This study is an empirical research to find out the effect on the management performance of hidden champions of food manufacturing companies when using blue ocean strategy for new product development. In order to achieve the purpose of this study, we conducted a questionnaire survey on hidden champions in the domestic food manufacturing industry and proceeded empirical analysis. When small and medium-sized enterprises in food manufacturing industries develop a new product, searching for non-customer, rebuilding the market boundary, and linking the external networks have a significant impact on their management performance. However, the fair procedure did not have a significant effect on the management performance. In terms of relative influence, rebuilding the market boundary was most affecting, followed by searching for non-customer and linking the external networks. On the other hand, this study implicated the management performance of hidden champions of food manufacturing industries when new products is developed by using the blue ocean strategy. Obtained results are as follows. If small and medium-sized enterprises of food manufacturing industries develop new products, it will be able to improve the management performance by utilizing strategies such as searching for non-customer, rebuilding the market boundary, and linking the external networks. In particular, the rebuilding the market boundary among the blue ocean strategies has a relatively high impact on management performance.

본 연구에서는 비국지 탄성이론과 미분변환법을 이용하여 탄성매질속 다중 크랙을 가진 비균질 나노빔의 지배방정식을 유도하고, 유도된 지배방정식과 경계조건에 미분변환법을 적용하여 나노빔의 축방향의 진동해석을 하며, 나노빔의 첫단과 끝단의 경계조건이 각각 고정 단(Clamped end)과 자유단(Free end)의 경우에 대하여 수치해석을 수행하였다. 수치해석 결과를 기존 연구결과와 비교하여 타당성을 입증한 후, 비국지 작은 척도효과 (Nonlocal small scale effect), 탄성매질의 강성, 크랙의 위치, 크랙의 강성 그리고 비국지 탄성이론의 나노빔에 대한 진동해석 결과를 고찰하였다.
