¿Es eficaz especializar la actividad de tutoria? Análisis de una experiencia online

En un entorno online la actividad de tutoría de los estudiantes juega un papel fundamental. Su eje central es el acompañamiento del estudiante a lo largo del programa académico que curse, desde el momento en que muestra su interés en matricularse hasta que se titula. La literatura disponible sobre cómo organizar la actividad tutorial en entornos virtuales es escasa. En esta comunicación, basada en la experiencia de la Universitat Oberta de Catalunya (UOC), se analizan dos niveles de especialización de la acción tutorial online. En un primer nivel organizativo, se presenta y evalúa una especialización de la coordinación de la tutoría en función del tipo de conocimiento necesario para ejercerla, académico o administrativo. Esto genera una estructura organizativa de tipo matricial que aporta flexibilidad y conocimiento especializado a la actividad tutorial, y que es valorada muy positivamente por las partes implicadas. En un segundo nivel, se analiza la separación de dos tipos de tutoría especializadas, una de inicio y otra de seguimiento, en función de la antigüedad del estudiante tutorizado. Los resultados de los análisis cualitativos y cuantitativos realizados no permiten concluir que esta segunda forma de especialización contribuya claramente a la mejora de los objetivos de la función tutorial.

SiMR: A simulator for learning computer architecture

This paper presents SiMR, a simulator of the Rudimentary Machine designed to be used in a first course of computer architecture of Software Engineering and Computer Engineering programmes. The Rudimentary Machine contains all the basic elements in a RISC computer, and SiMR allows editing, assembling and executing programmes for this processor. SiMR is used at the Universitat Oberta de Catalunya as one of the most important resources in the Virtual Computing Architecture and Organisation Laboratory, since students work at home with the simulator and reports containing their work are automatically generated to be evaluated by lecturers. The results obtained from a survey show that most of the students consider SiMR as a highly necessary or even an indispensable resource to learn the basic concepts about computer architecture.

Computer-assisted two-dimensional preoperative planning for total hip arthroplasty: clinical evaluation.

The purpose of this study is to clinically validate a new two-dimensional preoperative planning software for cementless total hip arthroplasty (THA). Manual and two-dimensional computer-assisted planning were compared by an independent observer for each of the 30 patients with osteoarthritis who underwent THA. This study showed that there were no statistical differences between the results of both preoperative plans in terms of stem size and neck length (<1 size) and hip rotation center position (<5 mm). Two-dimensional computer-assisted preoperative planning provided successful results comparable to those using the manual procedure, thereby allowing the surgeon to simulate various stem designs easily.

Exploring the implementation of a medication adherence programme by community pharmacists: a qualitative study

BACKGROUND: Medication adherence has been identified as an important factor for clinical success. Twenty-four Swiss community pharmacists participated in the implementation of an adherence support programme for patients with hypertension, diabetes mellitus and/or dyslipidemia. The programme combined tailored consultations with patients about medication taking (expected at an average of one intervention per month) and the delivery of each drug in an electronic monitoring system (MEMS6?). OBJECTIVE: To explore pharmacists' perceptions and experiences with implementation of the medication adherence programme and to clarify why only seven patients were enrolled in total. SETTING: Community pharmacies in French-speaking Switzerland. METHOD: Individual in-depth interviews were audio-recorded, with 20 of the pharmacists who participated in the adherence programme. These were transcribed verbatim, coded and thematically analysed. Process quality was ensured by using an audit trail detailing the development of codes and themes; furthermore, each step in the coding and analysis was verified by a second, experienced qualitative researcher. MAIN OUTCOME MEASURE: Community pharmacists' experiences and perceptions of the determining factors influencing the implementation of the adherence programme. RESULTS: Four major barriers were identified: (1) poor communication with patients resulting in insufficient promotion of the programme; (2) insufficient collaboration with physicians; (3) difficulty in integrating the programme into pharmacy organisation; and (4) insufficient pharmacist motivation. This was related to the remuneration perceived as insufficient and to the absence of clear strategic thinking about the pharmacist position in the health care system. One major facilitator of the programme's implementation was pre-existing collaboration with physicians. CONCLUSION: A wide range of barriers was identified. The implementation of medication adherence programmes in Swiss community pharmacies would benefit from an extended training aimed at developing communication and change management skills. Individualised onsite support addressing relevant barriers would also be necessary throughout the implementation process.

Computer-aided volume measurement of posttraumatic orbits reconstructed with AO titanium mesh plates: accuracy and reliability

PURPOSE: To prospectively evaluate the accuracy and reliability of "freehand" posttraumatic orbital wall reconstruction with AO (Arbeitsgemeinschaft Osteosynthese) titanium mesh plates by using computer-aided volumetric measurement of the bony orbits. METHODS: Bony orbital volume was measured in 12 patients from coronal CT scan slices using OsiriX Medical Image software. After defining the volumetric limits of the orbit, the segmentation of the bony orbital region of interest of each single slice was performed. At the end of the segmentation process, all regions of interest were grouped and the volume was computed. The same procedure was performed on both orbits, and thereafter the volume of the contralateral uninjured orbit was used as a control for comparison. RESULTS: In all patients, the volume data of the reconstructed orbit fitted that of the contralateral uninjured orbit with accuracy to within 1.85 cm3 (7%). CONCLUSIONS: This preliminary study has demonstrated that posttraumatic orbital wall reconstruction using "freehand" bending and placement of AO titanium mesh plates results in a high success rate in re-establishing preoperative bony volume, which closely approximates that of the contralateral uninjured orbit.

Computer-aided system for morphometric mandibular index computation (Using dental panoramic radiographs)

Objective: We propose and validate a computer aided system to measure three different mandibular indexes: cortical width, panoramic mandibular index and, mandibular alveolar bone resorption index. Study Design: Repeatability and reproducibility of the measurements are analyzed and compared to the manual estimation of the same indexes. Results: The proposed computerized system exhibits superior repeatability and reproducibility rates compared to standard manual methods. Moreover, the time required to perform the measurements using the proposed method is negligible compared to perform the measurements manually. Conclusions: We have proposed a very user friendly computerized method to measure three different morphometric mandibular indexes. From the results we can conclude that the system provides a practical manner to perform these measurements. It does not require an expert examiner and does not take more than 16 seconds per analysis. Thus, it may be suitable to diagnose osteoporosis using dental panoramic radiographs.

Design of an Embedded Computer Board for Networking Applications

Tämä diplomityö tehtiin Convergens Oy:lle. Convergens on elektroniikan suunnittelutoimisto, joka on erikoistunut sulautettuihin järjestelmiin sekä tietoliikennetekniikkaan. Diplomityön tavoitteena oli suunnitella tietokonekortti tietoliikennesovelluksia varten asiakkaalle, jolta vaatimusmäärittelyt tulivat. Työ on rajattu koskemaan laitteen prototyypin suunnittelua. Työssä suunnitellaan pääasiassa WLAN-tukiaseman tietokone. Tukiasema onasennettavissa toimistoihin, varastoihin, kauppoihin sekä myös liikkuvaan ajoneuvoon. Suunnittelussa on otettu nämä asiat huomioon, ja laitteen akun pystyy lataamaan muun muassa auton akulla. Langattomat tekniikat ovat voimakkaasti yleistymässä, ja tämän työn tukiasema tarjoaakin varteenotettavan vaihtoehdon lukuisilla ominaisuuksillaan. Mukana on mm. GPS, Bluetooth sekä Ethernet-valmius. Langattomien tekniikoiden lisäksi myös sulautetut järjestelmät ovat voimakkaasti yleistymässä, ja nykyään mikroprosessoreita löytääkin lähesmistä vain. Tässä projektissa käytetty prosessori on nopeutensa puolesta kilpailukykyinen, ja siitä löytyy useita eri rajapintoja. Jatkossa tietokonekortille on myös tulossa WiMAX-tuki, joka lisää tukiaseman tulevaisuuden arvoa asiakkaalle. Projektiin valittu Freescalen MPC8321E-prosessori on PowerPC-arkkitehtuuriin perustuva ja juuri markkinoille ilmestynyt. Tämä toi mukanaan lisähaasteen, sillä kyseisestä prosessorista ei ollut vielä kaikkea tietoa saatavilla. Mekaniikka toi omat haasteensa mukanaan, sillä se rajoitti piirilevyn koonniin, että ylimääräistä piirilevytilaa ei juurikaan jäänyt. Tämän takia esimerkiksi DDR-muistit olivat haastavia reitittää, sillä muistivetojen on oltava melko samanpituisia keskenään. Käyttöjärjestelmänä projektissa käytetään Linuxia. Suunnittelu alkoi keväällä 2007 ja toimiva prototyyppi oli valmis alkusyksystä. Prototyypin testaus osoitti, että tietokonekortti kykenee täyttämään kaikki asiakkaan vaatimukset. Prototyypin testauksessa löytyneet viat ja optimoinnit on tarkoitus korjata tuotantomalliin, joten se antaa hyvän pohjan jatkosuunnittelua varten.

Développement d'un programme de formation à l'entretien motivationnel

RESUMELe but de ce travail de thèse est de permettre à un public de professionnels de découvrir à travers des enregistrements et un texte d'accompagnement l'entretien motivationnel, approche qui est utilisée depuis une vingtaine d'années et qui a fait ses preuves dans le domaine des habitudes de vie influençant la santé.L'entretien motivationnel est d'une part un esprit. Au moyen d'une attitude non jugeante et non confrontante, il crée un climat de confiance favorable à une démarche de changement. Le thérapeute installe une relation de partenariat dans laquelle la personne est autonome dans ses décisions. Cette attitude ou esprit de l'entretien motivationnel repose sur quatre principes de bases qui favorisent le changement.L'entretien motivationnel utilise d'autre part des techniques qui visent à soulever l'ambivalence d'une personne face à une habitude de vie et à la résoudre. Il existe des techniques essentielles pour construire la motivation au changement et des techniques pour construire un plan permettant à la personne de s'engager dans le changement. Ces techniques sont illustrées dans les enregistrements et par le texte d'accompagnementCe travail de thèse contient tous les éléments nécessaires pour prendre connaissance de l'esprit et des techniques de l'entretien motivationnel. Il est néanmoins indispensable de participer à des séminaires de formation pratique et de bénéficier de supervisions pour apprendre à utiliser l'entretien motivationnel.
