This paper proposes a mathematical model for web site service quality evaluation, which first applies analytic hierarchy process(AHP) to determine the weights of evaluation indexes of web site service quality and then analyzes web site service synthetically by means of fuzzy methodology. In this case, experts' knowledge cannot only be used but its subjective component can be eliminated. Hence, the web site service quality can be analyzed and evaluated more reasonably. After establishing this model, the experiment results will be given, which verify the feasibility and validity of the proposed model. The model proposed here is very simple and easy to implement and can provide a useful way to help developers evaluate their web site service quality efficiently.

Elman Discrete Recurrent Neural Networks Model(EDRNNM) was used to be a suitable short-term hydrological forecasting tool yielding a very high degree of flood stage forecasting accuracy at Musung station of Wi-stream one of IHP representative basins in South Korea. A relative new approach method has recurrent feedback nodes and virtual small memory in the structure. EDRNNM was trained by using two algorithms, namely, LMBP and RBP The model parameters, optimal connection weights and biases, were estimated during training procedure. They were applied to evaluate model validation. Sensitivity analysis test was also performed to account for the uncertainty of input nodes information. The sensitivity analysis approach could suggest a reduction of one from five initially chosen input nodes. Because the uncertainty of input nodes information always result in uncertainty in model results, it can help to reduce the uncertainty of EDRNNM application and management in small catchment.

This paper firstly introduces a classification model for designing the architecture of backup centers in terms of business continuity management. We propose that the replication solution, the level of disaster recovery, and the outsourcing style as three important factors that help explain the architecture of backup centers. We provide the details of each factor of the model and apply them to the real world cases of backup centers in Korea. We conclude that the model is well fitted to many cases of currently available backup centers and can provide backup center architects with a well classified architecture model with specific guidelines.

The purpose of this study was to develop a pragmatic fashion internship program as a following study of 'An analysis of the consciousness of the professors and college students for the fashion industry internship'. The methods of the quantitative analysis and some case studies were used for this study. The results of this study were as follows : Internship program has 6 steps ; ready, introduction, selection, operation, reputation, management. It will help professors and college students to execute the program systematically. The contents of the fashion internship program model for professors were as follows: 8 recruiting methods to find internship companies, the contents of the internship agreement, 6 types of internship, the contents of the recommendation letter, advanced education contents for a fashion internship, e-mentoring program model, a curriculum of the cultural study and the major course, evaluation standard elements of the intern students, the methods of evaluation etc.

This paper proposes empirical research areas and a curriculum model that outlines the core concepts of major research topic and educational programs of family business. The purpose of this study was two fold: First, to develop the conceptual and empirical research model of family business. For this purpose, this study examined five conceptual issues - ethical, theoretical, management, historical, environmental - in the development of family business research areas. Based on these five conceptual issues, this study developed an empirical research model of family business. Second was to develop the curriculum model of family business at the university level. This curriculum was developed in terms on the family system. business system, and ownership system of family business. This study will be useful in developing more professional curriculum and educational programs to help educator and professional advisors assist family businesses.

The basic goal of software development is to produce high quality software at low cost. Therefore, when to stop software testing and release the software product is a significant point in the software development. The software cost model is an effective tool used to help software developers control costs and determine the release time. In this paper, we discuss the cost model to apply all 6 models with consideration of time to remove errors, cost of removing each error and risk cost due to software failure. We show the impact of cost coefficients and parameter values on the expected total cost by changing the values and comparing the optimal release times.

In order to improve the safety performance oi construction projects, effective and corporative safety management program between head office and job site must be implemented. And its performance must be measured and analyzed for the identification of the problems in the safety management area. This study proposes a previous evaluation model of safety performance for the large construction firm in order to enhance their safety level. The fundamental data for proposed model is based on the past research(Son 2002), which is structured of evaluation criteria. weighted factor. statistical evaluation formula. The model would help the firm management in identifying the weak areas of safety performance in terms of the degree performing certain safety tasks. It is expected that the model could contribute to achieving the "zero accident" level.ot; level.

We examine whether country fundamentals help explain the cross-section of currency excess returns. For this purpose, we consider fundamental variables such as default risk, foreign exchange rate regime, capital control as well as interest rate in the multi-factor model framework. Our empirical results show that fundamental factors explain a large part of the cross-section of currency excess returns. The zero-intercept restriction of the factor model is not rejected for most currencies. They also reveal that our factor model with country fundamentals performs better than a factor model with usual investment-style factors. Our main empirical results are based on 2001-2010 balanced panel data of 19 major currencies. This paper may fill the gap between country fundamentals and practitioners' strategies on currency investment.

When a pedagogical agent system aims to provide students with interactive help, it needs to know what knowledge the student has and what goals the student is currently trying to achieve. That is, it must do both assessment and plan recognition. These modeling tasks involve a high level of uncertainty when students are allowed to follow various lines of reasoning and are not required to show all their reasoning explicitly. In this paper, the student model for interactive edutainment applications is proposed. This model is based on Bayesian Networks to expose constructs and parameters of rules and propositions pertaining to game and problem solving activities. This student model could be utilized as the emotion generation model for student and agent as well.

The most successful companies today are said to have strong brands. But what is a strong brand\ulcorner What makes a brand strong\ulcorner How do we build a strong brand\ulcorner This paper develops a customer-based brand equity model to help address these important questions. The developed model is a cause-and-effect model linking customer-brand relationships to rational and emotional brand associations, as well as rational and emotional brand evaluations. The customer-brand relationships are characterized by loyalty, based on both behaviour and attitude. As branding is a very complex concept, it is important to determine which of the many branding elements should be included in the model. This paper discusses why a given aspect is important for a brand's equity and which relations exist between the included variables from a theoretical perspective. The model provides insight into the creation of a brand's equity and can thus be used in the brand management process to achieve brand excellence.
