  • Idazoxan, $\alpha$$_2$-adrenergic antagonist, produced antidiuretic action by administration into the vein and diuretic action only in ipsilateral kidney by injection into a renal artery in dog. These studies were performed for investigation of mechanism on the renal action induced by idazoxan. Antiduretic action by idazoxan given into vein and diuretic action only in ipsilateral kidney by idazoxan injected into a renal artery were blocked entirely by renal denervation. Antidiuretic action of idazoxan given into the vein was weakened by UK 14,304, $\alpha$$_2$-adrenergic agonist, pretreated into the vein. Above results suggest that antidiuretic action of idazoxan given into the vein is caused by blocking of $\alpha$$_2$-adrenergic receptor, diuretic action only in ipsilateral kidney of idazoxan injected into a renal artery by blocking of $\alpha$$_2$-adrenergic receptor in the kidney.

  • This study was presented the small action by the budge sonance function. An estimation of budge sonance function was acquired displacements across all condition with a variation of small action. The budge sonance function was to be indicated to express the flow rate of body motion. Their function was suggested an issue of the action condition by budge sonance. This system was proposed a combination of the body motion and small action. The acquired sonance signal was to render the small action of body motion with budge sonance function. The analysis of budge function was generally realized a variation from displacements on the fast body motion. Budge sonance signal of action that vision condition was acquired to a variation of the $Vi-{\beta}_{AVG}$ with $(-4.954){\pm}(-5.42)$ units, that vestibular condition was acquired to a variation for the $Ve-{\beta}_{AVG}$ with $(-2.288){\pm}0.212$ units, that somatosensory condition was acquired to a variation for the $So-{\beta}_{AVG}$ with $(-0.47){\pm}0.511$ units, that CNS condition was acquired to a variation for the $C-{\beta}_{AVG}$ with $(-0.171){\pm}(-0.012)$ units. Budge sonance function was proposed the small action from axial action on body control. We know a body motion response from axial action was not only variation of budge sonance, but also body motion of fast body motion.

  • Action learning motivates students to solve open-ended problems by 'developing skills through doing'. This paper reviews the concept of action learning and discusses the adoption of action learning approach to teach operations management at universities. It presents the design and delivery of an action-learning course at City University of Hong Kong. The course incorporates classroom lectures, tutorials and an action-learning workshop. The experience gained proves that action learning facilitates student participation and teamwork and provides a venue of accelerating learning where enables students to handle dynamic problem situations more effectively. The paper concludes that adopting action-learning approach can help lecturers to enhance quality teaching in operations management courses, and provide an alternate means of effective paradigm other than traditional classroom teaching and/or computer-based training at universities.

  • Renal action of domperidone known as dopamine receptor blocker and effect of domperidone on renal function of dopamine were investigated in dog. Domperidone, when administered into vein, produced diuretic action by the improvement of renal hemodynamic state, when given into a renal artery, elicited diuretic action accompanied with natriuresis in only experimental kidney, whereas domperidone given into carotid artery exhibited antidiuretic action by the decrease of Na$^{+}$ excretion in urine. Diuretic action of dopamine was not influenced by domperidone given into vein or into a renal artery, was blocked by domperidone given into carotid artery. Above results suggest that domperidone produced both peripheral diuretic and central antidiuretic action, and domperidone do not block diuretic action by renal hemodynamic improvement of dopamine in kidney.

  • Highly informative admissible heuristics can help to conduct more efficient search for optimal solutions. However, in general, more informative ones of heuristics from planning problems requires lots of computational effort. To address this problem, we propose an Delete Relaxation based Action Costs-based Planning Graph(ACPG) and Action Costs-based Heuristics for solving optimal planning problems more efficiently. The ACPG is an extended one to be applied to can find action costs between subgoal & goal conditions from the Relaxed Planning Graph(RPG) which is a common means to get heuristics for solving the planning problems, Action Costs-based Heuristics utilizing ACPG can find action costs difference between subgoal & goal conditions in an effective way, and then consider them to estimate the goal distance. In this paper, we present the heuristics algorithm to compute Action Costs-based Heuristics, and then explain experimental analysis to investigate the efficiency and the accuracy of the Action Costs-based Heuristics.

  • Purpose: The purpose of this study was to investigate the improve on brain activity during action observation training for cerebral palsy of diplegia. Design: Randomized controlled trial. Methods: 18 subjects were divide into two groups: action observation training group and a control group. Action observation group practiced repeatedly the action with their motor skill and control group practiced conventional physical therapy. The subjects participated in eighteen 30-min sessions, 3 day a week, for 6week. To confirm the effects on brain activity were evaluated. Results: The results show that the Mu-rhythm was statistically significant increase on the C3 of the action observation training group (p<0.05). Conclusion: The action observation training improves brain activity of a cerebral palsy with diplegia. These results suggest that the action observation training is feasible and beneficial for improving brain activation for the cerebral palsy with diplegia. In the future, I think we need to be actively utilized to the action observation training program in the clinical with the neuromuscular development treatment. And the study on the various the action observation training program that can improve the function of the children with cerebral palsy is thought necessary.

  • This study was attempted to investigate the pharmacological action, especially depressor action of Phellodendri cortex and to elucidate the mechanism of its action, making use of Phellodendri cortex methanol extract (PCME) because its hypotensive action is not clear. Influence of PCME on the blood pressure of the rabbits and cats were observed in this study. PCME, when given intravenously in the rabbits and cats, elicited the hypotensive action, but intraventricular PCME in the rabbits did not show depressor action. Accumulation and tachyphylaxis by PCME administered into the ear-vein of the rabbits were not shown. Depressor effect of PCME in the rabbits was attenuated significantly by pretreatment with phentolamine, guanethidine, chorisondamine and atropine, but not by propranolol, diphenhydramine, cyproheptadine and vagotomization. The pressor activity of angiotensin was unimpaired after injection of maximal hypotensive doses (100mg/kg) of PCME, but the pressor activity of norepinephrine and carotid occlusion was abolished markedly. In addition, PCME given into jugular vein of the cats weakened norepinephrine pressor responses and caused the reversal of epinephrine pressor responses. These results suggest that the hypotensive action of PCME may be due to dual mechanisms by interference with peripheral sympathetic function, alpha adrenoceptor blocking action, and peripheral parasympathomimetics action, muscarinic action.

  • In dogs, renal denervation did not affect the diuretic action accompanied with renal hemodynamic chanties and inhibition of electrolytes reabsorption rates in renal tubules by methoxyverapamil infused into the vein or into a renal artery, while renal denervation blocked the antidiuretic action due to the decreased free water and osmolar clearances along with the reduced sodium amounts excreted in urine by methoxyverpamil infused into the carotid artery. These experimental results suggest that methoxyverapamil may cause diuresis by direct action in kidney but the antidiuretic action through central function mediated by renal nerves.
