпечити реалізацію особливих державних завдань у вказаній сфері. Констатовано, що за низкою ознак правовий статус Комісії з регулювання азартних ігор та лотерей задовольняє основним рисам центрального органу виконавчої влади зі спеціальним статусом, але відповідність не є абсолютною. Суттєвою відмінністю правового статусу Комісії від інших державних органів зі спеціальним статусом є відсутність спеціального закону про цей Уповноважений орган.
ОРГАНІЗАЦІЯ СЛУЖБОВОЇ ПІДГОТОВКИ ПОЛІЦЕЙСЬКИХ

Published: October 2024

В статті здійснено аналіз процесу організації службової підготовки поліцейських. Зроблено висновок про те, що сучасний процес організації службової підготовки поліцейських в Україні потребує часткового переформатування шляхом її оптимізації, поліпшення організації та адаптації до нових викликів. Серед основних проблемних моментів в організації службової підготовки авторами наголошено на таких: недостатня ефективність традиційних форм навчання, відсутність систематичної оцінки якості підготовки, обмеженість ресурсів, як матеріальних, так і людських, наявність потреби до подальшої інтеграції з міжнародними стандартами. Запропоновано розширити спектр форм навчального процесу шляхом запровадження додаткових занять, а також сертифікатних програм, які є ефективним інструментом для підвищення кваліфікації та спеціалізації поліцейських у різних напрямках поліцейської діяльності. Зроблено висновок про доцільність створення кадровим підрозділом центрального органу управління поліції Каталогу тьюторів, у вигляді систематизованого переліку фахових осіб, які можуть і готові залучатися до процесу організації службової підготовки територіальними підрозділами, а також Каталогу додаткових навчально-тренувальних баз, до переліку якого можуть включатися спеціально обладнанні об’єкти, навчальні платформи, наявні у партнерів. Виокремлено принципи, з дотриманням яких повинно здійснюватися формування тематичного плану службової підготовки, до яких автором віднесено такі: ефективності, доцільності, пропорційності, маневреності, науковості. Наголошено на необхідності проведення оцінювання рівня задоволеності поліцейських організацією службової підготовки отримання зворотного зв’язку від осіб, які проходили навчання, що, на думку автора, стане одним із дієвих заходів, спрямованих на удосконалення її організації та підвищення ефективності її заходів. Запропоновано внесення ряду змін до норм Положення про організацію службової підготовки працівників Національної поліції України, затверджене наказом МВС України від 26 січня 2016 року №50..
ПРАВОВА РЕГЛАМЕНТАЦІЯ ВИКОРИСТАННЯ ПОЛІГРАФА В СЕКТОРІ БЕЗПЕКИ І ОБОРОНИ УКРАЇНИ
Authors: Градун Світлана Анатоліївна
Published: October 2024

У статті проаналізовано міжнародний досвід застосування поліграфа та виконано систематичний аналіз положень чинних нормативно-правових актів, що регламентують використання поліграфа в секторі безпеки і оборони Україні. Зазначено, що діяльність, пов'язана з використанням поліграфа, регулюється окремими підзаконними актами, наказами та відомчими інструкціями, які переважно належать до компетенції сектору безпеки і оборони України та поширюються виключно на дослідження співробітників цих установ. Водночас підкреслюється відсутність основного закону, який би регламентував застосування поліграфа на загальнодержавному рівні. Проте не існує заборони на використання поліграфа, що дозволяє його застосування на загальноприйнятих правових засадах – лише за згодою опитуваної особи, без порушення прав і свобод. Наголошено, що під час досудового розслідування поліграф може використовуватися тільки під час проведення психологічних експертиз, а результати його застосування офіційно вважаються значимими орієнтуючими інформаційними даними для кримінальних, цивільних, адміністративних, господарських та інших проваджень, а також для забезпечення запитів зацікавлених фізичних та юридичних осіб. Обґрунтовано необхідність ухвалення єдиного законодавчого акту про поліграф, який би легалізував його використання, зокрема Закону України «Про застосування поліграфа та захист прав осіб, які проходять дослідження». Викладено позицію щодо окремих аспектів нормативно-правового регулювання проведення опитувань із використанням поліграфа.
