This study is a case study on investigating students' learning behavior in the online English reading class of an on-off course. For this purpose, a survey was conducted on a total of 77 students from an English listening and reading course and phone interview with 5 students was implemented. The findings revealed that regularity of learning interval and learning sequence need to be improved through student management in order to increase the effect of online learning. In case of lecture watching, the students are good at utilizing the strengths of taped lecture, such as using pause and repeating watching. However, more research need to be done on how to develop online lecture to enhance students' understanding of the lecture. Regarding the offline review quiz that is supposed to stimulate students into their more positive watching of the lecture, it is suggested that a few of its related elements such as the online learning period and the number of quiz questions be corrected for its better effect.

The ICELT(In-Service Certificate in English Language Teaching) is a highly practical course-based English teacher education program which integrates classroom teaching and off-site teacher training. This case study analyzes the three-year implementation of the ICELT program in Korea and discusses its effects and the implications for improving the inservice English teacher education system. It has been found that the course participants were satisfied with the quality of its execution, thinking that it contributed to their professional development in the areas of teaching practice, methodology and language competence. The study has identified several success factors as shared program goals among the course participants, including systematic selection of course participants, well-qualified tutors and the proper provision of resources including syllabus, teaching materials and course assessment system. Nonetheless, it has been suggested that attention needs to be paid to generalized application of the ICELT for English teacher education due to the limitations such as the heavy workload caused by the program, lack of course participants' collaboration with other teachers at their schools and tutors' poor understanding of the Korean education context. Bearing this in mind, the implications for improving the inservice English teacher education system in Korea have been discussed. Finally, further studies have been suggested, which are concerned with in-depth investigation in exploring the division of roles between native English speaking tutors and Korean ones and the impact of the program on the sustainability of course participants' professional development and the impact on schools.

We introduce an introductory engineering education course for engineering majors and non-engineering majors. This course does not require any previous knowledge and experience on engineering. It requires strong curiosities and imaginations on current and future society we live in, where technology is inseparable ingredient. Course encourages attendees to explore fundamental issues of engineering: what is proper technology and what are proper ways of exercising engineering, issues dealt in soft engineering. Since course topics cover many aspects of technology, traditional learning methods fail to be successful and efficient. Various efficient learning methods have been proposed and implemented. We utilize various interactive tangible media, which include simulated thought experiments and physical media experiences. About 20 episodes in short film format are produced based on scenario written according to related issues selected. Physical media like interactive robots are introduced for attendees' stimulated experiences. We summarize our exciting experiments on interactive teaching experiences at Pusan National University which include on/off-line interactions, assignments, projects, and evaluations.

KARI (Korea Aerospace Research Institute) is going to launch a Communication, Ocean and Meteorological Satellite (COMS) at summer of 2009. It will be first thing to be developed for a geostationary satellite through domestic technology. Of course, KARI has performed this development program with EADS Astrium in France since 2005. COMS has the non-symmetric configuration that the solar array is only attached on the south panel. Due to the configuration, momentum of satellite will be rapidly accumulated induced by solar pressure and then 3 wheels of large momentum are located on roll-yaw plane for attitude control. Therefore, to prevent the saturation of wheel momentum, wheel off-loading will be performed two times per day during 10 minutes for each one. At the moment, translation movement on 3-axes direction appears because of using thrusters. In this paper, strategy of the wheel off-loading and triaxiality which is the translation effect on 3-axes are introduced. Consequently, the result of optimized triaxiality considering the wheel off-loading strategy is summarized.

Boil-off loss ratio is one of the most important economic traits to be considered during the course of silkworm breeding. The boil-off loss ratio varies among the breeds and seasons. The present study was undertaken with 5 oval and 5 peanut breeds and twenty five hybrids involving these parents to select the promising hybrids with desired boil-off loss ratio. Accordingly, studies were undertaken to estimate the heterosis and heterobeltiosis. It was observed that majority of the hybrids revealed negative heterosis for boil-off loss ratio which is desirable. Based on the heterosis and heterobeltiosis, among all the hybrids, the hybrid APBRO5 ${\times}$ APBRD5 exhibited highest negative heterosis for boil-off loss ratio and also exhibited highest EI value (64.5) for the quantitative and qualitative traits. Based on the hybrids performance, boil-off loss ratio, heterosis and heterobeltiosis and evaluation index, the hybrids viz. APBRO5 ${\times}$ APBRD5, APBRO1 ${\times}$ APBRD1 and APBRO3 ${\times}$ APBRD4 were identified for commercial exploitation.

It is necessary for the engineering students to have a business mind for the contemporary world of business. We developed a focused management education program for engineering students in C-University. The management education program consists of both on-line and off-line learning. ABEEK requires 720 engineering students of C-University must take basic management course. The on-line lecture was developed to overcome the shortage of qualified lecturers in business school. On-line lecture made by the business school faculty(not lecturers) can evenly provide high-quality content for every engineering students. In addition, the program is designed that off-line classes administered by lecturers complements the limitations of on-line lecture. Having in mind that selected senior engineering students understand technology and basic business, we developed an advanced course focusing on technology-oriented venture businesses. On and off-line blended learning and two-step approach of management education for engineering students of C-University may shed some light on other engineering schools in similar situation.
