A video summary abstracts the gist from an entire video and also enables efficient access to the desired content. In this paper, we propose a novel method for summarizing news video based on multimodal analysis of the content. The proposed method exploits the closed caption data to locate semantically meaningful highlights in a news video and speech signals in an audio stream to align the closed caption data with the video in a time-line. Then, the detected highlights are described using MPEG-7 Summarization Description Scheme, which allows efficient browsing of the content through such functionalities as multi-level abstracts and navigation guidance. Multimodal search and retrieval are also within the proposed framework. By indexing synchronized closed caption data, the video clips are searchable by inputting a text query. Intensive experiments with prototypical systems are presented to demonstrate the validity and reliability of the proposed method in real applications.

This study was aimed to study the effect of Zn content on the hyperfine parameters and the structural variation of $Ni_{1-x}Zn_xFe_2O_4$ for x = 0, 0.2, 0.4, 0.6, and 0.8. To achieve this, a sol-gel route was used for the preparation of samples and the obtained ferrites were investigated by X-ray diffraction, scanning electron microscopy, and $M{\ddot{o}}ssbauer$ spectroscopy. The formation of spinel phase without any impurity peak was identified by X-ray diffraction of all the samples. Moreover, the estimated crystallite size by X-ray line broadening indicates a decrease with increasing Zn content. This result was in agreement with the scanning electron microscopy result, indicating the reduction in grain growth with further zinc substitution. The room-temperature $M{\ddot{o}}ssbauer$ spectra show that the hyperfine fields at both the A and B sites decreased with increasing Zn content; however, the rate of reduction is not the same for different sites. Moreover, the best fit parameter showed that the quadrupole splitting values of B site increased from the pure nickel ferrite to the sample with x = 0.8.

This study was carried out to investigate the effects of diverse dietary Ca levels and to determine whether bone mineral metabolism is influenced by the arnount of dietary Ca when given a choice of diets containing various levels of Ca. Forty Hy-line brown laying hens housed in separate cages were fed self-selected Ca diets. Birds were allowed a 7-day adaptation period followed by an 8-day collection period. Feed and water were available for ad libitum consumption. Eggs and excreta were collected at 6-h intervals during the day for mineral analysis. The Ca contents in excreta and retained Ca in the body on egg forming day were proportional to the amount of daily Ca intake. The retained Ca in the body were 0.97 g in control and 1.24~1.74 g in self-selected groups, respectively. Daily Ca contents (%) in tibial cortex were not consistent with feeding time intervals. The Ca content in tibial medulla in control group was lower than those of self-selected feeding groups(P<.05). The medullary Ca content in all treatment groups increased from 10:00 to 16:00 in a day. Ca content in plasma was low between 10:00 and 16:00 and was high between 22:00 and 04:00 in the following day.

A statistical analysis of 9,771 non-glutinous rice in breeding line germplasm collected from Korea (2,836), China (2,136), Japan (1,219), and the Philippines (1,213) was conducted using normal distribution, variability index value (VIV), analysis of variation (ANOVA) and Ducan's multiple range test (DMRT) based on the data obtained from NIRS analysis. According to the normal distribution, the average protein content was 7.9%, and non-glutinous rice ranging over 10% amylose had 23.6% average content. Most resources were between 5.3 and 10.5% in protein content, and 15.7 and 31.5% in amylose content. The VIV was 0.54 for protein, and 0.83 for amylose. The average amylose content was 25.18%, 24.54%, 22.08%, and 21.47% in Filipino, Chinese, Korean, and Japanese resources, respectively, wheereas the average protein content was found to be 8.19%, 7.79%, 7.58%, and 7.42% in Filipino, Chinese, Korean, and Japanese resources, respectively. The ANOVA of amylose and protein content showed significant differences at the level of 0.01. The F-test value was 412.2 for amylose content, and 108.4 for protein when compared with the critical value of 3.78. The DMRT of amylose and protein content showed significant differences (p<0.01) among resources from different countries. The Filipino resources had the highest level of amylose and protein content, whereas; the lowest level of amylose and protein content were found in Japanese when compared with resources of other origins. These results are recommended as helpful materials in the field of breeding.

As the logistic environment of digital contents is rapidly changing, the protection of the digital rights for digital content has been recognized as one of critical Issues. Digital Right Management(DRM) has taken much interest Internet Service Provider(ISP), authors and publishers of digital content as an interested approach to create a trusted environment for access and use of digital resources. This paper propose an interested digital rights protection scheme using license agent to address problems facing contemporary DRM approached : static digital rights management, and limited application to on-line environment. We introduce a dynamic mission control technology to realize dynamic digital rights management. And we incorporate license agent to on- and off-line monitoring and tracking. The proposed system prevent illegal access and use by using PKI security method, real time action monitoring for user, data security for itself.

This study examines the design characteristics of figure skating costumes by a content analysis of their design elements. The content analysis method for the study was used based on 185 photos of female figure skaters. A total of 218 coding units in 15 categories were used. In the category of color, unicolor costumes were the mainstay and represented 48.11% of the total costumes. Black costumes showed the highest rate (13.51%), followed by red (7.57%) and blue (7.03%). In the dual-color costumes, combinations of red and black and white and black, represented 4.32% of all costumes. A camisole was the most popular type of neckline (20.54%). Stand collars with neck decorations were found in 5.95% of the costumes. In addition, 98.2% of all figure skating costumes had decorations (crystal beads 21.86% were the most frequently used decoration type), 65.41% exposed all the shoulders and arms, 70.81% of the costumes did not have sleeves, 5.41% of the costumes had arm decorations, and 3.78% had wrist decorations. In the analysis of the hem of skirts, 32.40% had a curved line, 30.73% had a straight line, and 15.08% had an unrecognizable form. In general, the figure skating costumes have stand collars with neck decorations, arm and wrist decorations, and irregular skirt hems that are not found in everyday dresses. To emphasize and intensify a theatrical effect, the costumes were fabulously decorated with spangles, crystal beads, feathers, and lace; black, red, and blue were frequently used. The skirts had frills, fringe, flared lines, and beads on them to reflect the stage lights and emphasize movements.

Are the benefits derived from ICT based reference and information service worth the financial and other commitments devoted to it? In an attempt to answer this, this study delved into finding out the perceived benefits; the rational for ICT based reference services in Nigerian university libraries. The main objectives were to find out the purposes for using ICT facilities in reference services delivery and the perceived benefits derived from using ICT resources in reference and information services. Being a survey, questionnaire was used to collect data from the librarians of twelve (12) universities; two (2) each sampled from the six geopolitical zones of Nigeria. Data was analyzed using frequencies, mean scores and standard deviations. ANOVA statistical analysis was used to test the hypothesis of no significance difference in the benefits derived from ICT based reference services using p-value of 0.05 to calculate the level of significance. Findings showed that librarians and library users made use of ICT facilities for different reference purposes especially to obtain information they need using the internet. Other reference needs for which patrons used the ICT facilities included: - access to current e-books and e - journals, user education and access to global information in other libraries. Provision of current awareness services (CAS) and selective dissemination of information services (SDI), on-line searching using workstations in the library, provision of on-line public access catalogue (OPAC) services, keeping statistics of users of the reference section and compilation of bibliographies. Further findings showed that the librarians and library users derive a lot of benefits from their use of ICT facilities in reference services. The results showed that easy retrieval and dissemination of information to patrons were ranked highest by the librarians amongst others.

Lignin modification has been a breeding target for the improvements of forage digestibility and fermentation in whole crop silage(WCS) rice. In rice, gold hull and internode 2 (gh2) was identified as a lignin-deficient mutant. gh2 exhibits a reddish-brown pigmentation in the hull and the internode is located on the short arm of chromosome 2 and codes for cinnamyl-alcohol dehydrogenase (CAD). To develop WCS rice variety improved digestibility and fermentation, we measured acid detergent fiber (ADF), lignin and total digestible nutrient (TDN) calculated from ADF (TDN=88.9-(0.79% × ADF) and performed marker-assisted selection using CAD(Os2g0187800) gene first intron region specific marker with 55 Jungmo1038/J.collection lines. Those lines had lignin content range from 0.82 to 6.61%, ADF from 15.8 to 45.8%, TDN from 52.7 to 78.8 compared to 'Jungmo1038'(1.53,20.7,72.6), 'J.collection'(0.98,12.8,78.8%) and gh2 were introgressed into 44 lines. Considering on these genotype and low-lignin phenotype, we finally selected 2 elite lines(Suweon668, Suweon669). Suweon668 and Suweon669 line are high biomass-low lignin lines that the ADF content is relatively low, even though the dry matter weight is high. Also they have lodging and shattering resistance and glabrous leaf and hull important to improve cattle palatability. Our results will provide that rice can be improved for forage digestibility and fermentation with low lignin concentration.

Korean government has taken positive policies, including making "An Basic Plan on the Conservation and Activation of the Royal Tombs of the Joseon Dynasty, UNESCO World Heritage", since 40 royal tombs of the Joseon Dynasty were inscribed as UNESCO World Heritage in 2009. However, projects utilizing the royal tombs of the Joseon Dynasty are in the beginning step and very few has been researched on those projects academically. This study analyzed total 311 projects utilizing the royal tombs of the Joseon Dynasty, which have been made by the Cultural Heritage Administration of Korea from 2009 to 2014, through the literature review and content analysis methodology. An analysis frame consists of educational, touristic, compound and industrial activation on the basis of the utilization types made by the Cultural Heritage Administration of Korea. Most projects utilizing the royal tombs of the Joseon Dynasty are in the very beginning step in terms of educational and touristic utilization. No project utilizing the royal tombs of the Joseon Dynasty in terms of industrial utilization is found. Those projects are almost similar without distinctive characteristics peculiar to each royal tombs. Most projects have been taken on the short term level and the budget size for those is not enough. Projects are mostly focused on the on-site of royal tombs with little paying attention to converging projects utilizing digital and on line techniques. Some suggestions are the followings: increase of the budget on projects utilizing the royal tombs of the Joseon Dynasty, development of content peculiar to each tomb, development of industrial projects, development of converging projects utilizing digital and on line techniques, establishment of new medium and long term plans for utilization of the royal tombs of the Joseon Dynasty and so on.
