In this study, a solar light collector that collects and transmits solar light required for crop production in a closed plant production system was developed. The solar light collector consisted of a Fresnel lens for collecting solar light, and a tracking actuator for tracking solar light from sunrise to sunset to increase the light collection efficiency. The optical fiber that transmitted solar light was made of Glass Optical Fiber (GOF), and it had an excellent optical transmission rate. After collecting the solar light, the amount of light was measured at 5, 10, 15, 20, 25, and 30 cm distances from the GOF through the darkroom by using a light sensor logger connected to a quantum and pyranometer sensor. Compared with solar light, the light intensity of pyranometer sensor measured at 5 cm was 114% higher than solar light, and 61% at 10 cm. In addition, it was observed that it is possible to transmit the necessary amount of light for growing crops up to about 15 cm (as over 22%) through GOF. Therefore, adding diffusers to the solar light collector should be expected to replace artificial light in plant factories or plug seedlings nurseries for leafy vegetables. More studies on the solar light collection devices and the light transmission devices that have high light collection efficiency should be conducted.

Rural spaces are experiencing an increasing demand for novel functionalities and adaptations driven by technological advancements in agriculture and rural areas. This study aimed to investigate the public perception of rural spaces in the context of evolving agricultural technologies, specifically focusing on photovoltaic power generation, and the ensuing competition among various functions of rural spaces. A survey was conducted with a participant sample of 330, revealing that the majority of respondents prioritize agricultural production as the primary function of farmland. Furthermore, the survey results indicated that the installation of solar panels on farmland is perceived as a complex issue that affects multiple aspects, such as the landscape, local economy, ecological environment, climate change, and income. Additionally, disparities in responses to landscape-related questions were observed based on age, perception of agricultural land functions, and opinions on technological adoption. This finding suggests that the landscape is poised to become a significant factor in future agricultural and rural transformations. The findings of this survey can provide valuable contributions to the preparation of changes catalyzed by advancements in agricultural technology. Moreover, they offer guidance on the key factors that need to be taken into account when introducing new functions to rural spaces.

In this study, we classified and analyzed the type and cause of resident conflicts and made a solution at side of resident through resident survey study for research subjects located at photovoltaic system will be installed or not. The factors of resident conflicts based on news media release from 2006 to 2018 were classified to four types such as economic, environmental, technological and procedural factors. According to the news analysis, the types and proportion of resident conflicts in the photovoltaic system projects showed 33% of economic factors, 32% of environmental factor, 21% of technological factor and 14% of procedural factor. This news analysis may suggest that it is very important residents to share the economic benefits as well as to ensure the fairness of the procedures for carrying out the project based on transparent information disclosure during the business promotion and profit distribution stages. We conducted the poll survey in the rural towns where photovoltaic system will be installed or not. The poll survey results showed that (i) there is quite difference in agreement rate and other recognition for sensitive matters such as profit distribution, environmental and technological factors whether photovoltaic system will be installed or not, (ii) the resident conflict regarding the photovoltaic system installation can reduce through direct involvement of residents process. To solve these resident conflicts, the local governments should mainly effort and consider the supporting technologies and consults to solve clearly resident conflicts. In addition, it has to advertise the safety of photovoltaic systems regarding electromagnetic wave which were within the range of scientifically harmless to the human body.

This study investigated the status of resident participation in the policy of supplying new and renewable energy in rural areas. According to the survey, most of the rural residents were well aware of the new and renewable energy supply project promoted by the government. However, it was found that participation in the project was difficult mainly for economic and social reasons. In order to activate the participation of rural residents who can't participate in the renewable energy power generation project for economic and social reasons, it is necessary to develop and promote business models and support policies for power generation projects in which village communities participate. Changes in residents' acceptability due to resident education and operation for solar power systems were analyzed. As a result of the survey, it was found that the satisfaction of rural residents was high when new and renewable energy power generation projects were introduced in rural areas. Therefore, it is thought that the government's goal of increasing farm household income and expanding the supply of new and renewable energy in rural area can be successfully achieved by the improvement of resident acceptability and the increase of the participation rate. Lastly, this study presented a plan to improve the resident acceptability of the renewable energy system by using the rural solar project and survey results.

국토 면적의 약 90%를 차지하는 농촌은 여러가지 공익적 기능을 수행하는 공간으로서 중요성과 가치가 증가하고 있지만 주거지 인근에 축사, 공장, 태양광패널 등 주민생활에 불편을 미치는 시설들이 무분별하게 들어서면서 농촌 환경과 경관이 훼손되고 주민 삶의 질이 낮아지고 있다. 농촌지역의 무질서한 개발을 방지하고 농촌 공간을 계획적으로 관리하기 위해서는 농촌지역 내 위해시설에 대한 탐지 및 모니터링이 필요하다. 주기적으로 취득 가능하고 전체 지역에 대한 정보를 얻을 수 있는 위성영상을 통해 데이터의 취득이 가능하고, 합성곱 신경망 기법을 통한 영상 기반 딥러닝 기술을 활용하여 효과적인 탐지가 가능하다. 따라서 본 연구에서는 의미적 분할(Semantic segmentation)에서 높은 성능을 보이는 U-Net 모델을 이용하여 농촌 지역에서 잠재적으로 위해시설이 될 수 있는 농촌시설을 분류하는 연구를 수행하였다. 본 연구에서는 2020년에 제작된 공간해상도 0.7 m의 KOMPSAT 정사모자이크 광학영상을 한국항공우주연구원으로부터 제공받아 사용하였으며 축사, 공장, 태양광 패널에 대한 AI 학습용 데이터를 직접 제작하여 학습 및 추론을 진행하였다. U-Net을 통해 학습시킨 결과 픽셀 정확도(pixel accuracy)는 0.9739, mean Intersection over Union (mIOU)은 0.7025의 값을 도출하였다. 본 연구 결과는 농촌 지역의 위험 시설물 모니터링에 활용될 수 있으며, 농촌계획 수립에 있어 기초 자료로 활용될 수 있을 것으로 기대된다.

영농형 태양광은 동일 토지면적에서 태양광 패널에 의한 발전과 작물 경작을 융합한 시스템이다. 광 에너지가 부족한 영농형 태양광 하부에서 작물의 수확량이 감소하는 것은 필연적이나, 이를 관장하는 패널 하부에서 생육한 작물의 광합성 반응에 대해서는 국내외적으로 거의 알려진 바가 없다. 본 연구는 고정형 영농형 태양광 시설 하부에서 재배된 작물 잎에 흡수된 광에너지가 광합성 반응 중심에 전달되고 열로 방출되는 효율을 엽록소 형광 관측을 통해 조사하였다. 패널 하부와 노지의 콩과 벼는 ETR에서 큰 차이가 없는 것으로 보아 광인산화 효율보다는 잎이 흡수한 광 에너지에 따라 CO₂ 고정량이 결정되는 것으로 보인다. 또한, 패널 하부의 콩과 벼는 노지보다 NPQ가 더 높은 것으로 보아 활성화된 광보호기작이 광인산화로의 에너지 분배에 부정적 역할을 할 수 있을 것으로 보인다. 향후 영농형 태양광에서의 작물 생산량과 광합성의 관계를 이해하기 위해 보다 다양한 기후 및 재배조건에서의 광합성 반응을 조사할 필요가 있겠다.
