This paper proposes the new aided inertial navigation system. This system has two states, the one is attitude state and another is position and velocity state. For compensating IMU sensor errors, each two state use different filter, the attitude state use EKF and the position state use UPF. This method makes estimating position faster and more accurate.
The Reversed Effects of Advertising of Socially Controversial Products on Endorsers
황서영,문정훈,임현주,정재석 한국마케팅학회 2017 ASIA MARKETING JOURNAL Vol.19 No.2
This study investigated the impact of advertising of socially controversial products on its endorsers and products, and the role of media in moderating the results. Using the source credibility model with 174 survey samples, advertising of controversial products as a form of product placement (PPL) was found to have negative impact on consumers’ attitude toward the endorsers. The results also confirmed that the moderating effect of media credibility on consumers when developing perceptions toward the endorsers. The results suggest marketing managers to use endorsers with careful consideration in designing advertising messages for socially controversial products, especially when delivered as a product placement on television.

Objective: PD-1 inhibitors have demonstrated improved health outcomes in cancer patients. PD-1 inhibitors are well-tolerated and associated with immune-related adverse events. The objectives of this study are to analyze use patterns of PD-1 inhibitors in patients with cancer and to investigate the incidence of thyroid-related adverse reactions in patients treated with PD-1 inhibitors. Methods: The study included patients who had been administered PD-1 inhibitors (either nivolumab or pembrolizumab) at the Samsung Medical Center between October 1, 2016 and June 30, 2017. Data was collected from electronic medical records and tested using Mann-Whitney tests and Chi-Square tests for statistical significance. Associations between PD-1 inhibitors and incidence of adverse events were tested using Cox regression for age, gender, BMI, ECOG PS and medication. Results: Two hundred fifteen patients were identified as eligible for analyses. Thyroid-related adverse events occurred in 20% of patients (n=43). Thyroid function tests (TFTs) was performed in 109 patients (50.7%). Positive results of PD-L1 testing were found in 53.2% of the 94 patients who had the test. Approved doses of nivolumab (3 m/kg) and pembrolizumab (200 mg) were administered in 70.4% and 53% of patients, respectively. The analysis of risk factor of thyroid-related adverse reaction did not show statistically significant differences (Cox regression). Conclusion: Thyroid-related adverse events are common in patients treated with PD-1 inhibitors and hypothyroidism is the most frequent adverse reaction. Routine TFTs monitoring is strongly recommended to evaluate thyroid function in real-world clinical practice.
