PURPOSES : The accuracy of travel time information is a key measure of effectiveness and reliability of advanced traveler information systems. This study aims at investigating drivers' perception on the acceptable level of information accuracy and their corresponding valuations. METHODS : A questionnaire survey was executed for collecting driver perception data to capture the expectation level of travel time information provided and their willingness to pay for the information. A Tobit model was adopted for exploring the relationship among the acceptable level, driver socioeconomic characteristics and travel attributes. Since drivers' willingness to pay for accurate travel time information can be different according to their travel lengths, a piecewise linear regression model was developed to capture the sensitivity of values of travel time information to travel length. RESULTS : The analysis results suggest that trip purpose and travel time are two dominant factors to determine drivers' acceptable level of travel time information. For business and short trips, drivers want more accurate information than for non-business and long trips. Drivers' willingness to pay for travel time information also varies depending on their incomes, trip purposes and travel lengths. The results also show that drivers' valuation of travel time information provided is sensitive to their travel length. For longer trips, drivers are less sensitive to travel time information and then put less value on the information provided. CONCLUSIONS : Censored nonlinear regression models are developed to estimate drivers' acceptable accuracy for travel time information and their valuation using questionnaire survey data. The findings on drivers perception to the required accuracy of travel time information and their corresponding willingness to pay can be used in the design and deployment of advanced traveler information system to improve its effectiveness and usefulness through high compliance.

This study provides the basis far salesman to present formal style in suggesting Good-Bad formal style as well as in examining a meaning structure and valuation differences of visual valuation. Stimulus pictures has been chosen consequently 76 pieces through the preliminary inquiry who are working at department store, franchise salesman, car salesman, insurance staff and other salesmen. The tool for visual valuations about suit style is composed of 7 points of Likert type by making 21 questionnaires from the preliminary study. Collecting data is 512 pieces are used to analyse. The duration to collect data was from August 5th to 20th in 2004 and SPSS statistics package program has been used. At first, main factors according to the visual valuation of formal style are Attractiveness, Having abilities, Uncomfortableness. In second, Good formal style shows more attractive and looks having more abilities than Bad formal style and less uncomfortable. In third, in the relations of Good-Bad formal style and demographics, there is meaningful differences according to gender, age, job, salary. In fourth, in the relations of a purchase purpose and visual valuations of formal style, for Good-Bad valuation, the first impression is the most important factor and it is likely to be related to the purchase purpose, on the other hand, the purchase purpose has related to impression the most.

Brownfield redevelopment is relatively a new area of interest for federal and local government in the U.S. In the past years, there are continuing interests by urban planners, policy makers and scholars in the effects of neighborhood amenities on brownfield. This paper intends to introduce brownfield redevelopment efforts and assess the approaches to implement such efforts by reviewing current federal legislation in the U.S. for brownfield, especially in the case of the Seattle Region. This paper provides an understanding of the brownfield phenomenon, statutory dilemmas, barriers and strategies of brownfield redevelopment. This paper also addresses the need of more policy adoption and implementation for successful brownfield redevelopment.

The purpose of this study was to find the methodology of design plan that could raise the brand power by looking around the driving force of the design innovation through the case study of Louis Vuitton which has been evaluated to be successful in brand revolution by designer Marc Jacobs. Research methods were theoretical studies looking for various analysis and valuations about Louis Vuitton's design innovation and analysis about articles in International Herald Tribune and New York Times. Driving force of Louis Vuitton's design innovation could be summarized as designer's creativity and full supports for designers, establishment of BI by strategic cooperation between design and marketing parts, active design plans by collaboration with modern artists, existence of Logo as a symbol of brand, business mind pursuing adventures and dreams, and directors' artistic sensitivity and supports for culture and art.

Wireless data communication (WDC) services are increasingly penetrating the market. The two main alternative WDC technologies are wireless LAN and mobile Internet. Services based on these technologies display differences in quality attributes such as terminal device, data transmission speed, pricing scheme and so on. How consumers choose between these two alternatives will be determined by their preferences regarding such quality attributes. In turn, their preferences will affect the evolution of WDC services and related technologies. This study employs a conjoint analysis of consumer valuations of quality attributes of wireless LAN and mobile Internet services. Respondents rate hypothetical service alternatives featuring various combinations of quality attributes. By estimating consumer willingness to pay for the attributes of WDC services, the authors predict the evolution of WDC services and related technologies along various quality dimensions, make a comparison with the results of a previous study, and draw policy implications for national-and company-level R&D strategies.

A valued field (K, ν) is called defectless if each of its finite extensions is defectless. In [1], Aghigh and Khanduja posed a question on defectless extensions of henselian valued fields: "if every simple algebraic extension of a henselian valued field (K, ν) is defectless, then is it true that (K, ν) is defectless?" They gave an example to show that the answer is "no" in general. This paper explores when the answer to the mentioned question is affirmative. More precisely, for a henselian valued field (K, ν) such that each of its simple algebraic extensions is defectless, we investigate additional conditions under which (K, ν) is defectless.

This paper aims to propose a Comprehensive Decision Support Model to evaluate retail companies' financial performance traded on the Vietnam Stock Exchange Market. The financial performance has been examined in terms of the valuations ratios, profitability ratios, growth rates, liquidity ratios, efficiency ratios, and leverage ratios. The data of twelve companies from the first quarter to the fourth quarter of 2019 and the first quarter of 2020 were employed. The weights of 18 chosen financial ratios are calculated by using the Standard Deviation method (SD). Grey Relational Analysis technique was applied to obtain the final ranking of each company in each quarter. The results showed that leverage ratios have the most significant impact on the retail companies' financial performance and gives some long-term investment recommendations for stakeholders and indicated that the Taseco Air Services Joint Stock Company (AST), Mobile World Investment Corporation (MWG), and Cam Ranh International Airport Services Joint Stock Company (CIA) are three of the top efficient companies. The three of the worst companies are Viglacera Corporation (VGC), Saigon General Service Corporation (SVC), and HocMon Trade Joint Stock Company (HTC). Furthermore, this study suggests that the GRA model could be implemented effectively to ranking companies of other industries in the future research.
