The purpose of this study was to analyze characteristics of effective expression on T-shirts pattern by peirce's semiotic theory. The methods of this study was to analyze 721 T-shirts patterns in designer's collection from 2000 to 2004. The results of this study were as follows: First of all, iconic expression showed high frequency after 2000. Characteristics of effective expression were as follows: In geometric expression, repetition was presented as a symbolic sign by regular proportion and rule of dot, line, plane, irregularity, mixture of irregular dot, line, plane. Mixed expression was presented as a iconic and symbolic sign by collage, mixture of dot, line, plane, icon and letter. In iconic expression, simplification of iconic sigrl was presented as a iconic sign by simplification of form, color, texture, realistic expression using digital as a iconic sign, and symbolic face, body as a symbolic sign. Pop art's expression was presented as a iconic sign by a cartoon and commercial character and illusion was presented as a iconic sign. In letter's expression, brand logo was presented as a symbolic sign by transformation of letter's design, a symbolic sign of numeral by transformation of size, thickness, form, color. Symbolic message phrase was presented by slogan, fashion trend, brand image, descriptive indication message as a index sign by using icon or singleness. In conclusion, characteristics of effective expression on T-shirts pattern will present not only the theoretical foundation to raise the value added, but also the information about beauty sense of times, political and social value.

An advanced vehicle safety system can be constructed by exchanging danger-related information ,such as urgency stop, traffic accident, obstacle, and car trouble, among the vehicles. However, because network topology changes rapidly and frequently due to the mobility of vehicles, it is impossible to configure the network for information forwarding in this environment. In the most of vehicle safety communication applications, an emergency message is propagated in a form of broadcasting. The simple broadcasting causes a lot of problems in terms of efficiency due to multi-hop area and radio collision problem. This paper proposes a method of selective message forwarding with stem and branch structure for propagating the emergency messages. However, the proposed method raise the efficiency of message transmission with the selective forwarding based on the priority assignment as its location. We analyze and evaluate the performance by comparing the proposed scheme with other schemes that are presented in the paper.

This study investigated the effects of thae persuader and the persuasion message in order to reduce carbon dioxide emissions and activate the exploration journey using bicycles, a form of green transportation, in this green society age. Furthermore, the effects that predictive variables related to the implementation of an infrastructure for bicycles have on the intentions toward an exploration journey using bicycles were examined. The questionnaire survey was administered to 257 respondents for 9 days from March 14 to March 22, 2009. Since Gyeongju has a number of cultural relics that people can look at in one day, Gyeongju is ideal for examining a variety of tourist opinions about exploring cultural relics using bicycles. In conclusion, it was found that the 'persuader' and 'persuasion message' enhanced the desire for bicycle exploration journeys from 'will use a bicycle if possible' to 'want to use a bicycle'. In accordance with two-way ANOVA results on the desire for bicycle exploration journeys by persuader and persuasion message, the persuasion approach emphasizing health effects and geared toward bicycle enthusiasts was significantly effective. Furthermore, the most effective approach was the persuasion strategy emphasizing the 'citizens' and 'health', and 'citizens' and 'eco-friendly' among the effects created by connection of persuader and persuasion message.

This study has recently been issued to businesses and consumers who examined the effects of cross-advertising model. Experimental design, the model type (2) ${\times}$ sexuality products (2) ${\times}$ advertising message appeal form (2) is a factorial design. The results are as follows. First, the advertising model, based on the type of cognitive response to advertising than the general model of cross-recall index was higher model. Second, the product of gender identity in response to what the advertising product for women than men was higher index of product recalls. Third, the ad attention model ANOVA results for each type of message, the main effect of appeal type was identified. In addition, the type and model of sexual identity, and message appeal type in the type of model interaction effects were found. Finally, the model-product analysis of goodness of fit, the model type and sexual identity and appeal type messages of main effect were identified. The result is more efficient advertising effect model strategies for promoting meaningful results, it is meant to be confirmed.

This research analyzed the relationship and the interaction effect between information understandability and information acquisition level in accordance with government's official message presentation types, in other words, press release in text form, infographic that visualize a large amount of information, and webtoon that helps to understand convoluted information in interesting ways. As a result of research, it was confirmed that there exist both main effect and interaction effect in official message types presented by government and information understandability according to the environmental awareness. In addition, the main effect per each variable was confirmed between official message types presented by government and information understandability according to the environmental awareness; however, the interaction effect per each variable was not confirmed. Such research result is meaningful in that it provides the government with basic data in obtaining the effectiveness and usefulness of the information dependent of the official message types presented by government to the information consumer facing the era of government 3.0.

Exchange of data between users and system is made by users' inputting their information into HTML input forms like when signing up in websites or buying in online shopping malls. If users make a mistake of inputting their information, the system gives an error message in order for users to correct their mistakes. Although ISO recommends immediate feedback, Bargas et al. gave a report that feedback in all after filling forms out is more usable than feedback one by one when inputting data online. We made a comparative experiment on usability under each case of feedback one by one and feedback in all. The result is immediate feedback is more usable and satisfactory. The analysis of data resulted that immediate feedback produced fewer error and gets higher subjective ratings.

Impersonation attack, based on vulnerable security of SIP, facilitate a intruder to take malicious actions such as toll fraud and session hijacking. This paper suggests a new technique for a countermeasure. When receiving a register request message, registrar checks whether the value of Form header or the value of Call-ID header is stored in location server or not. If the record containing either of them are stored and periodically updated, we regard that message as impersonation attack and discard it. Since this technique uses the information stored in server instead of adding encryption mechanism for user authentication, it can easily build securer SIP environment.

Text analysis technique for natural language processing in deep learning represents words in vector form through word embedding. In this paper, we propose a method of constructing a document vector and classifying it into spam and normal text message, using word embedding and deep learning method. Automatic spacing applied in the preprocessing process ensures that words with similar context are adjacently represented in vector space. Additionally, the intentional word formation errors with non-alphabetic or extraordinary characters are designed to avoid being blocked by spam message filter. Two embedding algorithms, CBOW and skip grams, are used to produce the sentence vector and the performance and the accuracy of deep learning based spam filter model are measured by comparing to those of SVM Light.

The purpose of this study is to examine the legal aspects on the formation of international contract in electronic commerce. The findings could be summarized as follows. rug, the contract doctrine of the contract formation by electronic data message, time of dispatch and receipt of data message, error in electronic communication, contract form and electronic signature could be supported or protected by the existing contract doctrine. Second, In relation to the contract formation arranged by electronic agents, the established contract doctrine provides no clear answer to the question whether changes provided by the interaction of electronic agents are enforceable. The enforceability question is left to future legislation. Finally, It is necessary that a significant level of formality together with the disclosure on the contract formality by certain act be conveyed 10 a potential buyer so that the buyer is impressed that the contact by the certain act could be valid.
