Towards a Cyber-Physical Range for the Integrated Navigation System (INS)

The e-navigation concept was introduced by the IMO to enhance berth-to-berth navigation towards enhancing environmental protection, and safety and security at sea by leveraging technological advancements. Even though a number of e-navigation testbeds including some recognized by the IALA exist, they pertain to parts only of the Integrated Navigation System (INS) concept. Moreover, existing e-navigation and bridge testbeds do not have a cybersecurity testing functionality, therefore they cannot be used for assessing the cybersecurity posture of the INS. With cybersecurity concerns on the rise in the maritime domain, it is important to provide such capability. In this paper we review existing bridge testbeds, IMO regulations, and international standards, to first define a reference architecture for the INS and then to develop design specifications for an INS Cyber-Physical Range, i.e., an INS testbed with cybersecurity testing functionality.

How Does Tourist Experience Affect Environmentally Responsible Behavior?

Mountain tourism is an important part of China’s tourism market. Tourist behavior is essential to environmental protection and the sustainability of destinations. This paper takes environmentally responsible behavior (ERB) as an important tourist behavior. It breaks down the dimensions of the traditional tourism experience, such as hedonism, participation, novelty; or hedonism, involvement, novelty, local culture; and analyzes the influence of entertainment, education, aesthetics, and escape on place attachment from the nature of the tourism experience. It then incorporates nature bonding into the system of place attachment and analyzes the relationship with place attachment, tourist experiences, and ERBs in Qianshan Mountain, a 5A scenic spot in China. Partial least squares structural (PLS) equation modeling is used to analyze the data of 410 valid questionnaires. The results found that tourist experiences affect ERBs through place attachment. Nature bonding is the key factor of ERBs. The results are as follows: escape and aesthetics influence ERB through nature bonding; entertainment influences general ERB through place identity and nature bonding; education has a positive impact on general ERB through place identity and place dependence. Entertainment and education experiences partially affect place attachment. Place identity and nature bonding affect general ERB, but particular ERB is related only to nature bonding. The internal psychological mechanism of ERB is identified. In addition, mountain landscapes can be designed from the perspective of entertainment experiences, landscape aesthetic, leisure atmosphere and educational functions, so that tourists can spontaneously pay attention to environmental issues and engage in the practical activities of environmental protection.
