The purpose of this research was to analysis compounds of unpleasant odor from the cotton fabrics in dehydration and drying process during washing. The cotton fabrics were treated with various commercial detergents and fabric softener of cationic surfactants such as Cetyltrimethylammonium bromide(CTAB) and Benzalkonium chloride(BC), then dehydrated and dried. The compounds of odor impregnated in fabric were detected by using GC-MS. The results are as follows: The fabrics treated with a powder-type detergent, CTAB and BC gave out compounds unpleasant odor. n-Butyraldehyde and isobutyaldehyde produced during microorganism growth were revealed as source of the compounds of the unpleasant odor. However, no aldehydes were detected from the fabrics treated with commercial fabric softener which seems to act as a deodorizer.

Compared with synthetic dyes, natural dyes have inferior colorfastness as a result of the exposure of the material to any environment that may be encountered during the processing, testing, storage, display or use of the dyed materials. Especially, colors on fabrics fade excessively in the sunlight and after washing. Therefore, it is problem to make the practical and commercial textile products with natural-dyed fabrics. Therefore, the object of this study is to analyse the factors affected to colorfastness during washing and wearing under sunlight. In experimental, fifteen natural dyes were dyed by the Korean traditional dyeing methods onto natural fiber fabrics: cotton, silk, ramie, and flex. Total 49 dyed fabrics in combination with dyes and fibers were used for the specimen. The Launder-Ometer was used for evaluating the effects of exposure to repeated washing from 1 to 50 washing cycles (KS K 0430). The test fabrics were exposed to the D65 artificial light source in Weather-O-Meter enclosed Carbon-arc lamp for 5 to 120 hours (KS K 0700). Color difference(ΔE) in the CIEL*A*B* color-order system were determined by spectrophotometer at 10°observer. Light and washing caused significant changes in the color of natural-dyed fabrics. The degree and nature of color changes on the fabrics were dependent on the combination of fiber and the dye type used. The groups of violet(Lithospermum erythrorhizon Sieb.et Zucc.) and black color(Ailanthus altissima Swingle, Phus trichocarpa Miq) yielded excellent colorfastness to light and repeated washing. The group of indigo blue color(Polygonum tinctorium Lour.) was also very resistant to fading in both exposure except silk. Whereas the dye groups of Red, Yellow, Orange, Brown colors indicated greatest changes in fading, particularly Carthamus tinctorius L.

his study was conducted to analyze the dental care status in the rural residents. An interview and questionnaire survey wacarried out for 864 people who 1ived in Kumryung-gun, Kyung -sangpook - do, from February 1 to March 30, 1990. The summarized resul ts are as follows : The rate of persons who experienced the dento - facial discom-forts during 1 year and it was hightest in the age group of 10-19. During 1 year period, 82.6 % of the cases had treated the per-ceived dento -facial discomforts, 17.4 % had done no action. 39.4 % had treated experienced oral disease at communi ty health and center or subcenter, 23.3 % had treated at dental clinics and 9.3 % had treated by the unauthorized illegally.

A Study on the Anomalies Prevalance of Permenant Teeth by Plaster Model Analysis This study was designed to find out the prevalance dental anomalies. the suvey was undertaken of 201 college students (male: 134, femle:67) at age from 18 to 27 years and statistical analysis was made. The results were as follows: 1. The prevalence of individual dental anomalies were as follows: congenital missing teeth 10.4%, supernumerary teeth 1.5%, fused teeth 0.5%. peg lateralis 6.5%. anomalies of mandibular molar 6.0%, high canine 8.5%, malposed teeth 24.9%. 2. In congenitally missing teeth, the mandibular right lateral incisor showed the highest rate of the prevalence (2.5%), the prevalence of the congenital missing of 3rd molar was 75.6%, maxillary was more than higer mandible( p <0.05, p <0.01 ). 3. The prevalence of the peg lateralis was higher in female than male. 4. The prevalence of the malposed teeth was 0.5%-4.0% the mandibular left second premolar was the highest rate of the prevalance(4.0%). 5. The prevalence of the high canine was higher in female , in right.
