Objectives : In order to investigate the effects of So-yangin Biman-bang(here in after referred to BM) on the obese gene and obese inhibitory, C57BL/6 mice were distinctively induced by high fat diet. Methods : C57BL/6 mice were divided into four groups(normal, high fat diet with control, high fat diet with Reductil(here in after referred to RDT), high fat diet with BM extract) and have been fed for 8 weeks. Through observing the process, the weight change of the adipocytes in body and liver, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, glucose, leptin change in the serum, the expression of ${\beta}3AR$ and leptin gene in 3T3-L1 cell and primary adipocyte cell. Results : The following results have been found in this study. 1. Losing weight have significantly been shown. 2. The weight change of the body adipocyte and liver have been decreased but no significance has been found. 3. With close observation on the change of blood, HDL-cholesterol has positively been increased in numbers but the level of glucose, LDL-cholesterol, triglyceride have distinctively been decreased. 4. The manifestation of ${\beta}3AR$ in 3T3-L1 cell and primary adipocyte cell have shown a definite increase in numbers but the manifestation of leptin has shown certain decrease in its amount. Conclusions : As results of this, So-yangin Biman-bang is thought to be effective in metabolic syndrom and lipid metabolism disorder that can possibly be occurred by obesity control and treatment. The clinical research will be needed in order to apply to So-yangin constitution in the future.

Objectives: This study was performed to investigate the anti-obesity effects of Gambi-bang 4 (GBB4) on obesity-induced mice. Methods: C57BL/6 mice were divided into four groups (normal, high fat diet with control, high fat diet with Reductil, high fat diet with GBB4 extract) and fed for 8 weeks. We observed body weight change, the weight change of the adipocytes in body, total cholesterol, LDL-cholesterol, HDL-cholesterol and triglycerides, serum leptin level, expression of ${\beta}3AR$ and leptin genes in 3T3-L1 adipocytes and adipose tissue, and histological changes of adipose tissue and liver cells. Results: 1. Compared with the control group, the GBB4 group was significantly lower in body weight, weight of adipocytes, and amount of glucose. 2. The GBB4 group was significantly lower in the amount of total cholesterol, LDL-cholesterol and triglycerides, and HDL-cholesterol compared with the control. 3. Compared with the control group, the GBB4 group was significantly lower in the amount of serum leptin. 4. The GBB4 group was significantly higher in the revelation of ${\beta}3AR$ and leptin in 3T3-L1 adipocytes and primary adipose cells compared with the control. 5. Compared with the control group, the GBB4 group was smaller in the size of adipocytes in adipose tissue and the adipose vacuoles in liver tissue were decreased. Conclusions: These results suggested that GBB4 has inhibitory effects on obesity. GBB4 might be applied in treatment of obesity, so further studies analyzing its effects are needed.

Now is an automation age. Therefore it is required that machine can do work which was done by men. Artificial Neural Network was developed by the necessity of this purpose. This paper shows a Predictive Control with a Neural Network. The Neural Network learns an Inverted Pendulum in various situations. Then, it has a power to predict the next state after accept the current state. And the Neural Network directs the Bang-Bang Controller to give input to a plant. It seems like that a human expert looks the state of a plant and then controls the plant. It is used a Feedforward Neural Network and shown control state according to the learning. We could get a satisfactory results after complete learning.

대형 구조물에 작용하는 큰 외력은 능동 제어 장치의 제어입력에 포화를 종종 유발한다. 그리고 구조물이 대형화될수록 질량, 강성 등의 파라미터들에 대한 정확한 값을 알기가 어려워지므로, 수학적인 모델과 실제 구조물과의 모델링 오차는 파라미터들에 대한 불확실성으로 제어기의 설계 시에 고려되어야 한다. 그러므로 건축 및 토목 구조물에 대한 능동 진동 제어 방법을 다룰 때 제어기의 안정성을 보장하기 위하여 제어입력의 포화와 계의 파라미터 불확실성을 동시에 고려한 강인 포화 제어기의 설계가 필요하다. 여기에서는 건물의 능동 진동 제어에 연구 및 적용되어진 여러 제어기들 중에서 선형 최적 제어기 LQR, 수정된 뱅뱅 제어기, 포화 슬라이딩 모드 제어기, 강인 포화 제어기의 안정성을 살펴본다. 특히 제안된 강인 포화 제어기의 필요성을 보이기 위하여 LQR, 수정된 뱅뱅 제어기, 포화 슬라이딩 모드 제어기들이 제어입력의 포화나 파라미터 불확실성이 존재하는 경우에 불안정해지는 현상들을 보인다. 2자유도 진동계에 대한 수치 예제와 능동 질량 감쇠기(AMD)를 이용한 2층 구조물에 대한 실험을 통하여 강인 포화 제어기의 강인 안정성을 보인다.

수중에서 로봇으로 사석 고르기 작업을 실시할 경우 로봇 주위의 지형 정보를 실시간으로 제공해야 원격조종이 가능하다. 현 위치로부터 주변지형의 높낮이를 보여줘야 운전자가 작업 계획을 수립하고, 전복과 같은 사고도 예방할 수 있다. 지금까지 지형인식은 멀티 빔 소나에 의해 이뤄졌는데 이는 작업 전후의 품질을 평가하는 용도만 사용되었지 원격조종에서 필요한 실시간 정보로는 사용될 수 없었다. 본 연구는 수중 사석 고르기 작업을 위한 실시간 지형인식 방법을 개발한다. 버킷이 지면을 누를 때 전달되는 힘을 측정해 접촉여부를 판단하고, 실린더의 길이를 읽어 접촉위치를 계산한다. 버킷의 위치제어를 위해 가변 뱅뱅제어 알고리즘을 적용하고 숙련된 굴삭기 운전자의 작업패턴을 프로그램화해 지형인식, 긁기, 밀기, 전진 등의 작업을 자동으로 수행하도록 한다. 개발된 방법은 로봇 몸체로부터 버킷의 거리에 따라 3차원 격자 지형을 상대적으로 보여줌으로써 작업자가 쉽게 지형을 인식하고 지형에 따라 작업계획을 세우도록 한다.

Background : Although chronic non-bacterial prostatitis is increasing, it is hard to treat effectively. In western medicine, antimicrobials drug, ${\alpha}$-adreno-ceptor antagonists, anti-inflammatory drugs, tricyclic antidepressants and anticholinergic agents are used commonly, but chronic prostatitis/chronic pelvic pain syndromes is confusing and frustrating for urologist. IDS(Indongsoyeom-bang) is used in treatment of chronic prostatitis/chronic pelvic pain syndromes. And it is reported that GLS(Gleditsiae spina) and TOF(Toosendan fructus) components of IDS have significant effect on protection of the glandular epithelial cells. Objective : In this study was conducted to investigate the therapeutic effects and action machanism of IDS in the rat model of non-bacterial prostatitis induced by castration and testosterone treatment. Methods : We observed six experimental objects of normal group, control group, testosterone group, and IDS 50 mg/kg, 200mg/kg, 400mg/kg group. Rats were treated with 17 ${\beta}$-estradiol after castration for induction of experimental non-bacterial prostatitis, which is similar to human chronic prostatitis in histophatological profiles. IDS and testosterone were administered as an experimental specimen and a positive control, respectively. The prostates were evaluated by histological parameters including the epithelial score and epithelio-stromal ratio for glandular damage. Also, the prostates were observed by Hematological alterations of WBC, RBC, hemoglobin and platelet. Results : While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation, the rats treated with IDS-50 showed a diminished range of the tissue damage. Epithelial score was improved in IDS than that of the control. The epithelio-stromal ratio was lower in IDS when compared to that of the control. Also, the examination of bloods were not observed hematological change. Conclusion : These finding suggests that IDS may protects the glandular epithelial cells. We concluded that IDS could be a useful remedy agent for treating chronic non-bacterial prostatitis.

Objective : To investigate the effects of Pyeongwi-san-gamibang on atopic dermatitis, this study measured TEWL(transepidermal water loss), observed scratching behaviors and checked levels of Total IgE, IL-4, IFN-${\gamma}$ and conducted skin biopsy on NC/Nga mice with atopic dermatitis. Methods : NC/Nga mice were challenged with DNCB during 5 weeks to develop atopic dermatitis-like skin lesions. The NC/Nga mice with atopic dermatitis were divided into three groups of control group, PW-d, PW-e group. Once a day for 22 days, Pyeongwi-san-GamiBang extract with water was administered for the PW-d group and the extract with 80% ethanol was administered for PW-e group compared with saline solution for control group. During drug administration, sensitization by DNCB had lasted for three times per week. Results : 1. TEWL had no statistical difference among 3 groups. 2. The scratching behaviors had no statistical difference among 3 groups. 3. The levels of Total IgE in PW-d, PW-e group had a statistically significantly higher than that of the control group although difference between the control group and the PW-d, PW-e group were similar. 4. The level of IL-4 had no statistical difference among 3 groups. 5. The level of IFN-${\gamma}$ had no statistical difference among 3 groups. 6. As the observation of toluidine blue stained lesion, both PW-d and PW-e group had lower level of histamine releasement compared with the control group. Conclusion : Result based on these experiments, Pyeongwi-san-GamiBang on atopic dermatitis-like skin inflammation in NC/Nga mice is not effective. But, as the study showed significantly individual differece, we need to repeat these study after supplementing the object number and modified indicator of clinical severity.
