Objectives : The discussion of enlargement of Korean Medical insurance has been existed since 1987. But it had less effects. For better discussion, we compared insured herbal extracts and clinical prescriptions. Methods : The database of insured herbal extracts and clinical prescriptions bas set up to compare the ratios of herbal weight and analyze indications of insured herbal extracts and diagnosis and chief complain of clinical prescriptions. Results & Conclusions : The most frequent insured herbal extract is Bojungiki-tang. Analysis about indications of insured herbal extracts and diagnosis and chief complain of clinical prescriptions is that Bojungiki-tang is used frequently for gastrointestinal diseases, pulmonary diseases, and not for diseases. Bojungikgi-tang is also used for muscloskeletal dieases, hemorrhage, and ischemia.

물리 화학적인 특성이 다른 다공성 고분자 마이크로겔에 대한 bovine serum albumin (BSA-protein) 단백질의 흡착평형 특성을 연구하였다. 수용액 속에서 고분자와 단백질사이의 소수성 상호작용에 의하여 폴리부틸메타크릴레이트 (PBMA) 마이크로겔이 폴리비닐피리딘 (PVP)과 폴리아크릴로니트릴 (PAN) 마이크로겔보다 높은 흡착특성을 나타내었으며, PBMA 마이크로겔이 PVP와 PAN 마이크로겔보다 비가역적으로 흡착평형 특성을 나타내었다. 그러므로 고분자 마이크로겔의 물리적인 특성과 단백질-고분자 마이크로겔 사이의 정전기적 인력보다는 소수성 상호작용이 단백질의 흡착특성에 중요한 역할을 하고 있음을 알 수 있다. 또한 PBMA, PVP 및 PAN 마이크로겔 모두 Freundlich 흡착 등온식보다는 Langmuir 흡착 등온식에 잘 적용되었다.

The purpose of this study was to review the literatures of experimental tracheal reconstruction. Although there have been significant advancements in the surgical treatment of the long circumferential tracheal injuries, there still has been a difficult problem with high morbidity and mortality. The method for tracheal reconstruction after circumferential resection is preferred end-to-end anastomosis for defects up to 6 cm in length, but larger tracheal defects require the use of tracheal allograft, various artificial prosthesis or autogenous organs. The tracheal allotransplantation has been widely used as there was significantly improved the method of surgical technique, preservation and immunosuppression. But it has been limited by a number of factors such as few donor, limited use of immunosuppressant, delayed revascularization and re-epitheliazation. Experimental studies on the tracheal prosthesis have a long history and they tried to use silicone, polytetrafluoroethylene, polypropylene mesh, Dacron, Marlex mesh, external or internal stents. Other experimental studies were reported the use of autogenous tissues that were cartilage. jejunum, aorta, skin, muscle, periostium or esophagus. But a great variety of these protheses have been resulted unsatisfactory in a significant Proportion of cases. Alternatively, the tissue-engineering technique has showed a new approach to reconstruct trachea and much progress in tissue-engineering bas been made recently. In conclusion, although the tracheal allotransplantation and the use of prosthesis and allograft have been reported a lot of limitation to overcome, we could sooner expect good result of ideal tracheal prosthesis.

Mineral profile of serum and cerebrospinal fluid (CSF) of 15 Himalayan Yak (adult female, n=8; adult male n=4 and young male,n=3) was studied in their natural habitat at an altitude of 3300 meters above mean sea level at Sangla in north western Himalayas. The macro and micro minerals estimated in serum and CSF were; Sodium, Potassium, Calcium and Magnesium and Zinc, Copper and Iron respectively. The values recorded among different Yak groups did not significantly differ from each other except serum iron and haemoglobin which were significantly higher (p<0.05 ) in young male Yaks compared to the adult male and female Yaks. An observation of great significance was considerably higher potassium and lower sodium level in Yaks compared to other bovine species of plains. The serum potassium values in some adult female Yaks were recorded as high as 10.4 mEq/l and the values varied between 6.6 to 9.8 mEq/l in young male Yaks. The serum Sodium values and Na:K ratios in Yak serum ranged between 117.5 to 122.6 mEq/l and 13.7 to 15.3 respectively. The possible relationship of high serum Potassium value with hypoxic conditions and hostile mountain environment has been discussed.

An investigation on the A/V(ampere/volt) gradient according to the concentration and the kind of solution in a electrolyzer is carried out to obtain the basic data on the ultrasonic application for the efficiency elevation of the hydrogen fuel production. KOH is selected as an electrolyte and concentrations are 0%, 10%, 20% and 30%. The solutions are city water, city water with nitrogen. distilled water and distilled water with nitrogen. The Electrochemical analyzer(BAS Co.) is used as a measuring device to observe the A/V gradient. And the limit of volt is from -3000mV to +3000mV. The 28kHz magnetic transducer is selected to give them ultrasonic forcing. In results, it is clarified that ultrasonic influences the A/V gradient in the electrolytic solution.

As the 21st century signifies an information-oriented society, the computer integration takes place in all walks of human presence. Needs for computer and network-integrated automation present new challenges in military as well as commercial facility systems engineering. Since the first intelligent building appeared in USA in 1984, it gradually became an essential capability for the building industry requirement these days. Intelligent Building System(IBS) is evolving to be very complex because there are many subsystems such as telecommunication(TC), office automation(OA), building automation(BA), security, construction environments, etc. During the planing phase of IBS development, therefore, a disciplined systems engineering must be performed to analyze stake- holder's requirements to build an optimized system while minimizing trial-and-error expenses and risks. This paper presents a conceptual design of BAS applying systems engineering methods. The contribution of this study includes the development of IBS subsystem specification for building automation subsystem, which is a part of IBS, using the methodology of requirement analysis, functional analysis, synthesis, and verification. A computer-aided systems engineering s/w, RDD-100, was used to improve the system design efficiency and to promote the product design knowledge management for reuse in later design programs.

Worldwide consumption of vegetable soybean bas been increasing recently, hence it is necessary to produce good quality of soybean in our farms. In the process of vegetable soybean production threshing and seperation work accounts for about 80% of overall labor. Therefore, developing of the vegetable soybean thresher is necessary to reduce the cost of labor. The purpose of this study is to acquire the basic informations to design of the vegetable soybeans-thresher. We make the experimental system which measure the physical properties and investigate the detachment forces. Also, We calculated the minimum speed of threshing cylinder. The result are as follows; 1. The average length of soybean stem is 68.2cm. 2. The length of soybean pods are seen as 61.3mm for 3 grain, 52.6mm fer 2 grains and 41.0mm fer 1 grain 3. The widths of soybean pods are seen as 14.1mm fer 3 grain, 13.8mm fer 2 grains and 13.4mm fer 1 grain. 4. The weights of soybean pods are seen as 4.1grams for 3 grains, 2.7grams for 2 grains and 1.4grams for 1 grain. 5. The average detachment forces of pods are seen as 1.5kgf for 3 grains, 1.2kgf for 2 grains and 0.8kgf for 1 grain respectively For 1 grain, the detachment force of pods ranges from 0.2kgf to 1.4kgf. For 2 grains, the minimum detachment force of pods is seen as 0.6kgf and the maximum one is seen as 2.5kgf. For 3 grains, the minimum detachment force of pods is seen as 0.7kgf and the maximum one is seen as 2.7kgf. 6. The minimum speed of threshing cylinder is shown 6.83m/s.

현재 우리 사회는 웹 1.0 시대를 지나 웹 2.0 이라는 새로운 웹 패러다임으로 진화하고 있다. 웹 2.0의 가장 큰 특징은 개방, 참여, 공유의 세 가지의 정신을 다양한 형태로 실현한다는 것이다. 이러한 웹 2.0을 가장 대표하는 것이 바로 위키이다. 위키는 온라인상에서 다수의 컴퓨터 사용자가 서로 연결되어 자유롭게 서로의 글을 공동 편집할 수 있도록 구현된 동적 프로그래밍 도구이다. 그러므로 온라인상에서 학생들간 협력학습을 구현해 내는데 있어서 아주 효과적일 수 있고 그러한 협력학습을 하는 과정에서 학생들은 자연스럽게 긍정적인 상호작용 기술들을 습득하게 될 것이다. 즉, 본 연구는 이러한 위키를 통한 초동학생들의 온라인 협력학습 과정이 공격적이고 비판적인 성향이 강한 학생들에게 필요한 배려심, 너그러움 등의 긍정적인 상호작용 기술을 습득하도록 하는데 도움을 줄 수 있다는 결과를 제시하고자 한다.
