Hematite nanostructures are strong candidates for the development of sustainable water splitting technologies. However, major challenges exist on improving charge density and minimizing charge recombination rates for a competitive photoelectrochemical performance based on hematite without compromising sustainability aspects. Here we develop a synthetic strategy to leverage earth-abundant Al3+ and Zr4+ in a dual-chemical modification to synergistically minimize small polaron effects and interfacial charge recombination. The solution-based method simultaneously induces Al3+ to dope the hematite crystal lattice while Zr4+ forms interfacial excess, creating a single-phased homogenous nanostructured thin film. The engineered photoanode increased photocurrent from 0.7 mA cm− 2 for pristine hematite up to 4.5 mA cm− 2 at 1.23V and beyond 6.0 mA cm− 2 when applying an overpotential of 300mV under simulated sunlight illumination (100 mW cm− 2). The results demonstrate the potential of dual-modification design using solution-based processes to enable sustainable energy technologies.

Purpose
The Centiloid (CL) scale is a standardized measure for quantifying amyloid deposition in amyloid positron emission tomography (PET) imaging. We aimed to assess the agreement among three CL calculation methods: CapAIBL, VIZCalc, and Amyquant.
Methods
This study included 192 participants (mean age: 71.5 years, range: 50–87 years), comprising 55 with Alzheimer's disease, 65 with mild cognitive impairment, 13 with non-Alzheimer's dementia, and 59 cognitively normal participants. All the participants were assessed using the three CL calculation methods. Spearman's rank correlation, linear regression, Friedman tests, Wilcoxon signed-rank tests, and Bland–Altman analysis were employed to assess data correlations, linear associations, method differences, and systematic bias, respectively.
Results
Strong correlations (rho = 0.99, p < .001) were observed among the CL values calculated using the three methods. Scatter plots and regression lines visually confirmed these strong correlations and met the validation criteria. Despite the robust correlations, a significant difference in CL value between CapAIBL and Amyquant was observed (36.1 ± 39.7 vs. 34.9 ± 39.4; p < .001). In contrast, no significant differences were found between CapAIBL and VIZCalc or between VIZCalc and Amyquant. The Bland–Altman analysis showed no observable systematic bias between the methods.
Conclusion
The study demonstrated strong agreement among the three methods for calculating CL values. Despite minor variations in the absolute values of the Centiloid scores obtained using these methods, the overall agreement suggests that they are interchangeable.

Published: November 2023

In this work, the Poly (methyl methacrylate) (PMMA) films have been developed for the photodegradation of methylene blue (MB) by incorporating vanadium pentaoxide (V2O5) catalysts. The obtained films were characterized by SEM, XRD, UV-Vis, FTIR and Raman spectroscopy. The XRD patterns revealed the amorphous domains of the PMMA polymer, with an increase in these domains with increasing the V2O5 content. Moreover, the XRD showed shifts of 2θ from 16.55° to 17.8°, which can be attributed to the structural irregularity of the PMMA backbone chain caused by the nanofiller doping with no impurity peaks. The observed SEM images showed that V2O5 has a hierarchical nanobelt interconnected structure with thicknesses of 30–150 nm and 50–300 nm in length. According to UV-Vis spectroscopy measurements, the absorbance shifts towards a longer wavelength (270–330 nm) and exhibits intensity increase as V2O5 nanoparticles amount increase. The band gap of PMMA was decreased after the incorporation of V2O5 NPs. The optical conductivity σop exhibits an increase in the photon energy window (3.8 eV-4.2 eV) by values (2x1011 – 7x1011) as the V2O5 nanoparticles ratio content increases. Interestingly, the 3.3 wt% V2O5/PMMA photocatalyst film exhibited the highest photocatalytic degradation of MB (97%) after 45 minutes of UV illumination.
Assessing wetlands ecological risk through an adaptive cycle framework
Authors: Zhu ying , Jin wenwen
Published: November 2023

Contexts.
Wetlands in areas of rapid economic development are at increased risk, which leading to significant losses to wetlands over time. Thus, it is urgent to declare and assess multi-ecological risk.
Objectives.
Wetland ecosystems are characteristics of adaptive. This study assesses wetlands ecological risk through adaptive cycle theory which are beneficial to highlight system dynamic. The study aims to reflect the response relationship between multiple risk sources and wetland ecosystems and predict future dynamic development phase.
Methods.
The study uses Kunshan wetlands of China as an example for constructing a wetland adaptive cycle framework firstly, determining indicators in 3-D dimensions of “Potential-Connectedness-Resilience,” and proposing a wetland ecological risk assessment system.
Results.
The results show that the spatial distribution of the ecological risk of "Potential" is highest in the Kunshan urban central region and lowest in the Kunshan north area, which is closely related to climate change. The ecological risk of whole area of “Connectedness” is high, and human activities have a greater impact on it. The resilience of wetlands needs to be continuously improved, and wetland ecosystem services need to be balanced. Regarding the adaptive cycle phases of ecological risk, Kunshan wetlands are in the exploitation r-phase and will transition to the conservation K-phase in the future.
Conclusions.
This study offers a logical reference for understanding the ecosystem dynamic development and analyzing ecological risks. Furthermore, it provides a direction for sustainable wetlands ecological protection strategies in areas with rapid economic development in global developing countries.
The psychology of Mona Lisa’s expression
Authors: Soranzo Alessandro
Published: November 2023

The Mona Lisa's ambiguous expression has captivated viewers for centuries, prompting diverse explanations. This article proposes a novel interpretation grounded in the psychological theory of perceptual organisation. Central to the investigation is the “Ambiguity Smudge”, a dark region above the mouth, hypothesised to influence perceived expression due to perceptual organization. Through carefully crafted artwork and systematic manipulations of Mona Lisa reproductions, experiments reveal how alterations of the Ambiguity Smudge generate distinct expressions. Specifically, the manipulation of the perceptual relationships between the Ambiguity Smudge and the mouth yields significant shifts in perceived expression. These findings not only underscore the pivotal role of psychological principles in shaping ambiguous expressions in the Mona Lisa, but also extend to other Leonardo’s portraits, namely La Bella Principessa and Scapigliata. This study sheds light on the intersection of psychology and art, offering new perspectives on timeless masterpieces.

Published: November 2023

Context and purpose
Research reviews the findings, course of therapy, and outcomes of gastric metastases (GM). With this investigation, we hope to contribute to the increasing amount of information by providing practitioners with a reliable and practical platform for understanding stomach metastases from various primary malignancies.
Methods: This study covered papers published in English from the MEDLINE and Cochrane databases until May 2022. The deleted materials included editorial emails, billboards, surgical photos, and non-English publications. Hematogenous and lymphogenic metastases were noted, yet primary tumor progression and dissemination were not. Using pre-established criteria for eligibility, the ultimate selection was made after the articles and abstracts were reviewed and cross-referenced.
Results: A total of 186 GM cases were listed in 1,521 papers that were eventually found. The average of sixty-two years. The majority of GM cases (67) were attributed to reproductive cancers, with lung tumors (33 patients), carcinoma of the kidney (20 patients), and melanomas (19 patients) trailing closely behind. The main treatment strategy for metastases is excision surgery (n = 62), often in combination with immunotherapy or chemotherapy (ChT). Among the 78 therapeutic options, ChT was the second-most preferred choice. Furthermore, immunotherapy was one of the most preferred treatment alternatives (n = 10) following surgery and ChT.
Conclusions: Heterogeneity was inevitable because 172 case reports from different journals were included in this systematic review. Certain papers have omitted crucial facts such as comprehensive monitoring and scientific information. Additionally, since every article featured was a personal study, it was not possible to evaluate the quality of the work. In the majority of the 172 cases that were examined, resected procedures occurred; on rare occasions, immunotherapy and ChT were also combined. The best course of action for patients with stomach metastases requires further investigation.
A deep learning approach with weighted voting for Moroccan sign classification
Authors: CHERRATE meryem , SABRI My Abdelouahed , Ali YAHYAOUY , Abdellah AARAB
Published: November 2023

In our Moroccan society, as in the rest of the world, we find a significant proportion of deaf-mutes who represent 5% of the world's population, the equivalent of 466 people suffering from hearing loss. These people use sign language as a means of transmitting their messages, emotions and expressions to other people, which implies little or no hearing. To facilitate communication between deaf-mutes and normal people who do not know sign language, we have proposed in this article an approach that enables the textual transcription of sign language into natural language. Due to the development of Artificial Intelligence, we will propose an approach that is based on a combination of four deep learning architectures, with the weights of each architecture calculated according to their performance using genetic algorithms. It turns out that using the weighted voting method of deep learning or the so-called ensemble method gives a better performance to the results obtained using each deep learning architecture separately and compared to recent approaches in the literature, enabling us to predict signs and improve the accuracy rate to 99%.
The Fuel Cycle of the Future: Water to Fuel to Water
Authors: Proca Adrian C
Published: November 2023

Background: Fuel cells are a clean, renewable source of energy that may become the fuel of the future, next to solar, wind, geothermal energy.
Problem: There are many technological hurdles that must be fixed before hydrogen fuel cells replace pollutants like coal and oil. Hydrogen fuel cells are inefficient, and the process of creating hydrogen uses a lot of energy, so the problem tackled in this project is to optimize efficiency of hydrogen generation from electrolysis.
Hypothesis: We hypothesize that: 1. An increase in water temperature will increase efficiency 2. An increase in current through the cell will increase efficiency 3. The use of catalyst will increase efficiency.
Materials and Procedure: Using alligator clips a circuit was built, consisting of breadboard, power supply, voltmeter, and resistors. An electrolysis bath was created as described in detail in the paper. The data was collected in two sets: with and without catalyst (cobalt nitrate). For each set, the water temperature was increased to 75 degrees Celsius and was let to cool naturally to 22 degrees Celsius. Electrolysis was performed during cooling, using a current of approximately 3 mA.
Results: Every two degrees (C): the cell voltage was measured; the current was decreased to 2 mA and then to 1 mA and measurements were taken for those two currents as well, resulting in 3 cell voltage measurements for each temperature point; the current was then returned to 3 mA. The efficiency of reaction was calculated at start, baseline and after adding progressively more catalyst.
Conclusion: Hypothesis 1, the temperature dependency, was correct. Hypothesis 2 was the exact opposite of what we expected: the efficiency increased with a decrease in cell current. However, it is possible that in spite of having a better energy efficiency, the hydrogen output could have also been reduced. Hypothesis 3, the role of the catalyst, was also proven to have a substantial effect, especially at lower temperature and high current.

Authors: Mogaraju Jagadish Kumar
Published: November 2023

We attempted to show the effect of lockdown on the aerosol, black carbon, dust, and organic carbon loads and their influence on moderating surface temperatures. This study produced and interpreted Time-averaged maps for three phases, i.e., pre-lockdown, lockdown, and post-lockdown phases. We observed a 4% increase in black carbon loads during the lockdown period compared to pre-lockdown and a 27% increase in the post-lockdown period. It was observed that there was a 6% increase in dust loads during the lockdown period and a 5% increase in the post-lockdown period when compared with pre-lockdown levels. Approximately a 48% increase in organic carbon loads during the lockdown period and a 24% increase in the post-lockdown period was observed. We observed a 12% increase in surface temperatures during the lockdown period and almost no considerable increase in the post-lockdown period.

A citation analysis examining geographical specificity in article titles
Authors: Burns C. Sean , Islam Md. Anwarul
Published: November 2023

This investigation explores the impact of geographical names within article titles on citation frequency across a corpus of literature within the field of library and information science, spanning from 2018 to 2020, and encompassing sixty-one journal titles. We hypothesized that the presence of geographical names of nations in article titles would negatively correlate with citation frequency. Our primary analysis of 1484 articles with geographical names versus 11652 without, revealed a statistically significant, albeit small, difference in median citations, favoring articles without geographical names (mdn = 7) over those with geographical names (mdn = 6). Contrary to our secondary hypothesis, a proximity analysis demonstrated a weak, positive correlation between the closeness of geographical names to the title end and citation counts. Additionally, our examination found no evidence supporting differential citation frequency based on the Human Development Index (HDI) of the nations mentioned in titles, nor did the impact factor of the journal moderate the relationship between geographical names and citation frequency. A weak, negative correlation was discovered between the frequency of geographical names in journal titles and the journals’ impact scores, yet this was not statistically significant. Our data also suggested a vague positional preference for nations within titles, unrelated to HDI. Furthermore, the likelihood of journals publishing articles mentioning nations of varying HDI was found to be statistically insignificant. This study sheds light on the nuanced influence of title specificity, through geographical names, on scholarly communication and citation impact, indicating a slight preference for broader title phrasing in garnering citations.
Der Einfluss von Trauma-aktiviertem platelet-rich fibrin auf mesenchymale Stammzellen in vitro
Authors:   , Bohl Isabell
Published: November 2023

Ziel dieser Arbeit war es, die Wechselwirkung zwischen MSC und PRF von Traumapatienten herauszuarbeiten und zu überprüfen, ob ein therapeutischer Einsatz der Kombination von MSC und Trauma-aktiviertem PRF in Frakturen sinnvoll erscheint. Hierfür wurden MSC mit PRF über einen Zeitraum von 24 oder 120 Stunden co-inkubiert und die metabolische Aktivität, definierte Faktoren im Überstand (IL-6, CXCL10, VEGF und IDO-2) und die Genexpression ausgewählter Faktoren (MAPK8, MAPK14, IL-6, CXCL10,IDO-1, TNFAIP6, VEGFA, RUNX2 und COL1A) in bis zu drei Messzeitpunkten überprüft. Die Versuche erfolgten vergleichend mit Traumapatienten und gesunden Probanden. Es konnte gezeigt werden, dass Trauma-aktiviertes PRF verglichen mit PRF von gesunden Probanden die metabolische Aktivität von MSC nach 120 Stunden erhöhen kann. Zudem stellten sich erhöhte Werte des inflammatorischen Faktors IL-6 im Überstand bei Traumapatienten nach 24 und 72 Stunden dar, welche bis zum dritten Messzeitpunkt nach 120 Stunden wieder abfielen. Ein ähnlicher Verlauf zeigte sich bei den Messwerten von VEGFA, einem Faktor, welcher eine große Rolle bei der Angiogenese spielt. Über alle Messzeitpunkte hinweg konnten niedrigere Werte in der Genexpression von COL1A und RUNX2 im Vergleich zu den Kontrollmessungen erfasst werden. Die Ergebnisse zeigen, dass im Vergleich zu PRF gesunder Probanden Trauma-aktiviertes PRF die Möglichkeit besitzt, die Proliferation von MSC zu stimulieren. Außerdem wurde beobachtet, dass Trauma-aktiviertes PRF ein inflammatorisches und angiogenetisches Potenzial nach 72 Stunden besitzt, welches nach 120 Stunden allerdings wieder abfällt. Möglicherweise kann durch den Einfluss von MSC der Inflammation entgegengewirkt werden. Ein signifikantes osteogenes Potenzial des Trauma-aktivierten PRFs konnte zu keinem Messzeitpunkt nachgewiesen werden. Inwiefern der Einsatz von MSC in Kombination mit Trauma-aktiviertem PRF die Frakturheilung verbessern kann, konnte in der vorliegenden Studie nicht eindeutig geklärt werden. Es kann allerdings davon ausgegangen werden, dass die Implantation von Trauma-aktiviertem PRF und MSC in den Defekt erst nach Verstreichen einer bestimmten Zeitperiode nach dem Trauma durchgeführt werden sollte. Die Gründe für diese Annahme sind das erhöhte proliferative und verringerte inflammatorische Potenzial im Verlauf. Eine Ursache für das Fehlen der osteogenen Differenzierung der MSC kann der kurze Messzeitraum sein. Weitere Studien sollten folgen, um das Potenzial der Kombination von MSC und Trauma-aktiviertem PRF als therapeutisches Verfahren zu überprüfen.

Published: November 2023

Este trabalho apresenta resultados de uma pesquisa empreendida com o objetivo de analisar como as práticas educativas realizadas em uma Escola Família Agrícola (EFA) localizada na zona rural de Teresina – PI, fundamentadas em pressupostos da Pedagogia da Alternância, se articulam com os princípios da Educação do Campo, diante do processo de estadualização da instituição. Para tal, realizou-se uma pesquisa descritiva, de natureza qualitativa, cujos procedimentos de produção de dados foram: análise documental, entrevista semiestruturada e aplicação de questionário. A partir da análise dos dados, constatou-se que a EFA pesquisada utiliza algumas ferramentas da Pedagogia da Alternância, facilitadoras do ensino-aprendizagem; no entanto, é visível que o processo de estadualização fragilizou a realização das atividades educativas. Os resultados também evidenciaram a empatia dos discentes quanto às metodologias utilizadas por seus professores. Concluiu-se que, apesar das dificuldades, há mais proximidades que afastamentos entre os princípios da Pedagogia da Alternância desenvolvida pela EFA e os que regem a Educação do Campo.

Authors: Caldeira Bianca
Published: November 2023

Este estudo teve como objetivo analisar a percepção de alunos, professores e gestores acerca das práticas de ensino adotadas no Ensino Superior, e suas implicações no processo de ensino-aprendizagem dos estudantes em Engenharia. Participaram nesta investigação 208 professores, 460 alunos e 9 gestores de uma universidade brasileira. O design de investigação assentou numa abordagem mista, combinando diferentes tipos de métodos de natureza quantitativa e qualitativa, utilizando diferentes técnicas de recolha de dados.  Os resultados sugerem que muitos docentes e gestores ingressaram de forma circunstancial e que suas práticas de ensino se centram nas suas experiências enquanto alunos. Já os alunos apontam para uma necessidade de mudança nas práticas didáticas e pedagógicas dos docentes, uma vez que o perfil dos alunos sempre muda. Os dados sugerem que alguns professores buscam inovar suas metodologias, no entanto, os professores têm encontrado desafios como: o número excessivo de alunos por turma; falta de espaços diversificados de aprendizagem; falta de conhecimento de técnicas de ensino-aprendizagem e de avaliação assim como de metodologias ativas de aprendizagem; e a falta de recurso financeiros. Por fim, os participantes da universidade brasileira apontam para a necessidade de capacitação futura no âmbito didático-pedagógico para que possam adequar suas práticas de ensino.
Uma década de desinvestimento em educação pública superior: Um estudo sobre o financiamento da UFPel entre 2010 e 2020
Authors: Dutra Geovanna Caroline Zanini , Frizzo Giovanni
Published: November 2023

Este estudo tem por objetivo apresentar os cenários das políticas de financiamento da educação pública superior nos anos de 2010 e 2020 e estabelecer uma relação comparativa com os investimentos do poder público na Universidade Federal de Pelotas (UFPel) nos anos de 2010 e 2020. Para tal, analisa artigos científicos produzidos por pesquisadores da área sobre este período e confronta-os com os Relatórios de Gestão da UFPel utilizando a metodologia de análise de documentos. Parte do conceito de crise estrutural para compreender a saída para a crise por via do neoliberalismo, que também afeta as instituições de ensino, em especial as públicas, que tem seus recursos acaçapados devido à reorganização financeira que os governos praticam para a contenção de gastos em serviços públicos. Ao final, o artigo conclui que há uma defasagem de recursos financeiros para as universidades públicas, ao mesmo tempo que há fomento à rede privada de ensino superior, que cresce mais em relação às IFES. Conclui também que apesar do crescimento do número de IFES em 10 anos, ele não é linear, pois o corpo discente, docente e técnico-administrativo diminuiu na UFPel.

Authors: De Oliveira Marcos Antonio , Souza Francisco das Chagas Silva , De Oliveira Veroneide Maria
Published: November 2023

A expansão e interiorização da Educação Profissional e Tecnológica (EPT), nas primeiras décadas deste século, levou o Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN) a ampliar de 2 para 22 o seu número de campi distribuídos em todas as microrregiões do Estado. Nosso objetivo, neste trabalho, é discutir a nova espacialização dos campi do IFRN e analisar os impactos trazidos por essa política de interiorização do ensino profissional em vários níveis, desde os de formação inicial ao superior e pós-graduação. Trata-se de uma pesquisa de caráter qualitativo, com análise de documentos institucionais, tais como: o Projeto Político-Pedagógico, o Plano de Desenvolvimento Institucional e os Relatórios de Gestão. Também foram usados depoimentos de alunos contemplados pela política de expansão, cujos relatos se encontram no Portal do IFRN. A pesquisa revelou a relevância da política de expansão da EPT para a democratização e inclusão social no Rio Grande do Norte, ao permitir a realização de projetos pessoais que dificilmente seriam alcançados sem a instalação de um campus do IFRN.

Authors: Padros-Blazquez Ferran , Reynoso González Oscar Ulises , Martínez-Medina María Patricia
Published: November 2023

La escala de Afecto Positivo y Negativo para niños y adolescentes (PANAS-N) es uno de los instrumentos más utilizados para la investigación en el ámbito de la psicología básica, positiva y clínica. El objetivo del presente trabajo fue estudiar las propiedades psicométricas, ofrecer datos descriptivos (media, desviación estándar y percentiles) e identificar posibles diferencias en las puntuaciones del PANAS-N, de acuerdo con el sexo y la edad en población mexicana. Se conformó una muestra de 1,047 estudiantes de secundaria (M=14.09; DE=2.29; 55.2% sexo femenino), a quienes se les aplicó la escala PANAS-N, la Escala de Depresión del Centro de Estudios Epidemiológicos CES-D y la Escala de Gaudibilidad para niños y adolescentes (EGNA) (moduladores del disfrute). Se corroboró la estructura interna de dos factores, Afecto Positivo (AP) y Afecto Negativo (AN) a través de un Análisis Factorial Confirmatorio (χ²(169) = 947.17; p<.001, CFI = .96, TLI = .95, RMSEA = .06, SRMR = .07) y los factores mostraron adecuados valores de consistencia interna (AP: α = .828 y w = .830, y AN: α = .819 y w = .820). Asimismo, las relaciones con las otras variables fueron las esperadas (AP correlación positiva y moderada con gaudibilidad, y AN correlación positiva con sintomatología depresiva), excepto la relación entre afecto positivo y sintomatología depresiva que no resultó significativa. La escala PANAS-N es un instrumento adecuado para evaluar el afecto positivo y negativo en población infantil y adolescente de la ciudad de Morelia (México).

Authors: González-Cantero Joel Omar , Oropeza Tena Roberto , Martínez Arriaga Reyna Jazmín
Published: November 2023

Introduction: the prevalence of diabetes mellitus in Mexican population is 12 %. Hemoglobin A1C (HbA1c) is the most important indicator of control of this disease, so it is required to develop psychological interventions to help people to control HbA1c. Objective: develop and evaluate a positive and cognitive behavioral intervention to control HbA1c in people with type 2 diabetes mellitus (T2DM). Method: eleven patients with T2DM were randomly assigned to an experimental group (EG; n = 6) or control group (CG; n = 5). The intervention consisted of 12 weekly sessions. Self-efficacy, hope, resilience, and optimism were measured with the Diabetes Treatment Self-Efficacy Instrument, Adult Hope Scale, Mexican Resilience Scale, and Life Orientation Test, respectively, along with an assessment of HbA1c, after intervention, and at a three-month follow-up. Results: clinically significant improvements on HbA1c after intervention (g = 0.426) and follow-up (g = 0.749), improvements in self-efficacy after intervention (g = 1.168) and follow-up (g = 0.873) were identified in EG. Discussion: clinically favorable, but not statistically significant, effects of the intervention were discussed; in addition, the role of study variables in HbA1c control is discussed. Conclusions: positive and cognitive behavioral intervention is a promising alternative to improve HbA1c and self-efficacy in people with T2DM. Thus, it is advisable to conduct further evaluation with randomized controlled trials.

Authors: Alvarez Ortega Syra
Published: November 2023

La Sección de Arquitectos Constructores fue el espacio donde se inició la educación en arquitectura en el Perú. La sección se creó en 1910 en la antigua Escuela de Ingenieros. Su creación fue el resultado de un proceso que se inició en las últimas décadas del siglo XIX y el primer graduado fue Emilio Harth Terré en 1925. En 1930 la Sociedad de Arquitectos encarga la elaboración de un Proyecto de Reforma y Ampliación de la Enseñanza de la Arquitectura en la Escuela de Ingenieros.Esta reforma permitiría intensificar el estudio de la Arquitectura con cursos más apropiados. El año siguiente se llevó a cabo, en la Escuela de Ingenieros, la reforma que dispuso los nuevos planes de estudios para todas las secciones. En este artículo se presentan los planes de estudios como evidencia de los primeros intentos y orientación académica para la concepción de una formación profesional con identidad propia y diferenciada de la ingeniería entre los años 1910 y 1931.

Published: November 2023

Las microceldas son una solución conceptual a áreas con alta densidad de tráfico. Un sistema celular jerárquico (microceldas dentro de macroceldas) CDMA, en el cual todos los canales detráfico son atendidos solamente por un único canal de radio en todas las celdas, y aplica soft handoff entre las celdas, muestra conectividad completa entre las microceldas y las macroceldasque las contienen sin degradación de la capacidad. Para mantener la tasa de handoff de un sistema celular como éste a un nivel aceptable, la movilidad de los usuarios debería ser usada paradeterminar la asignación a las celda. En este trabajo, se estudia el incremento de capacidad de un sistema celular jerárquico CDMA debido a la asignación a celdas basada en la movilidad de losusuarios. Tal como se expone en [3], usuarios de movilidad lenta, con velocidad vVo) deberían ser asignados a macroceldas. Por tanto, considerando el estudio anterior y las características de diseño propias de CDMA, un modelo es implementado, de cuya simulación en MATLAB son presentados los resultados junto con las conclusiones respectivas.

Fusarium Rot Biological Control of Citrus caused by Fusarium oxysporum
Authors: Dewi Ovilya Kusuma Minarma , Abadi Abdul Latief , Widyaningsih Sri
Published: November 2023

Fusarium oxysporum is a pathogen that causes Fusarium rot disease on citrus plants. The F. oxysporum is a soil-borne pathogen whose fungicide is not effective against it and difficult to cure. Thus, the use of Trichoderma spp. as one of the most effective and well-known biocontrol agents against many plant diseases in agriculture is needed. To test Trichoderma capabilities on the specific pathogen, method of this study consisted of isolation and rejuvenation of F. oxysporum and Trichoderma, morphological identification of the fungus, in vitro test of Trichoderma antagonistic ability against F. oxysporum on PDA medium, and in vivo test conducted in a green house on Rough Lemon (RL) and Japansche Citroen (JC) rootstock seeds to calculate the total disease incidence using a formula. The result of in vitro test of this study shows that 3 Trichoderma isolates (TJ, TKH, and TST) were able to inhibit the growth of F. oxysporum on PDA medium by 65.56%, 62.99%, and 61.19%, respectively. While in vivo test shows that the treatment of TJ isolates on RL seeds and TKH on JC seeds shows lowest disease incidence percentage of 3.33%. Therefore, this study proves that Trichoderma can be used as a biocontrol agent in controlling Fusarium rot disease in citrus plants. However, further research is needed to detect which Trichoderma species TJ and TKH isolates contain.

Authors: Zhao Lanlan , Li Jie , Li Pei , Zhao Xin , Ma Ningzhen , Zhang Songyun
Published: November 2023

BACKGROUND

Acute Intermittent Porphyria (AIP) is characterized by acute attacks of neurovisceral symptoms. Infection and negative emotions are factors that can trigger acute AIP attacks, thus avoiding these potential triggers can effectively reduce the risk of acute attacks. During the COVID-19 pandemic, online health education provides patients with a convenient and safe way to receive health education, thus effectively improving their quality of life（QoL）.

OBJECTIVE

We explored the effect of online health education on acute AIP attacks during the COVID-19 pandemic.

METHODS

This study retrospectively included 47 patients with AIP who were infected with COVID-19 and completed a questionnaire from November 2022 to March 2023. These participants were divided into two groups based on whether they had received centralized health education during COVID-19. The primary outcomes were acute AIP attacks, AIP attack severity, and QoL. Secondary outcomes were negative emotions and positive coping styles.

RESULTS

In comparison to the non-health education group, the health education group showed a significant decrease in the incidence of acute AIP attacks (P < .05), a reduction in the severity of AIP attacks (P < .05), and an improvement in QoL (P < .05). Additionally, the health education group had a significant decrease in negative emotions (P < 0.05) and a substantial increase in positive coping styles (P < 0.05).

CONCLUSIONS

Health education may enhance patients' cognition and coping skills, and reduce negative emotions, thereby reducing the occurrence and severity of acute AIP attacks, and improving the patients' QoL.
Ondel-Ondel Culture: People's Perception on the Shifting in Function and Value Degradation
Authors: Sihombing Lambok Hermanto
Published: November 2023

Ondel-ondel is one of Jakarta’s most prominent cultures. It is a giant doll made of woods and decorated  with cotton clothes and human-like embellishments. However, there has been a shift in the way people perceive its role. Ondel-Ondel, which was initially used in significant ceremonial contexts, has evolved into a tool for busking or street entertainment, or more commonly known as Ondel-Ondel Ngamen. At the moment, Ondel-Ondel Ngamen has captured big interest of online users on YouTube. There is a variety of comments on YouTube regarding the existence and representation of Ondel-ondel Ngamen. In this study, the author aims to evaluate YouTube comments regarding people's perceptions of the Ondel-Ondel culture. The author applies a qualitative approach by providing the data from the top-three Indonesian news-related YouTube channels; CNN Indonesia, KompasTV, and Metrotvnews. The dataset is taken from any other scholarly articles that support this analysis. In this study, the author utilizes Stuart Hall's encoding-decoding and commodification theories to evaluate how people perceive Ondel-Ondel, which has undergone a shift in function and value degradation. This study's findings indicate that Ondel-Ondel is vulnerable to commodification. It is no longer regarded as a sacred aspect of rituals or noteworthy occasions.

Authors: Misnadin Misnadin , Yuliawati Susi
Published: November 2023

Language attitudes play an important role in the use and maintenance of a language. This is particularly the case in a multilingual speech community such as the Madurese community where most people speak more than one language. The present study seeks to understand the attitudes of the Madurese community toward Madurese, Indonesian, English, and other foreign languages (MIEof languages). To achieve this, 200 questionnaires were randomly distributed to respondents in Bangkalan, Sampang, Pamekasan, and Sumenep, but only 150 questionnaires were filled in and returned. The questionnaires, which contained questions and answers using 5 point Likert scales of ‘strongly agree, agree, neutral, disagree, and strongly disagree’, were analyzed quantitatively by averaging the calculation results of each of the scales. The results were categorized based on relevant themes, i.e., attitudes toward learning, mastery, and use of MIEof languages. Our analyses showed that most of the respondents demonstrated positive attitudes toward learning, mastery, and use of MIEof languages. The results are discussed with respect to the language maintenance of Madurese and local languages, the prospects of Indonesian, English, and other foreign languages along with multilingualism practices in Madura. It can be concluded that the Madurese community seem to be open to the practice of multilingualism, indicated by their positive attitudes toward language learning, mastery, and use. It is suggested that future studies make use of qualitative data, such as interview data so that findings about the language attitudes of the Madurese community under consideration can be further corroborated.
