From 1995 to 2005 the information related to clothing and textiles publicized by 6 journals regarding Elder Women's body type was collected and analyzed. The results are as follows. 1. It has been investigated into the elder woman's body type since 1995, and this subject needs a detailed study. in audition, investigation into woman's body type has been studied parts of the body for clothing construction. 2. Analysis result for measure area preponderance(Seoul area and local metropolitan city) of area, measure subject number mainly to large scale group more than 300 people that measure is consisting most know can. 3. Where the way of measurement is concerned, there are direct measurements more than indirect measurements. In case of using just direct measurement, the study often mentions necessity of indirect measurements. Therefore it is thought simultaneous measurement is the most desirable. 4. A Body type characteristic of elder woman shows a size of every part diminishes as growing older. Owing mainly to obesity of waist and abdomen, they have a changed body a measure of around the abdomen is bigger than around the hips. hips drop and the upper half of the body down, and besides, feet are changed into the flat.

파장 할당에 대해 제안된 알고리즘들의 대부분은 무한한 수의 ADM을 가정하여 I/O 블로킹을 배제하였으며 파장을 할당한 이후, 네트워크 내에 파장이 불연속적인 형태로 남게 되어 링크 블로킹을 증가시킬 수 있다는 문제점이 있다. 또한 최악의 경우 O(W $N^3$)의 시간 복잡도를 갖는다. 본 논문에서는 온라인 상에서 동적인 트래픽 요청에 대해 최악의 경우 O(W $N^2$)의 복잡도를 가지면서 I/O 블로킹과 링크 블로킹을 모두 고려하는 파장 할당 알고리즘을 제안하였다. 파장의 불연속성을 최소화함으로써 블로킹의 발생을 감소시킬 수 있었다.

In this paper, the implementation of a new AF(Automatic Focusing) system for a digital still camera is introduced. The proposed system operates in real-time while adjusting focus after the measurement of distance to an object using a passive sensor, which is different from a typical method. In audition, measurement errors were minimized by using the data acquired empirically, and the optimal measuring time was obtained using EV(Exposure Value) which is calculated from CCD luminance signal. Moreover, this system adopted an auxiliary light source for focusing in absolute dark conditions, which is very hard for CCD image Processing. Since this is an open-loop system adjusting focus immediately after the distance measurement, it guarantees real-time operation. The performance of this new AF system was verified by comparing the focusing value curve obtained from AF experiment with the one from the measurement by MF(Manual-Focusing). In both case, edge detector was used for various objects and backgrounds.

Chemical mechanical polishing (CMP) of Ni was performed by the various ratios of four kinds of oxidizers and an addition of alumina powders as an abrasive in each slurry with the different oxidizers. Moreover, the interaction between the Ni and the each oxidizer was discussed by potentiodynamic polarization measurement, in order to compare the effects of Ni-CMP and electrochemical characteristics on the Ni with the different oxidizers. As an experimental result, the removal rate of Ni reached a maximum at 1 $vol\%$ of $H_2O_2$. Also the removal rates of Ni increased with the audition of alumina abrasives in each slurry. The potentiodynamic polarization of Ni under dynamic condition showed a significant difference in electrochemical behavior by addition of $H_2O_2$ in solutions. Ni showed the perfect passivation behavior in solution without $H_2O_2$ under potentiodynamic polarization condition, while active dissolution dominates in solution with the addition of $H_2O_2$. The results indicate that the surface chemistry and electrochemical characteristics of Ni play an important role in controlling the polishing behavior of Ni.

Jeung-Pyun Is a traditional fermented Korean food made with rice flour, water, sugar salt and unrefined rice wine(Tak-ju). In order to investigate how the addition of soybean and dextran have an influence on Jeung-Pyun fermentation and forming structure of Jeun-Pyun, adding soybean 20% and dextran 1%based on rice weight, we measured physicochemical properties. Also we measured dextran content of Jeung-Pyun batter according to the fermentation time and observed the inside of Jeung-Pyun by SEM in order to find out air pore condition. The dextran content of rice Jeung-Pyun and Jeung-Pyun adding soybean 20% was gradually increased as fermentation time was longer and Jeung-Pyun adding soybean 20% was higher than rice Jeung-Pyun. The specific volume of rice Jeung-Pyun and Jeung-Pyun adding soybean 20% was increased up to a fermentation time of 7~ 10 hours but it was decreased as fermentation time was longer. In the inside structure of Jeung-Pyun observed by SEM, the fermentation condition of Jeung-Pyun fermented for 3 and 7 hour was better and air pore size became larger, the number of it was decreased as fermentation time was longer. The air pore size of soybean 20% Jeung-Pyun is smaller more uniform than that of rice Jeung-Pyun. In conclusion. it can be suggested that the audition of soybean improves the quality of Jeung-Pyun and dextran has an influence on fermentation and forming structure of Jeung-Pyun.

본고는 천원 오천석의 민주주의 교육에 대한 현대적 의미를 제고한다. 특히 그의 후기 저서에 강조된 민족주의에 대한 논의 또한 요구되는 바이나 본고에서는 천원의 민주주의 교육이념 나타난 자유 개념을 분석하는 것으로 한정짓도록 한다. 이를 위하여 오늘날의 시대적 담론을 비판적으로 분석한 한병철의 논의를 바탕으로 천원의 민주주의의 의미와 평가를 논하고 그의 사상에 내재된 교육철학적 한계를 비판적으로 고찰한다. 이를 바탕으로 천원이 궁극적으로 지향하였던 도의적 민주주의 사상을 제고하여 오늘날 픽미세대에게 요구되는 자유 개념을 고찰하도록 한다.

This paper addresses uncertainty issues encountered recently in measuring head vibration using the conventional 6-axis or 9-axis bite-bar Those conventional bite-bars are shown to present insufficient information to measure a complete 6 degree-of-freedom motion of head vibration. In order to overcome such limit, a theoretical measurement model that consists of four 3-axis linear accelerometers is suggested (Theoretical backgrounds presented in this paper shall have been addressed in the international congress of ICA 2004 in this April). It is shown to enable the direct measurement of three angular acceleration components and six angular velocity-dependent nonlinear terms. In audition to the three linear acceleration terms, those nine angular motion-dependent ones are found to make it possible to evaluate the general head vibration for a given position. To examine the feasibility of the proposed method, a newly designed 12-axis bite-bar was developed. Detailed experimental results obtained using the developed 12-axis bite-bar are illustrated in the presentation of this paper, which illustrates what amount of measurement accuracy provides. But, this paper provides more detailed experimental data and extended uncertainty factors.
