金炳美 이화여자대학교 가정대학 의류직물학과 1975 의류직물연구 Vol.- No.5

本 硏究는 各種纖維로 짜여진 몇 가지의 構造가 다른 白色織物을 試料로 하여 이 試驗片을 被驗者가 直接 着用하는 着用試驗과 試驗室에서 一定한 條件으로 人工汚染 시키는 實驗室方法을 通해서 汚染시키고 그 汚染된 試驗片을 洗濯試驗機에서 洗濯하여 纖維種類와 織物構造에 따른 汚染性과 洗濯性을 考察했다. 試料의 織維種類로는 綿纖維를 비롯하여 cellulose系 纖維, 合成纖維를 包含한 6種類이며 織物構造의 種類로는 平織, 綾織으로 나누고 密度 두께 등이 다른 織物 6種類를 試驗片으로 使用하였다. 앞의 方法으로 汚染, 洗濯된 試驗片은 表面反射率을 測定하여 原布, 汚染布, 洗濯布의 反射率의 관계式으로 汚染程度, 汚染效果를 서로 比較하였다. 여기에서 使用된 關係式은 다음과 같다. 이 試驗結果 다음과 같은 事項이 究明되었다. 汚染은 汚染過程에 따라 汚染率, 汚染狀態가 다르다. 汚染이 大氣中에서 이루어질 때는 纖維의 帶電性이 여기에 關係되어 疎水性纖維의 汚染率이 크다. 皮膚와의 摩察과 壓力을 받아 汚染될 때는 吸濕性이 큰 纖維의 汚染率이 크다. 織物의 두께, 密度, 表面狀態가 汚染에 영향을 준다. 卽 織物 두께가 얇고, 密度가 조밀하고, 表面狀態가 매끄러운 것이 汚樂率이 낮다. 洗濯에 있러서는 汚染量이 적을 때 洗濯效率이 높다. 疎水性纖維는 洗濯效率이 높으나 汚染이 깊이 侵透되었을 때는 洗濯效率이 낮아진다. 7. 두께가 얇고 組織이 성근 纖物의 洗濯效率이 높다. It was the aim of this thesis to find out the difference of the soiling properties and soil removal properties in the fiber types and fabric constructions by wearer trials and laboratory tests. Cotton, rayons and synthetie fibers were used as the test specimens of this test in the fiber types, and fabric density, thickness and weaving form were studied in the slde of fabric constructions. The surface reflectances of the original, soiled, and washed specimens were measured to calculate the soil-content of soiled speciemens and washing efficiency of washed specimens br following equations The conclusions of experiments were as the followins. Soil content was different was different according to the soiling process. In the air, the soil content of hydrophobic fibers was high. In the case of soiling by the rubbing to the skin, the sell content of hydrophilic fibers was high. The thin, dense and smooth fabrics showed low soiling content. The washing efficiency was high in the case of low soiling content. The washing efficiency of the hydrophobic fibers was high, but somewhat low in the case of deep penetrating soiling. 7. The washing efficiency of thin and coarse fabrics was high.

The ramie is one of the traditional fabrics produced in Korea for a long time. Especially, ramie produced in Hansan region is famous as Hansan Fine Ramie, because it has finer texture and can be weaved as fine fabric of good quality. It is true that ramie has been produced for a long time and famous, but lack of research made it remain old fashioned and hand worked fabrics of plain weave by conventional hand loom with two harness has been losing its attraction gradually. The purpose of this research is to develop specialized ramie product of good quality and various appearances, keeping the traditional appearance of ramie, which can increase the demand and be exported as traditional Korean fabrics. 1. Production facilities and method must be developed in order to enhance productivity and produce high quality and new fashion goods. 2. "Small quantity and multiple variety" of production must be accomplished. 3. Natural dyeing process must be introduced. 4. QR(Quick Response) system must be adopted in transaction with customer. 5. Planning, investivation, production and marketing must be done in cooperation with industrial, academic world and research institute, and so as to cope with the new situations studies on the ramie should be continually performed.

Objectives : We evaluated the health effects of exposure to BTEX(Benzene, Toluene, Ethylbenzene, m,p-Xylene, o-Xylene) in the Taean area after the Hebei Spirit oil spill. Methods : We used a questionnaire survey to look for health effects among 80 pregnant women 2 to 3 months following the Hebei Spirit oil spill. Their BTEX exposures were estimated using the CALPUFF method. We then used a multiple logistic regression analysis to evaluate the effects of BTEX exposure on the women s health effets. Results : Pregnant women who lived near the accident site reported more symptoms of eye irritation and headache than those who lived farther from the site. There was a trend of decreasing symptoms with an increase in distance from the spill site. Pregnant women exposed to higher ambient cumulative levels of Xylene were significantly more likely to report symptoms of the skin(OR 8.01 95% CI=1.74-36.76) in the first day after the accident and significantly more likely to report abdominal pain(OR 3.86 95% CI=1.02-14.59 for Ethylbenzene, OR 6.70 95% CI=1.82-24.62 for Xylene) during the 1st through 4th days following the accident. Conclusions : This study suggests that exposure to BTEX from an oil spill is correlated with an increased risk of health effects among pregnant women. This implies the need to take proper measures, including the development of a national policy for environmental health emergencies and a plan for studying the short- and long-term chronic health effects associated with such spills.

Purpose Occupational exposure to pesticides is thought to be associated with lung cancer, but studies have yielded conflicting results. We performed a propensity score (PS) based analyses to evaluate the relationship between occupational exposure to pesticides and lung cancer risk in the Korea National Cancer Center community-based cohort study (KNCCCS). Materials and Methods During the follow-up period, 123 incidental lung cancer cases were identified, of the 7,471 subjects in the final statistical analysis. Information about occupational exposure to pesticides and other factors was collected at enrollment (2003-2010). Cox proportional hazards regression analyses were conducted. Four PS-based approaches (i.e., matching, stratification, inverse probability-of-treatment weighting, and the use of the PS as a covariate) were adopted, and the results were compared. PS was obtained from the logistic regression model. Absolute standardized differences according to occupational exposure to pesticides were provided to evaluate the balance in baseline characteristics. Results In the Cox proportional hazards regression model, the hazard ratio (HR) for lung cancer according to occupational exposure to pesticides was 1.82 (95% confidence interval [CI], 1.11 to 2.98). With all the propensity score matching (PSM) methods, the HRs for lung cancer based on exposure to pesticides ranged from 1.65 (95% CI, 1.04 to 2.64) (continuous term with PSM) to 2.84 (95% CI, 1.81 to 4.46) (stratification by 5 strata of the PS). The results varied slightly based on the method used, but the direction and statistical significance remained the same. Conclusion Our results strengthen the evidence for an association between occupational exposure to pesticides and the risk of lung cancer.

Ramie is very comfortable fabric for summer clothes because it has good air-permeability and hygroscopic properties. therefore it has been used as traditional fabrics in Korea since the age of the three Kingdoms. The ramie from Hansan is called Hansan Fine Ramie because it has better qualities as fibers-it can be woven more finely than those from any other region. In spite of its well-known qualities, there thas been so few research work that the ramie industry has been declining for a long time lately. The purpose of this study is to found a basic research about how to make the Hansan ramie developed and competitive in the domestic and foreign market. Bleached and unbleached Hansan ramie fabrics and unbleached chiness ramie were used for this laundry testing samples. The following results were obtained from this experimental study. 1. Chinese ramie fabrics showed highest in tensile stregth and unbleached ramie was higher than bleached. 2. Chinese ramie showed higher than Hansan in stiffness and unbleached Hansan ramie showed highest in ratio of stiffness maintenance by increasing the laundry number of times. 3. Chinese ramie showed lowest in ratio of weight maintenance by increasing the laundry number of times. 4. The ratio of fabric shrinkage showed highest after one time laundry for all the samples, unbleached ramie showed higher shrinkage than bleached by increasing the laundry number of times. 5. Bleached Hansan ramie showed highest in air-permeability, air-permeability was increased in one time's laundry but it was decreased after that.
