This study is to examine the changes in clothing hygiene mentioned in Korea newspapers issued for modern centennial when the rapidly changing circumstances had occurred. The research of the costume history is rather well established, however the consumer behavior of wearers have been rare studied. Therefore, we determined the wearing or using behavior of textile users by social changes according to the current of times, as newspapers reveal social environments in those days. All articles related the subject were collected from The Donga Daily News, Chosun Daily News and Maeil Sinbo and analysed and categorized by the contents. The results are as follow: 1. There were 137 articles in the Maeil Shinbo, 123 in the Donga Ilbo, and 162 in the Chosun Ilbo. Whole articles were categorized into clothing hygiene, clothing comfort, and miscellaneous textile products. There were more articles mentioned on clothing hygiene than on clothing comfort. Apparel improvement was emphasized by the social reformation before 1945. 2. The major contents of clothing hygiene was concentrated on clothing damage by moth, fungi and microorganisms or odor from the unwashed clothes during the storage in the rainy summer season. While, clothing comfort was focused on comfortable wearing methods for keeping warmth in the cold winter season. 3. More articles appeared in summer and winter. The majority of articles were about sterilization and disinfection of damaged clothes by microorganisms during clothing maintenance in summer, and enhancement of physical strength by wearing control with thermal comfort in winter. 4. Growth of textile industry, improvement in living circumstance, economic development were closely related to the clothing hygiene and clothing comfort.

The purpose of this research was to analyze the residual water retention and to determine the number and species of microorganisms from the wet cotton fabrics in dehydration and drying process during washing. The drying rates of terrycloth and interlock knit under the rainy seasons were measured according to the dehydration and hanging methods, layers of fabric and pre-treatment agents. Microorganisms were isolated from the dried terrycloth by pure culture, and were identified by Biolog system. The results are as follow: The initial water retentions of fabrics after dehydration decreased in the order of dripping>centrifuge>squeezing method, which affected the drying rate. The drying rates were faster by increasing surface area of fabrics. There was no significant difference in drying rate among the fabrics pre-treated with detergent, or fabric softener, or cationic surfactants such as Cetyltrimethylammonium bromide(CTAB) and Benzalkonium chloride(BC). Puedomonas aureginosa was found in the fabrics treated with a powder-type detergent. On the other side, there was no growth of microorganism in the fabrics treated with a liquid-type detergent (containing antibacterial agent), CTAB and BC.

김명자,최승귀 淑明女子大學校 1988 論文集 Vol.29 No.-

The behavior of microemulsions formed with fatty acid soap, medium chain length alcohol, hydrocarbon, and water was studied as a function of alkyl chain length of surfactant, alcohol, and oil, and also as a function of the positional isomer of alcohol, in order to test chain length compatibility effect in microemulsion formation. In the present study, the properties of the microemulsions were investigated by phase diagrams which were obtained by titration method, and also by electrical resistance, viscosity, and surface tension measurements performed throughout the course of microemulsion formation and solubilization. For 1-pentanol as cosurfactant, water solubilization reached a maximum when the oil chain length plus that of alcohol was equal to that of the surfactant, and this result suggested the validity of alkyl chain compatibility effect in microemulsion formation. Maximum solubilization of water decr ased as the position of hydroxyl group in pentanol varied from 1- to 3- pentanol, and alkyl chain compatibility was not observed in the case of 2- and 3- pentanol. Given these facts, nature and mechanism of microemulsion formation were proposed to give some insight into its application to cosmetics.

The distribution of boron on 98 different species of woody landscape plants which belonged to 38 different families were investigated. The soils used were Daegu Series developed out of Residiuum of Shale which is commonly found in Bongduk-dong, Daegu City and Hayang-eup, Kyungsan-gun, Kyungpllk Province. Some of the results obtained are summerized as follows : 1. Among the tested palnts, 33 species including European holly contained comparatively ow level of boron and 53 ones such as apple tree required medium level of boron for the normal growth. On the contrary, the rest of 9 species including Manshurian fullmoon maple accumulated much high level of boron for the normal growth. 2. Among the tested plants, tree of heaven contained the highest level of boron(90.4±0.15ppm) while arrow bamboo contained the lowest one(5.3±0.79ppm) 3. No significant correlation between the single leaf area and the boron content of the leaves was recognized when the area of the single leaf is less than 100㎠ but highly significant correlation(r=0.769**) between above two characters was recognized when that is over 100㎠/leaf. 4. when the tested plants were classified by the content of boron in the leaves, the rate of plants having the contents of 5∼10ppm, 10∼20ppm, 20∼30ppm, 30∼40ppm, 40∼50ppm, 50∼60ppm, and over 60ppm were 1%, 35.8%, 29.6%, 23.5%, 5.1%, 2.0%, and 3.0% respectively. 5. No significant correlation(r=0.072) between the content of boron in the soils naturally developed out of Shale and the content of boron in the leaves tested was recognized.
