  • In this study, the deformation characteristics of atrtificially fractured joints of granite under normal and shear loading were investigated. To obtain the characteristics of joint deformation, compression and shear tests were performed in the laboratory on three different sizes of rock specimens. The rock used in the experimens was Iksan granite. Joints were produced artificially by fracturing using the apparatus for generating extension-joint. Joint normal deformability was studied by conducting cyclic loading tests on the joints. Joint closure varied non-linearly with normal stress through cyclic loadings. As normal stress increased, the joints gradually reached a state of maximum joint closure. The relation between normal stress and joint closure for mated and unmated joints was well described by the hyperbolic and exponential function, respectively. Joint shear deformability was studied by performing direct shear tests under normal stresses on the joints. it was shown that the behaviour in the prepeak range was non-linear and joint shear stiffness depended on the size of specimen and the normal stress.

  • The purpose of this study is to describe Eating Behavior for High school boys who are obesity using three factors(dietary restraint, disinhibition, hunger). The subjects were 200 high school boys. The convenience sample is consist of 101 normal weight boys and 99 obeses weight boys. Data were collected between Mat 1 and June 20 in 2000 and analyzed using the SAS package. The results are as follows: 1. The first hypothesis was not supported that is, the normal weight boys much more doing dietary restraint than the obese boys. 2. The second hypothesis was supported that is, the obese boys more experience disinhibition than the normal weight boys. 3. The third hypothesis was supported that is, the obese boys more experience hunger than the normal weight boys. The eating behavior of obese boys is different that of normal weight boys, The obese boys more experience disinhibition and hunger than the normal weight boys, but dietary restraint was more done the normal weight boys than the obese boys.

  • The present study was performed to investigate and discuss the aerodynamic characteristics of whispered and normal speech during reading paragraph tasks. 39 normal females(18-23 yrs.) read 'Autumn' paragraph with whispered and normal phonation. Their readings were recorded and analyzed by 'Running Speech' in Phonatory Aerodynamic System(PAS) instrument. As results, during whispered speech, the total duration was longer and the numbers of inspiration were more frequently shown than normal speech. The Peak expiratory and inspiratory rate were higher in normal speech, but the expiratory and inspiratory volume were higher in whispered speech. By correlation analysis, both whispered and normal speech showed significantly high correlation between total duration and expiratory/inspiratory airflow duration; numbers of inspiration and inspiratory airflow duration; expiratory and inspiratory volume. These results show that whispered speech needs more respiratory effort but shows poorer aerodynamic efficacy during phonation than normal speech.

  • In this paper we present a remeshing algorithm for irregular meshes with boundaries. The irregular meshes are approximated by regular meshes where the topological regularity is essential for the multiresolutional analysis of the given meshes. Normal meshes are utilized to reduce the necessary data size at each resolution level of the regularized meshes. The normal mesh uses one scalar value, i.e., normal offset value which is based on the regular rule of a uniform subdivision, while other remeshing schemes use one 3D vector at each vertex. Since the normal offset cannot be properly used for the boundaries of meshes, we use a combined subdivision scheme which resolves a problem of the proposed normal offset method at the boundaries. Finally, we show an example to see the effectiveness of the proposed scheme to reduce the data size of a mesh model.

  • This paper proposes a class of distributions which is useful in making inferences about the sum of values from a normal and a doubly truncated normal distribution. It is seen that the class is associated with the conditional distributions of truncated bivariate normal. The salient features of the class are mathematical tractability and strict inclusion of the normal and the skew-normal laws. Further it includes a shape parameter, to some extent, controls the index of skewness so that the class of distributions will prove useful in other contexts. Necessary theories involved in deriving the class of distributions are provided and some properties of the class are also studied.

  • Objectives Although tongue diagnosis is one of major diagnostic methods in east Asian traditional medicine, the standard of normal tongue color have not established. So we tried to suggest the method to establish the standard of normal tongue color range and the pilot data about the normal range. Materials and methods: 22 precedent study papers that presented the numerical data of normal (light red) tongue color were analyzed. At the same time, 46 adult people tongue color data were also collected and analyzed. Results Precedent studies showed remarkable fluctuations of the range of normal tongue color. Collected tongue color data of the 46 people showed mean Hue value 2 and standard deviation 14 in HSB system. Additionally, 3 ways of standard establishment for normal tongue color were suggested. Conclusion We suggest statistical method as a reasonable method for tongue color standard establishment and $2{\pm}14$ as a reference Hue value for normal tongue color.

  • Objective : This research was designed to study the characteristics of heart rate variability in postpartum women compared with normal women. Method : HRV data of postpartum women were gathered from 255 women who was hospitalized for oriental postpartum treatments(Age : 25-35). HRV data of comparison group were gathered from 327 women who visited hospital to check up their health(Age : 25-35). The SPSS 12.0 for windows was used to analyze the date and the independent samples t-test was used to verify the result. Result : 1. Mean-RR and SDNN of postpartum women group significantly decreased compared with that of normal women group. But, Heart Rate of postpartum women group significantly increased compared with that of normal women group. 2. HRV-Index, RMSSD and SDSD of postpartum women group significantly decreased compared with that of normal women group. pNN50 of postpartum women group significantly increased compared with that of normal women group. 3. Ln(TP), Ln(VLF), Ln(LF) and Ln(HF) of postpartum women group significantly increased compared with that of normal women group. 4. There were no significant differences in Normal LF, Normal HF and LF/DF Ratio between postpartum women group and normal women group. Conclusion : The result suggest that the function of heart of postpartum women group significantly decreased compared with that of normal women group. Futhermore although the ANS maintained the balance in the range of normality, the sympathetic nervous system frequently revitalized which caused increasing the heart of pulsation.

  • Purpose: This study examined whether or not the balance performing ability of the disabled (blindness and deafness) is lower than normal people. Chronometry was used to compare the balance maintaining ability of blind and deaf subjects with that of normal subjects under the same conditions. Methods: In this study, balance foam, eye bandage, earplugs and headphones were used. The balance foam used in this study is smooth with slight elasticity and a convex upper side, 60cm wide, 15cm long and 9cm high. The eye bandage was used to artificially block the sight of the normal subjects, and the earplugs and headphones to block their hearing. Results: The mean time of the normal subjects standing with their eyes open, blindfolded and wearing ear plugs was 26.7, 19.8 and 28.7sec, respectively. The mean standing maintaining time for the blind and deaf subjects was 12.5 sec and 24.1 sec, respectively. The t-test result of the calculated mean time showed no significant difference (p>0.05) between the normal subjects and the normal subjects with their hearing blocked but there was a significant difference between the normal subjects with their hearing blocked and the deaf subjects (p>0.05). Conclusion: There was significance between the normal subjects and the normal subjects with their eyes blocked but there was no significant difference between the normal subjects with their eyes blocked and the blind subjects. Furthermore, there was a significant difference between the deaf and the normal subjects, which corresponds to the report showing that sight has a significant influence on balance.
