In this paper, we devised a pulse rate detection system to provide basic clinical index of cold-hot diagnosis of oriental medicine. The system consists of pulse signal detection, respiration signal detection, electrocardiograph detection, A/D conversion and computer system parts. We define a pulse rate by a pulse count to the respiration period inspiration pulse rate by a pulse count to the inspiration period, and expiration pulse rate by a pulse count to the expiration period. The clinical experiments for normal Person to evaluate the pulse rate detection system show the pulse/respiration ratio of 4.30${\pm}$1.03, the pulse/inspiration ratio of 1.60${\pm}$0.32, the pulse/expiration ratio of 2.37${\pm}$0.75.

It is concentrated their efforts on expanding establishment mind like creating regular subject about establishment business of students and establishment business supporting center in University. Students creation enterprise club for establishment business with this hot wind of change and it seems to be success with hot wind of venture creation and gather many students for it. But practical result of research says that there are many problems like absence of education program, insufficient of professional leader, missing exact purpose so members decreased and activity itself piled up. Also creation business supporting system for student didn't conveyed to students evenly and effectively as much as original purpose and feeling effect is short of expectation. Therefore it will be required to reorganize supporting system and operate existed club to raise their ability of basic quality and gift that needs to do company activity and create basic mind about principal of free enterprise through activity of establishment enterprise by students. And we have to interest in their activity for creation enterprise with exact consciousness of purpose and prepare systematic, material, human supporting system that needs to establish enterprise with our knowledge and ability.

Considering the relatively large amount of stable flexural teat results available for steel fiber reinforced concrete (SFRC) and their dependency on the constitutive behavior of the material, a technique called “System Identification” is used for interpretating the flexural test data in order to obtain basic information on the tensile constitutive behavior of steel fiber reinforced concrete. “System Identification” was successful in obtaining optimum sets of parameters which provide satisfactory matches between the measured and predicted flexural load-deflection relationships.

The operating support systems such as CSMS, TLMOS, and SLMOS may be related each other. At the present time, UNIX system is most popular operating system. TLMOS and SLMOS have been developed under the UNIX environment and using C language. On the other hand CSMS was built on HP RTE O. S. using Pascal. When we constuct the operation and maintenance organization by networking several operations support system, the interface of intersystem must be simple and the integrity of whole system must be kept. It is somewhat valuable to investigate transfering CSMS from RTE O. S. to UNIX in order to integrate operations and maintenance systems. Here, we give a basic material about porting CSMS in UNIX.

이 연구는 조선시대 사찰 주불전 발굴지를 복원하기 위한 기초자료를 구축 방식을 제안하고자 하였다. 조선시대는 발굴지와 현존 주불전이 동시에 존재하는 유일한 시기이므로 평면계획의 비교를 통하여 복원을 위한 기초자료를 구하고자 하였다. 이 연구에서는 상관성이 있는 비교항목들을 선정하여 순차적으로 여러 단계의 비교를 통하여 복원을 위한 가장 적합한 사례들을 찾아낼 수 있도록 하는 목적을 가지고 기초자료 구축 방식을 제안하고자 한다. 따라서 이 연구에서는 비교항목의 선정과 비교 순서, 그리고 사례의 비교방식 등이 모두 중요한 요소로서 고려되어야 한다. 이 연구에서는 5개의 3x3칸 주불전 발굴지를 대상으로 70개의 현존 주불전과 비교하여 최초의 비교에서 4개의 사례를 선정하였다. 그리고 다시 한 번 비교를 통해서 사례들을 좁혀보았다. 비교항목으로서 면적과 정면/측면 길이의 비율은 서로 관련성이 있어 둘 다 만족하는 사례가 있어 복원의 기초자료로서 활용할 가능성이 높았다. 하지만 정면어칸길이/협칸길이의 비율과 측면어칸길이/협칸길이의 비율은 둘 다 만족하는 사례가 없어 비교항목 서로간의 관련성이 적음을 알 수 있었다. 이러한 자료 구축방식은 비교 항목, 비교 순서, 비교 사례의 선정 수량 및 범위 등에서 고려할 점이 많아서 장단점을 가지고 있음을 보여주었다. 그리고 다양한 방향으로 확장할 수 있어 그 가치가 높으며 자료구축의 다양성에 의해 개별적인 특징이 많은 발굴지에 보편적으로 적용할 수 있다는 장점을 가진다.

Appropriate design/manufacturing conditions, to give outstanding material properties to the $Si_3$$N_4$-BN and AIN-BN based composite materials, will be investigated using the experimental design methods. Ultra-precision machinability of the developed ceramics will be systematically studied in the viewpoint of microstructure and material properties. Also, finite element methods will be applied to define basic principles to significantly improve machinability and various properties. Basic experiments will be performed to develop optimum ultra-precision machining technologies for the developed ceramics. For ultra-precision lapping machining, need to develop a ultra-precision lapping system, suitable metal bonded diamond wheel, and appropriate condition of ultra-precision lapping machining.

The 1st development of "Human Powered Aircraft(HPA)" in Korea has been conducting by KAFA(Korea Air Force Academy) from Aug. 2008 to now. HPA is an aircraft powered by directly human energy. The thrust provided by the human power may be the only source and that is weak. Therefore, light weight and strong structure is first requirement. In this paper, treating a basic conceptual design of HPA and material property and material choice for HPA. Also analysing the structure and checking the safety of HPA.

The testing philosophy and control schemes are investigated and applied to construct the Automatic Microwave Leakage Inspection System (AMLIS) . AMLIS is consists of three major parts such as Material Handling Mechanism, Fine Positioning Mechanism and Scanning Mechanism. The material Handling unit is designed to perform loading and unloading microwave oven onto the testing point by pneumatic cylinder and vacuum pump. The Fine positioning part includes X-Y-.THETA. table and distance sensing equipment. The scanning part is composed of five SCARA robots, which traverse X-Y-Z catesian coordinates respectively. The leakage testing probes are placed at the end of this each robot then the path and speed are both controlled via microprocessors. A performance test of this system combined with electric parts and software is done and the basic major function of system are accomplished.

Recently, a study of intellectual smell recognition system is applied for the various fields such as control of food processing and survey of decay. A basic gas recognition system was implemented gases using four metal oxides semiconductor sensors as inputs. A CPLD chip of twenty thousand gates level was used for this purpose. The CPLD chip was designed and the availability of the one chip smell recognition system was tested.
