  • In this study, the author apply the VLF(Very Low Frequency) tan-delta data that has been measured at each office of the KEPCO 2012 to the Weibull distribution which is the statistical analysis as previous studies for the remaining life prediction through the improvement of the sensitivity and reliability of the degradation state assessment of underground distribution power cables. Also, in this paper, UCD(Used Cable Diagnosis) Matrix proposed by KEPCO was applied to the hierarchy of assessment prioritization. it suggests Aging Index for condition assessment and high reliability of proper economic replacement cycle using the weight according to the assessment prioritization.

  • Evaluating environmental impacts of regional development projects has critical importance in environmental management aspect. This paper uses multi-attribute utility theory as a basis for obtaining a value index to assess the environmental impacts and applies the theory to a specific Korean case study. To structure and quantify basic values for the assessment, we elicited important attributes, then refined and structured them into a hierarchy. An environmental multi-attribute index is constructed as a multi-attribute utility function, based on value judgments provided by a group of technical experts, policy makers, and a decision-maker at Korean Ministry of Environment. The implications of the results are also discussed. We found that the work and results can provide valuable insights for assessment of environmental consequences.

  • In an effort to analyze the impact of climate change, Gangwon provincial forest was divided into three sectors; forest ecology, forest disaster, and forest productivity and analysis of their current status from 2000 to 2009 and vulnerability assessment by climate change has been carried in this study. In case of vulnerability assessment, except for the forest ecology, forest disaster (forest fires and forest pests) and forest productivity sectors were analyzed in current status, the year of 2020, and 2050. It turned out that vulnerability of forest fires in the field of disaster would become worse and forest pests also would make more impact even though there is some variation in different areas. In case of the vulnerability of forest productivity there would be not a big difference in the future compared with current vulnerability. Systematic research on the sensitivity index used for vulnerability assessment is necessary since vulnerability assessment result greatly depends on the use of climate exposure index and adaptive capacity index.

  • Purpose: The purpose of this study was to develop a program outcomes assessment system based on Course Embedded Assessment for nursing education. Methods: This study was conducted in accordance with the procedures of the developmental research method. Results: The major results are as follows. 1) The program outcomes were measured according to the Analytic Hierarchy Process. 2) The Course Embedded Assessment matrix was made according to program outcomes' weight, the curriculum-organizing principle, and achievement levels. 3) The Course Embedded Assessment rubric was developed in logical process, and consisted of a performance criterion, and rating scale. The content validity index of the Course Embedded Assessment rubric was 0.85. 4) An evaluation guideline and 12 documents were developed to facilitate the performance of the assessment system. 5) The average content validity index of the Course Embedded Assessment-based program outcomes assessment system was as high as 0.89. Conclusion: A Course Embedded Assessment-based program outcomes assessment system is more suitable for accreditation of nursing education than previous studies. Because this system evaluates the process of achievement as well as program outcomes, the results can also serve as immediate feedback to improve the educational process. Above all, this system facilitates that students check their achievements and strive to acquire core competencies in nursing.

  • Coastal sand dune systems are particularly fragile and threaten the environment. However, these systems provide fundamental ecosystem services to the nearby urban areas, acting, for example, as protective buffers against erosion. In this paper, we attempt to classify the biotope types of coastal sand dune ecosystems and select an index for the assessment of the conservation value. The types of biotopes are categorized based on the vegetation map; floras are examined in order to research the effects of hinterlands on coastal sand dunes. In addition, a naturalization rate and an urbanization index for each biotope type in hinterlands are analyzed. In the ecosystem of coastal sand dunes, the urbanization index and naturalization rate shows a higher value in sand dunes with areas of road, residential, and idle land in farm villages, rice fields, and fields. On the contrary, a lower value in the urbanization index and naturalization rate is present when typical biotope types, such as sand dune vegetation and natural Pinus thunbergii forests, are widely distributed. Based on these results, urbanization index and naturalization rate should be used as critical indices for the assessment of the ecosystem of costal sand dunes.

  • In this paper, we developed a workload index for monitoring the durability test using operation information of an excavator. First, the acceleration and cylinder pressure were selected as load factors by analyzing operation data. Through load correlation analysis according to each load factor, Root Mean Square (RMS) and Work Load Range (WLR) were respectively derived as a load feature representing mechanical load. In addition, the workload index was used to quantify load features. For applying the workload index to monitoring, a real-time monitoring system consisting of sensors and embedded controller was installed on the excavator and the system was integrated with a remote monitoring environment using a wireless network. Results of load monitoring and analysis verified that the developed workload index was effective from the viewpoint of the relative comparison of the workload.

  • This study proposes the introduction of management assessment system on the remote island route passenger companies in a way of stimulating the companies to make sustained efforts on management improvement, and come up with the ways of management assessment index and management assessment methods by using the AHP scheme. These indices are organizes in three categories. The main category is consisted of responsible management part, management an control part, business operation part and customer satisfaction part, and the intermediary category has the 15 items including the efforts for responsible management, and the sub category is consisted of 44 items including the management vision of executive and participation of enterprise in responsible management, and others. The scoring of these indices is the result of scoring by calculating the added weight for each category by using the AHP scheme that it is considered as needed for the scoring adjustment for each standard of assessment index by the adjustment of added weight for categories with the consideration of shipping company operation and shipping characteristics while undertaking the actual affairs.
