TRABALHANDO COM EDUCAÇÃO EM SAÚDE EM ESPAÇOS NÃO-FORMAIS DE ENSINO E APRENDIZAGEM
Authors: LOPES ROMERO ADRIANO , Da Silva Daniele , Pereira Gabriel Bruno , Bonzanini Romero Rafaelle
Published: December 2020

O presente trabalho consiste de um relato de experiência acerca do desenvolvimento de oficinas temáticas, elaboradas com base nos nove eventos instrucionais de Robert Gagné, sobre Educação em Saúde realizadas com crianças e adolescentes assistidas por Centros de Convivência de uma cidade do interior do Paraná. Foram desenvolvidas quatro oficinas temáticas, de 2 horas de duração cada, sobre Educação em Saúde (abrangendo as vertentes: física, mental e social). A partir dos relatos e relatórios produzidos pelos diferentes grupos de licenciandos que vivenciaram a elaboração, desenvolvimento e avaliação das oficinas temáticas, podemos observar que inicialmente as crianças/adolescentes possuíam uma percepção restrita acerca do tema saúde e que esta foi ampliada após o desenvolvimento das oficinas temáticas. Observamos também que, apesar da heterogeneidade das crianças/adolescentes em termos de idade e nível de escolarização, o desenvolvimento de oficinas temáticas relacionadas ao tema saúde é possível de ser realizado em ambientes não-formais de ensino e aprendizagem. Ao analisar as produções das crianças/adolescentes podemos considerar que há evidências de aprendizagens dos tipos informação verbal, estratégias cognitivas, habilidades intelectuais e atitude.

Published: December 2020

O presente artigo tem por finalidade apresentar alguns resultados de uma pesquisa qualitativa que visou identificar os aspectos sociais e culturais presentes na percepção de alunos do 3ºano do Ensino Médio de cinco escolas integrantes do Núcleo Regional de Educação de Cascavel- PR. Nesse panorama, utilizamos como coleta de dados, uma entrevista áudio gravada com 27 alunos com aprovação prévia do Comitê de Ética em Pesquisa com Seres Humanos. O objetivo foi identificar algumas práticas cotidianas vivenciadas pelos estudantes e como o conhecimento científico e o senso comum estão presentes em suas ações e posturas além dos muros escolares. Como resultado, apontam-se um elevado interesse entre os estudantes sobre assuntos relacionados a Ciência e a Tecnologia, porém seus conhecimentos e atitudes revelam baixa iniciativa ao acesso a informações científicas e tecnológicas. Cabe, portanto, à escola atuar sobre a motivação e a estimulação. A tarefa de estimular também cabe ao governo, juntamente com a comunidade científica, com as instituições de ensino diversas e com a mídia. Todas essas instâncias devem realizar esforços conjuntos para a apropriação do conhecimento, aperfeiçoando formas de popularizar e de ensinar as ciências, promovendo assim a inclusão na cultura científica.

AS YABÁS COMO REPRESENTATIVIDADE NO ENSINO DE FÍSICA DA EDUCAÇÃO BÁSICA
Authors: Taneska Santana Cal Taneska Santana Cal
Published: December 2020

Este trabalho trata das mulheres negras nas ciências, especialmente no ensino de Física. O termo Yabás, em língua yorubá, refere-se a cosmovisão, bem como a divindades africanas. O material didático que ilustra, mobiliza ou narra sobre a mulher negra na produção científica ainda é escasso, bem como os relatos biográficos de mulheres negras cientistas, para trabalhar sobre inclusão e diversidade, no ensino de física, especialmente para educação anti-opressiva. As mulheres cientistas, na história das ciências, com lutas individuais e coletivas, são diferenciais no ensino de física. O objetivo deste trabalho é contribuir para a discussão da diversidade e inclusão no ensino de física. Realizaram-se atividades, de auxílio didático-pedagógico, baseadas nos princípios do designer Richester nas aulas de Física, para estudantes do primeiro ano do ensino médio. A promoção de equidade de gênero e raça, no contexto científico e educacional, no ensino de ciências, atende a demanda de inclusão e diversidade. O resultado deste estudo aponta que o uso de relatos bibliográficos, associados a representatividade, superação de obstáculos e reflexão da sociedade, no ensino de física, está alinhado a educação inclusiva e diversidade.
O ENSINO DE RESISTORES PARA DEFICIENTES VISUAIS, POR MEIO DO USO DE ARDUÍNO
Authors: Dias de Almeida Wesley , Talia Barros Barbosa Nayara , Rosa Valdir
Published: December 2020

O presente trabalho apresenta um estudo sobre as dificuldades que o professor no seu fazer pedagógico ao ter um aluno deficiente visual em sua disciplina. Entre suas dificuldades, está a falta de experiência e de formação continuada. Também, a escassez de materiais adaptados disponíveis, na qual o aluno não consegue acompanhar a turma e se sinta excluído, deixando de mostrar sua potencialidade. O professor que tem alunos com algum tipo de deficiência, muitas vezes, pensa que a melhor maneira de ajudá-lo é facilitando o conteúdo, sendo que todos têm a capacidade de aprender com o uso do material certo. Visando isso, este trabalho apresenta um modelo de ohmímetro adaptado, no qual é possível construí-lo para trabalhar com alunos deficientes visuais, mas todos podem utilizá-los. Com o uso deste material, constatamos que é possível uma inclusão real do aluno deficiente visual e não apenas sua presença durante a aula. Esse material foi idealizado e desenvolvido nas aulas da disciplina de Práticas Pedagógicas no Ensino de Física II com o objetivo de preparar os futuros professores para refletir sobre as práticas de ensino de Física com alunos que apresentem algum tipo de deficiência e mostrar que todos têm a capacidade de aprender.
Bedside Nurses: Champions of Antimicrobial Stewardship
Authors: Sloan Allison M. L. , Dudjak Linda
Published: December 2020

Topic

Microbial organisms include bacteria, viruses, fungi, and parasites. Antimicrobial medications are currently overused or misused, which has resulted in multidrug resistance. Hospitalized patients in the intensive care unit have the highest risk for infections leading to poor outcomes and require successful treatment options.

Clinical Relevance

Inappropriate prescription of antimicrobials places patients and the community at risk for more resistant infections in the future. To prevent misapplication of these important medications, interdisciplinary antimicrobial stewardship programs promote appropriate and safe antimicrobial medication use. Members of these programs are called to be good stewards of antimicrobial medications, incorporating the scope of practice and knowledge of each specialty and the evidence from the literature to develop strategies and protocols for safe and effective antimicrobial medication use.

Purpose of Paper

Nurse involvement in antimicrobial stewardship programs is inadequate, limiting the programs’ potential. Support for increased direct-care nurse participation in antimicrobial stewardship programs is key to improve program targets and patient outcomes.

Content Covered

This article calls for increased nursing awareness of the importance of antimicrobial stewardship programs in clinical practice and greater direct-care nurse involvement in these programs.
Using In Situ Simulation to Develop a Prone Positioning Protocol for Patients With ARDS
Authors: Montanaro Jessica
Published: December 2020

Background

Acute respiratory distress syndrome carries a 40% mortality rate. Prone positioning remains underused owing to clinicians’ low degree of confidence, concern about the risk of adverse outcomes, and lack of staff competency training.

Local Problem and Purpose

A prone positioning protocol and educational program were needed in an intensive care unit to achieve compliance with best practices for treating acute respiratory distress syndrome patients.

Methods

An initial survey was conducted to measure staff confidence and competency in prone positioning. A literature review was performed, and a plan-do-study-act approach was used to develop a protocol through in situ simulation involving mock patients. A training video and a simulation scenario using a high-fidelity manikin were developed to facilitate staff education. Staff were surveyed again after training.

Interventions

During the simulation scenario, interdisciplinary clinicians learned to apply the protocol and resupinate the patient during a simulated emergency. The training video was later used for “just in time” education minutes before actual prone positioning events.

Results

A total of 25 critical care nurses, 11 respiratory therapists, and 10 physicians completed the initial survey and simulation training. The survey showed that staff lacked confidence and competency in prone positioning. Staff demonstrated competence during the simulation sessions, and posttraining surveys indicated increased confidence. After the educational program, prone positioning was successfully used for 6 critically ill acute respiratory distress syndrome patients.

Conclusions

In situ simulation and interdisciplinary collaboration increase standardization of high-risk, underused procedures, improving staff confidence and competence as well as patient safety.
Small incision lenticule extraction retreatment in a patient with high residual refractive error after photorefractive keratectomy
Authors: Kankariya Vardhaman P , Grentzelos Michael A , Dube Ankita B , Kymionis George D , Pallikaris Ioannis G
Published: December 2020

A 36-year-old male underwent uneventful small incision lenticule extraction (SMILE) for the correction of his high residual refractive error 12 years after photorefractive keratectomy (PRK). Preoperatively, uncorrected distance visual acuity (UDVA) was counting fingers in both eyes. Corrected distance visual acuity was 20/20 in the right and 20/30 in the left eye due to amblyopia. One month after SMILE, UDVA was 20/20 and 20/30 in the right and left eye, respectively; post-PRK corneal haze had reduced. During the 4-year follow-up, UDVA remained stable and there were no complications. SMILE could be a good alternative approach for retreatment in post-PRK patient.
The perspectives of interleukin-10 in the pathogenesis and therapeutics of multiple myeloma
Authors: Liu Cheng-Der , Chang Chun-Chun , Huang Wei-Han
Published: December 2020

Multiple myeloma (MM) is typically featured by the increased levels of inflammatory cytokines in the neoplastic plasma cells (PCs) producing monoclonal immunoglobulin. PCs proliferate in the bone marrow, which will lead to extensive skeletal destruction with osteolytic lesions, osteopenia, or pathologic fractures. The diagnostic biology of MM has progressed from morphology and low-sensitivity protein analysis into multiomics-based high-throughput readout, whereas therapeutics has evolved from single active agent to potential active drug combinations underlying precision medicine. Many studies have focused on the cytokine networks that control growth, progression, and dissemination of the disease. The complexity of cytokines in MM development remains to be elucidated comprehensively. Apart from knowing that interleukin (IL)-6 is important in the pathogenesis of MM, it has been shown that IL-6 is a paracrine factor supplied by the microenvironment comprising of those cells from the myeloid compartment. Due to IL-10 was considered an immunosuppressive cytokine to promote cancer escape from immune surveillance, the role of IL-10 in this regard has been underestimated although recent advances have reported that IL-10 induces both PC proliferation and angiogenesis in MM. In addition, cumulative studies have suggested that IL-10 plays an important role in the induction of chemoresistance in many cancers; a virtual requirement of autocrine IL-10 for MM cells to escape from an IL-6-dependent proliferation loop was implicated. In this review, we summarize the available information to elucidate a new understanding of the molecular and functional roles of IL-10 in MM.

Why Keep the Old Dead Around?
Authors: Ion Alexandra
Published: December 2020

The aim of this article is to focus on the ways in which communities imagined their relationship with the dead throughout the Balkan area during the Neolithic and Eneolithic (6200–3800 cal BC). My claim is that we should go beyond seeing the human remains discovered in settlements as unusual/atypical/non-funerary discoveries. Instead, they can be read as traces of complex funerary practices, which contributed to the creation and manipulation of collective identities. The dead became part of a place-making strategy, they fixed time and become central to certain kinds of assemblages, which in turn were meant to create more powerful ancestors who could intervene in the present.
Revisiting Prebuilding Dodona
Authors: Vasileiou Eleni
Published: December 2020

The aim of this paper is to put together the currently dispersed information about the occurrence of architectural remains at the archaeological site of Dodona during the so-called prebuilding phase, mainly at the end of the Late Bronze Age-Beginning of Early Iron Age through the reports and diaries of the site’s excavators. Moreover, the combination of the architectural remains with the portable finds will lead to suggestions about the site’s character during late prehistory. Was it a humble village inhabited by stockbreeders, or a hypaethral sanctuary?
How do we avoid imposing the present on the past when modelling spatial interactions?
Authors: Rivers Ray J. , Evans Tim S.
Published: December 2020

Theoretical archaeological modelling for describing spatial interactions often adopts contemporary socioeconomic ideas whose 20th-century language gets translated into historical behaviour with the simplest of lexicons. This can lead to the impression that the past is like the present. Our intention in this paper is that, when this happens, we strip out as much of the contemporary context as we can, to bring modelling back to basic epistemic propositions. We suggest that although the underlying ontology may be specific to contemporary society the epistemology has much greater generality, leading to essentially the same conclusions without the carapace of intricate economics.
Habitat Selection and the Evolutionary Aesthetics of Landscape Preference
Authors: Škorić Marko , Kišjuhas Aleksej
Published: December 2020

This paper analyses the processes of habitat selection and human landscape preferences from an evolutionary perspective, with the aim of demonstrating how humans aesthetically choose, assess and aspire to live in an environment in which our species and our ancestors evolved in during the pre-Neolithic period. We present the basics of evolutionary aesthetics, then analyse the process of habitat selection and the most influential evolutionary theories of landscape preference. Finally, we refer to applied empirical research and point out that a comprehensive evolutionary theory must also take into account the psychological and cultural elements that affect human well-being.
Are We Creating Our Past?
Authors: Girotto Chiara G. M.
Published: December 2020

Urnfield Culture hilltop settlements are often associated with a predominant function in the settlement pattern. This study challenged the idea of centrality by means of density estimates and spatial inhomogeneous explanatory statistics. Reflecting on the differences in spatial trends and material culture, no conclusive evidence for a consolidation of power, economic, or cultic dominance was observed. The dataset strongly points towards the inapplicability of commonly used parametric and/or homogenous spatial algorithms in archaeology. Tracer variables as well as the methodological and theoretical limitations are critically reviewed and a methodological framework to increase the reproducibility and reusability of archaeological research is proposed.
Bayesian 14C-rationality, Heisenberg Uncertainty, and Fourier Transform
Authors: Weninger Bernhard , Edinborough Kevan
Published: December 2020

Following some 30 years of radiocarbon research during which the mathematical principles of 14C-calibration have been on loan to Bayesian statistics, here they are returned to quantum physics. The return is based on recognition that 14C-calibration can be described as a Fourier transform. Following its introduction as such, there is need to reconceptualize the probabilistic 14C-analysis. The main change will be to replace the traditional (one-dimensional) concept of 14C-dating probability by a two-dimensional probability. This is entirely analogous to the definition of probability in quantum physics, where the squared amplitude of a wave function defined in Hilbert space provides a measurable probability of finding the corresponding particle at a certain point in time/space, the so-called Born rule. When adapted to the characteristics of 14C-calibration, as it turns out, the Fourier transform immediately accounts for practically all known so-called quantization properties of archaeological 14C-ages, such as clustering, age-shifting, and amplitude-distortion. This also applies to the frequently observed chronological lock-in properties of larger data sets, when analysed by Gaussian wiggle matching (on the 14C-scale) just as by Bayesian sequencing (on the calendar time-scale). Such domain-switching effects are typical for a Fourier transform. They can now be understood, and taken into account, by the application of concepts and interpretations that are central to quantum physics (e.g. wave diffraction, wave-particle duality, Heisenberg uncertainty, and the correspondence principle). What may sound complicated, at first glance, simplifies the construction of 14C-based chronologies. The new Fourier-based 14C-analysis supports chronological studies on previously unachievable geographic (continental) and temporal (Glacial-Holocene) scales; for example, by temporal sequencing of hundreds of archaeological sites, simultaneously, with minimal need for development of archaeological prior hypotheses, other than those based on the geo-archaeological law of stratigraphic superposition. As demonstrated in a variety of archaeological case studies, just one number, defined as a gauge-probability on a scale 0–100%, can be used to replace a stacked set of subjective Bayesian priors.
Beyond the Jordan
Authors: Finlayson Bill , Makarewicz Cheryl A.
Published: December 2020

Recent excavations in Jordan have demonstrated a long sequence of development from the late Pleistocene Epipalaeolithic through the early Holocene Pre-Pottery Neolithic. Superficially, the growing body of social and subsistence evidence suggests Neolithic communities emerged from traditions rooted in the early Epipalaeolithic. However, while developments such as the construction of shelters, population aggregation, and subsistence intensification may be essential for the emergence of a Southwest Asian Neolithic, they are typical of contemporary hunter-gatherer societies and not inherently Neolithic. Notably, the Neolithic in Southwest Asia was not a homogenous entity, but instead supported diverse expressions of subsistence, symbolic behaviours, and cultural trajectories across the region. To understand the emergence and development of the Neolithic, we need to examine this richly diverse history and its many constituent pathways.
Understanding Diversity in Early Neolithic Pottery Production
Authors: Dzhanfezova Tanya , Doherty Chris , Grębska-Kulow Małgorzata
Published: December 2020

By recovering and interpreting the hidden technological variability in the first pottery at Ilindentsi-Massovets, this paper reveals the innovative adaptations to local conditions that the adoption of pottery production, as a new technology, must have involved. Seventy-one samples were analysed using low-resolution binocular microscopy and high-resolution petrographic and scanning electron microscopy. The variety established within each of the major components in pottery production at the site is interpreted in the context of the local raw materials (availability) and technological approaches (decision making), thus reaching beyond the traditional interpretative models that suggest large-scale uniformity in Early Neolithic pottery production across extensive European regions.
Temporality and biography in tourism: a qualitative longitudinal approach
Authors: Crossley Émilie
Published: December 2020

Temporality is increasingly being recognised as an important dimension of tourist experience. Qualitative longitudinal research (QLR) is a methodology for investigating temporality and change that is rarely used in tourism studies. The approach moves away from reliance on data collected at one point in time and retrospective narratives. Instead, data are generated at multiple points in time, thus capturing experience in the present moment. I situate QLR alongside lifecourse and biographical research in order to show how it can extend existing qualitative enquiry into tourists’ subjective temporal experiences and biographical narratives. ‘Intensive’ and ‘extensive’ QLR designs are delineated and connected to potential applications in qualitative tourism research. Additionally, conceptual clarification is provided regarding use of the terms ‘longitudinal’ and ‘temporal’, which have frequently been a source of confusion. I conclude that QLR has significant potential to advance our understanding of tourist experience, motivation and transformation.
DAPA: Differential Analysis aided Power Attack on (Non-) Linear Feedback Shift Registers
Authors: Sim Siang Meng , Jap Dirmanto , Bhasin Shivam
Published: December 2020

Differential power analysis (DPA) is a form of side-channel analysis (SCA) that performs statistical analysis on the power traces of cryptographic computations. DPA is applicable to many cryptographic primitives, including block ciphers, stream ciphers and even hash-based message authentication code (HMAC). At COSADE 2017, Dobraunig et al. presented a DPA on the fresh re-keying scheme Keymill to extract the bit relations of neighbouring bits in its shift registers, reducing the internal state guessing space from 128 to 4 bits. In this work, we generalise their methodology and combine with differential analysis, we called it differential analysis aided power attack (DAPA), to uncover more bit relations and take into account the linear or non-linear functions that feedback to the shift registers (i.e. LFSRs or NLFSRs). Next, we apply our DAPA on LR-Keymill, the improved version of Keymill designed to resist the aforementioned DPA, and breaks its 67.9-bit security claim with a 4-bit internal state guessing. We experimentally verified our analysis. In addition, we improve the previous DPA on Keymill by halving the amount of data resources needed for the attack. We also applied our DAPA to Trivium, a hardware-oriented stream cipher from the eSTREAM portfolio and reduces the key guessing space from 80 to 14 bits.
The Area-Latency Symbiosis: Towards Improved Serial Encryption Circuits
Authors: Balli Fatih , Caforio Andrea , Banik Subhadeep
Published: December 2020

The bit-sliding paper of Jean et al. (CHES 2017) showed that the smallest-size circuit for SPN based block ciphers such as AES, SKINNY and PRESENT can be achieved via bit-serial implementations. Their technique decreases the bit size of the datapath and naturally leads to a significant loss in latency (as well as the maximum throughput). Their designs complete a single round of the encryption in 168 (resp. 68) clock cycles for 128 (resp. 64) bit blocks. A follow-up work by Banik et al. (FSE 2020) introduced the swap-and-rotate technique that both eliminates this loss in latency and achieves even smaller footprints.In this paper, we extend these results on bit-serial implementations all the way to four authenticated encryption schemes from NIST LWC. Our first focus is to decrease latency and improve throughput with the use of the swap-and-rotate technique. Our block cipher implementations have the most efficient round operations in the sense that a round function of an n-bit block cipher is computed in exactly n clock cycles. This leads to implementations that are similar in size to the state of the art, but have much lower latency (savings up to 20 percent). We then extend our technique to 4- and 8-bit implementations. Although these results are promising, block ciphers themselves are not end-user primitives, as they need to be used in conjunction with a mode of operation. Hence, in the second part of the paper, we use our serial block ciphers to bootstrap four active NIST authenticated encryption candidates: SUNDAE-GIFT, Romulus, SAEAES and SKINNY-AEAD. In the wake of this effort, we provide the smallest block-cipher-based authenticated encryption circuits known in the literature so far.

Published: December 2020

The present study aims to examine the anxiety to catch COVID-19 from the viewpoint of elite athletes and sedentaries based on different variables. The Individual Anxiety sub-dimension of the Athlete’s Anxiety to Catch the Novel Coronavirus (COVID-19) Scale was applied. According to the study results, athletes had lower levels of anxiety to catch COVID-19 compared to sedentaries. It was concluded that female participants had higher levels of anxiety compared to male participants. It was also determined that female elite athletes also had higher levels of anxiety compared to male elite athletes. When the anxiety to catch COVID-19 was examined by age group, it was observed that elite athletes under the age of 19 had significantly lower levels of individual anxiety compared to other age groups. Additionally, it was found that male elite athletes had lower levels of anxiety compared to male sedentaries.

El desarrollo sostenible es un tema de interés desde hace más de tres décadas, derivado de lo cual, se han elaborado diversas soluciones que buscan implementar y controlar el desarrollo sostenible en las empresas. El sector de energía hidroeléctrica busca atender sus problemáticas ambientales y sociales a través de diversos modelos. El objetivo de este trabajo es seleccionar un modelo de desarrollo sostenible para evaluar la sostenibilidad hidroeléctrica mediante un método de toma de decisiones. Mediante el método proceso analítico jerárquico (AHP) y un grupo de enfoque se determinan las ponderaciones de los criterios, subcriterios y alternativas de los modelos de desarrollo sostenible. Una vez utilizado el método AHP se jerarquizaron los modelos de desarrollo sostenible, se determinó que el modelo del protocolo del IHA obtuvo la mayor ponderación, seguido de los modelos del BS 8900 y el Dow Jones Sustainability Indexes. En el análisis de sensibilidad se validó la selección del modelo del protocolo de la IHA. Los resultados presentados confirman que el protocolo de la IHA es el modelo de desarrollo sostenible más apropiado para evaluar la sostenibilidad hidroeléctrica, lo que proporciona apoyo a quienes buscan justificar su decisión de seleccionar un modelo de desarrollo sostenible, mediante métodos multicriterio.

En el estudio de los sistemas de bienestar la relación entre el gasto social y los indicadores de vulnerabilidad como la tasa de pobreza o índices de desigualdad de ingresos tienen gran interés en la literatura. Este trabajo evalúa la productividad del gasto social de los estados de la EU15 (los estados de bienestar más consolidados de la EU28), en el período 2011-2015, con metodología Análisis Envolvente de Datos. Posteriormente, con un método clustering difuso identificamos los patrones existentes de gasto social y su eficiencia. Observamos tres grupos de países. El primero engloba la mayor parte de estado del bienestar nórdico y continental. El segundo grupo, conformado por Luxemburgo e Irlanda, son países con el menor volumen de gastos social sobre PIB pero a la vez son países eficientes. El tercero engloba a los estados del bienestar mediterráneos, junto con Gran Bretaña, que son los menos eficientes en la reducción de los indicadores de vulnerabilidad.
EXPLORING ACTIVE EUROPEAN CITIZENSHIP: AN EXPERIMENTAL PROJECT OF PROMOTION AND COMMUNICATION
Authors: Giacomelli Elena , Zingone Michela
Published: December 2020

The European Union celebrates its thirty years anniversary in a peculiar historical moment characterized by crises and emergencies. Being able to count on an informed and active citizenship becomes increasingly necessary. Universities, schools and institutions are teaming up in order to propose projects for sharing information about and promoting the European Union involving all its citizens. Young people, in particular, are identified among the first interlocutors, to whom we entrust communication between peers, exploiting the potential of digital media. In a context often dominated by fake-news, complete and source-aware information about the European Union becomes an essential tool for citizens' empowerment. This article proposes a reflection starting from a multi-sited research conducted in the Italian cities of Bologna, Forlì and Ravenna through a project of the University of Bologna and the Emilia-Romagna Region entitled "Promoting active European citizenship in times of crisis". Through participant observation, the article reflects on the results emerged from word-cafés, workshops and meetings with citizens developed in three different territorial areas and with the involvement of three different targets: first and second grade high school students, university students and adult citizens.

ФИЗИКО-ХИМИЧЕСКАЯ ХАРАКТЕРИСТИКА АГАРА ИЗ КРАСНЫХ ВОДОРОСЛЕЙ РОДА AHNFELTIA: РЕКОМЕНДАЦИИ ПО ЕГО ПРИМЕНЕНИЮ
Authors: Бурова Наталья Викторовна , Подкорытова Антонина Владимировна
Published: December 2020

Представлены результаты исследований физико-химических характеристик агаров из недоиспользуемых красных водорослей Ahnfeltia tobuchiensis и A. plicata, заготовленных в промысловые сезоны 2016-2018 гг., с целью оценки перспектив сбора и переработки этого сырья в процессе производства отечественных гидроколлоидов. Водоросли были добыты способом активного лова в заливе Петра Великого Японского моря, а также собраны из штормовых выбросов на побережьях лагуны Буссе о-ва Сахалин, Соловецких о-вов и Онежского залива Белого моря. Согласно полученным данным выход природного агара из A. tobuchiensis составляет в среднем 3,9, из A. plicata – 9,0 %, а модифицированных щёлочью агаров из дальневосточной и беломорской анфельции – 10,7 и 19,7 % соответственно. В статье представлены коэффициенты эффективности последовательных экстракций агара, развёрнутые данные по содержанию агаровой фракции и неагаровых примесей в неочищенных экстрактах анфельции, а также корреляционный анализ, характеризующий зависимости между этими фракциями. Изучены такие свойства полученных гидроколлоидов, как прочность, прозрачность, температуры застудневания и плавления гидрогелей 0,85%-ных растворов агаров, а также содержание минеральных и азотистых веществ. С помощью ранговых корреляций Спирмена выявлены зависимости между выходом агара и его физико-химическими характеристиками. В результате проведённых исследований установлено, что модифицированный агар из A. tobuchiensis удовлетворяет требованиям ГОСТ 16280 «Агар пищевой» и ГОСТ 17206 «Агар микробиологический». Штормовые выбросы A. plicata являются полноценным сырьём для изготовления пищевого агара высшего сорта. Проведённые исследования показывают высокое качество полученных полисахаридов и целесообразность использования красных водорослей рода Ahnfeltia, не только добываемых активным ловом, но и их штормовых выбросов, для производства агара. Очевидна перспективность практического применения представленных данных при разработке программ импортозамещения гелеобразующих полисаха-ридов.
ЭКОЛОГИЧЕСКАЯ ОЦЕНКА ХИМИЧЕСКИХ СВОЙСТВ ПОЧВ
ПРИМОРСКОЙ РЕКРЕАЦИОННОЙ ЗОНЫ В ПОСЕЛКЕ ГОРОДСКОГО ТИПА ЯНТАРНЫЙ

Published: December 2020

Исследования проводились в парковой рекреационной зоне, которая расположена вдоль абразионного побережья Балтийского моря в поселке городского типа (пгт) Янтарный Калининградской области. Для диагностики почв были за-ложены разрезы глубиной 150–250 см. Пробы почв отбирались из каждого гори-зонта. В образцах почв определялись рН, содержание органического углерода (с последующим пересчетом на гумус), подвижных соединений фосфора, калия, тяжелых металлов (Cu, Zn, Pb, Cd, Ni, Cr(3+)) и валовое количество ртути. Реакция среды в профиле почв находилась в интервале от слабокислой до нейтральной. В почвах северо-западной части парка им. М. Беккера обнаружены карбонатные горизонты на глубине свыше 80-100 см. Максимальное количество гумуса в почвах сосредоточено в слое 0 – 10 см. В среднем оно равно 3,30±0,10 % (пределы варьирования 3,00–4,45 %). Эти величины являются типичными для лесных почв на супесчаных и песчаных породах в автоморфных условиях региона. Распределение гумуса по профилю зависит от генезиса и варьирует от резко убывающего до равномерно убывающего. В четырех из восьми почвах обнаружены погребенные профили разной сохранности. Содержание органического вещества в гумусовых горизонтах погребенных почв варьирует в пределах от 1,19 до 3,99 %. Почвы рекреационной зоны содержат очень высокое количество подвижного фосфора (более 250 мг/кг) как в гумусовых горизонтах, так и в почвообразующих породах. Это объясняется примесью фосфоритов и является геохимической особенностью пород Замландского п-ова. Количество подвижного калия максимально в гумусовых горизонтах (100 – 278 мг/кг). Распределение калия по профилю резко убывающее. Почвообразующие песчаные породы имеют очень низкое содержание подвижного калия. Количество тяжелых металлов (Cu, Zn, Pb, Cd, Ni, Cr(3+)) и валовой ртути ниже предельно-допустимых концентраций.

Настоящая статья посвящена изучению распределения температур по объему насыпи пищевого, крахмал- или пектинсодержащего сырья при его хранении в специализированных силосах. Объектом исследований явились краевые условия для хранения сырья в среде, максимально соответствующей реальным условиям при активном вентилировании. Несмотря на важность решения вопросов, связанных с прогнозированием формирования тепло-влажностных полей при хранении изучаемых насыпей и зависящих от них изменений технологических свойств сы-рья, в настоящее время имеющихся математических описаний этих сопряженных явлений недостаточно. Это объясняется сложностью и малоизученностью процессов хранения пищевых насыпей как на микро-, так и на макроуровне. Такие массы представляют собой систему с распределенными параметрами. Существенной особенностью, значительно влияющей на изучаемые распределения температур, является возможность возникновения в пищевых насыпях такого рода новых внутренних источников теплоты и влаги. Образование подобных источников обусловлено в некоторых случаях эффектом «самосогревания», появляющимся благодаря происходящим в насыпи биологическим процессам типа «дыхания» отдельных ее элементов, как, например, внутри хранящейся зерновой массы. В связи с этим возможность прогнозирования полей тепло- и влагосодержания зависит, с одной стороны, от полноты необходимой информации о влажности и температуре компонентов массы в исходный момент, с другой – от надежности математической модели, способной на основе этой информации, используемой для задания краевых условий и теплофизических констант, описать реальные процессы теплопереноса в насыпи. Актуальность статьи состоит в том, что анализ характера особенностей тепломассобмена в дискретной насыпи пищевого продукта может быть осуществлен только на основании сформированных аналитических моделей.

Предложены два способа переработки покровных тканей гидробионтов (рыбья чешуя, кожа с чешуей), позволяющие получить продукцию различного назначения, в том числе косметический скраб из чешуи рыб, имеющий привлека-тельный внешний вид, естественную гамму оттенков цвета и запах природного происхождения (без рыбного запаха). Сущность обоих способов заключается в предварительной очистке чешуи от различных примесей органического проис-хождения с последующей ее термической обработкой в жидкости при 85–100 0С. В качестве последней используются овощные, фруктовые, ягодные соки, молочная сыворотка, содержащие различные органические кислоты (яблочную, молочную и т. д.). Термически обработанную чешую отделяют от жидкости, при необходимости смешивают с компонентами растительного происхождения (злаковых, травяных сборов), высушивают, измельчают и фракционируют с получением частиц косметического скраба различной степени дисперсности. Представлены органолептические показатели и химический состав (общий, аминокислотный, тяжелых металлов) образцов сырья (рыбья чешуя) и готовой продукции (косметический скраб). Определено, что в процессе термогидролиза чешуи судака (Sander lucioperca) в жидкости (яблочном соке) происходит снижение массовой доли белка с 40,99 до 30,87 %, кальция – с 21,28 до 17,20 %, фосфора – с 8,60 до 5,40 % при увеличении содержания углеводов до 13,4 % (за счет компонентов сока, перешедших на рыбью чешую в процессе ее термогидролиза). Показано, что с ростом продолжительности термогидролиза рыбьей чешуи уменьшается ее жесткость (истирается пальцами рук) и увеличивается количество более мелких фракций (абразива).

İleriye dönük olarak şehirleşmenin ve fiziki imkanların yüksek standartlarda oluşturulmasını amaçlar. İmar planları yapılırken, kamu menfaati, toplumun refahı ve gereksinimleri ön planda tutulmalıdır. Önemine binaen çalışmada en çok üzerinde durulan imar planları, nazım imar planları ile uygulama imar planlarıdır. İmar Hukuku’nun temel kaynağı İmar Kanunu olup, planların yapımı için hem mahalli idareler hem de Bakanlık yetkili kılınmıştır. Yetkili kuruma göre birtakım farklılıklar içeren imar planlaması faaliyeti, belirli ilkeler ve usuller çerçevesinde gerçekleştirilmelidir. İmar planlarının değiştirilmeleri, çok sık karşılaşılan bir durum olmamalıdır. Ancak mutlaka değiştirilmesi gerekiyorsa, kamunun ihtiyaçları gözetilerek yapılmalıdır. İmar planları, idarelerce kendiliğinden ya da menfaati olanların açacağı iptal davası vasıtasıyla değiştirilebilir, iptal edilebilir.

The Transmission of Global Commodity Prices to Consumer Prices in a Commodity Import-Dependent Country: Evidence from Morocco
Authors: El-Karimi Mounir , Ahmed El-Ghini
Published: December 2020

This paper uses the Breitung and Candelon (2006) causality test to examine the effect of global oil and food price changes on the inflation in Morocco over the period from 1998Q1 to 2018Q1. The results show significant transmission from oil and food prices to domestic inflation. Specifically, the food prices are shown more important than oil prices in explaining inflation in the short-run, which reflects the high weight of food in the consumption basket. However, the effect of oil prices on inflation is much more persistent than the effect of food prices. Furthermore, the impact of commodity price shocks on inflation exhibits asymmetries. The oil price hikes affect more weakly the inflation than oil price decreases, whereas the food price increases are more transmitted to inflation than food price decreases. Our findings may provide useful information to researchers and policymakers in formulating more appropriate monetary policy.

Visual impact is essential when consumers are assessing car preferences. The purpose of this paper is to present a holistic model focusing on car aesthetic dimensions and its impact on consumers’ purchase decisions. Our findings are based on a questionnaire completed by 388 participants and analyzed with SPSS and AMOS. The results show not only that the aesthetic dimensions such as color, shape and sound influence the processing stimuli, but also the significant and positive relationships established between the stimuli and the purchase decision. Also, this study can guide marketers when developing an effective marketing strategy. As our research focuses on the Romanian market, testing our framework in different cultures is strongly encouraged.

Published: December 2020

For more than a quarter of a century, China has experienced a significant economic growth. Yet, this rapid growth has brought on many economic, social and environmental challenges, which might negatively influence the future development of the country. The objective of this paper is to analyse the Chinese economic evolution in order to determine if its growth model is sustainable over time. The research methods consisted in an investigation of the specialized literature, which helped us formulate four research hypotheses, and in a statistical analysis of secondary data, which allowed us develop four models, in order to test the hypotheses. The conclusions show that, to sustain the growth rate, China needs to increase its human capital stock, to keep the pace of attracting the foreign investments, to reduce the size of the government, to diminish the public consumption and to invest in the renewable energy, for increasing the energy efficiency.
