This study selected clothing materials that are frequently used in summer season. These are 100% ramie, ramie / cotton, ramie polyester, and ramie / rayon. With these materials, the writer analysed their shrinkage rate from laundering and dry-cleaning. The results are as followings. 1. The Shrinkage Rate as the number of laundering. The shrinkage rate from the first time of laundering the above 4 materials showed the greatest increasing amount on their warp and weft. And then repeated laundering showed a little difference in shrinkage rate. 2. The Shrinkage Rate was generally greater in the warp than in the waft. 3. The Shrinkage Rate was Shown Within 0.7% from the first Drycleaning. And, after that another time of laundering showed less shrinkage rate than the case of laundering only, but repeated laundering showed little difference. 4. The Differences of Shrinkage in the Materials. 100% Ramie showed the greatest change and then ramie / cotton the second, ramie / rayon the third, and ramie / polyster showed the least shrinkage rate.

A numerical study was performed to investigate characteristics of one-dimensional consolidation of soft clay. Results of consolidation tests with the remolded normally consolidation clay of having a very high initial void ratio were analyzed by using the numerical technique of finite difference method based on the finite strain consolidation theory, to evaluate consolidational characteristics of soft clay under surcharges on the top of clay. On the other hand, a numerical parametric study on soft clay consolidated due to its self-weight was also carried out to find its effect on one-dimensional consolidation. Terzaghi's conventional consolidation theory, finite strain consolidation theories with linear and non-linear interpolation of effective stress-void ratio -permeability realtion were used to analyze the test results and their results were compared to each other to figure out the difference between them.Therefore, the validity of theories was assessed.

In order to determine acetylcholine and choline in the biological samples, the specific enzymes of acetylcholinesterase (AChE) and choline oxidase (ChO), which utilize acetylcholine and choline as substrates, were employed to convert substrates to H2O2. The produced H2O2 was coupled to 4-aminoantipyrine/phenol with peroxidase (PO) yielding quinoneimine dye which was measured at 508 nm. In the present enzymatic spectrophotometric analysis the product at the equilibrium state was measured considering accuracy, precision, time and cost of the analysis. The developed analytical method yielded good linearity (calibration curve; A508=9534[acetylcholine]+0.009, correlation coefficient (R2); 0.999) with detection limit of 1.11×10-7 M, reasonable precision (relative standard deviation; 0.10~1.62% at 2.5×10-6 M~1.25×10-4 M) and accuracy (relative error; -0.24~0.97% at 4.13×10-6M~1.01×10-4 M) for acetylcholine chloride standard solution. The concentrations of acetylcholine and choline in human serum were found as 3.20×10-5 M and 1.14×10-4 M, respectively. The brain tissues of Sprague-Dawley strain rat contained 9.82 μg/g of acetylcholine and 6.53 μg/g of choline in the cerebrum, while 7.37 μg/g of acetylcholine and 5.34 μg/g of choline in the cerebellum.

The patients with various ocular diseases frequently rub their eyes. The author studied the effects of eye rubbing on the histologic characteristics cf the conjunctiva. Each one eye of twenty albino rabbits were rubbed on the upper lid with finger for five-minute period, and the unrubbed contralateral eye served as a control. The upper tarsal conjunctivas were taken immediately, at four. eight, and twenty-four hours after the rubbing. After fixation of specimens in Kernovsky's fixative, the tissues were processed for preparation of Epon block and one-micron section. Sections were stained with alkaline Giemsa and toluidine blue arid light microscopic examination was performed. The results were as followings : Immediately after rubbing, the conjunctival epithelium was disrupted and the mast cells became degranulation. At four hours, there was moderate infiltration of neutrophils. At eight arid twenty-four hours after rubbing, infiltration of macrophages was occurred and increased in cumber. But there was no significant changes in numbers of lymphocytes, plasma cells, and eosinophils. This study revealed that eye rubbing induces conjunctival erythema and alteration in the inflammatory cell infiltrate, and therefore eye rubbing map influence the course and severity of ocular diseases.
