Authors: Nazir Arnengsih , Putri Salsabila S S , Bashari Muhammad Hasan
Published: September 2023

Coronavirus disease 2019 (COVID-19) causes various clinical manifestations during acute infection and at the post-acute phase with persistent symptoms called long COVID. It occurs in mild and moderate to severe cases which require hospitalization. In patients needing hospitalization, especially intensive care unit admission, the risk of long COVID increases. Many hospitalized patients exhibited more symptoms in 60 days after the illness than non-hospitalized patients. This review aimed to identify the clinical and functional outcomes in COVID-19 survivors after hospitalization. The articles in the PubMed database published in 2019-2021 were reviewed and found 20 be eligible. The clinical outcomes were the appearance or persistence of general and multi-organ symptoms, nutritional disorders, and decreased lung function. The functional outcomes found were decreased muscle strength, physical, psychological, and cognitive functions, increased disability and dependencies, as well as decreased vocational status and quality of life. The incidence of each outcome could not be determined due to the variety of methods used to examine and present outcomes. To conclude, COVID-19 causes long-term clinical and functional outcomes that need to be identified to prevent and manage long-term physical and functional disorders.

Authors: Hidayah Ana Miftahul , Riyadi Abdul Kadir
Published: September 2023

Gender equality is a Western concept that is well applied in its culture to humanize women, for the dark history experienced by women during the Middle Ages which had an impact on traumatic attitudes towards men and religious statements, and with this sensitive nature, feminist groups oppose statements that are valued gender bias, especially in the holy texts, by adhering to the concept of 'gender equality' which means equal as a whole. However, the results of applying the concept of gender equality to the Qur'an state that the statement of the Qur'an and the interpretation of previous scholars' values ​​is gender bias, especially in Q.S An Nisa': 34 regarding male leadership in the household, which is then responded by many Muslim leaders and even contemporary mufassir, one of them with the 'concept of gender harmony'. Therefore, this research will discuss how the application of the concept of gender equality to Q.S An Nisa': 34 and the response of Muslim leaders and commentators do they agree with 'gender equality', or are they against it? To answer this question, this research used a descriptive method. analysis related to the interpretation of Quraish Shihab who is a contemporary mufassir and critical thinker, thus in this study the results were obtained that in relations between men and women cannot be equalized as a whole as the concept of 'gender equality, because both have differences in nature which turn out to have been adjusted with their respective tasks such as discussing the concept of 'gender harmony'

Published: September 2023

O presente estudo tem como objetivo realizar uma revisão sistemática considerando as diversas fases do pensamento geográfico descritas na obra do geógrafo francês Georges Bertrand considerando, para isso, a sua contribuição na construção de uma “geografia física global”. Dentre as fases do pensamento de Bertrand, delimitamos quatro principais: (i) a difusão da geografia física global pautada no seu entendimento do conceito de paisagem como integrador à todas as áreas da geografia física; (ii) a análise da teoria do geossistema russo-soviético e sua reformulação pela tríade ‘Potencial Ecológico+Exploração Biológica+Ação Antrópica’ como elo de ‘uma nova’ geografia física global; (iii) a proposição de uma abordagem integrada do meio ambiente pelo modelo sistêmico tripolar GTP: Geossistema (fonte), Território (recurso) e Paisagem (ressurgimento); (iv) e, por último, o novo paradigma ambiental proposto pelo protocolo didático Sistema Paisagem Territorializada (SPT). Como metodologia, adotamos a pesquisa bibliográfica através de diversos artigos, livros e demais trabalhos acadêmicos que difundiram a obra de Bertrand na Europa e no Brasil tais como: Passos (2003 e 2016), Souza (2015), Reis Júnior (2007), Gonçalves (2016 e 2020). Esperamos contribuir para a discussão da teoria geossitêmica no território brasileiro, considerando o impacto da obra de Georges Bertrand no âmbito da geografia física e da abordagem da paisagem e geossitema no país.

Integrada no arquipélago dos Açores, a ilha das Flores, sob o ponto de vista do Geoparque, Património Geológico e Geomorfológico, tem uma paisagem de significativo valor cientifico, cujo atributos físicos constituem uma geodiversidade paisagística de significativa relevância, daí o objetivo em investigar a importância da paisagem nas 7 lagoas situadas no Platô Central. As lagoas Branca, Seca, Negra e Comprida ocupam a porção ao centro, mais a sul, ficam as lagoas Rasa e Funda, todas elas integradas em 2 dos 14 geossítios da Ilha das Flores. A leste nasce a Lagoa da Lomba que também complementa a rica biodiversidade. Para a investigação utilizou-se o método sistémico, análise integrada da paisagem, dos mapas temáticos, visitas “in Loco” e registos fotográficos. Os resultados indicam o papel preponderante das lagoas na representação da paisagem, contudo, é necessário maior empenho do poder público, juntamente com a sociedade, para um planeamento mais comprometido com a conservação.
O MODELO TEÓRICO DA PAISAGEM: UMA REVISÃO DE IDEIAS E ABORDAGENS
Authors: Glória Massoquim Nair , Oliveira-Costa Jorge Luis
Published: September 2023

A paisagem, antes de estabelecer-se como conceito, considerando desde que é vista como uma descrição de “tudo que a vista alcança”, acompanha a história da humanidade. Desvendar o meio, significava desvendar os seus traços, ou seja, compreender a paisagem. O presente trabalho tem como objetivo elaborar uma ‘revisão da paisagem’, considerando as ideias que surgiram desde o período em que a ‘paisagem’ ainda não constituía num conceito ou disciplina (tendo em vista que não possuía um método cientificamente estruturado), até as abordagens atuais. Assim, do ponto de vista metodológico, este trabalho constitui numa revisão sistemática sobre o tema da paisagem, considerando as diferentes abordagens que surgiram durante o período de consolidação do conceito: (i) a paisagem dos jardins históricos; (ii) a paisagem na arte das pinturas; (iii) a paisagem das viagens dos descobrimentos; (iv) a paisagem no estudo das plantas (botânica) e dos ecossistemas (ecologia); (v) a paisagem na visão da geografia (temporalidade/espacialidade de atributos físicos, humanos e culturais). Hoje a ‘paisagem’ é entendida como uma disciplina científica especializada, onde as novas áreas do conhecimento (que surgem no bojo das transformações da ciência moderna) vêm integrando e contribuindo com o modelo teórico da ‘ciência da paisagem’. O paisagismo, a arquitetura, o turismo, e a geografia contemporânea, por exemplo, que possuem tradição no uso e aplicação deste conceito, avançam atualmente no âmbito do modelo teórico da paisagem adotando-o como um importante aporte teórico-metodológico, sob uma abordagem multidisciplinar.

The residual stress state in meso- and micro-milling processes with a ball-end mill in Ti-6Al-4V titanium alloy
Authors: GARCIA-BARBOSA JORGE ANDRES , CORDOBA-NIETO ERNESTO
Published: September 2023

An experimental exploration research and comparison of the residual stress state between micro- and meso-milling processes with a ball-end mill on the Ti-6Al-4V titanium alloy were carried out. The residual stress state was analyzed based on the chip formation process according to the lead and tilt angles of the tool axis in relation to the normal vector to the surface. A novel idea was proposed to study the characteristic kinematics of a five-axis machining process, in a three-axis vertical machining center. When using the up-milling cutting strategy, it was found the defect of smeared/adhered material to the surface occurs in both the micro- and meso-milling levels, associated with the build-up edge and build-up layer phenomenon. The stress tensor of the surface was obtained using the X-ray diffraction technique. The down-milling cutting strategy produced the best surface finish and higher compressive residual stresses. Higher compressive residual stresses were found in the feed direction than in the cross-feed direction. The micro-milling process produced higher compressive residual stresses than those observed in the meso-milling process.

Published: September 2023

Background Nearly 60% of patients with cancer have metabolic syndrome, which increases the risk of mortality, but there is no clear guidance for oncology providers about its management. Here, we report on the qualitative component of a larger mixed methods study that aimed to understand cancer patients’ knowledge, attitudes, and preferences regarding metabolic syndrome. Methods Adult cancer patients with metabolic syndrome were recruited during 2022–2023 in the MD Anderson General Internal Medicine clinic and participated in semistructured interviews focused on metabolic syndrome and lifestyle interventions. Interviews were audio-recorded and transcribed verbatim. Participants’ demographic information was collected. Interviews were analyzed using hybrid thematic analysis and constant comparison involving deductive and inductive coding. Researcher triangulation and debriefing were used to ensure rigor. Results There were 19 participants, 12 female and 12 White. Eighteen had solid tumors, including gynecologic (n = 5), genitourinary (n = 4), colorectal (n = 3), and breast (n = 2). Analysis yielded 5 major themes: 1) patients’ understanding of metabolic syndrome; 2) attitudes about and approaches to managing metabolic syndrome; 3) capacity and limitations regarding managing metabolic syndrome; 4) patient-led care; and 5) tailored intervention plans. Participants had limited knowledge of metabolic syndrome and its cancer-related consequences; most desired additional education. Many participants reported that their cancer or diabetes diagnosis motivated them to prioritize lifestyle modifications. Participants expressed strong interest in personalized care plans focused on healthy lifestyle rather than simply weight loss. As part of their tailored intervention plans, participants desired clear communication with their medical team, coordination of care among team members, and collaboration with providers about treatment decisions. Conclusion Cancer patients with metabolic syndrome want collaborative, patient-centered care. Shared decision-making based on respect for patients’ distinctive needs and preferences is an essential component of the development of such collaborative care. Tailored interventions, practical implementation strategies, and personalized care plans are needed for cancer patients with metabolic syndrome. The study findings contribute to filling the gap in knowledge regarding clear guidance for oncology providers on managing metabolic syndrome and will inform the development of future lifestyle interventions for patients diagnosed with metabolic syndrome.

Published: September 2023

Deep eutectic solvent (DES) was prepared using choline chloride (ChCl), acrylamide (AM) and urea (U) as raw materials. CS and N-CNTs were added to DES as fillers, and composite hydrogels were prepared by in-situ polymerization (SP). The composite hydrogels were characterized and analyzed by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). In this paper, the pressure sensitivity, electrical conductivity, swelling and mechanical properties of the composite hydrogels were analyzed. The results showed that the pressure sensitivity of the composite hydrogels increased significantly after CS and N-CNTs were introduced into the hydrogels as fillers. When the filler content reached the highest, the pressure sensitivity of the composite hydrogels increased by 13 times compared with that of the hydrogels without filler. Due to the electrical conductivity of CS and N-CNTs, the higher the filler content, the stronger the electrical conductivity of the composite hydrogel, and the enhancement of electrical conductivity also has an impact on the pressure sensitivity of the composite hydrogel. This study provides a preparation method of composite hydrogel with excellent conductivity and pressure sensitivity.
Measurement of flow birefringence induced by the shear components along the optical axis using a parallel-plate-type rheometer

Published: September 2023

The present study investigated the flow birefringence induced by shear components along a camera's optical axis, which has been neglected in conventional theories of photoelastic measurements.
Measurements were conducted for a wide range of shear rates from a direction perpendicular to the shear using a high-speed polarization camera and a parallel-plate-type rheometer.
The measurement results obtained from a fluid with low viscoelasticity, specifically a dilute suspension of cellulose nanocrystals, showed that the birefringence increases monotonically as the stress components along the camera's optical axis increase.
It was also found that the birefringence showed a power law with respect to the shear rate.
This letter reports a key fact required for polarization measurements of shear rate (shear stress) in three-dimensional flows.
The relationship of electrical conductivity and percolation in composites of multiwall carbon nanotubes and thermoplastic polyurethane

Published: September 2023

The relationship of electrical conductivity and percolation has been characterised in detail for multiwall carbon nanotubes (MWCNT) in thermoplastic polyurethane (TPU). Weight fractions of MWCNT of up to 5 wt% were studied. Ultrasonic dispersion of the MWCNT during synthesis has been shown to significantly improve homogeneity and percolation of the composite material as evidenced by electron microscopy. Extending ultrasonication time improves the homogeneity of the composite material. The percolation threshold for homogenous MWCNT/TPU material has been determined as 0.95 wt%. Observing surface charging effects with electron microscopy is suggested as a method to probe mesoscopic uniformity. Material uniformity also relates to the magnitude of the apparent conductivity exponent, when conductivity data are fitted with the percolation law. The integration of MWCNT in the polyurethane matrix has been depth-profiled with electron microscopy by varying the energy of the primary electrons. This has shown that many MWCNT curl up into horseshoe shapes. The observation challenges the common assumptions that MWCNT retain their high aspect ratio in the composite material and that they can be modelled as straight rods.
Heavy Metal Transport With Adsorption for Instantaneous and Exponential Attenuation of Concentration
Authors: Liang Ruishi , Isa Zaiton Mat
Published: September 2023

Heavy metal pollutant is a serious problem in environmental pollutions, and it is very difficult to eradicate once the soil is contaminated with heavy metal. As heavy metal adsorption has been proven to occur, the heavy metal’s behavior can be modeled as a transport equation with adsorption. Based on two-dimensional model equations, analytical solutions are obtained for instantaneous and exponential attenuation of concentration injections boundary conditions, by utilizing the method of Laplace transform. The results highlight the significant influence of injection conditions on the peak concentrations. Furthermore, there exists a correlation between retardation factors and heavy metal concentrations, where a decrease in retardation factors leads to an increase in heavy metal concentration.

Published: September 2023

Geophysical inversion usually involves ill-posed problems. Regularization is the most commonly used method to mitigate the ill-posedness faced in geophysical inversions. Adaptive regularization methods have been more widely used in linearized inversion than in stochastic inversion methods. In this paper, we consider the contri-butions of the data fitting term and the stabilizing term in the objective function and give an improved adaptive regularization method for very fast simulated annealing (VFSA) inversion of transient electromagnetic (TEM) data. The optimized regularization method adjusts two terms dynamically in the objective function to make them in balance. In TEM inversion, we compare the results with that of the original SA and the widely used regularization techniques. For synthetic models where layered Earth is considered, we find the improved regularization can balance the data misfit functional and the stabilizing functional. We use arbitrary initial regularization values in the process. We also compare the computational efficiency and find the improved regularization method runs much faster due to the adaptive adjustment of the regularization. The inversion results are similar to that of the conventional ones. Finally, we apply this method to field data, and the inversion results show very good agreements with nearby borehole data.

Authors: Gbadebo Adegbuyi David , Akinwale Adio Taofiki , Sodiya Adesina Simon , Simeon A. Akinleye
Published: September 2023

The study presents an M/M/m queue model for a fuzzy-based management of parallel multiple servers. In this network, customers arrive according to a homogeneous Poisson process at rate λ and are served on first-come, first-served basis. The model may have up to three categories of servers viz: active servers, ’server(s) on vacation’ and reserved servers. In a situation where all active servers are busy and customers arrive, there are three possibilities: a server on vacation (if any), is turned on to attend to the arriving customers; the system request for additional server(s) from among reserved servers or the arriving customer(s) wait until one or more of the active servers becomes idle. Decision on management of servers is based on the output. This decision is taken by an Expert System which adopts fuzzy logic approach to process inputs as crisp variables to generate output based on given rules. This is necessary to ensure that available servers are put to optimal use while arriving customers are serviced within the shortest possible time and servers’ costs are minimized.
The physical significance of Hall and ion-slip effects on second-grade nanofluid flow over a vertically oriented surface with oscillating free-stream
Authors: Singh Jitendra Kumar , Maurya Ashish Kumar , Hussain Syed M.
Published: September 2023

This study is concerned with the simulations of impacts of Hall and ion-slip effects on the transient hydromagnetic convective flow of Titanium oxide-engine oil (TiO2-EO) second-grade nanofluid over a permeable vertically oriented surface. The flow considered originated due to the buoyancy action, rotatory fluid action and oscillatory free-stream motion. The tractable mathematical model of the fluid flow problem (flow governing equations) is obtained from field and constitutive equations under the boundary layer approximation. An analytical solution of the mathematical model is obtained with the aid of a perturbation solution scheme. Two physical cases of interest are considered, namely, the case of non-resonance and the case of resonance. The significance of impacting flow parameters to the flow is measured graphically by computation of solution in the non-resonance case. An important feature of the flow explored from the study is that both the Hall and ion-slip effects tend to stabilize the principal flow due to the revolution of ions and elections about a robust applied magnetic field. The Hall effect destabilizes the secondary flow. The consequence of the ion-slip current on the secondary velocity is opposite to that of the Hall current because of the heavier mass of ions in comparison to the electrons. When the time is very small, the principal velocity grows for the incremental values of oscillation frequency. This effect reverses as time progresses. The behaviour of the normal velocity for the oscillation frequency is exactly opposite to that of the principal velocity.

A Novel Hybrid EMPSO-PFTS Method for Fuzzy Time Series Forecasting: Integrating Picture Fuzzy Sets and Exponentially Mutated Particle Swarm Optimization
Authors: Dutta Debashis , Rath Subhabrata
Published: September 2023

Current research has demonstrated that fuzzy sets can be used to address forecasting issues. Researchers have created numerous fuzzy time series (FTS) approaches without taking into account the non-determinacy. For a considerable period, researchers have consistently focused on two significant key issues: determining the optimal interval size and incorporating non-determinacy. The focus of this article is to present a groundbreaking picture fuzzy time series (PFTS) forecasting model that is constructed based on the principles of picture fuzzy sets (PFSs). A PFS represents a generalized form of fuzzy and intuitionistic fuzzy sets. Here picture fuzzy clustering (PFC) technique is utilized for the construction of PFS. In this article, we integrate PFS and exponentially mutated particle swarm optimization (EMPSO) to develop a novel hybrid EMPSO-PFTS forecasting method. Optimal length is determined by EMPSO, and non-determinacy is taken into account by PFS when time series data is fuzzy. The suggested forecasting method is used on data sets from the University of Alabama and the market price of the State Bank of India (SBI-P) at the Bombay Stock Exchange, India, to demonstrate its applicability and usefulness. Mean square error (MSE) and average forecasting error (AFE) are used to gauge the effectiveness of the proposed method. The significant reduction in both MSE and AFE is strong evidence of the superior performance of the proposed EMPSO-PFTS method compared to various existing methods. To ensure the reliability and validity of the proposed method, rigorous statistical validation and performance analysis are conducted.

Published: September 2023

The immersive development in computing and communication systems, especially the evaluation of multimedia technology, has created various new paradigms. One of the concepts that has popped up recently is the metaverse. The technology opens different environments to the users for rapid connection on any of the socio-cyber platforms. With the emergence of 3D virtual gaming and its association, this technology has become one of the hot research areas, whether the work on headsets or the quality of experience (QoE) while using recent headset models by users and assessment. In multimedia systems, gaming is the only domain that is successfully involved among users, which generates millions of dollars in revenue in a single day. However, the collaboration of the metaverse in the gaming industry takes the user experience to the next level in terms of being completely disconnected from the real-world scenario, which means a fully immersive virtual environment. It includes the concept of lightweight visualization, a place with free headset activities, and a moving, immersive 3D multimedia experience. Although these are the advantages of the collaborative approach, various QoE challenges, standard requirements, and media consumption problems have emerged. By analyzing these prospects, this paper contributes to two subdomains. First, a novel framework for securely connecting metaverse technology in multimedia gaming is proposed. While using conventional metaverse technology, the role of QoE is addressed in the general-purpose gaming environment deployment. Second, this paper presents a gamer-oriented experience and assessments for the betterment of technological maturity and future developments. In addition, this paper mentioned a possible solution to the list of comprehensive standard requirements and related challenges.

Variation of the feeding/resting period in modified vertical treatment wetlands (depth, zeolite as medium) employed for treating rural domestic wastewater in tourist areas
Authors: Vera-Puerto Ismael , Valdés Hugo , Correa Christian , Olave Jorge , Pérez Valeria , Arias Carlos A.
Published: September 2023

This work aimed to evaluate the performance of modified vertical flow treatment wetlands (VF-TWs) in terms of depth and medium to assess the effect of the feeding/resting periods and footprint (FP). The modifications were proposed for treating domestic wastewater in rural areas with flow variations such as tourist sites. The experimental setup included six laboratory-scale VF-TWs: (a) normal (VF-N), bed depth 1.0 m, filled with sand and (b) modified (VF-M), bed depth 0.5 m, filled with sand (upper) and zeolite (bottom, saturated). The operation was divided into three phases (3 months each), varying the feeding/resting period and FP: phase I, 5 d/10 d, 2.6 m2/person-equivalent (PE); phase II, 3.5 d/3.5 d, 1.7 m2/PE; and phase III, only feeding no resting, 0.85 m2/PE. Influent and effluent grab samples were taken every 2 weeks. The results showed effective removal (above 60%) of total solids, organic matter, and pathogens for both VF-N and VF-M. Regarding nutrients, VF-M showed a phosphate removal below 60%, but no consistent removal (15–60%) of total nitrogen. Thus, the results suggest that proposed modifications can be an option to be established in tourist sites, but further work should be conducted to improve and optimize total nitrogen removal.
KAMIENIE MILOWE W KARIERZE ZAWODOWEJ – RAPORT Z BADAŃ DOJRZAŁYCH NAUCZYCIELEK
Authors: Strutyńska-Laskus Elżbieta
Published: September 2023

W artykule podejmuję wątek znaczenia kamieni milowych w przebiegu karier widziany z perspektywy nauczycieli z długim stażem pracy. Przez kamienie milowe rozumiem emocjonalnie znaczące punkty zwrotne związane z jakimś szczególnie ważnym dla nauczyciela wydarzeniem wyraźnie oddzielające jedną fazę kariery od kolejnej. Te znaczące wydarzenia prowadzą do zmian w podejściu do wykonywania pracy zawodowej nauczyciela.

Podstawą zaprezentowanych analiz jest 14 indywidualnych wywiadów pogłębionych (IDI) z nauczycielkami, które mają wieloletni staż pracy w szkole (minimum 20 lat) i ukończony 50 rok życia. W badaniach zastosowałam analizę tematyczną, której celem jest identyfikacja powtarzających się wątków tematycznych w wypowiedziach nauczycielek, a dotyczących znaczących emocjonalnie punktów zwrotnych, których skutki dla przebiegu karier mogą być korzystne (pozytywne) i/lub niekorzystne (negatywne). Dane kodowałam w ramach podejścia indukcyjnego. Jakościową analizę danych przeprowadziłam z wykorzystaniem programu MAXQDA 2020.

Na podstawie treści zgromadzonego materiału wyłoniłam dwie kategorie wątków tematycznych prowadzących do zmian w funkcjonowaniu zawodowym nauczycielek biorących udział w badaniu. Pierwsza z nich wskazuje na rolę wydarzeń znaczących emocjonalnie niezaplanowanych i niezależnych od nauczyciela, które są następstwem okoliczności zewnętrznych obiektywnych lub subiektywnych. Druga – dotyczy wydarzeń/działań znaczących emocjonalnie zaplanowanych i zależnych od nauczyciela, które są związane z czynnikami wewnętrznymi.

Z badań wyłania się obraz „pozytywnych” i „negatywnych” kamieni milowych mających znaczenie dla funkcjonowania w roli nauczyciela. Znajomość szczególnie tych drugich może przyczynić się do przeciwdziałania negatywnym emocjom towarzyszącym codziennej pracy nauczyciela, w tym wypaleniu zawodowemu.

been reported to possess a neuroprotective role by decreasing oxidative stress-induced neuronal
cell damage. The use of QC for neurodegenerative therapy, the existence of the blood–brain barrier
(BBB) remains a significant barrier to improving the clinical effectiveness of the drug, so finding
an innovative solution to develop simultaneous BBB-crossing ability of drugs for treating neurodegenerative
disorders and improving neurological outcomes is crucial. The nanoparticle formulation
of QC is considered beneficial and useful for its delivery through this route for the treatment
of neurodegenerative diseases seems necessary. Increased QC accumulation in the brain tissue and
more significant improvements in tissue and cellular levels are among the benefits of QC-involved
nanostructures.

Este número de Tiempo & Economía inicia con una sección especial titulada La marca de la Misión Kemmerer en la historia económica de Colombia en la que se presentan dos artículos que dan cuenta del impacto de la Misión en el desempeño económico e institucional de los países a los que llegó, con lo que la revista conmemora los 100 años de la primera Misión Kemmerer en Colombia. Los primeros 100 años de experiencia republicana en Colombia dejaron un sistema económico rezagado con respecto a otros países con historias similares en la región; este retraso se evidenciaba tanto en sus estructuras productivas como en sus instituciones. El año 1923 marcaría una profunda transformación de las instituciones económicas y fiscales con la Misión Kemmerer: la fundación del Banco de la República, la Contraloría General de la República y la Superintendencia Bancaria redefinió las principales reglas del juego de la economía.
Regionalização e Descentralização em Portugal: Reforma do Estado, Aprofundamento da Democracia e Desenvolvimento
Authors: Ribeiro J. Cadima
Published: September 2023

O debate da Regionalização de Portugal voltou a emergir. Periodicamente, tem-se retomado a discussão do tema, se bem que sem consequências de maior. A exceção em matéria de alcance do debate que foi acontecendo foi a realização do referendo de 8 de novembro de 1998, cujo resultado significou a criação de um bloqueio substantivo à institucionalização da instância regional de governo. Por detrás desse retomar do debate estão, por um lado, a inclusão dessa temática no Programa do XXIII Governo, definindo-se aí o objetivo de realizar um novo referendo em 2024, e, por outro lado, as sequelas da implementação da Lei nº 50/2018, de 16 de agosto, que estabeleceu a transferência, gradual, de um conjunto alargado de competências para as “autarquias locais” e as “entidades intermunicipais”. Tendo presente o contexto que se enuncia, importa refletir sobre a oportunidade e os fundamentos para se avançar no processo de regionalização em Portugal, e sobre aquilo que pode estar em causa quando se encetam iniciativas de descentralização do poder suportadas apenas nas instâncias locais. Obviamente, equacionando-se a regionalização, volta a ser necessário discutir as potenciais soluções de divisão territorial e os seus fundamentos económicos, sociais, culturais e políticos, e a escolha das próprias cidades-capital. São essas problemáticas e este debate que este livro coletivo se propõe retomar, reclamando para tanto o contributo de um conjunto de académicos de várias formações científicas e sensibilidades político-sociais. Os destinatários da publicação são, também, os académicos, mas, igualmente, os decisores públicos e todos aqueles que, comprometidos com o desenvolvimento do país, olham para a reforma da sua organização político-administrativa como a grande reforma estrutural de que Portugal realmente carece.
11. Fronteiras de paz e desenvolvimento
Authors: Dentinho Tomaz Ponce
Published: September 2023

A Ciência Regional não explica fronteiras políticas e prefere falar de centros e periferias, sendo que estas são normalmente zonas de fronteira. Deixa assim para as ciências históricas, para a ciência política e para as ciências da guerra a explicação da fronteira, condicionadas pela geografia física e pelo poder do mais forte. O objetivo deste texto é perceber a fronteira do ponto de vista da ciência regional que estuda a interação das pessoas e dos sítios no território. Para isso propõe-se um modelo de análise das fronteiras com quatro tipologias: duas fronteiras estáveis de mercados terrestres e de mercados marítimos; e duas fronteiras instáveis de afetação igualitária de bens públicos e de fronteiras de afetação de rendas dos recursos naturais. Justifica a instabilidade das fronteiras e foca-se no desenho das fronteiras entre países marítimos, que visam garantir a segurança da costa em torno de dois portos, e terrestres, que visam a segurança de portelas terrestres e de algum acesso ao mar. A aplicação do modelo de análise a Portugal, Ucrânia, Brasil e Albânia serve para comprovar a generalidade do modelo que, ajustado à escala regional, implica a criação de regiões de montante e de jusante.
2. O estado do Estado: a regionalização no quadro da Constituição Portuguesa e da abertura à União Europeia
Authors: Rocha Joaquim Freitas da , Barbosa Andreia
Published: September 2023

Se já se havia constatado que o Estado unitário, na sua conceção mais pura, se havia tornado demasiado pequeno para responder à sociedade aberta, europeia e internacional, o reavivar do debate em torno da descentralização permite constatar, agora a um outro nível, que tal Estado é, simultaneamente, demasiado grande para fazer face a necessidades territorial e particularmente localizadas. A questão que se tem vindo a levantar a propósito é a de saber qual é a intensidade ou a extensão que deve assumir a repartição ou o descongestionamento de poderes entre diferentes entidades públicas. Em particular, discute-se se a descentralização deve refletir-se na criação, em Portugal continental, de Regiões administrativas.

This research aims to scrutinize the impact of multiple intelligences-based differential learning on the enhancement of critical thinking skills among university students. A cohort of sixty-six teacher students actively participated in this empirical investigation. Critical thinking proficiency was meticulously assessed employing a battery of tests and a comprehensive questionnaire. The findings of this study unequivocally demonstrate that multiple intelligences-based differential learning exerts a discernible influence on the development of critical thinking abilities among university students. Intriguingly, the study found no significant difference in critical thinking performance among the various types of intelligence. Additionally, this research posits that differential learning grounded in multiple intelligences represents a viable alternative pedagogical approach that should be earnestly embraced by educators when devising and implementing instructional strategies and methodologies. Such an approach, the study contends, holds the potential to augment students' cognitive capacities in a manner that aligns with the exigencies of 21st-century education.
A Rare and Complex Case of Multifactorial Thrombotic Microangiopathy in A Kidney Transplant Recipient: Interplay Between Antibody Mediated Rejection, Tacrolimus Toxicity, Cytomegalovirus Disease and BNT162b2mRNA Vaccine

Published: September 2023

Thrombotic microangiopathy (TMA) in kidney transplant recipients is uncommon and difficult to manage, often with poor graft outcomes [1]. This is a complex and interesting case of an older, highly sensitised kidney transplant recipient who presented with de novo post-transplant TMA in the setting of antibody mediated rejection (ABMR), with other drivers being tacrolimus toxicity, cytomegalovirus (CMV) infection and anti-SARS-CoV-2 BNT162b2 mRNA vaccination. This led to rapid, irrecoverable graft loss. 76-year-old female presenting three years post deceased donor renal transplant with ABMR. Her three-year course post-transplant was complicated with further opportunities for sensitisation. Firstly, with two discrete episodes of CMV disease requiring alteration in immunosuppression regimen. Secondly, she had a biopsy-confirmed episode of cell mediated rejection after switching from tacrolimus to everolimus due to tacrolimus toxicity. Finally, her admission with fulminant rejection was preceded by almost 6 months of sub-therapeutic tacrolimus levels. 4 weeks prior to this admission, the patient also had her second dose of BNT162b2 mRNA vaccine. Her graft function deteriorated rapidly, with final transplant biopsy showing severe TMA with graft infarct. This case illustrates a complex case of a highly sensitised patient with a difficult post-transplant course who unfortunately suffered a very severe episode of ABMR-associated TMA after further sensitisation during her post-transplant course, with other drivers including CNI toxicity and CMV disease as well as potential further immune stimulation from BNT162b2 mRNA vaccine.

BACKGROUND

Teledentistry refers to the use of telehealth systems and methods for remote dental examination, diagnosis, consultation, and treatment planning. Dental mobile applications can promote public dental health. Due to the fact that the attitudes of parents influence their young children, we investigated 3 hypotheses: 1) Parental attitudes regarding the use of dental apps will be positive for themselves and their children; 2) The attitude of the parent will be more positive for dental apps for their children than for themselves; 3) Parents with higher usage of medical apps, will have more positive attitudes to using dental apps and be more willing to pay for the service.

OBJECTIVE

The aim of this study was to examine the attitudes of parents of kindergarten children regarding the use of applications that encourage the promotion of oral health.

METHODS

This cross-sectional questionnaire-based study examined the attitude of parents regarding the use of dental apps. The anonymous questionnaire was distributed through social media in WhatsApp groups of parents with children aged 0-6 years in Israeli kindergartens and schools.

RESULTS

The more apps a person uses in their daily life, the more medical and dental apps they utilize. Higher usage of dental apps improved attitudes towards these applications in the parent group (p<0.01). Positive attitudes increased willingness to pay for the applications (r=.148, p<.001).

CONCLUSIONS

Health apps change interactions with health care professionals, enabling remote access with doctors and dentists. Parents of young children had positive perceptions of the usefulness of applications as a tool to promote the oral health of their children.
