  • National competitiveness is related directly to the strength of educational competitiveness of universities. Seoul National University (SNU) has been taking efforts to improve its competitiveness in University education in variety of ways and the classroom assessment is one key example of those. The current classroom assessment system practiced at universities is being used to evaluate courses and professors in charge by the university administration or evaluation committee. The classroom assessment system is not intended to put students and professors as the subject of the evaluation. In this case, the evaluation is intended wrongfully to rank the courses and evaluate professors' achievement by assigning grades on the lectures. Instead, a proper classroom assessment system should be targeted to improve the quality of lectures by encouraging communication among professor and students in the classroom. In this study, it was intended to investigate a suitable classroom assessment system to enhance the effectiveness of education, not to rank the courses and evaluate professors' achievement. For this purpose, research has been carried out to investigate opinions of professors at SNU on the criteria of classroom assessment and to analyze the criteria of classroom assessment at other domestic universities in Korea. The inquiries for feedback on the lecture by the student in the class was analyzed. The current classroom assessment system at SNU was reviewed and an improvement plan was devised to evaluate liberal art courses of engineering and science schools at SNU. In this research, the problems in the classroom assessment system was reviewed and improvement points were searched to utilize the classroom assessment system more effectively for the improvement of lecture quality.

  • The purpose of this study was to analyze the interactive patterns between teacher and students in middle school earthh science classroom, identify difference of discourse types between earthh science classes taught by majored and non-majored teacher, find the relationship between the discourse pattern and the type of teachers' questions. For that purpose, the participants in this study included four teachers and their students of three middle schools in Seoul. The data consisted of two parts. First, we categorized interaction between teacher and students into the types of discourses by the use of Mortimer and Scott's analytical framework(2003). Second, we classified teachers' questions into four different types of question based on MNeill & Pimentel's classification scheme(2009) to examine for the relationship between the discourse pattern and the type of teachers' questions. As a result, all teachers used interactive/authoritative discourse most in middle school earth science class. Therefore, there was more authoritative discourse to non-majored teacher in comparison with majored teacher. And study demonstrated that the discourse pattern was more related to feedback about student's response rather than the type of teachers' question. In other words, the dialogic discourse showed up more frequently when the teacher used delayed feedback with positive and accepting attitude.

  • The purpose of this study was to develop a digital textbook on 'structure and contraction mechanism of skeletal muscle' with the learning model for biomimicry-based convergence. The unit of 'structure and contraction mechanism of skeletal muscle' is a part of Life Science I in high school. The convergence learning model was designed with three phases of biomimicry-based convergence (Exploration-Design-Implementation) including 3D modeling & printing. The developed digital textbook was composed of 8 sessions which contains the following learning contents : Exploration of skeletal muscle, creative designing of skeletal muscle using sketch application and 3D modeling, convergent implementing of the designed using 3D printing, exploration of muscle contraction, creative designing of muscle contraction using sketch application and 3D modeling, and convergent implementing of the designed using 3D printing. Each session is also involved in the contents of gallery widgets, media widgets, keynote widgets, sketch widgets, the cloud, polling widgets, and review widgets for interactive and mobile learning. After administering the developed digital textbook to 20 high school students, it was shown a positive effectiveness on life science learning for high school students. Moreover, the digital textbook was evaluated as to promote student's abilities on creative designs and implementation related to biomimicry-based convergence. The digital textbook was also shown a favorable response on students' interest and self-directed learning on life science.

  • A Discourse Analysis tool has been developed and has been applied in the cooperative group inquiry activities in order to derive the characteristics of elementary gifted students in science. We recorded and videotaped the whole group problem-solving processes where 4 elementary students worked together to solve given problems as a group for one year in a gifted education center attached to a university in Seoul. We analyzed recorded discourses using systemic functional linguistics with a focus on the structure of information and topic. The discourse analysis tool was developed with the cooperation of science education and gifted education experts. In discourse analysis, we focused on meaning development processes rather than grammatical analysis. Through application of newly developed discourse analysis tool, we confirmed that the tool is useful in understanding the characteristics of science-gifted elementary students. We also founded that the interaction between students has significant effects on problem-solving processes by comparing two students who showed contradictory features in the share of dialogue. In addition, the result suggested that we need to provide students with proper training for ways to communicate with others for effective science-gifted instruction.

  • Interactive electronic technical manual(IETM) for construction projects means an electronic tool that regulations and specifications related to construction method or maintenance process ale described by electronic book type. It has a meaning of integrated information system that includes virtual reality(VR), 3D animation and image contents for representing real construction information so that user can easily understand the construction situation and maintenance process. The basic information and technical manuals of construction facilities are being written as paper documents in our construction industry. As the result, the information management in the maintenance phase of construction projects is inefficient, and maintenance cost is being increased. This study attempts to improve the lack of understanding about construction IETM through the analysis of necessity and unique function of construction IETM comparing with the IETMS in other industry, Finally, this study shows a scenario of construction IErM for mitigating natural disaster of construction facilities to verify applicability of IETM.

  • The streams evolve to diverse forms influenced by various factors such as rock resistance tectonic process, sediments and discharge. This study focuses on erosion resistance of rocks among these factors. The morphology of plane and longitudinal profile has been analysed in upper and lower reach of 6 streams using GIS; Yeoryong-cheon, Heungjeong-cheon, Duhak-cheon, Daehwa-cheon, Namcheon-cheon, Guryong-cheon, having distinct bedrock types between upper and lower reach. While the basins of granite have gentle slope, low concavity and wide valley area, those of gneiss form steep slope, high concavity and narrow valley area. However, the basins of sedimentary rock make steep slope and high relief in main channel, the other features show some differences in each stream. Among the various morphological features, the indices on slope and concavity of main channel, drainage density, ratio of valley area, average slope and average relief of the basin which have clear differences between rocks in upper and lower reach are calculated to interpret the erosion resistance of rocks in upper and lower reach. As a result, the upper reaches composed of gneiss have the highest erosion resistance, sedimentary rocks in upper and lower reaches show moderate resistance, and granite reaches generally have the lowest resistance except the upper reaches bordered by sedimentary rock.

  • The author conducted a records research named 'daily life and records.' The purpose of the research was to find an archive, if possible, that would be effective in promoting exchange and cooperation among people in their daily lives, and to distinguish what type of archive it would be, as well as how to let it naturally take place in their ordinary lives. For 4 months (August-December 2019) with 100 college students in their 20s, trial and error were repeated. There was no separate laboratory for the research, and it used regular school hours at universities. Although it is true that there was a control through power by the college system, the plot was centered on the sunshine policy. To human being there is a voluntary and positive attitude. If anyone begins to take this attitude it is difficult to stop such action. Through emotional support, this voluntary action was encouraged to take root. The experiment was an attempt to doubt the obvious, and to search for something new. From afar, this may seem irrelevant to archives. However, for the author who is a professional archivist, it was a time of records through control by Records principles. By organizing into a form of story, its archival implications are observed.

  • It is settled in the economic arena that electronic commerce which used the Internet is new recently by explosive increase of the rapid development and Internet use of the information and communication technology. The problem that is legitimate at a point called the business of the form that the electronic transactions to set together if I drift are new of the times is the situation caused a lot. However, the use custom of construction and electronic transactions of the maintenance that is the legislation thief who can do rules of electronic transactions is the fact that it was not able to be still established It may not be just applied to the Internet electronic transactions that an exchange promise between our characters does against unspecified number of the general public person in the property even if I say that the conclusion of the purchase agreement is concluded in Internet electronic transactions by EDI method. That can have the approval of contract in the main legal problem of such an Internet electronic transactions contract. We civil law sorts it by a contract between the talks characters and a contract between the remote area people and all the adopted children are equal and must decide the formation of contract time in a principle of Empfangstheorie because it may be said that the rule of the civil law that it be heated and decides to be able to be available is irrational.

  • Concerning the political situations of Korea, after the coming of MB Administration the blockades between South and North has been deepened. Because of stopping of the tourism of Diamond Mountain, the Cheonan ship accidents and the ** bombardment of Yeonpyung island, the situation of confrontation of South and North is enlarged. After the death of Kim Jong-il, on 17 Dec. 2011, the new situations are opened in North Korea(NK). On the basis of economic cooperation between South and North, various logistical cooperation of South and North has been progressed. On November of 2002, the 1st Shipping Cooperation Meeting of South and North, which may be a basis of Shipping Agreement has been discussed. And the railway between South and North has been connected. This study, screening the change of South and North conditions, analyzed the tasks and current conditions of South and North logistics based on economic cooperation, with the previous researches and data of South and North Korea. And it grouped and suggested future development directions and practical agenda, after considering the recent changes. Furthermore it proposed the medium-long term logistical system of Korea peninsula and future strategies and vision. To solve the confrontation situations the role of South Korea is more important.
