Genioplasty with surgical guide using 3D-printing technology : a systematic review

The purpose of this systematic review is to evaluate the current state of the art of making genioplasties using 3D printing technology. A multi-database single-reviewer systematic review identified sixteen papers that fulfilled the selection criteria. There were mainly case series and case reports available (Level IV of the Oxford Evidence-based medicine scale); only two prospective study (Level III) evaluated this subject. These articles are analyzed in details and summarized in this review. The realization of genioplasties with surgical guide using 3D-printing technology could improve predictability and accuracy. It protects anatomical structures in the environment of the surgery, reducing by this way the morbidity and providing safer results. The type of printer and material used as well as the sterilization techniques should be further developed by the authors. The use of open-access software should also be further explored to allow the use of these new technologies by the largest number of surgeons. Finally, prospective multi-center studies with larger samples should be performed to definitively conclude the benefits of this new technology and allow for its routine use. This article is the first systematic review on this topic

Projet AGIL. Chantier pilote de la Réunion : compte-rendu de la mission CIRAD, IRD, IFREMER du lundi 22 mars au vendredi 2 avril 2004

AGIL pour Aide à la Gestion Intégrée des Littoraux est à la fois : a) un projet de recherche action répondant à l'appel d'offre du Réseau Terre-Espace lancé par le Ministère de la Recherche et de la Technologie pour accroître les applications du spatial et mieux faire correspondre l'offre en ce domaine à la demande des utilisateurs ; b) un consortium d'instituts publics et d'entreprises privées regroupant le BRGM, BRL Ingénierie, le CNES, le CIRAD, l'IFREMER, l'IRD et SCOT1 pour mettre en oeuvre ce projet et développer une offre de services aux échelles nationale et internationale sur la gestion intégrée des littoraux. Commencé en avril 2003, le projet AGIL est d'une durée de deux ans. La première année a été consacrée à un état de l'art portant sur la gestion intégrée des zones côtières (GIZC), sur les capteurs spatiaux et sur l'utilisation de la télédétection pour la GIZC. De cet état de l'art, ont été tirés des enseignements qui seront mis en oeuvre dans le cadre de deux chantiers "pilotes", l'un situé en zone tempérée, il s'agit du littoral du Languedoc-Roussillon, l'autre en zone tropicale, il s'agit du littoral de la Côte Ouest de l'île de La Réunion. Travailler sur ces chantiers, doit permettre au consortium AGIL de faire la démonstration de ses capacités d'intégration de ses moyens en compétences et outils. Le choix du site de La Réunion s'est vite imposé en raison des considérations suivantes : a) le territoire est de taille modeste mais est l'objet d'enjeux institutionnels forts, qu'il s'agisse ; (i) du projet de création d'une réserve marine sur son littoral corallien, (ii) de la mise en oeuvre de l'intercommunalité dans un contexte marqué par des communes étendues depuis la ligne de rivage jusqu'au sommet des bassins versants, (iii) de la gouvernance d'un espace soumis à une pression anthropique élevée, génératrice de tensions sociales et de dégradations écologiques potentielles ; b) la gestion intégrée du littoral passe par la prise en compte des dynamiques naturelles et anthropiques des bassins versants ; c) les usages du littoral sont multiples : pêche vivrière, récréative, commerciale informelle, tourismes international et local, habitat balnéaire,... d) Il existe de nombreuses données mobilisables ; ainsi, rapporté à sa taille, le "lagon de La Réunion" est probablement le plus étudié au monde. Objectifs de la mission : - Rétablir le contact avec les acteurs locaux et partenaires à associer au projet ; - Positionner le projet AGIL par rapport aux partenaires institutionnels et aux autres projets en cours portant sur le littoral ou les bassins versants de la zone étudiée ; - Définir la démarche à mettre en oeuvre ; - Elaborer le programme de travail des "fiches cas" et leur calendrier.

Collaborative Tagging as a User-Generated Tool for the Organisation of Online Healthcare Resources: Research Proposals

This paper examines the potential of collaborative tagging to organise online healthcare resources. First, users‘ tags are compared to librarians‘ descriptors. The comparison shows that the majority of tags are relevant and useful for the information retrieval process. Moreover, numerous tags provide the tagged resources with additional access points compared with descriptors. Second, an analysis of end-users‘ seeking practices is envisioned in order to find out if collaborative tagging could help them in their information retrieval process. To collect the relevant data, three successive steps are considered: ethnographical observations, in-depth interviews and focus groups.info:eu-repo/semantics/nonPublishe

Searching for healthcare articles on the Internet: User-generated metadata VS librarians’ descriptors

With the exponential increase of resources available on the Internet, it has become crucial to sort the incredible amount of online content in order to retrieve the information relevant to a particular need. For their information needs, most Web users rely on search engines, such as Google, performing a full text indexation. Opposite to this automated indexation is the one accomplished by professionals using controlled vocabularies allowing to reach a high precision level in terms of search results. Nevertheless, the amount of online resources exceeds the professionals’ capacities to index. For some time now, a new practice called collaborative tagging has been considered as a compelling alternative to professional indexing for online resources. Collaborative tagging describes the process of ordinary users adding metadata in the form of tags to online content (i.e. websites bookmarks, photographs, computer games or music) in order to store and organize it. The assigned tags become immediately available for others to see and use as a means of information retrieval. The emergent list of freely assigned tags is commonly referred to as a ‘folksonomy’ (short for “folk taxonomy”), meaning a user-generated taxonomy. This paper aims at measuring the extent to which the collaborative tagging process contributes to the organization of healthcare resources on the Internet in comparison with descriptors assigned by professionals. To do so, a quantitative and qualitative analysis is conducted on a sample of scholarly articles in the healthcare field listed at the same time in Delicious (a general collaborative tagging system), CiteULike (an academic collaborative tagging system) and PubMed (a bibliographic database referencing journal articles in the life sciences). For each resource of the sample, users’ tags from CiteULike and Delicious, and keywords assigned by PubMed librarians are compared using the methodology proposed by Kipp (2006). This study builds on previous work examining online resources and their associated tags assigned by Delicious users in comparison with descriptors provided by librarians from CISMeF (a French expert gateway of online resources in the healthcare field). This study showed that Delicious users tend to assign tags that are identical to descriptors or more general. It was also found that numerous tags provide additional access points to the tagged resources compared with descriptors. The majority of tags are then relevant and useful for the information retrieval process. Nevertheless a quarter of the assigned descriptors were not represented at all by any of the users’ tags. This study thus demonstrated that users’ tags complement librarians’ descriptors and even compete with them but can in no way be substitute for them. The current study aims at strengthening the findings from this previous work by examining metadata assigned to another type of resources and by three different sort of actors. Next to the comparison of tags with descriptors performed in previous research, the innovation of the current article lies in the analysis of users’ tags from various collaborative tagging systems. This study thus attempts to confirm our assumption that tags from CiteULike users are more specialized than those from Delicious users given that CiteULike is expressly made for academics. The analysis of tags assigned by various types of users allows to measure their differences and similarities in terms of indexing practices.The question raised by this paper concerns not so much the intrinsic value of user-generated metadata but rather how to manage the incredible amount of information we have to deal with on a daily basis. Our previous and current findings demonstrate that instead of mourning the seeming impossibility of replacing conventional taxonomies with user-generated ones, the future of online resources management lies in the integration of new forms of classification schemes with well-studied modes.info:eu-repo/semantics/nonPublishe
