Published: June 2023

El objetivo es presentar la base teórica y describir la práctica empírica de la metodología de investigación sobre el impacto social del turismo en el área de La Habana, trabajadoras sexuales, criminalizadas como prostitutas/jineteras. La epistemología de la fenomenología de Husserl y la dialéctica de Kosik dan lugar a la observación participante como metodología de inserción en el tejido social como "turista"/investigador, en busca de los significados que se establecen en los acercamientos "no autorizados" de los indígenas y los relación entre esencia/totalidad del fenómeno. La hipótesis o intuición esencial: tal recorrido en la investigación sociológica del fenómeno social del turismo es legítimo como opción teórico-metodológica. Potencia su continuo desarrollo como estrategia de aproximación e indagación en cualquier contexto geopolítico y socioeconómico. La relación entre el concepto de lugar y la observación participante es fundamental, como método y técnica de investigación consistente. En una perspectiva histórica y teórica, trazo la coyuntura geopolítica, económica y social en la que Cuba se abrió como destino turístico internacional, escenarios de praxis investigativa empírica. Los datos etnográficos recogidos con inspiración fenomenológica, especialmente sobre el significado de los actores sociales que me brindaron entrevistas en profundidad, son reportados desde sus narrativas. Como el método dialéctico continúa cuando termina el fenomenológico, los contextualicé histórica y políticamente para inferir generalizaciones. Inserto datos de la situación actual, buscando reforzar la necesidad del desarrollo de la metodología emprendida en Sociología del Turismo.

Published: June 2023

This study set out to analyze cultural ethnicity from a multicultural perspective, focusing on its role as a historical identity in the new Ecuadorian generations and its transcendence in their actions. We used a mixed methodology combining quantitative and qualitative techniques and expert opinion, in a descriptive research framework. To collect data, we used the survey technique and processed the results with IBM SPSS 25 software. This methodology was crucial to verify the basis of historical identity in the new Ecuadorian generations, standing out as a reference that incorporates the values of multiculturalism. In addition, it was identified that, as a cultural process, respect and autonomy in the expression of ethnic identity -considering its cultural, social and religious manifestations- represents a challenge for these generations. This finding emphasizes the importance of understanding and respecting the individual reality of each ethnic group in contemporary Ecuador

Authors: Singh Rashmi , Niranjan Shreyasi , Nagar Sasya
Published: June 2023

Water plays a crucial role in sustaining human life but the ramifications of urbanization and industrialization result in the contamination of water sources, rendering them unsuitable for drinking and agricultural purpose. Ponds are classified as lentic water bodies, which get adversely affected by anthropogenic activities. The current investigation endeavours to assess the physico-chemical properties of the water of Mahil pond, a freshwater pond situated in the middle of the city (Orai). The present work was conducted over the period of 12 months, specifically from January 2022 to December 2022. Monthly data have been gathered and subsequently organized by season, accompanied by its specific standard deviation. The study encompassed various parameters, including water temperature, pH, dissolved oxygen, Biochemical Oxygen Demand, Total alkalinity, Total Hardness, Nitrate-Nitrogen, and Phosphate. The findings of the current investigation revealed that the alkalinity level of the pond water exceeds the acceptable threshold established by the World Health Organisation. However, some of measured variables fall within the permissible range but many of them fall beyond the permissible limit. It is evident from the present study that, the water present in the Mahil pond is located at a position that falls slightly below the pollution threshold, rendering it unsuitable for both drinking purposes and the sustenance of resident organisms. Enhancing the quality of pond water can be achieved through the mitigation of anthropogenic activities and the prompt implementation of municipal treatment.

El T-MEC y la propiedad sobre hidrocarburos [2.3174]
Authors: Morales Medina Sydney Edson
Published: June 2023

El capítulo 8 del Tratado entre los Estados Unidos Mexicanos, los Estados Unidos de América y Canadá (T-MEC) reconoce el dominio directo y la propiedad inalienable e imprescriptible del Estado respecto de los hidrocarburos mexicanos. Este trabajo pretende comprender este capítulo (1) desde la perspectiva de la metamorfosis de los acuerdos de inversión, (2) su relación con otros capítulos del T-MEC y (3) su vigencia para el Gobierno mexicano. El informe concluye que (A) el capítulo 8 es la respuesta a la incertidumbre actual del régimen internacional de la inversión extranjera y de la necesidad de ajustar los tratados de inversión; (B) el reconocimiento de la propiedad mexicana de los hidrocarburos se realiza a través de contratos gubernamentales que no interfieren con las protecciones generales para las inversiones previstas en el T-MEC; y (C) el capítulo 8 no parece una herramienta efectiva para el Gobierno mexicano porque ciertas limitaciones presentes en otras partes del acuerdo continúan aplicándose al sector de hidrocarburos, como la obligación de otorgar el mismo trato a los inversionistas estadounidenses y canadienses que a los mexicanos. Finalmente, se pone en evidencia que el capítulo 8 del T-MEC no parece ser un buen modelo a seguir para el caso boliviano.

Osobe kasne životne dobi koje žive u okviru vlastitih kućanstava, skupina su koja svojim potrebama i udjelom u općoj populaciji zaslužuje veliku pažnju znanstvenika i stručnjaka. Cilj ovoga istraživanja je ispitati neke sociodemografske odrednice kvalitete života osoba kasne odrasle dobi koje žive na području Slavonije. U istraživanju je sudjelovalo N=692 osoba (62,5% žena) prosječne dobi 73,98 (SD=6,398) godina. Ispitanici su odgovarali na pitanja o sociodemografskim karakteristikama i na Upitnik kvalitete života (WHOQOL – BREF, 1998) Svjetske zdravstvene organizacije. Upitnik mjeri četiri domene kvalitete života: tjelesno zdravlje, psihičko zdravlje, socijalne odnose i okruženje. Rezultati su pokazali zadovoljavajuću kvalitetu života osoba kasne odrasle dobi, pri čemu su se slične odrednice pokazale značajnima za različite domene kvalitete života. Iz rezultata je vidljivo kako muškarci (čak i kada je varijabla dob kontrolirana), mlađi ispitanici, ispitanici koji su u vezi/braku (za razliku od samaca i udovaca), ispitanici s višim stupnjem obrazovanja, materijalno neovisni, koji imaju stalne prihode mirovine, te ne boluju od kroničnih (fizičkih/psihičkih) bolesti, izvještavaju o višim razinama kvalitete života vezane uz tjelesno i psihičko zdravlje, te okruženje. Kvaliteti socijalnih odnosa, osim već navedenih varijabli, doprinosi i roditeljski status. Za razliku od mjesta stanovanja (grad/selo) koje se nije pokazalo značajnom odrednicom niti za jednu domenu kvalitete života, članstvo u udruzi ili KUD-u pozitivno doprinosi kvaliteti života.

Assisting Healthcare Using a Time-Series-Based Nonstationary Model for Smart Beds
Authors: Maddeh Mohamed , Ayouni Sarra , Al-Otaibi Shaha , Alazzam Malik Bader , Alturki Nazik , Hajjej Fahima
Published: June 2023

Under any medical circumstance, the first and foremost requirement is to monitor physiological factors such as heart rate, blood pressure and oxygen level. Any breakdown in their coupling has been linked to ageing or illness. These physiological signals are nonstationary, and this paper analyses the transfer functions of nonstationary multidimensional time series of physiological signals. In this work, a method that integrates physiological modelling and functional elements into the smart bed for patients is proposed. This work includes experimentation on 10 smart bed patients. The proposed idea is validated and analysed to automatically capture any changes in the physiological signals due to postural changes, any impact of ageing or any requirement of a medical emergency. Next, it is demonstrated that the proposed method can be used to identify transient changes linked to medical emergencies for the given time-series data. These findings show the value of the proposed method in predicting the complicated vital-sign processes where conventional manual autoregulatory systems may fail in both healthy and pathological situations. The relation between the time series of physiological signals is an essential study field. A reliable time-varying model is presented to account for the possible nonstationarity of physiological data to determine the possibility of emergency care for patients. The suggested approach can identify variations and relations between signals because it is built as a dynamic model based on time-varying parameters. The technique used in this research includes readings of heart rate, blood pressure and oxygen level connected to the patient’s smart bed. The paper includes transient analysis and parametric evaluation as part of this work.

Drug repurposing is a term applied to finding a new therapeutic and pharmacological indication for an existing drug molecule with a known indication. Repurposing existing drugs to treat both rare and widespread ailments is more and more compelling due to the use of less risky compounds, which may result in lower entire development costs and quicker development timelines. This is due to the high attrition rates, high cost, and slow new drug discovery and development pace. The introduction of computational techniques and their advancements in drug design, discovery, and development has provided a platform for scientists to kick-start drug repurposing with ease. Computational approaches have provided rationality in drug repurposing, reducing the chances of failure in drug repurposing attempts. In this chapter, we present techniques for drug repurposing that are both conventional and computational, talk about the difficulties faced by scientists who attempt drug repurposing, and suggest creative solutions to these difficulties to help drug repurposing reach its full potential.
New Insights into Major Seismic Events by Coulomb Stress Change Pattern and Aftershock Distributions – Implication for Active Tectonics
Authors: Nedaei Mahnaz
Published: June 2023

Identification of the fault plane of earthquakes can be a critical contribution of seismology to regional tectonic studies and assessment of expected deformation and damage patterns. A fundamental ambiguity in the representation of an earthquake with a focal mechanism is to recognize the causative fault plane accommodating the slip during the event among the two nodal planes. The Coulomb static stress has been commonly used to determine the stress distribution induced by an event. However, for the first time in this research, the Coulomb regional stress was resolved on nodal planes to realize the optimally oriented plane for failure having maximum Coulomb stress on which the regional stress triggers an event. The method has been conducted for the April 5th, 2017 Sefidsang earthquake in NE Iran. The results reveal that the earthquake-triggering fault is a northeast-dipping listric fault with dextral reverse movement. The identified structural aspects subjected to active deformation in the area have crucial implications for seismic hazard assessment of the region and potential future failure areas.
Perspective Chapter: Emotion Detection Using Speech Analysis and Deep Learning
Authors: I. Iliev Alexander
Published: June 2023

Speech reflects the sentiment and emotions of humans. People can identify the emotional states in speech utterances, but there is a higher chance of perception error, which is generally termed as human error to identify the proper emotion when only using speech signals. Thus, artificial intelligence plays an important role in the detection of emotion through speech. Deep Learning is the subset of Machine Learning (ML) and artificial intelligence through which speech signal processing can be performed and the detection of emotions can be accomplished using speech. In this chapter, the classifiers of Machine Learning and Deep Learning will be reviewed. From the comparison in various studies and performances we will conclude what methods work better than others. We will discuss the limitations of these approaches as well. Accuracy scores will be discussed for each proposed system.
Structural Design of a Single-Family Residential Dwelling Using Cross-Laminated Timber (CLT)
Authors: C. Jellen Anthony , M. Memari Ali
Published: June 2023

Driven by desire to reduce carbon footprint in building construction that in modern times has relied heavily on masonry and concrete whose production is associated with burning excessive amounts of fuel, use of wood offers the ideal alternative. Cross-Laminated Timber (CLT) is an esthetically pleasing, mass-timber panelized product that offers users a cost-effective, renewable, durable, fire-resistant alternative to traditional building materials, such as masonry, concrete, and light-framing. A significant benefit to developers and community stockholders in the USA is that the raw materials required to produce CLT can be obtained domestically in timber rich rural areas, helping job growth in those areas, shortening supply chains, and reducing reliance on imported materials. The prefabrication process used to fabricate CLT panels provide users of the construction materials access to all the advantages offered by off-site construction methods such as factory quality control, just-in-time delivery, and accelerated construction. In this chapter, the original light-framing system of a traditional style single-family residential dwelling is converted to a panelized CLT structural support system. The chapter provides the basis of design, typical design process, and explains the challenges associated with using the alternative framing system.
Exploring the Role of Microbial Live Factories in Post-Harvest Management of Potatoes-Possible Solution to the Optimization of Supply Chain
Authors: Mansotra Pallavi
Published: June 2023

Potato (Solanum tuberosum L.) is the fourth most important food crop in the world with annual production of nearly 300 million tonnes. However, significant amount of the product (20–25%) is compromised to postharvest losses. Significant amount of the product (20–25%) is compromised to postharvest losses, therefore, alleviation of food security problems can be achieved through reduction in postharvest losses. Role of plant growth-promoting (PGP) microbes for the enhancement of potato production has been subject of extensive research. However, their impact on postharvest quality of horticultural crops has largely been unexplored, with limited research conducted on plant–microbe interactions in postharvest crops and their impact on storage stability. Although, microbial control has emerged as one of the most promising alternatives to chemical fungicides in several studies, however, significant research and development are required in development of sustainable microbial bio formulations for effective management of the crops under storage, in keeping with the quality of the produce. Therefore, manipulation of the bacterial microbiome, specially during crop storage, might provide microbial solutions as cleaner and sustainable alternatives to chemicals for plant production along the whole food chain. This chapter would elucidate functional analysis of the dynamics and potential of microbial live formulations for reducing the crop losses due to various diseases and status of the crop
Perspective Chapter: Mechanistic Understanding of Stability and Photocatalytic Efficiency of Titanium Dioxide Nanomaterials in Aquatic Media – A Sol-Gel Approach
Authors: Ghosh Saptarshi , Sahu Manoranjan
Published: June 2023

Titanium dioxide (TiO2) nanoparticles enhance the intrinsic value of commercial products like various cosmetics, paints, self-cleaning products, etc. Several research on the fabrication of TiO2, stabilization of TiO2 to retain its nanometric scale and increasing the inherent property of the material (i.e., photocatalytic) is ongoing for the last few decades. Still, the synthesis of highly efficient, stable, reproducible and cost-effective TiO2 nanoparticles remains a grand challenge for the researchers and scientific community. Further research is needed to develop an in-depth understanding of synthesis, aggregation kinetics and efficiency to improve the performance of TiO2 nanomaterial for the degradation of persistent organic pollutants (POPs). In this book chapter, we have summarized the synthesis process using the sol-gel pathway followed by its stability behavior and photocatalytic activity in the aqueous solutions. This study also highlighted the effects of various process variables such as pH, catalyst concentration, inorganic species etc. in the photocatalytic performance of TiO2 nanoparticles. Finally, we have reviewed various strategies that have been performed for increasing the photocatalytic efficiency of TiO2 by overcoming its limitations.

Authors: Bukunmi Ogunro Olalekan , Ruth Olasehinde Oluwaseun
Published: June 2023

Respiratory failure, characterized as the unsuccessful maintenance of adequate gas exchange, is associated with abnormalities of arterial blood gas tensions. The coronavirus disease-2019 (COVID-19) is majorly a respiratory disease capable of causing infection caused by the newly discovered coronavirus (SARS-CoV-2) with a consequential effect on respiratory failure. Simply put, respiratory failure is the major clinical demonstration of COVID-19 and the frontline cause of the associated mortality. Respiratory failure instigated by COVID-19 has some clinical features in affected patients. Disorders of the respiratory neuromuscular, airway, pulmonary vesicles, and lung parenchyma all manifest in COVID-19. These features are heterogeneous and categorized into progressive respiratory distress and unique “silent hypoxemia” as two phenotypes. Knowing the exact phenotype in patients with COVID-19 has been of important clinical significance in seeking the right treatment strategies for treating respiratory failure. The chapter will, therefore, provide more insights into the pathophysiology, clinical attributes, pathogenesis, and treatment approach of respiratory failure in COVID-19 conditions, as well as evaluate any similarities and differences that may exist.
Synthesis of Some Functional Oxides and Their Composites Using Sol-Gel Method
Authors: Hassen Arafa , M. El Sayed Adel , Al-Ghamdi Azza , Shaban Mohamed
Published: June 2023

Two main approaches for nanomaterials fabrication are the top-down and the bottom-up methods. The first is limited to mechanical grinding, thermal evaporation, ion sputtering, arc discharge, pulsed laser ablation, and other physical and chemical vapor deposition. These routes are costly, consume higher energy, and require complex technology such as ultrahigh vacuum. The bottom-up methods refer to the production of complex nanostructured materials from atoms and molecules. This approach is relatively simple and low in cost. However, it requires a good knowledge of the optical properties of the particles and their modifications when the particles are integrated with nanostructures. One of the widest bottom-up methods is the sol-gel. It involves a solution or sol (single-phase liquid) that undergoes a sol-gel transition (stable suspension of colloidal particles). In this chapter, we throw light on the history of sol-gel, its advantages, and limitations, operating this method for the production of different types of nanomaterials in the form of powders or thin films. In addition, some applications of the sol-gel-derived nanosized materials will be discussed.

Authors: Garcia João , Cerdeira Rita , Coelho Luís
Published: June 2023

The aim of this work was to study the impact of temporal lag between the exposition to air pollutants and the children admitted to the emergency room of Hospital Nª Srª Rosário pediatric service, in Barreiro, Portugal, with symptoms of respiratory problems. The two variables were recorded by the medical staff and by an air quality monitoring station, in the same periods. From the results, a moderate correlation between different symptoms of respiratory diseases (sdr, cough, and asthma) and pollutants was found, reaching maximum values after temporal lags of 2 to 6 days. The strongest correlation for lag 0 (consequences on the same day) rises for the symptomatology of asthma, reaching the highest values for COmax (ρ = 0.26) and COpeak (ρ = 0.25). Also, an important correlation was found for NOx, NOx med and peak NOx (ρ = 0, 21). The correlation with PM10 shows an unrepresentative value (ρ = 0.09), being negative for O3max (ρ = −0.23) and O3peak (ρ = − 0.22), as well as for SO2med (ρ = −0.12). Considering temporal lags of 1 to 8 and 15 days, overall, the maximum correlations between symptoms and NO, NO2, NOx, CO, and PM10 occur after temporal lags of 2 to 6 days, being constant or negative to SO2 and O3.
Use of Cardiac Troponin for the Diagnosis of Cardiac Pathology in Postmortem Samples Taken at Autopsy
Authors: C. Gaze David
Published: June 2023

The diagnosis of acute cardiac pathology is a clinical challenge in both the living and in the postmortem setting. Cardiac troponin (cTn) T and cardiac troponin I released from the contractile apparatus of cardiomyocytes into the circulation can be detected by sensitive and specific immunoassays and are the gold standard biochemical test for diagnosis of acute coronary syndromes (ACS). Recently with the advent of more sensitive detection methods, elevation in non-ACS has become apparent causing clinical confusion. In most cases, these elevations are related to subclinical cardiac damage and often confer poor prognosis in cTn-positive patients. Biomarkers of cardiomyocyte damage may be of value in routine hospital and medico-legal autopsy. A significant body of evidence has emerged since the late 1990s, assessing the clinical utility of cardiac troponin in biological fluids or in immunohistochemical staining of cardiac tissue to aid in the diagnosis of acute cardiac pathology when standard microscopic evidence is inconclusive. This chapter reviews the extensive literature on the subject and details the disparity between pericardial fluid and serum for the use of cTn in the postmortem setting.

Chloroplast engineering has matured considerably in recent years. It is emerging as a promising tool to address the challenges related to food security, drug production, and sustainable energy posed by an ever-growing world population. Chloroplasts have proven their potential by efficiently expressing transgenes, encapsulating recombinant proteins, and protecting them from cellular machinery, making it possible to obtain highly functional proteins. This quality has also been exploited by interfering RNA technology. In addition to the practical attributes offered by chloroplast transformation, such as the elimination of position effects, polycistronic expression, and massive protein production, the technique represents an advance in biosafety terms; however, even if its great biotechnological potential, crops that have efficiently transformed are still a proof of concept. Despite efforts, other essential crops have remained recalcitrant to chloroplast transformation, which has limited their expansion. In this chapter, we address the most recent advances in this area and the challenges that must be solved to extend the transformation to other crops and become the de facto tool in plant biotechnology.

Published: June 2023

As they are widely utilized in industries including the food packaging industry, indoor air quality testing, and real-time monitoring of man-made harmful gas emissions to successfully combat global warming, reliable and affordable gas sensors represent enormous market potential. For environmental monitoring, chemical safety regulation, and many industrial applications, the detection of carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), and methane (CH4) gases is essential. To reliably and quantitatively detect these gases, much-improved materials and methods that are adaptable to various environmental factors are needed using low-cost fabrication techniques such as sol-gel. The advantages of employing metal oxide nanomaterials-based chemoresistive for creating high-performance gas sensors are shown by key metrics such as selectivity, sensitivity, reaction time, and detection. The primary sensing methods are also grouped and thoroughly covered. In light of the current constraints, anticipated future developments in the field of sol-gel nanomaterial-based chemoresistive gas sensors are also highlighted.

Data were analyzed using SPSS software using descriptive statistics, independent sample t-test, and the chi-square test. Results: Auditory hallucinations (41.4%) and visual hallucinations (26.8%) were the most participants' common types of hallucinations. Persecution delusion (31.3%), grandeur delusion (17.7%), and reference delusion (16.7%) were the most common types of delusions reported. There were significant differences between the methamphetamine psychosis and non-psychosis groups regarding the rate, duration, and age of onset of methamphetamine use, as well as the prevalence of psychiatric diseases, suicide attempts, non-suicidal self-injury, and history of intoxication. Conclusions: The early detection of psychosis symptoms in methamphetamine users through follow-up reviews can prevent the occurrence of more destructive individual and social complications caused by these experiences. It is essential to consider all types of hallucinations and delusions to implement timely preventive actions for individuals with methamphetamine dependence.

Background: During the COVID-19 pandemic, educational programs have increasingly relied on virtual methods. Objectives: In this study, we compared the effects of in-person and virtual electroencephalography (EEG) training on the knowledge of pediatric and adult neurology residents. Methods: The study participants consisted of 30 pediatric and adult neurology residents who were recruited nationwide via a virtual network. They were randomly divided into two groups for in-person and virtual education, respectively. Prior to the first workshop session, participants completed a pre-test comprising 19 knowledge-related questions. Two interactive training sessions focusing on benign variants in EEG were conducted, including two in-person workshops for eight residents and two online workshops for 22 residents. Each session lasted one hour, with one held every two weeks. After the second session, participants were asked to complete a post-test consisting of 24 questions (identical to the pre-test) and five workshop satisfaction-related questions. Results: Overall, the mean exam score after both the in-person and virtual workshops was significantly higher than the pretest score across all educational levels. The mean score differences in knowledge between the in-person and virtual groups after the workshop were similar, with no statistically significant difference. Approximately 90% of the participants believed that the workshop would be beneficial for their daily practice. Conclusions: Given the absence of a significant difference between in-person and virtual training methods in improving participants' knowledge and satisfaction with both approaches, we recommend integrating virtual EEG training into the educational protocol for pediatric and adult neurology residents. Nonetheless, larger sample size studies are required to further validate these findings.

Background: The stunting countermeasures is one of the agendas in SDGs. The strategic and appropriate attempts could be planned based on the distribution of stunting and the influencing factors using a region-based data approach in accordance with the critical steps within the 2018 Global Nutrition Report.

Objective: The purpose of this study was to determine the spatial autocorrelation of stunting on children under five between districts/cities in Indonesia 2019.

Method: This research is an ecological study using a spatial approach. The data used was secondary data obtained from the study of Nutritional Status of children in 2019, with the unit of analysis for all districts/cities in Indonesia. The study was tested using the analysis of Global Moran’s I and Local Indicators of Spatial Association (LISA).

Result: The result of the analysis showed that stunting on children under five between districts/cities in Indonesia has a spatial autocorrelation with a clustered pattern (I=0.347).

Conclusion: Areas with high-high stunting patterns need to be set as priority areas for stunting reduction interventions. In addition, the formation of a Stunting Reduction Acceleration Team in these areas needs to be monitored thoroughly.

Latar belakang: Anemia masih menjadi masalah kesehatan masyarakat dunia dengan sasaran tertinggi adalah remaja putri dan wanita usia subur (WUS). Anemia juga menjadi kejadian paling sering dialami oleh remaja putri dikarenakan remaja putri mengalami menstruasi setiap bulannya. Anemia mengakibatkan terganggunya kualitas produktivitas pada remaja putri. Sehingga diperlukan suatu perilaku pencegahan anemia yaitu perilaku konsumsi tablet tambah darah (TTD) serta pola makan gizi seimbang.

Tujuan: Penelitian ini bertujuan untuk mengetahui gambaran perilaku mahasiswi kesehatan masyarakat dalam mengkonsumsi TTD dan pola makan gizi seimbang

Metode: Jenis penelitian ini adalah metode kualitatif dengan pendekatan deskriptif. Informan ditentukan secara purposive sampling, dengan karakteristik informan utama adalah mahasiswi kesehatan masyarakat Stikes Raflesia, dan informan kunci yaitu teman sebaya serta dosen yang mengajar di Stikes Raflesia. Metode pengumpulan data dilakukan dengan cara FGD (Focus Group Discussion), Wawancara Mendalam dan Observasi. Analisis data dilakukan dengan cara reduksi data, penyajian data, dan penarikan kesimpulan, untuk uji validitas data dilakukan dengan menggunakan triangulasi sumber dan metode.

Hasil: Faktor predisposisi yang selaras dengan rendahnya perilaku (mengkonsumsi TTD dan pola makan) informan dalam mencegah anemia saat menstruasi yaitu rendahnya pengetahuan informan terkait penyebab dan dampak anemia, tidak adanya dukungan baik dari keluarga maupun teman sebaya menjadi penyebab kurangnya upaya pencegahan pada informan.

Kesimpulan: Masih rendahnya perilaku konsumsi TTD dan pola seimbang pada mahasiswa sebagai upaya pencegahan terjadinya anemia

Background: Breastfeeding mothers have the opportunity to vaccinate, to protect against Covid-19 infection. Sociodemographic factors, health status, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and health motivation are important in making decisions to vaccinate for breastfeeding mothers.

Objective: This study aims to determine the association between sociodemographic characteristics, health status, perceptions of Health Belief Model (HBM) on vaccination decisions for breastfeeding mothers in the Tangerang area. 

Methods: An analytical design with a cross sectional approach and a total sample of 123 respondents were used in this study in the Tangerang area. 

Results: Except for the level of education of breastfeeding mothers, sociodemographic and health status factors are not associated with the decision making of Covid-19 vaccination. Based on the analysis of HBM perceptions on the perceived severity, perceived benefits, perceived barriers, cues to action and health motivation have a relationship with decision-making about Covid-19 vaccination in breastfeeding mothers.

Conclusions: In the HBM perception assessment there is a relationship between perceived severity, perceived benefits, cues to act, and health motivation with Covid-19 vaccination decision making. Likewise with negative perceptions have nothing to do with vaccine decision making, which is a strong predictor of getting the Covid-19 vaccine.

Preliminary investigation of a CFD-assisted virtual reality experience in engineering education
Authors: Solmaz Serkan , Kester Liesbeth , Van Gerven Tom
Published: June 2023

Virtual reality has become a significant asset to diversify tools in the support of engineering education and training. The cognitive and behavioral advantages of virtual reality (VR) can help lecturers reduce entry barriers to concepts that students struggle with. Computational fluid dynamics (CFD) simulations are imperative tools intensively utilized in the design and analysis of chemical engineering problems. Although CFD simulation tools can be directly applied in engineering education, they bring several challenges in the implementation and operation for both students and lecturers. In this study, to tackle these challenges, we developed the “Virtual Garage” as a taskcentered educational VR application with CFD simulations. The Virtual Garage is composed of a holistic immersive experience to educate students through a real-life engineering problem solved with CFD simulation data using a VR headset. The prototype is tested by graduate students (n=24). Participants assessed usability, user experience, task load and cybersickness via standard questionnaires together with self-reported questions and a semi-structured interview. Preliminary results reflect that the Virtual Garage is well-received by participants. We identify features that can further enhance the usability and user experience.
