The purpose of this study was to measure using a six-step solution for taste recognition threshold and using a Wet-Test for salivary flow amount of the adults who reside in Daegu area and are more than their 40's old to find out the relationship between DMFT index and OHIP-14. The study result revealed that the practice of oral health gave an effect to taste recognition threshold, dietary habit gave an effect to salivary flow amount, and sweet and sour taste of taste recognition threshold and salivary flow amount gave effects to the DMFT index. Therefore, it was found that the person with good practice of oral health and dietary habit had good taste, salivary flow amount and DMFT index. According to this result, it is necessary to increase the practice of oral health, increase the sensitivity to taste recognition threshold, improve dietary habit, increase salivary flow amount and decrease DMFT index in order to improve OHIP-14. Dietary habit education has been performed without the evaluation on the individual's level of taste recognition threshold. Therefore, it is necessary to develop the education program to measure and notify the taste recognition threshold in the oral health education so that individual can adjust it by himself.

With the development of the Internet and the spread of mobile devices, the online market is growing rapidly. As the number of customers using online shopping malls explodes, research is being conducted on the analysis of usage behavior from customer data, personalized product recommendations, and service development. Thus, this paper seeks to analyze the overall process of online shopping malls through process mining, and to identify the factors that influence users' purchases. The data used are from a large online shopping mall, and R was the analysis tool. The results show that customer activity was most prominent in categories with event elements, such as unconventional discounts and monthly giveaway events. On the other hand, searches, logins, and campaign activity were found to be less relevant than their importance. Those are very important, because they can provide clues to a customer's information and needs. Therefore, it is necessary to refine the recommendations from related search words, and to manage activity, such as coupons provided when customers log in. In addition to the previous discussion, this paper proposes various business strategies to enhance the competitiveness of online shopping malls and to increase profits.

The rapid increase of Passenger cars which is caused by the discomfort of Public transit and the Preference of automobiles is the major factor of increasing traffic congestions in Seoul With the point that leading the automobilists to the Public transit can be the most important Policy to ease these traffic congestions, this study focuses on the behavioral aspects of company employees and university students and investigates factors influencing bus ridership. To be brief, by estimating bus ridership through count models, this study investigates factors which influence bus ridership and elicits Political suggestions which lead automobilists to Public transit. The Purpose in this study is the application of appropriate count data model. The count data models have been widely applied to the economic area from the middle of the 1980s and to transportation aspect mainly in the foreign countries from the latter half of the 1980s. Even though a few studies in this country employed count data model to count data. all of them were Poisson regression models without suitable tests for the importance of the model specification. In the end, as the result of statistical test, negative binomial regression model which is suitable for overdispersed data was found to be appropriate for the data of weekly bus ridership. To emphasize the importance of model specification, both of poisson regression model and negative binomial regression model were estimated and the results were compared.

In the knowledge and information-based age of today, it would be fair to say that the compatibility of each person, enterprise, and nation can be evaluated by how each of them manages and maintains the knowledge created from data and information. Since the importance and necessity of knowledge management has been acknowledged, there have been studies to create, apply, and evaluate the knowledge concerning design. Previous studies done on this subject can be divided into three main categories - CRM, online statistical research, and eCRM - according to the materials used to create knowledge. These studies are meaningful in that they can create knowledge in their respective fields, although they are somewhat inadequate because the designers can't create as much knowledge as can be applied in business; design-related consumers demand composite knowledge integrating the characteristics of all three fields. In other words, they want to know the ordinary customers'preferences in the previous off-line market in the CRM field, the research results of statistical questionnaires to the various elements of design in statistical research fields, and even the pattern of preference and consumption of many and unspecified persons transcending the time and place in eCRU field. This study proposes to solve the problem related with web-based design knowledge maintenance through the synthetic application of CRM, Statistical Research, and eCRM The information proposed in the solution can De expected to help designers working at design-related enterprises, as well as research institutes, to develop the knowledge necessary to design more consumer-oriented products.

Objectives: This study was performed to investigate the relationship between individual-level social capital and depression. And, we assessed if depressive symptom mediates the relationship between social capital and self-rated health status. Methods: Data from the 2011 Community Health Survey were analyzed for this study. We used chi-square tests and analyzed a four step approach in which several regression analyses were conducted and significance of the coefficients was examined at each step. Results: In men, the results of controlling mediating factor (depression): social participation was not significantly associated with self-rated health status(p=0.082), the finding supports that social participation was fully mediated by depression. In women, the relationship between social capital(trust, social participation) and self-rated health status was partially mediated by depression. Conclusions: In order to increase self rated health status, not only improvement in trust and social participation are needed but effort to reduce depression must be combined.
