In this study, the effects of show host's verbal communication subfactors, such as paralanguage, friendliness, and professionalism, as well as nonverbal communication subfactors, such as demonstration attitude, appearance, and attractiveness, on purchase intention were examined by evaluating customer empathy and product reliability. Data was collected from 20s-50s females. SPSS 23.0 and AMOS 23.0 were used for data analysis. The results revealed that professionalism and friendliness had a positive impact on customer empathy; however, friendliness had a negative impact on product reliability. Moreover, nonverbal communication subfactors had a positive impact on empathy, and appearance had a positive impact on product reliability. In contrast, attractiveness had a negative impact on product reliability, whereas empathy and product reliability had a positive impact on purchase intention. Thus, ensuring appropriate verbal and nonverbal communication is essential for customer empathy and product reliability. Given that a show host's friendliness, professional verbal communication, demonstration attitude, appearance, and attractiveness have a positive impact on customer empathy, these factors should be considered critical qualities of show hosts.

급속도로 발전한 컴퓨터 환경하에서 사용자는 훨씬 더 편리하고 손쉽게 컴퓨터를 다룰 수 있게 되었다. 그러나 이와 대조적으로 지금까지의 프로그램 개발과정은 프로그래밍 언어의 숙달을 요구함으로서 전문적인 교육을 받은 소수의 프로그래머만이 할 수 있는 분야가 되었다. 이에 본 논문에서는 직관적인 사용자 인터페이스를 기반으로 하여 프로그래밍 언어를 모르는 사람들도 자신의 필요에 적합한 프로그램을 직접 작성하여 활용하는데 도움이 되는 시스템의 개발에 필요한 기반기술을 제시하고 구현된 시스템의 전체적인 윤곽을 제시한다.

Corporate design activities have expanded from being exclusive and passive responsibilities to active participation in planning, marketing, technology and corporate brand image differentiation for successful business. Thus the communications between designers and other functions come to include critical decision making, information sharing, and objective reasoning. Given that design activities now have to involve various functions in product development, the styling-related design process, which is still developed by designer's intuition and experience, poses as an obstacle not just between various functions involved, but even within the design function. To overcome this obstacle and to lead more effective design decision process, a means for product form development assessment and management is necessary. This research proposes a foundation for managing and assessing product form based on the hypothesis and demonstration of discovering a system of formative factor and order a product form expresses that can be shared as an objective and logical system. As a result of this demonstration, the form as a unique visual expression and the factors related to the form and its co-relationship are examined. The factors are called formative parameters and the system is named as the product form alignment method. Based on the logic derived from the system, the process for developing an image that aligns with the predefined goal is explained. The method defines a balance between a designer's intuitive creativity and the extracted logic, which can act as a basis for designers to share design language among themselves and for communication between design and other functions. Based on this system, designers are able to align design work with the set goal, and focus and limit the range of form development, which is anticipated to result in lead-time reduction and minimizing unnecessary obstacles and mistakes.

This paper proposes a virtual storage system for smart home/office embedded devices by utilizing AoE and HyperSCSI protocols. It relies on current Ethernet infrastructures and aims to provide a low-cost solution for the storage limitation problem on embedded devices. We choose AoE (ATA over Ethernet) and HyperSCSI in our implementation because they are relatively lightweight compared to other network storage protocols such as NFS(Network File System), CIFS(Common Internet File System) and iSCSI(internet Small Computer System Interface). The design and architecture of our proposed virtual system as well as the prototype demonstration are presented in this paper.

The present study aims to design a multiplayer microstrip antenna with composite sandwich construction and to estimate structural behavior of this multiplayer structure for the next generation of structural surface technology. This is termed Surface-Antenna-Structure indicating that structural surface becomes antenna. Constituent materials were selected considering electrical properties as well as mechanical properties. For the antenna performance, antenna elements inserted into structural layers were designed for satellite communication at a resonant frequency of 12.5 GHz and final demonstration article was $16\times16$ array antenna. From electrical measurements it was shown that antenna performances were in good agreement with design requirements. Structural analysis showed this antenna structure was well designed for the mechanical rigidity. All constituent materials were characterized independently. The SAS concept is the first serious attempt at integration for both antenna and composite engineers and promises innovative future communication technology.

This paper describes a design method and characteristics analysis of the 3 kW grid-connected photovoltaic power generation system to establish the basic application technology of photovoltaic systems. The design specification of a 3 kW photovoltaic power generation system including a DC/AC inverter is suggested to investigate the system performance for grid connection. The results of the demonstration test from February to October show that the system with utilization rate up to 17% has reliable operation characteristics and is useful for peak-shaving of utility power.

A computer simulation methiod for costume design has been developed using LUMENA, a generic-purpose 2-dimensional graphic software. In this study the palette, tone chart, fabric chart, styling chart, and costume drawing were constructed on the computer. In costume design simulation, fabric swatches with various colors and patterns were applied to the base garment image taken by using a scanner or a video camera. In this procedure the original 3-dimensional effect was fully retained. Using this simulation method, a number of costume designs could be carried out in short time without actually making the garment. A portfolio including the tone chart, fabric chart, styling chart, costume drawing, and simulation results were made for the purpose of demonstration, using the animation tools of LUMENA.

Since the time, cost and lack of regulatory information and guidance, one of the largest regulatory obstacles for an airframe manufacturer of polymer based advanced composite materials in certified aircraft applications, is to generate design allowables that will satisfy Airworthiness Regulations. In the past two decades, the design allowables used in military aircraft had been generated and applied in Korea, however the qualification of composite materials used in certifying airframe structure was not accomplished for design and demonstration of compliance to applicable airworthiness regulation. It is the intend of this paper that provide the basis of composite material qualification for small aircraft certification to the airworthiness regulation.
