최근 다양한 애플리케이션 도메인을 위한 IoT 솔루션이 개발되고 있으며, 농업분야에서도 IoT 기술을 적용하여 농작물 생산량은 늘리는 반면에 손실은 줄임으로써 농업 생산성을 향상시키기 위한 데이터기반 정밀농업 연구가 진행되고 있다. 이에 본 논문은 미기상 데이터를 수집하여 서리 및 병해충 등 농업예측서비스를 제공하기 위한 스마트팜 플랫폼을 제안하고자 한다. 제안된 플랫폼에서는 실시간으로 수집한 미기상 데이터를 기반으로 서리 및 병해충을 예측하여, 농민들에게 서리 가능성과 병해충 예보 서비스를 제공한다. 실험을 통해 확인한 결과, 미기상기반 예측 플랫폼은 지역기상기반 데이터를 이용한 서리예측보다 더 높은 정밀도(Precision)값을 보임을 알 수 있었다. 정확한 실험을 위하여 시스템 설치 현장에서 실제 관측한 병해충 예찰 데이터를 수집 중에 있다. 본 플랫폼을 활용하여 서리와 병해충 발생 예측정보를 사전에 효과적으로 제공함으로써, 농민들이 작물 피해 및 불필요한 농약 사용을 줄일 수 있도록 하는 정밀농업 서비스를 제공할 수 있을 것으로 기대된다.

There is a growing need to understand how local, farm household, and elementary units are responding to changes in agricultural conditions due to increased internal and external agrarian conditions and increased uncertainty in agricultural management due to increasing FTA and climate change. Therefore, we analyze dynamics of changes through more detailed and precise gathering of information related to agricultural products and DB, and by analyzing the satisfaction level of the first year panel survey by constructing a producer panel for utilization in agricultural research and policy. A total of 500 farmers in the producer panel who mainly grow rice, garlic, onion, strawberry, apple were collected through questionnaires. The actual analysis used data from a total of 393 farm households, including 82 farms of rice, 51 farms of apple, 100 farms of garlic, 88 farms of onion and 72 farmhouses of strawberry. The distribution by age was similar to the distribution of rural ages in Korea, with 2.8% under 30s, 17.6% in 40s, 32.4% in 50s, 37.5% in 60s and 9.7% in 70s. Panel happiness and rural life satisfaction were examined using the 7 - point Likert scale and the analysis method was one - way ANOVA. The results showed that the happiness of garlic and strawberry cultivator was significantly higher than that of rice and onion cultivator. However, the satisfaction of rural life did not show any difference among the cultivars. As a result of difference verification about Agricultural Outlook and Crop-specific Outlook after 5 years, there was no difference between the crops in terms of prospects for Korean agriculture after five years, but a survey of industrial prospects for crops after five years showed that the rice growers have a significantly negative outlook compared to garlic, onion and strawberry growers, and garlic and onion growers have a more positive outlook than rice and apple growers As a result of verifying whether there is a difference in ages between the agricultural prospects and the industrial prospects by crops after 5 years, there was no difference between the ages of prospects for Korean agriculture after 5 years, However, in the survey on industrial prospects by crops after 5 years, 40s were more positive than 60s.

약용작물은 재배 환경이나 재배 년수, 생육 시기, 부위별로 약리성분 함량에 차이가 많은데, 본 연구에서 해독, 소종, 소변불리, 간염, 황달 등의 치료에 효과가 있는 삼백초를 퇴비시용량과 재배방법을 달리하여 생육상황, 수량 및 유효성분 함량을 분석한 결과는 다음과 같다. 삼백초는 퇴비 시용량이 증가할수록 지상부 생체수량이 높았으며, 유효성분으로 quercetin, quercitrin 및 tannin 함량을 분석한 결과 퇴비 2,000kg/10a 처리시 가장 높았다. 예취 회수별 지상부 수량은 년 1회와 2회 수확간 차이가 없었으며, 유효성분 함량은 년 2회 수확하였을 때 7월 16일에 비해 10월 16일 수확시 함량이 높았다. 재배방법별로는 노지재배시 하우스재배에 비해 지상부 생체수량은 낮았지만 quercetin, quercitrin 및 tannin 함량은 높았다.

The public sector extension services in which governments of less developed countries (LDCs) have invested large sums often at the behest of donors are achieving uneven impact, often at unsustainable high costs. Further, the fundamental premise of public sector extension - that low-income farmers are unlikely to obtain technical information unless it is provided by government - increasingly requires re-examination. This paper reviews the pressures facing conventional agricultural extension, examines the prospects of recent approaches that are participatory, institutionally pluralistic and geared towards cost-sharing, and suggests ways forward for governments.

After late 1980s, new approach is needed for satisfying with people's various information needs and better quality of life on Korean extension service. The United States began modern extension service at first and has influenced many countries. Cooperative extension service has helped people practically by searching into people's problem and developing various channel to diffuse. Cooperative extension adopts changes in extension service environment and puts them to use. Based on the extension service in the United States, following recommendations were suggested; 1) carrying out extension service to meet the changing needs of people, 2) strengthening the extension function of agricultural Colleges, 3) review of cooperative agricultural research and extension, 4) developing programs and management, 5) accumulation agricultural information and utilizing them.

대추나무 빗자루병은 1950년대에 남한지역에 대발생하여 대추 재배지를 황폐화시킨 고위험 식물병이다. 최근 전국적으로 대추 재배면적이 크게 증가하고 있어 빗자루병 대발생 위험성을 사전에 파악하기 위한 기초자료를 얻고자 2017년과 2019년에 걸쳐 보은 지역의 대추 과원에서 병조사를 하였다. 또한, 빗자루병 조기 진단에 활용할 수 있는 다양한 병징을 찾아내고, 성보싸이클린수화제(OTC, 옥시테트라사이클린칼슘알킬트리메틸암모늄 수화제, 유효성분 17%)의 수간주사 방제효과 증진을 위한 연구를 수행하였다. 그 결과 현재까지 충북 보은 지역의 대추나무 빗자루병 발병률(이병주율)은 매우 낮았으나, 발생 지역과 발생 농가를 중심으로 점차 의미 있게 증가하고 있었다. OTC 방제시험 결과 처리 시기는 대추나무 생육 초기가 가장 효과적이었다. 그러나 발병이 심한 나무에서는 수간주사 후 당해 연도에도 같은 나무의 다른 건전한 가지에서 병징이 발현되었다. 6월에 1차 수간주사를 한 처리에서 2차 수간주사는 5개월 후보다 한 달 후에 하였을 때 방제효과가 더 좋았다. 이러한 결과는 조기 병징을 활용한 진단과 이를 근거로 한 조기 방제가 빗자루병 피해를 사전에 차단하고 병 방제효과를 높이는 데 매우 효과적일 수 있음을 시사한다.

The purpose of this study was to determine whether public services in rural areas performed the functions of public interest value that benefited all residents of rural areas. Therefore, the results were derived through spatial distribution and population characteristics analysis at the level of basic living service facilities. As a result, the status of spatial distribution in the Favorable and Vulnerable areas of rural villages and the status of population distribution in the vulnerable areas was analyzed for retail, child care and medical facilities. In the case of retail facilities, it was found that more than 80.0% of the country's farming villages were distributed in the favorable areas that could be reached within 15 minutes. In the case of child care facilities, 91.5% of the total number of favorable areas could be reached within 15 minutes, and the distribution of child care facilities nationwide was deemed proper. In the case of medical facilities, 90.8% or more villages could be reached within 15 minutes of travel time as a lawmaker, and in the case of hospitals and emergency medical services, 92.7% of hospitals and 68.2% of emergency medical services were analyzed as favorable areas. Through these results, the government intends to establish objective spatial data in rural areas to provide basic information on policy directions and contribute to planning.

Agro-Meteorological Information Service (AMIS) network has been established since 2001 by Rural Development Administration (RDA) in Korea, and has provided access to current and historical weather data with useful information for agricultural activities. AMIS network includes 158 automated weather stations located mostly in farm region, with planning to increase by 200 stations until 2017. Agrometeorological information is disseminated via the web site (http://weather.rda.go.kr) to growers, researchers, and extension service officials. Our services will give enhanced information from observation data (temperature, precipitation, etc.) to application information, such as drought index, agro-climatic map, and early warning service. AMIS network of RDA will help the implementation of an early warning service for weather risk management.
