Message to Students

Why will your thoughts create your future?
You have been given the questions that can certainly be solved, solved them and your teachers have evaluated (scored) you by checking if your answers are right.  
Once you go into the real world, you are given issues or even if you find issues yourself, there is no guarantee that you can solve them.  You are expected to sort out issues in a way that you can solve (create questions), next try to solve them, show the validity of your answers by theories, experiments, simulations, and finally, test the achievements in the forms such as papers or products in the real world.  If it is not successful, you are supposed to repeat it again and again without giving up.  
You can impress the hearts of others once you put your thoughts (achievements made by try and error) and personality (character) into one of a series of these processes.  This will lead to the creation of a new future.
 
Wishing you to become wise engineers!
When we face an issue to be solved, the more complicatedly it is intertwined with various matters, the more often we are inclined to work on it based on the simple assumption that “its solution should be such and such.”  When we try to solve the issue with this stance, we might make a big mistake.  Because we are likely to keep our eyes on the matters only leading to or supplementing the “predetermined conclusion” and thus, we cannot pay attention to the matters suggesting underlying essential problems behind it and what is wrong with the predetermined conclusion.  
Such a mistake is made when we insinuated ourselves into strong opinions neglecting minor disagreeing opinions.  It is not too much to say that it happens far too frequently at an individual level to a large organization level.  We can avoid making a big mistake by always working on any matters with a humble attitude wondering “if there is anything wrong with the supposed conclusion or the hypothesis” and paying attention to and caring about any trifles and opinions.  
We wish you to become wise engineers who will not make such a mistake
 
Wishing you to become wise leaders!
When a person sits in the seat of power, as long as he or she is not wicked, everyone starts with intention to commit to an organization in good faith.  Many of those in power, however, will become high-handed and lose trust later on.  What is the reason for this?  
Once one takes the seat in power, he or she sets up a committee with his or her friends who know each other well.  Generally, deliberation is made without disclosing it to the outside until they reach a conclusion.  Those friends who know each other well are actually a sort of crooks.  Those friends have certain bias more or less.  Thus, their bias will be amplified as deliberation goes on, and when they proceed without noticing it, their deliberation will greatly lose touch with the thoughts of the general public.  If they push forward to implement the “best measure” they considered for the organization without recognizing it, the general public will rebel against them, and after all, this will lead to the point that “those who have power are high-handed and untrustworthy.”  In order to prevent this, it is necessary to “share information” in a wider range, promote the “disclosure of information (freedom of speech)” including that of opposite opinions, form a “rough consensus (a rough agreement)” while testing it at a small scale, and expand the range of its application gradually after confirming that it is successful.
You will be in a position to lead an organization in the future if you do your best in the real world after graduation.  We wish you to become a wise leader who will never be given such words as “Power is high-handed and untrustworthy.”
