ERP PACKAGE EVALUATION, THE CASE OF SMEs KAVALA’s REGION
In this paper we want to examine how enterprise resource planning (ERP) systemseffects on small and medium-sized enterprises (SMEs) Kavala’s region. We consider several SMEsof our region, we use data from each SME and we form a questionnaire to secure more data fromthe enterprises. We weight up the factors that affect the choice of ERP. Also, we relate these factorswith basic characteristics of the specific SMEs of our region. Flexibility and functionality are themost important criteria of choosing an ERP system. Surprisingly, the cost is one of the lessimportant criteria. Also, minor effects have criteria such as brand, name and position of the vendor.Finally, we indicate issues for future research.ERP, SMEs, criteria evaluation
Automatic Discovery of Complementary Learning Resources
Proceedings of: 6th European Conference of Technology Enhanced Learning, EC-TEL 2011, Palermo, Italy, September 20-23, 2011.Students in a learning experience can be seen as a community working simultaneously (and in some cases collaboratively) in a set of activities. During these working sessions, students carry out numerous actions that affect their learning. But those actions happening outside a class or the Learning Management System cannot be easily observed. This paper presents a technique to widen the observability of these actions. The set of documents browsed by the students in a course was recorded during a period of eight weeks. These documents are then processed and the set with highest similarity with the course notes are selected and recommended back to all the students. The main problem is that this user community visits thousands of documents and only a small percent of them are suitable for recommendation. Using a combination of lexican analysis and information retrieval techniques, a fully automatic procedure to analyze these documents, classify them and select the most relevant ones is presented. The approach has been validated with an empirical study in an undergraduate engineering course with more than one hundred students. The recommended resources were rated as "relevant to the course" by the seven instructors with teaching duties in the course.Work partially funded by the Learn3 project, “Plan Nacional de I+D+I TIN2008-05163/TSI”, the Acción Integrada Ref.

Unpublished Mediterranean and Black Sea records of marine alien, cryptogenic, and neonative species
To enrich spatio-temporal information on the distribution of alien, cryptogenic, and neonative species in the Mediterranean and the Black Sea, a collective effort by 173 marine scientists was made to provide unpublished records and make them open access to the scientific community. Through this effort, we collected and harmonized
a dataset of 12,649 records. It includes 247 taxa, of which 217 are Animalia, 25 Plantae and 5 Chromista, from 23 countries surrounding the Mediterranean and the Black Sea. Chordata was the most abundant taxonomic group, followed by Arthropoda, Mollusca, and Annelida. In terms of species records, Siganus luridus, Siganus rivulatus,
Saurida lessepsianus, Pterois miles, Upeneus moluccensis, Charybdis (Archias) longicollis, and Caulerpa cylindracea were the most numerous. The temporal distribution of the records ranges from 1973 to 2022, with 44% of the records in 2020–2021. Lethrinus borbonicus is reported for the first time in the Mediterranean Sea, while Pomatoschistus quagga, Caulerpa cylindracea, Grateloupia turuturu, and Misophria pallida are first records for the Black Sea; Kapraunia schneideri is recorded for the second time in the Mediterranean and for the first time in Israel; Prionospio depauperata and Pseudonereis anomala are reported for the first time from the Sea of Marmara. Many first country records are also included, namely: Amathia verticillata (Montenegro), Ampithoe valida (Italy), Antithamnion amphigeneum (Greece), Clavelina oblonga (Tunisia and Slovenia), Dendostrea cf. folium (Syria), Epinephelus fasciatus (Tunisia), Ganonema farinosum (Montenegro), Macrorhynchia philippina (Tunisia), Marenzelleria neglecta (Romania), Paratapes
textilis (Tunisia), and Botrylloides diegensis (Tunisia)
Epidemiology, practice of ventilation and outcome for patients at increased risk of postoperative pulmonary complications
BACKGROUND Limited information exists about the epidemiology and outcome of surgical patients at increased risk of postoperative pulmonary complications (PPCs), and how intraoperative ventilation was managed in these patients.
OBJECTIVES To determine the incidence of surgical patients at increased risk of PPCs, and to compare the intraoperative ventilation management and postoperative outcomes with patients at low risk of PPCs.
DESIGN This was a prospective international 1-week observational study using the ‘Assess Respiratory Risk in Surgical Patients in Catalonia risk score’ (ARISCAT score) for PPC for risk stratification.
PATIENTS AND SETTING Adult patients requiring intraoperative ventilation during general anaesthesia for surgery in 146 hospitals across 29 countries.
MAIN OUTCOME MEASURES The primary outcome was the incidence of patients at increased risk of PPCs based on the ARISCAT score. Secondary outcomes included intraoperative ventilatory management and clinical outcomes.
RESULTS A total of 9864 patients fulfilled the inclusion criteria. The incidence of patients at increased risk was 28.4%. The most frequently chosen tidal volume (VT) size was 500 ml, or 7 to 9 ml kg1 predicted body weight, slightly lower in patients at increased risk of PPCs. Levels of positive end-expiratory pressure (PEEP) were slightly higher in patients at increased risk of PPCs, with 14.3% receiving more than 5 cmH2O PEEP compared with 7.6% in patients at low risk of PPCs (P < 0.001). Patients with a predicted preoperative increased risk of PPCs developed PPCs more frequently: 19 versus 7%, relative risk (RR) 3.16 (95% confidence interval 2.76 to 3.61), P < 0.001) and had longer hospital stays. The only ventilatory factor associated with the occurrence of PPCs was the peak pressure.
CONCLUSION The incidence of patients with a predicted increased risk of PPCs is high. A large proportion of patients receive high VT and low PEEP levels. PPCs occur frequently in patients at increased risk, with worse clinical outcome

The burden of disease in Greece, health loss, risk factors, and health financing, 2000–16:an analysis of the Global Burden of Disease Study 2016
Background: Following the economic crisis in Greece in 2010, the country's ongoing austerity measures include a substantial contraction of health-care expenditure, with reports of subsequent negative health consequences. A comprehensive evaluation of mortality and morbidity is required to understand the current challenges of public health in Greece. Methods: We used the results of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 to describe the patterns of death and disability among those living in Greece from 2000 to 2010 (pre-austerity) and 2010 to 2016 (post-austerity), and compared trends in health outcomes and health expenditure to those in Cyprus and western Europe. We estimated all-cause mortality from vital registration data, and we calculated cause-specific deaths and years of life lost. Age-standardised mortality rates were compared using the annualised rate of change (ARC). Mortality risk factors were assessed using a comparative risk assessment framework for 84 risk factors and clusters to calculative summary exposure values and population attributable fraction statistics. We assessed the association between trends in total, government, out-of-pocket, and prepaid public health expenditure and all-cause mortality with a segmented correlation analysis
Local analgesic effect of pethidine infiltrated intrafascially after total abdominal hysterectomy: A randomized, double-blind study
Objective: Surgical-site infiltration with local anesthetics is a key component of multimodal analgesia regimen for adequate postoperative pain management. This randomized, double-blind study was designed to evaluate the local analgesic efficacy of pethidine in patients undergoing total abdominal hysterectomy (TAH) through a Pfannenstiel incision. Materials and Methods: Patients were randomized into two groups. The first group received wound infiltration (WI) with 0.5 mg/kg pethidine, diluted in 15 ml normal saline, and injected in the fascial layer at the end of surgery, combined with a simultaneous intramuscular (IM) injection of 2.5 ml normal saline (WI group). The second group received WI with 15 ml normal saline combined with an IM injection of 0.5 mg/kg pethidine and diluted in 2.5 ml normal saline (IM group). All patients received general anesthesia following a standardized anesthetic protocol. Study end points were 24-h total morphine consumption and pain scores based on a visual analog scale (VAS) at rest and on coughing at 1, 3, 6, and 24 postoperative h, as well as sedation scores observed using a 0-10 numeric rating scale. Adverse effects from morphine uptake, such as nausea, vomiting, and the need for rescue antiemetics, were recorded as well. Results: Postoperative VAS assessments showed no statistically significant advantage between WI and IM method, while the total (24h) consumption of morphine was lower in the IM, compared to the WI group (27.2%). The latter demonstrated a consistently higher median sedation score at all assessed time points after the operation (P < 0.05); however, it was significantly different only at the 6 h time point. Conclusions: Local WI with pethidine after TAH did not reduce the total morphine consumption for the first 24 h postoperatively. Morphine consumption was lower in the IM group, compared to the WI group. Further studies are needed to assess the effectiveness of pethidine as a local anesthetic agent. © 2018 Journal of Natural Science, Biology and Medicine | Published by Wolters Kluwer - Medknow
Deep neuromuscular blockade in gynecological laparoscopic surgery: A review
Minimally invasive surgery has achieved remarkable progress during the last three decades in the field of operative gynecology. The intrinsic advantages of laparoscopy i.e. shorter operative time, less abdominal trauma, faster recovery and shorter hospitalization, combined with new advances in instrumentation, energy sources, and operative techniques, contributed to this shift towards laparoscopy for the operative management of a variety of gynecological conditions. One of the most important prerequisites for an effective and complications- free laparoscopic operation is the need to constantly maintain a good operative field. Concomitant advances in the area of anesthesia, like the use of objective neuromuscular monitoring and the introduction of new reversal agents have allowed clinicians to apply deep neuromuscular blockade (NMB) during laparoscopic operations with markedly reduced postoperative residual curarization. This evolution appears to contribute significantly to the establishment of a good operative field, especially during advanced and lengthy laparoscopic procedures, maintaining optimal conditions even when low-pressure laparoscopy (eight mmHg) is performed. The aim of this review is to present the principles of deep NMB and examine the possible benefits of its use during laparoscopy
