Objectives: The purpose of this study is to investigate the mechanism and effect of moxa bucket moxibustion. Objectively, to be used as the quantitative data through the measurement of temperature, and to grasp the thermodynamic characteristics of moxa bucket moxibustion. Methods: We have selected of the moxa bucket moxibustion. We make a comparative study of the thermodynamic characteristics of moxa bucket moxibustion. We examined combustion times, temperatures, temperature gradients in each period during a combustion of moxa bucket moxibustion made by oak wood. Results: 1. We can design the moxa bucket moxibustion that it has 57.6$^{\circ}C$ maximum temperature with 7g weight and 10mm height, if we use more weight of moxa or lower the height of moxa, we can observe relatively elavated maximum temperature. We observe the maximum temperature following the measuring position of moxa bucket and we can see higher temperature at the center of the moxa bucket and lower temperature at the side of the moxa bucket. 2. We can design the moxa bucket moxibustion with 5g moxa and 10mm height that it has 0.121 $^{\circ}C$/sec of maximum temperature gradient, and it has relatively high temperature gradient at lower weight and height condition. 3. We can design the moxa bucket moxibustion with 7g moxa and 15mm height that it has 4,135sec of the longest effective temperature combustion time, if we use more weight of moxa or higher height of moxa, we can observe relatively extended effective temperature combustion time. We observe the longest effective combustion time following the measuring position of moxa bucket. We can see higher temperature at the center of the moxa bucket and lower temperature at the side of the moxa bucket.

It is known that the pattern of combustion temperature can be classified into preheating, heating. retaining and cooling periods. In this experiment. the authors have studied the heating mechanism by the density of moxa material during the heating and retaining periods. The starting point. the point at which it begins to reach the maximum gradient temperature. the ending point of the heating period. and the ending point of the retaining period were measured in order to get effective stmulation by repetition of moxa-combustion. For the experiment. samples of 300mg. 400mg, and 500mg of moxa material were molded into conical molds with each 10mm in diameter and height resulting in the volume of $0.26cm^3$. The following results were obtained: The $300mg/0.26cm^3$ denstiy sample reached al1 points tested faster than the samples of $400mg/0.26cm^3$ and $500mg/0.26cm^3$ It dose not reveal any statistical differences between $400mg/0.26cm^3$ and $500mg/0.26cm^3$ in the ending point. the point at which it begins to reach the maximum gradient temperature of the heating period or the ending point of the reataining period The only difference shown was in the starting point of the heating period. According to the above results. it is concluded that the lower density moxa material reached each point of the the respective period faster than the high density moxa material.

Objective : The purpose of this study is to investigate the mechanism and effect of moxibustion objectively and to be used as the quantitative data for developing the new thermal stimulating treatment by observing the combustion time and temperature of commercial moxaes. Methods : We have selected two types(large-size moxa A(LMA), large-size moxa B (LMB)) among large moxaes used widely in the clinic. We examined combustion times, temperatures in each period during a combustion of moxa. Results : 1. The combustion time in the preheating period was about 30sec in both moxaes on the non-contact heated surface. 2. The combustion time in the heating period was about 345sec in LMA and about 1391 sec in LMB, about 4 times longer in LMB on the non-contact surface. 3. The maximum temperature in the heating period was $44.5^{\circ}C$ in LMA and $45.4^{\circ}C$ in LMB respectively, higher by $0.9^{\circ}C$ in LMB. The average temperature in the heating period was $35.5{\sim}37.6^{\circ}C$ in LMA and $36.0{\sim}39.8^{\circ}C$ in LMB, a little higher in LMB. 4. The combustion time in the retaining period in LMA was 45.4sec and 13% of that in the heating period, and in LMB 594.7sec and 43% of that in the heating period on the non-contact surface. 5. On the point(PH) measured maximum temperature, the average temperature during the retaining period was $44.0^{\circ}C$, $42.9^{\circ}C$ respectively and the temperature at an end of the retaining period was $43.0^{\circ}C$, $40.2^{\circ}C$ respectively. 6. The time at a beginning of the cooling period was about 418 sec from ignition in LMA and 2021sec in LMB, and the temperature at that time was $36.9{\sim}39.1^{\circ}C$ on the non-contact surface. Conclusion : It was thought that not only the figure of moxicombustion device, but also the form and size of moxa had influence on the combustion characteristics deciding the performance of stimulus seriously.

In order to get the basic data for the study of the heat stimulation of burning moxa, the pattern of combustion temperature, which is one of the important factors of thermal characteristics, was measured by density of cone moxa along the time procedure. The following results have been obtained 1) The pattern of combustion temperature by moxa burning was classified into input period which means the infiltration of heat into the area and output period which means the radiation of heat from the area. The input period consists of preheating and heating periods, while the output period consists of heat retaining and cooling periods. 2) The pattern of combustion temperature showed the same type or curve, which was not influenced by the moxa weight. However, Its pattern gradient are varied by density. It is considered that the pattern of combution temperature is primarily influenced by the rate of combustion temperature, gradient temperature and duration of combustion.

Objective : Moxibustion has been proved efficacious for many diseases, but isn't widespread in the clinics due to a danger of skin burning, the smoke produced while burning a moxa combustion and so on. Therefore, another type of moxa that can be resolved these troubles is required. To improve the effect of moxibustion and develop the new thermal stimulating treatment, the performance of commercial moxibustion widely used are studied systematically and found out quantitatively. Methods : We have selected two types (small-size moxa A(sMA), small-size moxa B (sMB)) among small-size moxaes used widely in the clinic. We examined combustion time, various temperatures, temperature gradient in each period during a combustion of moxa. Results : 1. The combustion time in the preheating period appeared somewhat longer in sMA than in sMB. 2, The combustion time in the heating period appeared longer in sMA by 26% than in sMB. 3. The average temperature in the heating period was $37.6{\sim}37.8^{\circ}C\;in\;sMA\;and\;36.2{\sim}36.8^{\circ}C$ in sMB and the maximum temperature measured at a center of contact surface in sMA was $48.6^{\circ}C$, higher by over $2.8^{\circ}C$ than that of sMB moxibustion. 4. The average ascending temperature gradient in the heating period was $0.08{\sim}0.1^{\circ}C/sec$ in both moxaes, and the average ascending temperature gradient of heating period in sMB appeared larger. The maximum ascending temperature gradient appeared higher in sMB, and the time reaching maximum ascending temperature gradient appeared much earlier in sMA than in sMB. 5. The combustion time in the retaining period was around 100 sec in sMA and around 275 sec in sMB. 6. The average temperature in the retaining period was $42.2{\sim}46.0^{\circ}C\;in\;sMA\;and\;39.3{\sim}41.4^{\circ}C/sec$ in sMB. The minimum temperature in the retaining period was over $38.80^{\circ}C$ in sMA but just $34.7^{\circ}C$ in sMB. 7. The average descending temperature gradient in sMA was $-0.050{\sim}0.067^{\circ}C/sec$ and in sMB was $-0.030{\sim}0.037^{\circ}C/sec$ 8. The combustion time in the cooling period appeared longer over two times in sMA than in sMB, and the time which the cooling period (minimum temperature) finished at appeared later in sMB by 55 sec. 9. We classified the combustion process that the measured temperature rose over body heat($37^{\circ}C$) into the effective combustion period. The effective combustion time was 233.3 sec in sMA and 300.4 sec in sMB respectively, and was longer by about 29% in sMB. The average temperature and maximum temperature in the effective combustion time appeared higher in sMA. The time taken until the maximum temperature was reached was 225.1 sec in sMA and 244.5 sec in sMB, faster by about 20 sec in sMA. The maximum ascending temperature gradient during the effective combustion period appeared larger about 1.4 times in sMB, but the time when the maximum ascending temperature gradient happened was faster in sMA. Conclusion : It appears that sMB, compared with sMA, is proper if necessary to apply the long time and weak stimulus, because of the gentle stimulus during the relatively longer time. In contrast, sMA that the symmetrical combustion happened is proper if necessary to apply the short time and strong stimulus.

Objectives : The moxibustion is the method in using the heat stimulation made of attached and burned a moxa or other herbal materials on a healing point or acupuncture point and the chemical stimulation of a resin made from burning them. We need to standardize the characteristics of moxa combustion in order to get more systematic and objective result in operation mechanism and effects and then get more clinical abilities in these fields. Methods : In this study, using of labview system on the moxibustion. 1. we studied relation the size of barley and jujube seed with the moxa cone's peak combustion temperature and then measured and compared the moxa cone's peak combustion temperature by tonification and sedation method. 2. we measured the peak combustion temperature of indirect moxibustion. Results & comclusions : 1. When we measured a direct moxibustion's combustion temperature, the jujube seed sized moxa cone's peak temperature was higher than the barley sized moxa cone's when it burned and the time to peak temperature of the barley sized moxa cone was shorter than the jujube seed sized moxa cone's. 2. When the direct moxibustion was burned by the tonification and sedation method, the sedation method's peak temperature was higher than the tonification method's, the tonification's time to peak temperature was shorter than the sedation method's. 3. When we measured the temperature of the moxa combustion in the kinds of sliced herbal materials, the peak temperature of indirect moxibustion with a ginger when it sliced a 1.3mm size and a 1.5mm size was degreed within $40^{\circ}C$ to $52^{\circ}C$ and the peak temperature of indirect moxibustion with a garlic when it sliced a 1.7mm size was degreed within $46^{\circ}C$ to $62^{\circ}C$.

Objective: The propose of this study is to investigate the characteristics of combustion in indirect moxibustion with garlic. Methods: We observed the characteristics of combustion by the variations of the thickness(3mm, 4mm, 5mm) of a slice for indirect moxibustion with garlic and mass(80mg, 100mg, 120mg) of moxa cone and existence of holes. The temperature of indirect moxibustion for garlic insulation with holes was higher than temperature of indirect moxibustion for garlic insulation without holes. Combustions time in the preheating period is about 1 minute, it varies by the existence of holes, the thickness of a slice for indirect moxibustion with garlic, and the density of moxa cone. Results: Maximum temperature of heating period was $38.7{\sim}46.2^{\circ}C$, combustion time in the heating period was 118~164sec and maximum ascending temperature gradient was $0.102{\sim}0.264^{\circ}C/sec$. Retaining period was shorter than heating period and stimulus of heating retains more, because it is higher than body temperature. By this report, indirect moxibustion with garlic is more effective with holes and the appropriate thickness of a slice for indirect moxibustion with garlic is 3.5~4mm. It is appropriate that the diameter of moxa cone is 8mm and height of that is 10mm. With this condition, effective combustion period is 120sec, maximum temperature is $42{\sim}44^{\circ}C$, maximum ascending temperature gradient is $0.14{\sim}0.16^{\circ}C/sec$. It is necessary to study clinical correlations for more accurate quantitative standard.
