Diabetic foot infection is one of the important complications in patients with advanced diabetes mellitus. Limb threatening infections such as osteomyelitis, abscess, and necrotizing fasciitis are frequently accompanied by the disease. Non-tuberculous mycobacterium (NTM) is a rare causative organism of diabetic foot infection. Thus, if one is not suspicious or meticulous, infection due to NTM will be easily overlooked and this will result in delayed diagnose and treat. Therefore, it is necessary to consider NTM as the causative organism if the wound does not respond to the conventional antibiotic treatment and the culture from the adequately obtained specimen reveals atypical acid-fast bacilli. We present a case of diabetic foot infection with osteomyelitis and abscess due to Mycobacterium mageritense, one of the rapid growing mycobacteria, that was successfully treated with surgical debridement and appropriate antibiotic treatment.

Effects of ditiazem on staircase phenomenon were investigated in rabbit papillary mucles partially depolarized by 19mM K-Tyrode solution. The following results were obtained: 1. Contractile forces were increased in paralle with the increase of stimulation frequencies from 0.2㎐ to 2㎐ in the muscle preparation partially depolarized around -50㎷ by 19mM K-Tyrode solution. 2. Contractile forces induced by various frequencies of electrical stimulation were markedly changed in high Ca^2+ solution, while those were not remarkable in low Ca^2+ solution. 3. The relationship between developed tension and stimulation frequency were negatively inverted in low concentration of diltiazem(0.05 and 0.1㎎/l). 4. Amplitudes of action potentials were reduced in administration of low calcium and ditiazem which affected calcium flux during action potential. 5. Durations of action potential were prolonged in low calcium solution and those were shortened in low concentration of ditiazem. 6. Amplitudes of action potential in ditiazem-treated 19mM K-Tyrode solution were continuously reduced by change in stimulation frequencies from low to high rate. Above results suggests that amplitudes of action potential closely related with contractility of rabbit papillary muscle in 19mM K-Tyrode solution and decreased influx of calcium during action potential could be related with nagatives staircase phenomenon.

삼일열 말라리아는 국내에서 재유행하고 있는 감염질환으로, 일반적으로 양성의 임상경과를 거친다. 저자들은 특이한 질병력이 없이 건강하였던 젊은 성인이 국내에서 삼일열 말라리아에 걸린 후 다기관기능부전과 폐출혈으로 사망한 증례를 경험하였다. 환자의 중증 임상경과를 설명할 만한 특이한 인자가 발견되지 않았다. Vivax malaria is a re-emerging infectious disease in Korea with cumulating 19,416 cases as of December 2003 since 1993. Vivax malaria is generally a benign disease with few severe complications. Even in the worldwide literature, there are only small number of case reports on severe complications. We experienced a fatal vivax malaria in a previously healthy young adult with severe multi-organ failure and fatal massive pulmonary hemorrhage. The patient presented with abdominal pain and shock. There were splenic hemorrhage, disseminated intravascular coagulation, oliguric acute renal failure requiring dialysis, and pulmonary hemorrhage leading the patient finally to death. The initial parasitemia was 2,046/μL. Thin smear and PCR revealed only Plasmodium Vivax. There was no explainable cause of death except for the only serological suggestion of Mycoplasma pneumoniae infection without correlating clinical evidence. This is a first case of fatal vivax malaria in Korea since its re-emergence in 1993. Further case monitoring is needed to define whether this is a index case or an isolated one.

Distribution of indicator species of copepods and chaetognaths were studied as an indicator species of water mass in the southeastern area of the Yellow Sea. Undinula darwini, Lucicutia flavicornis, Pleuromamma gracilis, Euchaeta resselli, Euchaeta plana and Sagitta enflata were found to be reliable indicator species for determining warm water mass. Of these species, E. plana and E. russelli have a weak tolerance on the low temperature. Sagitta crassa was indicator species of neritic waters: Sagitta bedoti was that of mixing waters. Centropages agdominalis represented neritic cold waters. In February U. darwini, L. flavicornis, P. gracilis, E. russelli, E. plana and S. enflata occurred in the western waters of Cheju-Do where warm waters over 14℃ occupied. Centropages abdominalis occurred in the northern area beyond Chindo with water temperature less than 10℃. E. plana, E. russelli and S. bedoti were found at the regions between Cheju-Do and Chindo where the water temperature was 12∼14℃ corresponding to the mixing waters. Based on cluster analysis and T-S diagram in February three different water masses were identified from the south to the north. In August, water masses were analyzed at two different layers, 0∼20m and 20m∼bottom layers, separated by thermocline depth. In 0∼20m layer, E plana and E. russelli were found from the western waters of Cheju-Do to Daehuksando. In 20m∼bottom layer, E. russelli and E. plana occurred at the northwestern waters of Cheju-Do with the water temperature warmer than 12℃. C. abdominalis was found at the northern area beyond Chindo. Based on the cluster analysis and T-S diagram in August three different water masses at 0∼20m and 20m∼bottom layers were identified from the coast to the offshore. C. abdominalis was found at the adjacent water of Chindo at 0∼20m layer and the northern area beyond Chindo at 20m∼bottom layer. This fact suggested that the cold water mass existed at the adjacent waters of Chindo in summer.

The purpose of this study is to find a tendency of choice of housing types about 132 householders in Daegu city. In case of this study, we can know a pont of difference between needs of housing end users and those of housing suppliers. According to the results of this study, 45.45% of households want detached houses and 45.45% of householders want apartment housing. But, the construction ratio of detached houses is decreasing day by day. So, it needs a change of housing supply system which was partial toward apartment housing

In this paper we fuzzyfy the solutions of the linear second order ordinary differential equations with constant coefficients and define fuzzy solutions to O.D.E. appropriately. Moreover, we compare the fuzzified solutions with the classical(or crisp) solutions. For this comparison, we estimate the how much the fuzzy solutions diffuse.
