On Physical Layer Design for Smart Cities
Authors: Kumar Ray Jayanta , Bera Rabindranath , Sil Sanjib , Alfred Quazi Mohmmad
Published: September 2023

In the future, the real world will convert to a smart world around 2025. One
could predict that there will be a changeover from 4G LTE to 5G NR. In pandemic
conditions, 4G LTE has been found to provide good online support, such as accessing
the Internet for education, administration, banking, official works, etc., anywhere in the
real world. But there are some limitations, such as operating machines in industries,
and driving vehicles on the road with the help of the Internet. These facilities will be
provided by 5G NR as there is a large difference between 4G LTE and 5G NR. In 4G
LTE, only Mobile Broad Band (MBB) is present, but in 5G NR, there are three terms,
i.e., Enhanced Mobile BroadBand (eMBB), Ultra-Reliable and Low Latency
Communication (URLLC) and massive Machine Type Communication (mMTC). As a
result, the city will convert into a smart city. It is possible by applying intelligence in
various technologies. Applying intelligence will lead to the improvement of smartness
in the environment, mobility, building, home, administration, health, education, etc.
The smartness of the item includes the utilization of the Internet in various devices,
which means the Internet of Things (IoT). In previous times, humans communicate
with humans, but in IoT, a human will communicate with the device. In the future, it
will be realized using NXP Semiconductors. NXP semiconductors manufactured
various chips, which should be beneficial for the formation of smart cities. In the near
future, facilities will be increased in a more massive manner than the present time. By
2030, the goal will have been fully attained, and IoT will have evolved into the Internet
of Everything (IoE), meaning that everything will be made possible by the Internet.
Device-to-device communication will be a possibility in IoE side-by-side. This outlines
how 5G to 6G will change.
Implementation of Smartphone-based Indoor Positioning Application Using Trilateration
Authors: Paul Saptarshi
Published: September 2023

Positioning applications using GPS, A-GPS, and other technologies are now
commonly found in most held hand smart devices. The advents in applications/tools
such as Google Maps have made outdoor positioning and guidance much easier.
Compared to outdoor positioning, Indoor positioning has always been more
challenging. Indoor positioning faces an uphill task of proper Position fixing due to an
array of issues that are otherwise absent in the outdoor environment. In this chapter,
through trilateration, we have devised an application that takes the help of Wi-Fi
signals and does Position fixing in an indoor environment. Indoor localization and
positioning is still a challenging topic in Wireless Sensor Networks, and also it is vital
because of its effects on monitoring, power consumption, etc., for our work distance
calculation of an object using the proposed path loss model, and Trilateration method is
implemented to calculate the unknown Position of a device under the environment. It
collects all the Wi-Fi signals and finds the exact matches with the database to calculate
the user's actual Position on the map. It reduces the complexity of computing the
distance of different access points from the user and reduces error. The tool was found
to be quite promising in detecting the Position of the host device. Future work that can
be extended from this work can include work with a path loss model, Multi-Sensor
Fusion, to the inclusion of pattern recognition.
Tools and Techniques to Analyse Microplastic Pollution in Aquatic and Terrestrial Ecosystems
Authors: Priyadarshi Gautam , Prajapati Sagar , Trivedi Mrugesh
Published: September 2023

The estimation of microplastic pollution in the terrestrial and aquatic
ecosystem is carried out by quantification and identification of the contaminated
environment. Microplastic estimation consists of various steps such as sampling,
visualization and quantification. Generally, the planktonic net, bongo net, manta net,
and neuston net have been used for water sampling. While, grab samplers, tweezers,
tablespoons, trowels, shovels, spatulas, or hand picking methods have been used for soil
and sediment sampling. The biological sample from the study sites comprises the direct
collection of the whole organism or its colony as a sampling unit. However all samples
are required to be processed further to extract the microplastic using techniques such as
filtration, density extraction, digestion, and magnetic & electrostatic extraction. The
digestion method is used for direct characterization such as thermal gravimetric
analysis. The identification of microplastic is based on microscopic images which
provide the shape, size, colour, and texture of the microplastic surface. Visual
identification using microscopes is time-consuming and susceptible to human error as
well as a risk of misidentification, which leads to underestimation or overestimation of
microplastic pollution. Spectroscopic methods such as ATR-FTIR, µ-FTIR and Raman
spectroscopy provide identification and quantification of synthetic polymer. Advance
combined analytical techniques have been reported during the last few years such as
portable micro-Raman, SEM-FTIR, Pyr-GC-MS, TGA-DSC, and PEE. Priority and
care are essential concerning the sampling, storage and handling microplastic
samples for the QA/QC for accurate analysis. The present chapter aims to provide a
comprehensive overview of the current knowledge of tools and techniques used for
microplastic inquiries from an environmental sample.
Bioplastic as an Alternative to Microplastic
Authors: Kumar Sachan Rohan Samir , Kaur Somal Manpreet , Bala Ritu , Khushboo Bentham Science Publisher , Kumar Mukesh , Devgon Inderpal , Karnwal Arun
Published: September 2023

Microplastics pose an imminent risk to the marine environment, biota, and
ecosystem. Their consumption threatens organisms because of the material's ability to
absorb and concentrate environmental contaminants in oceans and then transfer them
through food chains. Microplastic may harm soil biota, such as earthworms, and can
alter soil biophysical parameters, such as soil bulk density, aggregation, and water-holding capacity. To find alternatives to microplastics, scientists have developed
biodegradable plastics that can be discarded in the environment and broken down
quickly by the enzymatic activity of micro-organisms. Bioplastics are made from
biological or renewable components. The bioplastic produced from potato peels, corn,
sugarcane, wheat, rice, banana peels, and other natural materials is eco-friendly and
biodegradable. Bioplastic is also known as Low-carbon plastic. The use of low-carbon
plastic aids in the regulation of global temperature rise. It is used to make toys, home
interiors, shopping bags, bottles, labels, trash bags, and packaging materials. It has
wide applications for bone nails and tissue scaffolds in the medical industry. Its
development also faces other obstacles, including price difficulties, technical
improvements, and waste collection and treatment. Synthesis and characterization
methods will help overcome these obstacles. The present chapter will focus on
bioplastic and its types, the synthesis of bioplastic, the difference between microplastic
and bioplastic, and bioplastic as an alternative approach.

Artificial intelligence (AI) has gained enormous usage in business in recent
years. Still, in regard to measuring business ethics and morality, otherwise called
corporate social responsibility, the use of Artificial Intelligence is limited to a greater
extent. In this regard, the purpose of the study is to conceptually formulate the
implementation of AI in CSR programs. For gathering data, the study utilised a
structured questionnaire. Employers from a range of governmental and commercial
organisations provided the primary data for the study. Using AMOS 21's Structural
Equation Modelling (SEM) and SPSS 21, the projected model was empirically tested.
The Research concludes that AI can strengthen effective CSR practices. The research
also uses SEM to establish a cause-and-effect connection between the research
variables.
Perspectives on Augmented and Virtual Reality (AVR) in Education: Current Technologies and the Potential for Education
Authors: Sheela S. Christina , Selvalakshmi V. , Doss S.P.S. Arul
Published: September 2023

By combining information in the form of image alternatives with a software
programme that stores knowledge on real images, augmented and virtual reality (AVR)
technologies aid in the explanation of concepts. This methodology is developed to
improve educational learning through two-dimensional media in education. In bloom
taxonomy approach to teaching, integrating AR technology with academic content
results in a new kind of automated application that serves to reinforce the usefulness of
teaching-learning for learners in real-world situations. The learning outcome, which
includes knowledge level and performance engagement, has a significant impact on all
phases of higher education, from course planning to student evaluation and grading.
AVR is a novel technique that combines elements of omnipresent computing, tangible
computing, and social computing. This mode offers different affordances, combining
the physical and virtual worlds, with continuous and implicit purposes of reading and
interactivity. Digital resources are high-potential educational technology that enhances
learning by supporting the learning environment through numerous e-resources. The
various universities and Technical and Vocational Education Training (TVET)
institutions give students an opportunity to complete an experiential learning
component in their studies in order to complete their qualifications with the help of
AVR implementation. This chapter provides an introduction to Augmented and Virtual
reality (AVR) technology, the current status in education from different viewpoints,
key technologies, and strategies mentioned in the context of higher educational
learning output of students through these applications.
A New Approach to Crime Scene Management: AR-VR Applications in Forensic Science
Authors: Sharma Vinny , Kumar Rajeev , Bhati Kajol , Saini Aditya , Singh Shyam Narayan Narayan
Published: September 2023

The crime scene, a place where a crime has been or is suspected to have
occurred or where the evidence related to a crime was found, is a vital part of the
investigation as it contains all the major information about a crime. A keen eye for the
crime scene can determine the possible Modus Operandi of a crime and establish
Corpus Delicti in a court of law. As per Indian law, we are allowed to visit a crime
scene once only and if we want to visit again, we have to take permission but it is of no
use. During a revisit to a crime scene, the chance or probability of finding any evidence is
nearly 0%. Documenting a crime thus became a very crucial step. By using ordinary
methods for documenting the crime scene we cannot give a visual or walk to the actual
crime scene. It’s just a physical view of the documents. It is, therefore, critical to
visually capture the crime scene and any potential evidence to aid the investigation.
The current demand is for Augmented Reality and Virtual Reality. Virtual Reality is a
wholly virtual view of the scenario, whereas Augmented Reality reflects a real-world
context. VR is a type of advanced user interface that comprises a real-time simulation
of a real-world environment with which the user interacts through numerous sensory
channels: sight, hearing, touch, smell, and taste. The 3D reconstruction and
visualization of crime situations such as criminal assaults, traffic accidents, and
homicides is a new method of criminal investigation that has the potential to improve
efficacy. To produce an accurate and immersive virtual environment, modern 3D
recording and processing methods, such as AR and VR, are used. Immersion in a
virtual environment, on the other hand, allows for various points of view.
Lo-Fi Femme: The Messy Hypermediacy of Aspirational Femininity in Melisa Liebenthal’s "Las lindas" (2016)
Authors: Castillo Anna
Published: September 2023

This article merges discursive-based scholarship with a phenomenological approach to analyze the media convergence in Melisa Liebenthal’s Las lindas (2016), a personal documentary which explores thresholds of femininity through liminal life stages of girlhood, adolescence, and womanhood. Lo-fi aesthetics and post-production techniques reduce the primacy of the visual logic of feminine allure, highlighting the physical exchange of media and heightening audience awareness of cultural practices that reinforce standards of femininity. The film thus filters the reality of femininity in such a way as to make it unsteady, incomplete, and never quite in focus, forestalling any notion of its completion or attainability.
Intermedialidad, imaginación creadora y experiencia vital en "La afinadora de árboles" (2019), de Natalia Smirnoff
Authors: Valcheff García Fernando
Published: September 2023

La afinadora de árboles (2019), largometraje escrito y dirigido por la cineasta argentina Natalia Smirnoff, narra la historia de Clara Mains (Paola Barrientos), una autora de literatura infantil que, luego de recibir un prestigioso premio internacional, intenta superar su bloqueo creativo reconectando con personas del pasado que la inspiran a esbozar un nuevo futuro. El presente trabajo explora la película de Smirnoff desde una perspectiva intermedial, abordando la articulación de la práctica creadora y trayectoria vital de la protagonista mediante un análisis del diálogo entre lenguajes, códigos y medios artísticos, y su vínculo con cruces y tensiones entre juventud y madurez, espacios privados y públicos, y producción individual y colectiva en el devenir de la cinta.  
La afinadora de árboles [The Tree Tuner] (2019), written and directed by the Argentine filmmaker Natalia Smirnoff, depicts the story of Clara Mains (Paola Barrientos), a children’s literature author who, after receiving a prestigious international award, tries to overcome a creative block reconnecting with people from her past who inspire her to imagine a new future. This paper explores Smirnoff’s film from an intermedial perspective, addressing the articulation of the protagonist’s creative practice and life trajectory through an analysis of the dialogue between artistic languages, codes and media, and their links to the intersecting themes of–and tensions between–youth and maturity, private and public spaces, and individual and collective production.

Sepulchral Intermediality in Paula Markovitch’s "Armando y Genoveva" (2013)
Authors: Selimović Inela
Published: September 2023

This article explores Paula Markovitch’s intermedial reconstruction of her parents’ public (in)visibility in Armando y Genoveva (2013). Markovitch’s intermedial choices—particularly those moments in the documentary when recorded voices are superimposed on the scenes that brim with her parents’ artwork—contain a focused political significance related to her parents’ artistic conviviality and existential fragility. As the recorded audio footage and the filmed artwork further intersect with the filmmaker’s provocative touch and retrospective voice-over, the parents’ key identity traits as well as their uncertain sense of social belonging take center stage. Such intermedial interactions also begin a process of immortalizing the parents’ unbroken commitment to artistic expression despite their life-long isolation in response to Argentina’s political violence (1976–1983).

Authors: Lekule B. R. , Nicodemas D.
Published: September 2023

The study aims to assess the effects of water, sanitation and hygiene practices on the nutrition status of children under five years in the Songwe region of Tanzania since malnutrition is still a big challenge in developing countries, particularly the Southern Highlands Zone which needs integrated measures to be addressed. Cross-sectional studies involving 110 children aged 0-59 months were assessed for Weight-for-Age, Height-for-Age and Weight-for-Height involving a structured questionnaire. Results showed that 47.27% were stunted, 27.27% were underweight while 16.36% were wasted and 53.63% of respondents did not participate in any community program. The study also revealed that 35.45% had pit latrines, 44.54% used communal pit latrines, 13.63% had flush toilet types and 6.36% did not have any kind of toilet. Lack of proper latrine increases the chances of getting infections such as worm infestation. 37.27% of respondents still use unimproved sources (River water, dams, ponds) and 65.45% of respondents use untreated water for drinking, cooking, and food preparation activities which increases disease incidences and infections. The presence of poor nutrition status of children under age five in the study sample was caused by poor childcare practices. These findings alert the Government starting from the local government level to use nutrition stakeholders to effectively influence mothers/caregivers to make healthy dietary practices.

SOME CARBONYL COMPOUNDS, FREE FATTY ACID COMPOSITIONS AND TOCOPHEROL CONTENTS OF KAYMAK (CLOTTED CREAM) PRODUCED FROM COW, SHEEP AND GOAT MILK
Authors: YILMAZER Mustafa , ÖZAYDIN Ayşe Gül , ALBAY Zehra , ŞİMŞEK Bedia
Published: September 2023

The aim of this study is to determine the effect of cow, goat and sheep milk used in traditional clotted cream production on some properties of clotted cream. The produced clotted cream was stored during 7 days. Some chemical analyses of the clotted cream, free fatty acid composition and tocopherol contents using gas chromatography (GC) and high-performance liquid cromatography (HPLC) were determined. Saturated fatty acids were found to be the highest in sheep's clotted cream and the lowest in goat's clotted cream. Monounsaturated fatty acids were found to be higher in clotted cream produced from goat's milk. Eicosapentaenoic Acid (EPA) and docosanhexaenoic acid (DHA) and δ-tocopherol were determined only in clotted cream produced from sheep milk. The content of α-tocopherol in sheep's clotted cream and β-tocopherol in cow's clotted cream is higher than in the other clotted cream. 2-Methylbutyraldehyde was identified as the most important carbonyl component in all samples. Although all three clotted creams were quite similar in appearance and some chemical properties, it was determined that they contain significant differences in terms of carbonyl compounds, fatty acid profiles and tocopherol contents.
Acceptability of the eHealth Intervention Sustainable Worker Digital Support for Persons With Chronic Pain and Their Employers (SWEPPE): Questionnaire and Interview Study
Authors: Svanholm Frida , Turesson Christina , Löfgren Monika , Björk Mathilda
Published: September 2023

Background

Sick leave and decreased ability to work are the consequences of chronic pain. Interdisciplinary pain rehabilitation programs (IPRPs) aim to improve health-related quality of life and participation in work activities, although implementing rehabilitation strategies at work after IPRPs can be difficult. Employers’ knowledge about pain and the role of rehabilitation needs to be strengthened. The self-management of chronic pain can be improved through eHealth interventions. However, these interventions do not involve communicating with employers to improve work participation. To address this deficiency, a new eHealth intervention, Sustainable Worker Digital Support for Persons with Chronic Pain and Their Employers (SWEPPE), was developed.

Objective

This study aimed to describe the acceptability of SWEPPE after IPRPs from the perspective of patients with chronic pain and their employers.

Methods

This study included 11 patients and 4 employers who were recruited to test SWEPPE in daily life for 3 months after IPRPs. Data were collected using individual interviews at the end of the 3-month test period and questionnaires, which were completed when SWEPPE was introduced (questionnaire 1) and at a 3-month follow-up (questionnaire 2). Data were also collected on how often SWEPPE was used. Qualitative data were analyzed through a qualitative content analysis using an abductive approach. The framework used for the deductive approach was the theoretical framework of acceptability. Quantitative data were analyzed through descriptive statistics and the differences between the responses to questionnaires 1 and questionnaire 2 using the Wilcoxon signed rank test.

Results

Both patients and employers reported that SWEPPE increased their knowledge and understanding of how to improve work participation and helped them identify goals, barriers, and strategies for return to work. In addition, participants noted that SWEPPE improved employer-employee communication and collaboration. However, experiences and ratings varied among participants and the different SWEPPE modules. The acceptability of SWEPPE was lower in patients who experienced significant pain and fatigue. A high degree of flexibility and choice of ratings in SWEPPE were generally described as helpful.

Conclusions

This study shows promising results on the user acceptability of SWEPPE from both patient and employer perspectives. However, the variations among patients and modules indicate a need for further testing and research to refine the content and identify the group of patients who will best benefit from SWEPPE.
Internet Use as a Moderator of the Relationship Between Personal Resources and Stress in Older Adults: Cross-Sectional Study (Preprint)
Authors: Roquet Angélique , Martinelli Paolo , Lampraki Charikleia , Jopp Daniela S
Published: September 2023

BACKGROUND

Internet use has dramatically increased worldwide, with over two-thirds of the world’s population using it, including the older adult population. Technical resources such as internet use have been shown to influence psychological processes such as stress positively. Following the Conservation of Resources theory by Hobfoll, stress experience largely depends on individuals’ personal resources and the changes in these resources. While personal resource loss has been shown to lead to stress, we know little regarding the role that technical resources may play on the relationship between personal resources and stress.

OBJECTIVE

This study aims to investigate the moderating effect of technical resources (internet use) on the relationship between personal resources and stress in younger and older adults.

METHODS

A total of 275 younger adults (aged 18 to 30 years) and 224 older adults (aged ≥65 years) indicated their levels of stress; change in personal resources (ie, cognitive, social, and self-efficacy resource loss and gain); and internet use. Variance analyses, multiple regression, and moderation analyses were performed to investigate the correlates of stress.

RESULTS

Results showed that older adults, despite experiencing higher levels of resource loss (questionnaire scores: 1.82 vs 1.54; P<.001) and less resource gain (questionnaire scores: 1.82 vs 2.31; P<.001), were less stressed than younger adults (questionnaire scores: 1.99 vs 2.47; P<.001). We observed that the relationship among resource loss, resource gain, and stress in older adults was moderated by their level of internet use (β=.09; P=.05). Specifically, older adults who used the internet more frequently were less stressed when they experienced high levels of both loss and gain compared to their counterparts who used internet the less in the same conditions. Furthermore, older adults with low resource gain and high resource loss expressed less stress when they used the internet more often compared to those with low internet use.

CONCLUSIONS

These findings highlight the importance of internet use in mitigating stress among older adults experiencing resource loss and gain, emphasizing the potential of digital interventions to promote mental health in this population.
Development of a Risk Score to Aid in the Diagnosis of Infections after Spinal Cord Injury: Protocol for A Retrospective Cohort Study (Preprint)
Authors: Skelton Felicia , Grigoryan Larissa , Pan Joann , Trautner Barbara
Published: September 2023

BACKGROUND

Background: Spinal cord injury (SCI) patients who develop urinary tract infection (UTI) present differently in SCI patients than non-SCI population. UTIs can cause loss of quality of life, and even lead to life-threatening complications including urosepsis. One of the biggest challenges in SCI management is distinguishing symptomatic urinary tract infection (UTI) from asymptomatic bacteriuria (ASB), which is also high in SCI patients, and there is a lack of standardization.

OBJECTIVE

Objective: This study aims to:
#1) Create baseline physiological vital signs and lab values for SCI patients and controls.
#2) Determine positive predictive values of physiologic measures for UTI to inform a risk score in SCI patients, allowing improvement of UTI diagnosis accuracy in SCI patients and prevention of overuse of antibiotics.

METHODS

Methods:
#1) This retrospective cohort data is collected from national Veterans Health Administration data and used to establish physiologic baseline for vital sign and lab measurements after SCI.
#2) A validated case classification algorithm will help classify ASB, UTI or indeterminate and determine positive predictive values for vital sign and lab thresholds for UTI after SCI.

RESULTS

Results:
Currently our anticipated results include SCI patients having lower blood pressure, temperature, hemoglobin, and higher white blood cell count versus control. However, mean serum white blood count, glucose, and urine white blood cells are expected to be higher in the SCI cases as compared to non-SCI controls. Additionally, vital signs and lab derangements will likely have high positive predictive value for UTI.

CONCLUSIONS

Conclusions:
In order to figure out differences in vital signs between SCI patients and controls, we aim to establish a baseline physiology vitals in SCI patients and then also calculate vital signs and lab thresholds for UTI for SCI patients. It is vital that we establish the thresholds for UTI diagnosis in SCI patients as they differ from controls and UTIs can have severe complications in SCI patients.

Authors: Awindaogo Felix , Acheamfour-Akowuah Emmanuel , Doku Alfred , Kokuro Collins , Agyekum Francis , Owusu Isaac Kofi
Published: September 2023

BACKGROUND

Heart failure (HF) is a leading cause of morbidity and mortality globally, with a high disease burden. The prevalence of HF in Ghana is increasing rapidly, but epidemiological profiles, treatment patterns, and survival data are scarce. The national capacity to diagnose and manage HF appropriately is also limited. To address the growing epidemic of HF, it is crucial to recognize the epidemiological characteristics and medium-term outcomes of HF in Ghana and improve the capability to identify and manage HF promptly and effectively at all levels of care.

OBJECTIVE

This study aims to determine the epidemiological characteristics and medium-term HF outcomes in Ghana.

METHODS

We conducted a prospective, multicenter, multilevel cross-sectional observational study of patients with HF from January to December 2023. Approximately 5000 patients presenting with HF to 9 hospitals, including teaching, regional, and municipal hospitals, will be recruited and evaluated according to a standardized protocol, including the use of an echocardiogram and an N-terminal pro-brain natriuretic peptide (NT-proBNP) test. Guideline-directed medical treatment of HF will be initiated for 6 months, and the medium-term outcomes of interventions, including rehospitalization and mortality, will be assessed. Patient data will be collated into a HF registry for continuous assessment and monitoring.

RESULTS

This intervention will generate the necessary information on the etiology of HF, clinical presentations, the diagnostic yield of various tools, and management outcomes. In addition, it will build the necessary capacity and support for HF management in Ghana. As of July 30, 2023, the training and onboarding of all 9 centers had been completed. Preliminary analyses will be conducted by the end of the second quarter of 2024, and results are expected to be publicly available by the middle of 2024.

CONCLUSIONS

This study will provide the necessary data on HF, which will inform decisions on the prevention and management of HF and form the basis for future research.

Due to its potential to completely change how medical services are delivered, cloud computing has attracted a lot of attention in the healthcare industry. This essay explores the enormous effects of cloud computing on healthcare systems, looking at its uses, benefits, difficulties, and potential. Beginning with a discussion of cloud computing's core ideas and its many models, including Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS), in the context of healthcare. It looks into the processes through which cloud computing improves patient outcomes and simplifies healthcare operations. The paper includes a thorough examination of its applications, which cover telemedicine, remote patient monitoring, administration of Electronic Health Records (EHR), and medical imaging. The paper also discusses the benefits of cloud adoption, such as scalability, affordability, collaborative care, and disaster recovery. On the other hand, it covers important issues like data security, privacy worries, and regulatory compliance, concentrating particularly on legal frameworks like HIPAA. The concrete advantages and possible difficulties of cloud adoption are shown in case studies of healthcare organisations that have used them. The report also looks ahead to the use of cloud computing in healthcare, speculating on trends, advances, and moral ramifications. In conclusion, this study demonstrates how cloud computing is revolutionising healthcare delivery by providing effective answers to age-old problems. The study promotes a thorough knowledge of the dynamic interaction between cloud computing and healthcare by exploring real-world examples and theoretical foundations, stressing its transformational potential while admitting the complicated concerns inherent in its implementation.

BACKGROUND

The COVID-19 global pandemic has contributed to increases in mental health issues such as depression and anxiety due to the increase of social isolation, uncertainty, and misinformation while at the same time making it harder to access mental health resources. In response to the pandemic, four counties/cities in California began offering a free mindfulness meditation app known as Headspace as a mental health resource for their communities.

OBJECTIVE

This study aimed to capture characteristics of people who decided to use, stop using, or not use Headspace within the context of a COVID-19 response program launched in April 2020 which offered Headspace licenses for free to community members.

METHODS

Participants (n = 2,725) completed a 20-minute online survey between July 1, 2021 and October 21, 2022. All participants who had signed up for Headspace through the program (N = 92,311) were sent an email inviting them to complete the survey, which was voluntary and unpaid. Logistic regression models were used to examine relationships between continued use of Headspace and the prevalence of mental health problems, mental healthcare utilization, frequency of Headspace use, user experience with Headspace, and mental health stigma.

RESULTS

76% of respondents were still using Headspace at the time of completing the survey. People who were still using Headspace were more likely to experience mental health challenges and distress and reporter greater use of other digital mental health resources (i.e. online tools and connecting with people online) than people who were not using Headspace. Additionally, people who used the app on a more frequent basis were more likely to continue using it, and current Headspace users rated the app higher on user experience compared to past users. The most common reasons for abandoning Headspace were that people were already using other strategies to support their mental health (35%), no longer needed Headspace (13%), and/or did not think Headspace would be useful (8%).

CONCLUSIONS

We discuss potential implications of our findings for offering and using apps such as Headspace as a mental health resource, along with factors that influence engagement with this app.
Gender and satisfaction of basic psychological needs: an exploratory study of pottery crafts in Latin America
Authors: Sánchez-Medina Patricia S. , Díaz-Pichardo René , Guevara-Flores Joseph S.
Published: September 2023

Purpose: This paper analyzes the relationship between gender and the satisfaction of basic psychological needs in the artisanal pottery sector in Latin America.
Methodological design: We surveyed 195 owners/managers of small family businesses operating in artisanal communities in three Latin American countries: Mexico, Honduras, and Colombia. We used structural equation modeling to offer evidence of factorial invariance of the measurement instrument across genders.
Results: We found that women artisans seem to be more satisfied than men in meeting their need for autonomy and competence, revealing an important benefit of artisanal activity. No significant difference was found in relation to the fulfillment of the need for relatedness.
Research limitations: The limitations of this research are derived from the sampling method, which was mainly driven by practical, financial, and logistical restrictions rather than by theoretical criteria. Nonresponse bias may have also affected our results.
Findings: It is important for the artisanal sector to find motivational factors that contribute to the continuity and development of the sector.

Unequal Clustering Methods in Wireless Sensor Networks
Authors: T Brindha. , Raju Mrs. M.
Published: September 2023

Abstract: Due to its many applications, WSN has become a crucial technology for ubiquitous living and is still being actively researched. An important design consideration for WSN is energy awareness. The most common energy-efficient strategy, clustering offers numerous advantages, such as improved energy efficiency, extended lifetime, enhanced scalability, and reduced latency. However, it can also introduce the issue of creating hot spots. Uneven clustering is suggested as a remedy. When there is unequal clustering, the base station (BS) distance directly affects how big the cluster is. We were motivated to conduct this analysis because there were no current, in-depth survey articles that used unequal clustering methodologies. This research provides a comprehensive examination of various unequal clustering methods, along with their objectives, characteristics, and more. Furthermore, classifications of unequal clustering approaches are established and compared based on various cluster features, Cluster Head (CH) properties, and the clustering method employed.
Stock Price Prediction using LSTM and KNN Algorithms
Authors: Kowti Vineet G
Published: September 2023

Abstract: The aim of this study is to enhance and evaluate the performance of Long Short-Term Memory (LSTM) and K Nearest Neighbor (KNN) algorithms when used to forecast stock prices. In this study, previously recorded data on price as well as other crucial factors like transaction volume and market sentiment must be collected from reliable sources. The information gathered is then cleaned, preprocessed and refined in order to make sure it is compatible with the training model. Then, we developed two forecasting models, one using (LSTM) and (KNN). LSTM models are trained using historical data, and the performance of these models is evaluated using a variety of metrics, such as mean squared error and mean error. The performance evaluation and comparison of the above two models are conducted saying LSTM model outperforms the KNN model in accuracy.

Fascismo de cor: inferências sobre um debate na perspectiva da semiose social
Authors: Ferreira Jairo
Published: September 2023

In the context of the debate between the perspective of structural racism (Almeida, 2019) and the fascism of color (Sodré, 2023)), we develop, in this article, several inferences about fascism from the perspective of mediatization. At first, we compare the two contributions, in an approach that accentuates the contradictions, without necessarily antagonizing them. In the second part, we present the matrix we developed on mediatization as a social semiosis. In the third section, we present conclusive inferences to think about the relationships between fascism, racism and mediatization.
