Through comprehensive experimentation, we validated the efficacy of the system in accurately identifying anomalies, thereby propelling safety protocols forward during the fourth industrial revolution. This study signifies a significant stride toward fortifying the integrity and resilience of solar power distribution systems, which is pivotal for adapting to emerging technological paradigms and evolving safety standards in the energy sector. These findings offer valuable insights for enhancing the reliability and efficiency of safety management practices and fostering a safer and more sustainable energy landscape.

This study examines the multidimensional impacts of solar power deployment in rural areas on local communities using a system dynamics approach. A regional model was developed for Jeollanam-do, South Korea, integrating population dynamics, economic activity, land use, and carb on emissions. The simulation results indicate that while large-scale solar expansion significantly reduces net carb on emissions and increases regional income (GRDP), it accelerates population decline by diminishing rural landscape attractiveness. Notably, agrophotovoltaic (agroPV) systems were found to provide the most balanced outcome, mitigating population loss while achieving moderate economic benefits and substantial carbon reduction. These findings suggest that integrating solar power with agricultural land conservation, such as through agroPV, is essential for the long-term sustainability of rural communities.

This paper deals with high-Tc superconducting (HTS) power charging system with GdBCO magnet, photo-voltaic (PV) controller, and solar panels to charge solar energy. When combining the HTS magnet and the solar energy charging system, additional power source is not required therefore it is possible to obtain high power efficiency. Since there is no resistance in superconducting magnet carrying DC transport current the energy losses caused by joule heating can be reduced. In this paper, the charging characteristics of HTS power charging system was simulated by using PSIM. The charging current of HTS superconducting power charging system is measured and compared with the simulation results. Using the simulation of HTS power charging system, it can be applied to the solar energy applications.

본 연구의 목적은 공간정의 관점에서 지도, 임자, 안좌의 3개 지역 및 거주기간에 따라 신안군 개발이익공 유제에 대한 주민 만족도와 영향요인, 그리고 영향요인에 미치는 이익공유금과 거주기간의 통제 효과를 확인하는 것이다. 이를 위해 분배적, 절차적, 인정적 정의와 태양광 입지 요건에 대한 주민 인식을 Likert 척도로 조사 하고 통계적으로 분석하였다. 분석결과 주민 만족도는 지도읍과 임자면, 20년이상 40년미만 거주 주민의 만족도가 유의하게 높았다. 절차적 정의는 모든 지역, 모든 집단의 주민 만족도에 영향을 미치며, 인정적 정의 또한 중요한 영향요인 이었다. 두 요인은 이익공유금과 거주기간을 통제했을 때도 유의한 영향을 미쳤다. 일반적으로 햇빛연금으로 표현되는 신안군 개발이익공유제는 경제적 편익(분배 적 정의)에 대한 만족도가 높을 것이라고 생각하지만 본 연구 결과는 의사결정의 민주성과 정당성(절차 적 정의), 지역의 환경과 고유성에 대한 존중(인정적 정의)을 더 중요하게 인식하고 있음을 보여준다. 본 연구는 공간정의 프레임으로 신안군 개발이익공유제와 지역사회 변화를 분석했다는 데 의미가 있다.

The purpose of this study is to investigate and compare satisfaction levels of residents with the solar power development profit-sharing system and the factors affecting the satisfaction level in terms of the groups’ difference such as the length of residence, and the regions, from a spatial justice perspective. For this purpose, resident perceptions were surveyed using a Likert scale and the collected data were statistically analyzed. As a result of the analysis, the satisfaction level of residents was significantly higher in Jido-eup and Imja-myeon, and also higher for residents who have lived in the area for more than 20 years to 40 years. It was found that procedural justice has affected satisfaction level of residents in all regions and all groups. In general, the Shinan-gun development profit-sharing system is thought to have high satisfaction with economic benefits, but the results show that both procedural and recognitional justice are recognized as more important factors. This study is the first academic attempt to analyze development profit-sharing system using spatial justice frame.

Microcrystalline silicon thin film solar cells are fabricated with laser-assisted plasma enhanced chemical vapor deposition (LAPECVD) system at low temperature. An LAPECVD system is a unique combination of such developments that utilizes both laser and plasma to assist the relevant chemical reactions.

In order to help elementary students understand the astronomical unit in depth, this study applied backward design 2.0 to check the effect on students' science academic achievement, performance evaluation, and science class satisfaction. As a result of the study, there was no statistically significant difference in the science achievement test, but the average score of the experimental group has improved. As a result of the performance evaluation test, there was a statistically significant difference because the feedback was well provided through the process-focused assessment and it helped in-depth understanding. As a result of the science class satisfaction test, there was a statistically significant difference in the areas of science curriculum and peer relation except for the science teacher area. This is because a differentiated science curriculum was designed through analysis of achievement standards, and various teaching methods of student-centered were implemented to reach achievement standards. We hope this study will focus on the impact of backward design 2.0 on learners in elementary science classes and help find ways to effectively apply backward design 2.0 in the field.
