Trust is one of the most important aspects of the relationship between retailers and consumers in e-commerce. Users may have concerns about transaction security or personal information leakage when they engage in transactions over the Internet. It can be difficult to attract customers if the retailers or service providers cannot establish trust with their customers. There have been many studies of trust-building mechanisms between customers and e-storefronts. However, little work has been done on identifying the relationships between customer satisfaction, purchase intention, and trust. In addition, trust building occurs in the pre- and post-purchase phases of an e-commerce transaction, as well as gradually over repeated transactions. Thus we distinguish between cue-based trust and experience-based trust. The objective of this study was to explain the impact of trust on customer satisfaction and purchase intention in relation to e-commerce sites from the perspective of a multi-dimensional concept of trust. We surveyed 350 undergraduate students and obtained 331 responses for analysis. The result of our analysis showed that cue-based trust has a positive relationship with trust based on experience. Although the two concepts of trust have positive relationships with satisfaction, the path coefficient of trust based on experience was higher than that of cue-based trust. In addition, the purchase intention mediates the relationship between cue-based trust and experience-based trust.

We deal with the headway which effects on the performance of the PRT(Personal Rapid Transit) system and the system safety. The headway, time between passage of one vehicle and the next, is one of the important factors to assess the line capacity, which has a cue to solve the problem of the congestion in public transportation. To decide the headway there are many important factors, especially such as the failure vehicle deceleration rate, the following simple analytical equation can be made to assess the relation between the line speed and the minimum headway. In this paper we employ a numerical analysis method using a simple analytical equations for the evaluation of the minimum headway and show simple simulation results.

The main purpose of this study was to investigate preschoolers understanding whether thinking influences emotion with cognitive cueing. The subjects were 75 preschoolers of the J, Y, & K kindergartens located in Taegu. They were 4-(12 boys and 13 girls), 5-(12 boy and 13 girls), and 6-years(13 boys and 12 girls) old. The instruments were 4 stories and 11 pictures per a story used in Lagattuta, Wellman & Flavell(1997). The responses given from preschoolers were classified in terms of cognitive cueing response. The major results showed that an initial understanding of cognitive cueing in some preschoolers revealed the evidence of significantly developmental changes during the preschool years. Cognitive cueing responses were significantly different according to thinking prompt which is the question to help preschoolers explanations. This result suggested that the instruments of measurement for preschoolers should be improved as possible as they can understand.

Advanced online environment and communication technology have made the e-commerce environments evolved rapidly. In the e-commerce area, one of the most important concepts regarding the relationship between seller and buyer is the "trust." Considering the purpose of purchase and satisfaction of website, the users may face problems such as consumer's transaction security or personal information sharing when they make transactions over web sites. It could be difficult to pursue the goal for the users to purchase product or service over online if the seller or service provider cannot establish trust to the customers. In this paper, through multi-dimensional viewpoints of trust, satisfaction can be accounted for by cue-based trust and experienced trust. The purchase intention mediates the experienced trust when online users purchase products or use online service.

Mobile phone devices and memory card can be robbed and lost due to the carelessness that might be caused to leak personal information, and also company's confidential information can be disclosed. Therefore, the importance of user authentication to protect personal information is increasing exponentially. However, there are the limitations that criminals could easily obtain and abuse information about individuals, because the input method of personal identification number or the input method of password might not be safe for Shoulder Surfing Attack(SSA). Although various biometric identification methods were suggested to obstruct the SSA, it is the fact that they also have some faults due to the inconvenience to use in mobile environments. In this study, more complemented service for the user authentication was proposed by applying Keystroke method in the mobile environments to make up for the faults of existing biometric identification method. Lastly, the effectiveness and validity of this study were confirmed through experimental evaluations.

Typically users prefer to manage and access personal photo collections taken from a cell phone based on events. In this paper we propose an event clustering algorithm that requires low computation cost with high accuracy supporting incremental operation. The proposed method is based on the statistical analysis of the elapsed interval of intra-event photos on the real sample data for the decision of an event boundary. We then incorporate both location and visual information for the ambiguous range to split with only temporal cue. According to test results, we show higher performance compared to existing general clustering approaches.

The purchase-related responses of MZ generation consumers may vary depending on the environmental factors of the fitting room. Therefore, this study extracted and systematized fitting room characteristics in the retail fashion environment. In-depth interviews were conducted with a total of 50 informants to collect data on the experience of using the fitting room. Then, a qualitative analysis was performed. First, results confirmed that the environmental factors of the fitting room include physical (spatiality, functionality, comfort, and convenience) and human (interactivity and congestion) aspects. Next, additional analysis was performed on functionality and interactivity to clarify the influence of environmental characteristics of the fitting room. These factors were classified into qualitative categories. The study results confirmed that, in the case of functionality, preferred lighting and mirror factors vary depending on the clothing product type, the place and situation for wearing, and individual characteristics. Furthermore, regarding interactivity, the preference for the presence of sales staff or companions differed according to personal traits and the need for additional information and evaluation. The study provides valuable information for effective fitting room space planning for offline fashion stores to meet the needs of MZ generation consumers.

Objectives : Autobiographical memory (ABM) is a special type of episodic memory, containing events that have occurred in a personal life. Overgeneral tendency of ABM refers to the retrieval of memory with only general and categorical descriptions rather than specific events. ABM specificity in depression and posttraumatic stress disorder is a robust finding with relation to cognitive vulnerability, affect regulation, problem-solving ability. It is also implicated in bipolar disorder with frequent relapses. In this study, we investigated whether ABM specificity was related to manic or euthymic mood states in patients with bipolar disorder. Methods : Forty bipolar patients with manic and euthymic episodes and 25 healthy controls participated in this study. Prompted by 5 positively and 5 negatively valenced emotional cue words, each participant was instructed to recall positive or negative memories and describe them in detail. The One-way ANOVA was used to compare ABM scores and post-hoc analyses were done. Results : Comapred to the healthy persons, the bipolar patients reported significantly more general than specific negative memories in both manic and euthymic episodes (p = 0.003). However, there was no significant difference between manic and euthymic patients (p = 0.074). Conclusions : These results suggest that overgeneral tendency of negative ABM may be a trait abnormality in bipolar disorder. Moreover, this phenomenon might be related to underlying cognitive deficits or affect regulation irrespective of the mood state.

Test situations are relatively specific and are experienced by everyone. The major purposes of this overview are to review the current concepts and theories of test anxiety and based on this review to suggest future directions in test anxiety theory and research. Test anxiety can be explained in terms of drive-oriented approach. trait-state anxiety theory, cognitive theory, cognitive and emotional approach, and psychodynamic theory. Usually, high test-anxious students keep the following characteristics : 1) The test situation is seen as difficult, challenging and threatening. 2) The individual sees himself as ineffective, and inadequate in handling the task at hand. 3) The individual focuses on undesirable consequences of personal inadequacy. 4) Self-deprecatory preoccupations are strong and interfere or compete with task-relevant cognitive activity. 5) The individual expects and anticipates failure and loss of regard by others. Future directions in test anxiety research should be focused to elucidate the nature and construct of test anxiety and the etiological factors of test anxiety by conducting research on the relationship between parental or social attitude and test anxiety. The effects of test anxiety on memory, attention, and cue utilization should be performed to elucidate the relationship between test anxiety and performance.
