Effects of AL-MIAP-based Learning Management to Promote Digital Intelligence for Undergraduate

<p>This paper has two main aims: the first is to study pre- and post- leaning achievement utilizing AL MIAP to promote copyright digital intelligence for Suan Suan Sunandha Rajabhat University undergraduate students; and the three is to investigate the appropriateness of leaning management adopting an AL MIAP leaning model to promote the students’ digital intelligence. An AL MIAP learning model was utilized in the processes to promote five digital intelligence skills, i.e. respecting copyright, prevention, checking before sharing, threat awareness and using safely. Fifty-eight Suan Sunandha Rajabhat University undergraduate students in the three year enrolled in the introduction to digital economy course and were selected in a sample group. The tools were: Kahoot!, Google Forms, content network chart, pre- and post-test, digital media copyright test and the AL MIAP learning model. Percentage, mean, S.D, and T-test were applied in the research. The study revealed that the post-learning achievement was better that the pre-learning achievement with statistical significance at 0.01; the students gained total scores of 17.06, which was 7.16 points higher than the pre-learning scores, signifying that their digital intelligence skills were better. As for AL MIAP leaning model, it revealed that this model was appropriate at the highest level. </p>

Optimization Algorithms of PERT Network Diagram in Software Project Management System

The PERT network diagram optimization and the node layout optimization were studied in order to solve the difficulty of using manual methods to generate the PERT network chart in large-scale software project management. The new methods of optimization the node of PERT was proposed based on ant colony optimization algorithm (ACO) and genetic algorithms (GAs). The high adaptability and population optimization technology of GAs are discussed and also the ACO is introduced to realize the nodes layout global adjustment. In the end, calculation and simulation results show that the methods proposed can make the number of nodes of PERT network diagram generated automatically minimum. Meanwhile, it can make the layout of nodes of PERT network diagram more efficient and effective, so as to effectively solve the large-scale software project assessment problem.

Project management in building industry management

The article deals with contents of the project management on general level first. It mentions the most widespread project management standards, which have historically developed in global scale, their parts and objectives. Further, it describes position of the building industry in national economy, its specific features distinguishing it from the other industrial production, contents of the building industry management and project management of structures. The importance of the role of project manager is documented by characteristics of construction projects, their course, contents of sub-phases, and individual types of managing activities. Attention is devoted to project planning – determination of realization costs, necessary resources, sequence and time course of individual works. The most frequently used graphic methods of schedule presentation – Gantt chart, network chart and frequency bar chart are applied on examples of constructions. These charts can be focused in time sequence on individual types of resources – workforce, finance, materials, energies, and machinery. In conclusion, necessity to manage the project management procedures is emphasized as a part of skills of a construction engineer in the role of preparation manager or construction project realization manager.

Molecular genetic diversity and origin of Chinese domestic duck breeds

The 667 bp control region of mitochondrial DNA from 8 representative domestic duck breeds in China, which were all native preserved duck breeds, and a mallard (6 Anas zonorhyncha individuals) were sequenced. The genetic polymorphism and the origin of the 8 domestic ducks were analysed. The result showed that the haplotype diversity (Hd) and average nucleotide diversity (Pi) were 0.67136 and 0.19 %, respectively. Hd and Pi of Youxian Sheldrake were the highest in the 8 domestic duck breeds. Kimura-2 parameter genetic distance between the breeds ranged from 0.00056 to 0.00414. The NJ phylogenetic tree and reduced median-joining network chart were constructed by the total 38 haplotypes and 96 sequences, which included 12 sequences of Anas platyrhynchos from GenBank, 6 sequences of Anas zonorhyncha from GenBank and 78 sequences of this study (72 domestic ducks and 6 Anas zonorhyncha). The maternal origin of the 8 domestic ducks all originated from Anas platyrhynchos.
