        This experiment was carried out to examine double cropping system using Italian ryegrass (IRG) 'Kowinearly', whole crop rice 'Yeongwoo' and barnyard millet 'Jeju native' during the Oct. 2020 to Oct. 2022. Three kinds of forage crops were cultivated at paddy field in Livestock Institute, Jeollanamdo Agricultural Research and Extension Services, Jeollanamdo, South Korea. Whole crop rice (WCR) was sown in late May and barnyard millet (BM) sown early June each year after harvesting IRG. We examined dry matter yield and feed value of forage crops depending on harvest time of forage crops during the experimental period. The plant height in heading stage of IRG ranged from 108 to 112cm and dry matter yield ranged from 6,783 to 11,530 kg ha-1. The crude protein (CP) of IRG ranged from 6.0 to 8.44%, acid detergent fiber (ADF) ranged from 55.6 to 60.2% and neutral detergent fiber (NDF) ranged from 32.58 to 36.7%, The dry matter yield of WCR increased as the harvest stage was delayed (14,310 kg ha-1 in milk, 16,167 kg ha-1 in yellow ripen, and 18,891 kg ha-1 in mature). Similar to results of dry matter yield of WCR, dry matter yield of BM increased as the harvest stage was delayed (11,194 kg ha-1 in late heading. and 14,308 kg ha-1 in mature), However nutrient content of WCR and BM showed a decreasing trend. As shown in above results, the productivity of WCR after harvesting IRG was shown to be high at paddy field in the southern region. However, BM also was appeared to have potential as summer forage crops.

        중국에서 시작된 목판 인쇄술은 부처님 말씀을 전하기 위한 방법으로, 처음에는 글자 위 주였으나, 글자 속에 삽화로 판화가 결합되면서 강력한 포교의 수단으로 등장하였다. 책속의 삽화를 한 장의 판화에 모아 불화 형태로 제작되어 보급되기도 하였으며, 삽화 형태를 벗어 나 한 장의 만다라 형태로 극락의 세계를 표현하여, 불자들이 생활 속에서 자연스럽게 지옥 에 떨어지지 않기 위해 악을 멀리하여 선을 행하여, 고해의 바다인 사바세계를 벗어나 극락 세계에 태어나길 염원할 수 있도록 유도하기도 하였다. 한국 고판화박물관이 소장하고 있는 한국, 중국, 일본, 티벳, 베트남 등의 ‘정토’ 관련 소장품은 목판(木板)과 전적(典籍)과 불화 판화(佛畵版畵), 민속판화 등으로 분류될 수 있으며, 각 나라에서는 책속의 삽화와 불화, 명 절이나 조상을 천도하는 제사 등에 사용된 지전(紙錢)이나 부적 등으로 다양하게 발전되어 사용해 왔음을 알 수 있다. 중국에서 시작된 정토의 모습을 책 속의 삽화 형태로 발전시킨 정토삼부경인 아미타경(阿彌陀經)이나, 관무량수경(觀無量壽經), 무량수경(無量壽經) 등 이 한국, 일본 등에서 복각復刻되어 발간되었으며, 일본에서는 정토삼부경이 만다라 형식의 불화 판화로 독자적인 형태로도 발전되었음도 알 수 있다. 정토 불교가 발전되었던 일본에서 는 그림으로 교리를 설명하는 에토키(etoki)로 다양한 정토 불화 판화가 보급되어 예배와 교 화의 도구로서 사용되었으며, 중국에서는 조상을 천도하는 의식에 사용된 지전이나 부적의 형태로 다양하게 사용되어 왔음도 알 수 있다. 이를 통해 우리는 불교 포교의 새로운 수단으로 고판화를 활용하는 방법을 모색할 필요가 있으며, 나아가서는 동아시아인들의 생사관(生 死觀)을 고판화를 통해 더욱 쉽게 이해 할 수 있어 동양 문화를 더욱 심층적으로 연구 발전 시키는 데 동아시아 각국의 고판화의 수집과 활용이 주요한 수단이 될 수 있음을 직시할 필 요가 있다. 더 나아가서는 불교 회화의 연구를 위해 동아시아의 손으로 그린 불화와 판화로 찍은 불화와의 비교 분석을 통해, 불교회회사의 새로운 지평을 열 필요가 있다.

        The external weather conditions including temperature and wind speed in the Saemangeum reclaimed land is different from that of the inland, affecting the internal environment of the greenhouse. Therefore, it is important to select an appropriate covering material considering the insulation effect according to the type and characteristics of the covering material considering the weather condition in the Saemangeum reclaimed land. A hexahedral insulation chamber was designed to evaluate the insulation efficiency of each glass-clad material in the outside weather condition in reclaimed land. In order to evaluate the insulation effect of each covering material, a radiator was installed and real-time power consumption was monitored. 16-mm PC (polycarbonate), 16-mm PMMA (polymethyl methacrylate), 4-mm greenhouse glass, and 16-mm double-layered glass were used as the covering materials of the chamber. In order to understand the effect of the external wind directions, the windward and downwind insulation properties were evaluated. As a result of comparing the thermal insulation effect of each greenhouse cover material to single-layer glass, the thermal insulation effect of double-layer glass was 16.9% higher, while PMMA and PC were 62.5% and 131.2% higher respectively. On average the wind speed on the windward side was 53.1% higher than that on the lee-wind side, and the temperature difference between the inside and outside of the chamber at the wind ward side was found to be 52.0% larger than that on the lee ward side. During the experiment period, the overall heating operation time for PC was 39.2% lower compared to other insulation materials. Showing highest energy efficiency, and compared to PC, single-layer glass power consumption was 37.4% higher.

        It is essential that continual assessments of the impact of mine-derived water as a long-lasting burden on freshwater environments. Abundance-based evaluations of benthic macroinvertebrates have been conducted to evaluate anthropogenic disturbances and devise policies to reduce their impact. In this study, the status of a stream habitat was evaluated based on the body length and biomass weight of benthic macroinvertebrates of the family Baetidae. Following the renewal of the mining water treatment plant, the abundance of Baetidae assemblages recovered to a level comparable to that of a reference site. However, relatively low values were found for both body length and biomass weight in Baetidae species inhabiting the reddened streambed area, suggesting that the habitat has not yet been completely recovered despite the recovery of the abundance of the Baetidae assemblages. Therefore, continuous investigation and evaluation of this disturbed stream are necessary until their growth conditions of the habitat have functionally recovered

        This study was conducted to identify the distribution characteristics of the impervious area in urban watersheds and to reduce the deviation of the impervious area ratio that occurs depending on the degree of construction of land surface condition data. The average impervious area ratio by land use that can be applied to the calculation of the urban impervious area ratio was derived by statistically analyzing the distribution characteristics of the impervious area ratio by land use according to the urban watershed conditions. In urban watersheds, the change in impervious area ratio over the past 20 years has continuously increased in watersheds with an impervious area ratio of less than 60%, and decreased in watersheds with a high impervious area ratio of 60% or more. The average impervious area ratio by land use applicable to the land use technique is “Residential area” 84.0%, “Residential and commercial mix” 93.6%, “Commercial and business facilities” 89.8%, “Industrial land” 84.8%, “Public land” 47.3%, “Transportation facility” 93.3%, “Urban revitalization facility” 61.1%, “Bare land” 17.6%, “Special area” 11.4%, “Forest and open space” 3.5%, “Rivers and lakes” 9.2%. As a result of examining the adequacy of the average impervious area ratio by land use, the difference between the calculated value of the impervious area ratio using land use techniques and the actual impervious area ratio of the biotope map ranged from -3.0%p to 2.6%p at the significance level of 95%. In addition, when the watershed condition is applied, the difference ranged from -2.3%p to 1.7%p. By applying the average impervious area ratio by land use derived in this study, it was found that the impervious area ratio of the target urban watershed could be calculated within a deviation of ±3%p.

        Urban areas in watersheds increase the impervious surface, and agricultural areas deteriorate the water quality of rivers due to the use of fertilizers. As such, anthropogenic land use affects the type, intensity and quantity of land use and is closely related to the amount of substances and nutrients discharged to nearby streams. Riparian vegetation reduce the concentration of pollutants entering the watershed and mitigate the negative impacts of land use on rivers. This study analyzes the data through correlation analysis and regression analysis through point data measured twice a year in spring and autumn in 21 selected damaged tributary rivers within the Han River area, and then uses a structural equation model to determine the area land use. In the negative impact on water quality, the mitigation effect of riparian vegetation was estimated. As a result of the correlation analysis, the correlation between the agricultural area and water quality was stronger than that of the urban area, and the area ratio of riparian vegetation showed a negative correlation with water quality. As a result of the regression analysis, it was found that agricultural areas had a negative effect on water quality in all models, but the results were not statistically significant in the case of urban areas. As a result of the model estimated through the structural equation, BOD, COD, TN, and TP showed a mitigation effect due to the accumulation effect of river water quality through riparian vegetation in agricultural areas, but the effect of riparian vegetation through riparian vegetation was found in urban areas. There was no These results were interpreted as having a fairly low distribution rate in urban areas, and in the case of the study area, there was no impact due to riparian forests due to the form of scattered and distributed settlements rather than high-density urbanized areas. The results of this study were judged to be unreasonable to generalize by analyzing the rivers where most of the agricultural areas are distributed, and a follow-up to establish a structural equation model by expanding the watershed variables in urban areas and encompassing the variables of various factors affecting water quality research is required.

        Today, we are living in an era of city. Many cities around the world are exposed and vulnerable to natural disasters and environmental pollution due to rapid urbanization and population concentration. Most of these city problems occur in space and as a solution to all these problems, Digital Twin is continuouslybeing introduced. A digital urban space infrastructure and multi-dimensional spatial data analysis are required to effectively solve and deal with various city problems. One of problem in land administration aspect, to change ownership and get a permit take a long time. In order to improve this situation, digital twin concept is proposed. It’s operation and management became possible as the information systems took a transition from paper to computerized files, from files to integrated databases, from two-dimensional to three-dimensional data, and as transition took place, the need for a virtual urban space or "DigitalTwin" that can integrate distributed urban data into one came to fore. In this study, the new preprocess was suggested to use Digital Twin concept in order to reduce time line and to make an efficient work process for land administration.

        Among migratory insect pests, Mythimna seperata and Cnaphalocrocis medinalis are invasive pests introduced into South Korea through westerlies from southern China. M. seperata and C. medinalis are insect pests that use rice as a host. They injure rice leaves and inhibit rice growth. To understand the distribution of M. seperata and C. medinalis, it is important to understand environmental factors such as temperature and humidity of their habitat. This study predicted current and future habitat suitability models for understanding the distribution of M. seperata and C. medinalis. Occurrence data, SSPs (Shared Socio-economic Pathways) scenario, and RCP (Representative Concentration Pathway) were applied to MaxEnt (Maximum Entropy), a machine learning model among SDM (Species Distribution Model). As a result, M. seperata and C. medinalis are aggregated on the west and south coasts where they have a host after migration from China. As a result of MaxEnt analysis, the contribution was high in the order of Land-cover data and DEM (Digital Elevation Model). In bioclimatic variables, BIO_4 (Temperature seasonality) was high in M. seperata and BIO_2 (Mean Diurnal Range) was found in C. medinalis. The habitat suitability model predicted that M. seperata and C. medinalis could inhabit most rice paddies.
