Safety is the most important issue in the construction industry. Especially, work-related disease is increasing and resulted in lack of young workers and high turnover due to its 3D industrial image. The main objective of this paper is to identify the relationship of WRMSD with hand tools used in the building construction industry. In order to reach to the goals, the survey and interviews with laborers are conducted. The data is analyzed in a statistical manner. One of the interesting findings from the research is that the carpenters and steelworkers are the principal trade group suffering from WRMSD due to unsafe working condition and method. The results of the research will be used as the basis for the ergonomic design of the better construction working condition and hand tools.

In this paper, we propose a Mixed Reality based rehabilitation exercise solution with the goal of mitigating one of the most common chronic conditions among the elderly, musculoskeletal disorders. In modern society, as the number of elderly increases, more people engage in office work and engage in more sedentary activities. Due to repetitive work in the office, muscle strength decreases and this causes many difficulties in daily life. In this study, we developed a mixed reality based exercise platform to solve these chronic musculoskeletal diseases. VR is not appropriate for elderly because of dizziness. In addition, we developed a wearable sensor based on IMU and attached it to important parts of the upper body to motion tracking. We developed a algorithm synchronize to raw data from wearable sensor with in a vr avatar. Ederly can check in real time whether rehabilitation exercises are being performed accurately through the avatar.

This study aimed to investigate the effect of a lap board that was developed to prevent musculoskeletal disorders caused by the use of a computer mouse. Study participants were 10 college students in their 20s who did not have any musculoskeletal symptoms. We analyzed the difference in upper limb movements, electromyographic activity, task performance, and subjective discomfort between 2 conditions: use of a mouse with the lap board and use of a mouse placed on a desk. Results of behavior analysis showed that there was a significant difference between the 2 conditions in terms of the average angle of shoulder flexion, shoulder internal rotation, and forearm pronation(p< 0.05). However, electromyographic activity, task performance, and subjective discomfort showed no significant differences between the 2 conditions. When subjects used the mouse with the lap board, their upper extremity was located much closer to the torso than when they used the mouse placed on the desk. Six of 10 participating students preferred the lap board. We expect that advanced research on prevention of musculoskeletal disorders due to the use of the computer mouse will be conducted in the near future.

연구목적 : 수심 깊이에 따른 수중운동이 하지근력에 미치는 영향을 알아보고자 하는데 목적이 있다. 연구방법 : 신경근골격계 질환이 없는 여자 10명을 대상으로 하였고, 무작위로 수성 0.7m 그룹과 1.4m 그룹으로 배치하였다. 수중운동은 1회 40분, 주 3회 6주 동안 적용하였다. Ultrasound MyLab25(Esaote, Italy)를 이용하여 하지근육의 우모각과 밀도를 실험전과 후에 측정하였다. 연구결과 : 골격근 구조의 역학적 특성을 나타내는 우모각 변화를 비교한 결과 0.7m 그룹의 오른쪽 넙다리곧은근과 왼쪽 넙다리곧은근, 앞정강근 그리고 장딴지근에서, 1.4m 그룹의 오른쪽 앞정강근과 장딴지근, 왼쪽 넙다리곧은근에서 통계학적으로 유의한 차이가 나타났으나(p<.05), 수심 깊이에 따른 유의한 차이는 없었다(p>.05). 또한, 질적 특성을 나타내는 근육 영상 밀도 변화를 비교한 결과 0.7m 그룹의 오른쪽 넙다리곧은근, 장딴지근과 왼쪽 넙다리곧은근, 앞정강근, 장딴지근에서 1.4m 그룹의 양쪽 넙다리곧은근, 앞정강근, 장딴지근에서 통계학적으로 유의한 차이가 나타났고(p<.05), 특히 1.4m 그룹에서 현저한 증가를 보였으나 수심 깊이에 따른 유의한 차이는 없었다(p>.05). 결론 : 본 연구에서는 수심 차이에 관계없이 수중운동 후 근밀도와 우모각에 영향을 미치는 것을 확인할 수 있었다.

MRI plays a crucial role in bone marrow (BM) assessment, and has very high sensitivity in diagnosing marrow disorders. However, for radiologists who may not frequently encounter pediatric imaging, distinguishing pathologic BM lesion from normal BM can be challenging. Conditions involving the BM in pediatric patients, such as leukemia and metastatic neuroblastoma, often manifest with diverse musculoskeletal symptoms and may be diagnosed using musculoskeletal MRI examinations. Accurate interpretation of pediatric MRI requires not only an understanding of the normal composition of BM but also an awareness of age-related developmental changes in the marrow and familiarity with conditions that commonly involve pediatric BM. We aim to describe the composition of normal BM and outline the normal and abnormal MRI findings in pediatric BM. Additionally, we aim to present clinical cases of malignant BM disorders including leukemia, neuroblastoma metastasis, and other malignant BM disorders.
