Despite the gradual growth of mobile markets according to an increased mobile distribution rate, empirical studies on the mobile shopping application markets are not sufficient. From the viewpoint of a large number of purchase of brand product in department store by customers and a high growth rate of mobile shopping by means of mobile shopping, we classified a principle variable, the interactivity, into three levels and verified the effects of the interactivity on the flow, effects of the flow on the purchase intention and the control effect of purchase level. In conclusion, among the three levels of the interactivity the customer-customer interactivity and the content-customer interactivity have positive effects on the flow, but company-customer has not. On the other hand, the customer-customer interactivity and the content-customer interactivity have a positive effect on the flow. Furthermore, the flow affects the purchase intention positively. After the verification of the direct effect of interactivity on the purchase intention, the content-customer interactivity only has a positive effect on the purchase intention. Lastly, the purchase level has a control effect when the customer-customer interactivity has a positive effect on the flow.

The Electronic Shelf Label (ESL) is an alternative to the paper price label attached to merchandise shelves and is attracting attention as a retail IoT infrastructure that will lead the innovation of offline retail outlets. In general, when introducing a substitute product, the company tends to consider the financial factors such as the efficiency of the investment cost compared to the existing product or the reduction of the operating cost. However, considering only financial factors in the decision-making process, it may not properly reflect the various values associated with corporate strategy and the requirements of stakeholders. In this study, 8 evaluation items (Investment Cost, Operating Cost, Quality Level, Customer Management, Job Efficiency, Maintenance, Functional Expandability, and Store Image) based on BSC's 4 perspectives (Financial, Customer, Internal Business Process, Learning & Growth), and using AHP (Analytic Hierarchy Process) to measure the priorities of evaluation items for domestic small supermarket employees. As a result of the research, priority was given in order of Customer, Learning & Growth, Internal Business Process, and Financial aspects among the evaluation items for adopting the price label, and the electronic price label was supported with higher importance than the paper price label. In contrast to the priorities of the financial aspects of most prior studies, the items of Learning & growth and customer perspectives have relatively high priorities. In particular, respondents classified by job group, The priorities of the 8 evaluation items were different among the groups. These results are expected to provide implications for both companies (retail outlets) and ESL providers (manufacturers and service providers) who are considering the introduction of ESL.

Recently, in the process of distribution industry's growth, distribution environment is changing rapidly by appearance of new business condition and strategy of multiple store. According to the intensification of competition, recently large discount stores are developing private brand(PB) products for the purpose of product differentiation and profitability. But after the economic crisis in 1997, young housewives and salaried man's that have rational and practical buying pattern become the core consumer's in the large discount stores. Hence low price strategy is not new things for the consumer's anymore. In addition to, acquiring new consumer, many discount stores are establishing new stores at the rural area. But they undergo hardships of establishing new stores at the rural area because of disparity consumer's behavior, income level and consumption's pattern among regions. So, when they try to establish new stores, they need to know consumer's behavior at the region. Therefore the purpose of this study is to analyze preference property for the private brand(PB) of large discount stores in Gyeonggi-Do.

The 3390 million people, around 83% of the adult population in Korea use smartphone. Although the safety problem of the certificate has been occurred continuously, most of these users use the certificate. These safety issues as a solution to 'The owner of a mobile phone using SMS authentication technology', 'Biometric authentication', etc are being proposed. but, a secure and reliable authentication scheme has not been proposed for replace the certificate yet. and there are many attacks to steal the certificate and private key. For these reasons, security experts recommend to store the certificate and private key on usb flash drive, security tokens, smartphone. but smartphones are easily infected malware, an attacker can steal certificate and private key by malicious code. If an attacker snatchs the certificate, the private key file, and the password for the private key password, he can always act as valid user. In this paper, we proposed a safe way to keep the private key on smartphone using smartphone's unique information and user password. If an attacker knows the user password, the certificate and the private key, he can not know the smart phone's unique information, so it is impossible to use the encrypted private key. Therefore smartphone user use IT service safely.

The purpose of this study was to propose a method for the effective management of toothbrush contamination. Toothbrush microbial contamination was analyzed according to the duration of toothbrush use, frequency of toothbrush use per day, and toothbrush storage location. We also analyzed the microbial reduction effect of vinegar, antimicrobial mouth rinse, bamboo salt, and baking soda, which are sterilization materials that can be easily used every day. We collected 45 toothbrushes from university dormitories from May to June 2018. To determine the degree of microbiological contamination with general bacteria, coliform bacteria, and Staphylococcus aureus, bristle samples were cultured at $36^{\circ}C$ for 24 hours using 3M$^{TM}$ Petrifilm plates and then measured based on Petrifilm evaluation criteria. Toothbrush microorganisms were analyzed according to the duration of use, frequency of use per day, storage location, and effect of each sterilization material. General bacteria, coliforms, and S. aureus contamination increased with frequency and duration of use (p<0.05). In particular, S. aureus showed a statistically significant increase to 36.15 CFU/ml after 1 month, 504.23 CFU/ml after 2 months, and 2,386.67 CFU/ml after 3 months (p<0.05). We found that 1% vinegar was the most effective substance for reducing general bacteria, coliforms, and S. aureus. In addition, 1% antimicrobial mouth rinse solution applied for 5 minutes was the most effective in reducing S. aureus. It is crucial to recognize the importance of toothbrush care and store toothbrushes in a dry place and replace them periodically. We recommend use of vinegar and antimicrobial mouth rinse solution to disinfect toothbrushes. These should be applied as a 1% solution for at least 1 minute. Proper care of toothbrushes is important in maintaining oral health as well as overall health. Instructions on toothbrush care should be given when teaching children or adults how to brush teeth.

Purpose - Many variables are needed for brand loyalty such as brand attitude, brand attachment, brand love and brand commitment. Thus, we should manage these all variables successfully for strong and differentiated brand equity. This study aims to identify the process of how the brand value propositions affect the brand attitude and brand attachment. This study specially conceptualizes that not only utilitarian value and hedonic value influence the brand attitude but also hedonic value influences the brand attachment. This study focuses on the moderating role of consumer involvement such as cognitive involvement and affective involvement in the causal relationships among brand value propositions, brand attitude, and brand attachment. Research design, data, and methodology - The five hypotheses were proposed and tested in this study. Three hypotheses were about the relationship among the brand value propositions(utilitarian value and hedonic value), brand attitude, and brand attachment. The other two hypotheses were about the moderating effect on consumer involvement in the causal relationships among brand value propositions, brand attitude, and brand attachment. Research data were collected from the students of universities located in Daejeon-Si and Chungchungnam-Do. For the purpose of test the hypotheses empirically, the 208 responses were used. We utilized SPSS18.0 for statistical analysis such as reliability test, factor analysis, and regression analysis. Results - The results show that the utilitarian value and hedonic value have influence on the brand attitude positively. The results also show that the hedonic value has influence on the brand attachment positively. We found that there is a moderating effect on the cognitive involvement in the relationship between the utilitarian value and the brand attitude. However, there is no moderating effect on the affective involvement in the relationship between the hedonic value and brand attachment. In Summary, 4 of 5 hypotheses in this study were supported and 1 hypothesis was not supported. We should identify the reason why the hypothesis 5, the moderating effect of the affective involvement in the relationship between the hedonic value and brand attachment, was rejected in this empirical analysis. Conclusions - Both the utilitarian value and the hedonic value that propose a brand are important for brand attitude. Specially, the hedonic value is important for brand attachment. Companies should provide the consumers with both the utilitarian value and the hedonic value in a balanced way for their favorable brand attitude and strong brand attachment. In the retail industry, the balance between the utilitarian value and the hedonic value is important in that there are many product brands and store brands providing consumers with various benefit and values. Also, there are possibilities that the causal relationships among brand value propositions, brand attitude and brand attachment are moderated by consumer involvement such as cognitive involvement and affective involvement. Companies should understand and consider consumer involvement for their efficient and effective brand management decision making.

To analyze mobility patterns, this study used three Constraint (Capability Constraint, Coupling Constraint, Authority Constraint) models which were proposed in Dr. Hagerstrand's Time-space theory. This paper shows that three constraint models have some effects upon mobility by age. In this study, Capability Constraint means a certain special constraint that is what we can't do during proceeding basic natural urges like sleep, fare, etc. Coupling constraint is a physical one. Each person limits the action range for staying on a special place in special time. For instance, students have to stay in school so that they have mobility constraints. Authority Constraint is a social one. When we use urban facilities or traffic, we may be controlled by mobility sphere by an agreement or a social position. It is social agreement that the opening hour of a store, the time table of mass-transportation and a social positional control that the personal income, the standard of education. In this study it has been in a process of determination of the cluster number that degree of influences a social constraint to mobility. Considering the mobility constraint of characteristics of space divides urban and rural, people in urban area have higher mobility rate than in rural area. Resuets of determination of the cluster, show similar mobility pattern. People in urban area are connected verity of mobility which related to urban space structures with determination of cluste-number. That is to say, mobility patterns can be changed by space charactcristics. Constraints by sex and age are also social constraints and they are influenced by mobility patterns. For instance, females at the age of twenties have similar mobility pattern to the same age male but they have sudden changes after thirty's age. Male entertains a similar pattern without restriction of age. That is to say, management by sex as a social constraint affects mobility. To establish more realistic traffie policy, mobility formation should be reflected to the space in a view of social-behavioral science. To embody this, some problems should be investigated as follows. 1. As a problem of methodology, if sufficient samples ensured, we could subdivide clusters and could open up a new method of analyzing the mobility clusters by using the neuro-network. 2. Extracting actions connected with mobility and finding life cycle which is classified by daily cluste-characteristics, suitable counterproposal could be presented to the traific policy.

There is a growing interest in the technology transfer and commercialization both at home and abroad. Accordingly, this study looked at the concept of technology transfer and commercialization, identified the factors that should be taken into account in order to facilitate technology transfer and commercialization, and then performed a empirical analysis. As for the conventional technology transfer and commercialization, there was a tendency to limit its scope to the exploration, transfer and commercialization of technology itself. Here in this research, technology transfer and commercialization is defined the category to expand as various activities implemented in order to make sure that intellectual properties such as intangible technological developments, know-how, and knowledge are transferred between the relevant parties through a contract or negotiation, and the party to which the transfer is made can then further develop and exploit the technology into tangible products and other activities to obtain economic benefit out of that. In addition, the findings of the positive analysis of technology transfer and commercialization revealed that the focus of facilitating technology transfer has been on the technology itself, its management and securing efficiency of the systems and institutions involved in the technology transfer and commercialization. So there was lack of recognition as to the importance of financial support given to the phase of technology commercialization. This indicates that when it comes to the technology transfer and commercialization, quantitative performance has been the focus of interest such as patent application, registration, number of technology transfers, royalty, etc. So there was not enough understanding as to the issues of starting up a business, creating quality jobs through technology transfer and commercialization, which are directly related to the realization of the creative economy. In this regard, this research is expected to be used for the development for the future policies to boost technology transfer and commercialization as it suggests not only simply ensuring quantitative performance but also necessary to create the environment for the creation of the stable ecosystem for the parties involved in the technology transfer and commercialization and then to build circumstances in which creative economy can be realized.

OMTP (Open Mobile Terminal Platform) is a global forum made by telecommunications providers to promote user-oriented mobile services and data business. Devised by OMTP, BONDI is a browser-based application or a mobile web run-time platform to help widgets make good use of functions of mobile devices in a secure way. BONDI enables applications programmed with web standard technologies such as HTML, JavaScript, CSS, and AJAX to reach the internal functions of mobile devices. Since BONDI, which is not just a simple network application, can reach the internal resources of devices in standard ways, it enables the application and widgets to be developed regardless of tile OS or platform. Web browser-based widgets are vulnerable to the network environment, and their exeeution speed can be slowed as the operations of the widgets or applications become heavy. However, those web widgets will be continuously used thanks to the user-friendly simple interface and the faster speed in using web resources more than the native widgets inside the device. This study suggested a method to effectively operate and manage the resource of OMTP BONDI web widget and then provided an improved result based on a running performance evaluation experiment. The experiment was carried to improve the entire operating time by enhancing the module-loading speed. In this regard, only indispensable modules were allowed to be loaded while the BONDI widget was underway. For the purpose, the widget resource list, able to make the operating speed of the BONDI widget faster, was redefined while a widget cache was employed. In addition, the widget box, a management tool for removed widgets, was devised to store temporarily idle widgets.

Price rigidity involves prices that do not change with the regularity predicted by standard economic theory. It is of long-standing interest for firms, industries and the economy as a whole. However, due to the difficulty of measuring price rigidity and price adjustments directly, only a few studies have attempted to provide empirical evidence for explanatory theories from Economics and Marketing. This paper proposes and validates a research model to examine different theories of price rigidity and to predict what variables can explain the observed empirical regularities and variations in price adjustment patterns of Internet-based retailers. I specify and test a model using more than 3 million daily observations on 385 books, 118 DVDs and 154 CDs, sold by 22 Internet-based retailers that were collected over a 676-day period from March 2003 to February 2005. I obtained a number of interesting findings from the estimation of our logit model. First, quality seems to play a role-I find that both price levels as proxies for store quality, and information on the quality of a product consumers have, affect online price rigidity. Second, greater competition(i.e., less industry concentration) leads to less price rigidity(i.e., more price changes) on the Internet. I also find that Internet-based sellers more frequently change the prices of popular products, and the sellers with broader product coverage change prices less frequently, which seem due to economic forces faced by these Internet-based sellers. To the best of my knowledge, this research is the first to empirically assess price rigidity patterns for multiple industries in Internet-based retailing, and attempt to explain the variation in these patterns. I found that price changes are more likely to be driven by quality, competitive and economic considerations. These results speak to both the IS and economics literatures. To the IS literature these results suggest we take economic considerations into account in more sophisticated ways. The existence and variation in price rigidity argue that simplistic assumptions about frictionless and completely flexible digital prices do not capture the richness of pricing behavior on the Internet. The quality, competitive and economic forces identified in this model suggest promising directions for future theoretical and empirical work on their role in these technologically changing markets. To the economics literature these results offer new evidence on the sources of price rigidity, which can then be incorporated into the development of models of pricing at the firm, industry and even macro-economic level of analysis. It also suggests that there is much to be learned through interdisciplinary research between the IS, economics and related business disciplines.
