Azabudai Hills is located in the area connecting Kamiyacho on the Hibiya Line and Roppongi 1-chome on the Nanboku Line, and was planned as a district with three skyscrapers arranged around a plaza. Based on the concept of a "Modern Urban Village", the project integrates a variety of urban functions, including offices, residences, a hotel, an international school, commercial and cultural facilities. The construction of the 64-story and 330-meter-high, "A block" was extremely difficult due to its large scale and diverse uses. This paper presents a case study of DX challenges to improve productivity and ensure quality, as well as the resulting benefits and future challenges.

SIESTA를 이용하여 GaSe 단일층에서 금속 원자(Ga)를 전이금속 원자(W)로 치환하였을 때($W_{Ga}$)의 구조 deformation, 에너지 안정성, 전자구조와 자성을 확인하였다. 그 결과, 구조가 바뀌면서 평면에 수직한 방향으로 구조 변형이 나타났고, $W_{Ga}$에서 W의 NN는 Se이 되었다. Clean surface만큼 $W_{Ga}$도 안정된 구조임을 알 수 있었다. $W_{Ga}$에서 W에 의한 defect states가 up, down 6개씩 split되어 나타났으며, ${\Gamma}$ point에서 degenerated 경향을 보였다. 또한 W에 의한 magnetic moment는 $1{\mu}_B$인 것을 확인하였다. Defect states는 degenerated $d_{yz}$, $d_{zx}$ orbital character, degenerated $d_{xy}$, $dx^2-y^2$ orbital character, defect states는 $d_z{^2}$ orbital character을 띠는 것으로 나뉘었고, 이에 따라 에너지가 함께 높아졌다.

The purpose of this study is to investigate how the types of perceived brand image related to the main concept building brand equity affect 'brand preference' and 'behavioral intentions'. The perceived brand image is set as the brand image type perceived by the consumer from the image pursued by the corporate brand, while in addition to brand preference, behavioral intentions are set as purchase intention and recommendation intention for the result variables. The result shows that the types of perceived brand image were extracted as 'factor 1(challenge spirit)' and factor 2(reliability) and through the cluster analysis 3 groups under each type were identified. Also, a significant difference between the influence of each type of perceived brand image on 'brand preference', 'purchase intention' and 'recommend intention' was indicated. In addition, the differences of perceived brand image types were found to be higher in order of 'challenge spirit type', 'reliability type', 'integrated type'. The empirical implementation of this study lies in the fact that it classifies the concept of brand image not as a broad theoretical model, but as a model directly related to real consumer perception, and that it gives practical suggestion for brand image management related to advertising.
