본 연구는 상류의 개발행위와 더불어 현재 수질관리의 기준이 되는 오염총량관리제를 대상으로 '규모의 경제'의 논리를 따른다는 가정 하에, 지자체간에 협조를 통해 비용을 절감하여 서로 혜택을 볼 수 있도록 상 하류 지자체와 중앙정부 등 관련 당사자들 간의 비용배분 방안을 도출하는 것을 목적으로 하였다. 이를 위해서 광주광역시에 위치한 평동산업단지와 영본B, 영본C를 대상으로 광주, 전남, 중앙정부를 이해당사자로 하여 협조적 상황 하에서 대상 비용배분 문제를 정의하였고, 협조적 게임이론에 근거한 SCRB법 및 샤플리법을 적용하여 비용배분 결과를 제시하였다. 우선 광주와 전남이 각각 삭감해야 할 오염량을 산정하고, 해당 삭감량 만큼 처리하기 위한 하수처리시설의 규모를 설정하였다. 또한 하수처리시설의 건설비와 하수관거 공사비, 유지관리비를 산정하였으며, 하수처리시설의 내용연수인 20년간의 총비용을 2010년 현재가치 기준으로 산정하였다. 상 하류 지자체가 공동으로 대처할 경우 20년간 총비용은 416,311.8 백만원, 개별로 대처할 경우 464,439.6 백만원이며, 공동 대처가 42,359.3 백만원이 절감되므로 양 지자체 모두 협조적 게임에 응할 기본배경은 성립되었다. SCRB법에 의한 지자체별 비용배분율을 산정 결과, 광주 74.24%, 전남 25.76%로 산정되었으며, 2001～2010년 하수도 세입현황을 기준으로 중앙정부의 지원 비율은 10년간 최소 23.98%, 평균 29.22%, 최대 34.17%로, 각각의 비율별로 중앙정부, 광주, 전남의 비용분담액을 도출하였다. 본 논문에서는 개략적으로 비용을 산정하였으나 오염총량관리 사업은 막대한 예산을 필요로 하기 때문에 실제로 두 지자체가 협조하여 비용배분을 하게 된다면 하수처리시설의 수질개선효과, 하수처리시설 위치선정, 사업비용 등을 세밀하게 분석해야 할 것이다. 본 논문은 오염총량관리제에서 제시하는 목표수질을 대상으로 하였으나, 지자체의 정책에 따라 친수활동 증대와 생태 자연환경 개선 등과 같은 수질개선에 따른 간접적인 효과를 고려하여 오염 총량관리제의 목표수질보다 더 나은 수질을 원할 수도 있을 것이다. 협조적 게임의 상황을 복잡하게 하여 해결 가능성이 낮아질 수 있으나, 수질개선에 의한 다양한 효과를 편익으로 산정할 수 있다면 이를 협조적 게임에 적용하여 전반적인 수질개선에 대한 지자체의 적극적 활동을 유도할 수도 있을 것이다.

July 1, 2004 Seoul Metropolitan city is operating the Median Bus Lane System on Gangnam Main Street, Seongsan-Susaek-ro (Road) and Dobong- Mia-ro (Road) as one of the systematic reorganizations in public transportation. It has been assumed that there was an improvement in the speed of bus considering that the Median Bus Lane System practiced on Cheonho-daero (Main Street) since 1996 have had 35km/h on the average. If the Median Bus Lane goes into effect, there is a problem with the left turn on the crossroad. The buses go on the existing first lane so that the left fuming cars cannot help but turn left on the second lane. In case that the Median Bus Lane is put into practice, the left turn on the crossroad should not be allowed. However, if the left turn is not permitted on the crossroads in the aforementioned main streets, neighboring residents will complain about it and there will be some difficulties in finding other detour. On the premise that the prevalent left turn on the crossroads is allowed while the Median Bus Lane is being put into practice, this study suggests the separation of a stop line between buses and other vehicles as a way of fuming left in a safe manner and a way to calculate the appropriate distance.

This study is aim to research trend of private security and to suggest direction of improvement to sector of private security. This study has been to analyzed to be useful social network analysis(particularly Degree Centrality and Clossness Centrality) for using typical research method about trend of academic subject. As a result of Degree Centrality and Clossness Centrality, Individual factors such as Job Stress and Job satisfaction of private security are more keyword than institutional factors and policy factors such as Security Services Industry Act and training for Private Security guards. It means that research trend of private security are to study Individual factors rather than institutional factors and policy factors. But, this study is a limit as follows; First, An object of study is only to searching article in National Assembly Liberary. A follow-up studies are need to expand the range of an object of study for private security.

The value of social network and entrepreneurial orientation has widely been acknowledged as a critical resource of business success. However, the previous studies did not specify each role and conceptually have examined them as separate antecedents of firm performance. This study develops propositions concerning network capabilities and investigates the moderating effects of network structures (degree centrality, closeness centrality, and betweenness centrality) on the relationship between entrepreneurial orientation and firm performance. This research conducted with a sample of 115 small consulting companies in Korea. The findings indicate that closeness centrality moderates the relationship between proactiveness and performance. Also, the combination of betweenness centrality and proactiveness exerts a positive impact on performance. Accordingly, degree centrality enhances the influence of innovativeness on performance. In particular, betweenness centrality exacerbates the influence of risk-taking on performance against our expectation. Overall, these findings conclude the synergistic effects of network capability and entrepreneurial orientation on firm performance. Finally, practical implications and academic propositions are presented regarding the way firms could most effectively utilize entrepreneurial orientation and network capability to maximize firm performance.

Decentralized group key management mechanisms offer beneficial solutions to enhance the scalability and reliability of a secure multicast framework by confining the impact of a membership change in a local area. However, many of the previous decentralized solutions reveal the plaintext to the intermediate relaying proxies, or require the key distribution center to coordinate secure group communications between subgroups. In this study, we propose a decentralized group key management scheme that features a mechanism allowing a service provider to deliver the group key to valid members in a distributed manner using the proxy cryptography. In the proposed scheme, the key distribution center is eliminated while data confidentiality of the transmitted message is provided during the message delivery process. The proposed scheme can support a secure group communication in dynamic network environments where there is no trusted central controller for the whole network and the network topology changes frequently.

Purpose: We investigated the association between defoliant exposure and survival to discharge after out-of-hospital cardiac arrest. Methods: This is a retrospective case-control study based on the cardiopulmonary resuscitation (CPR) registry. The electronic medical records of out-of-hospital cardiac arrest victims from 6/9/2008 to 12/31/2016 were analyzed statistically. The case patients group had a history of defoliant exposure while the control group did not. Among the 401 victims studied, a total of 110 patients were male out-of-hospital cardiac arrest patients. Baseline characteristics and the parameters involved in cardiac arrest were analyzed and compared between the two groups after propensity score matching. The primary outcome was survival to discharge, and secondary outcomes were sustained return of spontaneous circulation (ROSC) and survival to admission. Results: After propensity score matching a total of 50 patients (case=25, control=25) were analyzed. Primary outcome (survival to discharge) was not significantly different between case and control groups [(OR, 1.759; 95% C.I., 0.491-6.309) and (OR, 1.842; 95% C.I., 0.515-6.593), respectively]. In the subgroup analysis, there were also no significant differences between the control group and subgroups in primary and secondary outcomes according to defoliant exposure severity. Conclusion: There is no statistically significant association between defoliant exposure and survival of out-of-hospital cardiac arrest.

Background: Using KIDS-KAERS database (KIDS-KD) from 2016 to 2020, the aim is to investigate signals of adverse events of alpha-adrenoceptor antagonists and to present adverse events that are not included in the precautions for use when marketing approval. Methods: This study was conducted by disproportionality analysis. Data mining analysis was performed to detect signals of alpha-adrenoceptor antagonists, such as terazosin, doxazosin, alfuzosin, silodosin, and tamsulosin. The signal was defined by three criteria as proportional reporting ratio (PRR), reporting odds ratio (ROR), and information component (IC). Detected signals were compared with product labeling and the European Medicines Agency-Important Medical Events list. Results: Out of the total number of 408,077 reports for adverse events, 6,750 cases were reported as adverse events of alpha-adrenoceptor antagonists. Dizziness, mouth dryness, hypotension postural, and oedema peripheral are identified as common adverse events of five alpha-adrenoceptor antagonists and are typically listed on drug labels. However, new signals were detected for pneumonia, chronic obstructive airway disease, eye diseases such as glaucoma and cataracts, fracture, and ileus of tamsulosin that were not previously listed on the drug labels in Korea. Conclusions: This study identified signals related to adverse drug reactions of alpha-adrenoceptor antagonists and presented serious adverse events, suggesting new adverse reactions to be aware of when using alpha-adrenoceptor antagonists.
