A Study on Legal Challenges of Issuance of Smart Cards and Electronic Archive of Identity Documents
Rozita Karimpour and Maryam Karimpour
Among advantages of electronic commerce, contribution to the trade globalization, removal of time and place restrictions, acceleration of interchange process, rapid and easy access to information, and optimal allocation of economic resources can be mentioned. Thus for proper development of electronic commerce, some measures must be undertaken for creating proper telecommunication infrastructures, security in data interchange, legislation of proper legal rules, creating cultural infrastructures, making people and economic enterprises familiar with advantages of electronic commerce and electronic payment, creating broadband, internet with high speed and reducing its costs and make it available for the public. Increasing development of information and communications technology has increased the citizens' expectations of the government in providing services. By implementing e- government, the governments may provide the services required by people more efficiently and quicker. In implementation of e- government, general services are divided into several groups and in each group, several services are defined. Among them, some services have priority over the others, and with regard to the restricted financial resources of the governments, it is obvious that the major part of financial resources must be allocated to the services with higher priorities. Effective experiences of the developed and developing countries reveal different classifications of services and policies. The present paper studies the legal challenges pertaining to the issuance of smart cards and electronic archive of identity documents.
Keywords: Legal challenges, issuance, smart card, electronic archive, identity documents.

Kamal A.S Al-Banawi
In this paper we study generating polytopes of transnormal tori in . A transnormal torus is a special case of transnormal partial tubes, which are transnormal spherical bundles over some transnormal manifolds, called bases. We show that a generating polytope of a transnormal torus in is a rectangle with one length equal to the width of the base, and the other length is the diameter of its sphere bundle. Examples of such generating polytopes are introduced.

Parasitic Contamination of Fodder Consumed by the Grasscutter (Thryonomys Swinderianus) Breeding in Urban and Suburban Areas of Abidjan (Cote d'Ivoire)
Emanfo Alex Stéphane Affian, Komoin Clarisse, Karamako Yahaya and Fantodji Agathe
Fodder collected in urban and suburban areas is increasingly used in domestic herbivores feeding, in general, and the grasscutter particularly. This fodder, often in contact with human and animal waste, can be contaminated by gastrointestinal parasites of this environment.
The general objective of this study was to evaluate some health risks related consumption of the meat of Grasscutter fed with urban and suburban fodder. The specific objectives were:
First, identify the parasitic genera and species found on two forage species (Panicum maximum and Pueraria phaseoloides) frequently used by breeders to feed their animals;
- Then, determine the influence of the cutting height on the presence of parasites;
- Finally, determine the influence of the state of fodder (fresh or dried) in the presence of parasites.
To achieve this goal, forage samples were taken from two sites (modern forage site of Nangui Abrogoua University (UNA) and the natural forage site of Riviera M'Badon (Eden) in Côte d'Ivoire). They were analyzed by the method of direct observation in the Central Veterinary Laboratory of Bingerville (LCVB).
This study has identified the presence of four species and one genus of parasite on the site of the UNA: Dictyocaulus viviparus
(prevalence 66.45 %), Strongyloides papillosus
(12.47 %), Dictyocaulus filaria
(10.90 %), Delafongia vulgaris
(2.34 %) and a mite of the genus Sarcoptes
(7.79 %). Forage taken from the site of Eden has showed 5 genera and one species of parasite: Trichomonas spp
(91.92 %), Balantidium
spp (4.78 %), Haemonchus
spp (1.69 %), Sarcoptes
spp (0.22 %), Trichinella
spp (0.71 %) and Dictyocaulus viviparus
The results obtained show that the fodder cut at 8cm of ground and dried is free from larva of parasite. While, the fresh fodder cut to the root presents a very high parasitic load.

Security Measure for Black Hole Attack
K.R. Viswa Jhananie and C. Chandrasekar
Black hole attack is one of the security attacks that occur in Mobile Ad-hoc Networks(MANETs).In this paper, we present a solution that prevents black hole attack. Two different protocols are used for nodes that travel from source to destination, so that when data gets attacked in one route, it can be saved in the other route . We simulated black hole attack using network simulator(ns-2) and throughput is calculated. Ad-hoc On Demand Distance Vector(AODV) and Dynamic Source Routing(DSR) are used for simulation. City Section Mobility Model is chosen for implementing our idea.
Keywords: Ad-hoc networks, black hole attack, malicious node, protocols.

Hadi Tehrani, Maryam Saber, Davood Shojaee Zadeh, Mostafa Shokoohi and Fereshteh Majlesi
Although the error in health care has received attention recently, patient safety culture in health centers has been relatively neglected. This study has been conducted with the aim of evaluating the culture of health care providers towards patient’s safety among employees of teaching hospitals.
The study sample consisted of 440 employees of educational and treatment centers affiliated to Kerman University of Medical Science. A standard questionnaire named “hospitals evaluation in terms of patient safety culture” was used to evaluate the patient safety.
The maximum and minimum score belonged to the area of “management support from patient safety” and “non-punitive response in cases of error” with mean positive response of 72.20% and 56.3%, respectively. Result shows that participants aged >35 years had better overall understanding towards the patient safety than those less than 35years. In total, there was not statistically significant difference between men and women in terms of patient safety.
Patient safety culture still has many areas for improvement that need continuous evaluation and monitoring to attain a safe environment both for patients and health-care providers. Improvement in patient safety needs changing in system such as holding comprehensive training programs about patient safety culture for employees.
Keywords: Patient safety culture, treatment services provider, hospitals.
Iranian Drama; A Comparative Study on Dramatic Ending Strategies
Majid Kianian and Mohammad Jafar Yousefian Kenari
In this article, attempt has been done to focus on structural effects of some of the most important Iranian dramas in 1380s (2000s) in order to prepare a comparative study for the common patterns of their ending. Here is an effort to get a new concept of narrative feature of Iranian contemporary dramas in addition to, even better, understand how to organize the information on the final screen of these dramatic artworks. However it would be possible by choosing a conceptual framework derived from the contemporary theater critics` ideas such as Martin Esslin and Manfred Pfister. This paper, based on the most significant forms of ending related to the works of this decade, pays attention to measuring the defined dramatic values and their impact on the overall structure of the narrative in study samples. The research uses a descriptive-analytical method and intends to identify the common patterns for ending of plays relevant to this decade. The findings show that despite the thematic and structural variation, the plays usually tends to a kind of empiricism in using the patterns for semi-finished, unfinished and open ending. Reflect of this major trend can be found in recent Iranian playwright’s` narrative styles and innovation in their styles of writing. The variety of endpoints and the strategies for ending in Iranian dramatic works of relating to past decade are presented in tables and graphs.

Production Inventory Model for Three Levels of Production and Demand with Integrates Cost Reduction Delivery Policy
C. K. Sivashankari and S. Panayappan
This paper integrates a cost reduction delivery policy into an production inventory model with defective items in which three different rates of production and demand are considered and it is possible that production started at one rate and after some time it may be switched over another two rates such a situation is desirable in the sense that by starting at a low rate of production, a large quantum stock of manufacturing items at the initial stage is avoided, with the purpose of reducing holding cost. A suitable mathematical model is developed and the optimal production lot size which minimizes the total cost is derived. The global optimal solution is derived and an illustrative example is provided and numerically verified. The validation of result in this model was coded in Microsoft Visual Basic 6.0
Keywords: Production Inventory, defective items, cycle time, demand, production, multi-delivery policy and optimality.
A Novel Circular Shaped Microstrip Patch Antenna in the K-Band
Youssef Rhazi, Seddik Bri, Rajaa Touahani and Ahmed Mamouni
In this paper, a new step by step method is introduced to design a novel circular shaped microstrip patch antenna. The calculations are based on transmission line model. The feeding uses a uniplanar corner-fed patch antenna presented with single-point microstrip.
This work presents a new model for design of circular microstrip antenna (MSA). In this model, a closed form expression is used for accurate determination of the resonant frequency of circular microstrip patch antenna. The calculated resonant frequency results are in good agreement with the simulated results reported elsewhere.
We present the simulations results of two types of circular patch antenna in K-band. The conception of this patch antenna is realized by software HFSS "Ansoft-High Frequency Structure Simulator". Details of the design and the simulation results are presented. Patch radius decreases as the resonant frequency increases (R=3.06 mm at 18.31 GHz and R=2.51 mm at 19.35 GHz). The results obtained in this design compare favorably with results obtained from manual computation of the same parameters and these agree with other designs such as the rectangular patch.
The deduction made from the results showed that modified CPW antenna is suitable when smaller antenna size and low power handling capability is a priori.
