KMAS as a Tool for Dissemination of Agricultural Technologies in Nagaon District of Assam

Development of Agricultural and allied activities can be achieved through various approaches of Information and communication (ICT) tools. Kisan Mobile Advisory system (KMAS) is one of ICT approaches for dissemination of agricultural technologies to the farming community through SMSs. KVK, Nagaon created a registered farmers group and information related to crop production, insect pest control, dairy and poultry farming, fishery and other marketing related information was sent to users in monthly basis for many years. A sample size of 100 registered farmers were selected for the study in order to examine the impact of KMAS for technology dissemination in Nagaon district. With the help of Pretested scheduled with Simple Random sampling data were collected and analyze in percent analysis. The survey showed that majority of the farmers found agricultural information as increase in knowledge (41.00%), partially applicable (73.00%). The overall impact of the KMAS was low About at 55 percent, medium at 38 per cent and high at 7 per cent. Further they suggested that messages on latest technologies should be served flowed by local language, voice messages.

Design of a coordinated cyber-physical attack in IoT based smart grid under limited intruder accessibility

The wider geographical span and deep penetration of information and communication (ICT) tools have increased the vulnerability of power networks to physical and cyberattacks. A coordinated cyber-physical (CP) attack is known to cause increased disruption in the internet of things (IoT) based smart grid (SG) operation as compared to a physical or cyberattack carried out in isolation. In this work, the design of a coordinated CP attack has been framed as a constrained optimization problem and solved using binary grey-wolf optimization (GWO) technique. Considering the increased dependence of network operations on state variables, the attack aims at hiding the impact of maximizing the deviation in the estimated state variables from the pre-attack scenario. The physical attack design considers the practical constraint of critical line inaccessibility to launch an attack. The two-stage attack formulation involves identification of an optimal network topology for maximizing the impact of physical attack, followed by launching an attack in the communication layer to hide the implication of physical attack at the control center. With the physical attack being masked, the control measures to minimize its impact are not executed, thereby leading to possible system shutdown. The validation of the scheme on IEEE 14, 30, and 57 bus benchmark power systems reflects its effectiveness in causing disruption in state estimation (SE) process with reduced attack cost.

IMPLEMENTASI ALGORITMA BRUTE FORCE PADA PENCARIAN DATA KEPEMILIKAN TANAH

Geographical information system is a system that combines elements on a map that is prepared to process data, analyze, and display spatial data to improve design. In the era of technology, information and communication (ICT) for organizations, agencies and public services is very important and needs to be implemented immediately. ATR / BPN in Jonggol village, Jabon, Ponorogo, still uses the manual method in processing certified land registration. The process of seeking, processing, and collecting certificate data requires a lot of time, causing services to be inefficient and effective and community satisfaction also decreasing. Therefore, a technology is needed that can facilitate service officers to search for certified land ownership data by implementing the brute force algorithm in the Geographical Information System for certified land ownership. The application of Algortima Brute Force in this geographic information system can run well, but if the text characters are long inputted, the system search process will take longer (if the text is short, the search can run quickly). On 10 keywords with different keyword or character lengths, the average search time was 0.06335 seconds.

GDP Modelling and Forecasting Using ARIMA. An Empirical Assessment for Innovative Economy Formation

This article reconsiders the developing of a new forecast model using the interrupted timeseries of the gross domestic product for the Republic of Moldova. The theme arises from a first need to redefine, economic growth in the context of increasing globalization but also the complexity of commercial transactions. The forecasting method used is based on ARIMA each model partly emphasizing the urgent need to redefine, the economic growth in the context of the Association Agreement (AA) with the EU, which includes a Comprehensive Free Trade Agreement (2014) but also future prospects of integration among the countries with an average degree of development. The technique used comes to bring novelty in the field of forecasting, as an alternative to the one which should be —, a simultaneous equations method and traditional VAR. The policy and practical implications of the results are the strengths. The limits are due to the high degree of risk and uncertainty, which is due to the low degree of real convergence of the economy, but also to other factors such as the regional context, the lack of openness of the economy, the diversification of exports and services. The degree of complexity arises from the adaptation and study of the chronological interrupted series 1967−2019 for the branch – information and communications, subgroup GDP, categories of resources, which themselves have specific asymmetries and nuances. The basic ARIMA equations are generally used in conjunction with three sets of assumptions regarding the formation of the gross domestic product, referring to the elasticity of aggregate demand or excess sensitivity supply in the goods and labour markets. Another hypothesis concerns the rigid wage and sticky prices, including deflation with an positive output gap only in the telecom market. Also, the salary is rigid, while the price level is adjusted based on the market of goods and commodities, so that the excess supply appears only in the labour market. Finally, in a third assumption, both markets are assumed to be mutually adjusted. The multipliers of fiscal and monetary policy, besides the conclusions that can be drawn about economic policy, are obviously different in these three assumptions. The article presents a synthetic model that supports the three particular sub-regimes of assumptions of a single adapted ARIMA model, namely the trajectory of New Keynesian Small and Closed Economy Model – a balance in the goods and services, the labour market and the national financial system. In conclusion, the model aims not only to redefine the area of macroeconomic forecasting but also to offer a future perspective of adopting combined techniques such as the Stochastic Dynamic General Equilibrium (K-SDGE) Model with sticky prices and wages – technique, but also the scenario method. This framework is appealing because it has straight forward model setup, transparent mechanisms, sharp empirical analysis, and multiple important applications such as rational expectations.

Duck curve leveling in renewable energy integrated grids using internet of relays

Power grids are undergoing deregulation, privatization, and decentralization worldwide. The smart grid allows the integration of clean power renewable energy technologies to the utility grid through mini, micro, and nano grids. Conventional centralized power grids used to rely on fossil fuel-fired power plants which are being replaced worldwide with solar, wind, small hydro, geothermal, biomass, wave, and alternative energy technologies. Installed solar and wind power generation capacity has surpassed 1300 GW in 2020. Solar and wind powers rise during the day and fall during the evening. Consumer demand increases steadily during the evening and peaks after sunset when solar generation becomes zero and wind power falls substantially. Decentralized smart grid faces duck curve limitation on the integration of renewable energy technologies as centralized utilities used to face the peak-hours issue. Smart grid operators have no effective solution of load peaking after sundown except keeping fossil fuel-fired plants on standby to ride through the duck curve. We present a solution to the duck curve problem by integrating smart load shedding devices in micro and nano grids to adjust their demand frugally during peak hours to support the national grid. Information and communication (ICT) technologies that enabled the internet of things (IoT) have been attempted to facilitate smart load shedding in nano grids. ICT enabled voltage transformers (VT) and current transformers (CT) supply signals to heuristic rules based multifunction smart relaying system. Smart meters, instrument transformers, and status monitoring field devices generate a massive amount of data. The research designed an IoT and LabVIEW based software platform to carry out demand-side management. Under frequency (UF) and under-voltage (UV) relaying functions were used to conduct load shedding in nano grids. This nanoscale demand-side management experiment paves the way to ride through utility-scale duck curve setback. This PT/CT data based economic solution performs at nanoscale same as ABB PML 630 load shedding controller. This UF and UV relaying based multifunction relay starts shedding loads when frequency falls below <1% and voltage below 10% of rated values. Our load shedding scheme has successfully functioned on nanoscale 5 kW system. The future study section proposes to integrate big data technologies in-home energy management system (HEMS) through extract, transform and load (ETL) pipeline to import data from PT/CT and circuit breakers (CB) integrated smart meter to transform it according to requirement by loading data into Hadoop “big data” processing platforms for utility-scale load management with help of day-ahead load and weather-dependent renewable power generation forecasting techniques.

The Level of ICT Infrastructure as a Factor of ICT Integration in Greek High School Science Teaching

This paper examines the extent to which the level of technological equipment affects the integration of the Information and Communication Technologies (ICT) in Greek high school science teaching. The limited ICT infrastructure environment, with only one computer‑projector system available and access to the internet (“PC‑VP” environment), is compared to the high level ICT environment (“1:1” environment) where, in addition to the computer‑projector system, each student has access to a computer and the internet. It is a study relying on a relatively small dataset derived from student answers to a questionnaire aiming to determine the degree to which some of the “expected” ICT benefits reach the students. The level of ICT integration is judged by the degree to which the ICT benefits reach the students. That is, the more the ICT benefits reach the students, the better – or the greater ‑ the ICT integration is. The participants were eighty‑nine, 14‑year‑old students who belonged in four different classes and the teacher who taught Physics in those classes. The SPSS non‑parametric "Man‑Whitney U Test" test was used to compare the statistical distributions of student answers. The results show that, when the applied teaching approach is used, the ICT integration is equally successful in both environments. This questions the idea of investing in “1:1" environments in the Greek public schools where less student centered and inquiry oriented teaching approaches are the norm. It also highlights the importance of the specific teaching approach as an ICT integration tool in “PC‑VP” environments that still exist in most Greek schools.

Blockchain for Development in the Era of the COVID-19 Pandemic

In the context of Informationand Communication Technologies (ICT) for Development (ICT4D), several efforts have been carried out over the last decades to help developing countries address their challenges. In times of a pandemic, such as the COVID-19, several of these challenges gain higher priority in development as they may become unmanageable with the developing world's resources. Blockchain is a disruptive technology that could potentially enable the sustainable addressing of some of them, and COVID-19 offers a unique and timely opportunity to operationalize it. Driven by the research question “In what areas can Blockchain help address development challenges during a pandemic?” we aim to understand its applicability in addressing crucial social problems in developing countries. While the literature analysis points towards several promising areas, there are also significant concerns that need to be understood and carefully addressed when considering Blockchain in the context of developing countries. The critical discourse in this work is expected to benefit a wide variety of technology, policy, and research stakeholders.

A BLENDED LEARNING IN ICT USED FOR IMPROVING ENGLISH LANGUAGE TEACHING

The technology of information and communication (ICT) has evolved in the sector of education. Many elements have dramatically changed exponentially over the past three decades. It can modify and simplify the development of learning activities. Thus, Google Classroom will provide a blended learning platform in the education aspect. Google Classroom provides various things simpler for teachers to conduct learning practices effectively and efficiently, not the expected learning just in class, but even outside the classroom. It is revolutionizing schooling, thus the combination of mixed-method learning is also needed by each school. The advent of blended is among the most significant outcomes of the revolution. Learning which incorporates the essence of face-to-face and ICT use is needed in the era of 4.0. This article discusses existing theories, and empirical evidence relating to the essence of blended learning and Google Classroom in ELT. This research is used to create teachers’ broad mind widely to the use of Google Classroom as the blended course in English Language Teaching.

Varying degrees of boundarylessness? The careers of self-employed and directly employed ICT professionals in the UK and Germany

Despite growing interest in the influence of social and institutional settings on the nature of career trajectories, research into comparative differences in boundaryless careers is scarce. Informed by the Varieties of Capitalism approach, which emphasizes the embeddedness of employment practices within discrete types of capitalist market economy, and based on rich qualitative data from in-depth interviews with 32 self-employed and directly employed information and communications (ICT) professionals based in the UK and Germany, we investigate variation in their experience of, and attitudes towards, boundaryless careers. The research findings provide scant evidence that ICT professionals embrace boundaryless careers, despite working in a sector where positive engagement with boundarylessness, if it is going to be found anywhere, should be evident. The findings also point to cross-national differences; directly employed ICT professionals based in Germany are more concerned about the insecurity than their UK-based counterparts. In highlighting the complex and subtle influences on how boundaryless careers are experienced and understood, the research builds on existing work which both attests to the importance of context in influencing boundarylessness and its consequences and questions an overly crude distinction between ‘bounded’ and ‘boundaryless’ careers, to emphasize the value of an approach which is concerned with understanding comparative variation in the degree of career boundarylessness.

R&amp;D Investments in the European ICT sector: Implications for Business Performance

Abstract Background A significant share of business innovation arises from information and communication (ICT) sector. Business investment into research and development (R&amp;D) activities can be seen as an important basis for innovation, which can further lead to better economic performance. This can be especially true for the ICT sector. Objectives The paper examines the share of the ICT sector on innovation and the total R&amp;D expenditure in selected European countries. Furthermore, our aim is to test the potential positive correlation between R&amp;D expenditure, productivity and the value added in the sector. Methods/Approach The goals of the paper has been tested by empirical data analysis using the pane regression analysis. We examined panel data for 24 European countries in the 2008-2016 period. Results The highest share of business R&amp;D expenditure in ICT has been captured in Nordic countries. Firms in ICT appear to be innovative above the average and represent a significant share in the total business R&amp;D expenditure. Conclusions We found a positive correlation between R&amp;D expenditure and both value-added and apparent labour productivity in the ICT sector. We believe that this could be to some extent attributed to the innovation of products and processes. Hence, the government support in the form of R&amp;D tax incentives can be also beneficial for the economic performance of ICT firms.

Trajectories of Teacher Traits: Professional, Administrative, and Social Roles

Teaching in higher education has undergone numerous paradigm shifts from teacher-centred authoritative to learner-centredcritical and culturally responsive/relevant pedagogies. Further, single method-boundedness has been substituted by theintegration of pedagogies via eclecticism in the post-method contexts. Further, virtual learning and paperless classroom,which were not dreamed in the past, has become realistic because of the innovative practices in the domain of informationand communication technology in education in general and the pandemic situation created by COVID19 specifically. Theseshifts have sparked tremendous changes in the teaching field. Based on these presumptions, this article aims to envisageteachers’ multifarious roles to play and tasks to perform. To achieve this aim, I have adopted a document analysis methodthat lies within the typology of the qualitative approach. Moreover, I have found three main categories of teachers’ rolesincluding professional, administrative, and social. These roles present a portrait of wholistic teacher traits inside and outsidethe classroom. The study implies that teachers should be capable of negotiating their roles and tasks based on the contextsthey encounter.

Pendampingan dan Pengenalan Teknologi Berbasis Internet kepada Anak Berkebutuhan Khusus di SLB C Budi Daya, Jakarta Timur

A normal child who is not lacking in anything physical or psychological is the dream of all parents. A hope regarding this matter is something that is natural for anyone. It's just that, in reality these hopes cannot be realized for some people. One of them is the presence of children with special needs in their lives. Even though every child has their own uniqueness and potential. One of the children with special needs is an autistic child. Autism is a very complex developmental disorder in a long life that includes disruption in aspects of social interaction, communication and behavior as well as emotional disturbances and sensory perceptions even in motoric aspects. Very severe disorders of some disorders experienced by children with autism that is a disorder in the ability to communicate. The ability to communicate nonverbally for children in general can be obtained naturally, without the need to be specifically and continuously taught for a long and long time. But the situation will be very different from autistic children. Autistic children need a design and learning strategy and approach to improve their nonverbal communication skills appropriately. Along with this, the development of Technology, Information and Communication (ICT) is inevitable. Most people think that the introduction and development of ICT knowledge is only for normal children. Through community service, the PKM team wants to share related developments in Technology, Information and Communication to children with special needs by using assistive devices and games specifically for children with special needs, especially children with autism. The implementation was carried out at SLB C Budi Daya, Cijantung, East Jakarta on 14 and 17 September 2018 ago.
