Objective : In order to study effects of decreasement of blood pressure on hypertension patients by moxibustion a clinical study was performed. Methods : Moxibustion at Quchi(LI11), Guanyan(CV4) 10 times on 25 hyper tension patients who were treated via opd on Dong-Eui Oriental Medical Hospital. Results : 1. After 10 times moxibustion at Quchi(LI11), Guanyan(CV4),the systolic blood pressure were decreased 16.5% degree. 2. After 10 times moxibustion at Quchi(LI11), Guanyan(CV4),the diastolic blood pressure were decresed 26.6% degree. 3. Subjective symptoms(i.e. headache, dizziness, heat in the upper part of the body, dyspnea etc) were decresed after 10 times moxibustion at Quchi(LI11), Guanyan(CV4). Conclusion : Continous Moxibustion at Quchi(LI11), Guanyan(CV4) implies decreasement of blood pressure and improvement of subjective symptoms.

Analysis of actuating forces and joint reaction forces are essential to determine the capacity of actuators, to control the system and to design the components. This paper presents an algorithm tha t calculates actuating forces(or torques) depending on the various driving types to produce a given system motion. The joint reaction forces(or torques) of multibody systems with closed-loops are analyzed in the Cartesian coordinate space using the inverse velocity transformation technique. Two numerical examples were carried out to verify the algorithm proposed.

By process of treatment for a case which diagnosed as HNP of left posterolateral aspect of L4/5 disc and treated from the 10th, May 2001 to the 23rd, Jun 2001, the results are as follows. Method & Results : This patient was medicated Hwallaktang-gami, taken acupuncture, phototherapy, TENS, electric acupuncture, exercises, Mori Cortex-bee venom acupuncture. As a result, the patient's clinical symptom were improved but a computed tomagraphy confirmed L4/5 and L5/S1 HNP was not changed as seen on repeated CT scanning. Conclusion : These results suggest that among conservative therapies the oriental medical treatments including Mori Cortex-bee venom acupuncture improve clinical symptom effectively. But in this case, the structure of herniated disc was not changed.

본 연구는 생산공정운영시 발생하는 담당자의 의사결정 지원을 위한 학습형 공정 의사결정 시스템 구축방법에 대한 것이다. 먼저 추출 및 누적된 각 공정 별 이력 데이터에서, 주요한 주요자원(Critical Resource)을 단계적 회귀법에 따라 선정한다. 선정된 주요자원을 독립변수로 취급하여 담당자의 의사결정 대상이 되는 공정운영 성과를 종속변수로 하는 회귀모형을 산출하고, 해당 주요자원으로 구성된 시뮬레이션 모형을 설계한다. 메타휴리스틱 방법을 통하여 의사결정 시점의 생산계획 및 목적에 대한 시뮬레이션 분석을 실행하고, 복수 대안 및 가능해(기대성과)를 산출한다. 각각의 대안에서 주요자원 별 회귀모형을 구성하는 분석 값을 회귀식에 대입하고, 여기에서 얻어지는 값과 시뮬레이션 분석에 의해 산출된 가능해 간의 비교를 통하여 그 차이가 가장 작은 대안을 최적대안으로 선정하고 실제 공정운영 의사결정에 반영하여 생산을 실시한다. 이때 발생하는 공정 이력 데이터들은 이후 의사결정을 위한 회귀모형에 피드백 된다. This study proposes adaptive decision making method having feed-back structure of regression and simulation models to support the quick decision making of production managers by managing and integrating the mutual relationship among historical data. For that, from historical data that have extracted and accumulated from each process, we first selected major constraint resources that are used as independent variables in regression model. The regression model is designed by using the dependent variables (objectives) that defined above by managers and independent variables selected in previous step and simulation model that are composed of constraint resources is designed. In process of simulation run, we obtain the multiple feasible solutions (alternatives) by using meta-heuristic method. Each solution is substituted by regression equation and we found the optimal solution that is minimum of difference between values obtained by regression model and simulation results. The optimal solution is delivered and incorporated to production site and current operation results from production site is used to generate new regression model after that time.

Fe-TiC composite powders were fabricated by planetary ball mill processing. Two kinds of powder mixtures were prepared from the starting materials of (a) (Fe, TiC) powders and (b) (Fe, $TiH_2$, Carbon) powders, respectively. Milling speed (300, 500 and 700 rpm) and time (1, 2, and 3 h) were varied. For (Fe, $TiH_2$, Carbon) powders, an in situ reaction synthesis of TiC after the planetary ball mill processing was added to obtain a homogeneous distribution of ultrafine TiC particulates in Fe matrix. Powder characteristics such as particle size, size distribution, shape, and mixing homogeneity were investigated.
