Digital Architecture of Control: North Korea’s Use of Technology to Consolidate Totalitarian Governance
Authors: Baek Jieun
Published: January 2025

North Korea’s increasing technological sophistication is reshaping its approach to totalitarian governance. This article examines how the regime employs digital tools to consolidate state power through enhanced surveillance, regulatory frameworks, and ideological programming. It argues that the strategic integration of technology is central to North Korea’s efforts to reinforce its totalitarian system, deter foreign influence, and suppress internal dissent. By analyzing both deterrent measures (including advanced surveillance technologies and restrictive laws) and offensive measures (including the proliferation of state-approved media), this article demonstrates how these efforts are shaping citizen behavior to align more closely with state expectations. Additionally, the article explores instances of quiet resistance, where citizens subvert state control through the very technologies designed to monitor them. The findings contribute to broader discussions on authoritarianism and the role of digital governance in sustaining repressive regimes, offering insights for policymakers seeking to counter these developments.
Contiendas por el control territorial y pluralidad de reglas de dominación en el proceso de formación del Estado colombiano
Authors: Díaz Londoño Jorge Andrés
Published: January 2025

The purpose of this article is to carry out a historical and comparative analysis of how the disputes over land ownership and territorial control in the 1980s influenced the forms of regulation of social relations and community life that developed in the territories of Llanos del Yarí, Medio and Bajo Caguán, Carare and Puerto Boyacá. To answer this question, I returned to the theoretical contributions of the relational sociology of the state and comparative historical sociology, which allowed me to understand the processes of configuration of social arrangements and formation of the state as historical constructions of each society that are forged within the framework of power relations (Brachet-Márquez 2012; Migdal 2011). Methodologically, I developed a comparative design of four case studies, which had a broad territorial impact during the 1980s because they reflected different forms of domination and challenge to established powers, by peasant organizations that promoted significant experiences of community resistance in the midst of war and by armed groups that consolidated territorial domains, in a context where the State also promoted strategies of social regulation. I highlight the potential for learning and explanation that the comparison of these case studies generates.

The impact of group coaching on the self-efficacy, test anxiety and perceived stress in male adolescents
Authors: Cranston Jack , Budd Mary-Jane
Published: January 2025

One-to-one coaching interventions have had a demonstrably positive impact on the psychological wellbeing of young people but are beyond the resources of many schools. By contrast, group coaching has received little investigation and may be more feasible and offer similar benefits. This study sought to examine the effectiveness of group coaching to decrease test anxiety and perceived stress and increase self-efficacy amongst male students attending an English secondary school. In a quasi-experimental between-participant design, 32 male students between 16 and 18 years of age were allocated to a group coaching programme (n=16) or a wait-list control group (n=16) based on existing class membership. The six-week group coaching programme was structured around the GROW coaching model and was facilitated by a teacher-researcher trained in coaching psychology techniques. ANCOVA analyses indicate that group coaching had no statistically significant effect on self-efficacy or perceived stress, despite improved post-intervention mean scale scores for both measures. The coaching group experienced a significant increase in test anxiety whereas the control group demonstrated improved post-intervention scores against this measure. Findings did not attest to a significantly positive impact for group coaching. Further research is recommended to determine the potentially detrimental effects of group coaching against certain measures and which wellbeing measures may be enhanced in adolescents as effectively as using traditional one-to-one coaching.
Gene Identification for Phototropin-dependent Photoprotection in Chlamydomonas Reinhardtii
Authors: Pang Anthony , Su Che , Peng Yunqi
Published: January 2025

Photosynthetic organisms convert solar energy into chemical energy through photosynthesis, generating carbohydrates and lipids that are valuable for biofuels. Algae, renowned for their rapid growth and efficiency, have developed mechanisms to adapt to varying light conditions, ensuring their survival and prosperity. Among these mechanisms, photoprotection strategies such as Non-Photochemical Quenching (NPQ) enhance their tolerance to high light intensities. Excessive light intensity can cause detrimental overexcitation of the photosystems. In Chlamydomonas, one of the proteins, LHCSR3, provides a quick protective response known as energy-dependent quenching (qE), the fastest and most important component of NPQ. Deletion of LHCSR3 leads to cell death under high light conditions. Recent research has shown that blue light, perceived by phototropin (PHOT), mediates the photoprotection of the photosynthetic machinery under high light conditions in Chlamydomonas reinhardtii. Deletion of PHOT leads to compromised expression of LHCSR3 under high light conditions, therefore leading to cell death. However, the downstream signaling components of the PHOT-LHCSR3 pathway remain largely undiscovered. The objective of this project was to identify and characterize new actors involved in PHOT-dependent photoprotection in Chlamydomonas. Using forward genetics and omics analysis, we built a mutant library that could survive under high light intensity in a phot background. We also identified 8 putative PHOT-dependent photoprotection downstream signaling components. Overall, this project brings new insights into the acclimation of photosynthesis to high light. The mutant library could be further used for additional research. Furthermore, understanding photoprotection will not only help increase microalgae biofuel production productivity but could also provide new insights into the genetic engineering of crops for high light resistance.

Axolotls, environmentally conscious mayors and watermills: Didactic proposals for raising awareness on water conservation through pedagogical translation
Authors: Zimányi Krisztina , Vargas Montiel Denisse Alejandra , Pereira Carneiro Lydia , Pitte Robin Dominique Jean , Ayala Ciprés Renata , Escamilla García Valeria Tinúviel
Published: January 2025

The present article explores the possibilities of integrating Sustainable Development Goal (SDG) #6 (Clean water and sanitation) in the content of materials designed for Spanish as a second or foreign language (S2/FL) learners in a Mexican context. The idea arose from the recent severe droughts in the country that affected water consumption in certain cities. For immersion students studying S2/FL in Mexico, this became a reality rarely discussed in the classroom. In addition, the use of pedagogical translation is proposed to take advantage of the opportunities offered by the learners’ already existing linguistics skills. Considering the particularities of the context where the project was developed, the material design stage was preceded by two smaller enquiries into the perception of Mexico and Mexican culture abroad as well as the country’s representation in existing S2/FL materials. One specific point of interest was if everyday realities where the lack of water received mention in the foreign press and / or if S2/FL textbooks. The resulting activities propose to cover these rather complex topics through a ludic perspective that can be replicated and adapted to a variety of contexts and any one of the SDG.

Elecciones de cambio y desmovilización. La participación electoral.
Authors:   Universidad de Granada, Cazorla Martín Ángel , Ortega Villodres Carmen ,   Universidad de Granada
Published: January 2025

En el presente capítulo se analizan las bases sociales y políticas de la movilización electoral registrada en las consultas generales de 2015 y 2016. Estas se caracterizaron por arrojar unos muy bajos niveles de participación electoral, hasta tal punto que la afluencia a las urnas en junio de 2016 marca el nivel más bajo de participación ciudadana en este tipo de convocatorias desde el año 1977. De igual modo, estas han sido las segundas y terceras convocatorias desde que la economía española entró en recesión a finales de 2008, hecho que, en opinión de muchos observadores y analistas políticos, afectó directamente a la confianza política, convirtiéndose en una cada vez más importante crisis política e institucional. Esta situación mantenida de crisis económica, política y social ha tenido como consecuencia un aumento considerable de los niveles de desafección y de descontento político, que aunque no han afectado a la legitimidad del sistema democrático, sí que han erosionado profundamente sus bases.
Economic Burden of Endometriosis: A Systematic Review and Meta-Analysis
Authors: Yuspa Ripandi
Published: January 2025

Introduction: Endometriosis, marked by uterine-like tissue growth outside the uterus, causes severe pelvic pain and infertility. Delayed diagnosis contributes to its significant global economic burden, especially in Europe and the USA. Despite treatment advances, managing endometriosis remains challenging. Comprehensive strategies are urgently needed to reduce its economic impact and improve patient outcomes.
Material and Methods: We searched for English-language full-text literature from PubMed, Cochrane, Wiley Library, and ScienceDirect databases from January 2013 to January 2024. Total of 951 studies were identified, and 14 studies were included, providing comprehensive data on the economic burden of endometriosis, including direct healthcare costs and productivity losses.
Results: The economic burden of endometriosis, based on 14 studies, is substantial, reflecting both direct healthcare costs and productivity losses. Average annual costs per woman ranged from EUR 8,768 in Sweden to Int $16,970-$20,898 in Australia. Non-surgical treatments in the USA were more cost-effective than surgery, costing $100,000 per QALY. In the UK, the LNG-IUS was the most expensive treatment at £650.94. Costs in China for various therapies ranged up to $10,728 with differing ICERs.
Conclusion: These findings underscore the significant economic impact and the need for cost-effective management strategies: costs and productivity losses. Effective management strategies are essential to mitigate these costs.

Introdução: Osteossarcoma é neoplasia maligna agressiva, de origem mesenquimal, encontrado frequentemente em regiões metafisárias de ossos longos. A sobrevida geral em 5 anos é de aproximadamente 65%, sendo as metástases pulmonares as principais causas de óbito. Os biomarcadores ou marcadores tumorais podem ser capazes de prever o comportamento futuro de neoplasia maligna.
Objetivo: Investigar a expressão imunoistoquímica das proteínas β-catenina, CDX2 e c-MYC em amostras de osteossarcoma e correlacionar a expressão das proteínas β-catenina, CDX2 e c-MYC dos tecidos com a idade ao diagnóstico, tempo de sobrevida e doença metastática.
Método: Estudo observacional, longitudinal, prospectivo histórico tendo sido selecionados 64 casos de osteossarcoma realizando imunoistoquímica para os marcadores β-catenina, CDX2 e c-MYC em 28 amostras. Dados clínicos foram coletados e tabulados. Através da técnica TMA (tissue microarray) os tecidos foram submetidos à imunoistoquímica pela técnica de peroxidase. As informações clínicoepidemiológicas foram cruzadas com o resultado obtido pela imunomarcação e feita análise estatística.
Resultado: Dos pacientes 14 eram mulheres e 14 homens. Evoluíram com metástases 50%. Cinco de 27 (18,5%) com osteossarcoma de alto grau positivaram para β-catenina; destes, 80% evoluíram com metástase e tinham no máximo 20 anos de idade. Não houve marcação imunoistoquímica positiva para CDX2 e a sobrevida para pacientes com marcação negativa foi de 48%. A expressão do c-MYC foi associada à mortalidade de 50% e não foi detectada em pacientes na faixa etária de 5-20 anos de idade. A sobrevida em 5 anos foi em 46,7%. O tempo de seguimento máximo foi de 133 meses. A disseminação metastática pulmonar ocorreu em 92,9% dos 14 que evoluíram com metástases. A localização tumoral foi de 75% em MMII, 21,4% em MMSS e um caso em pelve.

As tecnologias de engenharia biomédica têm desempenhado um papel cada vez mais relevante no cuidado de pacientes com insuficiência cardíaca, uma das principais causas de mortalidade no mundo. Nesse contexto, a insuficiência cardíaca, devido à sua alta prevalência e impacto na saúde pública, exige soluções que vão além dos tratamentos convencionais. Os desafios associados ao diagnóstico precoce, ao controle da progressão da doença e ao manejo das comorbidades tornam imprescindível a adoção de tecnologias avançadas. Ainda, a incorporação de tecnologias biomédicas no tratamento da insuficiência cardíaca representa uma oportunidade de transformar o paradigma do cuidado, passando de intervenções reativas para uma abordagem preditiva e preventiva. Desta forma, o presente trabalho tem como objetivo investigar o impacto das tecnologias de engenharia biomédica no cuidado de pacientes com insuficiência cardíaca, analisando como dispositivos e sistemas inovadores têm contribuído para melhorar os desfechos clínicos, reduzir hospitalizações e oferecer uma abordagem mais personalizada e eficiente. Conclui-se que, dispositivos como marcapassos implantáveis, desfibriladores, e sistemas de monitoramento remoto têm permitido um acompanhamento contínuo e mais preciso da saúde dos pacientes. Esses avanços não apenas facilitam o diagnóstico precoce de complicações, mas também proporcionam intervenções mais rápidas e personalizadas, resultando em melhores desfechos clínicos. Por fim, apesar dos avanços significativos proporcionados pelas tecnologias biomédicas, ainda existem desafios a serem superados, como o custo elevado dos dispositivos e a necessidade de infraestrutura adequada para o monitoramento remoto.

Published: January 2025

Este artigo, consiste em um recorte da pesquisa de mestrado em ciências que está sendo desenvolvido no Programa de Pós-graduação em Enfermagem da Universidade Federal de Pelotas, e objetiva a aplicação da teoria de Cida Bento “o pacto da branquitude”, para estruturar o pensamento crítico decolonial quanto ao epistemicídio que ainda permeia os espaços formativos de ensino superior. Para isso, a teoria foi aplicada sob estudos indexados no Periódicos da CAPES, coletados através de revisão integrativa de Mendes; Silveira; Galvão (2008), no mês de outubro de 2024. Os resultados apontam que o pacto da braquitude e o epistemicidio vem exercendo uma força contraria a permanência dos estudantes negros no ensino superior. Tão logo conclui-se que abordar a evasão dos estudantes negros relacionando a estas teorias é necessário, não limitando-se a estudos de revisão, mas também outras abordagens que possam ouvir in loco esse grupo estudantil e discutir a partir desta perspectiva.

Published: January 2025

A construção civil vem enfrentando problemas ambientais devido ao elevado consumo de recursos naturais e a geração de resíduos. Com o contínuo crescimento do setor surgem desafios como a necessidade de desenvolver novos materiais e processos construtivos. Nesse cenário, este estudo buscou investigar o uso do pó obtido da mucilagem extraída do cacto Mandacaru como aditivo na argamassa de cimento, avaliando os efeitos desse componente nas propriedades do material em seus estados fresco e endurecido. Para isso, testes foram realizados para analisar aspectos como consistência, capacidade de retenção de água e resistência mecânica. Para a realização dos testes, foram preparadas amostras com diferentes teores de pó de Mandacaru, nomeadas como R (sem aditivo), A com 0,0125%, B com 0,1%, C com 0,5%, e D com 1,0%. Os resultados mostraram que o pó de Mandacaru tem potencial para agir como plastificante na argamassa de cimento, além de contribuir para a redução da absorção de água sem comprometer a resistência mecânica do material. A análise por Difração de Raios X mostrou que nas amostras aditivadas com pó de Mandacaru não houve a formação de estruturas cristalinas distintas das fases de hidratação do cimento, apenas foi observado alterações na intensidade dos picos difratados pelas amostras ensaiadas. De acordo com o apresentado, conclui-se que o pó de Mandacaru se mostra como uma opção viável como aditivo plastificante em argamassas de cimento sem comprometer a resistência do material.

Introdução: A asma é uma doença inflamatória crônica que afeta mais de 300 milhões de pessoas globalmente, sendo prevalente no Brasil, com cerca de 20% das crianças apresentando sintomas. O manejo inadequado está associado a exacerbações, hospitalizações e custos elevados. Medicamentos convencionais, apesar de eficazes, enfrentam limitações de adesão. Os biológicos surgem como alternativa para casos graves, mas desafios como custo e acesso persistem. Políticas públicas integradas são essenciais para melhorar o controle e a qualidade de vida dos pacientes. Objetivos: Avaliar o impacto da adesão ao tratamento inalatório e do uso de medicamentos biológicos no controle das exacerbações da asma. Metodologia: Revisão integrativa com busca nas bases PubMed e SciELO. Foram incluídos estudos originais que analisaram a eficácia e limitações das intervenções no controle da doença. Resultados: Tratamentos biológicos como mepolizumabe, benralizumabe e reslizumabe reduziram exacerbações em até 50% na asma eosinofílica grave. O mepolizumabe e o benralizumabe destacaram-se na diminuição de internações e uso de corticosteroides. Eventos adversos leves foram predominantes, e melhorias sutis na qualidade de vida e função pulmonar foram observadas. Discussão: Os biológicos mostraram-se eficazes no controle da asma grave, com benefícios significativos em pacientes com altos níveis de eosinófilos. Conclusão: Há limitações na eficácia do reslizumabe em pacientes não eosinofílicos. Pesquisas futuras devem explorar estratificação de pacientes, custo-efetividade e integração com outras intervenções. A inclusão dos biológicos nas diretrizes terapêuticas é crucial para otimizar o manejo da asma e promover maior equidade no acesso.

Published: January 2025

A economia do Paraná vivenciou diferentes períodos econômicos entre eles o da madeira, atividade que permitiu que o estado estivesse sobre a atenção de diferentes madeireiras, primeiramente na extração da matéria-prima araucária e mais tarde na busca de outro tipo de reflorestamento, em especial o pinus e o eucalipto. No decorrer do tempo o Paraná vivenciou a inserção de um novo tipo de atividade madeireira, desenvolvida pelas grandes empresas que chegaram e se articularam, passaram a produzir desde compensados, portas, pisos, madeira para lenha, pelletes entre outro, inserindo o Paraná na internacionalização deste setor. Assim, este trabalho justifica-se por apresentar dados deste setor que ainda continua tendo grande relevância tanto na economia como na indústria paranaense. Com isso, a proposta do trabalho é apresentar uma análise da atividade da madeira no Paraná, buscando entender como a produção madeireira se distribuí no estado a partir de sete polos florestais, enfocando também a sua participação na exportação do produto. O Paraná é um dos maiores produtores de madeira de pinus do país, correspondendo a 57% a produção nacional, justificando também a presença e concentração de importantes empresas do setor madeireiro, que utilizam desta matéria-prima para sua produção. Para isso, buscou-se realizar a interpretação de diversas literaturas e fonte de dados que fossem concernentes à temática proposta para compreender sobre o setor madeireiro do Paraná.

Published: January 2025

O uso de estruturas metálicas na construção civil destaca-se por suas propriedades mecânicas, como alta resistência, durabilidade e sustentabilidade, sendo as treliças metálicas elementos cruciais em coberturas devido à eficiência na distribuição de cargas. Este estudo analisou as alterações no dimensionamento de treliças de aço introduzidas pela atualização da norma NBR 8800 em 2024 em relação à versão de 2008, seguindo três etapas: estudo das normas, dimensionamento de uma treliça conforme cada versão e análise das mudanças. As principais modificações incluem a exclusão do fator Q, a substituição da área bruta pela área efetiva e simplificações em etapas de cálculo, resultando em diferenças expressivas, como nos valores de Nc,Rd, que passaram de 80,91 kN na versão de 2008 para 58,40 kN em 2024, devido à adoção da área efetiva. Além disso, a versão de 2024 reprovou mais barras em relação à anterior. Apesar dessas diferenças, ambas as normas garantem dimensionamentos seguros, mas a atualização de 2024 traz avanços em clareza e eficiência, sendo recomendada para projetos futuros. O estudo reforça a importância da atualização técnica para segurança e conformidade em estruturas metálicas.

Published: January 2025

Pengetahuan yang dimiliki oleh manusia pada dasarnya merupakan hasil upaya yang dilakukan oleh manusia dalam mencari solusi atas permasalahan yang sedang dihadapi. Hal ini merupakan kemampuan alamiah yang dimiliki oleh manusia sebagai bagian dari upaya manusia untuk memenuhi kebutuhan / keinginan yang dimiliki. Dalam artian yang lebih sederhana, pengetahuan merupakan kumpulan informasi, fakta, keterampilan, dan pemahaman yang diperoleh seseorang melalui pengalaman, pembelajaran, atau penelitian. Pengetahuan memungkinkan seseorang untuk memahami, menjelaskan, dan berinteraksi dengan dunia di sekitarnya. Salah satu tokoh yang dikenal dengan konsep pengetahuan adalah Benjamin S Bloom. Bloom (1956) mengenalkan konsep pengetahuan melalui taksonomi bloom yang merujuk pada taksonomi untuk tujuan pendidikan dan telah mengklasifikasikan pengetahuan kedalam dimensi proses kognitif menjadi enam kategori yaitu, pengetahuan (knowledge), pemahaman (comprehension), aplikasi (application), analisis (analysis), sintesis (synthesis), dan evaluasi(evaluation). Model taksonomi ini dikenal sebagai Taksonomi Bloom. Selanjutnya Anderson dan Krathwohl (2001) melakukan revisi mendasar atas klasifikasi kognitif yang pernah dikembangkan oleh Bloom, yang dikenal dengan Revised Bloom’s Taxonomy (Revisi Taksonomi Bloom). Konsep pengetahuan ini terus dikembangkan menyesuaikan dengan perkembangan keilmuan serta tuntutan teknologi yang dibutuhkan dan mampu mendukung kehidupan manusia itu sendiri

Published: January 2025

The golden banana (Musa acuminata Colla) is a typical banana plant in Rokan Hilir. Some parts of the golden banana plant are generally used, however, various other banana organs such as fruit skin, stem midrib, bractea, and golden banana flowers in Rokan Hilir have not been used in medicine. This study aims to determine the content of secondary metabolites and antioxidant activity in various organs of the golden banana.
Simplicia powder from the golden banana organ was extracted by maceration method using 96% ethanol. The extract was then tested for antioxidant activity with a spectrophotometer using the DPPH method at a wavelength of 520 nm.
The results showed that the four organs had very weak antioxidant activity. The highest antioxidant activity was in bractea with an IC50 value of 225.98 ppm and the lowest in flowers with an IC50 value of more than 1000 ppm. The results of the phytochemical screening showed that the four organs of the golden banana from Rokan downstream contained flavonoids, tannins, terpenoids, and saponins but did not contain alkaloids

For a positive integer k, a subset S ⊆ V(G) is said to be a k-dominating set of G if every vertex v ∈ V(G)\S is at a distance of at most k from some vertex of S. The cardinality of the minimum k-dominating set of G is the k-domination number, denoted by γk(G). In this article, we determine the distance k-domination number for two graphs under some product operations in terms of its factor graphs.

Published: January 2025

The social and physical distancing and the rapid transition to remote learning during pandemics had an impact on children’s life regarding educational activities and well being. In this context, the Human-Computer Interaction (HCI) field has faced challenges to design and evaluate computational systems, especially those for learning scenarios. In this paper, we propose an evaluation instrument considering socio-affective aspects of the experience, and present results from a pilot study to evaluate the Aquarela Virtual system. The Aquarela Virtual allows remotely situated children to interact with others by using physical objects related to a children’s song, and emoticons to express their emotions. Based on findings of these evaluations, we provide insights on: a) improvements to be done in the system; b) aspects still to be covered by an evaluation instrument. Even considering the pandemic is now over, hybrid systems such as the Aquarela Virtual system came to stay, and so the need of evaluation instruments such as the proposed one remains.

Cleft Lip/Palate: Hidden Aspects beyond the Gap
Authors: Karmakar Shilpi , Kumar Dixit Pawan
Published: January 2025

Cleft lip/palate is a common congenital anomaly, with 1 in 700 newborns afflicted. Most surgery textbooks teach standard techniques for cleft lip/palate repair. However, there is much deeper science and art behind eradicating the stigma of the cleft. The cleft nose, vermillion, maxilla, and voice are giveaways of a good-but-not-great surgery. Similarly, the failure to address the maxillary hypoplasia, the dentition, the maxillary arches, the hearing, and the speech are common occurrences. This chapter will highlight the broad spectrum of cleft lip/palate conditions and the “why,” “when”, and “how” to address these deformities. Management of cleft lip/palate is a multidisciplinary task, with the child’s welfare at its center.

Данная работа посвящена сравнительному изучению содержания суммы растворимых полифенольных соединений, антиоксидантной и антирадикальной активностей экстрактов растений, произрастающих на территории Республики Казахстан. Эксперименты in vitro были проведены по общепринятой методике определения общего содержания фенольных соединений методом Фолина-Чокальтеу, общую антиоксидантную (восстановительную) активность определяли методом железо - восстанавливающего потенциала (FRAP-метод), антирадикальную активность методом  ингибирования DPPH (1,1-дифенил-2-пикрилгидразил) радикала анализируемыми веществами, с использованием спектрофотометрических методов анализа. Анализ совокупности полученных данных позволяет расположить исследуемые экстракты в следующем ряду в зависимости от количества фенольных соединений и значений антирадикальной и общей антиоксидантной активностей экстрактов: Гармала>Хвощ>Одуванчик>Солодка.
Выявлена выраженная положительная корреляция между содержанием фенольных соединений и всеми показателями антиоксидантных свойств протестированных фитопрепаратов. Среди исследуемых растений выделяются экстракты Гармалы и Хвоща, как демонстрирующие наиболее высокий суммарный антиоксидантный и антирадикальный потенциал. Представленные результаты являются основой для дальнейшего более детального изучения антиоксидантных, антирадикальных и гепатопротекторных свойств растительного лекарственного сырья.

Бұл зерттеудің мақсаты целиакиея ауруы бар адамдар үшін глютенсіз тағамдардың (нан-тоқаш өнімдерінің) май қышқылдарының құрамын бірінші аналитикалық тәсілмен зерттеу. Терапияның негізі глютенді тағамды күндік рационнан толығымен алып тастау болып табылады. Бүгінгі күні дүкендерде целиакиея ауруы бар науқастар үшін таңдауға болатын бірқатар глютенсіз өнімдер бар. Кәдімгі ұнды қарақұмық, күріш, сұлы жармасы, жүгері және ноқаттан жасалған тамақтарға ауыстыруға болады. Бұл дәнді- дақылдар құрамы глютенсіз, сондықтан зерттеу жұмысы өзекті. Ноқат ұнының жоғары биологиялық құндылығы тек ақуыз мөлшерімен ғана емес, сонымен қатар оның аминқышқылдық және жоғарғы май қышқылдарының құрамдық мөлшерімен де бағаланады.
Бұл мақала зерттеуінде өңделмеген және өңделген ноқат ұнының, сондай-ақ одан дайындалған өнімдердің май қышқылдарының құрамы масс-спектрометриялық газ хроматографиясының (ГХ/МС) көмегімен зерттелгені қарастырылған. Осы зерттеуде ноқат ұнының глютенсіз кондитерлік өнімдерді өндіруге жарамдылығын жақсарту бойынша біздің көзқарасымыз микротолқынды пеште термиялық микротолқынды сәулеленумен (СВЧ) өңдеу арқылы ұнның тағамдық құндылығын арттыруға негізделген. Зерттеу барысында ноқат ұны мен одан жасалған өнімдердің құрамының сандық және сапалық өзгерістері зерттелді. Зерттеу нәтежинсі бойынша, ноқат ұнын термиялық өңдеу кезінде (мысалы, профильтроли пісіру процесінде) жоғары майқышқылдық компоненттердің құрамы өзгеретіні соңғы өнімнің тағамдық құндылығына әсер ететіні қарастырылған. Дегенмен, ноқат ұнын пайдаланып жасалған жоғарғы термиялық өңдеу процесінде оның өнімдерінің майқышқылдық, ақуыздық және тағамдық заттар құрамы қажетті мөлшерде қалады.
Алайда, ноқат ұны мен одан жасалған өнімдер биологиялық және тағамдық құндылығы жоғары өнім болғандықтан арнайы диета ұстанатын тұтынушылар мен денсаулығын қадағалайтын адамдар үшін функционалды тамақтанушыларға арналған тартымды тағам бола алады.
