Purpose: The purpose of this study was to identify the effects of Koryo Hand-Acupuncture on health status(pain, trunk flexion, IADL, depression) of patients with chronic low back pain. Method: This study used a quasi experimental pre-test and post-test design. Data were collected from December 1st, 2000 to December 20th, 2001. 63 chronic low back pain patients(35 experimental group, 28 control group) admitted to the Back-School and consented to this study. The experimental group participated in treatment: Koryo Hand-Acupuncture and AB-Bong. Two groups was homogeneity. After 4 weeks the effects of treatment on the health status was measured between experimental and control group. Data were analyzed using SPSSWIN 10.0 with crosstab, t-test, and paired t-test. Result: In the experimental group, pain(t=4.85, p=.000) and IADL difficulty(t=2.05, p=.045) was significantly lower than those in the control group. It makes no difference trunk flexion(t=-1.60, p=.114) and depression(t=1.50, p=.138) between experimental and control group. Conclusion: These findings indicate that Koryo-Hand Acupuncture is an effective method for reducing pain and IADL difficulty in patients with chronic low back pain, and is considered as a independent nursing intervention for chronic low back pain.

Background: Compared to healthy people, patients with chronic lower back pain have reduced balance abilities which may cause proprioception problems, patients with chronic lower back pain avoid physical activities due to pain, and reduced activity levels lead to muscle weakening, which can further exacerbate pain. Recently, there have been many studies on the use of sensory stimulation; and among these studies, interventions that use vibrational stimulation have shown functional improvements in the patients. Objects: This study examined the effects of a stabilization exercise with vibration stimulation on the balance ability and disability in patients with chronic back pain. Methods: The subjects of the study were 30 persons who were randomly assigned to the experimental group and the control group, with 15 subjects in each. The subjects were evaluated before and after intervention via a balance ability test, the Korean Oswestry disability index (KODI) test, a pain test, and a proprioceptive sensory test. Both groups received general physical therapy. The experimental group performed the stabilization exercise with vibration stimulation, and the control group performed a general stabilization exercise, three times a week for six weeks. Results: After the intervention, both groups showed significant improvements in the balance ability test, the KODI test, the pain test, and the proprioceptive sensory test. The experimental group showed statistically significant, higher improvements than the control group in the balance ability test, the KODI test, and the proprioceptive sensory test. Conclusions: The stabilization exercise with vibration stimulation for patients with chronic back pain has been reported to provide greater functional improvements than the conventional intervention method. Therefore, the stabilization exercise in a vibration stimulation environment could be a useful intervention for patients with chronic back pain.

This paper proposes a repeat-back jamming signal detection scheme using a correlation ratio test metric of a combined pseudo-random noise signal for global navigation satellite systems. The correlation ratio test metric allows for the monitoring of possible distortions in the signal correlation. The proposed scheme is a modified version of the correlation ratio test metric to detect a repeat-back jamming signal in a multipath environment. Through a Monte-Carlo simulation, it is confirmed that the proposed scheme detects almost the whole case, which is received a repeat-back jamming signal under the 6 dB jamming to signal power ratio.

The mold transformers have been widely used in underground substations in large building and have some advantages in comparison to oil-transformer, that is low fire risk, excellent environmental compatibility, compact size and high reliability. In addition, the application of mold transformer for outdoor is possible due to development of epoxy resin. The mold transformer generally has cooling duct between low voltage coil and high voltage coil. A mold transformer made by one body molding method has been developed for small size and low loss. In this paper, the proto type mold transformer of 50kVA class is investigated by routine, type, special test. The outdoor energized aging test is investigated by back-to-back method to verify the long time performance of pole mold transformer. The aging process of transformer is analyzed by various diagnosis method such as DC voltage-current test, $tan{\delta}$, Meggar measurement, winding temperature and etc.

PURPOSE: Postural and structural asymmetry due to muscle imbalances around the lower back and pelvis are the causes of back pain. Muscle imbalances in patients with chronic low back pain affect the pelvic tilt and movement, and it is necessary to assess the pelvic movement ability using the appropriate tools to determine the mediating effects of lower back pain. This paper reports the reliability and validity of the Sensbalance Therapy Cushion (STC) for pelvic movement and proprioception. METHODS: In this study, the Wii balance board (WBB) was used as a golden standard for pelvic movement measurements. FABQ, KODI, Myovision, and Pelvic movement were measured in 50 patients with chronic low back pain. The correlation between the lower-back muscle activity and pelvic movement was checked. The pelvic movement parameter was measured twice to determine the intra-rater reliability. RESULTS: The STC showed high test-retest reliability in the pelvic tilt measurements (ICC = .672 - .809). The test-retest reliability of proprioception measurements (ICC = .588 - .859) and reaction time measurements (ICC = .542 - .836) were also high. The relationship between the WBB and STC showed a significant positive correlation with the pelvic tilt test (p < .01). The posterior pelvic tilt and lower-back muscle activity showed a significant negative correlation (p < .01). The pelvic left tilt and lower-back muscle activity showed a significant negative correlation (p < .05). CONCLUSION: The results revealed the high reliability and validity of the STC. Therefore, the STC can be used as an objective measuring device for evaluating pelvic tilt, proprioception, and reaction time in low back pain patients.

Purpose: This study aimed to identify pain, disability, anxiety, depression and educational needs between acute and chronic low back pain groups. Methods: A total of 153 patients aged 18 to 64, recruited from S-neurosurgical clinic for low back pain in Gyeonggi-do. Out of 153 subjects, 70 were Acute Low Back Pain (ALBP) group and 83 were Chronic Low Back Pain (CLBP) group. The collected data was analyzed using the SAS System V 9.4 program by chi-square test/Fisher's exact test and t-test. Results: The pain and disability scores were higher in ALBP group while the depression score was higher in CLBP group. The educational needs score in the area for the time for lumbar operation was higher in CLBP group. In the Low Back Pain (LBP) treatment management, ALBP group visited clinic (60.0%) most frequently and CLBP group visited both clinic & traditional medicine (66.3%) regularly. Conclusion: In order to minimize the progression from acute to chronic LBP, it is necessary for patients who visited the clinic to be accompanied with an education program that reflects educational needs of patients and with proven alternative therapy.
