환도(環跳)(GB<sub>30</sub>)·양릉천(陽陵泉)(GB<sub>34</sub>) 온침(溫鍼)이 CFA로 유발된 백서의 류마티스 관절염에 미치는 영향
정주용,조명래,Jeong, Joo Yong,Cho, Myoung Rae 대한침구의학회 2015 대한침구의학회지 Vol.28 No.1
Objectives : The purpose of this study was to investigate the effects of warm needling at $GB_{30}{\cdot}GB_{34}$ on Complete Freund's Adjuvant(CFA)-induced rheumatoid arthritis in rats. Methods : Arthritis was induced by injecting CFA subcutaneously into the left knee joint and paw. Acupuncture(AT) and warm needling(W-AT0.5, W-AT1.0) were injected at $GB_{30}{\cdot}GB_{34}$, every other day for a total of 5 times beginning on day 10 after the CFA injection. Thereafter, external shape, paw edema, serum aminotransferase and anti-inflammatory factors were assessed, and hematological and histological observations were made. Results : In paw edema volume all 3 groups(AT, W-AT0.5, W-AT1.0) showed significant decrease compared to the CFA control group. In TNF-${\alpha}$ and IL-6, all 3 groups showed significant decrease compared to CFA control group. In AST and ALT all 3 groups showed no significant change. In IL-$1{\beta}$, W-AT0.5 and W-AT1.0, groups showed significant decrease compared to the CFA control group. Leucocyte, erythrocyte and thrombocyte, all 3 groups showed no significant change. In histological observations, all 3 groups were similar to the intact group in terms of synoviocyte, cartilage lacuna and cartilage cells. Conclusions : The results suggest that warm needling at $GB_{30}{\cdot}GB_{34}$, has the effect of suppressing inflammation of CFA-induced rheumatoid arthritis in rats.
일반논문 : 행정개혁의 집행과정 연구: 정부 3.0의 집행 수용성을 중심으로

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.
유전자지문분석법(T-RFLP)을 이용한 하천 미생물의 다양성 평가
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.

한국항공우주산업(주)는 ETRI 주관사업인 통신방송위성 Ka/Ku 대역 중계기의 EQM 모델 개발사업에 참여하고 있다. 본 논문에서는 중계기의 지상시험 기간동안에 사용하기 위한 원격검침데이터의 획득과 모니터링 시스템의 설계 내용을 다루고 있으며, 원격검침데이터의 획득 하드웨어, 포맷팅 및 디코딩 관련 기법이 기술되고 있다. 본 시스템은 원격검침데이터의 모니터링 통제 및 시현을 담당하는 버스컨트롤러(Bus Controller, BC)와 원격검침 원시데이터의 획득을 담당하는 리모트 터미널(Remote Terminal, RT)등의 두 파트로 구성된다. 그리고, 두 파트사이의 원격검침 데이터의 전송은 MIL-STD-1553B 인터페이스를 적용하고 있다. 이러한 BC와 RT는 중계기 시험기간 동안에 중계기 내의 장비에 전기적 손상을 방지하도록 통신방송위성 중계기의 기능규격서와 접속규격서를 만족하도록 설계되어진다. KAI has been participated in ETRI program of EQM (Electrical Qualification Model) development in the communication and broadcasting satellite Ku and Ka bands payload system. This paper describes the design overview of the telemetry acquisition and monitoring system for the transponder of Communication & Broadcasting Satellite (CBS) Payload System at the ground test period. Also, the telemetry acquisition hardware, telemetry formatting and decoding techniques are specified in the paper. The system is divided into two parts that are the Bus Controller (BC) Station for monitoring control and display of telemetry data, and the Remote Terminal (RT) Unit for telemetry raw data acquisition. And, the system adapts the MIL-ST1553B interface for telemetry data transfer between BC Station and RT Unit. Both parts are designed appropriately to meet the functional and interface requirements, which is to avoid damaging the EQM equipment during test.

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.
