In this paper, a three layer Small single feed multiband microstrip antenna loaded with slit and two perpendicular shorting posts, is presented. Wide band frequency of operation demonstrated by single geometry, for broadening the bandwidth gap-coupled multi-resonator loaded on the patch, the simulation of proposed design antenna has done by MOM IE3DTM Simulator. The geometry of a single probe fed rectangular microstrip antenna has textured by slit loading and two orthogonal shorting pin on the top layer patch. We have also textured the size of the antenna. This proposed antenna is used for GSM, satellite and wireless communication in, L Band. Achieved 63% reduction of geometrical area of the antenna for L –Band, achieved 57% -10dB impedance bandwidth of L Band.

Metal- ligand complexation in solutions was studied in water-methanol media by pH-metric titration with the standard glass electrode at ionic strength of 0.1M KNO_3. The titrations were carried out at various temperatures 35^oC, 45^oC, and 55^oC and the pKa values (stability constants) were determined. Copper (II) with benzimidazole gave pKa’s of 2.86, 2.52, and 2.46; Stability constant (logK) 338.80, 331.13 and 288.40 while Nickel (II) benzimidazole gave pKa’s 2.51, 2.60 and 2.38 and Stability constant (logK) 323.59, 398.11 and 239.85 respectively.  It was revealed that the stability constants of the metal complexes decreased as the temperature increases. Formation constants obtained for these complexes showed that metal- ligand ratio were in the range of 1:1 and 1:2. The thermodynamic parameters were also determined at the working temperatures and the results obtained showed negative ?H and Gibb’s free energy (?G) indicating exothermic and spontaneous reactions.

Intelligent driver systems and vehicle connectivity have made systems like RFID based traffic control systems, automatic collision notification obsolete. In addition to collision notification, cooperative collision avoidance and other applications using connectivity between the vehicle and signalized intersections have emerged. Applications avoiding collisions, enhancing fuel economy and reducing greenhouse gases (GHG) are the subject of this paper. The interaction between vehicle and traffic management systems could revolutionize the traffic problems of a crowded metropolitan city. This paper will employ connectivity as an enabling technology for sustaining the vision of smart and green transportation systems.

Medical tourism is developing a new dimension in Malaysian healthcare system and its diversifying the national economy. In order to be competitive in this emerging industry, Malaysia needs to identify and implement competitive strategies based on the needs of medical tourists globally and the availability of its resources in the country. Literature review shows the study on medical tourism is focusing on wide variety of issues ranging from cost, promotion, barriers and cultural aspects. This conceptual paper would like to propose the extension of Porter model and Peng Y model of internationalization in medical tourism research. Porter model usually used in manufacturing and service oriented research. Whereas Peng Y model usually used in the international business studies. As medical tourism is moving forward to be a competitive industry and it is happening globally, it is wise to extend or associate those two models in the medical tourism research. Therefore, this paper is focused on competitive strategies, institutional based strategies, industry based strategies and resource based strategies that the health care centers need to adopt based on the both models. A theoretical framework is proposed to research emphasizing on the above four strategies in medical tourism.

One of the framework which could be utilized in management development is management competencies. This approach have focused the attention of researchers in recognition to key competencies for managers which have believed that the deep study of managerial competencies opens the road for development & enrichment of organization’ management. From mid-1980, the managerial competency development caught the interest of organization, the reason for such desire was the belief that managerial competency development have many benefits for organizations and this belief still stands (Ghaffarian, 2000:71). Pedagogy & selection of mangers and leaders is the most problematic issue for cotemporary progressive organizations. What kind of qualifications must a manager have(Abraham&Karness, 2001:843( for successful performance of his duties and achieving organizational’ goals(even beyond that)? A definition of qualification is as such: “Qualifications are managerial features which lead to appearance of skills & capabilities that would cause effective performance in any occupational domain; Also, incarnates the capacity for transfer of skills & capabilities from one domain to another”. In this definition, the superior performance means that the individual with specific qualifications is in upper level(Chen, 2004: 105). Competency has various meanings and still has remained as one of the most important term in organizational literature(Robatam , 1999). Based of definition of Boyatzis (1982:23), competency is a constituent in which emphasizes on personal attributes of individuals for achieving his effective job performance. Therefore managerial competencies consist qualities and capabilities of managers which leads to effectiveness of managers in work environment( Voudal 1998:4).

Our information-gathering behavior has always been to find out what other people think. Opinion-rich resources such as online review sites and personal blogs are growing rapidly which provide new opportunities and challenges, as people can actively use information technologies to seek out and understand the opinions of others. People share their experiences on-line, express their opinions, frustrations about anything. The huge amount of available data creates opportunities for automatic mining and analysis. It can be considered as a classification task: their feelings can be positive, negative or neutral. People don’t directly express sentiment, They can also use a diverse range of other methods to express their emotions. Authors may mix objective and subjective information about a topic, or write down psots about other topics than the one we are investigating. And also there is a lot of noise in the data gathered from the Web pages. Due to this the task of automatic recognition of the sentiment in on-line text becomes more difficult. The content we are interested in this paper is, what is sentiment analysis, how the sentiment analysis was useful for a bank, how can it be applied in market intelligence and what are the challenges that could be faced in Indian scenario.

The purpose of this paper is to present some instructional ideas for second language (L2) listening comprehension and their alignment with listening assessment. Among the suggestions are using spoken texts as instructional input, introducing the micro- and macro markers and providing students with authentic texts. In addition, the paper also highlights the importance of awareness-raising on the differences between spoken and written language among L2 learners. To expand the extant of the scope of possible instructional ideas for L2 listening, the discussion on pre-teaching of listening input and its connection to learners’ schemata is also included. To consolidate the discussion on instructional ideas, communicative reciprocal listening instruction is recommended for L2 listening instruction. Apart from instructional ideas, suggestions on how to develop a ‘considerate’ listening assessment that is in alignment with classroom instruction are also presented in this paper.

The purpose of this study is the review of the relationship between organizational trust and knowledge management in the national company of refining and distribution of the oil production in Kermanshah – Iran. This research is on the basis of the descriptive type, and the questionnaires are used in it. Aloonen et al., (2008). Questionnaires are used for organizational trust and for knowledge management evaluation is the questionnaires of Proset et al., Capacity of statistical society consist of 270 employee of the national company on the basis of the class accidental sampling among them, some of them have selected as a statistical sample and finally, 134 questioners have collected. Kolmogorov -Simonov test was used for the determining of the normality collected data, and to confirm the results of it. Hypothesis of the research were put in test container with spearman conjunction test. Results show meaning full and positive conjunction between trust and knowledge management. That is as trust of employees about their organization, increases; they should show much knowledge management.

Social responsibility of organizations has been the most important elements of philosophy, So that it is important to abide by organizations within the social identity theory, Satisfaction of stakeholders outside the organization to legitimate organizations will strengthen. Many of the behaviors and actions of managers and employees, was influenced by moral valuesrooted in ethics. Due to lack of work ethic in management, organizations, societies such as Iran, which was one rich in moral values? The advanced countries have a considerable distance, can create problems for organizations. In addition to increasing the social expectations of organizations, societies, such issues as the environment, women, children, minorities, disabled people, equal employment and staffing reductions, are more sensitive. Organizations ignoring these rights and ethics in dealing with external stakeholders can cause problems for the organization and the organization and action of legitimacy put it, profits, and thus affects the success of the organization. Poor work ethic, the attitude of jobs, organized and effective managers, can affect the performance of individual, group and organizational influence.
