본 연구는 H대학 전교생 필수인 IT 교과목 강의평가에 영향을 주는 요인에 대해 비교 분석하였다. 본 연구의 목적은 강의만족도가 학업성취도, 출석율, 수강과목군과 유의미한 상관관계를 가지는지 파악하는 것이다. 특별히 컴퓨터를 활용하는 실습이 많이 요구되는 IT 교양과목들의 강의 만족도가 일반 교양과목의 강의만족도 경향과 어떤 차이가 있는가를 확인하고자 하였다. 본 연구를 위해서 H 대학교에서 2019년도 1, 2학기에 진행한 교양 IT 교과교육과정의 12개 교과목에서 2,322명 수강생들이 제출한 2,149건 강의평가 결과를 자료로 사용하였다. 강의평가 결과는 객관식 선택형 문항의 평가점수 외에도 주관식 서술형 문항도 학생들이 제출한 서술문을 긍정형과 부정형으로 분류하여 계량화를 하여 강의평가 결과를 객관화하였다. 연구 결과, 출석률과 학업성취도가 높을수록 강의만족도가 높았으며, 주관식 문항에서는 부정 단어보다는 긍정 단어를 더 많이 사용하였고, 학점이 낮을수록 부정 단어를 더 많이 사용하였다. 초급프로그래밍이나 소프트웨어활용군 과목군에서는 출석률이 높을수록 강의만족도가 높았지만, 중급프로그래밍에서는 출석률과 선택형 평가점수는 상관관계가 없었으며 주관식 문항에서도 타 과목군보다 부정 단어를 많이 사용하였다. IT 교과목에 대한 강의평가 경향은 일반 교과목의 강의평가 경향과 유사한 면도 있지만 중급프로그래밍 교과목에서는 대체로 부정적인 평가를 하는 것으로 나타났다.

The Leadership in Energy and Environmental Design (LEED) Green Building Rating System provides third-party verification for environmentally sustainable construction. But while LEED-certified buildings provide healthier work and living environments, Previous studies have shown that LEED certification does not provide any direct economic incentives to owners and developers. To address this issue, this study aims to investigate the economic benefits of LEED criteria. The objective of this study is to examine whether or not there is a significant correlation between median household income and the number of bus stops and light rail stations for a given parcel that meet LEED sustainable site criteria for public transportation access. The findings showed that the number of bus stops had a positive correlation with median household income, which means that more bus stops a given parcel had that met LEED criteria, the greater the median household income of a block group where the given parcel was located would be, though this positive correlation was very weak.

In this study, we investigated the effects of indole on biofilm formation inhibition in Pantoea agglomerans (P. agglomerans). In the biofilm growth assay, indole inhibited biofilm formation across all the growth time. Depending on biofilm growth stage, indole exhibited biofilm inhibition and anti-bacterial effects on planktonic cells. Through the analysis of the proportion rate between biofilm and Colony Forming Units (CFU) and inhibition rate of indole, we confirmed that depending on the biofilm stage of P. agglomerans, indole treatment timing was more important than the treatment duration. By comparing gene expression rates through rt-qPCR P.agglomerans affected by indole was found to significantly change quorum sensing (pagI/R) and indole transportation (bssS) gene expressions. Throughout all, indole exhibited both antimicrobial and anti-biofilm effects on P. agglomerans. In addition, we confirmed the anti-biofilm effects of indole on mature biofilm. In conclusion, indole as a signal molecule, can exhibit anti-biofilm effects through bacterial quorum sensing inhibition and indole affects. Therefore, indole can regulate biofilm bacteria especially gram-negative opportunistic pathogens.

This study analyzed trends in geoscientific research funding provided by the Korea Science and Engineering Foundation (KOSEF) and examined strategies to promote geoscientific research. The strengths of geoscientific research in South Korea include the excellent academic quality of researchers, established research infrastructure, and inter-disciplinary research. Weaknesses include insufficient leadership in related societies and institutes, insufficient research productivity, and the exclusion of the field from nationally supported large-scale research projects. Opportunities for expanded research include environmental issues, the sustainable use of natural resources, the promotion of international research cooperation, and the initiation of national efforts to find solutions for regional problems. However, growth in the geosciences is threatened by prioritized investment in fields such as biotechnology, nanoscience, and information technology, a dismissive attitude toward the growth of basic sciences, and an increased demand for projects with visible economic and societal impacts. In terms of funding, group-based programs receive more support than individual-based programs. Between 1978 and 2006, KOSEF invested 1,744 billion won ($1.873 billion US) in a total of 46,748 basic research projects. Of this amount, 62.1 billion won ($66.7 million US) was allocated to 1,901 projects in the geosciences, which was roughly 2.6-10.6% of the money available in a given year. These funds were used to support research and development, the development and maintenance of necessary infrastructure, and the education and training of geoscientists.

In this paper, we present a real-time physical simulation model of water surfaces with a novel method to represent the water mass flow in full three dimensions. In a physical simulation model, the state of the water surfaces is represented by a set of physical values, including height, velocity, and the gradient. The evolution of the velocity field in previous works is handled by a velocity solver based on the Navier-Stokes equations, which occurs as a result of the unevenness of the velocity propagation. In this paper, we integrate the principle of the mass conservation in a fluid of equilateral density to upgrade the height field from the unevenness, which in mathematical terms can be represented by the divergence operator. Thus the model generates waves induced by horizontal velocity, offering a simulation that puts forces added in all direction into account when calculating the values for height and velocity for the next frame. Other effects such as reflection off the boundaries, and interactions with floating objects are involved in our method. The implementation of our method demonstrates to run with fast speed scalable to real-time rates even for large simulation domains. Therefore, our model is appropriate for a real-time and large scale water surface simulation into which the animator wishes to visualize the global fluid flow as a main emphasis.

Reservoirs play a key role in the carbon cycle between terrestrial and marine systems and are pathways that release greenhouse gases(GHGs), CO₂, CH₄, and N₂O, into the atmosphere by decomposing organic matters. Developed countries have been actively conducting research on carbon emission assessment of dam reservoirs for over 10 years under the leadership of UNESCO/IHA, but associated research is very rare in Korea. In particular, the GHGs footprint evaluation, which calculates the change in net carbon emission considering the watershed environment between pre- and post- impoundment, is very important in evaluating the carbon emission of hydroelectric dams. The objective of this study was to estimate the GHG emissions and footprints in Daecheong Reservoir using the G-res Tool, an online platform developed by UNESCO/IHA. The G-res Tool estimates CO₂ and CH₄ emissions in consideration of diverse pathway fluxes of GHGs from the reservoir and characterizes changes in GHG fluxes over 100 years based on the expected lifetime of the dam. The input required to use the G-res Tool include data related to watersheds, reservoirs, and dams, and most were collected through the government's public portal. As a result of the study, the GHG footprint of Daecheong Reservoir was estimated to be 93 gCO₂eq/m²/yr, which is similar to that of other reservoirs around the world in the same climate zone. After impoundment, the CH₄ diffusion emission from the reservoir was 73 gCO₂eq/m²/yr, also similar to those of the overseas reservoirs, but the CH₄ bubbling emission, degassing emission, and CO₂ diffusion emissions were 44, 34, 252 gCO₂eq/m²/yr, respectively, showing a rather high tendency. Since the dam reservoir carbon footprint evaluation is essential for the Clean Development Mechanism evaluation of hydroelectric power generation, continuous research is needed in the future. In particular, experimental studies that can replace the emission factors obtained from the overseas dam reservoirs currently used in the G-res Tool should be promoted.
