To prepare for the ever-increasing demand for air transport, airport operators should be well aware of the timing of the saturation of the facility and increase the capacity of the airport through extension or extension. The capacity of an airport is determined by the smallest value of the facilities that make up the airport, but it is generally customary to determine the capacity of the costly and time-consuming runway as a whole for the airport. For analyzing the capacity of the runway capacity, the study used the most accurate microscopic air traffic simulation, Simmod-PRO, to analyze the saturation time of three runways currently in Incheon International Airport's operation, and calculate the appropriate time for operation of the 4th runway. The study also calculate the relocation of Airport's high-speed exit taxiway for analyzing the increasing of capacity.

In the past 30 years, our aviation demand has been growing continuously. As such, the importance of the demand forecasting field is increasing. In this study, the factors influencing Korea's international air demand were selected, and the international air demand was analyzed, forecasted and reviewed through OLS multiple regression analysis. As a result, passenger demand was affected by GDP per capita, oil price and exchange rate, while cargo demand was affected by GDP per capita and private consumption growth rate. In particular, passenger demand was analyzed to be sensitive to temporary external shocks, and cargo demand was more affected by economic variables than temporary external shocks. Demand forecasting, OLS multiple regression analysis, passenger demand, cargo demand, transient external shocks, economic variables.

Pilot has been fighting to get over fatigue during flight and thought it as a hinderance for safe flight. The fatigue related problem has been the biggest obstacle for aviation safety so far. Even though pilots and airlines try their best to overcome fatigue during flight, they couldn't overcome this problem. So the airliners let the pilot sleep during flight if pilots are too tired with the report. It is controlled rest used and managed by several European airliners. So this study tries to get Korean airline pilots' fatigue information and figure out the cause and reduce it.

As the demand for simulated flight training and interest in new technology training increase, this study analyzed the performance of flight simulator training and actual flight training subjects to confirm efficient flight simulator training curriculum. Summarizing the results of the study, found that flight simulator training had a significant positive effect on the actual flight training performance and in particular had a relatively large effect on the air maneuver, traffic pattern, cross country flight subjects. As a result of analyzing theoretical major classes that affect flight simulator training to verify the correlation, found that principle of air navigation, air traffic service, and helicopter flight theory were affected in order. The significance of this study was to identify the curriculum and ground lesson that should be focused on effectively performing flight simulator training in the helicopter private pilot course.

항로표지는 등광, 형상, 색채, 음향, 전파 등을 수단으로 선박의 위치, 방향 및 장애물의 위치 등을 알려주는 항해보조시설로 해상교통 환경의 중요한 인프라이다. 해상교통환경은 4차산업혁명에 따라 자율운항선박, 스마트항만 등의 기술개발과 더불어 급격하게 변화 중이다. 그러므로 해상교통환경 변화에 능동적으로 대응하고 해상안전을 확보하기 위해서는 기존의 항로표지 고도화 및 정보협력서비스 제공이 필요하다. 본 연구의 목적은 미래 해상교통 관리를 위한 항로표지의 새로운 서비스 실효성을 확보하기 위해 사용자 대상 요구사항을 평가하는 것이다. 본 연구의 결과를 통해 선박운항자 등 사용자 관점에서 미래 항로표지 서비스의 요구사항을 파악할 수 있는 기초자료로 활용할 수 있을 것으로 기대한다.

기존 선박의 안전관리는 선박의 선원들에 의해 많은 부분이 결정되었다. 하지만 최근 위성통신 기술의 발전에 따라 선박에 있는 다양한 센서 데이터를 육상으로 전송할 수 있게 되어, 데이터 기반의 선박 안전관리에 대한 수요가 높아지고 있다. 본 연구에서는 선박에서 데이터 수집을 통해 어떻게 안전관리를 할 수 있는지 알아보겠다.

Since 2003, policies and practices related to the reduction of CO₂ gas emission from ships has been discussing by the International Maritime Organization. The representative emission index and indicator are the EEDI (Energy Efficiency Design Index) for the new ships and EEOI (Energy Efficiency Operational Indicator) during the voyage. For the CO₂ emission monitoring system, the SEEMP (Ship Energy Efficiency Management Plan) is also on the table. This global preparations to reduce theCO₂ emission is not except for the surface transportation. This research report elucidates the recent stream on the IMO CO₂ emission from ship and detail explanation on the EEDI and EEOI.

Gyeongin Ara Waterway will be open on Oct., 2011, Which is the first inland artificial waterway constructed in Korea. There have been arguments about the environmental issues and economic effectiveness, however, it's now time to focus on the safety of navigation at the waterway to protect human life, property and environment. Therefore this paper aims at examining the establishment of the rule of safe navigation and management for the safe and effective management of the waterway and tries to draft the rules based on these examinations. The draft rule consists of 7 chapters, which are general rules, general rules on navigation, specific rules on navigation, general restrictions, emergency response, restrictions on navigation and penalties in consideration of the characteristic of Gyeongin Ara Waterway and regulations on navigation in major canals in the world.

The goal of a simulator is to provide for the testing of new technologies and to facilitate the eventual transfer of these technologies to the applications. In the Development Step, Simulation can provide a cost effective alternative to expensive and hazardous field testing. In this paper, a 3D simulator is developed to test UUV navigation system bated on RVC model. The simulation system consists of a environment manager, objects and a 3D viewer. Objects are modeling all physical elements such as map, obstacle and UUV which reside in a underwater environment. Those objects are created and initialized by environment manager. The environment manager plays the role of intermediator which allows created objects to interact with each other, and transmits information on the objects to 3D viewer. The 3D viewer analyzes the received information and visualizes 3D graphic by using OpenGL primitives.
