Sounds from Below - Protest in Times of Authoritarianism and the COVID-19 Pandemic
Authors: Özden Firat Begüm
Published: May 2024

Begüm Özden Firat approaches authoritarianism and resistance through the lens of the age-old battle between silence and noise. While all political regimes regulate socio-cultural soundscapes, authoritarian regimes might have specific and intricate ways of controlling the auditory and other sensory aspects of public life. This contribution shows how, during the COVID-19 pandemic, new strategies of auditory resistance against the neoliberal authoritarian AKP regime emerged in Turkey.
Songs for Free Syria and Regional Cross-Border Solidarity
Authors: Ayoub Joey
Published: May 2024

Joey Ayoub's contribution explores the songs of the 2011 Syrian revolution, that was crushed by Assad, survived and are sung today in movements of resistance all over the Middle East and Northern Africa, from Palestine to Sudan and Algeria. It argues that chants, alongside visual creations such as protest signs, memes, music videos, and so on, are important tools of non-violent resistance, especially during times when taking to the streets becomes too dangerous. Often they are more lasting than the political movements they emerge from, reappearing in new forms adapted for the local context, and inspiring new moments of resistance.
Reise ins bekannte Fremde
Authors: Sammeck Marina
Published: May 2024

Japanische Holzschnitte (ukiyo-e) zählen heute zu den berühmtesten Kunstformen Ostasiens. Doch wie haben die Drucke aus der Edo-Zeit diesen Status erhalten? Als Ursprung für ihren Weltruhm wird häufig auf die Japonismus-Epoche Ende des 19. Jahrhunderts verwiesen. Dabei blenden Kunstwissenschaft und Museumswelt aus, dass die Drucke in den letzten siebzig Jahren vielfach präsentiert wurden. Marina Sammeck verfolgt, wie japanische Holzschnitte durch Ausstellungen und Allianzen zu einer der populärsten japanischen Kunstformen im Westen aufsteigen konnten. Im Mittelpunkt ihrer Analyse steht die Beschreibung des Prozesses, in dem spezifische Objekte zu »Kunst« werden - und was dieser für die zukünftige Ausstellungspraxis bedeutet.
Umweltgerechtigkeit
Authors: Böhme Christa
Published: May 2024

Christa Böhme beantwortet in dem Interview Fragen rund um das Thema Umweltgerechtigkeit: Was genau ist unter dem Begriff zu verstehen? Wie wird Umweltungerechtigkeit sichtbar und bei welchen städtischen Gruppen? Wer sind die zentralen Akteure, wenn es darum geht, mehr Umweltgerechtigkeit zu schaffen? Welche Rolle kommt den benachteiligten Bevölkerungsteilen Quartiersbewohner*innen selbst zu? Über welche Qualitäten müssen Orte bzw. Räume verfügen, um einen nachhaltigen Beitrag zu Umweltgerechtigkeit leisten zu können? Welche Rolle spielen Gemeinschaftsgärten bei der Herstellung von mehr Umweltgerechtigkeit? Wie unterscheidet sich der Ansatz "Gesunde Stadt" von dem Ansatz "Umweltgerechtigkeit"?
Merzkunst zwischen System und Chaos
Authors: Wulff Antje
Published: May 2024

Die Merzkunst von Kurt Schwitters gründet auf einem Widerspruch: Sie erscheint als geschlossenes, hochgradig strukturiertes Ganzes, offenbart aber zugleich eine Dynamik, welche die Grenzen zwischen den Künsten sowie zwischen Kunst und Nichtkunst übertritt. Diesen zuvor nie systematisch aufgelösten Gegensatz nimmt Antje Wulff auf Basis der transdisziplinären Systemtheorie in den Blick. Ihre Analyse fokussiert auf das komplexe Wechselspiel von Formbildung und Formauflösung in der Merzkunst sowie ihrer Rezeption. Damit leistet sie eine Neuperspektivierung, die das enorme Erkenntnispotenzial von Merz ebenso belegt wie die Fruchtbarkeit der Systemtheorie für die Geisteswissenschaften.
Gender, Literatur und Film
Authors: Eliseeva Aleksandra
Published: May 2024

Wie interagieren Gender, Literatur und Film in literarischen Verfilmungen? Aleksandra Eliseeva widmet sich den Darstellungen von Gender in Rainer Werner Fassbinders Literaturadaptionen und fokussiert auf den komplexen Zusammenhang mehrerer Filme zu ihren Vorlagen. Auf den Spuren der Passionen des Regisseurs konfiguriert sie ein Makrowerk aus den Texten von Fontane, Döblin, Graf, Fleißer und Kroetz, das sie von den Filmen perspektiviert liest und welches sowohl inter- als auch intratextuelle Bezüge aufweist. Durch den polyperspektivischen, intermedialen Zugriff werden so die latenten Strukturen und persönlichen Lesarten der verfilmten Texte sichtbar.
Im Schatten des Schweigens
Authors: Warnsholdt Lotte
Published: May 2024

Das Geheime ist ein Ort mannigfaltiger Beziehungen. An diesem Ort begegnen sich nicht nur Menschen, sondern zeigen sich auch ihre Verstrickungen in Macht-, Begehrens- und Wissensfelder. Lotte Warnsholdt legt einen Schwerpunkt auf die sozialen und historischen Effekte des Geheimen und adressiert die ambivalenten Wirkungsverhältnisse von Emanzipation und Ausgrenzung. Dazu bedient sie sich bei Theoretiker*innen wie Koselleck, Kittler, Horkheimer oder Hartman. Mit einem Fokus auf die Kulturtechniken des Schweigens und Zum-Schweigen-Bringens eröffnet sich so die Spannweite einer Semantik des Geheimen - und das Verhältnis von moderner Theoriegeschichte zur Verletzlichkeit moderner Subjekte.
Fear and Hoarding in Las Coronas. Krisenvorbereitung der Prepper-Szene in Zeiten der Covid-19-Pandemie
Authors: Mack Konstantin
Published: May 2024

Konstantin Mack widmet sich in diesem Beitrag mit Prepper*innen, deren Praktiken der privaten Vorratshaltung mit dem Beginn der Corona-Pandemie einen regelrechten Aufschwung erlebten. Mit digital-ethnographischen Methoden kann deutlich gemacht werden, wie sich die Prepping-Community einerseits durch die Pandemie bestätigt fühlt und andererseits mit ihren Narrativen von Individualität und Eigenverantwortung schon seit Jahren anschlussfähig sowohl an neoliberale Entwicklungen wie auch an rechtspopulistische und verschwörungsideologische Vorstellungen ist.

Pandemien in der Popkultur. Distanz und Nähe der Pandemieerfahrung
Authors: Görgen Arno , Pfister Eugen
Published: May 2024

In unserer Analyse positionieren wir die gesellschaftliche Wahrnehmung und Konstruktion von Pandemien durch Popkultur in der Systemtheorie, in Theorien der Krisenkommunikation und des sozialen/popkulturellen Gedächtnisses. Als Erstes werden wir eine phänomenologische Einordnung von Prä-Corona-Pandemieerzählungen vornehmen (Kap. 2-6). Als zweiten Schritt legen wir dar, wie sich - zumindest während des Verlaufs der Covid-19-Pandemie - der mediale Erzähltopos (und modus) der Pandemie verändert hat (Kap. 7 und 8). Als Quelle hierfür dienen uns Filme, digitale Spiele, Comics sowie soziale Medien als Rezeptions- und Verarbeitungsmedien von Wissenstransfer durch Popkultur. In die Analyse fließen dabei gleichermaßen Beobachtungen aus eigenen langjährigen Forschungen zu Krankheit in der Populärkultur, etwa zur Medikalisierung in digitalen Spielen, wie auch (Teil-)Ergebnisse der Forschung der Autor:innen dieses Sammelbandes sowie des SNF-Projekts »Horror - Game - Politics« an der Hochschule der Künste Bern ein. Die analyseleitende Hypothese ist, dass im Laufe der Covid-Pandemie ein Wandel sowohl in der Darstellung wie auch in der Perzeption von Pandemien stattgefunden hat: Je näher das reale Katastrophenereignis an die alltägliche Wahrnehmung von Produzent:innen und Rezipient:innen gleichermaßen rückte, um so direkter wurden in ihren Texten Bezüge zur aktuellen Pandemie gesetzt und gezogen.

Arbeit an der Wörtlichkeit
Authors: Körte Mona
Published: May 2024

Das Verlesen ist ein zeitlich-situativer Vorgang, durch den der Fluss des Lesens eine eigene Wendung nimmt und die Bedeutung in eine andere Bahn gelenkt wird. Deutlicher noch als im Versprecher oder Verhörer wird der buchstäbliche Wortlaut auf produktive Weise gestört und verschafft so Einblicke in Strukturen, Verarbeitungsvorgänge und Relationen, die sonst unbeachtet blieben. Eingedenk der Tatsache, dass Lesen durch das fortwährende Vor- und Zurückwandern des aufnehmenden Auges kognitionspsychologisch betrachtet selbst schon ein Abgleichen, Ermitteln und Rückversichern ist, wird in dem Beitrag für die Methode des vergleichenden Lesens argumentiert, nicht um Verleser als zu korrigierende Irrläufer zu klassifizieren, sondern um sie als unvorhersehbare Eigenleistung und seismographische Denkreaktionen zu begreifen. Damit steht vergleichendes Lesen nicht einfach nur im Dienst der Korrektur des Verlesers, sondern streicht das kreative Potenzial von Abweichungen hervor und eröffnet die Möglichkeit, die meist getrennten Bereiche von Lesen und Schreiben als verschränkte, einander überlagernde und einander bedingende zu beobachten.
Transient global amnesia
Authors: Kulesh A. A. , Demin D. A. , Kayleva N. A. , Mekhryakov S. A. , Krapivin S. V.
Published: May 2024

Transient global amnesia (TGA) is a benign, stress-induced neurological syndrome associated with reversible hippocampal dysfunction that manifests as isolated, predominantly anterograde amnesia. Since it is impossible to make a definitive diagnosis of TGA when the patient is admitted to hospital, the primary condition should be interpreted as an acute cerebrovascular accident, which implies a mandatory neuroimaging examination and clarification of the question of thrombolysis according to general principles. When taking a medical history, attention should be paid to the presence of predisposing conditions and triggers: migraine, chronic and acute stress, physical activity, sudden changes in temperature, Valsalva maneuver, coitus, medical procedures. If amnesia does not resolve within 24 hours, a differential diagnosis with stroke, Wernicke–Korsakoff encephalopathy, limbic encephalitis, intoxication and psychogenic (dissociative) amnesia is required. If the symptoms resolve within 24 hours and the classic diagnostic criteria are met, magnetic resonance imaging of the brain in diffusion-weighted mode is performed on days 2 to 4 in order to detect pinpoint zones of diffusion restriction in the hippocampus. If these lesions are visible and a typical medical history is available, the diagnosis of TGA can be made; if no lesions are present, the diagnosis is probable. In the absence of lesions and an atypical history of TGA, differentiation from transient epileptic or dissociative amnesia and transient ischemic attack is required.

Published: May 2024

The high prevalence of primary affective disorders in patients with epilepsy is beyond doubt. However, patients in this group are often identified as suffering from mood disorders that do not fulfil the criteria for primary mood disorders, such as recurrent depressive disorder and bipolar affective disorder. The aim of this paper is to analyze the classification and clinical picture of affective disorders in patients with epilepsy and differential diagnostic approaches to identify primary affective disorders and secondary affective disorders in epilepsy. A set of diagnostic signs for the differential assessment of affective disorders in patients with epilepsy is presented. Research of affective pathology in patients with epilepsy and the development of strategies for its successful treatment are still needed.
Fostering Inclusion Around Housing Transitions
Authors: Annesley Allison , Dever Maddy
Published: May 2024

This qualitative research project was designed to determine how Community Connectors can best support neurodiverse residents when they move into new housing. The research team also sought to generate greater awareness of the Connector role and support for a pilot. Team members collected and analyzed a range of perspectives, including lived experience, by running focus groups, conducting key informant interviews, and consulting with a diverse advisory panel. A Community Connector assisting neurodiverse residents as they transition to more independent housing can have an outsized impact, on housing success, housing stability, and quality of life. The Social Finance for Social Inclusion Solutions Lab has developed an outcomes-based pilot model to increase access to Community Connectors. Connectors help residents form relationships and over time, develop a new network of support. Housing providers may also be more willing to welcome these tenants, knowing they have adequate support. Connectors can also facilitate volunteer or employment opportunities, further integrating residents as full and valued members of the community. We found a social impact bond could be a novel way of increasing access to Community Connectors. Both impact investors and government funders are interested in the outcomes a pilot would likely achieve. Social impact bonds are just one idea though. Any funding model that could pay for an outcomes-based pilot with independent evaluation, would generate the evidence required to scale and increase access to this important resource.
Data Back
Authors: Ellenwood Cheryl , Foxworth Raymond
Published: May 2024

Grounded within the field and practice of philanthropy, the authors discuss the relationship between Indigenous material culture and philanthropy. This tangled relationship between philanthropy, colonial institutions, and Indigenous material culture continues to cause harm for Indigenous Peoples. We illustrate the problematizing nature of museums viewing material culture detached from current Indigenous Peoples with the case of the Nez Perce Wetxuuwíitin Collection. The Nez Perce Wetxuuwíitin Collection case shows how elite philanthropy and museum practices can negatively harm Native nations. Native collections are living Indigenous data and connected to Indigenous Peoples today. Material culture is not relegated to the past; it is Indigenous data and should be governed by Native nations. Without a change in practice, Indigenous Peoples will continue to be negatively impacted. To educate elite philanthropic partners and improve museum practices, we introduce principles from Indigenous Data Sovereignty that can help guide the partnerships and collaborations with Native nations. Indigenous Data Sovereignty can not only reduce harm and maximize benefits for Indigenous Peoples but also bring Indigenous data back home.

The benefits of sustainable functioning are among the most important characteristics of any socio-economic structure. It predetermines the rationality of the formation of results at normalized costs. But sustainability is of particular importance to systems that predetermine the optimization of the state of other participants in market relations. In this aspect, the activities of maritime transport are particularly highlighted, ensuring the rationality of the international division of labor. All subsystems that form cargo flows are interested in the sustainable operation of maritime transport, which provides up to 80 percent of foreign trade. However, the periodic instability of the world merchant fleet is determined by three aspects: the cyclical nature of the world economy, the competitive situation within the global maritime trade market and alternative approaches of opposing economic strategies. Therefore, to achieve transport security and sustainable positioning of national or union economies, it is important to monitor and recognize unwanted crisis situations. In accordance with the characteristics of external influences, response strategies are selected to meet the requirements of ensuring sustainability. Therefore, a specific approach to ensuring risk management is being formed.

General Remarks Before the Mathematical Description Active Basic Models of Economic Dynamics
Authors:   Odesa Polytechnic National University, Semenov Anatoly , Sokolovska Zoia ,   Odesa Polytechnic National University, Budoratska Tetiana ,   Odesa Polytechnic National University
Published: May 2024

The article is devoted to the mathematical basis of research on the dynamics of economic processes at the macro level. The necessity of forming new approaches and adapting existing methods and models to the trends of the modern economy is asserted. An analysis of the basic models of economic dynamics has been carried out. It is proved that from the mathematical formulation of classical models of economic dynamics, for example, the Solow model, exponential growth of the economy follows. The results that follow from the formulation of models concern, in particular, the problem of crisis forecasting. A modification of the mathematical formulation of some well-known models of economic dynamics has been proposed in order to eliminate the inadequate exponential growth of the economy and to bring the results of modeling closer to the dynamics of real processes.

Methods of planning and management in the maritime transport system require a reflection of the peculiarities of the activities of subsystems of the maritime transport industry. In this regard, planning of investment activities should be considered as a guarantee of maintaining or expanding the company's position in the global trade market. An important aspect in the development of maritime transport enterprises is the establishment of effective partnerships with other companies and the development of intermodal transportation systems. This requires the introduction of innovative technologies that increase the efficiency of logistics processes and reduce the time and cost of cargo transportation. The creation of strategic alliances between companies is also important for building competitive advantages and expanding the geographical coverage of cargo transportation.
Paper drinking straws coated with cellulose acetate and polyhydroxyalkanoates via an entropy-driven approach and natural colorants as alternatives for plastic drinking straws
Authors: Zhang Jinlong , Pal Lokendra
Published: May 2024

As a way to reduce microplastics or nano-plastics in the ocean, it is of interest to develop biodegradable paper-based drinking straws to replace non-degradable plastic drinking straws. Primary questions to be addressed include how to design suitable coatings for paper drinking straws. Such coatings not only need to resist water. In addition, consumers have high expectations for the strength of a drinking straw. It is proposed here to replace non-biodegradable polypropylene, which is presently the main component of straws, with biodegradable and hydrophobic coating components via an entropy-driven approach. It is further proposed to develop colored paper-based drinking straws with cellulose nematic liquid crystal photonic pigments as a way to make the product stand out visibly, while at the same time mediating the usage of toxic chemical pigments.
Visit duration of office-based ophthalmology visits in a nationally representative sample
Authors: DeBroff Brian M , Andoh Joana E
Published: May 2024

Purpose: To assess the mean visit duration of office-based ophthalmology visits in the United States. Methods: The National Ambulatory Medical Care Survey (NAMCS) was queried to identify visits conducted by ophthalmologists between years 2006-2016. Primary outcome measure was the time spent with the ophthalmologist (in minutes). Demographic and health information including patient age, sex, race/ethnicity, insurance type, and number of chronic conditions were assessed. Reason for visit, new patient status, number of medications prescribed, electronic medical record use, regional location, and metropolitan status of each visit were also collected. International Classification of Diseases Clinical Modification Ninth and Tenth Revision codes (ICD-9-CM and ICD-10-CM) were used to categorize each visit by subspecialty of primary diagnosis (i.e. cataract, cornea/refractive, glaucoma, oculoplastic, perioperative, and retina). Univariate and multivariate ordinary least square linear regression analyses were used to determine predictors of visit duration. Results: Between 2006-2016, there was an annual average of 52 million ophthalmology office-based visits. Mean visit duration [standard error] was 20.7 [0.4] minutes, annually. An increase in visit duration was observed with a mean of 19.1 [1.5] minutes in 2006 and a mean of 22.5 [1.2] minutes in 2016. The five strongest predictors of visit duration were Medicaid insurance (ß [regression coefficient] 5.1; 95% CI [confidence interval] 1.39-8.74), new patient status (ß 2.7; 95% CI 1.55-3.79), new medications (ß 1.1; 95% CI 0.32-1.92), year of visit (ß 0.7; 95% CI 0.48-0.93), and non-metropolitan location (ß -2.8; 95% CI -4.45- (-1.20)) (all p<0.01). Conclusion: Across 11 years, mean visit duration of office-based ophthalmology visits has increased. Predictors of visit duration reflect healthcare utilization patterns in low-resource populations, provider-patient encounters, a growing aging population, and a shortage of ophthalmologists in rural areas. As interventions are made to better model and improve the clinic experience of ophthalmic patients, these factors should be considered.
Development of a 2g butterfly-style flapping-wing micro aerial vehicle
Authors: Fujikawa Taro , Teranishi Yuki
Published: May 2024

A flapping-wing micro aerial vehicle (FMAV) modeled after a butterfly was developed to realize a palm-sized micro aerial vehicle capable of autonomous flight. It has a wingspan of about 220 mm, a weight of 1.8 g with the drive motor and battery installed, and flaps at a frequency of 7 Hz. The results of flight motion analysis using a high-speed camera showed that this butterfly-style FMAV, which does not rely on an external power source and does not have a tail wing, can fly in a straight line while maintaining a constant altitude with an initial speed given. We were also able to observe the flight trajectory of it, which moved up and down with a flapping motion similar to that of a real butterfly. The development of an FMAV that can fly like an insect is important for the viewpoint of robotics to elucidate the posture control mechanism of insects, which still needs to be clarified. The autonomous flight of this butterfly-style FMAV is significant in this regard.

Hydrophytic ferns of the family Salviniaceae, such as those of the genus Salvinia, hold promise for application in water purification and bioassessment. The Salvinia species are known for their rapid growth, adaptability, resistance to adverse environmental conditions, and also their ability to adsorb pollutants. The manipulation of plant growth and development through the application of exogenous phytohormones is an effective technique. In laboratory settings, we investigated the impact of exogenous phytohormones and zinc sulfate on the morphophysiological characteristics of young sporophytes of Salvinia natans. During the phase of intensive growth, the addition of exogenous abscisic acid (ABA) at a concentration of 10−5 M to the growth medium inhibited the accumulation of biomass in S. natans sporophytes. However, gibberellic acid (GA3) and cytokinins (kinetin or zeatin) at a concentration of 10−6 M, along with indole-3-acetic acid (IAA) at a concentration of 10−5 M, induced a slight increase in biomass. In sporophytes of S. natans grown in a medium containing varying concentration of zinc sulfate (228, 114, 57, 28.5, and 14.25 mg of zinc per liter of water), sings of chlorosis in floating fronds were observed as early as the second day of cultivation, followed by symptoms of necrosis. There was a decrease in the content of photosynthetic pigments. Sporophyte biomass decreased, as zinc concentration increased, ranging from 9.6% to 51%. Simultaneous application of phytohormones with the highest concentration of zinc sulfate partially mitigated the adverse effects of the metal, reducing biomass degradation and sustaining sporophyte viability. Qualitative alterations in the fern phenotype were observed, highlighting the phytotoxicity of excessive zinc concentrations. This underscores the potential use of S. natans as a bioindicator for water pollution.

Unsettling Common Sense Assumptions about Intimate Partner Violence in the NICU
Authors: Klawetter Susanne , Wahab Stéphanie , Gievers Ladawna
Published: May 2024

NICU clinicians strive to provide family-centered care and often encounter complex and ethical challenges. Emerging evidence suggests that NICU clinicians likely interact with families experiencing intimate partner violence (IPV). However, little research and training exists to guide NICU clinicians in their thinking and practice in the midst of IPV. In this review, we use a structural violence framework to engage in a critical analysis of commonly held assumptions about IPV. These assumptions include an overreliance on binaries including male-female and offender-victim, the belief that people need to be rescued, prioritization of physical safety, and the notion that mandatory reporting helps families who experience violence. By reexamining these assumptions, this review guides NICU clinicians to consider alternatives to carceral and punitive responses to IPV, such as transformative justice and reflexive engagement.
Development, Characterisation and Biocompatibility Analysis of a Collagen-Gelatin-Hydroxyapatite Scaffold for Guided Bone Regeneration
Authors: Shankar Preethi , Arumugam Parkavi , Kannan Saranya
Published: May 2024

Guided Bone Regeneration (GBR) is the choice of treatment for improving the horizontal and vertical bone volume through bone grafting. GBR membranes work on the principle of preventing epithelial migration into the defect space while maintaining the space for cell migration and differentiation at the defect site. Hydroxyapatite has been commonly used as a bone graft for infrabony defects. The study was conducted at the Department of Biomaterials at Saveetha Dental College. GBR membrane was prepared and its material characterization was done using Scanning Electron Microscope (SEM), Energy Dispersive X-ray (EDX) analysis, Fourier Transform Infrared Radiation (FTIR), and Confocal Analysis. The developed GBR membrane revealed SEM properties conducive to cell attachment. EDX and FTIR analysis showed the successful development of the collagen-gelatin-hydroxyapatite membrane. Cell culture and confocal analysis revealed excellent biocompatibility with a homogenous layer of viable cells. The developed composite GBR membrane is a biogenic membrane with relevant biomineralization potential that should be applied for GBR applications.

Published: May 2024

Aim of the research - to analyze obstetric and perinatal complications of pregnancy and childbirth, the condition of newborn babies, pregnant women carriers of antibodies to thyroid peroxidase (TPOAb) in order to improve the effectiveness of their diagnosis and prevention. Materials and methods. A retrospective study was conducted of 140 histories of pregnancy and childbirth of women carriers of TPOAb, as well as the histories of their newborns - the main group (MG).The criteria for inclusion in the main group was the presence of an TPOAb titer higher than 100 IU/ml. The comparison group (CG) consisted of 40 birth histories of women without an elevated level of TPOAb, somatic pathology and with a physiological course of the gestational period, as well as 40 histories of their newborns. Statistical processing of research results was carried out using standard Microsoft Excel 5.0 and Statistica 6.0 programs. Results. It was established that female patients carrying TPOAb have a higher percentage of the following gestational complications: threats of termination of pregnancy (pregnancy in MG was terminated in 6 cases: frozen pregnancy in 2 (1.4%) cases, spontaneous abortion in the I trimester - 3 (2.1%) cases, spontaneous abortion in the II trimester - 1 (0.7%) case; threats of premature birth - 13 (9.3%) cases; fetal growth restriction syndrome - 8 (5.7%) cases; preeclampsia 22 (15.7%) cases against 2 (5.0%), p<0.001. Premature birth was observed only in MG patients and accounted for 24 (17.9%) cases. The rate of pathological labor was significantly different in the research groups. A high specific weight of pathological births childbirth was observed in women carriers of TPOAb - 47 (35.1%) cases in CG versus 4 (10.0%) cases in CG, p<0.05. Cesarean section was performed in 38 (27.1%) patients MG and 3 (7.5%) pregnant women CG. Conclusions. In the course of the retrospective study, it was revealed that women carriers of TPOAb have a higher percentage of the development of such gestational and perinatal complications as the threat of abortion and miscarriage, fetal distress, preeclampsia of various degrees of severity, pathological childbirth and asphyxia of newborns compared to patients with normal level of TPOAb. The research was conducted according to principles of the Declaration of Helsinki. The study protocol was approved by the Local Ethics Committee of the institution indicated in the work.The informed consent of women was obtained for conducting the study.

Extrahepatic portal vein obstruction (EHPVO) is an important cause of symptomatic portal hypertension (PH) in pediatric population. PH may lead to serious complications including variceal bleeding and hypersplenism. Literature data on infants under 12 months old with EHPVO is poor. Aim - to analyze our experience in treatment of children with symptomatic PH in children of the first year of life, the peculiarities of the course of EHPVO in them, and acknowledge readers with diagnostic algorithm of patients with EHPVO that ensures the timely start of treatment and reduce the risk of life-threatening complications. Materials and methods. 11 patients who were diagnosed with EHPVO before age of 12 month are included into the study. All patients underwent in-hospital treatment in National Specialized Children’s hospital “Okhmatdyt” in a period since 2006 to 2022. Results. Among 11 patients of the group, 7 (63.6%) were males. Mean age at diagnosis was 6.02±0.67 months. 9 (83.8%) patients had umbilical catheter in anamnesis. 7 (63.6%) patients manifested bleeding episodes. Ultrasonography and enhanced computed tomography was performed in all patients. Endoscopically all patients had high grade varices. 8 (72.7%) patients underwent surgical interventions. Median hospital stay duration in children with bleeding was 36 (95% CI: 28-56) days, and 17 (95% CI: 14-22) days in children without bleeding (p<0.003). The success of primary surgical interventions was assessed with Kaplan-Meyer test. Median overall survival was reached at 920 days after initial surgery; primary surgical intervention survival 0.417 (95% CI: 0.205-0.072). There was zero mortality in the study group. Conclusions. Newborns and infants with anamnesis of umbilical catheterization should be followed up closely by ultrasound imaging specialist. Patients with suspected PH are to be immediately referred to endoscopy and computed tomography in specialized center. Timely diagnosis, current endoscopic band ligation success in variceal bleeding primary prophylaxis would ensure further successful surgery and shorter hospital stay. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.

Introduction and Objectives: Food allergy has several negative nutritional consequences and may persist beyond the first year of lives. This study aimed to assess the role of a complete oral amino acid-based supplement in the diet of children on cow’s milk protein elimination diet because of food allergy.
Materials and Methods: This study included two groups of children aged 1–5 years paired by age and socioeconomic status: (1) study group, on cow’s milk protein elimination diet plus an oral amino acid-based supplement, and (2) control group, on cow’s milk protein elimination diet. Sociodemographic, clinical, anthropometric, and dietary data were obtained through online interviews. Two 24-h dietary recalls were collected on nonconsecutive days. Both groups comprised mostly boys.
Results: The study group presented lower values of body mass index. The frequency of feeding difficulties was similar between groups. The study group had a higher intake of energy, protein, carbohydrates, calcium, iron, zinc, phosphorus, magnesium, copper, selenium, vitamins D, E, B1, B2, B6, and B12, niacin, and folic acid compared to the control group. A higher proportion of children in the study group had adequate intake according to the recommendations made for energy, carbohydrates, iron, phosphorus, selenium, vitamins A, D, E, B1, B2, and B6, and folic acid.
Conclusions: The use of a complete oral amino acid-based supplement has a positive effect on the diet quality of preschoolers on cow’s milk elimination diet because of food allergy, promoting higher intake of energy, calcium, vitamin D, and other essential nutrients.

Published: May 2024

This study evaluated the effects of rice flour cakes enriched with wild fruit Prunus spinosa powder (PS) on techno-functional, nutrition, and eating quality. PS increases the cakes’ ash, protein, and moisture values. Total phenolic content increased from 35.91±0.25 to 73.39±0.58 mg GAE g-1, and gluten-free cakes’ antioxidant capacity markedly increased with the increasing level of PS powder addition (p<0.05). The increase in PS decreased the glycemic index (eGI), and the lowest eGI was determined as 69.38±1.21 in cake samples containing 4% PS. Except for the 1% PS added sample, the increase in PS caused a decrease in specific volume, % porosity, and increase in hardness, including four days of storage. The addition of PS increased the redness (a*) and decreased the yellow (b*) and brightness (L*) values. The flow behavior index (n) of cake batters containing 1% and 2% PS were similar to the control group. Cakes containing 1% PS received the highest scores in sensory analysis. Although the increase in PS amount negatively affects the textural properties of gluten-free rice flour cakes, it is crucial to increase its bioactive properties and nutritional values and positively contribute to health by reducing the glycemic index.
Lo que hace la gente con lo que ve: mediaciones y cultura ciudadana

Las comunicaciones mediáticas no son procesos horizontales, pero la recepción evidencia el poder de reflexión, transformación y creación por parte de la gente respecto a los contenidos, lo que enriquece las matrices culturales. Este artículo ofrece un análisis sobre la socialidad (Martín-Barbero, 2010) del microprograma de televisión El Súper Andino, emitido entre 2008 y 2009 por Aupan TV, canal comunitario del municipio de Andes, Antioquia, Colombia. Se abordó desde metodologías participativas y activas, que integraron la conversación y el debate para generar argumentación. El contraste entre los propósitos de la serie y la recepción permitió entender que toda práctica comunicativa está mediada por una negociación cultural que va cambiando con el tiempo.
Cine comunitario entre las relaciones de poder en prácticas audiovisuales contemporáneas

La memética y la desinformación por imágenes del ecosistema mediático contemporáneo
Authors:   Puce - Ecuador, López Paredes Marco
Published: May 2024

Vivimos en una sociedad imagética, donde el uso de artificios icónicos y visuales han ganado fuerza. Además, es una sociedad donde los ciudadanos producen sus propios contenidos y los hacen circular por sus canales en las redes sociales, diseminando ideas, filosofías, pensamientos y, en algunos casos, la desinformación. De ahí surge la memética, tema del estudio, y su inserción en el ecosistema mediático contemporáneo, puesto que la memética y la desinformación masiva resultan de la ecología de los medios en la cual vivimos, actualmente. Para el artículo, trabajamos, básicamente, con la investigación bibliográfica y, a partir de eso, desarrollamos una reflexión sobre la memética en el ecosistema mediático contemporáneo, así como su potencial conexión con la desinformación. Esperamos que el artículo, que tiene un carácter exploratorio, pueda ofrecer subsidios para diversas otras investigaciones.
Por una transformación colectiva del estudio de la comunicación.Una propuesta al 2030 desde Latinoamérica
Authors:   Ciespal, DÁVILA COBO Gissela
Published: May 2024

A partir del 2018, el Centro Internacional de Estudios Superiores de Comunicación para América Latina, CIESPAL, propone reflexionar desde Latinoamérica, las formas de producción y consumo de la comunicación. Entendiendo que las redes digitales y los desarrollos tecnológicos cambiaron el relacionamiento entre personas y medios; marcaron ritmos distintos en cuanto a producción, difusión y consumo de información; sobrexpusieron a la sociedad a una cantidad de información imposible de procesar; introdujeron algoritmos que definen, a la vez que vetan, los contenidos que nos muestra la red; y, contribuyeron a la paralización y aislamiento social, lo que trae como consecuencia una serie de trastornos psicológicos.

Comunicación y transición ecosocial para el bien común
Authors:   Universidad de Málaga, CHAPARRO ESCUDERO Universidad de Málaga , DE ANDRÉS Susana ,   Universal de Valladolid
Published: May 2024

Este artículo plantea la tesis de que la comunicación y sus tecnologías asociadas, como sistema cultural de mediación, pueden entenderse como bien común. Para ello, se revisa el concepto de bien común y se trenzan saberes populares y científicos. Se identifican algunas de las condiciones para teorizar la comunicación desde este nuevo marco: cooperación, decolonización y deliberación. El riesgo de los bienes comunes es su administración desde la búsqueda de beneficios privados o privativos. El desarrollo como deriva económica que implica sobreexplotación, crecimiento sin límites y beneficios privados, constituye una herramienta de herencia colonial que impulsa cambios sociales que no inciden en el bien común, beneficia a una élite internacional cada día más acaparadora de los recursos.
Pasado y presente de la investigación latinoamericana de la comunicación. Anotaciones para una agenda 2030
Authors:   FLACSO - Ecuador, RAMOS Isabel
Published: May 2024

El presente artículo propone una reflexión sobre los desafíos actuales del pensamiento crítico de la comunicación en América Latina y procura delinear una agenda de investigación hacia el 2030, partiendo del reconocimiento de los acumulados históricos de la llamada Escuela Latinoamericana de la Comunicación. Este ejercicio prospectivo toma como punto de partida las conclusiones de la primera reunión de especialistas y expertos latinoamericanos en Comunicación, que tuvo lugar en Costa Rica en septiembre de 1973, por iniciativa de CIESPAL, y pone en evidencia que el legado de este encuentro fundacional continúa vigente, 50 años después, en el trabajo de las redes regionales de investigadores e investigadoras. Los nuevos rostros de la dependencia cultural, las consecuencias de la plataformización del trabajo, el rol de la tecnología en la articulación de la palabra pública y el papel de los estudios críticos de Opinión Pública y Comunicación Política en la democratización de las sociedades latinoamericanas son algunos de los retos a enfrentar.
Educomunicación para la transformación: promoviendo la autoprotección en niñas y niños frente a las violencias
Authors:   Universidad Mayor de San Andrés, DÁVILA NAVARRO Edgar Gustavo
Published: May 2024

La violencia contra la niñez representa un problema de salud pública, por los altos niveles de recurrencia. La responsabilidad para naturalizar los hechos apunta a: el descuido, la escaza protección, la desinformación, el tratamiento mediático, las maneras de brindar disciplina y el escaso abordaje con las y los protagonistas de esta historia: niñas y niños. La educomunicación es un campo teórico práctico, que permitió abordar de manera interdisciplinar la problemática de la violencia hacia poblaciones infantiles en 3 municipios de Bolivia. También, involucró a actores principales otorgándoles corresponsabilidades y conocimientos apropiados para generar mecanismos de autoprotección, prevenir hechos de violencia física, psicológica y sexual, y promover la transformación de la vida de estas poblaciones, que, a menudo, se encuentran en situación de alta vulnerabilidad, logrando un manejo adecuado para reducir estos hechos.
