이영섭,윤동진,정중채 한국비파괴검사학회 2003 한국비파괴검사학회지 Vol.23 No.3

지하매설 상수도 배관의 누수는 사회적, 환경적 그리고 경제적 문제를 야기시킨다. 이러한 누수에 대한 적절한 대응책의 하나로서 배관의 누수지점에 대한 탐지 및 수리가 해당될 것이다. 누수음은 배관의 누수지점의 식별에 좋은 탐지원이다. 비록 청음봉, 층음기 또는 지상마이크로폰과 같은 누수음으로 누수지점을 탐지하는 몇가지의 방법이 있어 왔지만, 그들은 그렇게 효율적인 도구들은 아니었다. 본 논문에서는, 좀 더 쉽고 효율적인 방법을 제공할수도 있는 음향방출센서와 가속도계를 사용한 누수위치탐지를 다룬다. 누수지점 탐지를 위해 센서로 부터의 입력신호에 대한 필터링, 신호처리 및 알고리듬을 기술하였다. 120 미터 길이의 배관이 실험을 위해 설치가 되었고, 실험결과들은 음향방출센서와 가속도계가 누수지점의 정밀탐지에 이용될 수 있음을 보여 주었다. 누수지점의 탐지에 극히 중요한 지하매설배관 속의 유체의 음파 전파속도에 관한 이론적 해석 또한 기술되었다. Leaks in underground pipelines can cause social, environmental and economical problems. One of relevant countermeasures against leaks is to find and repair of leak points of the pipes. Leak noise is a good source to identify the location of leak points of the pipelines. Although there have been several methods to detect the leak location with leak noise, such as listening rods, hydrophones or ground microphones, they have not been so efficient tools. In this paper, acoustic emission(AE) sensors and accelermeters are used to detect leak locations which could provide an easier and more efficient method. Filtering, signal processing and algorithm of raw input data from sensors for the detection of leak location are described. A 120 m-long pipeline system for experiment is installed and the results with the system show that the algorithm with the AE sensors and accelerometers offers accurate pinpointing of leaks. Theoretical analysis of sound wave propagation speed of water in underground pipes, which is critically important in leak locating, is also described.

By now, the actual situation of the sports of Koryo Ages and it's summaries are follow. (1) Koryo Ages was the middle ages of Korea and connected the Lee Dynasty to the Unified silla. Though Koryo had various hard such as the Military Upheval, foreign imvades and more, it could be said to keep the nation without losing the national identity. (2) To the social characterstics of Koryo Ages, the Literal-First-Military-Second trend such as the abrogation of military test, the carrying out of national events such as the Lotus Light Festival and the Eight Relationship Festival, and the prevalence of public entertainments could be listed. And almost public events were concentrated on national holidays such as the Seol, the First full moon day, the Eano, the Yudu, the Chusok, and the Winter solstice. (3) Sports of Koryo Ages could be classified in 3 of military arts, games, and entertainments. In case of military arts. the classical one was succeeded, however, Soo Jun and Arts on Horse were estimated to be created in Koryo Ages. To see the recommended sports in Koryo Ages, many games similar to the sports of modern viewpoints were founded. The one of represented was Gyeokgu. Gyeokgu had the properties such as the securing of a field, the diversity of game skills the use of a stick or a bow, and the attracting of an audience and was never considered to be inferior to the other sports events of modern and more, there was the traditional game, Soo Bak Hee. The entertainments that had been favored in Koryo ages were Hawk hunting, Too Ho, and Seok Jon Hee, the tactic ones and other general ones: almost traditional ones were considered to be formed during that period (4) In the study on th sports activity of Koryo Ages, the limit was felt was that the historical data concerned were too weak. In future, further systematic study related to sociology, folklore, and pedagogy was seemed to be needed.

정인식,김호운,김진섭,이정희,이종현,신장규,박세일,권성원 경북대학교 센서기술연구소 1998 센서技術學術大會論文集 Vol.9 No.1

A planar chromel-alumel multijunction ac-dc converter was fabricated on a LPCVD Si_(3)N_(4)/SiO_(2)/Si_(3)N_(4)-diaphragm, prepared by silicon bulk micromachining, which thermally isolated a bifilar evanohm-heater and the hot junctions of a chromel-alumel thermopile from the silicon substrate. The voltage responsivity, the ac-dc transfer error, and the fluctuation of the output thermoelectric voltage of the converter were investigated. The respective voltage responsivities in air and in a vacuum of the converter were about 3.16 mV/mW and 9.41 mV/mW. The ac-dc voltage and the current transfer errors in air were about ±1.5 ppm and ±0.7 ppm in a frequency range from 10 Hz to 10 kHz, respectively. The fluctuation of the output thermoelectric voltage from 5 seconds to 120 seconds after preheating in air for 5 seconds was about 0.06 % for a heater input of dc 1 V.

A planar Bi-Sb multijunction thermal converter for the precise measurements of ac voltage and current has been fabricated and its characteristics was discussed. In order to convert ac power into heat, a bifilar thin film Pt-heater, which could cancel its Thomson and Peltier effects, was prepared on the Si_(3)N_(4)/SiO_(2)/Si_(3)N_(4) diaphragm for the thermal isolation between heater and silicon substrate. To convert the temperature or the heat generated by the heater into dc voltage and current, hot and cold junctions of the Bi-Sb thermopile, which has a large difference in Seebeck coefficients, were formed on the dielectric diaphragm and the silicon substrate, respectively. The respective thermal sensitivity of the thermal converter with a bifilar heater was about 10.1 mV/mW and 14.8 mV/mW in the air and vacuum, which is about eight times higher than that of commercial 3-dimensional thermal converter. In the case of ac 2 V-input voltage, the ac-dc voltage transfer difference was about ±2.0 ppm, and in the case of ac 10 mA-input current, the ac-dc current transfer difference was about ± 0.6 ppm, in the frequency range from 10 Hz to 10 kHz.

우리 영동대학교에서 1998년 이후 지금까지 진행하여 온 특별 주제 학습과정인 STC(Special Topics COurse)프로그램을 기존의 운영틀에서 탈피하여 한층 더 발전시킨 복합STC로 활용하고자 하였으며, 특히 이를 졸업생의 취업 및 진학의 방법으로 최대한 활용하고자 계획·운영하였다. 그 결과 취업 및 진학과 같은 진로 확립은 물론 전공지식의 확대, 자격시험 대비능력의 향상, 학생과 교수간의 유대강화 등과 같은 괄목할 만한 성과를 얻을 수 있었으며, 교수들의 산업체 방문을 통한 산학협동의 계기 마련에도 커다란 성과를 얻었다. We have upgraded the STC(Special Topics Course) program, which has been carried out in our university since 1995, to more structured program so that we could train our chemical engineering students better. This program was geared to help students find better jobs and enter well-recognized graduate schools. Consequently, we had most students successful in job searches as well as entrance exams for graduate school; besides, those who actively participated in our STC program were able to attain better professional knowledge and acquire various professional engineers certificates. On top of that, this program allowed us to build up closer relationships with our students. We also made university-industry cooperation possible through our visits to industries nearby.
