Computer Science: The Third Pillar of Medical Education  [PDF]
Frank Lau, Lindsay Katona, Joseph M. Rosen, Charles Everett Koop
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.326120
Abstract: In 2001, The Institute of Medicine (IOM) and the National Academy of Sciences (NAS) attributed substantial problems in the quality of American medicine to four domains: growing complexity of science and technology; the increase in chronic conditions; a poorly organized delivery system; and constraints on exploiting the revolution in information technology (IT). Although all of these domains have been improved by IT systems within the last decade, the U.S. health care systems has been slow to adopt these developments. We propose one way to combat such quality problems by incorporating a medicine-specific computer science (CS) curriculum as the third of Abraham Flexner’s pillars of medical education.
Possibility of Use of Noise Analysis for Identification of Reactor Conditions during Accidents  [PDF]
Tamas Janos Katona Katona
World Journal of Nuclear Science and Technology (WJNST) , 2013, DOI: 10.4236/wjnst.2013.33017

Knowledge and control of the thermo-hydraulic conditions in the reactor is required for the effective accident management. Dedicated and qualified for harsh environment instrumentation has to be in place for this purpose. Experience of the Fukushima Dai-ichi plant and the lessons learned from the European stress tests demonstrated that alternative and divers tools and methods are needed for the identification of reactor condition in extreme situations. In the paper the feasibility of development of an alternative accident monitoring via well-known noise diagnostics methods is proposed and demonstrated. The possibility of identification of reactor accident conditions using temperature and pressure fluctuations, noise of the neutron and gamma field is considered on the basis of research achievements in reactor noise. As an example the use of pressure fluctuations for accident monitoring is presented.

Modelling of Fatigue-Type Seismic Damage for Nuclear Power Plants  [PDF]
Tamás János Katona
Open Journal of Safety Science and Technology (OJSST) , 2012, DOI: 10.4236/ojsst.2012.22006
Abstract: Assessment of seismic safety of the nuclear power plants requires knowledge of plant fragilities. In the paper, preliminary analysis is made on use of the cumulative absolute velocity in modelling of fatiguetype seismic damage. The dependence of the cumulative absolute velocity on the strong motion parameters is analysed. It is demonstrated that the cumulative absolute velocity is an appropriate damage indicator for fatigue failure mode. Failure criteria are defined in terms of cumulative absolute velocity using various fatigue failure theories.

The role of virus infections in the pathogenesis of type I diabetes: A case report
Katona-?urekovi? Aniko
Medicinski Pregled , 2007, DOI: 10.2298/mpns0708397k
Abstract: Introduction. Coxsackie and mumps viruses are nowadays known to be pancreatropic viruses. However, the development of insulitis after viral infection is related to the genetic factor. Type I diabetes shows an association with the HLA antigens. HLA antigens are involved in cellular immune response and in the regulation of T-cell activation. Case report. A female patient, 23 years of age, was admitted to the Clinic of Endocrinology, Diabetes and Metabolic Disorders. The onset of diabetes was preceded by recurrent viral infections. Her blood glucose levels oscillated, and HbA1c was 7.9%. The presence of IgM antibodies to Coxsackie virus was detected (titer 320 m/ml). Conclusion. Each viral infection, especially in young people, should be taken seriously, and bed rest should be advised with symptomatic therapy. If we deal with patients with positive family history of diabetes, serum analysis should be performed for pancreatropic viruses, as well as follow up for several months checking the possible onset of diabetes.

Chinese Dragons and Indigenous Tricksters: Lessons for Leadership through an Intersection of People, Culture, Thought, and Practice  [PDF]
William G. Lindsay
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.96067
Abstract: During the course of recent research, this author has discovered similarities between aspects of classical Chinese philosophies and practices of those of traditional Canadian First Nations (Indigenous) peoples. Included in this has been a discovery that aspects of traditional leadership skills from both cultures intersect and are applicable to the work happening in a modern Canadian university. The author has also personally observed an overlap in the culture and lives of Chinese and First Nations people in modern British Columbia, continuing a 150-year tradition in this part of Canada. This paper—tying aspects of these two cultural and historic threads together—will consider the questions: What fascinating observations can be made and what personal, philosophical, and leadership lessons can be contrasted and compared, learned and shared through this historic intersection of peoples, cultures, thoughts, and practices? And can these over-lapping examples assist in solving larger problems of identity in the modern world?
The Environmental Significance of Bioindicators in Sewage Treatment
Judit Németh-Katona
Acta Polytechnica Hungarica , 2008,
Abstract: The presentation is about the significance of the bioindicators concerningenvironmental protection within the process of cleaning sewage. The existence of one ormulti-celled organisms indicates the presence, condition or absence of certain parts of thewater cleaning process. This way the optimal operation of the purifying appliances can bechecked continuously and controlled in an environment friendly way.
Biologically Qualified Environment, Ecologically Evaluated Conditions
Judit Németh-Katona
Acta Polytechnica Hungarica , 2008,
Abstract: The biological quality of an environment is defined as the condition reflecting thequantitative representation of living organisms in a given space and time. My lecturepresents how to qualify the environment of a biocenosis synbiologically, in other words, onthe supraindividual level. In this case, qualifying the environment in practice means thatboth the quantitative and qualitative composition of the biocenosis, and also the factorsresponsible for their distribution in space and time are considered and evaluated ascharacteristics. The ultimate goal of examining conditions is to evaluate, in other words, todetermine relevancy and significance in a given biocenosis. We are facing the problem thatin Hungary at present the biological survey methods are not standardized, and they arehighly varied. An environmental information system however cannot function beforeappropriate methods of biological survey are created. The lack of such methods wouldresult that one of the three major, organically complementary sources of information (i.e.the abiotic sphere, the biosphere, and human society) is completely missing. From adifferent aspect, ecological survey studies are different from the rest of environmentalsurvey studies, inasmuch as they study living organisms and their communities, thusinevitably utilizing the results of other environmental survey studies that evaluate differentcomponents. This indicates that the ecological section of all environmental survey studies isvitally important due to its complexity, and should be considered primarily decisive.
The significance of some anthropometric parameters and parameters ensuing from them in assessing cardiovascular risk in type 2 diabetes

Medicinski Pregled , 2006, DOI: 10.2298/mpns0602067k
Abstract: Introduction. Current clinical practice requires simple and available tools for cardiovascular risk assessment in diabetic patients. Material and methods. This study included 290 type 2 diabetics of both sexes. The following anthropometric parameters were measured: body mass index, waist circumference, sagital abdominal diameter, while ensuing parameters included: waist-to-stature ratio(WSH), ratio of abdominal sagital diameter to height (SADE), and conicity index. Metabolic status was evaluated based on lipidograms and HbAlc, and of cardiovascular parameters blood pressure was measured. Results. Female patients were obese, with central accumulation of fat, elevated blood pressure and lipid disorders such as hypo-HDL cholesterolemia. The applied anthropometric parameters and indicators ensuing from them (WSH, SADH and conicity index), are reliable indicators of elevated blood pressure in diabetic patients. Conclusion. The obtained results showed negative correlation with HDL cholesterol in women, which indirectly indicates to development of hypertension, as one of the most common diabetic complications. Central accumulation of fat with dyslipidemic disorder, characteristic of metabolic syndrome, is of highest importance. Sagital abdominal diameter (SAD) and WSH showed the highest correlation with lipidograms in females, whereas BMI was the best indicator in males. .
