정주용 ( Ju Yong Jeong ),이경희 ( Kyong Hee Lee ) 한국물환경학회 2008 한국물환경학회지 Vol.24 No.2

To analyze the riverine microbial community structure, genetic fingerprints and ecological indexes such as species abundances, diversity, evenness, dominance of targeted rivers in Gyeonggi Province were acquired and evaluated using terminal restriction fragment length polymorphism (T-RFLP) technique. Genetic fingerprinting technique such as T-RFLP, which is able to show the microbial community clearly unlike traditional culture-dependent techniques, was thought to be useful to analyse the riverine microbial ecosystem under various factors. Riverine ecosystem evaluation using visible organisms would give biased results with time, targeted organism and researcher. But, T-RFLP, which can exclude the subjected biases such as culture condition and identification, would be an option to understand natural ecosystem by including the microorganisms that defy culture but perform important functions.

일반논문 : 행정개혁의 집행과정 연구: 정부 3.0의 집행 수용성을 중심으로

정주용 ( Ju Yong Jeong ),하민철 ( Min Cheol Ha ) 고려대학교 정부학연구소 2014 정부학연구 Vol.20 No.3

그동안 행정개혁에 관한 연구는 개혁의 실질적인 집행단위인 지방자치단체와 공무원들 의 수용성에 관심을 기울이지 않았다. 그러면서도 행정개혁의 실패원인을 관료저항으로 매도하고 있는 실정이다. 이 연구는 이러한 ‘관료 낙인론’이 과연 유효한지를 살펴보기 위해 박근혜 정부가 추진하고 있는 행정개혁인 정부 3.0의 집행과정을 분석하였다. 분석 결과, 첫째, 지방자치단체의 최고의사결정자와 관련된 요인들로 1 의사결정점(decision point)의 변경, 2 최고의사결정자의 관심과 지지, 그리고 성향, 3 정책 우선순위 경쟁 등이 정부 3.0의 집행을 어렵게 만드는 것으로 나타났다. 둘째, 일선행정기관의 집행구 조 관련 요인으로는 1 정책집행 실무진의 잦은 교체로 인한 맥락적 지식의 상실, 2 일선관료들의 냉소주의로 인한 ‘나 홀로’ 개혁, 3 지방자치단체 내부의 커뮤니케이션 단절현상이 정부 3.0 집행에 부정적인 영향을 미치는 것을 확인하였다. 셋째, 중앙정부 와의 관계 요인으로는 1 행정개혁의 정책모호성으로 인한 서로 다른 해석체계의 존재, 2 효과적 집행에 필요한 재정지원 부족과 인센티브 부재가 정부 3.0 집행에 걸림돌로 작용하고 있는 것으로 나타났다. 이러한 연구결과로 볼 때, 행정개혁 실패의 원인을 단 순하게 ‘관료저항’으로 설명하는 것은 타당성을 갖추지 못했음을 알 수 있다. 연구결과 에서 도출된 집행과정 상의 여러 가지 문제점들을 극복하기 위한 효과적인 대안들을 모 색하는 것이 필요하다. Cumulative studies on government reform have not paid attention to local governments as a substantial unit for reform and the reform acceptance of local government employees. Despite the deficiency in relevant research, these studies consider the chief reason of government reform failures as bureaucratic resistance. This study identifies such consideration as bureaucratic stigma and analyzes local-level implementation of Government 3.0 as the Park Geun-Hye Administration’s public sector reform in order to examine the legitimacy of the bureaucratic stigmatization argument. The analysis suggests three main findings. First, the reasons related to local-level top decision makers include the change in decision points, poor supports by top decision-makers, and the competition among policy priorities. Second, local agencies often fails to implement reform actions due to the loss of contextual knowledge by frequent change of street-level policy implementers, their non-commitment to reform, and poor communication within local governments. Last, the national government also plays a role as a barrier to national reform, given policy ambiguity embedded in Government 3.0 and insufficient incentives. These findings strongly suggest that bureaucratic resistance cannot entirely explain the reason of reform failure. Thus, successful government reform needs to overcome various problems in policy implementation processes.

The selective catalytic reduction (SCR) technology is well established and used worldwide to control the emissions of NOx from stationary sources: it can be broadly described as passing a hot exhaust gas over a catalyst in the presence of nitrogenous reductants, such as ammonia or urea. The SCR is also currently employed to reduce NOx contained in the exhaust gases of internal combustion engines operated with excess air, such as Diesel engines. One problem of SCR systems for vehicles is the poor activity at low temperatures where most of the NOx are produced during, e.g. cold start-up and on short travelling distances. A method to increase the efficiency of NOx removal by SCR when the exhaust gas temperature is low is to increase the temperature of the exhaust gas and/or of the SCR catalyst. However, principle solutions of the SCR catalytic activity at low temperature are modification of catalysts which can improve the performance of DeNOx at low temperature and catalytic durability, stability and coat ability. In the present study, we developed and analyzed state-of-the-art catalysts working at low temperature.

The optical properties and electrochromism of amorphous $WO_3$ thin films were studied. $WO_3$ thin films with thickness of 3000$\AA$~6000$\AA$ were deposited by vacuum evaporat.ion. All these films were transparent and found to be amorphous in structure by X-ray diffraction analysis and the visible wave length refractive indices were found to be between 1.9 and 2.1 and the optical energey gap to be 3.25 eV. Electrochromic devices were made consisting of IT0 transparent electrode, $WO_3$ thin films, $LiCIO_4$- propylene carbonate and Pt counter electrode. In terms of their operation, the amorphous $WO_3$ films were colored blue by a double injection of electrons from the transparent electrode and lithium ions from the $LiCIO_4$-propylene carbonate organic electrolyte and made colorless by electrochemical oxidation reaction. The electrochromic properties of $WO_3$ thin films including coloration and bleaching, optical density and response time were all found to be strongly dependent on the film deposition condition, electrolyte concentration, sheet resistance of the transparent electrode and applied voltage. 3000$\AA$~6000$\AA$의 두께로 진공 증착한 $WO_3$ 박막의 광특성 및 일렉트로크로미즘에 대하여 연구하였다. 증착된 $WO_3$ 박막은 모두 무색 투명 하였으며 X-선회절 분석결과 비정질 상태로 밝혀졌으며, 비정질 $WO_3$ 박막의 굴절율은 가시광선 영격에서 1.9-2.1로, 광에너지 gap은 3.25eV로 나타났다. ITO투명전극/$WO_3$박막/$LiCIO_4$ ~propylene carbonate/백금 대향전극 구조를 갖는 일렉트로크로믹소자를 구성하여 일렉트로크로믹 특성을 조사하였다. $WO_3$ 박막의 coloration/과 bleaching현상은 $LiCIO_{4}$~propylene carbonate유기전해질과 ITO투명전극으로 부터 $Li^{+}$이온과 전자의 이중주입에 의하여 청색으로 나타났으며, 가역적으로 전기 화학적인 산화반응에 의하여 bleaching현상이 일어났다. Coloration과 bleaching현상, 광학밀도, 구동전압 및 응답속도 등의 일렉트로크로믹 특성은 $WO_3$ 박막의 증착조건, 전해액 농도, 투명전극의 sheet resistance 인가전압에 크게 의존하는 것으로 밝혀졌다.

This study was conducted to propose measures of water quality management as the water criteria for waterscape facilities which have been highlighted as alternatives to wading pools in summer season was legislated. The number of public waterscape facilities has reached 290 sites in Gyeounggi province and 971 sites in South Korea in 2017. The water tank capacity of 80.3 % public waterscape facilities was less than $100m^3$. Facilities with disinfection system were only 6.5 % and facilities with filtration function were also very low at 6.9 %. Most of the waterscape facilities, about 93%, are expected to be vulnerable to complying with revised water quality criteria because they have to be disinfected by handling. Chlorine disinfectants, which are more persistent than ozone or ultraviolet sterilization methods, are more preferred. However, care should be taken when adding disinfectans because hypochlorous acid, which is an effective component of chlorine disinfectant, remains after the disinfection, but it is easily decomposed with time. For this study, ${\bigcirc}{\bigcirc}$ park floor fountain with a capacity of $63m^3$ was selected and the amount of free residual chlorine concentration was measured by injecting a certain amount of chlorine bleach. As a result, it took 5 hours to decrease from the water quality standard of 4 mg/L to 0.04 mg/L. If the waterscape facility is operated for 7 to 8 hours, the chlorine bleach should be re-injected after 5 hours. In addition, the problem of pH increase due to the input of chlorine disinfectant is expected, and the neutralization method using vinegar was proposed.
