Software Defect Model Based on Similarity and Association Rule
Wan Jiang Han,He Yang Jiang,Tian Bo Lu,Xiao Yan Zhang,Weijian Li 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.7
In order to detect defects efficiently and improve the quality of products, this paper puts forward the concept about defect classification model and defect association model by a lot of defect data. The technology of similarity is applied to defect classification model, and the idea of Knowledge Discovery in Database is applied to defect association model. Defect classification model can analyze the defect efficiently and provides the basis of solving problems quickly while defect association model can be used to detect early and prevent problem, which can make effective improvements for testing and development. This paper summed up GUI defect model based on a large number of interface defects. The model is useful to improve the accuracy of forecast and be used for test planning and implementation through the practice of several projects.

Introduction: Smoking prevalence among the medical students is high in China. Therefore, understanding the smoking motivations of medical students is crucial for smoking control, but currently there are no scales questionnaires customized for probing the smoking motivations of medical students. This aim of study was to test and modify a questionnaire for investigating smoking motivations among medical students. Methods: A cross-sectional survey was conducted among 1,125 medical students at Xuzhou Medical College in China in 2012.The model fit and validity was assessed by confirmatory factor analysis (CFA) and the reliability was tested by single-item reliability, composite reliability, and item-total correlation. Results: The prevalence of smoking was 9.84 % among study population. In the modified scales, the global fit indices identified a CFI value of 0.96, TLI was 0.96, and the RMSEA was 0.063. CFA supported the two dimensional structure of the instrument. The average variance extracted ranged from 0.45 to 0.62. All single-item reliability scores were greater than 0.20, and the composite reliability ranged from 0.74 to 0.91. Conclusion: Modified scales could be the preliminary instrument used in evaluating the smoking motivations of medical students. However, it should be further assessed using other forms and methods of validity and reliability, additional motivations of smoking, and the survey of other medical colleges in China.

OsMADS1 plays crucial roles in the specification of floral organ identity and the determinacy of floral meristem in rice (Oryza sativa). Here we isolated a rice mutant cy15 with defective spikelets. Map-based cloning identified cy15 as a novel mutation in the C terminus of OsMADS1. Severe cy15 spikelets contained normal inner whorl organs but defective paleas, opposite to four abnormal whorls of Osmads1 flowers reported previously. In the cy15 spikelets, the size of the body was remarkably reduced in paleas, indicating a critical role of OsMADS1 in its differentiation. Moreover, the development of palea was impaired in the early stage of the cy15 spikelets. The sub-subcellular location of the mutant OsMADS1 was also affected in cy15. On the other hand, the truncated C terminus of the mutant OsMADS1 from cy15 still showed a significant transcriptional activator function. Meanwhile, though the mutant OsMADS1 retained intact M, I and K domains, its interactions with two highly homologous A-class proteins, OsMADS15 or OsMADS14, were weakened or abolished. Our data suggested that the C-terminal sequence of OsMADS1 might be required for maintaining normal morphology of spikelets in rice.

In modern diet of human being, the ω-6/ω-3ratio of dietary fatty acid was shifted much towards ω-6series. In this work, a fatty acid desaturase (FAD) gene lkfad15 was cloned and identified from oleaginous yeast Lipomyces kononenkoae. Function analysis results shown that LKFAD15 is a novel Δ12/Δ15 bifunctional FAD which could not only produce linoleic acid and α-linolenic acid use just oleic acid as substrate but also adjust the ω-6/ω-3 fatty acids ratio to the WHO recommended ratio. Phylogenetic analysis of LKFAD15 suggested it is a specific intermediate product of gene evolution derives from independent gene duplication events.
Anomalous magnetization jumps in granular Pb superconducting films

In granular superconductors, the grain boundaries are closely related to the vortex dynamics and the macroscopic superconducting properties. In our research, Pb films with different grain sizes were prepared by tuning the substrate temperature. With the grain size decreasing, Pb films are prone to feature the anomalous magnetization jumps in the M − T curves, while in the M − H curves flux avalanche happens. Both phenomena appear in the same region of the H − T phase diagram and thus are considered to have the same origin. The further theoretical analysis shows that with grain size decreasing the pinning mechanism evolves from a mixed δTc and δl pinning to the δl pinning mechanism. The results shed light on the study of pinning mechanism for granular superconductors and is beneficial to the potential application of manipulating vortex pinning by regulation of intrinsic defects.

SCY1-like 1-binding protein 1 (SCYL1BP1) is a newly identified transcriptional activator domain containing protein with many unknown biological functions. Recently emerging evidence has revealed that it is a novel regulator of the p53 pathway, which is very important for the development of human cancer. However, the effects of SCYL1BP1 on human lung squamous carcinoma cell biological behavior remain poorly understood. In this study, we present evidence that SCYL1BP1 can promote the degradation of MDM2 protein and further inhibit the G1/S transition of lung squamous carcinoma cell lines. Functional assays found that reintroduction of SCYL1BP1 into lung squamous carcinoma cell lines significantly inhibited cell proliferation, migration, invasion and tumor formation in nude mice, suggesting strong tumor suppressive function of SCYL1BP1 in lung squamous carcinoma. Taken together, our data suggest that the interaction of SCYL1BP1/MDM2 could accelerate MDM2 degradation, and may function as an important tumor suppressor in lung squamous carcinomas.
