도시의 급격한 팽창과 함께 주택부족 현상이 나타나게 되자, 정부는 주택부족 문제 해결을 위해 대규모 택지개발을 통하여 주택보급을 확대시켰다. 이러한 현상으로, 공동주택은 우리나라 전체 주택의 83% 수준을 유지하고 있고, 그 중 아파트가 차지하는 비중은 50%로 꾸준한 증가 추세를 보이고 있다. 이로 인해 아파트의 경우 입주민들의 승용차 보유 증가에 따른 아파트 단지 내 주차공간 부족문제 등 제반 주차 관련 문제가 발생하고 있다. 특히, 주차계획대수 수립 시 교통영향평가의 주차수요예측 중 전용면적을 고려한 주차원단위 산정 방법은 기존 계획보다 세대수는 증가하여도 전용면적이 작아지면 계획주차대수는 감소하는 것으로 나타나, 보다 현실적인 주차원단위 산정이 필요한 실정이다. 이에 본 연구는 공공주택 아파트를 대상으로 현실에 적합한 주차원단위를 산정하고자 한다. 현장조사 및 설문조사를 실시하고, 구득자료에 대한 분석을 수행함으로써, 기존 교통영향평가의 주차원단위 산정 문제점을 도출하였다. 또한, 주차수요예측에 영향을 미치는 요인 선정을 통해 주차원단위 산정모형을 개발하였다. 마지막으로 실제 조사된 아파트 주차원단위 자료를 통해 기존 교통영향평가의 주차원단위 산정과 본 연구에서 제시한 주차원단위 산정모형을 비교 분석하였다. 향후 본 연구에서 개발된 주차원단위 산정모형은 주차장법 기준 정립은 물론 보다 현실적인 주차수요예측 수행에 적극 활용될 수 있을 것으로 판단된다. The rapid expansion of cities led to the shortage of housing in urban areas. The government compensated for this shortage through large scale residential developments that increased the housing supply. The supply of condominium apartments remains above 83% of the entire housing supply, and the proportion of apartments are at a steady increase, at about 50%. Due to the increase, illegally parked cars resulting from the shortage of parking spaces within the apartment complex have become increasingly problematic as they block the transit of emergency vehicles, and heighten the tension among neighboring residents in obtaining a parking space. Especially, the future residents are considered to plan the parking based on the estimated demand for parking. However, the parking unit method utilized to estimate the parking demand accounts for the exclusive use of space, which is believed to be far from the parking demands in reality. The reason for this discrepancy is that, as the number of households decrease, and area of exclusive space is expanded, the planned parking increases. On the other hand, when the number of households increase, and the area of exclusive space is reduced, the planned parking decreases, thus methods to recalculate the parking units based on estimated parking demand is an urgent concern. To estimate the parking units based on condominium apartments, this study first examined the existing research literature, and appointed the field of investigation to collect the necessary data. In addition, field study data and surveys collected and analyzed, in order to identify the problems underlying parking units, and problems regarding the current traffic impact assessment parking unit calculation method were deduced. Through identifying the influential factors on parking demand estimates, and performing a factorial analysis based on the collected data, the variables were selected in relation to the parking demand estimates, to develop the parking unit estimate model. Finally, through comparing and verifying the existing traffic impact assessment parking unit estimate against the newly developed model using collected data, a far more realistic parking unite estimate was suggested, reflecting the characteristics of the residents. The parking unit estimate model developed in this study is anticipated to serve as the guidelines for future parking lot legislature, as wel as the basis to provide a more realistic estimate of parking demands based on the resident characteristics of an apartment complex.

Purpose: BOOP and NSIP also share similar clinical features such as subacute flu-like illness, the finding of bronchoalveolar lavage, the result of pulmonary function test and more favourable outcome than usual interstitial pneumonia(UIP). The author try to compare the HRCT findings of NSIP with BOOP by pattern and distribution of diseases. Materials and Methods: HRCT findings of histopathologically proven NSIP(Group Ⅰ; 6, Group Ⅱ; 7, Group Ⅲ; 2) in 15 patients(5 male, 10 female, age range, 39-69 years; mean age, 53 years), BOOP in 15 patients(6 male, 9 female, age range, 26-76 years; mean age, 52 years) were reviewed retrospectively. Results: The common pattern of the two diseases was admixed consolidation, ground glass attenuation & reticular densities with/without architectural distortion(NSIP; 53.3%, BOOP; 46.7%). The main component of the pattern wan predominantly consolidation(NSIP; 46.7%, BOOP; 73.3%) and ground glass attenuation(NSIP; 40.0%, BOOP;20.0%). Architectural distotion was more provinent finding with NSIP(mild ; 3, moderate ; 4, severe; 2) compared with BOOP(mild; 7, moderate; 2, severe; 0). The predominant overall distribution was lower lung, peribronchovascular & peripheral lung field in both of the two entities(NSIP;73.3%, BOOP; 73.3%). Peribronchovascular involvement was more common with NSIP(100%) than BOOP(80%), whereas peripheral involvement was more common with BOOP(93.3%) than NSIP(80%). Conclusion: The HRCT findings of NSIP and BOOP were similar in pattern and distribution. But NIP manifested more frequently ground-glass attenuation, whereas BOOP showed more frequently consolidation. Architectural distortion was more severe with NSIP than BOOP. NSIP invoved more frequently peribronchovascular space and BOOP were more common in peripheral lung field.

朴吉淳,宋大鎭 제주대학교 1974 논문집 Vol.6 No.-

In this survey we tried to find out how habit, income, and the price of foodstuffs affected the eating habits of the people in Je Ju Do so that the most economical and efficient plan of foodstuffs distribution could be carried out. The results are as follows : 1) The rate of consumption of several foodstuffs (banana, dried persimon, canned fish, canned meat etc. ) decreased markedly when their price doubled. But the rate of consumption of other foodstuffs (soy sauce, bean paste, hot bean paste etc. ) only decreased slightly when their price doubled. 2) when we asked what foodstuffs the people would eat if their food budget was increased 50%, the highest percentage responded that they would eat more rice cakes. Others mentioned rice, barley, wheat flaur, broad, apple, mandarin oranges, pears, eggs, milk, etc. But the increase of these foodstuffs was only slight. The consumption of wine was reduced. 3) The frequency of consumption for some foodstuffs was small while for others it was large.

An active micro-mixer, which was composed of an oscillating micro-stirrer in the microchannel to provide rapid, effective mixing at high flow rates was analyzed. The effects of molecular diffusion and disturbance by the stirrer were considered with regard to two types of mixer models: the simple straight microchannel and microchannel with an oscillating stirrer. Two types of mixer models were studied by analyzing mixing behaviors such as their interactionafter the stirrer. The mixing was calculated by Lattice Boltzmann methods using the D2Q9 model, In this study, the time-averaged mixing index formula was used to estimate the mixing performance of time-dependent flow. The mixing indices of the two models were compared. From the results, it was found that the mixer with an oscillating stirrer was much more enhanced and stabilized. Therefore, an approximate optimization of an active micro-mixer with an oscillating stirrer was performed using Kriging method with OLHD(Optima1 Latin Hypercube Design) in order to obtain a optimum solution. The design parameters were established as the frequency, the length and the angle of the stirrer, and the optimal values were determined to be 1.0346, 0.66D and ±45°, respectively. It was found that the mixing index of the optimal design increased by 88.72% compared with that of the original design.

The twisting and extrusion process of the product with involute helical fin from the round billet is developed by the upper bound analysis. The twisting of extruded product is caused by the twisted die surface connecting the die entrance section and the die exit section linearly. In the analysis, the internal shear surface is defined as the curved twisted plane from the taisting of die surface and the shear work is calculated by the consumption of shear energy The increase rate of angular velocity is determined by the minimization of plastic work. The results of the analysis. It is shown that the angular velocity of the extruded product increases with the die twisting angle, the reduction of area, and decreases with the die length, the friction condition.

Clinical effects of rhG-CSF were investigated in 17 patients receiving chemotherapy for non-Hodgkin's lymphoma. Patients were given G-CSF 2㎍/㎏/day after 2nd cycle chemotherapy for least 14 consecutive days, and clinical and laboratory results were compared to results of the first cycle. Treatment with G-CSF resulted in increase of mean WBC count(952.9±152.2㎜³vs 1882.4±350.4/㎜³) and neutrophil count(212.9±53.0/㎜³vs 841.5±238.0/㎜³), reduced the duration of leukocytopenic days(12.4±1.3 days vs 5.5±1.0 days, WBC count less than 4000/㎜³) and neutropenic days(4.5±0.9 days vs 2.3±0.7 days, neutrophil count less than 500/㎜³), and reduced the duration of neutropenic fever(5.8±1.1 days vs 0.9±0.5 days). The side effects of G-CSF were not so significant. These results demonstrated that G-CSF is safe and useful for the treatment of neutropenia induced by anticancer chemotherapy of non-Hodgkin's lymphoma and reducing the incidence of febrile periods and duration of antibiotic administration.

Carboxylic acids are readily reduced to the corresponding alcohols with borane-THF solution (or diborane) at 0°, whereas with lithium borohydride in THF solution the rate of reaction is very sluggish even at room temperature. In this study the possibility for the direct reduction of carboxylic acids to the corresponding alcohols by lithium borohydirde itself have been investigated, forming the reactive acyloxyborane in situ in the reaction mixture of acyloxyborohydride with methyl iodide. Thus, aliphatic acids were reduced rapidly to the alcohols, however, aromatic acid was reduced in a slow rate at room temperature. And in the reaction of α,β-unsaturated carboxylic acids with this reducing system the rduction on carboxylic group and the hydroboration on double bond were occurred competitively. Amino acid and dicarboxylic acid were reduced cleanly to the amino alcohol and diol, respectively. However, amino dicarboxylic acid was inert to this reducing system.
