Authors: Alkahtani Zuhair M.
Published: July 2024

ABSTRACT

Background:

Pediatric dental anxiety poses a significant challenge in the delivery of dental care, often resulting in compromised treatment outcomes and negative experiences for both patients and dental professionals.

Materials and Methods:

A randomized controlled trial (RCT) was conducted involving 120 pediatric dental patients aged 4 to 10 years old, presenting with varying degrees of dental anxiety. Patients were randomly assigned to three groups: Group A received tell-show-do (TSD) technique, Group B received audiovisual distraction (AVD), and Group C received non-pharmacological behavior guidance (NPBG). Anxiety levels were assessed using a standardized anxiety scale before and after the dental procedure. Patient cooperation during treatment, as well as dentist and parent satisfaction, was also evaluated.

Results:

The study revealed significant reductions in anxiety levels across all groups post-treatment. However, Group B (AVD) demonstrated the most substantial reduction in anxiety scores, with a mean decrease of 60% from baseline. Group A (TSD) and Group C (NPBG) showed comparable reductions in anxiety levels, with mean decreases of 45% and 50%, respectively. Patient cooperation during treatment was highest in Group B, followed by Groups C and A. Dentist and parent satisfaction scores were significantly higher in Group B compared to the other groups.

Conclusion:

AVD emerged as the most effective behavioral management technique for treating anxious pediatric dental patients, resulting in significant reductions in anxiety levels and higher levels of patient cooperation during treatment compared to TSD and NPBG techniques.
Exploring the Therapeutic Potential of Omega-3 Fatty Acid Supplementation in Dry Eye Syndrome: An In vitro Investigation
Authors: Alharbi Abdulmajeed
Published: July 2024

ABSTRACT

Background:

Dry eye syndrome (DES) is a prevalent ocular condition characterized by insufficient tear production or excessive tear evaporation, leading to discomfort and visual disturbances. Omega-3 fatty acids have been proposed as a potential therapeutic intervention for DES due to their anti-inflammatory and lipid modulation properties.

Materials and Methods:

Cultured human corneal epithelial cells were exposed to various concentrations of omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), for 72 h. Cell viability was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, while inflammatory cytokine levels (interleukin-6 (IL-6), interleukin-8 (IL-8)) and lipid profile (measured by lipid staining) were evaluated using enzyme-linked immunosorbent assay. Untreated cells served as controls for comparison.

Results:

Omega-3 fatty acid supplementation demonstrated a dose-dependent increase in cell viability compared to untreated cells. At optimal concentrations, EPA and DHA significantly enhanced cell viability by 30% and 35%, respectively (P < 0.05). Moreover, omega-3 fatty acid supplementation led to a significant reduction in inflammatory cytokine levels, with a 50% decrease in IL-6 and IL-8 secretion compared to untreated cells (P < 0.01). Additionally, lipid staining revealed improved lipid profile and organization in corneal epithelial cells following omega-3 fatty acid supplementation, indicative of enhanced tear film stability.

Conclusion:

In vitro findings suggest that omega-3 fatty acid supplementation exerts beneficial effects on cellular markers associated with DES.

Authors: Swathika B , Basheer Syed Nahid , Sriram S , Rajmohan Sujith , Murugesan Sabari , Subramani Savadamoorthi Kamatchi
Published: July 2024

ABSTRACT

Background:

Gutta-percha is commonly used in endodontic therapy for obturating root canals after cleaning and shaping procedures. Warm and cold gutta-percha techniques are two common methods employed for obturation, each with its own advantages and limitations.

Materials and Methods:

Twenty extracted human teeth with single-rooted canals were selected and divided into two groups: warm gutta-percha obturation and cold gutta-percha obturation. In the warm gutta-percha group, gutta-percha was heated to a predetermined temperature using a warm gutta-percha heating device and injected into the root canal using a heated carrier. In the cold gutta-percha group, gutta-percha was applied directly to the root canal without prior heating. Root canal obturation quality was assessed using radiographic imaging to evaluate the presence of voids, completeness of obturation, and adaptation to the canal walls. Micro-computed tomography (micro-CT) analysis was also performed to quantify the volume of obturating material and assess the three-dimensional distribution of gutta-percha within the root canal space.

Results:

Both warm and cold gutta-percha techniques demonstrated effective obturation of root canals, with comparable outcomes in terms of void formation, completeness of obturation, and adaptation to canal walls. However, micro-CT analysis revealed differences in the volume and distribution of gutta-percha within the root canal space. Warm gutta-percha obturation exhibited more uniform distribution of gutta-percha material and higher volumetric filling compared to cold gutta-percha obturation. Additionally, the warm gutta-percha technique demonstrated superior flowability and adaptation to irregularities within the root canal system.

Conclusion:

In this in vitro study, warm gutta-percha obturation demonstrated advantages over cold gutta-percha obturation in terms of volumetric filling, distribution within the root canal space, and adaptation to canal irregularities.
Neuro-Behçet’s presentation as cerebral venous thrombosis – A report of two cases and review of the literature
Authors: Gupta M , Rao VB , Ramakrishnan S , Kulkarni GB
Published: July 2024

Cerebral venous thrombosis (CVT) is a rare stroke with multiple risk factors. One rare risk factor is Behçet’s disease (BD). Out of around 3000 cases at our center in the past 10 years, two cases of BD with CVT were seen. Herein, we report on their clinical symptoms, course, and management. Case 1 was a 18-year-old girl with a history of recurrent skin lesions presenting with encephalopathy syndrome due to CVT, requiring decompression. Despite our best efforts, she developed complications and expired due to sepsis. Case 2 was a 22-year-old male with raised intracranial pressure syndrome and a history of recurrent orogenital ulcers. His evaluation showed retinal vasculitis, papilledema, and bilateral lateral rectus palsy. Both had CVT on neuroimaging and had positivity for human leukocyte antigen-B51. Case 2 responded to the anticoagulation and immunomodulation. Risk factor identification is essential in managing CVT, and planned evaluation (clinical or investigations) plays an important role in identifying rare causes that need specific treatment.
Attitude and Practice of General Dentists and Specialists about Restoration of Root-Canal Treated Teeth in Southern Saudi Arabia: A Cross-Sectional Survey
Authors: Alghamdi Nuha S.
Published: July 2024

Background:

Due to tooth structure loss from caries, trauma, fracture, prior restorations, and endodontic therapy, all of which lower the tooth’s fracture resistance, restoring teeth that have had endodontic therapy presents a number of challenges. To evaluate the attitude and practice of dentists and specialists in Southern Saudi Arabia regarding the restoration of endodontically treated teeth.

Materials and Methods:

A cross-sectional questionnaire-based study was carried out in Southern Saudi Arabia with a sample of general dentists as well as dental specialists. The questionnaire consisted of 12 items (questions), of which the first few inquired about participants’ demographic data such as age, years of practice, and the rest of the questions were intended to ask regarding their choice and use of restorative options of endodontically treated teeth. Data hence obtained were subjected to statistical analysis using SPSS version 20.

Results:

A majority of the study dentists (33.8%) prefer tooth-colored crowns to use for endodontically treated anterior teeth when more than 50% of the tooth structure is remaining. Nearly 29.7% believed to use of prefabricated post and tooth-colored crowns for endodontically treated anterior teeth when <50% of the tooth structure is remaining. Most of the study participants (75.7%) preferred composite core material and (64.9%) placed the “post” after waiting for 1 week. It was observed that the majority of the specialists used prefabricated post and tooth-colored crown (29.3%) as a restorative material for endodontically treated anterior teeth when <50% of tooth structure was remaining. A statistically significant difference (P = 0.011*) was found between the responses of specialists and general dentists for their preferred restorative material post root canal treatment (RCT).

Conclusion:

The survey revealed a clear predisposition among respondents to tapered prefabricated metallic posts. This result demonstrates a consensus among dentists, indicating a preferred option for postdesign in their clinical practice. Different views were expressed by general dentists and specialists for the questions related to restoration options, depending on their choices.

Published: July 2024

Background:

Trichosporon species are pathogenic yeasts that colonize diverse human body sites and cause superficial in addition to invasive trichosporonosis, especially in immunosuppressed patients. The disease is an emerging health-care problem, as it has shown a noticeable increase in recent years. The leading risk factors are antibiotic use, invasive medical equipment, and chemotherapy. Informed evidence on the disease and its causal agent is needed.

Objective:

Presentation of clinical cases caused by Trichosporon sp. and identification of isolates recovered from various specimens in Aseer Central Hospital setting.

Materials and Methods:

The study analyzed fungal cultures (n = 20) from different clinical specimens submitted on a routine basis from hospital wards for general microbiological investigation at Aseer Central Hospital, Abha, Saudi Arabia (2021–2023). Mycologically proven trichosporonosis cases were initially identified by desktop methods, automated Vitek 2, and confirmed by sequence analysis of the ribosomal targets, namely the large-subunit RNA gene (D1–D2 region) and internal transcribed spacers 1 and 2 (ITS1 and ITS2 regions), patients were treated with fluconazole, and treatment outcomes were recorded.

Results:

Clinical features and culture results confirmed trichosporonosis caused by Trichosporon asahii with different clinical presentations. The majority of the cases were urinary tract (44%), followed by skin (28%) and respiratory tract (12%). All trichosporonosis cases responded to fluconazole. The neighbor-joining phylogenetic tree based on the rRNA regions and ITS and comparative analysis using GenBank reference data showed the association of our strains to the reference T. asahii clade, closely related to T. faecale and T. insectorum but different from other species.

Conclusions:

The study offered accurate species identification of the Trichosporon isolates by routine phenotypic tests as well as sequence-based techniques. Urinary tract infections were the most common manifestation of the infection, followed by skin and then respiratory tract infections. The cases of trichosporonosis responded well to fluconazole treatment. T. asahii is possibly underreported and should be considered in routine diagnostic investigations, notably in nosocomial infections.
The pivotal role of microglia in injury and the prognosis of subarachnoid hemorrhage
Authors: Ning Wenjing , Lv Shi , Wang Qian , Xu Yuzhen
Published: July 2024

Subarachnoid hemorrhage leads to a series of pathological changes, including vascular spasm, cellular apoptosis, blood–brain barrier damage, cerebral edema, and white matter injury. Microglia, which are the key immune cells in the central nervous system, maintain homeostasis in the neural environment, support neurons, mediate apoptosis, participate in immune regulation, and have neuroprotective effects. Increasing evidence has shown that microglia play a pivotal role in the pathogenesis of subarachnoid hemorrhage and affect the process of injury and the prognosis of subarachnoid hemorrhage. Moreover, microglia play certain neuroprotective roles in the recovery phase of subarachnoid hemorrhage. Several approaches aimed at modulating microglia function are believed to attenuate subarachnoid hemorrhage injury. This provides new targets and ideas for the treatment of subarachnoid hemorrhage. However, an in-depth and comprehensive summary of the role of microglia after subarachnoid hemorrhage is still lacking. This review describes the activation of microglia after subarachnoid hemorrhage and their roles in the pathological processes of vasospasm, neuroinflammation, neuronal apoptosis, blood–brain barrier disruption, cerebral edema, and cerebral white matter lesions. It also discusses the neuroprotective roles of microglia during recovery from subarachnoid hemorrhage and therapeutic advances aimed at modulating microglial function after subarachnoid hemorrhage. Currently, microglia in subarachnoid hemorrhage are targeted with TLR inhibitors, nuclear factor-κB and STAT3 pathway inhibitors, glycine/tyrosine kinases, NLRP3 signaling pathway inhibitors, Gasdermin D inhibitors, vincristine receptor α receptor agonists, ferroptosis inhibitors, genetic modification techniques, stem cell therapies, and traditional Chinese medicine. However, most of these are still being evaluated at the laboratory stage. More clinical studies and data on subarachnoid hemorrhage are required to improve the treatment of subarachnoid hemorrhage.

Authors: Adekola Oyebola Olubodun , Oladimeji Motunrayo Adebukunola , Gabriel Kolawole Asiyanbi , Olanipekun Simeon Olafimihan
Published: July 2024

Background

Organophosphate poisoning is the commonest accidental and suicidal poisoning in developing countries like Nigeria. Respiratory distress, unconsciousness, and acute cholinergic crisis are reasons for critical care.

Objective

We determined the clinical presentation and outcome following sniper poisoning in critically ill patients.

Methods

This was a retrospective case series of 13 patients managed for sniper poisoning in a six-bed private intensive care unit in Lagos, Nigeria, from June 2016 to June 2022. The diagnosis of sniper poisoning was made based on a positive history of ingestion of sniper before presentation, and clinical signs of cholinergic hyperactivity.

Results

A total of 13 patients were reviewed, 3 females and 10 males with median age and APACHE II score of 23.5 years (IQR, 5.75, 27.75) and 26 (IQR, 24, 27.5), respectively. Deliberate ingestion of sniper occurred in 10 patients. Respiratory insufficiency/unconsciousness, and bradycardia/hypoxia occurred in 11 and 10 patients, respectively. The median duration of ICU admission was 6.5 days, (IQR: 4, 8). Intravenous atropine and glycopyrrolate were administered in 10 and 2 patients, respectively. The median dose of atropine on days 1, 2, and 3 were 38.9 mg, 27.6 mg and 18.5 mg, respectively. Mechanical ventilation was initiated in 10 patients, 8 of whom were discharged home. Out of 13 patients, 10 survived, while 3 died.

Conclusion

This case series showed that sniper poisoning is a life-threatening condition that requires immediate diagnosis and treatment. Early referral for critical care, initiation of atropine, and supportive mechanical ventilation can save lives.

Authors: Aboelmaaty Sara A. , Gomaa Ibrahim A. , Pachon Mauricio E. Perez , Rumer Kristen K.
Published: July 2024

Surgical abdominal emergencies among patients with cerebral palsy (CP) are infrequently reported. The most commonly reported reason for urgent and emergent abdominal surgery among patients with CP is intestinal volvulus. Intestinal volvulus leads to obstruction and vascular compromise, potentially resulting in life-threatening ischemia and necrosis. Volvulus typically presents with abdominal pain and decreased bowel function. When patients are nonverbal and have baseline bowel dysfunction, symptoms of volvulus can be difficult to diagnose. Here, we present a case of an adult female patient with CP who presented with ischemic colitis with perforation and underwent emergency total colectomy and end-ileostomy. Her postoperative course was complicated by two episodes of intestinal volvulus that occurred one and three months after the initial operation. At the second presentation, she had global bowel ischemia due to the volvulus, which led to her death. We have reviewed and summarized the current literature regarding abdominal emergencies among patients with CP.

Published: July 2024

In today’s digital era, most electrical gadgets have become smart, and the great majority of them can connect to the internet. The Internet of Things (IoT) refers to a network comprised of interconnected items. Cloud-based IoT infrastructures are vulnerable to Distributed Denial of Service (DDoS) attacks. Despite the fact that these devices may be accessed from anywhere, they are vulnerable to assault and compromise. DDoS attacks pose a significant threat to network security and operational integrity. DDoS assault in which infected botnets of networks hit the victim’s PC from several systems across the internet, is one of the most popular. In this paper, three prominent datasets: UNSW-NB 15, UNSW-2018 IoT Botnet and recent Edge IIoT are using in an Anomaly-based Intrusion Detection system(AIDS) to detect and mitigate DDoS attacks. AIDS employ machine learning methods and Deep Learning (DL) for attack mitigation. The suggested work employed different types of machine learning and Deep Learning (DL): Random Forest (RF), Support Vector Machine (SVM), Logistic Regression, and Multi-layer perceptron (MLP), deep Artificial Neural Network (ANN), and Long Term Short Memory (LSTM) methods to identify DDoS attacks. Both of these methods are contrasted by the fact that the database stores the trained signatures. As a results, RF shows a promising performance with 100% accuracy and a minimum false positive on testing both datasets UNSW-NB 15 and UNSW-2018 Botnet. In addition, the results for a realistic Edge IIoT dataset show a good performance in accuracy for RF 98.79% and for deep learning LSTM with 99.36% in minimum time compared with other results for multi-class detection.
Cones of traces arising from AF $C^{*}$-algebras
Authors: Moodie Mark , Robert Leonel
Published: July 2024

We characterize the topological non-cancellative cones that can be expressed as projective limits of finite powers of

[0,\infty]

. For metrizable cones, these are also the cones of lower semicontinuous extended-valued traces on approximately finite-dimensional (AF)

C^{*}

-algebras. Our main result may be regarded as a generalization of the fact that any Choquet simplex is a projective limit of finite-dimensional simplices. To obtain our main result, we first establish a duality between certain non-cancellative topological cones and Cuntz semigroups with real multiplication. This duality extends the duality between compact convex sets and complete order unit vector spaces to a non-cancellative setting.
Integration System of Phase-Locked Loop Imaging and Dots Centroid
Tracking Methods for Tire Deformation Measurement during Rolling
Authors: Matsubara Masami , Shibataka Seiki , Tachiya Hiroshi , Kawamura Shozo , Tajiri Daiki , Shibuya Akira , Higuchi Masahiro
Published: July 2024

This study develops an image measurement system that accurately measures rotating
tires’ deformed shape. Noncontact image measurement presents challenges such as
difficulty in achieving a high sampling frequency and high pixel count, and
achieving high resolution in feature point tracking as a subset in image
processing because of the curvature, expansion, and contraction of the tire
sidewall. The shape of the sidewall affects the mechanical properties of the
tire, and the deformation shape during actual operation provides important
information for tire design. In this study, a system integrating phase-locked
loop imaging, dot centroid tracking (DCT), and stereo methods is used to achieve
high-resolution measurements of tire deformation shapes. In particular, the DCT
method typically improves the accuracy of tracking by setting the markers in
black and the background in white and ignoring imaging noise from the background
with white halation depending on the amount of light. 3D measurements under
static conditions were conducted to validate the proposed system. Consequently,
the system was confirmed to be capable of capturing the differences in the
sidewall deformation depending on the test conditions, and the validity of the
system was confirmed.

Published: July 2024

El objetivo de este estudio es construir, estructurar y validar psicométricamente el Barómetro de Salario Emocional para Pymes (BASE-PYMES) basado en un modelo teórico de dos factores (causales y consecuentes) y una serie de dimensiones y subdimensiones que contienen una batería de reactivos que se miden en dos tipos de escalas (Likert y diferencial semántico), ambas puntuadas de 1 a 7. La validez de contenido, medida con V de Aiken, confirma, el 92,05% de acuerdo entre jueces respecto de los criterios claridad, objetividad y coherencia. El pilotaje arroja adecuados niveles de consistencia interna con valores α entre 0,81 y 0,93 y correlación ítem test corregida entre 0,47 y 0,84. Se aplicó a 385 colaboradores de pymes, cuyas respuestas permitieron realizar análisis discriminante mediante la prueba t-student (t) y análisis factorial exploratorio (AFE) (extracción de componentes principales y rotación varimax). La prueba t revela que existen diferencias significativas entre las puntuaciones del Grupo A (directivos) y el Grupo B (operativos); mientras que la adecuación del tamaño muestral sugiere la pertinencia del AFE (KMO=0,91, esfericidad de Bartlett significativa y matriz de correlación anti-imagen con valores entre 0,85 y 0,96). Las comunalidades fluctúan entre 0,62 y 0,85, emergiendo una estructura que confirma parcialmente el modelo propuesto que explica el 69,57% de la varianza. El BASE-PYMES se compone de 45 reactivos, distribuidos en 6 dimensiones y 10 subdimensiones, representando un aporte teórico, metodológico y práctico que contribuye con la mitigación de la escasa difusión del constructo y propone un instrumento para diagnosticar las valoraciones perceptuales respecto de las condiciones ambientales y laborales de las relaciones de trabajo, el estado psicosocial y el bienestar emocional de los colaboradores.

Es un estudio cuantitativo basado en una muestra de 275 micro y pequeñas empresas comerciales ubicadas en el Municipio de Ciudad Ixtepec, Oaxaca, México, considerado uno de los diez polos de desarrollo del Corredor Interoceánico del Istmo de Tehuantepec. Del total de directivos entrevistados, 78% son dueños y 22% son administradores; 38% tienen más de 50 años; 64% son mujeres; 38% concluyeron preparatoria. Los resultados del análisis de regresión logística muestran que la edad y sexo del gerente, la antigüedad de la empresa y las decisiones tomadas debido a la pandemia son las principales variables que permitieron diferenciar las decisiones de los gerentes versus los dueños de las empresas y que en ambos casos estuvieron orientadas a tratar de mantener su funcionamiento y continuidad. Se concluye que, la condición de propiedad en combinación con el género fueron las principales variables que determinaron la supervivencia de la micro y pequeña empresa del sector comercial en Ciudad Ixtepec, Oaxaca en la región del Corredor Interocéanico del Istmo de Tehuantepec durante el periodo de pandemia por Covid-19

Authors: Álvarez Sepúlveda Humberto Andrés , Silva Gallegos Valentina Alexandra
Published: July 2024

La narrativa histórica es una herramienta fundamental en la formación de los futuros profesores de historia porque permite evaluar el desarrollo de su pensamiento histórico. Este capítulo analiza la importancia de la narrativa histórica para evaluar el pensamiento histórico de los futuros profesores de historia y explica diferentes tipos de narrativas que puede utilizar el profesor formador para desarrollar dicha habilidad en el alumnado. Metodológicamente, este trabajo se apoya en una revisión de alcance de publicaciones alojadas en diferentes bases de datos (Latindex, Wos, Scopus, Scielo, Clacso, Redalyc, ProQuest y Dialnet). El análisis se realizó bajo el método inductivo, el paradigma humanista, con enfoque cualitativo, tipo interpretativo, y el diseño narrativo de tópico. Los resultados evidencian que la narrativa histórica es una evidencia relevante para comunicar perspectivas sobre el pasado y evaluar el pensamiento histórico. Por este motivo, se concluye que resulta fundamental aplicar este recurso en la formación docente.

Authors: Pavía González Georgette del Pilar
Published: July 2024

El tratamiento del error abordó su evolución histórica, tipologías propuestas por diversos autores y posturas relacionadas, además de conceptualizaciones sobre la corrección y su papel en el proceso de aprendizaje. Se exploran conceptos como la interlengua y análisis contrastivos, subrayando las complejidades de aprender una segunda lengua. Se destaca la necesidad de claridad en la metodología de adquisición del idioma, desde perspectivas pedagógicas hasta lingüísticas. Se presenta un marco teórico y estrategias de corrección sugeridas por estudios previos. Se sugiere que el aprendizaje puede verse afectado por implicaciones socioemocionales. Este análisis enfatiza la importancia de abordar el error no solo como una falla, sino como una oportunidad para mejorar y comprender mejor el proceso de aprendizaje de una lengua extranjera.
Caminando entre la complejidad y el buen vivir: saberes ancestrales andinos como alternativa transformadora frente a los desafíos de la modernidad
Authors: Valenzuela Morales Alejandro
Published: July 2024

Este capítulo examina el concepto de Buen Vivir (Sumak Kawsay), una filosofía ancestral andina centrada en la coexistencia armónica con la naturaleza y la comunidad, en diálogo con las Teorías de la Complejidad. Se propone un análisis de cómo estos enfoques, al entrelazarse, constituyen una alternativa transformadora a las visiones modernas de desarrollo. El texto presenta la perspectiva del Buen Vivir como un paradigma holístico que cuestiona la fragmentación de la vida humana en compartimentos aislados, mientras que las Teorías de la Complejidad ofrecen un marco teórico para comprender las interconexiones e interdependencias de los sistemas sociales y naturales. A lo largo del texto, se expone cómo la combinación de ambos enfoques podría influir significativamente en la educación, la formulación de políticas y la gestión de desafíos contemporáneos. Se destaca cómo los principios de reciprocidad, equilibrio y sostenibilidad inherentes al Sumak Kawsay se complementan con los conceptos de no linealidad, adaptabilidad e incertidumbre que caracterizan las Teorías de la Complejidad. Se incluyen ejemplos prácticos para ilustrar el potencial de esta simbiosis teórica en la educación y el desarrollo sostenible, sugiriendo que su integración puede ofrecer valiosas orientaciones para los retos del siglo XXI. El capítulo proporciona una visión inspiradora sobre cómo los saberes ancestrales andinos, combinados con el pensamiento complejo, pueden trazar un camino hacia un futuro más inclusivo, equitativo y sostenible.

Authors: Miranda Escobar Ana Lucía
Published: July 2024

La educación de la sexualidad promovida en los distintos países de América Latina ha atravesado grandes cambios en la última década. En este proceso, las representaciones docentes, entendidas a nivel de sus discursos y prácticas, así como de sus creencias y conocimientos, se han convertido tanto en una evidencia del estado de la educación sexual como en una posibilidad para su transformación. Así, en esta revisión sistemática de literatura, se analizaron 37 estudios empíricos realizados entre los años 2010 y 2023 con el fin de profundizar en las representaciones docentes y resaltar el desarrollo teórico logrado por la investigación educativa respecto a los fines y objetivos de la educación sexual; los modelos y contenidos predominantes; el papel de los distintos actores educativos. Además, se identificaron los marcos interpretativos desde los cuales se piensa la educación sexual y se formulan nuevos programas de enseñanza, así como las autoras representativas cuyo trabajo ha sido clave para la promoción de una sexualidad sana, respetuosa y responsable, en las escuelas de nuestra región.

Significantly higher requirements regarding traffic safety are placed on the most complex objects on the road network, such as road tunnels. On the territory of the Republic of Serbia in 2023, traffic safety inspections in tunnels (RSI) were carried out on IA state roads. In addition to the usual phases and steps carried out when performing RSI on rural sections, RSI in tunnels is more complex compared to the usual methodological procedure for other roads. Multidisciplinary, comprehensive, detailed, and extensive analyses of various elements were carried out by a multidisciplinary team that properly analyzed all aspects of the system's functioning and traffic safety in the tunnels. The conducted traffic safety checks are important for improving traffic safety in tunnels, given that there is a trend of building new tunnel objects in the Republic of Serbia.
