Musculoskeletal ultrasound (MSUS) has newly evolved by the mechanical improvement of the machine over past several years, becoming a part of imaging techniques for the evaluation of variable diseases in the musculoskeletal system. MSUS has proven diagnostic superiority in pathologies including rotator cuff disease of the shoulder, lateral epicondylitis of the elbow, diseases of the peripheral nerve, detection of intra-articular loose bodies and soft tissue foreign bodies, and in evaluating small superficial soft tissue tumors such as ganglion, epidermoid cyst, and glomus tumor. Besides, MSUS is very useful for obtaining tissue or fluid via percutaneous fine needle aspiration and/or biopsy for the histopathologic diagnosis. Combining MSUS with MR would play a great role in the field of the diagnostic imaging of the musculoskeletal system. The MSUS examiner should have the knowledge of cross-sectional anatomy, and of the mechanical and physical properties of ultrasound in order to interpret the ultrasound findings accurately and properly, and to avoid diagnostic errors due to variable artifacts subsequently. The goal of this article is to introduce the capabilities of MSUS in certain kinds of clinical situation and to familiarize the reader with MSUS. For the purpose, author intends to describe this article according not to the disease-, or organ-based, but to the clinical problem-based format.

This paper proposes a method for evaluating the work of manufacturing workers using MediaPipe as a risk factor for musculoskeletal diseases. Recently, musculoskeletal disorders (MSDs) caused by repeated working attitudes in industrial sites have emerged as one of the biggest problems in the industrial health field while increasing public interest. The Korea Occupational Safety and Health Agency presents tools such as NIOSH Lifting Equations (NIOSH), OWAS (Ovako Working-posture Analysis System), Rapid Upper Limb Assessment (RULA), and Rapid Entertainment Assessment (REBA) as ways to quantitatively calculate the risk of musculoskeletal diseases that can occur due to workers' repeated working attitudes. To compensate for these shortcomings, the system proposed in this study obtains the position of the joint by estimating the posture of the worker using the posture estimation learning model of MediaPipe. The position of the joint is calculated using inverse kinetics to obtain an angle and substitute it into the REBA equation to calculate the load level of the working posture. The calculated result was compared to the expert's image-based REBA evaluation result, and if there was a result with a large error, feedback was conducted with the expert again.

The purpose of this study was to identify a tendency in patients who seek oriental medical service and factors influencing patient satisfaction. The study was conducted with 1,520 residents of a community during the period from February 5, 2005 through June 30, 2005 using a questionnaire. This study results are summarized as follows : 1. Of subjects who sought oriental medical service, 66.2% had musculoskeletal disorder and connective tissue disease, 18.9% had digestive tract disease, 16.4% had respiratory disease, 8.2% had endocrinemetabolic disease, 7.5% had circulatory disease and the remaining subjects had other diseases(p<0.001). 2. Of subjects who sought oriental medical service for the treatment of musculoskeletal disorder, 84.9% preferred acupuncture. Of those who had digestive tract diseases, 47.0% preferred packaged herbal medicine. Of those who had respiratory disease, 63.0% preferred packaged herbal medicine. 3. Acupuncture was the most often sought by subjects with musculoskeletal disorder. Packaged herbal medicine was sought by subjects with respiratory disease, digestive tract disease, endocrine-metabolic disease or circulatory disease. Tablet-type herbal medicine was sought by subjects with musculoskeletal disorder or digestive tract disease. Combined therapy was sought by subjects with musculoskeletal disorder, digestive tract disease, hematopoietic disease or immune disorder. 4. The level of satisfaction with oriental medical service was higher in subjects with circulatory disease, subjects with digestive tract disease, subjects with neurological disorder and subjects with musculoskeletal disorder in descending order. Of total subjects, 39.4% experienced side effects of oriental medical care, 38.1% experienced side effects of herbal medicine. About 51.9% considered the price of herbal medicine costly while 23.2% considered it reasonable. 5. Subjects' knowledge of herbal medicine was measured as $29.2{\pm}3.83$ out of 42 scores or 69 out of 100 points, indicating a low knowledge level. Subjects' knowledge was influenced by occupation, religion, side effects, sex, age, residence area, the type of insurance. These variables explained 15.2% of the variance. 7. Of total subjects, 56.8% were satisfied with oriental medical service. Patient satisfaction varied with occupation, religion, the type of insurance, health state and treatment outcomes. These variables explained 37.3% of the variance. Conclusion : The majority of subjects were satisfied with oriental medical service. However, oriental medical care are not widely used to treat all kinds of diseases while its use skews to a small categories of diseases. It is therefore necessary for the government and oriental medical service providers to develop new therapy approaches for the treatment of a broader range of diseases.

Objectives: This study aims to investigate the prevalence of musculoskeletal symptoms and factors related to daily activities in a representative Korean population. Methods: This study was based on the questions about musculoskeletal symptoms in the Korean General Social Survey 2010. The questionnaire about musculoskeletal symptoms was adopted from Korean Occupational Safety and Health Agency guide, and it includes general characteristics, characteristics of pain, work type, work intensity and a 12-item Short Form Health Survey (SF-12). We utilized the criteria of the National Institute for Occupational Safety and Health to define the prevalence of musculoskeletal symptoms. Demographic, behavioral and socioeconomic factors were analyzed using logistic regression. Results: The prevalence of musculoskeletal symptoms was 38.3%. The prevalence was higher in females, the elderly, those without health insurance, and those with a low income, low education, and occupations with a heavy workload. The prevalence by body part was highest in the back, shoulder, and knee, in that order. The physical component summary and mental component summary of the SF-12 decreased with increasing musculoskeletal symptoms. Conclusions: Musculoskeletal symptoms are very common in the general population, and related to various socio-demographic factors. These results suggest that active prevention and management of musculoskeletal symptoms is needed at a national level.

In the present study, the general characteristics, job stress, working conditions, and aspects of pain of some industrial workers working in Changwon-si, Gyeongsangnam-do, were surveyed. In analyzing the relationship between job stress and the existence of pain, the variables "working speed" and "opportunities to develop abilities" were shown to have statistically significant relationships with the existence of pain ($p{\leq}.05$). Regarding the relationship between working conditions and the existence of pain, the variables" amount of work per hour," "amount of work per day," "number of parts handled during work," "work production per person," and" inconvenient postures or motions during work" were shown to have statistically significant relationships with the existence of pain($p{\leq}.05$). Regarding aspects of pain", within 1~3 years" was the most common answer to time of occurrence of symptoms, with a percentage of 27.6%; "appear almost always" was the most common answer to frequency of symptoms, with a percentage of 37.1%; "slight pain" was the most common answer to degree of pain, with a percentage of 50.5%; and "moderate" was the most common answer to encumbrance caused by pain to living and work, with a percentage of 41.2%. The aim of the present study was to determine the factors that affect pain due to musculoskeletal diseases in industrial workers and to define the aspects of pain in order to provide basic data for the preparation of measures to prevent musculoskeletal diseases. To control pain due to musculoskeletal diseases, factors that affect pain, as well as the aspects of pain, should be recognized early, and efforts should be made to supplement and improve systems for preventing recurrence.
