Easy Detection of Amyloid b-Protein Using Photo-Sensitive Field Effect
( Kwan Soo Kim ),( Jong Il Ju ),( Ki Bong Song ) 한국센서학회 2012 센서학회지 Vol.21 No.5
This article describes a novel method for the detection of amyloid- (A) peptide that utilizes a photo-sensitive field-effect transistor (p-FET). According to a recent study, A protein has been known to play a central role in the pathogenesis of Alzheimer`s disease (AD). Accordingly, we investigated the variation of photo current generated from p-FET with and without intracellular magnetic beads conjugated with A peptides, which are placed on the p-FET sensing areas. The decrease of photo current was observed due to the presence of the magnetic beads on the channel region. Moreover, a similar characteristic was shown when the Raw 264 cells take in magnetic beads treated with A peptide. This means that it is possible to simply detect a certain protein using magnetic beads and a p-FET device. Therefore, in this paper, we suggest that our method could detect tiny amounts of A for early diagnosis of AD using the p-FET devices.

Constraints on the structure and composition of the active layer are important for understanding permafrost evolution. Soil convection owing to repeated moisture-induced freeze-thaw cycles within the active layer promotes the formation of self-organized patterned ground. Here we present the results of ground penetrating radar (GPR) surveys across a selected sorted circle near King Sejong Station, Antarctica, to better delineate the active layer and its relation to the observed patterned ground structure. We acquire GPR data in both bistatic mode (common mid-points) for precise velocity constraints and monostatic mode (common-offset) for subsurface imaging. Reflections are derived from the active layer-permafrost boundary, organic layer-weathered soil boundary within the active layer, and frozen rock-fracture-filled ice boundary within the permafrost. The base of the imaged sorted circle possesses a convex-down shape in the central silty zone, which is typical for the pattern associated with convection-like soil motion within the active layer. The boundary between the central fine-silty domain and coarse-grained stone border is effectively identified in a radar amplitude contour at the assumed active layer depth, and is further examined in the frequency spectra of the near- and far-offset traces. The far-offset traces and the traces from the lower frequency components dominant on the far-offset traces would be associated with rapid absorption of higher frequency radiowave due to the voids in gravel-rich zone. The presented correlation strategies for analyzing very shallow, thin-layered GPR reflection data can potentially be applied to the various types of patterned ground, particularly for acquiring time-lapse imaging, when electric resistivity tomography is incorporated into the analysis.

This paper tests whether exogenous shocks including agricultural policies, trade liberalization and financial crisis have impacts on the structural changes in the farm or farm household income. Unlike previous studies that specify break points prior to the estimation of regression, this paper estimates break points by fitting time series models. Tests for the structural breaks show that there is no structural break in the real farm household income whereas real farm income has five break points. Especially the break at 1997 can be interpreted as the impacts of financial crisis. The break points of 1983, 1987 and 1992 approximately match with the timings of agricultural policies that aimed better structure of agriculture and rural area were implemented. The assessed impacts of exogenous shocks at 1970, 1983, 1987 and 1992 are all positive. However, the assessed impacted of the shock at 1997 is negative. The impacts of the shock at 1997 are assessed within the range between -1,141,432 won and -3,167,804 won.

Low temperature sintering behavior and microwave dielectric properties of the BiNbO4- and the ZnNb2O6-zinc borosilicate glass (ZBS) systems were investigated with a view to applying the composition to LTCC technology. The addition of 10~30 wt% ZBS in both systems ensured successful sintering below 900 ℃. For the BiNbO4-ZBS system, the sintering was completed when 15 wt% ZBS was added whereas 25 wt% ZBS was necessary for the ZnNb2O6-ZBS system. Secondary phase was not observed in the BiNbO4-ZBS system but a small amount of Zn2SiO4 with the willemite structure as the secondary phase was observed in the ZnNb2O6-ZBS system. In terms of dielectric properties, the application of the BiNbO4- and the ZnNb2O6-ZBS systems sintered at 900 ℃ to LTCC were shown to be appropriate; BiNbO4-15 wt% ZBS (εr = 25, Q×f value = 3,700 GHz, τf = -32 ppm/℃) and ZnNb2O6-25 wt% ZBS (εr = 15.8, Q×f value = 5,400 GHz, τf = -98 ppm/℃).
