  • Shieh and Wang [10] recently proposed an efficient mutual authentication scheme that combined the cost-effectiveness of operations of Lee et al. [6]. scheme and the security and key agreement of Chen and Yeh scheme. Shieh and Wang [10] scheme, however, does not satisfy the security requirements against a third party (the man-in the middle, attacker) that have to be considered in remote user authentication scheme using password-based smart cards. Shieh and Wang weaknesses are the inappropriateness that it cannot verify the forged message in 3-way handshaking mutual authentication, and the vulnerability that the system (server) secret key can easily be exposed. This paper investigates the problems of Shieh and Wang scheme in the verification procedure of the forged messages intercepted by the eavesdrop. An enhanced two-way remote user authentication scheme is proposed that is safe and strong against multiple attacks by adding the ability to perform integrity check on the server and proposed scheme is not expose user password information and the system's confidential information.

  • In this paper, the traceability system for rice which is based on RFID technology is introduced. The traceability system plays an important role in the quality management for rice and rice-related food since this system can provide the information of all food chain (production, treatment, distribution and sales etc.) and more quickly identify the cause of the rice and rice-related accident. The main result of the this paper is the basic structure for the traceability system based on RFID technology. To show the implementation case based on this basic structure, the effectiveness of the traceability system is verified. In addition, the prerequisites condition for effective implementation is proposed.

  • This study examined the effect of product presentation on consumers' affective/cognitive states and purchase intention. The design of the study was a one factor(product presentation: garment presented flat vs. garment presented on models without faces vs. garment presented on models with faces) between-subject design with a moderator (involvement: high vs. low). A sample of 429 female college students participated in this online experiment. The results show the effectiveness of using a realistic human model on apparel websites. Also, consumers who are highly involved with clothing generally exhibit more positive responses than those who are less involved. Overall, these findings provide empirical support for the Stimulus-Organism-Response model and the Elaboration Likelihood Model, and contribute useful knowledge regarding website design for online apparel retailers.

  • Effective and efficient selection of IT projects is crucial for company's competitiveness. The selection of IT projects usually involves consideration of budget constraints but existing IT project selection models often neglect budget constraints. This paper presents an IT project selection model which considers budget constraints. AHP(Analytic Hierarchy Process) and Knapsack problem model have been combined to develop the proposed model, AHP-K model, where AHP is used to estimate weights of selection criteria and, then, a knapsack problem model is utilized to optimize selection of IT project while meeting the budget constraints. In this paper, a case study is provided to validate the effectiveness of the proposed AHP-K model. It has been shown that the proposed AHP-K model is better than the AHP model in terms of total utility of projects and investment efficiency.

  • Achievement of objectives of education and training is one of significant factors influencing quality of life. Higher education institutions use different work, teaching methods and tools; however they are inadequate in many cases. Today higher education institutions have problems concerning sustention and rise of certain level of education by giving the job for graduates, using of new technologies that help to present, manage, evaluate and control knowledge. The main objectives of quality management system (QMS) at higher education institutions are as follow: to assure continuous improvement of education quality; to demonstrate performance results and relevant facts to the interested parties (customers of college or university, social partners, administrative institutions) showing the abilities of education institution to prepare high qualification specialists that fully correspond to changing requirements of labour market. The QMS at education institutions should be designed as continuous process, considering that the quality of final product is the result achieved in primary processes. The process shall involve all interested parties. Parameters and indicators of education quality can help to analyze the efficiency and effectiveness of existing QMS. The results of quality audits should be also taken into account when designing and implementing QMS at organization. Literature review showed that for the assurance of education quality three different approaches prevail: total quality management (TQM); requirements of quality awards and assessment models; and QMS corresponding to the requirements of ISO 9001 standard. The case study of QMS design and implementation at Vilnius Law and Business College is presented in the paper. The peculiarities, difficulties and obstacles of QMS implementation in the higher educations institutions are analysed in more detail in this article.

  • This article has tried to analyse the effect of the corporate earning return tax empirically through analysis on the impact of previous internal reservation on the dividends rate of the current year. In addition to this, this article has tried to the effectiveness of government policies with leverage ratio as a moderating variable. Moreover, DRF and GBM model were used to see the effect again. As a result of the actual proof analysis, OCF, ROE, FOR have a significance level of 99% in model1, model2, model3. However, ADV and MSE has appeared not to be meaningful in all models. In the result of DRF and GBM model for convergence was higher than GBM in depth and leaves. However, when it comes to a model explaining capability, GBM high than DRF. The further study will be required to examine the effect of government policy by time series analysis in the period of enforcement of the reflux tax, from 2015 to 2017.

  • It is a very difficult task to establish a collaborative procedure in a new business that requires multilateral collaboration or to revise the regulation by analyzing and proving objectively the problems in the collaborative process conducted already by multilateral collaboration. In this paper, we proposed an optimization model for collaborative process to establish the operation procedure between collaborative parties using PERT/CPM network diagram which allows us to calculate the processing time. In order to verify the effectiveness and usefulness of our model for the collaboration process optimization developed in this study, we applied the developed collaborative procedure to student selection of the work-and-study-in-parallel course associated with a degree executed by Ministry of Employment and Labor. This study can be useful not only for newly establishing or reconfiguring collaborative procedures but also for standardizing the business procedures for building information systems between collaborative organizations.
