To identify the effect of the aroma foot spa on the stress, 12 university students with stress were divided into control group (6 subjects) and aroma foot spa group (6 subjects). Control group was not subjected to any kind of intervention while aroma foot spa group was subjected to 10 minutes of foot bath using 5% Juniper, lavender and lemon essential oil and 10 minutes of foot massage using massage cream during four weeks, two times per week. As for the evaluation method, brain wave was studied to measure the amount of change in stress. After measuring the change in the brain wave before and after the experiment, it was proven that the aroma foot spa group s Alpha wave (Z=-2.364, p<.05) and SMR wave (Z=-1.981, p<.05) were higher than those of the control group. Moreover, when the pre and post experiment results of the aroma foot spa group were measured, it was proven that the Theta wave (Z=-2.366, p<.05) decreased while Alpha wave (Z=-2.371, p<.05) increased. In other words, aroma foot spa that included foot bath using essential oil and foot massage increased Alpha wave which in turn influenced the brain wave due to increased blood circulation resulting from muscle relaxation. Moreover, SMR wave increase was closely related to the change in Alpha wave, which demonstrates that SMR wave increased due to stress alleviation. Accordingly, it may be possible to assume that aroma foot spa is effective in relieving stress.

In this study, the foot-spa driving circuit using ultrasonic vibrator was manufactured The used ultrasonic vibrator was PSN-PMN-PZT ceramic with the radius of $25{\Phi}$ and the thickness of 2, 2.5, 3, 3.5 and 4mm, respectively. Resonent frequency for driving ultrasonic vibrator at the fabricated circuit was generated using the self exciting and the external exciting methods. Fabricated foot-spa showed the best condition at the resonent frequency of 1.130MHz and the ceramic thickness of 2.0mm. That is, when the foot-spa was operated for 360 min. at $0.5\ell$ water, temperature increase of water was $14^{\circ}C$ at the self exciting method and $16^{\circ}C$ at the external exciting methods, respectively.

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.

This study selected a case study method conforming to qualitative research in order to analyzed how each type of fashion enterprises uses SNS in-side of fashion marketing based on content the researcher monitored and selected from the Facebook website for each enterprise. The standard to select fashion brands in this study is a graded list made based on ranking 5 analysis sites on social media (Socialbakers, socialDigm, Pulse K, BigFoot9, L2). The researcher sorted and then analyzed 2 brands that have many fan joiners and followers among fashion brands that were ranked top of the graded list, work in Facebook animatedly, and had representativeness in each type (SPA, Sports Brands). The study was conducted from January 2013 to March 2013, and the index of Facebook consisted of 3 kinds of elements (comment, like, and share). Each numerical value was counted to decide the monthly ranking. Content analysis was divided into public relations about brand, public relations about products, and customer participation and activities; consequently, the researcher investigated which content was post conforming to the ranking. The study analyzed the analysis results of each brand derived through the method of study compared to other brands. The results are as follows. In case of SPA brands, the category accounting for high rank in index analysis are public relation events to attract customer attention and products and offering information. The results of the monthly trend about whole post category were also similarly analyzed so the promotion goal that the brand wants to seek in priority coincides with the customer compliance rate. Next, in the case of sports brand, public relations for products offering information, event for arousing customer concern, and participation activities accounted for a high rank in the index analysis and posted the most in the analysis of the monthly trend for whole post category. The researcher came to understand that the direction of content for brands shown through Facebook coincides with customer sympathy.
