In this paper, methods of human figure representation in computer graphics are described. Many applications of the human figure representation are found in areas including industry, advertisement, and cartoon production and further research for the methods that show the human figure more realistically is ex- pected. Two analytic methods for human model, kinematics and dynamics, are ex- plained and the characteristics of the man-machine interface systems that include human figure representation are presented. Various techniques of the human figure representation based on kinematics or(and) dynamics are discussed and representation methods of human body segments such as hand, face, spine are introduced in this paper.

The purpose of this study is to pursue the way of human body expression for prospecting of future fashion illustration through research of the methods and meaning expressed in the works of 30 years by Antonio Lopez. The research was conducted by looking into the perception of the body between 1960s and 1980s, when Lopez worked actively, on the basis of the discourse, art and fashion for the femininity and studying the representation method and meaning of the body in his works. Lopez suggested an index of the ideal beauty of the times through the representation of the immature body like a child in the 60s, the glamorous body in the 70s and the exaggerated muscular body in the 80s by predicting the changes of the perception of femininity and ideal beauty. As the result of this research, it is found that Lopez employed the art form for the representation of the body in his works and presented the polysemous implications of the art form in the context of the body expression. In addition, he redefined sexuality by focusing on the code that confronted the conventional women's morals by changing the representation method of the women's pose, and depicted the other's image such as the colored races, departing from the ideal human body based on the white women. Lastly, he deconstructed the human body in various ways, thereby enlarging the concept of the human body in the existing fashion illustration.

This paper is concerned with knowledge representation schemes best suited for human resource management (HRM) problem domains including human resource planing, selection, placement, compensations, performance evaluation, training and labor-management relations. In order to suggest the scheme we consider two research gods. First, we evaluate and prioritize. The knowledge representation techniques of frames rules, semantic nets and predicate logic that hove been recommended to managerial domains. The combined Analytic Hierarchy Process technique is employed to combine individual judgments effectively between two different expert groups. As a result if we are to select a single knowledge representation technique, a frame representation is best for most HRM domains and to combine frames with others is another choice. Second as a strategy for knowledge representation schemes we show some examples for each damn in terms of labeled semantic nets and two types of rules derived from the semantic nets. We propose nine knowledge components as ontologies. The labeled semantic nets con provide some benefits compared with conventional one. More clearly definea node rode information maces it easy to find the ac information. In the rule sets, the variables are the node of the semantic nets. The consistency of rules is validated by the relationship of the knowledge components.

During the communication and interaction with a human using motions or gestures, a humanoid robot needs not only to look like a human but also to behave like a human to make sure the meanings of the motions or gestures. Among various human-like behaviors, arm motions of the humanoid robot are essential for the communication with people through motions. In this work, a mathematical representation for characterizing human arm motions is first proposed. The human arm motions are characterized by the elbow elevation angle which is determined using the position and orientation of human hands. That representation is mathematically obtained using an approximation tool, Response Surface Method (RSM). Then a method to generate human-like arm motions in real time using the proposed representation is presented. The proposed method was evaluated to generate human-like arm motions when the humanoid robot was asked to move its arms from a point to another point including the rotation of its hand. The example motion was performed using the KIST humanoid robot, MAHRU.

The purpose of this study is to investigate the formation of parental beliefs. For this study, 154 unmarried university students were asked to fill in a packet of survey questionnaire about parental beliefs, the internal representation of childhood, and communication with their parents. Data collected were analyzed using correlation and multiple regression by SPSS PC program. It was reported that the internal representation of parenting formed in childhood influences the development of rational authoritative beliefs, distancing beliefs, and direct authoritative beliefs. Also, the open communication with parents affected the distancing beliefs and rational authoritative beliefs.

Chair is one of objects which are closely connected with human body and is a symbol which represents human essence and culture. Symbolism embodies the meaning of expression through transfering the immaterial structure to tangible form. Therefore chair embodies the essential internal desires of human by means of its symbolic representation. In order to understand the essential human desires included in the symbolism of chair it is necessary to consider these desires with respect to cultural and historical context. in this study four essential internal desires of human are investigated through the symbolic representation of chair that is the desires on human psychological comfort authority freedom and eroticism. The purpose of this study is to emphasize the necessity of the design approach based on the understanding of essential internal desires of human which is pursued from the object by user.

Skeleton transform of which the medial axis transform is the most popular has been proposed as a useful shape abstraction tool for the representation and modeling of human posture. This paper explains this proposition with a description of the areas in which skeletons could serve to enable the representation of shapes. We present algorithms for two-dimensional posture modeling using the developed simplified shock graph (SSG). The efficacy of SSG extracted feature vectors as shape descriptors are also evaluated using three different classifiers, namely, decision tree, multilayer perceptron, and support vector machine. The paper concludes with a discussion of the issues involved in using shock graphs to model and classify human postures.

Human activities recognition is a challenging task due to its complexity of human movements and the variety performed by different subjects for the same action. This paper presents a recognition algorithm by using skeleton information generated from depth maps. Concatenating motion features and temporal constraint feature produces feature vector. Reducing dictionary scale proposes an improved fast classifier based on sparse representation. The developed method is shown to be effective by recognizing different activities on the UTD-MHAD dataset. Comparison results indicate superior performance of our method over some existing methods.

With the rapid development of e-commerce, many customers can now express their opinion on various kinds of product at discussion groups, merchant sites, social networks, etc. Discerning a consensus opinion about a product sold online is difficult due to more and more reviews become available on the internet. Opinion Mining, also known as Sentiment analysis, is the task of automatically detecting and understanding the sentimental expressions about a product from customer textual reviews. Recently, researchers have proposed various approaches for evaluation in sentiment mining by applying several techniques for document, sentence and aspect level. Aspect-based sentiment analysis is getting widely interesting of researchers; however, more complex algorithms are needed to address this issue precisely with larger corpora. This paper introduces an approach of knowledge representation for the task of analyzing product aspect rating. We focus on how to form the nature of sentiment representation from textual opinion by utilizing the representation learning methods which include word embedding and compositional vector models. Our experiment is performed on a dataset of reviews from electronic domain and the obtained result show that the proposed system achieved outstanding methods in previous studies.

This paper proposes a new concept in video called Graphical Video. Graphical Video is a content-based and scalable video representation. A video consists of several elements such as moving images, still images, graphics, characters and charts. All of these elements can be represented graphically except moving images. It is desirable to transform these moving images graphical elements so that they can be treated in the same way as other graphical elements. To achieve this, we propose a new graphical representation of moving images using spatio-temporal clusters, which consist of texture and contours. The texture is described by three-dimensional fractal coefficients, while the contours are described by polygons. We propose a method that gives domain pool location and size as a means to describe cluster texture within or near a region of clusters. Results of an experiment on texture quality confirm that the method provides sufficiently high SNR as compared to that in the original three-dimensional fractal approximation.
