This paper provides a review of the progress in America, Europe, Japan and china withnumerous standardizations and investigations for the protection and repair of hydraulic concrete structures.These researches include detection technologies, evaluation methods, applications of newconcrete reinforcing and repair materials. This paper identifies the significant progress made by theInternational Commission on Large Dams(ICOLD).At the same time, some specific investigations are carried out on the ageing of hydraulic concrete structures in china. On this basis, the detection, assessment and remediation analysis of hydraulic concrete structures are summed up, and someadvice is put forward to the next stage of work.

In a study of the properties of a Ta-Au metallization system for thin film technology application, the interdiffusion between Ta(bcc)-Au, βTa-Au and Ta2M-Au films was studied. Considered here is a discussion of the use of the transmission electron microscope(TEM) in the identification of phases formed and characterization of the film microstructures before and after annealing.The films were deposited by sputtering onto silicon wafers with 5000 Å of thermally grown oxide. The film thicknesses were 2000 Å of Ta and 2000 Å of Au. Samples for TEM observation were prepared by ultrasonically cutting 3mm disks from the wafers. The disks were first chemically etched from the silicon side using a HNO3 :HF(19:5) solution followed by ion milling to perforation of the Au side.

Entering the XXI century and especially in the period of the industrial revolution has entered the era of IT with the knowledge economy in the trend of globalization. The 4.0 mankind development of ICT, especially the Internet has had a strong impact and make changes to all activities profound social life of every country in the world. Through surveys in six high School, interviewed 85 managers and teachers on the status of the management of information technology application in teaching, author of the article used the SWOT method to distribute surface strength, weaknesses, opportunities and challenges from which to export 7 management measures consistent with reality. 7 measures have been conducting trials and the results showed that 07 measures of necessary and feasible.

The integration of Information and Communications Technology (ICT) in classrooms has been a challenge for the educational systems that aim to cope with the needs and the demands of the 21st century. The TPACK framework represents the knowledge needed by teachers bringing together content knowledge, technological knowledge and pedagogical knowledge with the aim of integrating ICTs into teaching-learning processes. The aim of this study is to determine the primary science teachers’ perceptions of technological pedagogical content knowledge (TPACK) addressing teachers’ perceptions of the affordances of technology application in instruction. A total of 133 prımary science teachers in Malaysia were surveyed (Female= 67, Male= 66). Data were collected through “Technological Pedagogical and Content Knowledge” (TPACK) scale. The questionnaire consisted of 47 questions about TPACK and is based on the survey instrument developed by Schmidt et al. (2009). TPACK involving the seven factors of technological knowledge (TK), pedagogical knowledge (PK), content knowledge (CK), technological content knowledge (TCK), technological pedagogical knowledge (TPK), pedagogical content knowledge (PCK), as well as synthesized knowledge of technology, pedagogy, and content (TPC). The findings indicate that primary science teachers perceive higher self-confidence in pedagogical knowledge in general. Further, no differences between science teachers’ perceptions according to thier gender, while there are diferences between the teachers perceptions of PK, CK, and PCK accordıng to their age
