With the continued evolution of third-generation cellular systems and the introduction of 3GP P LTE, there is considerable progress for the new mobile wireless markets. Recently, 3GPP LTE standards are accelerated by mobile operators supporting LTE deployment and special working groups such as LSTI are working for LTE IOT and trials. In this paper, we introduce the current status of LTE activities in the mobile communications industry.

Purpose: The purpose of this study is to investigate the service quality factors in terms of customer trust, satisfaction and loyalty of the Korean telecommunication companies(SKT, KT, LG U+). Specifically, this study presents new business strategies of the each company, thereby pursuing the innovation for mature stage. Methods: To analyze the telecommunication service quality factors that contribute to customer trust, satisfaction and loyalty, this study conducted a survey targeting customers of each company. Using the data collected, the research model was built, and empirical analysis was performed through statistical processing to verify the model. Furthermore, the clarification of each hypothesis were held including the comparison analysis of each company data. Results: The results of this study are as follows; (1) When it comes to total dataset, all quality factors including trust, satisfaction and loyalty showed significant relationship, accepting every hypothesis. (2) However, for SKT and LG U+, empathy showed no significant impact on trust while the others showed significant effect. (3) Finally for KT, all service quality factors such as responsiveness, empathy, security, and customer enablement had a significant effect on trust. Conclusion: As the development of platform industry are intensified, telecommunication companies are required to manage service quality factors thoroughly, especially focusing on customer privacy and security.

On the base of IT growth, competition between countries for preoccupation of digital content market is keen. And it is prospected that the development of digital content industry will be more rapid with the base of telecommunication infra-structure(for example internet, digital broadcasting) which is the main channel for distribution of digital content. The bill of "Act for Development of Online Digital Content Industry", has passed the national assembly jan, 2002, and "Draft Blueprint for Developing Online Digital Content Industry(2003$\sim$2005)" was made on the base on that law feb, 2003. And we can find measures for protect the digital content manufacture in the laws such as "Literary Property Law", "Trademarks Law" and "law for prevention of unfair competition". On this study we suggested three measures to make digital content industry more profitable by the method of research of related law and industry survey.

Recently, under recognition that ubiquitous computing is core paradigm to build up a state of new knowledge information and to strengthen the competitiveness of domestic information industry, governments, enterprises, and institutes in United States, Europe, and Japan devote all their energies to develop technologies concerned. In Korea, the government presents ubiquitous technologies as a main part of the next generation growth industry, and also other governmental agencies and enterprises concentrate their energies on early fruition of ubiquitous society. Accordingly, as a foundation research to apply ubiquitous environment which emerged as a next generation high-end telecommunication technology effectively to construction field, this paper will discuss about element technologies to realize changing aspects of construction process under ubiquitous environment and information services by stages.

Various messages generated in vehicles are transmitted based on the wireless telecommunication which is a core technology of vehicle to everything (V2X). However, the hackers attack them upon penetration to the system and network to cause the generation of users' inconveniences for vehicular communication. Moreover, huge damage could be occurred in terms of physical and materialistic areas if the users in the vehicles were attacked in the communication environment. Therefore, this study was to design the safe communication protocol using hash tree technique in the V2X environments. Using hash tree technique, processes of issuing certificate and registration and communication protocol were designed, and safety analysis was performed on the attacking technique which is occurred in the existing vehicles. Approximately 62% of decrease in the capacity analysis was found upon comparative analysis of telecommunication processes with the system to issue the certificate which is used in the existing vehicles.

Standardization is essential strategic tool for a firm to preoccupy a market in the telecommunication industry. WTO TBT(Technical Barriers to Trade) makes importance of standardization greater in telecommunication industry. Therefore countries, not to speak of firms, recognize standards essential strategy to preoccupy markets. In this paper, we will analyze the patterns and study the case on standardization competition in the field of telecommunications.

This paper is about how to drive a Business Process Management(BPM) implementation project from selecting a target process to BPM deployment. For guidance of BPM implementation, LG CNS BPM Methodology and enPAM(Entrue Process Assessment Model) were used. This paper focuses on the methodology of process selection and presents a case study from the telecommunication industry. The enPAM consists of three major criteria in determining process priority for BPM system deployment: business impact, BPM adequateness and implementation feasibility. These three criteria can be easily modified for other telecommunication business just as we did to suit this telecom case. Moreover, it could provide useful ideas to companies that consider introducing a BPM solution for process management. Although we propose a comprehensive design methodology for selecting a proper target business process for BPM implementation, more work is still needed to extend the results for rigorous and practical method.

Electric and telecommunication industries are constantly striving towards miniaturization of electronic devices. Miniaturization of chips creates extra space on PCBs that can be populated with additional components, which decreases the heat transfer surface area and generates very high heat flux. Even though an air-cooling technology for telecommunication equipment has been developed in accordance with rapid growth in electrical industry, it is confronted with the limitation of cooling capacity due to the rapid increase of heat density. In this study, liquid-cooling heat exchangers with MPCM slurries were designed and tested by varying geometry and operating conditions. The liquid-cooling heat exchangers with 4-paths showed higher cooling performance than the others. The cooling performance of liquid cooling heat exchanger with MPCM slurries was more enhanced than that of the air cooling system. It's performance was also slightly superior to that of the water cooling system at the inlet temperature of $19^{\circ}C$.
