  • This paper describes a new quantitative process for evaluating the roughness of discontinuity, which is suggested as a qualitative criteria in RMR or Q-system. For this purpose, the Delphi method which is one of the surveying methods was introduced. The selected panels were asked to evaluate the roughness of discontinuities on the Web which was hosted by authors in advance. A total of 3 surveys were performed using JRCs suggested by Barton and Choubey as well as Ai generated by the Monte Carlo simulations. After each survey, the results were provided to all panels for comparing their decisions to others. As surveys proceeded, better consensus and convergence were achieved. With a good agreement of panels on roughness classification, the quantitative criteria for roughness of discontinuity in RMR and Q-system was established in this study.

  • The purpose of this study is to identify the design features appropriate for the altered physical characteristics of pregnant women and formulate the direction of future design and development of maternity wear. A Delphi research method based on a panel of experts and pregnant women was used and the survey was conducted to determine the suitability of maternity wear. The survey found that A-line silhouette outerwear with round necklines, with wide sleeves and snap-button fastening on the front with a formal and decent look was considered appropriate as maternity and postpartum wear. Shirts and blouses long enough to cover the hip area to complement women's curvy and full figures, especially around the bust, waist, and hip areas during the later stages of pregnancy were found to be appropriate. Calf-length pleated skirts were comfortable to wear during pregnancy due to the abundant freedom of movement and space offered by pleats. Ankle-length straight leg pants were rated appropriate in terms of comfort and style both during late stages of pregnancy and at work postpartum. Dresses decorated with pleats from the armholes all the way down to the knees were found to provide high levels of comfort at the abdomen, chest, and hips, and considered appropriate. Based on this study results, a follow-up study will be conducted to examine the design of maternity wear during pregnancy as well as at work after pregnancy.

  • As the government has enforced recently the policies on the distribution of the housing, the construction cost of multi-family housing projects has increasingly become very sensitive and political issue. However, it is difficult to predict the construction cost in planning and design phase of the project because the Bill of Quantity of the multi-family housing projects was composed of breakdown structure based on each work package. To predict the construction cost in planning and design phase for multi-family housing projects in more effective and reasonable way, this study developed the cost breakdown structure based on spaces using Delphi method. The Cost Breakdown Structure (CBS) based on spaces for multi-family housing projects basically consists of three parts: (i) Building part; (ii) Non-building part; and (iii) Additional part. The characteristics of spaces in multi-family housing projects are fully taken into consideration. Then these three parts were subdivided into work packages in terms of work tasks. Additionally, the usefulness and effectiveness of Space CBS in this paper were validated by analyzing the BOQs of several collected sample projects and matching with Space CBS afterwards.

  • When developing projects to build facilities to be shared by both military bases and surrounding communities, strategies are needed to achieve two objectives: 1) minimize missteps and opposition from local communities in the process of developing and implementing such projects, and 2) promote cost-benefit optimization and user-satisfaction. With aim of promoting co-operation and co-existence between military bases and adjust communities, this research proposes esthetical factors to be considered in conceiving civil-military sharing facilities. It seeks experts' opinions on the development of civil-military sharing facilities, and examines critical factors (economic feasibility, security, and satisfaction, etc.) for project development as well as building types suitable for shared-use between military bases and local residents. It then establishes a method to prioritize facility-type and narrow down design factors (considerations and restrictions) in project development by applying quantitative analysis. The methodological approach of the research employs the Delphi survey method to quantitatively analyze qualitative information drawn from experts' opinions. At the first round of the survey, facility types, items for consideration and restrictions are drawn, and then at the second round of the survey, criticality of each item is analyzed. Finally, it reaches a conclusion on suitability of facility types for civil-military sharing facilities, and selects project considerations and restrictions when developing this kind of project.

  • The digital transformation of the shipbuilding, shipping, and logistics sectors is predicted to lead to the introduction of autonomous ships and changes in the way ships are operated. The co-existence of various operation forms, such as autonomous operation and remote operation, with the existing operation methods is expected to lead to the transformation of the ship operation process and the emergence of new stakeholders. This paper studies the future ship operation process according to the change in ship operation method, predicts the change in the operating environment of future ships, and derives functional requirements by major tasks and stakeholders. The Delphi technique is applied to construct a ship operation scenario from the planning stage of voyage and cargo transport to the stage of arrival at the final destination port and discharge of cargo, and to predict future work changes by task and actor. Seafarers' activities are expected to be minimised by remote and autonomous operation, and experts in each field are expected to have responsibilities and tasks in different aspects of ship operation.

  • This study aimed to construct the Library Map Information System(LMIS) based on the Wiki theory of Web 2.0. We built this system because there was no collective source of information about every library in the world. Also, this system was developed to provide a library location information service by mashing-up with the Google Map. Through this study, the metadata applied to the newly constructed system was developed by using the Delphi method. A total of 13 experts including librarians of schools, public, academic, special, and national libraries as well as LIS faculty members and researchers, were commissioned as Delphi experts. Through three rounds of a Delphi survey analysis, the addition, modification, and deletion of the initial metadata elements was accomplished, and then the library contact/location information, library information, collection information, and event information was proposed. The metadata for LMIS was organized into four sectors and then 49 elements, each assigned to a sector.

  • The goal of the education of Information Communication Ethics(ICE) is to improve the consciousness of young people so that they themselves are able to judge between what's ethically right and wrong and, as a result, to take the right behavior. For this, we need to preferentially identify the primary factors in understanding and diagnosing the consciousness level of young people on the ICE. To solve this problem, in this study, we identified four major indices that consist of the ICE consciousness through the meta analysis of the both domestic and international researches from the past 5 years in the related area and then, they are validated by experts. We also analyzed the factors in assessing the ICE consciousness of young people by using the Delphi technique, which, during its analysis, even considers elements that are qualitative or cannot be objectified, through the help of an expert group that consists of experienced teachers and professors in the related area. As a result we deduced 4 major indices and 45 related factors.
