The landslide occurrence in Sam-Chuck area was analyzed through Geo-Spatial Information System and AHP(Analytic Hierarchy Process). Among many factors which causes landslide, terrain slope, terrain aspect, lithology, soil texture and vegetation arc taken as input data from existing maps and constructed as a database. These factors are determined by each environmental factor by environmental and geological characters in the study area, and the rating and weight about factor are input using AHP. Possible areas for landslide have been extracted by overlaying each layers. Finally, the estimated results are compared with real landslide sites to know which factor is the most effective for landslide. The results showed that lithology and soil factor have high susceptibility in Sam-Chuck area.

The purpose of this study is to present the application of Information and Communication Technology(ICT) during the 4th Industrial Revolution for the efficient implementation of government emergency preparedness policies. Brainstorming by experts categorized the government's emergency preparedness policies into 4 types and 12 detailed tasks. Classification results were used by AHP(Analytic Hierarchy Process) to analyze relative importance and priorities. The AHP survey found that strengthening crisis management responsiveness was the most important detailed task. Artificial Intelligence(AI), Internet of Things(IoT), Unmanned Autonomy System, Virtual Reality(VR), and Augmented Reality(AR) were presented as major information and communication technology(ICT) for the efficient execution of detailed tasks.

Recently, many internet users are using cloud computing. Users can manage, store and share their data and information by using personal cloud storage. In this paper, we aim to figure out influencing factors on personal cloud storage selection. The causal relationship between factors were identified through a importance analysis by using AHP(Analytic Hierarchy Process). AHP is a structured technique for organizing and analyzing complex decisions, based on mathematics and psychology. Research model consists of upper factorsincluding system factor, service factor and user factor. 12 lower factors and 6 alternatives were also analyzed. Asa result, system factor of 3 upper factors was found as the most important factor. Purpose-coincidence, security andaccessibility were top 3 factors among lower factors. N drive showed top importance value. We also conducted ANOVAby classifying 4 groups according to gender, age, currently used cloud and cloud to use. The results of this researchcan be useful guidelines for cloud computing industry.

This study generalized and systemized the unit-project items of 176 project districts for the rural village comprehensive development projects (RVCDP). This paper surveyed opinions of III answerers (7 specialists, 43 agents of Korea Rural Community corporation, and 61 agents of local government of cities and counties) in order to determine the classification system and their corresponding weighting values of the project items using analytic hierarchy process (AHP) method. From the results extracted by project plans of 176 project districts for 5 years from 2004 to 2008, this study decided a hierarchical system for unit-project items of RVCDP by AHP method, which consisted of three steps: 4 items for 1st step, 13 items for 2nd step, and 52 items for 3rd step. The first step contains 4 items of Strength of Rural-urban Exchange & Regional Capability (RURC), Green-income Infrastructure & Facility (GIF), Culture-health-welfare Facility, and Eco-environment & Landscape facility (ELF). In the survey of weighting values with AHP method, the analysis result for the first step showed that in opinion of specialists, GIF is more important than the others while in opinion of the other agents, RURC is more important. In the second step, Product Facility is more important in the specialists, whereas Strength of Resident Capability is the most important in the other agents. Analyzed unit project items as the third step, all answerers evaluated that the Education and Excursion for Rural Resident Capability has the highest weighting values.

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.

There are rule-based learning method and statistic based learning method and so on which represent learning method for hierarchy relation between domain term. In this paper, we propose to leveling and similarity measure using the extended AHP of fuzzy term in Information system. In the proposed method, we extract fuzzy term in document and categorize ontology structure about it and level priority of fuzzy term using the extended AHP for specificity of fuzzy term. the extended AHP integrates multiple decision-maker for weighted value and relative importance of fuzzy term. and compute semantic similarity of fuzzy term using min operation of fuzzy set, dice's coefficient and Min+dice's coefficient method. and determine final alternative fuzzy term. after that compare with three similarity measure. we can see the fact that the proposed method is more definite than classification performance of the conventional methods and will apply in Natural language processing field.

Even though the pre-feasibility study was introduced in 1998, it mainly has focused on transportation social overhead capital(SOC) such as road and railroad. Last year, however, the government newly launched R&D project area for the pre-feasibility study. This paper tries to analyze the pre-feasibility study methodology and system that applied to R&D facility, cluster, and sized R&D infrastructure projects. In depth study of economic, policy, and AHP analysis, this paper shows that the preliminary feasibility study have some caveats and suggests a way of improvement for making up for limitation. Main suggestions are as follows; First, to improve the fit in R&D sector analysis, using consistent method is important. Second, technology analysis is essential for R&D evaluation. Third, technology experts should take part in AHP analysis.

There are various types of PLM(product liability management) according to corporation management level. It is necessary to develop diagnostic methods and application systems for PLM as well as to establish an efficient PLM system. This paper aims to propose a PLM system which can be applied to product with high-reliability and high-safety, and diagnostic methods for PLM based on AHP, and also show an empirical application of the proposed PL management system for Auto Test Robot System of the Mobile Phone (EVT 4320).

Blockchain was proposed in 2007 and began to be applied to actual services soon afterward. The railway system covers railroad construction and railway services. Because of the public characteristics of the railway system, it is expected that significant advantages can be obtained through the introduction of blockchain. Many benefits can be gained by applying the blockchain to them, but it is impossible to apply the blockchain to every part immediately due to the limitations of time and resources. Therefore, it is necessary to derive services or functions to which the blockchain will be applied and to select the part of them first. Since there are various evaluation criteria to derive the priority of blockchain adoption, systematic consideration is required. In this study, AHP was applied to calculate weights for evaluation criteria and systematical evaluation. Through the results of this study, it is expected that it is possible to build a roadmap for a next-generation railway system.
