As the Ubiquitous times approach, an interest regarding a Ubiquitous sensor network to be the only during key technology is rising. Currently, The fast development which radio communication technique is creating new services from the industry sector which is various from convenient characteristic and the ease characteristic side. Specially, rise and development of the radio communication technique which is various from environment monitor ring field makes to be improved about sharp curtailment of establishment and logistics relation expense, and collection period of the data which occurs real-time from site, reliability and delivery characteristic. But continuous application and the success about the environment monitor ring field of radio communication technique will be able to trust And It is important to provide time information which is appropriate real-time.

Radio base stations, which are widely distributed across large areas, have many difficulties in managing them. Unmanned radio base stations in remote mountains are having a hard time accessing them in case of emergencies. Major telephone service providers only remotely control incoming and outgoing information and local small business partners responsible for maintaining actual facilities do not possess such technologies, so they are each checked during field visits. In this study, in order to monitor temperature, humidity, fire condition, and power operation at a wide range of radio base stations, real-time monitoring is carried out at the office of Klaus server through real-time monitoring.

This paper describes the digital back-end system for getting the data to analyze the user observation mode by digitalize the analog data after receiving the space radio using the radio telescope, The received analog data will be digitalized by high-speed sampler with 1 Gsps for 4 channel frequency band of millimeter wave, and the digital data will be transported through the fiber-optic digital transmission system and WDM(wavelength division multiplex) to observation building, The wideband digital FIR(Finite Impulse Response) filters analyze the data for user observation mode to record the data in high-speed recorder with 1 Gbps. In this paper, we introduce the overall system configuration and features combined by various information and communication technology in radio astronomy briefly, which will be adopted by KVN(Korean VLBI Network).

The right to the spectrum frequency and orbit is required for the broadcasting by satellite, whether the broadcaster might be given any license or authorization for the broadcasting. The reason is that the ITU Convention and Radio Regulation provide very specific and detailed rules regarding the utilization of the frequency spectrum and orbit. Outstanding issue arises as to the implementation process of the rules of international character. Domestic implementation of the Radio Regulation, in the way of letter to letter should be discouraged when the competitiveness of domestic industry vis-a-vis foreign competitor is taken into account.

In cognitive radio networks (CRNs), the computational complexity of resource allocation algorithms is a significant problem that must be addressed. However, the high computational complexity of the optimal solution for tackling resource allocation in CRNs makes it inappropriate for use in practical applications. Therefore, this study proposes a power-based pricing algorithm (PPA) primarily to reduce the computational complexity in downlink CRN scenarios while restricting the interference to primary users to permissible levels. A two-stage approach reduces the computational complexity of the proposed mathematical model. Stage 1 assigns subcarriers to the CRN's users, while the utility function in Stage 2 incorporates a pricing method to provide a power algorithm with enhanced reliability. The PPA's performance is simulated and tested for orthogonal frequency-division multiplexing-based CRNs. The results confirm that the proposed algorithm's performance is close to that of the optimal algorithm, albeit with lower computational complexity of O(M log(M)).

In this paper, we explore the historical development and revolutionary impact of music in mass media across various forms, including radio, television, film, and digital platforms. The evolution of music in mass media reflects significant technological and cultural shifts over the past century. From the early days of radio to the advent of digital streaming, music has played a crucial role in shaping the types of mass media. Early radio broadcasts in the 1920s relied on live performances and recordings to captivate audiences, establishing music as a central element of media content. The rise of television in the 1950s brought new opportunities for music integration, with theme songs, variety shows, and music videos becoming staples of TV programming. The film industry further revolutionized the use of music, with iconic scores enhancing cinematic storytelling and emotional depth. The digital revolution of the late 20th century introduced new formats and services, expanding access to music and transforming consumption patterns. Recently, streaming platforms and social media allow for personalized music experiences and direct artist-fan interactions. Through an analysis of technological advancements, this study highlights the integral role of music in enhancing narrative, evoking emotions, and creating cultural identities. We present our understanding of this evolution to provide insights into future trends and potential innovations in the integration of music with mass media, including the use of artificial intelligence and virtual reality to create immersive auditory experiences.

Textile industry of Domestic has beeb confronted with Free Trade, and Regional Trade Blocks. In addition, textile industry market is changing from the provider market-oriented to consumer-driven market. RFID is the core technology to correspond in the these environmental change. In this study, we reviewed characteristic and present condition of domestic textile industry and newest technology aspect of RFID. Also, we suggested application plan of RFID technology in textile industry through the analyzing RFID application case of domestic and outside the country textile industry. More precisely, it is propsed that tracking, inspecting and logistics management of raw materials or yarn in up-stream, and Development hysteresis and process management of textile fabrics in middle-stream sector, theftproofing or returning clothes and providing information of products in down-stream sector, through RFID Technology.

Recently, RFID(Radio Frequency IDentification) is observed with government and connection enterprises as the central figure. RFID utilizing radio is a technology that enable exchange of information sensing and recognize object. RFID is expected that the practical use limits widens by territory that can form vast market such as logistics management according to RFID's low-cost aggravation as well as usage of life and improvement of performance because present R&D is gone vigorously. Because RFID is possible application everywhere if it is various service industries as well as logistics, industry spot, manufactory and place that flowing of goods is, is used, and is becoming big limelight from society several territories.
