혼합원자가 $Sr_xEu_{1-x}FeO_{3-y}$ ($0.00{\leq}x{\leq}$1.00)계의 비화학량론과 물성 연구
민지영,노권선,여철현,Ji Young Min,Kwon Sun Roh,Chul Hyun Yo 대한화학회 1994 대한화학회지 Vol.38 No.12
$Sr_xEu_{1-x}FeO_{3-y}$ (0.00{\leq}x{\leq}1.00)계의 고용체 시료를 $1200^{\circ}C$와 대기압하에서 합성하였다. X-선 회절분석, 열분석, Mohr염 분석 및 Mossbauer 분광분석을 수행하여 합성된 고용체의 구조들을 규명하고 전기 전도도를 측정하여 물성에 관한 논의를 하였다. X-선 회절 분석 결과 x = 0.00, 0.25 및 1.00인 조성계들은 사방정계이고, x = 0.50과 0.75인 조성계들은 입방정계이다. 입방세포로 환산된 격자부피는 x값이 증가함에 따라 증가한다. Mohr염 적정으로 고용체내의 $Fe^{4+}$이온의 몰비 또는 $\tau$값을 결정하고 전기 중성화 조건에 의해 산소 비화학량 또는 y값을 계산하여 비화학량론적 화학식을 설정한다. Fe 이온의 혼합원자가 상태, 산소 배위상태 및 공유결합성을 Mossbauer 분광분석 결과와 관련하여 논의한다. 전기전도도의 활성화 에너지는 -100 ~ $600^{\circ}C$ 의 온도범위와 대기압하에서 $\tau$값에 의존하였다. 시료의 Mossbauer 스펙트럼과 전기전도도를 비화학량론적 화학조성과 관련시켜 논의 하였다. A series of samples of solid solutions in the $Sr_xEu_{1-x}FeO_{3-y}(0.00{\leq}x{\leq}1.00)$ system has been prepared at $1200^{\circ}C$ under an atmospheric air pressure. The structures of solid solutions are studied by X-ray diffraction, thermal, Mohr salt, and Mossbauer spectroscopic analyses. Their physical properties are also discussed with the electrical conductivities. X-ray diffraction data for the compositions of x = 0.00, 0.25, and 1.00 are assigned to the orthorhombic and the compositions of x = 0.50 and 0.75 to the cubic systems. The lattice volume reduced to cubic cell increases with the x value. The mole ratio of $Fe^{4+}$ iometric chemical formulas of the system are formulated from the x, $\tau$, and y values. The mixed valency state of Fe ions, the oxygen coordination, and covalent bond character are discussed with the Mossbauer spectroscopic data. The activation enegy of the electrical conductivities depends on the $\tau$ value in the temperature range of -$100^{\circ}C$ to $600\circC$ under the air pressure. The Mossbauer spectrum and electrical conductivity of the solid solutions are discussed with nonstoichiometric chemical compositions.

日本語を第二言語として学習する学習者の立場から、それぞれ異なる表 現が韓国語では同じ意味に表現されているため、使用にあたって困難な場合が多い。本研究で取り上げている「腹が立つ」「頭に来る」「癪にさわる」という慣用表現は「怒り」という感情を表す類いであり、韓国語では「화(부아)가 나다」という類似した意味に表現されている。そこで、具体的な用例をもって「腹が立つ」「頭に来る」「癪にさわる」を考察した。その結果、「腹が立つ」「頭に来る」「癪にさわる」、3つとも「腹」「頭」「癪」という身体の部位を含んでおり、「怒り」という共通の意味特徴を表しており、程度副詞との呼応を成していることが分かった。これは「腹が立つ」「頭に来る」「癪にさわる」という慣用表現も一般的な感情動詞と同様に語彙性を持っていることを示唆していると言えよう。また、「腹が立つ」は、本人の反省を含め、自分自身の「怒り」、つまり自分自身を対象に表現できるのに対し、「頭に来る」「癪にさわる」は、自分自身を「怒り」の対象にすることができず、外部環境、原因による「怒り」という感情が発生していることが分かる。そして、程度副詞との呼応にも違いがあり、強度が高いものから強度が低い段階の程度副詞との呼応など、様々な様相を持っていることが考察できた。

TPororo the infant to "Pau president" is said to be derived from the loyalty of the children do not have enough degree. This toddlers The reason is simply to make immersive Formative amiable character that can not succeed alone. In this study, the time to create Pororo oil Oh, the development of psychological aspects considering the character"s formative By analyzing the behavior when watching animation, immersive toddlers May propose the necessary elements. In conclusion, look, baby animated character is given to the infant to the chemistry Indirect experience with friends and enhance children"s social and learning space which is second. Infants who can relate to peer relationships should be involved in spatial cognition concept and form of the immature infant nunnop In conformity to the expression of the molding element (color, shape, texture), such that engagement of the children improved. In other words, Pororo the infant at the time of the self-conscious being created to meet the needs of their social emotions gives Gave a sense of stability because of popular industry has seen box office success and her future babies future Animated characters are simply part of the exterior, rather than focus on their stage of cognitive development Considering the character design is expected to be needed.

학업성취도가 강좌만족도에 미치는 영향에 관한 연구 - 플립드 러닝을 적용한 디자인 전공수업을 중심으로 -
민지영 ( Min Ji Young ),정병국 ( Jeong Byoung Guk ) 한국상품문화디자인학회 2023 상품문화디자인학연구 Vol.72 No.-
팬데믹으로 인해 2020년부터 교육현장에서 학습자 중심의 교수방법인 플립드 러닝 수업은 확산되었다. 본 논문에서는 디자인 전공과목 중 일러스트레이션 수업에서 학업성취도가 강좌만족도에 미치는 영향에 관한 연구를 통해 플립드 러닝 활용수업의 효과성을 검증하고자 한다. 플립드 러닝에 대한 인식 조사를 위해 2022년도 2학기 수업을 수강한 49명과 그렇지 않은 비교집단 42명 수강자들을 대상으로 설문조사를 통해 아래와 같은 결과를 도출하였다. 첫째, 기술통계량 분석 결과, 플립드 러닝을 적용한 실험 집단이 비교집단에 비해 3가지 영역의 결과값이 전반적으로 높았으며, 그중 대인관계 영역의 결과값이 상당히 높게 나왔다. 둘째 상관분석 결과 비교집단에 비해 실험집단에서 학업성취도를 이루는 각 요소의 상관성이 높았다. 셋째, 다중회귀분석 결과, 비교 집단은 적절한 난이도 설정과 교수자의 열의적인 피드백이 강좌만족도에 영향을 미친다는 것을 알 수 있었다. 실험 집단은 퀴즈를 통한 복습방법이 강좌만족도에 많은 영향을 미친다는 것을 알 수 있었다. 본 연구를 통해 플립드 러닝에 대한 보다 다각적이고 깊이 있는 융합 연구가 촉진되어야 한다고 판단된다. Due to the pandemic, flipped learning classes, which are learner-centered teaching methods, have spread in the educational field since 2020. In this paper, we try to verify the effectiveness of classes using flipped learning through a study on the effect of academic achievement on course satisfaction in illustration classes among design major subjects. To investigate the perception of flipped learning, the following results were derived through a survey targeting 49 students who took classes in the second semester of 2022 and 42 students in a comparison group who did not. First, as a result of descriptive statistics analysis, the experimental group to which flipped learning was applied showed higher results in the three areas than the comparison group, and among them, the result values in the interpersonal relationship area were significantly higher. Second, as a result of the correlation analysis, the correlation of each element of academic achievement was higher in the experimental group than in the comparison group. Third, as a result of multiple regression analysis, it was found that the appropriate level of difficulty setting and the instructor's enthusiastic feedback in the comparison group had an impact on course satisfaction. In the experimental group, it was found that the review method through quizzes had a great influence on course satisfaction. Through this study, it is judged that more diversified and in-depth convergence research on flipped learning should be promoted.

색채 원리에 따른 교과서 시각적 주의에 관한 연구 : 아이트래킹 방법을 중심으로

Elementary Korean textbooks have long played a pivotal role in students basic education and learning Korean. Textbooks and pictures in textbooks are important visual information to help understand what is being learned, and the two different representational systems interact with each other. For the experimental sample, nine images were selected using the E.Imhof s color usage guidelines as an analysis framework, and textbook colors were analyzed using three knowledge representation methods of cognitive psychologist J.S.Bruner. For each type, the effect on students visual concentration was experimented by setting an interest factor (Grid AOI) using an eye tracker. The experiments were based on three preliminary experiments and the results of this study in the scan path and the heat map. This experiment proved that four to seven colors of characters, six to seven levels of color tone, two to three colors of background, and five to seven levels of color tone are suitable. This is a color principle that is adapted to the difficulty of the Korean language curriculum of the first semester of the 2015 revised textbook.
