Low Back Pain Prescriptions of Jin, sa tak are peculiar to using Atractylodis Macrocephalae Rhizoma(AMR). All low back pain prescriptions which are enlisted in Byunjeunggimoon, Byunjeungrok and Byunjeungokham include AMR. Whereas low back pain prescriptions which is enlisted in Seoksilbirok are 7 of 10. Preexistence of low back pain prescriptions are not necessarily used AMR. But Jin, sa tak who lived at Ming and Ching era presented AMR in low back pain treatment. AMR is able to get rid of dampness between the kidney functional area and umbilicus. The results are as follows : It is made much of the malicious dampness which is in the kidney. There are not used cold but warm and eliminating dampness herbs to invigorate kidney. It shows that Jin, sa tak who was a Taoist used invigorating and warming kidney herbs. Atractylodis Macrocephalae Rhizoma is mainly used in treating low back pain from Jin, sa tak. Jin, sa tak shows concrete prognosis to treat a disease.

In this paper, the researcher investigated whether strengthening the back muscles affects the quality of chest compressions during cardiopulmonary resuscitation by university students. A total of 50 students majoring in healthcare were included from September 2018 to November. The participants performed chest compressions during cardiopulmonary resuscitation (CPR) for 2 min after back muscle strength was measured. Then, after adequate rest, the participants repeated the back muscle strength measurements and chest compressions after taping the erector spinae muscle. The paired t-test was performed to analyze changes in chest compression quality after taping. As results, taping enhanced back muscle strength and positively affected the depth of chest compressions and the compression to recoil ratio. Taping also increased confidence and lowered fatigability during chest compressions, so the participants preferred being taped while performing chest compressions. Based on these results, taping could help emergency room medical personnel specialized in CPR to enhance the quality of CPR and relieve back pain and fatigability by strengthening the back muscles.

The result of studying papers about management of lower back pain published in domestic and foreign nursing and medical magazines in these 10 years is as follows ; 1. General characteristic of lower back pain ; 1) In sex distribution, there were more men than women in 5 papers and more women than men in 4 papers among 9 papers surveryed. 2) In age distribution, thirties to forties of patients had more lower back pain as surveyed by general hospitals and fifties to sixties of patients had more lower back pain as surveyed by oriental medical hospitals. 3) In cause factor, there were 50 to 65% of sprain, 32 to 44% of herniated intervertebral disc and 13 to 29% of degenerative changes. 4) In symtom distribution, there were 26 to 57% of lower back pain, 42 to 65% of lower back pain with radiating pain and 34 to 99% of paravertevral muscle spasm. 5) In period of pain management distribution, 18 to 40% of patients experienced pain for less than 6 months and 59 to 82% of them experienced pain for more than 6 months in 3 papers among 4 papers. 6) In surveying the treatment, 66 to 88% of patients had conservative treatment and there were treatments of general hospital, oriental medicine, self remedy and traditional practice in conservative treatment. 7) In job distribution, 12 to 50% of them were housekeepers, 23 to 31% office workers, 4.6 to 36% blue color workers and 11 to 15% students. 2. As psychological character lower back pain paients had anxiety, depression, anger-hostility, phobic anxiety, neurasthenia, hypochondriasis, and interpersonal sensitivity. 3. To distinguish the cause of lower back pain, plain lumbar roentgenogram, straight leg rasing test, eletromyelogic findings, somatosensory evoked potentials CT and MRI were performed. 4. To relieve lower back pain. epidural adhesiolysis, epidulal injection of local anesthetic in mixture with steroid, lumbar spinal root block, low level laser therapy, acupuncture like transcutaneous nerve stimulation(AL TENS), topical capsaicin and lumbar orthotics were used in medical field, and relaxation technique was used in nursing field. 5. Mckenzie's extension exercise and William's flexsion exercise for lower back pain were used in medical field and Yoga exercise was applied in nursing field. 6. The more school education and self efficacy were high, the better they had active coping lower back pain positively and the less self efficacy was the more they had serious pain. As a result of studying the paper there have been very little research for lower back pain in nursing fields of Korea and foreign countries. Because 60 to 80% of population expeience lower back pain at least more than once, it is necessary to develop the study and clinical practice for management of lower back pain.

Purpose : The purpose of this study was to examine the effects of waist mobilization technique intervention for patients with chronic back pain on balance and the low back pain disability index. Methods : The subjects were 30 patients with chronic back pain. They were sampled and divided into a manual therapy group and a spinal decompression group. 15 subjects were randomly assigned to each group. Each training in this study participated for 6 weeks, 5 times a week, once a day, 15 minutes a day. Balance ability was measured with a balance analyzer, and the low back pain disability index was measured using the Oswestry Disability Index (ODI). Results : In the balance abilities, there was a significant difference in the manual therapy group compared to the spinal decompression group. In the low back pain disability index, there was a significant difference in the manual therapy group compared to the spinal decompression group. Conclusion : The analysis results of the effect of 6 weeks of waist mobilization technique intervention on the balance and low back pain disability index for patients with chronic back pain revealed that the manual therapy is more effective for static and dynamic balance ability and the low back pain disability index. In the future, we can promote independent life skills and expect a rapid recovery of patients with chronic back pain. Based on this study, further studies are needed on the effects of balance, the mechanical properties of muscle, and the low back pain disability index depending on various manual therapy techniques.

Objectives : To investigate the clinical results of patients who were diagnosed with grade II spondylolithesis treated with Korean medicine of relaxative Chuna and Gangchuk herbal medicine. Methods : We reviewed medical records of four patients diagnosed with grade II spondylolisthesis. Each patient has taken intensive Korean medical admission treatment at Mokhuri Hospital. All patients received treatments of Gangchuk herbal medicine, relaxative Chuna and acupuncture during admission period. Before treatment and every after 7-day treatment the patient's pain and walking distance without pain were assessed. The zero minimum to ten maximum pain numeric rating scale(NRS) was used to determine the degree of pain. Results : Average admission duration was 23 days. All the patients' NRS decreased from median figure of 7.5[the minimum 7 to the highest 8] to median figure of 1[the minimum 0 to the highest 2]. Walking distance without pain increased from a median of 55 m[the minimum 20 m to the highest 100 m] to median of 165 m[the minimum 100 m to the highest 250 m]. Conclusions : Intensive conservative korean medical treatment was effective in reducing pain and functional improvement for grade II lumbar spondylosisthesis patients.

Purpose: The purposes of this study were to identify degrees of low back pain, knowledge of and educational needs for low back pain of patients with chronic low back pain and to investigate their relationships. Methods: Data were collected from questionnaires distributed to 83 patients with chronic low back pain at a hospital. Results: The low back pain score was $4.70{\pm}2.22$ out of 10. The degree of low back pain was a statistically significant difference according to gender, smoking, radiating pain and frequency and duration, daily life disturbance degree, sleep disturbance and depression. The knowledge score was 8.29 out of 13. The knowledge was a statistically significant difference according to smoking and degree of sleep disturbance. The educational needs score was 39.83 out of 50. The educational needs was a statistically significant difference according to age, duration of disease, radiating pain, standing time, depression, pain treatment experience, and treatment institutions. As the low back pain increased, the educational needs increased (r=.254, p=.021). There were no correlations between low back pain and knowledge (r=-.040, p=.720) and knowledge and educational needs (r=.061, p=.581). Conclusion: It is important to focus on items with statistically significant differences in pain, knowledge, and educational needs, and to select low knowledge and high educational needs items to develop a systematic education plan.

Background: The purpose of this research was to investigate the factors affecting the low back pain of workers in hospital. 214 subjects waking at two general hospitals in Yosu city participated in this survey. Subjects consisted of doctors, nurses, medical engineers, officers and general laborers. The survey data were collected by a written questionnaire which made out by themselves for 25 days, from fourth August to 29th August, 2008. Methods: The questionnaire consisted of four categories, general, occupational, working habitual and the daily living characteristics. The collected data were analyzed by Chi-square test based on the present or absent of low back pain. Results: 1. In the general characteristics, low back pain had no significant relationship to all factors, sex, ago, body mass index, weight and height. 2. In the occupational characteristics, the phase of distribution of low back pain had statistical significant differences in the working hours a week, satisfaction of pay, satisfaction of occupation(p<0.05). However low back pain did not significantly related to the kind of occupation, period of work and degree of stress. 3. In the habitual characteristics, low back pain was significantly influenced by working posture, frequency of using lumbar and heavy material lifting, monotonous repetition of working operation and noise(p<0.05). No significant difference was shown in the factor of convenience of chair. 4. In the daily living characteristics, low back pain shown the significant differences in walking time a day, status of health and smoking pattern(p<0.05). there were, however, no significant differences in the aspect of the kind of house and bed, sleeping attitude, driving, riding time on the vehicle, exercising, frequency of cultural life and drinking alcohol. Conclusion: when I see above resultants totally, it appears a higher incidence caused by working environment rather than living habit and then consequently compared to hospital workers, they also have high incidence like others. In order to reduce incidence of low back pain and enjoy the our life we need to educate ourselves preventing program for low back pain and try to effort for preventing of low back pain on each department and individual.

Purpose: The purpose of this study was to classify patients with chronic back pain according to the degree of their back pain, and to compare the pain dysfunction index with the qualitative changes in abdominal muscles. Therefore, we aimed to provide a basis for the treatment intervention method for patients with back pain. Methods: Twenty patients with chronic back pain were purposive sample to a group of 10 patients with a back pain index of 60 % or more and a group with less than 60 % of back pain, and the subjects who voluntarily participated in the study After receiving the letter, I conducted the research the dysfunction of back pain was measured by the Korean version of the Oswestry Disability Index (KODI), and the ultrasonic wave (Ultrasound MyLabOne, ESAOTE, Italy) And the white area index, and the abdominal muscle movement was used as the exercise instrument POWER breathe K5 (Hab direct, UK), which strengthens the respiratory muscles through threshold-muscle traction. Result: In this study, patients with chronic back pain were subjected to breathing exercises, which led to the decrease in back pain dysfunction. The ultrasonographic analysis of abdominal muscles revealed that both the white area index and muscle image density in the skeletal muscle and in the outer muscle of the abdomen gradually decreased over time. Conclusion: It is thought that introducing back pain patients to abdominal muscle reinforcement training is effective in improving the functions of the patients' muscles, thus increasing their quality of life.

Back-to-back built-up cold-formed steel un-lipped channel sections are used in cold-formed steel structures; such as trusses, wall frames and portal frames. In such built-up columns, intermediate fasteners resist the buckling of individual channel-sections. No experimental tests or finite element analyses have been reported in the literature for back-to-back built-up cold-formed steel un-lipped channel sections and specially investigated the effect of screw spacing on axial strength of such columns. The issue is addressed in this paper. The results of 95 finite element analyses are presented covering stub to slender columns. The finite element model is validated against the experimental tests recently conducted by authors for back-to-back built-up cold-formed steel lipped channel sections. The verified finite element model is then used for the purposes of a parametric study to investigate the effect of screw spacing on axial strength of back-to-back built-up cold-formed steel un-lipped channel sections. Results are compared against the built-up lipped channel sections and it is shown that the axial strength of un-lipped built-up sections are 31% lesser on average than the built-up lipped channel sections. It was also found that the American Iron and Steel Institute (AISI) and the Australian and New Zealand Standards were over-conservative by around 15% for built-up columns failed through overall buckling, however AISI and AS/NZS were un-conservative by around 8% for built-up columns mainly failed by local buckling.
