  • 이 연구는 자동수위계가 설치된 378개소 농업용저수지에 대하여 웹기반 실시간 농촌홍수관리시스템을 구축하기 위하여 이루어졌다. 농촌홍수관리시스템은 한국농어촌공사의 농촌용수종합정보시스템(Rural Agricultural Water Resource Information System, RAWRIS)과 연계 운영되는 시스템으로서 RAWRIS의 통합 데이터베이스에 구축 관리되는 일강우자료, 시강우자료, 자동수위측정자료를 실시간으로 수신하여 연계 활용하는 시스템이다. 이들 자료를 이용하여 강우사상이 발생되는 시점을 기준으로 해당 강우사상기간동안의 매시간 홍수분석을 수행함으로서 해당 저수지로의 홍수유입량의 변화양상을 파악할 수 있는 계산결과를 제공함과 동시에 수위증가와 계산방류량으로 인한 저수지 상 하류의 홍수위험도를 등급화 하여 화면에 표출함으로서 광역적인 홍수현황을 파악할 수 있도록 구성하였다. 더불어 기상청 기상특보와 예보자료로부터 해당저수지유역에 발생가능하다고 생각되는 강우량을 저수지 관리자가 직접 입력하여 분석할 수 있는 기능을 통해 댐 운영에 참고 될 수 있는 정보를 제공할 수 있게 하였다.

  • 농촌지역의 복잡한 물관리 체계를 정립하고 효율적인 용수관리를 위해서는 하천과 농업용 수리시설물의 연계를 통한 관개시스템의 네트워크 모델링이 필요하다. 본 연구에서는 수자원분야의 지리정보데이터를 다루도록 개발된 ArcHydro Model을 한국농촌공사에서 개발한 농촌용수수요공급량산정시스템 (AWDS: Agricultural Water Demand & Supply Estimation System)과 연계하여 안성천유역내에 위치하는 "안고"농촌용수구역을 대상으로 네트워크 모델링을 구현하였다. ArcHydro Model을 이용하여 유역내의 24개의 저수지, 18개의 양수장, 28개의 취입보 등 총 70개의 수리시설물의 공간객체와 하천망간의 연관성을 부여하여 상호간의 위상관계를 가지도록 네트워크 모델링을 하였다. 또한 농촌용수수요공급량산정시스템에 대한 텍스트 결과를 ArcHydro Model을 통하여 수리시설물의 공간위치를 가시적으로 표현함으로서 특정 시설물의 위치파악이 쉽고, 순차적인 물수지의 체계를 이해하기 쉽도록 ArcGIS의 시스템에 메뉴를 추가하여 개발하였다.

  • This study perceived that there are limits to prompt and accurate monitoring when an accident occurs and the correct information of egg production stage, such as the date of spawning, cleaning, and refrigerating cannot be identified, since eggshell codes using barcode only show numbers identifying a city and province and the name of producers. To fix this problem, this study partially suggested the RFID (Radio Frequency Identification) technology and IoT-based Connected System. The proposed system in this study shares data with related agencies as the system of agricultural and livestock product information runs as the main server, and the database information of the proposed system is provided by farmhouses, distributors, and sellers. Through various media such as a webpage or mobile application built to provide the relevant information, customers can search and obtain information about agricultural and livestock products they want. Since the information on an entire process is open to the public, information ranging from simple to clear, additional ones such as hazardous elements can be viewed.

  • A total of 20 mulberry varieties preserved in Korea were typed for eight polymorphic microsatellite loci. We obtained 6 to 15 alleles per locus with an average value of 10.6, per-locus observed heterozygosity ranging from 0.35 to 1.00, and per-locus polymorphic information content (PIC) ranging from 0.61 to 0.87, indicating that most loci are highly variable. Phylogenetic analysis using the eight microsatellite loci was sufficiently suitable for classifying 20 mulberry varieties preserved in Korea. A total of 160 variety-specific apomorphic alleles were obtained from eight loci discriminated 20 mulberry varieties. These variety-specific alleles from this analysis are expected to be useful for the discrimination of other mulberry varieties. Furthermore, a substantial number of homozygote loci, represented by 60 among 180 alleles in eight loci were found. These results collectively suggest that these microsatellite locus primers are potentially crucial molecular markers for the eventual classification of mulberry varieties that are preserved as hundreds in Korea.

  • This study was conducted to develop software which provides automatic site-specific field data acquisition, data processing, data mapping and management for precision agriculture. The developed software supports acquisition and processing of both digital and analog data streams. The architecture was object-oriented and each component in the architecture was developed as a separate class. In precision agriculture research, the laborious task of manual ground-truth data collection will be avoided using the developed software. In addition, gathering high-density data eliminates the need for interpolation of values for un-sampled areas. This software shows good potential for expansion and compatibility for variable-rate-application (VRA). The FIM (Field Information Management) computer program provides the user with an easy-to-follow process for field information management for precision agriculture.

  • A Web-based information system from the Korea Agricultural Water Use Laboratory AWUL, has been developed to provide with regional water management information and guidance for the operations of irrigation reservoirs through the World Wide Web(WWW). Twenty-six reservoirs are selected as the reference reservoirs for regional water management , and the real-time operation guide may be issued the grwoing seasons. The information available from the system includes the wether forecasting , drought analyses, and reservoir operation data for those reference sites. For a specific reservoir, the manager may access the system to obtain the water requriement, irrigation secheduling , and reservoir operations that fit best to the irrigation district.

  • Market integration and prices in pulse crops like black gram play an important role in determining the production decisions of the farmers and diversification towards high value nutritious crops. In this context, the present study explores extent of market integration and price transmission in selected major black gram markets in Andhra Pradesh using Johansen co-integration, Vector Error Correction Model and Granger causality test. The study used monthly prices data of black gram (Rs/quintal) sourced from selected markets of Srikakulam, Krishna and Kurnool spanning January, 1990 to December, 2019. The results of the study strongly buttressed the existence of co-integration and interdependence of selected black gram markets in Andhra Pradesh. However, the speed of adjustment of the prices found to be moderate in Krishna market and quite weaker in Srikakulam market and thereby prices correct a small percentage of the disequilibrium in these markets with the greatest percentage by the external and internal forces. So, it necessitates the need for future research, to investigate the influence of external and internal factors such as market infrastructure, Government policy and self-sufficient production, product characteristics and utilization towards market integration. As there exists only unidirectional causality from Krishna to Kurnool and from Krishna to Srikakulam markets, it calls for strengthening the information technology for flow of market information regularly to help the farmers for increasing their income.
