Objective: Herniation of Nucleus Pulpous(HNP) of L-spine is the most important reason that causes low back pain. The aim of this study is to investigate the effectiveness of Bee venom acua-acupuncture therapy for HNP. Methods: We divided HNP patient into 2 groups: Control group with acupuncture therapy only, and Experimental group with both acupuncture and bee venom acua-acupuncture therapy. To estimate the efficacy of treatment that applied for two groups, we used visual analog scale(VAS) and Oswestry disability index(ODI). We compared the VAS and ODI score of two groups statistically. Results & Conclusions: 1. In VAS, experimental group shows statitically significant improvement rate, but control group does not show statistical significance. 2. In ODI, both the experimental and control group shows statistically significant improvement. 3. By comparing the experimental and control group, there was more significant improvement in experimental group than control group of VAS and ODI. As a result, bee venom acua-acupuncture therapy can be used with acupuncture therapy for highly effective treatment for HNP.
Through-field Investigation of Stray Light for the Fore-optics of an Airborne Hyperspectral Imager

Remote-sensing optical payloads, especially hyperspectral imagers, have particular issues with stray light because they often encounter high-contrast target/background conditions, such as sun glint. While developing an optical payload, we usually apply several stray-light analysis methods, including forward and backward analyses, separately or in combination, to support lens design and optomechanical design. In addition, we often characterize the stray-light response over a full field to support calibration, or when developing an algorithm to correct stray-light errors. For this purpose, we usually use forward analysis across the entire field, but this requires a tremendous amount of computational time. In this paper, we propose a sequence of forward-backward-forward analyses to more effectively investigate the through-field response of stray light, utilizing the combined advantages of the individual methods. The application is an airborne hyperspectral imager for creating hyperspectral maps from 900 to 1700 nm in a 5-nm-continuous band. With the proposed method, we have investigated the through-field response of stray light to an effective accuracy of 0.1°, while reducing computation time to 1/17th of that for a conventional, forward-only stray-light analysis.

A decade has passed since Alvin Toffler's book "The Third Wave" described the birth of the "information society," which has brought about fundamental changes in the way we live. How much of what has been written about information technology has become reality? How much may soon come to pass. How much remain conjecture or fiction? These are all difficult questions to answer. The purpose of this paper is provided with useful information of developing systems in accounting-based expert systems, expecially taxation decision-making. which is the branch of artificial intelligence of greatest interest to us. This paper is reviewed the directions in which much of accounting-based expert systems is taking and development in the accounting field of taxation decision-making. A computer taxation department will generally contain individuals who are expert with respect to specific computer installation. The conclusion is that an accumulating knowledge-base of such expertise would be a valuable resource at least for the staff of the general taxation department who often have to consult the computer taxation department on such matters.
