Authors: Asiah Nurul
Published: March 2021

Telur asin merupakan salah satu makanan tradisional Indonesia yang mudah mengalami penurunan mutu selama proses penyimpanan. Salah satu metode untuk mempertahankan mutu dan memperpanjang umur simpan adalah dengan penyimpanan suhu rendah. Penelitian ini dilakukan dengan tujuan mengetahui umur simpan dan penurunan mutu telur asin presto selama penyimpanan suhu rendah. Penelitian ini dilakukan dengan beberapa tahap. Tahap pertama adalah pemeraman telur itik selama 7 hari dengan menggunakan adonan garam dengan konsentrasi garam sebanyak 22,5% terdiri dari campuran serbuk batu bata halus, abu gosok, garam dan air dengan perbandingan 15:6:9:1 (b/b). Tahap kedua adalah pematangan dengan presto selama 20 menit. Proses pematangan dengan presto dipilih karena lebih cepat. Tahap ketiga adalah prediksi umur simpan telur asin dengan metode survival analysis. Tahap keempat adalah pengujian mutu (kadar air, pH dan warna) awal dan akhir telur asin. Hasil menunjukkan bahwa umur simpan telur asin presto pada penyimpanan suhu 4°C adalah 8 hari. Kadar air merupakan parameter mutu yang mengalami penurunan mutu paling besar, yaitu 7,13 % pada putih telur dan 15,46% pada kuning telur. Sedangkan pH dan warna hanya mengalami perubahan nilai sebesar ± 2 digit.  ABSTRACT: Salted egg is one of Indonesia's traditional foods that is easily degraded during storage. One method to maintain the quality and extend shelf life is store in low temperatures. This research was conducted with the aim of knowing the shelf life and quality change of presto salted egg during low temperature storage. This research was conducted in several stages. The first stage was ripening of duck eggs for 7 days using salt mixture with salt concentration of 22,5% consist of fine brick powder, rubbing ash, salt and water with ratio of 15:6:9:1 (w/w). The second stage was cooking with presto for 20 minutes. The cooking in presto pan was chosen because faster prosess. The third stage was shelf life prediction of salted eggs with a survival analysis method. The fourth step was analyzing the quality change of salted egg (water content, pH and color) at the beginning and end of storage. The results showed that predicted shelf life of salted eggs at a storage temperature of 4°C was 8 days. Water content was the highest quality parameter that changes ie 7,13% in egg whites and 15,46% in egg yolks. While the pH and color value only changes ± 2 digits.

Published: March 2021

This study aims to understand the association among sport participation, substance use and mental health of adolescent athletes within a diverse urban youth population. Data included a convenience sample of predominantly Black and Hispanic youth (85.7%) ages 14 to 18 years, who were Mount Sinai Adolescent Health Center (MSAHC) patients who presented for an annual physical exam or pre-participation exam (PPE) and were cleared for high school sport(s) participation. During the encounter, participants self-reported their use of tobacco, alcohol, and marijuana on a 6-point frequency scale, dichotomized to indicate use in the past 30 days. Anxiety and depression were assessed using two self-reported questions. Demographic data (e.g. ethnicity, gender, age) and whether participants had a current mental health provider were also extracted from the Electronic Medical Record (EMR). Results from multivariate logistic regression analyses showed adolescents with one year of sport participation had significantly lower odds of alcohol use in the past 30 days (OR=0.22, 95%CI= [0.12,0.41]) compared to individuals who did not participate in sport(s). Adolescents with two or more years of sport participation had significantly lower odds of alcohol (OR=0.46, 95%CI= [0.23,0.93]) and marijuana use (OR=0.10, 95%CI= [0.01,0.72]) in the past 30 days compared to individuals who did not participate in sport(s). Adolescents with one year of sport participation had lower odds of reported depression (OR=0.56, 95%CI= [0.33,0.94]) compared to individuals who did not participate in sport(s). Adolescents with two or more years of sport participation had significantly lower odds of reported depression (OR=0.35, 95%CI= [0.16,0.75]) and anxiety (OR=0.36, 95%CI= [0.15,0.86]) compared to individuals with no sport participation. These effects were found after adjusting for whether they were currently engaged with a mental health provider. Results of this study suggest that engagement in organized sport(s) may have protective effects against substance use, depression and anxiety. Additionally, the PPE could be used as an opportunity to promote engagement in extracurricular activities in addition to organized sports, to maximize the opportunity for adolescents to experience these benefits.

Allergic diseases are increasingly becoming a global epidemic and pose a considerable and growing public health burden. Allergy is a systemic T2-dependent inflammatory reaction to an allergen that results from a complex interaction between genetic and environmental factors. Allergic diseases occur through a T2-dependent type of allergic reaction, some of them, in particular atopic dermatitis (AD) and asthma, develop involving different types of hypersensitivity or their combination and require revision of allergy diagnostics. Atopy patch test (APT) can be informative in establishing a role of cell-mediated hypersensitivity in pathogenesis of allergic diseases.
The review presents the recent data on the significance of APT in the diagnostics of skin and respiratory allergies.

Authors: Levina Daria M. , Korsunskiy Ilya A. , Munblit Daniel B.
Published: March 2021

Food allergy is one of the most prevalent allergic conditions, causing reduction in patient quality of life. It is linked with high levels of anxiety due to potential life-threatening reactions, and high economic burden for a healthcare system. Food allergy affects approximately 5 to 10% of children around the world. In Russian Federation the diagnosis of food allergy is primarily based on clinical history, laboratory test results, examination and elimination of suspected food. Meanwhile oral food challenge (OFC) is considered a gold standard of food allergy diagnosis by most of professional bodies nationally and internationally. OFC is a diagnostic procedure involving administration of a causative allergen in gradually increasing amount under a close medical supervision. The method is safe, highly specific and sensitive and is widely used around the world for more than 45 years. The main goals of OFC include food allergy diagnosis and presence of tolerance evaluation, which may result in diet expansion. OFC may also help establishing both, reaction severity and dose needed to elicit reaction, which may further assist with alleviation of patients anxiety. In this paper we discuss existing approaches to the diagnosis of food allergy in Russian Federation and review available recommendations on OFC outlined in international guidelines.

Published: March 2021

Education is an important input for empowering people with skill and knowledge and giving them access to productive employment in future. It is an important input as well as output indicators influencing other development indicators of social sector such as health, nutritional status, income, family welfare and others. Both primary and secondary education deserves the highest priority for increasing the competence of the average worker and increasing National productivity. As the provision of universal elementary education is crucial for spreading mass literacy, the provision for secondary education is significant for economic development, modernising social sector and for effective working of democratic institutions. Secondary education serves as a link between the elementary and higher education and plays a very important role in this respect. Since universalisation of elementary education has become a constitutional mandate, it is absolutely essential to push this vision forward to move towards universalisation of secondary education which is already been achieved in a large number of developed countries and several developing countries. The recent focus on secondary education was generated by the 2005 Central Advisory Board of Education Report (2005) and the Rastriya Madhyamik Sikhya Abhiyan (RMSA) initiated in 2009-10 to universalize secondary education by making quality education available, accessible and affordable to all children within the age group of 14-18 years with strong focus on the elements of gender equity and justice. This paper studies the access to an equity and quality in primary and higher secondary education classes (IX-XII) in Odisha and examine some idea for improvements in each.

Based on observations of beavers in anthropogenic landscapes, the study of methods of their maintenance and feeding in the zoo assumptions are made about the broad ecological plasticity of the species. This is achieved by both morphophysiological adaptations and behavioral adaptations, which are associated with the processes of synanthropization and domestication. This is also associated with the processes of rapid restoration of the number of beavers and their range in places of former extermination. The river beaver is a promising object of zooculture, including breeding in artificial conditions.
The relative importance of training volume and coach autonomy support for preventing youth swimming attrition
Authors: Larson Heather , Young Bradley , McHugh Tara-Leigh , Rodgers Wendy
Published: March 2021

There are hypothesized associations between high training volume in youth sport and negative psychological and behavioral outcomes such as decreased enjoyment, and increased burnout and dropout. Autonomy support, however, is associated with positive motivational and behavioral outcomes. The purpose of this study was to concurrently explore the relationships of training volume and perceived coach autonomy support with enjoyment, commitment, burnout symptoms, and dropout from swimming. Survey data were collected from 265 swimmers (Mage = 13.78 ± 1.60) representing more than 50 clubs across Canada. Their parents provided training volume data. Several months later, at the start of the next swimming season, a follow-up survey identified which swimmers dropped out. Structural equation modeling did not show a significant relationship between training volume and enjoyment, but there was a significant pathway from autonomy support to enjoyment, which predominantly predicted functional commitment. Obligatory and functional commitment differentially predicted burnout and intentions to continue swimming. Swimmers who dropped out had significantly lower training volume, enjoyment, functional commitment, and intentions to continue swimming, and higher sport devaluation, compared to those who continued swimming in the following season. Perceptions of an enjoyable, autonomy-supportive training context in adolescent swimming seem to have greater associations than training volume with several psychological and behavioral outcomes, including burnout symptoms and dropout.

Problemas fechados e abertos e que abordam temas de relevância social na Matemática e suas tecnologias no Ensino Médio
Authors: Figueiredo Fabiane Fischer
Published: March 2021

Neste artigo busca-se discutir e compreender as potencialidades e/ou limitações metodológicas e educacionais de enunciados de problemas produzidos com o uso de tecnologias digitais, para a proposta de (re)formulação e resolução na área da Matemática e suas Tecnologias, no Ensino Médio, de acordo com a “Base Nacional Comum Curricular” (BNCC) (Brasil, 2018). Para tanto, escolheu-se dois enunciados de problemas, um fechado e outro aberto, que tratam de temas de relevância social ligados à macroárea temática Economia, cujos designs foram realizados por Figueiredo (2017), com o uso de tecnologias digitais, e poderiam ser, também, propostos em práticas pedagógicas, no Ensino Médio, e contribuir para aprendizagem matemática, associada aos temas abordados e uso de tecnologias digitais. A partir da análise e reflexão acerca desses enunciados, foi possível reconhecer que, por terem sido produzidos por meio do design de problemas com o uso de tecnologias digitais, foram atribuídas características e aspectos, de acordo com o tipo de problema pretendido, que, mesmo possuindo algumas potencialidades semelhantes para a (re)formulação e resolução com o uso de tecnologias digitais, os abertos possuem outras, em termos metodológicos e educacionais, por serem pré-determinados, entre elas a articulação entre um tema e outras temáticas, o trabalho interdisciplinar e a tomada de decisões, de forma mais pessoal e autônoma.
Novos conteúdos e novas habilidades para a área de Matemática e suas Tecnologias

No âmbito escolar, entender de políticas públicas torna-se obrigatório, pois constantemente gestores e educadores são surpreendidos por políticas educacionais que regem toda a estrutura escolar. Com isso, são necessárias reflexões e discussões sobre a construção, abordagem e implementação de tais políticas nas escolas públicas. Nesse cenário, um grupo de professores universitários, pesquisadores e professores em atuação na educação básica está elaborando um material didático destinado ao ensino e aprendizagem de matemática, que esteja em consonância com a Base Nacional Comum Curricular (BNCC) e o Novo Ensino Médio (NEM). Assim, o objetivo desse texto é apresentar reflexões realizadas ao elaborar dois capítulos desse material e discutir alguns dos princípios norteadores e características gerais de dois capítulos do referido material.  Um dos capítulos é destinado ao ensino e aprendizagem de projeções cartográficas e o outro a introdução ao pensamento computacional no ensino médio. Quanto ao pensamento computacional, destaca-se que da forma como está proposto neste momento, a BNCC privilegiou o aspecto algorítmico desse pensamento nas habilidades descritas e limitou a sua presença na área de Matemática e suas Tecnologias. Observa-se que o mesmo ocorre com o ensino de Projeções Cartográficas, que conforme a BNCC deve ser responsabilidade dos professores de Matemática. Visto que tanto a base quanto o NEM são realidades impostas, as reflexões apontadas no texto discutem as implicações da inclusão desses objetos do conhecimento no encargo da disciplina de Matemática. Além disso, apresentam-se atividades para que os professores de matemática consigam dar conta dessas novas demandas.

Promulgada a Lei nº 13.415/2017 que altera a legislação anterior e institui a Política de Fomento à Implementação de Escolas de Ensino Médio em Tempo Integral torna-se necessário que a comunidade acadêmica mantenha as discussões e reflexões a respeito da temática. A polêmica ao redor do Novo Ensino Médio não se desfaz com a promulgação da lei, mas se intensifica pela necessidade de concretização e implementação deste novo formato. Em especial no que tange à Matemática como área de conhecimento obrigatória na formação dos jovens que cursam o Ensino Médio, se exige da comunidade de educadores matemáticos o conhecimento e a reflexão sobre a legislação e suas possíveis consequências. Este artigo, elaborado a partir de pesquisas documental e bibliográfica, tem o objetivo de destacar pontos para esta reflexão, bem como possibilidades e desafios sobre o Novo Ensino Médio na comunidade de educadores matemáticos. Para isso, retoma a origem desta discussão e o posicionamento de autores da Educação e da Educação Matemática. Considera-se a necessidade do debate contínuo para superar os desafios apresentados pelas atuais condições econômicas, políticas, sociais, bem como daquelas instituídas pela lei, em prol da concretização de um novo Ensino Médio que efetivamente contribua com a formação humana de uma nova geração.

De uma Antropologia do Reconhecimento para Ética Ambiental em Axel Honneth
Authors: Cichelero César Augusto
Published: March 2021

O trabalho apresenta como temática a relação entre a antropologia aristotélica e a categoria reconhecimento honnethiana, com o intuito de a partir dessa construção conceber uma ética ambiental a partir do complexo institucional na sociedade moderna. Como contraponto se realiza uma crítica da concepção humana individualista encontrada em autores como Maquiavel e Hobbes, para então relacionar o reconhecimento em Honneth e uma antropologia relacionada com Aristóteles. Honneth afirma que o motor da sociedade é o conflito, a luta pelo reconhecimento. Como as identidades são construídas neste conflito, é o reconhecimento que assume uma forma de restaurar as relações distorcidas entre os sujeitos evitando as patologias sociais. O reconhecimento acontece três esferas distintas, amor, direito e solidariedade, e, para Honneth ele é uma questão ética, ligado à ideia de realização plena de uma boa vida. O método utilizado foi a analítico, por meio da revisão das obras referenciadas.
A Atuação das Organizações não Governamentais (ONG`s) na Proteção do Meio Ambiente na Amazônia
Authors: Britto Freire Araujo Daniel
Published: March 2021

O presente estudo versa sobre a atuação das organizações não governamentais na proteção do meio ambiente na Amazônia. Com o advento da Constituição da República em 1988, o meio ambiente ecologicamente equilibrado foi alçado à condição de verdadeiro direito fundamental de 3ª dimensão, vinculado, assim, ao valor fraternidade e solidariedade. O dever de efetivar tal direito fundamental é de todos: Estado, pessoas jurídicas de direito privado, coletividade e cidadãos individualmente considerados. Neste cenário, as organizações não governamentais, entidades privadas que perseguem uma finalidade de interesse público, ainda que pouco numerosas na Região Norte do Brasil, desempenham um importante papel na preservação da Amazônia, seja com a realização de pesquisas, seja com atuação sobre aspectos sociais que impactam no meio ambiente desse importante bioma.
Mathematisches im Corpus der Goethezeichnungen
Authors: Bauke Dieter
Published: March 2021

Goethes Beschäftigung mit mathematischen Fragestellungen oder der Mathe¬matik finden wir nicht nur in seinen Texten. Auch in seinem zeichnerischen Werk finden wir, bisher fast unbeachtet, Beispiele für die Auseinandersetzung mit mathematischen Problemen (hier unter Ausschluss der Optik und vieler archi¬tektonischer Fragen). Einige Zeichnungen sind auch von Bekannten Goerthes, wie Riemer oder Werneburg, sie sind Diskussionsgrundlage zu mathematischen Fragestellungen. Insgesamt finden wir u. a. ein magisches Quadrat, verschie¬denste geometrische Skizzen, Fünfeckkonstruktionen, architektonische Fra¬gestellungen, Winkeldreiteilung und den Satz des Pythagoras, aber auch ein Barogramm, die Ebbe-Flut-Theorie nach Galilei, die mathematisch fundierte Darstellung geologischer Massen. Die Konstruktion von Ellipsen oder Spiralen ist durch Kreisbögen angenähert (Korbbogenkonstruktionen). Überraschend ist, dass Goethe die Kegelschnittherleitung (Schnitt eines Kreiskegels) kannte. Besonders interessant ist eine Skizze über die Verhältnisse von Umfang und Diameter bei Kreis und Quadrat. Nicht alle Skizzen können eindeutig identifiziert werden, hier ist weitere interdisziplinäre Forschung nötig.
