This work aims to measure the leakage of the personal protective equipment by using the fluorescent aerosol tracer. The fluorescent aerosols were employed as airborne particulates in a controlled chamber with ultraviolet (UV) light-detectable stickers. After an exposure and leakage test, the protective equipment was removed and photographed with UV-scanning to evaluate areas and color depth ratio of the areas where fluorescent aerosols had adhered to the body through the protective equipment. An image processor installed with an entropy-based algorithm was developed to segment the fluorescent area and calculate its relative leakage ratio (Lr) in real time. This study shows that the total leakage rate of the K brand protective clothing is 2.04 × 10-4 in two repetitions, and its 10- repetition total leakage rate is about 3.15×10-3. The two-repetition total leakage rate of the P brand protective clothing is about 2.47×10-4, and its 10 repetition total leakage rate is about 4.79×10-3. The two-repetition total leakage rate of the W brand protective clothing is about 1.04×10-4, and its 10-repetition total leakage rate is about 4.68×10-3.

The worsening impact of piracy in recent years, downloadable content system is the current trend to against Piracy. The main purpose of the study download content elements, can effectively provide attractive of content, the downloadable content to enter a more competitive edge. Its elements of the downloadable content will be different. This study places the focus on the use of network-level analysis (ANP) decision support tools, different elements of the downloadable content systems effectiveness in the fight against piracy analysis of case studies. The combination of network-level analysis-based approach, this paper can provide game publishers with the method of downloadable content production, realistic, and accurately in the selection of downloadable content system.
