The purpose of this paper is to show that there is a sure effect of the Extra Gigong Therapy(EGT) on Osteoarthritis patients. 1. Methods of the Spreading-Qi, Breathe naturally, concentrate the mind on Lower Dan(elixir field), When exhaling, Mindwill accompanies Qi to go to the Conception Vessel(CV) and Governor Vessel(GV), conduct Qi to the palms or fingers and emit Qi, with the emitting site touching or leaving the treated region. Qi helps vitality exalted, balance kept, and the circulation well-flowed. 2. For that, we made a schedule of joining some of Osteoarthritis patients who usually take anti-Osteoarthritis drugs, dividing them into two of groups. One is EGT-taken(group 1) and the other is not EGT-taken(group 2). 3. For insurance of analytic accuracy, we use the IEMD(Inner Energy Meridian Diagnosis). 4. In conclusion, there was significant differences between two of groups. Especially from the point of view of liver, kidney and spleen meridian pathways.

This is a paper on the validity of Extra Gigong Therapy(EGT) on Hypertension patients. We've treated hypertension patients EGT, used IEMD for analysis, so that come to these conclusions. 1. Average value of treatment group was 4.215, this is higher than one of control group. They had differences up to the standard. 2. Hypertension patients are divided into EGT treated group(treatment group) and non-treated one(control group). 3. Light stomach meridian has differences in treatment group and no differences in control group before and after EGT. That means EGT is effective. So does Spleen meridian. 4. With 12 meridians' electric potential values, we come to conclusion that EGT is likely to do hypertension patients good, especially on the point of view of liver, kidney, stomach and spleen meridian pathways. And bibliographies back up in this conclusion. 5. We classified hypertension patients into 4 factors: that is a spiritual factor, a physical factor, an eating factor and a circulation factor. Among these, a physical factor was seen of high frequency. There is a close connection between a physical factor and liver, kidney, spleen meridian pathways. The consequence was that subjects are suburban residents in the prime of time who had overworked.

Electronic Product Code Information Services(EPCIS) is an EPCglobal standard for sharing EPC related information between trading partners. EPCIS provides a new important capability to improve efficiency, security, and visibility in the global supply chain. EPCIS data are classified into two categories, master data (static data) and event data (dynamic data). Master data are static and constant for objects, for example, the name and code of product and the manufacturer, etc. Event data refer to things that happen dynamically with the passing of time, for example, the date of manufacture, the period and the route of circulation, the date of storage in warehouse, etc. There are four kinds of event data which are Object Event data, Aggregation Event data, Quantity Event data, and Transaction Event data. This thesis we propose an event-based data model for EPC Information Service repository in RFID based integrated logistics center. This data model can reduce the data volume and handle well all kinds of entity relationships. From the point of aspect of data quantity, we propose a formula model that can explain how many EPCIS events data are created per one business activity. Using this formula model, we can estimate the size of EPCIS events data of RFID based integrated logistics center for a one day under the assumed scenario.

This study focuses on hydrological changes caused by developments in the 13th, 14th (Motjarigol) district in Eun Pyoung New Town, Seoul on the basis of the Land Use Planning of development plan. Through analyses from the hydrological experiments about rainfall outflow using universal equation and amounts of infiltration through soils, the changes in amounts of overflows were estimated and the results were discussed from a urban ecological point of view. As a result, it has been predicted that the amount of rainfall outflow at post-development was dramatically increased, compared to pre-development. Installing of Derbris Dams and infiltration facilities were suggested as alternative plan to meditigate these changes. If we apply these alternatives, the rainfall outflow would be reduced up to 30% compared to the development plan without BMPs (Best Management Practice). In conclusion, it is proposed that once the ecological principles were considered during development planning process, we can minimize the adverse effects of developments to our environments.

RFID는 정보통신 외에 물류, 유통, 교통, 환경 등 다양한 분야에 적용될 수 있기에 유비쿼터스 시대에 없어서는 안 되는 기술로 각광받고 있다. 하지만 최근들어 RFID 보안의 무제가 거론되고 있어서 RFID의 정보보가 필요하게 되었다. 본 논문에서는 RFID 태그에 얼굴 생체 특징 정보를 효율적으로 저장하여 인증성을 보장하고 개인의 정보를 보호할 수 있는 알고리즘을 제안한다. 데이터양이 많은 생체 특징 정보를 개선된 선형판별 분석방법을 이용하여 특징 정보 차원을 감소시킴으로써 데이터양을 효과적으로 줄여 RFID 태그의 적은 메모리 영역내에 특징 정보를 저장하였다. 실험결과 사용자 인증율이 92%를 보였으며, 출입통제 시스템 및 전자 신분증 등에 활용 가능한 시스템으로 적용 가능할 것으로 보인다.

A long-term energy system in the future is expected to be based on the ideal circulation system between water and hydrogen in the sense that the hydrogen prepared from water eventually returns to water again after its use. Currently, with respect to the hydrogen energy system, it is predicted that the turning-point at which the production cost of hydrogen will become to be lower than that of fossil fuels would be after 2010. However, fuel cell technology would be able to be practically used for the applications to the transportation vehicles and small-scale power sources from 2004, and therefore, an efficient construction of the infrastructure covering hydrogen production and supply systems would be required with short-/mid-term technologies for the $CO_2$ reduction associated with fossil fuel utilization. In this paper, the hydrogen quantity available in domestic market has been estimated focusing on the hydrogen by-produced from domestic industries, and also the infrastructure for hydrogen-driven vehicles like fuel cell cars has been reviewed.

Natural ester has a higher biodegradability, flash and fire points, and a greater permittivity compared to conventional mineral oils. However, natural ester also has a higher pour point, viscosity, and water content. These characteristics hamper circulation and the electrical properties of oil-filled transformer. Thus, this paper applied electromagnetic-thermal-flow coupled analysis method to predict temperature distribution inside 154kV single phase power transformer using natural ester. It modeled in the actual appearance for the tank and winding of the power transformer to improve the accuracy of analysis and applied heat flow analysis that considered hydromechanics and heat transfer at the same time. It calculated the power loss, the main cause of temperature rise, from winding and core with electromagnetic analysis then used for the heat source for the heat flow analysis. It then compared the reasonability of result of measurement analysis based on the result acquired from temperature rise test using FBG sensor on the power transformer.

In this study a process simulation method was used to analyze the accumulation phenomena of anionic starch in the process white water as the closure level of a fine paper making process is increased. A pilot paper machine was used as a model process. Dynamic simulations of the influence of white water usage ratio and uncoated broke addition ratio on the variation of process variable was monitored as a function of time. Results from the dynamic simulations showed that the volume of reservoirs affected the dynamic behavior of the process. The dynamic behavior of flow rate and dissolved starch concentration in process units were different from each other. The speed of the change of dissolved starch concentration in process units was depend on the starting point of the change of dissolved starch concentration, the length of circulation loop, and the volume of reservoirs.
