In this study, it was tried to verify the stability coefficient of newly developed wave dissipating block named Chi-block in the field test. Usually the stability coefficient is determined through the hydraulic experiment and the block is used in the field without in-situ verification. The test breakwater was constructed in Marado and the 5 ton blocks were installed in front of the breakwater with the slope 1:1.5. In order to measure the movement of block the 3-dimensional acceleration sensor was installed in the block and the pressure type wave recorder was installed near the breakwater to measure the wave height which caused to displace the block. The number of blocks to be used for the experiment is 73 and 30 acceleration sensors were installed among them. This experiment starts from the beginning of May, 2017 and was finished in Sep.15 by the typhoon Talim hit Marado, caused displacement of most blocks located near the water surface. It was found that the losses of the Chi-block occurred in the significant wave height of 3.70m ~ 4.09m, which was lower than 4.5m expected from the laboratory tests. This is because the wave direction in the filed was different from that of hydraulic experiment which is normal to the breakwater. The wave hit the breakwater obliquely. This field experiment showed the acceleration sensor monitoring system installed in the wave dissipating block would be useful to check the stability coefficient and the performance of the blocks.

How Does Citizen Participation Influence Local Community Outcomes?: Exploring Impacts of Various Participation Mechanisms on Multiple Community Outcomes in Terms of Competing Values

Oh, Youngmin(吳英敏) 한국지방정부학회 2019 지방정부연구 Vol.23 No.2

학자들과 정책담당자들은 시민참여에 대하여 많은 관심을 가져왔지만 시민참여가 지역의 성과에 미치는 영향을 체계적으로 조사한 연구는 드문 편이다. 이러한 한계를 극복하기 위하여 본 연구는 직접민주주의 참여제도부터 단순 정보제공 참여채널까지 다양한 시민참여 방식을 개념화 한다. 이러한 개념화를 통해 참여채널 간의 상호관계를 분석하고, 여러 참여채널이 지역의 다양한 성과에 미치는 영향을 통계적으로 분석한다. 통계분석과 결과 직접 민주주의 참여제도를 가지고 있는 지방정부일수록 다양한 시민참여 프로그램을 운영하고 있는 것으로 확인되었다. 또한, 다양한 시민참여 프로그램을 운영하는 지방자치단체는 지역의 성과를 효율적으로 달성하지는 않지만 지역성과의 효과성과 형평성을 높이는 것으로 나타났다. Either scholars or practitioners have paid much attention to citizen participation in policy decision-making due to participatory benefits. Despite these benefits, prior studies have not examined the substantial effects of citizen participation mechanisms on local community outcomes. This study conceptualizes a variety of participation mechanisms from direct democracy provisions to informational participatory tools. It investigates that these mechanisms are mutually related to each other by producing multiple community outcomes. The results show that direct democracy provisions are connected to administrative participation mechanisms that produce effective and equitable community outcomes.

원전 조직 및 인적 특성요인 분석을 위한 동태적 시뮬레이션 연구

오영민(Youngmin Oh),김병석(Byung Suk Kim) 대한인간공학회 2013 대한인간공학회 학술대회논문집 Vol.2013 No.10

The recent domestic and overseas nuclear power plant-related incidents and accidents are directly or indirectly associated with safety culture, and thus effective plans for the improvement of safety culture are being called for. While the safety of a nuclear power plant is highly dependent upon technology and equipment, the utilization, maintenance and inspection of the technology and equipment are conducted by employees of the nuclear power plant. Therefore, it is a very critical task to analyze the effects of human activities within a nuclear power plant on the safety of the nuclear power plant, and work out countermeasures; and human behaviors analysis and simulation hold important positions among others. Hence, this study will consider the effects of individual, team, and organizational characteristics factors and behaviors on the safety culture of a nuclear power plant; and, as for its methodology of simulation analysis, it will present the system dynamics approach and cases of its application. On the basis thereof, it will grope for the direction of future simulation research methodology.

Nowadays, social interest toward nuclear safety culture is currently getting higher after the Fukusima nuclear accident in Japan and a series of nuclear accidents domestically such as Gori NPP Unit 1 SBO accident. In other words, it means that our society requires a transformation of paradigm regarding the nuclear safety culture enhancement and an active interdisciplinary combination among various studies such as cultural science and social science. Especially, Learning Organization Theory (LOT) can contribute a lot to the studies of nuclear safety culture establishment method as in the following aspects: Society needs constant exertion in itself; it also needs communication with external forces with continuous changes. We are now searching for the theoretical methods that can enhance the nuclear safety culture and can continuously change in a perspective of Learning Organization Theory. Thus, we want to examine the limitation and problems of the existing nuclear power plants administration. At the same time, we would also like to arrange the current discussions about the Learning Organization Theory and draw the method to apply the theory to the domestic nuclear safety culture.

지방선거에서의 정당공천이 지방정부의 번문욕례 및 관리자의 직무태도에 미치는 영향분석: 미국 지방도시의 정당공천으로부터의 시사점

오영민 ( Youngmin Oh ) 한국행정학회 2016 韓國行政學報 Vol.50 No.1

지방의회 선거가 부활 된 후 지방선거에서의 정당공천에 대하여 많은 찬반논쟁이 있어왔다. 이러한 찬반논쟁에도 불구하고 지방선거에서의 정당공천의 효과를 자료에 대한 심층 통계분석을 통하여 실증적으로 분석한 논문은 드물었다. 본 논문은 이러한 정당연구의 효과에 대한 실증 연구의 부족을 보완하기 위해 정당공천의 효과를 통계적으로 분석한다. 실증분석은 지방선거에서의 정당공천이 지방관료제의 번문욕례(Red Tape)와 관리자의 직무태도(직무만족, 조직몰입)에 미치는 영향을 통계적으로 검증한다. 분석결과 지방선거에서 정당공천을 하는 지방자치단체의 번문욕례의 수준이 정당공천을 실시하지 않는 자치단체보다 높게 나타났다. 또한 정당공천은 지방정부 관리자들의 직무만족 및 조직몰입과 직접적인 관계는 없지만 번문욕례를 증가시킴으로써 지방정부 관리자들의 직무태도에 부정적인 영향을 끼치는 것으로 분석되었다. There have been many controversies over local partisan election since local electionsresumed. Despite such controversies, there have been few quantitative studies analyzing the effects of local partisan election. To fill this gap, this study makes a statistical analysis of how local partisan election affects local public managers` job attitudes and perception of red tape. The analysis shows that local partisan election increases managers` perception of red tape. Local partisan election also has negative impacts on manager`s job satisfaction and organizational commitment because of red tape.

중앙부처 성과평가담당자의 평가부담이 정부성과평가제도의 효과성에 미치는 영향에 대한 탐색적 연구

오영민(Youngmin Oh) 한국국정관리학회 2020 현대사회와 행정 Vol.30 No.3

신공공관리론이 우리나라 정부의 공공관리원칙으로 소개된 후 다양한 형태의 성과관리 및 성과평가제도가 도입되어 운영되어 왔다. 문제는 다양한 평가제도가 운영됨에도 불구하고 국민이 체감하는 공공부문의 성과는 높지 않다는 점이다. 성과가 낮은 것은 다양한 성과관리 및 평가제도를 운영해왔지만 동시에 평가에 관한 부담이 증가해 제도가 형식적으로 운영되고 있기 때문이다. 이런 의미에서 본 연구는 평가부담을 개념화하고 평가부담이 평가효과성에 미치는 인과관계를 구조방정식 모형을 통해 실증적으로 분석하였다. 분석결과 평가제도의 중복과 평가자원의 부족은 평가부담을 높이는 것으로 나타났다. 또한, 평가부담은 평가역량과 평가의 효과성을 낮추는 것으로 분석되었다. 분석결과를 토대로 본 연구는 우리나라 성과평가제도의 평가부담을 완화하고 평가의 효과성을 높이기 위한 시사점을 제시하였다. Since the New Public Management was introduced in Korea, an amount of performance management and evaluation practices have been adopted. Despite numerous performance practices, the public does not feel that government performance has been enhanced a lot. Such poor government performance may be the side effects of high level of evaluation burden from a number of evaluation systems which are prevalent in public organizations in Korea. In this sense, this study analyzes what factors affect evaluation burden and how evaluation burden impacts the effectiveness of performance evaluation systems. The result shows that evaluation duplication and the lack of resources have negative impacts on evaluation burden, which worsens the capacity and effectiveness of evaluation systems. Based on the results, this study suggests policy implications on how burdensome evaluation systems can be streamlined.

우리나라 성과주의 예산제도의 재정성과정보 활용에 대한 실증연구 -재정성과목표관리제도 성과정보 활용의 효과성 분석을 중심으로-

오영민 ( Youngmin Oh ) 한국정책학회 2016 韓國政策學會報 Vol.25 No.1

참여정부시절 도입되었던 우리나라 재정성과목표관리제도가 시행된 지 10년이 경과하였다. 재정성과목표관리제도 하에서 정부 각 부처는 재정사업의 성과목표와 지표를 설정한 성과계획서를 작성하고 달성된 성과와 문제점에 대한 개선방안을 성과보고서를 통해 국회에 보고해야 한다. 재정성과목표관리제도는 재정사업의 성과를 체계적으로 관리함으로써 정부 조직과 공무원들의 성과마인드 향상과 결과 지향적 행정에 기여하였다는 평가를 받고 있다. 이런 긍정적인 평가에도 불구하고 재정성과목표관리제도에서 생산되는 성과정보가 예산심사나 실제 사업의 개선을 위한 유용한 정보로 활용되지 못하고 있다는 비판이 있다. 본 연구는 성과보고서에서 생산된 재정성과정보가 예산 및 사업개선을 위해 사용되고 있는지를 실증적으로 분석한다. 분석결과는 재정성과목표관리제도에서 생성되는 성과정보가 정부와 국회의 예산심사과정과 부처의 사업의 성과개선을 위해서 거의 활용되고 있지 않다는 것을 보여준다. Ten years have passed since the fiscal performance goal system was adopted in Korea Under the system, government agencies should create the annual performance plan including performance indicators and targets. They also submit the performance of financial programs to the National Assembly through the annual performance report. The fiscal performance goal system has contributed to establishing result-oriented management by effectively managing financial program performance. Despite such positive effects, there has been the criticisms that the fiscal performance information produced by the system is not used actively. This study conducts an empirical study analyzing whether the fiscal performance information is used to allocate the budget and to improve the effectiveness of financial programs. The results show that the performance information is little used for budget allocation and program improvement.

Although lymphoepithelial cysts (LECs) of the pancreas are benign lesions, most of them have been treated with surgical resection due to diagnostic difficulty. We report a 66-year-old woman diagnosed with pancreatic LECs. Abdominal ultrasound revealed two masses in the pancreas, which were not visible on the abdominal computed tomography. In an abdominal magnetic resonance imaging, pancreas lesions showed solid tumors, which revealed a low signal intensity on T1-, moderate high signal intensity on T2 weighted images, and homogeneous delayed enhancement in the portal venous phase. Endosonography (EUS) revealed two hypoechoic round masses measuring 1.5 cm and 4.5 cm in the body and tail of the pancreas, respectively. EUS-guided fine needle aspiration (FNA) revealed squamous cells, amorphous keratinous debris, and lymphocytes. The patient was diagnosed with LECs of the pancreas. For the duration of the follow-up period of two years, imaging studies were unchanged. EUS-FNA is useful in making a definite diagnosis and avoiding unnecessary surgery. This is the first case of pancreatic LECs diagnosed with EUS-FNA in Korea. (Korean J Gastroenterol 2017;69:253-258)
