Methods: A cross-sectional study was conducted among IFFWs sampled from several joint- venture and private factories in Dongguan city. Results: Out of 175 sampled workers, 165 qualified for inclusion and the median age was 22. The results showed that the IFFWs had low levels of knowledge about HIV/AIDS, and held many misconceptions. Thirty three of 76 (43.4%) unmarried IFFWs had premarital sexual contact, and more than half of these contacts were one-night stands (54.5%) . More than one quarter of the women(25.9%) never used condoms, 49.4% sometimes used condoms and 24.7% used condoms every time. Twenty-eight women (31.8%) had an induced abortion because of an unexpected pregnancy. Fourteen (14.9%) had been infected with STDs, and four IFFWs(2.8%)had tried drugs before the interview. Conclusion: In order to empower the IFFWs in the city to protect themselves from HIV, and to contain the rapid spread of HIV in our province, targeted HIV/ AIDS health promotion programs should be urgently implemented among IFFWs in Dongguan city. The programs should be designed to improve the knowledge of HIV, to promote condom use, and to reduce risky behaviors.展开更多

Principles and theories of the renovation design were introduced, it was proposed that protection and landscape renovation of industrial heritage had to be insisted to make regular and unique overall spatial layouts. On this basis, design approaches for the wasteland landscape renovation of the steel-casting factory were proposed as "maintaining original images, realizing the functional substitution; optimizing spatial structure; updating seriously-damaged industrial facilities with insignificant functionality; improving and recovering landscape soil; recovering and reconstructing vegetation".展开更多
