La ocupación lima en el valle de Lurín: en los orígenes de Pachacamac monumental
Authors: Makowski Krzysztof , Vallenas Alain
Published: May 2023

Las excavaciones llevadas a cabo por los autores en dos lugares claves del complejo monumental de Pachacamac, al pie de la fachada sur del Templo Viejo y debajo del vestíbulo de la entrada principal al Templo del Sol, han permitidodeterminar con precisión, la cronología relativa del inicio de obras de construcción, emprendidas durante el Periodo Intermedio Temprano, en el área del famoso santuario, ubicado sobre la margen izquierda del río Lurín, en los suburbios de Lima. El material cerámico asociado a los niveles de ocupación tiene las mismas características tecnológicas, formales e iconográficas que la cerámica Lima Medio (Lima 4-5 según Patterson (2014[1966]) en los valles de Chancay y Chillón, así como en Ancón. Cambios simultáneos, profundos, y de gran escala, se hacen presentes durante las fases Lima Medio en la Costa Central del Perú. Las tecnologías de producción de cerámica, su decoración, las técnicas de construcción, las formas de arquitectura, y los rituales funerarios, originarios de la cuenca de Chillón y de Ancón fueron adoptadas por laspoblaciones de Rímac y Lurín. Estas evidencias hacen reforzar la hipótesis que luego de la conquista de los valles bajos de Rímac y Lurín se está formando una entidad política regional multivalle con características de jefatura compleja y/o del «estado andino». Pachacamac lima no tuvo características de un centro administrativo con zonas urbanas residenciales, sino más bien las de un centro ceremonial local, posiblemente de rango subalterno, a juzgar por la comparación con Maranga, Pucllana y Cajamarquilla.
Sexual Violence in Italy: Are Women Victims or Responsible?
Authors: Ostuni Adriana , Sacco Giuseppina , Sacco Pietro , Zizza Alfonso
Published: May 2023

Sexual violence is the imposition of unwanted physical contact obtained by force, manipulation, or coercion. This kind of violence, which is detrimental to the dignity of the person who suffers it, causes deep psychic as well as physical wounds in the victim and is the most widespread violation of human rights in all countries and cultures. This paper tries to investigate whether the stereotype of women being responsible for the sexual violence they suffered is dominant in our society. The study of this stereotype has been addressed through the survey "Gender roles stereotypes and the social image of sexual violence" carried out by ISTAT in 2019 (referred to 2018) on the adult, male, and female, population aged between 18 and 74. With regard to the stereotypes proposed in the survey, the results have shown that there is a clear contrast between young and older women and between women with a higher educational qualification and those with an elementary school degree. At the regional level, however, the contrast is between Central-Northern regions and Southern Italy: in five of the eight regions belonging to the Southern division, the most widespread stereotype is that the responsibility for sexual violence is attributable to women.

Authors: Leal-Lara Daniel-David , Barón-Velandia Julio , Rocha-Calderón Camilo-Enrique
Published: May 2023

La detección temprana de enfermedades en las plantas mediante técnicas de inteligencia artificial, ha sido un avance tecnológico muy importante para la agricultura, ya que por medio del aprendizaje automático y algoritmos de optimización, se ha logrado incrementar el rendimiento de diversos cultivos en varios países alrededor del mundo. Distintos investigadores han enfocado sus esfuerzos en desarrollar modelos que permitan apoyar la tarea de detección de enfermedades en las plantas como solución a las técnicas tradicionales utilizadas por los agricultores. En esta revisión sistemática de literatura se presenta un análisis de los artículos más relevantes, en los que se usaron técnicas de procesamiento de imágenes y aprendizaje automático, para detectar enfermedades por medio de imágenes de las hojas de diferentes cultivos, y a su vez se lleva a cabo un análisis de interpretabilidad y precisión de estos métodos, teniendo en cuenta cada fase las fases de procesamiento de imágenes, segmentación, extracción de características y aprendizaje, de cada uno de los modelos. De esta manera se evidencia vacío en el campo de la interpretabilidad, ya que los autores se han enfocado principalmente en obtener buenos resultados en sus modelos, más allá de brindar al usuario una explicación clara de las características propias del modelo.
Using Decision Trees to Predict Critical Reading Performance.
Authors: Timaran-Buchely Andrea , Timarán-Pereira Silvio-Ricardo , Hidalgo-Troya Arsenio
Published: May 2023

In Colombia, all undergraduate students, regardless of the professional training program they take, must complete the general competencies sections of the Saber Pro exam that include Critical Reading, Quantitative Reasoning, Citizen Competencies, Written Communication, and English. This paper presents the application of the classification technique based on decision trees in the prediction of the performance in the Critical Reading section presented by the students of the Pontificia Universidad Javeriana Cali in the years 2017 and 2018. The CRISP methodology was used. From the socioeconomic, academic and institutional data stored in the ICFES databases, a data repository was built, cleaned and transformed. A mineable view composed of 2052 records and 17 attributes was obtained. The J48 algorithm of the Weka tool was used to build the decision tree. The score obtained in the Critical Reading section of the Saber Pro exam was taken as a class. According to the results obtained, the Philosophy, Applied Mathematics, and Medicine programs stood out for having the best performance in this test. Among the predictive variables associated with performance in the Critical Reading skill are the faculty, the age group and the student's transportation index, as three important variables related to the good or low academic performance of the students of the Universidad Javeriana Cali. The knowledge generated in this research is constituted in quality information to support the decision-making process of the university directives in order to improve the quality of the higher education offered in this institution.
Agile Functional Requirements Modeling from Goal-Oriented Requirements Engineering: A Systematic Mapping Study
Authors: Muelas-Muelas Francy-Idaly , Narváez-Jiménez Laura-Camila , Pardo-Calvache Cesar-Jesús
Published: May 2023

During the last two decades, the application of Goal-Oriented Requirements Engineering has increased in software projects, mainly because this approach is useful during the requirements analysis process and supports the realization of tasks such as requirements elaboration, validation, and planning, and can be used as part of the system life cycle, e.g. architecture and design of behavioral processes, coding, testing, monitoring, adaptation and evolution. Several approaches addressing goal-oriented requirements have already been proposed. Currently, there are several concerns about how to correctly adopt and implement it in current industrial contexts, such as agile approaches and, more specifically, its integration with user stories and acceptance criteria. This study presents a compilation of the current knowledge on adopting GORE in agile requirements specification through user stories and their acceptance criteria. A systematic mapping study guided by ten research questions was conducted, and nine primary studies were selected considering the selection criteria. The results obtained show some initiatives as goal-oriented modelling languages in different proposals for transforming goal-oriented models into user stories, among them: i* (i-star), Tropos, KAOS, GRL, AOM, and Goal Net. This study provides a solid basis for classifying existing and future approaches in the application of GORE. Researchers and practitioners can use this mapping to identify existing technical/research gaps to better address and assess their own contributions or understand existing ones.
Instructor Leadership and the Community of Inquiry Framework: Applying Leadership Theory to Higher Education Online Learning
Authors: Meech Sally , Koehler Adrie
Published: May 2023

Higher education institutions continue to invest in online learning, yet research indicates instructors often lack experience, preparation, and guidance for teaching online. While instructor leadership is essential for meaningful online learning, few studies have investigated online instructors’ leadership behaviors. This study offers new insights into the conceptual and empirical alignment between instructor leadership, as interpreted through the dual lenses of organizational leadership theory and the Community of Inquiry (CoI) framework, proposing instructor leadership as foundational to the teaching and learning experience in a CoI. Specifically, the convergent mixed methods study investigated students’ (N = 87) and instructors’ (N = 7) perceptions of instructor servant leadership (SL) behaviors in an online graduate-level course designed to facilitate a CoI. Results demonstrate instructor SL behaviors were perceived differently by students and instructors, instructors’ self-perceptions were generally higher than students’ perceptions, and students’ perceptions of instructor SL were positively correlated with their satisfaction with the course and instructor. Implications offer insights into instructor leadership behaviors important for developing instructor leadership presence to facilitate meaningful learning and student satisfaction in higher education online learning.

Engaging with young people: a reflection on groupwork experiences in the light of Wilfred Bion’s early insights into group process.
Authors: Naylor Gillian
Published: May 2023

This article seeks to explore the work of Wilfred Bion in the early stages of his therapeutic explorations of the group process. Focusing on examples from his work in the 2nd World War, the author draws on 3 key themes which epitomise Bion’s thinking; striving for the leaderless group, relinquishing the leadership role and studying the group itself. These themes are then used to inform a reflection of the author’s experiences working with groups of young people who for a variety of reasons are reluctant to engage. Conclusions are drawn regarding the enduring relevance of Bion’s insights and the value that may be gleaned by stepping back from the leadership role and from ensuring that evaluation of group activity includes engaging with not just the ‘what‘, but also the ‘how‘ and ‘why‘ of the experience.

The Perception of Leaders: A Competitive Test of Social Exchange Theory and Equity Theory
Authors: Dick Daniel T , Henningsen David Dryden
Published: May 2023

Social exchange theory and equity theory were used to examine the perception of leaders in a small group context.  Participants (n = 154), involved in a semester long group project  assessed their leaders  contributions to the task and maintenance of the group using measures gauging social exchange and equity forces.   These measures were regressed onto desire to work with the leader again in the future. Overall, the results indicate greater support for social exchange theory.
La participación en la intervención grupal con adolescentes y jóvenes: entre el control y el empoderamiento
Authors: Ducca Cisneros Linda
Published: May 2023

Participation is a concept that is current in most social intervention projects with young people and adolescents. However, there are tensions in the daily practice of social intervention to promote participation. This article explores the tensions between the control and empowerment functions from the point of view of participants in social intervention programs with different characteristics.Through a qualitative methodology – discussion groups and process groups – the group practice with young people and adolescents is systematized from a critical perspective that aims to encourage reflection on the objectives of the practice and thus contribute to generate experiences that promote participation. It is concluded that the point of view of young people and adolescents can provide keys to overcome this dichotomy. Emphasizing a rights-based approach that contributes to social inclusion processes need not be at odds with the promotion of critical awareness and citizen participation in everyday spaces. Consideration and listening are the first steps in promoting participation.
La participación es un concepto que se encuentra vigente en la mayoría de los proyectos de intervención social con jóvenes y adolescentes. Sin embargo, existen tensiones en la práctica diaria de la intervención social para poder promover la participación. En este artículo se exploran las tensiones entre la función de control y de empoderamiento desde el punto de vista de participantes de programas de intervención social con características diferentes. Mediante una metodología cualitativa – grupos de discusión y grupos de proceso – se sistematiza la práctica grupal con jóvenes y adolescentes desde una perspectiva crítica que pretende fomentar la reflexión acerca de los objetivos de la práctica y por ende contribuir a generar experiencias que promuevan la participación. Se concluye que el punto de vista de jóvenes y adolescentes puede aportar claves para superar esta dicotomía. Poner el énfasis en un enfoque de derechos que contribuya a procesos de inclusión social, no tiene por qué estar reñido con el fomento de la conciencia crítica y la participación ciudadana en los espacios cotidianos. La consideración y la escucha es el primer paso para el fomento de la participación.

Introduction: Validating health-education materials prevents the dissemination of erroneous messages and enhances the effectiveness of health-promotion initiatives. Objective: To describe the validation process for five educational materials pertaining to an online course on the promotion of water consumption among Mexican adolescents. Methodology: One group of 13-15 experts (technical validation) and another of 13-39 adolescents (population validation) reviewed three infographs and two videos using digital tools. Five criteria were established for the evaluation: appeal, clarity, identification, acceptance and inducement to action. A performance index was developed based on two categories: strong or weak compliance with each criterion. Successful compliance was determined when 70% or more of responses fell within the strong-compliance category. Results: Between 80% and 100% of the experts and adolescents rated all materials in the strong-compliance category for appeal, acceptance, clarity and inducement to action. For identification, however, the experts accorded the three infographs low scores, with similar results obtained from the adolescents for the three infographs and one video. Conclusions: Validation of the course materials allowed for identifying their strengths and weaknesses, as well as for ascertaining their usefulness in promoting water consumption among Mexican adolescents.

Entre biomas e embriões
Authors: Godoy Adriano
Published: May 2023

Este artigo tem como ponto de partida a composição imagética do baldaquino da “vida” na Basílica Nacional de Nossa Senhora Aparecida (Aparecida, SP). Recorrendo metodologicamente à sobreposição entre religião e mídia, considero aquele templo um lugar privilegiado para a investigação antropológica sobre o catolicismo institucionalizado. Assim, para analisar as formas pelas quais a “vida” é imaginada religiosamente, viso explorar as redes de engajamento que constroem e dão as múltiplas formas da “vida” no catolicismo brasileiro. Nessa direção, faço uma seleção de algumas das formas pelas quais essa “vida” é materializada religiosamente em outros contextos brasileiros nos quais biomas e embriões também se tornam protagonistas imagéticos: os ativismos socioambientais e os ativismos antiaborto. Longe de almejar definir cosmologicamente a “vida” enquanto uma categoria católica metafísica, tenho o intuito de mapear as disputas que certas imagens são capazes de mediar no ativismo católico contemporâneo – seja pela sua sacralidade, seja pela sua politização.

A proposta de comunicação deste “VI Encontro de História da Arte” teve como objetivo principal a apresentação do material iconográfico sobre o imperador D. Pedro I, que foi recentemente adquirido em Portugal. Este material está distribuido nos três volumes do livro intitulado “D. Pedro I - Estudo Iconográfico”. O estudo foi obra do colecionador das artes polonês Stanislaw Herstal e conta com um acervo de aproximadamente oitocentas imagens devidamente descritas e distribuídas em aproximadamente mil e quinhentas páginas. Este material dá subsídios para que se faça uma investigação da construção da imagem pública de D. Pedro I e de como suas representações artísticas elucidaram a relação entre arte e poder no breve período em que viveu e, em alguns casos, após sua morte.
As coleções Matarazzo no acervo do MAC USP e a pintura moderna no Brasil
Authors:   Universidade de São Paulo, Magalhães Ana Gonçalves
Published: May 2023

Em A Arqueologia do Saber, Michel Foucault fez a crítica à história das mentalidades em sua visão do discurso da história por via daquilo que os historiadores da escola dos Annales designavam como a “longa duração” - e que, portanto, implicava trabalhar com a noção de continuidade -, para propor uma análise da disciplina que pudesse incorporar e interpretar a descontinuidade. Foucault começava analisando as regularidades discursivas, isto é, na elaboração mesma do discurso (procedimentos do historiador), e sobre a formação do objeto do discurso ou o objeto de estudo do historiador, e de como a descrição do objeto levava necessariamente à construção do discurso. Em última análise, ele partia da aporia do discurso historiográfico em trabalhar com a noção de descontinuidade, ao mesmo tempo em que ela já estava dada pelo próprio objeto de estudo do historiador.
Vocabulário Landi: um álbum de ornamentos para Belém
Authors:   Universidade Federal do Pará, Oliveira Domingos Sávio de Castro
Published: May 2023

A arquitetura da Belém do Grão Pará da segunda metade do século XVIII é pontuada pela obra do arquiteto italiano Antônio José Landi responsável pelo projeto e construção ou reforma de edificações que marcam a paisagem da cidade até os dias atuais. A formação de Landi na Academia Clementina de Bolonha, da qual também foi professor, propiciou-lhe o contato com um grupo de artistas, os Galli da Bibiena, famosos arquitetos e cenógrafos, cuja linguagem e repertório ornamentais influenciaram sua produção, o que pode ser visto nos desenhos que produziu para edificações em Belém. A linguagem bibienesca, considerada uma variação mais flexível do rococó, ou barrochetto, recusou a rigidez das ordens da arquitetura clássica e privilegiou a imaginação decorativa.

Ainda que se encontrem frente às câmeras fotográficas, os sujeitos não se revelam, brincam entre disfarces, ironicamente simulam o normativo, uma simplificação do que se encontraria em jargões pejorativos, emprestam seus rostos sérios para servirem de molduras para enormes bigodes. Assim se dá o trabalho de Catherine Opie, artista americana cuja produção emerge no campo da arte em no final da década de oitenta, inicio dos anos 90. De sua vasta produção, aqui serão abordados apenas os retratos realizados em estúdio.
Arte relacional e regime estético: a cultura da atividade dos anos 1990
Authors:   Universidade de São Paulo, Fabbrini Ricardo Nascimento
Published: May 2023

O artigo mostra que na arte relacional, na expressão de Nicolas Bourriaud, dos anos 1990, é visível a tentativa de embaralhar arte e vida, o que a remete ao imaginário das vanguardas artísticas do século 20. Procura, contudo, distinguir o projeto moderno de superação da relação entre arte e vida desta proposta de “arte colaborativa” que tomamos como sintoma da arte contemporânea. Seu objetivo é assim examinar se essas “práticas colaborativas e interdisciplinares” que se aproximam do mundo da vida - segundo também Jacques Rancière e Hans Obrist - articulam os elementos do presente no gesto estético ou na forma artística - de modo a relacionar, na metáfora, estética e política - ou se essas práticas, ao contrário, atestam a neutralização da poética e o desvanecimento da política. Para tanto indagamos, a partir de Jean Galard, se esses espaços substitutivos podem funcionar efetivamente como elementos de recomposição dos espaços políticos, ou se eles correm o risco de assumirem a função de seus substitutos paródicos; ou seja: se na tentativa de suprir a ausência de políticas sociais, o que teríamos nos espaços de arte relacional é uma sociabilidade glamourizada, fictícia - um simulacro da sociabilidade dita real porque fundada na imprevisibilidade e nos conflitos.
Opening mathematics texts: A critical discourse analysis of probability problems in mathematics textbook
Authors: Bustang Bustang
Published: May 2023

[English]: This article investigates the nature of probability problems presented in mathematics textbook using the socio-political perspective and critical discourse analysis drawn from well-known critical linguists Norman Fairclough. Specifically, the paper analyzed how the students are positioned by the problems presented in the text, to find out the role of authors and student readers, and to gain insight about the possible consequences for students. Drawing on Fairclough's three-dimensional model for critical discourse analysis as a framework for studying the relationship between the written text of probability problems in the textbook, the associated discursive practices, and the social practice to which the discursive practices form part, the article argues that the textbook authors tend to be authoritative by directing students about what to do and how to do the probability (mathematical) activities. The analysis also shows that the use of real-word problems in the text points out the attempts of the authors to present the probability concepts more relevant and accessible to the student readers. The article demonstrates the usefulness of Fairclough's three-dimensional model as a framework for analyzing probability problems presented in the mathematics textbook.
[Bahasa]: Artikel ini menyelidiki sifat masalah peluang yang disajikan dalam buku teks matematika dengan menggunakan perspektif sosio-politik dan analisis wacana kritis yang diambil dari ahli bahasa kritis terkenal Norman Fairclough. Secara khusus, makalah ini menganalisis bagaimana siswa diposisikan oleh masalah yang disajikan dalam teks, untuk mengetahui peran penulis dan siswa sebagai pembaca, serta untuk mendapatkan wawasan tentang konsekuensi yang mungkin terjadi pada siswa. Merujuk pada model tiga dimensi Fairclough untuk analisis wacana kritis sebagai kerangka kerja untuk mempelajari hubungan antara teks tertulis dari masalah peluang dalam buku teks, praktik diskursif yang terkait, dan praktik sosial yang merupakan bagian dari praktik diskursif, artikel ini menunjukkan bahwa penulis buku teks cenderung otoriter dengan mengarahkan siswa tentang apa yang harus dilakukan dan bagaimana melakukan kegiatan berkaitan dengan konsep peluang (matematika). Analisis juga menunjukkan bahwa penggunaan masalah berbasis kehidupan sehari-hari dalam teks menunjukkan upaya penulis untuk menyajikan konsep peluang yang lebih relevan dan dapat diakses oleh siswa. Artikel ini menunjukkan kegunaan model tiga dimensi Fairclough sebagai kerangka kerja untuk menganalisis masalah peluang yang disajikan dalam buku teks matematika.
The contribution of the hidden curriculum to gender inequality in teaching and learning materials: Experiences from Tanzania
Authors: Losioki Bertha Erasto , Mdee Hemed Karani
Published: May 2023

This study aimed to examine the contribution of the hidden curriculum to gender inequality in teaching and learning materials. Despite the efforts to have an official curriculum through school textbooks and learning materials. The hidden curriculum continued to encourage gender inequality through teaching and learning materials.  The study examined the content and portrayal of males and females in primary school social studies textbooks. The study used a qualitative research approach and the documentary review method was used to gather information from books, published articles, and policy documents. The findings show that there was an improvement in addressing gender inequality in textbooks and learning materials. The findings show that the visibility and representation of females in textbooks have increased. However, gender roles were portrayed in stereotypical ideas and images that encourage gender bias.  The study concluded that teaching and learning materials encourage a hidden curriculum that facilitates the underrepresentation of females and males in textbooks. Therefore, the Government in collaboration with the relevant authorities should ensure that the development of teaching and learning materials considers gender-responsive content and gender balance in role allocation. There is a need to increase awareness among reviewers and book authors on gender sensitivity in the preparation of teaching and learning materials in order to ensure adherence to gender equality principles.
Substitution of Hibiscus sabdariffa with Curcuma longa in the Diets of Clarias gariepinus and the Effects on the Growth, Nutrient, and Hematobiochemistry
Authors: Enyidi Uchechukwu Dennis , Ayogu I.
Published: May 2023

Phytogenic feed additives are plausible alternatives to antibiotics and serve as growth promoters in aquafeed. This research aims at finding the effects of varying inclusions of natural antioxidants like hibiscus (Hibiscus sabdariffa L.) and turmeric (Curcuma longa) on the growth, hematology, and nutrient utilization of Clarias gariepinus after 60 days feeding. This research used six feeds labeled as F1- F6 that varied in the composition of Curcuma longa and Hibiscus sabdariffa. The weight (g) inclusions of C. longa and H. sabdariffa were as follows, F1 0:250, F2 50:200, F3 100:15, F4 150:100, F5 200:50 and F6 250:0. Juvenile African catfish stocked at 9 catfish per 15L aquaria per 3 replicate aquariums (27/treatment feed) were fed for 60d. The catfish fed with F1 (250g H. sabdariffa) had the best specific growth rate 5.76±0.04 % day-1, lowest feed conversion ratio 1.01±0.01, weight gain 31.65±0.13 g, and protein efficiency ratio 0.96±0.07. The growth of African catfish increased with the increasing inclusion of hibiscus supplements. Hematobiochemical parameters ALT, AST was better for catfish fed high hibiscus supplements. We noticed that hibiscus inclusion was inversely proportional to cholesterol and total triglycerides levels of fish. The deposit of adipose tissues in the catfish was higher, with increasing inclusion of hibiscus than turmeric supplement.

Published: May 2023

Tilapia fish have a salinity tolerance of 0 to 10 ppt. However, the increase in salinity causes a decrease in the growth rate of these fish. In addition, the rapid maturation of the gonads causes this fish to experience a slowdown in growth. This study aimed to know the effect of giving Melastoma malabathricum extract on the growth performance of tilapia fry reared in brackish water. The study consisted of treatment with 0, 1, 3, and 6 g/kg of feed with three replications of M. malabathricum leaf extract. M. malabathricum leaf extract was mixed in feed with a CMC concentration of 2%. Feed is given as much as 3% body weight twice a day. Observations of growth performance were carried out every seven days, and the amount of feed was readjusted based on the results of sampling fish weight. The study was conducted for 70 days using brackish water with a salinity of 8 ppt. Based on the study results, it was found that the highest growth of tilapia fry at the end of the study was found in the treatment of 1 g/kg feed. The same thing was also found in measuring feed efficiency, survival, and specific growth rate. It indicated that the best concentration of M. malabathricum leaf extract in supporting the growth performance of tilapia fry was 1 g/kg feed.

Authors: Febriani Eka Fitria , Widodo Maheno Sri , Faqih Abdul Rahem
Published: May 2023

Red ginger (Zingiber officinale var. Rubrum) as one of the Indonesian spices has so many important roles, especially in the health sector as a medicinal plant, which has many active compounds including phenols, alkaloids, flavonoids, steroids and tannins. From some researches before, we can know that plants which grow in different places or locations have different tolerances generally. That statements can show that they have different content in their constituent metabolites definitely. Therefore, phytochemical analysis is needed to analyze the content of each red ginger (Z. officinale var. Rubrum) from three locations such as Red ginger (Z. officinale var. Rubrum) from Batu, Malang (RGB), Plaosan, Magetan (RGP) and Simalungun, Medan (RGS) to analyze each content its contains. Also, perform LC50 was needed for analyzing its effect on Zebra fish (Danio rerio) as a model fish. For this research, we use an experimental study with a Completely Randomized Factorial Design (CRFD) method that has two independent variable such as different dosage and type of red ginger (Z. officinale var. Rubrum). In this study, from five dosages (10 mg/l; 20 mg/l; 30 mg/l; 40 mg/l; 50 mg/l) and three types of red ginger (Z. officinale var. Rubrum) treatment, it found that the highest mortality and lowest survival rate were at the highest dosage (50 mg/l) in RGB and extreme increase or decrease in the curve is found in RGP treatment.

The disease that causes many deaths in cantang grouper is Viral Nervous Necrosis. One of the most effective ways is by giving vaccines to fish. This study aims to develop a recombinant protein Chlorella vulgaris vaccine with the addition of an adjuvant to increase the immunity of cantang grouper infected with VNN. The method used was experimental with a Completely Randomized Design (CRD) consiting of seven treatments and three replications, namely (K+) cantang grouper infected with VNN, (T1) Healthy cantang grouper was given 33 µl of vaccine, (T2) Healthy cantang grouper was given vaccine of 66 µl, (T3) Healthy cantang grouper was given 112 µl of vaccine, (T4) Healthy cantang grouper was given 33 ul of vaccine and then tested against Viral Nervous Necrosis, (T5) Healthy cantang grouper was given 66 ul vaccine and then tested against Viral Nervous Necrosis, (T6) Healthy cantang grouper was given 112 ul vaccine and then tested against Viral Nervous Necrosis. The fish used were 8-10 cm in size and were reared for 56 days. The results showed that the Chlorella vulgaris protein recombinant vaccine with the addition of adjuvant gave a very significant effect on the immunity of cantang grouper infected with VNN with the best dose of 33 µl (T4) seen from the relative protection level (RPS) (75,6%), survival of cantang grouper (78%) after challenge test and a significant increase in antibody titer.
Extracellular vesicles - on the cusp of a new language in the biological sciences
Authors: Raposo Graca , Stahl Philip D.
Published: May 2023

Extracellular vesicles (EVs) play a key role both in physiological balance and homeostasis and in disease processes through their ability to participate in intercellular signaling and communication. An ever-expanding knowledge pool and a myriad of functional properties ascribed to EVs point to a new language of communication in biological systems that has opened a path for the discovery and implementation of novel diagnostic applications. EVs originate in the endosomal network and via non-random shedding from the plasma membrane by mechanisms that allow the packaging of functional cargoes, including proteins, lipids, and genetic materials. Deciphering the molecular mechanisms that govern packaging, secretion and targeted delivery of extracellular vesicle-borne cargo will be required to establish EVs as important signaling entities, especially when ascribing functional properties to a heterogeneous population of vesicles. Several molecular cascades operate within the endosomal network and at the plasma membrane that recognize and segregate cargos as a prelude to vesicle budding and release. EVs are transferred between cells and operate as vehicles in biological fluids within tissues and within the microenvironment where they are responsible for short- and long-range targeted information. In this review, we focus on the remarkable capacity of EVs to establish a dialogue between cells and within tissues, often operating in parallel to the endocrine system, we highlighting selected examples of past and recent studies on the functions of EVs in health and disease.

Shifting focus from the field of distributed and decentralized technologies in the management of intelligent transportation systems (ITS), we now delve into the specific application of blockchain in transportation management. Blockchain is a fundamental component of distributed and decentralized technologies. The research paper discusses the utilization of blockchain technology in managing transportation systems through multi-agent systems. Specifically, the use of blockchain technology is examined in the context of the quick road system (QRS) in ITS to provide a service for obtaining a special fare status. This service aims to establish a decentralized network that facilitates real-time road lane sharing. The study indicates that depending on traffic situations, drivers can share their lane space with other vehicles traveling on the same route by exchanging incentives via blockchain with other private car owners, thereby allowing for faster travel for individuals in a hurry or those requiring priority access to fast lanes. The paper also addresses the increasing number of connected devices in ITS due to the development of the internet of things (IoT) technology. It highlights the importance of efficiently utilizing large datasets and identifies the internet of vehicles (IoV) as a crucial area of integration for existing IoT technologies to address smart traffic within multi-agent systems.

Наведено результати аналізу двомодового резонатора петльового типу зі шлейфом, який перебудовується за частотою двома змінними ємностями. Вперше встановлено, що всупереч існуючому уявленню, такі резонатори мають не тільки двомодові коливання, а й поодинокі коливання, причому ці коливання чергуються між собою. Резонансні частоти цих резонаторів описуються не двома, а трьома рівняннями резонансу: одне рівняння звичайних коливань; два рівняння для парних та непарних мод двомодових коливань. Характерно, що поодинокі коливання є фіксованими і не залежать від змінних ємностей. Діапазонність парної та непарної мод двомодового коливання є різною. Парна мода має ширшу резонансну область і характеризується більш високою діапазонністю. Доведено, що підвищення характеристичного опору шлейфу призводить до розширення діапазону непарної моди, а, отже, і двомодового коливання в цілому. Наведено дані експериментальних вимірювань та моделювання.

В роботі представлені моделі, що дозволяють оцінити вплив первинних параметрів рухомого радара на особливості вторинних сигналів, які виникають у приймачі при обчисленні дальності до рухомої цілі. Це дозволяє змоделювати різні методи обробки сигналів, визначити обмеження цих методів, та сформулювати рекомендації щодо побудови та апаратно-програмних рішень, які доцільно закласти в схему рухомого радара, який відстежує рухому ціль.
Показано, що застосовуючи рівнобічний трикутний закон ЛЧМ з періодом 20 мкс в сигналі зондування з носійною частотою 24 ГГц та девіацією частоти 250 МГц, можливо визначити дальність до рухомої цілі відносно рухомого радара. Відстань між ними визначається однозначно з використанням когерентної обробки прийнятих сигналів. Розглянуто ідеальний випадок розповсюдження сигналів.

The Süttő 21 site is a fissure fill of the freshwater limestone of the Gazda quarry in Süttő. The material was collected between 2017 and 2019, the results are summarised in this article, with a special focus on the small vertebrate fauna of the site and its stratigraphic and paleoecological significance. The fissure fill can be placed around the early/middle Pleistocene boundary (ca. 1.1 and 0.77 Ma). The paleoecological analysis of the herpeto- and mammal fauna of the sequence indicates the proximity of a permanent water body. The lower part of the sequence is dominated by open habitat indicator taxa indicating a cool, dry climate. Towards the upper part of the sequence, the climate remained cool but became wetter, and the vegetation gradually changed to forest-steppe/open forest. The fauna of the Süttő 21 site can be compared with the material of sites, which are of similar age, thus revealing taxonomic and paleoecological differences between different areas of the country. While a warm, dry climate and open vegetation can be reconstructed in the Villány Hills around the early/middle Pleistocene boundary, the northern Hungarian areas had a cooler, wetter climate, and slightly more closed (grove, forest-steppe) vegetation during this period.

To increase the prediction accuracy of positive oral food challenge (OFC) outcome during stepwise slow oral immunotherapy (SS-OIT) in children with hen’s egg (HE) allergy, we evaluated the predictive value of the combination of antigen-specific IgE (sIgE) with antigen binding-avidity and sIgG4 values. Sixty-three children with HE allergy undergoing SS-OIT were subjected to repeated OFC with HE. We measured the ovomucoid (OVM)-sIgE by ImmunoCAP or densely carboxylated protein (DCP) microarray, sIgG4 by DCP microarray, and the binding-avidity of OVM-sIgE defined as the level of 1/ IC50 (nM) measured by competitive binding inhibition assays. The OFC was positive in 37 (59%) patients undergoing SS-OIT. Significant differences in DCP-OVM-sIgE, CAP-OVM-sIgE, I/ IC50, DCP-OVM-sIgG4, the multiplication products of DCP-OVM-sIgE and binding-avidity of DCP-OVM-sIgE (DCP-OVM-sIgE/IC50) and DCP-OVM-sIgE/sIgG4 were compared between the negative and positive groups (p<0.01). Among them, the variable with greatest area under the receiver operating characteristic curve was DCP-OVM-sIgE/IC50 (0.84), followed by DCP-OVM-sIgE/sIgG4 (0.81). DCP-OVM-sIgE/IC50 and DCP-OVM-sIgE/sIgG4 are potentially useful markers for the prediction of positive OFC during HE-SS-OIT and may allow proper evaluation of the current allergic status in the healing process during HE-SS-OIT

Cancer is a catchall term that refers to a collection of more than one chronic disease that can adversely affect the body, including the organs of the body. These diseases can be grouped together under the umbrella term "cancer." Cancer is a catch-all term that is used to refer to a number of different diseases. During the process of looking for new chemical entities, it was found that certain compounds with a basic nucleus of benzoic acid (BA) exhibit a remarkable anticancer potential. This was discovered while the researchers were looking for new chemical entities. In the sixteenth century, the aromatic chemical known as BA, which is also known as an aromatic carboxylic acid, was discovered. BA is also referred to as an aromatic carboxylic acid. When it comes to the chemical synthesis of a wide range of different active molecules, the utilization of a sizeable quantity of BA as a raw material is absolutely necessary. In addition to being present in a variety of other naturally occurring compounds, the BA moiety is the component that is responsible for the activity of the naturally occurring compounds vanillin, gallic acid, and syringic acid. In the synthesis of a wide variety of synthetic bioactive molecules, the BA scaffold is utilized as a building block. The drugs furosemide, bumetanide, benzocaine, tetracaine, and bexarotene are all examples of molecules that fall into this category. The scope of this review article allows for the discussion of a number of noteworthy and recent achievements of BA derivatives in terms of their effectiveness against cancer.
