The article presents the results of research aimed at revealing the influence of the main alloying elements on the formation of the initial grain structure, on phase transformations and on structural changes that occur during superplastic deformation of several aluminum alloys. It was possible to form a homogeneous ultrafine-grained structure in samples of alloys Al - 4.1 wt.% Mg - 0.5 wt.% Zr and 1423 due to dynamic recrystallization during their superplastic deformation. It is revealed that the initial microstructure of the 1420T alloy samples is bimodal. The average grain size is approximately 5 μm, in some areas of the working part of the samples there are large elongated grains, the average size of which is approximately equal to 25 μm. The initial structure of alloy 1421 samples is fine-grained, and the initial structure of alloy 1423 samples is multi-grained and coarse-grained. Metallographic studies showed that the grain structure of samples of alloys 1420T, 1421 and 1423 increases slightly during superplastic deformation at high homologous temperatures. Cavitation accumulates in the samples and structural changes occur, which are probably associated with local melting at grain boundaries and at interphase boundaries. It was established that the presence of zirconium and scandium additions in the composition of the samples ensures the formation of an ultrafine-grained structure in them and counteracts the grain growth during superplastic flow. Magnesium and lithium, which are included in the samples of the studied alloys 1420T, 1421 and 1423, form several intermetallic phases with aluminum. These phases are part of mixtures of crystals of peritectic origin, which are localized in the form of layers between some grains. The occurrence of peritectic reactions at high homologous temperatures can be one of the reasons for the partial melting of samples of alloys 1420T, 1421, and 1423 during their superplastic deformation. Partial melting of samples of alloys 1420T, 1421 and 1423 can probably be carried out due to the presence of segregations of magnesium and lithium at the grain boundaries, which lower the melting temperature of the aluminum-based solid solution. Partial melting of samples of alloys 1420T, 1421, and 1423 during their superplastic deformation, which is performed at high homologous temperatures, leads to the formation of cells of a metastable liquid-solid phase at the grain boundaries, the viscous flow of which leads to the formation of fibrous structures due to the development of grain boundary sliding.

The influence of medium doses (from 1019 cm–2 to 1020 cm–2) of irradiation with fast electrons and changes in the concentration of praseodymium in the interval 0.0 ≤ z ≤ 0.5 on the excess conductivity of optimally oxygen-doped Y1Ba2Cu3O7-δ single crystals was studied. It is shown that electron irradiation and an increase in the degree of doping with praseodymium leads to a significant expansion of the temperature interval of the existence of excess conductivity, thereby narrowing the region of the linear dependence of r(Т) in the ab-plane. It was established that at doses 0 ≤ D ≤ 6.5´1019 cm–2 the value of the value of the transverse coherence length ξс(0) increases with an increase in D approximately 3 times and more than four times as the praseodymium content in the sample increases to z ≈ 0.42. At the same time, in both cases, the 2D-3D crossover point is shifted by temperature. In contrast to the case of irradiation with small doses (D ≤ 1019 cm–2) and doping with praseodymium up to concentrations z ≤ 0.39, irradiation with medium doses and doping with praseodymium at higher concentrations leads to a non-monotonic dependence of the transverse coherence length xс(0) with characteristic maxima at D ~ (7-8)´1019 cm–2 and z ≈ 0.42, which may be related to the general suppression of superconducting characteristics.

An effective way to create self-organizing arrays of metal particles is to melt thin layers of substance on a poorly wetted surface. Such arrays may improve the technological properties of functional structures, and are themselves functional elements of modern devices and systems.

During the melting of a solid layer on a poorly wetted substrate, an array of spherical particles is formed, which are evenly distributed over the surface of the substrate. The distribution of particles by size is determined by the thickness of the fusible layer and conditions of the deposition. The location of islands, formed after the melting of vapour-crystal deposited solid films, is determined primarily by the initial stages of de-wetting, when the thin continuous film starts to decay while remaining in solid state.

This work studied self-organizing processes during the melting of Pb films deposited on a Ta substrate. The films were deposited on glass plates in a high vacuum and then after deposition were heated to a temperature slightly above the Pb melting point. After the heat treatment the samples were removed from the vacuum chamber and examined using SEM microscopy and EDS analysis.

It was discovered that arrays of spherical particles are formed during the melting of micron-thick Pb films. The histograms of the size distribution of such particles are quite wide and can be represented as bimodal with partially overlapping maxima. This can be explained by active coalescence processes in thicker samples. This study demonstrated that small temperature gradients can cause noticeable kinetic effects that allow separate particles to move macroscopic distances and capture the surrounding substance. The study also estimated the energy associated with the optimization of the morphological structure of vacuum condensate and which is a physical factor of de-wetting.

Published: December 2023

This study was conducted to evaluate the cadmium contamination level in milk products
containing cocoa (chocolate flavour milk products), and its dietary exposure in vulnerable
consumers, i.e. children aged one to five years old, pregnant and lactating women (PLW)
in Indonesia. A total of 78 samples of milk products, which were registered in the
Indonesian National Agency of Drug and Food Control (NADFC) and distributed in the
Indonesian market, were analysed using Atomic Absorption Spectrophotometry Graphite
Furnace (AAS-GF). Milk powder for children aged one to five years, UHT liquid milk,
and condensed milk meet the NADFC regulation No. 5 of 2018. However, 63% of
chocolate flavour PLW milk powder had Cd levels that exceeded the NADFC (maximum
10 µg/kg). Chocolate flavour milk has a higher Cd level than non-chocolate flavour milk
products. The highest value of Cd exposure was in children aged three to five years old
who consumed chocolate flavour milk powder, with an average value of 0.095 and P95
value of 0.151 µg/kg BW/day. However, based on the P95 exposure value, the
contribution of Cd exposure for this product was only 18.12 and 42.27% to the PTMIJECFA and TWI-EFSA values, therefore, it was not considered a risk of health problems.
For PLW milk powder, although 63% of samples exceeded the NADFC regulation, the
P95 value of Cd exposure was 1.41 and 3.29% to the PTMI and TWI value, therefore, it
was also considered not to pose a risk of health problems.

Published: December 2023

Este estudo foi realizado a partir de uma reflexão crítica e social acerca dos fenômenos que permeiam a transferência de fundos públicos para a educação superior privado-mercantil. Como caminho de pesquisa, adota os pressupostos da técnica de análise de conjuntura segundo Souza (1985), priorizando acontecimentos, atores e cenários que determinam a agenda privado-mercantil na Educação Superior. De forma mais específica, discute o contexto de apreensão das dinâmicas ultraneoliberais que alicerçaram os governos Temer e Bolsonaro (2016-2021), e questiona como elas aportam o fomento necessário para a concretização da agenda de mercantilização e financeirização da educação superior. O estudo conclui que a gestão bolsonarista solapou os recursos para manutenção das universidades públicas, gerando um processo crescente de desregulação quanto ao reconhecimento e manutenção dos cursos de graduação e pós-graduação; a desautonomização destas instituições; e pelo astuto dimensionamento de recursos do fundo público para conglomerados e entidades educacionais privadas, atendendo a interesses mercadológicos e privatistas.

A presente pesquisa, de cunho qualitativo, tem como objetivo investigar os reflexos da aplicação do Sistema de Avaliação de Rendimento Escolar do Rio Grande do Sul (SAERS) em seis escolas públicas do município de Rio Grande, no estado do Rio Grande do Sul. Para tanto, contou com suporte metodológico da Análise Temática Reflexiva (ATR) orientada pelos estudos de Marques e Graeff (2022) e Souza (2019). Os dados foram produzidos entre os meses de dezembro de 2022 a março de 2023, através de questionários compostos por seis perguntas, que foram respondidas por escrito por 12 professoras de 2º e 5º ano do Ensino Fundamental. Realizou-se, também, uma análise documental do Decreto nº 56.679 que instituiu o SAERS. O referencial teórico baseou-se, principalmente, em Afonso (2013), Harvey (2014) e Laval (2004) que auxiliaram na análise do contexto neoliberal das atuais políticas públicas de avaliação. Como resultado mais evidente foi possível perceber impactos da prova para discentes e docentes, seja porque interferiram na prática docente ou porque abalaram psicologicamente os discentes envolvidos.

The COVID-19 pandemic in 2020 has triggered governments worldwide, including WHO Indonesia, to use social media as an essential tool for digital education dissemination. In this case, WHO Indonesia uses Instagram to share posters, with a visual emphasis through the use of color in the word 'COVID-19'. This study aims to describe how colors are represented in the word COVID-19 on WHO Indonesia's Instagram posters. This study uses qualitative research. This study was analyzed using content analysis. The results reveal that the word COVID-19 in each poster content uploaded by WHO Indonesia has a variety of colors. The color representations contained in the word COVID-19 are red as a risk warning to smokers, dark orange as sensitivity and empathy for survivors of violence, yellow-gold as a reminder of healthy activities at home, indigo as awareness of body health, teal green as maintaining physical distance, dodger blue as maintaining health during a pandemic, sienna as resilience and fortitude in facing the pandemic, white as preventing the spread of the virus, and dim gray as serious form in facing COVID-19. This study aids in comprehending the reasoning behind the selection of specific colors in the posters utilized by WHO Indonesia in their digital education endeavors regarding COVID-19. It can prove beneficial in designing more impactful health messages and understanding the influence of colors on individuals' perceptions and reactions.
Nosaviraka’s Ritual Mantra on The Quran And Hadits: Intertextual Analysis
Authors: Nuraeni Ida , Yunidar Yunidar , Akbar Akbar
Published: December 2023

This intertextual analysis of the mantras in the Nosaviraka healing ritual does not intend to compare the contents of the Quran and Hadits with the oral text of the mantras because the Quran is a sacred divine word without the intervention of creatures. The study aims to describe the relationship between Nosaviraka healing ritual, the Kaili tribe in Central Sulawesi and the the Quran and Hadits. The method used in this research is descriptive qualitative with an intertextual approach.  The data source for this research is Nosaviraka healing ritual. The data in the form of the arrays in the mantras were analyzed using the intertextual theory, namely determining the link between the arrays of the mantras and the Quran and Hadits. Based on the research results obtained three findings. First, here is a relationship between the text of the Nosaviraka mantra and the text of the Quran and Hadits. This relationship is shown in all parts of the mantra, namely (a) the initial mantra of agreement, (b) the mantra of summoning ancestors, (c) the mantra of healing, (d) the mantra of salvation, and (e) the mantra of the end. Second, the Nosaviraka ritual mantra as a hypogram, while the text of the Quran and Hadits as the owner of the transformation. Directly or indirectly, the Nosaviraka mantra, the Quran, and the Hadits can be seen from the similarity in structure, but the use of imagination is slightly different in theme. Third, there is a strong tendency that the Nosaviraka mantra is a form of belief in Allah SWT which is associated with the Quran as its hypogram.
Layered Sexism in The Accused
Authors: Siahaan Annette Prizyllia , Budhyono Rasus , Manggong Lestari
Published: December 2023

The Accused (1988), a movie adaptation of a real-life event about a gang-raped victim who seeks justice, depicts sexist behavior towards the survivor during the trial. With the main premise of seeking justice for a rape survivor, this movie highlights Sarah’s experience to gain justice through a sexist masculine institution. Referring to the theory of sexism by Manne, this article aims to show how this movie shows sexist behavior toward the survivor during law enforcement. Dialogues that show sexism between characters are used in the analysis of the movie's plot, then used to discuss the portrayal of sexism in The Accused from a feminist point of view. From the dialog and the portrayal of layered sexism, we find that as a movie promoting human rights, The Accused still implies that a woman who does not meet the expected gender roles is undeserving of justice. As a result, a ‘bad’ woman as a victim whose experience is reduced is seen as a norm.

Authors: Ilin V. D. , Mashtakov A. P.
Published: December 2023

The objects of research are supersonic composite jet flows, as well as structural elements of flows (shock and acoustic waves, gas dynamic discontinuity surfaces), which act with each other and with various technical objects. Such objects may be structural elements or parts of special technical systems that experience loads during operation, or are subjected to targeted effects in order to improve their mechanical properties. The research is carried out in order to develop mathematical models describing the interaction of structural elements of the flow supersonic gas jets among themselves in composite jets. When performing the work, various methods allowing to model gas-jets flows and processes are considered. To solve the problem method of structured- element modeling of gas-jet processes was chosen [1–4]. This method focused on the creation of engineering methods for calculating launch gas-dynamics problems. The scope of application of the method can cover not only space roket, also civilian industry is in part where they face the problems of jet flow. For example with the need to improve the reliability of products, their strength and metal characteristics. The direction of subsequent theoretical and experimental research, which determine the development of the structural-element method, are determined and clarified.
An Extra Security Measurement for Android Mobile Applications Using the Fingerprint Authentication Methodology
Authors: Algarni Mohammad
Published: December 2023

This research discusses the development of an Android application through the integration of fingerprint recognition technology for user authentication as a way of improving security in the system. The app serves as an additional security layer, requiring users to verify their identity before gaining access to any installed applications on their Android device. The use of technologically developed devices with fingerprint scanners that have the capacity for analyzing biological traits facilitates a strong user verification process. The process makes use of a fingerprint previously registered by the user to authenticate user legitimacy, hence providing an efficient authentication process. A set of metrics was introduced and verified against a legacy system, proving that the proposed system surpasses the legacy system. This new approach offers the advantage of serving as an alternative to using PIN numbers or pattern unlocking on Android smartphones.
AI in the Era of Fakes and Deepfakes: Risk of Fabricated Photographs and Identities in Academic Publishing
Authors: A. Teixeira da Silva Jaime
Published: December 2023

Academic publishing has entered an era of fake, including fake authors who are either real entities using fake credentials, or totally concocted personalities that give the impression of real humans. Both can be achieved via the use of artificial intelligence (AI) and software that is capable of completing such a task, and ultimately a deepfake is created. The creation of fictitious deepfakes, even more so when assisted or driven by AI, allows creators to not only establish a fake image or photo, but also embed it within a fake context (e.g., profile). For whatever reason, there are risk of deepfakes during manuscript submission and the publication process, as well as on academic social network sites, like ResearchGate, but are academics, journals and publishers sufficiently prepared to detect them?.

Published: December 2023

This study explores the potential effects of different combinations of growth-seeking strategies on performance in SMEs during long times of economic boom and crisis. Our hypotheses are tested on a representative sample of Spanish SMEs between 1994 and 2014. During these years Spain suffered one of the periods of greatest economic stability/growth in recent years (1994-2008), followed immediately by a period of severe crisis (2009-2014). Using dynamic panel data models, our findings reveal that four combinations exhibit a positive and statistically significant effect on performance in times of economic boom: a related product strategy combined with low, moderate, or high levels of internationalization, and an unrelated one combined with a moderate level of internationalization. Meanwhile, we find only two combinations with a positive impact on SME performance in times of crisis: a related product strategy combined with low and moderate levels of internationalization, respectively

Published: December 2023

No verão austral de 1994 a 2019, as anomalias do nível do mar em Santos/SP filtradas na frequência de corte de 28 horas apresentaram tendência linear de +0,00002 m/ano, média de 0,02382 m e variabilidade interanual. Os valores acima da média +2 desvios-padrão ocorreram entre 11 a 22 de fevereiro/2018 concomitantemente a alagamentos registrados nessa Cidade pela Defesa Civil local.  Esse período, definido como o Dia 0, foi selecionado para investigação da influência do vento em superfície nesses valores. Quatro dias antes houve a presença anômala de um anticiclone transiente centrado em 49˚W; 35˚S e um ciclone extratropical em 34˚W;34˚30’S associado a um sistema frontal orientado no sentido noroeste-sudeste desde a costa norte do Sudeste até oceano adjacente. Pela interação entre os centros de alta e baixa pressão, os ventos em superfície confluíram de 3 a 4 m/s mais intensos e com direção anômala de sul. Isso favoreceu o empilhamento seguido do aquecimento anômalo da superfície oceânica na costa de Santos/SP. No Dia 0, o anticiclone transiente se enfraqueceu migrando para noroeste em direção ao continente, enquanto o ciclone se intensificou migrando para 37˚W;34˚S. Os ventos confluíram de sudoeste reforçando a sobre-elevação do nível do mar extrema na cidade. O transporte de umidade oceânica por esses ventos reduziu a pressão ao nível do mar ocasionando chuva acima da média desde 2 dias antes e durante o Dia 0 sobre Santos/SP. A metodologia apresentada pode ser aplicada operacionalmente para o diagnóstico da evolução das anomalias meteo-oceanográficas ajudando em futuros Planos Preventivos.

Published: December 2023

A região do Nordeste brasileiro destaca-se pela grande riqueza de espécies vegetais. Dentre as quais, as cactáceas representam um dos grupos de maior ocorrência e relevância. As diferentes espécies e variedades de cactos têm sido explorados com diferentes finalidades e apresentam composição nutricional importante para alimentação humana e animal. Assim, apesar de existirem diversas pesquisas que envolvem os atributos e as possibilidades de utilização de numerosas cactáceas na alimentação animal e humana, são escassos os estudos que se propõem a sistematizar tais conhecimentos.  Portanto, o objetivou-se realizar uma revisão sistemática acerca das principais espécies de cactáceas encontradas na região Nordeste do Brasil, bem como conhecer as possibilidades de uso e a composição química das plantas pertencentes a este grupo. Para tanto, a metodologia desta revisão baseou-se em periódicos disponíveis em bases de dados como Google Scholar, SciELO e ScienceDirect. Verificou-se que os estados do Ceará, Pernambuco e Sergipe são os que mais desenvolvem estudos com cactáceas, com níveis de citações de 25,49%, 23,53% e 23,53%, respectivamente. Nestes estudos, 16 gêneros de cactáceas são abordados, em especial o Pilosocereus. Além disso, foi observado que diferentes partes das plantas são utilizadas pela população, principalmente na área de forragem animal (16,96%), alimentação humana (14,29%) e ornamentação (12,50%). Além disso, evidenciou-se que a composição bromatológica destas plantas depende de diferentes fatores, tais como fase fenológica, espécie e adubação. Assim, conclui-se que o Nordeste brasileiro se configura como um centro de diversidade de cactáceas e que estas apresentam grande potencial para uso local.

O objetivo deste trabalho é avaliar os índices médios de vegetação NDVI, SAVI, NDMI e EVI para o Município de Francisco Beltrão em 16/12/2018 e de 24/12/2021. A utilização destes índices neste estudo é para identificar os impactos de uma estiagem que ocorreu no município na safra 2021/2022. De forma geral, o NDVI apresentou bom desempenho na avaliação dos efeitos da estiagem. Para o NDMI a estiagem provocou diminuição dos teores de umidade na média, mediana e maioria para as formas de uso de Reflorestamento, Floresta Nativa e Lavoura de alta densidade, Pastagem, Lavoura de média densidade e Lavoura em estágio inicial. O NDMI, para as formas de uso desprovidas de cobertura vegetal são: Água e Solo exposto, assim, os valores da água (média, mediana, mínimo e maioria) em 16/12/2018 e em 24/12/2021 deveriam ser todos valores positivos e próximos de 1, mas em função da presença de sedimento, provavelmente a presença de algas e por serem águas rasas, os teores de umidade da média e mediana deram positivo entre 0,3652 e 0,3858, o que caracteriza índice de desempenho mediano na avaliação da estiagem. Entretanto, o índice SAVI, mesmo tendo conseguido identificar o estresse hídrico nas formas de uso do solo de 16/12/2018 para 24/12/2021 não se mostrou adequado para avaliar a diferença do vigor vegetativo para na área de estudos. De forma geral o EVI apresentou desempenho médio na avaliação do impacto da estiagem em 24/12/2021, isso nas diferentes fomas de uso do solo no município de Francisco Beltrão.

Published: December 2023

A caracterização morfométrica de uma bacia hidrográfica se configura como uma técnica fundamental para a compreensão de seu regime hidrológico, subsidiando a gestão e planejamento dos recursos hídricos. Esse tipo de caracterização pode ser determinado pelo processamento de Modelos Digitais de Elevação (MDE) em um Sistema de Informações Geográficas (SIG). Dessa forma, o presente estudo teve como objetivo analisar as características morfométricas da bacia hidrográfica do rio Duas Unas, em Pernambuco, a partir de um MDE proveniente de perfilamento a laser aerotransportado (LiDAR). Esse tipo de dado espacial foi submetido a técnicas de pré-processamento, tais como reprojeção do seu sistema de referência de coordenadas para UTM (fuso 25S) e do seu sistema geodésico para SIRGAS 2000, bem como exclusão de seus pixels espúrios. Esses procedimentos possibilitaram a delimitação automática da bacia, a definição de sua rede hidrográfica e, consequentemente, a obtenção de seus parâmetros morfométricos. Pelos resultados foi constatado que a bacia do rio Duas Unas apresenta um formato alongado, compreende uma rede hidrográfica com um sistema de drenagem regular e seu canal principal tende a ser sinuoso e apresenta baixa declividade. A concepção dos resultados alcançados nesse estudo permite o entendimento do comportamento hidrológico da bacia de maneira consistente, podendo ser utilizados para um planejamento ambiental adequado.

A região metropolitana de Belém no estado do Pará possui poucos parques urbanos, dos quais os mais importantes são Parque Estadual do Utinga (PEUt) e a Área de Proteção Ambiental Estadual de Belém (APA Belém). A maioria dos estudos botânicos nessas unidades conservação não levaram em consideração os padrões de estrutura e florística entre as fitofisionomias. O objetivo deste trabalho foi realizar inventário florístico para comparar a abundância de indivíduos e a riqueza e composição de espécies entre as fitofisionomias. Os dados do inventário foram coletados em 2018 e 2019 em campinarana, floresta de terra firme, floresta de igapó e floresta de várzea. Foram registrados 1.085 indivíduos, em 57 famílias e 162 espécies. Houve variação significativa do número de indivíduos e de espécies entre as fitofisionomias. A campinarana obteve menor abundância de indivíduos e de espécies. Houve nítida separação da composição de espécies. Existe variação da diversidade beta (habitats) entre os tipos de vegetações e esta que deve considerada nas ações de manejo dessas unidades a fim de proteger a maior parte da flora.

Published: December 2023

The municipality of Irauçuba, located in the Semiarid region of Ceará, Brazil, has faced the effects of desertification resulting from the scarcity of rainfall. This study aimed to assess the progression of desertification in the area from 2003 to 2020, using climatic and biophysical data collected during this period. We used supplementary data from automatic meteorological stations operated by the National Agency of Water and Basic Sanitation to determine the rainfall anomaly index of the historical series. Additionally, we performed annual scale validation of the CHIRPS data using statistical indicators such as Pearson Correlation Coefficient, Mean Error, Percentage BIAS, and Root Mean Square Error. Subsequently, we analyzed land cover and land use changes over the 17 years (2003-2020) in the municipality by processing CHIRPS, MODIS product (MOD16A2 and MOD11A2), and MapBiomas data in the Google Earth Engine digital platform and QGIS software. We analyzed land cover and land use changes using MapBiomas data. Finally, we analyzed the aridity index for the same 17-year period. The research findings revealed a significant correlation between rainfall and biophysical parameters, with the lowest aridity index of 0.255 observed between 2012 and 2014 and the highest of 0.464 between 2018 and 2020. The area's susceptibility to the desertification process was classified as high, which is consistent with the Semiarid climate of the region. The methodology employed during the research proved to be a sustainable technology of low economic cost and telling and easy access, which enabled the creation of a scientific contribution for future works in the region, besides being able to add knowledge for studies of environmental degradation.

O SUPer (Sistema de Unidades de Resposta Hidrológica do Estado de Pernambuco, Brasil) foi desenvolvido através de uma grande parceria entre universidades e órgãos públicos para apoiar decisões econômicas e políticas, baseadas em simulações em tempo real, e de curto, médio e longo prazos, com a Ferramenta de Avaliação de Solo e Água (SWAT). Para que o sistema SUPer funcione efetivamente, ele precisa de uma grande quantidade de bacias calibradas, de forma a abranger o comportamento hidrológico de todo o estado de Pernambuco, incluindo características físicas, hidrológicas, de relevo e uso da água. Nesta pesquisa, construímos e calibramos um modelo hidrológico integrado do Estado de Pernambuco utilizando o programa Soil and Water Assessment Tool (SWAT), a fim de subsidiar o sistema SUPer e torná-lo uma ferramenta ativa para a Agência Pernambucana de Águas e Clima (APAC), contribuindo para o processo de planejamento e gestão dos recursos hídricos do estado. Para isso, selecionamos oito bacias do Estado de Pernambuco: Goiana, Sirinhaém, Capibaribe, Una, Mundaú, Pajeú e Brígida. Diferentes componentes dos recursos hídricos foram simulados e as características dos reservatórios foram consideradas a nível da Unidade de Resposta Hidrológica (HRU). Os recursos hídricos foram quantificados a nível de sub-bacia com intervalos de tempo mensais. Além disso, o SWAT-CUP foi usado com uma abordagem semiautomática (SUFI2) para análise de sensibilidade e para os procedimentos de calibração e validação. Em uma análise geral, foram observados ajustes e desempenho estatístico satisfatórios entre os valores medidos e simulados de vazão durante os processos de calibração e validação na maioria das bacias analisadas, onde a bacia do Rio Brígida apresentou o pior desempenho e a bacia do Rio Goiana apresentou o melhor desempenho entre as oito bacias analisadas.

Published: December 2023

Kursi roda merupakan suatu fasilitas penyandang cacat kaki. Orang yang tidak bisa melakukan aktivitasnya dengan kaki, sangat membutuhkan kursi roda ini untuk melakukan mobilitas. Salah satu kegiatan yang dilakukan secara rutin ialah naik dari/ke kursi roda ke/dari tempat tidur. Karena keterbatasan kaki yang lemah, maka tidak memungkinkan pasien utuk berpindah dari/ke kursi roda ke/dari tempat tidur. Perlu bantuan seseorang/perawat untuk menggendong pasien tersebut. Akan tetapi, bila itu dilakukan terus menerus setiap hari, dan juga apabila pasien tersebut berat, maka hal tersebut bisa mencederai perawat tersebut. Oleh karena itu, dirancang suatu alat angkut/angkat dari/ke kursi roda ke/dari tempat tidur, yang bisa membantu perawat memindahkan pasien. Penelitian dimulai dengan mengumpulkan data dan spesifikasi kursi roda ( bentuk dan dimensi : lebar, panjang, tinggi alas dan kursi roda keseluruhan ), bahan pendukung untuk alas alat angkut pasien yang kuat dan data antropometri ( dimensi tubuh manusia yang akan merepresentasikan dimensi pasien ). Dari data-data tersebut dipilih dan dirancang sebuah fasilitas yang memudahkan perawat memindahkan pasien dari/ke kursi roda ke/dari tempat ridur. Aspek yang diperhatikan ialah ergonomic, yaitu aspek kenyamanan, aspek keamanan dan aspek kemudahan pemindahan pasien. Hasil dari rancangan berupa alas pemangku dan alat pengangkut.

Authors: Gabriela Gabriela , Halim Winda
Published: December 2023

Apotek X merupakan salah satu apotek di Bandung. Pencatatan transaksi penjualan dan persediaan barang di Apotek X dilakukan secara manual, pekerja sering melakukan kesalahan pencatatan transaksi penjualan atau stok obat, kesalahan menghitung harga yang harus dibayar pembeli atau pengembalian uang. Hal ini menyebabkan perbedaan jumlah (uang atau stok obat) dalam laporan dengan jumlah secara fisik. Penelitian ini dibuat dengan tujuan memberikan usulan aplikasi pencatatan transaksi penjualan dan persediaan barang dengan pendekatan user centered design (UCD). Terdapat dua alternatif, penggunaan kedua aplikasi dapat dilakukan pemilihan atau digunakan secara bertahap. Kedua aplikasi digunakan oleh 5 pengguna di Apotek X. Alternatif pertama, aplikasi yang tersedia di pasaran, yaitu aplikasi point of sales (POS) X, dilakukan pengujian pengalaman menggunakan kuesioner user experience questionnaire (UEQ). UEQ memberikan hasil positif dan termasuk dalam kategori excellent (pengalaman pengguna baik). Uji kepuasan pengguna menggunakan kuesioner system usability scale (SUS), dengan nilai 68 (pengguna cukup puas). Alternatif kedua, rancangan user interface aplikasi yang dinamakan Aplikasi Apotek. Aplikasi Apotek hanya dilakukan uji SUS, karena aplikasi tersebut dibuat sampai tahap prototype. Nilai SUS yang diperoleh adalah 72 (pengguna puas). Aplikasi POS X dapat digunakan secara mudah dan cepat, tetapi tidak fleksibel. Sedangkan Aplikasi Apotek lebih fleksibel, tetapi butuh waktu dalam penerapannya.

Facilitators of Nurse Practitioners’ Transition to Practice: An Integrative Review
Authors: Lloy Breanna , Peter Elizabeth , Parry Monica , Mitchell Carolyn
Published: December 2023

Aim: To review the literature and identify the facilitators that help new graduate nurse practitioners (NP) transition to practice.
Background: The NP profession originated in the United States in the 1960s and followed in the same decade by Canada. Although the NP profession has existed for more than 50 years, struggles still exist in their full implementation to the health care system. These challenges include recruitment and retention, healthcare setting support, role clarity, public awareness, legislation and regulation, and funding. Focusing on retention, NPs have double the amount of turnover in comparison to their physician counterparts. This high turnover rate is often attributed to the challenges NPs face during their transition to practice as new graduates.
Methods: An integrative literature review guided by the framework proposed by Whittemore and Knafl. Data sources included: CINAHL, Medline, and Web of Science. Twenty-seven studies met the inclusion criteria and were assessed using the Mixed Method Appraisal Tool. Findings from the studies were obtained and analyzed using themes.
Findings:  Five themes were identified: (1) fellowship or orientation/onboarding programs, (2) mentorship, (3) prior registered nurse experience, (4) autonomous practice, and (5) communities of practice. This review revealed the complexity and interconnection of facilitators to transition.
Conclusion: The NP role continues to expand globally; it is imperative that facilitators to transition are implemented to improve NP retention and address the education to practice gap.

The effect of financial leverage on firm profitability and working capital management in the Asia-Pacific Region
Authors: Deshpande Anya
Published: December 2023

Aim: The main aim of this article is to examine the impact of financial leverage on firm profitability and working capital management of Asia-Pacific (APAC) firms listed in the United States and the United Kingdom.
Design / Research methods: The regression analyses are conducted with panel data over the period of 2013-2022 using the Ordinary Least Squares method. Historical financial data has been obtained by using Refinitiv Eikon. In addition to quantitative research, this study also provides case examples.
Conclusions / findings: The findings reveal that for APAC firms listed internationally, financial leverage has a negative relationship with firm profitability and a positive relationship with working capital levels. The study emphasizes the complex nature of financial leverage as a double-edged sword, capable of shaping the trajectories of APAC firms navigating the international business arena.
Originality / value of the article: Although the effect of financial leverage on firm profitability has been researched before, it has not been researched on the Asia-Pacific region as a whole, specifically for the companies that are listed internationally. Furthermore, the effect of financial leverage on working capital management is scant overall and has rarely been examined distinctively, especially in this particular geographical region.
IPO underpricing and overpricing and long-term firm performance in the Netherlands, United Kingdom, France, Sweden, and Italy: learning from three Dutch IPOs
Authors: Drooduin Timothy
Published: December 2023

Aim: This research contributes to the study of the relationship between initial public offering (IPO) under- and overpricing and long-term firm performance as measured by net income.
Research methods: Using ordinary least-squares regressions, an international sample of 444 IPOs from the United Kingdom, Sweden, France, Italy, and the Netherlands for the period 2013–2017 is analysed. The data was extracted from the Eikon Refinitiv database. Further, an in-depth analysis of three Dutch IPOs by six interviews with five (former) management members and one investment banker is conducted.
Conclusions: The results show that the more profitable a firm is in the long run, the likelier positive initial stock returns move towards zero after the first trading day. The case studies support these findings and the concept of asymmetric information between market participants can offer a partial explanation. Additionally, as firms operating in the industrial and healthcare sector grow larger, the offer price tends to be closer to the overall market demand. Nonetheless, no significant relationship is found between initial stock return and net profitability for other industries. While the country analysis also displays no significant relationship, underpricing is more prevalent in the United Kingdom than in the other sample countries.
Originality: This article combines a full-fledged quantitative study with a full-fledged qualitative study on one of the most perilous corporate finance milestones, that is, the complex transformation from a private to a public company through a stock market listing.
Limitations: The sample composition skews towards underpriced IPOs. Also, although the notion of reverse causality is discussed based on the views of interviewees, no quantitative evidence is provided.
