The return rate of valid questionnaires was 96.6 %. The questionnaire investigation was conducted on a multiple-choice and anonymous basis. Data were input into computer and SPSS12.0 software package was employed for statistical analysis. Among the female students, 1196 had the experiences of hugging and kissing （50.57 %） and 423 （17.89 %） had sexual experiences （sexual intercourse）. The first sexual intercourse took place at the age of 19.23±1.74 y. There were significant differences in the sexual experiences among the majors of different subjects, with the rate of sexual experiences in art majors （43.17 %） and high-grade students （34.31%） being the highest. The causes of the first sexual intercourse included sexual impulse, curiosity, intention to strengthen the relationship or to show loyalty to boyfriend and sometimes violence. While the motives of the sexual intercourse within the past one year before the investigation were to satisfy the sexual needs and to strengthen the relation with their boyfriends. With both first intercourse and sexual experiences within last one year, the partners of the sexual intercourse were mainly their boyfriends （95.7 % and 97.3 % respectively）, but the partners also included acquaintances, ＂one night stand＂ partners and customers of sex trade. Some of them had multiple sexual partners, with the highest number of the sexual partners being 11. In the first sexual intercourse of the subjects, 44.0 % of them did not take any contraceptive measures; only 16.4 % of them used condoms. In the sexual intercourse within the last one year, only 44.6 % took contraceptive measures every time they had sexual intercourse. Among those who took contraceptive measures, 64.4 % used condoms. Among those who had sexual intercourse, 101 persons got pregnant, with a rate of pregnancy being 4.3 %, accounting for 23.9 % of all who had sexual intercourse. Among those who got pregnant, 78 persons got pregnant once; the others became pregnant more than two times, the highest being 5 times. There were 122 persons who had inflammation of reproductive system, mostly vaginitis. Other conditions included venereal warts and herpes genitalis. It is concluded that the rate of sexual behaviors is high in female college students and there exist promiscuity, unexpected pregnancy and transmission of STD in the students.展开更多

Bluetongue virus （BTV） belonged to Reoviridae is ARN genome of 19 Kb. Twenty-six BTV serotypes have long been recognized, to be associated with severe disease in certain breeds of sheep, whereas cattle and goats are usually sub-clinically affected. Before 2004, BT was considered an exotic disease in Morocco, however, the first outbreak was observed in 2004 in sheep. This outbreak was caused by the isolated BTV-4. Two years later a BTV-1 emerged in Morocco. Both serotype 1 and serotype 4 circulated after 2007 across the country. The aims of the present work was to perform a serological study on sheep from different regions in Morocco in order to clarify the current BTV epidemiological situation and its evolution from 2009 to 2012, to determine the co-infection rate, and to confirm the possible circulation of other BTV Serotype mainly the BTV-8. All of 436 sera were tested by serum neutralization using reference strains. Results confirm the presence of BTV-4, BTV-1 and BTV-8. However, the present study report for the first time the emerging BTV-8 circulation in Morocco. Moreover, the founding reveal as well a higher co-infection rate in cattle compared to sheep.展开更多

An analysis of domestic research is important for better understanding of web surveys, to guide further research and application. This paper gives a bibliometric analysis of 120 domestic articles on web surveys from 1998 to 2006, on publication growth, author and organization distribution, journal distribution, and research subjects. Research on web surveys in China should make progress comparable with research abroad in comparative studies, specific studies, and technical application studies.展开更多
