Rural Industrial Complex(RIC) is considered as one of the most important sources of off-farm income in Korea. But RICs has many problems since it was beginning development. In 2008, RICs in Gyeongsangbuk-do are 56 place, and are 836 corportations in RICs. Employee is total 20,109 persons. Competitive power of RICs weak location condition, small business, lack of infrastructure, institute. The main focus of this paper is to derive policy suggestion for Gyeongsangbuk-do RICs. We investigate the operation status of Gyeongsangbuk-do RICs. It is necessary that RICs be promoted in light of revitalization program.

This paper proposes a dual heating method with direct inject water for saving service time of drip-coffee brew service. In case of hand-drip brew different to cold brew or espresso, it is problem that the service cost is high because of the service time. For solving the problem, there are many methods as like simple drip, drip using robot or specific drip. The water supply is usually used as water tank heating method. For direct inject water heating, we implemented hybrid heating system consisted of dual heater module included temperature sensor, inlet temperature sensor and flow detector and designed a bubble trap nozzle for a bubble problem of heating water. We experiment the proposed dual heating method using main heating for target temperature and complement heating for inlet temperature. The performance of a stable outflow temperature is evaluated by the experiment.
