  • The purpose of this study is to suggest efficient methods for estimating population exposed to noises by analyzing differences of population exposed to noises estimated by each method through comparing exposed population estimated by utilizing existing methods and those estimated by using census output areas reflecting the actual population information of each address. For population exposed to noises, the error of exposed population estimated by using the per capita living space turned out to be the biggest, and other estimation methods had no significant difference. For population exposed to excess noises, as a result of analyzing population estimated by each method based on census output areas, the error of the method using a grid noise map turned out to be the biggest. For the method to estimate population exposed to noises by using a noise map, the estimation methods using census output areas and total ground area are considered to be more rational than the grid noise map estimation method or the method to estimate the living space per capita.

  • Assessment of noise exposed population is a method for checking the degree of environmental noise and social influence in order to reduce the risks such as annoyance and disturbance that are generated by environmental noise. Also, this method suggests the preferential noise reduction policy and action plan by accurately assessing the area that noise causes harm to human health. Recently, a noise map, which can predict noise in comprehensive areas, is used for the assessment of noise exposed population, breaking from the methods using existing measures. In particular, countermeasure for the noise can be considered more effectively by using assessment methods of noise exposed population for specific noise levels, areas, and building types which are the main input factors in noise maps. In this study, Assessment methods of noise exposed population by using 2D noise map are compared with those by 3D noise map.

  • Reasonably accurate estimation of the exposed population to the distinct levels of noise is essential to the efficient management of urban environmental noise. This study proposes a method of calculating the number of exposed people to industrial noise by using GIS tool and noise mapping. The exposed population of noise based on estimation of the number of people that lived in each building in urban area is compared with the one based on density of population. This study suggests the six step method that consists of gathering the fundamental data, extracting the property from the digital map, noise mapping based on the three dimensional topography, estimating population that lives in each building, merging the various results with GIS tool, and estimating exposed population to industrial noise through analyzing the noise map with GIS tools

  • Noise maps can be widely used to estimate the effect of various kinds of existing noise on people and to predict the future noise situation resulting from urban development projects, etc. In particular, countermeasure for the noise can be considered more effectively by using assessment methods of noise exposed population for specific noise levels, areas, and building types which are the main input factors in noise maps. In this study, effective assessment method of noise exposed population is presented by manufacturing facade noise maps depending on Korean house types.

  • Objectives: This study was carried out to evaluate the effect of noise exposure and aging on changes in hearing threshold level and the relationship between age and noise. Materials: The author selected 274 male shipyard and assembly line workers as the noise exposed group and 582 males not exposed to noise as the general population group. Data were collected from five years of consecutive annual audiometric tests performed from 2008 to 2012. Results: In the general population and noise exposed groups, there was a reverse phenomenon that hearing threshold level for 2009 was lower than that of 2008, which seemed to be due to the learning effect, but from 2010 hearing threshold level increased. In the noise exposed group, the mean hearing threshold level in the left ear was significantly higher than that for right ear. In the general population group, the older was the age, the higher was the hearing threshold level, especially at 4000 Hz. In the general population and noise exposed groups, frequency, age group and noise exposure independently affected hearing threshold level, and there was no relationship between age and noise exposure. Over all frequencies, the change of hearing threshold level was larger in the noise exposed group than in the general population group. In the noise exposed group below thirty years old, the change at 4000 Hz was remarkable. Conclusions: Age and noise exposure seem to affect hearing threshold level independently and contribute to an additive effect on hearing threshold level.

  • The exposed population of a vulnerable group to high ozone episodes (exceeding 60 ppb/8h) was estimated in Busan metropolitan city from 2000 to 2010. The frequency of high ozone days at monitoring sites and the number of the population aged over 65 were used to calculate the accumulated (total, seasonal, and yearly) number of the exposed older population (EOP) to high ozone episodes during the study period based on administrative areas, by interpolation and zonal mean methods in ArcGIS software. The older population in this city had increased significantly from 2000 to 2010 (representing over 10% of the total population in 2010). The vulnerable areas (e.g. the eastern area of the city) of the EOP to high ozone episodes were different from the areas with frequent high ozone episodes (e.g., the western area) due to the increase of the older population in particular areas. The difference was more significant in spring than in any other season, and in 2010 than in previous years (2000 and 2005).

  • 국내 법적인 건강영향평가로서 환경영향평가 내 위생 공중보건 항목의 평가는 특정 개발 사업에서 배출되는 유해대기오염물질 배출량 및 주변 주요 지점의 노출농도 산정, 이를 활용한 위해성 평가로 진행되고 있다. 하지만 개발 사업부지 주변의 노출 가능한 인구집단 규모를 고려하지 못하는 등 개발 사업부지 주변의 수용체 특성은 해당 위해성 평가에서 제대로 반영되지 못하고 있다. 본 논문의 목적은 개발 사업부지 주변의 노출 가능한 인구수를 산정 반영한 위해성 평가를 위해 잠재노출 인구수의 산정 및 이를 실제 위생 공중보건 항목 작성 시 활용하는 방안을 제안하는 것이다. 개발 사업부지 주변의 인구수 산정 관련한 국내 자료 현황을 파악하고 이를 고려한 잠재노출 인구수 산정 알고리즘을 제안하였다. 나아가 산업단지 개발 시 유해대기오염물질 배출을 가정한 사례 분석을 수행하였다. 잠재노출 인구수를 활용한 위해성 평가는 인구집단 위해도 개념이 적용되어야 함을 제시하였으며, 향후 연구로 평가결과에 대한 건강영향 여부의 판단기준 설정이 요구됨을 제안하였다. 또한 본 논문의 잠재노출 인구수 산정방법을 통해 개발사업의 입지제한 도구로의 활용가능성을 제안하였다. 이번 논문은 위생 공중보건 항목 작성 시 개발 사업부지 주변의 수용체 특성을 반영한 위해성 평가를 수행하는 방안을 제시했다는 것에 의미가 있다.
