The aim of this study is to analyze the research trend focusing on Yangseng(養生) studies in Korea. Through this study, the researchers attempt to explore the research trends of the Yangseng(養生) in Traditional Korean Medicine. Yangseng(養生) as a key word was searched on representative domestic databases of articles and the researchers and collected the articles of journals published from 1980 to 2012. Finally 350 articles of Yangseng(養生) were selected. After mid-2000s, Yangseng(養生) studies has been increased with the great interest in quality of life. Taoism and Traditional Korean Medicine were closely related with Yangseng(養生). Most of the Yangseng(養生) Studies in Medicine have been carried out by Traditional Korean Medicine and primarily focused in the literature. Yangseng(養生) has been defined as a sort of health-promoting behaviors. Therefore, Yangseng(養生) studies that mainly analyzed the variables associated with health-related quality of life and Yangseng(養生) and the main subjects were elderly and workers in this study. But every measuring instrument except Yangseng(養生) was adapted from western tools. In order to handle the new wave of society and medicine, new health concept and measuring instrument of Traditional Korean Medicine should be developed through Korean unique ideas of Yangseng(養生).

우리는 선행연구로 다기능 마찰력 측정기를 개발해 왔고 본 논문에서는 적응화 평활화 방법을 적용하여 마찰력 측정기의 성능을 개선하고자 하였으며, 스크래치 테스트를 통해 시편에 대한 마찰력과 마찰면의 모니터링 기능을 심도 있게 분석하였다. 일반적으로 강판을 가공하여 사용하고자 할 때 마찰을 줄이기 위해서 윤활유를 사용하지만, 윤활유는 환경오염의 큰 원인이기 때문에 본 연구에서는 윤활강판을 사용하였다. 특히, 윤활강판의 마찰계수는 유기, 무기 등의 시편의 종류 및 코팅층의 상태에 따라 변화하기 때문에 합금화 용융아연도금강판과 같은 다양한 시편에 대한 정밀한 실험을 통해 분석하였다. 이를 토대로 적응화 평활화법을 이용하여 잡음이 제거된 정확한 마찰계수를 측정할 수 있는 측정기의 성능을 향상시킬 수 있음을 검증하였다. 그 결과로서 마찰계수 0.16에 대하여 적응화 평활화법을 이용한 경우 저감률이 0.0417%임을 보였다.

울주군 대곡리 일대의 대곡천은 가지산 도립공원에서 양산단층을 가로질러 태화강 합류지점에 이르는 계곡과 암반이 발달된 지역이다. 계측할 반구대 암각화 암반은 광물학적 풍화, 절리, 하부의 세굴이나 공동이 확인되었다. 본 계측은 반구대 암각화가 세겨진 암반의 절리면을 대상으로 단기간 계측을 수행하였다. 기존 광섬유를 이용한 계측값(Ch4 150 ㎛)과 비교하여 비부착, 비접촉식 계측기는 300㎛의 변위값이 계측되었다. 향후, 시간대별 조도값에 적합한 HSV값의 적용과 다양한 계측경험이 누적될 경우, 본 계측기는 다양한 문화재에 활용이 가능할 것으로 판단된다.

Measurement is used for evaluation of product or process exactly. If it couldn't measured correctly, Quality-cost must be raised and it would be hard to improve product quality. So, this study suggests improvement guide line for the multilateral problems of measuring instrument operation based on the investigation of 157 small and medium-sized enterprises in February, 2008. To use inspection gig correctly, man who treat it must be accustomed with the structure, the performance, the method. The inspection gig is selected properly for the measurement goal. If not, results couldn't be correctly or wasted time, efforts, and costs. When selecting a inspection gig, the locating, the clamping, and the efficiency must be considered.

This research is the trial for the computation of the ease-rate for the bodice pattern. The result of the analysis about the cross section figures of garment space by using a 3-D measuring instrument is that: The garment space of each bodice by each body size is definite. In the figure of cross section of the basic lines, an area of cross section of garment space and length of cross section of garment space are not increased in proportion to an area of cross section of the body. The ease rate is the same no matter that flat-rate of the body is same or different. The ease-rate is computed by length of cross section of garment space that is in proportion to the radius of the body.

In general, a measuring instrument of sound noise use only one wired channel by one sensor. Therefor the measuring instrument use wired cables as the number of channels are provided by instrument. In a point of observed target it needs data from multiple sensors and In case of measured point is a large numbers the environment of constitution would be complicated because that is in need of channel and cable. So we need the method that can improve the existing transmission channel and cable environment even the measured point is increased. If we use the Code Division Multiple Access(CDMA) we transmit a large numbers of sensor data by using a common transmission channel. We present the method that transmits data of multiple sensor to wireless by using CDMA. This method can simplify the measurement environment dramatically when collecting data by using multiple sensor. We expect this study to contribute the part of multiple access technology and relation technologies on the measuring environment.

There is a need to enlarge the mother glass substrate in OLED to raise its productivity and to realize OLED TV. On the other hand, some difficulties may arise regarding the deflection of a large glass substrate during its handling operation due to its thinness $(0.5\sim0.7t)$, which is not even enough to allow it to stand its own mass. This thesis proposes a conceptual plan for the application of the clamping- and bending-end conditions to the glass substrate handler. To verify proposed plan, the non-contact 3 dimensional measuring instrument is developed. The composition of the 3 dimensional measuring instrument measures shape of the product using X-Y stage robot and laser distance sensor. X-Y stage robot and laser distance sensor are controlled by LabVIEW language. To calibrate measuring instrument, the direction conversion of the Euler angle was used. In order to confirm deflection of the glass substrate, the experiment was carried out at the bending end boundary condition and the proposed effect was verified.

Purpose: The purpose of this study is to analyze the depth according to curing using photocurable resin for dental three-dimensional printing. Methods: A stainless mold with a height of 4 mm was prepared. Ultraviolet (UV) polymerization resin was injected into the mold. Photocuring was then performed for 5 minutes using a photopolymerizer, and the height was measured using a digital measuring instrument (first group). Second, light polymerization was also performed outside the mold for 5 minutes, and the height was measured using a digital measuring instrument. Third, light polymerization was further performed for 5 minutes, and the height was measured using a digital measuring instrument. Statistical analysis was performed with the Kruskal-Wallis test, which is a nonparametric test (α=0.05). Results: The third group had the largest measurement length, whereas the first group had the smallest. However, the difference between groups was not statistically significant (p>0.05). The color of the first group was different from that of the second and third groups. Conclusion: All of the 4-mm-thick photocured specimens had a curing reaction, but the part that was not directly irradiated with UV did not show its original color.
