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:: In this study, the change in the synchronization between heartbeat and music was investigated. The phenomena of the synchronization between human heartbeat and musical tempo has been reported in several previous studies, however, it has not yet been fully investigated including the effect of changing the tempo of musical piece on the synchronization. In the experiment, the subjects were exposed to musical pieces in which the tempo was manipulated to gradually increasing (named “Up” condition), decreasing (“Down”) and constant (“Flat”). Through the analysis by our developed software, Cardio-Music Synchrogram, the shortest length of the total synchronization periods was observed in Flat condition. Furthermore, the temporal change in the synchronization was investigated.

Opis:: Recent behavioural medicine studies have revealed that the human secretory substances change according to his/her mental states. Especially, those substances transiently get increase (or decrease) against the short-term experimental stressors. However, the relation with rather longer stressor, or daily stressor, has not yet well understood or reported discrepant results. One possible reason for this discrepancy might be brought from uncertainty of the psychological evaluation, which is the score of subjective questionnaire. We then introduced an evaluation criterion of attributes based on rough set theory to analyze the relation between the psychological state and a major immune substance. As a result, several items in the questionnaire were extracted as dominant items, while there was still no correlation between them.

Opis:: The effect of pleasant and unpleasant odor on human physiological state was preliminary investigated by assessing salivary substances. A term ”pleasant“ (or unpleasant) is rather showing one's subjective and thus mental state meanwhile the odor itself should give an impact to both human mind and body. This study was aimed at investigating an effect of pleasant/unpleasant odors on human body and mind. In the experiment the odor of isovaleric acid, as an unpleasant odor, and Japanese cypress, as a pleasant one, were exposed to subjects for 18 minutes. Salivary immune substance (Immunoglobulin A: IgA) and glucocorticoid (cortisol) were determined every three minutes as for an indices of the impact of the odors on human immune and endocrine secretion. As a developing result, IgA showed an increase by isovaleric odor whilst cortisol decreased, even though the concentration of that unpleasant odor was too low to be aware of. These changes in the secretion of the substances were discussed in relation with human physiological stress reaction mechanism.

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:: We developed a music-heart beat feedback system to test the efficacy of the entrainment between music and human heart beat. As a result of regulating the music tempo as 10% faster (namely FAST condition) or slower (SLOW) than heart beat in a real time series, the subjects’ heart rate was successfully modulated as significantly higher in the FAST condition and lower in the SLOW condition. The timeliness regulation of this feedback system may play a key role to bring forth the music-heart beat entrainment.

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.

Opis:: Knowledge is a key factor to the personal success. The certifications are the instant tools that are commonly available to assess the personal success. In an e-Learning environment, where the learning projects are delivered with the aim to provide a professional or an academic certification, it is integral that the Learning Management Systems provide security features that will ensure the credibility of the online real-time assessments and the certification. In a conventional examination environment, there will be invigilators to overlook the examinees, on the contrary, in an on-line examination environment; it is vital that an invigilation mechanism is implemented to ensure the integrity of the examination. In this article we present a face based access control system for online e-Learning systems.

Opis:: There is growing evidence suggesting that the magnitude of cortisol awaking response (CAR), which is characterized by a profound increase of salivary cortisol secretion after awakening, plausibly reflects the level of a chronic stress, social stress, anxiety, etc. In this study the alternation of CAR at the start and at the end of two weeks session of self-instruction for good sleep was investigated; by which we anticipated that the self-instruction for good sleep would bring-forth a positive affection for the participants, and would result in decline of cortisol awakening response (CAR). Nevertheless, as a result unexpectedly, subjects did not change their sleep and dietary habits along with the instruction, moreover the increased CAR was observed. This result implies that the suggestion of an impractical instruction would solely be taken as a stressful task for participants, even though they know that it is effective to improve their sleep. On the contrary, if one develops an instruction with practicable indication for daily life, it is highly possible to observe a positive effect of the instruction on CAR.

Opis:: An exciton confined within a quantum dot acts as a two-level quantum system, and is one of the most promising candidates for quantum computing and quantum information processing. The real-space optical probing of the quantum eigenstates in a single quantum dot and coupled quantum dots should be developed toward the realization of quantum photonic devices, where their wave functions are dynamically controlled by coherent optical techniques. Here we apply near-field photoluminescence imaging spectroscopy with a high spatial resolution of 30 nm to map out the centre-of-mass wave function of an exciton confined in a GaAs quantum dot. The spatial profile of the exciton emission, which reflects the shape of a monolayer-high island, differs from that of biexciton emission, due to different distributions of the polarization field for the exciton and biexciton recombinations.

Opis:: Two contrasting approaches toward an epidemic study were illustrated as a pilot study; the regression analysis which is rather conventional methodology used in the past/present epidemic studies, and the other is the classifier analysis which is in the soft computing toolbox. The dataset we used for this study is obtained from a part of a cohort study which principally focused on a fatigue syndrome of the elementary and junior high school educates. In the classifier analysis we employed a major supervised machine-learning algorithm, K-Nearest Neighbour (K-NN), coupled with Principal Component Analysis (PCA). As a result, the performance that was found by cross validation method in the classifier analysis provides better results than that of the regression analysis. Finally we discussed the availability of both analyses with referring the technical and conceptual limitation of both approaches.

Opis:: Color is an inseparable element of our lives and is a part of everything we perceive. Colour has a strong impact on our decision making process. Therefore there is a direct connection between the colour and psychological functions. Kansei is a Japanese concept, which abstracts the subjective internal process in the brain, which is activated by external stimuli. Furthermore, Kansei is a function of the brain which integrates sensibility, sense, sensitivity, aesthetics, emotion, affection and intuition. Therefore measuring Kansei is a broader aspect of measuring psychological functioning of the brain. In this research, colour interaction and respective psychological functioning is measured using Kansei measurement method. Further the result of this research was compared with an circumflex model for personality and emotions to recognize the variability of colours in terms of emotional regions. The results indicate that colours have a variable nature and are associated with several different emotions in several different intensities. Colours which have longer wavelengths are more arousing and they generate more psychological functioning than the colours which have shorter wavelengths.

Opis:: Noctiluca scintillans is an important member of the mesozooplankton in terms of biomass and production in the Seto Inland Sea, Japan. The densities and adenosine triphosphate (ATP) contents of N. scintillans cells were measured. Vertical profiles of N. scintillans cellular activity in the coastal water were determined and the ATP contents were high at middle layers, with a maximum depth of 10 m. ATP contents were low in the surface and lower layers. These results suggest that active N. scintillans cells in subsurface layers with low density play an important role in the coastal ecosystem, and high-density cells in the surface water are not active.
