Cho, Jae-Hwan ;
Journal of Digital Contents Society, volume 11, issue 3, 2010, Pages 283~290
The effectiveness of 3.0T phase array coil images was tested by comparing signal-to-noise ratios for the same coil images relative to 1.5T endorectal coil images. Signal intensities were measured in the three regions of prostate, central and peripheral (right and left) after 40 patients with prostate cancer were imaged during the period between Jan. 2008 and Oct. 2009 with T2 W, T1 W, and DW images obtained respectively using endorectal coil on a 1.5T MR scanner and phase array coil on a 3.0T MR scanner. For quantitative analysis, comparisons of average SNRs for the same ROIs were made between groups scanned with a 1.5T and a 3.0T MR scanner. The signal-to-noise ratios were shown to increase more sharply when using a phase array coil at a 3.0T MR scanner compared to using an endorectal coil at a 1.5T MR scanner.
A TV Viewer's Modality-based Searching System Designed for Running on TV Set
Ko, Kwang-Il ;
Journal of Digital Contents Society, volume 11, issue 3, 2010, Pages 291~298
Although searching service is popularized in the PC-based internet environment, it is not (or rarely) supported on TV, which is the major multimedia equipment in the living room. Several trials are made to port established PC-based searching systems onto TV-set but failed to get popularity among viewers as they did not consider the viewers' modality. Operating the searching system should not disturb viewers in watching TV (for example, TV screen should not be (even partially) covered by the searching system's graphics) and the number of pushing the remote controller's buttons should be minimized so that viewers can keep watching TV without glancing at the searching system's graphics. In this paper, the author introduces a new searching system running on TV-set, which is designed to reflect properly the viewers' modality. The searching system is also compatible with the data service standard adopted by the domestic broadcasting networks so that it can be easily implemented by them.

The demand for cyber education in Korea is constantly increasing and the need for research on online lecture on contents design that increases the learning effect is rising. In this research, the online lecture contents about the technical information type provided by Korea Cyber University was understood and we researched about the most preferred lecture type and the most effective lecture type in learning among the 1,173 students in Korea Cyber University who participated in this online survey. Also, we analyzed if the students' preference for the lecture type depended on their experience on that lecture type and we studied the students' claims postulated on the interface design of the lecture contents. The most preferred lecture type among students was e-Stream+flash and they answered that multi-media type lectures were the most effective lectures in learning. The majority of the students preferred lecture contents that they have experienced before and preferred the menu on the left side of the page in interface design. Not only the completeness, but the applications in design in lecture contents are also an important factor in online lectures. As the demand for cyber education in Korea is increasing, content design that can increase the academic performance should be further researched.

Journal of Digital Contents Society, volume 11, issue 3, 2010, Pages 323~330
Due to the widespread smartphones and application stores, mobile application developments are now booming again in the same manner of PC history. The smartphone software development process, however, gives much inconvenience to developers because of the heterogeneous platform APIs and hardware incompatibility between different devices. To make clear these problems, mobile web applications are being accepted as an alternative to the native smartphone applications. Mobile web applications can be developed more simply and easily than native applications by using webkit engine's html, Java script, and CSS. Additionally developers can provide a platform-independent applications since web applications are going to run on web browsers. In this paper, we develop a personal applications store running on an android phone's browsers. We can accomplish this very simply by using webkit's various APIs such as OpenID. We can find out by implementing a real web application that development of web applications can surpass the native one in cost and time period without much loss of performance.

Kong, Ki-Sik ;
Journal of Digital Contents Society, volume 11, issue 3, 2010, Pages 341~348
Unlike host-based IPv6 mobility support protocols such as Mobile IPv6 (MIPv6), Hierarchical Mobile IPv6 (HMIPv6), and Fast handover for Mobile IPv6 (FMIPv6), Proxy Mobile IPv6 (PMIPv6) is expected to accelerate the real deployment of IPv6 mobility support protocol by using only collaborative operations between the network entities without mobile node (MN) being involved. In this paper, we analyze and compare the handover latency of network-based IPv6 mobility support protocol (i.e., PMIPv6) with the representative host-based IPv6 mobility support protocols such as MIPv6, HMIPv6, and FMIPv6. Analytical results show that the handover latency of PMIPv6 is considerably lower than those of MIPv6 and HMIPv6, and the handover latency of PMIPv6 becomes lower than that of FMIPv6 in case the wireless link delay is greater than the delay between mobile access gateway (MAG) and local mobility anchor (LMA).

Personalized web search engine provides personalized results to users by query expansion, re-ranking or other methods representing user's intention. The personalized result page includes URL, page title and small text fragment of each web document. which is known as snippet. The snippet is the summary of the document which includes the keywords issued by either user or search engine itself. Users can verify the relevancy of the whole document using only the snippet, easily. The document summary (snippet) is an important information which makes users determine whether or not to click the link to the whole document. Hence, if a search engine generates personalized document summaries, it can provide a more satisfactory search results to users. In this paper, we propose a personalized document summary system for personalized web search engines. The proposed system provides increased degree of satisfaction to users with marginal overhead.

Journal of Digital Contents Society, volume 11, issue 3, 2010, Pages 375~383
In developing question-answering (QA) systems, it is hard to analyze natural language questions syntactically and semantically and to find exact answers to given query questions. In order to avoid these difficulties, we propose a new style of question-answering system that automatically generate natural language queries and can allow to search queries fit for given keywords. The key idea behind generating natural queries is that after significant sentences within text documents are applied to the named entity recognition technique, we can generate a natural query (interrogative sentence) for each named entity (such as person, location, and time). The natural query is divided into two types: simple type and sentence structure type. With the large database of question-answer pairs, the system can easily obtain natural queries and their corresponding answers for given keywords. The most important issue is how to generate meaningful queries which can present unambiguous answers. To this end, we propose two principles to decide which declarative sentences can be the sources of natural queries and a pattern-based method for generating meaningful queries from the selected sentences.

Journal of Digital Contents Society, volume 11, issue 3, 2010, Pages 393~398
Composite and compact devices equipped with the functionality of digital still image acquisition, such as cellular phones and MP3 players are widely available to common users. In addition, the application of digital still images is becoming common among security and digital recording devices. The amount of still images, that are maintained or shared in personal storage or massive storage provided by various web services, are rapidly increasing. These still images are bound with file names or identifiers that are provided arbitrarily by users or that are generated from device specific naming method. However, those identifiers are vulnerable for unexpected changing or eliminating so that it becomes a problem in still image search or management. In this paper, we propose a method for still image identifier generation that is created from the still image internal information.
