Intending to offer basic information for a prospective health services in Korea, this study is to investigate the complication caused by sterilization in goverment family planning program from 1962 to 1995. The results are as follows: 1. Total number of sterilization performed during the period from 1962 to 1995 were 1.367,772 cases of male sterilization and 2,889,635 cases of female sterilization. 2. Incidence of the complication caused by sterilization operation from 1980 to 1995 were 1,883(0.20%) out of 925,801 cases in vasectomies and 15,866(0.70%) out of 2,256,020 cases in tubal sterilizations. 3. Major complications in vasectomy were epididymities of 658 cases (34.9%), vas recanalization of 326 cases(17.3%), hematoma of 266 cases(14.1%), scrotal abscess of 184 cases(9.8%), sperm granuloma of 76 cases(4.0%),and other of 373 cases(19.8%). On the other hand, in tubal sterilization, ectopic pregnancy was the most significant complication of 15,078 cases (95.0%) among 15,866 total complications, followed by pelvic inflammatory diseases of 155 cases(0.9%), peritonities of 96 cases(0.6%), ovarian & tubal bleeding of 31 cases(0.2%), intestinal perforation of 16 cases (0.1%), uterine bleeding of 14 cases(0.1%), uterine cervix laceration of 1 case (0.1%), and other of 271 cases(1.7%), while 161 pregnancies(0.1%) were terminated and 43 cases(0.3%) with normal delivery. 4. The occurrence rate of the complication for each period showed that most of the complication cases by vasectomy occurred in a year after the operation -the cases were 1,256 (66.7%). 254 cases(13.5%) occurred between the next year and the 2nd year, 138 cases (7.3%) between the 2nd year and the 3rd year, 73 cases(3.9%) between the 3rd year and the 4th year, 52 cases(2.8%) between the 4th year and the 5th year, 31 cases(1.6%) between the 5th year and the 6th year, 79 cases(4.2%) over the 6th year. Tubal sterilization indicated that the occurred complication cases in a year were 2,175 cases(13.7%), 2,113 cases(13.3%) occurred between the next year and the 2nd year, 2,082 cases(13.1%) between the 2nd year and the 3rd year, 2,049 cases (12. 9%) between the 3rd year and the 4th year, 1,819 cases(11.5%) between the 4th year and the 5th year, 621 cases(10.2%) between the 5th year and the 6th year, 4,007 cases(25.3%) over the 6th year. 5. For the cost of complication treatment, total \7,928,229,000 were paid as medical expenditure in which \609,438,000 for vasectomy and \7,318,791,000 for tubal sterilization. Accordingly per capita expenses were \345,000 for vasectomy and \467,000 for tubal sterilization. As the proportion of government sterilization program was decreased after 1988, that of private sterilization program would be increased. So it is recommended to set a guideline for the private sterilization program and to continue government sterilization program for the lower class.

In this study, we estimate air pollutants emission from agricultural waste burning. We investigated activities related to agricultural waste burning such as crop burning rates, location, and time by region. The average crop burning rates per square meter farmland of fruits, pulses, barleys, cereals, vegetables, and special crops were $273.1g/m^2$, $105.7g/m^2$, $7.4g/m^2$, $121.0g/m^2$, $290.7g/m^2$, and $392.9g/m^2$, respectively. We estimated air pollutants emissions with pre-developed emission factors. The estimated air pollutant emission of agricultural biomass burning were CO 148,028 ton/year, $NO_x$ 5,220 ton/year, $SO_x$ 11 ton/year, VOC 59,767 ton/year, TSP 21,548 ton/year, $PM_{10}$ 8,909 ton/year, $PM_{2.5}$ 7,405 ton/year, and $NH_3$ 5 ton/year. When these results compared with the entire emissions of national inventory (CAPSS), CO, VOC, $PM_{10}$ account for about 17.8%, 6.2%, 6.7% of the total, respectively.

One hundred and fourty-one Bjork-Shiley Monostrut valves were implanted in 105 consecutive patients from November 1983 to February 1990. There were 61 male and 44 female patients with a mean age of 33.6 years at the surgery. The cummurative follow-up was 370.3 patient-years with a mean of 44.0 months per patient. The operative mortality rate was 3.8%, and the linealized late mortality was 1.18%/patient-year. The incidence of major complications were 4.59%/patient-year, and the actuarial rate of freedom from valve-related morbidity was 80.2$\pm$4.4% at 7 years. The 7-year survival rate was 90.5$\pm$4.1%, and the actuarial rate of freedom from thromboembolism at 7 years was 93.3$\pm$2.3%. The linealized annual rates of complication were ; structural valve failure 0.27% /patient-year, non-structural valve failure 0.54% /patient-year, thromboembolism 1.62% /patient-year; bleeding 1.62% /patient-year; endocarditis 0.54% /patient-year. On the basis of our experience, we judged the Bjork-Shiley Monostrut valve reliable, with similar incidence of valve-related morbidity of other mechanical prosthetic valves.

Purpose : This study was intended to measure seropositivities and the levels of mumps- and rubella-specific IgG of MMR vaccinees over 17 months of age in Korea. Materials and Methods : From June 1994 to April 1995 we obtained sera from visitors of well baby clinic and patients in Korea University Hospital, who were MMR vaccinees over 17 months of age and had no evidence of immunodeficiency. These 275 study population include 145 males and 130 females. Mumps- and rubella-specific IgG antibody levels were measured by ELISA. Cut-off values for seropositivity were 20 GU(Gamma Unit) in mumps and 0.17 in rubella. Results : 1) As age increased, seropositivities of mumps-specific IgG increased significantly, being 69.0% in 1.5~2 year, 75.0% in 3~4 year, 76.0% in 5~6 year, 90.0% in 7 year, 100% in 8 year, 96.9% in 9 year, 97.4% in 10 year, 97.4% in 11 year, and 96.6% in 12 year of age(p<0.001). 2) As age increased, the levels of mumps-specific IgG antibody(mean${\pm}$standard deviation, GU) increased significantly, being $64.9{\pm}66.5$ in 1.5-2 year, $117.7{\pm}126.4$ in 3~4 year, $152.3{\pm}147.1$ in 5~6 year, $194.3{\pm}168.2$ in 7 year, $258.1{\pm}190.6$ in 8 year, $193.1{\pm}130.1$ in 9 year, $225.7{\pm}119.6$ in 10 year, $220.7{\pm}114.3$ in 11 year, and $222.3{\pm}127.1$ in 12 year of age(p<0.001). There was positive correlation between age and mumps-specific antibody level (r=0.3282, p<0.001). 3) As age increased, seropositivities of rubella-specific IgG decreased significantly, being 72.4% in 1.5~2 year, 75% in 3~4 year, 72% in 5~6 year, 60% in 7 year, 44.4% in 8 year, 40.6% in 9 year, 28.2% in 10 year, 23.1% in 11 year, and 17.2% in 12 year of age(p<0.001). 4) As age increased, rubella-specific IgG decreased significantly, being $0.462{\pm}0.356$ in 1.5~2year, $0.438{\pm}0.306$ in 3~4 year, $0.287{\pm}0.179$ in 5~6 year, $0.204{\pm}0.139$ in 7 year, $0.189{\pm}0.153$ in 8 year, $0.124{\pm}0.121$ in 9 year, $0.093{\pm}0.114$ in 10 year, $0.104{\pm}0.135$ in 11 year, and $0.080{\pm}0.001$ in 12 year of age(p<0.001). There was negative correlation between age and rubella-specific IgG titer (r=-0.551, p<0.001). Conclusions : Eventhough seropositivities and the level of mumps-specific IgG increased as age increased, they are not enough to prevent mumps infection in 1.5 to 6 years of age. Seropositivities and the level of rubella-specific IgG decreased as age increased. Appropriate change in vaccine schedule may be needed to decrease the risks of mumps and rubella infection.

This study investigated differences in children's facial, behavioral, and verbal expressions of pride and shame by their age, and type and level of task difficulty when they succeeded or failed on tasks. The subjects were 55 4-year-old children from 2 day-care centers and 37 7-year-old children from 1 elementary school. Each child participated in pride and shame assessment sessions. Data were analyzed by means, standard deviations, repeated measures ANOVA, and paired t-test. When they succeeded on tasks, 4-year-olds showed more pride in behavioral expression than 7-year-olds. More pride in facial, behavioral, and verbal expressions were shown when subjects succeeded on difficulty than on easy tasks. Interaction effect for behavioral expression of pride was found between age and type of task difficulty. In verbal expression of pride, interaction effect was found between age, and type and level of task difficulty. When they failed on tasks, 7-year-olds showed more shame in behavioral and verbal expressions than 4-year-olds. More shame in facial, behavioral, and verbal expressions were shown when subjects failed on easy than on difficulty tasks. Interaction effect for facial expression of shame was found between age, and type and level of task difficulty.
