국가 재정사업을 평가하는 재정사업 자율평가제도는 2005년에 도입되어 2010년까지 두 번의 평가주기가 완료되었다. 본 연구는 이러한 시점에서 2차 평가주기(2008년~2010년) 동안 평가된 재정사업을 대상으로 평가결과에 영향을 미치는 요인들을 검토하였다. 본 연구는 1차 평가주기(2005년~2007년)의 평가결과를 분석한 기존 연구의 확장연구로서, 이전 연구결과를 재확인하고 일반화 가능성을 보다 제고할 수 있을 뿐만 아니라 이전 연구결과와의 비교를 통해서 평가제도의 변화가 평가결과의 변화를 가져왔는지를 검토할 수 있다는 점에서 의의가 있다. 또한 2차 평가주기가 완료된 시점에서, 향후 제도 개선을 위한 정책적 시사점을 줄 수 있다는 점에서 의의가 있다. 본 연구의 주요 분석결과 및 정책적 함의는 다음과 같다. 첫째, 1차 평가주기에 비해서 2차 평가주기의 평가결과가 향상되었다는 점에서 사업의 성과향상 또는 제도에 대한 실무자들의 이해가 보다 증진된 것으로 해석할 수 있다. 둘째, 성과계획항목이 평가결과에 지나치게 강한 영향력을 준다는 측면에서, 이에 대한 제도적 보완이 요구된다. 성과지표의 설정 및 목표치의 결정은 집행 이전에 적절히 이루어져야 할 부문이기에 이를 계획수립 시 사전적으로 지도할 필요가 있다. 셋째, 집행항목과 성과항목 간 부(-)의 관계를 가지므로 이에 대한 적절한 제도적 보완이 필요하다. 넷째, 제도의 타당성을 저해할 수 있는 비평가요인이 총점에 영향을 미치고 있다는 점을 감안할 때, 이에 대한 제도적 보완이 필요하다.

The purpose of this study is described in detail as follows. First, I would like to define what digital transformation is in the maritime transport sector. Second, it is intended to derive success factors for digital transformation in the maritime transportation field by examining various preceding studies related to digital transformation. Finally, in order to derive priorities for the derived success factors, an AHP analysis model is built and an expert survey is conducted for practical experts in the maritime transportation field. Based on the survey results, we would like to provide guidelines on what factors should be considered first among the success factors of digital transformation in the maritime transportation sector. In this study, in order to derive the priority of success factors for digital transformation in the maritime transportation field, the hierarchical structure was divided into four high-level evaluation items(strategic factors, organizational culture and human factors, technology factors, and environmental factors) and 21 sub-evaluation items. A relative evaluation method of weighting items among AHP(Analytic Hierarchy Process) was applied. AHP analysis of 24 questionnaires with a consistency ratio of 0.1 or less in order to increase the accuracy of information among questionnaires collected through maritime transportation related university professors, research groups, shipping companies, container terminals, and experts engaged in shipping related IT companies was carried out. As a result of the analysis, the priority of the first-tier factors for the success factors of digital transformation in the maritime transport sector was shown in the order of strategic factors, organizational culture and human factors, technology factors, and environmental factors. In addition, when looking at the priorities of 21 detailed items, it was found that the development of new business models, the creation of an active future digital strategy, and the leadership of the chief digital officer were high.

This research has developed the criteria and index for systematically and objectively assessing the quality of river water by fixing the various factors that affect Gyeongin ARA waterway's water quality through analysis with the Delphi Technique and analytic hierarchy program (AHP) Method. Based on the results, the highest criteria are, in order of importance, physical and environmental factors 28%, administrative factors 26%, natural fixed factors 26% and finally, cultural and social factors 20%. The three dimensions of the criteria show that for the internal physical and environmental factors, the most important are the loss of self-purification capacity, and the external factors are Gulpocheon and the sludge deposit due to Gyulhweon-weir the bridge. The facility factor in management was affected by the coagulation and waste water disposal facilities. The problem for the policy and institutional factors was seen in the regulatory area. The aquatic ecology/ point pollution source for the natural fixed factors show that it is due to the polluted water of Gulpo-cheon and the living environment/ non-point pollution source is shown through the inflow water from other rivers. Cultural and social factors show that the economical causes were due to the cargo and passenger flight operations and the external factors of having a lack of sewage treatment equipment have an importance effect. In order to estimate the order of priority through logical evidence and objectivity, future research must be continued on the evaluation indexes to measure the specific methodology and technique needed to improve the Gyeongin ARA Waterway.

This study was carried out to provide basic data for efficient park management by analysing visitors' satisfaction factors and estimated regression model through questionnaire survey method at Taeanhaean National Park in Korea. Performance(satisfaction) variables as 'touting', 'illegal merchant', 'noise', 'indiscreet use' and 'collection of natural plants or animals', and Importance variables as 'littering problem', 'water pollution act', 'careless cooking' and 'exorbitant pay' were relatively high score. It was clarified that the 'souvenir & special product', 'lack of use program' 'lack of public facility', 'lack of information facility', and 'lack of commercial facility' were 'concentrate here' ones by the Importance-Performance analysis. 'Facility management', 'Use management' and 'Resource management' factors were found out by Factor Analysis and the 'Facility management' was the biggest factor accounting for 32.6% of all. In the estimated model by Multiple Regression Analysis, 'lack of employee's guidance or kindness', 'lack of convenience facility', 'noise', 'lack of facilities to stay' and 'charge of user fee, parking fee' were the variables to impact visitors' satisfaction and to need concentrated management. These results were unique characteristics of marine national park and then the different management strategy and policy from mountain national park were necessary.
