The study aims to understand how indirect hallyu experiences in the Chinese market affect Korea's national brand image and willingness to purchase Korean goods from the perspective of "content consumption" and "recognition of Korea's." To that end, a total of 178 Chinese university students in the Beijing and Shanghai regions were analyzed. According to research and analysis, the perception of indirect hallyu experience has had a positive affection not only on the Korean national image but also on the willingness to purchase Korean products. Also, the halo effect came as Korea's national image had a positive effect on quite a lot of intentions to buy Korean merchandise. The recognition of South Korea can be enhanced by the spread of hallyu, which can be a decisive gauge of a favorable impression of the country in a short time.

What strategies are used to help students understand quadratic functions in mathematics classroom? In specific, how does Chinese teacher highlight a connection between algebraic representation and graphic representation? From October to November 2009, an experienced teacher classroom was observed. It was found that when students started learning a new type of quadratic function in lessons, the teacher used two different teaching strategies for their learning: (1) Eliciting students to plot the graphs of quadratic functions with pointwise approaches, and then construct the function image in their minds with global approaches; and (2) Presenting a specific mathematical problem, or introducing conception to elicit students to conjecture, and then encouraging them to verify it with appoint approaches.

Images of tobacco retail licenses have complex unstructured characteristics, which is an urgent technical problem in the robot process automation of tobacco marketing. In this paper, a novel recognition approach using a double attention mechanism is presented to realize the automatic recognition and information extraction from such images. First, we utilized a DenseNet network to extract the license information from the input tobacco retail license data. Second, bi-directional long short-term memory was used for coding and decoding using a continuous decoder integrating dual attention to realize the recognition and information extraction of tobacco retail license images without segmentation. Finally, several performance experiments were conducted using a largescale dataset of tobacco retail licenses. The experimental results show that the proposed approach achieves a correction accuracy of 98.36% on the ZY-LQ dataset, outperforming most existing methods.

This research empirically examined changes in the images of Korea over three points in time among Japanese, Chinese, and U.S. visitors to South Korea. Between March 14 and May 31, 2005, about two to three months after the 2005 Seoul International Sports & Leisure Industry Show ended, 153 tourists from America, 129 from China, and 156 from the Japan completed the survey instrument. The results from a General Linear Model (GLM) with repeated measures showed that tourists from all three countries had more positive images after the Seoul International Sports & Leisure Industry Show than before it. It was concluded that the 2005 Seoul International Sports & Leisure Industry Show appeared to have a significant positive effect in enhancing the image of South Korea. The study suggests that an internationally significant trade Show can change the image of a tourism destination in a short time period.

Reversible data hiding enables the embedding of messages in a host image without any loss of host content, which is proposed for image authentication that if the watermarked image is deemed authentic, we can revert it to the exact copy of the original image before the embedding occurred. In this paper, we present an improved histogram-based reversible data hiding scheme based on prediction and sorting. A rhombus prediction is employed to explore the prediction for histogram-based embedding. Sorting the prediction has a good influence on increasing the embedding capacity. Characteristics of the pixel difference are used to achieve large hiding capacity while keeping low distortion. The proposed scheme exploits a two-stage embedding strategy to solve the problem about communicating peak points. We also present a histogram shifting technique to prevent overflow and underflow. Performance comparisons with other existing reversible data hiding schemes are provided to demonstrate the superiority of the proposed scheme.

Digital image watermarking techniques have been studied in various fields in order to protect the copyright of multimedia contents mostly composed by images. JPEG compression is a representative copyright attack for image watermarking. The CRT-based watermarking methods in DCT domain have been studied, because these are robust for JPEG compression attack. In this paper, we propose a new method with improved performance compared with the existing CRT based methods in DCT domain. The proposed method selects the DCT block according to the denseness at the watermark insertion phase, and iteratively adjust the CRT Conditional coefficients at the watermark extraction. This paper shows that it is more robust for the JPEG compression attacks through experimental results.

This research is to verify the effects of Korean wave image on the national image and purchase intention of Korean educational product empirically. Also, it is to find out the moderating effect of engagement when Korean wave image is affecting purchase intention of Korean educational product. In order to verify this, the questionnaires were distributed to the Chinese university students of Shandong, in China, who recognized the Korean wave, and among those questionnaires, 315 were analyzed for this research. As a result of analysis, cognitive images is found out to make a positive effects on the affective image, national image and purchase intention of Korean educational products. And affective images is found out to make a positive effects on the national image and purchase intention of Korean educational products. This result suggests that throughout the factor of Korean wave, we should improve national image and try to find ways to export Korean educational industry to China. In order to activate Korean wave image in China, the government has to review the cultural contents development policies positively like promoting Korean soap operas.

This research is an in-depth study on the differences of cosmetics advertising and brand representation between Korean companies and Chinese companies. In addition, it studies the preferences of cosmetics consumption in Korea and China. To study these topics, two major methods are applied to magazine advertising analysis and consumer research. Analysis objects are the magazine advertisements of the Korean brands Mamond and Laneige, which entered the China market more than 5 years ago; the 64 advertisements are evenly split between Koreans and Chinese. The objects of the survey are 470 females between the ages 20 and 30 (237 from Korea and 233 from China). The results were as follows. First, Chinese advertisements use intense appeal in which the types of advertisement appeal are highly preferred. Second, ordinary models are highly preferred. Second, (on the nationality of the models) Chinese and Korean models are preferred in comparison to western models. Third, (as shown in the survey) Koreans and Chinese preferred magazine advertisements with headlines and copies. Four, blue colors are commonly used in the advertisements; however, the survey shows that the Chinese consumers prefer gray colors. Furthermore, from this study, there is a significant dynamic between the brand image and consumer satisfaction as well as the re-purchase intention.

This study is intended to offer basic data for developing outdoor clothing exported to China by identifying how Chinese consumers use outdoor clothing. To accomplish the objective, a survey was conducted on 300 male and female Chinese tourists in their 10s to 40s who have purchased outdoor clothing before. As more than twice as many respondents said they wear sweatsuit or everyday clothes for mountain-climbing instead of outdoor clothing, the necessity of outdoor clothing is obviously perceived at a low level. Among them, 57.4% wear outdoor clothing as townwear in everyday lives, and other respondents are dissatisfied with the design. Thus, it is necessary to develop townwear-style design. When buying outdoor clothing, wearability was the biggest consideration. Also, the first criteria for evaluating outdoor clothing was practicality for mountain-climbing activities. The functionality of outdoor clothing they needed the most was air permeability. As for outdoor clothing top, the main inconvenience was tightness around the neck. As for bottoms, it was tightness of pants when bending knees. In terms of areas to be improved, the No. 1 was unformed design. Thus, it is imperative to develop design of diverse styles. As the Chinese outdoor clothing market has grown significantly in recent years, the following should be executed by domestic companies before advancing to the market. First, they should form Korean brand image and boost the brand awareness with various activities, amid Korean Wave. Second, they should develop preferred designs among Chinese consumers and strengthen functionality of products, based on consumer survey.
