2. 6. Non-image-forming effects of light : Implications for the design of living and working environments

   Author : Mathias Adamsson; Thorbjörn Laike; Maria Johansson; Yvonne de Kort; Institutionen för arkitektur och byggd miljö; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circadian rhythms; circannual; light exposure; melatonin; cortisol; sleep-wake behavior; perception; mood; spectral composition; measurement;

   Abstract : Seasonal variation in mood and subjective well-being are common at geographical locations further away from the equator. The 24-h light-dark cycle is the main time cue for synchronizing the human circadian clock to the external day and night. READ MORE

4. 7. Nanoparticles: Characterization and exposure metrics

   Author : Linus Ludvigsson; Fasta tillståndets fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SEM; TEM; Nanoparticles; Aerosols; occupational exposure; CNTs; Fysicumarkivet A:2014:Ludvigsson;

   Abstract : Exposure to aerosol nanoparticles has always been present in the evolution of humans, and thus has the human body developed ways of dealing with particles that enters the body. However with the emerging nanotech industry, new types of nanoparticles are being produced and used. READ MORE

5. 8. Efficient strategies for collecting posture data using observation and direct measurement

   Author : Per Liv; Svend Erik Mathiassen; Marina Heiden; Leif Nilsson; Ingvar Bergdahl; Stephen Bao; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exposure assessment; arm elevation; exposure variability; variance components; random effects model; precision; bias; sample size; sample allocation; calibration; bootstrapping; Occupational and Environmental Medicine; arbets- och miljömedicin;

   Abstract : Relationships between occupational physical exposures and risks of contracting musculoskeletal disorders are still not well understood; exposure-response relationships are scarce in the musculoskeletal epidemiology literature, and many epidemiological studies, including intervention studies, fail to reach conclusive results. Insufficient exposure assessment has been pointed out as a possible explanation for this deficiency. READ MORE

6. 9. Bias and Precision in Biomechanical Exposure Assessment : Making the Most of our Methods

   Author : Jennie Jackson; Svend Erik Mathiassen; Eva Vingård; Mikael Forsman; Peter Johnson; Högskolan i Gävle; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; measurement strategy; accuracy; inclinometry; electromyography; EMG; upper arm; shoulder; low back; lumbar; thoracic; Health-Promoting Work; Hälsofrämjande arbete;

   Abstract : Background: Insufficient exposure assessment is a suggested contributing factor to the current lack of clearly characterised relationships between occupational biomechanical risk factors and musculoskeletal disorders. Minimal attention has been paid to the potential bias of measurement tools from expected true values (i.e. READ MORE

7. 10. Exposure assessment for the prevention of musculoskeletal disorders

   Author : Istvan Balogh; Avdelningen för arbets- och miljömedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yrkesmedicin; industrial medicine; Occupational health; heart rate; interindividual variation; index; arbetsmiljömedicin; job strain; Questionnaire; mechanical exposure;

   Abstract : Work-related musculoskeletal disorders of shoulder/neck are a major and increasing problem. Beside the pain, they involve high cost for the employer and society. The total expenditure for the musculoskeletal disorders of the neck and upper limb have been estimated to 0.5-2. READ MORE
