Nanotechnologies and global survival
Sociologija , 2012, DOI: 10.2298/soc1201037m
Abstract: The rapid development of science and technology from the mid-20th century, on one hand, and increasing world population as well as decreasing of natural resources on the other has raised the risk of escalating social conflicts. Regarding this facts, it is inevitable to admit that the future of mankind lies in acceptable moral and social implementation of this technologies. Having that in mind, many questions have been generated about responsible applications of nanotechnologies: about the positive and negative effects of their usage, about patterns of their socio-spatial distribution both at global and national level, about economic development of states who use those technologies, and their possible effect of individual health and biosphere preservation. Regarding those questions, it is necessary to use knowledge of nature science as well as knowledge of philosophy, sociology, etc., in order to analyze the level of development and life conditions in human communities and differentiate between “mere”, “miserable”, “idealistic“, “irresponsible“ and “acceptable“ survival. Starting from sociological context and following Potter’s concepts, this article argues for the concept of consurvivality that is durable, acceptable, sustainable, realistic and global.
Arguments pro and con of the 'enhancement' of human beings through genetic intervention
Sociologija , 2010, DOI: 10.2298/soc1001075m
Abstract: The paper aims to explain two basic standpoints regarding the enhancement of human beings through genetic engineering. Savulescu seems to be starting from a technoprogressive, (neo)liberal orientation, while Fukuyama's position implies a step back - to (bio)conservatism, returning to the natural human rights. These opposing general attitudes reflect the same aspiration - towards greater control and monitoring by the state for the benefit of individuals and (or) humankind. While Fukuyama justifies the narrow use of biotechnology for the purpose of therapy and prevention of disease, so far Savulescu goes a step further, understanding 'enhancement' to include increasing the length and quality of life, and focuses exclusively on genetic intervention for this purpose. Discussing the same problems Fukuyama lists several reasons why we should limit the use of biotechnology - reasons of religious, utilitarian and philosophical nature. In this paper, arguments for and against genetic intervention are discussed, while cited examples are commented ad hoc.
The myth of the moral enhancement: Back to the future?
Filozofija i Dru?tvo , 2012, DOI: 10.2298/fid1202111m
Abstract: This text tries to shed some light on the origin of the idea of moral enhancement, on its epistemic and moral foundations. This requires a comparative analysis of similar ideas present in various trends of bioethics today - the analysis of the very roots of Poter’s global bioethics, the idea of moral enhancement, as well as the break between advocates of moral enhancement and John Harris, their transhumanist colleague, with whom they used to share the same perspective. In this article we identify some basic starting points, similarities and differences between global bioethics and moral enhancement, and draw lines of demarcation between transhumanism and moral enhancement.

Abstract: Introduction. Consequences of heroin abuse include organic damage of cerebral structures. The level of impairments is in a direct and positive relation with the length of heroin abuse. Objective. The aim of this research was the evaluation of the reaction time with heroin addicts with different length of substance abuse. Methods. Research method: 90 examinees were divided into three groups with relation to the length of heroin abuse. Data collection included a questionnaire referring to socio-demographic and addictive characteristics. A specially designed programme was used for the evaluation of reaction time to audio/ visual signal. Results. In relation to the reaction time as overall model, the difference between examinees with different length of heroin abuse can be found on the marginal level of significance (F=1.69; df=12; p=0.07). In visual modality, with the increase of length of heroin abuse leads to a significant prolongation of simple (the first visual sign: F=3.29; df=2; p=0.04) and choice reaction time (the second visual sign: F=4.97; df=2; p=0.00; the third visual sign: F=3.08; df=2; p=0.05). Longer heroin consumption also leads to the prolongation of the simple (the first auditory task: F=3.41; df=2; p=0.04) and the complex auditory reaction time (the second auditory task: F=5.67; df=2; p=0.01; the third auditory task: F=6.42; df=2; p=0.00). Conclusion. Heroin abuse leads to the prolongation of both simple and choice reaction time in visual as well as auditory modality. The average daily dose of opiates was the most important predictor of the abovementioned cognitive dysfunction.

Abstract: Introduction. Combination of ACE-inhibitors with angiotensin-II type 1 receptor antagonists could provide better blockade of RAAS system compared with monotherapy. Objective. The aim of this study was to evaluate hemodynamic and neurohumoral effects at rest and during exercise of Candesartan cilexetil as add-on therapy to ACE-inhibitors in patients with heart failure NYHA class III to IV. Methods. This was a prospective, randomized, double-blind, placebo-controlled, parallel group study. Thirty-five patients received either Candesartan 8 mg/16 mg (1st and 2nd week/ of 3-24) or placebo as add-on therapy to their previous ACE-inhibitor during a 24-weeks treatment period. Results. Peak aerobic capacity remained constant in the Candesartan group of patients (0.06±1.43 mL/min/ kg) and slightly decreased in the placebo group (-1.10±1.51 mL/min/kg), without a statistically significant difference between the groups (p=0.13). Exercise time showed a relevant increase in the Candesartan (31.9±58.5 sec) and a significant decrease in the placebo group (-25.9±85.9 sec) compared to baseline value. The difference between the studied groups was statistically significant (p<0.001). Relevant differences between the two groups were observed in the changes of right atrial pressure at rest (Candesartan: -1.9±1.7 mmHg, placebo: 1.0±2.7 mmHg, p<0.01), pulmonary capillary wedge pressure at rest (Candesartan: -3.1±3.8 mmHg, placebo: 0.2±4.6 mmHg, p<0.05) and systemic vascular resistance at maximum exercise (Candesartan: -141.9±253.3 dyne sec/cm5, placebo: 47.3±221.0 dyne sec/cm5, p<0.05). Conclusion. The efficacy of CHF treatment of congestive heart failure was moderately improved by Candesartan as add-on therapy to ACE-inhibitors.

Abstract: Moxonidine, a new centrally active imidazoline receptoragonist, might represent a new clinically beneficial antihypertensive principle. This is the first in vestigation regard ing the effects of moxonidine on coronary and sys temic hemodynamics, metabolic markers of ischemia and neurohumoral parameters. We stud ied moxonidine (single dose of 0.4 mg p.o.) in 22 pa tients with hypertension (WHO I-II) and left ventricular (LV) hypertrophy, ST segment depressions during exercise, pectanginal complaints and negative coronarograms. Assessments included arterial blood pressure, cardiac out - put, pulmonary artery pressure mean (PAPm), pulmonary capillary wedge pressure (PCWP) and coronary sinus flow (CSF) by intravascular Dopp ler tech nique. The average moxonidine-induced parameter changes (p<0.05, at least), at about 2 hours later, were as fol lows: a de crease in systolic/diastolic pressure by 28/10 mmHg, and in heart rate by 5 bpm, associated with a decline of PAPm by 17% and of PCWP by 26%. LV-work was re duced by 26%, MVO2 by 18% and CSF by 16%. Average peak velocity in CS fell by 18% and coronary flow reserve (with adenosine) in creased by 12%. CS-02 sat u ration rose by 4%, accompanied by an in crease in lactate extraction by 17%, a decrease in norepinephrine spillover by 30% and in arte rial endothelin by 20%. Conclusion: moxonidine produces clinically relevant sympathicolysis with beneficial effects on hemodynamics, coronary circulation and neurohumoral parameters.
Quantum economics

Panoeconomicus , 2011, DOI: 10.2298/pan1102267v
Abstract: The globalization is breaking-down the idea of national state, which was the base for the development of economic theory which is dominant today. Global economic crisis puts emphasis on limited possibilities of national governments in solving economic problems and general problems of society. Does it also mean that globalization and global economic crisis points out the need to think about new economic theory and new understanding of economics? In this paper I will argue that globalization reveals the need to change dominant economic paradigm - from traditional economic theory (mainstream) with macroeconomic stability as the goal of economic policy, to the “quantum economics“, which is based on “economic quantum” and immanent to the increase of wealth (material and non-material) of every individual in society and promoting set of values immanent to the wealth increase as the goal of economic policy. Practically the question is how we can use global market for our development!

Panoeconomicus , 2008, DOI: 10.2298/pan0801115v
Abstract: Are economic freedoms going to clear our way to prosperity? Is the growth of economic freedoms our path to prosperity? Is it in the base of the new understanding of development? If yes, what will necessarily have to be changed in the economic practice of every country and whole world in general? What will be changed in economic theory? What are potential consequences of an attempt to offer resistance to the new concept of development? These are just some of the questions discussed in this paper, whereas the starting point is the economy and economic development of Montenegro.

Journal of Agricultural Sciences , 2009, DOI: 10.2298/jas0902166s
Abstract: The Serbian animal feed industry confronted with insufficiently used capacities and considerable price oscillations of raw materials and final products has gone through a substantially long period of dynamic development. The objective was to analyze production capacities, spatial distribution, changes in feed manufacture output and raw materials used, import and export, changes in the number of employees, etc. Major attention was focused on indices of the financial and economic structure in order to define the position of feed mills in relation to the sector and the economy as a whole. In addition, the aim was to analyze the possibility of improving feed mill management. Mathematical and statistical models were developed with special reference to the needs of some types and categories of animals, raw materials at disposal, capacities and requirements with regard to feeding stuffs. The linear programming model was used in order to contribute to the successful management of all the phases in the production chain. .
