Affective aspects of design attributes such as color, Pattern, and texture are important to the overall impression and the success of interior products. Among all the interior materials, wallpapers and flooring materials take up largest construction area and they are main components in creating affective impression for customers. This study aims to investigate the relationship between luxuriousness and related affective variables and design elements of wallpapers and flooring materials. The approach consists of 3 steps: (1) selecting related affective features and product design attributes through a literature survey, opinion of expert panel, and focus group interview, (2) conducting evaluation experiments, and (3) developing Kansei models using multivariate statistical analysis and analyzing critical attributes. Evaluation experiment was conducted using a questionnaire made up of 7-point scale and 100-point scale and 30 housewives and 20 interior designers participated in the evaluation experiment. The result of evaluation was analyzed through principal component regression and quantification I analysis. As a result of analyzing the survey data, the relationship between luxuriousness and related affective features and product design attributes was identified, moreover a optimal combination of the design component was identified. Consequently, it is expected that the results of the study would be a basis of the concept of emotion-based design by giving insights about how customers perceive the luxuriousness and suggesting the optimal combination, and providing specific quantitative design guidelines.

There have been many discussions on the importance and part of quality in the marketing field. It also has been an effort in the cooking field to understand how the quality, recognized by customers, influences customer satisfaction in the process of serving western food. This study is a theory about evaluation methods of western food. It can be summarized in three views as below especially with sensuous evaluation methods. First, it is decoration. Visual factors, such as a receptacle and the amount of food in it, the arrangement of food colors, gloss of food, steam arising of from food, additional garnishes on food should be harmonious. Second, it is a flavor. The factors like the taste and smell of food, and feeling of food in the mouth can be evaluated with the taste and the smell. Third, it is texture. It is considered with the sense of touch, the motor sensation in the mouth and the hearing sense. Especially the sense of touch involves feel of receptacle when it is hot or cold as well as feel of food. This study has been conducted for providing customers with higher-quality western food, which is based on a theoretical study about evaluation methods. During the study, the limit was found that there is no measuring instrument, since the study was restricted in a theoretical work. For more accurate research, the measuring instrument should be developed through the positive research.

The emotional information processing is to simulate and recognize human sensibility, sensuality or emotion, to realize natural and harmonious human-machine interface. This paper proposes an emotion-based image retrieval method. In this method, user can choose a linguistic query among some emotional adjectives. Then the system shows some corresponding representative images that are pre-evaluated by experts. Again the user can select a representative one among the representative images to initiate traditional content-based image retrieval (CBIR). By this proposed method any CBIR can be easily expanded as emotion-based image retrieval. In CBIR of our system, we use several color and texture visual descriptors recommended by MPEG-7. We also propose a fuzzy similarity measure based on Choquet integral in the CBIR system. For the communication between system and user, a relevance feedback mechanism is used to represent human subjectivity in image retrieval. This can improve the performance of image retrieval, and also satisfy the user's individual preference.

The purpose of this study is to analyze the tech fatale fashion image in female models of mobile advertisements and to find the fashion characteristics. The tech fatale emerging as new culture code is a compound word of the femme fatale and technology. It is characteristics of the femme fatale, the post digital culture and the female leadership. The findings of the study were as follows : The tech fatale types were the independence, the transformation and the tradition. The independence was a self expression, appealed to visual image, was showed the coating fabric, denim, space look and street fashion and reflected the creativeness and digital generation. The transformation appealed to sexuality and was showed luster fabric, exposure, body-conscious, glam look. The voluptuous beauty represented the pride of the post digital generation. The tradition appealed to emotion and was showed pale color, simple line, soft texture fabric and a feminine Image. The meanings of tech fatale were the imagination, the public, the duality, the game, the purity and the recurrence. The formative characteristics reflect the mind of post digital generation who is against authority and pursues the human being worth such as the identity establishment and the pure emotion.

본 논문에서는 3D 애니메이션 도구인 마야를 이용하여 태양계를 모델링하고 각 행성의 움직임과 물리적인 속성들을 정밀하고 객관적으로 구현하여 태양계의 구조를 시각적으로 쉽게 이해할 수 있도록 시뮬레이터를 구현하였다. 메뉴를 이용한 마야의 모델링으로는 정밀한 물리적 속성 값을 표현하기 어려우므로 파이선 스크립트를 이용하여 각 행성의 특성을 표현하였다. 제안하는 시뮬레이터는 가상현실 분야나 학생들의 교육 자료로서 사용 가능하도록 모델링과 렌더링을 실사와 동일하게 구현하였다. 또한 마야 애니메이션에서의 메뉴를 이용한 모델링과 스크립트 언어인 파이선을 활용하여 누구라도 쉽게 실사 영상을 볼 수 있도록 하였다.

This paper presents a compression scheme for mesh geometry, which is suitable for mobile graphics. The main focus is to enable real-time decoding of compressed vertex positions while providing reasonable compression ratios. Our scheme is based on local quantization of vertex positions with mesh partitioning. To prevent visual seams along the partitioning boundaries, we constrain the locally quantized cells of all mesh partitions to have the same size and aligned local axes. We propose a mesh partitioning algorithm to minimize the size of locally quantized cells, which relates to the distortion of a restored mesh. Vertex coordinates are stored in main memory and transmitted to graphics hardware for rendering in the quantized form, saving memory space and system bus bandwidth. Decoding operation is combined with model geometry transformation, and the only overhead to restore vertex positions is one matrix multiplication for each mesh partition. In our experiments, a 32-bit floating point vertex coordinate is quantized into an 8-bit integer, which is the smallest data size supported in a mobile graphics library. With this setting, the distortions of the restored meshes are comparable to 11-bit global quantization of vertex coordinates. We also apply the proposed approach to compression of vertex attributes, such as vertex normals and texture coordinates, and show that gains similar to vertex geometry can be obtained through local quantization with mesh partitioning.

To develop functionally and nutritionally improved whole soybean curd (WSC), the effects of partial (0~4%) replacement with pine needle powder (PNP) on the quality characteristics of WSC were investigated. The moisture content and pH ranged from 76.96~77.80% (wet basis) and 6.69~6.74, respectively, with no considerable differences. Lightness significantly decreased with higher PNP content in the formulation (P<0.05), as indicated by visual observation that the color of WSC became darker. Redness and yellowness also significantly decreased (P<0.05). The texture profile analysis indicated that WSC containing PNP was softer and less cohesive than control WSC. 2,2-Diphenyl-1-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) radical scavenging activities significantly increased (P<0.05) with higher substitution of PNP, and they were well correlated. Results from the consumer test revealed that WSC with 1% PLP received the most favorable acceptance scores for sensory attributes, including overall acceptability. The present study indicated that the characteristics of PNP may play a role in improving WSC quality in terms of physicochemical, sensorial, and antioxidant characteristics.

Rapid object recognition is one of the main stream research themes focusing to reveal how human recognizes object and interacts with environment in natural world. This field of study is of consequence in that it is highly important in evolutionary perspective to quickly see the external objects and judge their characteristics to plan future reactions. In this study, we investigated how human detect natural scene objects and categorize them in a limited time frame. We applied Magnetoencepahlogram (MEG) while participants were performing detection (e.g. object vs. texture) or basic-level categorization (e.g. cars vs. dogs) tasks to track the dynamic interaction in human brain for rapid object recognition process. The results revealed that detection and categorization involves different temporal and functional connections that correlated for the successful recognition process as a whole. These results imply that dynamics in the brain are important for our interaction with environment. The implication from this study can be further extended to investigate the effect of subconscious emotional factors on the dynamics of brain interactions during the rapid recognition process.

Low-rank matrix decomposition has shown its capability in many applications such as image in-painting, de-noising, background reconstruction and defect detection etc. In this paper, we consider the texture background of rail track images and the sparse foreground of the defects to construct a low-rank matrix decomposition model with block sparsity for defect inspection of rail tracks, which jointly minimizes the nuclear norm and the 2-1 norm. Similar to ADM, an alternative method is proposed in this study to solve the optimization problem. After image decomposition, the defect areas in the resulting low-rank image will form dark stripes that horizontally cross the entire image, indicating the preciselocations of the defects. Finally, a two-stage defect extraction method is proposed to locate the defect areas. The experimental results of the two datasets show that our algorithm achieved better performance compared with other methods.
