A single, tractable, special case of the problem of continuous mixtures of beta distributions over their parameters is considered. This is the uniform mixture of generalized arc-sine distributions which, curiously, turns out to be linked by transformation to the Cauchy distribution.

We compare a coding space which has an ultra metric with the unit interval which has an associated generalized dyadic expansion. The two spaces are not homeomorphic but dimensionally equivalent in the sense that the Hausdorff and packing dimensions of the corresponding distribution sets in the two spaces coincide.

An orientation-shift model for unit random vectors in $R^3$ is defined. The Euler angles are introduced to parametrize orientation-shifts and their moment estimators are found. Through the analytic perturbation method, the asymptotic distributions of the estimators are obtained.

A simple model of the galactic mass distribution consisting of one sphere and two spheroids with different eccentricities is considered. The resulting model is found to be consistent with the recent observations of the galactic rotation as well as suggested shape of the Galaxy.

Large sample test of homogeneity for a panel of more than two seasonal autoregressive processes is derived and its limiting distribution is found. Detailed results are shown for the important special case that the seasonal and nonseasonal autoregressive components are both of order one.

'96년도 국내유통산업은 커다란 지각변동의 해로 예측된다. 유통시장 전면 개방으로 할인업태를 앞세운 외국 유통업체의 진출이 본격화 되면서 유통시장의 대변혁을 예고하고 있다. 특히 정보통신 시스템의 발달로 기존의 제조, 유통, 소비의 경제 순환시스템도 대전환기를 맞고 있는 실정이다. 미국이나 일본등 경제 선진국에서 보여주는 멀티미디어 및 PC통신을 이용한 기업경영의 발전이 괄목할만하며 이에 따라 제조기업이나 유통기업들이 그 대응에 절치부심한다.(중략)
