Given the few studies on the responsibilities of assembly, government, and president for social conflicts, this study analyzes the influence of conflict causes upon that responsibilities. First, the need for the mediation mechanisms for dealing with social conflicts and the level of labor-management conflict are positively associated with the responsibilities of assembly, government, and president. Second, the levels of conflict between social strata and ideological conflict are positively related with the responsibility of assembly or president. Third, interdependence and mutual understanding between stakeholder, among independent variables, are positively associated with the responsibilities of assembly and president. Finally, all of the levels of conflict types, except the level of ideological conflict, moderate the effects of conflict causes on the responsibilities of assembly, government, and president. These results reflect the importance of managerial and institutional approaches to the conflict resolution focused on conflict causes and types.

Server virtualization provides abstraction of physical resources to users and thus accomplishes high resource utilization and flexibility. However, the characteristics of server virtualization, such as the limited number of physical resources shared by virtual machines, can cause problems, mainly performance interference. The performance interference is caused by the fact that the CPU scheduler running on the host operating system schedules virtual machines without considering the characteristics of the virtual machine's internal process. To address performance interference, a number of research activities to improve performance interference have been conducted, but do not deal with the fundamental analysis of performance interference. In this paper, in order to analyze the cause of performance interference, we carry out profiling in a variety of scenarios in a virtualized environment based on KVM. As a result, we analyze the phenomenon of the performance interference in terms of CPU scheduling and propose an efficient scheduling solution.

The continuous fatal accidents like explosion or fire cause huge losses of both life and property in laboratories even though safety management system has been built and periodical checkups and safety diagnosis have been implementing in universities and enterprise-affiliated research institutes since Act on the Establishment of Safe Laboratory Environment was enacted in 2005 to prevent accidents in research laboratories. Cause analysis and safety management measures to prevent recurrence of accidents are urgently needed because accidents in research laboratories occur repeatedly with similar contents. This study will show results of analysis on incidents and accidents occurred in laboratories in universities and enterprise-affiliated research institutes using Root Cause Analysis Method and propose classified map of cause investigation and improvements so as to improve safety management in research laboratories.

이동전화시장에 경쟁된 이후 국내 이동전화시장은 사업자간의 치열한 경쟁으로 인해 보급률이 58%에 달하는 등 급격한 성장을 이룩하여 왔다. 그러나 이러한 외형적인 성장에 비추어 이용자 입장에서의 경쟁 활성화 효과는 극히 미미한 실정이다. 오히려 이동전화서비스에 대한 소비자들의 불만이 갈수록 높아지고 있는 것으로 나타났다. 이러한 문제의 근본 원인은 이동망을 운영하고 있는 사업자들이 일단 가입자가 확보되면 확보된 가입자에게는 거의 독점적인 권한을 행사할 수 있는 시장구조에서 비롯되고 있다. 본 고에서는 이러한 이동망의 배타적 사용문제를 해결하고 경쟁을 활성화하기 위한 수단으로써 가상이동망사업자(Mobile Virtual Network Operator: MVNO) 제도를 검토하고 그 구체적 운영방안을 외국사례를 중심으로 살펴보고자 한다.

중수형 원전과 경수형 원전의 핵연료 교체방식, 핵연료 특성, 원전에 설치된 사찰장비 등의 안전조치 특성 관점에서 비교 분석되었는 바, 이는 중수형과 경수형 원전에 투입되는 사찰량의 차이가 10배 이상 투입되는 근본적인 원인으로 파악되었다. 특히 사찰량의 비교를 위하여 사찰시 수행되는 단위활동별로 소요시간을 측정하여 향후 국가 계량관리 검사 수행시 사찰량을 절감할 수 있는 요소들을 정확히 파악하여 사찰량 절감방안을 도출하는데 기여할 것으로 기대된다. 또한 우리나라가 보유하고 있는 원자력발전소 유형인 중수형과 경수형 원전에 대한 안전조치 측면에서의 특성을 상호 비교함으로써 안전조치 접근방법에 정확한 이해와 국가 계량관리 검사절차서의 개선에 기여할 것으로 기대된다.

해상교통사고의 가장 큰 책임은 사람에게 있기에 사람이 발생시킬 수 있는 사고의 요인을 명확하게 파악하고 선별할 수 있는 대책을 마련할 필요가 있다. 특히 사고를 발생시키는 근본적인 원인은 개인 스스로도 지각하지 못하는 적성상의 결함요인에 의해 발생할 가능성이 높다. 따라서 사고의 예방을 위해 개인의 적성에 대해 명확히 개념화 하고 측정하여 관리할 필요가 있다. 본 연구에서는 항해사의 적성검사도구 개발을 위한 기초연구로서, 항해사 개인특성에 대한 사전연구 분석, 전문가 회의 및 설문조사 결과를 종합하여 항해사의 사고경향성 평가요인을 선정하고자 하였으며, 이를 기반으로 항해사의 사고경향성을 평가할 수 있는 항해사 적성검사도구의 프로토타입을 개발하고자 하였다.

Basic function of calorifier system is to supply warm water to the vessel. The heater used in the calorifier system plays a very important role in its reliability. The failure mechanism of heater are compared with accelerated life test. The main cause of failed heater is pitting corrosion occurred between the surface of heater and spacer. To prevent the corrosion failure from heater, material of spacer replaces metal(SUS 304) with polymer (Acryl). The life of redesigned heater can guarantee 2.47years of B10 life under the worst condition.

This study examined the background of the recent global financial crisis and the concept of one of the financial derivatives such as the credit default swap(CDS) or synthetic CDO(collateral debt obligations), given the rapid growing and changing the over-the-counter derivative markets in their volume and structures. In comparison with the previous literature such as the study of Park & Kim (2011), this research empirically performed more thorough and comprehensive investigations to find any financial characteristics or attributes to determine the CDS spreads. Regarding the results obtained from the multiple regression models, the explanatory variables such as STYIELD3, SLOPE, INASSETS, and VOLATILITY, showed their statistically significant effects on all the tested dependent variables(DVs). Another procedure such as the principle component analysis(PCA), was also performed to account for additional IDVs as possible determinants of the dependent variables. Subsequent to this analysis, larger coefficients of each corresponding eigenvector such as BETA, PFT2, GROWTH, STD, and BLEVERAGE were found to be possible financial determinants. For robustness, all the IDVs were employed to be tested in the 'full' regression model with stepwise procedure. As a result, STYIELD3, SLOPE, and VOLATILITY, and BETA showed their statistically significant relationship with all the dependent variables of the CDS spreads.

Three failure cases of CNG composite vessels were reported since after January 2005. The 1st and 2nd accidents were indebted to vessel defect and installation mistake. The 3rd was caused by gas leak at pipe connections. In this paper various aspects were studied based on information of the three failure analysis, which must be improved for better safety of the CNG bus system. Overpressure region caused by vessel explosion was theoretically predicted and also assessed by PHAST program. Explosion of 120 l vessel under 20 MPa is equivalent to 1.2 kg TNT explosion. The predicted value by PHAST was more serious than theoretical one. However, actual consequence of explosion was much less than both of the predicted consequences. Since the CNG vessel was designed by the performance based design methodology, it is difficult to verify whether the required process and tests were properly conducted or not after production. If material toughness is not enough, the vessel should be weak in brittle fracture at early in the morning of winter season since the metal temperature can be lower than the transition temperature. If autofrettage pressure is not correct, fatigue failure due to tensile stress during repeated charging is possible. One positive aspect is that fire did not ocurred after vessel failure. This may be indebted to fast diffusion of natural gas which hindered starting fire.
