Elementary school students feel more difficult the mathematical word problems than the numberical formula. I think that this reason isn't the ability of mathematical calculation but the problems representation. It is demanded exactly understanding about the requirements of problem for improving ability of the mathematical word problem representation. It is necessary that we take multimedia data and communication for this, because web advances multimedia materialization and promotes mutual communication, then it gives us with the most environment for word problem representation learning. According to, this thesis is designed web-based system to improve ability of the mathematical word problem representation, applied the sixth grade it experimentally.

Objectives The purpose of this study was to analyze the Chuna manual therapy usage status after the application of Chuna manual therapy health insurance. Methods This study analyzed the health insurance data (2019-2021). From April 2019 to December 2021, monthly data were collected by simple Chuna, complex Chuna (own expense 50%), complex Chuna (own expense 80%), and special (dislocation) Chuna. Results The major results are as follows. First, in hospital-level medical institutions, simple Chuna and complex Chuna (own expense 50%) occupied a similar proportion. In clinic-level medical institutions, simple Chuna occupies the largest proportion. Second, the amount of use decreased in all medical institutions after September, which is thought to be the result of restrictions on Chuna manual therapy health insurance. Conclusions Therefore, it is necessary to conduct research by receiving more detailed data onr Chuna manual therapy health insurance. Through this, an improved policy of Chuna manual therapy health insurance should be discussed.

In this paper, we employ the adaptive comb filtering for effective noise reduction in mobile communication environment. Adaptive comb filtering is a well-known method for noise reduction, but requires correct pitch period and must be applied just in voiced speech frames. To satisfy these requirements we use two kinds of information extracted from speech packets, one of which is the pitch period information measured precisely by a speech coder and the other is the frame rate information related to a decision on speech or silence frame. Experiments on speech recognition system confirm the efficiency of this method. Feature parameters employing this method give superior performance in noise environment to those extracted directly from output speech.

Objectives : The purpose of this study is body parameters characteristics through posture analysis system of musculoskeletal problem patient Methods : Posture analysis system were performed for 164 patients to measure body parameters such as Q-angle, body inclination, neck inclination, PCMT(posterior cervical muscle tension), Knee flexion and posture balance. Statistical analysis using statistical analysis techniques and Pearson correlation coefficients was performed to assess the body parameters obtained by posture analysis system. Results : More than half of people out of 164 reported low back pain, 34.8% of the total was found to have neck pain. There was not a significant difference between genders from the characteristics of gender based body parameters expect for the statistical difference in Q angle, PCMT. There was a significant correlation between low back pain and multiple response status. There was a significant correlations between knee pain and Q angle. Also There was a significant correlations between pelvic pain and posture balance of ankle. Conclusions : Posture analysis system can be used to perform the analysis in place of X-ray measuring body posture and clinical parameters. The results of this study are expected to be the basis for further research on the clinical application of posture analysis system.

Historical Discourse and Intertextuality/Intra-textuality

박정식 ( Jung Sik Park ) 한국현대영미소설학회 2010 현대영미소설 Vol.17 No.1

Though intertextuality has found unique expression in postmodern fictions that are characterized as ironic, parodic, and paradoxical, this paper puts forth an alternative use of intertextuality (or intra-textual engagement), practiced at various communication levels but not duly observed, and illustrates the rich potentials and diversities of intertextual activities, which cannot be reified by any dominant language theory. With the instances of some news-reports and court transcriptions related to the Detroit Riot in 1967, as encapsulated in John Hersey`s The Algiers Motel Incident, the paper argues that the coexistence of various textual modes and epistemological frames are less the formal expression of a textual aporia than the condition of historical knowledge. The writers, whether they be historians or reporter-writers, penetrate, intersect, and saturate the historical event through various textual representations, and by so doing, they reconcile news content with narrative form, and social reality with discursive representation. Though discrete and fragmentary, these multiple textual versions of reality form a composite relationship as a story, each complementing and supporting one another, and also contradicting and floating, but, nevertheless, approximating to what Jerome Bruner calls "a properly pragmatic view of the Real."

박정식 ( Jung Sik Park ) 한국지적장애교육학회(구-한국정신지체아교육학회) 2010 지적장애연구 Vol.12 No.4

지적장애 용어의 사용이 세계적으로 점점 늘어감에 따라 미국지적발달장애(AAIDD)는 과거 10번째 편람까지 사용한 정신지체 용어를 금년 11번째 편람(2010)에서 지적장애 용어를 공식적으로 사용했다. 이러한 변화는 단순한 용어의 변화라기보다는 지적장애의 개념에 대한 철학적, 인식론적 토대에서 나타난 것이다. 이에 본 논문은 미국지적발달장애협회의 11번째 편람(AAIDD, 2010)을 포함해서 여러 단체에서 사용하는 용어가 지적장애란 용어로 이동한 주요 이유에 대해서 알아보고, AAIDD의 11번째 편람에서 지적장애의 정의 및 분류체제의 내용과 그 함의를 알아보고자 했다. In world, as use of term of intellectual disability than mental retardation is increasing, American Association on Intellectual·Developmental Disability(AAIDD) changed the term "mental retardation" that has used until 10th manual, as "intellectual disability" in 11th manual. This change has so many implications that come in philosophy and epistemology over changing term itself. The purpose of this study is to explain why term of mental retardation shift to intellectual disability that using in several associations for disabilities including AAIDD 11th Manual, and is to reveal implication of definition and classification of intellectual disability in AAIDD 11th.

Objectives Depletion of ovarian function after menopause in women induces estrogen deficiency leading to increased fat and decreased muscle mass. In this study, we examined the effect of herbal medicines by measuring hormone expression in muscle tissue of estrogen-deficient rats induced by ovariectomy. Methods Ovariectomy was performed to induce estrogen deficiency, and mice were given herbal prescription (HP) for 6 weeks. Estrogen-deficient rats were divided into two groups: one group (HPH) which were orally administered HP 200 mg/kg and the other group (HPL) administered HP 40 mg/kg. Weight changes in both groups were measured using polymerase chain reaction (PCR). After extraction of the femoral muscles in mice, the expression of the leptin, lipoprotein lipase (LPL), diacyl glycerol acyltransferase (DGAT)1, peroxisome proliferator-activated receptor-γ coactivator (PGC)-1α, NADH dehydrogenase (NDH), farnesyl diphosphate farnesyltransferase (FDFT)1, lanosterol synthase (LSS), phosphatidylethanolamine N-methyltransferase (PEMT), and peroxiredoxin (Prdx6) were measured using PCR. Results HP increased the expression of leptin, LPL, DGAT1, PGC-1α, NDH, FDFT1, LSS, PEMT, and Prdx6. HP affects body fat metabolism and is effective in improving menopausal obesity and obesity complications caused by estrogen deficiency. However, HP does not affect the expression of tumor necrosis factor-α and 3-hydroxy- 3-methylglutaryl-CoA reductase, and thus will not be effective in obesity-related metabolic diseases. Conclusions HP is thought to inhibit weight gain by regulating hormone expression related to glucose metabolism and lipid metabolism in muscle tissue of estrogen-deficient rats.

N/A Although early diagnosis of urinary tract infection is important, the radiologic evaluation is still controversial because of the low sensitivity and the lack of cost-effectiveness. This study was carried out to evaluate the clinical utility of high resolution triple head Tc-99m-DMSA SPECT imaging in urinary tract infection. We prospectively performed Tc-99m-DMSA planar and SPECT imaging, ultrasound of kidney (US), intravenous pyelography (IVP) and voiding cystourethrography (VCU) in all 60 adult patients with UTI [26 with first episode of acute pyelonephritis (APN), 22 with recurrent APN, and 12 persistent asymptomatic pyuria] and 25 normal persons. To assess reversibility of the renal cortical defect (RCD), Tc-99m-DMSA SPECT was repeated 1 to 8 months later in those patients with abnormal initial findings. Overall detection rate of Tc-99m-DMSA SPECT imaging was 83% (50/60), but planar, US, IVP and VCU showed abnormal findings in 68%, 28%, 32% and 13%, respectively. 25 out of 27 patients with nonnal or single RCD were all normal in other radioligic studies. Only two patients showed vesicoureteral reflux (VUR) on VCU (grade I) and mild hydronephrosis on IVP. But, high proportion of those with multiple RCD showed abnormal findings on US (17/33), IVP (18/33), and VCU (7/33): 67% in any of these 3 studies. Especially, 3 out 7 patients with VUR showed multiple RCD on Tc-99m- DMSA SPECT without any abnormality on IVP or US. 25 normal persons showed normal findings in all studies except one false positive finding on Tc-99m-DMSA SPECT imaging. Follow-up Tc-99m-DMSA SPECT was done in 28 patients (13 with single RCD, 15 with multiple RCD). All 13 patients with single RCD showed improvement. Those with multiple RCD presented improvement in 4, no change in 10, and aggravation in 1 on follow-up studies. With these results, we conclude: 1) Tc-99m-DMSA SPECT imaging is superior to planar imaging, US, IVP or VCU in detection of renal lesion in urinary tract infection. Tc-99m-DMSA SPECT is useful as a initial diagnostic tool in adult patients with urinary tract infection. 2) The multiple RCD on Tc-99m- DMSA SPECT represent the high probability of irreversible tissue change and need of extensive urological work-up.

Orthophotos and DEMs were generated by UAV-based aerial photogrammetry and an attempt was made to apply them to detailed investigations for the production of flood traces. The cultivated area located in Goa-eup, Gumi, where the embankment collapsed and inundated inundation occurred due to the impact of 6th Typhoon Sanba in 2012, was selected as rhe target area. To obtain optimal accuracy of UAV photogrammetry performance, the UAV images were taken under the optimal placement of 19 GCPs and then point cloud, DEM, and orthoimages were generated through image processing using Pix4Dmapper software. After applying CloudCompare's CSF Filtering to separate the point cloud into ground elements and non-ground elements, a finally corrected DEM was created using only non-ground elements in GRASS GIS software. The flood level and flood depth data extracted from the final generated DEM were compared and presented with the flood level and flood depth data from existing data as of 2012 provided through the public data portal site of the Korea Land and Geospatial Informatix Corporation(LX).
