Airborne pollutants in the subway facilities can be potentially harmful to the health of passengers. This study was designed to examine whether the suspended particulates have mutagenic or carcinogenic effect on the plant cell systems. Total suspended particulates were collected with a high volume air sampler, in the entrance, the waiting room, and the platform of each subway station. The biological end-points in this experiment were the pink mutations in stamen hairs and micronuclei in the pollen mother cells of Tradescantia. The exudates were collected by shaking the filter papers from the sampler in distilled water for 24 hours. All the plant cuttings exposed to the exudates resulted in positive responses. The micronucleus assay proved more reliable and sensitive to the test than the stamen hair assay. The results indicate that the air particulates can give an adverse effect on the health of subway passengers.

The purpose of this paper was to analyze the current situation and problems of festivals through a case study of local festivals in the city of Seosan, Korea. It also examined ways to develop festivals. According to the analysis of festivals in Seosan, an economic ripple stemming from the festivals influenced the development of the city, through gradual improvement in various fields. However, some problems were found in event planning, execution and in satisfaction of festivals. To resolve these problems, suggestions to improve festivals were examined. This research compared and analyzed the performance of local festivals held in different areas up to present. In addition, through analyzing problems, this research suggests factors for festivals to create a higher cultural standard for Seosan citizens. The research also contributes to the culture of festivals in all of Korea.

The purpose of this study was to achieve fundamental data for design of air cleaner for general inhabitant space in Seoul area. The results of indoor air quality(IAQ) experiment was concentrated lower than indoor air quality criteria and ambient air quality criteria. Indoor air quality was analogous to outdoor air quality for ventilation of windows and etc. In spring, outdoor air quality had affected indoor air quality. But dust and carbon dioxide was concentrated higher than outdoor air duality and it appeared high concentration in time was caused by a lot of indoor activity by people. From this fact deduced that the result of amount caused by breath and indoor action was great. The effect of the indoor air quality upon the human body was higher than outdoor air quality.

The purpose of this study was to determine the optimum collection efficiency for various applied voltage of Electrostatic Precipitator. The experiment was performed between 15kV and 30kV. Collection efficiency was measured by Anderson Sampler(cascade impactor). The results of this experiment were as follows ; (1) In order to determine the ESP's optimum operating condition, we measured an electric property of discharging electrode. (2) Optimum applied voltage and overall collection efficiency were 25kV and 98.4%, respectively. (3) When applied voltage value was higher than 25kV, the collection efficiency shows a tendency to decline. We estimated that this result was due to ionic winds generated by electric field.

The 8th Asia Basketball Championships for Junior Woo Men was helf in Seoul, 1984. The following research and analysis of the game for 7 excenent teams (Korean, China, Japan, Philippines, Malaysia, Singapol Sri Ranka) was described. I intended to Study the items as follows; 1) Recovenie 2) Assist 3) Intercept 4) Block 5) Good Defensive 6) Error 7) Foul 1. Recoverie Other recoveries were 6.8 times in average. China team: 7.8 times in average. Malaysia team: 5.4 times in average. Malaysia team was worse than China team. 2. Assist Each assist was 11.8 time in average. China team: 21.7 times in average. Malaysia team: 4.2 times in average. Malaysia team was worse than China team. 3. Intercept Each intercept was 10.9 times in average. Korean team: 19.4 times in average. Malaysia: 8 times in average. Malaysia was worse than Korean team. 4. Block Each block was 3.8 times in average. China team: 7.3 times in average. Singapol team: 0.6 times in average, Singapol team was worse than China team. 5. Good defensive The total number of good defence was 3.6 times in average. Japan team: 5 times in average. Malasia team: 1.8 times in average, Malasia team was worse than Japan team. 6. Error The number of error per game was average 19.8 times and the team of Sir Lanka, which got the lowest points, was 33.5 times and the China team, winner was 11.5 times and I knew that the error in the basket ball game brought about an important effect in the game. 7. Foul The number of foul per one game was average 18.6 times in average China team 20.8 times and the team of Korea 17 times.

In this study, we evaluated genotoxicity of heavy metals among particulates with Tradescantia-micronucleus (Trad - MCN) assay in the various working environment. In a synthetic fiber factory and a rubber factory, chromium concentration was higher than any other heavy metals. On the other hand, nickel concentration was the highest in a semi-conductor factory. The difference in genotoxicity among the working environment was statistically significant as Trad-MCN frequencies were 4.67±0.35 MCN/100 tetrads (p<0.01) for the synthetic fiber factory, 5.73±0.81 MCN/100 tetrads (p<0.0I) for the rubber factory, and 15.60±2.58 (p< 0.01) (p< 0.001) for the semi-conductor factory. As a result, heavy metals among particulates in the working environment can be considered to have hazardous potential to human health, although they cannot directly induce DNA damage to the workers in the working environments.

Evans syndrome is defined as a simultaneous or sequential occurrence of autoimmune hemolytic anemia and autoimmune thrombocytopenia. Autoimmune hemolytic anemia (AIHA) is usually induced by IgG warm autoantibody or cold-active IgM antibodies reacting specifically with antigens associated with a patient's RBC. AIHA is a fairly uncommon disorder, with estimates of the incidence at 1 to 3 cases per 100,000 per year. Mixed-type AIHA is a relatively uncommon form of AIHA, with studies noting the incidence of 7-8% among cases of AIHA. We experienced a patient, 46-year-old woman who was diagnosed having a very rare clinical presentation of mixed warm and cold antibody mediated Evans syndrome. She was treated with corticosteroid therapy only and has been maintaining a complete response for 15 weeks. 저자들은 혼합형의 자가면역성 용혈성 빈혈과 자가면역성 혈소판 감소증이 동시에 발생한 혼합형 Evans 증후군으로 진단하고 스테로이드 요법 후 혈액학적으로 회복된 상태로 15주가 지난 현재 steroid 5 mg/일 까지 감량한 상태에서 추적 관찰 치료중인 46세 여자 환자를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.
