Self-reported physical disabilities in children in the Netherlands

Purpose: To assess the prevalence of self-reported physical disabilities in school children, through the Child Health Monitoring System. Methods: In 1992/1993, data were obtained in mainstream education (n = 5484), and in 1994/1995 in special education (n = 2622). The data were weighted to calculate estimates representative of the Dutch...

The relationship between leisure time, physical activities and musculoskeletal symptoms and disability in worker populations

Objectives: To assess the association between leisure time physical activity and musculoskeletal morbidity, as well as possible interactions with physical activity at work. Methods: A literature search was performed to collect all studies on musculoskeletal disorders in which physical activity was involved as a variable. Next, an analysis was...

Effects of two types of intra-team feedback on developing a shared mental model in Command & Control teams

In two studies, the effect of two types of intra-team feedback on developing a shared mental model in Command & Control teams was investigated. A distinction is made between performance monitoring and team self-correction. Performance monitoring is the ability of team members to monitor each other's task execution and give feedback during task...

Kwaliteit van leven bij kinderen met sikkelcelziekte in de regio Amsterdam [Quality of life of children with sickle cell disease in the Amsterdam area]

Objective. To determine the differences in quality of life between children with sickle cell disease and healthy immigrant children. Design. Descriptive, comparative. Method. The quality of life of children with sickle cell disease between 5 and 15 years old being treated in the Emma Children's Hospital AMC in Amsterdam, the Netherlands, was...

Measuring disability, the agreement between self evaluation and observation of performance

Purpose: In 1981, eight countries and the World Health Organization (WHO) reached consensus about applying a similar disability questionnaire in their health surveys that was related to the ICIDH. In 1992 a revised version, the WHO-disability questionnaire, was recommended. In this paper the concurrent validity of 10 items of the questionnaire...

Coping with pain in the hip or knee in relation to physical disability in community-living elderly people

Objective. To investigate the use of pain coping strategies by community-living older people with pain in the hip or knee and the mediating role of coping with pain in the relationship between the chronicity of pain and physical disability. Methods. A group of 157 people with pain 'in the last month' was identified. Coping with pain was assessed...

Categorization of road environments and driving speeds

Several studies indicate that road users are not able to distinguish roads according to official road categories. As a means of designing a sustainably safe traffic environment the concept of Self-Explaining Roads (SER) has been developed. In order to support safe driving behaviour and appropriate speed choice drivers should be enabled to...

Measuring health-related quality of life in children: The development of the TACQOL parent form

Health-related quality of life (HRQoL), conceptualized as patients' own evaluations of their health status, is an important criterion in evaluating health and health care and in the treatment of individual patients. Until now, few systematic attempts have been made to develop instruments to assess the HRQoL of children using such a...

Gunstige ervaringen met intraveneuze antimicrobiele therapie buiten het ziekenhuis [Good results of intravenous antimicrobial treatment outside the hospital]

Objective. To determine whether intravenous home treatment with antimicrobial drugs of patients with an infection is feasible. Design. Descriptive. Setting. Academic Hospital, Leiden, the Netherlands. Method. In October 1992 a programme for intravenous home treatment of patients with infectious diseases was started. The programme was based on...

A puzzling percept of stimulus stabilization

A visual illusion is reported which comprises the following: when a monitor with a moving constant velocity grating is swayed in front of a subject, the grating may be perceived as freezing or decelerating on the screen. This percept appears to depend on the magnitude and direction of the retinal grating velocity, relative to that of the moni...

Formulation parameters influencing self-stratification of coatings

Research was carried out aimed at the development of self-stratifying paints for steel which after application during film formation spontaneously form two well established layers of primer and top coat. The parameters affecting stratification were investigated for combinations of epoxy resins and physically drying binders. Incompatibility of...

Trends in hospital admissions among children aged 0-19 years with type I diabetes in The Netherlands

OBJECTIVE - To determine the number and duration of hospital admissions due to diabetes in children aged 0-19 years between 1980 and 1991. RESEARCH DESIGN AND METHODS - Secondary analysis of data collected by the SIG Health Care Information was based on the 9th revision of the International Classification of Diseases. The subjects were all...

Arthrokinetic information affects linear self-motion perception

A sensation of linear self-motion can be induced in a blindfolded stationary sitting subject, who keeps contact with a linearly moving platform (acceleration 0.1 m/s²) in the frontoparallel plane by means of a hand-over-hand walking action. When discordant suprathreshold vestibular information from the otoliths is added by moving the subject...

Quality and effectiveness of occupational health services evaluated by the providers

In a debate on the desired occupational health service in The Netherlands all parties involved seemed to be rather unsatisfied with the current practice. Therefore a study was set out on the quality of the service to 51 client organizations as seen by the parties involved. In the first phase the viewpoint of the occupational health teams was...

Self-assessment of faecal pH and faecal bulk in epidemiological studies

Theory of self-locking phenomena in the pressure broadened three-mode He-Ne laser

Taking account of pressure broadening the coefficients in Lamb's third-order amplitude and phase determining equations for three modes are evaluated in the Doppler limit, and comparison is made with other theories. After expanding the coefficients to first order in the detuning ε from the linecenter an expression is presented for the frequency...
