Optimizing the stake holder’s perspective on enhancing the service quality in health care
For the success of health care organizations, accurate measurement of health care service quality is as important as understanding the nature of the service delivery system. Without a valid measure, it would be difficult to establish and implement appropriate tactics or strategies for service quality management. Experts have struggled for decades to formulate a concise, meaningful and generally applicable definition of the quality of health care. However, the complexity and variability of many definitions are very confusing even to experts. Patients, service providers and other parties involved in the process of health care service delivery, understand and describe service quality in different ways. Different perspectives on health care quality lead to different expectations and different methods of quality measurement. Patients tend to evaluate health care quality according to the responsiveness to their specific needs. Most patients define quality as efforts of physicians to do everything possible for a patient. Patient’s expectations about the health care system may differ from those of health care professionals and managers. On the other hand, patients cannot evaluate many technical aspects of health care service quality. Physicians can provide a high level technical quality but still be rated low by patients because of the lack of humanity, responsiveness or satisfaction. For physicians and other health care providers measurement of service quality has typically been driven by medical outcomes. However, outcomes indicative of quality may differ for a patient and physician. Health care administrators often use managerial input measures such as the average number of nursing hours required for an outpatient surgery. This research paper aims to explore the ways and means towards optimizing the competing stake holders perspectives on enhancing the service quality in health care.Service quality; Healthcare; Optimization; India;
EVALUATION OF IN VITRO ANTIOXIDANT AND ANTIDIABETIC POTENTIALS OF DIFFERENT FRACTIONS OF MAYTENUS HEYNEANA ROOT EXTRACT
Objective: In an attempt to explore herbal drug which may become useful in the prevention of diabetes and antioxidant potential by the ethanol extracts of Maytenus heyneana (MH) root belonging to the family Celastraceae and their different fractions were studied.Methods: Different fractionation was done using chloroform, ethyl acetate, and methanol on ethanolic extract of MH and preliminary phytochemical analysis was done by standard methods to identify the presence of important compounds. In vitro antioxidants activities were carried by 2,2-diphenyl- 2-picrylhydrazyl (DPPH) and 2,2-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS) cation radical scavenging assays. For antidiabetic potential, α-amylase and α-glucosidase enzyme inhibitory studies were carried on different fractions.Results: Phytochemical studies show the presence of alkaloids, flavonoids, phenols, cardiac glycosides, and terpenoids in all fractionations; however, tannins and quinones were present in ethyl acetate fraction and saponins in methanolic fraction. For antioxidant activity, ethyl acetate fraction shows concentration of the sample causing 50% inhibition (IC50) values in 22.31 μg/ml and methanolic fraction shows in 12.82 μg/ml concentrations for DPPH and ABTS radical scavenging assay, respectively. In case of antidiabetic activity, methanolic fraction offered significant result in inhibitory action of α-glucosidase and also for α-amylase assay IC50 (5.28 and 3.14 μg/ml) than other fractions.Conclusion: From the results of our studies, it can be concluded that MH shows antidiabetic and antioxidant values and methanolic fraction of MH could be possessed potential constituents in the prevention of diabetes and antioxidant than other fractions. However, further studies are required to validate

The primary objective of this paper is to describe how web services can effectively manage educational resources by leveraging Quality of Experience and to develop an effective E-learning recommender system in the context of web services that help the user choose a course based on his needs in terms of availability, cost, and reputation
Active Vibration Control of Structures using an Impedance Matching Control Technique
Active vibration control of structures has gained a lot of interest in recent years. This paper presents an active vibration control methodology of a structure using piezoelectric actuators. The proposed methodology is useful in practical applications where the system to be controlled is difficult to model due to the presence of complex boundary conditions. The impedance matching control technique uses a power flow approach wherein the controller is designed such that the power flow into the structure is minimized. The system transfer function is obtained from the experimental collocated actuator/sensor pair data using Eigen Realisation Algorithm (ERA). The controller is designed for the system transfer function according to impedance matching theory. The above approach is targeted towards the vibration control of wind tunnel stings, which suffer from flow-induced vibration. A wind tunnel sting model is designed and fabricated for this study. The real time implementation of the impedance matching controller has been carried out using dSPACE® Digital Signal Processor (DSP) card. The results are encouraging and demonstrate the feasibility of applying this technique in the wind tunne
ARCUATE FORAMEN OF ATLAS VERTEBRA
ABSTRACTThe Arcuate foramen is a bony arch which connects the posterior end of the superior articular fossa with the posterior arch of atlas. In case of presence of arcuate foramen the vertebral artery follows the normal course but it has to traverse through the osseo fibrous ring (arcuate foramen).Aim & ObjectivesTo determine the height, width, and area of arcuate foramen and to determine the morphometric difference between the transverse foramen and the canal formed by bony bridges over the vertebral artery of the atlas vertebra.Materials & MethodsA total of 75 dry human atlas vertebrae were taken for the study. These vertebrae were examined carefully for the presence of arcuate foramen. Measurements of the maximum dimensions of the arcuate foramen and foramen transversarium were taken. Area of the arcuate foramen was calculated. Differences in dimension of arcuate foramen  and foramen transversarium were compared. Side differences of arcuate foramen were compared using the unpaired Student's t test.ResultsThe dimension of arcuate foramen of both sides as compared with dimension of foramen transversarium was found to be more, so the chance of compression of vertebral artery on both sides was less. The percentage of occurrence of arcuate foramen was 2.25% (bilateral) and ponticles was (1.5%) unilateral. ConclusionThe dimension of arcuate foramen was more when compared to foramen Transversarium dimensions so the chances of compression of vertebral artery would be less. The knowledge of these foramina may be important for orthopedic surgeons, radiologists, neurosurgeons, and anthropologists. KEYWORDS -Ponticulus Posticus, Arcuate Foramen, Atlas Vertebra, Foramen Transversarium
Post-Modern Feminist Ideology in Mahesh Dattani’s Where There’s a Will and Final Solutions
A true art is not meant for teaching and preaching. Its primary function is to give delight; its purpose is chiefly aesthetic. Only a writer, who maintains a perfect blending of both feeling and form, can push upward the art at its zenith. Mahesh Dattani exposes the illusion of perfect and complete control over the family for a longer period. Here the question arises in our mind why a man aspires too much for authority and power. Does it signify any value of life? Apparently it doesn’t attach any meaning to human existence. Nor does, it helps in improving quality of human life. Dattani is convinced that it is an attempt to make one-self secure and survive. So, man’s drive for the domination arises out of his own apprehension of insecurity. The dramatist mainly reflects on the issues of gender discrimination and evil of patriarch along with host of other issues like father-son, husband-wife relationship, evil of capitalism in the post colonial purview.
Outcomes of limb salvage surgery in patients with extremity osteosarcoma.
INTRODUCTION :
Osteosarcoma is the most common malignant neoplasm of
bone1 . It occurs most often in bones around knee joint and
humerus of young people. Due to rapid and aggressive nature of
the disease, the traditional treatment for osteosarcoma was
amputation of the affected limb. In the 1970s, two year survival
rates were fifteen to twenty percent2. However over the past 3
decades, the prognosis for these patients has changed dramatically.
The development of chemotherapy agents have revolutionised the
treatment of osteosarcoma by reducing the mortality. In addition
the advances in imaging and new materials have provided the
surgeon broader range of operative alternatives.
AIMS AND OBJECTIVES :
1. To study long term survival of patients with extremity
osteosarcoma treated by limb salvage surgery.
2. To identify prognostic factors influencing survival.
3. To identify risk factors for local recurrence.
4. To assess functional assessment of patients following limb salvage Surgery.
CONCLUSION :
Treatment of osteosarcoma has seen a paradigm shift in the
management and today limb salvage surgery is possible in a
majority of patients. Survival outcomes are excellent in our
study and in par with international standards.
Needle biopsy is the preferred method of obtaining diagnosis,
preferably to be done by the centre planning the definitive
treatment.
Tumor response to neoadjuvant chemotherapy is the most
important and valid prognostic factor predicting survival.
Extensive soft tissue involvement and tumor necrosis following
neoadjuvant chemotherapy were found to be risk factors, for the
increased local recurrence, that has been observed in this study.
In patients with extensive soft tissue extension, limb salvage
surgery can be considered if technically feasible, although they
have decreased survival similar to patients undergoing
amputations. Our study has got its limitations as the results of
the analysis of this group of patients are not statistically
significant and due to lesser number of patients. The influence
of this subgroup of patients undergoing limb salvage surgery,
on local recurrence and survival needs to be validated in a
prospective study involving more number of patients.
Functional outcome after limb salvage surgery is excellent in
our patients
Haematology and biochemical parameters of different feeding behaviour of teleost fishes from Vellar estuary, India
Haematological parameters have been recognized
as valuable tools for monitoring fish health. Haematological
and serum biochemical parameters were studied and
compared different feeding behaviour of teleost fishes.
Three marine teleost fishes, Lates calcarifer (carnivores),
Mugil cephalus (omnivores) and Chanos chanos (herbivores),
were carried out in order to find out a normal range
of blood parameters which would serve as baseline data for
assessment of the health status of the fish as well as
reference point for future comparative surveys. Blood
parameters such as red blood cell count (RBC) and white
blood cells count (WBC), haemoglobin, haematocrit, mean
cell haemoglobin concentration (MCHC), mean cell volume
(MCV), mean cell haemoglobin, glucose, protein,
cholesterol and urea were estimated from teleost fishes of
different trophic level. Statistical analysis revealed that
differences in haematological parameters between marine
fish were significant (P<0.01)
