  • 현대사회의 산업 현장에서 기계가 사람들을 대체하면서 작업의 효율을 높이고 있다. 많은 산업 분야에서 사람들을 기계로 대체하고 있는데, 재해 및 사고 현장이나 위험 지역 조사 등에 대한 탐사 활동은 대부분 인력이 차지하고 있으며, 탐사 활동에 참여하는 많은 인력들은 2차, 3차 사고에 쉽게 노출되어 있으며, 그로 인한 인력소모가 심하다. 따라서 우리는 인력 투입 전 사고 및 재난 현장이나 위험 지역에 인력을 투입하기 전 피해를 최소화 하면서 탐사 인력에 대한 안전이 보장된 근무 환경을 개선 시키기 위해서 무인 탐사차량을 생각하게 되었다. 무인 탐사 차량에는 아두이노와 라즈베리파이를 메인으로 삼았고, 현장의 온도와 습도, 화재여부, 가스여부를 측정하기 위한 센서들은 아두이노에 연결하고, 카메라와 라이다센서의 경우 라즈베리파이에 연결을 하였다. 그리고 모든 데이터값은 블루투스와 와이파이 모듈을 통해서 수신받을 수 있게 프로그램을 구성하였다.

  • Air transportation demand is consistently increasing in Korea due to economic growth and low cost carriers. For this reason, airport expansion plans are being discussed in Korea. Therefore, it is essential to forecast reliable air transportation demand with adequate methods. However, most of the air transportation demand models in Korea has been developed by simple regression analysis with several dummy variables. Simple regression analysis without considering stationarity of time-series data can bring spurious outputs when a direct causal relationship between explanatory variables and dependent variable does not exist. In this paper, econometric model were developed for air transportation demand based on stationarity in time-series data. Unit root test and co-integration test are used for testing hypothesis of stationarity.

  • As part of the ongoing global process of airlines forming strategic alliances, Korean Air has become a member of the SkyTeam Alliance, while Asiana has joined the Star Alliance. However, as something akin to the Anti-Trust Immunity(ATI) initiative has not been ratified domestically, these two airlines have seen their roles within these strategic alliances significantly reduced. In keeping with its domestic airline liberalization policy the U.S. government has instituted a mechanism through which foreign airlines that join such strategic alliances with their American counterparts can be exempt from the U.S. antimonopoly law. As a result, U.S. airlines have been able to forge wide ranging cooperative relations with foreign airlines, and thus increased their competitiveness within the air transport industry. This study analyzes the applicability of this Anti-Trust Immunity initiative to the domestic environment.

  • According to the State Safety Program (SSP) of the International Civil Aviation Organization (ICAO), it is essential to establish and manage Safety Performance Indicators (SPIs) which are used for monitoring the safety performance to achieve the national aviation safety goal. There have been enormous efforts to develop the framework of SPIs by considering the current status for each country. In case of Republic of Korea, however, there has been limited research and policy projects related to the framework for SPIs. Furthermore, Korea has used identical SPIs since the SSP was legislated in 2008. With this background, this research is, as part of strategy for the state level of SPI development, the study cases of advanced aviation countries for SPI development plans, such as the European Aviation Safety Agency (EASA) of the EU, the Civil Aviation Authority (CAA) of the UK, the Finish Transport Safety Agency (FTSA) of the Finland and the Federal Aviation Administration (FAA) of the U.S. The comparison between the foreign and domestic policies for SPI development strategies are provided in the conclusion of this study. The results and analyses of the case studies performed in this research will be helpful to provide some valuable development strategies for further SPI research in Korea.

  • This study was conducted in search of the acceptance level of air traffic services from domestic airlines pilot's perspective in comparison with male controllers and female controllers. Pilots responded to the questionnaire that female ATC controllers are of significance to male controllers in terms of pronunciation, accuracy of English grammar, attitude and kindness. Besides, The ICAO aviation English proficiency level four test revealed that female controllers were found superior to male controllers in terms of rating scales of holistic descriptors.
