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

This paper summarises the historical background, development and current situation of the old site of public high school in Lvshun by approaches such as historical literature research and present situation surveying. Then, it analyses the characteristics of public high schools in Lvshun in four aspects: architectural scale, plane function, architectural style and material structure. After that, the school is judged to have four dimensions of value: historical, technological, and cultural and use value. In the end, this paper explores the protection and reuse of the building from the aspects of authenticity, suitability and integrity. It is intended to provide a theoretical basis for the protection and reutilization of modern architectural heritage.展开更多

A stratified two--stage cluster sampling plan was designed for thesurvey. The paper presents the methods of stratification, selecting n=2 PSU's (cities/counties) withunequal probabilities without replacement in each stratum and selecting residents/village committeein each sampled city/county. All formulae of estimating population characteristics (especiallypopulation totals and the ratios of two totals), and estimating variances of those estimators aregiven. Finally, we analyse the precision of the survey preliminarily from the result of dataprocessing.展开更多
