Linear Combination Analysis Using GPS Data

Park, Woon-Yong,Lee, Dong-Rak,Back, Ki-Suk,Hong, Jung-Soo 東亞大學校 建設技術硏究所 2005 硏究論文集 Vol.28 No.2

We can process and compute the position, velocity and time by satellite signals of GPS. The signals are used to compute positioning of three dimensions and timing offset of the receiver clock when we can track the tour satellite signals at least. One of the specified aims is to use less expensive single frequency code/carrier phase GPS receivers, which are typically around half the price of dual frequency receivers. In the study, the author analyzed the accuracy and applicability of frequence linear combination using triangulation points evaluated distance limitation.

신경회로망을 이용한 터빈로타 디스크 키웨이의 결함 검출

이병우,이종오,윤운하,이병우,서원찬,이종규 한국비파괴검사학회 2003 한국비파괴검사학회지 Vol.23 No.1

최근 터빈 로타 디스크 키웨이에서 많은 응력부식균열이 발견되었으며, 터빈설비의 중대한 파손을 예방하기 위해 이러한 균열은 조기에 검출 및 평가되어야 한다. 본 연구에서는 초음파탐상의 RF(radio frequency) 신호를 역전파 알고리즘에 근거한 신경회로망에 적용하여 키웨이 주변의 균열에 대한 위치, 크기 및 방향성을 평가하였다. 각 반사영역에서 수신된 여러개의 피크로 나타나는 RF 신호를 각 반사영역에 대해 하나의 최대 피크를 가지도록 처리한 후, 트랜스듀서의 위치 정보와 각 반사파의 도달시간이 들어있는 주사 데이터를 작성하였다. 이 주사 데이터로부터 각 반사영역 사이의 시간차이와 트랜스듀서의 위치 정보를 신경회로망에 적용한 결과 키웨이에서 시작된 균열의 위치, 크기 및 방향성을 평가하는데 유용함을 알 수 있었다. A number of stress corrosion cracks in turbine rotor disk keyway in power plants have been found and the necessity has been raised to detect and evaluate the cracks prior to the catastrophic failure of turbine disk. By ultrasonic RF signal analysis and using a neural network based on back-propagation algorithm, we tried to evaluate the location, size and orientation of cracks around keyway. Because RF signals received from each reflector have a number of peaks, they were processed to have a single peak for each reflector. Using the processed RF signals, scan data that contain the information on the position of transducer and the arrival time of reflected waves from each reflector were obtained. The time difference between each reflector and the position of transducer extracted from the scan data were then applied to the back-propagation neural network. As a result, the neural network was found useful to evaluate the location, size and orientation of cracks initiated from keyway.

특집논문 : 의례로 읽는 화계사 안팎의 문화

이성운 ( Sung Woon Lee ) 한국불교사연구소 2014 한국불교사연구 Vol.4 No.-

이 글은 ‘의례’라는 키워드로 화계사 안팎의 역사와 문화를 읽어낸, 약간의 문학성을 띤 논문이라고 할 수 있다. 제일 먼저 ‘등촉(燈燭)’이라는 단어를 통해 화계사의 역사를 읽어보았다. 첫째, 1522년 서평군 이공(李公)의 제의로 신월 화상이 부허동에 있던 보덕암을 옮겨 현재의 화계사 자리로 옮겨 건립하여 화계사라 하였고, 1618년 화재로 전각이 소실되자 덕흥대원군 가문의 보시에 의해 1619년 초 중창되었으며, 1866년 흥선대원군(1820~1898)의 시주로 삼창된, 화계사의 역사에 대해, 등과 촛불을 밝히는, 의례의 행위에 빗대 풀어보았다. 희미하게나마 전승돼온 역사를 ‘희미한 등촉’이라고 하였고, 역사의 소용돌이 속에 법등을 이어온 사실을 ‘풍전의 법등’이라고 하였으며, 그래도 법맥이 꺼지지 않고 이어온 사실을 ‘상승의 법등’이라 하며 화계사 안팎의 역사와 의례 문화를 살펴보았다. 둘째, 불전(佛殿)에 공양하고 승려에게 재(齋)를 올리는 행위는, 부처님 재세 때부터 있어온 출가와 재가의 관계를 이어주는, 보시 행위이다. 부처님이나 수행자들은 신도들에게 법의 보시와 두려움 없음을 베풀고, 신도들은 공양물을 베풀어 승려들이 수행에 전념할 수 있도록 한다. 초기불교시기에는 탁발에 의지하였으나 이후 사원에 기진(寄進)된 장원에서 생산된 생산물에 의해 승단이 유지되었는데, ‘궁절’이라고 불린 화계사에는 궁인들의 공불행위가 이어졌다. 화계사 관음전에 자수관세음보살을 모신원주(願主) 조대비(1808~1890)는 1880년 불전의 양식을 마련하기 위해 재산을 출연하여 농토로 바꿔 매년 공양 올리는 양식으로 삼도록 하였고, 또 관음전에 양식을 헌공하였다. 아울러 사중(寺中)의 스님들도 1905년 성도계를 조직하여, 자타의 성도를 위해 공양을 마련하는 등 사부대중이 공불에 흔연히 동참하고 있다. 셋째, 염불(念佛)은 부처님의 명호를 염송하는 수행인데, 난행도(難行道)로 알려진 참선과 달리, 염불은 ‘이행도(易行道)’로서 재가불자들도 쉽게 동참할 수 있는 수행이다. 화계사 대방은 염불방으로 궁인들이 상사(上寺)하여 염불을 수행하였다고 보인다. 만일 동안 염불을 수행하는 ‘만일염불회’가화계사에 결성된 것은 1910년이었으며, 입적을 앞 둔 염불행자 월명 화상이 평생 이룬 전답을 출연함으로써 가능하였다. 간경(看經)·참선(參禪)과 더불어 삼문(三門)수행으로 널리 행해진 염불은, 조선 중기 이후 한국불교의 주요한 수행이었으며, 그 공덕은 지대하다. 화계사 만일 염불이 회향되었다고 보이는 1930년대 후반 이후 20여 년이 채 지나지 않은 시점에, 화계사에 고봉·숭산 등 눈 밝은 선지식들이 바랑을 내리게 된 것도 염불의 득과라고 할 수 있을 것이다. 화계사의 선사 숭산 스님이 국제포교 나서 큰 성과를 이룬 것도, 꽃이 아름답고 계곡이 아름답고 절이 아름다운 화계사에서 시작되었다. 이후 화계사에는 국제선원이 개원되어 세계불교의 한 중심지로 자리매김하게 되었다. 국내외에서 화계사를 찾아 선대 덕 높은 수행자들의 수행과 의례를 따라, 불전에 공양하고, 염불하고, 참선하며 세계일화를 실천하는 이들이야말로, 꽃·계곡·절과[三美] 더불어 화계사의 사미(四美)라고 하겠다. This essay is a bit of literary writing on the history and the culture around Hwagye Temple in veiw of the keyword, ‘Euirye(儀禮, ritual)’. Above all, the history of Hwagye Temple is considered with the word, ‘a lamplight and a candlelight(燈燭)’. Firstly, Sinwol Hwasang(virtuous monk) moved Bodeok Hermitage located in Buheodong to the current site of Hwagye Temple, built it and named as Hwagye Temple with accepting Seopyonggun Mr. Lee`s suggestion in 1522, and it was reconstructed thanks to the donation(Dana) of Deokheung Daewongun`s family in the early 1619 after its sanctum was burned down by a fire in 1618, and then rebuilt again with Heungseon Daewongun(1820~1898) offering in 1866. This history of Hwagye Temple is illustrated compared to the practice of the protocol lightening a lamp and a candle. The history and the ritual culture around Hwagye Temple is considered in that the history passed down even faintly is described as ``dim light of a lampe and a candle``, the fact of having inherited Beopdeung(法燈, the lamp of Dharma) in the historical maelstrom as ``Beopdeung(the lamp of Dharma) in the wind``, and the case of Beopmaek(法 脈, the Dharma lineage) handed down without disconnection as ‘the inter-successissive lamp of Dharma`` Secondly, the practice of offering to Buljeon(佛殿, Buddha sanctum) and holding Jae(齋, offering ritual) to monks and nuns is that of donation(dana) which has been carried out since Buddha`s lifetime and liaises between Sangha and the laity. Buddha and practitioners give lay people Dharma-offering and fearlessness and lay people give offerings so that monks and nuns may devote themselves to the discipline. Sangha depended on Takbal(托鉢, mendicancy) during the Early Buddhism period but it was maintained with the produce from the manor contributed to the temple since then, and Hwagye Temple called as Palace Temple was supported by court ladies who kept Gongbul(供佛, offering to Buddha). Her highness, Cho(1808~1890), the devote patron who enshrined an embroidered image of Gwanseumbosal(觀世音菩薩, Avalokite.vara) at Gwaneumjeon(觀音 殿, Avalokite.vara sanctum) in Hwagye Temple, exchanged her contributed property into farm land in order to provide food to Buljeon(Buddha sanctum) and made it food for Gongyang (供養, offering) to dedicate every year and consecrated food to Gwaneumjeon( Avalokite.vara sanctum) again. Also, monks and nuns in the temple organized Seongdogye(成道., traditional private fund for attaining enlightenment) in 1905 so that they arranged offering for the sake of their own and others` Seongdo(成道, attaining enlightenment). Like this, Sabudaejung(四部大衆, the fourfold community) participate in offering to Buddha all together. Thirdly, Yeombul(念佛, chanting Buddha), which is to chant Buddha`s name, is the practice for the laity to take part in with ease as Ihaengdo(易行 道, easy path to enlightnement), contrary to Chamseon(參禪, meditation practice) known as Nanhangdo(難行道, difficult path to enlightenment). A large room in Hwagye Temple is a room for Yeombul(chnating Buddha) so that court ladies might visit it and practice it. ``Manil Yeombulhoe(ten thousand days Chanting Buddha assembly), which is to practice Yeombul(chnating Buddha) for ten thousand days, was organized in 1910 with Yeombul practioner, Wolmyong Hwasang(virtuous monk) contributing his lifelong farm land when he was about to do Ipjeok(入寂, Parinirvana). Yeombul(chnating Buddha) practiced widely as Sammun(三門, three gates) practice along with Gangyeong(看經, ardent reading of a sutra) and Chamseon(參禪, meditation practice), is the main practice of Koren Buddhism since the middle of Joseon Dynasty and its Virtue(Guna) is great. It can be the gains and the fruit(得果) for Seonjisik(善知識, learned and virtuous masters) such as Gobong, Sungsan, etc to take their Barang(a Buddhist sack) off at Hwagye Temple at the point of time when it hasn`t passed about 20 years after the late 1930s and when Hoihyang(廻向, Merit-transference) of ``Manil Yeombul(ten thousand days Chanting Buddha) was made. Sungsan Seonsa(禪師, Zen master) at Hwagye Temple has greatly accomplished international dissemination, which began at Hwagye Temple where flowers, the valley and the temple are beautiful. Since then, the interantional Seonwoen(禪院, Seon monastery) opens here and settles down as a center of World Buddhism. Those who visit Hwagye Temple at home and abroad, and give offerings to Buljeon(Buddha sanctum), practice Yeombul(chnating Buddha), meditation and Segye Ilhwa(世界一花, The whole world is a single flower), following the discipline and the rites of virtuous foregoers, are one of four beauties(四美) along with flowers, the valley, and the temple[三美, three beauties] of Hwagye Temple.

Three different treatments for induction of estrus in Korean native black goats were compared: follicle stimulating hormone(FSH, FSH-p^TM), FSH combined with MAP(intravaginal impregnated sponges, Veramix^ⓡ, containing 60 ㎎ medroxy progesterone acetate for 14 days), and FSH combined with progesterone(Ovaron^ⓡ, 10 ㎎ IM for 10 days) and PGF_2α(Lutalyse^ⓡ, 3 ㎎ IM at first FSH injection). FSH for inducing estrus and superovulation was given a total 20 ㎎ intramuscularilly in decreasing dosage injections twice daily over 4 days. The MAPs were withdrawn at the 3rd day of FSH injection. Estrus observations were conducted every 6 hours from last FSH injection for 24 hours by placing the does with fertile male goats. Estrus and superovulation were more successfully induced with treatment of MAP + FSH than other treatments(FSH only, or progesterone + PGF_2α + FSH) (estrus induction; 100 vs 42.8 and 71.4%, ovulation points; 11.4 vs 5.4 and 4.4, respectively). The effect of gonadotropin releasing hormone(GnRH) on the ovulation rate was also examined. However, no difference was observed for inducing ovulation with treatment or dosage(100 ㎍ 200 ㎍) of GnRH. Low midline laparotomies were performed, and then ovarian responses (ovulations and follicular development) were examined by exteriorization of the reproductive tracts. Ova were recovered from oviducts by retrograde flushing 60-146 hours after MAP removal, and were classified the developmental stages. Overall 66.1% (236/357) of recovery rate was obtained from 30 superovulated does. The optimal recovery time of microinjectable 1-cell zygotes was approximately 72-76 hours after MAP removal.

For elucidation of various parameter's effect on the reactive extraction of organic acidstrioctylamine(TOA)-diluents system, the association model, equilibrium constants and extraction factors(loading) were investigated . The organic acids rosed were propionic. succinic, masonic, and benzoic acid. Extractant was tertiary amine, TOA and diluents were butylaeohol, hexane, and benzene. It was concluded that the loading of monobasic acid of propionic acid were higher than that of dibasic acids of oxalic, and malonic acid with extranctant TOA. In the extraction of monobasic acid the extraction factor was not affected by the initial concentration of extractant amine, but in the extraction of dibasic acids the extraction factor was getting better with decreasing the initial concentration of amine. There was a strong effect of diluents upon the extractien factor, and the order of these factor was as shown below: xylene<Benzene<butylalcohol<choloroform<methylisobutylketone.
