The present study investigated the impact of users' perceived benefits on their happiness and loyalty towards the university's online class system. Furthermore, the notion of loyalty was delineated into cognitive, emotional, intentional, and behavioral loyalty, and a systematic analysis was conducted to assess their respective impacts. The analysis was conducted using survey data obtained from a sample of 298 college students who possessed prior experience with the university's online class system. The analysis of the survey revealed that the satisfaction with the online class system was positively influenced by perceived practical benefits and symbolic benefits. However, it was found that emotional benefits did not have a statistically significant impact on satisfaction. Furthermore, it has been demonstrated that cognitive loyalty exerts a substantial beneficial impact on emotional loyalty, as well as a sequential and considerable positive influence on active and behavioral commitment inside the online class system established through perceived benefits. This study holds significance as it conducted an empirical analysis on the impact of users' perceived benefits of the university's online class system on their satisfaction levels, as well as its influence on the four-stage development process of loyalty.

The design of children's hospitals is highly dependent on color schemes. As a space shared together by both adults and children, the design of children's hospitals require color coordination that takes account of the users' characteristics. However, because the majority of prior research on color perception has focused overly on the emotional aspects, there is a necessity for more rational and scientific analyses to identify the characteristics of the visual perception of colors. Adopting this perspective in analyzing the characteristics of the visual perception of colors, this study aims to move beyond the abstract to focus on more objective methods, such as eye-tracking experiments, to examine the characteristics of hospital visitors' visual attention with respect to colors. Visual perception tracking experiment was conducted on the 2 chosen experimental images with a target group made up of adults and children, the following results were found. Firstly, spaces created with the preference colors of the different groups were found to develop a characteristic of developing higher attention. Secondly, observing the common tendencies for attention for adults and children, the highest region for visual concentration was formed towards the middle, as attention progresses to lower stages visually focused area changes in the order of upper-middle, left and right, and lower regions and edge regions show characteristics of not triggering attention Thirdly, it is understood that children's level of attention drops a lot faster than adults when identifying space therefore it is suspected that children need more elaborate color coordination than adults.

SNS uses the Internet as its base. It is created in order to achieve communication between the users. Up until now, most previous research were focused on the users of SNS. But, there are still a great deal of people who do not use or discontinuously use SNS. This is because users have natural resistance against SNS when using the service. In this study, time shortage perception, awareness of SNS, self-efficacy, suitability, information quality of SNS, subjective norm and privacy concern are considered as influence factors by previous research. An empirical study for Chinese students and internet users was conducted to identify how these factors influence perceived risk and perceived usefulness, and how this influence to user's resistance. This study can explain the reason why users don't use SNS and resist SNS use.

This study examines primarily the effects of perceived risk and scarcity massage on consumers in CATV homeshopping. For consumers, the perceived risk is the cause of delaying purchase decision in CATV Homeshopping while scarcity message in the Ad facilitate purchasing intention in the CATV homeshopping. And another important characteristic of consumer which exerts impact on the response of consumer to the Ad and the product is the frequency of purchasing experience. Thus the purpose of this study is to test the effect of 3 factors on consumer's response to homeshopping Ad and product: one is perceived risk, another is scarcity message and the third is consumer's difference in purchasing. And these are defined as independent variables. The responses of the consumer, the dependent variables of this test are measured in three dimensions; 1) the purchasing intention of the product, 2) the attitude toward the Ad, and 3) the attitude toward product of the consumer. 110 housewives are sampled and assigned to 4 experimental groups. All the groups first watched a video-taped homeshopping Ad messages, and then filled up their responses on the administered questionnaire. The results of this study shows as follows: 1) Perceived risk has negative effect to consumer response. 2) Scarcity message has positive effect to consumers response. 3) But especially perceived risk has negative effect to high frequency purchasing experience group. 4) Scarcity message has also negative effect to high frequency purchasing experience group. 5) The interaction effect of perceived risk and scarcity message is most prominent to the consumers of high frequent purchasing experience.

The purpose of this study is to confirm that the user benefit criteria can be applied as the user benefit criteria of children's libraries by examining the theoretical validity of the user benefit criteria and furthermore, by clarifying and verifying the mutual relation between the user benefit criteria and the child development area. For such a purpose, this study collected data from 247 users of children's libraries in the country and collected data was analyzed using the structural equation modeling. The result of analysis is as follows. First, the relation between physical development and behavioral facilitation, emotional development and physiological maintenance, cognitive development and perceptual maintenance, and the development of social skills and social facilitation was appropriate. Second, usability, safety and diversity was valid as an index of behavioral facilitation, self-esteem, amenity and peacefulness was valid as an index of physiological maintenance, esthetic sense, dynamics and flexibility was valid as an index of perceptual maintenance, and leisure, communication and territoriality was valid as an index of social facilitation. Third, children who prefer physical development prefer the benefit of behavioral facilitation, children who prefer emotional development prefer the benefit of physiological maintenance, children who prefer cognitive development prefer the benefit of perceptual maintenance and children who prefer the development of social skills prefer the benefit of social facilitation.

The purpose of this study is to empirically identify the process of technology acceptance of the metaverse, a virtual world-based platform that has attracted attention due to the 4th industrial revolution and the COVID-19 pandemic. The technology acceptance model (TAM) was used to identify factors affecting the use of the metaverse platforms and to analyze the causal relationship among these factors. For research, a survey was conducted on ordinary adult men and women and was analyzed using a structural equation model. The study found that perceived pleasure, interactivity, self-efficacy, and social influence had a positive effect on perceived ease-of-use. Interactivity and social influence had a statistically significant effect on perceived usefulness. The relationship between perceived ease-of-use and perceived usefulness was not statistically significant, but both perceived ease-of-use and perceived usefulness had a significant effect on positively forming attitudes toward metaverse. Lastly, favorable attitudes toward the metaverse platform had a positive effect on the intention to continue using it. Through this study, it was possible to identify the factors affecting the intention to use the metaverse and to confirm the causal relationship between the factors. A deeper understanding of users may be obtained in future if the research subject can be expanded and investigated with various factors.

As the popularity of single-person media content increases, We investigated the causal relationship between perceived value and intention to recommend to others. Individuality was studied on the tendency to sensation seeking and novelty seeking, which is a tendency to take boredom sensitive to monotonous and repetitive daily routines, and novelty seeking refers to new information and stimuli. The hypothesis was that high sensation seeking and high novelty seeking would perceived emotional value, epistemic value, and economic value for a single person 's media content. Hypothesis testing was performed using multiple regression analysis using SPSS21. As a result of the hypothesis test, The novelty seeking has a positive effect on emotional value, epistemic value, and economic value. Users who want to explore and enjoy new things could perceived the emotional value of having fun, fun, and sadness through single-person content, perceived a epistemic value and enjoy new information and situations as a tool to recognize new stimuli and know what they didn't know. And it could be seen that users perceive the economic value that they can enjoy at low cost or free service. The sensation seeking has a significant effect on epistemic value, but it did not affect emotional value and economic value significantly. Those who have a high tendency to sensation seeking can perceive curiosity about one-person media contents, so that they can perceive epistemic value. However, those who feel that they have not significant influence on economic value and emotional value can easily understand that expecting one's content does not feel bored by paying for a low cost or free service.

This study aims to clear the relation between perceived risk and user's attitude and behavior toward a food service event. To accomplish this, theoretical reviews and empirical analysis were jointly carried out. For the empirical analysis, a survey was conducted from April 3 to April 6, and total 291 copies of the questionnaire were used for the statistical analysis, SPSS 15.0 and LISREL 8.30. The results of the test of the hypotheses can be summarized as follows: First, the analysis shows that there is significant difference between the perceived risk and attitude of a food service event user. The perceived risk of food service event users causes effect that is contradictory in attitude. As users' perceived risk is less, attitude improved. Second, the analysis of the relationship between user's attitude and behavior intention showed that user's attitude affected behavior intention. Therefore, under these circumstances, there should be more concern in solving perceived risk among food service event users and a special program for promoting satisfaction with an event. And food service event director should make more efforts in nutritive value, organic food, time saving, etc.
