In the preceding paper, the conditions to completely kill 108 colony-forming unit(CFU) of Escherichia coli were 5 min in 2.5 ppm of sodium hypochrolite. The concentrations to kill coliform bacteria or other bacteria lived in scouring sponges themselves were proved to be 20 times higher than the preceding result. One reason is that some fats or residues from foods and kitchen detergents existed in the sponge were thought to decrease the effect of the disinfectant.
The author designed a system that can utilize MindMap without adding any software to a PC. Practicing using MindMap was then done in a classroom setting as a learning activity. Learners made mind map according to a learning process which consisted of "indicating a learning theme", "clarifying an outline by a bottom-up approach", and "clarifying details by a top-down approach". As a result, the ability of learners to plan designs and organize their thoughts significantly improved after completing the activity.
Isoflavones in soybeans and L-citrulline are known to have beneficial actions on cardiovascular disorders. In this study, it was demonstrated that genistein and daidzein significantly inhibit high glucose-induced proliferation of smooth muscle cells from mouse thoracic aortas. However, L-citrulline showed no effect on the proliferation of the smooth muscle cells. These results suggest that isoflavones may play a role in the prevention of vascular thickening.
In 2005, the author created a system in which high school students can look at news flash Web pages to find out whether or not they passed their entrance examination. The system is still in use today. Access to the system is granted by authenticating examinees by having them enter their date of birth. Only the examinees themselves have access to the system and they can find out the results of their entrance examination test right away. It is a convenient system that can improve security. In this paper, the details of the passing news flash system will be discussed.
In 2005, the author created a system in which high school students can look at news flash Web pages to find out whether or not they passed their entrance examination. The system is still in used today. It has not been clear how often people have been using it, so the author conducted a survey to look the issue and the results of the survey will be discussed in this paper.
