Narratively I have described interactions between two teachers performing an introduction to the engineering class with various situations such as place, teacher, student and subject. I have specifically illuminated a three-dimensional narrative inquiry space embracing the culture of the university, the college of engineering and the ABEEK(Accreditation Board of Engineering Education of Korea)program. The result of the study is as follows: First, in order to stimulate the students' motivation, the teachers have to make not only their class PowerPoint slides match the size of the classroom, but the content of the slides must be condensed with core concepts. They also should utilized some video clips to empower students' interest in the subject within their classrooms. Second, the teachers should do various class activities in the classroom. Instead of spending most of the class time with his/her explanation, it would be advantageous for the teachers to allow the students to perform a task in class. Third, the teachers should ask their students about assignments which are helping students' understanding of the subject and planning of their future. Lastly, the teachers need to design the mid-term and the final tests inducing the students' motivation. Those tests also must test students' creativity and insight of the subject. Thus, the test should consist of an interpretive exercise and an essay type of item thus reducing the multiple choice types of items. There are several limitations to the study. First it is difficult to generalize what we found here because it is a case study. Second, we could not study in depth the effect of the interaction between the two teachers who were performing the introduction to the engineering course during the academic semester. Third, this study just probed into the difficulties of teaching the course. Hence, we have to understand more by focusing on each issue such as adapting to a new learning environment as a student from abroad, a practical experience boosting the students' interest in the introduction to the engineering course, also a practical experience on process based learning-versus result based learning, and an effective management of the student team presentation etc.

Within regional and municipal planning we are using several levels or types of EIA in the city of Dresden. Some of these types, practical aspects and some experiences of our work will be presented in this contribution. Firstly I may introduce you to some general conditions for your better understanding of our principles of work. Surely you know about. the destruction of the political and economical structures in Eastern Germany since 1989. Until today our not quite simple task is to build up new ones. At the same time people were in great expectation of freedom and high standard of living as soon as possible. Economical difficulties increased in association with the breakdown of the market in Eastern Europe. How to rebuild industrial estatements and how to renew the traffic systems? We had to find answers to all these complex question. Should we only repair the former damages or could we reach a really environmental sound production for the future? The demand for a rapid economic growth is an incredible challenge for the application of new environmental ideas. I am truly not sure whether you know the city of Dresden or not. So I would like to give you a short introduction. Dresden is situated in a valley shaped by the river Elbe. There live about 500,000 people. Dresden has a great reputation for arts and sciences. Its also well know as a town of high technology industries such as electronics and optics. We restored the power plant and therefore we don't need any atomic power plants actually we haven't got one. Since 1990 there were founded many official agencies in Dresden because it is the capatal of Saxony. Considering nature and environment we there is a large forest area called "Dresdner Heide". The river Elbe and the meadows are situated on both sides of the river. There are a lot of green and free places in the city area too. Furtheron there is something unusual for a large city: about 50% of the drinking water resources mostly take place within the city itself. The origin is the ground water as well as water from the river Elbe after filtration of course.

Globally SW education is becoming increasingly important, and the government is preparing for this trend as a mandatory implementation of SW education in the 2015 revised curriculum. However, because the 17 hours of annual education offered in the course of Practical Arts cannot have great educational effects, this study attempted to develop a robot-based SW education program related to other regular subjects. Also in order to verify the effects of the program related to future competencies, problem solving ability and communication ability were selected as key factors. The paired t-test was conducted to examine whether there was a significant difference between pretest and posttest results. As a result, it was verified that the subject-related SW education program using robots was effective in improving students' problem-solving ability and communication ability. In addition, after the program was completed a survey was conducted, and it was possible to confirm that students could have positive perception on SW education.

Patterns in clothing symbolize some specific meaning that differs across cultures and religions, although patterns have been mostly used to realize human desires to overcome natural hazards in every culture or religion. This research aims to compare animal patterns of Korea (Confucian/Buddhism culture) with those of Byzantine (Christian culture), based upon a research method of literature survey. It is found through the research that both cultures used common patterns, such as dragon, butterfly, bat, honeybee, peacock, fish, and chicken. In the case of dragon patterns, Korea used it to symbolize emperor, dignity, or authority, while Byzantine used it for devil. Bat patterns had different symbolic meanings in both cultures: they mean happiness, longevity, prosperity or many off-springs in Korea while they mean misfortune or unhappiness in Byzantine. On the other hand, the rest of animal patterns, including butterfly, honeybee, peacock, chicken, had quite a similar symbolic meaning. Butterfly means change of life or beginning of new life in Korea, whereas it means resurrection in Byzantine. Honeybee symbolizes diligence, order, and cooperation. Many animal patterns were used in both cultures at the same time. Another difference can be found in terms of the kind of animals; for example, Korea used wild goose, pheasant, giraffe, deer, mandarin duck & turtle, while Byzantine used eagle, snake, pigeon. Of course, each and every animal has its own meaning, mostly positive. Except dragons and bats, both cultures have a similar meaning in most of animal patterns. Generally speaking, Korea used imaginary animals to pray for human happiness, but Byzantine used real animals to pray for resurrections.

The Direct Instruction (DI) was applied to the learning-disabled in the basic engineering education (especially, physics education). The DI is specified as an educational method in which the instructor strongly controls during the whole process of the entire course. The tests of understanding, reasoning, memory, and problem-solving speed showed that 20 students (20%) out of random 100 students are learning-disabled. The average points of mid-term and final exams were 53.7% and 61.0% respectively for a certain 41-students class. However, in this class, for the lower point students who obtained less than 50% points, the average points of mid-term and final exams were 29.8% and 28.2% respectively, which showed decreased. From this lower point group, the 8 students (20% students of 41 students) were selected as the learning-disabled. With additional DI studies provided, the average points of mid-term and final exams for the learning-disabled were 18.9% and 25.5% respectively, which showed 6.6% increase that means the DI for the learning-disabled was effective.

In this paper, as a liberal arts course for non-majors, we proposed a supervised learning artificial neural network parameter optimization method and a basic education method for activation function to design a basic artificial neural network subject curriculum. For this, a method of finding a parameter optimization solution in a spreadsheet without programming was applied. Through this training method, you can focus on the basic principles of artificial neural network operation and implementation. And, it is possible to increase the interest and educational effect of non-majors through the visualized data of the spreadsheet. The proposed contents consisted of artificial neurons with sigmoid and ReLU activation functions, supervised learning data generation, supervised learning artificial neural network configuration and parameter optimization, supervised learning artificial neural network implementation and performance analysis using spreadsheets, and education satisfaction analysis. In this paper, considering the optimization of negative parameters for the sigmoid neural network and the ReLU neuron artificial neural network, we propose a training method for the four performance analysis results on the parameter optimization of the artificial neural network, and conduct a training satisfaction analysis.

This study was attempted to examine our perceptions, which are required as our society prepares for a multicultural society, targeting college students who are in charge of the future of a multicultural society, and to propose specific ways of changing what and how. A survey was conducted on college students taking the same liberal arts course four times each semester in 2018 and 2019, and a total of 299 survey data were used to analyze the results, excluding 6 insufficient surveys. As a result of the analysis, it was found that migrants had a negative image when they were younger or had no foreign experience. Regarding the factors of cognition of migrants, social distancing and cognitive flexibility were found to be more intimate with migrants when they were older, but were more concerned about social issues. Finally, in terms of the conditions for accreditation of migrants to Koreans, it can be seen that social welfare majors agree with the conditions for recognizing migrants as Koreans in much more categories than those with mixed majors. Based on these results, several practical methods that can be applied to college students who need to prepare to lead a multicultural society were proposed.

Traditional speech training in acting education focused on the technical aspects of expressing the lines such as finding long/short syllables in the word, exercising articulation of consonants and vowels, and practicing diction etc. There was a limit on this education to transform written words to vivid verbal words. The lines become live when the actor sees the concrete mental images hidden in the words while speaking the lines. I will bring the knowledge of cognitive brain science and NLP(Neural Linguistic Programming) to investigate what mental images are and why mental images are fundamental elements of thought and emotion. In addition to that, I will examine how the muscles of the body react in the process of visualization of delicate mental images (subordinate form) and how to use the responsive muscles to express speaking materials such as intensity, pause, pitch, intonation etc. Conclusion, I will enumerate the obstacles encountered by actors in the course of practicing mental images, and suggest 'activation of breathing' as a thesis of the follow-up paper to eliminate those obstacles. This process, I intend to make mental images to be the concrete and practical information that can be applied to speak the dialogue in the play.

In this paper, as a liberal arts course for non-major students, a case study of recurrent neural network SW practice, which is essential for designing a basic recurrent neural network subject curriculum, was developed. The developed SW practice case focused on understanding the operation principle of the recurrent neural network, and used a spreadsheet to check the entire visualized operation process. The developed recurrent neural network practice case consisted of creating supervised text completion training data, implementing the input layer, hidden layer, state layer (context node), and output layer in sequence, and testing the performance of the recurrent neural network on text data. The recurrent neural network practice case developed in this paper automatically completes words with various numbers of characters. Using the proposed recurrent neural network practice case, it is possible to create an artificial intelligence SW practice case that automatically completes by expanding the maximum number of characters constituting Korean or English words in various ways. Therefore, it can be said that the utilization of this case of basic practice of recurrent neural network is high.

The purpose of this study is to find out the factors of the students' achievement on the computer training courses which are based on computer practice. In order to improve the academic achievement of the students, it is necessary to analyze the factors affecting academic achievement and apply the results of the analysis to education. In particular, it is necessary to study for finding out factors of the academic achievement in practical computer training courses, because these courses are different from other courses focusing on the theory. In this study, in order to find out the factors, the logistic regression analysis and the decision tree analysis which is the field of data mining were peformed. For the experimental data, the test results of the MOS certification of the S university in seoul were used. Through logistic regression analysis it is found that the factors of the professors, class size, lecture time, group(lecture period) are important in order. Through decision tree analysis of data mining, it is found that there are some additional factors ; entrance year, whether the course is retaken, and the classroom environment. and these various factors effect the academic achievement compositively as identified through the model tree. The tree model was presented as a result of the analysis, and the importance of the factors is expressed numerically from multiple tree models by using the proposed mathematical formula.
