This study set out to examine the knowledge about and preventive actions against musculoskeletal diseases among dental hygiene students according to the Health Belief Model, suggest a need for programs to promote health and prevent those diseases, and investigate their relations, A survey was taken among 83 sophomores and 114 juniors at the dental hygiene major of a college in Gyeonggi Province. Analyzed by using SAS 8.0 version. The findings are as follows: 1. The sophomores and juniors scored $22.50{\pm}2.37$ and $22.29{\pm}3.01$ points, respectively, on susceptibility of the Health Belief Model with significant differences between the two groups(P < 0.01). Significant differences were also found between the sophomores that scored $18.82{\pm}2.60$ points and the juniors that scored $18.64{\pm}2.77$ points on benefit(P < 0.05). 2. The juniors experienced a higher level of pain than the sophomores with statistical significance observed on the neck, shoulder, lower back, knee, foot, and ankle(P < 0.05). 3. Of the Health Belief Model, severity had significant positive correlations with 'Placing frequently used tools near the dental technician' and 'Trying to avoid repeating the same task and diversify tasks'(P < 0.01). And benefit was positively correlated with 'Trying to reduce the frequency of bending and stretching out during treatment, 'Trying not to lean much with the neck, back, arm, and wrist' and 'Trying to maintain the torso in the neutral position'(P < 0.01). The results suggest that there should be some instructions to help dental hygiene students practice the preventive actions against musculoskeletal diseases and further prevention programs against those diseases.

Modern people is generated as musculoskeletal diseases due to incorrect posture and habit. In the case of persistent abnormal posture outbreak inconvenient to musculoskeletal diseases in daily life. musculoskeletal diseases, which began as fatigue, pain, sensory paralysis, convulsions are developed symptoms of movement disorders, depression, deformities, etc. In this paper, the unrestrained abnormal posture and habit of occurring in the seat life, have implemented a system which can be determined in less unconscious way. By placing eight pressure sensors in the seat part, determines the posture over the distribution of the weight, it is possible to determine one normal posture and eight abnormal posture that occurs frequently in daily life. To evaluate the performance of the implemented system, the attitude determination experiment was performed. The results confirmed the high performance of 97%.

Objectives This study aimed to evaluate the effectiveness of postoperative Korean rehabilitation treatment for patients with musculoskeletal disorders. Methods The medical records of patients undergoing Korean medical rehabilitation after a musculoskeletal surgery, from January 1, 2016, to December 31, 2019, were analyzed retrospectively. The effect of treatment was evaluated by using a numeric rating scale (NRS) and questionnaire for each surgical site. When the same patient was re-admitted after discharge, it was treated as the same case if it was within 7 days from the discharge date; otherwise, it was treated separately. If the period of hospitalization was within 7 days or the chief complaint was not related to musculoskeletal surgeries, the case was excluded. Results In total, 480 cases were included in this study. Acupuncture (99.8%), moxibustion (95.6%), cupping (97.5%), Chuna manual therapy (81.5%), Korean medical physiotherapy (61.0%), Daoyin exercise therapy (26.3%), and herbal medicine (87.7%) were used as the Korean medical rehabilitation treatments. A significant improvement was noted when comparing the NRS and questionnaire results for each surgical site at the time of admission and discharge. Conclusions Korean medical rehabilitation can be effectively used for patients who have undergone musculoskeletal surgeries, to relieve pain and enable returning to daily activities. However, further research with a high level of evidence is necessary to support this finding.

This paper describes the current status of musculoskeletal disorders(MSDs) and its ergonomic risk factors, including the preventive intervention in terms of the working conditions and health promotion among agricultural workers. Korean agricultural workers have been exposed to the poor working condition. They have suffered from a variety of work-related injury and diseases more than the general population or the other occupational group. MSDs are one of the most prevalent problems threatening the agricultural worker's health and quality of life. Low back pain, osteoarthritis of hip and knee joint and carpal tunnel syndrome are well known MSDs that was found easily and frequently among agricultural workers. MSDs are worsened by poor ergonomic working conditions such as heavy weight lifting, repetitive movement and awkward posture which involves squatting with long sitting work on the ground, long working hours and heavy workload which are inherent in the greater part of agricultural works. Even though Korean agricultural workers are very weak population in terms of occupational safety and health, no many studies were conducted in the past and no many social and institutional supports were provided sufficiently. We need more interests and efforts in agricultural fields to improve its working condition and to promote health status of agricultural workers.

The purpose of this study was to examine about correlation among dental hygienists' work environment, recognition on preventive education of musculoskeletal disease, the work-related musculoskeletal disease, and the work characteristics. The aim is to suggest a management plan for reducing symptom of musculoskeletal disease. The self-administered questionnaire was surveyed and collected from August 1-12 of 2011 targeting 210 dental hygienists Seoul, Gyeonggi, Daegu, Pohang. Except 5 people whose responses are not clear and who suffered accident, the analysis was made on 205 people. The collected data was analyzed by using SPSS WIN 15.0 program. As a result, dental hygienists, the average was the highest with 3.07 in 'between shoulder and neck(right side).' Seeing the pain frequency by body region, the average was the highest with 1.47 in 'ankle/calf(left side).' Seeing the appearance of having trouble in work ability related to pain experience of musculoskeletal disease by body region, the average was indicated to be the highest with 1.84 in 'knee(right side).Therefore, the agencies have to pay more attentions and efforts to ensure safety of musculoskeletal disorders in dental hygienist.

This study was to determine whether iontophoresis application of centipede venom would produce analgesic effect for clinical practice. Sixty patients suffered from musculoskeletal diseases who lived in Taejon city were analyzed by double-blind central study. After pre treatment, post treatment, post 20 minutes, post 40 minutes iontophoresis using centipede venom, we assessed the response to pin-prick sensation with Endomed 582 in myalgia patients. The results were as follows, control group showed pain threshold of 1.76, 2.03, 2.01, 2.02mA after treatment, but the pain threshold of 1.76, 2.21, 3.85, 3.87mA after iontophoresis application in study group. The pain threshold of Notermans pain score after 20-minute and 40-minute centipede venom iontophoresis group using centipede venom was higher than that after non-centipede venom iontophoresis group. The results showed that by the increasing the analgesic effect in the centipede venom iontophoresis group, especially in time of post 20 minutes after iontophoresis treatment. So we considered that the iontophoresis using centipede venom could be reduced pain of myalgia in musuloskeletal disease patients.

The objective of this study is to survey the risk factors of greenhouse vegetables farmers' work-related musculoskeletal disorders(MSDs). To offer the fundamental data for agricultural improvement of greenhouse vegetable farms, the questionnaire of MSDs and heath condition were carried out. A group of 736 workers(males=492, females=244) in 6 branches constitutes the population and database for the analysis between 2004 and 2005. The sample branch was chosen based on paper are watermelon, strawberry, tomato, melon, cucumber, lettuce. The results are as follows: 1. Smoking rates in cucumber and tomato is the highest. 2. Drinking rates in strawberry, cucumber and lettuce is the highest in males, watermelon and melon are the highest in females. 3. Regular exercise rates in melon are the highest. 4. Physical and mental fatigue in females is higher than that of males in most crops except melon. That of strawberry and tomato is the highest. 5. The prevalence rates of medical diagnosed diseases are higher in order of osteoarthritis, herniated nucleus pulposus(HNP), and hypertension. That of strawberry, melon, and cucumber is high in case of osteoarthritis; Strawberry, melon, and watermelon are high in case of HNP. 6. Prevalence rates of musculoskeletal symptoms among the various pain areas are higher in order of low back, knees, and shoulders. That of tomato and watermelon is high in case of low back; strawberry and tomato are high in case of knees. These results can be used practically for agricultural improvement of greenhouse vegetables farms to prevent MSDs.

Purpose : VDT (visual display terminal syndrome) can affect individuals who monitor or who work or play using video screens, including those of smartphones. In general, headache symptoms from overuse of these screens can appear due to eye fatigue, muscle pain in the joints of wrists or fingers, and muscle pain in the neck or shoulders. Many studies in the literature have supported standards that seek to prevent these symptoms. The incidence of musculoskeletal diseases caused by the use of smartphones is expected to increase rapidly, particularly among children and young adults, and these diseases are expected to develop into a societal problem. Therefore, in this study we investigate whether tension headaches that develop from smartphone usage can affect forward neck posture, neck pain, and quality of life. Methods : A total of 93 students from University participated in this study. We divided participants into two groups, those with tension headaches (n = 25) and those without (n = 68) and took forward neck measurements. Headaches were classified according to criteria from the International Headache Society and involved bilateral headache position, quality of pressing or tightening pain, mild or moderate pain intensity, and none due to daily physical activity. We surveyed participants using the smartphone addiction diagnosis questionnaire, the Neck Disability Index (NDI), the Headache Impact Test (HIT-6), and the Quality of Life Questionnaire. Results : Although we found no significant differences in tension headaches due to smartphone addiction diagnosis (p = 0.25), SF-36 life quality assessment (p = 0.06), and cranio-vertebral angle (p = 0.07), we found significant differences from the HIT-6 and the NDI (p <.05). Conclusion : Tension headaches are not correlated with smartphone addiction, quality of life, and forward neck angle but do have a correlation with the degree of cervical dysfunction and the effects of the headaches.
