This study takes a uses and gratification theory based approach to identifying the relation between TV home-shopping channel use motivation and purchase intention. The results are summarized as follows. First, in respect of TV home-shopping channel use motivation, the analysis results reveal three factors: convenience, information seeking, and entertainment. Among these, the factor of convenience was the first in the order of importance. Secondly, 1)It is found that use motivation also has some limited influence on purchase intention. 2)Selectivity and involvement degree, the sub-categories of audience activity, are found to be the variables with the highest prediction ability, suggesting a need to give a particular attention to them. 3)In addition, viewing amount, a variable of use behavior, is shown to have a significant influence on purchase intention. The followings are the implications of the study results. First, marketing strategies that enable maximization of shopping convenience are required. Second, there is a need to approach the delivery of TV home-shopping contents as a kind of broadcasting contents on their own rather than merely a medium for selling goods.

This study investigates what older adults have image of older adult with relation to their self-identity. Fourteen participants are interviewed in this study. The main findings are as follows. Their response to image of older adult is divided in the form of 'denial' and 'accommodation' about social images of older adults. 'Denial' has 'total denial' and 'selective denial' while 'accommodation' includes 'acceptive accommodation', 'selective accommodation' and 'unwilling accommodation'. 'Total denial' indicates that the participants describe older adults very negatively, and they regard themselves as a person who is totally different from the older person they describe. 'Selective denial' represents that the participants have two types of older adults: negative and positive. They describe that they are close to the positive type of older adults themselves although they do not admit that they are older adults. 'Acceptive accommodating' does not describe older adults negatively, and they identify themselves as older adults. 'Selective accommodating' are very similar to 'selective denial' although the former differs from the latter in that they accept that they are older adults. 'Selective accommodating' also includes negative and positive types of older adults, and this type of participants admit that they are older adults, and believe that they belong to the positive type. In contrast to 'acceptive accommodating', 'unwilling accommodating' describes older adults very negatively. However, the participants belonging to 'unwilling accommodating' comes to accept that they are older adults due to irresistible realities.

Focusing on the information sender, message, channel, and receiver, the existing information theory deals with the noise, information contents, and probability of choice, which involve in the process of information transmission. In the current digital environment, besides simply conveying information itself through media, the important issue is how to efficiently convey information. Therefore, we need to analyze the theory in different perspective, and to research the Information redundancy for the methodology of information design. The redundancy causes the receiver to have attraction to the information and to reduce its contents due to its supplement and repetition. So it can play a role of efficient communication method. The concept of redundancy is applied to the communication of art such as literature, architecture, painting, and design to accomplish efficient communication. In order to get persuasive information design for the receiver's perspective we need to make use of this concept. The redundancy can be applied with the technical aspect of multimedia and Interaction, which add supplemental expression, or sort of event for the receiver's experience and memory. In the process of constructing information it can be applied with the structure of gaming redundancy, entropy, the accumulating communication code using entertaining feature, and storytelling methodology. The noise and entropy could be used for the means of making redundancy, not the obstacle to information. The redundancy gives the receiver attraction on the information and makes them have strong will of interpreting it so that the purpose of conveying information will be accomplished efficiently.

This study investigates how consumers' need for uniqueness and for self-expression have influence on their attitude towards brand webtoon contents and word of mouth intention. The results of this study shows that among the sub-dimensions of brand webtoon users' need for uniqueness, unpopular choices has a significantly positive influence on their need for self-expression, and in turn it has a strong positive impact on both attitude towards the webtoon content and intention of word of mouth. In particular, the data show that respondents' perceived perception of the persuasive intent of the brand webtoon moderates the effect of need for self-expression on the attitude towards the content. More specifically, respondents who perceive the persuasive intent in brand webtoon show a lesser degree of favourable attitude towards the content than do respondents who do report a low level of perception of persuasive intent of the brand webtoon. In sum, this study not only provides a theoretical foundation to understand how consumers perceive brand webtoons in terms of their need for uniqueness and for self-expression, but the study has implications for practitioners who are interested in using a brand webtoon for marketing.

The purpose of this study is to derive factors that affect the acceptance of digital transformation in ports and empirically analyze the impact of these factors on the acceptance of digital transformation through a survey of port workers. Additionally, we test whether acceptance attitude plays a mediating role in the relationship between these factors and digital transformation acceptance. The variables used in this study are as follows. First, knowledge, self-efficacy, and involvement were included as variables related to individual characteristics, relative advantages, complexity, observability were included as variables related to innovation characteristics, and government regulations and competitor pressure were included as variables relate to environmental characteristics, so that a total of eight latent variables were selected. The results of this study are summarized as follows. First, two variables among individual characteristics, self-efficacy and involvement, were able to confirm a positive(+) causal relationship with the attitude of accepting digital transformation, and knowledge initially expected a positive(+) causal relationship with the attitude of accepting digital transformation, but the result was a negative(-) causal relationship, so that the hypothesis was rejected. Second, among the characteristics of innovation, complexity has a negative(-) causal relationship with the attitude of accepting digital transformation, and relative advantages and technological innovation have a positive(+) causal relationship with the attitude of accepting digital transformation. Finally, among the environmental characteristics, government regulations and competitor pressure, confirmed a positive(+) causal relationship with the attitude of accepting digital transformation. In addition, it was found that the attitude of accepting digital transformation had a positive(+) causal relationship with personal acceptance and social acceptance of digital transformation.

In the w/o concentrated emulsion, the volume fraction of the dispersed is greater than 0.74 and the hydrophilic liquid is dispersed in the hydrophobic liquid of the continuous phase. The emulsion has the same appearance and behaviour as a gel. The polarity of the hydrophilic liquids and hydrophobic liquids, the pH and the ionic strength of the hydrophilic liquid are found to be important factors in the stability at the polymerization temperature such as $50^{\circ}C$. The lower the polarity of the hydrophobic liquid and the higher the polarity of the hydrophilic liquid, the more stable the emulsion. Electron microscopy studies of the hydrophilic-hydrophobic polymer composites show that the particles of polyacrylamide, the dispersed phase, are separated by he network of the thin film of polystyrene, the continuous phase. This hydrophilic-hydrophobic polymer composites show higher permselectivity to water in the mixture of water-ethanol. The pervaporation experiment shows that the selectivity of the membrane ranges between 4-40 and increases with increasing enthanol concentration in the feed. The rate of permeation decreases with increasing ethanol concentration in the feed.
