  • In the assessment of patency of a small vessel anastomosis, micro-arteriography using dental X-ray and film was used as a method of testing the patency of arterial anastomoses in the rat. Micro-arteriography could lead to an objective evaluation of the patency in End-to-End and End-to Side anastomoses. The method used in this study is easily accessible for Oral and Maxillo-facial surgeon to practice the microvascular anastomosis, and requires materials available in every dental clinic.

  • We define some asset models which are useful for portfolio construction in various terms of time. Our asset models are geometric jump-diffusions defined by the solutions of stochastic differential equations which are decomposed by various terms of time basically. We also can study pricing and hedging strategy of options in our models roughly.

  • As multiple functions arc required in a robot controller, RTOS(Real Time Operating System) should be adopted to manage complex situations, such as choosing most urgent task among competing ones. In this paper, we implemented RTAI(Real Time Application Interface) based robot controller for wafer handling robots including graphic simulator. We showed how multiple tasks are organized and also explained in detail about task priorities and execution periods. Finally, we presented simulation results.
