We developed a novel frame interpolation method to interpolate a frame between two successive original frames. Using this method, we are able to apply a double-rate driving method instead of an impulse driving method where a black frame is inserted between two successive original frames. The double-rate driving method enables amelioration of the motion blur of LCDs caused by the characteristics of human vision without reducing the luminosity of the whole screen. The image quality of the double-rate driving method was also found to be better than that of an impulse driving method using our motion picture simulator and an actual panel. Our initial model of our frame interpolation method consists of motion estimation with a maximum matching pixel count estimation function, an area segmentation technique, and motion compensation with variable segmentation threshold. Although salt and pepper noise remained in a portion of an object mainly due to inaccuracy of motion estimation, we verified the validity of our method and the possibility of improvement in hold-type motion blurring.

In this paper, In this paper, we describe the UAV system using image processing for autonomous quadcopters, where they can apply logistics, rescue work etc. we propose high-speed hovering height and posture control method based on state feedback control with CNN from camera because we can get image of the information only every 30ms. Finally, we show the advantages of proposed method by simulations and experiments.

In recent marketing circumstances we passed the days just dealt with products sales and faced Sensitivity Marketing era concluded by merchandise, corporate and brand image. Especially although corporate commercial space is the important strategy factor performing immediate satisfaction, experience,sensitive stimulation and social relationship among customers, most of the domestic firms don't recognize its importance when looking into adopted graphic factors at spaces without consideration for a variety of space function, concept,merchandise and customer satisfaction. In addition the facade, which performs as visual information conveyance, boundaries of architecture and concluding space concept, merchandise image and incoming customer based on linkage between interior and exterior, is the important point. This research specializing the examples of facade design of corporate and brand commercial space including service, purchasing and advertising looks into reflected space identity through facade and theoretical factors for commercial space function, concept, merchandise and customers related facade design and makes alternative plans in order to make a better commercial space identity program.

Companies are actively engaged in various innovation activities and intellectual property rights activities such as patents in order to survive in a fiercely competitive global environment. The purpose of this study is to understand the factors that influence corporate patent-related activities on business results. For this reason, we conducted a questionnaire survey of patent practitioners and R & D personnel of Chinese companies, and analyzed the causal relationship using PLS analysis tools. As a result of the analysis, it was found that compensation and obstacle factors have a significant effect on information sharing (collaboration)... It was found that information sharing (collaboration) has a significant impact on technology complementation (improvement) and corporate image. It was also found that technical complementation (improvement) and corporate image have an impact on management results. The results of this study will be able to find and strategically utilize the factors that promote and encourage companies to develop their patent activities.

Companies are investing in CSR activities as a way to fulfill their societal obligations. It is expected that companies' CSR activities would be an effective investment to enhance corporate image, leading to consumers' purchase behavior. However, sometimes, CSR activities have a null or negative effect on the evaluation of company. The purpose of this research is to find ways to solve these problems and it reviews some research concerning donation and introduce these research into CSR. Specifically, this study examines the effect of CSR beneficiary appeals on the attractiveness of corporate identity and the mediating role of the inferred motives of CSR. The results show that consumers evaluate the corporate identity less attractive which employ the self-benefit CSR appeal. In addition, the findings also suggest that the effect of the CSR beneficiary appeal on the attractiveness of corporate identity is mediated by the inferred motives. These results suggest some managerial implications concerning communication guidelines of CSR. Specifically, companies need to communicate sincere motives of CSR rather than business.

Since the 1990s, Corporate Social Responsibility (CSR) issues have been attracting more and more attention from companies and researchers alike. The purchasing behavior of consumers is directly related to not only a company's financial performance, but also the future development of the company. Much of the previous research regarding CSR has mainly focused on the perspectives of enterprises. This paper aims to study the impact of CSR on purchase intention in three aspects - consumer, company and country. We decided to use Samsung to describe the impact of CSR on consumer purchase intentions in China. The results of this study revealed that CSR has a positive impact on the consumer-company identification, corporate reputation and country of origin image. Consumer-company identification turned out to be amore important moderator between CSR and consumers' purchase intentions than country of origin image and corporate reputation.

Mobile messenger services (MMSs), such as Kakaotalk, Wetalk, Line, and Whatsapp, are gaining popularity worldwide because of communicating with other people without any cost. We examined key antecedents of user loyalty to understand user's decision-making process in the MMS environment. To capture a long-term relationship with service providers, we posit relational commitment and user satisfaction as key predictors of user loyalty. Moreover, the effects of perceived usefulness, perceived enjoyment, and corporate image on user's decision-making processes were examined. The proposed model was tested by applying partial least squares to data from 220 experienced Kakaotalk users. The findings of this study found that both relational commitment and user satisfaction play an important role in enhancing user loyalty in the MMS context. The analysis results indicate that corporate image influences relational commitment and user loyalty through user satisfaction. The analysis results help MMS providers establish management or marketing strategies to effectively improve user loyalty.

Social media is drawing attention among companies for its potential as a marketing tool. There are many types of social media and their characteristics are varied, and thus choosing the appropriate social media considering the purpose of the company is important. In this paper, we conduct comparative analysis on the popular social media such as Facebook, Twitter, Naver blog, Youtube, Cyworld and Me2day using multidimensional scaling method. The result shows that there are differences in the effectiveness of enhancing diverse dimensions of corporate image among social media. This result can be used in developing social media based marketing strategy.
