Tax policy reform for sustainable economic growth in Serbia
Authors: Ranđelović Saša
Published: March 2022

In the last two decades, the Serbian economy posted an average growth rate of 3.8 percent, which was above the average growth rate in the EU, Central and Eastern Europe (CEE) 1 and the Western Balkans 2 . Together with sharp decline in population, this has led to some economic convergence in terms of the GDP per capita, although the gap to the EU and CEE countries remains significant (57 and 42 percent respectively). To achieve full economic convergence with the European countries, Serbian economy needs to post long run growth rates of 4-6 percent per year, in a sustainable manner, which primarily refers to a more fair distribution of growth dividend (reduction of economic inequality) and limiting negative environmental footprint. In this sense, the reform of tax policy can make a contribution to the sustainable growth of the Serbian economy, through: i) a slight reduction in the overall tax burden, primarily through a significant cut in labour taxes, which may be financed by means of broadening the environmental taxes base, increase in consumption taxes and reducing unproductive public expenditures, ii) moderately increasing the progressivity of the personal income tax, recurring property tax and inheritance tax, and iii) broadening the environmental taxes base (with the focus on energy and pollution taxes) and introducing the tax incentives for households to switch to green energy sources.

Taste and nutritional value make sweet corn a valued plant and an important component of the human diet worldwide. Kernel nutritive composition of sweet corn has been reported in various papers, but a description of carotenoid and tocopherols profile, especially after cooking is scarce. Therefore, the present study was carried out to compare the carotenoid and tocopherol content in sweet corn before and after cooking. Contents of b-carotene, lutein+zeaxanthin and tocopherols (d-T, b+g-T, a-T) in the kernels of twelve sweet corn hybrids were determined by High-Performance Liquid Chromatography (HPLC) and were expressed as the mean value of three independent measurements. Both genotype and cooking affected the content of the carotenoids and tocopherols in the kernel. The highest content of total carotenoids before and after cooking was found in hybrid ZP486/1su (27.77/45.28 µg/g) whereas the lowest content was in hybrid ZP 355su (10.27 µg/g) before cooking i.e. in hybrid ZP 347su (24.55 µg/g) after cooking. The cooking resulted in a significant increase in the content of total carotenoids and tocopherols, lutein+zeaxanthin, and b-carotene in all hybrids, except the ZP504su in which the b-carotene content decreased. An increase in a-tocopherol after cooking was observed in hybrids ZP485/1su and ZP484/1su, while a decrease was in hybrids ZP481/1su, ZP486/1su and ZP477/2su. The results showed that increasing micronutrient content is genotype-dependent. This study confirmed that cooking increases the nutritional value of sweet corn and gives it additional value in terms of functional food.

Published: March 2022

To improve the pre-cracking behavior and post peak strength of concrete composites, a new variety of natural fiber called Fish Tail Palm Fibers was used as micro reinforcement in concrete. Fish Tail Palm Fibers (FTPF) are completely renewable natural resources and are available in abundance, in many parts of the country including India. Three different volume fractions, (0.1%, 0.2% and 0.3%, and three different lengths of fibers (10 mm, 20 mm and 30 mm) were chosen as the parameters for investigation. Silane treated FTPF was added to concrete and the fresh and mechanical properties were studied. The slump values were slightly affected by the increase in volume fraction of fibers, as the viscosity of concrete increases with fiber content. The compressive strength of the control specimen was 30 MPa (M30). The maximum compressive strength, splitting tensile strength, and flexural strength of Fish Tail Palm Fiber Reinforced Concrete (FTPFRC) specimens are 36 MPa, 2.82 MPa and 4.2 MPa respectively, which were recorded for specimens with 0.2 Volume Fraction (VF) and 30 mm Fiber Length (FL). The increase in the compressive strength, splitting tensile strength and flexure strength is about 20 %, 22% and 30 % with the addition of 0.2 VF of fibers. The findings indicate that the incorporation of fish tail palm fibers reduced the work-ability of concrete. But the mechanical characteristics such as compressive strength, splitting tensile strength, flexural strength, and impact resistance were enhanced with the increase in fiber content and fiber length.

Pheochromocytoma is a tumor that arises from adrenal medulla and it is characterized by increased secretion of catecholamines. The incidence of pheochromocytoma is 3 to 8 cases per million inhabitants, of which about 10 to 20% of diagnosed pheochromocytomas occurs in the pediatric population, with a higher frequency in boys. In 1.7% of the pediatric population with hypertension, the cause of hypertension is pheochromocytoma. Due to headaches and verified hypertension on twenty-four-hour holter blood pressure monitoring, the 13-year-old female patient underwent ultrasound, followed by scintigraphy and magnetic resonance imaging of the abdomen, which described an oval change above the right kidney about 4.5 cm in diameter suspected of pheochromocytoma. Twenty-four-hour urine cateholamines showed elevated noradrenaline values as much as 45 times higher than the reference range, as well as elevated Dopamine values. After adequate preparation with phenoxybenzamine and bisoprolol for two weeks, a right laparoscopic adrenalectomy was performed at the University Children's Clinic in Tirsova, which is also the first operation of this type in the pediatric population. Intraoperatively, the maximum value of tension was 180/120 mmHg. Pathohistological findings confirmed pheochromocytoma. Although a rare cause of hypertension in the pediatric population, young patients with newly diagnosed hypertension should be examined for possible pheochromocytoma. Laparoscopic adrenalectomy through both the lateral transabdominal and posterior retroperitoneoscopic approach is the gold standard for the treatment of pheochromocytomas in both the adult and pediatric populations.

Published: March 2022

Experimental verification of base-bleed effects on aerodynamic characteristics for the supersonic flight stages was requested during the development of an axi-symmetric projectile. The experimental setup for testing base-bleed configurations of the projectile was designed, built and tested in the T-38 trisonic blowdown wind tunnel of the Military Technical Institute (VTI), Belgrade. Gas-generator was formed from a simple chamber with a single manifold pneumatically connected to a high-pressure air supply. Wind tunnel tests comprised measurement of aerodynamic forces and moments of the projectile with active base-bleed. Flow visualization was performed using the Schlieren method. It was of interest to verify the base drag reduction in the wind tunnel tests and to compare it with numerical predictions. In addition, the experience gained during these tests has been found to be helpful in the design of the future similar wind tunnel setups

Published: March 2022

Free transverse vibration of a Rayleigh double-beam system with the effect of compressive axial load with a Keer layer in-between is studied in this paper. It is assumed that the two beams of the system are continuously joined by the Keer layer. The equations of the motion for this system are described by a set of three homogenous differential equations. The classic Bernoulli-Fourier method was used for solving this system of differential equations. In the research found in literature on the subject of the Keer model, the most common methods used are the theories of Timoshenko and Euler-Bernoulli. It is for that exact reason that the research goal of this paper is determining analytical and numerical characteristics (natural frequency, associated amplitude ratio) of the considered model by applying the Rayleigh theory. What is also researched is the effect of elastic in-between layer on system's frequency and amplitudes. The numerical analysis of the system was performed using software tools. The numerical results obtained are shown in the form of a plot diagram. Presented numerical results in this paper confirm those obtained in the literature.

Análise da interação de uma fonte pontual de lançamento de esgoto sanitário com a qualidade da água de um sistema lótico, Rio do Peixe, Santa Catarina, Brasil
Authors: Campos Roger Francisco Ferreira de , Kuhn Daiane Cristine
Published: March 2022

O lançamento irregular e silencioso de esgoto doméstico nos sistemas hídricos traz inúmeras consequências para a qualidade da água como o aumento das concentrações de matéria orgânica e nutrientes, proliferação excessiva de bactérias e redução do oxigênio dissolvido, dificultando assim o tratamento da água para abastecimento. Neste sentido, o presente trabalho tem como objetivo de avaliar a interação da água de tubulação com a qualidade da água do Rio do Peixe, por meio de quatro pontos amostrais na área do município de Caçador/SC. Para o desenvolvimento do trabalho foram determinados quatro pontos de coleta, sendo o ponto de coleta 01 a montante do local de afluência de uma tubulação de drenagem pluvial (50m), ponto 02 local de afluência da tubulação, ponto 03 a jusante da tubulação (50m) e ponto 04 a jusante da tubulação (100m). Os parâmetros analisados foram pH, temperatura, condutividade elétrica, turbidez, ortofosfato e fósforo total. Os resultados foram comparados aos padrões de qualidade da água estabelecidos na Resolução CONAMA 430/2011. Com os resultados obtidos, foi possível observar a maior concentração de fósforo total, ortofosfato, condutividade elétrica no ponto de coleta 02, que corresponde ao local de afluência da tubulação de drenagem pluvial com o Rio do Peixe. A média da concentração de fósforo total na amostra de água coletada no ponto 02, de 6,17 mg.L-1, está muito acima do padrão de qualidade da água estabelecido em legislação e demonstra a ocorrência do lançamento de efluente doméstico no Rio do Peixe. Sendo assim, é de estrema importância o monitoramento da qualidade da água do Rio do Peixe, para monitorar as fontes pontuais e difusa de lançamento de esgoto e efluentes industriais.

Published: March 2022

A gestão ambiental passou a se configurar como uma vantagem competitiva para as empresas, em vez de ser apenas uma forma de cumprimento de determinações legais, pois possibilita o desenvolvimento sustentável que busca conciliar crescimento econômico, preservação ambiental e responsabilidade social para que a sociedade possa ter condições de satisfazer as suas necessidades de subsistência. Neste âmbito, cita-se a Contabilidade Ambiental que se trata de um instrumento indubitavelmente relevante para o fornecimento de informações para a tomada de decisões gerenciais, balizadas a partir das demonstrações contábeis e legislação ambiental vigente. Considerando este contexto, este estudo buscou como objetivo principal entender e descrever como uma indústria de laticínios aplica a contabilidade ambiental. Para isso realizou uma pesquisa de abordagem qualitativa do tipo estudo de caso em uma Indústria de Laticínios localizada na região Sul de Minas Gerais. Foram entrevistados a Administradora da empresa por possuir as informações financeiras e contábeis e o Técnico de Produção que possui o conhecimento acerca dos processos de produção. Os relatos obtidos foram analisados por meio da técnica de codificação. Ao final, constatou que o laticínio investigado não aplica a Contabilidade Ambiental, adotando apenas ações paliativas como a terceirização da retirada do soro. Acredita-se ainda, que este cenário deve-se ao desconhecimento dos benefícios da Contabilidade Ambiental, pois muitas empresas visualizam esta ciência e seus métodos como mais um custo e não como um investimento que poderá gerar retorno significativo.

Um dos problemas ambientais decorrentes do processo de urbanização é a disposição final de resíduos sólidos. Em localidades como a Vila de Caratateua, município de Curuçá (PA), a falta de gestão voltada aos resíduos é preocupante, uma vez que a vila é cercada pelo Rio Caratateua. Nesse contexto, este artigo objetivou analisar a percepção ambiental dos moradores da comunidade local, em relação a geração, destino e consequências ambientais decorrentes do manejo de resíduos sólidos. Os resultados foram obtidos por meio de questionários aplicados à população local e expostos por meio de gráficos obtidos pelo software Excel e mapas temáticos, de modo a ilustrar a realidade da área de estudo. Verificou-se que os moradores da comunidade possuem conhecimento empírico em relação a conceitos ambientais, contudo, apesar da implantação de coleta regular, implantada somente no ano de 2018, uma parte da comunidade ainda destina de forma inadequada seus resíduos, através da queima e/ou despejando-os em rios e córregos. Nesse sentido, é necessário que, além da implantação de políticas públicas locais para gerenciamento de resíduos, sejam aplicados ações e programas que causem a sensibilização ambiental nos moradores da Vila de Caratateua.

Published: March 2022

A coleta seletiva é um instrumento da Política Nacional de Resíduos Sólidos, no qual se destaca a atuação de catadores de materiais recicláveis. Entretanto, os municípios de pequeno porte possuem dificuldade para sua implementação. Nesse sentido, faz-se mister que esses municípios tracem estratégias para desenvolver o referido serviço ambiental. O Plano Estadual de Resíduos Sólidos do Ceará estimula a formação de consórcios públicos, implantação de coleta seletiva e inclusão de catadores de materiais recicláveis. Desta feita, o presente estudo objetiva analisar a implantação da coleta seletiva no município de Tabuleiro do Norte, no Estado do Ceará, Nordeste do Brasil, no período compreendido entre 2018 e 2020, mediante entrevista aos gestores e pesquisa documental. Dos resultados, destaca-se que mais de 116 toneladas de resíduos com potencial reciclável foram recolhidas e comercializadas, com evolução entre os anos, mas correspondendo ao potencial de geração de resíduos de menos de duas semanas da área abrangida. Logo, há desafios a serem superados, que vão desde a mobilização e engajamento comunitário, agregação de valor à massa comercializada e fortalecimento da identidade e pertencimento dos catadores atuantes no município à associação local.

O Brasil possui legislações ambientais bem definidas quanto à classificação dos tipos de resíduos e quanto aos critérios de gerenciamento de Resíduos de Serviços de Saúde (RSS) que compreende as etapas de segregação, acondicionamento, armazenamento, destinação, transporte e disposição. Dessa forma, o trabalho tem como objetivo diagnosticar e analisar a percepção dos funcionários que atuam na Unidade de Saúde Central no município de Fraiburgo, Santa Catarina, Brasil. A metodologia utilizada se caracterizou com a aplicação de um questionário semiestruturado para os funcionários da Unidade de Saúde. As variáveis para análise estão relacionadas com várias questões referentes aos RSS, envolvendo classe dos resíduos, destinação, descarte – sendo composta por 10 variáveis. Verificou-se que existem funcionários dos serviços de saúde que desconhecem a classificação e o manejo correto destes resíduos. A partir deste estudo, observou-se a importância de desenvolver instruções de trabalho para evitar a falta de informação, orientando e padronizando as ações de manejo que envolvem os RSS e assim evitar contaminações no meio ambiente e principalmente com o ser humano.

Entretanto, ele veio reforçar a necessidade de inserir profundamente no ensino regular o conhecimento voltado para a energia renovável, e a sua importância nos dias atuais. O presente artigo, também, tem como objetivo final mostrar que o desenvolvimento de um minicurso com ênfase em energia solar, para atender a comunidade escolar, estará visando estimular o conhecimento e o interesse de todas as pessoas envolvidas nesta modalidade e forma de geração de energia. Para isso, terá que ser feito um plano desenvolvido, ou seja, uma capacitação dos educadores que ministram as matérias correlatas com o tema, bem como no futuro uma criação do curso e sua implementação definitiva na escola. Além disso, terá que ser implementado um arranjo prático na escola, através da instalação de um sistema solar simples e um bebedouro suprido por energia solar. Portanto, é a partir de todo esse contexto, que se espera o desenvolvimento e o interesse da comunidade escolar a respeito do tema “energia renovável”, fazendo parte do cotidiano de todos os docentes e discentes, com o objetivo fundamental de auxiliar nos dias atuais.
Merjenje tlakov plevralnega prostora med razbremenilno punkcijo (plevralna manometrija) kot varna in objektivna metoda pri ocenjevanju vpliva plevralnega izliva na izražanje simptomov
Authors: Meglič Anita , Adamič Katja , Dimitrić Vladimir , Nikolić Vesna , Rozman Aleš , Marc Malovrh Mateja
Published: March 2022

Izhodišča: Bolniki s plevralnim izlivom pogosto potrebujejo razbremenilno plevralno punkcijo (RPP), po kateri navajajo bolj ali manj izrazito olajšanje dispneje. Zaradi varnosti se priporoča, da se med RPP odstrani do 1.500 mL tekočine.

Metode: V raziskavo smo vključili 96 bolnikov, pri katerih je bila potrebna RPP. Zbirali smo ocene stopnje dispneje na lestvici VAS pred, takoj po in 2 uri po RPP, pri 73 bolnikih pa še 24 ur po RPP ter beležili količino odstranjene tekočine. Med RPP smo z vodnim manometrom merili plevralne tlake, iz katerih smo izračunali elastanco plevralnega prostora in na podlagi meritev bolnike razdelili v skupine z različnimi elastančnimi krivuljami.

Rezultati: Med začetnim plevralnim tlakom in količino odstranjene tekočine ter olajšanjem dispneje po opravljeni RPP smo ugotovili statistično značilno povezanost. Pri največjem deležu bolnikov smo RPP zaključili zaradi pojava simptomov, zaradi meritev plevralnega tlaka pa smo RPP prekinili pri 16 bolnikih (16,7 %). V skupino z normalno elastančno krivuljo smo uvrstili 74 bolnikov, nezmožnost razpenjanja pljuč pa smo ugotovili pri 22 bolnikih. Med RPP ni bilo pomembnih zapletov, kljub temu da smo več kot 1.500 mL izliva odstranili pri 32 (33 %) bolnikih.

Zaključek: Višji začetni plevralni tlak je šibko povezan z višjo začetno stopnjo dispneje in večjim olajšanjem dispneje po opravljeni RPP. Najbolj uporabna je dinamika sprememb plevralnega tlaka, s katero lahko že med RPP prepoznamo nezmožnost razpenjanja pljuč. Med RPP s plevralno manometrijo lahko varno odstranimo tudi več kot 1.500 mL tekočine.

Authors: KAYA Seher , OZEL BEKTAS Ozden
Published: March 2022

Objective: The aim of this study is to investigate the effect of a high concentration hydrogen peroxide bleaching agent on the surface roughness of four different composite resins.
Material and Methods: For this purpose, with the help of teflon molds, a total of 24 composite samples (10 x 2 mm) were prepared, with n = 6 for each composite group. The samples were placed in teflon molds in two layers of 2mm and covered by transparent mylar strips at the top and bottom surfaces. The material was compressed with finger pressure between 1mm thick glass plates. The tip of the light device was applied directly from the transparent tape surface for the polymerization of the samples. Polymerization of the samples was carried out using LED light device in each layer. After the samples were polished with finishing discs, they were kept at 37 ° C for 24 hours in the distilled water. Surface roughness values (Ra) of all samples were measured with a profilometer device. After the first measurements, a whitening agent containing 35% hydrogen peroxide was applied to the surfaces, and surface roughness measurements were repeated after this process. Data were analyzed statistically using analysis of variance (ANOVA) and Tukey tests.
Results: Profilometric evaluations showed a small increase in the surface roughness of all samples with a bleaching agent. When the initial and treated measurements of the groups were compared, the difference between the measurements was found statistically insignificant. (P> 0.05)
Conclusion: The office bleaching agent containing 35% hydrogen peroxide did not make any difference in the roughness of the nanohybrid and microhybrid composite resins.
KNOWLEDGE LEVELS AND ATTITUDES OF INTERNISTS ABOUT THE RELATIONSHIP BETWEEN PERIODONTAL DISEASE AND DIABETES
Authors: PİRİM GÖRGÜN Emine , YURTTAŞ M. Reyyan
Published: March 2022

AIMS: Periodontitis is a multifactorial, chronic inflammatory disease that can cause irreversible damage to the supporting tissues surrounding the teeth and consequently tooth loss if left untreated, and has been listed as the sixth major complication of diabetic patients. The aim of our study was to evaluate the knowledge levels and attitudes of internists about the relationship between periodontal disease and diabetes.
METHODS: In our study, our questionnaire with 22 questions was applied to internists via whatsapp®, e-mail and directly. Participants were asked about specific periodontal complications that they believed patients diagnosed with diabetes were more susceptible to, and their awareness of the bidirectional relationship between diabetes and periodontal diseases was evaluated. 112 internists answered (45% male, 55% female) our questionnaire.
RESULTS: 70% of the internists participating in our survey are between the ages of 25-35. 92.7% of internists know that the department that diagnoses and treats gingival diseases is the periodontology clinic. Despite this, only 72.7% refer their patients with gingival bleeding to the periodontology clinic. 58.4% of internists reported that they did not learn about the relationship between periodontal disease and systemic health during medical school education, and 89% stated that the effect of periodontal disease on systemic health should be explained in medical school education.
CONCLUSIONS: Periodontal disease and diabetes are thought to share a common pathogenesis that includes increased inflammatory response at local and systemic levels, and it is known that there is a bidirectional relationship. Therefore, successful treatment of both will affect each other positively. It has been observed that internists have knowledge about diabetes and periodontal disease in Turkey, but it is thought that it would be beneficial to consider the relationship between diabetes and periodontal disease in more detail within the education program of the medical faculty.
Effect of Composite or Ceramic Thickness on the Polymerization Hardness of 5 Different Dual-cured Resin Luting Cements
Authors: ATEŞ Gül , HERSEK Nur
Published: March 2022

Objective: The aim of the present study was to evaluate the influence of ceramic and composite thickness on polymerization hardness of five different dual-cure resin cements.
Materials and Methods: A total of 100 disc-shaped spacer, 10-mm in diameter and five varying thicknesses (1.0mm, 2.0mm, 3.0mm, 4.0mm, 5.0mm) were fabricated from ceramic and composite materials. Dual-cure resin cement specimens with 8-mm diameter were prepared using metal brass mold and activated by light beneath the composite and ceramic disc shaped spacers. A total of 100 specimens of five different dual-cure resins (RelyX, Variolink, NX3, Calibra, Panavia F2.0) were prepared. Knoop hardness of each dual-cure resin cement was measured at five different point using a microhardness device with a 500 gm load, after 1 hr, 1 day, and 1 week polymerization. All data were statistically evaluated using one-way ANOVA.
Results: Multivariate analysis of variance revealed significant differences in hardness of specimens dual-cured under composite resin or ceramic spacers and different time intervals (P<.001). Specimens cured through composite resin spacers showed less hardness values than ceramic spacers, with increasing thickness of the spacer. Also increasing the thickness of the composite or ceramic spacers produced a statistically significant decrease in microhardness of the dual-cure cements (P<.05).
Conclusions: Hardness values significantly reduced when composite spacers were thicker than 2 mm and ceramic spacers thicker than 3 mm. Dual-cured resin cements are needed to be improved to achieve sufficient degree of hardening under composite and ceramic restorations. Different commercially available brands have different polymerization properties.

Published: March 2022

Abstract
Objectives: This in vitro study was purposed to examine the effects of incorporation nano-ZrO2 on antibiofilm activity, glucose sorption, weight change, and surface roughness of two different types of denture liners.
Materials and Methods: Modified nano-ZrO2 were added to silicone-based and acrylic resin-based prosthetic lining materials at two different concentrations (0.5% and 1%). The antibiofilm potentials of test groups against Candida albicans (C. albicans), Staphylococcus aureus (S. aureus), and Streptococcus mutans (S. mutans) were determined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) method. Surface roughness, weight change, and glucose sorption of denture liners were also evaluated after modifying with nano-ZrO2.
Results: According to the antibiofilm activity results, 1% nano-ZrO2 addition to silicon-based and acrylic resin-based denture liners resulted in 16.48% and 13.39% of biofilm inhibition for S. aureus, respectively. 1% nano-ZrO2 addition to silicon-based denture liners also inhibited the S. mutans biofilm formation at an 8.16% rate. Nano-ZrO2 addition to the test groups had no inhibition effect on C. albicans biofilm formation. Surface roughness decreased significantly once nano-ZrO2 was added in tissue conditioner test groups (p=0.012), however, the addition of 0.5% nano-ZrO2 increased soft denture liner test group significantly (p<0.001).
Conclusions: To overcome the microbial biofilm problems (especially against S. aureus and S. mutans) caused by the use of denture liners, addition of nano-ZrO2 might be a promising agent with its antibiofilm capacities.

Ion trap system is one of the main quantum systems to realize quantum computation and simulation. Various ion trap research groups worldwide jointly drive the continuous enrichment of ion trap structures, and develop a series of high-performance three-dimensional ion trap, two-dimensional ion trap chip, and ion traps with integrated components. The structure of ion trap is gradually developing towards miniaturization, high-optical-access and integration, and is demonstrating its outstanding ability in quantum control. Ion traps are able to trap increasingly more ions and precisely manipulate the quantum state of the system. In this review, we will summarize the evolution history of the ion trap structures in the past few decades, as well as the latest advances of trapped-ion-based quantum computation and simulation. Here we present a selection of representative examples of trap structures. We will summarize the progresses in the processing technology, robustness and versatility of ion traps, and make prospects for the realization of scalable quantum computation and simulation based on ion trap system.

A análise retórica é o referencial metodológico adotado para o estudo do discurso mironiano, com destaque para o uso da metáfora do cultivo. Os resultados mostram a criação como processo que envolve o encontro com a natureza e a cultura, as trocas dialógicas, a problematização e a investigação. A recontextualização do conceito mironiano de criação nas discussões sobre formação de professores e sobre profissionalidade enseja o desenvolvimento de uma docência pedagógico-artística, criativa, erigida em meio à unidade estética, entre trocas decorosas e kairóticas, possibilitando questionamentos, reflexões e transformações.

Published: March 2022

O presente artigo tem o objetivo de discutir a formação profissional do pedagogo nos cursos de licenciatura em Pedagogia para o emprego das tecnologias educacionais. A coleta de dados foi realizada nas matrizes curriculares e na aplicação de questionários para professores e estudantes dos cursos. Os resultados apontam que mesmo os cursos oferecendo uma disciplina para a discussão das tecnologias educacionais, essa é insuficiente para promover uma formação sólida do pedagogo. Os professores formadores também manifestaram deficiência na oferta de materiais, na estrutura da universidade e na formação para que estes introduzam as tecnologias em suas aulas. Dessa forma, os acadêmicos sentem-se inseguros em trabalhar com elas na sua atuação docente, pelas poucas vezes em que tiveram contato com a teoria e a prática acerca da temática.

Published: March 2022

Este artigo tem como objetivo analisar o projeto de escolarização feminina desenvolvido e implementado pela Escola Doméstica, instituição de ensino doméstico localizada na cidade do Natal. Dessa maneira, foram analisadas duas fontes, O Programa Geral de Ensino (1911) e o Discurso Inaugural (1914), para compreender o funcionamento dessa escola como um dispositivo de controle e disciplinarização da feminilidade por meio de uma análise do discurso de inspiração Foucaultiana. Nesse sentido, foi possível perceber como esse projeto idealizava construir uma feminilidade condizente com os valores burgueses da modernidade, pautados em um ideal de “aperfeiçoamento da dona de casa”, tornando-a racionalizada e visando produzir novas sensibilidades.

Igueben is located in the central of Edo State, Nigeria. It has neighboring towns; Ogwa, Ugbegun, Ugiogba, Ebelle, and Ekpon. These towns have the same aquifer but significantvariations in the water table. However this study is intended to unravel the salient ancient hydrological processes that occurred in the study area which resulted in this variation. Vertical electrical sounding (VES) data and borehole data of the area are integrated to generate geo-electrical resistivity section of the area, to identify the aquifer trends, body, and shape to re-construct the palaeo-sedimentation processes of the aquifers that underlie Iguebe and the neighboring towns. The inversion model result for the seven VES conducted in the study area show that the curve types are HQA, AHA, A, AHA, AHA, HAQ, and AQA, respectively. These curve type suggested that the aquifer type is anarenite sandstoneaquifer that has been transported from a long distance. The geo-electrical pattern and shape show that Igueben and Ogwa (shallow marine) are the points of deposition from where other nearby towns (Ugbegun, Ugiogba, Ebelle, and Ekpon) sourced their aquifer by gravity settling from suspended sediments in water body into adjacent deep marine environment (Ugbegun, Ugiogba, Ebelle, and Ekpon).The study showed that Igueben and Ogwa are the hydraulic-head of the aquifer in the study area. The geological processes that had occurred in the study area during sedimentation are responsible for the variation in the water table in the study area.

Food insecurity has remained a major challenge to many developing countries. The Food and Agricultural Organization, estimates that 842 million people have suffered from lack of food access, resulting in undernourishment. Kenya’s rural and urban areas, have been suffering from food insecurity since independence. Previous case-studies have shown that, although various governments and donor agencies' have attempted to sponsor food-production programs, execution has remained a challenge. Elgeyo Marakwet has previously been experiencing famine intervention projects from World Vision Kenya, Community Agricultural Development for Semi-Arid Lands, National Agriculture and Livestock Extension Program and Njaa Marufuku Kenya.  The aim of this research was to examine the, organizational structure, socio-economic and capacity-building factors that contribute to sustainable food production in semi-arid and arid areas. The study used a descriptive survey research design to guide in the collection of data from a sample of 136 households using structured questionnaire. Data was analysed through cross-tabulation using Chi-square, ANOVA and percentages. In conclusion the research has revealed that organizational, demographic and capacity building factors are important in the improvement of food production. It is recommended that sustainable food security depends on developing sustainable local food production policy.

Published: March 2022

Aims: The inhibitory effects of 30 kinds of mushrooms, Chinese Herbs, and plant essential oils on Propionibacterium acnes (P. acnes) were compared to screen high activity antibacterial materials. Furthermore, their minimum inhibitory concentration (MIC), antioxidant activity, total flavonoids, and total phenol content were determined.

Methodology: The optimal antibacterial samples were screened using the paper diffusion method. The MIC was determined using the microdilution method. The antioxidant activity was evaluated by the 1,1-Diphenyl-2-Trinitrophenylhydrazine (DPPH), Ferric Ion Reducing Antioxidant Power (FRAP), and 2, 2'-Azino-Bis(3-Ethylbenzothiazoline-6-Sulfonic Acid) (ABTS) methods, and the total flavonoids and total phenol contents were determined using Rutin Method and Folin-Ciocalteu Method.

Results: The MIC of mushroom Tricholoma quercicola and Boletus edulis's extracts were 0.391mg/mL and 3.125mg/mL, showing better antibacterial effects on P. acnes. The Chinese herbs Pericarpium granati and Folium artemisia argyi's extracts (MIC 3.13mg/mL), plant essential oils of Eugenia caryophyllus flower, and Lavandula angustifolia (MIC 61.76mg/mL and 112.7mg/mL) exhibited satisfactory antibacterial effects on P. acnes. Antioxidant evaluation of the above six samples with high antibacterial activity revealed that Folium artemisiae argyi and Pericarpium granati's extract had good antioxidant activity. In addition, the determination results of total flavonoids and total phenols were consistent with the antioxidant activity.

Conclusion: The above results showed that Boletus edulis, Tricholoma quercicola, Pericarpium granati, and Folium artemisiae argyi could be used as candidate materials for the antibacterial, antioxidant materials, providing a feasible idea for the development of subsequent skincare products for the treatment of P. acnes.

Water is one of the most important commodity, which is essentially required for the survival of all types of life, including sustenance of ecosystems and bio-diversities. Human wellbeing hinges around availability of sufficient qualitative and quantitative water affordability for a quality life. People need to live and survive that’s why they must be aware of water quality parameters that are required for quality water. Water quality is determined by assessing its biological, chemical, and physical characteristics. In this study, a water quality assessment was carried out at the University of Eastern Philippines water system; which included a water refilling station, traditional water pumps, and the Alma Beach. The water samples, after the collection, were tested to identify the color, odor, pH, salinity, temperature, calcium content, magnesium content, sodium content, potassium content, and coliform count. After evaluation, all water samples conformed to the set standard by the PNSDW. However, the bacterial analysis showed that there is a sampling site that is not allowable for human consumption. In another area, the water quality assessment result for the Alma beach revealed that it is safe for recreational purposes and other recreational sports. But this does not mean that we should lay down our back, this calls for proper sanitary and environmental compliance regularly for the water systems in the university.

Assessing the Efficacy of Low-Dose Topical Atropine (0.01%) for Controlling the Progress of Myopia among School Children
Authors: Kher Praveena , Sharma Avi
Published: March 2022

Background: It is one of the most common abnormalities of human eyes and its incidence has dramatically risen in incidence in the last few decades. Myopia may lead to irreversible vision loss. A number of studies reflect on the effectiveness of low concentration atropine in controlling myopia. Atropine is used topically as a cycloplegic for the accommodation reflex and as a mydriatic for pupillary dilatation. Since myopia is leading cause of diminution of vision in early childhood, use of atropine (0.01%) in early stages can provide regression in myopic changes in eye. This study aimed to assess the change in spherical equivalent, changes in axial and keratometry values and retinal degenerative changes in cases of myopia treated with low dose atropine.

Methodology: The enrolled cases of myopia will undergo thorough ophthalmological examination and will be randomized into intervention and control groups. All cases in intervention group will be treated with low dose atropine (0.01%) eye drops at night and will be followed up every 6 months for examination. The control group will be provided refractive spectacles and also followed up every 6 months. The data from both groups will be compared and analysed.

Expected Results: Significant reduction in the progression of Myopia among school going children is expected with administration of 0.01% atropine eye drops.

Conclusion: Use of atropine (0.01%) in early stages can provide regression in myopic changes in eye.
