This study has been carried out to investigate the removal efficiencies of HCl/SOx in a Spray-Dryer/Fabric-Filter system. In HCl/SOx removal, we could identify the key factors such as spray dryer outlet temperature, molar equivalence ratio(MER) and fabric filter velocity, but we couldn't find out the correlation of HCl and SOx. The removals of HCl/SOx were inversely proportional to spray dryer outlet temperature(l30~170℃) and filter velocity(l.0~1.5 m/min), at the MER, HCl removal efficiency was strongly proportional to MER, but SOx, removal efficiency was not particularly increased by MER over 1.5. The removal efficiencies of HCl/SOx were improved over 10% at the fabric filter. In this Spray-Dryer/Fabric-Filter system, HCl/SOx removal efficiencies were about 99%, 96% respectively.

This study has been carried out to observe photodegradation efficieny of TCE with the variation of IN irradiation strength, liquid thickness and immobilized TiO₂. The results are summarized as fallows; 1. Without photocatalyst, the TCE removal efficiency was observed to be about 15% with UV irradiation. 2. Above 93% of TCE were mineralized by immobilized TiO₂on glass panel(5g, 500℃) and UV irradiation. The photodegradation efficiency increased with increasing UV lamp numbers and reaction rate increased with increasing TCE initial concentration. 3. The photodegradation efficiency decreased with increasing the liquid thickness and above 96% of TCE were removed with using 3 UV lamps and liquid thickness less than 6cm.

The purpose of this study is to investigate the error of using statistics in the articles of the Journal of the Korean Society of Anesthesiologists from 1981 ta 1990 and to present a program that may be of some help correcting the statistical error. We classified statistically the journals into original articIe, review and case report, and original articles into that of usng inferential statistics, descriptive statistics and no statistics. Then, we analyzed the articles of inferential statistics in the aspect of our criteria for statistical errors. The proportion of using erroneous inferential statistics was 80-100% from 1981 to 1986 and it decreased by 60% afterwards. But the proportion was still 67% in 1990. The representative errors are the no statistical analysis in spite of the necessary cases, the p-value only without the description of statistical method and using t test inappropriately in the comparison of more than 3 groups without Bonferroni correction. The other errors in using statistics were confusion between related data and independent data, inadequate numbers for Chi-square test, inapproate follow-up to variance analysis and inapproate parametric test for data in nominal or ordinal scales

Ik Soo Chung,Ho Sung Lee,Hong Ko,Byung Moon Ham,Seong Deok Kim,Kwang Woo Kim,Il Yong Kwak Korean Society of Critical Care Medicine 1987 Acute and Critical Care Vol.2 No.1
A clinical study was performed on the mortality cases among the patients who were admitted in the Respiratory Intensive Care Unit in Seoul National University Hospital from 1979 to 1982. The total number of patients who were managed in Respiratory Intensive Care Unit in this period was 2.727 and the mortality cases among them were 243 and the overall mortality rate was 8. 9. The mortality rate in 1979 was 19,1% but this was reduced to 4,6% in 1982. The highest mortality rate was recorded by the patients of Department of Neurosurgery. This was 66.7% in 1979 but reduced to 6.3% in 1982. The mean mortality rate under l year of age in this period showed 20.5% which was the highest. The mortality rate in #each sex in the adopted duration showed no significant difference from each other. The ventilators which were used for respiratory support were one kind of pressure regulated mode (Bird) and several models of volume and time regulated type (Bennet MA-1, Emerson, Foregger, Bourns and Searle). The causes of death were low cardiac output, sepsis, brain demage, respiratory failure, and others in order of their prevalence.

<P>Long-term imatinib treatment induces drug-resistant chronic myeloid leukemia (CML) cells harboring T315I gate keeper mutation of breakpoint cluster region (BCR)-ABL oncogenic kinase. However, although cell proliferation is coupled with cellular energy status in CML carcinogenesis, the metabolic characteristics of T315I-mutant CML cells have never been investigated. Here, we analyzed cell proliferation activities and metabolic phenotypes, including cell proliferation, oxygen consumption, lactate production, and redox state in the KBM5 (imatinib-sensitive) and KBM5-T315I (imatinib-resistant) CML cell lines. Interestingly, KBM5-T315I cells showed decreased cell proliferation, lactate production, fatty acid synthesis, ROS production, and down regulation of mRNA expression related to ROS scavengers, such as SOD2, catalase, GCLm, and GPx1. Taken together, our data demonstrate that the lower growth ability of KBM5-T315I CML cells might be related to the decreased expression of glycolysis-related genes and ROS levels, and this will be used to identify therapeutic targets for imatinib resistance in CML.</P>

본 연구는 마이크로파 건조장치를 이용하여 음식물류 폐기물의 재활용 측면에서 음식물 쓰레기(70~100%), 무연탄 (0~30%), 폐플라스틱 (0~30%)의 혼합비율 및 마이크로파 단독건조방식에 따른 운전시간별 건조특성을 평가하고자 하는데 그 목적이 있다. 본 연구에 사용된 음식물류 폐기물은 B시 P사에서 채취하여 사용하였으며, 음식물류 폐기물과 가연성 물질의 균질 혼합 및 건조효율 향상을 위하여 비닐, 어패류 등 이물질을 제거하였다. 또한, 음식물류 폐기물의 건조효율 향상 및 2 mm 이하로 분쇄된 분말 형태의 저품질 무연탄 (Ac ; Anthracite coal) 및 폐플라스틱 (Wp; Waste plastics)을 혼합하여 건조실험을 실시하였다. 마이크로파 건조장치의 전체 크기는 W1,360 mm × L 1,060 mm × H 900 mm, 마이크로파 건조장치의 조사강도는 1 kW이며, 마이크로파 주파수는 2,450 MHz로 제작하였다. 음식물류 폐기물 70%에 무연탄 30%, 폐플라스틱30%을 각각 혼합하여 건조실험을 실시한 결과 마이크로파 건조를 이용한 완전건조 (함수율 10%이하)시 최종 함수율 변화는 운전시간 15분에서 각각 5.4%, 7.8% 로 나타났다. 실험결과 음식물쓰레기에 첨가물을 혼합하였을 경우, 음식물류 폐기물의 재활용 방안으로 마이크로파 공정을 이용한 고형연료의 생산이 충분히 가능할 것으로 판단된다. The main objective of this study is on the development of a method for recycling food waste by using the microwave drying process, as well as the amounts of food waste (70~100%), anthracite coal (0~30%), waste plastics (0~30%). The food waste used in this research was collected at P Company located in B City. For homogeneous mixture of food waste with combustible materials and for better drying efficiency, foreign substances which were vinyl, fish and shellfish were removed. Also, to improve drying efficiency and heating values of food waste, an experiment was carried out to dry a mixture of powder-type low-quality Ac (anthracite coal), Wp (waste plastics), all of which were ground to less than 2 mm. The size of the microwave drying unit is 1,360 mm(W) × 1,060 mm(L) × 900 mm(H), and its projection intensity and frequency were 1 kW and 2,450 MHz was designed. As a result of the experiment, the mixture of food waste (70%) with each anthracite coal (30%), waste plastics (30%) dried using the microwave drying process led to the final moisture contents of 5.4%, 7.8%, respectively, which levels were lowest for full harness (moisture content: less than 10%) and 15-min operating period. The result of an experiment, food waste mixed with other additives was found to produce In sum, as a way for recycling food waste, the microwave drying process seems capable of producing RDF to the full extent.

현대의 생활환경 변화와 산업의 발달로 인해 전력사용량이 해가 갈수록 증가하고 있다. 이러한 전력수요 증가에 맞춰 전기설비의 증설이 필요하지만 설비 증설로 인해 사고시 사고전류의 크기가 증가하고 있다. 이러한 사고전류의 크기는 계통의 주차단기 차단내력을 넘어서게 되고 결국 대용량 차단기로의 교체가 필요하게 되었다. 이러한 상황에서 사고전류의 크기를 제한하여 기존 차단기의 차단내력을 초과하지 않게 해주기 위한 초전도 한류기가 고안되었다. 본 논문에서는 자속결합형 초전도 한류기의 계통 적용시 과도 상태를 분석함으로써 한류기의 적용이 계통 전체에 미치는 영향을 분석하였다. 본 연구에서는 계통 사고의 대부분을 차지하는 1선 지락 사고시(불평형사고)의 사고전류를 분석하였고, 불평형 사고 해석을 위해 대칭좌표법을 이용하였다. 본 초전도 한류기의 구조는 변압기와 초전도 한류소자를 이용한 구조로써 변압기 1차측 코일의 권수를 증가시킴에 따라서 각 대칭분 전류(영상, 정상, 역상 전류)의 크기가 감소하는 것을 확인할 수 있었다.
