Background: Headaches arising from cervical musculoskeletal disorders are common. Conservative therapies are recommended as the choice of first treatment. Evidence to the effects of manual therapy is inconclusive and available only during the short term. There is no evidence to exercise, and no study has investigated the effect of combined therapies for cervicogenic headache. Methods: In this study, 30 participants who met the diagnostic criteria for cervicogenic headache were randomized into two groups: experimental group and control group. The experimental group was performed myofascial release (MFR), Mulligan technique and self stretching exercises. The control group was performed electrical therapy and self stretching exercises. Assessments were performed to 30 participants before and after 4 weeks therapy. The components of assessments were headache intensity(HI), headcahe duration (HD), neck pain (NP) and neck disability index (NDI). Results: After 4 weeks therapy, HI, HD, neck pain and NDI were significantly reduced in both groups (p<.01). The HI, HD, neck pain and NDI were significantly reduced in experimental group more than in the control group (p<.01). Conclusions: Manual therapy could reduce the symptoms of cervicogenic headache.

PURPOSE: The purpose of this study was to observe the effect of pain and function according to the high and low manual passive coping strategies after whiplash injury. METHODS: The study was tested with 30 patients with neck pain. Coping was measured at after 10 days using the Pain Management Inventory. Group was divided into high passive(experimental) and low passive(control) group. All patients were equally treated with the ordinary therapy. Patients attended physical therapy for 3 times a week, for 6 weeks. Visual analogue scale (VAS) for pain, Pain Disability Index (PDI), neck disability index (NDI), were recorded both before and after the intervention. RESULTS: Each coping strategy group were evaluated after 6 weeks. VAS has been significantly reduced in both groups (p <.05). PDI and NDI was significantly decreased after the experiment before. In the experimental group (p <.001), the control group showed no significant difference. In the comparison between groups VAS was significantly reduced compared with the control group (p <.05), PDI and NDI was significantly reduced compared with the control group (p <.001). CONCLUSION: Low passive coping strategy predicts neck pain and disability recovery. It may be beneficial to assess and improve coping strategy early in whiplash injury.

Nondestructive inspection (NDI) is an integral part of structural integrity analyses of dry storage casks that house spent nuclear fuel. One significant concern for the structural integrity is stress corrosion cracking in the heat-affected zone of welds in the stainless steel canister that confines the spent fuel. In situ NDI methodology for detection of stress corrosion cracking is investigated, where the inspection uses a delivery robot because of the presence of the harsh environment and geometric constrains inside the cask protecting the canister. Shear horizontal (SH) guided waves that are sensitive to cracks oriented either perpendicular or parallel to the wave vector are used to locate welds and to detect cracks. SH waves are excited and received by electromagnetic acoustic transducers (EMATs) using noncontact ultrasonic transduction and pulse-echo mode. A laboratory-scale canister mock-up is fabricated and inspected using the proposed methodology to evaluate the ability of EMATs to excite and receive SH waves and to locate welds. The EMAT's capability to detect notches from various distances is evaluated on a plate containing 25%-through-thickness surface-breaking notches. Based on the results of the distances at which notch reflections are detectable, NDI coverage for spent nuclear fuel storage canisters is determined.

The purpose of this study was to investigate the relationship between neck posture and range of motion and neck disability index(NDI) in young adults with reduced cervical lordosis. This study selected 34 young adults with cervical lordosis reduced (Cobb's angle less than 35 degrees). The assessor measured neck flexion, extension, left lateral flexion, right lateral flexion, left rotation, right rotation and forward displacements of all subjects using cervical of range motion instrument, Then, the NDI was evaluated. After all assessments, degree for cervical lordosis was divided into two groups: bottom group(severe cervical lordosis) and top group(mild cervical lordosis). The bottom group was significantly higher in Cobb's angle, extension, left lateral flexion, right lateral flexion, left rotation, right rotation and forward displacement compared to the top group (p<.05). There was no significant difference between the two groups in flexion, NDI(p >.05). In comparison of subscale of NDI, top group was significantly higher in pain, lifting, and headache than bottom group (p <.05). In correlation analysis, Cobb's angle showed significant positive correlation with flexion, extension, left lateral flexion, right lateral flexion, left rotation and right rotation(p<.05), and showed significant negative correlation with forward displacement, NDI(p<.05). Cobb's angle showed a significant negative correlation with pain, lifting, and headache of subscale of NDI(p<.05). The findings of this study potentially suggest that neck posture may affect the cervical range of motion and pain.

In order to detect the DNA heteropolymorphism of chum salmon, selected essential genes were examined in different regional chum salmons, i.e., Korean, Japanese and American by denaturing gradient gel electrophoresis (DGGE) and real time PCR methods. From the promoter regions and introns of growth hormone, mtDNA NDI region, D-loop region, IGF-I, histone H3 and MCH2 several representative primer pairs were obtained and employed for the DGGE with the PCR products from the genomic DNAs of the different regional chum salmons. mtDNA NDI, D-loop region and IGE-I genes showed marked heteropolymorphism between Korean and American chum salmons. Intron C of growth hormone also showed a heteropolymorphism between Korean and Japanese chum salmons. Whereas heteropolnnorphism of histone liH and MCH2 genes was detected among in Korean, Japanese and Asnerican chum salmons in the examined region. The real time PCR disclosed the characteristic incremental production of target DNAs dependent on the heteropolymorphic conditions of genomic DNAa of chum salmons, thus the different regional chum salmons could be grouped by the variable incremental curies. Although the DGGE and real time PCR did not produce the identical results in this study, we suggest that the DGGE and real time PCR could be used for the primary screening of the DNA heteropolymorphism of different animal genome.

Purpose : Nephrogenic diabetes insipidus (NDI) is a rare X-linked disorder associated with renal tubule resistance to arginine vasopressin (AVP). The hypothesis that the defect underlying NDI might be a dysfunctional renal AVPR2 has recently been proven by the identification of mutations in the AVPR2 gene in NDT patients. To investigate the association of mutations in th AVPR2 gene with NDI, we analyzed the AVPR2 gene located on the X chromosome. Methods : We have analyzed the AVPR2 gene in a kindred with X-linked NDI. The proband and proband's mother were analyzed by polymerase chain reaction-single strand conformational polymorphism(PCR-SSCP) and DNA sequencing of the AVPR2 gene. We also have used restriction enzyme analysis of genomic PCR product to evaluate the AVPR2 gene. Results : C to T transition at codon 202, predictive of an exchange of tryptophan 202 by cysteine(R202C) in the third extracellular domain was identified. This mutation causes a loss of Hae III site within the gene. Conclusion : We found a R202C missense mutation in the AVPR2 gene causing X-linked NDI, and now direct mutational analysis is available for carrier screening and early diagnosis.

Objectives: The purpose of this study was to investigate the efficacy of Lijin-tang-gamibang on refractory gastroesophageal reflux disease (GERD). Methods: This before-and-after study compared the first medical examination and examination at the end of medical treatment. Twelve refractory GERD patients who visited the Department of Digestive Diseases of Kyung Hee University Korean Medicine Hospital from August 14th, 2017 to October 14th, 2017, were treated with Lijin-tang-gamibang for four consecutive weeks. The clinical characteristics of refractory GERD and the efficacy of herbal medical treatment was assessed by questionnaires, the Nepean Dyspepsia Index-Korean version (NDI-K), the Korean Gastrointestinal Symptom Rating Scale (KGSRS), the Numerical Rating Scale (NRS), the Korean version of the Perceived Stress Scale (KPSS-10), the Qi Stagnation Questionnaire (QSQ), the Spleen Qi Deficiency Questionnaire (SQDQ), and the Patient Global Impression of Change (PGIC). Prolonged effects were reported upon the follow-up telephone survey two weeks after treatment. Results: After treatment with the herbal medicine Lijin-tang-gamibang, the clinical characteristics of 12 refractory GERD patients were improved, especially in terms of the most common symptoms of acid regurgitation and heartburn. Each symptom score of NDI-K, KGSRS, NRS, SQDQ, and PGIC showed significant advances. Prolonged effects were reported in NDI-K, NRS and PGIC questionnaires two weeks after treatment. Conclusions: These results suggest that Lijin-tang-gamibang is an effective treatment for refractory GERD.

Leakage magnetic flux is occurred in the cracked area of magnetized specimens, and also it changes the magnetic domain area of the magneto-optical film positioned on the specimen. It causes the change of the optical permeability of the magnetic domain on the crack area. So crack images can be obtained easily using this principle. On the other hand, utilizing a laser in this method makes possible to perform a remote sensing by detecting the light intensity contrast between cracked area and normal area. This paper shows the application of non-destructive inspection system taking advantage of magneto-optical method for micro-cracks and presents examples applied to the several types of specimens having fatigue cracks and fabricated cracks using this method. Also the authors prove the possibility of this method as a remote sensing system under the oscillation load considering application to real fields.
