Variable contents are extracted and used to improve the correctness of the retrieval in the content-based in age retrieval. This way use the physical feature for the retrieval. In this way of retrieval, the user has to know the basic physical features and spatial relationship of target images that he wants to retrieve. There are some restriction to reflect the user's intend. We need the retrieval system that reflect the user's intend. In this paper, we propose an emotion-based retrieval system. It is different from past emotion based image retrieval in point of view that it uses relevance feedback to estimate the users intend and it is easily combined with past content-based image retrieval system. The features and similarity measures are adopted from MPEG-7 color descriptors which are proper retrieval of large multimedia databases. We use wallpaper images for the experiment. The result shows that the system get successful result.

Soo-Yeoun Kim & Ji-Eun Kim 2016. A Study on ESP Skating English Education Based on Job Analysis. This study aims to provide skating ESP(English for Specific Purposes) education model for skating instructors in Korea. For this purpose, a total of twenty-seven professional skating instructors were surveyed according to a questionnaire, which asked about their English skills and perspective of the importance of English study and English skating class. The main results are as follows: most skating instructors' confidence in their English is low; majority of them answered that English study is needed for skating instructors; a majority of them want English teaching that focused on speaking and teaching activities. After that, skating instructors' jobs were analyzed using the DACUM(Developing A Curriculum Method). A DACUM committee extracted the duties and tasks which require English education and conducted a survey that targeted skating instructors. When interpreting the study on ESP Skating English Education based on job analysis, it was evident that the English language would be essential for enabling effective communication with judges during national sports competitions, information exchange with foreign skaters, and for technical skating instructions.

The purpose of this was to analyze the effects of the knowledge management(human capital and structural assets) on organizational performance in nursing homes. The survey was conducted 299 workers in nursing homes in Chungcheongnam and Chungcheongbuk provinces. The collected data were analyzed by frequency analysis, descriptive statistics, reliability, correlation, and regression analysis using SPSS 21.0 program. The results showed that structural assets(shared culture and process) were most significantly influential factors on organizational performance and the effects of age, position, operating entities were significant. But the impact of human capital was not significant. From the above results, the cooperation between organizations is needed to actively share knowledge in order to increase the shared culture. In addition, the institutions should try to develop a variety of programs and to provide an environment where the members talk freely in order to increase the process level.

This study aims to explore how journalistic norms are practiced in journalists tweets by analyzing journalists' twitter. The study found that journalists consider using twitter as an extension of journalistic practice rather than a private space. In other words, journalists use twitter without a clear distinction about the nature of the twitter. In terms of journalistic norms, journalists expressed actively their opinion rather than keeping the traditional notion of objectivity. There are not much tendency of sharing the gatekeeping role. Also, journalistic use of twitter does not increase transparency as much as expected. However, there is a positive sign of practicing the newly expected journalistic role, conversation with news users. Finally the relationships between journalistic use of twitter and journalistic norms are not straightforward but diverse depending on the size and type of press, and gender of journalists.

This study reports the result of the survey on collection management from 154 school libraries in Korea. The questionnaire is consisted of three section: state of collection, state of book use, and collection management system. Results reveal that (1) elementary schools and middle schools have many books for each student compared to the KLA's School Library Standards; (2) the component ratio of literature books is the biggest in school library collections; (3) the ratio of library book use is overwhelmingly higher in elementary schools than middle schools and high schools; (4) 64.6 percent of library books in the sample are never used during 2013-2015; (5) 74 percent of libraries have its own collection management document; (6) Almost all schools compose its own committee for library management, the committee plays an important roles in the communication among school members, collection development and promotion.

In a VOD system, it is desirable to provide the user with interactive VCR functions such as fast-forward and fast-backward. Typically, these functions can be implemented using the segment interleaving technique in disk away based VOD servers. But the segment interleaving nay not ensure QoS of users because of the concentrated load within some disks. In this paper, we propose an efficient load balancing technique for evenly distributing the retrieval requests across the disks. The proposed technique maintains an access counter in each disk, which has the number of disk accesses. The fast-forward/backward can be achieved by choosing a segment to be accessed from the disk with the minimum number among the access counters. We conduct simulation experiments and then show that our proposed technique outperforms the previous ones.

In this research, we are looking for new ways to parents' participation in the school education through the educational information. The qualitative research about this research is not at all state. We use the method of study based on the grounded theory. The case analysis object is a outstanding school of the educational information in 2007, ten excellent schools of the cyber home service, two research schools 2 and two schools of research for NEIS. The parents make the learning check on situation of the students and communicate with school through the cyber home learning service and NIES. Also, It is bringing parents around the school closer through the SMS service and is communication path out of time and space. We make the things that make communications work through it. We know it is building trust with the parent and school.

This paper aims at presenting high quality at low resolution apply by a new antialiasing method for voxelized implicit surfaces. Implicit surfaces create a unique type of 3D-modeling. Some use of implicit surfaces are scientific and medical visualization, animation, medical simulation and interactive modeling. One of previous antialiasing methods for implicit surfaces presented by raytracing or texture mapping is making use of a stochastic sampling. But this method requires more calculation time and costs which is caused by complicated and difficult implicit functions. In the meanwhile, voxelized implicit surfaces generally use high resolution for good quality images but it costs to generate. In order to this problem, this paper suggests a shifted double Z-buffer which is very simple, more efficient and easy. Tn addition, there are applied box-filter and tent-filter to the double Z-buffer antialiasing method for better images. For results this method generate high quality image and it is easy to apply to various filters and is able to extend to multi Z-buffer.

Until now, many Computer Aided Education(CAE) contents are developed for kids and children with disabilities The contents cover various types of training, including visual perception training, intelligence development training, and literature education areas. Major problems on those contents are those contents requires long training time on desktop machine, which deteriorates human activities. These problems also cause inaction syndrome for young kids and children with disabilities. Solving this problem, we require a human motion sensing contents on touch screen or touch board, which interacts with a trainees and enhancing activity, collaboration and immersiveness. We implement and develope an education contents interacts with a trainee using beam projector or screen and IR(Infra-Red) pens using wiimote controller sensing technology.
