Authors: Oré Acevedo Juan Francisco , Urteaga Quiroga Rosmery , Castillo Chávez Katerin Carmen
Published: November 2024

La hipoplasia mandibular bilateral es la causa más frecuente de obstrucción de las vías aéreas y puede producir dificultad respiratoria y digestiva. Para su resolución, usualmente se requiere realizar una distracción osteogénica mandibular, que permite incrementar la distancia anteroposterior de la mandíbula. El objetivo de este estudio fue describir las experiencias de un instituto pediátrico especializado ubicado en Lima, Perú, en la aplicación de distracción osteogénica para recuperar la función de las vías respiratorias y del tracto digestivo. Se recopiló información sociodemográfica y clínica (pre y postoperatoria) de pacientes sometidos a  distracciónmandibular bilateral entre el 2016 y el 2022. Se incluyeron un total de 17 pacientes. El 53 % de los casos tuvieron edades entre 1 y 11 meses. Todos los pacientes permanecieron en la Unidad de Cuidados Intensivos, requiriendo el 58,8 % (9/17) intubación orotraqueal y el 41,2 % (8/17) traqueostomía. Como resultado de la intervención, se produjeron mejoras anatómicas y funcionales de las vías respiratorias y digestivas, mediante el aumento mandibular anteroposterior. Los hallazgos sugieren que la distracción osteogénica es una técnica útil para el manejo de la obstrucción de las vías aéreas causada por hipoplasia mandibular en la edad pediátrica.

Authors: Ramírez Espinoza Alberto
Published: November 2024

Los quistes aracnoideos de la cisterna cuadrigeminal (QACC) representan un grupo poco frecuente de lesiones del sistema nervioso central. El cuadro clínico depende de la extensión del quiste y de la severidad de la compresión. Se realizó una revisión retrospectiva de los casos con diagnóstico de QACC intervenidos quirúrgicamente en el Instituto Nacional de Salud del Niño San Borja en el periodo  2017-2024. Se recopilaron datos sociodemográficos y clínicos de los pacientes a partir de las historias clínicas. Durante el periodo de estudio, 10 pacientes diagnosticados con QACC fueron intervenidos quirúrgicamente. Cinco pacientes presentaron QACC tipo I y cinco tipo III. El 80 % de los casos recibió una neuroendoscopia con fenestración del quiste. El 70 % de pacientes requirió solo una cirugía. El 50 % de los pacientes quedaron libres de cualquier forma de derivación del líquido cefalorraquídeo. En nueve pacientes, se observó disminución del tamaño del quiste; mientras que en el caso restante, la resolución completa de la lesión luego de dos cirugías. En esta serie de casos, la aplicación de la neuroendoscopia con fenestración del quiste demostró una mejoría en el cuadro clínico de los QACC, así como una disminución del tamaño o resolución del quiste.

Ciertas situaciones en la infancia, como el castigo físico y la violencia de pareja en el hogar, pueden afectar la salud dental de los niños, lo cual puede desencadenar en el desarrollo de enfermedades estomatológicas y estrés psicológico. El objetivo de este estudio fue evaluar la asociación entre el castigo físico y la exposición a violencia física de pareja con el cepillado dental adecuado en niños peruanos menores de 5 años, a través de un análisis de datos secundarios de la Encuesta Demográfica y de Salud Familiar 2021. La asociación se evaluó mediante modelos lineales generalizados de la familia Poisson y función de enlace logarítmica. Los resultados se presentaron en razones de prevalencia (RP). La prevalencia de cepillado dental adecuado fue del 22,8 %. La prevalencia de cepillado dental adecuado fue 20 % menor en niños de madres que reportaron haber sido víctimas de violencia por su pareja, sin que sus hijos lo hayan presenciado, en comparación con aquellos cuyas madres no reportaron ser víctimas de violencia (RP = 0,80; IC 95 % = 0,71 a 0,91; p < 0,001). Asimismo, se observó una prevalencia 17 % mayor de cepillado dental adecuado en aquellos niños que recibieron palmadas como castigo físico de su padre o madre en comparación con aquellos que no recibieron castigo físico (RP = 1,17; IC 95 % = 1,05 a 1,31; p = 0,006). Los hallazgos de este estudio sugieren la necesidad de incluir la violencia de pareja entre los factores potencialmente relacionados con el cepillado dental inadecuado.

Cell membranes always respond to electric fields because cell membranes consist of ions and molecules. For many years, the technique of inducing electric pulses into the cell to increase its permeability has been investigated. When rectangular pulses with a train of high voltage (about 1000 V/cm) and low repetition frequency (about 1 Hz) are applied, patients feel an unpleasant sensation, while electroporation (EP) using higher repetition frequency and low voltage (HFLV) has been shown to have a higher inhibition of tumor growth. The current study aimed to predict synergism between EP and Bleomycin (SEPB) affecting K562 and MIA-PACA2 cancer cells and to optimize repetition frequency and electric pulse amplitude for HFLV EP by sampling a wide variety of different sets of pulse specifications on SEPB. Both cell types were exposed to higher frequency (4-6 kHz) and low voltage (50–150 V/cm). The characteristics of electric pulses that generate effective synergism with a small dose of Bleomycin were determined. As an output of the applied electric pulses with arbitrary frequency and voltage, the resulting synergism can be achieved using a theoretical model based on an adaptive neuro-fuzzy inference system (ANFIS). Results showed a significant correlation between experimentally observed and theoretically predicted data regarding the calculated coefficient of determination (R2 = 0.99 for K562 and 0.86 for the MIA-PACA2 cell type). It is concluded that this model is intensely reliable for prediction. This suggests that the model is valid and can calculate the SEPB that is affected by the magnitude of the electric pulse and the repetition frequency. Applying the prior experimental results to future drug delivery or biophysical applications might suggest this approach as a time and resource-saving alternative to conducting more tests.
Diagnostic Methods and Outcomes of Clostridial Necrotizing Enterocolitis in Preterm Infants: A Retrospective Study
Authors: Haddad Hanady Al , Borrhomee Suzanne
Published: November 2024

Background: Necrotizing enterocolitis (NEC) is the most severe and life-threatening gastrointestinal disease among preterm infants.
Objective: We evaluated the diagnostic methods for clostridial NEC in our center. We described the affected population, the feeding strategies used before the onset of NEC, the clinical outcomes of patients with clostridial NEC and the outbreak of clostridial NEC in our center.
Design: We performed a retrospective monocentric study in Rene Dubos Hospital in France. Our population included neonates with definite NEC corresponding to Modified Bell’s stages II, III, and IV associated with clostridium butyricum and neonatale, diagnosed between January 2017 and November 2022.
Results: Among the 7 neonates diagnosed with clostridium infection associated with NEC, 85% of our populations were exclusively fed with human milk. Slower and intermediate rates of progression of enteral feeding strategies were associated with a higher risk of NEC. Bacteriological diagnoses were announced positive by blood culture after 18 +/- 6 hours with unidentified anaerobic germ. Microbiota analysis showed that 71% of our populations were clostridium neonatale and 29% were clostridium butyricum. Surgical intervention was necessary for all patients. An outbreak of necrotizing enterocolitis occurred within a 1-month period, in 3 neonates of our population. Blood culture from these neonates grew the same strain, clostridium neonatal.
Conclusions: A slow rate of progression of enteral feeding is associated with an increased risk of developing NEC. Medical teams should provide aggressive therapeutic management, incorporate anaerobic BC into diagnostic workups, and consider the use of PCR test for early detection of clostridial infections. Outbreak of necrotizing enterocolitis associated with clostridium neonatal is common, appropriate broad-spectrum disinfectant with hand hygiene and quarantine rules should be applied.

The article provides data on how, in the saline soils of the Bukhara region of the Republic of Uzbekistan, it is possible to carry out 3-4 summer cyclic rejuvenating pruning on overgrown branches, fruiting branches, grafted grafts and combinations of perennial different varieties of apple trees, tree formation, and the influence of methods and degrees of cyclic pruning on the illumination of the crown, leaf surface, dry weight and photosynthesis productivity of the apple tree. Four-year studies have shown that with 3-4-year cyclic rejuvenating pruning on overgrown branches, fruit-bearing branches, the total leaf area of the studied varieties decreased by 16-23%, but the size of each leaf plate increased by 21-32%. The highest net productivity of photosynthesis was noted in the leaves located in the upper part of the tree trunk, and the lowest - in the leaves located in the central part of the tree trunk, and increased to 0.10-1.25 g compared to the control. The average yield of fruit-bearing branches in 3 varieties of apple trees during the rejuvenation of branches according to a 3-4-year cycle is 4-16 eyes, an additional yield is obtained, respectively: 0.1-4.0 c/ha 0.9-3.5 c/ha; 0.6-3.1 q/ha.
The Increased Risk of Cryptogenic Stroke Associated with Patent Foramen Ovale in Young Adults
Authors: Knupp Alec , A. Smith Douglas
Published: November 2024

Ischemic stroke is defined as a reduction in blood flow to brain tissue that results in the deterioration and death of neurons in a matter of minutes. While often seen in older patients with a history of atherosclerosis of the major arteries, a subset of ischemic strokes occurs in younger individuals with minimal to no prior risk factors. Further evaluation of these unknown, or cryptogenic, strokes has yielded positive findings of a patent foramen ovale (PFO) in a concerning number of cases. Cryptogenic strokes attributable to PFO present an important clinical occurrence because they do not fit the typical template regarding those most at risk for such acutely devastating outcomes, making their identification uniquely important for both immediate and long-term patient care. A 20-year-old Hispanic female presented to the emergency department for evaluation of neurological symptoms indicating obstruction of a major cerebral vessel. After being placed on stroke alert and found to have an embolus occluding the left middle cerebral artery (MCA) via non-contrast computed tomography (CT), tissue plasminogen activator (tPA) was administered, and mechanical thrombectomy was performed to restore blood flow. Following stabilization, further testing done on the patient revealed a substantial PFO that likely allowed for the crossing of an embolus from venous blood returning to the heart directly into the arterial circulation. The patient opted for cardiac monitor placement and has remained asymptomatic to this point while awaiting surgical repair. This case demonstrates an unusual presentation of ischemic stroke in a young individual with no reported risk factors and highlights the importance of screening for large PFO in patients prior to a serious cerebrovascular accident. It is our hope that highlighting this case may heighten awareness of this condition and allow for timely recognition from medical personnel who may encounter this same medical emergency in the future.
Machine Learning and Deep Learning Based Healthcare System: A Review
Authors: Kumar Ashish , Kaur Jagdeep
Published: November 2024

The way medical data is evaluated, diagnoses are made, and patient care is provided has all changed dramatically as a result of the integration of machine learning (ML) and deep learning (DL) techniques in healthcare systems. An overview of the developments and uses of ML and DL in healthcare is provided in this study, with a focus on how they might enhance productivity, accuracy, and individualized care. The healthcare sector produces enormous volumes of data, which include patient-generated data, genetic information, electronic health records (EHRs), and medical photographs.ML algorithms have proven to be adept at managing this heterogeneous set of data by revealing patterns that were previously unknown, forecasting results, and offering insightful analysis. Furthermore, DL, a subset of ML, has demonstrated remarkable performance in voice and picture recognition tasks, which makes it a perfect fit for applications like natural language processing in healthcare and medical image analysis. Large dataset training algorithms can help medical practitioners detect illnesses early on, frequently before symptoms appear. Both patient outcomes and healthcare expenses can be greatly improved by this early identification. Furthermore, ML models can forecast the course of a disease and suggest individualized treatment strategies based on the unique characteristics of each patient. Medical imaging is a further field in which DL has shown impressive results. Tasks including tumor diagnosis, organ segmentation, and disease identification have been surpassed by Convolutional Neural Networks (CNNs) and other DL architectures over standard image analysis techniques. The use of deep learning (DL) in diagnostic imaging systems has resulted in improved precision and expedited interpretation of medical images, hence expediting diagnosis and treatment determinations. This paper proposes a comprehensive methodological framework to analyze and examine the heterogeneous data and better understand the relationship between depression and quality of life components using machine learning and deep learning techniques. To further validate the posterior probability multi-class Support Vector Machine's performance, the classification issues were extracted from the clustered data, and the self-organizing map produced a 08-cluster solution. Classification accuracy was 91.16% when the suggested model was used, which improved classification performance.

Dios nos llama a la oración y también a la misión, de modo que ambas llamadas están unidas hasta el punto de ser una única llamada. Los siete apartados del artículo muestran los aspectos esenciales de esta convergencia en la que oración y misión se reclaman mutuamente. La oración hace fecunda la misión y purifica el corazón del misionero. La misión nace de la experiencia del amor de Dios en la oración con el deseo de hacer amar a Dios. La dimensión comunitaria y fraterna se encuentra en el cruce entre oración y misión como una exigencia de ambas.
El Padrenuestro, orar en el corazón de la Trinidad
Authors: Carvajal Blanco Juan Carlos
Published: November 2024

El Padrenuestro es la oración que el Señor Jesús entregó a sus discípulos cuando estos le pidieron que les enseñara a orar. Desde ese instante, la Oración dominical es una de las “piezas maestras” de la catequesis y es iniciándose en ella como los cristianos de todos los tiempos, más allá de aprender una fórmula, participan de la misma oración del Hijo de Dios. De la mano del Ritual de la Iniciación Cristiana de Adultos, el artículo introduce en el dinamismo teologal que va implícito en la Oración del Señor. Este dinamismo se profundiza contemplando el testimonio que el Nuevo Testamento ofrecen de la oración de Jesús y su activación en sus discípulos por el Espíritu Santo. El estudio concluye ofreciendo algunas pistas para iniciar en el Padrenuestro, es decir, en la oración cristiana.

Published: November 2024

Gender policies in sports aim to promote the presence of women in management positions in sports organizations. In this context, from the data of three wide surveys conducted in Chile during the last decade, this article had two objectives: to compare the presence of women and men in boards of directions in different types of sports organizations; and to analyze differences in profiles between women and men in high-responsibility positions in each organization. The results showed a significant under-representation of women in management and leadership positions. The study found that Chilean sports organizations are vertically segregated, with a few having a balance between women and men, so despite the incorporation of women on boards of directors, there is still male predominance. The research highlights the need for measures for an effective application of gender policies in sports.

Las políticas de género en el deporte pretenden impulsar la presencia de mujeres en cargos directivos de organizaciones deportivas. En este contexto, a partir de los datos de tres amplias encuestas realizadas en Chile durante la última década, este artículo tenía dos objetivos: comparar la presencia de mujeres y hombres en los cargos directivos de diferentes tipos de organizaciones deportivas; y analizar las diferencias en el perfil de mujeres y hombres en los puestos de máxima responsabilidad en cada organización. Los resultados mostraron una significativa infrarrepresentación femenina en los cargos directivos y de liderazgo. El estudio constató que las organizaciones deportivas chilenas poseen una segregación vertical, siendo pocas las que cuentan con un equilibrio entre mujeres y hombres, de modo que a pesar de que se hayan incorporado mujeres en las juntas directivas, existe una predominancia masculina. La investigación releva la necesidad de medidas para la aplicación efectiva de políticas de género en el deporte.

Authors: Li Lizhi , Liang Jiang
Published: November 2024

This study investigated the supportive attitudes of residents in Changsha-Zhuzhou-Xiangtan toward the interactive development of sports events and urban tourism. The study employed a survey-based quantitative method, with a total of 115 residents participating. The survey assessed the impact through three key dimensions: economic impact, tourism image impact, and spatial impact, comprising 12 factors. The results indicated strong support among residents for the idea that sports events can generate economic benefits, enhance the urban tourism image, and stimulate spatial development. Sports events impact the tourism economy, improve the city's image, and create a cultural ambiance, fostering mutual growth between sports and tourism in the region. Pearson correlation analysis revealed a significant positive relationship (p<0.05) between sports events and tourism-related income, including transportation, dining, and accommodation. Residents' cognitive attitudes are explained by 35.5% of these factors, while 83.8% of their willingness to support the events is attributed to the same factors. Local governments should support distinctive sports events, optimize tourism resources, and enhance infrastructure to stimulate rapid economic growth.

Authors: Wang Danyi , Bo Xuesong
Published: November 2024

Constructing a competence model for volleyball coaches tailored to school characteristics has recently gained importance. This study aimed to clarify the competency model construction and its application effect. The study developed a volleyball coach competence model centered on knowledge, skills, professional roles, attitudes, and motivation. A quantitative methodology was used to assess the relationships between these dimensions and coaching performance, emphasizing teaching quality and overall effectiveness. The model drew from theoretical frameworks, including the Iceberg Model and the Onion Model. The sample consisted of 120 volleyball coaches. The correlation analysis revealed significant relationships among knowledge competence, skill competence, professional role, work attitude, work motivation, educational process factors, and educational target factors (pY1 < 0.05, pY2 < 0.05, and r > 0.1). The regression results indicated that gender, professional title, knowledge competence, professional competence, professional role, and work attitude positively influenced the achievement of the competency application effect (p < 0.05 and β > 0). In contrast, work motivation, age, teaching experience, education level, and salary showed no statistically significant impact (p > 0.05). Volleyball coaches' competence is essential for effective teaching and training, directly enhancing athletes' skills and performance. The model also improves coaches' quality and application ability, leading to increased athlete satisfaction and better training outcomes.

The aim of this study was to examine whether a relationship exists between the motivational climate and adolescents' interest, effort, and progression in learning in Physical Education classes, considering both gender and physical activity level. The following questionnaires were applied: PMCSQ-2, IEPA, AYES, and PAQ-C to a sample of n=3169 Chilean adolescents. The results were studied through descriptive and correlational analyses showing that there are statistically significant correlations when students perceive that the teacher acts intentionally in their classes towards the task climate, they show greater interest, effort and progression in their learning, highlighting greater motivation in the group that has mild PA in both males and females. But when these variables are related to ego climate, they only correlate positively in men, and negatively in women. When the dispositional and contextual variables are correlated, there is greater interest, effort and progress in learning in the PE class in men. It is necessary for PE teachers to focus their classes on the homework climate, because this will promote greater interest, effort and progression in learning, and will encourage possible adherence to the acquisition of healthier lifestyles.

El objetivo de este estudio fue examinar si existe una relación entre el clima motivacional y el interés, esfuerzo y progreso en el aprendizaje de los adolescentes en las clases de Educación Física, considerando tanto el género como el nivel de actividad física. Aplicándose los cuestionarios: PMCSQ-2, IEPA, AYES, y PAQ-C a una muestra de n=3169 adolescentes chilenos. Los resultados se estudiaron mediante análisis descriptivos y correlacionales mostrando que existen correlaciones estadísticamente significativas cuando los estudiantes perciben que el profesor actúa intencionadamente en sus clases hacia el clima tarea presentan mayor interés, esfuerzo y progresión en su aprendizaje, destacando mayor motivación en el grupo que tiene AF leve tanto en hombres y mujeres. Pero cuando estas variables se relacionan con el clima ego, solo correlacionan positivamente en los hombres, contrariamente a las mujeres estas son negativas. Cuando se correlacionan las variables disposicionales y las contextuales en los hombres existe un mayor interés, esfuerzo y progresión por aprender en la clase de EF. Es necesario que el profesorado de EF centre sus clases en el clima tarea, porque así potenciará un mayor interés, esfuerzo y progresión en el aprendizaje, y fomentará una posible adherencia a la adquisición de estilos de vida más saludables.

Maximum oxygen consumption VO2max has represented a fundamental reference when measuring cardiorespiratory fitness in different sports. The aim of this study was to present the results of ergometry tests with gas analysis in athletes who exceeded 70 ml/kg/min in VO2max, analyzing the correlations between VO2max and metabolic, cardiovascular, and respiratory parameters. The study was of a descriptive correlational type, and 27 male athletes participated. The r Pearson test was applied to determine the correlation between the variables. In the result analysis, correlations were determined: small between Age and VO2max (r = -0.238; p = 0.24); large between VO2max vs VO2VT1 (r = 0.741; p<0.001); VO2max vs VO2VT2 (r = 0.808; p<0.001); and VO2VT1 vs VO2VT2 (r = 0.783; p<0.001). Mean between VO2max and HR (r = 0.340; p = 0.09); large between absolute VO2max and VO2/HRmax (r = 0.840; p<0.001); small between VO2max and VE (r = 0.214; p = 0.30); small between VO2max and BR (-0.184; p = 0.37); small between VE and RR% (r = -0.281; p = 0.164). There were large correlations between VO2max and ventilatory thresholds, and there was also a large correlation between absolute VO2max and oxygen pulse, with small and non-existent correlations between VO2max and ventilatory parameters.

El consumo máximo de oxígeno (VO2max) ha representado una referencia fundamental a la hora de medir el fitness cardiorrespiratorio en deportes. El objetivo de este trabajo fue presentar resultados de pruebas de ergometría con análisis de gases en deportistas que superaron los 70 ml/kg/min en VO2max, se analizaron las correlaciones entre el VO2max y parámetros metabólicos, cardiovasculares y respiratorios. El estudio fue descriptivo correlacional, y participaron 27 deportistas masculinos. Se aplicó la prueba de r Pearson para determinar la correlación entre las variables. En el análisis de resultado se determinaron correlaciones: pequeña entre Edad y VO2max (r = -0,238; p = 0,24); grande entre VO2max vs VO2 VT1 (r = 0,741; p < 0,001); VO2max vs VO2 VT2 (r = 0,808; p < 0,001); y VO2 VT1 vs VO2 VT2 (r = 0,783; p < 0,001). Media entre VO2max y FC (r = 0,340; p = 0,09); grande entre VO2max absoluto y VO2/FCmax (r = 0,840; p < 0,001); pequeña entre VO2max y VE (r = 0,214; p = 0,30); pequeña entre VO2max y FR (r = -0,184; p = 0,37); pequeña entre VE y RR% (r = -0,281; p = 0,164). Se presentaron correlaciones grandes entre el VO2max y umbrales ventilatorios, también existió correlación grande entre el VO2max absoluto y el pulso de oxígeno, con correlaciones pequeñas e inexistentes entre el VO2max y los parámetros ventilatorios.

This study aimed to determine the influence of the outdoor education learning models and mental toughness on cardiorespiratory fitness (CRF) levels. A quasi-experimental method was used, employing a 2x2 factorial design. The 2x2 factorial design in this study involved two learning models: the TGT (Team Games Tournament) and STAD (Student Teams Achievement Division), along with two levels of mental toughness: high and low. The sample consisted of 80 students from Jakarta State University, enrolled in recreational sports courses. The subjects in this study were given the TGT and STAD learning models over a period of 9 weeks. The tests administered during the pretest measured cardiorespiratory fitness using the Bleep Test and mental toughness using a questionnaire. The results showed that both the TGT and STAD outdoor education models have a statistically significant impact on students' CRF levels (p<0.05). Additionally, an interaction effect was observed between the learning model and the level of mental toughness (p<0.05). Specifically, the TGT model showed a greater influence on CRF in students with high mental toughness (p<0.05), while the STAD model was more effective in students with low mental toughness (p<0.05). Both the outdoor education learning model and mental toughness influence the level of CRF, suggesting that outdoor education can enhance CRF, which may positively affect academic performance and mental health of students.

The aim of this study was to assess the general health status, daily life-healthy dietary patterns, and sports activity level of pregnant women, and to explore their relationship with the body mass index (BMI) of these women. This cross-sectional study employed descriptive and analytical methods. A total of 198 pregnant women from healthcare centers in Qasabat Al-Tafila participated. A questionnaire was developed consisting of two sections: demographic information, and a second section that included 38 questions distributed across three sub-domains: (1) General Health Status, (2) Daily Life-Healthy Dietary Patterns, and (3) Sports Activity. Statistical analyses were performed using SPSS (V20). The women’s general health status was rated as high (M=0.69), while both daily life-healthy dietary patterns (M=0.468) and sports activity (M=0.573) were rated as medium. The analysis showed statistically significant positive correlations between general health status, daily life-healthy dietary patterns, and sports activity with BMI (p < 0.01). Further, the results of multiple linear regression analysis indicated that these factors significantly influence BMI (p < 0.05). These findings highlight the important role of general health, daily life-healthy dietary patterns, and physical activity in shaping the BMI of pregnant women in Tafila Governorate. The study emphasizes the importance of promoting and maintaining a balanced and active lifestyle for pregnant women to optimize their health and well-being.
Contribution of reciprocal electrical stimulation across elbow muscles to motor recovery of infants with Erb's Palsy: A randomized controlled trial
Authors: Emam Elnegamy Tamer
Published: November 2024

This study examined the effect of reciprocal electrical stimulation (RES) across elbow flexors and extensors on the reaction of degeneration percentage and motor function in Erb's palsy infants. Forty infants with Erb’s palsy aged between 2-5 months were randomly allocated to one of two equal groups: the control group (A) received standard physical therapy, the study group (B) received traditional physical therapy plus a 15-minute RES through elbow flexors and extensors. For three months, interventions were carried out three times each week. The percentage of reaction of degeneration and motor function were assessed pre- and post-treatment using electromyography and Toronto active motion scale respectively. There was a significantly greater reduction in the percentage of reaction of degeneration and increase in the Toronto active motion scale score in the study group (B) as compared to the control group (A) (p < 0.001, p =0.007 consequently), indicating more improvements following the RES application. Incorporating the RES in the traditional rehabilitation programs for Erb's palsied infants is likely effective in improving motor functions. It is advisable for the pediatric physical therapist to consider such a therapeutic approach in caring for those infants.
Peran Pajak sebagai Instrumen Penyokong Pendidikan Inklusif untuk Meningkatkan Human Development Index (HDI) Indonesia: Sebuah Studi Literatur
Authors: Ilham Febri Budiman
Published: November 2024

Taxes are the largest source of revenue in the structure of Indonesia's state budget (APBN). The revenue will be allocated for state spending, one of which is on education. The education sector is a mandatory spending area amounting to 20% of the total state revenue. This paper aims to identify the role of taxes in supporting inclusive education to improve Indonesia's Human Development Index (HDI). The approach used in this research is qualitative with a literature study method using secondary data sources. The research results show that the increase and decrease in tax revenue affect the size of the education budget due to the dominant contribution of taxes to state revenue. HDI is influenced by indicators such as life expectancy, literacy rate, average years of schooling, and real per capita expenditure, all of which can be improved through inclusive education. Therefore, it can be concluded that if tax revenue increases, the education budget will also increase, and it will be able to fund inclusive education. Inclusive education will drive the increase in Indonesia's HDI. Some of the educational issues that occur include education that is not yet fully inclusive, the low quality of teachers, and the uneven distribution of school facilities and infrastructure. These problems can be resolved if there is significant educational funding, which is also influenced by tax revenue.
