The purpose of this study is to suggest the effects of schema activation on reading comprehension. The subject of a sample survey was a 36 student experimental group and a 32 student control group, total 68 students at third grade class of C Middle School in Gwangju. Students ability to read English in the two groups were almost the same through, which was shown by pre-test administered before the beginning of the experiment. As a pre-reading activity, the experimental group was showed the pictures and vocabularies related to the text before reading. The other control group did Grammar Translation Method about text. The data needed for this study was obtained by the questionnaires with 25 questions about the English reading. The data analyzing method was t-test through the statistics program SPSS 12.0. The result of this study is as follows : First, the experimental group got a more meaningful score than the control group at the test. Second, pre-reading activities for providing prior knowledge of the text were affected by the student's English proficiency, peculiarly more effective on low level student than advanced level. Studying English reading through schema activation led the students to be present in classes with interests, so the experimental group showed more academic accomplishments than the control group.

The Dokdo volcano in the south-central part of the East Sea is classified into 8 rock units. The units and sequence suggest that the Dok Island forms a small stratovolcano constructed from at least 3 times eruption cycles above the sea level and proceeded with transformation of a few different eruption styles during each cycle. Reconstruction of the volcanic form, from the geologic structures and spatial lithofacies changes, suggests that the island is remnants of the southwestern caldera rim of the stratovolcano whose central part lies several hundred meters to the northeast. The subaqueous volcano shows abig guyot, which looks like a shield volcano, that represents gentle slope at 90-175 m deep and relatively steep one in 200∼2,000m, and 25∼30km wise base on sea floor. Therefore the total Dokdo volcano represents a multiple volcano that stratovolcano with small caldera overlies the big guyot.

The foundation courses of industrial design from Bauhaus to today is, a delivery room of modern industrial design, played an essential role of the image formation in the current German design. In the foundation courses of industrial design that is required in our society, not only the concept gestalt should be understood, approached to industrial design through the integrated meaning of science and culture. In this paper, the historical establishment background of gestalt universities that contributed enormously to the development of German industrial design was analyzed, and then tried to understand the fundamentals of German design education. Also the results of the foundation courses at Bauhaus, Vim university and current German gestalt universities are compared to the products, which illustrates a typical German Image. With this comparison, the importance of the role of the basic design education was recognized, and using the results the necessary direction of the foundation courses in Korean industrial design was presented.

The purpose of this study is to explore secondary school teachers' perceptions of student evaluations, focusing especially on students' performance in the classroom. The study selected Germany as a representative country where teachers' performance evaluation strongly affects students' school pathways. The researchers selected 4 English teachers and conducted in-depth interviews with them. The results indicated that German English teachers perceived students' performance as an individual evaluation and provided each student with oriented learning materials and evaluation results. The second, they used formative evaluations to confirm and motivate their students' learning process as well as peer assessments. The third, the German English teachers showed strong empowerment in the evaluation process. The fourth, they motivated to participation in-class activities teacher through performance evaluation considering fairness.

In an effort to explore the effects of Youtube video-watching activities on Korean college students' English reading comprehension skills, 148 undergraduate students who enrolled in a General English class at a university in Korea participated in the present study. Participants were randomly classified into four groups - three experimental groups and one control group - according to when they watch videos: before class (n = 33), during class (n = 42), after class (n = 36), and none (n = 37). Over 16 weeks, the three experimental groups engaged in Youtube video-watching activities for about 10 minutes before, during, and after the class, while the control group did not. Pre- and post-tests were administered to confirm the effects of the use of Youtube videos on improving English reading comprehension skills. To compare the improvement between groups, a one-way ANOVA was also run. Major findings are as follows: First, participants in all the three experimental groups significantly improved their English reading comprehension skills, indicating the beneficial effects of Youtube video-watching activities. However, there was no statistically significant difference in the mean improvement between the groups. Based on this, limitations and suggestions for the future research are discussed at the end.

The efficacy of spinetoram sprayed from an unmanned helicopter to control two insect vectors of pine wood nematodes, Monochamus alternatus and M. saltuarius was assessed. By using a ULV (Ultra Low Volume) sprayer, the mortality rates of phenthoate, bifenthrin, etofenprox, and diflubenzuron, which are registered for use against coleopteran insects, indoxacarb and spinetoram, which are registered for use against lepidopteran insects, were evaluated for efficacy as aerial spraying agents. The ULV test, using 33- and 55-fold dilutions of phenthoate, bifenthrin, indoxacarb, and spinetoram demonstrated a 100% insect mortality rate upon contact and feeding mortality on the third day after treatment, while etofenprox and diflubenzuron exhibited a slightly lower mortality rate than the remaining compounds. Consequently, spinetoram was selected as a candidate pesticide for aerial spraying and its efficacy to control the insect vectors was assessed. The x 33 dilution of spinetoram resulted in a 98.6-100% control efficacy against two insect vectors. However, risk assessment for bees following aerial spraying will be necessary before applying the pesticide to control insect vectors.
