The shipboard working environment of navy vessel is very inferior to the ground working environment. For this reason, the crew of a navy vessel suffer from an occupational disease such as lumbar pain, hearing loss, etc. Although standard for navy vessel's environmental vibration is applied, the criterion of the environmental vibration is too high. So it doesn't help to improve habitability of crew. In this study, for improving its habitability of crew, the current vibration level of navy vessel was examined and the standard of navy vessel's environmental vibration was investigated.

Urban subways usually make environmental problems because subway vibrations are transmitted to building structures. However, when the buildings are designed, vibrations due to subway are not usually considered in advance. This results in many environmental vibration problems after buildings are constructed. This study was carried out to set up and evaluate a pre-assessment technique for the environmental impact of urban subway vibration on newly planned buildings near a subway line. for this purpose, semi-emperical method was set up and vibration measurements were made on site in accordance with construction schedule. Computer simulation was also performed using ANSYS software to predict the building vibration and compared with the measured results for evaluation of the pre-assessment technique.

In China, environmental noise policies are composed of correlated laws adopted by the Standing Committee of the National People's Congress and promulgated by the President of the country, regulations promulgated by the State Council and/or local government, standards issued by the Standardization Administration Committee (SAC) under the State Council. The laws mainly include the 'Environmental Protection Law' and the 'Law on Prevention and Control of Pollution From Environmental Noise' Regulations are often applied to a special noise pollution phenomenon of wide influence. They are generally only effective in a given area and/or a specific period. Tens of correlated standards specify the noise level limits of different functional zones of land use and of different equipment, machines, devices, appliances etc., and the measurement methods. In this presentation, a brief introduction to these policies and their operations is given and discussed. The conclusion is that the policies supply an effective legislative basis for environmental noise prevention and control in China, but still a lot of work should be conducted and completed to strive for a quiet society.

Recently, many indoor driving ranges are being built near residential areas because golf is one of the popular sports. Consequently, environmental noise occurs in the residential areas. This study is to predict the noise near the indoor golf driving range by the computer simulation(commercial software Raynoise 3.0) for various cases of noise control methods.

This paper presents an information system of noise and vibration caused by people as a major source of the environmental problem in residential areas with which people are dissatisfied. Therefore, it is important to monitor the influence of noise and vibration in residential areas. Generally, Geographical Information Systems (GIS) play an important role in noise and vibration mapping. The purpose of this paper is to investigate noise and vibration effects in an urban area and develop a new information network in GIS. Noise and vibration measurements were carried out at a road randomly chosen near INJE University. The obtained values are graphically represented with GIS. Therefore, it is possible to predict noise and vibration in GIS when establishing effective urban plans.

The energy efficiency and environment-friendly aspect of the railway system would be superior to other on-land transportation systems. In a preliminary feasibility study stage, the energy efficiency and problems related with environment are usually not considered. The railway noise and vibration which could be reasons of environmental problems are focused and studied in this paper. The investment for railway systems could be encouraged by the considering of main environmental elements evaluated with the modified noise and vibration standard for environment-friendly railway construction.

Although the environmental conflicts regarding noise and vibration are continually increasing during construction, noise and vibration occurring in construction are only managed in construction phase. Noise and Vibration occurring in construction are considered to be insufficient, so we find that noise and vibration management in design phase has to be operated for reducing. The objective of this paper is to present noise and vibration management lists to consider in design phase for enhancing efficiency in noise and vibration management and to develop the appraisal sheets for designers to evaluate and the manuals to easily use management lists. To achieve this, we identify the noise and vibration management lists to consider in design phase through analyzing the previous literatures and confirm the 9 lists through conducting a research with experts in environmental area for verifying the propriety of lists. Also, this study applies to AHP technique to identify the priority and the weight evaluation among the lists. Through this study, we identify the most efficient lists, including from the low noise and low vibration methods, the noise and vibration reduction by blasting works, the installment and the arrangement of noise and vibration control equipments, for noise and vibration management in design phase. The achievement of this study will help to prevent the environmental disputes and conflicts in advance and will consider utilizing for the successful construction project.

As the number of the apartments is increasing, many environmental problems are also occurred. There are lots of studies on that problems. Especially, a lot of studies about environmental noises are going along continuously. And they found out advanced results. In this study, we investigated the residents' subjective responses about environmental noises by survey, and verified the trend of the environmental noise conditions in apartment house. The results of this study will be useful to provide guideline to make policy of environmental noise and criteria.
