The effect of the secondary superficial air velocity on the elutriation rate of fines were investigated ina cold model of two-stage swirl-flow fluidized bed. The elutriation rates of fluidized particles were measured. And entrainment rates of particles were measured along the freeboard height in the single stage fluidized bed. As a result, the initial entrainment rates of the particles at the bed surface were calulated. The entrainment rate of the particles exponentially decreased as the height of freeboard was increased. The decay constant was almost inversly proportional to the superficial air velocity. The initial entrainment rate of particles depended on the excess air velocity to the power of 1.6. As the secondary air superficial velocity increased the elutriation rates of the particles maintained low values until the secondary air superficial velocity reached to 0.3m/s. When the secoandry air superficial velocity exceeded 0.3m/s, the elutriation rate of the particles increased sharply. By the increment of the secondary air superficial velocity, solid loading was increased and swirl intensity was decreased in the upper stage freeboard. Due to this combined effects, the elutriation rate of the particles increased sharply. However, the trapping rate of the particles in the upper stage freeboard showed high values above 97% in whole rage of the secondary air superficial velocity.

Principal component analysis and Multiple regression method were applied, for the assessment of health related fitness age(more frequently term the biological age), to the data for 11 physical fitness and anthropometric variables. Subjects were 200 Korean men, aged 20 to 63 years, who were recruited in a series of tests for physical fitness and anthropometry. Analyses of the data revealed that, out of the 11 variables examined, 6 variables were suitable for the assessment of health related fitness age, and that the subjects were approximately 5 years younger when compared to their chronological age. The developed equation for the estimation of health related fitness age(HFA) was HFA = 69.151 -0.146X_1,-0.055X_2-0.678X_3-13.784X_4-0.463X_5-0.054X_6; where X_1=VO_2max(㎖/㎏/min), X_2 = trunk flexion(㎝), X_3 = Sit-ups, X_4 = whole body reaction time(sec), X_5 = vertical jump(㎝), and X_6 = one foot balance with eyes closed(sec). Since independent variables of this equation included health related physical fitness, we defined the score obtained from the equation as "health related fitness age(HFA)" .The equation of HFA was considered useful for evaluating ability of health re lated fitness in adulthood.
