한국은 세계에서 열번째로 많은 1000만명 이상이 인터넷을 이용하고 있다. 학생부터 직장인까지 문서작업과 업무가 컴퓨터로 이루어지면서, 컴퓨터의 사용으로 인한 질병도 확산되고 있다. 모니터에서 발생되는 전자파에 장시간 노출로 인한 각종 전자파 유해가 생기고 여러가지 신경계통에 대한 장해가 증가하고 있다. 이른바 컴퓨터를 통해 정보를 입출력하는 과정에서 생기는 증후군이 VDT(Visual Display Terminal)증후군이다. (중략)

The purpose of this study was to investigate the health conditions of occupation group and hobby group related to visual display terminal (VDT) syndrome. The VDT occupation group was mainly composed of the worker in banks, telephone companies, and general offices. The VDT-related hobby group was composed of high school students, and Internet cafe users. A questionnaire survey was conducted to classify the subjects according to hours of computer usage. The results indicated that the occupation group represented a higher level of subjective symptoms than VDT-related hobby group. In the VDT occupation group, 'Poor body condition', 'Feeling uncomfortable or pain in the neck', 'Feeling uncomfortable or pain in the back', 'Feeling stressed out', and 'Feeling uncomfortable or pain in the shoulder' items indicated a high level of subjective symptoms. In the VDT-related hobby group, 'Feeling uncomfortable or pain in the neck', and 'Feeling uncomfortable or pain in the back' items indicated a high level of subjective symptoms. According to the hours of computer usage, 4-6 hours and 6 hours or more groups represented a higher level of subjective symptoms than 2-4 hours group. These findings suggest that Visual display terminal (VDT) work effects the individual's health conditions.

Purpose: This study aimed to examine the effects of a proprioceptive neuromuscular facilitation (PNF) program on neck pain, cervical range of motion, pressure pain, and the cervical flexion-relaxation ratio in a visual display terminal (VDT) worker. Methods: We recruited a 33-year-old VDT worker diagnosed with chronic VDT syndrome. The subject was treated using a PNF program for 20 minutes a day, three times a week for six weeks. All evaluations were performed every two weeks on the first test day. Results: The PNF program resulted in a significant improvement in the subject's neck pain, cervical range of motion, pressure pain, and the cervical flexion-relaxation ratio after six weeks, in comparison to the subject's condition before treatment. Conclusion: The PNF program can be used effectively to improve neck pain, cervical range of motion, pressure pain, and the cervical flexion-relaxation ratio in visual display terminal (VDT) workers.

종합병원에서는 많은 환자들의 데이터를 효과적으로 관리하기 위해 각종 자료를 전 산화하고 있으며, 그곳에서 근무하는 간호사들은 VDT (Visual Display Terminal) 앞에서 작업시간의 대부분을 보내야만 한다. 간호사들의 요통 유병률이 타 직종에 비해 높은 편이며, 업무와 관련해서 경험한 요통이 간과되는 경향이 있고, 사고보고를 하지 않는 경우가 많아서 실제의 요통 발생률은 보고된 것보다 더 높을 수 있다［1］는 연구결과가 발표된 바 있으며, 이러한 이유에는 여러 원인이 있겠으나, 그 중에서 특히 VDT작업을 하는 간호사들과 작업환경과의 관계를 규명해 보고자 서울 지역의 일부 종합병원 VDT(Visual Display Terminal) 작업 간호사들을 대상으로 실태조사를 하였다. 본 연구의 목적은 VDT 작업 간호사들의 설문지 응답과 직무분석 그리고 작업자세와 작업환경조건 등을 고려하여 VDT증후군에 대한 위험요인을 파악하고, VDT 관련 직업병 예방대책을 마련하고자 하였다. 설문지 분석결과 종합병원 간호사들의 근무환경 및 업무활동과 통증발생 결과간에 관련성이 있음을 알 수 있었다. RULA 프로그램 분석결과인 Level 5가 나왔으며, 이는 3단계 위험수준을 가리키는 것으로 곧 작업환경을 바꾸어야 하는 것으로 나타났다.

These days the use of personal computer has become generalized at factory, office, house, etc and this fact indicates that visual display terminal work became popular in every field of our society. The use of computer improves work efficiency, productivity & qualify but in addition, it also generated the physical and mental diseases or defects so called VDT syndrome to workers. The purpose of this paper is to analyse the computer-work-related anti-physical, anti-psychogenic symptoms & side effects through the data drawn from workers who use computers on their works, and to find out methods of improvement & humanization of computer works. The follows are the results of questions about personal sensibility of VDT syndrome. 1. Female workers are more sensitive to the side effects of computer labor than males. 2. Workers aged twenties feel more severe symptoms of VDT syndrome than thirties or fourties, but there are no level of significance. 3. Middle managements workers are the most sensitive group to VDT syndrome, on the other hand tow managements are less sensitive than operators. 4. The result of questions indicates that a phone conductress show more severe VDT syndrome symptoms than business affairs or an engineer workers, with level of significance. 5. The longer computer work engagement period, the more evident VDT syndrome symptoms appear. For instance, workers who have more than 2 year engagement period complain more severe symptoms, compared workers who have less than 2 year engagement period. 6. Long computer working time per day also increases VDT syndrome severity specially people who have more than 2 hours in working time in a day have much less severe symptoms, compared people whose daily working time exceeds 2 hours. 7. Specific body part which shows VDT syndrome symptoms is shoulder, wrist, neck, finger, eye, waist, arm in the order of severity. 8. Sensibility of VDT syndrome symptoms have effect on degree of vocational satisfaction.

For a video data terminal (VDT) operator, visual strain was caused by continuous VDT operations was found id be recovered by watching the picture of virtual far point with the background of the complementary color when the treatment to recover from visual strain was carried out. When the VDT operator watches the picture of virtual far point with the condition of the complementary color stimuli on the CRT display in 60 or 120 minutes after the start of the VDT operation, the visual strain is recovered and the VDT operator is kept healthy.

최근 급속한 사무자동화와 함께 컴퓨터의 사용이 보편화되어 가고 있다. 또한, PC보급이 급격하게 증가함에 따라 직장에서뿐만 아니라 가정에서도 누구나 쉽게 컴퓨터 작업을 할 수 있게 되었다. 이에 따라 컴퓨터 등 VDT(Visual Display Terminal)를 장시간 들여다보며 작업을 하는 경우가 늘어나게 되고, VDT작업으로 인한 피로, 시각장애, 경견완장애(목, 어깨 및 손목질환), 요통 등과 같은 새로운 재해를 유발할 가능성이 높아지게 되었다.(중략)

In large scale complex system such as a nuclear power plant, it is important to select guidelines and/or checklist to evaluate the system performance, especially human performance for visual information while the number of evaluation items of the guidelines and checklist is voluminous. This paper presents the methodology and experiment for the relative weights or priority selection of evaluation items on the advanced information display of main control room in a nuclear power plant. To summarize this, 1) many human factors guidelines of Visual Display Terminal(VDT) displays are collected, 2) the collected guidelines are integrated and unified based on some rules in a way to avoid confusion or errors about work performances of operator groups, 3) using the unified guidelines, the more important items are defined when the advanced information indexes are applied by using the Analytic Hierarchy Process(AHP). For employing the AHP, the decisions and response of many human factors evaluation specialists in this field are collected to get the priority order of the evaluation items of VDT. The result of this paper will be applied for the evaluation of the usability of next generation of nuclear power plant which is focused on the visual information display on VDT.
