A defect on the product safety display is defined by a failure to prevent the damage caused by the inappropriate explanation, direction, and caution to warn the users of the related risks. In other words, it lacks the sufficient instructions or caution for proper use and is unable to furnish the possible danger of the product and the instructions to deal with it. The defect is the responsibility of the manufacturers who are supposed to provide the adequate information so as to prevent injuries of the users. However, in order to prove the product safety display defective, there should be a comprehensive consideration in many different ways such as social norms (such as property and expectation of the product), usage form, indication of the expected risk, and awareness of consumer about the harm and possibility of avoidance of danger. The purpose of this research is to propose the content and types of standardized indication of safety in the industrial product by collecting and analyzing domestic safety information.

The kinematically admissible velocity field is developed for the analysis of extruded products. The curving of product in extrusion is caused by the linearly distributed longitudinal velocity on the cross-section of the workpiece at the die exit. In the analysis, the longitudinal velocity in extrusion direction is divided into the uniform velocity and the deviated velocity. In order to satisfy the requrement of the kinematically admissible velocity field, the average value of the deviated velocity should be zero. At the same time, it should linearly change with the distance form the center of gravity of the cross-section of the workpiece. The results of the analysis show that the curvature of product increses with increses in eccentricity of gravity center of the cross-section of workpiece at die entrance form that of the cross-section at the die exit.

The purpose of this study is to interpret the artistic nature of fashion from the point of view of George Dickie's Institutional theory of art, which defined art from a sociological context. Five notions to formulate the institutional definition of art were regarding the artist, work of art, public, artworld, and artworld system. These notions were applied to the fashion world, and they deduced the definitions of a fashion designer, a fashion product, a fashion consumer, and the fashion system, which indicated fashion's social status in the art system. Firstly, a fashion designer plays a collective role in the product with an understanding of the consumers, professional knowledge of the design, and knowledge of making images of fashion products. Secondly, a fashion product involves artifactuality in the form of clothes created by collaboration among producers and it is transformed into fashion by collective activity of distributors and consumers. Thirdly, a consumer is a set of people who play a leading role in the assessment and consumption of the fashion product, allow the fashion designer to read his or her taste and reflect it in the fashion product although they are not directly involved in its production. Fourthly, a fashion system is a social framework for the presentation of a fashion product by a fashion designer to a consumer, and a social institution which enables clothes to transform into fashion through design, production, display, distribution, and sales. As a result, fashion is defined as an artifact in the form of clothes created by a fashion designer and presented to a consumer by the fashion system.

In this paper, based on an augmented Lyapunov-Krasovskii functional(LKF) with time-delay product quadratic terms, the stability result in the form of linear matrix inequality(LMI) is proposed. In getting an LMI result, the free matrix based integral inequality is used. Finally, two well-known numerical examples are given to demonstrate the usefulness of the proposed result.

We provide the set of left-invariant minimal unit vector fields on the semi-direct product $\mathbb{R}^n\;{\rtimes}_p\mathbb{R}$, where P is a nonsingular diagonal matrix and on the 7 classes of 4-dimensional solvable Lie groups of the form $\mathbb{R}^3\;{\rtimes}_p\mathbb{R}$ which are unimodular and of type (R).

The objective of STEP is to provide neutral mechanism capable of describing product data through the life cycle of a product, independent form any particular systems. This paper describes an STEP application program that can display the three-dimensional shape based on b-spline surface and the data which defines configuration of the product. The developed program is based on the STEP part 203 “Configuration controlled design”.

We study the space-times that have a unique terminal indecomposable past set or a unique terminal indecomposable future set and examine their causal boundary, and we investigate some conditions for the warped product space-times of the form (a, b) ${\times}_fF$ to have a unique terminal indecomposable past set or a unique terminal indecomposable future set.

In this paper, we use an infinite dimensional conditioning function to define a conditional Fourier-Feynman transform (CFFT) and a conditional convolution product (CCP) on the Wiener space. We establish the existences of the CFFT and the CCP for bounded functions which form a Banach algebra. We then provide fundamental relationships between the CFFTs and the CCPs.

The polymorphism of biphenyl dimethyl dicarboxylate was investigated by DSC. From product five crystal forms. Form 1, Form 2, Form 3, Form 4, and Form 5, were characterized and three crystal forms. Form 6, Form 7, and Form 8, were prepared with the recrystallization method. The dissolution patterns of these eight crystal farms were also studied, but there was practically no difference in dissolution rate.
