manage, dispose of

経営する(けいえいする)	To manage a business. $$$

営む(いとなむ)	To manage a business. Usually used by older people. A more casual word than 経営.

管理(かんり)	Management or administration. Not like you run your own business (that’d be 経営する）, but like you are the manager of a department of a larger business.

処理(しょり)	To take care of a problem. To resolve a complaint. Unlike 経営　or 営む, 処理 is not a full-time job; more like something you do when an emergency happens.

処置(しょち)	Temporary, provisional management of a problem, until a lasting solution can be found:usually medical (i.e. stabilize the patient), but sometimes used about jury-rigging a machine.

処分(しょぶん)	Dispose of big, more-than-your-kitchen-garbage-can-type waste. Toxic waste. Giant dumpsters at a sports stadium. Old TV sets.
