VTS 항해에 있어서 VHF는 선박에서 단순한 통신장비로서만 기능하는 것이 아니라 중요한 항해계기로서의 기능을 수행하고 있다. 항행정보는 물론 항행의도를 교환하여 항행에 관한 의사결정을 조기에 할 수 있도록 도와주는 일들이 모두 VHF 교신을 통해서 이루어진다. 본 논문에서는 VHF 교신 실패에 따른 사고 위험성을 살펴본 뒤 실제 VHF 사용실태와 그 문제점에 관하여 분석하였다. 이를 바탕으로 VHF 커뮤니케이션 개선방안은 물론 이를 실현하기 위한 정책방향을 제시하였다.

Recently, there has been tremendous increase in human-computer/machine interaction system, where the goal is to provide with an appropriate service to the user at the right time with minimal human inputs for human augmented cognition system. To develop an efficient human augmented cognition system based on human computer/machine interaction, it is important to interpret the user's implicit intention, which is vague, in addition to the explicit intention. According to cognitive visual-motor theory, human eye movements and pupillary responses are rich sources of information about human intention and behavior. In this paper, we propose a novel approach for the identification of human implicit visual search intention based on eye movement pattern and pupillary analysis such as pupil size, gradient of pupil size variation, fixation length/count for the area of interest. The proposed model identifies the human's implicit intention into three types such as navigational intent generation, informational intent generation, and informational intent disappearance. Navigational intent refers to the search to find something interesting in an input scene with no specific instructions, while informational intent refers to the search to find a particular target object at a specific location in the input scene. In the present study, based on the human eye movement pattern and pupillary analysis, we used a hierarchical support vector machine which can detect the transitions between the different implicit intents - navigational intent generation to informational intent generation and informational intent disappearance.
