Ruthenium(III) unsymmetrical Schiff base complexes, $[Ru(CHBPH-TP)Cl_2]$ and $K[Ru(CHBPH-HB)Cl_2]$ were synthesized, where CHBPH-TP and CHBPH-HB are 5-chloro-2-hydroxybenzophenonethiophencarba aldehydephenylenediimine and 5-chloro-2-hydroxybenzophenonehydroxybenzophe nonephenylenediimine. These Schiff bases were obtained from the reactions of 5-chloro-2-hydroxybenzophenone (CHB) and 2-thiophenecarbaldehyde (TP) or hyroxybenzophenone (HB) and 1,2-diaminobenzene. Elemental analysis, conductivity and infrared studies of the complexes suggest an octahedral geometry around ruthenium. Magnetic moments of the complexes indicate a single unpaired electron in alow spin $d^5$ configuration. The complexes are capable of catalyzing the oxidation of styrene with sodium hypochlorite in the presence of phase transfer agent. Oxidative cleavage of C=C bond is the major reaction pathway to form benzaldehyde for styrene oxidation.

The purpose of this study was to examine how deconstruction, which currently had a great deal of influence on fashion, was actually accepted in view of fashion form or material. In order to track the tendency of deconstructional fashion, an attempt to find out what deconstructional methods were used in fashion design for each formative element was made by looking into earlier studies. Then an analysis was made over the recent fashion magazines. As a result of analyzing four fashion magazines, the most distinctive feature was found to be the use of seethrough cloth. In addition, unsymmetrical form also was immensely used. The next most frequently appeared form was layering, followed by slash or making a hole, lingerie look, padded cloth, indeterminate form, wrinkled cloth and patchworked cloth in the order named. The dominant layering style, the most widely used deconstructional fashion, was that inner cloth could be seen through outer seethrough cloth. The most frequently employed deconstructional cloth was seethrough cloth. Rather than complete seethrough cloth, the shape of lace, net or pattern was employed largely, in which the body could be partially hidden. The most largely used deconstructional method was a slash or making a hole. Most slashes appeared on the front part of the body, to which seethrough stuff was attached in many cases. Based on the above mentional finding. 10 kinds of deconstructional design were proposed for each method.

In this article, static deflection and buckling of functionally graded (FG) nanoscale beams made of porous material are carried out based on the nonlocal Timoshenko beam model which captures the small scale influences. The exact position of neutral axis is fixed, to eliminate the stretching and bending coupling due to the unsymmetrical material change along the FG nanobeams thickness. The material properties of FG beam are graded through the thickness on the basis of the power-law form, which is modified to approximate the material properties with two models of porosity phases. By employing Hamilton's principle, the nonlocal governing equations of FG nanobeams are obtained and solved analytically for simply-supported boundary conditions via the Navier-type procedure. Numerical results for deflection and buckling of FG nanoscale beams are presented and validated with those existing in the literature. The influences of small scale parameter, power law index, porosity distribution and slenderness ratio on the static and stability responses of the FG nanobeams are all explored.

Two epistylid peritrichous ciliates collected from the littoral aquatic plants at pond in a suburb of Ulsan, Korea were identified as Epistylis plicatilis Ehrenberg, 1831 and E. hentscheli Kahl, 1935. The description was based on the observation of living specimens and protargol impregnated specimens. This study is about redescription compared with original description. These species have not been reported in Korea and their characteristics are as follows: E. plicatilis is thin, long funnel form and has compact stalk, while E. hentscheli is unsymmetrical bell form and has hollow stalk.

Using the home made Kuhn type LB (Langmuir - Blodgett) film's deposition apparatus, We measured the displacement current of monolayer film on the water surface. The obtained displacement current had each different pattern by the kind of solution while varying pressure of the monolayer. Solution of 4 - octyl - 4' - (5 - carboxyl - pentamethyleneoxy ) - azobenzene (8A5H) and stearic acid (CH$_{3}$(CH$_{2}$)$_{16}$COOH) (C18) were spreaded at the air water interface respectively, and the current induced by the dynamic behavior of molecules were pressed by barrier. Displacement current of 8A5H measured small current than C18 at same condition and it was positive direction when increasing pressure but it was negative direction when decreasing pressure. Also, Two patterns of displacement current were symmetrical form and appeared repeatedly. The C18 has unsymmetrical form of displacement current and weak current when decreasing pressure (expansion). The C18 molecules have two distinct peak values of displacement current that show that the orientations of molecules were changed largely at this points. From these results, we obtained that the 8A5H has more elasticity than the C18.8.C18.

The purpose of this study was to examine what consumers virtyally thought about deconstructional method used in fashion and its cloths. For attaining the purpose, earlier studies were reviewed to see what kind of deconstructional methods were used in fashion and its cloth, and questionnaire survey was carried out based on the result. 10 kinds of deconstructional method were surveyed : indeterminate form, lingerie look, layering, unsymmetrical form, seethrough cloth, slash or making a hole, fray, padded cloth, patchworked cloth, and wrinkled cloth. There appeared 6 kinds of image for deconstructional fashion, esthetics, womanliness, youth, elegance, uniqueness, and fashionability. Consumers considered most deconstructional fashion to be unique but unique but lack elegance. However, they didn\`t feel indeterminate form, fray or padded cloth was unique, and one notable thing was that they had an impression wrinkled cloth was graceful. The design assessed to be generally esthetic was lingerie look, laying, seethrough cloth and wrinkled cloth. Those who were older set more esthetic value on layering, seethrough cloth, fray, padded cloth and wrinkled cloth. On the contrary, they didn\`t have a good impression from slash, making a hole or patchworked cloth. As a result of investigating the subjects\` willingness to wear deconstructional design, there was deconstructional design which they might possibly put on, and those who were older found more difficulties in wearing ir. Toward indeterminate and layering fashion, younger people whose age was ranged from 18 to 22 or from 18 to 22 or from 23 to 27 showed particularly better response. Married woman wanted to wear wrinkled cloth, and considered it possible to put on seethrough design more than unmarried women. Rather, younger people were more unwilling to wear seethrough design.

This paper investigates the cogging torque reduction in a brushless DC(BLDC) motor having an inner-rotor with surface-mounted segment-type permanent magnets. The kind of magnets for the BLDC motor could have different waveforms of magnetization such as square, trapezoidal and sinusoidal form. This paper discusses the effect of the unsymmetrical magnetization distribution in the segment-type permanent magnet, which is able to obtain through a segment structure that the number of poles per segments is 2 ($N_p/N_s$), on the cogging torque and EMF waveform. Where the existing magnetizer fixture for the square-type magnetization is used to magnetize the magnets in two segment structures of $N_p/N_s$ = 1 and 2. The effectiveness of the proposed designs had been confirmed by comparing cogging torque, and EMF waveform between conventional and new models which are analyzed by Finite Element Method (FEM).

The purpose of this study was to identify the aesthetic characteristics of modern fashion design use with a particular focus on transparency, and to help create future vision and feature. As part of the methodology for this study, I examined the concept of transparency, its characteristics and how it was expressed through art, architecture and other designs using literature research. Furthermore, I performed justifiable analysis on modern fashion design which used transparency from the 1990s till present. The following concepts were deciphered from information: Firstly, the concept of purity was highlighted. The emphasis here was to enhance the body's natural beauty with simple silhouettes that do not restrict its curves, using light materials such as clear vinyl, semi-clear materials or thin chiffon. Secondly, to express sensuality by exposing the body's curves with tight wrapping using clear materials, or with indirect and symbolic see-through techniques using contrasting clear, semi-clear and opaque materials. Thirdly, to express futurism through cyber and electronic images using high tech or shiny materials such as metal or holograms. Mechanical movements or effects of light are also used. Fourthly, to express playful characteristic by promoting surprises and disharmony that contradict with traditional techniques. This is carried out by intentionally exaggerating certain portions of clothes through disorder elements or confusion, and unsymmetrical shapes which destruct the human body's normal form.

In this study, we analyze the problem of wedge cracks, which are geometrically unsymmetrical in transversely piezoelectric materials. A single concentrated antiplane mechanical load and inplane electrical load are applied at the point of the wedge surface, while one concentrated antiplane load is applied at the crack surface. The crack surfaces are considered as permeable thin slits, where both the normal component of electric displacement and the electric potential are assumed to be continuous across these slits. Using Mellin transform method, the problem is formulated and the Wiener-Hopf equation is derived. By solving the equation, the solution is obtained in a closed form. The intensity factors of the stress and the electric displacement are obtained for any crack length as well as inclined and wedge angles. Based on the results, the intensity factors are independent of the applied electric loads. The electric displacement intensity factor is always dependent on that of stress intensity factor, while the electric field intensity factor is zero. In addition, the energy release rate is computed. These solutions can be used as fundamental solutions which can be superposed to arbitrary electromechanical loadings.
