미세먼지입자의 정전기력 부여에 따른 여과집진의 성능특성에 관한 연구
정진도,김진철,정관호 호서대학교 반도체제조장비국산화연구센터 2000 학술대회 자료집 Vol.2000 No.1
일반적으로 에어로졸 상의 고체입자에 대한 분리기술은 크게 전기집진기술과 여과집진기술, 습식기술 등으로 나눌 수 있다. 최근 연료의 탈황으로 인해 배출되는 먼지의 비저항성이 높아져 전기집진기술의 효율이 크게 떨어져 여과집진기술로 조금씩 대체되어가고 있다. 그러나 여과집진기술의 경우, Flow Gas 포집기작의 영향이 지배적이지 못한 1㎛ 미만의 입자들에 대한 제어가 효과적이지 못한 단점이 있다. 본 연구에서는 이러한 1㎛ 미만의 입자들에 대해 정진기력을 부여해서 전기적응집에 의한 입자성장을 유도하여 여과집진시에 필터 표면에 Dendrites Structure를 형성하게끔 유도하여 ΔP 증가율을 낮추고자 한다. 이에 따른 직접적인 효과는 탈진회수의 감소로 탈진시 소요되는 동력비의 감소와 탈진시 마모나 파손되는 여과포의 수명연장으로 실제 산업공정에 적용시 운전유지비의 감소효과를 꾀할 수 있을 것으로 사료된다.

공간정보 오픈플랫폼 수출을 위한 해외 국가 유형별 진출전략 수립에 관한 연구
정진도,한선희,이재용 한국지도학회 2014 한국지도학회지 Vol.14 No.2
세계 공간정보 인프라 환경은 급격하게 플랫폼 기반으로 변화하고 있으며, 우리나라가 구축 완료한 공간정보 오픈플랫폼은 세계 각국의 공간정보 인프라 구축을 위한 대안이 될 수 있다. 다만 수출 대상 시장을 확장하고 수출 대상 국가에 성공적인 공간정보 인프라를 구축하기 위해서는 각 국의 국가 특성에 적합한 수출 전략의 마련이 선행되어야 한다. 이를 위해 본 연구에서는 국가 특성을 반영하는 다양한 대리변수들에 대한 전문가 AHP 조사 및 통계 분석을 통해 진출 대상 국가의 우선순위를 산정하였으며, 진출 대상 국가를 각각의 특성에 따라 5개의 범주로 분류하였다. 또한 이를 기초로 하여 수출 전략 수립을 위한 이론적 기반을 제시하였으며, 이론적 기반을 토대로 5개 국가 분류 각각에 대한 공간정보 오픈플랫폼 수출 전략을 제시하였다. World geospatial infrastructure environment has changed dramatically to platform-based over the past years. So our Spatial Information Open Platform is a good alternative to establish geospatial infrastructure of overseas countries. But suitable export strategies of Spatial Information Open Platform for each country must take precedence over all others in order for new market creation and successful geospatial infrastructure establishment. To achieve this, this study set priority target countries through the AHP and statistics of variables which reflect the characteristics of countries, and classify them into five groups by characteristic. Based on this classification, the study draws theoretical framework to establish export strategies, and it also leads to suggest Spatial Information Open Platform export strategies for each class.

천안백석매립장을 중심으로 한 메탄가스 발생량에 관한 연구
정진도,김장우,정인권,배찬열 한국환경과학회 2004 한국환경과학회지 Vol.13 No.7
Most of methane gas result from waste matter in landfill, therefore the persons concerned take an increasing interest in management of gases in landfill. Infrared Gas Analyzer was used to measure components of gases, CH₄,CO₂, O₂, through gas exhausted pipe. To measure amount of the gas flow meter(Portable Hot-Line Current Meter) was used and it was set at right angles with direction of the flow. In this research the total amount of methane gas produced in Beck-Suk Landfill was calculated through FOD method suggested by IPCC. This research found that in Chon-An Beck-Suk Landfill anaerobic resolution was made actively and the amount of methane gas produced there was 54.14%, which is higher than common figure, 50%, in other researches. The components of reclaimed waste matter, especially, organic waste matter can have a great effect of the amount of the greenhouse gases produced in landfill. We can expect that the amount of greenhouse gas will decrease from 2005, when it will be prohibited from carrying kitchen refuse and sludge into landfill.

This research is to determine the level of environmental pollution at a blasting construction area which is the origin of noise, vibration, and suspended particle, and to compare the results with other domestic and international standard data. This experiment is also to find out the effects resulting from blasting construction and to propose a plan that can decrease environmental pollution. The blasting construction area is a factory site which is about one and half million square meter and sewage disposal plant is about ninety thousand square meter. Both were selected as the areas for the tests to be conducted in determination test. The test to determine the level of noise, vibration, and total suspended particle was conducted thirty times around the blasting construction area by comparing measurement results and numerical analysis. However, as the test was not conducted in the laboratory but in the actual blasting construction area, it was not possible to do the test with the same exact conditions each true. Therefore, the test was not ideal as conditions could change from test to test. For the most part, the level of noise was below the standard level of 70dB. Every vibration test was under the standard limitation. For example, a house, 200m away was tested for noise and vibration and the level was found to be under the 0.2 cm/sec which is the standard for specially designed cultural sites., i.e very low level. Also a buried oil pipeline that was 30m away also marked under 2.0cm/sec which is the norm for an industrial area. However, if there were an oil pipeline under the house, the amount of charging gunpowder per hole should be decreased compared to the amount used in the test. The test result for suspended particles under the standard limitation which is 24hour average 300㎍/m² at a distance from blasting wavelength, but at detonator, total suspended particle from the blast origin exceeded the standard limitation. If explosion occurs when it detonates in the hole, most of the energy would be absorbed in the crushing of rocks, but some remaining energy would make noises and vibration inevitable. So the important thing is how to minimize the environmental pollution from the blasting. There should be regulations in order that the standard limitation is not exceeded, and to decrease the environmental pollution from the blasting.

This study was compared each ingredient's local/seasonal change characteristics by analyzing anions and cations, watersoluble ionic components, from the precipitation of Dangjin and Anmyeon-do areas. The samples were collected for 8 months from both spots between the period of April 1, 2002 to November 31, 2002. The precipitation samples were collected continuously through the entire duration of precipitation by using the wet-only automatic samplers. When rain continues to fall over 24 hours or occasionally, we considered those collected from 9 o'clock in the morning for 24 hours as the day's samples. As a method to verify for the reliability of the analyzed data is concerned, we use the ion balance method and the electricity conductance method, was used widely as a way of watching the atmosphere by the WMO (World Meteorological Organization)/GAW (Global Atmosphere Watch). Also, Dangjin and Anmyun-do area confirmed that contains artificial pollutants by analysis of ion concentration data.

골프장건설 전후 임업부문 온실가스 순 흡수량 산정 비교 연구
정진도,김정홍 한국도시환경학회 2010 한국도시환경학회지 Vol.10 No.3
The present research estimated absorption of greenhouse gas in the forestry sector before and after construction of “C”golf course located in “W” city, and comparatively researched by considering a long-term aspect. This study has used an estimation equation of absorption of greenhouse gas (CO2) in the forestry sector based on the revised 1996 IPCC Guideline as an experiment method by applying national specific factors. As a result of estimation, the greenhouse gas (CO2) of 33,090 tonCO2 for 12 years was more emitted due to construction of a golf course than when it was not constructed, and this value is the same as an average of 2,758 tonCO2/year. In conclusion, the forest damage is unavoidable in construction of a golf course, but it is thought that the construction for preservation of a maximal original form or alternative greens should be achieved to reduce absorption of greenhouse gas (CO2). 본 연구에서는 W시에 소재하고 있는 C 골프장 건설 전 후에 따른 임업부문 온실가스 순흡수량을 산정하고, 장기적인측면 또한 고려하여 비교 연구하였다. 실험방법으로 수정된 1996 IPCC 가이드라인을 기초로 하여 국가적 고유의 계수을적용한 임업부문 온실가스(CO2) 순흡수량 산정식을 사용하였다. 산정결과 골프장 건설로 인하여 12년간 33,090 tonCO2의 온실가스(CO2)가 건설하지 않을 때보다 더 배출되었고, 이 수치는 연평균 2,758 tonCO2와 같다. 결론적으로 골프장건설에 있어서 산림 훼손이 불가피하지만 온실가스(탄소) 순 흡수량 감소를 줄이기 위하여 최대한의 원형보전 건설 또는대체녹지 건설이 이루어져야 할 것으로 사료된다.
