산림작업은 비정형화된 작업 환경(날씨, 지형)에서 신체의 반복적인 동작 등으로 인하여 근골격계 질환에 취약하다. 특히, 조림목의 원활한 생장을 위해 실행하는 풀베기와 칡덩굴제거 작업은 여전히 많은 인력이 투입되고 있으며, 이 작업자세에 대한 인간공학적 평가가 필요하다. 따라서 본 연구에서는 OWAS (Ovako Working Posture Analysis System) 분석방법을 이용하여 예초기를 이용한 풀베기 작업과 낫·손톱을 이용한 칡덩굴제거 작업의 신체부담을 정량적으로 평가하였다. 또한 작업자세 위험도 지수(Postural risk index: PRI)를 통하여 산림작업의 위험 정도를 분석하였다. 풀베기와 칡덩굴제거 작업원에 대한 작업자세를 분석한 결과, 칡덩굴제거작업의 작업자세 위험성이 풀베기작업에 비해 통계적으로 더 높은 수준을 보였다. 칡덩굴을 제거하는 작업 과정 중에서 다리에서는 두 다리를 구부리는 자세와 무릎 꿇는 자세의 비율이 높게 나타나기 때문에 근골격계에 부정적 영향을 미치는 것으로 판단된다. 이 연구결과는 풀베기와 칡덩굴제거 작업원의 작업부하 및 근골격계 질환을 저감하는 기초자료로 활용될 수 있을 것으로 기대된다.

Objective: This study aims to analyze and evaluate fatigue in upper trapezius muscles of adults when inputting text on a smart phone, thereby examining the risk of cumulative trauma disorders in the musculoskeletal system of the upper extremity. Method: Forty-five healthy adults were divided equally into three groups: a smartphone group, a notebook group, and a desktop group. A surface electromyogram was placed on the upper trapezius muscle of each participant, after which they inputted text for ten minutes within an ergonomic setting; their side posture was recorded on video and analyzed. Results: The spectral edge frequency values for the smartphone group, as recorded from the upper right trapezius muscles on the surface electromyogram, showed a significant decrease(p<.05). Regarding the RULA, all three groups had results indicating "action level 2". Conclusion: All three groups had results indicating "action level 2" according to the RULA, which means that additional research on the posture of the participants while performing tasks is necessary, and their posture needs to be corrected. In particular, the smartphone group has the highest levels of fatigue in the upper trapezius muscles, suggesting that the task of inputting text on a smartphone is a high risk for causing cumulative trauma disorders.

Background: Musculoskeletal disorders (MSDs) in the health industry are quite common, however, there have only been a few studies regarding physiotherapists, while in Greece, there is an apparent lack of research and data. The aim of this study is to investigate MSDs experienced by physiotherapists in Greece, their causes and specific measures, and good practices followed. Additional emerging risk factors will be examined. Methods: A questionnaire of MSDs followed by individual and workplace characteristics was completed by 252 physiotherapists. It covered the major workplace categories such as public hospitals, private rehabilitation centers, and private practices. Results: Analysis indicated that 89% of the respondents had experienced a work-related MSD; 32.2% of those injuries occurred within the first 5 years of working. The most lumbered physiotherapists were those working as private practitioners and almost half of the injured respondents chose to work while injured. The most common measure taken to tackle work related MSDs was found to be physical therapy sessions. Job satisfaction and psychosocial issues were also identified as side-effects of the economic slowdown. Conclusion: Physiotherapists in Greece were found to suffer from MSDs; workplace musculoskeletal injuries were quite common but under-reported. The body parts most affected were the lower back, the upper back, the shoulders, and the neck. There was a strong correlation between the workplace setting and the number of MSDs. A well-defined occupational safety and health management system and strict administration steering were found to reduce MSDs. The economic slowdown experienced in Greece during the execution of this study placed additional pressure on physiotherapists.

The purpose of this paper is to investigate the development of mechanical projectile transfer system to prevent musculoskeletal problems in the firing test range. Prior to 2010, the projectile has been transferred from the worktable to the loading device of 155mm K9 fixed-type artillery by manual. Because the amount of firing test has been increased drastically since 2010, two types of mechanical projectile transfer system were developed to prevent musculoskeletal problems. The NIOSH lift equation and the working posture assessment system such as OWAS, RULA and REBA were used to evaluate the appropriacy of working weight and posture by manual transfer of projectile. The configuration and operation procedure of projectile transfer systems which were developed to improve work efficacy and to reduce the burden of manual transferring were described. The improvements were assessed by the number of processes, the tact time and the working posture assessment for operation of this system by comparing to the manual transfer of projectile.

One of the major requirements in preventing Work-related MusculoSkeletal Disorders(WMSDs) is to know definitely what vigorous exertion requirements are contained in a job. This requires improved job analysis tools which can accurately evaluate potentially harmful stresses to the musculoskeletal system. But to simply evaluate the level of stress at a joint, or in a muscle is not enough to motivate job changes. Therefore, the development of ergonomic evaluation tools for the jobs are important to ergonomics. The main objective is compared of the results that made by the ergonomic evaluation tools (e.g., BRIEF and RULA) in actually shoes manufacturing. These were developed in the foreign. So, it is priory needed to research of the ergonomics about Korean characteristic work by physiology and biomechanics.
