The prevalence of musculoskeletal disorders among dentists in KwaZulu- NatalMoodley, Rajeshree January 2013 (has links)
Magister Chirurgiae Dentium (MChD) / Occupational hazards are common among many professions and dentistry is no exception. Occupational hazards include percutaneous injuries, inhalation of noxious chemicals, noise and musculoskeletal disorders (MSD). Despite the fact that MSD have been documented to
be very prevalent among dentists in various countries, there is a paucity of literature from South Africa. Aim The aim of the present study was to determine the prevalence of musculoskeletal disorders among the dentists in KwaZulu-Natal (KZN), South Africa and to identify risk factors associated with it. The study was a cross-sectional, descriptive one and questionnaires were used to elicit information regarding socio-demographic details, medical history, work history and work-related posture information from dentists based in KwaZulu-Natal. A convenience sample of all qualified dentists in this region who were registered members of the South African Dental Association (SADA) was used. Results One hundred and nine dentists responded to the questionnaire. The response rate was 31%. The majority were male; a third aged between 30 - 39 years and the ratio of females to males was 1:3. Almost all the dentists reported pain in the neck, lower back and shoulder. Less than a quarter of the dentists in KZN reported hand pain, numbness in the hands and a tingling sensation in the hands. More than three quarters reported that they had no negative effects when performing restorative work and scaling and polishing, but 3.1% reported having extreme levels of pain. The most common working position reported was the 2 0' clock position. Nearly three quarters rotated their necks while performing clinical dentistry and a third tilted their shoulders towards their dominant hand. There was no relationship between Body Mass Index (BMI) and whether respondents treated patients while seated or standing and neither was there a relationship between pain in the lower back and BMI. There was a strong association between pain in the neck while performing clinical work and the number of years in practice confounded by age. When compared to other countries the prevalence of MSD is very high. The highest occurrence was for neck, back and shoulder pain. Avoiding these injuries is critical and self-recognition is important in either preventing
further injuries or in increasing severity of the condition. The findings of this study suggests that it may be valuable to include ergonomic work practice in the training of dentists and dentists should be involved in a proper exercise routine which should include stretching and
weight training to prevent injuries. Regular breaks should be taken to perform stretching exercises in-between the management of patients in order to reduce the risk of MSD.

Multi-Modal Sensing Approach for Objective Assessment of Musculoskeletal Fatigue in Complex WorkHamed Asadi (10875660) 13 August 2021 (has links)
<p>Surface electromyography (sEMG) has been
used to monitor muscle activity and predict fatigue in the workplaces. However,
objectively measuring fatigue is challenging in complex work with unpredictable
work cycles, where sEMG may be influenced by the dynamically changing posture
demands. The sEMG is affected by various variables and substantial change in
mean power frequencies (MPF), and a decline over 8-9% is primarily considered musculoskeletal
fatigue. These MPF thresholds have been frequently used, and there were limited
efforts to test their appropriateness in determining musculoskeletal fatigue in
live workplaces (which predominantly consist of complex tasks). In addition,
the techniques that consider both muscular and postural measurements that incorporate
dynamic posture changes observed in complex work have not yet been explored.
The overall objective of this work is to leverage both postural and muscular
cues to identify musculoskeletal fatigue in complex tasks/jobs (i.e., tasks
involving different levels of exertions, durations, and postures). The work was
completed in two studies.</p>
The first study aimed to
(1) predict subjective fatigue using objective measurements in non-repetitive
tasks, (2) determine whether the musculoskeletal fatigue thresholds in
non-repetitive tasks differed from the previously reported threshold, and (3)
utilize the empirically calculated thresholds to test their appropriateness in
determining musculoskeletal fatigue in live surgical workplaces. The findings
showed that the multi-modal measurements indicate better sensitivity than
single-modality (sEMG) measurements in detecting decreases in MPF, a predictor
of fatigue. In addition, the results showed that the thresholds in dynamic
non-repetitive tasks, like surgery, are different than the previously reported
8% threshold. Additionally, implementing muscle-specific thresholds increased
the likelihood of more accurately reporting subjective fatigue. The second
study aimed to develop a multi-modal fatigue index to detect musculoskeletal
fatigue. A controlled laboratory study was performed to simulate the
non-repetitive physical demands at different postures. A series of experiments
were conducted to test the effectiveness of
various metrics/models to identify subjective fatigue in complex tasks. Next, the
composite fatigue index (CFI) function was developed using the time-synced
integration of both muscular signals (measured with sEMG sensors) and postural
signals (measured with Inertial Measurement Unit (IMU) sensors). The variables
from sEMG (amplitude, frequency, and the number of muscles showing signs of
fatigue) and IMU (the prevalence of static and demanding postures and the number
of shoulders in static/demanding posture) sensors were integrated to generate
the CFI function. The prevalence of static/demanding postures was developed
using the cumulative exposures to static/demanding postures based on the material
fatigue failure theory. The single value fatigue index was obtained using the
resultant CFI function, which incorporates both muscular and postural
variables, to quantify the muscular fatigue in dynamic non-repetitive tasks.
The findings suggested that the propagation of musculoskeletal fatigue can be
detected using the multi-modal composite fatigue index in complex tasks. The
resultant CFI function was then applied to surgery tasks to differentiate the
fatigued and non-fatigued groups. The findings showed that the multi-modal
fatigue assessment techniques could be utilized to incorporate the muscular and
postural measurements to identify fatigue in complex tasks beyond
single-modality assessment approaches.

Postures littéraires et modernité dans les chroniques sur les régions d'Arthur BuiesLavoie-Coutu, Isabelle 08 1900 (has links)
Dans notre étude, nous cherchons à démontrer qu'Arthur Buies se présente comme le témoin d'une forme de modernité dans ses chroniques sur les régions qui sont publiées dans les années 1870 dans divers journaux puis rassemblées en trois recueils. En effet, nous nous appuyons sur l'idée qu'il observerait sensiblement les mêmes traits dans ses chroniques rurales que dans ses chroniques urbaines. Nous pensons aussi que les postures littéraires (Jérôme Meizoz) qu'il adopte permettent à Buies de transmettre - de manière formelle - sa vision de la modernité. Au terme de la recherche, il ressort que Buies, conscient de ce qu'est la modernité, juge qu'elle ne se trouve pas inéluctablement dans les villes. Pour lui, Paris et San Francisco sont modernes, alors que Québec ne l'est pas. De plus, pour lui, il existe bel et bien une forme de modernité dans les chroniques rurales, puisqu'il y observe sensiblement les mêmes traits que ceux qu'il relevait dans ses chroniques sur Paris et San Francisco. Aussi, Buies est-il convaincu que la colonisation au Québec stagne. Il en vient à ce constat lorsqu'il la compare à celle se produisant simultanément aux États-Unis. Toutefois, il remarque un certain progrès au cours de la décennie, insuffisant, selon lui, pour compenser l'absence de chemin de fer sur la rive nord du Saint-Laurent. Nous concluons, à partir de nos analyses, que les postures littéraires que Buies choisit - particulièrement celle du flâneur et celle du géographe - lui permettent de véhiculer les traits de la modernité dans l'écriture même de ses chroniques. / In our study, we focus on demonstrating that Arthur Buies presents himself as a witness of a form of modernity in his chronicles on the country published in the 1870's in three collections. We lean on the idea that he would observe approximately the same characteristics in his rural chronicles as in his urban chronicles. We also think that the 'literary postures' (Jérôme Meizoz) adopted by Buies allow him to pass on - in a formal way - his vision of modernity. By the research's end, it stands out that Buies, aware of the concept of modernity, judges that it doesn't inevitably appear in the cities. For Buies, Paris and San Francisco are modern whereas Quebec City is not. Furthermore, for him, there really is a form of modernity in his rural chronicles because he notices in them more or less the same characteristics as the ones he found in the chronicles about Paris and San Francisco. Also, Buies is convinced that the colonization in Quebec stagnates. He comes to this observation when he compares it to the American colonization happening simultaneously. However, he notices some progress regarding Quebec colonization over the decade, but insufficient, according to him, to make up for the absence of a railroad on the northern bank of the St. Lawrence River. Based on our analysis, we conclude that the 'literary postures' chosen by Buies - especially the 'flâneur' and the geographer ones - are figures through which the characteristics of modernity are conveyed within the writing of the chronicles itself.

Designing expressive interaction techniques for novices inspired by expert activities : the case of musical practice / La conception de techniques d’interaction expressives adaptées aux novices et inspirées par des activités expertes : le cas de la pratique musicaleGhomi, Emilien 17 December 2012 (has links)
Les systèmes interactifs étant utilisés pour réaliser des tâches toujours plus complexes et variées, les utilisateurs ont besoin de systèmes qui soient à la fois expressifs, efficaces et utilisables. Si des systèmes simples peuvent être instantanément utilisables, l’expressivité accessible avec des systèmes complexes est souvent considérée comme réservée aux experts. Cependant, notre approche, inspirée par la recherche en phénoménologie et en psychologie, souligne que certaines activités expertes ayant une portée sociale, comme les activités artistiques, permettent aussi aux non-experts d’acquérir des compétences et une connaissance considérables de façon implicite. Dans ce manuscrit, nous évoquerons notamment la connaissance et les compétences avancées développées par les non-musiciens lors de l’écoute de la musique et de l’observation du jeu instrumental. Nous défendons deux idées. Premièrement, les concepteurs de systèmes interactifs peuvent profiter de ces compétences et de cette connaissance implicites pour créer des systèmes expressifs qui soient utilisables. Deuxièmement, les méthodes d'apprentissage expertes et les outils experts, qui ont été perfectionnés à travers le temps et ont fait leurs preuves dans des situations complexes, peuvent servir de sources d'inspiration pour améliorer l’utilisabilité des systèmes complexes pour les utilisateurs novices. Nous proposons un cadre de conception pour étudier l'utilisabilité et l'expressivité des techniques d'interaction, comme deux nouvelles mesures de la qualité de l'interaction, et présentons les trois projets de cette thèse. Dans le premier, nous étudions l'utilisation de motifs rythmiques pour l'interaction, et nous montrons que des utilisateurs novices sont capables de reproduire et de mémoriser efficacement de grands vocabulaires de motifs rythmiques. Une telle interaction tire parti des capacités naturelles des non-musiciens pour percevoir et reproduire des structures rythmiques. Nous définissons des règles pour créer des motifs rythmiques adaptés à l’interaction, et montrons qu’ils peuvent être utilisés efficacement pour déclencher des commandes. Dans le deuxième projet, nous étudions la conception et l’apprentissage de postures multi-doigt sur des écrans multi-tactiles. Nous prenons en compte les contraintes mécaniques et les degrés de liberté de la main pour créer des vocabulaires expressifs de postures multi-doigt, dont nous évaluons l’utilisabilité lors d’une expérimentation. Nous présentons une méthode d’apprentissage adaptée aux postures les plus complexes, inspirée par l’apprentissage des accords en musique, et nous montrons qu’elle peut améliorer la compréhension et la mémorisation. Dans le dernier projet, nous nous intéressons aux applications de création musicale en temps réel, et tentons de les faire profiter des qualités instrumentales des instruments acoustiques. Nous voulons créer des applications qui permettent un jeu virtuose et expressif, et dont les fonctionnalités élémentaires sont accessibles aux novices (comme on peut jouer quelques accords au piano sans apprentissage). Nous proposons un cadre de conception et une architecture logicielle qui aident à considérer la conception d’applications musicales comme une lutherie à part entière. Avec ces projets, nous montrons que, dans ces cas : (i) la connaissance et les compétences implicites des non-experts peuvent être réutilisées en interaction ; (ii) les méthodes d’apprentissage expertes peuvent permettre de rendre les systèmes expressifs plus utilisables ; (iii) s’inspirer des outils experts peut aider à concevoir des systèmes interactifs expressifs et utilisables. Nous proposons l’étude de l’utilisabilité comme une alternative à l’immédiateté prônée par les entreprises d’informatique, et nous présentons des méthodes pour tirer parti de la richesse des activités expertes et de la connaissance implicite des non-experts pour créer des systèmes interactifs expressifs et utilisables par les novices. / As interactive systems are now used to perform a variety of complex tasks, users need systems that are at the same time expressive, efficient and usable. Although simple interactive systems can be easily usable, interaction designers often consider that only expert practitioners can benefit from the expressiveness of more complex systems. Our approach, inspired by studies in phenomenology and psychology, underscores that non-experts have sizeable knowledge and advanced skills related to various expert activities having a social dimension –such as artistic activities–, which they gain implicitly through their engagement as perceivers. For example, we identify various music-related skills mastered by non-musicians, which they gain when listening to music or attending performances. We have two main arguments. First, interaction designers can reuse such implicit knowledge and skills to design interaction techniques that are both expressive and usable by novice users. Second, as expert artifacts and expert learning methods have evolved over time and have shown efficient to overcome the complexity of expert activities, they can be used as a source of inspiration to make expressive systems more easily usable by novice users. We provide a design framework for studying the usability and expressiveness of interaction techniques as two new aspects of the user experience, and explore this framework with three projects. In the first project we study the use of rhythmic patterns as an input method, and show that novice users are able to reproduce and memorize large vocabularies of patterns. This is made possible by the natural abilities of non-musicians to perceive, reproduce and make sense of rhythmic structures. We define a method to create expressive vocabularies of patterns, and show that novice users are able to efficiently use them as command triggers. In the second project, we study the design and learning of chording gestures on multitouch screens. We introduce design guidelines to create expressive chord vocabularies taking the mechanical constraints and the degrees of freedom of the human hand into account. We evaluate the usability of such gestures in an experiment and we present an adapted learning method inspired by the teaching of chords in music. We show that novice users are able to reproduce and memorize our vocabularies of chording gestures, while our learning method can improve long-term memorization. The final project focuses on music software used for live performances and proposes a framework for designing “instrumental” software allowing expert musical playing and having its elementary functionalities accessible to novices, as it is the case with acoustic instruments (for example, one can easily play a few chords on a piano without practice). We define a design framework inspired by a functional decomposition of acoustic instruments and present an adapted software architecture, both aiming to ease the design of such software and to make it match with instrument-making. These projects show that, in these cases: (i) the implicit knowledge novices have about some expert activities can be reused for interaction; (ii) expert learning methods can inspire ways to make expressive systems more usable novices; (iii) taking expert artifacts as a source of inspiration can help creating usable and expressive interactive systems. In this dissertation, we propose the study of usability as an alternative to the focus on immediacy that characterizes current commercial interactive systems. We also propose methods to benefit from the richness of expert activities and from the implicit knowledge of non-experts to design interactive systems that are at the same time expressive and usable by novice users.

Gramática tanimuka, una lengua de la Amazonía colombiana / Grammaire de la langue tanimuka, Amazonie colombienne / Grammar of the Tanimuka language, Colombian AmazonEraso, Natalia 27 May 2015 (has links)
Cette grammaire du tanimuka, langue tucano d’Amazonie colombienne, s’organise en quatre parties. La première partie, ‘le tanimuka : la langue et ses locuteurs’, est divisée en trois chapitres (1 à 3), qui établissent le profil sociolinguistique de la langue, et décrivent les conditions d’enquête de terrain. La deuxième partie, divisée en deux chapitres (5 et 6), présente une description de la phonologie et morphophonologie de la langue, avec une description du phénomène d’épenthèse syllabique dans le verbe. La troisième partie (chapitres 7 et 8) présente d’abord une étude générale de la grammaire au niveau morphosyntaxique et syntaxique, puis une étude thématique approfondie des systèmes de classification nominale : genre et classificateurs numéraux. La quatrième partie, divisée en trois chapitres (9 à 11), se concentre sur le domaine de l’expression spatiale, omniprésente dans la langue. Le premier chapitre présente l’inventaire de tous les éléments de l’expression spatiale de la langue. Le deuxième décrit le fonctionnement des verbes de postures et des positionnels dans les constructions locatives de base de prédicats de base simple ou complexe (séries verbales). Le troisième est dédié à l’étude de l’expression de la trajectoire. La thèse se termine par trois annexes : une présentation des stimuli visuels créés pour les enquêtes sur les verbes locatifs de posture et les positionnels, une étude sur le système de numération traditionnel du tanimuka, et la transcription d’une histoire de tradition orale ‘La tortue de terre Parekika’, glosée et traduite. / This grammar of Tanimuka, a Tucanoan language of the Colombian Amazonian area, is organized in four parts. The first part, ‘Tanimuka : the language and its speakers’, is divided into three chapters (1 to 3), which establish the sociolinguistic profile of the language and describe the fieldwork conditions. The second part, divided into two chapters (5 and 6), presents a description of the phonology and morphophonology of the language, with a study of the phenomenon of syllabic epenthesis in the verb. The third part (chapters 7 and 8) begins with a general study of the morphosyntactic and syntactic levels, followed by an in-depth study of the noun classification systems: gender and numeral classifier. The fourth part (chapters 9 to 11) focuses on the expression of space, omnipresent in the language. The first chapter presents an inventory of all the elements that express the domain of space in the language. The second provides a detailed analysis of postures and positional verbs in basic locative construction of simple or complex predicates (serial verb constructions). The final chapter is dedicated to the study of the expression of the Trajectory category. The dissertation ends with three annexes, which present, in turn, the visual stimuli created for the investigation of locative verbs of posture and position, a study of the traditional system of numeration and the transcription of a history of oral tradition: 'The tortoise Parekika', glossed and translated.

La sexualité analyseur : théories et politiques des sexualités / Non communiquéGras, Olivier 16 January 2012 (has links)
La sexualité est arrivée au statut d’objet scientifique à la suite des découvertes psychanalytiques. L’élargissement du sexuel avec Freud par la théorie de la libido a permis une investigation beaucoup plus large et complète de la sexualité, la faisant apparaître comme un phénomène de totalité. Les sciences sociales n’ont pourtant pas nécessairement intégré cet élargissement dans leurs théorisations sur la sexualité livrant une définition de celle-ci selon leurs paradigmes et cadres interprétatifs disciplinaires. De même, la politisation de la sexualité a dans un premier temps interpréter la question de la libido freudienne dans une utopie critique, celle de la libération sexuelle de Mai 68. Dans un second temps, elle a idéologisé et partialisé la question sexuelle en orientant les débats sur les questions des minorités sexuelles. La démarche critique adoptée dans cette thèse permet de montrer en quoi la sexualité en tant qu’objet est l’analyseur des sexualités concrètes. La sexualité est une force originaire au fondement de la subjectivité, de l’intersubjectivité et des formations sociales. Elle ne peut donc être conceptualisée de façon réductrice. Cette complexité est nécessairement polémique car elle comprend des enjeux épistémologiques, politiques, mais aussi éthiques, praxéologiques et métaphysiques. / Sexuality become a scientific object following psychoanalysic discoveries. The extension of sexuality by Freud with the libido theory allow more complete and broader investigation of sexuality, showing it as a phenomenon of totality. Social sciences however did not insert this enlargement into their theorizings on the sexuality delivering a definition of this one according to their paradigms and disciplinary interpretative frames. Also, the politicization of sexuality has at first interpreted the question of freudian libido in a critical utopia, that of the sexual liberation of Mai 68. In second time, it has ideologised ans partialised the sexual question by orientating the debate on the sexual minorites questions. Critical step adopted in this thesis allows to show that sexuality as object is the analyser of concrete sexualities. Sexuality is a native force in the foundation of subjectivity, intersubjectivity and social trainings. Sexuality can’t be conceptualised in a reductionnist way. This complicacy is necessarily polemical because it consists in epistemological and political stakes, but also in ethical, praxeological and metaphysical stakes.
