Thin films of vanadium oxide(VO_(x)) have been deposited by RF magnetron sputtering from V₂O_(5) target in gas mixture of argon and oxygen. The oxygen/(oxygen+argon) partial pressure ratio of 0% and 8% is adopted. Crystal structure and optical properties of films sputter-deposited under different oxygen gas pressures and in situ annealed in vacuum at 400℃ for 1h and 4h are characterized through XRD, XPS, RBS, FTIR, and optical absorption measurements. The films as-deposited are amorphous, but 0%O₂ films annealed for time longer than 4h and 8%O₂ films annealed for time longer than 1h are polycrystalline. I-v characteristics were distinguished between linear and nonlinear region. In the low field region the conduction is due to Schottky emission, while at high fields it changes to Fowler-Nordheim tunneling type conduction. The conductivity measurements have shown an Arrhenius dependence of the conductivity on the temperature.

This study was aimed at clarifying the effect of a dietary ragime designed to enhance the body's glycogen-storaging ability on the record of long-distance runners. The subjects employed were a total of 24 male college long-distance runners aged between 19 and 21 years. As a preliminary experiment, 8 ml/㎏ BW of 20% glucose was administered and blood levels of glucose, insulin and lactate were observed. The dietary regime consisted of low-carbohydrate diet with heavey exercise for 3 days followed by high-carbohydrate diet with light exercise for 3 days. On the day after the last day of the dietary regime, 20 ㎞-running was performed and blood levels of glucose, insulin and lactate, hematocrit and body weight were measured. The measured parameters and the records were compared with those measured during 20 ㎞-running performed before the dietary regime. The results obtained are summarized as follows. After the administration of 20% glucose, blood glucose level was doubled in 30 min. Insulin was increased by 6.5 times in 60 min and was sharply decreased in 120 min but was still higher than the resting level. Blood levels of glucos(x) and insulin(y) revealed a high correlation and the regression equation was y=-16.90+0.294x. Blood lactate was somewhat increased. After 20 ㎞-running, the blood glucose, insulin and lactate were all increased. Compared with those measured before dietary regime, blood glucose and lactate levels measured after the regime were higher, while the insulin was lower. The body weight was reduced and the hematocrit was increased by the dietary regime. The record was improved by 2 min 3 sec. From the above results, it can be concluded that high-carbohydrate diet such as glucose solution is necessary in restoring the depleted blood glucose level during exercise, that meals should be taken at least 2∼3 hours before long-distance running to get the increased plasma insulin level restored and that improved endurance can be obtained by accumulating body glycogen through dietary regime.

Multiple Target Angle-tracking Using Angular Innovations Extracted from Noise Subspace

Hwang Soo Bok,Kim Jin Seok,Kim Hyun Sik,Nam Ki Gon The Acoustical Society of Korea 2005 韓國音響學會誌 Vol.24 No.e1

Ryu et al. proposed a multiple target angle-tracking algorithm without a data association problem using angular innovations. This algorithm, however, needs the computational loads in proportion to the square number of sensors regardless of the number of targets, because it uses a nonlinear equation between the signal subspace and angular innovation. In this Paper, we proposed an efficient algorithm for the multiple target angle-tracking using angular innovations. The proposed algorithm extracts the angular innovations from noise subspace. Also, it is demonstrated by computer simulations dealing with the tracking of crossing targets. The simulation results show that the computational loads of the proposed algorithm are $80\%$ and $60\%$ of those of Ryu's algorithm for 3 targets and 6 targets without degrading the performance of the target tracking.

The aim of present study was to evaluate the effects of link height and dental cements on the retention force between titanium link and zirconia abutment in the Ti-Zr bicomponent abutment system. Three different height (2.0, 2.5, and 3.0 mm with 0o taper) of titanium links (MonoDent, Korea) were machined and pertinent zirconia abutments (Acucera, Korea) were fabricated with CAD/CAM. One hundred thirty five titanium links and zirconia abutments were prepared. Zirconia abutments were cemented on their respective titanium links with three different types of dental cements, such as zinc phosphate (Fleck’s), resin-modified glass ionomer (RMGI, RelyX Luting 2), self-adhesive resin cement (RelyX U200). Specimens were stored in deionized water (37℃) for 24 hours until testing. Pull-off test was performed using a universal testing machine (Instron 4466, USA) with a crosshead speed of 1 mm/min. Fifteen specimens were tested at each experimental group. The data were analyzed using t-test and Newman-Keuls multiple comparisons test (p=0.05). RMGI showed the lowest retention force (p<0.05) and ZPC showed similar retention force with resin cement (p>0.05) regardless of link heights. For ZPC groups and self-adhesive resin cement groups, 3.0 mm height showed significantly higher retention force than both 2.5 mm and 2.0 mm groups which were not significantly different (p>0.05) For RMGI groups, the retention force increased significantly with increasing of link height (p<0.05). To obtain the proper retention in clinical situation, height of titanium link should be no less than 3.0 mm.

Recently, as new technologies such as SAN and NAS come into wide use to deal with a large amount of data, an efficient backup software for SAN and NAS is very required. In this paper, we design and implement a backup software for SAN that fully supports NDMP. The NDMP is an open standard protocol for network-based backup. The proposed backup software has various unique features such as SAN based lan-free backup, automatic and manual backup, on-line backup by using snap shot, file-system, raw-device, database backup and so on. The proposed backup software also can be configured as a backup center that uses SAN as a backup media.

Tetraspanin-2 promotes glucotoxic apoptosis by regulating the JNK/β-catenin signaling pathway in human pancreatic β cells

<P>Diabetes mellitus is a complex and heterogeneous disease, which has β-cell dysfunction at its core. Glucotoxicity affects pancreatic islets, causing β-cell apoptosis. However, the role of JNK/β-catenin signaling in glucotoxic β-cell apoptosis is not well understood. Recently, we identified tetraspanin-2 (TSPAN2) protein as a proapoptotic β-cell factor induced by glucose, suggesting that TSPAN2 might contribute to pancreatic β-cell glucotoxicity. To investigate the effects of glucose concentration on TSPAN2 expression and apoptosis, we used reverted immortalized RNAKT-15 human pancreatic β cells. High TSPAN2 levels up-regulated phosphorylated (p) JNK and induced apoptosis. p-JNK enhanced the phosphorylation of β-catenin and Dickkopf-1 (Dkk1). Dkk1 knockdown by small interfering (si)RNA up-regulated nuclear β-catenin, suggesting that it is a JNK/β-catenin-dependent pathway. siRNA-mediated TSPAN2 depletion in RNAKT-15 cells increased nuclear β-catenin. This decreased BCL2-associated X protein (Bax) activation, leading to marked protection against high glucose–induced apoptosis. Bax subfamily proteins induced apoptosis through caspase-3. Thus, TSPAN2 might have induced Bax translocation and caspase-3 activation in pancreatic β cells, thereby promoting the apoptosis of RNAKT-15 cells by regulating the JNK/β-catenin pathway in response to high glucose concentrations. Targeting TSPAN2 could be a potential therapeutic strategy to treat glucose toxicity-induced β-cell failure.—Hwang, I.-H., Park, J., Kim, J. M., Kim, S. I., Choi, J.-S., Lee, K.-B., Yun, S. H., Lee, M.-G., Park, S. J., Jang, I.-S. Tetraspanin-2 promotes glucotoxic apoptosis by regulating the JNK/β-catenin signaling pathway in human pancreatic β cells.</P>
