영화영어의 강점은 학습자에게 진정성 높은 표현을 제공하고, 정의적 측면에서도 긍정적인 기여를 한다는 것으로 알려져 있다. 그러나 표현의 언어적 측면을 강조하면, 학생들은 흥미를 잃기 쉽고, 영화의 흥미로운 내용을 강조하면, 영어 학습이 부족하다고 느끼는 경향이 있다. 따라서 교실 운영에서 학습자들의 흥미를 유지 시키며, 영화 속 표현들의 형태와 의미의 쌍을 균형 있게 다루는 방법을 모색하는 것이 필요하다. 이를 위해 세 명의 대학생을 대상으로 사례 연구를 진행하였다. 본 연구에서는 의미와 형태의 쌍을 강조하는 구문문법 개념을 사용한 영화영어 지도법을 제안하였다. 참여자들에게 영화 대본을 해석하게 한 후, 인상적인 표현을 선정하여 그 이유와 함께 보고서를 제출하게 하였고, 보고서 분석 결과 학습자들은 초기에 의미에 치우친 모습이 관찰되었으나, 연구자의 구문에 관한 연구자의 명시적 설명이 추가되면서, 점차 형태에도 관심을 보이는 결과를 보였다. 영화의 풍부한 줄거리, 등장 인물들의 관계, 대화공동체 요소 등을 활용하여, 표현의 형태에 따라 담고 있는 함축적 의미를 짝을 짓는 학습법은 영화영어 수업이 갖고 있는 고민에 대한 해결안을 제시할 것으로 기대한다. The purpose of this paper is twofold. First, it is to investigate whether L2 learners tend to study movie utterances in meaning-oriented ways, form-oriented ways, or both ways. Second, it is to suggest a method to deal with form and meaning in a balanced way by using the concept of construction grammar. To do this, a case study was administered with three advanced English major college students. The material was an American movie, Safe Haven. The participants were instructed eight times on the concept of construction, including a form-meaning pair. They were required to interpret the movie script. During the interpretation stage, the researcher provided an explicit explanation of the constructions. After each experiment, the participants were asked to write a report including impressive expressions they chose with reasons. The report analysis results showed that two of the three participants focused on the meaning of movie utterances, while the other one focused on both at first. As the experiments progressed, the participants gradually began to show slightly more interest in the form. The approach using the concept of construction grammar in English learning through movies is suggested as a method to deal with meaning and form in a balanced way.

The objective of this study was to investigate the effects of rootstock and night temperature on the growth and yield of grafted pepper (Capsicum annuum L.) in greenhouse. Four commercial pepper varieties, six commercial rootstocks, four breeding lines, and one eggplant rootstock were grown at three levels of night temperature (NT) (10, 15, and 20℃). At 10℃NT, the total dry weight was the greatest in 'Kataguruma' followed by 'Koregon PR-380' and 'PR-Power'. The dry weight of root at 10℃ NT was also the greatest in 'Kataguruma' followed by 'PR-Power'. RGRs of genotypes varied among the10, 15, and 20℃ NTs. They could be categorized into three types according to the response to NT. The RGRs of genotypes that belonged to type Ⅰ were reduced approximately 0.01 to 0.03 g·g<SUP>-1</SUP>·day<SUP>-1</SUP> as NT decreased. In type Ⅱ, they were similar between 15 and 20℃NT but rapidly decreased under 10℃NT, whereas they were stable irrespective of NT in type Ⅲ. 'Kataguruma' and 'Koregon PR-380' in type Ⅲ showed higher RGRs than other genotypes except 'Taibyo VF'. Cultivar 'Nokkwang' as scions was grafted onto rootstocks 'Kataguruma', 'Koregon PR-380', 'PR-power', and 'Tantan' selected from 14 genotypes. All growth parameters were greater in non-grafted seedlings. Among the grafted seedlings, the growth of peppers grafted onto 'Kataguruma' was better. The leaf area and dry weight of leaves were the smallest in the pepper seedlings grafted onto 'Koregon PR-380'. When these grafted peppers were cultivated at different NT conditions (8, 13, and 20℃) in greenhouse, low NT decreased the growth and yield of peppers. The growth and yield of grafted peppers were greater than those of non-grafted peppers irrespective of temperature. However, rootstocks with tolerance to low temperature didn't significantly improve the growth and productivity under low temperature condition, though the grafting did. Finally, we couldn't screen out any strong rootstock at low temperature condition for the better growth and productivity of pepper.

The sedimentary layer in a subducting slab consists of ca. 60 percent of water and ca. 40 percent of sediments, mainly composed of alumina and silica, especially in the form of hydrous clay minerals. The behavior of clay minerals under such water-rich subduction zone conditions is therefore important to understand the water transport into the deep Earth and related geochemical and geophysical phenomena. Here, we show sequential hydration and dehydration breakdown reactions of pyrophyllite (Al₂Si₄O10(OH)₂) under water saturated conditions along cold subduction geotherms down to the depth of mantle transition zone. At conditions corresponding to a depth of ca. 145 km (ca. 4.7 GPa and 435°C), we observe hydration breakdown of pyrophyllite to form a phase assemblage including a further hydrated mineral, gibbsite, which would remove ca. 14 volume % of water from the surroundings. As the pressure and temperature increase up to a depth of ca. 600 km (ca. 19 GPa and 700-900°C), we observe sequential dehydration breakdowns and formations of phase assemblages including diaspore, topaz, phase egg, and δ-AlOOH, which would release water into the region progressively. In addition, total energy calculations based on density functional theory showed an excellent agreement in terms of phase stability with our experiments, explaining the underlying mechanism for these sequential breakdown reactions. Our results thus provide a new mechanism of deep water cycle along the cold subduction interface that is potentially related to the origin of double seismic zone activities.
