The Current of Continuing Professional Development for Product Designers

Product Designers are required some skills and knowledge in the product development. Based on my professional career, I presumed three skills, they are, Technical skills, Conceptual skills and Human skills. In this study, I interviewed some Product Designers to make sure what skills are needed in the product development process. It emerged that Product Designers are expected to improve their Conceptual and Human skills besides Technical skills for playing a part at the upper and lower stage of the process to create the new value in the product development.departmental bulletin pape

Light Transport Refocusing for Unknown Scattering Medium

In this paper we propose a new light transport refocusing method for depth estimation as well as for investigation inside scattering media with unknown scattering properties. Propagated visible light rays through scattering media are utilized in our proposed refocusing method. We use 2D light source to illuminate the scattering media and 2D image sensor for capturing transported rays. The proposed method that uses 4D light transport can clearly visualize shallow depth, as well as deep depth plane of the medium. We apply our light transport refocusing method for depth estimation using conventional depth-from-focus method and for clear visualization by descattering the light rays passing through the medium. To evaluate the effectiveness we have done experiments using acrylic and milk-water type scattering medium in various optical and geometrical conditions. Finally, we show up the results of depth estimation and clear visualization, as well as with numeric evaluation.conference pape

<Original Article> Subcutaneous versus Epidural Administration of Fentanyl for Postoperative Analgesia

Contenuous subcutaneous infusion of opioids may be a preferable alternative for postoperatlve pain relief in patients without an epidural catheter. Thls study compared the efficacy of subcutaneous fentanyl with that of epidural fentanyl for management of postoperative pain. Twenty patients scheduled for gynecological surgery were randomly assigned to receive subcutaneous (SQ group) or epidura1 (EP group) fentanyl over 24 hr via the allocated route. About 30 minutes before the end of surgery, patients in the SQ group received an initial bolus of fentanyl (100 μg) subcutaneously followed by an infusion of 33 μg/hr for 24 hr by the subcutaneous route using a disposable infusion device (DIB catheter, DIB International Inc.,Japan). While patients in the EP group received an initial dose of fentanyl (50 μg) through an epidural catheter followed by an infusion rate of 17 μg/hr for 24 hr using the same device. There was no significant difference in the visual analogue score (VAS) at 24 hr between the two groups, though VAS (4.3 ±1.8) in the SQ group was significantly higher than that in the EP group (2.1±1.5) at 3 hr after surgery. No patients had severe complications. We conclude that continuous subcutaneous infusion of fentanyl seems to provide simple and relatively effective analgesia after surgery, though epidural injection provides better pain relief.journal articl

Transmit Permission Control on Spread ALOHA Packets in LEO Satellite Systems

A transmit permission control method for improving the throughput characteristics of a low earth orbit (LEO) satellite communication system employing spread-slotted ALOHA multiple-access scheme is proposed. Both nonfading and fading satellite links are considered. The basic idea of the proposed scheme is to decrease the level of interference at each satellite and, hence, to increase the probability of packet success, by prohibiting the packet transmission from the users with relatively high propagation loss to their connecting satellites. It is shown that the method has the ability to improve the throughput performance in heavy traffic loads and the peak value of the throughput, significantly. It is also shown that the average delay performance of the system employing the proposed scheme is superior to that of the conventional system at heavy loads.journal articl
