This study was performed to evaluate the asbestos exposure levels and variations in textile, brake lining manufacturing and slate manufacturing industries. For this study, fifteen plants of brake lining manufacturing industry, 7 plants of textile industry, and 2 plants of slate manufacturing industry were selected and surveyed. Geometric means (GMs) of airborne asbestos concentrations in textile, brake lining manufacturing, and slate manufacturing industries were 1.42 f/cc(0.07-6.1O f/cc), 0.19 f/cc(<0.01-2.67 f/cc) and 0.08 f/cc(0.02-0.67 f/cc), respectively. In textile industry overall GMs of airborne asbestos concentrations in plants with less than 50 workers and in plants with more than 50 workers were 1.60 f/cc and 0.3 f/cc, respectively. Therefore, the size of plant showed some difference in the airborne asbestos concentrations. Three out of 7(42.9%) exceed the Korean standard, 2 f/cc, and every plant exceed the USA standard, 0.2 f/cc of the OSHA-Permissible Exposure Level(OSHA-PEL). Especially, one plant showed the highest average concentration of 2.87 f/cc. In brake lining manufacturing industry, the plants with less than 50 workers showed 0.22 f/cc. The plants with more than 50 workers showed 0.18 f/cc. All plants showed the exposure level below the Korean standard. Five of 15 (33.3%) were above the OSHA-PEL. One plant showed the highest average concentraton of 0.84 f/cc. In slate manufacturing industry, the average exposure level was 0.08 f/cc, and all of the plants were below the Korean standard and the OSHA-PEL.

A kind of image analysis system is used to investigate the structural features of the papers made from Indian mallow. The screen mark on the paper was identified and analyzed. The dusts, shives and fiber bundles were manifested and calculated. In the aspect of Indian mallow hanji's surface characteristics analyzed by an Image analyzer, the average of gray level and its standard deviation hanji from the woody core were rather lower than of bast fiber pulp because of better sheet formation of the formers. Hower. high brightness hanji showed high value of gray level. The sheet formation and paper opacity were increased with the decrease of standard deviation of gray level. From these results, gray level measurement could be used to predict the paper opacity as well as sheet formation.

본 논문은 통계청에서 실시하는 인구 주택 총조사와 사업체 기초통계조사 시 실시되는 수작업에 의한 표준 산업/직업 코드 분류 시 발생하는 막대한 비용과 시간, 일관성의 결여 등을 해소하기 위한 표준 산업/직업 코드 자동 분류 시스템을 제안한다. 제안한 시스템은 정보 검색 기법과 문서 분류 기법을 이용하여 자연어로 기술된 레코드를 입력 받아 입력 레코드에 해당하는 분류 코드를 생성한다. 수작업으로 올바른 코드가 할당되어 있는 산업 분류 레코드 46,762개와 직업 분류 코드 36,286개를 이용하여 10-fold cross-validation evaluation을 수행한 결과, 제안한 시스템은 완전 자동 모드에서 2수준의 산업 분류에 대해서 87.08%, 5수준에 대해서는 66.08%의 생성률을 보였으며 반자동 모드에서는 각각 99.10%와 92.88%의 성능을 보였다. 직업 분류 코드에 대한 성능은 산업 분류 코드에 대한 성능보다는 약간 저하된 성능을 보였다. 제안한 시스템은 아직 수작업을 완전히 대체할 수 있는 완전 자동 분류기로서는 많은 개선의 여지를 가지고 있지만 수작업을 최소화할 수 있는 반자동 도구나 수작업의 정확도를 검증할 수 있는 보조 도구로써 충분히 활용될 수 있을 것으로 기대된다.

The safety standard for suspended access equipments(SAE) is developed. During the development of the safety standard, consideration was given to a close examination of the standards existing in other industrialized regions and nations such as the Eu.opean Union(EU), the United States, and Japan, as well as the existing domestic safety regulation. Also, a consideration was given to the appraising of the technical level and market conditions of the domestic industry. After careful examination of the current safety practices and issues, it was decided that the standard under development should closely follow those of the EU safety standard. The EU standard provides a detailed account of the calculation methods, safety and stability factors, testing apparatus and procedure, all under unified framework. A number of specific safety requirements have been modified in an effect to properly reflect the difficulties faced by the domestic industry. It is hoped that the safety standard developed here can serve as a valuable tool for policy decisions regarding worker safety.
