In seeking further efficiency in production preparation, it is common to examine assembly sequences using digital manufacturing. The assembly sequences affect the product evaluation, so it is necessary to test several assembly sequences before actual production. However, because selection and testing of assembly sequences depends on the operator's personal experience and intuition, only a small number of assembly sequences are actually tested. Nevertheless, there is a systematic method for generating assembly sequences using a contact-related figure. However, the larger the number of parts, the larger the number of assembly sequences geometric becomes. The purpose of this study is to establish a systematic method of generating efficient assembly sequences regardless of the number of parts. To generate such assembly sequences selectively, a "Tournament Tree," which shows the structure of an assembly sequence, is formulated. Applying the method to assembly sequences of a water valve, good assembly sequences with the same structure as the Tournament Tree are identified. The structure of such a Tournament Tree tends to have fewer steps than the others. As a test, the structure is then applied for a drum cartridge with 38 parts. In all the assembly sequences generated from the contact-related figures, the best assembly sequence is generated by using the Tournament Tree.

A South Korea master craftsman had the best technology that oneself and others are certified in various fields. ChoSeokJin coach has continued the lifeline of the Korean wood furniture Jeonbuk region. It is already famous coach to award-winning Olympic coach and tournament of the world. Check his mental world and his life through the work of ChoSeokJin coach. Through a harsh process until the Republic of Korea master craftsman, it was an opportunity to reaffirm once again the importance of effort and commitment. South Korea wood chief coach (the field of furniture) growth phase of the No. 1 ChoSeokJin coach, Ripe stage and spirit such as through his neck furniture fabrication methods, he is him then and the situation until the coach and the intangible cultural heritage had asked We look at the world. The work of ChoSeokJin coach by research analysis separately in the previous fiscal year and late, his hope and neck that is a topic that has been internalized "I want wings that can over time attach to a tree." In his work We understand the passion for furniture.
