Most research on high-rise housing has focused on low-income residences, and usually the psychological and social well-being of women and children. The validity of such findings are questionable for other populations since high-rise living has served other groups and their various needs in particular settings. Lack of knowledge and understanding about high-rises has represented an obstacle to the accurate representation of American urban reality in residential environments. The review of literature and factor analysis identified Important environmental factors. The survey was conducted in the selected downtown high-rise communities of major U.S. cities. Analyses revealed that there were unique characteristics of residents who prefer to live in this type of housing. It was also found that living in middle-income urban high-rise condominiums does not contribute significantly to the problems associated with high-rise living itself. Even though there were some deficiencies of social interaction and activities among residents, the middle-income condominiums were serving particular residents as maintenance-free and safe place imprinted by a positive image of sweet memories or sometimes by a window view presiding over downtown skyline.

Let G be a compact semialgebraic group and M a semi-algebraic G-set. We prove that there exists a semialgebraic slice at every point of M. Moreover M can be covered by finitely many semialgebraic G-tubes. As an application we give a different proof that every semialgebraic G-set admits a semi algebraic G-embedding into some semialgebraic orthogonal representation space of G, which has been proved in [15].

In this paper we characterize multi-Jensen functions f : $V^n\;{\rightarrow}\;W$, where n is a positive integer, V, W are commutative groups and V is uniquely divisible by 2. Moreover, under the assumption that f : $\mathbb{R}\;{\rightarrow}\;\mathbb{R}$ is Borel measurable, we obtain representation of f (respectively, f, g, h : $\mathbb{R}\;{\rightarrow}\;\mathbb{R}$) such that the Jensen difference $$2f\;\(\frac{x\;+\;y}{2}\)\;-\;f(x)\;-\;f(y)$$ (respectively, the Pexider difference $$2f\;\(\frac{x\;+\;y}{2}\)\;-\;g(x)\;-\;h(y))$$ takes values in a countable subgroup of $\mathbb{R}$.

A knot complement admits a pseudo-hyperbolic structure by solving Thurston's gluing equations for an octahedral decomposition. It is known that a solution to these equations can be described in terms of region variables, also called w-variables. In this paper, we consider the case when pinched octahedra appear as a boundary parabolic solution in this decomposition. The w-solution with pinched octahedra induces a solution for a new knot obtained by changing the crossing or inserting a tangle at the pinched place. We discuss this phenomenon with corresponding holonomy representations and give some examples including ones obtained from connected sum.

Subjects were 66 3- to 4-year-old-Children of unemployed mothers from upper middle class families. Attachment behaviors were measured with the Preschool Strange Situation(Cassidy and Marvin, 1992) and classified as secure, avoidant, dependent, or disorganized. Narrative representations of mothers by Children were obtained by video taped interviews using the MacArthur Story-Stem Battery and coded by the MacArthur Narrative Working Group(1997) system. Data were analyzed with descriptive statistics and t test. Results were that children in the secure group showed more positive representations of their mothers, more prosocial story themes, had higher scores in theme coherence and showed more positive emotional expression than those in the insecure group. The attachment behaviors of the 4 groups(A, B, C, D) were closely correlated with the attachment representations shown in MSSB.

In this paper, we propose a channel router for non-rectangular channels with variable channel height and via minimization method. Non-rectangular routing areas are splitted into 3 parts, upper, lower and rectangular channel. The upper and lower parts are routed by a modified "left edge algorithm." The rectangular channel is routed by channel routing method using the channel representation graph. After routing, redundant vias are eliminated by the rules composed of 3 groups.

As an influential political leader, Queen Elizabeth II holds the link between past queens and today's women political leaders and her dress represents so much in accordance to her role. It is important to analyze the dress and role enactment of Queen Elizabeth II in order to provide a guide to the future women political leaders all over the world. The Queen's dress helps her show tradition which has developed over one thousand years of history. She represents Britain to the world focusing on national identity and unity. The Queen always distinct herself from the rest of the world to show the pride of British Monarch, but when she is visiting other counties for diplomatic relationships she would surely show a friendly gesture on her dress to assimilate herself with that country. Also, same as all other women, the Queen seeks practicality in her dress. Therefore, I was able to classify the Queen's dress into jive groups as a way of role enactment. They are tradition, representation, distinction, assimilation, and practicality.

The purpose of this paper is to find expressions of the Fricke spaces of some basic surfaces which are a three-holed sphere ${\sum}$(0, 3), a one-holed torus ${\sum}$(1, 1), and a four-holed sphere ${\sum}$(0, 4). For this goal, we define the involutions corresponding to oriented axes of loxodromic elements and an inner product <,> which gives the information about locations of axes of loxodromic elements. The signs of traces of holonomy elements, which are calculated by lifting a representation from PSL(2, $\mathbb{C}$) to SL(2, $\mathbb{C}$), play a very important role in determining the discreteness of holonomy groups.

We have developed a real-time software tool to extract a speech feature vector whose time sequences consist of three groups of vector components; the phonetic/acoustic features such as formant frequencies, the phonemic features as outputs on neural networks, and some distances of Japanese phonemes. In those features, since the phoneme distances for Japanese five vowels are applicable to express vowel articulation, we have designed a switch, a volume control and a color representation which are operated by pronouncing vowel sounds. As examples of those vowel interface, we have developed some speech training tools to display a image character or a rolling color ball and to control a cursor's movement for aurally- or vocally-handicapped children. In this paper, we introduce the functions and the principle of those systems.

This paper introduces a new scheme for neural network classifier which can describe the shape of patterns in clustered group by using a self-organizing teeming algorithm. The prototype based neural network classifier can not describe the shape of group and it has low classification performance when the data groups are complex. To improve above-mentioned problem, new neural scheme is introduced. This proposed neural network algorithm can be regarded as the extension of self-organizing feature map which can describe The experimental results shows that the proposed algorithm can describe the shape of pattern successfully.
