  • 본 연구에서는 역사 내 철도 안전 감시 시스템의 최적 디스플레이 설계를 위하여 생태학적 인터페이스 디자인(EID, Ecological Interface Design) 프레임웍을 적용하였다. 특히, EID 개발을 위한 가장 선행적 연구인 작업 영역 분석(WDA, Work Domain Analysis)을 실시하였다. 먼저 WDA를 위한 시스템 경계를 도시철도의 역사 내 안전 감시 시스템으로 설정하고, Abstraction Hierarchy (AH)를 이용하여 역무원의 작업 환경을 분석하였다. AH 결과 역무원이 작업 환경에서 얻게 되는 정보의 흐름을 다섯 단계의 수준(Functional Purpose, Values and Priority Measures, Purpose-related Functions, Object-related Process, Physical Object)으로 전개할 수 있었고, 각각의 수준의 정보로 이루어진 작업 영역 모델(WDM, Work Domain Model)을 얻었다. 이 WDM이 도시철도 안전 감시 시스템의 작업 환경을 얼마나 반영하는지 평가하기 위하여 10년 이상의 역무실 직무 경험이 있는 전문가를 대상으로 Scenario Mapping법을 실시하였다. 평가된 WDM을 바탕으로 현재 역사 내 안전 감시 시스템이 제공하고 있는 정보는 물론이고, 현재 안전 감시 시스템이 제공해주고 있지 못하는 13개의 요구 정보를 추가로 추출하였다. 이렇게 추출된 요구 정보는 도시철도 안전 감시 시스템의 EID에 반드시 반영되어야 할 필수적인 정보로 활용될 수 있다.

  • Objectives: This study was conducted to examine the relationship between crude oil exposure and physical symptoms among residents participating in clean-up work associated with the Hebei Spirit oil spill, 2007 in Korea. Methods: A total of 288 residents responded to a questionnaire regarding subjective physical symptoms, sociodemographic characteristics and clean-up activities that occurred between two and eight weeks after the accident. Additionally, the urine of 154 of the respondents was analyzed for metabolites of volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs) and heavy metals. To compare the urinary levels of exposure biomarkers, the urine of 39 inland residents who were not directly exposed to the oil spill were analyzed. Results: Residents exposed to oil remnants through clean-up work showed associations between physical symptoms and the exposure levels defined in various ways, including days of work, degree of skin contamination, and levels of some urinary exposure biomarkers of VOCs, metabolites and metals, although no major abnormalities in urinary exposure biomarkers were observed. Conclusions: This study provides evidence of a relationship between crude oil exposure and acute human health effects and suggests the need for follow-up to evaluate the exposure status and long-term health effects of clean-up participants.

  • Objective: The objective of this study was to evaluate a work of guards, using an ergonomic method(work analysis and posture analysis). Background: Most studies about guards were conducted in the field of medical, problems of shift, and the physical problems of old workers and social problems. But, guards consist of vulnerability group so it needs an ergonomic research in musculoskeletal disorders. Method: A head of an ergonomic estimation was work analysis(determination of combined task, work tool, work time and frequency of combined task) and posture analysis(upper body and lower body) of workers based on the video. Results: The result showed that combined task of guards was classification of patrolling, security, cleaning and waiting. The security indicated the highest ratio in the work time of combined tasks. The results of posture analysis for guards indicated high value in neutral. But, lower arm indicated high value in bending(left: 59%, right: 50%). Conclusion: The results of ergonomic methods indicated that guards' physical work load was not high during work, but comfortable work environment would be required for old guards. Application: If an ergonomic rule can be integrated into existing work environments, the risk of occupational injuries and stress will be reduced.

  • Background: Employee job satisfaction and its relationship with health and quality of life has been an issue of major concern over the past decades. Nurses experience difficult working conditions that affect their job satisfaction, health, and quality of life. Methods: A cross-sectional study was undertaken in three general hospitals and their respective health centers. Stratified random sampling by level of education was used, and 508 nurses and nursing assistants were included. A self-administered anonymous questionnaire, which included the Measure of Job Satisfaction, the 36-item Short Form Health Survey, as well as demographic details, education, and work conditions data, was used. Results: Greek nurses were found to be dissatisfied with their job according to the total score of the job satisfaction scale, although personal satisfaction and satisfaction with support had had higher scores. Their general health was reported as average, because of physical and mental health problems, low vitality, low energy, and increased physical pain. Multivariate linear regression analysis revealed that males and those wishing to stay in the job had higher physical and mental health. Increased job satisfaction was related to increased physical and mental health. Conclusion: Although Greek nurses are not satisfied with their work, those with high levels of job satisfaction had better health-related quality of life. The findings suggest that improvement of the work environment would contribute to a healthier and more satisfied nursing workforce.

  • Background: The aim of this study was to investigate which physical and psychosocial work demands were associated with excellent work ability in individuals with neck pain, and to investigate age and sex differences in these associations. Methods: The study sample was obtained from the Statistics Sweden cross-sectional Work Environment survey and consisted of workers who reported neck pain after work (N = 3,212). Results: The findings showed an association between excellent work ability and self-reported low exposure to lifting, twisted work posture, working with hands in shoulder level or higher, and leaning forward without support and combination of exposures containing these work demands. Low exposure to seated work and high demands showed a reversed association. The associations were present mainly among older workers and were generally stronger for men than for women. Conclusion: This study indicates that a lower level of physically demanding work is an important element to maintain excellent work ability, especially for the older worker with neck pain.

  • Objective: The objective of this study was to evaluate a work of building cleaners using the ergonomic methods. Background: Previous studies about cleaning worker describe typical physical demands of this work. They found that the most significant risk factors associated with the physical work of cleaners are static loads and repetitive movements and high output of force. Method: A head of ergonomics estimation was work analysis(define of combined task, work tool, work time and frequency of combined task) and posture analysis of worker. Results: The results showed that combined task of building cleaners was classification sweeping, mopping(wet), mopping(oil), moving barrels/carts, dumping trash bags, scrubbing, arrangement of cleaning tool, arrangement of circumferential, moving of cleaning tool, and waiting. The work time of combined task such as mopping(wet) and scrubbing indicated high ratio. The posture analysis of building cleaners indicated high value in bending of the head, lower arm, and hands. Conclusion: The findings appear to indicate that building cleaner were related to high risk of work-related musculoskeletal disorders. So, building cleaner would be required an interventional strategy, improvement of cleaning tools and working environment. Application: If ergonomics rule can be integrated into existing cleaning tools and work environments, the risk of occupational injuries will be reduced.

  • The purpose of this study was to explore the concepts of health among people with mobility disabilities in order to develop a new holistic model of health and to identify implications for social work practice. A qualitative study based on face-to-face interviews with people with mobility disabilities was conducted. Nine consumers and nine social workers with mobility disabilities participated in the study. Social constructionism, heuristic paradigm, empowerment paradigm, and strength perspectives were used to form conceptual foundations to guide the study. Study participants' holistic descriptions of the concept of health encompassed five domains: biological/physical, mental/emotional, financial, relationships with others, and spiritual. Participants described health as harmony among these five domains. Harmony indicates that all five domains contribute to the concept of health, and that each domain is related to the others. Participants also viewed disability and health as an interconnected whole, not separate concept. The conceptual model developed in this study expands on the existing concepts of health by considering multiple factors at the personal and environmental levels, as well as interactions among the factors and between the levels. The personal level has five domains: biological/physical, mental/emotional, spiritual, financial, and relationships with others. The environmental level has also five domains: relationship with others, financial, social programs, social attitudes toward peoplewith disabilities, and physical environment. All factors under the personal and environmental levels also affect each other. The holistic concept of health for people with disabilities is not solely a part of the person, but rather is a function of the interaction between the person and their environment. The study demonstrated that people with disabilities have strength and resiliency, and health is an attainable goal for them, particularly when environmental and cultural barriers are addressed. The focus of social work practice should be the removal of those barriers encountered by their consumers with disabilities, as well as, the enhancement of internal factors that facilitate well-being.

  • The hand is a very specialized organ that functions to obtain information and to execute motor acts essential to human interaction with the environment. Loss of hand function through infections affects the mechanical tasks that the hand performs and psychological adjustments to their disability. Infection is a disastrous complication of hand injuries and adequacy of circulation is of greatest importance to prevention of infection. Careful debridement, incision, and adequate drainage and antibacterial treatment are of great importance. Optimal care of the infected hand demands that carefully surgical care, early postoperative exercises and other therapy. Hand rehabilitation has grown as a specialty area of both physical and occupational therapy. It is essential that the surgeon and therapist work together, and communicate freely-all of which generally require daily contact. Treating the psychological loss suffered by the patient with a hand infections is an integral part of the rehabilitation therapy as well. Treatment techniques, Whether thermal modalities or specifically designed exercises, are used as a bridge to reach a further goal of returning to functional performance.
