Methods: A total of 60 patients with CFS-related sleep disorders were randomized into a control group and an observation group, with 30 cases in each group. The control group was treated with oral administration of fluoxetine hydrochloride capsule. The observation group was treated with moving cupping on the back, once every other day. The efficacy was observed after 4 weeks of treatment. The fatigue scale-14 (FS-14) and Pittsburgh sleep quality index (PSQI) were assessed before and after the treatment to evaluate the clinical efficacy. Results: The total effective rate was 93.3% in the observation group, and 73.3% in the control group. The difference between the two groups was statistically significant (P<0.05). After treatment, the improvement of physical fatigue value, mental fatigue value, and the total score of FS-14 in the observation group were statistically different from those in the control group (all P<0.05). The scores of subjective sleep quality, sleep latency, habitual sleep efficiency, use of sleeping medication, daytime dysfunction of PSQI and the total score in the observation group were improved more significantly than those in the control group (all P<0.05). Conclusion: Moving cupping on the back can significantly improve sleep disorders in CFS patients, and it has a better curative effect than oral fluoxetine hydrochloride capsules.展开更多

Dopplerlet matching pursuit are used to estimate range and speed. The line spectrums of moving vessel radiated-noises show some time-frequency features. The features of line spectrum reflect the variation of moving state of the vessel. The computer simulation shows the method is practicable and effective. Moreover, the method is applied to estimate the range and the speed of a real underwater signal and the results agree with the data of the experiment on the sea.展开更多

Here, the effect of the rolling massage frequency to the blood flow in the blood vessels under the rolling massage manipulation is studied by the lattice Boltzmann simulation. The simulation results show that when the frequency is smaller than or comparable to the pulsatile frequency of the blood flow, the effect on the blood flux by the rolling massage is small. 011 the contrast, if the frequency is twice or more times of the pulsatile frequency of the blood flow, the blood flux is greatly enhanced and increases linearly with respect to the frequency. Similar behavior has also been observed on the shear stress on the blood vessel walls. The result is helpful for understanding that the rolling massage has the function of promoting the blood circulation and removing the blood stasis.展开更多

An axisymmetrical nonlinear model and an arbitrary Lagrangian-Eulerian finite element method (ALE-FEM) with rezoning algorithm were introduced to study the viscous flow through an axisymmetrical rigid tube with axially moving stenosis to simulate the rolling manipulation. Flow rate and wall shear stress were obtained by solving complete Navier-Stokes equations numerically. The numerical results show that the stenosis moving frequency, namely the frequency of rolling manipulation, has great effect on the disturbance of flow and the wall shear stress. The stenosis coefficient, which characterizes the severity of the stenosis, another adjustable parameter in rolling manipulation, also shows the significant effect on flow rate and wall shear stress. These numerical results may provide some data that can be taken into consideration when massage is used in clinic.展开更多

Some of the previous studies indicated that the performance of ship operation would be affected by variables of vessel calls, such as ship size, container loaded and container discharged would affect the handling rate of ship operation, but it didn’t clarify on the degree of relationship and lack of variable container shifted/restowed. Therefore, this study would further study on the softcoming, to analyse the relationship between variables of vessel calls with berth turnaround time, that affected the ship operation’s performance. Extensive observation and survey activities were conducted at Malaysian’s Port and the collected data was based on ship operation delay parameters;like berth turnaround time, total move, total discharge, total load, shift/restow, and length overall of vessels. The initial result showed that total move, total discharge and total load had high correlation with berth turnaround time. The r-value of total move, total discharge and total load are 0.877, 0.716 and 0.804 respectively. Therefore, this study concluded that the berth turnaround time is highly affected by total move, total discharge and total load. Consequently, the research output would be as a decision making tool to port planner.展开更多
