A new technique for Attitude & Heading Reference System (AHRS) by using sequential measurement noise covariance (SMNC) is addressed in a vibration environments in this paper. In particular, a low-cost inertial measurement unit in general diverges in the acceleration phase or vibrating environments due to inherent properties of gravity and acceleration. In this paper, by considering current and prior measurements to estimate actual attitudes and headings in a local frame, the proposed technique overcomes these problems efficiently. Finally, the performance of the suggested approach is verified by numerical simulations.

Purpose: This study was conducted to investigate the level of nursing students' knowledge, attitude and behavior toward the elderly; correlations between the variables; and the factors influencing the behavior. Methods: Data were collected by 380 nursing students using a self-questionnaire from February 13th to 24th of 2017. Data were analyzed using t-test, one-way ANOVA, Pearson's correlation coefficients and stepwise linear regression with SPSS WIN 19.0. Result: The scores of knowledge, attitude and behavior toward elderly were 11.96 points (range 0~25), 4.51 points (range 1~7), 3.48 points (range 1~4), respectively. Significant differences were found in knowledge, attitude and behavior according to volunteer experience. There were positive correlations between the three variables. Factors influencing the behavior were volunteer experiences and the attitude toward the elderly, which explained about 17.7% of total variance. Conclusion: These results indicate a need to develop the gerontological nursing education program to lead to an increase of positive attitudes including volunteer work for the elderly. Accordingly, the program will help strengthen the nursing students' positive behavior toward the elderly.

Purpose: To investigate the attitude toward death and recognition of hospice of community dwellers and to examine the differentiation between the attitude, recognition, and demographic variables. Method: This study was a cross-sectional descriptive study using a questionnaire. The Fear of Death Scale (FODS) made by Collect & Lester (1969) and translated and revised by Kim (2003) was used to measure the fear of death. The data were analyzed using SPSS. Results: The subjects were725 community dwellers, 65.8% female with a mean age of 39.9 years. The mean FODS score was 3.17 out of 5, showing a slightly high negative attitude to death. There was a statistically significant difference between the type of religion and total FODS (F=3.91. p=.02). Of the respondents, 66.5% had heard of hospice and 5.5% had received hospice care. Conclusion: Based on the study results, various types of death education program for community dwellers, including the content of hospice care, should be developed. In addition, public relations for the settlement of desirable dying culture and hospice service need to be activated.

This research is based on the concept of safety airbag to design a self-rescue system for the autonomous underwater vehicle (AUV) using micro inertial sensing module. To reduce the possibility of losing the underwater vehicle and the difficulty of searching and rescuing, when the AUV self-rescue system (ASRS) detects that the AUV is crashing or encountering a serious collision, it can pump carbon dioxide into the airbag immediately to make the vehicle surface. ASRS consists of 10-DOF sensing module, sensing attitude algorithm and air-pumping mechanism. The attitude sensing modules are a nine-axis micro-inertial sensor and a barometer. The sensing attitude algorithm is designed to estimate failure attitude of AUV properly using sensor calibration and extended Kalman filter (SCEKF), feature extraction and backpropagation network (BPN) classify. SCEKF is proposed to be used subsequently to calibrate and fuse the data from the micro-inertial sensors. Feature extraction and BPN training algorithms for classification are used to determine the activity malfunction of AUV. When the accident of AUV occurred, the ASRS will immediately be initiated; the airbag is soon filled, and the AUV will surface due to the buoyancy. In the future, ASRS will be developed successfully to solve the problems such as the high losing rate and the high difficulty of the rescuing mission of AUV.

Purpose: This study examined caregiver trainees' knowledge and attitude toward the elderly. Method: This descriptive study was conducted with a convenient sample of 119 trainees in a long-term caregiver education program at one university. Following completion of a self-reported questionnaire, knowledge and attitude were measured using FAQ1(Palmore, 1998) and a 20-item semantic differential scale(Sanders et al., 1984). The data were analyzed using descriptive analysis, t-test, ANOVA, and Pearson correlation analysis by SPSS version 12.0. Results: The mean score of respondents' knowledge and attitude toward the elderly was $13.51{\pm}2.77$ out of 25 and $81.71{\pm}20.10$ out of 100, respectively. Caregiver trainees' education level and age influenced their knowledge and attitude, respectively, toward the elderly. Conclusion: Caregiver training for the elderly should involve a well-designed education program and continuous teaching that takes into account trainee education and age.

Purpose: This study is a non-equivalent control group pre-post design, which attempted to observe the effects of Basic Life Support Education on undergraduate students' CPR Knowledge and Attitude. Methods: The subjects were 96 undergraduates in Jeonbuk. They were divided into two groups: an experimental group of 46 students and a control group of 50 students. The BLS education was given by three BLS instructors certified by the American Heart Association using a DVD. Data were collected from October 20 to November 15, 2010 and analyzed, using the ${\chi}^2$ test, t-test, and ANCOVA. Results: There were significant differences between the experimental group and the control group in the levels of CPR Knowledge and Attitude. The 1st hypothesis, that the CPR knowledge scores for the experimental group would be higher than those of the control group, was supported (F=157.58, p=.000). The 2nd hypothesis, that the CPR attitude scores for the experimental group would be higher than those of the control group, was supported (F=23.78, p=.000). Conclusion: This study showed that BLS education had a positive influence on undergraduate students' knowledge and attitudes toward CPR. We expect that BLS education will contribute to spreading knowledge of CPR and reducing mortality among heart attack victims, and we can see from this study how CPR training in combination with theory and clinical practice develops knowledge and practical ability.

Due to the increase in the use of the Internet, it is becoming more common to provide or use a social login for registering for services. Herein, the purpose of this study is to analyze the influence of security, individual innovativeness, ubiquity and brand awareness on the use of social log-in service through the individuals' attitude who have memorized various IDs and passwords by using Technology Acceptance Model (TAM). In addition, the effect of individual innovativeness on the relationship between social login characteristic factors and attitudes toward social login services are examined. Based on the statistical results, it is found that the significant factors affecting the attitude toward the social login service are the security, ubiquity, brand awareness and perceived usefulness. Moreover, the individual innovativeness is found to have the moderating effects in the relationship between the three factors (the perceived usefulness, and perceived ease of use, and security) and attitude toward the social login service. Positive attitudes increase with the usefulness, ease of using social login serive when individual innovativeness is high. On the other hand, when individual innovativeness is low, the stronger the effect of security on attitude toward the social login services. In accordance with these results, the implications and limitations of this study are discussed.

This study aims to analyze the mediating influences of resonance-based self-attitude and brand credibility in a relationship between celebrity endorser credibility and celebrity endorser congruity toward brand purchase intention in the current dynamic business environment. It employs a quantitative research method and reports on a survey, using a questionnaire, including the population of consumers of various instant coffee brands in several cities in Indonesia. The number of respondents in this study was 432 people. The analysis was performed using Partial Least Square Structural Equation Modeling and SmartPLS software. The analysis consisted of descriptive statistics, evaluation of the measurement model, evaluation of the structural model, and hypothesis testing. The results partially support the model developed. The findings suggest that the instant coffee product advertising in Indonesia needs to create brand messages focusing on the formation of resonance-based self-attitude from consumers to increase the influence of celebrity endorser credibility and celebrity endorser congruity, as well as the brand credibility towards the brand purchase intention. This study contributes to the marketing literature and the theory of planned behavior by providing empirical evidence on the relationship between celebrity endorser credibility, celebrity endorser congruity, resonance-based self-attitude, brand credibility, and brand purchase intention.

The objectives of this study were: (1) to identify differences in consumer attitudes and intentions to recycle fashion products using three types of recycling (including resale, reform, and donation), and (2) to examine the moderating effects of consumer prosocialness on the relationships between attitude and intention for each type of fashion product recycling. Men and women aged 20 years and over were recruited from a marketing research firm panel. Participants completed an online questionnaire incorporating measures for attitudes and intentions to resale, reform, and donate fashion products, prosocialness, frequency of purchasing fashion products, monthly amount of spending on fashion products, and demographic information. Data from 224 participants were analyzed using SPSS 25.0 and PROCESS macro. The results demonstrated that consumers had significantly different attitudes and intentions depending on type of fashion product recycling. Consumers had more positive attitudes toward donation compared to resale and reform types of recycling. Consumer intentions toward resale and donation were significantly higher than their intention to reform. Furthermore, this study confirmed that the attitude-intention gap in fashion product recycling can be explained by individual prosocialness. The moderating effects of prosocialness on the associations between attitude and intention to recycle were significant. The implications of increasing consumers' behavior intention to recycle fashion products was discussed and future research suggestions are provided.
