목적 : 본 연구에서는 HMD VR을 사용해 발생한 사이버 멀미와 양안시 기능이 상관관계를 보이는지 알아보고 자 하였다. 방법 : 근거리 시력에 무리가 없는 20~40대 성인 52명을 대상으로 VR 콘텐츠 이용 전 양안시 기능을 측정하기 위해 수평사위도, 조절 근점, 폭주 근점, 양안조절용이성, 입체시, 상대조절력검사를 시행하였다. 광학 흐름 요소로 구분한 세 가지 VR 콘텐츠를 선정하여 대상자에게 사용하도록 하고 Virtual reality sickness questionnaire을 통해 VR 콘텐츠 이용 전과 후의 사이버 멀미를 측정하였다. 양안시 기능과 사이버 멀미에 대한 상관분석을 실시하 였다. 결과 : VR 콘텐츠 사용 후 콘텐츠 T와 R은 모든 항목에서 사이버 멀미(p<0.001)는 유의하게 증가하였다. 콘텐츠 B의 안구운동에서는 유의한 차이가 없었다. 상관분석에서는 근거리 사위가 콘텐츠 T의 방향감각상실(p< 0.050), 전체 VRSQ(p<0.050)와 음의 상관관계를 보였으며, 콘텐츠 R의 안구운동불편(p<0.050)과 유의한 상관관 계가 나타났다. 양안조절용이성은 콘텐츠 T의 전체 VRSQ(p<0.050)와 양의 상관관계를 보였다. 이 외에 다른 양안 시 기능은 사이버 멀미 요인과 유의한 상관관계를 보이지 않았다. 결론 : 양안시 기능은 사이버 멀미와의 결과로 사용자의 개인적 특성이나 양안시 기능 자체가 사이버 멀미에 미 치는 영향보다 3D를 구현하는 콘텐츠의 광학 흐름 요소가 미치는 영향이 더 높다는 것으로 사료된다. 향후 연구에 서는 VR 콘텐츠의 시각 요소와 시지각에 대한 요소가 고려되어야 할 필요성이 있는 것으로 사료된다.

Among Japan's agriculture, forestry, fisheries and regional revitalization plans established in June 2018, the key matters related to aquaculture include ① a new perspective on the sponge use system for the development of aquaculture and coastal fisheries, ② a comprehensive strategy for growth and industrialization of aquaculture, and ③ expansion of suitable aquaculture areas. There are four countermeasures including ④ research and development trends. In accordance with these key points, the Japanese government established a comprehensive strategy for aquaculture growth and industrialization by strategically setting aquaculture items in consideration of domestic and international demand, establishing a comprehensive strategy from production to sales and export, and then working in earnest to promote the aquaculture industry. This study analyzes environmental changes surrounding aquaculture in Japan and trends in fish farming and marine products, and summarizes the key points of the June 2018 Agriculture, Forestry, Fisheries and Regional Revitalization Plan to suggest measures that can be utilized in Korea’s aquaculture policy.

This study conducted a critical discourse analysis (CDA) of Maria Leonor “Leni” G. Robredo’s presidential proclamation bid considering differing ideologies between two opposing political parties in the Philippines. Robredo employed language to persuade people to support her ideologies and, ultimately, to cast their votes for her. Analyzing her speech through Fairclough’s three-dimensional CDA model yielded the following several key insights. First, the textual analysis of Robredo’s proclamation bid revealed multiple personal and impersonal motivations in using linguistic markers such as personal pronouns, mood, and modality. Second, the processing analysis of Robredo’s political discourse displayed her lexical choices and use of rhetorical norms such as metaphors, repetition, and three-part lists to persuade people to change their views on the government. Finally, the social analysis of Robredo’s proclamation speech revealed her ideologies as a political leader, which became the basis for constructing a self-identity relevant to her orientation of power. This analysis of Robredo’s political discourse through CDA explored the relationship between language, ideologies, and power. The findings of this study are expected to stimulate listeners to critically observe the verbal political behaviors of speakers.

Acknowledging the limited opportunities faced by learners of Korean in the US, this study investigates the efficacy and challenges of immersive Korean language-focus residential programs in US college dormitories. Through an examination of a Korean language dormitory (called K-house) at a Midwestern university in the US, the current study sheds light on the optimal experiences and effective immersive environments that college langauge dormitory programs in the US can foster for both linguistic and cultural learning of Korean. By delving deeper into the specific programming and experiences of K-house residents, the study demonstrates that K-house facilitates access to Korean language and culture, enhances motivation of Korean language study, and cultivates a sense of belonging to the K-house community among K-house residents. Additionally, the findings of this study provide valuable insights for designing effective Korean language dormitory programs that promote language and cultural immersion in the context of teaching and learning Korean as a foreign language. Furthermore, this study offers suggestions for future research in this area.

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.

This study investigated and analyzed the recognition and needs for Korean communication competency among non-Korean learners who participated in an online Korean language course. To this end, the importance, performance, and necessity of the categories of communication competency recognized by Korean language learners were measured, and then IPA(Importancce-Performance Analysis: Martilla & James, 1977) analysis and Borich’s needs analysis(Borich, 1980) were used. After implementation, we examined whether there were differences in outcomes depending on learner variables. After examining the sub-items, it was found that there were differences in importance, current level, and need depending on the learner’s home country, and there were differences in current level, demand, and necessity depending on academic background and Korean language proficiency. In addition, there are differences in need depending on the learner’s reason for learning Korean, so it is necessary to respond to individual learnier’s needs according to learner variables when designing curriculum for online foreign language learners of Korean.

This study analyzes the fifth edition of the enhanced spelling of the Indonesian language (EYD V) by comparing it with the original Indonesian spelling system (EBI) in terms of the use of character and punctuation. Specifically, it presumes that the frequent occurrence of errors in the Indonesian spelling systems is related to both indifference in Indonesian orthography and recurrent orthographic revisions. Based on this premise, it investigates differences between the original EBI, officially announced in 2015, and EYD V, the latest Indonesian spelling system, in terms of the use of character and punctuation. The analytic results found that EYD V includes several new elements, such as the introduction of a monophthong eu and the use of consonants q, x, and y at the end of words. Furthermore, it was found that EYD V provides the revised and supplemented contents compared to the original EBI from multiple perspectives by implementing enhanced consistency and timeliness in descriptions and error correction. The outcomes of this study are expected to serve as essential data for Indonesian writing education and as comparative data for discussions on Malay orthography in relation to Indonesian orthography.

This research focuses on teaching Arabic to Jewish students in Jerusalem, a city of significant cultural and religious importance for both Arabs and Jews, especially under the backdrop of the prolonged conflict between these communities. The study asserts that the political complexity inherent in this context gives rise to unique challenges in teaching Arabic in Jewish schools in Jerusalem, which is influenced by conflict and racism. These factors contribute to the formation of a psychological barrier within the Arabic educational process. The objective of the study is to provide a comprehensive overview of the status of Arabic teaching to Jews in Jerusalem, emphasizing the unique aspects of this case and addressing the challenges encountered in the process. The outcomes of this research showed that the demographic composition of Jerusalem, with concentrations of both Arabs and extremist Jews, contributes to the distinctive nature of this case compared to other Israeli-occupied cities. This demographic factor influences the goals of teaching Arabic to Jews in Jerusalem and, concurrently, intensifies the challenges faced in this educational process, setting it apart from similar endeavors in different locations.

This study contrasted the response relationship and constraints of the Chinese phrase ‘S+給+NP1+V+NP2’ between ‘给’ and Korean ‘에 게’. Both ‘给’ and Korean ‘에게’ have something in common that they can lead to the objects of grant, communication, or benefit, but there were also certain constraints on the response relationship. In order to clarify this constraint, this study first classified semantic items according to the following nouns and trailing predicates of the phrase ‘S+給+NP1+V+NP2’ and their semantic relationships. Based on this, this paper compares Chinese ‘给’ with Korean ‘에게’ and analyzes the differences between the two. As a result of the analysis, the correspondence between the two was affected by the following constraints. First, the correspondence is established if the object ‘에 게1’ and ‘给1’ are living beings. Second, when ‘에게1’ contains [+benefit] or [+transmission] positive semantics, it is impossible to communicate with ‘给2’ to each other. Third, when both the subject of action and the posterior object are living things, there is a correspondence between ‘에게3’ and ‘给5’. However, there is a difference in the meaning of ‘给5’ and ‘에게3’ in Korean. ‘给5’ has a function that emphasizes the posterior predicate, but ‘에게3’ in Korean does not have such a function.

Previous studies on English spelling have investigated the types of spelling errors and their frequencies, and studies on why learners made those errors have been called for. This study aimed to identify factors leading to errors in the English-spelling of Korean elementary school students. The factors were investigated by using the following methods: A total of 130 students from O Elementary School were given three types of word-writing tasks: dictation of single words, dictation of short sentences, and writing words as many as the students can based on pictures depicting familiar scenes. The errors in their writing samples were classified into five types. The students were interviewed about why they made those errors. The results showed that the errors were influenced by the factors: the students’ first language, background knowledge, pronunciation, and morphological reasons. The results suggest that if teachers understood these factors, they would be able to explore better teaching methods for reducing errors in English spelling, and that future research could apply these factors for further investigations.

MEPC 80차 회의에서 IMO는 더욱 강화된 온실가스 감축 전략을 제시하였다. 기존의 72차 회의에서 제시하였던 초기전략보다 구체적이고 강화된 감축 전략이다. IMO는 2050년 무렵까지 국제 해운으로부터 온실가스 배출을 ‘Net Zero’에 도달하도록 전략을 세웠다. 이 논문에서는 대표적인 친환경 연료로 구분되는 LNG, 수소, 메탄올, 암모니아의 위험도 평가를 진행하였다. 전문가들의 설문조사를 통한 결과를 퍼지 기법을 적용하여 주관적인 모호성을 해결하였다. 또한 TOPSIS 기법을 통해서 퍼지의 긍정적인 해와 부정적인 해를 도출하였 다. 이를 통해서 Vertex 방법을 이용하여 대체 연료의 근접계수 값을 최종적으로 구하여 결정하였다. 그 결과, 메탄올, LNG, 수소, 암모니 아 순으로 선호하였다. 이 연구는 제안된 접근 방식이 대체 연료를 결정을 위한 집단 의사결정 방법으로 이용할 수 있음을 보여준다.

본 연구는 간호대학생을 대상으로 강점인식과 진로관여행동과의 관계에서 진로적응성의 매개효 과를 확인하고자 수행되었다. 연구대상은 G광역시와 J도에 소재한 대학교 3곳의 간호대학생 284명을 대상 으로 하였다. 자료는 기술통계, t-test, ANOVA, Pearson 상관분석 및 Baron과 Kenny의 3단계 매개 회귀 분석을 이용하였고, Sobel test로 검증하였다. 강점인식과 진로관여행동사이에서 진로적응성은 부분매개효 과를 나타냈으며(Z=6.66, p<.001), 강점인식 수준이 높을수록(β=.24, p<.001), 진로적응성이 높을수록(β =.49, p<.001), 진로관여행동 수준이 높아지며, 진로관여행동을 설명하는 설명력은 47%이었다. 간호대학 생의 진로관여행동 수준의 향상을 위해서는 진로적응력 함양을 위한 구체적인 행동전략과 더불어 진로교 육 및 상담을 통해 개인의 강점을 인지할 수 있는 지도전략이 필요하다.

The present study aimed to explore how pre-service teacher’s individual regulatory focus orientation, currently emerging as an interesting learner variable for language learning, could influence their Englishspeaking abilities. English teaching demonstration videos of 67 pre-service teachers were analyzed in terms of pronunciation, accuracy, and fluency. The regulatory focus orientations of participants were evaluated using a questionnaire. The results of data analysis, using multiple regression analysis, indicated that promotion-focus orientation was a significant positive predictor for pronunciation, fluency (words per minute, ratio of dysfluency), and accuracy (lexical errors, ratio of error-free AS-units). On the other hand, prevention-focus orientation did not emerge as a statistically significant factor affecting accuracy. However, it was observed to have a negative influence on both pronunciation and fluency. In light of the research findings that highlight the favorable impact of a promotion-focus orientation, suggestions were made for future teacher training programs aimed at enhancing the English proficiency of pre-service teachers.

해상풍력발전 시장의 성장과 함께 해상풍력발전기 설치 선 시장에 대한 기대감이 커지고 있다. 해상풍력발전 시장 내 2030년까 지 약 100척의 설치 선이 필요할 것으로 전망되고 있다. 척당 가격이 3,000∼4,000억 원이라서 일반 운반선보다 고부가가치 시장이다. 특 히, 풍력발전기 용량이 11MW 이상의 대형 설치 선의 수요가 커지고 있다. 중국을 중심으로 아시아 해상풍력발전기 시장의 급성장으로 이 지역에서 운용 가능한 설치 선에 대한 발주에 대한 협의가 많다. 아시아권역 대부분의 해저 지질은 지지 반력이 작은 점토층으로 구성되 어 있다. 이러한 특성에 의해서 설치 선이 작업을 위해 수면 밖으로 오르고 내림 시 스퍼드캔(Spudcan)과 레그(Leg)의 관입 깊이가 크게 발 생한다. 연구에서는 최소 3m에서 최대 21m까지 관입 변수를 이용하여 관입 깊이에 따른 고유 진동 주기, 레그의 구조 안전성 평가 그리고 전복 안전성 지수를 평가하였다. 관입 깊이가 증가하면 고유 진동 주기가 짧아지고, 레그의 모멘트 길이가 짧아져서 구조 강도의 여유 치 가 증가한다. 모든 입사각에서 전복 모멘트에 대해 안전하며, 최댓값은 270도에서 발생한다. 본 연구를 통하여 검토된 조건들은 연약 지반 에서 설치 선의 운용 절차서를 작성 시 관입 깊이에 따라서 레그를 어떻게 운용해야 하는지 판단할 수 있는 중요한 자료로 활용할 수 있 다. 결론적으로 관입 깊이에 따른 레그 구조 안전성을 정확히 파악하는 것은 설치 선의 안전과 직결된 문제이다.

This study aimed to explore the impact of AI image generators on the affective factors of college-level English learners and the correlations among these factors. During a four-week instructional period, 65 participants were asked to use Midjourney as an AI tool for their user experiences. Affective factors including interest, confidence, and participation were measured through pre- and post-surveys. Using Jamovi for analysis, significant improvements were discovered across all affective factors. Noteworthy improvements occurred in confidence, indicating a favorable impact by AI-generated images on English learning. Additionally, correlation analysis demonstrated significant positive relationships between interest and confidence, as well as confidence and participation. This confirms the interconnected nature of these affective elements in the learning process. The findings suggest that the educational use of image-generating AI tools can beneficially influence English learners’ affective domains. The study calls for further investigation into the pedagogical applications of image AI to foster a more interactive, engaged, and self-assured attitude towards language learning.

This study aimed to explore sustainable fashion design plans and directions by analyzing Marine Serre’s collection. Previous research was reviewed to derive classifications of the aesthetic characteristics of sustainable fashion design. This classification was then used to analyze the characteristics of the Marine Serre collection. Design analysis was conducted on Marine Serre’s 2018 FW to 2023 SS collections. Marine Serre’s sustainability characteristics are functionality, surprise, handicraft, and inclusion. The results are as follows. First, functionality is the highest among the four characteristics and includes the functionality of movement, the functionality of form, and futurism. This characteristic was observed in the use of all-in-one body suits, pockets, and workwear, showing the will and values of designers who value daily activity. Second, surprise includes the scarcity of materials and the unexpectedness of composition. The value of the clothing is enhanced by the use of scarce materials not typically used in clothing. In addition, Marine Serre is highly regarded for expanding clothing into life by incorporating material upcycling into the theme of the collection. Third, handcrafted features include exaggerated decorations, logo, retro designs, and natural properties, and intentional utilization is differentiated. Marine Serre’s signature pattern suggests a suitable expression for the fabric to use the crescent moon for the season. Fourth, the collection expresses themes of inclusivity and cultural diversity. The results indicate that Marine Serre wants to contribute to a better future characterized by global coexistence.
