Purpose: In order to keep the acceptable level of the radiation oncology linear accelerators, it is necessary to apply a reliable quality assurance (QA) program. Materials and Methods: The QA protocols, published by authoritative organizations, such as the American Association of Physicists in Medicine (AAPM), determine the quality control (QC) tests which should be performed on the medical linear accelerators and the threshold levels for each test. The purpose of this study is to increase the accuracy and precision of the selected QC tests in order to increase the quality of treatment and also increase the speed of the tests to convince the crowded centers to start a reliable QA program. A new method has been developed for two of the QC tests; optical distance indicator (ODI) QC test as a daily test and gantry angle QC test as a monthly test. This method uses an image processing approach utilizing the snapshots taken by the CCD camera to measure the source to surface distance (SSD) and gantry angle. Results: The new method of ODI QC test has an accuracy of 99.95% with a standard deviation of 0.061 cm and the new method for gantry angle QC has a precision of $0.43^{\circ}$. The automated proposed method which is used for both ODI and gantry angle QC tests, contains highly accurate and precise results which are objective and the human-caused errors have no effect on the results. Conclusion: The results show that they are in the acceptable range for both of the QC tests, according to AAPM task group 142.

Objectives : Research on the effect and satisfaction between Acupuncture Treatment, Physical Treatment and contemporary Treatments of Acupuncture and Physical of lumbago patients Methods : We separated lumbago patients into three groups. A group with only Acupuncture Treatment and a group with only Physical Treatment and a group with contemporary treatments of Acupuncture and Physical. Questionnaire survey and score of Visual Analog Scale(VAS) and Oswestry Disability Index(ODI) were examined for comparison. Results & Conclusion : 1. Of the 54 patients Acupuncture Teatment group had 17 patients with similar ratio of gender and the average age was 39.5 years old. For the Physical Treatment group the ratio of male was 75% of the 8 patients and had the youngest average age which was 29.1 years old and the group with contemporary Treatments the ratio of female was 62% of 29 patients and had the oldest average age which was 46.7 years old. 2. The Acupuncture Treatment group had the shortest treatment period because of many acute stage caused by lumber sprain and the improvement score was the best. The group of contemporary treatments had the longest history day and treatment period by serious disease like HIVD and spinal stenosis but the improvement score of VAS and ODI was good similar to the Acupuncture Treatment group. For the Physical Treatment group there was many patients with degenerative change but not severe pain. The VAS, ODI and the improvement score was the lowest before and after the treatment.

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.

Objectives : Herniation of Nucleus Pulpous (HNP) of Lumbar is one of the most common causes of low back pain. The aim of this study is to investigate the effectiveness of acupuncture, bee venom acupuncture (BVA), and bee venom Pharmacopuncture (BVP) therapy for HNP. Methods : We separated 35 patients with HNP of L-spine into three groups; Acupuncture treated group, BVA treated group, and BVP treated group, and monitored for 30 days. 4 grades of recovery degree, score of Visual Analog Scale (VAS), and Oswestry Disability Index (ODI) were examined for comparison. Results : 1. Visual Analogue Scale of low back pain and radiating pain showed significant decrease in BVA and BVP groups compared to the Acupuncture group at VAS0_2, VAS0_3 evaluations. 2. ODI of disability of daily activities showed significant decrease in BVA and BVP groups compared to the Acupuncture group at VAS0_1, VAS0_2, and VAS0_3 evaluations. 3. Compared to the Acupuncture group, BVA and BVP groups were improved in S.L.R.T and R.O.M of L-spine as confirmed by the physical examination. 4. Treatment efficacy was more apparent in acute cases as ODI was significantly lower than chronic cases. Conclusion : BVA and BVP therapies can be used in addition to the acupuncture therapy for highly effective treatment of HNP. Further clinical studies are required to verify these findings.

Objectives : The purpose of this report is to estimate Cox flexion distraction treatment by comparing the Improvement of Sciatica treated by Cox flexion distraction treatment with Common treatment. Methods : This study was carried out on 60 patients with Sciatica who were hospitalized in Dongguk University Gyeongju Oriental Hospital from February, 2008 to December, 2008. Group A of 30 patients were taken both common treatment and Cox flexion distraction treatment. And Group B of 30 patients were only taken common treatment. And at treatment conclusion day, we checked and compared VAS(Visual Analogue Scale)and ODI(Oswestry disability index) out of these two group. SPSS(Statistical Program for Social Science) for Windows was used for a statistical analysis and the independent T-test was performed to gauge the improvement of VAS(Visual Analogue Scale)and ODI(Oswestry disability index) out of these two group, in which case, value of P below 0.05 is considered as useful. Results and Conclusions : The results of the VAS(Visual Analogue Scale)and ODI(Oswestry disability index) of comparison analysis between two group at treatment conclusion day, show that the improvement of Sciatica in common treatment with Cox flexion distraction treatment Group is more effective than that in common treatment.

Purpose: To determine the therapeutic effectiveness of ultrasound-guided medial branch block (MBB) for the herniated lumbar disc patients who did not relieve their symptoms after percutaneous epidural neuroplasty (PEN). Materials and Methods: From August 2011 to February 2013, 559 patients with herniated lumbar disc have undergone PEN. Among them, ultrasound-guided MBBs were performed for the patients who had sustained low back pain and refered pain to lower extremities. Eighty eight patients were followed at 1 month and 39 patients could be followed at 6 month. All procedures have been performed by the one operator, and 23 G, 10 cm needle was placed and 0.5% lidocaine was injected under ultrasound guide. To target medial branches from L1 to L5, the groove at the root of transverse process and the base of superior articular process has been identified on transverse scan. Patients were evaluated by Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) at each follow-up. Significant pain relief was described as a 50% or more reduction in VAS and significant improvement in function was described as at least a 40% reduction in ODI. Results: VAS showed that preprocedure pain ($7.35{\pm}1.68$; $mean{\pm}SD$) significantly decreased 1 month after block ($3.36{\pm}2.98$) and 6 month ($3.05{\pm}2.27$) (p<0.05). ODI also showed that preprocedure score ($32.82{\pm}8.77$) significantly decreased at 1 month ($15.14{\pm}14.01$) and 6 month ($12.97{\pm}8.82$) (p<0.05). Significant pain relief was observed in 64.49% at 1 month and 64.10% at 6 month. Significant functional improvement in 59.81% at 1 month and 61.54% at 6 month. Conclusion: Ultrasound-guided medial branch block may sufficiently treat the facet problems secondary from disc disease.

Objectives : This research was to evaluate the MST effectiveness on iliopsoas muscle of herniated inter-vertebral disc in lumbar spine. Methods : This research was carried out with the 58 inpatients who received treatment for their HIVD in lumbar spine from January 1 to April 12, 2014 in Daejeon Jaseng hospital of oriental medicine. We randomly divided into two groups: Group A=common treatment on HIVD of L-spine without MST(acupuncture, pharmacopuncture, herb medication, chuna treating and physiotherapy) and Group B=common treatment on HIVD of L-spine with MST. To verify the MST effect, tenderness(checked by algometer pressure), NRS(numeric rating scale), and ODI(Oswestry disability index) were measured before and after treatment. The statistically significance was evaluated by SPSS 18.0 for Windows. Results : In the Group B, the tenderness was significantly decreased compared with Group A. However, on the NRS and ODI, it did not produce the meaningful results as these two values decreased in all groups. Conclusions : From this research, when patients who were diagnosed HIVD of L-spine with iliopsoas muscles tenderness receive MST additionally, the satisfaction of patients as well as physician confidence will increase.

To extract or not to extract permanent teeth for the correction of malocclusion has been a great debate in the history of orthodontics, and there is a variety of analytic methods and criteria to aid in the diagnosis. Extraction formulas that has been presented are many analytic methods that depend on arch length discrepancy, dental prominence, and skeletal pattern of the each patients. Of these analysis, the most important diagnostic factor is patient's skeletal pattern. Because the behavior of the dentition is closely dependent upon the skeletal pattern of each patient, dentition must be arranged within that person's skeletal frame. EI(Extraction Index) is composed of CF, interincisal angle, and lip position. CF is made of ODI and APDI that differentiate vertical and horizontal component of the skeletal pattern. So, EI not only represents patient's skeletal pattern, but also takes facial appearance into consideration. This study was undertaken to investigate EI and related cephalometric variables on the cephalogram of Korean adolescents which consisted of 153 persons with normal occlusion, harmonious skeleton and pleasing face. The following conclusions were obtained. 1. The mean value of the ODI is $73.5^{\circ}$, APDI $82.5^{\circ}$, CF $156.3^{\circ}$ 2. The mean value of the interincisal angle is $123.6^{\circ}$ 3. The mean distance of upper lip to E-line is 0.0mm, lower lip to E-line is 1.4mm. 4. The mean value of the EI is $153.8^{\circ}$.
