An automobile outside rearview mirror system has been analyzed and designed, to reduce the vibration, A finite element model is defined for the analysis with a commercial software. Modal analysis has been conducted for the calculation of natural frequencies. Harmonic analysis is utilized to estimate the displacements of the glass surface under dynamic loads, the model is verified with the vibration experiment for parts and the assembled body.<br/> The structure of the mirror system has been optimized for the robustness defined by the Taguchi concept. At first, many design variables are identified. Input design variables are selected due to the amount of contribution, the SN ratio in the Taguchi method is replaced by an objective function with mean and standard deviation, the defined objective function is appropriate in the structural design. The selected design minimized the vibration which it is insensitive to noise.<br/>

The outside rearview mirror system is analyzed and designed to cnhance the vibrational behavior. The sensitivity information is utilized for the selection of design variables which are important in the bhavior of mirror system. With selected design variables, designs are determined using an orthogonal array and structural optimization approach. Also, the comparison test is carried out between the solutions of the orthogonal array method and the structural optimization.<br/>

General structure consists of parts and joints. These days. the structures are designed computationally by structural optimization. which uses the finite element analysis. It is very difficult to design<br/> structure with many parts because of the complexity. A jot of resources must be invested regardless of the reliability of solution. The large scale structures are simplified for the design purpose. At first. a simplified mode] is defined to include the behaviors of the large scale structure. The details of the those of the original mode1. Optimization methods are utilized for the matching process. The suggested method is verified through various examples. The method is very effective in designing large scale structures.

(Purpose) This study aims to find ways in establishing and utilizing a cooperative network between the HRDK, domestic and foreign institutions operating in Canada to revitalize overseas employment in Canada, and further advance overseas employment using local overseas organizations. (Design/methodology/approach) This study intended to analyze, the operation status of each institution and overseas employment projects to establish a cooperative network with the HRDK, local domestic and foreign public and private institutions to revitalize the overseas expansion of Korean youth in Vancouver, Canada. For the analysis of this study, from November 10, 2021 to December 3, 2022, as public institutions: HRDK, Embassy of Canada to Korea, KOTRA Vancouver, Vancouver Korean and local Businesses, OKTA, Korea Small Business Trade of Vancouver, and Korean Workers in Canada were interviewed. (Findings) Overseas employment activities in Vancouver, Canada are led by the KOTRA Vancourver, HRDK, and World Korean Trade Association (OKTA). For overseas employment in Vancouver, Canada, Vancouver K-Move Center, and the World Korean Trade Association (OKTA) are leading overseas employment projects. In addition, Emigration Corp, Korean Small Business Trade of Vancouver, Korean and local businesses, Canadian local agencies and training institutes, and OKTA Vancouver branch support overseas employment agencies to form cooperative relationships. (Research implications or Originality) As a result of this study, it is necessary to systematize efficient overseas employment support projects by establishing a cooperative network system with the HRDK and overseas employment institutions. In addition, it is necessary to strengthen the recruitment information collection, life counseling, and job placement system for unemployed people through flexible cooperation with the Korean Association in Canada. In particular, it is necessary to form an alumni association for overseas employees in Canada to activate mentor programs and establish a database of employed people. Finally, if a job seeker succeeds in finding a job in Canada but returns to Korea due to visa expiration, a support system should be established to help in securing a job successfully in Korea.
