이상의 결과를 정리하면 다음과 같이 요약할 수 있다. (1)Karman의 적분 방정식에 미소 거칠기 영향을 고려함으로서 디퓨져 닥트 표면의 경계층 계산에 응용한 결과 모멘트 적분법 및 실험치와의 비교에서 개선된 결과임이 확인되었다. (2) 국소 거칠기의 효과를 주는 방법으로는 Cole의 벽 및 와 법칙에 Clauser의 거칠기 함수와, 압력 기울기를 고려한 부가 형상계수 값으로 적분 방정식에 응용할 수 있다. (3) 국소 거칠기 분포에 의하여 경계층 특성을 교란시켜 표면 마찰력 계수를 줄일 수 있어 마찰력 손실을 줄일 수 있는 방안이 제시되었다.
With a modern microdensitometer and POSS glass copies, we have performed an automated star counting in two colors, blue and red, over the region containing Bok globule B361. Distribution of the measured extinction values over the projected angular distance from the cloud center was approximated by a power-law, and the resulting power-law indices for the blue and red are shown to be distinctly different from each other. The difference in the power-law index indicates that the mean dust size increases towards the cloud center. Possible physical causes for such size variation are briefly discussed.
We construct a simple photometric evolution model of galaxies based on the evolutionary population synthesis. In our models an exponentially decreasing SFR with a power law IMF is used to compute the UBV colors of galaxies from ellipticals to late type spirals. It is shown that the integrated colors of galaxies with different Hubble type can be explained by one parameter, SFR.
To analyse the royal marriage of Yi-Dynasty, the authors studied 'Kuk Hon Geong Rea', which is a historical record, published in 1749(King Yong-Jo), on the usage of marriage articles in the royal family. The essential steps or articles described in the record were as follows, Royal marriage of King : Wedding presents, black and red silks from the bridegroom's to bride's, proclamation of Queen and wedding ceremony(納采) (納徵) (冊妃) (親迎 尊雁 同牢). Royal marriage of Crown Prince : Wedding presents, black and red silks from the bridegroom's to bride's. proclamation of Crown Princess, wedding ceremony, and bride's gifts to her parents-in-law(納采) (納徵) (冊嬪) (親迎 尊雁 同牢) (朝見體). Royal marriage of Crown Princess : Wedding presents, black and red silks from the bridegroom's to bride's, wedding ceremony, bride's gifts to her parents-in-law(納采) (納徵) (尊雁 同牢) (見舅姑禮). Necessary articles for weddings were different according to royal status of the member in the royal family.
