Building Information modeling is playing an important role in transforming the construction industry. It helped the industry with better visualization, minimum design errors, and excellent planning of the construction activities. Time and cost saving can be effectively achieved by using BIM for any construction project. It improves information exchange between all the project stakeholders. However, the development of earthwork 3D BIM is still underway and has not been fully implemented yet. This paper presents the study of a complete process for Earthwork BIM design using Autodesk Civil 3D. A real site road construction project is used as a case study to explain the process of earthwork modeling, starting from laser scanning to 3D model. Quantity take off calculation is very important part of any road construction project so during this study earthwork volume from two 3D earthwork model is calculated. The results obtained through this study will be the basis for future work which has been concluded in this paper.

The aim of this research is to enhance the bottom environment of Geoje fish farm that has been severely contaminated. Treatment of microbial agent and/or calcium oxide significantly changed that environment: in ignition loss, either treatment (25% or 21%) showed better than mixed treatment (13.2%). In COD, the oxygen releasing agent or mixed treatment reduced the index by more than 20%. In T-P and T-N, the effects of $CaO_2$ on them were overwhelming (50% or more) meanwhile that of the microbial agent on them was less than 20%. Also, $CaO_2$ influenced on the microbial flora: Desulfobvibrio thermophilus, a sulfate reducing bacterium decreased in number, considering the increase of pH and rise of redox potential. In contrast, Pseudomonas sp., Pseudoalteromonas sp., Pseudomonas aeruginosa were remarkably dominant over other species with mixed treatment as a PCA analysis confirmed it.

Coal has made a wonderful contribution to the production of cheap electricity. Coal based power plants have been the backbone of world's electricity for a long time now. Coal while being cheap and easily available is also a source of various solid, liquid and gaseous effluents which are responsible for the environmental degradation. Environmental issues caused by coal need to be studied and analyzed, then a common global consensus must be formed. Efficient action must be taken against each and every type of pollutant that is produced by this particular industry. The research aims to provide a brief overlook of the environmental impact of India's coal-based power plants. The aim of this study is to introduce a novel environmentally feasible energy scenario for the future of Indian power sector which has been named as "OPES". OPES is mathematically simulated using the combination of GAMS and LEAP. OPES is simple to comprehend and can be reproduced easily for other case studies as well. Results show that OPES can help the Indian power sector to minimize its environmental impact without causing any problems in the energy supply.

The ship recycling or scrap is a phenomenon in the process of vessels life cycle has ended in the shipping industry. Scrap are greatly affected by freight rates due to ship demands. Not only that, environmental regulation and economic scale vessel demand are processes that must exist in the shipping industry as they obtain management for existing vessels. In the past, shipbreaking yard had tried to work without protection for poverty, without poor working conditions and facilities to prevent the emission of harmful substances. However, the issue of environmental pollution has been raised the Basel and Hong Kong Convention have been adopted, and a new replacement of the ship scrap that induces serious pollution is required. In this study, 165 countries were analyzed to confirm the importance of determining the ship solution. As a result of the analysis, it was found that the Environmental Performance Index, which is a measure of environmental regulation, is the most influential factor of ship scrapped volume. The determinant of whether lower labor cost can be secured is more correlated with population than GDP per capita. The implications of the results of the regression analysis mean that if environmental regulations for ship scrap of the future are strengthened, the status of Bangladesh and Pakistan, which currently account for half of the world's ship recycling, may change.

The global apple processing industry generates millions of tons of apple pomace (AP) annually, leading to significant environmental challenges owing to improper disposal methods, such as landfilling, which releases methane and other contaminants. This mini-review provides a concise overview of the strategies for the upcycling and circular resource utilization of AP. Upcycling strategies for AP can contribute to environmental protection through carbon reduction and resource circulation using existing resources in new methods instead of new materials. Additionally, this review presents the potential of AP as a raw material for food, pharmaceuticals, and cosmetics while examining the technical, economic, and environmental challenges and necessary improvements for its optimal use. Overall, the upcycling of AP offers a valuable opportunity to improve waste management and promote efficient resource utilization.

본 연구는 지난 1995년부터 2007년 동안에 우리나라 제조업에서 산업별 에너지 소비가 해당 산업과 다른 산업에 어느 정도의 에너지 소비를 유도했는지에 대한 실증분석을 실시하였다. 본 연구에서 실시한 분석결과를 종합하면 다음과 같다. 첫째, 우리나라 제조업에서 에너지 소비가 이루어짐에 따라서 에너지 소비량을 증대시키는 총 산업연관효과는 감소하는 구조변동을 보였다. 이러한 산업구조적 변화는 산업별로 에너지소비의 전방효과 및 후방효과에서 유사한 결과를 나타내었다. 둘째, 우리나라 9개 산업 중에서 광물 및 금속관련 산업과 화학산업에서 해당 산업과 다른 산업들의 에너지 소비를 증대시키는 후방유발효과가 가장 크게 나타났다. 그러나 에너지 소비의 유발효과를 나타내는 간접후방효과는 1995년에는 화학 및 금속산업에서보다 다른 산업에서 상대적으로 크게 나타났으나 2007년에는 동일 산업에서 나타났다. 셋째, 에너지가 체화된 산업별 생산물의 활용 정도를 나타내는 전방효과의 경우에도 광물처리 및 금속산업과 화학산업이 가장 크게 나타났다. 후방효과와 달리 에너지 소비의 유발효과를 나타내는 간접전방효과는 전 기간 동안 화학 및 금속산업이 다른 산업에서 상대적으로 크게 나타났다. 본 실증분석결과로 볼 때, 2000년대부터 친환경산업육성정책의 정책효과는 우리나라 산업구조를 급격하게 에너지 절감형 구조로 전환시키고 있음을 보여준다.

This paper aimed to evaluate the test results of acute toxicity on effluent samples which were exempted from applying of ecotoxicity criteria. Total 316 effluent samples which were free from controlling of ecotoxicity regulation, were tested. Ratio of effluent samples which were exceeded the ecotoxicity criteria (TU > 1) indicated 23.7%. This ratio was a little bit higher than previous study (22.7%) on effluent samples which were controlled under ecotoxicity criteria. These results mean that our ecotoxicity management system is not appropriate and applying of ecotoxicity criteria to all effluent samples (82 industry categories) were needed in order to improve our ecotoxicity system. In addition, the same numeric criteria (TU 1 or 2) for all industry categories were proposed in consideration of these results. Ratio of effluent samples which exceeded the ecotoxicity criteria (TU > 1) with D. magna indicated 23.7%. However V. fischeri showed 14.6%. As a acute toxicity test organism, D. magna seemed to be more sensitive than V. fischeri. Ratio of samples which were exceeded TU 1 with D. magna by 24 h exposure period test indicated 35 %, whereas 48 h showed 41%.

We investigated practical methods of using recycled gypsum board paper in the paper industry. Gypsum board paper is used to produce construction gypsum board, and can be recycled through the recycling process of construction wastes. The experiments were carried out in two ways: One was the substitution of recycled gypsum board papers for KOCC, and the other was the use of recycled gypsum board paper powder. Recycled gypsum board paper was not disintegrated easily, but high temperature and the use of chemicals were able to improve their disintegration. The physical properties of handsheets made of the pulp of recycled gypsum board paper exhibited the same performance level as those made from KOCC except in the parameter of compressive strength. The powder of recycled gypsum board paper was manufactured using a grinder and handsheets were made with the powder and KOCC. The bulk was increased, but the strength properties were decreased by the addition of the powder.
