Exploring Different User Interfaces for Velocity based Training using Smart Gym Machines : Pilot Study
- 2021
-
In: ICT4AWE 2021 - Proceedings of the 7th International Conference on Information and Communication Technologies for Ageing Well and e-Health. - 2184-4984. - 9789897585067 ; 2021-April, s. 113-120

Conference paper (peer-reviewed)abstract
- With the emerging technology called the Internet of Things (IoT), we can now connect computing devices and sensors to the Internet. The IoT sensors serve to collect data, pushing it and sharing it with a whole network of connected devices. We decided to explore how to utilize IoT data to increase the user experience from a commercial gym application called Advagym. Advagym is a commercial solution already available in the market, which aims to digitize the gym experience, where a retrofit solution is used to fit IoT devices on gym machines to track performance data from users’ workouts. The main goal of this paper is to utilize IoT data from Advagym’s IoT sensors for velocity-based training (VBT) and conduct a comparative study of three different user interfaces presenting VBT data to increase the user experience. The main contribution of this paper is an analysis of user preferences regarding the user interface of VBT feedback during a gym workout.

Impact of COVID-19 Lockdown in Eating Disorders : A Multicentre Collaborative International Study
- 2022
-
In: Nutrients. - : MDPI AG. - 2072-6643. ; 14:1
-
Journal article (peer-reviewed)abstract
- Background. The COVID-19 lockdown has had a significant impact on mental health. Patients with eating disorders (ED) have been particularly vulnerable. Aims. (1) To explore changes in eating-related symptoms and general psychopathology during lockdown in patients with an ED from various European and Asian countries; and (2) to assess differences related to diagnostic ED subtypes, age, and geography. Methods. The sample comprised 829 participants, diagnosed with an ED according to DSM-5 criteria from specialized ED units in Europe and Asia. Participants were assessed using the COVID-19 Isolation Scale (CIES). Results. Patients with binge eating disorder (BED) experienced the highest impact on weight and ED symptoms in comparison with other ED subtypes during lockdown, whereas individuals with other specified feeding and eating disorders (OFSED) had greater deterioration in general psychological functioning than subjects with other ED subtypes. Finally, Asian and younger individuals appeared to be more resilient. Conclusions. The psychopathological changes in ED patients during the COVID-19 lockdown varied by cultural context and individual variation in age and ED diagnosis. Clinical services may need to target preventive measures and adapt therapeutic approaches for the most vulnerable patients.

From carbohydrates to fat : Trends in food intake among Swedish nutrition students from 2002 to 2017
- 2020
-
In: PLOS ONE. - : Public Library of Science. - 1932-6203. ; 15:1, s. 1-14
-
Journal article (peer-reviewed)abstract
- Earlier studies have implied a change in dietary habits of the Swedish population towards a low carbohydrate, high fat diet. Questions have been raised about the development in recent years and potential health effects. We have investigated the dietary intake of Swedish female students enrolled in a university nutrition course between 2002 and 2017. The students carried out self-reporting of all food and drink intake over one weekday and one weekend day. Intake of macronutrients (E%) and micronutrients were calculated for the whole period while statistical analysis was performed for changes between 2009 and 2017 (729 women). Results showed significant changes in carbohydrate intake (from 47.0 to 41.4 E%) and fat intake (from 31.7 to 37.5 E%). Carbohydrate intake was significantly lower than the Nordic Nutrition Recommendations (45-60 E%). However, daily fiber intake remains high (3.0 g/MJ) in a national context, and intake of vitamin D and folate appears to increase during the period. The results suggest that the observed national transition from carbohydrate to fat intake persists, and that it might be especially evident among individuals interested in food and nutrition. Considering the fiber and micronutrient intake, the change is not necessarily unfavorable for this particular group.

A novel method for calibration of AF4 channels for hydrodynamic radius determination : the nanoemulsion method (featuring MALS)
- 2018
-
In: Journal of Chromatography A. - 0021-9673. ; 1533, s. 155-163
-
Journal article (peer-reviewed)abstract
- This study suggests a novel method for determination of the channel height in asymmetrical flow field-flow fractionation (AF4), which can be used for calibration of the channel for hydrodynamic radiusdeterminations. The novel method uses an oil-in-water nanoemulsion together with multi angle lightscattering (MALS) and elution theory to determine channel height from an AF4 experiment. The methodis validated using two orthogonal methods; first, by using standard particle elution experiments and, sec-ondly, by imaging an assembled and carrier liquid filled channel by x-ray computed tomography (XCT). It is concluded that the channel height can be determined with approximately the same accuracy aswith the traditional channel height determination technique. However, the nanoemulsion method canbe used under more challenging conditions than standard particles, as the nanoemulsion remains stablein a wider pH range than the previously used standard particles. Moreover, the novel method is also morecost effective.

Conference paper (other academic/artistic)abstract
- While the Swedish nutrition recommendations have been kept relatively constant in recent years, public attitudes to different diets have been swinging faster. The National food survey (Riksmaten), being performed in Sweden only once per decade, cannot identify any corresponding rapid changes in diets. Hence, our understanding of potential fluctuations is limited. During the last 15 years, nutrition students at the Linnaeus University (formerly University of Kalmar) have reported their food intake in the context of the course Diet, Nutrition and Health 7,5 hp. The result is an extensive data set comprising more than 1100 individuals and over 2500 days of food intake reports, and although not originally intended or designed as a study, it became apparent that these data could be of interest as an indicator for national dietary trends. Food intake was reported (by weighing or estimating the amounts) for two weekdays and one weekend day per student, along with age, length, sex and weight. Food intake was translated to nutrient intake using Dietist Net software (Kost & Näringsdata). Admittedly, the data set has some validity problems: the students differ from the Riksmaten study groups in mean age and geographical distribution, and all data was collected during March-April. As students in a nutrition course, they can also be expected to be more interested and more knowledgeable in the nutrition subject than the average person. Nevertheless, the results clearly demonstrate a substantial change in nutrient intake from 2006 and onwards, where the energy from carbohydrates decreased from above 50% to below 40%, and where the energy intake from fat increased from about 25% to 36%. Further details, such as the effects on the intake of selected micronutrients, will be presented.

The use of networks as a strategic approach of micro-enterprises in the agri-food sector
- 2014
-
In: International Journal of Entrepreneurship and Innovation. - 1465-7503 .- 2043-6882. ; 15:3, s. 169-178
-
Journal article (peer-reviewed)abstract
- Increasing competition and regulatory changes place micro-sized enterprises (MSEs) in the agri-food sector under strong competitive pressure. Smallness may be a substantial barrier to success. Previous research suggests that networks can be used strategically to combat these constraints. However, there is a lack of understanding of the extent to which this finding may be applicable to MSEs and the local agri-food sector. Based on eight in-depth interviews of agri-food MSEs, it is concluded that MSEs apply networks to strengthen their competitive advantage – for example, by forming stronger customer relationships. The MSEs are using their networks to combat their size-related disadvantages, but not by growing; rather, the networks enable them to remain small and independent while further strengthening their position as small producers.
