단순 VDT 작업에 의한 인간의 시각정보처리에의 영향을 살펴보기 위하여 특히 서로 다른 model에 대한 정보처리에의 영향을 조사하였다. 피험자는 시각감시 작업과 데이타입력작업을 각각 50분씩 2회 수행하였고 서로 다른 model에 대한 영향을 살펴보기 위해 적업 전, 중 ,후에 걸쳐 MD 및 PD 방법에 의한 과제가 실 시되었다. 실험결과, 단순 VDT 작업이라고 하더라도 작업 수행 내용의 차이에 따라 서로 다른 model에 대한 정보처리에의 영향이 다르게 나타날 수도 있다는 점이 시사되었다.

목적: 발효자색고구마와 블루베리(blueberry)에서 추출한 안토시아닌의 시력보호 및 VDT 증후군 개선효과를 알아보고자 연구하였다. 방법: 실험은 안과질환 및 전신질환이 없고, 굴절이상이 -4.00 D 이상인 19~21세 남 여 20명을 대상으로 실시하였다. 40 mg의 발효자색고구마 및 블루베리 추출 안토시아닌과 대조군으로 위약을 각각 복용, 2시간 후에 근업(VDT)을 2시간 동안 실시하였다. 시력검사는 안토시아닌을 복용하기 전과 2시간 근업 후 각각 타각적 굴절검사 방법으로 측정하였다. 근업 2시간 후 VDT 증후군으로 두통, 안통 및 안정피로, 목, 어깨, 허리 등의 자각증상의 정도를 심함, 보통, 약간, 없음 등으로 구분하여 문진하였다. 결과: 2시간동안 VDT 작업 후 시력보호 효과는 우위안에 대한 굴절 값은 발효 자색고구마 추출 안토시아닌에서는 $0.031{\pm}0.21$ D, 블루베리 추출 안토시아닌에서는 $0.006{\pm}0.32$ D 만큼 근시도가 감소하였고, 위약에서는 $0.144{\pm}0.28$ D(t=2.27, p=0.03) 만큼 유의하게 근시도가 증가하였다. 결론: 발효자색고구마 추출 안토시아닌이 근업 후 굴절이상 값의 증가를 억제하고, 비우위안보다 우위 안에서 시력을 보호하는 것으로 생각된다.

In order to investigate industrial fatigue due to visual display terminal (VDT) work of banking operations the questionnaire survey for subjective symptoms of fatigue was carried out on 470 bank clerks who had been engaged in VDT work for various length of work hours. The questionnaires comprised three groups of 10 items each, representing dullness and sleepiness (level of cerebral activation), difficulty in concentration (level of motivation) and bodily projection of fatigue. The results were as follows : 1. Of the 30 items of questionnaires, the highest percentage was accounted for by 'eye strain' (51.5% ), followed by 'feel stiffness in the neck or the shoulders'(33.4%), 'feel a pain in the low back'(26.8%), 'whole body feels tired'(19.6%) and 'feel headache'(17.9%) in the order of sequence. 2. The average weighted score for the first group of questionnaire items (dullness and sleepiness) was the largest among three groups and was followed by 'the third cup (bodily projection of fatigue) and the second item group (difficulty in concentration) in the order of sequence, suggesting the heavier mental stress of VDT work in banking operations rather than physical burden. 3. In terms of the age and sex of workers, work duration and VDT work percentage, the difference in average weighted score was noted only between sex, the score of female being larger than that of male. 4. The complaint rates of subjective symptoms showed close associations with the subjective optimums of room temperature, ventilation, illumination and noise level. 5. The significant correlation was showed between age, work duration and item of 'whole body feels tired', between VDT work percentage and items of 'eye strain' and 'feel stiffness in the neck or shoulders' and between all items of subjective symptoms.

병원 근로자의 VDT 자각 증상에 대한 선행연구를 보면 대부분이 간호사 관련 직종으로 한정되어 있고, 방사선사에 대한 연구는 수행되지 않았다. 본 연구는 2009년 10월 15일부터 11월 2일까지 대전광역시에 소재하고 있는 종합병원에 VDT 작업을 시행하는 보험심사, 원무, 의무기록, 전산, 행정부서 근무자와 방사선사를 대상으로 구조화된 설문지를 활용하여 분석하였다. VDT 증후군 자각 증상 점수를 종속변수로 한 다중선형회귀 분석 결과 관련요인으로 안관련 증상에 영향을 미치는 요인을 보면 성별, 건강염려, 일상생활 방해이며, 전신증상은 운동, 스트레스, 건강상태 인지 관련, 근골격 증상에서는 임상경력 6-10년, 대인관계, 건강상태 인지 관련 건강염려와 일상생활 방해로 나타났으며, 통계적으로 유의한 차이를 보였다. 피부 증상으로는 연령 20-29세, 결혼여부, 식습관, 건강상태 인지 관련 소화 정도와 일상생활 방해로 나타났으며, 심리 증상으로는 성별, 결혼 여부, 스트레스, 소화 정도, 일상생활 방해로 나타났으며, 통계적으로 유의한 차이를 보였다. 타부서 근로자와 방사선사의 VDT 증후군 자각점수 차이가 크게 나타나지 않았으며, 이는 방사선사의 업무가 VDT 환경으로 변함으로써 VDT 증후군 자각 증상이 일어날 수 있다는 것을 나타내는 것이다. 이는 정기적인 순환근무를 시행함으로써 VDT 환경에 지속적인 노출을 피하는 것이 예방 대책이라 할 수 있다.

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)

Objectives : In order to investigate industrial fatigue due to visual display terminal (VDT) work of post office. Methods : The questionnaire survey for subjective symptoms of fatigue was carried out on 39 post office clerks who had been engaged in VDT work for various length of work hours. The questionnaire comprised three groups of 10 items each, representing dullness and sleepiness, difficulty in concentration and bodily projection of fatigue. Results : The scores of dullness and sleepiness was 16.62, scores of concentration difficulty was 16.35, those of bodily fatigue was 16.23, and total scores was 49.21. Fatigue scores was significantly associated with age and work duration, VDT of work hours, ventilation, illumination, nosie. Conclusions : Data from this study support a statistically significant association between age and scores of dullness, scores of concentration difficulty, between work duration and scores of dullness, scores of bodily fatigue, between VDT of work hours and scores of bodily fatigue.

The objective of this paper is to compare two national guidelines on the VDT work management published by Ministry of Labor(MOL) and Korean Standard(KS), and suggest possible modifications of them. The scope of this paper was limited to the desktop type of VDT jobs, excluding laptop environment. In addition, questionnaires were administered to office workers to collect information on the discomfort levels in meeting the MOL Notification. From ergonomic point of view, the most noticeable differences between two guidelines were found with respect to the heights of chairs and desks. In fact, the ranges specified in each guideline were not the same. In the field surveys, it could be known that work environments should be improved.

Objectives: This study was conducted to evaluate the clinical efficacy of EC102, a composition containing oriental medicine, for relieving VDT syndrome, including eye symptoms and musculo-skeletal symptoms. Methods: The study was conducted by using a double blind randomized controlled trial design. 40 subjects were randomly assigned to the placebo group or the EC102 group. The visual analogous scale (VAS) was used to evaluate various VDT symptoms, including eye pain, eye fatigue, back pain, shoulder pain and so on. Refractory indexes were measured using refractometer, and tear film break-up time (BUT) were measured using fluorescein strip. Blood circulation was measured using photo-plethysmography. Blood pressure and blood biochemistry were also measured. Statistical analysis was conducted by a Mann-Whitney test using SPSS 9.0 software. Results: The EC102 group showed a statistically significant reduction of eye symptoms including eye fatigue, eyelid fatigue, itching, pain, and photophobia when compared with the placebo group (P<0.05). The EC102 group also showed a statistically significant reduction of back pain compared with the placebo group (P<0.05). No side effects on liver function and blood biochemistry were observed. Conclusions: EC102 has significant clinical efficacy for relieving symptoms of VDT syndrome.

Objectives : This study investigated and made comparative studies of the aspect of VBT syndrome by Sasang constitutions, so that Korean medical doctors can manage and treat people who use the internet. Methods : Sasang constitutions were analyzed by using QSCCII. Questionnaires including VDT syndrome, internet usage trends and QSCCII were distributed to freshmen in a high school in Su-won city, Gyeonggi-do, and 600completed questionnaires were analyzed. Results : There were no significant differences among Sasang constitutions in the indexes of optic and mental problems in VDT syndrome. According to the indexes of total health problems. musculoskeletal problems, 'frequent fatigue', 'vacant head', 'dizziness', 'neck pain' and 'lower back pain' in VDT syndrome, Soeumin had the most problems and Taeumin had the least. In the index of 'back pain', in Soyangin had the most problems. Conclusions : There were some different trends of aspects of VDT syndrome among Sarang constitutions, so it is necessary to use the result of this study to make a plan to care for health problems related to using the internet through Korean medicine with additional studies.

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.
