There are two styles of Yoo(; ) Sang(;裳) in Koryo Women. One they wore the Snag(;裳) over the Yoo(; ), the other wore the Yoo(; ) over the Sang(;裳). In the Yoo(; ), Double breast styly was used for the adjustments of these clothes, Neckline and hem line were substituted by rectangular collar (;목판깃). Knot-button, Coat-string(;Okgolum), White straight collar (DongJung), side slit were used. In the Sang(;裳), Chimaheri(;치마허리)was mades of another fabric and Chima-string was dropped.

Bromolactonization of 2-substituted-1-cyclohexenyl-1-acetic acids with 1, 3-dibromo-5, 5-dime-thylhydantoin 9DBH) and potsssium tertiary butoxide (t-BuOK0 in anhydrous DMF was found to proceed in a highly regioselective manner. The reaction predominantly resulted in the formation of ${\betha}-lactones$ (greater than 96%).

The $S^1$-Eule characteristics of X is defined by $\bar{\chi}_{S^1}(X)\;{\in}\;HH_1(ZG)$, where G is the fundamental group of connected finite $S^1$-compact manifold or connected finite $S^1$-finite complex X and $HH_1$ is the first Hochsch ild homology group functor. The purpose of this paper is to find several cases which the $S^1$-Euler characteristic has a homotopic invariant.

When the low cost IMU is used, the result of the stationary self alignment is not suitable for navigation. In this paper, an in-motion alignment method is proposed to obtain an accurate initial attitude of a low cost IMU based GPS/INS integration system. To design Kalman filter for alignment, large heading error model is introduced. And then Kalman filter is designed to estimate initial attitude error as the indirect feedback filter. In order to assess performance of the alignment method, computer simulations are carried out. The simulation results show that initial attitude error rapidly reduces.
