A Web-based Survey for Assessment of Korean Medical Treatment Clinical Practice Patterns for Neck Pain and Cervical Intervertebral Disc Displacement※ Chang Yong Suh1,2, Yoon Jae Lee2, Me-riong Kim2, Young Hyeon Bae1, Ho Sun Kim1, No Hyeon Kim1, Kyu Jin Yang1, Gi Bum Lee1,2 and In Hyuk Ha2,* 1Department of Acupuncture and Moxibustion, Jaseng Korean Medicine Hospital 2Jaseng Spine and Joint Research Institute, Jaseng Medical Foundation Objectives : While neck pain is highly prevalent in Korea, studies examining its Korean medical treatment are currently lacking. The aim of this study was to assess current Korean medical treatment practice patterns for neck pain. Methods : A preliminary questionnaire was developed to investigate current practice patterns of neck pain and cervical intervertebral disc displacement (IDD) treatment, and underwent further revision through external review. The final questionnaire was distributed as a webbased survey to 18,289 potential respondents by email. Results : The response rate was 3.34 %. Most participants replied that they received multiple Korean medicine interventions for neck pain treatment consisting of such methods as acupuncture, wet cupping, interferential current therapy and electroacupuncture. A total of 378 respondents acknowledged that diagnostic testing was needed for neck pain treatment. The most commonly used Korean Standard Classification of Diseases (KCD) principal diagnosis code for neck pain was M542, and for cervical IDD was M501. Conclusion : This survey study helps determine current practice patterns of neck pain, and recognizes the need for use of diagnostic devices in neck pain treatment. These results are further anticipated to provide basic data for clinical practice guidelines (CPGs) and future studies using Korean National Health Insurance and Health Insurance Review & Assessment Service data.

X-밴드 선형/원형 편파 변환기의 설계 및 근거리장 해석

In this paper, we proposed the grating parallel plate waveguide structure for converting a linearly polarized wave to a circularly polarized wave. For the design of the polarizer, the moment method and Floquet's theorem are applied under two assumptions that the incident wave is a plane wave and the structure is infinitely periodic. In order for the more precise design, we performed the near-field analysis for the finite polarizer structure using MATLAB. By comparing with the measured results obtained by the near-field arrangement, we verified the correctness of our near-field analysis. By taking the ideal assumptions considered in the initial design procedure into account, newly designed modified dimensions for the polarizer was suggested which give improved performance. 본 논문에서는 수평 편파를 원형 편파로 변환시키기는 평행평판 도파관 격자 구조의 편파 변환기를 제안하였다. 편파 변환기의 설계는 입사파가 평면파이고 무한 주기 구조라는 가정하에 적분방정식을 이용한 모멘트법과 Floquet 이론을 적용하여, X-밴드에서 최적화된 평판 격자간의 간격 및 전파 진행방향으로의 길이를 결정하였다. 설계를 통해 제작된 편파 변환기를 모델로 하여 유한 주기 구조와 근거리장에 대한 해석을 MATLAB을 이용해 계산하고, 근거리장 배치 하에서 측정된 결과와 비교하여 근거리장 해석에 대한 타당성을 검증하였다. 설계에서의 가정에 대한 오차를 분석하여 개선된 특성을 갖는 편파 변환기의 수정된 설계값을 제시하였다.

Objectives : Previous studies have shown that the amount of melittin, the main active ingredient in bee venom pharmacopuncture, tends to decrease substantially with time during pharmacopuncture manufacture. This study aimed to assess whether the stability of bee venom pharmacopuncture improved with pharmacopuncture additives. Methods : Components were measured using high performance liquid chromatography. Acute toxicity and antigenicity tests by subcutaneous and venous routes were conducted at Korea Pharmaceutical Test & Research Institute and mortality, adverse reactions, and body weight changes were assessed. Results : Stability tests using additives revealed that bee venom without additives was most stable. Bee venom pharmacopuncture without additives was further tested for toxicity in subcutaneous and venous administration in mice and no changes pertaining to toxicity were found over the testing period. Conclusions : Bee venom pharmacopuncture without additives was found to be most stable, and further, it did not show toxicity or antigenicity in subcutaneous and venous administration in mice.

Objectives : This study was performed to assess the effectiveness of conservative Korean traditional medical treatment on lumbar intervertebral disc herniation in 12 adolescents. Methods : Data were collected from adolescent patients diagnosed with lumbar intervertebral herniation by MRI, hospitalized at Jaseng Korean Medicine Hospital from January 1, 2014 to December 31, 2015. A total of 12 patients were included in the study. Patients were treated by acupuncture, pharmacopuncture, electroacupuncture, herbal medicine, chuna manual therapy, physical therapy during hospitalization period. To measure treatment outcomes, a verbal numerical rating scale (VNRS), Oswestry disability index (ODI), range of motion (ROM), Straight leg raising test (SLR), and EQ-5D were used. Results : The average age of the participants was 16.05±1.62. The average of duration of symptom was 19.25±26.83 (weeks) and the average length of hospitalization was 23.8±16.4 (days). 2 patients (17 %) suffered from only lumbar pain, while 10 patients (83 %) suffered from lumbar and leg pain. No participant suffered from only leg pain. 8 patients (67 %) were diagnosed with disc herniation in one segment, and 4 patients (33 %) were diagnosed with disc herniation in multiple segments. A total of 17 disc segments (28 %) were herniated. The most herniated lumbar level was L4-5. 3 segments were diagnosed with bulging (17 %), 6 with protrusion (35 %), and 8 with extrusion (47 %). Extrusion was the most frequent herniated type. After treatment, the average VNRS of lumbar pain significantly decreased from 5.58±1.62 to 2.91±1.56 (p<0.001) and the average VNRS of leg pain significantly decreased from 5.16±2.51 to 3.08±1.8 (p<0.001). ODI significantly decreased from 48.87±18.72 to 28.57±15.05 (p<0.05), and EQ-5D significantly increased 0.58±0.31 to 0.80±0.12 (p<0.05). Range of flexion significantly improved from 61.25±32.62 to 68.33±26.22 (p<0.05). Conclusion : Conservative Korean Traditional Medical Treatment may be effective in the treatment of lumbar intervertebral disc herniation in adolescence. However, more case reports and clinical research are needed.

A Review of Research on the Effects of Acupuncture and Moxibustion Treatment to Complex Regional Pain Syndromes Ho Sun Kim1,2,*, Young Hyun Bae1, Hae Sol Kim1, Chang Yong Suh1, No Hyeon Kim1, Kyu Jin Yang1 and Gi Bum Lee1 1Department of Acupuncture and Moxibustion Medicine, Gang-Nam Jaseng Hospital 2Department of Science in Korean Medicine, Graduate School, Kyung Hee University Objectives : This study was performed to review articles concerning acupuncture or moxibustion treatment for Complex Regional Pain Syndromes. Methods : On-line databases including PubMed, Cochrane Library, Ovid-EMBASE, NDSL and OASIS were searched to find articles concerning acupuncture or moxibustion treatment for Complex Regional Pain Syndromes. Several overlapping articles and those not relevant to the topic were excluded, as well as review articles and commentaries. Results : 16 case reports were selected through the procedure, all of which presented successful treatment cases of Complex Regional Pain Syndromes with acupuncture and moxibustion. Most of them presented one single patient case and were published in Korea. However, almost half of them were printed in English, and had been continuously published since 2005. It was remarkable that pharmacopuncture was predominantly used to treat Complex Regional Pain Syndromes. Also, we noted that Chinese scalp acupuncture needs to be studied further as two successful cases were presented from the U.S army. Conclusion : The results show that several case reports have been published regarding Complex Regional Pain Syndromes treated with acupuncture and moxibustion. However, all of them were case reports which are given low status in Evidence-Based Medicine. We expect that a more diverse range of articles, including case control studies, cohort studies and randomized controlled trials will be performed in the near future, and that a unified outcome measure will be developed for Complex Regional Pain Syndromes.

Objectives : Most of pains are important symptoms caused by cancer transpered to spine. Harpagophyti Radix Pharmacopuncture is highly effective in reducing fever, pain, inflammation but was never used to reduce pain from cancer transpered to spine. So I intended to use Harpagophyti Radix Pharmacopuncture to control pain. The purpose of this study is to evaluate the clinical application of Harpagophyti Radix Pharmacopuncture for Bone Metastasis of Breast Cancer and Spinal Stenosis. Methods : We examined patient with Bone Metastasis of Breast Cancer and Spinal Stenosis who admitted Jaseng Korean Medicine Hospital. The patient was treated by Korean Medicine treatment and Harpagophyti Radix Pharmacopuncture. This case was assessed by Numerical Rating Scale(NRS), Oswestry Low Back Pain Disability Index(ODI), Short-Form 36 Health Survey(SF-36), ROM(Range of Movement) and Special Test. Results : In this study, the patient's pain was controlled and NRS, ODI were decreased. I could identify the improvement in life quality from the positive change of SF-36 and also found out that treatment was successful from the improvement of ROM, Special test. Conclusions : Harpagophyti Radix Pharmacopuncture with Korean Medicine treatment for Bone Metastasis of Breast Cancer and Spinal Stenosis was proved to be useful to the pain relief and function recovery, but further research should take place for clear understanding of the exact amount of dosage and safety. Moreover it must be accompanied by long term follow up research.

Objectives : To determine the effectiveness of Chuna manual therapy for neck pain Methods : We searched 7 electronic databases(OASIS, NDSL, Ovid-MEDLINE, Ovid-EMBASE, Cochrane library, AMED, CNKI) to find all Randomized controlled trials that used Chuna manual therapy as a treatment for neck pain. The methodological quality of each RCT was assessed by the Cochrane risk of bias tool. Results : 7 RCTs met our inclusion criteria. The meta-analysis of 7 studies showed favorable results for the use of Chuna manual therapy. High risk of bias were observed for performance bias and detection bias. Conclusions : Our systematic review found favorable results using Chuna manual therapy for neck pain. But there are several limitations in our study due to lack of well-designed RCT. To obtain stronger evidence, further clinical trials would be needed.
