Applied Research on Strategic Management of SMEs in Romania in the Digital Age

Abstract

Technological social and cultural changes generated by the digital age have a significant impact on both individual and society as a whole [1]. Is the context in which our research aimed at revealing the extent to which SMEs in our country are prepared to cope with these changes and can adapt to an environment increasingly turbulent and unpredictable [2]. Based on the three hypotheses of our scientific approach, the method used was the quota for proportional distribution by counties, respectively the optimal-layered model for the distribution by fields of activity. As a means of investigation we used a questionnaire with 26 questions answered by 598 SMEs, the purpose being represented by identifying, on the one hand, the used methods of strategic management and, on the other hand, the uptake of digital means by them. The responses from the distribution of the questionnaire were analyzed by various statistical and econometric methods. In a first stage we used descriptive statistics to identify peculiarities of respondents to compare different homogeneous groups. In the second stage of analysis to determine statistical deductive conclusions, we used the analysis of variance, correlation and linear regression and ANOVA using SPSS software for Windows 16.0. Following validation of the research hypotheses, in the end of the work we formulated a series of proposals to improve the strategic management of SMEs in Romania in the digital age.

Empirical Study Regarding the Influence of Communication Upon the Purchasing Decision

Abstract

The aim of the present study is to emphasize the influence of communication upon the customer’s purchasing decision. This objective is translated through determining the change of products in the sales’ structure using communication by omission. The study is focused upon the purchasing selection between two similar products by the subjects included in the study. The difference between the two products lies in the customers’ care for the environment. Thus, one of the two products does not pollute, in the conditions in which the application with care and attention is applied (this being expressed through a price difference compared to the other, polluting, product). The study has two phases in order to compare the sales structure in the situations in which it is used the communication through omission (in the second phase of the study) with the sales structure when the communication through omission is not used. The hypothesis according to which the purchasing process takes place according to the care for the environment and not necessarily according to the direct utility allocated to some apparently similar products has been tested through econometric instruments.

Body Fat Distribution in Women with Polycystic Ovary Syndrome

Abstract

Background and Aims. Most women with Polycystic Ovary Syndrome (PCOS) are thought to have an abdominal body fat distribution, regardless of body mass index (BMI). The objective of our research was to compare body fat distribution between PCOS cases and BMI/age matched healthy control women. Materials and Methods. We compared 102 women with PCOS and 120 healthy female patients matched for age and BMI (retrospective review of the medical records). Visceral fat area (VFA) was measured by bioelectric impedance. Results. No significant differences were noted between the PCOS group and controls regarding total cholesterol, LDLcholesterol and triglycerides levels. Mean HDL-cholesterol concentration was significantly lower in the PCOS group (p=0.03). Mean fasting serum insulin and calculated HOMA-IR were higher in the PCOS group (14.2±7.2 vs. 9.1±4.1μU/mL, p<0.001, and 3.1±1.8 vs. 2.3±1.1, p=0.01 respectively). VFA was similar in patients with PCOS and in the control group. Conclusions. Obese women with PCOS have no preponderant accumulation of visceral fat, compared with weight/age-matched controls. Our data suggest that the distribution of fat to visceral depots is unlikely to be the entire explanation for the metabolic abnormalities observed in women with PCOS.

Suport System for the Management of the Sabanejewia aurata (De Filippi, 1863) Populations of the ROSCI0227 – Sighișoara-Târnava Mare

Abstract

ADONIS:CE was used to design a computer model for the management of Sabanejewia aurata (De Filippi, 1863) populations in the Natura 2000 site of Sighişoara-Târnava Mare (ROSCI0227). The recommended management model is based on the environmental needs of the species, inventoried according to the local habitats, as well as the indicators of conservation status and relevant management measures, and takes into account human pressures and threats identified in the research area. Such computer models were established for all protected fish species found at the site ROSCI0227.

Acute myocardial infarction with multiple mechanical complications

Abstract

The rupture of the inter-ventricular septum is a rare, but extremely severe mechanical complication of the acute myocardial infarction, which in most cases of no immediate surgery is fatal (30 days death rate – 80%). The incidence of the septum ventricular defect post-acute myocardial infarction was 1-3% in the period before crash injury therapy, dropping to 0.2% after introducing the thrombolytic treatment.

The acute mitral failure and the septum ventricular defect are two mechanical complications of the acute myocardial infarction associated with high death rate, regardless of the progress made in medical and surgery therapeutic approach.

This paper highlights the peculiarities of a clinical case like the acute myocardial infarction as the first manifestation of heart disease in a patient with no history of cardiovascular disease but with risk factors (obesity, dyslipidemia, hypertension), the ECG evident changes in the anterior territory and more discrete in the inferior territory, which established the initial diagnosis to be myocardial infarction and the presence of two mechanical threatening complications: ventricular septal flaw and acute mitral failure through posterior papillary muscle incomplete rupture.

Neurologic Manifestations of Infective Endocarditis

Abstract

Infective endocarditis is an infection of the endocardial surface of the heart. Usually, it affects one or more heart valves or an intracardiac device. Neurologic events (silent or symptomatic) account for 20 to 40% of all patients with infective endocarditis.

We are presenting the case of a 57 -year-old man with cardiovascular risk factors admitted to our clinic for aphasia. His medical history included a recent stroke and small fiber neuropathy with a gradual onset for the past six months. Despite extensive investigations, no cause for strokes and neuropathy could be found. To identify a potential source of embolism, a transoesophageal echocardiography was performed. It revealed vegetation attached to both aortic and mitral valves. Blood cultures were positive for Streptococcus gallolyticus. The patient underwent emergency aortic and mitral valve replacement and a 6-week course of antibiotic treatment with ceftriaxone and gentamicin with the improvement of both aphasia and peripheral neuropathy.

Central nervous system complications such as encephalopathy, seizures, stroke or severe cerebral hemorrhage are commonly described in infective endocarditis, but peripheral nervous system involvement is rarely reported in the literature. Although no cause for neuropathy has been found, it is difficult to asses whether it was a complication of the infective endocarditis.

Alien Species of EU Concern in Romania

Abstract

Of the 37 species of the European Union concern eight are already present and two present a future potential risk for Romania. This paper brings updated information regarding these species in Romania. The presence of eight invasive alien species of concern to the European Union have already been recorded in Romania: two plant species Cabomba caroliniana and Heracleum sosnowskyi, two crustaceans Orconectes limosus and Eriocheir sinensis, two fish species Pseudorasbora parva and Perccottus glenii, one reptile Trachemys scripta and one mammal Myocastor coypus. Other two species of Union concern (Lithobates catesbeianus and Procyon lotor) may soon become invaders in Romania. We emphasize the urgent need to assess their current distribution and impact or potential to establish and possible impact at national level.

Assessing the Peripheral Sensitivity of Newly Diagnosed Type 2 Diabetes Mellitus Patients Using Caseivsystem and Classic Methods

Abstract

Background and Aims: A complete evaluation of complications should be done each time a new case of Type 2 Diabetes Mellitus (T2DM) is diagnosed. A good screening of complications will be the background of an oriented treatment. Our aim was to assess the vibratory and thermal sensitivity using a Computer Aided Sensory Analyzer (CASEIVSystem) in newly diagnosed T2DM patients and to compare it with the threshold determined by classical methods. Material and Methods: We sequentially enrolled 260 patients with newly diagnosed T2DM. The threshold of peripheral vibratory and thermal sensitivity was comparatively assessed using CASEIVSystem and classic tools. Other neurological scores were obtained from patients. Results: The vibratory threshold was abnormal in 56.92% (hand) and respectively 75.00% (foot) of subjects. Altered perception for the thermal threshold was registered in 76.15% and, respectively, 76.92% of subjects for the same sites. The 10g-monofilament exam was positive for 28.46% and the 128Hz-tuning-fork exam was positive for 20.38% of the examined patients. Mean time for a complete CASEIVSystem exam was around 27.23±9.34min vs. 3.21±0.24min (p<0.05) for a classic exam. Conclusions: In our study, CASEIVSystem allowed the assessment of the vibratory and thermal thresholds. The time needed for investigation renders this tool difficult to use in a time effective manner

Comparative Study Between the Papillary Muscles of the Right Ventricle and the Left Ventricle Papillary Muscles

Abstract

We used formalinized heart dissection obtained from forensic laboratory in Constanta, analyzing the papillary muscles and their tendon chordae. We studied at the papillary muscles the number of forms that could be in single or multiple muscular bodies, encountering more than five body muscles in a papillary muscle group. We measured using caliper graduated in millimeters, the height of each papillary muscle body (from the base to its upper end) and its thickness at the base and at its upper extremity. Chordae tendon we examined in terms of their origin and number at the level of each papillary muscle, the dimensions (length and thickness), orientation and how they end at the atrioventricular valves. We noted the presence of „false”chordae tendineae, which were disposed between the papillary muscle and the ventricular wall. The results were compared with data in the literature that I had the opportunity to consult

Comparison Between the Anterior Ventricular Wall Thickness, Left and Right, and Considerations on Trabecular System of the Two Ventricles

Abstract

In recent decades (late twentieth century), have been reported multiple anatomical variations in relation to the concepts described classic, so what once was described as an anatomical variant in some cases has become predominant, not quite often proposing a revision of international anatomical terminology.

This article is specifically addressed on the morphology of the papillary muscles of the two ventricles, describing the differences between the left and the right anterior ventricular walls.
