The respondents were received environmental information. Habitat and gender did not make the difference in their realization.
Creating and Finding Efficiency Validation of Computer Assisted Instruction Focused on The Micro Structure of Iron
The purposes of the research were to create and find efficiency validation of computer assisted instruction focused on the micro structure of iron for the standard 80 / 80 and analyze the student learning achievement after using computer assisted instruction. The samples were the 20 first yearBachelor of Science in Technical Education students enrolled in Industrial Engineering Rajamangala University of Technology Phra Nakhon North Bangkok Campus. The Researcher experimented by using pretest and then using the computer assisted instruction focus on the micro structure of iron next the students did the posttest. After that the researcher calculated to find the computer assisted instruction efficiency and analyzed the students leaning achievement after studying. The result revealed that the computer assisted Instruction efficiency was efficient for standard 80 / 80. And after studying by using computer assisted instruction the students learning achievement increased significantly at 0.05.
The Detennination ofTotal Iron and Fluoride in Drinking Waters from Rajamangala University ofTechnology Phra Nakhon by Spectrophotometry
Total iron (Fe) and fluoride (F) in drinking water collected from Raj~angala University of Technology Phra Nakhon by using spectrophotometry method were detennined. During November 2007 and March 2008 30 drinking water samples were collected in 5 areas; Tewes Chotiwet Bangkok Commercial Chumporn Khet Udom Sale and North Bangkok. By spectrophotometric method Fe and F contained in samples were finally measured at 510 om and 570 om respectively.
Contamination of Endocrine Disrupting Compounds in Environment
Endocrine disrupting compounds (EDCs) are the substances that disrupt normal functions of hormones produced by endocrine glands affecting to system and organism functions under hormone control altering from nature conditions consequently cause adverse health effect in human and other living organisms. Most EDCs characteristics are lypophilic and persistence in environment. The hazardous EDCs produce from human activities contaminating in environment such as water air soil and food are produced etc.
