Generally, we take a bath to obtain a clean body as well as a good health. Human body generates various physical and emotional changes by stimulations of therapeutic effect of heat and hydraulic pressures. Accordingly, we can obtain not only relaxations but also effects of hydrotherapy. The survey of bathing/showering behaviors and therapeutic effect of heat reactions present elementary data for development of a bathing/showering system. However, there are few existing data for bathing/showering behaviors and effects. Consequently, surveys were performed to know patterns of bathing and showering, and relations between physiological changes and water temperature were examined by partial bathing on human body in this study.

This paper proposes healthcare bathing system for improving the multisensory function and not washing. We designed various types of bathtub for developing bathing system. This system consists of whirlpool bathtub for multisensory stimulation, a cover of bathtub with visual-auditory stimulation function, a small size PC for main control, touch panel, digital multimedia broadcasting (DMB), color-changeable LED mood lighting system for improving visual sensibility and speaker. We investigate the effects on autonomic nervous system during bathing with healthcare bathing system for improving the multisensory functions. To analysis physiological parameter, body temperature, blood pressure, intraocular pressure and heart rate variability (HRV) were measured before, during and after bath using healthcare bathing system. Experiments were performed on partial immersion bath and the water temperature was kept $39{\pm}0.5^{\circ}C$. The body temperature and the heart rate variability of the subject were measured every 5 minutes before, during, and after the bath. In analysis of HRV, the parasympathetic nerve increased from starting bath and decreased after 15 minutes. So the subjects felt comfortable at 15 minutes after starting bath. Blood pressure decreased to 16mmHg maximumly however pulse increased. Bath using healthcare bathing system for improving the multisensory functions affects positively the circulation of the blood. From this results, it leaves something to be desired in evaluation of serviceability and physiological analysis using the healthcare bathing system, however, we expect to analyze more clearly the relationship between the serviceability of product, physiological change and sensibility by various physiological parameters.

As same time of starting on the Korean Long-term Care Insurance System, the government developed a program to train new qualification of long-term care workers. The number of enrolled long-term care workers are 950,000 persons in 2010. Mostly they are working in home based care work places such as home visit care centers and home visit bathing centers covered insurance. The purpose of this study is to understand the difference of task performance requirement according to long-term care workers' responsibilities which divided into home visiting care and home visiting bathing. The comparison analysis was conducted to task performance requirement in basic management, safety management, administration management, practical services. Key result was found that task performance requirement of long-term care workers whose responsibilities are home visiting care were more higher than the home visiting bathing. Finally, To improve quality of home visiting care and home visiting bathing, it is necessary to provide the fields based continuing education and reflect new reimburse system.

Purposes: We studied whether forest bathing is effective in improving the stress of the human body. Therefore, we investigated changes in pulse rate, stress index, and autonomic nervous system after 2 hours of forest bathing on Jeju Samdasu Forest Methods : The study was conducted before and after forest bathing through heart rate variability and questionnaire. Results: After forest bathing, the average pulse rate of the experimental group was significantly increased. The stress index significantly decreased in the post-test in the experimental group. The cumulative stress, sympathetic activity (LF), parasympathetic activity (HF) change, and LF/HF ratio were slightly different from those of post-test in the experimental group, but were not statistically significant. In the survey of job stress average index and state characteristic anxiety index through questionnaire, it decreased significantly after forest bathing (p<.001). Conclusions: The Samdasu forest bathing has been proven effective in enhancing pulse and reducing stress, so it is evaluated that forest bathing is effective in promoting health.

Purpose: In this study changes were observed in body temperature, heart rate and arterial oxygen saturation (SaO2) of newborns after bathing and to determine the effects of covering their heads with cotton hats after bathing. Methods: Participants were 58 newborn infants, 31 in the experimental group had their heads covered with cotton hats after their bath while 27 in the control group did not. Body temperature, arterial oxygen saturation and heart rate were measured at 8 consecutive times after bathing. Data were analyzed using t-test and repeated measures ANOVA. Results: Body temperature declined shortly after bathing. The experimental group showed faster recovery (p<.001). Heart rate increased after bathing in both groups. Heart rate in the experimental group decreased for 120 minutes and gradually increased to baseline (p<.001). In the control group, heart rate decreased for 180 minutes and then increased but did not reach the baseline (p<.001). Arterial oxygen saturation decreased shortly after bathing and recovery to the baseline was more rapid in the experimental group (30 minutes vs. 60 minutes) (p<.001). Conclusion: With significant changes observed in newborns' body temperature, arterial oxygen saturation and heart rate, covering the head right after bathing is effective in stabilizing infants' physiological system.

We investigated the activities of autonomic nervous system during foot bathing. The effect of foot bathing was evaluated for four subjects by observing the characteristic of heart rate variability and bodily temperatures. The foot bathing was done with a commercial foot spa (Duches Co.) utilizing the four functional modes of the spa for two different temperatures of $35^{\circ}C\;and\;40^{\circ}C$. The four functional modes were clam, vibration, air bubbles, and both vibration and air bubbles. The experimental results showed that the temperature of foot and that of face right after foot bathing were not that different from each other. But, for heart rate variability, the activation of parasympathetic nerve showed distinctive increase at $40^{\circ}C$ of water temperature. In the analysis of heart rate variability for different functional modes, the change was not distinctive for different modes at $35^{\circ}$ of water temperature. However, at $40^{\circ}C$, the activation of sympathetic nerve showed distinctive increases with the increase in the complexity of functional modes.

The purpose of this study was to investigate the human body effect according to micro bubble and LED lighting in half body bathing. This study was conducted on 6 elderly male and 7 female in 70's, and the subjects were classified into half body bathing with the micro bubble group (3 male, 4 female) and without the micro bubble group (3 male, 3 female) to proceed to the experiment. Experiments were performed 4 times by changing the LED lighting colors. As a result, parasympathetic nerves were activated than sympathetic nerves (micro bubble stimulation : 21.41%) and the temperature of the body were increased by $5.93^{\circ}C$ with micro bubble and red lighting stimulation. It is considered that this work will help to utilize the half body bathing system for the micro bubble and LED lighting.

This article is written on the ground that one of the major characteristics of Chinese New Period women's novels is about family dissolution and calling and it is examined based on analysis of "The Bathing Woman" by Tie Ning. In "The Bathing Woman", the family seems 'Regular' externally but it is actually fragmented internally. The author offers patriarchal perspective on 'Family' from the eyes of daughter of the family. The problems are classified into three categories. First, it is the problem of exclusiveness embedded in the essential characteristic of family represented by blood relation. Second, it is the research on the reason for family dissolution. Tie Ning finds the reason at 'Unmotherly mother, that is the lack of maternal instinct. Third, it is the expectation of the restoration of dissolved family. Tie Ning's indication of 'Family' is equal to 'Mother' and 'Mother' is the source and power that can heal and restore the dissolved family in her novel. It is expansion of maternal instinct represented by protection and caring into 'Practical action' and it is meaningful in a way that it expands the principle of maternal instinct and sublimates it into universal morality. However, it should not be overlooked that it could be another moral system that could suppress the females in other ways.

Analysis of behavior pattern and thermal response during bathing and showering provides important fundamental data when developing an automatic bathing/showering system. The behavior pattern and physiological changes during bathing/showering were measured und analyzed for the aged male group. We recorded the volunteers showering at front, back, left and right view using four CCTV cameras in order to study the behavior pattern during showering. The photographic data were analyzed by counting the frequencies of body contact and identifying zones where hands could reach. In order to study the thermal response, we measured the blood pressure (B.P), heart rate (H.R), body temperature (B.T.), breathing rate (B.R) for the different water temperatures and the locations of immersion for the young and old age groups. The results showed that the frequencies of body contacts were varied for different body sections. Also there were some body sections where hands could not be reached because of reduced pliability and muscular strength of the aged group. But we observed rather uniform body contact frequencies when a towel was used. In partial immersion bath experiments, we observed the changes of B.P. H.R and B.T in the case of young and old age groups, and the changes were more significant in the young age group.
