The usefulness of constitutional diagnoses based on skin measurements has been established in oriental medicine. According to Sasang constitutional medicine, humans can be distinguished based on properties of skin's friction, thickness and elasticity. To quantify and standardize skin diagnosis, the present study designed an equipment for measuring skin elasticity of hand. But there were some noises in measuring skin elasticity such as measurement method, environment, operator and conditions of patient. So we considered a six sigma project for reducing the measurement errors. The project was followed to discipline process of five macro phases: Define, Measure, Analyze, Improve and Control(DMAIC). So, we could find the major factors which should be controled for stabilizing measurement system and we revised the SOP(Standard Operating Procedure) of the skin elasticity measurement.

This study aims to analyze the process of three-year-old infants’ interactions with peers in the play process and form meaning for gifts through a qualitative approach. These studies may be the basis for knowing the process by which infants perceive the meaning of gifts. Therefore, based on the necessity and purpose of the study, what is the meaning of the present in the play of 3-year-old infant? The subjects of this study are 14 infants who are studying at Y kindergarten in Seocho-gu, Seoul. The research process consisted of play observation and in-depth interviews. As a result of the study, the meaning of gifts presented in the search for the meaning of gifts for infants through play observation was as follows. First, gifts for relationship building, second, gifts for self-satisfaction, third, gifts for Give & Take, fourth, conflicts over gifts, fifth, gifts for others. In addition, it was intended to embody the meaning of gifts for infants through in-depth interviews and conversations with infants by teachers. The consequences of this are as follows: First, gifts for special occasions, second, invisible gifts, and third, gifts for peers were found to be shared. This concept of gifts for infants aged 3 will provide meaningful implications for the concept of gifts for infants.

Pulse feeling is one of the most important diagnosis method in Oriental medicine. But it is not easy to make an objective and standardized diagnosis. In this study, we found how to quantify the pulse diagnosis. Specially the high practicality in clinic, we search some parameters especially well-related to floating and sinking pulse by statistical analysis. By extension, we find the pulse patterns of the floating and sinking pulse. We choose 15 subjects diagnosed as floating pulse and 15 subjects diagnosed as sinking pulse by oriental doctors. And their pulse signals were acquired by pulse analyzer which has piezoresistive pressure sensor. For the quantification of the floating and sinking pulse, at first, we examined the parameters which were highly correlated with oriental doctor's diagnosis. And then we derived pulse patterns of the floating-sinking pulse from preprocessed signal and its ensemble average. We also looked trend variation (PH-Curve) between contact and pulse pressure. As a result, statistically there is the biggest difference between contact pressure, the maximum pulse pressure, diastolic area (Ad) and floating and sinking data. Through the PH-Curve, which represented the relationship between contact and pulse pressure, we could divide the floating and sinking pulse clearly. As a basic research of pulse diagnosis algorithm, we can contribute to select essential parameters in diagnosis algorithm. And using these diagnosis method, we expect to find typical pulse patterns and some useful parameters about other pulses like slow/rapid, large/fine pulse and so on. We hope that this study will contribute pulse objectification.

Although the pulse diagnosis position, Guan is apart from Cun or Chi by only 10~20 ㎜ at most, traditional medical doctors applies different indent pressures and even they states different pulse images are felt at Cun, Guan and Chi. To support their clinical behaviors, in this study, we tested statistically whether there are differences in pulse waveform measured at these three positions with SphygmoCor system used world widely. A 30 years old female subject without any evidence of cardiovascular diseases was involved in this experiment. Radial pulse waves were recorded at three different positions on left lower arm 10 times at three positions - Cun, Guan and Chi. With ANOVA, we tested whether, among three different positions, there are any differences in 12 parameters of radial pulse waveform and in estimated AIx(Augmentation Index) as an arterial stiffness index extracted from radial pulse waveform. As results, differences in optimal indent pressure h0 were observed at different measuring positions (P < 0.001) but not significantly different. And pulse pressure h1s were found to be different (Chi < Cun < Guan). From these results, Oriental Medical doctors' diagnostic behavior of applying different indent pressures and their statements of plural pulse images can be asserted to be reasonable. On the other hand, estimated aortic AIx at Cun, Guan and Chi were 22.60 ± 3.06%, 18.60 ± 3.37% and 26.4 ± 5.02% respectively. Consequently, AIx at Gwan seems to be lowest and that at Chi seems to be highest. So, we assert the AIx at Chi is likely to be overestimated. In further studies, we want to examine what make differences in these parameters between measuring positions. And it also seems to be worthy to investigate the relationship between the depth of radial artery and AIx. And, ultimately, we need to determine the best measuring process including measuring position, hold-down pressure, signal quality validation and so on, so to achieve the optimal waveform which represents subject's health condition for both western medicine and traditional medicine

Pulse is one of the basic diagnostic information of TKM(Traditional Korean Medicine). To quantify and standardize pulse diagnosis, we had collected an amount of clinical data from May 2005 by using newly developed pulse analyzer. But there were many noises in pulse wave according to measuring method, environment, operator and condition of patient. So some data can't be included for analyzing pulse diagnosis. To reduce noises from measuring pulse and to collect reliable pulse wave data, we made the process map of measuring method and applied six sigma project. With this we can improved the method of measuring pulse wave in collecting clinical data. The project follows a disciplined process of five macro phases: define, measure, analyze, improve and control (DMAIC). A process map and C-E diagram are used to identify process input and output variables. The major input variables are selected by using C&E matrix, and process map is developed by analyzing input variables. And the optimum process conditions are going to be controled to avoid increasing loss of collecting pulse wave data.

Pulse diagnosis refers to the process of diagnosing a patient by feeling an artery on the wrist based on the shape that the pulse takes while the hold-down pressure increase. The styloid process artery on the wrist is usually felt, and the pulse is taken on Chon, Gwan and Check using three fingers. This study is to examine the structural difference in the location of pulse diagnosis by measuring and analyzing blood diameter, blood depth, and blood flow velocity of the location of pulse diagnosis by using ultrasonic wave (VOLUSION730 PRO, GE Medical, U.S.A). This study also attempted to grasp whether the characteristics of blood vessels differ depending on Body Mass Index (BMI) and analyzed their correlation with Oriental medical pulse diagnosis. The male subjects without cardiovascular diseases were divided into the normal BMI group, the underweight group and the overweight group and 10 people of each group were measured. Blood depth, blood diameter and blood flow velocity at the location of pulse diagnosis (Chon, Gwan, Check) of the wrists of left and right hands were measured and the pulse wave was measured by using pulse diagnosis instrument (3-D Mac, DaeyoMedi, Korea). The results of this study showed that the characteristics of blood vessels differ depending on the degrees of obesity, and the characteristics of floating pulse and sinking pulse of Oriental medical pulses were related to the degrees of obesity. This shows that the characteristics of the blood vessels of subjects and BMI information are the major indicators for diagnosis and are the matters that must always be considered when developing the algorithm of pulse diagnosis.
