Heart rate variability biofeedback intervention programme to improve attention in primary schools
Authors: Ruiz Ainara Aranberri , Seco Malen Migueles
Published: July 2024

The importance of attentional capacity for academic performance is highlighted by the increasing demands placed on students during primary school. Between the ages of 6 and 12, there is an evolutionary improvement in attentional capacity and the school environment is shown to be an appropriate setting in which to develop programmes to improve attention. Heart rate variability is an appropriate indicator of attentional capacity. For all these reasons, a heart rate variability biofeedback intervention focused on breathing was developed and implemented to improve attention. The intervention consists of two phases. In the first phase, the teachers of the school are trained to develop the intervention. In the second phase, the students receive 5 individual sessions from their teachers. In each individual session, they learn to breathe in a way that increases their heart rate variability. A total of 272 girls and 314 boys (N=586) aged 6-12 years participated in the programme. In order to study the impact on the three cycles of primary school, the attention of the control and experimental groups was assessed before and after the implementation of the programme. According to the data obtained, despite developmental improvements, the students who participated in the programme showed an increase in heart rate variability and an improvement in attentional capacity, with a greater impact on the first cycle of primary school. Our conclusion is to discuss the usefulness of heart rate variability biofeedback interventions in improving attention in primary school children and to present arguments for their use.
WITHDRAWN: Development of a Novel Hybrid Salp Swarm-Kepler Algorithm for Engineering Problems: Optimizing Microgrid Sizing with Integration of Photovoltaic, Wind, Battery, and Supercapacitor Systems
Authors: Güven Aykut Fatih
Published: July 2024

Economic growth accelerates, leading to an increasingly important need for efficient resource use in engineering design due to the resulting supply and demand imbalance. This study introduces an integrated hybrid application of the Salp Swarm Algorithm (SSA) and the Kepler Optimization Algorithm (KOA) to optimize engineering design problems. The integration of SSA’s mathematical modeling of salp movement and leader-follower dynamics, along with KOA's optimization mechanisms based on Kepler’s laws, provides significant advancements in avoiding local optimum traps and achieving balance in the search space. The hybrid SSAKOA algorithm is capable of quickly reaching optimal or near-optimal solutions to optimization problems while efficiently working across parameters. Experimental results show that SSAKOA outperforms other algorithms in terms of optimum performance, solution stability, and applicability, effectively reducing resource wastage in engineering designs. The optimization capability of the SSAKOA has been verified for 23 different function problems, revealing that SSAKOA offers higher convergence speed, precision, and robustness than other algorithms. Moreover, this algorithm has yielded the most optimal results compared to 12 different algorithms in sizing a microgrid consisting of grid-connected batteries, supercapacitors, wind turbines, and photovoltaic panel components, which poses a significant engineering challenge. This study demonstrates the effectiveness of the proposed algorithm by applying it to a hybrid renewable energy system on a Turkish university campus. The application reveals an annual cost of $572,369.93 and an energy cost of $0.23996/kWh, achieving a renewable energy fraction of 78.54%. This indicates that the system not only offers a cost-effective alternative to Turkey's conventional grid rate of $0.35/kWh but also underscores the algorithm’s potential in enhancing the economic and environmental sustainability of renewable energy projects. Such findings lay a foundational framework for future advancements in renewable energy applications.

This study investigates the incorporation of zinc oxide (ZnO) and ketoprofen (keto) into poly(lactic acid) (PLA) filaments to enhance their biocompatible. PLA is widely used in additive manufacturing, especially in biomedical applications, due to its biodegradability and biocompatibility. However, its interaction with biological tissues can be improved. ZnO was chosen for its wound-healing properties, while keto, a nonsteroidal anti-inflammatory drug, was selected to provide local anti-inflammatory effects. PLA filaments were prepared by incorporating ZnO and keto, followed by analyses of their mechanical, thermal, and biological properties. The results showed that the incorporation of ZnO and keto did not compromise the mechanical and thermal properties of the PLA filaments. Compared to pristine PLA, the composites presented a slight improvement in strength. The incorporation of ketoprofen in the composite increased its thermal stability compared to PLA-ZnO filament. Concerning the morphology, when ZnO and Keto were inserted, the scaffold acquired a more robust structure, with well-defined porosity. In vitro biocompatibility tests indicated that the modified filaments exhibited lower cellular toxicity and improved cell adhesion and proliferation compared to pure PLA. Antimicrobial tests demonstrated that the filaments containing ZnO, at the evaluated concentration, did not exhibit activity against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa, gram-positive and gram-negative bacteria. The combination of ZnO and ketoprofen in PLA filaments can enhance their biomedical applications, providing better biocompatibility without compromising the intrinsic characteristics of PLA. This work paves the way for the development of safer and more effective medical implants and devices.

Published: July 2024

Background: Fleas and ticks serve as vectors of multiple pathogens in the genera Rickettsia and Bartonellathat cause diseases in humans and other animals. Although human rickettsiosis and bartonellosis have been reported in all countries in Central America, limited research has been conducted to investigate the natural cycles of flea- and tick-borne rickettsiosis and bartonellosis, especially in Guatemala.
Methods: We evaluated dog parasites as sentinels for zoonotic disease risk in rural Guatemala by sampling ticks and fleas from dogs, which were then identified and individually screened for Rickettsia and Bartonella.
Results: A total of 77 households were surveyed and 80.52% of them had dogs. Overall, 133 dogs were examined for fleas and ticks, of which 68.42% had fleas and 35.34% had ticks. A total of 433 fleas and 181 ticks were collected from the infested dogs, with an additional 33 ticks collected from house walls. Three flea species were identified: Ctenocephalides felis (70%), Echidnophaga gallinacea(11.8%), and Pulex sp. (17.8%). Among the collected ticks, 97% were Rhipicephalus sanguineus with the rest being Amyblyomma cajennense, A. auricularium, and A. ovale. Rickettsia felis were detected in six C. felis, in one Pulex sp., and in two R. sanguineus, while Candidatus R. senegalensis was detected in one C. felis. Bartonella was detected only in fleas, including three Pulexsp. infected with B. vinsonii subsp. Berkhoffii, B. henselae, and Bartonella sp., respectively, and 11 C. felis infected with B. henselae.
Conclusions: This study reports Candidatus R. senegalensis and B. vinsonii subsp. Berkhoffiiin Guatemala for the first time, and indicates the potential risk of human and dog exposure to Rickettsia and Bartonella species. These results show that dogs provide critical information relevant to managing human potential exposure to flea- and tick-borne pathogens in rural Guatemala.

The great development in different technologies as Internet of Things (IoT) has changed the lifestyle of inhabitants. Therefore, the greater need for new technologies is also increased and new smart applications have emerged. The smart home (SH) is one of the most important and popular smart application giving the possibility to his users to control smart home devices. Unfortunately, this control is performed under insecure channel opening the door to many attacks. In this paper, we propose a new secure authentication and session-key agreement in a smart home environment. The proposed scheme combines a lightweight to mitigate the smart devices requirements and security to ensure reliable communication. To avoid the synchronization problem, our method uses local timestamp and increment number. The proposed scheme resists to several types of attacks and it is validated using Burrows-Abadi-Needham (BAN) logic and Automated Validation of Internet Security Protocols and Applications (AVISPA) tool.
A robust federated biased learning algorithm for time series forecasting
Authors: Song Mingli , Zhao Xinyu , Pedrycz Witold
Published: July 2024

The federated averaging algorithm (FedAvg) is extensively used for multi-sensor data modeling but often overlooks the unique characteristics of local models when privacy and data security are not considered. This study introduces a novel federated learning algorithm built upon the FedAvg framework, which emphasizes the specificity of each local model to optimize global knowledge aggregation. The algorithm's effectiveness is demonstrated through an air quality index prediction problem, showcasing superior prediction performance and robustness in noisy data scenarios. Additionally, the study delves into the reliability and robustness of the proposed approach, addressing the prevalent notion that centralized learning methods often surpass federated learning when data security is not a concern. Our experiments affirm the necessity and superiority of federated learning methods, even in the absence of privacy considerations, by effectively managing real-world noisy data.
C4D-YOLOv8: Improved YOLOv8 for Object Detection on Drone-captured Images
Authors: Zeng Weihui , Wu Pengcheng , Wang Junyan , Hu Gensheng , Zhao Jinling
Published: July 2024

Unmanned aerial vehicles (UAVs), as an emerging technology with vast application prospects, produce distinctive images due to factors, such as their shooting environment, altitude, and equipment. These UAV-captured images possess unique characteristics compared with traditional pictures, including high resolution, abundant presence of small objects, and object density. However, most existing object detection networks primarily focus on detecting large objects, resulting in limitations in terms of detecting small targets. The current detection networks frequently lose significant information whilst extracting features of small targets, resulting in a substantial decrease in detection accuracy. Accordingly, we have employed an improved version of YOLOv8 to address these issues, taking into consideration the aforementioned challenges,. We have devised a novel feature extraction module called C4, which aims to regain the crucial feature information of small targets that may have been overshadowed by the background. In contrast to the previous C2F or C3 modules, the C4 module incorporates a pathway with a larger convolutional kernel. Additionally, we have introduced a small target detection layer and an attention mechanism-based target detection head called ‘DyHead’ into the original yolov8s architecture. This approach has yielded a remarkable improvement in performance, achieving a mean average precision value of 45.8% on the VisDrone dataset, which represents a 4.9% accuracy enhancement compared with YOLOv8s (baseline).

The proviral factor NUP153 binds viral proteins and RNA to modulate protein translation at viral amplification site early in flavivirus infection
Authors: Överby Anna , Peters Marie , Lindqvist Richard , Kassa Eszter , Yau Wai-Lok , Sengupta Pallabi , Sabouri Nasim , Ivarsson Ylva , Lundmark Richard
Published: July 2024

Flaviviruses are RNA viruses that cause serious diseases in humans, with currently no antivirals available. Targeting host factors is emerging as an attractive antiviral approach, but first we need to understand basics of which host proteins are hijacked and why. Here, using a combination of fluorescence microscopy, knock-down, crosslinking immunoprecipitation sequencing, mass spectrometry, and biophysical assays, we identify nucleoporin-153 (NUP153) as a proviral factor during flavivirus infection. We show that NUP153 is recruited to the virus amplification site on the endoplasmic reticulum and needed early on during infection. We find that NUP153 interacts with the viral proteins NS3 and NS5, and a highly conserved G-rich motif on the viral RNA. The interactions promote the production of viral structural proteins, leading to an efficient virion assembly, virus release and spread to new cells. Importantly, we identifyNUP153 as a key regulator in viral polyprotein translation, a mechanism that appears conserved among flaviviruses.
Genetic Factor Analysis for Characterizing Phenome-Wide Patterns
of Genetic Pleiotropy
Authors: Morrison Jean , Willwerscheid Jason , Sylvertooth Dhajanae , He Xin , Stephens Matthew
Published: July 2024

Genetic associations shared by multiple traits provide evidence about the biological role of disease associated variants. We propose Genetic Factor Analysis (GFA), a multi-phenotype analysis method that identifies common patterns of cross-trait associations, the signatures of shared biological processes. GFA overcomes many limitations of alternative methods by automatically selecting the number of factors, accounting for sample overlap, and allowing factors to be non-orthogonal. We apply GFA to analysis of 22 common risk factors for coronary artery disease (CAD), and type 2 diabetes (T2D), allowing us to partition the heritability of CAD, T2D, and risk factors into 13 pleiotropic components. This analysis reveals, among other findings, that about 8% of the heritability of BMI is mediated by factors that do not contribute do CAD or T2D risk. In a second application, we use GFA to obtain a biologically meaningful decomposition of a large set of blood cell composition phenotypes and show that accounting for overlapping samples is critical to obtaining this result.

Published: July 2024

Introduction:
Effective communication between doctors and patients is crucial for the well-being of individuals diagnosed with cancer. This study aimed to develop and validate a cancer-specific Doctor-Patient Communication Satisfaction Scale (DPCSS-Cancer) from the patients' perspective.
Methods
Initial items were generated through literature review. Content validity was assessed via feedback from five experts, while face validity was determined through cognitive interviews with 13 patients. The revised DPCSS-Cancer was subsequently tested in a sample of 200 cancer patients to assess test-retest stability, internal consistency, factor structure, and criterion-related validity.
Results
The development process resulted in a 15-item DPCSS-Cancer across two dimensions, using a 4-point rating scale (1 = strongly disagree to 4 = strongly agree). The item-level Content Validity Index (I-CVI) ranged from 0.8 to 1.0, with a scale-level CVI of 0.96. Following expert and patient feedback, no items were eliminated, but modifications were made to item wording. In formal testing, the overall Cronbach’s alpha was 0.96, with 0.89 for the first dimension and 0.95 for the second. Test-retest reliability was established at 0.82. The two-dimensional structure was partially confirmed. Criterion-related validity was supported through a significant positive correlation with a measure of trust in the physician (r = 0.86). Factors contributing to higher DPCSS-Cancer scores were identified.
Conclusion
The DPCSS-Cancer shows satisfactory reliability and validity, making it a viable patient-reported outcome measure for assessing cancer patients' satisfaction with doctor-patient communication.

Introduction:
Chlorophyllin (CHL) effectively decreases the side effects of radiotherapy (RT) by scavenging radiation-induced free radicals and reactive oxygen species in preclinical trials. This study aims to assess the efficacy of oral CHL for the treatment of brain radionecrosis in patients with diffuse glioma.
Methods
This is a phase 2 trial prospective, interventional study. Adults (> 18 years) with a histological diagnosis of diffuse glioma developing radionecrosis will be eligible for the study. Radionecrosis will be identified using standard imaging protocols with magnetic resonance imaging (MRI) with or without positron emission tomography (PET). Patients will be accrued in two strata: symptomatic (stratum A) and asymptomatic (stratum B). Chlorophyllin will be prescribed to all patients using a morning oral dose of 750 mg before breakfast for 3 months. In addition, participants in stratum A will be given a tapering dose of dexamethasone for 1 month, while stratum B won’t be receiving any steroids. Imaging with an MRI brain protocol and PET scan will be planned at 1 month and MRI at 3 months after starting CHL. The primary endpoint is the clinical-radiological response at 1 month. Secondary endpoints include response at 3 months, biological responses, survival analysis, and quality-of-life scores. The total sample size is 118 (60 and 58 in stratum A and B, respectively), with one interim analysis planned.
Discussion
Radionecrosis leads to significant morbidity and is usually treated with corticosteroids, which can lead to several side effects on both acute and long-term use. Refractory radionecrosis requires treatment with bevacizumab or surgical resection. Chlorophyllin is a cheap, safe, and readily available phytopharmaceutical drug, which is being investigated in the phase 2 study and, if proven effective, can be considered an alternative for treating radionecrosis.
Trial Registration:
The trial is registered on the Clinical Trial Registry India (CTRI): CTRI/2023/08/056166 and ClinicalTrials.gov: NCT06016452.

Published: July 2024

Lehr-/Lernmaterialien, die mithilfe einer entsprechenden Lizenz als Open Educational Resources (OER) veröffentlicht werden, werden grosse Potenziale zugeschrieben, um über die Hochschullehre in den Austausch zu treten und diese kollaborativ weiterzuentwickeln. Dazu bedarf es einer gemeinschaftlichen Open Educational Practice (OEP), die eine neue transformative Kultur des Teilens ermöglicht. Im Projekt InDigO wurde die kollaborative Nutzung und Weiterentwicklung bestehender OER am Beispiel der inklusionsbezogenen Lehrer:innenbildung in NRW begleitend erforscht. Dazu wurden durch Gruppendiskussionen und Logbücher qualitative Daten erhoben und inhaltsanalytisch ausgewertet. Es konnten vielfältige Herausforderungen identifiziert werden, die den gesamten Adoptionsprozess von OER betreffen. Weiter konnten entsprechende Gelingensbedingungen herausgearbeitet werden. So gilt es beispielsweise, die Kompetenzentwicklung der Lehrenden zu fokussieren. Zudem kann gezeigt werden, dass die Öffnung der Lehre einen grösseren Einfluss auf die Kultur des Teilens hat als die Offenheit der Materialien.

Une goutte d’eau est un monde infinitésimal, totalement inconnu. J’ai pu observer au microscope qu’une vie minuscule bouillonne, foisonne dans à peine 1 cl d’eau. Des êtres vivent, se reproduisent, se nourrissent, et meurent à une une échelle qui nous est étrangère. À cette échelle une heure peut représenter une vie. Je propose ainsi de représenter les micro-organismes d’une goutte d’eau de la baie de Villefranche en Méditerranée, comme tentative pour découvrir et révéler le peuple invisible, dont le raffinement et la complexité m’inspirent. À travers ce travail pluridisciplinaire, j’interroge les origines de la photographie avec le cyanotype, et je m’approprie la microscopie scientifique.

Women’s Empowerment in Rara Asmoro Community: An Organizational Culture in Shadow Puppetry Performances
Authors: Ramonita Latifa , Sukandar Rudi , Widowati Dewi
Published: July 2024

The research discussed that the woman dalang was still not considered equal to male ones in shadow puppetry performances despite being developed in the Mataram Kingdom era. Various reasons caused this phenomenon, such as the audience's preferences for men's dalangs. To respond to this condition, an all-women's karawitan community, Rara Asmoro, emerged in Surakarta to give support to many women who love wayang arts. This community sought to embrace these women's potential to then jointly promote and strengthen their skills in the field of Javanese art and culture. The research attempted to analyze the organizational culture formed in the Rara Asmoro community as an effort to empower women in the Javanese wayang art. The research applied a qualitative descriptive method to obtain a complete picture of the problem by interviewing the leader of Rara Asmoro and its four members. It finds a significance of the leader in empowering its members, fostering their confidence and talents, and expanding their opportunities for networking within the Wayang world. The dynamics of the organizational culture in the community allow everyone to switch roles: as a dalang, as a karawitan player, and as a singer, which opens opportunities for all members to have added value and skills. Conflicts are always resolved in a democratic and respectful manner, in which the leader keeps all of her members close as a family. However, internally, concertive control has not been fully implemented in the organization as it is still centralized on the leader.

Authors: Rachmawati Dewi , Fitriyani Lamria Raya
Published: July 2024

The research was conducted to determine the participation of the people of Penglipuran village in developing their village as a tourism village. Tourism development in an area certainly needed to be supported by the surrounding community. For this reason, community participation was essential, especially in tourism areas such as Penglipuran Tourism Village, Bali Island. The research applied a constructivism paradigm with descriptive qualitative research methods. The informants interviewed were the leaders of the traditional village, commonly called Kelian, as well as the people in Penglipuran village. The answers from the informants were analyzed using the theory of social change and the theory of community participation. Based on the results, community participation in Penglipuran village is on the partnership ladder. Currently, it is classified as a success because there is an opportunity for the community to be actively involved in conveying it to the village government. According to Cohen and Uphoff, in the decision-making process, Kelian, as a traditional village leader, has limited authority in connection with the concept of community participation. Program planning and decisions are formulated with all members of the village community. Likewise, during the implementation and evaluation stages of the program, even at the stage of enjoying the results, the entire village community is also involved.

Published: July 2024

The research objectively analyzed artists’ actions and strategic reactions in the urban areas of Bandung and Yogyakarta in Indonesia during the extremely turbulent COVID-19 pandemic from March 2020 to early 2021. The pandemic greatly impacted the lives of artists and practitioners because of stringent governmental prohibitions that prohibited public art events. The research examined practitioners’ experiences concerning their reliance or autonomy from government funding when engaging in arts-related endeavors. The research methodology was based on gathering data from social media and field investigations; a comprehensive collection of posters, photos, and relevant notes was compiled using a cultural studies framework. In addition, interviews were performed with arts practitioners and communities, specifically examining their involvement on social media platforms. A detailed investigation was conducted by carefully analyzing the interview data to clarify the differences between art practitioners in Bandung and Yogyakarta. It is found that the research distinguishes between individuals who receive government sponsorship and those who operate independently. It enhances the overall comprehension of power dynamics between arts practitioners and the government in the distinct setting of the COVID-19 epidemic, including those who operated autonomously. The research utilizes a cultural studies framework to examine the power dynamics between artists and the government in the context of the COVID-19 pandemic.

Authors: Gürbüz Mehmet Ali , Kardeş Tuğçe Ayşe
Published: July 2024

Sunflower is grown under both rainfed and irrigated conditions in all regions to meet the vegetable oil needs of Türkiye, however, in the Thrace region, it is the main rotation crop grown under rainfed conditions after wheat. This study was conducted in the Thrace Region between 2013 and 2016 in order to evaluate the parameters that can be used as an index for nitrogen fertilization recommendations for sunflower plant. For this purpose, organic matter and saturation were determined in soil samples taken from 0-20 cm depth before the experiment and ammonium and nitrate contents were determined in soil samples taken from 0-30 cm, 30-60 cm, and 60-90 cm depths. Within the scope of the study, 27 field trials were conducted over four years. Nitrogen levels of 0 (control), 3, 6, 9, and 12 kg da-1 were implemented in the trials conducted in a Latin square experimental design. In this study, log (279.9-y) = log279.9-0.090b1-0.117x Mitscherlich calibration equations were determined based on 0-30 cm ammonium+nitrate content in the soil.
The Use of Hose Reel Irrigation Machines and Energy Efficient Components in Irrigation
Authors: Polat Turgay , Çolak Ahmet
Published: July 2024

The energy consumed for irrigation is one of the most important inputs in crop production. Irrigation water is distributed within the parcel with minimum loss by using winged or gun systems together with a hose reel irrigation machine (HRIM). The increase in the amount of energy consumed for irrigation increases the cost of the unit product. To reduce the unit product cost, irrigation systems must be used with energy-efficiency units. Frequency converters (FC), pressure transmitters (PT), and programmable logic controllers (PLC) are among the components used to provide energy efficiency. A change in the amount of current drawn by the motors according to the changes in the required flow rate in the pumping facilities is possible by using FC, PT, and PLC. In addition, with more than one motor pump pair; it is necessary to use FC and PLC to be used by connecting in parallel, to operate with the principle of co-aging, and to make a soft start. Instantaneous pressure information is transmitted to PLC and FC via a PT to be installed on the collector in the discharge line in systems with parallel-connected pumps. In this way, the motor revolutions used to drive the pumps are changed via FC, in real-time according to the changes in the flow. Thus, pump-motor pairs are operated with the principle of "constant pressure variable flow" and energy savings are achieved.

The increasing occurrence of saxitoxins in freshwaters is becoming a concern for water treatment facilities owing to its structural properties which make it resistant to oxidation at pH < 8. Hence, it is crucial to be able to monitor these toxins in surface and drinking water to protect public health. This review aims to outline the current state of knowledge related to the occurrence of saxitoxins in freshwaters and its removal strategies and provide a critical assessment of the detection methods to provide a basis for further development. Temperature and nutrient content are some of the factors that influence the production of saxitoxins in surface waters. A high dose of sodium hypochlorite with sufficient contact time or activated carbon has been shown to efficiently remove extracellular saxitoxins to meet the drinking water guidelines. While HILIC-MS has proven to be a powerful technology for more sensitive and reliable detection of saxitoxin and variants after solid phase extraction, ELISA is cost-effective and easy to use and is used by Ohio EPA for surveillance with a limit of detection of 0.015 μg/L. However, there is a need for the development of cost-effective and sensitive techniques that can quantify the variants of saxitoxin.

Published: July 2024

Background:

In recent years, the rapid development of deep learning technology has had
a significant impact on the prediction of DNA-binding proteins. Deep neural networks can automatically
learn complex features in protein and DNA sequences, improving prediction accuracy and
generalization capabilities.

Objective:

This article mainly establishes a meta-migration model and combines it with a deep learning
model to predict DNA-binding proteins.

Methods:

This study introduces a meta-learning algorithm based on transfer learning, which helps
achieve rapid learning and adaptation to new tasks. In addition, normalized Moreau-Broto autocorrelation
attributes (NMBAC), position-specific scoring matrix-discrete cosine transform (PSSMDCT),
and position-specific scoring matrix-discrete wavelet transform (PSSM-DWT) are also used
for feature extraction. Finally, the prediction of DBP is achieved through the deep neural network
model based on the attention mechanism.

Results:

This paper first establishes the basis of deep meta-transfer learning and uses the PDB186
data set as the benchmark to extract features using NMBAC, PSSM-DCT, and PSSM-DWT, respectively,
and compare the fused features in pairs, and finally obtain the fused feature process. Through
deep learning processing, it is concluded that the fused feature prediction effect is the best. At the
same time, compared with the currently popular models, there are obvious improvements in the
ACC, MCC, SN and Spec evaluation indicators.

Conclusion:

Finally, it was concluded that the method used in this article can effectively predict
DNA-binding proteins and show more significant performance.

Published: July 2024

Background

The incidence of human immunodeficiency virus (HIV)-acquired immune deficiency syndrome (AIDS) remains high in Indonesia. Therefore, HIV-AIDS prevention and control programs have been established for adolescents aged 15–24 years based on the United Nations Sustainable Development Goals. Internal risk factors related to risky sexual behavior and external risk factors associated with exposure to pornography through the media are major hurdles that need to be overcome in efforts to prevent HIV-AIDS among adolescents. Meanwhile, individual protective factors through self-control and adolescent resilience strongly impact the enhancement of HIV-AIDS prevention behavior. This study aimed to determine whether internal and external risk factors and individual and sociocultural protective factors exert influences on adolescent resilience and HIV-AIDS prevention behavior among adolescents.

Methods

This research employed a descriptive quantitative design with a cross-sectional approach. The population consisted of high school students aged 15–19 years in Jakarta, and a sample of 619 students was taken through proportional stratified random sampling. Inferential analysis was conducted using partial least squares structural equation modeling.

Results

The data analysis revealed that adolescent resilience (β-value = 0.423; t = 12.129), internal risk factors (β-value = 0.292; t = 10.903), and external risk factors (β-value = -0.088; t = 6.127) most significantly influenced HIV-AIDS prevention behavior, with significant negative impacts. The sub-variable that most strongly determined the presence of HIV-AIDS prevention behavior (Y2) was self-control (λ = 0.983), and the one that did so most weakly was negative cognition (λ = 0.875).

Conclusion

Adolescent resilience is a crucial factor in enhancing HIV-AIDS prevention behavior among adolescents as it influences adolescents’ beliefs, boosts their self-confidence, fosters emotional insight, and develops social skills and empathy toward others. Thus, enhancing it through HIV-AIDS prevention programs is essential.
Investigation of the Effects of Different Phases of TiO2 Nanoparticles on PVA Membranes
Authors: Mehto Akanksha , Chauhan Jyotsna , Mehto Varsha R.
Published: July 2024

Introduction:

PVA/TiO2 nanocomposite membranes are prepared by solution
casting technique where different phases of TiO2 nanoparticles like brookite, brookiterutile
and rutile are dispersed in PVA matrix. Sol-gel method was employed to prepare
TiO2 nanoparticles, while different phases of TiO2 have been obtained by controlling the
calcination temperature.

Methods:

PVA/TiO2 nanocomposite membranes were characterized by XRD, FTIR,
AFM, TEM, UV-visible and PL techniques. XRD results confirmed the presence of different
phases of TiO2, exhibiting 3.3 nm, 8.4 nm, and 35.7 nm mean crystalline size. The
XRD studies also confirmed that TiO2 nanoparticles became properly dispersed to the
PVA matrix, leading to increased PVA crystallinity after doping of different phases of
TiO2 nanoparticles. UV-visible analysis revealed an increase in absorption intensity and
peak position shifts slightly towards longer wavelengths, which indicates that nanofillers
tuned the band gap of PVA. The doping of the TiO2 (brookite) phase in the PVA matrix
results in a decreased in PL intensity.

Results:

This suggests that the PVA/TiO2 (brookite) membrane exhibits a greater degree
of photocatalytic activity in comparison to the other two composites. According to the
FTIR investigation, the hydroxyl (OH) groups present in PVA interact with the dopants
Ti+ ions via intra- and intermolecular hydrogen bonds to produce charge transfer complexes
(CTC). The AFM study shows surface roughness details for PVA and PVA/TiO2
composite membranes. The average grain size of TiO2 nanoparticles calculated from
TEM images is in good agreement with the grain size calculated by XRD.

Conclusion:

By adjusting the phase of TiO2 nanoparticles into PVA matrix, composites
can be developed that are optimized for a variety of applications such as water purification,
UV protection, self-cleaning surfaces, lithium-ion batteries, and optoelectronic devices.
Multi-factor Authentication Framework for Secured Data Access in Cloud Computing
Authors: Rajakumar P. , Partheeban N.
Published: July 2024

Aims and Background:

Accessing data services on the cloud raises serious concerns
about security and privacy. To verify a client's stated identity, the existing authentication approach
uses just one authentication factor. However, traditional techniques of one-factor authentication
are inefficient since they demand an excessive amount of user information and expose their private
data to eavesdropping.

Methods:

Cloud-based data storage is susceptible to both external and internal threats. Information
security relies heavily on authentication, which is a method for verifying user identities
before granting them access to protected data. When it comes to protecting data in a cloud computing
environment from the most cutting-edge methods of attack, traditional password authentication
simply isn't enough. For the purpose of protecting user identities in the cloud, this study presents
interactive multi-layer authentication systems. Various access control policies are used when
validating users in the cloud. Registration, permissions, and authentication factors for users are all
parts of the cloud app's security process.

Results:

An intrusion detection system is built into the security mechanism to help identify people
who could be malevolent. Various techniques are available for user identity verification, including
intrusion detection, access control, and multi-factor authentication. The last step is to encrypt the
data so that no one else can read it.

Conclusion:

To guarantee the effectiveness and accuracy of the suggested frameworks and methodology,
they are experimentally evaluated. There were few false positives and a high detection rate.
O 25 de Abril como memória construída nos discursos presidenciais de comemoração: negação e construção de um posicionamento enunciativo
Authors: Marques Maria Aldina , Duarte Isabel Margarida
Published: July 2024

Nos discursos de comemoração, o evento comemorado é um tópico central que implica um posicionamento enunciativo do locutor com consequências na construção dos sentidos do discurso. Os discursos proferidos pelos presidentes na comemoração anual do 25 de Abril mostram como os sucessivos locutores se detêm na representação discursiva do evento celebrado. O estatuto presidencial, de mais alto magistrado da nação, confere-lhe legitimidade para coconstruir com a comunidade portuguesa uma memória de Abril, que determina o significado simbólico do evento. Num quadro de análise da construção da referenciação nos discursos de comemoração de Abril, centramo-nos na análise das estruturas de negação e no modo como contribuem para a construção dessa memória. O corpus de análise é constituído por excertos de discursos presidenciais de comemoração de Abril, entre 1977 e 2011. Pretendemos determinar as funções discursivas destas estruturas, explorando as implicações da sua natureza polifónica ou dialógica nos sentidos do discurso.
