Enterprise Systems: Challenges and Opportunities for Information Systems Education

This paper presents a perspective on “learning” in managing information, applied to enterprise systems. As its name suggests, an enterprise system encompasses a total view of all parts (functions, sub‐systems) of the complete whole (organization, system). This approach of designing solutions for system component within the overall framework of the total system offers unique challenges and opportunities for designing, developing and implementing information systems. To meet its mandate, information systems education should offer a multidisciplinary learning environment especially in engineering and sciences curriculum where it is not adequately emphasized. A framework that is designed to deliver a comprehensive learning environment for the entire academic community has been proposed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/95457/1/j.2168-9830.2000.tb00490.x.pd

A rare case of leiomyoma of uterus with cystic degeneration

Leiomyoma of the uterus is the most common tumor of the female pelvis. The size of leiomyomas varies from microscopic to giant. Giant myomas are exceedingly rare. Here, we present a case of a woman with uterine myoma that had undergone cystic degenerative changes, mimicking an ovarian malignancy. It provided a lot of diagnostic challenge as even ultrasonography and CT scan were not confirmatory. Finally laparotomy was done keeping everything ready for the management ovarian malignancy. On laparotomy the mass was found to be leiomyoma of uterus with cystic degeneration

A comparative study of organic solvents, ionic liquids, surfactants and acids for liquid phase exfoliation of graphene

Graphene is the most widely investigated carbon nanomaterial having two-dimensional honeycomb lattice structure. Recently, it has attracted worldwide attention due to its remarkable electrical, thermal, mechanical, chemical and optical properties, which are highly suitable for various electronic device applications. Various methods of graphene synthesis have been utilized for the production of graphene each having its own advantages and disadvantages. Liquid phase exfoliation method uses top-down approach and has the advantages of being environment friendly, facile and economically viable. Liquid phase exfoliated graphene is highly suitable for making thin films for their potential applications in electronic devices such as thin films transistors, transparent electrodes, light-emitting diodes, supercapacitors, etc. In this paper, a comparative study of different exfoliation medium used for liquid phase exfoliation of graphene such as organic solvents, ionic liquids, surfactants, polymers and acids are described. Because of the usually low concentration of graphene (< 0.01 mg/mL) obtained from liquid phase exfoliation method, research has been done for enhancing the concentration. Recent progress made in enhancing graphene concentration in organic solvents by adding various additives is reported here. Finally, we discuss the challenges and future prospects of improving liquid phase exfoliation of graphene for modern electronics devices

A case control study of role of lipid profile in polycystic ovarian syndrome: is there any role in non-obese polycystic ovary syndrome?

Background: Polycystic ovary syndrome (PCOS) is characterized by hyperinsulinemia, impaired glucose tolerance, obesity, hyperandrogenism and abnormal lipid profile. Most of the studies involving lipid profile in PCOS are confounded by the factor of obesity. Here in our study we have tried to compare lipid profile in PCOS cases and healthy controls excluding obesity as a confounding factor.Methods: This is a case control study done between January 2013 to january2014 in VSS MCH, Burla, Odisha, India. The cases(n=50) diagnosed as PCOS based on Rotterdam's criteria and 50 controls of equivalent age group and body mass index without any endocrinopathy and not on hormonal therapy were selected. Lipid profile was compared for both the groups.Results: The Mean level of total cholesterol in the study and control group is 202.12±40.18 mg/dl and 171.48±17.74 mg/dl respectively and this is statistically highly significant (p value < 0.0001). Similarly the mean of triglyceride level in cases and controls is 162.38 ± 70.40 mg/dl and 131.46 ± 27.16 mg/dl respectively which is also statistically significant (p- value = 0.0046). In contrast to the above finding the change in mean level of HDL, LDL and VLDL is statistically not significant. So it’s found that the atherogenic lipid profile found in PCOS patients is independent of their age and body mass index.Conclusions: So we recommend that both lean as well as obese PCOS patients should be screened for lipid profile to prevent cardiac complications

Some Promising Areas for IS Research in the Healthcare Industry: Implications from a Case Study of Hospital Operation Room Scheduling

This study investigates the process of operation room scheduling at a Midwestern hospital. A comprehensive process map was developed to illustrate the existing scheduling process. Process simulation was conducted and bottlenecks were identified. Follow-up interviews with hospital administrators provide insights on the needs of integrating information systems for operation efficiency

Terahertz Detectors (THzDs): Bridging the Gap for Energy Harvesting

It is indispensable to integrate electronics with environment for better lives. Huge amount of solar energy, dark energy, and unused microwave energy is untapped till now due to insufficient availability of high frequency THz detectors. The difference between THz wave detection and THz electric field detection must be clear. THz wave detection connects the detection of explosives, drugs, astronomy, metals, and imaging applications, etc. On the other hand, THz electric field detection involves the conversion of electromagnetic (EM) radiations to usable DC power. The optimum choice of detectors for energy harvesting is a highly diverse area. The latter part is concentrated on the nonlinear behavior of the incoming radiations and has been highlighted also. In this chapter, metal‐insulator‐metal (MIM) diode detectors have been explored to become a best choice for high frequency detectors

A facile approach to fabricate graphene based piezoresistive strain sensor on paper substrate

Sensors, FETs and chemi resistors are few of the devices which show potential in the area of flexible electronics for health monitoring applications. In the present work, piezoresistive strain sensors based on graphite and graphene on cellulose paper substrate has been reported. Graphite sensor has been fabricated by rubbing pencil on paper and graphene sensor by directly coating graphene ink using paint brush. The resistance of the fabricated sensor increases with outwards bending and vice-versa, further the piezoresistive effect has also been evaluated by applying variable longitudinal stress. A comparative study of gauge factor (GF) depending upon different type of strains has been presented and it has been observed that the GF of graphene piezoresistive strain sensor decreases with increase in number of layers, the GF for graphene sensor is higher as compared to graphite sensor. Fabricated piezoresistive strain sensors may find applications as human body motion detection, gait analysis etc
