The purposes of this study were to select the crude drugs of the medicated baths calendar for each of the twelve months of the year, and to clarify the physiological responses of this medicated baths. To ultimately establish a set of crude drugs for use in medicated baths, the history and make-up of medicated baths were researched and the characteristics of seasonal events were investigated. Next, characteristics of crude drugs particular to each Japanese season that would affect baths and formulation our bath drugs using readily accessible materials were sought. The result was an assortment of crude drugs specifically designed for effectiveness throughout the year. In experiments, skin temperatures, blood flow, and amounts of perspiration were monitored. The findings revealed that the medicated baths were highly effective in keeping the skin temperature high in that they caused a little decrease in mean skin temperature over a period of time and a longer period of perspiration in comparison to normal bath. These medicated baths were also found to increase the amound of blood flow and the secretion of nor adrenaline, making the drugs a notably more effective promoter of blood circulation than normal bath. The results proved the medicated baths to be beneficial, healthy bathing methods.

Pachinko is a popular form of recreation in Japan. However, in recent years, along with Pachinko’s popularity, “Pachinko dependence” has become topical news. The purpose of this study was to investigate beta-endorphin, catecholamines, immune system responses and heart rate during the playing of Pachinko. The following significant results were observed. (1) Plasma concentration of beta-endorphin increased before playing Pachinko and while in the Pachinko-center (p<0.05). (2) Beta-endorphin and norepinephrine increased when the player began to win (i.e. at “Fever-start”) compared to baseline (p<0.05). (3) Beta-endorphin, norepinephrine and dopamine increased when the winning streak finished (i.e. at “Fever-end”) compared to baseline (p<0.05-0.01). (4) Norepinephrine increased past 30 minutes after “Fever-end” compared to baseline(p<0.05). (5) Heart rate increased before “Fever-start” compared to baseline, peaked at “Fever-start” and rapidly decreased to match rates measured at rest. But the increase was observed from 200 seconds after “Fever-start” (p<0.05-0.001). (6) There was a positive correlation between the number of hours subjects played Pachinko in a week and the differences between beta-endorphin levels at “Fever-start” and those at rest (p<0.05). (7) The number of T-cells decreased while the number of NK cells increased at “Fever-start” compared to baseline (p<.05). These results suggest that intracerebral substances such as beta-endorphin and dopamine are involved in the habit-forming behavior associated with Pachinko.

The relative contributions of genetic and environmental components in the variability of anthropometric measurements were studied in 54 twin pairs. Thirty pairs of monozygotic (MZ) and 24 pairs of dizygotic (DZ) twins were investigated to estimate the role of genetic, environmental and hereditary factors determining anthropometric measurements comprising body weight, standing height, sitting height, knee height, arm span, chest circumference and biiliac diameter. Within-pair variance for all the measurements were significantly smaller (p<0.05-0.01) in MZ twins than in DZ twins of both-sex twin group. Within-pair correlations for those measurements were higher (p<0.01) in both MZ and DZ twins. Correlation values were, apparently, higher more in MZ than in DZ twins. Besides, all the measurements are highly heritable components and heritability estimates ranged 40%-91%. When both MZ and DZ twin pairs of both-sex population were classified, based on age and sex, into different sub-groups interindividual variabilities were altered to a certain degrees. These data state that anthropometric measurements are influenced by genetic factors than environmental factors and besides, age and sex are possibly associated, to some extent, with the genetic influence upon anthropometric measurements.

Visual stimulation-reaction time and subsequent strike time in the sport of kendo were assessed using electromyographic (EMG) reaction time. Fourteen male college students (kendo athletes (n=7), non-kendo athletes (n=7)) were asked to perform a kendo strikes in response to visual stimulation from a flashing light signal. The strikes employed, the Hiki-Men (HM) and Hiki-Kote (HK), were performed using a bamboo sword, or Shinai, using both of the upper limbs as quickly as possible. The EMG signals from the right (R) and left (L) biceps brachii, the R-, and L-triceps brachii, and R-flexor carpi ulnaris muscles were recorded simultaneously together with the elbow joint angle and hitting shock signals. Total task time (TTT), pre-motor time (PMT), motor time (MT), and action time (AT) were measured for the HM and HK tasks. The photo stimulation body reaction time (BRT) was also measured. Significant strong positive correlations were observed between PMT and TTT for both HM and HK tasks (p<0.01, r=0.93-0.94). Multiple regression analysis was used to determine the contribution of each component of the model in TTT. The standardized partial regression coefficient (β) was significant (P<0.01) for MT (β=0.36-0.38), AT (β=0.49-0.56) and was highest for PMT (β=0.79-0.80). The individual time ratio for PMT, MT and AT to TTT was approximately 50%, 20% and 30%, respectively. No significant correlations were observed between BRT and TTT for the HM and HK tasks (r=-0.02, 0.16). These results suggest that PMT is the most important component contributing to the TTT, and that BRT is not correlated to the TTT in kendo strikes.

In this study, we conducted interviews three times after the Hanshin-Awaji Earthquake Disaster, investigated some problems due to the environmental changes over time after moving into the Temporary Housing, and examined some mental changes in the sufferers. In sofware, friendship was deepened only inside the Temporary Housing, but was separated from the surrounding neighborhood. In hardware, sufferers scarcely felt the facilities improved. With the lapse of time, these problems decreased, but only one problem, "difficulties of household economy", became worse. About the feeling of satisfaction, their dissatisfaction decreased in general. However, with regard to differences of age, the younger generation felt more dissatisfaction than the older generation.

The purpose of the study was to investigate the degree of subject variability in the peripheral and core temperature thresholds of the onset of shivering and sweating. Nine healthy young male subjects participated in three trials. In the first two trials, wearing only shorts, they were exposed to air temperatures of 5°C and 40°C until the onset of shivering and sweating, respectively. In the second experiment, subjects wore a water perfused suit that was perfused with 25°C water at a rate of 600 cc/min. They exercised on an ergometer at 50% of their maximum work rate for 10–15 min. At the onset of sweating, the exercise was terminated, and they remained seated until the onset of shivering, as reflected in oxygen uptake. In the first two trials, rectal temperature (Tre) was stable, despite displacements in skin temperature (Tsk), whereas in the third trial, Tsk (measured at four sites) was almost constant (30–32°C), and the thermoregulatory responses were initiated due to changes in Tre alone. The results of the first two trials established the peripheral interthreshold zone, whereas the results of the third trial established the core interthreshold zone. The results demonstrated individual variability in the peripheral and core interthreshold zones, a proportional correlation between both zones (r=0.87), and a relatively higher contribution of adiposity in both zones as compared with those of other non-thermal factors such as height, weight, body surface area, surface area-to mass ratio, and the maximum work load.

Anthropological research on children from Minsk was carried out within the framework of medical ecological monitoring. Besides the wide anthropometrical program, a study of the ecological conditions in the areas where the children examined reside and train was carried out. Comparison of the basic parameters of physical development in various age groups and the analysis of annual increases shows intensification of growth among modern children despite some decrease in the rates of acceleration. Some increase in body length and decrease of body weight as well as the reduction of chest circumference is common. Regional studies, particularly in the radiation control zones, show the dependence of physical development on the ecological situation.

The purpose of this paper is to analyze the current state of developmental researches in the area of psychophysiology of emotions in preschool and elementary school children. Electrodermal and cardiovascular activity measures are considered as the sources of indices of the autonomic nervous system activation during emotion-eliciting stimulation in children. We discuss the question of sensitivity of phasic and tonic autonomic measures for the identification of occurrence of emotion, mapping it along with valence and arousal dimensions in affective space, and to further differentiate emotions by their physiological manifestations. Considered are the conceptual and methodological issues related to psychophysiological measurements and developmental factors affecting the emotional reactivity in children. Special attention is devoted to the developmental aspects of psychophysiological studies on emotion such as the maturation of organs, integration of the autonomic and central nervous systems, age and gender-related changes in autonomic reactivity, and development of inhibitory control. Summarized are main findings relevant to psychophysiology of emotions in preschool and early school-age children and suggested are most perspective directions of their integration in the framework of modern theories of emotion.

In this study, tactile sensitivity of gloved hand in the cold operation has been investigated. The relations among physical properties of protective gloves and hand tactile sensitivity and cold protection were also analysed both objectively and subjectively. Subjects with various gloves participated in the experimental study during cold exposure at different ambient temperatures of -12°C and -25°C. Tactual performance was measured using an identification task with various sizes of objects over the percentage of misjudgment. Forearm, hand and finger skin temperatures were also recorded throughout. The experimental data were analysed using analysis of variance (ANOVA) model and the Tukey's multiple range test. The results obtained indicated that the tactual performance was affected both by gloves and by hands/fingers cooling. Effect of object size on the tactile discrimination was significant and the misjudgment increased when similar sizes of objects were identified, especially at -25°C.

The effects of paced breathing (PB) on the reproducibility of heart rate variability (HRV) measurements were examined in 55 male subjects (age range: 20–54 years). Spectral components of HRV were measured under a combination of two respiratory conditions (spontaneous and 4s PB) and two postures (standing and supine). The procedures were repeated 3 weeks after the first measurement. Log-transformed low-frequency (lnLF) and high-frequency (lnHF) components of HRV were calculated from a 205s electrocardiography (ECG) recording. The coefficients of interindividual variations of lnHF and lnLF (ca. 13–16%) and the intraindividual variations of the frequency components (5–6%) were not significantly affected by PB. The coefficients of intraindividual variation of heart rate, ln HF and ln LF did not correlate with age in either posture. Effect sizes of PB on the intraindividual variation ranged from −0.04 to 0.13. Although intraclass correlation coefficients (ICCs) were slightly improved by PB in some cases, the differences were negligible. The above results suggest that PB provides a limited improvement in the reproducibility of HRV measurements, and metronome-guided respiration is not necessarily required for HRV measurement if subjects are reminded to avoid irregular respiration.
