This study aims to find out the influence of brand awareness and preference of collaboration products created by SPA and luxury brands using specific examples of collaborations, which are now becoming prevelent in the fashion industry. For this study, data collection was carried out through a distribution of 350 copies of the questionnaire, 333 responses were used for data analysis. Using a statistical package program with SPSS, a frequency analysis, a factor analysis, and a multiple regression analysis were conducted. The results of this study are summarized as follows. Awareness and preferences of the SPA and luxury brands lead collaboration products to be preferred. In addition, consumers happen to have more favorable attitudes regarding the purchase of collaboration products. This means that matching brands with high preference is a very important factor to create profits from the collaboration products as awareness and the preference are important factors for the success of projects. In particular, the recognition and preference of luxury brands was found to have greater impact on the preference and recognition of collaboration the SPA brands. Accordingly, brands should expand and actively collaborate through a variety of methods and support proper collaborations that fit their image.

In the present study, the interior orientation parameters were computed by using various kinds of methods. Five DSMs (Digital Surface Models) in total were produced by applying interior orientation parameters to the image processing, and the accuracy was evaluated. In order to use interior orientation parameters as independent variables of DSM accuracy, flight parameters and exterior orientation parameters that can affect the accuracy of DSM were set to be the only fixed variables. From the results of the present study, the RMSE of campaign 3-2 was found to be 0.0305 m, which was the most favorable result. Thus, it is advisable to produce DSM by adjusted interior parameters after figuring out the interior orientation parameters using a camera calibration program at laboratory environment.

Smartphone applications like games, image processing, e-commerce and social networking are gaining exponential growth, with the ubiquity of cellular services. This demands increased computational power and storage from mobile devices with a sufficiently high bandwidth for mobile internet service. But mobile nodes are highly constrained in the processing and storage, along with the battery power, which further restrains their dependability. Adopting the unlimited storage and computing power offered by cloud servers, it is possible to overcome and turn these issues into a favorable opportunity for the growth of mobile cloud computing. As the mobile internet data traffic is predicted to grow at the rate of around 65 percent yearly, even advanced services like 3G and 4G for mobile communication will fail to accommodate such exponential growth of data. On the other hand, developers extend popular applications with high end graphics leading to smart phones, manufactured with multicore processors and graphics processing units making them unaffordable. Therefore, to address the need of resource constrained mobile nodes and bandwidth constrained cellular networks, the computations can be migrated to resourceful servers connected to cloud. The server now acts as a bridge that should enable the participating mobile nodes to offload their computations through Wi-Fi directly to the virtualized server. Our proposed model enables an on-demand service offloading with a decision support system that identifies the capabilities of the client's hardware and software resources in judging the requirements for offloading. Further, the node's location, context and security capabilities are estimated to facilitate adaptive migration.

Many works have been published with using surrealism techniques among the representation characteristics of media space of video and art. It has begun to research on these work. But many of these researches have not cover surrealism techniques in game graphic. So, in this paper, we have analyzed representation characteristics of fantasy online game's character using surrealism techniques in surrealism. In result, there are means to express nonexistent image in real world in surrealism by using such as collage of parts of body, animals, and other object, deformation, and distortion. Also, these methods have been used in game characters of online game based on fantasy. We analyzed on characteristics of fantasy game's character in aesthetic point view. It should be profitable for making creative and favorable game characters and making creative game graphic by increasing the possibility of art techniques usage.

With the development of wearable(ubiquitous) computers, those traditional interfaces between human and computers gradually become uncomfortable to use, which directly leads to a requirement for new one. In this paper, we study on a new interface in which computers try to recognize the gesture of human through a digital camera. Because the method of recognizing hand gesture through camera is affected by the surrounding environment such as lighting and so on, the detector should be a little sensitive. Recently, Viola's detector shows a favorable result in face detection. where Adaboost learning algorithm is used with the Haar features from the integral image. We apply this method to hand area detection and carry out comparative experiments with the classic method using skin color. Experimental results show Viola's detector is more robust than the detection method using skin color in the environment that degradation may occur by surroundings like effect of lighting.

This study is aimed for the implementation of ultrasonic method to assess the reliability of turbine bearings. A modified ultrasonic immersion technique was carried out in both laboratory experiment and field application. From the laboratory results, we confirmed that the condition of interface layer between the babbitt and base metal be monitored by the C-Scan. The C-scan image by the ultrasonic immersion test can be used successfully to observe the condition of interface layer. The testing with a focused transducer provides a promising approach for estimating the extent of the damaged region and observing the interface layer effectively. The difference of the ultrasonic reflection ratio between the bonding and debonding area at the interface layer is one of the key parameters for assessing the extent of the damaged area; additionally, the reflection amplitude exhibits a favorable correlation with the overall damage level. The technique developed in this study was applied to the inspection of the turbine bearings at several power plants in Korea whereby the applicability in the field can be ascertained.

Objective : The objectives of this study was to determine the incidence and outcomes of procedural rupture (PR) during coil embolization of unruptured intracranial aneurysm (UIA) and to explore potential risk factors. Methods : This retrospective study evaluated 1038 patients treated with coil embolization between January 2001 and May 2013 in a single tertiary medical institute. PR was defined as evidence of rupture during coil embolization or post procedural imaging. The patient's medical records were reviewed including procedure description, image findings and clinical outcomes. Results : Twelve of 1038 (1.1%) patients showed PR. Points and time of rupture were parent artery rupture during stent delivery (n=2), aneurysm rupture during filling stage (n=9) and unknown (n=1). Two parent artery rupture and one aneurysm neck rupture showed poor clinical outcomes [modified Rankin Scale (mRs) >2] Nine aneurysm dome rupture cases showed favorable outcomes ($mRS{\leq}2$). Location (anterior cerebral artery) of aneurysm was associated with high procedural rupture rate (p<0.05). Conclusion : The clinical course of a patientwith procedural aneurysm rupture during filling stage seemed benign. Parent artery and aneurysm neck rupture seemed relatively urgent, serious and life threatening. Although the permanent morbidity rate was low, clinicians should pay attention to prevent PR, especially when confronting the anterior cerebral artery aneurysm.

Since the arrival of Chinese immigrants in the 1850s, many Euro-American writers tended to project their fears, contempt, desires and fantasy onto the Other race and perceived Chinese Americans in stereotypes-dangerous villains, unassimilated aliens, quiet and passive servants, sexually submissive women, or seductive prostitutes. However in the 1970s and the 1980s Euro-American novels expressed varying attitudes towards Chinese Americans. Many earlier EuroAmerican writers began portraying positive characterizations of Chinese Americans. The purpose of this study is to examine the ways one of the Euro-American writers, Howard Fast characterized Chinese Americans in The Immigrants. Part of the novel concerns a Chinese American family. Fast gave a favorable portrayal of Chinese Americans. Unlike many Euro-American novelists who dealt only with Chinese American villains and prostitutes and view Chinese Americans as the lowest class of American society, Fast, on the other hand, portrayed Chinese Americans as law-abiding and useful citizens. Thus, I will discuss how Howard Fast subverted the familiar negative characterization of Chinese Americans and placed Chinese American experiences in the context of American immigration history. Many white Americans tended to notice only the lurid and sensational aspects in the Chinese American community. They seldom regarded Chinese Americans as people with homes and families and seldom saw Chinese Americans as individuals, as human beings with feelings, pain, and joy. To counter this racist view, Fast described the family life of Chinese Americans and depicted Chinese Americans as individuals with a full range of human emotions and with strong family and cultural ties. Though Fast debunked some myths about Chinese Americans, he also reinforces other stereotypes or some stereotypical illusions about them. In conclusion, I'll demonstrate Fast's work remains an incomplete representation of Chinese Americans.

With the emergence of convolutional neural network in the field of machine learning, the model for solving image processing problems has seen rapid development. However, the computing resources required are also rising, making it difficult to learn from a typical environment. Attention mechanism is originally proposed to prevent the gradient vanishing problem of the recurrent neural network, but this can also be used in a direction favorable to learning of the convolutional neural network. In this paper, attention mechanism is applied to convolutional neural network, and the excellence of the proposed method is demonstrated through the comparison of learning time and performance difference at this time. The proposed model showed that both learning time and performance were superior in object detection based on YOLO compared to models without attention mechanism, and experimentally demonstrated that learning time could be significantly reduced. In addition, this is expected to increase accessibility to machine learning by end users.

This study looks to explore situations in which the authenticity of reality audition programs is inherently distorted by subjective intervention through a theoretical model of existentialism and case study of how it was practiced in an actual program. In detail, we examine the impact on the essence of human subjective intervention and the behavior by free will and use Sartre's existentialism a theoretical model and a Korean audition program series as the case for the study. We believe that the producers intended to narrow the audiences choices by creating a favorable environments for certain participants (trainees as they were called) to be recognized and liked by the voting audiences. We look to "subjectivity," the first principle of existentialism, people determine their essence through free will, and all actions in the production process are aimed at achieving that goal, which keeps the position balance of final debut group by creating the character image and personality through character making, storytelling and increasing or decrease the assigned air-time of each individuals.
