Wang Cheong-Im(1768-1831) in the Ching dynasty conducted the therapy of blood statis syndrome using the methods for promoting blood circulation and removing blood statis in accordance with the description in the book Uirimgaechak(醫林改錯). Thus, this study examined his methods for promoting blood circulation and removing blood statis, therapy of blood statis syndrome and mechanism of function. Since the blood statis symptoms varied on the parts where the blood statis were occurred, the therapy for promoting blood circulation and removing blood statis applied different treatments and drugs depending on the symptoms. The therapy also valued much of qi and blood. Qi is important to the human body so that the therapy replenished qi and simultaneously promoted the blood circulation as mainly focusing on the regulation of the qi flow. Moreover, the therapy adjusted the level of removing blood circulation and rate of replenishing qi. The degree of prescription and drug was differentiated in treating a variety of blood statis because of the difference in the seriousness and characteristics of blood circulation, amount and application of drug and combination of drugs. The therapy was careful about the regulation of qi for the replenishment of qi and the nurishment of blood for the promotion of blood circulation. If the blood circulation was blocked, the blood statis was formed. Accordingly, the phlegm and the blood statis were closely related. Then, the phlegm and blood statis were simultaneously treated. The therapy divided the properties of blood statis into the stagnant excess syndrome, the stagnant deficiency syndrome, the stagnant cold syndrome and the stagnant heat syndrome and treated the patients suitable for each symptom. The function of mechanism in the treatment using the methods for promoting blood circulation and removing blood statis was divided into the stagnation of blood and interruption in blood circulation. The therapy laid stress on promoting blood circulation and removing blood circulation. With such emphasis, the therapy facilitated the circulation in the bloood vessel, prevented the coagulation of blood, removed the blood statis and promoted the metabolism. Then, the physiological function and pathological change internal organs were improved. Furthermore, the therapy strengtened the heart and promoted the blood circulation by improving the systemic blood circulation. Moreover, the therapy facilitated the micro-circulation by adjusting the balance of body.

The concentration of cohesive suspended sediment is determined by the circulation of water and the material dispersion. The equations of the two-dimensional, depth-integrated dispersive transport are the Reynolds equation, continuity equation, and advection-dispersion equation based on the Fick's law. A finite difference method has been applied to two models of circulation and dispersion transport. The circulation model is solved by the explicit scheme and the dispersion transport model is solved by multi-operational scheme. It is investigated wheter advective terms are included when the equation of circulation is applied to the model. For advection-dispersion equation, it was also investigated about variations of suspended sediment concentration with respect to the critical shear stresses.

The library circulation service, which refers to the lending of library material outside of the library, is a basic and essential service provided by the library. However, changes in the library circulation service are being made according to a more management-oriented operation and the development of information technology. Consequently, the library faces a paradigm shift 'from library-centered service' to 'user-oriented service' and experiences changes in library circulation service due to the growth of library networks. Also, each library, in order to respond to the changes, tries to specialize the library circulation service by utilizing available library resources. In that context, this study, through the case study of the "Chack DanBi" library circulation service of Eunpyeong Public Library, investigates and analyzes the changing library circulation service according to the above perspectives; seeks the meaning of the service; and aims at enhancing our understanding of the library circulation service.

Continuous industrial development has led to a better quality of life for everyone, even further accelerating industrial growth. Industrial development, however, has also caused environmental degradation, which is posing a serious threat to humanity. It has also encouraged the indiscriminate use of limited resources, causing resource depletion. Efficient resource management based on resource circulation is critical to saving resources. Resource circulation methods are as follows: reducing the use of resources in the manufacturing process, recycling used or reprocessed products and reusing used resources without being reprocessed, remanufacturing with end-of-life products with disassembled parts. Furthermore, remanufacturing process including cleaning, inspection, repairing, and reassembling facilitate performance level as well as new typical products. It is noteworthy that the remanufacturing of machine tools can significantly save resources because their structural parts are substantially large in size. Machine tools have served as a foundation for the manufacturing industry, which has driven Korea's industrial development. Nevertheless, a few research has been reported for remanufacturing technology with used machine tools. Relevant research of developing a remanufacturing process chart and method is prerequisite for saving the resource and environments.

Reservoirs, which make up most of South Korea's reservoirs, are located in rural areas. In the case of rural reservoirs, about 75% have been reported over 50 years old aged reservoirs constructed before the 1960s. Reservoirs are important facilities that store and supply water necessary for daily life. However, if it is destroyed, the reservoir can cause a lot of damage, so continuous management is necessary. As a method for strengthening old reservoirs, a method using cement has been widely applied. However, OPC is a product that uses a lot of carbon dioxide and natural resources. Therefore, the amount of cement should be reduced. Against this background, in this study, the ground injection material of utilizing circulation resources was applied to the site. Applied reservoirs have been around for 75 years and leaks have occurred in some sections. The application method was constructed in two rows, up to a depth of 12m. After reinforcement, the electrical resistivity test was conducted three times. As a result, similar resistance was shown at 1 month after construction. And after 6 months, the saturation area decreased. And the performance after reinforcing the aged reservoir was examined. As a result of the review, this study confirmed that the applicability was equivalent to that of OPC, and the excellent performance of reinforcing the aged reservoir was shown.

So far, we have pursued only convenient and efficient growth of economy, as a result, environment surrounding us has been destroyed and the rights of our existence gotten to be even threatened. We need to ensure our lives and at the same time, need a power with which agriculture undertakes global circulation structure and a power that is able to preserve our environment we live per so. Therefore, in the near future, the final objectives of agriculture structure for 21st century would be to increase productivity of highly developed agricultural products in accordance with the ecosystem and a recycling agriculture. What is a recycling agriculture\ulcorner In the narrow sense, it means provisions-producing- system related to interactive recycle of material among forestry, livestock husbandry and seeding agriculture. In the broad sense, it means to produce credible agricultural product by keeping balanced resources via conversion to complete degradable material of organic wastes produce within rural village. Based on this concept, finally, our goal is to construct the resources recycling community. Environment friendly agriculture ⇒ organic agriculture ⇒ recycling (circulation) agriculture ⇒ construction of community with resources recycling. Therefore, in order to construct recycling agriculture, most of all, it is considered that the following, it should be established reasonable standard amounts for fertilizer, manure and liquid fertilizer based on results of soil test by each region, nature-recycling form of crops production and livestock production systems by maximizing utilization of different recycling byproducts occurring in the crop producing process by each region.

As climate changes and abnormal climates have drawn research interest recently, many countries utilize the GCM, which is based on SRES suggested by IPCC, to obtain more accurate forecast for future climate changes. Especially, many research attempts have been made to simulate localized geographical characteristics by using RCM with the high resolution data globally. To evaluate the impacts of climate and landuse change on water resources in the Han-river basin, we carried out the procedure consisting of the CA-Markov Chain, the Multi-Regression equation using two independent variables of temperature and rainfall, the downscaling technique based on the RegCM3 RCM, and SLURP. From the CA-Markov Chain, the future landuse change is forecasted and the future NDVI is predicted by the Multi-Regression equation. Also, RegCM3 RCM 50 sets were generated by the downscaling technique based on the RegCM3 RCM provided by KMA. With them, 90 year runoff scenarios whose period is from 2001 to 2090 are simulated for the Han-river basin by SLURP. Finally, the 90-year simulated monthly runoffs are compared with the historical monthly runoffs for each dam in the basin. At Paldang dam, the runoffs in September show higher increase than the ones in August which is due to the change of rainfall pattern in future. Additionally, after exploring the impact of the climate change on the structure of water circulation, we find that water management will become more difficult by the changes in the water circulation factors such as precipitation, evaporation, transpiration, and runoff in the Han-river basin.
