The objectives of this study were to investigate the progress of obesity in women from childhood to adulthood and to analyze the characteristics of obese figures through comparing their body proportions to normal-weight people, to provide a basic reference for development of new size categories and improved pattern grading. Body measurement was made on 6,704 women age between 7-39 in Sizekorea 2004 database. The age range was divided into three groups: children(7-12), teenagers(13-18) and adults(19-39). The result of research into the characteristics of body proportions of obese figures and the classification of different figure groups of obese people are as follows: The ratio between width and circumference for each part of the body was investigated according to body weight which was grouped into three different weights of low, normal and obese body weights. And the result demonstrated that in all the ranges of age, the obese groups had the lowest ratio between width and circumference, having a thick body shape. And according to the result of comparing the ratio of the circumference of each body part divided by the waist circumference, the obese group also showed a low ratio, indicating that they have bigger waist circumference than any other body parts. By analyzing the ratio of circumference of body parts divided by waist circumference, three factors were identified as contributing to obesity. Using the factor loadings of the upper, distal and lower body obesity, a cluster analysis was carried out and three different categories of obesity were defined; abdominal obesity, distal obesity and proximal obesity.

The purpose of this study was to develop a plausible methodology based on experimental data how to set up darts and split lines on 3D parametric body dressed with tight-fit garment. The results were as following: Through the process of making convex hull, the concave parts were straightened to make a convex hull, especially in the center part of bust, under breast part and scapular part. To figure out the optimum positions of darts and split lines, the inflection points of curve ratio were searched along the horizontal polylines of waist and bust. This procedures produced reliable results with low deviation. Using Rapidform, CATIA and Unigraphics, six patches of bodice patterns were drawn and aligned. Paired t-test results showed the outline and area between 3D surface and 2D were not significantly different, meaning this method could be adaptable when flattening 3D surfaces. The amount of waist dart measured on the pattern showed that the highest portion was allocated on 2nd dart(back), followed by 1st dart(back), 1st dart(front), 2nd dart(front)/side dart, and center back dart. A series of findings suggested that curve ration inflection point could be used as a guide to set up darts and split line on 3D parametric model with low deviation.

Korea's seas have the potentials of dispute against China or Japan due to the overlap of the territorial waters and EEZ. In case of marine accidents, the nature of the sea tends to eliminate much of the track, making it another hardship in evidence adoption in case of an international dispute along with the false entries of fishing vessels' journals. Marine Digital Forensics protects the functions of computers and IT appliance on vessels and extracts evidence of voyage and accidents to resolve international dispute. The digital evidence, if tampered with its integrity, may lead to the rejection to a critical claim or may even fail to make a case. As a solution, this thesis suggests Marine Digital Forensics as a way to extract evidence and prove a claim. This may be utilized as means of scientific investigation on sea as overseas exchange increases and the vessels digitalize, leading to a solution in international disputes that may occur in the future.

Recently, it is possible to high speed transmission of the non-voiced data, including voice, data, moving image instead of voice only in the past by changing the communication method to digital form from analog owing to the development of semiconductor and computer technology which for information transmission of the remote point. By doing so, we can get the improvement of the noise effect and low cost but the loss of transmission bandwidth. It is necessary to take some method in oreder to reducing the fading which is propotional to transmission bandwidth during the transmission of radio communication channel, especially. When we design the digital communication system, we must considered to the fading effect in order to determination of the transmitting power, modulation /demodulation method, transmission speed, bit error rate. This paper mainly concerns to the method to the channel simulator which descrives the fading effect during the transmission by computer model and digital filter modeling of the radio fading channel by unsing the transmitting and received signal. By taking the inverse of the characteristic of the modeled filter, it is possible to improvement of the communication system by reducing the distortion and inter-symbol interference which occurs in the channel.

The recognition of a relatively big and rarely movable object. such as refrigerator and air conditioner, etc. is necessary because these objects can be crucial global stable features of Simultaneous Localization and Map building(SLAM) in the indoor environment. In this paper. we propose a novel method to recognize these big objects using a sequence of 3D scenes. The particles representing an object to be recognized are scattered to the environment and then the probability of each particles is calculated by the matching test with 3D lines of the environment. Based on the probability and degree of convergence of particles, we can recognize the object in the environment and the pose of object is also estimated. The experimental results show the feasibility of incremental object recognition based on particle filtering and the application to SLAM

In this paper, we propose a new automatic fingerprint identification system that identifies individuals in large databases. The algorithm consists of three steps: preprocessing, classification, and matching, in the classification, we present a new classification technique based on the statistical approach for directional image distribution. In matching, we also describe improved minutiae candidate pair extraction algorithm that is faster and more accurate than existing algorithm. In matching stage, we extract fingerprint minutiaes from its thinned image for accuracy, and introduce matching process using minutiae linking information. Introduction of linking information into the minutiae matching process is a simple but accurate way, which solves the problem of reference minutiae pair selection in comparison stage of two fingerprints quickly. This algorithm is invariant to translation and rotation of fingerprint. The proposed system was tested on 1000 fingerprint images from the semiconductor chip style scanner. Experimental results reveal false acceptance rate is decreased and genuine acceptance rate is increased than existing method.
