A Study of Dermal and Ocular Exposure to Isocyanate-Based Paints in Crash Repair Workshops
이수길,디노 피사니엘로,이내우,마이클 차카츠크 한국안전학회 2009 한국안전학회지 Vol.24 No.6
Exposure to HDI(hexamethylene di-isocyanate) commonly used in vehicle crash repair workshops remains a leading cause of occupational asthma. Although skin and eye contamination are considered as absorption routes, there are no occupational exposure standards for skin and ocular exposure. This is the reason why there are more empirical data should be provided. Therefore this study was to determine contamination levels of HDI on the skin, eyes, work surfaces, respirators and eye protectors. There was evidence of contamination on a variety of work surfaces, for example, door handles, bench top and spray gun, etc. A high proportion(47~80%) of skin wipe samples from neck, forehead, back hand, palm and wrist was positive for HDI contamination, even though spray time was relatively brief. The contamination levels from spraying inside spray booth were generally higher than outside booth due to poor work practices and inappropriate personal protective use like safety gloves. Apprentices had higher exposure levels than the qualified painters, likely due to lack of the recognition of safety and hygiene. The extent of contamination inside the PPE might provide an indication of the potential for respiratory & skin exposure and ocular exposure. Eye fluid samples from 4 out of 14 workers had the positive detection of HDI contamination, due to poor work practices like no or inappropriate eye protection. Considering the potential for dermal & ocular exposure to contribute to possible health symptoms including respiratory sensitization, the empirical data point to a need for improving work practices and appropriate PPE selection, use and maintenance.

The revitalization of in-bound is a good field of tourist industry which is very important to the development of our economy. The tourist industry of Korea will prosper when she becomes not a country foreign tourists are not willingly to visit again but one they are willingly to visit again fascinated by excellence of her culture. When the events such as ASEM in 2000 and the year of Korea visit in 2001 with the World Cup and the Asian Game in 2002 are held, a folk festival will be well worth seeing to In-Bound Tours. Recently with the introduction of local autonomy system, local economy and culture are emphasized and "Tourism" is being utilized as effective means for its development. There are many problems because our country is still in an early stage of developing a folk festival as tourism goods. The same may be said of Daesaseup-nori of Chonju suggested in this study. Most of the falk festivals are held in beginning of June, which is difficult for people to participate voluntarily and is not helpful to overcome non-high demand season in tourism. It is desirable that various falk festivals should be held all the year round rather than they are concentrated on a specific time. It should be considered even tourists as well as most of the local residents may not participate in interesting events because some festivals are held several places dispersed here and there, and it should be done in perfect order supervised by a local organization. I say nothing of preraring for a guide in a foreign language, the events should have the form or content which is suitable for common people's participation. The development strategies suggested by me was focused on variety of tourism goods for Daesaseup-nori of Chonju, differentiation of goods. Aiming to target market, ordinary opening of main events at easily accessible place, maximization of public relations, the necessity of development of tourism goods and souvenirs for tourists. And I emphasized Korea being as a kind country to visit by improving the conditions of accommodations, civic consciousness and by educating workers in tourist industry. I insisted upon the deposit system of common travel agencies as a strategy for securing financial resources, and stated the establishment of standing performance hall and the operation of a daily tourist train. The about-face of recognition on tourist industry should be established as civic consciousness. The connection between the Chonju area and the area of Baekje culture as strategies of development of tour courses and connection should be reviewed as soon as possible. Finally, I emphasized a FAM TOUR(Familiarization Tour) should be done by analysis of tourists needs as a strategy to attract tourists.

유한요소법은 거의 모든 물리계를 대상으로 특정범위의 해석을 할수있는 방법이며 이에 경계요소법등을 보강하면 각종 센서류등으로만 측정이 가능한 여러가지 고체역학적측정, 유체역학적측정, 전자계적측정 및 물성적측정등을 몇가지의 관련 데이타를 가지고 수행할 수 있는 Tool을 만드는데 주도적 역할을 할 것으로 사료된다. 그리고 실제로 유한요소법을 기초로한 유용한 Simulator들이 실용화되어 있는 실정이며 특히 물성계를 해석하는 Simulator의 개발이 미개척분야로 남아있어 첨단 신소재 개발분야에 대한 연구가 요구된다.
