Smart space is a technology that supports humans by interacting with the surrounding environment. Smart space has a built-in dynamic intelligent environment. This paper proposes a framework that provides user-customized dynamic intelligent environments in smart spaces. In the existing research that provides user-customized intelligent services, users' interests are only explicitly analyzed, and smart spaces are not considered. Implicit interest analysis can suggest a service that may be of interest to users rather than explicit interest analysis, but it requires higher performance than explicit interest analysis. Smart spaces can obtain useful information by interacting with information in the space. The framework proposed in the study uses a proximity-based social network of things to fit into a smart space. In addition, the implicit interest analysis provides intelligent information for smart spaces using the social media information and spatial information objects. In addition, we propose a method to prevent performance degradation while maintaining accuracy in consideration of the characteristics of the smart space.

Accurate proofreading Interface requires resolving the ambiguity that occurs when the system determines the relations between the free-form by the user and editing scopes of the document. Proofreading for structure documents such as XML/XHTML involves modification of document structures and modified document also should follow the pre-defined DTD. This paper present a CPI (Context-based Proofreading Interface) based on the XML. The CPI supports free-form drawing of correction marks and provides context-based scope recognition and revision methods. CPI provides both implicit and explicit modification methods for document structures. As a result, the correction mark information produced in this paper includes more accurate scope information than that in other systems.

To produce accurate editing results, the ambiguity of editing scopes related to marked correction signs should be solved. Proofreading the web document modifies the document structures, and the modified structures should be robustly valid for the defined DTD. This paper presents a pen-based proof-reading interface in the XML document. In the proposed interface, correction signs are free-drawn, and the editing scopes are recognized and revised based on the contexts of the document to minimize the ambiguity of the editing scopes. The proposed interface provides both implicit and explicit modification methods for document structures. As a result, the editing scopes processed in the proposed interface are more accurate, and the document structures are maintained valid for DTD after the editing.

The purpose of this research is to examine the impacts of persuasion knowledge and pre-attitude on responses to a persuasive entertainment education program. Persuasion knowledge model was adopted as the theoretical frame and information about the sensational identity of entertainment program was used to activate audience's persuasion knowledge(i.e. resistance). Pre-attitude was measured by the degree of concern about the persuasion topic. The experiment was designed by persuasion knowledge(2) ${\times}$ pre-attitude(2) and participants were randomly assigned in one of the conditions and rated their attitude for the persuasion topic. The implicit measure for attitude was included in addition to the explicit measures in order to reveal unconscious attitudinal changes. The results showed that the allegedly effective entertainment-education can confront the resistance of the audience in some contexts. A significant interaction of knowledge ${\times}$ pre-attitude was found in the result of the implicit attitude. The individuals with high concern about the persuasion topic, compared to those with low concern, were more influenced by the entertainment program and also persuasion knowledge. The interaction was not significant on the explicit attitude, which may present the usefulness of the implicit measure in entertainment-education research.

In a modern society, people are concerned seriously about their travel destinations depending on time, economic problem. In this paper, we propose an non-hierarchical clustering based hybrid recommendation using context knowledge. The proposed method is personalized way of recommended knowledge about preferred travel places according to the user's location, place, and weather. Based on 14 attributes from the data collected through the survey, users with similar characteristics are grouped using a non-hierarchical clustering based hybrid recommendation. This makes more accurate recommendation by weighting implicit and explicit data. The users can be recommended a preferred travel destination without spending unnecessary time. The performance evaluation uses accuracy, recall, F-measure. The evaluation result was shown 0.636 accuracy, 0.723 recall, and 0.676 F-measure.

This paper describes the volumetric data modeling and analysis methods that employ volumetric NURBS or VNURBS that represents heterogeneous objects or fields in multidimensional space. For volumetric data modeling, we formulate the construction algorithms involving the scattered data approximation and the curvilinear grid data interpolation. And then the computational algorithms are presented for the geometric and mathematical analysis of the volume data set with the VNURBS model. Finally, we apply the modeling and analysis methods to various field applications including grid generation, flow visualization, implicit surface modeling, and image morphing. Those application examples verify the usefulness and extensibility of our VNUBRS representation in the context of volume modeling and analysis.

The emergence of the new audiences floating across multimedia platforms and engaging in TV production and distribution have forced producers and broadcasters to think of not only the fragmented distribution of their content but also the development of a new format beyond the frame of traditional TV production. A Korean entertainment TV show My Little Television combining the form of live webcasting and traditional TV show reflects such a trend. Because of the distinct format, My Little Television carries out a unique strategy in managing the two screens - Internet and TV. The dualistic production requires all players to understand not only online subculture and communication styles and methods, but also implicit and explicit rules of traditional TV production. Through text and visual image analysis on the show, this study discusses how MLT negotiates with the original Internet text, the producers' paratext, and the supertext of the national TV network in the context of the transitory screen culture.

The main purpose of this study, based on implicit personality theory and attribution theory, was to examine whether there exist the physical attractiveness stereotype, "what is beautiful is good," in the present Korea, and if exist, what is the content of it. The index of the physical attractiveness of this study was the facial attractiveness judged by 30 female university students. The appropriateness of clothing was manipulated by 4 types of clothing perceived appropriate for two assumed situations by female university students. Three female faces having high, medium, and low attractiveness were simulated with the same body dressed four types of clothing using CAD system, and a total of 12 stimulus persons were created. A total of 524 male and female(262 of male, 262 of female) university students from 3 universities in Kwangju, Korea were participated as subjects in this study. The design for the experiment was a 3$\times$4$\times$2 randomaized factorial, with three levels of facial attractiveness (high, medium, low), and four types attire(formal-masculine, formal-feminine, casual-masculine, casual-feminine), two kinds of context (job interview, dating) in which perceptions were occurred. The data were analysed using factor analysis, MANOVA, t-test and Duncan test. The results were as follows: 1. The facial attractiveness exerted significant positive effects on the evaluation of sociability, adjustment, and potency of her in both of two assumed situations (p<.001, respectively). 2. The appropriateness of stimulus person′s clothing had significant positive erect on the evaluation of sociability of stimulus person in dating context(p<.001). 3. The gender of subjects did not influenced the trait evaluations in both of two assumed situations.

The use of fiber reinforced polymer (FRP) composites in strengthening reinforced concrete beam-column subassemblies has been scrutinised both experimentally and numerically in recent years. While a multitude of numerical models are available, and many match the experimental results reasonably well, there are not many studies that have looked at the efficiency of different finite elements in a comparative way in order to clearly identify the best practice when it comes to modelling FRP for strengthening. The present study aims at investigating this within the context of FRP retrofitted reinforced concrete beam-column subassemblies. Two programs are used side by side; ANSYS and VecTor2. Results of the finite element modeling using these two programs are compared with a recent experimental study. Different failure and yield criteria along with different element types are implemented and a useful technique, which can reduce the number of elements considerably, is successfully employed for modeling planar structures subjected to in-plane loading in ANSYS. Comparison of the results shows that there is good agreement between ANSYS and VecTor2 results in monotonic loading. However, unlike VecTor2 program, implicit version of ANSYS program is not able to properly model the cyclic behavior of the modeled subassemblies. The paper will be useful to those who wish to study FRP strengthening applications numerically as it provides an insight into the choice of the elements and the methods of modeling to achieve desired accuracy and numerical stability, a matter not so clearly explored in the past in any of the published literature.

Storytelling approach is the way to formulate and solve problems using stories. Story is a means to understand and react everyday life that can be regarded as multi-dimensional problems. The approach becomes popular in various fields in conjunction with digital technology. In particular, it is used to solve problems in relation to whole context. In design, storytelling approach is used to clarify design constraints. It can be used to clarify and communicate thoughts for design artifacts, and to understand how the artifacts might be used in particular circumstances. In particular, the approach is useful to use under uncertain circumstances. In architecture, storytelling approach can be used in the area of design generation, design critique and capturing design knowledge. In design generation, it can be used to describe and formulate design experiences rather than simple designing artifacts. The approach formalizes design based on stories of user experiences. Digital technology such as virtual reality can be used to experience designed spaces for design modifications. In design critique area, it can be used to fill uncertain facts for historical buildings as welt as different from present status. Such stories can be used to build digital modeling and used to open criticism. Stories can be used to formalize knowledge in architectural domain as a form of implicit knowledge for certain projects. In architecture, it often is required to design types of environment never experienced before as well as to accomodate fast changing technologies. Storytelling methodology can be used as a method to cope with uncertainty and complexity in design requirements along with accumulating design knowledge.
