산업단지 및 주거지역에 대한 환경대기 중 주요 악취물질의 농도특성에 관한 연구 -안산시 반월공단을 중심으로-
최여진,김기현,전의찬 한국지구과학회 2006 韓國地球科學會誌 Vol.27 No.2
In this study, the distribution patterns of major odorous compounds in ambient air were investigated in the areas surrounding the Ban-Wall industrial complex of Ansan, Korea (Aug. 2004 to Sep. 2005). The results indicated the environmental significance of several major odorous compounds which include carbonyl compounds, reduced sulfur compounds (RSC), and volatile organic compounds (VOC). When the results were compared on a diurnal basis, the afternoon time concentration of most odorous compounds were notably higher than their morning time counterparts. It also indicated that the odor concentrations differed greatly, in terms of spatial grouping scheme of data sets, such as between industrial area and non-industrial area. The comparison of spatial patterns indicated that the concentrations of most of the compounds at the industrial area were maintained at high concentration levels, compared to the surrounding areas. The overall results of this study thus suggest that the distribution of odorous compounds in a large industrial complex can exhibit a unique pattern of their own. 본 연구에서는 악취민원이 빈발한 경기도 안산시에 위치한 반월공단의 주거지역과 공단지역 등을 중심으로 주 요 관리대상으로 설정된 악취성분들에 대한 환경대기 중 농도분포 특성을 2년여 기간동안 6차례에 걸쳐 조사하였다. 이들의 거동을 이해하기 위해, 시간적(오전과 오후) 및 공간적(공단 내외부의 위치) 기준으로 분포특성에 대한 비교를 시도하였다. 그 결과, 오전시간대에 비해 오후시간대에 고농도 분포가 현저하게 높은 것으로 나타났다. 이와 유사하게 공간적인 기준으로 비교한 결과도 공단 내부에서 관측한 결과에서 대부분의 성분들이 고농도를 유지하는 것을 확인할 수 있었다. 본 연구의 결과는 안산시 주변 및 공단지역의 환경대기 중에 존재하는 악취성분들이 시간적 및 공간적 기 준으로 다양한 분포특성을 취한다는 것을 보여주었다.
건축설계 과정에서 융합적 사고능력 향상을 위한 국내 대학의 BIM 교육과정 운영실태 분석과 교육전략 제안
최여진 한국융합학회 2019 한국융합학회논문지 Vol.10 No.12
In order to meet the needs of integrated design process in architect industry, BIM(Building Information Modeling) education in university is urgently needed. However, the investigation of the current status of BIM education at 60 universities shows that most universities do not offer BIM education at all, or opened only one regular course for BIM education. The survey on BIM education for students shows that non-curricular activities brought bigger educational achievements than regular courses. Considering these findings and the practical restrictions of the universities, and through evaluation and feedback from professors as educational providers and working architects as professional users, the desirable strategy for BIM education in architect design was able to be suggested, which is consisted of regular curriculum of two courses and 40 hours non-curricular activities. 건축설계 실무에서 디자인 통합설계에 대한 요구에 대응하기 위해서 BIM(건축정보모델링) 교육이 절실함에도 불구하고 한국건축학교육인증에 참여하고 있는 60개 대학 건축학과의 교육과정 운영 실태를 전수 조사한 결과 대부분의 대학에서는 BIM교육을 전혀 제공하지 않거나 단 1개의 정규교과목만 개설하고 있는 것으로 나타났다. 그리고 BIM 교과목 수강과 비교과 활동을 수행한 학생들을 대상으로 설문조사한 결과 정규교과목보다 비교과 활동을 통해 유효한 교육성과를 더 많이 얻었던 것으로 나타났다. 이러한 조사 결과와 국내 교육기관의 BIM 교육 프로그램 분석결과, 그리고 대학의 현실적인 제약사항을 모두 고려하고 교육 공급자인 대학교수와 사용 주체인 실무 건축가의 평가 및 의견수렴을 거쳐 건축설계 과정에서 융합적 사고능력 향상을 위해 교과과정 및 비교과활동으로 구성된 대학의 BIM 교육 전략을 제안하였다.

In this study, the concentrations of major reduced sulfur compounds (H₂S, CH₃SH, DMS, and DMDS) were determined from ambient air in a monitoring station located in the mid-eastern area of Seoul. Measurements of sulfur species were conducted by the combination of on-line air sampling, thermal desorption, and capillary GC/PFPD analysis. A total number of 143 hourly samples were collected in the two time periods set between June and July 2003. The mean concentrations of four sulfur species measured in the whole study period were found on the order: DMS (535±183H) > H₂S (47±10) > DMDS (35±22) > CH₃SH (6.19±29.4 pptv). The results of this study show that the concentrations of DMS at the study area are generally higher than those reported previously in the oceanic environments, while those of other sulfur species are not easy to compare with due to the lack of data. The H₂S concentrations were generally higher during the daytime than the nighttime, whereas those of others generally exhibited a reversed diurnal pattern. The overall results of our study suggest that the distribution of major reduced S compounds should be controlled by diverse processes in the urban area.

In the present work, the distribution characteristics of ambient volatile organic compounds (VOCs) were investigated at high temporal resolution from a monitoring station located in a mid-eastern area of Seoul. A total number of 587 samples were collected during December 2002 to January 2003. The measurements of VOC were conducted by a combination of on-line air sampling and thermal desorption unit (TDU) coupled with capillary GC/FID analysis. A total of five aromatic compounds (BTEX: benzene, toluene, ethyIbenzene, m, p-xylene, and o-xylene) were, measured routinely at hourly intervals during the whole study period. The mean concentrations of BTEX measured in our study period were found in the order: toluene (8.99±5.38ppb)>benzene(0.92±0.52ppb)>m, p-xylene (0.51±0.34ppb)>o-xylene(0.48±0.35ppb)>ethyl benzene (0.43±0.32ppb). The BTEX concentrations were generally higher during the daytime than the nighttime, exhibiting certain patterns on a weekly basis. Results of our analysis indicate that the unusually high concentrations of toluene, while showing good correlations with other VOCs, can be a good indicator of air pollution in the study area.
