산업단지에서 발생하는 액상폐기물(폐유와 폐유기용제)을 고온반응기에서(온도 1,250~1,400℃, 압력 1기압) 연소시키면서 연소 특성, 유해물질 분해정도 및 연소 후 배출가스 특성 등을 살펴보았다. 산소와 폐기물의 질량비 (O₂/waste mass fraction)가 1.53 이하로 줄어들 때 반응기는 산화분위기에서 환원분위기로 전환되었고 연소 후 배출가 스는 NOx 배출량이 감소하고 합성가스의 발생비율이 증가하였으며 BTEX류는 99.99%이상 분해되는 것으로 나타났 다. 본 연구에서 제안한 시스템 및 조업조건 하에서 고농도의 액상폐기물(폐유와 폐유기용제)을 처리한 결과 미량 오 염물질의 배출농도는 매우 낮은 값을 보여 액상폐기물의 처리에 적합한 것으로 판단되며 또한 연소 후 합성가스도 연료로 활용할 수 있을 것으로 사료된다. This study was investigated to determine the combustion characteristics, decomposition efficiency, and the flue gas concentrations after combustion in the high temperature reactor(1,250~1,400℃, 1 atm) for the liquid wastes(waste oil and waste solvent) generated from the industrial complex. The concentration of nitrogen oxide(NOx) is decreased and the synthetic gas is increased when the mass ratio of O₂/waste is about 1.53 because the reaction condition was changed to reduction state. And BTEXs(benzene, toluene, ethylbenzene, xylene) are decomposed more than 99.99%. If the highly concentrated liquid waste (waste oil and waste solvent) is treated under the operating conditions suggested by this study, our treatment method for the liquid waste was found to be proper because of the contaminants emission concentration is very low. In addition, the synthetic gas after combustion can be used as an alternative fuel.

The space of public libraries has been changed in the direction of supporting user satisfaction and various activities, focusing on the role of data preservation and education. However, unlike before, the use of space is not suitable to accommodate various needs, such as the disappearance or reduction of existing space to provide services and programs. In particular, a method of calculating the size according to the number of people within a certain range or calculating the size by referring to the average size of other nearby libraries was proposed. In this study, factors influencing the number of users were derived through the analysis of previous studies. The factors derived from previous studies are limited to the physical factors necessary to calculate the size at the pre-planning stage, so the influencing factors were supplemented and added to four categories: education, culture, commerce, and transportation facilities. As of 2019, statistical data from 33 public libraries in Busan were analyzed to collect data within 0-1km walking distance, and hierarchies were classified according to the number of visitors by region to derive influencing factors that affect visitors regardless of size. The analysis method was conducted in two ways through impact analysis and regression analysis according to the visitors award/middle/lower hierarchy. As a result of the study, factors influencing high school libraries such as the number of high school students, parks, and movie theaters were derived. Through the results of these studies, it is expected that a hypothesis can be established based on the physical factors of the Busan Library and used to establish a calculation formula for calculating the size of the public library in the future.

공석민,오동욱,안호연,이현구,이용주,Kong, Suk-Min,Oh, Dong-Wook,Ahn, Ho-Yeon,Lee, Hyun-Gu,Lee, Yong-Joo 한국터널지하공간학회 2016 한국터널지하공간학회논문집 Vol.18 No.6

도심지에서 지하철과 같은 터널의 증가에 따라 특수한 설계, 및 시공 방법이 제안되어 왔다. 터널 붕괴 사고는 막대한 인명, 재산 피해를 가져오기 때문에 터널 굴착 및 주변지반의 거동을 관측하고 분석하는 작업은 매우 중요하다. 하지만 매번 현장시험을 하기에는 경제적인 측면에서 비현실적이다. 따라서 현장시험의 단점을 보완하고, 보다 정밀한 결과를 도출하는 연구가 지속적으로 발표되어 왔다. 본 연구는 군말뚝과 터널 사이 이격거리에 따른 2-arch 정거장 굴착 시 주변 지반의 거동을 측정하였다. 실내모형시험을 위해 trapdoor장치를 고안하였으며, 터널굴착은 2-arch 터널의 체적손실(VL)을 증가시킴으로써 모사하였다. 또한, 근거리 사진계측 및 이미지프로세싱을 통해 지반의 거동을 관측하였으며, 수치해석을 통해 실내모형시험의 결과와 비교하였다. Special tunnel design and construction methods have been suggested due to developments of subway and tunnel. Collapse accidents of tunnel bring enormous damage. So, observation and analysis for the safety of tunnelling and behaviour of surrounding ground are important. But, it is not economical to implement the field test in every time. Therefore, this study has measured ground behaviour due to excavation of 2-arch tunnel station according to offset between grouped pile and tunnel by laboratory model test. For the model test, trapdoor device was adopted. Tunnelling is simulated by volume loss of 2-arch tunnel. Ground displacements are observed by close range photogrammetric method and image processing. In addition, these data are compared with numerical analysis.

터널 정거장 형상에 따른 군말뚝 하부 굴착 시 지반거동 연구

공석민,오동욱,이종현,이용주,Kong, Suk-Min,Oh, Dong-Wook,Lee, Jong-Hyen,Lee, Yong-Joo 한국터널지하공간학회 2018 한국터널지하공간학회논문집 Vol.20 No.1

Tunnels are widely used for special purposes including roads, railways and culvert for power transmission, etc. Its cross-section shape is determined by uses, ground condition, environmental or economic factor. Many papers with respect to behaviours of adjacent ground and existing structure tunnelling-induced have been published by many researchers, but tunnel cross-section have rarely been considered. A collapse of tunnel causes vaster human and property damage than structures on the ground. Thus, it is very important to understand and analyse the relationship between behavoiurs of ground and cross-section type of tunnel. In this study, the behaviour of ground due to tunnel excavation for underground station below the grouped pile supported existing structure was analysed through laboratory model test using a trap-door device. Not only two cross-section types, 2-arch and box, as station for tunnel, but also, offset between tunnel and grouped pile centre (0.1B, 0.25B, 0.4B) are considered as variable of this study. In order to measure underground deformation tunnelling-induced, Close Range Photogrammetry technique was applied with laboratory model test, and results are compared to numerical analysis. 터널은 도로, 철도, 지하철과 같은 교통의 통로이자 수로, 전력구, 비축기지와 같은 특수목적을 위해 널리 활용되고 있으며, 터널의 사용 목적, 주변 지반조건 및 경제성에 따라 다양한 터널 형상으로 시공되고 있다. 이에 대해 기존 터널과 주변지반 및 구조물에 관한 연구는 꾸준하게 발표되었으나 단일 형상에 대해 터널굴착 시 주변 지반과 구조물의 거동을 분석한 연구들이 대다수이다. 터널의 붕괴사고는 지상 구조물의 붕괴사고 보다 막대한 인적, 물적 손실을 가져오기 때문에 터널 굴착 및 주변지반의 거동을 관측하고 분석하는 작업은 매우 중요하며, 단일 형상이 아닌 다양한 터널 형상에 대한 연구가 필요할 것으로 판단된다. 따라서, 본 연구는 trapdoor장치를 이용한 실내 모형시험을 통해 군말뚝 하부에 터널 정거장 굴착 시 주변지반의 거동을 측정하였다. 이때 터널 정거장 형상의 단면을 arch와 box 형태로 제작하였으며, 각 터널 정거장 형상 별 0.1B, 0.25B, 0.4B로 터널과 군말뚝 간 이격거리를 다르게 하여 다양한 조건에서의 지반거동을 분석하였다. 또한, 근거리 사진계측 및 이미지프로세싱 기법을 통해 지반의 거동을 관측하였으며, 유한요소 수치해석을 통해 실내 모형시험, 근거리 사진계측의 결과와 비교 분석하였다.

ITP는 원인을 찾을 수 없이 혈소판의 수적 감소로 발생되는 질환으로 혈소판이 30,000/μL 이하이거나 출혈이 있는 경우에 치료가 요구된다. 부신피질호르몬, 비장절제술이 대표적인 치료 방법이며 이에 반응이 없을 경우 면역억제제, 혈장반출법, 고용량 면역글로불린, 다나졸, 콜키친 등의 다양한 치료 방법을 시도할 수 있으나 반응이 매우 낮은 반면 부작용이 문제가 된다. Rituxi-mab은 B 림프구의 표면에 발현되는 CD20 항원에 특이적인 인간-생쥐 키메라 단클론항체로 만성 ITP에서 반응이 좋은 것으로 보고되고 있다. 저자들은 기존의 치료에 반응이 없던 불응성 ITP로 계속되는 질출혈과 폐출혈이 있었던 32세의 여자 환자에게서 Rituximab을 사용하여 치료에 성공한 증례를 경험하였기에 보고하는 바이다. Idiopathic thrombocytopenic purpura (ITP) is an immune disorder in which platelets are opsonized by autoantibodies and prematurely destroyed by the reticuloendothelial system. Among adult patients, approximately 25~30% develop a chronic disease that will become refractory to corticosteroids and splenectomy, as well as other available agents. Rituximab is a human-murine chimeric monoclonal antibody specific for the CD20 antigen, found on the surface of B lymphocytes. It acts via complement-dependent cytotoxicity, antibody-dependent cellular cytotoxicity, and induction of apoptosis. We report a case of 32-year-old female with severe, refractory ITP, who presented with generalized petechiae, intractable vaginal bleeding, and pulmonary hemorrhage. After multiple conventional therapeutic trials, the patient was finally placed on weekly infusion of rituximab that resulted in a favorable response. (Korean J Med 69:S934-S938, 2005)
