The structure of the Hanwoo (Korean Native Cattle) Industry remains very weak and vulnerable to the WTO/IMF system. Considering that the majority of cattle farmers are small sized, and that marketing systems are outdated and inefficient, rapid expansion of lower priced beef imports by WTO system and rapid increasing of production costs by IMF system would lead to the deprivation of a regular source of farm income and threaten the stability of rural life. Accordingly, the Hanwoo industry should be expanded in accordance with progress in the implementation of (1) programs for the structural adjustment and (2) measures to compensate for the loss. Efforts for lowering major production factor costs needs to continue, In order to increase the supply of calves at low cost, the programs of collective cow-calf farms should be expanded, thereby reducing the cost of calf purchase, which constitutes the largest share of Hanwoo production cost. Also, feedlot operations should be encouraged for small herd farms in order to achieve a substantial saving in beef production costs by integrated operations from calf production to cattle fattening. A substantial saving would also be made by collective purchase and distribution of various inputs through the cooperatives' channels. Extension services should be strengthened for cattle farm management, cattle care and feeding, prevention of cattle disease, etc. In order to minimize cash outlays for commercial mixed feeds, utilization of far by-products as feeds should be enhanced and production of forage crops productive of resources, such as land and rural labor, during the farm o(f-season, needs to be encouraged. Also, technological development for enhancing the nutritional value of farm by-products should be encouraged. Measures for successful segregation of the Hanwoo beef market should be implemented, thereby enhancing incentive for quality beef producers and protecting consumers willing to pay higher price for quality beef. For development of the Hanwoo industry, a considerable time frame would be required in order for (1) small livestock farmers to make a successful adjustment by staying in the enterprise and achieving increased price efficiency (2) livestock farmers to acquire know-how for producing quality Hanwoo beef, (3) the ongoing Government policy of enhancing price-quality competitiveness, and for improving the quality Hanwoo beef marketing to take root. (4) consumers to increase their ability to distinguish meat quality, and others.

The agricultural environment is changing and becoming more advanced due to the influence of the 4th Industrial Revolution. From the basic plan of Rural Informatics to the current level of 2nd generation smart farms aimed at improving productivity using Big data, cloud network and more IoT technology. We are continuing to provide support and research and development. However, many problems remain to be solved in order to supply and settle smart farms in Korea. The purpose of this study is to provide a method of collecting and sharing data on farming environment and to help improve the income and productivity of farmers based on collected data. In the case of hog farm, the multiple sensors for environmental data like temperature, humidity and gases and the network environment for connecting the internet were established. The environment sensor was made using the ESP8266 Node MCU board as micro-controller, DHT22 sensor for temperature and humidity, and MQ series sensors for various gases in the hog pens. The network sensor was applied experimentally for one month and the environmental data of the hog farm was stored on a web database. This study is expected to raise the importance of collecting and managing the agricultural and environmental data, for the next generation farmers to understand the smart farm more easily and to try it by themselves.

Objectives: This study aimed to identify PM₁₀ mass concentration levels and conduct peak identification during five tasks in agricultural works. Methods: We investigated five agricultural tasks in 12 farms, which were harvesting, plowing, sowing, planting, and decapitation. All samples were measured by using the portable aerosol spectrometer(PAS 1.108) and the aerosol monitor(SidePak AM520). The collected data were compared with the national PM₁₀ concentrations. They were calculated to descriptive statistics, independent t-test, or ANOVA, and the peak identification on time series graph. Results: The ten investigated farms showed no significant difference with the national PM₁₀ concentrations, but the two greenhouses(AM, 143.31, 85.16 ㎍/m³) showed significant difference(p<0.05). As a result of the peak identification, the harvesting tasks showed repeated peak occurrence with the background concentration level of about 50 ㎍/m³. For plowing and sowing tasks, the peak occurred intermittently when the working was conducted near the sampling sites. Among the five tasks, the arithmetic mean of the harvesting task was 138.84±294.71 ㎍/m³, which was significantly higher than the other tasks(p<0.05). In addition, the case of using a tractor was higher than the case of not using the tractor(p<0.05), and the driver's seat showed the highest concentration(AM, 95.81 ㎍/m³). Conclusions: Works in greenhouses might have exposure to PM₁₀, while outdoor works is similar to general atmospheric PM₁₀ concentration levels. However, there is a possibility of intermittent exposure to high concentrations of PM₁₀ depending on the characteristics of agricultural tasks.

해상풍력발전 단지를 개발함에 있어 전력수급과 경제성 논리에만 초점이 맞춰짐으로써 여러 가지 환경적 문제들이 발생하고 있으며, 이에 따른 지역사회의 갈등이 유발되고 있는 실정이다. 특히 최근에 국내 해역의 풍황과 해황 조건 등을 중심으로 해상풍력에 대한 입지와 개발량에 대한 연구가 이루어져 왔으나, 해양환경 및 해양생태계에 미치는 영향에 대한 연구는 매우 부족하다. 유럽의 해상풍력발전 선진국에서는 개발 사업에 뒤따르는 환경 모니터링이 활발히 진행되고 있는 데 비해, 국내에서는 해상풍력을 설치하고 운영할 때에 발생할 수 있는 환경적 영향에 관한 모니터링 자료가 전무하다. 따라서 본 연구에서는 국외 해상풍력의 모니터링 사례 및 참고문헌의 사례를 분석함으로써 공사 시와 운영 시의 환경적 영향과 국내 해역에 적합한 환경영향평가 단계에서의 가이드라인을 제시하였다. 이에 따라 궁극적으로는 해상풍력개발에 따른 환경영향을 최소화하고 환경영향평가의 행정절차에 소요되는 협의기간을 단축시키는 데에 목적이 있다.

본 연구에서는 한국의 유기농업의 문제점을 파악하고 앞으로의 개선 및 발전방향을 제시하기 위해 서구와 한국의 유기농업 발달과정, 한국의 유기농산들 인증제도와 생산의 특성, 전국의 유기농산물 생산의 지역적 분포 및 특성에 대해 살펴보았다. 우리나라의 유기농업은 1970년대에 형성된 유기농산물 생산 연구 소비단체를 중심으로 자생적으로 시작되었으나 국제적 표준에 맞는 '친환경농산물인증제'를 수립하여 제도적으로 수용한 것은 2001년 7월부터이다. 2002년 현재, 친환경농산물의 과반수가 저농약재배로 인증을 받았고, 화학비료와 유기합성농약을 전혀 사용하지 않은 유기재배농산물은 전체 농산물 가운데 0.2%로 극히 적은 비율을 점유한다. 작물별로는 채소류의 유기재배비율이 가장 높고, 과실류는 재배방법상의 어려움으로 아직 대부분이 저농약재배로 생산된다. 유기농가의 평균 경작규모는 0.88ha로 관행농가의 1.39ha에 비해 상대적으로 적은 규모이다. 유기농가 집중지역은 충청북도 괴산군과 같이 자생적인 유기농산물 생산 연구 소비단체들이 처음 결성된 지역이며, 경기도의 팔당상수원 보호구역과 같이 환경오염을 발생시키는 활동이 일찍부터 제한되었고 대도시 소비시장에 인접한 지역이다. 유기농업이 지역에 뿌리내리는데는 작부체계관리, 기술개발 및 이전, 마케팅, 사후서비스 등에서 유기농산물 생산 연구 소비단체들의 역할이 주요한 요인으로 작용한 것으로 보인다. 개방농정으로 농업의 고사 위기가 심화되고 있는 시점에서 지방자치단체들은 친환경농업을 지역특화산업화하기 위한 계획을 세우고 있는데, 친환경농업운동은 지역별 환경보전운동과 함께 추진되는 것이 바람직하다.

국제사회는 글로벌 기후위기 극복을 위해 2050년까지 탄소중립(Net Zero)을 목표로 다양한 탈탄소 에너지원 개발을 지속하고 있다. 우리 정부에서도 '재생에너지 3020' 정책을 수립하고 태양광이나 풍력을 이용한 에너지 개발계획을 추진함에 따라 해상 풍력발전단지와 같이 연안해역에서 기존에는 볼 수 없었던 대규모 해양개발사업이 추진되고 있다. 해양시설물은 선박의 입장에서 볼 때는 항행 장애물의 일종이며, 해양시설물 설치에 따라 좁아진 수역에서 선박 간 충돌사고 발생 또는 선박과 해양시설물의 접촉사고 발생시 환경오염 및 인명피해 등의 발생이 우려된다. 이에 국내외의 해상풍력발전단지 개발계획을 살펴보고 풍력단지에서 선박의 안전한 통항을 보장하기 위한 제도적 장치가 완비되어 있는지 분석하였으며, 해외의 입법 사례와 국내 법규를 비교하여 법적 사각지대를 해소하기 위한 새로운 법령안을 제안함으로써 대한민국의 관할해역에서 해양시설물의 안전한 운영과 선박의 안전한 통항을 기대하였다.

This study was performed to identify the prevalence of cryptosporidiosis and giardiasis in diarrhea feces of Korean native calves raised in Gimje, Jeollabuk-do, with a rapid diagnostic kit. The prevalence of both diseases were classified according to the age of calf, season of sampling period, and sampled farm where diarrheic calf is commonly observed. In diarrhea feces of 431 calves, cryptosporidiosis had a high incidence rate between 1 and 3 weeks of age, whereas giardiasis showed a high incidence between 4 and 6 weeks of age. It is thought that the incidence of protozoan diseases is markedly influenced by the calf's postnatal age. Regarding with the sampling season, the prevalence of cryptosporidiosis and giardiasis in calves was significantly higher in spring and summer than in autumn and winter (P<0.05). Among the sampled farms where both diseases are commonly observed, cryptosporidiosis was more frequently detected than giardiasis in calves. Particularly, in farms where cryptosporidiosis is common, it tends to be a disease that is difficult to eradicate as it occurs continuously throughout the year. Hygiene management such as regular cleaning and disinfection of the livestock and the surrounding environments is considered necessary to reduce and prevent damage from these protozoal diseases.

This study was carried out to investigate the status and development direction of horse riding industry for rural development of Korea. Library research and field survey were conducted to collect relevant data such as number of horse and size of horse farms, facilities for horse riding and educational institutions for youths and farmers and the results obtained were as follows : Only a few institutions among high schools, colleges and universities were observed to deliver horse riding programs. For farmers, no equestrian specialist was available in agricultural extension offices. Horse meat is consumed mostly in Jeju Island in Korea. Relevant institutions should be also strengthened including formal and nonformal education for horse riding and much more schools and universities should adopt horse riding program for the training of youths and farmers. Considering the obesity problem, the nutritional composition of horse meat is better than those of pork or beef, so promotion of horse meat consumption also should be strengthened.

In 1996, Thailand's participation in the Pacific Rim as a part of NASA's Mission to Planet Earth (MTPE) Program, was titled 'AIRSAR Thailand Project'. In this project the Department of Land Development utilized Topographic SAR (TOPSAR) which had multi-frequencies: C band, L band, and P band with multi-polarization: HH, VV, and HV as well as C band VV DEM. Satellite data such as LANDSAT TM was also utilized for optimal use. Results of AIRSAR image processing including data fusion among difference wavelength bands and polarization revealed the quality of AIRSAR that best suit for detection of agricultural land uses. The HH-L band AIRSAR was proven to be useful to distinguish among crop types when combined with appropriate data. The HH, VV, and HV-P band enhanced surface characteristics of swamp forest and wetland. In addition, TOPSAR has its great advantage for identification of salt farms and shrimp ponds.
