Java Enterprise Edition Support in Search-Based JUnit Test Generation.

Many different techniques and tools for automated unit test generation target the Java programming languages due to its popularity. However, a lot of Java’s popularity is due to its usage to develop enterprise applications with frameworks such as Java Enterprise Edition (JEE) or Spring. These frameworks pose challenges to the automatic generation of JUnit tests. In particular, code units (“beans”) are handled by external web containers (e.g., WildFly and GlassFish). Without considering how web containers initialize these beans, automatically generated unit tests would not represent valid scenarios and would be of little use. For example, common issues of bean initialization are dependency injection, database connection, and JNDI bean lookup. In this paper, we extend the EvoSuite search-based JUnit test generation tool to provide initial support for JEE applications. Experiments on 247 classes (the JBoss EAP tutorial examples) reveal an increase in code coverage, and demonstrate that our techniques prevent the generation of useless tests (e.g., tests where dependencies are not injected)

La cultura del piano e il turismo relazionale integrato

L\u2019autore principale, alla data di pubblicazione del saggio, \ue8 responsabile del Laboratorio in Pianificazione Territoriale nel corso di Laurea in Pianificazione Territoriale Urbanistica e Ambientale dell\u2019Universit\ue0 di Palermo. Considerando il quadro delle modalit\ue0 di insegnamento della disciplina della pianificazione territoriale, la morfologia urbana e territoriale \ue8 la prevalente tipologia di approccio alle pratiche di trasformazione caratterizza le metodologie didattiche nelle scuole di architettura, mentre le teorie, da cui tali metodologie discendono, restano ben distinte e distanti dai saperi prossimi (e indispensabili) all\u2019urbanistica: ingegneria, scienze agrarie, geologiche, scienze della terra, scienze sociali, economiche e giuridiche. Il contributo al volume illustra i fondamenti metodologici e i risultati conseguiti dal laboratorio di pianificazione territoriale nel quadro della attualizzazione del pensiero di Giuseppe Samon\ue0 che considera centrale il principio dell'unit\ue0 Urbanistica-Architettura e che con l'altro concetto di \u2018citt\ue0 in estensione\u2019 (1980) fornisce le basi per declinare politiche e pratiche di turismo sostenibile nella chiave relazionale da integrare alle politiche di sviluppo locale

Clinical Reliability of Complete-Arch Fixed Prostheses Supported by Narrow-Diameter Implants to Support Complete-Arch Restorations

The aim of this study was to evaluate the clinical application of fixed screw-retained complete-arch rehabilitations supported by four narrow-diameter implants (NDIs). The records of patients treated with complete-arch prostheses screwed onto four NDIs treated with an immediate loading protocol between 2010 and 2020 with at least 1 year of follow-up after the positioning of the definitive restoration were reviewed. The implants were placed according to the final prosthetic design and were immediately loaded. The interim prostheses were replaced after the healing period by definitive acrylic resin titanium-supported prostheses. Patients were followed to evaluate treatment success, the implant survival rate (ISR), and the prosthetic survival rate (PSR). A total of 121 NDIs were positioned in 30 patients to restore 30 complete arches (18 maxilla and 12 mandible). One implant did not achieve osseointegration, resulting in an overall ISR of 99.2%. No prosthetic or implant failures occurred during the 1 to 11 years of follow-up. Three biological and four prosthetic complications occurred, resulting in a treatment rehabilitation survival of 94.1% and a PSR of 86.7%. Despite the limitations of the present retrospective study, such as the use of one single type of dental implant and patients treated in a single rehabilitation center, complete-arch rehabilitation with fixed prostheses supported by four NDIs seems to be a reliable treatment in the medium to long term

Oral health-related quality of life in partially edentulous patients before and after implant therapy: a 2-year longitudinal study

The aim of this study was to measure the Oral Health-Related Quality of Life (OHRQoL) before and after a prosthodontic implant therapy so to determine the physical and psychological impact of implant-supported fixed partial dentures (IFPD) rehabilitation among edentulous patients. Methods. 50 partially edentulous patients aged 40-70 years, treated with IFPD, completed the OHRQoL questionnaire before the implant surgery (Time 0) and 2 years after their whole implant-prosthetic rehabilitation (Time 1). The questionnaire was proposed in a short version of Oral Health Impact Profile (OHIP-14, range 0-56) and analyzed through the ‘additive method’. We evaluated statistical mean, standard deviation, median, variance and mode of all OHIP-14 domains and the statistical significance about oral changes at Time 0 and Time 1 using the Chi-square test (p-values 0.05). Patients with I and IV Kennedy’s class edentulism showed better improvement (p < 0.05). Preoperative and post-treatment assessments of OHRQoL exhibited significant differences. The IFPD treatment had a positive effect on the OHRQoL, which improved better in patients with I and IV Kennedy’s edentulous class

Atomic force microscopy of bacteria from periodontal subgingival biofilm: Preliminary study results

OBJECTIVE: Atomic force microscope (AFM) is a technology that allows analysis of the nanoscale morphology of bacteria within biofilm and provides details that may be better useful for understanding the role of bacterial interactions in the periodontal disease. MATERIAL AND METHODS: Five patients with periodontal ≥5 mm pockets diagnosed as generalized periodontitis and five patients with slight gingivitis were selected for the investigation. Bacteria biofilms were collected and morphologically investigated by AFM application. RESULTS: The investigation revealed how periodontitis bacteria are characterized by specific morphologic features of the cell wall. The major representative species of bacteria causing periodontal diseases have been reproduced by a three-dimensional reconstruction showing the bacteria surface details. CONCLUSIONS: The presence of complex glycocalyx structures, bacteriophage-like vesicles, spirochetes (classic and cystic morphology) and bacterial co-aggregation has been identified by the AFM analysis. The results suggest that AFM is a reliable technique for studying bacterial morphology and for examining microbial interactions in dental plaque
