Improvement in Thermal Stability of Nickel Silicides Using NiN<sub><i>x</i></sub> Films
Kim, Sun Il,Lee, Seung Ryul,Ahn, Kyung Min,Ahn, Byung Tae The Electrochemical Society 2010 Journal of the Electrochemical Society Vol.157 No.3
<P>A nickel nitride [Formula] film is proposed as a Ni source for silicidation to improve the thermal stability of a nickel silicide (NiSi) layer. The stability of the film was investigated for temperatures above [Formula]. The nitrogen content in the [Formula] film could be controlled by varying the [Formula] flow ratio during deposition. When the [Formula] film was annealed, the formation temperature of the NiSi layer was higher than that of layers formed from the pure Ni film due to the retardation of Ni diffusion into the Si substrate by an amorphous Si–N layer at the nickel nitride/Si interface. After an additional annealing above [Formula], the sheet resistances [Formula] of the NiSi layers formed from the [Formula] film remained low, while the [Formula] of those formed from the pure Ni film increased sharply. Apparently, the suppression of the agglomeration of the NiSi layer by the utilization of the [Formula] film can improve its thermal stability.</P>

Recently, the city is growing up rapidly as the population increases. The commercial and residential area of the city are sharply increased. As a result, the city appearing climate change present situation from artificial thermal and air pollution of material. Therefore, to analyze the phenomena of climate change in cities, it is needed that we should carry out research on the characteristics of 'flow and thermal environment' of small and medium size cities. Continuous measurement, instantaneous measurement carry out for more analysis thermal environment by climate change of Asan city. The continuous measurement selected the city center commercial areas and the residential areas and it measured a temperature, a humidity and a wind speed.(2008.08.05~2008.08.08) The instantaneous measurement selected crossroad, green space, water-space for measure time zone. (2008.08.07) We analyzed the data of continuation measurement and instantaneous measurement and the data of the same day at Korea meteorological observation station near by that city.

<P><B>Abstract</B></P> <P><B>Background</B></P> <P>We investigated whether the microsatellite instability (MSI) status affects the survival outcomes in patients with stage II/III rectal cancer who have undergone an upfront curative resection.</P> <P><B>Patients and Methods</B></P> <P>A total of 1103 patients with curatively resected stage II/III rectal cancer who had available polymerase chain reaction-based MSI results were included in the final analysis.</P> <P><B>Results</B></P> <P>Twenty-four (2.2%) patients in the total cohort were found to be MSI-high (MSI-H). In univariate analysis, neither disease-free survival (DFS) nor overall survival (OS) demonstrated significant differences between patients with MSI-H tumors and those with MSI-low (MSI-L) or microsatellite stable (MSS) tumors. The 5-year DFS rate was 78.0% in MSI-H patients and 69.9% in MSI-L/MSS patients (hazard ratio [HR], 0.84; 95% confidence interval [CI], 0.35-2.02; <I>P</I> = .689). The 5-year OS rates for MSI-H and MSI-L/MSS patients were 84.0% and 83.1%, respectively (HR, 0.86; 95% CI, 0.27-2.69; <I>P</I> = .790). By multivariate analysis, the MSI status did not affect either the DFS (HR, 1.00; 95% CI, 0.40-2.47; <I>P</I> = .994) or OS (HR, 0.85; 95% CI, 0.26-2.73; <I>P</I> = .778).</P> <P><B>Conclusions</B></P> <P>MSI-H tumors are rarely observed in rectal adenocarcinoma, and the MSI status may not affect the survival outcome in patients with a resected rectal cancer.</P>

Collagenous colitis is a clinicopathological syndrome characterized by: (1) chronic watery diarrhea and crampy abdominal pain and (2) thickened subepithelial collagen band and increased intraepithelial lymphocytes on histology. The mucosa generally appears endoscopically normal, although some nonspecific abnormalities such as patchy erythema, an abnormal vascular pattern or erythema may be found in upto one third of cases. Collagenous colitis is generally regarded as a benign disease and serious complication are uncommon. The frequency of colonic perforation in collagenous coliltis is unknown, but is probably very rare. Only 16 patients, excluding our cases, have so far been reported. We report a case of a 80-year-old woman with collagenous colitis who presented with colonic perforation two days after the colonoscopy. (Intest Res 2007;5:77-80)
