A Comprehensive Review on the Role of Obesity in Functional Cognition (Part I): Epidemiology and Alternations in Brain Structure
Authors: Callaghan Ronnie
Published: September 2023

The condition of obesity, which is defined by an excessive amount of adipose tissue, is being increasingly acknowledged as having significant consequences for the structure and functioning of the brain. Numerous studies have demonstrated that obesity is linked to significant modifications in the structure of the brain, encompassing variations in the volume of gray matter, the integrity of white matter, and modifications in particular brain regions responsible for regulating appetite and cognitive control. For example, research employing neuroimaging methodologies such as magnetic resonance imaging has consistently indicated that individuals with obesity frequently display diminished gray matter volume in areas such as the prefrontal cortex, which is known to play a critical role in processes such as decision-making and impulse control. Furthermore, there have been observations of white matter abnormalities that impact the interconnection among brain regions responsible for hunger regulation and reward processing. These abnormalities may potentially play a role in the development of overeating tendencies and compromised self-control. The aforementioned alterations in structure are not solely connected to obesity, but are also correlated with cognitive deficits, namely in domains pertaining to memory, attention, and executive functioning. Gaining a comprehensive understanding of the complex correlation between obesity and brain structure is of utmost importance, as it provides valuable insights into the neurological foundations of cognitive impairments in individuals affected by obesity. Moreover, this knowledge serves as a basis for the creation of specific interventions aimed at alleviating the cognitive repercussions associated with this widespread public health issue.

Published: September 2023

The present study aims to examine the effect of the flipped classroom model on the academic achievement and critical-analytic thinking skills of students from different socio-economic backgrounds. For this purpose, two schools in the same province, attended by children from families with varying socio-economic levels, were included in the study. The study sample consisted of a total of 82 students: 30 from a secondary school with students from a low socio-economic background and 52 from another secondary school with students from a high socio-economic background in the 2021-2022 academic year. The study was designed based on the quasi-experimental design with pretest-posttest control groups. Experimental and control groups consisting of one class each, and four classes in total, were selected from the schools using the random assignment method. The total application period was 9 weeks while the duration of the experimental applications was 7 weeks (28 class hours). In the present study utilizing Edpuzzle, an online platform, interactive videos were developed in accordance with the learning outcomes of the course. Data were collected using the 25-item “Sun, Earth and Moon Achievement Test” applied to determine the learning levels of the students and the 72-item “Cornell Conditional Reasoning Test” applied to measure critical-analytic thinking skills. In conclusion, it was revealed that although there was no significant change in critical-analytic thinking skills, the flipped classroom model provided a significant increase in the academic achievement and critical-analytic thinking skills of students from both socio-economic backgrounds.

Authors: Tian Siqing , Li Xiao , Fang Xiaolin , Qi Xiaozhong , Li Jichao
Published: September 2023

The available surface defect detection methods for disposable wooden spoons still involve screening with the naked eye. This detection method is not only inefficient but also accompanied by problems such as false detection and missed detection. Therefore, this paper proposes a detection method based on an improved YOLOv5 network model (YOLOv5-TSPP). This method uses the K-Means ++ algorithm to cluster the target samples in the data set to obtain anchor frames that are more in line with different target scales. The Coordinate Attention module is added to the backbone network of the YOLOv5 network model to improve the feature extraction ability of the model. A new SPP module is added to the backbone network to increase the important features in the receptive field extraction network to improve the detection accuracy of small targets. The experimental results show: The YOLOv5-TSPP algorithm has better detection performance and the mAP of defect detection reaches 80.3%, which is 9.2% higher than that of the YOLOv5 algorithm. Among them, the detection accuracy of black knot defect reached 98.6%, the detection accuracy of back crack defect reached 92.1%, and the detection accuracy of mineral line defect reached 92.3%.

The use of the tracer 18F-fluoro-3'-deoxy-3'-L-fluorothymidine ([18F]FLT) in positron emission tomography (PET) has been shown to be an effective tool for assessing tumor aggressiveness and early response to therapy. In this study, we investigated the applicability of [18F]FLT/PET to study the antitumor and anti–lung metastatic effects of rosmarinic acid (RA) in highly invasive breast cancer. 4T1 mammary carcinoma cells were injected into the flank of female Balb/c mice. The animals were treated daily with RA until day 21 after the inoculation of tumor cells. [18F]FLT/PET imaging was used to evaluate the response of primary tumors and lung metastases to RA treatment. PET Images showed a decreased [18F]FLT uptake in the lungs of mice after RA treatment. The antitumor effect of RA appears to be related to the inhibition of cell migration, cell proliferation, and blood vessel formation in the primary tumor. Furthermore, the inflammatory response was modulated by RA, which reduced the accumulation of mast cells and neutrophils in the primary tumor and of macrophages in the lungs. In conclusion, [18F]FLT/PET demonstrates the antitumor and antimetastatic effects of RA in a 4T1 breast tumor model. Furthermore, the findings suggest that RA modulates tumor angiogenesis and inflammation, resulting in antitumor and antimetastatic effects in a 4T1 breast carcinoma model.

Authors: Hasan Nailul
Published: September 2023

A quantum ericson-engine that consists of a single particle with multiple states, has been explored. It is a quantum analogy to the classical ericson-engine consisting of a combination of two isothermal processes and two isobaric processes. By analogizing a particle in a one-dimensional infinite potential well as a gas in a piston-cylinder, quantum thermodynamic processes in a quantum ericson-engine can be explained from the analogies of classical processes such as isothermal, and isobaric.  The results of the research show that the thermal efficiency of the quantum ericson-engine has similarities with the classical ericson-engine.

Educator and Mentor Are Key Figures in Formation of Educational-Technological National Sovereignty
Authors: Likholetov Valeriy V. , Abdullin Asat G.
Published: October 2023

Introduction. The loss of the domestic education system’s world leadership has contributed to a sharp decline in the social status of a teacher. The imbalances in the sphere of upbringing-education led to the deformation of the economy and reduction of national security of the state. However, the beginning of a special military operation to protect the lives of civilians of the Donetsk and Lugansk Peopleʼs Republics in Ukraine has revised the problem of restoring and building up the educational-technological sovereignty of the country. The purpose of the article is to analyze the current problems in the sphere of education and training of young people, to identify old and new roles of the teacher-mentor and the degree of influence of the institute of mentoring on the formation of educationaltechnological sovereignty of the country.
Materials and Methods. When analyzing and summarizing the most significant works devoted to both timetested and new models of modern mentoring, as well as substantiating and synthesizing the concept of “educational and technological sovereignty”, the authors relied on historical and interdisciplinary approaches, the principles of “educational education” by I. Herbart, the ideological legacy of K. D. Ushinsky on “public education”, the developments of domestic philosophical, sociological, psychological and pedagogical schools, the experience accumulated in the country in the upbringing and education of young people and adults.
Results. The study of the problem of the formation of the educational and technological sovereignty of the country proves that mentoring as a developing social technology improves the conditions for the local circulation of professional information in society. Adequate to the tasks of “public education” and “educational education”, it contributes to the formation of a holistic picture of the world among young people in the course of a direct exchange of cultural, historical, scientific, technological, spiritual and moral knowledge-codes between the subjects of interaction (mentor and ward). Mentoring models work well in management, scientific, educational, industrial, technological and cultural spheres, in healthcare, social security, and the spiritual and religious environment, blocking threats to the national security of the country.
Discussion and Conclusion. The obtained results contribute to the scientific analysis of the phenomenon of mentoring as an interdisciplinary problem, initiate the study of its new forms, which are adequate to the conditions of digitalization of modern society. We hope that they will contribute to the strengthening of the domestic institute of mentoring and, as a result, to building up the cultural, educational and technological sovereignty of the country.
Rework investigation in residential building projects: Cost, factors and effects
Authors: Mahamid Ibrahim
Published: October 2023

This article aims at investigating rework cost, factors and effects in residential building projects in the West Bank – Palestine. Questionnaire survey is used to collect and rank the main factors and effects of rework from consultants' and constructors' point of view. Respondents show that more than 80% of the projects completed with rework cost of value greater than 5% of the total project cost. Overall, respondents' view concludes that the top rework factors include: mistakes in design, unskilled labors, unqualified subcontractors, non-conformance with required specifications, and bid awarding policy. Respondents indicate that the main effects of rework are cost overrun, project time extension, material waste excess and profit reduction. Spearman correlation test concludes a good correlation between contractors and consultants in ranking of rework factors and effects. Data collected from 47 residential projects reveal a high rework impact on cost overrun in construction projects. The results of this study would be helpful for researchers and professionals to guide their efforts to minimize rework in construction projects and to improve projects outcomes in term of cost, time and quality.
Spiritual Identity Reconstruction among Australian LGBTQA+ Christians from Evangelical Traditions
Authors: Hollier Joel
Published: September 2023

This article explores the spiritual journeys of LGBTQA+ people seeking to reconstruct their faith as minorities within, or excluded from, evangelical traditions. Twenty-four queer individuals with histories in evangelical settings took part in in-depth interviews. Twenty-two participants had restructured traditional Christian doctrines to integrate their religious and queer selves. In the process of reconstructing religious or spiritual identities, participants’ understanding of God took on a more enigmatic form, larger than the boundaries that traditional orthodoxy had placed on the nature of the divine. It was found that LGBTQA+ individuals began to ‘take God out of the box’, showed a willingness to approach ‘heresy’, and attempted (with varied success) to separate religion from spirituality. This reimagining of God from the margins is theorised as an expression of spiritual resilience and a lay-led form of queering theology that can benefit the broader church.

This paper analyses the different types of intellectuals, e.g. Bauman’s legislators and interpreters, and the role they take in researching and/or speaking for and/or against the other in religion.
Jules Monchanin, Henri Le Saux/Abhishiktananda and the Hindu-Christian Encounter
Authors: Oldmeadow Henry
Published: September 2023

This article focuses on two Benedictine monks, Fathers Jules Monchanin and Henri Le Saux, who spent many years in the sub-continent where they immersed themselves in Indian philosophy and spirituality. The article compares and contrasts their differing responses to the “problem” of the relationship between Christianity and the Hindu tradition. The article argues that the more inclusivist understanding of Hinduism by Le Saux (who became better known under his Indian name Abhishiktananda) allowed him to reconcile the tensions and contradictions evident in the life and work of his fellow-monk. The article also explores Abhishiktananda’s understanding of the ideal of renunciation as a meeting point for the two traditions.
Interaction within a dance class for adults with intellectual disabilities
Authors: Slaney Caitlin , Easton Catherine
Published: September 2023

Background: Environmental factors have a significant role in facilitating and limiting participation of individuals with intellectual disabilities in everyday activities. Creating accessible communication environments within leisure activities offers opportunities for enhanced participation and interaction. Method: An ethnographic approach was used to observe and analyze interactions within a dance class for adults with intellectual disabilities. Observation was used alongside questionnaires, interviews, and assessment tools to identify and analyze patterns of interaction among the students and professionals. Results: Participation in the dance class enabled the students to build social connections with each other, which in turn further facilitated interaction and joint participation. Professionals and students implemented a range of communication strategies in response to their aims and expectations. Through participation in the study, the teacher's awareness of her use of strategies increased. Discussion and conclusion: Further research is needed to understand how interaction opportunities can be further maximized during everyday activities for individuals with intellectual disabilities.
‘Typing with dementia’
Authors: Bös Birte , Schneider Carolin
Published: September 2023

Background: While there is a substantial amount of pragmatic research on online health discourse, social media contexts actively involving persons living with dementia have been largely neglected so far. This study, which is rooted in the social-constructionist paradigm, explores processes of self-positioning on a public message board for persons living with dementia provided by a non-profit health organization. Method: The study is based on a pilot corpus of 15 sample threads on the public message board, and it investigates the referencing and predication practices employed by the members of this virtual community of practice. Results: Their interactions reveal processes of identity construction which clearly debunk the popular myth of ‘loss of self’ in dementia. Conclusion: Going beyond the categories, characteristics, and activities conventionally ascribed to persons living with dementia, participants challenge dementia-related stereotypes and ultimately contribute to a more multifaceted picture of living with dementia.
Forever underground, forever black

Published: September 2023

Because it has been integral to the history and marketing of Bandung death metal, the satellite town of Ujung Berung aka Ujungbronx, in Bandung’s outer southeastern suburbs, has become a revered and romanticized myth throughout all of Indonesia’s underground scenes. The Indonesian underground constitutes the mythscape or page where alternative myths are promulgated, expanded, debated, opposed, or reimagined. While the governing myth of Ujung Berung scene as paramount is widely accepted in West Java province, it is accepted somewhat reluctantly, and with mild criticism, in the East Javanese and Jogjakarta scenes. However, in Surabaya, there is a recognition that the moment when the governing myth could have been overthrown, at least within East Java, is long past. History belongs to the victors.
Variability of heatwaves across Vietnam in recent decades
Authors: Pham Thi Ly , Pham Thanh Ha , Phan Van Tan , Vu Thuan Yen
Published: October 2023

There have been several studies on heatwaves (HW) in Vietnam but they all focused on an individual heatwave characteristic. A comprehensive understanding of heat waves is crucial for effective research on their impacts and for making plans for climate change mitigation and adaptation strategies in the country. This study investigates the spatial variability and changing trends in heatwave characteristics across the climatic sub-regions of Vietnam. The analysis is based on the observed daily maximum temperature (Tx) recorded at 144 meteorological stations in the period of 1980-2018. HW is identified using a relative threshold, which is the local 90th percentile of Tx within 183 days during the summer (1st April - 30th September). Results showed that: (1) The threshold values used to determine HW events varied among sub-regions and stations due to their geographical locations; (2) Across the country, HWs were observed to be more frequent, intense, severe, and longer-lasting in the North Delta and North Central sub-regions compared to others; (3) Over recent decades, both the frequency and severity of HWs have significantly increased across Vietnam, particularly in the North-Delta and North Central sub-regions. However, the changing trends in HW duration and intensity remain unclear.

Routine use of antibiotics for dental implant installation is widely applied in dental practice to prevent postoperative infection and implant loss. However, the effectiveness and necessity of such protocols have not been consensual in the literature. This study aimed to evaluate the effect of antibiotic prophylaxis on survival of dental implants placed in clinically healthy patients by unexperienced operators. A double-blind, randomized, placebo-controlled trial was conducted. Ninety patients who received between 2 and 4 dental implants by unexperienced operators were enrolled in this study. Patients were randomly allocated in 2 groups. For the antibiotic group (n = 47), patients received 1 g of preoperative amoxicillin; in the placebo group (n = 43), patients received preoperative placebo administration. Each patient was evaluated preoperatively, 2 days, and 7 days postoperatively. Factors evaluated were mouth opening amplitude, assessment of referred pain through a visual analogue scale, and characteristic signs of infection (presence of fistula, ulceration in the surgical wound, tissue necrosis at the edges of the wound, dehiscence of the surgical flap, and presence of purulent exudate in the surgical wound). Implant survival was evaluated until 90 days postsurgical procedure. Results showed that there were no statistically significant differences in postoperative healing, swelling, and pain. However, more loss of dental implants was observed in the placebo group (14.9% vs 2.3%). Use of antibiotic prophylaxis reduced implant loss that was previously placed by unexperienced operators.
Profissionalização do político: uma análise multidimensional dos deputados federais brasileiros
Authors: Gabriel Gabryela , Codato Adriano
Published: October 2023

Introdução: Na literatura de Ciência Política não há um critério bem estabelecido para se medir o grau de profissionalização dos políticos. Este artigo revisa um índice proposto para avaliar a profissionalização dos membros do Parlamento do Reino Unido adaptando-o ao caso dos deputados federais brasileiros eleitos em 2014.

Materiais e métodos: O índice original de profissionalização é composto por quatro dimensões: 1) grau de comprometimento com a carreira; 2) tipo de background profissional antes de ingressar na atividade parlamentar; 3) idade de entrada no Legislativo (uma proxy para experiência de vida); e 4) ambição política. Após a aplicação do índice aos parlamentares brasileiros que serviram na 55ª legislatura, foram feitos testes de comparação de médias para verificar se os legisladores com status político alto possuíam um grau de profissionalização maior do que os demais. Foi utilizado para separar o grupo de status alto a classificação do Departamento Intersindical de Assessoria Parlamentar (DIAP) que anualmente publica a lista dos 100 Cabeças do Congresso Nacional.

Resultados: Há uma diferença estatisticamente significativa a favor dos deputados de maior destaque. Os parlamentares premiados pelo DIAP são mais profissionais do que os não premiados em três das quatro dimensões analisadas (comprometimento com a carreira, experiência de vida e ambição política).

Discussão: Com as devidas adaptações, o índice de profissionalização mostrou-se consistente e capaz de capturar a distância entre os parlamentares premiados e não premiados pelo DIAP. O uso de um modelo multidimensional é fundamental, pois, mais do que definir quem é ou não político profissional, ele permite medir o quão profissional um determinado político é.
El valor de las armas menos letales en seguridad pública
Authors: Hernandez-Perdomo Elvis , Mun Johnathan
Published: September 2023

Las armas menos letales (AML) han sido objeto de debate en la aplicación de la ley. Gran parte de la literatura se centra en su legalidad y conveniencia, en lugar de su efectividad, particularmente para los organismos de seguridad. Para abordar esa brecha, el presente estudio utiliza un análisis de riesgos financieros avanzados y simulación de escenarios para modelar el retorno de la inversión (ROI, por sus siglas en inglés) del uso de las AML. Utilizando un tipo de AML (The Alternative) como caso de estudio, se encuentra que, si bien los eventos extremos con AML ocurren relativamente con poca frecuencia, en comparación con las armas de fuego convencionales, su impacto en la sociedad es significativo. Por ejemplo, las agencias policiales pueden obtener un ROI entre el 1564% y el 2728%. Por cada dólar invertido en adquirir, equipar y capacitar a un oficial con AML, el beneficio adicional se sitúa entre 16 y 28 dólares. Por lo tanto, las AML no solo reducen el daño colateral, el riesgo reputacional y legal, sino que también previenen muertes innecesarias que erosionan la legitimidad policial y la confianza pública.
The Role of Rubrene Concentration on Dielectric Parameters of Nematic Liquid Crystal
Authors: KOCAKÜLAH Gülsüm
Published: September 2023

In this study, the dielectric parameters of E7 coded nematic liquid crystal (NLC) composites containing the different amounts of rubrene fluorescent dye were investigated. E7, E7+0.5 wt.% Rubrene, and E7+1.0 wt.% Rubrene samples were prepared. Frequency dependent dielectric constants (ɛ′ and ɛ′′), dielectric anisotropy (Δε′), and ac conductivity (σac) graphs of rubrene doped E7 NLC composites were obtained by dielectric spectroscopy method and compared with pure E7 NLC. By using these graphs, relaxation frequency (fR), relaxation time (τR), dielectric strength (δɛ′), and crossover frequency (fc) parameters of the E7 NLC and its rubrene doped composites were determined. An increase in fR from 3.045 MHz to 3.697 MHz for 0 V and from 627 kHz to 686 kHz for 40 V was observed with increasing rubrene concentration. On the other hand, a decrease in τR from 0.052 μs to 0.043 μs for 0 V and from 0.254 μs to 0.232 μs for 40 V was seen with increasing rubrene concentration. Furthermore, an increase in fc from 1.145 MHz to 1.298 MHz was obtained with increasing rubrene concentration. The results show that the dielectric parameters change with the concentration of rubrene and it is thought that this study will provide a basis for investigating the dielectric properties of rubrene doped NLC composites. Moreover, it is concluded that the produced composites are a suitable base material for electro-optical device applications such as smart displays, photonics and electrical circuit elements.

Published: September 2023

The purpose of this work was to evaluate the petroleum sorption capacity of heat-killed fungal discs obtained from Aspergillus ochraceus strain. Effect of various parameters such as biosorbent dose (0.5g-2.5g/100mL), petroleum concentration (0.5-5%), pH (4.0-8.0), contact time (1-12h) and re-usability of biosorbent (1-6) were investigated. Accordingly, the highest biosorption capacity was obtained with 1% petroleum concentration, 1.5 g/100mL heat-killed fungal discs, 10h contact time at pH: 5.0 and room temperature. Additionally, each disc was able to actively use for at least 6 more cycles in biosorption experiments. The specific removal rate was calculated as 0.114 day−1, the rate constant and half-life period were also 1.609 day-1, t1/2 = 0.431, respectively. The kinetic study was described by the pseudo-second order model and the equilibrium modeling was found to be well fitted with Langmuir isotherm. The biosorbent(s) were characterized by Focused Ion Beam Scanning Electron Microscopy (FIB-SEM). Over 80% removal of long-chain n-alkanes by the heat-killed fungal discs was confirmed by GC-MS analysis. Since there has been no similar study investigating the sorption of petroleum with heat-killed Aspergillus ochraceous discs, this novel bio-based sorbent with its low cost, environmentally friendly and easy-to-apply properties can be used in advanced biosorption studies.
Nanoscale Liposome Synthesis for Drug Delivery Applications via Ultrafast Acoustofluidic Micromixing
Authors: POURABDOLLAH VARDİN Ali , YESILOZ Gurkan
Published: September 2023

Nowadays, lipid nanoparticles have gained profound interest in chemical and biomedical engineering. The rapid development of therapeutic nanosystems has led to a need to design suitable approaches to synthesize bio-carriers for efficient drug delivery. Microfluidic methods provide an excellent opportunity to acquire desirable nanoparticle properties, including stability, size, shape, and size distribution, which are often challenging to obtain using conventional bulk synthesis methods. Rapid mixing is a crucial factor in the nanoprecipitation process as it influences the size and size distribution of the nanoparticles. Within this regard, in this work, we report an ultrafast acoustofluidic micromixer to synthesize liposome nanoparticles, which have been widely investigated in the literature as drug carriers due to their biocompatibility and biodegradability. This research has also investigated the influence of glycerol addition to the solvent to control the size of the liposomes. Our findings indicate that utilizing the acoustofluidic platform resulted in the production of nanoscale liposomes with small mean sizes compared to the hydrodynamic flow-focusing (HFF) method. Furthermore, the inclusion of glycerol led to a significant reduction in liposome size. These results emphasize the potential of the proposed approach for the efficient and precise synthesis of liposome nanoparticles with improved characteristics, which can be utilized in various biomedical and drug delivery applications.

Educational Design and Evaluation Models are important factors in e-learning as they provide guidance information for proper strategy organization pursuing both specific learning outcomes and ensuring the main elements of e-learning, such as self-regulation and collaborative learning. The examined educational models of ADDIE, Bloom, and Kirkpatrick are widely known and recognized as models for design and measuring the effectiveness of learning in order to achieve the best possible learning outcomes based on the needs of a specific target group in a specific educational context whether traditional or digital. Specifically, the ADDIE Model is a widely known learning design model used by many educational designers and training programmers to develop education and training programs. The Bloom Taxonomy is a method of building learning goals that follows the process of cognition. The Kirkpatrick Model is a method of evaluating the effectiveness of e-learning and educational programs in general, both in terms of training and business performance of learners. The purpose of this paper was both the investigation of the academic performance, the self-regulated learning and the collaborative learning in relation to the models of ADDIE, Kirkpatrick and Bloom in distance online environments and their effectiveness to the learning process. Meta-analysis was applied for research methodology. After a systematic literature review, we found that only 37 articles were appropriate for meta-analysis. Especially, 23 articles were on the ADDIE model, 9 articles were on the Kirkpatrick model and 5 articles were on the Bloom model. According to the results of this study, we found that all models apply to online process and meet different learning requirements. Regarding the cognitive performance of the trainees, all models supported the effectiveness of distance education. Moreover, the self-regulated learning and the collaborative learning, as factors inextricably linked to the effectiveness of the distance education, were examined in a small number studies in the above models. Finally, all three examined models reinforced students’ positive attitudes and perceptions, even while transferring the acquired knowledge to the workplace.

BACKGROUND: Currently, several patients with dental problems continue to suffer from various defects in the maxillofacial region. Therefore, the methods and techniques of orthopedic replacement for these defects, both as a standalone treatment and within a comprehensive interdisciplinary approach, must be enhanced. The nature of hygienic care and the means used play an important role in increasing the service life of facial epitheses. Literary sources have shown insufficient research in this area. Domestic and foreign literature is generally devoted to methods and means of hygiene for removable dentures. Moreover, the features of structural materials and methods of fixing facial epitheses require the search for other approaches to hygienic care.
AIM: To develop hygiene products for facial epitheses and to substantiate their toxicological safety.
MATERIALS AND METHODS: The care of maxillofacial prostheses using sprays and foams was proposed. To study their cytotoxicity, samples were prepared from photopolymer material for facial prostheses. The samples were treated with spray, foam, or their combination. To test the cytotoxic properties, a primary cell culture of stromal cells isolated from a biopsy of the mucosa of the alveolar process of the mandible was used. The viability of cells and efficiency of the colonization of samples were evaluated after 48 h using culture staining and colorimetric XTT.
RESULTS: Intravital monitoring of stromal cells, extracted from a biopsy of the mucosal lining of the alveolar process in the lower jaw, revealed sustained direct interaction between the cells and the samples, with no signs of necrosis or apoptosis. When staining samples with fixed cells, no red glow of the nuclei of dead cells was detected. The distribution of living cells was uniform in group 4 and less uniform in group 1. The optical density of the medium in each well was significantly different between the groups (p 0.05).
CONCLUSION: The proposed hygienic compositions for the care of facial prostheses using sprays and foams do not have toxic properties and can be implemented in clinical practice.

Published: October 2023

El reguetón es un género musical que ingresó al Perú en la década de los noventa y ha tenido una presencia solapada en adolescentes quienes la bailan por su sensualidad y erotismo, este género musical, en sus orígenes estuvo asociado a un movimiento contracultural que estaba involucrado en un mundo delictuoso en el que se cometían homicidios por ajustes de cuentas, comprometidos en el tráfico de drogas, comercio sexual, abuso sexual contra las adolescentes, trato despectivo a la mujer considerándola objeto de placer, y en ese contexto, el varón se erige como el macho predominante, con lujos y otros signos exteriores de riqueza, rodeado de mujeres exuberantes y jóvenes. Este no es el contexto peruano y, por lo tanto, eso explica la baja presencia de este género. Sobre el reguetón y su relación con las competencias de arte y cultura de adolescentes que cursan el último grado de educación básica con edades de 16 a 18 años, se realizó esta investigación, con un enfoque mixto, con una muestra cuantitativa de 330 adolescentes y una muestra cualitativa de ocho; los instrumentos fueron dos cuestionarios y una entrevista a profundidad, para el tratamiento se empleó estadística y análisis de contenido; los resultados cuantitativos muestran una relación directa, moderada y significativa entre reguetón y las competencias de arte y cultura (r = ,573 y p. = ,000) mientras que los resultados de la entrevista cualitativa revelan que el género musical reguetón no ejerció ninguna influencia en la muestra dada la sólida formación de valores cultivada en el hogar, escuela y comunidad, por lo cual la competencia de arte y cultura fue lograda, por lo que se concluyó que hay una relación moderada entre reguetón, arte y cultura las cuales no han modificado la estructura de valores de los adolescentes. Se recomienda que en futuras investigaciones se elijan zonas geográficas con elevada presencia de delincuencia y consumo de drogas y se emplee el método cualitativo de tipo etnográfico o etnometodológico para una mejor comprensión del tema.
Blockchain Technology for Tourism Post COVID-19

Published: September 2023

During the pandemic, the tourism industry was one of the most severely impacted sectors. As vaccines are now widely available, each government is working to develop a system that can generate a digital vaccine certificate and PCR lab test result to verify that a person has been fully vaccinated or has a negative PCR test result, in order to allow them to enter business premises, travel overseas or cross state borders. However, the use of centralised systems in the development of the digital COVID-19 pass system results in a number of challenges, including the system’s high susceptibility to failures, sluggish and inefficient information transmission, and vulnerability. The goal of this research is to offer a new digital COVID-19 pass based on the proposed “SmartHealthCard” blockchain technology. SmartHealthCard is a decentralised application (dApp) encrypting and hashing user data and safely storing it in a distributed database. Privacy preservation, GDPR compliance, self-sovereignty, KYC compliance and data integrity are featured. This initiative has the potential to benefit the public, healthcare professionals, service providers and the government. SmartHealthCard enables quick verification of tamper-proof COVID-19 tests/vaccines, aiding in COVID-19 transmission control while respecting the user’s right to privacy.
