In this article, we verify to influence in the management performance by the safety management system that is recommended by the ICAO for the safety management on the airside area in the airport. Also, We present a comprehensive mediator effect that the employees perceive safety culture and safety behavior. We design how participants were selected as study the employees from 4 airports on the airside areas of the Incheon International Airport, Gimpo International Airport, Jeju International Airport and Gimhae International Airport in the Korea using the simple random sampling method. The instrument for data collection was a questionnaire, and it was developed. Data analysis was to conduct structural equation modeling. Test of the hypotheses were verified to Maximum Likelihood Estimator. As a result of the analysis, safety behavior and risk management of the safety management system found out that affect management performance. Also, the employees of a high awareness about safety policy could be seen that is a high impact on management performance through a safety culture and a safety behavior. Safety behavior has significant mediator effect within the relationship between the safety management system and management performance. So, We provide guidance of the safety policies for the safety management on the airside area in the airport.

본 논문은 기록된 항적 데이터를 이용하여 혼잡한 공항의 비행 절차별 위험도를 분석하는 방법론을 제시하고, ADS-B (automatic dependent surveillance-broadcast) 데이터를 기반으로 재생성된 100일 치의 항적 데이터를 사용하여 인천국제공항과 김포국제공항의 비행 절차별 위험도를 분석한 결과를 보여준다. 위험도 분석은 DWC (detect and void well clear) 를 이용하였으며, 이를 통해 비행 절차별로 가장 높은 위험도가 나타나는 구간과 위험 발생이 잦은 구간을 평가하였다. 그 결과, 인천국제공항의 표준계기출발절차 중 RNAV BOPTA 1L의 SI712 - RANOS Fix 구간에서 가장 높은 위험도가 나타났으며, 표준계기도착절차 중에서는 RNAV GUKDO 1N에서는 SI947-DANAN Fix 구간에서 가장 높은 위험도가 나타났다. 또한 김포국제공항의 표준계기출발절차 중에서는 RNAV BULTI 1X의 SS726 - SS727 Fix, 표준계기도착절차 중에서는 RNAV OLMEN 1D의 KAKSO - KALMA Fix 구간에서 가장 높은 위험도가 나타났다.

The final purpose of this study is to develop noise abatement procedures for minimizing the environmental impacts caused by aircraft noise in the vicinity of Gimpo Int'l Airport, and to establish appropriate noise limits and monitoring system. The results of study was suggests for more detail the crucial factors which one is reference noise level, $L_{MAX}=88dB(A)$ at 6.5km after take-off, and second one is to installation the additional three(3) noise monitoring system on both side of runway.

Poor visibility is very important information in aviation meteorology factor, because secure safety, trust and economical efficiency increase for aircraft movements. The Incheon International Airport 4 years recent times was to period aircraft movements delay and cancellation due to meteorology is 52% and 30%. And then fog is 63% and 43% in meteorology factor. Therefore, the analysis against the economic loss size of an airline due to the fog is necessary. This study is indirectly estimated economic disaster scale of flight return and cancellation due to the fog in the Incheon International Airport from 5 to 6 March 2006. This is based on an aviation operational statistics data and meteorology observation data. Result of estimated, total 14 flights return to Gimpo, Jeju and Gimhae in this period are about 208,205,700 won. And estimated total 10 flights cancellation are about 718,657,000 won.

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.

The effects of weather on aircraft operations are predominant. In particular, severe weather, such as fog, strong winds, rainfall and snow, can cause delays, diversion or cancellation of operations. Of these, fog is considered the main reason for restricting aircraft operations. Meanwhile, Precision instrument approach using instrument landing system(ILS) has allowed aircraft to land safely even in situations where visibility is limited. However, the precision instrument approach require not only the performance of the aircraft but also the enhancement of the runway. In November 2018, Gimpo international Airport raised the category of the runway 14R from CAT-IIIa to CAT-IIIb to improve aviation safety and operational efficiency. Based on this, the research presented a methodology for estimating benefits according to the category upgrade of the precision approach runway, and estimated the benefits to Gimpo International Airport based on the methodology presented.

Recently, Intense competition is expected to bring about continuous change with the rapid global aviation industry. In particular, domestic passenger demand has been steadily increasing over the past five years, with domestic and international shipments growing at a CAGR of 8.4% and 10.0%, respectively. In addition to the economic value of the airport, social interest due to greenhouse gas emissions is also rising. In this study, we analyzed the efficiency of airport operation by using DEA model(Directional Technology Distance Function) considering undesirable output for 14 airports in Korea. As a result of analysis, all airports except Gimhae, Yangyang, Cheongju and Yeosu were analyzed as efficient airports. However, only Gimpo, Gimhae, Jeju, Muan, Daegu and Gwangju were analyzed as efficient airports considering the undesirable output.

This study evaluates the impact of aircraft noise on people's health using the Todai health index(THI). A questionnaire survey was conducted in the vicinity of Gimpo International Airport in Seoul, South Korea, from August 8th to September 9th, 2005. The survey area was divided into three groups based on different aircraft noise levels : area (1) for $80{\sim}85$ WECPNL, area (2) for $75{\sim}80$ WECPNL and area (3) for less than 75 WECPNL. In each area, approximately 200 respondents were sampled. Twelve scale scores of THI 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. Factor analysis was carried out and 2 factors are extracted. Those two factors might be called the "somatic factor" and the "mental factor". The dose-response relationship between two factors and noise seems to be unclear. Unexpectedly the odds ratio of the menatl factor in area (2), where the noise exposure level is lower than that of the area (1), is the highest and the annoyance in this area is also higher than area (1).
