나경수,이제희,박흥득,Na Kyung-Su,Lee Je-Hee,Park Heung-Deuk 대한방사선치료학회 2005 대한방사선치료학회지 Vol.17 No.2
Purpose : This test is designed to identify the validity of treatment plan by implementing real-time dosimetry by means of dose that is absorbed into PTV and OAR when preparing doses of 3D and POP plans. Materials and Methods : In treatment. error can be calculated be comparing Exp. Dose with the actual dose, which has been converted from 'the reading value obtained by placing diode detector on the area to be measured'. Same test can be repeated using Alderson-Rando phantom. Results : Errors were found: A patient(POP plan): 197.6/199=-1.2%, B patient(3D-plan): 199.9/198.7=+0.6%, C patient: 196/200=-1.5%. In addition, considering the resulted value of measuring OAR besides target-dose for C patient showed 96/200, representing does of 47%, the purpose of protection was judged to be duly accomplished. Also it was acknowledged the resulted value of -3.7% met the targeted dose within the range of ${\pm}5%$. Conclusion : Aimed for identifying the usefulness of pre-treatment dose measurement using diode detector, this test was useful to evaluate the validity of curing because it resulted in the identification of category to be protected as well as t dose. Moreover, it is thought to have great advantage in ascertaining the dose of target, dose of which is not calculated yet. Similar to L-gram before treatment, this test is thought to be very effective so that it can bring great advantages in the aspects such as validity of curing method and post-treatment plan as well.

아리랑은 우리민족에게 가장 널리 알려지고 애창되는 노래이다. 춘향전이 가장 널리 알려져 있는 서사라면 아리랑은 가장 널리 알려진 서정이라 할 것이다. 그것의 역사와 기능과 구조가 어떻든 아리랑은 민족의 문화유산이자 자산으로 자리를 확고히 하고 있다. 아리랑이 불리는 상황은 다양할 수 있다. 그러나 광주에서 광주시민들에 의해서 자발적으로 불렸던 특정 상황은 매우 비극적이면서도 초유의 사건과 함께였다. 5 · 18이 그것이다. 현대사에 있어서 최고의 비극이라 할 수 있는 5 · 18광주민주화운동에서 재창된 아리랑은 잘 알려져 있지는 않지만, 새로운 질서 창조를 위한 신화적 상황에서 불린 노래로 간주할 수 있다. 일종의 본풀이적 기능을 했던 것이다. “광주세계아리랑축전”이 2012년도에 시작했다. 많은 시민들은 아리랑과 광주 사이의 연관성에 대해 의심하고 있다. 광주가 과연 대표축제로서 아리랑을 채택할 수 있을 정도의 연고권을 가지고 있는지 의심하는 것이다. 아리랑이 불린 상황 자체가 새로운 질서 창조를 위한 신화적 사건이 벌여진 것이라면 이는 사회적 드라마, 또는 규칙적으로 반복되는 의례적 지지를 받아야 한다. 즉 도청 앞에서 아리랑이 불린 상황은 신화적 서사와 제의적 극화가 함께 해야 하며, 그런 점에서 “광주세계아리랑축전”은 광주정신을 투사할 수 있는 유력 장치의 일종이라 하겠다. Arirang is most widely known and sung by our people. If Chunhyangjeon is most widely known story, Arirang is most widely known lyricism. Regardless of its history, function, and structure, Arirang has been firmly established with its position as the national cultural heritage and asset. The situation to sing Arirang can be various. However, the specific situation when Gwangju citizens spontaneously sang it in Gwangju was along with very tragic and the first-ever event 5 · 18. Arirang, sung during 5 · 18 Gwangju Democratization Movement, which can be called the biggest tragedy in modem history, nevertheless not well known, however can be regarded as the song sung at a mythical situation for a new order creation. It acted a kind of the function of bonpuri. “Gwangju World Arirang Festival” began in 2012. Many citizens doubt the association between Arirang and Gwangju. They doubt whether Gwangju has an preemptive rights to adopt. Arirang as a representative festival. If the situation to sing Arirang itself was the mythical event to create a new order, that should be supported with social drama or regularly repeating ceremonial support. That is, the situation to sing Arirang in front of the provincial government office should be accompanied by mythical narration and ritualistic dramatization, in this respect, “Gwangju World Arirang Festival” can be said to be an influential tool to project Gwangju spirit.
한국전통주거(韓國傳統住居)에 나타난 가택신앙(家宅信仰)과 공간구성(空間構成)에 관한 연구(硏究)
천득염,나경수,손희하,나하영,Cheon, Deuk-Youm,Na, Kyung-Su,Son, Heui-Ha,Na, Ha-Young 한국건축역사학회 2001 건축역사연구 Vol.10 No.4
Living spaces are the results of social environment and also the reflection of the viewpoints by their residents toward human culture and society. Therefore, in studying living spaces, the true essence of the spaces could be easily distorted when cultural and symbolic motives and values are disregarded and only their apparent characteristics are looked into. Hence, it's necessary to simultaneously understand both physical dwelling spaces from architecture's view points and social ideas, simultaneously, of people who form and interact with the spaces. Hence, this paper tries to study housing religion which is one of shamanistic religions which, in turn, have been the fundamental element of ancient religions and came into existence on the basis of dwelling spaces. This study presumes that house religion may have been permeated with its creators' ideas about living and those ideas could be one of those factors which plays a role in organizing of dwelling spaces. As such, with these prior analyses, this thesis attempts to understand the meaning of various dwelling spaces via the characteristics and functionalities of various house spirits which are mentioned in a local house religion and also will find out spatial harmony of Korean traditional living spaces by way of corelations among living spaces, people, and personalized house spirits. Almost all traditional Korean houses have assigned a house spirit to their individual dwelling space. This means a traditional house was considered as a scared space in a secular world called human society and the space was actually intended to protect sacredness of dwelling places from earthliness outside. So when the hierarchy of house spirits in housing religion is projected to a Korean traditional house, it can be shown that a dwelling house as a building was personified to a respectable human status. In other words, it can be concluded that each space was synonymous with a dwelling place for each house spirit and was considered a sacred godly place. In a nutshell, not only each space in a Korean traditional house was a physical and functional space, but also it formed a scared spatial place along with the concept of house spirits intending to ward off disasters and enjoy a comfortable life through those religious symbols and meanings. Housing shamanistic religion which has long been existing with residents and their lives is seeped with the viewpoints of the residents toward life, and hence understanding the meanings and organization of Korean traditional housing can reveal commonly practiced principles of spatial organization of the traditional houses. Therefore an analysis of Korean traditional housing on the basis of humanistic social ideas will help learn Korea's traditional houses which need to be understood in various methods.

저궤도에서 운용되는 위성은 대기 저항에 의한 연료소모가 크며, 연료소모는 임무수명 및 발사무게에 영향을 미치게 되어 위성 형상에 따른 항력의 예측이 중요하다. 본 논문에서는 직접모사법을 이용하여 파라볼릭 안테나를 탑재한 저궤도 위성의 임무고도의 변화와 받음각에 따른 항력 및 항력 계수의 변화를 살펴보았다. 저궤도의 희박 기체의 거동을 모사하는 직접모사법의 적용성을 검증하기 위해 스타샤인(Starshine) 위성의 비행데이터를 이용하여 고도, 대기와 표면의 상호작용에 따른 항력 계수를 비교하였다. 결론적으로 계산결과로부터 저궤도 위성의 정밀한 궤도수명 계산에 적합한 항력 계수를 도출하였다. Consumption of the fuel on the satellite operating in low earth orbit, is increased due to the air resistance and the amount of increase makes the satellite lifetime decrease or the satellite mass risen. Therefore the prediction of drag force of the satellite is important. In the paper, drag force and drag coefficient analysis of the parabolic antenna satellite in low earth orbit using direct simulation monte carlo method (DSMC) is conducted according to the mission altitude and angle of attack. To verify the DSMC simulated rarefied air movement, Starshine satellite drag coefficient according to the altitude and gas-surface interaction are compared with the flight data. Finally, from the analysis results, it leads to appropriate satellite drag coefficient for orbit lifetime calculation.

한국형 달탐사선은 국가 우주개발계획에 따라 한국형 발사체인 KSLV-2(Korea Space Launch Vehicle 2)에 탑재하여 2020년 이후 발사될 예정이다. 한국형 달탐사선은 무인 탐사선으로 궤도선과 착륙선 2종으로 구성되며 발사체의 탑재능력에 따라 발사중량 550㎏ 이내의 소형 경량으로 개발되어야 한다. 달탐사선 구조체는 임무 탑재장비의 수용 뿐 아니라 발사 및 운용환경에서 견딜 수 있도록 충분한 강성과 강도가 요구된다. 본 논문에서는 한국형 달탐사선 구조모델의 설계에 대한 선행 연구결과를 기술한다. Korean lunar explorer will be launched by korean launcher KSLV-2 in the 2020s in accordance with national space development strategy. Korean lunar explorer is composed of two unmanned orbiter and lander and should be developed as small size and light weight within 550kg of launch mass due to launcher’s loading capability. A structure of lunar explorer is required to have sufficient stiffness and strength under launch and operational environment as well as to accommodate mission equipment. This paper describes the result of a preliminary study on structural model design for korean lunar explorer.
