Melba Sheila DíSouza, Jolly Jose RN, Sharifa Saif Al Jabri

Aim. This paper is a study regarding perceptions of teaching among Registered Nurse Preceptorsí (RNP) for baccalaureate (BSN) nursing students in a public hospital in Oman. Background.In the final year of the BSN program, students begin thetransition in roles from student to nurse professional using the preceptor model. Method.A cross-sectional descriptive design was used to collect data using a self-administered questionnaireamong RNPs (n = 30) for BSN students in 2009 in a public hospital. Data were analysed with descriptive statistics. Findings.RNPs perceived difficulty in monitoring professional and critical thinking behaviours, were unable to provide accurate clinical evaluations and lacked time to discuss and demonstrate nursing care. They had increased patient assignments, changes in their duty roster and were unable to provide feedback of the student learning objectives. RNPs who precepted unsafe students reported that students lacked responsibility and accountability, lacked adequate knowledge, competencies and safe practice and failed to abide to the standards of nursing care. Conclusion. There is a need to support the needs of the preceptor, facilitate teaching-learning process and effective strategies to precept unsafe students.Clinical support must be provided to plan nursesí clinical work so that allocatedtime for precepting can be facilitated. Relevance to clinical practice. Preceptors play an important role with final year student nurses prior to graduation. There is a need to ensurethat nurses are provided the necessary support, recognition and resources for effective preceptorship.

A Review on Framework and Quality of Service Based Web Services Discovery
Mustafa Almahdi Algaet, Zul Azri Bin Muhamad Noh, Abdul Samad Shibghatullah and Ali Ahmad Milad

Selection of Web services (WSs) is one of the most important steps in the application of different types of WSs such as WS composition systems and the Universal Description, Discovery, and Integration (UDDI) registries. The more available these WSs on the Internet are, the wider the number of these services whose functions match the various service requests is. Selecting WSs with higher quality largely depends on the quality of service (QoS) since it plays a significant role in selecting such services. In achieving this selection of the best WSs, the potential WSs are ranked according to the userís necessities on service quality. In many cases, the value of QoS ontology is realized by its support for nonfunctional features of WSs. This ontology is also capable of providing solutions to the interoperability of QoS description. Moreover, based on the QoS ontology, it becomes more possible to develop a framework of semantic WS discovery. The framework enhances the automatic discovery of WSs and can improve the usersí efficiency in finding the best web services. Thus, Web Services are software functionalities publish and accessible through the Internet. Different protocols and web mechanism have been defined to access these Services.

A Multi-Objective Model for Time-Cost-Quality Trade-Off (TCQT) Considering the Effectof the Reverse Time

Farzad Movahedi-Sobhani, ShahabHassanpour and NedaAshour

Time, cost, and quality are crucial purposes in a project. They are independent and conflict together. Therefore shortening the project completion time by speeding up one or more of the project activities affects direct costs and the quality of the project. In real projects, time, cost, and quality are estimated by experts and a project manager, so they are imprecise. Therefore time, cost, and quality are expressed by fuzzy triangular numbers. In this paper we propose a multi-objective model for time-cost-quality tradeoff. We suggest some new activities, if they become necessary, to improve quality after crashing time. Some of these activities might be performed in normal time. In fact, the effect of reverse time is considered. We consider the Average High Ranking (AHR) method for use in defuzzifying triangular numbers. Also we apply LP-metric method to solve a multi-objective model. This model can be used by project managers for project scheduling.

Sajjad Forghani, Bahram Karimi and Elahe Saeedi

In according to importance of pressure control in drilling systems, in this paper, an adaptive neural network controller is proposed for drilling system. This controller is designed to stabilize the choke pressure, pump pressure and volume flows through drilling bit. The stability of the closed loop system is guaranteed by introducing a robust adaptive bound based on Lyapunov stability analysis. A radial-basis function neural network and input-state linearization are used in the paper. Finally, we performed some simulation studies; the simulation results verify the merits of the proposed controller.

Wireless Ad Hoc Networks Routing Issues

Razieh Hajihashemi, Mohammad Reza Soltanaghaei and Amirabbas Mahdavi Shahri

Ad hoc network is defined as an ďinfrastructure-lessĒ network. It means a network without the ordinary routing like fixed routers and access points. Regularly, the ad hoc nodes are not fixed and the communication medium is wireless. Each ad hoc node may be capable of acting as a router. Such ad hoc networks may be seen in personal area networking, meeting rooms and conferences, etc. Some aspects of ad hoc networks have interesting security problems. Routing is one such aspect. Several routing protocols for ad hoc networks have been developed specially in the MANET working group of the Internet Engineering Task Force (IETF). The existing ad hoc routing protocols do not accommodate any security and are highly vulnerable to attacks. We discuss threats and attacks against ad hoc routing under several areas of application. We also look at some suggested solutions that could be used when secure protocols are designed. The current protocols should not be used in hostile environments unless the applications are especially designed to operate under insecure routing or until protocols with enhanced security are introduced.

M.H. Azadi, A. Khakzad, M. Karimi and M.R. Vaseghi

The study area as a part of Sanandaj-Sirjan Zone (SSZ) is located in about 190 km NE of Neyriz, Fars province, SW Iran. Igneous activity resulted from subduction of Neo-Tethys beneath Iran microplate during Mesozoic and Cenozoic produced several intrusive and extrusive rocks throughout Sanandaj-Sirjan Zone that convoluted intrusive complex in NE of the study area is one of them. The Kore Sefid intrusive rocks with approximate age of 181 milion years emplaced into SSZ. In this study, we have focused on petrography, genetic aspect and tectonomagmatic problems of the Kore Sefid intrusion. First of all, field studies and sampling in the area was carried out for performance of this research. Major elements concentrations were analysed by X-Ray Fluorescence method (XRF). The chemical analysis of samples(for analysis of rare elements and REEs) were investigated through Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) methods. The Kore Sefid intrusive rocks composed of granite, granodiorite, tonalite, aplite and low pegmatite. The magmatic positions of Kore Sefid rocks set in calc- alkaline site (medium K affinity), based on their chemical compositions. Kore Sefid granitoid due to A/CNK vs. A/NK (Alumin Saturation Index) characterized with peraliminous nature.These granitoids are compositionally similar to normal S-type granitoid rocks. The tectonomagmatic diagrams used by rare-elements characterized the Kore-- Sefid rocks in a continental arc-setting (CAG). Tectonic setting discrimination diagrams show the position of the volcanic arc granitoids (VAG) for them. The studied granitoidic rocks have high Light Rare Earth Elements (LREEs) (La, Ce and Nd) relative to Heavy Rare Earth Elements (HREEs) and they indicate relatively enrichment to Large Ion Lithophile Elements (LILEs) (Rb, Th) and depletion in Eu ?Sr, Ba and High Field Strength Elements (HFSEs) (Ti?-Y?Yb?Nb?Zr?Hf).The geochemical characters indicate that the sources of these granitoidic rocks would have continental crust affinity which sedimentary rocks in composition. The geochemical characteristics explained the arc related subduction environment.
