  2. 1. Office work and physical factors : health aspects of electromagnetic fields and light

    Author : Monica Sandström; Kjell Hansson Mild; Gunnar Nordberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Facial skin symptoms; office illness; electrical hypersensitivity; physical environment; flicker; jitter; neurophysiological effects;

    Abstract : The overall aim of this thesis is to increase our knowledge of the physical environment of office workers with special focus on electromagnetic fields and to address the question of whether electromagnetic fields can directly or indirectly contribute to symptoms or discomfort among video display terminal ( VDT) workers. Furthermore, we have measured light modulation from various commonly used light sources in laboratory conditions and, as a second step, used modulated light as stimulus for provocation of neurophysiological responses in persons with perceived “electrical hypersensitivity” (EHS).

    Abstract : Mental disorders pose a significant global health challenge. To effectively address this challenge, mental health promotion must be included in various sectors, including workplaces. Various strategies for promoting mental health in the workplace have been suggested, including interventions aimed at improving movement behavior, i.e. READ MORE

  5. 3. Whiteness and Fluorescence in Layered Paper and Board : Perception and Optical Modelling

    Author : Ludovic Gustafsson Coppel; Per Edström; Caisa Johansson; Markku Hauta-Kasari; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Whiteness; Perception; Colour Appearance Modelling; Paper Optics; Light Scattering; Fluorescence; Lateral Light Scattering; White-Top Mottle; Kubelka-Munk; Radiative Transfer;

    Abstract : This thesis is about modelling and predicting the perceived whiteness of plain paper from the paper composition, including fluorescent whitening agents. This involves psychophysical modelling of perceived whiteness from measurable light reflectance properties, and physical modelling of light scattering and fluorescence from the paper composition.

  6. 4. Active workstations : a NEAT way to prevent and treat overweight and obesity?

    Author : Frida Bergman; Tommy Olsson; Ann Sörlin; Carl-Johan Boraxbekk; Patrik Wennberg; Fredrik Öhberg; Mats Börjesson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; treadmill workstations; sedentary behaviour; light-intensity physical activity; non-exercise activity thermogenesis; office workers; obesity;

    Abstract : Background: Modern society is triggering sedentary behaviours in different domains. Different strategies can be used to reduce the time spent sitting and increase physical activity in the office environment, which is one domain where sedentary time is often high. One such strategy could be to install treadmill workstations. READ MORE

  7. 5. Dialogen i socialt arbete : en studie av socialbyråsamtal i ljuset av modern dialogteori
