  • 이 연구는 여가시간 신체활동 의도와 운동행동 간의 관계에서의 틈(gap)을 극복하고 이 관계를 잇는 매개 변인들의 역할을 검증하고, 기존의 계획행동이론의 확장을 도모하는데 목적을 두었다. 이에 여가시간 신체활동에 대한 의도와 운동행동 간의 관계에서 실천계획-1)극복계획과 2)실행계획-의 매개효과를 검증하였다. 연구의 목적을 달성하기 위하여 편의표집법을 활용하여 강원도 내 위치한 세 곳의 대학에서 교양체육에 참여하고 있는 대학생 253명(남학생=118; 여학생=105)을 대상으로 설문조사를 하였다. 수집된 자료는 SPSS와 Amos프로그램을 활용하여 분석되었으며, 기술통계, 신뢰도, 상관분석, 그리고 구조 관계를 검증하기 위해 구조방정식 모형을 적용하여 의도, 극복계획 및 실행계획, 그리고 여가시간 신체활동 및 운동 간의 관계를 검증하였다. 특히, 의도와 행동 간의 관계에서 극복계획과 실행계획의 매개효과를 검증하기 매개 분석을 실시하였다. 그 결과, 신체활동 의도는 실행계획과 운동행동에 직접적으로 영향을 미쳤으며, 실행계획은 의도에 비해 실제 운동행동을 더욱더 잘 예측하는 것으로 나타났다. 따라서 매개변인인 극복계획과 실행계획은 신체활동에 대한 참여 의도가 실제 운동행동에 미치는 영향에서 부분적으로 모두 매개역할을 하는 것으로 나타났다. 이 연구를 통해 나타난 결과를 종합해 보면, 극복계획과 실행계획의 개념화와 모형검증은 의도-행동의 틈을 극복하고 실제 현장에서 실용적으로 활용될 수 있다는 사실을 알 수 있었다.

  • The cardiac activation process using three dimensional ventricular model is simulated.To study this theme, we constructed a cardiac ventricular model and simulated the cardiac activation process using the action potential duration and the activation time. The cardiac ventricular model is generated by the logical combination of the elliptic equations. The action potential duration could be obtained from the fact that it is linearly distributed between model cells. The cardiac activation process was simulated by the law of "all-or-none" Based on the activation time and the action potential do-ration the cardiac potential at the arbitrary time after the activation of the model cell was computed. To test the validity of model, the comparison of the results of model simulation with the physiological data was performed. In conclusion, this model shows the simular results which is comparable to the real conduction of the cardiac excitation.xcitation.

  • Verapamil, $Ca^{2+}$-channel blocker, when given into vein or into carotid artery, produced the decrease of urine flow accompanied with the decreased amounts of Na$^{+}$ and $K^{+}$ excreted in urine ($E_{Na}, E_{K}$) and with the decreased clearances of free water (C$_{H_2O}$) and osmolar substance (C$_{osm}$), and then increased reabsorption of Na$^{+}$ and $K^{+}$ in renal tubules (R$_{Na}$, R$_{N}$), glomeruler filtration rate (GFR) and renal plasma flow (RPF) were inhibited when verapamil was given into carotid artery, but were only tendency of reduction when given intravenously. Verapamil, when infused into a renal artery, exhibited diuresis accompanied with the increased GER, RPF, E$_{Na}$ and E$_{K}$, with the decreased filtration fraction (FF) in only infused kidney. At the same time, $C_{H_2O}$ was not changed, R$_{Na}$ and R$_{K}$ were reduced. Antidiuretic action by verapamil administered into vein or into carotid artery in normal kidney was reversed to diuretic action in denervated kidney. At this time, parameters of renal function exhibited the opposite phenomena compared to that elicited by verapamil in normal kidney, wherease renal denervation did not influence the action of verapamil infused into a renal artery. Above results suggest that verapamil produce both antidiuresis through nervous system centrally, not endogenous substances and diuresis by direct action in the kidney. Diurectic action are caused by hemodynamic improvement through dilatioon of vas efferense and by greatly inhibited reabsorption of electrolytes in distal tubules.

  • Purpose : This study was conducted to evaluate the effects of an task oriented training program combined with action-observation on balance and gait ability of patients with chronic stroke. Method : The subjects of this study were 30 patients with hemiplegia who agreed to participate and were picked up. Participants were randomly divided into equal groups; namely, an experimental group that underwent task oriented training combined with action-observation for at least 30 minutes/day for 6 weeks and a control group that underwent general task-oriented training. Patients' balance was assessed using the Sway Length, Sway Area and Limit of Stability test. In addition, gait ability was assessed using the 10 Meter Walking Test to measure the taken to walk 10 meters. Gait time and speed taken to walk 10 meters were used to examine gait ability. Results : There were significant improvements in the subscales of the balance and gait ability test of those who participated in the action-observational training program, while the control group showed only significant changes in the evaluation items of the sway length in eyes opened condition and gait time. Conclusion : Therefore, Action-observational training program effectively improved the balance and gait ability in patients with stroke.

  • In this study, I examined the concept of action learning, its characteristics, operation method, and action learning cases in domestic and foreign countries. Also, I studied the possibility of using action learning in teaching healthy family specialist education. I researched the wellbeing action learning held from June 10 to June 20, 2007, with 20 participants. I conducted interviews and wrote a paper about how much action learning subjects were helped in their improving task-handling ability, its merits and drawbacks, and suggestions the subjects had about their participation in. The results were as shown below. First, the Catholic Welfare Department of Baekseok Uuniversity developed and operated action learning subjects to improve task-handling abilities in NURY business. Second, the action team valuated its subjects that everyone had fear and burden about action learning, but as time goes by, their confidence and adaptation ability have been improved. Also, organization staff and coaches answered that it was helpful to their self-development and improve capacity.

  • In order to investigate the effects of Kamikwakjeongtang by using the experimental animals. the action on gastrointestinal smooth muscles. the action of gastric juice secretion, the action of antiulcer. the transport ability of intestinal contents. the action of anticatharsis and the actions on the central nervous system were studied. The results were as follow: 1. Spontaneous motility of the isolated ileum of mice was suppressed and antiacetylcho-line chloride action was recognized. 2. Anti-action on barium chloride of fundus-strip of white rat was recognized. 3. Supression effects on gastric juice secretion. free acidity was recognized. 4. Preventive effect on the ulcer induced by pylorus-ligated was recognized. 5. Supression effects of large intestinal transport ability was recognized. 6. Anti-carthartic action was shown but was not recognized. 7. Analgesic effect by the acetic-acid method and prolonged effect of the total sleep time by pentobarbital-Na were recognized. According to the above results, effects based on oriental medical reference were consistent with the actual experimental effects.

  • Purpose: To develop a risk metric for failure cause that can help determine the action priority of each failure cause in FMEA considering time sequence of cause- failure- detection. Methods: Assuming a quadratic loss function the unfulfilled mission period, a risk metric is obtained by deriving the failure time distribution. Results: The proposed risk metric has some reasonable properties for evaluating risk accompanied with a failure cause. Conclusion: The study may be applied to determining action priorities among all the failure causes in the FMEA sheet, requiring further studies for general situation of failure process.
