최근 기상이변에 따른 이상홍수가 빈번하고, 댐 설계홍수량 설계기준이 가능최대홍수량(PMF)으로 강화되었으며, 최근의 주요 호우사상을 고려하여 산정한 임하댐 유역의 가능최대강수량(P.M.P)이 설계 당시보다 증가됨에 따라 가능최대홍수량(PMF) 유입시 댐 안정성 확보가 필요한 것으로 검토되었다. 따라서, 본 과업은 “댐의 수문학적 안정성검토 및 치수능력증대 기본계획 수립, 2004. 9. 건설교통부/한국수자원공사”에 의거하여, 최근의 태풍 ‘RUSA’(’02) 및 ‘MAEMI’(’03)와 같은 이상호우에 대한 댐 및 여수로의 안정성을 확보함으로써 국민의 생명과 재산을 보호할 수 있도록 비상여수로를 계획하였다. 비상여수로는 수문학적 안정성을 검토한 후, 가능최대홍수량(PMF)과 같은 홍수유입시 댐의 안전을 위하여 신속히 홍수를 배제시킬 수 있는 수리적.구조적인 안정성 확보가 가능하고, 시공성, 경제성 및 환경성 측면을 고려하여 댐우안 300m 지점에 터널규모 D15m${\times}$3련 ${\times}$L1,262m (L1=379m, L2=421m, L3=462m)의 월류형 터널식으로 계획하였다.

이진상(李震相)의 춘추학(春秋學)에 보이는 화이관(華夷觀)의 특징

김동민 ( Kim¸ Dong-min ) 한국철학사연구회 2020 한국 철학논집 Vol.0 No.67

본 논문은 이진상의 『춘추』 ‘화이(華夷)’와 관련된 해석을 분석하고, 그 특징을 밝히는 것을 목적으로 한다. 선행 연구에서는 『춘추』 화이(華夷) 관념의 이론적 원칙을 주제로 삼아서, 중화(中華)와 이적(夷狄)의 분별과 그로 인해 형성된 이적에 대한 배타성을 연구하였다. 본 논문은 화이 관념의 현실적 변용이라는 주제로 진행한 후속 작업이다. 세부적으로는 화이(華夷) 관계의 현실적 재정립, 이적(夷狄)의 중화(中華) 진입과 패자(霸者)로서의 역할을 논의의 대상으로 삼았다. 먼저, 『춘추』의 화이관념은 이론적인 원칙과 기준을 세웠지만, 현실적인 측면에 중화와 이적의 분별이 무너지고, 중화 내부의 심각한 이적 행위가 발생하였다. 이러한 중국의 현실을 분석하고, 그것을 바탕으로 재정립된 『춘추』의 현실적 화이 관계를 탐색하였다. 다음으로 중화의 이적화(夷狄化)로 인해천하의 혼란은 더욱 가중되었지만, 중화의 패자는 혼란을 바로잡을 수 있는 능력을 이미 상실한 상태였다. 이와 같이 중화의 패자가 부재한 상황에서, 초(楚)나라 등의 강력한 이적 집단이 중화와의 교류를 통해 중화의 일원으로 진입되는 과정, 그리고 중화의 패자로서 이적의 역할 등을 탐색하였다. This article analyzes Lee Jin-Sang's interpretation related to "Sino-barbarian dichotomy" in the Spring and Autumn Annals and reveals its characteristics. The preceding study examined the distinction between Chinese and the barbarians and its consequent exclusion of the barbarians based on the theoretical principle of Sino-barbarian dichotomy in the Spring and Autumn Annals. This paper focuses on a transformation of the idea of Sino-barbarian distinction when applied in reality. A re-establishment of the relationship between Chinese and barbarians in the real-world, the entry of the barbarians into China, and their role as the dominant (霸者) are discussed. Though the idea on Sino-barbarian distinction in the Spring and Autumn Annals contributed to establishing theoretical principles and standards, the distinction failed in reality and the Chinese witnessed barbarian incidents that occurred within China. The paper analyzes the reality of China and then explores the newly established, more realistic relationship between Chinese and barbarians. The chaos intensified because of Chinese-turn-into-Barbarians, but the dominant that can bring order into this chaos was absent among the Chinese. In an absence of the dominant inside China, powerful groups of barbarians, such as Cho (楚) state, entered into China through exchanges with Chinese and became a member of China. This paper studies the process of the changes and their role as the dominant.

Recently, as interest in non-face-to-face experiences and services increases, the demand for web video contents that can be easily consumed using mobile devices such as smartphones or tablets is rapidly increasing. To cope with these requirements, in this paper we propose a technique to efficiently produce video contents that can provide experience of visiting famous places (i.e., stage tour) in animation or movies. To this end, an image dataset was established by collecting images of stage areas using Google Maps and Google Street View APIs. Afterwards, a deep learning-based style transfer method to apply the unique style of animation videos to the collected street view images and generate the video contents from the style-transferred images was presented. Finally, we showed that the proposed method could produce more interesting stage-tour video contents through various experiments.

농업용 저수지의 점오염원 바이패스 효과 평가를 위한 EFDC 모델의 적용

Agricultural reservoirs in Korea have been recognized as an emerging resource for recreational and cultural activities for residents. However, most of the reservoirs are eutrophic and showing high level of contamination with nuisance algal bloom and offensive odor during the summer. For better management and restoration of the reservoirs' water quality, scientific modeling approaches could be used to diagnose the problems and evaluate the efficacy of alternative control measures. The objectives of this study were to validate the performance of a three-dimensional (3D) hydrodynamic and water quality model (Environmental Fluid Dynamics Code, EFDC) for a eutrophic agricultural reservoir and assess the effect of bypassing of the effluent from a wastewater treatment plant on the reservoir water quality. The 3D model successfully simulated the temporal variations of water temperature, DO, TOC, nitrogen and phosphorus species and Chl-a observed in 2014 and also captured their spatial heterogeneity in the reservoir. The simulation results indicated that the point source bypassing may reduce the T-N and T-P concentrations of the reservoir by 6.6 ~ 8.2 %, and 1.7 ~ 16.8 %, respectively. The bypassing, however, showed a marginal effect on the control of TOC due to the increased algal biomass associated with the increased water retention time after bypassing as well as the lower TOC level of the effluent compared to the ambient reservoir water.

The aim of this work was to investigate the cellular responses and proteomic analysis of Bacillus cereus MH-2 exposed to EGCG. Strain MH-2 was isolated from commercial Ssamjang and has the hemolytic activity. Survival of the MH-2 strain with time in the presence of different concentrations of EGCG under sublethal conditions was monitored. The amount of alginate from MH-2 strain decreased depending on the increasing concentrations of EGCG and increased depending on the exposure time at any particular EGCG concentration. Analysis of SDS-PAGE and Western blot using anti-DnaK and anti-GroEL revealed that two stress shock proteins, 70 kDa DnaK and 60 kDa GroEL were found to decrease in proportion to the EGCG concentration in exponentially growing cultures. Scanning electron microscopic analysis demonstrated the presence of protrusions and fused rod forms on the cells treated with EGCG. 2-DE of soluble protein fractions from MH-2 cultures showed 20 protein spots changed by EGCG exposure. These proteins involved in enterotoxins (hemolysin BL lytic component L1 and hemolysin BL-binding protein), chaperons (DnaK and GroEL), cell defense (peptidase M4 family proteins), and various biosynthesis and energy metabolism were identified by peptide mass fingerprinting using MALDI-TOF. These results provide clues for understanding the mechanism of EGCG-induced stress and cytotoxicity on B. cereus MH-2.

The engine oil life of internal combustion engine is shorted by the thermal effect and that causes air pollution. In order to measure the status of engine oil accurately, the exchange of new oil extends the life of combustion engine and reduces environmental pollution. Capacitance probes, such as engine oil and fluids can be used to measure the dielectric constant. In this paper, the degradation of engine oil varies depending on the degree of dielectric properties was analyzed. Depending on the state of the oil, the variant capacitance of the probe was measured by LCR Meter, respectively, and then the permittivity of oil was calculated. In addition, according to the size of the probe by measuring the change in capacitance measurement, accuracy of dielectric constant are presented. According to oil contaminated with the more increase in dielectric constant, we can decide that contaminated oil is available.
