  • In this paper, the architecture of a dataflow logic solving processor for programmable logic controller is proposed. As the proposed DFLSP(dataflow logic solving processor) is designed based on the dataflow architecture, it has inherently concurrent processing and data synchronization capabilities. And also, it has dynamic load balancing capabilites which increases the utilization of the whole system that can he hardly implemented in other multiprocessor system. The re-matching unit gets rid of unnecessary matching cycles in LSU, which increases the performance of LSU and allows the multiple input multiple output operations.

  • A desirability function approach to a multiresponse problem is proposed considering process parameter fluctuation which may amplify the variance of response. It is called POE (propagation of error), which is defined as the standard deviation of the transmitted variability in the response as a function of process parameters. In order to obtain more robust process parameter setting, a new desirability function is proposed by considering POE as well as distance-to-target of response and response variance. The proposed method is illustrated using a rubber product case in Ribeiro et al. (2000).

  • The change of membrane fluidity in rockfish (Sebastes schlegeli) phagocytes during respiratory burst was investigated. Fluorescence polarization (FP) was used as a measure of membrane fluidity, and 1-(4-trimethylaminophenyl)-6-phenyl-1 .3 ,5-hexatriene (TMA.-DPH) was used us a fluorescent probe. The significantly higher FP values in phagocytes stimulated With zymosan or phurbol myristate acetate (PMA) than unstimulated control phagocytes suggests that membrane fluidity of phagocytcs is decreased during the respiratory burst. The faster decrease of FP value in PMA stimulated phagocytes than in zymosan sumulated phagocytes may be due to bypass of the receptor-mediated stages of functional modulation. which is needed in zymosan stimulated phagocytes.

  • A loss function approach to a multiresponse problem is considered, when process parameters are regarded as random variables. The variation of each response may be amplified through so called propagation of error (POE), which is defined as the standard deviation of the transmitted variability in the response as a function of process parameters. The forms of POE for each response and for a pair of responses are proposed and they are reflected in our loss function approach to determine the optimal condition. The proposed method is illustrated using a polymer case. The result is compared with the case where parameter fluctuation is not considered.

  • Occasionally, extensor hallucis longus tendon (EHL) ruptures becames open by laceration and spontaneous rupture of EHL that has previous story of diabetes mellitus, steroid injection, systemic steroid administration, operation and rheumatoid arthritis. But, closed traumatic EHL ruptures are reported rarely. Especially, we diagnosed the closed EHL ruptures in TaeKwonDo players. We reported the 2 patients, differently treated end to end anastomosis and EHL transfer, had the course and treatment methods. Be care the prognosis can be altered according to the treatment time and method.

  • This paper presents the design and analysis of gate-recessed AlGaN/GaN Fin-type Field-Effect Transistor (FinFET). The three-dimensional (3-D) technology computer-aided design (TCAD) simulations were performed to analyze the direct-current (DC) and radio-frequency (RF) characteristics for AlGaN/GaN FinFETs. The fin width ($W_{fin}$) and the height of GaN layer ($H_{GaN}$) are the design parameters used to improve the electrical performances of gate-recessed AlGaN/GaN FinFET.
