O tema central desta dissertação é a percepção de conforto como instrumento para traçar diretrizes para o design de calcinhas, que é o principal objetivo deste estudo. O presente trabalho apresenta uma investigação teórico-metodológica acerca do conforto, do produto estudado, a calcinha e da usuária, a mulher. Esta dissertação teve como objetivo traçar diretrizes de projeto de calcinhas com base na percepção de conforto das mulheres de diferentes perfis físicos e psicológicos. Para tanto, foram definidos três objetivos específicos: i) Elaborar uma taxonomia para calcinhas e conceituar os seus elementos; ii) identificar fatores envolvidos na percepção de conforto em calcinhas; iii) avaliar estes fatores envolvidos na percepção de conforto em calcinhas, de acordo com perfis corporais e psicológicos das mulheres. O desenvolvimento do trabalho foi norteado por três pressupostos: i) a percepção de conforto varia de acordo com o perfil psicológico e corporal de cada mulher; ii) diferentes modelos de calcinha se adéquam a diferentes perfis de mulher e produzem percepções diferentes de conforto; e iii) o estudo do conforto envolve as complexas relações entre usuária e o produto, através de estímulos físicos e psicológicos. Com base nos modelos de avaliação da percepção de conforto e risco de Van der Linden (2004), avaliação do conforto no vestuário de Wages (1974) e os métodos de avaliação da percepção de conforto no uso de calcinhas, desenvolvidos em estudo anterior (Giongo, 2010), esta dissertação foi construída e desenvolvida por meio de dois instrumentos: um questionário online, aplicado a 54 estudantes de universidades da Grande Porto Alegre e um questionário físico, aplicado a 347 estudantes da Universidade Federal do Rio Grande do Sul e Universidade Feevale. Com base em estudo e elaboração de uma taxonomia das calcinhas e na análise do primeiro questionário, foi possível estabelecer parâmetros para avaliar o comportamento de uso das participantes e, com base nestas informações, traçar as diretrizes de projeto para o design de calcinhas. / The central theme of this dissertation, as well as its main objective, is to set comfort perception as a tool to establish guidelines for panty design. This paper presents a theoretical and methodological research about comfort, as well as the manufactured goods studied, panties, in addition to their consumer, women. The aim was to establish guidelines based on the comfort perception of women from different physical and psychological profiles. Hence, three specific objectives were defined: i) develop a taxonomy for that type of underwear, conceptualizing elements ii) identify factors involved in comfort perception of panties iii) evaluate factors involved in comfort perception of panties, according to physical and psychological profiles. This work was guided by three assumptions: i) comfort perception varies according to the psychological and physical distinctiveness of every woman ii) different models of underwear suit different profiles of women and produce different perceptions of comfort, and iii) the study of comfort involves the complex relationship between consumer and manufactured goods, through physical and psychological stimuli. This dissertation was rooted in the evaluation of risk and comfort perception model of Van der Linden (2004), in the clothing comfort evaluation of Wages (1974) and on the methods of assessment of comfort perception in wearing such panties, developed in a previous study (Giongo , 2010), and it was built and completed through the application of two instruments: an electronic questionnaire, answered by 54 students from universities in Greater Porto Alegre, and a paper questionnaire answered by 347 students from the Federal University of Rio Grande do Sul and Feevale University. Founded on the study and development of the taxonomy of this kind of underwear, as well as on the analysis of the first questionnaire, it was possible to establish parameters to evaluate consumer behavior of participants and, from that, establish guidelines for panty design.

Afin de réduire les consommations de carburant et les émissions de CO2, des technologies comme la désactivation de cylindres ont été développées. Deux stratégies ont été à l’étude chez le Groupe PSA, il s’agit de désactivations appelées fixe ou tournante en fonction du nombre de cylindres désactivés au cours d’un cycle moteur. Des modifications importantes du bruit et des vibrations transmises dans l’habitacle de la voiture en sont les conséquences ce qui modifie nettement la perception du confort par le conducteur de la voiture. Ce travail de recherche s’intéresse aux modifications de confort perçu par le conducteur dues à ces différentes stratégies appliquées au moteur ainsi qu’aux solutions potentielles qui permettraient d’améliorer ce confort. Parmi ces solutions se trouve le principe de sonification en temps réel du bruit moteur. Pour répondre à ces questions, cinq tests perceptifs sont réalisés. Les deux premiers consistent en l’évaluation du confort global dans différentes configurations ainsi qu’à la validation de l’utilisation d’un simulateur vibro-acoustique. Ces expériences ont montré qu’une des stratégies de désactivation était jugée significativement plus inconfortable que les autres. Par la suite, une seule des stratégies sera retenue. La troisième expérience permet de déterminer un seuil d’acceptabilité entre les sollicitations du moteur avec désactivation et celles du moteur habituel. Ceci afin de fixer une cible pour laquelle l’environnement vibro-acoustique serait acceptable. Dans les deux dernières expériences, deux solutions permettant d’atteindre cette cible sont simulées. La première consiste à modifier la plage de régime moteur ou à lieu la désactivation, la deuxième consiste à assouplir les suspensions horizontales afin de limiter les résonances vibratoires à faible régime. / The technology of cylinder of deactivation has been developed in order to reduce gas consumption and CO2 emissions. Two strategies were studied at groupe PSA called fixed and rotating deactivations depending on the number of cylinders deactivated per engine cycle. This implies non neglecting modifications of sound and vibrations transmitted to the car cabin depredating the global comfort of the car. This research work focused on how driver’s comfort was altered by these engine configurations and how it would be possible to improve this comfort. Among the solutions possible, appears the principle of real-time sonification of the engine noise. To answer these questions, five perceptual experiments have been conducted. First, the aim was to evaluate global comfort with different engine configurations and validate the use of a vibro-acoustic simulator. This showed that one deactivation strategy was significantly reducing the comfort evaluation. Then, we focused on the second strategy which was also considered as not comfortable. On the third experiment, we were interested in finding an acceptable threshold between the vibrations and sounds with the deactivation and with the usual engine configuration. This led to a target of signal to reach in order to provide acceptable situations in terms of sound and vibrations. In the last two experiments, we were interested in the simulation of two solutions about the deactivation settings that would reduce the annoyance: the modification of the engine speed range in which the deactivation occurs and the softening of horizontal suspensions part in order to reduce vibrations resonances at low engine speed.
