$CO_2$ storage is a very important technology for reduction of greenhouse gas emissions and has been considered as almost the only viable and effective option for immediate large-scale $CO_2$ sequestration. Small-scale demonstration project for offshore $CO_2$ storage in the Pohang Basin is the transitional stage R&D program for technological preparation of large-scale $CO_2$ storage project in Korea. Through the extensive exploration research for prospective $CO_2$ storage sites, the offshore strata in the Pohang Basin was recommended for the storage formation of the small-scale demonstration project. The Pohang Offshore Storage Project launched at 2013, and has accomplished the technical demonstration and technological independence in a wide range of $CO_2$ storage technology, such as geophysical exploration, storage site characterization, storage design, offshore platform construction, injection-well drilling and completion, deployment of injection facility, operation of $CO_2$ injection, and $CO_2$ monitoring. The project successfully carried out $CO_2$ test injection in early 2017, and achieved its final goal for technical development and demonstration of $CO_2$ storage in Korea. The realization of $CO_2$ injection in this project is the measurable result and has been recorded as the first success in Korea. The Pohang Offshore Storage Project has a future plan for the continuous operation of $CO_2$ injection and completion of $CO_2$ monitoring system. The project has provided in-house technical and practical expertises, which will be a solid foundation for the commercial-scale $CO_2$ storage business in Korea. Additionally, the project will help to secure national technical competitiveness in growing international technology market for $CO_2$ storage.

At the beginning of the COVID-19 pandemic, Korea's wine market had shrunk as other countries. However, right after the pandemic, Korea's imported wine consumption had been increased 69.6%. Because of the ban on overseas travel, wine was consumed in the domestic market. And consumption of high-end wines were increased significantly due to revenge spending and home drinking. However, from 2022 Korea's wine market has begun to shrink sharply again. Therefore this study forecasts the size of imported wine market by 2032 to provide useful information to wine related business entities. KITA(Korea International Trade Association)'s 95 time-series data per quarter from Q1 of 2001 to Q3 of 2023 was utilized in this research. The accuracy of model was tested based on value of MAPE. And ARIMA model was chosen to forecast the size of market value and Winter's multiplicative model was used for the size of market volume. The result of ARIMA model for the value (MAPE=10.56%) shows that the size of market value in 2032 will be increased up to USD $1,023,619, CAGR=6.22% which is 101% bigger than its size of 2023. On the other hand, the volume of imported wine market (MAPE=10.56%) will be increased up to 64,691,329 tons, CAGR=-0.61% which is only 15.12% bigger than its size of 2023. The result implies that the value of Korea's wine market will continue to grow despite the recent decline. And the high-end wine market will account for most of the increase.

세계 물 시장은 지속적으로 성장하고 있는 추세로 현대경제연구원에서는 연 평균 5.5%씩 성장할 것이라고 예측한 바 있다. 또한 국내 수자원 개발은 거의 포화 상태에 도달하여 수자원 기업들이 해외 수자원 산업진출을 다각적으로 추진하고 있으므로 해외 수자원 사업에 대한 관심이 더욱 커질 전망이다. 해외 수자원 산업에서 국내 기업이 어려움을 겪는 부분 중 하나는 타당성 조사로 개발도상국에서 좋은 품질의 기상 및 수문 관측 자료를 확보하는 것이 어렵기 때문이다. 국내 기업들이 진출한 주요 해외 시장은 아시아와 아프리카이며, 진출 사례가 많은 아시아 지역에는 비교적 기상 및 수문자료 확보가 용이하나, 아프리카 지역은 자료의 확보가 어려운 상황이다. 특히 아프리카 지역은 수자원 현황이 열악하고 개발가능성이 높아 향후 국내 기업의 진출이 활발할 것으로 예측되는 지역으로 수자원 산업 진출을 위한 기상 및 수문자료 확보를 위한 노력이 필요하다. 본 연구에서는 해외 수자원 산업 진출의 기초자료 확보를 위해 아프리카 지역의 기상, 지형, 토양자료를 수집하고 수문자료 생산을 위한 지표수문해석 모델의 적용성을 평가하였다. 지표수문해석 모델로는 국내외에서 전지구 규모 수문해석에 활용성이 높다고 알려진 VIC (Variable Infiltiration Capacity)를 활용하였으며, 물수지 모의를 수행하였다. 기상, 지형, 토양자료는 미국 CPC (Climate Prediction Center), UMD(University of Maryland), FAO (Food and Agriculture Organization)의 전 지구 자료를 활용하였다. 아프리카 주요 유역에 대한 VIC 모델 적용성 평가결과 유출해석의 정확도가 유의미한 것으로 나타났다. 본 연구에서는 아프리카 대륙 규모의 기상, 지형, 토양자료를 확보하고 수문자료 생산 체계를 구축하였으며, 연구결과가 향후 국내 수자원 기업의 해외진출 및 전 지구 규모 수문연구의 기초자료로 활용될 수 있다는 점에서 가치가 있다.

Option pricing model in finance has been applied to price non-financial options, called real options. The real option valuation method is ideally suited to irreversible decision making under uncertainty, including the need to determine the optimal time to act and even change between alternative courses of action as information is collected. Therefore, the real option valuation method is expected to provide a superior and less subjective approach to determining optimal strategies for water resources supply projects, which have been reported to have huge risks due to uncertainties, and investors and policy makers need to build an optimal strategy - when and if to invest - with uncertainties and managerial flexibilities considered.

The public research and development (R&D) funds for construction engineering is one of the key elements for the advancement of construction industry. Korean Ministry of Construction and Transportation is currently planning to produce approximately US$ 500 millions of research funds every year in Korea from year 2007. Along with the prospect for increasing R&D investment, there is of increasing pressures on the development of quantitative methodologies for assessing the performance of construction R&D results. Although there have been some general R&D project evaluation methods, they are not readily used for construction R&D research assessment due to the distinct characteristics of construction R&D. This paper presents a simple methodology that can make quantitative assessments of construction R&D performances. The proposed methodology is expected to assist government officials in objectively evaluating construction R&D performances and identifying the areas that require more R&D investment.

While the renewable energy portfolio standard (RPS) is in place to expand the scale of renewable energy generation, the power producer can obtain the renewable energy credit (REC) and use it as an incentive to operate the facility. RECs secured by solar power generation can be traded through spot market or fixed price contracts, and, in the spot market trading, power producers are exposed to the uncertainty of REC spot price. In this study, real option analysis is conducted to analyze the optimal threshold of REC spot price for the conversion of REC trading method by power producer considering the uncertainty of REC spot price. We calculated the optimal threshold of REC spot price that can convert the trading method of REC from spot market to fixed price contract. In conclusion, the spot market trading is a rational trading method when considering the uncertainty of REC price, but the fixed price bidding is a rational trading method when not considering the uncertainty of REC price.
