Les jeunes exilés face au ralentissement institutionnel
Authors: Perrot Adeline
Published: October 2021

Depuis les années 1990-2000, en France, des mesures d’accompagnement éducatif se sont développées à destination de jeunes exilés. Elles reposent sur l’appréciation de l’âge et l’attribution du statut de « mineurs non accompagnés » (MNA) au moyen d’une série d’opérations de jugement (évaluation sociale, analyse documentaire et expertise médicolégale), conduites par les autorités administratives et judiciaires. Une fois reconnus « mineurs en danger et à protéger », les jeunes exilés connaissent un ensemble de modes d’accueil temporaires (mise à l’abri, accueil provisoire) qui produisent des effets de freinage avant la scolarisation et le placement définitif à l’Aide sociale à l’enfance (ASE). Ces ralentissements institutionnels se manifestent par le prolongement des délais d’attente liés aux examens d’âge et d’isolement, aux orientations scolaires et éducatives, alors même que les MNA ont à remplir tous les critères de régularisation administrative avant 18 ans. Face à cette logique d’urgence, l’article explore la dimension relationnelle des rapports aux temporalités en donnant à voir les tentatives d’ajustements individuels et collectifs.
Enquêtes statistiques et approches intersectionnelles
Authors: Hagège Meoïn , Condon Stéphanie
Published: October 2021

L’un des défis scientifiques dans les études des violences de genre reste le degré de prise en compte de l’intersectionnalité dans l’enquête par questionnaires et de ses données. Dans le cas de l’enquête Virage ( Violence et rapports de genre ) dans les Outre-mer (2018), la simple réplication ou le prolongement de l’enquête hexagonale du même nom (2015) à trois départements-régions supplémentaires n’est pas approprié pour adéquatement y décrire le phénomène des violences de genre. L’analyse critique de l’enquête « en train de se faire » propose des pistes de réflexion pour répondre à ce problème méthodologique et prendre en compte les rapports sociaux liés au genre et à la classe sociale, mais aussi ceux liés à la racialisation, et aux rapports entre « métropole » et territoires ultramarins – et ce, aux trois premiers stades de l’enquête : sa conception, sa mise en œuvre et son recueil de données.

Published: October 2021

In this article, we investigate new results of existence and uniqueness for systems of nonlinear coupled differential equations and inclusions involving Caputo-type sequential derivatives of fractional order and along with new kinds of coupled discrete (multi-points) and fractional integral (Riemann-Liouville) boundary conditions. Our investigation is mainly based on the theorems of Schaefer, Banach, Covitz-Nadler, and nonlinear alternatives for Kakutani. The validity of the obtained results is demonstrated by numerical examples.
Access to sanitary toilets and health outcomes: A panel data analysis using two-way fixed effects model
Authors: Zhou Wanli ,   School of Public Administration, Zhongnan University of Economics and Law, Wuhan 430073, P.R. China, Gu Yingwen , Wang Xiulin
Published: October 2021

Based on the data regarding the renovation of the toilets of 30 provinces (municipalities) in rural China from 2005 to 2017, this study utilized a two-way fixed effect model to empirically test the impact of access to sanitary toilets on health, which include intestinal infectious diseases (consisting of hepatitis A, dysentery, and typhoid) and child mortality (consisting of perinatal mortality, infant mortality, and the mortality rate of children under 5). This study attempted to assess the health outcomes of the "toilet revolution" in rural China. The results showed that: (1) Access to sanitary toilets effectively reduced the incidence of hepatitis A and dysentery. For every 1% increase in the rate of access to sanitary toilets, the incidence of hepatitis A was reduced by 5.6%, and the incidence of dysentery was reduced by 36.5%. (2) Access to sanitary toilets does not significantly reduce child mortality. (3) There are obviously regional differences in the impact of access to sanitary toilets on the health outcomes. The renovation of sanitary toilets has shown the most significant effect on reducing the incidence of intestinal infectious diseases in the central region as well as the effect on reducing child mortality in the western region. It is implied that the health outcomes of China's "toilet revolution" may provide supporting evidence and experience for other developing countries and regions in implementing toilet renovation projects.
De la célébration artistique au trouble émotionnel : les représentations discursives de Florence dans les récits des écrivains-voyageurs
Authors: Farina Annick , Sini Lorella
Published: October 2021

Cette étude est basée sur un sous-corpus de langue française tiré du Lessico dei Beni Culturali (Université de Florence), recueillant des récits d’écrivains-voyageurs francophones (du 16e au 21e siècle) ayant Florence, berceau du Rinascimento, comme toile de fond. Nous analysons ici tout d’abord les différentes dénominations qui contribuent à la construction discursive de ce « haut-lieu » (dénominations topographiques, chrononymes, intitulation d’œuvres). Dans un second temps, ce sont les représentations stéréotypées à partir de la valeur de « beauté » attribuée aux œuvres d’art et aux monuments florentins qui font l’objet de nos remarques. Enfin, nous tentons de cerner les modalités discursives qui ont pour fonction de « désacraliser » ces œuvres, une désacralisation qui s’exprime de manière saisissante dans le « syndrome de Stendhal », un trouble émotionnel aux caractéristiques discursives oxymoriques (ethos et pathos).
Le Verduron, un établissement gaulois aux portes de Marseille grecque
Authors: Bernard Loup
Published: October 2021

Établissement de la Celtique méditerranéenne situé aux portes de Marseille grecque, l’oppidum du Verduron a connu une phase de vie très brève, d’à peine une vingtaine d’années. Les Grecs le détruisent aux alentours de 200 av. J.-C. pour ne pas laisser à leurs marges un ennemi potentiel. C’est ce que révèle l’ouvrage, qui présente l’état de nos connaissances sur cet habitat, exploré partiellement au début du XXe siècle par un sculpteur marseillais puis intégralement fouillé par l’auteur. Grâce à la conservation exceptionnelle des vestiges, l’étude nous livre un lot de mobilier céramique particulièrement cohérent qui correspond à un laps de temps fort bref, et qui servira de référence pour les nombreux autres sites détruits à cette même époque sur les rivages de la Méditerranée. L’étude du mobilier métallique réalisée par l’archéologue Benjamin Girard met en avant l’importance des porteurs d’armes laténiens sur le site. L’étude architecturale menée avec l’architecte Alain Badie permet de mieux comprendre les modalités d’implantation et de construction des sites perchés des Celtes méditerranéens à la charnière du IIIe et du IIe s. av. J.-C. Enfin, l’analyse du site dans un contexte plus large permet de proposer de nouvelles interprétations pour comprendre les relations conflictuelles entre Grecs et Romains, et le début de la structuration des sociétés celtiques du deuxième âge du Fer.
L’hydraulicité des mortiers antiques, entre préconçus et réalité : l’exemple des mortiers de tuileau et autres matériaux de Gaule romaine
Authors: Coutelas Arnaud
Published: October 2021

Vitruve, dans ses écrits, évoque uniquement les pouzzolanes lorsqu’ il discourt sur la question des mortiers hydrauliques. Or, l’observation des maçonneries et revêtements antiques liés aux structures hydrauliques montre, dans la majeure partie des provinces romaines, l’utilisation systématique du tuileau. Celui-ci, globalement, possède effectivement des propriétés qui nous permettent de dire qu’il s’agit bien d’une pouzzolane artificielle. De fait aujourd’hui, pour la période Romaine, la présence du mortier de tuileau est devenue synonyme de la présence d’une structure hydraulique. Le mortier de tuileau est ainsi devenu synonyme de mortier hydraulique, puis de mortier d’étanchéité, voire étanche. Enfin, parfois, tout mortier rose est supposé mortier de tuileau, et donc mortier hydraulique… En prenant exemple sur quelques cas de la ville antique d’Arles et d’autres sites de Gaule romaine, il est possible d’affirmer que les mortiers de tuileau ont été utilisés ailleurs que dans le domaine de l ’hydraulique et que la qualité première de ces matériaux était une meilleure résistance mécanique, ainsi qu’une plus grande durabilité. Il apparaît aussi que des matériaux réalisés avec des granulats supposés inertes ont pu aussi développer des composés hydrauliques. Tout ceci nous permet de discuter le concept même de « mortier hydraulique ».
Searching for Water in the Sanctuaries of the Western Hills of Athens
Authors: Dakoura-Vogiatzoglou Olga , Dourou Maria
Published: October 2021

The two major demes of ancient Athens, Melite and Koile, were located on the three rocky hills of the Muses (Mouseion), of the Nymphs, and the Pnyx, west of the Acropolis. Excavations have revealed wells and cisterns as well as extensive water supply systems that show, from the Archaic period until Late Antiquity, how concerned the inhabitants were to preserve that invaluable element. Here we discuss archeological research on the presence of water in the known sanctuaries of the Western Hills. On the Hill of the Muses, the evidence may indicate the existence of a sanctuary of the Muses, most of its traces now covered by the Philopappos Monument. The clear presence of water in the nearby heroon-sanctuary of Mousaios may be associated with Orphic rituals. On the Pnyx a well-shaft outside the roadside shrine near the Dipylon Above the Gates may be associated with a sanctuary, while the Kallirrhoe cave-complex is well supplied with water. In contrast, no signs of a water system were found in the known Sanctuary of Zeus Hypsistos, in an unidentified shrine on the upper terrace of the hill, or even in the Sanctuary of Pan and the Nymphs. In the ancient sanctuaries on the Hill of the Nymphs, particularly the Sanctuary of Zeus, cisterns and channels reward careful study. And atop that hill, though water features are limited and difficult to read, it appears that a sanctuary of the nymphs long thrived. This assessment makes clear that wells and channels were vital parts of the sanctuaries, enabling us to connect the use of water with the sanctuaries’ religious rituals and practical needs.

Pour une lecture éco-poétique de Boum et Dog
Authors: Brodziak Sylvie
Published: October 2021

L’étude de Boum et Dog pour le projet mené à l’ITEM sur l’œuvre de René Maran s’accomplissant dans une société fortement préoccupée par les questions environnementales invite immédiatement à passer cette nouvelle par le tamis de la critique éco-poétique. Il s’agit donc de voir dans un premier temps si ce texte liminaire résiste à cette grille d’analyse afin de pouvoir l’étendre plus tard au recueil Bêtes de la brousse.
René Maran à Maurice Barrès : d’un « écrivain français » à l’autre
Authors: Luce Xavier
Published: October 2021

Les lettres adressées à Maurice Barrès au cours des années précédant la parution de Batouala, véritable roman nègre entre 1917 et 1920 offrent un éclairage sur l’intention et la mise en scène auctoriale de René Maran. Il semble en effet que l’écriture obéisse chez lui à un impératif ontologique, à savoir démontrer que « les nègres » sont des hommes comme les autres. L’auteur d’Un homme pareil aux autres se met ainsi en scène comme un exemple et un ambassadeur de la « cause » des nègres en tant que ceux-ci seraient des « êtres perfectibles ». La lecture de ces lettres permet d’apprécier le sens de son « métier d’écrivain français » dans la « lutte antiraciste » qu’il a pu mener au sein de la Ligue universelle de défense de la race nègre (LUDRN). Cet engagement peut se comprendre à l’aune d’une négritude en tant qu’elle est une « pratique sans théorie » (Roger Toumson) élaborée en fonction des « questions que pose la présence des Nègres au monde » et de « sa perception par l’Autre et par soi-même » (Romuald Fonkoua).
Interaction of Internet Addiction with FoMO
Authors: Bekman Müge
Published: October 2021

This study shows that digital media increases internet addiction and FoMO due to the impact of digitalization. As digitalization expands day by day and becomes a platform that can be addressed in its needs such as socialization, people's dependence on the internet is also increasing. Currently, digitalization also uses digital citizenship and digital identity as auxiliary elements. Without digital citizenship and digital identity, the impact of digitalization will also decrease. Digital citizenship and digital identity separate people from the normal and physical world and involve them in the digital plane. In this process, internet addiction is exposed due to the need to socialize, and individuals become even more dependent for socializing reasons. FoMO, on the other hand, is another indicator that addiction is growing. FoMO is increasing digital needs as there is a fear of missing out on the processes that are happening. As a result, internet addiction and FoMO are directly proportional to the increase in digital citizenship and digital identity.
A Sentiment Analysis and Role of Twitter for Health Communications
Authors: Çiçek Erkan , Gündüz Uğur
Published: October 2021

Social media has been in our lives so much lately that it is an undeniable fact that global pandemics, which constitute an important part of our lives, are also affected by these networks and that they exist in these networks and share the users. The purpose of making this hashtag analysis is to reveal the difference in discourse and language while analyzing Twitter data and to evaluate the effects of a global pandemic crisis on language, message, and crisis management with social media data. This form of analysis is typically completed through amassing textual content data then investigating the “sentiment” conveyed. Within the scope of the study, 11,300 Twitter messages posted with the #stayhome hashtag between 30 May 2020 and 6 June 2020 were examined. The impact and reliability of social media in disaster management could be questioned by carrying out a content analysis based totally on the semantic analysis of the messages given on the Twitter posts with the phrases and frequencies used.
Hate Speech on Social Media
Authors: Algül And , Akpınar Mustafa Eren
Published: October 2021

Based on the content that users prefer to follow, they are presented with similar content, which they may like. Thus, they can interact with individuals whose mindsets are similar to theirs. The users who cannot socialize in real life due to the COVID-19 pandemic and thus consider social media as an escape point think that they can produce unlimited and uncontrolled hatred in a synergistic environment consisting of people who produce similar contents to what they produce. This study focuses on hate speech on social media and analyzes the hate, discriminative, and derogatory speech regarding men within the “dunyaerkeklergunu” hashtag on Twitter based on symbolic interaction theory using the content analysis method. Within the scope of the “dunyaerkeklergunu” hashtag, 500 shares were analyzed. The study aims to raise awareness of the fact that hate speech can be made even on international men's day and that hate speech is not only directed towards women but is also made regarding men.

The Impact of Awareness Regarding Environmental Protection Laws on Ecological Degradation
Authors: Bamrara Atul
Published: October 2021

Global environmental troubles are gaining significance because of the speedy and antagonistic speed of urbanization. Environmental degradation restricts the flow of environmental services. Dumping of pollutants in excess of its assimilative capacity into air, water, and soil results in deterioration of the quality of these vital resources. The nature of environmental problem depends upon the level of economic development and the geographical condition of the area under consideration. India being a developing economy with a low per capita income, high population density, agriculture-dependent labour force, and high percentage of rural areas, the problems here are different from those in developed countries. The chapter highlights the impact of knowledge regarding environmental protection issues on environmental degradation.

Authors: Ibrahim Adamkolo Mohammed , Abba-Aji Nassir Mohammed , Vi Phuong Thi
Published: October 2021

Nigeria is one of the world's most vulnerable countries to extreme weather conditions and natural disasters linked to climate change, the impacts of which are exacerbated by rapid population growth, a fragile economy, high dependence on rain-fed agribusiness, and the country's weak adaptive capacity. The lack of or poor application of environmental communication in a strategic approach is critical to all of these. Using a thematic conceptual review of existing literature, this chapter shows that strategic environmental communication can be applied more easily to mitigate the impacts of climate change and environmental degradation through the use of well-established communication strategies and instruments to save the environment for socio-economic development.
Fostering Circular Economy in Urban Areas
Authors: Aktaş K. Orkun , Aktaş Can B.
Published: October 2021

The 21st century is an urban world. Strategies that aim to tackle the urban material challenge and promote circular economy are necessary to achieve sustainable development. Having established the importance of circular economy towards sustainable development, this study presents applicable strategies to reduce consumption and promote circularity specifically in urban centers. Main strategies may be categorized into three areas: reducing material use through better design, efficient manufacturing and processing, and more intensive recycling. For materials use reduction, dematerialization, appropriate design based on product service lifetime, design for X principles and extended producer responsibility are identified as prominent design approaches or policies. For effective manufacturing and processing, the implementation of best available technologies and additive manufacturing were identified to have potential significant impact. For end-of-life phase management, differences between upcycling, recycling, and downcycling require targeted industry-specific policies.

Sustainable Resilience in Urban Land Use
Authors: Vargas-Hernández José G. , Orozco-Quijano Elsa Patricia
Published: October 2021

Humanity is facing a series of important challenges, global warming being one the most important. Consequently, sustainability and resilience have become key elements in providing a better response to the crisis and in maintaining an equilibrium between ecology, economics, and various social domains. The design and use of urban land should consider the inclusion of a multi-functional green infrastructure to obtain different benefits, from ecosystem services to value creation. Additionally, the urban land-use planning system contributes to economic growth, social development, and environmental sustainability, while biodiversity is able to provide renewal and reorganization capacities for changes in social-ecosystems. All these elements bring forth a different paradigm for the future decisions of communities.

Authors: Pacheco-Pumaleque Liz , Pacheco-Pumaleque Alex , Vegas-Gallo Edwin A. , Pariona-Luque Rosario
Published: October 2021

Currently, working conditions have been evolving continuously, which makes it necessary to incorporate teleworking as a means of support to fulfill the tasks entrusted. However, this type of employment brings with it vulnerabilities within companies that are not prepared for such a situation. For this reason, a teleworking model is proposed to improve the management of information security in organizations in the commercial sector. This research is of a basic type with a non-experimental design and correlational level, with a quantitative approach, the survey technique, and a questionnaire was used as an instrument that was applied to 70 workers in the commerce sector. The results show that 54.29% consider the organizational change in companies as deficient, 62.86% indicate the use of technologies as deficient, and 84.29% consider that the level of confidentiality of the information is regular. These results reflect that information security management must be implemented to provide greater reliability, integrity, productivity, control, and protection to teleworking processes.
AI-Based Methods to Resolve Real-Time Scheduling for Embedded Systems
Authors: Boutekkouk Fateh
Published: October 2021

Artificial Intelligence is becoming more attractive to resolve nontrivial problems including the well known real time scheduling (RTS) problem for Embedded Systems (ES). The latter is considered as a hard multi-objective optimization problem because it must optimize at the same time three key conflictual objectives that are tasks deadlines guarantee, energy consumption reduction and reliability enhancement. In this paper, we firstly present the necessary background to well understand the problematic of RTS in the context of ES, then we present our enriched taxonomies for real time, energy and faults tolerance aware scheduling algorithms for ES. After that, we survey the most pertinent existing works of literature targeting the application of AI methods to resolve the RTS problem for ES notably Constraint Programming, Game theory, Machine learning, Fuzzy logic, Artificial Immune Systems, Cellular Automata, Evolutionary algorithms, Multi-agent Systems and Swarm Intelligence. We end this survey by a discussion putting the light on the main challenges and the future directions.

Published: October 2021

Motivated by the role that branded apps play in enhancing customer perceptions of brands, this paper is developed to provide a better understanding of the extent to which task-service fit associated with branded apps influences brand attitudes. The primary research objective is to determine how perceptions of task-service fit associated with branded apps enhances branded app experience and to explore brand co-creation and ultimately brand loyalty. Using data from 573 branded app users we were able to identify the following relationships: Perceptions of task-service fit and o-creation were found to influence brand loyalty. Also, task-service fit and randed app experience influenced co-creation. Finally, results also confirm that branded app experience and brand co-creation are mediators of the relationship between task-service fit and brand loyalty.

This framework can be used by any enterprise irrespective of the geography or country, vertical or domain, manufacturing or services.
Teaching-to-Learn
Authors: Rogers Melissa McConnell
Published: October 2021

Students report poor learning goals and study strategies. Educators may encourage better learning by requiring students to complete assessments that promote generative learning. The benefits of engaging in generative processes suggest encouraging them through teaching-to-learn assignments may be helpful. There is little research examining the benefits of teaching-to-learn conducted as part of a classroom curriculum with appropriate control conditions. The current study examines the benefits of teaching-to-learn on conceptual knowledge learning by requiring 53 students to prepare and deliver a lecture in one unit and write a paper in another unit. Students then answered questions covering their lecture and paper topics on both a unit and surprise final exam. Analyses on exams revealed students answered a greater percentage of the questions about their lecture topic correctly (84.91% and 76.23%) than their paper topic (76.98% and 67.92%) on both the unit and final exam respectively.
A Study of Optimized EEG Signal Induction/Extraction Techniques for Basic Motion Control of Personal Robots for Physically Impaired Users
Authors: Shin JeongHoon , Lee DongJun
Published: October 2021

When interfaces utilizing EEG signals are used, these signals can be induced through diverse association techniques. In the present article, differences in recognition performance of the systems related to robot control techniques according to diverse association techniques have been analyzed. For this purpose, elements that can affect the performance other than association techniques were excluded as much as possible, and the focus was placed on the performance analysis per association technique. According to the study results of the present article, the movement association technique based on gestures showed the highest recognition performance in the robot control system for multiple users. In the robot control system for single users, hearing-based phonation association is considered to show the highest recognition performance. In the study results of the present article, superior recognition performance is considered to be derived than the recognition performance displayed by existing systems when applied to the robot control area utilizing EEG signals.
IL-15 Trans-Presentation Is an Autonomous, Antigen-Independent Process

IL-15 plays a pivotal role in the long-term survival of T cells and immunological memory. Its receptor consists of three subunits (IL-15Rα, IL-2/15Rβ, and γc). IL-15 functions mainly via trans-presentation (TP), during which an APC expressing IL-15 bound to IL-15Rα presents the ligand to the βγc receptor-heterodimer on a neighboring T/NK cell. To date, no direct biophysical evidence for the intercellular assembly of the IL-15R heterotrimer exists. Ag presentation (AP), the initial step of T cell activation, is also based on APC–T cell interaction. We were compelled to ask whether AP has any effect on IL-15 TP or whether they are independent processes. In our human Raji B cell–Jurkat T cell model system, we monitored inter-/intracellular protein interactions upon formation of IL-15 TP and AP receptor complexes by Förster resonance energy transfer measurements. We detected enrichment of IL-15Rα and IL-2/15Rβ at the synapse and positive Förster resonance energy transfer efficiency if Raji cells were pretreated with IL-15, giving direct biophysical evidence for IL-15 TP. IL-15Rα and MHC class II interacted and translocated jointly to the immunological synapse when either ligand was present, whereas IL-2/15Rβ and CD3 moved independently of each other. IL-15 TP initiated STAT5 phosphorylation in Jurkat cells, which was not further enhanced by AP. Conversely, IL-15 treatment slightly attenuated Ag-induced phosphorylation of the CD3ζ chain. Our studies prove that in our model system, IL-15 TP and AP can occur independently, and although AP enhances IL-15R assembly, it has no significant effect on IL-15 signaling during TP. Thus, IL-15 TP can be considered an autonomous, Ag-independent process.
Zebrafish prmt2 Attenuates Antiviral Innate Immunity by Targeting traf6
Authors: Zhu Junji , Li Xiong , Sun Xueyi , Zhou Ziwen , Cai Xiaolian , Liu Xing , Wang Jing , Xiao Wuhan
Published: October 2021

TNFR-associated factor 6 (TRAF6) not only recruits TBK1/IKKε to MAVS upon virus infection but also catalyzes K63-linked polyubiquitination on substrate or itself, which is critical for NEMO-dependent and -independent TBK1/IKKε activation, leading to the production of type I IFNs. The regulation at the TRAF6 level could affect the activation of antiviral innate immunity. In this study, we demonstrate that zebrafish prmt2, a type I arginine methyltransferase, attenuates traf6-mediated antiviral response. Prmt2 binds to the C terminus of traf6 to catalyze arginine asymmetric dimethylation of traf6 at arginine 100, preventing its K63-linked autoubiquitination, which results in the suppression of traf6 activation. In addition, it seems that the N terminus of prmt2 competes with mavs for traf6 binding and prevents the recruitment of tbk1/ikkε to mavs. By zebrafish model, we show that loss of prmt2 promotes the survival ratio of zebrafish larvae after challenge with spring viremia of carp virus. Therefore, we reveal, to our knowledge, a novel function of prmt2 in the negative regulation of antiviral innate immunity by targeting traf6.
Djinnati syndrome as the first manifestation of temporal lobe epilepsy: A case report
Authors: Khosravi Mohsen
Published: October 2021

Culture-bound syndromes are a group of abnormal behavior patterns occurring only in definite cultural groups. As a form of culture-bound syndromes, possession trance is known as the “replacement of personal identity customary sense by a new identity.” Djinnati syndrome is a possession state restricted to specific areas of Iranian and Pakistani Baluchestan. Preceding studies suggested that complex behavioral manifestations of temporal lobe epilepsy (TLE) were likely to contain dissociative states symptoms. Nonetheless, people in numerous developing countries hold a belief that Jinn possession causes epilepsy even in quite well-educated people. The aims of the present report are to describe a patient who presented Djinnati syndrome as the very first manifestation of TLE and address the feasible detrimental impacts of cultural misconceptions on diagnosing and treating epileptic seizures.
Cone-beam computed tomography evaluation of prevalence and location of mandibular incisive canal in patients attending King Saud University Dental Hospital
Authors: Alshamrani Amal S. , Tokhtah Razan A. , Al-Omar Ahmad
Published: October 2021

OBJECTIVE:

This study aims to facilitate a surgeon's preoperative assessment by detecting the prevalence, location, and course of the mandibular incisive canal (MIC) in our population.

METHODOLOGY:

A retrospective study was conducted at King Saud University, Riyadh, Saudi Arabia. A total of 93 cone-beam computed tomography (CBCT) scans of patients aged 18–50 years were taken. The images were reformatted from the sagittal sections to para-sagittal sections at premolars, canines, lateral incisors, and central incisors measured to the distance of MIC to the tooth apex, to the inferior border of the mandible, to the buccal cortex, and to the lingual cortex.

RESULTS:

MIC among the patients was found to be present in 96.8% of the total subjects. Prevalence between genders showed that it was present in 97.9% of the male patients and 95.5% of the female patients. The average distance from the buccal cortex is 4.88, the lingual cortex is 5.54, inferior border is 9.94, and root apices is 7.67. The age-wise and gender-wise comparison of a mean distance of MIC to the different surfaces in the different cross-sections showed that there is no correlation, and there is a significant correlation, respectively.

CONCLUSION:

The detection of the MIC presence and location using CBCT should be earnestly considered for surgical procedures that are intended to be done in the interforaminal region.

Published: October 2021

OBJECTIVES:

This study aimed to evaluate the extent to which online communication can enhance patients' knowledge of orthodontic topics, as well as compare the effectiveness of images, video, and text messages as tools for delivering orthodontic information.

MATERIALS AND METHODS:

Two WhatsApp groups were created comprising 30 males and 33 females. The Google form template was used to formulate a 25-item questionnaire containing information related to orthodontic topics. At the beginning of the first stage, a link to the questionnaire was sent to the groups and their answers were given scores, which were referred to as (T1). During the second stage, a piece of daily information relevant to the field of orthodontics was sent to the groups over a 14-day period. On Day 15, the link to the previous questionnaire was sent again and the participants were asked to complete it for a second time. These answers were corrected, given scores, and labeled as (T2). Scores from the first and second stages were compared.

RESULTS:

There was a significant increase in the average total score from the first questionnaire (T1 = 15.3) to the second questionnaire (T2 = 17.9). All types of media formats were greatly effective in improving the patients' knowledge. Images proved to be the best tool for delivering information and were considerably more effective than video and text messages.

CONCLUSION:

This study indicates that WhatsApp as an online communication tool could be used to effectively enhance the knowledge of orthodontic patients. Images are the best method for delivering information to orthodontic patients.

OBJECTIVES:

This study aimed to evaluate the visual facial perception in response to scars associated with repaired cleft lip (CL) on a male adolescent model, as assessed by eye-tracking technology.

MATERIAL AND METHODS:

Unilateral and bilateral facial images of repaired CL on the upper lip and nasal asymmetry were added to an image of a male adolescent model, using Photoshop CS5 software. 40 laypeople eye movements were tracked by an infrared sensor of the Eye Tribe hardware in conjunction with OGAMA software. An analysis of variance was used to identify differences in total fixation time for the added areas of interest. A visual analog scale of attractiveness with a questionnaire were also incorporated into the study. Statistical analysis was performed using a significance level of P < 0.05.

RESULTS:

Significant differences were noted between the image with no scar and the image featuring a unilateral scar for total fixation time associated with the right eye (p = 0.002) and right nose area (p = 0.003), in addition to the numbers of fixations for the right eye (p = 0.005) and right nose area (p = 0.007). Comparing the image with no scar with the image featuring a bilateral scar showed a significant difference only for the number of fixations on the right eye (p = 0.005). The heatmaps and fixation point maps for both the unilateral and bilateral scar images indicated increased fixation for the scar areas. For the image with no scar, increased fixation was captured for the right eye area. Pearson's correlation coefficient test showed a moderate positive (p = 0.692) relationship when comparing to unilateral and bilateral cleft scars.

CONCLUSIONS:

The participating laypeople perceived the cleft-repaired faces and did not perceive any difference in attractiveness between the images featuring the unilateral and bilateral postsurgical clefts and lip scarring.
A Study of Dentofacial Morphology in Yemeni Adults with Normal Occlusions a cross sectional prospective study
Authors: Al-Yousefi Amal A. , Al-Motareb Fuad , Daer Ammar , Al-Labani Mohammed A.
Published: October 2021

OBJECTIVE:

The purpose of this study was to describe the dentofacial morphology of Yemeni adults.

MATERIALS AND METHODS:

The lateral cephalograms of 100 Yemeni adults (50 males, 50 females) were included in the study. All subjects were born to Yemeni parents and grandparents. They all had Class I occlusions with minor or no crowding, well-aligned upper and lower dental arches, good facial harmony, all teeth present except third molars, and no history of orthodontic therapy or maxillofacial surgery. Five angular and eighteen linear measurements were analyzed to determine the soft tissue, skeletal, and dental features. The differences for each measurement between Yemeni males and females were calculated using unpaired t–tests.

RESULTS:

Significant sexual and racial differences were found for three linear parameters in the skeletal analysis, one angle, and four linear dental measurements, and for all soft tissue linear parameters. Yemeni adults showed a tendency to a facial pattern of Class II, convex profile, reduced prominence of chin, increased lower facial height, and a clockwise rotation of the mandibular plane angle.

CONCLUSION:

Yemeni adults have different dentofacial parameters when compared to other racial standards, and these differences could aid in diagnosis and treatment planning.

Target Market Selection for the Major Aquaculture Products of Turkey - An Evaluation on Export Markets by Hybrid Multi-criteria Decision-making Approach
Authors: Çelik Pelin , Akmermer Bilgen
Published: October 2021

After 50 years of rapid development, today's aquaculture industry has become one of the driving forces of economic growth in many countries thanks to the increasing aquaculture production. However, less attention has been given to its growing global market demand and its contribution to relevant countries’ trade potential. Turkey has achieved significant success in aquaculture production dominated by Trout (Oncorhynchus mykiss), Sea Bass (Dicentrarchus labrax), and Sea Bream (Dicentrarchus labrax)species thanks to its geographical and biodiversity advantages. Thereby, Turkey has an exporting advantage in the face of increasing global seafood consumption demand. In this paper, we focus on the target market selection of these priority products to support the exporting potential of Turkey. Therefore, this is a multicriterion problem, and this paper aims to provide forecasting about target markets based on qualitative and quantitative criteria by combining fuzzy analytic hierarchy process (FAHP) and the technique for order preference by similarity to ideal solution (TOPSIS) methods. Seven criteria as trade balance, consumption, distance, average tariff, ease of doing business, non-tariff requirement and logistics performance index were chosen for evaluating the target markets. According to FAHP results, the trade balance criterion has the most significant effect while the distance criterion has least effect on the decision problem for ranking the target countries. According to these seven criteria, Japan is the best target market for Trout and Sea Bass while Russian Federation is the best for Sea Bream.

The hectic lifestyle of the human nowadays, makes them prone to have an unbalanced diet, which consists of mostly processed foods, for example: snacks, soft drinks, fried foods, among others. In the following paper, the importance of controlling the type 1 diabetes that occurs mostly in infants and adolescents will be focus, according to the Pan American Health Organization (PAHO), less than 10% correspond to this type, which until this 21st century, there is no cure, but it is possible to have strict control so that these patients could have a better quality of life. It will focus on the control of a balanced diet and medications in which the patient is prescribed by their specialist doctor. This procedure will be done through the development of a mobile app, which is linked to a database in the hospital that the patient may be treating or doing its control, so the doctor can also have a better diagnosis and control if the patient is following with the requirements of its diet and doses of medications that doctor has been prescribing, all this data storage will be done through the mobile application developed on Android, where the patient will have a detailed schedule of their diet, glucose tests to be done and the prescription of the insulin dose

Due to increasing the number of vehicles loans defaulters, the banks subsequently experience more financial risks. Where each day of delay in paying installments they incur massive losses. Although there are several research works have been conducted in this field, the financial banks' concerns have not been addressed thoroughly. Therefore, in this paper we propose the Improved Vehicular Tracking System (IVTS) in order to provide an optimal solution in terms of efficiency, accuracy and reducing banks losses compared with the research works found in the literature. A prototype system based on the proposed design is successfully implemented and tested using Radio Frequency Identification (RFID) and website application.
Water Jet Automation

Published: October 2021

Water jet cutting has been an extremely helpful tool that creates flawless parts with tolerances up to 0.1 mm. During the cutting process, it is important to note that each step must be optimized to create the best finish or maintain the correct tolerance zone. These steps are composed of abrasive mass flow rate, traverse speed, and standoff distance. In order for these optimization techniques to be followed a strict set of rules must be followed to ensure consistent progression. Programs such as MATLAB can be utilized to reduce human error in the calculations. MATLAB files can then be saved to use with other materials and thickness combinations.
