Published: November 2023

BACKGROUND:Stress urinary incontinence in women is a widespread disease. It can occur in women of reproductive age, while progressing and disrupting the quality of life. Ultrasound elastography allows for evaluating the stiffness of the urethral supporting structures and can help in studying the pathophysiology of stress urinary incontinence and in diagnosing its mild forms for timely initiation of therapy and preventing the development of severe forms of the disease.
AIM:The aim of this study was to improve the diagnosis of mild stress urinary incontinence in women using ultrasound compression elastography of the ureterovesical junction.
MATERIALS AND METHODS:We examined 25 women with mild stress urinary incontinence (main group) and 15 patients without urinary incontinence (control group) of reproductive and perimenopausal age. The diagnosis of stress urinary incontinence was confirmed during a comprehensive urodynamic study. To assess the urethral mobility and determine the stiffness of the supporting structures, a 2D ultrasound examination was performed with compression elastography of the ureterovesical junction using Voluson E6 and E10 ultrasound systems equipped with a transvaginal probe (GE Healthcare, USA). Four areas of interest in the paraurethral region of the proximal and middle urethra were examined. The obtained elastograms were used to evaluate the color characteristics and strain ratio of the areas of interest in three dimensions, the average values being calculated.
RESULTS:The strain ratios in all studied areas of the paraurethral region had no significant relationship with age and were lower in patients with stress urinary incontinence compared to control values (p 0.01). Urethral hypermobility (mobility: mean urethral α angle rotation of 40 degrees) was identified in 84% of women with stress urinary incontinence. According to the results of correlation analysis, the strain ratios in the three areas of interest had a significant negative relationship with changes in the urethral α angle rotation. The ROC analysis showed that the stiffness values of the paraurethral region of the proximal posterior wall of the urethra are the most significant parameters for the diagnosis of stress urinary incontinence. The threshold value of the strain ratio for diagnosing stress urinary incontinence was determined to be less than or equal to 0.85 (sensitivity 96.0%; specificity 86.7%;p 0.001).
CONCLUSIONS:Ultrasound compression elastography of the ureterovesical junction is a new non-invasive technique that can improve the accuracy of diagnosing stress urinary incontinence in women. It is advisable to use the technique in women with mild stress urinary incontinence who are planned for conservative treatment to confirm the diagnosis and monitor therapy.

Published: November 2023

Autoimmune pancreatitis is a specific peculiar and rather new form of chronic pancreatitis (ChP) that has been intensively studied by pancreatology specialists of the whole world for the last years. Autoimmune pancreatitis does not have any individual specific clinical features. This condition was described for the first time in adults and it often mimics pancreas cancer. Autoimmune pancreatitis can involve some organs, synchronously or metachronously, and is rarely identified in children. Autoimmune pancreatitis is a systemic fiber-inflammatory condition with poorly understood pathophysiological mechanism, affecting different parts of the body. In case of the treatment absence the disease can lead to fibrosis and irreversible impairment of the organs. However, the combination of the findings of serologic, histologic, and instrumental methods of investigation characteristic for аutoimmune pancreatitis allows to identify its presence. IgG4-associated disorder has been mainly described in adults, therefore pediatricians usually do not know much about it. We underline the complexity of the diagnosis of autoimmune pancreatitis / IgG4-associated disorder, in children. The article presents two clinical cases of children diagnosed with autoimmune pancreatitis. Both children had the symptoms of abdominal pain and/or mechanical jaundice combined with focal pancreas enlargement, roughness of the basic pancreas duct and distal narrowing. According to our data, the diagnosis of autoimmune pancreatitis in children can be made on the basis of the combination of specific clinical symptoms at admission and various results of imaging. Both timely made diagnosis and administered treatment provide a favorable prognosis for further course of the disease and complication development.

BACKGROUND: Nephrotuberculosis is characterized by the accumulation of extracellular matrix proteins, the regulation of which is carried out by matrix metal propriets (MMP).
AIM: To study the dynamics of the MMP / inhibitors of the blood in the treatment of experimental nephrotuberculosis using mesenchymal stem cells (MSC).
MATERIALS AND METHODS: Among the 20 rabbits with nephrotuberculosis caused by the Mycobacterium tuberculosis, the group 1 compiled by untrue animals; group 2 — with anti-tuberculosis therapy; group 3 — with anti-tuberculosis therapy and mesenchymal stem cells. The development of nephrotuberculosis was confirmed by the reaction with Diaskintest. In the blood serum, the levels of MMP (MMP-1,-9), their tissue inhibitor-TIMP-1, cystatin C (CC), creatinine (KR), albumin (AL), ceruloplasmin (CP), neutrophilic elastasis (NE) and adenosin deaminase (ADA) were determined. A histological examination of the kidneys was carried out. Used Statistica 7.0.
RESULTS: The presence of specific inflammation in the kidneys by 2.5 weeks in all groups was confirmed by increased levels of ADA, CP and a decrease in the body weight of animals, but was not accompanied by changes in the MMP-1,-9, TIMP-1, CC and KR. By the 21st week after infection in all groups, an increased level of ADA, NE and the KR was preserved, and the concentrations of CP and AL were normalized. In group 1 alone, high levels of MMP-9 and CC, foci of specific inflammation and distinct glomerulus changes were noted. The differences between the groups 3 and 2 were associated with lower values of the area of interstitial fibrosis and collagen (p = 0.03). A discriminant function based on the values of the MMP-1,-9, TIMP-1, NE, KR and CC, characterizing significant differences between three groups has been obtained.
CONCLUSIONS: 1. Nephrotuberculosis in rabbits infected with the Mycobacterium tuberculosis 5582 Beijing genotype, after 2.5 weeks was characterized by an increase in the blood of ADA, NE, CP and a decrease in AL, and the lack of changes in the MMP-1,-9 and TIMP-1, KR and CC. 2. The processing of nephrotuberculosis was accompanied by an increase in the blood of concentrations of hell, NE and KR, MMP-9 and CC, but not MMP-1 and TIMP-1. 3. The therapy of the anti-tuberculosis and mesenchymal stem cells normalized the levels of the MMP-9 and the CC, but not ADA and NE. 4. The complex from MMP-1,-9, TIMP-1, NE, KR and CC, allows you to differentiate groups with different vephrotuberculosis activity.
Lysosomal storage diseases. Sphingolipidoses — gangliosidoses

Published: November 2023

Epidemiology, clinical, biochemical and molecular genetic characteristics of gangliosidoses, genetically heterogeneous group of autosomal recessive diseases caused by hereditary deficiency of lysosomal glycohydrolases involved in the catabolism of GM1-, GM2- and GA2-gangliosides, are presented. Three clinical forms of GM1 gangliosidosis are caused by hereditary deficiency of lysosomal β-galactosidase, one of the activities of which is the release of galactose from carbohydrate complexes. As a result, GM1-ganglioside and, to a lesser extent, keratan sulfate accumulate in the lysosomes of neurons and other cells. Three genetically heterogeneous forms of GM2-gangliosidosis are associated with dysfunction of hexosaminidase activity. Tay–Sachs disease, or GM2 ganglioside variant B, is caused by mutations in the hexosaminidase alpha chain HEXA gene. Sandhoff’s disease is associated with mutations in the HEXB gene for the hexosaminidase beta chain. In this case, there is a deficiency of the A and B components of the enzyme — the null variant of GM2 gangliosidosis. In variant AB, or juvenile GM2 gangliosidosis, all hexosaminidase components are present, but the activating factor is defective due to mutations in the GM2A gene. All types of gangliosidosis are characterized by progressive retardation of psychomotor development and early death of patients, most often under the age of 3 years. The frequency of various types of gangliosidoses in different populations does not exceed 1 : 300,000. An exception is the ethic group of Ashkenazi Jews, in which the incidence of Tay–Sachs disease, reaches 1 : 3000, which makes total screening of heterozygotes and prenatal diagnosis of the disease in high-risk families economically justified. The article highlights the importance of experimental models for studying the molecular basis of pathogenesis and developing various therapeutic approaches, such as bone marrow transplantation, enzyme replacement therapy and substrate reducing therapy, gene therapy, and genome editing. Clinical examples of patients with gangliosidosis are given to improve the efficiency of diagnostics of these rare diseases by clinicians.
Pain after hip arthroplasty: personal reflections of an anesthesiologist
Authors: Sitkin Sergey I.
Published: November 2023

Hip arthroplasty is one of the most common surgeries performed globally, with more than 500,000 operations int the US and 3.1 million in Europe performed annually. In 2019, 147,061 hip and knee arthroplasty surgeries were performed in Russia. Hip arthroplasty involves a moderate degree of trauma and is performed under neuraxial anesthesia. However, severe pain in the early postoperative period has been reported postarthroplasty. I had a hip arthroplasty performed under spinal anesthesia with «heavy» bupivacaine (12.5 mg). The operation lasted for 1 hour and motor block regressed 5 hours postsurgery. One hour after the end of the motor block, I experienced mild pain (VAS score 2). The pain intensified to VAS score 7 after 2 hours. Intramuscular injection of 10 mg morphine did not relieve the pain. One hour after morphine administration, 30 mg of ketorolac was administered intramuscularly. After 60 minutes, pain intensity decreased to VAS score 3. Morphine and ketorolac were then administered simultaneously at night and achieved pain levels of VAS score 1–2. The following day, morphine and ketorolac were administered in the morning and evening, resulting in complete pain resolution. No more analgesics were used. In my opinion, the combination of morphine and ketorolac on the day of surgery and twice the next day allows complete elimination of pain after hip arthroplasty.

A Secretaria Municipal de Educação de Belford Roxo (RJ), em 2018, elaborou um projeto interdisciplinar voltado à Educação de Jovens e Adultos configurado com o objetivo de desconstruir paradigmas e dar visibilidade ao sujeito periférico (SPIVAK, 2010; AZIBEIRO, 2012). Para tanto, durante as aulas de Língua Portuguesa e de História em uma escola da cidade, foi analisada a obra Diário de Bitita, de Carolina Maria de Jesus, a fim de fomentar percepções a respeito de uma escrita plural a rearticular formas hegemônicas de conhecimento (MIGNOLO, 2003) e a descolonizar (QUIJANO, 1999) abordagens monotópicas. Como resultado do projeto, os alunos se sentiram estimulados a tecerem suas próprias escritas, tornando-se protagonistas dos seus discursos.
Oswald de Andrade, dramaturgo piromaníaco
Authors: Penteado Flávio Rodrigo
Published: November 2023

O artigo se propõe a examinar a atuação de Oswald de Andrade como dramaturgo, com destaque para A morta – ato lírico em três quadros (1937). A peça se encerra com um incêndio, provocado pela personagem do Poeta e cujas chamas se espalham por todo o teatro. Por um lado, é possível enxergar nesse desfecho a explicitação do furtivo ímpeto revolucionário da obra, na qual se encena o embate entre a classe trabalhadora insuflada por ideias marxistas e a elite patronal adepta do integralismo fascista. Por outro lado, também é possível enxergar nele a contrapartida alegórica do aniquilamento da forma dramática manifesta nesse drama. A análise aqui empreendida busca equacionar ambas as perspectivas de abordagem, tanto ao evocar o contexto sociopolítico subjacente à composição do texto quanto ao realçar aspectos da peça como a separação entre corpo e voz ou o esvaziamento da ação dramática. Por fim, pretende-se assinalar que os atributos estéticos da peça, responsáveis por distanciá-la de convenções teatrais em vigor na época de sua escrita, contribuem, hoje em dia, para que sua leitura seja muito estimulante no início do século XXI.

Traditionally, medical education comprises both theoretical learning in classrooms and clinical training in hospitals where students can gain clinical experience. This is mostly done on face-to-face teaching models, focused on the educational philosophy of “see one, do one, teach one”, was the standard teaching methodology in medical education. Medical education is transforming thanks to medical schools adopting innovations to new clinicians, such as immersive prepare techniques (extended reality): virtual reality, augmented reality and virtual reality. Immersive learning technologies, such as extended reality, can provide an engaging and interactive platform to generate a stimulating learning environment and with the recent development and increased accessibility of immersive technologies, educators have the potential to make simulation-based training more effective. By using holographic devices, such as Microsoft HoloLens 2®, and 5G wireless communicationswe intent to explore the innovative experience of a robot-assisted orthopaedic surgery, where the procedures were transmitted live stream to Pregraduate Medical Students using the Microsoft Remote Assist®. In addition, students had the opportunity to interact directly from a classroom to the operating room, asking to the surgeon about the procedures performed during surgery and get involved in the surgery, even remotely. At the end, students completed a questionnaire to evaluate the experience and the preliminary results made possible to assess the effectiveness of this experience and identify areas for improvement for future surgery transmission, revolutionizing the teaching and practice of surgery
Hardening of a Continuous Behavior-based Authentication Distributed System

Published: November 2023

"Password-based traditional authentication systems are increasingly insufficient when it comes to providing security and checking the identity of the authenticated user. What happens when the password of an user has been stolen or an active user is not the same user who authenticated firstly? A distributed system using AI (Artificial Intelligence) acting as a second factor authentication method by analyzing user's mouse events has to provide confidentiality and integrity in order to protect against different attacks such as Man-In-The-Middle that allow sniffing or data tampering, resulting in an identity spoof. In order to grant integrity and confidentiality, encryption and authentication must be implemented. Authentication is used to allow one node to produce or consume data from an existent message stream and encryption in order to avoid exposing these data to external agents. PKI (Public Key Infrastructure) system is widely used over the internet, so it is a trusty authentication and encryption framework. By using PKI in this project, hardening is performed by creating with OpenSSL a trusted Certificate Authority that issues and signs the certificates used by each node in the distributed system. Trust in this Certificate Authority is implemented by creating keystores and truststores for each node with keytool. This project resulted in a secure communication system preventing data from being sniffed or tampered."
Uncertainty Reduction Strategies on Share in Jar Skincare’s Purchase Intention
Authors: Argyanti Talitha , Destrity Nia Ashton
Published: November 2023

Share-in-jar skincare products come up with a relatively high level of uncertainty as sales are commonly only made online, thus making it impossible for consumers to ascertain the product’s quality and suitability. Indonesians, on the other hand, are said to have a low uncertainty avoidance, which tends to be more tolerant of uncertainty and is supposed to be less active in seeking information to reduce uncertainty. This study aims to analyse the effect of uncertainty reduction strategies on the purchase intention of share-in-jar skincare products on marketplaces and social networking sites (SNS) in Indonesia. This study used an explanatory quantitative approach with a survey method. It involved 395 Indonesian consumers who had searched for information about share-in-jar skincare products through marketplaces or SNS. The multiple linear regression analysis revealed that Indonesian consumers had a low level of uncertainty avoidance but actively sought information before purchasing products. The passive, active, and interactive strategies simultaneously affected the intention to buy share-in-jar skincare products, but the active strategy had no effect when tested partially. The passive strategy was the most influential uncertainty reduction strategy toward the purchase intention of share-in-jar skincare products.

Methicillin resistant s (MRSA) screening is a routine practice at many hospitals for high-risk patients. However, its incidence and clinical significance in expectant mothers are poorly understood. Hence, the purpose of the current study was to look at MRSA colonization rates in our obstetric population.

Prospective study was conducted for three months from December 2019 to February 2020. MRSA screening samples from pregnant women at 32-34 weeks of gestation were collected after informed consent. All screening samples underwent standard microbiological analysis. Women who tested positive for MRSA received a decolonization program and their care was monitored.

Total 78 mothers were included in the study. The rate of MRSA colonisation was 2.5% at 32 – 34 week of gestation. Decolonization protocol was advised for MRSA carriers.

Our obstetric population has a low colonization rate for MRSA. Infections could be decreased with targeted antenatal MRSA screening and decolonization in women at high risk. Continued monitoring of MRSA infections in obstetric population and their infants is required.

Published: November 2023

Aunque no todos los jóvenes van a poder lograr el trabajo que desean, sus aspiraciones tienen consecuencias en sus trayectorias educativas y laborales. Cuantifcar cuán alcanzables son las aspiraciones de los jóvenes es clave para diseñar políticas efectivas. Este trabajo se propuso explorar qué aspiraciones educativas y laborales tienen los y las jóvenes en Uruguay para luego cuantifcar qué brechas existen entre esas aspiraciones y la realidad de lo que el mercado laboral puede ofrecerles. Para ello se realizó una encuesta a más de mil jóvenes uruguayos de entre 18 y 24 años y también grupos focales. A pesar de las difcultades que enfrentan en el presente, la mayoría de los jóvenes son optimistas en cuanto al empleo que esperan alcanzar lo que genera una brecha entre las aspiraciones y las oportunidades que brinda el mercado laboral. A su vez, las aspiraciones laborales de los jóvenes se encuentran concentradas en un limitado número de ocupaciones y existen diferencias por género y nivel socioeconómico. La mayoría de los jóvenes que están empleados no están satisfechos con sus empleos y ven poca vinculación entre sus empleos y sus estudios. De estos hallazgos se desprende que existen ganancias potenciales para Uruguay de una mayor alineación entre las aspiraciones de los jóvenes y las oportunidades del mercado laboral. El trabajo cierra con una serie de propuestas de políticas públicas orientadas a asegurar trayectorias educativas, proveer información y orientación a los jóvenes, reducir el desajuste de habilidades y promover el acceso a un primer empleo de calidad.

Los diferentes componentes de las cenizas volcánicas no tienen igual susceptibilidad a meteorizarse, ello es evidente por los resultados obtenidos en esta investigación. Se tomaron fragmentos de matriz (FM), vidrios volcánicos coloreados (VVC) y vidrios volcánicos incoloros (VVI) y se sometieron a disolución durante 625 días en ácido húmico (AH), en agua acidulada (AA) y en ácido oxálico (AO). Se observó que los FM presentan mayor superficie específica, mayor superficie de reacción, mayor número de rasgos de alteración superficial y producen mayores cantidades de iones de Al3+, Si4+ y Fe3+, por ende, son los más susceptibles de ser meteorizados, siguen a estos los VVC y luego los VVI. Durante la experimentación (625 días), la mayor disolución se produce a un rango de pH entre 6.0-7.2; de los tres reactivos, el AH es el que más disuelve a los materiales seguido por el AA o el AO que se comportan de manera diferente, durante el primer y tercer ciclo la relación es: AH>AA>AO, en el segundo ciclo la relación es: AH>>AO>AA.

La mayoría de los valores experimentales obtenidos de la disolución se ubican dentro del campo de estabilidad de la imogolita. Al disminuir la actividad del H4SiO4 y el pH, se posibilita en algunos casos, la formación de gibsita y el sistema se acidifica. Cuando disminuye la actividad del H4SiO4 y aumenta la del Al3+, unos pocos valores se mueven hacia los valores teóricos de la actividad de la haloisita. A medida que aumenta la actividad del H4SiO4 y disminuye la del Al3+ los valores se acercan hacia los valores teóricos de la actividad de la imogolita, mineral que presenta la menor relación de actividades, es el más estable, el que menos se disuelve y presenta menor energía libre. Los diversos reactivos tienen un efecto particular sobre las velocidades de disolución de los FM, los VVC y los VVI y en la producción de los iones Al3+, Si4+ y Fe3+. En los tres ciclos, los FM liberan iones de Al3+ y Si4+ a una velocidad mayor que la de los VVC y la velocidad de éste es mayor que la de los VVI. Las velocidades para liberar Fe3+ son más altas en los VVI y en los VVC que en los FM.

Imiquimod-induced psoriasis model: induction protocols, model characterization and factors adversely affecting the model
Authors: Alsabbagh Manahel Mahmood
Published: November 2023

Imiquimod-induced psoriasis is widely-employed to study disease pathogenesis and to screen drugs. While the original protocol was published more than a decade ago and has been rigorously used in research since then, a modified protocol was described recently with several advantages including milder systemic manifestations although the disease morphology is highly conserved. Being a toll-like receptor 7 and 8 agonist, IL-23/IL-17 axis predominates in imiquimod-induced psoriasis. In addition, different immunocytes were described to aggravate or supress the disease. This article aims to review the currently available protocols of imiquimod-induced psoriasis in vivo, to characterize the model as described in literature and to define the five important independent factors adversely influencing the model which researchers should pay attention to.

El crecimiento de la gig economy en los últimos años ha revolucionado el mundo laboral por los cambios que se han generado en la organización, formas de control y estructura del mercado laboral en un contexto cada vez más flexible y tecnológico; sin embargo, a esto se acompañan características propias de la precariedad laboral. En este contexto, el artículo busca responder cómo los trabajadores de la gig economy se adaptan y reaccionan a las formas de control y poder ejercidos por las plataformas. Con base en la experiencia de repartidores de la plataforma Rappi en Lima Metropolitana a partir de un estudio de caso, esta ianvestigación incide en dos puntos importantes: por un lado, se analizan las estrategias de control utilizadas por la empresa sobre sus trabajadores, aprovechando la crisis generada por la COVID-19 y, por otro lado, la situación migratoria que caracteriza a la mayor parte de esta fuerza laboral. Así, se identifican cuatro formas de control: el sistema de evaluación del cliente, el discurso de flexibilidad, la asimetría de información y las recompensas e incentivos. Por otro lado, se indaga en las tácticas y mecanismos empleados por los repartidores como respuesta para realizar, eludir y resistir frente a la degradación de las condiciones de trabajo. Este artículo ofrece una doble contribución: en primer lugar, aborda un tema poco estudiado en un contexto particular como el peruano, cuyo mercado laboral se caracteriza por ser altamente informal y precario; y, en segundo lugar, constituye un avance en la investigación sobre las relaciones de control y resistencia en la gig economy.
Tu príncipe azul es un agresor: la idealización del amor romántico y su influencia en la violencia de género dentro del contexto latinoamericano
Authors: Guevara Bustamente Andrea
Published: November 2023

El amor romántico constituye un repertorio de creencias sobre el ideal del amor, ideas que construyen imaginarios sobre lo que se espera de las relaciones de pareja, así como sobre los comportamientos considerados adecuados para las mujeres y los hombres en el ámbito sexo-afectivo. La violencia contra las mujeres es un crimen recurrente en Latinoamérica, esta se perpetúa constantemente dentro de la esfera íntima de las víctimas, sobre todo es ejercida por sus parejas o exparejas. Teniendo en cuenta la vigencia de ambos fenómenos, la presente investigación analizó la influencia de la idealización del amor romántico en la violencia de género dentro de parejas de adolescentes y jóvenes heterosexuales de Latinoamérica mediante una revisión bibliográfica. En ese sentido, se planteó como objetivo analizar la contextualización y el impacto de esta corriente en la violencia de género, para lo cual se explica el concepto del amor romántico y el significado de la violencia de género. Además, el trabajo en cuestión mostró cómo la idealización de esta teoría del amor occidental ha normalizado, facilitado y erotizado la violencia de género dentro de las parejas, en específico entre los jóvenes y adolescentes de América Latina. En primera instancia, se explicó la justificación de conductas socioemocionales nocivas, como la dependencia emocional y la decisión de priorizar la pareja, a partir de esta construcción sociohistórica del amor. En segundo lugar, se analizó la manera en que este ideal fortalece los roles de género. De esa forma, se concluyó que el amor romántico facilita la violencia, romantizando actitudes agresivas y los estereotipos de género.

Indonesia's education system has been facing a significant learning crisis, as evidenced by the country's declining scores in the 2018 PISA results and its expected drop in the English Proficiency Index ranking in 2022. To tackle this challenge, Indonesia has introduced an Emancipated Curriculum that aims to transform learning in the country. The Emancipated Curriculum is designed to be student-centered, differentiated learning, project-based learning, exploratory learning, and holistic learning. This study discusses the discussion of the Kurikulum Merdeka, school perceptions about the meaning of the Independent Curriculum, implementation in secondary schools. This research uses qualitative research with a case study method. The data in this research was obtained from interviews and documents.  The findings show that teachers plan the curriculum with a focus on critical and creative thinking, develop their own learning materials to enhance students' cognitive abilities, and make changes to syllabi and lesson plans. However, the study also reveals that the learning media being developed is not yet digital, which may hinder the effective implementation of the Emancipated Curriculum. Furthermore, traditional learning approaches still dominate the assessment and learning processes. Overall, this study sheds light on the development of the Emancipated Curriculum and highlights the need for further research in this area.

Cette étude avait pour but d’évaluer la dynamique saisonnière des pâturages herbacés dans la zone sahélienne du Burkina Faso. Pour estimer la biomasse de la strate herbacée, deux opérations de coupe de la biomasse espacées d’un intervalle de quinze jours ont été effectuées chaque mois dans dix parcelles permanentes de 100 m2 ainsi que des relevés phytosociologiques afin de distinguer les différents types de pâturages. L’évolution de la biomasse en fonction du temps a montré des phases distinctes. La première phase (juin – juillet) avec une croissance lente constitue la phase d’installation de la végétation dont les conditions d’humidité sont favorisées par les premières pluies. La deuxième phase qui s’étale d’août à septembre où la production est culminante constitue la phase de maturation des herbacées. Le pic de la production dans chacun des pâturages est observé durant cette période où la réserve utile des sols est élevée. La quatrième phase (octobre – novembre) traduit la décroissance de la production de la strate herbacée. La vitesse de croissance journalière de la biomasse de la strate herbacée est irrégulière. La croissance de la strate herbacée commence tout juste après les premières pluies. Les valeurs élevées (de 7 à 19,0 g.jour-1) se situent au cours des mois de juillet jusqu’au début du mois de septembre, ce qui correspond aux mois où la réserve utile du sol est maximale. La production de biomasse varie en fonction des pâturages. Le pâturage à Piliostigma reticulatum et Justicia insularis est le plus productif avec 0,91 ± 0,97 tonnes de matières sèches par hectare. Les capacités de charge ont varié de 0,0 à 0,7 UBT.ha-1 par mois et interpellent sur la nécessité de modérer la pâture et d’enrichir les parcours sahéliens.

Cattle farmers are developing adaptation strategies to deal with the effects of climate change. Understanding how adaptation affects livestock productivity is, therefore, essential in order to identify and prioritize the optimal strategies. Yet, few studies have addressed this issue. This study aims to fill the gap, by assessing how the adaptation strategies developed by cattle farmers in Benin affect livestock productivity. We conducted surveys with 360 cattle farmers and monitored 30 farms in Benin’s dry and sub humid tropical zones. We collected data on the socio demographic characteristics of cattle farmers, their adaptation strategies and herd productivity. We carried out a multiple correspondence analysis, followed by an ascending hierarchical classification to establish the typology of the cattle farmers’ adaptation strategies. We tested data on livestock productivity using an analysis of variance with the generalized linear model procedure of R.3.5.1. software. The results revealed three groups of adaptation strategies: integrating livestock with crop production; use of supplemental feeding and fodder crops; pastoral mobility. The choice of strategy significantly affected livestock productivity. Animal mortality rates were lower on farms that adopted supplemental feeding (2.7%), and integrated crop/livestock systems (3.3%), compared to farms with pastoral mobility (5.2%). Supplementary feeding improved calf weights at birth and at 6 months and increased daily milk offtake. Based on the results obtained, we recommend that farmers adopt supplemental feeding and integrated crop/livestock strategies in the study zones to improve herd productivity.

The flow of information technology development cannot be contained. Migration from the era of citizens to netizens is an impossible thing to avoid. This study aims to examine the relationship between the development of information technology in the digital era, especially on social media, and the Human Rights perspective. This research uses normative legal research methods to find ideal formulations and boundaries for netizens to become polite people interacting on social media. The results of this study show that Indonesian's right to an opinion on social media is a constitutional right that has been regulated in the 1945 NRI Constitution and the UDHR. However, freedom of speech does not mean that there are no limits. The limitations of freedom of speech on social media are through the limitations of norms, especially norms of politeness and decency, whose values are universal.

Published: November 2023

The spread of fake news on social media raises many legal problems in Indonesia. These legal problems are mainly seen in the formulation of the law as well as in the law enforcement area. Legal problems related to the spread of fake news must be resolved at the level of legislation, policy, and law enforcement because it negatively impacts someone. In addition, studies on the spread of fake news in the Indonesian context are still overlooked. Therefore, reviewing the regulation on criminal liability for those who spread fake news on social media in Indonesia is very important. The doctrinal legal research methodology investigated three main issues discussed in this article. First, the current study shows that the act of spreading fake news on social media cannot be charged with Article 28 of the Indonesia Law Number 19 of 2016 concerning amendments to Law Number 8 of 2011 concerning Information and Electronic Transactions. Second, from several Indonesian court decisions studied, judges in deciding cases of spreading fake news on social media applied Law Number I of 1946 concerning Criminal Law. Lastly, related to criminal law reform, spreading fake news on social media should also be regulated by the Information and Electronic Transactions Laws.
