촛불집회와 태극기집회 사이에서 - 기독교인의 반정부적 정치참여에 대한 고찰

정원호(Jung, Wonho) 한국기독교사회윤리학회 2020 기독교사회윤리 Vol.47 No.-

로마서 13장 1-7절의 본문과 정교분리의 원칙은 정치에 대한 기독교인의 무관심이나 수동적 태도를 규범화하거나 정당화할 근거로 사용될 수 없다. 그것은 또한 특정한 종교적 교리를 떠나 모든 사람들에게 적용될 수 있는 도덕과 정의의 규범에 관련된 정치적 문제에 교회가 종교적 민감성과 권위를 가지고 개입하는 것을 금지하지 않는다. 이러한 주장을 뒷받침하기 위해 본 글은 로마서 13장 1-7절의 본문에 관련된 해석들을 살펴보고 그 구절을 오늘날의 정치 현실에 어떻게 적용하는 것이 가장 본문과 상황에 충실한 해석인지를 논할 것이다. 나아가 정교분리 원칙에 관한 미국 연방대법원의 몇 가지 중요한 판례들을 살펴봄으로써 기독교적 정치참여가 정교분리의 원칙과 조화를 이루고 정당성을 갖기 위해서는 엄밀한 의미의 정치적인 문제나 순수하게 종교적인 문제가 아닌 보편적 도덕과 정의의 문제에 근거한 것이어야 한다는 사실을 보여 줄 것이다. The biblical passage from Romans 13:1-7 and the principle of the Separation of Church and State cannot be legitimately invoked to justify Christian political indifference and passivity or to make them normative. Nor do the passage and the principle prohibit Christian political engagement with religious sensibilities and authority in the matters of moral and justice issues that are not specifically religious in nature but applicable to everyone. To support this argument the Romans passage is discussed for its interpretation that does justice to the biblical text and fits best for our political context. And then several important U.S. Supreme Court cases involving the Separation of Church and State are discussed to show that Christian political involvement should not be prompted by matters that are strictly political or purely religious but it should be made for the matters of universal moral values like justice.

It is important to recognize the drowning person as soon as possible in maritime accidents. In real maritime accidents, it is difficult to identify the drowning person because of their small size compared to the marine environment. To solve this problem, this paper presents a methodology to detect small target using commercial games with 3D graphical engines. Proposed methodology combines as following four steps: (1) divide high-resolution original image into several small patches, (2) image processing using CLAHE and Canny edge detection, (3) detecting small targets using convolutional neural networks (4) restore patches into original image. To detect small target in the high-resolution original image, small patches and image processing techniques are considered to raise the signal-to-noise ratio of the small target. The small patches are uses as test data of convolutional neural networks (CNN), the softmax values of each patch are displayed on the reconstructed image. To enhance the accuracy of CNN, virtual image data acquired from the commercial game using the 3D graphical engine are used as training data. In order to verify the performance of the proposed methodology, a case study of real maritime accident situation was conducted. The performance of the proposed methodology outperforms original deep convolutional neural networks.

딥러닝 알고리즘 훈련을 위해서 충분한 양의 데이터 확보가 필수적이다. 그러나, 공학시스템에서 데이터 취득은 매우 어렵거나, 상황에 따라 불가능한 경우가 존재한다. 이러한 데이터 부족 문제는 딥러닝 알고리즘 개발에 큰 걸림돌이 되고 있다. 본 논문은 구조물 건전성 진단을 위한 딥러닝 알고리즘 개발에서 발생하는 데이터 부족 문제 해결을 시도하였다. 깊은 생성 모델을 구축하고 딥러닝 학습을 위한 훈련 데이터를 생성하는 방법을 제안한다. 제안된 방법의 성능을 검증하기 위해 수상 양식장 어망 데이터를 바탕으로 사례 연구를 진행하였다. 본 연구는 제안된 심층 생성 모델을 통해 데이터를 직접 만들어 냄으로써 구조물 건전성 진단에서 발생되는 데이터 부족 문제 해결에 기여할 것으로 기대된다. A sufficient amount of data are required for training deep learning algorithms. However, in engineered systems, data acquisition is difficult or sometimes not feasible. A dearth of data is one of the major challenges for the development of deep learning algorithms. This paper proposes a deep generative model to generate pseudo data that emulate real data. To verify the performance of the proposed model, a case study is conducted using aquaculture fishnet image data. We demonstrate that the insufficient data problem in structural health monitoring can be relieved by generating data through the proposed deep generative model. The reliability of engineered systems can be improved by incorporating the deep learning algorithms developed with real data as well as generated data.

농작물재해보험의 위험분산체계 개선방안

정원호 ( Wonho Chung ) 한국축산경영학회 2013 농업경영정책연구 Vol.40 No.2

2012년 대형 재해로 인하여 민영보험사는 물론 국가재보험과 해외재보험의 손실폭이 확대됨에 따라 농작물재해보험의 위험분산체계에 대한 재검토가 절실한 시점이다. 민영 보험사들은 해외재보험사들의 재보험요율 인상압력으로 2013년 사업추진이 불투명해지자 정부에게 국가재보험의 인수범위 확대를 통한 지원을 요청하였다. 본 연구에서 살펴본 바와 같이 단순히 국가재보험의 인수범위만 확대하는 것은 민영보험사에서 정부로의 손실의 전가에 불과하므로 보다 근본적인 위험분산체계의 개선방안이 필요하다. 주요 선진국의 국가재보험 사례의 검토와 함께 경험분포와 확률분포에 기초한 재보험 요율을 추정한 결과 일부 손해율 구간에 대해 추가적으로 해외재보험에 가입하는 것보다 손해율 전체 구간에 대하여 민영보험서와 국가가 손익을 분담함으로써 국내에서 위험을 분산하는 것이 국가 전체적인 차원에서 유리한 것으로 나타났다. 지속적인 자료의 축적을 통해 추가적인 분석이 필요하겠지만 위험그룹별로 차별화된 국가재보험을 적용 하는 것이 국가재보험의 안정적인 운영에 도움이 될 것으로 판단된다. 즉, 저위험 그룹에 대해서는 모든 손해율 구간에서 민영보험사와 국가재보험이 위험을 분담하며, 고위 험 그룹의 경우는 일정수준(예컨대 손해율 500%) 이내의 위험은 민영보험사와 국가가 분담하고 500%를 초과하는 극단적인 손해에 한해서만 해외재재보험을 활용하는 방안을 고려할 수 있다. 이 경우 해외재재보험사들이 제시하는 보험료의 적절성을 검토하기 위 하여 추가적인 자료의 수집과 해외재보험시장에 대한 정보의 확보가 선결되어야 한다. 아울러 향후 농작물보험의 확대를 대비하여 재보험기금의 안정적인 운영 및 재원확보를 위한 방안도 검토할 필요가 있을 것으로 보인다. This study reviews our current reinsurance system for crop insurance program and finds improvements on the system. We compare our reinsure-ance system with those of several developed countries and analyze returns of private institutes and government under our system to find improve-ments. As a result, we suggest to distribute risks between private insurance companies and government within the country through all levels of loss ratio for each of the two risk groups, high risk and low risk groups.

Background/Aims: Mirocam® capsule endoscopy has been widely used in Korea; however, data with respect to Mirocam® capsule endoscopy is lacking. We have assessed the factors affecting complete small bowel studies and diagnostic yield in Mirocam® capsule endoscopic studies. Methods: We retrospectively analyzed 103 cases that were assessed with Mirocam® capsule endoscopy between June 2007 and February 2010 at Guro Korea University Hospital. Results: The mean age of the 103 cases was 55.47 years (range, 16-99 years) and 67 cases (65%) were male. The indications for capsule endoscopy were hematochezia/melena (77 cases, 74.8%), anemia (8 cases, 7.8%), abdominal pain (12 cases, 11.7%), and miscellaneous (weight loss and chronic diarrhea; 6 cases, 5.8%). The mean stomach transit time was 59.9±88.3 minutes (range, 1-630 minutes) and the mean small bowel transit time was 396.0±131.7 minutes (range, 117-708 minutes). The rate of successfully performing a complete small bowel study was 82.5% (85 cases), and the stomach transit time was a significant factor for a complete small bowel study (OR=0.991, 95% CI= 0.984-0.998, P=0.012). The diagnostic yield was 51.5% (53 cases); visual quality was a significant factor in determining the diagnostic yield (OR=6.776, 95% CI=1.32-34.70, P=0.022). Conclusions: In a Mirocam® capsule endoscopic study, short stomach transit time was a significant factor affecting completion of the small bowel study. Achieving excellent visual quality by good bowel preparation was a significant factor for improving the diagnostic yield. (Intest Res 2011;9:0-34)

Who Becomes a Leader in Teams: The Function of Motivation and Empowerment

Wonho Jeung(정원호) 한국인사조직학회 2018 한국인사ㆍ조직학회 발표논문집 Vol.2018 No.2

This study explores the emergence of leaders in newly-formed teams based on two motivational aspects of individual differences: motivation to lead (MTL) and leadership self-efficacy (LSE). Sampling from the soldiers in the Korean Army Training Center, it was found that MTL and LSE are positively related to leader emergence outcomes. In addition, LSE was found to mediate the relationships between MTL and leader emergence. Moreover, this study introduces the moderating role of external leaders on the relationship between motives and leader emergence in leaderless teams. It was found that the empowering leadership behavior of external leaders moderates the effects of MTL and MTL on leader emergence.

정원호 ( Wonho Jeung ) 한국생산성학회 2019 生産性論集 Vol.33 No.4

This study examined the influential process of perceived organizational support on performance of organizational members. First, this study discussed the effects of perceived organizational support on performance of organizational members based on previous studies and social exchange theory. Second, it introduced thriving at work of organizational members as a mediator on the relationships between perceived organizational support and performance based on conservation of resource theory and the broaden-and build theory. Finally, it introduced resilience of organizational members as a moderator on the effects of thriving at work on performance as well as the indirect effects of perceived organizational support on performance through thriving at work. Data was collected from various organizations, including military and business organizations. The results of this study are as follows. First, perceived organizational support is positively related to performance of organizational members. Members with higher perceived organizational support tend to perform better than those with lower perceived organizational support. Second, the effects of perceived organizational support on performance is positively mediated by thriving at work of organizational members. Members with higher perceived organizational support tend to increase the level of thriving at work of organizational members, and in turn, they tend to perform better than those with lower perceived organizational support. Third, the effects of thriving at work on performance is positively moderated by the level of resilience of organizational members. The effects of thriving at work on performance is stronger for those with higher level of resilience of organizational members than those with lower level of resilience. Finally, the indirect effects of perceived organizational support on performance through thriving at work is also moderated by the level of resilience of organizational members. The results of this study provide several theoretical and practical implications. First, this study expand the extant studies on perceived organizational support by showing potential influential process of perceived organizational support on performance. Second, it also expand the understanding of previous studies on thriving at work by explaining the relationships with perceived organizational support and performance. It also emphasizes the importance of organizational efforts to make their employees positively perceive their supports since it facilitates performance of organizational members. It is also important for organizations to strive to increase the level of thriving at work and resilience of organizational members in order to achieve better performance.

농가경영안정을 위한 농업수입보험제도 도입에 관한 연구

정원호(Wonho Chung),최경환(Kyung-Hwan Choi),임지은(Ji-Eun Lim),김윤종(Yoon-Jong Kim),최세균 한국농촌경제연구원 2013 한국농촌경제연구원 기본연구보고서 Vol.- No.-

Background of Research As the volatility of quantity and prices of agricultural products increases due to irregular weather events and the expansion of market openness, Korean farmers face management uncertainty increasingly. Our current management stabilization policy is not sufficient because it covers either price fall conditionally only for limited items or quantity loss caused by natural disasters. Furthermore, direct payment for income stabilization considered for several years could not be introduced. All of these motivated us to start to consider revenue insurance. There have been various opinions on the possibility and timing of introduction of revenue insurance while most people agree that revenue insurance could contribute to farm income stabilization and increase social welfare. The Korean government is planning to introduce the pilot program of revenue insurance in 2015 based on the result of two years of tabletop exercises. Therefore, at this stage we need to review the conditions, plan, and consideration for introducing revenue insurance to find policy implications. Method of Research This study reviewed the need for the introduction of revenue insurance, conditions and circumstances, desired effects, farmers" need, proper items, examples of foreign countries, plans and challenges. We reviewed previous studies and materials, collected and analyzed the insurance data, conducted farm surveys and econometric analysis, and considered all possible ideas suggested in seminars, meetings, and conferences. Research Results and Implications We found that all conditions for introducing revenue insurance are not fully satisfied but there could be possible ways to introduce it in our circumstances. We also found that revenue insurance will stabilize farm income by reducing the income volatility by 5~40% and increase social benefits by 27.5 billion won. In addition, many of the survey participants are interested in the program. Based on the results, the positive effect will be maximized if we introduce the program smoothly at the possible level. This study provides eight suggestions for introducing revenue insurance. First of all, a reasonable foundation considering our farm and market conditions should be established. Second, the development of an accurate and systematic insurance database is indispensable. Third, farmer"s need should be considered carefully from the stage of system design. Fourth, the revenue insurance needs to be related to current farm management stabilization programs without overlapping or conflicts. Fifth, a loss adjustment measure better than in crop insurance should be prepared for the complicated revenue insurance. Sixth, government subsidy in the reinsurance system is more important than in crop insurance because the contingency of price volatility would not be guaranteed. Seventh, revenue insurance requires more governmental budget so that the items and coverage level should be determined under the budget constraints. Finally, the program should be introduced following a phased road map based on the result of tabletop exercises and pilot programs.
