Purpose : The purpose of this study was to investigate the effects of transverse abdominal muscle contraction on pulmonary function in supine position. Methods : 10 female and 10 male college students were recruited this study. Pulmonary Function test was measured with QUARK SPIRO. To check the changes in lung function with transverse abdominal muscle contraction, we tested pulmonary function in the supine, with and without transverse abdominal muscle contraction. While the transverse abdominis was activating, we investigate in the change of forced expiration. All statistical analyses were performed using SPSS Statistics VER.12.0 for window version p-values less than 0.05 were used to identify significant differences. Statistical analysis was used Paired t-test to know difference between activated and non-activated TrA of forced expiration. Results : The subject with transverse abdominal muscle contraction showed significant increments in variable of FVC, FEV1, PEF compared to the pre-intervention results (p<0.01). Conclusion : These results indicate that spontaneous contraction of the TrA helps pulmonary function. And the selective contraction of the transverse abdominis at the end of forced inspiration makes increases in the lung capacity.

Objectives: This study was performed to assess whether herbal medicine and acupuncture before in vitro fertilizationembryo transfer (IVF-ET) is effective on clinical pregnancy. Methods: From May 2010 to January 2011, a prospective analysis study was performed in 38 patients planning to undergo IVF-ET after taking herb medicine and acupuncture treatment. This study investigated the pregnancy rate and analyzed the change of dysmenorrhea by visual analog scale (VAS), body heat and condition of premenstrual syndrome (PMS), vaginal discharge and menstruation status. Results: 1. During herbal medicine and acupuncture treatment, five patients (13.16%) naturally became pregnant and six patients (15.79%) withdrew. After treatment, 15 patients (39.47%) received IVF-ET, 12 patients (31.58%) did not. 2. The biochemical pregnancy rate was 26.67%, the clinical pregnancy rate 26.67%, miscarriage rate 25% and ectopic pregnancy rate was 0%. 3. After treatment, PMS, dysmenorrhea and dysmenorrhea VAS was significantly decreased and the overall menstrual status improved. 4. After treatment, temperature difference of CV17-CV12 and CV4-CV12 increased, but it was not a statistically significant difference. 5. After treatment, decrease of hemoglobin and protein and increase of total bilirubin and creatinine were statistically significant. All the blood test results were within normal levels which proves safety of treatment. Conclusions: This study suggests that herbal medicine and acupuncture treatment before IVF-ET shows similar pregnancy rates with existing rates, but contributes to increasing the possibility of natural pregnancy.

New technologies for water purification are continuously emerging to address global water quality problems, and one such technology involves advanced hermetic water purification facilities made by concrete that utilize ozone treatment processes. Better knowledge about surface deterioration of epoxy coating exposed to ozone treatment is needed as a foundation for development of improved methods and materials in the future. This study utilized atomic force microscopy (AFM), nanoindentation methods, and existing indirect methods such as visual observation, changes in mass, surface observation and chrominance analysis, to evaluate epoxy water-resistance and anti-corrosiveness. This study considered six different epoxy formulations to assess typical degradation characteristics of epoxy surfaces with regard to water-resistance/anti-corrosiveness. AFM and nanoindentation techniques emerged as promising direct methods with potential to provide quantitative measures of surface quality that are improvements upon existing indirect methods. The experiments also confirmed that some of the epoxy-coatings were severely iMPacted by ozone exposure, and thus the results demonstrate that concern about such deterioration is justified.

Purpose: The primary aims of this retrospective study were to compare subjective bone quality and bone quality based on the Hounsfield scale in different segments of the edentulous jaw, and to establish quantitative and objective assessment of the bone quality. Materials and Methods: Twenty eight randomly selected cone-beam computed tomographic (CBCT) scans were analyzed. For evaluation one hundred and twelve edentulous areas were selected. Implant recipient sites were evaluated visually for Lekholm and Zarb classification. The same sites were subsequently evaluated digitally using the Hounsfield scale with Vimplant$2.0^{TM}$, and the results were correlated with visual classification. Data was subject for statistical analysis in order to determine correlation between recorded HU and the regions of the mouth with the Kruskal-Wallis test. Results: The highest unit/mean density value (311 HU) was found in the anterior mandible, followed by 259 HU for the posterior mandible, 216 HU for the anterior maxilla, and 127 HU for the posterior maxilla. These results demonstrate a strong correlation for HU depending on the region of the mouth (p<0.001). The relationship between HU and type 4 bone was found to be significant (r=0.74). Conclusion: Knowledge of the Hounsfield value as a quantitative measurement of bone density can be helpful as a diagnostic tool by using $CBMercuRa6^{TM}$ with $Vimplant^{TM}$ software.

A new method for early caries diagnosis was proposed and tested through a home-made optical examination system that used quantitative light fluorescence (QLF) and digital imaging fiber optic transillumination (FOTI) (DIFOTI), with light sources across a wide spectral range, from 350 nm to 1,000 nm. The front-illuminated infrared light scattering image (FIR) showed similar diagnostic abilities to that of DIFOTI. The FIR method was invented based on the observation that caries lesions lose the high transmittance and low scattering properties of benign enamel tissue. There are various methods for the early diagnosis of caries, such as visual examination, exploration, X-ray radiography, QLF, FOTI, and infrared fluorescence (diagnodent). Among them, methods based on optical properties are regarded as having the most potential. A comparative study was performed between the FOTI, QLF, diagnodent, optical coherence tomography, and FIR scattering image methods, using 20 extracted teeth samples with early caries. A scale of lesion measurement based on optical image contrast was proposed. The statistical analysis showed a significant correlation between the DIFOTI and FIR methods (r = 0.35, p < 0.05). However, the QLF and diagnodent methods showed little association with FIR images, as they have different detection principles as compared with FIR. Tomographic images obtained by OCT, using 1,330 nm super luminescent LED as a gold standard of tooth structure, verified that the FOTI and FIR results correctly represented the lack of homogeneity in dental tissue. The newly proposed FIR method attained similar diagnostic results to those of FOTI, but with an easier approach.

Due to global warming, various natural disasters such as floods and localized heavy rains are increasing. If a natural disaster can be detected and analyzed in advance and effectively, it can prevent enormous damage due to natural disasters. Recent development in visual sensor technologies has encouraged various studies on monitoring environments including rivers. In this paper, we propose a method to detect river regions from river images which can be exploited for river surveillance systems using video sensor networks. In the proposed method, we first analyze the color properties of the river region and the background region of a image and then propose a way to select the proper color channel and binarize the image to detect the river region. It is shown by experimental results that the proposed method is simple but detects river regions accurately.

The self-report measure is a useful tool for evaluating self-recognized disability and difficulty in daily living activities. Although many studies and clinics used the Neck Pain and Disability Scale (NPDS) for measuring neck pain and functional impairment, there has not been much adaptation of this for use with Korean patients. The purpose of this study was to establish the reliability and validity of NPDS among Korean neck pain patients. Fifty-five subjects (32 males, 23 females) with neck pain enrolled in this study. They completed standardized self-administered questionnaires. The NPDS measures pain intensity; its interference with vocational, emotional, recreational, social, and functional aspects of living; and the presence and extent of associated factors. Reliability was determined by the intraclass correlation coefficient (ICC) and Cronbach's alpha for internal consistency. Validity was examined by correlating the NPDS scores to the Visual Analog Scale (VAS) score. The test-retest reliability of the translated versions of the NPDS was good ICC (2,1)=.86 (95%CI .76~.92). Cronbach's alpha value for NPDS was found to be .93, and this was statistically significant (p<.05). The criterion-related validity coefficient was .79 (p<.Oll. We conclude that the Korean version of NPDS has been shown to be a reliable and valid instrument for the assessment of neck pain. Successful linguistic and cultural translation will admit appropriate cross-cultural comparison for clinical analysis. Therefore, this study can be expected to be used as an adequate evaluation scale for neck pain related studies and treatments.

Image fusion techniques are widely used to integrate a lower spatial resolution multispectral image with a higher spatial resolution panchromatic image. However, the existing techniques either cannot avoid distorting the image spectral properties or involve complicated and time-consuming decomposition and reconstruction processing in the case of wavelet transform-based fusion. In this study a simple spectral preserve fusion technique: the Smoothing Filter-based Replacement(SFR) is proposed based on a simplified solar radiation and land surface reflection model. By using a ratio between a higher resolution image and its low pass filtered (with a smoothing filter) image, spatial details can be injected to a co-registered lower resolution multispectral image minimizing its spectral properties and contrast. The technique can be applied to improve spatial resolution for either colour composites or individual bands. The fidelity to spectral property and the spatial quality of SFM are convincingly demonstrated by an image fusion experiment using IKONOS panchromatic and multispectral images. The visual evaluation and statistical analysis compared with other image fusion techniques confirmed that SFR is a better fusion technique for preserving spectral information.
