Title: Redox titration of iron using methylene blue as indicator and its application in ore analysis
Authors: Erik Prasetyo, Fika R. Mufakhir
Paper ID: ATBAS-60118057
Abstract: Dichromatometry titration procedure to determine iron content using methylene blue as redox indicator was investigated. The effectiveness of this procedure was then compared with standard dichromatometry titration in which barium diphenylamine sulfonate was applied as indicators. The result showed that the titration procedure using methylene blue could be served as alternative procedure in terms of reproducibility and accuracy. This procedure even owned advantage compared to existing standard methods, since it did not incorporate Zimmermann Reinhardt reagent as in standard permanganometry and phosphoric acid as in standard dichromatometry titration in iron determination.

Title: Mathematical Modeling of HIV/AIDS Transmission among Injecting Drug Users with Methadone Therapy
Authors: N. Nuraini, R. Irawan, Zulkifli, & E. Soewono
Paper ID: ATBAS-30120054
Abstract: This paper discusses an improvement model for the spread of HIV/AIDS among a population of injecting drug users. We begin with a detailed description of Kaplan's model and another realistic extension performed by Greenhalgh and Hay. In the first model, methadone therapy is added for modification. The therapy itself is believed to be safe and effective in controlling the spread of HIV/AIDS. Then equilibrium and stability analysis are performed on these models. These results are confirmed and explored further by simulations.

Authors: Alsalloum, Othman Ibrahim
Paper ID: ATBAS-50123056
Abstract: This research deals, descriptively and analytically, with the tendencies of the staff of the General Organization for Social Insurance in Riyadh towards implementing a system of electronic transactions by recognizing the staff’s tendencies in the following fields: administrative aspects, security and information technology, processing and retrieving information and the level of staff performance in the organization. The research adopted a descriptive analytical approach as well as a questionnaire in collecting data and information. The research sample included 65 employees out of 341 chosen randomly with a stable percentage of 20%. The research also used percentages, averages and standard deviation to know the extent of benefit from the electronic transaction program known as SIMIS. The research found out a set of results most important of which is that the General Organization for social insurance, with its branch in Riyadh, has started since 2002to offer service for participants through Social Insurance Management Information System (SIMIS). The averages of the statements of administrative aspects ranged from 2.627 to 3.932, and there was an increasing demand for technology products with an average of 3.554 upon applying electronic transactions. And the averages of the statements in the field of processing and retrieving information ranged from 3.220 to 4.458. The information provided by the system of electronic transactions for the staff is sound and error free with an average of 3.220. The research recommended the necessity for diversity in using modern technology in information management system, raising the level of security and confidentiality of data and information conducted among staff and administrations and rehabilitation of staff through interior and foreign scholarships

Title: A Study on the Students' Response to the Implementation of Virtual Schooling in Public Schools, Kingdom of Saudi Arabia
Authors: Alsalloum, Othman Ibrahim
Paper ID: ATBAS-90122054
Abstract: The aim of this study is to explore the response of the students to the implementation of virtual schooling programs in the Saudi public schools, so much as to realize the extent to which the implementation of virtual schooling is needed. The study also aims to define the concept of the virtual school, its elements, types, environments and requirements. Moreover, the study embarks upon other studies on the same subject. The study data were collected through distributing questionnaires. They have been designed in a way that is easily understandable and comprehensive. The program SPSS was used in analyzing the questionnaire and drawing conclusions. One of the main findings of the study is that the majority of students believe that virtual schooling is an urgent need imposed by the technical developments of modern age. They also believe that it provides faster access to information. According to them, the main obstacle to the implementation of virtual schooling was the lack of internet at school. Among the most important recommendations of this research are preparing the appropriate infrastructure for schools, preparing students for interacting with e-schools, educating parents and increasing the financial allocations for the schools that implement virtual schooling programs.

Title: The Impact of Applying E-Government to Improve the Performance of the Ministry of Education in Saudi Arabia
Authors: Alsalloum, Othman Ibrahim
Paper ID: ATBAS-90124050
Abstract: The purpose of this study is to identify the trends of directors in the Ministry of Education towards the adoption of e-government as well as the effect of e-government application on job performance and to discover the problems that could hamper the process of applying it and the availability of the necessary requirements to implement e-government to the directors in the Ministry of Education. The study population is comprised of (115) directors in various administrative levels in the Ministry of Education in Riyadh. In order to achieve the purposes of study, the researcher designed a questionnaire consisting of 13 paragraphs on the Likert scale (Strongly Agree = 5, agree = 4, neutral = 3, disagree = 2, strongly disagree = 1). In this study, the researcher followed an analytical and descriptive approach that suits the nature of the research. Moreover, the stability of the questionnaire was verified by making a re-test with a one-week span. From the analysis of responses of directors we discovered that e-government in the current methodology has not yet reached a compromise with a full-system and still lacking in significant improvement in many respects, also that e-government does not only convert the service system and work to an electronic system, but it’s a complex and interrelated system and requires in-depth studies to all elements before completing the automation of all services. The shift from traditional government to e-government with the invasion of new informational world represents a significant challenge to the government.

Title: A Biometrics Approach to Population Census and National Identification in Nigeria: A Prerequisite for Planning and Development
Authors: Anthony T. Eniayejuni, Mary Agoyi
Paper ID: ATBAS-80121059
Abstract: Despite the series of population census that has been carried out over the years, the question of how to implement population census and the real population of Nigeria still remains unanswered. This paper analyses the importance of statistical knowledge of Nigeria’s population, in terms of planning and development. In order to have an accurate and trustworthy data of Nigeria citizens, a biometric system for data collection is proposed as well as a centralised database for storing these data. Although biometric system is not a new technology but it is new in this part of the world as it has not been in use in Nigeria. This technology will give Nigerian government a statistical knowledge of its population data which is of critical reference to ensure equity and distribution of governmental resources. It will also serve as a precursor for effective planning, development and service delivery to its citizens.
