Objectives : To investigate the validity of an abbreviated self-rated Korean version of MINI (Mini International Neuropsychiatric Interview) patient health survey which screening social anxiety disorder, panic disorder, generalized anxiety disorder, and major depressive disorder. Methods : 115 subjects completed MINI and MINI patient health survey. The validity of MINI patient health survey was assessed by whether the results from MINI patient health survey were compatible with the results from MINI or not. The Cohen's kappa value, specificity, sensitivity, positive predictive value, and negative predictive value was calculated for this purpose. Results : The Kappa values of social anxiety disorder (0.60), panic disorder (0.49), generalized anxiety disorder (0.60) and major depressive disorder without other co-morbid disorder (0.59) were at least moderate in strength of agreement. Conclusion : The abbreviated self-rated Korean version of MINI patient health survey has the moderate to good validity in social anxiety disorder, panic disorder, generalized anxiety disorder, and major depressive disorder without other co-morbid disorders. Our result suggests that this instrument might be useful for screening above 4 disorders if it is used under careful supervision of experienced clinicians.

Objective: Walking with a Material handling is an activity frequently undertaken by agricultural workers in Korea, due to the nature of their work. This study aimed to investigate differences in biomechanical variables according to the mechanical alignment of the lower limbs when walking with a heavy load, and to use this as basic data in the design of various working environments to reduce the skeletomuscular burden on the knee joint. Method: The study subjects comprised of 22 right-foot dominant adult men and women aged between 20 and 23 years. The subjects were divided into a varus or valgus group according to the mechanical alignment of the lower limb by using radiographic findings. The subjects walked without any load and with a load of 10%, 20%, or 30% of their body weight held in front of them. The Kwon3d XP program was used to calculate biomechanical variables. Results: The flexion/extension moment of the knee joint showed a decreasing trend with increased load, irrespective of the mechanical alignment of the lower limb, while the varus group did not show normal compensatory action when supported by one leg at the point of maximum vertical ground reaction force. In addition, in terms of the time taken, subjects showed no difficulties in one-foot support time up to 20%/BW, but at 30%/BW, despite individual differences, there was an increase in single limb. The increased load resulted in a decrease in the ratio of standing phase to ensure physical stability. The valgus group showed a trend of increasing the stability of their center of mass with increasing load, through higher braking power in the early standing phase. Conclusion: In conclusion, although there was no statistical difference in biomechanical variables according to the mechanical alignment of the lower limbs, the varus group showed a more irregular walking pattern with a Material handling than the valgus group, partially proving the association between lower limb alignment and walking with a Material handling.
