김혁길(Kim, Hyuk Gil),윤홍식(Yun, Hong Sik),황진상(Hwang, Jin Sang),정태준(Jeong, Tae Jun) 한국측량학회 2013 한국측량학회 학술대회자료집 Vol.2013 No.4
본 연구의 목적은 우주측지관측센터 내의 측량 기준점들 간의 위치관계를 정립하는 콜로케이션 측량에 따른 VLBI 안테나의 기준점을 결정하는 것이다. 이를 위하여 결합측량에 필요한 VLBI 안테나 상의 반사타겟 위치를 결정하였으며, 그에 따른 최적의 결합측량 방안을 수립하였다. VLBI 안테나에 부착한 반사타켓에 대한 토탈스테이션 측량을 수행하여 안테나 기준점의 위치 정확도를 평가하였다. The purpose of this study is to determine the reference point of the VLBI antenna based on co-location to establish a positional relationship between surveying reference points in the Space Geodetic Observation Center. For this, we determined the position of reflection target on the VLBI antenna and established the best method of co-location. Then we evaluated the accuracy of VLBI antenna reference point as precise total station surveying on reflection targets attached to the VLBI antenna.

본 연구의 목적은 중국 주식시장의 제도변화에 따른 정보효율성 변화를 분석하기 위한 것이다. 분석을 위해 상해ㆍ심천 증권거래소 AㆍB주 시장의 일별 종가지수를 이용하였으며, 각 시장에 요일효과(day-of-the-week effect)의 존재유무를 검정함으로써 그리고 조건부분 산 모형의 ARCH 항과 GARCH 항의 계수값을 비교함으로써 제도변화에 따른 중국 주식시장의 효율성 변화를 알아보았다. 분석결과 요일효과 모형을 이용한 경우 A주 시장은 규제하ㆍ개방하 모두에서 요일효과가 존재하지 않는 것으로 분석되었고 B주 시장은 규제하의 경우에는 화요일효과가 존재하는 것으로 나타났지만 개방하의 경우 요일효과가 존재하지 않는 것으로 분석되었다. 조건부분 산 모형을 이용한 분석에서는 모든 시장에서 개방으로 인해 오히려 효율성이 감소한 것으로 분석되었다. 또한 상해ㆍ심천 A주 시장은 제도변화로 비대칭적 분산구조가 사라지는 것으로 나타났다. 그러나 상해 B주 시장은 음(-)의 충격에 더 큰 변동성을 나타내는 비대칭적 분산구조를 가지는 것으로, 심천 B주 시장은 이러한 효과가 발생하지 않는 것으로 분석되었다. 이를 종합하면, 상해ㆍ심천 A주 시장은 규제하ㆍ개방하 모두에서 요일효과가 존재하지 않는 효율적 시장이지만 개방을 통해 오히려 효율성이 감소한 것으로 분석되었다. 그러나 상해ㆍ심천 B주 시장은 이와 다르게 개방으로 인해 효율적인 시장으로 변화하였지만 효율성이 감소하는 것으로 분석되어 두 분석모형에서 상반된 분석결과가 도출되었다. The purpose of the study is to analyze the changes in information efficiency according to liberalization of the Chinese stock market. For analysis purposes, daily closed indexes of the Shanghai and Shen Zhen stock exchanges' AㆍB share market have been utilized. And, by the proof of each market's day-of-the-week effects' existence and the comparison between ARCH type model's ARCH and GARCH clauses' coefficients, this study aims in examining the efficiency of Chinese stock markets' change through liberalization. According to the regression analysis, under regulation and liberalization, the day-of-the-week effect does not exist in A share market. However in B share market, Tuesday effect existed under regulation while nothing occurred under liberalization. In the analysis using the ARCH type models, all of the markets proved to be even decreased efficiency to the liberalization of the stock market. In addition, the Shanghai and Shen Zhen's A share market proved that an asymmetrical dispersed market structure disappeared to the liberalization. Shanghai's B share market appeared to react more to the negative shock and transform into an asymmetrical dispersed market structure. However Shen Zhen's B share market proved to stay unchanged against liberalization. In sum, Shanghai and Shen Zhen's share A market proves to be an efficient market as the day-of-the-week effect does not exist in both regulation and liberalization, however, efficiency decreased by liberalizing the market. Shanghai and Shen Znen's B market liberalization changed efficiently through liberalization but efficiency decreased and two opposite results were drawn from the two analysis models.

김혁길(Kim, Hyuk Gil),황진상(Hwang, Jin Sang),윤홍식(Yun, Hong Sic) 대한공간정보학회 2015 대한공간정보학회지 Vol.23 No.2
본 연구에서는 근접사진측량의 DLT와 부가변수에 의한 광속조정법을 활용하여 타겟에 대한 3차원 위치좌표를 산출하고, 결과의 정확도에 대한 분석을 수행하였다. 이를 위하여 다수의 타겟이 부착된 실험환경을 구성하고, 토탈스테이션을 활용한 기준점측량을 수행하여 각 영상에 대한 카메라 캘리브레이션과 표정결과를 산출하였다. 정확도 분석을 위하여 스테레오 영상에서 동일하게 선점된 타겟에 대한 3차원 위치좌표 성과를 산출하고, 그 결과를 토탈스테이션으로 측정된 기준좌표와 비교하였다. 스테레오 영상에 대한 사진좌표 측정 시, 원형타겟에 대한 중심점을 측정하기 위한 타원 fitting 과정을 수행하고, 그 결과를 타겟에 대한 사진좌표로 활용하였다. 연구의 결과, 스테레오 영상 기반의 근접사진측량 방법으로 계산된 위치좌표는 약 1cm 미만의 최대 오차범위 내에서 평균 4mm 미만의 편차로 산출됨을 확인할 수 있었다. 이러한 결과를 통해 정밀한 정확도가 요구되는 다양한 근접사진측량 분야에 본 연구의 결과를 활용할 수 있을 것이라 판단된다. In this study, the 3D position coordinates were calculated for the targets using DLT and self-calibration bundle adjustment with additional parameters in close-range photogrammetry. And then, the accuracy of the results were analysed. For this purpose, the results of camera calibration and orientation parameters were calculated for each images by performing reference surveying using total station though the composition of experimental conditions attached numerous targets. To analyze the accuracy, 3D position coordinates were calculated for targets that has been identically selected and compared with the reference coordinates obtained from a total station. For the image coordinate measurement of the stereo images, we performed the ellipse fitting procedure for measuring the center point of the circular target. And then, the results were utilized for the image coordinate for targets. As a results from experiments, position coordinates calculated by the stereo images-based photogrammetry have resulted out the deviation of less than an average 4mm within the maximum error range of less than about 1cm. From this result, it is expected that the stereo images-based photogrammetry would be used to field of various close-range photogrammetry required for precise accuracy.

기품론(氣稟論)에 관(關)한 문헌적(文獻的) 고찰(考察)
김혁,김달래,Kim, Hyuk,Kim, Dal-rae 사상체질의학회 1998 사상체질의학회지 Vol.10 No.1
The objective of this article is to induce that the conception of 'Qi-jul(氣質) and Qi-pum(氣稟)' was introduced to the Sasang(四象) Constitutional Medicine from bibliographic study on the theory of 'Qi-pum(氣稟)'. The conclusions summerized as followings. 1. In the oriental medicine, qualitative difference of 'zheng-qi(正氣)' among the individuals, the opposing power against a disease, is regarded as constitution. Having been used as 'nature(素)', 'quality(質)' and 'character(氣質)' in the oriental medical book, the word of 'Che-Jil(體質)' was used in good earnest at the end of 'Qing(情)' dynasty. 2. The nature(性) is divided into two, original nature(本然之性) and charicteristic nature(氣質之性) in the 'New confucianism(新儒學)' and the former means a principle(理), is a pure and good thing and used as a conception of universality, the latter is a principle of character and a imperfect imitation of principle(理). 3. It was repeatedly confirmed that 'Qi-jil and Qi-pum' meant the difference among the individuals by the dispute of 'Li-Qi(理氣)' caused by Lee Hwang(李滉) and Lee Yi(李耳) and by that of 'Ho-Rak(湖洛)' in the Ch'o-son(朝鮮) dynasty. 4. Han Sok-Ji, based on Meng-Zi(孟子)'s doctrine that man's inborn nature is good, criticized the theory of 'Qi-pum' which was 'Zhu-Zi(朱子)'s opinion and his opinion about the life(命) was thought to clue to the classification of the 'Sasang(四象)' invented by Lee Je-Ma as Park Se-Dang's theory that everyone has common nature but has different life(命). 5. By introducing the theory of 'Qi-pum' and the conception of life(命) which was understood as a special character by Han Sok-Ji and Park Se-Dang to Sa-sang constitutional medicine, Lee Je-Ma explained the reason why each man who was classified four constitutions, 'Taiyang'(太陽), 'Taiyin'(太陰), 'Shaoyang'(少陽), 'Shaoyin'(少陰), had the different formation of the visceral department(臟局).
