In this paper, we propose hardware prefetch mechanism with an efficient cache replacement policy by giving priority to the trigger block in which a spatial region and producing a spatial region by using the displacement field. It could be taken into account the sequence of the program since a history is based on the trigger block of history record, and it could be quickly prefetching the instructions or data address by adding a stored value to the trigger address and displacement field since a history is stored as a displacement value. Also, we proposed a method of replacing at random by the cache replacement policy from the low priority block when the cache area is full after giving priority to the trigger block. We analyzed using the memory simulator program gem5 and PARSEC benchmark to assess the performance of the hardware prefetcher. As a result, compared to the existing hardware prefecture to generate the spatial region using a bit vector, L1 data cache miss rate was reduced about 44.5% on average and an average of 26.1% of L1 instruction misses occur. In addition, IPC (Instruction Per Cycle) showed an improvement of about 23.7% on average.

We investigated the conceptual and methodological characteristics of self-study as an innovational way with reflective research methods and explored the possibility of application of self-study in the field of science education by reviewing previous researches done in foreign countries. The results show that Self-study in education means the study of self, self-practice, self-thought, and so on in the teaching and learning context. It is a kind of new research method to pursue the improvement of teaching and learning practice with integrated perspectives on the context of instruction, identities of members, their beliefs and values, innovation agenda for better education, etc. This can be attained by collective and critical reflection in doing research. Most previous articles on the methodology of self-study suggested that the self-study should be more than just daily journals written only by her/him self. To do self-study in the academic way, they requested interaction with critical and cooperative colleagues, multiple but strict qualitative research methods, and participants' efforts for making better practice in instruction. Similar features to the above are found in the previous 14 self-study papers related to science education done in foreign countries. Based on the results, we concluded that self-study could be applied usefully into the field of science education in Korea. This paper could contribute to stimulation in the innovation of science instruction in a more practical way by increasing the attention to self-study and provoking its practice in Korea.

Web Based Instruction has its theoretical background in constructivism paradigm of education. According to social changes called information era and thanks to the sophisticated internet mechanism the constructivism in education has been dominant paradigm. In this paradigm information and knowledge are not merely given by a instructor facing the loaners. This system of instruction has n almost every field of discipline introduced. This article aims to examine how far WBI and constructivism are applicable for design education. Richard Branchia predicted that the learner oriented instruction method would become the dominant education system. He stressed an interactivity of the teacher and students. Upon this can the applicability of WBI for design education be affirmed. Furthermore, there is a dozen of successful cases like www.cyberartcenter.com) (www.digitalyeil.co.kr)', http://www.schooleweb.co.kr/, htp://www.startstudy.co.kr/among many others. This article suggests several ways to solve the problems web based design education faces, including the lesson should inevitably combine the outline and of online study.

The curriculum analysis of lighting design course in the Interior architecture departments in American universities reveals they share a major concern in the basic lighting theories, the sorts of light source and lighting equipment, daylighting, and interior lighting plav. The curriculum is usually composed of two semesters, the first semester being about lighting theory and simple project, while the second one abut more professional fields of design studio. The curriculum of lighting design at the Interior architecture departments in Korean colleges and universities usually consists of introductory courses in the field. Almost every institution allocated only one semester for the courses, and as the courses should cover the broad range within a short time, they were lacked in the required depth and systematic approach. The analysis also reveals the curriculum in Korea puts emphasis on the interior lighting equipment design, while disregarding the importance of daylighting. In comparison, American institutions have their curriculum focused upon the use of daylighting. The curriculum of lighting design courses in Korea, a major part of space rendering methods in the field of Interior Architecture, should be improved without delay. The courses should be included in the required subjects and the educational aims should be changed from offering a general understanding of the concepts to providing professional knowledge and skills, which would contribute to the competitiveness of the departments.
