Objective: Ayurveda is a complementary and alternative medical (CAM) system that has been practiced primarily in the Indian sub·continent for 5,000 years. As need for CAM increases, interest in Ayurveda is drawing more attention in Western countries. But in Korea, understanding of Ayurveda is superficial due to a lack of information and research. In this article, we investigated not only the philosophical features of Indian Traditional Medicine, but its relationship with Korean Oriental Medicine. Methods: From April to August 2004, we sought mutual cooperation through observation at research institutes (Central Council for Research in Ayurveda and Siddha, National Institute of Ayurveda, Institute of Medical Science, Pharmacopoeial Laboratory for Indian Medicine) and performed on-the-spot surveys & discussions. Results & Conclusions: We conclude that the philosophies of Indian Traditional Medicine could extend those of Korean Oriental Medicine. Adopting some promising Indian Traditional Medicine techniques such as PanchaKarma and KsharaSutra treatments which have been shown to have efficacy and safety could contribute to the development of Korean Oriental Medicine's internal & external medical treatment. Further studies of Indian Traditional Medicine are needed.

Online parallel machine scheduling problems have been studied by many researchers and enormous results are appeared in the last 40 years. With the development of scheduling theory and application, new online scheduling problems where the partial information is known in advance, that is, semi-online, gained much interest due to their increased application in practice. So we consider the online scheduling of three machines with general eligibility and its semi-online variant where the total processing time is known in advance. For the online and semi-online problems, we develop algorithms with competitive ratio of 5/2 which are shown to be optimal.

It is of great practical interest to decide when to stop testing a software system in the development phase and transfer it to the user. This decision problemcalled an optimal software release one is discussed to specify the a, pp.opriate release time. In almost all studies, the software reliability models used are nonphomogenous Poisson process(NHPP) model with bounded mean value function. HNPP models with unbounded mean value function are more suitable in practice because of the possibility of introducing new faults when correcting or modifying the software. We discuss optimal software release policies which minimize a total average software cost under the constraint of satisfying a software reliability requirement. A numerical example illustrates the results.

Customer satisfaction is becoming an increasingly salient topic in many firms and in academic research. One main rationale behind this interest is that customer satisfaction is believed to be associated with fruitful customer re-visit from the firm's point of view. Some country already had index models which can measure the degree of customer satisfaction. But, such models are ordinary models which used generally the scope of nation-wide /industry. Therefore, we needs some modifications to measure customer satisfaction for specific product & service and to provide the valuable feedback to specific firms. In this Perspectives, this study will evaluate the customer satisfaction index about automobile company and analyze it's result for valuable feedback. This study will present a model for an integrated customer satisfaction evaluation system which used structural equation modeling. Through this study, we anticipate that it will offer the measuring method about customer satisfaction and some guideline for product design process.

Wind power system attracts most interest because of high-energy efficiency with environment-friendly. Small scale wind power applications requires a cost effective and mechanically simple generator in order to be a reliable energy source. The use of direct driven generators, instead of geared machines, reduces the number of drive components, which offers the opportunity to reduce costs and increases system reliability and efficiency. This paper presents the development of a coreless axial-flux permanent magnet(AFPM) generator for a urban wind power system. It is analyzed by electromagnetic simulation program Maxwell 3D

The number and percentage of people in need of a wheelchair are increasing every year, both manual and power wheelchair users express an interest in monitoring their weight. However, frequent measurements are not possible when relying on hospital scales and models designed for home use are expensive. So the goals of this study became to create a product that's relatively inexpensive, portable, and precise, which means varying little between measurements. Secondary goals were ease of use, compatibility with different kinds of wheelchairs, and accuracy, which means achieving proximity to an actual value and isn't as important when trying to monitor increases or decreases in weight.

It became new social interest for children to have their own appropriate physical, mental, social environment as one independent identity, In these social atmosphere, new design method and standard of children's residence, education, playing environment which can fill their desire. When home and school are the first places to meet the world and learn, museum and science hall are the representing places to provide education and entertainment, especially to preschoolers, they are the prior education system. it is the most important these science halls to give children potential familiarity of science rather than direct knowledge. Also these places should be stepping stones of the process of intellectual growth as foundation stones for future science education. On this research i will provide a direction to space planning of children's science hall, extended to children' museum studying display producing of playing conception, the necessary element of children's physical, mental, social behavior development process.

Automatic measurement system is required since cycle time and cost of production are increased by various factors in manual systems. This paper presents a machine vision based prototype measurement system for the automotive axisymmetric shape parts which are generally measured by a manual system that is required the tolerance of the part is very small on each machined surface. This measurement system adopts a method in which optical lens is transferred along the profile of the part to minimize measurement cycle time. The main interest of this paper is a development of an optimum measurement algorithm to the outside diameter of the parts that can be applied to various combinations of hardware. The operating system used to implement the whole system is Window XP and corresponding environment.

In the recent years, as the research and the development of micro and precision machinery become active, the interest of micro actuators using SMA(Shape Memory Alloy) has been increased. The dynamic characteristic analysis of SMA is necessary for actuator application and many common researches report the material characteristics of SMA sufficiently. However, the research on dynamic characteristics is very deficient. In this paper, the helical spring are fabricated with NiTi SMA wire of high resistivity, The force, response speed, temperature, and displacement are measured by digital force gauge, infrared thermometer, and laser displacement sensor so that the dynamic characteristics of this SMA is analyzed. Also, bidirectional actuator was fabricated and experimented for its performance.

Plant biotechnology involving genetic modification has been rather controversial. However, the major issues related to safety are being addressed by continued improvements in technology. Some of the related facts will be highlighted to set the tone for a scientific discussion on the possibilities of using the technology for crop improvement. Our main research interest is to understand the molecular regulation of shoot bud regeneration in plant tissue culture, which is essential for crop improvement by biotechnology. We have isolated and characterized some genes that are associated with adventitious shoot regeneration. These include a MADS-box cDNA (PkMADS1) from paulownia kawakamii, which regulates vegetative shoot development and in vitro shoot regeneration from leaf explants. Another gene we have characterized from petunia codesfor a cytokinin binding protein (PETCBP). Preliminary functional analysis of this gene indicated that this also affects adventitious shoot bud initiation. Also, the antisense suppression of this gene in petunia causedexcessive branching. Results from our work and selected other publications will be used to highlight the possibilities of manipulation of such genes to improve crop species.
