Bromilow's time-cost (BTC) relationship was examined for building projects in Vietnam using actual construction time and total construction cost. Data set was collected from 77 historical building construction projects completed between 1999 and 2005 which were adjusted by consumer price index (CPI) to 2000 price. Time-cost equations were specified respected to two sectors, public and private, in Vietnamese construction industry and all cases. It is shown that a public funded building project has the longer construction duration than a similar budget private funded project. The resulting models are statistically significant. The adjusted R-square coefficients of all cases, public and private projects models are respectively 0.403, 0.436 and 0.377 mean that the BTC regression lines moderately fit the data set.

This thesis aims to show the design logics and the meta-design of a public restroom "Between You and Me." This work reinterprets a public restroom regarded as the typical public space by means of spatial agency's influences, on the assumption thor spatial agency controls the properties of public space. This thesis examines our representational system against the public space, and our specific experience in it with the conceptual model of meta-design. Meta-design is a design beyond the design usually we think of. Experiential meta-design, "Between You and Me" presented as the object of this thesis, is a constructive design project which converts our negative perception of the restroom to a new one, "interface." This project, composed of the surrealistic spatial arrangement, urges us to reconsider our fixed thoughts of the restroom and try a creative experience in it. Finally this thesis shows how the space's way of existence fixes our acts and thoughts, and what enables the repetitive acts and thoughts often emerged In our relations with the public space through a meta-design.c space through a meta-design.

The paper investigates X-project, in which the public was invited to participate in a national R&D project, examines how X-project attracted the public's attention and involved them in a national R&D project, and discusses the significance and limitations of X-project. X-project was executed by a 12 citizen-led committee, financially supported by the Ministry of Science, ICT, and Future Planning, and backed by the Science and Technology Policy Institute. People raised 6,212 questions that reflected the severe needs they experienced in their daily lives through the online and offline platforms of X-project. In addition, the committee members, scholars, experts, government officials, and citizens gathered together to select the fifty most provocative and novel of the questions raised by the public, and invited public participation to answer the questions in innovative ways. 310 research teams including professional researchers from universities and institutes, high-school students, lay persons, and corporate workers applied for X-project, and 54 of these teams were finally selected to receive funding from the government. Through planning and conducting X-project, as well as interviewing and surveying the participants in X-project and non-participants, we found that there was an enormous social consensus on the necessity of public participatory national R&D projects. People asserted that science and technology should put a greater focus on solving social problems and satisfying public needs. We also confirmed that the public could take part in national R&D projects. Most of all, we found that the questions raised by the public were very challenging, novel, and complex, and thus researchers need break-through approaches to address them. It can be also argued that through experiencing the X-project citizens can regard themselves as ones who are not only recipients of the benefits of the development of science and technology, but also contributors of the development of them. We finally argue that there are some limitations to X-project in terms of how to provide diverse incentives that attract more participation, how to develop the process in which people got involved in the project in more easy ways, and how to create new ways for lay persons and professional researchers to cooperate in solving social problems.

Successfully adapting to digital and customer-oriented transformation, the concept of lean manufacturing professes the philosophy of creating greater benefit while minimizing losses. These losses are operations that do not add value in the production process to ensure the efficiency, flexibility, and profitability of projects. In the context of broad automation and digitalization of all sectors of the economy, mechanisms for combining automation technologies and lean production are becoming available. Moreover, when it comes to the efficient use of financial, human, or material resources, it is clear that the use of Industry 4.0 technologies can be an effective tool for achieving the goals of lean production, as many of them pursue the same goal. In this context, this article aims to study the effectiveness of the implementation of project management concepts at the global level and identify the main factors influencing its effectiveness to ensure the achievement of lean production through LEAN technologies and Industry 4.0 technologies. To achieve this goal, several statistical indicators were selected and several statistical methods of analysis were used: pairwise correlation, regression analysis, methods of comparison, synthesis, and generalization. Statistical analysis was conducted according to a survey conducted by the Project Management Institute (PMI) in 2020. An economic-mathematical model of dependence of project effectiveness in different regions of the world on the level of implementation of project management approaches is built, which shows that the increase in project effectiveness by 85% is due to financial losses, technical training, and consumer orientation. These results allow project managers to develop appropriate strategies to improve project management approaches at all levels. It is established that LEAN technologies and technologies of Industry 4.0 have several tools that have a positive effect on minimizing losses following the concept of lean production. Besides, given that the technology of Industry 4.0 is focused on the automation of Lean Production technology, a mechanism for the introduction of lean production using these technologies and methods.

This study evaluated how folly is experimented in the contemporary architecture after 30 years when Bernard Tchumi first introduced it to the public by the modern transformation as a garden ornament. First, folly project has been carried out based on the general concept of energizing dwindling cities. However, it has changed to the direction of adding specific programs. Also, along urban regeneration that does not change deterioration of previous structures, Folly changed in the emphasis on readjust existing structure. Second, by having different designers presenting their own follies during the Osaka Expo, folly now has part on visual exhibition element. This has similarity with public art project, yet it could more actively intervene for urban regeneration compared to conventional environment sculpture. Third, folly is experimented as the event-installation art combined form of architecture and art where people could experience the space and enjoy art. Fourth, folly enabled the landscaping of architecture and expanding city planning. Recently Gwangju Folly invited various arts, social, and cultural professionals to converge city design with architecture, landscaping, and other diverse genres.

This thesis analyzed the uniqueness of a toilet plane structure, centering on a case of Beautiful Public Toilet Construction Project under a project by Chungcheongnam-do and drew a conclusion as followings. Most of public toilets, constructed under a project by Chungcheongnam-do, were located in remains, tourist resorts, parks, and the outskirts of traditional markets. They were constructed at the selected location within an easy access of most user and plane structure was also designed so that the persons, in charge of management and maintenance, and the users could use them without difficulty. But some public toilets didn't establish the handicaps' toilet or made them difficult to sue due to location or size. The plane structure style was various such as a rectangular, stream line, or circle in accordance with location or building size. A circle-styled toilet offered a good view but didn't offer a good access or an effective space for users. In addition, when a handicapped person enters a toilet, he or she has to enter or go out of it through a sliding dor. So a constructor has to make progress of a work in accordance with this point.

Building Information Modeling (BIM) is utilizing CAD technology in a way that ultimately ties all the components of a building together as objects imbedded with information, and has been changing the way we design and build over the last 20-30 years. In Polytechnic Institute of NYU, there are four BIM courses offered which provide students with different levels of knowledge regarding BIM Technique, BIM Standards, BIM Guideline and Roadmap for Private and Public Implementation, BIM Application in Real Projects, the Cooperation of BIM and IPD for Public Works in New York City. With advanced BIM technology, BIM's integration into the construction process and its incorporation into project delivery systems, especially Integrated Project Delivery (IPD) are the bridges between technology, industry and research. This paper presents an integrated BIM curriculum with three modules: 1) BIM functions and Bid Preparation; 2) Time-Cost Trade-off Analysis; and 3) Problems Solving in BIM/IPD Environment. In this project-based curriculum developed by the common efforts of academia, public agency and industry, the objectives are: (1) to provide the information and skills needed to successfully implement BIM into the construction phase; (2) to identify BIM's role in construction and the project delivery system; (3) to develop a module in conjunction with leading BIM into project delivery system, particularly coordination between BIM and IPD; (4) to connect technology and research into industry. The course assessment was conducted and the results indicate that it is a successful reform in construction management education.

Public-Private-Partnership(PPP) is becoming a popular form of projects in construction industry worldwide. Normally, the management team of PPP project consists of various experts from different disciplines such as construction engineer, bank financier, contract manager, investors, etc. The diversity of team members causes difficulties in managing the team efficiently and furthermore for the smooth execution of the project itself. One of the solutions to this issue might be the application of citizenship behavior by the team members. This study conducts an empirical investigation of the effect of project citizenship behavior on the project performance. We have collected data by using a questionnaire from those with PPP project experiences in the domestic construction industry. The results show that project citizenship behavior has full mediating effects between PM's leadership and the project performance. This study has an academic significance in that it is the first attempt to apply the concept and to show the effect of citizenship behavior in project management discipline, particularly in construction industry, in Korea. We also expect that the project management teams for PPP projects would benefit from the findings of this study.

Promulgation of the Environment Preservation Act of 1977 has tried to conserve the environment encroached by the development projects. Since 1983, this act has included tourism development in EIA project and public participation as a part of EIA process since 1991. Still, there are many problems in applying the gathered opinions of local residents in such development plans. Therefore, it is necessary to develop a new system in whole project process as well as EIA to reflect these opinions. This study aims to investigate the problems in the process of the public participation and to suggest more effective solutions from the developer's point of view. Studies include theories of public participation developed in the planning process and the opinion survey of developers.
