본 논문에서는 암호화폐거래소 이용자를 보호하고 거래소의 안정적인 운영환경을 확보하기 위한 국내 암호화폐거래소 운영리스크 경감방안을 제시한다. 암호화폐거래소를 이용해 암호화폐시장에 참여하는 시장참여자에게 암호화폐의 가격변동 리스크만큼 위협적인 리스크는 암호화폐거래소 리스크이다. 암호화폐시장에서는 암호화폐의 거래 익명성을 악용한 탈세, 범죄이용, 유사수신 사기, 자금세탁 등 불법거래가 빈번히 발생하고 있고 이외에도 사이버 침해사고와 내부인력에 의한 손실 사고가 끊이지 않고 있으며, 이로 인한 손실이 거래소 이용자에게 고스란히 전가되고 있다. 본 연구에서는 현재 국내 암호화폐거래소의 운영 실태와 이용자 손실 발생 사고에 대한 대응 등을 거래소 운영리스크의 관점에서 분석하여, 이용자를 고객으로 유치하고 고객인 이용자를 보호하기 위한 거래소 플랫폼의 발전 방향을 제시한다.

Endoscopic retrograde cholangiopancreatography (ERCP) plays a crucial role in the management of pancreaticobiliary disorders. Although the ERCP technique has been refined over the past five decades, it remains one of the endoscopic procedures with the highest rate of complications. Risk factors for ERCP-related complications are broadly classified into patient-, procedure-, and operator-related risk factors. Although non-modifiable, patient-related risk factors allow for the closer monitoring and instatement of preventive measures. Post-ERCP pancreatitis is the most common complication of ERCP. Risk reduction strategies include intravenous hydration, rectal nonsteroidal anti-inflammatory drugs, and pancreatic stent placement in selected patients. Perforation is associated with significant morbidity and mortality, and prompt recognition and treatment of ERCP-related perforations are key to ensuring good clinical outcomes. Endoscopy plays an expanding role in the treatment of perforations. Specific management strategies depend on the location of the perforation and the patient's clinical status. The risk of post-ERCP bleeding can be attenuated by preprocedural optimization and adoption of intra-procedural techniques. Endoscopic measures are the mainstay of management for post-ERCP bleeding. Escalation to angioembolization or surgery may be required for refractory bleeding. Post-ERCP cholangitis can be reduced with antibiotic prophylaxis in high risk patients. Bile culture-directed therapy plays an important role in antimicrobial treatment.

This study examined the risk components and risk types perceived in the context of purchasing decisions of paper fashion products. This study also identified the levels of perceived risk by consumers and the differences between age groups in risk perception. First, qualitative data were collected through a focus group interview with 7 Korean females in their 20s to 50s. The interviewees were presented with two types of paper materials (undyed and dyed Jumchi-Hanji) and products (bags and wallets) made with the papers. The interviewees mentioned 11 risk components which were classified into five types of risks: performance (easily torn/lack of durableness, lint/pilling/wear-out, lack of water-resistant, no washability, and deformation and discoloration over time), social-psychological (old and traditional image), aesthetic (lack of design diversity, unsatisfactory appearance due to repair), financial (expensive price, lack of usability in daily life) and time/convenience (difficulty in handling) risks. Based on the results of the interview, a measurement for evaluating the risk perception of paper fashion products was developed. Second, quantitative data were collected from 64 Korean women in their 20s to 50s using the measurement. Respondents who were presented with the paper materials and the products perceived the performance risk more strongly than the social-psychological risk and aesthetic risk. In addition, differences between age groups were found: younger respondents perceived performance risk and social-psychological risk more strongly than older respondents, but older respondents perceived financial risk more than younger respondents. Based on this study, strategies for the risk reduction of paper fashion products were proposed.

Objectives: Chemicals derived from various environment media contaminates food across the food supply chain. In Korea, levels of contaminants in food have been sporadically measured by monitoring programs of different government agencies. There is difficulty with data compilation and integrated analysis across media. Therefore, the aim of this study was to propose an overall integrated database and analytical platform design for the 'ECO-FOOD NET (Environmental COntaminant reduction platform for FOOD through an interagency collaboration NETwork)', a tool to support the reduction of environmental contaminants in food. Methods: We developed a new data structure and standardized protocols for the compilation of integrated data. In addition, we conducted subject-oriented logical and physical relational database modeling and created the architecture design of the platform. Results: We established a standardized code system related to exposure media and route, analysis method and food matrix. In addition, we designed the seven software modules of 'About the System', 'Introduction to Interagency Work', 'Media-Chemicals Profiles', 'Method Bank', 'Monitoring Data Base', 'Integrated Media Analysis', and 'Risk-Benefit Analysis'. Conclusions: This study will contribute to decision-making as a tool for executing risk management, such as sustainable reduction policies of contaminants in food.

Background: Conservative treatment is performed for isolated anterior wall of the maxillary sinus fractures, in many cases when the fracture is clinically not severe and asymptomatic. Despite the absence of symptoms, complications such as sinusitis, rhinitis, and chronic purulent secretion may develop; therefore, successful reduction is required. We attempted to reduce the risk of complications using an alternative technique: reduction of the fracture with two urinary balloon catheters inserted through the maxillary ostium and fixation using fibrin glue, which minimizes the damage to the bony fragments and sinus mucosa. Methods: In this study, 38 patients who were diagnosed with an isolated anterior wall of the maxillary sinus fracture at our hospital between January 2014 and January 2017 were enrolled. The fracture site was exposed via the Caldwell-Luc approach followed by reduction through the insertion of two urinary balloon catheters using a nasal endoscope and fixation with fibrin glue. The sex, cause of fracture, physical examination, and presence of complications were examined and patient's medical records and facial bone computed tomography scans were analyzed. Results: Radiological evaluation showed that there was no evidence of collapsed reduction fragments. Although some patients had remaining symptoms of hypoesthesia (15%; 3 patients), there were no complications such as infection, rhinitis, sinusitis, and chronic purulent secretion at the surgical site. Conclusion: In this study, we present an alternative surgical technique using two urinary balloon catheters and fibrin glue for the successful reconstruction of an isolated anterior wall of the maxillary sinus fracture. This technique enables precise restoration with a reduced risk of complications.

This paper suggests an evaluation of risk level for damage of marine accidents in SRRs. Qualitative analyses in words is sometimes priorior to quantative analyses in numeric symbols. This paper intoduces a concept of fuzzy theory with the plenty of related literature riview and AHP in the Korean SRRs of RCC and RSC. The methodology of this paper is maxㆍmin composition of fuzzy extensive principle, defuzzifiation is centroid of gravity methods. At the result, the evaluation of risk level is especially over Serous for smarine accident of Taean, Gunsan, Mokpo, Yosu, Tongyoung, Busan SRR. This paper recommends that many Resale Vessels and Equipments need to the reduction of risk level about those.
