In this paper, the author researched to enhance course outcomes while increasing the interest in engineering design through the 'Introduction to Engineering Design Course'. Deviating from the current practice of engaging in content-oriented lectures, the redesign of the weekly lecture has been conducted with a focus on learning achievement in order to enhance design competency, teamwork and communication skills, which are the goals of the PO3, PO6 and PO7, respectively. Moreover, assessment tools have been developed according to learning achievement, and rubrics, the measurement criteria, have been defined according to the respective assessment tools, along with course goals for learning achievement and results analysis. To enhance course learning achievement, as well as to induce interest in and satisfaction with the 'Introduction to Engineering Design Course', a design project utilizing a Boe-Bot robot has been carried out. An evaluation on learning achievement and lecture has identified an increase in learning achievement and interest in design in comparison with that of previous lectures.

The shipbuilding process is changing due to changes in the development environment and technological requirements for military ships. This would also hold true for a submarine, because its shipbuilding process includes complicated design and construction conditions. System improvement efforts for the design and construction of military ships have continued with the goal of overcoming these conditions. At present, the Korea Navy is developing a 3,000 ton-class Korean type submarine, and its design is progressing by the introduction of a full 3D-ship CAD system. Although the 3D modeling system was introduced for effective design realization through the introduction of collaborative design and active utilization of M&S (modeling and simulation), the introduction effects are not yet generally obvious, according to the characteristics of ship design. The present paper discusses the collaborative environment for developing a submarine to enhance this. This paper proposes the architecture and data structure of a system for realizing collaborative design and discusses a case system developed on the basis of this.

In this paper the author proposes a case study of a freshmen introduction to engineering design course ing LEGO Mindstorm NXT and analyzes the survey results of the course. The diffilculties are that this course should provide various aspects of design experiences to the students while not requiring the major knowledge and skills and it should attract the students to the engineering major. According to our case study LEGO mindstorm can be a good solution to this problem. The design experience with LEGO Mindstorm NXT provides students with various aspects of design experiences including defining problem, finding constraints and functions, exploring design space, and performing preliminary design, as well as fun. This paper also provides a project list that can be used for freshmen design experience including soccer game robots, line tracer, and vacuum cleaner etc.

This study aims to study IFD based IFC application, and API technology were examined for extending $IFC2{\times}4$ information by using IFD libraries. According to this, information exchange scenarios for Open BIM were established with IFD application. And necessary standard elements for introduction of IFD were introduced and the templates of object and property information were suggested for realization.

Performance-based design concepts require the next generation of codes. To implement the main concepts several design methodologies have been proposed. This paper reviews the framework of Korea Seismic Code and shows necessary modification for adoption of appropriate design methods. The selection of design earthquake levels with the introduction of risk factor is discussed for proper risk levels for all earthquake hazards. Displacement-based design, energy-based design, comprehensive design, and force-strength design methods are reviewed as one of possible next generation design methods. This paper proposes the direction of reconstruction for design earthquake levels with performance matrix, introduction of new design methods, and emphasis on non- structural components.
