  • To develop the Korean standard differentiation of the symptoms and signs for the stroke(KSDS), the committee on Stroke Diagnosis Standardization of traditional Korean medicine(TKM) was organized dy nineteen experts in college of Korean medicine. On July 9th 2005, the second consultation meeting was held in Daejeon, Korea. Fifteen experts of the committee attended the meeting and they discussed the KSDS and came to a consensus. The 15-member committee consensus was as follows: First, board members defined the stroke on the basis of TKM. Second, they divided the symptoms and signs of stroke into five categories- fire and heat, dampness and phlegm, blood stasis, qi deficiency, yin deficiency. Third, the symptom indicator of each differentiation type for the stroke was recommended. KSDS-1 will be applied to the clinical practice and revised.

  • Cordyceps sinensis has been clinically used for the treatment of recovering fatigue, promoting the production of body fluid and qi, resolving sputum and arresting cough. Recent studies showed that Cordyceps sinensis produced immune-modulatory, anticarcinogenic and antioxidative effects. But, there are lack of studies regarding the effects of Cordyceps sinensis on the asthma. So, this study was performed to investigate the oral administrated effects of this herb against the disease. Asthma was induced to Balb/c mouse by i.p. injection and aerosol immunization with ovalbumin, and the change of the eosinophil number in the bronchoalveolar avage fluid(BALF) was observed. Concentrations of Interleukine-4(IL-4), Interleukine-5(IL-5) in BALF and splenocyte were assessed by ELISA, ImmunoglobinG(IgG) and ImmunoglobinE(IgE) from serum were calculated by same method. We found that the effects of Cordyceps sinensis in asthma mouse was implicated in reductions of IL-4, IL-S released from type2 T helper (Th2) cell, and decreases of IgE from plasma cell. These findings suggest that Cordyceps sinensis can produce anti-asthmatic effect, which may play a role in allergen-induced asthma therapy.

  • Recent studies have revealed the efficacy of incorporating delayed channel state information at transmit side (CSIT) in transmission scheme design. This paper focuses on transmit precoder design to maximize the ergodic sum-rate in a two-user Multiple-Input Single-Output (MISO) system with delayed and statistical CSIT. A new transmit strategy which precodes signals in all transmit slots is proposed in this paper, denoted as all time-slots precoding Alternative MAT (AAMAT). There is a common procedure in conventional delayed-CSIT based schemes, which is retransmitting the overheard interferences. Since the retransmitting signal is intended to both users, all previous schemes tend to use only one antenna. We however figure out an improvement in spectral efficiency could be realized if all antennas can be utilized. In this paper, we detail the design of the procoder which enabling all antennas and also we compute a lower bound of the ergodic sum-rate in an ideal condition. In addition, simulation results demonstrate the superiority of our proposed scheme.

  • Buck-Boost LLC (BBLLC) converters based on a PWM + phase control strategy are good candidates for high efficiency, high power density and wide input range applications. Nevertheless, they suffer from large computational complexity when it comes to calculating the optimal phase for ZVS of all the switches. In this paper, a method is proposed for a microcontroller unit (MCU) to calculate the optimal phase quickly and accurately. Firstly, a 2-D lookup table of the phase is established with an index of the input voltage and output current. Then, a bilinear interpolation method is applied to improve the accuracy. Meanwhile, simplification of the phase equation is presented to reduce the computational complexity. When compared with conventional curve-fitting and LUT methods, the proposed method makes the best tradeoff among the accuracy of the optimal phase, the computation time and the memory consumption of the MCU. Finally, A 350V-420V input, 24V/30A output experimental prototype is built to verify the proposed method. The efficiency can be improved by 1% when compared with the LUT method, and the computation time can be reduced by 13.5% when compared with the curve-fitting method.

Methods : After collecting medical texts related to 'Specially Selecting Yangming', its meaning and clinical application were examined thoroughly. Results : 1. The meaning of 'Specially Selecting Yangming' was identified in different ways according to the meaning of 'Yangming.' It was perceived as Stomach, Yangming meridian, Stomach meridian of Foot Yangming, Spleen and Stomach, Intestine and Stomach by medical experts. 2. Chen Wu-ze and Liu Wan-su understood Wei disease as a form of consumption, and regarded 'Specially Selecting Yangming' as tonifying Yangming while Zhang Zi-he put emphasis on Communicating Stomach Qi(胃氣) through vomiting or purgation. Sun Yi-kui insisted on applying it as a precaution. 3. Li Dong-yuan emphasized the cause of Wei disease to be Damp-Heat in the Summer and suggested Qingshuyiqitang and Qingzaotang as remedy. 4. Zhu Zhen-heng's Purging the South and Reinforcing the North is a more fundamental way of treating Wei disease by stimulating the Water-Fire Axis. Conclusions : Through a diachronic study of 'Specially Selecting Yangming' and its remedy, most medical experts regarded 'Specially Selecting Yangming' as tonifying Yangming, but tonifying Liver and Kidney was thought to be a more fundamental treatment.

  • The small PWR has been paid more and more attention due to its diversity of application and flexibility in the site selection. However, the large core power density, the small containment space and the rapid accident progress characteristics make it difficult to control the containment pressure like the traditional PWR during the LOCA. The pressure suppression system has been used by the BWR since the early design, which is a suitable technique that can be applied to the small PWR. Since the configuration and operating conditions are different from the BWR, the pressure suppression system should be redesigned for the small PWR. Conducting the experiments on the scale down test facility is a good choice to reproduce the prototypical phenomena in the test facility, which is both economical and reasonable. A systematic scaling method referring to the H2TS method was proposed to determine the geometrical and thermohydraulic parameters of the pressure suppression containment response test facility for the small PWR conceptual design. The containment and the pressure suppression system related thermohydraulic phenomena were analyzed with top-down and bottom-up scaling methods. A set of the scaling criteria were obtained, through which the main parameters of the test facility can be determined.

  • The purpose of this paper is to examine the development of the content of Dao-tong during the Tang and Song Dynasties. This paper examines the transition of Dao-tong in the following three stages. First, Han-yu(韓愈) defined that Ren-Yi(仁義) is the content of Dao-tong. Second, Sun-fu(孫復) and other Confucian scholars in the Northern Song Dynasty stipulated that a broader meaning of Confucian Dao is the content of Dao-tong. Third, Qi-song(契嵩) and Dao-xue-jia(道學家) in the Northern Song Dynasty insisted that Zhi-Zhong(執中) should be a content of Dao-tong. This Confucian Orthodoxy is changed into the philosophical theory of human-nature and heart by Dao-xue-jia in the Northern Song Dynasty.

  • Experimental research on flow characteristics of open natural circulation system was performed, to figure out the mechanism of the open natural circulation behaviors. The influence factors, such as the heating power, the inlet subcooled and the level of cooling tank on the flow characteristics of the system were examined. It was shown that within the scope of the experimental conditions, there are five flow types: single-phase stable flow, flash and geyser coexisting unstable flow, flash stable flow, flash unstable flow, and flash and boiling coexisting unstable flow. The geyser flow in flash and geyser coexisting unstable flow is different from classic geysers flow. The flow oscillation period and amplitude of the former are more regular, is a newly discovered flow pattern. By drawing the flow instability boundary diagram and sorting out the flow types, it is found that the two-phase unstable flow is mainly characterized by boiling and flash, which determine the behavior of open natural circulation respectively or jointly. Moreover, compared with full liquid level system, non-full liquid level system is more prone to boiling phenomenon, and the range of heat flux density and undercooling degree corresponding to unstable flow is larger.
