According to the literatural study on the Acupuncture & Moxibustion and Traumatherapyof hysterorrhea, the results were as follows. 1. The acupuncture & moxibustion of hysterorrhea is focussed on bloody uterine discharge, leukorrhea and we must carefully diagnose the etiology & the machanism of disease. 2. The causes of hysterorrhea are dampness, impairment of seven emotion, irregular food intake, excessive intercourse and they are impotantly related to liver, spleen, kidney, the ren channel, the chong channel. 3. The diagnosis is grossly divided into the flowing downward of damp-heat, the weaknessof the qi of the spleen, dificiency of yuan of the kidney and according to the each diagnosis, we should select adquate points representing the treatment of cooling(zhongji, yinlingquan, xingjian, etc), desiccation, heiping qi(qihai, zusanli, sanyinjiao, etc), tonificating yang (guanyuan, mingmen, shinshu, etc). 4. The moxibustion is the warming the lower jiao and eliminating the cold, the points are the mingmen point, the zhongji point, the guanyuan point, etc. 5. Besides the acupuncture & moxibustion of hysterorrhea, we can make use of acusetor, ear acupuncture, endermosis, dong shi shen fa. 6. As of traumatherapy of hysterorrhea, fumigation,abluent and soppository are generally used. and the prescriptions as GAMISASANGSAN, BANSUKSAN are used. 7. The medical herbs used on the treatment of hysterorrhea are the tonificating yang, dissipeting, desiccating medicines generally composed of CNIDII FRUCTUS, ALUMEN, ZANTHOXYLI FRUCTUS.

Objectives : I intended to find out the origin and development of symptom discrimination based on theory of triple energizers before Tang Dynasty(唐代). Methods : I extracted the topic-related contents from books in this era. After arraying them in a chronological order, I analyzed the materials. Results : The author in Zhong Zang Jing(中藏經) first mentioned that symptom of Huo Luan(霍亂) was deeply related with triple energizers. Ge Hong(葛洪) did not only come out with some symptoms and mechanisms for Shang Han(傷寒) and Za Bing(雜病), but also applied them to their usages for herb medicine. Chao Yuan Fang(巢元方) suggested its symptoms were more closely related with Shang Han and Za Bing than before. For the first time, Chao subdivided its symptoms to both cold-heat and weakness-strength sides. Sun Sai Miao(孫思邈) supplemented its discrimination invented by Chao(巢元方), adding more symptoms and prescriptions for triple energizers. Wang Tao(王燾) showed more prescriptions for triple energizers than before, and initially designed the discrimination for Huo Luan, diabetes(消渴), and epidemic Wen Bing(溫病). Conclusions : Before Tang dynasty, the symptom discrimination based on theory of triple energizers had been originated and developed for the purpose of repairing Za Bing, not just treating Wen Bing.

고효율 LED를 얻기 위해서는 LED의 내부 양자효율과 외부 양자효율이 높아야 한다. 현재 GaN-Based LED의 내부 양자효율은 결정의 질의 개선 및 이중이종접합 또는 다중양자우물 구조와 같이 활성층의 캐리어 농도를 높이는 접합구조로 설계되어 거의 100%에 가까워졌다. 그러나 외부 양자효율은 반도체 재료의 높은 굴절률로 인하여 외부로 탈출하지 못하고 내부로 전반사 되어 반도체 내부에 갇히게 되는데 이처럼 갇힌 빛은 반도체와 중간 Interface에 TIR(total internal reflection) 또는 반사판에 의해 계속적으로 반사 된다. 그러므로 이를 해결하기 위한 플립칩 구조, 포토닉 크리스탈 등의 여러 가지 방법들이 제시되고 있지만 아직도 더 높은 외부 양자 효율의 개선을 요구하고 있다. 본 연구에서는 새로운 형태의 반사판(Al) 즉 p-GaN과 반사판 사이의 interlayer로 반사판과의 오믹 접촉을 고려한 Embo type의 NiO를 구현하여 반사된 빛의 방향을 내부반사를 줄일 수 있는 방향으로 변화시킴으로써 광 추출 효율의 향상을 기대할 수 있게 되었다.

Next-generation (4G) systems are designed to support universal frequency reuse (UFR) to achieve best use of valuable spectra. However, it leads to undesirable interference level near cell borders. To control this, 4G systems adopt techniques, such as network multiple-input multiple-output (MIMO) and inter-cell interference coordination (ICIC), to improve cell-edge throughput. Network MIMO aims at mitigating inter-cell interference towards cell-edge users (CEUs) through multi-cell cooperation, where each collaborative base station serves both cell-center users (CCUs) and CEUs, including other cells' CEUs, under a power constraint. The present ICIC strategies cannot be directly applied to network MIMO because they were designed in absence of multi-cell coordination. In the presence of network MIMO, this paper investigates antenna orientations in ICIC and the method of power management. Results show that a proper antenna orientation can improve the cell-edge capacity and meantime lower the interference to CCUs. Capacity inconsistency between CCUs and CEUs is detrimental to mobile communications. Simulation results show that the proposed power management for ICIC in network MIMO systems can achieve a uniform data rate regardless users' position.

As a key component of lighting location system (LLS) for lightning warning, the atmospheric electric field measuring is required to have high accuracy. The Conventional methods of the existent electric field measurement meter can only detect the vertical component of the atmospheric electric field, which cannot acquire the realistic electric field in the thunderstorm. This paper proposed a three dimensional (3D) electric field system for atmospheric electric field measurement, which is capable of three orthogonal directions in X, Y, Z, measuring. By analyzing the relationship between the electric field and the relative permittivity of ground surface, the permittivity is calculated, and an efficiency 3D measurement model is derived. On this basis, a three-dimensional electric field sensor and a permittivity sensor are adopted to detect the spatial electric field. Moreover, the elevation and azimuth of the detected target are calculated, which reveal the location information of the target. Experimental results show that the proposed 3D electric field meter has satisfactory sensitivity to the three components of electric field. Additionally, several observation results in the fair and thunderstorm weather have been presented.

Lee jaema pointed out Zhugong as well as Zhang zhongjing and Hur joon to be the most worthy medical men in his book, Dong-eui-soo-sae-bo-won. Nevertheless, there has not been much research on Zhugong. This paper treats relations between contents in 'Huo-ren-shu' and 'Dong-eui-soo-sae-bo-won'. From this, we could find the reason why Lee jaema had estimated Zhugong so highly. The correlation between two books can be summarized as follows. First, both books emphasize biaoli and yinyang. Second, both books put their priority on bianbing over bianzheng. Third, Dong-eui-soo-sae-bo-won quoted the most medical cases and prescriptions from Huo-ren-shu after Shang-han-lun.

NDRG1 has been reported to exert pivotal roles in tumor progression and metastasis via Wnt/${\beta}$-catenin signaling pathway. However, little is known about the role of NDRG3 in hepatocarcinogenesis despite its classification in the same subfamily of NDRG1. The present study was aimed to characterize the expression pattern and understand the biological roles of NDRG3 in hepatocarcinogenesis, as a means to exploit its therapeutic potential. It was observed that NDRG3 was up-regulated in HCC tissues and higher NDRG3 expression was associated with significantly shorter overall survival. Furthermore, a lower level of NDRG3 exhibited marked positive correlation with metastasis-free survival. In vitro and in vivo experiments revealed that knock-down of NDRG3 inhibits HCC metastasis and angiogenesis. We further demonstrated that activation of WNT/${\beta}$-catenin signaling and enhanced CSC-like properties were responsible for NDRG3-mediated promoting effect on HCC. In conclusion, the principal findings demonstrated that high NDRG3 expression facilitates HCC metastasis via regulating the turnover of ${\beta}$-catenin, as well as provides a potential therapeutic target for future therapeutic interventions.

As China's infrastructure continues to grow, concrete filled steel tubular (CFST) structures are attracting increasing interest for use in engineering applications in earthquake prone regions owing to their high section modulus, high strength, and good seismic performance. However, in a corrosive environment, the seismic resistance of the CFST columns may be affected to a certain extent. This study attempts to investigate the mechanical behaviours of square CFST members under both a cyclic load and an acid rain attack. First, the tensile mechanical properties of steel plates with various corrosion rates were tested. Second, a total of 12 columns with different corrosion rates were subjected to a reversed cyclic load and tested. Third, comparisons between the test results and the predicted ultimate strength by using four existing codes were carried out. It was found that the corrosion leads to an evident decrease in yield strength, elastic modulus, and tensile strain capacity of steel plates, and also to a noticeable deterioration in the ultimate strength, ductility, and energy dissipation of the CFST members. A larger axial force ratio leads to a more significant resulting deterioration of the seismic behaviour of the columns. In addition, the losses of both thickness and yield strength of an outer steel tube caused by corrosion should be taken into account when predicting the ultimate strength of corroded CFST columns.
