Two-Stage Neural Network Optimization for Robust Solar Photovoltaic Forecasting

Neural networks (NNs) have shown outstanding performance in solar photovoltaic (PV) power forecasting due to their ability to effectively learn unstable environmental variables and their complex interactions. However, NNs are limited in their practical industrial application in the energy sector because the optimization of the model structure or hyperparameters is a complex and time-consuming task. This paper proposes a two-stage NN optimization method for robust solar PV power forecasting. First, the solar PV power dataset is divided into training and test sets. In the training set, several NN models with different numbers of hidden layers are constructed, and Optuna is applied to select the optimal hyperparameter values for each model. Next, the optimized NN models for each layer are used to generate estimation and prediction values with fivefold cross-validation on the training and test sets, respectively. Finally, a random forest is used to learn the estimation values, and the prediction values from the test set are used as input to predict the final solar PV power. As a result of experiments in the Incheon area, the proposed method is not only easy to model but also outperforms several forecasting models. As a case in point, with the New-Incheon Sonae dataset—one of three from various Incheon locations—the proposed method achieved an average mean absolute error (MAE) of 149.53 kW and root mean squared error (RMSE) of 202.00 kW. These figures significantly outperform the benchmarks of attention mechanism-based deep learning models, with average scores of 169.87 kW for MAE and 232.55 kW for RMSE, signaling an advance that is expected to make a significant contribution to South Korea’s energy industry.

The purpose of this study was to determine moderating effect of person-centered care on relationship between organizational commitment and LTC service quality among caregivers working in long-term care facilities. This study also aimed to determine which aspects of person-centered care having a more moderating effect. Person-centered care has recently received much attention in the care field. It is a perception and practice that emphasizes the independence and autonomy of service recipients. A survey was conducted among caregivers working in facilities in Incheon area. A total of 190 returned questionnaires were analyzed in this study. Results showed that the moderating effect of person-centered care was statistically significant in the relationship between organizational commitment and service quality of long-term care. When person-centered care was analyzed by dividing it into sub-factors, individualization and autonomy, autonomy, but not individualization, was statistically significant. Based on these findings, recommendations on some service policies and practices including ways of care worker education and on-the-job training programs in a nursing home were made for improving the quality of caregivers' services and for further research.

Detection of pesticide residues and risk assessment from the local fruits and vegetables in Incheon, Korea

This study was conducted to investigate the pesticide residue concentrations and assess potential human health risks from fruit and vegetable consumption in Incheon. A total of 1,146 samples of 20 different types of fruits and vegetables were collected from the Incheon area in 2020. The pesticide residues were analyzed by the multi-residue method of the Korean Food Code for 400 different pesticides. Among the fruit and vegetable samples, 1,055 samples (92.1%) were free from detectable residues, while 91 samples (7.9%) contained residues and 11 samples (1.0%) had residues exceeding the Korean maximum residue limit. A total of 32 different pesticide residues were found and 8 residues exceeded MRLs. The most frequently detected pesticide residues were chlorfenapyr, procymidone, etofenprox, pendimethalin, fluopyram and azoxystrobin. The highest values of short term and long term exposure were obtained in the case of consumption of lettuce(leaves) with chlorfenpyr. For chronic dietary exposure, the cumulative hazard index (cHI) were below 100%. The results of this study showed that the detected pesticides were not exposed to potential health risks through the consumption of fruits and vegetables.

일반학교, 혁신학교, 정다운 학교에서의 통합교육 경험과 인식

The purpose of this study was to discover the differences and commonalities between school types by comparing and analyzing the experiences of teachers and parents in general schools, innovative schools, and Jeongdaun schools. For this purpose, inclusive education experiences were collected and analyzed through interviews with a total of nine teachers in charge of integrated classrooms, special education teachers, and parents from three types of schools in the Incheon area. The main findings were as follows. First, five conclusions were derived on experiences and perceptions on inclusive education in three school types: 1) There was a clear difference in the degree of inclusive education between the three schools. In general, the inclusive education situation of innovative schools and Jeongdaun schools was more positive than that of general schools; 2) In all three schools, inclusive education relied heavily on individual teacher competency and personal acquaintance with teachers rather than systems or regulations; 3) The perception of managers and teachers in charge of inclusive classrooms still needs improvement. Education for disability awareness should be more professional in teacher education institutes and in each school; 4) For parents of children with disabilities, inclusive education was the necessary and urgent option; 5) There was a difference in conception on inclusive education among the three types of schools. Second, for inclusive education to succeed, it was especially necessary to document each group’s performance within their responsible roles, and to supplement the education process with para-professionals.

야간형 축제와 관광이벤트가 도시재생지역에 미치는 영향인식 비교분석 : 군산과 인천의 비교를 중심으로

This study was conducted to compare and analyze how the perceived impact of strategically planned night-time festivals and events in the ciyies of Incheon and Gunsan on urban regeneration areas differed. First, as a result of verifying the differences between the cities of Incheon and Gunsan, the host regions, the night-time festivals and tourism events, it is believed that Incheon has a more direct impact on urban regeneration with night-time festivals and tourism events than Gunsan. In particular, the Incheon area has a traditional market near the venue where night festivals and tourism events are held, which is believed to have greatly affected the market revitalization as visitors flowed into the market before and after the event. Second, the difference between the Incheon Open Port Cultural Heritage Night, Dongincheon Romantic Market, Gunsan Cultural Night, and Gunsan Time Travel Festival, shows that Gunsan has a lower urban regeneration impact than Gunsan. Therefore, it is believed that software-based urban regeneration strategies using nighttime festivals and events should be expanded around urban regeneration areas. Based on the final results of this study, night festivals and tourism events can directly affect the software regeneration effect in urban regeneration areas. Therefore, efforts are needed to draw active participation from local residents to help establish urban regeneration strategies and policies. However, the limitations of this study are determined to be excessive in applying various results to festivals and events with similar characteristics during the day and night in Incheon and Gunsan. Therefore, it seems necessary to compare various objects to see how similar festivals and events occurring in urban regeneration areas affect the region in the future.

인천지역 유통 수산물 및 수산물가공품 중 미세플라스틱 오염도 조사

This study was intended to obtain the basic data for a wide range of microplastics (MPs) contamination studies. The contamination of MPs in seafood and processed seafood products distributed in Incheon area was quantified. For this, 51 seafoods and 50 processed seafood products in Incheon were collected randomly from January 2019 to October 2019, and the abundance, size, and type of MPs in the samples were identified by FT-IR spectroscopy. The average MPs content was 1.06±3.38 MPs/g and 0.89±1.29 MPs/g in seafoods and processed seafood products, respectively. In both samples, MPs of 100-500 μm accounted for the majority of the particles, with the most common MPs as polyethylene (PE) and polypropylene (PP). However, the level of contamination of MPs in each of the samples was significantly different, even for the same species. For more accurate analysis of MPs contamination in seafoods and processed seafood products, specific information such as habitat, environment, market supply, regional source, and production process might be required. In addition, extensive and continuous accumulation of data is necessary for them to be used as the basic data with a standardized method for analyzing MPs.
