Abstract

This paper concerns measurement procedures on an emotion monitoring stand designed for tracking human emotions in the Human-Computer Interaction with physiological characteristics. The paper addresses the key problem of physiological measurements being disturbed by a motion typical for human-computer interaction such as keyboard typing or mouse movements. An original experiment is described, that aimed at practical evaluation of measurement procedures performed at the emotion monitoring stand constructed at GUT. Different locations of sensors were considered and evaluated for suitability and measurement precision in the Human- Computer Interaction monitoring. Alternative locations (ear lobes and forearms) for skin conductance, blood volume pulse and temperature sensors were proposed and verified. Alternative locations proved correlation with traditional locations as well as lower sensitiveness to movements like typing or mouse moving, therefore they can make a better solution for monitoring the Human-Computer Interaction.

Abstract

There were tested microorganisms in differents soils at Admiralty Bay region. The physiological groups of microorganisms were restricted by the kind of organic matter. There were found in ornithogenic soils in higher number the following groups of microorganisms; proteolytic bacteria, uric acid and L-asparagine ammonifying bacteria, chitin degrading bacteria, lecithin degrading bacteria and calcium phosphate dissolving bacteria. The nitrifying bacteria were found in lower horizons of ornithogenic soils in higher number. The nitrogen fixing bacteria were found in mineral soils covered by plant associations, only. The spore-forming bacteria were detected in ornithogenic soils and in soil influenced by man.
