신규 건물에 의한 HF 대역 방향 탐지 왜곡 여부를 알아보기 위하여 상용으로 사용 가능한 전자기 산란 프로그램을 이용한다. 지형, 건물, 안테나 시스템 등이 포함된 모델을 이용하여 어레이 매니폴드를 구한다. 안테나 시스템 주변의 신축건물이 존재 시 안테나 응답을 이용하여 신축건물에 의한 방향 탐지 영향 여부를 조사한다. 방향 탐지 알고리즘은 MUSIC과 interferometer를 이용하였다. The effect of new building on the HF direction finding(DF) is analyzed. Commercially available software is used to get array manifold of the HF DF system. The terrain, building and the array antenna system are modelled. New building near the antenna system is also modelled to see whether it actually has an effect on the performance of the DF system. MUSIC and interferometer DF algorithms have been employed.

The purpose of this study is to suggest the direction of the development of the working memory assessment tool based on Baddeley(2018)’s working memory multicomponent model. To do this, we first examined the concept of working memory and neurological basis through literature review, and selected measurement factors for development of working memory assessment tool. Based on the selected measurement factors, we analyzed the developed tasks of working memory tools and revealed its characteristics and limitations. We suggest the points to be considered by the developer and the assessment tool user when developing or using the work memory assessment tool and suggested suitable tasks for each work memory measurement factors. This study is significant in that it establishes the neurological basis of working memory and suggests the points to be considered by the developers and the authors, thereby providing a basis for the development of the working memory assessment tool.

For the roadway implementation, the decision makers generally want to see a ratio of roadway area to urbanized area. However, the conventional evaluation index, roadway ratio, is not appropriate for evaluating the level of roadway establishment in urban area, since the index does not reflect the roadway functions such as highway, arterial road, collector road and so forth. The main purpose of this study is to revise the evaluation index developed by Son(2002). The revised evaluation index is able to represent the level of roadway establishment in urban area properly. The basis of revised index is to consider the amount of activity and the roadway capacity within the area to be interested. The revised index is able to represent the level of roadway establishment in urban area reasonably, and to fgure out the social and economic situation in the area interested.
