The purpose of this study aims to examine flexural behavior of beam-column specimen retrofitted by CFRP sheet and BRE (Buckling-Restrained Brace) under constant axial and cyclic lateral loads. Three specimens were made with different retrofitting methods: CFRP sheets only and CFRP sheet and BRB systems. Load and displacement capacity was evaluated by comparing load-displacement relations. Lateral load resistant capacities were estimated in terms of the effective stiffness.

Joints of single-layer latticed domes show various flexural behaviors according to their shapes and connecting methods. Ball joints are relatively easy to apply and build while their rigidities are relatively small and have disadvantage in long span. Welded joints have many advantages in rigidity, internal force and long span. However few experimental studies have been performed. In this paper, improved welded joint for the single layer latticed domes was proposed through both analytical and experimental analyses. Length of inserted plates, thickness of inserted plates and hole of sub steel pipes were selected as parameters for experimental comparisons and defining the effects of the selected variables. 단층 래티스 돔에 사용되는 접합부는 그 형태나 접합방법에 따라 다양한 거동 특성을 지닌다. 볼 조인트의 경우, 다루기 쉽고 현장 적용에 유리하지만, 강성과 내력이 약하기 때문에 장스팬의 확보에 있어서 불리하다. 용접 접합부는 볼 조인트에 비해 강성과 내력이 우수하고, 장스팬을 확보할 수 있지만, 용접 접합부에 관한 연구 및 실험은 드문 실정이다. 본 연구에서는 단층 래티스 돔에 적용 가능한 용접 접합부를 제안하고, 이를 기존접합부와의 비교하기 위한 실험을 수행하였다. 또한 제안된 접합부에 대해 삽입 플레이트의 길이, 두께, 여장을 변수로 하여 각각의 변수에 의한 실험체의 거동의 변화를 살펴보았다. 실험을 통한 결과를 토대로 하여 새로운 형태의 용접 접합부를 제안하고자 한다.

풍수해저감종합계획은 지자체에서 수립하는 7가지의 풍수해 유형에 대한 방재종합계획으로서 토석류 위험지구를 사면재해 및 토사재해에 포함하고 있다. 그러나 기 수립된 10개 시ㆍ군의 풍수해저감종합계획 조사 결과 사면재해위험지구 선정과정과 위험지구 지정 후 토석류 발생 가능성을 검토한 사례는 3개 시ㆍ군에 불과하였으며, 토석류 위험지구를 하천이나 하천유역으로 일괄적으로 지정하여 토석류 발생으로 인한 영향지역을 위험지구로 표기하고 지정한 곳은 1개 시ㆍ군에 불과하였다. 따라서 본 연구에서는 산림청 토석류 발생 우려지역 판정표와 국내 토석류 특성을 반영한 토석류 위험지구의 관리구역 설정방안을 마련하였으며, 실제 토석류 피해사례와 토석류 위험지구를 대상으로 적용성 분석을 수행하였다. In comprehensive plan for storm and flood damage reduction is a comprehensive disaster prevention plan formulated by local governments. In the plan, debris flow is included in slope disaster and sediment disaster. However, as a result of analyzing the comprehensive plan for storm and flood damage reduction by the completed 10 local governments, only the 3 local governments examined the possibility of debris flow during slope disaster and sediment disaster dangerous area selection process. In addition, in the case of debris flow the area designated as a dangerous area up to the area where the damage is concerned was only one local government. Therefore, in this study, we studied the method of setting the management area of the debris flow hazard zone reflecting the debris flow risk judgment table (Korea Forest Service) and characteristics of domestic debris flow. Then, we analyzed the applicability of actual debris flow damage cases and debris flow management areas.

Clinical studies were carried out 83 cases of patients with colorectal cancer treated by Hangamdan(抗癌丹) from January 1th 1998 to September 30th 2000. The results were summarized as follows; 1. Distribution of those attached by colorectal cancer, by sex, showed that Male is more then Female, by age, showed that the number of fifties is majority. 2. Distribution of diagnostic stage, in descending order; stage III(53%, top), stage IV(45.8%). 3. The effects of maintenance and improvement in the symptoms with traditional oriental therapy(83.3%) and combined treatment of western and oriental therapy(92.1%) were observed. The effects of the symptoms were as follows: diarrhea(37.3%), abdominal pain (25.3%), general body weakness(22.9%), nausea(20.5%) and etc. in orders. 4. Analysis of hematology attached by colorectal cancer, maintenance and increasing of WBC(89.9%), RBC(74.7%), Hgb(81.1%), Platelet(92.4%) were observed. After taken Hangamdan, the safety of the liver and kidney were as follows; maintenance and decreasing of AST(85.9%), ALT(94.8%), GTP(87.5%), Creatinine(90.9%) were observed. 5. of IL-12 and $IFN-\gammer$ attached by colorectal cancer, increasing of IL-12(53.3%), IFN-{\gammer}(80%)$) were observed. 6. Analysis of QOL attached by colorectal cancer, maintenance and improvement of combined treatment of western and oriental therapy(89.6%), traditional oriental therapy(83.3%) were observed. 7. Analysis of survival in patients with IV stage of colorectal cancer, above 7 months(18.4%), 12 months(65.8%). 8. Analysis of antitumor effects, maintenance of traditional oriental therapy(83.3%) and maintenance and improvement of combined treatment of western and oriental therapy(80.5%) were observed. Analysis of tumor marker attached by colorectal cancer, maintenance and decreasing of CEA(78.8%) were observed. 9. Analysis of curative valuation, maintenance and improvement of traditional oriental therapy(83.3%), combined treatment of western and oriental therapy(72.7%) were observed. From the above results, it is suggested that Hangamdan has significant effects of antitumor and immune activity, also could be usefully applied for colorectal cancer patients by combination with western therapy or alone.

At here, we investigated the historical background, current stage, and concrete therapies of alternatives in cancer therapy. We obtained the conclusion below. 1. Alternative medicine(AM) is a unothodoxial medical physiology, medical practice or intervension that overcome the side effects, faults, limits of coventional medicine. 2. Recentely, as emerging New-age movement, collapse of Decarte's mecanical cosmology, and emphasis on patient rights, the interest of AM is increased, and foreign & domestic use rates of AM are risen. 3. After coventional medicine in cancer therapies that depends on operations, radiations, and chemotherapy is bounded, Alternatives in cancer therapy are rapidly developed, and the majority of users are often considered satisfactory. 4. Alternatives in cancer therapy are classified six boundaries; Diet and Nutrition, Mind-body Technique, Integrated System, Pharmacologic and Biologic treatments, Immuno Enhanced Therapy, Natural and herbal medicine. 5. Looking at contents of Alternatives in cancer therapy, we get to know most of them are similar to the treatment of oriental medicine in holistic method, therapy, philosophy. If we synthesize the alternative medicine's treatment mentioned above and investigate it with oriental medical viewpoint, that may help us approach the conquest of cancer and improve the rate of cure. 6. It is certain that foreign AM will be imported reversely, and we must prepare for rebuilding of Korean traditional AM systemically, investing for activity positively, making national policy for medical system.

Objectives: The purpose of this study was to examine the efficacy of Gamichunggan-san(Jiaweiqinggan-san) on 25 patients who have suffered from alcoholic liver disease. Methods: Gamichunggan-san(Jiaweiqinggan-san) was administered to patients for over 1 months continuously. We checked improvement of clinical symptoms, changes of chemistry hematological test and especially lymphocyte count. Results: The results obtained are summarized as follows. Gamichunggan-san(Jiaweiqinggan-san) has significant effect on the improvement of clinical symptoms. And the improvement ratio of AST, ALT, ${\gamma}$-GTP was 77.8%, 61.5%, 76.2%. In patients with alcohoiic hepatitis, WBC was increased effectively within normal range and those with liver cirrhosis, All of the patients with the inverted ratio of lymphocyte was improved. Conclusions: From the above results, it is suggested that Gamichunggan-san(Jiaweiqinggan-san) have significant effects on recovery of liver malfunction and immune modulation, and also could be recommended as a prescription for alcoholic liver disease.
