Emissions of air pollutants (TSP, SO2, NO2, CO, and HC) was estimated in Changwon city that has the industrial complex and basin terrain. We found that the emissions of TSP, SO2, NO2, CO, and HC were 897 tons, 3,287 tons, 5,706 tons, 10,057 tons, and 1,470 tons for a year, respectively and the main source of air pollutants were vehicle. The ratios of vehicle emissions to total emissions ware TSP 63.8%, SO2 26.1%, NO2 65.5%, CO 91.0%, HC 94.4%. The ratios of industry emissions to total emissions were TSP 30.8%, SO2 60.2%, NO2 25.2%, CO 6.4%, HC 3.7%. The ratio of life emissions to total emissions are TSP 5.4%, SO2 13.7%, NO2 9.3%, CO 2.6%, HC 1.9%. The concentration distributions of air pollutants simulated by ISCST3 model were similar to its emission distributions, and relatively high concentrations of air pollutants occurred in the Palyong-dong (industrial area) and Banlim and Chungang (residual area).

Shock wave lithotripsy monotherapy was performed in 180 patients with urinary calculi using Genestone 190 lithotriptor between January 1996 and April 1998. Age range of the patients was 17 to 71 years (mean of 44.7 years)and male to female ratio was 2.3:1. There were 54 cases(30%) with renal calculi and 126 cases (70%) with ureteral calculi. NO regional or general anesthesia was required, but parenteral analgesics were required in some patients. The spark voltage was from 16 to 22Kv and average numbers were 2.04 sessions and the mean number of shock per session was 2230±350. The success rates of urinary calculi below 5㎜, 6-10㎜, 11-15㎜, 16-20㎜ and over 21㎜ were 95%, 94%, 91%,75% and 50%, respectively. The success rates of renal, midureter and lower ureter calculi were 85%, 98% and 73%, respectively. There were no significant complications. We think that SWL monotherapy using Genestone 190 lithotriptor is effective and safe procedure for calculi of kidney and upper ureter and calculi below 15㎜.

Pusan is the largest coastal city with a population of about four million in Korea. Because of increased and confused traffic, photochemical air pollution become a major urban environmental problem recently. The photo-chemical air pollution weather forecasting method preciser than existing air pollution forecast method has been developed to forecast ozone episode days with meteorological conditions using the data measured at 7 air quality continuous monitoring stations from June to September using 2 years (1994, 1995). The method developed in present study showed higher percentage correct and skill score than existing air pollution forecasting in KMA (Korea Meteorological Administration).

Breakdown of the blood-testis barrier by infection, trauma, or operation allows sensitization of spermatozoal antigens. Sperm antibodies may be a relative cause of infertility in infertile males. Multiple assay techniques have been developed to detect antisperm antibody. Older tests have been supplanted by the newer immunoglobulin specific assays. Immunobead test was used widely. Interleukin(IL)-6 is necessary for formation of antibody. So, this study was performed to investigate the value of interleukin-6 in the detection of immunologic cause of infertility. The antisperm antibody titers and interleukin-6 was measured in 10 healthy males and 30 patients with chronic prostatitis using immunobead methods and enzyme immunoassay kit. Titers of direct and indirect IgG, IgA and IgM antisperm antibody(% binding) was 0/0.7±0.7, 0/0, 0/0.1±0.1 and 0/1.1±0.5, 0/0.1±0.06, 0/1.1±0.6 in control group and patients with chronic prostatitis. Titers of direct and indirect IgG, IgA and IgM antisperm antibody was 1.8±1.7,0, 0.3±0.3 and 0.3±0.9, 0, 2.8±1.1 in patients with chronic prostatitis whom the antisperm antibody was found in. There was significant difference in indirect IgG and IgM between control group and patients with chronic prostatitis whom the antisperm antibody was found in. The value of seminal IL-6(pg/ml) was 3.2±0.9 and 9.6±2.3 in control group and patients with chronic prostatitis. There was significant difference. The value of seminal IL-6 was 7.0±2.7 and 13.4±5.1 in patients without chronic prostatitis and patients with chronic prostatitis. There was no significant difference. It is suggested that the examination of seminal IL-6 alone can be useful to evaluate the immunologic state of seminal tract but can not take the place of Immunobead test that detect the antisperm antibody formation.

In this study, thermal diffusion caused by using air cooled condenser at LNG power plant in Yulchon was simulated through in numerical method (Matsuno scheme). The input data of model was used to seasonal wind components (u, v) of automatic weather system (AWS) and seasonal temperature ranges between inflow and outflow of opening air. The aim of this study was twofold : (1) to investigate sensibility analysis of thermal diffusion coefficient : (2) to simulate diffusion of heat source through the calculated effect height for season and stability variations. These sensibility analyses were performed in detail using two case studies one is to apply horizontal and vertical thermal diffusion coefficient as 50 m-ls-1 and 10 m-ls-1, the other is 30 m-ls-1 and 10 m-ls-1 respectively. It is well known that the sensibility for thermal diffusion coefficient is low owning to very similar results. Consequently, thermal diffusion for the first case is simulated by using effect height for season and stability variation. The temperature is under 1℃ at surface whereas that is high at near the center of effect height.

To investigate a horizontal windrose and the mixing height in Masan coastal area, a local atmospheric flow and the concentration of air pollutants were analyzed by abserved data from AWS, airsonde and air sampler. The land-sea breeze model and the ISCST2 model of U. S. EPA(Environmental Protection Agency) were used to predict the concentration of air pollutants such as SO2 and TSP. As a result, during spring the principal wind direction in the Masan region is mainly represented by windrose of the WNW and NW, which can be induced by land breeze and the SE and SSW of sea breeze even if weak wind speed. The mixing height during the measurement was marked with the range from 400 m(0900 LST) to 1450 m(1500 LST), and the height of an inverse layer was presented as the range from 30 m(2100 LST) to 150 m(0300 LST). It is very important to cosider the local wind field for the accurate diffusion and movement of air pollutants in coastal urban area. The atmospheric flow was simulated by the two-dimensional local wind model upon considering the orographic characteristics such as land-sea contrast, mountain valley and urban building. The result of air quality simulated by ISCST2 support that the dispersion pattern of the pollutants in that area was followed as local circulation system in coastal urban area.

After analyzing the correlation between air pollution and visibility, TSP and NO_2 is responsible for poor visibility in Pusan. After analyzing the correlation between meteorological factors and visibility, general pattern of humidity has clear negative correlation. The variation of wind speed has a positive correlation. In order to investigate the cause of poor visibility in Pusan area, the Andersen sampler and PM-2.5 are used to collect and analyze aerosol. This study was carried out to monitor the visibility using Forward scattering meter and to find out the characteristics and the cause of good visibility case and poor visibility case by measuring and analyzing a variety of parameters, such as particle size distributions, chemical compositions, and meteorological conditions in Pusan. According to the analysis of intensive sampling, NO_3^-, NH_4^+ ion concentration increased together with the mass concentration around 0.5∼2.5㎛ approximately during the case of poor visibility. NH_4NO_3, NH_4Cl, and NaCl were thought to be the major components of fine particles.

Mycoplasma hominis was isolated from a Bartholin's gland abscess 70 years ago, and ureaplasmas were isolated from the genital tract about 20 years later. Subsequently, reports incriminating mycoplasmas in the known adverse outcomes of pregnancy have been reported. Without doubt these genital mycoplasmas are able to invoke an inflammatory response and take part in the cascade of events that culminate in preterm birth. Amniotic fluid infection results in considerable pregnancy wastage in the pregnancy. In these cases Gram-positive organisms, especially group B streptococcus and Streptococcus viridans were the most common pathogens isolated. In our case, the patient has fever and vaginal discharge at 14+4 weeks gestation and two days after intrauterine fetal death was seen. The vaginal culture and sensitivity shown Mycoplasma hominis and Vihdans streptococcus. We experienced a case of Mycoplasma hominis and Viridans streptococcus infection in a patient with intrautehne fetal death and report with a brief review of literatures.
