The development of autonomous robots has made a significant progress and first personal robots for common use start to appear. To use this robots, we need to develop applications and user interfaces to interact with them. The goal of this project is to make a universal interface for robot remote control. This work focuses on robots based on the ROS platform. This gives the final application a potential of use on other robotic projetcs running on ROS. The designed remote interface accomplishes two main purposes. The first is to show important data in a context of a 3D scene to help user understand the state of the controlled robot. And the second goal is to allow the user execute some basic manipulation with the robot. The final application was successfully adapted and tested on experimental robots Care-O-Bot and Turtlebot.

This work deals with the interactive interface for remote controlled robots and examines some of the existing visualization and simulation tools and robotic platforms. It also designs and implements interactive elements suitable for representation of detected objects, such as bounding box or billboard, and proposes interactive elements to eliminate some of the problems associated with remote control of the robot, such as bad perception of distances and the orientation in the environment. The interactive interface is implemented in the Robot Operating System using offered means for visualization, communication and operations management. Graphics primitives are represented by Interactive Markers that, in addition to the visualization, offers also possibilities of interaction. With these markers, a simple tool for controlling the movement of the robot is designed.

The popularity of floorball has been growing significantly. Floorball, as any other sport, is associated with certain health risks. Not only acute injuries but also chronic injuries have been connected with practicing sports. There is high risk of development of muscle imbalance, cumulative trauma disorders and chronic overuse, that negatively influence motor development of child. The aim of this diploma thesis was to evaluate the influence of corrective exercise on motor functions of young floorball players. Methodology: Two top Czech floorball teams of young boys has participated in the research. The observed group was composed of 79 players (Group A - 40 players, Group B - 39 players) aged 11 and 12 (the average age of 12,1 ± 0,6 SD). Short version of motor funciton test BOT-2 has been used to examine participants. Additional anamnestic data were used to run detailed analysis of factors influencing the test results. Results: The players of Tatran Střešovice and FbS Bohemians scored average percentiles of 63,45 ± 26,1 SD and 65,5 ± 27,8 SD respectively. That implies no impact of corrective exercise on results of motor funciton test (p = 0,74).However, the corrective exercise has decreased the risk of injury (p = 0,0183). The athletes playing for the team for more than 3 years have significantly...

This study aims to examine participation in the digital campaign #BlackoutTuesday to gain an understanding of the campaign's impact on university students’ awareness and participation in Black Lives Matter. Based on this, the study has two research questions: How have the students experienced that the #BlackoutTuesday campaign has affected their awareness of Black lives matter, and, for what reasons did the students feel that they participated in #BlackoutTuesday? With the help of slacktivism, networked publics, collective and connective action as the study's theoretical framework, we hope to gain a good interpretation of the results. To gather data, the study has used semi-structured interviews and to interpret the data, a thematic analysis has been used. The results that the study came to were that the students did not experience that their awareness was effected by #BlackoutTuesday. However, they still believed that they made a difference and that other people in their surrounding were affected in regard to awareness about Black Lives Matter. An unexpected discovery was also that many of the students connected Black Lives Matters, as an movement, solely to USA and not Sweden. The reasons for participation varied, but in this study, three main reasons were noted for the students participation. The reasons for participating were about the collective power, dissemination of information and taking a stand. With the results of the study we hope to create a better understanding of participation in similar campaign's and its effect on movements possibly society. However, more research is needed in this area to get a more thoroughly view of the field.

Hospitals are crucial aspects of society, run by incredible people that dedicate their life to caring for others. However, there are several tasks that are vital to a hospitals operation that do not require an empathic competence. One such tasks is the continuous resupply of consumable items needed to maintain necessary hygiene levels.   The Pluto concept act as a helping hand to the assistant nurses, relieving them and enabling them to spend more time with the patients and emphasizes their empathic, inherently human capabilities. The chief motivation is that nurses value the interaction with the patients the most in their work, which is also their primary task. However, they are charged with so many menial tasks that they have little time to care for their patients.

In this research project, the question of why some younger children appear to have better motor skills than older children is investigated. The hypothesis proposed is that children involved in physical activities after school or in the evenings have better motor skills at younger ages than children who are not involved in physical activities outside of school. Young children have very varied levels of motor skills competency that have developed due to living in different environments and having varied opportunity to be physically active. These differences are a result of factors like socioeconomic status, parental influence, climate, culture, etc.1 Sports and physical activities are usually executed in team settings, allowing children to develop important social skills like team work, leadership, sportsmanship, and responsibility among other ethical skills.2 But what if in addition to these numerous benefits, physical activity throughout childhood also offered an improvement in the rate of development of motor skills? One hundred and thirty-five students in grades K-5 participated in a program looking at perception, cognition and motor skills. There were no exclusion criteria for the study and all children were invited to participate.  A total of 95% of the kids participated in the study. This study focuses on a portion of a larger study that was completed prior to the start of the program. Children’s motor skills were evaluated with a standardized measure Bruininks-Oseretsky Test of Motor Proficiency (BOT-2). Three sections of the (BOT-2) were implemented: running speed and agility, balance, and upper limb coordination. The scores were analyzed along with self-reported surveys on the levels of physical activity of the children. The results showed evidence to support an association between the amount of physical activity outside of school, either after or in the evenings, r = .621, p = .001. An association was also seen between the amount of time spent in physical activity after school/evenings and running speed and agility scores, r = 0.295 and 0.269 p=.001. This work will be useful in understanding the relationship between children’s participation in physical activity after school and motor skill development rate. The information gathered from this research can be used to promote and support the increase of physical activity time that is available to students during school. Allowing children to have more experiences and opportunities of physical activity at school can help minimize any disadvantage in the rate of motor skills development that children who are not physically active at home may have.

Artificiell intelligens har varit ett omdiskuterat ämne sedan decennier tillbaka och vävs desto mer in i vår vardag allt eftersom tiden går. Vi kan som åskådare bara se på medan vår vardag både kantas, förgylls och radikaliseras av denna teknik som ständigt utvecklas. I denna kvalitativa studie så undersöks det hur chattbotar (även kallade textuella botar) uppfattas av konsumenten inom kundtjänst. Syftet med denna studie är att undersöka konsumenters upplevelsers, möjligheter och problem när det gäller chattbotar inom kundtjänst. Undersökningen bestod av totalt 12 respondenter som medverkade i strukturerade intervjuer. Intervjufrågorna delades in i 4 kategorier (Inledning, användarupplevelser, effektivitet och kundnöjdhet). Kategoriseringarna ämnade att spegla de aspekter som studien indelades i. Resultaten indikerade att en majoritet av respondenterna föredrog att kontakta kundsupport via telefon istället för chattbot. Respondenterna uppgav också att kravet på att precisera sin frågeställning ökade i kontakten med en chattbot. Resultaten påvisade också att den upplevda effektiviteten påverkads av mängden information som uppvisades samt att kundnöjdheten påverkades negativt efter betjänandet av en chattbot. Respondenternas svar visar att fördelar med en chattbot är den konstanta tillgängligheten, den snabba responstiden samt avsaknaden av väntetid. Resultaten indikerar att en dåligt anpassad och chattbot kan bidra till försämrade användarupplevelser bland konsumenter. Emellertid så indikerar även resultaten att den konstanta tillgängligheten hos en chattbot är något som ökar kundnöjdheten. Detta skulle kunna vara en positiv förbättring för ett företag, detta då företagets tillgänglighet ökar och ger konsumenter möjlighet att få sina ärenden besvarade även utanför kontorstid. Studien påvisaratt det är viktigt för företag som funderar på att implementera en chattbot att beakta vilken informationen som visas samt att ha en väl utprovad och genomtänkt struktur på chattboten.

BACKGROUND: Most women within reproductive ages living in Low- and Middle-Income Countries, have limited or no access to education on sexual and reproductive health and contraception, yet about 1.9 billon women in LMICs own a mobile phone. The exposure to digital health services has the potential to contribute to improving awareness, influencing positive perceptions, beliefs and promoting SRH and contraception.AIM: To explore user views and perceptions on the Grace Health’s (a digital health service) ability to improve awareness on sexual reproductive health and contraception among Ghanaian, Nigerian and Kenyan women aged 18-35.METHODOLOGY: A qualitative design using phenomenography to interview women remotely on women’s perception of digital health services through their own experience with using the Grace health chat bot and app. Also, their views were sought on how other women are gaining awareness and impacts on sexual reproductive health and contraception from the digital health services.RESULTS: Seven categories on digital health services emerged, with key findings presented as Safe days, ovulation as contraception, impacts on SRH, Avoiding or seeking pregnancy and influence on perception.CONCLUSION: This qualitative study gives insight for research community, public health professionals, app designers, health care providers, stakeholders and civil society organisations in making decisions regarding the use of digital health service as strategic, innovative instruments for interventions in major key indicators of Sexual Reproductive Health and Rights.
