Primary Outcome Measures:
- absolute humidity at both limb of breathing circuit just distal portion of Y-piece [ Time Frame: time point 1-11 ] [ Designated as safety issue: No ]time point 1; base line value (fresh gas flow(FGF); 8L/min) time point 2; 5 mintues(min) after FGF change to predetermined level time point 3; 10 min after FGF change to predetermined level time point 4; 15 min after FGF change to predetermined level time point 5; 30 min after FGF change to predetermined level time point 6; 45 min after FGF change to predetermined level time point 7; 60 min time point 8; 75 min time point 9; 90 min time point 10; 105 min time point 11; 120 min
Secondary Outcome Measures:
- patient body temperature(BT) [ Time Frame: time point 1 -11 ] [ Designated as safety issue: No ]measure BT using esophageal temperature probe each time points are same as primary outcome
- temperature at both limb of breathing circuit just distal portion of Y-piece [ Time Frame: time point 1- 11 ] [ Designated as safety issue: No ]the time points are same as primary outcome

| Experimental: humidity |
Device: Datex Ohmeda excel anesthesia machine
maintain one of following fresh gas flow, 1 or 4 L/min (nitrous oxide:oxygen =1:1) during 2 hour with using Datex Ohmeda excel anesthesia machine after draping complete
Other Name: Excel
Device: Datex Ohmeda Avance anesthesia work-station

Detailed Description:
The fresh gas flow(FGF) is dry and cold in old fashioned anesthesia machine, especially at high folw (above 1 L/min). To the contrary, it has been assumed that the heat and humidity of FGF may be preserved using low FGF (below 1 L/min) during anesthesia or new anesthesia work station. However, it has not been proved yet. We hypothesized that the heat and moisture of FGF may be different in various FGF rate during anesthesia. In addition, it may be different in accordance to anesthesia work station. Therefore, we planed prospective observational study that will demonstrate that the difference of heat and moisture of FGF in different anesthesia work station (Excel; 1st generation anesthesia machine of Datex-Ohmeda Corp., Avance; 2nd generation anesthesia work station of Datex-Ohmeda Corp., Cato; 2nd generation generation anesthesia work station of Drager, Primus; 3rd generation generation anesthesia work station of Drager) and different FGF (0.5, 1, 4 L/min)
