Over the last two years, the advent of new technology has brought about the emergence of blockchain friendly cities and tourist destinations. Various cities and countries developed technology-based solutions to serve the common good that is effective and efficient. The two cities or rather called city-stated that are perceived as most blockchain friendly destinations are Malta (La Valetta) and Singapore. These two destinations widely adopted blockchain technologies and become a hub for blockchain enterprises and researchers. Accordingly, blockchain tourism has emerged over the past two years as a subset of tourism development. Malta adopted a highly positive and simulative environment for the blockchain based companies and attracted a significant number of business entities working with blockchain followed by capital investments, business people, researchers, and experts. The objective of this paper is to identify best practices related to Malta blockchain strategy and its relationship to the sustainable tourism development in order to identify key dimensions for the sustainable growth of this sort of the tourism while highlighting key resources and challenges.

The primary objective of this paper is to conduct a systematic literature review to analyse contemporary scientific literature to determine a list of blockchain IT system implementation critical success factors. Scientific literature is available for the critical success factors that are impacting implementation for IT projects in general; however, it is of scientific and practical importance to whether these factors and their influence change when it comes to blockchain projects and even to determine does some additional critical success factors impact the success of the blockchain information system implementation in the smart cities.

This document presents an attempt to determine guidelines for the implementation of the blockchain projects within smart city (SC) information systems (IS) to improve their security and sustainability through harnessing benefits of blockchain technology. Although available scientific sources are scarce a review of contemporary scientific literature and other available sources attempts to determine weaknesses of current IS within SC and to compare their vs benefits of the blockchain technology in order to show that blockchain technology can offer potential solution to weaknesses and improve SC IS and therefore the sustainability of the SC itself. However, this research only shows the need for such implementations and discuss what further research is required to provide a framework for the implementation of blockchain technology in smart cities.

Existence of the appropriate infrastructue is the major bottleneck on the way to a more efficient ebusiness on the Internet. Also, the basic infrastructure and the application domain have to be correlated for the best performance. These issues and more are the subject of this mini-track. The first part (with three presentations from MIT, Boston, USA, University of Patras, Greece, and UNAM, Mexico) covers the core issues in the infrastructure domains. The second part, with ten different panel contributions, discusses the issues in the domain of the infrastructure/applications correlation (prepared by the students of the University of Belgrade).The first paper to be presented comes from MIT, and is related to the Oxygen project. The goal of Oxygen project is to bring an abundance of computation and communication to users through natural spoken and visual interfaces, making it easy for them to collaborate, access knowledge, and automate repetitive tasks. Speech and vision, rather than keyboards and mice, provide the main modes of interaction in Oxygen. Oxygen rests on an infrastructure of mobile and stationary devices connected by a self-configuring network. This infrastructure supplies an abundance of computation and communication, which is harnessed through several levels of software technology tomeet user needs.The second paper to be presented comes from Patras, Greece, and is representing the HPLAB. This paper gives a comprehensive understanding of the role and importance of scatalogs in today's scommerce strategies. The main contribution of it is a systematic approach towards the classification and evaluation of * Proceeding of the IEEEIHICSS-35, Kona, Hawaii, USA, January 2002. platforms, tools and implementations used for building e catalogs for scommerce solutions. Bcatalog solutions are classified into three general models. These approaches represent the most common classification of scatalogs in everyday use. After a short evaluation of each model, the current state of the market is reviewed by reviewing a representative tool for each category.The third paper to be presented comes from UNAMthe largest university in Mexico. It describes several new clustering algorithms for nodes in a mobile ad hoc network. It is proposed to combine two known approaches into a single clustering algorithm which considers connectivity as a primary and lower ID as secondary criterion for selecting clusterheads. The goal is to minimize number of clusters, which leads toward dominating sets of smaller sizes (this is important for applications in broadcasting and Bluetooth formation). Paper also describes algorithms for modifying cluster structure in the presence of topological changes together with propositions for an unified framework for most existing and new clustering algorithm and a framework for generating random unit graphs with obstacles.Special value of this mini-track is the panel part to follow, which will feature short presentations in the form of tutorials.

Scrum is the result of evolution in product development originating from the Japanese management system and process improvement (kaizen) and the Toyota production system from middle of the 20th century. However, Scrum is not the end result but a constant evolution. The purpose of this paper is an attempt to add new knowledge to this evolution. There are numerous alternatives to Scrum process and rules, commonly called hybrids. It is important to be aware that one approach or process cannot be a solution for every software development project. The key is to find a balance between the processes and the people, policies and the principles, as well as focus on long-term or short-term goals, etc. This problem is one of the biggest challenges widely discussed in present-day scientific and industrial communities.
