Objectives: The objective of the present study was to assess the factors that influence the health of workers, especially nurses, and to propose methods for health management. Methods: A total of 246 nurses were surveyed to ascertain the health status score, Sasang constitution diagnosis, health-related life and job factors, psychosocial stress, and job stress. Depending on their health status score, the subjects were categorized into unhealthy, intermediate, or healthy groups, and each factor was compared with the stress score of the groups. Further, each Sasang constitution factor was also compared with the stress scores. Results: Analysis based on the health status scores indicated that the patients in the intermediate group were older and had longer tenure than those in the unhealthy or healthy groups. The healthy group had higher number of married individuals, and they were subjectively assessed as healthy. Patients in this group were more satisfied with their work than those in the unhealthy group. Analysis of the Sasang constitution showed that a lower percentage of individuals with a Soeumin constitution were married, and most considered themselves to be unhealthy during the subjective health assessment. Conclusions: The findings of this survey revealed that in order to maintain health, efforts should be made to improve the work environment, achieve health confidence, and practice health behavior while considering one's own body, mental state, and constitution.

Background: Effort-reward imbalance (ERI) and overcommitment at work have been associated poorer mental health. However, nonlinear and nonadditive effects have not been investigated previously. Methods: The association between effort, reward, and overcommitment with odds of poorer mental health was examined among a sample of 68 formal United States waste workers (87% male). Traditional, logistic regression and Bayesian Kernel machine regression (BKMR) modeling was conducted. Models controlled for age, education level, race, gender, union status, and physical health status. Results: The traditional, logistic regression found only overcommitment was significantly associated with poorer mental health (IQR increase: OR = 6.7; 95% CI: 1.7 to 25.5) when controlling for effort and reward (or ERI alone). Results from the BKMR showed that a simultaneous IQR increase in higher effort, lower reward, and higher overcommitment was associated with 6.6 (95% CI: 1.7 to 33.4) times significantly higher odds of poorer mental health. An IQR increase in overcommitment was associated with 5.6 (95% CI: 1.6 to 24.9) times significantly higher odds of poorer mental health when controlling for effort and reward. Higher effort and lower reward at work may not always be associated with poorer mental health but rather they may have an inverse, U-shaped relationship with mental health. No interaction between effort, reward, or overcommitment was observed. Conclusion: When taking into the consideration the relationship between effort, reward, and overcommitment, overcommitment may be most indicative of poorer mental health. Organizations should assess their workers' perceptions of overcommitment to target potential areas of improvement to enhance mental health outcomes.

Background: This study aimed to investigate the relation between key strike forces and musculoskeletal symptoms (MSS). Moreover, this study presents a key strike force measurement method to be used in a workplace setting. The correlation between key strike force characteristics and MSS was previously studied, but the measurement methods used either a single-key switch or force platforms applied under the keyboard. Most of the studies were conducted in a laboratory setting. The uniqueness of measurement methods in the current study is their ability to measure forces applied to a specific key in a workplace setting and to provide more information about specific key strike forces during typing. Methods: Twenty-four healthy computer workers were recruited for the study. The demographic questionnaire, and self-reported questionnaires for psychosocial status (General Nordic Questionnaire for Psychological and Social Factors at Work) and for detecting MSS were filled up, which later helped in dividing the participants into two groups (12 participants with pain and 12 without pain). Participants typed a predetermined text that utilized the instrumented keys multiple times. The dynamic forces applied to the keys were recorded and collected, using four thin and flexible force sensors attached to the preselected keys according to their location. Results: The results demonstrated that participants with high levels of MSS, specifically in the back and neck, in the last year exerted significantly higher key strike forces than those with lower levels of symptoms (p < 0.005). Conclusion: The key strike force exerted while typing on a keyboard may be a risk factor for MSS, and should therefore be considered in ergonomic evaluations and interventional programs.

본 연구는 6개월 이상의 만성 비치성 구강안면통증(orofacial pain, OFP) 환자들을 대상으로 통증으로 인한 사회심리적 영향을 평가하고, 대학병원의 구강안면통증 전문클리닉에 내원한 OFP 환자들의 임상적 특성(유발사건, 이전 치료병력 등)을 조사하고자 하였다. 연구를 위하여 2008년 9월부터 6개월간 단국대학교 치과대학 부속 치과병원 구강내과 구강안면통증클리닉에 내원한 초진환자 중 OFP 환자들의 초진시 진료기록과 면담 전 대기실에서 작성한 만성통증척도(Graded Chronic Pain Scale, GCPS) 설문지를 조사분석하였다. 본원에 지난 6개월간 내원한 다양한 비치성 구강안면통증 572 명의 환자들 중 63%는 이전 치료 경험이 있었고 약물치료, 상담, 물리치료의 순으로 빈도가 높았고, 전문과목은 일반치과와 정형외과의 순서였다. 환자들의 89.2%는 턱관절장애였고 6.4%는 삼차신경통을 포함한 신경병성동통, 4.5%는 2가지 이상의 OFP가 공존하는 복합성 안면통증(mixed OFP)이었다. 통증의 발생과 관련한 유발요인에 대해서는 환자들의 약 35%가 인지하고 있었으며, 외상, 치과치료의 순으로 빈도가 높았다. OFP 환자의 약 반 정도(46%)는 만성 통증을 가진 환자였으며, 이 중 40%에 이르는 많은 환자들이 구강안면통증으로 인하여 일상적인 활동과 사회적 활동 및 업무능력에 상당히 제한(high disability)을 받는다고 보고하였다. 여성일수록, 나이가 많을수록, 통증병력이 길수록(>5년) 그리고 턱관절장애보다는 신경병성 통증과 복합성 구강안면통증 환자들이 더 심한 사회심리적 활동제한을 보였다.(p=0.000) 이러한 연구결과는 환자가 자신의 만성통증에 수반되는 사회적, 심리적 장애(disability)를 잘 이해할 수 있도록 사회심리적 지원이 필요하며, 가능한 한 조기에 전문가에게 내원하여 정확한 진단을 받을 필요가 있음을 보여준다.

Objective: This study aims to survey the prevalence of musculoskeletal disorders(MSD) among Korean hospital workers and to analyze the relationship of MSD symptoms and workload perceived by workers. Background: Despite of high exposure to the MSD risk factors and high MSD symptom prevalence among health care workers, there were not enough studies of MSD prevalence among the hospital workers. Method: This study designed a survey based on Nordic questionnaire to obtain MSD symptoms and the degree of four perceived workloads: work repetition, urgency, physical exertion and satisfaction. In this survey, 1,846 workers in a hospital participated. The prevalence of MSD was analyzed for each body part, and MSD cases, which were predetermined in this study, were identified. The relationship between the MSD cases and each perceived workload was analyzed using chi-square test. Results: The pain in the shoulder was the most prevalent among the workers as 52%, and the low back(37%) and leg discomfort(36%) followed. The MSD cases, in which degree of pain was more than severe, were also the most prevalent in the shoulder(13%). Female workers had higher rate of MSD cases than the males. Among the four workload variables, the physical exertion was the statistically related to MSD cases for all the body parts. In addition, the others also had significant relation to MSD cases except one or two body parts. Conclusion: This study found that Korean hospital workers had MSD symptoms mainly in the shoulder, low back and legs in order, and the perceived workload surveyed in this study was highly correlated with MSD symptoms. Application: This study provides another evidence that subjective physical exertion perceived by workers is an important factor to explain MSD cases as same as the objective one.

Objective: The purpose of this research was to assess the agreement between job physical risk factor analysis by ergonomists using ergonomic methods and physical examinations made by occupational physicians on the presence of musculoskeletal disorders of the upper extremities. Background: Ergonomics is the systematic application of principles concerned with the design of devices and working conditions for enhancing human capabilities and optimizing working and living conditions. Proper ergonomic design is necessary to prevent injuries and physical and emotional stress. The major types of ergonomic injuries and incidents are cumulative trauma disorders (CTDs), acute strains, sprains, and system failures. Minimization of use of excessive force and awkward postures can help to prevent such injuries Method: Initial data were collected as part of a larger study by the University of Utah Ergonomics and Safety program field data collection teams and medical data collection teams from the Rocky Mountain Center for Occupational and Environmental Health (RMCOEH). Subjects included 173 male and female workers, 83 at Beehive Clothing (a clothing plant), 74 at Autoliv (a plant making air bags for vehicles), and 16 at Deseret Meat (a meat-processing plant). Posture and effort levels were analyzed using a software program developed at the University of Utah (Utah Ergonomic Analysis Tool). The Ergonomic Epicondylitis Model (EEM) was developed to assess the risk of epicondylitis from observable job physical factors. The model considers five job risk factors: (1) intensity of exertion, (2) forearm rotation, (3) wrist posture, (4) elbow compression, and (5) speed of work. Qualitative ratings of these physical factors were determined during video analysis. Personal variables were also investigated to study their relationship with epicondylitis. Logistic regression models were used to determine the association between risk factors and symptoms of epicondyle pain. Results: Results of this study indicate that gender, smoking status, and BMI do have an effect on the risk of epicondylitis but there is not a statistically significant relationship between EEM and epicondylitis. Conclusion: This research studied the relationship between an Ergonomic Epicondylitis Model (EEM) and the occurrence of epicondylitis. The model was not predictive for epicondylitis. However, it is clear that epicondylitis was associated with some individual risk factors such as smoking status, gender, and BMI. Based on the results, future research may discover risk factors that seem to increase the risk of epicondylitis. Application: Although this research used a combination of questionnaire, ergonomic job analysis, and medical job analysis to specifically verify risk factors related to epicondylitis, there are limitations. This research did not have a very large sample size because only 173 subjects were available for this study. Also, it was conducted in only 3 facilities, a plant making air bags for vehicles, a meat-processing plant, and a clothing plant in Utah. If working conditions in other kinds of facilities are considered, results may improve. Therefore, future research should perform analysis with additional subjects in different kinds of facilities. Repetition and duration of a task were not considered as risk factors in this research. These two factors could be associated with epicondylitis so it could be important to include these factors in future research. Psychosocial data and workplace conditions (e.g., low temperature) were also noted during data collection, and could be used to further study the prevalence of epicondylitis. Univariate analysis methods could be used for each variable of EEM. This research was performed using multivariate analysis. Therefore, it was difficult to recognize the different effect of each variable. Basically, the difference between univariate and multivariate analysis is that univariate analysis deals with one predictor variable at a time, whereas multivariate analysis deals with multiple predictor variables combined in a predetermined manner. The univariate analysis could show how each variable is associated with epicondyle pain. This may allow more appropriate weighting factors to be determined and therefore improve the performance of the EEM.
