The ADAM and ADAMTS families, also called adamalysins belong to an important group of extracellular matrix proteins. The ADAMs family belong to both the transmembrane and secreted proteins, while ADAMTS family only contains secreted forms. Adamalysins play an important role in the cell phenotype regulation via their activities in signaling pathways, cell adhesion and migration. The human proteome contains 21 ADAM, and 19 ADAMTS proteins, which are involved in extracellular matrix remodeling, shedding of various substrates such as: adhesion ligands, growth factors, their receptors and diverse cytokines. Recent studies provide evidence that adamalysins play a crucial role in colorectal cancer (CRC) etiopathogenesis. It seems possible that adamalysins might be used as CRC prediction markers or potential pharmaceutical targets.

Data mining is a process of discovering useful patterns or information from large amount of data. Decision tree is one of the data mining algorithms that can be used for both classification and prediction and has been widely used for various applications because of its flexibility and interpretability. Decision trees for classification generally generate a number of rules that belong to one of the predefined category and some rules may belong to the same category. In this case, it is necessary to determine the significance of each rule so as to provide the priority of the rule with users. The purpose of this paper is to propose a rule selection method in classification tree models that accommodate the umber of observation, accuracy, and effectiveness in each rule. Our experiments demonstrate that the proposed method produce better performance compared to other existing rule selection methods.

Although a table of descent is a mandatory primary source for studying medical persons, but most of those who practiced medicine were not but of step families. Because members of step families are not usually recorded accurately, preceeding studies did not put much emphasis on them. But as more researchers study biography and the number of studies done on historical figures are increasing tremendously, its value as a source has increased as well. In order to research a person, obtaining background information is a priority, which includes to what family they belong to, to what specific branch of the family they belong to, etc. Whether or not the person has ever worked with a public institution is important as well.

We reviewed the available drosophilid literature and listed any drosophilid species with Vietnamese records. Vietnamese drosophilid flies belong to two subfamilies. In this paper, we provided a taxonomic checklist of 68 nominal species. However, this checklist is based on information of diverse literature, and we have not confirmed identification of each species. In total, the number of drosophilid species in Vietnam amounted to 68 species belong to 16 genera. Drosophilinae consists of 12 genera and 51 species, while Steganinae includes four genera and 17 species. This checklist will be the fundamental base for comprehensive taxonomic research of drosophilid fauna in Vietnam.

The purpose of this thesis is to offer basic data for clothing design which is intended to apply appropriate shape and capacity to clothes. The following are the analyzed results of an investigation which was conducted to characterize the upper half of the female body of 193 women whose ages are 18 to 25, taking part in this investigation. According to the results of analyzing young women's bust, I came to find a large individual difference of the wide varying factor numbers at the items of the side feature, the body stance, and the dart quantity. For the analysis of the female's upper body, 11 factors are used. The are as follows: Factor 1. width of the bust Factor 2. height of the bust and length of the arm Factor 3. side thickness of the bust and the upside type Factor 4. length of the bust on the front Factor 5. length of the bust on the back Factor 6. salient ratio of the breast Factor 7. width of the neck. the armhole, and measurement of the droop Factor 8. length of the shoulder Factor 9. flat ratio of the bust Factor 10. inclination of the shoulder factor 11. form of the back The shape of young women's upper bodies can be divided into four groups. The character ization of each group are as follows : Group 1 . 28.5% of the women who take part in this investigation belong to Group 1 These women have the shortest body, with a longer length of the front than the back and more thickness on the front than the back. Group 2. 21.1% of the women who take part in this investigation belong to this group. They show a longer length of the back and more thickness of the back than the front. In addition, this group is bent forward. Group 3. This group is the mast common type, showing the shortest and thickest character. 37.8% of the women who take part in this investigation have this bust character Group 4. 12.4% of the women belong to Group 4. They possess the highest and fattest character, skewing smaller necks, armholes, and waists than the other groups. This group also shows the drooping shoulders.

Ecological network can solve the ecological problems such as habitat cutting and fragmentation that are resulted from urbanization. Recently, rooftop biotope construction has been appeared as a usefull method for ecological networking in urban area. The objective of this study is to seek the possibility of rooftop greening introduction as well as to select target species for rooftop greening construction from the urban ecological network point of view. In order to select target species, we monitored two adjacent rooftop greening sites, where we found 22 species of birds and insects and 33 species of plants. We set criteria to select target species through documents research, and gave marks species according to the criteria with the help of specialists. We divided the target species into 5 groups on the basis of the 12 selecting criteria. In those two monitored rooftop greening sites, we did not find any species belong to group A, which is the best target species, but we found species belong to the other groups. Orthetrum albistylum, Sympetrum dawinianum belong to group B, which is the priority target species, 7 species besides Passer montanus, Coccinella axyridis, Agrionidae to group C, which is the possible target species, 6 species besides Atractomorpha lata to group D, which is the potential target species, and the others were found to be inadequate to the target species. We found Orthetrum albistylum, Sympetrum dawi-nianum to be the best appropriate target species in the two sites. According to the result of this study, the method of ecological network construction from the dra-gonfly habitat network point of view through the construction of rooftop habitat is ideal for Orthetrum albistylum, and Sympetrum dawinianum. For successful urban ecological network construction, selection criteria and construction techniqes & methods for rooftop habitat should be developed through future research.
