Published: January 2023

Abstract Objectives to analyze the perceptions of the Quilombola population of Caldeirão about their health conditions and to identify the possibilities and difficulties in the relationship with the health services in their territory. Method a qualitative, descriptive and exploratory study, carried out in the Quilombola Community from Caldeirão, Marajó Island, Pará, Brazil. Data production took place from March to April 2021, through individual semi-structured interviews with 30 residents, and thematic content analysis was applied. Results two empirical categories originated, revealing the Quilombola population’s perceptions about their health conditions and the health-disease process, the relationship that the community had with the local health services and the strengths and weaknesses inherent to this relationship. Conclusions and implications for practice Quilombola people’s perceptions showed a predominance of biomedical knowledge and a hospital-centric view, in addition to their weakened relationship with local health services. It is expected that the research results will encourage dialogue about these populations, considering that they represent a traditional group in a vulnerable situation. It is necessary to carry out further research to investigate/strengthen the Family Health Strategy role and unveil/problematize traditional knowledge in the face of biomedical knowledge hegemony in the scenario of Quilombola populations.

Abstract Objective to analyze, in caregivers’ perception, the health care practices provided to Quilombola children. Method an exploratory-descriptive, qualitative study carried out in the Quilombola community Santa Rita de Barreira, São Miguel do Guamá, Pará, Brazil. Data were produced between July and September 2021, with caregivers of children aged zero to five years, through individual interviews guided with a semi-structured instrument. For analysis, Microsoft Office Excel 2019 and the Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires 0.7, alpha 2 were used, through Descending Hierarchical Classification. Results eighteen female caregivers participated, aged between 20 and 67 years. They related care to disease prevention and treatment, life habits, health services access and popular practices that value traditional medicine. Conclusions and implications for practice women’s knowledge and actions expressed influences from their culture, their beliefs and their ways of interpreting and symbolizing reality. Recognizing and questioning Quilombola practices in child care is a challenge that goes beyond the biomedical, reductionist and stigmatizing discourse, a context in which it is necessary to expand the interdisciplinary debate on the subject.

Authors: Francisco Renata Ribeiro
Published: January 2023

Resumo O presente artigo tem o objetivo de discutir a participação da maçonaria paulistana no processo abolicionista em São Paulo. O protagonismo maçônico sobre a agenda emancipacionista não se concretizou na cidade, ainda que a organização tenha reunido os principais nomes do abolicionismo local. A análise dos livros de atas das lojas maçônicas América e Piratininga e outros documentos evidencia as disputas internas e a fragmentação do discurso antiescravista neste espaço de sociabilidade, entre 1850 e 1888.

Methods qualitative and analytical, observational, cross-sectional, and prospective study, approved by Research Ethics Committee, 3.443.429/19, with volunteers with and without history of motion sickness who were subjected to immersion in VR with the use of virtual reality glasses. Before and after sensory stimulation, the participant had respiratory rate (RF), heart rate (HR) and systolic blood pressure (PAs) and diastolic blood pressure (PAd) measured. On the first day, the volunteer was exposed to a video that simulated a person in a car, with a predominance of lateral visual flow. A week later, an animation of a roller coaster, with a predominance of frontal visual flow. During the 10-minute experiment, a score from 0 to 10 was given every 30 seconds for the intensity of the discomfort felt by the volunteer. A post-questionnaire was conducted to assess motion sickness symptoms. Results individuals with motion sickness history had a higher intensity of symptoms in the car (p = 0.026) and roller coaster experiment (p = 0.035). There was no correlation between motion sickness and the variables HR,FR,PA. Patients with motion sickness gave higher scores of discomfort throughout the experiments, mainly in the roller coaster experience. Conclusion individuals with motion sickness present more intense symptoms when subjected to stimuli by VR compared to controls without disease.

Published: January 2023

Abstract Introduction Adapting to a child with Autism Spectrum Disorder (ASD) can impact the occupational performance of mothers because of the care they demand, which can lead to difficulties in carrying out their occupations. Objective To investigate the occupational performance and adaptation of mothers to their children with ASD. Method Cross-sectional, descriptive, quantitative and qualitative study conducted with 11 mothers of children with ASD aged 2-9 years. Data were collected using the Parental Disability Adaptation Scale (EPAD) and the Canadian Occupational Performance Measure (COPM). EPAD data were analyzed by adding the scores of each participant and calculating the general average, whereas COPM data were analyzed from the values assigned to performance and satisfaction. Results The mothers were well adapted to their children; however, they evaluated the presence of functional problems for occupational performance after their birth. Functional problems in the productivity category, specifically in work performance due to the demands of caring for the children, were mentioned by most mothers. In the self-care category, some mothers reported problems related to going to the salon and taking a shower. In the leisure category, some mothers indicated problems with reading, physical activity, traveling and/or visiting friends. Conclusion The mothers in this study reported that adapting to their children with ASD involves factors such as transmission of the diagnosis, information, children characteristics, socioeconomic conditions, resilience, and personal beliefs and expectations. In conclusion, the mothers of children with ASD investigated presented functional problems regarding their occupational performance after the birth of these children.

Conclusion Smoking is an occupation that needs to be considered during smoking cessation treatment, as how the occupational transition is addressed can interfere with treatment adherence.
DESVELANDO FORMAS ARBITRÁRIAS DE DOMINAÇÃO: O TRABALHO SOCIOLÓGICO DE PIERRE BOURDIEU
Authors: Catani Afrânio Mendes
Published: January 2023

RESUMO O texto procura, inicialmente, acompanhar a trajetória do sociólogo francês Pierre Bourdieu (1930–2002) ao longo de mais de quatro décadas, destacando suas atividades enquanto pesquisador e, também, como “agitprop” (“agitador profissional”). Num segundo momento, dedica-se a narrar minha experiência de trabalhar com os pressupostos teóricos desenvolvidos pelo autor em alguns campos do conhecimento. Conclui ressaltando que a leitura e a utilização de Bourdieu, vinte anos após sua morte, continua indispensável no sentido de desnaturalizar os mecanismos instituídos de ocultamento das relações que levam às divisões sociais.
A Saúde Coletiva e suas áreas: territórios ou aldeamentos?
Authors: Ayres José Ricardo de Carvalho Mesquita
Published: January 2023

A progressiva conformação de áreas específicas de conhecimento e prática no interior do campo da Saúde Coletiva brasileira tem desafiado sua unidade e sua identidade enquanto tal. Como compreender o movimento centrífugo de diferenciação dessas áreas desde sua origem comum? Como resgatar uma identidade de campo e criar sinergias entre as áreas? O presente ensaio busca refletir sobre essas questões tomando por base aportes teórico-filosóficos da hermenêutica contemporânea (Gadamer, Ricoeur, Habermas). Critica-se a noção de territorialidade epistemológica e, recorrendo a uma identidade normativo-proposicional oriunda da facticidade do social na saúde, propõe-se a noção de “aldeamento” para (re)construir a unidade do campo em sua pluralidade, indicando-se alguns movimentos com potencial de estimular esse processo.

O objetivo do presente estudo é analisar o conteúdo PC/AF por meio dos prontuários de teleconsultas e videoaulas do Núcleo de Telessaúde de Goiás. Trata-se de pesquisa exploratória, com abordagem qualitativa. Como resultado, foram identificados 180 prontuários e 23 videoaulas que tematizam conteúdos das PC/AF. A análise evidenciou teleconsultas mais frequentemente relacionadas ao treinamento físico, que buscavam a prevenção e controle de DCNT, e o esforço por parte de teleconsultores em apresentar elementos diversos da cultura corporal e da clínica ampliada, em conformidade com a Política Nacional de Promoção da Saúde.
População em situação de rua e Rede de Atenção Psicossocial: na corda bamba do cuidado
Authors: Paiva Irismar Karla Sarmento de , Guimarães Jacileide
Published: January 2023

Resumo A interface rua e saúde mental adensa vulnerabilidades, o que dificulta a garantia do direito à saúde. Obetivou-se analisar como se dá a atenção à saúde da População em Situação de Rua no âmbito da Rede de Atenção Psicossocial em Natal-RN. Pesquisa de campo, qualitativa descritivo-exploratória. Realizou-se grupo focal com 10 profissionais dessa rede e entrevista semiestruturada com 13 pessoas em situação de rua. Os resultados foram submetidos à análise de conteúdo temática, sistematizados em duas categorias: 1) A vida nua da População em Situação de Rua; 2) Os nós da rede e os fluxos de vida da População em Situação de Rua. Tem-se uma invisibilização da população em situação de rua ou uma associação a estigmas e rótulos. Delineia-se o espaço da rua de exceção, vida nua. Nessa condição, essas pessoas enfrentam inúmeras barreiras no acesso à rede no cenário estudado. Destacam-se inúmeros desafios da rede frente às dissonâncias de uma política que ao mesmo tempo que cuida, segrega, isola, tutela, cerca. Identificaram-se entraves que caminham na contramão da Reforma Psiquiátrica brasileira e potencialidades que favorecem sua efetivação resistindo na “corda bamba”.
Desnaturalizar a psicologia é preciso
Authors: BOARINI MARIA LUCIA
Published: January 2023

Resumo É expressiva a literatura sobre a história da psicologia, em geral, circunscrita ao seu caráter técnico e científico. Neste ensaio, temos como objetivo sair dos limites da história da psicologia para situar o lugar da psicologia na história. Ao sair destes limites, constatamos que, há séculos, conteúdos psicológicos foram objeto de reflexões que marcaram época, sem o caráter de profissionalismo. Isto quer dizer que a psicologia não é uma profissão por natureza, mas se fez profissão e ciência na sociabilidade burguesa. Como profissão, a psicologia busca a certeza, a precisão orientada pelos padrões da sociedade que a constituiu. Assim, o profissional psicólogo insiste no tecnicismo, no corretivo, orientado por sua concepção de homem e de sociedade que não leva em conta a complexidade da trama de relações sociais que envolvem o indivíduo e marca indelevelmente sua singularidade. Enquanto profissão, a psicologia é apenas uma parte do lugar que ocupa no transcorrer da história. Lembramos que “os segredos da alma” nem sempre se revelam pela precisão do saber científico, pelo profissionalismo, como atesta o saber psicológico de filósofos, escritores, poetas de distantes ou mesmo de épocas próximas.
Japanese imperial psychiatry in Tokyo: two Korean immigrants in a psychiatric hospital, 1920-1945
Authors: Suzuki Akihito
Published: January 2023

Abstract During the first half of the twentieth century, Western psychiatry was quickly absorbed in Japan, particularly the versions from Germany and Austria. By 1940, over 130 psychiatric hospitals were caring for approximately thirty thousand patients in cities, while in rural areas about sixty thousand people still depended on family members for care. Japan’s empire expanded during this same period, and many immigrants came to the country. Growth in immigration from Korea was particularly important. Korean immigrants encountered Japanese psychiatric hospitals during the second quarter of the twentieth century, and this paper examines the complex nature of their hospital stays.
A imigração no discurso médico-psiquiátrico brasileiro no pós-Segunda Guerra Mundial
Authors: Marques Guilherme dos Santos Cavotti , Carvalho Carolina da Costa de
Published: January 2023

Resumo O artigo analisa as contribuições da psiquiatria no debate sobre saúde e imigração no período pós-Segunda Guerra Mundial, quando o Brasil recebeu refugiados e deslocados de guerra vindos do Leste Europeu. A preocupação com desordens mentais atribuídas aos traumas de guerra tornava a saúde mental tema de debate na imprensa especializada. A partir da análise de artigos médicos publicados nas revistas Arquivos Brasileiros de Higiene Mental e Arquivos Brasileiros de Neuriatria e Psiquiatria e na Revista de Imigração e Colonização , busca-se compreender a relevância da imigração como um campo de atuação e disputa por legitimidade dos psiquiatras no papel de autoridades na elaboração das políticas imigratórias brasileiras.
Variação espaçotemporal de nutrientes inorgânicos dissolvidos e clorofila a em um estuário amazônico tropical no norte do Brasil
Authors: Santos Rosinette Machado , Sousa Pedro Henrique Campos , Varela Andrew Wallace Palheta , Pamplona Fábio Campos , Santos Maria de Lourdes Souza
Published: January 2023

Resumo O presente estudo foi desenvolvido no estuário do furo do Muriá ou Maripanema, localizado no setor Costa Atlântica do Salgado, norte do Brasil, com o objetivo de conhecer a dinâmica dos nutrientes dissolvidos na interface água-ar e os mecanismos de interação desses nutrientes com os parâmetros abióticos e bióticos (clorofila a). Esse sistema sofre a influência da sazonalidade, que envolve aspectos dos regimes de marés. Para tal, foi avaliada a variabilidade espacial e temporal dos nutrientes inorgânicos dissolvidos em conjunto com os parâmetros físico-químicos por meio de diagramas de mistura, razões estequiométricas e análise de componentes principais. O N-amoniacal foi a forma mais representativa de nitrogênio inorgânico dissolvido em ambas as estações com valores máximos de ~199 μM, subsidiando a produtividade primária, com valor máximo de clorofila a de 122 μg.m-3. O elevado nível de N-amoniacal esteve associado também ao lançamento de efluentes domésticos, à aquicultura e à degradação da matéria orgânica que ocorrem nas áreas de manguezais ao longo do furo do Muriá. O fosfato, entre os nutrientes dissolvidos, foi o que mais sofreu ação neutralizadora, com baixas concentrações, de forma a não oferecer sinais de eutrofização. As concentrações de sílica sofreram influência das variações de marés e fluxos das águas. No geral, os resultados obtidos permitiram observar uma entrada excessiva de nutrientes ao longo do furo do Muriá, com oscilações em suas concentrações influenciadas pela sazonalidade, pelas marés e pelas atividades antrópicas, indicando um ambiente altamente dinâmico que influencia diretamente a produtividade primária da região.
Influência da composição de agregado miúdo de rio e proveniente do processo de britagem em argamassas autoadensáveis
Authors: Duarte Geraldo Luís Becker , Silva Bruno José da , Martins Ben-HurRaíra , Casali Juliana Machado , Betioli Andrea Murillo
Published: January 2023

RESUMO O presente artigo teve como objetivo o estudo de argamassa autoadensável com composições de agregado miúdo (areia de rio e areia de britagem) com intuito de reduzir o consumo de areia natural de rio, uma vez que a mesma gera um impacto devido a sua extração. No estado fresco, as argamassas produzidas foram avaliadas quanto à densidade de massa, teor de ar incorporado, fluidez e análise de borda. No estado endurecido foram determinadas as resistências à tração e à compressão; o módulo de elasticidade dinâmico e a densidade de massa aparente. A partir dos resultados obtidos concluiu-se que a substituição de areia natural de rio por areia de britagem diminuiu a demanda de água nas argamassas autoadensáveis, resultando num aumento do consumo de cimento Portland por m3, em um menor volume de pasta para a mesma fluidez, isso devido ao maior módulo de finura da areia de britagem e melhor empacotamento em função da granulometria mais contínua. Com a diminuição da relação água/cimento houve um aumento dos valores de resistência à compressão e à tração e do módulo dinâmico, obtendo valores acima do mínimo exigido por norma. Como o consumo de cimento Portland por m3 também aumentou, evidencia-se a possibilidade de ajuste na composição reduzindo o seu consumo para uma dada resistência. Assim, com o aumento do teor de areia de britagem e de cimento Portland, as argamassas obtiveram um menor índice de intensidade de ligante, assim mais eficientes.

ABSTRACT The reuse of contaminated water arising from industries is a major challenge in the environmental field, which enables the search for treatments with a view to sustainable development. In this context, the objective of this study was to evaluate the effect of the calcination material from an ant colony (termite) in the production of adsorbent materials for methylene blue dye removal. The natural material (NC) and calcined materials at temperatures of 290ºC (C-290), 380ºC (C-380), 450ºC (C-450) and 540ºC (C-540) were characterized using techniques of thermal analysis and Fourier Transform Infrared Spectroscopy (FTIR). In NC and C-290 samples, the volatile compounds were evaluated by HS-GC/MS and phenolic compounds were identified by HPLC. The results for the adsorption of the dye methylene blue showed that, while the adsorption process can not be quantified employing the natural material, the process efficiency was quite relevant when the sample was calcined at a temperature of 290°C, whose removal percentage was 96%. Although the calcined sample at this temperature is the most similar to the starting material, performed at a temperature of 290°C acted in reducing the complexity of phenolic and volatile compounds found in the NC sample, which may negatively impact in the adsorption process.

Published: January 2023

RESUMO A busca por materiais na construção civil ecoeficientes pode ser realizada adicionando ou substituindo as matérias-primas por resíduos gerados em outros setores industriais. Muitos destes resíduos são classificados como perigosos, sendo que a inertização dos compostos que conferem periculosidade pode ser realizada através da estabilização por solidificação (E/S) que ocasiona o encapsulamento e a fixação química de substâncias tóxicas. No entanto, no Brasil não há uma norma regulamentada ou mesmo uma recomendação técnica, que seja específica para produtos E/S utilizados como componentes de construção. Neste contexto, o presente estudo teve como objetivo avaliar a lixiviação do cromo em matriz de concreto de cimento Portland pelos métodos de imersão e irrigação, com vistas ao emprego destes métodos na avaliação ambiental de materiais e componentes da construção civil. Para isso, foram confeccionados corpos de prova de 25x200x400 mm com e sem adição de 2% de Cr2O3 (óxido de cromo) em relação a massa do cimento Portland, os quais foram submetidos a testes de lixiviação por imersão e irrigação. Os resultados obtidos permitiram verificar o encapsulamento do cromo no concreto e que os testes de lixiviação propostos em monólitos de concreto, durante a fase de uso, mostraram-se aplicáveis em 28 dias.

Abstract: The objective of this work was to evaluate phytomass production, nutrient cycling, and efficiency of nutrient use by single and intercropped crop systems, in the second crop, under no-tillage. The experiment was carried out during the second crop of 2014 and 2015 in the Cerrado biome of the state of Mato Grosso, Brazil, in a randomized complete block design, with nine treatments and four replicates. In 2014, the systems were evaluated at 63, 93, 124, and 157 days after sowing; and, in 2015, they were evaluated at flowering and senescence. The concentrations of nitrogen, phosphorus, potassium, calcium, and magnesium were determined. In 2014, the single crop systems Urochloa ruziziensis, Cajanus cajan, and Pennisetum glaucum showed the largest accumulations of phytomass and nutrients. In 2015, the intercropped systems showed the largest accumulations of phytomass, the largest nutrient cycling, and the highest nutrient use efficiency. In the no-tillage crop systems, U. ruziziensis, either in single cultivation or intercropped with corn and sunflower, increased phytomass. The most efficient systems for the use of all nutrients, in the Cerrado of Mato Grosso, are the intercropping of sunflower with U. ruziziensis, corn with U. ruziziensis, and corn with Crotalaria spectabilis.
Reproducibility and Acceptability of Short Physical Function Tests Scores Obtained via Virtual versus Face-to-Face Assessments
Authors: Mehta Saurabh P. , Collier Paige A. , West Kaitlyn M. , Workmane Mollie C.
Published: January 2023

Gait speed (GS), 30-second chair stand test (CST), timed up and go test (TUG), and step test (ST) have been validated for face-to-face assessment (F2F) but not for virtual testing (VT). This study examined reproducibility and acceptability of GS, CST, TUG, and ST for VT. Three student physical therapists administered GS, CST, TUG, and ST to 52 healthy participants in F2F and VT formats. Participants' experience and acceptability of VT were captured via a survey. Reproducibility of these measures for VT was assessed using intraclass correlation coefficient (ICC), where ICC > 0.75 and > 0.90 indicated good and excellent reliability. Paired t-tests examined whether the scores differed in VT versus F2F. Interview responses were coded for convergence of information for acceptability of VT and audiovisual communication during VT. Scores for GS (ICC = 0.83), CST (ICC = 0.87), TUG (ICC = 0.95), and ST (ICC = 0.93) obtained in VT were reproducible with F2F. However, t-tests revealed that the VT scores were statistically different (P < 0.0001) for all measures, with exception of GS (P = 0.14), where performance was superior in F2F testing. Thematic analysis suggested high level of acceptability with VT but unanimous preference for F2F assessment. Results indicate that scores for GS, CST, TUG, and ST obtained via VT are reproducible with F2F, albeit superior performance was observed in F2F. Participants found VT acceptable but indicated preference for F2F.

The stability of graphene coatings deposited on substrates made of glass, single-crystal silicon with an oxide layer, and copper in contact with boiling water was experimentally tested. It was shown that multilayer graphene coatings are stable: they are not destroyed or peeled off from the substrates bound to them by van der Waals forces during boiling. However, when using a graphene coating obtained by the electric arc method, the adhesion of graphene films is not sufficient. Therefore, when boiling, they are destroyed. The technology of graphene coating synthesis and transfer proposed in this work can be used to create heating elements and heat-exchange devices based on graphene.

The invention discussed herein is a wideband rectangular microstrip patch antenna with customizable radiation patterns. Aside from the patch's resonant length, the antenna includes four symmetrically inverted U-slots and two coaxial probes. The antenna works in sum and difference modes in accordance with TM01 and TM02 modes, correspondingly. The microstrip patch antenna with U-slots offers a 68% impedance bandwidth, as well as stable polarization and symmetrical radiation patterns. The substrate thickness was very small, on the order of 0.02 d, where d is the wavelength of the dielectric medium at 3 GHz. To obtain broad bandwidth and symmetric radiation patterns, parameters are analyzed. The achieved null difference in difference mode is substantially below -30 db, making the suggested antenna ideal for monopulse radar applications. The antenna was found to be efficient in the frequency range 1.98-4.5 GHz. The antenna was designed using ANSYS HFSS software.
Synthesis of polycarboxylate superplasticiser modified by self-made functional monomer for improving clay tolerance
Authors: Wang Guangyang , Song Yuanming
Published: January 2023

Polycarboxylate superplasticisers (PCEs) are commonly sensitive to clay minerals. In this work, several clay-resistant PCEs (CR-PCEs) were synthesised using a novel self-made functional monomer (FM). The FM and the resulting superplasticisers were characterised by Fourier transform infrared spectrophotometry and gel permeation chromatography. The results showed that the CR-PCEs exhibited better dispersion performance than conventional PCE (C-PCE) in cement pastes containing montmorillonite (Mmt). The adsorption amount of the CR-PCEs on the Mmt was investigated using ultraviolet–visible spectrophotometry and it was found that the CR-PCEs had a lower clay sensitivity than the C-PCE. X-ray diffraction results of the Mmt revealed that the interlayer spacing of the Mmt treated with the CR-PCEs was lower than that of the Mmt treated with the C-PCE. It was thus concluded that the developed FM effectively improved the clay tolerance of the PCE.

Air-entrained wet shotcrete improves the pipeline transportation efficiency of concrete. The characteristics of the fine aggregate in the mix have different effects on the fluidity and mechanical properties of air-entrained wet shotcrete. The effects of four different properties of fine aggregates (mud content, sand ratio, water content and particle size) on the fluidity and mechanical properties of air-entrained wet shotcrete were studied, with particular attention paid to the sand ratio and mud content. The fluidity and mechanical properties of wet shotcrete were optimum when the sand ratio of the fine aggregate was 0.56 and the water content was 3%. The fine aggregate should have a reasonable particle size as far as possible. Montmorillonite in the mud inhibited the fluidity and mechanical properties, so mud content should be kept as low as possible. The results of this work provide a reference for the practical application of air-entrained wet shotcrete, so as to better deal with pipe blockage.

Published: January 2023

The biological purification of municipal wastewater as an organic waste with a low carbon (C)/nitrogen (N) ratio was explored in the presence of a carbon-rich lignocellulose substrate with a high carbon/nitrogen ratio in this study. The composition of the substrate was optimised to obtain the best biogas yield while maintaining reactor stability. The best composition was modelled and determined using response surface methods and mixture design. The findings revealed that anaerobic co-digestion of municipal wastewater with high-carbon/nitrogen-ratio substrates such as the sugarcane plant and wasted black tea improves biogas generation. This behaviour was observed in reactors with more than 70% (w/w) cane waste during testing in this study. Spent black tea as a co-substrate is suitable for co-digestion with municipal wastewater. However, due to the antibacterial properties of polyphenol and tannins in it, the presence of this substance at a high percentage in combination leads to the loss of useful microorganisms of anaerobic digestion and reduces the biogas production yield. The best substrate composition contains 25% (w/w) lignocellulose waste of sugarcane, 34% (w/w) spent black tea and 41% (w/w) municipal wastewater, which produced 239 ml/g volatile solids of biogas.

Published: January 2023

Decades of non-destructive evaluation (NDE) for the quality assurance of concrete bridges revealed the necessity of developing procedures for building reference specimens for different defects. External objects have been widely used in specimen construction to represent defects. However, embedded materials can alter the actual defect characteristics, interrupting the NDE responses. This study proposes new approaches to fabricating reference specimens for reinforced concrete that feature substantial defects, including cracks, delamination, honeycombing and rebar corrosion, without external objects. As a result, realistic responses can be acquired to identify promising NDE methods for characterising actual deteriorations. The procedures were produced with the intent of being reproducible in any laboratory. Destructive and non-destructive testing methods were performed to verify the effectiveness of the processes in creating defects. This study provides research laboratories with techniques for fabricating reference specimens for characterising defects and assessing the performance of NDE technologies.
Suppression of Leidenfrost instability using multiple rods and rectangular mesh elements

Published: January 2023

Large Leidenfrost drops may be unstable when their diameters exceed a critical value. Through theoretical and experimental investigations, this study explored the feasibility of suppressing Leidenfrost instability in a large container, by meshing the container or its central portion into rectangular elements. Thin rods were used to construct these rectangular elements. Leidenfrost instability was considered in four rectangular configurations. They were also the rectangular mesh elements that might be used. There were two findings. First, the diameter of the largest inscribed cylinder in a rectangular configuration was the critical dimension for determining Leidenfrost instability. Second, the threshold value of this diameter in a rectangular configuration with rod(s) was 8.9λ ± 0.7λ, where λ is the capillary length of water. It was larger than its counterparts in both a rectangular container (without the presence of a rod) and a circular container (with or without the presence of a rod), due to the strong effect of the rod in a rectangular configuration. Based on these two findings, a large rectangular container was meshed into rectangular elements using thin rods, with the diameter of the largest inscribed cylinder in each element below the threshold value. This mesh method suppressed the Leidenfrost instability in the large container.

In this study, the status of support and returns through the assistive technology device support project of the Korea Disabled Employment Agency was investigated, and the effect of employment retention period according to the type of assistive technology device was analyzed. In order to analyze the status of assistive technology device support and return status, the number and amount of assistive technology devices supported by the Korea Disabled Employment Agency from 2016 to 2019, and assistive technology devices returned by the disabled were analyzed by type. The difference in employment period by type was analyzed. In the case of the support status of assistive technology devices, the number of applications for commercial assistive technology devices is increasing, but customized assistive technology devices have been decreasing since 2017, and the amount of payments has increased sharply in 2019. Regarding the return status, from 2016 to 2019, the ratio of assistive technology devices under 1 million won was the largest at 56.0%, and the total amount of returned devices is increasing from 2018 to 2019. In the case of the employment maintenance period, 25.44 months were for disabled workers who received customized auxiliary engineering devices, longer than 24.91 months for disabled workers who received commercial assistive technology devices, which showed a statistically significant difference. This study investigated the support and return devices of the assistive technology device support project of the Korea Disabled Employment Agency, compared and analyzed the employment retention period of disabled workers according to commercial and customized devices. This study is the first study in Korea to analyze the effect of maintaining employment according to the type of assistive technology devices, and it is meaningful to support customized assistive technology devices for disabled workers, and it is hoped that the research results will provide a foundation for building a hub for integrated management of assistive technology.

This study is to suggest the direction of the 6th Comprehensive Policy Plan for the People with Disabilities. It presents policy goals and prioritized policy agendas based on the Interim and Final evaluation of the 5th Comprehensive Policy Plan for the People with Disabilities, the policy agenda developed for the 20th presidential election, and the Convention on the Rights of Persons with Disabilities of the UN and ILO, the Convention concerning Vocational Rehabilitation and Employment of the People with Disabilities, and the WHO's 2001 Disability Classification Table. As a result of the study, first, the policy goals of the 6th Comprehensive Policy Plan for the People with Disabilities were presented in the direction of inclusion rather than separation, and emphasizing fundamental rights rather than special measures, suggesting a society in which fundamental rights are guaranteed as a citizen. Second, the main tasks of the policy are classified into the areas of fundamental rights of the people with Disabilities, the area of disability sensitivity, and the area for removing barriers that hinder social inclusion of people with disabilities, and all central government departments and local governments, providing public services. It was suggested that it is necessary to design a system in which all public organizations participate. Third, as for detailed promotion tasks, a total of 25 areas were presented: 3 areas of basic rights, 3 areas of disability sensitivity, 9 areas of social participation, and 10 areas of continuous tasks.
