The purpose of the study was to investigate the body cathexis, ideal body shape, clothing satisfaction and their interrelationships. The subjects were 445 middle- and high- school girls. The findings were as follows : the subjects were more satisfied with their face appearance than body parts. They were very unsatisfied with thigh. leg and weight. Generally they were more satisfied with upper body than lower body, and more satisfied with length measurements than girth measurements. They accepted 169.19cm as ideal height and 49.18kg as ideal weight. The middle-school girls wanted to be taller than high-school girls by 3cm. But the ideal weight of both were almost same. The Rohrer indices indicated that the subjects were normal to slender type. But the Rohrer indices calculated using ideal height and ideal weight showed that the subjects thought extremely slender type as ideal body shape. The attitude of body was evaluated by two factors. the awareness of body shape and the physical attractiveness. The awareness of body shape was deeply influenced by girth measurements and lower body parts. And physical attractiveness was severely affected by face appearance. Weight was more important than height in regard to body cathexis. The ideal body shape was independent of individual situation but was formed by social value. The satisfaction of clothing in terms of design related aspects was influenced by body cathexis. Also the more satisfied with their body. the more they felt comfortable for their clothing. The body cathexis was interrelated with the satisfaction of clothing in some aspects.

This study aims to investigate the thoughts of the utopians for the ideal community in 19th century. Around late 18th century, the ideal community proposals by the utopians were coming out as an alternative to reform the social and economical structure. The experimental community proposals which suggested by the utopian socialists such as Robert Owen and Charles Fourier took their emphasis on the social reform to improve the environment of work in terms of social and economical organization. While the thoughts of ideal community showing up in the literature by utopians were based on the state socialism that accompanied by the ultimate corrective system of production and distribution and the unified social system, the physical organization was described in more detail without a restriction in contrast to the real proposals for the ideal community. Based on the experimental community and the ideal community in the literature in 19th century, the urban model of late 19th century were proposed as a real community model. With the optimistic belief to the technological development resulted from the Industrial Revolution, the urban models of utopia placed greater emphasis on the physical organization than the previous ideal communities in 19th century and had much influence on the modern urban planning in 20th century.

Let R denote a commutative noetherian ring, and let 𝐱 := x1, …, xd be an R-regular sequence. Suppose that 𝖆 denotes a monomial ideal with respect to 𝐱. The first purpose of this article is to show that 𝖆 is irreducible if and only if 𝖆 is a generalized-parametric ideal. Next, it is shown that, for any integer n ≥ 1, (x1, …, xd)n = ⋂P(f), where the intersection (irredundant) is taken over all monomials f = xe11 ⋯ xedd such that deg(f) = n - 1 and P(f) := (xe1+11, ⋯, xed+1d). The second main result of this paper shows that if 𝖖 := (𝐱) is a prime ideal of R which is contained in the Jacobson radical of R and R is 𝖖-adically complete, then 𝖆 is a parameter ideal if and only if 𝖆 is a monomial irreducible ideal and Rad(𝖆) = 𝖖. In addition, if a is generated by monomials m1, …, mr, then Rad(𝖆), the radical of a, is also monomial and Rad(𝖆) = (ω1, …, ωr), where ωi = rad(mi) for all i = 1, …, r.

This study compares by gender the preference about ideal female height and body parts. Data was collected through a survey of 203 males and 236 females. The results are as follows: Males and females prefer 161~165cm as the ideal female height and 176~180cm as the ideal male height. In regards to the ideal height difference between couples, both males and females prefer males to be taller, with the head of the female at the same height as the neck of the male. Males and females prefer the shorter height than the ideal height of a fashion model and Miss Korea who got the prize from the korean beauty contest. In the case of Miss Korea, there has been a demand for tall women to participate in world beauty contests. However, this study shows that young people prefer a shorter height than the society expects. Males and females think the shoulder width is ideal when it is 2 times wider than the width of a face in regards to the preference of the ideal female body parts. There is a difference between males and females in the ideal breast size. Males prefer C-cup size while females prefer B-cup size. The ideal size of waist preferred is between 60~65cm to both males and females. The ideal shape of legs preferred to both males and females is a slightly muscular shape.

Patients who underwent hip arthroplasty using the conventional fat suppression technique (CHESS) and a new technique (IDEAL) were compared quantitatively to assess the effectiveness and usefulness of the IDEAL technique. In 20 patients who underwent hip arthroplasty from March 2009 to December 2010, fat suppression T2 and T1 weighted images were obtained on a 3.0T MR scanner using the CHESS and IDEAL techniques. The level of distortion in the area of interest, the level of the development of susceptibility artifacts, and homogeneous fat suppression were analyzed from the acquired images. Quantitative analysis revealed the IDEAL technique to produce a lower level of image distortion caused by the development of susceptibility artifacts due to metal on the acquired images compared to the CHESS technique. Qualitative analysis of the anterior area revealed the IDEAL technique to generate fewer susceptibility artifacts than the CHESS technique but with homogeneous fat suppression. In the middle area, the IDEAL technique generated fewer susceptibility artifacts than the CHESS technique but with homogeneous fat suppression. In the posterior area, the IDEAL technique generated fewer susceptibility artifacts than the CHESS technique. Fat suppression was not statistically different, and the two techniques achieved homogeneous fat suppression. In conclusion, the IDEAL technique generated fewer susceptibility artifacts caused by metals and less image distortion than the CHESS technique. In addition, homogeneous fat suppression was feasible. In conclusion, the IDEAL technique generates high quality images, and can provide good information for diagnosis.

We give the characterization of an intuitionistic fuzzy ideal[resp. intuitionistic fuzzy left ideal, an intuitionistic fuzzy right ideal and an intuitionistic fuzzy bi-ideal] generated by an intuitionistic fuzzy set in a semigroup without any condition. And we prove that every intuitionistic fuzzy ideal of a semigroup S is the union of a family of intuitionistic fuzzy principle ideals of S. Finally, we investigate the intuitionistic fuzzy ideal generated by an intuitionistic fuzzy set in $S^1$.

We introduce the concept of an interval-valued fuzzy generalized bi-ideal of a semigroup, which is an extension of the concept of an interval-valued fuzzy bi-ideal (and of a noninterval-valued fuzzy bi-ideal and a noninterval-valued fuzzy ideal of a semi-group), and characterize regular semigroups, and both intraregular and left quasiregular semigroup in terms of interval-valued fuzzy generalized bi-ideals.

For a field K, a square-free monomial ideal I of K[$x_1$, . . ., $x_n$] is called an f-ideal, if both its facet complex and Stanley-Reisner complex have the same f-vector. Furthermore, for an f-ideal I, if all monomials in the minimal generating set G(I) have the same degree d, then I is called an $(n, d)^{th}$ f-ideal. In this paper, we prove the existence of $(n, d)^{th}$ f-ideal for $d{\geq}2$ and $n{\geq}d+2$, and we also give some algorithms to construct $(n, d)^{th}$ f-ideals.

A quasi ideal importance sampling simulation method combined in the conditional expectation is proposed for the structural reliability estimation. The quasi ideal importance sampling joint probability density function (p.d.f.) is so composed on the basis of the ideal importance sampling concept as to be proportional to the conditional failure probability multiplied by the p.d.f. of the sampling variables. The respective marginal p.d.f.s of the ideal importance sampling joint p.d.f. are determined numerically by the simulations and partly by the piecewise integrations. The quasi ideal importance sampling simulations combined in the conditional expectation are executed to estimate the failure probabilities of structures with multiple failure surfaces and it is shown that the proposed method gives accurate estimations efficiently.

Let X be a Banach space and Z a closed subspace of a Banach space Y. Denote by Ｌ(X, Y) the space of all bounded linear operators from X to Y and by Ｋ(X, Y) its subspace of compact linear operators. Using Hahn-Banach extension operators corresponding to ideal projections, we prove that if either $X^{**}$ or $Y^{*}$ has the Radon-Nikodym property and Ｋ(X, Y) is an M-ideal (resp. an HB-subspace) in Ｌ(X, Y), then Ｋ(X, Z) is also an M-ideal (resp. HB-subspace) in Ｌ(X, Z). If Ｌ(X, Y) has property SU instead of being an M-ideal in Ｌ(X, Y) in the above, then Ｋ(X, Z) also has property SU in Ｌ(X, Z). If X is a Banach space such that $X^{*}$ has the metric compact approximation property with adjoint operators, then M-ideal (resp. HB-subspace) property of Ｋ(X, Y) in Ｌ(X, Y) is inherited to Ｋ(X, Z) in Ｌ(X, Z).
