The engineering industry is the representative knowledge-based industry of a nation which promotes the high technology of all industries of the nation, and plays an important function and role in the entire economy of a nation, and is also the representative industry by which the national technology competitiveness be measured. Our engineering technology capability still accounts for only 80% ~ 90% of that of advanced countries.

Since the engineering industry is knowledge-based and engineering technology capability highly depends on engineers with experiences and know-how, nurturing good engineers is a prerequisite for the improvement of engineering technology.

However, given our system of local engineer manpower management where an engineer's position determines his ability as well as his salary, it is often the case that he automatically promotes to a higher level or is treated as a special engineer in the current structure of the system. In a nutshell, although it requires an engineer specialized technology and accumulated expertise, the local system has its structural limitation.

The education of engineers is mostly done collectively, but the attendance of the members at collective education and training programs is slim due to the difficult conditions of the local engineering industry and their frequent travels. In addition, this type of education has a low effect on encouraging them to develop themselves voluntarily. In order to facilitate self-learning to improve an engineer's ability, an environment needs to be created for continuous and voluntary self-development by means of a self-learning modular system, which needs to be developed.

This study is aimed at presenting the priority of the development of student-centered modular learning subjects and designing a learning course needed in the process of engineers' career development given the needs of self-learning of engineers, the internationalization trend of engineering industry and the diversification of engineering technology.

To that end, this study reached the following conclusions on the basis of the analysis of local and overseas self-learning modular systems, the self-learning needs of local engineers and experts' opinions.
 
Production of common subjects in the specialization field
Production of common subjects by field
Production of the priority in the development of subjects  
Learning course design  
An effective operation method of self-learning modular system  
Expected Effects  
The foundation for the career development of engineers by modularizing the subjects which are essentially needed for the technology improvement of engineers and codifying them by subject so that engineers can advance from the beginning level to the intermediate level and then to the high level or the special level.
The foundation for the self-learning system, which does not give time and space restrictions to engineers, should be offered let alone the current collective education system in which it is difficult for engineers to attend education programs due to their frequent travels and the insufficient financial conditions of engineering businesses.
It is also expected that the favorable circumstances for engineers to learn by themselves will increase the engineers' attendance at education programs, and at the same time produce positive education effects. Namely, self-learning modular system will make it possible for engineers to self-learn through the modular learning centered on hands-on technologies and improve the specialization and creativity of engineers. Moreover, it can meet various needs for various levels and abilities of learners. Therefore, the new system will raise the adaptability of engineers to the job by providing various level study materials to engineers.
At the same time, it will be possible to train superior engineers through life learning, so that the international competitiveness of local engineering businesses can increase.
