Abstract: Over the years, the database administrator’s job has continued to grow more challenging. DBAs have always had complex and stressful jobs, but recently they have needed to confront the following trends: New Platforms - Most DBAs manage at least two different database platforms and many are responsible for three or more. This challenge is made even more complicated by a mix of operating systems. Added Complexity - Database giants say their database engines are “self-managed”. While it is true that management improvements continue to be made, database software is escalating in complexity and there is much to learn, understand, and master with each new database release. More Data - The need for more data and more space relentlessly increases and databases continue to expand, both in size and number, adding more burdens for the DBA. This paper will outline techniques used to streamline and automate the management of these critical areas so as to deliver high database performance and availability.

Abstract: ‘Error analysis’ is the field that deals with the actual errors and tries to describe them in linguistic terms and explain some of the probable sources of errors which provide an understanding of the underlying process of second language acquisition. The purpose of this current study was to assess, describe and analyze the errors committed by Saudi EFL students of Jazan University. The investigator has followed the methodology of error analysis suggested by Corder (1973). It involved recognition of errors, description of errors and explanation of errors in terms of their sources and evaluation of errors. For this purpose, a test in writing has been administered on the sample of the study. The participants comprised of 100 undergraduate students of Department of English, Girls’ Samtah campus, Jazan University. The data was analyzed in percentages on the frequency of errors. The students have committed interlingual and intralingual errors while writing in English. The findings from this study indicated that the participants do not have the desired knowledge in morphology and syntax of English language to perform well in writing tasks. Findings of error analysis function as facilitator in their language teaching in many ways only if the teacher is aware of them and able to make use of them in the teaching process appropriately. A structured interview was conducted for 10 English teachers to know the reasons behind students’ problems and find out solutions to overcome problems while writing in English. English language teachers should take the responsibility to motivate the students in a way to create interest towards learning English and be a stress free environment. They are requested to take steps to diagnose the different kinds of errors committed by students so as to improve their proficiency in English. Orientation programs and refresher courses should be conducted to all the English language teachers in the university.

Abstract: The present investigation revealed Botryodiplodia theobromae, Aspergillus niger, Aspergillus flavus and Aspergillus glaucus as causes of post­-harvest rot disease of yam tubers on the bases of pathogenicity test. Hot extracts of 10g, 30g and 50g /100ml of Chromolaena odorata inhibited Aspergillus flavus to 92.19%, 92.19% and 97.77% respectively, while 20g and 40g/100ml inhibited Aspergillus glaucus to 95.56% and 92.22% respectively. 10g, 40g and 50g/100ml of cold extract of C. odorata inhibited Aspergillus niger to 98.08%, 96.69% and 96.92% while 20g/100ml concentration inhibited B. theobromae to 96.86% and the least inhibited being Aspergillus flavus (93.31%). 30g and 40g/100ml concentration of C. odorata inhibited Aspergillus flavus to 89.97% and 98.89% respectively, while Aspergillus niger (96.16%) was least inhibited. Cold aqueous extract of C. odorata at 50g/100ml inhibited B theobromae by 95.24%. Both hot and cold extracts of C. odorata were found to be very potent against yam tuber rot pathogens. These serve as preferred alternatives to chemicals which usually have negative effects on the environment.

Abstract: The base of available information technology resources is increasing with dramatic speed. Much has been learned about connecting various forms of technology into systems, so that the ability to link systems is growing. Most distance learning systems are hybrids, combining several technologies, such as satellite, ITFS, microwave, cable, fiber optic, and computer connections. Technology transports information, not people. Distances between teachers and students are bridged with an array of familiar technology as well as new information age equipment. What sets today's distance education efforts apart from previous efforts is the possibility of an interactive capacity that provides learner and teacher with needed feedback, including the opportunity to dialogue, clarify, or assess. Advances in digital compression technology may greatly expand the number of channels that can be sent over any transmission medium, doubling or even tripling channel capacity. Technologies for learning at a distance are also enlarging our definition of how students learn, where they learn, and who teaches them. No one technology is best for all situations and applications.

Abstract: Chaos theory has been applied in manufacturing systems in the recent years. An investigation has been done on chaotic behavior of assembling system. The assembly line is flexible which can accommodate variety of product types. An algorithm is proposed and a model developed is implemented on real life data in which analysis is performed to obtain time persistent data. The behavior of the system is observed for work in process as this is sensitive in the process. It has been found that the flexible assembly line exhibits chaotic behavior by showing that the computed average Lyapunov exponent is positive.

Abstract: The purpose of this study was comparison between two face-to-face and virtual teaching methods and combination of these two methods in learning science. Using cluster sampling, three classes with 20 students in each class from the students of first grade of Tehran city's junior high schools was chosen, and for 45 days, each of the experimental variables ran on them. The experimental pre-test - post-test method was used to collect data. Data analysis was performed using T test and ANOVA. Results showed that there is no significant difference between the virtual and face-to-face methods (t=0.41) and variance analysis showed there is a difference between the three educational methods, face-to-face, virtual and the mixture (F=7.008). There are also differences in the survival rate of learning in three ways (F=6.78). HSD test results showed that students had a better performance in learning science with the combinational method rather than two other methods and the survival rate of the learned contents is better too.

Abstract: Small and medium enterprises (SMEs) with their crucial role in generating employment and supporting trade are encountering numerous challenges. Meanwhile, towards to stay alive in a competitive edge in today’s dynamic business environment, SMEs are improving their usage of information systems (IS) and increasingly implementing of enterprise resource planning (ERP) systems. However, successful implementation and utilization of ERP systems requires adequate attention to a proper and comprehensive implementation framework and considering of significant critical success factors (CSFs) in implementation phases. Expert panel with ten experts and interview instrument was conducted in this research. This study aims to contribute three major goals: to find the required characteristics of SMEs' framework and then propose a conceptual framework and seek the relevance of critical success factors (CSFs) along the four phases of proposed framework for implementation of ERP systems in SMEs of developing countries. These findings aim to saturate the proposed frameworks that can help SMEs of developing countries towards improving the ERP implementation success rate. The case study in Iranian SMEs was used to validation of the final proposed framework.

Abstract: Distance education can be used for some aspects of most disciplines. For example, several institutions of higher education already have developed certificate programs, undergraduate programs, and graduate programs in health and physical education that are delivered using distance education methods. Eastern Oregon University, Emporia State University, Kutztown University, LaSalle University, the Medical College of Wisconsin, University of Wisconsin at Stevens Point, and Virginia Tech are among institutions integrating distance technology into their physical education programsDistance education is education designed for learners who live at a distance from the teaching institution or education provider. It is the enrollment and study with an educational institution that provides organized, formal learning opportunities for students. Presented in a sequential and logical order, the instruction is offered wholly or primarily by distance study, through virtually any media.
