In this study, From 1,560 entry-level of TOPIK standard vocabularies are 702 Sino-Korean words selected which account for 45% of the whole vocabularies in TOPIK. In addition, the same form and morpheme words in Sino-Korean are sorted out by comparing them with 5,000 words of the NEW HSK vocabularies in Sino-Korean morpheme, array position of morpheme, meaning, and usage. Those are categorized into three parts : type of completely the same form-morpheme and same meaning, use, class(189 pairs), type of completely the same form-morpheme and partly same meaning, use, class(28 pairs), and type of completely the same form-morpheme and different meaning, use, class(10 pairs). The first type of words that account for 83.26% of them are used in exactly the same way in both Chinese and Korean. Through an accurate understanding of these vocabularies could either Chinese-speaking Korean learners or Korean-speaking Chinese learners apply those words in their mother tongue to the acquisition of the target language and get more effective means of learning methods for language proficiency test.

This paper presents a general description of single and dual contact tooling systems, finite element analysis, and discussions on the application of the system to the 5-head router machine which is in particular for aerospace components. This study has been performed as part of the development of the new generation 5-head router machine which is designed for high productivity. Such high productivity in essence requires high speed rotation and multiple spindles in one machine. The high speed rotation may exceed a range in a conventional single contact tooling system. The conventional tooling system is reevaluated in comparison with the dual-contact system. Finite element analysis using simplified spindle models compares major differences in the two systems. Some problems in the application to the 5-head router machine are discussed.
