This study was conducted to identify components of thinners and to evaluate worker´s exposure to them in an auto manufacturing plant. Main components including Ethylene Glycol Ether were analyzed quantitatively as well as qualitatively. More than 18 components were analyzed qualitatively in 12 thinner samples. Toluene was the most frequently detected, and its amount ranged from 8.5% to 62.5%. 11 of 12 thinner samples have EGEE, EGEEA, and EGBE named Ethylene Glycol Ether. 23.7% of EGEE was included in C sample and 3.3 % in G sample. EGEEA was detected to 7.3% in D sample, and lower than 2.6 % in other 6 samples. Amount of EGBE was as much as 25.9% in G sample, 19.6% in E sample, 14.6% in A sample, and 11.3% in C sample. In addition to these components, a little amount of several components such as ketone, alchol, ether, and ester were also detected. But all thinner samples have not included benzene. Mixing room shows the highest concentration. Of several material included in thinner, worker´s exposure to toluene was 12.9 ppm in mixing room, and 3.3 ppm in third room which were higher than other components. Ethylene Glycol Ether detected in air was only EGEEA. Frequency of EGEEA detected in the air was as much as 90% in the mixing room and 40% in the third room. Worker´s average exposure to EGEEA was 2.4 ppm lower than TLV(5 ppm). In order to evaluate worker´s exposure in process using thinner, air sample to analyze toluene, xylene, benzene, Ethylene Glycol Ether, MIBK must be taken

India is a new and popular marker for doing businesses. According to the Kotra and Samsung Economy Research Center, 40% of demands in India hold watch market and it occupies the top. With this data, this research chooses India for the proper market and to deal with unexpected situations, a new brand, Veritas, starts the business directly. In more depth, to enter the foreign market, this research is based on SWOT Strategy, STP, 4P and other marketing thesis. For the final strategies, this research focuses on weaknesses and threats. These points will be solved by the researcher's suggestions. Concretely, because of the special quality of the target market, India, researchers will focus on cultures and religions to develop business strategies. Furthermore, both of localization and globalization will be used.
