In an organization such as a university with many institutions and new employees the onboarding process is a key activity for the employee life cycle. This study examines the possibilities and limitations of further digitalization of the process by including new formats for information.  The format in question is 360-videos. These videos can be viewed both on head mounted displays which are used to create a 3D environment but also on computer screens which allows the content to be accessible to those that lack the 3D equipment. Based on semi-structured interviews with HR-employees at the university the study has found there to be many activities that are suitable for the format but also a few limitations concerning planning for and executing the development of new content for the onboarding process. The conclusions drawn from the results in this study and previous studies on the topic shows that implementation of 360-videos would lead to standardized content concerning many of the activities that cannot be done digitally by conference calls or two-dimensional videos. These activities are today done in person and at the responsibility of the new hires closest manager which leads to the activities being time consuming and can vary in terms of content.

Die Arbeit befasst sich mit der Thematik der Gesundheitsförderung für Migranten, wobei der Fokus aus einer sozialpädagogischen Perspektive heraus auf die Migrantengruppen gelegt wird, die aufgrund ihres spezifischen Migrationserlebens zum Teil in extremen Ausmaßen besonderen Stressfaktoren ausgesetzt sind, die wiederum das Auftreten von Krankheiten begünstigen oder gar hervorrufen können.Durch eine interkulturelle Öffnung der bestehenden Regeldienste sollen Migranten zukünftig die bestehenden Angebote der Gesundheitsversorgung besser in Anspruch nehmen können. Eine interkulturelle Öffnung der Regeldienste soll die besondere Erwartungshaltung der Migranten ebenso reflektieren, wie sie kulturspezifische Unterschiede aufnimmt und Sprachbarrieren abbaut.

Den zentralen Auslöser für die Forschungsarbeit stellte die spürbare Veränderung der Versorgungsstruktur im österreichischen Gesundheitswesen dar. Kritisch ist in diesem Zusammenhang die Tatsache zu sehen, dass viel weniger der Gesundheitsmarkt selbst bzw. die Kunden (Patienten) des Quasimarktes Gesundheitswesen die zu untersuchenden Veränderungen gefordert haben, sonder es sich dabei um gesundheitspolitisch induzierte Maßnahmen handelte. Deshalb wurde der kritische Blick auf die Auslöser für die Veränderung, die Implementierung der neuen Versorgungsform sowie die gesellschaftliche Betroffenheiten und Auswirkungen gerichtet. Als konkretes Beispiel wird die Reorganisation einer vollstationären Augenabteilung in eine Tagesklinik an einem österreichischen Krankenhaus untersucht.Wesentliches Ergebnis war, dass sich 8 von 10 Betroffene im Rahmen einer qualitativen Befragung für die tagesklinische Behandlung aussprechen wenn sie nach Erleben beider Versorgungsformen die Wahl hätten.Darüber hinaus konnte belegt werden, dass triviale Indikatoren wie Alter und Enfernung zwischen Wohn- und Behandlungsort viel zu kurz greifen.

Cette thèse ambitionne de contribuer à la compréhension de l’accès aux soins des bamakois selon leur statut migratoire. En effet, malgré la part importante de la population de Bamako d’origine migrante, nous avons très peu de connaissances sur leur accès aux soins. A partir des données récoltées sur le terrain et auprès des institutions maliennes et en nous basant sur des outils et des méthodes géographiques et géomatiques, nous avons pu analyser l’accès aux soins des bamakois selon leur statut migratoire.S’il est incontestable que les services de santé et en particulier ceux de base sont abondants et bien répartis à Bamako, il faut noter qu’ils souffrent de plusieurs problèmes comme la question de disponibilité permanente de personnel qualifié, la qualité des services et les dysfonctionnements entre structures de santé. Malgré l’abondance de l’offre de soins à Bamako, le taux de recours y reste trop faible. Cela confirme encore que l’accès aux soins ne se limite pas à la disponibilité physique des structures de santé. Le renoncement aux soins s’explique par une imbrication de facteurs même si la perception de la gravité de la maladie, la position dans le ménage et la profession apparaissent plus. Si l’étude n’a pas relevé de différences notoires dans l’accès aux soins selon le statut migratoire des populations, elle a tout de même montré que les stratégies de recours et l’état de santé évoluent avec la durée de résidence à Bamako / This thesis aims to contribute to the understanding of Bamako people’s access to healthcare according to their migratory status. Indeed, despite the large share of Bamako’s populations of migrant origin, we have little knowledge of their access to health services. With geographic and geomatic tools and methods, we were able to study access to health services for native and migrant populations of Bamako. While it is undeniable that health services and especially basic services are abundant and well distributed in Bamako, it should be noted that this offer suffers from several problems such as the permanent availability of qualified personnel, the quality of services offered and the dysfunctions between health structures. Despite the abundance of healthcare in Bamako, the recourse rate remains too low. This shows that access to care is not limited to the physical availability of health facilities. The renunciation of care is explained by an interweaving of factors even if the perception of the severity of the disease, the position in the household and the profession appear more. If the study did not find notorious differences in the access to the care according to the migratory status of the population, it nevertheless showed that recourse strategies and health status change with length of residence in Bamako

This thesis explores the user experience, potential and design principles of a HUD-based user interface in combination with interactive 360-degrees videos in nursing education. A HUD-based 360-degrees video was designed around a previously recorded scenario in an emergency room and user tests were conducted on nurse educators, working nurses and a nurse student.  Data from the user tests were gathered both through observations and interviews. The results show that participants' experience was overall positive and that the technology is seen as a realistic, interesting and valuable way to educate nursing students. Although no definitive design principles could be established for interactive 360-degrees videos, the result suggests that focusing on key design principles for multimedia learning may provide a better user experience. These principles include managing extraneous, essential and generative processing. / Detta examensarbete utforskar användarupplevelsen,potentialen och begränsningarna avett HUD-baserat användargränssnitt i kombination med interaktiva 360-graders videos inom sjuksköterskeutbildning. Detta gjordes genom att designa och utveckla en HUD-baserad 360-graders video och utföra användar tester på lärare inom sjuksköterskeutbildning, arbetande sjuksköterskor och en sjuksköterskestudent. Data från användartester samlades in genom observationer samt intervjuer. Resultatet visar att deltagarnas upplevelse överlag var positiv och tekniken ses som ett intressant och fördelaktigt sätt att undervisa sjuksköterskestudenter. Resultatet tyder också på att fokus på designprinciper inom multimedielärande kan bidra med en bättre användarupplevelse.

Panoramic virtual reality is an emerging technology that has recently gained the attention of both the research community and regular consumers. It allows the users to immerse themselves in omnidirectional videos with the help of a virtual reality headset : thanks to an increasing amount of affordable head-mounted-displays, any recent smartphone can offer a decent panoramic virtual reality experience. However since omnidirectional videos are videos with a large field-of-view that covers the entire sphere around the camera, they require large resolutions and thus high bitrates. This master degree project conducted at RE’FLEKT GmbH is an exploratory work that seeks to reduce the panoramic video bitrate. Because of the nature of omnidirectional videos, the user can only see a subpart of each video frame, and thus some zones of the video can attract more attention than others. The purpose of this study is to introduce the concept of region-of-interest encoding in panoramic VR. The main contribution is a method to encode panoramic videos in an H.264 video format stream with a space-variant level of details depending on the zones that attract the most the viewers’ interest. First, the region-of-interest are detected through a head-tracking module combined with a Gaussian attention model. Then, the reference video is encoded with the open source x264 encoder, with a quantization step adjusted to the region-of-interest information. The International Telecommunications Union standard subjective tests show that this method can perform better than classic H.264 encoding only in specific cases. / Panoramisk virtuell verklighet (VR) är en kommande teknik som nyligen har mött intresse från forskarsamhället och vanliga konsumenter. Det gör det möjligt för användarna att fördjupa sig i videor upptagna från flera riktningar, med hjälp av ett VR-headset : tack vare ett växande antal billiga och huvudburna bildskärmar, erbjuder alla nya smarttelefoner en passande panoramisk VR-erfarenhet. Men på grund av den breda synvinkeln i flerriktade media behöver videor med 360 graders synfält stor upplösning och därför höga bithastigheter. Detta masterexamensarbete som utförts på RE’FLEKT GmbH är ett utforskande arbete som strävar efter att reducera panoramabildens bithastighet. I flerriktade videoklipp kan användaren bara se en del av varje bildruta, härigenom får somliga zoner mer uppmärksamhet än andra. Syftet med denna studie är att introducera begreppet region-av-intresse (ROI) kodning i panoramisk VR. Huvudbidraget är en metod för att koda panoramisk video i en H.264-ström med en varierande nivå av detaljer som beror på de zoner som får mest av tittarnas intresse. Först detekteras ROI genom en huvudspårningsmodul kombinerad med en gaussisk uppmärksamhetsmodell. Därefter kodas referensvideoen med x264-kodaren (öppen källkod) med hjälp av ROI-informationen. ITU-standardens subjektiva test visar att den här metoden kan fungera bättre än klassisk H.264-kodning i enskilda fall.

Students, especially international ones have a hard time seeking accommodation in big cities like Stockholm in Sweden at an adequate pricing. To facilitate such a search process and to create a sense of trust, tenants and landlords use video and/or voice calls for early communication with one another. However, the establishment of trust among tenants and landlords in this context is a challenging task. This study thus aims to investigate if innovative virtual reality (VR) approaches like 360° videos can be used to develop trust among tenants and landlords. This study undertakes an investigation from student perspective due to the limited timeframe. This study was carried out in collaboration with Ett tak (English: One roof) which is a startup working in the rental market in Stockholm. The tenants are the students and the landlords are senior people having spare space in their homes. A pre-study was conducted to identify the expectations of the students. A landlord was filmed for the 360° video which was developed into a Unity VR app. The results from the usability study indicate that most students felt a high degree of trust towards the landlord by using an immersive 360° VR tour. Conversely, the students showed hesitation to use the 360° VR by buying their own VR headsets unless VR becomes mainstream in the different areas of life. This study builds upon existing literature that validate the positive impact of attributes like profile photos, ratings and reviews on the trust level between the providers and the consumers in a sharing economy. / Studenter, särskilt internationella, har svårt att hitta boende i storstäder som Stockholm i Sverige till lämplig prissättning. För att underlätta en sådan sökprocess och skapa en känsla av förtroende använder hyresgäster och hyresvärdar video och / eller röstsamtal för tidig kommunikation med varandra. Upprättande av förtroende bland hyresgäster och hyresvärdar är dock en utmanande uppgift i detta sammanhang. Denna studie syftar således till att undersöka om virtuell verklighet (VR) som 360° video kan användas för att utveckla förtroende bland hyresgäster och hyresvärdar. Denna studie genomför en undersökning från ett studentperspektiv på grund av den begränsade tidsramen. Denna studie genomfördes i samverkan med Ett tak, som arbetar på hyresmarknaden i Stockholm. Hyresgästerna är studenterna och hyresvärdarna är äldre människor som har ledigt utrymme i sina hem. En förstudie genomfördes för att identifiera studenternas förväntningar. En hyresvärd filmades för en 360° video som utvecklades till en Unity VR app. Resultaten från användbarhetsstudien indikerar att de flesta studenter kände en hög grad av förtroende gentemot hyresvärden genom att använda en fördjupande 360 ° VR rundtur. Däremot visade eleverna att de inte skulle köpa egna VR-headset om VR inte blir vanligt i de olika områdena i livet. Denna studie bygger på befintlig litteratur och bekräftar den positiva effekten av attribut som profilbilder, betyg och recensioner på förtroendenivå mellan leverantörer och konsumenter i en delningsekonomi.

Microwave lenses support low-phase error, wideband, wide-angle scanning, and true-time delay (TTD) beam forming. They provide ideal performance for applications such as satellites, remote-piloted vehicles, collision-avoidance radars and ultra-wideband communications systems. The emerging printed lenses in recent years have facilitated the advancement of designing high performance but low-profile, light-weight, and small-size beam-forming networks (BFNs). The microwave lens adopts a few beam ports to illuminate the prescribed receiving ports that feed energy into radiating antennas. Multi-beam patterns can be achieved by exciting multiple beam ports at a time. The design process starts with path-length equations from a limited number of beam-port foci assumptions. This constraint does not take into account the amplitude information; however, it allows an initial lens geometry to be solved. The resulted scanning angle of microwave lens is limited by the beam port contour, as such ± 90 degrees. In this dissertation, three contributions are made from the aspects of minimized phase errors, accurate and efficient simulation algorithms, and 360-degree scanning range extension. First, a minimum-phase-error, non-focal lens design method is proposed. It does not require a specific number of foci along the beam contour; however, minimum phase errors for all beam ports are able to be achieved. The proposed method takes into account flexible prescribed geometrical design parameters, and adopts numerical optimization algorithms to perform phase error minimization. Numerical results compared with the published tri-focal and quadru-focal lenses demonstrate the merits of the proposed method. Second, an accurate and fast simulation method for the microwave lens has been developed to predict the phase, amplitude, array factor, and power efficiency performance. The proposed method is compared to both full-wave simulation and measurement. Comparable results have been achieved. Third, a novel method for a 360-degree scanning microwave lens is proposed. This concept uses the beam ports and the receive ports in an interleaving sequence such that adjacent ports alternate beam and receive functions. The result is a lens that produces scanned beams on opposite sides of the structure resulting in a 360-degree scanning range. The structure can use multiple opposing facets or continuous circular-port and radiating-element contours. To prove the concept, a four-facet microstrip lens has been designed, simulated, fabricated, and tested. The comparison between full-wave simulation and measurement has demonstrated good agreement. / Ph. D.
