After analyzing each procedure from standard instrument procedures used at Incheon International Airport, which is believed to have caused noise problems in and around Ganghwa island, we came to a conclusion that some Standard Instrument Departure Procedures and Standard Instrument Approach Procedures need to be revised, and therefore we made some propositions with regard to noise abatement procedures(CDA, RNAV approach etc.). Additionally, we evaluated viability of the proposed flight procedures by conducting a number of demonstrations with use of flight simulation.

The INM simulation program is used to estimate the condition of the exposed area to the noise near a military airport in Korea. $WECPNL_k$, the evaluation unit of korean airport noise, is different from the ICAO $WECPNL_I$ that is used in the simulation program. Therefore, it is inappropriate to compare these units each other directly. This study presents method of comparison between them by using $LA_{MAX}$. The aircraft events are classified into three classes, as departure, overfly and approach. In result, the measurement and simulation seemed to be similar at departure and approach pattern. However, overfly pattern had higher errors between measurement and simulation. Finally, it is necessary to examine the method to determine flight events and duration for the $WECPNL_k$ application.

This study has measured and evaluated the sound insulation of building elements of the hotel near airport. That measurement was made in both the actual site and laboratory. The differences of sound insulation performance in between granite and double glass were measured. Moreover, the difference of sound insulation was analyzed. For the measurement, this study has tried several methodologies, and analyzed the differences respectively. The results from this analysis were applied to produce a design guides for sound insulation to prevent external noise and to make more silent indoor space which satisfied the standard rate of noise.

When measuring the value of environmental attributes of housing, the conventional Hedonic Pricing Method assumes market equilibrium. Thus each attribute is believed to be implicitly valued based on the market price. The revealed preference is the basic logic in this approach. However, if the participants in the housing market are not perfectly informed or feel vagueness regarding the attributes of the housing, the conventional Hedonic Pricing Approach could not provide relevant value of the attribute in question. A Fuzzy Regression Method is suggested to handle with the lack of information or preference uncertainty problem m the Hedonic Pricing Approach. In this paper, our main concern IS given to the fuzziness effect on the airport noise in the metropolitan areas of South Korea.

To minimize the occurrence of aviation accidents in the post-COVID, continuous flight training is crucial. However, the current infrastructure of domestic airports and airfields is insufficient to prepare for and respond to accidents, and there is a need for sufficient facility capacity. Therefore, this study examines the construction of a regional airport to minimize aviation accidents and selects factors necessary for determining the site location. Among the 11 selected factors, six were considered the most important site selection factors, including noise issues, weather conditions, obstacle limitations, environmental issues, airspace conditions, and facility usability. Applying these factors, an analysis was conducted on the Songpo area of Sacheon City, Gyeongsangnam-do. Based on a comprehensive review, it can be concluded that the Songpo area is a suitable choice for a regional airport due to its excellent transportation environment, consideration of noise and environmental issues with the residential population, and other factors. Furthermore, the development of the aviation industry is expected to bring about an increase in tourism and economic benefits, and it is anticipated to make a significant contribution to the domestic aviation industry along with the construction of the currently under-construction Ulleung Airport.

Community noise has been serious social issues in Korea. The community noise concerns on traffic, construction, factory, and apartment complex noise. In traffic noise, road, railway, airport sectors are included. This paper summerizes the final report prepared for MOE in 2005 by authors. The new policy will be enforced beginning in 2006 with 5 year schedule. Details on the policy will be demonstrated at the presentation.

This study describes the relationships between aircraft noise and stress and subjective noisy perception by comparing with two areas where the airport is adjacent or not. One area is Yipam-dong and Hak-dong expected to have louder aircraft noise because Kangnung Airport is near the area, and the other area is Songjung-dong as a control. For this study, we used telephone-survey which was targeted to two hundreds people of each area through the random sampling method. The design of the study is cross sectional study and the unit of analysis is a person. As the result of the multiple regression and logistic analysis, under the control of the other control variables, the both stress levels and subjective noisy perception of Yipam-dong and Hak-dong people significantly higher than that of Songjung-dong people and the people graduated middle school had significantly higher both stress levels and subjective noisy perception than the people graduated high school. In the future more studies have to be made that include concrete medical and psychiatric health problems.

This study was carried out to evaluate health effects of aircraft noise using THI(Todai Health Index). The questionnaire survey was conducted around the Gimpo International Airport in Seoul, Korea from 8 August to 9 September. Study subjects, 614 residents, were divided into three groups following to the aircraft noise level: under 75WECPNL(area(1)), $75{\sim}80$WECPNL(area(2)) and $80{\sim}85$WECPNL(area (3)). Twelve scale scores are converted to dichotomous variables based on scale scores of 90 percentile value or 10 percentile value in the control group. Logistic regression analysis taking twelve scores converted as the dependent variables and WECPNL(area), age, gender as the independent variables is conducted. Significant dose-response relationships are found in the scale of MOUT, DEPR, NERV, LIFE, where p denotes significance probability of trend test. Factor analysis was carried out and 2 factors are extracted which may be called "somatic factor" and "mental factor". The dose-response relationship with these factors and noise exposure is not clear. But strangely the odds ratio of mental factor in area 2 is the highest and the annoyance of this area is also higher than other areas.

Because many people suffer physical and mental damage from the noise of the traffic facilities including road, rail, airport, the advanced countries have conducted the researches of predicting and solving the impact of the human health exposed to traffic noise. Therefore, this study suggests the fundamental plans which can assess the health impact of traffic noise on the basis of the prediction results about the health impact of traffic noise.

Exterior noise generated by the aircraft induces a serious noise pollution near the airport. For the prediction of an exterior noise radiation of aircraft an empirical formula is employed to model the acoustic sources. It is shown that the fan/compressor noise is the most dominant part of the acoustic sources in all cases.
