This study aims to examine the public's perception of the appropriateness of metaphorical expressions used by medical professionals in medical discourse. A sample of 142 individuals were asked to evaluate the appropriateness of ten metaphorical expressions used by health-care experts. Additionally, questions were posed about the effects of using metaphors. The ten items showed variability in the degree of appropriateness, with metaphors being considered more appropriate when the target was familiar and the similarity between the source and target domains was high. Positive aspects of metaphor use by medical professionals included aiding in understanding, with respondents perceiving such professionals as kind, considerate of patients, and trustworthy. Negative aspects included difficulties in understanding when the similarity between the metaphorical targets was low, requiring lengthy and complex thought processes, and potential misunderstandings of scientific facts. Approximately 15% of respondents reported their own experiences with metaphorical expressions in medical discourse, noting that these metaphors helped them understand the illness and treatment, and induced positive behavioral changes.

The purpose of this study was to examine the use of machine translation by Uzbek-speaking Korean learners, focusing on their usage patterns, attitudes, perceptions, and expectations, as well as identifying the educational implications of using machine translation. An online survey, lasting two weeks, involved 85 Korean language learners from universities in Korea and Uzbekistan. The main findings indicated a high reliance on machine translation for Korean language learning, with the majority of respondents using machine translations to find accurate vocabulary and expressions. Regarding their attitudes towards machine translation, learners mainly utilized it for literal communication, reading, and writing, and were generally satisfied with them, especially as tools for learning spellings and pronunciations. The use of machine translation significantly influenced learners’ confidence, interest in learning, and anxiety reduction. In terms of perception, learners found machine translation effective for learning Korean vocabulary, expressions, and writing, but also perceived machine translators as sources of stress and anxiety. Expectations for using machine translation were high for completing tasks in vocabulary, expression, and writing, but low for improving grammar skills and producing error-free Korean expressions.

In light of the expanding use of technology in education, we attempted to analyze how Korean college students perceived the use of Machine Translation (MT) tools in the classroom. Specifically, this study attempted to explore students’ perceptions of their ability to use MT tools and to measure the reliability of the MT-generated output, along with measuring students’ general sense of confidence in English learning. This research analyzed 183 EFL college students’ responses to an online survey, and a one-way ANOVA was used to test for the differences in the averages of three groups. The results of data analysis revealed that 1) Among beginners, intermediate learners, and advanced learners, those self-identifying as advanced had the highest scores on all the factors measured.; 2) There was a significant mean difference in students’ perceptions of the ability to use MT tools, their beliefs regarding MT’s effectiveness as a learning tool, and affective attitudes towards the use of MT tools between beginner and advanced groups. Based on the findings, pedagogical implications for the effective use of MT tools in the Korean EFL classrooms, and suggestions for future research were presented.

To clarify the concepts of dialects, vernacular and regional languages used with similar meanings, this study attempted to reveal the usage patterns and concepts of these expressions based on written corpus. The written corpus of printed newspaper articles from the online Naver News Library that archived newspaper articles from 1920 to 1999 and the news article corpus crawled by the online Naver News portal from January 1, 2004 to December 31, 2021 were extracted and analyzed. In particular, this paper analyzed the relationship between collates and keywords based on the corpus linguistic research methodology of the news article corpus for the past eighteen years and how they were being used in official records and press documents by corresponding with the 'dialects, vernacular, and regional languages' in socio-linguistic terms of modern Korean. The results are summarized as follows. First, the concept of linguistic norms that a dialects have terms corresponding to the words or standard languages was established after the 1930s. Second, in the library of newspaper articles published in the 20th century, dialects or vernaculars were perceived as negative objects to be removed in preparation for standard language. Third, it can be seen that the positive value judgment on 'vernacular' has increased in the corpus of news articles over the past decade. Fourth, dialects and vernacular, regional language, and standard language were used to be compatible with each other, and it can been seen that dialects were mainly used in academic contexts and vernacular were mainly used in everyday contexts. Fifth, it can be confirmed that the positive perception of standard language has been maintained in the 20th-century newspaper article corpus and the 21st-century news article corpus for the last eighteen years after the recognition of standard language.

독립형 VR기기가 활발히 개발되기 전 스마트폰을 HMD로 만들려는 움직임이 있었고 구글의 카드보드와 삼 성의 기어 VR이 그 예이다. 하지만 독립형 VR기기의 출시와 모바일 기기의 한계로 현재는 대부분 AR로 전 환되어 사용되었다. 그렇지만 지난 10년간 모바일 VR과 AR의 기술도 발달했지만, 그동안 모바일 기기의 성 능도 향상되었다. 따라서 발달한 기술들을 바탕으로 손 추적을 뛰어넘어 손동작 분류를 모바일 기기에서 기 존의 VR과 AR 콘텐츠와의 상호작용에 활용할 수 있다. 본 논문에서는 Manomotion을 이용하여 2D 또는 3D 의 골격을 추적하고 손동작 분류를 구현했으며 게임을 사용하여 검증하였다.

Future autonomous vehicles need to recognize the ego lanes required for lane change and the side left and right lanes differently. Therefore, multi-lane recognition is needed. In this study, using the YOLO network, mainly used for object recognition, the proposed method recognizes the ego, left and right side lanes as different objects and identifies the correct lanes. As a result of the performance evaluation on the TuSimple test data, the proposed method recognized the ego lanes and the left and right side lanes differently. It showed very stable lane recognition results. And by detecting lanes that do not exist in the ground truth of TuSimple data, the proposed method is very robust in lanes detection. Nevertheless, studies related to learning data reinforcement in which lanes are located in the center or at the left and right edges of the image and accurate network learning for lanes are needed.

In this study, the multi-lane detection problem is expressed as a CNN-based regression problem, and the lane boundary coordinates are selected as outputs. In addition, we described lanes as fifth-order polynomials and distinguished the ego lane and the side lanes so that we could make the prediction lanes accurately. By eliminating the network branch arrangement and the lane boundary coordinate vector outside the image proposed by Chougule’s method, it was possible to eradicate meaningless data learning in CNN and increase the fast training and performance speed. And we confirmed that the average prediction error was small in the performance evaluation even though the proposed method compared with Chougule’s method under harsher conditions. In addition, even in a specific image with many errors, the predicted lanes did not deviate significantly, meaningful results were derived, and we confirmed robust performance.

This study aimed at elementary, middle, and high school dietitians who purchase ingredients for school meals. Therefore, for the study, the awareness and usage of nutritional information by 108 teachers and dieticians on 5 hazard-free meals using multivariate analysis of variance were investigated during May 18~21, 2021. Among the five questions that asked the general perceptions of school meal dietitians of 5 hazard-free meals, the perception that the “5 hazard-free foods can be easily distinguished” was the lowest. Problems were associated with using the 5 hazard-free meals such as “expensive price,” “no variety in items,” “disruption in the supply and demand,” “inconsistent quality,” and “lack of taste,” in that order. Therefore, to improve 5 hazard-free school meal service, it is necessary to not only lower the price burden by providing subsidies to schools but also improve the development and distribution structure of various 5 hazard-free foods.

This study aimed to investigate the use of environmentally friendly agricultural products (EFAPs) in Chungcheongbuk-do and the perception and satisfaction of school dietitians with EFAPs. The study survey was conducted from April to Jun 2018. Among 195 dietitians, 54.4% were nutrition teachers and 51.3% were working in elementary schools. Of the participants, 65% answered that the percentage of EFAPS in the total food cost was 10~30%. The most used EFAP food group was grains (64.6%), followed by vegetables (26.2%). The main reasons for using EFAPs were subsidies for EFAPs from local governments (85.1%) and students’ health (52.3%). The average daily subsidy for EFAPs from the local governments was 201~500 won at 45.1%, and 200 won or less at 34.9%, which was based on one meal per student. In questions on satisfaction with using EFAPs, satisfaction with safety (3.93 out of 5 points) scored the highest, followed by nutrition (3.74), freshness (3.70), appearance (3.32), diversity (2.85), and price (2.78). Therefore, to expand the use of EFAPs in school food service, it is necessary to expand the provision of subsidies and increase EFAP production diversification.

The purpose of this study is to examine a corpus regarding the use of discriminatory language and its perceptions. First, we examined informal job titles that indicate social views regarding the respective workers, and then we analyzed expressions indicating negative perceptions as well as negative expressions about occupations and tasks to determine negative views or attitudes toward the workers. Summarizing the results of the analysis, ganhowon(nurse) and cheongsobu(cleaner) as inappropriate titles, nogada(physical labor) and gongdori/gongsuni(factory boy/girl) as expressions of negative perception, and nogada and wunjeonsu(driver) in negative expressions related to occupations and work occur with high frequency. Ganhowon is used with titles for women like eonni(older sister), agassi(lady), and Miss ○, cheongsobu and pachulbu(day maids) with the titles ajumma(tannie) and ajeossi(older man), wunjeonsu and gongsuni with the epithets nom(jerk) and nyeon(bitch), and nogada with the titles ilggun(workers) and inbu(laborers), and such terms as jjapsae(the fuss) with a epithet saeggi(jerk/bleeder) are used mainly as inappropriate titles. Bad behavior, deprecatory social treatment, and negligent discrimination are conveyed in these expressions of negative perception. The expressions related to occupation and work were mainly used for professionals doing less respected or socially lower work or who do not work well, and there were many expressions indicative of low status or lower rank in the job hierarchy. Lastly, references to appearance and sexuality were those most frequently used in expressions conveying other occupational discrimination, and were found to be used mainly for ganhowon and gongsuni who are young women.
