Flagship store opening is one of the most frequently reported retail news in which it is widely used to promote a new store opening. The purpose of this study was to explore the flagship stores on media reports. Flagship store cases were collected from the news article database of the largest internet portal in Korea. A total of 210 cases were collected and content-analyzed. Though various business types of flagship stores were observed, most were in fashion. The most common characteristic of the flagship cases was the location of the prime sites in a metropolitan city. Global luxury and designer fashion brands met most characteristics, but many flagship stores were not more than a brand-owned store. The flagship store term is emphasized with dramatic expressions and various promotional events for media interests and in turn for marketing communication effect.

With the dramatic increase in mobile traffic in recent years, some of the limitations of mobility management frameworks have magnified. The current centralized mobility management (CMM) strategy has various problems, such as a suboptimal routing path, low scalability, signaling overhead, and a single point of failure. To overcome these weaknesses in the CMM strategy, the Internet Engineering Task Force has been discussing distributed mobility management (DMM) strategies. The fundamental concept of a DMM strategy is to distribute the mobility anchors closer to the users. While the distribution of mobility anchors results in low-cost traffic delivery, it increases the signaling cost. To reduce this higher signaling cost, we propose a new DMM strategy applying the pointer forwarding technique. The proposed strategy keeps the existing tunnels and extends the traffic path as much as possible. In this paper, we analyze the performance of the pointer forwarding-DMM strategy and discuss its pros and cons.

Photoaddition reactions of aromatic carbonyl compounds with silyl thioketene acetals have been explored. The results of this study show that the acetonphenone react with dimethyl substituted silyl thioketene acetal competitively via either single electron transfer (SET)-desilylation or [2+2]-cycloaddition pathways to produce b-hydroxyester and oxetanes. In contrast, photochemical reactions of the benzaldehyde with dimethyl substituted silyl thioketene acetal mainly lead to the formation of oxetanes arising by [2+2] cycloaddition. A comparison of the results with those of silyl ketene acetal revealed that replacement of sulfur atom in ${\alpha}$-silyl donor substrate bring about dramatic changes in chemoselectivities as well as excited state reaction mechanism.

Effective information "query and retrieval" process is one of the fundamental problems in the field communication and information science and has become especially important due to dramatic increase in magnitude of information to be processed in modern era. Of particular importance at information exchange process, our study focuses on compositions of proper queries and retrieval of rural amenity resources. This particular task has been difficult because the rural amenity resources does not necessarily carry measurable traits and also contains huge amount of data. In this Letter, we propose an alternative approach to the architecture of the resource information system by use of a noble retrieval algorithm based on ontology. Test of efficiency and applicability of this new scheme was conducted, and it showed that this has possibility to be effective information retrieval process of rural amenity resources.

Rapid time variations of the mobile communication channel have a dramatic effect on the performance of multi-carrier modulation. This paper analyzed the bit error rate (BER) performance for multi-carrier code division multiple access (MC-CDMA) network, and derived the equivalent signal-to-total noise plus interference(SNIR) of MC-CDMA system in the reverse link, the performance of MC-CDMA/BPSK signal is evaluated taking into account the fraction of partial-band interference and interference power. and the effect of partial-band interference is comprehensively studied in order to further improve the Qos of multi-carrier multimedia system.

In this paper, a relay communication scheme for enhancing the WiMedia network performance by device's mobility is proposed. WiMedia protocol is suitable for the application that supports the real-time multimedia service in Ship Area Network since it supports high speed data transfer. However, the device's mobility is caused the dramatic change of link state and network topology, and is occurred the degradation of network performance. Therefore, a relay communication scheme for WiMedia network is proposed in this paper. The proposed technique can intelligently treat the change of link state, and solve the degradation of network performance.

Due to the dramatic development of the Internet, the ICT market has changed from a voice based services to data based services. Substitution and complementary dynamism has emerged from communication technology services such as the Internet, mobile phone, and telephone. This paper analyses diffusion patterns of communication technologies such as the Internet, cellular phones, and telephones in different country groups. We estimate modified logistic growth model using time series data for the years 1975-2002. As a result, it is possible to categorize country groups according to the patterns of diffusions. This research creates essential information to forecast demand for new services based on incumbent services as well as provide information on strategies for entering the network industry.

While dramatic shifts in the media environment underscore the emerging importance of structural approaches in media studies. political economists in Korea have failed to meet such demands. It is particularly noteworthy that their most serious weakness lies in economic theories. This paper aims to examine major problems in political economic approaches in Korea and suggest some research agenda and directions for the future. Above all, political economists need to scrutinize and elaborate both microscopic and macroscopic frameworks. On the microscopic level, they may learn tremendous implications from the "audience-commodity" thesis and recent debates on "information goods" among Korean economists. For the more macroscopic part, it is urgently needed to delve into mid-level issues that may illuminate specific ways the media capital operates: trends in the accumulation of capital, the influence of technological innovation, changes in the labor process, and the relations among production, circulation and consumption sectors.

Due to the dramatic increase in usage of smart phones, mobile applications offer a promising public communication channel to effect behavioral change in areas such as energy saving. For this, identifying relationships between applications and behavioral change would be useful for public institutions to formulate more effective public communication strategies. Based on a design science approach, this study examines the effect of design factors of public service-oriented mobile applications such as personalization, accessibility, and representation richness on users' cognitive and affective attitudes. Their effects on behavioral outcome are also investigated. The results of the analysis show that most design factors contribute significantly to the cognitive and affective attitudes of users. In turn, cognitive attitudes affect users' behavioral change in terms of energy saving, while affective attitudes are positively associated with the average usage time of mobile applications and behavioral changes in terms of energy saving.

The diffusion of OTT service has brought the fundamental changes in the value chain of the existing media industry. OTT service based on the public Internet has increased the number of subscribers by using dominant marketing capability, making the pay TV platform player's ability to connecting users powerless. This study examined the changes in the media market and pay TV industry in the USA due to the diffusion of OTT service and analyzed the changing strategies of media firms. The number subscribers of the expensive pay TV service in the USA has diminished, experiencing cord cutting and cord shaving due the diffusion of OTT. OTT players are changing the media market, showing the dramatic excellence in making original contents and distributing the newly released movies. Examination of the recent merger and acquisition cases of media firms tells that the investment in making original contents has increased in order to have the competitiveness in OTT business. The future media industry will be rapidly reshaped mainly based OTT service and strategic judgement is important to maintain the competitiveness of all media firms in the existing value chain of media industry.
