Les professeurs des écoles en formation initiale et l'écriture
Authors: Balcou Maryvette
Published: April 2018

En prenant appui sur les travaux de L.S. Vygotsky, J. Goody, R. Lafont ainsi que sur ceux de M. Dabène, D. Bourgain, E. Bautier et B. Lahire, nous avons développé notre étude dans une perspective qui relève à la fois de la microsociologie et de l'anthropologie. Nous avons cherché à cerner la spécificité et les particularités du discours des futurs enseignants sur l'écriture, les liens existant entre le profil personnel et le rapport à l'écriture, ainsi que les relations entre le rapport à l'écriture et le rapport à la formation. Les données sur lesquelles notre analyse s'est appuyée (des productions écrites et des entretiens) ont été recueillies auprès d'un groupe d'étudiants de seconde année à l'I.U.F.M. d'Amiens.

L'article que nous proposons ici cherche à répondre aux questions suivantes : L'écriture des futurs enseignants présente-t-elle des particularités et lesquelles ? Quels sont les savoirs sur l'écriture dispensés à l'IUFM ? Quels sont les savoirs intégrés par les stagiaires ? Quelles sont les relations entre le rapport à l'écriture et le rapport à la formation ? Quels sont les lieux de résistances ? Comment les stagiaires parlent-ils de leurs pratiques d'écriture ?

Nos analyses permettent de souligner le fait que l'écriture est un lieu de tensions entre les représentations (individuelles et socio-culturelles) de l'écriture et le souci de prendre en compte l'enseignement dispensé par l'IUFM. Elles mettent l'accent sur les effets positifs de la formation ainsi que sur la prégnance des questions professionnelles dans les discours des PE2 sur l'écriture. Nous pointons également des lieux et phénomènes de résistances, lesquels anéantissent parfois tout ou partie des efforts consentis par les formateurs.
Une argumentation orale dans une démarche scientifique au cycle 3
Authors: Garcia-Debanc Claudine
Published: April 2018

Formulating an argument orally as part of a scientific process in the third cycle of primary school (8 to 11). What reformulations and connectives tell us about the specificities of interaction at school.

Claudine GARCIA-DEBANC, Cerf and IUFM de Toulouse -INRP "Oral".

The study is based on the analysis of an argumentative exchange at the beginning of a sériés of lessons in CM1 (9 year olds). Using individual procedures which are pooled together, the pupils are led to ask themselves questions about the relations between the digestive and circulatory systems and to com pare their different representations of these systems. After giving a summary of the constituent elements of a situation where an argument is formulated, the article situâtes the interaction in relation to the different types of argumentation which occur in the third cycle of primary school. An analysis of a short extract from the corpus deals successively with the status and role of disagreements within the argumentative process, reformulations and connectives within the same process. The analysis aims to create closer links between some specificites of oral interaction at school.
Essayer d'écrire dès l'École maternelle : un risque raisonné porteur d'apprentissage

Published: April 2018

Attempting to write from as early as nursery school : a carefully thought out risk which can lead to learning.

Brigitte CALLEJA, Chantai CLOIX and Jacques RILLIARD, IUFM de Bourgogne-INRP PROG.

Producing written work at the start of the second cycle (5 year olds) causes much apprehension in teachers due to the possibility of failure to which the pupils are exposed. This paper illustrates an appraisal of the possible risks which was made by two female teachers by showing how they use the performances of two children with learning difficultés as a basis for getting them to make progress. The accounts of the peculiar paths taken by these two children reveal, at different junctures, events which are comparable from the point of view of the progressiveness of the learning. These events show that the pupils become aware of certain aspects of written language and that they also take the tension out of the risks of making mistakes. For the teacher, these are key moments in the learning process which he takes into account when teaching.
Et si l'entrée dans la culture de l'écrit se faisait comme du miel ?
Authors: Defrance Marie-Alix
Published: April 2018

And what if the passage into the culture of written language were a natural process ?

Marie-Alix DEFRANCE, IUFM de Versailles-INRP PROG.

The Ministry of Education directives state that the mission of primary schools is to guide the pupils towards the culture of written language and the day-to-day practices of teachers aim for this. The paper attempts to show how the 'PROG' research differs from these practices in that field : the aim of this research is not strictly the culture in written language but it puts forward the hypothesis that attaining this culture cornes about quite naturally when children do language and, to a greater extent, cognitive activities concerning the written language over a very long period of time (over the course of the three years which make up the cycle). The objective which the 'PROG' research set for itself was for the children to build up for themselves skills and représentations in the four main fields which are : the use of language in ail its dimensions, understanding the written language, producing written work, and manipulating the written language so as to discover how it functions. The paper shows traces of this growing culture, and then shows, via research practices in all four fields, how each child creates for himself the roots of his own culture in the written language by sharing his representations with his friends, family and teachers.
Une intervention à visée cognitive en Grande section de Maternelle : ses effets de transfert sur l'apprentissage de la lecture à l'École élémentaire
Authors: Cèbe Sylvie
Published: April 2018

A cognitive training session for 5 year olds : its transferring effects when these pupils are learning to read, from 6 to 8 years old.

Sylvie CEBE, Psychologie du développement, Université de Provence.

Two distinct courses of action can be taken when preparing the pupils for the fundamental learning of written ianguage : the first, didactic (given priority in this review), which concerns knowledge and savoir-faire relating to the Ianguage, and the second, cognitive, which centres upon the acquisition of general cognitive and meta-cognitive skills. Our work cornes within the framework of the latter. We believe that it is necessary to modify the learning conditions in which the pupils are placed (and especially pupils from working-class backgrounds) in order to improve the way they function from an intellectual point of view and thus make learning to read easier. That is what we attempt to do by putting forward a cognitive training session for 5 year olds. It aims at getting the pupils to acquire and put into practice logical frameworks of thought since their effective learning of the specific contents of school teaching depends upon these frameworks. After describing the psychological and pedagogical principles of our training session as well as the way in which we put them into practice, we will present the transferring effects of this session upon the same pupils when learning to read between the age of 6 and 8.
Apprendre à lire : de la pratique à la théorie
Authors: Goigoux Roland
Published: April 2018

Les injonctions de l'Observatoire national de la lecture, qui visent à proscrire « l'interrogation du contexte » comme aide à l'identification des mots au début de l'apprentissage de la lecture, sont ici vivement contestées en prenant appui sur les résultats de trois études récentes. La « dépendance contextuelle », loin d'être une caractéristique des plus faibles lecteurs de CP-CE1, apparait comme une constante développementale chez tous les élèves, y compris ceux qui vont devenir les meilleurs lecteurs.
L'objet enseigné : vers une méthodologie plurielle d'analyse des pratiques d'enseignement en classe
Authors: Canelas-Trevisi Sandra , Moro Christiane , Schneuwly Bernard , Thévenaz-Christen Thérèse
Published: April 2018

Partant du constat fait par Hélène Romian de la nécessité de mieux connaitre ce qui se passe dans les classes de français, les auteurs observent d'abord un changement de paradigme d'une didactique d'intervention à une didactique descriptive, changement qui permet mieux de répondre à la nécessité constatée. Ils esquissent ensuite une manière d'y répondre à travers un travail sur les mécanismes de transposition en œuvre dans la classe lors de la construction interactive des objets enseignés. Pour mieux décrire et comprendre ces mécanismes, une approche pluridisciplinaire s'avère nécessaire. Trois méthodologies complémentaires, actuellement en construction, illustrent cette approche. La première utilise le concept d'isotopie sémantique proposé par Rastier pour comprendre les contextes conflictuels dans lesquels enseignants et élèves construisent les objets enseignés. La deuxième se penche sur les gestes d'enseignement pour reconstruire finement le guidage effectué par l'enseignant pour permettre la construction des objets d'enseignement. Sémiotique, la troisième observe l'évolution de la signification des objets, par exemple au moment de leur mise en scène.
Le cycle de vie du Cerisier : une narration « scientifique » ?

The life cycle of the Cherry tree : a scientifîc narration ?

Élisabeth BAUTIER, ESCOL, Danièle MANESSE, INRP, Brigitte PERTERFALVI, INRP, Anne VERIN, INRP.

Within the context of a piece of research into the forms and functions of written work in science, this article proposes to observe behavioural patterns in writing used spontaneously by pupils in 6ème (Year 7) when given a scientific type instruction in a non-scientific framework.

We were able to do this thanks to the national tests which are given to Year 7 pupils each year. In 1997, this evaluation included an item which required the pupil to translate a scientific diagram outlining the life cycle of the Cherry tree into a written account of this same process. The pupils were thus asked to produce a sort of "scientific" narration, the différent stages of which had to be linked together.

Firstly, we examine the difficultes and the ambiguities of the task, the criteria which must be met in order for work produced by a pupil to be considered a "success" scientifically speaking, which therefore makes it different from a traditional type of narration, such as pupils produce in French. Next, we examined the work produced by a class of pupils from a school in an Educational Priority Area, the main elements of which are included in this paper ; this enabled us to identify différent behavioural patterns in writing, reflecting différent "positions" in the relationship to scientific knowledge.
Les consignes au cœur de la classe : geste pédagogique et geste didactique

Instructions at the heart of classroom activity : a pedagogical act and a didactic act.

Jean-Michel Zakhartchouk, IUFM de Picardie.

The aim of this paper is to examine certain aspects of a fundamental didactic act : formulating and passing on instructions. Thinking about how pupils understand classroom instructions is now an intégral part of the teacher's mis sion, which is a relatively recent development. However, the conditions needed for instructions to become learning tools still have to be defined.

We intend to list some of these conditions : adapting the instructions to the specific aim of the task (to this end, we can build up typologies of instructions) ; thinking about how the instructions are communicated in class ; "juggling" between their importance as an aid and the need to let the pupils digest and understand them.

Ongoing work on the understanding of instructions still has to be integrated into the didactics of teaching. We put forward a few suggestions : use of meta-cognition and création of common classroom tools, joint reflection with the pupils on the very significance of instructions at school. Work in live situations can be supplemented by practice activities or by studying the school instructions themselves.

The paper concludes by expressing the wish that more research be carried out in an area on which success at school depends. A few topics are suggested.
Cahiers et classeurs : les supports ordinaires du travail scolaire
Authors: Chartier Anne-Marie , Renard Patricia
Published: April 2018

L'article fait l'hypothèse que les choix des enseignants concernant l'utilisation des cahiers scolaires ont des enjeux pragmatiques (sur l'organisation du travail), pédagogiques (sur la gestion des traces écrites et leur évaluation) et cognitifs (sur la classification des savoirs «en acte » ainsi effectuée). Après s'être interrogé sur les limites inhérentes à une enquête déclarative (auprès de 87 maîtres de l'école élémentaire), l'article commente les données recueillies, puis s'intéresse à ce qui motive les choix des classeurs ou des cahiers. Il synthétise les réponses des maîtres sur la longueur et la durée d'écriture quotidienne, le temps requis pour les corrections, avant de se focaliser sur les écrits dans l'enseignement du français. Il essaie de dégager des modèles d'organisation en concurrence, soit centrés sur les matières d'enseignement (modèle secondaire), soit centré sur le travail (modèle primaire, distinguant les supports des textes à stocker des supports pour les exercices routiniers).
De quelques propriétés d'une pratique de lecture extrascolaire : le courrier des lecteurs du journal Astrapi
Authors: Penloup Marie-Claude
Published: April 2018

L'existence de pratiques d'écriture extrascolaires commence à être admise mais un gros travail reste à faire de description fine de ces pratiques, de connaissance du régime d'écriture sous lesquelles elles sont produites et de réflexion sur l'intérêt didactique de cette description. Nous envisageons ici une pratique mal connue : l'écriture de lettres à un journal dont on est le lecteur. Ce courrier de jeunes lecteurs s'avère être à l'initiative des enfants mais il n'en a pas pour autant de caractère très inventif et créatif. On observe au contraire qu'il se construit en interaction avec le journal et les normes que celui-ci met en place. Au plan didactique, l'observation du corpus conduit à dégager deux axes de réflexion : le premier porte sur l'existence et la prise en compte d'une pédagogie extrascolaire de l'écriture ; le second sur le statut des savoirs «cachés» dans les pratiques extrascolaires.
Des situations problèmes pour la verbalisation : difficultés à dire et travail de l'énonciation
Authors: Nonnon Elisabeth
Published: April 2018

Exploiter les situations d'apprentissage de la classe dans le cadre d'une pédagogie intégrée de l'oral suppose de savoir discerner en quoi elles peuvent être définies comme tâches langagières, lieu d'un travail énonciatif non précodé, et pas simplement mise en œuvre de routines et de stratégies acquises. Parmi les contraintes qui rendent problématique l'activité énonciative, l'article s'attache particulièrement à celles qui tiennent aux caractéristiques du référent, en analysant notamment les problèmes que pose le choix d'une perspective et d'un point de repère pour la référenciation. Prendre en compte les variables didactiques liées à la complexité du référent et en jouer dans la définition des situations permet de moduler les tâches fonctionnelles de langage en fonction du moment dans l'apprentissage et des acquis des élèves, pour assurer à la fois une différenciation et une variation dans la reprise des mêmes conduites dans d'autres contextes.
Suffit-il de parler pour apprendre ? Dimensions didactiques de la mise à distance des pratiques langagières
Authors: Delabarre-Bulot Evelyne , Treignier Jacques
Published: April 2018

Une équipe mixte de recherche INRP -CNRS UMR 6065 Dyalang Rouen s'est intéressée aux apprentissages langagiers opérés par des élèves d'École élémentaire, dans des assemblées scolaires représentatives : conseils de classes et parlements d'une École élémentaire drouaise, constituée de cinq classes situées en zone d'éducation prioritaire et accueillant majoritairement une population scolaire d'origine marocaine. Constatant que ces apprentissages étaient très souvent implicitement organisés, avec les conséquences sociolinguistiques, psycholinguistiques et didactiques que chacun peut imaginer, l'équipe a favorisé un retour réflexif sur la communication, par le biais de débats, d'enquêtes après visionnement d'enregistrements vidéo de ces deux types d'assemblées ayant eu lieu dans l'école. Elle met en évidence tout l'intérêt, pour les enseignants tout comme pour les élèves, de ce retour réflexif sur les activités vécues ou observées. Pour les premiers, il apporte une meilleure connaissance et une plus grande prise en compte des représentations et des stratégies des élèves. Pour ces derniers, il facilite la clarté cognitive, la construction du sens des activités et du savoir, l'implication dans les apprentissages, l'opérativité et la stabilité des acquisitions.
Déficits herméneutiques lors de l'acquisition de la compétence narrative. La sous-exploitation des interactions orales aux cycles 1 et 2
Authors: Rabatel Alain
Published: April 2018

Cet article analyse un certain nombre de dysfonctionnements de nature à entraver l'acquisition d'une compétence narrative et d'une compétence oralo-graphique, chez de jeunes enfants des cycles 1 et 2. Les séquences analysées se fixent comme objectif l'initiation au récit. Cette initiation, conduite essentiellement à l'oral, hésite pourtant sur la hiérarchisation des activités. En effet, on peut se demander si l'objectif recherché était bien l'initiation au récit, notamment à travers la «lecture de l'image» et la dictée à l'adulte, ou si le récit n'était pas qu'un prétexte au développement de la compétence oralo-graphique. Il résulte de cette contradiction non résolue un déficit herméneutique affectant la représentation du récit écrit (et de sa signification), sous-estimant les spécificités du récit oral et entravant les échanges langagiers, qui portent insuffisamment sur la signification et la dimension interprétative du récit co-produit par les élèves.
Les effets d'un instrument d'écriture à l'épreuve de la recherche. Deux ou trois choses que l'on sait ou que l'on ne sait pas sur le traitement de texte
Authors: Plane Sylvie
Published: April 2018

Cette contribution prend comme point de départ les conclusions des historiens de la culture et des ergonomes qui ont montré que les instruments d'écriture jouaient un rôle dans l'évolution des pratiques d'écriture. Elle pose donc comme hypothèse que le traitement de texte, en tant qu'outil graphique et scriptural, est un instrument susceptible d'exercer une influence sur l'écriture et examine les résultats dégagés des recherches en fonction de leur degré de certitude. Les résultas les mieux établis concernent le rôle positif exercé par le traitement de texte sur la motivation des scripteurs. En revanche, l'effet du traitement de texte sur les processus rédactionnels n'a pas pu être mis en évidence de façon incontestable, pour des raisons qui tiennent, d'une part, à différents types de cause qui sont analysées dans cet article, mais aussi, d'autre part, aux conceptions de l'écriture qui ont présidé aux expérimentations. Enfin, l'article recense cinq points sur lesquels il appelle le développement de recherches qui éclaireraient la connaissance lacunaire que l'on a actuellement de l'écriture sur traitement de texte.
Écrire et réécrire au cycle 3 : l'effet des mots clés sur la réécriture, avec et sans assistance informatique

Write and rewrite in cycle 3 (8 to 11 years old) : the effect of keywords on rewriting, with and without computer's help.

Jacques Crinon, Denis Legros & Brigitte Marin, Coditexte / CNRS-ESA7021 (ParisVIII), IUFM de Créteil.

The present study faits within the framework of researches that allowed perfecting a software to help rewriting and to compare rewritings of stories of Personal experience by pupils of cycle 3 whether they benefited or not of computerized help. The pupils of the group that take notes in the computerised database of textual resources rewrite more than the pupils of the group that benefits of textual resources presented on paper. Besides, their additions, more important on the semantic level, belong to the macrostructure of the text.

We tried to understand the reasons of these results by analysing the role taken by the access to the resources through keywords. 112 pupils, shared in four groups, have written, then rewritten a story : the textual resources were presented on paper or on a computer ; the consultation was done in a linearly process or with the help of keywords describing these texts' universe.

We have compared the number and the «relevance » of the additions made according to the group. The results do not show any quantitative differences between the participants of the groups that used keywords and the others. On the other hand the groups with keywords produce additions less relevant when using paper resources and more relevant when using computer resources.

The number of texts available and the possibility for the pupil to find resource texts compatible with the text he is writing seem determining. The presence of keywords allows, on the computer, the efficient circulation through an important corpus. So is the function of the tool underscored : open new possibilites, in a configuration where interact numerous factors.
Inverse proximity effect in semiconductor Majorana nanowires
Authors: Kopasov Alexander A , Khaymovich Ivan M , Mel'nikov Alexander S
Published: April 2018

We study the influence of the inverse proximity effect on the superconductivity nucleation in hybrid structures consisting of semiconducting nanowires placed in contact with a thin superconducting film and discuss the resulting restrictions on the operation of Majorana-based devices. A strong paramagnetic effect for electrons entering the semiconductor together with spin–orbit coupling and van Hove singularities in the electronic density of states in the wire are responsible for the suppression of superconducting correlations in the low-field domain and for the reentrant superconductivity at high magnetic fields in the topologically nontrivial regime. The growth of the critical temperature in the latter case continues up to the upper critical field destroying the pairing inside the superconducting film due to either orbital or paramagnetic mechanism. The suppression of the homogeneous superconducting state near the boundary between the topological and non-topological regimes provides the conditions favorable for the Fulde–Ferrel–Larkin–Ovchinnikov instability.

We explore how the group environment may affect the evolution of star-forming galaxies. We select 1197 Galaxy And Mass Assembly groups at 0.05 ≤ z ≤ 0.2 and analyze the projected phase space (PPS) diagram, i.e., the galaxy velocity as a function of projected group-centric radius, as a local environmental metric in the low-mass halo regime 1012 ≤ (M
200/M
⊙) < 1014. We study the properties of star-forming group galaxies, exploring the correlation of star formation rate (SFR) with radial distance and stellar mass. We find that the fraction of star-forming group members is higher in the PPS regions dominated by recently accreted galaxies, whereas passive galaxies dominate the virialized regions. We observe a small decline in specific SFR of star-forming galaxies toward the group center by a factor ∼1.2 with respect to field galaxies. Similar to cluster studies, we conclude for low-mass halos that star-forming group galaxies represent an infalling population from the field to the halo and show suppressed star formation.
A New Desalination Pump Helps Define the pH of Ocean Worlds
Authors: Levi A. , Sasselov D.
Published: April 2018

We study ocean exoplanets, for which the global surface ocean is separated from the rocky interior by a high-pressure ice mantle. We describe a mechanism that can pump salts out of the ocean, resulting in oceans of very low salinity. Here we focus on the H2O–NaCl system, though we discuss the application of this pump to other salts as well. We find our ocean worlds to be acidic, with a pH in the range of 2–4. We discuss and compare between the conditions found within our studied oceans and the conditions in which polyextremophiles were discovered. This work focuses on exoplanets in the super-Earth mass range (∼2 M
⊕), with water composing at least a few percent of their mass. However, the principle of the desalination pump might extend beyond this mass range.

For a sample of star-forming galaxies in the redshift interval 0.15 < z < 0.3, we study how both the relative strength of the active galactic nucleus (AGN) infrared emission, compared to that due to the star formation (SF), and the numerical fraction of AGNs change as a function of the total stellar mass of the hosting galaxy group (

) between 1010.25 and 1011.9
M
⊙. Using a multicomponent spectral energy distribution SED fitting analysis, we separate the contribution of stars, AGN torus, and star formation to the total emission at different wavelengths. This technique is applied to a new multiwavelength data set in the SIMES field (23 not-redundant photometric bands), spanning the wavelength range from the UV (GALEX) to the far-IR (Herschel) and including crucial AKARI and WISE mid-IR observations (4.5 μm < λ < 24 μm), where the black hole thermal emission is stronger. This new photometric catalog, which includes our best photo-z estimates, is released through the NASA/IPAC Infrared Science Archive (IRSA). Groups are identified through a friends-of-friends algorithm (∼62% purity, ∼51% completeness). We identified a total of 45 galaxies requiring an AGN emission component, 35 of which are in groups and 10 in the field. We find the black hole accretion rate (BHAR) ∝ (

and (BHAR/SFR) ∝ (

A Novel Self-Organization Approach for Stigmergy Based Cloud Service Composition
Authors: Zertal Soumia , Batouche Mohamed , Benharkat Aïcha-Nabila , Benfenatki Hind
Published: April 2018

This article describes how cloud computing and the convergence toward “Everything as a service” have encouraged the proliferation of services ready for use. These facilities have increased the requests of the companies for the development of the applications. In this context, where the reusability is needed, cloud service composition techniques are widely used. However, traditional centralized service composition techniques are not sufficient to address the needs of applications in highly dynamic and open environments. Early attempts for service composition models in decentralized environments have been proposed, but they are limited by their ability to adapt when deploying in highly dynamic and open environments. In this paper, the authors use Stigmergic-based self-organization mechanisms inspired from nature to model the decentralized service interactions and handle service composition in highly dynamic and open environments.
Best Features Selection for Biomedical Data Classification Using Seven Spot Ladybird Optimization Algorithm
Authors: Bidi Noria , Elberrichi Zakaria
Published: April 2018

This article presents a new adaptive algorithm called FS-SLOA (Feature Selection-Seven Spot Ladybird Optimization Algorithm) which is a meta-heuristic feature selection method based on the foraging behavior of a seven spot ladybird. The new efficient technique has been applied to find the best subset features, which achieves the highest accuracy in classification using three classifiers: the Naive Bayes (NB), the Nearest Neighbors (KNN) and the Support Vector Machine (SVM). The authors' proposed approach has been experimented on four well-known benchmark datasets (Wisconsin Breast cancer, Pima Diabetes, Mammographic Mass, and Dermatology datasets) taken from the UCI machine learning repository. Experimental results prove that the classification accuracy of FS-SLOA is the best performing for different datasets.
Evaluation of Telemedicine Systems User Satisfaction in Developing Countries
Authors: Edoh Thierry , Pawar Pravin Amrut , Kora Ahmed Dooguy
Published: April 2018

This article describes how in developing countries, the work on regulatory aspects of telemedicine systems and applications is still in infancy. During our literature review and on-site research in Sub-Saharan Africa, we could not point out any work on measuring the quality of service (QoS) and quality of experience (QoE or QoX) provided by the telemedicine systems, thus making it impossible to measure the overall level of system user satisfaction in Sub-Saharan Africa. Therefore, we conducted a qualitative and quantitative study to measure network QoS performance and end-user QoE perception of telemedicine systems using publicly accessible conversation tool Skype in Mali and Senegal. The results show that about 75% of the users were satisfied with the quality of teleconsultation service provided and 60% of the users have good impression on the network performance. Based on obtained results, we propose KPIs such as global QoS for measuring QoS and propose a mathematical formula to predict the corresponding QoE, since there exists a relationship between QoS and QoE.

Kinect-Based Limb Rehabilitation Methods
Authors: Yang Yongji , Xiao Zhiguo , Jiang Furen
Published: April 2018

Within the context of health informatics, this article discusses how real-time information of human skeleton movements can be conveniently captured via the use of Kinect-based deep sensor. It highlights an effective action recognition method, using Unity3D to form virtual models of characters and scenes. Kinect somatosensory cameras can now identify one's motion data and provide feedback on the virtual role model to complete the avatar drive. This is to achieve real-time simulation modeling as well as drive operation instructions based on the design and identification verification to complement limb rehabilitation. The hardware of such a health informatics-related system is simple, inexpensive, and highly meaningful in term of augmenting user experience. In conclusion, the suggested approach can contribute significantly towards aiding physical rehabilitation therapy
Anaphora Resolution
Authors: Gros Daniel , Habermann Tim , Kirstein Giulia , Meschede Christine , Ruhrberg S. Denise , Schmidt Adrian , Siebenlist Tobias
Published: April 2018

This article analyses the effect of anaphora resolution on information retrieval performance for systems with relevance ranking. It will be investigated if the Mean Average Precision of a retrieval system is improved after an intellectual replacement of all anaphors in a corpus with various texts. These texts mostly consist of news stories and fairy tales, thus covering two varying genres with different amounts of anaphors. A model retrieval system is developed using Lucene to measure the effects of anaphora resolution. Different queries are used and the rankings are analysed in order to show the changes induced by the anaphora resolution. In addition, approaches of automated anaphora resolution are considered. It turns out that the Mean Average Precision improves noticeably by 36% after the anaphora resolution. Thus, it is highly recommended to improve existing approaches of automated anaphora resolution in the future as current attempts do not yet yield satisfying results.

Predict Coordinated Development Degree of County Eco-Environment System Using GA-SVM
Authors: Zhao Jing , Jin Zhen
Published: April 2018

This article describes how economic development has had a significant impact on the environment. County eco-environment coordinated development has contributed to regional coordinated development in China. A support vector machine (SVM) model was constructed to classify and predict coordinated development degrees of the county eco-environment system. In order to improve the discrimination precision of SVM in classification, a Genetic Algorithm (GA) was used to optimize SVM parameters in the solution space. The method was compared with artificial neural network, decision tree, logistic regression and naive Bayesian classifier regarding coordinated development degree of county eco-environment system prediction for Guanzhong urban agglomeration. It found that the method has the best accuracy rate, hit rate, covering rate and lift coefficient.

Authors: Jagatheesan K. , Anand B.
Published: April 2018

In this article, the optimal gain value of classical controller gain values is obtained by using different performance indices in Automatic Generation Control. These are interconnected by the three areas of a hydro-thermal power system. The thermal and hydro areas are incorporated with a reheat turbine and a mechanical governor, respectively. The current article was created to select a suitable technique for the tuning of controller gain, when 1% of a step load is given to the thermal area (Area 1). The performance of several controllers, such as Integral (I), Proportional-Integral (PI), and Integral-Derivative (ID) were evaluated and were compared to the cases of with and without Generation Rate Constraint (GRC) non-linearity. The classical controller gain value optimization was performed using the Integral Time Square Error (ITSE), Integral Square Error (ISE) and Integral Time Absolute Error (ITAE) performance indices. The minimum optimal value of controller gain normally offers better dynamic response. The obtained results established that the optimization based on the ITAE-PI controller always guarantees superior dynamic performances compared to other indices and controllers.

Published: April 2018

The amount of malware has been rising drastically as the Android operating system enabled smartphones and tablets are gaining popularity around the world in last couple of years. One of the popular methods of static detection techniques is permission/feature-based detection of malware through the AndroidManifest.xml file using machine learning classifiers. Ignoring important features or keeping irrelevant features may specifically cause mystification to classification algorithms. Therefore, to reduce classification time and improve accuracy, different feature reduction tools have been used in past literature. Community detection is one of the major tools in social network analysis but its implementation in the context of malware detection is quite rare. In this article, the authors introduce a community-based feature reduction technique for Android malware detection. The proposed method is evaluated on two datasets consisting of 3004 benign components and 1363 malware components. The proposed community-based feature reduction technique produces a classification accuracy of 98.20% and ROC value up to 0.989.

In this research, mechanical properties of bone cement containing micro-and nanohydroxyapatite (HAp) particles were studied. The bone cement was prepared from mixing between polymethyl methacrylate (PMMA) and methyl methacrylate (MMA). Hydroxyapatite powder was prepared from bovine bone. The bone was heated in hot water at 200 oc for the elimination of tissue, after which the bone was dried and calcined at 800 oc for 3 hrs. The calcined bone than was crushed into powder and ball-milled for 24 hrs. The micro-HAp particle was then obtained. The micro particles were then further milled employing the Vibro-milling machine for 2 hrs. The micro-and nanoHAp sizes are about 0.5 μm and 140 nm, respectively. The both size powders were treated with γ-methacrylic-propyl-tri-methoxy silane. The acetic acid was added to control the pH of the solution, until it reached 2.9 before they were mixed into the bone cement with equally wt%. The mixture was casted using the 304 stainless steel mold in order to obtain a cylindrical shape. The low vacuum scanning electron microscope (LV-SEM) and x-ray diffractometer (XRD) were employed to characterize the samples. The porosity of PMMA could be reduced by HAp particle additives. From compressive strength test, it was found that the mixture of bone cement and nanoHAp particle has shown higher compressive strength than pure PMMA bone cement that affected by porosity reduction and force distribution by HAp particles.

The aim was to investigate the relation between micromorphology of porosity and electrical resistance of dental luting cements. Five dental luting cements were evaluated: zinc phosphate, glass ionomer, and three types of resin luting cements. Porosity of the specimen was analyzed by micro-CT and electrical resistance of cement was measured at voltage of 125 V up to 30 days and solubility of each specimen was calculated. It showed that the resin luting cements provided the highest electrical resistance regardless of amount of porosity. Zinc phosphate and glass ionomer had high porosity and the lowest resistance (14 and 3 kΩ, respectively). It was found that the electrical resistance of luting cement was not directly affected by the amount of porosity, but it seems to be related to pore connection. There is no correlation between electrical resistance and percentage of porosity but the morphology of porosity may have an influence on the electrical property of luting cement. Models of pore connection were proposed to explain the electrical resistance of luting cement.

Utilization of photocatalytic properties of materials can be perceived through a wide range of applications, such as anti-bacterial, water treatment, and self-cleaning materials. It has been established that doping can result in alteration of photocatalytic activities. This study aimed at studying effects of tin concentration on chemical composition, microstructure, band gap energy, and photocatalytic activities of tin-doped titanium dioxide powder synthesized by solution combustion technique. Experimental results revealed that concentration of tin significantly influenced chemical composition of the powders. A semi-quantitative analysis indicated that tin oxide secondary phase increased from 11 to 23 wt%, as the Sn increased from 2.5 to 10 mol%, respectively. Tin concentration, nevertheless, did not significantly influence microstructure of the powders. All powders had average particle size ranging from 13.1 to 13.4 nm, which agglomerated into clusters with average sizes ranging from 103 to 140 nm. A slight increase of band gap energy was observed at higher tin concentration. The most prominent photocatalytic activities, determined from decomposition of methylene blue, was found in the titanium dioxide powder with 2.5 mol% Sn.

Clinical evaluation and ultrasound examination are the first steps in the evaluation of a patient with a swelling of the parotid region. After the detection of a nodular lesion, cytological or histological confirmation is usually performed to achieve the diagnosis, while the choice of cross-sectional imaging (computed tomography scan and magnetic resonance imaging) may significantly vary from one physician to another, on the basis of the degree of confidence that both radiologist and surgeon have with this kind of imaging. This work focuses on some essential “reporting points” in cross-sectional imaging evaluation of parotid nodules, chiefly helpful to the radiologist when the ultrasonography assessment is considered incomplete and requires a further evaluation.
