김민철(Kim, Min-Choul),이재정(Lee, Jae-Jeong),석민광(Suk, Min-Kwang),이강우(Lee Gang-Woo),손병현(Shon Byung-Hyun) 한국산학기술학회 2009 한국산학기술학회논문지 Vol.10 No.12
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.

This study attempts to recognize various phenomena and issues which are caused by public institution`s CCTV: operational problems, protection of the personal image data, operation of the CCTV integrated control center, and so on. Additionally, this does to explore several solutions to those problems. On the basis of the solutions about CCTV, we suggest policy directions to improve installation process and operational efficiency from various perspectives. To suggest policy directions, we consider various aspects of CCTV which are major issues, laws and guidelines, status of the established CCTV in Seoul through literature review, depth interview about the person in charge of CCTV, professional consultation, and so on. Based on those considerations, we suggest policies to make operational and managerial improvement are as follows: ·founding the department which handles everything about CCTV, ·invigorating the CCTV consultative group, alterating the usage purpose of the CCTV, ·improving the CCTV installation process, ·improving the management of personal image data, ·improving the CCTV-related guidelines. In other perspectives, we suggest solutions to improve personal image data protection system are as follows: ·establishing the personal data protective officer in charge of approval process, ·improving personal image data protecting operation, ·reinforcing regulations on the leaking of personal image data, ·strengthening physical security on the CCTV control facilities. Finally, we suggest establishing scope, stepwise activities, road map to which establish integrated CCTV control center in overall Seoul metropolitan city. We hope that results of this study will help to develop the present state of operational efficiency and to protect the personal image data in Seoul.

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)
