The purpose of this study is to examine the political and social statements through fashion design, by comparing with more activated statements in the general design area. To achieve this, the documentary study and practical case study have been executed. First of all, the meaning of design politics was defined and the cases of design practice of political and social statements were reviewed and classified historically. Traditionally, designs have been inextricably linked with political authorities and ideologies. As propaganda, it has been used for power authority to seize power and maintain dominance. On the contrary, they could be an instrument to resist and criticize against contemporary power authority and dominant. Next, the political and social statements were traced historically through fashion design on the basis of the two previously reviewed categories. And then, comparing political and social statements between design and fashion design, the contents and ways of their expressions were similar. In design, there were more various ways when the designers were leading collective behavior, but in fashion design, there were more leading voices of socio-political organizations and resistant counter culture groups. Now, new trends are rising constantly where individual designers' creations express many different socio-political beliefs. This study which inquires designers' political and social involvement will be helpful in making people rethink the social role of fashion design and encouraging conscious fashion design activism.

Purpose While individuals have unique abilities for planned behavior, they also often act irrationally. In this study, we draw on myopic loss aversion perspective as a meta-theoretical lens to explain why mobile applications users have inertia from updating their applications, ultimately leading them to use current version of applications. Design/methodology/approach Based on a survey of 219 users, this study conducts its research model using partial least square analysis and also demonstrates that both subconscious triggers (habit and anxiety) of system 1 thinking and conscious triggers (sunk cost and transition cost) of system 2 thinking promotes user's inertia, thus leading to the willness to continue use current versions. Findings By grounding the research model in the combination of both status quo bias and dual information processing theory from the behavioral economics, this study provide an alternative theoretical lens to describe why mobile users hesitate to update their applications. The results of this research show that all triggers have significant impacts on inertia. This study also found that the relationship between inertia and willingness to continue to use current version was positively significant.

The flow instability in a low specific speed mixed-flow pump, having a positive slope of head-flow characteristics was investigated. Based on the static pressure measurements, it was found that a rotating stall in the vaned diffuser occurs at about 65% flow rate of best efficiency point (BEP). A dynamic Particle Image Velocimetry (DPIV) measurement and the numerical simulations were conducted in order to investigate the flow fields. As a result, the diffuser rotating stall was simulated even by Computational Fluid Dynamics (CFD) and the calculated periodic flow patterns agree well with the measured ones by DPIV. It is clarified that a periodical large scaled backflow, generated at the leading edge of the suction surface of the diffuser vane, causes the instability. Furthermore, the growth of the strong vortex at the leading edge of the diffuser vane induces the strong backflow from the diffuser outlet to the inlet. The scale of one stall cell is covered over four-passages in total thirteen vane-passages.

Purpose: The purpose of this study was to conduct a grounded theoretical analysis on the hospital accreditation experience of head nurses in order to understand their behavior on the adaption of this new system. Methods: The participants were 8 head nurses with more than 3 years of experience. The data were collected through in-depth interviews using audiotape recording analyzed by the constant comparative method described in Strauss and Corbin's methodology. Results: There were 113 concepts, 26 subcategories and 12 categories identified through the open coding process. In the axial coding, the following paradigm model was proposed: 1) the causal conditions were 'hardware problem' and 'software problem', 2) the contextual conditions were 'vertical relationship', 'individual preference', and 'family support', 3) the intervening conditions were 'passive conditions' and 'active conditions', 4) the action/interaction strategies were 'leading role' and 'dependent role', 5) the consequences were 'positive acceptance' and 'negative acceptance', 6) the central phenomenon was 'difficult situation' and 7) the core category was 'leading in harmony'. Conclusion: The new system led head nurses having difficulties as the middleman between the hospital administration and general nurses, but they made a continuous effort to overcome and adapt to it through a number of strategies.

According as the industry was developed, the pollution of the environment and atmosphere rose up to the surface. So, the focus is now concentrated on the engines of affinity for nature. And the investigators make more effort to the improvement in the performance of engines, depending to the prices of oil and the anxiety about the exhaustion of the fossil fuel go up. So the GDI engines head up for these necessities. In this experimental study, the spray flow characteristics for a commercial injector equipped in the present GDI engine were investigated, which had a strong influence on the engine performance and emissions. The experiment was performed at the injection pressures of 1, 3, 5 and 7MPa under the atmospheric condition. A PDPA system was used to specify the flow characteristics of the spray. Also, the global spray behavior classified into three regions as leading, main spray and vortex cloud region, was analyzed by using a visualization system. And the regions were compared with each other.

In this paper, a new model-based Fault Detection and Diagnosis (FDD) method for an agile supersonic flight vehicle is presented. A nonlinear model, controlled by a classical closed loop controller and proportional navigation guidance in interception scenario, describes the behavior of the vehicle. The proposed FDD method employs the Inertial Navigation System (INS) data and nonlinear dynamic model of the vehicle to inform fins damage to the controller before leading to an undesired performance or mission failure. Broken, burnt, unactuated or not opened control surfaces cause a drastic change in aerodynamic coefficients and consequently in the dynamic model. Therefore, in addition to the changes in the control forces and moments, system dynamics will change too, leading to the failure detection process being encountered with difficulty. To this purpose, an equivalent aerodynamic model is proposed to express the dynamics of the vehicle, and the health of each fin is monitored by the value of a parameter which is estimated using an adaptive robust filter. The proposed method detects and isolates fins damages in a few seconds with good accuracy.

An analytical expression for the turbulent burning velocity is derived from the asymptotic zone conditional transport equation at the leading edge. It is given as a sum of laminar and turbulent contributions, the latter of which is given as a product of turbulent diffusivity in unburned gas and inverse scale of wrinkling at the leading edge. It was previously shown that the inverse scale is equal to four times the maximum flame surface density in the wrinkled flamelet regime [1]. The linear behavior between $U_T$ and u' shows deviation with the inverse scale decreasing due to the effect of a finite flamelet thickness at higher turbulent intensities. DNS results show that $U_T/S^0_{Lu}$ may be given as a function of two dimensionless parameters, $u'/S^0_{Lu}$ and $l_t/\delta_F$, which may be transformed into another relationship in terms of $u'/S^0_{Lu}$, and Ka. A larger $l_t/{\delta}_F$ or a smaller Ka leads to a smaller scale of wrinkling, hence a larger turbulent burning velocity in the limited range of $u'/S^0_{Lu}$. Good agreement is achieved between the analytical expression and the turbulent burning velocities from DNS in both wrinkled and thickened-wrinkled flame regimes.
