CAD/CAM의 초보지식을 부분적이나마 간략히 소개해 보았다. CAD/CAM에서 기하형상기술이 차지하는 비중과 이 기술의 한계점을 논의해 보았고, 설계에서 필수인 설계 지식이 CAD시스템에 융합되기 어려움을 실제의 예를들어 소개해 보았다. 마지막으로 현재의 CAD시스템이 기계전체 차원에서의 설계 도구이기보다 부품설계 차원에서의 도구임을 알아보았다. 현재까지 CAD시스 템이 설계과정에서 별로 창의력이 요구되지 않는, 그렇지만 많은 시간이 소요되는 도면 작업을 간편화하게 한 것으로도 CAD가 설계자동화에 큰 몫을 담당해 왔다고 볼 수 있다. 앞으로 미래의 CAD 방향은 인간의 창의력을 도와주는 곳으로 나가야함을 자명한 사실이라 본다.

In establishing regional industrial policies, it is important to understand the clustering structure of regional industries. In particular, in order to promote a smart specialization strategy that establishes a growth strategy that reflects regional characteristics, the degree of specialization and diversification of the regional industry must be simultaneously identified. The related variety index, which has been widely used in the past, measures the degree of diversification of related industries on a regional basis and explains the macroscopic structure of regional industries. However, through regional analysis, it was impossible to identify specialized areas within a region where various industries are concentrated and to determine the degree of diversification within specialized industries. Accordingly, this study proposed Scope Cluster Index, which measures the related variety index at the level of regional manufacturing industries and measures the relative level compared to the national level, as an indicator for regional industrial structure analysis. Scope Cluster Index indicates the level of horizontal agglomeration of related industries in a region compared to the national level. The Scope Cluster Index has a value greater than 1 as the value chain of the region's key industries is more balanced and diversified compared to the national average. This study divided the regional industrial structure into four types based on the Scale Cluster Index based on the Location coefficient and the newly proposed Scope Cluster Index as two axes. This study applied the indicators and type classifications proposed above to the manufacturing industry in the Southeast region to determine the degree of diversification of regional industries by industry type and analyzed the different agglomeration structures by regional manufacturing industry. In addition, the relationship between Scope Cluster Index and the performance of local industries was found to be positive(+). This study concludes by presenting a regional development strategy that can be derived as a result of applying the Scope Cluster Index to the southeastern region's manufacturing industry and discussing the usefulness and limitations of the Scope Cluster Index.
