BOOK REVIEW ON CITIES AS SUSTAINABLE ECOSYSTEMS: PRINCIPLES AND PRACTICES. Authors: Peter Newman and Isabella Jennings

The book is a positive image of how cities can contribute not only to a better economic and social future but also a profoundly better ecological future. "Cities as Sustainable Ecosystems" shows how cities can begin to reintegrate into their bioregional environment and planned taking into account nature's organizing principles. Therefore, professor Peter Newman and Isabella Jennings reassess urban design by exploring flows of energy, materials, and information, along with the interactions between human and non-human parts of the system. "Cities as Sustainable Ecosystems" describes aspects of urban ecosystems, being a powerful model for urban redevelopmentSustainable Ecosystems, urban development, urban ecosystems

PROVOCARILE IMPLEMENTARII GUVERNARII ELECTRONICE

Implementarea viziunii guvernarii electronice nu doar va aduce in fata noile provocari ale urmatorului deceniu, dar este posibil sa ia unele provocari mai in serios. Toate acestea sunt legate de nevoia de conducere politica si strategica, de transformarea structurala care trebuie sa se realizeze printr-o abordare care il centreaza pe cetatean, nevoia pentru operationalitate si standardizare si pentru implementarea instrumentelor tehnologice si metodologice. In constructia viziunii guvernarii electronice in U.E cele mai importante provocari sunt cele politice, social-economice si tehnologice. Unele dintre provocarile identificate sunt deja cunoscute si au fost bine documentate. Exemple ca acestea sunt: interoperabilitatea si standardizarea, nevoia pentru reingineringul birourilor din spate si nevoia pentru comitete politice si conducere politica.guvernare electronica, abordare orientata pe cetatean, standardizare

EVALUAREA CALITATII SITE-URILOR WEB ALE PRIMARIILOR ORASELOR DIN ROMANIA

Dezvoltarea societatii informationale, a retelei informatice, cresterea numarului de utilizatori si a volumului de informatii necesare publicului, fac ca mediile de transmitere si de difuzare a cunostintelor si informatiilor sa fie cat mai diverse dar si cat mai atractive si mai usor de descifrat si utilizat. In aceste conditii, institutii de drept public sau de drept privat aleg sa sintetizeze si sa-si impartaseasca informatiile cu ajutorul site-urilor web. Astfel, pentru a analiza calitatea site-urilor web, pentru a vedea in ce masura acestea raspund cerintelor utilizatorilor ne propunem sa intocmim o metodologie bazata pe procedurile si algoritmii utilizati in cadrul metodei WebQEM, metodologie care se va finaliza cu o serie de recomandari privind proiectarea s realizarea site-urilor web. Domeniul pe care ne propunem sa-l analizam il reprezinta site-urile web ale primariilor oraselor.societate informationala, site-urile web ale oraselor, metoda WebQEM.

TENDINTELE SOCIETATII INFORMATIONALE IN ROMANIA

Calculatoarele si Internet-ul au schimbat in mod semnificativ modul in care cetatenii pot avea acces la serviciile publice. Societatea informationala este din ce in ce mai prezenta in toate activitatile sectorului public inclusiv prin aplicatii complexe de e-Government. Guvernul Romaniei promoveaza diverse proiecte care sa faca din serviciile electronice un instrument de reforma a administratiei publice. Primele rezultate sunt incurajatoare dar arata ca aceasta reforma trebuie sa aiba loc si la biroul fiecarui functionar public.societatea informationala, guvernare electronica, servicii electronice

CONDUCEREA ORASULUI VIITORULUI ASISTATA DE MODELE DE SIMULARE URBANA

Sistemele urbane devin din ce in ce mai complexe, la fel si structurile si normele politice si sociale, sistemele de infrastructura si tehnologiile elaborate. Se impune in acest context elaborarea unor modele de simulare urbana operationale care sa conduca la o imbunatatire a calitatii deciziilor privind politicile din domeniul urban si implicit la dezvoltare urbana durabila.oras "inteligent", dezvoltare urbana durabila, simulare urbana, model de simulare urbana

Preoperative Immunocite-Derived Ratios Predict Surgical Complications Better when Artificial Neural Networks Are Used for Analysis—A Pilot Comparative Study

We aimed to comparatively assess the prognostic preoperative value of the main peripheral blood components and their ratios—the systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR)—to the use of artificial-neural-network analysis in determining undesired postoperative outcomes in colorectal cancer patients. Our retrospective study included 281 patients undergoing elective radical surgery for colorectal cancer in the last seven years. The preoperative values of SII, NLR, LMR, and PLR were analyzed in relation to postoperative complications, with a special emphasis on their ability to accurately predict the occurrence of anastomotic leak. A feed-forward fully connected multilayer perceptron network (MLP) was trained and tested alongside conventional statistical tools to assess the predictive value of the abovementioned blood markers in terms of sensitivity and specificity. Statistically significant differences and moderate correlation levels were observed for SII and NLR in predicting the anastomotic leak rate and degree of postoperative complications. No correlations were found between the LMR and PLR or the abovementioned outcomes. The MLP network analysis showed superior prediction value in terms of both sensitivity (0.78 ± 0.07; 0.74 ± 0.04; 0.71 ± 0.13) and specificity (0.81 ± 0.11; 0.69 ± 0.03; 0.9 ± 0.04) for all the given tasks. Preoperative SII and NLR appear to be modest prognostic factors for anastomotic leakage and overall morbidity. Using an artificial neural network offers superior prognostic results in the preoperative risk assessment for overall morbidity and anastomotic leak rate
