High quality-oriented consumers, new rationalism and concept-oriented consumption followed by high sensitivity fashion market are embossing the importance of fashion M.D. This study has a purpose to make practical and general approach to consumers' taste, trend receptivity, the propensity to consume, and how they are practically connected with market strategy. As a results of this study, First niche market, targeting a new consumer group, is embossed as consumers have new fashion lifestyle. Second, we need a strategy to fractionize fashion by developing concepts suitable for consumers' each scene, not by following radical trends for mature consumers. Third, to satisfy consumers' propensity to originally, we need to establish the identity of Korean original goods which can compete with world-famous brands.

Laundry has traditionally been regarded as one of the most demanding household chores, but the introduction of smart washing machines is changing this perception. Although smart washing machines have been on the market for several years and consumers' perceptions of washing machines have changed, little is known about consumers' perceptions of smart washing machines. The purpose of this study is to determine what users expect from smart washing machines. We conducted two focus group interviews with sixteen participants who had used smart home appliances to acquire qualitative data. Stimuli created by the interviewees were applied in the focus group interviews to collect more insightful data. We analyzed the data using the three-step method and QSR NVivo. Analysis revealed ten categories of predictive expectations, including seven utilitarian attributes (i.e., smart functionality, smart user interface, reliability, controllability, interactivity, functional value, and economic value) and three hedonic attributes (i.e., fashionable value, psychological value, and social value). The results of this study have implications for the development of smart washing machines that would satisfy consumers by taking user expectations into account.

Recent advances in low-cost remote monitoring systems have made it possible and practical to perform structural health monitoring (SHM) on a large scale. However, it is difficult for a single remote monitoring system to cover a wide range of SHM applications due to the amount of specialization required. For the remote monitoring system to be flexible, sustainable, and robust, this article introduces a new cost-effective, advanced remote monitoring and inspection system named DuraMote that can serve as a next generation supervisory control and data acquisition (SCADA) system for civil infrastructure systems. To evaluate the performance of DuraMote, we conduct experiments at two representative counterpart sites: a bridge and water pipelines. The objectives of this article are to improve upon the existing SCADA by integrating the remote monitoring system (i.e., DuraMote), to describe a prototype SCADA for civil engineering structures, and to validate its effectiveness with long-term field deployment results.

Let {$V_{nk},\;k\;{\geq}\;1,\;{\geq}\;1$} be an array of rowwise independent random elements which are stochastically dominated by a random variable X with $E\|X\|^{\frac{\alpha}{\gamma}+{\theta}}log^{\rho}(\|X\|)\;<\;{\infty}$ for some ${\rho}\;>\;0,\;{\alpha}\;>\;0,\;{\gamma}\;>\;0,\;{\theta}\;>\;0$ such that ${\theta}+{\alpha}/{\gamma}<2$. Let {$a_{nk},k{\geq}1,n{\geq}1$) be an array of suitable constants. A complete convergence result is obtained for the weighted sums of the form $\sum{^\infty_k_=_1}\;a_{nk}V_{nk}$.

In-vivo and in-vitro MR Microscopy has been performed to investigate any differences in-between the normal and the abnormal skin layers. Noninvasively acquired images could provide the skin histology. Also, it was found that the epidermis of the abnormal skin was thickened more than that of normal skin. MR Microscopy utilized for the present study may be applicable to the noninvasive investigation of skin pathology and this technique may be of use in the development of cosmetics.

There are many methods of obtaining butadiene described in the literature. In the america it is produced largely from petroleum gases, i.e., by catalytic dehydrogenation of butene of butene-butane mixtures. Butadiene can be recovered from the $C_4$ residue of an olefin plant by distilling off a fraction containing most of the butadiene, catalytically hydrogenating the higher acetylenes to olefins and separating the product from other olefins and isobutane by extraction. Also it can be obtained by cracking naphtha and light oil. Among the individual dienes of commercial importance, 1, 3-butadiene is of first importance. It is used primarily for the production of polymers.In the present paper, it was investigated for a effect of the formation and the growth inhibition of popped corn polymer in butadiene extraction unit. As a result of study, inhibitors, $NaNO_2$ and TBC were good effective for inhibition of the formation and growth in popcorn polymer. The rational formula of popcorn polymer obtained was $(C_4H_6)_x$.

An efficient sampling method of computer simulation is reviewed. Using the method, several thermodynamic states can be investigated at a time in a single simulation. It is due to the ability of the method to explore the relevant parts of configuration space equally for every state being investigated. The method can be used in simulations of complex systems such as biopolymers which are still greatly hampered by the multi-minima problem. In this article I present a brief theoretical review of the method and illustrate how to realize it in the simulations.

In-vivo and in-vitro NMR Microscopy has been performed to investigate the histological and/or pathological difference between the normal and the abnormal skin layers. The acquired images in the present study were able to provide the information of both the relaxation changes and the histological changes due to skin abnormality. The present study is also intended to show the possibility of NMR Microscopy application to both the noninvasive investigation of skin pathology and the helpful use in the development of cosmetics.

This study investigates ethical fashion consumption factors and corporate social responsibility (CSR) factors to segment consumer groups by ethical fashion consumption (EFC) and identify differences of EFC groups in the perception of CSR and demographics. I surveyed 390 people over age 20 in February and March, 2017. Data were analyzed with factorial analysis, cluster analysis, ANOVA, LSD, Chi-square, Cronbach's ${\alpha}$, using SPSS 20.0. The survey showed. 1) Five EFC factors (boycott/active purchase, donation/environmental protection, saving, legal consumption, and recycle) were extracted. 2) Four CSR factors (responsibility for stakeholder, ethical/environmental responsibility, social/charitable responsibility, and economic responsibility) were extracted. 3) EFC consumers were classified into four segments (low ethic, recycle, legal, and high ethic). 4) The perception of CSR factors was different among EFC groups. 5) The distribution of age level, education level, occupation, monthly purchase cost of clothing, and religion were different among EFC groups.
