  • The differential equations governing both the free vibrations and buckling loads of the beam-columns with constant volumes are derived and solved numerically. The axial load effects are included in the differential equations. The Runge-Kutta method and Regula-Falsi method are used to compute the eigenvalues corresponding to the natural frequencies. and buckling loads. In numerical examples, the simple end constraint is considered.

  • Recently towel cloth has a good prospect as sports wear and out fashion wear. So we will discuss correlational effects between towel cloth quality and it's physical properties. In order to investigate the effect of pile length on the stiffness and absorption of the towel cloth, some experiments have been carried out, and then analyzed by the correlation coefficient.

  • This study examined the effects of depression by household's economic factors with income levels using the wave 1, 2 of Korean Welfare Panel Study. As a result, changes in income satisfaction have significant effects on depression levels. In non-poor households, the income and comsumption expenditure have effects on depression levels. But poor households do not have any effects. Among the control variables, age, marital status, and education level are influential factors on the depression levels. Based on the results, the author was able to recognize the economic factors in household that influnce the depression levels. and The policy directios for household's economic support were discussed.
