  • The purpose of this study was to identify the observable symptoms of musculoskeletal disease from electronic components manufacturing workers who involved in many repetitive tasks and to provide the basic data for the prevention and management. The survey was conducted on 721 people from 15 April, 2013 to 17 May, 2013 by self­recording type. The results of the study are as follows. First, symptom complaints based on different body parts are in following order, waist was 12.9%, shoulder was 10.5%, neck was 7.4%, hand/wrist/finger was 7.4%, leg/foot was 4.4%, arm/elbow was 2.8%, and 21.9% of the respondents showed symptoms in more than one body part. Sex, age, marital status, work experience, work intensity, and past accident experience were statistically significant. Second, in the job stress evaluation, all male and female workers were below the median of Korean workers in all of 8 categories. the higher the scores for lack of job autonomy, the higher the symptom complaints of musculoskeletal disease. In the case of patients complain observable symptoms of musculorskeletal disease, they should receive proper outpatient treatment, various programs such as stretching by body parts, setting up a desirable working posture, switching to cyclical work, should b developed as much as possible.

  • Purpose: The present study examines symptoms of VDT syndrome perceived by those nurses reviewing the application of health insurance at hospitals. This study also investigates those factor influencing on the experience of VDT syndrome among those nurses. Method: Data were collected through mail questionnaire survey in April, 2003. Of the 250 questionnaires disseminated, 214 questionnaires were finally analyzed using descriptive statistics and multiple regression analysis through SPSS/PC version 10.0. Result: Of the VDT syndrome, the musculoskeletal symptom score was highest, followed by ophthalmologic symptoms. The musculoskeletal symptoms were higher among younger nurses, having smaller space under the desk, and feeling uncomfortableness of the chair. The ophthalmologic symptoms were higher among those with a bachelor's degree, younger nurses, and those having a light reflection on the computer monitor, and those maintaining less than 40cm between eyes and the monitor. Higher dermatologic symptoms were observed among younger nurses and those using unclear monitor. The psychological symptoms were higher among younger nurses, those having a light reflection on the monitor, those unable to control the height of their chair, and those using uncomfortable chair. The overall symptoms were higher among younger nurses, those having a light reflection on the monitor, and those smaller space under the desk. Conclusion: Primary intervention should be given to those nurses with symptoms of VDT syndrome in order to regain health and prevent further aggravation of the symptoms. In particular, self-care behaviors of the nurses using VDT should be promoted with administrative support.

  • Fire service personnel and ambulance paramedics suffer musculoskeletal disorders as they lift and carry patients while performing Emergency Medical Services (EMS). The objective of the current study was performed to examine the association between working environment and musculoskeletal disorders of 119 paramedics and to analysis the EMS activities for them through basic survey (including task characteristics, risk factors, symptoms and illnesses). Observational job analysis of EMS activities indicated the squatting posture during first-aid performed on floor and the abrupt use of force during carrying heavy load including stretcher with patients on as hazard factors, and excessive low back twisting and bending during stairway transfer was observed. In addition, work-physiological assessment revealed various but rather high lumbar muscle usage rate among the study subjects, being 14.6~32.8% compared with Maximum Voluntary Contraction (MVC) during patients transfer work. Resting heart rate showed 65/min, on the other hand, heart rate on mobilization indicated maximum 124~156/min. Therefore, the results of analysis to the EMS activities, rescuer activities and medical tasks were accompanied with high possibility of accident and musculoskeletal disorders. Also, EMS activities indicated high muscle fatigue and energy consumption, and accumulated muscle fatigue with during continued work.

  • In this study, the authors introduced DASH (Disabilities of the arm, shoulder, and hand), which had been developed for evaluating the functional impairment in the movement of upper extremities in regular daily activities, work ability and sports/performing arts ability. It is an ergonomic risk assessment tool used for industrial workers and also a disability measurement tool for upper extremity disorders arising from musculoskeletal disorders and symptom. This study intended to examine the applicability of DASH in occupational health field. Firstly, DASH development process and composition were reviewed through The DASH outcome measure user's manual and early articles. Secondly, reliability, validity, and responsiveness of the DASH in various languages at the application stage as well as its reliability and validity at the early stage of development were investigated. Thirdly, focusing on the application of DASH to clinical cases, workers with musculoskeletal symptoms, healthy workers, workers with other diseases, and general population were discussed besides workers with major musculoskeletal disorders. Lastly, DASH questionnaire was examined for its potential as a reference for assessing the functional impairment in the movement of upper extremities of workers with musculoskeletal symptoms in industrial workers in Korea.

  • Purpose: This was integrative literature review for analyzing interventions of musculoskeletal symptom and pain on nurses. Methods: Data were searched by using databases, namely SAGE journals, EBSCOhost, PubMed, RISS, NDSL and KCI Search terminology included nurse and musculoskeletal and the language was Korean or Engli.sh. Data analysis was classified by risk of bias, inconsistency, indirectness and imprecision. Total six studies, one Korean and five English articles analyzed. Results: Risk of bias was serious in three of six studies. Regarding inconsistency, one study was moderate effect size and two studies were small effect size. There was no serious indirectness except one study. Regarding imprecision, three studies were not serious. Conclusion: Evidence from six studies was insufficient to support intervention's effect in means of no repeated studies and no high effect size of intervention. Evidence-based interventions must be applied on nurses for reducing musculoskeletal symptoms.

  • To prevent the musculoskeletal diseases from repeated dental treatment, the health status and subjective symptom according to the working environment of dental hygienists were examined in 185 Gyeongnam dental hygienists from October 01, 2017 to October 30. The health status of the study subjects (χ2=40.21, p<.001), the physical burden of work (χ2=47.68, p<.001) and the mental fatigue of work (χ2=66.98, p<.001) were significantly different according to working experience. The level of mental fatigue depended on the number of dental hygienists in the clinics (p=0.032). 94.1% of the subjects knew musculoskeletal diseases and there were significant differences according to working experience (χ2=77.85, p<.001), the numbers of patients in a day (χ2=41.08, p<.001) and daily standing time (χ2=6.96, p=.008). Currently, 73.0% of the dental hygienists have musculoskeletal diseases. There was a significant difference according to the number of patients (χ2=51.01, p<.001) and daily standing time (χ2=25.15, p<.001). The presence of injured parts due to musculoskeletal disorders showed a significant difference according to the numbers of patients (χ2=18.98, p<.001) and daily standing hours (χ2=33.20, p<.001). The musculoskeletal diseases examination of dental hygienists is needed based on subjective symptoms of musculoskeletal diseases and prevention and management of measures musculoskeletal diseases are required.

  • Objectives: The aim of this study was to determine the prevalence of symptoms relating to musculoskeletal disorders (MSDs) and investigate the risk factors among researchers at university laboratories. Methods: 209 researchers were included in this study, drawn from 27 laboratories at three universities in Korea. Checklists for MSD symptoms and risk factor assessment were utilized. Results: The symptoms checklist showed reliable results with Cohen's Kappa 0.33-0.56, percent agreement 81.0-96.8%, and correlation coefficient 0.41-0.63. The overall prevalence of MSD symptoms was 68.9%, while the prevalence in specific parts of body were as follows: shoulders (47.6%), lower back (46.9%), neck (46.9%), knees (25.4%), wrists (20.1%), elbows (13.6%). The symptom prevalence among women was higher than among men (OR 2.67, 95% CI 1.37-5.18). Daily exposure time was observed to be a significant risk factor for developing MSD symptoms (OR 2.14-6.07). Conclusions: This study suggested that repetitive pipetting and static work posture are the most significant risk factors for MSD symptoms among laboratory researchers.

  • 본 연구는 Rapid Upper Limb Assessment(RULA)를 이용하여 자동차 조립작 업에 대한 인간공학적 작업평가를 하고, 이 결과와 작업관련 상지 근골격계 질환의 자각증상율 및 작업특성 변수들의 연관성을 분석함으로써, RULA결과가 관련 신체부위의 통증이나 불편함으로 보고되는 근골격계 부하의 좋은 지표가 될 수 있는지, RULA평가체계를 이용하여 작업 위험도가 적합한지 여부를 평가할 수 있는가를 보고자 하였다. 자동차 제조업 작업자 314명을 대상으로 근골격계질환 자각증상설문과 RULA를 이용한 작업평가를 하였으며, 다음과 같은 결과를 얻었다. 1. NIOSH의 작업관련 근골격계 질환의 감시기준(surveillence criteria)에 따라 자각증상을 조사한 결과, 연구대상자 중 목 32.8%, 어깨 26.4%, 팔 10.5%, 손 29.3%, 허리 41.4%였으며, 한가지 이상 의 증상을 보이는 경우는 62.4%의 분포를 보였다. 2. 품질관리부에 비해 조립부서 작업자 틀이 전체 증상과 어깨, 허리, 팔 및 손부 위 증상에서 더 높은 유증상률을 보였다(p<0.05). 3. 부서별 RULA를 이용한 작업평가 결과, 서브/조립반과 의장반의 공정이 높은 위험점수를 보였다. 전체 조립부서에 대한 평가결과 적합한 작업은 3.02%였고, 62.8%가 부적합한 작업으로 작업전환이나 중재조치가 필요한 경우였다. 자각증상과 RULA를 이용한 작업평가 결과를 비교한 결과 RULA점수가 클수록 자각증상율이 높음을 보였다.(p<0.05) 4. RULA평가지표와 자각증상사이의 관련성을 보기 위하여, RULA지표와 기타 작업관련요인들을 독립변수로, 자각증상유무를 종속변수로 하여 다중 로지스틱 회귀분석을 실시하였다. 최종적으로 증상유무를 가장 잘 설명하는 회귀모형에 대한 분석결과는 다음과 같다. 모든 증상군에 대해서는 반복작업(OR 2.183), 진동공구 사용(OR 2.775)과 총 위험도 점수(OR 2.250); 목 부위 증상군에서는 상완의 자세점수(OR 1.786), 상완 및 손부 위의 총점수(OR 1.634) ; 어깨 증상군은 상지의 근사용(OR 3.076), 상완 및 손부 위의 총점수(OR 1.798); 어깨와 목 부위를 합한 증상군은 상완 및 손부위의 총점 수(OR 1.715)와 상지의 근사용 점수(OR 2.057); 팔 증상군에서는 상지의 근사용 점수(OR 10.662) ; 손 부위 증상군에 대해서는 손목의 자세/손목 비틀림 지표 (OR 2.068)와 상지의 근사용 점수(OR 2.215); 허리부위 증상군에서는 하지의 근사용 점수(OR 2.601)가 통계적으로 유의한 지표였다.(p<0.05) 이상의 결과에서 작업관련 상지근골격계 자각증상과 RULA 점수사이에는 연관성이 있음이 관찰되었다. 이는 RULA가 직업성 질환을 유발할 수 있는 근골격계 부하에 폭로된 작업자들을 평가하는, 일차적인 작업 위험도 평가도구(Screening tool)로서 쓰일 수 있음을 말해준다. 다만 향후 RULA 사용에 있어서 상지(upper limb)와 허리부위(back)의 평가를 구분하고, 기타 다른 작업관련 요인들에 대한 평가체계를 보완하는 것이 필요하다.

  • 27개 사업장, 1897 근로자를 대상으로 근골격계질환 증상조사표를 받아 근골격계증상과 근로자 개인적 특성과의 상관관계를 분석하였다. 근로자의 근골격계질환 증상 유무는 한국산업안전보건공단의 근골격계부담작업 유해요인조사 지침에 따라 관리대상자 이상을 기준으로 했으며 개인적 특성으로는 작업자의 연령, 업무부담, 가사부담, 직장경력, 여가종류, 성별, 결혼유무로 구분하였다. 조사는 업무부담, 가사부담, 직장경력의 서열변수는 이분형 로지스틱 회귀분석을 통해 상관관계를 조사하였으며 그 외 명목변수는 교차분석과 카이제곱분석으로 해당 결과의 유의성을 확인하였다. 그 결과 작업자의 연령이 낮을수록, 업무부하와 가사부담이 높을수록, 여성일 경우, 여가활동을 가지지 않을 경우 근골격계질환 증상발현율이 높아진다는 것을 확인하였다. 그러나 본 연구의 결과를 다른 연구결과와 비교한 결과 조금씩 결과가 다른 점을 미루어볼 때 본 연구의 자료를 근골격계질환 예방의 개략적인 지표로써 활용할 수는 있지만 정량적 지표로써 활용하가 전 추가적인 연구가 필요할 것으로 사료된다.
