This paper describes a new approach that can extract the relative shift vectors between two aerial image sequences for implementing the visual navigation system. This method minimizes the noise included in the aircraft attitude information that represents the changes of the aircraft attitude using the statistical method and Kalman Filtering method. This result can be used to find the relative shift vectors which are independent of the attitude changes indicating the true trajectories of aircraft. We applied this method to the image about which we had already known the information of aircraft attitude, and that result showed that the errors were minimized successfully.

Because of consistent growth of the outdoor-wear market, many outdoor wear brands have implemented diverse marketing strategies to catch consumers' attentions. This research was started with a purpose of examining sponsorship marketing and its effects on outdoor-wear brands. Future research should be conducted by modifying and supplementing the points that were not considered in this study. The factors used to analyze the effects of sponsorship marketing on outdoor-wear brands were brand attitude and purchase intention, and the study used questionnaires collected from 396 men in the Daegu-Gyeongbuk Province. Analysis of the data was performed using factor analysis, independent sample t-test, ANOVA, and cluster analysis. The study result is as follows. First, there was no difference in sponsorship-marketing attitude, brand attitude, and purchase intention according to the level of information consistency. Second, there was a significant difference in sponsorship-marketing attitude, brand attitude, and purchase intention according to age, income, clothing expenditure, and spending for products. Third, there was no difference in sponsorship-marketing attitude, brand attitude, and purchase intention according to the shopping orientation group.

Supporting communications among users, Social Network has encouraged various information flows through relationships among them. This paper studies on mentality or attitude of Social Network Services (SNS for short) users, on the basis of Technology Acceptance Model (TAM for short) and then proposes so-called TAMS, Technology Acceptance Model for Social Network Services. SNS users make full use of SNS as channels in order to create, expand, and obtain some information related to personal concerns. We will research on how the benefits that users get by using SNS exert influence on user-perceived usability. The SNS-using benefits focus on relationship benefits that are formed by interactions among users. Provided that perceived usability affects mental or informational benefits according to involvement of SNS users, we will check how perceived usability or ease of use is connected to brand attitude.

This paper presents the attitude algorithm using Fuzzy technique to mix gyro information with accelerometer. The attitude angle calculated by the low-cost gyros only increases its error with time rapidly because of the integration process of the algorithm and large sensor error. It is known that the accelerometer output includes the attitude information of a vehicle and its information is more effective during low dynamic maneuver. Therefore it is needed to combine two information appropriately for obtaining the attitude information from low-cost MEMS inertial sensors. Because Fuzzy logic is very effective to make a decision of maneuvering state, it is applied to the mixed algorithm. It is shown by experiment ...

This study analyzes factors that determine the usage of digital information by senior consumers in the mobile environment. Senior consumers are alienated from digital information in South Korea; therefore, there have been increasing attempts to resolve this digital divide and reduce the digital information usage gap between young adults and senior consumers. The study used panel data from the National Information Society Agency (2017); there were 1,463 participants, aged 50-79 years. SPSS 19.0 was used to conduct the statistical analyses for frequency, factor analysis, Cronbach' ${\alpha}$ analysis, descriptive analysis and hierarchical multiple-regression analysis. The results are as follows. First, negative attitude toward information society negatively influenced the mobile digital information usage in diversity context. Second, average monthly income, degree of digital device usage motivation, positive attitude toward digital device usage, digital literacy of PC & Mobile, and family support positively influenced the mobile digital information usage in diversity context. Third, negative attitudes toward information society negatively influenced the mobile digital information usage in quality context. Forth, average monthly income, degree of digital device usage motivation, positive attitude toward digital device usage, digital literacy of PC & mobile, and family support positively influenced the mobile digital information usage in quality context. The study results can help further understand mobile usage behaviors among senior citizens and the implications on their quality of life in the digital information era.

The purpose of this study was to investigate the effect of attitude towards parent brand on extended fashion products in case of fashion brand extension. The subjects of this study were 386 college students and data were collected using survey questionnaire. For data analysis, factor analysis and path analysis were applied. The results showed that there were four factors (e.g., familiarity attitude, emotional attitude, value-expressive attitude, utility information attitude) in attitude towards parent brand and six factors (e.g., economical risk, utilitarian risk, social risk, psychological risk, time/advantage loss risk, risk for losing opportunity) under perceived risk in extended product. The results showed that attitude towards parent brand had a negative effect on perceived risk in extended products and had a positive effect on attitude towards extended products. Perceived risk in extended products then had a negative effect on purchase intention of extended products whereas attitude towards extended products had a positive effect on purchase intention of extended products.

With precise GPS carrier positioning result, we can get attitude information if GPS antenna has adequate attaching position on the vehicle. In this case, baseline length information can be bandied as an additional measurement or constraint. In this paper, we have proposed a method to improve the attitude accuracy. To overcome nonlinearity of baseline observation model, we analyze attitude estimation result using existing estimation method like a least square method and Kalman filter, and apply a new nonlinear estimation method an unscented Kalman filter Finally we confirm the improvement of attitude estimation result in the case of appling the unscented Kalman filter.
