An application of thermal response coefficient method for obtaining thermal load on stud-frame walls in a typical house is presented. A set of stud-frame walls is two-dimensional heat conduction transients with composite structure. The ambient temperature on the right-hand face of the stud-frame walls is a typical day-cycle input and the room temperature on the left-hand face is a constant input. The desired output is thermal load at the left-hand face. The time-dependent ambient temperature is approximated by a continuous, piecewise-linear function each having one hour interval. The conduction problem is spatially discretized as 8 computer modelings by finite elements to obtain thermal response coefficients. The discretization and round-off errors can be neglected in the range of adequate number of nodes. A 60-node discretization is recommended as the optimum model among 8 computer modelings. Several sets of response coefficients of the stud-frame walls are generated by which the rate of heat transfer through the walls or some temperature in the walls can be calculated for different input histories.

For the first time, the theory of ChonKwanChuk(寸關尺) and the examination method of KyungJung(輕重法) of KiGu(氣口) were formed in "NanKyung(難經)". After that, the vicera assignment theory at left and right hands(左右守藏府記屬理論) was established in "MaekKyung(脈經)" After Reserching the theoretical relevance of the two books, theories between the doctors who understood the examination method of ChukBu(尺部診法) of "Somun MaekYoJungMiRon(素問 脈要精微論)" as the examination method of KyungJung(輕重法) and the doctors who understood that method as the method of ChonKwanChuk(寸關尺) were compared and researched. The results were as follows : 1. The posit ion of ChonKwanChuk(寸關尺) of the examination method of ChonKwanChuk(寸關尺法) is explained at 2nd Nan(二難) of "NanKyung" as follows. Chuk(尺) is the position which is 1Chon(1寸, unit) distant from Kwan(關) to the direction of ChukTaek acupuncture point(尺澤穴) and Chon(寸) is the position which is 9Pun(9分, unit) distant from Kwan(關) to the direction of EoJe acupuncture point(魚際穴). And the six vessels(六經) were assined to ChonKwanChuk(寸關尺) on the basis of OHangJaMoSnagSaeng(五行子母相生) at 18th Nan(18難) of NanKyung. After that Yang Hyun-Jo(楊玄操) at Dang Dynasty, Jung Deok-Yong(丁德用), Woo Seo(廬庶) at Song dynasty explaind the examination method of ChonKwanChuk(寸關尺法) of NanKyung as the method of ChonKwanChuk of two hands(兩手寸關尺法) from the viewpoint of "MaekKyung(脈經)". 2. From the viewpoint of MaeKyung, the vicera assignment of the two hand ChonKwanChuk method is as follows. At Chuk of left hand, the Heart and Small intestine are assigned. At Kwan of left hand, the Liver and Gall Bladder are assigned. At Chuk of left hand, the Kidney and Bladder are assigned. At Chuk of right hand, the Lung and Large in testine are assigned. At Kwan of right hand, the Spleen and Stomach are assigned. At Chuk of Right hand, the Vital Gate(命門) and Bladder are assigned. 3. For the first time, HwalSu(滑壽) at Won dynasty said that the paragraph "尺內兩傍${\cdots}{\cdots}$" of "Somun MaekYoJungMiRon" is the first of the examination method of KiGu(氣口診脈法). After that Ma Shi(馬蒔), Jang Gae-Bin(張介賓) of Myung Dynasty, Jang Ji-Chong(張志聰), Seo Dae-Chun(徐大椿) of Chung Dynasty who were influenced by him explained that paragraph as the method of KiGuChonKwanChuk(氣口寸關尺法). 4. Lee Kyu-Jun(李圭晙) explained the paragraph "尺內兩傍${\cdots}{\cdots}$" of "Somun MaekYoJungMiRon" as the method of KyungJung(輕重法) and explained Chok(尺) as the paragraph 'Chuk is low position of Kigu, and it means the depth(氣口之下位也, 言其深也)' and explained that 'the Left and the Right is layers(左右者層數). And he revised that the Jang(臟) must be examined at the inner part and the Bu(府) must be examined at the outer part. By this, he settled the theoratical basis of the method of KyungJung(輕重法). 5. The doctors who used the examination method of ChonKwanChok(寸關尺診法) settled their logical justification of the two hand examination method of ChonKwanChuk(兩手寸關尺診法) by connecting with "Somon MaekYoJungMi-Ron" from the viewpoint of 2nd Nan(難) and 18th Nan(難) of NanKyung and MaekKyung. On the contrary, the doctors who used the examination method of KyungJung(輕重診法) settled their logical justification of the examination method of KyungJung(輕重診法) by connecting with "Somun MaekYoJungMiRon" from the viewpoint of 4th Nan(四難) and 5th Nan(五難).

Objectives : Assuming that the characteristic of meridian system has been similar to this of electric potentials in human body and that measurements of electric potential at well(井穴) and sea(合穴) points in branches of the twelve meridians will be representative of measurements of the twelve meridians, to measure the electric potentials in three patient groups with arrhythmia(AP group), with arrhythmia and cerebral infarction(CI group), and with arrhythmia and hemorrhage(CH group), and then to find out the characteristic of meridian system among 3 groups. Methods : Thirty arrhythmic patients diagnosed by EKG, CT, and deficiency of the heart blood(心血虛症) were divided into 3 groups(AP, CI, CH group). Their electric potential of well and sea points in the meridians were measured 3 times by physiograph. Results : Measurements were analyzed by statistical factor analysis, we obtained that the left side electric potential of well and sea points in branches of the twelves meridians in AP group was divided into two factors, which were the hand meridian without the lung meridian, the foot meridian and the lung meridian, but the right side electric potential was divided into the hand and the foot meridian. In CH group both the left and the right side electric potential was divided into three factors. In CI group the left side electric potential was divided into three factors, but the right side electric potential was divided into two factors. Conclusions : In conclusion, their electrical potentials were different each other among 3 groups. Thus electrical potentials of well and sea points might be the representative meridian to show their characteristics.

This study investigated activation of cerebral cortex in patients with hemiplegia that was caused by neural damage. Key-point control movement therapy of Bobath was performed for 9 weeks in 3 subjects with hemiplegia and fMRI was used to compare and analyze activated degree of cerebral cortex in these subjects. fMRI was conducted using the blood oxygen level-dependent(BOLD) technique at 3.0T MR scanner with a standard head coil. The motor activation task consisted of finger flexion-extension exercise in six cycles(one half-cycles = 8 scans = $3\;sec{\times}\;8\;=\;24\;sec$). Subjects performed this task according to visual stimulus that sign of right hand or left hand twinkled(500ms on, 500ms off). After mapping activation of cerebral motor cortex on hand motor function, below results were obtained. 1. Activation decreased in primary motor area, whereas it increased in supplementary motor area and visual association area(p<.001). 2. Activation was observed in bilateral medial frontal gyrus, middle frontal gyrus of left cerebrum, inferior frontal gyrus, inter-hemispheric, fusiform gyrus of right cerebrum, superior parietal lobule of parietal lobe and precuneus in subjedt 1, parahippocampal gyrus of limbic lobe and cingulate gyrus in subject 2, and inferior frontal gyrus of right frontal lobe, middle frontal gyrus, and inferior parietal lobule of left cerebrum in subject 3 (p<.001). 3. Activation cluster extended in declive of right cellebellum posterior lobe in subject 1, culmen of anterior lobe and declive of posterior lobe in subject 2, and dentate gyrus of anterior lobe, culmen and tuber of posterior lobe in subject 3 (p<.001). In conclusion, these data showed that Key-point control movement therapy of Bobath after stroke affect cerebral cortex activation by increasing efficiency of cortical networks. Therefore mapping of brain neural network activation is useful for plasticity and reorganization of cerebral cortex and cortico-spinal tract of motor recovery mechanisms after stroke.

The meridian, the meridian point and the Acupuncture-Bu-Xie(鍼灸補瀉) of oriental medicine are very important in the Department of Acupuncture and Moxibustion. Until now it has been confused at the practical use, and it showed up many transformation to the ages and many scholars. And then, I made a study of effects on the thermal changes of Sangyang($LI_1$,商陽), Igan($LI_2$,二間), Samgan($LI_3$,三間), Hapkok($LI_4$,合谷), Yanggye($LI_5$,陽谿), Kokchi($LI_{11}$,曲池), Yonghyang($LI_{20}$,迎香) following acupuncture on the Hapkok with the Rotated Acupuncture-Bu-Xie(捻轉補瀉) stimulation. This study researched into clinical statistics for 140 men who are in good health, and they are studying oriental medicine at Woosuk university in Korea. This study was covered a period of 3 months form June, 1999 to August, 1999. The objective was divided into seven groups, those are the control group(CON, N=20), the acupuncture stimulation group with non-rotation on Hapkok of left hand(A-I, N=20), the acupuncture stimulation group with non-rotation on non-meridian point(NA) of left hand(A-II, N=20), the acupuncture stimulation group with Bu-rotation(捻轉補法) on Hapkok of left hand(B-I, N=20), the acupuncture stimulation group with Bu-rotation on non-meridian point(NA) of left hand(B-II, N=20), the acupuncture stimulation group with Xie-rotation(捻轉瀉法) on Hapkok of left hand(C-I, N=20), and the acupuncture stimulation group with Xie-rotation on non-meridian point of left hand(C-II, N=20). The first, I took a picture for 140 men with the Digital infrared thermal image(D.I.T.I.). After 10 minutes, I took a second picture for each group following experimental methods, those were followed acupuncture on the Hapkok and the non-meridian point with the retentive and Rotated Acupuncture-Bu-Xie stimulation. The results are summarized as follows : 1. The thermal changes of the area which is a meridian point in the Large Intestine Meridian of the acupuncture stimulation group on Hapkok different from the control groups with significantly change. 2.The thermal changes of the area which is a meridian point in the Large Intestine Meridian of acupuncture stimulation groups on non-meridian point was not significantly different from the control group. 3. The thermal changes of the area which is a meridian point in the Large Intestine Meridian of the acupuncture stimulation group with Bu-rotation on Hapkok different from the control group with significant increase. 4. The thermal changes of the area which is a meridian point in the Large Intestine Meridian of acupuncture stimulation group with Bu-rotation on non-meridian point was not significantly different from the control group. 5. The thermal changes of the area which is a meridian point in the Large Intestine Meridian of the acupuncture stimulation group with Xie-rotation on Hapkok different from the control group with significant decrease and increase following the decreasing or increasing temperature class, and the increasing temperature class of the acupuncture stimulation group with Xie-rotation on Hapkok significantly different from the acupuncture stimulation group with Bu-rotation on Hapkok. 6. The thermal changes of the area which is a meridian point in the Large Intestine Meridian of acupuncture stimulation group with Xie-rotation on non-meridian point was not significantly different from the control group. As a conclusion, I could think that the acupuncture stimulation with Bu-rotation or Xie-rotation on Hapkok affected the thermal change of the area which is a meridian point in the Large Intestine Meridian. And then I could relate these results with the existence of the meridian and meridian point, and with the Rotated Acupuncture-Bu-Xie theory of oriental medicine.
