Definition
a.    Philosophy:àK3 
Specifically, thinking and efforts to keep the unity and perfectness of worker and human both mentally and physicaly in general, artwork, and cultures of society toward social welfare.
b.    Knowledge:àK3

Knowledge and its application in order to prevent accident probably caused by work.
c.    Practical:àK3
The effort of protection so that workers are always in safe and health during the work, work safely and efficiently.
K3 Destination
a.    Grant physical and mental perfectness of workers, and their artworks and cultures.
b.    Prevent and reduce accident and disease caused by work.
c.    Grant:
1) Each worker and others in workplace get protection.
2) Each production source can be used safely and efficiently.
3) Production process run well.
Preparation and Work Safety during PC Assembly
1.    Screw driver, pliers, AVO meter (if any), soldering tool, tin, tape, wire binder, and notebook. Both soldering tool and AVO meter are rarely used when component used is still good condition.
2.    Curent measurement and voltage of electricity is only conducted when the component used is a used component which no view good or not.
3.    AVO meter should not be used when motherboard is still in good condition because the point of measurement has not been known. Recklesness can cause fatal damage.
4.    When you use new component, you do not need to perform curent and voltage measurement by AVO meter. AVOmeter may be needed to recognize electricity voltage in home electricity network.
5.    When you recognize, look at the power supply of computer (in the case) whether it is already set to voltage scale appropriate to surrounding voltage or not. If the power suply is automatic, you will not need to be worried. If it is semi automatic, you probably need to set the scale position of 24 voltage to voltage position appropriate to surrounding.
