Objective : The vertebroplasty is an excellent procedure in spine compression fracture, but there are some problems such as cement leakage and difficulties in bone biopsy. Recently, the osteoplasty system is developed to solve these problems, so we will report the usefulness of the osteoplasty system. Methods : From January 2003 to November 2003, there are 9patients with simple osteoporotic spine compression fracture, 2 compression fracture patients combined with suspicious spinal metastasis, 1patient with suspicious primary bone tumor, and 2patient with infection on spine. All patients were treated using the osteoplasty system. Results : All 11 compression fracture patients were relived the back pain after the osteoplasty and there is no complication. The bone biopsies in 3 suspicious cancer patients were also effectively performed using the osteoplasty system; negative result in 2patients and positive result in 1patient. The culture result of spontaneous discitis was no growth for 48hours. The spine tuberculosis was confirm using the osteoplasty system. Conclusion : The osteoplasty system has distinguished advantages in comparison with the vertebroplasty. That is, the risk of cement leakage is lower than vertebroplasty because of low pressure delivery system. And we can obtain the specimen effectively in bone biopsy because of large cannula. In conclusion, we emphasize that the osteoplasty system is a more useful procedure in spine compression fracture especially in the patient needed bone biopsy for diagnosis.

Objective : The purposes of this study were to evaluate the prevalence, types, and locations of Modic changes (MCs) in the thoracic spine in a large number of subjects, and to investigate the relation between the distributions of MCs and disc herniations (DHs) in the thoracic spine. Methods : Two experienced musculoskeletal radiologists assessed the presence of MCs and DHs by consensus in the thoracic MRIs of 144 patients with non-specific back pain. Patient ages ranged from 22 to 88 years (mean=$53.3{\pm}14.66$ years), and 72 were female (50%). The prevalence, distribution, relation of MCs and DHs was recorded. Results : MC was observed in 8 of the 144 patients (5.6%) and 10 of 1728 segments (0.58%). The most common MC was type II. Of the 8 patients exhibiting MC, 6 had type II (75.0%), and 2 had mixed MCs (type I/II or type II/III). MCs were distributed mainly at the mid-thoracic level (from T5/6 to T9/10). DH was detected in 18 patients (12.5%), 36 of 1728 segments (2.1%). Of the 10 segments exhibiting MC, 5 had DHs at the same level (50.0%). Accordingly, DH was strongly associated with MC (p=0.000). Conclusion : A low prevalence of MC was observed in the thoracic spine, and type II MC predominated. The low prevalence of MC in the thoracic spine suggests that it was caused by a relative lack of mobility as compared with the cervical and lumbar spines. And DHs were found to be strongly associated with MCs even in the thoracic spine.

Manual material handling(MMH)is major factor which causing physical injuries of worker at working area and frequency of low back pain(LBP) is increasing industrial accidents. Especially, working in bad circumstance such as farm, orchard, harbor loading and unloading, logging place and mining place which located in inclined slope can cause much possibility of hazard and absence of working balance can cause injuries of musculoskeletal system such as joint, bone, ligament. So, this study used EMG system to measure and evaluate muscle force information and fatigue of worker when lifting on slope. The result of measuring averaged integrated EMG(AEMG) shows multifidus muscle be used more than anything else in force. neck extensors are used at 15°, 20°frequently. generally the AEMG result shows multifidus muscle be used in force. Commonly, muscle fatigue of multifidus is higher than other muscle by analysis mean power frequency(MPF). The result of load sharing rate shows multifidus and erectorspinae which are deep spinal muscles is relatively high and neck extensor is low.

This review aimed to identify risk factors for occupational accidents and illnesses among young workers in the Nordic countries and to attain knowledge on specific vulnerable groups within the young working force that may need special attention. We conducted a systematic review from 1994 to 2014 using five online databases. Of the 12,528 retrieved articles, 54 met the review criteria and were quality assessed, in which data were extracted focusing on identifying occupational safety, health risk factors, and vulnerable groups among the young workers. The review shows that mechanical factors such as heavy lifting, psychosocial factors such as low control over work pace, and organizational factors such as safety climate are all associated with increased injury risk for young Nordic workers. Results show that exposures to chemical substances were associated with skin reactions, e.g., hand eczema. Heavy lifting and awkward postures were risk factors for low back pain, and high job demands were risk factors for mental health outcomes. The review identified young unskilled workers including school drop-out workers as particularly vulnerable groups when it comes to occupational accidents. In addition, apprentices and young skilled workers were found to be vulnerable to work-related illnesses. It is essential to avoid stereotyping young Nordic workers into one group using only age as a factor, as young workers are a heterogeneous group and their vulnerabilities to occupational safety and health risks are contextual. Politicians, researchers, and practitioners should account for this complexity in the education, training and organization of work, and workplace health and safety culture.

To investigate the period prevalence rate and therapeutic practic for low back pain (LBP) in the adult population of rural area, a personal interview was conducted for 2.024 persons or 20-59 years old in Seohu Myon, Andong County, Kyungpook Province between 1st and 20th of April, 1991. The period prevalence rate (l February 1990-31 January 1991) of LBP for 1,106 adults who were interviewed was $47.9\%$. The age adjusted period prevalence rate for males was $43.7\%$ and that for females was $52.3\%$ and the difference was statistically significant (p<0.005). Clinical course of th LBP was acute in $14.1\%$ of males and $9.0\%$ of females, recurrent in $57.0\%$ and $55.2\%$, and chronic in $28.9\%$ and $35.8\%$, respectively. Common causes of the LBP were insidious on set with aging without known cause$(48.1\%)$, heavy work $(15.1\%)$, and trauma $(11.3\%)$. Due to LBP $12.5\%$ of the patients were not able to stand or walk for more than an hour and $2.5\%$ were bed-ridden or unable to carry out daily routine. To have the LBP diagnosed $10.2\%$ of the patients utilized a oriental medical clinic or hospital, $31.3\%$ visited a clinic or hospital, and $56.6\%$ hat not utilized any medical facility. Main reason for not having the LBP diagnosed was that the LBP was tolerable. The most popular therapeutic method that the LBP patients chose at the first was drug and physical therapy. Herb medicine was most commonly used when the first therapeutic method was not effective and the acupuncture was the most popular choice of therapy when the second therapeutic method failed. Folk medicine was utilized in $15.5\%$ of the LBP patients and it included 36 regimens such as tincture of motherwort (Leonurus sibiricus), boiled chicken with liquor, etc. It was revealed by this survey that the LBP is a serious health problem in the rural area and many of the LBP patients do not utilize a clinic or hospital but take non-scientific folk remedy. To prevent the economic waste and side effects of the folk remedy, public health education is needed for tile rational therapy of LBP.

The current research examines the aching part and the muscle activity that happens during scaling practice subject to 20 dental hygienic students and therefore propose a basic data according to the working attitude of the Dental Hygienist. During the scaling we used the free EMG (BTS Inc., Milan, Italy) to measure the muscle activity, and in order to check the musculoskeletal pain area we used the Nordic-style questionnaire, and the measured research results are as following: At the moment of scaling according to posture the occurrence of the pain showed no difference among the groups elbow, back, leg, knee, ankle/foot but in the neck, shoulder, wrist/hand, waist showed a high difference in the degree of pain according to posture. Results from measuring the muscular activity according to posture, in the group that had a good posture, the trapezius and brachial muscles showed a change according to time, and in the group that had a bad posture a high muscle activity was shown in larynx, trapezius and brachial muscles. In the muscle activity, the changing aspect between the two parts, the group that fulfilled a scaling in a good posture showed a low muscle activity, but in the group that fulfilled the scaling in a bad posture the muscle activity increased excessively. Therefore we examined that when fulfilling a scaling maintaining a bad posture can help in using more effectively the activity of the muscle, in the future I think there is a need to raise the office efficiency by subjecting to dental hyginiest that are in the clinics and performing experiments.

Objectives : The purpose of this study was to propose the utilization plan of Ryodoraku in the U-health care systems. Methods : Computerized literature searches were performed for Ryodoraku related articles using the following databases: KISS, RISS, DBPIA, NDSL from 1990 to Oct 2010. Search terms were '양도락' or 'Ryodoraku' or 'U-health'. Due to Ryodoraku coming from Japan, additional literature review(articles published by 2008) on Japanese journal of Ryodoraku medicine was done for compensation. Results : 1. Introduction of U-health : As rapid progress of population aging and strong interest in health, the demand for the traditional Korean medical service is increasing. Until now healthcare service has provided post treatment by face-to-face manner. But according to related researches, proactive treatment is resulted to be more effective for preventing diseases. Particularly, the existing healthcare services have limitations in preventing and managing chronic geriatric degenrative diseases such as metabolic syndrome, CVA, coronary heart diseases, parkinson's diseases, degenerative joint disease, spondylosis, etc., because the cause of the above is complex and even related to life habit. As the advent of ubiquitous technology, patients with the chronic geriatric degenrative diseases can improve life habit such as poor eating habits and physical inactivity without the constraints of time and space through u-healthcare service. Therefor, lots of researches for u-healthcare service focus on providing the personalized healthcare service for preventing and managing that. To cope with this situations, The concept of u-healthcare service should be adopted in the traditional korean medicine and diagnostic devices suitable for it should be also devised and developed based on traditonal korean medine. 2. Review of existing Ryodoraku related articles for applying to U-health : articles investigating feasibility applying Ryodoraku to meridian diagnosis and raising problems of it, articles providing recent research trends of Ryodoraku, Ryodoraku related articles considering usefulness for U-health, and articles confirming the repeatability and reproducity of Ryodoraku were included. Based on the review of the above Ryodoraku related articles, several application of Ryodoraku in the U-health care system. Conclusions : To make preparations for the increasing need of traditional Korean medicine due to rising morbidity rate of chronic geriatric degenerative diseases, it is necessary to appropriately apply Ryodoraku to the U-health care system. The application of Ryodoraku is as follows. 1. To use Ryodoraku additionally to the established diagnostic device of metabolic syndrome, CVA, coronary heart diseases, parkinson's diseases, degenerative joint disease, spondylosis. 2. To apply Ryodoraku to the symptoms or diseases having a tendency to be diagnosed by correlation between the affected meridian and the lesion such as headache, nuchal pain, shoulder pain, low back pain, sciatica, HNP, etc. 3. To secure the repeatability and reproducity of Ryodoraku. 4. To devise and develop Ryodoraku appliance in order to overcome the known drawbacks and to improve error of measurement.

Background: This study was designed to evaluate the clinical effectiveness of traditional Korean medicine treatment for lumbar spinal stenosis as assessed by radiological criteria. Methods: This was an observational study of 122 patients who were diagnosed with lumbar spinal stenosis and admitted to Jaseng Hospital between January 2016 and June 2017. They were analyzed according to sex, age, cause of disease, disease stage, length of admission, type of stenosis, morphological grade, and dural sac cross-sectional area. All patients were treated with traditional Korean medicine. Patients were assessed with the Numeric Rating Scale (NRS), Oswestry Disability Index (ODI) and EQ-5D before and after treatment. Results: Regarding the distribution of the factors analyzed, these were of note: more females than males (1:3.52); and highest proportions were age more than 70 years (37.70%), cause of lumbar spinal stenosis unknown (67.21%), and subacute stage (42.62%). Comparing before and after treatment, the NRS score for low back and pelvic pain decreased from $6.14{\pm}1.71$ to $4.28{\pm}1.91$ (p < 0.001), and the NRS score for radiating pain and numbness decreased from $6.27{\pm}1.61$ to $2.02{\pm}1.54$ (p < 0.001). ODI decreased from $46.86{\pm}19.40$ to $33.63{\pm}18.66$ (p < 0.001), and gait-related ODI decreased from $3.34{\pm}1.23$ to $2.80{\pm}1.11$ (p < 0.001). There were no statistically significant differences in improvement of the NRS, ODI, gait-related ODI, and EQ-5D for morphological grade and dural sac cross-sectional area. Conclusion: Traditional Korean medicine is effective treatment for patients with lumbar spinal stenosis. Even in patients with severe radiological findings, it is possible to reduce pain and improve quality of life.

This study was aimed; firstly to observe various clinical symptomatology with reiation to the number of Ancylostoma duodenale larvae orally given to the human beings, secondly to evaluate the effects of some drugs like steroid hormones, antihistaminic3 and antitussives, and, thirdly to study the influences of some iron compounds in prevention and treatment of anemia of such origin. Ten healthy volunteers free from the previous history of hookworm infection were divided into 4 groups, to whom various numbers of actively moving filariform Ancylostoma duodenale larvae were orally given; 500 to 4 cases, 250 to 3 cases and 100 to 3 cases. Following were the results: 1. Clinical symptomatology 1. The most frequently encountered symptoms and signs were general malaise, cough and hoar seness. The tracheal itching and pain low back pain, arthralgia, sputum and salivation, acid belching, loss of appetite, abdominal pain and vomiting were also noted. 2. If the larger number of the larvae was given, the clinical symtomatology was more severe. 3. Prednisolone medication caused some improvement of such symptomatology, while the antihistaminics and antitussives like codeine or ephedrine were ineffective. 4. In volunteers whose nutritional conditions were rather poor appeared to show more severe symptomatology. 2. Effects of iron compounds 1. The oral administration of ferrous fumarate induced a slight increase of serum iron levels in the initial stage of the infection, then a decrease from $15{\sim}20$ days later and a recovery after 2 months. 2. The intravenous administration of saccharated ferric oxide induced a steady upkeep of the serum iron levels. 3. The hemoglobin contents also showed the upkeeps after either the oral or intravenous administration of the iron compounds. 4. The iron compounds, therefore, are considered to have the preventive as well as the therapeutic effects on hookworm anemia, which may strongly suggest that hookworm anemia is essentially the iron deficiency type. 3. Hematological changes 1. The severity of hookworm anemia generally correlated with the number of larvae given. 2. The moderate leucocytosis was observed in all cases regardless of the number of larvae given, which reached to a peak in $25{\sim}35$ days. 3. Eosinophilia was observed in all cases, but was more severe in cases given larger number of larvae, which was slightly less evident after the medication of prednisolone. 4. Red cell survival time The red cell survival time determined by $^{51}Cr$ was generally in the normal ranges except for the severe anemia patients.

This study was conducted to investigate the differences in magnetic resonance imaging (MRI) findings after lumbar epidural nerve block using the transforaminal approach and the interlaminar approach in patients with low back pain. This study was an observational analysis study of abnormal findings of MRI after epidural nerve block. This study included 78 patients who underwent MRI at approximately 24 h after lumbar epidural nerve block at a pain clinic of a university hospital between January 2007 and December 2016. Among patients who received epidural nerve block, 36 used the interlaminar approach and 42 used the transforaminal approach. The incidence of patients with abnormal changes in MRI findings was higher among patients using the interlaminar approach (53%) than those using the transforaminal approach (7%). Abnormal MRI findings included epidural air or fluid, needle tracks, and soft tissue changes, with epidural air being the most frequent abnormal finding (72%). We recommend use of the transforaminal approach to reduce the possibility of misreading or difficulty in interpretation of images of patients who underwent MRI at approximately 24 h after lumbar epidural nerve block. Practitioners should consider the possibility of abnormal findings such as epidural air on MRI in cases of epidural nerve block using the interlaminar approach.
