이전 필름 카메라 시대에는 한 필름에 촬영 가능한 사진의 수가 제한되고 인화와 현상에 대한 비용과 시간 소모로 인해, 꼭 필요하거나 중요한 순간에 사진을 촬영하였다. 그러나 최근에는 디지털 카메라의 보급과 대용량화된 메모리로 인해, 이전의 필름 카메라 시대와는 달리 일반 사람들도 한번에 많은 양의 사진을 촬영하는 일이 많아졌다. 이와 같이 관리해야 할 사진의 수가 많아질수록 사진을 분류하고 관리하는 작업에 많은 노력과 비용이 소모된다. 본 논문에서는 윈도우와 우선순위 큐를 이용하여, 촬영시각 문맥 (temporal context)의 흐름이 약한 순서대로 사진들을 클러스터링하는 방법을 제안한다. 제안한 방법의 평가를 위해서, Cooper 가 제안한 이벤트 클러스터링 방법과 정확도와 재현율을 비교하였으며, 사진 촬영 시각 차이의 분포의 편차가 작을수록, 제안한 클러스터링 방법이 높은 정확도를 보였다. 본 논문에서 제안한 촬영 시각 클러스터링은 많은 수의 사진들을 이벤트 기반으로 자동 분류하는데 활용될 수 있으며, 클러스터링된 정보들을 그룹별로 시각화하기 위한 인터페이스를 개발하는 것을 향후 연구과제로 제시한다.

Due to the deterioration of infrastructure, the importance of maintenance is continuously increasing. Therefore, an integrated maintenance method for various facilities is required. In this study, a maintenance priority determination method for integrated maintenance of roads and pipe network facilities was developed. It is possible to analyze attribute information by using GIS data of roads and pipe networks, and shape information can be used. This information is derived as quantitative figures for determining maintenance priorities. In the future, it is expected that facility maintenance can be further advanced in connection with maintenance method and quantity information for each facility.

The purpose of this study is evaluate factor for risk management of hazardous substance at ports. The analysis was conducted by applying Fuzzy-AHP methodology, through a questionnaire for hazardous substance experts from Busan, Gwangyang, Incheon, and Ulsan, which are the major Korean ports. Three measurement areas and nine sub-factors were selected for the study. The results of this analysis showed that "human resource management" (HR) was the most important factor (0.445) in the three measurement areas. After applying the conversion weight, the sub-factors were ranked according to their priority as follows: "a secure of administrator skill" (0.158) had the first rank, "an improvement in administrator duty" (0.150) had the second, and "consolidation of safety education" (0.136) had the third rank.

The trade deficit in mushrooms has continued to increase in recent years. This study explored major issues and challenges faced by the mushroom industry to increase export, and to prioritize the current issues and challenges based on their relative importance. 11 major issues and challenges in the mushroom industry were highlighted in focus group interviews. Best-worst scaling analysis prioritized these major issues and challenges, and questionnaire surveys were completed by 31 mushroom industry experts. The results revealed that strengthening the mushroom quality and price competitiveness were the main priorities, followed sequentially by a diversification of the overseas export markets and stabilization of the domestic mushroom price.

Variable speed limit(VSL) is a useful speed management tool for alleviating traffic congestion and enhancing traffic safety. The purpose of this study is to identify promising freeway segments for safety enhancement through VSL operations. An ordered probit model was adopted to capture factors affecting freeway crash severity that can be used to support decision making for selecting the promising segments. Pseudo elasticity and marginal effects, which are outcomes of the ordered probit analysis, were used to determine priority of promising segments for traffic safety. The results of this study would be useful in installing VSL systems and developing traffic control and operations strategies in practice.

This study aims to support rational security investment decision making through prioritizing on operational level of management measures strategically, in carrying out industrial security activities. For this, AHP survey is conducted against industrial security professionals and analyzed. Thereafter, the importance and the priority of industrial security management measures are determined. As a result, in a comparison evaluation among the criteria, 'ICT service management' represents the highest weight (0.54). And the sub-criteria could be divided into three groups (Group I, II, III), depending on their importance. The sensitivity analysis results show that if the weight of the criterion, 'ICT systems/networks access control' is doubled, the sub-criteria, 'O/S access control', 'application access control', and 'wired/wireless network access control' are enter into top rank group. In case of the criterion, 'physical/environmental security' is doubled, the sub-criteria, 'protection zoning/access control' and 'disaster prevention on business equipment/counter-terrorism' are enter into the top rank group, 'securing utilities' is enter into the mid rank group.

In those day, the Busan local government had instituted a rule to support and enhance competition as well as improve respect for the ship management industry. This study aims to extract the cause factors to enhance such competition using intuitionistic decision making trial and evaluation laboratory (DEMATEL) and interpretive structural modeling (ISM) methods. First, eight factors were extracted from the specifications in the Ship Management Industry Development Act. Second, the intuitionistic fuzzy number was converted to a crisp number using the standard fuzzy number. Third, the influence relationship was analyzed using DEMATEL, and the priority ranks for the factors are determined using ISM. From the results of the impact relationship analysis, the three main cause factors were determined as improvement of technical ship management capability, improvement of expertise of manpower for onshore management, and improvement of the quality of the Korean seafarer. The priorities under the ISM method, in descending order, were as follows: improvement of the quality of Korean seafarers, improvement of professionalism among the manpower for shore management, improvement of technical ship management capability, improvement of commercial ship management capability, establishment of a comprehensive information system, improvement of the working conditions and employment environment for seafarers, financial support such as overseas orders, and strengthening the availability of foreign seafarers. Therefore, it is necessary to prioritize policy promotion based on these factors, especially the top three, as these have the highest impact.

This study was based on the research contents of previous studies. and After operatively defining public culture and arts institutions in terms of combining the characteristics of public institutions and culture and arts, the necessity of analyzing the priority of performance evaluation indicators was raised in accordance with this. The results of priority analysis based on the AHP axiom are as follows. The priorities for the performance evaluation index of public culture and arts institutions were in the order of artistry, expertise, marketing, publicity, organizational management, exchange and cooperation, management efficiency, operating system, and convenience. Based on the analysis results, the following implications were presented. First, it is necessary to first pay attention to the items of artistry that appear as the highest priority and seek strategies. Second, it is necessary to put a variety of experts in the original plan so that the audience and the public can have a high interest in this. However, in order not to exceed the 10 items recommended by the AHP axiom, we had to intentionally limit the evaluation items. Therefore, it is necessary to analyze priorities by deriving various evaluation items in subsequent studies.
