Authors: Jasim Al-Foa'adi Ala'a Hasan , Jubouri Mohammed Baqer Al-
Published: July 2022

Background: The patient's vital signs must stay stable pre a pulmonary function test since the approach demands the patient to breathe slowly and deeply and exhale quickly. However, events that cause variations in normal vital signs may impact the patient. Many strategies can be utilized to stabilize vital signs, including music treatment. The purpose of this study is to compare the effectiveness of music therapy on the vital signs of client's pre a pulmonary function test. Methods: An experimental design study with an application (pre-test, post-test), to determine the effectiveness of music therapy for clients pre pulmonary function test for 106 clients in Al-Diwaniyah, Al-Shamiya, and Al- Hamza public hospitals In Iraq. Participant's vital sings (pulse rate, respiratory rate, blood pressure and oxygen saturation) were measured before and after the intervention group. Two groups assigned as music interventions and a control group. Results: The results showed the difference in Pulse rate between pre and post- test were decrease in Music therapy group 6.32 b/m. While Systolic blood pressure and Diastolic blood pressure were increased in Music therapy group 3.17/ 2.22 mm/hg respectively. Also the results showed the respiratory rate was decreased in Music therapy group 2.07 b/m. While oxygen saturation was increased in Music therapy group 2.20. Conclusions: Listening to music pre pulmonary function test had a positive effect on the regulation or stability of vital signs. Age and body mass index have the most influence on the vital signs of the clients who listed to music pre pulmonary function test.

Öz
Giriş/Amaç:Akut transvers Miyelit (ATM), omuriliğin idiyopatik veya kordda kompresyon olmaksızın bir enfeksiyon veya sistemik hastalığa ikincil olarak fokal enflamasyonudur. Omuriliğin tam veya kısmi tutulum derecesine göre ekstremitelerde güçsüzlük, duyu kusuru, mesane ve rektumun otonomik bozukluğu ile karakterize akut veya subakut bir klinik tablo görülür.
Gereç ve Yöntemler: Bu çalışmada kliniğimizde yatarak izlenen 35 akut transvers miyelit hastasının dosyası retrospektif olarak incelendi. Dejeneratif omurilik kompresyonuna yol açan kompresif miyelopati ve intramedüller neoplazili olgular ile bilinen Multiple Skleroz tanısı olup miyelit epizodu ile başvuran olgular çalışmaya dahil edilmedi. Hastaların %31,4’ünde idiyopatik akut transvers miyelit saptanırken, %68,6’sında etiyolojik tanıya ulaşıldı. Hastalar idiyopatik ATM olguları ile idiyopatik olmayan ATM olguları şeklinde iki gruba ayrılarak gruplar arası demografik ve klinik özellikler, BOS inceleme sonuçları ve spinal MRG bulguları karşılaştırıldı
Bulgular:İdiyopatik ATM’li grubun yaş ortalaması idiyopatik olmayan ATM grubuna göre istatistiksel olarak anlamlı düzeyde düşük, ortalama semptom süresi daha kısa bulundu. Miyelit klinik bulguları açısından her iki grup arasında istatistiksel anlamlı bir farklılık saptanmadı. Oligoklonal band (OKB) pozitifliği idiyopatik olmayan ATM’li 5 hastada tespit edildi. Torakal omurilik yerleşimi her iki grupta da en sık görüldü. Ancak lezyon yerleşimi açısından gruplar arasında anlamlı istatistiksel farklılık saptanmadı. Uzun segment tutulum idiyopatik olmayan ATM grubunda %66,66 oranında, idiyopatik ATM grubunda ise %27,27 oranında görülmüş olup MRG’de tutulan segment bulguları açısından her iki grup arasında anlamlı istatistiksel farklılık saptandı
Sonuç:Transvers Miyelit nadir bir durum olmasına rağmen klinik tablo nörolojik bir acil durumdur ve pratik hızlı bir yaklaşım, spesifik etiyolojiye ve uygun tedaviye yönelik ipuçlarını ortaya koyar.

THE INFLUENCE OF SEASONS ON METAL BIOACCUMULATIONAND OXIDATIVE STRESS IN SENTINEL ORGANISMS IN SOUTHAFRICAN URBAN FORESTS
Authors: NAUDÉ A
Published: July 2022

Variations in Al, Fe and Mn concentrations in soil, leaf litter, moss, lichen and pill millipedes, as well as the induced oxidative stress effect of metals on the organisms, between the dry and the wet season within two Afromontane forests in the Western Cape were investigated. The two forests in the closest proximity of the Cape Town city centre and urban pollution sources were chosen to determine the difference of metal contamination between the dry, hot and cold, wet season. Three sampling sites were chosen within each forest at different altitudes on Table Mountain, as well asa control site, where the soil, leaf litter and each organism were randomly collected in both the dry and the wet seasons for metal and biochemical analysis. The metals in the wet season in both of the forests showed higher concentrations, as did the forest closest to the Cape Town city centre.This is indicative of higher levels of pollution due to increased anthropogenic activities in the wetseason. Oxidative stress in organisms was apparent in the varying tGSH levels, of which the dryseason mostly revealed the higher concentrations. Oxidative lipid damage (measured as MDA) levels were generally increased during the wet season when the metal concentrations were higher as a result of prominent brown haze episodes in winter. Urban forest ecosystems in urban cities may suffer irreparable damage resulting from metal contamination, more so in the colder wet season.

Biosorption is an alternative technology developed to overcome pollution, including heavy metal contamination in aquatic ecosystems. The accuracy of choosing a biosorbent strongly influences the success of biosorption. The organisms that are widely developed as biosorbents are microbes. Microbes live in ecosystems by forming biofilms. Therefore, knowledge related to the mechanism of heavy metal adsorption, such as Hg(II) by biofilms, will contribute to the development ofbiofilm-based biosorption. This study aims to analyze the biosorption characteristics of Hg(II) bybiofilms taken from aquatic ecosystems. The methods used are kinetic adsorption analysis, isotherm adsorption analysis, and FTIR spectra analysis of biofilms. This study indicates that the adsorption process of Hg(II) into the biofilm is a physicochemical process. The adsorption sites that bind Hg(II) are negatively charged sites resulting from the ionization of functional groups such as carboxyl groups present in polymeric biofilms. According to this study, biofilm is an excellent biosorbent to adsorb pollutants such as Hg(II) from aquatic ecosystems.

Effective management strategy is required for handling the large quantities of waste produced by various societies/ organizations and waste characterization is essential to prepare this management policy. In this study, solid wastes collected from the combined campus of Chaudhary Charan Singh Haryana Agriculture University (CCSHAU) and Lala Lajpat Rai University of Veterinary and Animal Science (LUVAS), Hisar was characterized through population estimation, field investigations and applying ASTM D5231-92 standard method. In the combined campus, the average quantity of solid waste generation was found to be 1047.1Â±214.4 kg/day. The whole campus was divided into five structural units and waste composition was determined, mixture unit waste comprised the highest fraction of food 62.13% and polythene 10.8%. The statistical estimation obtained a strong positive correlation of mixture unit waste with residential and markets waste contents, which was 0.995 and 0.997 at p<0.01. The analysis of solid samples showed that the biodegradable part of solid waste may be a better source for composting while some content of non-biodegradable waste can be sold into the market for recycle or reuse purpose. On the basis of solid waste characterization, a set of recommendations were suggested to strengthen the waste management processes for institutions.

Published: July 2022

At the toll plaza, vehicle operation, including acceleration and deceleration, emit more pollutants and takes longer to cross the area, with the highest level of pollution being generated during this period. As a result, the workers are exposed to numerous sorts of pollution for an extended periodof time throughout their workday. In the present study, we monitored probable contaminants inside the toll plaza in order to assess the morbidity conditions of these individuals as a result of chronic exposures at the workplace. Personal measurements of particulate matter (PM), total volatile organic carbons (VOCs) and carbon monoxide (CO), and polyaromatic hydrocarbons (PAHs)-particulate phase were considered to determine exposure. The mean work shift dustconcentration of PM2.5 and PM10 readings were within the permissible level of Indian standards (PM2.5 60 Î¼g/m3 and PM10 100 Î¼g/m3) but exceed the WHO recommended guideline (PM2.5 15 Î¼g/m3and PM10 45 Î¼g/m3). The maximum CO concentration was 2.65 ppm, while the lowest was 0.31ppm.Lesser aerodynamic particulate matter of PM1 and PM4 and gases, which were monitored, have norecognised standards. H2S concentrations ranged from 0.06 to 2.00 ppm, while VOC concentrations ranged from 0.08 to 0.41ppm. Total PAHs were found in the range of 2.10-24.81 Î¼g/m3 and Benzo [ï¡] Pyrene (BaP) was identified in the range of 2.10-7.60 g Î¼g/m3 in each sample. Headache (66 %), back pain (60.4 %), coughing (54.7 %), hair fall (41.5%), tearing (32.2 %), itching eyes (32.2 %), joint pain (28.3 %), congestion in the nose (17%), sore throat (%), and neck pain (15.1 %) were the mostcommon health problems reported by toll plaza workers.

Authors: Bhise Santoshkumar , Jain Amit , Jain Ravi
Published: July 2022

Background: The conventional surgical model is recently questioned via the statement that there is continuity in the mesentery. The concept stating the mesentery regress seems to be accurate with the latest literature stating continuity of mesentery to rectum from the duodenojejunal junction in radiological as well as surgical findings. Aims: The present trial on cadavers was done to evaluate and access the efficacy of this newly developed technique in preserving the continuity of the mesentery and ex-vivo mesentery characterization. Materials and Methods: In 16 cadavers, a newly developed dissection technique by Kumar A et al was adopted for judging and assessing the continuity of the mesentery. The whole mesentery is separated from the abdominal cavity. These observations were recorded photographically and clinically, and the results are formulated. Results: The continuity of the mesentery was continuous and this finding was uniform in all the 16 cadavers examined in the study. As this continuity continued from mesoduodenom to mesorectum, this showed and pointed towards the intestine location at the intestinal margin of the mesentery. With this continuity, the study also depicted that anatomical boundaries that divide the various regions were not prominent on examination.

Published: July 2022

Tuberculosis is the one of the leading cause of death. Efforts are needed to develop new anti-tuberculosis medicines with alternative scaffolds because the current antibiotics are increasingly becoming ineffective against M. tuberculosis. In this study, 21 novel di hydro pyrimidinone derivatives were designed and synthesized to arrive at potentially effective anti-tubercular agents. Molecular docking studies were conducted on Mtb thymidylate kinase of Mycobacterium tuberculosis H37Rv (PDB ID 5NQ5). The enzyme active sites were docked with the title compounds after they were energy-minimized. According to their docking scores and binding energies, the ligands were ordered. The molecular docking results for the title compounds with Mycobacterium TB thymidylate kinase are very promising. Thymidylate kinase appears to be inhibited by 17c and 20c, according to the study.

The widespread use of “electronic health record systems (EHRs)” in health care provides a large amount of real-world data, opening up new opportunities for medical trials. “Deep learning, a subset of machine learning (ML)”, has experienced a meteoric rise in popularity over the last six years, owing to advances in computing power and the accessibility of enormous new datasets. “Natural language processing (NLP)” approaches have been used as an “artificial intelligence strategy” to obtain information from medical narratives in EHRs, as a huge quantity of useful clinical knowledge is contained in clinical stories. This NLP capacity may enable “automated chart review in clinical care to identify individuals with distinct clinical features” and decrease methodological heterogeneity in establishing “phenotypes, masking biological heterogeneity in allergy, asthma, and immunology research”. Aim of this research paper is to understand the advanced technologies such as “Machine Learning, Natural Language Programming” are helpful for digital health field. In this context, secondary data collection method is used to gather information related to this topic.

Authors: Swadika N , Suvitha S , Brindha Brindha
Published: July 2022

Background: Initially the concept of pain was emotional rather than a sensory modality. The word pain is acquired from the Greek word poine which means “penalty”.1 The International Association for the Study of Pain (IASP) described pain as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage”.2 Peripheral nerve blocks have become a popular anaesthetic option in the perioperative management of patients because nerve blocks provide better postoperative analgesia than does general anaesthesia, while avoiding the cardiopulmonary and central nervous system effects of general anaesthesia. Peripheral nerve block is a technique which uses local anaesthetic to be deposited around a target nerve and block the conduction of action potential thus not allowing pain signals to be transmitted to the pain centre in the brain. Materials & methods: A prospective randomised single blinded study was conducted at Vinayaka Missions Kirupananda Variyar Medical College & Hospitals, Salem from December 2019 to May 2021.
review on absorption enhancer and bioenhancer
Authors: Wadhwa S. , Gupta Mukesh
Published: July 2022

Poor permeability of orally administered drugs is the major factor limiting the bioavailability of orally administered drugs. The unique barrier properties of the gastro-intestinal membrane, intestinal and presystemic metabolism, intersubject variability also contributors to poor permeability and bioavailability of the drugs. Bioenhancer can benefit the drugs with this problem, especially BCS class III and class IV drugs. Different mechanisms have been established to understand the permeation enhancement effect of different permeation enhancers; their understanding can facilitate the selection of suitable absorption promoters for drugs having specific physicochemical properties. However, certain issues associated with development of absorption promoter technology like lack of in vitro and in vivo correlation of efficacy, reproducibility, and safety. Therefore instead of chemical permeation enhancer herbal bioenhancer is more acceptable due to their better safety profile.

A new proof of the Gasca - Maeztu conjecture for n = 5
Authors: Vardanyan G.
Published: July 2022

An n-correct node set X is called GCn set if the fundamental polynomial of each
node is a product of n linear factors. In 1982 Gasca and Maeztu conjectured that for every GCn set there is a line passing through n + 1 of its nodes. So far, this conjecture has been confirmed only for n ≤ 5. The case n = 4, was first proved by J. R. Busch [3]. Several other proofs have been published since then. For the case n = 5 there is only one proof by H. Hakopian, K. Jetter and G. Zimmermann (Numer Math 127:685–713, 2014). Here we give a second proof, which largely follows the first one but is much shorter and simpler.

Abstract. The uniqueness problems of the j-th derivative of a meromorphic function f(z)
and the k-th derivative of its shift f(z + c) are investigated in this paper, where j, k are integers with 0 ⩽ j < k. We show that when f (j) (z) and f (k) (z + c) share one IM value and two partially shared values CM, the uniqueness result remains valid under some additional hypotheses. With one CM value and two partially shared values CM, a uniqueness theorem about the j-th derivative of f(z) and the k-th derivative of its shift f(z + c) is also proved.
A novel secure deep ensemble learning protocol based on Conjugacy search problem homomorphic encryption scheme
Authors: Dung Luong The , Tho Hoang Duc , Anh Nguyen Hoang , Tu Tran Anh
Published: July 2022

Abstract—Nowadays, machine learning and deep learning have been widely employed. User privacy is an issue to consider in problems such as medicine, and finance. Machine learning models not only require accurate predictions but also ensure the privacy and security of data for users. In this paper, we propose a method to ensure the privacy for training and using deep learning models that employs a homomorphic encryption scheme based on the conjugate search problem. This method implements encryption on the data before transferring them to a cloud server, which stores local deep learning models from participants to predict the encrypted data, then the encrypted prediction results are sent back to users, and they perform decryption to get the model’s prediction result. These results can also be assembled to create a new training dataset for a model from the client. It is evident that our proposed model on the MNIST dataset produces an accuracy over 98% with some very simple network architectures and approximates the accuracy of centralized complex models, which does not ensure privacy.

Abstract—Today, Elliptic Curve Cryptography (ECC) has many practical applications. ECC was a direction in lightweight primitive cryptography. This paper is based on the arithmetic idea of an Elliptic curve. Elliptic curve arithmetic can be used to develop Elliptic curve encryption schemes such as key exchange, encryption, and digital signature. Compared with traditional cryptosystems with the same level of security, Elliptic curve cryptography has a smaller key size, reducing processing costs. To encode the Vietnamese text, we are based on the sound of Vietnamese characters to make a table of these characters’ order. In the present paper, we apply a new encryption algorithm with a public key using an Elliptic curve over finite fields on our proposed Elliptic curve equation.Tóm tắt—Ngày nay, mật mã đường cong Elliptic (ECC) có nhiều ứng dụng trong thực tế.

In über 80 Folgen spielen Moritz und seine Freunde gegen ihre Rivalen und gewinnen Pokale, Turniere und Meisterschaften. Die Jungs werden dabei auch von einigen Mädchen unterstützt, die im Team spielen und sich sogar als Co-Trainerinnen engagieren. Die rund zehnjährigen Kinder treffen sich daneben zum Eisessen, in der Schule oder im Fussballtraining und kämpfen mit ihren Alltagssorgen. Fast ohne erwachsene Bezugspersonen bewegen sie sich durch eine überraschend brutale Welt voller Intrigen, Verbrechen und Hass. Wer zum falschen Team gehört, wird verachtet. In der In-group der Mannschaft ist das Leistungsprinzip zentral. Wer nicht gut trainiert oder Fehler macht, wird ausgeschlossen. Die Hörspielserie lebt von einer Fussballmedienrealität, die immer wieder in Form von Live-Schaltungen in die alltägliche Welt der Kinder (und der Hörer*innen) eindringt. Da sind alle Sorgen vergessen und die Teufelskicker Stars, die von ihren Anhänger*innen in vollen Fussballstadien angefeuert werden.In diesem Beitrag wird eine exemplarische Auswahl von Folgen mittels close readingeiner qualitativen Inhaltsanalyse unterzogen. Dabei beleuchtet werden die Themenfelder Identitätsbildung, Liebe und Hass, Sexismus und Rassismus, Körperlichkeit, Fankultur, Erfolg und Niederlagen, Teambildung und Zusammenarbeit. Der Blick hinter die bunte Fassade zeigt, dass die Hörspielserie die Kinder an eine Fussballmedienrealität des passiv bleibenden Publikums heranführt und ein streng konservatives heteronormatives Wertesystem einführt, in dem Männlichkeit dominiert. Die Hörspiele zeichnen sich zudem durch eine Doppelmoral aus: Während vordergründig jede Form von Hass, Rassismus und Sexismus verurteilt wird, sind diese dennoch ständig präsent.

Die BBC-Produktion Merlin (2008-2012) inszeniert ein Prequel-Setting mit einem adoleszenten, noch unerfahrenen Merlin, der den gleichaltrigen Arthur auf seinem Werdegang zum vorherbestimmten König begleiten und unterstützen soll. Im Verlauf von fünf Staffeln werden der Lernprozess und die Reise eines anfänglich noch ignoranten und egozentrischen Arthurs, der sich des Elends seines zukünftigen Volks noch nicht bewusst ist, und seine Entwicklung zum gerechten Herrscher über ein egalitäres Königreich illustriert. Treu an seiner Seite steht Merlin, der sich angesichts der gesetzlich verordneten Hetzjagd auf die Magie in Camelot davor hüten muss, seine Zauberkräfte einzusetzen. Zudem spielen die Macher*innen der Serie bewusst mit den Erwartungen des Publikums, bestätigen oder untergraben Annahmen bezüglich des Schicksals der allseits bekannten Figuren und kreieren somit eine originelle und erfrischende Adaption. Nichtsdestotrotz verfällt die Serie besonders in späteren Episoden in alte Muster und verwehrt den Figuren eine Loslösung von bisherigen Darstellungen.

Indem zeitgenössische soziopolitische Konflikte Grossbritanniens adressiert werden, wie die ethnische, religiöse und sexuelle Vielfalt, verweist BBC auf die Zeitlosigkeit und Aktualität des Artusstoffes. Merlin setzt sich zwar mit der Diskriminierung marginalisierter Gruppen, mit Klassenunterschieden und unfairen Geschlechterverhältnissen auseinander, tut dies allerdings nicht in allzu ausführlicher Manier, da es vordergründing familientaugliche Unterhaltung sein soll. Dennoch entwirft die Serie zumindest den utopischen Traum einer besseren, toleranteren Welt, lässt allerdings die Frage offen, ob Grossbritannien diesen Punkt mittlerweile erreicht hat, oder noch immer auf die Rückkehr des ‚Once and Future King‘ wartet.
Der amerikanische Alptraum

Dieser Beitrag setzt sich mit der dystopischen – Gegenentwurf einer Utopie – Darstellung der US-amerikanischen Gesellschaft in dem in Vergessenheit geratenen Exil- bzw. DDR-Kinder- und Jugendliteraturklassiker Sally Bleistift in Amerika. Eine Geschichte aus dem Jahre 1934 (1935) von Auguste Lazar auseinander.

Dieses Werk handelt hauptsächlich von der russischjüdischen Frau namens Sally Bleistift, die das russische Reich verlassen musste, um den dortigen Pogromen zu entkommen. Sie lebt seitdem mit ihrer Enkelin in einer US-Arbeiterstadt und hat zudem einen Ersteinwohnerknaben grossgezogen. Am Anfang der Geschichte nimmt sie ein Schwarzes Findelkind bei sich auf. Die Präsenz von Figuren aus verschiedenen ethnischen Gruppen dient dazu, von deren jeweiligen Geschichte zu berichten.

Da die Darstellung Lazars an historische Fakten und ideologische Gründen anknüpft, wird im ersten Teil des Beitrags der Entstehungskontext dieser Erzählung thematisiert. Das Hauptaugenmerk der darauffolgenden Teile liegt auf dystopischen Elementen der US-amerikanischen Gesellschaft für die verschiedenen abgebildeten diskriminierten Minderheiten. In der Tat kommen die

Diskriminierungsformen, denen sie ausgesetzt sind, auf verschiedene Art zum Ausdruck. Insbesondere die von der Polizei ausgehende antisemitische Rhetorik, sowie der Ausschluss der Ersteinwohnernationen und die der Schwarzamerikanischen Gemeinschaft auferlegten Rassensegregation und deren Folgen sollen untersucht werden. Im letzten Teil werden die Implikationen dieser negativen Darstellung der US-Gesellschaft analysiert.
Wenn die Angst im Bilderbuch umgeht...
Authors: Von Stockar-Bridel Denise
Published: July 2022

Seit der zweiten Hälfte des 20. Jahrhunderts interessiert sich die traditionsgemäss pädagogisch und utopisch ausgerichtete Kinderliteratur immer mehr für die kindliche Realität in ihrer ganzen Komplexität und Konflikthaftigkeit. Besonders das Bilderbuch wird zu einem privilegierten Medium für wirkungsvolle Inszenierungen von psychischen Phänomenen und Prozessen. Dank seiner doppelten Sprache – der graphischen und der literarischen – vermag es, komplexe Empfindungen und Erfahrungen in anschauliche Bilder und einfache Worte zu fassen, indem es sie spiegelt oder metaphorisch gestaltet.

Zu den thematisierten Affekten gehören die entwicklungsspezifischen Ängste, die entsprechend ihrer grossen Rolle im kindlichen Leben einen wichtigen Platz in der zeitgenössischen Bilderbuchliteratur einnehmen.  Dabei können zwei Kategorien unterschieden werden: Verschiedene Titel thematisieren objekthafte, beziehungsbezogene Ängste, die in systemischer Optik dann aufkommen, wenn das Kind dem Anderen begegnet, mit dem es sich auseinandersetzen muss. Zahlreicher noch sind die Titel, welche subjekthafte, innerpsychische Ängste inszenieren, die in psychodynamischer Perspektive die kindlichen Bemühungen begleiten, zwischen den Bedürfnissen seiner Innenwelt und den Anforderungen der Aussenwelt zu vermitteln; zu diesen gehören die Angst vor Trennung und Vernichtung, die Angst vor den eigenen unkontrollierbaren Affekten und vor allem vor dem Verlust der elterlichen Liebe.

Interessante Ausnahmen bilden Bilderbücher, welche die existentielle Angst vor dem Leben, respektive Tod – oder grundsätzliche Strategien zur Bewältigung von Angst gestalten. Grundsätzlich überzeugen diejenigen Bilderbücher, welche die subjektiven Angsterfahrungen ihrer Helden und Heldinnen jeweils mit ihrer lebenswichtigen Beziehung zu den Eltern oder wichtigen Bezugspersonen in Verbindung bringen.

Bilderbücher können kleine Kinder beim persönlichen Umgang mit Angst unterstützen, wenn sie, von Erwachsenen vermittelt, zu Katalysatoren Angst bewältigender Prozesse werden und damit einen Schonraum schaffen, in dem das Kind mit Hilfe seiner noch sehr lebendigen Fantasie eigene Strategien zur Bekämpfung von Angst zu entwickeln vermag.

Althergebrachte Schreckgestalten wie Geister, Graf Dracula oder Frankensteins Monster haben einen festen Platz im populärkulturellen Gedächtnis. Durch zitierende Neuinterpretationen werden die Figuren jeweils an verschiedene kulturelle Befindlichkeiten und Zuschauergruppen angepasst und finden auch den Weg in heimelige Kinderzimmer. Längst sind die Monster nicht mehr nur Schreckensbringer, sondern auch Sympathieträger und fungieren als Projektionsflächen für diverse bewusste und unbewusste Ängste – auch für Heranwachsende.

Der Beitrag folgt diesen Monsterfiguren anhand von vier Filmen: Igor (2008), Hotel Transylvania (2012), ParaNorman (2012) und Frankenweenie (2012). Es wird versucht zu klären, weshalb diese ehemals ernsten Feindbilder in kindliche Imaginationswelten transportiert werden und welchen Zweck sie im Kinderzimmer erfüllen. Es zeigt sich, dass die Stoffe durch den Rückgriff auf populärkulturell verankerte Figuren Kinder wie auch Erwachsene ansprechen und verschiedene Lesarten anbieten. Die Hauptbotschaften sind dabei in den betrachteten Stoffen dieselben.

Einerseits wird auf das gefährliche Potential von gesellschaftlich tabuisierten Ängsten verwiesen. Durch die normierte Ausklammerung von Schmerz, Frustration oder Tod können sich diese zu brodelnden Gewaltpotentialen entwickeln, welche sich auf willkommene Feinbilder projizieren lassen und so Monster erst hervorbringen – es entsteht eine Spirale der Furcht. Andererseits richtet sich der Fokus auf die Beziehung von Eltern und Kindern im Spannungsfeld des Erwachsen-Werdens in einer disziplinierenden Gesellschaft. Kinder werden ermuntert an ihrer Fantasie, ihren Träumen und letztlich ihrer Individualität festzuhalten. Sie sollen sich nicht aufgrund der antizipierten Verrohung vor dem Erwachsen-Werden fürchten.

Die Erziehenden wiederum bekommen einen kritisch reflektierenden Spiegel vorgehalten. Sie werden ermahnt den Heranwachsenden mannigfache Freiheiten zu gewähren und sie in ihrer empathischen Emotionalität und kreativen Eigensinnigkeit zu stärken. So werden die Monster in der Kinderstube zu den Anwälten der Jugend, die im Angesicht einer normierenden, sanktionierenden, exkludierenden und opportunistischen Gesellschaft für freie Entfaltung, Selbstwirksamkeit und die Handlungskompetenz von Kindern eintreten.

Seit den 1960er-Jahren haben sich zunehmend fiktionale Bilderbuchgeschichten entwickelt, die sportliche Erzählkontexte für ihre Handlungsverläufe und Darstellungsanliegen nutzen. Dabei fallen einerseits Aussagen und Deutungen zu Sport und Bewegung als Teil der kindlichen Lebenswelt an, andererseits werden Anliegen gestaltet, die über den Sport hinausweisen. Der Beitrag vermittelt einen Überblick über die vorherrschenden Thematiken in sportbezogenen Bilderbuchgeschichten. Zu diesem Zweck wurden aus dem Zeitraum der letzten 45 Jahre 197 Titel ausgewählt und auf ihre zentralen Erzählanliegen hin verdichtet. Das Untersuchungskorpus konnte weitgehend sieben thematischen Rubriken zugeordnet werden, und zwar: Sich anstrengen, Ziele verfolgen; Fair sein, altruistisch handeln; Siegersein relativieren, Gemeinschaft schätzen; Angst überwinden, Mut entwickeln; Geschlechterrollen aufbrechen, Mädchen stärken; Zu hoch hinaus wollen, in Sport vernarrt sein; Bewegungsdrang ausleben, von Bewegungsfreude angesteckt werden. Der Beitrag illustriert an einer Reihe von Beispielen, wie die Bücher gemäss der jeweiligen Rubrizierung ihre thematischen Anliegen umsetzen. Es wird allerdings auch auf Bilderbücher aufmerksam gemacht, die sich nur schwerlich dem gefundenen Themenraster zuordnen lassen, weil sie eine besonders komplexe Erzählstruktur aufweisen und andere thematische Intentionen verfolgen.
Im Stil spontaner Momentaufnahmen

Sport und Sportlichkeit bilden in Kinder- und Jugendzeichnungen des 20. Jahrhunderts und darüber hinaus einen schier unerschöpflichen Themenfundus, dessen Bandbreite sich zwischen Wettkampf und Freizeitaktivität, Schulturnen und olympischen Siegesträumen erstreckt. Darstellungen bewunderter Sportler, spannende Momente in einem Spiel oder Rennen, das alltägliche Schulturnen oder auch das Turnen mit der Familie wurden im Lauf der Jahrzehnte in Bildern gefasst und bei einschlägigen Wettbewerben zum Thema „Sport“ oder bei Zeichenwettbewerben „nach Natur“ oder „nach Phantasie“ eingereicht. Die Motivation zu eigener sportlicher Betätigung war gleichbedeutend mit der ästhetischen Reflexion von Sportlichkeit im Bild. „Sport“ wurde dabei zu einem Sammelbecken höchst unterschiedlicher sportlicher wie auch spielerischer Betätigungen. Extrembergsteiger werden ebenso darunter gefasst wie sonntägliche Wanderer. Profisportler und -sportlerinnen fanden in charakteristischen Posen wie der „Biellmann-Pirouette“ nicht nur zahlreiche jugendliche Nachahmerinnen, sondern auch in den Bildern ihren deutlichen Widerhall. Der Einfluss von Medienbildern ist oftmals unverkennbar, erfährt aber eine Umdeutung in der Zeichnungen, welche das Augenmerk auf Bewegungsstudien richtem. Spannende Momente, eindrückliche Posen und aussergewöhnliche Blickpunkte charakterisieren die Zeichnungen. Die Bewunderung international berühmter Athleten findet ebenso Anerkennung in den Bildern wie der Traum vom eigenen sportlichen Erfolg. Sport vor dem Hintergrund von internationalem, politisch motiviertem Wettbewerbsgedanken findet zumindest indirekt ein Echo in den Zeichnungen, im Vordergrund steht in den Bildern jedoch das selbst erlebte oder erträumte Sporterlebnis.
