The sensing behavior of SnO2-based thick film gas sensors in a flow system in the presence of a very low concentration (ppb level) of chemical agent simulants such as acetonitrile, dipropylene glycol methyl ether (DPGME), dimethyl methylphosphonate (DMMP), and dichloromethane (DCM) was investigated. Commercial SnO2 [SnO2(C)] and nano-SnO2 prepared by the precipitation method [SnO2(P)] were used to prepare the SnO2 sensor in this study. In the case of DCM and acetonitrile, the SnO2(P) sensor showed higher sensor response as compared with the SnO2(C) sensors. In the case of DMMP and DPGME, however, the SnO2(C) sensor showed higher responses than those of the SnO2(P) sensors. In particular, the response of the SnO2(P) sensor increased as the calcination temperature increased from 400 °C to 800 °C. These results can be explained by the fact that the response of the SnO2-based gas sensor depends on the textural properties of tin oxide and the molecular size of the chemical agent simulant in the detection of the simulant gases (0.1–0.5 ppm).
Adapting Yeast as Model to Study Ricin Toxin A Uptake and Trafficking
Authors: Becker Björn , Schmitt Manfred  J.
Published: July 2011

The plant A/B toxin ricin represents a heterodimeric glycoprotein belonging to the family of ribosome inactivating proteins, RIPs. Its toxicity towards eukaryotic cells results from the depurination of 28S rRNA due to the N-glycosidic activity of ricin toxin A chain, RTA. Since the extention of RTA by a mammalian-specific endoplasmic reticulum (ER) retention signal (KDEL) significantly increases RTA in vivo toxicity against mammalian cells, we here analyzed the phenotypic effect of RTA carrying the yeast-specific ER retention motif HDEL. Interestingly, such a toxin (RTAHDEL) showed a similar cytotoxic effect on yeast as a corresponding RTAKDEL variant on HeLa cells. Furthermore, we established a powerful yeast bioassay for RTA in vivo uptake and trafficking which is based on the measurement of dissolved oxygen in toxin-treated spheroplast cultures of S. cerevisiae. We show that yeast spheroplasts are highly sensitive against external applied RTA and further demonstrate that its toxicity is greatly enhanced by replacing the C-terminal KDEL motif by HDEL. Based on the RTA resistant phenotype seen in yeast knock-out mutants defective in early steps of endocytosis (∆end3) and/or in RTA depurination activity on 28S rRNA (∆rpl12B) we feel that the yeast-based bioassay described in this study is a powerful tool to dissect intracellular A/B toxin transport from the plasma membrane through the endosomal compartment to the ER.

Teoría del salario de eficiencia y disparidades no compensadoras : evaluación a partir de la encuesta Fqp,

por Jean-Michel Plassard, Gabriel Tahar.

El presente artículo tiene el propósito de probar la hipótesis del salario de eficiencia a partir de datos sobre los salarios sacados de la encuesta Formación-Cualificación profesional, Una vez que se han tomado en cuenta todos los factores que pueden justificar diferencias de salarios entre individuos (formación, experiencia profesional, períodos de desocupación anteriores,...), subsisten diferencias de salario inexplicadas : éstas pueden ser atribuídas a políticas diferenciadas en materia de salarios: el "mecanismo" del salario de eficiencia no desempeñaría de manera idéntica el mismo papel en todos los sectores y se manifestaría por lo tanto por diferencias de salarios no ligadas a las características de la oferta de trabajo.
Formation des salaires, chômage d'équilibre et incidence des cotisations sur le coût du travail

Formación de los salarios e incidencia de las cotizaciones sobre el coste del trabajo,

por Jean-Philippe Cotis, Abderrahim Loufir.

Los modelos macroeconómicos franceses atribuyen a las cotizaciones sociales de asalariados y empleadores un impacto asimétrico sobre el coste del trabajo : las alzas de cotizaciones de asalariados acarrearían una baja del salario neto que dejaría constante el coste del trabajo total mientras que las alzas de cotizaciones de empleadores se repercuterían íntegramente en aumento del coste del trabajo. El estudio presentado aquí tiene por objeto probar de manera empírica, para Francia y cinco otros países europeos, la validez de esta propositión, mediante una "ecuación de salario" que incorpora los índices de cotizaciones de asalariados y empleadores. Parece que ni las cotizaciones patronales ni las cotizaciones salariales influyen a mediano plazo en el coste del trabajo; al contrario, tienen influencia sobre el poder adquisitivo de los salarios netos. Una variación de cotizaciones patronales influye en particular en el coste del trabajo sólo de manera transitoria.

Penuria de divisas y crisis de la agriculture comercial en Africa subsahariana,

por Jean-Claude Berthélemy y Christian Morrisson.

En este artículo se presenta un análisis macroeconómico simple que permite explicar la aparición de una penuria de divisas en países africanos de especialización agrícola, mantenida por los propios países. Un racionamiento inicial de divisas, provocado con frecuencia por errores de política económica, créa una penuria de bienes manufacturados en las zonas rurales. A raíz de ello, los campesinos no se yen estimulados a producir para el mercado, lo cual provoca una disminuciôn de los ingresos en divisas y, por ende, una agravación de la crisis de la balanza de pagos. Por último, el présente artfculo propone una aplicación numérica para una muestra formada por unos diez paíees africanos.
Device-associated infections rates in pediatrics and neonatal intensive care units in El Salvador: Findings of the INICC
Authors: Dueñas Lourdes , Bran de Casares Ana , Rosenthal Victor Daniel , Jesús Machuca Lilian
Published: July 2011

Introduction: This study aimed to determine the rate of device-associated, health care-associated infection (DA-HAI), the excess in length of stay, the mortality, and the hand hygiene compliance in a pediatric intensive care unit (PICU) and a neonatal ICU (NICU) in a hospital member of the International Infection Control Consortium (INICC) in El Salvador. Methodology: A prospective cohort, active DA-HAI surveillance study was conducted on patients admitted in the pediatric and neonatal ICUs from January 2007 to November 2009. The protocol and methodology implemented were developed by INICC. Data were collected in the participating ICUs, and analyzed at INICC headquarters by proprietary software. DA-HAI rates were recorded by applying the definitions of the Centers for Disease Control and Prevention National Healthcare Safety Network. Results: Of 1,145 patients hospitalized in the PICU for 9,517 days, 177 acquired DA-HAIs (overall rate 15.5%), and 18.6 DA-HAIs per 1,000 ICU-days. Furthermore, 1,270 patients hospitalized in the NICU for 30,663 days acquired 302 DA-HAIs (overall rate 23.8%), and 9.8 DA-HAIs per 1,000 ICU-days. The central line-associated bloodstream infection (CLA-BSI) rates in the NICU and PICU were 9.9 and 10.0 per 1,000 catheter-days respectively. The ventilator-associated pneumonia (VAP) rate was 16.1 per 1,000 ventilator-days in the NICU and 12.1 in the PICU.The catheter-associated urinary tract infection (CAUTI) rate was 5.8 per 1,000 catheter-days in the PICU. Conclusions: DA-HAI rates in the PICU and NICU of our hospital were higher than international standards; infection control programs including surveillance and antibiotic policies must be a priority in El Salvador.

Published: July 2011

Considering the importance of the mechanisms involved in quinolone resistance, this study evaluate the presence of PMQR in 126 epidemic and not epidemic strains of Salmonella spp. It was noted that presence of PMQR, by itself, did not generate resistance to ciprofloxacin;  but detection of qnr genes in Salmonella spp. and the identification of the qnrB19 variant in a strain of poultry origin alert for the indiscriminate use of quinolones in poultry production, that can result in a pressure for mutant selection of resistant strains with a clinical limitation use of FQs in the near future. And last but not least, is the need to continued study of resistance mechanisms and to monitor the microbial resistance profile of epidemiological strains.

Despite the recognition that tophus regression is an important outcome measure in clinical trials of chronic gout, there is no agreed upon method of tophus measurement. A number of methods have been used in clinical trials of chronic gout, from simple physical measurement techniques to more complex advanced imaging methods. This article summarizes methods of tophus measurement and discusses their properties. Physical measurement using Vernier calipers meets most aspects of the Outcome Measures in Rheumatology (OMERACT) filter. Rigorous testing of the complex methods, particularly with respect to reliability and sensitivity to change, is needed to determine the appropriate use of these methods. Further information is also required regarding which method of physical measurement is best for use in future clinical trials. The need to develop and test a patient-reported outcome measure of tophus burden is also highlighted.
La consultation en pédiatrie : la première approche à la santé mentale des enfants

Published: July 2011

Résumé Ce projet postule l’examen médical pédiatrique comme le premier abordage de la santé mentale des enfants. Nous proposons de promouvoir une perspective plus intégrale de la santé des enfants qui mette à profit la connaissance des pédiatres sur le développement en santé des bébés au cours de leurs premières années de vie, afin que ces professionnels puissent contribuer à la détection précoce et à la prévention des problèmes de santé. A cette fin, nous offrons une formation aux pédiatres sur l’échelle ADBB (Alarme Détresse Bébé), qui a été validée par de nombreuses équipes dans différents pays et qui est d’application facile. Cet outil, qui consiste à observer systématiquement l’enfant, a été mis au point pour détecter précocement des indicateurs de détresse dans le développement affectif des petits (Guedeney, 2001). L’échelle ADBB a été appliquée à 73 enfants âgés de deux à 24 mois. En cas de détection d’un ou plusieurs indicateurs de risque, ce projet vise à fournir aux pédiatres formés à l’utilisation de l’échelle, des ressources leur permettant de renverser cette situation. Ces interventions, notamment l’évaluation ciblée de l’enfant au moyen de l’échelle ADBB, auront lieu dans le cadre d’un suivi pédiatrique régulier de l’état du bébé. Environ cinq mois après la première évaluation effectuée à l’aide de cette échelle et après suivi et prise en charge de l’enfant par le pédiatre, il sera procédé à une deuxième évaluation ADBB, afin de réévaluer l’état de l’enfant. L’application de l’échelle en deux temps permettra de montrer l’évolution des signes détectés et guidera notre évaluation de l’efficacité de l’intervention. L’objectif global de ce projet est de promouvoir un modèle interdisciplinaire de détection et d’intervention précoces, dès les premiers mois de vie, dans le cadre des soins primaires de santé.
Les racines de l'estime de soi : apports de la théorie de l'attachement
Authors: Guédeney Nicole
Published: July 2011

Résumé L’auteur s’intéresse aux différentes dimensions de l’estime de soi et à l’apport de la théorie de l’attachement à la composante interpersonnelle de l’estime de soi. Prendre en compte l’origine développementale de l’estime de soi et sa construction en interaction aux réactions de l’environnement dans les situations de détresse et d’alarme de l’enfant permet de visiter le sentiment de honte de certains adultes, la notion de parentification et la difficulté à supporter l’échec, en particulier dans les professions soignantes.
Les émotions de la cause animale
Authors: Traïni Christophe
Published: July 2011

Résumé Le concept de dispositif de sensibilisation vise à assurer l’ancrage empirique de l’étude des supports matériels, des agencements d’objets, des mises en scène que les militants déploient afin de susciter des réactions affectives qui prédisposent ceux qui les éprouvent à s’engager ou à soutenir la cause défendue. En ce qui concerne la cause animale, l’analyse historique et idéal-typique permet d’expliciter dans quelle mesure ces dispositifs peuvent alimenter des registres émotionnels bien distincts. Le premier relève d’une logique « démopédique » qui exalte les visées pédagogiques des précepteurs de la cause animale, le second d’une logique de « l’attendrissement » qui porte des secouristes à remédier à la souffrance immédiate des bêtes dignes d’affection, le troisième d’une logique du « dévoilement » qui conduit des justiciers à dénoncer les activités effroyables qui se trament à l’abri du regard du public. La valorisation de l’un ou l’autre de ces registres émotionnels ne peut être exclusivement envisagée comme le résultat de calculs stratégiques. L’article examine dans quelle mesure les émotions valorisées par les militants prolongent des sensibilités forgées tout au long de leur propre histoire affective. Ce faisant, il s’agit de déjouer les visions réductrices du militantisme et des mobilisations qui résultent des présupposés utilitaristes et stratégiques du modèle dit du processus politique.

Authors: Pilnière Véronique , Merlo Christophe
Published: July 2011

Résumé À la demande d’une entreprise confrontée au besoin de réfléchir à son identité et à son fonctionnement collectif, nous sommes intervenus dans une phase de diagnostic visant à caractériser les problèmes rencontrés et à apporter des pistes de réflexion pour les résoudre. Ce diagnostic a été réalisé dans le cadre d’un projet portant sur l’amélioration du processus de satisfaction client de l’entreprise. Nous avons proposé une démarche transdisciplinaire intégrant des points de vue issus des approches en sciences de gestion et des points de vue issus du génie industriel, à travers une vision systémique qui a permis de requalifier les besoins exprimés par l’entreprise. La démarche ainsi mise en œuvre s’est appuyée sur des interviews à l’aide de guides d’entretien mixtes, la réalisation d’une analyse enrichie par rapport aux démarches mono-disciplinaires, pour finalement aboutir à des conclusions dont certaines prenaient à contrepied les croyances des responsables de l’entreprise. Ce travail a été riche d’enseignements tant pour l’entreprise que pour les deux intervenants.
La projection : pour le meilleur et pour le pire
Authors: Brusset Bernard
Published: July 2011

Résumé L’auteur relève, dans l’article de Freud sur la projection de 1922, l’oubli des idées antérieures du texte de 1910 sur Schreber, idées à partir desquelles Lacan a introduit la phase du miroir et la notion de forclusion. Le narcissisme spéculaire dans ses rapports avec l’imago maternelle, déjà repérable chez Freud, a été illustré par un cas clinique d’homosexualité publié par l’auteur en 2006. Après avoir situé l’induction de pensée chez Freud, il souligne l’importance du modèle de la projection primordiale dans le tri narcissique entre ce qui est constitutif de soi et étranger à soi. Il montre que la symétrie entre projection et introjection des auteurs kleiniens est mise en suspens par la transitionnalité winnicottienne qui lui est logiquement antérieure. Il considère la notion bionienne d’identification projective comme de seconde génération par rapport à celle de M. Klein.
Gustav Mahler : jalousie et rivalités
Authors: Coblence Françoise
Published: July 2011

Résumé Le musicien viennois Mahler rencontre Freud une unique fois en août 1910, à la suite de ses difficultés conjugales avec Alma et de la liaison de celle-ci avec Gropius. La visite semble couronnée de succès, mais Mahler meurt quelques mois plus tard. Après Freud, la psychanalyse se penchera à de nombreuses reprises sur « le cas Mahler », non seulement pour analyser sa jalousie et son lien à sa mère, mais aussi le rôle joué dans son œuvre par les deuils à répétition et la rivalité fraternelle. Ces deux aspects de la jalousie, et quelques-unes des expressions de leurs conflits dans la musique de Mahler, sont évoqués ici.
Wilfred Bion, philosophe des sciences
Authors: Hochmann Jacques
Published: July 2011

Résumé Bion a assimilé la démarche de connaissance à une expérience émotionnelle qui fait passer de ps (le chaos de la position schizoparanoïde) à pd (l’ordre de la position dépressive liée au choix d’un vertex). Ce travail essaie d’appliquer cette progression à la découverte de la pensée de Bion, en s’appuyant sur trois philosophes qui l’ont inspirée : Bradley, Braithwaite et Poincaré. On y voit comment Bion a tenté de donner un statut scientifique à la psychanalyse et d’appliquer la psychanalyse à une réflexion plus générale sur la philosophie des sciences.
Quand le merveilleux saisit nos sens : spectaculaire et féeries en France (XVIIe-XIXe siècle)
Authors: Martin Roxane
Published: July 2011

Résumé Cet article analyse la notion de spectaculaire au regard de quelques exemples puisés dans l’histoire des spectacles français, et plus particulièrement dans le répertoire de la féerie, entre les xvii e et xix e siècles. Il montre combien le spectaculaire, notion complexe et difficile à circonscrire, n’est pas à confondre avec le spectaculeux. Son essence réside avant tout dans l’effet qu’il produit sur le spectateur. D’Aubignac par exemple, dans sa Pratique du théâtre (1657), ne cesse de mettre en garde les auteurs sur les séductions faciles du spectaculaire, privilégiant le plaisir raisonnable, c’est-à-dire celui qui permet au spectateur de rester libre dans ses jugements et ses impressions. Copeau, puis un bon nombre des défenseurs du « théâtre d’art », condamnent également le spectaculaire, d’une part parce qu’il leur apparaît comme la caractéristique essentielle d’un théâtre bourgeois et suranné, d’autre part parce que son pouvoir éducatif passe désormais par le recul critique du spectateur. De Zola à Vilar, en passant par Brecht, le théâtre se doit d’éclairer le spectateur, de l’éduquer en lui apprenant le sens critique et la faculté d’apprécier avec intelligence les beautés des grands chefs-d’œuvre de la littérature dramatique. Le spectaculaire a toutefois pris des formes et des sens multiples selon les genres et les périodes que l’on analyse. C’est ce que cet article met en perspective, en soulignant qu’il pose toujours la même question, quelles que soient les époques : celle qui interroge la nature, le pouvoir et le rôle du spectacle.
Le groupe Galpão et le spectaculaire
Authors: Lima Evelyn
Published: July 2011

Résumé L’universalité de l’œuvre de Shakespeare est sans doute due à sa capacité de dialogue avec des cultures et des époques différentes. Cet article analyse le cas du spectacle Roméo et Juliette , mis en scène par le groupe brésilien Galpão, du Minas Gerais, au Shakespeare’s Globe Theatre, dans lequel Shakespeare ne perd ni son essence, ni sa capacité à communiquer avec le public. En témoigne celle des spectateurs anglais à vibrer aux chansons brésiliennes, ainsi que les effets plastiques et visuels qui donnent une nouvelle spectacularité à l’auteur classique. Dans ce contexte, et parce que la pièce est bien connue du public, la langue joue un rôle secondaire. Ainsi, bien que le spectaculaire conçu comme une totalité ait toujours existé au théâtre et, en particulier, dans un grand nombre des pièces de Shakespeare, le montage typiquement brésilien du groupe Galpão renouvelle la perspective : il introduit des éléments inédits de spectacularité, à la fois par la transformation d’une pièce d’un dramaturge de la Renaissance anglaise en un spectacle de cirque avec des chansons en portugais, de la musique et des vers d’auteurs brésiliens mais aussi par l’intrusion d’éléments scéniques totalement impromptus. Le Roméo et Juliette brésilien a su réunir deux mondes hétérogènes : celui de la culture hégémonique européenne et celui de la culture populaire brésilienne.
Confiance interpersonnelle et communications de travail
Authors: Karsenty Laurent
Published: July 2011

Résumé Les communications de travail mettent en jeu à la fois une relation interpersonnelle et des contenus à échanger. L’ergonomie a généralement délaissé la première dimension au profit de la seconde. Nous questionnons ici cette position à partir d’une intervention menée en contexte industriel mettant en lumière le rôle de la confiance interpersonnelle sur la transmission de consignes dans une situation de relève de poste en contexte industriel. Avant de présenter les résultats issus de cette étude, un cadre conceptuel permettant d’appréhender les questions de confiance interpersonnelle est présenté. Puis la démarche appliquée sur le terrain, fondée sur une approche participative, est décrite et les faits qu’elle a permis de mettre en évidence sont discutés. Globalement, l’étude montre que les relations de confiance ou de méfiance influencent directement la décision des opérateurs de communiquer ou non, le choix des contenus à transmettre et leur interprétation. Elle permet d’avancer que leur prise en compte peut s’avérer déterminante dans l’élaboration et l’acceptation d’un dispositif sociotechnique voué à fiabiliser la transmission de consignes.

Every year many people suffer from knee injuries. Previous studies on patients with knee injuries have shown that about 40% of knee injuries are Ligament injuries, and about 50% of the ligament injuries are the Anterior Cruciate Ligament (ACL) injuries. Along with other methods, knee arthrometers are widely used to diagnose ACL injuries. In the current research, a knee arthrometer was designed and developed to provide a reliable and repeatable measurement of knee laxity under anterior–posterior applied loads. Test–retest configurations to examine repeatability of the device resulted in less than 1.5-mm difference for more than 97% of tests under applied loads of up to 90 N. These tests included 166 tests on the left knees and 147 tests on the right knees of 37 healthy subjects. Also, this device was tested on 27 confirmed ACL ruptured patients, and the results were analyzed to find a better criterion than standard criteria to diagnose ACL rupture using knee arthrometers by finding specificity and sensitivity of the device using those criteria. Among the 20 criteria evaluated, a combination of side-to-side difference under 150 N of applied load, and CI@90-60 (compliance index calculated between 90 N, and 60 N) resulted in the best sensitivity (96.4%) and specificity (100%).
WHITE MATTER TRACTS IN FRONTO-STRIATO-THALAMIC CIRCUIT IN THE HUMAN BRAIN: A DIFFUSION SPECTRUM IMAGING STUDY
Authors: Lo Yu-Chun , Jaw Fu-Shan , Huang Su-Chun , Yeh Yu-Yang , Tseng Wen-Yih Isaac
Published: July 2011

Gender and handedness differences in cognitive functions and brain structures are well recognized. Recent research has reported different white matter structures between male and female subjects. Yet it is unknown whether the gender and handedness effects on different white matter tracts are comparable or disparate. In this study, we focus on three main tracts in the fronto-striato-thalamic circuit, namely, the cingulum bundles (CG), fornices (FXs) and anterior thalamic radiations (ATR). These are the primary connections among the frontal lobe, the limbic system, and the thalamus, integrating functions of emotion control, memory, and decision-making. A total of 40 healthy adults were recruited in this study. There was no significant difference in demographic variables between males and females. Images were acquired on a 3-T Magnetic resonance imaging (MRI) system with an eight-channel head coil. The diffusion spectrum imaging (DSI) experiment was performed by applying 203 diffusion gradient vectors. DSI maps the angular distribution of water molecule displacement by acquiring diffusion MR signals in a more comprehensive way. The theory of DSI is based on the Fourier transform relationship between diffusion MR signals and the average propagator of water molecule displacement. Isotropic spatial resolution was obtained by setting both in-plane and through-plane resolutions as 2.7 mm. A total of 45 trans-axial slices were acquired encompassing the whole brain. DSI analysis was computed based on the Fourier relationship between diffusion echo signals and the probability density function (PDF). Fiber tracking was used to define the targeted tracts. All fiber orientations of the nearest voxels were used to decide the proceeding orientation for the next step. Tracking stopped if there was no coinciding orientation in the nearest voxels. Mean path analysis, a method that projected the anisotropy of PDF [generalized fractional anisotropy (GFA)] onto a single mean path of the specific white matter tract bundle, was used to analyze subtle changes in microstructure coherence along individual tract bundles. The asymmetric differences of targeted tracts were assessed statistically by calculating GFA values and lateralization indices (LIs). The handedness factor of the LI values in CG and ATR showed a trend for significance. The gender factor of the LI values was investigated in FX also. Different white matter tract bundles manifested different degrees of gender effect on GFA distributions. Our results suggest that the gender and handedness factors should be considered when one evaluates the impairment of the fronto-striato-thalamic circuit.
Novel Watershed Algorithm for Touching Rice Image Segmentation
Authors: Kuang Fang Jun , Xu Wei Hong , Wang Yan Hua
Published: July 2011

An efficient watershed algorithm is proposed in order to solve the problem that touching rice is difficult to process during consequent image segmentation. First, the binary image is ultra-eroded by using a different structuring element to form different distance image. Second, watershed image is obtained by using the watershed algorithm. Finally, the real watershed can be extracted. Compared with other watershed algorithms, the experiment results demonstrated that this method segmented out rice successfully in the touching rice image and improved the measurement accuracy, and also overcome over-segmentation effectively.

For the purpose of discussing the potentiality of composite materials in information protecting, the microwave transmitting properties of epoxy-based carbonyl iron composite material was systematically analyzed in this report. The effective medium approximation (EMA) model was used to calculate the electro-magnetic parameters of the material, while the transmission line model was used to calculate the absorption ability of the composite material. Good agreement between calculation and experiments was obtained, which means the rationality of the describing method in this paper.
Effect of Stuffing on Microwave Properties of Composite Materials
Authors: Liu Heng , Zeng Zhao Yang , Wu Chao
Published: July 2011

As a kind of information protecting technology, material compositing becomes more and more important. The microwave properties of composite materials depend on many aspects, but stuffing is the most critical. The effect of conductive stuffing, magnetic stuffing, and the mixed stuffing are compared and analyzed in this report. It is found that conductive stuffing has the lowest absorbing behavior, while magnetic stuffing is best choice for composite. The mixing of conductive stuffing and magnetic stuffing does not result in better absorbers.
Automatic Image Annotation Using Semantic Subspace Graph Spectral Clustering Algorithm
Authors: Guo Yu Tang , Han Chang Gang
Published: July 2011

Due to the existing of the semantic gap, images with the same or similar low level features are possibly different on semantic level. How to find the underlying relationship between the high-level semantic and low level features is one of the difficult problems for image annotation. In this paper, a new image annotation method based on graph spectral clustering with the consistency of semantics is proposed with detailed analysis on the advantages and disadvantages of the existed image annotation methods. The proposed method firstly cluster image into several semantic classes by semantic similarity measurement in the semantic subspace. Within each semantic class, images are re-clustered with visual features of region Then, the joint probability distribution of blobs and words was modeled by using Multiple-Bernoulli Relevance Model. We can annotate a unannotated image by using the joint distribution. Experimental results show the the effectiveness of the proposed approach in terms of quality of the image annotation. the consistency of high-level semantics and low level features is efficiently achieved.
