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.

Influence of Al2O3 Content and Cooling Rate on Crystallization in Fe2O3–CaO–SiO2–Al2O3 Systems

The behavior of silico-ferrite of calcium and aluminum (SFCA) phases and the influence of sintered ore quality were investigatedusing a confocal laser scanning microscope to understand how the Al2O3content of iron ore affects the sintered orestructure and the crystallization behavior of SFCA in a Fe2O3–CaO–Al2O3–SiO2 pseudo-quaternary system. The experimentalresults were used to inform simulations of the heterogeneous dynamic behavior in response to the rapid temperature changesand various chemical compositions typically encountered in actual sintering processes. Increasing the Al2O3content in theFe2O3–CaO–Al2O3–SiO2 pseudo-quaternary system led to the hematite content decreasing, which affects the reducibilityof the sintered ore. The correlation between the creation of SFCA and the cooling effect associated with varying the Al2O3is discussed in detail.

본 연구는 지리산국립공원 심원계곡 생태경관 복원공사지역의 모니터링 결과를 분석하여 체계적인 복원관리를 도모할 수 있는 기초자료를 확보하는데 그 목적이 있다. 복원사업이 완료된 2017년도에 식생 모니터링을 위한 조사구 12개소와 대조구 4개소를 설치하였고, 2017년과 2020년의 상대우점치, 종다양도지수, 유사도 등의 변화를 분석하였다. 복원사업 시 수목이 식재되었던 조사구는 종다양도지수가 0∼1.4552로 나타났고, 대조구와의 유사도지수에서는 1개 조사구가 1.32%로 분석된 것을 제외하고 모두 0%로 나타났다. 조사구의 종다양도지수 및 유사도지수가 매우 낮은 것은 복원사업 시 식재된 수목이 고사하거나 멧돼지 피해, 유수에 의한 침식으로 유실되는 등의 영향으로 판단되었다. 반면 복원사업 시 수목이 식재되지 않은 미식재 조사구는 종다양도지수가 0.9538∼2.3222로 나타났고, 유사도지수는 최대 8.33%까지 분석되었다. 국립공원 생태경관 복원공사지역의 복원 공법 개발을 위한 장기 모니터링과, 미식재 조사구의 천이과정을 분석하는 지속적인 연구가 필요하다. This study aims to obtain basic data for systematic restoration by analyzing the monitoring results of the Shimwon Valley Ecological Landscape Restoration Project area in Jirisan National Park. In 2017, when the restoration project was completed, 12 monitoring plots and 4 control plots were installed for vegetation monitoring, and changes in the relative dominance, species diversity index and similarity between 2017 and 2020 were analyzed. The species diversity index of the surveyed areas where trees were planted during the restoration project was 0-1.4552, and the similarity index with the control group was 0% except for one survey area at 1.32%. The very low species diversity index and similarity index in the survey areas were attributed to the loss of trees planted during the restoration project due to death, damage by wild boars, or erosion by running water. On the other hand, the species diversity index was 0.9538-2.3222 in the monitoring plot where no tree was planted, and the similarity index was analyzed to be as high as 8.33%. It is necessary to continue the long-term monitoring for the development of ecological landscape restoration methods in the national park and analysis of the succession in monitoring plots where no trees were planted.

Infective endocarditis is a very rare cardiac manifestation of salmonella infection, and splenic infraction is a rare noncardiac complication. We describe a case of Salmonella enterica serpvar Typhi bacteremia which was complicated by infective endocarditis with multiple splenic infractions in a previously healthy 47-year-old female. She didn't have any history of foreign travel. The isolate of Salmonella enterica serovar Typhi was susceptible to cephalosporins, aminoglycosides, quinolones but resistant to ampicillin. After 3 weeks of intravenous and oral therapy with ciprofloxacin, follow up transthoracic and transesophageal echocardiography showed no vegetation. In addition, follow up abdominal CT showed decreased size of splenic infractions. The patient was treated with 2 weeks of intravenous and 4 weeks of oral ciprofloxacin, and was cured without sequelae or relapse for 6 months follow-up.

To evaluate the clinical efficacy of ciprofloxacin (CFX) on treatment of the pigs with respiratory diseases or diarrhea. CFX at various dosages were administered intramuscularly to the diseased pigs selected from the pig farms located in Chungnam province. One hundreds and fourteen heads of pigs with respiratory diseases were divided into five groups and CFX at 0.25, 0.5, 1.0 (= 2.5mg CFX/Kg B.W.) and 2.0 doses were administered i.m. for 5 days. The recovery rates were found 31.8%, 73.9%, 91.3% and 92.0%, respectively, being higher than that of the untreated control group (19.0%). The mortality of the treated groups were 0%, that is lower than that of the control (9.5%). Seven kinds of bacteria were isolated from the respiratory organs of 86 pigs, and 34 (39.5%) of 86 pigs showed the complicated infection. In analyzing by the pigs infected with a single pathogen as P. multocida; A. pleuropneumonia. Staphyloccus spp. or Mymplasma spp., the recovery rates were 0∼66.6% at 0.25 dose, 66.6∼100% at 0.5 dose and 100% in all of 4 pathogens at 1.0 to 2.0 doses. At 0.25 dosage the pigs infected with A. pleuropneumonia showed the lowest recovery rate. One hundreds and twenty two heads of pigs with diarrhea were divided into five groups and CFX at 0.25, 0.5, 1.0 (= 2.5mg CFX/Kg B.W.) and 2.0 doses were administered i.m. for 5 days. The recovery rates were 29.1 %, 40.0%, 80.0% and 88.0%, respectively. The mortality of the treated groups were 0∼8.3%, being much lower than that of the control. Four kinds of bacteria were isolated from the fecal specimens of 94 pigs, and 84 (89.0%) of 94 pigs showed the complicated infection.

von Willebrand's disease (vWD) is the most common autosomal-dominant inherited disorder resulting from a quantitative or a qualitative defect of von Willebrand factor (vWF). The most diagnostic pattern is the combination of a prolonged bleeding time, a reduction in plasma vWF concentration, a parallel reduction in ristocetin cofactor activity, and reduced factor Ⅷ activity, In this case, ristocetin-induced platelet aggregation data were compatible with that of vWD. Bleeding times were prolonged over 4 minutes, vWF antigen levels were 45%. vWF ristocetin cofactor activities were 0~1% and factor Ⅷ levels were 31%, when compared to the normal control. We report the case of a family with vWD. characterized by a quantitative defect in vWF
