Unlike production line works, construction work is non-repetitive in nature. In this study, a checklist was developed to characterize the ergonomic hazards of construction work. Eight existing checklists including OWAS, RULA, and REBA were integrated, and a new version was designed to include more postures of lower extremities. The analysis results obtained using the new checklist showed that manual materials handling (MMH) is the most common risk factor. About 62% of the MMH was done below the knee level or above the elbow level, and 22% was carried out with the trunk twisted more than 60°. The next risk factors were the works done with the knee bent or squatted, or with the shoulders abducted. It can be concluded that the new checklist is successful as a quick and easy tool for screening risk factors of construction works, although it is not capable of determining action levels. Further studies on validation of the checklist are expected.

The objective of this study was to establish a systematic ergonomic program for the prevention and control of work-related musculoskeletal disorders(WMSDs) in a machinery manufacturing company. The steps such as looking for the signs of WMSDs problems, setting the stage for action, training-building in-house expertise, gathering and examining the evidence of WMSDS, developing controls of health care management, and proactive ergonomic interventions were applied. The primary success factors were management commitment and encouragement, and harmonious union-management relations.

Objective: To develop a BARAW (By Avoiding Repetitive motions, Awkward postures and Weights) tool which can be applied to assess and improve the musculoskeletal discomfort and pain associated with nursing service workers. Background: Most of existing MSDs assessment tools were developed to investigate the repetitive works commonly found in manufacturing industry. A new approach is needed to assess such non-repetitive works as those done by nurses. Method: As the first step of developing BARAW tools, we investigated the existing assessment tools and guidelines for nurses. And then, BARAW tools were developed based on the results of the expert interview. Based on FGI (Focus group interview) and literature review, a questionnaire was developed to investigate the causes of the musculoskeletal discomfort and pain. Reliability of the questionnaire was tested. Results: The procedure of using the BARAW tool is as follows; 1) finding the cause of discomfort and pain 2) finding possible interventions, 3) implementation of the interventions, 4) evaluation of BARAW’s effectiveness, 5) feedback. Very high reliabilities were obtained from the test. Conclusion: It was shown that BARAW tool developed in this research is a readily applicable to the works of nurses. Application: BARAW tool could be extended to other non-repetitive works.
QFD와 불편도 실험을 통한 겨드랑 목발의 인간공학적 분석 및 디자인

The aim of this paper is to improve the design of a pair of axilla crutches through quality function deployment(QFD) and discomfort experiments. User needs for the crutches, as well as the engineering characteristics which have influence on the ergonomic quality of crutches were determined from the interview with many users. This information was entered in the house of quality, and the results show that the axillary pad and grip are the most important quality factors. And the results from the discomfort experiments confirmed the QFD output. A prototype reflecting the QFD results was proposed. The present study demonstrated how QFD approach can be a methodological tool geared to greater ergonomics consideration in product design.

Objective: This study aims to review the ergonomic literature about the musculoskeletal problems in fishing, and to suggest directions of further studies. Background: Until the 1960s, fishing was one of the dominant industries in the economy of Korea, but nowadays it is of little importance. However, the fishing industry should be sustained and the health of the people involved in the industry should be maintained and enhanced. Method: The peer-reviewed articles from international and domestic academic journals published after year 2000 were searched using Web of Science, Google Scholar, DBPia and KISS. The literature was searched by the keywords of "fishing", "fishery", "fishermen", "musculoskeletal", "ergonomic", "occupational", "injury", "health", and their combinations. Results: 20 international articles were analyzed. They could be classified into the descriptive studies on problem identification (8 articles, 40%), biomechanical or quantitative studies (4 articles, 20%), studies on the musculoskeletal symptoms (4 articles, 20%), development of intervention (2 articles, 10%), and literature review (2 articles, 10%) Only 2 domestic articles were found. Conclusion: It was confirmed that the musculoskeletal problems in fishing are prevalent and severe. More studies are expected on the ergonomic design of fishing vessels and machines/tools used in fishing work. Application: The results will be applied to guide the direction of further ergonomic research to lead the development of fishing industry.
작업자세와 작업시간을 고려한 농작업의 인간공학적위험성 평가 방법의 제안

Objective: A method to assess the risk level of agricultural works considering work posture and working time was suggested, and the method was applied to the major fruit crops. Background: It is not complete to analyze only work postures when assessing risk level of agricultural works. Method: $3{\times}3$ matrix was employed, in which the severity level was taken from the REBA method and exposure level was taken from the working time, using the criteria of caution zone/hazard zone. Results: Among the 5 major fruit crops(apple, pear, grape, peach, persimmon), the highest level of ergonomic risk was found in the apple and pear, while medium level was found in other 3 crops, mainly because the working time was less in the 3 crops. Conclusion: It was found that when assessing the overall ergonomic risk of agricultural works, work posture and working time should be considered at the same time. Application: The suggested method could be applied to other non-cyclic tasks.

Objective: In this research, the literatures on the autonomous vehicles were surveyed and classified from the viewpoint of human factors. Technological development on the information interaction between user and the vehicle was discussed. Background: The studies on the human factors in the autonomous vehicles have been less actively carried out than those on the technological aspects, but human factors are becoming more important in the autonomous vehicles. Method: This study examined the papers published in domestic journals, as well as the papers presented in conferences from 1996 to 2016 through DBPIA. Results: The literatures were classified into those about basic functions and convenience. The papers on the convenience were much less. Conclusion: Human factors are projected to be actively applied, in communication and in device control, in addition to conventional application areas. Application: This study would be of help to find future research areas of human factors in autonomous vehicles.

Work-related musculoskeletal disorders (WMSDs) are recognized as leading causes of significant human suffering, loss of productivity, and economic burdens on our society. WMSDs are associated with work patterns that include fixed or constrained body positions, continual repetition of movements, force concentrated on small parts of the body, cold environment and vibration. Main effort to protect workers from WMSDs should focus on avoiding repetitive patterns of work through engineering controls which may include mechanization, ergonomic design of tools and equipment, and workplace layout. Where elimination of the risk factors is not practical, administrative controls involving job rotation, job enlargement and enrichment, teamwork should be considered.
