이성규(Seonggyu Lee),권원태(Won Tae Kwon) 대한기계학회 2015 大韓機械學會論文集B Vol.39 No.4
MC-50 사이클로트론에서 방출되는 양성자 빔은 직경이 2-3 mm 의 가우시안 분포를 가진다. 이렇게 넓게 조사되는 양성자 빔은 작은 스팟과 정밀한 위치정밀도를 요구하는 반도체 식각, 마이크로 머시닝 등에는 사용될 수 없다. 본 연구에서는 좀 더 경제적인 대안으로 양성자 빔을 마이크로 홀에 통과시켜 수십 μ m 의 직경을 가지도록 조형하는 방법을 제시하였다. 양성자 빔의 조형을 위하여 평균 직경 21μ m, 두께 9mm 의 세장비 428 의 마이크로 홀을 제작하였다. 마이크로 홀과 양성자 빔을 정밀하게 정렬하여 양성자 빔을 조형하였다. 이렇게 조형된 양성자 빔을 이용하여 수십μ m 크기의 마이크로 구조물의 가공성 확인 실험을 실시하였다. 또한 GEANT4 를 이용한 전산모사를 이용하여 해석한 후, 실험결과와 비교하고 분석하였다. 본 연구를 통하여 MC-50 사이클로트론이 조형 장치와 함께 20 마이크론 대의 3 차원 구조물 제작을 위한 마이크로 공정기술에의 사용 가능성을 확인하였다. The diameter of a proton beam emanating from the MC-50 cyclotron is about 2?3 mm with Gaussian distribution. This widely irradiated proton beam is not suitable for semiconductor etching, precise positioning, and micromachining, which require a small spot. In this study, a beam cutting method using a microhole is proposed as an economical alternative. We produced a microhole with aspect ratio, average diameter, and thickness of 428, 21 μm, and 9 mm, respectively, for cutting the proton beam. By using this high-aspect-ratio microhole, we conducted machinability tests on microstructures with sizes of tens of μm. Additionally, the results of simulation using GEANT4 and those of the actual experiment were compared and analyzed. The outcome confirmed the possibility of implementing a micro process technology for the fabrication of three-dimensional microstructures of 20 micron units using the MC-50 cyclotron with the microhole.

칭기스 한(Činggis qan) 칭호(稱號) 연구(硏究)
이성규(Seonggyu Lee) 한국몽골학회 2022 몽골학 Vol.- No.71
Although there have been many studies on the title of the Činggis qan, there is no established theory. However, recently, some scholars in China are making new claims about the title of the Činggis qan based on the theories of The Jami‘ al-Tawarikh of Rashid al-Din and the elder scholars, but this is far from the original meaning. In this study, from the point of view that Eastern Mongolia, the hometown of the Činggis qan, is related to the Khitan, and that Korea is historically and culturally closely related to Mongolia, the vocabulary related to the Činggis qan in Khitan and Korean was searched. Prior to the full-scale study of the Činggis qan, we looked at the Uygurjin data in which the notation of the Činggis qan appeared, and also looked at the data and researchers explaining the title of the Činggis qan. In previous studies, it was analyzed that the title of the Činggis qan had the meanings of 'sky [天], firmness (堅固), courage (勇猛), honesty (正直), truth (眞實)’, etc. and plural suffixes were connected. It is known that Činggis qan is analyzed as Činggis + qan, and that qan is the word for the leader of the northern peoples. Existing theories have analyzed that plural suffix are connected to, but considering the characteristics of Mongolian, the Altaic language, it is reasonable to analyze it as ‘Čing + gis’. Scholars have already revealed that Čing of Činggis means ‘true, reality, honest’. On the other hand, gis was analyzed as a plural suffix or person in previous studies, but it is far from the original meaning. It was confirmed that the Khitan founder Gisu(奇首 *kĭɕ) could be connected with the gis of Činggis, and it was understood that the founder also had the meaning of ‘first, beginning, top’. The progenitor words of Korean: Goguryeo's gaecha(皆次 *kaiči) and gaeso(蓋蘇 *kasu), Baekje's gilji(吉支 *kici, *kisi), giza(gizɔ), and Silla's geose(居世 *kĭɕ), geoseo(居西 *kĭs), geosul(居瑟 *kĭʃ), and gilsa(吉士 *kĭʤĭ) are connected with gis of Činggis. The tale of bird that appears in the tale of the Činggis qan also appears in the tale of the Park Hyokgeose(朴赫居世) of Silla, which shows that the Činggis qan and the Park Hyokgeose are kings with the same personality, that is, they are the ‘first and true kings’.

본고는17~18세기몽골 불교사원에설치되었던전통의학교육기관인 만바다창의설립배경과 교육제도의 특징을 밝히는 데에 목적을 두었다. 몽골의 만바다창은 전문적인 의학교육을 통해 醫僧배출과 의학 연구, 진료를 함께 담당하였던 당시 몽골의 종합 의료 기관이었다. 본고에서는몽골만바다창의설립배경과의의를밝히고, 몽골의의승들이만바다창의교육을 체계화시키기위해 저술하였던몽의서들을참고서와교재, 지침서로분류하여설명하였다. 또한 6~7세부터20여 년 이상 지속되는만바다창의 전문의학 학습제도와 학승들의 출신 배경, 시험 및 학위 수여제도를 논의하였다. 몽골에는17~18세기불교사원을통해티베트의학이유입되었으며, 몽골인들은그의학체계에 몽골의 민간요법과 약재들을 적용하여 몽골인들에게 적합한 치료법으로 발전시켰다. 몽골만바다창의 교육제도 또한 티베트와 변별성이 있음을 본고의 논의를 통하여 확인하였다. 국내에 소개되지 않은 몽골전통의학에 대한 사적 소개를 시도하였다는 점에서 본 연구의 의의를 두고자 한다. 몽골의 전통의료교육기관이었던 만바다창의 교육제도를 살펴보는 작업은, 당시 몽골의 醫學史뿐만 아니라 몽골 불교사원이 가지던 기능, 몽골 전통교육제도의 단면을 고찰할 수 있다는 점에서 그 가치를 찾을 수 있다. The purpose of this study was to clarify the establishment & the background and an educational-system characteristic of Manba Datsan as the educational institution of the traditional medicine that had been installed in the Mongolian Buddhist temples in 17~18C. Manba Datsan in Mongol had been a specialized medical institution in Mongol at that time, which had been in charge of producing medical Buddhist monks, of researching into medicine, and of medical treatment through the specialized medicine education. This study examined the background of establishing the Mongolian Manba Datsan and described Mongolian traditional medicine books, which had been written by Mongol's medical Buddhist monks in order to systematize Manba Datsan's education, by classifying them into reference book, teaching material, and guidebook. Also, it figured out the specialized-medicine learning system in Manba datsan, which is continued for more than about 20 years from the ages of 6~7, the background of origin in scholar monks, and the examination & title award system. The significance of this study aims to be put in a point of having attempted the introduction of the books with a historical fact on the Mongolian traditional medicine, which had not been introduced to the country. A work of examining the educational system of Manba Datsan, which had been the traditional-medicine educational institution in Mongol, can be found its value in being able to consider the function that the Mongolian Buddhist temples had possessed, and the aspect of Mongol's traditional education system, as well as the medical history of Mongol in those days.

본 연구의 목적은 여성결혼이민자의 사회참여가 주관적 건강에 미치는 영향을 파악하고, 이 관계에서 지각된 차별의 매개효과를 검증하는 데 있다. 이를 위해 <2012년 전국다문화가족실태조사> 자료를 활용해 경로분석을 실시하였다. 인구사회학적 변인들을 포함하여 모형을 검증한 결과, 사회참여가 활발한 여성결혼이민자의 주관적 건강상태는 불량한 것으로 나타났고, 이 때 지각된 차별은 사회참여와 주관적 건강의 관계를 부분 매개하는 것으로 확인되었다. 연구결과를 바탕으로 여성결혼이민자의 주관적 건강상태를 개선할 수 있는 방안을 제시하였다. This study aimed to examine the mediating role of perceived discrimination in the relationship between social participation and self-rated health among female marriage immigrants in Korea. To this end, a path analysis was conducted to analyze the data derived from 2012 National Survey of Multicultural Families. The results indicated that social participation was negatively associated with self-rated health; perceived discrimination partially mediated the negative relationship between social participation and self-rated health. Based on the findings, a suggestion was made that could be usefully tapped into improving subjective health of female marriage immigrants in Korea.
