Cheiro-oral syndrome is characterized by a partial sensory disturbance in one hand and the ipsilateral oral comer. Its lesion is on the sensory track, and it is comparatively small. Most studies are case studies. These studies reported less than 10 cases. We studied two cases. In one, we observed intracranial hemorrhage involving left thalamus, posterior limb of internal capsule about 5cc in brain computed tomographic scan. The case was shown paresthesia of the right hand and ipsilateral comer of the mouth. The patient also complained about disturbing dysstereognosis and disorder of graphaesthesia. In the other case, we observed nodular calcification at the left basal ganglia external capsule in brain computed tomographic scan. The patient also complained about dysesthesia of the right thumb and index finger, fatigue and verbal disturbance. These cases appeared to be typical strokes in the acute phase, but after acute phase, they had dysethesia in the hand and periord for three months.

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).

This study was undertaken to evaluate the efficacies for myocardial protective effect of retrograde right atrial perfusion [RRAP] of cardioplegia compared with antegrade aortic root perfusion [AARP]. Myocardial distribution of perfusate [using methylene blue] with RRAP was less poor to AARP. Myocardial protective effect was estimated with myocardial temperature and electron microscopy. Cooling protection of right ventricle with RRAP was similar to AARP. On the other hand, cooling protection of left ventricle with RRAP was slight poor to AARP. The electron microscopic ischemic change of right and left ventricle with RRAP was similar to AARP. RRAP was thought to be a good alternative method to perfuse cardioplegia and protect both ventricle.

Purpose: Human brain was lateralized to dominant or non-dominant hemisphere, and could be reorganized by the processing of the motor learning. We reported four cases which showed the changes of the cortical activation patterns resulting from two weeks of training with the serial reaction time task. Methods: Four right-handed healthy subjects were recruited, who was equally divided to two training conditions (right hand training or left hand training). They were assigned to train the serial reaction time task for two weeks, which should press the corresponding four colored buttons as fast as accurately as possible when visual stimulus was presented. Before and after two weeks of training, reaction time and function magnetic resonance image (fMRI) was acquired during the performance of the same serial reaction time task as the training. Results: The reaction time was significantly decreased in all of subjects after training. Our fMRI result showed that widespread bilateral activation at the pre scanning was shifted toward the focused activation on the contralateral hemisphere with progressive motor learning. However, the bilateral activation was still remained during the performance of the non-dominant hand. Conclusion: These findings showed that the repetitive practice of the serial reaction time task led to increase the movement speed and accuracy, as described by motor learning. Such motor learning induced to change the cortical activation pattern. And, the changed pattern of the cortical activation resulting from motor learning was different each other in accordance with the hand dominance.

In this paper, we proposed the straight line determination method and the algorithm for 8 directions determination of straight line using the coordinate information and the property of trigonometric function. We conduct an experiment that is 8 hand gestures are carried out 100 times each, a total of 800 times. And the accuracy for the 8 derection determination algorithm is showed the diagonal direction to the left upper side shows the highest accuracy as 92%, and the direction to the left side, the diagonal direction to the right upper side and the diagonal direction to the right bottom side show the lowest accuracy as 82%. This method with coordinate information through image processing than the existing recognizer and the recognition through learning process is possible using a hand gesture recognition gesture.

Background: It has been proposed that proprioceptive input can modulate neural excitability in both primary motor cortices (M1) simultaneously, although direct evidence for this is still lacking. Previous studies showed that proprioceptive accuracy of one hand is reduced after the application of one-Hz repetitive transcranial magnetic stimulation (rTMS) for 15 minutes over the contralateral somatosensory cortex. The aim of this study was to investigate the effect of rTMS-induced central proprioceptive deafferentation to excitability of both M1 as reflected in ipsilateral and contralateral motor evoked potentials (MEP). Methods: MEPs of both abductor pollicis bravis (APB) muscles were recorded using single-pulse TMS over right M1 in seven healthy subjects. Immediately after one-Hz rTMS was applied for 15 minutes over the right somatosensory cortex, the MEP measurement was repeated. The proprioceptive function of the left thumb was assessed, before and after rTMS, using a position-matching task. Results: There was an increase in ipsilateral MEP after the rTMS: whereas no MEPs were recorded on the ipsilateral hand before the rTMS, MEPs were recorded in both ipsilateral and contralateral hand in three of seven subjects. At the same time, the mean log amplitude was reduced and the mean latency was prolonged in the contralateral MEP. Conclusions: rTMS-induced central proprioceptive deafferentation reduces the MEP generation in the contralateral hand, and fascilitates that in the ipsilateral hand. A further study with a larger sample seems warranted to confirm this finding and to elucidate the neurophysiology underlying it.

Through various media, damage of both smoking and second-hand smoking has been recognized, and brought global scale of interest in antismoking. In Korea, government has tightened regulations of smoking in non-smoking zone since December, 1980, and after National Health Promotion Act in 1995, non-smoking zone has been gradually expanded. On the other hand, there were law suits to find those regulation towards smokers are either unconstitutional or not for 4 times. In this current state, people need smoking area to prevent second-hand smoking and to consider smokers in multi-unit dwelling. Main purpose of this research is to plan smoking spaces based on various typology of multi-dwelling plan for protection of both smokers and non-smokers' right. The research group collected and analyzed the smoking behaviors in various multi-unit dwelling types such as flat type, tower type, hybrid type and others. Based on those data, the group found three phenomena. First, there are internal regulations in multi-unit dwelling to make non-smoking zone based on National Health Promotion Act and resident representative meeting decision. Second, main smoking activities are occurring at major traffic line and entrances. Third, smoking inside of multi-unit dwelling complex causes second-hand smoking to residents live in $1^{st}$ floor and when they enter. Therefore, one can achieve both smokers' and non-smokers' protection of right by creating a designated smoking space near main entrances of multi-unit dwelling complex to consider smokers' and prevents second-hand smoking by using shaft space, which is in core space, to ventilate tobacco smoke through roof.

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.

Background: The aim of this study was to analyze the interaction between neck and/or wrist pain and hand grip strength (HGS) and to investigate factors (age, sex, neck disorders, and carpal tunnel syndrome) influencing the HGS of industrial quality proofing workers (N = 145). Methods: Standardized questionnaires [Neck Disability Index (NDI), Boston Carpal Tunnel Questionnaire] were used to evaluate existing neck and/or wrist pain. HGS measurements were performed in different wrist positions. Results: Significant differences between participants with and without neck pain were found in different wrist positions, in neutral wrist position right [without neck pain (n = 48) 46.34 (43.39 - 49.30); with neck pain (n = 97) 38.46 (36.20 - 40.72), F_(1,144) = 16.82, p < 0.001, ŋ_p² = 0.11] and left [without neck pain 44.06 (41.19 - 46.94); with neck pain 37.36 (35.13 - 39.58), F_(1,144) = 12.70, p < 0.001, ŋ_p² = 0.08]. A significant difference between participants with and without wrist pain was found for neutral wrist position right [without wrist pain (n = 105) 42.53 (40.37 - 44.70); with wrist pain (n = 40) 37.24 (33.56 - 40.91), F_(1,144) = 6.41, p = 0.01, ŋ_p² = 0.04]. Regression analysis showed significant results especially for steps two (age and weight, NDI) and three (age and weight, NDI, Boston Carpal Tunnel Questionnaire) for neutral position right (R² = 0.355, R² = 0.357, respectively). Conclusion: Neck pain has an impact on HGS but should be evaluated in consideration of age and sex.

Unexplained pain and weakness, i.e., without obvious predisposing factors, are often encountered by physiatrists and efforts should be made to determine the cause. A 63-year-old male presented with radiating pain in his right arm and mild weakness of the right hand. An electrodiagnostic examination revealed distal symmetric sensory polyneuropathy in the upper and lower extremities, and denervation potentials in the forearm muscles, which were inconsistent with the cervical spine MRI images and symptoms. A predisposing undiscovered disease was revealed, i.e., squamous cell carcinoma in the lung; brain metastasis affecting the left primary motor cortex was also detected. Therefore, we concluded that the pain and weakness were related to paraneoplastic syndrome and brain metastases of the hand knob. The observed denervation potentials were characterized as trans-synaptic changes in the brain metastasis. This case highlights the importance of unexplainable focal pain and weakness in the increasing prevalence of cancer.
