Purpose - The purpose of this study is to investigate the effect of brand message type on the object relevance between consumers and brands and to identify the mediation role of the object relevance in the effect of the message type on brand attitude. Research design, data, and methodology - Types of pride are classified into hubristic pride and authentic pride, and brand message types are divided into ability message and warmth message. Restaurant brand was selected by empirical study, and the experiment was performed with 2 (pride type: hubristic versus authentic) × 2 (message type: ability message versus warmth message) between-subjects design. The subjects of the experiment consisted of the undergraduates taking courses related to marketing. A preliminary step was taken to explore the difference in the perceived level of object relevance induced from each type of message between the consumer group that felt hubristic pride and the other group that felt authentic pride. This study analyzed the mediating role of the object relevance in the effects of the message type on brand attitude by means of Bootstrap method for each of the pride groups. Results - The results from the empirical analysis are summed up as follows. Regardless of pride types they felt in advance, consumers perceived their object relevance to be higher in the warmth information message than in the ability information message, and object relevance was analyzed to have a positive effect on brand attitude. It was analyzed that, regardless of pride types, object relevance played full mediation roles in the effect of warmth information versus ability information message on brand attitude. Conclusions - Based on the results, it may be suggested that marketers of a brand should endeavor to develop a warmth information message rather than a ability information message to prompt consumers to perceive the object relevance between their own brands and consumers, regardless of pride types, as long as a consumer feels pride in advance. In order to increase the consumers' attitude toward their brand, the brand marketers are solicited to check the object relevance between their brand and consumers, then, seek for the managerial ways to promote such object relevance.

Purpose - Previous studies on the influence of appeal types of advertising messages on pro-social behavior have shown inconsistent results. The purpose of this study is to examine whether the appeal type of advertising affects consumer's prosocial behavior. In particular, the authors investigated whether the social exclusion moderates the relationship between the appeal type of advertising and prosocial behavior. Research design, data and Methodology - To verify the hypothesis, two experimental study were conducted. The experimental study was 2(appeal type : self-benefit vs. other-benefit) by 2(social exclusion : being ignored vs. being rejected) between-subject design. Participants were randomly assigned to one of four conditions. The experiment was conducted using a computer. First, the participants was exposed to the advertising image used in the social campaign, and then responded to questions about social behavior. The participants completed the experiment after further responding to the item for manipulation check and demographic measure. The experiment took about 10 minutes in total. Results - In Study 1, a global warming campaign with participation intention variable, other-benefit ads rather than self-benefit ads drive consumers who feel socially rejected to be more willing and likely to participate, but consumers who feel socially ignored are more likely to participate the campaign in self-benefit ad than other-benefit ad. Study 2 replicates the findings, a child poverty relief campaign with an amount-to-donate variable: consumers who feel explicitly rejected allocate more dollars to the charity in response to other-benefit rather than self-benefit ads, but consumers who being ignored are willing to donate more money. Conclusion - This study has theoretical contribution in that it expands existing theories by explaining the existing inconsistent results of the message appeal influence on pro-social behavior through new control variables. In addition, the results have important managerial implications, suggesting marketers should tailor their marketing message to match the consumer situation.

Recently, SIP(Session Initiation Protocol) is used to set up and manage sessions for multimedia applications such as VoIP(Voice over IP) and IMS(IP Multimedia Subsystem). However, because SIP operates over the Internet, it is exposed to pre-existed internet security threats such as service degradation or service disruptions. Multimedia applications which are delay sensitive even suffers more from the threats mentioned above. The proposed methods so far to detect SIP INVITE flooding are CUSUM(Cumulative Sum), Hellinger distance and adaptive threshold, but among methods only take normal state into consideration. So, it is not capable of adapting the condition of the network congestion which are dynamically changing. In this paper, SIP INVITE flooding detection algorithm considering network congestion which enables efficient detections of such attacks is proposed. The proposed algorithm is expected to detect other types of attacks such as BYE and CANCEL more precisely compared to other methods.

Developed safety system which transfers danger information to rear cars for accident prevention when drivers detect a accident, a dropping or a freezing during driving on the high way. To prevent an accident, each vehicles mount OBU which is made up of a GPS unit and a transmitter-receiver and the trace of road is always renewed and saved in OBU per a regular past distance. When the driver see dangerous situation, transfer a danger pattern and a trace information by pressing button. All cars which receive information compare the received data with the original data. And then, only cars which are located at the rear in a regular distance respond and occur a warning. Performed a road test at the rate of $30{\sim}50$ kilometer a hour using two test cars which saved about 120meter's space between them were mounted OBU which had 447Mhz transceiver. As a result of the experiment, communication between test cars had no problem. Accordingly, it can use a safety driving device because driver can notice a danger situation and set themselves ready for it using this system in advance.

Following is discovered in this study by some. First, attribute(product/non- product) of that truth that get through experiment of this study is WOM deduced result that have statistical meaning in dependent variable which is public trust only in this study. Specially, information by word of mouth type received High positive response more with non-product information by word of mouth attribute than the product attribute in all experiment products that is parted according to involvement. Consumer's response by involvement level of product can affect for site attitude, public trust, and intention to purchase by second. For example, consumer's site attitude has induced the most positive response, and can confirm positive response of High consumer most in that involvement sensitivity product in that participation reason type product and could confirm response that is the most positive in that involvement reason product even if there is for intention to purchase. Result of this study is grasped that have High mean value relatively in site attitude, product attitude, information by word of mouth effect, public trust, brand attitude, purchase intention etc. generally that product involvement and information by word of mouth attribute are interrelation by third. This can change fairly data processing process according to consumer's Involvement Level, behavior deterministic process, consumer's action with attitude formation process, and involvement for products. High occasion than is low incline more efforts in information retrieval and is discreet result such as study finding of produce.

Most threats of WLAN are easily caused by attackers who access to the radio link between STA and AP, which involves some Problems to intercept network communications or inject additional messages into them. In comparison with wired LAN, severity of wireless LAN against threats is bigger than the other networks. To make up for the vulnerability of wireless LAN, it needs to use the Intrusion Detection System using a powerful intrusion detection method as SVM. However, due to classification based on calculating values after having expressed input data in vector space by SVM, continuous data type can not be used as any input data. In this paper, therefore, we design the IDS system for WLAN by tuning with SVM and data-mining mechanism to defend the vulnerability on certain WLAN and then we demonstrate the superiority of our method.

Smartphone has become a part of many people's daily lives. The mobile messenger function on the smartphone in particular is the most frequently used services. The mobile communication tool in the age of digital media can be classified into two big categories: text messages and emoticons, the non-verbal expression tool of one's emotions. This thesis has studied the mobile communications made by the non-verbal tool of emoticons. The history of emoticons traces back to the text-based emoticon created by Scott Fahlman, from which graphical emoticons were developed and the sound and animation effects have been added. Many people use emoticons and diverse companies are developing the tool. In this study, the representative emoticon development case of Line Co., Ltd. is analyzed to see the concept, types, development process, collaborations and merchandising of the emoticons. Based on the case of Line, the development orientation and direction of domestic emoticons will be discussed to be culture contents.

본 연구에서는 웹기반의 화물차량위치추적시스템의 개발과 관련된 문제를 다루고 있다. 화물위치추적 시스템이란 이동하는 화물차량으로부터 위치데이터 및 관련 정보를 수신하여 중앙관제센터에서 이 정보를 데이터베이스에 저장하여 두고 화물위치 정보를 지도 위에 표시하는 시스템으로 화주, 운송회사 등 육상물류관련 기관에서 화물위치추적, 공동수배송, 화물차량 통제 등 다양한 목적으로 사용될 수 있다. 화물차량위치추적시스템은 AVLS(Automatic Vehicle Location System)라 불리우면서 산업계에서 활용되고 있으며 위치획득 방법의 종류에 따라 다양한 유형의 AVLS모델이 등장하고 있다. 예를 들면 전통적인 GPS(Global Positioning System) 위성 수신, DGPS(Differential GPS) 기지국, PCS(Personal Communication System) Cell, 도로기반 시설에 포함되는 비콘 등의 방법에 의해 AVLS는 구현되고 있다. AVLS는 정보통신 요소 기술과 정보통신 기반 시설로 구성되는데, 정보통신 요소기술로는 위치획측의 매개체인 AVL단말기와 관제시스템 S/W. 그리고 GIS(Geographic Information System)가 있고, 정보통신 기반 시설로는 차량의 단말기와 관제시스템 사이의 데이터 중계를 담당하는 네트워크가 있다. 화물차량위치추적시스템을 구성하기 위한 구비요건으로 중계망의 안정성과 신뢰성, 획득한 위치데이터의 정확성, 관제시스템의 완성도와 AVL단말기의 사용자 인터페이스, GIS S/W개발을 위한 Map API(Application Program Interface)등을 들 수 있다. 본 연구에서는 PCS Cell 방식에 의한 위치결정방식을 채택하였는데, 이것은 PCS망을 기반으로 데이터를 주고받이며 인터넷 단말기로 확장 가능한 PCS 단말기를 사용해서 위치추적을 하는 시스템이다. 이러한 시스템을 선정하게된 배경은 단말기아 망 이용료의 가격이 저렴하여 현실적으로 트럭이 쉽게 부착할 수 있다는 장점이 있으며 나아가 인터넷 단말기를 활용하여 차량과 관제센터사이에 메시지 전송 등 부가적인 서비스가 가능하기 때문이다.
