Distribution basins are used widely in the water treatment process. Uniform distribution at the distribution basin is an important because it affect precipitation efficiency of sedimentation basin. Generally distribution basin has a free surface water and is consisted of a weir. Study result, when inflow of distribution basin is less, amount of overflow is much at the nearest weir from the inlet. But when inflow is much, amount of overflow is much at the far weir from the inlet. The difference of distribution amount at the pipe is affected by the curvature and length of the pipe. The magnitude of the effect is determined by the relative energy loss and the flow state of the distribution basin. Optimization of the response surface method for minimizing an amount of deviation of the distribution is a very useful technique to determine the optimal ratio of the valve opening.

국내 상하수도 시설들은 운전과 관리 인력의 노후화와 같은 유지관리의 어려움이 가속화되고 있으므로 디지털트윈 기술이 유력한 관리 기술로 부각되고 있다. 국내 정수장의 디지털트윈 기술은 환경부의 지능형 하수처리, 일부 지자체에서독자적으로 진행되는 사업 및 K-water 주관의 디지털 트윈 과제 등이 포함되지만, 적용 범위가 각 기관별로 상이하다. 이에 따라 정수공정에서는 시행착오를 줄이고, 미래 사업 활성화를 위해서는 기술표준화와 순차적 도입과정이 필요하다. 본 연구의 목적은 환경부 스마트하수처리사업, K-water 지능형정수공정 구현사업, 지자체 사업 등 각 기관별로 추진되고있는 디지털트윈 관련 기술에 대한 효율적인 추진 전략을 제공하는데 있다. Domestic water supply and sewage facilities are rapidly aging and maintenance difficulties such as aging of operation and management personnel are overlapping, so Digital Twin technology is attracting attention as an intelligent means of process management. Digital twin projects for domestic water treatment processes include the smart sewage treatment project promoted by the Ministry of Environment, projects independently promoted by some local governments, and digital twin purification plant projects promoted by K-water. However, the content of digital twin promotion is different for each institution. Therefore, in the water treatment process, technological standardization and step-by-step implementation methods for digital twins must be preceded to reduce trial and error in future business promotion. This study aims to provide an efficient promotion plan by prescribing the digital twin element technology and composition method in the water treatment process and reviewing the contents currently being promoted by the Ministry of Environment, local governments, and K-Water individually.

Post-chlorination for disinfection in portable water process is final process. The design factors of post-chlorination are inflow pipe line from tank of filtrated water to cleanwell, injection point of chlorine, appropriate shape of baffle in cleanwell for disinfection efficient improvement. Until now, we did not have the design standard for post-chlorination. we evaluated most suitable design method of post-chlorination process in portable water process by using computational fluid dynamics in this research. We found the result that the pipe to connect the cleanwell should be one. If pipe line split into two or more, uniform distribution of the flow is difficult. Second, optimal injection point of chlorine is the middle of pipe line to connect the cleanwell. Therefore, it is not economical to install chlorine contact basin in cleanwell. Third, the shape of baffle should be designed in order to water flows in one direction. And we found that it is better to design the low number of flow turning.

『한눈팔기(道草)』에 나타난 소세키의 자본주의 인식의 한 측면에 관한 연구

This study examined a money matter on Soseki"s literary works by focusing on his capitalistic perception. Without exception, there were money matters entwined between the characters" relationships. Also, he raised a question about the dominance on money and negotiability which is one of the importance aspects in a capitalistic society. Especially I will study an aspect of his perception about capitalism by examining『Mich Kusa』 which dealt a money matter in Soseki"s personal life. In『Mich Kusa』, Soseki was continuously drawing a drama which his money matter was entwined with Kenjo"s past and his relationships. As around 10 years passed, it is confirmed that Soseki"s reflective feelings were turned into negative perspectives about money through Kenjo, the main character. What Soseki wrote in『Mich Kusa』 didn"t investigate the structure which the privileged class exploited other classes. He also didn"t write about human"s behavior that a person does something evil because of lack of money. Soseki wrote about the reality how humans degrade themselves as they arouse desires for money. Soseki assumed that a person who degrades his dignity by being tempted by money (especially Simada) cannot be refined through education or courtesy since that is the person"s nature. Soseki is thought that he wrote『Mich Kusa』 to reflect his past. While he was writing, he realized he could not mention about his past not mentioning about relationships entwined with money. In addition, he depicted the reality that the dominance on money can affect a person"s live. It was his intention to reveal the reality of human"s life. In his work said Kenjo "Everyone wants money and no one wants anything else except money.” Soseki expressed his strong discontent in Kenjo"s statement that a human who wants money more than spirit but stolen without anything spiritually. This is nothing but he perceived the dominance on money and negotiability which is one of the characteristics of capitalism.

The railway distribution system consists of the high-voltage consumers to supply drive power to vehiclesthrough power feeder lines and low-voltage consumers for station heat transfer, air conditioning, and control systems. Elec-trical facilities and MCCBs are installed with products that have passed tests according to the requirements of related stan-dards before installation, but there is a lack of references for performance degradation and maintenance during use. Also, replacement cycle is managed according to electrical safety standards. Therefore, in this paper, changes in interruption per-formance according to inflow number of over-currents flowing into MCCBs used in railway electrical facilities is analyzed. When divided into three parts according to operation in terms of short circuit performance before current zero point of cir-cuit breaker, the time for extinguishing the arc in the splitter plate decreased as the number of inflows increased. It was also confirmed that the time to form an arc between contacts inside the arc extinguishing room increased. These experimental results are expected to be used as reference data for changes in interruption performance during use of MCCBs and for practical maintenance and life evaluation.

시민문학, 민족문학, 세계문학

본고는 최근 논의되고 있는 ‘세계문학론’의 대표적 이론가인 백낙청의 세계문학론을 그의 초기 대표평론으로 간주되는 「시민문학론」으로부터 음미해보려는 시도이다. 1969년에 발표된 「시민문학론」은 같은 해 발표된 김주연의 「새시대 문학의 성립」에 대한 응답으로서 씌어진 글로, 소위 ‘시민-소시민 논쟁’의 핵심적인 문헌 중 하나이다. 하지만 정작 이 글이 의미있는 것은 ‘시민(의식)’, ‘소시민(의식)’과 문학의 관계에 대한 인식을 심화시켰다는 데에 있다기보다는 과거의 문학 (즉 50년대까지의 문학)과 당대문학(60년대 문학)을 어떻게 평가하는지를 둘러싸고 첨예하게 대립한 서로 다른 문학적 입장에 있었다. 왜냐하면 이후 그것은 소위 ‘창비’와 ‘문지’라는 양대 문학진영의 문학관과 근본적으로 맞닿아있기 때문이다. 그런데 「시민문학론」은 이런 논쟁적 맥락과는 별개로 ‘백낙청 비평의 원형적 형태’를 보여주고 있다는 측면에서 접근할 수 있는데, 이 글에서 취해진 문학적 입장이 40년이 넘는 세월 동안 큰 변화 없이 지속되어 왔다는 점을 감안할 때, 그것은 선택이 아닌 필수라 하겠다. 따라서 본고는 「시민문학론」에서 확립된 그의 입장이 어떠한 형태로 오늘날에까지 이르고 있는지를 개략적으로 살펴보고, 그러한 문학관이 오늘날 한국에서 이야기되는 ‘세계문학’ 논의에 어떻게 참여하고 있는지, 또 그랬을 때 직면하는 문제가 무엇인지를 간단히 짚어보았다.
