The purpose of this study is to examine the prevalence and correlates of three types of risk-taking behavior among high school students in Korea in a cross-sectional national sample. A sample of 636 male and 622 female high school students is analyzed using descriptive statistics and logistic regression. Three types of risk-taking behavior are examined: drinking alcohol, smoking, and premarital sex. The results are as follows: Forty-three percent of students in the sample have ever drunk alcohol, 32% have ever smoked, 11% have experience premarital sex. Risk-taking behavior is more prevalent among boys than among girls. Boys and girls in Seoul are much more likely to have experienced three types of risk-taking behavior. Not having two parents in the family and having lived away from immediate family increase the likelihood of some risk-taking behavior. Students who have a friend with premarital sexual experience are much more likely to have experienced premarital sex themselves. Among sexually active students, having multiple sexual partners is common and prevalence of condom use is low. Reproductive health education at school has no effect on students' sexual behavior. The prevalence of risk-taking behavior among adolescent in Korea is likely to rise in the future. Substantial proportion of adolescents are exposed to the risks of STDs and substantial proportion of adolescent girls risk premarital pregnancy. Current health education programs are inadequate in protecting students from risk-taking behavior. Students whose families do not include both parents and students who live away from their immediate families need special programs to protect them from risk-taking behavior.

Purpose: This study investigated the influence of cervical cancer knowledge, human papillomavirus (HPV) knowledge, self-efficacy, and uncertainty on the intention to engage in cervical cancer preventive behavior in HPV-infected women. Methods: This descriptive correlational study was conducted among 129 adult women aged 20 to 65 years who received positive HPV results at a general hospital in Changwon, Korea. The dataset was analyzed using descriptive statistics, the independent t-test, analysis of variance, the Pearson correlation coefficient, and multiple regression. Results: The mean score for the intention to engage in cervical cancer preventive behavior was high (4.43±0.65). This intention was significantly different according to age at first sexual intercourse (F=7.38, p=.001), HPV type (F=4.79, p=.010), vaccination (t=3.19, p=.002), and condom use (t=3.03, p=.003). The intention to engage in cervical cancer preventive behavior showed significant, weak-to-moderate positive correlations with HPV knowledge (r=.22, p=.012) and self-efficacy (r=.42, p<.001). Self-efficacy (β=.46, p<.001), first sexual intercourse at <20 years (β=.45, p<.001), first sexual intercourse at 20-24 years (β=.29, p=. 018), HPV high- and low-risk group infection (β=.26, p=.019), HPV high-risk group infection (β=.26, p=.026), and vaccination (β=.21, p=.007) significantly influenced the intention to engage in cervical cancer preventive behavior. These variables explained 34.6% of variance in intention. Conclusion: Study findings support the need to develop a program that effectively conveys accurate information about cervical cancer prevention to HPV-infected women and helps them enhance self-efficacy to boost the intention to engage in cervical cancer preventive behavior.

Purpose: Any battery impacted in the esophagus must be removed urgently because of the possibility of serious complications such as perforation, fistula, and mediastinitis. The use of endoscopic procedures was compared to find the most rapid, effective, and safe method to remove disk batteries. Methods: The cases of 24 children (9 males, mean age, 1.5 years) that had accidentally ingested disk batteries were reviewed. The patients had visited the Department of Pediatrics, Kyungpook National University Hospital from July 1997 to June 2007 for the removal of disk batteries. Endoscopic removal was attempted using a retrieval net or a magnetic extractor with a balloon (condom). The procedure times for removing the ingested battery were compared. Results: Children that ingested batteries with a larger diameter (20 mm) had a greater chance to have esophageal impaction with serious injury, such as esophageal mucosal necrosis or ulcers, as compared to the ingestion of smaller diameter batteries (10 mm) (p<0.01). Endoscopic removal of disk batteries was attempted either using a retrieval net in 10 children or by using a magnetic extractor with a balloon in 6 children. Endoscopic removal using a retrieval net was more effective (mean procedure time: 1.5 min) as compared to using a magnetic extractor with a balloon (mean procedure time: 3.3 min) (p<0.05). Conclusion: Both procedures, either using a retrieval net or a magnetic extractor with a balloon were effective in removing ingested disk batteries. Based on our experience, an endoscopic procedure using a retrieval net was a more effective method for foreign body removal.

This study was conducted to investigate the survival rate of frozen-thawed spermatozoa in equine by glycerol concentration and freezing speed Two stallions (1 Thoroughbred-13 year old and 1 Arab-7 year old) bred in Korea Racing authority was examined for 1 times in a couple of weeks. Semen was collected by condom method standing heated mare and were centrifuged 650 g for 15 min. and isolated the seminal plasma. Thick fraction of semen was diluted EDTA-Lactose-egg yolk diluents to 1:1 and contained in 0.5 ml straw as $6{\sim}14{\times}10^7\;cells/ml$. Final concentrations of glycerol were 3, 5 and 7% in cryopreseved diluents and added 4 times for 2 hours equilibration. For the freezing, equilibrated straws were located 3 or 5 em above $LN_2$ gas for 5 or 10 min. Survival rates of pre-frozen sperm were $65.0{\pm}13.2%$, $68.3{\pm}10.4%$, $66.7{\pm}11.5%$ and post-frozen were $53.3{\pm}23.1%$, $45.0{\pm}15.0%$, $50.0{\pm}18.0%$ in 3, 5, 7% glycerol concentration, respectively. There was no difference between glycerol concentrations. Survival rates of frozen-thawed sperm on freezing speed were $36.7{\pm}10.4%$, $40.0{\pm}7.1%$, $30.0{\pm}13.2%$ at 3 cm-5 min and $33.3{\pm}11.5%$, $31.7{\pm}2.9%$, $21.7{\pm}10.4%$ at 3 cm-10 min in 3, 5, 7% glycerol concentration, respectively. Survival rates of frozen-thawed sperm on freezing speed were $43.3{\pm}15.3%$, $32.0{\pm}17.9%$, $22.3{\pm}15.7%$ at 5cm-5 min and were $47.5{\pm}15.0%$, $43.3{\pm}12.6%$, $48.3{\pm}15.3%$ at 5cm-10 min in 3, 5, 7% glycerol concentration, respectively. There were significantly different between groups (p<0.05). These results suggest that glycerol concentration did not affect cryopreservation of stallion semen within 3~7% but freezing speed affects. In our experiment, the best cryopreservation condition was at 5 cm above $LN_2$ gas for 10 min for pre-freezing and 7% of glycerol concentration. These results lead to commercial AI with frozen-thawed stallion semen.

Rapid socio-cultural and economic changes in the country has brought with it changes in the society's value system. For a traditional society that is increasingly being exposed to modernization but where sex norms are still very restrictive, the adolescent sexual mores takes on added significance. Adolescents are caught between two opposing forces, the changing environment that allows for freer and liberal mores and the traditional society that cannot keep pace with the changing environment and therefore demands resistance to changes. This paper focuses on problems of adolescent sexuality in this country and considers the countermeasures for the existing problems. Amongst the problems are: (a) increasingly younger age of the adolescents who start sexual intercourse (b) non-use of contraception, (c) unwanted pregnancies, (d) increase in the number of induced abortion and (e) increase in the number of unwanted children and unmarried mothers. The Korean adolescent's sexual behavior seems to follow that of the developed countries. In other words, many western modes of life and sexual values seem to bave been copied in Korea and yet Korean adolescents lack in their knowledge of sex related matters such as reproductive physiology and contraception. Among middle and high school students, female students are reported to have less knowledge on sex than male students according to a 1988 survey by KIPH. Even among the unmarried famale factory workers, only 42.5 percent replied they know of the condom, and 25.1 percent and 23.1 percent said they had knowledge of spermicide and menstrual regulation respectively. However, 14.9 percent and 13.9 percent reported that they had a knowledge of the loop and female sterilization respectively according to the 1984 study by KIPH. Among the middle school students 0.8 percent said they had experience in sexual intercourse, while 7.3 percent of the high school students reported having had sexual intercourse. The sexual intercourse experience rate among the unmarried female factory workers is 37.8 percent. Among those female factory workers with sexual experience, 46.7 percent had more than one sex partners. Only 39.1 percent of male students and 18.9 percent of female students among those with sexual intercourse experience have used contraceptives. mostly condoms and oral pills 45.1 percent of female factory workers with sexual intercourse experience used contraceptives such as pills, condoms and rhythm methods. The pregnancy experience rate among the female factory workers who had experience in sexual intercourse is 29.5 percent, which is 11.1 percent among the total respondents. Out of the 102 pregnant female workers, 98 workers(96.1 percent) terminated their pregnancy by induced abortion and 2 workders(2 percent) in natural abortion, while 1 worker(1 percent) was in pregnancy and another 1 worker had normal birth that was subsequently sent to orphanage. In order to cope with the problem of adolescent sexuality, a drastic and strong policy measures should be taken by the government. The most effective countermeasure to the adolescent sexual problems appears to the education. The sex and population education in the school is very much in need. In addition, sex education program through mass media and at the job sit-should be promoted for a healthy development of adolescents' sexual behavior. Also, the existing national family planning program, which has focused on the married couples, should be extended to the unmarried people in its scope and contents of the program.

In order to determine the knowledge of, attitudes to, and practice of housewives toward health care in a rural area, a survey with questionnaire was carried out with 87 housewives who were sampled randomly from 6 villages in Sudong Myun, from April 16th to 21st, 1979. The following results were obtained. 1. Of the housewives studied, 61.5% knew that B.C.G. is a vaccine for T.B prevention and 12.3% knew that D.P.T. is a vaccine for diphtheria, pertussis, and tetanus. 2. The vaccination rate of the children under six-year of the housewives studied was: polio 83.1%, B.C.G. 75.4%, D.P.T. 66.2%, and measles 55.4% respectively. 3. The vaccination rate was higher in children in the area near from the health subcenter than in there of the area further away. 4. Out of 87 respondants, 87.5% knew one or more methods of contraception for spacing children. These were: loop 69.0%, oral pill 66.7% and condom 14.9% respectively. 5. Out of 87 respondants, 82.2% knew the methods of contraception for sterilization. These were: laparascopy 87.5% and vasectomy 16.9%. 6. Out of 87 respondants those who had experience using contraceptive methods were 70.1% and present users were 47.1%. 7. Contraception practice rate was higher in the group of housewives having middle school education or above than those having primary school education or less. 8. Functions of the health subcenter listed by respondants were: patients care 72.4%, family planning 31.0%, vaccination 23.0%, T.B. control 3.4%, health education 3.4%, infant birth delivery assistance 1.1% respectively. 9. Housewives who knew that there is a village health voluntary worker in their own village were 63.2%(55), and 58.2% of those who knew appreciated her activities. 10. Purposes of expenditure of Myun community health development funds listed by respondants were: aid for patient care 34.5%, aid for health subcenter operation 16.1%, and aid for Myun health development 6.9% respectively. 11. It seems that both of the distance from the health subcenter and the utility rate level of the village health voluntary worker are co-related to the B.C.G. vaccination rate of children. 12. It seems that both of the distance from the health subcenter and the utility rate level of the village health voluntary worker are not co-related to the rate of contraception practice.

1. Introduction Community medicine with the concept of comprehensive medical care and an ideal medical care delivery system not only for an individual or family but for the whole community has emerged. In April 1970, the Presbyterian Medical Center started a hospital based community health service project in order to improve the health of the people in rural areas. Prior to commencing a comprehensive medical care system, a family survey was needed. The major objective of this survey was to obtain information concerning the people and their environment so as to be able to plan and implement a comprehensive medical care program in Soyang-Myun. 2. Survey Method An interview using a family record form was carried out for each household. This family record form was designed to get information about demography, family planning, environmental sanitation and vital statistics. Prior to beginning, the members of the survey team were trained in interviewing techniques for three days. The team consisted of a public health nurse, four nurse-aides, a sanitarian and four health extension workers who are working in our project, The survey was carried out during the period November 1971 to March 1972. 3.

In recent years, explosive increase in population has been damaging mankind in terms of deprivation of natural resources and more of economical demands. Therefore, we have thought about problems as to counter-balance the increasing population, and reached a resolution of artificial methods of controlling birth. In the past, though now used in some of contraceptive methods, extravaginal ejaculation, condom were commonly used. But recently, pills, IUD and several kinds of operative procedures are quite popular. Though the recent methods are known to be effective compared with the traditional methods, a certain unwanted side effects as well as limited value of usages now must be discussed. On this aspect, we are trying to research for a ideal methods such as symptom free, more of natural way of family planning and try to zero the failure rate. And also it has been suggested that only if those scientific methods of controlling birth can be base on religious concepts of moral being, it will be enlightened. At the Happy Family Planning Clinic of St. Mary's Hospital, we apply Billing's ovulation method to out-patients who want contraception and usually advise them to use it on a self-care basis. For a retrospective study of the presurvey data analysis and use-effectiveness of the ovulation method from April 1, 1975 to Nov., 30, 1975, we have dealt with a total of 1,383 women (urban areas 465, rural areas 918). The results of preliminary survey were as follows; 1) Among 465 women in Seoul areas, the failure rate was 10.3, which signified unplanned pregnancies of 32 women. 27 of the 32 women were pregnant due to the users own failure and the remaing 5 due to the failure of the method. Therefore, the failure of the method accounted for 1.6. 2) Among 918 women in rural areas, the failure rate was 15.2 signifing unplanned pregnancies in 93 women. The cause of the failure in 81 of the 93 women was attributable to the user's own mistake and that in the remaing 12 to the default of the method. Therefore, the failure attributable to the method accounted for 2.0.

To measure the fertility rate and pregnancy wastage of women in rural area, 3,780 married women under 50 years old who were not sterilized either woman or husband in Gunwee county were followed up for 2 years. Seventeen Myun health workers visited these women periodically to check the status of their family planning practice and menstruation. Pregnant women were interviwed for their past obstetric history and followed up to the time of delivery. Family planning was practiced in 51.6% of the 6,826 women-years observed during the period from April 1, 1985 to March 31, 1987. Pregnancy, abortion and delivery covered 7.6% of the observed women-years and family planning was not practiced in 36.5% of the women-years. When sterilized women at the beginning of the study were included, the family planning practice rate was 72.1% which was slightly higher than the national family planning practice rate. However, 28% of the women of 30-39 years old had not practiced family planning although they had 2-3 children and they used more such less effective methods as safe-period method and condom than the women of 20-29 years old. Overall pregnancy rate was 14.3 per 100 woman-years. Women of 25-29 years old had the highest pregnancy rate of 27.4 per ,100 woman-years. Pregnancy wastage including spontaneous and induced abortions and still births was 22.0% of all pregnancies and it increased with the age of women; 15.8% in women less than 30 years old and 43.7% in women of 30 years and over. Women who terminated the pregnancy with induced abortion had more pregnancies, more previous induced and spontaneous abortions and shorter pregnancy interval than those women who terminated with live birth. Pregnant women terminated with a live birth had received 4.2 prenatal cares on the average. Eighty-five percent of deliveries occurred at a medical facility and 15% at home which was substantially lower home delivery rate than the other rural area of Korea. This may be due to the effects of the demonstration project for the primary health care in 1970s in Gunwee county. These findings suggest that family planning service in rural area should be strengthened by promoting the use of more effective contraceptive method among women over 30 years of age.
