Respostas municipais ao problema de habitação social na Região Metropolitana de Curitiba
Authors: Moreira Tomás Antonio , Leonelli Gisela Cunha Viana , Nascimento Neto Paulo
Published: May 2024

A Região Metropolitana de Curitiba é uma das principais regiões metropolitanas do País que terá elevado incremento populacional nos próximos anos. Dados estaduais mostram que esse incremento não ocorrerá no município sede, e sim naqueles mais frágeis socialmente e com maiores problemas ambientais. As políticas habitacionais empreendidas atualmente estão focadas em municípios, desconsiderando as relações intermunicipais e a distribuição populacional, bem como o movimento pendular entre os municípios. Objetiva-se analisar as limitações e os possíveis equívocos das políticas habitacionais segmentadas. Destarte, procura-se discutir as condições habitacionais da Região Metropolitana de Curitiba a partir dos planos habitacionais. Os resultados obtidos evidenciam a prática recorrente da abordagem das políticas habitacionais no País, bem como um descolamento dos valores e ideais adotados na práxis da gestão pública, o que conduz ao questionamento sobre a real contribuição das propostas para reverter as condições habitacionais existentes.
Enigma do capital e as crises do capitalismo
Authors: Gaspar Ricardo Carlos , Somekh Nadia
Published: May 2024

O último livro do geógrafo norte-americano David Harvey aborda uma dimensão essencial da economia mundial contemporânea, cujos desdobramentos estão na base das crises que o sistema vivencia desde os anos 1990. Refere-se ao fato dos capitalistas estarem sempre produzindo excedentes financeiros, os quais necessitam, por força da competição, encontrar saídas para sua absorção na forma de investimentos lucrativos. O problema é que essa expansão ocorre em ritmo composto, a uma taxa aproximada de 3% ao ano. Então se trata de encontrar aplicação rentável para massas crescentes de recursos, levando investidores a exercitar de forma frenética seus poderes de “destruição criativa” no sentido de sempre alavancar novas oportunidades de investimento.

Authors: Leal-Hernández Olga , Caballero-Barrantes Mercedes
Published: May 2024

Según la Sociedad Española de Alergología e Inmunología Clínica (SEAIC), las enfermedades alérgicas afectan a un 30% de la población española. La alergia ocupa la sexta posición dentro de las diez enfermedades o problemas de salud que la población de 15 años o más refiere padecer con mayor frecuencia (13,37%), según la Encuesta Europea de Salud en España (EESE) 2014, realizada por el Instituto Nacional de Estadística (INE).Desde la primera inoculación subcutánea por Leonard Noon en el año 1911 de un extracto de Phleum pratense a pacientes polínicos, se han publicado múltiples estudios controlados que demuestran que la inmunoterapia alérgeno específica es el único tratamiento capaz de modificar el curso natural de la enfermedad alérgica, reduciendo significativamente la severidad de la enfermedad y el consumo de medicación, así como mejorar considerablemente la calidad de vida. En el presente estudio se han recogido datos de 46 pacientes mayores de 14 años que reciben inmunoterapia, con pauta rush, en una consulta de alergia privada de la ciudad de Cáceres para conocer cuál es el alérgeno frente al que más se vacunaban y su seguridad, obteniendo un mayor porcentaje en “Mezcla de gramíneas 100%”, que representa un 47,83% de los estudiados, seguida de “Mezcla gramíneas 50% Olea europaea 50%” con un 28,26% y se demuestra que la inmunoterapia subcutánea es un método seguro y adecuado para el tratamiento de la alergia.

Published: May 2024

Background: Second generation antipsychotics (SGAs) are strongly associated with accelerated body weightgain resulting in overweight and obesity in patients with severe mental illness (SMI). Evidence found that lifestyleinterventions used behavioral techniques to improve dietary habits and increase physical activity can reduce the increasein patients’ body weight and BMI. Methods: Randomized Controlled Trial (RCT) on 54 patients with severe mental illnesswere randomized with 27 patients joined in the Lifestyle Intervention group (LIP) and 27 patients in treatment as usual group(TAU) from September/2018 to October/2019. The intervention group attended the educational talks on medication, dietcontrol and physical exercise and use of a daily record. Result: After twelve months, the LIP presented a decrease of 1.25kg(CI 95% -0.73 to 3.24) and treatment as usual TAU presented with a significant increase of 1.65kg CI 95% -2.84 to -0.45)(p=0.009). The BMI of the LIP showed a decrease of 0.51kg/m2 (CI 95% -0.29 to 1.33) and the TAU presented an increaseof 0.66kg/m2. Conclusion: The TAU shows a significant increase of body weight while the LIP group had a decrease inbody weight under the Life Intervention program. This study was not intended for patients to reduce body weight, rather toprevent their body weight to increase and enhance their quality of life through understanding physical health, exercise anddietary habit.

Published: May 2024

El impacto de la pandemia de Covid-19 se ha narrado a partir de las cifras de morbimortalidad en muertes, días de enfermedad o discapacidad. Pero los censos de morbimortalidad no alcanzan a describir la totalidad del impacto de la enfermedad en la vida de pacientes, familiares y profesionales de la salud. Este trabajo, de naturaleza cualitativa, persigue analizar las experiencias de enfermeras que estuvieron en primera línea durante la primavera de 2020. Se realizaron entrevistas semiestructuradas a un total de 19 participantes, desde un enfoque empírico de naturaleza fenomenológica y un análisis temático de los relatos. El estudio se realizó en la ciudad de Cáceres del 1 de septiembre de 2020 y el 10 de enero de 2021. Los participantes fueron reclutados a través de un muestreo intencional y de bola de nieve hasta la saturación de la información recabada. Cinco grandes categorías temáticas analíticas emergen: 1) Condiciones laborales; 2) Impacto en el ámbito emocional; 3) Impacto en el ámbito social; 4) Estrategias de afrontamiento; 5) Identidad profesional. Los relatos de experiencia constituyen un tipo de evidencia imprescindible con la que analizar las relaciones entre contexto laboral y experiencia, ofreciendo material para poder examinar carencias y definir planes de mejora.

Published: May 2024

This study aimed to investigate plant diversity, traditional utilization, and create a web-based application for sustainable community-based utilization management of the small-scale Nong Sakae Community Forest, Dan Chak sub-district, Non Thai district, Nakhon Ratchasima, Thailand. Our results revealed 29 plant species belonging to 21 genera. Notably, the Fabaceae family dominated the forest and comprised seven species, including two recognized as invasive species. Diversity indices revealed a moderate level of species diversity, with Shannon–Weaver (H’) and Simpson's diversity indices at 1.7844 and 0.6076, respectively. Species richness indices involving Margalef and Menhinick were 4.3805 and 1.1869, respectively, whereas evenness was 0.5414. The most ecologically significant species was Vietnamosasa ciliata A. Camus, which exhibited the highest importance value index (IVI) at 63.4321. Furthermore, the community forest served as a sustenance for the local community for food, medicinal herbs, and timber, emphasizing its significance in supporting their livelihoods. However, this forest has faced encroachment, forest fires, and littering. A web-based mapping system has made forest information more available and understandable, enabling informed decision making and effective forest management. This study offers valuable insights into biodiversity and ecosystem functions in the Nong Sakae Community Forest, emphasizing the need for collaboration and effective policy development in conservation efforts.
Investigating the government’s role in the boom-and-bust cycles of the housing market
Authors: Meshkini Abolfazl , Nejati Sadegh , Alipour Somayeh
Published: May 2024

Governments intervene in the housing market via implementing various monetary, fiscal, foreign exchange and credit policies. By this, the housing market undergoes cycles of boom and bust as well as significant swings in value added and housing prices. Therefore, the main goal of this research is to consider the effect of the government’s change on the monetary and financial policy’s impact on the business cycles of the housing sector during the period of 1978–2020. On the other hand, we estimate the impact of monetary and fiscal policies on housing business cycles concerning government’s change. To calculate housing business cycles (boom and busts), the housing value added were initially de-trended using the Hodrick–Prescott filter. This paper takes a novel use of the threshold regression model with government’s change as threshold variable. According to the study’s findings, there are three threshold effects (two threshold levels or three regimes) of monetary and fiscal policy on housing business cycles. For instance, the money supply coefficient in the first regime was −1.68, indicating that the effect of monetary policy in this regime is countercyclical. in the second and third regimes, it was 0.19 and 0.03, respectively; indicating its alignment with the housing business cycle. Regarding the estimated models, we may derive several interesting conclusions. In first regime, the money supply is countercyclical and government expenditure is pro-cyclical. This means that monetary policy exacerbates recession and fiscal policy weakens it. in the second and third regimes, the money supply is pro-cyclical and government expenditure is countercyclical. As a result, while formulating their monetary policies, governments should give the housing sector more consideration. Additionally, when putting this policy into practice, the housing sector has to be carefully examined.
Scanning electron microscopic and morphological studies on in-vitro derived callus of low-chill peach (Prunus persica L. Batsch)
Authors: Bisht T. S. , Rawat Laxmi , Singh P. N. , Chakraborty B. , Visen A.
Published: May 2024

In this investigation the effect of collection seasons of explants (winter, spring and summer), type of explants (leaf disc and intermodal segments) and length of explants (0.5, 1.0 and 1.5 cm) for callusing in low-chill peach were standardized. The maximum callus induction (97.78%) in the low-chill peach was obtained from the intermodal segments of 0.5 cm in length used as an explant collected during spring season. The structural changes on the surface of the callus (5–7 weeks old yellowish green compact callus) during the progress of somatic embryogenesis of low-chill peach from the both intermodal segment as well as leaf disc derived callus were also examined with the use of scanning electron microscope (SEM). The SEM studies indicated that callus derived from internodal segment explant had the highest frequency of somatic embryos than callus from leaf discs. The SEM investigation, also demonstrated the sequential events/steps leading to low-chill peach somatic embryogenesis which was originating from somatic embryo mother cells through one unicellular pathway. Two types of calli were morphologically distinguished in both leaf disc and intermodal segment generated callus and these were the compact, well organized yellowish green embryogenic callus, containing large number of small, rich cytoplasmic, starch containing meristematic cells and soft and unorganized non-embryogenic callus containing sparsely cytoplasmic, vacuolated, and large cells devoid of metabolic reserves. The present SEM studies clearly demonstrated that somatic cells from peach explants generated callus could develop into fully differentiated somatic embryos through the characteristic embryological patterns of differentiation.

Additivity of multiplicative generalized Jordan maps on triangular rings
Authors: Aziz Sk , Ghosh Arindam , Prakash Om
Published: May 2024

This paper presents three different conditions for the additivity of a map on a triangular ring $\mathcal{T}$. First, we prove a map $\delta$ on $\mathcal{T}$ satisfying $delta(a_1b_1+b_1a_1)=\delta(a_1)b_1 +a_1 \tau(b_1)+\delta(b_1)a_1 + b_1\tau(a_1)$ for all $a_1,b_1\in \mathcal{T}$ and for some maps $\tau$ over $\mathcal{T}$ satisfying $\tau(a_1b_1+b_1a_1)=\tau(a_1)b_1+a_1 \tau(b_1)+\tau(b_1)a_1+b_1\tau(a_1)$, is additive. Secondly, it is shown that a map $T$ on $\mathcal{T}$ satisfying $T(a_1b_1)=T(a_1)b_1=a_1T(b_1)$ for all $a_1,b_1\in \mathcal{T}$ is additive. Finally, we show that if a map $D$ over $\mathcal{T}$ satisfies $(m+n)D(a_1b_1)=2mD(a_1)b_1+2na_1D(b_1)$ for all $a_1,b_1\in \mathcal{T}$ and integers $m,n\geq 1$, then $D$ is additive.
Generalized splittings of monomial ideals
Authors: Bouchat Rachelle R. , Brown Tricia Muldoon
Published: May 2024

Eliahou and Kervaire defined splittable monomial ideals and provided a relationship between the Betti numbers of the more complicated ideal in terms of the less complicated pieces. We extend the concept of splittable monomial ideals showing that an ideal which was not splittable according to the original definition is splittable in this more general definition. Further, we provide a generalized version of the result concerning the relationship between the Betti numbers.

Authors: Kutt Filip , Sienkiewicz Łukasz , Racewicz Szymon , Michna Michał , Ryndzionek Roland
Published: May 2024

The article presents the Power Hardware in the Loop (PHIL) approach for an autonomous power system analysis based on the synchronous generator model incorporating magnetic saturation effects. The model was prepared in the MATLAB/Simulink environment and then compiled into the C language for the PHIL platform implementation. The 150 kVA bidirectional DC/AC commercial-grade converter was used to emulate the synchronous generator. It was controlled by the real-time simulation control unit with the prepared synchronous generator model incorporating magnetic saturation effects. The proposed approach was validated on the 125 kVA synchronous generator connected to the active and reactive loads of different values for the steady-state and the transient-state performance studies.

Authors: Qiu Hongbo , Gao Wenhao , Duan Shuaishuai
Published: May 2024

To further enhance the speed regulation range of the hybrid excited machine (HEM), the structure of a magnetic ring is optimized using a combination of the magnetic circuit method (MCM) and numerical analysis method in this paper, and a disc magnetic ring (DMR) is proposed. The magnetic density distribution of the proposed disc magnetic ring hybrid excited machine (DMRHEM) is compared to the radial-axial hybrid excited machine (RAHEM), and the superiority of alleviating a saturation problem in the proposed DMRHEM is determined. To improve the power density, the spoke-type permanent magnet (PM) rotor is applied. The influence of the proposed DMR on the HEM is analyzed, and the field adjustment capability of the proposed DMRHEM is better. Based on this, by combining the bypass principle, the analytical expressions for the relations between the rotor pole-pair number and the motor axial length/stator inner diameter (MAL/SID) as well as flux regulation capability are derived to further explore the superiority of the proposed DMRHEM. The influence mechanism of the rotor pole-pair number and the MAL/SID on the proposed DRMHEM is determined. The optimal MAL/SID and pole-pair number are obtained.

Published: May 2024

Dual active full-bridge (DAB) DC–DC converters are widely used in DC microgrids and various fields of power electronics. It has the advantages of high-power density, easy to implement soft switching and bi-directional power transfer capability. Conventional linear controllers have difficulty in meeting the increasing demands for speed and robustness. In this paper, a control strategy based on the Brayton–Moser theory of power shaping is proposed to improve the control strategy of DAB DC–DC converters. The DAB DC–DC converter is modelled and the controller is designed based on the Brayton–Moser power-shaping theory. A simulation of the DAB DC–DC converter is constructed and a comparative analysis is carried out for three control strategies of PI control, passive control and power-shaping Brayton–Moser control under different operating conditions.

Published: May 2024

Incorporating specialization into innovation and entrepreneurship programs has proven to be an effective strategy for advancing this education in higher education institutions. This study firstly proposes the teaching mode of “integration of specialization and innovation” in sports colleges and universities, and on the basis of this, selects the evaluation indexes for the improvement of teaching innovation ability of physical education teachers, and prepares relevant questionnaires. Then, the weights of the indicators of the progress of teaching innovation ability were determined by the CRITIC method. The samples were evaluated and cluster analyzed for the improvement of the teaching innovation ability of physical education teachers. The study indicates that physical education teachers’ overall capacity for teaching innovation is moderate. While their teaching skills are highly developed, their innovation skills are generally lacking, with 75.94% of teachers receiving a medium or poor rating in innovation. Four categories emerged from the analysis: innovative, double-weak, teaching-focused, and teaching innovation. Notably, 66.31% of the teachers excelled either in teaching enhancement or innovation. In addition, physical education teachers’ teaching innovation ability enhancement = 0.452 + 0.258*professional ability + 0.206*teaching environment + 0.184*professionalism + 0.156*professional knowledge. The study is conducive to fully utilizing the potential of physical education teachers and enhancing their teaching innovation ability in colleges and universities.

This study examined how fermentation and roasting alter the amino acid profile of infant food created from mixtures of sorghum and soybean. Sorghum and soybean were fermented, roasted and both fermented and roasted before milling into flours. Untreated sorghum and soybean flours were also produced to serve as the control. Except for the control samples, each blend had 5% malted sorghum flour added. Weaning foods were prepared with these blends, and their amino acid profiles were determined. The contents of essential amino acids, including histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine, ranged from 2.03 to 2.48 g/100g, 3.39 to 5.22 g/100g, 8.16 to 11.21 g/100g, 4.18 to 6.38 g/100g, 1.45 to 2.41 g/100g, 4.22 to 6.34 g/100g, 3.41 to 5.86 g/100g, 2.98 to 4.30 g/100g, and 4.01 to 6.33 g/100g, respectively. The contents of non-essential amino acids, including alanine, arginine, aspartic acid, cystine, glutamic acid, glycine, proline, and serine, varied between 3.31-6.13 g/100g, 4.93-7.32 g/100g, 10.23-14.33 g/100g, 1.38-2.35 g/100g, 13.64-16.84 g/100g, 3.99-6.35 g/100g, 3.59-5.34 g/100g, and 2.94-4.88 g/100g, respectively. The fermentation and roasting processes were found to significantly enhance the amino acid content of weaning foods with inconsistent effects. Therefore, optimizing these conditions is recommended for weaning blends to maximize health and nutritional benefits for infants and young children.

In April 2021, the government of Sri Lanka abruptly banned chemical fertilizers and other agrochemicals in a bid to safeguard the country’s agricultural industry, particularly its farmers and consumers, from various health and environmental concerns. Therefore, it is critical to assess the impact of prohibiting chemical fertilizers and other agrochemicals on the smallholder tea production in the country. Additionally, understanding the smallholders’ awareness of agrochemicals and their attitudes toward transitioning to organic farming is essential, as these factors hold significant importance for various aspects of the economy. The Ratnapura district was selected as the research area, owing to its extensive tea cultivation across numerous Divisional Secretary (DS) divisions. For this study, a sample of 120 tea smallholders was randomly chosen from three DS divisions (Balangoda, Opanayaka, Imbulpe), representing the entire district, who supply green leaves to the ABC tea factory in Balangoda. Research data were collected through a field survey conducted between September and November 2022. Descriptive statistics and paired t-tests were employed for data analysis. Additionally, the costs incurred for chemical fertilizers and other agrochemicals, the total cost of production, as well as tea production before and after the implementation of the fertilizer policy, were analyzed using paired t-tests. The results obtained indicate that the majority of tea smallholders possess a high level of education, with most owning tea lands ranging from 0.5 to 1.0 acre. Furthermore, a vast majority of them demonstrate understanding of both the positive and negative aspects of agrochemicals. Notably, the analysis reveals a significant increase in the cost of chemical fertilizers and other agrochemicals, as well as the total cost of production, following the implementation of the fertilizer policy. Conversely, tea production has shown a significant decrease. Moreover, farmers express willingness to transition gradually from conventional farming practices if suitable alternatives are available. However, they currently face a myriad of challenges due to the lack of effective alternatives for chemical fertilizers and agrochemicals. Consequently, there is a pressing need to identify and implement better alternatives to address their concerns.

Land use in arid and semi-arid regions is a serious challenge for sustainable production, owing not only to drought and climate change but also to water availability. Irrigated perimeters in these regions are subject to secondary salinization that negatively impacts soil quality and agricultural productivity. Monitoring and diagnosing the extent of soil contamination requires a more innovative approach to optimize rehabilitation of affected areas. In the present study, diagnosing of saline soil degradation is conducted by using two key indicators: electrical conductivity of saturated paste extract (ECe) and saturated hydraulic conductivity (HCs). The results of the study reveal that the value of ECe in 85% of the Lower Chellif Plain area (north-west Algeria) is ECe < 2 dS m−1, while 78% of the area is moderately permeable. These findings underscore high spatial variability in salinity distribution, indicating that the process of salinization has not yet reached a critical stage. Furthermore, it is concluded that ECe and HCs are appropriate indicators for diagnosing salinity of soil in relation to its structural and permeability characteristics.

Aim. This study aimed to investigate how nursing students utilised the “DiagNurse” mobile app to assess patient health conditions during their clinical apprenticeships.

Material and methods. This prospective, quasi-experimental post-test study included a convenience sample of 62 undergraduate nursing students. In the course of the work, they utilized paper-based measurement scales (first measurement) and the mobile app (second measurement) to assess patient health conditions during clinical practice. In total, 432 clinical condition assessments were performed on patients in the first measurement and 432 in the second measurement. Following the clinical assessment, two types of post-tests were employed to ascertain the usability of the mobile app: quantitative testing using the System Usability Scale and qualitative testing.

Results. The mean SUS score was 80.2 (SD 15.67). The majority of the students agreed that the utilisation of the mobile app to assess a patient’s health condition is faster (M=3.21) and more convenient (M=3.16) than the use of paper-based scales and questionnaires. On a 0–10 scale, the study participants rated it as “highly recommended” (M=8.03) for fellow nursing students or practicing nurses.

Conclusions. Although the “DiagNurse” mobile app was considered a suitable tool for learning clinical patient assessment, the students also proposed some improvements to the app’s design.
