Strength Training in Children: A Systematic Review Study

Background: With the increasing prevalence of sedentary lifestyles and childhood obesity, physical activity and exercise have emerged as essential pillars of health promotion in childhood. In this context, schools play a fundamental role as key players in the implementation of interventions that promote healthy habits and a more physically active life. Objectives: The purpose of the present study was to conduct a systematic review of the benefits of strength training in primary school students. Methods: The review was carried out using the Web of Science and Scopus databases, following the guidelines of the PRISMA statement and a PICO strategy. The studies were selected according to different inclusion and exclusion criteria, resulting in 11 scientific articles published in English during the last 5 years (2020–2024). The methodological quality of the studies was assessed using the STROBE checklist. Results: The results suggest that strength training with elementary school students improves physical and motor performance variables, as well as cognitive, psychosocial and health variables. Likewise, it can be observed that plyometric strength-training methods and unilateral and combined programs with aerobic and motor skills training are highly effective and favor adherence to physical exercise. This also demonstrates the importance and necessity of developing motor coordination skills from an early age, since they represent a determining factor in strength training as the exercises become more specific and complex. Conclusions: In conclusion, implementing strength training programs in primary education confers several benefits at an integral level for the students and is crucial to improving the lifestyle and quality of life of students.

Anthropometric Aspects and Athletic Performance in Women's Tennis

Background. In recent decades, the evolution of female athletes’ physical characteristics in women’s tennis has sparked interest, particularly regarding the influence of stature on success in Grand Slam tournaments. Objectives. This study aimed to analyze the evolution of the height of the finalists and winners of the women’s Grand Slam tournaments in order to evaluate whether height is a determining factor for success and whether this impact varies according to the playing surfaces. Materials and methods. A retrospective analysis of the heights of the finalists and winners from 2000 to 2024 in the four major Grand Slam tournaments was conducted: Australian Open, Roland-Garros, Wimbledon and U.S. Open. The data were compared between tournaments on fast surfaces (Australian Open and U.S. Open) and tournaments on slower surfaces (Roland-Garros and Wimbledon). Results. The findings revealed a significant increase in the average height of the finalists and winners in tournaments on fast surfaces, with a clear increase in the average height starting from 2021. In tournaments on slower surfaces, the average height showed more stable or slightly declining trends, suggesting that other physical qualities, such as mobility and endurance, may be key to success. In particular, the average height of the Australian Open and U.S. Open finalists indicated a continuous increase, while at Roland-Garros and Wimbledon the fluctuations were more contained. Conclusions. This study confirms that stature has a significant impact on success in Grand Slam tournaments, but this effect is mediated by the playing surface. In tournaments on fast surfaces, greater stature seems to give a competitive advantage, while on slower surfaces other physical factors can play a role. Future perspectives include exploring other anthropometric variables and analyzing their evolution in relation to the needs of modern gaming.

Calcul De L’esperance De Vie Des Chomeurs En Rrepublique Democratique Congo/Kinshasa (2021-2022) Par La Methode De Regression Logistique Binaire Floue.

The main objective of this research was to contribute to the empirical literature on the application of fuzzy binary logistic regression to the life expectancy of the unemployed in DRC/Kinshasa. Specifically, it aimed to evaluate the proportion of households living without employment (unemployed), identify the explanatory or determining factors of the life expectancy of the unemployed, and finally determine the effects of factors directly related to household living conditions. The data for this study were collected through a survey of 386 households in Kinshasa, selected using a non-probabilistic sampling method. Descriptive statistics, inferential statistics, and multiple regression based on the logistic model were used to identify the explanatory factors of the life expectancy of the unemployed. The results of this study reveal that most of the surveyed households are unemployed (92.49%). Logistic regression reveals that the explanatory factors that improve the life expectancy of the unemployed in Kinshasa are: level of education (secondary and graduate), parcel occupation status (owner), activity characteristics (informal), time allocated to informal activities, prioritized healthcare mode (modern medicine), income (medium and high), and access to drinking water. On the other hand, the factors that reduce the life expectancy of the unemployed are: low income and non-food expenditure (medium).

State policy towards the Jewish population of the Russian Empire during the First World War

Relevance. Back in the 18th century, the Russian Empire introduced a pale of settlement for the Jewish population. But the outbreak of the First World War in 1914 made adjustments to Russian legislation. An analysis of the state policy towards the Jewish population has led to the conclusion that the forced deportation of Jews from the frontline territories has become a determining factor in limiting the pale of settlement.Purpose. To study the state policy towards the Jewish population of the Russian Empire during the First World War.Objectives: to analyze the political situation that developed during the war on the forced resettlement of Jews deep into Russia, to investigate the factors that influenced the expansion of the pale of settlement.Methodology. The author's methodology is based on the principles of historicism and objectivity. Methods of synthesis and generalization of the obtained data are also used.Results. In the study, the author shows that the First World War contributed to the limitation of the pale of settlement, but Jews, as before, remained the object of discrimination by the authorities. And the war has only worsened their situation. Jewish merchants were blamed for disruptions in the supply of the Russian army, the rights of residents of the frontline territories were severely curtailed, and they were evicted from some regions as potential traitors and spies. Jewish pogroms have become commonplace in the context of the increasing anarchy of Russian society.Conclusion. The analysis of the state policy towards the Jewish population of the Russian Empire led to the conclusion that the war caused a change in the pale of settlement for Jews who were forced to evacuate from the frontline areas. Jewish refugees settled throughout the Russian Empire.

A Simulation of the Biomechanical Behavior of Orthodontic Miniscrews for Infrazygomatic Anchorage: An In Vitro Study

Background: This study aims to investigate the biomechanical characteristics of orthodontic miniscrews manufactured for use in infrazygomatic crests. Methods: This study analyzed the Zygomatic Spider Screw (HDC, Thiene, Italy), considering four variables: length, insertion angle, insertion depth, support thickness. Twenty-two configurations were tested on 66 miniscrews, all with a diameter of 2 mm, and were inserted into D1 bone-like supports. After compression tests, the deformation angles and linear distances between the tips of the miniscrews were measured. Results: Power analysis showed 99% power for the deformation angles and linear distance. The ICC indicated the good repeatability of the results, with values above 0.70. The mean maximum load values ranged from 21.5 N to 228.8 N, while the mean deformations ranged from 0.45 mm to 2.26 mm. Miniscrews with greater insertion depths (6 and 8 mm) exhibited approximately twice the average deformation (1.5 mm) compared to those inserted at 2 and 4 mm (0.71 mm). It was noted that miniscrews with higher deformation and a lower applied load were those with a working part length of 10 mm and an insertion depth of 2 mm, while those with lower deformation and a better load-bearing capacity were those with a working part length of 6 mm that were fully inserted into the bone support. Conclusions: The miniscrew design and insertion depth significantly affect biomechanical properties. It is advisable to maximize the insertion depth and minimize the distance between the support and the point of force application. The insertion angle did not prove to be a determining factor in the load.

PM10 Indoor/Outdoor Air Quality Relationship in School Buildings: A Case Study in Barreiro

This article analyses the relationship between PM10 concentrations inside and outside two schools in Barreiro, Portugal: Primary School No. 5 and D. Luís Mendonça Furtado Basic School. The main objective was to understand the impact of external and internal sources on indoor air quality (IAQ) in school environments. Monitoring campaigns were carried out in different indoor spaces, including classrooms, the gym, and the canteen, and the results were compared with PM10 levels outside the building. At Primary School No. 5, indoor PM10 concentrations were consistently higher than the outdoor values measured on Avenida do Bocage, with an average Indoor/Outdoor (I/O) ratio of 2.2, indicating a significant impact of indoor activities on particle levels. Similarly, at the D. Luís Mendonça Furtado Basic School, there was an increase in PM10 and PM2.5 concentrations during school hours, with the highest I/O ratio (3.04) recorded on school days. In the evenings and at weekends, when the spaces were unoccupied, particle concentrations dropped considerably, reaching an I/O ratio of 0.70. Said results suggest that indoor activities are a determining factor for particle levels in indoor air, emphasizing the need for ventilation and pollution control strategies in schools to protect the health of students and staff.

PENGARUH KEPEMIMPINAN TRANSFORMASIONAL, STRES KERJA, DAN KEPUASAN KERJA TERHADAP TURNOVER INTENTION

Transformational leadership style can increase employee motivation and job satisfaction. Job stress has the potential to decrease employee satisfaction and increase intention to leave the company. Job satisfaction can be a determining factor in retaining employees to remain committed to the organisation. This study aims to analyse the effect of transformational leadership style, job stress, and job satisfaction on turnover intention; as well as the role of stress and job satisfaction as intervening variables. This type of research is quantitative by distributing questionnaires to employees of Public Company Jasa Tirta I, with a sample of 109 people. Regression test to see the direct effect between variables and mediation test to determine the role of job satisfaction and job stress in mediating the effect of transformational leadership on turnover intention. The results showed that transformational leadership style has a positive effect on job satisfaction and a negative effect on turnover intention. Job stress has a positive effect on turnover intention, while job satisfaction has a negative effect on turnover intention. Job satisfaction and job stress act as significant mediating variables in the influence between transformational leadership and turnover intention. The implication of this study is that companies need to implement effective transformational leadership to increase job satisfaction and reduce turnover intention. Good management of job stress is necessary to retain employees in the long term.

Workers’ Perspectives on an Unjust Transition: Place, History, and Workplace Closure at Grangemouth Oil Refinery, Scotland

AbstractFossil fuel workers are central protagonists in achieving a “just transition” to a greener and fairer economy. This article examines workforce attitudes towards transition, redundancy, and restructuring following Petroineos’ announcement that the Grangemouth oil refinery in Scotland would close by 2025. It analyses interviews with workers recorded as they responded to the announcement, but before closure processes had begun. A labour‐centred view of just transition predominated among our respondents, in response to a closure process where capital's agency was the determining factor. Worker narratives were strongly embedded in history and place through Grangemouth's longstanding status as a key oil and chemicals hub. Perspectives on justice moulded across procedural and distributional facets, centred on local employment, but extended also to the reparative through a commitment to avoiding replicating prior waves of deindustrialisation. Fundamentally, a just transition meant applying workers’ skills locally to meet the imperatives posed by climate change.

Determinants of children’s nutritional status in rural and urban areas of West Java, Indonesia

Introduction: Children’s nutritional status is a vital indicator of public health and national development. Sufficient nutrition during early childhood is crucial for supporting physical growth, neural development, and cognitive performance. A well-nourished population serves as the foundation of a productive workforce, contributing significantly to a nation’s sustainable economic growth. Maternal education plays a crucial role in determining children’s nutritional status, alongside the quality and adequacy of children’s dietary intake. Objectives: This study primarily aims to identify nutrients intake, nutritional status, and determinants of children’s nutritional status in both rural and urban areas of West Java, Indonesia. Methods: This research employed a cross-sectional design, involving a sample of 150 households with children under five in rural areas (Cianjur Regency) and 150 households in urban areas (Sukabumi City), both located in West Java. This study collected primary data from interviews using questionnaires and anthropometric measurements. Results: The adequacy level of energy and fat is almost 100%. Adequacy levels of protein is above 100% or have far exceeded their needs. All of the micronutrients did not meet the adequacy. As many as 19% of children were underweight (18.6% in rural and 19.4% in urban), 4.3% wasting (2.7% in rural and 6.0% in urban), and 32% stunting (33.4% in rural and 30.7% in urban). The prevalence of children at risk of being overweight in urban areas was 8.7% and in rural areas was 6.7%. The determinant of children’s nutritional status was mother’s education. Conclusion: All of micronutrients did not meet the adequacy in both rural and urban areas. The results of this study indicate that prevalence of chronic malnutrition was still high in both rural and urban areas. Mother’s education was the determinant factor of children nutritional status.

Effect of tibialis anterior focal muscle vibration for gait rehabilitation in hemiplegic individuals during the subacute phase after stroke: the NEUROVIB-AVC study protocol - a multicentric randomised controlled trial.

Gait recovery remains one of the most determining factors in social participation for poststroke individuals, in whom ankle dorsiflexor function is closely related to gait speed. Focal muscle vibration has shown promising neurophysiological and clinical effects in neuromotor recovery. However, it remains to be determined whether tibialis anterior focal muscle vibration applied to the paretic limb could improve walking speed when implemented in early rehabilitation after stroke occurrence. This study describes a multicentric randomised controlled trial in which 70 participants will be randomly assigned in a 1:1 ratio to the tibialis anterior focal muscle vibration group or the sham group, in addition to their conventional rehabilitation. Participants will receive 100 Hz vibration/sham for 30 min, five times per week, for 8 weeks. The primary outcome will be gait speed, as assessed through a 10 m walking test and will be compared between groups at the end of the intervention. Secondary outcomes will include gait abilities, neuromuscular clinical evaluations and neurophysiological measures. Outcomes will be assessed at baseline and across five visits during and after the intervention, until 16 weeks of follow-up. Ethics approval was obtained from the French Ethics Committee 'Protection des Personnes Nord Ouest III' in 30 May 2023 (IDRCB: 2023-A00489-36). The results will be published in a peer-reviewed journal and presented at scientific conferences. NCT05945212.

Impact of Sarcopenia on Mortality in Patients Undergoing TAVI: A Follow-Up Study

Objective: The use of transcatheter aortic valve implantation (TAVI) has expanded in patients with severe aortic stenosis who are deemed inoperable. However, sarcopenia may be a determining factor in their survival. The aim of our study is to assess the impact of sarcopenia, evaluated by computed tomography (CT), on mortality in this patient population. Methods: Patients with severe aortic stenosis undergoing follow-up after TAVI at Hospital Universitario de la Princesa were recruited. Body composition was analyzed using routine CT scans and open-source software. Survival analysis was performed, and correlations between body composition parameters at the T12 and L3 vertebral levels were assessed. Results: Our sample comprised 97 subjects. Time to mortality was associated with diabetes mellitus (p = 0.050), atrial fibrillation (p = 0.02), and respiratory disease (p = 0.03). Interestingly, sarcopenia (p = 0.039) and normal-density muscle area (p = 0.025) were also associated with time to mortality, with the association between sarcopenia and time to mortality becoming stronger after adjusting for covariates (p < 0.001). The correlation between different body composition parameters at the T12 and L3 vertebral levels was substantial and statistically significant. Conclusions: The use of CT to assess sarcopenia in patients with severe aortic stenosis undergoing TAVI is highly valuable and can predict time to mortality. Sarcopenia should be considered as a relevant parameter in the comprehensive evaluation of these patients.

Data-driven machine learning algorithm model for pneumonia prediction and determinant factor stratification among children aged 6–23 months in Ethiopia

IntroductionPneumonia is the leading cause of child morbidity and mortality and accounts for 5.6 million under-five child deaths. Pneumonia has a significant impact on the quality of life, the country's economy, and the survival of children. Therefore, this study aimed to develop data-driven predictive model using machine learning algorithms to predict pneumonia and stratify the determinant factors among children aged 6–23 months in Ethiopia.MethodsA total of 2035 samples of children were used from the 2016 Ethiopian Demographic and Health Survey dataset. Jupyter Notebook from Anaconda Navigators was used for data management and analysis. Important libraries such as Pandas, Seaborn, and Numpy were imported from Python. The data was pre-processed into a training and testing dataset with a 4:1 ratio, and tenfold cross-validation was used to reduce bias and enhance the models’ performance. Six machine learning algorithms were used for model building and comparison, and confusion matrix elements were used to evaluate the performance of each algorithm. Principal component analysis and heatmap function were used for correlation detection between features. Feature importance score was used to identify and stratify the most important predictors of pneumonia.ResultsFrom 2035 total samples, 16.6%, 20.1%, and 24.2% of children had short rapid breath, fever, and cough respectively. The overall magnitude of pneumonia among children aged 6–23 months was 31.3% based on the 2016 EDHS report. A random forest algorithm is the relatively best performance model to predict pneumonia and stratify its determinates with 91.3% accuracy. The health facility visits, child sex, initiation of breastfeeding, birth interval, birth weight, husbands’ education, women’s age, and region, are the top eight important predictors of pneumonia among children with important scores of more than 5% to 20% respectively.ConclusionsRandom forest is the best model to predict pneumonia and stratify its determinant factors. The implications of this study are profound for advanced research methodology, tailored to promote effective health interventions such as lifestyle modification and behavioral intervention, based on individuals’ unique features, specifically for stakeholders to take proactive childcare interventions. The study would serve as pioneering evidence for future research, and researchers are recommended to use deep learning algorithms to enhance prediction accuracy.

Gender discrimination and its impacts on women’s empowerment in the development process in Boajibu, Simbaru Chiefdom, Kenema District

Gender discrimination is the manifestation of unequal treatment towards individuals based on their gender. This insidious issue significantly impacts human lives, especially when opportunities are unjustly denied due to one's gender. It is distressing to witness such discrimination persist in our society, as gender should never be a determining factor for one's access to opportunities. Regrettably, women continue to face egregious discrimination, impeding their empowerment. This study delves into the pervasive problem of gender discrimination and its adverse effects on women's empowerment globally. By examining the plight of discriminated women in our society, particularly in rural areas, this research sheds light on the entrenched biases that prevail. The prevalent discriminatory attitudes are evident, especially towards girl children, perpetuating inequality. Employing a quantitative research approach and utilizing a questionnaire for data collection, this study underscores the enduring presence of gender discrimination in our society. Women bear the brunt of this discrimination, particularly in rural settings, where it severely hampers their access to basic education. Addressing the fundamental issue of inequality necessitates a shift in societal perspectives to eradicate gender discrimination comprehensively.

Personal experience with abortion: a determining factor in Physician's attitudes towards abortion

Personal experience with abortion: a determining factor in Physician's attitudes towards abortion

Hypercholesterolemia and cardiovascular disease: the dilemma of effective treatment for target achievement according to guidelines and national healthcare policies and a call to action.

The burden of cardiovascular disease (CVD) remains a worldwide challenge. CVDs, in particular atherosclerotic CVD, are still an important cause of mortality and morbidity. The increase in life expectancy is a further determining factor in the epidemiology of CVDs in some countries, such as Italy, which increases the urgency of intervening on modifiable risk factors. Among these, hypercholesterolemia is present in a significant percentage of CVD patients. A linear relationship between the risk of acute events and the plasma level of low-density lipoproteins cholesterol (LDL-C) is well known. The reduction of LDL-C levels leads to a decrease in mortality and morbidity. The overall recommendation is to treat hypercholesterolemia intensively and as early as possible. Statins, ezetimibe, bempedoic acid, pro-protein convertase subtilisin/kexin 9 inhibitors (i.e., the monoclonal antibodies alirocumab and evolocumab, or the small interfering RNA inclisiran) are all available for reaching LDL-C targets according to risk profile. While the real-world data confirm the safety of currently recommended LDL-C targets, data on their actual achievement are discouraging, less than half of patients on therapy reach the LDL-C targets recommended by the most recent ESC/EAS Guidelines. The causes of this critical discrepancy are multiple, arising from the various components that characterize the complex relationship between patient and physician within the healthcare system. A call to action is needed. Doctors should be continuously updated on the latest evidence, follow recommendations and engage the patient in the therapeutic process. Regular monitoring of the effects of the prescribed therapy, also through e-health and telemedicine tools, is essential, as well as changing therapy when LDL-C is not adequately controlled. Finally, health systems should align with guidelines and promote good clinical practices, overcoming a silo system, to impact outcomes in terms of overall sustainability.

INFLUENCE OF WORK ENGAGEMENT ON THE RELATIONSHIP BETWEEN PSYCHOLOGICAL CAPITAL AND MANAGERIAL PERFORMANCE OF CONTROLLERS

This study evaluated the influence of work engagement on the relationship between psychological capital and managerial performance of 166 controllers working in the budgetary context of different industrial organizations in Brazil. The results show that psychological capital, through the psychological capacities of self-efficacy, hope, optimism and resilience, acts as a potentiating element of work engagement, positively reflecting on the controllers' vigor, dedication and absorption in their work. The interaction between these variables is a determining factor in raising managerial performance. The results show that organizations that promote controllers' psychological capital and their work engagement are more likely to raise managerial performance. Keywords: Psychological capital; Work engagement; Managerial performance; Controllers.

ANALYSIS OF CLASSROOM SPACE REQUIREMENTS FOR ELEMENTARY SCHOOLS BASED ON THE PROJECTION OF SCHOOL-AGE POPULATION GROWTH IN SURABAYA CITY (STUDY ON EDUCATIONAL PLANNING USING THE SOCIAL DEMAND METHOD)

This study aims to describe and analyze the classroom space requirements for elementary schools based on the projection of school-age population growth and to compare it with the School Minimum Service Standards (SPMP) and National Standards for Education (SNP). The research conducted is a descriptive qualitative study with projection calculations. This method is expected to yield actual data from several years ago and the present, which will then be estimated to predict trends for the coming years. In data collection, this study utilizes data on the number of school-age children (7-12 years) in Surabaya City. This data is obtained from demographic sources such as the Central Statistics Agency (BPS) and population projections based on age groups. The data collection technique employs secondary data sources through documentation studies. The data analysis technique involves data collection, data input, and data processing using projection methods with a mathematical equations approach. The results of the study indicate that the growth of the school-age population is a determining factor in the need for classroom space, which underscores the necessity for strategic planning in educational infrastructure to ensure that all children have access to adequate learning environments.

Investigation of the effect of DBD plasma treatment on the surface properties of polylactic acid layers prepared with different mass percentage of polylactic acid/chloroform solution

AbstractPolylactic acid (PLA) is a biodegradable polymer that has gained prominence as a functional material, particularly in the form of thin films used in industries like food packaging. These films are typically applied by melting, but this method is unsuitable for heat‐sensitive surfaces. This study investigates the use of a plasma dielectric barrier discharge system (DBD) to modify PLA films prepared from a PLA–chloroform solution at 5, 10, and 15 mass percentage concentrations (% w/v). To evaluate the surface properties of the PLA films, contact angle measurements, surface energy assessments, atomic force microscopy (AFM), and Fourier‐transform infrared spectroscopy (FTIR) were conducted. Contact angle measurements revealed a dramatic decrease in the contact angle, from 75 ± 0.18° for untreated films to 28.7° for plasma‐treated films at 15% PLA concentration. FTIR analysis confirmed an increase in the intensity of some peaks related to polar oxygenated functional groups, particularly hydroxyl (‐OH) and carbonyl (C=O) groups. Atomic force microscopy analysis reveals a needle‐shaped surface morphology after plasma treating, that is, increased roughness and surface area. Surface energy analysis showed a reduction in the dispersive component of surface energy but an overall increase in total surface energy; specifically, the polar component of surface energy increased by 45% at 15% PLA concentration compared to untreated films. When comparing the results obtained in the present study with those from a recent work that used a non‐polar solvent (toluene), the polarity of the solvent could be a determining factor in the polymer films with different concentration obtained through solution deposition, which is affected by plasma. This could serve as a starting point for further investigations in this area. Overall, plasma treatment proved effective in modifying PLA films on heat‐sensitive substrates, enhancing hydrophilicity, particularly at higher PLA solution concentrations prior to casting a thin film.Highlights PLA–chloroform solutions with different concentrations were prepared. PLA–chloroform films were spin‐coated and treated with DBD plasma. Contact angle, surface energy measurement, AFM, and FTIR analysis were conducted. PLA films with higher concentration were more impacted by plasma treatment. Concentration and solvents polarity impact the hydrophilicity and roughness of treated PLA films.

Proteomics-Based Investigation of Sexual Dimorphism in Swim Bladder Texture of Chu’s Croaker (Nibea coibor)

The swim bladder of Chu’s croaker (Nibea coibor) is an expensive food with high texture requirements. In this study, we found that male swim bladder had better toughness than female. To explore the main determining factor affecting texture properties of swim bladder, a comparison of proximate composition, collagen microstructure, and proteomics was carried out between male and female swim bladders. Results indicated that it should be collagen microstructure mainly affecting the texture characteristics of swim bladder, rather than the composition. The collagen fibers in male swim bladder were significantly more uniform and regular than female. By proteomics analysis, it was further discovered that collagen XII was the most significantly up-regulated protein in the male swim bladder and may be crucial in morphology of collagen fibers. In summary, collagen XII was identified to be a potential key molecule affecting the texture of the swim bladder, mainly through regulating properties of collagen fibers. This study contributes to a deeper understanding of the structural characteristics of swim bladder collagen and provides critical molecular targets for the regulation of texture in swim bladder.
