1. 1. Ambulance Work : Relationships between occupational demands, individual characteristics and health-related outcomes

   Författare :Ulrika Aasa; Ewa Wigaeus Tornqvist; Umeå universitet; []
   Nyckelord :ambulance; autonomic reactivity; body size; cortisol; demand-control-support; emergency personnel; fitness; gender; heart rate variability; low-back pain; neck-shoulder pain; occupational; physical capacity; work simulated test; worry; Occupational and Environmental Medicine; arbets- och miljömedicin;

   Sammanfattning : Although musculoskeletal disorders (MSDs) and other health complaints are an occupational problem for ambulance personnel, there is a lack of knowledge regarding work-related factors associated with MSDs and other health complaints. The overall aim of this thesis was to investigate the relationships between occupational demands, individual characteristics and health-related outcomes among ambulance personnel. LÄS MER

3. 2. Thermal Issues in Testing of Advanced Systems on Chip

   Sammanfattning : The overall aim of this thesis was to identify valid, simple, and inexpensive physical tests that can be used for evaluation of firefighters’ physical work capacity. Paper I included fulltime- and part-time firefighters (n = 193), aged 20-60 years. LÄS MER

5. 4. Identification and validation of risk factors in cold work

   Författare :Lina Giedraityte; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

   Sammanfattning : There are very few methods available for the assessment of cold exposure and they rely more or less on complex equations for calculating heat balance; therefore, there is a need for new practical methods for the identification and control of cold hazards in workplaces. In the first study, the aim was to test a checklist which enables cold risk assessment based on observations in the workplace. LÄS MER

7. 5. Flight Test System Identification

   Författare :Roger Larsson; Martin Enqvist; Lennart Ljung; Roy Smith; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : With the demand for more advanced fighter aircraft, relying on unstable flight mechanical characteristics to gain flight performance, more focus has been put on model-based system engineering to help with the design work. The flight control system design is one important part that relies on this modeling. LÄS MER
