Menjaga Sentuhan Manusia dalam Pendidikan pada Era Digital: Peran Personalisasi, Interaksi Sosial, dan Aktivitas Fisik
Authors: Orong Yohanes
Published: February 2025

Perkembangan teknologi digital telah membawa perubahan signifikan dalam dunia pendidikan, mulai dari penggunaan platform pembelajaran online, alat bantu digital, hingga integrasi kecerdasan buatan (AI). Transformasi ini menawarkan kemudahan akses informasi, fleksibilitas waktu belajar, dan personalisasi pembelajaran yang lebih baik. Namun, di sisi lain, ada kekhawatiran bahwa interaksi manusia yang mendalam dan langsung bisa terpinggirkan. Penelitian ini bertujuan untuk mengkaji peran sentuhan manusia dalam pendidikan berbasis teknologi dengan menyoroti aspek personalisasi, kompetensi sosial-emosional, dan aktivitas fisik yang tidak dapat digantikan oleh teknologi. Metode yang digunakan dalam studi ini adalah pendekatan literature review, yaitu Systematic Literature Review (SLR). Melalui pendekatan SLR ini dilakukan identifikasi, seleksi dan evaluasi, ekstraksi dan analisis data, sintesis dan penyajian hasil. Data penelitian bersumber dari berbagai dokumen tertulis seperti buku, jurnal ilmiah, ensiklopedia, dan internet. Hasil studi menunjukkan, pendekatan personal, sentuhan emosional, interaksi sosial, dan aktivitas fisik selama pembelajaran di sekolah tetap merupakan elemen penting yang tidak tergantikan. Penggunaan alat bantu digital dan kecerdasan buatan (AI) sama sekali tidak dapat menggantikan pentingnya elemen-elemen tersebut.  Studi menegaskan walaupun pemakaian teknologi, platform digital, artifisial inteligen, dan pendekatan hybrid tidak terelakkan dalam pendidikan, tetapi pendekatan personal, interaksi sosial-emosional, dan aktivitas fisik tetap menjadi elemen-elemen yang niscaya dalam pendidikan.

Authors: Affandi Syihabuddin , Maryanto Eddy , Kurniawan Yogiek Indra
Published: February 2025

Sepak bola bukan hanya sekadar olahraga, tetapi juga industri bernilai miliaran dolar, khususnya di Eropa. Salah satu aspek krusial dalam industri ini adalah penentuan nilai pasar pemain, yang menjadi dasar bagi transaksi transfer pemain. Nilai pasar pemain dipengaruhi oleh berbagai faktor, seperti performa, usia, posisi, serta aspek fisik dan mental. Namun, terdapat kesenjangan dalam penilaian nilai pasar, di mana pemain dengan statistik performa tinggi terkadang memiliki nilai pasar yang lebih rendah dibandingkan pemain dengan performa yang kurang optimal. Oleh karena itu, prediksi nilai pasar pemain secara objektif menjadi tantangan penting bagi klub sepak bola dalam pengambilan keputusan strategis. Penelitian ini mengusulkan model prediksi berbasis Random Forest untuk mengestimasi nilai pasar pemain secara objektif dengan memanfaatkan data atribut permainan dari Football Manager 2023. Dataset mencakup 1.405 pemain dari lima liga top Eropa (berdasarkan koefisien UEFA 2023) dengan 66 variabel. Metodologi penelitian meliputi tahap preprocessing data (handling missing values,label encoding), Exploratory Data Analysis (EDA), pembangunan model Random Forest, dan implementasi sistem berbasis web. Pembagian data menggunakan rasio 80:20 (training-testing), sementara evaluasi kinerja model dilakukan melalui metrik RMSE (Root Mean Squared Error), MAE (Mean Absolute Error), dan R² (Koefisien Determinasi). Hasil eksperimen menunjukkan bahwa model baseline dengan parameter default memperoleh nilai Root Mean Squared Error (RMSE) sebesar 0.63, Mean Absolute Error (MAE) sebesar 0.517, dan koefisien determinasi (R²) sebesar 0.75. Setelah dilakukan optimasi hyperparameter menggunakan Grid Search, kinerja model mengalami peningkatan yang signifikan dengan RMSE sebesar 0.62, MAE sebesar 0.513, dan R² sebesar 0.76. Model optimal diimplementasikan ke dalam sebuah situs web untuk mempermudah melakukan prediksi nilai pasar pemain. Hasil penelitian menunjukkan bahwa model Random Forest Regression mampu memberikan prediksi nilai pasar dengan tingkat akurasi yang lebih baik dibandingkan metode lain yang telah diuji dalam penelitian terdahulu.
On L1-biconservative Lorentzian hypersurfaces of Minkowski 5-space
Authors: Pashaie Firooz
Published: February 2025

A Lorentzian hypersurface x :M^4_1 ------>L^5 isometrically immersed into the Lorentz-Minkowski 5-space L^5, is said to be L_1-biconservative if the tangent component of vector field (L_1)^2 x is identically zero, where L1 is the linearized operator associated to the first variation of 2nd mean curvature vector field on M^4_1 . Since L_0 = D is the well known Laplace operator, The concept of L1-biconservative hypersurface is an extension of ordinary conservativity which is related to the physical concept of conservative stress-energy with respect to the bienergy functional. We discuss on Lorentzian hypersurfaces of L5 having at most two distinct principal curvatures. After illustrating some examples, we prove that every L_1-bicoservative Lorentzian hypersurface with constant ordinary mean curvature and at most two distinct principal curvatures in L^5 has to be of constant 2nd mean curvature.

The Impact of Brand Perception and Customer Satisfaction on Online Buying Behavior for Cosmetic Products: An Empirical Study of Female Consumers in Gujarat
Authors: Uma Badgujar, Kunjal Sinha
Published: February 2025

This study explores the online cosmetic purchasing behavior of female consumers in Gujarat, India, focusing on the relationships among brand perception, customer satisfaction, brand trust, and online purchasing behavior. Existing literature has explored these factors individually, but little research has been conducted on how customer satisfaction mediates the impact of brand perception on online buying behavior and how brand trust moderates the effect of customer satisfaction. This study, using a correlational design and quantitative approach, collected data from 390 female consumers across diverse demographic groups using a structured questionnaire. The conceptual model under study comprises five main constructs: brand perception, customer satisfaction, brand trust, online platform trust, and purchasing behavior on the Internet. Data were analyzed through the use of Structural Equation Modeling (SEM) in ascertaining the direct, indirect, and moderating effects between the variables. This would reveal that the two influences of brand perception and trust in online platforms significantly determine online purchasing behavior, where customer satisfaction mediates both aspects. In fact, this study showed that customer satisfaction also moderated the effect of brand trust on purchase behavior. This research study suggests that businesses need to focus on building great brand images, trust building online, and improving customer satisfaction to influence consumer behavior, increase purchase intentions, and drive sustained growth in the online cosmetic market.
BLEIFREI, BAUCHFREI, BÜGELFREI: ZU WORTBILDUNGEN AUF -FREI IM DEUTSCHEN UND IHREN ENTSPRECHUNGEN IM RUMÄNISCHEN
Authors: CRIVĂȚ Bogdana
Published: February 2025

The paper aims at investigating German adjectives ending in -frei with regard to their defining features and their actual language use. As it will be shown, the current expansion of such complex adjectives and the speakers’ noticeable preference for constantly coining new and ad-hoc lexemes exhibiting the structure [noun/verb + frei] are a consequence of their fairly complete lack of selective restrictions concerning the first element, their transparent meaning and the influence of similarly patterned English lexemes. The paper further discusses means of translating compounds with the semi-affix -frei into Romanian. The semantically often underdetermined synthetic German words are contrasted with Romanian derivative adjectives comprising negative prefixes, as well as with prepositional phrases or relative clauses which explicitly render the underlying relation.
KOMPONENTENZAHL IM NOMEN-NEUBILDUNGSKOMPOSITUM UND POLYSEMIE/MONOSEMIE-WERT SEINES DETERMINATUMS: SYNERGETISCH-QUANTITATIVER ANSATZ
Authors: DREBET Viktor , BUSCH Albert
Published: February 2025

The article is devoted to studying the generation of complex nouns-neologisms in modern German-language press in the correlation between the number of the compound-neologism components and the semantic volume of the dominant neological component, from linguistic-synergetic positions. The study assigns methodological importance to the position, postulating that the driving factor is the synergetic law of conservation of speech energy and minimization of efforts for the human mental lexicon. The indicators obtained based on quantitative investigation methods confirm that the mechanisms of language self-regulation are optimally directed towards the generation of complex nouns-neologisms in the non-multidimensional format of the studied correlation, which testifies to the benefit of the synergetic law of speech energy conservation and minimization of efforts for the human mental lexicon.
WHAT IS NOT IN THE TEXT: TOWARDS THE PROBLEM OF IMPLICITNESS IN DRAMA
Authors: ERLIKHMAN Anna , KULCHYTSKA Olga
Published: February 2025

This article examines implicitness, its realization and decoding by lexical-semantic means in fiction. The authors substantiate their claim that implicitness is an inherent language feature co-existing with explicitness. Establishing the perspective of a linguist-literary scholar, the authors provide a multi-level meaning presentation from literal to figurative and symbolic, based on discourse analysis. It is shown that much of the meaning can be concealed in the text and extend the limits of the latter. The analysis reveals that implicitness develops by lexical-semantic and lexical-syntactic means, through a diverse array of generative and interpretative devices.
FUNCTIONAL TRANSPOSITION OF ‘SINCE’ IN THE ENGLISH LANGUAGE
Authors: KOVBASKO Yurii
Published: February 2025

The paper is aimed at tracing the evolution of the preposition, adverb, and conjunction SINCE as the initial and transposed categories. The research proves that the adverb SINCE was formed due to grammaticalization of the construction SIÐ ÐAN/SIÞ ÞAN in 850-950 and has undergone functional transposition into the conjunction and the preposition. The adverb SINCE has been constantly decreasing and reached the lowest point in the early Present-day English. The functional transposition of the adverb SINCE into the conjunction in 850-950 was characterized by its immediate institutionalization and its statistics have been growing steadily with an upsurge in 1350-1420 and a constantly fluctuating growth after that. The transposed category of the preposition was formed in 1250-1350 and was institutionalized in the next stage of Middle English and since then, its usage frequency has been fluctuating from 18.2% to 24.1%, depending on the period.
CARPATISMELE VLAHE ÎN CULTURA CONTEMPORANĂ POLONEZĂ
Authors: OCZKO Anna
Published: February 2025

Although the spread of the literary language has contributed to the gradual disappearance of some old regional terms, others, such as culturemes, have become a symbol of the identity of mountain communities and were recognized as such in other parts of Poland, sometimes “borrowed” into sociolects foreign to mountain culture. Others have become a trademark. In this paper, I analyse the contemporary function of culturemes inherited from the Vlach shepherds and the contexts in which they are used today. According to ethno-linguistic studies, we understand culturemes as synonyms of key words endowed with various meanings thanks to which the specificity of an ethnic and regional community can be understood.

Authors: CÎNDEA Iulia Elena , CÎNDEA Cosmin
Published: February 2025

Language acquisition is a complex, multifaceted process crucial to understanding human cognition and informing language education. The present article presents a comprehensive review of the predominant theories and perspectives in language acquisition, integrating insights from interdisciplinary research. By analysing the contributions of key theories – behaviourism, nativism, sociocultural, or cognitive approaches – and evaluating their empirical support, we offer a nuanced understanding of how language development is shaped across diverse contexts. Highlighting the contributions of seminal theorists such as Skinner, Chomsky, Vygotsky, and Piaget, alongside contemporary research into bilingualism by Bialystok, Kuhl and others, this paper navigates through the complexities of language acquisition.
DIE DYNAMIK DES GEBRAUCHS VON AUSTRIAZISMEN IM GEGENWÄRTIGEN DEUTSCHEN MEDIENDISKURS
Authors: DROBAKHA-SIMONOVA Larysa , TARANUKHA Tetiana , IHNATOVA Olena
Published: February 2025

The article examines the dynamics of the use of Austrian terms in modern German mass media. The newspaper discourse was chosen for the analysis, since the spread of Austrian terms can be easily traced, in particular, in the German newspapers “Zeit”, “Berliner Zeitung” and “Tagesspiegel”. By sampling, Austrian terms were singled out whose values are focused on certain characteristics of a person. Along with the more popular analysed lexemes, which were found in all three editions, less common ones were also found, which appeared in two or one of the analysed newspapers. The results of the analysis show that the studied Austrian terms are very often used in German language, since newspaper discourse as a tool of mass communication always uses linguistic means that are relevant to society to some extent.
LA SYLLABE EN BIRIFOR REVISITÉE
Authors: TIROGO Issoufou François
Published: February 2025

This article deals with a re-analysis of the syllable in Birifor. After an initial interpretation of this phonological unit in a structural perspective, which led to the result that there are syllables with a coda in the language, the present study aims to be an answer to certain questions. In the context of government theory, the analysis reveals that it is the core that governs the onset. In CVC stems, the final -C# consonant is not a coda but the onset of a second empty-nucleus syllable. This is justified by the fact that sonants automatically legitimize empty nuclei in final position in Birifor. Also, in CVV structures, the VV sequences do not belong to the same syllable. -V- is the nucleus of the first syllable and -V# represents the nucleus of the following empty-attacking syllable.

The effect of Terebinth oil on Ezrin and Moesin expression levels in rats with ovarian ischemia-reperfusion Injury
Authors: Pektanç Şengül Gülsüm , Şengül Seydi Ahmet , Deverci Engin
Published: February 2025

The objective of this study is to examine the expression levels of ezrin and moesin proteins from a molecular and immunohistochemical standpoint following the administration of terebinth oil in rats with ovarian ischemia- reperfusion injury. A total of 32 female Sprague-Dawley rats were utilized in the study. The rats were randomly assigned to one of four groups, with eight rats in each group: control, ischemia, I/R, and I/R+-terebinth oil. Following the induction of torsion, the treatment group received 2 ml.kg-1 of terebinth oil orally via gavage once daily for 28 d. At the conclusion of the experiment, ovarian tissues were obtained for immunohistochemical and molecular analysis. The immunohistochemical evaluation demonstrated a positive ezrin expression in epithelial cells within the I/R+-terebinth oil group, in comparison to the I/R group.  Conversely, a negative reaction was observed in the vicinity of blood vessels. The expression of moesin was observed to be positive in granulosa cells and stromal areas. Additionally, a notable decline in the expression levels of ezrin and moesin proteins was observed in the treatment group in comparison to the damage group. Moreover, the administration of terebinth oil was observed to result in protein expression levels that were more closely aligned with those observed in the control group. The present study has demonstrated the impact of terebinth oil administration on the expression levels of ezrin and moesin proteins in a model of ovarian ischemia-reperfusion injury.
Dieta del zorro de páramo Lycalopex culpaeus (Molina, 1782) (Mammalia: Carnivora: Canidae) en la Reserva Ecológica Los Ilinizas, Ecuador
Authors: Cadena-Ortiz Héctor , Ordóñez-Pozo Carmen , Freire Efraín , Brito Jorge
Published: February 2025

El zorro de páramo Lycalopex culpaeus (Molina, 1782) es el cánido andino de mayor tamaño en Ecuador. Para esta especie, el conocimiento de los aspectos asociados a su dieta es muy escaso en el país, con muy pocos estudios para las poblaciones del norte. En este estudio, se analizaron 205 muestras de heces de L. culpaeus colectadas, durante noviembre-diciembre de 2016, en un sendero turístico de la Reserva Ecológica Los Ilinizas, la cual está localizada en la cordillera occidental de los Andes ecuatorianos y es representativa de un ecosistema típico de páramo. Se determinaron en total 657 ítems-presa, agrupados en 35 taxones, predominando en frecuencia los mamíferos (48,1%) y las plantas (37,9%). En menor proporción se observaron ítems asociados a grupos de invertebrados (11,6%), aves (1,5%) y reptiles (0,9%). Adicionalmente, se observó que los mamíferos aportaron la mayoría de la biomasa (98,2%) a la dieta del zorro de páramo para esta localidad, siendo el conejo Sylvilagus andinus la presa más importante tanto en términos de frecuencia (26,1%) de ítems, como en aporte de biomasa (95,5%). Estos resultados, reportando a los mamíferos como la principal fuente de alimento para L. culpaeus, coinciden con trabajos previos realizados en la región. La alta frecuencia de plantas sin frutos en las heces colectadas puede estar asociada al consumo accidental durante la depredación activa de mamíferos-presa. No obstante, considerando que las plantas pueden ser ingeridas intencionalmente como fuente de fibra por L. culpaeus, se requiere de la continuación de este tipo de estudios para incrementar nuestro entendimiento sobre los patrones ecológicos de la especie.

Published: February 2025

Debido a la creciente deforestación que sufren las áreas boscosas de Bolivia, los recursos no maderables del bosque como el asaí (Euterpe precatoria), el majo (Oenocarpus bataua) y el cacao (Theobroma cacao), han tomado importancia debido a las propiedades tanto nutricionales, productivas y económicas que aportan a los ecosistemas, por este motivo el estudio analiza las firmas espectrales de las tres especies, en el norte amazónico de La Paz, Bolivia, utilizando tecnologías avanzadas de teledetección. El objetivo principal era mejorar la precisión de la identificación de estas especies, que son vitales para la gestión sostenible de los bosques y los medios de vida de las comunidades locales. Los datos se recopilaron mediante sensores terrestres (Handheld2 ASD) para su validación, junto con imágenes multiespectrales de drones (Phantom 4 Pro, Parrot Sequoia) e imágenes de satélite del Landsat 7, el Landsat 8 y el Sentinel-2B. Se aplicaron a las imágenes de satélite varios métodos de corrección atmosférica, como ATCOR (ERDAS), SEN2COR (SNAP) y el método Dark Object, para garantizar la integridad de los datos. Los resultados demostraron que las imágenes de los vehículos aéreos no tripulados, junto con las del Landsat 7 y el Sentinel-2B, mostraron una mayor correlación con los datos reales obtenidos en tierra con el espectrorradiómetro, mientras que las del Landsat 8 mostraron desviaciones significativas. Esta investigación subraya el papel fundamental de las correcciones atmosféricas apropiadas para identificar con precisión los frutos de los bosques. Los hallazgos contribuyen a una comprensión más amplia del monitoreo ecológico y la gestión de los recursos en los ecosistemas de bosques tropicales, enfatizando el potencial de las tecnologías de teledetección para mejorar los esfuerzos de conservación de la biodiversidad.

Published: February 2025

Los frutos del bosque amazónico boliviano como son las especies de majo, asai y cacao silvestre tienen una gran importancia nutricional y de comercio local; no obstante, pueden sufrir una disminución en los bosques por la tala de árboles, inundaciones y por otro evento climático, lo que los hace vulnerables. Por tal motivo, el objetivo fue identificar plantas madre de alta producción para la conservación de las tres especies frutales. Se caracterizó con protocolos de identificación y determinó la ubicación geográfica de plantas madre en los municipios de Palos Blancos, San Buenaventura e Ixiamas. Se logró identificar plantas madre de las especies en estos municipios. Entre las características se encontró mayor producción frutal de majo y asai en las comunidades de Santa Rosa de Maravilla y Carmen Pecha y de cacao silvestre, en Carmen del Emero.
Análisis técnico y económico de los sistemas agroforestales (SAF`s) que emplean los productores de banano en el municipio de Alto Beni (Análisis de la producción y problemáticas del banano)
Authors: Quelali Mamani Lorenzo
Published: February 2025

La producción y comercialización de banano en la región del Alto Beni es fundamental para la economía local. Este estudio analiza la situación actual de los productores, identificando los principales desafíos que enfrentan y las oportunidades para mejorar la sostenibilidad y rentabilidad de sus cultivos. En ese sentido el estudio considera diferentes variables como el acceso a recursos como un aspecto crucial para los productores. Aunque más de la mitad no están asociados a organizaciones, algunas cooperativas y sindicatos ofrecen beneficios como créditos, insumos y capacitación. Sin embargo, menos de la mitad recibe asesoría técnica, lo que limita su capacidad para mejorar la producción y manejar plagas y enfermedades. Por otro lado, se ha estudiado la comercialización e ingresos donde se ha logrado identificar que la mayor parte de la producción se vende a comerciantes intermediarios, principalmente en La Paz. Los ingresos por la venta de plátano son significativos, pero los productores enfrentan altos costos en insumos y transporte. A pesar de estos desafíos, la producción de plátano sigue siendo una actividad económica vital en la región. Los principales problemas identificados por los productores incluyen: a) Plagas de Animales: Representan el desafío más significativo, afectando la calidad y cantidad de la producción, b) Degradación del Suelo: Un 33.8% de los productores considera que sus suelos están degradados, lo que puede impactar negativamente en los rendimientos, c) Cambio Climático: Este fenómeno agrava los problemas existentes, como sequías y enfermedades. Asimismo, se han identificado desafíos y soluciones ya que los productores enfrentan desafíos como la sequía, el desborde de ríos, y enfermedades como la sigatoka negra. Se sugieren prácticas como el barbecho, la implementación de cultivos asociados, y talleres de capacitación para mejorar el manejo de plagas y la producción.

El compostaje es el proceso de descomposición de los residuos sólidos orgánicos por poblaciones mixtas de microorganismos en condiciones controladas. El objetivo de esta investigación es evaluar el efecto de la adición de microorganismo eficientes en diferentes dosis y la dinámica de sus propiedades físicas y químicas durante todo el proceso de compostaje. Se evaluaron cuatro tratamientos T1 (0L EM/5L H2O), T2 (0.1L EM/5L H2O), T3 (0.5L EM/5L H2O), T4 (1L EM/5L H2O) con 110 días de duración. Los resultados mostraron que el control de temperatura evidencia que el tratamiento con mayor dosis de microrganismo eficientes se mantuvo mayor tiempo en la fase termófila a diferencia del tratamiento testigo (T1) por lo tanto una mayor higienización, en cuanto al pH los tratamientos empiezan con un pH ligeramente ácido y posteriormente aumentan hasta 9-10 para luego descender hasta valores de 9-8 en los tratamientos de T2, T3 y T4. Para la CE los tratamientos T1, T2 y T3 presentan valores superiores a los 5.00 dS m-1, sin embargo, en el tratamiento T4 se presenta valores de 4.78 dS m-1 por lo que se encontraría dentro del rango aceptable por diferentes normativas. En cuanto al carbono orgánico total (COT), se evidencia un mayor porcentaje de mineralización del tratamiento T4 y en menor porcentaje del T1 con respecto al carbono inicial. Para el caso del nitrógeno total se evidencia un ascenso de los tratamientos T2, T3 y T4 con inoculante microbiano por encima del tratamiento testigo atribuyendo eso a las bacterias fijadoras de nitrógeno presentes en los microrganismos eficientes. Finalmente, se puede evidenciar que las emisiones de CO2 son un parámetro importante para identificar la actividad biológica y la estabilidad del compost, así también las emisiones de CO2 producida por la trasformación de COT es directamente proporcional a la temperatura. Esto demuestra que la incorporación de microorganismos eficientes beneficia los procesos de compostaje causando mayor actividad biológica en consecuencia; aumento de temperatura para una adecuada higienización, un incremento del porcentaje de mineralización del COT, mejora de las condiciones de pH y conductividad, una crecida del porcentaje de nitrógeno total y la estabilidad del compost final.

El majo (O. bataua), es una palmera nativa que en estos últimos años ha llamado la atención de productores, empresas y el gobierno central de Bolivia, por el potencial productivo que presenta debido a sus propiedades químicas, características nutricionales y demanda en el mercado nacional, lo que llevó a realizar el presente estudio, con el objetivo de conocer la incidencia de cinco tipos de abejas nativas (Trigona sp., Partamona sp., T. angustula, Oxytrigona sp., Plebeia sp.), en la polinización de frutos de majo. Se utilizó la siguiente metodología: a) identificación del meliponario con las colmenas establecidas, b) análisis espacial de la distribución de palmeras de majo, c) análisis del polen extraído y d) descripción y discusión de los resultados obtenidos. Los resultados realizados durante la identificación de meliponarios indican que se encontró más granos de polen en la muestra de la colmena de la especie Trigona sp. (promedio de 7 granos polen muestra 10 u/l), seguido por el género Plebeia sp. (promedio de 3 granos polen muestra 10 u/l), seguido de Oxytrigona sp. (promedio de 2,4 granos polen muestra 10 u/l), seguido de T. angustula (promedio de 2,2 granos polen muestra 10 u/l). En el género Partamona sp. se pudo observar muy pocos granos polen y en algunas repeticiones ninguno. Siendo este un estudio de línea descriptiva, es necesario continuar con los análisis en diferentes épocas de recolección y tipos de abejas meliponas.

Authors: Francisco Sánchez-Viesca  , Reina Gómez Gómez
Published: February 2025

Morphine is a highly efficient analgesic and is still the stronger painkiller today, but also has strong addictive properties. The misuse, due to the euphoria that produces, makes indispensable have at hand a rapid and simple chemical test for morphine identification, like the assay studied in this communication. It employs potassium ferricyanide and ferric chloride as reagents that in contact with morphine gives rise to Turnbull’s blue, the blue colour observed in the test. It is based in a redox process that produces ferrous ferricyanide (reduction step) and 2,2’bimorphine (oxidation step), via a free radical mechanism and a coupling reaction.

Resumo: O vírus da imunodeficiência humana (HIV) é um dos principais desafios para a
saúde pública mundial. A terapia antirretroviral (TARV) iniciada precocemente está
associada ao bom prognóstico da doença, porém as mutações genéticas podem impactar a
eficácia dos antirretrovirais (ARVs). Os primeiros casos de HIV-1 estavam mais
relacionados aos homens, porém a transmissão heterossexual é um dos fatores responsáveis
pelo o envolvimento das mulheres na epidemia. Foi realizado um estudo envolvendo 1278
casos de pacientes adultos jovens (18-49 anos) que viviam com HIV-1 na região
metropolitana de São Paulo que tiveram solicitação de genotipagem enviadas ao Núcleo de
Doenças Sanguíneas e Sexuais (NDSS) do Centro de Virologia do Instituto Adolfo Lutz no
período de 10 anos (2014-2023). Dentre o total de casos 548 eram mulheres e 730 homens,
dos quais 78% das mulheres e 83% dos homens (p=0,0082) apresentaram mutações
(principais e/ ou acessórias) aos ARVs. Dos casos que apresentaram mutações, 26% das
mulheres e 28% dos homens foi para Inibidores de Protease (IP) (p=0,2709) 79% das
mulheres e 87% dos homens para Inibidores Análogos de Nucleos(tí)deos (NRTI)
(p<0,0001) e 58% das mulheres e 80% dos homens para Inibidores Não Análogos de
Nucleos(t)ídeos (NNRTI) (p=0,0013). Dentre as 548 mulheres analisadas, 39 (7%), eram
gestantes das quais 22 apresentaram alguma mutação associadas ao vírus e, dentre elas 17
mostraram algum grau (implicação clínica) de resistência aos antirretrovirais. Os resultados
indicam que, como esperado, há alta prevalência de mutações (principais e acessórias)
associadas à resistência aos ARVs em pacientes em falha terapêutica, sendo maior nos
homens. Os dados destacam a importância do monitoramento contínuo da carga viral,
essencial para identificar falhas terapêuticas e possibilitar a realização da genotipagem,
garantindo que as adaptações terapêuticas sejam implementadas.
SURTOS DE TRANSMISSÃO HÍDRICA ENVOLVENDO VÍRUS ENTÉRICOS: EPIDEMIOLOGIA E IMPACTO EM SAÚDE PÚBLICA NO BRASIL, 2000-2023
Authors: Santana Micheli de Oliveira , Assis Jaqueline Calça
Published: February 2025

Resumo: A água pode ser contaminada por microrganismos patogênicos, como bactérias,
vírus e parasitas, principalmente devido ao esgoto não tratado, resultando em doenças
graves. Os vírus entéricos humanos são responsáveis por muitas dessas infecções. O controle
sanitário deve considerar o perfil epidemiológico das Doenças de Transmissão Hídrica e
Alimentar (DTHA), e os registros de vigilância são fundamentais para monitorar a
frequência desses patógenos ao longo do tempo. O objetivo foi analisar o perfil
epidemiológico dos surtos de doenças causadas por vírus transmitidos através de água
contaminada e descrever as principais causas associadas a esses eventos no Brasil no período
de 2000 a 2023. O presente estudo é uma revisão bibliográfica sobre surtos de DTHA no
Brasil, com foco na transmissão hídrica por vírus entéricos, no período de 2000 a 2023.
Foram selecionados estudos a partir de fontes como o Ministério da Saúde (MS), PubMed,
SciELO, Google Acadêmico e ScienceDirect. A análise dos dados revelou que a distribuição
dos surtos de DTHA no Brasil está relacionada à desigualdade no acesso ao saneamento
básico, com a Região Nordeste concentrando a maior parte dos surtos (56%), seguida pela
Sudeste (38%). Observou-se uma diminuição no número de casos ao longo dos anos,
possivelmente atribuída à introdução de vacinas e a melhorias pontuais em infraestrutura.
Apesar dessa redução, a gravidade do problema persiste, reforçando a necessidade de
investimentos contínuos em saneamento básico e no controle da qualidade da água para
prevenir novos surtos e proteger a saúde pública.
PERFIL EPIDEMIOLÓGICO DOS SURTOS DE DOENÇAS DE TRANSMISSÃO HÍDRICA E ALIMENTAR CAUSADOS POR SALMONELLA spp., BRASIL, 2004 A 2023
Authors: Guedes Taimara Câmara , Peresi Jacqueline Tanury Macruz
Published: February 2025

Resumo: Dentre as doenças transmitidas por água e alimentos (DTHA) registradas no
mundo, Salmonella está entre os quatro maiores agentes envolvidos. Este estudo teve por
objetivo avaliar o perfil epidemiológico dos surtos de DTHA por Salmonella no período de
2004 a 2023, no Brasil. Trata-se de trabalho de revisão elaborado com base no banco dados
público do Ministério da Saúde, em artigo científicos, livros, manuais e portais eletrônicos,
sendo utilizadas as seguintes bases de dados: PubMed, MEDLINE, LILACS, SciELO,
Biblioteca Virtual de Saúde e Google Acadêmico. Dos 13.954 surtos de DTHA causados
por diversos agentes etiológicos no período avaliado, 1.031 (7,4%) foram ocasionados por
Salmonella, totalizando 26.522 doentes. Em 73 (7,1%) dos surtos foi identificado o sorotipo,
sendo S. Enteritidis responsável por 54 (74%) deles. Os veículos de transmissão mais
envolvidos em relação aos 1.031 surtos foram ovos/produtos à base de ovos (34,6%),
seguido de alimentos mistos (16,3%) e múltiplos alimentos (13,4%). Os locais de maior
ocorrência dos surtos foram residências (46,2%), seguido de restaurantes/padarias e
similares (20,1%) e outras instituições, alojamentos e trabalho (8,9%). A região Sul registrou
o maior número de episódios (64,5%), seguida pelo sudeste (16,7%) e nordeste (12,5%). Em
74% do total das ocorrências não houve a confirmação por meio de análise dos alimentos.
Diante do exposto enfatiza-se o impacto da Salmonella como agente de DTHA e a
importância do conhecimento do perfil epidemiológico destes agravos para melhor
compreender a proporção dessa problemática no país e para implantação/implementação de
Programas de prevenção e controle destas doenças.
UMA VISÃO CRÍTICA COM O OBJETIVO DE COMPARAR AS VACINAS BEXSERO E TRUMENBA PARA NEISSERIA MENINGITIDIS B MUNDIALMENTE UTILIZADAS
Authors: Oliveira Giovanna Santos , Gaspari Elizabeth
Published: February 2025

Resumo: A meningite é uma inflamação das meninges e representa um grande desafio de
saúde pública devido à sua gravidade e diversidade de agentes etiológicos. O
desenvolvimento de vacinas para o sorogrupo B é desafiador. Apesar disso, as vacinas
Bexsero® e Trumenba® demonstram eficácia contra esse sorogrupo, proporcionando
proteção relevante. Este estudo visou comparar essas vacinas, avaliando a relevância de sua
inclusão no calendário vacinal do Brasil. A pesquisa utilizou a base de dados PubMed, site
oficiais do governo e bulas dos fabricantes. Ambas as vacinas Bexsero® e Trumenba® são
eficazes contra o meningococo B. No Brasil, estão disponíveis apenas no setor privado, e
sua inclusão no SUS enfrenta desafios de custo e priorização, apesar da importância para a
saúde pública. A meningite do sorogrupo B atualmente inclui vacinas como Bexsero® e
Trumenba®. Acreditamos que a inserção no SUS terá que superar barreiras de custo e
prioridade. Como é de conhecimento a integração público-privada e campanhas são
essenciais para ampliar o acesso e reduzir casos no Brasil.
AVALIAÇÃO DO TEOR DE GORDURA TOTAL EM BISCOITOS: IMPLICAÇÕES PARA A SAÚDE DO CONSUMIDOR
Authors: Souza Maria Angélica Loures , Kus-Yamashita Mahyara Markievicz Mancio
Published: February 2025

Resumo: Muito consumido pela população, em especial por crianças, o biscoito utiliza
vários tipos e quantidades de óleo como matéria prima no processamento, que determinam
a qualidade do produto final. Os tipos de gordura usados nos biscoitos são prioritariamente
ácidos graxos saturados e trans, que na maior parte estão relacionados com o risco de
desenvolvimento de doenças crônicas não transmissíveis. O objetivo do trabalho foi verificar
os teores de gorduras totais (GT) em biscoitos entre 2009 a 2016, e analisar a evolução no
período. Foram avaliados 203 laudos técnicos de amostras de biscoitos, nas seguintes
categorias: salgado, água e sal, cream cracker, polvilho e biscoito doce. Pode-se verificar
que há uma tendência de diminuição da quantidade de gordura total nos alimentos
industrializados ao longo dos anos, entretanto o impacto na população brasileira, aliado ao
alto consumo destes produtos, e a ausência de dados de gordura total para estes alimentos
em anos mais recentes, ainda, não pode ser observado O alto consumo de gordura em
produtos industrializados agrava o risco de desenvolvimento de DCNT. Assim, as
informações corretas da rotulagem nutricional pode ser uma estratégia de prevenção de
doenças, e a principal ferramenta de direito na escolha de produtos conscientes atrelada a
análise laboratorial frequente como uma defesa a saúde do consumidor.
Biological Monitoring of Surface Water Bodies of the Adriatic Sea Basin in Bosnia and Herzegovina-An Example
Authors: Dedić Anita
Published: February 2025

According to the application of the European Water Framework Directive, bioassessment of surface water bodies is one
of the most important approaches to provide the deterioration of ecosystems and achieve environmental sustainability.
Hydromorfological alternation, nutrient enrichment driven by human activities are the main factors for the ecological
compromise of freshwater ecosystems. During the 2022 we done research and bio assessment in 40 water bodies in the
Adriatic Sea Basin, and it is included monitoring of
i. physico- chemical,
ii. chemical,
iii. hydro-morphological, and
iv. biological factors.
Mostly of our investigated water bodies were in category of good or high ecological status or maximum or good ecological
potential. Despite the satisfactory conditions we have been noting new water challenges (e.g. eutrophication, water blooms,
salinization, invasive species, biodiversity declining) lately. Bioassessment in surface water bodies could be used in a risk
assessment framework to identify levels of pollution or contamination, and guide environmental decision making.
