Shanghai Tower is a composite structure building with a height of 632 m. In order to verify the structural properties and behaviors in construction and operation, a structural health monitoring project was conducted by Tongji University. The monitoring system includes sensor system, data acquisition system and a monitoring software system. Focusing on the health monitoring in construction, this paper introduced the monitoring parameters in construction, the data acquisition strategy and an integration structural health monitoring (SHM) software. The integration software - Structural Monitoring/ Analysis/ Evaluation System (SMAE) is designed based on integration and modular design idea, which includes on-line data acquisition, finite elements and dynamic property analysis functions. With the integration and modular design idea, this SHM system can realize the data exchange and results comparison from on-site monitoring and FEM effectively. The analysis of the monitoring data collected during the process of construction shows that the system works stably, realize data acquirement and analysis effectively, and also provides measured basis for understanding the structural state of the construction. Meanwhile, references are provided for the future automates construction monitoring and implementation of high-rise building structures.

Objective : The purpose of this study was to report the improvement in a patient with edema treated by herb medication based on Shanghanlun provisions. Methods : According to 'A disease pattern identification diagnostic system based on Shanghanlun provisions (DPIDS)', a patient was diagnosed with Taeyang-byung, no. 46 provision and was administered with Mahwang-tang herbal medication for 30 days. The Numeric rating scale (NRS) was used to estimate the response. Results : The NRS score changed from 10 to 1 and the edema disappeared by 46th provision of Mahwang-tang selected according to Shanghanlun provisions. Conclusions : This case report suggests that the two words in the 46th provision of Shanghanlun, '陽氣重, 無汗' (Yang qi heavy, Absence of sweating) indicate a close relationship between photosensitivity and absence of sweating, thereby affecting edema in this case.

XRCC1 genetic polymorphisms could be associated with increased risk of various cancer, including hepatocellular carcinoma (HCC), the fifth most common cancer. We here conducted a study to explore the role of selective SNPs of the XRCC1 and XPD genes in the prognosis of HCC. A total of 231 cases were collected, and genotyping of XRCC1 Arg194Trp, XRCC1 Arg399Gln, XPD Lys751Gln and XPD Asp312Asn was performed by duplex polymerase-chain-reaction with the confronting-two-pair primer method. Our findings indicated XRCC1 399Gln/Gln genotype was associated with a significant difference in the median survival time compared with patients carrying Arg/Trp and Arg/Arg genotypes, and individuals with XPD 751 Gln/ Gln genotype had a significantly greater survival time than patients carrying Lys/Lys and Lys/Gln genotypes. The Cox's regression analysis showed individuals carrying XRCC1 399Trp/Trp genotype had 0.55 fold risk of death from HCC than Arg/Arg genotype. Similarly, XPD 751Gln/Gln had a strong decreasein comparison to XPD Lys/Lys carriers with an HR of 0.34. These results suggest that polymorphisms in XRCC1 and XPD may have functional significance in the prognosis of HCC.

For CMOS technology of 65 nm and beyond, the gate leakage current can not be negligible anymore. In this paper, the impact of the gate leakage current in ring voltage-controlled oscillator (VCO) on phase-locked loop (PLL) is analyzed and modeled. A voltage -to-voltage (V-to-V) circuit is proposed to reduce the voltage ripple on $V_{ctrl}$ induced by the gate leakage current. The side effects induced by the V-to-V circuit are described and optimized either. The PLL design is based on a standard 65 nm CMOS technology with a 1.8 V power supply. Simulation results show that 97 % ripple voltage is smoothed at 216 MHz output frequency. The RMS and peak-to-peak jitter are 3 ps and 14.8 ps, respectively.

Pi(Spleen, 脾) corresponds to central earth and is called as the basis of acquired essence as it has the function of transforting and transforming the nutrients, keeping the blood circulating, and nourishing the muscle and limbs. Recently many studies to research the nature and deficiency of Pi are actively carried out. Especially functional deficiency of Pi(脾虛證) which occupies 60 to 70% or 88% in miscell aneous disease is divided into deficiency of Qi(脾氣虛), Yang(脾陽許), and Yin(脾陰虛), and tought to be positive when three or more such symptoms as anorexia, abdominal distension, loose bowels, pale face and weakness are present. Investigating the resent studies on the nature of the deficiency of Pi shows that Pi has the function of digestive system and also should be considered as functional unit of mult system related immune, metabolic, hematic, muscular, rnddocrine and nervus system. Various experiments as ptyaline activity test and xylose absorption test are used as an indication to deficiency of Pi and would be helpful to understand its nature. As deficiency of Pi appears in many disease and has various manifestations, further studies to diagnose the symptom of Pi using various experiments and oriental medical diagnostic method should be ensued.

The drainage problem in bifurcations causes pecuniary losses when hydropower stations are undergoing periodic overhaul. A new design philosophy for Y-typed bifurcations that are flat-bottomed is proposed. The bottoms of all pipe sections are located at the same level, making drainage due to gravity possible and shortening the draining time. All fundamental curves were determined, and contrastive analysis with a crescent-rib reinforced bifurcation in an actual project was conducted. Feasibility demonstrations were researched including structural characteristics based on finite element modeling and hydraulic characteristics based on computational fluid dynamics. The new bifurcation provided a well-balanced shape and reasonable stress state. It did not worsen the flow characteristics, and the head loss was considered acceptable. The proposed Y-typed bifurcation was shown to be suitable for pumped storage power stations.

A series of Brazilian tests under diameter compression for disc specimens was carried out to investigate the strength and failure behavior by using acoustic emission (AE) and photography monitoring technique. On the basis of experimental results, load-displacement curves, AE counts, real-time crack evolution process, failure modes and strength property of granite specimens containing two pre-existing holes were analyzed in detail. Two typical types of load-displacement curves are identified, i.e., sudden instability (type I) and progressive failure (type II). In accordance with the two types of load-displacement curves, the AE events also have different responses. The present experiments on disc specimens containing two pre-existing holes under Brazilian test reveal four distinct failure modes, including diametrical splitting failure mode (mode I), one crack coalescence failure mode (mode II), two crack coalescences failure mode (mode III) and no crack coalescence failure mode (mode IV). Compared with intact granite specimen, the disc specimen containing two holes fails with lower strength, which is closely related to the bridge angle. The failure strength of pre-holed specimen first decreases and then increases with the bridge angle. Finally, a preliminary interpretation was proposed to explain the strength evolution law of granite specimen containing two holes based on the microscopic observation of fracture plane.

This thesis is a literature study about oriental medicine on insomnia. Insomnia is defined as deficiency of sleeping caused by disability of the period of sleeping and lack of recovery of original vital energy. The main causes of insomnia are the dysfunction of the stomach, the wet phlegm, the deficiency of vigor, Qi of the heart, the lack of Yin, the defect of gall bladder or the excessive anxiety and so on, in the oriental medicine. Insomnia patients, in the oriental medicine, is treated by both removing food stagnancy and regulating the vital function of stomach, controlling the wet phlegm, both nourishing the heart and reinforcing the vital energy, providing vital essence to subdue the fire, tonifing both the heart and spleen or warming the gall bladder, etc. The number of insomnia patients shows a tendency to increase by the stresses of modern society and stimulus caused form the unbalance of Yin and Yang. Medical treatments for insomnia are studied, also, in diverse fields according to the increasing in number of insomnia patients. The literature study about the causes and medical treatments of insomnia is useful for the access to effective oriental medical treatments for insomnia.
