Specification of downlink-fixed reference channel DL-FRC for 5G new radio technology

<p>The next generation for mobile communication is new radio (NR) that supporting air interface which referred to the fifth generation or 5G. Long term evolution (LTE), universal mobile telecommunications system (UMTS), and global system for mobile communication (GSM) are 5G NR predecessors, also referred to as fourth generation (4G), third generation (3G) and second generation (2G) technologies. Pseudo-noise (PN) code length and modulation technique used in the 5G technology affect the output spectrum and the payload of DL-FRC specification, in this paper quadrature phase shift keying (QPSK), 16 QAM modulation approaches tested under additive white Gaussian noise (AWGN) in term of bit error rate (BER) which used with 5G technology system implemented with MATLAB-Simulink and programing and, resulting of 1672, 12296 bit/slot payload at frequency range FR1 from 450 MHz-6 GHz and 4424, 20496 bit/slot payload at frequency range FR2 from 24.25 GHz-52.6 GHz, also determining subcarrier spacing, allocated source block, duplex mode, payload bit/slot, RBW (KHz), sampling rate (MHz), the gain and the bandwidth of main, side loop where illustrated.</p>

shift of lexicon in traditional technology system in Tolaki community at Konawe district of Southeast Sulawesi

This research discusses the lexicon used for traditional technology systems in the Tolaki community. Lexicon is a language component containing all information about the meaning and usage of words; the richness of words a language has. Lexicon runs into a shift due to certain factors such as changes in norms, culture, and environment caused by the development of science and technology. This research aims to analyze the level of shift and change in the meaning of the lexicon for traditional technology systems in the Tolaki community in Konawe Regency, Southeast Sulawesi. The method is qualitative descriptive. The data are taken from written sources, literature studies, by examining and recording some lexicons from the book “Tolaki Culture” by Abdurrauf Tarimana related to the lexicon in the traditional technology system of the Tolaki community. The validation of the data is then substantiated by questionnaire distribution in which the informants fill in lexicon data about agricultural technology systems and imply them in Tolaki language. The theory used is the lexical-semantic theory proposed by Pateda. The results showed that the lexicon for the Tolaki agricultural technology system is extinct and there is a shift in the lexicon.

Quality factors in technology system capability decision interest in transactions using mobile banking

The purpose of this study was to determine the effect of ease of use, transaction success rate, and technological system capability on trust and to determine the effect of ease of use, transaction success rate, technology system capability and interest in transaction using mobile banking. This research was conducted at PT Bank NIAGA which is located in Denpasar. The data collection technique used a questionnaire to 160 PT Bank NIAGA customers who were selected as samples. Data were analyzed by Structural Equation Modeling (SEM) with AMOS program. Ease of use, transaction success rate, and technology system capability have a positive and significant influence on trust and interest in transacting using mobile banking. This means that the better the ease of use, the success rate of transactions, and the capability of the technology system, the higher the customer trust and interest in transactions using mobile banking.

A Study on the Learner’s Satisfaction of on-line PBL classes in Korean College

The quick move to non-face-to-face education caused by the sudden attack of the COVID-19 led to many problems such as faculty’s burden and stress from the planning and designing of suitable on-line classes, technology system problems for both students and faculty and students’ complaints of the low quality of education. Especially Project-based learning (PBL) has more challenges because it is learners-centred and is usually done in face-to-face environment. The primary purpose of this study is to investigate the factors affecting the learner’s satisfaction of non-face-to-face on-line PBL classes in terms of interaction and learner’s factors during the attack of COVID-19 pandemic. The data Was collected through questionnaires, from 175 undergraduate students at S women’s university who took the on-line PBL classes. SEM (Structural Equation Model) was used for empirical test using SmartPLS. The results of the empirical analysis reveal that interaction and media utilization self-efficacy are likely to predict learner’s satisfaction. Keywords: COVID-19, On-line PBL class, Satisfaction, Interaction, IT self-efficacy, Motivation

<p>This paper aims to find out how the legal aspects of companies operating special rental transportation are regulated based on the Regulation of the Minister of Transportation (Permenhub.) of the Republic of Indonesia Number 118 of 2018 which is amended by Permenhub. Number 17 of 2019. Transportation is the movement of people or goods from one place to another by using a vehicle in the road traffic room. The information technology system-based transportation adapum is a mode of transportation in the form of legal entities and micro-enterprises or small-scale business actors connecting from one place of origin to one's destination, where the ordering method uses an information technology system and the amount of the fare is listed in the application. Companies in the form of legal entities in the form of Limited Liability Companies, BUMN, BUMD, and Cooperatives as well as micro business actors or small business actors established in accordance with the provisions of laws and regulations. The form of this special rental transportation company is not in accordance with Law Number 22 of 2009 and Article 79 of Government Regulation Number 74 of 2014 concerning the Implementation of Public Transportation.</p>

The use of modern television technology and its impact on increasing viewing of news programs on Jordanian television from the perspective of employees and technicians working in the news programs: استخدام التقنيات التلفزيونية الحديثة وأثرها في زيادة متابعة مشاهدة البرامج الإخبارية في التلفزيون الأردني من وجهة نظر العاملين والفنيين العاملين في البرامج الإخبارية

The study aimed to uncover the level of use of modern television technologies and their impact on increasing the watching of news programs on Jordanian television. The study used a descriptive and analytical approach, and the data were collected through developing a scale for the use of modern television technologies for news programs. The sample of the study consisted of (110) workers and technicians in news programs on Jordanian television, chosen by the available deliberate sample method. The results of the study showed that the use of modern television technologies increases the degree of television viewing, especially watching news programs. The study also showed that Jordanian television still uses old television technologies. The study recommended the necessity of transforming Jordanian television into the HD broadcasting technology system instead of the SD system and working on training employees on modern television technologies (infographic, graphics, audio effects, and visual effects).

Desertification and Its Control along the Qinghai-Tibet Railway

The Qinghai-Tibet Railway is a magnificent project in the twenty first century. However, the problem of land desertification has arisen during the operation of the railway. Many sections of the railway roadbed are buried by sand. The ecological safety along the railway and the safe operation of the railway have attracted worldwide attention. This chapter will focus on the current situation of desertification along the Qinghai-Tibet Railway, such as key desertification sections and the temporal and spatial characteristics of the occurrence of desertification. At the same time, it introduces the characteristics of the dynamic conditions of railway desertification and the source of sand material. It is divided into two parts: biological measures and engineering measures to introduce desertification control along the railway. The biological measures focus on the selection of Lolium perenne, Festuca sinensi, Elymus breviaristatus, Elymus nutans and Poa crymophila, and other alpine native sand-fixing plant materials. The engineering measures will introduce the railway desertification comprehensive prevention and control technology system that combines solidification, resistance, and transportation.
