Recently, there are many communication softwares based on text on various smart devices. Unlike traditional print publishing, mobile publishing and SNS tools tends to utilize more decorative or more emotional fonts so that users can pass some feelings from contents. So font providers have released new fonts which deal with the requirements of the market. Nevertheless being released lots of new fonts, general users have not used them because they searched only by font name or font provider's name. It means that there is no way for users to know and find new things. In this study, we suggest font shape classification rules for font registration system based on font design features. We proved the validity of classification standard study through some experiments with 50 commercial fonts. Also the result of this study was provided for Korea Telecommunication Technology Association and adopted by the Korea industrial standard.

With lots of portable convergence mobile device coming out into the market, companies are now facing to take up consumers' needs. The products are popularized by 'skin function' in the field of hardware, whereas software wise, it's still a long way to follow up the needs. It's been hypothetically known that the Image of Sensitivity Adjective chosen by the users can increase the brand image and value creating capabilities through visualization. We collect the 'adjective' of images of recent products first and on that base, we sort out the most popular 'adjective' through grouping, then we actualize the image with that sample collective body. Then through analyses of the image, we find how they are correlated and what their elements are with the result.

Focusing on the rapid market penetration of smart phones, the importance of LBS (Location Based Service) is drastically increased. However, traditional GPS method has critical weakness caused by limited availability, such as indoor environment. WPS is newly attractive method as a widely applicable positioning method. In WPS, RSSI (Received Signal Strength Indication) data of all Wi-Fi APs (Access Point) are measured and stored into a huge database. The stored RSSI data in database make single radio fingerprint map. By the radio fingerprint map, we can estimate the actual position of target point. The essential factor of radio fingerprint database is data integrity of RSSI. Because of millions of APs in urban area, RSSI measurement data are seriously contaminated. Therefore, we present the unified filtering method for RSSI measurement data. As the results of filtering, we can show the effectiveness of suggested method in practical positioning system of mobile operator.

Recently, online commerces are becoming more common due to factors such as mobile technology development and smart device dissemination, and online review has a big influence on potential buyer's purchase decision. This study presents a set of analytical methodologies for understanding the meaning of customer reviews of products in online transaction. Using techniques currently developed in deep learning are implemented Hierarchical Attention Network for analyze meaning in online reviews. By using these techniques, we could solve time consuming pre-data analysis time problem and multiple topic problems. To this end, this study analyzes customer reviews of laptops sold in domestic online shopping malls. Our result successfully demonstrates over 90% classification accuracy. Therefore, this study classified the unstructured text data in the semantic analysis and confirmed the practical application possibility of the review analysis process.

Now internet is very popular. Many company services various contents in Web. One of the best way for internet community is network game service for internet member. There are some company to service high quality network game for gathering members. Those company make success for getting fee from their member. Global on-line game market is small but stability growing. Thus Microsoft invest on line game. On this paper, one of a java network turn game system called by "Hoola" is designed and implemented. This Application consist of Client/Server and Database module and multi-tier Architecture, because of easily translation to PDA or mobile phone.

Today, Advertisement affects the daily consumption life of consumers because of the features and advantages of advertisement. In particular, and so does the TV advertisement. Therefore, customer education is required for the consumers so that they can lead a rational consumption through TV advertisement quality. In addition, with the introduction of the many new-born distribution channels, the recent market environment in apparel industry is changing, and the service and image of store types consumers can choose are increasing. The purpose of this research is to offer basic data which can help consumers to acquire necessary information and conduct rational consumption through TV advertisement. Also purchasing behavior of consumers communicate, feels of consumers about store image, TV advertisement quality of what is the attitude of the relative influence presents.

Smartphone services seem to be appealing to people worldwide and show rapid growth in mobile service market. Based on the theoretical framework like attachment theory and self-congruity theory, we developed the research model and proposed six hypotheses. An analysis of 113 smartphone service users found that continued use intention in smartphone services is affected by uses' attachment to the service. We also found that the attachment is significantly increased by self-congruity, customization, and perceived usefulness. Our aim was to gain insight into ways of creating an environment that facilitating continued use intention of smartphone services. This study has important implications for academic researchers and practitioners who seek to understand why smartphone service users continuously use their smart phone services. Other practical implications of these findings and future research implications are also discussed.

In the paper, QCELP (qualcomm code excited linear predictive), CDMA (code division multiple access)'s vocoder algorithm, was analyzed. And then, a ptich parameter seaarch architecture for 16-bit programmable DSP(digital signal processor) for QCELP was designed. Because we speed up the parameter search through high speed DSP using two MACs, we can satisfy speech codec specifiction for the digital celluar. Also, we implemented in FIFO(first-in first-out) memory using register file to increase the access time of data. This DSP was designed using COMPASS, ASIC design tool, by top-down design methodology. Therefore, it is possible to cope with rapid change at mobile communication market.
