Data Security is the most challenging area in Internet communication, where most of the secret sharing schemes are proposed for binary images. But still it lacks in providing security for data communication, especially in image transmission. Traditional visual cryptography scheme generate meaningless diwies and the reconstruction phase leads to quality degradation over the secret image. In this work, an intelligent two dimensional secret share construction scheme is proposed. A secret image is expanded into n diwies with the choice of scheme selection. By Stacking all the qualified diwies to revert the secret image without content loss and less than s^* - 1 shares could not reveal any information about the secret image. The experimental results emphasize that the proposed secret share scheme is highly secured for image transmission.

In this study, an efficient removal algorithm for specular reflections in a tooth color image is proposed to minimize the artefact interrupting color image segmentation. The pixel values of RGB color channels are initially reversed to emphasize the features in reflective regions, and then those regions are automatically detected by utilizing perceptron artificial neural network model and those prominent intensities are corrected by applying a smoothing spatial filter. After correcting specular reflection regions, multiple seeds in the tooth candidates are selected to find the regional minima and MCWA(Marker-Controlled Watershed Algorithm) is applied to delineate the individual tooth region in a CCD tooth color image. Therefore, the accuracy in segmentation for separating tooth regions can be drastically improved with removing specular reflections due to the illumination effect.

Purpose: This study investigates the direct effect of service innovation and corporate image on distribution of behavioral intention and the mediating effect of customer satisfaction on these relationships. Research design, and methodology: The study was conducted through using a questionnaire as a research tool. The data were collected from 444 banking customers who used mobile banking services in Thailand. The data were analyzed through using the structural equation model (SEM). Results: The results demonstrated that service innovation and corporate image had a statistically significant effect on distribution of behavioral intention. Customer satisfaction did not mediate the relationship between service innovation and distribution of behavioral intention. On the other hand, it was found to mediate the link between corporate image and distribution of behavioral intention partially. Conclusions: These results emphasize the significance of strategic marketing practices in shaping customers' perceptions of organizational image, which can subsequently influence their satisfaction with the services. Furthermore, this study highlights the role of service innovation in creating perceived values for customers, leading to a positive attitude toward the services and a higher intention to use them.

The purpose of this study was to analyze the signification system between logo and brand image systematically in imported fashion luxury brands through semiotic approach. For this purpose, 29 luxury brands were selected from 3 department stores. According to the visual characters of logo, the types of logo used in the imported fashion luxury brands were classified into three types and the results of this study were following : First, the luxury brands used the brand logo in common that represent the name of founder or fashion designer to deliver the character of company's own brand and to emphasize the spirit of a craftsman. Second, the luxury brands also used the brand logo that design the brand initial in symmetry of the right and left or top and bottom to emphasize a unique spirit of the brand. Third, the luxury brands used the brand logo that represent or symbolize a specific animal or object to express the special quality of the brand in descriptive type. Forth, the luxury brands used the most frequently black color in brand logo that symbolize a perfection, immortality and solemnity, etc.

Purpose: This study is designed to explore web-site service quality factors in job information site for high quality human resource, and to test relationship among web service quality, image, user satisfaction, relationship quality, and loyalty intention. Methods: A survey tool was questionnaire that had obtained validity and reliability through literature survey and pretest survey, and sample 214 was analyzed through SEM using SPSS21.0 and AMOS21.0. Results: Web design and information offer affect Image and user satisfaction. Also, relationship quality turned out to be an important mediator between image and loyalty intention and between customer satisfaction and loyalty intention. Conclusion: This study shows that two factors in via of relationship quality, were important factors that related companies have to emphasize to raise performance, Also, in order to raise loyalty intention of customer, marketer should exert to well manage relationship quality having significance as a mediator.

This study proposes a deep neural network model based on an encoder-decoder structure for visual dialogs. Ongoing linguistic understanding of the dialog history and context is important to generate correct answers to questions in visual dialogs followed by questions and answers regarding images. Nevertheless, in many cases, a visual understanding that can identify scenes or object attributes contained in images is beneficial. Hence, in the proposed model, by employing a separate person detector and an attribute recognizer in addition to visual features extracted from the entire input image at the encoding stage using a convolutional neural network, we emphasize attributes, such as gender, age, and dress concept of the people in the corresponding image and use them to generate answers. The results of the experiments conducted using VisDial v0.9, a large benchmark dataset, confirmed that the proposed model performed well.

In societies emphasizing the importance of youthful appearance, attitudes toward aging are closely related to how individuals perceive their own bodies, which can be a major determinant of psychological well-being among older adults. The purpose of this study was to examine the associations between attitudes toward aging, positive body image, and life satisfaction among older Korean adults, based on relative deprivation theory and social identity theory. Employing an online survey questionnaire, data was collected from 408 Korean aged 65 and over. The proposed research model was examined via partial least square structural equation modeling (PLS-SEM). Results revealed that higher levels of psychosocial loss were associated with lower positive body image, while higher levels of physical change and psychological growth - a good example were associated with higher positive body image. Higher levels of positive body image were associated with higher life satisfaction. Overall, positive attitudes toward aging may increase positive body image and life satisfaction among older adults, controlling for subjective financial and health status. The results of this study emphasize that we should not overlook the importance of positive body image in psychological well-being among older adults.

The purpose of this thesis is to study the aspects of sex identity in the contemporary mens fashion expressed through sexual image and taste in the half of twentieth century. The aspects of sex identity expression in the contemporary mens fashion can be classified by image, that is, homosexual, heroic, bisexual, and fetish. 1. The homosexual image has shown the tendency to emphasize the masculinity since 1950.60s. It can be found in \"Cowboys costume\" which is typical of American traditional fashion, and jeans and underwear fashion expressed by muscular men has homosexual characteristics which contain narcissism. 2. Based on mens traditional gender role, the heroic image emphasizes mens physical characteristics and expresses tough and offensive masculine beauty in mens suit which is free from the authority and formality. 3. The bisexual image denied the division of gender role by costume and destroyed the traditional sex model by resolutely applying womens costume such as skirts to mens fashion. 4. The fetish image is similar to bisexual image in that they wear womens costume, but different in that it expresses sexual desire or fantasy. It is expressed through brilliant color, leather and metal ornaments, and sensual element of women which emphasizes \"body\". This shows the sex identity of contemporary men who want more sensible and free life.sible and free life.
