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.

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.

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 optimum design for a dynamic micro-mixer with an oscillating stirrer was performed using Kriging method 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 2.0932, 0.8D and ± 75°, respectively. It was found that the mixing index of the optimal design increased by 88.47% compared with that of the original design.

Dermatomyositis is characterized by progressive, symmetric, Proximal muscle weakness and a nonsuppurative inflammatory myopathy of unknown etiology involving predominantly skeletal muscles. It is also characterized by typical skin lesions. Interstitial lung disease has a poor prognosis when it is associated with dermatomyositis. Organizing pneumonia is a disease in which granulation tissue fills the lumina of terminal and respiratory bronchioles and extends into the distal airspaces. The cryptogenic nature of the process is appreciated in that organizing pneumonia patterns of injury can be seen in secondary forms of the disease (secondary organizing pneumonia). Organizin pneumonia has been reported to occur in 5~10% in dermatomyositis-polymyositis patients Anti-histidyl tRNA synthetase antibody (anti-Jo-1) is a Predictive disease marker that is reported to occur in up to 70% of patients. We describe a 49-year-old male dermatomyosits patient who presented with organizing pneumonia and was found to have negative anti-Jo-1 antibody.

An active micro-mixer, which is composed of an oscillating micro-stirrer in the micro-channel to provide effective mixing was optimized. The effects of molecular diffusion and disturbance by the stirrer were considered with regard to two types of mixer models: the simple straight micro-channel and micro-channel with an oscillating stirrer.

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 (Optimal Latin Hypercube Design) in order to determine the optimal design variables. The design parameters were established as the frequency, the length and the angle of the stirrer. The optimal values were obtained as 1.5754, 0.803D and ±45°, respectively. It was found that the mixing index of the optimal design increased by 83.36% compared with that of the original design.

레트 증후군(Rett syndrome)은 1983년 Andreas Rett에 의해 처음으로 보고되었다. 여성에서 주로 호발하여 다양한 민족에서 발견되는 신경장애 중의 하나이다. 레트 증후군의 가장 특징적인 장애의 양상으로 실행증을 들 수 있으며 성장에 따라 집중해서 보는 듯한 눈을 보이기도 한다. 대부분의 레트 증후군은 자폐, 뇌성마비, 규정되지 않은 발달지체로 오진된다. 레트 증후군의 원인은 유전적 요소가 있는 것으로 보이나 아직가지 확실히 밝혀지지 않았다. 본 증례에서 레트 증후군 환아는 과개교합으로 인한 상악 구개부의 손상을 주소로 내원하였다. 상악 구개부의 손상을 감소시키기 위해 교합판을 제작하여 만족할 만한 결과를 얻었기에 보고하는 바이다. Rett syndrome is a neurological disorder seen almost exclusively in females, and found in a variety of racial and ethnic groups worldwide. First described by Dr. Andreas Rett in 1983. The specific features of the Rett syndrome is apraxia. Most of the Rett syndrome has been diagnosed erroneously to autism, cerebral palsy, and unknown developmental disorders. The etiology of the Rett syndrome is not figured out exactly but it seem to have relation with genetic factors. In this case the patient with Rett syndrome had a chief complaint of the injury of palate due to deep bite. We report this case for the satisfactory result using the bite plane to decrease the injury of the palate due to deep bite.
