  • Images and Videos that include the human face contain a lot of information. Therefore, accurately extracting human face is a very important issue in the field of computer vision. However, in real life, human faces have various shapes and textures. To adapt to these variations, A model-based approach is one of the best ways in which unknown data can be represented by the model in which it is built. However, the model-based approach has its weaknesses when the motion between two frames is big, it can be either a sudden change of pose or moving with fast speed. In this paper, we propose an enhanced human face-tracking model. This approach included human face detection and motion estimation using Cascaded Convolutional Neural Networks, and continuous human face tracking and modeling correction steps using the Active Appearance Model. A proposed system detects human face in the first input frame and initializes the models. On later frames, Cascaded CNN face detection is used to estimate the target motion such as location or pose before applying the old model and fit new target.

  • This research aims at identifying the goshawk's possible and replaceable breeding ground by using the MaxEnt prediction model which has so far been insufficiently used in Korea, and providing evidence to expand possible protection areas for the goshawk's breeding for the future. The field research identified 10 goshawk's nests, and 23 appearance points confirmed during the 3rd round of environmental research were used for analysis. 4 geomorphic, 3 environmental, 7 distance, and 9 weather factors were used as model variables. The final environmental variables were selected through non-parametric verification between appearance and non-appearance coordinates identified by random sampling. The final predictive model (MaxEnt) was structured using 10 factors related to breeding ground and 7 factors related to appearance area selected by statistics verification. According to the results of the study, the factor that affected breeding point structure model the most was temperature seasonality, followed by distance from mixforest, density-class on the forest map and relief energy. The factor that affected appearance point structure model the most was temperature seasonality, followed by distance from rivers and ponds, distance from agricultural land and gradient. The nature of the goshawk's breeding environment and habit to breed inside forests were reflected in this modeling that targets breeding points. The northern central area which is about $189.5 km^2$(2.55 %) is expected to be suitable breeding ground. Large cities such as Cheongju and Chungju are located in the southern part of Chungcheongbuk-do whereas the northern part of Chungcheongbuk-do has evenly distributed forests and farmlands, which helps goshawks have a scope of influence and food source to breed. Appearance point modeling predicted an area of $3,071 km^2$(41.38 %) showing a wider ranging habitat than that of the breeding point modeling due to some limitations such as limited moving observation and non-consideration of seasonal changes. When targeting the breeding points, a specific predictive area can be deduced but it is difficult to check the points of nests and it is impossible to reflect the goshawk's behavioral area. On the other hand, when targeting appearance points, a wider ranging area can be covered but it is less accurate compared to predictive breeding point since simple movements and constant use status are not reflected. However, with these results, the goshawk's habitat can be predicted with reasonable accuracy. In particular, it is necessary to apply precise predictive breeding area data based on habitat modeling results when enforcing an environmental evaluation or establishing a development plan.

  • The purpose of this study is to identify conceptual constructs of well-being consciousness and appearance management behaviors, and to examine the effects of these two variables on attitudes toward Korean herbal cosmetics for Korean and Japanese consumers. A survey was carried out among female consumers between the ages of 20 and 50, and a total of 500 responses were analyzed by descriptive analysis, reliability test, t-test, and confirmatory factor analysis, structural equation modeling and multi group analysis. The results of this study were as follows: 1) The result of CFA and the reliability test on well-being consciousness and appearance management of Korean and Japanese respondents clearly showed factorial structures on each of the variant assessments. 2) In regards to the well-being consciousness, Korean and Japanese respondents highly tended to perceive well-being as a benefit to the physical health and an eco-friendly lifestyle respectively. In the area of appearance management, Korean and Japanese respondents had similar patterns that showed high scores of skin care and weight control. Both Korean and Japanese consumers showed favorable attitudes toward Korean herbal cosmetic products. 3) The consumers' well-being consciousness revealed to have positive influences on appearance management behavior. Both well-being consciousness and appearance management positively influenced attitudes toward Korean herbal cosmetics. 4) As a result of MGA, the well-being consciousness had more positive impacts on Korean respondents' attitudes toward Korean herbal cosmetics than the appearance management variable when compared to the Japanese respondents. On the other hand, appearance management had more positive impacts on Japanese respondents' attitudes to-ward Korean herbal cosmetics than well-being consciousness when compared to the Korean respondents. These results suggest that differentiated marketing strategies for Korean herbal cosmetics are crucial when targeting Korean and Japanese consumers.

  • Faces play a key role in revealing the personalized attributes such as the identity, emotion, health condition, etc. Due to the importance of faces, computer-assisted face modeling and reconstruction have been actively studied both in computer vision and graphics community. Especially, face reconstruction and realistic face synthesis are well-grounded research problems and various approaches have been proposed during the last decade. In this paper, we discuss a wide range of existing work in face modeling by introducing their target applications, categorizing them upon their methodology and addressing their strength and weakness on performance. Finally, we introduce remaining research issues and suggest the future research direction in face modeling. We believe that this paper provides a high-level overview on face modeling techniques and helps understand the major research issues and the trends of methodology.

  • The purposes of this study were to verify how internalization of ideal beauty stereotype and objectified body consciousness by sociocultural pressure factors had an influence on body satisfaction and examine the relation between body satisfaction and appearance management behavior. To achieve the purposes, a survey was conducted to 419 female adults, whose ages were from 18 to 29. Data were analyzed by structure equation modeling of Amos 4.0 and SPSS 10.0 program. The results of this study were summarized as follows: First, there were significant differences in sociocultural pressure, objectified body consciousness, internalization of ideal beauty stereotype, body satisfaction and appearance management behavior variables. Second, sociocultural pressure factors such as, family, friends, media had a positive effect on objectification that female adults saw themselves from the viewpoint of a watcher; when females more highly recognized sociocultural pressure like family, friends and media, their satisfaction with body became lower. Third, when females had high tendency of objectification and high body satisfaction, they affirmatively managed their appearance.

  • The present study purported to understand the relationships between SNS appearance-related photo activity, body image and self-esteem among young women. Objectification Theory and Social Comparison Theory explain the process how young women's SNS appearance-related photo activity influence their body satisfaction through a perceived media pressure, objectification of their own bodies and appearance comparison. These process ultimately affect the self-esteem of young female users. A research model was proposed and related hypothesis were examined. We collected an online questionnaire from 400 female participants in their 20's. Data were analyzed using SPSS 23.0 and AMOS 18.0. Structural equation modeling analyses suggested that the proposed research model provided a good fit to the data and supported most hypothesis. The results indicated that the level of SNS appearance-related photo activity significantly influences young female user's body satisfaction and self-esteem. The findings of this study were consistent with previous literature on media and body image. Limitations and future research suggestions were also described.

  • In the last decade, Korean culture has progressively facilitated the assimilation of appearance-related norms established by modern Korean society among young generations in Vietnam. Of note, Vietnamese consumers residing in Korea, under the influence of diverse sociocultural factors, are aligning themselves with an ideal standard of Korean beauty through cultural adaptation. This study explores how Vietnamese students internalize Korean beauty standards and the resultant negative behavioral reactions. We investigated the effects of sociocultural pressures (media, in-group, and out-group pressure) on risky appearance management and irrational purchase behavior by mediating sociocultural internalization toward appearance. We tested how the mechanism underlying these variables differs based on how long one has resided in Korea. A total of 213 female participants were surveyed online. The research model was tested using structural equation modeling through AMOS 22.0. The findings show that media and out-group pressure significantly increased sociocultural internalization, which led to consumer behavior in the form of risky appearance management and irrational purchases. The influence of internalization on consumption behavior was stronger for short-term residents of Korea. This study contributes to the literature on acculturation by investigating how foreign consumers accept the host country's ideal beauty standards.

  • The study aimed to evaluate the appearance of the men's work clothes jumpers developed to suggest the prototype work clothes jumper patterns by using the 3-D clothing simulation technology. The 3-D simulated clothing images considered the upper body features of men in the age range between 20 and 59 in South Korea. A questionnaire survey conducted previously suggested a basic jumper style with shirt collar and snap opening cuffs for the heavy industry workers; and discomforting parts of the work clothes jumper of the subject workers have been referred to for the experimental jumper appearance test. Besides, defining the measurements of men's upper bodies enabled to generate the men's 3-D virtual models representing each age group's average body feature. The significant body measurement factors for men's 3-D body modeling and jumper pattern-making were stature for the height factor; chest, waist and hip circumferences for the circumference factor; waist back, hip and arm lengths and interscye front/back for the length factor; and back neck breadth for the breadth factor and armscye and scye depths for the depth factor. The men's body measurements of 30's were implemented to three experimental jumper pattern-making methods, i.e. the 1st method using the relations based on stature and chest circumference; the 2nd method using the direct body measurements; and the 3rd method adopting the maximum ease amount of given body measurements whether relations or direct measurements except the direct measurement of scye depth. A comparison among the three experimental jumpers' simulated images highlighted that the appropriate ease amount of the jumper gained higher scores in terms of the jumpers' front, side, back and sleeve parts and the total silhouettes. Therefore the 3rd experimental jumper was finally selected for the heavy industry workers.

  • Augmented reality based on projection, called "Spatial Augmented Reality (SAR)", is a new technology that can produce immersive contents by overlapping virtuality and real-world environment. It has been paid attention as the next generation digital contents in media art and human-computer interaction (HCI). In this paper, we present a new methodology to evaluate the product appearance design more intuitively by means of SAR technique. The proposed method first projects the high-quality rendered image considering the optical property of materials onto the mock-up of a product. We also conduct a projector-camera calibration to compensate a color distortion according to a projector, a projection surface and environment lighting. The design evaluation methodology we propose offers more flexible and intuitive evaluation environment to a designer and user (evaluator) than previous methods that are performed via a digital display. At the end of this research, we have conducted a case study for designing and evaluating appearance design of an automobile.

  • In these days the floor vibration is beginning to make its appearance of the environmental dispute in apartment building. Standard floor system are suggested for the settlement of this issue by government. The sound of floor impact sound is needed to secure comfortable quality in housing. Also, it is required an accurate analysis and a proper evaluation for floor vibration. Refine model is necessary for the floor system of housing to analyze accurately the floor vibration. But this refine model is not efficient because it is required so much running time for vibration analysis and it is difficult of modeling of standard floor slab. In this paper, new modeling methods of standard floor slab are proposed for the accurate rigidity evaluation. By using the new modeling method, the accurate vibration response can be obtained and can accurately evaluate the rigidity of standard floor system with resilient materials. Therefore the proposed modeling method is of practical use for vibration analysis of floor system of apartment building.
