This thesis is to propose the method of evaluating the validity in stages on the design of a checklist based on the estimate theory of the validity on the design of a checklist and the method of evaluating the validity accordy to the purpose for usiug checklist and establish the standards of estimating the validity in stages on the checklist owing to the estimate theory with the journal, Journal of the Korean Society of Clothing and Textiles. We are emboding the statistical consulting server using the proposed estimate method of the validity and the followings we the questions to solve in future. First, there are many kinds of the statistical methods used in the fields of learing and applied technalogy. So we must establish the statistical standars required in each field and study and develope the special statistical checklists. Second, it is neded to systemize the estimate methods and standard on the validity by building the statistical consult DB, evaluate the researchers according to the degrees of statistical knowledge the validity of study design iud propose the delicate and generalized statistical methods appropriate to the ability of researchers.

N/A The chromosome behavior and it`s synapsis in the meiosis of pollen mother cell were studied on Populus alba L. as a female parent tree, Populus glandulosa Uyeki as a male parent tree and their hybrid, Populus alba x glandulosa. 1. At metaphase I, the number of nuclear plates with early separation chromosome were observed with the lowest proportion of 11.0% in Populus glandulosa and with the highest proportion of 13.0% in Populus alba x glandulosa. 2. At metaphase II, early separation chromosomes appeared with the frequency of 11.0% in Populus alba x glandulosa. But the frequency was not different with those of the parental trees. 3. At anaphase I, lagging chromosomes appeared with some high rate of 11.6% in Populus alba x glandulosa and yet the number of chromosome bridges in populus alba x glandulosa almost were not different with the partental trees. 4. At anaphase II, lagging chromosomes appeared with some high frequency of 10.2% in Populus alba x glandulosa and the chromosome bridges in Populus glandulosa appeared with the highest frequency in all studied trees. 5. The frequency of abnormal pollen sporad was the highest value of 8.2% in Populus alba x glandulosa among the studied trees. With the results, it might be assured that the chromosome segregation and it`s synapsis behaved normally in Populus alba, Populus glandulosa and Populus alba x glandulosa, and so all the studied trees could produced normal pollens.
