This paper presents the tensile behavior of the stud connection between reinforced concrete(RC) and steel members. Hanger reinforcements are placed around the studs to transfer the tensile loads to the opposite side of the concrete member. Six specimens, of which variables were arrangement details of hanger reinforcements and studs. Tensile test results show that hanger reinforcements are effective to increase tensile strength and ductility. Test tensile strengths of specimens are compared with the nominal strengths by ACI codes(ACI 318-02, ACI 349-99) and PCI 1999.

Background: Homologous vein allografts are adequate for reconstruction of the middle hepatic vein (MHV) in living-donor liver transplantation (LDLT). However, supply is a matter of concern. To replace homologous vein allografts, polytetrafluoroethylene (PTFE) grafts were used. This study aimed to assess the long-term patency rates and complications of PTFE grafts used for MHV reconstruction of LDLT in a high-volume liver transplantation center. Methods: We analyzed the patency rates of PTFE-interposed MHV in 100 LDLT recipients and reviewed complications including PTFE graft migration. Results: The mean age was 53.5±5.4 years and male to female ratio was 73:27. Primary diagnoses were hepatitis B virus infection (n=71) and other (n=28). Mean model for endstage liver disease score was 16.2±8.3. V5 reconstruction was performed as either single anastomosis (n=85) or double anastomoses (n=14). No V5 reconstruction was required in one patient. V8 reconstruction was performed as single anastomosis, double anastomoses, and no reconstruction in 75, 0, and 25 patients, respectively. During a mean follow-up of 6 years, three recipients required early MHV stenting within 2 weeks. After 3 months, there were no episodes of congestion-associated infarct, regardless of MHV patency. Patency rates of PTFE-interposed MHV were 54.0%, 37.0%, and 37.0% at 1, 3, and 5 years, respectively. Unwanted PTFE graft migration occurred in two recipients, and the actual incidence was 2% at 5 years. Conclusions: PTFE grafts combined with small-artery patches demonstrated acceptably high short- and long-term patency rates. Since the risk of unwanted migration of PTFE graft is not negligibly low, lifelong surveillance is necessary to detect unexpected rare complications.

Background/Aims: Little is known about the efficacy of low-dose transdermal fentanyl (TDF) patches in opioid-naive patients with moderate-to-severe cancer pain. Methods: This study had an open-label, prospective design, and was conducted between April 2007 and February 2009 in seven tertiary cancer hospitals; 98 patients were enrolled. TDF was started using a low-dose formulation (12.5 μg/ hr), and the dose was adjusted according to the clinical situation of individual patients. Pain intensity, the TDF doses used, and adverse events (AEs) were monitored over 4 weeks. Data were analyzed using the intent-to-treat and per-protocol principles. Results: Of the 98 patients enrolled, 64 (65%) completed the study. The median pain intensity decreased from 6.0 to 3.0 (p < 0.001) at the follow-up visit. The efficacy of low-dose TDF on pain relief was consistent across groups separated according to gender (p < 0.001), age (p < 0.001), metastasis (p < 0.001), previous treatment (p < 0.001), and baseline pain intensity (p < 0.001). The decrease in pain intensity was significantly greater in the severe group compared with the moderate group (mean ± SD, 5.10 ± 2.48 vs. 2.48 ± 1.56; p < 0.001). TDF dose (27.8 μg/ hr vs. 24.8 μg/hr, p = 0.423) and the mean treatment time (7.5 days vs. 7.9 days, p = 0.740) required for pain control were not different between the two pain-intensity groups. Patients had AEs of only mild or moderate intensity; among these, nausea (38%) was the most common, followed by vomiting (22%) and somnolence (22%). Conclusions: Low-dose TDF was an effective treatment for patients with cancer pain of moderate-to-severe intensity. Further randomized trials assessing the ef- ficacy of TDF for severe pain and/or optimal starting doses are warranted.

<P>An error-based control method is proposed for a single-inductor multiple-output (SIMO) converter that maintains high efficiency under various load conditions. A peak efficiency of 88.7% was achieved with one output <TEX>$({\rm I}_{{\rm O}1})$</TEX> of 5 mA, while the other outputs are at 432 mA. A hybrid topology composed of a switching converter and a linear regulator is also presented for fast load transient response. The proposed SIMO buck converter was fabricated with a 1P4M 0.35 <TEX>$\mu$</TEX>m BCD process and has 10 independently regulated outputs. The measured load transient waveform shows cross regulation of 0.1 mV/mA and a load transient of 0.17 mV/mA. This was achieved under load transient conditions for one output <TEX>$({\rm I}_{{\rm O}9})$</TEX> in between 1 mA and 100 mA with the other outputs at 422 mA.</P>
