This study examined the domains of moving path-based gaze information through realtime eye tracking of continued circulation of commercial spaces and analyzed spatial components. In order to get over the limitation of space evaluation targeting filming images in the existing space evaluation studies using eye tracking, eye tracking of continued circulation presented in the video filmed, not the department store’s space images was conducted. As the result, it facilitated user’s direct space evaluation more. The results of the acquisition method of gaze information of spatial components in continued circulation of the department store are as follows. First, for an equal comparison of each section, five spheres were set depending on the gaze frequency per second and spatial components of the division in sphere 1 with the highest gaze frequency were analyzed. As the result, four image sections showed more frequent movements of gaze at the display method of the right store. Second, in relation to spatial components of the stores, it was found that the right store used the same display method as the showcase in the store. This means that the subjects gazed at the display of the right store more than the stand or the hanger-type display of the left store. In conclusion, it is considered that for space design of commercial facilities, this analysis method makes it possible to analyze design elements and spatial characteristics, which catch the attention of consumers, and the characteristics of spatial components examined in this study could be applied to design through diverse approaches that take product display methods and heights of product display preferred by consumers into account. It is anticipated that if further research analyzes movements of gaze along with gaze information of grid area would, based on gaze information from each subject, it would be possible to provide design data for applying to displays of commercial spaces.

Gaze induction characteristics in space vary depending on characteristics of spatial components and display. This study analyzed dominant eye-fixation characteristics of three zones of department store space. Eye-fixation characteristics depending on spatial components and positional relationship can be defined as follows. First, [**.jpg] was used as an extension in the process of storing the image photographed during image data processing for analysis in pixels and due to compressed storage of image data, the image produced with a clear boundary was stored in neutral colors. To remove this problem, the image used in operation was re-processed in black and white and stored in the [**.bmp] format with large capability, at the same time. As the result, the effort caused by unnecessary colors in the program operation process was corrected. Second, the gaze ratio to space area can be indicated as a strength of each gaze zone and when analyzing the gaze strength of the three zones, the left store was a zone with a 「little strong」 gaze strength of 「102.8」, the middle space was a zone with an 「extremely weak」 gaze strength of 「89.6」 and the right store was a zone with an 「extremely strong」 gaze strength of 「117.2」. Third, the Ⅳ section had a strong strength of gaze on the middle space and the right store and the Ⅴ section showed a markedly strong strength of gaze on the left and right stores. This tendency was the same as the Ⅵ section with the strongest gaze strength and the right store had a little strong gaze strength than the left store.

Two-dimensional unsteady flows and heat transfer around four circular cylinders are numerically studied. When Re=100, the arrangement of four cylinders is changed as the form of square, a rectangle and trapezoid. The results show that the wall heat transfer rate is strongly dependent on the cylinder arrangement.

본 연구는 백화점 로비공간 이미지의 주시특성을 분석하기 위해, 여성을 대상으로 한 의식조사와 이미지의 유형화를 통해 대표 이미지를 선정하였다. 성별에 따른 주시에 차이가 있는 관계로, 주시실험은 여성을 대상으로 실시하였으며, 피험자는 목적성 문구를 듣고 실험에 임하였다. 실험을 통해 획득한 주시데이터를 대상으로 디자인 차이에 나타난 로비공간의 주사유형을 정리하였는데, 이상의 연구를 통해 정리한 결과는 다음 몇 가지로 정리할 수 있다. 첫째, 백화점이 가지고있는 전체적인 이미지는 고급스러움이 37.4%로 가장 높았으며, 디스플레이(51.7%)가 공간을 구성하는 대표요소로 나타났다. 둘째, 이미지 유형별 주사유형의 출현빈도를 보면, 시작은 A 형 이미지가 B 형에 비해 높았으나 Ⅳ구간(30-40 초)을 지나면서 빈도가 역전되어 B 이미지에 대한 주사빈도가 높았는데, 이것은 B 형의 공간특성이 더 높은 주사 빈도를유발한 것으로 보인다. 셋째, 시간구간 별 주사유형의 빈도분석결과, A 형 이미지는 「집중, 대각」, B 형 이미지는 「혼합, 대각」이 높았다. 「대각」은 A, B 유형 모두 25.4%, 25.1%로 비슷하게 나타나고 있어 공간특성과 무관한 것으로 보인다. 한편 유형별 비교에서 「집중」은 A 형이 8.3%, 「혼합」은 B 형이 9.9% 높았는데, 디자인유형의 차이로 인해 A 형은 「집중」을 B 형은 「혼합」주사를 강하게 유발하는 공간특성을 가진 것으로 볼 수 있다. This study has selected the representative images from the survey of women`s awareness and stereotyping of images in order to analyze the observation features of images at lobbies of department stores. Since there are differences between males and females, the experiment was conducted only with women, where the subjects were made to listen intentive phrases first before the experiment. The data acquired from the experiment have been applied for summarize the scanning patterns shown at diverse designs. The followings are the findings from the research. First, the luxury of the overall image of department stores was found to be the most (37.4%), the display (51.7%) being found to the representative element composing of the space. Second, given the appearing frequency of scanning pattern by image, the beginning with Image A was found to be higher than that with Image B, while with the pass through Range IV (30~40seconds), the scanning frequency of Image B was revealed to be higher, where the space features of Image B is thought of having caused higher frequency. Third, the estimation of the frequency of scanning pattern by time range has indicated that Image A has more “concentration, diagonal” and Image B more “combination, diagonal”, while both Images of A and B were found to have almost the same amount of “diagonal” with 25.4% and 25.1%, which explains that images are not related to space features. On the other hand, at the comparison of patterns, Image A had 8.3% higher “Concentration” and Image B higher 9.9% “Combination”, which makes it possible to assume that the differences among design types have the space features causing Image A to have higher “Concentration” and B to be with stronger “Combination” scanning.
