Economics of Municipal Solid Waste Management Options - A Synthetic Approach
나태준(Lah T. J.) 한국국정관리학회 2002 현대사회와 행정 Vol.12 No.2
Waste management policy should take into account the full-cost accounting whenever possible. However, as the current set of literature shows, comprehensive analysis is very rare and incomplete, since the costs and benefits of the municipal solid waste (MSW) management options are dependent on the specific conditions of a system. To overcome this problem, this article compares the cost-benefit structure of recycling, incineration, and landfilling, and attempts to show a cost-benefit framework of MSW management options. Although the field currently lacks comprehensive and objective cost-benefit model for comparing the MSW options, such a model can be constructed by synthesizing the literature. When all costs and benefits are considered, recycling becomes competitive in the low cost estimation. However, in the high cost estimates, recycling is the worst among the three options. The results suggest that the extensive data collection and validation are needed to reach valid conclusions.
How PUBLIC MANAGEMENT SHAPES PUBLIC PARTICIPATION - A CONCEPTUAL FRAMEWORK
나태준(Lah T.J.) 한국국정관리학회 2002 현대사회와 행정 Vol.12 No.3
This research attempts to present a framework of how public management shapes public participation in the policy process. By looking conceptually at the managerial practices in decision-making process, the paper analyzes how bureaucracy determines the degree of public participation. Various components that influence managerial practices are grouped into five categories: individual variable, organizational structure, structure of participation program, nature of policy, and political dynamics. This study views participation as a result of the negotiation and compromise between the bureaucratic module and democratic norms.
SOFC용 전극 제작 조건에 따른 전극 성능 및 구조 분석
나세윤(Lah, Se-Yun),지영석(Jee, Young-Seok),이윤호(Lee, Yoon-Ho),조구영(Cho, Goo-Young),차석원(Cha, Suk-Won) 한국신재생에너지학회 2009 한국신재생에너지학회 학술대회논문집 Vol.2009 No.06
In order to develop SOFC cell performance, many kind of things were investigated. Electrode microstructure is the one of them therefore we focus on electrodes fabrication easily and efficiently. We can fabricate electrodes easily with Pt using DC magnetron sputtering and sintering. However sputtering is difficult to handle and to grow porous electrodes what we require. On the other hand sintering is much easier than sputtering to make porous and adhesive electrodes. So in this paper we deal with sintering and optimize to deposit electrodes conditions by analyzing electrode microstructure with sacnning electron microscopy(SEM) micrograph. Also, we compare electrochemical performance of cells fabricated by sputtering and sintering.
한국어 학습자의 발표 담화에 나타난 담화 오류 양상- 중국인과 베트남인 학습자를 대상으로
나은선(Lah Eunsun) 한국문화융합학회 2018 문화와 융합 Vol.40 No.4
이 연구는 한국어 학습자의 발표 담화에 나타난 담화 오류의 양상을 살피는데 목적이 있으며 중국인 학부 과정 학습자 4명과 베트남인 학부 과정 학습자 6명의 발표 담화를 전사하고 국립국어원 한국어 학습자 구어 말뭉치의 중국인 학습자 6명과 베트남인 학습자 4명의 발표 담화 전사 자료를 참고하여 중국인 학습자 10명과 베트남인 학습자 10명 총 20명의 발표 담화에 나타난 담화 오류의 양상을 살펴보았다. 발표 담화에 나타난 담화 오류는 세 부분으로 나누어 살펴봤는데 1) 지시 표현 오류 2) 격식성 오류 3) 관용적 표현 오류로 나누었다. 또한 지시 표현 오류는 누락과 오사용 오류로 격식성 오류는 어휘 오류, 비격식적 표현 오류, 종결형 오류로, 관용적 표현 오류는 공손성 오류, 담화 종결표현 오류로 나누어 살펴보았다. 지시 표현 오류에서 누락과 오사용 오류가 나타났으며 격식성 오류에서는 어휘를 격식성에 맞지 않게 쓴 경우와 혼잣말 형식의 적절하지 않은 비격식적 표현을 사용한 경우, 격식체 종결형을 사용하지 않은 종결형 오류 등을 볼 수 있었으며 관용적 표현 오류에서는 선어말어미 ‘-겠-’을 누락하여 사용한 공손성 오류, 관용적인 담화 종결표현을 사용하지 않은 오류 등이 나타났다. 이를 통해 발표 담화에서 특징적인 지시표현, 격식성에 맞는 표현, 관용적 표현 등을 사용하도록 지도하는 것이 필요함을 알 수 있었다. This study aims at examining the discourse error in presentation discourse of Korean language learners. This study examined the error in presentation discourse through transcribing the presentation discourse of ten Chinese and Vietnamese undergraduate students and through referring to transcribing material of presentation discourse of ten Chinese and Vietnamese students from Korean learners’ spoken corpus collected in national institute of Korean language. The discourse error was reviewed classified into three parts, 1) referring expression error, 2) formality error, 3) idiomatic expression error. Referring expression error was classified into omission and misuse, and formality error was classified into vocabulary, informal expression and final- ending error, and idiomatic expression error was classified into politeness error and discourse ending expression error. In referring expression error, commission and misuse of referring expression was observed and in formality error, the unuse of formal vocabulary, the use of informal expression like talking to themselves, the unuse of formal final ending were observed. In idiomatic expression error, politeness error that denotes omission error of pre-final ending ‘-겠-’ and the unuse of idiomaic discourse ending expression were observed. This study shows the necessity of education related to referring expression and formal feature in addition to idiomatiic expression of presentation discourse.
