With the rapid development of battleships, weapons manufacturing and electronic technology, naval combat will present some new characteristics. Additionally, naval combat is facing unprecedented challenges. In this paper, we discuss the topic of medical rescue at sea: what challenges we face and what we could do. The contents discussed in this paper contain battlefield self-aid buddy care, clinical skills, organized health services, medical training and future medical research programs. We also discuss the characteristics of modern naval combat, medical rescue challenges, medical treatment highlights and future developments of medical rescue at sea.展开更多

Automatically extracting useful se- mantic information and generating highlight summary from sports video to facilitate users’ accessing requirements is an important problem, especially in the forthcoming broadband mobile communication and the need for users to access their multimedia in- formation of interest from anywhere at anytime with their most convenient digital equipments. In this paper, a system to generate highlight summaries oriented for mobile applications is introduced, which includes highlight extraction and video adaptation. In this system, several highlight extraction techniques are provided for field sports video and racket sports video by using multi-modal information. To enhance users’ viewing experience and save bandwidth, 3D animation from highlight segment is also generated. As an important procedure to make video analysis results universally applicable, video transcoding techniques are applied to adapt the video for mobile communication environment and user preference. Experimental results are encouraging and show the advantage and feasibility of the system for multimedia content personalization, enhancement and adaptation to meet different user preference and network/device requirements.展开更多

Incorporating the forest landscape into farming systems has promoted the development of integrated production systems such as agroforestry. However, many aspects of the relationship between farming and the forest landscape have changed since the modernization of agriculture introduced by the Green Revolution. The objectives of this review are：（1） to contribute to the understanding of the changes in cultivation strategies and in the dynamics of agricultural systems,particularly in the context of farming in Santa Catarina State, Brazil;（2） to contribute to the understanding of agroforestry systems as a strategy to reintroduce the element of forestry into agricultural production systems; and（3） to compile a list of forest plant species that could be used in agroforestry. The approach adopted in this manuscript seeks to highlight the potential of agroforestry systems to conserve natural resources and thereby to support agricultural development by connecting environmental conservation with income for farmers.展开更多
