The adaptive modeling of chemical attack on concrete for the prediction of durability and for the quality control of concrete structures requires the assessment of the concrete moisture content. Two sensors were designed to determine the permittivity which is related to the moisture content. These relations can be obtained from a calibration procedure. The applicability of the sensors was investigated in a field experiment on a test-building. First long-term results are reported.

The early after surgery rehabilitation has an enormous somatic and psychological importance for patient. In the after surgery phases of injured vertebral column with spinal damage stabilisation, the ordinary rehabilitation treatment is concentrated on patient positioning on the bed and also for training of sitting position with perspective transfer to wheelchair.
The aim of presented work was to tray the possibilities of early rehabilitation of paraplegic's patients in vertical plane with imitation of physiological movement of extremities.

This paper describes a new nursing support system at home in the night. The system non-restrictively monitors patients on the bed. An air mattress laid out on the bed, a fine pressure to detect the pressure in the air mattress and filters are the components of the system. The human body movements such as the heart beat, respiration, snoring, turning over and coughing directly to the pressure in the mattress and causes of the body movements can be discriminated by the proper filtering.
Physical conditions of the patient can be diagnosed by bio-information above. When he is in an emergent situation, he might turn over very frequently. The continuos monitoring helps to find his sudden physical change, which considerably reduce the effort of nursing. Further when the patient is in a normal condition, the continuos measurement of the bio-information above provides the important health information.

The contribution shows the principle and construction of the areal bioimpedance equipment, which enables the evaluation of the dynamic course of bioimpedance in different parts of the body. The principle of the areal bioimpedance equipment is based on the measuring of bioimpedance by a four-electrodes impedance (resistivity) measuring method. The two-dimensional dynamic picture of the bioimpedance is obtained by tracing the bioimpedance in a rectangular net. The construction of the areal bioimpedance equipment issues of the realised experiments and measurements. The equipment enables the extension of the application range of bioimpedance methods not only for tracing the haemodynamic of the heart and big arteries, but also of the tissues and organs.

The aim of the study is the recognition on the voice-prints of vocal vowels using instrument and control engineering method in order to utilize for CIM, security system, the evaluation of the vocal training and the voice compensation for voice handicapped persons. The five stages evaluation on the vocal voice is decided by a professor of the department of music for the lived voice and output of DFT. The authors obtain three dimensional diagrams composed of the frequency, the spectrum and time using DFT.
