This paper introduces an Expert System Auditing Quality Management System for Construction(AQM) which assess the performance of a Quality Management System(QMS) implemented in a construction firm. It assess the effectiveness and the confirmity level of QMS and diagnoses the nonconformity of an existing component of the QMS compared to the ISO 9000 QMS’s 20 components. The expert rule bases is constructed with the facts and rules obtained from the ISO 9000 standards. The system integrates the requirements of ISO 9000 QMS, clarifies the results of quality audits, reduce the variation between different human quality system auditors, and facilitates to make a consistent decision making involved in quality audit. It provides quality auditor with an interactive user interface, an explanation module for reasoning its conclusions, and an assisting module for understanding a specific assessment requirement. AQM contribute to the field of construction quality management, specifically to continuous quality improvement because it (1) increases the maintainability of a quality management system by making the quantification of quality performance possible, (2) fills in the gap in the construction community as a quality management system assessor, (3) increases the usability of the historical quality audit records, (3) simplifies the tedious and burdensome process involved in keeping track the progress of quality audit and in recording the audit results of the many requirements, (4) effectively handles the variability of the quality audit results attributed by different human quality system auditors. Therefore it contributes to make more rigorous quality audits and continuous quality improvement. The section entitled to "Control of inspection, measuring and test equipment", which is the 4.11 requirements of the ISO 9000 QMS, is used as a case to illustrate the system and its functions. It is implemented as an easy-to-use computerized tool programmed in MATLAB.

용매 어닐링에 의한 박막에서 Polystyrene-Poly(1,4-butadiene) 블록공중합체의 모폴로지 전이

이동은(Dong Eun Lee),김응건(Eung Gun Kim),이동현(Dong Hyun Lee) 한국고분자학회 2012 폴리머 Vol.36 No.4

본 연구에서는 용매 증기 하에서 박막으로 제조된 polystyrene-poly(1,4-butadiene) 블록공중합체(PS-b-PBD)의 모폴로지 형성과 특성이 원자주사현미경(AFM)을 사용하여 연구되었다. 사이클로헥산으로만 용매 어닐링된 박막의 경우 폴리스티렌의 매트릭스 내부에 PBD가 미세상을 형성하는 perforated lamellae가 형성되었지만, n-헥산만으로 용매 어닐링 된 박막은 불규칙한 패턴만이 관측되었다. 그러나 사이클로헥산과 n-헥산의 혼합 용매를 사용하여 용 매 어닐링할 경우 기질에 수직으로 배향된 라멜라가 관측되었다. 이러한 모폴로지 전이는 혼합 용매의 혼합비에 의 해 조절되며 n-헥산의 양이 증가하면서 라멜라의 형성이 뚜렷이 관측되었다. 그러나 용매 어닐링에 사용된 혼합 용 매 중 n-헥산의 주요 성분이 될 경우 n-헥산의 PBD로의 용매 친화력에 의해 모폴로지 형성이 오히려 지연되는 것을 확인하였다. 이러한 사이클로헥산과 n-헥산의 혼합비에 따른 모폴로지 전이는 블록공중합체에 대한 두 용매들의 친화력과 관련 있으며, 이를 이해하기 위해 이들의 용해도 상수 및 Flory 상호인력 인자들이 고려되었다. 또한 본 연구로부터 얻어진 두 가지 모폴로지를 이용하여 실리카 나노 패턴의 제조를 위한 템플레이트로 활용하였다. Morphological characteristics and formation of symmetric polystyrene-block-poly (1,4-butadiene) copolymer (PS-b-PBD) in thin films upon solvent-annealing were investigated by using atomic force microscopy (AFM). The thin films solvent-annealed in cyclohexane revealed the perforated lamellae of poly (1,4-butadiene) in the matrix of polystyrene while those solvent-annealed in n-hexane exhibited highly disordered patterns. Interestingly, when the thin films of PS-b-PBD were solvent-annealed with binary mixtures of cyclohexane and n-hexane, the morphological transition from the perforated lameallae to the perpendicularly-oriented lamellae of poly(1,4-butadiene) could be induced by changing the mixing ratio of both solvents. We also demonstrated that after microdomians of poly (1, 4-butadiene) were successfully degraded by UV-O3, linear poly (dimethyl siloxane) chains were back-filled into the etched regions of the thin film and then converted to silica nano-objects by oxygen plasma treatments.

시뮬레이션 일정관리-최종공사기간의 비정규분포 특성 검증

이동은(Lee Dong-Eun) 대한건축학회 2008 大韓建築學會論文集 : 構造系 Vol.24 No.4

Existing PERT and simulation based scheduling methods have been based on the assumption that the simulation output data, Project Completion Times (PCTs), follow normal distribution. However, this paper verifies that the normality assumption of Distribution of PCTs in Simulation based Scheduling is not always acceptable and the existing belief may lead to misleading results. The assumption has been well accepted in construction scheduling community. However, substituting the quantification method that measures the effect caused by the assumption may improve the reliability of the simulation method. This paper presents a risk quantification method relative to the probability distribution of PCTs. The method is implemented as an algorithm in MATLAB. Several series of simulation experiments have been carried out to analyze a set of simulation output data which are obtained from different type of Probability Distribution Function (PDF) assigned to activities’duration in a network. The method facilitates to find the effect of PDF type and its parameters. This article describes the procedure necessary for performing the risk quantification method along with the findings. This paper contributes to improving the reliability of simulation based scheduling method, as well as increasing the accuracy of analysis results.

한국어 구어 담화 연구를 위한 전사와 주석에 대한 논의

이동은(Dong-Eun Lee) 사단법인 한국언어학회 2016 언어학 Vol.0 No.74

This paper discusses the current transcription system that has been used to transcribe oral discourse of Korean language, and a proposal for a gloss system that will further improve the discourse analysis. Since the 1990’s, in depth research on the areas of discourse analysis, especially on the specific characteristics of Korean discourse, became more active. And since the start of the 21st century, Korean educational academia has been actively doing analytical research on the oral discourse with subjects being Korean native speakers and the non-native learners. More recently, by utilizing the previous results, large scale of basic research and establishment on spoken corpus is in progress. In our research, we looked into the reality of transcriptive notation in both domestic and foreign dissertation, as well as, papers published in academic journal and research project papers, to check and discuss the correlation with the research theme. As a result, we found that there were many cases that followed a similar version used by the English linguistics, where cases of simplified transcriptive notation are used to correlate with the purpose of the research, the method, and the relevancy to the result. Following the result, we turn the focus on contributing to making proper Korean Discourse Gloss system by introducing the research being done by the International Standard Organization. These types of discussion will not only contribute to the further advance in research on multi-dimensional and yet more dynamic meaning of the discourse, it will also be a groundbreaking effort to promote international knowledge of the Korean educational linguistics by making the transcription of the discourse more logical and improving the Gloss system, as well as, establishing the spoken corpus for students of the Korean language.

한국어 학습자 구어 말뭉치의 담화 분석적 논의

이동은(Lee Dong-eun),김지애(Kim Jiae) 한글학회 2016 한글 Vol.- No.313

이 글은 한국어 구어 담화 연구에 적용하기 위한 대화 행위의 주석체계를 논의하는 데 그 목적을 둔다. 형태와 통사 주석은 마련된 것이 있지만 담화 차원에서의 주석 체계에 대해서는 아직까지 명확한 기준을 제시한 연구가 부재하기에 본 연구에서는 한국어 학습자 말뭉치 구축에 있어서 담화 차원의 대화 행위 주석 체계를 실험적으로 모색해 보고자 한다. 아울러 대화 행위 주석 체계 정립의 가능성을 타진하고 주석 작업의 신뢰도를 높이기 위한 단계적 절차 수행 방안에 대해 논의한다. 그리고 대화 행위 주석이 실제로 어떠한 연구로 활용될 수 있는지 보이기 위해 주석이 부착된 자료를 활용하여 일상대화에서의 담화 전개 양상을 분석해 보이고 그것이 한국어 담화 교육에서 어떻게 적용될 수 있는지 논의한다. 합리적 차원의 대화 행위 주석 체제를 마련하는 것은 다차원적이고도 역동적인 담화 의미를 규명하기 위한 출발점이 된다. 또한 학습자 구어 말뭉치의 구축 과정에 이를 적용함으로써 교수 · 학습과 교재 및 교육 자료 개발에 기여함은 물론 국제 학계에서 한국어 담화 분석과 한국어교육학의 효율적 소통을 기대할 수 있을 것이다. This paper focuses on discussing the dialogue act annotation system that can be applied when studying about Korean oral discourse. Since 1990’s, in the field of discourse analysis, an objective research on investigating the characteristics of Korean oral discourse, started to take place. And since the start of the 21st century, Korean language teaching academia began to actively do analytical research on the oral discourse of Korean language learners. More recently, At a national level, a task of establishing and utilizing Korean language learners’ corpus is in progress. In order for a large national corpus research to be applied continuously in future researches, developing a annotation system that can effectively handle spontaneous information is necessary. Even though there are forms and syntax annotation system that are already developed, we still lack researches that clearly defined the standard for a annotation system at a discourse level. Therefore, this research seek to develop a dialogue act annotation system at a discourse level through experiments. The foundational theories that helped develop a reasonable Korean dialogue act annotation system were the various researches done by different corpus language departments, but the main reference that was used was the results of research and development by ISO. In first experiment, we provided 14 tags and requested 2 inexperienced taggers to do a trial conversation. Using the problems and implications as base, we added an additional tag and performed the second trial using 15 tags. To increase the credibility on the second experiment, we broke down each stage of the trial. First, the taggers performed their own test. Second, they cross examined each others results and finally gave chance to discuss and revise the results together. If the taggers cannot come to an agreement, one of the skilled researchers will listen to the sound file and judge the final tag. Through the experimental process, we were able to further examine the possibility of establishing a dialogue act annotation system, and discuss ways to increase the credibility by separating each part of the experiment stages. And to find out how dialogue act annotation can be utilized in other experiments, we applied the materials that includes the tags to daily conversation and analyzed the developing aspect of conversation. Using the result of the analysis, we further examined how it can be applied to teaching Korean discourse. Establishing a rational dialogue act annotation system is a starting point to deeply understanding the multi-dimensional and yet more dynamic meaning of the corpus. Also, by utilizing the information when establishing learner’s oral corpus, it will not only contribute to developing teacher and student learning materials, but can also expect more efficient communication on analytical Korean discourse and Korean linguistic education at international academia.

국제기후변화법제와 국제통상법체제의 조화적 공존을 위한 법적고찰 : 탄소배출권 무상할당조치와 WTO 보조금협정을 중심으로

이동은(Dong-eun LEE) 서울국제법연구원 2020 서울국제법연구 Vol.27 No.2

2015년 12월 파리협정이 채택됨에 따라 교토의정서 체제를 대체하는 신기후체제가 도입되었다. 이에 따라 탄소배출에 가격을 부여하여 온실가스 배출비용을 부담하도록 하는 소위 탄소가격제(carbon pricing)의 시행이 점차 확대되어 가고 있으며, 여러 국가들은 온실가스 감축을 위한 주요 수단으로서 배출권 거래제의 시행을 확대해가고 있다. 최근 미국의 철강업체들은 유럽 및 한국의 탄소배출권 거래제를 보조금의 측면에서 문제 삼고 있으며, 특히 탄소배출권 무상할당이 상계관세 부과의 대상이 되는 보조금이라고 주장하고 있다. 보조금은 무역 및 경쟁에 왜곡을 초래할 수도 있으나 시장실패 방지 또는 다른 합법적 정책목표를 추구하는데 이용된다는 측면에서 양면적 속성을 지닌다. 그런데 ASCM은 환경정책 측면에 입각한 정당화 가능성을 인정하지 아니하고 협정의 기계적 적용결과에 따라 보조금 여하를 판단하도록 하는 내재적 한계가 있다. 탄소배출권 무상할당조치는 각국의 불균형적인 환경규제정책에 따라 발생하는 탄소누출의 문제를 방지하기 위한 주요 수단이다. 보조금 논리에 의해 탄소배출권 무상할당이 불가능하게 된다면 기후변화법제상 의무 준수가 어려워 질 수도 있다. 탄소배출권 무상할당조치를 보조금 협정 규율에 비추어 검토하고, 국제기후변화법제와 국제통상법체제가 조화적으로 공존할 수 있는 방안을 모색하여야 한다. With the adoption of the Paris Agreement in December 2015, the global governance of greenhouse gas emissions has been shifted from the Kyoto Protocol regime to the post-Paris new climate regime under which state parties are required to put their efforts to combat climate change by establishing voluntary goals to reduce carbon emissions. Carbon pricing mechanisms which put an explicit price on GHG emissions are gradually expanded in the countries, and emissions trading system is one of the major options chosen by states for their reduction of greenhouse gas emissions. However, the emissions trading system has recently been called into question by the US steel companies in context of subsidies disciplines. Specifically, the free allocation of emission allowances is claimed as conferring subsidies subject to countervailing duties. Given their ambivalent characteristics, subsidies are often accused of incurring trade distortion, but some of them are required as legitimate policy tools for the governments to prevent the market from failure. WTO subsidies disciplines, however, do not allow justifications for legitimate governmental policies including environmental purposes, but they rather evaluate measures as subsidies by solely relying on mechanical rules in the WTO subsidy agreement. Studies have proven that the free allocation of emission allowances is one of the most effective means to prevent carbon leakages which are caused by imbalances between states’ environmental regulations. If states are prohibited to provide free allowances because of the logic of subsidies, they will lose one of the efficient tools to satisfy their obligations under the international climate change regime. In this regard, the author will review the free allocation of emission allowances in context of WTO subsidy agreement, and suggest a probable way for a harmonic coexistence of the international climate change regime and the international trade law regime represented by the WTO.
