Honey is a functional food used in traditional medicine to treat numerous human ailments. The health-promoting properties of honey depend on its physicochemical characteristics, chemical composition, and antioxidant potential, which result from the botanical and geographical origin of honey. In this study, the physicochemical properties, antioxidant and antimicrobial potential of seven honey samples from the Nišava region were analyzed. The honeydew sample had the highest content of phenols and flavonoids and the best scavenging and antimicrobial activities (MIC 6.25-25%). The content of flavonoids was also high in meadow honey, which demonstrated excellent scavenging activity against the DPPH radical. Acacia and lavender honey samples showed good antibacterial activity (MIC 12.5-25%), but only honeydew inhibited the growth of yeast Canida albicans (MIC 12.5%). The results presented in this paper revealed differences in the biological activity of honey samples, indicating the necessity of analyzing each honey sample individually before using it as a functional food.

En el momento de convulsión social que vivimos, deseamos conocer, que hacer para salir de esta gran crisis: en la familia, en la vía pública, en las escuelas, en el trabajo, crisis en las instituciones del estado y en general, crisis en todo el país. En la época de nuestros padres cuando nos portábamos mal en casa, recibíamos un castigo, un chicote de tres puntas colgado en un lugar visible de la sala era suficiente y en el colegio, reglazos en las manos o sentados contra la pared en la esquina hasta que termine la clase, la misma que se completaba en casa porque nuestros padres nos reprendían cuando nos llamaban la atención en el colegio, reconociendo así la sólida estructura del sistema familiar y la asignación de autoridad al maestro para que puedan corregir a nuestros hijos manteniendo una adecuada disciplina en la aulas. Con el nuevo sistema legal instituido en el país, es imposible sancionar a un niño, los mecanismos de protección implementados (específicamente el código del niño y el adolescente), el maestro en el colegio solo debe centrarse en el proceso pedagógico, porque no cuenta con procedimientos correctivos para modificar la conducta violenta de los estudiantes, la indisciplina, la falta de interés en el logro de los aprendizajes o simplemente el incumplimiento de las tareas escolares, y esta situación tocada únicamente de manera ejemplarizadora se replica en todos los estratos sociales y todos los sistemas del sociales hasta llegar al contexto nacional. En el siglo XVIII Jeremy Bentham[1] expresó la idea de constituir un postulado carcelario como un sistema de “Control Social” relacionado al ámbito laboral, educativo o de corrección ciudadana; en la búsqueda de redefinir o corregir los comportamientos humanos y de adaptación a los criterios culturales de la sociedad, grupo u organización; debiendo existir relaciones de mando y obediencia entre personas; la presente investigación busca reconocer un marco introductorio del control social en el país, reconociendo su existencia, comportamiento, avances y retrocesos así como la factibilidad de su refundación en el contexto actual, control social en todos los estratos sociales, control social para las autoridades desde la presidencia de la república hasta el último empleado del estado, control social para el delincuente, protección para el ciudadano, y un adecuado comportamiento de las autoridades y de todos los ciudadanos en cada contexto social donde nos ubicamos en cualquier momento.

Childhood, particularly toddlerhood, is a period of rapid growth. Feeding difficulties are a common challenge faced by most parents, which can lead to nutritional deficiencies in children. One approach to improving children's dietary habits, with the goal of enhancing community nutrition, especially for toddlers, is to utilize local food ingredients in the form of alternative complementary foods. This study focused on Bole Mortel, a traditional food with a specially formulated recipe for toddlers aged 12-59 months. This research employed functional foods based on local ingredients, namely catfish, soybean tempeh, chicken, and carrots, as the primary raw materials. The study utilized a quantitative approach with an experimental design, employing a Completely Randomized Design (CRD) to assess the impact of catfish and soybean tempeh substitution on the nutritional quality, protein quality, and organoleptic properties of Bole Mortel. The study involved one factor, catfish and tempeh substitution with four different formulations. Each formulation was evaluated for preference by 30 semi-trained panelists and subjected to a descriptive analysis by 10 trained panelists. The results demonstrated that the nutritional quality of Bole Mortel in each formulation met 10-15% of the nutritional requirements for children aged 12-59 months. Theoretical digestibility and Net Protein Utilization for all formulations >90%. Moreover, the amino acid score for all formulations was 100. The proportion of catfish and soybean tempeh did not significantly influence taste, aroma, color, or texture. The P3 formulation, with a catfish : soybean tempeh ratio of 30:70, exhibited the highest preference and was deemed the most suitable. Toddlers aged 12-23 months can consume 60 grams (approximately 4-5 pieces) of Bole Mortel, while those aged 25-59 months can consume 80 grams (approximately 6-7 pieces). These serving sizes can fulfill 10-15% of a toddler's daily nutritional needs according to age, as outlined in the 2023 Technical Instructions for Providing Additional Food.

Denture stomatitis is a common oral health problem in denture users. It can occur due to fungal infections caused by C. albicans. An effervescent tablet is a chemical denture cleanser that can reduce plaque and microorganism accumulation, including C. albicans. The addition of natural ingredients such as cocoa pod husk extract, which contains chemical compounds like flavonoids, saponins, and tannins, has shown antifungal activity against microorganisms such as C. albicans. This research aims to determine the effect of cocoa pod husk (Theobroma cacao L.) effervescent tablets in inhibiting the growth of C. albicans after a 15-minute soaking period. The treatment groups were effervescent tablets containing cocoa pod husk extract at concentrations of 20% and 25%, polident and aquadest. The samples were thermoplastic nylon discs with a diameter of 10 mm and a thickness of 2 mm. The discs were immersed in the treatment solutions for 15 minutes and vibrated for 30 seconds using vortex, spreading 0,1ml Saboraud Dextrose Broth (SDB) on Saboraud Dextrose Agar (SDA) and incubated for 48 hours at 37°C. The number of C. albicans colonies grown on the SDA medium was counted using a colony counter. The results showed that the cocoa pod husk effervescent tablets with 25% concentration were more effective than the 20% concentration, with average colony counts of 231.8 and 372.6, respectively. The highest average C. albicans colony count was observed in the negative control group (694.8), while the lowest was in the positive control group (0). Based on the results effervescent tablets containing cocoa pod husk extract as a denture cleanser are effective in inhibiting the growth of C. albicans.

The global rollout of COVID-19 vaccines has been a significant step in controlling the SARS-CoV-2 pandemic. While the vaccines have proven to be generally safe, adverse reactions, including both local and systemic effects, have been observed. Cutaneous manifestations, though rare, have been reported in some instances.

We report the case of a 67-year-old male who developed pruritic erythematous-to-violaceous papules and plaques three days after receiving the second dose of a COVID-19 vaccine. The lesions were found on the right inner thigh, forearms, trunk, and neck. Histopathological examination revealed findings consistent with a lichenoid drug eruption (LDE), a condition typically linked to medications or, in rarer cases, vaccines.

Lichenoid drug eruptions are often seen in association with certain medications, and less commonly with Hepatitis B vaccination. However, this case presents an uncommon presentation of LDE following COVID-19 vaccination, with an atypical distribution of lesions, involvement of uncommon sites, and no history of prior drug or vaccine hypersensitivity.

This case underscores the importance of recognizing rare or atypical skin manifestations, such as lichenoid drug eruptions, as potential vaccine-related adverse effects. Identifying these conditions allows clinicians to ensure accurate diagnosis and appropriate management.

Published: February 2025

This study provides an understanding of stress and how it is associated with mental health which often affects lecturers in the Universities. Globally, mental health is recognized as an issue of interest because it cuts across all gender, ages, races, social class among others. People with mental health conditions ranging from depression, anxiety and mood disorders face stigmatization and discrimination in the educational institutions, health care and employment. Studies have shown that people believe mental health issues have been caused by punishment from God, black magic, sin inherited from parents among others which often leads to shame, guilt and concealing the mental health issue further exacerbating the problem. This study therefore provides an understanding of how the mental health affects lecturers and how it interferes with their productivity at the work place. The study is qualitative in nature and 20 respondents who were based in Universities in Eldoret Town were Interviewed. The methods of sampling used were purposive and snowball sampling. The study was analyzed by use of narratives and the emerging themes were family problems, extra workload, unconducive working environment, financial constraints and delayed promotions. The results obtained will add to theoretical knowledge and may help in policy formulation of mental health.

Purpose: Low physical activity leads to muscle atrophy due to lack of exercise time and sport facilities. Addressing this issue, there are alternative methods with shorter training time and less equipment to induce muscle hypertrophy which are neuromuscular electrical stimulation (NMES) Russian protocol and modified hybrid training. We analyzed the difference in muscle hypertrophy of quadriceps and hamstrings between these two methodes in untrained healthy subjects.
Methods: This study was an experimental study on 22 untrained healthy men aged 18-40 which were randomly assigned to the hybrid and NMES group. There were 11 people in each group undergoing the intervention three times a week for 4 weeks. At the beginning and end of the intervention, muscle thickness was measured by B-Mode ultrasonography. The results were compared between groups.
Results: There was a significant increase in muscle hypertrophy in the hybrid group, which are quadriceps (dominant leg p=0.019, non-dominant leg p=0.007) and hamstrings (dominant leg p = 0.013, non-dominant leg p= 0,002). In the NMES group, a significant increase was found in the quadriceps muscle (dominant leg p=0.011, non-dominant leg p=0.002). There was a significant difference in the change of hamstring muscle thickness on the non-dominant leg (p=0.004) between the two groups.
Conclusion: Modified hybrid training and NMES Russian protocol were shown to increase quadriceps and hamstring hypertrophy after 4 weeks intervention. In addition, modified hybrid training was shown to increase non-dominant side hamstring muscle hypertrophy greater than NMES Russian protocol.

Introduction: Managing soccer clubs is a challenging and rewarding experience, requiring a combination of leadership skills and strategic decision-making.
Objective: This study investigated professional soccer club performance determinants in the Ethiopian Premier League. Methodology: This study investigated professional soccer club performance determinants in the Ethiopian Premier League. A correlational analysis was conducted to examine the relationship between the variables and the performance of soccer clubs. Thirty-nine seven-point Likert scale questionnaires, deemed reliable (α = .91), were used to collect data from a sample of 214 participants selected through a simple random sampling method. Frequencies, percentages, means, standard deviations, correlations, and multiple linear regression analyses (with a significance level of P < 0.05) were performed using SPSS version 26 software.
Results: There was a negative correlation between the performance of soccer clubs and fan influence (r = (214) -.170, p < .05); financing (r = (214) -.394, p < .01); club history (r = (214) -.106, p > .05); game situations (r = (214) -.480, p < .01); human capital (r = (214) -.024, p > .05); media (r = (214) -.365, p < .01); legal issues (r = (214) -.406, p < .01); and leadership and governance (r = (214) -.139, p < .05), respectively. Furthermore, eight predictors collectively explained 44.7% of the variance (F (8, 214) = 22.537, p < .001).
Discussion: The study reveals that factors like financing, game situations, media, and legal issues significantly influence soccer club performance, accounting for nearly half of its variability.
Conclusions: The study found that game situation, financial capability, and legal issues significantly impact football club performance, whereas human capital, fan influence, and club history exhibit greater variability.

Authors: Triwiyanto Wahyudi , Rokhman Fathur , Sutarto Joko , Suminar Tri
Published: February 2025

Objective: This study aims to analyze the influence of leadership and meaningful work on teacher well-being and examine the role of teacher self-efficacy as a mediator and organizational climate support as a moderator.
Methodology: This study used a quantitative research approach with an exploratory design. The subject was 210 teachers taken from six residencies in Central Java using random cluster sampling techniques. Data were analyzed using the Structural Equation Modeling technique based on variance, namely Partial Least Square.
Results: The results of this study reveal several significant findings. First, teacher-leaders, teacher-meaningful work, and self-efficacy positively and significantly influence honorary teachers’ well-being. Second, teacher-leaders and teachers’ meaningful work positively and substantially influences self-efficacy. Third, teacher-leaders and teachers’ meaningful work positively and significantly influence honorary teachers’ well-being through teacher self-efficacy. Fourth, the supportive organization climate does not mediate teacher-leader and teacher-meaningful work on honorary teacher well-being.
Discussion: The discussion are: First, the change in teacher-leader, teacher-meaningful work, and self-efficacy is directly proportional to honorary teachers’ well-being. Second, the change in teacher-leader and teacher-meaningful work is directly proportional to the self-efficacy of honorary teachers. Third, increasing teacher-leader and teacher-meaningful work will be more effective in improving teachers’ well-being if they strengthen teachers’ self-efficacy. Fourth, interventions or changes designed to enhance teacher leadership will have the same effect on teacher well-being regardless of the variation of the supportive organizational climate.
Conclusions: The implication is that no single variable determines the well-being of honorary teachers without involving other variables as a practical, non-financial approach.

Arsitektur VGG-16 dipilih karena kemampuannya dalam mengekstraksi fitur detail melalui lapisan konvolusional bertingkat. Dataset yang digunakan berisi 910 citra, dibagi menjadi tiga kategori, dan diolah menggunakan VGG-16 untuk menghasilkan vektor fitur berdimensi 4096. Klasifikasi dilakukan dengan jaringan saraf tiruan yang memiliki tiga lapisan tersembunyi, dan evaluasi model menggunakan metode 10-fold cross-validation. Metrik yang digunakan untuk menilai kinerja model adalah akurasi, presisi, dan recall. Hasil penelitian menunjukkan bahwa VGG-16 mampu mengklasifikasikan citra dengan akurasi sebesar 96,48%, dengan performa terbaik pada kelas Berawan, Cerah, dan Terbit, yaitu masing-masing 96%, 95,5%, dan 97,2%. Meskipun model menunjukkan akurasi tinggi, tantangan masih ada dalam membedakan citra dengan fitur visual yang serupa, seperti intensitas cahaya dan formasi awan. Kesimpulannya, VGG-16 efektif dalam klasifikasi kondisi cuaca berbasis citra digital, namun memerlukan pengembangan lebih lanjut untuk mengatasi kesalahan klasifikasi akibat kemiripan visual antara kategori cuaca

Published: February 2025

The research is intended to analyse the effects of women's migration on themselves and their families, focusing on the balance between opportunities and risks. It intends to identify the main reasons why Burundian women are migrating to the Middle East, and to explore the positive and negative socio-economic impacts of their migration. This study was carried out using a qualitative method based on thematic content analysis of the life stories of migrant women back to Burundi.

The research results show that Burundian women migrate mainly because of poverty, need for business assets and employment, housing problems, avoidance of stigma, low wages and search for autonomy. This migration has positive impacts such as the acquisition of business assets, land purchase housing self-construction, financial support for families remaining in Burundi, economic empowerment of migrant women, and education of children. However, the negative impacts include the poor living conditions and health problems of children, hard working conditions, difficulties related to family separation, and stigmatization.

Solar energy is popular worldwide due to the escalating demand for renewable and clean energy solutions. The inherent low power conversion efficiency of solar panels highlights the indispensable role of a solar charge controller in optimizing the power transfers from the solar panel to a storage battery. Traditional buck converters are marred by considerable power losses due to freewheeling diodes, thus making a synchronous buck converter, which necessitates protection against the reverse current from the battery to the solar panel. During low irradiation, the solar panel voltage typically falls below the battery voltage, creating the potential for reverse current flow, which may cause damage to other system components. This study proposes an innovative current backflow protection circuit, effectively addressing reverse polarity risks, demonstrated through LTspice simulations. Utilizing an NMOS MOSFET, this circuit disrupts the connection whenever solar panel voltage falls beneath a predefined cutoff value, thereby preventing reverse current damage. The protective mechanism’s efficacy is validated by monitoring the NMOS MOSFET’s drain current, which remains at 0A below the cutoff voltage but transitions to negative values above it, indicating a reverse flow and underscoring the circuit’s reliability in safeguarding solar energy systems.

Objectives: The purpose of the present study is to show the biomechanical and histological alterations in the calcaneal tendon of rats submitted to stresses through physical exercise and heating in a thermal bath. Methods: We used 35 rats divided into seven groups: Baseline (BL), group not submitted to any intervention, (C), group not submitted to either heating or exercise, (Ex), group with no heating and with exercise, (H42), group with heating at 42°C and without exercise, (ExH42), group with heating at 42°C and with exercise, (H45), group with heating at 45°C and without exercise, and (ExH45), group with heating at 45°C and with exercise. The exercises consisted of water jumps performed 10 times in 4 sets, interspersed with the thermal bath. Heating was performed by immersing the lower limbs in warm water for 10 minutes.
The tendons were removed and submitted to the traction test, histological analysis, and quantification by means of fractal analysis. Statistical analysis was performed, with a significance level of 5%. Results: Heating at 45°C significantly decreased maximum strength, stiffness, energy absorbed, and mature collagen (p<0.05), and simultaneously increased the amount of immature collagen (p<0.05). Heating and exercise promoted inflammation and disarrangement of tendinous tissue. Conclusion: We conclude that heating to 45°C caused injury and a decrease in mature collagen, leading to weakening of the biomechanical properties. In addition,exercise also caused tendon damage and intensified the effects of heating.
