The purpose of this study was to test the hypothetical model designed to explain nursing students' perceived stress, coping levels, and stress outcomes. This hypothetical model was based on the Kim. Jung Hee(l987)' s stress model and stress-related literature. Exogenous variables were self-efficacy. hardiness. social support. and exercise. Endogenous variables were stress perception. coping levels. and stress outcomes. Empirical data for testing the hypothetical model consisted of 205 nursing students. SAS PC Program and LISREL 8.12a program were used for descriptive statistics and linear structural relationship(LISREL) modeling. The results were as follows. 1) The overall fit of the hypothetical model to the data was good( $x^2$=78.41(p=0.010), $x^2$/ df=1.50. RMSEA=0.05, standardized RMR= 0.05, GFI=0.95, AGFI=0.91, NNFI=0.90, NFI=0.94). 2) The results of statistical testing of the hypotheses were as follows. (1) As expected. self-efficacy had a significant effect on stress perception. But. hardiness. social support, and exercise did not have a significant effect on stress perception. Self-efficacy, hardiness. social support, and exercise explained 12% of the total variance of stress perception. (2) As expected, self-efficacy, hardiness, social support, exercise, and stress perception had a significant effect on coping behavior, Self-efficacy, hardiness, social support, exercise, and stress perception explained 53% of the total variance of coping behavior. (3) As expected, stress perception and coping behavior had a significant effect on stress outcomes. Stress perception and coping behavior explained 84% of the total variance of stress outcomes. In conclusion, the hypothetical model of this study was confirmed in explaining and predicting stress perception, coping levels, and stress outcomes in nursing students. And these findings suggest the need to develop nursing intervention to enhance self-efficacy, hardiness, social support, and exercise to decrease the harmful outcomes of stress.

Price is a product attribute, which is determined by the function of the producing cost and profit. It is also identified as one of the most important components of the marketing mix. For consumers, price is an always-existing cue, definite evaluation criteria, and easily accessible information in the purchasing process. Considering the concept of the clothing-price in a comprehensive perspective encompassing economic, psychological and marketing perspectives, a theoretical model was developed. The model includes souses and dimensions of price perception and related behaviors. Souses of price perception were: the actual retail price at selling point, the internal reference price and external reference price. The dimensions of price perception included sacrifice perception, economic value perception, inference, savings perception and price as information perception. Clothing price related behaviors that flowed these dimensions were: low price consciousness, value for money consciousness, price-quality inference, price-prestige inference, sale proneness and price mavenism. An empirical study was conducted to validate the theoretical model. A questionnaire was developed and data were collected from 680 adult women living in Seoul, Korea. Confirmatory factor analysis as well as exploratory factor analysis results showed that theorized price related behaviors were successful classifications.

The purpose of this study was to investigate the change of perceptions of students', parents', teachers' on creativity and character education at the model school for creativity and character education. This study used pre and post tests to examine the effects of creativity and character education on students, parents, and teachers. The results were as follows. Firstly, operating model school for creativity and character education brought about the statistically meaningful changes of students' perception on creativity and character education. However, the changes seemed that the level of their perception on creativity and character education was not rational as the average is about 3.5 point. Secondly, operating model school for creativity and character education brought about the statistically meaningful changes of parents' perception on creativity and character education. However, the changes seemed that the level of their perception on creativity and character education was not rational as the average was about 3.5 point like their children. thirdly, operating model school for creativity and character education brought about the statistically meaningful changes of teachers' perception on creativity and character education. The changes seemed that the level of their perception on creativity and character education was rational as the average was about 4.5 point unlike their students and school parents. Fourthly, it seemed that the perception on creativity and character education showed a difference among students, school parents, and teachers.

As students can purchase textbooks online or from local bookstores, we proposed a model to study the predictors of textbook purchasing from online bookstores based on the theory of reasoned action (TRA) and technology acceptance model (TAM). The survey instrument consisted of 51 items to assess 10 constructs of the proposed model, where the items used to measure the constructs were adapted from previous literature. Pre-testing and pilot testing of the measures were conducted by selected users of online bookstores. Data were collected from 220 university students who have purchased and intend to purchase their textbooks from online bookstores. The findings of this research are summarized as follows. First, navigation, previous experience, and innovation have a significant impact on the buyer's perception of ease of use. Second, price and delivery services have a significant impact on the buyer's perception of usefulness. Third, the perception of ease of use also has a significant impact on the buyer's perception of usefulness. Fourth, the perception of ease of use, perception of usefulness, and subjective norms all significantly support the purchasing intention in the case of online bookstores.

Due to Thailand's nuclear energy public acceptance problem, the understanding of nuclear energy public perception was the key factor affecting to re-consideration of the nuclear energy program. Thailand Institute of Nuclear Technology and its alliances together developed the classification model for the nuclear energy public perception from the big data comments on social media using Facebook using deep transfer learning. The objective was to insight into the Thailand nuclear energy public perception on Facebook social media platform using sentiment analysis. The supervised learning was used to generate up-to-date classification model with more than 80% accuracy to classify the public perception on nuclear power plant news on Facebook from 2009 to 2022. The majority of neutral sentiments (80%) represented the opportunity for Thailand to convince people to receive a better nuclear perception. Negative sentiments (14%) showed support for other alternative energies due to nuclear accident concerns while positive sentiments (6%) expressed support for innovative nuclear technologies.

This paper discusses how to effectively guarantee the coverage and connectivity quality of wireless sensor networks when joint perception model is used for the nodes whose communication ranges are multi-level adjustable in the absence of position information. A Connect Coverage Algorithm Based on Joint Sensing model (CCAJS) is proposed, with which least working nodes are chosen based on probability model ensuring the coverage quality of the network. The algorithm can balance the position distribution of selected working nodes as far as possible, as well as reduce the overall energy consumption of the whole network. The simulation results show that, less working nodes are needed to ensure the coverage quality of networks using joint perception model than using the binary perception model. CCAJS can not only satisfy expected coverage quality and connectivity, but also decrease the energy consumption, thereby prolonging the network lifetime.

This study aims at establishing a digital signal processing technique to control 3-D sound localization, especially focusing our ores on the role of information provided by Head-Related Transfer Function (HRTF). In order to clarify the cues to control the auditory distance perception, two conventional models named Hirsch-Tahara model and auditory parallax model were examined. As a result, it was shown that both models have limitations to universally explain the auditory distance perception. Hence, the auditory parallax model was extended so as to apply in broader cases of auditory distance perception. The results of the experiment by simulating HRTFs based on the extended parallax model showed that the cues provided by the new model were almost sufficient to control the perception of auditory distance from an actual sound source located within about 2m.

This study was intended to investigate the influences of consumer's self-monitoring, pioneer brand awareness, types of endorsers on quality perception of "me-too" brands with a focus on outdoor brands. The design of this research was comprised of 2 types of self-monitoring(high vs. low), 2 types of pioneer brand awareness(high vs. low), 2 types of endorsers(professional expert vs. typical consumer). The study was carried out by using samples from residents of Seoul and Gyeonggi area. The number of subjects used in the final analysis totaled 243, with age of the consumers ranging grom 20's to 50's. The results of this study were as follows. Self-monitoring, pioneer brand awareness and types of endorsers had shown a statistically significant correlation effect on the quality perception of me-too brands. Especially, in the high-level self-monitoring group, the effect of pioneer brand awareness on quality perception of me-too brand was significant when typical consumer model was given. The result presents that using a professional expert model in the market rather than a typical consumer model can offset the quality perception of pioneer brand with low awareness.

We propose a pattern classification model using a selective perception ability of human beings. Generally, human beings recognize an object by putting a selective concentration on it in the region of interest. Much better classification and recognition could be possible by adapting this phenomenon in pattern classification. First, the pattern classification model creates some reference cluster patterns in a usual way. Then it generates an SPM(Selective Perception Map) that reflects the mutual relation of the reference cluster patterns. In the recognition phase, the model applies the SPM as a weight for calculating the distance between an input pattern and the reference patterns. Our experiments show that the proposed classifier with the SPM acquired the better results than other approaches in pattern classification.

Virtualization technology has been widely applied in the area of computer security research that provides a new method for system protection. It has been a hotspot in system security research at present. Virtualization technology brings new risk as well as progress to computer operating system (OS). A multi-level perception security model using virtualization is proposed to deal with the problems of over-simplification of risk models, unreliable assumption of secure virtual machine monitor (VMM) and insufficient integration with virtualization technology in security design. Adopting the enhanced isolation mechanism of address space, the security perception units can be protected from risk environment. Based on parallel perceiving by the secure domain possessing with the same privilege level as VMM, a mechanism is established to ensure the security of VMM. In addition, a special pathway is set up to strengthen the ability of information interaction in the light of making reverse use of the method of covert channel. The evaluation results show that the proposed model is able to obtain the valuable risk information of system while ensuring the integrity of security perception units, and it can effectively identify the abnormal state of target system without significantly increasing the extra overhead.
