  • 림프관 조영술에 사용하는 리피오돌의 온도에 따른 이동 속도 차이를 분석하여 검사의 효율성을 높이고 환자 및 시술자의 피폭선량을 감소하는 방안을 연구하였다. 0.014 inch Support Catheter에 Balloon Inflator를 이용하여, 일정한 압력으로 리피오돌을 주입하는 장치를 자체 제작한 후 Connecting Tube에 리피오돌을 충전하고 전열 기구를 이용 26 ℃, 36 ℃, 46 ℃의 온도로 주입과 동시에 Fluoroscopy를 촬영하였다. 리피오돌이 Support Catheter에서 20 cm 이동하는 시간을 측정하여 분석하였고, 통계적 유의성 확인 후 리피오돌을 적정 온도로 유지하는 방법을 고안하였다. 46 ℃ 환경에서 이동시간 평균은 11초, 36 ℃에서는 평균 13초, 26 ℃에서는 평균 17초 소요되었다. 리피오돌은 온도 상승에 따라 이동시간이 유의한 차이를 보였으며(p < .001), 온도가 높을수록 이동 속도가 빨라지는 것을 확인하였다. 림프관 조영술 시 상온에 노출된 리피오돌을 바로 주입하는 것보다 일정 온도로 가열하여 사용할 경우 주입속도를 높일 수 있는 동시에 림프관 안에서의 이동 속도를 향상할 수 있다.

  • PASKYULA was formed in September, 1923 through the union of artists involved in two art groups: Kim Ki-Jin, Kim Bok-Jin, Yeon Hak-Nyeon who had previously participated in the ToWolHoi, and Park Young-Hi, Lee Sang-Hwa, An Seok-Ju, former members of the BaeckJo. After its founding, the PASKYULA artists had been searching for the social function of art to reform the harsh reality of Minjung and the nation with criticism toward society as well as art world. Their art theory for MinJung could grow relatively ease in relation to changing social and political conditions in the early 1920s. In August, 1925, PASKYULA organized the Korea Artista Proletaria Federatio with the YeomGunSa, and laid the groundwork for Proletariat art movement which was regularized in the late 1920s. From PASKYULA up to the early state of KAPF, the theory of art advocated by Kim Bok-Jin and An Seok-Ju could be summarized as "art for MinJung". At that time, widely ranging discourses on MinJung, however, was spawned in art theory, because many intellectuals-including artists and writers-begun to pay more attention to MinJung, who emerged as one of the social forces after the Samil Independent Movement. Sometimes, MinJung was construed as the target of enlightenment from a negative viewpoint. On the other hand, several intellectuals under the influence of individualism asserted that the discussion itself on MinJung exerted an evil influence on art. In contrast of these cases, the PASKYULA artists including Kim Bok-Jin, An Seok-Ju perceived that MinJung had the potential to change society, and regarded them as "a creator of genuine civilization and art". In the PASKYULA artist's writings, the concept of MinJung was often overlapped with the meaning of the Choson nation suffering under colony. Although their concept of MinJung was transformed gradually into the proletariat as they were under the strong influence of socialism, it did not change that they grasped the realities of the whole Choson Peninsula through the proletarian consciousness. In the early state of PASKYULA, the methodology for social function of art was presented in a twofold manner. First of all, Kim Bok-Jin emphasized on the necessity of education to improve MinJung's way of life through art, and it was embodied by the organization of ToWol Art Workshop and public lecture. Also, he championed "the popularization of art", which was one of methods to distribute art to MinJung. According to the PASKYULA artists, art should be not art for art' sake but art for MinJung. That was why they advocated the convergence of art and MinJung's life. Especially Kim Bok-Jin affirmed a link between art and industry because he considered industry the field inextricably linked with MinJung's life. In this context, his idea could be read as the generalization and equalization within the framework of possession. Kim Bok-Jin thought that the social ramifications of capitalism deprived MinJung of their right to enjoy art, and emphasized the artist' social role to return the right to them. That is, the even distribution of art was mainly discussed than the contents of art in the half of 1920s. By 1925, the contents of art itself became an issue in the PASKYULA art theory, and it was based in realism. Kim Bok-Jin and An Seok-Ju insisted that art should be reflection of real life. At that time, realism acquired the representation of MinJung and the nation's realities not realistic style. In fact, the various Western art styles including Futurism, Constructivism, Cubism etc. were exploited in the PASKYULA's visual images. Western art, target of criticism on theory, was selectively adopted in the works which were produced by Kim Bok-Jin and An Seok-Ju. Kim Bok-Jin's MoonYeUnDong cover design was conceived of as the example in which Western art was adopted with it's ideology under the influence of MAVO, while Western art shown in An Seok-Ju's illustrations served as a decorative function in many cases. Especially, An Seok-Ju attempted the various styles of Western art simultaneously, which may be seen as representing that PASKYULA did not have a firm ideology for their style. Also, it can be read as showing his hasty zeal to overcome Western art rapidly. The wish to establish "art for MinJung" as soon as possible was accompanied with the will to jump over the all steps of Western art though it was superficial. This aspiration of PASKYULA was expressed through the mass media, which had the potential for communicating to MinJung. At this point, there was a significant disparity between PASKYULA and another art groups in the first half of 1920s. However, the PASKYULA's method on the basis of the mass media could not but have a certain limitation because of the medium's properties. Nevertheless, PASKYULA' attempts may be considered to be valuable in sense that they expended the boundaries of Korean modern art into the commercial art questioning the matter of the distribution for art.

  • 위장조영검사는 위장에 바륨 또는 가스트로그라핀과 같은 조영제를 투여한 후 X선을 투과하여 진단하는 검사로서 일시적인 변비나 복통 외 특별한 부작용이 없는 것이 장점으로 위장계통의 질환 진단에 많이 이용되고 있다. 하지만 수검자의 검사에 대한 전반적인 이해부족으로 인한 검사 중 부적절한 움직임과 호흡조절로 화질과 검사의 정확성이 저하되는 경우가 빈번히 발생한다. 검사의 정확성 향상과 화질 개선의 방법으로 위장조영검사의 검사 과정과 주의할 점을 동영상으로 제작하여 검사 전 대기시간을 이용하여 시청하게 함으로써, 동영상을 이용한 교육이 화질 개선과 검사의 정확성 향상에 어느 정도 효과가 있는지 조사하였다. 2014년 위장조영검사 수검자 2,940명, 2015년 위장조영검사 수검자 3,076명 중 각각 30대부터 80대까지 10명씩 무작위 선출한 60명을 대상으로 교육 전, 후의 영상을 평가하였다. Image J 프로그램을 이용하여 각 영상의 프로파일에 대한 반치 폭을 측정함으로써 영상을 평가하였다. 반치 폭은 교육 전 0.208 mm, 교육 후 0.133 mm로 나타났다. 따라서 검사 전 동영상교육이 화질 개선에 효과가 있다는 것을 알 수 있었다.
