The Research of Data Mining Based on Application Data Pool
Minjie,Bian,Jue,Gao,JiePin,Xu,Honghao,Gao 보안공학연구지원센터 2014 International Journal of u- and e- Service, Scienc Vol.7 No.5
Today, people use various kinds of information technology applications to deal with applications in our daily life, which generates lots of information. However,most of the informationis just stored in many Distributed Heterogeneous Databases (DHDs) as log records, instead of being used abundantly and effectively. In this paper, we mainly discusses about how to use these data in useful ways by Data Mining (DM). Relative to thetraditional Data Mining based on Data Warehouse (WD),we propose a definition named Application Data Pool (ADP)replacing WD in this paper. And we design a KnowledgeDiscovery in Databases (KDD) model with ADP to use these data more efficiently. At last we use an application in Shanghai University ID Card designed with the ADP to prove the effectiveness and feasibility in KDD.

Risk Factors of Hepatocellular Carcinoma - Current Status and Perspectives
Gao,,Jing,Xie,,Li,Yang,,Wan-Shui,Zhang,,Wei,Gao,,Shan,Wang,,Jing,Xiang,,Yong-Bing Asian Pacific Organization for Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.3
Hepatocellular carcinoma is a common disorder worldwide which ranks 5th and 7th most common cancer among men and women. In recent years, different incidence trends have been observed in various regions, but the reasons are not completely understood. However, due to the great public efforts in HCC prevention and alternation of lifestyle, the roles of some well documented risk factors played in hepatocarcinogenesis might have changed. This paper summarizes both the environmental and host related risk factors of hepatocellular carcinoma including well established risk factors such as hepatitis virus infection, aflatoxin and alcohol, as well as possible risk factors such as coffee drinking and other dietary agents.

Knockdown of Bcl-3 Inhibits Cell Growth and Induces DNA Damage in HTLV-1-infected Cells)
Gao,,Cai,Wang,,Xia,Chen,,Lin,Wang,,Jin-Heng,Gao,,Zhi-Tao,Wang,,Hui Asian Pacific Organization for Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.1
Oncoprotein Bcl-3 is perceived as an unusual member of $I{\kappa}B$ family since it can both stimulate and suppress NF-${\kappa}B$ activation. Aberrant Bcl-3 results in increased cell proliferation and survival, suggesting a contribution to malignant potential and elevated levels of Bcl-3 have been observed in many HTLV-1-infected T cell lines and ATL cells. To investigate the specific roles of Bcl-3 in HTLV-1-infected cells, we knocked down Bcl-3 expression using shRNA and then examined the consequences with regard to DNA damage and cell proliferation, as well as NF-${\kappa}B$ activation. The HTLV-1 encoded protein Tax promotes Bcl-3 expression and nuclear translocation. In HTLV-1-infected cells, Bcl-3 knockdown obviously induced DNA damage. Cell growth and NF-${\kappa}B$ activation were reduced in HTLV-1-infected or Tax positive cells when Bcl-3 expression was decreased. Together, our results revealed positive roles of Bcl-3 in DNA stabilization, growth and NF-${\kappa}B$ activation in HTLV-1-infected cells.

An Optimization Algorithm with Novel Flexible Grid: Applications to Parameter Decision in LS-SVM
Gao,,Weishang,Shao,,Cheng,Gao,,Qin Korean Institute of Information Scientists and Eng 2015 Journal of Computing Science and Engineering Vol.9 No.2
Genetic algorithm (GA) and particle swarm optimization (PSO) are two excellent approaches to multimodal optimization problems. However, slow convergence or premature convergence readily occurs because of inappropriate and inflexible evolution. In this paper, a novel optimization algorithm with a flexible grid optimization (FGO) is suggested to provide adaptive trade-off between exploration and exploitation according to the specific objective function. Meanwhile, a uniform agents array with adaptive scale is distributed on the gird to speed up the calculation. In addition, a dominance centroid and a fitness center are proposed to efficiently determine the potential guides when the population size varies dynamically. Two types of subregion division strategies are designed to enhance evolutionary diversity and convergence, respectively. By examining the performance on four benchmark functions, FGO is found to be competitive with or even superior to several other popular algorithms in terms of both effectiveness and efficiency, tending to reach the global optimum earlier. Moreover, FGO is evaluated by applying it to a parameter decision in a least squares support vector machine (LS-SVM) to verify its practical competence.

A recent randomized and double-blind placebo-controlled clinical study bas indicated that Ganoderma lucidum polysaccharides (GLP) decrease blood glucose in patients with type II diabetes. The aim of this study was to investigate the effect of the GLP extract in alloxan-induced diabetic rats. Oral administration of GLP at 0.25, 0.5 and 1.0 g/kg for 4 weeks resulted in a reduction of blood glucose levels by 12.5, 18.7 and 33.7% respectively, while glibenclamide treatment brought the hyperglycemic value down to normal. The hyperglycemic effect was supported by a significant decrease in glycosylated haemoglobin and increased plasma insulin levels (p<0.01) in a dose- and time-dependent manner. This study showed that GLP has similar hypoglycemic effects as glibenclamide in alloxan-induced diabetic rats.

The effect of different tumbling marination treatments (control group, CG; conventional static marination, SM; vacuum continuous tumbling marination, CT; vacuum intermittent tumbling marination, IT) on the quality characteristics of prepared pork chops was investigated under simulated commercial conditions. The CT treatment increased (p<0.05) the pH value, $b^*$ value, product yield, tenderness, overall flavor, sensory juiciness and overall acceptability in comparison to other treatments for prepared boneless pork chops. The CT treatment decreased (p<0.05) cooking loss, shear force value, hardness, gumminess and chewiness compared with other treatments. In addition, CT treatment effectively improved springiness and sensory color more than other treatments. However, IT treatment achieved the numerically highest (p<0.05) $L^*$ and $a^*$ values. These results suggested that CT treatment obtained the best quality characteristics of prepared pork chops and should be adopted as the optimal commercial processing method for this prepared boneless pork chops.
