We present the concept of a Medical Digital Twin (MDT) that can predict and analyze medical diseases using computer simulations and introduce a dynamic virtual body capture system to create it. The MDT is a technology that creates a 3D digital virtual human body by reflecting individual medical and biometric information. The virtual human body is composed of a static virtual human body that reflects an individual's internal and external information and a dynamic virtual human body that reflects his motion. Especially we describe an early version of the dynamic virtual body capture system that enables continuous simulation of musculoskeletal diseases.

Musculoskeletal disorders show symptoms of pain and dysfunction caused by accumulation of minute damage on nerves and blood vessels which are related to specific body parts. This is more likely to occur in the elderly. In Korea, 40.3% of the agricultural population is over 65 years old. In these cases, the portion of musculoskeletal disorders is more than 80% in acute/chronic diseases related to agricultural work. Therefore, measures for physical health care and safety prevention of elderly farmers are needed. In this study, we intend to propose a method to measure musculoskeletal health condition through the motion recognition device and VR contents. For this, we analyze the agricultural work causing musculoskeletal disorders of farmers, and suggest a motion analysis algorithm that can measure the health condition of the musculoskeletal system. In addition, we are going to propose a training method customized for farmers on the basis of VR contents in order to prevent musculoskeletal disorders.

The Musculoskeletal Disease has been ignored or turned away due to the difficulty of diagnosis and the vagueness of judgement up to now. Contrary to other diseases, there were many cases where the character of the Musculoskeletal Disease wasn't revealed through the objective inspection. And that's because the Musculoskeletal Disease appears for the most part due to muscular defect so it is impossible to diagnose the muscle by X-ray diagnosing the bone and it is also impossible to diagnose the fine damage of the muscle or tendon even by advanced device like MRI. As the nervous blood vessels or acupunctures pass through or are next to the muscle, the tension of the muscle put pressure on these so can become the direct or indirect causes of various kinds of pains or intern diseases. But in spite of that, for lack of proper equipment diagnosing the state of the muscle(Shortened.. Relaxed... or Hardened...) the muscle has been disregarded or neglected intentionally or unintentionally. While many people think themselves to be a muscular expert, if they don't see the shape of the muscle, that is just like blind treatment. But as now the equipment diagnosing the state of the muscle is developed, it seems that this problem can be settled. It was attempted in this study that the muscle or skeleton of the Musculoskeletal disease patients was diagno the treatment order and method were decided by a questionnaire survey and simple inspection, and the Musculoskeletal correction exercise using the muscle management and sling system made them escape from the Musculoskeletal disease, turning their muscle into more flexible and stronger muscle. As a result notwithstanding the limited treatment period '12 times', the improvement rate was as high as 74%, which showed that the muscle management and Musculoskeletal correction exercise had a great effect on the symptom improvement of the patients. If the treatment times had increased, the improvement rate also would have increased more.

Objectives: The purpose of this study was to investigate the current trends in research on pharmacopuncture in Korea since 2007. Methods: A literature review was performed by using the search engines 'Science and Technology Society Village', 'Korean Studies Information Service System', 'National Discovery for Science Leaders', and 'Oriental Medicine Advanced Searching Integrated System' in Korea from January 2007 to December 2013. Searched key words were 'pharmacopuncture', 'herbal acupuncture', 'aqua-acupuncture', and 'bee venom'. Finally, we selected 457 papers, including Korean experimental studies and clinical studies. Selected papers were classified according to year of publication, type of pharmacopuncture, disease & topic, research type and the publishing journal. Results: One hundred fifty pharmacopunctures were studied in 457 papers. Single compound pharmacopuncture was the most studied pharmacopuncture in experimental studies while animal-based pharmacopuncture was the most studied pharmacopuncture in clinical studies. Bee venom placed first among the various pharmacopunctures, followed by placenta, sweet bee venom, mountain-ginseng, and anti-inflammatory pharmacopunctures. Experimental research on pharmacopuncture has fallen since 2007 when 55 papers were published. However, clinical research has been increasing steadily. In clinical studies, case reports were numerous than randomized clinical trials (RCTs). Musculoskeletal diseases were the most frequently-treated diseases in studies on pharmacopuncture; among the musculoskeletal diseases, rheumatoid arthritis was the most frequently-treated disease in experimental studies and low back pain was the most frequently-treated condition in clinical studies. Since 2007, 45 different journals have published studies on pharmacopuncture, with the Journal of the Korean Acupuncture and Moxibustion Medicine Society having the largest number of papers on pharmacopuncture and the Journal of Pharmacopuncture the second largest number. Conclusion: The trends in research on pharmacopuncture published in studies from 2007 to 2013 were similar to those in studies published before 2006. Many studies on pharmacopuncture focused on bee venom and musculoskeletal diseases. Additional studies on diverse types of and indications for pharmacopuncture are needed.

In order to conduct a study on the importance of the wrist joint, which causes a lot of pain among middle-aged people, in relation to work related to musculoskeletal disorders, the effect of stretching on grasping power was studied. In order to compare the grasping power of the wrist for middle-aged people in their 50s, the experiment was conducted by comparing before and after the wrist joint motion stretching. According to the experimental results of wrist gripping power for the control group and the experiment group on wrist gripping power, it was investigated that stretching did not change much in increasing wrist gripping power, but stretching application had an effect on wrist gripping power. In terms of preventing musculoskeletal accidents, reducing pain due to degenerative diseases, and preventing accidents, stretching seems to have an effect when approaching, so it is considered that continuous stretching before and after work is necessary. Therefore, it is suggested that stretching time secured quantitatively through safety and health education before work is necessary.

Purpose: This study was conducted to analyze the characteristics of work-related musculoskeletal diseases (MSD) and the factors for approving MSD by the parts of the body. Methods: The analysis was done using the data which were drawn from the Industrial Accident Compensation Insurance that is operated by the Korea Worker's Compensation & Welfare Service. The data were composed of total cases related to the work-related diseases from 2006 to 2009. In addition, MSD data input by an investigator were collected. The factors associated with MSD were analyzed using ${\times}2$ and multiple logistic regression. Results: MSD approved cases have increased since 2006 and the proportion of the approved work-related MSD cases in the workers with work-related diseases in 2009 were 33.4%. Spinal approved cases were the highest percentage and upper and lower extremities cases gradually increased. The factors for approving upper extremity were found to be age, company size, type of industry, working duration, and in the case of spine to be company size and heavy lifting. Conclusion: Work-related MSD have increased and the factors that affected MSD by the parts of the body varied. Management strategy must be established to prevent MSD by the parts of the body.

Objectives : This study is on the acupuncture and moxibustion treatment records of King Hyeonjong, classified according to diseases and chronology. Methods : Records on the acupuncture and moxibustion treatment of King Hyeonjong have been extracted from the web database of "The Daily Records of Royal Secretariat of Chosun Dynasty". First, all articles containing the keywords 'Yakbang (藥房)' and 'Euigwan (醫官)' have been extracted. Then, those during King Hyeonjong's reign have been rearranged in chronological order. Among these records, those regarding acupuncture and moxibustion have been used in this paper. Results : King Hyeonjong was mostly treated on eye diseases, musculoskeletal system disorders, deficient source qi, and tumor. Acupuncture treatment was preferred for eye diseases, and moxibustion treatment for musculoskeletal disorders. Medicine was used 50 times, acupuncture 4 times, and moxibustion 14 times to treat source qi deficiency, showing that acupuncture and moxibustion treatments were used for clear deficiency syndrome. Only on the case of tumor, the number of acupuncture treatments was bigger than that of medicine treatments. Conclusions : In the early days of his reign, King Hyeonjong suffered from hypochondria, as compared to source qi deficiency and septicemia during later days. He received frequent acupuncture and moxibustion treatments, and he especially preferred those treatments for eye diseases and musculoskeletal disorders.
