The development of Wireless Multimedia Sensor Networks(WMSNs) is getting realized in accordance with the increased demands to provide multimedia data transmission service such as CCTV movie, image chapter information, audio information based on wireless sensor network. It is very important to provide the differentiated quality assurance of service. In this paper, we propose a sensor medium access control protocol based on DSMAC, which provides differentiated Quality of Service(QoS) for delay. A proposed protocol is able to reduce the delay without increasing the energy consumption by adaptively changing the duty cycle according to the buffer occupancy. Simulation results show that the new MAC protocol performs better in terms of latency than S-MAC and DSMAC.

In film, color is a tool for storytelling and a metaphor for a story's theme. This study constructs efficient and objective data by analyzing color images of movies delivered to the audience. This Research the visual perception process of color in films and studies the processes accepted by the audience. Through this research process, we examine the emotional response caused by the visual stimulus of film color and quantify the visual factor through color in the film as a factor that effectively induces the emotional response of viewers who watch the movie. This study analyzes the mise-en-scene of Wes Anderson's film, Royal Tenenbaum, and studies the role of communication in cinematic colors. Quantitative analysis of color distribution data is performed using computer color analysis program on the colors displayed through 10 chapters of mise en scene. Through color analysis, it was analyzed that Anderson composed the movie scenes in red and yellow red (YR) with low saturation and medium brightness. Through this analysis, we study how color is used throughout the film and how the quantitative form of its use is to be used as the psychological factor controlling audience's emotion.

With the development of 3D graphics software and the speed of computer hardware, it is an era that can be realistically expressed not only in movie visual effects but also in console games. In the production of such realistic 3D models, 3D scans are increasingly used because they can obtain hyper-realistic results with relatively little effort. Among the various 3D scanning methods, photogrammetry can be used only with a camera. Therefore, no additional hardware is required, so its demand is rapidly increasing. Most 3D artists shoot as many images as possible with a video camera, etc., and then calculate using all of those images. Therefore, the photogrammetry method is recognized as a task that requires a lot of memory and long hardware operation. However, research on how to obtain precise results with 3D photogrammetry scans is insufficient, and a large number of photos is being utilized, which leads to increased production time and data capacity and decreased productivity. In this study, point cloud data generated according to changes in the number and resolution of photographic images were produced, and an experiment was conducted to compare them with original data. Then, the precision was measured using the average distance value and standard deviation of each vertex of the point cloud. By comparing and analyzing the difference in the precision of the 3D photogrammetry scans according to the number and resolution of images, this paper presents a direction for obtaining the most precise and effective results to 3D artists.

The foodservice industry is applying new marketing strategies, and advertisements are the best way to convey their distinctive brand images. The foodservice companies have been choosing a type of advertising called Product Placement(PPL) because it is unconsciously shown more often than other types of advertisements while customers are watching a movie or TV drama. Therefore, the aims of this research were to investigate the influence of the customers' perception of PPL inserted into TV dramas on brand image and purchasing intention. Additionally, present study performed to identify the differences between Korean and Chinese customers. For the survey, the study used both offline and online sampling methods, and the analyzed data was from 150 Korean and 150 Chinese respondents. As results, the more respondents were positive and familiar about PPL, the higher the brand image and purchasing intention. Chinese consumers had positive perception of PPL, which positively influenced the brand image and purchasing intention while Korean consumers' ethical awareness about PPL had a negative influence. Therefore, the Korean foodservice industry needs to differentiate the strategies for the PPL marketing between the Korean and Chinese market.

The purpose of this study is to delineate and analyze the expression of the kidult and its characteristics and thereby provide data to be used for fashion design in various manners as well as to suggest creative and varied possibilities of fashion design. As a way to study, the author of this paper organized the general terms, concepts and definitions concerning the kidult in the previous papers and journals. The data was collected from the collections represent the characteristics of kidult especially from 2006 to 2015. The results are as follows: Firstly, The characters stimulating the innocence of children were used the most for infantile expression. Parody used characters in the movie or famous logos. Deformation was used to create designs by way of distortion and deformation. Exaggeration thereby showing visually strong impression and inducing surprise and unexpectedness. Depaysement was useful to let us describe concepts and enhance our infinite creativity and interests about objects using surrealistic. Secondly, Infantile characteristics used the images of toys with infantile imagination and sense of humor. Fantasy introduced objects or expressed a dream-like feeling. Unexpectedness used two-faced ideas or conflicting ideas to express conflicts, collision and an interchange with heterogeneous things, avoiding the limit of size and the simplicity of materials. Parody used jocular expressions, satire and ironic expressions to express the original image in a fun manner. Exaggeration transformed changed the structure to restructure objects in a subjective and creative manner, thereby expressing creative patterns using various subject matters by way of special modeling or distortion and transformation.

Recent years, the use of multimedia information is rapidly increasing, and the video media is the most rising one than any others, and this field Integrates all the media into a single data stream. Though the availability of digital video is raised largely, it is very difficult for users to make the effective video access, due to its length and unstructured video format. Thus, the minimal interaction of users and the explicit definition of video structure is a key requirement in the lately developing image and video management systems. This paper defines the terms and hierarchical video structure, and presents the system, which construct the clustering-based video hierarchy, which facilitate users by browsing the summary and do a random access to the video content. Instead of using a single feature and domain-specific thresholds, we use multiple features that have complementary relationship for each other and clustering-based methods that use normalization so as to interact with users minimally. The stage of shot boundary detection extracts multiple features, performs the adaptive filtering process for each features to enhance the performance by eliminating the false factors, and does k-means clustering with two classes. The shot list of a result after the proposed procedure is represented as the video hierarchy by the intelligent unsupervised clustering technique. We experimented the static and the dynamic movie videos that represent characteristics of various video types. In the result of shot boundary detection, we had almost more than 95% good performance, and had also rood result in the video hierarchy.
