Purpose: This study aims to examine the effect of SNS, an important advertising means of airlines, on advertising attitudes and brand change behavior. It is intended to present practical implications by empirically analyzing demographic differences according to the source of SNS information acquisition. Research design, data and methodology: The questionnaire was revised to the contents of this study based on previous studies. It was conducted from June 15 to September 15, 2021. 297 copies were confirmed as valid samples and empirically analyzed. The proposed model was analyzed through path coefficient estimation. Results: SNS advertisement content has a positive effect on advertising attitude and brand change behavior. Advertising attitude has a positive effect on brand change behavior and has a mediating effect between advertising content and brand change behavior. There was a difference according to the source of information acquisition. Conclusions: This study suggested that when airlines engage in advertising using SNS, knowing and utilizing SNS content should be considered very important for airlines because it affects advertising attitudes and brand change behavior differently. This study is meaningful in that it can present the characteristics of SNS contents that can enhance advertising attitudes and brand change behavior when conducting marketing using SNS.

The purpose of this study was to examine the relationship among infants' nonverbal communication, maternal verbal behaviors and the infants' acquisition of vocabulary. The subjects were 93 pairs of 10 to 18 months old infants and their mothers residing in the Seoul and GyeongGi-Do area. The results were as follows : (1) In terms of the infants' nonverbal communicative means, it appeared that the group of 16~18 month olds utilized more gesture and vocalization. As regards the infants' nonverbal communicative functions in terms of social behavior and joint attention, the group of 16~18 month olds was found to perform more of the behaviors from this category than the other groups. There was a significant difference in the maternal verbal behavior among the different age groups. (2) Among the infants' nonverbal communicative means, gesture and vocalization, there appeared to be a significant relationship between vocalization and the infants' acquisition of vocabulary. In addition, there was an important relationship between the high usage of infants' nonverbal communicative functions with behavior regulation and the high usage of joint attention and the successful acquisition of vocabulary among infants. (3) Social play, which is a maternal verbal behavior categorized as one of the strategies for getting infants' attention, was significantly related to the acquisition of infants' vocabulary. (4) When mothers used more imitating sounds and mimetic words, requests for information, descriptions, conventional social expressions, and imitation to enhance responsiveness, infants were found to have acquired a larger vocabulary.

In this paper, we propose the information acquisition and analysis system for a vehicle driver in order to provide the safe driving environments. We first define the list of reckless driving behaviors and propose the recognition system, which recognizes the reckless behaviors, by using the acquired information. The collaboration among the information acquisition, the analysis, and the behavior comparison modules increases the accuracy of the recognition rate. Our system alarms to a vehicle driver in order to notify the potential to confront the dangerous situation due to the abnormal or reckless driving behaviors.

This study examined awareness and information acquisition behavior regarding food hygiene and safety of university students to improve safe dietary practices and to get basic information to develop educational materials for food safety. It was conducted among 276 university students of Qingdao University and Liaocheng University in Shandong province, China through a self-administered questionnaire. Data were analyzed by SPSS Windows V.19.0. To describe characteristics of the respondents, frequency distributions were used. In addition, t test, one-way analysis of variance and Duncan's multiple range tests were conducted. The results were as follows: The respondents were generally interested in food hygiene and safety. However, the level of awareness regarding the food hygiene and safety system in China was not high. Almost forty-five percent of the respondents did not think that foods produced and distributed in China were safe. For the reasons for their distrust, most of the students replied that they did not trust the safety 'because of distrust for hygiene of the food process', followed by 'because of distrust for food distribution' and 'because of excess or illegal use of food additives on food process'. The respondents answered for the concern level toward food hygiene and safety foodborne disease threatened food safety the most, followed by heavy metal contamination and endocrine disruptors. The respondents acquired most information from electronic media including TV and radio. Most of the students wanted to participate in food hygiene and safety education. Finally, when they found hazardous or foreign materials in food the most frequent reaction was 'paying attention in the next purchase', followed by 'notifying others', and 'letting it go this time but never buying that product in the future'.

In this Paper new results relating to the acquisition behavior of a class of first-and secondorder digital phase-locked loops (DPLL) originally proposed by Reddy and Cupta are presented in the absence of noise. It has been found that the number of quantization levels L and the number of phase error states N play important roles in acquisition. For a given L-level quantizer, as N increases, the acquisition time increases, and the lock range decreases. However, the deviation of the steady state phase error decreases in this case. When L increases, the acquisition time decreases, and the lock range increases. However, variation of L affects little for the steady state phase error. In addition, the effects of a loop filter on acquisition have also been considered. One can get smaller acquisition time and larger lock range as the filter parameter value becomes larger. However, deviation of the steady state phase error increases in that case. Analytical results have been verified by computer simulation.

This study investigated information acquisition from hypertext and the difference of searching behavior between adults and children. In experiment 1. we compared the amount of information acquisition from the hypertext to that of the printed text. The result showed that the performance in printed text was better than in hypertext. However. the performance of experienced (in the internet) participant showed no difference between the hypertext and the printed text. Experiment 2 compared the information-searching behavior of the adults and children in the hypertext environment. The results showed that adults performed the information-searching faster than children, yet there was no difference in the proportion of correct responses of the two groups. However. children who were more experienced in the internet and produced right answers to the 7th level questions in depth performed better and faster than the adults who were not. These results suggest that the experience in the internet is the most important factor in the searching of the wanted information.

BACKGROUND/OBJECTIVES: The expansion of menu labeling to restaurants has created a need to study customers' behavior toward nutrition information. Therefore, the purpose of this research was to compare college students' behavior toward nutrition information communication between Korea and the US. This study consisted of three objectives: 1) to compare the frequency of usage as well as degree of trust regarding smartphone-based communication channels in the acquisition of nutrition information among college students between Korea and the US, 2) to compare knowledge-sharing behavior related to nutrition information among college students between Korea and the US, and 3) to identify the role of country in the process of knowledge-sharing behavior. SUBJECTS/METHODS: A survey was distributed via the web to college students in Korea and the US. Data were collected in the 2nd week of March 2017. Completed responses were collected from 423 Koreans and 280 Americans. Differences between Koreans and Americans were evaluated for statistical significance using a t-test. In order to verify the effects of knowledge self-efficacy and transactive memory capability on knowledge-sharing behavior related to nutrition information, a regression analysis was performed. RESULTS: Significant differences were found in the frequency of usage as well as degree of trust in communication channels related to nutrition information between Korean and American college students. While knowledge self-efficacy and tractive memory capability had positive effects on knowledge-sharing behavior related to nutrition information, country had a significant effect on the process. CONCLUSIONS: This study is the first to compare customer behavior toward nutrition information acquisition and sharing between Korea and the US. Comparative research on nutrition information revealed differences among the different countries. Therefore, this study contributes to the body of knowledge on the nutrition information research, in particular, by providing a comparison study between countries.

Surveillance systems play a pivotal role in ensuring the safety and security of various environments, including public spaces, critical infrastructure, and private properties. However, detecting abnormal human behavior in lowlight conditions is a critical yet challenging task due to the inherent limitations of visual data acquisition in such scenarios. This paper introduces a spatiotemporal framework designed to address the unique challenges posed by low-light environments, enhancing the accuracy and efficiency of human abnormality detection in surveillance camera systems. We proposed the pre-processing using lightweight exposure correction, patched frames pose estimation, and optical flow to extract the human behavior flow through t-seconds of frames. After that, we train the estimated-action-flow into autoencoder for abnormal behavior classification to get normal loss as metrics decision for normal/abnormal behavior.
