Correlation between NASDAQ price, Corn and Gold(Corr=0.945)

Electric energy

2017/4/29. 80:20 principle: Electric energy is lost by where?

Electric energy is useful, but I think it's not used effectively.
In Japan, the loss of transportation electric energy is 5%.
(It's good, and how about sell that technology for foreign countries?)
How to use electric energy more effectively?
Decrease it, when devices are waiting, is good. 
Waiting time's electric energy. This is problem for loss by thought of 80:20 principle.

Cutting waiting time's electric energy is key technology. 
This technology includes software and hardware problems.

Cheaper work

2016/12/29. Cheaper works: Hard competition makes expensive work cheaper. In Japan, there are some people who thinks there are a lot of workers, and they are exchangeable easily.

None feedback

2016/12/29. None feedback from others in Japanese company Feedback is not always visible or sound , especially the fact of feedback is hidden by various suits. And in Japanese company, I often see the scene that ignorance to the people who did careless mistakes. Others don't say anything about the careless mistakes in front of the person, but in background, others speak ill of the person. This is none feedback. None feedback from others is very bad feedback, but in Japanese company, it is often. Why none feedback happens? In my experience, there are some reasons. When the person who made mistakes is upper than others, others want the person to fall out. When the person is equal level to others, others want the person not to promote. When the person is lower level, others want to make the person the targets for inner circle. I rethink that none feedback in company is bad signal for organization... None feedback happens when the company is bad statements!!!
