Background: Myofascial pain syndrome (MPS) is a regional musculoskeletal pain disorder that is caused by myofascial trigger points. The objective of this study was to determine the prevalence of MPS among chronic back pain patients, as well as to identify risk factors and the outcome of this disorder. Methods: This was a prospective observational study involving 126 patients who attended the Pain Management Unit for chronic back pain between 1st January 2009 and 31st December 2009. Data examined included demographic features of patients, duration of back pain, muscle(s) involved, primary diagnosis, treatment modality and response to treatment. Results: The prevalence of MPS among chronic back pain patients was 63.5% (n = 80). Secondary MPS was more common than primary MPS, making up 81.3% of the total MPS. There was an association between female gender and risk of developing MPS ($x^2$ = 5.38, P = 0.02, O.R. = 2.4). Occupation, body mass index and duration of back pain were not significantly associated with MPS occurrence. Repeated measures analysis showed significant changes (P < 0.001) in Visual Analogue Score (VAS) and Modified Oswestry Disability Score (MODS) with standard management during three consecutive visits at six-month intervals. Conclusions: MPS prevalence among chronic back pain patients was significantly high, with female gender being a significant risk factor. With proper diagnosis and expert management, MPS has a favourable outcome.

The shoulder is the most flexible joint in human body, so many people suffer from the shoulder pain. In order to improve medical care about shoulder muscle disease, Myofascial Pain Syndrome(M.P.S) is compared with the oriental medical theory. The findings of this study are as follows; 1. Myofascial Pain Syndrome(M.P.S) is the sensory, motor, and autonomic symptoms caused by myofascial trigger points. For the objectivity of the oriental medical theory, practical application is necessary. 2. The meridian and meridian-muscle of the shoulder is su-sam-yang(手三陽), su-sam-um(手三陰). Meridian-muscle theory is similar to anatomical muscle and myofascia. 3. There is similarity in the trigger point and Ashi(阿是)-point, taut band and palpable tender-point(硬結), referred pain and Hangki(行氣). In this study, myofacial pain syndrome is similar to the oriental medical theory. If myofacial pain syndrome is applicated in treatment, the cure of shoulder pain and objectivity of the oriental medical theory is improved.

The purpose of this study is to know the change of brain wave with stress by SUKI pressure alternative therapy. The experiment group was 12 students(male 6/female 6) with complained upper trapezius pain. Calculated the brain wave before and after stimulate the upper trapezius trigger point by SUKI and the stimulate time was 3min each persons(FP2, F3, F4, FP1, T3, T4, P3, P4). the experimet periods was 5times in a weeks with EEG(QEEG-S). The Date collecting used by Telescan(LXE5209). All the data was analyzed with SPSS 22.0 for window program. To compare the differences before and after the point pressure method, a corresponding sample of t-test was performed, and the statistical significance level was p<.05. The results was followed. The points of Fp2, F3, F4(*p<0.049, *p<0.042, *p<0.019) of EEG was showed a significant differences but Fp1, T3, T4, P3, P4 points did not showed. The SUKI alternative medicine techniques had a reduced effects for the some kind of brain stress. It is need to continuous research in the future.

Objectives : Floating acupuncture (FA) is a kind of newly developed acupuncture technique that contains its own apparatus. The technique has unique points that the body of the acupuncture needle stays intradermal space and manipulation is performed by shaking the needle horizontally; after manipulation, part of the needle remained in the intradermal space for 2~3 days. FA is not a common acupuncture methodology while various clinical study claims its efficacy on musculoskeletal disorders. In this study, the authors aimed to enhance the use of FA by comparing related theories. Methods : The authors reviewed classics, books, and articles related to FA, Meridian Muscle (MM), Myofascial Pain Syndrome (MPS), and Wrist-Ankle Acupuncture (WAA), and compared its characteristics by related theory, related symptoms, apparatus, and performing procedures. Results : FA was related and had various common parts with MM, MPS, and WAA, however, there were unique parts in the manipulation, apparatus, and stimulation location. FA is based on MM and MPS which pointing 'ashi points' or 'trigger points' as a treating target while FA does not stimulate the points directly. FA also targets subcutaneous space by inserting the needle horizontally as WAA does, while FA remains the needle handle part in the subcutaneous area for 2~3 days for more stimulation. Conclusions : FA has a unique manipulation procedure and potential benefit for musculoskeletal disorders despite the crude theological base written by Fu himself. Thus, developing a new explanation and patient-friendly methodology/apparatus is required for further down-to-earth studies.

Success of semiconductor/LCD industry depends on its yield and quality of product. For the purpose, FDC (Fault Detection and Classification) system is used to diagnose fault state in main manufacturing processes by monitoring time series data collected by equipment sensors which represent various conditions of the equipment. The data set is segmented at the start and end of each product lot processing by a trigger event module. However, in practice, segmented sensor data usually have the features of data asynchronization such as different start points, end points, and data lengths. Due to the asynchronization problem, false alarm (type I error) and missed alarm (type II error) occur frequently. In this paper, we propose a robust process fault detection system by integrating a process event detection method and a similarity measuring method based on dynamic time warping algorithm. An experiment shows that the proposed system is able to recognize abnormal condition correctly under the asynchronous data situation.

The purpose of this study was to investigate the effectiveness of the low-intensity ultrasound (noblelife) treatment on the pain points of upper trapezius muscle. The study recruited 20 patients who had trigger points in one side of the upper trapezius. The effectiveness of the low-intensity ultrasound treatment was assessed with subjective pain intensity using visual analog scale (VAS) and pressure pain threshold (PPT). The PPT was measured by pressure threshold algometer. Before and after the treatment, changes of pain were evaluated. Wilcoxon test for VAS data and paired t-test for PPT data were used for statistical significance. Compared to the pain intensity before the treatment, the pain intensity after treatment was significantly decreased (p<.05). Low-intensity ultrasound could be safely used in clinical application and at home for the treatment of patients with pain in upper trapezius muscle.

It is general knowledge that knee joint pain can be attributed to trauma and degenerative change around the knee joint. However most patients who have suffered from pain or limited range of motion of the knee joint show no definite pathology on X-ray or laboratory examination. We examined 242 patients with knee joint pain and found compression or entrapment of the articular nerve fiber by the tissue around the knee joint resulted in pain in almost all cases. Conclusion: by relieving the compression of the articular nerve fiber with just physical therapy and LASER stimulation on the identified trigger points, in conjunction with NSAIDs, muscle relaxants, were found to be very effective in the treatment of knee joint pain.

In this paper, we examine the points of similarity and difference between Korea, Japan, and the USA in terms of the spin-off effects of space technology on cultural life. In Japan and the USA, spin-off effects of space development research by government funded research centers are diffusive while in Korea they are interruptive. Spin-offs of research results impact cultural life via technology transfer and commercialization in businesses. This is because the Korean aerospace industry has progressed largely based on an overall system, but the promotion of internal parts and sub-systems, which can trigger technological development and spin-off effects in manufacturing, has been neglected. In the case of the KARI, the government funded research center, we argue that it is necessary for KARI to devote more resources to transfer (or promote spin-offs of) space technology to small and medium-sized businesses and other industries.

Authors have experienced the treatment for the uppermost frequent cases, herpes zoster, frozen shoulder and low back pain among those who visited our pain clinic. 1. Herpes zoster The Patients who received the treatment within 4 weeks of the onset of the disease, not only healed herpes without leaving post herpetic neuralgia but also crust formation was fast. 2. Frozen shoulder Over 90% of the patients who received suprascapular nerve block accompanied with trigger points electric stimulation was very efficient procedure, futhermore, authors felt keenly the necessity each patients co-operation and individual endurance for this treatment. 3. Low back pain An epidural steroid administration to the patients who did not have any organic disturbances was effective treatment. If this non-effective, search other cause of the disease or operation was advisable one.
