Since the introduction of a new field of skin care to Korean market which was developed in 1980, a variety of skin care therapies have appeared in mid-1990s. Therefore, in particular, it is considered that aroma therapy is one of the most preferred methods for skin care. Therefore, previous studies focused just on clinical effects of aromatherapy while this study focuses on aestheticians by identifying whether performance of aromatherapy, and their contribution to income will influence on satisfaction in aestheticians and customers' intention to reuse aromatherapy service for positive demonstration. The results of the study are presented as follows: First, it is demonstrated that side-effect of aromatherapy, contribution to income, and customer satisfaction have significant effect on professional aestheticians. In particular, in respect to the aestheticians, this study obtains the results rather different from the estimation that customers are satisfied with the professional service though they have side-effect. Second, as the satisfaction in professional aestheticians after skin care service is a significant factor that influences on intention to reuse it, this study concludes that re-management on behaviors is required according to the degrees of satisfaction.

In this work, a smart skin of multi-layer structure is designed and manufactured. Through the compression test, the characteristic of smart skin behavior was examined. We have predicted stress of each layer and the first failed layer of the smart skin structure by using MSC/NASTRAN. The finite element model was verified by comparing measured data from the compression test and result from the geometrically linear/non-linear analysis. The finite element model was used for obtaining design data from the parametric study. It was confirmed that shear moduli of honeycomb core affect the buckling load of smart skin where shear deformation was considerable.

The skin friction of a pile foundation is important and essential for its design and analysis. More attention has been given to the softening behaviour of skin friction of a pile. In this study, to investigate the load-transfer mechanism in such a case, an analytical solution using a nonlinear softening model was derived. Subsequently, a load test on the pile was performed to verify the newly developed analytical solution. The comparison between the analytical solution and test results showed a good agreement in terms of the axial force of the pile and the stress-strain relationship of the pile-soil interface. The softening behaviour of the skin friction can be simulated well when the pile is subjected to large loads; however, such behaviour is generally ignored by most existing analytical solutions. Finally, the effects of the initial shear modulus and the ratio of the residual skin friction to peak skin friction on the load-settlement curve of a pile were investigated by a parametric analysis.

This paper describes a novel experiment that measures skin movement with respect to the flexional motion of a hand. The study was based on MR images in conjunction with CAD techniques. The MR images of the hand were captured in 3 different postures with surface markers. The surface markers attached to the skin where employed to trace skin movement during the flexional motion of the hand. After reconstructing 3D isosurfaces from the segmented MR images, the global registration was applied to the 3D models based on the particular bone shape of different postures. Skin movement was interpreted by measuring the centers of the surface markers in the registered models.

The purpose of this study was to investigate the relationship between women's face satisfaction and makeup satisfaction, to disclose the differences of makeup satisfaction according to demographic variables, and to examine how makeup satisfaction was influenced by face satisfaction and demographic variables. The subjects were 200 women over age 17 living in Seoul and its peripheral areas. The results of this study were as follows: Face satisfaction were drawn three factors. Factor 1 was face contour satisfaction, Factor 2 was skin satisfaction, and Factor 3 was lips and eyes satisfaction. There were significant positive relationship between factors of face satisfaction and makeup satisfaction. Also, the face contour satisfaction was in positive correlation with satisfaction of features, and the skin satisfaction was in positive correlation with that of features. There were significant positive correlations between makeup satisfaction and face shape, eyes, nose, lips, chin, and cheek bone satisfaction. Face satisfaction didn't show significant difference according to demographic variables, but makeup satisfaction showed significant difference according to age and occupation. Face satisfaction was influenced by the facial face, clarity of skin, elasticity of skin, skin color, and ages. The explanatory power of the 4 variables were 24.5%. Makeup satisfaction was influenced by lips and eyes satisfaction, ages, and skin care level. The explanatory power of the 3 variables were 13.3%.

Purpose: The aim of the study was to identify the effects of aroma-foot-reflexology on premenstrual syndrome, dysmenorrhea and lower abdominal skin temperature of nursing students. Methods: This study used a pretest-posttest quasi-experimental study design. The participants were divided into two groups, a control group with 37 students and a treatment with 24 students. A 35 minute three times a week aroma-foot-reflexology was carried out for the treatment group. The data were analyzed using SPSS/WIN 17.0 program. Results: The results showed that aroma-foot reflexology was significantly effective in reducing premenstrual syndrome and dysmenorrhea, and raised lower abdominal skin temperature of the students. Conclusion: The results of this study indicated that aroma-foot-reflexology is an effective nursing intervention in reducing premenstrual syndrome and dysmenorrhea and in improving lower abdominal skin temperature. It is, therefore, recommended that the aroma-foot reflexology should be a clinical practice as an effective nursing intervention to reduce premenstrual syndrome and dysmenorrhea and to improve lower abdominal skin temperature of nursing students.

The method of measuring skin active points is a technique for obtaining a lot of biometric information because it is measured with convenience, low cost and non-invasive methods. In this paper, we used in a three electrode measure method that has the advantage of measuring the impedance of the APs under the skin. The impedance measuring method is well illustrated by a simple model of an equivalent electrical circuit that correlates well with experimental results. The characteristic frequencies of APs are about 15-30HZ higher than that of surrounding skin and the values of measured reactance are about 35-77KΩ smaller. This technology analyzed accurately and objectively the reactance and characteristic frequency of APs and the surrounding skin using a non-invasive measuring system.

Objectives: The objective of this study was to investigate the effects of smoking on the skin bio-electrical capacitance at twelve source points. Methods: Twenty healthy male subjects were assigned to smoking and sham-smoking by a random cross-over design. Skin bio-electrical capacitance was measured at twelve source points for 10 minutes before and after smoking. The change of skin bio-electrical capacitance was analysed. Results: 1. The skin bio-electrical capacitance at LU9, PC7 and LR3 was significantly increased after smoking. 2. In the smoking group, the skin bio-electrical capacitance at the source points of Hand Yin meridians significantly increased compared to that of Foot Yin and Hand Yang meridians. Conclusions: Smoking significantly increased the skin bio-electrical capacitance at the source points of Lung, Pericardium and Liver meridians. Hand Yin meridians appear to be more vulnerable to smoking than other meridians.

Based on the equivalence principles of physical properties, geometric properties and externally applied forces between a surface and the corresponding curves, we present a fast physics and example based skin deformation method for character animation in this paper. The main idea is to represent the skin surface and its deformations with a group of curves whose computation incurs much less computing overheads than the direct surface-based approach. The geometric and physical properties together with externally applied forces of the curves are determined from those of the surface defined by these curves according to the equivalence principles between the surface and the curves. This ensures the curve-based approach is equivalent to the original problem. A fourth order ordinary differential equation is introduced to describe the deformations of the curves between two example skin shapes which relates geometric and physical properties and externally applied forces to shape changes of the curves. The skin deformation is determined from these deformed curves. Several examples are given in this paper to demonstrate the application of the method.

Objective: This study was conducted to investigate the effect of active movement with skin mobilization on range of motion, pain, and rating of perceived exertion in patients diagnosed with axillary web syndrome after axillary lymph node dissection. Design: A Case report Methods: It was performed on 7 patients diagnosed with axillary web syndrome after lymph node dissection. The subjects experienced a decrease in the range of joint motion and pain in movement when raising their arms in their daily lives, and complained of discomfort. The active range of motion, numeric rating scale, and modified Borg scale of shoulder joint flexion were measured, and the differences after active movement with skin mobilization were compared. Results: All subjects increased by 24.9 degree on average in active range of motion after active movement with skin mobilization intervention. There was no pain in the maximum range of joint motion measured before intervention, and rating of perceived exertion was significantly reduced. Conclusions: Active movement with skin mobilization can be a very useful way to help improve and treat axillary web syndrome, and it is recommended for improving the function and quality of life of axillary web syndrome patients. and It is also believed that it can be used steadily at home through the education of patients and families.
