Breast cancer is increasing at a remarkable rate in Korea. We investigated the association between oral contraceptive use and breast cancer in Korean women. Using the 5th Korea National Health and Nutrition Examination Survey data, 8,495 women aged over 30 years are analyzed. Furthermore, the data used in this study is obtained using a complex sampling method in order that it is generalized. The previous studies in Korea, were not statistically significant due to the relatively short duration during which oral contraceptives had been available. However, the longer duration of oral contraceptive use exhibits tendency to increase the risk of breast cancer. Women using oral contraceptives, particularly for more than two years have an increased occurrence of breast cancer compared with women who do not use oral contraceptives. This result reflects the late introduction of oral contraceptives in Korea compared with developed countries. The recent increase in interest about the use of oral contraceptives has been increasing for a variety of reasons. Therefore, it is necessary for continuous and specific clinical studies to examine the connections between the first use of oral contraceptives, oral contraceptives use duration, adverse effects of oral contraceptives and breast cancer in order to develop strategies for preventing breast cancer.

This study was done to examine knowledge and attitude towards sex and the needs for sex education of korea female students in college. Data for this study was collected through questionnaires filled-out by 464 female students from September 2002 to December 2002. The result of this study were as follows； The subjects' scores of sex knowledge was 19.60 on average devided into the lovest 1 to the highest 25. Reproductive physiology scored highest at 0.82 and the contraceptive method was the lowest at 0.54. The subjects showed a positive sex attitude as 48％ were for the abortions before marriage, a they appeared the most negative as 4.3％ were for extramarital coitus of women. The subjects who responded that sexual education is necessary were 423 (91.2％), and they wanted ‘the sexual mentality of men and women’ most, 419 (99.1％). Also, ‘contraceptive method’ of 404 (95.5％), ‘veneral disease.’, ‘sexual behavior’, ‘sexual physiology’, ‘reproductive physiology’, ‘sexual morals’ etc followed. Based on above results of the study, it is more essential to organize the sex education programs centering around ‘contraceptive method’, ‘veneral disease.’, ‘sexual behavior’ etc which are not too difficult but more needed than ‘reproductive physiology’. It is required to develope sex education programs through research between specialists in various fields rather than through specialists in one field. It is considered that sex education programs can lead female students to forming and maintaining a correct sexual identity.

The purpose of this study was to investigate the sexual knowledge and the needs of sex education for college students in order to develop sex education program. The data were collected from 271 students attedning K community college in Chungcheongbuk-do from November, 29 to December 3, 1999, using a self-administered questionnaire. Sexual knowledge in this study include 4 areas such as sexual physiology, contraceptive methods, venereal disease. and reproductive physiology. The results were as follows : 1. The mean score of the knowledge in sex was 15.42 out of 29, which is very low. Of the four areas of the knowledge, the students showed the lowest score in contraceptive methods. Woman students had significantly higher score in reproductive physiology than man students. 2. Seventy nine percent of the students felt the need for sex education being given by their college. Most students wanted to obtain sex education through special lectures $(55.7\%)$ or regular curriculum$(29.2\%)$, Those specialists in sex education were most prefered. with regard to the contents of sex education, sexual psychology was most frequently indicated followed by contraceptive methods, pregnancy, satisfy ways of sexual drive. About forty two percent of the students thought preschool age as the adequate stage for beginning sex education. 3. Sexual knowledge was statistically significant in terms of grade. major. and dwelling state.

Korean family planning program has been adopted as a part of the Economic Development Plan with strong national government backup. After initiation of family planning program, the increase rate of total population declined from 2.6 percent during 1955-1960, to 2.1 percent in 1960-1975, and 1.6 percent in 1979. Of course, we do not ascribe this population increase rate decline to the national family planning program alone. Other contributing factors have been changes such as growing numbers of induced absortions, a rising marriage age and economic development. Currently, 2,600 family planning workers are assigned in all myun of the country. 21 percent of the works are registered nurse, 9 percent are midwife and aid nurses occupy 70 percent (Table 1). Authorized clinics are 2,329 which composed 1,765 IUD clinics, 1,070 vasectomy clinics and 1,150 Fimale sterilization clinics (Table 2). Cumulative contraceptive services provided by government program, 1962-1974 is illustrated in Table 3. After government program in family planning has been initiated (1962-1978), estimated number of births averted by each methods was measured (Table 4). From 1962 to 1978, tendency of contraceptive acceptors is illustrated in Table 5 showed that IUD, oral pill and condom program is decreasing and in other hand, sterilization program is increasing very much. Attitude change toward family size (1965-1978), contraceptive practice and son preference are showed in Table 7, 8, respectively. Auther concluded that future program in family planning should target to the point, that smaller family size norm for maternal health should be emphasized rather than smaller size family for national development.

A good animal model that simulates the human subject has not been available for the evaluation of the in vivo effectiveness of vaginal contraceptives. After careful consideration, The stumptailed macaque (Macaca arctoides) was studied for its applicability since it has a reproductive tract similar to that of the woman, is easy to handle, does not require tranquilization or anesthesia when the contraceptive is deposited, and breeds and conceives readily under caged conditions. The reported observations show the usefulness of this animal. Both postcoital sperm motility studies and breeding experiments were performed with the use of Delfen vaginal cream and K-Y jelly. K-Y jelly had no effect on the motility of vaginal spermatozoa or on the conception rate of the primates. Although Delfen vaginal cream consistently immobilized all spermatozoa in the postcoital test, half of the animals became pregnant within an average of 3.7 breeding cycles. These results illustrate the discrepancy between spermicidal tests and fertility measurements, and it is recommended that primate-breeding experiments be performed before a spermicide is evaluated in women as a contraceptive.

The extraction of third molars is a common task carried out at dental/surgery clinics. Postoperative pain is one of the two most common complications of this surgery, along with dry socket. Knowledge of the frequent risk factors of this complication is useful in determining high-risk patients, planning treatment, and preparing the patients mentally. Since the risk factors for postoperative pain have never been summarized before while the risk factors for dry socket have been highly debated, this report summarizes the literature regarding the common predictors of postextraction pain. Except for surgical difficulty and the surgeon's experience, the influences of other risk factors (age, gender and oral contraceptive use) were rather inconclusive. The case of a female gender or oral contraceptive effect might mainly be associated with estrogen levels (when it comes to dry socket), which can differ considerably from case to case. Improvement in and unification of statistical and diagnostic methods seem necessary. In addition, each risk factor was actually a combination of various independent variables, which should instead be targeted in more comprehensive studies.
