최근 수질오염원 중에서 비점오염원의 영향 높아지고 있다. 특히, 농경활동에서 유래되는 비점오염원이 공공수역의 수질에 미치는 영향이 증가하고 있다. 농경지에서 배출되는 비점오염원은 관리대상 면적이 넓어 비점오염 배출을 저감하기 위해서는 사전예방적 차원에서 접근이 필요하다. 하지만, 비점오염원에 대한 농업인과 주민들의 인식 부족으로 인하여 관리에 많은 어려움이 있다. 근래에 농업 비점오염원 저감을 위한 노력으로 물리적 기술적 접근만이 아니라 사회 문화적 접근이 병행되어야 한다는 점이 강조되고 있다. 따라서 본 연구에서는 농업 비점오염원 관리를 위한 사회문화적인 접근 방법으로서 전형적인 한국의 농촌 마을에서 농업 비점오염원에 대한 인지도 향상과 자발적 저감활동 실천 참여를 유도하기 위하여 개발된 역량강화 교육프로그램이 교육 대상자인 농업인, 주민, 마을지도자의 인식변화에 미치는 효과를 살펴보았다. 역량강화 프로그램은 농업인과 지역주민, 마을리더의 인문사회적 특성을 고려하여 공통과정과 맞춤형 과정으로 구성하였다. 농업인은 농업비점오염 저감에 적용할 수 있는 시비관리와 배수 물고관리, 영농폐기물 관리, 친환경농업에 대한 내용으로 구성하였다. 마을주민은 고령화된 여성의 비율이 높은 것을 고려하여 분리수거, 쓰레기 문단투기 및 소각, 마을 미래상과 환경실천에 대해서 교육하였다. 마을리더에게는 공동체 활성화 리더쉽, 주체적 주민참여, 갈등관리에 대한 내용으로 구성하였다. 공통적으로는 비점오염원과 농업 비점오염원의 정의와 유형, 마을환경관리 실천활동, 친환경농업 선진지 견학으로 구성하였다. 교육프로그램은 2년 동안 진행되었으며 마을별로 방문하여 진행하였다. 농촌 마을에서 농업비점오염원 역량강화 교육 프로그램의 효과는 다음과 같다. 교육 전의 소극적 참여의사에서 적극적인 활동 참여로 발전하였으며, 비점오염원에 대한 인식 및 관리 필요성에 대한 인식이 개선되었다. 농업 비점오염원 보다는 일반적인 비점오염에 대한 인지효과가 높게 나타났다. 따라서 농촌지역에서 농업비점에 대한 인식 변화가 저감활동 실천으로까지 이루어지는 가시적 효과를 거두기 위해서는 장기간이 소요됨을 시사하였다.

This study attempted to study the soil erosion dynamic in the Bagmati Basin of Nepal. In this study, an inclusive methodology that combines Revised Universal Soil Loss Equation (RUSLE) and GIS techniques was adopted to determine the distribution of soil loss in the study basin. As well, this study attempts to study the intensity of soil erosion in the seven different land use patterns in the Bagmati Basin. Soil loss is an associated phenomenon of hydrologic cycle and this dynamic phenomenon possesses threats to sustainability of basin hydrology, agriculture system, hydraulic structures in operation and overall ecosystem in a long run. Soil conservation works, and various planning and design of watersheds works demands quantification of soil loss. The results of the study in Bagmati Basin shows the total annual soil loss in the basin is 22.93 million tons with an average rate of 75.83T/ha/yr. The computed soil loss risk was divided into five classes from tolerable to severe and the spatial pattern was mapped for easy interpretation. Also, evaluation of soil loss in different land use categories shows barren area has highest rate of soil loss followed by agriculture area. This is a preliminary work and provides erosion risk scenario in the basin. The study can be further used for strategic planning of land use and hydrologic conservation works in a basin.

For drones to be used for industrial or agricultural applications, it is necessary to increase the payload and endurance. Currently, the payload and endurance are limited by the battery technology for electric powered drones. In addition, charging or replacing the batteries may not be a practical solution at the field that requires near continuous operation. In this paper, a procedure to optimize the power system of an electric hybrid drone that consists of an internal combustion engine, a generator, a battery, and electric motors is presented. The example drone for crop dusting is sized for easy transportation with a maximum takeoff weight of 200 kg. The two main rotors that are mechanically connected to the internal combustion engine provides most of the lift. The drone is controled by four electric motors that are driven by the generator. By analyzing the flow of the energy, a methodology to select the optimum propeller and motor among the commercially available models is described. Then, a procedure of finding the optimum operational condition along with the proper gear reduction ratios for the internal combustion engine based on the test data is presented.

Saemangeum Development is the largest national project in South Korea, which has been developed for an agricultural, economic and tourist area for 30 years from 1987. In order to convert power sources that used to depend on nuclear and thermal power to eco-friendly for carbon reduction, the government plans to construct a 2.1GW floating photovoltaic project by investing 4.6 trillion won, as a public-private project. For success of the Saemangeum floating photovoltaic project, economic feasibility should be checked. This study defined the factors (construction cost, electricity selling price, power generation and maintenance cost) that give a effect to the volatility of the floating photovoltaic payoffs, and analyzed the volatility of payoffs during 20 years operation period. NPV and option value of the project were calculated by applying an option to abandon. According to NPV analysis, it is determined that projects are difficult to invest. But this project has economic feasibility through real options analysis. This study is expected to help decision-makers in the economic analysis of floating photovoltaic projects by using the real options analysis.

Background and objective: There are many theories related to the development of agrotourism, and each stakeholder has its own role and function. If it is based on organizational functions, stakeholders need to be coordinated, and the state plays a major administrative role. But in the successful case of Yeongdong County, Chungcheongbuk province, the Republic of Korea, the government played an important role in the development of tourism, which grants us another perspective on the role of the government in promotion and development agrotourism activities. Methods: This article aims to examine the development of agrotourism through a cooperative approach, by clarifying the role of the local authorities in the Yeongdong region in the management and operation of the local agrotourism activities. The qualitative research method is based on a field survey conducted in Yeongdong County in 2019. Results: The study's findings show that in situations where conflicts of interest among stakeholders are prone to occur, the development of local tourism has a limited impact on the cooperative culture, and local governments play an important role. Accordingly, the local governments must actively formulate strategies to maintain and develop traditional agricultural industries and at the same time develop agrotourism activities. The government's ability to coordinate, cooperate, and participate reasonably is a key factor for the success of the sustainable development of the tourism industry. Conclusion: Based on coordination between stakeholders and a reasonable strategic direction, Yeongdong's agrotourism is being effectively deployed. The development of Yeongdong's agrotourism industry has achieved impressive results through an effective strategy, highlighting the important role of localgovernment in the consensus of local communities and collaboration with stakeholders. The role of outstanding local governments has been clearly demonstrated, especially in promoting, establishing, and contacting different organizations to effectively deploy agrotourism in the region.

Interest and investment in drones that apply the concept of the 4th industrial revolution and ICT convergence advanced technology are continuing. The purpose of drone operation has been widely spread from the initial military use to the use of various industries such as construction, forestry, facilities, and agricultural support. In these industries, the training of pilots who can actually operate drones is increasing centering on the qualification system. However, the detailed standards including the training place, training place, educational environment, and education method for nurturing pilots are ambiguous, so the education through the oral instruction of the training instructor is continuing at the drone training site. In order to solve this problem, this study conducted a study on a dual control platform in which a training instructor could directly intervene in the pilot's flying drone to execute a map in order to improve the quality of synesthesia, which is essential in the field.

This study attempted to suggest the factors that facilities that aim to exchange urban-rural coexistence base spaces with urban-rural areas should have. In order to derive factors, 15 literatures preceded by similar studies were investigated, and systematic classification was attempted. Finally, the factors for activating urban and rural base facilities were organized into 3 categories, 9 sectors, and 30 activation factors. The three major categories consisted of resources and facilities, content and programs, operational status. As a result of the AHP survey, in the survey area, which is a categories, resources and facilities composed of hardware factors originally possessed by the facility showed the highest score of 48.9. In the sectors, the convenience of facility use was 25.7 points, and the rich state of tangible and intangible resources was 13.3 points in order. In the sectors, income from paid experience programs at facilities was 8.3 points, physical accessibility to facilities was 8.2 points, and the type of areas where the facilities were located was 7.7 points in order. It showed high importance in the order of resources and facilities composed of hardware factors, content and programs composed of software factors, and manpower and operation composed of humanware factors. In general, it was shown that the physical factors of the place when using urban and rural base facilities were judged as the main factors.
