The digital divide issue is re-emerging in step with the rapid progress of digital transformation. Recently, the discussion of the digital divide is expanding to the point that the difference in digital access and use competency deepens economic and social inequality and discrimination. Notably, the phenomenon of the exclusion and alienation of the elderly from society is a serious matter to be addressed. Accordingly, this research was conducted to provide practical help in minimizing the digital divide through its understanding among the elderly. To this end, both the accomplished capital accumulated and experienced in the course of life and their attitudes toward technology in relation to digital competence capital by the elderly were examined in three dimensions. This analysis was conducted using the results of the '2020 The Report on the Digital Divide'. The target group of the analysis comprised 653 seniors aged 65 and above. As a result of the analysis, digital competence capital among the elderly was affected by both various types of accomplished capital such as educational, income, social, and emotional capital and digital device use attitude. Based on this, this study proposed measures to bridge the digital divide among the elderly.

The purpose of this study is to investigate how level of digital information usage of the middle-aged or elderly people affects life satisfaction and whether social capital mediates the relationship between level of digital information usage and life satisfaction. In this study, we analyzed data of 1,661 people aged 55 or older from the 「2018 Survey on Digital divide」 by the National Information Society Agency. The SPSS 25.0 statistical package was used for the mutiple regression analysis and Baron and Kenny(1986)'s steps for mediation. The statistical significance of the mediated effects of social capital was verified by the Sobel Test. As a result of the analysis, the aged people have a higher life satisfaction when they are women and older, do not live alone, have higher levels of digital informatization usage and social capital. In addition, social capital also revealed to have a mediating role between level of digital information usage and life satisfaction. This shows that social capital needs to be considered along with the level of digital information usage as a way to improve life satisfaction of the middle-aged or the elderly people.

In this study, the relationships of factors influencing the ways alternative types of new digital products are accepted into the market will be structuralized. On the basis of previous research, it is assumed that customers intend to use alternative types of new digital products when they have a higher value than existing products. The consumer's feeling of attraction toward the product is another factor included in the evaluation of its quality. And the attraction of the products that the consumers feel is also included in the evaluation of the qualities of the product. The results of the study indicate first that a product's value affects its attraction, but not the usage intention of the customer. Second, the benefits of the product affect the customer's recognition of its value, while cost does not. Third, environment affects recognition by the customer of the product's attraction, while knowledge of the product does not. By structuralizing the factors that influence the customer's usage intention about alternative types of new digital devices, the causal relationships of the factors involved in the acceptance of new products into the market and their success can be comprehended.

The emergence of the new technologies, which are represented by multimedia and the internet, brings the tremendous change in respect of process, record, delivery, and transmission of the knowledge and information. The new digital contents made by these technologies help to improve the acquisition efficiency of the knowledge and information by directly and simultaneously stimulating humans' different senses. This paper concentrates on how the accumulated computer technologies such as multimedia and the Internet can be used to make the effective digital contents. This paper suggests four development method for the digital contents and gives the implemented example for each development method.

This study aims to present the framework for promoting active engagement of users in digital archives through social tagging. It analyzed the technological development involved with digital archives, and the user participation and engagement through social media. The analysis explored the aspects of social tagging in terms of communication, sharing and collaboration in digital archives. Based on the analysis and reviews, it developed the model of social tagging for user participation and interaction in digital archives. The study proposed the application of open and game platforms for promoting active engagement of users in digital archives through social tagging.

The National Library of Korea establishes an Act on Legal Deposit and Use for the Online Digital Products in 2007 and it is preparing an enforcement. The purpose of this study is to suggest rate base on legal deposit of digital products before enforcement of this bill. To reach the goal, this study reviewed the legal deposit acts on digital products in the world. Also the opinion of main stakeholders in this area was collected such as digital book publishers and music copyright association. In conclusion, this study proposed rate base of reimbursement for legal deposit of digital products.

Digital road map - which plays an essential role in giving accurate location of the vehicle, optimum route guidance, destination searching, and topographic feature query functions - is the most fundamental element of the vehicle navigation system. Unfortunately, there is not a nation-wide digital map in Korea such as U.S. TIGER fie, that is easily applied to digital road database production. Therefore, producing new digital road map is inevitable in Korea For establishing digital road map for vehicle navigation, this paper puts forth the necessary condition to stabilize the digital road map qualify, and to keep up the compatibility and the economical use. As a result, the standards of coordinate and map accuracy arc presented, and the Items and the structures of database arc decided.

This paper presents the implementation of IS-95 CDMA signal processor, baseband and Intermediate Frequency(IF) digital converter using Field Programmable Gate Array(FPGA) and ADC/DAC and frequency up/down converter IS-95 CDMA channel processor is generated the pilot channel signal with short PN code and Walsh-code generator. The digital If is composed of FPGA. digital transmit/receive signal processor and high speed analog-to-digital converter(ADC) and digital-to-analog converter(DAC). The frequency up/down converter consisted of filter, mixer, digital attenuator and PLL is analog conversion between intermediate frequency(IF) and baseband. This implemented system can be deployed in the IS-95 CDMA base station device etc.

In this work, two-dimensional FIR digital filter is designed and simulated using research and educational CAD tools. The two-dimensional digital filter consists mainly of one-dimensional digital filter and line memory. To speed up one-dimensional digital filter, multiplications are carried out on the basis of hardwired-shifting methods by the digital filter coefficients represented in CSD formats, while carry-save adder and Manchester adder are used in addition. It is found that the designed digital filter operates up to 30 Mhz in VHDL simulation and operates normally in IRSIM simulation for the layout made by Berkeley CAD tools.
