The level of representation, exploration and artistry by age and sex was examined in twenty children in each of 4-, 5-, and 6-year old groups attending an early education facility in Pundang City, Kyong'gi Province. Evaluation was by the scoring system used in the Project Spetrum(Krechevsky, 1994) with children's drawings of an animal, person, imaginary animal and 3D work with clay. Data were analyzed by 2-way ANOVA and Duncan test. The level of representation was lower than exploration and artistry in the 4-year-old groups. Level of artistry was lower than representation and exploration in the 5-and 6-year-old groups. The older children and girls showed higher scores than the younger children and boys in representation and exploration. There were differences between 4-and 5-year old children in artistry development.

To accomplish various and complex tasks by intelligent robots, improvement is needed not only in mechanical system architecture but also in control system architecture. Hybrid control architecture has been suggested as a mutually complementing architecture of the weak points of a deliberative and a reactive control. This paper addresses a control architecture of robots, and a behavior representation methodology. The suggested control architecture consists of three layers of deliberative, sequencing, and reactive as hybrid control architecture. Multi-layer behavior model is employed to represent desired tasks. 3D simulation will be conducted to verify the applicability of suggested control architecture and behavior representation method.

The clinical assessment for preschool children who are known to have problems in selfreporting tends to be dependent on outsiders' reporting. Thus, the direct assessment of children's inner experience, thoughts and feelings is difficult. MacArthur Story-Stem Battery(MSSB) developed to learn more about preschool children's mental representation in play is used in this study to help assess clinical preschool children through developmental study of normal children's mental representation. Fifty five children(32boys and 23girls) who performed MSSB, IQ Test, Peabody Picture Vocabulary Test-Revised(PPVT) were videotaped and were analyzed. The results of this study were as follows：1) Children frequently displayed negative mental representation such as atypical negative response, reparation/guilt, punishment, personal injury and so on during emotionally laden play situation. 2) Mental representation of parent appeared positive, disciplinary, and negative in respective. 3) As a result of factor analysis of MSSB content themes, aggressive, prosocial, and oppositional content theme composites were generated. Aggressive content included atypical negative response, aggression, personal injury, and exclusion. Prosocial content included affection, affiliation, and reparation/guilt. Oppositional content included punishment and non-compliance. 4) Mental representation of parent and content themes showed significant correlation. Positive, negative, and disciplinary representation were significantly correlated for prosocial(r=0.40), aggressive (r=0.52), and oppositional(r=0.75) content theme respectively. 5) Among the correlations between parental mental representations and emotional responses, positive parental representation and anxiety showed significant negative correlation(r=-0.43). 6) Among the correlations between content themes and emotional responses, there were significant positive correlations between aggressive(r=0.28) and oppositional content themes(r=0.29) and distress, and were significant negative correlations between prosocial content theme and concern(r=-0.29) and anxiety(r=-0.43). According to the above results, preschool children frequently displayed negative mental representation in emotionally conflictual play situation. Children with more prosocial themes in their stories exhibit more positive parental mental representation. Also, children with more aggressive themes tend to display more negative parental representation and negative emotional responses.

The genetic algorithms have been used to take a near optimal solution because The generation of the optimal Steiner tree from a given network is NP-hard problem,. The chromosomes in genetic algorithm are represented with the floating point representation instead of the existing binary string for solving this problem. A spanning tree was obtained from a given network using Prim's algorithm. Then, the new Steiner point was computed using genetic algorithm with the chromosomes in the floating point representation, and it was added to the tree for approaching the result. After repeating these evolving steps, the near optimal Steiner tree was obtained. Using this method, the tree is quickly and exactly approached to the near optimal Steiner tree compared with the existing genetic algorithms using binary string.

This study aims to investigate the usage patterns of users in Social Network Services (SNS) where is an upsurge. Specifically, the paper considers the reason why young people more and more prefer online (or mobile) SNS activities rather than offline face-to-face social relationship. Furthermore, the drivers which affect SNS usages are considered from users' personal characteristics and social influences. User's personal characteristics include their personalities (extraversion and introversion), narcissism, and life satisfaction. Social influences involve subjective norm, visibility, and image. Affected by personal and social factors in SNS, users intend to show positive self-presentation, which refers to a behavior to selectively expose his/her goodness to others. As one of the most influential drivers affecting SNS usage, the positive self-representation has an effect on the level of SNS usage. Thus, this paper suggests the hypothesized research model focusing on positive self-representation in the relationship among personal characteristics, social influence, and user's behavior in SNS. Empirical data analysis with 100 questionnaires suggests that all hypotheses were adopted except for the effect of visibility among social influence factors on positive self-representation.

This study discovers the dynamic nature of an interactional hierarchy as well as an institutional hierarchy in the use of Korean honorifics. Data was collected from the conversations of two Korean female interlocutors. The interlocutors met for the first time in the U.S. and often changed their use of honorifics. The paper examines the method in which the two interlocutors negotiate hierarchies during interaction and how the negotiation is reflected in their use of honorific shifts. The paper also investigates honorific shifts in terms of self-representation to suggest that there is another hierarchy at work other than the institutional hierarchy. An examination of the data shows that the shifts occurred not randomly but strategically. The findings suggest that 1) interlocutors may negotiate interactional hierarchy during their conversation, often in the same sentence, 2) interactional hierarchy often cross the boundary of the institutional hierarchy to obtain interactional goals, in this case, intimacy, and 3) the utterance contents may play a significant role in the interlocutors' honorific shifts.

This paper proposes a dynamic approach to anaphoric resolution in conjunction phrases, in terms of Discourse Representation Theory. Unlike Kamp, van Genabith, and Reyle (forthcomming)'s analysis, it proposes two different types of discourse representation structures for conjunction phrases; one for coordinate phrases such as and conjunction phrases and the other one for subordination conjunction phrases such as when subordination phrases. Following Chung (1992), Chung (2004), every element is processed in the order of occurrence and conjunction operators in a non-sentence-initial position cause the ongoing DR to split in two with the same index. DRS conditions and accessibility are accordingly modified so that DRs for conjunction clauses can be accessible from DRs for main clauses.

The purpose of the study is to analyze children's proportional reasoning and problem solving in proportional problems with/without iconic representations. Proportional problems include 3 tasks such as (a) without any picture, (b) with simple picture, and (c) with/without iconic representation. As a result, children didn't show any significant differences in two tasks such as (a) and (b). However, children showed better proportional reasoning with iconic representation. In addition, 'build-up expression' strategy was used mostly in solving problems and 'additive strategy' was shown as an error which students didn't make an appropriate proportional relation expression and they made a wrong additive strategy.

Most current 3D digital maps are 2.5 dimension models based on DEM, which can only be recognized, browsed and operated by a special software, far from meeting the needs of a modern digital city (global) with the distributed, isomerous and multiple application on the real 3D representation and open sharing models. In this paper, a new generation digital city oriented 3D digital map is studied. Firstly, a real 3D digital map representation is presented. And then, some key techniques and methods for browser-based 3D digital map’s representation, display and operation are introduced, which can realized the open sharing of 3D map in distributed, isomerous and multiple application environment. Furthermore, the scale driving technique of proposed 3D digital map is also studied. And currently, some developments based on some of the above methods are being carried to provide key and general platform for other application software’s development.

Since the 1960's, diverse movements that oppose the uniform design tendency of modernism appears in Italy. Especially, Gaetano Pesce, who opposed uniformity and standardization that are based on mass production system, had interests in making unique product, not an identical product, while accepting modern production technology. Therefore, the purpose of this study is to comprehend Pesce's design, which creates diversity by arranging contingent, non-predictive, and episodic aspects in creative and acceptance processes according to the intension of the designer within mass production system, as a non-representational characteristic, which appears widely in modern thought and the arts, and examine how it is materialized in detailed design work. The study methods are first examining non-representation with theoretical contemplation and dealing with the design philosophy of Pesce based on the examination. Next, in order to discover non-representational characteristics that appear in the work of Pesce, it examines from introducing worker's creativity, user's possibility of choice, openness in the working process, and the aspects of researching materials. And a specific application method will be drawn through case analysis centered on furniture design. Gaetano Pesce's design that denies the world of representation based on the sameness comes to possess non-representational characteristics that acknowledge contingency and ceaselessly create difference by intentionally arranging during the working process.
