  • The transit-oriented development (TOD) model can effectively help to solve urban problems and promote sustainable urban development. The United States and Japan are widely considered the earliest two countries to start TOD practices; however, the origins of TOD models in the two countries were different. The TOD practices in the two countries formed distinct characteristics, yet their differences have been underexplored. This study aims to grasp the characteristics of the TOD model in the two countries through a systematic comparative analysis of 10 typical cities in the United States and Japan that have adopted the TOD model. This paper compares the case cities' three key aspects of the TOD model: public transit system, spatial form, and land use, and summarizes the characteristics of TOD models in the two countries from a city-level perspective, to help deepen the global understanding of TOD.

  • Vertical growth is viewed as the solution to the problem of urban housing. The present study aims to be multifocal in approaching the phenomenon of apartment living in Lahore, Pakistan. The primary focus of the research was to evaluate the satisfaction with and favorability of vertical living among the dwellers; however, the research was extended to include the in-depth experiences of adolescents regarding privacy because it was observed that this age group was being neglected severely in the distribution of privacy in apartments, as well as in research. The data was first collected from 150 respondents through a survey, and then interviews of 10 adolescents were conducted to explore notion of privacy. The findings highlight that, despite being satisfied with the infrastructural aspects of the building, the residents do not prefer vertical living over horizontal housing. The adolescents in apartments also prefer horizontal housing over vertical living to avoid the feeling of crowdedness that is associated with vertical growth due to shared space and proximity. The utilization of spaces within apartments is associated with certain elements of development of the personality during this age. The findings of the present study can be helpful for sustainable vertical housing policy development and implementation.

  • The present research evaluates the public engagement approach in various project stages. Hong Kong had long been criticized as top-down and executive-led jurisdiction by overlooking the importance of cultural heritage and public concerns on public projects. It was suggested to the government to engage public and provide sufficient public consultation. Thereby, the government announced a series of revitalization and conversion measures in Policy Address in 2008. To carry out the measures, there were voices, because of diverse and sometimes conflicting interests, over the effect of revitalization project. On the other hand, studies reveal that there are benefits of revitalization and enhancement of public engagement approach. In pursuit of the subject, the present research aims at studying the Central Market as a case study pilot project. In October 2009, the Policy Address announced that the Central Market be revitalized. Tasked to implement the project, Urban Renewal Authority (URA) continued to adopt the people-oriented approach as the guiding principle in its core business and in heritage preservation and revitalization so as to create a sustainable development. Between government and the public, URA acts as a bridge for communication. As between URA and the public, URA conducted public consultation, set up an ad-hoc committee in January 2016 to be in charge of the project and will continuously inform the government and public with the updates and project progress. The main objectives of the present research are to assess the advantages and challenges in different stages of public engagement approach, to evaluate the engagement system, to give a comprehensive view for participation of stakeholders, and to find out effective strategies to enhance civil engagement. Research was achieved through interviews to key persons in the project, questionnaire that was distributed to community and experts in the field. Case Study of the Central Market was studied and investigated using different sources, such as newspapers, journals, etc, to evaluate the degree of public engagement in the project. Both detailed qualitative methodological approaches of interview, questionnaire, and case study, act as a synergy to demonstrate the research objectives and provide the comprehensive perceptions on the revitalization project. The results show that public participants in revitalized project have generated considerable value enhancements to social-cultural, environmental, political and economic aspect. This study provides valuable insights that the public participation can make positive contribution to sustainability in the city. The findings indicate that no any single system is flawless therefore seeking both public opinions and professional advices are also important as a comprehensive approach to achieve higher sustainability of the building.

  • The main objective of this article is to highlight the progress made in the development of new materials that have been gradually used by humans until today. Of course, this progress must be associated with other parameters in order to guarantee sustainable development. For this, today, it has become urgent to reduce the consumption of cement by resorting to its partial or total replacement by other similar materials in order to reduce CO2 emissions in our environment. This should certainly help to develop greener building materials. In this study, it was decided to proceed with the partial or total replacement of Portland cement type CEM II/B-L-42.5N by slate and lime that had not undergone any previous transformation. The results obtained revealed that the mortar whose substitution compared to the replacement of cement (100%) cement and sand (0/4) confers better kinetics than those of the series composed of(100%) cement and fraction rubble (0/1).

  • Polymers, particularly plastics, have been widely seen as an existential risk to the environment due to their contribution to pollution, carbon emissions and climate change. Many argue that it is possible to substantially ease the threat of plastics by engaging the public in reducing their use in day-to-day life and implementing efficient domestic waste management strategies. On the other hand, polymers and plastics in building and construction are considerably less problematic, if not attractive. In fact, the applications of polymers in construction have been continuously expanding. This is partly due to the developments made in this area being implemented within a sustainable development strategy. In this paper, the main applications of polymers in construction have been revisited and an overview of the research topics in each application has been briefly presented.

  • ODA is an effort and action of international community to keep human rights by eradicating poverty. UN declared MDGs (Millennium Development Goals) during 2001 and 2015. As a follow-up action, UN sets up SDGs (Sustainable Development Goals) during 2016 and 2030. SDGs expands the concept of ODA. SDGs includes cooperation development over the scope of ODA by mobilizing various financial resources from public sectors and private sectors. It will overcome the limitation of traditional ODA and be 'AID and beyond'. Catalytic aid is appropriate for the concept of SDGs. Cooperation development by catalytic aid focuses on building economic infrastructure and production facilities rather than humanitarian aid, which will establish a sustainable development basis for recipient countries. This study suggests to make a PPP business by linking KSP(Knowledge Sharing Program), to objectify criteria of priority recipient selection and aid allocation, to adapt grant and concessional loan complexly according to the business, to support realization of CSV(Creating Shared Value) by establishing SPC(Special Purpose Company) and to construct a PCSD(Policy Coherence for Sustainable Development) system to fulfill the fore-mentioned strategies.

  • After the COVID-19 pandemic, hand hygiene has become more important to prevent and reduce infection. To manage and provide water to ensure safe handwashing, water governance and the role of public servants are also getting critical. Many organizations have given their priority to capacity building of public servants. In the Strategic Plan for the ninth phase of the Intergovernmental Hydrological Programme (2022-2029), 'Water education in the Fourth Industrial Revolution' is included as a priority. In Korea, ODA in the field of water and sanitation is emphasized in Korea's 3rd Mid-term Strategy for Development Cooperation (2021-2025). Also, KOICA and various water-related organizations have been organizing water education programs for developing countries. This study presents the direction for water education for public servants in developing countries in the post COVID-19 through the education program cases of the International Centre for Water Security and Sustainable Management established by the agreement between the Korean government and UNESCO in 2017. The study suggests that water-related organizations should cooperate with each other to prevent duplication of water education contents. It also suggests that blended learning should be actively utilized for the improvement of education program effectiveness. Lastly, the study emphasizes that education demand for the water technologies related to the fourth industrial revolution and smart water management is increasing, which should be considered when water-related organizations create online content or design education programs.

  • Recently, the aging of public facilities in Korea have accelerated, and the existing framework for facility management is shifting toward to facility asset management in terms of performance-based proactive control. Therefore, the operation of public facility involves both safety assurance from the deteriorated facilities and management capabilities for sustainable maintenance in the required valuation and level of service, such as valuation of facility assets, life-cycle management plans, financing, and so on. In this study, the Facility Asset Management Indicator(FAMI) has been developed for public facility asset management, and it provides the quantitative management grade, based on international standards, such as ISO 55000 series and International Infrastructure Management Manual(IIMM). The FMMI includes 10 key areas to apply a diagnosis model into management capabilities, 113 detailed elements, and 5 maturity grades. As the importance of public facility asset management is increasing constantly, this is expected to identify previously the strengths and weaknesses of public facility operating institutions. Eventually, they can obtain the effective ways to improve their own capabilities, minimize the public funds, establish the strategies for innovating the current management structures, and operate stably the facilities in the required performance.
