Kegiatan belajar merupakan kegiatan yang berpotensi berkembang menjadi tindakan belajar. Pembelajaran tersebut dapat diukur dari hasil belajar siswa. Hasil belajar siswa dapat menunjukkan tercapai atau tidaknya tujuan pembelajaran dengan menunjukkan bahwa tujuan pengajaran tersebut merupakan hasil belajar bagi siswa yang telah menyelesaikan proses pembelajaran di bawah bimbingan guru dalam kondisi yang baik. Ilmu alam (IPA) adalah studi tentang alam semesta melalui penelitian metodis. Ilmu Pengetahuan Alam (IPA) adalah mata pelajaran yang diajarkan di sekolah dasar yang bertujuan untuk memberikan siswa pengetahuan, konsep, dan gagasan yang terorganisir tentang dunia alam. Karena pendidikan IPA selama ini disamakan dengan pembelajaran yang didominasi oleh latihan-latihan menghafal, pengajar terkadang masih terbentur pada masalah siswa yang tidak berminat mempelajarinya. Pembelajaran Ilmu Pengetahuan Alam (IPA) membutuhkan perpaduan antara teori dan praktik untuk meningkatkan kemampuan proses siswa, namun masih banyak kasus dimana guru hanya memberikan penjelasan dari buku tanpa memberikan nilai pada praktik. Untuk meningkatkan hasil belajar IPA, penulis bertujuan untuk menggunakan PBL atau pembelajaran berbasis masalah pada siswa kelas IV SD Negeri Plaosan 1. Peneliti berusaha memasukkan pendekatan pembelajaran berbasis PBL ke dalam pengajaran sains. Strategi ini akan menghasilkan pembelajaran yang fleksibel, penuh kolaborasi siswa, dan mempersiapkan siswa untuk memahami informasi yang diberikan oleh pengajar.

Analysis of dynamical systems with discrete noise injection events
Authors: Vahdat Zahra , Singh Abhyudai
Published: April 2023

The canonical approach to modeling stochasticity considers a dynamical system driven by Gaussian white noise. Here, we propose an alternative hybrid formulation, in which continuous dynamics is interspersed with noise injection events that occur at discrete times. The time interval between two successive events is drawn from an arbitrary, positively-valued continuous distribution. Although the hybrid approach converges to the classical stochastic differential equation when events occur sufficiently fast, the hybrid formulation captures a wider range of stochastic phenomena that deviate from Gaussian statistics when events occur at slower timescales. These deviations are mathematically captured by exact analytical expressions for higher-order moments, such as skewness and kurtosis of the state space. We illustrate this approach with the example of a nanosensor impacted by collisions from surrounding molecules. Our results provide an important generalization to capture the stochastic dynamics of physical, biological, and engineering systems and reveal a novel approach for exploiting high-order moments to infer parameters that are not observable in lower-order moments.

THE MULTIFACTORIALITY OF THE PROCEDURE FOR OPTIMIZING THE DESIGN OF A TWISTED HEAT EXCHANGER LOCATED IN AN ANNULAR CHANNEL DURING LAMINAR MOTION
Authors: Tuz V.O. , Lebed N.L. , Lytvynenko M.P.
Published: April 2023

Cryogenic units that operate on the J-T (Joule-Thomson) cycle have found wide application due to the relatively simple design of the main elements, low operating costs, reliability and long service life. To a large extent, the efficiency of the installation depends on the choice of the coolant, the schematic solution, as well as on the design of the recuperative heat exchanger. The ability to compensate for temperature and mechanical stresses due to the twisted structure ensures long-term and trouble-free operation of the heat exchange equipment. The main goal of many studies was to determine the influence of thermophysical properties of the coolant, its mode parameters and geometric characteristics of the surface on heat exchange and hydrodynamics. On the basis of the results of the research, the optimization of the structure was carried out and empirical dependencies were given for calculating its parameters. The analysis of the presented empirical dependencies does not give a final answer regarding the development of a generalized method of calculating microheat exchangers of the Hampson type used in cryogenic installations. It is proposed to calculate the geometric characteristics of this type of heat exchangers, taking into account the influence on the intensity of heat exchange not only of the mode parameters of the heat carrier and the working fluid, but also of the design characteristics of the equipment, namely: the diameter and length of the pipe, the diameter of the coil, the gap between the heat exchange surface and the outer and inner casings, step characteristics of the coil. The work implements the methodology of calculation and optimization of the design of a twisted heat exchanger located in an annular channel with forced convection and laminar flow regime. The main emphasis is made on taking into account the change in the intensity of heat exchange along the length of the heat exchange surface, the length of the initial heat section is determined. An experimental study of heat exchange processes during forced convection of gas in a coiled heat exchanger in the laminar mode of movement of the heat carrier made it possible to establish the dependence of the heat transfer coefficient aк on the main geometric characteristics of the heat exchanger: the relative pitch of the coil, the gap between the heat exchange pipe and the outer and inner surfaces of the housing. On the basis of research results, dimensionless corrections were determined, with the help of which variational calculations of twisted heat exchanger structures located in annular channels are performed in order to optimize their geometric characteristics.

Authors:   SRMIST, Manikandan T.T. , Sukumaran Rajeev ,   SRMIST
Published: April 2023

Aquaculture is gradually moving toward Open Ocean Fish Farming (OOFF) in recent times because of the huge environmental impacts caused by onshore fish farming. Although Offshore fish farming has a lot of benefits over onshore fish farming it has its threats as well. Harmful Algae Blooms (HAB) are one such threat to Offshore fish farming. HAB is the formation of algae in groups that are toxic. The HAB can significantly affect the health of the fish that are being cultured. To prevent and act on HAB, monitoring of different environmental parameters is done in the field that is of concern. Traditionally for these kinds of monitoring human drivers are employed. But involving human drivers for monitoring in offshore conditions is cost expensive and difficult. Technology-enabled autonomous monitoring is needed in an offshore environment. Here comes underwater Wireless Sensor Networks (UWSN) which can be used for inspection of underwater fish farms for the detection of HAB. In UWSN loss is one of the main parameters that affect the Quality of Service. So this research focuses on the development of a Stochastic Network Calculus (SNC) based mathematical model of the network layer design for underwater communication that can be used in OOFF. In this work, we introduced the loss factor parameter into SNC and derived the loss bound for underwater communication, and the same is evaluated using discrete event simulation.

Research, testing and experimental substantiation of the possibility of using remote sensing data obtained from a spectrometer installed on an unmanned aerial vehicle (UAV) and satellite data to assess the presence of hydrocarbon deposits within geological structures has been carried out. The test area was chosen as the Vostochnorogintsevska area (Velikobubnivsky Val of the Dnipro-Donetsk Basin) with available hydrocarbon deposits (HC), productive and unproductive wells, the research route was laid between unproductive and productive wells. The main advantage of this territory is the availability of the results of processing primary data of ground measurements and remote sensing obtained by various types of equipment from 1999 to 2021. The study is devoted to the comparative analysis of vegetation indices, which are calculated from remote data obtained by a multispectral camera mounted on an UAV and Sentinel-2 satellite data. It was determined that these data have a high degree of correlation, reflect changes in the state of vegetation, caused by the presence of HC deposits, tectonically active fault zones, and have significant indicative value. The obtained results provide a basis for the effective use of UAVs in the structure of the methodology for solving oil and gas exploration tasks on land.

O objetivo desta pesquisa foi identificar na literatura científica as atuações da equipe multiprofissional na prevenção da violência obstétrica. Para tal, realizou-se uma revisão narrativa da literatura. Os estudos foram selecionados a partir de busca online das seguintes bases de dados: SCIELO, BVS e PubMed. Foram utilizados os seguintes descritores controlados: “Saúde da Mulher”, “Violência Obstétrica”, Parto e “Equipe Multiprofissional”, “Assistência em Saúde”. Foram coletados 516 estudos, contudo se enquadraram como amostra desta pesquisa 07 artigos. A literatura corrobora que a forma mais eficaz de combater a violência obstétrica é por meio da qualificação profissional, com capacitações constantes sobre temas que englobam os direitos humanos e a humanização da assistência em saúde. Constatou-se que a violência obstétrica é mais evidente em mulheres vulneráveis. Este tipo de violência ainda é muito presente nas unidades de saúde e corriqueiramente pela falta de debate e visibilidade da temática em questão, boa parte das mulheres sofrem essa violência sem compreenderem que estão sendo vítimas num momento tão delicado de suas vidas. O enfrentamento da violência obstétrica deve acontecer a partir da educação continuada da equipe pensando na desconstrução desta cultura impregnada na sociedade.

Resgatando a Política Nacional de Ordenamento Territorial. Iniciativas no período de 2015 a 2021.
Authors: Alves Cintia de Souza
Published: April 2023

Este artigo atualiza o registro da Política Nacional de Ordenamento Territorial – PNOT brasileira. Relata as iniciativas para retomá-la entre os anos de 2015 e 2021; as metamorfoses, os avanços e cerceamentos que sofreu. A primeira tentativa de PNOT em sentido lato, iniciada em 2003, foi abandonada em 2009 e permanece esquecida. Todavia, houve recentemente, ao longo de 2020 e 2021, tentativas de dar-lhe alguma continuidade. No entanto, condições adversas impuseram sua redução a apenas um projeto e a uma área-piloto. Os dados apresentados advêm de pesquisa documental e, sobretudo, de relatos obtidos em entrevistas, tanto com participantes do período aqui focado quanto com envolvidos na tentativa predecessora. Considerando-se que a visão de país, a escala nacional e os eixos temáticos de um ordenamento territorial abrangente, assim como a falta de articulação das políticas federais e a forma de geri-las se perderam desde seu abandono há mais de uma década, o relato das experiências recentes de formulação de uma PNOT é aqui colocado como uma fonte de reflexão e discussão; talvez de preparo para uma transformação no planejamento e na gestão do ordenamento territorial no Brasil em uma fase vindoura, pós 2022.
As desigualdades de acessibilidade às oportunidades cotidianas na Região Metropolitana de Belo Horizonte
Authors: Cerqueira Eugênia Viana , Diniz Alexandre Magno Alves
Published: April 2023

A presente investigação pretende traçar uma exploração das desigualdades de acessibilidade às oportunidades cotidianas na Região Metropolitana de Belo Horizonte (RMBH), questionando se as recentes inflexões observadas nas periferias metropolitanas poderiam mitigar o padrão desigual centro-periferia dominante nas grandes cidades brasileiras. A metodologia de pesquisa articula um indicador cumulativo de acessibilidade à análise da distribuição espacial das oportunidades e das diversas categorias da população. Os resultados apontam, dois processos opostos de segregação. Por um lado, a permanência de expressivas desigualdades, demonstrando que os indivíduos de baixa renda das periferias metropolitanas apresentam baixos níveis de acessibilidade. Por outro lado, destaca-se, que o desenvolvimento de novas estruturas periféricas atrelados ao deslocamento de camadas de alta renda para as periferias, em um movimento de autossegregação, configura zonas de alta acessibilidade nas periferias urbanas. Além disso, os resultados apontam que, dentre os diferentes tipos de oportunidades estudadas, os equipamentos de saúde aqueles apresentam um padrão mais desigual de acesso potencial, devido à intensa concentração no centro Belo Horizonte.

Processus de scale-up et fonctionnement du CA naissant : Le rôle de l’attention et de l’auto-efficacité
Authors: Bédat Joëlle , Wirtz Peter
Published: April 2023

Cet article rapporte une étude pluriannuelle et processuelle d’une jeune scale-up et de son conseil d’administration (CA), en se focalisant sur l’attention et l’auto-efficacité de ses protagonistes pour mieux comprendre le mode de fonctionnement du CA. Les résultats permettent de mieux comprendre ce qui fait que, concrètement et au-delà du cycle de vie, le conseil d’administration s’engage dans un mode de fonctionnement disciplinaire et/ou cognitif. Nous montrons que l’intensité du traitement respectif des enjeux cognitifs et disciplinaires change d’une phase à l’autre du processus de scale-up, notamment, mais pas seulement, lors de l’entrée de nouveaux investisseurs. L’attention portée aux différents enjeux cognitifs et disciplinaires comporte des dimensions situées, organisationnelles et individuelles. Le principal résultat consiste à montrer, à l’instar de Knockaert et al. (2015), que les variables d’attention et d’auto-efficacité influencent fortement le fonctionnement disciplinaire et cognitif du CA, mais contrairement aux résultats des auteurs précités, il apparaît que l’attention et l’auto-efficacité participent à un processus complexe et dynamique. Ils changent d’objet en fonction du temps et des administrateurs et entraînent ainsi des changements dynamiques du fonctionnement du conseil.

Good quality health, nutrition and demographic survey data are vital for evidence-based decision-making. Existing literature indicates system specific, data collection and reporting gaps that affect quality of health, nutrition and demographic survey data, thereby affecting its usability and relevance. To mitigate these, the National Data Quality Forum (NDQF), under the Indian Council of Medical Research (ICMR) - National Institute of Medical Statistics (NIMS) developed the National Guidelines for Data Quality in Surveys delineating assurance mechanisms to generate standard quality data in surveys. The present article highlights the principles from the guidelines for informing survey researchers/organizations in generating good quality survey data. It describes the process of development of the national guidelines, principles for each of the survey phases listed in the document and applicability of them to data user for ensuring data quality. The guidelines may be useful to a broad-spectrum of audience such as data producers from government and non-government organizations, policy makers, research institutions, as well as individual researchers, thereby playing a vital role in improving quality of health, nutrition and demographic data ecosystem.
Molecular characterization & recombination analysis of complete enterovirus-88 isolated from acute flaccid paralysis cases in India

Published: April 2023

Background & objectives:

Focus on non-polio enteroviruses (NPEVs) causing acute flaccid paralysis (AFP) due to myelitis has increased with the containment of the poliovirus. Enterovirus-B88 (EV-B88) has been associated with the AFP cases in Bangladesh, Ghana, South Africa, Thailand and India. In India, EV-B88 infection was linked to AFP a decade ago; however, to date, no complete genome has been made available. In this study, the complete genome sequence of EV-B88 was identified and reported from two different States (Bihar and Uttar Pradesh) in India using the next-generation sequencing technique.

Methods:

Virus isolation was performed on the three AFP suspected cases as per the WHO-recommended protocol. Samples showing cytopathic effects in the human Rhabdocarcinoma were labelled as NPEVs. Next-generation sequencing was performed on these NPEVs to identify the aetiological agent. The contiguous sequences (contigs) generated were identified, and reference-based mapping was performed.

Results:

EV-B88 sequences retrieved in our study were found to be 83 per cent similar to the EV-B88 isolate from Bangladesh in 2001 (strain: BAN01-10398; Accession number: AY843306.1). Recombination analyses of these samples demonstrate recombination events with sequences from echovirus-18 and echovirus-30.

Interpretation & conclusions:

Recombination events in the EV-B serotypes are known, and this work reconfirms the same for EV-B88 isolates also. This study is a step in increasing the awareness about EV-B88 in India and emphasizes future studies to be conducted in the identification of other types of EV present in India.

Published: April 2023

Background & objectives:

Studies have shown that insulin resistance and hyperinsulinaemia play a major role in the pathogenesis of polycystic ovary syndrome (PCOS). Therefore, the use of insulin sensitizing drugs in the treatment of PCOS has attracted the attention of medicine and researchers. The aim of this study was to investigate the effects of sitaformin (sitagliptin/metformin) and metformin on the quality of oocyte and embryo in classic PCOS patients undergoing intracytoplasmic sperm injection (ICSI).

Methods:

Sixty patients of PCOS (25-35 yr) were randomly allocated into three groups (n=20, each group): a metformin-treated group (administered metformin 500 mg twice daily), a sitaformin-treated group (administered sitaformin 50/500 mg twice daily) and a placebo group. Participants in all the groups received the drug two months prior to the start of the ovulation cycle and treatment continued until the day of the oocyte aspiration.

Results:

Serum insulin and total testosterone levels decreaseed significantly after treatment in both the treatment groups as compared to the placebo (P<0.05). A significant decrease in the number of immature oocytes [MI + germinal vesicle (GV) stage] was observed in metformin and sitaformin groups as compared to the placebo. In addition, sitaformin group when compared to the metformin group showed a significant decrease in the number of immature oocytes (P<0.05). The number of mature and normal MII oocytes increased significantly in both the treatment groups compared to the placebo group (P<0.05). The number of mature and normal oocytes increased in sitaformin group in comparison to the metformin group, but the difference was not significant. There was a significant increase in the number of grade I embryos, fertilization and cleavage rates in the sitaformin group compared to the other groups (P<0.05).

Interpretation & conclusions:

This is the first study to compare the impact of sitaformin with metformin on oocyte and embryo quality in women with PCOS undergoing a gonadotropin-releasing hormone (GnRH) antagonist cycle. In conclusion, sitaformin can be more effective in decreasing immature oocytes and increasing the quality of embryos than the use of metformin.
