Cartoon contents is strong not original work through only story but culture penetration and high added value of idea had infinite value as entertainment goods. Also, it can extend by emotional contents of Mobile base by communication role as sensible symbol that satisfy various emotion and appetite of expressed opinion is available. This paper wished to take a view of present condition of cartoon industry and development direction through comprehension of cartoon contents business, and to propose goods development way of cartoon contents by the alternative to extend cartoon contents business area.

Tourism industry increasingly rely on information technology (IT) to improve the task performance. Many studies suggested that the evidence of IT showed not only task performance improvement but also organizational performance. Drawing from the resource-based view, technology and task fitness, and marketing orientation theories, this study proposes that IT use influences directly the task performance and proved the effectiveness of IT in the organizations of tourism industry. Further, the innovativeness, resources, and marketing orientation are identified as main determinants of IT use. The use of IT can serve as a catalyst in improving task performance for organizations in tourism industry. Based on data collected from surveying people who work in the tourism industry, the present study shed light on these issues. The findings provide a new perspective of IT effectiveness in the tourism industry. Then, we discussed the theoretical and practical implications.

Background: Work-related fatigue has a strong impact on performance and safety but so far, no agreed upon method exists to detect and quantify it. It has been suggested that work-related fatigue cannot be quantified with just one test alone, possibly because fatigue is not a uniform construct. The purpose of this study is therefore to measure work-related fatigue with multiple tests and then to determine the underlying factorial structure. Methods: Twenty-eight employees (mean: 36.11; standard deviation 13.17) participated in five common fatigue tests, namely, posturography, heart rate variability, distributed attention, simple reaction time, and subjective fatigue before and after work. To evaluate changes from morning to afternoon, t tests were conducted. For further data analysis, the differences between afternoon and morning scores for each outcome measure and participant (${\Delta}$ scores) were submitted to factor analysis with varimax rotation and each factor with the highest-loading outcome measure was selected. The ${\Delta}$ scores from tests with single and multiple outcome measures were submitted for a further factor analysis with varimax rotation. Results: The statistical analysis of the multiple tests determine a factorial structure with three factors: The first factor is best represented by center of pressure (COP) path length, COP confidence area, and simple reaction time. The second factor is associated with root mean square of successive difference and useful field of view (UFOV). The third factor is represented by the single ${\Delta}$ score of subjective fatigue. Conclusion: Work-related fatigue is a multidimensional phenomenon that should be assessed by multiple tests. Based on data structure and practicability, we recommend carrying out further studies to assess work-related fatigue with manual reaction time and UFOV Subtest 2.

An inflow of daylight to the room offers comfortable view environment, psychological and physical security to people in the room and there are merits such as a work efficiency and energy saving. But, it has many problems as an excessive direct sunlight, cooling and heating. We can expect to have energy saving effect for illumination with comfortable view environment creation through control on height of roller shade. This study will be a used a fundamental approach to control on height of roller shade to changing daylight.

Through the computer simulation of virtual reality techniques, prospective clients can experience the surroundings such as the view, traffic and convenience facilities in advance. Also, consumers can reflect their own tastes in the real apartment Interior construction through their own work in relation to furniture arrangement, color choices, etc. inside the apartments. The virtual model house not only replaces the function of the existing model house but it can also provide some services that could not be provided easily due to some restrictions under real conditions. More, it can provide a precise view of the outside appearance and surrounding environment as well as inside the house, as virtual structures on the computer. Consumers can search for the information through the Web in advance and consumer-satisfaction type of apartments can be built. For this purpose, smooth communications among the designers, server managers, and consumers should be achieved as a prerequisite to the delivery of the necessary information.

In this paper we propose skewed angle detection methods for images that contain text that is not aligned horizontally. In most images text areas are aligned along the horizontal axis, however there are many occasions when the text may be at a skewed angle (denoted by 0 < ${\theta}\;{\leq}\;{\pi}$). In the work described, we adapt the Hough transform, Shadow and Threshold Projection methods to detect the skewed angle of text in an input image using the orthogonal angle view property. The results of this method are a primary text skewed angle, which allows us to rotate the original input image into an image with horizontally aligned text. This utilizes document image processing prior to the recognition stage.

To measure the size and weight of the fish, we developed an automatic fish size measurement system using a deep neural network, where the YOLO (You Only Look Once)v3 model was used. To detect fish, an IP camera with infrared function was installed over the fish pool to acquire image data and used as input data for the deep neural network. Using the bounding box information generated as a result of detecting the fish and the structure for which the actual length is known, the size of the fish can be obtained. A GUI (Graphical User Interface) program was implemented using LabVIEW and RTSP (Real-Time Streaming protocol). The automatic fish size measurement system shows the results and stores them in a database for future work.

This purpose of this study was to examine the differences and correlations of marriage and childbirth intentions, work-family conflict, and continuing dance intentions for female dance students and graduated female dancers. The two groups showed significant differences in self-directed view of marriage, work-family conflict, and childbirth intentions. In the whole, there was a correlation among, several factors, and only family health had a significant effect on intention to continue dance.

Fisher Linear Discriminant(FLD) is a sample and intuitive linear feature extraction method in pattern recognition. But in some special cases, such as un-separable case, one class data dispersed into several clustering case, FLD doesn't work well. In this paper, a new discriminant named K-means Fisher Linear Discriminant, which combines FLD with K-means clustering is proposed. It could deal with this case efficiently, not only possess FLD's global-view merit, but also K-means' local-view property. Finally, the simulation results also demonstrate its advantage against K-means and FLD individually.

This paper proposes efficient system for multiview images using backward quadtree disparity estimation. Previous quadtree method usually divides current image. In this work, backward quadtree divides reference image. So, it does not need to code quadtree data. For backward quadtree, quadtree information map is generated. By using this map, adaptive dividing is possible. And, conventional bi-directional matching method is used with backward quadtree. These methods increase subject and object quality of decoded test images. For multiview images, panorama synthesizing method was used. Panorama image and right-most image are used for reference image for intermediate view images coding.
