As the social interest of the Baby Boomer generation is increasing, this study derives implications for lifelong education policy through identification of the need and support for lifelong education among baby boomers lifelong learning, taking into account such aspects of quality of life as emotional psychology-based self-development and self-realization. To optimally explore support for lifelong learning for the baby-boomer generation, first-tier (top-level), sixth-tier (bottom-level), and five-other evaluation criteria were available. For the first layer, we examined whether potentiality or realizability was more desirable, and for the second layer, detailed criteria for realizability were set up, dividing them into financial, legal, and administrative feasibility. A study conducted by experts on the policy priority analysis of Baby Boomers showed that their support for lifelong learning places a greater priority on its feasibility (the more feasible alternative) than desire (the more desirable option). Among the six criteria, lifestyle activities had high priority, and the relative importance of the five assessment alternatives for lifetime learning activities was shown to be higher for employment skills education (0.377), civil participation education (0.181), lifestyle activities (0.200), and 'lifetime activities' (06.11). These results are meaningful: they can help shape and refine the needs of lifelong education, assess their relative importance, and prepare basic data for lifelong learning policies for baby boomers who are about to enter their old age.

This research is the study on the comparative evaluation of SPC (Staggered Pedestrian Crossings) vs PC (Pedestrian Crossings) using risk analysis. Accident factor was elicited by survey of driver's and pedestrian's at SPC & PC. I estimated the weight of a risk of violation and a mental burden by AHP (Analytic Hierarchy Process) and compared degree of risk at SPC AND PC. In conclusion, a new alternative plan of a pedestrian crossing system, staggered pedestrian crossing which plays an important role in traffic flow, pedestrian's crossings which plats an important role in traffic flow, pedestrian's convenience and traffic safer is sager than pedestrian crossings the degree of risk used this study doesn't imply an measure of the number of accident and the rate of accident, in estimating the degree of risk of pedestrian crossings, we should analyze more data of accident, behaviors, and road circumstance to include driver's and pedestrian's violation behavior in an estimate index.

By applying the AHP(Analytic Hierarchy Process), we have analyzed the importance and the order for priorities to the management risk factors of Korean SMEs & Venture companies in China. The major management risk factors of manufacturing companies were the rise in labor costs followed by fierce competition in the marketplace, problems involved with human resource management and the rise in the cost of materials. In the case of companies manufacturing electronic products, the rise of labor costs and alteration in government's tax policy were seen as the main risk factors. In the case of chemical product manufacturing companies, the reinforcement of environmental protection law and in automobile component manufacturing companies, apart from the rise in labor cost, the increase in raw materials costs were analyzed as the main risk factors. While considering the time period, the main risk factors of the companies that entered China in the 1990's were fierce competition and alteration in government's tax policy and for the companies that entered China in the 2000's, increase in raw material cost, the rise in labor cost etc were analyzed to be the main risk management factors.

Truck platooning, which is a cluster of trucks in support of vehicle-to-vehicle communication and automated longitudinal vehicle control, is a promising method to both operational efficiency and prevent traffic crashes. Although a variety of studies have been conducted to identify the effects of vehicle platooning on traffic stream, we are not aware of any study attempting to identify promising road segments for vehicle platooning. This study aims to develop a methodology for determining the priority of freeway segments that would potentially lead to maximize the effectiveness of truck platooning. Evaluation measures derived in this study includes truck crash rates, the percentage of truck traffic, segment length, and the number of entry and exit points. Weighting values obtained from an analytical hierarchical process (AHP) method were applied to compute the proposed priority score to determine better freeway segment for truck platooning. Results suggested that a 46.9km freeway segment, from Sacheon IC to Sanin JC, was the most promising segment for maximizing the effectiveness of truck platooning. It is expected that the outcome of this study would be effectively used as a fundamental to establish operational strategies for truck platooning.

To increase port productivity and efficiency and also to avoid disadvantages of public port management, a port authority system h1s been introduced worldwide. The Korea Port Authority Act was enacted in 2003 and Incheon Port Authority was established in July 2005. The objective of this paper is to develop a strategy of Incheon Port Authority using SWOT/AHP method Research findings show that possibilities of business expansion and growth as well as geographical advantages of Incheon Port are identified as its strength The opportunities of Incheon Port Authority are continuous increase of cargo handling volumes in the Yellow sea rim and expansion of Free Trade Zone. A government two-port policy and growing its dependence on China and rapid growth of more competitors in domestic and overseas are considered to be threat. Its weaknesses include superannuated Incheon port facilities and port hinterland shortages. Based on SWOT analysis combined with AHP method this paper suggests S/O strategy, W/O strategy, S/T strategy, and W/T strategy as a strategic development plan of Incheon Port Authority.

Recently, the automobile industry is rapidly changing due to autonomous vehicles based on advanced ICT technology. As a result, studies related to autonomous vehicles have also been actively conducted. However, most studies are focusing on the autonomous driving technology so that the prediction of changes in road traffic safety and associated legal system due to the introduction of autonomous vehicles are lacking. The purpose of this study is to suggest improvement methods and priorities of road traffic safety projects according to the introduction of autonomous vehicles. As a result of the AHP analysis using the results of the questionnaire surveyed for autonomous driving car experts, it was analyzed that revision of the traffic safety inspection law and development of education system for autonomous driving motor drivers and operators should be given top priority.

During the development process of mega-project, individual buildings including skyscrapers are built following the master plan. It is not a difficult thing to see the gap of standpoint between the urban planners and architects on the project. This study aims to analyze the difference between architect and urban planner's point of view in evaluating international design competition works which the internationally distinguished honorable design companies(SOM, Jerde Partnership, Studio Daniel Libeskind, Foster+Partners and Asymptote Architecture) submitted as the ideas of Yongsan International Business District Design. Furthermore, we made an attempt to quantify the weight of each factors of urban design by each group. Architect and urban planner's viewpoint were revealed with seven architects and seven urban planners evaluating the international design competition works through AHP(Analytical Hierarchy Process). AHP structure was made of two step hierarchy in terms of Master Plan and Landmark Tower. Eight evaluation criteria were set up such as the concept, land use, transportation, feasibility of Master Plan and the concept, location, functional efficiency and aesthetic beauty of Landmark Tower. Results show that Architect have different point of view from that of urban planner. While the architect's weight of evaluation criteria is on the Landmark Tower(0.505), urban planner's weight is on Master Plan(0.642). Feasibility, the location of Landmark Tower and land-use are very important evaluation criteria to architect and urban planner in common. Functional efficiency of Landmark Tower is in architect's favour and transportation is in urban planner.

Purpose: Hospitals for patients and their guardians can, from the concept of healing, be removed from just gaining profits, but suggest a future-oriented direction for the hospital. Accordingly, there have been studies related to the selection of hospitals, but most were related to preference and satisfaction, and only recently did research from the concept of tradeoffs of factors for selection began to grow rapidly. Methods: From this context, this study evaluates the level of importance for factors of selecting hospitals using the analytical hierarchy process, and identifies the correlation with users, gender, age group, and outpatient features in order to identify the difference of awareness among different groups for selecting hospitals. In the factors for selection 26 factors in six categories were set through studies of preceding research, and after surveying 144 people, the following results were attained. Results: 1) The overall analysis results were found in the order of medical level, medical service, and fame, and low for facilities, which is similar to the cases of preceding studies. 2) For user analysis, it was similar between patients and guardians, but there was a slight difference in awareness among nurses, who are also medical service providers. Nurses showed relatively high level of importance in direct factors such as medical technologies and medical services, while guardians of patients showed higher importance in indirect factors such as facility environments and convenience. 3) Women showed higher assessments of importance levels in environmental factors, while men in physical factors. 4) The older the age group, the lower level importance there was on medical level, while the importance on fame reduced the further the commute to the hospital was.

Technical documents in the construction field are changing from paper documents to electronic ones. As a result, the industry witnesses a trend of using portable electronic devices in searching or retrieving necessary information such as relevant regulations. Despite the improvement in the accessibility to general technical documents, a limitation is still found in accessing the electronic documents on the regulations. We see the barrier for field engineers to enhance their technical knowledge. One of major barriers is that videos, animations, and virtual reality information to enhance the visual understanding of technical content related to regulations are not linked. It is the interactive electronic technical manual (IETM) that can address such issues. The IETM is an electronic document system that enables real-time information acquisition while operating in the form of conversations with users by linking multimedia functions to document types such as specifications and guidelines. This study establishes a model of the IETM that can be operated in the planning stage of a construction project. The study also verifies its usability with a hypothetical case study. This study aims to improve the usability of the IETM in the construction project by analyzing the application effect of the IETM using the AHP technique.

The global pandemic and the development of virtual and augmented reality technologies have led a metaverse boom that enables a lot of interactions in virtual worlds, and is being utilized in various fields such as business, government, and education etc. Despite the growing interest in the metaverse, its scope and definition are still unclear and the concept is still evolving, making it challenging to establish its governance. Governmental entities are also investing intensively in public metaverses to make public value and promote social welfare, but they are underutilized due to lack of systematic governance. Therefore, in this study, we propose a public metaverse governance framework and identify the relative importance of the factors. Furthermore, since a public metaverse should be accessible to anyone who wants to use, we explore the factors of shadow work and examine the ways to minimize it. Based on the socio-technical system theory, we derived public metaverse governance factors from previous literature and topic modeling and then generate a framework with 23 factors through expert interviews. We then tested relative priority of the factors using the analytic hierarchical process (AHP) from the experts. As a result, the top five overall rankings are: 'roles and responsibilities', 'standardization/modularization', 'collaboration and communication', 'law and policies', and 'availability/accessibility'. The academic implications of this study are that it provides a comprehensive framework for public metaverse governance, and then the practical implications include suggesting prioritized considerations for metaverse operations in the public sector.
