In this study, the method to use the phase shift keying (PSK) communication technique in smart transmitter is presented. In nuclear applications. smart transmitters for various parameters are expected to improve the accuracy of measurement and to reduce the load of calibration work. The capability of communication in field level is the most important merit of the smart transmitter. The most popular method is using of digital and analog techniques simultaneously - transmitting measurements from the field at 4∼20mA while modulating the current to carry digital information in both directions over the same twisted pairs. Conventional smart transmitters use the frequency shift keying (FSK) method for digital communication. Generally, however, the FSK method has the speed limit at 1200 bps. Amount of information to transmit becomes increasing as the processing technique is improved. The PSK method is noticeable alternative for high speed digital communication, but it has non-zero DC component. In order to use the PSK method in the field transmission with smart transmitter, the method to remove the DC component is studied in this work.

This study was carried out to identify the impact of EU GDPR on international trade amid the ongoing digital trade liberalization. To do this, we first looked at the current trend of digital trade liberalization, the role of data in it, and the trade-restrictive elements of EU GDPR. This allowed us to identify the negative impact of GDPR on free trade. It then conducted an interview survey on Korean companies operating in the EU to verify the conclusions reached. The result of this survey showed that the level of GDPR risk perceived by Korean firms was very low compared with those of American, Japanese and Chinese firms. In particular, the impact of GDPR is not clear for Korea's SMEs. It can be assumed that the reason for this is that Korean SMEs are not using data as a major business tool while the capability of SMEs is sufficient to cope with GDPR. In this regard, the government's appropriate policies and further research for SMEs are needed.

In today's highly digitized landscape, securing digital communication is paramount due to threats like hacking, unauthorized data access, and network policy violations. The response to these challenges has been the development of cryptography applications, though many existing techniques face issues of complexity, efficiency, and limitations. Notably, sophisticated intruders can easily discern encrypted data during transmission, casting doubt on overall security. In contrast to encryption, steganography offers the unique advantage of concealing data without easy detection, although it, too, grapples with challenges. The primary hurdles in image steganography revolve around the quality and payload capacity of the cover image, which are persistently compromised. This article introduces a pioneering approach that integrates image steganography and encryption, presenting the BitPatternStego method. This novel technique addresses prevalent issues in image steganography, such as stego-image quality and payload, by concealing secret data within image pixels with identical bit patterns as their characters. Consequently, concerns regarding the quality and payload capacity of steganographic images become obsolete. Moreover, the BitPatternStego method boasts the capability to generate millions of keys for the same secret message, offering a robust and versatile solution to the evolving landscape of digital security challenges.

The domestic fashion industry is not able to exceed the level of fashion that exists in advanced countries due to the relatively weak design competitiveness and the differentiated capability of product development. In order for the domestic fashion industry to become a growth industry that is valued in the world market of infinite competition, a step-by-step support system that can demonstrate and maintain the creative ability of designers is needed. Therefore, this study proposes a template - based 3D virtual fashion technology and a digital fashion platform based on it. The proposed template - based 3D virtual fashion technology is designed to clearly communicate the intention of designers and to be able to instantaneously view the results, thereby reducing the time and cost of producing prototypes. In addition, the digital fashion platform based on the template is designed as a collaborative platform based on idea sharing, which dramatically improves the process of confirming the prototype and initiating the product planning and manufacturing stages. This new technology can contributes to the formation of a business environment and a new area within the existing fashion industry and can be utilized for the development of the fashion industry in the future.

The police, as an advance guard for performing governmental functions, should conduct their duties to protect lives, physical bodies, and properties in the nation against various kinds of crimes, prevent from a public risk by detecting a factor that can menace public safeguard and public order and suppress it when a risk factor occurs. Practically it is impossible to protect lives, physical bodies, and properties in the nationprovided that social stability is not taken as security. The roles of the criminal investigation police that take a countermeasure to prevent a risk in prior by detecting hindrance factor of social stability and process any occurred crime in conformity with pertinent laws could control a successful performance in each of the police activities themselves. The study assumes that the organizational capabilities of the criminal investigation police exercises a significant influence upon organizational concentration. In spite of the fact that it is natural that the organizational capabilities of the criminal investigation police exercises a significant influence upon organizational concentration, until now it is very deficient in studies of this field. It is a viewpoint that an organizational concentration would be improved when a capability of the organizational staff will be improved, they would have a targeting capability for sharing organizational goals and vision and a systematic capability would be supported by the dimension of the criminal investigation police. The study was aimed to deduce a developmental method for the criminal investigation police by conducting an analysis on the impact of the organizational capabilities of the criminal investigation police upon organizational concentration that it suggest method that the criminal investigation police will make a contribution for maintaining a social order.
