Hybrid Satellite-Terrestrial Communication Networks for the Maritime Internet of Things: Key Technologies, Opportunities, and Challenges

With the rapid development of marine activities, there has been an increasing number of maritime mobile terminals, as well as a growing demand for high-speed and ultra-reliable maritime communications to keep them connected. Traditionally, the maritime Internet of Things (IoT) is enabled by maritime satellites. However, satellites are seriously restricted by their high latency and relatively low data rate. As an alternative, shore & island-based base stations (BSs) can be built to extend the coverage of terrestrial networks using fourth-generation (4G), fifth-generation (5G), and beyond 5G services. Unmanned aerial vehicles can also be exploited to serve as aerial maritime BSs. Despite of all these approaches, there are still open issues for an efficient maritime communication network (MCN). For example, due to the complicated electromagnetic propagation environment, the limited geometrically available BS sites, and rigorous service demands from mission-critical applications, conventional communication and networking theories and methods should be tailored for maritime scenarios. Towards this end, we provide a survey on the demand for maritime communications, the state-of-the-art MCNs, and key technologies for enhancing transmission efficiency, extending network coverage, and provisioning maritime-specific services. Future challenges in developing an environment-aware, service-driven, and integrated satellite-air-ground MCN to be smart enough to utilize external auxiliary information, e.g., sea state and atmosphere conditions, are also discussed

Technology Advantage and Trade: Home Market Effects Revisited

According to conventional home market effects, free trade tends to shrink the market share for the smaller economy in the differentiated manufacturing goods, and in the extreme, leads to a complete hollowing out of the industry. In departing from the original Helpman-Krugman modeling assumptions behind the home market effects, we introduce technology differences between trading partners and prove that the home market effects will be offset and will even reverse if the small economy has better technology than the other country. We also prove that even with identical country size, the intra-industry trade addressed in the existing literature may not occur; it will occur only if the technology differential lies within a certain range that is positively affected by the level of transport cost.Home market Effects, Country Size, Technology Differential

OE-6 Building a Personal Brand on Social Media from Experiential Marketing Perspective - A Case Study on Indonesia’s Fashion Instagrammers

Instagram enhances online presence and identity, and allows more effective interaction not only for personal reasons, but also for business purposes. Experiential marketing is a new marketing concept that focusing on creative and innovative ways to appeal customers' senses, feelings, intellect, curiousity and self image rather than to rational, utilitarian notions of value. This paper aims to study about how the certain personality could build up their personal brand with Instagram as their main media from the experiential marketing view with the Analytical Hierarchy Process. Instagram fashion personal brands in Indonesia were the main source of the data collection. By the research, Sense factor is the most important strategic experiential module factor as in its relation with notable visual strength of Instagram. To be able to apply the Sense as a strategic experiential module, the consideration about tactical and practical factors are required. The 5 most important tactical factor is the Visual Elements factor, in which is about producing vivid content, Personality, a factor in terms of showing one true self, Relationship factor related to things about managing and maintaining relationships between stakeholders on Instagram environment, Signature, the factor about showing their own brand DNA, and Verbal Elements, the factor about communication in form of words. For practical factors are Image, by the image processing results and image taking directions, Apparel, with clothing combinations, style and brands, Authenticity, by being one true self, Caption, with the wording on every posts, and Brand and Followers, as brand to create a link or connection. As the implications, the fashion personal brands as the influencers could apply the key to draw attention from the audiences and make an impact to fashion enterprises in Indonesia

Challenges in Developing Applications for Aging Populations

Elderly individuals can greatly benefit from the use of computer applications, which can assist in monitoring health conditions, staying in contact with friends and family, and even learning new things. However, developing accessible applications for an elderly user can be a daunting task for developers. Since the advent of the personal computer, the benefits and challenges of developing applications for older adults have been a hot topic of discussion. In this chapter, the authors discuss the various challenges developers who wish to create applications for the elderly computer user face, including age-related impairments, generational differences in computer use, and the hardware constraints mobile devices pose for application developers. Although these challenges are concerning, each can be overcome after being properly identified
