Fine-dining Restoranlarda Müşteri Memnuniyetini Etkileyen Unsurların Belirlenmesi: Netnografik Bir Araştırma
Authors: KANDEMİR ALTUNEL Gizem , ÇİFÇİ İbrahim
Published: December 2021

Fine-dining restoran anlayışının dünya genelinde yaygınlaşmaya başlamasıyla birlikte bu alan turizm yazınında daha fazla ilgi görmeye başlamıştır. Ancak, restoran işletmeleri ile ilgili müşteri memnuniyetini belirleyici unsurları ortaya koyan çalışmaların yoğunluğuna kıyasla fine-dining restorancılık anlayışına yönelik henüz yeterince araştırma yapılmamıştır. Bu araştırmanın amacı, fine-dining restoranlarda müşteri memnuniyetini etkileyen unsurların belirlenmesidir. Bu amaç doğrultusunda, Türkiye’nin en çok ziyaretçi alan üç ilinde (Antalya, İstanbul, Muğla) faaliyet gösteren fine-dining restoranların Tripadvisor yorumları incelenmiştir. Araştırmada yöntem olarak netnografi yaklaşımı tercih edilmiş ve çevrimiçi yorumlar içerik analizine tabi tutulmuştur. Keşfedici nitelik taşıyan bu araştırmada incelenen 193 adet olumlu müşteri yorumu sonucunda seçici kodlama yöntemi ile 579 adet ifade belirlenmiştir. Netnografik yaklaşım yardımıyla analize tabi tutulan yorumlar neticesinde, fine-dining restoranlarda müşteri memnuniyetini etkileyen unsurlar birbirleriyle ilişkili dört ana kategoride toplanmıştır; yiyecek-içecek özellikleri, atmosfer, hizmet personeli ve fiyat-kalite uyumu. Araştırmada ayrıca fine-dining restoranlarda müşteri memnuniyetini etkileyen en önemli unsur yiyecek içecek özellikleri olarak ön plana çıkmıştır. Her ana boyut kendi içerisinde müşteri memnuniyetini belirleyen etkenlerle açıklanmıştır. Fine-dining restoranlarında müşteri memnuniyetini etkileyen birbiriyle ilişkili birden çok stratejik faktör incelenmiş ve önemli bazı yönetimsel ve araştırma sonuçları vurgulanmıştır. Gerçekleştirilen bu araştırma fine-dining restoran müşterilerinin memnuniyetini etkileyen unsurları ortaya koymaktadır. Bununla birlikte fine-dining restoranların rakiplerine göre güçlü, zayıf yönlerini ve konumlarını belirleyebilmesine imkân sağlamaktadır.

Authors: Hamzić Marta , Fuerst Bjeliš Borna
Published: December 2021

This paper presents an analysis and definition of development types and subtypes in the landscape of Central Lika, based on processes of change in the period 1980−2012 CORINE Land Cover database data for 1980 and 2012 were used to establish the landscape types in Central Lika in those years. The landscape types in Central Lika were determined according to land cover/land use. Based on the mutual relations between the established landscape types in the two observed years, we established six landscape development types and three subtypes in Central Lika. The spatial distribution of landscape development types and subtypes in Central Lika was determined using the Standard Deviational Ellipse (Directional Distribution) spatial analysis method. The results obtained showed that in the observation period (1980−2012), most of the area of Central Lika (89.46%) belonged to the Stagnation landscape type. Other development types were present to a much lesser extent (about 5.5%) and were found to be Vegetation succession, Agrarisation, Vegetation degradation and Built-up land. We established a spatial gradation of three phases in the process of vegetation succession, that is, development subtypes from the centre to the margins of the research area. At the same time, in the observation period, the process and trend of extensification of land use in Central Lika was twice as present as intensification.
RADYASYON YAYMA ve ATOM ENERJİSİYLE PATLAMAYA SEBEBİYET VERME SUÇLARINA BİLİMSEL ve HUKUKİ PERSPEKTİFTEN BİR BAKIŞ
Authors: EGE Ahmet
Published: December 2021

Radyasyon ve nükleer enerji iyi ellerde olduğunda insanlığa sağlık, enerji ve refah getiren fakat kötü ellerde bir o kadar tehlikeli ve zarar veren enerji türüdür. Türkiye’nin nükleer enerjiyle elektrik üretimine geçiş sürecinde olduğu bu yıllarda radyasyon yayma ve atom enerjisiyle patlamaya sebebiyet verme suçlarının geniş bir bilimsel ve hukuki perspektifle analiz edilmesi büyük önem taşımaktadır. Böyle bir analizde fizik, kimya gibi temel bilimler ve mühendislik bilimleri ile tıp ve hukuk iç içe girecektir. Söz konusu suçların hukuki değerlendirmesinde bilimsel temellere oturmayan bir tutum, yanlış bir sonuca yol açarak kişilerin hiç işlemedikleri bir suç nedeniyle cezalandırılmalarına neden olabileceği gibi suç işlenmesine karşın faillerin cezalandırılmamalarına da neden olabilir.

Radyasyon yayma suçu nükleer maddelerle işlenebileceği gibi nükleer silahlarla da işlenebilir. Atom enerjisiyle patlamaya sebebiyet verme suçunu kişilerin, terör gruplarının veya yasa dışı örgütlerin nükleer silah yaparak suç işlemeleri pratikte imkansıza yakındır. Tarihte meydana gelen üç büyük nükleer kaza olan; Three Mile Island (1979-ABD), Çernobil (1986-Sovyetler Birliği) ve Fukushima (2011-Japonya) kazalarında doğrudan atom enerjisi (nükleer) kökenli bir patlama olmamıştır. Patlamalar ikincil nitelikteki kimyasal reaksiyonlarla gerçekleşmiştir. Buna karşın reaktör içerisindeki nükleer bölünme ürünlerinin etrafa yayılmasının ne denli ciddi sonuçları olduğu konunun uzmanı olsun olmasın herkesin malumudur. Bu bağlamda atom enerjisiyle patlamaya sebebiyet verme suçu aynı zamanda radyasyon yayma suçuna da yol açmaktadır. Patlama sonucu etrafa saçılan parçalar radyoaktivite içereceğinden bu suçun kasten veya taksirle işlenmesi halinde aynı zamanda radyasyon yayma suçu da işlenmiş olmaktadır.
THERMOHYDRAULIC DISTRIBUTION IN TWISTED MICRO HEAT EXCHANGERS MOUNTED IN ANNULAR CHANNELS
Authors: Tuz V.O. , Lebed N.L.
Published: December 2021

The design of twisted heat exchangers provides a possibility to compensate for temperature and mechanical stresses thus ensuring continuous and failsafe operation of the equipment. The authors use fins and multiturn pipe bundles to reduce the mass and size characteristics of the heat exchangers. Such design significantly complicates the calculating method. The main aspect of swirling flows is the presence of radial and axial pressure gradients. When vapor or gas flows swirl, the flow velocity near the walls is much higher than the average values, while at the axis the flow is significantly slower and in some cases its values can become negative. The liquid flowing near the axis has a notably lower pressure, which can cause it to boil. Considerable radial gradients of axial and rotational speed, as well as static pressure contribute to turbulent pulsations. Given that the working fluid flows along a helical line, the flow in the near-wall area is similar to the flow around curved surfaces. The study analyses how the pipe bundle geometry impacts hydraulic distribution and scrutinizes the main components of pressure loss in the twisted heat exchanger. The analysis allowed simplifying the method of hydraulic calculation of the multiturn twisted heat exchanger. Solving the outer heat transfer and hydrodynamics problem for the twisted heat exchanger allowed determining the effect of the main factors and the relationship between the parameters of the coolant and the working mass on the distribution values. The paper presents the equations for determining geometry of the pipes with different coiling diameters, as well as the equation for finding hydraulic distribution in individual pipes in the layers of the pipe bundle. The obtained results can help increase the accuracy of thermal calculation. The authors propose to use sectioning of twisted heat exchangers as a way to reduce hydraulic distribution.

Authors: Grande-López Víctor
Published: December 2021

Cada vez más, preadolescentes y adolescentes están preocupados por la imagen que proyectan a través de Internet. Desde el ámbito de la educomunicación, como vehículo de transmisión de conocimientos a través del medio, se pretende analizar tres películas sobre las relaciones virtuales a través de adolescentes, para concienciar sobre los riesgos que pueden surgir en esa interacción. Para ello, se hace referencia al procedimiento metodológico utilizado para un film, desde las teorías sobre la narrativa fílmica y la semiótica del relato. Donde se tiene en cuenta: los riesgos que existen en Internet como eje argumental en las historias, su intención comunicativa y el valor que aportan desde sus líneas transversales. Una persona es libre de hacer lo que quiera con su cuerpo y exhibir sus intimidades a través de Internet, pero es necesario conocer que existen riesgos en dicha exposición virtual, y uno de ellos, son los cibercriminales que necesitan conseguir contenidos sexuales de menores, para luego venderlos a plataformas con gran demanda de pedófilos y pederastas.

Taking advantage of the benefits associated with the fourth stage of the industrial revolution--quite often termed as the “era of digitalization” in the wider literature--has become a main priority for ports globally, as part of their further development. The implications of smart technologies on the sustainable development of the ports have not been adequately addressed by the existing literature and it is exactly this gap that this study aims to fulfil. This paper aims to provide an overview of the innovative technologies adopted by a small number of smart ports around the world and highlight their link to sustainable development by employing an exploratory review of various sources. The design features of the smart ports identified by the existing literature have formed the basis for the development of a conceptual framework used in this paper for the analysis of the case of the Port of Gothenburg--the largest Scandinavian port, both in terms of number of visits and volume of cargo handled. The specific port is currently expanding its digital transformation by launching a platform during the second half of 2021 that will link digitally and coordinate the operations of all relevant stakeholders--shipping companies, freight forwarders, rail operators--at the port area. From the analysis, it becomes clear that the implementation of a wide portfolio of digital initiatives by the port under discussion has already resulted in the optimization of its operations and is strongly interrelated to its sustainable development. Important issues to be addressed in the near future that were identified by this research effort include the necessary cultural adaptation and training activities to ensure the right exploitation of these tools by the whole pool of the workforce.

The activity of the sensory organ in the eye structure of the teleost fish is essential as it plays an important role in regulating fish-feeding behaviours. Unfortunately, the above information of zebra-snout seahorse Hippocampus barbouri, an aquaculture species in Thailand, has not been described. In this study, the eye structure, together with the retinal structure of juvenile [5th and 20th day after birth (DAB)] and adult (35th DAB), H. barbouri reared in captivity was investigated. All DABs were carried out and histologically observed. Light microscopic level explored the external-lateral surface of eye structure of H. barbouri, which consisted of the external, middle, and inner layers, as similarly reported in other teleost species. A well-differentiated retinal and photoreceptor cell layer were observed at 35th DAB compared to that at other DABs. This feature might be adequate to support the base of the increased feeding activity of adult seahorse in captivity for further research.
Bishops, Kings and Leviathan: Nationalism and Integralism in Light of High Church Anglican Political Thought
Authors: Nolte Andrew
Published: December 2021

This article traces the political thought of high church Anglicans from 1580-1720. Beginning with Richard Hooker, Anglican political thought was shaped by the need to balance competing principles. For high church Anglicans, the monarchy was seen as the institution best positioned to defend this balance against what they saw as the twin threats of "Puritanism and popery." However, high churchmen also began to defend a high view of episcopacy even over against the power of the English government, introducing a tension between royal supremacy and high church Anglicanism with implications for both nationalist and integralist conceptions of the state. This culminated in the nonjurors—Anglican clergy and academics removed from their posts for refusing to swear oaths to William and Mary—defending episcopacy against both the new king and defenders of royal supremacy. The example of high church Anglicans demonstrates some perils of both nationalist and integralist approaches to politics for many religious forms of traditional conservatism.
Iranian Utopia: Suhrawardī and the Concept of ‘no-where’ in “The Chant of Gabriel’s Wings” and “The Crimson Intellect”
Authors: MOHAJERİ Faezeh
Published: December 2021

It is accepted that for the first time in 1516, Thomas More introduced the concepts of an ideal place in his Utopia; however, centuries before him in 1154 Shahāb al-Din al-Suhrawardī, a Persian philosopher, introduced the term Nā-kujā-ābād, which literally means utopia. This word was initially used in literature for defining an ideal society, which simultaneously bears the meaning of a non-existing or probably never-existed society. Accordingly, this article analyses the perennial Idealism in Suhrawardī’s Nā-kujā-ābād (no-where) by which he amalgamates the discourse of idealism with the perfect nature of human beings during the twelfth century. Nā-kujā-ābād is a prototypical term that illustrates the transcending world and portrays the ultimate perception of the living soul in utopia. The twofold essence of this term has always been at the center of the argument; a self-contradictory word, holding two opposite meanings at the same time: the spiritual world (Ālam-i Mesāl) and the material world (Ālam-i Nāsūt). This article aims to reconstruct Suhrawardī’s treatises through the textual analysis illuminating the interpretation of no-where through the utopian angle in treatises of The Chant of Gabriel’s Wings (Āwāz-i Par-i Jabraʾīl) and The Crimson Intellect (Aql-i Surkh) and finally concludes that Suhrawardī’s utopia is the true self of human beings apart from political and social issues.
TEACHING NATURE OF SCIENCE THROUGH CONCEPTUAL CHANGE APPROACH: CONCEPTUAL CHANGE TEXTS AND CONCEPT CARTOONS
Authors: Çil Emine
Published: December 2021

The study investigated the influence of conceptual change approach on elementary students’ views of certain aspects of nature of science (NOS). In this study, conditions of conceptual change were provided through the use of conceptual change texts and concept cartoons. In addition, this study compared the influence of the conceptual change approach to that of the explicit reflective inquiry-oriented and implicit instructional approaches in the teaching of NOS. The research was conducted with seventh-grade students (aged 12-13 years) at a school in Turkey’s Aegean region. A total of 69 students participated in the study. The students’ views of NOS were assessed using a questionnaire, (the Views of Nature of Science Elementary Level Scale) as pre-test and post-test in conjunction with data from semi-structured interviews. This study reveals that the best way to remedy the naïve views of students on NOS is a conceptual change framework.
Key words: conceptual change text, concept cartoon, explicit reflective approach, implicit approach, nature of science.
A centralidade do trabalho: estranhamento e contradições na atualidade
Authors: Da Silva Vargas Danilo
Published: December 2021

O artigo apresenta observações sobre como a centralidade do trabalho pode ser percebida na atualidade, buscando embasamento na teoria marxiana e discutindo fenômenos atuais que exemplifiquem tal condição. Buscamos desenvolver uma investigação teórica que permitisse ilustrar como é possível interpretar a centralidade do trabalho e como as contradições do trabalho se manifestam atualmente. Assim, o presente estudo analisa o papel do trabalho a partir de Marx e exemplifica suas contradições à luz de problemáticas atuais como a manutenção da lucratividade diante do drama da pandemia de Covid-19, as preocupações da OIT com o Trabalho Decente e a frustração de trabalhadores com as funções que exercem.

Com a chegada da Pandemia da COVID-19 ao Ceará, o Instituto Cearense de Educação de Surdos (ICES) viu-se em uma situação desafiadora para garantir o acesso e a permanência dos educandos por meio do ensino remoto. Este o artigo objetiva analisar os desafios no processo de escolarização dos estudantes surdos, do sexto ano, do ICES, no ensino remoto, no período da pandemia, em 2020. O percurso metodológico foi realizado por meio da pesquisa bibliográfica e do relato de experiência de umas das autoras do artigo, enquanto professora surda do ICES. Observou-se que para desenvolver uma nova forma de ensino que contribuísse para a formação da identidade, da cidadania e para a garantia do direito à educação aos surdos, foi necessária a parceria entre comunidade escolar, família e Estado. Ademais, espera-se que esta pesquisa possibilite novos caminhos a outros pesquisadores e docentes juntos aos alunos surdos.
Pobladores isleños frente a políticas de conservación: relaciones conflictivas en el Parque Nacional “Islas de Santa Fe” (Argentina)
Authors: Ferrero Brian , Massa Ernesto , Spiaggi Eduardo
Published: December 2021

El delta superior del río Paraná, es un área que viene experimentando profundas transformaciones desde inicios de la presente década. Desde hace más de diez años, el área está sujeta a diversas acciones que buscan su conservación, en este sentido se crearon programas como el PIECAS, Delta Sustentable, y se creó el Sitio Ramsar, y el Parque Nacional Islas de Santa Fe. La creación de este Parque Nacional, derivó en múltiples enfrentamientos entre la población histó- rica del área y el Parque, que se han prolongado en el tiempo. Dado que, en 2020, aún persisten dos familias en el área y se ha iniciado con las autoridades del Parque un proceso de diálogo, proponemos aquí un conjunto de alternativas productivas que contemplen políticas de conservación y que incluyan a los pobladores y su modo de vida.

Acerca de la resiliencia en organizaciones de alta confiabilidad en Argentina: un ensayo comparativo de casos
Authors: González Natalia L. , Cantero Javier H. , Díaz Daiana Valeria
Published: December 2021

Desde un abordaje organizacional, se analiza comparativamente la naturaleza y el nivel de resiliencia de tres sistemas riesgosos. Se trata de sistemas complejos e integrados, con una infraestructura cognitiva, objetivos múltiples y competencias organizacionales. El marco conceptual propuesto resulta de la fusión entre las teorías de la alta confiabilidad y de la resiliencia organizacional. El corpus empírico está integrado por el sistema ferroviario argentino, los equipos quirúrgicos de alta complejidad y una central nuclear. Finalmente, se presentan reflexiones sobre la diversidad del universo organizacional de alta confiabilidad y las discrepancias teórico-prácticas en los patrones de resiliencia, así como de la utilidad del desarrollo del corpus empírico local, tanto para robustecer la gestión como para fortalecer la agenda de investigación.

Authors: García María del Cármen
Published: December 2021

En la economia del conocimiento, se originan cambios en la naturaleza de los activos que generan valor para las empresas y se plantea la necesidad de proporcionar información sobre los activos intangibles autogenerados, aun no reflejados en la contabilidad tradicional. Hoy las empresas que brindan este tipo de información, muestran datos que consideran más importantes, pues no existe un consenso homogéneo, ni una normalización obligatoria al respecto.En esta investigacion de enfoque cualitativo exploratorio y descriptivo se concluye que esta información se debería seguir perfeccionando a futuro dentro de los Informes Integrados, manteniendo el carácter voluntario como información complementaria y no financiera e incorporando ciertas guias estandarizadas para cuantificar y medir el capital intelectual.
El duelo en el ámbito público
Authors: Carmona Gallego Diego
Published: December 2021

En la actualidad los femicidios han generado en nuestro país numerosas manifestaciones públicas de duelo. Las mismas han suscitado debates en la ciudadanía que ponen en tensión diferentes sentidos en torno al duelar. Para aproximarnos a algunas de estas cuestiones realizamos un recorrido pautado en tres ejes. En primer lugar, seleccionamos fragmentos de conversaciones en la red social Facebook, a la que hemos dado en llamar ágora virtual. Allí buscamos detectar los sentidos en tensión en torno al duelo: ¿privado o público? ¿íntimo o colectivo? A partir de estos retazos proponemos pensar las implicancias políticas y éticas de estas concepciones reponiendo una breve historización del duelo en la Atenas de la Antigua Grecia. Por último, formulamos una ontología de la vulnerabilidad e interdependencia y nos preguntamos por sus posibilidades de derivación en una ética del cuidado.

Límites de la libertad de cátedra en las instituciones de educación superior en México. Una forma de evitar el adoctrinamiento
Authors: Gutiérrez López Eduardo
Published: December 2021

La libertad de cátedra tiene dos dimensiones, una como derecho del docente y otra como garantía de las universidades. En ambas dimensiones existe el riesgo de que intereses ajenos propicien formas de adoctrinamiento que dañen el desarrollo de la educación superior. La primera dimensión se transgrede con prácticas docentes que conminen al estudiante hacia alguna creencia o ideología, y, la segunda, cuando la universidad se presta para sumarse a una agenda política ajena, con acciones de responsabilidad social y distanciándose de los objetivos académicos. Los límites para proteger ambas dimensiones son los principios axiológicos que puedan combatir el adoctrinamiento a través de su inserción a las políticas universitarias.

Published: December 2021

Introduction. The search for and development of new drugs capable of reducing the severity of neurological deficit in traumatic brain injury are a critical task for investigational pharmacology. Chromone-containing allylmorpholines are a new group of neuroprotective drug candidates that have been shown to inhibit acetylcholinesterase and butyrylcholinesterase, and block N-methyl-D-aspartate receptors in vitro.

Aim. This study aimed to evaluate the neuroprotective activity of the allylmorpholine derivative (E)-4-[3-(8-bromo-6-methyl-4-oxo-4H-chromen- 3-yl)-1-cyclohexylallyl]morpholin-4-ium chloride (33b) in vivo using a rat model of traumatic brain injury.

Materials and methods. Traumatic brain injury was induced using the controlled cortical impact model. The allylmorpholine derivative was administered intraperitoneally at 1, 10, or 50 mg × kg-1 b.w. at 1 h after trauma induction, and then daily for the next 6 d. The neurological deficit was assessed using the Limb Placing, Open Field, Elevated Plus Maze, Beam Walking, and Cylinder tests.

Results and discussion. At all doses administered, the allylmorpholine derivative had no positive effect on the motor function or exploratory behavior following traumatic brain injury. In the Elevated Plus Maze, 10 mg × kg-1 b.w. of the compound further suppressed exploratory behaviour in the injured animals, which appears to be consistent with its sedative properties observed previously in zebrafish.

Conclusion. Despite the previously described in vitro affinity of allylmorpholines towards several molecular targets crucial for the pathogenesis of brain trauma and posttraumatic functional recovery, an allylmorpholine derivative had no neuroprotective effect in a rat model of traumatic brain injury in this study. These results further emphasize the importance of in vivo evaluation of potential neuroprotective drug candidates.

Bu araştırmada 8.sınıf fen bilimleri öğretim programı ve 2019-2020 yıllarına ait liseye geçiş sınavı soruları SOLO taksonomisine göre analiz edilmesi amaçlanmıştır. Doküman inceleme yöntemi kullanılarak yapılan araştırmada sorular ve kazanımlar Fizik, Kimya, Yer Bilimleri ve Biyoloji alanlarına ayrılarak incelenmiştir. Alanlara ait kazanımların ve sınav sorularının SOLO ortalaması hesaplanmış ve karşılaştırılmıştır. Öğrencilerin bir üst öğrenime hazırlanmasında ve ölçülmesinde yetersizlik olduğu ve kazanımlarla soruların farklı bilişsel seviyelere eşit dağılmadığı tespit edilmiştir. Buna göre öğrencilerden edinmeleri beklenen kazanımlarla ölçülen kazanımların kısmen uyumlu olduğu söylenebilir. Bu durum bir üst öğrenime geçiş yeterliliğinin ölçülmesinde eksiklik olarak görülebilir. Sınavlarda tüm bilişsel seviyelere yönelik sorulara kazanımlarla uyumlu şekilde yer verilmesi önerilebilir.

Bu çalışma iki aşamadan oluşmaktadır. Birinci aşama Erzurum Anadolu Lisesi 9 C sınıfından oluşan öğrenci grubunu (37) içerirken; ikinci aşama Kazım Karabekir Eğitim Fakültesi Alman Dili Eğitimi ABD 1. Sınıf öğrencileri grubunu (70) içermektedir. Bu araştırmada nitel araştırma yöntemlerinden uygulama biçimleri deseni kullanılmıştır. Gözlem (sürekli), görüşme (yüz yüze ve uzaktan), denetleme, sorgulama ve verileri değerlendirme evreleri sürece dâhil edilmiştir. Çalışmada bu yanıyla, söz konusu grup öğrencilerinin konuşma yetersizliklerinin giderilmesi amaçlanmıştır. Her bir aşama 12 haftalık bir süreyi kapsamaktadır. Bu sayede yükseköğretim kurumları özelinde ve ortaöğretim lise özelinde öğrenci gruplarının aynı konu/sorun odaklı eylem alanına yönelik faaliyetlerinin, dil becerilerinin tanımlanması, aksaklıklarının belirlenmesi ve bunların üstesinden gelme stratejilerinin neler olması gerektiği noktasındaki ilkelerin belirlenmesine yöneliktir. Yanı sıra bu iki farklı grubun aynı sorun ağına bağlı olarak tutumlarının ve algı düzeylerinin belirlenmesiyle, bu sorunların giderilmesine yönelik önlemlerin ve ön çalışmaların hazırlanmasına dönük katkıların tespiti içinde, özgün öneme sahip stratejilerin oluşturulma imkânları elde edilmiştir. Ders saatlerindeki sınırlı program ile lise öğrenci grubunun aynı soruna yönelik çözüm odaklı eylemleri, fakülte öğrencilerine mukabil daha düşük seviyede gözlenmiştir. Nitel veri analizleriyle elde edilen bulguların sistematik bir gösterge çizelgesi üzerinden öğrencilerin konuşma becerilerine yönelik güçlüklerin ortadan kaldırılması amacıyla eylemsel olarak ileri sürülen, sorun giderici ilkeler on aşamada olumlu sonuç verirken; fakülte öğrenci grubunun bu sürece daha kısa sürede olumlu sonuç/ reaksiyon gösterdiği gözlenmiştir. Araştırmanın bulgu/sonuçlarına göre, uygulama sürecince her iki farklı gruptaki öğrencilerin sözlü iletişim becerileri çalışmalarında, konuşmaya yönelik güçlüklerin aşılmasında haftalara göre belirgin düzelmeler izlenmiştir. Diğer becerilerin de sürece dâhil edilmesiyle, konuşma etkinliklerinin grup öğrencilerin sözlü iletişim becerilerine önemli ölçüde olumlu etki ettiği sonucuna ulaşılmıştır.

Objetivos: O objetivo desse estudo foi descrever as vantagens e desvantagens da pasta CTZ para o tratamento endodôntico de dentes decíduos. Revisão de literatura: Os canais radiculares de dentes decíduos, têm características peculiares, que dificultam o acesso e a instrumentação, como: curvaturas acentuadas e altos índices de presença de canais acessórios. Os materiais obturadores utilizados na terapêutica endodôntica dos dentes decíduos precisam ser reabsorvíveis, antimicrobianos, possibilitar preenchimento e adesão às paredes dos canais radiculares, e devem ser de fácil remoção, características essas que possibilitam um não comprometimento para a dentição permanente futura da criança. A técnica de aplicação da pasta CTZ (cloranfenicol, tetraciclina e óxido de zinco eugenol) é considerada fácil, simples e pode ser realizada em uma única sessão, possui poder antibacteriano, promovendo a estabilização da reabsorção óssea e não causando sensibilidade tecidual. Além disso, ela não necessita de instrumentação prévia do canal radicular, independentemente do diagnóstico pulpar. Considerações finais: O tratamento endodôntico realizado na dentição decídua apresenta diversas limitações, como a sua anatomia e a dificuldade de execução de um tratamento invasivo em um paciente pediátrico. A utilização da pasta CTZ na terapêutica pulpar de dentes decíduos possibilita a manutenção dos dentes tratados endodonticamente, não oferecendo danos aos seus sucessores permanentes, por isso o seu uso se torna uma opção de tratamento pulpar na odontopediatria, entretanto, são necessários mais estudos que possam trabalhar a efetividade dessa pasta obturadora a longo prazo, ajudando a desmistificar tal acompanhamento.

The Aedes aegypti is the main vector of the transmission of diseases such as dengue, yellow fever, Chikungunya, and Zika. The agents used for the control of mosquito involve the use of synthetic compounds, which may cause toxicity and contamination environmental. Aiming to test the effectiveness of natural products, the aim of this study was to evaluate the larvicidal and repellent activity of extracts of Ateleia glazioveana Baill. (timbó) and essential oil of Ocimum basilicum L. (manjericão), against A. aegypti. The activities of hydroalcoholic (HEA) and dichloromethane (DEA) extracts from A. glazioveana against A. aegypti larvae were assessed after exposure for 24, 48, and 72 h, using water and Bacillus thuringiensis israelensis as negative and positive controls, respectively. For repellent evaluation, we investigated the sting attempts of A. aegypti in response to the application of HEA- and DEA-based body creams (5%), as well as an alcoholic spray based on the essential oil from O. basilicum. The repellency of these preparations was compared with negative (vehicle) and positive (DEET) controls. Although HEA showed no apparent larvicidal activity, DEA at concentrations of 150 to 500 mg/ml showed high larvicidal potential after 24 h, compared to the negative control group (p < 0.001). Moreover, the DEA-based cream and the alcoholic spray of O. basilicum based essential oil showed higher repellency compared with the vehicle (84.5% and 70.5%, respectively). Accordingly, it is possible to infer that extracts and preparations of A. glazioveana and O. basilicum exhibit larvicidal and repellent activity against A. aegypti.

Fenomena Dan Identitas Cadar: Memahami Cadar dalam Kajian Sejarah, Al-Qur’an, Hadis, dan Ijma’
Authors: Ilham Lailul
Published: December 2021

Cadar merupakan suatu realitas yang problematis dan menjadi topik pembicaraan yang hangat, khususnya dalam kontek Indonesia. Perselisihan tersebut tidak jauh berkutat pada tataran identitas cadar sebagai sebuah budaya atau syariat agama Islam. Kasus tersebut tidak selesai pada perselisihan ideologis bahkan dalam beberapa kasus sampai pada perselisihan secara sosial, seperti stigma masyarakat tentang cadar yang diidentifikasi dalam satu gerakan/kelompok Islam tertentu, cadar sebagai fanomena keislaman yang murni, cadar sebagai identitas budaya Arab, dan bahkan bagian dari identitas budaya agama lain (selain Islam). Kemudian kajian tentang cadar dalam berbagai perspektif menjadi urgen dilakukan sebagai upaya mempertegas status cadar kaitannya dalam identitas budaya dan agama. Sehingga akan ditemukan identitas sebenarnya dan menyelesaikan berbagai perselisihan yang secara umum diakibatkan oleh perbedaan cara pandang dan pemahaman terhadap cadar tersebut.
Konsep Ikhtilaf Dalam Perfektif Imam Syafi’i: Studi Islam Menyoal Perbedaan Sebagai Rahmat

Setiap manusia mempunyai hak dalam menyampaikan pendapat dalam hal apapun. Namun tidak dalam penentuan sebuah hukum syar‟i. Karena setiap pendapat mengenai hukum syar‟i perlu melalui sebuah proses dan memiliki kriteria khusus di dalamnya. Agar dapat ber-ijtihad dengan baik dan tepat maka harus berlandaskan pada Al-Qur‟an dan as-Sunnah. Setiap imam yang melakukan ijtihad tidak merasa dirinya paling baik, termasuk Imam Syafi‟i di mana beliau melarang muslim saat ini melakukan suatu taqlid. Para imam memiliki sudut pandang yang berbeda, yang menyebabkan terjadinya perbedaan pendapat dikalangan para imam. Hal ini dikarenakan perubahan zaman yang menyebabkan adanya suatu kasus atau permasalahan baru. Dalam hal ini kaum muslim memerlukan suatu kebenaran atas suatu kasus tersebut. Dan para imam ini yang berusaha semaksimal mungkin agar bisa  memberikan fatwa dari kasus atau permasalahan tersebut. Bukan hanya pada kalangan para imam, bahkan para imam bisa hidup harmonis dengan perbedaan yang ada. Berbeda dengan zaman sekarang, yang sering sekali melakukan perdebatan sengit guna mempertahankan pendapatnya sampai tidak menghiraukan akan larangan Allah untuk tidak bercerai berai dan hendaknya untuk terus bersatu.

Extracellular DNA (ecDNA) activates immune cells and is involved in the pathogenesis of diseases associated with inflammation such as sepsis, rheumatoid arthritis or metabolic syndrome. DNA can be cleaved by deoxyribonucleases (DNases), some of which are secreted out of cells. The aim of this experiment was to describe plasma DNase activity in relation to extracellular DNA in adult rats, to analyse potential sex differences and to prove whether they are related to endogenous testosterone. Adult Lewis rats (n=28) of both sexes were included in the experiment. Male rats were gonadectomized or sham-operated and compared to intact female rats. Plasma ecDNA and DNase activity were measured using fluorometry and single radial enzyme diffusion assay, respectively. Concentrations of nuclear ecDNA and mitochondrial ecDNA were determined using real-time PCR. Females had 60% higher plasma DNase activity than males (p=0.03). Gonadectomy did not affect plasma DNase in males. Neither the concentration of total ecDNA, nor nuclear or mitochondrial DNA in plasma differed between the groups. No significant correlations between DNase and ecDNA were found. From previous studies on mice, it was expected, that male rats will have higher DNase activity. In contrast, our study in rats showed the opposite sex difference. This sex difference seems not to be caused by endogenous testosterone. Interestingly, no sex differences were observed in plasma ecDNA suggesting a complex or missing association between plasma ecDNA and DNase. The observed sex difference in plasma DNase should be taken into account in animal models of ecDNA-associated diseases.

Published: December 2021

Mass-spectrometric thermal decomposition experiments with submicron films of neat polymethylmethacrylate (PMMA), and PMMA-fullerene composite (PMMA-C60) after UV irradiation are discussed. The experiment registers thermal desorption mass spectra (TDMS), that is the monomer desorption rate versus time upon gradual heating the PMMA films in a given heating regime. The spectra provide information on the amount of the monomer desorbed at different decomposition stages upon heating the given amount of film material as well as on the spectral shape changes. It is shown that both amount of monomer and the TDMS spectral shape are sensitive to the presence of fullerene and UV irradiation. The experimental results are discussed in terms of quantum chemical models of binding. The DFT/B3LYP-D3/def2/J RIJCOSX level of theory was used. The MMA-C60 structures which can yield different amounts of monomer have been compared.

The rivers flow on the island of Borneo have had a significant function for human life since a long time ago. The river has had a role in the dynamics of civilization and environmental evolution in human life until now. With the construction of road infrastructure, the significance of rivers for riverside communities has also changed. This study sees how Ngaju people interpret the river in a living space that changes with development. The research was conducted in two villages which show the characteristics of different locations, society, and development rates. The villages are Talingke village on the bank of the Katingan River and Pangi Village on the bank of the Kahayan River. Data collection were through observation, interviews, and literature study. The study shows that the characteristics of the river area, the community, and the development rates affect the community in interpreting the river. On the one hand, Pangi people start to leave activities in the river, but they still hold the values of the river in their lives. On the other hand, Talingke’s people still focus their activities on the river but no longer have river values in their lives.
Cow’s milk contamination with 137Cs depending on quality and supply of pasturage
Authors: Borshchenko V. , Slavov V.
Published: December 2021

The results of studies on transferring of 137Cs to cow’s milk during the grazing season on two pastures in Narodychi district, Zhytomyr region, which differ in 137Cs ground deposition and intensity accumulation of radionuclide by herbage. It has been proposed a specific methodical approach for interpreting the radiological consequences of the pastures use by grazing cows. This approach is that the contamination of cow’s milk should be linked to the quality and supply of pasture forage. Research has found that in most cases reducing the quality and supply of pasture grass the activity of 137Cs in milk decreases, although this fact is less obvious to hospitals with severe particle size and high 137Cs ground deposition. This can be explained by 137Cs of the soil origin on contamination of cow’s milk.
