Digitalisierung in der Gesundheitsversorgung – vom Hype zur produktiven Anwendung
Authors: Knöppler Karsten , Bottling Holger , Caumanns Jörg , Hartge Florian , Morgenstern Kai-Uwe , Eggers Thies
Published: March 2020

Marktentwicklung und aktuelle Gesetzgebung im Kontext digitaler Gesundheitsanwendungen und digitaler Vernetzung im Gesundheitswesen befördern auf eine neue Art und Weise die Integration von Versorgung sowie von Verwaltungsprozessen der GKV und Gesundheitshandeln der Bürger. Zudem ebnen sie den Weg für die digitale Erbringung von bisher analogen Leistungen und neuartigen digitalen Leistungen. Mit dieser Entwicklung scheint ein substanzieller Produktivitätssprung in der Gesundheitsversorgung durch Digitalisierung möglich. Es stellt sich die Frage, was davon Hype ist und wo Optionen für eine produktive Anwendung in der Versorgung bestehen.

In the recent years, researchers have sophisticated the synthesis of neural networks depending on the wavelet functions to build the wavelet neural networks (WNNs), where the wavelet function is utilized in the hidden layer as a sigmoid function instead of conventional sigmoid function that is utilized in artificial neural network. The WNN inherits the features of the wavelet function and the neural network (NN), such as self-learning, self-adapting, time-frequency location, robustness, and nonlinearity. Besides, the wavelet function theory guarantees that the WNN can simulate the nonlinear system precisely and rapidly. In this chapter, the WNN is used with PID controller to make a developed controller named WNN-PID controller. This controller will be utilized to control the speed of Brushless DC (BLDC) motor to get preferable performance than the traditional controller techniques. Besides, the particle swarm optimization (PSO) algorithm is utilized to optimize the parameters of the WNN-PID controller. The modification for this method of the WNN such as the recurrent wavelet neural network (RWNN) was included in this chapter. Simulation results for all the above methods are given and compared.

: After the outbreak of 2019 novel corona virus infection in China, we have the outbreak of disease in Iran and until March 05, 2020 have been reported a total number of confirmed cases more than 3500 and approximately 3.3% deaths. The corona virus disease 2019 (COVID-19) infection as a newly emerging disease in East Asia has caused a great challenge in managing the patients and controlling the disease especially in children. This algorithm is based on the standard diagnosis and treatment strategies for pediatric viral infections and available strategies to prevention of COVID-19 infection. It is hoped that with international co-operation, this global dilemma will end with the least burden of disease. Due to the lack of scientific evidences in children, this algorithm is essential for decision making.
Les paradoxes identitaires des hipsters : quelles stratégies pour les marques ?
Authors: Tesio Pauline , Kessous Aurélie , de Barnier Virginie
Published: March 2020

Cet article vise à décrypter les paradoxes identitaires des contre-cultures postmodernes afin qu’ils soient compris et utilisables par les marques. Considérant comme terrain de recherche la contre-culture hipster , il tente de répondre à la problématique suivante : comment les marques traduisent-elles les paradoxes identitaires des contre-cultures en leviers d’action marketing ? Une étude qualitative par entretiens permet d’appréhender le décalage entre la façon dont les hipsters se perçoivent et celle dont ils sont perçus via 6 oppositions : 1. Absence de catégorisation vs membres d’une communauté ; 2. Marginaux vs bourgeois ; 3. Avant-gardistes vs trendy  ; 4. Libres vs prisonniers de leurs codes ; 5. Autodidactes vs apprentis ; 6. Passionnés vs indifférents. De ces oppositions découlent des recommandations managériales à destination des marques souhaitant cibler ce profil de consommateurs et plus globalement, les adeptes des contre-cultures de consommation.
« L’histoire est là, et il faut la digérer … il faut "la rendre conte" » : réflexions autour de la mise en fiction de l’histoire dans le roman postcolonial
Authors: Mbondobari Sylvère
Published: March 2020

L’une des conséquences des lois mémorielles de 2001 et de 2005 en France fut une réflexion à propos des conditions de possibilité d’une écriture croisée de l’histoire des conquêtes coloniales en Afrique francophone. Le présent article propose dans une première partie une étude des modalités d’inscription de l’histoire coloniale dans LeRoi de Kahel et de Le Terroriste noir de Tierno Monénembo à partir des notions de « conte » et de « rendre compte » des évènements du passé. La seconde partie porte sur Madagascar, 1947 où l’écrivain malgache Jean-Luc Raharimanana mène une réflexion sur les modalités d’une réappropriation de l’histoire coloniale au nom du devoir de mémoire.
Les morts littéraires de Jean de Brébeuf : l’histoire coloniale et l’imaginaire canadien
Authors: Morris Paul D.
Published: March 2020

La vie et surtout la mort du missionnaire jésuite Jean de Brébeuf en Huronie au XVIIe siècle occupent une place complexe et évolutive dans l’imaginaire canadien. Un personnage clé au moment du contact initial entre les colonisateurs européens et les peuples indigènes de l’Amérique du Nord, Brébeuf fut destiné à devenir encore plus grand que le rôle historique qu’il a joué dans sa vie. Avec sa mort, Brébeuf entra dans le domaine des représentations mythiques du Canada. L’article actuel cherche à tracer la trajectoire historique de la place de Brébeuf dans les littératures d’expression anglophone et francophone au Canada. Faisant référence à une lecture de trois textes littéraires représentatifs, l’article suggère que la représentation littéraire de Brébeuf peut être étroitement alignée sur des conceptions historiquement changeantes du Canada selon des compréhensions francophone, anglophone et autochtone de l’identité nationale.
Obstacles et facilitateurs à l’inclusion et à la participation sociale des personnes ayant des incapacités intellectuelles

Published: March 2020

Cette recherche a pour objectif d’explorer des obstacles et des facilitateurs reliés à l’inclusion et à la participation sociale de personnes ayant des incapacités intellectuelles issues des services d’intégration en emploi d’un Centre intégré de santé et des services sociaux. Au total, 27 participants ont été rejoints par cette étude au moyen de groupes de discussion et d’entrevues individuelles auprès de personnes ayant des incapacités intellectuelles, de parents, de professionnels enseignants, d’intervenants du réseau de la santé et des services sociaux, d’employés d’un organisme de soutien à la personne et sa famille, ainsi que d’employeurs. Les résultats mettent en évidence 1) des facteurs personnels (compétences sociales, capacité d’adaptation, autonomie), 2) des facteurs environnementaux liés au microenvironnement personnel (style parental, pratiques parentales), au mésoenvironnement communautaire (contextes scolaire, professionnel et communautaire inclusifs et pratiques des professionnels) et au macroenvironnement sociétal (orientations politiques et des services) en lien avec l’inclusion et la participation sociale de personnes ayant des incapacités intellectuelles.
L’enseignement de l’histoire nationale au Québec à travers ses recommandations curriculaires : une analyse lexicométrique
Authors: Moreau Daniel , Smith Jonathan
Published: March 2020

Cet article présente les résultats d’une analyse de contenu de nature lexicométrique, réalisée sur un corpus de textes composé de rapports du Groupe de travail sur l’enseignement de l’histoire (1996), du Groupe de travail sur la réforme du curriculum (1997) et du Comité d’experts chargé d’étudier la question du renforcement de l’histoire au secondaire (2014). Ces rapports ont en commun d’avoir proposé des recommandations curriculaires en matière d’enseignement de l’histoire. Notre objectif a consisté à identifier des orientations convergentes et divergentes à travers ces trois rapports. Les résultats indiquent, d’une part, la présence d’un discours commun, en faveur d’une réforme curriculaire. D’autre part, ces résultats révèlent de fortes spécificités, notamment au regard du rapport du Comité d’experts chargé d’étudier la question du renforcement de l’histoire au secondaire (2014) militant pour une approche nationaliste.
Comment les recherches en didactique de l’histoire construisent-elles l’élève ?
Authors: Tutiaux Guillon Nicole
Published: March 2020

En didactique de l’histoire, le processus de construction de l’élève reste implicite. Cet article en vise une explicitation et une réflexion sur les catégorisations à l’oeuvre à partir d’une analyse textuelle de 89 publications (1991-2018). Sur le modèle de la contribution de Daunay et Fluckiger (2011), les discours ont été classés selon trois catégories : sujet scolaire, sujet épistémique, sujet social, complétées de celle du sujet politique. Dans le corpus analysé apparait nettement la dominante du sujet épistémique, construit plus ou moins en contraste avec le sujet scolaire, en connexion au sujet politique et influençant la façon dont est envisagé le sujet social. Rien d’étonnant à cela pour des recherches en didactique, centrées sur la discipline, mais cette construction se fait aux dépens de certains questionnements, mentionnés dans le fil de cet article.
Usages et représentations des tablettes dans les foyers et à l’école : quelle continuité?
Authors: Azaoui Brahim , Combe Christelle , Cappellini Marco
Published: March 2020

Dans notre étude, nous nous intéressons aux représentations et aux usages rapportés des tablettes numériques dans les sphères privées et pédagogiques de la part de trois groupes d’acteurs d’un collège français : les parents d’élèves, les élèves/enfants et les enseignants de langues. Dans une approche systémique, que nous comparons à l’approche sociocritique, nous analysons ces représentations et ces usages et cherchons à comprendre quelles dynamiques traversent les deux sphères afin de comprendre quelles sont les continuités et les discontinuités de la perception des groupes d’acteurs. Nos analyses montrent entre autres des continuités concernant la perception de l’intégration des tablettes comme facteur de motivation ou encore des questionnements quant à la formation nécessaire pour une utilisation efficace de ces outils. Nous discutons ces résultats et développons des réflexions des continuités et discontinuités observées.
Les contaminations urbaines de Jeanne Simone
Authors: de Morant Alix
Published: March 2020

Conçues pour l’espace urbain, les pièces de la chorégraphe Laure Terrier combinent les qualités spatiales du lieu et les tonalités du milieu dans lequel elles s’inscrivent avec celles d’un travail corporel fondé tant sur les protocoles du Contact Improvisation et sur les pratiques somatiques du Body-Mind Centering que sur une réappropriation de gestes ordinaires. L’analyse de sa dernière création, Nous sommes, présentée au festival Mimos en 2015, repose sur la reprise qui en a été faite en septembre de la même année dans le contexte métissé de la place Arnaud-Bernard à Toulouse. Dans cette pièce, un imaginaire somatique comme une gestuelle dérivée du quotidien concourent à rétablir un moment d’harmonie sociale.
Les archives de la communauté sourde à Paris, quelles possibilités d’un regard élargi ?
Authors: Cantin Yann
Published: March 2020

Depuis une quarantaine d’années, les recherches en histoire de la communauté sourde française s’appuient principalement sur la richesse de trois siècles de sources archivistiques conservées à l’Institut National des Jeunes Sourds (INJS) à Paris. Cependant, les recherches récentes s’intéressant de plus en plus à l’histoire sociale et l’histoire associative sourde, ces archives commencent à montrer leurs limites. L’apport des nouvelles technologies, que ce soient par la numérisation des sources, la reconnaissance des textes, l’usage de la généalogie, et de nouvelles sources d’archives apportent une vision renouvelée de l’histoire sourde française par une compréhension plus nuancée de ses interactions avec la société française.

On the integration of methodological principles of vocal schools in the practice of foreign vocal art teachers within the system of China’s higher music education
Authors: Shalaeva Anna
Published: March 2020

The goal of this article consists in determination of the relevant problems in preparation of students majoring academic solo singing in the Institute of Art of Jinggangshan University in groups of the educators representing vocal schools of Russia. The article examines the key aspects of the problems of Chinese vocal education in the context of European representation on the fundamentals of vocal skills. The study is dedicated to comparison of academic programs in the two leading universities of Russia and China, as well as detailed analysis of the curricula. The curriculum of Herzen State Pedagogical University of Russia focuses on the development of general cultural and professional vocal cycle, while Jinggangshan University focuses on upbringing an ideologically faithful citizen of the People’s Republic of China. The conclusion is made that despite the major impact of PRC’s leader Mao Zedong upon the music and vocal education, as well as vocal-methodological conference held in Beijing in 1957, the development of the vocal-pedagogical process has stagnated. The educators and students of music education in PRC should pursue the following objectives: openness to the new as a condition for cultural development; balance between the national spiritual values and professional competences; fulfillment of the role of cultural dialogue as a way of existence of art in the modern Communist China; preservation and continuous improvement of the system of music and arts education.
To the question of studying the American mass media discourse on immigration
Authors: Kirichenko Natalia Rostislavovna
Published: March 2020

This article is dedicated to the analysis of discourse of the modern American mass media communication space dedicated to the subject field of immigration. The work describes the existing attitudes of mass media and population to the problem of immigration and immigrants, characterized by contradiction and polarization, as well as demonstrates various processes of stereotypization of perceptions on the migration discourse. The subject of this research is the current American mass media discourse on the topic of immigration. The main goal lies in determination of attitudes developed by the American mass media and society on the immigrants, which concepts are used for their description, and how it affects the social perception of such complex phenomenon as immigration. The article is structures on the basis of text interpretation of factual material, with application of two methods of discursive analysis: analysis of lexical means for determining explicit representations; and analysis of grammar structures for determining implicit meanings. The research displays that mass media accommodate different points of view, and at the present moment, the public space of American mass media indicates different types of discourse revealing polar understanding of immigration, The President of the country is one of those, who vividly expresses negative attitude to the problem of immigration and immigrants. On the other hand, the neoliberal discourse seems more neutral and even compassionate. Therefore, the trend of describing immigrants in negative connotations is reducing. Despite the attempts of country’s leadership to create a negative image of an immigrant, the analysis of contradictory attitude to them proves that the role of mass media in formation of public opinion is not as significant.

Authors: Gurin Vladimir , Obletsova Elena
Published: March 2020

The subject of this research is the proverbs and sayings with lexical components “truth” and “lie” in the English language. The relevance of their studying is substantiated by the need in theoretical conceptualization and practical implementation of these phraseological units in aspect of the problem of interrelation between cultural and language, which contributes to more profound understanding of national mentality reflected in the English linguistic worldview. The article explores and analyzes the phenomena of proverbs and sayings, determines their common and differentiating traits. Using the method of semantic analysis, the author develops the classification of proverbs and sayings with lexical components “truth” and “lie”, as well as describes theory structure. As a result of the conducted research, the author determined 31 proverbs and sayings. They reveal the multifaceted nature of human existence, elucidate the perception of truth and lie in the English-language world. Truth and lie are associated with the means of achieving something. At the same time, truth does not always has a positive connotation, but serve as a tool for causing harm to others. Lie is the reason of negative, undesired events.
The problematic of translation of legal texts
Authors: Kurchinskaya-Grasso Natalia
Published: March 2020

This article explores the translation of legal texts, as it is usually fraught with a variety of challenges of linguistic and extralinguistic nature. The translator must have a strong command of linguistics, translation skills and profound knowledge of national and international criminal-procedural of civil-procedural law.  Focus is made on the one hand on determination of typology of general linguistic and translation problems pertaining to legal documents, and on the other – on identification of peculiarities of these problems depending on qualification of a specialist doing legal translation. The main characteristics of legal texts are viewed from the perspective of applied comparative legal science. Interdisciplinary approach towards research in the area of legal translation is a logical solution for the analysis of emerging problems. The article demonstrates some mistakes in translation of legal terms on the example of English, Polish, and Italian languages. The author comes to the conclusion that for a translator without the background of legal practice it is difficult to do the translation of legal texts; as well as submits a proposal on comprising methodological recommendations.

The work is conducted within the framework of semantic syntax and logics of language. The main conclusion consists in determination of the primary role of the modus of necessity in the texts with causal semantics, as well as potential of a modus to form the semantics of cause and effect in the texts. The relevance of this article us substantiated by reference to such modern linguistic directions as the logics of language, semantic syntax, and syntax of text.
Structural-semantic peculiarities of the concept of “fear” in text of V. P. Astafyev’s military novel “Cursed and Killed”
Authors: Matantseva Marina Borisovna
Published: March 2020

This article is dedicated to structural-semantic analysis of the emotional concept of “fear”. Emotional concept is a complex structural cognitive-mental formation that reflects mental experiences of a person; usually verbalizes, cultural and ethnically substantiated. Fear is a negative basic emotion initiating unpleasant feelings that emerge assessing the situation dangerous or harmful, or in mobilization of all resources for confronting the threatening circumstances. The goal of this work consists in identification of structural-semantic peculiarities of the emotional concept of fear in the text of a military novel by the means of analysis of its semantic, imagery and value components. The military novel “Cursed and Killed” by the Siberian writer V. B. Astafyev served as the foundation for this study. Research results consist in determination of the individual-authorial attributes of semantic component of the concept of “fear; analysis of the original conceptual metaphors and metonymies comprising the content of imagery component of the concept of “fear”; description of most typical associative-imagery metaphors and active metonymic models; revelation of the content of value component. Special attention is given to linguocognitive interpretation of the emotional concept of “fear” as a mental multidimensional formation serving as the means for perception of war.
“Insignificant” characters: on the one peculiarity of Russian epic concept of heroism
Authors: Mironov Arsenii
Published: March 2020

  The subject of this research is the concept of heroism (bogatyrs) as an element of Russian epic mentality. The focus of attention is the peculiarities of epic understanding of bogatyr power that excludes the interpretation by an epic bard of “his” character as a giant. Meanwhile, the popular in science representation of particular characters of the Russian Epos (Svyatogor, Mikula Selyaninovich, Ilya Muromets) as giants is caused by their idealization, convergence of an epic with a tale or myth, as well as readiness to proliferate upon epics such laws of poetics that are considered universal from the perspective of ethnographic theory and strive of the scholars of mythological school to distinguish in epic heroes the characters of the ancient religious systems. Based on the analysis of epic records, the author demonstrates that the bogatyrs are not giant, but rather look as regular people. Special attention is given to the adjustment of a receptive stereotype, associated with perception of the epic image of Svyatogor, caused by a distorted interpretation of this image by illustrators of the epics in the XIX century.  
El kitsch en los monumentos de Semana Santa en Colombia
Authors: Usme Zuly
Published: March 2020

Se analizaron 27 monumentos eucarísticos del Jueves Santo en iglesias colombianas desde 2004 a 2017 cada dos años. En estas construcciones se identificó la expresión de la estética kitsch por medio de un análisis iconográfico de las estructuras simbólicas ancladas a las superficies visuales de los objetos que se presentan en los monumentos y de los materiales usados en su construcción. El kitsch religioso no tiene el propósito de suscitar ref lexión intelectual en el público, más bien su fi n es emocional, apela al poder y al fervor de la tradición religiosa que, en el marco del Jueves Santo, lo envuelve todo. El kitsch religioso no tiene propósitos intelectuales, los objetos están ahí y su presencia es suficiente, es por esto que los monumentos del Jueves Santo son apreciados por los sentimientos profundos de devoción que generan en los asistentes. Los monumentos eucarísticos apartan de la realidad tanto al creyente cotidiano como al practicante eventual y remontan a los episodios que se narran a través de su carácter palimpsestual y la metonimia emocional y efímera.

The ABC method as a tool for blended learning course development at Bergen University Library
Authors: Steiner Pål , Rødland Ingunn , Langseth Henry , Hansen Christian Højberg
Published: March 2020

Embarking on planning and design of new library courses, or just even redesigning them, might be challenging in an everyday busy schedule. Especially if you want to try out new digital applications or features that could give the training an edge towards students, often prejudiced to what they can expect from a traditional library course. Ideally you engage colleagues and even students and faculty members in such a process. But how can you allocate enough time and resources to reach such ambitions?

The ABC method, developed at University College London, is an effective, engaging and creative approach. In only 90 minutes groups are able to work together hands-on to create a visual storyboard outlining the type and sequence of learning activities aligned with the course’s learning outcomes. Blended learning and co-creation are often encouraged in course design in many educational institutions these days. The ABC method encourage also library instructors to think about e-learning tools, methods for active learning and opportunities for co-creation.

Library courses, in difference from regular courses at universities, if often taught as a “one-shot-session”, and they rarely include formal evaluations. We therefore felt the need to adapt the method to better suit these circumstances. We adjusted both agenda and material, but all ideas and principles follow the original method. Evaluation showed good feedback regarding the proportion of participants who intended to change their course design after attending the workshop.

This session will present the basic principles of the ABC-method and our experiences working with this approach to blended course planning.

(Alternative if workshop: This workshop will give let you plan and design elements of a given course, utilizing the tools and methods of the ABC method.)
"Into the great wide open"
Authors: Miettinen Mervi
Published: March 2020

Open science and research is no longer relevant just for people pursuing an academic career. Instead, it is something that all students entering the university should be increasingly familiar with as they proceed with their studies. Tampere University Library has actively integrated open science into its information literacy teaching, beginning from the first-year orientation studies and continuing throughthe Bachelor’s and Master’s thesis seminars. Following the guidelines provided by the idea of cumulative learning (Maton 2009), the IL teaching at Tampere University Library aims at connecting new knowledge with existing knowledge, effectively building on the students’ previous IL studies throughout their degree.

In addition, the ACRL Framework for Information Literacy (2015) acts as a roadmap for developing IL teaching at Tampere University Library: the Library’s entire teaching team has gathered in workshops and together produced a view of the frames that best suits the University’s students. The frames are awork-in-progress, and the teaching team will continue to work on better adapting the frames. One of the results is the way in which the frames and the threshold concepts within determine the depth inwhich issues such as open science and research are taught at different levels (cf. Sipilä, Miettinen &Tevaniemi, 2019). In order to ensure student engagement, concepts like open science are presented at each level in a way that is relevant to the students’ current studies, beginning with the concept itself and later advancing towards viewing the students as both users and creators of open science.

This presentation will highlight some of the current ways in which open science and research is integrated into the information literacy curriculum at Tampere University Library, and how the ACRL framework can act as a way for library teaching staff to comprehend and develop IL teaching in highereducation.
Educating PhD students for knowledge-driven society
Authors: Renn Oliver , Dolenc Jozica , Betschart Leo , Schnabl Joachim
Published: March 2020

Universities educate students for working in knowledge-driven societies. Whereas subject-related knowledge is part of every curriculum, institutions of higher education fail to teach systematically how to utilize and benefit from today’s variety of digital tools. Students and researchers are mostly unaware of what they lack to work more effectively and efficiently and to benefit from existing knowledge. Since this lack of awareness is not obvious to students and researchers (unknown unknowns; you cannot miss something that you do not know), it is difficult to convince them that there is a gap that needs to be filled. 

In 2014, we decided to tackle this problem by creating and developing the course “Scientific Information Retrieval & Management in Life Sciences and Chemistry”. The unique 2 ECTS course features a multi-level approach to obtain and employ scientific information and to get students information savvy. On one hand, the course demonstrates the bigger picture: We discuss the aspects of scientific writing and publishing, critical choice of data sources, patents, visualisation and design, text mining and data pipelining, knowledge generation, outreach and impact of publications. On the other hand, we highlight an extensive list of field-proven tools that can assist researchers in their daily activities. 

We also wanted to foster a lasting impact on how students utilize databases, tools, software, and web services. Thus, at the end of the course students have to write an essay describing their current information workflow or their (un)met information needs. These essays confirm and explain how the students changed their information use, and which parts of the course they may have not understood. Moreover, essays that describe unmet information needs allow us to explore possible solutions and to work with our vendors. In our talk, we will share the concept for the course and report on our experiences.
Library-faculty collaboration in the development of an accredited phd course in transferable academic skills
Authors: Sundstøl Shea Allison , Nordsteien Anita
Published: March 2020

Background: The PhD course Literature Management and Scientific Communication was establishedin 2019 through a library-faculty collaboration. This is the first accredited generic PhD course at this university, and it provides 5 ECTS credits. In the first course, there werep articipants from four of our eight PhD programs, researching topics spanning from religion to robotics. Our main idea was that bringing PhD candidates from different programs together for such a course may add extra value in the form of enhancing communication and understanding across the disciplines.

Methods: The study has a mixed methods design. A preliminary survey was conducted in 2017 to revealthe PhD candidates’ information needs, which provided a basis for planning the course content. To examine the candidates’ learning outcomes and further improvements for future courses, NVivo was used to analyse observations that were recorded during the course, in addition to the participants’ course essays and evaluation forms.

Results: The 2017 survey had a response rate of 43% (n = 91). More than 50% of the respondents expressed a need for library courses in literature searching, systematic reviews, research data management and the publishing process. The PhD course was designed based on these findings, and we overbooked the course having accepted 20 participants, including 5 international candidates. The main finding was that several of the participants found the course surprisingly useful to their research and to their career plans. However, there were widely varying opinions about including such a diverse group.

Discussion: Having a generic course for early-stage researchers from such a diversity of fields was challenging, and the article discusses several issues to consider for future courses. Most importantly, the prior knowledge was vastly different among the participants. This emphasizes the need for increased library-faculty collaboration to reach out to all PhD candidates in an early stage.
Prognostic analysis of histopathological images using pre-trained convolutional neural networks: application to hepatocellular carcinoma
Authors: Lu Liangqun , Daigle Bernie J.
Published: March 2020

Histopathological images contain rich phenotypic descriptions of the molecular processes underlying disease progression. Convolutional neural networks, state-of-the-art image analysis techniques in computer vision, automatically learn representative features from such images which can be useful for disease diagnosis, prognosis, and subtyping. Hepatocellular carcinoma (HCC) is the sixth most common type of primary liver malignancy. Despite the high mortality rate of HCC, little previous work has made use of CNN models to explore the use of histopathological images for prognosis and clinical survival prediction of HCC. We applied three pre-trained CNN models—VGG 16, Inception V3 and ResNet 50—to extract features from HCC histopathological images. Sample visualization and classification analyses based on these features showed a very clear separation between cancer and normal samples. In a univariate Cox regression analysis, 21.4% and 16% of image features on average were significantly associated with overall survival (OS) and disease-free survival (DFS), respectively. We also observed significant correlations between these features and integrated biological pathways derived from gene expression and copy number variation. Using an elastic net regularized Cox Proportional Hazards model of OS constructed from Inception image features, we obtained a concordance index (C-index) of 0.789 and a significant log-rank test (p= 7.6E−18). We also performed unsupervised classification to identify HCC subgroups from image features. The optimal two subgroups discovered using Inception model image features showed significant differences in both overall (C-index = 0.628 andp= 7.39E−07) and DFS (C-index = 0.558 andp= 0.012). Our work demonstrates the utility of extracting image features using pre-trained models by using them to build accurate prognostic models of HCC as well as highlight significant correlations between these features, clinical survival, and relevant biological pathways. Image features extracted from HCC histopathological images using the pre-trained CNN models VGG 16, Inception V3 and ResNet 50 can accurately distinguish normal and cancer samples. Furthermore, these image features are significantly correlated with survival and relevant biological pathways.
Impact of the antidepressant citalopram on the behaviour of two different life stages of brown trout
Authors: Ziegler Michael , Knoll Sarah , Köhler Heinz-R. , Tisler Selina , Huhn Carolin , Zwiener Christian , Triebskorn Rita
Published: March 2020

Background

Over the last two decades, there has been a constant increase in prescription rates of antidepressants. In parallel, neuroactive pharmaceuticals are making their way into aquatic environments at increasing concentrations. Among the antidepressants detected in the environment citalopram, a selective serotonin reuptake inhibitor, is one of the most commonly found. Given citalopram is specifically designed to alter mood and behaviour in humans, there is growing concern it can adversely affect the behaviour on non-target wildlife

In our study, brown trout were exposed to citalopram (nominal concentrations: 1, 10, 100, 1000 µg/L) in two different life stages. Larvae were exposed at 7 and 11 °C from the eyed ova stage until 8 weeks post yolk sac consumption, and juvenile brown trout were exposed for 4 weeks at 7 °C. At both stages we measured mortality, weight, length, tissue citalopram concentration, behaviour during exposure and behaviour in a stressfull environment. For brown trout larvae additionally hatching rate and heart rate, and for juvenile brown trout the tissue cortisol concentration were assessed.

Results

During the exposure, both larvae and juvenile fish exposed to the highest test concentration of citalopram (1 mg/L) had higher swimming activity and spent longer in the upper part of the aquaria compared to control fish, which is an indicator for decreased anxiety. Most probably due to the higher swimming activity during the exposure, the juveniles and larvae exposed to 1 mg/L citalopram showed decreased weight and length. Additionally, in a stressful artificial swimming measurement device, brown trout larvae displayed the anxiolytic effect of the antidepressant by reduced swimming activity during this stress situation, already at concentrations of 100 µg/L citalopram. Chemical analysis of the tissue revealed rising citalopram tissue concentrations with rising exposure concentrations. Tissue concentrations were 10 times higher in juvenile fish compared to brown trout larvae. Fish plasma concentrations were calculated, which exceeded human therapeutic levels for the highest exposure concentration, matching the behavioural results. Developmental parameters like hatching rate and heart rate, as well as mortality and tissue cortisol content were unaffected by the antidepressant. Overall, we could trace the pharmacological mode of action of the antidepressant citalopram in the non-target organism brown trout in two different life stages.

Hospital diet is an essential part of modern therapy in all medical departments. It comprises both the so-called normal diets which are prepared according to modern nutrition knowledge, dietetic foods and the various forms of artificial nutrition. The dietary department provides food and nutrition services that consistently promote adequate nutritional intake, improve health and enhance the quality of life. This study was cross-sectional from January 2016 to December 2016. The nonprobability purposive sampling method was used for data collection. Total 164 samples were collected purposively within the data collection period. There were 150 hospital patients and 14 dietary staff who collected the data secondary level hospitals by using semi-structured questionnaire. The data was analyzed by using SPSS. Among 150 patients 92% of the patients ate hospital diet and only 8% of the patients did not eat hospital diet. Among them 6.7 % of the patients said that the hospital supply foods were unhygienic and 93.3% say the hospital food was healthily. There was 8% patients complains that the supply food was not neat and 13% of the patient says that they did not use the spoon. There were 64.3% of the dietary staff did not use non touch technique during food distribution. Majority of the patients 79.3% said they have no training about food hygiene. The satisfaction level of the dietary staff, there was 57.1% staff were satisfied and there was 21.4% dietary staff were very satisfied following 21.4% was dissatisfied. The satisfaction among the patient 75.8% patient was satisfied 9.8% of the patient were dissatisfied. Dietary department improved the food quality and supplied adequate quantity of food among the patients. Dietary department needs to clean regularly and training should be implemented among the nutrition personnel. The sufficient lighting facility may improve for the patient’s satisfaction.
Recommending Curated Content Using Implicit Feedback

Matrix factorization (MF) which is a Collaborative filtering (CF) based model, is widely used in the recommendation systems (RS). For our experiment, we collected data from a company's internal web site where curated contents are published and pushed to the employees. However, the size of the dataset is small and interaction data is also limited. We got a sparse matrix when we generated a user-item rating matrix. We have used Multi-Layer Perceptron (MLP) to calculate the rating scores from the implicit feedbacks. However, on this sparse dataset traditional content only or CF-only RSs do not work well. Here, we propose ahybrid RS that incorporates content similarity scores into an MLP-based MF-model. To integrate the content similarity scores into the MF, we have defined an objective function based on a regularization term. The experimental result shows that our proposed model demonstrates a better result than the traditional MF-based models.

The study was carried out to determine marketing margins in the marketing of garri in Cross River Central Agricultural Zone, Nigeria. The study employed primary data which were obtained directly from garri marketers and analyzed with the use of descriptive statistics and marketing efficiency model. A three-stage (multi-stage) sampling technique was used in the selection of respondents and using 10% proportionality a sample size of 196 respondents was obtained from the sample frame of 1960. Analysis of the result showed that garri marketing in the area is greatly influenced by the socio-economic characteristics of garri marketers. Furthermore, the result indicated that marketers in Ofodua and Ochon markets recorded the lowest margin of ₦200 per bag of garri. This is against the ₦300 margin recorded by marketers in Apiapum, Okuni, Nko and Akparabong markets, ₦400 for markets in Ugep and Ikom Urban and ₦600 for the market in Agoi, respectively. The average marketing margin for garri in the markets was ₦378. Producers of garri sell it to the wholesalers in bulk sometimes through intermediaries like the village agents or directly to them. Retailers obtain the product from wholesalers and retail directly to final consumers also sometimes passing through movement agents and cooperative consumer outlets before reaching the final consumer. The mean marketing efficiency for garri across the study area is 0.78. This is slightly lower than the average efficiency level for Ugep, Apiapum and Ikom urban markets (0.90, 0.8. and 0.90, respectively). The following were recommended: trading activities and attributes of garri traders should be regulated by governments to ensure efficiency in the business, government, corporate bodies and NGO’s should assist in the rehabilitation of feeder roads to guarantee easy movement of garri from the producers to the consumers and traders in garri should be provided with training by government to increase their efficiency in the distribution of garri.
Low-cycle Fatigue Behavior and Constitutive Relations for a Ferritic Stainless Steel at Elevated Temperatures
Authors: Kabir S. M. Humayun , Yeo Tae-In
Published: March 2020

In this paper, the tensile and strain-controlled cyclic deformation behavior of a ferritic stainless steel which is developed for the exhaust manifold of automobiles is evaluated experimentally at different temperatures. The effect of temperature on monotonic tensile responses such as yield strength and ultimate tensile strength and the effect of temperature and strain amplitude on the evolution of peak stress are assessed. The objective of this study is also to reveal the mixed mode of cyclic hardening–softening behavior of the ferritic stainless steel under strain-controlled fatigue test conditions. A parameter, critical accumulated plastic strain, is introduced to the constitutive equations for the material for describing the hardening - softening responses. The nonlinear constitutive equations for describing the cyclic responses are implemented into Finite Element code using determined parameters for obtaining numerical simulation. The stabilized hysteretic responses obtained from experiment and predicted from numerical simulation are compared and found to be realistic.

Aim: The aim this research work is to formulate and characterize Poly Sulfoxyamine Grafted Chitosan Coated contact Lens.

Methodology: Poly Sulfoxyamine Grafted Chitosan was used for coating the Lens & converting it in to Antimicrobial Lenses. Poly Sulfoxyamine Grafted Chitosan was performed in the presence of pyridine and further treatment with ammonia during reaction of Thionyl chloride & chitosan. The UV light interference, visible light transmission and antimicrobial evaluation were studied.

Results: The results indicate that Contact lenses prepared with Modified Poly Sulfoxyamine Grafted Chitosan absorbed some UV radiation & does not interfere with visible region. Due to the antimicrobial activity of modified Chitosan, the growth and transmission of micro organisms are reduces in coated Lens as compared to uncoated Lens.

Conclusion: On basis of the results we concluded that Modified Poly Sulfoxyamine Grafted Chitosan might be used as coating material or material for making contact Lenses which will be less susceptible for microbial contamination.
