  • Recently, it is increasing the interest in previous web and web 2.0 which mean differentiation. The previous system is typical Static web based on client and server model, while web 2.0 mean next generation web which web change and evolve fundamentally. In this paper, I suggest that the module on RSS reader available under web 2.0 standards. A currently used RSS feed do correct the part distortion which ran be possible resolve the encoding problem of Hanguel and third-world language. The suggested module is implemented using Ajax. I developed the module for the use of effective contents on web 2.0 through the DragBox module based on the programming on mobility of Ajax and the design and implementation of automatic update module of RSS feed.

  • Labeling schemes which don't consider about frequent update in dynamic XML documents need relabeling process to reflect the changed label information whenever the tree of XML document is update. There is disadvantage of considerable expenses in the dynamic XML document which can occurs frequent update. To solve this problem, we suggest prime number labeling scheme that doesn't need relabeling process. However the prime number labeling scheme does not consider that it needs to update the sibling order of nodes in the XML tree of document. This update process needs much costs because the most of the XML tree of document has to be relabeling and recalculation. In this paper, we propose the prime number labeling scheme with sibling order value that can maintain the sibling order without relabeling or recalculation the XML tree of documents.

  • In this paper, we propose a technique for processing of speech recognition in korean words. Speech recognition is a technology that converts acoustic signals from sensors such as microphones into words or sentences. Most foreign languages have less difficulty in speech recognition. On the other hand, korean consists of vowels and bottom consonants, so it is inappropriate to use the letters obtained from the voice synthesis system. That improving the conventional structure speech recognition can the correct words recognition. In order to solve this problem, a new algorithm was added to the existing speech recognition structure to increase the speech recognition rate. Perform the preprocessing process of the word and then token the results. After combining the result processed in the Levenshtein distance algorithm and the hashing algorithm, the normalized words is output through the consonant comparison algorithm. The final result word is compared with the standardized table and output if it exists, registered in the table dose not exists. The experimental environment was developed by using a smartphone application. The proposed structure shows that the recognition rate is improved by 2% in standard language and 7% in dialect.

  • We are facing an era of automation where artificial intelligence works and an era of super-aging, where birth is rapidly declining. In this paper, we intend to perform the creation of an autobiography in conjunction with the generation integrated narrative storytelling, thereby exploring the potential for visual storytelling that can be extended to a variety of media format. The visual autobiography production program confirmed through an interview with the production participants that grandparents, grandchildren and granddaughter together became the main characters in the documentary, a valuable opportunity to reflect on their past memories and lives and recognize their meaning of life. The visual storytelling education program model and media life service presented in this paper will be shared by the youth and the elderly generation together and contribute to the 'sympathetic culture' as a social integration program.

  • This study investigated the possible use of enzymatically hydrolyzed isolated soy protein (eHISP) to enhance the intensity of salty taste. The sodium chloride content of eHISP is 69.5 g/L. Yellowness (b) increased, and lightness (L) and redness (a) decreased with increasing eHISP concentration in sample solution. Also, perceived salty intensity of eHISP solution increased in sample solution with increasing added amount of eHISP with same NaCl concentration. The intensity of the salty taste was enhanced by 2-39% as the eHISP was added. The results suggest that it may be possible to reduce the content of sodium chloride in foods by enhancing the salty taste with eHISP.

  • Busan Port ranked 6th in the world with 21.67 million TEUs of container handling in 2018, but the ship supply industry has fallen short of that. Despite its technological prowess, Korea's ship supply industry lacks competitive edge in many aspects such as government support, integrated platform, and infrastructure compared to overseas ship supply industries. The use of code, which is not standardized, can be cited as a leading factor that undermines the competitiveness of Korea's ship supply industries. In the ship supply industry, the use of non-standardized codes can make it difficult to manage or analyze meaningful statistics, and, by extension, can lead to the loss of new business opportunities. Therefore, in this study, we intend to use local ship supply transaction data to study how to standardize item code to solve the problem.

  • The importance and necessity of convergence research to solve complexity and diversity of research problems is more increasing. For successful convergence research, connectivity beyond the boundary and distance between disciplines is a key factor. To understand the current status and characteristics of connectivity among researchers, we investigated the interdisciplinary relationships among 487 researchers' disciplines in a university by using network anaylsis. The results showed that (1) connectivity between similar disciplines were higher than different disciplines, (2) the density and cohesion level of connectivity within the same campuses were higher, and (3) network centrality was concentrated in engineering and medicine. Based on these results, the necessity of overcoming boundaries and distances as obstacles to convergence research and the necessity of diversification of centrality were proposed. While previous studies mainly analyzed the research outcomes, this study is meaningful because it analyzed researchers' connectivity and collaborative structures in the actual convergence research procedures.

  • In ISO MPEG, MPEG-H has been standardized to smoothly deliver huge volume of ultra-high resolution videos over heterogeneous network environments for the consumers. In the MPEG-H standard, MMT(MPEG Media Transport) protocol is the next generation MPEG media transport technology to provide hybrid media delivery over heterogeneous environments. It is important to sustain accurate media synchronization to provide ultra-high resolution video services over heterogeneous network environments. In this paper, we propose and verify an in-band media synchronization scheme to circumvent the problem of additional session setup and excessive traffic problems of the conventional out-of-band media synchronization supported by the MMT technology.

  • With the development of information and communication technology and the increasing use of smart devices, universities are using an electronic attendance-absence management system using smart devices to facilitate efficient attendance management. Currently, the electronic attendance-absence management system has the disadvantage of causing an error in attendance when the Wi-Fi connection is not well established because the student's smartphone independently conducts electronic attendance, and it is difficult to manage attendance because the real-time push message transmission function is excluded. In this paper, we propose an electronic attendance-absence management system to prevent irregular attendance, provide real-time attendance results, and solve delays in attendance processing due to Wi-Fi connection problems. The proposed system can prevent delays in attendance processing as a result of irregular attendance because the instructor's smartphone processes proposed system using the Bluetooth communication function of the instructor's smartphone and the students' smartphone. In addition, it has the advantage of being able to notice management result in real time with the push message server.

  • Due to the development of deep learning and AI, the scale of the model has grown, and it has been integrated into other fields to blend into our lives. However, in environments with limited resources such as embedded devices, it is exist difficult to apply the model and problems such as power shortages. To solve this, lightweight methods such as clouding or offloading technologies, reducing the number of parameters in the model, or optimising calculations are proposed. In this paper, quantization of learned models is applied to ONNX models used in various framework interchange formats, neural network structure and inference performance are compared with existing models, and various module methods for quantization are analyzed. Experiments show that the size of weight parameter is compressed and the inference time is more optimized than before compared to the original model.
