The Potential of Renewable Energy to Replace Diesel Power Plants in Supporting Energy Transition in Indonesia
Authors: Sugiyono Agus , Wirjodirdjo Budisantoso , Hilmawan Edi
Published: February 2024

The Indonesian government is committed to reducing greenhouse gas emissions under the Paris Agreement. One form of this commitment is the program to replace diesel power plants with renewable energy plants in the electricity sector. Fossil-based diesel power plant operations have disadvantages, such as relatively expensive generation costs and greenhouse gas emissions. There are three renewable energy technology options as potential substitutes for diesel power plants: a solar photovoltaic (PV) power plant integrated with a battery energy storage system (BESS), a small-scale geothermal power plant, and a micro-hydropower plant. This paper will analyze the prospects of each technology option based on its economic and environmental impact. Various technical parameters, including renewable energy potential and intermittent factors, as well as economic parameters such as investment and generation costs, are important factors for selecting prospective renewable energy generators. The analysis was carried out by calculating the levelized cost of electricity (LCOE), CO2 emissions, and oil fuel consumption for four different scenarios. The results of the analysis show that replacing the diesel power plants with micro-hydropower plants can reduce LCOE by 0.24 USD/kWh to 0.12 USD/kWh. The use of a solar PV power plant integrated with a BESS has the most potential to reduce CO2 emissions, which account for 54% of emissions from diesel power plants. Meanwhile, the potential for oil fuel reduction from this program can reach an annual average of 0.85 million kl.

Published: February 2024

Freshwater is essential in sustaining human life on the planet and the demand for potable water has increased for the past years due to population growth and modernization. However, the natural resources of water have become polluted/contaminated due to industrialization and other human activities. The development of membrane technology, especially with the creation of nanocomposite materials, provides a solution to treat polluted or contaminated water through various separation processes resulting in the production of clean water fit for human consumption. In this study, polysulfone was added with zeolite nanoparticles to fabricate nanocomposite membranes via non-solvent induced phase separation (NIPS) method to enhance the hydrophilicity and mechanical strength of the membrane suitable for water and wastewater applications. The nanozeolite was added in varying concentrations; 1% 5% and 10% and the fabricated membranes were characterized via Contact Angle Goniometer, universal testing machine (UTM) and scanning electron microscopy (SEM) to determine the contact angle, tensile strength, and surface morphology, respectively. Based on the characterization data, the 1% concentration showed the highest tensile strength and the lowest contact angle measurement. The 1% nanozeolite concentration is the optimum membrane formulation due to the enhanced hydrophilicity and mechanical strength of the material.

Published: February 2024

Introduction: Subfertility is a major life issue that affects the quality of life. Most of them are residing in developing countries. The prevalence of subfertility is an essential element to identify the magnitude of the problem in each country.Objective: To assess the prevalence of primary and secondary subfertility and its associated factors in the Colombo district, Sri Lanka.Methodology: This cross-sectional study used a stratified cluster sampling method to recruit 3104 married women aged between 15-49 in 38 urban and rural clusters in the Colombo district, Sri Lanka. The study was conducted in 2018-19 and used a structured questionnaire based on the clinical definition of subfertility.Results: The point prevalence of primary subfertility was 6.08 (95% CI:5.3-7.0). A significantly high prevalence of primary subfertility was reported among female partners with tertiary education (aOR:2.80; 95% CI:1.08-7.39) compared to primary or no education and employed women (aOR:1.88; 95% CI:1.37-2.57) compared to unemployed women. The point prevalence of secondary subfertility was 8.40 (95% CI:7.4-9.4). A significantly high prevalence of secondary subfertility was reported among female partners with tertiary education (aOR:2.55; 95% CI:1.16-5.59) compared to primary or no education, unemployed women (aOR:1.65; 95% CI:1.25-2.19) compared to employed women and women of other ethnic groups (aOR:1.97; 95% CI:1.13-3.32) compared to Moor ethnic group.Conclusion: The prevalence of both primary and secondary subfertility was 14.5% (95% CI:13.3-15.7) among the married women aged between 15-49 years in the Colombo Regional Director of Health Services area. The development of effective and rational public health policies for the prevention of subfertility and increased availability of advance reproductive technology facilities should be considered.

Introduction: Liver transplantation for paediatric patients was started in Sri Lanka in 2020, focusing on living donors. This retrospective study examines the donors evaluated at the Colombo North Centre for Liver Disease for the first twelve paediatric liver transplants.Methods: Related donors and undirected donors were encouraged. Donor assessment was done in stages: initial screening, haematological investigations, imaging, and ethical approval. Twelve donors were selected for ethical approval and donor surgery.Results: A total of 36 donors underwent workup. 24 were rejected, and 12 were accepted. The reasons to reject were abnormal LFTs and fatty liver disease 16 (67%), the presence of comorbidities 5 (21%), and unfavourable anatomy 2 (8%). In one donor (4%), surgery was abandoned due to rising intraoperative lactate levels. Of the rejected group, 17 were males and 7 were females, and the median age was 33 (Range 43-20) years. 12 donors (7 related and 5 non-related) had a median age of 33 (range 25-41) and a median BMI of 19.25 (16.3-22.5) and a male-to-female ratio of 7:5. Left lateral sector donation was done in 6 while left lobe donation in 4 and right lobe donation in 2 were done respectively.Conclusion: Fatty liver disease was the predominant cause of donor disqualification. Living donor paediatric liver transplantation is feasible in the Sri Lankan setting. It would be a safer option due to the detailed donor workup given the high prevalence of fatty liver disease in the population.

Published: February 2024

Globally, providing evidence on the economic burden of chronic obstructive pulmonary disease (COPD) is becoming essential as it assists the health authorities to efficiently allocate resources. This study aimed to summarize the literature on economic burden evidence for COPD from 1990 to 2019. This study examined the economic burden of COPD through a systematic review of studies from 1990 to 2019. A search was done in online databases, including Web of Science, PubMed/Medline, Scopus, and the Cochrane Library. After screening 12,734 studies, 43 articles that met the inclusion criteria were identified. General study information and data on direct, indirect, and intangible costs were extracted and converted to 2018 international dollars (Int$). Findings revealed that the total direct costs ranged from Int$ 52.08 (India) to Int$ 13,776.33 (Canada) across 16 studies, with drug costs rannging from Int$ 70.07 (Vietnam) to Int$ 8,706.9 (China) in 11 studies. Eight studies explored indirect costs, while one highlighted caregivers’ direct costs at approximately Int$ 1,207.8 (Greece). This study underscores the limited research on COPD caregivers’ economic burdens, particularly in developing countries, emphasizing the importance of increased research support, particularly in high-resource settings. This study provides information about the demographics and economic burden of COPD from 1990 to 2019. More strategies to reduce the frequency of hospital admissions and acute care services should be implemented to improve the quality of COPD patients’ lives and reduce the disease’s rising economic burden.
Cutting Edge: The Tetraspanin CD53 Promotes CXCR4 Signaling and Bone Marrow Homing in B Cells

Published: February 2024

B cell trafficking involves the coordinated activity of multiple adhesive and cytokine–receptor interactions, and the players in this process are not fully understood. In this study, we identified the tetraspanin CD53 as a critical regulator of both normal and malignant B cell trafficking. CXCL12 is a key chemokine in B cell homing to the bone marrow and secondary lymphoid organs, and both normal and malignant B cells from Cd53−/− mice have reduced migration toward CXCL12 in vitro, as well as impaired marrow homing in vivo. Using proximity ligation studies, we identified the CXCL12 receptor, CXCR4, as a novel, to our knowledge, CD53 binding partner. This interaction promotes receptor function, because Cd53−/− B cells display reduced signaling and internalization of CXCR4 in response to CXCL12. Together, our data suggest that CD53 interacts with CXCR4 on both normal and malignant B cells to promote CXCL12 signaling, receptor internalization, and marrow homing.

In contrast to the “helper” activities of most CD4+ T effector subsets, CD4+ cytotoxic T lymphocytes (CD4-CTLs) perform functions normally associated with CD8+ T and NK cells. Specifically, CD4-CTLs secrete cytotoxic molecules and directly target and kill compromised cells in an MHC class II–restricted fashion. The functions of these cells have been described in diverse immunological contexts, including their ability to provide protection during antiviral and antitumor responses, as well as being implicated in autoimmunity. Despite their significance to human health, the complete mechanisms that govern their programming remain unclear. In this article, we identify the Ikaros zinc finger transcription factor Eos (Ikzf4) as a positive regulator of CD4-CTL differentiation during murine immune responses against influenza virus infection. We find that the frequency of Eos+ cells is elevated in lung CD4-CTL populations and that the cytotoxic gene program is compromised in Eos-deficient CD4+ T cells. Consequently, we observe a reduced frequency and number of lung-residing, influenza virus–responsive CD4-CTLs in the absence of Eos. Mechanistically, we determine that this is due, at least in part, to reduced expression of IL-2 and IL-15 cytokine receptor subunits on the surface of Eos-deficient CD4+ T cells, both of which support the CD4-CTL program. Finally, we find that Aiolos, a related Ikaros family member and known CD4-CTL antagonist, represses Eos expression by antagonizing STAT5-dependent activation of the Ikzf4 promoter. Collectively, our findings reveal a mechanism wherein Eos and Aiolos act in opposition to regulate cytotoxic programming of CD4+ T cells.

Candida albicans grows rapidly when the microflora becomes imbalanced due to a variety of factors. Its ability to infect a host is aided by its virulence factors, such as biofilm. This study aimed to evaluate the activity of clover honey in inhibiting and degrading the biofilm formation of C. albicans in vitro. This study used a true experimental design with an in vitro post-test-only control group design approach. The microtiter plate assay was used to grow planktonic cells and biofilm. This method was carried out to obtain the Optical Density (OD) value for each test, measured by a Microplate Reader. Cell viability was measured using the MTS Assay kit, the biofilm matrix was measured using the Crystal Violet Assay, and the morphology of C. albicans biofilms was observed by scanning electron microscopy (SEM). Probit and One-way ANOVA tests were applied to determine the MIC50 of both planktonic and biofilm, as well as statistical analysis. The results showed that clover honey exerted inhibitory activity against C. albicans planktonic cells at a MIC50value of 31.60% w/v. At the highest concentration, clover honey exhibited antibiofilm activity by lowering the extracellular matrix and viability of C. albicans cells by 64.59% and 72.09%, respectively. Based on SEM observation, clover honey changed the cell morphology of C. albicans and reduced the thickness of the biofilm. Overall, our findings concluded that clover honey exhibited antifungal properties against C. albicans by inhibiting biofilm formation and degrading mature biofilm.

EMILIO GABBA E Lâ€™ANTICHITÃ€ NEL SETTECENTO
Authors: Cambiano Giuseppe
Published: February 2024

According to Gabba, the ancient literary texts were essential evidence for the modern historian of antiquity, because they provided a view on how the ancients themselves interpreted their historical reality. But, following the steps of Benedetto Croce and Arnaldo Momigliano, he judged equally essential the history of modern historiography and, more generally, of modern reflections on ancient societies. For this reason the Eighteenth-century appeared to Gabba as particularly relevant, because in this century the reflections on antiquity were strictly and vitally connected to political, social and economic problems of the present, particularly during the American Revolution. Gabba wrote therefore a series of essays on the discussions developed in this century about colonies, federalism and commerce between ancient and moderns and on outstanding intellectuals such as Adam Ferguson and John Adams. For this emphasis on political and economic problems Gabba distinguished himself from the perspective of Momigliano, more interested in questions of historical methods and antiquarianism, and connected much closer to the enquiries of Franco Venturi on European enlightenment.
Christene wat Joodse gebruike opneem: Die Hebrew Roots-leerstellings, beoordeel vanuit Handelinge 10:9-29, Handelinge 15:1-35 en Galasiërs 2 en pentekostalistiese hermeneutiek
Authors: Meyfarth Leonie , Nel Marius
Published: February 2024

Christians taking up Jewish Customs: The Hebrew Roots doctrines evaluated from Acts 10:9–29, Acts 15:1-35, Galatians 2, and Pentecostalist hermeneutics. Numerous Pentecostal and Christian adherents are encountering Hebrew Roots teachings, with a significant global presence, notably in the USA, Israel, Europe, South America, and South Africa. In 2012, the South had a substantial number of adherents. A prominent ministry, 119 ministries, offers an interactive map listing Hebrew Roots ministries worldwide. In South Africa, over 120 such ministries are listed, primarily in Gauteng and the Western Cape. Hebrew Roots proponents claim authenticity by reverting to Jewish and Mosaic roots, advocating adherence to Old Testament precepts, including rituals and customs. This article critically assesses these claims, focusing on key texts such as Acts 10:9-29, Acts 15:1-35, and Galatians 2, in the context of the Mosaic-Hebrew roots movement. This movement argues that non-Jewish Christians should observe the Mosaic laws integral to God’s covenant with Israel. Employing a comparative literature analysis and grammatical-historical exegesis, the study contrasts Pentecostal beliefs with those of the Hebrew Roots movement concerning non-Jewish Christians’ ethical responsibilities regarding the Mosaic laws. The article first outlines the historical evolution of the Hebrew Roots movement, emphasizing its theological foundations. Subsequent sections systematically analyse the scriptural passages, examining their influence on these movements’ doctrines through a Pentecostal hermeneutical lens. One central concern highlighted is the potential for Hebrew Roots teachings to challenge the exclusive role of Christ in salvation by emphasizing adherence to the Old Testament’s legal framework, raising questions about Christ’s divinity.Intradisciplinary/intradisciplinary implications: This research seeks to prompt a critical examination within the field of Dogmatics, specifically with regard to the precise delineation of a Christian’s obligations concerning the Mosaic Law, particularly in the context of the Decalogue.
Tertiary care center experience: An overview of primary mediastinal lymphomas
Authors: Maru Paheli , Brahmbhatt Beena , Vanik Sangita , Kakoty Sneha
Published: February 2024

Background:

Mediastinal lymphoma is uncommon, and only 10% of lymphomas occur primarily in the mediastinum. Very few Indian studies have discussed the frequency, presentation, and diagnostic approach of primary mediastinal lymphomas.

Aims:

This study aims to detail the frequency and histological features of mediastinal lymphomas diagnosed in our Institute, discuss the close differentials, and compare the morphological and immunohistochemistry (IHC) features of primary mediastinal lymphomas.

Settings and Design:

A retrospective observational study.

Materials and Methods:

Fifty-nine cases of primary mediastinal lymphomas diagnosed over 5 years using hematoxylin and eosin (H and E)-stained and IHC slides.

Statistical Analysis Used:

Descriptive statistics.

Results and Conclusions:

Forty-five (76%) cases had predominant involvement of the anterior mediastinum; Hodgkin lymphoma, and non-Hodgkin lymphoma constituted 12 and 47 cases, respectively. T lymphoblastic lymphoma comprises the most common primary mediastinal lymphoma. There is a marked difference between the demographic profiles of cases with primary mediastinal lymphomas in India and worldwide. A meticulous histological examination to direct a limited panel of IHC markers can help arrive at the final diagnosis in settings where molecular and cytogenetic studies are not performed.
Study of Association of Erectile Dysfunction in male subjects with the severity of Alcohol Dependence
Authors: Mehta Priyank Singh , Patra Priyadarshee , Tapasi Santosh
Published: February 2024

Background:

Alcohol dependence syndrome is a major public health problem, and it impacts the social, psychological, medical, economic, and religious spheres of our existence. Persistent alcohol abuse impacts sexual functioning negatively and leads to the onset of sexual dysfunction.

Aim:

This study was conducted to determine erectile dysfunction in males diagnosed with alcohol dependence syndrome and its association with the severity of alcohol dependence.

Materials and Methods:

The descriptive, non-interventional, cross-sectional study was conducted at the Department of Psychiatry in a tertiary care hospital where 78 subjects diagnosed with alcohol dependence syndrome were assessed for severity of dependence with the Severity of Alcohol Dependence Questionnaire (SADQ-C). Erectile dysfunction in these subjects was assessed with the International Index of Erectile Function scale (IIEF) and the severity of the same was correlated with the severity of alcohol dependence.

Results:

The results of our study indicated that erectile dysfunction was common in individuals having alcohol dependence syndrome and its severity was positively correlated with the severity of alcohol dependence. Unidentified sexual dysfunction may perpetuate alcohol dependence with poor response to deaddiction therapy. This information about sexual dysfunction due to alcohol dependence can also be used in motivational counseling of heavy drinkers to provide an impetus for change.

Conclusions:

The prevalence of erectile dysfunction was significantly higher than that of the general population. The same was significantly elevated in patients with severe alcohol dependence as compared to those with mild/moderate alcohol dependence.

Treatment of maxillary hypoplasia with bone anchored maxillary protraction (BAMP) - A case report
Authors: Vichare Sharvari , Vichare Gauri
Published: February 2024

Early diagnosis and treatment is known to be beneficial in Class III malocclusions secondary to maxillary hypoplasia. However, success of treatment largely depends on the patient’s compliance and thus, appropriate choice of treatment, appliance and the age for interception plays an important role. Bone anchored maxillary protraction is one such approach presented in this case report for a 13 years old boy who reported with the chief complaint of lower front teeth visibility during speech and smiling. On examination his molars were in Angle’s Class III relation, anterior crossbite and deep bite with unerupted maxillary canines. Orthodontic treatment was begun for deep bite correction and for creating space for the maxillary canines, followed by surgical intervention for placement of bone anchored miniplates. Protraction was done for 14 months and the total treatment time was 20 months. Improvement in the patient’s profile, aesthetics and function was achieved with well aligned arches.
Obstructive sleep apnoea and nocturnal atrial fibrillation in patients with ischaemic heart disease
Authors: Kuang Silin , Chan Yiong Huak , Wong Serene , Khoo See Meng
Published: February 2024

Introduction:

Arrhythmias, especially atrial fibrillation (AF) and ventricular arrhythmias, are independent risk factors of mortality in patients with ischaemic heart disease (IHD). While there is a growing body of evidence that suggests an association between obstructive sleep apnoea (OSA) and cardiac arrhythmias, evidence on this relationship in patients with IHD has been scant and inconsistent. We hypothesised that in patients with IHD, severe OSA is associated with an increased risk of nocturnal arrhythmias.

Methods:

We studied 103 consecutive patients with IHD who underwent an overnight polysomnography. Exposed subjects were defined as patients who had an apnoea–hypopnoea index (AHI) ≥30/h (severe OSA), and nonexposed subjects were defined as patients who had an AHI <30/h (nonsevere OSA). All electrocardiograms (ECGs) were interpreted by the Somte ECG analysis software and confirmed by a physician blinded to the presence or absence of exposure. Arrhythmias were categorised as supraventricular and ventricular. Arrhythmia subtypes (ventricular, atrial and conduction delay) were analysed as dichotomous outcomes using multiple logistic regression models.

Results:

Atrial fibrillation and AF/flutter (odds ratio 13.5, 95% confidence interval 1.66–109.83; P = 0.003) were found to be more common in the severe OSA group than in the nonsevere OSA group. This association remained significant after adjustment for potential confounders. There was no significant difference in the prevalence of ventricular and conduction delay arrhythmias between the two groups.

Conclusion:

In patients with IHD, there was a significant association between severe OSA and nocturnal AF/flutter. This underscores the need to evaluate for OSA in patients with IHD, as it may have important implications on clinical outcomes.
Approach to difficult-to-treat asthma in childhood: a narrative review
Authors: Cheng Duo-Tong , Wee Liang Yi Justin , Teoh Oon Hoe , Thomas Biju
Published: February 2024

Asthma is a major chronic disease affecting children, and children with difficult-to-treat asthma account for a disproportionate share of resource utilisation and healthcare costs. This review presents a comprehensive and up-to-date overview of the treatment strategies in difficult-to-treat paediatric asthma. Mimickers of asthma must first be ruled out, and the diagnosis confirmed with objective tests whenever possible. The effect of comorbid conditions such as obesity, smoking, other atopic conditions and psychosocial factors on asthma control and severity should be considered. Treatment can then be optimised by implementing personalised strategies, including the use of appropriate drug delivery devices and adherence monitoring. Biologics can be an alternative treatment option for selected patients but should not be a substitute for addressing poor adherence. Many patients with difficult-to-treat asthma may not have severe asthma, and the physician should work with patients and families to achieve good asthma control via an individualised approach.
The four operations on perverse motives

Published: February 2024

Let

k

be a field of characteristic zero with a fixed embedding

\sigma:k\hookrightarrow \mathbf{C}

into the field of complex numbers. Given a

k

-variety

X

, we use the triangulated category of étale motives with rational coefficients on

X

to construct an abelian category

\mathscr{M}(X)

of perverse mixed motives. We show that over

\mathop{\mathrm{Spec}}(k)

the category obtained is canonically equivalent to the usual category of Nori motives and that the derived categories

\mathrm{D}^{\mathrm{b}}(\mathscr{M}(X))

are equipped with the four operations of Grothendieck (for morphisms of quasi-projective

k

-varieties) as well as nearby and vanishing cycles functors and a formalism of weights. In particular, as an application, we show that many classical constructions done with perverse sheaves, such as intersection cohomology groups or Leray spectral sequences, are motivic and therefore compatible with Hodge theory. This recovers and strengthens work by Zucker, Saito, Arapura and de Cataldo–Migliorini and provides an arithmetic proof of the pureness of intersection cohomology with coefficients in a geometric variation of Hodge structures.

Published: February 2024

Mosques have an important role in the spiritual value of Muslims. The effort to transform the Mosque into a multifunctional center that contributes to the welfare of Muslims in Medan City is a step in restoring the center of Islamic civilization in the Mosque. This condition can be realized with the independence of the Mosque that does not depend on aid. The problems of welfare around the Mosque, infrastructure, and legal issues faced by the Mosque in Medan City are obstacles to bringing independence. Independent Mosques that aim for social welfare and economic development of the community around the Mosque have challenges in their development. The research method used in this study was descriptive qualitative and involved collecting data from interviews, observations, and document analysis. The research findings show that in strengthening the identity of Muslims, independent mosques have a positive impact on encouraging community welfare and overcoming social problems in the environment around the Mosque. The motivation of the Mosque manager determines the
quality of service in providing education, economic empowerment, and health. The intensity of collaboration in encouraging independent Mosques can increase community independence and trust as a step towards making the Mosque not only a place of worship, but also a center of Islamic civilization. It is important to ensure the benefits of sustainable social impact by fulfilling the criteria of an independent Mosque in providing religious services and maintaining religious values.

Published: February 2024

Este artigo propõe uma análise da performance cênica Cross-dresser na televisão brasileira, especificamente em programas de auditório, através da atuação do ator Jorge Lafond na pele de sua personagem Vera Verão. O objetivo é lançar um olhar crítico sobre como os estereótipos emergem nessas redes, assumindo posições de personagem, e como isso contribui para a naturalização da figura destacada no processo de inserção social. Exploraremos de que maneira a atuação de Lafond construiu repertórios e redes de sociabilidade, examinando o papel dessa representação na dinâmica social do período em questão. Ao focar nessa expressão artística na televisão brasileira, busca-se entender como a performance de Cross-dresser não apenas entreteve o público, mas também desafiou normas sociais, contribuindo assim para projetos anti-hegemônicos dentro do cenário midiático latino-americano do século XX.
Pensar a América Latina – Cultura, Arte, Intelectuais e Meios de Comunicação

O presente dossiê propõe reúne artigos que abordam a circulação de ideias de grupos vinculados aos campos das artes, letras, ciências e política na América Latina a partir de discussões que circundaram o debate de projetos nacionais, com ênfase na atuação em diversos meios de comunicação, como jornais, revistas, televisão e rádio. Com isso, aqui propomos uma reflexão ao largo do século XX, durante períodos autoritários (seja em momentos ditatoriais, seja em momentos de tensão na implantação de projetos nacionais em momentos de estabilidade democrática.) no qual artistas e intelectuais latino-americanos conceberam projetos e construíram redes de sociabilidade pensando uma ação anti-hegemônica. Assim reunimos trabalhos que debatem a realidade latina por pesquisadores de toda a América Latina, sobretudo brasileiros e argentinos. Do ponto de vista teórico-metodológico, este dossiê  se debruça na História Social da Cultura, situando os espaços de atuação construídos por diversos agentes a partir de projetos que buscaram alternativas para as tradições autoritárias e imperialistas presentes até agora nos Estados-nacionais. Tal reflexão nos parece salutar para repensar os campos de disputa e concepção do que é a construção do ser latino-americano, qual o papel do nosso continente nas redes intelectuais e artísticas, na proposição de projetos que dialogaram com as particularidades sociais do nosso espaço geográfico, da atuação nas brechas, das negociações e de como é crucial retomar à luz do século XXI outras formas de pensar os projetos nacionais e as discussões de ideias que resultaram na tradição intelectual de esquerda latino-americana.

Introduction. With the recent transition to online learning due to the COVID-19 pandemic, students experience academic difficulties, which affect their wellbeing. There is a need for an online wellbeing intervention program for students to address such concerns. This study aims to evaluate the feasibility and effectiveness of a six-week online educational wellbeing program for the physical and mental wellbeing of the University of Santo Tomas College of Rehabilitation Sciences (UST-CRS) students.

Methods. This is a quasi-experimental one-group pretest-posttest study that recruited UST-CRS students without physical and mental conditions. Physical and mental wellbeing modules developed by experts were deployed using Wix. The International Physical Activity Questionnaire Short Form (IPAQ-SF) and World Health Organization-Five Well-Being Index (WHO-5) were used for wellbeing assessment, while the Website Grader Tool and survey were used for website evaluation. Descriptive and inferential statistics, like Wilcoxon Signed Rank test and effect size, were conducted using JAMOVI. Alpha was set at 0.05.

Results. Seventeen students participated in the online wellbeing program. Results revealed statistically significant difference in the pre and post intervention IPAQ-SF scores on MET-minute for walking (p=0.04; 95% CI=647-1955), total MET-minute activities (p<0.01, 95% CI=259-2412), andWHO-5 scores (p=0.05; 95% CI=4.36-36.5), with effect sizes of Cohen’s d=0.43-0.71. Participants reported satisfaction with the modules, platform, and organizers despite inconsistent attendance.

Discussion. The online wellbeing program is feasible and effective in increasing the physical and mental wellbeing of the students. The findings of this study may guide future experimental studies for online wellbeing programs for university students.

Published: February 2024

Un proyecto de investigación “Interconnected inequalities and family life courses in Spain” (INTERINEQ) liderado por Andrés Castro, investigador del Centre d’Estudis Demogràfics, ofrece una mirada nueva sobre la transición a la vida adulta y la baja fecundidad en España. Desde una perspectiva cuantitativa y multivariada, esta investigación identifica seis clases sociales entre personas de 29 a 35 años en España: Una clase alta consolidada, tres clases medias, y dos clases populares. La investigación muestra que tanto los planes de formación familiar, como su ejecución dependen de estas clases sociales, en particular, de las ventajas o desventajas relativas al interior de las clases medias. Estas desventajas relativas se asocian a una emancipación y formación de pareja tardías, y a un número de hijos menor al deseado. En los sectores populares, no se observan patrones de formación familiar tardíos, ni tampoco brechas de fecundidad.

A simulação é uma técnica na qual, a partir da reprodução de acontecimentos reais, incluindo instrumentos, artefatos e produtos com os mais variados propósitos, proporciona-se o conhecimento e/ou treinamento dos usuários. Essa técnica permite prever e corrigir resultados, diminuindo ou eliminando os possíveis riscos oriundos envolvidos na experiência real. Apesar de ser utilizada em diversas áreas e disciplinas de cursos superiores, sua estruturação como prática pedagógica é recente sendo atualmente denominada como Ensino Baseado em Simulação. O Ensino Baseado em Simulação é fundamentado nas teorias cognitivas de aprendizagem, principalmente na Teoria da Aprendizagem Significativa, de Ausubel, e na Teoria da Aprendizagem Experiencial de Kolb. Sua característica principal é fornecer os meios para que práticas e experiências, cujo desenvolvimento demandam altos custos ou situações de risco elevado, possam ser executadas com precisão e acuidade sem causar nenhum dano, possibilitando o treinamento e correção de erros e hábitos, tornando o usuário capaz de realizar tarefas com mais confiança e desenvoltura. Nesta breve revisão sobre o uso da simulação didática em treinamentos e no processo de ensino-aprendizagem, descrevemos os principais conceitos do EBS, suas aplicações e perspectivas como estratégia de ensino centrada na atividade do aluno e que leva em conta sua profissionalização a partir do ensino na prática experimental.

Os conteúdos de Biologia são ensinados, em muitos casos, através de esquemas que facilitam o entendimento de determinados conceitos através da visualização abstrata de estruturas, à exemplo disso temos as estruturas celulares, como as organelas ou a própria molécula de DNA. Além disso, os esquemas no ensino de Biologia também são usados para sintetizar e representar determinados aspectos da natureza que ocorrem em larga escala, como o ciclo da água ou até mesmo o ciclo do nitrogênio. Um conteúdo que é comumente representado através de esquemas é o de cadeias alimentares, onde podemos visualizar em uma única figura, a posição de diferentes organismos enquanto produtores, consumidores primários, secundários, terciários, quaternários e decompositores. Além disso, também é possível sintetizar o fluxo energético dentro dessa mesma cadeia, através de simples conotações em um desenho. O presente trabalho objetiva descrever os processos de uma atividade realizada numa disciplina de mestrado, onde os participantes, após terem contato com um texto tratando sobre o conteúdo de cadeias alimentares, foram estimulados a elaborar um esquema que representasse uma determinada cadeia. Os desenhos elaborados pelos participantes foram analisados a partir da análise imagética, onde foi possível perceber a representação de diferentes aspectos em uma cadeia alimentar. Alguns participantes além de representar uma cadeia alimentar básica, desenharam cadeias de ambientes aquáticos e até mesmo incluíram uma certa complexidade, conferindo aspectos de uma teia alimentar ao esquema. Dessa forma, é possível identificar diferentes níveis de conhecimento acerca de um determinado conteúdo através da análise imagética aplicada a desenhos em sala de aula.

O presente estudo aborda a Educação Nutricional no Ensino Fundamental. Observou-se que na primeira série do Ensino Fundamental de uma escola privada em Belém do Pará a ocorrência de problemas como a obesidade, má qualidade da alimentação e ausência de informação sobre a importância de uma alimentação adequada, o que demandou a elaboração de uma intervenção pedagógica que alcançasse os alunos. Desta forma, o projeto “Educação Nutricional no Ensino Fundamental” foi aplicado objetivando refletir sobre as contribuições da educação nutricional no Ensino Fundamental para a compreensão das características e relevância de uma alimentação saudável que auxilie a mudança de rotina alimentar entre os alunos Ensino Fundamental de uma escola em Belém, Pará. A pesquisa adotou uma abordagem qualitativa, por meio uma pesquisa-ação e revisão bibliográfica realizada entre os meses de agosto e outubro de 2022. O aporte teórico contou com as contribuições de Maldonado et al (2021), Stocco Padilha (2023) e Schwingel e Araújo (2021). Ao fim das semanas de intervenção observou-se que as ações educativas despertaram nos educandos a sensibilização quanto a importância da adoção de uma alimentação saudável como estratégia de obtenção de uma melhor qualidade de vida. A avaliação se deu por meio de análise dos portfólios construídos a partir dos trabalhos dos estudantes. O estudo possibilitou destacar a saúde enquanto tema transversal que colabora para que os alunos compreendam as características e relevância de uma alimentação saudável, produzindo assim modificações de sua rotina alimentar. A educação em saúde se configura como ponto de partida para desenvolver o interesse por obter conhecimento que instrumentalize o estudante para uma educação que contribua para uma melhor qualidade de vida.

Este trabalho é sobre a Educação Inclusiva no Ensino de Ciências, nos anos iniciais do Ensino fundamental, tendo como objetivos: Geral: Analisar a relação entre a formação dos professores que ensinam Ciências nos anos iniciais e suas práticas pedagógicas relacionadas a inclusão de educandos com deficiência. Específicos: Identificar as práticas docentes desenvolvidas pelas professoras nas aulas de Ciências voltadas a inclusão desses educandos com deficiência; Descrever o processo formativo das professoras que ensinam Ciências nos anos iniciais do Ensino Fundamental; Discorrer sobre as práticas pedagógicas voltadas aos educandos com transtorno do espectro autista -TEA e transtorno do déficit de atenção com hiperatividade-TDAH. Este trabalho é uma pesquisa de Mestrado em desenvolvimento, a partir de uma abordagem qualitativa, a pesquisa está sendo realizada em uma escola pública municipal na cidade de Serra Talhada – PE, os dados serão produzidos por observação nas aulas de Ciências de duas turmas do 5° ano do Ensino Fundamental e por entrevistas semiestruturadas que serão realizadas com as professoras que ensinam Ciências nessas turmas e a gestora da instituição, utilizará a análise de discurso para tratamento desses dados. Os resultados iniciais indicam que ainda são poucos os educandos com deficiência que recebem auxílio de mediadores e os que possui o TDAH não contam com esse auxílio. No município tem 660 educandos com deficiência, dos quais 149 com Autismo e 136 com TDAH. E que o número de matrículas de educandos com deficiência tem crescido nos últimos anos no município, assim, como no país como um todo. Indicam também a necessidade em formação continuada que aborde a temática da inclusão, e mais incentivo ao Ensino de Ciências que muitas vezes tem seus conteúdos e aulas substituídos pelos de Linguagens e Matemática, devido as avaliações externas.
