  • Rebels emerge after the late Joseon. Hong Gyung-rae will fight against the military by gathering dissatisfaction forces with regional and status discrimination. Gasan supervisor Jung - Si in the first battle. He urged him to surrender and participate in the rebellion, but Jung - Si refused to die. Surrounding officials did not protest and surrendered to the rebels. When Hong Gyeong-rae's rebellion subsided, the most damaging thing was the death of 2,000 people who were deceived and joined by Hong Gyeong-rae's propaganda. There would have been no death of the innocent people if the officials in charge of the government had actively defended them at the beginning of the rebellion. There is a need for a historical study on the time of the Gasan supervisor Jung-Si, who refused to surrender to the rebels and fought with death.

  • The Computer code KAIST-ADD LUFUNS has been developed to solve 3D compressible turbluent flow. This method employs Harten-Yee's modified upwind scheme in the explicit part and Steger-Warming Splitting in the implicit part. Flow past RAE wing-body aircraft has been computed for three different flow conditions. The result have shown good comparision with the experimental data. Baldwin-Lomax turbluence model is used for this computer code.

  • 임계마하수보다 큰 자유흐름 마하수에서는 충격파의 발생으로 인해 급격한 항력증가가 발생하므로, 임계마하수 증가는 고속 공기역학에서 중요한 분야로 다뤄지고 있다. Whitcomb R. T.에 의해 천음속영역에서 순항할 수 있는 초임계익형이 개발되었으나, 충격파 제어 기법들에 대한 실험적인 검증은 형상 제작의 어려움으로 인해 한계를 지닌다. 따라서 본 논문에서는 2D_Comp-2.1_P와 Prandtl-Glauert 압축성 보정식을 이용하여 NACA0012와 RAE2822의 임계마하수를 해석하고, 충격파 제어 장치 중 하나인 Bump를 RAE2822에 설치하여 임계마하수를 향상시키기 위한 연구를 수행하였다. 연구 결과 충격파를 압축파로 분산시켜 충격파의 강도를 약화시키고, 양항비의 4.7% 증가를 확인하였다. 따라서 Bump를 설계한 RAE2822가 기본 익형보다 높은 천음속 조건에서 효율적인 공력특성을 가지는 것을 확인하였다.

  • Many studies of experimental economics have produced outcomes which contradict the predictions of Nash equilibrium, which relies heavily upon the premise of selfishness of an individual. In the games involving contexts of social conflicts represented by the prisoners' dilemma game, the experiments yields outcomes quite different from what are predicted by the conventional wisdom. In order to fill this gap between the conventional Nash Equilibrium and experimental outcomes, non-selfish (or other-regarding) motives of human behavior are introduced and then a new equilibrium concept, RAE-equilibrium is developed. It is also proved that an RAE-equilibrium exists under quite general conditions. Then it is applied to the prisoners' dilemma game that some of the experimental outcomes can be explained.

  • This paper suggests a genealogy of romance in Chang-rae Lee's Native Speaker, A Gesture Life, and The Surrendered. A flexible textual performance and literary strategy spanning issues of beauty and love, romance in Lee registers the writer's distinctive diasporic negotiation with sites of departure and arrival, in particular with traumatic histories of the m/other country. Native Speaker resolves the crisis of public immigrant love within the compromise in the domestic melodrama. As Lee turns to the scenes of historical trauma in the twentieth century transpacific, romance becomes a key strategy through which his aestheticized framing and deframing of comfort woman is performed and the Korean War finds odd comfort in the aesthetic energy of perverse care in Italy. Through the dehistoricizing movement outside of the historical into the realm of myth and nostalgia, Lee's diasporic romance breaks away from mandates of representation and works within the excess of mistranslation.

  • Korean Plecopteran research was started in 1921, and it has advanced greatly during last 20 years. Among families the family Nemouridae and Chloroperlidae are composed of plentiful species. Since North Korean Plecopteran research was begun in 1938, it made good progress by foreigners not North Korean in the 1970's. Subsequently a few species has been added up recently, and among families the family Perlidae and Nemouridae contain most abundant species. Totally Korean Plecoptera consists of 43 species in 25 genera in 10 families, and North Korean 37 species in 26 genera in 10 families. Among them 13 species are common in both. And Korean names of Plecopteran species were mixed in Hangeul-type and Chinese-type, on the other hand in North Korean names there were some cases of Hangeul-type, but most of species have no Korean names. In Korea, particularly Ministry of Environment designated and controlled domestic biological resources as Korean Species that Require Approval when shipping abroad and Korean endemic species, which include 9 species and 11 species in Plecoptera respectively. Finally two genera and four species gained new Korean names as follows: genus Megaleuctra (Keun-Kkoma-Gang-Do-Rae-Sok), genus Haploperla (Han-Nok-Saek-Gang-Do-Rae-Sok), Nemoura brevicercia (Min-Gang-Do-Rae), Nemoura espera (Kkot-Min-Gang-Do-Rae), Amphinemura baei (Je-Ju-A-Ga-Mi-Min-GangDo-Rae) and Amphinemura rai (A-Ga-Mi-Min-Gang-Do-Rae).

  • Ka Rae Do Gam Eui Gue(嘉禮都監儀軌) is records of wedding ceremonies of empresses and crown princesses in Yi Dymasty. This recors shows the sorts of court costume and the required quantity of dress material. And illustrations of ceremonial procedure in the Eui Gue give us an obvious picture of those clad in the costume. This study aims at analysing the secords of female costume and inuuiring into the transitional process of the conrt costume.
