The application of cloud computing to many industrial domains is rapidly increasing, and domestic and foreign cloud service providers are actively conducting business. In the domestic cloud market, it is necessary to establish an ecosystem with partner operators that work closely with private cloud service providers. In this paper, to create such an environment, we propose a framework that can evaluate the capabilities of partners required for cloud service providers to establish specific business strategies. The framework proposed in this study establishes criteria for evaluating partners' competencies and applies a decision-making model such as fuzzy AHP for evaluation. Eventually this will help not only to expand the domestic cloud market but also to strengthen the competitiveness of domestic cloud partners through the growth of the domestic cloud market.

The toxics regulatory body provides a benefit/cost ratio as a justification criterion while implementing regulations that induce the industry to reduce emissions voluntarily. Furthermore, since, the body wants to reflect not only the efficiency standard but also the policy standard in the evaluation of feasibility, it calculates the ratio by adjusting the importance weights. The problem is that respondents answer ambiguously. It should be removed for the reasonable evaluation. This study introduced a fuzzy-AHP methodology for this, and applied it to the voluntary emission reduction plan program in Korea.

영국의 "기업과실치사법", 캐나다 및 호주의 기업처벌을 강화하기 위해서 형법을 개정하였음에도 불구하고 산업재해 감소 효과는 미미하다. 건설 현장의 불안전한 상태 방치 및 가설구조물에서 강도 높은 안전사고가 다수 발생하고 있다. 본 연구에서는 이러한 안전사고 예방을 위해 안전관리 실명제의 중요도 순위를 전문가 설문으로 도출하였다. 건설현장 전문가를 대상으로 AHP모형을 통해 중요도 분석한 결과 상위계층은 건설기계가 가장 중요하다고 보았으며, 하위계층의 안전시설물 관리에서는 개구부, 건설기계에서는 타워크레인, 관리실명제에서는 "산업안전보건법" 상에 의한 관리, 안전관리조직에서는 CEO의무가 가장 중요하다고 보았다. 안전관리실명제의 기대되는 역할은 중대재해처벌법이 예방에 힘쓰기 보다는 방어에 온힘을 다하느라 예방의 기능이 저하되고 있다. 이러한 역 기능을 바로잡기 위해 안전관리실명제는 중요하다.

1990년대 후반부터 Internet은 지식 정보 사회의 핵심 기반으로 급부상하면서 산업의 전 분야에 걸쳐 영향을 미치게 되었다. 이에 본고에서는 인터넷의 특성에 기인하는 여러 가지 현상들을 경쟁우위 변수를 선정하고 설문 조사를 통해 요인분석과 AHP(Analytic Hierarchy Process)의 쌍비교법을 이용하여 모델별 경쟁우위요소들의 우선순위를 도출하였다.

This study empirically analyzes the relationships among the road and traffic experts' personal characteristics, the driving behavior and factors being expected to have an effect on the satisfaction about roundabout operation. The factors are drawn and grouped through the principle component analysis to clarify driving environment satisfaction on roundabout operation. Each group is named as personal attribute, driving behavior attribute, and satisfaction. After the variables are refined by confirmatory factor analysis, satisfaction model is developed with personal attribute and driving behavior attributes as exogenous variables and roundabout driving awareness and emotion attributes as endogenous variables. As a result, driving satisfaction of roundabout operation is directly influenced by delay reduction, safety improvement, capacity increase, sight improvement, severity accident reduction, and bicycle convenience and indirectly gender, age, driving time, and driving experience. Law obeyance, driving concession, traffic sign obeyance, and interposition do not statistically shows significant on satisfaction. As a result of Analytical Hierarchy Process (AHP), the turning radius of geometry and the driving behavior are important elements for roundabout safety.

As many stakeholders are taking part in the Housing Redevelopment Project, their opinion mediation is considering very important issues. Thus disputes on projects are inevitable due to complexity of interest. To effectively progress the project, this paper analyze the risk factors by phase in implementation phase that the association participates in person. We identify 50 of risk factors in implementation phase by reviewing and analyzing related studies and actual cases of disputes, then we present 26 of risk factors through experts interview. Also, we calculate weights of risk factors by using AHP for quantitatively analyzing them and present final weights and priorities of risk factors by summing weights of risk factors by phase. In results, it is found that 'the inappropriateness of the Management Disposal Plan' in management disposal plan phase and 'the inappropriateness of the Project Implementation Plan' are the most significant risk factors. To maximize the utilization of risk factors analyzed, we present the checklists that can be aware of these risks in advance and prevent these risks. Based on these findings, if risk factors in implementation phase are managed actively, the housing redevelopment project will be performed more effectively.

Rail transportation system are needed to develop proper corresponds to satisfy various demands in freight transportation since there are many problems in rail transportation infrastructure and operation. This paper analyzes characteristics of rail transportation consumers and develops policy for vitality of rail transportation by survey of rail transportation consumers and AHP methodology. This paper is organized as follows. Section 1 presents the description of the objective and the methods for this study. Section 2 presents the description of the methods for analysis of characteristics of consumers of rail freight transportation. Section 3 presents the characteristics of rail transportation consumers by analysis the survey results of rail transportation consumers. Section 4 summarizes our conclusions and discusses further research topics.

At present, CPTED projects are showing an effect such as reducing the anxiety of residents from crimes and improving the criminal environment about crimes through crime prevention. However, most of the CPTED programs have been implemented mainly to improve the physical environment without verifying systematically and empirically on the relationship between the program and improving the quality of life of residents and satisfaction level of residents etc. Accordingly, the objective of this study is to grope for a plan to apply CPTED to urban regeneration for improvement in the safety and life quality of residents using AHP and Visualizing The Mental Map. For this, We selected four case areas in Busan and then analyzed the dead zones of CPTED programs by visualizing the mental maps and heat maps of residents for case districts. As a result of evaluating the priority of CPTED program, installation of CCTVs and streetlights for prevention of crimes was found to be the most important elements. Result of analyzing mental map, the existing crime prevention facilities and CPTED programs were found to have resolved most of physical disorder. However, it showed that, for psychological factors which the residents feel such as social disorder, a number of dead zones exist.
