  • This paper presents a very simple procedure for determining the sensitivities of the eigenpairs of damped vibratory system with distinct eigenvalues. The eigenpairs derivatives can be obtained by solving algebraic equation with a symmetric coefficient matrix whose order is (n+1) ${\times}$ (n+1), where n is the number of degree of freedom the mothod is an improvement of recent work by I. W. Lee, D. O. Kim and G. H. Jung; the key idea is that the eigenvalue derivatives and the eigenvector derivatives are obtained at once via only one algebraic equation, instead of using two equations separately as like in Lee and Jung's method. Of course, the method preserves the advantages of Lee and Jung's method.

  • The purpose of this study was to identify the associations between Lee Je-ma Sasang Constitutions and C. G. Jung's Psychological Types. In addition, this information could also be valuable in clinical practices. The QSCC II(Questionnaire for Sasang Constitution Classification II) and MBTI(Myers-Briggs Type Indicator) was administered to 319 volunteer male soldiers($21.5{\pm}1.4yr$) in the army. The results were as follows; 1) Soyangin groups tended to be extroverted, sensing, perceiving types. 2) Soeumin groups tended to be introverted, sensing, thinking, perceiving types. 3) Taeumin groups tended to be extroverted, sensing, thinking types. 4) but, there were no Taeyang groups according to QSCC II. This results show that there are significant relationships between Lee Je-ma sasang constitutions and C. G. Jung's psychological types.
