For recent 30 years, the ratio of car possessions is rapidly increased according to economic growth. So, nowadays, most of cities and apartment complexes have suffered from traffic and parking problems. The purpose of this study is to provide proper future parking demand at apartment complex in Daegu city by we get the analysis date of the present parking demand. The method of this study is based on field survey of parking demand at apartment complexes in daegu city. The result of this study is as follows; 1) The parking demand has a limit. 2) The old aged apartment complex has more parking problems than the new apartment complex.

The purpose of this study was to analyze the estimating of parking demand in apartment complexes and was compared the number of vehicle with parking regulations. In this study, parking regulations was highly in large scale residential area, and the other hand small scale was lowly. Moreover, residential area and the number or vehicle were correlated, but residential area and parking regulations ratio were not correlated. Estimating models of parking demand developed in this study, are expected to generate available data in site planning and apartment complexes.

In this study, driver's parking behavior characteristics in C.B.D were analyzed by quantification theory Ⅱ, and the variables deeply correlate with parking behavior. And for developing parking choice model, binary logit model was applied to the case of that choice alternative were legal or illegal parking and on-road or off-road parking, and multinominal logit model that can predicts three alternatives simultaneously was applied to the case of that choice alternatives were on-road, off-road and illegal parking. Parking choice models developed in this study, are expected to generate available data in developing and validating parking policy.

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.

회화나무잎에서 3종의 화합물을 단리하였으며 , 기기분석 결과 hypogallic acid, kaempferol, quercetin으로 각각 동정하였다. 이들 단리 물질의 항산화 활성은 라디칼 소거능으로 측정하였으며, 항산화 활성은 100㎍/㎖의 농도에서 각각 98.2%, 96.2% 그리고 90.2%를 나타내었고 이 중 화합물 1 (hypogallic acid)과 화합물 2(kaempferol)의 경우는 합성 항산화제인 BHT보다 높은 항산화 활성을 나타내었다. From the leaves of S. Japonica, three compounds were isolated and identified as follows : hypogallic acid, kaempferol and quercetin. The free radical scavenging activities of the isolated compounds were 98.2%, 96.2% and 90.2% at 100㎍/ml, respectively. Compound 1 (hypogallic acid) and compound 2 (kaempferol) indicated higher antioxidative activity compared with reference compound, BHT.

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.

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

1. With glass microelectrode technique specific for calcium ion, measurements were made for serum ionized calcium. The calibration curve was linear for pCa(2-4) and the tests were reproducible. 2. For five persons each with normal health and with uremia, serum creatinine above 10㎎/㎗, ionized calcium, total calcium, total protein, albumin, and inorganic phosphate were measured in the sera. The results are as following: 1) There were significant differences in serum phosphate and ionized calcium levels between healthy group and uremic patients. The differences were not significant in total calcium, total protein, and albumin contents. 2) The values of ionized calcium, total calcium, total protein and albumin were scattered, but individually some with uremia had lower values. 3. Preliminary tests for ionized calcium assay gave the experience that the ways of collecting and storing samples would alter the data significantly. 4. It is, therefore, felt that further studies on simplification of the sample handing before the measurement of ionized calcium is desirable.
