Purpose: The purpose of this study was to identify the relationships between health status including objective health status and subjective health perception and Health-Promoting Lifestyle Profile II in North Korean immigrants. Methods: During August 2011 to November 2011, a convenience sample of 96 subjects aged 19 to 65 years were recruited from two centers and one public health center in Gyeongnam. The subjects were interviewed face to face by trained people with a survey questionnaire. Results: Approximately 40% of North Korean immigrants rated their health status as 'poor', and the prevalence of health problems in them was 81.3%. The average level of health-promoting lifestyle profile II was $1.78{\pm}0.35$. Females with normal weight or overweight, and have stayed for over 1 year in South Korea were related to the lower score of health-promoting lifestyle profile II. Conclusion: Considering North Korean immigrants' health background and health behaviors, customized health care program focusing on musculoskeletal disorder and psychological problems are required, and at the same time health behavior change program to achieve lifetime wellness should be developed.

Purpose：The purpose of this study was to investigate of the change of the forward head posture(FHP) according to computer using time. Methods：Subjects were 30 male and 30 female. The factors of FHP were measured cranial vertical angle, cranial rotation angle, and head, upper back, neck flexion/extension angle according to computer using time. Change of FHP used to Digital Inclinometry(JTech, Dualer IQTM Dual Inclinometer). The data were collected by data logger(Logger Teknologi HB, Akarp, Sweden). Results：Cranial vertical angle, cranial rotation angle, and head, upper back, neck flexion/extension were increased according to computer using time(p<.05). But cranial vertical angle and cranial rotation angle, and head, upper back, neck flexion/extension were not significant differences between male and female group(p>.05). Conclusion：The effects of cranial vertical angle, cranial rotation angl and head, neck and upper back angle depend on the computer task time. Increased of FHP may result increased tension in posture muscles of cervical spine, resulting in a risk of musculoskeletal disorders.

Ochronosis is a musculoskeletal manifestation of alkaptonuria, a rare hereditary metabolic disorder occurs due to the absence of homogentisic acid oxidase and leading to various systemic abnormalities related to deposition of homogentisic acid pigmentation (ochronotic pigmentation). The present case reports the clinical features, radiographic findings, treatments and results of a cervical spondylotic myelopathy woman patient due to the ochronotic arthropathy of the cervical spine. The patient aged 62 years was presented with gait disturbance and hand clumsiness. Physical examination, X-rays, computed tomography and lab results of the urine sample confirmed the presence of ochronosis with the involvement of the cervical spine. The patient underwent a modified cervical laminoplasty due to multi-segment spinal cord compression. The postoperative follow-up showed a good functional outcome with patient satisfaction. The present study concludes the conditions and important diagnostic and surgical aspects of a patient. It is necessary to identify the condition clinically and if cord compression is observed, appropriate surgical interventions needs to be instituted.

Objectives: Few studies have reported on the flexibility of the hamstrings resulting from variable stretching method, and little studies of length adaptation at 1 day after intervention. Methods: Fifty-four healthy a woman in her twenties with no history of musculoskeletal or neurogenic disorder volunteered for this study. Subjects were randomly assigned to either a contract-relax group or a passive stretching group. Methods: Hamstring flexibility was measured with a sit and reach test(SRT) (RF-D18; SPC) before, immediatly after interventions, and 1 day after interventions. Results: Flexibility scores for participants in each of the groups significantly increased from pre-interventions to immediate and 1 day after interventions. However, the length of 1 day after interventions was shorter than immediate length after interventions. Difference in length between immediate and 1 day after interventions was some shorter in the contract-relax group versus the static group but, not significantly. Conclusions: The results of this study suggest that a contract-relax is an effective length adaptation of hamstring muscles by 1 day after intervention.

Occupational risks are often underestimated in midwifery. It is not commonly known that occupational risks were originally described by the Italian physician Bernardino Ramazzini (1633-1714) at the beginning of the 18th century. Our aim was to describe occupational risks in midwifery from Ramazzini to modern times. The original text by Bernardino Ramazzini was analyzed. A review of modern scientific articles on occupational risks in midwifery was conducted. Ramazzini identified two major occupational risks in midwifery: infections and awkward postures. Modern literature seems to agree with his considerations, focusing on infection, use of universal protection and personal protective equipment, and musculoskeletal problems. Modern studies also evidenced posttraumatic stress disorder that was probably postulated by Ramazzini himself. The poor number of articles in literature on midwives' occupational risks shows a lack of interest toward this issue. Prevention should therefore be emphasized in this field, so high-quality studies on occupational risks in midwifery are needed.

The medical fitness of pilots is part of the civil aviation safety scenery. This study aimed to analyze the health problems occurring among Korean commercial pilots. Three data sources were used to identify the health problems: 7,574 aviation medical examination data, 5,400 sick leaves and 39 cases of a decrease in medical fitness during flight duty period and layover of Korean commercial pilots who have been working for K airline from Jan. 1, 2016 to Dec. 31, 2018. This study was retrospectively analyzed using SPSS 22 statistical program. Waiver of medical certificates was an average 11.9% of total issuance for 3 years, with a denial of 0.1%. The leading cause of denial of medical certificates was predominantly of cardiovascular cause (55.6%). Mild respiratory and digestive disease accounted for 82% of total sick prevalence and 68% of total sick days. The psychiatric and cardiovascular disease were ranked high according to the number of days lost per case. The most common cause of decrease in medical fitness during flight duty period was acute abdominal pain (36.4%) and musculoskeletal disorder (40%) when staying abroad. Aeromedical emphasis on minimizing cardiovascular risk remains appropriate. Major pilot health problems identified in this study should be considered in establishing pilot health promotion programs for aviation safety.

Myofascial pain syndrome (MPS) is a common musculoskeletal disorder characterized by muscle pain, tenderness, and trigger points. Ultrasonography has emerged as a key tool for diagnosing and treating MPS owing to its ability to provide precise, minimally invasive guidance. This review discusses the use of ultrasonography in various approaches to evaluate and manage MPS. Studies have shown that shear-wave sonoelastography can effectively assess muscle elasticity and offer insights into trapezius stiffness in patients with MPS. Ultrasound-guided interfascial hydrodissection, especially with visual feedback, has demonstrated effectiveness in treating trapezius MPS. Similarly, ultrasound-guided rhomboid interfascial plane blocks and perimysium dissection for posterior shoulder MPS have significantly reduced pain and improved quality of life. The combination of extracorporeal shockwave therapy with ultrasound-guided lidocaine injections has been particularly successful in reducing pain and stiffness in trapezius MPS. Research regarding various guided injections, including dry needling, interfascial plane blocks, and fascial hydrodissection, emphasizes the importance of ultrasonography for accuracy and safety. Additionally, ultrasound-guided delivery of local anesthetics and steroids to the quadratus lumborum muscle has shown lasting pain relief over a 6-month period. Overall, these findings highlight the pivotal role of ultrasonography in the assessment and treatment of MPS.

In order to study the occurrence of symptoms of musculoskeletal disorders of radio-technologists employed at metropolitan general hospitals and the factors that influence such occurrence, standardized questionnaire by NIOSH that was modified and supplemented to be suitable for conditions in Korea was used. Answers collected from 143 radio-technologists in two weeks from June 13, 2007 were analyzed and the results are as follows. Factor that influence symptoms of musculoskeletal disorders by area were analyzed through multiple logistic regression analysis and the results found that in the neck area, risk increased as the burdening work category 2(Korea ministry of labor)(OR=3.94) and burdening work category 9(Korea ministry of labor)(OR=4.72) increased. In the shoulder region, risk increased as burdening work category 2(Korea ministry of labor)(OR=5.36), burdening work category 7(Korea ministry of labor)(OR=3.90), and burdening work category 9 (Korea ministry of labor)(OR=5.76) increased. In the arm/hand/wrist regions, risk increased as burdening work category 2 (Korea ministry of labor) (OR=6.91), and burdening work category 9 (Korea ministry of labor)(OR=3.76) increased. In the lower back region, risk increased as burdening work category 2 (Korea ministry of labor) (OR=3.06), and burdening work category 8 (Korea ministry of labor)(OR=8.14) increased. In the leg/knees/foot regions, risk increased as burdening work category 2 (Korea ministry of labor) (OR=3.63), and burdening work category 9 (Korea ministry of labor)(OR=2.96) increased. Conclusively, in factors that influence musculoskeletal disorder symptoms in radio-technologists, influence of subjective health conditions, total work experience, experience in current division, and burdening work category 2, 7, 8, and 9 (Korea ministry of labor) were most significant. Therefore, for preventive management, in addition to ergonomic and educational intervention for correcting improper posture during work, efforts for break time adjustment and stress reduction is needed, and encouragement and support for regular exercise is needed.

The purpose of this study is to establish the basic data for the management of the elderly patients aged more than 60 suffering from musculoskeletal disorders in geriatric hospitals. From January, 1 2012 to December 31, 2012, 2,500 patients who were taken the x-ray inspection and were analyzed x-ray order 5,042 cases above spines, upper lower extremities and joints. The elderly age was divided into 3 groups according to Brody elderly statistics. The majority of elderly patients who visited the hospital are exposed to spinal disorders and joint diseases. Shoulder, knee, L-spine examination cases had accounted for more than half the number of total. By age group, the number of the first quarter was most dominant commonly. Second and third quarter was maintaining slightly decrease. The fourth quarter had reduced compared to the first quarter. If the visiting purposes and the disease causes analysis and preventive measures are taken in a study, it is expected to utilize as basic data to make a plan of the education for preventing diseases and elderly behavior planning for geriatric hospitals and to redistribute health care resources of the rural areas efficiently.
