- Employees in nursing professions are at increased risk of developing musculoskeletal symptoms of the back. The level of physical stress for the nurse may depend on the type of patient. Nurses who mostly care for older people of restricted mobility are exposed to particularly high physical stress, one reason being that they must transport heavy loads when transferring patients. In addition, static physical postures and frequent bending and rotation of the upper body have been discussed in the literature as possible risk factors. In the present study, the personal CUELA measurement system was used to measure all adopted trunk postures and the movements of a qualified geriatric nurse on a geriatric ward over the course of three successive early shifts, in order to quantify the occurrence of awkward postures. The measurement results from this ward were compared with those from other hospital wards (for surgery and internal medicine). The nurse on the geriatric ward adopted an inclination of the upper body of greater than 20 degrees for an average of 1,390 times per shift. This was 25% greater than the value found for the volunteers in the wards for surgery and internal medicine (1,116 times). In the geriatric ward, almost 70% of the major inclinations of the trunk (above 60 degrees) were linked to work at the patient's bed, in comparison to 42% in the other wards. The results of these measurements suggest, for example, that consistent adjustment of the height of the bed could reduce the frequency and extent of major inclination of the trunk. Reduction in the physical stress from awkward postures can help to protect the health of employees in nursing professions.

- During the research project “Quality of Sustainable Buildings” (English: QSB, German: QNB), twenty seven buildings were investigated. Objective measurements (air quality CO2, air temperature, relative humidity) were performed and in addition, data on subjective judgements were collected using questionnaires. The analyses of this paper focus on the characteristics of ventilation (natural,mechanical and hybrid ventilation). Mechanically ventilated buildings indicated some advantages during the summer period with respect to the air temperature and in the winter with respect to the air quality (CO2). For naturally ventilated buildings, disadvantages during the winter were observed with respect to the air quality (CO2). The same buildings showed some advantage of a higher relative humidity in the winter period compared with the mechanically ventilated buildings. Subjective judgements did more or less correspond with the measured data. However, some parameters did not. Additional parameters for qualifying indoor air quality (here measured as CO2 - concentration) need to be considered. In addition, the study showed a quite good quality (measured and judged) for most of the buildings. In order to contribute to energy savings and to achieve a better level of indoor air quality(e.g. humidity), indoor air temperature could be reduced in winter without negatively affecting the comfort requirements of the office users.
