When the important structures or components of agricultural machinery are designed, the full-filed methods of stress analysis can provide enough information in order to obtain lighter weight and prevent failure. The photoelasticity has been applicated to solve many practical engineering problems. The coating method provides full-field information, enabling the engineers to determine the complete distribution of surface strains and directly highlighting severely strained areas, especially for the welded frames of agricultural machinery. A combined method of model and prototype for strain analysis of excavator has been successfully applied to improve design. A measuring and recording system controlled by micro-computer and application software for dynamic event was studied. It can be widely used in structural failure analysis under cyclical loading . Typical application concerned stress field of crack tip and failure analysis of some mechanical structures are introduced are in roduced briefly in this paper.

Generally, because individual agricultural product possesses its own distinctive characteristics and shows different characteristics at each stage of the agricultural supply chain, it is necessary to develop a proper enterprise architecture for managing information system. In this paper, we propose an enterprise architecture based on RFID/USN technology that can be used as a reference enterprise architecture for u-IT application in the agriculture sectors, which is called the u-Farm enterprise architecture with taking heterogeneous characteristics of agricultural products into account for. In addition, we also developed the RFID/USN middleware platform as a core infrastructure technology. Fo evaluation of the performance of the proposed u-Farm architecture and the RFID/USN middleware platform, the field-trial evaluation at the apple Agricultural Processing Center (APC) has been executed and the results shows that the proposed architecture and platform perform well in terms of information integration over the whole SCM process from the farming stage to delivering statge to the customers. It is expected that the proposed u-Farm enterprise architecture can be utilized as a standard information architecture, and the RFID/USN middleware platform can be a infrastructure platform for future u-IT based information technology applications and services in the agricultural environment.

우리가 살아가는데 중요하고 빼놓을 수 없는 요소 중의 하나인 음식(食), 요즘 이 음식(食)재료 중의 하나인 농산물을 구매할 때, 소비자가 해당 농산물을 신뢰하기가 어렵다. 그 이유는, 해당 농산물에 대한 생산 정보를 쉽게 얻을 수 없고, 만약 얻을 수 있더라도, 고작 생산 국가 정도의 정보만이 표기되어 있을 뿐, 생산자, 생산지, 잔류 농약, 그리고 토질의 상태 등, 믿을 수 있는 정보를 얻을 수 없기 때문이다. 이에 따라 소비자들은 해당 농산물을 구매하려 할 때, 신뢰할 수 있는 정보를 제공해주길 원한다. 이에 본 논문에서는 RFID(Radio-Frequency IDentification) 리더기를 이용해 해당 제품에 부착된 RFID 태그를 읽어, 획득한 인증번호를 웹서버에 전송하여 생산 정보 및 안전성 검사 정보를 얻고, 이를 소비자에게 제공하여 해당 농산물에 대하여 신뢰를 줄 수 있는 농산물 생산이력정보 제공 시스템을 구현하였다.

전국의 학교 급식 및 군 급식 등 대규모 농축수산물의 물류가 이루어지고 있으나, 안심 농축수산물에 대한 물류정보가 거짓표시 되어 안전한 식품공급에 사회적인 이슈가 되고 있다. 외국산 저 품질 축산물을 국내산 고품질 축산물로 둔갑시키고, 일반 농산물을 친환경 농산물로 속이고, 오염된 채소류를 신선한 채소류로 속여서 학교 및 집단급식소에 식자재로 납품하고 있다. 본 논문에서는 부정 농축수산물의 물류정보에 대한 보안 방법과 부정 농축수산물 피해로 인한 법적인 책임소재 증거자료로 e-Discovery시스템을 적용하여, 책임 소재와 피해 보상에 대한 연구가 필요하다.

Drought is a disaster that causes prolonged and wide scale damage. Recently, the severity and frequency of drought occurrences, and drought damage have been increased significantly due to climate change. As a result, a quantitative study of drought factors is needed to better understand and prevent future droughts. In the case of agricultural drought, several existing studies examine the economic damage caused by droughts and their causes, but these studies are not well suited to estimating crop-oriented agricultural drought damage and the factors that absolutely affect agricultural drought. This study determines which factors most affect agricultural drought. It examines meteorological factors and those related to agricultural water supplied by irrigation facilities. Rice paddy production per unit area is lower than the average from the last two years where agricultural drought occurred. We compare the relative frequency of agricultural drought impacts with irrigation facilities, effective reservoir storage, the number of water supply facilities, and the meteorological drought index such as Standardized Precipitation Index (SPI). To identify factors that affect agricultural drought, we correlate rice paddy production anomalies with irrigation water supply for the past two years. There was a high positive correlation between rice paddy production and irrigation water usage, and there was a low or moderate negative correlation between rice paddy production anomalies compared to the average of the past two years and SPI. As a result, agricultural water supply by irrigation facilities was judged to be more influential than meteorological factors in rice paddy production. This study is expected to help local governments establish policies related to agricultural drought response.

Due to the rise of Information & Communication Technology (ICT) adoption in many fields, it is necessary to diagnose the informatization situations of corporations in agriculture and give suggestions for improvement. For this goal, surveys were designed and conducted to understand the current informatization situations of agriculture corporations in Korea. The survey covers the plan for utilizing information technology, the establishment of infrastructure for information technology, IT application status, and its effect on their performance. The specific focus of our research is to segment the corporations by their type of industries and their level of sales and give differentiated managerial implications for each segment. This is because the type of informatization and information technology assistance they need highly depends on their industry type and sales level. Based on descriptive statistics and regression analyses, tailored managerial and polic.

Evaluation in both an art and a science. The art of evaluation involves working with the management to agree upon purpose and users of results, creating design and gathering information that are appropriate for a specific situation and a particular policy making context. The value of evaluating extension p개grams has received a lot of attentions recently, and many extension educations see evaluation as an integral part of their work. The science of evaluation involves determining standards and developing indicatiors, selecting methods appropriate to gather information in a systematic way, analyzing information to assist in determining the value of the program in an objective manner. First, extension specialists have to consider relative merits about methods of gathering evaluation data. Selection of method should be influenced by the type of information desired, time availability, and cost of using the method. Second, good evaluations involve stakeholders at all stages including planning, implementation, and utilization of results. Third, far from being an "add-on ," evaluation begins with the initial planning of an educational program. Fourth, it is important for extension specialists that although evaluation is valuable and essential in any effective program, one of the biggest mistakes of extension program evaluators in to promise results that cannot possibly solve all the problems of project.

지표대기 모형 BATS를 한반도 사례에 적용하여 한반도 전지역에 대한 농업기상정보를 산출하였다. 자료입력에서 출력까지의 전 과정이 일괄적으로 수행될 수 있도록 모형의 입출력 및 전후처리 과정을 수정하였으며 이를 토대로 간단한 조작만으로 쉽게 농업기상요소들을 생산해 낼 수 있는 농업기상정보 자동산출시스템을 개발하였다. 모형의 결과와 관측값을 비교해 본 결과 지면온도와 뿌리대층 온도는 약 2.0$^{\circ}$C, 윗토양층 온도는 약 2.6$^{\circ}$C의 오차를 보이는 것으로 나타났다.
