인간이 도구를 사용한 이래 진동과 충격의 인체 피폭은 점진적으로 증가되었으며, 산업 혁명의 부산물인 동력기관을 이용하는 육-해-공 운송수단의 20세기 발전은 인체진동 피폭의 급격한 증대를 수반하였다. 자동차를 포함한 운송수단은 21세기 우리생활의 필수품으로 확고한 자리를 잡을 것이 확실시된다. 우리 주변의 수많은 진동 발생원들과 이에 직간접적으로 노출되어있는 현대인의 생활은 진동에 대한 새로운 이해와 접근방법의 개척을 요구하여 새로운 공학분야를 잉태하였다.(중략)

This paper introduces the brief guidelines on general aspects of tests and experiments with human subjects. Detailed methods for measuring whole-body vibration are reviewed for those tests and experiments and compared each other. Such comparison is found to be very useful in choosing adequate methods for human related tests and experiments. Of course, it is also expected to be very meaningful to our automotive research and industrial fields that are critical to the ride quality of their products with uncomfortable acoustic noise and vibration.

This Paper addresses what amount of whole-body vibration is exposed to Korean pilots of UH60 helicopters during their mission flight. To measure the expose4 whole-body vibration, the 12-axis whole-body vibration measurement system was used. It enables the direct measurement of whole-body vibration exposed from the body contact area consisting of the feet, hip and back. The measured 12-axis vibration signals were used to evaluate the vibration comfort level experienced by the pilots of UH60 helicopters. The evaluated vibration comfort level is found to be closeto 0.74-0.79m/s, which is equivalent to the semantic scale of 'fairly uncomfortable'. To assess the health effects of whole-body vibration exposed to Korean pilots of UH60 helicopters during their mission flight, the rms-based and VDV(vibration dose value)-based evaluation schemes, recommended by ISO 2631-1:1977, were exploited in this work. The evaluated results indicate that Korean pilots cannot avoid the fatigue-decreased proficiency limit after two-hour continuous flight. The whole-body vibration level exposed from the UH60 helicopters during continuous 10-hours mission flight is found to reach to the vibration exposure limit.

This paper reviews recent international standards related to human-related vibration and compares them to KS standards. This comparison and analysis reveals that the current direction and activity in ISO is in progress and presents logical ways of updating Korean standards in the future. Finally, the current activity of upgrading Korean standards in the Korean TC 108/SC 4 is introduced.

This paper introduces experimental results related to the vibration ride conditions that a korean male subject experienced in the nationwide railway trains and the express bus. Two types of railway train's Saemaulho and Mugunghwaho. and the express bus were chosen to measure how much the whole-body vibrations on the contact area of the back , hip and feet are exposed to the subject. Measured vibration signals were analysed to assess the rife conditions quantitatively and qualitatively. Analysed results are illustrated to unveil how much typical public transportation system in Korea expose whole-body vibration to passengers. Futhermore, the performance evaluation of their seats were carried out to examine their effectiveness in reducing vibration exposure to passengers.

현재 ISO 에서는 공구제조업체에서 해당 공구의 수전달 진동을 측정하여 제시하도록 하는 규격을 제정 중에 있으며, 이를 위해서는 공구에서 발생하는 진동과 영향을 평가하는 기술이 확보되어야 하며, 이 과정에서 측정 불확도 수준을 결정하는 것이 매우 중요하다고 하겠다. 본 연구에서는 동력 공구 작업시 작업자의 손으로 전달되는 진동을 측정하고 그 영향을 평가함에 있어서 발생할 수 있는 불확도를 분석하였다. 먼저, ISO 5349 규격을 적용함에 있어서 존재하는 불확도 인자들을 분류하고, 각 인자들이 어느 정도 수준의 불확도를 발생시키는지 시험을 통해서 확인하고 분석하였다.

The recent national contract (Ecotechnopia 21) supported by the ministry of environment puts much significance on new issues for the assessment of human effects arising from vibration and noise exposed to human. This paper focuses only on hand-arm vibration since it has been a major problem in protecting vibration exposure to human. To set up a systematic way of assessing adverse effects of hand-arm vibration, surveys were made on recent international standards and researches related to hand-arm vibration. The measurement and evaluation methods of hand-arm transmitted vibration, the relationship between vibration exposure and effects on health, and the assessment methods of nerve dysfunctions are addressed in this paper. Those methods are linked into a logical way of assessing effects of hand-arm vibration on human. Finally, the current activities and achievements in this work are briefly summarised.
