  • The initial configuration for 95-seat passenger regional turboprop aircraft, the so called KC950, was designed to meet the market requirements. This paper prescribes the initial design based upon aircraft design guidelines and compared the competitive aircraft configurations after considering the related FAR 25 regulations. More specifically, results of design describe how to select the fuselage cross-sectional area, how to layout the cabin, and how to determine the overall shape and physical dimension of the fuselage. Sizing of wing and empennage areas is estimated using empirical equations and tail volume coefficients in this design. Some design guidelines to determine wing sweep angle, taper ratio, incidence angle and location are also introduced.

  • Emotional experience (James, 1884)[1] can affect people's behavior. There are few types of research on VR marketing(Maojun Zhou, Zeru Yan, 2018)[2] design based on emotional experience. This article is based on emotional evaluation theory and empirical research, and the VR marketing case "Buy+" online shopping platform (Wu Yongyi, 2016). It is concluded that there are three levels of emotional experience definition on VR marketing which decompose the features of the VR marketing design of "Buy+ as an online-shop" correspondingly and find out the design features of VR marketing from the perspective of emotional experience. Finally, through the analysis of the questionnaire data, it verified that vividness, functionality and effectiveness could represent the features of VR marketing design. Moreover, it analyzed the correlation among these factors. Vividness and functionality have the closest relationship among them. The definition, the components, and the correlation of the three-layer emotional experience obtained from this research can provide theoretical support and reference for other VR marketing designs.

  • The purpose of this study is to develop high-valued added socks by utilizing consumer design preference research in design. The study was performed by investigating literatures including previous studies, and researching the recognition and design preference of consumers. As a final step, socks designs were developed to reflect the results of the research. Gender differences have been found in the choice of socks. Women put more importance to the design, color and trend and prefer geometric, animals and plants patterns, and unique images compared to men. In terms of fashion interest level, 'high' group preferred design, color, and trend than 'middle' and 'low' group, and also preferred geometric, abstract patterns. Women's and unisex socks were designed for people in their 20s, the age group with the highest level of interest in fashion, after taking results of the consumer design preference research into account. Main themes for the lady's socks are 'Soft Shape' and 'Line Composition' in order to express delicate, soft sensibility. For the unisex socks, 'Daydreamer' and 'Free Zone' are the themes used to express young energy and the sense of freedom. 12 styles were developed by creating 3 styles per theme using Photoshop CS5 and Illustrator CS5 programs. As a result, it is confirmed that design strategies in segmented market are necessary for the high-valued added products. Also, the understanding of changes in consumer's tastes and needs through regular market research is needed for the competitive socks design planning.

  • The purpose of this paper is to develop instructional activity support model for capstone design in order for improving creative engineering education. To do this, having extracted the core idea of capstone design, and elicited core learning activity process, and grasped core supportive factors according to each core learning activity process that elicited, an improved instructional design model for capstone design was then developed through formative evaluation with respect to the draft of the instructional system development model for capstone design. As to major research methods, case analysis, requirements analysis through interview, and formative evaluation by experts were employed, and then research studies were undertaken. The formative evaluation by experts was carried out for two hours in 2007, and the experts participated in the evaluation consisted of total 6 persons: two specialists of capstone design contents, two professionals in field works, and two expert instructional designers in education engineering. Interview results had been reflected in this research when developing final instructional design model for capstone design. The core learning activity process of the final instructional design model for caption design, which developed in this research, comprises following stages: (1) Team building $\rightarrow$ (2) Integrated meeting between industry and academy $\rightarrow$ (3) Analysis of tasks $\rightarrow$ (4) Clarification of tasks $\rightarrow$(5) Seeking solutions for issues $\rightarrow$ (6) Eliciting priority of solutions $\rightarrow$ (7) Designing solutions and construction $\rightarrow$ (8) Exhibiting outcomes and presentation $\rightarrow$(9) Gaining comprehensive insights Also, in the core learning activity process, supportive factors that support implementation of each step were presented having been categorized into facilitator (teacher, and professionals in field works), learner and tool, etc.

  • This paper gives reviews on current research status in telecommunication network design. Two problems are identified as major research issues. One is the WDM network design problem, where traffic grooming, virtual topology design and routing and wavelength assignment problems are considered. The other is the OSPF weight setting problem which was proposed as a practical method to implement traffic engineering capability in IP networks. After presenting surveys on those problems, we discuss potential challenging research issues in telecommunication network design.

  • In this paper, we proposed the novel device and process design to enhance the uniformity of low-temperature poly-Si TFTs fabricated by sequential lateral solidification (SLS). The proposed design schemes can avert the conventional two-shot SLS process-induced issues. Moreover, different design considerations between conventional excimer laser crystallization and the SLS process were also proposed and discussed.
