Background: In the film industry, producers and distributors are responsible for producing quality films and ensuring they are effectively accessible to audiences. Therefore, the right distribution strategy is crucial to a film’s success in the market. Effective film distribution contributes to increased visibility of film works, revenue for producers and distributors, and awareness of film culture and stories. The same also applies to film production in Makassar. Local filmmakers often experience many obstacles in distributing films, ranging from limited budgets to the need for more screens due to a lack of audience enthusiasm. Therefore, marketing public relations is needed to reach the audience. Purpose: Therefore, analysing the barriers to distribution and promotion undertaken by filmmakers in Makassar is important to determine the proper distribution and promotion. Methods: This research uses qualitative research methods and uses a case study approach. Results: The research found that cinema remains the primary distribution channel for Makassar films despite limited screens and monopolistic practices. Filmmakers face challenges like unfavourable screening times and locations.

Objective: This study investigates remote sensing techniques for monitoring and environmental planning in areas with a higher risk of wildfires in the São Nicolau watershed, located in the municipality of São João Evangelista-MG, Brazil.

Method: The research employed a quantitative approach, analyzing a 30-year historical series and incorporating nine significant variables influencing wildfire risk. The data were processed and analyzed using advanced geotechnologies, enabling the mapping of risk areas.

Results and Discussion: The results indicate that the study area comprises 3.02 ha of low risk (0.13%), 3,835.66 ha of moderate risk (16.35%), 17,540.28 ha of high risk (74.79%), 2,073.87 ha of very high risk (8.84%), and 0.18 ha of extremely high risk (0.00%). These findings reveal the predominance of high-risk areas, highlighting the urgent need for mitigation measures. Wildfire risk maps represent the areas most prone to fire on a base map, integrating factors that influence fire ignition and spread. Based on this information, various measures can be implemented, such as increased surveillance in high-risk areas, restricted access, construction of preventive firebreaks, and reorganization of management practices (Ferraz & Vettorazzi, 1998).

Research Implications: The findings provide valuable input for strategic planning of preventive actions against wildfires, contributing to public policies for environmental conservation and sustainable management in critical areas.
El nuevo régimen de habilidades del empleado público. Desde los deberes éticos a los factores críticos para la eficacia
Authors: Cabrera-Domínguez José María 
Published: January 2025

Objetivos: el objetivo de este trabajo es verificar que las sucesivas tentativas de reforma administrativa no alteran los deberes tradicionales, lo que no es incorrecto, pero parece insuficiente para alcanzar la eficacia que demanda el entorno actual. Para obtener esa eficacia, hay que orientarse a algunas llamadas habilidades blandas: el liderazgo, la comunicación, la negociación y la innovación. Ese resultado de eficacia debe girar sobre las competencias de la persona, poniendo el acento en los tres subsistemas más importantes: la selección, la formación y la dirección pública profesional, es decir, el liderazgo interno. Metodología: para llegar a esa conclusión, el enfoque de este trabajo es la recopilación de opiniones doctrinales que indican las carencias del modelo actual y que orientan el objetivo central de la renovación hacia las competencias de la persona que ocupa el empleo público, en especial, las indicadas previamente. Resultados: el trabajo limita su opinión, en forma de resultados, a la definición de criticidad de tres elementos en el resultado final: la selección, la formación y el liderazgo interno (a través de la dirección pública profesional). Conclusiones: las conclusiones reclaman agregar nuevas habilidades para el empleo público del siglo XXI, sin perder su componente tradicional (sistema de valores públicos). En un contexto de gobernanza, determinados subsistemas del empleo público (selección, formación y dirección pública profesional) deben ser los protagonistas esenciales de las reformas del empleo público.

Published: January 2025

Предлагается метод тепловой диагностики трения, позволяющий определять момент трения в самосмазывающихся подшипниках скольжения по температурным данным с учетом вращающего движения вала. Температурный режим в узле трения описывается в неподвижной цилиндрической системе координат двумя уравнениями теплопроводности. Уравнение для вала содержит конвективный член, учитывающий вращение вала с известной скоростью. Приводится методика определения временного шага при численном решении уравнений, обеспечивающего сходимость приближенного решения с точностью, пригодной для практического использования. Сопоставлением расчетных и экспериментальных температур показана адекватность модели реальному тепловому процессу в подшипнике скольжения. Момент трения в подшипнике скольжения определялся по температурным данным путем решения обратной задачи теплопроводности. Сравнением расчетных и экспериментальных значений момента трения установлена эффективность тепловой диагностики трения.
A method of thermal diagnostics of friction is proposed, which makes it possible to determine the friction torque in self-lubricating sliding bearings using temperature data, taking into account the rotating motion of the shaft. The temperature regime in the friction unit is described in a fixed cylindrical coordinate system by two heat conduction equations. The equation for the shaft contains a convective term that takes into account the rotation of the shaft at a known speed. A technique is presented for determining the time step in the numerical solution of equations, ensuring the convergence of the approximate solution with accuracy suitable for practical use. A comparison of calculated and experimental temperatures shows the adequacy of the model to the real thermal process in a sliding bearing. The friction torque in the sliding bearing was determined from temperature data by solving the inverse problem of thermal conductivity. By comparing the calculated and experimental values of the friction moment, the effectiveness of thermal diagnostics of friction was established.

Analysis of successful practices and determination of promising directions for implementing innovations in the sphere of housing and communal services in Russia
Authors: Mutolapov R. Kh. 
Published: January 2025

Since the key direction of modern development is the introduction of digital technologies in order to optimise all the aspects of economic activity, the main focus of the work is aimed at analysing the current state and prospects for the introduction of innovations in the housing and utilities sector (here-inafter referred to as HUS) from the point of view of digitalisation of the industry. To achieve this goal, we have used the analysis of statistical data in the context of the economic activities to determine the current level of innovative development of the HUS of Russia as well as individual indicators of the distribution and effectiveness of applying digital solutions in the industry. In the course of the work, it has been found that it significantly lags behind the average Russian indicators of innovation of innovative activity of companies, expenses on innovations as well as of modern products, works, and services. In the formation of the Russian “industry 4.0”, the HUS also demonstrates a significant lag in the development. The use of the most advanced and promising digital technologies is at an extremely low level, and the digital solutions applied in the activities of companies in the industry demonstrate extremely low efficiency rates, and most of them have virtually no significant impact on the work of the organisations. We believe that the negative experience of investing in the digital infrastructure is the reason for low involvement of the HUS companies in the fourth industrial revolution and low indicators of the innovative development on a national scale.
