The insecticidal activities of 27 different commercial products with environmentally friendly organic material (EFOM) against Scotinophara lurida, a major rice pest, were evaluated in the laboratory using spraying methods on plants and insects. Seven plant-derived organic farming materials (EFOM-8, -10, -12, -13, -19, -20, and -26) with high insecticidal effects when sprayed directly on the insect’s body rather than on the plant were selected. In the indoor rice pot test, all 7 EFOMs showed an insecticidal rate of over 73.3% under irrigated conditions. Notably, EFOM-13 and EFOM-20 demonstrated much higher insecticidal rates, ranging from 1.5 to 1.8 times, in irrigated conditions compared to drained conditions. In the semi-paddy field test, EFOM-10 (80% garlic extract), EFOM- 13 (62% neem extract), and EFOM-26 (70% sophora extract+28% ethyl alcohol+2% pyrethrum extract) exhibited a higher control value of 88.9% in the irrigated paddy on the 7th day, surpassing the control values in the drained paddy by 1.4 to 1.9 times. The control value in the irrigated rice paddy field sprayed with EFOM-10 reached 86.2% on the 7th day, which was 1.4 times higher than 61.9% in the drained paddy. Taken together, the findings suggest that direct contact of the insect’s body with sufficient amounts of spray solution and the maintenance of paddy irrigation can enhance the controlling effect of EFOMs. These findings will be valuable in developing an optimal S. luridacontrol strategy for application in rice paddy fields in the near future.

The blockage rate for three kinds of nets commonly used in agricultural facilities was assessed by using the image acquisition and its relevant processing. By using both empirical relations presented by Idel’chik and Richards and Robinson, and the blockage rate obtained from the image processing, the pressure drop through the nets was predicted and also compared with wind tunnel experiment results. The results of the study showed that the blockage rate of the net was discriminated according to such factors as the magnitude of nets, the existence of inside threads, the thickness and number of threads. In addition, the blockage rate for the incident angle of 0° when the wind blew at the front had the range of 0.22－0.29 (0.22－0.32 when considering whole incident angles from 0° to 45° by 15°). For the nets with the blockage rate of about 30% or below, the prediction by the empirical relations of by Idel’chik and Richards and Robinson showed a little higher pressure drop overall than that of the wind tunnel test, but the use of the empirical relations and the blockage rate could be thought of as providing effectively meaningful guidelines for the safe design of agricultural facilities including nets because the wind tunnel test has been tedious and expensive. Further research and potential application on the prediction technique of the pressure drop, regarding both a subtle deformation by the wind and manufacturing methods with regard to the level of knots and the existence of inside threads, needs to be done for the nets with higher blockage rate.

This study was conducted to evaluate Korean rice cultivars to search any suitable varieties for the northern region of the Korean Peninsula (North Korea). A total of 92 rice varieties which included 74 bred cultivars from South Korea, 13 collections from North Korea and five local cultivars from China, were involved in the evaluating trials for their performance. Stability at three sites inthe northeastern areas of China, which are located in the northern border areas of North Korea, for three years from 2017 to 2019. The ecologically well-adapted rice varieties were selected at each trial site during the first year and employed again as the materials for the subsequent yield trials. A total of six varieties with relatively better performing and stability were selected through the subsequent trials at three sites for three years: Unkwang, Daejin and Taebaek at Dandong region; Hanseol and Taebong at Longjin region; Taebong and Namweon at Hunchun region, respectively. Dandong is located in the southeast parts of Liaoning, which has similar climatic characteristics to the west coastalregion of North Korea. Longjin is located in the middle-east parts of Jilin, which has also similar climatic characteristics to the northern inland region of North Korea. Hunchun is located in the northeastern parts of Jilin, which has presumably similar climatic characteristics to the northern part of the eastern coastal region of North Korea. Unkwang is characterized by its early maturity, with the heading at the 2nd of August, and reveals a yield potential of 7.11 T/ha with resistance to the blast (BL) and the bacterial leaf blade (BLB) diseases. It is predicted to be suitable for the northern area of the Suyang mountain region and the central inland region of North Korea. Daejin has asemi-early maturity heading around the 6th of August and yields of 6.06 T/ha with resistance to BL, BLB, and stripe virus (SV) diseases. Daejin will be adaptable to the northern area of Suyang mountain region. Taebaek is medium maturing variety of Indica/Japonica type. It is heading at the 14thof August with good ripening at maturity, and has yield potential of 6.84 T/ha with resistance to BL, BLB and SV diseases. It will be adaptable to the southern area of Suyang mountain region. Hanseol is early maturing, heading on the 3rd of August, and yields 6.44 T/ha with the short stature and cold tolerance (CT). It will be adaptable to the northern inland and mountainous regions of North Korea. Taebong is semi-early maturingwith the heading at the 6th of August and has a yield potential of 6.96 T/ha with cold tolerane and blast resistance. Taebong was also outstanding in theHunchun region, indicating a more or less wide adaptability in cold areas. It is expected to be adaptable to the northern inland region of North Korea as well as the northern part of the eastern coastal region. Namweon is a medium-maturing variety with aheading date of August 10, and a yield potential of 4.76 T/ha with cold tolerance and resistance to rice neck blast disease. It is expected to be adaptable to the northern part of the eastern coastal region.

This study examines and proposes standardization approaches to address the heterogeneous issues of metadata in drone imagery within the agricultural sector. Image metadata comes in various formats depending on different camera manufacturers, with most utilizing EXIF and XMP. The metadata of cameras used in fixed-wing and rotary-wing platforms, along with the metadata requirements in image alignment software, were analyzed for sensors like DJI XT2, MicaSense RedEdge-M, and Sentera Double4K. In the agricultural domain, multispectral imagery is crucial for vegetation analysis, making the provision of such imagery essential. Based on Pix4D SW, a comparative analysis of metadata attributes was performed, and necessary elements were compiled and presented as a proposed standardization (draft) in the form of tag information.

This study identifies the commercialization success factors that can be an important indicator for the transfer and commercialization of national R&D results in the agricultural sector. Unlike other industries, the agricultural sector has a non-systematically scaled and processed industrial structure, and R&D is led by government rather than the private sector. Although the quantitative performance of national agricultural R&D, especially the number of patents and publications, has increased rapidly with the quantitative expansion of the government R&D budget, the technology commercialization of the results of agricultural R&D has been accompanied by difficulties for SMEs. Therefore, this study summarized the success factors for commercialization of state-owned technologies presented in previous studies, and based on them, analysed the success factors for commercialization specific to the agricultural sector. It also conducted a questionnaire survey using Delphi and focus group interviews (FGI) with experts from academia, research and industry, and a survey of agricultural companies to derive success factors for commercialization in the agricultural sector using logistic regression analysis. As a result, five indicators with positive correlation and three indicators with negative correlation within technology characteristics, suppliers, adopters, policy and market factors were finally derived as key factors for agricultural commercialization. In the future, it is expected that independent factor analysis of the food and seed sectors, which have independent industry characteristics from the agricultural sector, will be needed.

본 연구는 등유를 사용하는 농업용 난방기에서 배출되는 가 스를 포집하고, 농업용 난방기의 사용 연식에 따른 이산화탄 소의 배출농도를 파악하고자 수행되었다. 선형 회귀분석의 결과로 농업용 난방기의 연식에 따른 이산화탄소의 배출량은 R2 = 0.84로 y = 26.99x+721.98의 식을 따른다고 나타났다. 농업용 난방기의 사용 연식에 따라 세 그룹으로 분류하여 분 산분석을 수행하였다. 분산분석을 수행한 결과, 분석을 위해 설정한 유의확률 0.05보다 작은 2.1961×10-13으로 나타났으 며 이는 적어도 한 그룹에서 차이가 나타난다는 것을 의미한 다. 본 연구에서는 농업용 난방기의 기본적인 배출농도의 차 이를 분석하고자 기기의 제작사와 상관없이 농업용 난방기의 기기 연식만을 고려하여 배출가스 데이터를 수집하였다. 기 기의 연소 방식에는 제작사에 따라 연소 방식에 차이가 미미 하게 있었을 것으로 판단되며 데이터 변수의 개수가 늘어난다 면, SVR(support vector regression) 기반의 선형회귀 분석 등 을 실시하여 농업용 난방기의 이산화탄소 데이터가 온실가스 발생량 파악에 더욱 활용도가 높아질 것으로 판단된다. 추후 연구에서는 더욱 세분화된 데이터의 수집 방식을 따라 더욱 높은 정확도를 가진 결과값을 도출할 수 있다고 판단된다. 이 처럼 우리나라의 농업 분야에서 용도별 온실가스 발생량을 조 사하기 위하여 고정형 농기계인 농업용 난방기의 이산화탄소 발생량을 정확히 파악하여 온실가스 배출량 조사에 활용할 수 있을 것으로 판단된다.

이 연구는 한국과 호주 간 양자 협력 의제 중 자원 안보와 밀접한 관 련이 있는 탄소중립 기술 개발, 핵심 광물 공급망 그리고 농업 협력을 중심으로 살펴본다. 탄소중립 기술과 핵심 광물 공급망 같은 경우 2021 년 양국의 포괄적 동반자 관계 수립 이후 급격하게 협력이 시작되었고 정부와 주요 기업들이 적극적으로 참여하였다. 이에 반해 농업 협력은 2014년 양국의 자유 무역 협정 이후 협력위원회가 단 한 차례밖에 열리 지 않았다. 농업 협력은 향후 식량안보와 밀접한 관련이 있기에 협력이 순조롭게 진행될 수 있도록 노력을 기울일 필요가 있다. 향후 자원확보 와 공급망 구축이 그 무엇보다 중요한 시기에 양국의 상황을 면밀하게 관찰하고 부족한 부분의 협력을 적극적으로 모색하는 노력이 매우 중요 하다.

The purpose of this study was to explore the potential of agricultural heritage as a sustainable agricultural and rural paradigm with a focus on the “Argan-based agro-sylvo-pastoral system in the area of Ait Souab-Ait Mansour”, a Globally Important Agricultural Heritage Systems (GIAHS) site in Morocco. Based on the inscription criteria of the GIAHS, we analyzed the economic-industrial, sociocultural, and ecological-environmental perspectives and presented strategies for revitalizing agricultural and rural development cooperation through the Moroccan Argan GIAHS. The argan tree has been a source of economic, cultural, and environmental stability for the Berber people for centuries, but today it is exposed to many threats. In particular, the declining consumption of argan oil by Berbers, the lack of financial independence of women's cooperatives, and the over-exploitation of the tree suggest that it is time to balance the three pillars of environmental, economic, and social sustainability that development has sought to achieve. Agricultural heritage can be preserved when local people take ownership of their heritage and utilize it to generate economic activities. Only a symbiotic way of life between humans and agricultural heritage can overcome the possibilities and limitations of the ecological environment and generate local value through the accumulation of knowledge, technology, and culture. Only on these premises, can local self-sustaining development based on the pluralistic values and public functions of the world's important agricultural heritage be possible.

The purpose of the study was to analyze effectiveness of Korea’s bilateral development cooperation for the agricultural sector in Myanmar using secondary time-series data from 1991 and 2018. This study utilized the Vector Error Correction Model (VECM). Results showed that Korea’s bilateral development cooperation in the agricultural sector had a positive effect on the agricultural GDP in Myanmar with a significant contribution. This study suggests that the Myanmar government needs to use ODA (Official Development Assistance) for efficient and sustainable agriculture in a more timely and manageable manner. Although the agricultural sector in Myanmar has great potential for development, there are various weaknesses such as the lack of access to foreign aid compared to other ASEAN countries due to the lack of stability in policy legislation. If it formulates better agricultural policies, laws, and legislation, there would be more support from Korea and other partner countries than ever before.

스마트농업의 활성화를 위해서는 농업환경 데이터의 관측과 모델 그리고 통계자료의 상호운영성 확보가 중요하므로, 이를 위한 격자체계의 적용방안을 탐색하고자 한다. 국내외 격자체계 표준에 대한 사례조사와 농업분야의 격자표준 적용사례조사를 벤치마킹하고 국립농업과학원과 상위기관의 표준현황을 살펴보고, 농업환경 공간정보의 목록과 분류체계를 구축한 후, 사용자 요구사항을 파악하기 위한 설문을 실시하여 적정한 격자 크기를 선정하였다. 농업환경 공간정보의 공유와 활용을 위하여 국토지리 정보원의 기관표준을 차용하여 군 이하 소규모 지역은 10m, 광역시･도는 100m, 농촌경관 목적으로는 500m, 전국은 1km 격자 크기로 안을 제시하였고 원활한 표준 적용을 위한 전략을 제안하고, 현장 조사 및 관측 결과를 격자로 변환할 수 있도록 오픈소스 기반의 변환 툴을 개발하여 격자표준 적용 용이성과 시간 절약성을 확보하였다.
