Authors: Souilah Aziz , Kessouri Oussama 
Published: November 2024

Abstract

Introduction.
Soccer is a demanding sport that requires rapid and explosive movements. Enhancing speed and power is crucial for optimal performance in soccer players. Two training methods, Speed, Agility, and Quickness (SAQ) training and Small-Sided Games (SSG) training, are commonly used to improve these physical attributes. This study aimed to compare the effects of SAQ training versus SSG training on performance measures in young soccer players.

Material and Methods.
Twenty-four soccer players were randomly assigned to either an SAQ training group (n = 12) or an SSG training group (n = 12). An 8-week training program was implemented, and pre- and post-training assessments included 10-m and 20-m sprint tests, Zigzag Change of Direction Speed (CODS), Repeated Sprint Ability, Squat Jump (SJ), Counter-movement Jump tests. Statistical analysis involved paired t-tests to compare pre- and post-test results within groups and ANOVA to examine interactions between time and group effects.

Results.
SAQ and SSG training groups showed significant improvements across all measures (all p < 0.05). Time effects were significant (all p < 0.05), indicating overall effectiveness, with small time x group interactions (all p < 0.05; η2 ranging from 0.001 to 0.055). However, the percentages indicated a slight advantage for SAQ training in 10- and 20-meter speed and SJ, as well as for SSG training in RSAmean.

Conclusions.
Both SAQ and SSG training programs effectively enhance speed and power performance in young soccer players. Selection between programs can align with specific training goals, highlighting potential for further optimization in athletic development.

Published: November 2024

Abstract
Efficient urban facility access is crucial for enhancing residents’ well-being and quality of life. This study examines public transport accessibility to essential facilities in Rome, such as high schools and hospitals, using gravity models based on open data sources, like OpenStreetMap and GTFS. Two versions of the gravity model are compared: an origin constrained and a doubly constrained. The latter can consider the capacity of facilities as a strict constraint, offering thus a more realistic assessment of accessibility. The findings highlight the correlation of public transport quality and urban accessibility, showing how variations in public transport supply affect the weighted average time to reach services like healthcare, education, and leisure. This approach reveals specific zones needing improvement and provides a valuable tool for predicting the impact of future changes in the transport network with respect to social equity. An online platform has been developed to allow a readily available application of this methodology to boost active citizenship and proactive decision making.

Published: November 2024

Abstract
The need to decarbonise and reduce pollutant emissions from maritime transport is facilitating the studies of ground effect vehicles. Technical development in recent decade concerning unmanned flights in drones has supported this development. These vehicles could have much higher speed than sea vessels and they are estimated to be less costly compared to air transport. Unmanned operations without passengers enable wider range of transport connections (even in difficult conditions). In this research we analyse prototype vehicle called Airship and its possible use in different routes of intra Canary Islands’ transport. We suggest the most lucrative routes and cargo groups. Initial cost and revenue considerations are made over the life-cycle of Airship. As a result, we can point that there are three main factors determine the success of the transport operations. They are: the number of journeys per day, business days operating per year and freight price.

Authors: Limcharoen Natthaya , Thiradilok Sasipa , Thanathornwong Bhornsawan , Manopatanakul Somchai 
Published: November 2024

Objectives:
This study aimed to develop a clinical decision support system utilizing the MKG angle – derived from points M, K, and G – as a novel neural network parameter for evaluating sagittal maxillo-mandibular discrepancy. This system serves as a pre-operative screening tool for predicting the need for orthognathic surgery.

Material and Methods:
This retrospective study collected 494 digital lateral cephalograms. MKG angle values extracted from these cephalograms were analyzed using a Keypoint Region-based Convolutional Neural Network integrated with Detectron2 for object detection. Analysis was conducted using Keras software to facilitate decision-making regarding orthognathic surgery. The model’s output ranged from 0 to 1, with values closer to 1 indicating a stronger recommendation for orthognathic surgery. A training loss graph was used to monitor the model’s performance over epochs, while a confusion matrix evaluated the model’s accuracy and predictive capabilities.

Results:
The training loss value for the object detection model was 3.0510. Model performance was further evaluated using metrics such as root mean square error (RMSE) and percentage of detected joints (PDJ). The RMSE was measured at 2.68 pixels, while the PDJ, with a threshold of 0.05, achieved a value of 0.99, indicating a high level of accuracy. The developed system achieved an orthognathic surgery diagnosis accuracy of 70.41%, with a training loss value of 0.6163. The evaluation revealed instances of misdiagnosis; out of 98 cases, 29 were identified as misdiagnosed through a confusion matrix. The model’s sensitivity and specificity were measured at 72.5% and 68.97%, respectively.

Conclusion:
A supplementary tool for orthognathic screening, utilizing two-dimensional digital lateral cephalometry images and MKG angle as a parameter, was developed by merging a neural network model with clinical decision-making.

Authors: Lal Alizadeh Farzaneh , Abtahi Mostafa , Sekandari Fateme , Kahnemuee Fatemeh 
Published: November 2024

Objectives:
Sleep-related breathing disorders (SRBDs) are a group of pathological conditions characterized by dysfunction in the upper airways, ranging from primary snoring to obstructive sleep apnea. The purpose of this study is to determine the prevalence of SRBD using the SRDB Scale of the Pediatric Sleep Questionnaire (SRBDPSQ) among children and adolescents with class II malocclusion and mandibular deficiency. In addition, it seeks to identify any correlations between SRBD and the mentioned malocclusion.

Material and Methods:
A census was conducted among potential candidates for mandibular advancement treatment who were referred to the orthodontic ward of Mashhad Dental School. The parents of 90 children aged 7 to 14 completed the Persian version of the SRBD-PSQ after clinical examination and confirmation of the need for mandibular advancement by an orthodontist.

Results:
Ninety questionnaires were collected for the study, with 37.8% being boys and 62.2% being girls. The overall prevalence of SRBD was found to be 15.6%. During the general examination, the questionnaire’s total score and behavioral differences were significantly higher in boys (P = 0.001, P = 0.004, respectively). Age displayed an inverse and significant relationship with behavioral disorders and SRBD (P = 0.023, P = 0.031, respectively), indicating a decrease in SRBD and behavioral disorders with increasing age. Individuals who answered positively to the questionnaire had significantly higher rates of snoring (P = 0.025) and behavioral disorders (P < 0.001) compared to others.

Conclusion:
SRDBs are more prevalent among children who meet the criteria for mandibular advancement treatment compared to the general population of children. Boys with attention deficit hyperactivity disorder require special attention. Snoring and behavioral disorders are key symptoms for diagnosing SRBD.

Authors: Kuppusamy Dheebika , Nanda Nivedita , Delhi Kumar Chinnaiah Govindareddy , Vinod Kolar Vishwanath , Mandal Amit Kumar , Kar Rakhee 
Published: November 2024

Objectives:
Hemoglobin E and S (HbE and HbS) are the most common hemoglobin (Hb) variants widely spread across the Asian continent that differ from the normal adult Hb in a single amino acid in the β-globin gene. The aim of this study was to explore if this change in globin structure has any effect in the function of Hb in terms of its oxygen affinity.

Material and Methods:
The oxygen dissociation curve (ODC) describes the relationship between the partial pressure of oxygen (pO2) and oxygen saturation of hemoglobin (sO2). ODC was plotted based on pO2 and sO2 values obtained on bubbling buffered oxygen and nitrogen gases through reconstituted variant Hb mixture samples in an experimental setup.

Results:
The p50 values of fetal hemoglobin (HbF), HbA, HbE, Sbeta, and HbS were found to be 20 ± 2 mmHg, 28.01 ± 2.5 mmHg, 33 ± 1.5 mmHg, 38 ± 2 mmHg, and 40± 0.6 mmHg at a pH of 7–7.5 and ambient temperature of 25°C, respectively.

Conclusion:
HbF had greater oxygen affinity while HbE and HbS showed a decreased oxygen affinity, more pronounced with HbS, possibly due to shift in the equilibrium toward the deoxy form. Even though the clinical implication may be variable, these findings reflect that there could be an interplay between Hb variants and oxygen affinity.
