Previous multimodal learning methods focus on problem-solving aspects, such as image and video search and tagging, rather than on knowledge acquisition via content modeling. In this paper, we propose the Multimodal Concept Hierarchy (MuCH), which is a content modeling method that uses a cartoon video dataset and a character-based subtitle generation method from the learned model. The MuCH model has a multimodal hypernetwork layer, in which the patterns of the words and image patches are represented, and a concept layer, in which each concept variable is represented by a probability distribution of the words and the image patches. The model can learn the characteristics of the characters as concepts from the video subtitles and scene images by using a Bayesian learning method and can also generate character-based subtitles from the learned model if text queries are provided. As an experiment, the MuCH model learned concepts from 'Pororo' cartoon videos with a total of 268 minutes in length and generated character-based subtitles. Finally, we compare the results with those of other multimodal learning models. The Experimental results indicate that given the same text query, our model generates more accurate and more character-specific subtitles than other models.

This study was conducted to verify the relationships among the image of middle-low price chain hotels, service quality, consumption value, and customer emotion by using the AMOS 22.0 statistic package program. Confirmatory factor analysis and structural equation modeling methods employed for identifying the formulated hypothesis model. According to results, first, it is seen that the image of middle-low price chain hotels has positive effect on the service quality. Second, the image of middle-low price chain hotels has positive effect on the consumption value, and the consumption value has positive effect on the service quality. Third, the service quality does not have positive effect on the customer emotion. Last, the image of middle-low price chain hotels has positive effect on the customer emotion. In this study, we attempted to establish the management strategy device of middle-low price chain hotels by analyzing how the image of middle-low price chain hotels affect the service quality, consumption value, and customer emotion. As a result, when it comes to the service quality according to the image of middle-low price chain hotels, the conviction, in other words, the belief of the hotel staffs was the biggest one. In addition, when it comes to the consumption value according to the image of middle-low price chain hotels, the functional value, the kind service of the hotel staffs was seen as the highest satisfaction. More practical and theoretical implications for developing marketing strategy in context of middle-low price chain hotels has been suggested in conclusions.

Weather radar images can be used in a variety of ways because of their high visibility in terms of visuals. In other words it has the advantage of being able to grasp the flow of weather phenomena using not only the raw data of the weather radar, but also the change characteristics between consecutive images. In particular image processing techniques are gradually expanding in the field of meteorological research, and in the case of image data having high resolution such as weather radar images it is expected to produce useful information through a new approach called image processing techniques. In this study the weather phenomena flow was calculated as a vector from the change of the weather radar image according to time interval with the optical flow method, one of the image processing techniques. The characteristics of the weather phenomena to be analyzed were derived through vector analysis resolution suitable for the scale of weather, vector interpolation in regions where no radar echo exists, and the removal of relative flow vectors to distinguish the flow of specific weather and the entire atmosphere. Through this study, it is expected that not only the use of raw data of weather radar, but also the widening of the application area of weather radar, such as the use of unique characteristics of image data, and the active use of image processing techniques in the field of meteorology in the future.

The purpose of this study is to establish a new method to develop the textile pattern design using Saengbul flower in Seo-cheon flower garden of Jeju Myth, in other words, to create mythic textile patterns by borrowing effectively from the mythic image of Saengbul flower. Seo-cheon flower garden is an incantation space and Saengbul flower means pregnance. Therefore, we drew Camellia flower motifs from a mythic image based on archetypal symbols about the Saengbul flower, and created mythic patterns. In order to achieve this textile pattern design, Adobe CS5(Photoshop, Illustrator) and Texpro were used to design the motifs of Saengbul flower, and then they were arranged in a square pattern and diamond pattern of Richard M. Proctor' set layout. And to conclude, development of the creative textile pattern design using the mythic contents of the Jeju Myth contribute to invigoration the fashion industry and regional culture contents projects in Jeju, and also become the basis of creating added valued to it.

As a mirror of its time, fashion exactly reflects the trend of today' s society. In addition, as a tool to satisfy our desire and express images, it brings diverse image changes in people's minds. This kind of pattern is frequently found in wedding images, especially in wedding dresses. When it comes to a wedding dress, in general, we often think of a modest and pure-white one. In modem times, however, people prefer a differentiated image which reflects their personality and ego. In other words, it is an important means of expressing their own personality by focusing on their active and personal aspects and getting away from the passive, stable and formative aspects in the past. These days, a combination of narcissism and eroticism is found on wedding dresses. This kind of trend has been expressed into romanticism. In terms of the latest sensitive wedding dress trend, unique and creative couture wedding dresses have appeared. Therefore, this study has classified this kind of trend into two categories; Formative and Design aspects. According to an analysis on the formative and design aspects of romanticism in wedding dresses, diverse characteristics were observed in shape, color, material and ornament in the Formative Aspect. In terms of design, the characteristics of sensuality, ornament, exoticism and compromise were observed.

Comparing with fixed-type Robots, Mobile Robots have the advantage of extending their workspaces. But this advantage need some sensors to detect mobile robot's position and find their goal point. This article describe the navigation teaching method of mobile robot using omni-directional position detection system. This system offers the brief position data to a processor with simple devices. In other words, when user points a goal point, this system revise the error by comparing its heading angle and position with the goal. For these processes, this system use a conic mirror and a single camera. As a result, this system reduce the image processing time to search the target for mobile robot navigation ordered by user.

One of the ways to measure the distance in the computer vision is to use the focus and defocus. There are two methods in this way. The first method is caculating the distance from the focused images in a point (MMDFP: the method measuring the distance to the focal plane). The second method is to measure the distance from the difference of the camera parameters, in other words, the apertures of the focal planes, of two images with having the different parameters (MMDCI: the method to measure the distance by comparing two images). The problem of the existing methods in MMDFP is to decide the thresholding vaue on detecting the most optimally focused object in the defocused image. In this case, it could be solved by comparing only the error energy in 3x3 window between two images. In MMDCI, the difficulty is the influence of the deflection effect. Therefor, to minimize its influence, we utilize two differently focused images instead of different aperture images in this paper. At the first, the amount of defocusing between two images is measured through the introduction of regularization and then the distance from the camera to the objects is caculated by the new equation measuring the distance. In the results of simulation, we see the fact to be able to measure the distance from two differently defocused images, and for our approach to be robuster than the method using the different aperture in the noisy image.

Objective: The goal of this study is to examine child care center teachers'awareness of parents through a metaphor analysis. Methods: Metaphorical expressions and reason-statements were collected from 276 teachers. Metaphor analysis was used through categorizing and assorting by meanings. Results: The teachers' metaphorical image expressions of parents were analyzed by using 13 metaphorical expression words and 3 categories which included, influence on teacher's attitudes, parent-teacher relationships, and parents' attitudes. Metaphorical image expressions that had a high ratio were 'a companion' and 'a client.' First, child care center teachers had images of parents that parents provide courageous energy to them, and images of clients who demand service instead of being parents. Second, child care center teachers had images of parents that parents cooperate with teachers for the sake of their children. Third, child care teachers had images of parents that parents need help with their children. Conclusion/Implications: This study suggests that teachers will be able to positively correct their awareness of cooperative parent-teacher relationships by reviewing their metaphorical expressions of parental images.

The movie costumes, artistic and figurative, serve to maximize the dramatic conveying effect of the movie's theme, actor's character, and the image of a dramatic situation expressed through clothing. It is considered that research would be meaningful if it studied on how the movie costumes are implied with symbols in order to present a dramatic image depending on the situation. Therefore this research compared, analyzed, and interpreted the historical plays produced on historical backgrounds, "The Sword With No Name" and 'Elizabeth - Golden Age'. In other words, five dramatic situations were extracted in order to compare and analyze the costumes of Empress Myeongseong to the costumes of Queen Elizabeth. The costumes presented according to the storyline and the personalities of the two characters with these five as the basis are compared and analyzed, and the implied symbolic meaning could be interpreted and analogized based on the results. Therefore it is suggested that symbolic meaning, along with the expression of the dramatic atmosphere, needs to be implied in the design of the movie costumes.

A two-phase flow observed in a heat exchanger or nuclear power generation often has a profound effect on undesirable noise or flow characteristics. Void fraction, which refers to the ratio of gas (or liquid) to the total fluid, affects heat transfer coefficient, vibration and so forth. In other words, void fraction is one of most important parameters in two-phase flow since it contributes to comprehend the characteristics of two-phase flow. We developed a two-phase flow visualization system to measure cross-sectional and volumetric void fractions by using quick closing valves and image processing software. With this system, we could observe the plug, slug, and stratified flow patterns of two-phase flow and measure a myriad of void fractions. As a consequence of the experiment, we found that the estimated void fractions were largely coincident with the predictive values by Chisholm model.
