Technological advances made with the development of digital technology and the Internet have led to the emergence and evolution of digital convergence - the integration of media and communications. This, in turn, has led to the creation of the representative broadcast and communication convergence business model (IPTV service). This study examines the consumption patterns and behaviors of IPTV service customers and explores the process of their continuous use of the IPTV service, thereby endeavoring to contribute to the diffusion of digital convergence services. To survey customers' continuous use of the IPTV service, this study first designs a research framework based on an examination of the existing literature on satisfaction, loyalty, and so on. In addition, research is conducted on the switching barrier of the method of consolidating customers' adherence to a given IPTV service by increasing the burden on them, thereby developing a final research model with which to attempt yet another heterogeneous approach. This enables not only an analysis of the causal relationship with antecedent variables but also a measurement of the explanatory contribution of the antecedent variables' sub-variables.

The first purpose of this study was to compare the fashion zones and fashion brands on the floors in small and medium volume department store with those of big department stores within adjacent trading area. The second purpose was to find out similarity and differentiation of near-by department stores. The third one was to propose the future fashion marketing strategies of the department stores. The methods used were references, internet, field observation, and interview in 2002. Eight department stores within adjacent trading area were classified and analysed In "Gangnam division", "Seocho division＇. and "Youngdeungpo division". The results were as follows : Firstly, there was a low relationship between the degrees of brand equalization of each department store in the "Gangnam, Seocho. and Youngdeungpo division". Secondly, there was an alteration on the floor layout of each department store. It was layed out in a way that allowed for customers, who wanted to just purchase specific items, to go upstairs and look around several stores, which allowed for not only rise in the amount of sales but also offer the convenience of one stop shopping for the customers. Thirdly I proposed several marketing strategies such as lifestyle marketing, relationship marketing, and compile marketing which solves everyday life agenda. I also proposed the solution selling education to develop service education of salesperson. I finally proposed the overriding priority policy by sales record of each store.licy by sales record of each store.

For the effective operation of manufacturing system, FMS(Flexible Manufacturing System) and CIM(Computer Integrated Manufacturing) system are developed. In these systems, a machine tool is the target of integration in last 3 decades. In nowadays, the conventional concept of machine tools is changing to the autonomous manufacturing device based on knowledge-evolution through applying advanced information technology in which open architecture controller, high speed network and internet technology are contained. In this environment, a machine tool is not the target of integration but the subject of cooperation. In the future, a machine tool will be more improved in the form of a knowledge-evolution based device. In order to develop the knowledge-evolution based machine tools, this paper proposes the structure of knowledge evolution in M2M(Machine To Machine) and the scheme of a dialogue agent among agent-based modules such as a sensory module, a dialogue module, and an expert system. The dialogue agent has a role of interfacing with another machine for cooperation. To design the dialogue agent module in M2M environment, FIPA-OS and ping agent based on FIPA-OS are analyzed in this study. Through this, it is expected that the dialogue agent module can be more efficiently designed and the knowledge-evolution based machine tools can be hereafter more easily implemented.

In order to go digital broadcasting in Korea, it is conducted various policies in the country which be expanded network, be increased digital broadcasting hours. And broadcasting stations in the country close down analog broadcasting until 2012. Moreover IPTV is a method of delivering broadcast television and on-demand, rich media content that uses an IP(Internet protocol network) as the medium. And an IP is regarded as a very favorable approach for the future "Medium for Digital TV". However It is not easy to replace the entire digital infrastructure. And there are some problems in the digital infrastructure for Digital TV(i.e. channel zapping delay). Moreover user require service. IPMG is to solve these problems. IPMG is digital converter that allows receive and transmit signal by using many kinds of medium for Digital TV. Moreover IPMG provides users a Network PVR service. In this paper we developing, manufacturing IPMG and analyze its performance.

In recent years, with the development of IT technology and mobile communication, the powerful communication function of the Internet will gradually eliminate the information asymmetry between supply and demand, and the third-party review website emerges as The Times require. Dianping.com was founded in 2003. After a few years of development, it has become an independent third-party consumer review website worldwide. One of the reasons for such great success is corporate culture, which plays an important role in human resource management. The competition of enterprises is not only the competition of products and cost advantages, but also the superior enterprise culture presented to customers in the international environment. The competition between third-party review sites has been very fierce. In just a few years, many foreign third-party review websites went public and made profits, but some domestic start-ups went bankrupt due to the lack of a good business model and corporate culture. A good business model is particularly important. Taking dianping.com as the research object and combining with the business model of the company, this paper studies the unique corporate culture of dianping.com, hoping to help the company through the investigation and research of this paper, so as to improve the company in the future. And put forward a certain practical significance and value.

In this paper, we propose the method to improve the performance of the antenna system that contains three bands, such as Lte3G, WLAN and Lte4G. This antenna has an advantage that can cover the three different frequency bands 2.1GHz, 2.4GHz and 2.6GHz through one antenna design. The design and simulations are done using CST Microwave Studio 2014 program. The antenna is designed by using the FR-4 (lossy) substrate with the dielectric constant of er=4.3 and dielectric loss tangent 0.025. The substrate dimensions are the following; Thickness[h] is 1.6mm, Length is 90mm, and Width is 40mm. The ground is designed by using the PEC material with h=0.035mm. The patch is designed by using the copper with h=0.035mm. In the near future, we will fabricate the antenna, which we have designed, and then apply this antenna to the mobile communication system. And we will test this mobile communication system for the diverse environments.

While the Internet has been used to galvanise people for the collective good, many have voiced concerns over the noise and vitriol present online and polarisation. In Singapore where the government regulates traditional mainstream media such as print and broadcast, the online space has been described as a "Wild Wild West" rife with rumours, untruths and misinformation. Such developments do not only exert a potential negative effect on the deliberative nature of public discourse but also skew bias towards the online space, affecting the ability of online users to communicate with authority and power. This study seeks to examine the rationality of the cyberspace through using a new "rationality" framework to analyse political discourse online. Comprising objectivity, emotionality and partisanship, the rationality framework was applied to a content analysis of 197 blogs with political content in 2014. The analysis indicated that the online political space was not the Wild Wild West that it was touted to be with significant levels of objectivity and non-partisanship. There was a stark absence of emotional discourse, and relationships were observed between bloggers' anonymity and rationality. Cognisant of academia's and policymakers' interest on the quality and effects of online discourse, the proposed analytical framework and the study findings hold implications for both developed and developing countries.

The current fast-growing Internet traffic is demanding more and more network capacity. Photonic packet switching offers high-speed, data rate/format transparency, and configurability, which are some of the important characteristics needed in future networks supporting different forms of data. In this paper, we define that optical backbone networks for IP transport consist of optical packet core switches and optical fibers. We propose a multi-link photonic packet switch managing as single media which unifies the whole bandwidth of multiple wavelengths on the optical fiber in the WDM optical networks. The proposed switch uses optical packet memories of output link equally as well as using the WDM buffer. So it cuts down the required number of buffers and realizes of the optical packet memory economically.
