국내외의 근골격계질환에 대한 현황과 자료를 검토하였다. 국내의 자료는 지난 수년간 대학 연구소에서 수행한 유해요인조사 및 예방사업 과정에서 수집된 자료들이다. 제조업에서 서비스업에 이르는 다양한 업종의 현황을 비교하였다. 외국의 자료와 비교할 때 가장 큰 특징은 국내의 근골격계질환 자료는 발생건수에서도 실제 생산형장에서의 현황보다 축소되어져 있지만, 전체 산업재해나 직업병에서의 비율로 볼 때도 매년 그 발생 비율이 불안정하게 등락함으로서 아직도 국내

The purpose of this study was to compare the onset times of muscle activities and the order of muscle firing in erector spinae, multifidus, rectus abdominis and biceps brachii during perturbation between subjects with and without work-related chronic low back pain (LBP). Twenty-nine subjects, 14 with and 15 without LBP, participated in this study. The muscle responses were measured by surface EMG (electromyography) during perturbation in eye opened and eye closed conditions. The EMG onset times of the erector spinae, multifidus, rectus abdominis and biceps brachii were similar between groups in eye closed condition. But the onset times of the erector spinae, multifidus, rectus abdominis were significantly delayed in subjects with LBP in eye opened condition. The results provide an evidence for impaired feed-forward control of the trunk muscles in subjects with LBP. Further studies are needed to identify whether the impaired feed-forward control of the trunk muscles is the contributing factor to LBP.

It was investigated the current state of work-related musculoskeletal disorders (WMSDs), which is one of the major problems in occupational safety and health management. A survey was conducted for safety personnel serve in the enterprises located at two cities in Gyungbuk area, Gumi and Pohang where the major industrial complex reside. The goal of this study was to identify whether the category and scale of the enterprises affect the sort of hazard factors, occurrence rate, and countermeasures against WMSDs. The results from the survey indicated that there were significant differences in the level of recognition and counteracts for WMSDs among the enterprises subject to their categories and scales. On the basis of these results, it was considered a more efficient way of spreading proper ergonomic knowledge and skills to the industries that were coincided with the circumstances of individual enterprise.

Despite improved working environment with increased automation in industry, the nursing professions are subject to great deal of potential occupational risks, including chemical exposure, occupational stress, and musculoskeletal stress. In this study, we investigated the work-related Low Back Pains(LBPs) among hospital nursing profession by questionnaire survey. The results showed that over 89% of nursing personnel answered had experienced work-related LBPs. Among these personnel, patient handling caused more than 78% of the incidents occurring at work. This study will thus contribute as a basic reference to the hospitals and ergonomic practitioners for nursing profession training program development, facility and equipment redesign, and for guiding future research concerning prevention of this very important occupational health problem.

최근에 경제 발전과 인식의 변화에 따라 국내외적으로 직업병에 관련된 많은 연구가 진행되고 있으며, 그에 따라 상당한 성과도 발생되고 있다. 하지만, 선원들의 열악한 근무환경에 비해 승선근무에 따라 발생하는 직업 관련성 상병에 대해서는 체계적인 연구가 이루어지지 못하고 있으며, 사후(事後) 처리적인 보상에 관련된 연구들만 이루어지고 있는 것이 현실이다. 그래서 이 연구에서는 선원의 직업성 관련 상병에 대한 기초 조사를 근거로 하여 그에 대한 관련 법령 및 제도를 검토하였다. 그리고 선원의 상병 예방과 발병 후 신속하고 적절한 지원을 하기 위한 법적 개선점을 제안하고자 한다.
