O documentário como ferramenta de divulgação científica: o que dizem as pesquisas na área de educação em ciências?
Authors: Siqueira Palcha Leandro , Wendler Miranda Brenno , Nicolas Guimarães Vosch Daniel , Dias Domiciano Tamara
Published: February 2022

Resumo: Cada vez mais a Educação em Ciências necessita de alternativas para um aprendizado mais significativo e o cinema de divulgação científica, representado pelos documentários, pode ser um caminho eficiente para isso. O objetivo principal desta pesquisa reside em analisar trabalhos publicados no Encontro Nacional de Pesquisa em Educação em Ciências, no período de 2011 a 2019, estabelecendo o panorama sobre o uso de Documentários de Divulgação Científica no contexto das aulas de Ciências. Em termos metodológicos, realizou-se uma pesquisa bibliográfica e utilizou-se o referencial da Análise de Discurso Francesa para organizar os dados e averiguar as publicações que tratavam do uso deste tipo de mídia no ambiente de ensino em sala de aula. Pôde-se notar que, apesar dos poucos trabalhos tratando desta temática, os documentários de divulgação científica possibilitaram um maior entendimento por parte dos estudantes quanto aos conceitos científicos. Dentre os trabalhos analisados apenas um abordou o Ensino Fundamental, necessitando futuras investigações acerca desta etapa de ensino. Conclui-se que os documentários de divulgação científica, apesar das poucas pesquisas sobre o uso em sala de aula, são recursos promissores para mobilizar o Ensino de Ciências, porém devem ser buscados métodos de ensino que os incluam de forma contextualizada e problematizada às aulas de Ciências, a fim de que os estudantes possam compreender, refletir e divulgar os conhecimentos científicos.

Frequência escolar e ensino remoto: desafios à educação em tempos de pandemia
Authors: Cavalcanti de Albuquerque Larissa , Laurentino Diniz Ercules , Jezine Mesquita de Araújo Edineide , De Almeida Baptista Maria das Graças
Published: February 2022

Resumo: A pandemia da Covid-19 impôs uma série de desafios à escola, sendo a frequência escolar um desses. A difícil tarefa consistiu em assegurar a continuidade dos estudos sem a possibilidade de acesso às escolas de forma presencial. Diante de tal cenário, o presente trabalho tem por objetivo avaliar o nível de participação dos estudantes a partir das atividades remotas durante o período de pandemia entre os meses de abril e dezembro de 2020. Para tanto, foram pesquisados os acessos de estudantes à plataforma Google Classroom durante 30 semanas de atividades remotas. Os estudantes pesquisados se encontram matriculados em turmas dos anos finais do Ensino Fundamental em uma escola situada no município de João Pessoa-PB. Trata-se de uma pesquisa de cunho qualitativo e de caráter descritivo. Conclui-se que, em um contexto de vulnerabilidade social, embora as propostas tecnológicas apresentadas pela escola sejam muito importantes para a garantia da continuidade dos estudos, elas não se constituem opção para muitos estudantes que se encontram destituídos do processo de inclusão digital. Acreditamos que as propostas para o pós-pandemia devem ser elaboradas levando em consideração resultados como os apresentados no presente artigo, sem os quais as respostas ao problema serão inócuas para a vida de grande parte dos estudantes brasileiros.

Authors: Gonçalves Brito de Arruda Silvana , Oliveira Francisco de Assis José de , Cavalcante Lima Kênio Erithon
Published: February 2022

Resumo: A necessidade de inclusão das Tecnologias Digitais da Informação e da Comunicação às práticas pedagógicas é crescente para atender a uma geração de jovens, cada vez mais, tecnológica. Nesse sentido, o presente estudo teve como objetivo avaliar a aplicabilidade do laboratório virtual numa perspectiva investigativa em uma Sequência Didática Interativa (SDI) para o estudo de Bioquímica no contexto da obesidade. A proposta metodológica adotada foi baseada tanto na intervenção pedagógica de um laboratório virtual e quanto nos estudos de caso aplicados à uma SDI sobre a temática obesidade com estudantes do 1º Ano do Ensino Médio. Os resultados foram construídos por decorrências das intervenções dos estudos de caso, nas simulações, nos cálculos de IMC, ratificados na comparação dos resultados dos questionários no início e no término da SDI. Constatamos que o uso dessa ferramenta tecnológica, com simulações, permitiu que os estudantes desenvolvessem etapas de um processo investigativo e melhor compreendessem os conteúdos abordados, contribuindo no fomento de novas aprendizagens, o que confirma a importância de tecnologias educativas no processo de ensino e aprendizagem dos conhecimentos biológicos.

A escolha pela docência e suas relações de forças: compreensões e multiplicidades no cerne de um grupo de estudos e pesquisas em educação
Authors: Monteiro Rigue Fernanda , Copetti Dalmaso Alice
Published: February 2022

Resumo: Este estudo visa identificar e compreender que forças contingenciaram a escolha pela docência enquanto profissão pesquisadoras vinculadas a um Grupo de Estudos e Pesquisas em Educação. O fazemos a partir de uma escrita ensaística (LARROSA, 2003) que permite vislumbrar as multiplicidades que as levaram a escolher a profissão docente, tramando algumas linhas que constituem a malha de um ambiente formativo que é tecido em meio às diferentes trilhas da existência das pesquisadoras no contexto universitário brasileiro. Resulta do estudo que: os vínculos e as experiências vivenciadas no cerne dos ambientes familiares toma lugar de destaque em como as integrantes do Grupo perceberam e buscaram sua futura ação profissional; as afetações que as professoras produziram em seus corpos como força importante para a escolha da docência como profissão; a experimentação vivenciada na infância, nas brincadeiras, nas aulas direcionadas às bonecas e aos irmãos, como promotora de uma alegria que ficou registrada na memória corporal dessas professoras e futuras professoras; as representações sociais que pairam sob a docência por vezes se caracterizam como um ponto problemático que, por vezes, impede e dificulta a opção pela formação superior em licenciatura. Logo, conclui-se que a escolha pela profissão docente é marcada por diferentes polifonias e multiplicidades que demandam cultivarmos uma permanente atitude ética que respeite e permita às integrantes do Grupo estarem se modulando livremente, com base em suas leituras de mundo e também de proximidade com as versões multifacetadas da docência.

Um sistema de notificação inteligente
Authors: Souza Mariana , Okuyama Fabio Yoshimitsu
Published: February 2022

Resumo: Com a modalidade da Educação a Distância (EaD), o conhecimento tornou- se mais acessível devido à facilidade de ingresso do aluno na instituição pretendida, ao tempo e local de estudos de que dispõem. No entanto, a grande quantidade de alunos que a modalidade permite atender implica, também, na necessidade de acompanhar e avaliar o ensino na mesma proporção em que é ofertado. Neste contexto, a tutoria tem papel fundamental nesse processo, apesar de enfrentar grande dificuldade na manutenção dessa prática. Visando contribuir para minimizar esta dificuldade, foi idealizado um Modelo de Notificação Inteligente, desenvolvido para atuar em cursos abertos, estimulando os estudantes, por meio do envio de mensagens automatizadas e personalizadas, a concluírem os cursos. O objetivo é atenuar a alta taxa de evasão que permanece no cenário da EaD a partir de uma metodologia de notificação inteligente que considerou o perfil do aluno como base para seu desenvolvimento, no sentido de rendimentos acadêmicos e de predileções pessoais, culminando em mensagens interativas altamente personalizadas. SINTA, o modelo de notificação inteligente, foi delineado e aplicado, parcialmente, em um curso aberto, obtendo duas leituras de retorno positivo: 40% com alunos que corresponderam ativamente e 20% de correspondência no grande grupo com alunos de perfis variados, determinando as contribuições possíveis e positivas que correspondem satisfatoriamente ao objetivo da pesquisa.

A formação de professores e o desenvolvimento do pensamento computacional: um panorama de pesquisas no ensino de matemática nos anos iniciais do ensino fundamental
Authors: Pires Barreto de Souza Vasconcelos Sarah , Nascimento de Menezes Eliziete , Carvalho Brandao Jorge , Costa dos Santos Maria José
Published: February 2022

Resumo: O pensamento computacional (PC) pode estimular o uso de habilidades lógicas na resolução de problemas para o ensino de matemática quando os docentes são formados nessa temática. O objetivo deste artigo é apresentar uma visão geral dos estudos que abordam o pensamento computacional na formação docente e a sua utilização no ensino de matemática nos anos iniciais. Esta é uma pesquisa bibliográfica e como metodologia utilizamos a abordagem quali-quanti para produzir esta Revisão Sistemática da Literatura (RSL). Para a seleção e pesquisa dos trabalhos obtidos, operamos as seguintes bases de dados: Emerald Insight, Science Direct, Scopus e Springer Link. Constatamos poucas produções acerca do tema e que a maioria ocorre nos Estados Unidos. Identificou-se que as formações de professores utilizam ferramentas tecnológicas e que o uso do Scratch prevaleceu em boa parte dos estudos, bem como a programação em blocos. Os resultados apontam ainda que a maior parte dos processos formativos ocorrem de maneira presencial e não descreveram de forma clara os conteúdos curriculares que são abordados durante as formações. Observou-se, ainda, que para as formações não presenciais prevaleceu a utilização do ambiente virtual de aprendizagem Moodle, tanto no curso híbrido, como na capacitação totalmente a distância. Nosso estudo aponta a necessidade de mais pesquisas que apresentem indicadores que promovam efetivamente o aprendizado dos alunos após o processo de formação docente, assim como carências de trabalhos que abordem a formação profissional dos professores no âmbito do PC no ensino de matemática.

Resumo: Função é um tema relevante para o estudo de outros conteúdos matemáticos, assim como para o desenvolvimento de diversas áreas do conhecimento, porém os estudantes nem sempre o compreendem satisfatoriamente. Nesse contexto, promoveu-se uma pesquisa que investigou como uma proposta pedagógica baseada nos princípios do Pensamento Computacional e na Teoria da Aprendizagem Significativa pode contribuir para o estudo de Função no Ensino Médio. Neste artigo, tem-se por objetivo apresentar a análise dos resultados da experimentação dessa proposta, realizada com alunos da 1ª  série do Ensino Médio de uma Instituição Federal de Educação. Resumidamente, Pensamento Computacional é a aplicação de fundamentos da computação para planejamento e execução de estratégias, tendo em vista a solução de problemas. No estudo realizado, essas estratégias foram desenvolvidas com e sem o apoio de tecnologias digitais. A pesquisa delineou-se como qualitativa, do tipo Intervenção Pedagógica, ocorrendo em formato de curso extracurricular, realizado remotamente, devido à pandemia de COVID-19, com oito encontros síncronos. Os instrumentos de coleta de dados foram observação, questionários (inicial e final) e atividades (de sondagem conceitual, da terceira seção da apostila elaborada e final). Uma parte da análise de dados foi promovida com base no aporte teórico e a outra ocorreu por meio da metodologia Análise de Erros. Os resultados indicaram contribuições do uso do Pensamento Computacional de forma integrada ao currículo de Matemática, como proposto na Base Nacional Comum Curricular. Foram observados indícios de aprendizagem significativa em tópicos abordados e também melhorias na capacidade de resolução de problemas por parte dos alunos.

Oportunidades, escolhas e vocação: percursos na constituição do ‘ser professor’ de docentes bacharéis do ensino superior privado
Authors: Vieira da Silva Cavalcante Lígia , Feldens Schwertner Suzana
Published: February 2022

Resumo: O presente artigo apresenta os resultados de uma pesquisa realizada com professores bacharéis que atuam no ensino superior e tem como objetivo conhecer como se deu o percurso que conduziu esses profissionais à docência. Trata-se de pesquisa qualitativa, realizada por meio de entrevistas semiestruturadas com oito professores que atuam em uma Instituição de Ensino Superior da rede privada, no interior do estado do Ceará. As entrevistas foram analisadas através da proposta de Análise de Conteúdo. Os resultados apresentam, inicialmente, que as escolhas dos docentes pela área de formação aconteceram de forma aleatória ou por influência dos familiares. Contudo, no transcorrer da graduação conseguiram uma identificação com os cursos escolhidos e se sentem realizados com a sua atuação como professores. Relataram que, durante a graduação, as atividades de monitoria, pesquisa e identificação com determinadas disciplinas e professores os fizeram vislumbrar a docência como campo de atuação. Para que pudessem lecionar ou se sentirem mais preparados para o exercício da docência, trilharam alguns caminhos formativos a partir da graduação: cursar pós-graduação foi a escolha da maioria dos entrevistados. No entanto, referiram que as disciplinas das especializações e dos mestrados lhes trouxeram conhecimentos específicos de área, mas pouco contribuíram para a sua formação docente. Ao propor conhecer esta amostra de professores bacharéis, espera-se que o presente estudo contribua para a reflexão sobre a formação docente e indique caminhos para (re)pensar a prática profissional docente.

Published: February 2022

AIM: The goal of the study was to determine the trajectories of perinatal anxiety symptoms and their determinants among women who report with
risk anxiety during pregnancy and live in a low-resource context in Sriperumbuthur, Chennai.
Study Design: A Cross sectional study design
METHADOLOGY: This cross-sectional study included 192 women from Sriperumbuthur, a low-income neighborhood in Chennai, who were
selected at their rst prenatal visit if they scored 13 or higher on the Edinburgh Postnatal Anxiety Scale, were at least 18 years old, and were fewer
than 29 weeks pregnant. Participants were followed up on at eight months gestation, three months postpartum, and twelve months postpartum.
Growth mixture modelling was used to nd latent trajectories of anxiety symptoms based on the Hamilton Anxiety Scale (HAS). Because HAS
scores did not differ between the control and intervention groups, all individuals were evaluated jointly. Using health, social, and economic
variables of trajectories were studied to identify high-risk groups with more or more chronic rage symptoms.
RESULTS:There were two trajectories identied: prenatal alone (88%) with moderate to severe symptoms at baseline that subsequently diminish;
and antenatal and postnatal (12%) with severe anxiety symptoms during pregnancy and later in the postpartum period that subside to moderate
levels at 3 months postpartum. Severe food hardship, intimate partner violence, reduced social support, more functional impairment, problematic
drinking, and suicide risk are all predictors for the prenatal and postnatal trajectory.
CONCLUSION: A small percentage of women who are at risk for anxiety prenatally remain at risk during pregnancy and can be distinguished
from those who experience a spontaneous remission. These ndings should be included into identication and referral efforts, especially
considering the scarcity of mental health services in low-income areas.

<10% of all tumors of salivary glands, it is one of the most common (approximately 30%) of all malignant tumors of the salivary glands. It can be
classied histologically, into low, intermediate, and high grade and is composed of mucus, squamous, and intermediate types of cells. Most
frequently seen in parotid gland, followed by minor salivary glands. Treatment of MEC depends upon the extent and aggressiveness of the lesion.
Here we present a case of low grade mucoepidemoid carcinoma which involved both hard and soft palate also with palpable lymph node which was
treated with wide local excision and left infrastructural maxillectomy followed by repair with temporalis myofascial ap.
A STUDY OF PLATELET VOLUME PARAMETERS IN THROMBOCYTOPENIA CASES.
Authors: Tripathi Charu , Pawar Gaurav
Published: February 2022

Recent studies showed that platelet parameters such as mean platelet volume (MPV), plateletcrit (PCT), platelet size deviation width (PDW) could
be used for differential diagnosis of thrombocytopenia. In the present study, accordingly, we aimed to investigate the signicance of these
parameters in the differential diagnosis of thrombocytopenia. One hundred sixty-four (164) patients with thrombocytopenia were included in the
present study. The patients were divided into two groups according to the time of the diagnosis of thrombocytopenia: hyperdestructive (75 ITP) and
hypoproductive (25 AA, 25 MDS, 24 AML, 15 ALL). The diagnosis was made based on hematological, pathological, and chromosomal analyses
and guidelines. Samples for complete blood counts were collected in K3EDTA tubes and analyzed with an automated hematology analyzer,
Beckman-Coulter. The platelet count was similar in both groups. The present results showed that there were no statistically signicant differences
between the groups in terms of age, gender and PDW. However, MPV was signicantly higher in the hyperdestructive group than the
hypoproductive group. By contrast, PCT was considerably lower in the hyperdestructive group than the hypoproductive group The results of the
present study indicated that these platelet parameters might provide additional contributions to strengthen the diagnosis in patients diagnosed with
ITPand would be benecial to consider the thrombocyte parameters as well as the clinical and other laboratory tests of the patient

Authors: Patadia Jigisha , Patel Charmy , Shaikh Shahid
Published: February 2022

Background: Mucormycosis is a rare Angioinvasive, opportunistic fungal infection occurring most often in immunocompromised patients with
reported mortality rate of 95% in disseminated cases9. The most common clinical presentation of infection with the fungus is rhinocerebral,
followed by primary pulmonary, disseminated, gastrointestinal and cutaneous manifestations, whereas Renal Mucormycosis is a manifestation of
disseminated diseases(10,11). Since, isolated renal Mucormycosis is extremely rare, and there are only few case reports describing the isolated
renal Mucormycosis in literature. Clinical Description: We report a case of immunocompromised child with T cell ALL, presenting as high grade
fever with abdominal pain and respiratory distress, who underwent nephrectomy for renal gangrene, Histopathological examination of which
revealed mucormycosis and other relevant investigations suggestive of MISC. Management: Patient was initially managed with nephrectomy and
higher antibiotics, followed by IVamphotericin B, and IVIG for MISC, but later succumbed to illness. Conclusion:Ahigh index of suspicion with
multidisciplinary treatment approach involving early institution of pertinent antifungal therapy, addressing underlying other comorbidities, and,
where possible, surgical debridement of debilitate tissue is obligatory to achieve therapeutic success.
SPECHT: Self-tuning Plausibility Based Object Detection Enables Quantification of Conflict in Heterogeneous Multi-scale Microscopy
Authors: Cardoen Ben , Wong Timothy , Alan Parsa , Lee Sieun , Matsubara Joanne Aiko , Nabi Ivan Robert , Hamarneh Ghassan
Published: February 2022

We introduce a novel method that is able to localize fluorescent labelled objects in multi-scale 2D microscopy, and is robust to highly variable imaging conditions. Localized objects are then classified in a novel way using belief theory, requiring only the image level label. Each object is assigned a `belief' that describes how likely it is to appear in an image with a given set of labels. We apply our method successfully to identify amyloid-beta deposits, associated with Alzheimer's disease, and to discover caveolae and their modular components in superresolution microscpy. We illustrate how our approach allows the fusion or combination of models learned across markedly different datasets. We show how we can compute the `conflict', or disagreement between the models, an insight that can allow the domain expert to interpret the composite model.
Development and validation of comprehensive closed formulas for atmospheric delay and altimetry correction in ground-based GNSS-R
Authors: Nikolaidou Thalia , Santos Marcelo , Williams Simon , Geremia-Nievinski Felipe
Published: February 2022

Radio waves employed in Global Navigation
Satellite System Reflectometry (GNSS-R) are subject to atmospheric refraction,
even for ground-based tracking stations in applications such as coastal
sea-level altimetry. Although radio propagation atmospheric delays are best
investigated via raytracing, including reflections, such a procedure is not
trivial. We have developed simpler closed formulas to account for atmospheric
refraction in ground-based GNSS-R and validated them against raytracing. We
provide specific expressions for the linear and angular components of the
atmospheric interferometric delay and corresponding altimetry correction
components, parameterized in terms of refractivity and bending angle. Assessment
results showed excellent agreement for the angular component and good for the linear
one. For the conditions analyzed, about half of the delay was found to originate
above the receiving antenna, for satellites at low elevation angles. We define the
interferometric slant factor used to map interferometric zenithal delays to
individual satellites. We also provide an equivalent correction for the
effective satellite elevation angle such that the refraction effect is
nullified. Lastly, we present the limiting conditions for negligible atmospheric
altimetry correction (sub-cm), over domain of satellite elevation angle and
reflector height. For example, for 5-meter reflector height, observations below
20° elevation angle have more than 1-centimeter atmospheric altimetry error.
A Computationally Efficient Compact Model for Ferroelectric FinFETs Switching with Asymmetric Non-Periodic Input Signals

Published: February 2022

In this paper, we develop a Verilog-A implementable compact model for the dynamic switching of ferroelectric Fin-FETs (Fe-FinFETs) for asymmetric non-periodic input signals. We use the multi-domain Preisach Model to capture the saturated P-E loop of the ferroelectric capacitors. In addition to the saturation loop, we model the history dependent minor loop paths in the P-E by tracing input signals’ turning points. To capture the input signals’ turning points, we propose an R-C circuit based approach in this work. We calibrate our proposed model with the experimental data, and it accurately captures the history effect and minor loop paths of the ferroelectric capacitor. Furthermore, the elimination of storage of each turning point makes the proposed model computationally efficient compared with the previous implementations. We also demonstrate the unique electrical characteristics of Fe-FinFETs by integrating the developed compact model of Fe-Cap with the BSIM-CMG model of 7nm FinFET.
The Carbon Footprint of Machine Learning Training Will Plateau, Then Shrink

Published: February 2022

Machine Learning (ML) workloads have rapidly grown in importance, but raised concerns about their carbon footprint. Four best practices can reduce ML training energy by up to 100x and CO2 emissions up to 1000x. By following best practices, overall ML energy use (across research, development, and production) held steady at <15% of Google’s total energy use for the past three years. If the whole ML field were to adopt best practices, total carbon emissions from training would reduce. Hence, we recommend that ML papers include emissions explicitly to foster competition on more than just model quality. As estimates of emissions in papers that omitted them have been off 100x–100,000x, publishing emissions has the added benefit of ensuring accurate accounting. Given the importance of climate change, we must get the numbers right to make certain that we work on its biggest challenges.

Abstract:

Two recursive least-square (RLS) adaptive filtering algorithms are most often used in practice, the exponential and sliding (rectangular) window RLS algorithms. This popularity is mainly due to existence of low-complexity versions of these algorithms. However, these two windows are not always the best choice for identification of fast time-varying systems, when the identification performance is most important. In this paper, we show how RLS algorithms with arbitrary finite-length windows can be implemented at a complexity comparable to that of the exponential and sliding window RLS algorithms. Then, as an example, we show an improvement in the performance when using the proposed finite-window RLS algorithm with the Hanning window for identification of fast time-varying systems.

Comments on SIC design for SISO NOMA Systems over Doubly Selective Channels.
Authors: Kontorovich Valeri
Published: February 2022

Non-orthogonal multiple access principle applied
in power domain (power-domain NOMA) enhances spectrum efficiency and
connectivity of mobile communication systems through sharing between Orthogonal
Multiple Access (OMA) and other multiple users. It is the almost main current
trend for research and standards for 5G and beyond. Spectrum sharing generates
multi-users interference (Multiple Access Interference, MAI) which destroys
orthogonality in OMA systems. Meanwhile the so-called Successive Interference
Cancellation (SIC) techniques are used to suppress MAI and the Cognitive Radio
(CR) principle (CR-NOMA) for decoding order for multiple users inspired
effective SIC algorithms. The CR-NOMA principle is applied in the present
material as well, but with significant changes for SIC design as for Doubly Selective
channels. Due to the above reasons, two original SIC
design methods are proposed hereafter following the CR-NOMA principle.
Regarding to it the OMA signal (primary user) is decoded first using a
Chaos-based quasi-optimum Extended Kalman Filter (EKF). The set of “secondary
users” (multiusers) are proposed to be decoded secondly by the following two
different methods:

- Chaos-based EKF filters or ,

- Sequential m
hypothesis testing.

 The
proposed approach for SIC design is rather simple, fast and accurate for
practical implementation.
Optimal 3GPP Fairness Parameters in 5G NR Unlicensed (NR-U) and WiFi Coexistence

The fifth-generation networks, designed to provide
a better quality of service and spectrum utilization, are rapidly
being deployed across the world. 3GPP has proposed a fairness criterion, referred to as "3GPP fairness", for the coexistence of 5G New Radio in unlicensed spectrum (NR-U) and WiFi
in Release 16. In this correspondence, we derive an analytical expression to determine if the 3GPP fairness is achieved in a given
network configuration. We model achieving the 3GPP fairness
as an optimization problem and show how to use Sequential
Quadratic Programming to find the optimal 5G NR U parameters
from a pre-decided range. We test the optimizer in various
conditions and inspect the effect of various parameters. Our
results reveal that the optimizer is able to predict the best
possible parameters for 3GPP fairness and therefore the proposed
method proves useful for tuning 5G NR-U parameters during
their coexistence with WiFi.
Hechtingsstoornissen: Praktijkgericht therapiehandboek voor ernstige hechtingsstoornissen bij kinderen
Authors: Rygaard Niels P.
Published: February 2022

Hoe zijn hechtingsstoornissen aan hun symptomen te herkennen? Om welke behandeling vragen hechtingsgestoorde cliënten in de uiteenlopende fasen van persoonlijkheidsontwikkeling? En welke maatregelen zijn geboden om een gezonde hechting in de vroege kindertijd te waarborgen? In dit therapiehandboek worden deze vragen uitvoerig aan de orde gesteld. Naast theoretische kennis biedt de auteur vooral een grote hoeveelheid aanwijzingen voor de therapeutische praktijk. Elke stap gaat vergezeld van casusbesprekingen en checklists voor de behandelingspraktijk. Hoofdstukken over adoptie, aandachtsstoornissen en seksueel misbruik geven de lezer aanvullende handvatten voor de diagnose en behandeling in de eigen praktijk. Het multidisciplinaire therapiehandboek Hechtingsstoornissen is daarom onmisbaar voor professionals die werken met hechtingsgestoorde kinderen: psychologen, psychiaters, kinderartsen, pedagogen, sociaal werkers, therapeuten, pleegouders en leerkrachten.
Transformation of library and information services in terms of remote service
Authors: Smoliar Inessa , Turovska Lesia
Published: February 2022

The article addresses the problems faced by the modern library in remote reader service. By accumulating your own electronic information resources, forming electronic information products (ECs, DBs, electronic exhibitions, etc.) based on them, does the book collection ensure the completeness and quality of library information services? Topical domestic and foreign librarians, who are included in the source of their research, are taking care of this issue.
The article focuses on the work of the VNLU scientists, who trace the evolution of the scientific library as a component of the world information infrastructure and join the formation of a global information space by radically changing approaches to organizing library activity.
In analyzing library studies, the authors note the lack of a common point of view, divergence and lack of sound policy on the problems of online transformation of the library environment, and substantiate the need to identify and systematize all existing forms and methods of remote service and substantiate the need for their integration on a single methodological and methodological platform.
In terms of library practice, the authors highlight a number of existing contradictions between traditional and innovative forms and methods of library and information services. The levers of overcoming these contradictions, in their opinion, are the development of uniform methodological principles of library and information support in terms of remote service; conducting market research to gain an objective assessment of remote service performance from the perspective of key stakeholders — remote users; the construction of an algorithm, adaptive model and, finally, a slim system of library and information support for remote readers under remote service conditions.
How does a book live after buying: the results of the survey
Authors: Romaniuk Natalia
Published: February 2022

The results of the study about books' life after buying are described in the article. The main objective of the study is to reveal how readers use a book in consumer culture. We tried to answer such questions: if the novelty is important for our attitude to the book; for which necessities people buy books; if the book is an item for one-time use or it is reusable in fact; how often people use the home or public libraries etc.
221 people completed this questionnaire (65,6% — women, 34,4% — men). Three-quarters of respondents are under the age of 35, 19% — readers aged 36 to 50 years old, 5,5% — over 51. One part of the questions deals with buying books, other ones — with using them. According to the survey, 43% of readers buy used books, a little over a quarter don't do it, other readers sometimes can buy second-hand books. Almost half of the readers do not pay attention to whether the book is a novelty of the publishing house; half of the respondents are ready to buy a book published a few years ago if the topic is of interest. The majority choose fictional books for personal or professional development. Almost half of the respondents buy books as a gift (more often for children than for adults).
The questions about using books gave us the following results. Only about one-sixth of survey participants often borrow books from friends, while about 57% are willing to share their books with other people. More than half of respondents occasionally reread books stored at home, but 42% of people don't do this. Less than 15% of respondents are active users of public libraries. Most respondents prefer reading at home on the bed or the couch, almost 70% also like reading in transport. About half of the respondents make no mark in the books, the rest can emphasize, bookmark, perish corners, write comments, etc.
The results of the research can be used to study the behavior of buyers by publishing houses or bookstores, to design the publication, in the study of consumer culture in general, etc.
