Mohana Chelvan P and Arumuga Maria Devi T
In recent decades, the dimensionality of the data involved in data mining tasks has increased exponentially. Feature selection is an important dimensionality reduction technique. There will be correlation between privacy preserving data mining and feature selection stability. The essential purpose of privacy preserving data mining is transformation of the original data by some way, and develops corresponding data mining algorithm. The perturbation of dataset may affect the feature selection stability. This paper analysis the problem, and by using an improved algorithm reduces the impact of privacy preserving data mining on selection stability and accuracy.

Influencesthe Type Ofinoculantson the Mechanical Properties and Machinability Ofgray Cast Irongg 25
João Roberto Sartori Moreno and Diego Ruben Martin
The compositions of the inoculants with different elements, as well as inoculant amount, have been shown to play an important role in solidification of cast iron. Three different types of inoculants, INOMAX GB (FeSi-Ba), IMSR 75% (FeSi-Sr) and other IM 22A (FeSi-Ba-Sr), were used in order to obtain different mechanical properties and machining characteristics of a gray cast iron GG-25. The research methodology was to analyze the characteristics of milling of gray cast iron GG-25 according to DIN-1691. However it is expected to obtain results that determine a relationship between the composition of inoculants used with milling material, which suggests the best additive, without changing the microstructures and the mechanical properties of the material. As noted, the material in which the addition of IM 22A was which showed better surface finish than the other two inoculants. Also, the IM 22A inoculant leads to a better machinability of the materials besides lower index of refuse by porosity of 21:43%, against 30.77% for IMSR 75% inoculants and 85.41% for INOMAX GB, mainly due to the type of graphite microstructural. The effects of gross layer removal occur in casting tests turning, with cutting speed of 1200 m/min and ceramic tool (Carbide) without cutting fluid. This influence on the removal of rough machining, generates a substantial yielding loss of the tool, where the flank wear was lower in the cast inoculated with IM 22A.
An Effective Algorithm for Optimizing Random Walk in Vehicle Routing Problems
Enikuomehin A.O, Idowu G.A., Rahman M.A., Jimoh R.G. and Amin A.O.
Traditional product delivery systems have been associated with much delays resulting to reduced marginal profit. This is as a result of poorly formulated Vehicle Routing Plan. The corresponding Vehicle Routing Problem has been an age long problem whose complexity increases as the population set increases. In this paper, the problem is formulated as the conventional optimization problem and solved with a TSPSG algorithm which allows a JAVA coding for optimizing the shortest path and minimizing cost. Numerical tests on a set of benchmark problems indicate that the algorithm out performs existing heuristics algorithms, further results show that the random walk approach is appropriate in solving vehicle routing problems in situations where large set of vehicles are involved.

Mounia TAHIRI, Hassan TABYAOUI, Fatima EL HAMMICHI, Abdelfatah TAHIRI and Hassan EL HADI
This study evaluates the annual soil loss using the Universal Soil Loss Equation Revised (RUSLE) and modified (MUSLE) and Sedimentation module in the sub-basin of oued Sania (Tahaddart basin, northwestern Rif, Morocco). All factors used in RUSLE and MUSLE were calculated using local data. The rainfall erosivity (R factor) was estimated to be 54.75 MJ*mm/ha/h and annual erodibility (K factor) is on average 0.29. The slope in the sub-basin is 16% and the most dominant LS values are below 5. C factor values were calculated from the existing cropping systems in the sub-basin. The results from the crossing of different erosion factors in a GIS show that annual losses to soil varies from one segment to the other surface. The actual erosion by RUSLE method is 47.18 t/ha/year. Total losses by the MUSLE method are 128,240 t/year in average. The average specific degradation is equal to 46.92 t/ha/year. The losses at the outlet are valued at 30.25 t/year. The loss rate due to linear erosion is 44703 t / year. These losses represent 20% of total losses and confirm that the losses on the slopes outweigh the losses due to the water system. The module shows that the sedimentation deposition zones occupy the center of the sub-basin and constitute 48.44% of the total area. These deposits are concentrated at the outlet of sub-basin and contribute to siltation of Ibn Battouta dam.

A Study of AltarDesigns in Seljuk and Ilkhanid Eras
Sara Davoodeh and Kamran Afshar Mohajer
The present study is to investigate the designs of altars (mihrabs) in Seljuk and Ilkhanid eras through a descriptive-analytic method and a library-based research design. The aim is to determine and classify the altars designs in the two eras. So, a comparison of the two is made.
Firstly, the researchers aimed at identifying the structural, aesthetic, special and general characteristics of the altars in two eras. After that, a number of images were gathered. Then, thirty one altar designs were studied through a semi-quantitative research type, because there were some altars without decorated designs, or adequate information was not available.
In the present study, some findings are linked to the visual characteristics by considering the designs. They pointed out that most designs included the fundamental visual elements such as curves, using reflected symmetry, symmetry with vertical axis and making motions through repeated drawings. Also, most drawings are designed Arabesques and rectangular forms. And the Seljuk drawings are adopted from Ilkhanid’s altar drawings.

Bottled water is considered generally of good quality and is not considered to pose any health hazard. However, if it is handled or stored improperly, it may cause a health hazard.
In the center of Morocco, packaged water are form part of consumer products, and there are several brands, most of which are local. Several studies have been conducted on the microbiological quality of water for human consumption. Unfortunately, work on the sanitary quality of drinking water packaged are non-existent.
The aim of this study is to assess the hygienic quality of drinking water packaged and marketed in Central Morocco. In total 50 samples, 10 national brands collected at Fez on different points of the distribution chain (supermarket and grocery stores), have been bacteriological and physicochemical analyzes chemical.
The physicochemical results showed that the values found were good physicochemical and meet drinking water standards Moroccan.
The results of bacteriological analyzes showed that the analyzed waters were free of total and fecal coliforms, intestinal enterococci, Pseudomonas aeruginosa and sulfite-reducing bacteria. Therefore, these results are consistent with national and international standards.
Against by the enumeration of total aerobic mesophilic flora showed that 43% of samples exceeded the limit set by national water standards for viable seeds incubated at 22 ºC and 53 % for viable seeds incubated at 37 °C. These microorganisms may proliferate during the bottling and during storage at ambient temperatures and cause serious health risks for immunocompromised individuals.

Awareness Level of Patients’ Rights among Patients in Chennai City
S. Vasantha and Dhyana Sharon Ross
Patients’ rights are a fundamental human right, a quality assurance measure that protects patients against abuse and discrimination and promotes ethical practices. The assurance given to the patients that their rights are protected needs more, than educating policy makers and healthcare providers; this requires educating patients or their relatives about what they should expect from their healthcare providers, about the kind of treatment they are receiving and treatment’s possible side effects. The effectiveness of patient’s rights depends on the knowledge of the patient and their relatives along with the awareness of the ethical, social and legal issues surrounding them. It is also the duty of the patient or his/her relatives to get information about the treatment given. Successive cooperation of both, patient and healthcare providers is required to achieve fruitful outcome in patient’s treatment and hospital growth. The aim and purpose of this research was to study the way in which patients’ rights. The purpose of the study is to analyze the effective implementation and awareness on patients’ rights and education among patients. This study involves collection of information from patients of various hospitals from Chennai, Tamil Nadu, India. Data were collected using questionnaire and structured interview with 150 patients/relatives
These patients ignored the fact that special regulation are in existence regarding their right. Patient/ Relative considered their right to information was being respected, albeit to different degrees.

The Mechanism of Credit Cyclicity: Institutional Channel of Credit Risk Transmission
Dmitry Vladimirovich Burakov
In this study, we put forward a hypothesis about the impact of institutional quality of the national market on the specifics of credit dynamics over the credit cycle. Given that the core of the credit cycle is the motion of credit risk, we aim to assess the impact of the institutional infrastructure of the national economy on 1) the level of credit risk accepted by commercial banks and 2) on the features of its movement at the different phases of the credit cycle. Proceeding from the results of the statistical cross-country analysis, we conclude that the institutional channel of credit risk transmission (including both the level of protection of creditors’ rights and the overall quality of market institutions) has a significant impact on the specifics of the credit risk dynamics. On the one hand, weak enforcement of creditors’ rights reduces the willingness to meet the demand for credit (including credit risk acceptance rate) and generates a high rate of credit rationing that, in general, negatively affects economic development. On the other hand, in economy of rent-seeking, low quality institutions of rights and commitments control while reducing the availability of credit increases accepted credit risks due to the wide spread affiliation in lending through bribery schemes and interpersonal affiliation. The consequence of this channel functioning becomes the change in the amplitude of the credit cycle and its magnitude. Managing the institutional channel of credit risk transfer properly is seemed to be of the main importance in achieving the goal of credit market’s development stability.

Premature mortality due to poisoning remains a serious problem in many countries of the world. The present work aims to study the premature mortality due to poisoning in the Souss-Massa-Draa Morocco to determine characteristics related to deaths that may influence the prognosis of patients. This is a retrospective study of all cases of poisoning listed between 1981 and 2012 by the Anti Poison Centre and Pharmacovigilance Morocco in the Souss-Massa-Draa. We focused more specifically to a premature death before age 65. During this period, the number of cases of poisoning patients whose age was lower at age 65 was 6037 (195 deaths). The mortality rate was calculated as 6.69 per 100 000 inhabitants, thus saving 8349 years lost among addicts death. Females are more affected than males with 106 deaths (4165 years lost). PYLL highest has been observed in adults and adolescents with 3730 and 1753 lost years respectively. 1962 years lost were observed in suicides industrial products, 1622 years lost in poisoned by ophidian envenomation and in most cases are women.

Loan Acquisition in Microfinance Poverty Alleviation Programme in Ogun State Nigeria and Quality of Life of Beneficiaries
Adeyinka A. Ilori and John A. Enahoro
Nigeria is believed to host the largest population of the poor in the West Africa Sub region. The Federal Government of Nigeria, States and Local Governments have developed poverty eradication policies but not much has been achieved. Among poverty alleviation programmes is the establishment of microfinance institutions expected to provide credits for small and medium scale enterprises which could not fulfil the collateral and other requirements of commercial banks for facilities. Literacy level and unstructured financial services have combined to motivate the poor to seek help from money lenders who charge exorbitant fees. The cycle of debt entrapment adds to afflicting the poor. Against this background, it is imperative to determine the relationship between loan acquisition and business growth of beneficiaries of microfinance poverty alleviation programmes. This study examined quality of life of loan and credit beneficiaries in the Ogun State of Nigeria. Methodology adopted survey questionnaires and personal interview instrument which benefitted from extant literature dealing with poverty alleviation and micro financing. Specifically, the roles of microfinance in the alleviation of poverty were developed from the literature using the works of Irobi (2008), Sekhampu (2012) and Fasoranti (2010). The study adopted the multi-stage sampling method and a probability sample of the beneficiaries using stratified random sampling (Ekundayo,2009). The paper concluded that the determinants of poverty alleviation such as loan acquisition and active participation of loan benefiaries concerned are crucial to the improvement and measurement of standard of living and poverty level of beneficiaries of micro finance banks in Nigeria.
