본 논문은 청일전쟁기 『국민신문(国民新聞)』의 특파원으로 종군한 마 쓰바라 이와고로(松原岩五郎)의 『정진여록(征塵餘録)』(1896)에 대해 분 석하고 작품 속에 나타난 19세기 후반 조선에 대한 작가의 인식을 살 펴본다. 식민지 조선의 여행과 관련된 대부분의 연구에서 여행의 기록 물들은 제국주의의 산물이자 식민주의의 프로파간다 전략으로 읽혀왔 다. 본 논문은 청일전쟁 종군기를 분석함에 있어 종군기자의 문학가로 서의 양심이나 개인의 신념에 따른 독자적인 인식이 담겨있을 것이라 는 점과 청일전쟁 시기 조선에 대한 다양한 정보가 대중화되지 않았던 까닭에 조선의 이질적인 문화를 접하는 데 가치중립적인 시선이 있었 을 것이라는 점을 전제로 하여 텍스트를 분석한다. 분석의 결과 마쓰바 라는 하층민의 생활상에 대한 개인적인 관심과 식민지 탐험에 대한 사 명감 등으로 조선과 조선인을 바라보는 시선에 있어서도 일종의 연민 의 인식이 있었다는 점과 그가 사실적인 내용을 기록하되 미개나 야만 성, 낙후성과 연관 지어 문화 지체의 척도로 삼지 않았고 우열이나 멸 시와 같은 시선을 배제하였다는 점에 대해 알 수 있었다.

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.

본 논문은 2019년부터 2023년 사이에 있었던 칠레 헌법제정 과정을 국민참여의 관점에서 분석하였다. 칠레 사회는 2019년 사회적 대폭발을 계기로 헌법을 새로 쓰는 데 합의하였다. 헌법상 기본권 보장을 목표로 헌법제정을 시도하였으나, 두 번의 시도 모두 부결되었다. 남녀동수 제헌 의회 구성, 원주민 대표성 강화, 시민참여 메커니즘 제도화 등 헌법제정 의 절차적 민주성이 높았다. 그러나 정당을 배제한 제헌의회를 구성함으 로써 제헌의원의 전문성이 떨어지고 국민들과의 목표가 불일치하여 국민 들의 요구를 헌법안에 담아내지 못했다는 비판을 받았다. 정당대표성과 제정기관의 전문성을 강화하여 2차 시도를 하였으나 헌법에 인간존엄성 을 담아내지 못했다. 헌법안 작성 기간이 너무 짧았고, 국민의 보편적 요 구와 거리가 먼 보수정당의 가치가 지나치게 반영되었기 때문이다. 또한 짧은 작성 기간과 헌법안 채택 방식은 숙의·심의보다는 속도있는 표결을 강조했다. 그러므로 모든 중요한 정치권력들이 헌법제정 과정에 균형있 게 참여하여 숙의·심의할 수 있는 제도적 보완 방안을 모색해야 할 것이 다.

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.

본 연구는 남북한 공영방송국의 날씨방송 영상을 비교·분석하기 위한 연구이다. 이를 위하여 먼저 날씨방송을 이론적으로 고찰하고, 지난 1년 간 우리나라 공영방송인 KBS 뉴스의 날씨방송과 북한 공영방송인 조선중앙TV 뉴스의 날씨방송을 연구 대상으로 삼아, 영상구성과 의미연결망분석을 실시하 였다. 결과는 다음과 같았다. 첫째, 우리나라 날씨방송은 북한 날씨방송에 비 하여 약 3배 정도 짧게 구성되었다. 둘째, 우리나라 날씨방송은 ‘기온’, ‘서울’ 등이 의미연결망의 중심부에 있었고, 북한 날씨방송은 ‘지역’, ‘기온’이 의미 연결망 중심부에 있었다. 셋째, 우리나라 날씨방송이 전달하는 날씨 건강주의 정보는 ‘대기질’이었고, 북한은 ‘지자기’로 분석되었다. 이를 통하여 우리나라 날씨방송은 그 길이가 짧고 주요도시를 중심으로 한 빠른 전개가 특징이었던 반면, 북한 날씨방송은 그 길이가 길고 지역을 중심으로 한 느린 전개가 특징 이었다. 또한 건강주의 정보로 우리나라는 미세먼지 등 대기질 정보를 건강주 의 정보로 전달하는 반면, 북한은 협심증, 고혈압 등 순환기질병 지자기 정보 를 건강주의 정보로 전달하고 있었다. 끝으로 본 연구는 기후변화 및 기후위 기의 시대에 들어, 한반도를 공유하고 있는 남북한 공영방송국의 날씨방송이, 향후 어떤 지점을 어떻게 교류·개선할 수 있는지 추가적인 논의체계가 필요할 수 있다는 점을 밝히며 본 연구를 마쳤다.

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.

이 연구는 구(舊)일본해군의 군사적 요충지 역할을 맡은 군항도시 사세보 (佐世保)가 관광도시로 전환되는 과정에 기반을 두고 있다. 사세보는 1889 년 7월 진수부(鎮守府)가 개청된 이래 군사 전략적 요충지로 자리잡았다. 1946년 다나카 마사스케(田中正輔) 시장의 취임 이후, 군항도시의 이미지 를 벗고자 평화산업항만도시의 실현을 위해 관광산업을 추진하였고 사세보 주변 해역을 포함한 서해 일대를 국립공원으로 지정받기 위해 최선의 노력 을 다했다. 하지만 사이카이(西海)국립공원 지정 논의가 한창 진행된 시기 인 1950년 한국전쟁이 발발하였고 미국에 의해 일본의 재무장을 촉진 시 키는 계기가 된다. 1950년 7월 맥아더에 의해 해상보안청이 설치되었고 그 총감부가 사세보에 배치된다. 니시오카(西岡) 현(県)지사와 다나카(田中) 시 장은 지역경제를 고려하여 군상(軍商)항이라는 두 마리 토끼를 잡겠다는 목표로 의지를 표명했다. 1955년 여러 난관을 뚫고 서해 일대가 만장일치 로 국립공원 1순위로 결정되었고 3월 16일 정식으로 지정되었다. 본 논문 은 사세보시가 군항도시에서 관광도시로 전환하기 위하여 추진했던 사이카 이(西海)국립공원 유치 활동과 지정 과정을 고찰하고자 한다. 아울러 동아 시아의 역사 속에서 사세보라는 군항도시가 평화산업항만도시로 변천되어 가는 과정을 규명하고자 한다.

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.

In this study, we investigated the microstructure and piezoelectric properties of 0.96(K0.456Na0.536)Nb0.95Sb0.05-0.04 Bi0.5(Na0.82K0.18)0.5ZrO3 (KNNS-BNKZ) ceramics based on one-step and two-step sintering processes. One-step sintering led to significant abnormal grain (AG) growth at temperatures above 1,085 °C. With increasing sintering temperature, piezoelectric and dielectric properties were enhanced, resulting in a high d33 = 506 pC/N for one-step specimen sintered at 1,100 °C (one-step 1,100 °C specimen). However, for one-step 1,115 °C specimen, a slight decrease in d33 was observed, emphasizing the importance of a high tetragonal (T) phase fraction for superior piezoelectric properties. Achieving a relative density above 84 % for samples sintered by the one-step sintering process was challenging. Conversely, two-step sintering significantly improved the relative density of KNNS-BNKZ ceramics up to 96 %, attributed to the control of AG nucleation in the first step and grain growth rate control in the second step. The quantity of AG nucleation was affected by the duration of the first step, determining the final microstructure. Despite having a lower T phase fraction than that of the one-step 1,100 °C specimen, the two-step specimen exhibited higher piezoelectric coefficients (d33 = 574 pC/N and kp = 0.5) than those of the one-step 1,100 °C specimen due to its higher relative density. Performance evaluation of magnetoelectric composite devices composed of one-step and twostep specimens showed that despite having a higher g33, the magnetoelectric composite with the one-step 1,100 °C specimen exhibited the lowest magnetoelectric voltage coefficient, due to its lowest kp. This study highlights the essential role of phase fraction and relative density in enhancing the performance of piezoelectric materials and devices, showcasing the effectiveness of the two-step sintering process for controlling the microstructure of ceramic materials containing volatile elements.

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.

Silicon carbide (SiC) has emerged as a promising material for next-generation power semiconductor materials, due to its high thermal conductivity and high critical electric field (~3 MV/cm) with a wide bandgap of 3.3 eV. This permits SiC devices to operate at lower on-resistance and higher breakdown voltage. However, to improve device performance, advanced research is still needed to reduce point defects in the SiC epitaxial layer. This work investigated the electrical characteristics and defect properties using DLTS analysis. Four deep level defects generated by the implantation process and during epitaxial layer growth were detected. Trap parameters such as energy level, capture-cross section, trap density were obtained from an Arrhenius plot. To investigate the impact of defects on the device, a 2D TCAD simulation was conducted using the same device structure, and the extracted defect parameters were added to confirm electrical characteristics. The degradation of device performance such as an increase in on-resistance by adding trap parameters was confirmed.

Scanning probe microscopy (SPM) has become an indispensable tool in efforts to develop the next generation of nanoelectronic devices, given its achievable nanometer spatial resolution and highly versatile ability to measure a variety of properties. Recently a new scanning probe microscope was developed to overcome the tip degradation problem of the classic SPM. The main advantage of this new method, called Reverse tip sample (RTS) SPM, is that a single tip can be replaced by a chip containing hundreds to thousands of tips. Generally for use in RTS SPM, pyramid-shaped diamond tips are made by molding on a silicon substrate. Combining RTS SPM with Scanning spreading resistance microscopy (SSRM) using the diamond tip offers the potential to perform 3D profiling of semiconductor materials. However, damage frequently occurs to the completed tips because of the complex manufacturing process. In this work, we design, fabricate, and evaluate an RTS tip chip prototype to simplify the complex manufacturing process, prevent tip damage, and shorten manufacturing time.

Nanoparticles are commonly used to avoid the opaque white color of TiO2 based sunscreen. However, a dispersing agent is typically required because of the tendency of the nanoparticles (NPs) to agglomerate. Stearic acid is one kind of dispersing agent often used for sunscreen products. However, according to the MSDS data sheet on stearic acid, stearic acid is highly hazardous to aquatic life and causes irritation on human skin. To avoid this problem, in this study a safer organic dispersing agent extracted from Korean seaweed has been studied to disperse TiO2 nanoparticles, and further use as an active agent in sunscreen products. The presence of phytochemicals in seaweed extract, especially alginate, can disperse TiO2 nanoparticles and improve TiO2 dispersion properties. Results show that seaweed extract can improve the dispersion properties of TiO2 nanoparticles and sunscreen products. Reducing the agglomeration of TiO2 nanoparticles improves sunscreen properties, by making it less opaque white in color, and increasing UV protection value. It was also confirmed that adding seaweed extract into sunscreen products had no irritating effects on the human skin, making it more desirable for cosmetics application.

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.

The optimization of deacetylation process parameters for producing chitosan from isolated chitin shrimp shell waste was investigated using response surface methodology with central composite design (RSM-CCD). Three independent variables viz, NaOH concentration (X1), radiation power (X2), and reaction time (X3) were examined to determine their respective effects on the degree of deacetylation (DD). The DD of chitosan was also calculated using the baseline approach of the Fourier Transform Infrared (FTIR) spectra of the yields. RSM-CCD analysis showed that the optimal chitosan DD value of 96.45 % was obtained at an optimized condition of 63.41 % (w/v) NaOH concentration, 227.28 W radiation power, and 3.34 min deacetylation reaction. The DD was strongly controlled by NaOH concentration, irradiation power, and reaction duration. The coefficients of correlation were 0.257, 0.680, and 0.390, respectively. Because the procedure used microwave radiation absorption, radiation power had a substantial correlation of 0.600~0.800 compared to the two low variables, which were 0.200~0.400. This independently predicted robust quadratic model interaction has been validated for predicting the DD of chitin.

Thin films of yttria-stabilized zirconia (YSZ) nanoparticles were prepared using a low-temperature deposition and crystallization process involving successive ionic layer adsorption and reaction (SILAR) or SILAR-Air spray Plus (SILAR-A+) methods, coupled with hydrothermal (175 °C) and furnace (500 °C) post-annealing. The annealed YSZ films resulted in crystalline products, and their phases of monoclinic, tetragonal, and cubic were categorized through X-ray diffraction analysis. The morphologies of the as-prepared films, fabricated by SILAR and SILAR-A+ processes, including hydrothermal dehydration and annealing, were characterized by the degree of surface cracking using scanning electron microscopy images. Additionally, the thicknesses of the YSZ thin films were compared by removing diffusion layers such as spectator anions and water accumulated during the air spray plus process. Crack-free YSZ thin films were successfully fabricated on glass substrates using the SILAR-A+ method, followed by hydrothermal and furnace annealing, making them suitable for application in solid oxide fuel cells.

고분자 분리막의 대표적인 형태 중 하나인 평판형 분리막은 제조가 용이하여 실험실에서 분리막 소재 연구에서부 터 실제 상용 분리막 생산에 이르기까지 널리 활용되는 분리막의 형태이다. 정밀여과 및 한외여과 등에 사용되는 평판형의 다공성 고분자 분리막은 주로 상분리 공정을 통해 제조할 수 있으며, 여기에는 비용매 유도 및 증기 유도 상분리 공정이 활 용된다. 그러나 상분리 공정 특성상 주변 환경과 실험자에 따라 샘플 간 편차가 쉽게 발생하여 재현성의 확보가 어려운 점이 있다. 따라서 개발된 제조기술을 스케일업 및 재현성 확보를 위해 제어된 환경에서 연속식 대면적 제조가 가능한 롤투롤 제 조장치가 필요하며, 본 연구에서는 실험실 스케일의 제조기술을 나이프 및 슬롯다이 롤투롤 공정으로 스케일 업 했을 때 나 타나는 제조 환경 차이에 따른 분리막의 특성 변화를 비교하였다. 최종적으로 연속식 제조공정 인자에 대한 최적화를 통해 대면적 제조 시 분리막의 균일성을 확보하였다.

The lightweight and high strength characteristics of aluminum alloy materials make them have promising prospects in the field of construction engineering. This paper primarily focuses on aluminum alloy materials. Aluminum alloy was combined with concrete, wood and carbon fiber reinforced plastic (CFRP) cloth to create a composite column. The axial compression test was then conducted to understand the mechanical properties of different composite structures. It was found that the pure aluminum tube exhibited poor performance in the axial compression test, with an ultimate load of only 302.56 kN. However, the performance of the various composite columns showed varying degrees of improvement. With the increase of the load, the displacement and strain of each specimen rapidly increased, and after reaching the ultimate load, both load and strain gradually decreased. In comparison, the aluminum alloy-concrete composite column performed better than the aluminum alloy-wood composite column, while the aluminum alloy-wood-CFRP cloth composite column demonstrated superior performance. These results highlight excellent performance potential for aluminum alloy-wood-CFRP composite columns in practical applications.
