We surveyed the sanitary conditions for 17 cold and frozen food storage warehouses in Korea, using the following 5 inspections items: "putting into warehouse (A)", "prevention of cross-contamination (B)", "storage management (C)", "temperature control (D)", and "management of records and documents (E)", We included 20 detailed items. The results of distribution for frequency by five major inspection items showed that "(E)" was the highest, the next "(D)", "(C)"; and "(B)" was the lowest. In the correlation of inspection scores between total scores, "(B)" and "(C)" were highly related to the total score, therefore, the higher score of "(B)" or "(C)", the higher for the total score. In details of inspection items, "the management of cross-contamination upon taking product out of the warehouse" had the lowest score with a mean, of $2.67{\pm}1.80$, and also ranked as first of the 20 items.

We are interaction refrigeration warehouse cold water pump system and photovoltaic generation system. At this time, a target pressure is able to control in spite of change of the pressure according to pump head and rate of flow of pump. Also, we carry out the vector control of BLDC motor with the maximum torque operation and a high reliability from territory of each operation speed. Therefore, in this paper, we conclude energy saving technique of refrigeration warehouse cold water pump system.

암모니아는 독성, 가연성 및 동 재질의 부식성 등의 단점은 있지만 CFC계 냉매가 개발되기 전에는 우수한 열역학 및 열전달 특성 때문에 냉매로서 가장 많이 사용되어져 왔다. 미국에서는 약120년, 일본에서는 약 80년 전부터 암모니아가 냉동 사이클에 사용되었고, 따라서 축적된 관련 기술 수준도 놀고 경험도 많은 편이다. 지금도 미국에서는 상업용 냉동기의 80% 정도가 암모니아를 냉매로 사용하고 있다. 우리나라도 냉동창고 냉동용으로는 암모니아 시스템이 널리 사용되고 있다.

As a result of this study, we reached the following conclusions. With appropriate setting of oil pressure and flow rate, it operated same rotation speed with existing cooler by electrical transmission. In initial operation, a temperature of a cold storage is lower rapidly. As an internal temperature of a cold storage is lower, a decreasing rate of temperature is lower. As a result of comparing the both type, the cooler of oil pressure type showed the following results. The decreasing rate of temperature was more faster and shorter operating time was more shorter than existing cooler of electric type. The actual case of a cold storage, the cooler of oil pressure type can prevent quality deterioration and decrease power consumption. As an internal temperature of a cold storage is lower, power consumption increased rapidly, the oil pressure type showed lower power consumption. COP of two of these types decreased continuously as the internal temperature of a cold storage being reach setting temperature, and that of oil pressure type showed higher amount about 25%. As a setting temperature is lower, the number of refrigerator's operating times are less and operating time is longer, so power consumption is increased in the maintenance of a cold storage's internal temperature, power consumption of hydraulic type showed lower amount about 21~25% in two of these types.

The construction of a "cold-chain cluster," which is a complex of cold-storage warehouses is emerging as an issue in the logistics industry. The Incheon Port Authority, in partnership with Korea Gas Corporation, is carrying out a project to build a cold-storage cluster using cold energy generated in the Songdo LNG receiving terminal. This study proposes a method of activating the cold-storage cluster using the CFPR methodology. An analysis of major factors showed that the most important factor was stability and profitability, which scored 0.281. For sub-factors, sustainable trade volume was the highest in importance, followed by rent level, the sustainability of LNG cold energy utilization technology, competition with general cold-storage warehouses, and exclusion of duplicate investments in facilities. For the future study, the evaluation of complex of cold-storage warehouses using major factors drawn out from this study is needed.

현재 사용되고 있는 냉동창고 재고관리 프로그램은 폐쇄 클라이언트 서버 환경에서 운용되고 있어 유지보수에 많은 비용과 인력이 소요될 뿐만 아니라 소비자인 화주에게 제공되는 서비스가 전무하며, 기본적인 수 발주를 위해서 팩스나 전화를 이용하므로 업무가 비효율적이며 오류와 부정확성 등의 문제가 발생하고 있다. 이러한 문제를 해결하기 위하여 본 논문에서는 다양한 모바일 운영체제에서 화주에게 서비스를 제공하는 모바일 웹앱을 설계하고 구현한다. 구현된 시스템에서 화주는 다양한 모바일기기를 이용하여 수 발주 업무, 재고량 조회 등의 서비스를 제공받아 업무를 처리할 수 있어 사용자만족도를 향상시켰다. 또한 모바일 운영체제에 독립적인 웹앱의 형태로 제공되어 사용자의 다양한 모바일 기기에서 운영될 수 있으며 실시간으로 유지보수를 제공할 수 있는 장점이 있다.
