It is evidenced that the mass media can play an important role in communicating information to the public. Although some campaigns have failed to achieve success, application of mass communication principles should increase the likelihood of effectiveness. Specifically, campaign strategies should attempt to select message sources that are perceived as credible by the audience. In designing and disseminating messages, the quality of content should be emphasiged as well as the quantity of presencation. The context of message reception should be carefully considered. Selection of channels depends on the configuration of source, superior for most purposes. The crucial role of precampaign audience analysis should not be overlooked.

This study investigates the influences of the impulse buying tendency of consumers, apparel price and scarcity messages on purchasing behavior at the time of purchase on the internet. This study was comprised of 2 (impulse buying: high versus low) $\times$ 2 (price of Internet purchase products: high apparel price versus low apparel price) $\times$ 2 (scarcity message: quantity scarcity message versus time scarcity message) with three mixed elements. The subjects of this study were 400 college students in the Seoul and Gyeonggi area. A total of 95 students who had a high tendency for impulsive purchase and 104 who had a low tendency participated in the survey. Data are analyzed by factor analysis, T-test, and ANOVA. The results of this study are as follows. 1. At the time of group buying on the Internet, impulse buying tendency, apparel price, and scarcity message had a statistically significant interaction effect on consumer preferences. 2. At the time of purchase on the Internet, impulse buying tendency, apparel price, and scarcity message did not have a statistically significant interaction effect on the intention of consumers to make a purchase. However, there was a significant difference in the intention to make a purchase based on impulse buying tendency and apparel price.

In Twitter, a user can post a message below 140 characters on his/her account, and can also repost a message of other users who the user follows. The message posted by the user in turn can be seen and reposted by other users who follow the user, which is called Re-tweet (RT). While some messages spread widely, other messages have relatively less or no RT. What factors cause these quantity variances of RT originated from original messages? How can the messages become influential in online social networks? As an effort to answer the above questions, we focused on information vividness, message characteristics, and originator characteristics. In perspective of managerial implication, we expect that the findings of this paper will provide corporations with helpful insight on the Word-of-Mouth (WOM) effect for efficient and effective advertisements and communications when they send a message of new products or services through Social Network Services. In perspective of academic implication, we identify the effect of contents of a message on WOM, which has been dealt with by few social network researches.

Recently, wireless sensor networks(WSNs) technology has been considered as one of the most critical issues in the ubiquitous computing age. The sensor nodes have limited battery power, so they should consume low energy through their operation for the long-lasting lifetime. Therefore, it is essential to use energy efficient routing protocol. For this, we propose a location-based energy-efficient routing protocol which constructs the energy efficient route by considering the quantity of Energy consumed. In addition, we propose a route reconstruction algorithm to handle the disconnection of message transmission. Finally, we show from performance analysis using TOSSIM that our protocol outperforms the existing location based routing protocols in terms of energy efficiency.

The knowledge of the specialized fields has been changed rapidly in the both side of quantity and quality. A hyper media as a knowledge based system is so fixed in the linked media in mutual that we couldn't tell it information provision with the view of users. In this paper, we propose the way of offering intellectual and flexible information which is the same with demand in the side of user, selecting, searching and composing the hypertext at the point of user's view through the design of knowledge media system. Three concepts are used in order to challenge the knowledge media system : special document, agent system and ontology. The special document is a ensure that its activities are coordinated with those of the others within the community, providing a uniform control mechanism. Finally, ontology is a language for exchanging knowledgement, which is a message exchanged among agents to ensure the proper interaction among them. The combination of these three concepts is used to design the prototype of knowledge media system.

This study was aimed to analyze how images of information society were embodied in contemporary fashion design. To find out images of information society expressed in contemporary fashion design, this paper reviewed the characteristics of information society, and, found out six categories of contemporary fashion design in which the information society was expressed. Cyber environment causes techno style clothing which is characterized by the metallic or lustrous material and mechanical message. And interest in new materials increased significantly. Time-space compression makes the meaning of time and space change, therefore the past, present and future are coexist in the contemporary fashion design. The boundaries has loosed, so, heterogeneous materials and colors are used in fashion design all together. Variety and plurality affect expression of individuality and self-concept. Flexibility increased, so, soft and pliable clothing increased, too. Finally, quality of life is considered as more important value than quantity, so, luxurious look and zen style appear. Also, minimalism which is characterized as simplicity and purity affects the contemporary fashion design.

This paper examines the security vulnerability, demanded service, layering consideration for local area networks(LANs), and proposes a new key distribution system suitable to local area networks. the new key distribution system Is applicable to time quantum in encrytion key and then the time used arid the quantity of encryption message using the encryption key are limited. A system suggested in this paper can achive some higher concurrency of key and authentication of the opposite party. Even through a encryption key expose by reason of wiretapping of a frame unit, It has achived some more security and safety, because the contens of all traffic messages are not known.

${\mu}TESLA$ broadcast authentication protocol have been developed by many researchers for providing authenticated broadcasting message between receiver and sender in sensor networks. Those cause authentication delay Tree-based ${\mu}TESLA$[3] solves the problem of authentication delay. But, it has new problems from Merkel hash tree certificate structure. Such as an increase in quantity of data transmission and computation according to the number of sender or parameter of ${\mu}TESLA$ chain. ${\mu}TPCT$-based ${\mu}TESLA$[4] has an advantages, such as a fixed computation cost by altered Low-level Merkel has tree to hash chain. However, it only use the sequential values of Hash chain to authenticate ${\mu}TESLA$ parameters. So, It can't ensure the success of authentication in lossy sensor network. This paper is to propose the improved method for Tree-based ${\mu}TESLA$ by using XOR-based chain. The proposed scheme provide advantages such as a fixed computation cost with ${\mu}$TPCT-based ${\mu}TESLA$ and a message loss-tolerant with Tree-based ${\mu}TESLA$.
