PURPOSE: The purpose of this study was to survey the health behaviors related to reproductive health, reproductive health history, and sexual behaviors of college students in local areas. METHOD: With a survey design, 792 college students from C and D areas were recruited to assess health behaviors such as smoking and alcohol drinking, as well as history of reproductive health and sexual behaviors. The data were collected by a self-administered questionnaire from November to December, 2007. RESULT: Mean age of the students was 20.8(SD=1.96) and gender distribution was 29.2% for male and 70.8% for female. Unhealthy behaviors were alcohol drinking, smoking, excessive weight loss, and irregular exercise; unsafe sex practices were experience of sexual intercourse with multiple sex partners and history of sexually transmitted disease (STD). Male students had more alcohol drinking (p=.04), smoking(p<.001), excessive weight loss(p=.01), experience of sexual intercourse with multiple sex partners(p<.001), history of STD(p=.025) compared to females. On the other hands, female students participated in regular exercise less than males(p<.001). CONCLUSION: College students seem to perform unhealthy behaviors related to reproductive health and less effective way of safe sex practices. Therefore, a planned education program for reproductive health promotion operated by college level is needed to assess and improve the level of reproductive health in college students.

PURPOSE: Increased technologic capabilities have allowed for the expanded use of ultrasound beyond simple differentiation of a lesion as solid versus cystic nature, allowing us to classify lesions into various categories based on a number of descriptive features. The purpose of this study was to investigate whether to predict the preoperative prognosis of breast cancer through the correlation between ultrasonographic images and the grade of malignancy. MATERIALS AND METHODS: The patient population for this study consisted of 107 patients with infiltrative ductal carcinoma who were evaluated using ultrasound technology. Ultrasonographic findings were divided as follows: Type I, round or oval shape and regular border; Type II, partially round or oval shape and partially irregular border; and Type III, irregular shape and irregular border. RESULTS: 1. The frequency of grade 1 (G1) was significantly higher in the Type I group than the othergroups. 2. In the 2.0 cm sized mass, the lymph node metastasis rate was significantly lower in the Type I group than the other groups. 3. In all the groups, Estrogen receptor (ER) positivity was insignificant regardless of tumor size and type. 4. In the 2.0 cm sized mass, c-erbB-2 positivity was significantly lower in the Type I than the other groups. There was no clear difference among the three groups in tumors greater than 2.0 cm in size. CONCLUSION: These results show that our classification of ultrasonographic images reflect the grade of malignancy in terms of clinicopathological features in breast cancers less than 2.0 cm in size. Therefore, ultrasonographic findings may help predict the preoperative prognosis in T1 size breast cancer, although further study is required.

BACKGROUND: To evaluate the usefulness and compliance of a hospital-based tabletop exercise in setting of pandemic influenza in hospitals. MATERIALS AND METHODS: Tabletop exercise was held in Pusan National University Hospital and forty two hospital employees were invited to participate in the exercise. The scenario for hospital-based tabletop exercise was designed. It consisted of three modules, which simulated the influx and outbreak of H5N1 influenza that was epidemic in Southeast Asia. Pre-, post-exercise surveys were completed by anonymous questions. RESULTS: Thirty-seven (88%) of 42 invited participants attended exercise. All members of the administration group and the ancillary services group participated. But, only 77% members of the clinical services group participated. In pre-exercise survey, priorities of eight goals regarding skills and knowledge during exercise were inquired., The highest priorities pointed out by the respondents were "Increase the knowledge of pandemic influenza" (22%), "Development of strategies for optimal communication among employees within specific department" (19%) and "Development of strategies for improved coordination between facilities within the health system" (19%). Twenty-one (57%) of participants completed the post-exercise surveys. At post-exercise surveys, 81% of the participants stated that the tabletop exercise was extremely or very useful, 86% of the participants also stated that it increased their knowledge of pandemic influenza. CONCLUSION: Tabletop exercise is an effective modality for increasing pandemic influenza preparedness in hospitals, and this method is useful for guiding preparedness activities within the hospital environment. Further studies to determine the appropriate method of discussion, questionnaire, duration of exercise and injection are needed.
