This paper presents a new technique to generate the 1-bit signal by decoding Pulse Width Modulation (PWM) signal to a binary file before programming onto the ROM. Since each PWM signal requires only 1-bit digital signal, PWM signal and other forms of digital signal related to multi-bit can be simply generated. The results demonstrate that using this new technique to generate the PWM signal can simplify the process and hardware complication. Moreover, the signal's data and frequency can be easily modified by programming the data onto the ROM and using the counter, respectively, which can reduce the size of the circuit and make the PCB easier.

The emerging technologies at the industrial level have deployed rapidly within the energy transition process innovations. The nuclear industry incorporates several technologies like Artificial Intelligence (AI), Machine Learning (ML), Digital Twins, High-Performance-Computing (HPC) and Quantum Computing (QC), among others. Factors identifications are explained to set up a regulatory framework in the digitalization era, providing new capabilities paths for nuclear technologies in the forthcoming years. The Analytical Network Process (ANP) integrates the quantitative-qualitative decision-making analysis to assess the implementation of different aspects in the digital transformation for the New-Energy Transition Era (NETE) with a Nuclear Power Infrastructure Development (NPID).

A new breed of universities equipped with student-centered education programs and advanced digital technologies is changing the face of higher education. "Flipped learning" is heralded as a new model of education, yet its effect is underexplored. The purpose of this study is to provide evaluation criteria to assess and understand the merit of student-centered education programs and apply them to actual cases. Discussion on the nature of knowledge, its production mechanism and system, and possible contribution of digital technology to user-centered programs are discussed to produce five key criteria; initiative of students, interaction in class, interaction in field, customization of courses, and automated personal service. They are applied to evaluation of Minerva and Ecole 42.

A new high efficiency and low profile on-board DC/DC converter for digital car audio amplifier is proposed. The proposed converter shows the continuous input current, no DC excitation current of the transformer, the minimized electro-magnetic interference (EMI), no output inductor, and the low voltage stress of the secondary rectifier diodes. The 60W industrial sample of the proposed converter is implemented for digital car audio amplifier and the measured efficiency is $88.3\%$ at nominal input voltage.

In this paper we consider the Digital Multimedia Broadcasting (DMB) Service that starts recently in Korea and gains popularity. DMB makes it possible to watch high quality TV programs while we are in motion. The service provider or the service researcher are interested in the factors that influence the user's choice of new service such as DMB. Understanding the factors make them create the powerful marketing strategies and develop the new service or product that is attractive for users. We therefore find the factors influencing the user's choice of DMB service, and propose a model for analyzing the relationship between the factors and the intention of buying. The model is based on the Technology Acceptance Model (TAM). We extend the TAM by adding factors including functional attributes of DMB service. We survey the significant functional attributes influencing the intention of buying by using the proposed model.

Domestic digital signage industry has been growing in line with the Internet and intelligent devices like smart phones. However, policies for digital signage need to be supplemented because existing policies are only focused on regulations for outdoor advertisements. Moreover, while digital technologies have been developed, there are few contents technologies to support the digital technologies. In this context, this research aims to identify the problems in relation to the domestic digital signage industry and seek for measures to solve the problems. Various case studies and literature review were conducted to identify problems in terms of policy, technology and service, and measures for revitalizing the digital signage industry were suggested. The research is expected to help digital signage to serve as new convergence media available for customization targeting and user participation.

New space concept is gaining attention by the change of information and digital technology. It is called a concept of ubiquitous space which is united physical space and digital space. A united into a new space which is called ubiquitous space. It is an emerging concept of new era which is already applied in some part of our daily life the advanced. The advanced technology can help people to realize ubiquitous space including u-health care. Through analysis of characteristics of u-health care space, I am going to suggest new concept of ubiquitous space which is called u-space. It can make change of conventional health care space to vitalized new space and help people's life to be affluent.

Digital technology is recognised as a generalized technology in the media industry, therefore there is an opinion which shows that the markets for its old media will be replaced by new media. However, some researchers have confirmed that the printed media which has a long historical background will be continuously selected by the audiences. As going through the historical background of the printed media, it has been challenged by the freshly created media. And traditional printed media does not disappear as the challenge of new media. As the challenge of new media, the printed media will show the new future of the printed media itself and its market as well by the transformations through the acceptance and merging the new technologies.
