Flight education is an essential element in ensuring the development and safety of the aviation industry. Korea's aviation industry has grown rapidly, and the need for professional flight training is increasing accordingly. The purpose of this paper is to analyze the current status of Korea's flight education environment and seek ways to improve it. In addition, we examined whether the operation method and educational environment of Korea's professional pilot training institutes were structured appropriately for student education, and conducted a survey on the flight education infrastructure targeting trainees, instructors, and aviation workers receiving training at Korea's pilot training institutes. Through the survey, we investigated the necessity and urgency of improving the infrastructure for domestic flight education and drew meaningful conclusions.

This study simulates and compares the evacuation time and characteristics according to the living patterns on board a training ship which was launched in Dec. 2005, on the viewpoint of the various activities being possible on board a cruise ship. Based on interviews with personnels on board, 3 living patterns are set as representative living conditions; Pattern A(all personnels are positioned at their cabins), Pattern B(all personnels are positioned at lecture rooms, offices or else), Pattern C(all personnels are positioned at restaurant or cafeteria). The simulation results show that Pattern B is comparatively ideal because the evacuation time is short and there is less delay of personnels' movement on each deck. On the contrary, Pattern C is evaluated as the worst because the average evacuation time took more than 360 seconds and the bottle-neck happened at Upper deck. As a result, this study proposes the needs of various countermeasures against the fire and/or disaster, considering the various living patterns on cruiser(s) and/or passenger ship(s).

Various studies on the method of ship collision risk assessment for alarm have been reported constantly, and the result of the studies is applied to navigation devices. However, it is known that navigators ignore or turn off frequent alarms from the devices of predicting collision risk, because they may avoid collisions in the most of situations. In oder to make the prediction of ship collision risk more useful, it is necessary to consider the customary actions of ship collision avoidance. This paper proposes a system of analyzing collision avoidance measures of ships according to the types of encounter and managing the avoidance history of each ship. The core module of the system is designed as a neuro-fuzzy based inference system, and the test of the module validates the proposed system.

The runway occupancy time of landing aircraft is an important factor in determining runway capacity. The purpose of this study is to suggest improvement measures for runway occupancy time to improve the operation of existing airports. In order to derive improvement measures, a comparative analysis was conducted on the effectiveness of improvement using aircraft operation status data for specific days at the case airport. The FAA REDIM model was used to analyze the improvement plan, and the improvement application function of the model was used to confirm the effect of improving runway capacity by adding a rapid escape taxiway to an airport without a rapid escape taxiway. This study's approach can be applied to the derivation of runway improvement measures and preliminary prediction of effectiveness, and it presents cases that can be applied to future airport construction projects or airport improvement projects.

The purpose of this study is to analyze the effect of self-esteem on the safety culture and safety behavior of airline pilots and to confirm whether job satisfaction has a mediating effect in these relationships. It was examined whether self-esteem directly affects safety culture and safety behavior, and indirectly through job satisfaction. As a result of the study, self-esteem did not have a direct significant effect on safety culture, but indirectly had a positive effect through job satisfaction. In addition, self-esteem had a direct significant positive effect on safety behavior, and job satisfaction partially mediated this relationship. This suggests that pilots with higher self-esteem practice safety behavior more actively, and job satisfaction can promote such behavior. These results show the importance of organizational support such as programs and support for enhancing pilots' self-esteem, fair compensation for improving job satisfaction, improving working environment, and providing career development opportunities in airlines, and are intended to be used as basic data for this.

우리나라 첫 연안VTS인 진도 연안VTS의 운영 성과를 분석하고, 운영 사례를 조사하여 연안VTS기능에 관하여 실증적으로 분석하였다. 연안VTS는 관제구역이 넓어 해상교통 특색이 장소마다 상이하며, 집중 관제를 필요로 하는 곳이 많았고, 통항선박 중어선과 같은 비관제 대상 선박이 다수를 차지하여 이들의 관제가 중요한 것으로 조사되었다. 그리고 선박 운항자의 집중도가 항내보다는 떨어지므로 인적과실에 의한 사고 개연성이 높은 것으로 분석되었다. 연안VTS는 항만VTS와 같이 정보제공, 항행지원, 교통관리의 역할을 주로 하고 있지만, 수색구조 지원, 해상 보안, 해상치안 업무, 해양오염 대응, 비관제 대상 선박 업무 및 수상레저 안전관리 등의 기능을 강화되는 것으로 나타났다.

우리나라는 항만운영의 효율성 및 선박 안전운항을 위하여 1993년 포항을 시작으로 전국 18개의 VTS 시스템을 설치 운영하고 있으나, 최근 선박 교통량의 증가와 더불어 해양사고의 증가 원인으로 인적요인에 대해 연구 필요성이 대두되고 있다. 특히 해상교통관제 업무는 고도의 주의력과 예측능력을 요구하므로 이를 저해하는 인적요인을 분석 및 관리할 필요성이 있다. 따라서 본 연구에서는 VTS 관제실의 근무환경에 대해 설문조사를 통한 요구사항 분석과 함께 현장조사를 시행하여 분석함으로서 VTS 관제장비 및 관제석의 최적 배치방안을 제시하여 최상의 해상교통관리 체제 구축에 대하여 고찰해 보았다.

국내에서는 대한항공이 2006년 8월 17일에, 북극 항공로를 처음으로 운항하기 시작한지 벌써 3년이 넘어서고 있는 현실에서 국내 항공기의 승무원 및 승객 보호를 위한 우주방사선 안전 기준 연구가 시급한 것이 현실이다. 특히 우주방사선 관리의 필요성을 명시한 생활주변방사선 안전관리법안이 현재 국회 심의중이고, 이에 따른 우주방사선 관련 정책 개발 연구 과제를 한국천문연구원 태양우주환경연구그룹에서 진행 중이다. 이 과제의 현재까지의 진행 상황 및 안전조치 방안들에 대한 나름의 제안에 관해서 이번 발표에서 다루어 질 것이다.
