We searched out in the votes data of the State of Florida at presidential election 2000. We used a multivariate regression analysis. We got there were several outliers including Palm Beach County. It means that we should analyze the number of disqualified ballots which were double-punched as well as the votes, to insist the " Butterfly Ballot" made Palm Beach outlier.

The enumeration of various classes of paths in the real plane has an important implications in the area of combinatorics wit statistical applications. In 1887, D. Andre [3, pp. 21] first solved the famous ballot problem, formulated by Berttand [2], by using the well-known reflection principle which contributed tremendously to resolve the problems of enumeration of various classes of lattice paths in the plane. First, it is necessary to state the definition of NSEW-paths in the palne which will be employed throughout the paper. From [3, 10, 11], we can find results concerning many of the basics discussed in section 1 and 2.

신기술을 개발하기 위해서는 다수의 단말기술들이 요구된다. 이 단말기술들은 ${\ulcorner}$SAT${\lrcorner}$ 구조에 의해 구성되는 것이 효율적이며, 이를 통해 다수의 기술컨셉대체안이 도출된다. 그러나, 평가의 투표양식 ( Ballot Form ) 과 ${\ulcorner}$SPN ( System Priority Number )${\lrcorner}$ 를 활용하는 ${\ulcorner}$SAT${\lrcorner}$ 평가방식으로는 평가자의 단편적인 선호도만이 분석가능하며, 투표과정이 번거롭다는 단점이 있다. 이러한 문제 해결을 위해 본 연구에서는 기술컨셉대체안이 요구기능과 실현수단의 순환계층구조로 표현되는 ${\ulcorner}$SAT${\lrcorner}$ 에, 전문기술집단의 선호구조를 정밀히 분석하기 위해 단말기술의 속성변수와 속성수준화를 규정하여 평가하도록 하는 ${\ulcorner}$컨조인트 분석${\lrcorner}$ 을 결합한 ${\ulcorner}$컨조인트 SAT모형 (CJ-SAT Model)${\lrcorner}$ 을 개발하였다.
