Authors: Satim Caroline Cardoso Prado , Vidotti Daniela Barbieri
Published: September 2024

Este relato tem por objetivo descrever e apresentar reflexões acerca do desenvolvimento de uma oficina realizada no contexto do Estágio Supervisionado, no Colégio Estadual Cívico Militar Silvio Vidal – E.F.M., no 3° ano do Ensino Médio. O objetivo da oficina foi resolver problemas do cotidiano envolvendo o cálculo de medida de área e volume de um cone. A abordagem escolhida foi a Modelagem Matemática, uma estratégia de ensino e aprendizagem que visa resolver uma situação-problema do mundo real, por meio de um modelo matemático (BASSANEZI, 2013). Inicialmente realizamos uma atividade com o uso de um material manipulável, na qual foram fornecidos cones e cilindros feitos de cartolina, com mesma base e altura, e um pouco de areia, que os estudantes utilizaram para estabelecer uma relação entre o volume do cone e do cilindro, a fim de descobrir uma fórmula para calcular o volume do cone. Em seguida foi proposta uma atividade de Modelagem Matemática cuja situação-problema foi “Quanto sorvete cabe na casquinha?” (FREITAS; ANDRADE, 2014), na qual foram distribuídas algumas casquinhas de sorvete aos alunos com o intuito de que eles as utilizassem junto a fórmula encontrada na atividade inicial, para determinar o modelo matemático dessa situação. Por fim, os alunos também participaram de uma atividade em que tinham que determinar a marca de tinta com melhor custo-benefício para um projeto de pintura da Catedral de Maringá, na qual fornecemos duas opções de tintas, com os respectivos rendimentos e valores. Com isso pretendíamos explorar o conceito de área da superfície do cone. Como resultados, foi possível perceber que as estratégias utilizadas pelos alunos no desenvolvimento das atividades proporcionaram noções sobre os conceitos de área e volume de um cone, ajudando-os a entender como aplicá-los em situações do cotidiano, conforme priorizam as orientações curriculares.

Published: September 2024

This study aimed to identify the requirements for the application of artificial intelligence (AI) in diagnosing autism spectrum disorder (ASD) and the challenges facing its application, as perceived by specialists. The sample consisted of 423 specialists, with a mean age of 39.54 years and a standard deviation of 5.24, in the field of special education who work in the government and private sectors in the Kingdom of Saudi Arabia. The descriptive survey method was used. A questionnaire (set by the authors) was employed as a research tool. It consisted of 2 parts: The first gathered general information about the sample, while the second covered 4 dimensions distributed over 35 items. Statistical methods such as the mean, standard deviation, t-test, and one-way analysis of variance were applied using IBM SPSS Statistics (version 26). The results showed that the most important requirements for the application of AI in the diagnosis of ASD, as perceived by specialists, are the organizational, human, and financial requirements. It was also observed that the most common barrier to the use of AI in the diagnosis of ASD is the lack of awareness of the importance of applications of AI in the diagnosis of ASD. In light of these results, the research presents recommendations that would help specialists and agencies related to the diagnosis of ASD to facilitate the application of AI in the diagnostic process.

Published: September 2024

Stroke is considered one of the most common causes of disability around the world, with an estimated 13.7 million new stroke cases per year. The Postural Assessment Scale for Stroke (PASS) is a 12-item outcome measure that assesses balance while the patient maintains position and then changes position. This study aimed to translate the PASS from its original English version into Arabic [Arabic version of PASS (PASS-Arabic)]. This cross-sectional study was conducted between February 2022 and January 2023 in Saudi Arabia. The translated PASS was reviewed by 40 Arabic-speaking physical therapists to verify the comprehensibility of the tool. The translation process was conducted in accordance with Beaton’s instructions. Feedback from the physical therapists indicated that the PASS-Arabic was clear to read and understand. However, 5% of the physical therapists found that at least one item on the PASS-Arabic may be confusing for patients with regard to how to perform the task. Another three physical therapists thought that some tasks might be affected by a participant’s strength rather than their ability to maintain their balance. The translated and culturally adapted Arabic version of the PASS was found to be generally clear and comprehensible by Arabic-speaking physical therapists. The successful translation and cultural adaptation of PASS-Arabic enables a comprehensive balance assessment for Arabic-speaking stroke patients, empowers healthcare professionals, and improves stroke rehabilitation quality.

Published: September 2024

The propagation process of sweet corn (Zea mays L. saccharata group) is carried out through seeding. For good quality in this process, the operating speed and graphite dosage must be assertive for a greater plant stand and seed distribution and depth. Given the above, this research aimed to analyze three different operating speeds and the influence of graphite dose to evaluate the effects on plantability in sweet corn. A John Deere 4 x 2 TDA tractor with a nominal power of 78 kW (106 hp) and a Netz model PDN 6000 seeder were used to carry out the sowing. The area was part of an 18-hectare central pivot. Three operating speeds (5.0, 7.7, and 10.7 km h-1) and three amounts of graphite (4.0, 8.0, and 12.0 g for each kg of seed) used in mechanical seeders were evaluated. The experiment was carried out in a 3 x 3 factorial design in subdivided plots with 12 replications. The results were subjected to analysis of variance (ANOVA) using the “F” test, and subsequently, the means of the variables in the different treatments were analyzed using the Tukey test. Statistical process control was also analyzed using control charts with upper and lower limits drawn based on the ideal sowing spacing. In conclusion, the greatest uniformity of sowing was achieved with a speed of 5.0 km h-1, and a graphite dose of 12.0 g kg-1 provided the greatest uniformity of sowing. Higher operating speeds and lower graphite doses resulted in a higher number of failed or double germinations. The lowest seed spacing VC was when there was a higher dosage of graphite and a lower operating speed.

This study aims to explore and enhance community participation in mutual cooperation (gotong royong) for village environmental cleanliness, with a focus on Dusun Baru 2 Village. Gotong royong is an important tradition in many Indonesian communities that plays a significant role in maintaining environmental cleanliness and health. However, community participation in this activity is often influenced by various factors that can affect the effectiveness and sustainability of cleanliness programs. This research uses a qualitative method with a case study approach to understand the dynamics of community participation in gotong royong activities in Dusun Baru 2. Data were collected through in-depth interviews, observations, and analysis of documents related to gotong royong activities. The study also involved focus group discussions to gain perspectives from various community groups. The results of the study indicate that the level of community participation in gotong royong has significantly increased due to several key factors: greater awareness of the importance of environmental cleanliness, support from community leaders, and the provision of adequate facilities. These factors have strengthened the motivation of the community to engage more actively in cleaning activities. Community participation in gotong royong for environmental cleanliness in Dusun Baru 2 Village can be improved through strategies involving education, social support, and facility improvements, ultimately contributing to a cleaner environment and better quality of life.

Authors: Abdi Abdihakim Artan , Ali Ismail Mohamed , Mohamed Abdikadir Ahmed , Farah Faiza Abdulkadir
Published: September 2024

Subglottic stenosis is a serious complication of prolonged intubation in pediatric patients and Over 90% of acquired cases are iatrogenically caused and result from endotracheal intubation. Subglottic stenosis is an unanticipated problem that needs to be diagnosed and treated immediately. The majority of pediatric subglottic stenosis occurrences are mild to moderate. This case highlights the challenges and outcomes associated with this condition. Here, we present a 3-year-old child presented with high fever and scrotal pain with swelling, diagnosed as scrotal cellulitis. Laboratory results showed anemia, leukocytosis, and metabolic acidosis, and the child's condition deteriorated due to respiratory distress, requiring intubation and PICU admission. Following a scrotal abscess drainage, the child was discharged but returned with severe respiratory distress, cyanosis, and subglottic stenosis, confirmed by laryngobronchoscopy and imaging. After failed extubation attempts and further complications, a tracheostomy and endoscopic subglottic dilation were performed. The child was successfully decannulated after eight days, with near-complete recovery except for a slight change in voice tone. The case highlights the challenges in managing complex respiratory complications in pediatric patients. This case underscores the importance of monitoring for subglottic stenosis in children who have undergone prolonged intubation and demonstrates the efficacy of endoscopic dilatation in managing this complication.
Being-in-touch
Authors: Spitzer David M. ,   Philosophy Documentation Center
Published: September 2024

Neither denying the senses nor reducing sensibility to the auditory or the visual, the Parmenidean poem unfolds a zone where diverse living bodies are involved in various ways of touching and contact that together describe τὸ ἐόν (typically translated: being) as a differentiated contiguity ever-exceeding itself through—by means of—touch. Thematic stress on contact animates the poem of Parmenides, texturing an opening scene with detailed images of contact and touch that position the narrator as well as the narrated speaker Thea, deepening the narrated embodiments of the poem’s diverse figures. This study articulates modes of touch and contact throughout the poem’s conventional three-part division, illustrating the extent to which touch-contact permeates the text and restoring touch and embodiment to the Parmenidean poem.

Authors: Matur Utku Canci , Tüysüz Cansu , Köse Ali
Published: September 2024

The advent of modern technology has led to a significant increase in the utilisation of rechargeable secondary batteries. Despite the sustainability of lithium-ion (Li-ion) batteries, the limited availability of lithium has driven research into alternative energy storage technologies. Sodium-ion (Na-ion) batteries, as a potential alternative to Li-ion batteries, have emerged as a highly promising contender. However, for these batteries to become industrially viable, certain properties such as energy and power density need to be enhanced. To address this issue, batteries have been a focus of research, and battery thermal management systems have been developed. These systems aim to evaluate battery performance, which is strongly influenced by temperature. Effective thermal management ensures that the battery operates within the optimal temperature range. This study models a pouch-type battery and evaluates the effects of phase changing materials (PCM) on battery temperature control. Comparative analysis is conducted using different PCMs to understand their impact. The study analyses the battery's response to specific temperature ranges and assesses how different PCMs affect battery cooling performance. The results provide critical insights for ensuring efficient battery operation. Furthermore, this research supports the broader adoption of Na-ion batteries in industrial applications and contributes to the development of sustainable energy storage systems.
Exploring the future hydropower production of a run-of-river type plant in the source region of the Tigris Basin (Türkiye) under CMIP6 scenarios
Authors: Yalçın Emrah
Published: September 2024

This assessment presents a framework for exploring the changing climate impacts on the energy production capacity of a run-of-river type plant, using the Basoren Weir and Hydropower Plant (HPP) as a case study. The Basoren Project is planned considering historical streamflow records in the source region of the Euphrates-Tigris River Basin (ETRB), which is a prominent hotspot warming at nearly double the global average rate. The quantification is built on precipitation and maximum/minimum temperature datasets from 24 Global Climate Models (GCMs) belonging to the sixth phase of the Coupled Model Intercomparison Project (CMIP6) under the moderate- and high-end Shared Socioeconomic Pathway (SSP) scenarios of SSP2-4.5 and SSP5-8.5, as well as the CMIP6 historical experiment (HEXP) scenario. The distribution mapping method is employed to adjust the raw GCM datasets for systematic biases. The Soil and Water Assessment Tool (SWAT) is preferred in producing daily runoff time series for the bias-adjusted simulations of each GCM over the historical (1988-2009) and three future (2025-2049, 2050-2074, and 2075-2099) periods. The ramifications of the changing climate on the Basoren HPP's energy production capacity are assessed based on the medians of the operational results reached for each GCM under the future societal development scenarios of SSP2-4.5 and SSP5-8.5, considering the medians achieved under the HEXP scenario as the reference case. The results indicate potential reductions in the mean yearly energy production of the Basoren HPP by 7.9%, 5.5%, and 5.3% under the SSP2-4.5 scenario, and by 5.8%, 8.0%, and 17.3% under the SSP5-8.5 scenario for the periods 2025-2049, 2050-2074, and 2075-2099, respectively. While declining spillway releases are expected to partly offset the impact of decreasing streamflow rates on energy production, the shift from a snow-dominated to a rain-dominated hydrologic regime necessitates re-optimizing the power capacities of the ETRB plants to maintain effective use of hydropower potential.

Morals are very important for every person, especially for every Muslim. The formation of morals through moral education needs to be given to every child by parents since childhood. Childhood is the most important period in educating children, so there are not a few children who are educated and not educated properly by their parents. This research explains the urgency of current behavior or morals that have deviated from existing teachings. Therefore, this research aims to find how to rebuild children's moral education, both from educational patterns from parents and educational institutions. This research uses a qualitative approach method, with data derived from secondary data. Data collection techniques were carried out with documentation studies. Then, descriptive data analysis was carried out and finally conclusions were drawn. the importance of moral education for children, starting from the role of parents from an early age. Although schools and madrasahs have an important role in shaping character, collaboration with the family environment is often less than optimal. Parents are expected to remain the main pillar in shaping children's morals, although not all children get adequate moral education from their parents. Active collaboration between parents and teachers, especially in madrasah, is needed to instils the values of discipline and honesty in children. In the Islamic context, family education reinforces the importance of religious teachings in daily life. Suggestions to strengthen the role of madrasah as a formal institution that integrates Islamic religious education as a whole, increase collaboration with parents through open communication, and organize training for parents, are expected to increase the effectiveness of children's moral education holistically.

Published: September 2024

The main purpose of this study is to assess the level of stakeholders’ compliance to the waste management of electrical and electronic guidelines in Bauchi Metropolis and its environs. It comprised of identifying the procedures for handling e-waste and the level of compliance of various stakeholders to the existing e-waste guidelines in Nigeria. Systematic sampling technique was employed to identify the respondents in the study area. The data for this study were collected through site visit and field study questionnaires. A total of 200 valid responses were collected from the survey questionnaire. The responses generated from the survey questionnaire was analysed using excel software to compute descriptive statistics method. The findings of this study demonstrated that level of compliance was close to be the best among the manufacturers, whereas, 80% meet the requirement of standard organization of Nigeria (SON). In addition, 90% of importers do not dispose of e-waste in an environmentally sound manner. Similarly, 93.61% of household neither knew what are e-waste and its hazardous nature. Results revealed that compliance was moderate among the importers, re-users and disposal, except for retailers,
recyclers, dismantlers which shows low compliance to waste electrical electronic guidelines limits. It is likely that the demand for electrical and electronic equipment’s and ultimately, the quantity of e-wastes generated will continue to increase as the city continues to grow, which means National Environment Standard and Enforcement Agency (NESREA) should thus recognize e-waste management as a priority and work to prevent further environmental degradation by adopting effective policy.

Published: September 2024

Cotton being the high value, non-food, fiber crop is grown across seventy countries supporting the lives of closely one billion people. Considering the global importance of crop the study was taken up to assess the growth performance of crop at different levels. Compounded annual growth rates, instability rates and source of instability were estimated for area, production and productivity of ‘white gold’. Inter country, inter states and the inter districts comparison was done for the world, India and the Telangana state, respectively. At global level there was negative growth in the area but there was inclining production and productivity. Mean yield change was the major source of growth in average production at world level. India saw quantum leap in area and production after Bt cotton introduction. The instabilities among the states declined with the spread of new technology. Interaction between changes in the area variance and the mean yield was the source of growth for India. Telangana one of among major cotton producing states also went about rapid acreage expansion with the adoption of Bt cotton. Inclining mean area brought in uprising average production of the crop in the state. Recent decade has seen stagnating and lower productivities in both the state and country. Hence, there is need for new traits to offer resistance against rising pests and new innovative technologies to be developed.
Atlas Básico de Histología Veterinaria
Authors: Gómez Sánchez Miguel Ángel , Párraga Ros Ester , Bernabé Salazar Antonio
Published: September 2024

El Atlas Básico de Histología Veterinaria nació como un recurso didáctico sencillo para ayudar a recordar a los estudiantes de veterinaria de Anatomía Patológica Especial, asignatura que en el plan actual de estudios de la Facultad de Veterinaria de la Universidad de Murcia se encuentra en tercer curso. Pero a instancia del profesor Bernabé-Salazar, el proyecto del atlas se hizo más amplio y de libre acceso. Se incorporó al proyecto una persona joven, la profesora Párraga-Ros, pensando en el futuro con la intención de perpetuar la introducción de nuevas imágenes al catálogo iconográfico del Atlas Básico de Histología Veterinaria. El Atlas Básico de Histología Veterinaria está dividido en 20 capítulos, que tratan las tres secciones de la Histología: citología, histología propiamente dicha y la histología especial u organografía microscópica. La citología se aloja en el capítulo uno, generalidades, y se desarrolla en 10 páginas. Este mismo capítulo hace un vistazo rápido a los cuatro tejidos básicos (una página) y a la conformación de los órganos (seis páginas) como preámbulo a las páginas siguientes. Seis capítulos versan sobre los tejidos: epiteliales (capítulo 2), conectivos (capítulo 3, 4 y 5), musculares (capítulo 6) y nervioso, que incluye el sistema nervioso (capítulo 7). La histología especial u organografía microscópica se muestra en 13 capítulos, empezando por el sistema cardio-circulatorio (capítulo 8), sistema hematopoyético y linfoide (capítulo 9), la piel y sus anejos (capítulo 10), sistema endocrino (capítulo 11), aparato respiratorio (capítulo 12), aparato digestivo (capítulos 13, 14, 15 y 16 – hígado y páncreas-), aparato urinario (capítulo 17), aparato genital de la hembra (capítulo 18), aparato genital del macho (capítulo 19) y el capítulo 20 dedicado al ojo y oído. Hemos querido utilizar las técnicas de rutina, de fijación -formol al 10%-, procesado en parafina y tinción -hematoxilina y eosinas y tricrómico de Masson-, para que las preparaciones fueran como cuando se hace diariamente en el laboratorio de Histología y Anatomía Patológica de la Facultad de Veterinaria de la Universidad de Murcia. Las imágenes se han obtenido en un foto-microscopio con cámara digital y, a veces, con la cámara de un teléfono móvil para obtener una fotografía panorámica. También, se han mejorado con un procesador de imágenes. Hemos utilizado el formato de página apaisada porque el ordenador tiene la pantalla rectangular y de esta forma, también damos protagonismo a la imagen, al detalle. El texto se ha hecho casi telegráfico, en muchas ocasiones no hay verbo, pero es totalmente comprensible.

Published: September 2024

Introducción: Esofagitis eosinofílica, enfermedad crónica inmunomediada, caracterizada por infiltración de eosinófílos del epitelio, síntomas de disfunción esofágica, requiere endoscopia con biopsias para diagnóstico definitivo. Reportes recientes hablan de aumento mundial. Objetivo: Caracterización de Esofagitis Eosinofílica en 2 centros pediátricos especializados, uno público (Hospital de Niños JM De Los Ríos) y otro privado en los últimos 20 años (2003-2023). Métodos: Estudio retrospectivo, descriptivo y longitudinal, revisión de base de datos, determinación de diferencias en frecuencia, edad, sexo, síntomas, hallazgos endoscópicos e histopatológicos. Se usó Programa OpenEpi, estadística descriptiva, prueba t-student y Chi-Cuadrado. Resultados: 27 pacientes con hallazgos endoscópicos sugestivos de Esofagitis Eosinofílica, 15/27 (4 centro público y 11 centro privado) presentaron diagnostico histopatológico. Predominó sexo masculino (73,3%), adolescentes 3/4 en centro público y pre-escolares 8/11 en centro privado (diferencia significativa p 0,028). Hallazgo endoscópico predominaron surcos y aspecto cuadriculado 8/11 centro privado y exudados blanquecinos seguidos de anillos 2/4 respectivamente, centro público. Predominó presentación con clínica de RGE y disfagia a sólidos, centro público y vómitos seguidos de disfagia a sólidos, centro privado. 86% de casos se diagnosticó entre 2010-2014. Conclusión: Esofagitis Eosinofílica es poco frecuente en niños, observamos mayor frecuencia de casos, en niños de menor edad en centro privado y adolescentes en centro público. Presentación con síntomas generales como vómitos en niños pequeños a diferencia de disfagia e impactación de alimentos, principales síntomas en adolescentes y adultos, puede retardar la sospecha y el diagnóstico en edades tempranas. No hubo aumento de casos en los últimos años.

Authors: Sivira Pedro , Echeverría Gabriel , Linares Beatriz
Published: September 2024

El cáncer de esófago constituye la sexta causa de muerte por cáncer en el mundo. El tipo histológico lo constituyen en un 95% de los casos el escamoso y el adenocarcinoma. Ambos tumores poseen un mal pronóstico, ya que suelen diagnosticarse en estadios avanzados en los que, a pesar de las opciones terapéuticas disponibles, sólo se logra una supervivencia de un 10-15% a los 5 años. El síntoma principal es la disfagia, que suele ser constante y progresiva, comenzando por disfagia a sólidos y progresando a líquidos. El tratamiento endoscópico paliativo merece una consideración aparte ya que está indicado cuando existe una gran afectación locorregional (T4) o metástasis a distancia, y sólo para paliar la disfagia, el dolor torácico, las complicaciones de una fístula traqueoesofágica o la desnutrición del paciente. En este sentido, la mejor aportación de la endoscopia se centra en la colocación de una prótesis metálica autoexpansible que asegure la permeabilidad del segmento estenótico. Describiremos la clínica, diagnóstico y tratamiento paliativo de un paciente femenino de 69 años con Carcinoma de células escamosas moderadamente diferenciado de esófago.

Introducción. Diferentes estudios han sugerido un efecto protector de la infección por Helicobacter pylori (Hp) contra enfermedad alérgica y otras condiciones autoinmunes. Objetivo: Investigar la presencia de enfermedad alérgica en niños con gastritis crónica con o sin infección por la bacteria. Pacientes y método: Estudio de cohorte, prospectivo, observacional y analítico, enero-julio 2023. Los pacientes agrupados según el reporte histológico de gastritis crónica con Hp (grupo A) y gastritis no Hp (grupo B). Se investigó sobre enfermedades alérgicas (asma, rinitis, dermatitis, urticaria, alergia alimentaria o aeroalérgenos). Se determinó razón de probabilidades (OR) y p de significancia estadística. Resultados: Un total de 59 pacientes. Grupo A: 41 pacientes, edad 7,81±3,23 (2-14años), 26 masculinos (63,41%), y el dolor abdominal fue prevalente 85,37%. Grupo B: 18 pacientes, edad 8±2,74 (2-13 años), 11 masculino (61,11%), y 50% refirió diarrea. La alergia respiratoria estuvo presente en 7(17,07%) niños con gastritis crónica Hp, 4 asma y 3 rinitis alérgica; y en 10(55,55%) con gastritis Hp negativo, 7 con rinitis y 3 asma. Se determinó OR= 0,1647 (CI 95%: 0,0478-0,5665) p=0,1530. Al investigar alergia alimentaria se encontró en 29,26% de los niños infectados con Hp y 50% de los Hp negativo, OR= 0,4137 (CI95%: 0,1319-1,2976) p=0,0397. Discusión: el Hp favorece la respuesta inmune TH1 sobre TH2, lo que disminuye el desarrollo de enfermedad alérgica, asociación en concordancia con los resultados obtenidos. Conclusión: los niños infectados con Hp tienen una probabilidad protectora mayor contra las enfermedades alérgicas respiratoria o alimentarias con respecto a los no infectados.
Assumption of the Default Debt by the Obligated Person
Authors: Gruzdev Vladislav
Published: September 2024

The institution of debt assumption is traditionally used in domestic civil law to regulate property turnover, which attracts the close attention of representatives of civil science. At the same time, the debt assumption is qualified in different ways: as a unilateral transaction, a legal act, transactionlike actions. Using formal-logical and historical research methods, the author proves that the assumption of the default debt is a unilateral transaction, for which it is necessary and sufficient to express the will of the obligated party. This transaction is made in favor of the opposite side of the legal relationship and entails legal consequences in the form of its change, namely, it modifies the violated subjective right in the direction of qualitative improvement: it prolongs the existence of powers capable of enforcement (in case of debt assumption during the limitation period) or returns such powers lost due to the expiration of the limitation period (in the case of debt assumption after the expiration of the statute of limitations). By assumption of the debt addressed to the authorized person, the person confirms the existence of his obligation to a certain extent, in connection with which it is logical to calculate the term for the enforcement of the violated right anew. The authorized person's awareness of the transaction in question is necessary, but not to establish the legal effect of the transaction, but in order to take advantage of its benefits. The types of assumption of the default debt and the form of this transaction, acceptable evidence of its commission are considered. It is concluded that in the absence of admissible evidence, the debt assumption transaction is unfulfilled. Based on the results of the study, proposals for amendments and additions to Articles 203, 205, 206 of the Civil Code of the Russian Federation were formulated.

Ekstrak Daun Pandan Wangi (Pandanus amaryllifolius Roxb) memiliki senyawa flavonoid yang berfungsi sebagai antiinflamasi yang dapat digunakan untuk mengobati luka bakar. Penggunaan ekstrak daun pandan wangi dinilai kurang praktis sehingga untuk mempermudah pengaplikasiannya diformulasikan dalam sediaan gel. Gelling agent dalam sediaan gel berperan penting pada karakteristik gel yang dihasilkan, gelling agent HPMC dapat menghasilkan gel yang jernih dan stabil dalam penyimpanan. Penelitian ini bertujuan untuk memperoleh formulasi sediaan gel yang memenuhi syarat evaluasi sediaan dan untuk mengetahui pengaruh konsentrasi HPMC terhadap evaluasi sediaan gel. Sediaan gel diformulasikan menjadi tiga formula dengan variasi konsentrasi HPMC yaitu F1 (1%), F2 (2%) dan F3 (3%). Pengujian sediaan dengan metode cycling test selama enam siklus pada suhu 4℃ dan 40℃, selanjutnya dilakukan uji organoleptik, uji homogenitas, uji pH, uji viskositas, uji daya lekat dan uji daya sebar. Data hasil evaluasi dianalisis secara statistik dengan uji One Way Anova.  Hasil penelitian menunjukan F1 memenuhi persyaratan uji orgenoleptik, homogenitas, pH, viskositas dan uji daya sebar tetapi tidak memenuhi uji daya lekat, F2 memenuhi persyaratan uji orgenoleptik, homogenitas, pH, dan uji daya lekat tetapi tidak memenuhi uji daya sebar dan uji viskositas, dan F3 memenuhi persyaratan uji orgenoleptik, homogenitas, pH, dan uji daya lekat tetapi tidak memenuhi persyaratan uji daya sebar dan uji viskositas. Variasi konsentrasi HPMC sebagai gelling agent memberikan pengaruh secara signifikan (p<0,05) terhadap uji pH, viskositas, daya lekat dan daya sebar, tetapi tidak berpengaruh secara signifikan (p>0,05) terhadap uji organoleptik dan homogenitas.

Catheter- related bacteremia (CRB) presents as a complication in patients with stage V chronic kidney disease, due to the use of temporary vascular catheters for this purpose, being associated with infections by microorganisms that colonize the skin, most frequently Staphylococcus aureus, either methicillinsensitive or resistant. This condition can be complicated by septic emboli in organs distant from the primary focus of infection, ranging from the lung, heart, to the eye, as exemplified by the case to be presented. Thus, CRB represents a serious condition, with a mortality rate of 18% at one month and 27% at 3 months, which must be managed early in order to eliminate the microorganism from the bloodstream as well as from other organs affected by it.
Android Application for Managing Urgent Convalescent Plasma Blood Request for Covid19 Treatment
Authors: Nasir Olid , Dewi Deshinta Arrova
Published: September 2024

The emergence of the covid19 pandemic has forced many countries to be more focused on the technologies that can save human life. A lot of efforts have focused on containment and mitigation actions with varying degrees of success. However, lack of attention given to administering urgent requests for convalescent plasma blood as part of treatment for critical covid19 patients although the passive administration of antibodies from a person who has convalesced may be an effective therapy for those patients who have yet to develop their antibody response. Hence, interest in the use of convalescent plasma has been rising, not only commenced by medical professionals but also among patients’ family members, especially for urgent requests. This paper proposed timeline-based posts to tackle the urgent-request issue that sort based on first come first serve priority. From this timeline, the people in search of donors may find donors’ information and location quickly. Furthermore, we added a timeline page, search function, a virtual assistant (chatbot) that automatically shares posts to social media without exiting the app, etc. These features promote the hit to the right users and their respond faster than before. The previous study reported from the 40 PSARS patients undergoing ribavirin and methylprednisolone treatment, 19 were administered with convalescent plasma, whereas 21 were given an additional dose of methylprednisolone. The group of patients who were treated with plasma therapy showed better recovery and reduced mortality. With this situation, we hope our contribution in the form of an Android app can assist those in need at the right time and save more lives. Moreover, this app can be referred to as a model for other comparable apps.
