Character plays an important role not merely in animation but also in the modern image industry. From this perspective a new academic approach to and an analysis of character seems of much significance. With this in view this study carried out an elucidation of the basic factors and concept of plasticity for the creation of animation character on the basis of animation structural elements. Furthermore, an inquiry was conducted into fundamental requirements and factors of animation characters, human anatomy serving as the basis of forms for animation character modelling, the characteristics and techniques for creating animation cubic character, and then suggested a method of creation. In this process it was revealed that integral cubic character was applied to diverse animations, that character of high density was prerequisite for the creation of creative and effective animations, and that cubic character plasticity played a catalytic role in activation popular sympathy and the character industry.

We focus on the structure of the set of noncentral idempotents whose role is similar to one of central idempotents. We introduce the concept of quasi-Abelian rings which unit-regular rings satisfy. We first observe that the class of quasi-Abelian rings is seated between Abelian and direct finiteness. It is proved that a regular ring is directly finite if and only if it is quasi-Abelian. It is also shown that quasi-Abelian property is not left-right symmetric, but left-right symmetric when a given ring has an involution. Quasi-Abelian property is shown to do not pass to polynomial rings, comparing with Abelian property passing to polynomial rings.

A microsurgery telerobotic system has been developed to aid surgeons from physiological tremor, eye stram, hand tremor, contagious and radioactive hazard. This paper identifies four general areas of advanced microsurgery and analyzes the motion, tools, accuracy and applying forces with respect to microsurgery tasks, and proposes the criteria to design the microsurgical robot. The analysis of microsurgery can be helpful to clarify some basic concept and design of surgical robots. Based on this analysis results, we propose an efficient in-parallel-platform manipulator having a special kinematic structure suitable for microsurgery.

The purpose of this research is to introduce the concept of "relationship formation factors" in inter-firm relations and to empirically demonstrate that they are effective in improving the relationship results by means of anmediating variable. Therefore, the basic model of this study consists of the independent, mediating, and dependent variables. First, the independent variable, that is, the relationship formation factors, is further classified into three components： transactional, relational, environmental characteristics. Then, the study empirically examines how each of the three components influences the dependent variable, that is, the business performance(Load Factor), by way of the mediating variables, that is, trust and relationship commitment.

The distribution line through which electricity is supplied from substation to customer generally varies by underground line and overhead line. In contrast that the underground line is shielded, the overhead lines do not have the shield layer. To overcome this weak point of the overhead lines, the aerial bundled cable(ABC) connection systems have been developed. The basic concept of the ABC connection system is the application of the underground cable system containing complete shield layer to the overhead cable system. The ABC system is the innovative technologies which enable the prevention of electric shocks, reduction of the maintenance charge and damage of the cable. This paper give a full detail of vertical connection system applied within a country.

The purpose of this paper is to introduce the concept of strongly extending modules which are particular subclass of the class of extending modules, and study some basic properties of this new class of modules. A module M is called strongly extending if each submodule of M is essential in a fully invariant direct summand of M. In this paper we examine the behavior of the class of strongly extending modules with respect to the preservation of this property in direct summands and direct sums and give some properties of these modules, for instance, strongly summand intersection property and weakly co-Hopfian property. Also such modules are characterized over commutative Dedekind domains.

According to increasing dependancy of national competitiveness on her level of science and technology, the Korean Government devote herself to expansion of technological capability in nation-wide. As a result, the numbers and sizes of national R&D programs, one of public technology policies, are abruptly increased. Recently, the government closely examines the introduction of performance-based budgeting regime as well as the accountability issue in public sector. In the fulfillment of accountability, it has considerable importance that the government executes measurement and strategic management of their performances of all the national R&D programs, how they are properly executed in conformity with respective missions and characteristics. It needs a tool for clearly measuring the programs' performances. In this study, the Balanced Scorecard (BSC) is suggested as an alternative. However, the logics of ordinary BSC cannot be directly applied to the program unit. This study reviews the basic concept and principles of BSC and discusses the necessary conditions for proper application of BSC into national R&D programs.

The main purpose of this study is to investigate the Korean youths' impressions of the scientist. The concept of impression is assumed to reflect our significant view of an object better than that of image. That is, the basic assumption is that we tend to behave toward an object, based on its impression which is conceived to be "significant". In late August and early September 2002, a national survey for 1,204 youth (406 for 5th grad; 381 for 8th grade; and 417 for 11th grade) was conducted to find the Korean youths' impressions of the scientist. Our major finding is that the Korean youths' most impressions of the scientist were re his or her activities such as inventing, experimenting, researching, etc. And the major sources of those impressions were found to be television, book, and class. Other findings were about youths' impressions of the science teacher and opinions of the scientist as a profession. Finally, some policy-related implications based on survey results were presented at the end.

In this paper, we propose a method of selecting new types of rectangle features that are suitable for facial expression recognition. The basic concept in this paper is similar to Viola's approach, which is used for face detection. Instead of previous Haar-like features we choose rectangle features for facial expression recognition among all possible rectangle types in a 3${\times}$3 matrix form using the AdaBoost algorithm. The facial expression recognition system constituted with the proposed rectangle features is also compared to that with previous rectangle features with regard to its capacity. The simulation and experimental results show that the proposed approach has better performance in facial expression recognition.

This paper shows a method to design complementary filter using least square. The complementary filter is one of useful filters estimating angle. The basic concept of this filter is to enhance advantages of each sensor that angle detecting using a gyroscope has good accuracy at a high frequency and an accelerometer at a low frequency. When designing complementary filter, the most commonly used method is using cut-off frequency. However, it may be not easy to obtain a cut-off frequency. This paper presents a systematic method to determine the coefficients of the complementary filter using well-known linear least squares minimizing error between estimating angle and true angle.
