This experiment, on the method of teaching English for left brain dominated engineering college students, was carried out through two groups, the experimental group which was composed of the engineering college students and the controlled group. The experimental group undertook dictogloss tasks in English class during the period of eight weeks from July to August, 2008. As a result, the effect of learning on experimental group showed significantly being high compared to that of the controlled group in the TOEIC test, an English ability test. This means that dictogloss is an effective learning activity which can be used in English class for left brain dominated engineering college students, and more improvement in English ability can be expected when appropriate levels and durations to learners are applied.

Until now, various educational budgets, facilities, and programs have been put into school education, but the results have not been clearly evaluated. This study presents a model to analyze the effectiveness of educational support for students in high schools across the country. In this model, we first use EM cluster analysis to make clusters with similar inputs for school operation, and then calculate the relative efficiency in each cluster by using Network DEA analysis. The Network DEA analysis has a two-stage structure where the first stage uses six inputs in terms of school infrastructure to generate outputs such as the number of academic persistence. In the Network DEA analysis, the second stage uses 10 inputs in terms of school programs to generate outputs such as the number of enrollees to higher learning and the number of employees and per capita usage of library as the connection variable. Based on the efficiency analysis results, Tier analysis is performed by applying the Euclidean distance to select targets for benchmarking. In this study, we applied the model to analyze the efficiency of educational support by collecting data regarding student education support in general and vocational high school nationwide. The stepwise benchmarking method proposed that the target be selected for efficiency improvement step by step, taking into account inefficient school elements to complement the problem of the choice of benchmarking targets. Based on this study, it is expected that schools with low efficiency of educational support for students will be used as basic data for stepwise benchmarking for efficient operation of educational support for students.

General Physics CAI Program was developed for university science and engineering student. The program was restricted in the field of mechanics and was mainly aimed for individual tutorial. This project was supported by Government. Department of Education, physics attending their general physics classes in university. The program was written in BASIC and constructed by frame, 4 professors and 6 graduate students were involved in the project. Summary of this study is as follows. 1. The theory of CAI was illuminated from a new point of view to enhance usefullness of CAI. Also the structure of frame type CAI was studied. 2. The program was developed as follows 1) The program consisted of main program, pretest routine, tutorial routine, final test routine, and several other routines for program control. Whole program was written in BASIC. 2) 20 problems for pretest, 90 problems and subsequent hints and solutions for tutorial, 20 problems for final test were developed. 3) According to student's pretest result, tutorial course was routed through several different courses which contain different number of problems 4) The expected rate of achievment for final test was set to 75%. 5) Data of students response to problems including number of tries and time used were recorded for the purpose of achievment analisys 3. 22 students went through whole course and the results were as follows. 1) Pretest marks were widly distributed from 20 points to 100. It means that achievement of high school physics course were not enough. 2) Throughout tutorial course, students who had got higher mark in pretest answered correctly in the first trial at a higher rate of 78 %. Overall rate of correct answer in the second trial was distributed appropriatly. 3) Average mark of final test was 78.8 points, rather a higher rate of achievement than expected. This means that the program was constructed well.

Excessive torsional behavior of asymmetric building structures is observed to be the main cause of the poor seismic performance. Concepts of current design provisions for torsion are based on the assumption that the strength of the lateral load resisting elements can be adjusted without changing their stiffness. This paper investigates inelastic torsional effects of multi-story high rise residential building in Korea on increase of strength demand and ductility of members using some methods published in literature. The methods analyze the reduction of strength and member ductility resulting from torsional mechanisms. This study shows that use of these concepts control inelastic torsion during preliminary seismic design of multi-story building of irregular plans.

In our research, we delved into the impact of video length assigned for pre-class assignments on students' level of engagement. What we discovered is that as the length of the video increases, student engagement tends to decrease and the time allocated for homework preparation does not significantly influence engagement, as many students tend to complete their assignments just before the due date. Interestingly, the well-known "6-minute rule" often advocated for online educational videos does not align with the dynamics of real university settings. Whether in traditional lecture-based classes or flipped learning environments, students exhibit a high degree of self-responsibility when it comes to video consumption. Our findings strongly suggest that, in the context of flipped learning, it is advisable to create videos that are shorter than 15 minutes in length.

The results of this study, suggest public communication to promote the use of radiation as follows: first, suitable information for the recipient's perception patterns should be provided, as there is a difference in risk perception and acceptance between the experts and the public. Thus, information on the necessity of nuclear power should be provided to the public, while information based on technical risks is provided by the experts. Second, since the levels of perception, knowledge, and attitudes increased highly for sectors which use radiation after the class, classes should be provided continuously to increase students' perception, knowledge, and attitude, which are all preemptive variables which induce positive behavioral changes. Third, since the seven sectors which use radiation are highly correlated, arguments for the necessity of other sectors should be based on the necessity of the medical sector.
