The study analyzed a diachronic distribution, social meanings and social evaluations of ROOJIN. 'Headline Database of Newspaper Articles' and 'Balanced Corpus of Contemporary Written Japanese' by KOKKEN were used as research data. There were 305 newspaper articles (About 0.2%) which contained the word ROOJIN at 'Headline Database of Newspaper Articles'. The number of newspaper articles related to ROOJIN started to increase in a rapid rate in 1972 and 1973. They were also increased in 1976, from 1981 to 1987, 1992 and 1993. The reasons of increasing of newspaper articles related to ROOJIN on those 4 periods of time could be summarized as follows. Firstly, there was a increasement of ROOJIN who are lonely, are not able to move about freely or live alone. Secondly, the understanding of a symptom of aging called BOKE was necessary. Thirdly, there were negative evaluations in a society towards ROOJIN. There were 453 cases which contained the word ROOJIN at 'Balanced Corpus of Contemporary Written Japanese' on the data since 2000. The most frequently used words were ones that are related to senior care facilities. There were 109 cases (24%) which contain those words. '~SISETSU', '~SENTA-', '~HO-MU' were presented as words related to senior care facilities. Among them, 78 cases contained the word '~HO-MU' which was similar to a home with family members. The second most frequently used words were ones that are related to 'welfare for the aged' and they are led by 'medical care for the aged'. They occupied about 8%. Institutionalization of medical care for the aged, medical expenses, nursing were presented as words related to 'medical care for the aged'. Words that were related to 'welfare for the aged' led by 'senior care facilities' and 'medical care for the aged' occupied about 32% of research data. As mentioned above, problems of the aged in Modern Japan such as negative evaluations in a society towards ROOJIN, ROOJIN who are lonely, are not able to move about freely or live alone, BOKE could be identified by analyzing the data. Also, The frequent usage of words such as 'Home for the aged', 'medical care for the aged' and 'nursing' could be identified. The outcome of analysis suggested that a family traditionally had a function of solving problems of the aged but that function was reduced in modern Japan. It also suggested that there was a tendency to outsource problems of the aged as much as possible.

Traditionally used for networking computers and communications, the Internet has been evolving from the beginning. Internet is the backbone for many things on the web including social media. The concept of social networking which started in the early 1990s has also been growing with the internet. Social Networking Sites (SNSs) sprung and stayed back to an important element of internet usage mainly due to the services or provisions they allow on the web. Twitter and Facebook have become the primary means by which most individuals keep in touch with others and carry on substantive conversations. These sites allow the posting of photos, videos and support audio and video storage on the sites which can be shared amongst users. Although an attractive option, these provisions have also culminated in issues for these sites like posting offensive material. Though not always, users of SNSs have their share in promoting hate by their words or speeches which is difficult to be curtailed after being uploaded in the media. Hence, this article outlines a process for extracting user reviews from the Twitter corpus in order to identify instances of hate speech. Through the use of MPCA (Modified Principal Component Analysis) and ECNN, we are able to identify instances of hate speech in the text (Enhanced Convolutional Neural Network). With the use of NLP, a fully autonomous system for assessing syntax and meaning can be established (NLP). There is a strong emphasis on pre-processing, feature extraction, and classification. Cleansing the text by removing extra spaces, punctuation, and stop words is what normalization is all about. In the process of extracting features, these features that have already been processed are used. During the feature extraction process, the MPCA algorithm is used. It takes a set of related features and pulls out the ones that tell us the most about the dataset we give itThe proposed categorization method is then put forth as a means of detecting instances of hate speech or abusive language. It is argued that ECNN is superior to other methods for identifying hateful content online. It can take in massive amounts of data and quickly return accurate results, especially for larger datasets. As a result, the proposed MPCA+ECNN algorithm improves not only the F-measure values, but also the accuracy, precision, and recall.

The hybrid phenomenon of pronunciation of K-Pop lyrics, which is the diction fusion phenomenon of lyrics, is not a strategic measure for an overseas expansion but a natural formation in the course of history of K-Pop. With the debut of Seo Tai-ji and Boys in 1992, the course of K-Pop changed and settled from ballad to dance music. After three years, the success of a hip hop dance music, 'Come Back Home', opened up a door to Korean Americans who ascertained the potential competitiveness of a hip hop music in K-Pop market. And the writer insists that such advance of Korean Americans into K-Pop market is the origin of the bilingual usage and diction fusion phenomenon of K-Pop lyrics. Therefore, this research will look into the pronunciation system of Korean and English in order to understand the bilingual pronunciation system shown in the lyrics sung by Korean American hip hop singers in the 1990s. Moreover, through Korean pronunciation system, this analysis will discover the main cause of continual acceptance and application of Korean American's broken Korean in the diction of lyrics. Last but not least, this exploration will show the correlation of English pronunciation method of Korean lyrics appeared in K-Pop and the diction of Korean lyrics used by Korean American hip hop singers in late 90s. This research will identify the primary cause of the diction fusion phenomenon in the course of history of K-Pop.

This study investigates why Korean English speakers misunderstand the English article system, which article Korean EFL learners use more accurately in their English writings, and implications for English writing instruction from Korean EFL learners' utterances. There have been numerous studies on the acquisition of English article system by non-native English speakers. Those studies agree that acquiring English articles is difficult for learners of English as a second language. As a result, in this study, many English learners use the definite and indefinite articles a/an. Many wrote articles from their writings, and occasionally, errors of excessive use of definite articles occurred. Through this, this paper investigates how a Korean English learner whose native language has no articles chooses the English article system in speech. It is based on the elicited production of the Korean English learner and suggests some implications for teaching English writing in the classroom. When English instructors teach Korean English learners to write English, it is more important than anything else to practice the correct usage of definite articles or indefinite articles.

This study, from the perspective of Learning with AI, aimed to explore the educational applicability of writing evaluation criteria generated by artificial intelligence. Specifically, it sought to systematically analyze the similarities and differences between AI-generated criteria and those developed by humans. The research questions for this study were set as follows: 1) What characteristics do the writing evaluation criteria generated by AI tools have? 2) What similarities and differences exist between the writing evaluation criteria generated by humans and AI tools? GPT and Claude were selected as representative AI tools, and they were tasked with generating writing evaluation criteria for undergraduate students. These AI-generated criteria were then compared with human-created criteria. The results showed a commonality: Both humans and AI-tools placed the highest importance on categories related to content. However, while humans evaluated based on three main categories - content, organization, and language usage - the AI tools included additional categories such as format and citations, original thinking, and overall impression. In general, human tended to include more detailed items within each evaluation category, while AI tools presented more concise items. Notably, differences were observed in language-related aspects and scoring systems, which were influenced by the AI tools being developed based on English. This study offers important insights into the development of collaborative evaluation models between humans and AI, and it explores the potential role of AI as a complementary tool in educational assessment in the future.

G-code, another name of ISO6983, has been a popular commanding language for operating machine tools. This G-code, however, limits the usage of today's fast evolving high-performance hardware. For intelligent machines, the communications between machine and CAD/CAM departments become important, but the loss of information during generating G-code makes the production department isolated. The new standard for operating machine tools, named STEP-NC is just about to be standardized as ISO14649. As this new standard stores CAD/CAM information as well as operation commands of CNC machines, and this characteristic makes this machine able to exchange information with other departments. In this research, the new CNC machine operated by STEP-NC was built and tested. Unlike other prototypes of STEP-NC milling machines, this system uses the STEP-NC file in XML file form as data input. This machine loads information from XML file and deals with XML file structure. It is possible for this machine to exchange information to other databases using XML. The STEP-NC milling machines in this research loads information from the XML file, makes tool paths for two5D features with information of STEP-NC, and machines automatically without making G-code. All software is programmed with Visual $C^{++}$, and the milling machine is built with table milling machine, step motors, and motion control board for PC that can be directly controlled by Visual $C^{++}$ commands. All software and hardware modules are independent from each other; it allows convenient substitution and expansion of the milling machine. Example 1 in ISO14649-11 having the full geometry and machining information and example 2 having only the geometry and tool information were used to test the automatic machining capability of this system.

Unlike face-to-face communication, text-based communication by digital media has limitations that non-verbal elements are eliminated and social presence decrease. To overcome this problem, people try to find solutions which visualize emotion and situation by using emoticons, icons, computer language and so on. As most SMS users experience the failure of using emotions on the mobile phone, they need to make up for this point. In this study, we conducted research on the recent mobile fonts situations and surveyed users' perception on SMS fonts as to suggest solutions of expressing and visualizing emotions on the mobile phone, a representative media of personal communication. As a solution of reducing the failure, we conducted a survey on users' perception about fonts and the capability of the expressing emotions by fonts. The survey found that mobile fonts can be used as a method to express human emotion. As a finding, the shape of the font can be used as a method to visualize the emotion through text messaging. In future studies, such a method can be applied to variety of different personal media with the communication method based on text. Those studies can propose different usage for fonts in communication.

The worldwide population is aging rapidly. In this circumstance, Korean society is in need of the urgent comprehensive countermeasures that will help the elderly with their health problems and infection control in their daily life. Universal design has supportive, adaptable, accessible and safety-oriental design standards for the elderly. Is this study, we propose the guidelines of the mobile application development based on the application of the universal design for infection control in the elderly. From the perspective of the universal design, there are several important guidelines including 'generalized access', 'simple and intuitive usage', 'low physical effort', and 'visualized language' based on the KCDC(Korea centers for disease control and prevention) principles for the elderly. These findings show that the guidelines for improving the health literacy of the mobile application via universal design are necessary to enhance the health behavior of infection control for the elderly.

Vast amount of XML documents raise interests in how they will be used and how far their usage can be expanded. This paper has two central goals: 1) easy and fast retrieval of XML documents or relevant elements; and 2) efficient and stable management of large-size XML documents. The keys to develop such a practical system are how to segment a large XML document to smaller fragments and how to store them. In order to achieve these goals, we designed SCOF(Service-centric Object Fragmentation) model, which is a semi-decomposition method based on conversion rules provided by XML database managers. Keyword-based search using SCOF model then retrieves the specific elements or attributes of XML documents, just as typical XML query language does. Even though this approach needs the wisdom of managers in XML document collection, SCOF model makes it efficient both retrieval and management of massive XML documents.

Recently flexible mobile terminals which can freely change the shape of their device are coming out with the development of the flexible display, high capacity memory and system integration technology. The display and the antenna configuration of the future terminals will be altered according to the QoS (quality of service) and the communication environment of users. In particular, we present the new emergence of a multimedia language for human and system to communicate over subjective concepts, intention of users. The intension of users is expressed by changing the shape of their mobile terminal. In addition, antenna configuration is also related to shape of terminal and QoS of users. Therefore, we set up a specific usage scenarios for future mobile terminals and propose an adaptive MIMO (multiple-input multiple-output) schemes that can maximize channel capacity and fit to QoS of users simultaneously.
