  • Workplace wellness

    serch.it?q=Workplace-wellness

    Workplace wellness is any workplace health promotion activity or organizational policy designed to support healthy behavior in the workplace and to improve health outcomes. Known as 'corporate wellbeing' outside the US, workplace wellness often comprises activities such as health education, medical screenings, weight management programs, on-site fitness programs or facilities. Workplace wellness programs can be categorized as primary, secondary, or tertiary prevention efforts, or an employer can implement programs that have elements of multiple types of prevention. Primary prevention programs usually target a fairly healthy employee population, and encourage them to more frequently engage in health behaviors that will encourage ongoing good health. Example of primary prevention programs include stress management, and exercise and healthy eating promotion. Secondary prevention programs are targeted at reducing behavior that is considered a risk factor for poor health. Examples of such programs include smoking cessation programs and screenings for high blood pressure or other cardiovascular disease related risk factors.

  • Iris recognition

    irises of an individual's eyes.Iris recognition is an automated method of biometric identification that uses mathematical pattern-recognition techniques on video images of one or both of the irises of an individual's eyes, whose complex patterns are unique, stable, and can be seen from some distance. Retinal scanning is a different, ocular-based biometric technology that uses the unique patterns on a person's retina blood vessels and is often confused with iris recognition. Iris recognition uses video camera technology with subtle near infrared illumination to acquire images of the detail-rich, intricate structures of the iris which are visible externally. Digital templates encoded from these patterns by mathematical and statistical algorithms allow the identification of an individual or someone pretending to be that individual. Databases of enrolled templates are searched by matcher engines at speeds measured in the millions of templates per second per (single-core) CPU, and with remarkably low false match rates.

  • Screening (medicine)

    A coal miner completes a screening survey for coalworker's pneumoconiosis.Screening, in medicine, is a strategy used in a population to identify the possible presence of an as-yet-undiagnosed disease in individuals without signs or symptoms. This can include individuals with pre-symptomatic or unrecognized symptomatic disease. As such, screening tests are somewhat unusual in that they are performed on persons apparently in good health. Screening interventions are designed to identify disease in a community early, thus enabling earlier intervention and management in the hope to reduce mortality and suffering from a disease. Although screening may lead to an earlier diagnosis, not all screening tests have been shown to benefit the person being screened; overdiagnosis, misdiagnosis, and creating a false sense of security are some potential adverse effects of screening. Additionally, some screening tests can be inappropriately overused. For these reasons, a test used in a screening program, especially for a disease with low incidence, must have good sensitivity in addition to acceptable specificity.
