The impact of heat source on magnetohydrodynamic oscillatory flow of a chemically reacting viscoelastic fluid in an asymmetric wavy channel is analysed. The governing flow equations are transformed into ODEs by utilizing proper nondimensional variables. The subsequent ordinary differential equations are solved analytically. The effects of different flow parameters on the fluid flow, thermal and species distributions as well as rate of heat and mass transfer coefficients are examined graphically. It is pointed out that the velocity of fluid is parabolic with extreme value along the channel centreline and minimum at the walls. The magnitude of fluid velocity increases with an increase in porous parameter and high heat transport of a system is due to the presence of oscillatory flow.

BACKGROUND: HMIS will incorporate a paradigm shift in health such as removing manual records and transformation of data through the complex structure of health departments in Tamilnadu. Thus developing a model of technology acceptance in HMIS contest is important and necessary in order to promote usage of the HMIS in rural health care system. OBJECTIVE: The papers purpose is to formulate a model of technology acceptance of Health Management Information System (HMIS) by generating and validating a research model that best describes rural health care workers usage behavior and behavior intention. METHODS: This research proposes a theoretical framework which is comprised of key determinants that influence usage behavior of HMIS together with moderator. It has been tested through different parametric test and confirmatory factor analysis. RESULTS: Data analysis shows that health workers innovativeness and voluntariness have a direct and positive influence on Technology Acceptance level and that the basic TAM hypotheses are fulfilled. HMIS usage behavior and behavior intention can be increased with factors that are effecting the successful implementation of HMIS when it remains high. CONCLUSIONS: This research enables health departments to know which aspects of their HMIS components and variables to improve. This shows that HMIS usage and health workers/staffs acceptance level are key tools in the success of HMIS. This research has seemed to be done at the right time and in the right place to the best of its kind. Development of model for assessing the acceptance level of users a paradigm shift in health removing manual records and transferring it into electronic information, standardization of health system and process, real time monitoring of hospitals performance, development of good communication and transformation of data through the complex structure of health departments in Tamilnadu.Health Industry has a significant role in Information System field, even though health industry has not yet received much attention in IS research, and the one of the important area of research in Information System is Technology acceptance. If IS theory is to diffuse more broadly [13], more attention to industry in theory development is needed. Many theories and models have been developed mostly in the U.S. Some of the most well-known theories/models were Technology Acceptance Model (TAM), TAM2, Innovations Diffusion Theory, Social Cognitive theory, Theory of reasoned action, Theory of planned behavior etc. Most of these theories of IS research has concentrated on a small subset of industries. Research findings from these industries cannot be generalized to other settings unless we assume that "nature is uniform" [10], that is unless we assume that differences among industries do not affect the applicability of IT knowledge and theory.In addition, there are some inconsistencies in the key determinants and moderators of technology acceptance, as to whether there are only determinants such as Perceived ease of use, Perceived ease of...
Education Management Information System (EMIS) is a widely acceptable and developing technology within the Information Technology field. The advancement in technology in this century is being collaborated with scientific invention or explorer and information strengthening or development. This paper presents the results and experiences gained from applying students oriented EMIS for monitoring and managing mental health. The Mental Health of students depends on the acquiring adequate knowledge on basic concepts within a time period or academic schedule. It's obviously significance to evaluate and appraise the stress stimulators as a challenge or threat. The theoretical framework for the study was designed for analyzing the stress stimulators, academic performance and EMIS accessibility. The sample examined in this study was stratified random sample from 75 students specifically all engineering college in Dindigul District of Tamilnadu. The primary factor is the academic stress stimulators that form one module of EMIS for each of the key variable such as curriculum & instruction related stressors, placement related, teamwork related and assessment related. The Mental Health related stress stimulators namely curriculum & syllabus, placement related, assessment related and team work related have a significant influence on academic performance by students in various institution. The important factor leading to the EMIS application in monitoring stress stimulators is curriculum & syllabus related and assessment related.
This research enables health departments to know which aspects of their communication strategies to highlight in order to get health personnel and other service providers to adopt IT. Perceived ease of use and IT application has a significant influence on health personnel's willingness to adopt HIT. This shows that health information and adoption by health personnel are key tools in the increase of future HIT. It is also recommended that health directors target some of their health campaigns to the more innovative beneficiaries. There are still too few studies that have analyzed the effects of innovativeness and IT adoption on behavior of health personnel. This work aimed to combine the influence of IT adoption, innovativeness, and the traditional TAM in order to construct an improved model for HIT acceptance. It will require an integrated model to do so.
