Assessing the impact of marine growth on the structural integrity of jacket platforms

ABSTRACT The marine organisms of the jacket platform will directly affect the surface roughness and hydrodynamic coefficient of the platform. Therefore, it is of great significance to effectively analyze the influence of the attachment of marine growth on the structural performance of the platform. Firstly, the distribution law of marine growth was established by the statistical data in Bohai Sea of China. Secondly, the hydrodynamic coefficients of the platform which were changed due to marine growth were determined, and the finite element model of the platform was established. Finally, the finite element simulation results of the platforms with attachment patterns of no marine growth, uniform marine growth, and non-uniform marine growth respectively were compared. It is shown that the calculation results of the platform with uniform marine growth were relatively conservative. Meanwhile, the attachment of marine biofouling produced a significant effect on the structural hydrodynamic load, etc. of the platform.

Fisher-Tippet Law Truncated Form for Loading Modeling of Machinery Structures

Introduction. Statistical data are used as a basis for assessing the reliability of engineering structures. However, incomplete data or inaccurate modeling of random variables may lead to an overestimation of reliability indicators. In practice, laws with infinitely decreasing or increasing distribution functions of an exponential family are usually used to model random variables characterizing the bearing capacity, load, and resource of engineering structures. To improve the accuracy of modeling of random variables, truncated forms of distribution laws are often used. These forms allow us to consider the random variable within a specified interval, excluding impossible values. Several studies have suggested using the Fisher-Tippett law with three parameters for modeling random variables related to the loading of engineering structures. The advantage of this law is that it limits the range of the random variable on the right side, but the left side of the distribution function decreases indefinitely, which is not ideal for load characteristics. To improve the accuracy of predicting random variables that characterize the load, it would be helpful to have a left-sided restriction using the Fisher-Tippett law. Currently, there are no descriptions of truncated forms of the distribution law in scientific literature. This article will explore the justification and development of a three-parameter truncated form of the Fisher-Tippett law and its use in calculation methods. The goal is to create a left-sided truncated version of the Fisher-Tippett distribution with three parameters to model random variables within a specific range.Materials and Methods. The article provides a detailed description of the history of the Fisher-Tippet law, including its three-parameter form, and justifies the need for obtaining its truncated form.Results. As a result of the research, a truncated form of the Fisher-Tippet three-parameter law in differential and integral forms was obtained and substantiated. The findings included graphs and calculations that demonstrated the normalization of a random variable within a given range.Discussion and Conclusion. The conclusion was drawn about the advantages and disadvantages of the truncated form of the Fisher-Tippet law. The possibility of its practical application in the schematization of random loading processes under operating conditions and testing of machine elements and structures to assess fatigue life and determine fatigue resistance characteristics was established. The direction of further research is related to the practical use of the truncated form, particularly with the need to develop a method for evaluating the parameters of the truncated distribution and verifying the consistency of the proposed model

Faktor Perubahan Alih Fungsi Lahan Pertanian Akibat Pembangunan Kawasan Aerotropolis Kulon Progo dan Dampaknya Terhadap Tata Guna Lahan LP2B, Pemukiman dan Pariwisata

The development of the Aerotropolis area in Kulon Progo Regency causes frequent changes in agricultural land use to residential areas, hotels, restaurants, and other infrastructure. The excessive rate of conversion of agricultural land will have a negative impact on Kulon Progo Regency. Therefore, it is necessary to know the factors causing changes in agricultural land use and their impact on LP2B areas, residences, and tourism. The research method used is descriptive-analytical with statistical data; observations of situational conditions and the results of interviews regarding the problem being studied will be analyzed and then explained more specifically and in depth. The results of the analysis show that the phenomenon of land conversion in Kulon Regency is influenced by internal factors, namely the strategic location of agricultural land and its proximity to public facilities. The productivity of the agricultural sector has decreased due to difficult farmer regeneration, which causes economic factors to emerge. Apart from that, it is also influenced by external factors, namely increasing population growth, increasing development of the trade and services sector, the COVID-19 pandemic, and government policies that facilitate the conversion of agricultural land. The impact is that land and agricultural productivity are decreasing while the area of residential areas and the tourism sector are increasing. As a result, the GDP growth rate in the agricultural sector decreased, while the accommodation and food and drink (tourism) sector and the service sector increased. This trend has the potential to reduce the implementation of LP2B in Kulon Progo Regency. Recommendations that need to be made are strengthening government policies regarding the protection of LP2B and the involvement of many parties from the community, private sector, NGOs (Non-Government Organizations), and local governments regarding the implementation of LP2B

Knowledge, attitudes and strategies on contraceptive utilization among adolescents: views from beneficiaries and parents in City of Kigali

IntroductionPregnancy among adolescents is a significant public health concern worldwide, particularly in developing countries, including Rwanda. Although contraception could be an effective tool to prevent unintended pregnancy, its utilization among adolescents is often low.AimThis study explored knowledge, attitudes and strategies on contraceptive utilization among adolescents.MethodsMixed method research (MMR) using a cross-sectional design, Sequential explanatory design was used to explore the views from 394 participants in Gitega Sector. This approach was chosen to first quantify the prevalence and patterns of contraceptive use through the questionnaire-based survey, and then to deepen understanding by exploring attitudes, beliefs, and experiences of adolescents and parents through in-depth interviews and focus group discussions. This sequential approach allowed quantitative findings to guide qualitative inquiry, providing richer context to the statistical data. For the quantitative phase, convenience sampling facilitated by the in charge of Health at the sector level and community health workers at the cell level ensured effective access to the study’s target demographic. Qualitative participants were purposively chosen to gain detailed insights from those identified with unique or significant experiences in the initial survey. Data were analyzed using SPSS version 25.0 for quantitative analysis and ATLAS.ti 23 for qualitative analysis.ResultsThe study found that both adolescents and parents (59.1%) have a low level of knowledge about contraceptive utilization, with adolescents (75.5%) showing significantly lower knowledge than parents (46.4%). A majority of the participants, 195 (56.7%), had a positive attitude towards contraceptive utilization among adolescents. Bivariate analysis revealed significant associations between knowledge and socio-demographic factors such as education (P = 0.00) and marital status (P = 0.00), indicating higher knowledge levels among those with higher educational attainment and married individuals. Additionally, attitudes towards contraceptive utilization were significantly influenced by occupation (P = 0.005) and religion (P = 0.00). However, challenges such as the lack of parent-child communication and low knowledge contributed to the low contraceptive usage despite the existing initiatives such as the INGOBYI Activity.ConclusionThe findings highlight a need for targeted interventions that address the specific challenges identified, including the lack of knowledge and communication barriers. Improved education and awareness programs for both adolescents and parents, along with supportive community strategies, may enhance contraceptive utilization. A concerted effort involving parents, healthcare providers, and community leaders may foster a supportive environment that encourages responsible and informed contraceptive use among adolescents.

Передумови та тенденції розвитку системи професійного навчання службовців органів публічної влади в Україні

This article is devoted to the theoretical substantiation of the prerequisites and tendencies in the development of the system of professional training of civil servants and employees of local self-government bodies (public authorities) in Ukraine. Within this article is a proposal for a hypothesis that the professional training provided by the relevant system is currently becoming the only factor capable of compensating for the needs of public authorities for employees who are able to effectively perform the functions and powers assigned to these bodies. It is determined that the prerequisites for the development of the system for professional training of public authority employees are the conditions for the existence of the components (parts) of the system for professional training existing at the time of its reform (within the framework of this article, at the beginning of 2024), and the tendencies in the development of the system of professional training of public authority employees are the main directions of targeted changes in its components (parts) during certain periods of its functioning. Based on the analysis of strategic documents (strategies, concepts, plans) for the management bodies of the civil service and local self-government system, the general and specific prerequisites and tendencies in the development of the system of professional training for civil servants and local self-government officials in Ukraine are identified. Based on the analysis of statistical data (needs of public authorities' employees in vocational training for 2024–2027, the amount of funding for vocational training of employees at the expense of the state budget for 2021–2024), the author identifies the correspondence between the priority issues of training, as the needs of employees, and the use of funds for it. At the same time, it is established that the State is not able to financially meet all the priority needs of employees in professional training, which requires the search for new mechanisms for the development of the professional training system, one of which is proposed to be the receipt of an annual certificate for professional training by employees. It is substantiated that, given the prerequisites and tendencies in the development for the system of professional training for public authority employees in Ukraine, it should be based on a combination of the principles of centralisation and decentralisation for each of its parts

Methodological approaches to the study of the causes of temporary disability at employees

Introduction. Temporary disability (TD) is one of the main indicators characterizing the state of health of workers. The legislation in force in the Russian Federation on the protection of personal data has significantly limited the possibilities of analyzing the incidence of temporary disability at the enterprise level. The study aims to evaluate the possibility of using the results of the analysis of temporary disability according to enterprise data in the risk management system for the health of workers. Materials and methods. The scientists used data from four enterprises of different types of economic activity with the number of employees from 1,647 to 5,882 people to assess the possibility of analyzing the causes of temporary disability, they also received information about all cases of temporary disability in the form of depersonalized personal data. For statistical data processing, specialists used Microsoft Excel 2013. Results. The company's own accounting data allows to consolidate and analyze personalized data on the causes of temporary disability of employees. The level of temporary disability can be determined considering the gender and age structure of employees, length of service, working conditions, profession and other characteristics of the workers. Limitations. The study is limited by the lack of information on diseases that cause temporary disability. Conclusion. At the present stage, it is necessary to develop new methodological approaches for analyzing the causes of temporary disability at the enterprise level, introducing them into systems of social and hygienic monitoring and risk management for the health of workers.

Sepsis-induced cardiomyopathy: understanding pathophysiology and clinical implications.

Sepsis is a life-threatening form of organ dysfunction resulting from a dysregulated response to infection. The complex pathogenesis of sepsis poses challenges because of the lack of reliable biomarkers for early identification and effective treatments. As sepsis progresses to severe forms, cardiac dysfunction becomes a major concern, often manifesting as ventricular dilation, a reduced ejection fraction, and a diminished contractile capacity, known as sepsis-induced cardiomyopathy (SIC). The absence of standardized diagnostic and treatment protocols for SIC leads to varied criteria being used across medical institutions and studies, resulting in significant outcome disparities. Despite the high prevalence of SIC, accurate statistical data are lacking. To understand how SIC affects sepsis prognosis, a thorough exploration of its pathophysiological mechanisms, including systemic factors and complex signalling within myocardial and immune cells, is required. Identifying the factors influencing SIC occurrence and progression is crucial and must be conducted within specific clinical contexts. In this review, the clinical manifestations, pathophysiological mechanisms, and treatment strategies for SIC are discussed, along with the clinical background. We aim to connect current practices with future research challenges, providing clear guidance for clinicians and researchers.

The study aims to determine the characteristics of the production potential of food industry enterprises, assess their current state, and determine directions for increasing the efficiency of production potential in martial law conditions. The research methodology involved using existing modern scientific and empirical achievements and recommendations regarding the peculiarities of the formation of the production potential of food industry enterprises. Official statistical data were used to analyze the size and scope of production, the efficiency of using labor resources, and the volume of capital investments. The time range covered 2021-2023. Indicators characterizing the efficiency of the functioning of enterprises include the volume of manufactured and sold products, the value of which increased by 15.5% and 20.6%, respectively. The number of workers employed in the production of products tended to decrease (-6.8%). The main problems accompanying food enterprises as a result of hostilities were loss of relations with suppliers, lack of stable sales directions for manufactured products, reduction in the number of personnel due to the mobilization of part of the employees, reduction in the number of personnel due to departure abroad; instability of the credit and financial sphere (high interest rates on loans, instability of the national monetary unit); absence or instability of the supply of raw materials and materials, including gas, electricity, water; occupation of territories where enterprises operate. Despite the troubles, food industry enterprises restored the pre-war level of capital investment and exceeded it by 4.3%. The state needs to focus its efforts on the following areas: financial and credit and tax incentives and infrastructure support to increase the production potential. The following programs have already been implemented and are operating to support enterprises affected by military actions: loans for working purposes at 1% per annum; an increase in the provision of state guarantees to 80; increasing the limit under the “5-7-9%” program to 150 million hryvnias; conclusion of international trade agreements for the export of manufactured products; reduction of dependence on imported raw materials; quotas for the import of products that have a higher competitive position compared to domestic types of products; reduction of bureaucracy; referral of employees to retraining and training; stimulation of innovations, etc. Keywords: production potential, resources, size and scale of activity, food industry enterprises.

Stereomicroscopic Evaluation of the Apical Sealing Ability of Different Root Canal Sealers (Endoseal, Apexit, MTA Fillapex, Ceraseal) Using Diaphanization Technique.

Obturation of the root canal is the most critical step in endodontic treatment, which aims to provide a hermetic seal and prevent regrowth and entry of bacteria into the canal. To achieve this, many sealers are used in endodontics. To evaluate the effectiveness of the apical seal obtained by different sealers used in conjunction with the single cone obturation technique using gutta-percha under the stereomicroscope. Extracted human single-rooted teeth were taken and decoronated at the cementoenamel junction. The access cavity was prepared, and biomechanical preparation was completed. The samples were randomly assigned to four groups consisting of 20 teeth each according to the root canal sealer used and categorized as group I, group II, group III, and group IV. Group I (n = 20)-Endoseal (Prevest DenPro), group II (n = 20)-Apexit Plus (Ivoclar Vivadent), group III (n = 20)-MTA-FillApex (Angelus), and group IV (n = 20)-Ceraseal (Meta Biomed). The teeth were immersed in Indian ink for 7 days and finally transferred to methyl salicylate for diaphanization. The extent of dye penetration was measured using the stereomicroscope. Statistical data analysis was performed using analysis of variance (ANOVA) and the Tukey test. Microleakage was seen in all the groups. Apical leakage was maximum for the Endoseal group, followed by MTA Fillapex, Apexit, and Ceraseal. Groups were compared by one-factor ANOVA, and the significance of the mean difference was measured using Tukey's honestly significant difference (HSD) and post hoc test. A statistically significant difference in the depth of dye penetration was observed among the groups (F = 28.66, p < 0.001). It was concluded that there were statistically significant differences among the experimental groups. Ceraseal endodontic root canal sealer provided a significantly better apical seal, followed by Apexit and MTA Fillapex, whereas Endoseal showed the least sealing ability.

Engineering Training in the Structure of Higher Education and Professional Choice of Youth

The structural elements of the university network of engineers’ training and its demand in different social groups of young people are analyzed using statistical data, monitoring and sociological research results. Recent shift in the choice by school graduates towards engineering specialties is associated, first of all, with the expansion of employment and career opportunities, as well as the growing attractiveness of advanced technical qualifications. The concentration of personnel training for the development of breakthrough technologies in top, selective universities is effected by combining investments from the state budget, large corporations, the development of innovative forms of education, in particular within the framework of the Advanced Engineering Schools project, as well as investments of families with high cultural and economic capital to ensure competitiveness of future students. Successful training in mass engineering education programs in regional universities, where numbers of budgetary admission places have been increased since 2022, is hampered by a keen shortage of well-prepared school students-applicants. The best results are shown under the practice of attracting target social groups of young people while maintaining value of technical labor, for example, in various forms of mobilization via the track “School-SPO-engineering training in higher education institutions”.

Investigation of the statistical data on the technical condition of brake equipment components of passenger carriages in operation

In the article, a study was conducted on improving the efficiency of braking systems in railway transport. Based on the information obtained regarding the maintenance of passenger cars, an analysis of brake equipment component failures was performed. Key trends and factors determining brake equipment component failures were identified from the collected statistical data for the reporting period. The main brake equipment components with the highest number of failures were highlighted. It was established that a significant portion of transport incidents due to brake failures in passenger cars occurs during operation, negatively impacting traffic safety. The collected data on the failures of electro-pneumatic distributors in passenger cars were systematized using the specialized software package "STATISTIKA". The research established that seasonal factors influence the total number of failures. A diagnostic system for the braking equipment of passenger trains was proposed to ensure traffic safety. The diagnostic system allows for the construction and analysis of mathematical models that describe the operational state of the braking equipment of passenger rolling stock as a whole. The diagnostic system enhances the reliability of brake operation, monitors air pressure in the brake line, ensures the inter-repair periods of passenger car components, and reduces the time required to detect failures both en route and during train stops. Recommendations for diagnosing the braking system of passenger trains were developed for continuous inspection and timely identification of failures. Their application will enable the prediction of the lifespan of pneumatic and electro-pneumatic system components in passenger cars, ensure the inter-repair operational periods of cars based on their current technical condition, and enhance traffic safety in railway transport.

Unlocking the potential of social media on food additives for effective science communication

Ultra-processed foods dominate modern diets, often containing numerous additives to enhance flavor, texture, and shelf life. Concerns about the potential health risks of daily or excessive consumption have sparked online discussions. This study analyzed perceptions of food additives on Zhihu, a popular Chinese social platform. The findings revealed no significant difference in attitudes between experts and non-experts (p > 0.05), with experts relying on statistical data and non-experts drawing from personal experiences. An independent t-test indicated no significance in comment engagement (p > 0.05) among them. However, a chi-square test showed that experts were significantly more interactive, frequently replying directly to original posts and commenters (p < 0.05). This suggests that experts actively facilitate discussions, moving away from reliance on influencers and instead prioritizing high-quality, accessible scientific communication. The findings highlight the crucial role of interactive online platforms in bridging the gap between science and the public.
