Since its introduction in Korea, design VE has widely been used as a means to enhance values in the construction industry. However, a greater emphasis is still placed on cost reduction in approach attitudes and performance evaluations on the implementation of design VE. In this regard, this study presented a performance evaluation method for cost, function, and value of VE proposals. Numerical criteria on the increase and decrease of cost and function that can classify the value enhancement type of VE proposals were proposed based on the performance evaluation method. It is expected that the use of numerical criteria for the type classification of VE proposal, and cost and performance evaluation method proposed in this study will make it possible to conduct a clear and more intuitive evaluation of VE proposal. However, it is appropriate to use the numerical criteria as a guideline to apply the new performance evaluation method for VE proposals. Therefore, it is necessary to conduct a statistical analysis with a wider range of users after the repeated application of the findings of this study, and thus to carry out research for presenting the numerical criteria for various types of users.

After arranging the general usability evaluation criteria of existing VUI researchers, this study verified how appropriate these criteria are for AI VUI specialized in navigation and the priority of their suitability. The VUI used in this study was analyzed through a survey from a total of 195 Chinese users after analyzing the navigation VUI used in China. As a result of the analysis, the usability evaluation criteria of the navigation VUI were extracted from three sub-factors of 'task accuracy', 'function satisfaction', and 'information reliability' in verifying conformance with general VUI evaluation criteria. With the recent advent of self-driving cars, safety and response speed are becoming very important, so Chinese users also ranked responsiveness as the top priority in VUI design, and the importance was also found to be high. Also, both men and women have the highest reactivity and the lowest multiplicity. VUI requires a convenient and natural interface to understand the intention between two objects through usability evaluation and verification in order to have effective interaction between humans and machines.

The cafeteria is one of the welfare facilities in the college and crowed with students during lunchtime because of the various menu, saying time and cheap price. In designing the cafeteria, we have to consider the users' needs and the factors which effect on their satisfaction and behavior under the pleasant environment. The purpose of this study is to draw the environmental improvement factors by Post Occupancy Evaluation. A survey about the users' actual condition and environmental satisfaction level and a behavior observation in the field were utilized as the study methode. The 150 copies of questionnaire were completed by students who ate at the cafeteria of W college in Daejeon city. The SPSS 15.0 for Windows was used for a statistical analysis. The results are listed below; two factors were drawn as the improvement elements through the combination of the unsatisfactory items obtained by the descriptive statistics and the influential items by the multi-regression analysis. They are images and approach. In the 'image' category, there us a statistical difference between the present image and prefer image. The users prefer much brighter, warmer, newer, more gorgeous, more cheerful, more clear, more active, more comfortable, and more modern image of cafeteria. In the 'approach', the location of ail existing cafeteria is inaccessible from the classrooms in spite of an important relationship between classrooms and cafeteria. Therefore the complementary plan for convenient approach is demanded for improvement of users' satisfaction.

IoT 환경의 최종 사용자 도메인에서 점점 더 많은 수의 지능형 M2M(Machine-to-Machine Communication) 장치가 애플리케이션 서비스를 생성하고 공유하기 위한 자원을 제공한다. 따라서 기존의 중앙집중식 서비스 제공자의 역할을 P2P 환경의 최종 사용자에게 이전하여 신뢰를 관리하는 것은 매우 유용할 수 있다. 그러나 최종 사용자가 독립적으로 서비스를 제공하거나 소비하는 비중앙집중식 M2M 컴퓨팅 환경에서는 상호간의 신뢰 구축이 가장 중요한 요인이 된다. 오작동하는 서비스를 구축하려는 악의적인 사용자들이 IoT와 같은 M2M 컴퓨팅 환경에서 보안문제를 야기할 수 있기 때문이다. 본 논문에서는 M2M 애플리케이션 서비스의 신뢰 평가를 위한 통합적인 분석과 접근방식을 제공하고, M2M 커뮤니티의 사용자들 사이의 신뢰도를 보장할 수 있는 최적화된 신뢰 평가 모델을 제시한다.

Evaluation of user interfaces has to be performed in an intuitive and subjective manner by experts especially when the problem comes to the complexity and consistency of sophisticated interface procedures. The manual analysis and evaluation of logical interfaces also tends to be slow and laborious. To make the evaluation more formal and objective, the criteria and the procedure with which the evaluation can proceed must be explicitly prescribed. Furthermore, to make the formal procedure as practical as subjective expert evaluation, the criteria must reflect the user knowledge of the target tasks since the task knowledge plays the role of a basis for users to understand the interface organizations and procedures. This paper describes ESTIM, a support system for task-based evaluation of user interface, that includes the interface evaluation criteria and implies an evaluation procedure. The support system can be used either in an interactive manner by the analyst during the evaluation or in an automatic evaluation mode. It was verified that the result of automatic evaluation by ESTIM matched the results of expert evaluation fairly well.

This study identified the characteristics of fashion rental service users as well as analyzed their purchase decision-making processes. A qualitative investigation was conducted through in-depth interviews with 13 women in their 20s-30s who have experienced renting fashion items due to a high interest in fashion. The results of the study are summarized as follows. The need recognition stage analyzed ventilation by mass media, SNS impact, curiosity, saving shopping time and money, awareness of situational necessity, and creation of various styles. The information search stage analyzed how users obtained information from 2 different sources of nonmarketer-dominated sources and marketer-dominated sources. The pre-purchase stage analyzed the evaluation of alternatives in which study participants used 2 evaluation criteria for fashion rental services and fashion rental items. The purchase stage analyzed how participants wait and select desired items (when receiving the notification of rentable items) or select alternative products. The consumption stage examined the usage frequency and usage method. The study divided the post-consumption evaluation stage into 2 categories for evaluation: personal feelings and service. The post-consumption behavior stage analyzed how participants displayed WOM, eWOM and purchase rental product behavior. Clothing shopping orientation of study participants is displayed in 5 dimensions of brand-seeking propensity, individuality-seeking propensity, economic efficiency-seeking propensity, rationality-seeking propensity, and pleasure-seeking propensity. This study identified three main characteristics in the study participants: interest in the fashion, favorable attitude toward used fashion items, consciousness of others.
