임베디드 시스템은 임의의 시스템에 내장된 형태로 구성되고, 특정 하드웨어 구성요소를 제어하기 위하여 사용되며, 제한되고 전문화된 기능을 수행하는 장치이다. 임베디드 시스템에서 호스트간의 데이터 전송을 용이하게 하는 문서 정의 형식으로 향후 XML이 사용될 전망이다. 임베디드 시스템은 특정한 기능을 수행하기 위한 최소 용량이 요구되고 임베디드 시스템의 다양한 메모리 제한성에 부합할 수 있게 컴포넌트화도 요구된다. 본 논문에서는 임베디드 시스템에서 실행되는 응용을 위한 XML SAX2파서, mSAX를 소개한다.

Various time series representation methods have been proposed for efficient time series clustering and classification. Lin et al. (DMKD, 15, 107-144, 2007) proposed a symbolic aggregate approximation (SAX) method based on symbolic representations after approximating the original time series using piecewise local mean. The performance of SAX therefore depends heavily on how well the piecewise local averages approximate original time series features. SAX equally divides the entire series into an arbitrary number of segments; however, it is not sufficient to capture key features from complex, large-scale time series data. Therefore, this paper considers data-adaptive local constant approximation of the time series using the unbalanced Haar wavelet transformation. The proposed method is shown to outperforms SAX in many real-world data applications.

The effects of feed moisture content (25, 35, and 45%), screw speed (230, 250, and 270 rpm), and barrel temperature (130, 140, and $150^{\circ}C$) on the product yield and soluble arabinoxylan (SAX) content from destarched corn fiber (DCF), and its optimization were investigated. The yield and SAX content of corn fiber gum (CFG) from the extruded destarched corn fiber (EDCF) were higher than those of DCF. Statistical analyses revealed that the feed moisture content and barrel temperature had a significant effect on the CFG yield and total SAX content. The optimum extrusion pretreatment conditions were as follows: feed moisture content, 30%; screw speed, 260 rpm; barrel temperature, $133^{\circ}C$. This study showed that the response surface methodology was suitable for the optimization of the extrusion conditions used to maximize the CFG yield and total SAX content from EDCF.

The effect of feed moisture contents (30%, 40%, and 50%) and screw speed (200 rpm, 250 rpm, and 300 rpm) on the corn fiber gum (CFG) yield and soluble arabinoxylans (SAX) content of destarched corn fiber was investigated. The CFG yields and SAX contents of extruded, destarched corn fiber were higher than that of destarched corn fiber. In extruded, destarched corn fiber, increased screw speed and decreased feed moisture contents resulted in a higher SAX contents. The maximum yields of CFG obtained from extruded, destarched corn fiber were $79.1{\pm}19.0g/kg$ (30% feed moisture content) and $82.3{\pm}11.30g/kg$ (300 rpm screw speed). The highest SAX content was also observed at a screw speed of 300 rpm. The results of the present study show that water extraction and extrusion combined have the potential to increase CFG and SAX yields from corn fiber.

In this paper, we have developed an E-book reader for EBKS XML documents on the embedded Linux environment. This reader operated on a Linux target board parses the EBKS XML documents using the Qt SAX interface and displays the parsed pages through the QWS (Qt Windows System) which is a cross-platform windows toolkit. This reader can be easily and rapidly developed on Linux as well as MS windows and requires less memory than DOM interfaces because it parses with SAX interface.

Conventional medicines have usually sorted to a number of treatments such asoperation, radiotherapy, and chemotherapy. The existing anti-cancer agents, designed to eradicate cancer cells, have strong toxicities, also with leading to harmful side effects. Recently, a number of researches on natural products have been actively carried out in efforts to develop new treatments that can decrease side effects or increase anti-cancer effects. We performed this study to understand the molecular basis underlying the antitumor effects of Pharbitis nil, and Plantago asiatica, which have been used for herbal medicinal treatments against cancers in East Asia. We analyzed the effects of these medicinal herbs on proliferation and on expression of cell growth/apoptosis related molecules, with using an AGS gastric cancer cell line. The treatment of Pharbitis nil dramatically reduced cell viabilities in a dose and time-dependent manner, but Plantago asiatica didn't. FACS analysis and Annexin V staining assay also showed that Pharbitis nil induce apoptotic cell death of AGS. Expression analyses via RT-PCR and Western blots revealed that Pharbitis nil didn't increase expression of the p53 and its downstream effector p21/sup wafl/, and that the both increased expression of apoptosis related Sax and cleavage of active caspase-3 protein. We also confirmed the translocation of Sax to mitochondria. Collectively, our data demonstrate that Pharbitis nilinduce growth inhibition and apoptosis of human gastric cancer cells, and these effects are correlated with down- and up-regulation of growth-regulating apoptotic and tumor suppressor genes, respectively.

Various time series representation methods have been suggested in order to process time series data efficiently and effectively. SAX is the representative time series representation method combining segmentation and discretization techniques, which has been successfully applied to the time series classification task. But SAX requires a large number of segments in order to represent the meaningful dynamic patterns of time series accurately, since it loss the dynamic property of time series in the course of smoothing the movement of time series. Therefore, this paper suggests a new time series representation method that combines PIPs detection and Persist discretization techniques. The suggested method represents the dynamic movement of high-diemensional time series in a lower dimensional space by detecting PIPs indicating the important inflection points of time series. And it determines the optimal discretizaton ranges by applying self-transition and marginal probabilities distributions to KL divergence measure. It minimizes the information loss in process of the dimensionality reduction. The suggested method enhances the performance of time series classification task by minimizing the information loss in the course of dimensionality reduction.

Drosophila Sog and vertebrate Noggin play important roles during development. They function as antagonists against BMP4 signaling and induce neural ectoderm during embryogenesis. They are also engaged in appendage formation by inhibiting BMP4 signaling during late development. To understand further functions of Sog, Supersog, which is a more potent form of Sog, and Noggin BMP4 antagonists during development, I performed the molecular genetic analysis using Drosophila embryogenesis and wing formation as assay systems. In cellular blastoderm embryos, Sog inhibited Dpp signaling, Drosophila BMP4 signaling, whereas Supersog or Noggin did not block Dpp signaling. During wing formation, Sog inhibited Sax type I receptor of Dpp signaling whereas Noggin inhibited Tkv type I receptor of Dpp signaling. However, Supersog inhibited both Sax and Tkv type I receptors. These results suggest that functions of BMP4 antagonists are developmental stage dependent and indicate that each BMP4 antagonist inhibits BMP4 signaling by blocking different BMP4 receptors.
