Garlics were cutted various size and shape and dried on heat air drier and smashed it and stocked after wrapped with polyethylene bags. The change of composition and quality were identified as follows. 1. Six and seven hours drying the garlics which was cutted 2 mm thickness, under the temperature at 60°C, the moisture content in garlic was obtained 8-9%. 2. The yield of dried garlics Eusung and Urlung Do varieties were 35-36% and the yield of Eusung variety was prodominated 1-2% than Urlung Do variety. 3. There were no browning reaction occurred while drying garlics, causing by many kinds of enzymes and oxygen. 4. It could preserved one year, dried garlics with wrapped polyethylene without lost its quality. 5. More than 35% of garlics could prevent its loss while drying garlics which storaged with polyethylene bag, compare with hang drying method. 6. No different taste found in the Kimchi which were made by fresh garlics.

독립형 풍력발전 시스템용 양방향 DC/DC 컨버터 및 단상 인버터 전력제어 방법
이상건,김성안,박대근,변상인,조윤현 대한전기학회 2012 대한전기학회 학술대회 논문집 Vol.2012 No.4
본 논문에서는 독립형 풍력발전 시스템의 전력제어에 사용되는 양방향 DC/DC 컨버터의 모드절환을 포함한 전압-전류제어 방법과 DC/AC 인버터의 부하특성을 고려한 전력제어 방법을 제안한다. 양방향 DC/DC 컨버터는 발전전력과 부하용량의 차에 해당하는 컨버터 요구 전력과 DC-Link 전압의 오차를 통해 DC-Link 전압을 제어하고, SRF(synchronous reference frame) 전력제어방법을 적용하여 단상 DC/AC 인버터를 위상의 지연이나 정상상태 오차가 없도록 제어한다. 제안된 전력제어 방법을 PSIM을 통해 구현하고, 시뮬레이션을 통해 검증하였다.

This study attempted to segment restaurant outlet image and identify differences among customer satisfaction. Whereas brand image has been explored widely in restaurant marketing literature, this study addresses the importance of outlet image as a competitive marketing strategy.Four factors were identified for restaurant outlet image as sanitation, personal service, atmosphere, and taste & price. A cluster analysis based on the identified four underlying dimensions of the outlet image resulted in three clusters of guests (highly-perceived group, mid-perceived group, low-perceived group). The highly perceived group were found to differ from the other two groups on the level of customer satisfaction. In particular, the highly perceived group showed higher level of satisfaction. And the managerial implications of these results for outlet image are examined.
