Active sampler has been widely used to measure nicotine concentration in air. The experiments were conducted to compare the active sampler method with diffusive sampler in exposure chamber and smoking areas, respectively. The result of these tests that indicated that passive sampler can be used instead of active sampler in ETS, because coefficient of determination was 0.9292 between active and passive sampling in smoking area

우리나라의 경우 RPS는 신재생전력 보급확대라는 에너지 정책의 일환으로 시작되었으며 현재까지 환경정책의 일환으로 고려되지 않고 있다. 이와 같이 에너지정책만을 고려한 RPS가 시행되고 있는상황에서 ETS가 도입되면 의무대상자인 발전사업자들은 이중규제를 받게 된다. 중복 규제로 인해 발전사업자들은 비용 부담이 가중될 것으로 예상됨으로 RPS와 ETS간 연계를 통해 부담을 완화시킬 수 있는 정책옵션이 필요하다. 본 논문에서는 양 제도간 효과적인 연계방안을 제시하고 개발된 모형을 통해 그 효과에 대해 분석하고자 한다.

The purpose of this study was to analyze the climatic water balance of the Korean peninsula using meteorological data and the evapotranspiration (ET) derived from NOAA/AVHRR. Quantifying water balance components is important to understand the basic hydrology. In this study, a simple method to estimate the ET was proposed based on a regression approach between NDVI and Morton's actual ET using NOAA/AVHRR data. The Morton's actual ET for land surface conditions was evaluated using a daily meteorological data from 77 weather stations, and the monthly averaged Morton's ETs for each land cover was compared with the monthly NDVIs during the year 2001. According to the climatic water balance analysis, water deficit and surplus distributed maps were created from spatial rainfall, soil moisture, and actual and potential ETs map. The results clearly showed that the temporal and spatial characteristics of dryness and wetness may be detected and mapped based on the wetness index.

Adolescents exposed chronically to tobaccotobacco smoke have been found to have reduced pulmonary function as well as an increased risk of lung cancer and a serious heart disease. Consequently, reducing exposure to tobacco smoke is an important public health goal. This study was conducted to develope the exact evaluation method of student smoker or heavy exposure from ETS, and the change on smoking behavior and attitude after a stop-smoking program. From the study, we concluded that the cotinine concentrations in saliva from students indicate exactly whether they are smoker or not. Also, it was found that the more and exact informations from both the cotinine analysis and the questionnaire were obtained than from only the questionnaires. The non-smokers had more positive effects on the changes of cog-nitions, behaviors and attitude about passive-smoking after a stop-smoking program than the smokers. The results of this study show that through both the accurate determination of cotinine in saliva and the questionnaires, the smoking status and the tobacco education effectiveness can be predicted.

The purpose of this study is to see the effect of microbial population and dynamics of the indigeonous microorganisms on hydrocarbon contaminated areas. The microbial structures and activities to determine the microbial capabilities of the contaminated sites are very important for the remedial action technology selection. Throughout microbial studies on different conditions by ETS(Electron Transport System) and microbial activity analysis, it was found that aeration and water contents are the most important factors in this site remediation. According to test results, Burkholderia spp. was dominant species, and acclimation is also an important factor for the accerelated biodegradation.

The introduction of aviation into the EU-ETS has faced significant opposition from many ICAO member States. Accordingly a global solution through ICAO is in progress. This paper traces the progress of works done by the HGCC in the area of global aviation aspiration goals aiming for the submission to the 38th Session of the ICAO Assembly. Furthermore, devices for calculating the carbon dioxide emissions from flights have been developed by several agencies including international organizations, governments, airlines and nongovernmental organizations. These carbon calculators, however, introduce too many assumptions to simplify the calculation process. This study assesses carbon calculators for aviation emissions and suggests a modified calculation methodology using the pre-existing computer reservation system for better accuracy.
