It is widely known that labor costs are continuously and rapidly growing in terms of the raw cost of products in Korea. The increased labor costs are degrading the competitiveness of dairy industry sector as in the other major industrial fields. Furthermore, the number of dairy farms is constantly decreasing while that of dairy cattle is increasing. Thus, mechanized and/or automated stockbreeding management systems are crucially required to support professional stockbreeding management, as well as to enhance the productivity of the sector. Hence this paper develops an IIS (Integrated Information System) for dairy cattle stockbreeding management. IIS is composed of five application modules and associated utility programs. The five modules are individual stock management, milking management, feeding management, propagation management, and disease management. The utility programs are involved in stock farm accounting, and handy unloading of individual stock data into a personal data acquisition device. Compared with existing foreign products, the developed system takes advantages of various stock body measurement data such as body weight, body temperature, milk conductivity, milking amount, and the number of walking steps. All the measured data are transmitted into a programmable logic controller that monitors and controls measurement devices. The transmitted data are finally aggregated into an integrated database located in the main personal computer. The integrated data are analyzed and reformed in the five modules of IIS, then, used for providing farmers with various farm states and information through application module scenes. Hence, IIS keeps the each module work in a systematic and compatible manner, while supervising the whole stockbreeding management system.

Urine is a gift of God for the health of human being in proverbs of the Old Testament in Hindu. Urine therapy (UT) is not a mysterious folk remedy, it is doctor's examined prescription based on modern science and UT is recommended strongly with absolute confidence. It is effective and amazing to a number of incurables such as chronic fatigue, lingering, a cold, nose allergy, diabetes, high blood pressure, and gout. Also, UT is applied not only for human beings but also for animals, the latter including amazing effects for pigs and cows. The purpose of this manuscript is to help change the misunderstandings of urine and UT and to help reader realize it is one of the helpful alternative remedies.

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.

자동차산업의 발전과 함께 M2M(Machine-to-Machine)통신이 자동차 산업분야에서 많은 관심이 되고 있다. M2M은 기상, 환경, 물류, 국방, 농.축산 등에서 사용하기 시작하여 장비들이 자동으로 상황에 맞추어 통신을 하고 상황에 맞는 동작을 함으로써 운영해가는 시스템이다. 자동차에서도 차량내부 장치 간, 차대 차, 차와 교통시설물, 차와 주변의 환경 등에 적용되고 있다. 그러나 통신시스템의 특성상 전송구간에서 공격자의 공격에 대한 문제가 있으며 자동차의 운행, 제어계통 및 엔진제어 등에 공격자의 공격이 진행되면 안전에 심각한 문제가 발생하게 된다. 따라서 디바이스 간 보안통신에 대한 연구가 활발히 진행되고 있다. 본 논문에서는 차량의 디바이스간 안전한 통신을 위해 해시함수 및 수학적 복잡한 공식을 이용하여 프로토콜을 설계하였으며 프로토콜 정형검증 도구인 Casper/FDR을 이용하여 실험하였으며 제안한 프로토콜이 각종 공격에 안전하게 동작되며 실제 적용할 때 효과적임을 확인하였다.

Background: A model to assess the activity concentration of agricultural products and the public ingestion dose as result of a nuclear accident is necessarily required to manage the contaminated agricultural systems by the accident, or to estimate the effects of chronic exposure due to food ingestion at a Level 3 PSA. Materials and Methods: A dynamic compartment model, which is composed of three sub-modules, namely, an agricultural plant contamination assessment model, an animal product contamination assessment model, and an ingestion dose assessment model has been developed based on Korean farming characteristics such as the growth characteristics of rice and stockbreeding. Results and Discussion: The application study showed that the present model can predict well the characteristics of the activity concentration for agricultural products and ingestion dose depending on the deposition date. Conclusion: The present model is very useful to predict the radioactivity concentration of agricultural foodstuffs and public ingestion dose as consequence of a nuclear accident. Consequently, it is expected to be used effectively as a module for the ingestion dose calculation of the Korean agricultural contamination management system as well as the Level 3 PSA code, which is currently being developed.

최근 한 중 일 및 한 미 FTA가 발효되면 농축산업에 큰 타격을 줄 것으로 예상된다. 수입 자유화 이후 외국에서 생산된 농수축산물의 수입이 급증하고 있다. 그러나 질이 낮은 수입산이 국산으로 둔갑하는 일이 자주 발생하면서 농수축산물의 신뢰도 및 판로에 부정적인 영향을 미쳐왔다. 이에 생산이력 관리에 대한 필요성이 많이 요구되어지고 있다. 본 논문에서는 농산물의 유통이력은 물론 기존 시스템에서 제공하지 못한 생장환경이력정보와 시설재배에 따른 자동제어 및 저장고 모니터링 정보를 추가하여 RFID/USN 기반 농산물 이력관리시스템을 설계 및 구현하였다. 본 논문에서 설계 및 구현한 농산물 이력 관리시스템은 생장환경모니터 링과 이력관리로 구성된다. 첫째, 생장환경모니터 링은 USN을 활용하여 농산 물이 생산되는 재배지의 환경을 모니터링하고 저장고 및 재배시설의 자동제어기를 모니터링 한다. 생장환경모니터링 정보는 농산물의 생장환경에 대한 상세한 정보를 제공해 줄 수 있으며, 생산자가 영농일지를 자동으로 작성할 수 있도록 정보를 제공한다. 둘째, 이력관리는 농산물의 생산, 출하, 유통, 소비까지 모든 유통단계에서 발생된 이력정보를 소비자에게 제공할 수 있다. 본 논문에서 설계 및 구현한 RFID/USN 기반 농산물 이력관리시스템은 생산자에게 u-IT 농업을 제공하고, 소비자에게 농산물에 대한 신뢰도를 높여 줄 수 있다. 또한, 본 시스템을 적용하여 정부의 우수농산물관리제도와 위해 요소중점관리기준을 시행하는 데 기초자료를 제공할 수 있고, 국내 농산물의 고급화 및 선진화를 달성할 수 있다.

Objective: The purpose of the study is to evaluate appropriate weight for aged farmers in manually handling livestock feed in bags using ergonomic methods. Background: In the livestock industry in South Korea, despite the trend of aging of labor manpower, heavy items are still manually handled in many farms. In particular, among stockbreeding works, the handling of feed in bags weighing 25~30kg is reported as a cause of frequent injuries and musculoskeletal system diseases. However, studies on the standard for recommended weight allowed considering the physical characteristics of aged farmers older than 60 years with greatly decreased physical strength and muscle strength are insufficient. Method: To evaluate appropriate weight for handling of heavy livestock feed in bags, physical techniques for measuring recognized levels of physical work loads, the NLE (NIOSH lifting equation) a method that is an observation type technique, and an ergonomic modeling technique to predict compressive force imposed on L5/S1 were used. Subjects who participated in the experiment were organized into two groups of males/females with mean age exceeding 60 years, and lifting tasks were evaluated for nine weight levels. Results: Based on the results of psychophysical measurement, females showed a tendency of more drastic increases compared to males when weight was over 19kg. The results of estimation of regression models for the weight, 18.0 kg ($r^2=0.97$) and 15.3kg ($r^2=0.97$) were evaluated as stable load for males and females, respectively. In addition, both the observation type evaluation and ergonomic model evaluation showed stable loads in a range of 15~18kg. Conclusion: Given the results of the study, the weight of the feed in bags currently distributed to farms can become a cause of not only overexertion but also farm work related disasters such as musculoskeletal disorders and safety accidents. Providing livestock feed in bags weighing not more than 19kg for aged farmers is judged desirable, and managerial improvement for this matter is considered necessary. Application: The results of the present study can be utilized as useful data for institutional improvement of the weight of livestock feed in bags.
