This study explored the efficient hierarchical data structure of mobile interfaces. The first experiment demonstrated the effects of grouping(clear/unclear), depth level(2/3/5), and the number of items(32/64/128) on the search time and the number of errors. The results indicated that participants spent less time and made fewer errors to perform the task when the clear mobile interfaces, low depth level, and fewer items were provided. In addition, the results indicated that there were no effects of the depth level and the number of items on the search time and number of errors in clear mobile interfaces conditions. As depth level and the number of items changed, on the other hand, participants spent longer time to complete the task and made more mistakes in unclear mobile interfaces conditions. The second experiment investigated the effects of grouping(clear/unclear), the number of items(32/64/128), and spacial cues(colors/ windows/ number of cues) on search time and the number of errors in hierarchical data structures which had five depth levels. The results indicated that participants spent less time to complete the task and made less errors in a mobile interface when grouping is clear and the number of items are fewer. The results were identical with the first experiments. In addition, the main effect of spacial cues indicated that providing spacial cues via pictures and numbers can be helpful to reduce errors in search behaviors.

This study focused on shape attributes in a basic study that identified infographics expression diversification and delivery efficiency based on formative attributes. To achieve that goal, formative attributes were categorized as geometric or expressional type, and significant differences between them were found by identifying the attributes of each type. The study analyzed the correlations between each infographic type's formative attributes and content delivery. The results found that regularity, clarity, visibility, and content delivery were attributes of the geometric type, whereas expressionality, visibility, clarity, and content delivery were attributes of the expressional type. Further analysis of the attributes focusing on content delivery found that regularity and visibility significantly influenced content delivery for the geometric type, and expressionality and clarity significantly influenced content delivery for the expressional type. Thus, this study empirically confirmed that formative attributes of infographics distinguished between expression types with statistically significant differences during the visualization process. And that specific factors influencing content delivery were formative attributes.

Some clauses of the prior review rules for broadcasting commercials, which are enforced by the Broadcasting Act violate the right to free speech guaranteed by the Constitution. The range of prohibited expression under the clauses are too vague and overbroad to distinguish between permissible and impermissible broadcasting commercials. The clauses also fail to pass the constitutional principle that restrict government from excessive regulation on constitutional rights. The principle has a four-pronged test on the government action; 1) the validity of its goal; 2) availability of appropriate means; 3) necessity of infringement; 4) and balancing test of interests. Some clauses of the prior review rules that forbid expressions on sensitive political and cultural issues fail to pass none of the four-pronged standards.

The mutual relations and equivalence between the boundary conditions for electromagnetic waves are discussed in terms of a waveguide step. In order to verify our approach, the reflection characteristics of a rectangular waveguide step are compared with respect to the boundary conditions. The characteristics of a rectangular waveguide step are analyzed with a mode-matching technique. In order to verify our approach, convergence behaviors and electromagnetic distributions are shown.

This study was to find out that the effects of emotional clarity and perspective-taking on communication of married persons targeting 206 peoples. It set the clarity of emotional recognition and perspective-taking as the independent variables and the communication as the dependent variable and verified them. The results revealed in this study are as follows. When looked at the correlation between the clarity of emotional recognition, perspective taking, and communication of married people, each variable showd close correlation. It showed that the communication of married people had a statistically significant effect to the clarity of emotional recognition and perspective taking through the multiple regression analysis. As above, the result of this study confirmed the clarity of emotional recognition and perspective taking as factors that affect to the communication. It confirmed that more positive and reasonable communication is possible when understand the emotion clearly and the perspective taking which is the ability of standing in other people's perspectives.

The purpose of this study is to examine the relationship between rejection sensitivity and reactive aggression among college students, as well as to determine the mediating effects of self-concept clarity and hostile attribution bias on the relationship between rejection sensitivity and reactive aggression. A self-report questionnaire was conducted online for the purpose of gathering data from university students aged 18 years and older. A total of 250 participants were included in the analysis. SPSS 27.0 was used for data analysis to check the basic statistics of the variables, frequency analysis, reliability analysis, and correlation analysis. In addition, the model fit was checked using Amos 21.0, and the bootstrapping method verified the significance of the indirect effect. The results of this study are as follows. The results of this study are as follows. First, rejection sensitivity positively affects reactive aggression through self-concept clarity. Second, rejection sensitivity increases the hostile attribution bias, leading to an increase in reactive aggression. Third, rejection sensitivity positively influences reactive aggression in an indirect way by sequentially affecting self-concept clarity and hostile attribution bias. These findings have implications as they identify psychological factors that affect reactive aggression in college students. This suggests the importance of utilizing psychological interventions to address reactive aggression associated with social problems, such as crime, and provides a foundation for both treatment and prevention. Finally, implications for further research and limitations of this study are suggested.

This study examines how preference clarity and customer participation levels affect evaluation of fit toward customized services and also analyzes the effects of cultural difference between Korea and China that may cause variance in the evaluation of fit in the course of interaction with the prior two factors, preference clarity and customer participation level. It conducted a $2{\times}2{\times}2$ between-subjects factorial design adopting preference clarity, customer participation level, and difference of culture. The subjects were composed of 200 Korean and 200 Chinese. According to the analysis results, it is revealed that Korean consumers highly perceived fit toward customized services when their preference is clear and participation level is high, and they evaluate fit more favorably as participation level increased, while Chinese consumers' evaluation for fit deteriorated as participation level increased. The result shows that fit evaluation became more positive through participation when preference clarity is high in Koreans but not in Chinese.

Preannouncing a new product to its target audiences has been more and more prevalent in a wealth of industries, particularly industries that attach great importance to the speed of entry. Grounded in market signaling theory, the current research advances a theoretical model that takes full cognizance of the relation between preannounced information about an upcoming product and individual customers' behavioral intentions as well as significant moderating effects of prior product knowledge and new product innovativeness. In response, a web-based survey is conducted for data collection and the structural equation model is utilized for data analysis. Results of this study demonstrate that preannounced new product information attributes (i.e., quantity, clarity) may positively influence consumers' attitudes, in turn, lead to a favorable purchase intention. Moreover, the moderating effects of product knowledge and product innovativeness are also confirmed. Specifically, product knowledge moderates the quantity-attitude relation positively and moderates the clarity-attitude relation negatively, whereas product innovativeness does opposite. Both implications and limitations are also described.
