Postbronchodilator FEV1 = 2.75 L
FVC= 4.5 L
1) FEV1/FVC ratio
FEV1/FVC=2.98/4.5=~0.66 로 약 66%
>> 이 값이 75%이하이므로 Obstruction
2) FEV1%
(post-bronchodilator FEV1기준)
FEV1 %계산시 2.75/4.02=0.684로 약 68%
따라서 50%< FEV1<80% 이므로

predict the amount of LFG that can be produced from wastes in landfill. IPCC Reference Method is one of the methods to estimate methane production in landfill as time series by its 1st order decay model, and it requires to apply methane potential of wastes as an important prarameter.
In this study, BMP(Biochemical methane potential) test was performed to estimate methane potential of various was
of 10th of nation in terms of coffee consumption. This is a result of 10% plus high growth rate since 2000. Brewed coffee market is growing up according to spread of famous coffee shop, small scale foundation and increase of self-consumption. 110 thousand ton of coffee was imported in last year and it has value of $420 million. We can predict every adult drinks approximately 312 cups of coffee. C
of these factors are expressed as housing’s characteristic. Housing is a place where not only people live and do house affair but also reflect modern society and culture phenomenon. Also it can be understood by consciousness of housing from past to present. For these reasons, housing can’t be simply understood as physical form. So it can be fully understood by communicating a value system suc
