Digital image capturing technology has been making great progress recently, and we can now simply capture the color image by digital camera, flat-bed scanner of Photo CD system. A lot of professionals are instrested in the capability of Photo CD and other digital images in the printing and publishing industry. But these images were not processed a suitable image processing to use in the hard copy. In this paper we described a method of the digital enhancement processiing to use in the printing and publishing industry. Experimental result show that the described method was useful and valid for the digital image enhancement to use in the hard copy.

This Paper focused on use intention at affect variable of broadcasting digital switchover. The author assumed that the perceived usability and perceived availability, social influence of technology acceptance model(TAM) are likely to affect the technological acceptance of broadcasting digital switchover. The results of this paper significant affect on the use intention of Social Influence, Personal Characteristics, Digital switchover perceive.

A demand on the spatial data management has been rapidly increased with the introduction and diffusion process of ITS, Telematics, and Wireless Sensor Network, and many different people use the digital map that offers various thematic spatial data. Spatial data for digital map can manage to tile-based and feature-based data. The existing tile-based digital map management systems have difficult problems of data construction, history management, and updating based on a spatial object. In order to solve these problems, this paper proposed the data model for the feature-based digital map management system that is designed for feature-based seamless map, history management, real-time updating of spatial data, and analyzed the validity and utility of the proposed model.

In the past, the judicial circles in the Republic of Korea (ROK) were generous to the online copyright violations of computer software compared to other academic areas or offline violation. However, they started to reconsider such a practice since the FTA talks with some advanced countries began so that new laws had to be established, especially after the first round of negotiations with United States of America (USA) in 2006 during which they changed their views on the matter. Now it became possible to penalize digital copyright violations through lawsuits, and from March 1st, 2017, the court is expected to abolish the nonsuit system for teenagers. Thus, this paper has reviewed the ethical aspects involved in digital copyright protection and examined the possible alternatives, dividing them into three broad groups, before proposing a digital copyright protection curriculum for secondary education.

Color reproduction is one of the most important expression factors in digital printing. In this paper, an experiment was done where the characteristics of color reproduction in digital printing. The results could summarized as follows. The printing used device profile showed a color difference of less than printing used default value in digital printing. As a result of weighting color difference, a difference between color gamut of digital original and color gamut of printing, when transforming the RGB color space to CMY color space, a exclusion the gray revision. The solution is to optimize the color transformation by gamut mapping and gray revision.

Digital leader caught seat by modern's everyday life tool now by popularization of smart device such as Smart phone and Tablet PC. Therefore, desire of readers about electronic book practical use is increasing based on convenience and economic performance of electronic book. 1971, Michael S. Hart established Project Gutenberg to produced first electronic book because inputs American Independence Declaration Statement by computer and produce more electronic books. After that, an electronic book technology repeats several times development and American electronic book take is increasing rapidly. Sales volume of electronic books is dramatically increasing in Korea since digital device such as Smart phone and Tablet PC became popular. This research attempts to analyze factors influencing on shifting from paper book to electronic book. Results of this research proposed grounds for building business strategy. Finding is the factor of social influence is only significant to acceptability intention. It means user of e-Book enhance their acceptability intention along social phenomena.

New IIR digital differintegrators (differentiator and integrator) with very minor absolute relative errors are presented in this paper. The digital integrator is designed by interpolating some of the existing integrators. The optimum value of the interpolation ratio is obtained through linear programming optimization. Subsequently, by modifying the transfer function of the proposed integrator appropriately, new digital differentiator is obtained. Simulation results demonstrate that the proposed differintegrator are a more accurate approximation of ideal ones, than the existing differintegrators. Furthermore, the proposed differentiator has been tested in an image processing application. Edges characterize boundaries and are, therefore, a problem of fundamental importance in image processing. For comparison purpose Prewitt, Sobel, Roberts, Canny, Laplacian of Gaussian (LOG), Zerocross operators were used and their results are displayed. The results of edge detection by some of the existing differentiators are also provided. The simulation results have shown the superiority of the proposed approach over existing ones.

We analyze the digital marketing strategies of Rare Beauty, a cosmetic brand founded by Selena Gomez in 2020, focusing on inclusivity and mental health advocacy as core pillars of its brand mission. Through an in-depth review of the brand's website design, SEO performance, social media engagement, and online review management-the key elements of a firm's digital marketing activities-we reveal Rare Beauty's success in authentically connecting with diverse audiences and fostering brand loyalty. Our analysis uncovers noteworthy findings: while Rare Beauty excels in creating a mission-driven aesthetic across digital platforms, there are areas for improvement, particularly in enhancing user experience by improving website readability, refining the review filtering system, and expanding social media engagement. Optimizing technical SEO could further increase discoverability. We propose these recommendations to strengthen Rare Beauty's online presence and demonstrate how the brand's unique approach offers valuable insights for industry professionals aiming to integrate social values into digital marketing strategies.

This study describes the design and implementation of SHF band Downconverter Digital Satellite Communication. The SHF band Downconverter unit consists of PLDRO and Frequency converter. In Frequency converter, microstrip BPF and LPF designed through the pre EM simulation are implemented to minimize the unwanted spurious in Frequency converter. Through the pre-simulation analysis of space environment, the possibility of and minimized about the malfunction of equipment and we designed a reliable SHF band Downconverter through simulation for a TID according to the vibration generated during the launch and space radiation environment, and compared pre-simulation of main performance results to test results about main performances of SHF band Downconverter after production.
