This study began with the question: "what influence would the width of river surface have on visual preference, provided that the environment surrounding the river does not change?" to evaluate the visual preference factors of the river scenery which could vary according to the change of water level. To estimate the minimum flow needed for river sceneries, field survey of Youngsan river was carried out to collect the field data and evaluated the visual preference factors to obtain a most preferred W/B ratio. At Youngsan bridge location, the feeling of open space factors, physical characteristic factors and complexity factors appeared to have significant relations to visual preferences. At Imgok bridge location, complexity factors, aesthetic factors and physical characteristic factors have significance to visual preferences. As a result of multi regression modeling, it was found that physical factors affected visual preferences the most at urban river locations and complexity factors affected the most visual preferences at rural river locations. As a results of this study, the most preferred W/B ratio was estimated as which vary from 0.5 to 0.7 and this results can contribute to the field of river landscape design to maximize the users' satisfaction level.

This study examines the effect of social conservative values that have risen as an important factor in American politics. Focusing on the abortion issue, it discusses how the abortion issue has affected American voters' issue and party preferences and their ideological orientations. The empirical results demonstrate that the abortion issue has contributed to reinforce the existing ideological and partisan divisions, although it has not realigned them. As a consequence, the abortion issue has become a significant determinant for vote choice since 1980s. Particularly in 1990s, when the polarization among the political elites became clear, the political effect of the abortion issue appears to be more evident.

The purpose of this study is to analyze the elementary pre-service teachers' preferred strategies while they solve problems which require number sense and to study a way to improve their number sense ability based on computational thinking. In a survey with 57 elementary pre-service teachers using the instrument consisting of two different number sense components, they preferred much more the rule-based strategies to the number sense-based strategies, which was consistent with the prior studies[13][14][20]. To change this situation, we present a way to improve their number sense ability by utilizing the analyzed results and the nine computational thinking components which were suggested by CSTA and ISTE(2011).

This study intends to examine the effects of education using robot on computational thinking and attitudes according to left and right brain preference. To execute the study, 17 elementary students at A youth training center in Seoul were selected to participate in the education. And the mean difference was analyzed using matched pair t-test and Mann-Whitey U test. As a result, after participating in the education, there was some statistical significance found in the scores to test student's computational thinking, but not statistical significance on the attitudes. Furthermore, there was no significance found in computational thinking or attitude according to the left and right brain preference. The purpose of this study can be found in that it expands the understanding of education using robot by verifying the efficacy and analyzing differences according to left and right brain preference.

With the help of the advancements in information and communication, information appliances are changing. Flat panels made it possible for information appliances to become smaller in size and lighter in weight, and high end graphics provide increase in realistic and immersive use. Even with these advancements interest in design for laboratory equipment tend to only stay on a level of the exterior of the equipment, not to the point of designing the interface of display GUI. Inspired with the problem above this research would contain the preference analysis ondisplay GUI design considering the characteristics of the main users and the laboratory equipment itself. The test would be held through comparison of graphic-based display GUI and text-based display GUI and analyzing the task time and number of errors made, looking for which display GUI scientist prefer. The test results show that text-based GUI has a higher efficiency but the actual users preferred the graphic-based display GUI.

It is widely accepted that public rental housing programs affect both the allocation of resources and the distribution of welfare. This paper explains institutional arrangements of public housing program in Korea and assesses the benefits of the program. In contrast to the previous studies which employed homothetic preferences, the benefits of the public housing were estimated based on non-homothetic preferences to allow for different income effects across households. Empirical results suggest that average benefit-cost ratio of public housing program is 0.91, and hence, the deadweight loss seems to be well-contained in Korean public housing program compared to other countries. However, the distribution of the benefits reveals that the transmission of the benefits should be improved to achieve the desired goals of residential welfare for low income families.

The purpose of this study is to design and develop a alternative material recommendation system using automatic classification, based on user preference. Details of usage data by users from DREAM was analysed in order to develop the way of a method on selecting proper alternative material, and then the data by user preference were allocated under each category of 10 KDC categories. The keyword, selected from the title of users' usage data from a certain period of time, were divided into 10 subject categories and ranked by the order of frequency of appearance. Books including high frequency of the keyword in title can be selected as a preferred target for producing alternative materials. Lastly, a dynamic linkage for sharing usage data among National Library for the Disabled and other libraries is proposed to produce more proper alternative materials, based on user preference.

The global mobile Internet service market is growing very rapidly, shooing drastic increases in its sales volume. Despite this growth of the market, it has not yet reached its full-grown stage, and this calls for a study on the service preference based on the characteristics of the users. As most of the existing studies in this area have centered on its technical features, they fall short of providing to the related companies any useful data to which they can practically refer in developing the future mobile services that suit for various user needs, and making plans to increase the sales volume. Based on these circumstances, this study is to investigate how the mobile contents preference is differed in accordance with the user characteristics of the Korean and Chinese mobile Internet service users. This study is also to analyze how the relationship between the user characteristics and the preferred mobile contents types is moderated by nations, Korea and Chinese. To accomplish these research purposes, this study developed a set of research model and hypotheses based on a comprehensive review of the related studies. To prove the research hypotheses, this study conducted a survey among the Korean and Chinese nubile Internet service users and performed a variety of analyses of the data collected including the questionnaires, using the SAS version 9.

Consumers possess their own psychological distance towards products. Based on the construal-level theory, this study aims to analyze which type of advertising appeal is more effective according to psychological distance. Also this study conducts neurophysiology experiment through eye-tracker. By using eye-tracking methods, participants' responses to products was measured and analyzed accordingly. Results revealed that consumers prefer rational appeals when the psychological distance is perceived near, while emotional appeals are preferred when the psychological distance is perceived far. In addition, eye movements measured in Visit Count(VC), Fixation Count(FC), and Total Fixation Duration(TFD) showed significant difference when participants are viewing preferred and non-preferred appeals.
