In a bathing environment, it is needed to evaluate an emotional effect quantitatively and continuously at stage of the product design for improving stress-relaxation effect. This study aimed to propose an index which can evaluate the comfort quantitatively and continuously on bathing. To search the physiological indices correlated to the comfortable feeling, we measured subjective evaluation of comfortable feeling in one-minute increments, with continuous measurement of physiological parameter before bathing, on bathing, after bathing. We analyzed the relationship between time-series data of the subjective evaluation and the physiological parameter. As a result, we proposed the evaluation index of comfortable feeling by using HF content obtained from spectral analysis of heart rate variability, and confirmed that the evaluation index can evaluate comfortable feeling quantitatively and continuously including the effect of personal preferences related to bathing.

The prevention of injuries during parasports is important for safety and to enjoy sports. However, in wheelchair rugby, there are few systematic studies on trauma precautions because of the differences in the physical function level of parasports athletes and the small number of players overall. We have proposed defensive motions to minimize injuries to the front and sides by analyzing videos of falls, a simulation using a multi-body model, and evaluating the injury to the head and upper limbs. By classifying the range of motion and muscular strength into three categories, the difference in disabilities was expressed using a multi-body model. The index, ULIC, was proposed to evaluate injuries to the upper limbs. It is calculated from the maximum moment value of the bones, using a simplified cylindrical model. The head injury criteria (HIC) and ULIC made it possible to evaluate the extent of injury by classification into one of four categories, depending on the presence or absence of injuries in the above regions. Furthermore, defensive actions not resulting in serious injuries and matching the difference between the degree of disability and fall, by predicting the potential injury to the head and upper limbs using the indexes, were proposed.

The automobile has an important impact on the daily lives of elderly people and their ability to participate in society. However, the deterioration of physical skills caused by aging is also a cause of vehicular accidents. In this paper, we conduct research into the cognitive function on driving ability, and propose a method to evaluate the driving ability of elderly drivers. The proposed system that the system is a computer simulator rather than an actual on-road driving experiment evaluates the ability to follow a road, the ability to avoid obstacles, and the ability to escape from unexpected dangers. To identify the operating characteristics and define an assessment index, 102 people over the age of 65 were surveyed on their driving attitudes. The investigation showed that the tasks and assessment index, and based on this system, another 92 elderly people participated in evaluation tests. The results showed there was a significant difference between elderly and younger drivers in terms of road-following and obstacle-avoidance ability. In addition, an assessment index with a five-level rating system, based on the characteristics of elderly drivers, was proposed.

船舶の機関室には火災探知器の設置が義務づけられているが、煙探知器においては、機関室内の気流の影響で探知器が有効に作動しない場合がある。発火源のほとんどが重油等の可燃性油であることから、本報では、探知器高さや気流影響を考慮して、重油燃焼時の煙探知器の作動特性を明らかにする。また、船舶の海上試運転時に実施される火災探知器の効力試験を想定し、重油燃焼の場合と同等と見なしうる発煙筒を用いた効力試験の方法についても述べる。

Control of thermal factors is needed to improve the conditions of occupants, because the thermal factors affect the conditions of occupants such as the comfort sensation, arousal level which is related to task performance. To determine the control method of thermal factors for improving the comfort sensation and the arousal level, indices which can evaluate the comfort sensation and the arousal level quantitatively and continuously are necessary. In this study, we focused on the physiological indices such as EEG (Electroencephalogram) which reflects the activity of central nervous system and ECG (Electrocardiogram) which reflects the activity of autonomic nervous system, and aimed to clarify the relations among the arousal level, thermal comfort and the parameters of EEG and ECG. We recorded the EEG, the ECG, the subjective feelings of thermal comfort and facial expression for evaluating arousal level of 14 healthy young males while they performed arithmetic tasks in environmental conditions that room temperature changed. From the results, among the parameters of EEG, there are indices that reflect the changes in arousal level only and other indices that reflect the changes in both arousal level and thermal comfort. On the other hand, among the parameters of ECG, there are indices that reflect the changes in both arousal level and thermal comfort.

It has been becoming general that an axial vibration damper is installed on the crankshaft of long-stroke diesel engines in order to minimize the axial excitation forces transferred to the hull through the thrust bearing. But the report that the axial excitation force increased at MCR in spite of the establishment of the damper has been occasionally presented, and besides the fact that peak to peak value (P-P) of the stress fluctuation at crank pin fillet increased in some cases as compared with P-P of the case without the damper has been confirmed as a result of full scale measurement. Therefore, the authors developed the new evaluation system for the vibration and the crank pin fillet stress of the crank shaftings with the axial vibration damper, and introduce the details in this report. In this system, the natural vibration and forced vibration are evaluated by means of a complex eigen value solution. The calculated results of the axial vibration response and crank pin fillet stresses have been compared with the measured ones, and the both show a fairly good agreement respectively.
