The procedure to prepare an acrylic emulsion water repellents by blending of arcylic copolymer, activated polyethylene, wax, and emulsifiers was published in the previous paper. After the treatment of the prepared water repellents on a cotton fabrics with and without textile finishing resin, washability, contact angle, tearing strength, and crease recovery were tested. As the result, there were remarkable improvements in physical properties. Proper curing temperature of the synthesized water repellents impellents was 150℃ : proper using concentration was 5wt% : sodium acetate was the best catalyst for water repellents among the used, and proper concentration was 1.0wt%.

Purpose: To study characteristics of bicycle and motorcycle injured patients in a university hospital and in an edited national injury surveillance report. Methods: Between July 2007 and January 2010, we collected data on bicycle and motorcycle injured patients in a university hospital. First, we compared the characteristics of each group. Second, we analyzed injury severity using their injury severity score (ISS) and their revised trauma score (RTS). We compared the categories of an edited national injury surveillance report with our university-acquired data. Results: The total number of patients in traffic accidents was 4,111 (including 204 bicycle riders and 165 motorcycle riders). For those in bicycle accidents, a large fraction was < 10 years old or > 51 years old. For those in motorcycle accidents. Those in motorcycle accidents had an increased proportion of liver cirrhosis and of previous experience with a similar accident. Bicycle accidents had a higher proportion of cases where just the driver or just the passenger was injured. Just falling was the most cause of injury. Others were injured by collision with a car or by both. Motorcycle riders who wore helmets were better protected. Most accidents occurred after 19:00: motorcycle accidents most frequently between 0:00 and 7:00 and between 13:00 and 18:00 hours. Injury severity score were not different. Admission to the hospital and fatalities were highest for motorcycle accidents. The place of injury and alcohol intoxication status were reported for traffic accidents. Conclusion: Bicycle and motorcycle injuries were already considered as important factors in traffic accidents included in the injury surveillance report. More factors, including age,time, past history, etc. should be added.

Spin finish(NSFs) for synthetic fiber were prepared. NSF-3 was proved to be the best spin finish by testing the properties and emulsion stability, etc. of NSFs. NSF-3 prepared by blending of spindle oil 70g, paraffin wax 10g, glyceryl mono-oleate 5g, POE(10) nonylphenyl ether 4g, POE(20) sorbitan tri-oleate 4g, Na-dioctyl sulfosuccinate 4g, antistatic agent 2g and water 1g was excellent in its characteristics. Optimum physical conditions of nylon filament treated with NSF-3 according to the number of revolution of oil roller were obtained at conditions of 5.5rpm in the number of revolution of oil roller, 1.21% of oil pick up, and denier 69.2D.
