<P><B>Objective: </B> To compare the mid‐term oncological outcome of laparoscopic radical cystectomy (LRC) with those of open radical cystectomy (ORC).</P><P><B>Methods: </B> From June 2003 to February 2008, 36 LRCs were carried out at our institute for the treatment of bladder cancer. Clinical and oncological data were retrospectively analyzed. A match‐pair comparison with an historical series of 34 patients who were submitted to ORC between 1996 and 2003 was carried out.</P><P><B>Results: </B> Median follow‐up of the LRC group was 21 months (3–56 months). Pathological stage or grade was similar in the two groups. There was no significant difference between the LRC and ORC groups in terms of 3‐year overall (64.2% <I>vs</I> 72.6%, respectively; <I>P</I> = 0.682), cancer‐specific (73.0% <I>vs</I> 75.3%, respectively; <I>P</I> = 0.951), and recurrence‐free survival (70.5% <I>vs</I> 72.5%, respectively; <I>P</I> = 0.715) rates. In a subgroup analysis according to stage, there was also no significant difference in the 3‐year disease‐specific survival after LRC or ORC for organ‐confined (pT1 and pT2; 85.7% <I>vs</I> 83.9%, respectively; <I>P</I> = 0.256) or extravesical disease (pT3 and pT4; 73.3% <I>vs</I> 63.8%, respectively; <I>P</I> = 0.825).</P><P><B>Conclusion: </B> These findings suggest that LRC provides mid‐term oncological outcomes similar to those of ORC in the management of bladder cancer.</P>

Technology commercialization capability plays such a critical role in successfully converting the performances from firms R & D activities into their actual revenues that a lot of studies have paid their special attention to the antecedents to firms technology commercialization capability so far, forming a research stream on the antecedents. The goal of this study is to widen the research stream on the antecedents to SMEs technology commercialization capability. By constructing the research model for the mediating impacts of the product interior design and the testing and inspection capability and analyzing the 2,000 data from the SMEs in the Republic of Korea, this research provides the following implications. SMEs product interior design capability fully mediates the positive effect of the external technology collaboration network diversity on their technology commercialization capability and their testing and inspection capability partially mediates it. Futhermore, SMEs product interior design capability and testing and inspection capability jointly and fully mediate the positive effect of the external technology collaboration network diversity on the technology commercialization capability.

The influence of 248-nm KrF excimer laser annealing (ELA) with energy density between 0 and 400 mJ/cm2 on the electrical behavior of indium gallium zinc oxide (InGaZnO) thin-film transistors (TFTs) is investigated. The experimental results show that the saturation mobility and subthreshold swing are improved from 12.4 cm2/Vs and 100 mV/dec without ELA to 17.8 cm2/Vs and 75 mV/dec, respectively, by applying a 300 mJ/cm2 laser pulse after the source/drain deposition, while maintaining an almost unchanged turn-off voltage. Such improvements are attributed to the increase in the oxygen vacancies and reduction in the bulk traps in the InGaZnO channel.

New technology development capability plays a key role in making small- and medium-sized enterprises (SMEs) increase their innovation performance, such as in product or process innovation. To examine the influencing factors of SMEs' new technology development capability, this study empirically analyzes the mediating effects of SMEs' process design capability and product interior design capability on the positive association between their external information network diversity and new technology development capability. This study performs the ordinary least squares regression on a sample of 2,000 South Korean SMEs. Results reveal that SMEs' process design capability fully mediates, and product interior design capability partially mediates the positive association between the external information network diversity and new technology development capability.
Magnetic Resonance Image Processing Based on FPGAs

Magnetic resonance imaging (MRI) plays an important role for medical imaging technology in brain anatomical studies. Many automatic algorithms have been proposed for analyzing magnetic resonance imaging data sets. With the increasingly large data sets being used in mapping, there are some limitations of the manual algorithms, such as long computation time and issues regarding reproducibility. There has been a significant rise in the need for accelerating these algorithms. This paper handled the partial volume estimation (PVE), a brain tissue classification algorithm for MRI, on a field-programmable gate array (FPGA) as high performance reconfigurable computer using the Mitrion-C high-level language (HLL). FPGAs are very flexible and could achieve significant performance improvement by exploiting parallelism in processing. We used several simulated and real human brain MRI to evaluate the performance improvement of the proposed algorithm. The performance of probability density and prior information estimation implementation based on FPGAs achieved the overall speedup.
