  • This study was carried out to demonstrate how realistic any action that causes the selection criteria for new members to join the decisions of the general public about the growing recreational sport of golf to the present day. Looking at the results of in-depth interviews, "time out through direct participation "" become more and more expensive equipment "," varied program "," located near "," are items of personal development and interpersonal relationships "was found to have a significant impact on the public choice of leisure sports. It was with the greatest response in the dual to "become more and more expensive equipment," "self-development and personal relationships." These results exigent there in living the contemporary social phenomena that can not ignore the economic aspects of choosing a leisure sport and personal development and interpersonal relationships in organizations improve social promotion and sales, a key role in providing opportunities for upward mobility suggests that the passage is.

  • In this paper, a new set of structural and sacrificial material that is diamond like carbon (DLC)/photoresist for high performance piezoelectric RF-MEMS switches which are actuated in d33 mode is suggested. To avoid curing problem of photoresist sacrificial layer, DLC structure layer is deposited at room temperature by radio frequency plasma enhanced chemical vapor deposition (RF-PECVD) method. And lead zirconate titanate (PZT) piezoelectric layer is deposited on structure layer directly at room temperature by rf magnetron sputtering system and crystallized by rapid thermal annealing (RTA) equipment. Particular attention is paid to the annealing of PZT film in order to crystallize into perovskite and the variation of mechanical properties of DLC layer as a function of annealing temperature. The DLC layer shows good performance for structure layer in aspect to Young's modulus and hardness. The fabrication becomes much simpler and cheaper with use of a photoresist.
