This study conducted an evaluation of the streetscape improvement project of the Gwangbok Street through analysis of visual and perceptual characteristics by comparing selected pictures of streetscape before and after the project. This work has conducted an analysis of the environmental factors which influence subjects' satisfaction degrees including physical street equipments and street view factors which are main contents of this project. Using a satisfaction analysis and factor analysis, each factor's significance was verified quantitatively. As a result of the analysis, physical components of the streetscape were classified into 4 types according to project's effectiveness and improvement priorities. These 4 types include (1) Components for maintenance because of higher satisfaction and higher importance, (2) Components for improvement because of lower satisfaction and higher importance, (3) Components for good business fruits because of higher satisfaction and lower importance, and (4) Components for unnecessity because of lower satisfaction and lower importance.

The concept of style provides a useful structure in history of Art. In aspect of formative art, dress and art work are alike, so style is a useful concept in the historical methodology on dress. The main purpose of this study was to apply the art criticism to the historical methodology on dress. For this purpose, documentary studies about style as a tool of historical research were proceeded. The results were as follows : 1. The concept of style consists of the external form and the internal meaning as double roots. Therefore, it's indispensable that the two asp-ects of style, form and meaning, must to be harmonized to describe the historical phenomena in dress. 2. The change pattern of style in dress is not always predeterminate and regular according to the cyclical theory. From the alternative point of view, the change pattern of style could be to describe the continuous theory proposed by kroeber, Brodsky. The whole change of style is considered "liked solution" by this theory.is theory.

Although improper integrals constitute a concept of great utility for Mathematics students, it appears that students are unable to assimilate this concept within the wider system of concepts they learn in their first year of Mathematics studies. In this paper we describe a competence model used in a study about the kind of understanding students possess about improper integral calculus when two registers of representation come into play. Competence will be considered as the coherent articulation of different semiotic registers. After analysing the results of a questionnaire, six students were selected to be interviewed on the basis of their overall results and the significance of their answers. For the interview, five original questions from the questionnaire were used together with a new question. In this article we will analyse, from our theoretical point of view, the work carried out by one student who was interviewed to show how our competence model works and we will discuss this formal competence model used.

As architects and interior designers work farther and farther afield, so the connection of buildings to the particular place they are constructed becomes increasingly. Also, during the past twenty years they have made a habit of asking probing and often uncomfortable questions about how architectural conventions force patterns of behavior. In place of bricks and mortar, they have mixed store, office, clinic, and residence. In this project, the buildings consist of pharmacy, store, dental clinic, oriental clinic and residence. This building was designed by architect to have panoramic views. The view of surrounding road from every wall becomes a constant point of reference, a back drop against which the whole house revolves. Now, all the words can be suitable for describing the oriental clinics. But the oriental clinics of these days may construct the unintentional common image, may be because of the clients sense about the finishing materials or colors in vogue. The Importance of identity in the design of oriental clinic becomes higher increasingly, and with the same reason, the conviction of interior designer.

This work derives a generalized time fractional differential equation governing wave propagation in a radially vibrating non-classical cylindrical medium. The cylinder is made of a transversely isotropic hyperelastic John's material which obeys frequency-dependent power law attenuation. Employing the definition of the conformable fractional derivative, the solution of the obtained generalized time fractional wave equation is expressed in terms of product of Bessel functions in spatial and temporal variables; and the resulting wave is characterized by the presence of peakons, the appearance of which fade in density as the order of fractional derivative approaches 2. It is obtained that the transversely isotropic structure of the material of the cylinder increases the wave speed and introduces an additional term in the wave equation. Further, it is observed that the law relating the non-zero components of the Cauchy stress tensor in the cylinder under consideration generalizes the hypothesis of plane strain in classical elasticity theory. This study reinforces the view that fractional derivative is suitable for modeling anomalous wave propagation in media.

Jeong Si-Han(1625-1707), one of the main representatives of Toegye School in The mid-Korea Dynasty, seeking to live in seclusion of his life engaged in research work, respected by scholars for generations. He, Together with Yi Hyeon Il(1627-1704), carried out a systematic study of Toekye's Interpretation of the "Four Buddings" and "Seven Feelings". In this paper, from a comparative point of view, The author studied Jung Sihan's Li-Qi Theory, Four-Seven Theory, Human Mind and Mind of the Dao. Although his theory of interpretation about Li-Qi Theory, Four-Seven Theory, is the tendency of compromise Toegye and Yulgok's thought, but from the master and servant and upper and lower relationship between Li-Qi and Four-Seven Theory, Jung Sihan preferred the thought of Toegye. The characteristics of Human Mind and Mind of the Dao is Emphasis on Zhu Xi's theory about human mind of "is-to-be"

This study explored contemporary furniture theory and practice in Postmodernism mentioned as one of a kind furniture based on ideas from the tradition since Modernism. Qualitative conceptual analysis as the principal methodology was used to explore the postmodern furniture adopting or reflecting ornament from the tradition presented as postmodern furniture designers' point of view differently and variously. Thus, the examples about one of a kind or one-off furniture were dealt with Postmodern ideas appeared in the doubt over Modernism, Post-Modern furniture ideas from the traditional and Modern architecture, ornamental ism, Postmodern theorists, Postmodern furniture and the criteria. As a result, although one of a kind furniture design appealed newly from and based on the ornament of the tradition has been identified as new design like one of a kind furniture which shows lack of function, the piece with the meaningful ornament makes people happier in their daily life. Hence, one of a kind furniture, a work of art, has been required as striking a balance both function or comfort and aesthetics or beauty which makes the people more enjoyable.

Louis I. Kahn is cleary one of 20th century great architects. The character of his philosophy of architecture can be condensed as simple words; Architectural Essence, because the very nature of his work based on historicity is so fundamental. Some contemporary architects and architectural critics regard it as a symbol of Post-Modern Architecture era expressing relative multiplicity or an expression of Heideggerian existentialism, but others do as the attribute of fundamentalist like absolute Plato's Idea. Comparing the former, studies of the latter theme have been executed superficially and somewhat biasedly for last decades. In the context, this paper attempt to reanalyze Kahn's idea of 'Architectural Essence' with the deep view of Platonist focused on the concept of binary opposition and causality.

Living arrangement is considered an important variable in discussing loneliness and the psychological state of the elderly. From this point of view, this study aimed at Identifying the effects of living arrangements, sociodemographic variables, social activities, and social psychological variables on the psychological loneliness of the rural elderly. Though hierarchical regression analyses. the predictors of loneliness among the rural elderly were identified as single/co-residence living arrangement(r=.49), sense of well-being based on respects for others' perspectives (r: -.22), needs for remarriage (r=.22), and work hours during off- farming season (r: -.19). The effects of living arrangement remained strong and were not influenced by the addition of sociodemographic variables, social activity variable, and social psychological variables. The feeling of loneliness of the elderly who were living alone was higher than among the elderly who were living with someone else. This finding suggests that the loneliness of the rural elderly derives primarily from the lack of family Interaction. Therefore, it is recommended that social welfare policies for the rural elderly be designed to improve their family and social interactions.

This study is to develop a program, with which the motion of the system can be simulated in view of kinematics and dynamics, and then evaluate functional capabilities of many robots in order to select the most suitable one for any given working conditions. According to the theory of Denavit & Hartenberg, rectangular coordinate is set at each joint in the robot of six joints, as this one is the major concern, and transformation matrices are derived between any two coordinates. The necessary displacement of each joint for executing a given a work is obtained from the position and posture transformation and the in-stantaneous velocity of the joint is got from given velocity distribution of the path. The necessary torque of each joint is finally calculated by Newton-Euler Method. This simulation program is applied to a robot with six rotational joints, Rotational angle and torque to time which has a given motion trajectory are figured and also torque to r.p.m.
