This study presents the eigen ethnic function and mathematical processing method of human information. Human information can be definded as the overlap area taking the superposition property composed of intuition and sensory in stimulus/response (S/R) model, In S/R model, the intuition and sensory eigen ethnic function acts on the forming of perception. Perception process by the superposition property of intuition and sensory analogy to the basic neural network model. This analogy model extends to the analysis method. As an analysis method, optimal ratio number induced to the golden section ratio. Golden section ratio drived out by diverse source and implicated to the sensory and intuitive context such as beauty, harmony, optimality etc. This numerical orders can be applied to analysing the Perception process and extended to pursue the Potential human behavior, On the basic of proposed applying method, an illustrative mathematical examples are presented.

In this study, the experimental and analytical study were performed on the location of longitudinal cracks in the middle of underground box structures. The location where the longitudinal cracking occurred was investigated that the overlapping joint of the rebar and the section of maximum tensile stress generated. Using the finite element analysis, the strength reduction ratio of the rebar was estimated by lack of overlap joint length. As the result of adequacy investigation for the length of the overlap joint presented in the design criteria, it was analytically proved that the lack of the overlap joint length could be cause the decreasing cross-sectional force and concrete cracking. As the result of this study, the adequacy of the overlapping criterion in the current design criteria was confirmed based on the finite element analysis and actual field case. In the case of overlapping joints installed in inappropriate position, it was considered that a long term crack control would be need to ensure the sufficient safety factor for the designed cross-sectional force.

The purpose of this study is to develop a dress form for elderly women according to their somatotype to be used for improving the fit of garments and patterns. Analyzing each somatotype, there was a significant difference among the 4 somatotypes in most of measure items. Bend-forward Group had shorter front length items. Abdomen-fat Group had lower upper-body values than Average Group and similar lower-body values to Fat Group. In most items except height, Fat Group had the biggest values. Analyzing the mean cross-section according to the section measurement parts, no difference existed in shoulder part and under bust part. However, in upper bust, bust, waist, abdomen, high hip, and hip parts, a significant difference existed. Also, according to the results of the mean cross-section as well as the average cross overlap section for each somatotype, there was a significant difference among the four somatotypes. Thus, Abdomen-fat Group and Fat Group were similar, while Bend-forward Group and Average Group were alike. According to the increase of age, lower body tended to have more conspicuous changes. Analyzing the profile of somatotypes, there existed a obvious significant difference among the 4 somatotypes, implying that the characteristics of somatotype need to be reflected when to develop dress forms for elderly women. Therefore, these differences must be an essential factor in pattern design. Comparing the current dress form with the dress form developed with simulation, we could find that a dress form developed for elderly women which reflects the characteristics of body shape is much better than a dress form developed by simple size variation such as small, medium and large size divisions to improve the fit of garments and pattern designs.

This paper describes a corner matching technique for automatic relative orientation. Automatically matched corner points from stereo aerial images are used to a data set and help to improve automation of relative orientation process. A general corner matching process of overall image to image has very heavy operation and repetitive computation, so very time-consuming. But aerial stereo images are approximately seventy percent overlapped and little rotated. Based this hypothesis, we designed a sectional corner matching technique calculating correlation section by section between stereo images. Although the overlap information is not accurate, if we know it approximately, the matching process can be lighter. Since the size of aerial image is very large, corner extraction process is performed hierarchically by creating image pyramid, and corners extracted are refined at the higher level image. Extracted corners at the final step are matched section by section. Matched corners are filtered using positional information and their relation and distribution. Filtering process is applied over several steps because the thing affecting to get good result-good relative orientation parameter- is not the number of matched corner points but the accuracy of them. Filtered data is filtered one more during the process calculating relative orientation parameters. When the process is finished, we can get the well matched corner points and the refined Von-Gruber areas besides relative orientation parameters. This sectional corner matching technique is efficient by decreasing unnecessarily repetitive operations and contributes to improve automation for relative orientation.

Progressive familial intrahepatic cholestasis type 3 (PFIC3) is an autosomal recessive disorder of cholestasis of hepatocellular origin, typically seen in infancy or childhood caused by a defect in the ABCB4 located on chromosome 7. Here we report on an older patient, aged 15, who presented with biochemical testing that led to an initial consideration of a diagnosis of Wilson disease (WD) resulting in a delayed diagnosis of PFIC3. Diagnosis of PFIC3 was later confirmed by molecular studies that identified novel mutations in the ABCB4 gene. Cholestasis due to PFIC3 can cause elevated hepatic copper and increased urine copper excretion that overlap with current diagnostic criteria for WD. Molecular diagnostics are very useful for establishing the diagnosis of PFIC3. Ursodeoxycholic acid ameliorates cholestasis in PFIC3, and may help mediate a reduction in hepatic copper content in response to treatment.

A computer routine for personal computer(PC/AT class) is developed to analysize the mode characteristics of silica based optical waveguides whose cross sections are of semi circular and other typical shapes. The basic algorithm used in the routine is to convert the wave equation into a matrix equation by expanding the wave function in terms of simple harmonic functions. The matrix elements are a set of overlap integrals of sinusoidal funtions with appropriate weight given by the distribution of refractive index over the waveguide cross section. The eigenvectors and eigenvalues of the matrix is then computed via diagonalization. We explain some practical problems that arises when implementing the algorithm into the routine. By using this routine we analyze the mode characteristics of silica based optical waveguides of semi circular and some other typical cross sections.

The purpose of this study was to investigate the effect of physical properties and grain line of fabrics on the drape properties of the flare skirt. Horizontal section overlap map was obtained by three dimensional Moire Topography, It was concluded drapability of the skirt obtained by the map can be used to determine the ease of the skirt. Grain line such as bias and lengthwise direction showed the difference of quality of the drape at the hem line; skirt made by bias direction showed evenly distributed flare and effective for the aesthetic point view. No difference was observed between cotton and polyester fabrics probably due to the similar characteristics of the fabrics.

The dropper length calculation method about the normal same encumbrance spans is well known independent to whether the pre-sag is given or not. But, the dropper length calculation method for the elevating span which consists in the end area of a tensioning section and normally consists with overlaps is not well known. In this study, firstly, we investigate the dropper length calculation method about the elevating span whether the insulator is contained in or not, we also recognize the effect of dropper length due to the change of the take-off point. Secondly, we very this calculation method with a catenary sample data and check again with Gyeongbu HSL design data.

Today, in space design boundaries between spaces have become obscure and space images are changed and overlap each other. Moreover, with the digital technology creating more informational spaces with various interactions, the set up of intelligent space has been made possible in reality. As if to deny the law of physical limitation, interfaces are used as main concept in structuring and expressing the spaces. It appears once again when each section is an expressional factor of interfaces and when meanings are produced through the systemization. Here this study analyzes the hybrid action that appear in contemporary space design. At the very moment, interface emerged as an important concept, defining contemporary space design in a very different way and present interface as a new possibility in space.
