Voltage transformers (VTs) must be highly reliable as they are essential components of the electric power industry. VT failures can cause a signifcant impact for important facilities such as nuclear power plants. In fact, VTs which passed the international standard, were damaged and sometimes resulted in the shutdown of the nuclear power plants. In order to improve the reliability, VTs with various iron core was studied. The electromagnetic feld simulation, a saturation characteristics test, and an overvoltage breakdown test were conducted. The result shows that the magnetic fux density signifcantly afects the reliability of VTs. To increase the reliability of VTs, it is required to reduce the magnetic fux density by increasing the knee-point and voltage factor. Owing to limited installation space, increasing the size of the iron core is difcult. Instead, VT by decreasing the thickness of the conductor and increasing the number of turns, it was possible to reduce the magnetic fux density without the size change. Therefore, improved VTs were obtained by decreasing the thickness of the conductor and increasing the number of turns, and the improved reliability was verifed through a comparison test with existing VTs. The fabricated VTs shows a signifcantly higher saturation voltage and breakdown time than existing VTs. Thus, by proposed VTs can contribute the stable operation of the nuclear power plant and improve the manufacturer’s quality.

Influence of Al2O3 Content and Cooling Rate on Crystallization in Fe2O3–CaO–SiO2–Al2O3 Systems

Tae Jun Park,Joon Sung Choi,Dong Joon Min 대한금속·재료학회 2022 METALS AND MATERIALS International Vol.28 No.9

The behavior of silico-ferrite of calcium and aluminum (SFCA) phases and the influence of sintered ore quality were investigatedusing a confocal laser scanning microscope to understand how the Al2O3content of iron ore affects the sintered orestructure and the crystallization behavior of SFCA in a Fe2O3–CaO–Al2O3–SiO2 pseudo-quaternary system. The experimentalresults were used to inform simulations of the heterogeneous dynamic behavior in response to the rapid temperature changesand various chemical compositions typically encountered in actual sintering processes. Increasing the Al2O3content in theFe2O3–CaO–Al2O3–SiO2 pseudo-quaternary system led to the hematite content decreasing, which affects the reducibilityof the sintered ore. The correlation between the creation of SFCA and the cooling effect associated with varying the Al2O3is discussed in detail.

Dong‑Jun Lee,Taesoo Kwon,Chang‑Kug Kim,Young‑Joo Seol,Dong‑Suk Park,Tae‑Ho Lee,Byung‑Ohg Ahn 한국유전학회 2020 Genes & Genomics Vol.42 No.11

Background Sequence variations such as single nucleotide polymorphisms are markers for genetic diseases and breeding. Therefore, identifying sequence variations is one of the main objectives of several genome projects. Although most genomeproject consortiums provide standard operation procedures for sequence variation detection methods, there may be differencesin the results because of human selection or error. Objective To standardize the procedure for sequence variation detection and help researchers who are not formally trainedin bioinformatics, we developed the NGS_SNPAnalyzer, a desktop software and fully automated graphical pipeline. Methods The NGS_SNPAnalyzer is implemented using JavaFX (version 1.8); therefore, it is not limited to any operatingsystem (OS). The tools employed in the NGS_SNPAnalyzer were compiled on Microsoft Windows (version 7, 10) andUbuntu Linux (version 16.04, 17.0.4). Results The NGS_SNPAnalyzer not only includes the functionalities for variant calling and annotation but also providesquality control, mapping, and filtering details to support all procedures from next-generation sequencing (NGS) data to variantvisualization. It can be executed using pre-set pipelines and options and customized via user-specified options. Additionally,the NGS_SNPAnalyzer provides a user-friendly graphical interface and can be installed on any OS that supports JAVA. Conclusions Although there are several pipelines and visualization tools available for NGS data analysis, we developedthe NGS_SNPAnalyzer to provide the user with an easy-to-use interface. The benchmark test results indicate that theNGS_SNPAnayzer achieves better performance than other open source tools.

조르주 바타유의 비정형 개념을 통한 물의 디지털이미지 정형화 연구

염동철 ( Dong Cheol Yoem ),오태원 ( Tae Won Oh ) 한국기초조형학회 2015 기초조형학연구 Vol.16 No.1

본 연구는 조르주 바타유의 ‘비정형’ 개념을 디지털이미지에 도입해 물이라는 소재가 정형화될 수 있는지 그 가능성과 작품사례를 통해 분석해 본 연구이다. 논리적 근거를 제시하기 이전에 바타유 사상의 기저가 되는 유물론과 거기에서 연결되는 비정형의 작동기제 중 ‘저급유물론’과 ‘엔트로피’의 속성을 바타유의 비정형 개념으로 타진해 보았다. 바타유의 비정형 개념은 부아와 크라우스의 「비정형: 사용자 안내서」에 수록된 내용과 크라우스의 해석, 그리고 바타유의 철학적 사유와 함께 분석해 보았으며, 바타유에 의하면 비정형이란 현실을 추상적 개념들에 따라 재조직하고 작은 의미의 단위들로 분해하는 범주들과 형태적 경계들을 파기해버리는 것이며, ‘의미 없는 비개념’이 곧 비정형이다. 따라서 비정형은 스스로는 아무 의미도 갖지 않으면서 기존하는 형태들이 지닌 의미들, 형식적 범주들의 작동을 와해시키는 ``임무``만을 가진 개념이다. 그러한 분석으로 비정형 개념은 디지털이미지와 자연스럽게 연결되고 구동될 수 있는 개념이다. 이러한 비정형의 물은 정형의 대상이 아니므로 디지털매체를 통해 정형화될 수 있는 소지를 내포하고 있는 소재이며, 디지털이미지작업을 통해 독창적인 형태를 구현할 수 있다. 그 예로 작품분석을 통해 각각 획득하고자 하는 이미지를 위해 일련의 설정된 환경과 정형화된 도구들을 수용하였음을 알 수 있었으며, 오태원의 미리 계획된 실험을 통해 투명한 수조와 LED조명이라는 정형화된 도구 사용이 물의 디지털이미지 형태를 훨씬 선명하게 하며 물 이미지를 더욱 부각 시킬 수 있었음을 알 수 있었다. 이 연구가 기존의 디지털 아트 작업을 통한 이미지는 유동적, 가변적, 비정형적일 것이라는 관념을 깨고 오히려 비정형의 매체를 통해서 비정형의 소재가 정형화된 형태를 구축할 수 있다는 새로운 패러다임을 제시한다. A Study on Digital Image Formalism of Water Through the Formless Concept of Georges Bataille This study aims to analyze the possibility of applying the ``formless`` concept of Georges Bataille to digital images and formalizing water as a material, based on the cases of related works. Prior to presenting a logical basis, materialism, which is a base of Bataille thoughts, and the properties of ``base materialism`` and ``entropy`` out of the formless mechanisms connected with materialism were considered as formless concepts. Bataille``s formless concept was analyzed along with the concepts included in the 「Formless: A User’s Guide」 written by Bois and Krauss, Krauss``s interpretation and Bataille``s philosophic thoughts. According to Bataille, ``formless`` is to re-organize the reality depending on abstract concepts and to destroy the categories and morphological boundaries subdivided into small semantic units, and ``meanless non-concept`` is exactly formless. Thus, formless does not have any meaning itself and its concept only performs the ``duty`` to collapse the meanings of the existing forms and the operation of formal categories. Based on that analysis, the formless concept can be naturally interlinked with digital images and operated. In other words. This formless water is not subject to formalism and thus this contains the possibility of being formalized through digital media and can create its own unique form through digital imaging. As an example, it was found that for images to obtain, individual works accepted a series of set environments and standardized tools, and Oh, Tae-won``s previously planned experiment showed that using the standardized tools like transparent water tank and LED lighting could make the digital image of water much clearer, or emphasize the image of water more. In conclusion, this study breaks the idea that digital art images would be fluid, variable and formless and presents a new paradigm that formless materials can create formalized forms through formless media.

이태정,김동술,전준민 경희대학교 2006 環境硏究 論文集 Vol.15 No.-

The Jeongja housing development complex located in the northern Suwon city consists of around 30,000 households in a large scale apartment complex including 18,000 households near the Chitin Area. Since the apartment complex had been constructed near the existing chemistry and the medical and drug manufacturing factories, many public nuisances/grievances caused by malodorous smell were appealed by residents. For example, a total of 26 public nuisances against malodorous problems was recorded only in the year of 2005. Thus, the objective of the study is to intensively identify the odor causing chemical species and sources to deal with public nuisances, to prepare substantial management plans, and finally to attain pleasant air environment inside the study area. The odorous matters have been sampled 2 times at the following sites; near boundary areas between residential area and factory, public nuisance areas, and a background area. The highest dilution multiple factor was 17.5 on an average at the site, b2; however, it was below the emission standard of 20. The resulting factor at the site, al, was higher than the other sites, but the result did not exceed the emission standard The elevated ammonia concentration was observed at the sites near boundary areas of the Sinmyoung apartment, where located on the downward direction from the factory. The levels (112.7 pp. during the 1st survey and 81.9 pp. during the 2nd survey) were 2 to 3 times higher than the other sites.
