The effects of air velocity and excess air on combustion characteristics were studied in a fluidized bed combustor. The domestic low-grade anthracite coal with heating value of 2010 ㎉/㎏ and the imported bituminous coal from Australia with heating value of 6520 ㎉/㎏ were used as coal samples. The combustion characteristics of mixed fuels in a fluidized bed combustor could be interpreted by pressure fluctuation properties, ash distribution and gas emission. The properties of the pressure fluctuations, such as the standard deviation, cross-correlation function, dominant frequency and the power spectral density function, were obtained from the statistical analysis. From this study, the combustion region increased with increasing air velocity but decreased with excess air due to combustion characteristics of anthracite and bituminous coal.

Currently, the consumer pattern is directed to small quantity and high variety these days. World market is led by technological innovations and changes rapidly. To survive in this environment, the raising of small and medium enterprises is highly desirable. In the context of nationwide restructuring, competitive medium and small industries which are in good financial status should lead the nation's economy. But general ignorance of the safety issues could lead to a miss management of this industry in this field. In this study, actual condition and improvement of safety management are as follows; We have to 1) find out the factors which endangers this industry, and set a proper guideline for safety management. 2) encourage safety management of these industries by themselves, and advertise and provide technical support for using PC and internet. 3) set a higher standard of safety issue when accrediting a prospective medium and small industry, and have a firm control of this issue once accredited. 4) supply more governmental financial aids to terms of safety issues for medium and small industries.

In recent years, a number of metal machine parts, in the field of the car manufactures and electronic goods for home, have been replaced by nylon-6 in order to weight, cost, and a period of process of manufacture. It's because nylon-6 materials as an industrial material have higher economical and productive advantage than the metalic ones. However, in domestic injection manufactures, there are few data on fiber glass synthetic on nylon-6. It is said that plastic in process of manufacture using the same injection materials make their results different in large scale according to fiber glass synthetic rate conditions. In this study, we have studied effects of the glass fiber synthetic rate on the characteristics of fatigue failure for nylon-6.

Epidural and subarachnoid narcotics have raised new possibilities for selective blockade of pain transmission at the spinal cord level. However, it must still be regarded as an experimental technique until detailed pharmacological and physiological data are available, since many reports have treated the development of respiratory arrest which may be related to the dynamics of CSF flow. We experienced 2 cases of respiratory arrest after intrathecal injection of 2mg morphine. One patient developed respiratory arrest at approximately 5 1/2hours after intrathecal morphine and the other at approxmately 12 1/2hours. Those respiratory arrests were completely reversed with naloxone hydrochloride without interfering with the analgesic effect of the drug.

Haemophilus aphrophilus is a fastidious gram-negative bacillus found in mouth of normal individuals. Though H. aphrophilus infection is quite rate, it includes such serious ones as endocarditis and brain abscess. The authom isolated H. aphrophilus from five patients with the diagnosis of lung abscess, conjunctivitis, brain abscess and facial masticator space abscaa Two of the patients died. Three of the patients also yielded other species of bacteria from the same specimens. One of the isolate was intermediately susceptible to amikacin and resistant to tobramycin, indicating the necessity of a routine susceptibility test in order to select the proper antimicrobial agents. Since FS. Aphrophilus can be diffetentiated from other similar organisms by morphological and biochemical chamcteristics, one should determie the possibility of this organisrn when faptidious gram-negative bacilli are isolated from blood or from sites adjacent to upper respiratory tract.

This paper presents the preliminary results on the application of optical fiber sensor(OFS) for the measurements of discharging signal and degradation in insulation oil such as transformer and silicone oil. An OFS system using a Mach-Zehnder interferometry technique was built to detect attenuation of acoustic signal produced by discharging. Simultaneous measurements were made of electrical signal and OFS signal from discharge. It was found that the arcing signal produced by needle-sphere electrode system could be detected by OFS installed in an oil bath. With increasing OFS distance from an arcing spot, the attenuation of acoustic signal became greater. From the results of sound attenuation for various insulation oils, the linear relationship was observed between the attenuation signal and viscosity in log scale. Details of these results are discussed.

수용액상에서 몰리브덴산암모늄염과 인산의 반응으로 P/Mo=1.0의 비율을 가진 몰리브덴인산화물을 제조하였다. 제조한 몰리브덴인산화물을 촉매로 사용하여 상압하에서 3-피콜린의 가암모니아 산화반응을 수행하였으며, 3-피콜린, 산소, 암모니아의 각각의 분압과 반응온도의 영향을 살펴보았다. 본 실험조건하에서 촉매활성은 반응 300시간까지는 계속적인 활성증가가 있었고 이후 500시간까지 안정상태를 유지하였다. 안정화 상태에서의 3-피콜린의 반응 속도식은 -r=kP₃_pP^0_(NH₃) P^γ_(o₂)[γ=0.2;0.25≤P_(o₂)(㎪)≤:5γ=0;5≤P_(o₂)(㎪)]으로 3-피콜린에 대해서는 1차, 암모니아에 대해서는 0차이었으며, 산소에 대해서는 0차와 0.2차로 구간에 따라 차이가 있었다. 3-피콜린의 전환율 증가에 따라 3-시아노피리딘의 선택도가 증가하였으며 동시에 아미드와 산의 선택도는 감소하였다. Molybdenum phosphate(P/Mo=1.0) has been synthesized with ammonium molybdate and phosphoric acid under aqueous solution. The kinetics of ammoxidation of 3-picoline over the molybdenum phosphate catalyst were investigated with the variation of reaction temperature and partial pressure of 3-picoline, oxygen, and ammonia, respectively at atmospheric pressure. The catalytic activity was increased until 300 hrs on stream and then maintained until 500 hrs on stream under our experimental conditions, At the steady-state conditions, the rate equation of 3-picoline ammoxidation was shown as -r=kP₃_pP^0_(NH₃) P^γ_(o₂)[γ=0.2;0.25≤P_(o₂)(㎪)≤:5γ=0;5≤P_(o₂)(㎪)]. The correlation between the conversion of 3-picoline and the selectivity of 3-cyanopyridine had the proportional relationship. As the selectivity of 3-cyanopyridine increases, the selectivity of amide and acid decreases.

Background/Aims: Colonic ischemia is recognized as the most common vascular disorder of the intestines in the elderly. The severity of the disease may vary considerably with the prevalent benign transient forms, being amenable to conservative treatments and the severe gangrenous forms, requiring surgery. Correct diagnosis is usually made after the ischemic episode is over and colonic ischemia is frequently misdiagnosed. The aim of this study is to identify the clinical patterns and prognostic factors of ischemic colitis. Methods: We found 60 patients with nonoccusive ischemia of the large intestine, We analyzed age, sex, symptoms, signs, associated disease, location, endoscopy, hematologic, histologic, radiologic finding and treatment, retrospectively. Results: The mean age was 60.2±6.3 years. The most common symtoms were abdominal pain or bloody diarrhea. The most common sign was diffuse abdominal tenderness. The most common hematologic findings were anemia and leukocytosis. Associated medical illnesses wer diabetes, rhematoid arthritis and cerebrovascular accident, et al. Both computed tomography (CT) and endoscopy were useful diagnostic tools. The most common involved site was sigmoid colon. 46 patients were treated conservatively and 14 patients were managed surgically. Conclusions: Male gender, those with rebound tenderness, severe anemia, right or total colon involvement as well as rheumatoid arthritis had a poor prognosis. Both CT and endoscopy were useful in predicting prognosis.
