Objectives : Lumbar radiculopathy is a common disease in oriental rehabilitation medicine. It can be diagnosed by physical examination, plain X-ray, Myelography, CT, MRI, EMG etc. But those methods are not useful in observing the clinical procedure. Objectvie evaluating the clinical procedure is very important in treatment of lumbar radiculopathy. Mehthods : We studied the clinical efficacy of thermography in lumbar radiculopathy during conservative managements. We studied 36 patients with lumbar radiculopathy convinced by MRI. The had low back pain and radiating pain on one side. Thermography had taken before an after 4 weeks treatments, and compared with clinical procedure Results and conclusions : Thermography is not pertinent as a primary diagnostic method in lumbar radiculopathy, but useful in observing the clinical procedure. And it can be recommended as a objective evaluation for lumbar radiculopathy.

The digital treatment technology industry is one of the core fostering industries of the Moon Jae-in government along with the global trend. The purpose of this study is to compare and analyze the investment and economic ripple effect on the related industries. To this end, we used the industry-related table, which is the actual measurement data for 2015 that the Bank of Korea actually measured and released every 5 years in 2019. The digital treatment technology industry was not clearly classified within Korea’s industrial classification system, so the contents of the industry-related survey were analyzed, and the digital treatment technology industry was reclassified and then analyzed. As a result of the analysis, it was analyzed that the production induction effect of the digital treatment technology-related industry in 2015 was 1.770, the value-added induction effect was 0.875, and the employment induction effect was 19.128, which was higher than that of other industries in Korea. As a result of the analysis of the economic ripple effect (scenario 1), the production inducing effect was about 370 billion won, the added value inducing effect was about 185 billion won, and the employment inducing effect was 4,044 people. The results of this study are expected to play a large role in economic revitalization as the effect of inducing production, increasing employment, and creating added value through fostering the digital treatment technology industry is expected to play a large role in activating the economy. It is expected to play a large role in providing central medical services. Therefore, it is expected that policy support for revitalizing the digital treatment technology industry through active investment support and tax benefits from the government to foster the digital treatment technology industry is necessary.

<B>Graphic Abstract</B> <P>The cover shows a schematic illustration of patterned colloidal photonic crystals with different bandgap positions. When an unknown light source impinges on the patterned photonic crystals, the light information can be identified from the reflection intensity profile of the constituent photonic crystals. The two optical microscopy images and background image display integrated photonic crystals with 20 different bandgaps spanning the entire visible range, and the SEM image shows the cross-section of the photonic crystal stripes, as reported by Shin-Hyun Kim, Seung-Man Yang, and co-workers on p. 946. <img src='wiley_img_2010/09359648-2010-22-9-ADMA201090022-content.gif' alt='wiley_img_2010/09359648-2010-22-9-ADMA201090022-content'> </P>

This study was conducted to develop a simple selection method for herbicide-resistance weeds. Two methods, designated "seedling method" and "stem node method" were employed for screening of barnyardgrass against propanil and butachlor. In the seedling method, shoot and root growth of barnyardgrass were significantly inhibited at quarter of the recommended herbicide rate, while in the stem node method, the similar inhibition was obtained at half of the recommended rate. Thus, it was concluded that the seedling method is more simple and quick method to evaluate response of barnyardgrass to propanil and butachlor compared to stem node method.

The purposes of this study were to compare the bleaching efficacy of sodium perborate when mixed either with Superoxol or distilled water and to evaluate the efficacy of different location of intracoronal base on the presence of apical leakage of tested bleaching agents. Forty eight extracted human permanent incisors were stained via whole blood and canal fillings with conventional gutta percha were performed after routine biomechanical preparations. The experimental intracoronal base was placed either at the cementoenamel junction(group 3, 4) or 2㎜ below cementoenamel junction(group 1, 2). Walking bleaching was performed by two different combinations of bleaching agents ; sodium perborate with distilled water in group 1, 3 and sodium perbrate with Superoxol in group 2, 4. The roots of the teeth were evaluated for the presence of color change to assess the leakage of bleaching agents and the cervical one-thirds of the crowns were evaluated for bleaching effect from the Whiteness Index calculated by spectrophotometer. The results were as follows 1. At the end of 12 days, all the sample teeth demonstrated the increase of Whiteness Index at cervical 1/3 of crown although there were some minor differences among groups. 2. Regardless of location of the base, sodium perborate with superoxol(group 2, 4) showed better results in bleaching than the sodium perborate with distilled water(group 1, 3). 3. Bleaching agent leaked into the root area when the base was placed 2㎜ below cementoenamel junction but no leakage was found when the base was placed at the cementoenamel junction.

Colors reprodued by color image processing system are affected by various physical factors and environmental conditions. Therefore it is difficult to reproduce the original object color accurately. Thus color calibrations of the input and output data of color image processing system based on spectral distributions are required. We propose a color calibration algorithm by considering spectral characteristic of the chosen color reproduction system which can be applied to device independent color reproduction using characteristic vectors of surface reflectance. The method comprised of two steps. The first step is color analysis step which reproduces the original object color from the camera output using color characteristic vectors. The second step is color synthesis step which displays the original color accurately on the monitor by considering the monitor's phosphor spectra. The spectral responsivities of camera sensors and phosphor spectral characteristics of a given monitor are evaluated. Also, to evaluate color reproducing characteristic we applied the proposed color calibration algorithm by choosing Macbeth ColorChecker's twenty four color spectra as a test color set. As a result, we reconstruct the actual color very closely on monitor using the proposed color calibration algorithm.

Objective: To determine the effect of intradiscal therapy with discography in patients with back pain of no effect using epidural steroid. Subject and methods: Thirty patients with herniated nucleus pulposus (HNP) who had not have any improvement using repeated epidural steroid were studied. Degree of disc degeneration, provocation pain and intradiscal pressure were evaluated in 41 discs. Intradiscal triamcinolone was injected to degenerated discs and intradiscal electrothermal therapy (IDET) was performed to the patients who had no improvement using intradiscal steroid. Patients were asked to report pain according to a visual analogue scale (VAS). Results: Thirty of 41 discs showed significant degeneration. In 19 of 30 (63.3%) patients, VAS was reduced over 50% after intradiscal steroids. Low intradiscal pressure without provocation pain and ruptured discs were significantly higher in these patients (p<0.05). After IDET, 8 of 9 patients noted over 50% reduction of VAS. Conclusions: In patients with discogenic back pain combined with radicular pain, intradiscal therapy according to discography may be helpful in patients with no improvement using epidural steroid.
