Korean foodservice's circulation industry has been developed with enforcement plan of circulation modernization for the purpose of circulation construction improvement in 1992 and revision plan of circulation modernization plan preparing circulation market opening in 1995. But Korean circulation step is still in an early stage compare the advanced nations, so it has a bad effect in case the price competition and the profits, A circulation industry has originally premodenization. But it could be changed leading industry of 21 century, because it can used not only latest technique through information network but also leisure market of consumption industry. We must be enough a purchase condition of direct transaction from a minimum of circulation in order to compete with new business industry of advanced nations. Threfore the scheme for the development of foodservice industry should be improve a circulation management environment of circulation company, also the government should be improve the system in the policy. Both the government and the enterprose must reinforce efforts for high level competition more than the present states. From the view point of the bedelayed industry of all industries, the chance of new business will be created more than others.

According to the increase of demand for human organs such as kidney, heart, pancreas, joint, and cornea for therapeutic transplantation, the production of alternative organs based on Gnotobiotic Pigs gains a lot of concerns all over the world. However, it is not common to design and build Gnotobiotic Pigs' facility, and there are only a few those facilities and planning principles for them. Considering the situation above, this paper tries to develop planning guidelines for space organization and circulation system of standardized Germ Free Pig's facility on the bases of case analysis. The results of this study are as follows. At first, four swine farms including a Gntobiotic Pig's facility has been analysed from the point of space organization and circulation system. Secondly, the space zoning of Gnotobiotic Pigs' facility has been proposed into 5 groups : pigs' area, adminstration area, operating room and laboratory, service area, and mechanical area. Space components of each group have been presented also. Finally, circulation system of Gnotobiotic Pigs' facility has been explored from a operational point of view. This, also, includes human circulation, pig's circulation, and goods' circulation. This study has some limitations because it does not consider the SOPs(standard operational policies) of that facility to the fullest measure and does not suggest space area of each part, either. Despite of some weaknesses, it is expected that this study can give some useful guidelines for the design and planning of Germ Free Pigs' facilities.

This study was performed to estimate the characteristics of the organic wastewater treatment and bed porosity with the circulation velocity in the anaerobic fluidized bed biofilm reactor. The results were as follows; 1. With Increasing circulation velocity the fluidized bed expanded smooth and with increasing initial particle volume the fluidized bed was increased. 2. With increasing circulation velocity the gasproduction was increased, but at 1.Scnt/sec of circulation velocity AFBBR showed the highest value of methane production rate per removed COD. Therefore, for the purpose of economical operation in AFBBR, 1.5cm/sec of circulation velocity was optimum 3. The microorganisms were colonized in the crevice of the media. 4. On fluidization, COD, VA,55 profiles with the reactor height were not showed. In conclusion, AFBBR suit the organic wastewater treatment's purpose, and at 1.5cm/sec of circulation velocity the system is economical in an energy Point of view.

The planning of circulation area and circulation path are very important elements for layout of interior space of housing. This study is, therefore, aimed at synthetical review of that area from a functional, structural and socio-cultural point of view as well as typological analysis of that area. In the interior space of housing the networking of spaces according to the circulation route imply divers aspects of independent or dependant significances. It is thus, closely related with to whether circulation area open or closed, whether circulation path concentrated or distributed, and whether it passes Individual rooms or not. With regard to relationship with public and private spaces, there are many grounds for combining each other. This study also tried to develope program for planning of circulation system, utilizing typological analysis of them. At the same time this study suggests examples for layout of housing spaces. It is expected that the results represented In the form of systematic diagram will deserve to be a tool for providing an appropriate solution to the problem of diversity of user's needs.

PyoBon GeunGyul - one of the twelve regular meridians theory - play a important role on the principle of point selection and point prescription in acumoxibustion. PyoBon explain the connection of the concentration and diffusion of channel qi, GeunGyul explain the relation of both poles of channels flow. So, Geun and Bon means the starting point of channel qi, and Pyo and Gyul means the terminal point of channel qi. But the flow of channel qi on PyoBon GeunGyul different from today's circulation courses of twelve regular channels based on Kyungmaek(經脈) chapter of Youngchu. Thus this study investigate the contents of PyoBon GeunGyul and consider its connection with channel flow. The results are as follows : 1. PyoBon GeunGyul theory explain that the relation of the limbs and trunk at meridian and emphasize that the connection of meridian and the importance of the limb acupoints. 2. PyoBon GeunGyul theory can be understandable in the view of the primordial qi and explain that the primordial qi of twelve regular channels acts from the limbs to the trunk. 3. PyoBon GeunGyul theory is based on the system of primordial qi channel which circulates from fingers and toes facing toward heart or the head, different from today's circulation courses of twelve regular meridians. 4. PyoBon GeunGyul theory act as a basis of principle of a part or distant point selection which applicated widely in acumoxibustion.

This paper reviews the main aspects of cardiovascular system dynamics with emphasis on modeling hemodynamic characteristics using a lumped parameter approach. Methodological and physiological aspects of the circulation dynamics are summarized with the help of existing mathematical models: The main characteristics of the hemodynamic elements, such as the heart and arterial and venous systems, are first described. Lumped models of micro-circulation and pulmonary circulation are introduced. We also discuss the feedback control of cardiovascular system. The control pathways that participate in feedback mechanisms (baroreceptors and cardiopulmonary receptors) are described to explain the interaction between hemodynamics and autonomic nerve control in the circulation. Based on a set-point model, the computational aspects of reflex control are explained. In final chapter we present the present research trend in this field and discuss the future studies of cardiovascular system modeling.

The purpose of the present experimental study is to apply multi-point simultaneous measurement by PIV(Particle Image Velocimetry) to high-speed flow region within a domestic boiler circulation pump. Two different kinds of flow rate($27{\ell}/min,\;19{\ell}/min$)are selected as experimental condition. A volute casing and Impeller made of transparent Polycarbonate were made for the easy access of the illumination laser via fiber optical line and cylinder lens assembly to the measuring region. A CCD camera is syncronized with AOM to acquire clear original particle images. Optimized cross correlation identification to obtain velocity vectors is implemented by direct calculation of correlation coefficients. The instantaneous and time-mean velocity distribution, velocity profile and kinetic energy are represented quantitatively at the full-scale region for the deeper understanding of the unsteady flow characteristics in a commercial circulation pump.
