With the advent of the 5G era, smart phones and communications network technology have progressed, and mobile short video of people's life can be made, Of the new tools of communication, at present, China's social short video industry has shown rapid development, and the most representative of the short video app is Douyin (international version: Tiktok). Under the background of Uses and Gratifications Theory, this study discusse the relationship between Douyin users' preference degree, use motivation, use satisfaction and attention intention. This study divides the content of Douyin video into 10 categories, selects the form of an online questionnaire survey, uses SPSS software to conduct quantitative analysis of 202 questionnaires after screening, and finally draws the following conclusions: (1) The content preference degree of Douyin short video (the high group and low group) is different in users' use motivation, users' satisfaction degree and users' attention intention. ALL results are within the range of statistical significance.(2) Douyin users' video content preference degree has a positive impact on users' use motivation, users' satisfaction degree, and users' attention intention. (3) Douyin users' motivation has a positive impact on users' satisfaction and user' attention intention. (4) Douyin users' satisfaction degree has a positive impact on users' attention intention. Based on the research results, we suggest that Douyin platform pushes videos according to users' preferences. In addition, as the preference degree has an impact on users' motivation, satisfaction degree and attention intention of using the platform, it is important that the platform's focus should to pay attention to the preference degree of users. Collecting users' preferences at the early stage of users' entering the platform is a good way to learn from, and doing a good job of big data collection and management in the later operation.

The purpose of this study is to analyze the change of perception and to measure the degree of interaction between the lighting and the finishing materials according to preference types and the impacted factors to the spatial sensitivity of users. To do that, the this change was grasped through the experiment with Likert Scale and ANOVA of SPSS program to the simulated images. The result of this study is as following. Firstly, the personal difference in the perception of space comes from 'attention' in information processing process. The degree of the perception of users change strongly by lighting in the space expressed the 'modern natural'. Secondly, the atmosphere and the degree of perception are different in the preference of users to the spatial sensitivity and in impacted factors which are thought by users in the space sensitives. The users who prefer the 'decoration' feel the mood more strongly in the space. But the users who prefer the 'active' and 'intimacy' are opposite to that. The difference to the degree of perception is greater in the 'classic natural' than the others under the lighting turns on. Thirdly, an in-depth research which is considered of the interaction among the various factors is needed for finding the design methods for inducing the sensitivity of users in the space. And the ranking of the impacted factors should be understanded and applied to the research regarding the changes of perception in the space. Finally, this study has the limitation to be adapted to all of the situation for the space design methods. But this will be a basic data to study the design methods for users's sensitivity in the space.

The purpose of this study was to present data to the landscape planning and design through analyzing correlation between visual preference of users and nonusers and the landscape of hole in golf couses. Stimulus objects were selected from the 18 holes in Tae-gu Country Club. Preference value was judged through photo simulation by 35 subjects photographed at Tee and Interpoint (IPI, IP2), and classified into three landscape types and nine landscape components from photo analysis by researcher. For test of difference between groups toward each stimulus, t-test was used, and Duncantest, Correlation analysis for finding out correlation between preference degree and the landscape of each hole. The results of this study were as follows: As a result of analysis of preference value between groups for each hole, it has been shown that there was scarcely difference with each other. Form the relation between preference degree and spacial structure of hole, the holes making up a superior preference group have been shown that the greater part of the holes had a downward slope or a gentle slope mostly and then a visible ratio of fairway was high, and had diversified scenery by a lotus pond, a solitary planting tree, the roll of a fairway, facilities for convenience, etc. The holes making up a low-ranking preference group have been shown that the greater part of the holes had upward slope or a similar slope to it and had characteries of the bad condition of lawn, the nearby factories and odors, the monotonous scenery of a fairway, an unreasonable mixing of holes, etc. From the relation between preference degree and landscape components forming hole, it has been shown that the preference degree between users and nonusers had positive correlation to the occupied ratio of space of landscape components at Tee and Approach. At Tee, it has been shown that the preference degree of two groups were related with a lawn surface of fairway negatively, a lotus pond, a sky positively, and the preference degree of nonusers was related with iron-top for electric transmission positively. At Approach, it has been shown that the preference degree of two groups were related with iron-top for electric transmission negatively, and the preference degree of nonusers was related with a building positively. From the relation between preference degree group to each hole and the occupied ratio of space of landscape types, it has been shown that the constituent ratio of a high-ranking group was 1:2.4:2.2 and a low-ranking group was 1:4.1:5.1 among vertical type, horizontal type and background at Tee, but the constituent ratio of space of a high-ranking group was similar to a low-ranking group at Approach.

Nowadays, recommender systems suggest lists of items to users considering not only accuracy but also diversity and novelty. However, suggesting the most diverse list of items to all users is not always acceptable, since different users prefer and/or tolerate different degree of diversity. Hence suggesting a personalized list with a diversity degree considering each user preference would improve the efficiency of recommender systems. The main contribution and novelty of this study is to tune the diversity degree of the recommendation list based on the users' variety-seeking feature, which ultimately leads to users' satisfaction. The proposed approach considers the similarity of users' desire diversity as a new parameter in addition to the usual similarity of users in the state-of-the-art collaborative filtering algorithm. Experimental results show that the proposed approach improves the personal diversity criterion comparing to the closest method in the literature, without decreasing accuracy.

Telematics is a kind of the convergence of industries such as an automobile, communication, contents, and so on. Jeju-Do has been selected as a model city for telematics and has carried out the telematics service project. Jeju Telematics contains six service areas including navigation, traffic information, emergency assistance, leisure information, tour destination information, and cultural life information. Jeju telematics project has been planned to be dealt with the aspects of technological skills and content development. In fact, because of the nature of model project for testing information technologies, Jeju telematics has been strongly approached by technical aspects. However, telematics is composed of services for users. Then, the success or fail of telematics project can be dependent upon the demand of users, and, in general, users are influenced by the contents of services. Thus, the contents of services should be also dealt as a major concern in the telematics project. In this sense, the purpose of this study is to examine the degree of recognition and preference of contents by users about telematics service. Examination is proceeded by a survey method. Based on the result of the survey, this paper proposes the alternatives for the future directions of Jeju Telematics project regarding contents.

This study intends to define the concept of human scale and visual preference which is frequently being used by environmental designers, and to explore the dimension of buildings and courtyards which is perceived as "human scale" and "visually preferable" by users (college students). As the subjects of this experiment were college students, "human scale" and "visual preferenoe" that were professional terms must be changed to understandable and compatible concept. The compatible concept for human scale was defined as the degree of friendliness and comfort, and that for visual preference was declined as the degree of like or dislike. The subjects thought that buildings with the height of 2.73 ∼5. 83 storides, the length of 27.44∼44.00m and the height ratio of 1.81 ∼5.41 were in human scale, and that buildings with height 2.60 ∼ 6.00 stories, the length of 25.7∼55.00 and the height ratio of 1.32∼6.41 were visually preferred. The block game used in this study was Proved to he a reliable and valid experimental method.

Purpose of this thesis is to find out the relationship among the amount of change and the visual cognition, and the visual preference which people like and can feel. Through the investigation of relationships between the amount of change, which indicates the degree of visual variation and the visual preference, the amount of change and the visual cognition, and the visual preference and the visual cognition, basic design data will be supplied, which can satisfy users' desire as much as possible in the most economic way. In order to investigate the relationship between the visually produced the amount of change and preferences, graphic simulation, in which variables other than the visual change are controlled, has been proceeded. Graphic factors of the visual change in the cyber exterior space are determined on the point of location (base plane, vertical plane, overhead plane), shape, size and color. As for the relationship between the amount of change and the preference, only the size is effective. since preferences on the location, shape and color are individual preferences, no common trend can be found. Therefore, we cannot say that which shape or color is better, Since the location, shape and color are qualitative change and the size is the quantitative change, the size can be the measurable change quantity. The relationship between the amount of change of size and the degree of preference is found to be inverse U-shape, i.e., as the amount of change of size increases the degree of preference first increases and, after a certain level, decreases. The same result has been obtained in photo simulation.

The study investigated the users' functional requirement, degree of acceptance and preference of game broadcast real-time review .Secondly it comparatively analyzed the types and locations of game broadcast real-time review through eye tracking tech. The results show that users have high functional requirements and high acceptance for game broadcast real-time review but their preference has no significant correlation with the feature. Among the types of game broadcast real-time review the type with translucent text bubble took the highest visual attention. The above shows that the users' visual behavior has the tendency of special style. The visual attention analysis results of different types and locations of game broadcast real-time review in the study can play a guiding role in the interface design of real-time review feature in the future.

The importance of the community centers has been increased throughout the decade. With the interest on the centers, the quality of the architectural design of the centers have been much improved. But the importance of the interior design and color' design of the centers have been ignored. It is quite sure that the quality of the interior design impact on the satisfaction degree of the users. And color is the important element which can control the quality of the interior design economically. This study surveyed the three community centers in Seoul to investigate the status of the color usages. And to consider the user's need, and preference in color design, this study performs the questionnaire about the color image and color pallette preference of the users and interior design professionals. Mainly highly bright and low chromatic YR colors were used, giving rigid and monotonous atmosphere. The most preferred color image were warm, bright and secondly friendly, simple, soft, open. And the preference for pallette were various but we can find the difference of color preference and color combination type according to the user's group. As a result, This study proposes the basic guidelines for color design, such as ideal color Image and color and color combination type and color pallette. This proposals can be applied as a basic guideline for color design of the community centers.
