Opis:
The Recent rapid growth of the information technology aid people to improve the performance in processing their job activities. These changes, in turn, force them to carry out their job activities using computers in the workplace; that results in the increase of somatic and/or mental stresses. In this study, we conducted a preliminary experiment to estimate an impact of web-browsing on human mind and body. Two types of web-browsing tasks, which are a 18-minuetes of continuous web-browsing and an intermittent web-browsing (first 45 second of each 1-minutes interval), were given to the subjects (10 healthy male aged from 20-23) with within-subjects experimental design. With regard to physiological measures, two prominent stress biomarkers, salivary immunoglobulin A (IgA) and cortisol, were employed. Comparing among the task conditions, relatively larger and long-lasting increase of IgA and smaller decrease of cortisol was observed with an intermittent web-browsing despite there was no difference in the psychological state. These results illustrate the difficulty of estimating the mental workload caused by web-browsing and the importance of employing physiological indices.

Opis:
Our experience tells us the power of music on human body and mind. Moreover a series of psycho-physiological studies has revealed the positive effects of music on human autonomous nervous system such as alleviating the symptom of the hypertension. However little has been known about the effects of music on human endocrine system, which plays the dominant role for forming our life. In this study, the effect of music on the secretion of the salivary cortisol, a major glucocorticoid hormone, was investigated in a laboratory experiment. In a stream of stress psycho-physiological study, cortisol is considered as a feasible stress biomarker. In the experiment ten healthy male students were exposed to music, noise, and silence condition followed by a simple but stressful calculation task. As a result, the significant difference in the cortisol responses among the condition was observed; the salivary cortisol was decreased after the music treatment. This result plausibly demonstrated the effects of music on human hormonal secretion and might imply the power of music.

Opis:
This paper was aimed at evaluating the mental work-load (MWL) with psycho-physiological indices. Especially, we focused on the intermittent type of MWL, which is assumed as a predisposing factor of various somatic and mental disorders. In the experiment, we introduced a facial skin thermo image comparing with conventional physiological indices, such as electrocardiogram (ECG) and electroencephalogram (EEG). As a result, the facial skin image was suggested to be a useful tool for evaluating such an intermittent type of MWL.
