Desenvolupament d'interfícies d'usuari i visualització d'imatge mèdica en dispositius mòbils Android

Aquest treball tracta sobre la realització d’una aplicació per a dispositius Android que permeti visualitzar imatges mèdiques. Amb la col·laboració del parc Taulí de Sabadell s’han realitzat tasques de recerca de requeriments com l’elaboració d’una entrevista o la realització d’una maqueta de paper que s’ha sotmès a una avaluació heurística en un procés iteratiu. Finalment, s’ha implementat una aplicació on es poden visualitzar imatges mèdiques, fer accions sobre elles com canviar el color o fer zoom i accedir a informació del pacient.

Effects of punishment in a mobile population playing the prisoner’s dilemma game

We deal with a system of prisoner’s dilemma players undergoing continuous motion in a two-dimensional plane. In contrast to previous work, we introduce altruistic punishment after the game. We find punishing only a few of the cooperator-defector interactions is enough to lead the system to a cooperative state in environments where otherwise defection would take over the population. This happens even with soft nonsocial punishment (where both cooperators and defectors punish other players, a behavior observed in many human populations). For high enough mobilities or temptations to defect, low rates of social punishment can no longer avoid the breakdown of cooperation

Measuring Customer Experience in Mobile Internet

Problems in the mobile services are complex where the lack of the user analysis is not the modest issue. User centered design has increasingly become as a basis for the design of mobile services. The concept of user centered design gives end-user extensive attention at each stage of the design process. Mobile service providers want to offer experiences for users and clearly the users look for services that can provide pleasant experiences. In this thesis, the elements of user experience in mobile internet were studied as well as user experience measuring methods were researched. This study was looking for user experience measuring metrics and methods to specify new factors to measure user experience. During this thesis research project an application called CEM4Mobile was designed and implemented. CEM4Mobile is an application for observing and analysing user experience based on the user activity and behaviour. As a result of this thesis, a collection of user experience elements and measuring metrics were found. The elements and metrics were designed and implemented to CEM4Mobile product, which measures user experience. It was found out that the user experience measuring methods were based on interaction between two people but CEM4Mobile makes user observation programmatic.

Prevalence of Problematic Mobile Phone Use in British Adolescents

The problematic use of mobile phones among adolescents has not been widely studied. There are very few instruments for assessing potential technological addiction to mobile phones, or for categorizing different types of users or uses. The most widely used scale is the Mobile Phone Problem Use Scale (MPPUS), which is used to study adult populations, and has been applied in various forms in international contexts. The aims of this study were to adapt the Spanish version of this scale (MPPUSA) to British adolescents, and then to estimate the prevalence of possible problematic users. A questionnaire was administered to a sample of 1,529 secondary school pupils aged between 11 and 18 years, with 1,026 completed questionnaires being collected. The analysis showed that the factor and construct validity and reliability were comparable to those obtained in previous studies. The prevalence of problematic users among the students was 10%, and the typical problematic user tended to be an adolescent between 11 and 14 years old, studying in a public school, who considered themselves to be an expert user of this technology, who made extensive use of his/her mobile phone, and who attributed the same problem of use among their peers. These users presented notable scores in all the symptoms covered by the scale used to assess problematic use. In conclusion, the adaptation of the MPPUSA as a screening scale for British adolescents presents good sensitivity and specificity for detecting the main addictive symptoms proposed in this validated version.

Adaptación española del "Mobile Phone Problematic Use Scale" para población adolescente

El uso problemático del teléfono móvil es un fenómeno emergente en nuestra sociedad, que parece afectar especialmente a la población adolescente. El conocimiento acerca del uso problemático de esta tecnología resulta necesario, dado que puede desarrollarse un patrón comportamental con características adictivas. Apenas existen escalas que midan el posible uso problemático del móvil y ninguna adaptada exclusivamente a población adolescente española. La escala más utilizada internacionalmente es la Mobile Phone Problematic Use Scale (MPPUS). El objetivo de este estudio es adaptar el MPPUS a la población adolescente española. Se administró la versión española del cuestionario a una muestra de 1132 de 12 a 18 años. La fiabilidad y la validez factorial eran comparables a las obtenidas en población adulta, por lo que la medida del uso problemático del móvil en los adolescentes españoles es unidimensional. Se detectó una prevalencia del 14.8% de usuarios problemáticos.

Mobile Communication 2012 : Experiències i recerques sobre comunicació mòbil

La comunicació mòbil és un dels temes de més actualitat en diferents fòrums, des de diferents perspectives. Espanya juga un paper important per les dinàmiques i l’evolució del seu mercat. En aquest sentit, el nostre país ofereix un interès específic per l'amplitud del seu parc de dispositius 3G (el segon d'Europa, després d'Itàlia) i per la intensitat del desenvolupament de xarxes socials mòbils, a més de per la creixent implicació d'empreses en la producció i distribució de continguts mòbils. Com va passar amb Internet, es tracta d’un procés d'innovació pel qual els formats de contingut, les pràctiques de consum i els models de negoci característics de la televisió i la xarxa, per exemple, s'adapten, primer, al nou mitjà, per a després desenvolupar formes i models específics que aprofiten les potencialitats de personalització, geolocalització i conectivitat ubiqua.

Ohjelmistotestaus ja ketterät menetelmät

Tämän tutkimuksen tavoitteena on selvittää, miten erityyppisissä organisaatioissa ohjelmistotestaus on organisoitu, sekä mitä ongelmia ja etuja testauksen toimenpieteissä on käytännössä havaittu. Tutkimuksessa kiinnitetään huomiota myös testausresurssien määrään ja asiakkaan toimintaan ohjelmistokehitysprojekteissa. Tässä tutkimuksessa keskityttiin selvittämään ketterien menetelmien vaikutusta ohjelmistotestauksen toteuttamiseen, sekä miten ketterät menetelmät vaikuttavat asiakkaiden toimintaan ohjelmistokehitysprojekteissa. Tutkimus toteutettiin laadullisena tutkimuksena, jossa tutkimusmenetelmänä käytettiin aineistopohjaista menetelmää. Tutkimusaineisto on kerätty haastattelemalla 12 organisaatioyksikön edustajia. Tutkimuksessa havaittiin, että ketterien menetelmien käytöllä voidaan järjestää lisää aikaa ohjelmistotestauksen toteuttamiseen. Ketterissä menetelmissä testaus sidotaan kehitysprosessiin tiiviisti, jolloin testaustoimenpiteet tulee huomioida jo kehitystyön alkaessa. Tällainen lähtökohta tasaa testausresurssien tarvetta, koska testaustoimenpinteitä voidaan suorittaa projektin alusta lähtien. Ketterien menetelmien havaittiin vaikuttavan myös asiakkaan toimintaan. Ketteriä menetelmiä varten toimittajaorganisaation on lisättävä yhteistyön ja kommunikoinnin määrää asiakkaan kanssa. Lisäksi asiakkaalta vaaditaan jatkuvaa läsnäoloa sekä ymmärrystä ketterästä kehityksestä, jotta kehittäjät saavat jatkuvasti palautetta nopean ja joustavan kehityksen takaamiseksi.

'No country for old men?' Analyzing older people s attitudes toward mobile communication

Mobile technology plays an increasing role in interpersonal communication,representing a useful resource for different age cohorts. While the usage ofmobile communication by younger people has received a wide attention fromcommunication scholars, its usage by older people is less explored. Thegoal of our research project is to analyse the usage of mobile phones by theelderly in Italy. We conducted 51 semi-structured interviews in Rome and in amid-range town located in Umbria, between October 2013 and February 2014.Our study explores older users¿ motivations and usage practices, their perceptions of mobile phones, theiradoption and domestication of mobile phones, their usage skills. More specifically,our analysis focuses on: - personal characteristics - personal networks (personalnetwork composition, self-perceived social life, communication channels) -adoption of mobile telephone - consumption patterns of mobile devices - usedmobile services - location and mobility of mobile telephone - current mobilecharacteristics - attitude and opinions towards mobile technology Our preliminaryresults show major differences in users¿ behaviours and perceptions, that canbe related to age cohorts (younger olds vs older olds); socio-cultural levels;vital trajectories (in terms of professional and familiar status); and gender.

Construção de câmara de luz ultravioleta para fotopolimerização de fases estacionárias monolíticas

Eletrocromatografia capilar: contextualização, estado da arte e perspectivas

Capillary electrochromatography (CEC) is a separation technique in which the mobile phase flow is based on the application of a voltage across a packed capillary, which generates an electroosmotic flow that transports the analytes along the capillary toward the detector. As it combines the separation mechanisms of high-performance liquid chromatography (HPLC) and of capillary electrophoresis (CE), CEC can be considered a hybrid of HPLC and CE. This review presents some fundamental aspects of CEC and is focused on the instrumental advances of the technique, such as column technology, operation modes and detection systems, presenting recent papers on these topics and some applications and perspectives about CEC.
