Published: March 2023

Este trabalho busca subsídios para a Organização do Conhecimento no domínio da Pesquisa Mineral. A linguagem natural possui fenômenos como sinonímia, homonímia ou, no contexto brasileiro, o regionalismo que geram ambiguidade semântica. As buscas em um Sistema de Recuperação da Informação requerem o uso da linguagem, essa prática linguística pode ser utilizada de muitas maneiras e em vários contextos, portanto, os Sistemas de Organização do Conhecimento – SOCs atuam como auxiliares nesse processo de busca em linguagem natural para a conversão da linguagem controlada. A base de qualquer representação de um domínio é um sistema de categorias. Que categorias podem ser identificadas na literatura científica e nos SOCs de Geociências para representar a área de Pesquisa Mineral? O objetivo deste artigo é identificar os padrões e estado da arte dos SOCs para a área de Geociências, e reunir as variações de representação da área de Pesquisa Mineral destes SOCs. A metodologia utilizada foi a pesquisa bibliográfica e análise de conteúdo dos documentos recuperados. Os resultados apontaram que grande parte da produção foi realizada em 2018, os países dos autores foram as duas maiores potências econômicas mundiais, EUA e China. Relacionado à análise dos modelos conceituais, acredita-se que eles não são suficientes para o objetivo proposto, como hipótese disso é levantado a questão da confidencialidade das informações geocientíficas. Acredita-se que ações para a padronização do conhecimento da Pesquisa Mineral auxiliará a melhorar a produtividade econômica da área, a fomentar a pesquisa e gerar novos conhecimentos.

Strategie uczenia się uczniów w edukacji wczesnoszkolnej w świetle badań
Authors: Rzońca Ewelina
Published: March 2023

Umiejętności uczenia się zostały zaliczone do kompetencji XXI wieku, co świadczy o ich  ważności w życiu jednostki. Są one  niezbędne w rozwoju osobistym i zawodowym człowieka w świecie dynamicznych zmian zachodzących w otaczającej nas rzeczywistości. Priorytetowe staje się wobec tego rozwijanie umiejętności uczenia się począwszy od edukacji wczesnoszkolnej. Główną rolę w tej kwestii odgrywa nauczyciel, który wspomaga w tym procesie. Współcześnie rysuje się obraz nauczyciela jako tutora towarzyszącego uczniowi na ścieżkach zdobywania wiedzy, z uwzględnieniem rozwoju umiejętności efektywnego uczenia się. Dlatego istotne jest, m.in.: pokazanie uczniom strategii uczenia się w celu efektywnego zapamiętywania treści, tworzenia notatek i usprawniania pamięci. W celu poznania strategii uczenia się uczniów oraz stosowanych technik przez nauczycieli przeprowadzono wywiady z uczniami klasy trzeciej szkoły podstawowej oraz nauczycielami edukacji wczesnoszkolnej. Uwagę skupiono wokół kilku zagadnień: jakie sposoby uczenia się wykorzystują uczniowie? czy korzystają z Internetu podczas uczenia się?; jakie strategie uczenia się wykorzystują nauczyciele w procesie dydaktycznym? Przeprowadzone badania posłużą sformułowaniu wniosków praktycznych przydatnych nauczycielom.
Specyfika i kierunki modernizacji w wychowaniu przedszkolnym w Łodzi w latach 1924-1939
Authors: Sosnowska Joanna
Published: March 2023

Celem badań w niniejszym szkicu była próba odtworzenia specyfiki i kierunków przeobrażeń, jakie w dziedzinie wychowania przedszkolnego w Łodzi nastąpiły w latach 1924-1939. Artykuł jest kontynuacją badań o tej problematyce (dla okresu 1918-1923); wyniki zaprezentowano wcześniej na łamach pisma Edukacja Elementarna w Teorii i Praktyce. Nowy problem badawczy stanowiła kwestia powołania z inicjatywy samorządu miasta Łodzi, pierwszej i kolejnych placówek przedszkolnych. Starano się prześledzić, w jaki sposób organizowano zaplecze materialne tych placówek, jak prowadzono pracę opiekuńczo-wychowawczą i dydaktyczną, czy uwzględniano nowe trendy pedagogiczne, z jakimi trudnościami się konfrontowano. W poszukiwaniu odpowiedzi sięgnięto do materiału źródłowego czasopiśmienniczego. Poddano kwerendzie dwa periodyki: pismo ogólnopolskie Przedszkole i o zasięgu lokalnym Dziennik Zarządu Miasta Łodzi. W wyniku badań stwierdzono, że nowy kierunek w wychowaniu przedszkolnym w Łodzi został wytyczony od połowy lat 20. XX w. dzięki powoływaniu publicznych placówek dla dzieci w wieku przedszkolnym oraz zatrudnieniu na stanowisku miejskiej inspektorki wychowania przedszkolnego Janiny Pawłowskiej. Wniosek z badań: znaczące zmiany, jakie w latach 1924-1939 dokonały się w łódzkich przedszkolach odnotowano w sferze wychowawczo-dydaktycznej, zwłaszcza w pracy z dzieckiem i jego rodziną. W myśl nowatorskich rozwiązań pedagogicznych starano się modernizować istniejące przedszkola i zakładać nowe, wyposażać w nowoczesne pomoce dydaktyczne, podnosić jakość pracy wychowawczej oraz wprowadzać do przedszkolnej przestrzeni nowe formy współpracy z rodzicami.

Authors: Skibska Joanna , Twaróg-Kanus Agnieszka
Published: March 2023

Podjęcie właściwych działań stymulujących rozwój ucznia i wspomagających opóźnione lub zaburzone sfery rozwojowe wymaga rozpoznania problemu poprzez przeprowadzenie diagnozy zmierzającej do poznania badanego dziecka i jego trudności. Celem badań było poznanie opinii nauczycieli szkół ogólnodostępnych i integracyjnych na temat procesu diagnozy pedagogicznej i jego składowych oraz ich wybranych uwarunkowań. W badaniu posłużono się metodą sondażu diagnostycznego, techniką ankiety. Kwestionariusz ankiety składał się z dwóch części. Część pierwsza kwestionariusza to dwa pytania otwarte dotyczące rozumienia przez badanych nauczycieli idei diagnozy i terapii. Natomiast część druga to pytania zamknięte (skategoryzowane), dotyczące aspektów procesu diagnozy i terapii pedagogicznej. Na potrzeby artykułu przeanalizowano tylko odpowiedzi z części drugiej kwestionariusza odnoszące się do procesu diagnozy i jego składowych. Zaprezentowane badania odnoszą się do ocen procesu diagnozy pedagogicznej z uwzględnieniem jego najważniejszych składowych wyłaniających się z przekonań badanych nauczycieli szkół ogólnodostępnych i integracyjnych pracujących z dziećmi ze specjalnymi potrzebami edukacyjnymi. Dodatkowo analiza wyników badań ukazuje postrzeganie procesu diagnozy pedagogicznej przez badanych nauczycieli przez pryzmat wybranych jej składowych, co pozwoliło na określenie struktury tego procesu krystalizującego się w opiniach nauczycieli szkół ogólnodostępnych i integracyjnych. Stwierdzono występowanie istotnych statystycznych różnic w odniesieniu do wskazań wiedzy i komunikacji jako istotnych składowych procesu diagnozy pedagogicznej przez nauczycieli szkół ogólnodostępnych posiadających dodatkowe kwalifikacje.
High efficiency perovskite/heterojunction crystalline silicon tandem solar cells: towards industrial-sized cell and module
Authors: Yamamoto Kenji , Mishima Ryota , Uzu Hisashi , Adachi Daisuke
Published: March 2023

29.2%-conversion efficiency of a two-terminal (2T) perovskite/crystalline Si heterojunction tandem solar cell using 145 μm thick industrial Czochralski (CZ) Si wafer is obtained. The structural optimization, such as surface passivation of the perovskite layer and better light management techniques, improved power conversion efficiency (PCE). To our knowledge, this PCE is the best in 2T-tandem solar cells using CZ wafers. Towards industrialization, crucial issues with the 2T tandem solar cells with crystalline Si bottom cell are discussed. Four-terminal (4T) tandem solar cells are evaluated as an approach to avoid the crucial issues. Examining our base technologies which realize 22.2%-conversion efficiency perovskite single junction solar cell module and 26%-heterojunction back-contact solar cells, we clarified that the based technologies were ready to realize 30%-conversion efficiency 4T perovskite/heterojunction crystalline Si tandem solar cells with approximately quarter size of an industrial crystalline Si solar cell (∼64 cm2).

Authors: Ito Yoshiyasu , Goto Takumi , Suenaga Rieko , Omote Kazuhiko
Published: March 2023

In order to realize non-destructive cross-sectional profile measurement for deep hole advanced devices, we have applied a transmission small angle X-ray scattering instrument that employs a Mo-target X-ray source and a high-sensitivity two-dimensional detector. It enables us to measure the average cross-sectional profile of periodic hole patterns that are several tens of nanometers in diameter and several micrometers in depth. The structure, characterized by hole diameter, tilt angle, and ellipticity as functions of depth, was successfully evaluated. The obtained average depth profile of the holes was compared with that from a cross-sectional SEM and a milling SEM, and it was confirmed that they agreed very well.

Published: March 2023

A pesar de que la igualdad entre mujeres y hombres es un principio básico de nuestra sociedad, la realidad nos muestra lo lejos que estamos de ella. La feminización de la pobreza, la violencia sexual y los asesinatos de mujeres son la parte más visible de unas desigualdades estructurales que cuentan, entre sus principales mecanismos de reproducción, con la socialización diferencial de niñas y niños, de adolescentes y de jóvenes, de acuerdo con unos modelos de género que son obsoletos y tóxicos. El amplio volumen de estudios y propuestas para introducir la perspectiva de la igualdad de género en la escuela contrasta con la escasez de textos centrados en el ámbito de la educación social. La educación para la igualdad de género. Una propuesta formativa para educadoras y educadores sociales viene a cubrir este vacío en la literatura sobre el tema. En este libro, orientado a la formación de estudiantes y profesionales del ámbito de la educación social, se desarrollan los aspectos teoricoconceptuales de la educación para la igualdad de género y se analizan las políticas de igualdad y la educación para la igualdad en España desde la Constitución hasta la actualidad. A partir de estos planteamientos se realiza una propuesta formativa que, además, viene avalada por la experiencia como profesoras e investigadoras de las autoras.

Published: March 2023

Background: Microbial exposures have been suggested to confer protection from allergic disorders, and reduced exposures to gastrointestinal microbes have been proposed as an explanation for the increase in asthma severity and prevalence. Since the general prevalence of Helicobacter pylori has been decreasing, we hypothesized that H. pylori serostatus may be inversely related to the severity of asthma.
Objective: The aim of this study is to find whether infection with H. pylori reduces the probability of development of severe asthma in patients with persistent asthma.
Methodology: In this study fifty patients with persistent asthma includes 19 males and 31 females their ages range between (17 – 66) years For all those patients, full history and complete physical examination have been done, then after, the patients subjected to pulmonary function test. After that, two milliliters sample of venous blood have been drawn, then, the sample centrifuged and sent to assess for H. pylori infection serology. Data was analyzed by using SPSS.
Results: There is significant association between severity of asthma and result of H. pylori so with increase severity of asthma there is decrease in percentage of positive H. pylori serology. And there is no statistical significant are noted between patients sex or age and results of H. pylori infection test.
Conclusion: There is significant inverse association between severity of asthma and result of H. pylori infection serology. This association not affected by ages and sex of patients.
Recommendations: Since the exact mechanism by which H. pylori affect asthma is not clear, there is need for further studies to explore it.

Beneficial Synergistic Effect of Supplementation with Combined M. oleifera and L. speciosa Leaf Capsules in Patients with Type 2 Diabetes
Authors: Hassan Nazia
Published: March 2023

Diabetes mellitus is a metabolic non-communicable chronic disease in which the body's ability to process glucose is impaired, resulting in higher blood glucose levels.  If not controlled, this disease can lead to severe complications.  Various plants with medicinal properties can treat chronic diseases, such as diabetes, due to therapeutically important phytochemicals and bioactive compounds.  This study investigated the effect of antidiabetic medicinal plant leaves in controlling blood glucose levels among Wakhi diabetic patients in the Hunza district of Pakistan.  The "Wakhis" are an ethnic group living in the remote region of Pakistan.  The method used in this study was a placebo-controlled study.  Leaf powders of Moringa oleifera and Lagerstroemia speciosa were filled in capsules of 1000 mg each.  The antidiabetic potential of the medicinal plants was estimated by performing the biochemical blood profiles of diabetic patients before and after the trial.  After the intervention, the level of glycated hemoglobin (HbA1c) reduced from 8.3±1.8 to 7.5±1.2% significantly (P = 0.0401).  The fasting blood sugar (FBS) in the intervention group reduced significantly from 191±49 mg/dL to 169±41 mg/dL (P = 0.0041) after the trial.  According to the findings of this study, the combined herbal capsules effectively controlled the blood sugar of type 2 diabetic patients.  Conclusively, the combination of M. oleifera and L. speciosa have the potential to lower blood sugar levels supplementary to existing regimens.  Further investigation is warranted to explore the mechanism resulting in the observed reduction in sugar levels in type 2 diabetic patients.

Published: March 2023

Polycystic ovarian syndrome (PCOS) is a complex condition. In PCOS the metabolic and endocrine components are affected. The PCOS is an evolving condition and therefore has variable ultrasound presentations. Inappropriate gonadotrophin secretion causes ovarian dysfunction. Increased level of plasma testosterone is a common feature in PCOS. Women with PCOS have abnormalities in the metabolism of androgens and oestrogen. PCOS is a genetically heterogeneous syndrome. The abnormal menstruation patterns in PCOS is attributed to chronic anovulation. Women with PCOS should be assessed for their cardiovascular risk. The lifestyle modifications such as reducing the weight, increasing the exercise and restriction of carbohydrate intake consistently reduce the risk of diabetes. Medical management of PCOS is aimed at the treatment of metabolic derangements, anovulation, hirsutism and menstrual irregularity. The surgical management of PCOS is aimed mainly to improve ovulation. PCOS has many long-term complications. Therefore the patients need regular follow-up with their physicians for early detection and management of any untoward sequelae associated with the syndrome.

Published: March 2023

This study looked into pension assets investments and its impact in the Nigerian economy. The investments includes quarterly reports of corporate debt securities, government bond securities, mutual funds’ investments, money market instruments, private equity funds and real estate securities from 2004 – 2020, and was sourced from the statistics database of the National Pension Commission, the Central Bank of Nigeria and the World data bank. The statistical measures used to analyze the data are the descriptive test, Unit root test, Co-integration test, Vector error correction, Causality and Impulse response function. The outcome of the analysis show that the variables were stationary after first differences were taken; and were also co-integrated at 2 lags indicating that both short and long run equilibrium relationship exist among the variables. From the vector error correction model, previous years’ deviations from long run equilibrium had a 0.09% speed of adjustment; leading to a short run equilibrium. The Causality test reveal that changes in government bond securities lead to changes in real estate securities and changes in money market investments leads to changes in government bond securities. In addition, the impulse response demonstrates that a shock to the system produces more negative responses than positive ones. The study thus recommends that the pension industry should vigorously create more awareness on the importance of employee pension plan; develop more e-channels to help rake in investible funds as well as develop more innovative products to support diversification of pension fund in different assets classes among others.
Nexus between Exchange Rate Volatility and Oil Price Fluctuations: Evidence from India
Authors: Ali Nazar , Mittal Ashok
Published: March 2023

The price of crude oil has fluctuated in India over the past few decades which has drawn significant attention because of it impact on all economic sectors. The present study aims to identify how oil price volatility affects the real exchange rate in India from 1st July 2009 to 2nd January 2020. For short-run and long-run analysis, various econometric methods have been applied, including Granger Causality, ARDL Bound test, FEVD, and IRF. The study divided the entire sample into sub-samples based on Breakpoint analysis and then performed the ARDL Bound testing procedure in each sub-sample. Causality results revealed that most samples exhibited strong unidirectional causality from oil prices to exchange rates. However, the long-run and short-run results from the ARDL model failed to detect any cointegration among the underlying variables for the entire sample. The calculated F-statistics is 4.35, which is less than the lower and upper critical bound values provided by Pesaran, Shin, and Smith (2001). The GIRF has been used to calculate the dynamic marginal effect of a one-standard-deviation shock in oil prices on the current and future values of the Rupee-Dollar exchange rate. The exchange rate fell in the first three samples due to one standard deviation shock in oil prices. However, the contribution of oil prices to the exchange rate is positive in the fourth sample period.
