Kama lateral dişlerin direkt kompozit veneer restorasyonlarla tedavisi: olgu sunumu
Authors: KARAKAŞ Mert , ARISU Hacer Deniz
Published: December 2022

Kama lateraller, dental anomalilerle ilişkili olabilen, sıklıkla maksiller dişlerde rastlanan, normalden küçük, silindirik, sivri şekillere sahip olabilen dişlerdir. Tedavisinde seramik veya kompozit veneer restorasyonlar kullanılabilir. Seramik restorasyonlar doğal diş dokusunun daha fazla kaybına neden olması, maliyetli olması ve tamirinin zor olması nedeniyle, kama lateral tedavisinde ilk seçenek olarak tavsiye edilmemektedir. Bu vakada bilateral şekilde kama laterallere sahip hasta estetik beklentilerle kliniğimize başvurmuştur. Yapılan intraoral ve radyolojik muayenelerin ardından hastaya tedavi seçenekleri anlatıldı ve hasta isteği doğrultusunda direkt kompozit veneer uygulanmasına karar verildi. Diş rengi belirlendi ve uygun kompozit rezin seçildi. Dişlerin tüm yüzeyleri %37 ortofosforik asitle pürüzlendirildi ve tüm yüzeylere 2 aşamalı total etch adeziv sistem uygulandı. Kompozit, dişlerin doğal konturlarına ve bitiş çizgilerine uygun şekilde yerleştirildi ve tedavi tek seansta tamamlandı. Daha sonra restorasyonların yüzeyleri özel bitirme frezleri ve polisaj diskleriyle düzenlendi. Bu olgu sunumunun amacı, kama laterallerin direkt kompozit veneerlerle estetik bir şekilde tedavi edilmesini amaçlamaktadır.

Laminate Veneerler

Estetik dental tedavilerde hastaların beklenti ve gereksinimleri günden güne artmaktadır. Dental estetik, hastaların kaybettikleri estetik görüntünün yeniden kazandırılmasında son derece önemli bir yer tutmaktadır. Hasta beklentilerinin bu denli yüksek olması, hekimleri tedavilerde daha estetik materyaller kullanmaya ve daha hassas tedavi uygulamalarına itmektedir. Laminate veneerler hastalara kaybettikleri estetik görüntüyü yeniden kazandırma noktasında minimal invaziv tedavilerin başında yer almaktadır. Geçmişten günümüze laminate veneer uygulamalarında farklı materyaller, farklı teknik ve yaklaşımlar söz konusu olmuştur. Günümüzde bu uygulamalar ile yapılan tedavilerde yüksek klinik başarı oranları elde edilmekte, geliştirilen sistemlerle birlikte çok yüksek sağ kalım oranları kaydedilmektedir. Laminate veneer tedavilerinde teşhis ve planlama ile birlikte hasta koordinasyonu, doğru materyal ve teknik seçimiyle birlikte laboratuvar iletişimi de klinik başarıda anahtar faktörlerden birkaçı olmaktadır. Bu literatür derlemesinin amacı; laminate veneerler konusunda geniş ve güncel çalışmaları aktararak, kullanılan materyaller, teknik ve uygulamalar hakkında bilgi vermektir.

Published: December 2022

Amaç: Nazopalatin kanalın (NPK) farklı morfolojik tipleri bulunmaktadır. Bu çalışmanın amacı; NPK morfolojisinin konik ışınlı bilgisayarlı tomografi (KIBT) görüntüleri üzerinden morfolojik olarak değerlendirmektir.

Gereç ve Yöntemler: Rastgele seçilen 500 hastanın KIBT görüntüleri retrospektif olarak taranmıştır. Sagittal kesit üzerinde yapılan incelemede hastaların yaş ve cinsiyetlerine göre NPK morfolojik tipleri (silindirik, ağaç dalı, kum saati, huni, muz ve konik) incelenmiştir.

Bulgular: Bu çalışmada 269’u kadın, 231’i erkek olmak üzere toplam 500 kişinin KIBT görüntüsünde NPK incelenmiştir. Beş yüz bireyin 127’sinin silindirik (%25.4), 87’sinin huni (%17.4), 72’si kum saati (%14.4), 60’ı (%12) muz şeklinde ve 27’si (% 5.4) ağaç dalı şeklinde NPK formuna sahip olduğu tespit edilmiştir. Yirmi ve altı yaş grubunda yer alan kadınlarda muz tipi görülmezken %36.4 ile en yüksek oranda konik tip NPK izlenmiştir. Üçüncü dekatta ise kadınlarda (%32.5) ve erkeklerde (%27.5) en çok silindirik tip NPK izlenmektedir. Dördüncü dekatta ise kadınlarda %2.94 oran ile muz tipi, erkeklerde ise ağaç dalı ve huni tipi %7.84 ile en az oranda görülmektedir. Beşinci dekatta kadınlarda ve erkeklerde en çok silindirik ve huni tip görülmüş ve ağaç dalı formunda NPK her iki cinsiyette de görülmemiştir. Altıncı dekatta ise huni formda NPK her iki cinsiyette de görülmemiştir.

Sonuç: Maksilla anterior bölgede cerrahi operasyonlar öncesinde, anatomik ve morfometrik açıdan NPK tiplerinin KIBT ile incelenmesi önemlidir. Her iki cinsiyette de silindir ve konik tip NPK fazladır.

Authors: ABAKLI İNCİ Merve , ÖZER Hazal , KESKİN Ümran
Published: December 2022

Mineral trioksit agregat (MTA), esas olarak kalsiyum ve silikat elementlerinden oluşan biyoaktif endodontik bir simandır. 1990' larda Torabinejad tarafından tanıtılmış, 1997' de ise Amerika Birleşik Devletleri'nde kullanılmak üzere Gıda ve İlaç İdaresi (FDA) tarafından onaylanmıştır. MTA; sement gelişimine olanak tanıyan ve periodontal ligament hücrelerinde rejenerasyon sağlayan ilk restoratif materyaldir. Biyouyumlu bir materyal olan MTA, düşük sitotoksisiteye sahiptir. Apeks dışına taştığı durumlarda minimal inflamasyona neden olur. Odontoblastik tabaka oluşumu sayesinde dentin köprüsü oluşumunu indükler. Pulpal fibroblastlardan sitokin salınımını uyarır, bu da sert doku oluşumunu stimüle ederek hücrelerin hızlı büyümesini destekler. İlk olarak retrograd dolgu materyali olarak kullanılmaya başlayan MTA; daha sonra pulpa kuafaj tedavileri, iatrojenik ve furkasyon perforasyonlarının tamiri, retine süt dişlerinin kök kanal tedavisi, apeksifikasyon sırasında bariyer oluşturulması, devital beyazlatmada bariyer gibi çeşitli klinik uygulamalarda da kullanım alanı bulmuştur. MTA’ nın biyouyumluluk, sızdırmazlık, pulpa ve periradiküler dokuların rejenerasyonunu artırma kapasitesi gibi özellikleri; dental kullanım alanlarındaki çeşitliliği ve klinik başarı oranlarını artmasını sağlamış ve bu yenilikçi yapısıyla klinisyenlerin ilgi odağı haline gelmiştir. Dişte renk değişikliğine sebep olması ve sertleşme süresindeki değişiklikler başlıca dezavantajlarıdır. Yapılan in vitro çalışmalar başarılı sonuçlar vermiş olsa da; uzun dönem başarısının desteklenmesi amacıyla kontrollü klinik çalışmalara ihtiyaç duyulmaktadır.

Bu literatür derlemesinde, MTA’ nın fiziksel, kimyasal, biyolojik ve antimikrobiyal özellikleri, klinik uygulama şekilleri ve güncel formülasyonları sunulmaktadır.

El objetivo del estudio fue describir las características demográficas de los animales de compañía (caninos y felinos) identificados con dispositivos electrónicos en los distritos de Lince y San Borja, Lima-Perú, en el periodo 2013- 2021. El estudio observacional descriptivo recabó información de distrito, especie, sexo, raza, tamaño, fecha de nacimiento, condición reproductiva, domicilio y programa de vacunación de los animales identificados con dispositivos electrónicos registrados en la base de datos del Registro Nacional de Identidad Animal (RENIAN). Se recuperó información de 782 animales. El 24% de los animales pertenecían al distrito de Lince y el 76% a San Borja. El 83.5% fueron canes y 16.5% felinos. La mayor proporción de canes se identificó y registró en 2019 (74.4%) y los felinos en 2021 (63.4%). La cantidad de animales registrados con relación a la población de canes y felinos estimada fue <5%. La edad actualizada al 22 de febrero del 2022 registró una media de 5.5 ± 0.2 años en caninos y de 3.8 ± 0.5 años en felinos. Predominaron animales machos entre canes (56.1%) y felinos (55.8%); así como de raza pura (66.1%) entre los canes y mestiza (82.2%) entre los felinos. El 21% de los canes y el 63.6% de los felinos estaban esterilizados. El registro de vacunación se encontraba desactualizado. La práctica de identificación de los animales de compañía en base a dispositivos electrónicos en los distritos de Lince y San Borja es escasa, con lo que el conocimiento de los patrones demográficos y epidemiológicos es limitado afectando las potenciales intervenciones de interés en salud pública.
The stability of a stochastic discrete SIVS epidemic model with general nonlinear incidence
Authors: Wen Buyu , Teng Zhidong , Liu Bing
Published: December 2022

In this paper, based on Euler–Marryama method and theory of stochastic processes, a stochastic discrete SIVS epidemic model with general nonlinear incidence and vaccination is proposed by adding random perturbation and then discretizing the corresponding stochastic differential equation model. Firstly, the basic properties of continuous and discrete deterministic SIVS epidemic models are obtained. Then a criterion on the asymptotic mean-square stability of zero solution for a general linear stochastic difference system is established. As the applications of this criterion, the sufficient conditions on the stability in probability of the disease-free and endemic equilibria for the stochastic discrete SIVS epidemic model are obtained. The numerical simulations are given to illustrate the theoretical results.
Coleolus carbonarius Demanet, 1938 (incertae sedis) from the late Bashkirian (Carboniferous) of the Donets Basin
Authors:   Institute of Geological Sciences, NAS of Ukraine (Kyiv, Ukraine), Dernov Vitaly
Published: December 2022

Problematic fossils Coleolus carbonarius Demanet, 1938 were described from seven localities of the Mospyne Formation (late Bashkirian, Carboniferous) of the central Donets Basin. Many authors attributed these conoidal fossils to various groups of animals, including worms, conulariids, pteropods, hyoliths, tentaculitids, gastropods, scaphopods, and other molluscs without specifying the class, as well as phyllocarids. Representatives of the genus Coleolus cannot belong to the scaphopods because the apex of their tube is closed. The aperture of the tube in living Coleolus is directed upwards, while in scaphopods it is directed downwards. The belonging of Coleolus to pteropods was challenged by previous authors. The assignment of Coleolus to Coniconchia is also incorrect, because the shells of Coniconchia have chambers, which are absent in Coleolidae. The ecological and some morphological characteristics of Coleolus indicate their proximity to sedentary polychaete annelids (Sedentaria) or phoronids (Phoronida). Almost all Coleolus remains come from sediments that formed in a shallow marine environment with a low sedimentation rate and contamination of the bottom silt and, possibly, the bottom layer of the water column with hydrogen sulphide. Coleolus carbonarius, according to all of the obtained data, was a semi-infaunal animal. The apical end of the tube was deeply immersed into the semi-liquid clayey silt. Only a small part of the tube protruded above the surface. The characteristic transverse ornament of the tube surface, possibly, increased the contact area of the unstable semi-liquid clayey silt and the tube and further stabilized the vertical position of the animal in the bottom sediment. The sedentary lifestyle of Coleolus apparently suggests that these animals fed on planktonic organisms and organic detritus suspended in the water column. This type of feeding is possible only in the presence of a developed hunting apparatus. The morphology of the tubes of Coleolus carbonarius Demanet, 1938 is described in the article, including the structure of their apical end and aperture. Traces of damage caused during the lifetime of animals on the apical part of their tube are also studied.
Factors influencing habitat choice of bird species: a comparative study of the ornithofauna of a natural and an artificial wetland

Between 2019 and 2022, we studied the avifauna and environmental conditions of two wet-land habitats located in close proximity to each other in Transcarpathia (nearby to the village of Dyida, Zakarpatska Oblast, Ukraine)—one being a natural, currently protected but drying and highly degraded former bog (Tóvár Ornithological Reserve), whereas the other one being an ar-tificial pit lake (Lake Dyida). Lake Dyida is used as a beach and recreation area during the summer nesting season of birds. Both of these wetlands border with agricultural lands. Bird species that occur in both of the investigated habitats are affected by severe anthropogenic disturbances. A total of 27 795 individuals of 58 bird species from 34 families were observed in the two areas over the four study years. Results indicate that the species composition of the two study sites differed considerably, both on annual and seasonal basis. Seasonal precipitation totals strongly influence the current spatial ratios of terrestrial and waterbird species, and show a strong positive correlation with the seasonal total number of bird species. Maximum numbers of birds are recorded in spring and summer at Tóvár and in autumn and winter at Lake Dyida. In the case of Lake Dyida, these could partly be due to the autumn–winter appearance of migratory waterbirds and the end of the beach season. Despite the impact of numerous anthro-pogenic factors and habitat distrubances, the natural wetland is much more species-rich even in its degraded condition than the artificial wetland, which has been confirmed not only for bird species but also for plant species in the two areas. The obtained results revealed that duck spe-cies consider the deep-water pit lake as an alternative habitat during periods of drought, but for waders the great water depth makes this site less exploitable. In Europe, too, drying out due to seasonal precipitation shortages is an issue of increasing concern, especially for wetlands bea-cuse artificially maintained lakes and reservoirs cannot fully take over the role of natural lakes, marshes and bogs, which will have severe consequences for nature protection and species con-servation in the future.

The results of studies of chemical pollution (Pb, Zn) of perennial grasses—Elymus repens L., Artemisia absinthium L., and Hypericum perforatum L.—on background plots and within the areas of impact of industrial enterprises in Kropyvnytskyi (Ukraine) are presented. It is noted that chemical pollution is the most dangerous. The activity of enterprises is considered, in the result of which heavy metals enter the air. Testing of plants (stems and leaves) was carried out at a distance of 10–100 m from the enterprises. The content of heavy metals in the aboveground part of plants was analysed by atomic absorption spectrophotometer in the laboratory of the Department of Exploratory and Ecological Geochemistry, IGMR NAS of Ukraine. The comparison of sorption properties of different plants in the same phases of development allowed plants with bioindication capabilities to be identified. The results of the analysis showed that plants most effectively accumulate the maximum amount of heavy metals from the atmospheric air at the end of the summer dormancy phase (second half of August). At this time the plant requires the minimum amount of nutrients that it takes from the soil. Stems and leaves of perennial grasses actively accumulate aerosols and fine dust on their surface due to plant secretions with the formation of a mucous film that actively adsorbs heavy metal ions. The background, minimum, and maximum content of heavy metals in plants is determined. Comparing the content of heavy metals in plant samples in the background and study plots, it was found that E. repens near industrial enterprises is the most effective bioindicator of air pollution. In order to determine the level of atmospheric air pollution using bioindication methods, the index of plant contamination (Sр) was proposed, which is the ratio of concentration coefficient of heavy metals and their amount. An assessment scale for atmospheric air pollution with heavy metals has been developed based on the contamination index (Sр) of bioindicator plants: the degree of pollution is 1–3—weak, 3–6—medium, 6–9—strong, more than 9—very strong. The proposed coefficients allow for conducting a situational assessment of atmospheric air pollution with heavy metals using bioindication methods.
Canonical quasi-geodesic mappings of special pseudo-Riemannian spaces
Authors: Kurbatova Irina , Pistruil M.
Published: December 2022

The present paper continues the study of quasi-geodesic mappings f:(Vn, gij, Fih) → (V'n,g'ij, Fih) of pseudo-Riemannian spaces Vn, V'n with a generalized-recurrent structure Fih of parabolic type. By a generalized recurrent structure of parabolic type on Vn we mean an almost Hermitian affinor structure of parabolic type for which the covariant derivative of the structural affinor Fih satisfies the condition F(i,j)h=q(i Fj)h.
In the previous paper by the authors [Proc. Intern. Geom. Center, 13:3 (2020) 18-32] it was proved that the class of pseudo-Riemannian spaces with generalized-recurrent structure of parabolic type is closed with respect to the considered mappings and the generalized recurrence vectors in (Vn, gij,Fih) and (V'_n, g'ij, Fih) may be distinct. In this article, it is assumed that the mapping f preserves the generalized recurrence vector qi.
We construct geometric objects that are invariant under the quasi-geodesic mapping of generalized-recurrent spaces of parabolic type and recurrent-parabolic spaces. A number of conditions are given on these objects, which lead to the fact that a generalized-recurrent space of parabolic type admits a parabolic K-structure, and a recurrent-parabolic space admits a Kählerian structure of parabolic type.
We study special types of these mappings that preserve some tensors of an intrinsic nature.

A method was proposed for the synthesis of substituted 2-(2-(furan-2-carbonyl)hydrazono)-4-oxobutanoic acids by the reaction of substituted 2,4-dioxobut-2-enoic acids with furan-2-carbohydrazide. It was found that substituted 2-(2-(furan-2-carbonyl)hydrazono)-4-oxobutanoic acids undergo intramolecular cyclization in the presence of propionic anhydride to form the corresponding N'-(2-oxofuran-3(2H)-ylidene)furan-2-carbohydrazides. The anti-inflammatory activity of the obtained compounds was studied. It was found that the obtained compounds have pronounced anti-inflammatory activity.

Published: December 2022

At present, the development of portable devices for the express assessment of the content of biologically active objects, such as antioxidants, is one of the relevant technological problems of modern chemistry, medicine, and engineering. The main advantages of such devices are the simplicity and rapidity of analysis, small volumes of analyte, as well as miniaturization of equipment, making it possible to carry out the on-site analysis and, thus, to take a step towards the personalized medicine. The potentiometric method using the K3[Fe(CN)6]/K4[Fe(CN)6] system, which in the laboratory-scale version proved to be the most accurate, reproducible, and express, was the basis for the developed prototypes of portable devices. In this study, two versions of prototypes of the portable device are proposed, namely, the open microcell with the 0.2 ml volume and the microfluidic device with flow control. The correctness of the antioxidant capacity (AOC) determination in both systems was confirmed by comparing the results of the "introduced-found" method on model solutions of antioxidants and their mixtures with the AOC results obtained in a standard laboratory electrochemical cell. The relative standard deviation did not exceed 10%. The AOC of some beverage industry was determined using the microfluidic device. The correlation coefficient of the results, obtained in the microfluidic device and the laboratory cell, was 0.90, which indicates good data convergence and the possibility of using the potentiometric method implemented in the microfluidic device to assess the AOC of multicomponent objects.
Historical Fact as a Place of Memory: P. Nora and Research into the Local Pasty
Authors:   Ural Federal University, Golovashina O. V.
Published: December 2022

Noting the difficulties in the definition of the concept of historical fact and the problems associated with the historical fact in regional history, the author proposes to refer to the discursive apparatus of P. Nora. The author proceeds from the fact that the places of memory, about which the French historian wrote, can be seen as a theoretical lens, the use of which will allow to contrast the operational attitude to history comprehension and grasping of the past. The article noted the difficulties in translating the concept of 'places of memory', the influence of predecessors (E. Lavisse, F. Braudel, M. Foucault, W. Benjamin as well as M. Halbwachs and F. Yeats) and justified that the project of places of memory was aimed at revising the previously established concept of the nation. Relying mainly on the texts of P. Norа, the author reaches the following conclusions. 1. The discursiveness of memory sites allows to contrast them with the conventional state historical narrative and traditions of historiography. The historical fact in this interpretation escapes unambiguous interpretations, being not part of the mechanism of constructed state history, but acts as an actor of local history, the history of groups, communities. 2. Historical facts as places of memory can be thought of as a kind of "remains" of the past which, despite the plurality of interpretations, retain their significance. This avoids a highly constructivist interpretation of historical fact. 3. The changes characteristic of places of memory allow us to consider the historical fact in a dynamic way.
Creative Strategies of Ural Pipe Companies: Between Technological Heroism and Memorialization
Authors:   Ural Federal University, Bugrov K. D.
Published: December 2022

The paper investigates the development of concept of authenticity in industrial cities. The author analyzes the presentation strategies pursued by the key enterprises of the Ural tube industry, as embodied in material (urban planning and industrial complexes) and verbal (historical narrative) forms. For those plants established in the 1930–1940s, namely, Pervouralsk Novotrubny and Chelyabinsk Pipe Rolling Plants, the main strategy was technological heroism associated with unique projects and recent reindustrialization. In contrast to them, the Seversky Pipe Plant, which switched to the production of tube only in the 1960s, built a representation around historical continuity in relation to the “mining civilization” of the Urals by preserving the place of historical memory – the blast furnaces of the 19th century. The author concludes that the historical differences in the narratives about enterprises affect the practices of their positioning in the urban environment, and, consequently, the very concept of authenticity, which in turn is required for the successful formation of the experience economy.
The Interaction of the Memory of Migrants and the Hosting Community as a Factor in the Development of Regional Identity: the Case of the Kemerovo Region
Authors:   Financial University under the Government of the Russian Federation, Andrisenko S. A. ,   Lomonosov Moscow State University
Published: December 2022

The subject of the study is the interaction of the cultural memory of migrants and the hosting community. The object of the study is a case of such interaction in the Kemerovo region. The Kuzbass regional authorities support the work of national public associations, through which migrants can support the practices of the country of origin, and also create cultural centers to involve members of the host community in the cultural practices of migrants. Also, the cultural policy of the region involves the involvement of national organizations in urban and regional cultural and educational events. Such a strategy of working with migrants makes it possible to reduce the conflict potential of a multinational entity. The basis for the formation of regional identity is the industrial specifics of the region, which unites all residents of the region, regardless of nationality.

The purpose of the work is to analyze the theoretical and practical aspects of mnemonic adaptation and integration of migrants in the Republic of Tatarstan, a Russian region with its own complex landscape of memory. The sources of the research are the materials of the activity of The House of Friendship of Nations in Kazan. The methodological basis of the article is constructivism. The results of the study note the primordial basis of official historical representations. The autonomy of narratives about the past of “local” and “newcomers” and different significance of historical views for the “young” and “senior” is stated. The connection between contradictions in the social and historical policies of The House of Friendship of Nations is revealed. The conclusions of the article offer practical recommendations for activating the processes of “mnemonic” adaptation and integration of migrants, the main of which is the actualization of their family memory.
Russian Campaign in the Memory of France in the Second Half of the XIX Century: between "Memory-Victory" and "Memory-Injury"
Authors:   Ural State Pedagogical University, Postnikova A. A.
Published: December 2022

This article examines the process of transforming the image of Napoleon's Russian campaign in the historical memory of the French in the second half of the 19th century. The author, having analyzed the image of war in the space of historical politics, art, periodicals, historical science, came to the conclusion that excessive state intervention in the process of constructing the past leads to the destruction of "heroic myths." So, with the fall of the regime of the Second Empire in the consciousness of society, a trip to Russia began to be perceived as the result of the fatal mistake of the emperor. During the years of the Third Republic, the image of war continued to develop in public discourse, demonstrating a kind of historical pattern when imperial ambitions inevitably lead the nation to tragedy.
Multiplicadores fiscais no Brasil identificados com restrições de sinais e de zeros
Authors: Abreu Thiago Felipe Ramos de , Lima Elcyon Caiado Rocha
Published: December 2022

Resumo O objetivo deste trabalho é aferir a eficácia da política fiscal no Brasil, obtendo os impactos de suas inovações e calculando seus multiplicadores. Foi adotado um modelo de Vetor Autorregressivo Estrutural Bayesiano com uma identificação inovadora, proposta por Arias et al. (2018), ao qual, além de restrições de sinais, se impõem também restrições de zeros nas Funções Impulso Resposta (FIRs), de modo que é possível identificar choques em que as variáveis de interesse respondam de forma positiva, negativa ou nula. Tal inovação metodológica evita ambiguidades na identificação dos choques fiscais e possibilita verificar se seus impactos são significativamente afetados quando o orçamento do governo se mantém constante. Os resultados apontam que a identificação das inovações fiscais com restrições de sinais e de zeros só permite chegar a multiplicadores fiscais significativos no curto prazo e que somente com a adição de restrições de zeros sobre o PIB é possível chegar a valores dos multiplicadores consistentes com a literatura econômica. O estudo indica, também, uma contribuição significativa das restrições de zeros na identificação dos multiplicadores fiscais.

A Pesquisa Narrativa é uma metodologia que consiste na coleta de histórias sobre um determinado assunto em busca de informações para entender um fenômeno específico. Em geral, ela é utilizada como um recurso para dar voz aos sujeitos do estudo. Neste artigo, apresentamos um exemplo de como a Pesquisa Narrativa pode ser utilizada como uma alternativa aos tradicionais estudos de recepção na área da audiodescrição (AD). Para tanto, nos debruçamos sobre o percurso metodológico da tese de doutoramento intitulada Para além do visível: princípios para uma audiodescrição menos visocêntrica, na qual foram analisadas duas autobiografias de autoria de pessoas com cegueira adquirida: Touching the Rock, de John Hull, e Out of Darkness: A Memoir, de Zoltan Torey. As obras foram estudadas a partir da metodologia da Pesquisa Narrativa e os dados foram trabalhados através da análise temática nos moldes propostos por Braun e Clarke. A análise empreendida enfatizou a importância, entre outros, do respeito aos diferentes perfis do público-alvo, de uma exposição de qualidade, precoce e continuada, e da associação da AD a experiências multissensoriais.

Sözlükte “ortaya çıkmak, açılmak, kalp gözünün açılması” manalarındaki keşf kelimesinden türeyen mükâşefe, sûfîlere göre “duyular tarafından hissedilemeyen şeylerin riyâzet ve mücâhede yoluyla açığa çıkarılması” şeklinde tanımlanmıştır. Mükâşefe kavramı bizzat Kur’ân’da yer almamakla birlikte türediği keşf kelimesi temel alındığında sıkıntının bertaraf edilmesi , musibetlerin giderilmesi ve bir şeyi görülür kılmak anlamına gelecek şekilde kullanıldığı görülür. Kelime manası itibariyle görmeyi ifade eden müşâhede hakkında ise “Hakk’ın töhmet olmadan görülmesi, eşyanın tevhidin delilleri üzerine görülmesi ve birtakım tecellilerin görülmesi” şeklinde tanımlar yapılmıştır.

Objectives

Female marriage before age 18 is a global health issue related to gender inequality, but it is understudied in Canada. This study examined marriage trends among mothers aged < 18 versus older mothers and the sociodemographic correlates of marriage among adolescent mothers aged < 18 and older adolescent mothers.

Methods

Using the Canadian Vital Statistics – Birth Database, marriage prevalence was estimated by maternal age groups (< 18-year, 18–19-year, 20–24-year, and 25–49-year) between 1989–1990 and 2017–2018 (n = 10,399,250). Multivariable logistic regression was then used to examine the sociodemographic characteristics associated with marriage within adolescent maternal age group (< 18-year, 18–19-year, and 20–24-year) among births registered between 2000 and 2018.

Results

From 1989–1990 to 2017–2018, marriage prevalence declined 80.5%, 60.2%, 47.3%, and 16.0% in the < 18-year, 18–19-year, 20–24-year, and 25–49-year groups, respectively. Within the < 18-year, 18–19-year, and 20–24-year adolescent maternal age groups, older maternal age, larger parental age gap, foreign-born parents, rurality, and earlier birth period were associated with higher adjusted odds of marriage. Higher maternal neighbourhood income was associated with marriage among births to mothers aged 18–19 and 20–24 years but not among those to mothers aged < 18 years.

Conclusion

Marriage prevalence declined among mothers of all ages, but the shifts away from marriage appear stronger among younger mothers. The sociodemographic correlates of marriage are generally similar among mothers below age 18 and slightly older adolescent mothers.

Study purpose. This study aimed to examine the wall and pair models: (1) the difference in the effect of wall and pair exercises on Sepak sila (2) the difference between the high and low balance on Sepak sila (3) the interaction of wall and pair models with a high and low balance on Sepak sila skills.
Materials and methods. The method used in this research was a 2x2 factorial experiment. The research participants included 24 male students who took extracurricular sepak takraw aged 14-15 years with a height of 153-170± centimeters and a weight of 50-60 kilograms. The instruments used in this study were modified bass test balance instruments and Sepak sila instruments. Data collection techniques consisted of observation and tests. The data obtained were analyzed using a two-way Anova with the help of SPSS 20.
Results. (1) There was a significant difference in effect between the wall and pair training models on Sepak sila skills with F 19.698 and sig. 0.000 <0.05. Based on the findings, the paired model was found to be better with an average of 46.17 compared to the model on the wall which obtained an average of 41.50. (2) It was found that there was a significant difference in effect between the high and low balance on Sepak sila skills where high balance was better with an average of 46.33 compared to low balance with an average of 41.33. (3) It was found that there was a significant interaction between the wall-mounted and paired exercise models with a high and low balance on Sepak sila skills with F 130.251 and sig. 0.000<0.05.
Conclusions. In conclusion, the paired exercise model is better than the wall exercise model. As a result, it is advised to use a paired model to strengthen the fundamental technical skills of Sepak sila.

The purpose of this study to find out the relationship of selected physical and angular kinematical variables with the performance of toe-touch skill among male kabaddi players (raiders).
Materials and methods. One hundred male raiders were selected for this study. The age of the participants ranged between 18 and 25 years. The selected physical variable, i.e. lower extremity explosive strength was measured by the standing broad jump test. Selected angular kinematical variables were measured by the software ‘Kinovea version-0.9.3’. The toe-touch skill performed by raiders was measured by three experts’ rating. The inter-rater reliability of the scores awarded by the experts to the participants was tested by Cohen’s Kappa test and the Kappa coefficient was found significant.
Results. Spearman’s rank correlation revealed that there was significant correlation in case of lower extremity explosive strength (rs = .259, p = .009), angle at leading leg ankle joint (rs = .327, p = .001) variables and there was no significant correlation in case of angle at trailing leg ankle joint (rs = .016, p = .871), angle at leading leg knee joint (rs = .23, p= .823), angle at trailing leg knee joint (rs = -.171, p = .089) and angle at hip joint (rs = -.195, p = .052) variables with the performance of toe-touch skill in kabaddi.
Conclusions. The study concludes that lower extremity explosive strength and the angle at the leading leg ankle joint positively contribute to toe-touch skill performance in male kabaddi players.

Published: December 2022

The study purpose was to analyse the peak EMG at five upper-body muscles during four different jab techniques in youth boxers.

Materials and methods. Male youth national-level boxers (n=7) were assessed for peak electromyography (EMG) of anterior deltoid (AD), biceps brachii (BB), triceps brachii (TB), flexor carpi radialis (FCR), and upper trapezius (UT) while performing four jab techniques: long-range targeting head (LRH), long-range targeting body (LRB), medium-range targeting head (MRH), and medium-range targeting body (MRB).

Results. The LRH induced the highest EMG for AD (2092.9±411.9) and BB (1392.0±687.3). The MRB induced the highest EMG for the FCR (1337.16±538.28), TB (1589.3±600.3), and UT (1221.2±507.5). However, between jab techniques, only the AD showed a significant (p<0.001) different EMG. Specifically, the LRH induced greater AD EMG compared to LRB (157.5 [p<0.001]), MRH (411.0 [p=0.003]), and MRB (398.3 [p=0.010]). Further, the LRB induced greater AD EMG compared to MRH (253.5 [p=0.024]) and MRB (240.8 [p=0.049]). The MRH and MRB (-12.7 [p=0.911]) induced similar AD EMG.

Conclusions. Peak EMG at five upper-body muscles varies between jab techniques. However, the differences seem relatively small, except for the AD muscle, with a descending pattern of peak EMG for the LRH > LRB > MRH and MRB jab techniques.

Sport and fitness are physical requirements in the same way that humans require food and water. On the other hand, sport and fitness is a highly complex field of study, complicating attempts to define critical terms, resulting in a relative lack of scientometric analysis.
The study goal is to look at the development of sport and fitness research around the world, using the Scopus and Web of Science databases as its foundation.
Materials and methods. Publications are gathered using the Scopus and Web of Science databases as well as scientometric parameters, including worldwide publication trends, the authors who receive the most citations, the amount of citations, and author keywords.
Results. The results show the authors’ keywords analysis was inspected based on their relationship to physical activity, physical exercise, and physical training. The United States was the most active country, with 601 publications. As expected, the United States is a leader in physical activity promotion, with 19.3 percent of the population participating in sports and exercising daily in 2019. The International Journal of Environmental Research and Public Health from Switzerland leads 68 publications, which is another noteworthy finding. Additionally, according to this analysis, Ortega, F.B., of the School of Medicine, University of Granada, Madrid, Spain, is the author who publishes the most documents with 33 in total.
Conclusions. According to our research, the top five keywords that gained traction over the previous two years were "Cardiorespiratory Fitness," "Body Composition," "Health," "Physical Activity," and "Adolescents." The study value to the field of sports and fitness is that it provides readers and upcoming researchers with a wide range of sports and fitness trends from the past and present. Additionally, the study findings will aid future academics in predicting potential industry trends.
