Human torso plays an important role of rigid connection during exercise. It can effectively converge and integrate the power of the body parts, which plays a strong leverage for the athletes of the coordinated development of motor skills. As far as basketball is concerned, strong core strength can be more stable, and cab fix basketball athlete＇ s body posture, integrating the body organically with the development of all aspects, and making the upper and lower extremities more coordinated with each other, helping improve athletic level.展开更多

It is conducted completely under water by divers and unique welding technology is required in the special operation environment. The operating levels of the divers are the key factor to acquire high quality welded joints. In this paper, an underwater wet welding experimental and divers training system is developed to serve divers training and conducting welding experiments. The system consists of life support system, signals real-time monitoring system and communicating system, etc. An underwater butt welding experiment based on welding electrodes is conducted, and the system works well. It proves that the system can guarantee divers welding safely and successfully and high quality weld seam is expected to be acquired.展开更多

The purpose of this study was to examine the effects of plyometric and explosive speed training （PLYO） on recreational marathoners. METHODS： Twenty-two subjects （ages 18-23）, were randomized to either PLYO or core training （CORE） for a weekly session performed for 12 weeks, in addition to marathon training. Sprint, jump, and distance running performance variables were measured pre- and post-intervention. RESULTS： In the sprint tests, the PLYO group improved in both the 200-m run （P ≤ 0.001） and 60-m run （P = 0.004）, and trended toward improvement in the 30-m fly （P = 0.051）. The difference from CORE was significant only in the 200-m （P = 0.002）. The CORE group did not change in any of the sprint or jump variables. The PLYO group was significantly different from the CORE group in the standing long jump （P = 0.024）. There were no differences between groups in distance running performance. Both improved in 2-mile （3.219-km） time trial （p 〈 0.001）, VO2MAX （P = 0.026 for CORE; P = 0.002 for PLYO）, and running economy （P = 0.01）. CONCLUSION： Weekly PLYO training improves sprint speed and maintains jumping ability in recreational marathoners, but does not augment improvements in distance running performance.展开更多

A large number of sandstone computedtomography (CT) images are used as training input for a fully convolutional neural networkmodel. This model is used to reconstruct the three-dimensional (3D) digital core of Bereasandstone based on a small number of CT images. The Hamming distance together with theMinkowski functions for porosity, average volume specifi c surface area, average curvature,and connectivity of both the real core and the digital reconstruction are used to evaluate theaccuracy of the proposed method. The results show that the reconstruction achieved relativeerrors of 6.26%, 1.40%, 6.06%, and 4.91% for the four Minkowski functions and a Hammingdistance of 0.04479. This demonstrates that the proposed method can not only reconstructthe physical properties of real sandstone but can also restore the real characteristics of poredistribution in sandstone, is the ability to which is a new way to characterize the internalmicrostructure of rocks.展开更多

The findings can serve as references for planning core courses of employee training and labor employment. Based on the research purposes, this study adopted revised DACUM, conducted literature review, and applied a questionnaire survey. The subjects were the members of SMEs Honor Instructor Association of Ministry of Economic Affairs, Taiwan, and the Society of Management Science. Random sampling was used, with the number of employees as the units. The valid return rate was 24.2%. After testing goodness of fit of K-S single samples, this study found that a corporate management work force should have 11 items of core competencies, and 35 items of secondary competency.展开更多
