Based on the prior study, this study established the hypothesis that academic stress would lead to employment anxiety, and verified whether self-efficacy and self-esteem have a moderating effect in the relationship between academic stress and employment anxiety and the analysis results are as follows: Employment anxiety increases as the academic stress increases, and self-esteem plays a role of moderating in the relationship between academic stress and employment anxiety, but self-efficacy has not. The results of the analysis confirmed that although self-efficacy does not play a role of moderating, employment anxiety decreases as self-efficacy increases. Self-esteem generally reduces employment anxiety, but it has shown that employment anxiety increases in academic stress situations.

Currently, existing car following models among several basic systems of advanced vehicle systems are almost developed related to the physical relation between two vehicles except for the driver's behavior or environmental factors. But the consideration of driver's character and environmental factors on driving are very essential factors for actual application. Hence, we suggested calibrating the degree of driver's discomfort on driving that is the former study to develop a new car following model of advanced vehicle to use in actuality. The degree of driver's discomfortness (Measure-of-Alarmness; MOA)is measured related to the relationship between the following vehicle and the preceding vehicle, the environmental factors and driver's characters in ubiquitous traffic. We made up questions to drivers to obtain the general and the objective measurement of driver's MOA. And the fuzzy logic model for measurement of MOA was constructed based on the results of survey. We verified the suitability of fuzzy logic model through the computation of MOA with several scenarios. And we measured the quantitative degree of driver's discomfortness on car following related to several factors which affect drivers. In accordance with this study, development of car following model applying driver's MOA will promote the actual application of advanced vehicle more effectively than the existing models. Finally, we thought the measurement of driver's MOA will be applied significantly to evaluate safety and comfort of drivers on driving.

Conventional car following models are controlled when the velocity of following vehicle is equal to preceding vehicle without consideration of relative distance. Also, since the car following models are hardly consider the driver's behaviors and the environmental factors in driving, the models can't be adopted in reality. Hence, we developed the car following model applying Human Factors to consider driver's safety and comfortness. We simulated to compare the suggested model with the existing model, GGM(General GM). As results of simulations, the GGM model followed the preceding vehicle when the velocity of following vehicle was equal to preceding vehicle without relation of relative range. The other side, when the relative range was less or over than safety range, the suggested model made the relative range equal to safety range. Accordingly, we could be sure that the model would decrease the driver's discomfort and intensify the safety on driving without unnecessary waste of road. We identified that the suggested model is more realistic than the conventional GGM model.

The aim of this study was to analyze the impacts of perceived economic instability on drinking frequency in the mist of exercising the strong social distancing in the early phase of COVID19 pandemic. The data were collected from 1,117 adults aged between 19 and 70 across the nation from May 13 to May 19 in 2020 by Embrain, an on-line research company. We used only 820(73.4%) out of 1,117 who answered that they had a drinking in 2020. Bi-variate analysis and multivariate multinomial logistic regression were performed using STATA16. Multinomial logistic regression results showed that the increase of employment instability was related to the increase of drinking frequency, whereas the increase of income instability was related to the decrease of drinking frequency. In sum, the impact of perceived economic instability during the early phase of pandemic may be presented as an increase or decrease of drinking frequency depending on the effect of employment instability and income instability.

The goal of this study is to examine the impact of self-esteem, self-efficacy, and attributional disposition on communication apprehension in college students. The research problems were verified by correlation analysis and multivariate regression analysis. A questionnaire survey was conducted on 239 college students. The findings are as follows: First, the higher level group in the self-esteem and self-efficacy have lower communication apprehension scores than the lower level group. Particularly, it is found that self-confidence in self-efficacy variables has the greatest effect on communication apprehension. Second, college students with high internal attributional disposition tend to feel less communication apprehension, while college students with high other's attributional disposition and accidental attributional disposition tend to have higher communication apprehension. Third, as a result of examining the relative effects of self-esteem, self-efficacy, and attributional disposition on communication apprehension, self-efficacy is found to have the greatest effect.

This study examines university students' reading strategies based on English proficiency and reading anxiety. A total of 86 university students participated in the study and completed two questionnaires related to reading strategies[9] and reading anxiety[10]. The collected data was quantitatively analyzed using SPSS 21. The results indicated that advanced and intermediate students preferred to use Problem Solving Strategies(PROB), whereas beginning level readers tended to use and Global Reading strategies(GLOB). There was no significant relationship between reading anxiety and reading strategies. However, there were some differences between two groups. High anxiety students preferred to use reading materials and textual clues and try to focus on their reading when they have a difficulty. Low anxiety students tended to adjust reading pace and try to focus on comprehension and reread when they lost their focus. Based on the results of the study, several implications and limitations were discussed.

The purpose of this study was to investigate the moderating effect of interpersonal contact anxiety due to COVID-19 on the relationship between eating-out motivations of Korean and Chinese consumers, dining out, and delivery-takeout. As a result of examining the moderating effect of Korean consumers' interpersonal contact anxiety, it was found that interpersonal contact anxiety had a moderating effect to weaken the positive influence of rational motivation on dining out. As a result of examining the moderating effect of Chinese consumers' interpersonal contact anxiety, it was found that interpersonal contact anxiety had a moderating effect to weaken the positive influence of rational motivation on dining out. But the positive influence of emotional motivation on dining out was increased. Also, it was found that interpersonal contact anxiety had a moderating effect that strengthened the positive influence of rational motivation on delivery, and it also had the effect of weakening the positive effect of emotional motivation on delivery. It was found that interpersonal contact anxiety had a moderating effect to strengthen the positive influence of emotional motivation on takeout.
