Abstract

Exposure of valuable assets of Yemen banking sector to various attacks and threats may violate the privacy, confidentiality, integrity and accessibility (availability) of their data, information or computer systems resulting in financial and valuable loss. Such a violation may adversely affect the continuity of the business and the competitive advantages they seek to achieve. The objective of this paper is to evaluate the current security performance of banking systems in Yemen and to introduce a framework for improving information security management based on the ISO 27002-2013 benchmark and standards. The proposed framework includes important security factors which are people, technology and process. IBM SPSS AMOS is applied for testing framework hypothesis on complex variable relationships and gain new insight. Such framework shows that the process variable has obtained the most direct positive effect on improving information security management system with value (0.990), while the technology variable has obtained the second direct positive effect on improving the information security management system with value (0.930). Finally, the people variable has obtained the least direct positive effect on improving the information security management system with value (0.740). The research methodology includes: data collection, data analysis, reliability testing and computing results. The model validated and compared with other similar models available in the literature and the results were in valid range. Also, the research hypotheses were significant and deferent results of the proposed model were very promising.

Abstract

A new, easy, fast, and cost-effective simultaneous spectrophotometric method for determining the combined concentration of spiramycin and metronidazole in tablet pharmaceutical formulations was developed and proposed. The suggested method was validated using two chemometric techniques, namely partial least square regression (PLS) and principal component regression (PCR). The significance of the proposed method is that pretreatment or separation steps are not required. Various drug concentrations and instrumental spectra of 25 mixed solutions of spiramycin and metronidazole were used for model design and validation. The UV analysis of the prepared mixtures was recorded with respect to a selected solvent blank in the wavelength range of 200–375 nm. The digitized absorbance was sampled at 0.2 nm intervals. The R²values of 1 and 0.9998 assigned for the PLS of spiramycin and metronidazole, and those of 0.9991 and 0.9998 for the PCR of spiramycin and metronidazole, respectively, exhibited greater prediction efficiencies. The results were statistically compared to those of the HPLC reference method. The statistical comparison between the recommended (PLS and PCR) and reference HPLC method did not find any appreciable variations in accuracy or precision. The suggested approach is simple, effective, and trustworthy enough to be employed as an alternative analytical method for quality control of drug analysis in the pharmaceutical industry.
