Like other new generation information technologies such as IoT, big data, AI, and cloud, cryptocurrency and blockchain became buzz words in both industry and academia due to their advantageous features. With the features like decentralization, transparency, immutability, blockchain technology became more famous and is emerging in almost all fields like banking, education, healthcare, government, and real estate. Blockchain technology was introduced in the year 1991. It came into existence after this technology was created for bitcoin, a digital cryptocurrency by Santoshi Nakamoto in the year 2008. Since then, the blockchain is evolving rapidly. Even though blockchain usage is in high demand in all the sectors and it has received attention from many international organizations, most of the people lag in knowledge of blockchain technology and Cryptocurrency and how exactly they work. This chapter explores more in detail what blockchain technology is, how it works, and its applications.

Nowadays society is profoundly changed by technology, velocity and productivity. While individuals are not yet prepared for holographic connection with banks or financial institutions, other innovative technologies have been adopted. Lately, a new world has been launched, personalized and adapted to reality. It has emerged and started to govern almost all daily activities due to the five key elements that are foundations of the technology: machine to machine (M2M), internet of things (IoT), big data, machine learning and artificial intelligence (AI). Competitive innovations are now on the market, helping with the connection between investors and borrowers—notably crowdfunding and peer-to-peer lending. Blockchain technology is now enjoying great popularity. Thus, a great part of the focus of this research paper is on Elrond. The outcomes highlight the relevance of technology in digital finance.

Semantic technologies are evolving to reach a mature state. Given the importance of Information Technologies in general and Internet in particular to organizations worldwide, these technologies can provide enhanced functionality to both existing and future solutions. This chapter provides an overview of the use of semantic technologies in several application domains, namely: construction & real estate, customer relationship management, e-government, e-learning, environmental sciences, health domain, human resource management, Information Technology, manufacturing, media and tourism, and cultural heritage. More than a hundred references are provided to support the idea that semantic technologies are applicable to almost all areas of interest.


In the cryptocurrency era, Blockchain is one of the expeditiously growing information technologies that help in providing security to the data. Data tampering and authentication problems generally occur in centralized servers while sharing and storing the data. Blockchain provides the platform for big data and cloud storage in enhancing the security by evading from pernicious users. In this paper, we have discussed the exhaustive description of blockchain and its need, features and applications. Analysis of blockchain is done for different domains such as big data, cloud, internet of things and mobile cloud where the differences V’s are compared with big data and blockchain. SWOT (Strength Weakness Opportunities Threats) analysis is performed to address the merits and limitations in blockchain technology. The survey in aspects of data security, data storage, data sharing and data authentication through blockchain technology is done and the challenges are discussed to overcome the problem that leads in big data and cloud storage. The detailed comparative analysis proves that the blockchain technology overcomes the problems in big data storage and data security in cloud.

Проведен анализ требований к обработке больших данных с использованием технологии блокчейн, показано, что в ряде проектов эти технологии, несмотря на различие архитектур, можно использовать совместно. Поставлена задача создать в компьютерной среде модель, которая показывает принцип обработки больших данных о продажах недвижимости на основе децентрализованной платформы технологии блокчейн. Определены архитектура и характеристики контрактов для микросервисов распределенного приложения. An analysis of the requirements for processing big data using blockchain technology is carried out it is shown that in a number of projects these technologies, despite the difference in architectures, can be used together. The task is to create a model in a computer environment that shows the principle of processing big data on real estate sales on the basis, of a decentralized blockchain technology platform. The architecture and characteristics of contracts for microservices of a distributed application are defined.

This research explains the mysticism of mappadendang tradition in Allamungeng Patue Village, Bone Regency, which is believed by the local community as a form of shielding from danger and can resist reinforcemen such as Covid-19 outbreak. This research is a descriptive study using qualitative method and an ethnographic approach. This research was carried out with the aim of identifying the mystical space in mappadendang tradition which was held in Allamungeng Patue Village. After conducting the tracing process, the researcher found that mappadendang tradition which was held in Allamungeng Patue Village, Bone Regency in July 2020 was not a tradition of harvest celebration as generally in several villages in Bone Regency, especially Bugis tribe, but mappadendang was held as a form of shielding from all distress including Covid-19 outbreak. This trust was obtained after one of the immigrants who now resides in the village dreamed of meeting an invisible figure (tau panrita) who ordered a party to be held that would bring all the village people because remembering that in the village during Covid-19 happened to almost all the existing areas in Indonesia, the people of Allamungeng Patue Village were spared from the outbreak. Spontaneously, the people of Allamungeng Patue Village worked together to immediately carry out the mappadendang tradition as a form of interpretation of the message carried by the figure.

This paper aims to bring into the ethical debate on covert research two aspects that are neglected to date: the perspective of the research subjects and the special responsibility of investigators towards their observers. Both aspects are falling behind, especially in quantitative social research. From a methodological point of view, quantitative forms of covert observation involve a great distance between the researcher and the research subjects. When human observers are involved, the focus is usually on the reliable application of the measuring instrument. Therefore, herein, a quantitative study is used as an example to show how the protection needs of both the observed persons and the observers can be met in practice. The study involved 40 student observers who covertly captured everyday conversations in real-world settings (e.g. in cafés or trains) by a highly standardised observation scheme. The study suggests that the anonymity of the research subjects and their trust in the observers are crucial for their subsequent consent. However, many participants showed only little or even no interest in the written information they were provided. Further, this study strongly emphasises how mentally stressful covert observations are to the observers. Almost all observers were worried in advance that the people they were observing would prematurely blow their cover and confront them. Role-playing and in-depth discussions in teams are good strategies to alleviate such and other fears and to prepare student assistants well for their demanding work in the field.

AbstractIn a world where articles and tweets are discussing how artificial intelligence technology will replace humans, including lawyers and their support functions in firms, it can be hard to understand what the future holds. This article, written by Alex Smith, is based on his presentation at the British and Irish Association of Law Librarians conference in Dublin 2016 and looks at demystifying the emerging technology boom and identifies the expertise needed to make these tools work and be deployed in law firms. The article then looks at the skills and expertise of the knowledge and information teams, based in law firms, and suggests how they are ideally placed to lead these challenges as a result of their domain expertise and their existing, well defined skills that are essential to this new generation of technology. The article looks at the new technical environment, the emerging areas of products and legal problems, the skills needed for the new roles that this revolution is creating and how this could fit into a reimagined knowledge team.
