Ergonomics requirements for personal vehicles for persons with disabilities
Maciej Sydor, Marek Zabłocki, Marcin Butlewski

Independent mobility is significant for everybody’s quality of life; it is especially important for people with disabilities. This article presents ergonomics guidelines for adapting individual cars to meet the needs of drivers with disabilities and their passengers. The solutions have been described for individual cars and for universal cars for transporting any user of a wheelchair. This article ends with a confrontation of the guidelines with the principles of ergonomics.



Ergonomic-technical guidelines that consider the needs of disabled persons for public transport vehicles
Marek Zabłocki, Marcin Butlewski, Maciej Sydor

Modern means of public transport should consider the needs of all users. This article presents ergonomics guidelines and legal requirements for the accessibility of public transport for people with special needs. It defines the main problem areas, and then compares them with the principles of universal design. Numerous sources helpful in identifying the needs of people with disabilities are presented. An open catalog of sample ergonomic solutions ends this article.



Supported employment as a way of helping persons with disabilities become active in the labour market
Anna Kławsiuć-Zduńczyk, Ewelina Mechuła

This article discusses making persons with disabilities active in the labour market, from which they are excluded.  
Employment opportunities for such persons are still limited while their occupational activity can undoubtedly bring both
economic and social benefits to both them and the society.
Supported employment is one way to help persons with disabilities in finding a job.

Double-layered active structure for reducing noise transmission through sound insulating barriers
Leszek Morzyński, Tomasz Krukowicz

Sound insulating enclosures are a basic technical measure commonly used to reduce noise. Insulation of passive sound insulating barriers, however, decreases with a decrease in frequency. Insulation in the low frequency range can be increased by using active noise control methods. This article presents the structure and principle of operation of a double-layered active structure to limit the transmission of noise through barriers. An algorithm, which extrapolates the error microphone signal based on signals from the vibration transducers, is used for structure control. This article presents structure performance in laboratory conditions.
