摘要： Software readability and comprehension are important factors in software maintenance. There is a large body of research on software measurement, but the actual factors that make software easier to read or easier to comprehend are not well understood. In the present study, we investigate the role of method chains and code comments in software readability and comprehension. Our analysis comprises data from 104 students with varying programming experience. Readability and comprehension were measured by perceived readability, reading time and performance on a simple cloze test. Regarding perceived readability, our results show statistically significant differences between comment variants, but not between method chain variants. Regarding comprehension, there are no significant differences between method chain or comment variants. Student groups with low and high experience, respectively, show significant differences in perceived readability and performance on the cloze tests. Our results do not show any significant relationships between perceived readability and the other measures taken in the present study. Perceived readability might therefore be insufficient as the sole measure of software readability or comprehension. We also did not find any statistically significant relationships between size and perceived readability, reading time and comprehension.

Novel Confocal-Laser-Scanning-Microscopy and conventional measures investigating eroded dentine following dentifrice dab-on and brushing abrasion
摘要： Objectives: To validate novel non-contacting Confocal-Laser-Scanning-Microscopy (CLSM) methodology with conventional Contacting Pro?lometry (CP) measures investigating brushing or dab-on of stannous-?uoride dentifrice on early aggressive dentine erosion. Methods: 75 polished human dentine samples were prepared and eroded in agitated 6% citric acid then randomly allocated into 5 intervention groups; arti?cial saliva control (1); controlled use of a pressure sensitive counter-rotating oscillatory powered toothbrush with sodium-?uoride NaF (2) or stannous-?uoride SnF2 (3), and dab-on application of NaF (4) or SnF2 (5). Samples underwent three cycles of intervention and 2-min agitated 6 % citric acid challenges. CLSM images were taken and 3D reconstructions produced of step height using a developed software algorithm. In addition, 20 % samples were randomised and pro?led using CP to measure step height and surface roughness. Vickers's diamond micro-hardness testing was carried out on all samples. Results: Comparing CLSM and CP; Pearson correlation was 0.77 and Intra-class correlation 0.81 (p ? 0.01). There were no signi?cant statistical differences in step height between groups using both CLSM and CP. From baseline, SnF2 brushing (3) increased micro-hardness more than control (1) (p ? 0.03), NaF (4) and SnF2 dab-on (5) (p (cid:2) 0.001), and increased surface roughness more than control (p ? 0.02), NaF brushing (2) and NaF dab-on (4) (p (cid:2) 0.017). Dab-on of SnF2 (5) produced rougher surfaces than control (1) (p ? 0.014) and reduced hardness compared with NaF brushing (p ? 0.04). Conclusions: Good agreement and correlation exists between CLSM and CP measures in dentine. There were no signi?cant differences in surface loss after interventions between groups. Compared with control, SnF2 application increased dentine surface roughness and SnF2 controlled powered brushing application increased dentine hardness, likely caused by exposure of uneroded dentine. Clinical signi?cance: Isosurfaces produced using CLSM can be used to represent dentine step height loss. They show good correlation and agreement with conventional CP measures, following early aggressive erosion-abrasion cycles of dentine. The CLSM and computer algorithm therefore provides an accurate, standalone and non-contacting three-dimensional measurement of early dentine wear. Stannous-?uoride brushing, and dab-on application offer no bene?ts following early aggressive erosion in dentine. To reduce dentine wear, limiting erosive challenges and avoiding brushing post-erosion is advised.
