부산지역 대기질에 대한 대기 오염 지수(PSI)의 적용

문윤섭,장난심,김영주 부산대학교 환경문제연구소 1997 環境硏究報 Vol.15 No.1

The Pollutant Standards Index (PSI) was chosen as an environmental indicator. The PSI is a composite indicator computed from ambient levels of SO2 , TSP,O3 , NO2 , and CO. The daily PSI value is determined by the pollutant having the highest reading for that day. The index numbers are on a scale of zero to 500, the most important number on the scale is 100, which corresponds to the EPA - set National Ambient Air Quality Standars (NAAQS). Scores higher than 100 are considered to be unhealthful. Air quality of Pusan was evaluated by Pollutant Standards Index, which was proposed by Federal Register of the United States. The daily data of pollutants (SO2 , TSP, O3 , NO2 , CO) in 6 air pollutant monitoring sites were used for evaluation. According to the frequencies (day/day %), most parts were still under unhealthful condition. But, this result was why too many data of the high O3 concentration value in summer was missing. As the result, PSI method seems very useful to evaluate air quality, if the air quality pollutant data has no missing one, but it would be necessary to reform in consideration of environment standard of Pusan, in the case of applicating PSI in Pusan, Korea.

산전 태아사망 환자에서의 Mycoplasma hominis와 Viridans streptococcus감염 1예

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.

We calculated dose rate using equations to consider radiative processes distinctly. The does rate at Pohang(36˚02'N,129˚23'E) was calculated using measured ozone and meteorological data and two-stream approximations(quadrature, Eddington, delta eddington, PIFM(practical improved flux method), discrete ordinate, delta discrete ordinate) are used in solving equation. The purpose of this study is to determine the most compatible radiative transfer approximation for simulating the radiative and photochemical processes of atmosphere through comparision between calculated and measured values. Does rate of the biologically effective irradiance in the region 0.28-0.32um showed the highest value when quadrature Eddington was used and lower value on condition that delta scaling was applied. Correlation coefficient between dose rate at surface using radiation transfer equation and measured UV-B at Pohang was 0.78, 0.76 and 0.81 when delta Eddington, PIFM and delta discrete ordinate were used. Also, in case of above approximations were used, MBE(Mean bias Error) was within -0.3MED/30min and RMBE(Relative Mean Bias Error) was below 10% between 1200 LST and 1400 LST. Approximations which are compatible in estmating radiative process are Eddington, PIFM and delta discrete ordinate. Especially, in case that radiative process is considered more detail,delta discrete ordinate increased the number of stream is proper.

Current fire safety in the construction sites has developed piecemeal over a considerable period of time. However, the law and regulation of fire safety is insufficient to protect fire in the construction sites. The frequency of fire in the construction sites is very rare but it brings longterm deterioration durability of building structure and large scale industrial calamity. There are many process of works and each work deals with many kind of flammable material, so it is very difficult find a proper safety fire prevention. This study executed the questionnaire and fire experiment of the welding work to provide effective fire prevention counterplan.

Purpose: Because studies about the control of penile erection at the entral nervous system was dependent on the animal experiments, establishment of measuring penile erection is important to evaluate the effects changes at the central nervous system on the penile erection. Intracavernous pressure measurement in rats has been introduced as a suitable index for the evaluation of penile erection but this method is invasive and technically difficult. So, we established the intracavernous pressure measurement in rats as the experimental index for penile erection. Materials and Methods: 42 male adult Sprague-Dawley rats (250-300gm) were divided to saline or papaverine treated group. Rats were placed on a heating table to maintain their body temparature and anesthetized with 50mg/kg of pentobarbital sodium by intraperitoneal injection. A cannula was inserted to the left carotid artery to measure systemic blood pressure. Saline (0.05, 0.1ml), papaverine(0.05, 0.1, 0.25, 0.5, 1.0, 2.0mg) were injected intracavernously via 26 guage needle filled with saline or papaverine which connected to pressure transducer and polygraph was inserted into the corpus cavernosum on one side to inject the drug and to measure intracavernous presure. Results: Properly executed insertion and intracavernous administration produced a instantaneous but transient rise in intracavernous pressure that substantially stabilized and maintained at 5.4±0.4mmHg. Intracavernous pressure and duration of penile blood flow following intracavernous injection of papaverine are increased comared to those of saline. Conclusions: Monitoring intracavernous pressure in rats represents a suitable index for the evaluation of penile erection in small laboratory animals.

Purpose: Hippocampus contains interneurons where glycine is located, but the connectivity of these has not been well studied. Glycine may influence the serotonergic nervous system through the interneurons. Serotonergic nerve fibers pass through nearly all areas of the hippocampus. We investigate the effects of glycine on serotonin release from rat hippocampal slices for the better understanding of the complex effects of glycine at the hippocampus. Materials and Methods: The hippocampus was obtained from the male rat brain and sliced. The slices were incubated in a buffer containing 0.1mM [^(3)H]5-hydroxytryptamine(5-HT) for uptake. The release of 5-HT into the buffer during each 10 min period was measured and the radioactivities in each buffer and the tissue were counted using liquid scintillation counter and the results were expressed as a percentage of the total activity. After 50 min from the initiation, glycine were administered at 6th and 7th 10 min period respectively. The changes of 5-HT release were expressed as percent values compared to the 5th 10 min period. Results: A steady release of 5-HT was observed up to 100 min after the rapid release during the first 40 min. The 5-HT release during 10 and 20 min of glycine(10_(-6)M) treatment showed no significant change than those of control group. Conclusions: The release of 5-HT was not changed by glycine. This results suggest that glycine does not influence on the serotonergic nervous system that is responsible for the inhibition of the penile erection as well as induction of the penile erection.

Overactive bladder including frequency, nocturia, urgency ate common and Its cause is decreased bladder storage capacity. Non-pharmacologic therapy to facilitate bladder storage capacity are behavioral, bladder overdistention or electrical stimulation. For behavioral therapy, patient education about lower urinary tract function, information about lifestyle changes or dietary modification, bladder training which includes instituting intervals of timed voiding and gradually increasing these intervals, pelvic floor physiotherapy with or without biofeedback are necessary. For physically or mentally challenged individuals, schedulled toileting or prompted voiding is necessary, too. Bladder overdistention, electrical stimulation or neuromodulation are also used for the treatment of overactive bladder.
