Recently, cosmetic shops are facing a complicate economy situation and a great number of brands are attempting two-way communication with customers, not one-way communication. 'Brand' equity is important to deliver virtual brand mark as visual image. We have 4 steps for brand identity structure, and this study is about the first 'brand-awareness' and the second step 'brand-image'. We investigated the correlation between brand-awareness and brand-image after searching which spatial elements are highly effective to both steps as we designated 5 cosmetic shops. We already organized the means of spatial analysis and we separated into two elements, constructive and decorative. For constructive element, a shop needs a distinct ceiling and wall design, and for decorative element, strong brand image communication is required through showcase design. We proved that brand awareness and brand image have the correlation, which also can be in direct proportion, by regression analysis. The result of this study shows that improving brand awareness as the primary element for cosmetic road shop can be an effective way to enhance brand image.

As Korea has rapidly entered the aging society, the Korean government and academia are currently undergoing many researches on senior citizens. There also has been an increase in senior citizens' awareness on the importance of spatial designs that reflect the newly emerged needs brought out by their psychological and emotional changes as well as their physical aspects. Therefore, the purpose of this research is to propose a model for senior citizens' image preference to be adopted in future developments for senior-friendly spatial designs. A literature review and a questionnaire survey were implemented as research methods. The questionnaire survey was conducted at two senior welfare centers located in Seoul and Ansan and two disparate senior colleges, on the subjects of 86 senior citizens aged 60 and older. 7 styles of Romantic, Classic, Country, Modern, Natural, Casual, and Traditional were chosen for the study and the realms to apply the image preference were divided into Space, Element1 and Element2. For Space, its subcategories have been restricted to living room and bedroom while color, furniture and lighting for Element1 and material, pattern and props for Element2. Survey results were statistically analyzed for the correlation among socio-demographic factors of senior citizens, spaces and the elements. The study result showed that older age and men tended to prefer the modern style than younger age or women, and younger women preferred the romantic style. For the color preference in Element1, older men preferred the classic style while women preferred the romantic style. And, for the furniture preference, men with higher income preferred the natural style while women preferred the romantic style. For the pattern preference in Element2, younger people preferred the casual style and it showed that the housing type was the main reason for their preferences. Therefore, the image preference according to their age and gender shall be taken account of as the most important factors when designing environments for senior citizens.

본 논문은 다양한 해상도에서의 초음파 영상 처리를 위한 최적의 프로세싱 엘리먼트 구조를 제안한다. 이를 위해 본 논문에서는 각 프로세싱 엘리먼트(processing element, PE)당 처리되는 영상 데이터(data-per-processing element, DPE) 수를 변화시키는 실험을 통해 시스템의 성능(system performance), 에너지 효율(energy efficiency), 면적 효율(area efficiency)을 각각 측정하고, 측정된 결과를 바탕으로 최적의 매니코어 프로세서 구조를 선택하였다. 모의실험 결과, 에너지 효율은 $256{\times}256$, $768{\times}1,024$, $1,024{\times}1,280$ 해상도를 갖는 영상에서 PE 개수가 각각 1,024개, 4,096개, 16,384개일 때 가장 높았다. 또한 면적 효율은 $256{\times}256$ 해상도의 영상에서는 PE 개수가 256개, $768{\times}1,024$와 $1,024{\times}1,280$ 해상도의 영상에서는 4,096개에서 가장 높은 효율을 보였다.

그레이스케일 수학적 형태학에 기초한 에지 검출 알고리즘의 방법은 영상 노이즈를 제거와 병렬처리 가능하고 연산속도가 빠르다는 장점을 갖고 있다. 그러나 단일 구조적 스케일 요소를 사용하여 영상의 에지 검출을 하는 방법은 영상정보에 따라서 영향을 받을 수 있다. 그레이스케일 형태학의 특성은 구조적원소를 반복하여 확장, 침식, 열림, 담힘 연산을 함으로써 연산 결과 에지정보 결과에 제한적일 수 있다. 본 논문에서 잡음에 강인한 방향성을 갖는 구조적원소를 적용한 후 원소내의 각 픽셀 정보에 가중치 엔트로피를 적용하는 에지 검출 알고리즘을 제안한다. 영상에 적용하는 멀티 스케일 구조적 요소를 적용한 결과와 방향성 가중치 엔트로피를 적용한 연산결과를 비교분석하였으며, 시뮬레이션 결과는 제안된 알고리즘이 에지 검출에서 우수함을 보였다.

Stress wave propagation through concrete is simulated by finite element analysis. The concrete medium is modeled as a homogeneous material with smeared properties to investigate and establish the suitable finite element analysis method (explicit versus implicit) and analysis parameters (element size, and solution time increment) also suitable for rigorous investigation. In the next step, finite element analysis model of the medium is developed using a digital image processing technique, which distinguishes the mortar and aggregate phases of concrete. The mortar and aggregate phase topologies are, then, directly mapped to the finite element mesh to form a heterogeneous concrete model. The heterogeneous concrete model is then used to simulate wave propagation. The veracity of the model is demonstrated by evaluating the intrinsic parameters of nondestructive ultrasonic pulse velocity testing of concrete. Quantitative relationships between aggregate size and testing frequency for nondestructive testing are presented.

Video segmentation is an essential part in region-based video coding and any other fields of the video processing. Among lots of methods proposed so far, the watershed method in which the region growing is performed for the gradient image can produce well-partitioned regions globally without any influence on local noise and extracts accurate boundaries. But, it generates a great number of small regions, which we call over segmentation problem. Therefore we proposes image segmentation improvement by selective application structuring element of mathematical morphology.

Black has been the most important color of all since the ancient times when the recognition of black roused, as well as during most of the eras; and can especially be said as the main color which controlled the chronicles of fashion. The purpose of the study was to broaden the application of black color image make-up by inquiring into make-up design elemental characteristics of lines and textures, after classifying magazine illustrations and advertisement make-up images using black. The photos which made effective use of black among fashion illustrations, magazine advertisements after 2001 were classified in to each type, and make-up expression method and characteristics according to design element of each image type was analyzed. The conclusion of such study was the following. 'Erotic image' showed contrast effect between eye make-up and lip color by using pale tone or red color. 'Mannish image' emphasized form and texture of eyebrow by restraining the colors of eyelids with natural brown tone eye make-up; 'Modern image' expressed vague eyebrow to bring the sensation of the direction of eye shadow on eyelids and eye line as well as slant line to relief. 'Kitsch image' showed free and light imagery by creating unique hair style with various colors; expressing lips mostly with colors similar to skin tone or by restraining colors on lips. 'Decadence image' showed messy and foul sensation with unstandardized eye make-up and matt skin of shimmer, glossy and pale tone, also with black colored lips; 'Retro image' expressed reinterpretation of images from 1920${\sim}$1960 to contemporary styles.
