The purpose of this paper is to develop and test a conceptual model of purchase intentions, positive emotion, and e-servicescape that is defined as the online environment factors that exist during service delivery. Survey research method was used to gather data regarding consumers' perceptions of e-servicescape. Surveys were administered to 681 college students who experienced purchasing fashion products on the Internet. The results showed that e-servicescapes perceived by fashion consumers were composed of three dimensions: (1) Aesthetic appeal, (2) Ambient conditions, and (3) Layout & functionality. These dimensions of e-servicescape influenced consumers to lead positive emotions and purchase intentions. Additionally, positive emotions constituted a key variable for the purchase intention of fashion products during online exchange. The study revealed that consumers' interpretations of online environments exerted a powerful influence over positive emotion and purchase intentions. Also, it strongly endorsed the view that the purchase intentions of customers were linked to the extent to which they feel positive emotions by the e-service provider. This study provides insights into how consumers' interpretations of e-servicescape affect their subsequent positive emotions and ultimately their intentions to purchase. The findings of this study also have numerous implications for both services managers and internet developers related to fashion products.

This study was conducted to evaluate the usability of serious-game apps for robots that are being developed for hospitals to add familiarity to hospital life for hospitalized patients. We conducted a usability test of 10 experts and 12 elementary school students with inpatient experience. The usability evaluation of the developed apps was based on the professional (MARS) evaluation tool and the user (uMARS) evaluation tool. The results of the usability test of the serious game robot app were $3.67{\pm}0.342$ for professionals and $3.68{\pm}0.592$ for children. The expert group obtained the highest score in the aesthetics category, and the user group obtained the highest score in the functionality category. In the subjective comments, the experts pointed out the game layout and the consistency of the style. According to the children, the methods were easy to learn, and the screen movement was mainly described. Both groups received low ratings in terms of engagement through participation. This study will provide useful reference material when the functional game app is actually installed in the robot and the usability test is conducted again after the results obtained in this study are considered.

A systematic development process for the low noise FEAD (Front End Accessory Drive) system is presented by combining CAE (Computer Aided Engineering) and the experimental rig test. In the estimation of the belt drive noise, two main difficulties arise from the high non-linearity due to the stick-slip contacts on the interfaces of the belt and pulleys, and the interaction of the belt drive system with the powertrain rotational parts. In this work, a recently developed analysis method of the belt drive has been employed considering powertrain rotational dynamics. As results, it shows good correlation with the vehicle tests in various operational modes. The established model has been employed to validate the new design improving the stick-slip noise of the problematic FEAD system. Furthermore, the best proposal of FEAD system in terms of functionality [NVH (Noise, Vibration and Harshness), fuel economy, cost. etc.] has been suggested in the concept design stage of new engine through this presented methodology.

This study intends to analyze the various spatial structures and characteristics of the museum based on the two of the Renzo Piano's recent projects Menil Collection '||'&'||' Museum and Beyeler Foundation Museum Which defined the direction of the "Third Generation" in museum architecture with reference to the quality of spatial experience and design applications. Comparison and analysis were done on the basic spatial organization floor layout accessibility exhibition area lighting plan and circulation between the two museum. Through the itemized common characteristics of the museum the architect's proposal on meaning and direction of the new museum architecture can be viewed. The contemporary museums distinguish themselves quite clearly from their predecessors and this applies both to their own form and to their spatial organization. As the public demands and requests toward the museum building facility expand everyday the architect must respond by providing multiple types of space where people can experience different atmosphere in each area. One concept he used to create multi experienced area was manipulation of the natural light using by the state-of-the-art techniques of the light filtering system and multi-layering roof system to protect the valuable collections against the direct sunlight. But mainly it was to prove his strong belief in "architecture of light" by creating space with minimized meaning by purposely distinguished area in order to provide maximum support to the physical value of the collection " The connection with nature" is another concept which Piano used to provide the public a tranquil experience through out the architecture which engages in a lively dialogue with art. In spatial organization Piano concerned on functionality which not only concentrated on the visitor's point of view but also on the museum staff's comfort. Unlkie the traditional museum he alternates various size of exhibition areas for spatial hierarchy. Specially the spatial flexibility that the temporary exhibition areas are able to be expanded to the permanent exhibition areas by adjoining t재 spaces differentiate Piano's new museum from the rest. museum from the rest.

In this paper, the activities carried out within the EU funded Clean Sky Joint Technology Initiative (JTI GRA) Project and aimed at developing a morphing flap, are illustrated. The reference device is a regional aircraft single slotted flap, enhanced with deforming capabilities to obtain improved hyper-lift performance. The design started with the identification of the internal architecture, intended to allow camber variations. A concentrated-hinge architecture was selected, for its ability to fit different curvatures and for the possibility of easily realizing an "armadillo-like" configuration, then avoiding the use of a complicate deformable skin. The flap layout is made of segmented ribs, elastically hinged each other and span-wise connected by conventional spars. Relative rotations of the rib elements are forced by SMA structural actuators, i.e., cooperating in the external loads absorption. Super-elastic SMA are used to make up recovery elastic elements, necessary to regain the original shape after activation. These further elements in turn contribute to the overall flap rigidity. After assessing the hinge number and the size of the SMA active and passive elements, the advanced design phase was dealt with. It was aimed at solving manufacturing issues and producing the executive drawings. The realized demonstrator was finally tested in lab conditions to prove its functionality in terms of whether target shape actuation or attained shape preservation under loads. On the basis of the numerical results and the experimental outcomes, precious hints were obtained for further developments of the concept.

This paper represents an simplified design method of hybrid composites. The proposed method is very simple compared to conventional design approaches and easy to apply to practical design problems. The method is based on not complex optimization approaches but conventional theories. The equivalent dielectric properties concept and multi-layered dielectric slab theory are an important theoretical background of the proposed method. This approach divide the design domain into several domain which have theoretically different electro- agnetic functionality. Then, the domains are expressed by equivalent dielectric properties. Numerical analysis are performed several types of design candidates. S-parameter test for final design was conducted for validate the proposed approach indirectly.
