This is a pity, because decision making is a truly in dispensable process. But pity or not, our ignorance is a fact. We do, of course, know a good deal about the steps wich managers have found to be helpful as prerequisites for making decitions. So we will, in this paper, study on the subject.

Direct tensile test technique was used for specimens with enlarged ends to which load was applied purely by friction using four kinds of lazy tongs grips. 1. The experimental value of strength shows a probability distribution quite close to the straight line when plotted either on Weibull probability papers or on normal ones. 2. Compressive strengths of prism and cylinder specimens show the maximum values at S=10.0cm, and decreases gradually when size specimens larger in the range where S is larger than 10cm. 3. The value of coefficient of variation CV of concrete strength increases greatly with decrease in S in the range where prism width S is 4.46-7.25 and cylinder diameters S (D) is 7.5-10.0. 4. The value of CV of prism and cylinder strength increases greatly with decrease in D/d in the range where D/d is less than 4. The size of model specimen D and size of aggregate d should be used in the range where D/d is larger than 4-5 in the tests of concrete models.

A dense hot plasma is produced in high pressure argon gass, and a radiation emitted from the laser plasma is spectroscopically analysed. The radiation has line spectrum of Ar I and Ar II with continuous spectrum. Improving the electric power source circuit, the laser output power is stabilized and the scatter in measured values is reduced. The plasma temperature is determined from the line intensity ratio of Ar II over the wide pressure range up ot 100 atm. The plasma temperature increases with increase of pressure, but the dependence of the temperature on pressure is weak. The plasma temperature obtained in this work is order of 10eV, which is reasonable from the result in other paper at atmospheric pressure. The plasma temperature is also determined from continuous spectrum and energy balance.
