  • This paper proposes to improve the performance of a strap down inertial navigation system using a foot-mounted low-cost inertial measurement unit/magnetometer by configuring an attitude and heading reference system. To track position accurately and for attitude estimations, considering different dynamic constraints, magnetic measurement and a zero velocity update technique is used. A conventional strap down method based on integrating angular rate to determine attitude will inevitably induce long-term drift, while magnetometers are subject to short-term orientation errors. To eliminate this accumulative error, and thus, use the navigation system for a long-duration mission, a hybrid configuration by integrating a miniature micro electromechanical system (MEMS)-based attitude and heading detector with the conventional navigation system is proposed in this paper. The attitude and heading detector is composed of three-axis MEMS accelerometers and three-axis MEMS magnetometers. With an absolute algorithm based on gravity and Earth's magnetic field, rather than an integral algorithm, the attitude detector can obtain an absolute attitude and heading estimation without drift errors, so it can be used to adjust the attitude and orientation of the strap down system. Finally, we verify (by both formula analysis and from test results) that the accumulative errors are effectively eliminated via this hybrid scheme.

  • This study addressed the effects of environmental attitude improved using forest environmental interpretation program. While previous research has focused developing interpretation program itself, this study analyzed the effects that environmental interpretation has improved toward pro-environmental attitude. This program was designed self-guiding interpretive techniques at Mt. Palgongsan Provincial Park. Environmental attitude was measured using 12 statements which was based on fifth-graders attitude scale in U.S.A. Data were collected from 84 elementary school participants in this program. Results showed that attitude scores of participants increased toward pro-environmental attitude. Especially, three statements (interest, safe and benefits of forest) are statistically significant differences between pre- and post survey. Results can be used by outdoor educators to evaluate and plan their environmental interpretation programs and methods.

  • In the past days, most of studies about website behavior and website advertisement have been mainly focused on the effectiveness of website advertisement and advertisement attitude. But the generic model of website click behavior via website advertisement has not been made and the leading theory of that has not been existed. This purpose of this research is to explore the effects of internet advertisement in website click behavior. Specially, I deal with the influence of advertisement attributes(informativeness, entertainment, attentiveness, uneasiness, website attitude and advertising attitude) which is gradually being increased or decreased to attract the website click behavior of internet users. Added to this, it is to examine the influence of two attitudes(advertisement attitude and website attitude) as mediating variables on website click behavior. Major findings of this research are summarized as follows: First, mediating effects of website attitude and advertisement attitude were tested significantly in affecting the website click behavior by website advertisement attributes(informativeness, entertainment, attentiveness, uneasiness). Second, the website attitude was affected by website advertisement attributes(informativeness, entertainment, attentiveness, uneasiness). And the advertisement attribute(except of entertainment and attentiveness) such as informativeness and uneasiness did significantly affected in the website click behavior. Also, the website click behavior was not affected but the website advertisement attitude, however the mediating effect was tested significantly.

  • Reaction wheel shows nonlinear torque response on low-speed region due to friction. Thus precise satellite attitude control on this region is hard to achieve. Previous research tries to solve this problem, by compensating friction or applying dither command. However, due to difficulties of drag torque modeling or frequent zero wheel speed crossing, these methods are not suitable to apply on the real satellite attitude control. To solve this problem, we propose the attitude controller gain adjustment method based on the attitude error.

  • This study aimed to investigate primary students' science-related attitudes through the literature review. Ninety-four papers published in domestic science education journals, since 1990, were collected and were followed by content analysis. In this study, science-related attitude was conceptualized as attitude toward science, scientist, science-related occupations, and school science, which is composed of cognitive, affective and behavioral domains. Based on the conceptualization, the instruments used for measuring students' attitudes were analyzed. The analysis of definition of science-related attitude in the articles showed different foci on cognitive, affective and behavioral domains. To suggest the effective instruction for enhancing students' science-related attitudes, this study identified students' attitude with gender, grade, residence and achievement level. The result showed that male, urban, higher-grade and better performed students had more positive attitude than female, rural, lower-grade and less performed students. As for the factors in science-related attitude, I categorized the factors into personal, environmental and pedagogical aspects, and found that psychological elements in all domains were most influential to students' change of science-related attitudes. It is interesting to note that students showed dichotomous views about experiment and that task-oriented instruction failed to enhance students' attitude. Based on the research findings, this study suggests effective instruction for improving students' attitudes and future research for science education.

  • The purpose of this study is to find the levels of self-monitoring, self-consciousness and cosmetic attitude of female university students and to analyze the relationship between the levels of self-monitoring, self-consciousness and cosmetic attitude in an effort to strengthen external human beauty. The respondents were 264 university women attending a university Chung-Cheong Province in Korea. In this study, a questionnaire method was used. The questionnaire consisted of SMS(self-monitoring scale), the(self-consciousness scale), and a measurement of the cosmetic attitude. Earlier studies were used to create the measuring instruments with some adjustments for the purpose of this research. Factorial analysis, correlation analysis, multiple regression analysis were carried out with SPSS 18.0. The cosmetic attitude consisted of four factors, and those factors were related to self-monitoring and self-consciousness. The Four factors were happiness with change, manners to others, the instrument of change, and conformity. It was found that the cosmetic attitude reflected the personal internal mental states; hence, the cosmetic attitude was used as method to express the internal mind. Determining the correlations between self-monitoring, self-consciousness and the cosmetic attitude was useful in understanding the personal peculiarity of the cosmetic attitude. Moreover, in the cosmetic industry, it is likely meaningful to investigate the capability whether the variables of self-monitoring and self-consciousness can be applied in an effort to understand consumers' internal character.

  • This research aimed to understand selfie behavior in social networking sites (SNSs). The research was conducted on the basis of the functional theories of attitude, verified self-presentation attitude, and self-expression attitude that affect selfie behaviors (i.e., taking selfies, posting selfies, and taking selfies for fashion product exposure). The moderating effect of satisfaction toward one's appearance was identified. The participants of the study were SNS users aged 20-30 years who had posted selfies in the past month. A survey was performed using an online panel of an international survey firm. The data were analyzed using hierarchical regression analysis on SPSS 22.0. Results corroborated that self-expression attitude affected the number of selfies taken but not the number of selfies posted and those uploaded for fashion product exposure. Self-presentation attitude exerted a significant effect on the number of selfies posted and those uploaded for fashion product exposure. When satisfaction toward one's appearance was high, self-presentation attitude increased the influence of the behaviors of posting selfies and uploading selfies for fashion product exposure. Self-expression attitude also significantly influenced the number of selfies taken due to the moderating effect of satisfaction toward one's appearance. This research was made meaningful by its quantitative analysis of selfie behavior in SNSs. The results confirmed the different functions of attitudes affecting selfie behavior. With the improved understanding of selfie behavior obtained from this research, Social Media marketing may be carried out in various industrial fields in the future.

  • Purpose - This study aims to examine the effect of audience attitude toward product placement, or PPL, on product attitude and purchase intention. PPL has increasingly been prevailing in TV dramas since the revision of the Broadcasting Act in January 2010, and it is quite widespread in today's society. Therefore, this study intends to investigate how the audience would take a particular attitude toward PPL in TV dramas and how their attitude would affect their product attitude and purchase intention. Research design, data, and methodology - The sample for the current study was drawn from college students in Seoul in December 2013, as the main targets of the products and brands that were advertised by PPL are young people. The questionnaire for this study comprised nine parts, such as the knowledge of PPL, experience of PPL, TV drama watching time, impulsive buying propensity, celebrity imitating buying propensity, attitude toward PPL, attitude toward product, purchase intention, and demographic characteristics. The questionnaire items were measured by 5-point Likert scales. Whether the demographic characteristics and propensity to consume would affect PPL attitude was analyzed and how the PPL attitude would affect purchase intention through product attitude was analyzed as well. To analyze the relationship between variables, structural equation modeling analysis was performed with Amos 18.0. Results - The major findings of the study were as follows. First, whether the demographic characteristics and propensity to consume would affect PPL attitude was analyzed, and it is found that out of the demographic characteristics, only gender and knowledge of PPL exerted an influence on PPL attitude. In addition, celebrity-imitating buying propensity had an impact on PPL attitude. Second, whether PPL attitude would affect purchase intention through product attitude was analyzed by structural equation modeling. Consequently, it is found that PPL attitude impacted purchase intention through product attitude. Conclusions - The findings of the study had the following implications. First, in theoretical aspects, previous studies have proven only that attitude toward PPL influenced attitude toward product and purchase intention separately; however, the current study has investigated the mediated role of attitudes toward PPL. Second, regarding the practical aspects, as PPL attitude exercised an effect on purchase intention as well as product attitude, PPL should be utilized in a manner to stimulate the audience to take a positive attitude to it. Finally, gender, PPL knowledge, and celebrity-imitating buying orientation were identified as influential factors for PPL attitude. Specifically, female consumers showed a lower attitude toward PPL than males, and the consumers who have no knowledge showed a lower attitude toward PPL. The consumers who have celebrity imitating buying propensity expressed a higher attitude toward PPL. These factors should consequently be taken into account when PPL is planned and conducted. The current study has limitations such as the sample object, non- experimental method, and media biases. Therefore, future research should be conducted to address these limitations.
