With the development and widespread application of online shopping, the number of online consumers has increased. With one click of a mouse, people can buy anything they want without going out and have it sent right to the doors. As consumers benefit from online shopping, people are becoming more concerned about protecting their privacy. In the group buying scenario described in our paper, online shopping was regarded as intra-group communication. To protect the sensitive information of consumers, the polynomial-based encryption key sharing method (Piao et al., 2013; Piao and Kim, 2018) can be applied to online shopping communication. In this paper, we analyze security problems by using a polynomial-based scheme in the following ways : First, in Kamal's attack, they said it does not provide perfect forward and backward secrecy when the members leave or join the group because the secret key can be broken in polynomial time. Second, for simultaneous equations, the leaving node will compute the new secret key if it can be confirmed that the updated new polynomial is recomputed. Third, using Newton's method, attackers can successively find better approximations to the roots of a function. Fourth, the Berlekamp Algorithm can factor polynomials over finite fields and solve the root of the polynomial. Fifth, for a brute-force attack, if the key size is small, brute force can be used to find the root of the polynomial, we need to make a key with appropriately large size to prevent brute force attacks. According to these analyses, we finally recommend the use of a relatively reasonable hash-based mechanism that solves all of the possible security problems and is the most suitable mechanism for our application. The study of adequate and suitable protective methods of consumer security will have academic significance and provide the practical implications.

Job's tears(Coix lachryma-jobi L.) chungkukjang powder and wheat bran powder were added to American cookies for practical use as healthy compounds. We examined the antioxidant activity and quality characteristics of cookies prepared with different amounts(as ratios of 10%, 20%, 25% to the flour quantity) of Job's tears chungkukjang & wheat bran powder. The antioxidant activity was estimated by DPPH free radical scavenging activity, the total phenolic compounds content and flavonoid content in Job's tears chungkukjang & wheat bran powder and cookies. The quality characteristics of Job's tears chungkukjang & wheat bran powder American cookie were estimated in terms of bulk density, pH of the dough, spread ratio, color, texture profile analysis, proximate composition, and sensory evaluations. While the spread ratio and the total polyphenol contents, flavonoid contents and DPPH free radical scavenging activity of cookies significantly increased, pH, hardness and L value of the cookies decreased with increasing Job's tears chungkukjang & wheat bran powder(p<0.01). The consumer acceptability score for the 10~20% Job's tears chungkukjang & wheat bran powder American cookie ranked significantly(p<0.05) higher than those of the other groups in texture andoverall preference. This suggests that Job's tears chungkukjang and wheat bran powder are good ingredient candidates for increasing consumer acceptability and functionality of cookies.

With widespread use of smart phones, SNS has been growing rapidly. Companies are required to do its utilization and a preemptive response. However, taking advantage of SNS is still insignificant in the companies. Compared with traditional marketing, people still consider the SNS marketing unfamiliar. This study is aimed at widening the breadth of understanding of marketing activity using SNS and inquiring into its effective applications. In an effort to achieve this research objective, first, this study analyzed the aspect of real applications by reviewing diverse practical business cases. Second, this study provided the momentum of the understanding of SNS marketing-based knowledge. The effective method of producing consumer-intimate products and services lies in customers' participation in development and production. SNS marketing is the very communication and gives ear to a customer's voice. Earnest and creative SNS marketing will play a role as a stepping-stone for businesses to move much closer to a customer.

As the overseas direct purchase market grows rapidly, firms are setting up various strategic directions to attract consumers. However, many previous researches on this issue have focused on consumption behavior based on consumers' motivation and demographic factors, so there is a certain limit to suggest practical implications for firms. Therefore, this study proposed modeling to understand how firm's strategic direction influences consumers' acceptance behavior in order to overcome these limitations. For this purpose, this study conducted a survey on 357 domestic consumers and conducted empirical analysis through structural equation model analysis. As a result, the effort expectancy of overseas direct purchase site has a strong influence on consumer intention as much as performance expectancy. We also found that product variety had the strongest impact on performance expectancy and that web site reputation directly affected consumers' behavioral intention as well as purchasing behavior.

To infer the true state of a regional product's attributes, consumers use the image they have of the product's region of origin; however, products may have multiple countries of origin in their design, branding, sourcing and manufacturing becuase more products are increasingly a result of multi-firm and multi-country efforts. We examined how the country-of-origin image (country image and product image) affect international consumers' perceived value (function value and symbolic value) and purchase intentions of made-in China goods by extending and deepening the flexible model. Second, to investigate the differences of COO effects according to different types of country-of-origin we divided the traditional country-of-origin into two components: country-of-manufacture (COM) and country-of-brand (COB). We then explore how the impact of China's country image on consumers' perceived value and purchase intentions varies when China is the COM or COB of the same product. Six hypotheses were proposed to test our anticipations. We recruited 800 Korean adult consumers who previously purchased made-in China products to participate in the online investigation. Data analyses were conducted with confirmatory factor analysis and structural equation modeling using SPSS and AMOS. The main results are discussed as follows. First, the effects of China's COO image on Korean consumers' perceived value and purchase intentions vary when China is the COM or COB of a product. Second, a positive effect of the function value and symbolic value on the purchase intentions was found. Literature and practical implications of findings are discussed and suggested in the conclusion.

On 1 July 2000, as the over-65 year-old population numbered 3,371,000 and accounted for over 7.1% of Korea's total population, an aging society was revealed. The over-65 percentage climbed to 11.0% by late 2010. A truly aged society is expected soon, by 2019. This aging society requires marketing research concerning the consumer behaviour and well-being of the elderly, because the 'silver generation' is emerging as a large part of the consumer market. The purpose of this study is to empirically analyse one effect among several satisfaction factors in the consuming cycle of various health functional products on consumer's well-being and the effect of product knowledge on the relationship between product satisfaction and well-being. To achieve this purpose, we established a research model after reviewing previous studies on product satisfaction, product knowledge, and consumer's well-being. The following hypotheses were developed from the research model. Hypothesis 1: When elderly consumers' satisfaction with health functional products increases, their well-being will increase. Hypothesis 2: The effect of their satisfaction with health functional products on their well-being will be strengthened according to the level of their knowledge of the products. Those hypotheses were tested by multiple and moderated regressions to the empirical data through a questionnaire survey. As a result, Hypothesis 1 was totally adopted, and Hypothesis 2 was only partially adopted. The study has many practical implications for well-being marketing. First, in order to heighten the elderly consumer's well-being, the level of his or her satisfaction with the health functional products has to be raised in every stage: during the acquisition, preparation, use, maintenance, and disposition of the consumption cycle. Moreover, promoting positive emotional experiences while diminishing negative ones requires effort because a consumer's well-being is made up of various needs. Second, the marketing of health functional products should be invigorated in order to raise the level of elderly consumers' knowledge of them. In other words, it is important to give them an expertise in the health functional products through different channels. A statistical analysis showed, however, that their knowledge has a decisive effect on only two satisfaction stages, preparation and maintenance. Nevertheless, this merely confirmed the intuitive assumption that the knowledge of health functional products is most relevant to their preparation and maintenance. In conclusion, this study is timely because few empirical studies exist on the relationships between silver consumer behaviour and well-being marketing. It contributes to our understanding of this subject by revealing the causality between the silver consumer's satisfaction and his or her well-being in the consumption cycle and by discovering the moderating influence of knowledge in that process.

The research purpose for The Impact of Aviation Safety over the Consumer's Behavior in Korea lies at the judgement that airline consumers' selection criteria has much changed after several serious aviation accidents as before when we used to overlook "aviation safety" variable through surveying to Korean aviation consumers and foreigners visit or travel Korea on various purposes. Therefore, for this research, practical analysis methods are employed after surveying to actual passengers who use Kimpo International Airport's international and domestic terminals. This study will be regarded significant in terms that empirical analysis was used to prove "Aviation Safety", a variable which had not been regarded as a airline choice factor within Korea air transport market so far, and has an effect on the aviation consumers' airline preference change and choice after recent frequent aviation accidents. Presenting this dissertation, I wish. it can be another opportunity for Korean two national flag airlines to reappraise and reinforce the significance of "aviation safety" and set forth immediate vigorous efforts to support the government's aviation safety improvement countermeasures. I hope the study to contribute and provide a variable idea and direction to improve aviation safety management of two Korean flag carriers.

This study aims to examine the impact of characteristics of SNS content provided by airlines on customer satisfaction and to explore the effect of the personal characteristics of the customers which have a modulating effect on the relationship between content characteristics of SNS and customer satisfaction. The data were collected over a period of April 21. 2019. to July 21. 2019. for three months from the people who have experience using SNS provided by airlines. 225 samples were selected and used as final samples from a collection rate of 93.4 percent. Findings suggest that the characteristics of airline's SNS content which include a promotion, information, and communication showed a positive impact on customer satisfaction. The analysis of a modulating effect of individual characteristics on the relationship between the airline's SNS content characteristics showed that diversity pursuit propensity, innovation propensity, and information-seeking propensity control the relationship between characteristics of airline's SNS content which are publicity, information and customer satisfaction. And it was found that all three personal characteristics do not control the relationship between communication and customer satisfaction. Thus, airlines should use SNS more effectively to generate customer satisfaction and present marketing measures to help generate profits through consumer purchasing behavior. It is expected that the findings of this study will help airlines to utilize marketing implications for effective and practical marketing methods.

In this study, the current status of product information of functional outdoor jackets in the hang-tags was investigated in perspective of consumer protection. Effectiveness and preferred alternatives to hang-tag information were also investigated. For the market survey, 1560 hang-tags from 676 functional outdoor jackets were investigated. For the effectiveness and preferred alternatives, 472 adults in their 20-60's were surveyed. The average number of hang-tags was 2.3 but 5.9% did not provide any product information. The contents included functional property of fabric; quality guarantee; brand introduction; product characteristics; instructions for care/usage; subsidiary material information, and they were different depending on end-use of jackets. Consumers strongly wanted explanations of the terms used in the hang-tag and could not accurately figure out the functions of the products from hang-tag information regardless of expression methods. The percentage of incorrect answer of 'figure/foreign language' method was extremely high. It is a noticeable feature of graph method that customers perceived that the graph was difficult to understand, but the percentage of correct answers was much higher than other methods, implying that graph method was possibly more useful at delivering accurate information to the customers who pursuit information. Customers strongly agreed to need of alternative methods and preferred an unified performance grade from selected functions based on the end-use of products. Customers also wanted to include the information of performance change after laundering. The results could provide practical insights to the consumers, companies, and the government to prepare proper guideline/policies for consumer protection.

In addition, an intense competition depending on the diversity of consumer demands women's clothing brands show changes in market organization such as diversification of the circulation market and general market depression in this rapidly changing fashion environment. Companies tend to use fashion VMD (a marketing-strategic approach) as a differentiation method to create a fashion brand shop image as brand differentiation becomes difficult due to generalization of techniques. This study analyzes forms and types of VMD recognized by consumers within this marketing communication environment and Q methodology was adapted to analyze the subjective internal order of individuals. First, a set of stimuli that presented the brand name and another without it were prepared (two sets in total) to examine the effects in the presentation of the brand name. Stimulants with the brand name were presented to the subjects by the same method after an experiment through stimuli without the brand name presented. As a result, VMD recognition factors were classified into 4 Q factors in cases of stimuli without brand names and 2 factors in cases of stimuli with brand names. This indicates that among brand functions, the role of simplifying information management and grasping the thoughts of consumers was applied. This study has a practical value of presenting VMD directions of each brand image based on the factors discovered.
