Maximum permissible technological parameters of frame-filling filters
Authors: Shamyan Varuzhan L. , Kalantaryan Marine A.
Published: December 2023

Relevance. Wastewater of knitting industry contains various types of dyes, synthetic surfactants, mineral salts and suspended solids in values requiring deep cleaning. It is advisable to carry out deep cleaning of these drains on non-pressure filters, which do not require large expenses and are easy to operate. We gave preference to frame-filling filters. First of all, it allows significant increase in filtration rate, and its two layers with different fractions of filter materials significantly contributes to differentiated purification of wastewater from suspended solids of various sizes. Aim. To determine the maximum permissible values of technological parameters of the frame-filling filters operation (filtration rate and duration of the filter cycle) at which high filtration effect is provided through a highly porous material-crushed expanded clay. Objects. Wastewaters of the knitting industry and the effluents of the cotton and textile industries that are similar in their composition of pollution, as well as the identical effluents of some other branches of light industry. Methods. The experimental method was used on a laboratory frame-filling filter installation. The expanded clay used was obtained by the method of swelling low-melting clays and clay rocks during their rapid firing, followed by crushing to the state of sand. In general, the proposed technological methods are justified by those comparative and generalizing methods that can improve frame-filling filter operation. Results and conclusions. Based on the results of the conducted research, the following conclusions can be drawn:

Pronounced intergranular porosity (on average 1.6 times greater than that of quartz sand) allows expanded clay granules passing through a significant amount of waste water at relatively high filtration speeds (20–22 m h) and retain up to 70% of suspended solids
The duration of the filter cycle when using crushed expanded clay is at least 1.5 times longer than when using quartz sand
Due to the greater difference in the average coefficients of the shape of the filtering materials, more complete regeneration of filtering properties of crushed expanded clay compared to quartz sand is provided 2–3 minutes earlier, regardless of the initial concentration of suspended substances.
The filtering properties of crushed expanded clay during deep wastewater treatment of the knitted production with the main concentrated pollution indicators (color intensity, BODfull, COD and surfactants) practically do not concede the quartz sand properties. Besides, crushed expanded clay is much cheaper than quartz sand; it can be used on an equal footing with quartz sand for deep cleaning of low-turbidity and slightly colored industrial wastewater.

Relevance. The stock of oil wells in the Russian Federation, where production is carried out with the help of electric centrifugal pumps or electric-driven vane pumps, is expanding every year. This trend will continue for at least a couple of decades. In its turn, the number of wells with readily available oil products in the commissioned stock is decreasing. This leads to the need to improve production quality and reduce energy consumption to maintain profitability and production volumes. This can be achieved by implementing vector energy-efficient control systems for submersible motors based on observers of induction motor state variables. In this case one should take into account transients in the supply cable of considerable length, which transmits energy from a frequency converter to a motor. The observers are based on adjustable mathematical models that describe electrical, electromechanical and mechanical processes in electric drive and related process automation systems as reliably as possible. Using complex and cumbersome adjustable mathematical models in digital signal processors due to limited performance and memory causes objective difficulties in obtaining solutions of increased accuracy in real time. On this basis, the development of an analytical model of the dynamic system "long cable – submersible induction motor with fixed rotor" in the polar coordinate system is an urgent task. Aim. Development of analytical description of the mathematical model of the induction motor with a fixed rotor in the polar coordinate system taking into account the influence of a long cable. Methods. Electric drive theory, electric machine theory, mathematical models of submersible induction motors and reduced long cable model, Vandermonde's determinant, analytical methods for solving differential equations. Result and conclusions. The authors have developed an analytical model of the regulated induction motor with a fixed rotor in the polar coordinate system taking into account the supply cable of considerable length. The developed analytical model is recommended for use in vector energy-efficient electric drive with application of phase discrimination principles taking into account the influence of processes in the supply cable line. Such electric drive has a potential for increasing the profitability of oil production from low- and medium-debt wells.

Authors: Mamen Djamel , Abdessemed Dalila
Published: December 2023

Background: Prickly pears are abundant in the Aurès region but are intended only for direct human consumption, due to the limited processing of this highly perishable fruit. To enhance the use of this precious resource, prickly pear vinegar [Opuntia ficus indica L. Miller], enriched with seed powder, can be produced by a double biological fermentation process, first alcoholic then acetic. Methods: The Response Surface Methodology (RSM) was employed to optimize acetic fermentation process. This study investigated the influence of two independent variables, fermentation time and amount of added seed powder, on the chemical changes that affect five parameters (reducing sugar, ethanol, acetic acid, total phenolic and free radical scavenging activity) of vinegar obtained by the traditional method “Orléans”. Result: The fermentation time had a significant impact on all chemical properties examined, while the amount of added seed powder had a significant impact only on total phenolic contents and free radical scavenging activity. At the optimal point (fermentation time= 248.81 h and seed powder= 35.52%), the vinegar produced contained 1.73±0.31% reducing sugar, 0.42±0.02% ethanol, 5.55±0.5% acetic acid, 1670.14±2.9 mg GAE/L total phenolic and 61.33±0.45 mg AA/100 mL free radical scavenging activity. As a result, prickly pear vinegar enriched with seed powder was successfully made. It has a high level of bioactive components and a strong antioxidant potential, so it can be used as a functional food.

A Comparative Analysis of Gifted and Typically Developing Secondary School Students’ Perceptions of the Future
Authors: UYMAZ Mehmet
Published: December 2023

This study is to examine the future perceptions of typically developing and gifted secondary school students. The participants consisted of sixth-grade students, typically developing and gifted, enrolled in two different secondary schools in the Marmara region of Turkey during the 2022-2023 academic year. The study, which was designed as a basic qualitative study, used a phenomenological study design. The future perceptions of typically developing and gifted students were assessed through story completion and drawing activities. The story completion activity revealed that the future literacy dimension of fictionalizing the future used the expressions corresponding to the dystopia (future anxiety) sub-dimension more intensely than the utopia (future hope) sub-dimension. In the drawing activity, it was observed that participants frequently used objects related to the Utopia sub-dimension. However, the fact that they did not include many expressions corresponding to the dimensions of preparing for the future, planning, and controlling the future shows that their future expectations are harmful and that they feel inadequate in terms of preparing, planning, and controlling against these negativities. For this reason, it would be beneficial to conduct studies on the development of future literacy skills in the curriculum so that students can take action to prepare for the future.
‘Coping with our kids’
Authors: Day Patricia
Published: December 2023

This article describes the content, delivery, evaluation and dissemination of a programme which, over a period of seven years, has been central to a mental health promotion strategy. The programme was the response of two school nurses to the devastating effects of mental health disorder on family life. They developed a practical and simple parenting programme, devised a four week course called ‘Coping with Our Kids’ based on the work of Carolyn Webster-Stratton (1992). A distinguishing element of the course has been its emphasis on groupwork, through which many parents have developed the commitment and motivation to strengthen their parenting skills. Extensive evaluation of the Webster-Stratton approach has shown greatly improved outcomes for children with behaviour and emotional problems (Scott et al, 2001 and Patterson et al., 2002).

Authors: YARDİBİ Fatma , FIRAT Mehmet
Published: December 2023

Objective: The objective of this study was to obtain solutions by modeling different covariance structures with Bayesian analysis methods in repeated measurement and to show its applicability to data in animal science.

Materials and Methods: This article focused on the analysis of the body weight data of 4154 weaned 8-month-old lambs. Repeated measurement analyses based on the mixed effect model were evaluated with Bayesian methods. Models were created for 12 different covariance structures. As the model comparison criterion, Deviation Information Criteria based on the relationship between the fit of the data to the model and the complexity of the model were used.

Result: Among 12 different covariance structures, the unstructured covariance structure was determined as a suitable structure for the data of this study.

Conclusions: It was concluded that various variance-covariance structures, such as body weight, can be easily modeled in repeated measurement data. Instead of PROC MCMC methods that require complex and computational difficulties and profound coding knowledge, it was presented a relatively user-friendly and fast procedure with its theoretical structure and demonstrated its feasibility. As a result of the literature review, this is the first study in which Bayesian methods solved a wide variety of variance-covariance structure models.

Authors: ALKAN Ümit , GÜNGÖR Celal
Published: December 2023

Objective: Health and safety signs are critical in communicating messages about potential hazards, safe practices, emergency procedures, and regulatory guidelines. The objective of this study was to investigate the understanding of safety sign comprehension among tractor operators in Türkiye's agricultural sector. It seeks to determine operators' knowledge of occupational safety and health signs, traffic signs, and tractor safety signs.
Materials and Methods: A total of 118 tractor operators from Izmir’s two districts (Menemen and Foça) were surveyed using a questionnaire. The questionnaire included demographic information, occupational safety and health signs (ISO 7010), traffic signs (Turkish Standards for Road Traffic Signage) and tractor safety signs (ISO 11684). Descriptive and inferential statistics were used to analyze the data.
Results: The mean comprehension score was 37.2% for fourteen occupational safety and health signs, 34.9% for seven traffic signs, and 28.0% for ten tractor safety signs. The mean comprehension score for all signs was 33.7%
Conclusion: This study shows that tractor operators poorly understand these signs. Engineering and administrative control measures, including training, should be considered to improve sign comprehension. In addition, the poorly understood signs should be revised to effectively convey the intended messages.

Authors: Touray Saikou , Nasution Damai
Published: December 2023

This study uses panel data of the top 10 non-financial companies in Turkey to analyze the impact of accounting information in predicting stock returns for period 1998 to 2019. The rationale behind choosing non-financial firms is based on the believed that financial firms have their own ways of financing and examining together with financial firms may reveal biased result. The panel least square is employed, the analysis revealed that only financial leverage, earning per share and growth opportunities have the capability of predicting stock returns in Turkey. Moreover, the outcome also revealed that a 1% increase in leverage will decline stock returns by 1.07%. On the other hand, earning per share and growth opportunity have positive effects on stock returns at 1% and 5% levels of significance, respectively. This implies that a 1% increase in earnings per share and growth opportunity will lead to an increase in stock returns by 1.8% and 2.1% respectively. However, capital expenditure and firm size are unable to predict stock returns.
DETERMINATION OF TAXPAYER (WP) COMPLIANCE WITH MOTOR VEHICLE TAX (PKB) IN SAMSAT MEDAN AND INFLUENCE FACTORS
Authors: Meidiaz Emily Vanessa , Subagyo
Published: December 2023

This research aims to find out whether service quality, perceived income level, tax sanctions and tax relief have an effect on motor vehicle taxpayer compliance at SAMSAT Medan. This research uses primary data by distributing questionnaires to motor vehicle taxpayers at SAMSAT Medan. The number of respondents who were sampled and completely filled out the research questionnaire was 194 respondents. The research model uses multiple linear regression analysis with data processing using SPSS. The results of the research show that service quality and tax sanctions have a significant positive effect on taxpayer compliance (WP) with motor vehicle tax (PKB) at SAMSAT Medan, while perceptions of income level and tax relief do not have a significant positive effect on taxpayer compliance (WP) with motor vehicle tax ( PKB) at SAMSAT Medan.
In developing knowledge, especially in the field of taxation, with this research, it will be a concern for study program managers to add portions of material related to taxation, especially regional taxes. Taxpayers are expected to provide information and input regarding the importance of motor vehicle owners paying motor vehicle tax on time. It is hoped that the Medan SAMSAT Office can provide input as a solution in order to improve and increase motor vehicle taxes in order to increase regional income. The limitations of this research are that there are still taxpayers who do not know about the tax whitening policy and there is a lack of information regarding when tax whitening is implemented.
EFFICIENCY MARKET HYPOTHESIS, RANDOM WALK THEORY, AND FINANCIAL RATIOS-STOCK RETURNS: A COMPARATIVE STUDY OF BANKS IN INDONESIA, INDIA, AND CHINA IN THE POST-COVID ERA
Authors: ADININGSIH TRIANA EVA
Published: December 2023

This research aims to analyze how financial ratios affect firm value, utilizing the Efficiency Market Hypothesis and Random Walk Theory for analysis. It focuses on banking sector companies listed on the Indonesia Stock Exchange (XIDX), India Stock Exchange (XBOM), and China Stock Exchange (XSHG) from 2022 to 2023. This quantitative study employs purposive sampling, resulting in 184 firm- year samples, with data gathered from annual reports. Regression analysis using SPSS version 26 is the chosen method. The findings suggest that India has the most efficient market, while Indonesia aligns with the random walk theory, indicating weaker market efficiency. Notably, variables like "Return on Average Equity" in Indonesia and India and "Impairment Loans to Equity" in India and China significantly impact stock returns. These varying influences underscore the importance of considering country-specific factors in stock return predictions. However, it's essential to acknowledge tha the models explain only a portion of the variance in the dependent variable.
A brief history of rabies in Haiti until the adoption of the One Health approach for its epidemiological surveillance and control
Authors: Millien Max François , Duclair Henry Robert , Suprême Fritzner , Augustin Pierre Dilius
Published: December 2023

Rabies was first identified in dogs and humans by a French veterinarian, Jean Lompagieu Lapole, in 1788 in the colony of Saint-Domingue, which later became Haiti. Rabies has continued to persist in the country despite some intermittent successes in combating this disease over the past 20 years. We are trying to understand why rabies, which has officially existed in the country for around 250 years, is still classified as a neglected disease and continues to result in cases of human mortality. For a significant period, until the implementation of the Haiti Animal Rabies Surveillance Program (HARSP) in 2011, there was no robust initiative to fight against rabies based on regular vaccination campaigns and an effective epidemiological surveillance system despite certain efforts made by the Ministry of Agriculture and Pan American Health Organization Project of Strengthening Public Agricultural Services (RESEPAG): Projet de Renforcement des Services publics Agricoles (PAHO) to increase dog vaccinations. The HARSP program was established with technical assistance from the Center for Disease Prevention and Control of Infectious Diseases (CDC) to control and eliminate rabies in the short term, according to the One Health approach. It was a passive surveillance system based on strengthening the rabies diagnostic capacity of the Veterinary Laboratory, training veterinary and public health technicians, and supporting rabies vaccination campaigns. This approach has resulted in effective cooperation between the Ministry of Agriculture and the Ministry of Public Health based on the “One Health” enabling the Ministry of Public Health to report daily on bite to the Ministry of Agriculture for further investigations. HARSP marked a pivotal moment in the Rabies Control and Elimination Program. Between January 2013 and December 2017, there were 9,342 reported human exposures to animals suspected of carrying rabies in Haiti. The number of Human exposures to rabies suspected animals in Haiti from January 2013 to December 2017 was 9,342 heads. Among these cases, 2.4% were confirmed, 4.9% probable, 17.8% suspected, and 74.6% discarded. The One Health rabies program has demonstrated the potential for achieving control of both animal and human rabies in Haiti if the ministries of Agriculture and Health commit unequivocally to continue their collaborative development efforts and adhere to HARSP methodology, including vaccinating over 70% of the dog population.

Стаття присвячена визначенню впливу нових антифрикційних композитних деталей на основі регенерованих шліфувальних відходів сталей Р2АМ9К5 та 5Х3В3МФС з домішками твердого мастила CaF2, оброблених за розробленими режимами тонкого ельборового шліфування, на якість друкованої продукції. Розроблені ефективні технологічні заходи з тонкої механічної обробки нових композитів, зокрема, з використанням ельборового інструменту, дозволили одержати високі параметри якості робочих поверхонь антифрикційних композитних деталей. Це забезпечило реалізацію ефекту перманентного змащення контактних поверхонь всього високообертового вузла тертя. Порівняння параметрів якості друку при оцінюванні їх за розтискуванням та суміщенням фарб показало, що при застосуванні базових литих антифрикційних втулок з литої латуні CuZn37 у вузлах офсетних циліндрів друкарської машини KBA Rapida 105 спостерігається нерівномірність суміщення фарб та підвищення розтискування внаслідок інтенсивного зношення деталей з литої латуні, що призводить до зростання браку друкованої продукції до 5 %. А застосування нових антифрикційних композитів на основі шліфувальних відходів легованих сталей з твердим мастилом зменшує брак продукції до 2,8–3,0 % при друкуванні як на офсетному, так і на крейдованому папері. Це пов’язано зі стабілізацією вузла тертя через надійну роботу самозмащувальних композитних деталей, які не потребують додаткового змащення рідким мастилом. Одержані результати показали високу ефективність і доцільність застосування у вузлах офсетних, друкарських, формних циліндрів друкарських машин композитних антифрикційних деталей на основі відновлених шліфувальних відходів легованих сталей, що містять у своєму складі тверде мастило CaF2, і є попередньо обробленими за новими технологіями тонкого шліфування. Результати досліджень показали, що застосування нових антифрикційних композитних деталей сприяє підвищенню якості друкованої продукції та зменшенню браку як мінімум на 2,0–2,2 %. Отримані дані свідчать, що використання нових антифрикційних композитних деталей на основі шліфувальних відходів сталей у вузлах офсетних циліндрів як альтернатива деталям з литої латуні CuZn37 сприяє збільшенню продуктивності роботи друкарських машин через зменшення часу для технічних зупинок обладнання, заміни запасних частин, ремонту та обслуговування робочих органів, що сприяє збільшенню безупинного терміну служби машин, дозволяє збільшувати об’єми замовлень та обумовлює підвищення загального обсягу виробництва поліграфічної продукції.

RECENT TRENDS IN TERMINOLOGY FORMATION IN THE FIELD OF SOFTWARE DEVELOPMENT
Authors: Kornieva Zoia , Kozak Iryna
Published: December 2023

The main objective of this article is to investigate the latest trends in the formation of terminological units in the field of software development and to identify translation difficulties of multi-component terms, which serve as a primary means of enhancing international communication in innovative developments and the interaction of the IT industry at the international level. The work is aimed at addressing the problems of forming and translating terms in Ukrainian technical documentation related to software development. The field of information technology is currently in a stage of active development, which complicates the work of Ukrainian professionals in improving business processes and communications. Specifically, the terminology of scientific-technical discourse in the field of IT development and programming is based on English-language terms.

One of the main factors complicating translation is the presence of a large amount of multi-component lexicon in the terminology system of computer English. The article analyzes technical terms in the field of software development, substantiates the peculiarities of forming terminological units, and traces methods of their translation into the Ukrainian language. The analysis results in the identification of word-formation models of complex term words. Another important aspect of the research is the enrichment of the analyzed terminological system with terms-abbreviations and acronyms. A conclusion is drawn regarding the peculiarities of translational transformations and the main difficulties encountered by translators during their work.
Study on Home-Based Direct Care Workers' Coping Responses to Workplace Sexual Harassment and Their Satisfaction With Long-Term Care Preventive Strategies
Authors: Hsieh Chia-Jung , Shih Ya-Ling
Published: December 2023

BackgroundPrevious research on workplace sexual harassment issues in long-term care rarely focused on home-based direct care workers. Additionally, few victims would formally report the harassment incidents, resulting in limited understanding yet huge impacts on improving long-term care quality.Purpose Built upon Donabedian’s structure-process-outcome framework, this study aimed to explore home-based direct care workers’ coping responses when encountering workplace sexual harassment (WSH) and examine factors influencing their satisfaction with organizational preventive strategies.MethodsThis cross-sectional study surveyed 217 home-based caregivers via convenience sampling. Research instruments included socio-demographics, personal experiences (perceived job hazard and harm severity of WSH), and satisfaction scale ratings. Variance analysis, Pearson’s correlation, and hierarchical regression analysis were performed for statistical analysis. ResultsCaregivers working at private LTC agencies expressed lower satisfaction with employers’ anti-harassment measures than public agencies. Part-time workers also reported lower satisfaction. While 22% of participants took no actions when harassed, 30.8% directly told the harassers to stop. Manpower load status (r=-.16; p<.01) and perceived workplace hazards (r=-.2; p<.01) were negatively correlated with satisfaction with employer's implementation of prevention strategy for WSH. After controlling for personal and job characteristics, perceived workplace hazards, Satisfaction with handling of encountered sexual harassment incident, and strategies provided by devices significantly predicted participants’ satisfaction with anti- sexual harassment strategies.ConclusionAs the first study based on Donabedian’s framework to examine home-based caregivers’ coping and influencing factors of satisfaction with anti-harassment strategies, the results can inform managerial guidelines for WSH and evaluate the adequacy of existing policies.

Authors: Mu'ammar Zuhdi , Sudarsono Heri , Rahmi Asri Noer , Hawariyuni Weni
Published: December 2023

Purpose – This study aims to analyze the influence of attitudes, subjective norms, perceived behavioral control, service quality, and religious tourism literacy on people's intention in recommending and returning to religious tourism destinations.Research methods – The data source for this research was a survey method with a questionnaire distributed via broadcast on social media. This research uses a quantitative data processing method using structural equation modeling partial least squares (SEM-PLS) analysis with the SmartPLS 3.3 statistical tool.Findings – The results of this study show that subjective norms (SN), attitudes (ATT), and religious tourism literacy (RTL) have a significant influence on the intention to recommend and revisit religious tourism. Meanwhile, service quality (SQ) and perceived behavioral control (PBC) were not accepted and did not have a significant effect on the intention to recommend and revisit religious tourism.Implications – The government can also focus on developing religious tourism literacy programs to increase public knowledge, which, in turn, can enhance interest, positive attitudes, and the intention to recommend and revisit. Considering these implications, destination managers and stakeholders can design more effective strategies to enhance attractiveness and visitor satisfaction and contribute to the sustainable development of religious tourism.Originality – This model adopts the Theory of Planned Behavior (TPB) by incorporating service quality and religious tourism literacy. Service quality and religious tourism literacy are considered appropriate factors to capture issues related to the community's intention to recommend and revisit religious tourism destinations
