The interest for natural dye has increased together with the concern in sustainability and environmental awareness within the textile industry. Natural dye is one of the oldest techniques when it comes to textile production, but when synthetic dyestuffs were discovered, the usage of the technique decreased. Today, the technique is slowly coming back together with the awareness in sustainability. However, regarding surface patterns, the expression is quite limited, and patterns are created by dyeing techniques, muted colors and nature as an obvious inspiration. This degree work explores natural dye print by designing a screen printed surface pattern collection, and the project advocates for and is an addition to the field of natural dye print. The methods used were drawing, digital sketching and screen printing. The methods of designing were done through practical workshops, both for sketching patterns and to explore techniques within natural dye print. The female body is a design theme in the work and the intention is simply to portray the body as it is. The motive has not been chosen to provoke, to address a political issue or to evoke discussion. The result is three surface patterns printed with different printing techniques on different fibers. A significant part of the result is the reference library containing all the printed samples and can be used for further research within the field. Choice of fabric and scale of design was done with fashion fabric in mind, however, to focus on the design and technique the designs are not presented on any kind of product. Tests were done to try out the light fastness of the different colorants on different fibers. This project has expanded the field of natural dye print by adding a screen printed surface pattern collection with thematic patterns and an expression that does not reveal the use of natural dye. The project also resulted in a steppingstone for further work within the field.

Une des caractéristiques définissant les êtres vivants est leur capacité à se reproduire. La reproduction sexuée est le mécanisme qui a encouragé la sélection positive des espèces au cours de l’évolution en augmentant leurs diversités génétiques. Lors de leurs reproductions les angiospermes (les plantes à fleurs) utilisent un organe sexuel appelé fleur. Le sexe de cet organe est déterminé par la présence ou l’absence de deux différents types de tissus reproducteurs. Le tissu reproducteur mâle est appelé étamine et porte le pollen. Le tissu reproducteur femelle est appelé pistil et est constitué d’un ou plusieurs carpelles. La labilité sexuelle et l’importance économique des Cucurbites comme Cucumis melo (le melon), Cucumis sativus (le concombre) et Citrullus lanatus (la pastèque) ont fait d’eux des organismes-modèles pour l’étude du déterminisme du sexe contrôlé par un réseau génétique. Le modèle génétique du déterminisme du sexe de Cucumis melo peut être expliqué par la modulation et l’interaction de trois gènes: CmACS-7, CmWIP1, CmACS11. Le gène CmACS-7 est situé au locus M et code une enzyme de biosynthèse de l’éthylène (Boualem et al 2008) réprimant le développement des étamines. Le gène CmWIP1 est situé au locus G et code un facteur de transcription potentiel réprimant le développement du carpelle (Martin and al 2010). Et le gène CmACS11 est situé au locus A et code une enzyme de biosynthèse de l’éthylène réprimant l’expression de CmWIP1 (Boualem et al 2015). Au vu de la croissance de la population mondiale, il est nécessaire d’élargir le nombre d’outils génétiques permettant l’amélioration de la sélection variétale des plantes cultivées dont font partie les Cucurbites. La plupart des plantes hybrides sont issues d’un croisement entre deux plantes différentes, une plante mâle et une plante femelle. Pour améliorer la production de ces hybrides, il est primordial de connaître le sexe des plantes parentes et particulièrement celui des lignées femelles. Dans cette optique, les sélectionneurs ont besoin d’élargir leurs panels d’allèles permettant le contrôle du développement du carpelle. L’ingénierie de ces allèles permettra de générer des plantes gynoïques portant uniquement des fleurs femelles mais aussi d’augmenter la proportion de fleurs pistillées et de contrôler le délai d’apparition des fleurs pistillées. Ces améliorations de la sélection variétale des Cucurbites pourraient générer des alternatives aux mécanismes de stérilité mâle, de castration manuelle ou chimique. Ainsi qu’une meilleure maîtrise de l’apparition de l’effet nid, générant des plantes potentiellement plus compactes et plus rapidement productives. La manipulation des mécanismes, régulés par CmWIP1 et contrôlant le développement du pistil, pourrait permettre d’identifier de nouveaux allèles impliqués dans le développement du carpelle. Mes travaux de recherche se sont appuyés sur la mise en œuvre d’un crible génétique afin d’identifier les membres du réseau génétique auquel appartient CmWIP1, l’unique gène identifié à ce jour contrôlant le développement du carpelle chez C. melo. Ma thèse a eu pour but d’identifier des gènes suppresseurs de la fonction de TT1 (AtWIP1) et de NTT (AtWIP2), deux membres de la famille WIP chez Arabidopsis thaliana. Ces mutations suppresseurs pourront supprimer les phénotypes d’arrêt de croissance et de sénescence induits par la surexpression de TT1 ou de NTT. Pour cela, j’ai généré une population de lignées d’Arabidopsis thaliana surexprimant de manière inductible les séquences codantes de TT1 ou NTT et ayant subi une mutagenèse à l’EMS. J’ai ensuite criblé cette population pour identifier les plantes suppresseurs et les mutations causales. Mon projet de recherche a permis d’identifier quatre locus potentiellement impliqués dans le contrôle du développement du carpelle. La caractérisation de ces locus pourra aboutir à un meilleur contrôle du déterminisme du sexe des Cucurbites et des plantes possédant un mécanisme similaire. / One of the characteristics of living organisms is the ability to reproduce themselves. Sexual reproduction is a mechanism that increases the potential diversity of species and their positive selection. To reproduce most of plants species use a type of sexual organ named flower. The sex of this organ is determined by the presence or absence of two different types of reproductive tissue. The stamen is the male reproductive tissue and the carpel is (the female reproductive tissue). In many species the development of these tissues is controlled by a network of genes. Cucumis melo (melon) is a model plant to study genetic network controlling sex determination. Melon sex determination genetic model can be explained by the modulation of three genes. The gene CmACS-7 at the locus M which encodes for an ethylene biosynthesis enzyme that represses stamen development (Boualem and al 2008). The gene CmWIP1 at the locus G which encodes a putative transcription factor that represses carpel development (Martin and al 2010). And the gene CmACS11 at the locus A which encode for an ethylene biosynthesis enzyme that represses CmWIP1 expression (boualem et al 2015). The aim of this thesis project is to understand in which biological process cmWIP1 is involved to inhibit carpel development. The identification of the precise function of cmWIP1 will lead to the identification of new putative alleles controlling carpel development and sex determination. To achieve this goal we set up a genetic screen in Arabidopsis thaliana to unravel genetic interactors of CmWIP1. At the present moment we found four putative genetic interactors. These putative candidates will be tested in melon. Plants that are mutated in theses cmWIP1 genetic interactors should harbour female organ inside each of their flowers. Then the introgression of these alleles in crop species may increase fruit and/or seed yields.

Background: Children's screen usage has increased in recent years and parents' screen usage has strong association with children's screen usage. When the specialist nurse works based on family-centered nursing, conversations about screen usage can include the whole family. Purpose: To describe specialist nurses' experiences of working with children’s screen usage in Child Health Services.  Method: The study was conducted with qualitative design with inductive approach. Totally 11 specialist nurses in Child Health Services were interviewed. Qualitative content analysis according to Graneheim and Lundman (2004) was used to analyze that data material. Results: The analysis of the interview material collected led to two categories, dialogue and reflection and the challenges of screen usage.  Within these categories seven subcategories were identified. There was an opportunity to talk about children's screen usage in parental groups and health visits. Specialist nurses described that there were challenges depending on the parents' approaches to screen usage and that the screen competed with children's other activities. Conclusion: This study showed the importance of specialist nurses in child health services bringing up the topic of screen through dialogue and reflection with children and parents. Screen usage was described as a difficult subject and there were challenges in the work. / Bakgrund: Barns skärmanvändning har ökat de senaste åren och föräldrars skärmanvändning har starkt samband med barns skärmanvändning.

Syfte: Att beskriva specialistsjuksköterskors erfarenheter av att arbeta med barns skärmanvändning inom barnhälsovården. Metod: Studien genomfördes med kvalitativ design med induktiv ansats. Totalt intervjuades 11 specialistsjuksköterskor inom barnhälsovården. Kvalitativ innehållsanalys enligt Graneheim och Lundman (2004) användes för att analysera datamaterialet. Resultat: Analysen av det insamlade intervjumaterialet ledde fram till två kategorier, dialog och reflektion samt skärmanvändningens utmaningar. Inom dessa kategorier identifierades sju subkategorier. Det fanns möjlighet att samtala om barns skärmanvändning i föräldragrupper och vid hälsobesök. Specialistsjuksköterskor beskrev att det fanns utmaningar beroende på föräldrars inställningar till skärmanvändning samt att skärmen konkurrerade med barns andra aktiviteter. Slutsats: Denna studie visade vikten av att specialistsjuksköterskor inom barnhälsovården tar upp ämnet skärmanvändning genom dialog och reflektion med barn och föräldrar. Skärmanvändning beskrevs som ett svårt ämne och att det fanns utmaningar i arbetet.

L’écran est une interface omniprésente utilisée quotidiennement. Sur-sollicité par les écrans, l’individu ne peut pas percevoir l’intégralité des informations. La compréhension de l’attention portée aux contenus médiatisés est un enjeu crucial dans la stratégie marketing. Un paramètre n’a pas été pris en compte dans les précédentes études: la qualité technique de l’image médiatisée. Elle peut être définie comme l’ensemble des paramètres suivants : la définition, la fréquence image, la luminosité et la couleur. Pour mesurer la perception de l’amélioration de ces paramètres, une phase exploratoire a été menée comprenant un test de qualité perçue, un focus group et des entretiens. Une phase empirique confirmatoire a suivi pour étudier l’attention visuelle et la mémorisation de l’information médiatisée grâce à deux expérimentations. Une série d’entretien et un focus group ont permis d’étudier l’hyperréalité dans l’image médiatisée et son impact sur l’immersion et la qualité d’expérience. / The screen is a ubiquitous interface daily used. Overextended by screens, the individual cannot perceive all the information. Understanding the visual attention to media content is a crucial issue in the marketing strategy. A parameter of the mediated image has not been taken into account in the studies conducted so far: the technical quality of the image. It can be defined as the set of parameters that objectively compose an image: the definition, the image frequency, the brightness dynamics and the color. To measure the perception of the improvement of these parameters, an exploratory phase was conducted including a perceived quality test, a focus group and interviews. A confirmatory empirical phase followed to study the visual attention and memorization of mediated information through two experiments. A series of interviews and a focus group explored hyperreality in the mediated image and its impact on immersion and quality of experience.
