This research explores a value chain structure of VR-AR media including user's perception, uses, and evaluation. The purpose of this research focused on factor analysis and the relationship among user's VR-AR adoption motivations and utilities. This research explores correlation between personal value and using motivation. This study was to identify the value structure of respondent on VR-AR usages based on means-end chain theory. The research used structured APT laddering questions and 251 data was analysed. Through such analysis, category difference by stage and relationship difference were identified and hierarchical value map was compared. There are four different value ladders: first is attributes, functional consequences, psychological consequences, and final value. This study is based on the analysis of the value chain structure factors that affect VR and AR use behavior (attributes, functional benefits, psychological benefits, use value), 'Hierarchical Value Map' between users' The purpose of the model is to construct a model. For this, 'means-end chain theory' was applied to measure the causal relationship between personal value and VR related use behavior. In order to solve this research problem, 135 people were analyzed through the structured questionnaire using the AR and VR content fitness measure and the second APT laddering, and the use of VR-AR : 1) Functional benefits; 2) Psychological benefits; 3) Means to reach value, 4) Objective value chain structure was identified. The results show that VR users tried to smooth the social life through the new virtual reality audiovisual element, the newness of experience, fun, and pleasure through the departure of reality, vividness of experience, and leading fashion. The AR fitness was a game and a new program, and the value of interacting with other people and the value of 'periwinkle' played an important role through the vividness and peripheral interaction of AR, It was an important choice. The important basic values of users' VR and AR selection were correlated with psychological attributes of interaction with others, achievement, happiness and favorable values.

In this study, in order to analyze the preference for UAM of public transportation users following the introduction of urban air transportation(UAM), A preference consciousness(SP) survey was conducted on 840 users of Incheon public transportation using the Incheon International Airport-Incheon Gil Hospital route, which is the urban air traffic(UAM) demonstration route section. In addition, the means selection model was estimated based on the results of conducting a preference consciousness (SP) survey. As a result of analyzing the time value for travel using the established means selection model, it was found to be 56,428 won/hour, As a result of verifying the elasticity of travel cost (won), in-vehicle time (minutes), and out-of-vehicle time (minutes) in the model, the effect on the urban air traffic (UAM) share in this model was found that travel cost (won), in-vehicle time (minutes), and out-of-vehicle time (minutes) were in order, and the effect was greater when the travel cost (won) decreased than when it increased.

Due to the recent technological improvements, the environments of e-books and its contents have been changed and the users of e-books have drastically increased. This study aimed to propose a model on how children access and search e-books in this digital era. For this study, a potential model was proposed based on the analyses on various information-seeking behavior models. For analyzing children's access and search processes on e-books, 30 children in five public libraries or school media centers in Seoul and Kyoungi-do areas were recruited for the in-depth interviews. As a potential model on children's access and search on e-books was re-visited and revised based on the results, a cyclic model of children's access and search on e-books was proposed containing six factors.

This study examined the importance of independent variables that affect users' preference on the VODs of the newly-released movies by using the conjoint analysis. The results demonstrated that 'price(44.6%)' is the most important variable, which is followed by 'device(24.5%)', 'recency(18.0%)', 'producing country(12.9%)'. Respondents obtained the relatively high utility from watching the VOD of a Korean movie currently on screen in 3,000 wons. A television set was the most preferable device for watching VODs. The traditional windowing strategy in the media content market has been recently challenged by the new trend that the holdback period between market windows is ignored and the high-priced content is found in the second window. Nevertheless, this study demonstrated that users of the VODs of the newly-released movies are still very sensitive to the price and consider 'the recency' to be relatively less important than 'price'.

Smartphone users select restaurants using restaurant recommendation apps and use previous visitors' reviews as key decision-making information. It has not been studied yet how users react to negative reviews and how their reactions lead into the dining decision. In this study, we examined whether there are differences in the influence of negative reviews on intention to visit the restaurant according to users' decision making styles. This study confirmed negative reviews affect user decision differently according to three attributes (food, service, and atmosphere), and also partially verified that the effects of negative reviews are different according to decision-making style.

The South Korean government is looking for a solution to the ever-growing problems of traffic congestion, and surging international oil prices: the use of the humble bicycle to get to places. However, Many people feel inconvenient using bicycle because of the insufficient bicycle infrastructure and lack of the safety and connectivity between existing pathways. In this study, bicycle level of service model using ordered probit model is developed considering safety, convenience, connectivity, and factors that affect bicycle LOS. The ordered probit model would be recommended for the research which relates in choice, preference and strength etc. Bicycle level of service criteria is calculated by applying this model reflecting bicyclist's point of view. The model which develops from this research which accomplishes a bicycle level of service evaluation and represent alternative solution to encourage bicyclist. It is believed that the proposed model would be greatly utilized in bicycle network planning, bicycle road and facility alternatives testing, projects funding priority.

R-tree is index structure which is frequently used for handling spatial data. However, if the number of dimensions increases, or if only partial dimensions are used for searching the certain data according to user preference, the time for indexing is greatly increased and the efficiency of the generated R-tree is greatly reduced. Hence, it is not suitable for the multidimensional data, where dimensions are continuously increasing. In this paper, we propose a multidimensional hash index, a new multidimensional index structure based on a hash index. The multidimensional hash index classifies data into buckets of euclidean space through a hash function, and then, when an actual search is requested, generates a hash search tree for effective searching. The generated hash search tree is able to handle user preferences in selected dimensional space. Experimental results show that the proposed method has better indexing performance than R-tree, while maintaining the similar search performance.

The lack of an understanding of the characteristics and searching abilities of a specific user group in computer-based information systems in libraries hinders library and information science professionals in making the best decisions when designing, acquiring, and managing information systems. The objective of this study was to provide information on the characteristics and searching abilities of specific groups such as Korean college students & ones who study abroad, male & female, undergraduate & graduate students, etc. This study also has focused on the methods of loaming to use OPACs and non-user study. Questionnaire was administered to both Korean college students in the city of Taegu, Korea and students who study abroad in the state of Texas, US.A. 345 usable questionnaires were obtained and analyzed. These were analyzed using descriptive, inferential statistics, multiple correlation, and SPSS software. The. major findings of this study are: (1) There was a significant difference among specific student user groups except undergraduate and artiste-athlete students in the distribution of their knowledge about how to use OPACs: (2) There was a significant difference among specific groups in the means of their knowledge: (3) There was no significant difference among un. groups in the distribution of loaming method to use OPAC systems : (4) The correlation between the number of searching methods that the respondents knew in using OPACS and the amount of using computers (0.6635) is comparatively higher than my other correlation to the searching methods. Also, years of experience using computers, frequencies of computer use, and frequencies of OPAC use are comparatively higher than frequencies of library use and frequencies of manual card catalog un: (5) Frequencies of manual card catalog use have low negative correlations with the number of searching methods that the respondents knew in using OPACs: (6) Frequencies of manual card catalog use have little if any negative negative with OPAC and computer use. Conclusions are drawn from the findings in this paper, and recommendations an proposed when designing, adopting, or managing a new system. Topics fur future studies on the characteristics of OPAC systems and their use are also suggested.
