계획 합리성 측면에서 본 지방정부 간 갈등 연구: 지방자치제로 인한 국가공간 변화를 중심으로

김동완 국토연구원 2009 국토연구 Vol.62 No.-

This paper examines intergovernmental conflict in the regard of Weberian planning rationality, the foundation logic of modern national-state. Since studies on intergovernmental conflict have focused only on organizational relationship, those have limitation of understanding the conflicts simply as to the level of institutional fix or leadership. This paper proposes that intergovernmental conflict with elected officials is resulted by spatial differentiation in the state rationality, not by just the purely organizational relationship of government. In this paper, Weber's state theory and the notion of rationality are modified with the notion of state space and scale. Also, the meaning of local autonomy was examined by historical method, regarding the spatial differentiation of substantive rationality as the core concept of the analysis. The result is as the following. Firstly, South Korean developmental state had huge substantive rationality as “Fatherland modernization” in national scale. However, the local autonomy had based on the success of democratization and industrialization has leaded substantive rationality to spatially differentiate. Finally, the intergovernmental conflict can be the conflicts among the substantive rationalities. 본 연구에서는 여전히 자본주의 민주주의 국가의 기본 논리를 이루고 있는 베버주의적 계획합리성을 기초로 정부 간 갈등을 검토했다. 기존의 정부 간 갈등 연구는 정부 조직의 관계에만 초점을 둔 탓에 제도적 규약이나 개인적 리더십 차원에서 문제를 이해했다. 그러나 선출직 단체장이 있는 정부 간 갈등은 단순히 정부조직의 문제가 아니다. 본 연구의 주장은 정부 간 갈등이 국가 합리성의 공간적 분화로 인해 발생한다는 것이다. 이를 위해서 본 연구에서는 베버의 국가론과 계획합리성 개념을 - 국가공간론과 스케일 개념을 사용하여 - 공간적인 차원에서 수정했다. 그리고 실체적 합리성의 공간적 분화를 분석의 핵심적인 개념으로 삼아 지방자치제의 의미를 역사적으로 분석했다. 그 결과는 다음과 같다. 1) 한국의 발전국가는 국가스케일을 중심으로 “조국근대화”라는 강력한 실체적 합리성을 가지고 있었다. 2) 그러나, 민주화와 산업화의 토대 위에 시행된 지방자치제는 공간적으로 분화된 실체적 합리성을 형성시켰다. 3) 결국 정부 간 갈등은 국가 하위에 새로 형성된 실체적 합리성 간 갈등이라 할 수 있다.

SV40 T antigen was expressed by the versatile expression vector pEF321 and the regulation of SV40 early promoter by T antigen was investigated. By co-transfecting the T antigen expressing plasmid with each of recombinant plasmid which contains the wild type or mutated SV40 early promoter and bacterial CAT gene into CV1 cells, the changes of early promoter activity by T antigen were estimated. The following results were obtained. i) The pEF321 vector expressed the wild type and cytoplasmic mutant T antigen efficiently in CV1 cells. ii) The wild type early promoter was autoregulated by T antigen showing decreased expression of CAT protein. iii) The mutated early promoter which is defective in replication origin was also autoregulated by T antigen. iv) Transactivation rather then autoregulation has occured by T antigen on the mutated early promoter which is defective in T antigen binding sites Ⅰ, Ⅱ and replication origin indicating that T antigen transactivates not only late promoter but also early promoter of SV40.

외환위기 이후 우리나라 금융기관은 상대적으로 위험성이 높은 기업대출보다, 높은 수익성을 가지는 가계 대출에 관심을 기울이게 되었다. 가계대출이 증가함에 따라 개인신용평가의 중요성이 부각되고, 이에 많은 신용평가시스템이 개발되어 왔다. 하지만 기존의 신용평가시스템은 대출 신청 당시의 데이터 및 과거의 데이터를 가지고 개인의 신용을 평가하기 때문에, 미래 상황에 대한 예측은 고려하지 못한다. 시스템 다이나믹스는 시간의 흐름에 따른 각 요인의 변화를 살펴봄으로써 미래 상황에 대한 예측이 가능한 분석 방법이다. 이에 본 연구에서는 시스템 다이나믹스 방법론을 활용하여 개인 신용 상태에 대한 미래의 동태적인 변화를 예측하여, 그 결과를 반영한 신용평가모델을 개발하고자 한다. 이를 위하여, 먼저 신용평점 영향을 주는 변수들을 선정하고, 이 변수들 간의 인과관계를 밝혀낸 후, 인과관계를 토대로 분석 모델을 구축한 뒤, 컴퓨터 시뮬레이션을 실행함으로써, 대출 희망자의 미래의 신용상태 변화 모양을 예측해 본다. 이러한 시뮬레이션 결과를 신용평가에 반영하게 되면, 금융기관의 신용 대출의 위험을 줄이는 데 기여할 것으로 기대된다.

The purpose of this study was to analyze steel corrosion resistance of concrete containing copper slag. The specimens were made with normal portland cement and pozzolan materials with various replacement ratio and with W/B ratio ranging from 35% to 55%. Compressive strength, coefficient of chloride diffusion, corrosion area ratio and weight reduction ratio were determinated for the test. The results show that the concrete with pozzolan materials is superior resistant to chloride ions compared to the concrete without pozzolan materials. It was observed that blast furnace slag replacement ratio of 20% gives the best results with respect to chloride ion penetration and corrosion tests and observed that copper slag replacement ratio of 10% gives the seperior resistance compared to normal concrete.

[논문]새천년학습자의 ICT 활용에 대한 질적 탐구

김동완,허희옥 교육혁신학술위원회 2011 교육혁신연구 Vol.21 No.1

이 연구는 한국의 새천년학습자의 ICT 활용 특성을 분석하고, 이들을 위한 ICT 교육, 정보교육의 미래지향적 방향을 제안하는 데에 그 목적이 있다. 이를 위하여 본 연구에서는 1980년 말에 태어나 현재 대학생활을 하고 있는 두 사람의 삶의 경험을 이야기 방식으로 수집하고 엮어가면서 경험적 속성을 파악해가는 내러티브 탐구 방법을 이용하였는데, 심층 면담 및 관찰 방법을 이용하여 자료를 수집하고 분석하였다. 그 결과, 기존의 연구 결과와 유사하게, 다양한 테크놀로지의 멀티 활용, 인터넷 자료 의존, 확실한 의사표현, 학생들의 경험과는 동떨어진 ICT 교육 현황 등이 확인되었다. 이를 토대로, 새천년학습자를 위한 미래 ICT 교육의 방향을 제시하였다. This study aims to analyse the ICT use of New Millennium Learners (NMLs) and provide future directions for ICT education. The study conducted a narrative inquiry with two participants in order to investigate the empirical characteristics of NMLs, who being born in the late 1980s, have lived with and learned a great deal from technology. The subjects of this research were two students, one male and one female, both born in 1989. They were university students studying computer education. In-depth interviews, observations and personal journals were employed for data collection. The in-depth interviews consisted of unstructured questions about individuals’ life styles and behaviors on ICT use. There were three 30-60 minute interviews for each subject. In addition to these interviews, each subject’s school life was observed by using participatory observation. Also, each subject’s friends were asked to collect a variety of data regarding the subject’s actions. All data was recording during interviews and then transcribed. Member checking method was applied in order to validate the interpretations and findings. As a result, their several characteristics were interpreted and discussed as follows: First, technology is a significant part of their life. Both subjects began using computer technology even before entering to elementary schools. This allowed both subjects to become comfortable with computers and able to use computers naturally. Second, connectivity in anytime and in anyplace is an essential way to meet people. The communication tool preferred by them was messaging services. The main modes of communication used for both subjects were text messages via mobile phones and computers. Also, both subjects always logged onto messenger programs whenever they were using computers. Even though they were not constantly interacting with someone through the messaging system, being logged onto such programs allowed them to be available and then to communicate with others whenever they wanted. Third, the Internet plays an important role for them to get access information. One participant mostly used the Internet to read news, while the other participant took part mostly in web surfing. Fourth, the use of modern technologies comes naturally for them to learn new things. Both subjects used a variety of portable devices in order to obtain information or listen to internet lectures. Not only were these devices used for studying, but a significant amount of time was spent on entertainment purposes. Lastly, they have their own opinions and preferences, which make their directions to behave. When they encounter a moment or a problem that directly links to their interests, they tried to do their best to complete although it has certain difficulties. However, they seemed like to have a negative perspective or feel aversion against to the situation that they do not like.

Fabrication of Fast-response Ultraviolet Light Sensors with LZO Thin Films using Sol-gel Spin-coating Method

김동완,임재영 한국물리학회 2018 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.72 No.3

The Li-doped ZnO (LZO) thin films with various Li concentrations (0, 1, 3, 5, 7, and 9 at.%)were deposited on quartz substrates by sol-gel spin-coating method. The effects of Li doping onthe structural and optical properties of the thin films were investigated. Undoped ZnO thin filmand LZO thin films had three different diffraction peaks at 31.5 , 34.2 , and 36.0 corresponding tothe ZnO (100), (002), and (101) planes, respectively. The c-axis orientation of the LZO thin filmsincreased with increasing Li doping concentration, owing to the high diffusivity of the Li dopant. Abroad red emission was observed by photoluminescence of the undoped ZnO thin film, whereas LZOthin films had broad green emissions. The transmittance and optical band gap blue-shifted withincreasing Li doping concentration. In terms of photoresponse, all LZO thin films had greater riseand decay rates than the undoped ZnO thin film and the photosensitivity increased with increasingLi doping concentration.
