Freshwater problems in coastal areas include the process of salt intrusion which occurs due to decreasing groundwater levels below sea level which can cause an increase in salt levels in groundwater so that the water cannot be used for water purposes, human consumption and agricultural needs. The main objective of this research is to implementation of RWH to fulfill clean water needs in tropical coastal area in Tanah Merah Village, Indragiri Hilir Regency, with the aim of providing clean water to coastal communities. The approach method used based on fuzzy logic (FL). The model input data includes the effective area of the house’s roof, annual rainfall, roof runoff coefficient, and water consumption based on the number of families. The BWS III Sumatera provided the rainfall data for this research, which was collected from the Keritang rainfall monitoring station during 2015 and 2021. The research findings show that FL based on household scale RWH technology is used to supply clean water in tropical coastal areas that the largest rainwater contribution for the 144 m² house type for the number of residents in a house of four people with a tank capacity of 29 m² is 99.45%.

This study aims to analyse the current state of library and information science (LIS) education in South Korea and identify educational challenges in building a sustainable library infrastructure in the digital age. As libraries’ role expands in a rapidly changing information environment, LIS education must evolve. Using topic modelling techniques, this study analysed course descriptions from 37 universities and identified 10 key topics. The analysis revealed that, while the current curricula cover both traditional library science and digital technology topics, focus on the latest technology trends and practical, hands-on education is lacking. Based on these findings, this study suggests strengthening digital technology education by incorporating project-based learning; integrating emerging technologies, such as data science and artificial intelligence; and emphasising community engagement and soft skills development. This study provides insights into improving LIS education to better align with the digital era’s evolving demands.

While infrastructure provides necessary public services and is vital for the socio-economic development of a nation, public funds alone cannot finance all infrastructure needs in society, especially after the COVID-19 pandemic, where many countries are facing budget deficits. Although private financing schemes, such as public-private partnerships (PPPs) and land value capture, have been considered intensively, they have yet to produce adequate private capital flows to infrastructure projects due to a lack of incentives for private investors. Against the background, this paper proposes a new financing mechanism in which governments might divert some of the increased tax revenue from the spillover effects of newly constructed infrastructures to fund the private sector through grants or subsidies. The empirical work in Vietnam shows a significant increase in tax revenues after completing two expressways, supporting our idea about spillover effects, which includes small- and medium-sized enterprise (SME) development. This study’s results suggest that spillover effects can bring new opportunities for governments and multilateral development banks (MDBs) to implement infrastructure projects with greater private sector involvement in the region. It also proposes some financial schemes, such as land capture and financing for business startups, including SMEs, to enhance the spillover effects of infrastructure.

The recent coronavirus-19 pandemic has highlighted the need for a global digitally enabled healthcare advancement infrastructure to ease e-coverage in the future and reduce human losses, facilitating access to high-quality and cost-effective health solutions. As the concept of a virtual healthcare system is still premature, it would have required noteworthy speculation in technologies and an overhaul of most of the current classical healthcare infrastructure, policies, and systems around the globe. Aims and objectives: This study aims to create a viable autonomous virtual universal health care system to modify the comfort of health care through emerging digital and communication innovations to fulfil consumer needs. Methodology: This study falls under the fact-finding category, which encompasses an exploratory approach with literature examination, limited field visits with informal interviews with local key authorities, and an initial assessment of current circumstances to examine the possibility of application of virtual health coverage. Findings: This study discovered that it is imperative to organize and develop the prospected healthcare system at the country level to be governed by international organizations as speculatively it is functioning in comparative improved healthcare systems across the world, which should be based on special processing of the prospected six types of data with their operationalization to serve multidisciplinary bunches by e-governance and exchanges between distinctive measurements. It requires more dependence on digital infrastructure and learning materials through electronic resources and ordinary techniques. Among other effective components for the development of virtual health coverage, are the applications of digital technology, the middle utility of voice and brief advising framework, complex functionalities, and applications of fifth generations (5Gs) arranged into universal servers attached to GPS-appropriate for sound choice and high-quality measures. Recommendations: This study recommends the construction of a virtual healthcare system by utilizing the proposed Electronic domestic medical adviser, virtual clinics, or “e-health incubators” which will allow individuals to relate through the web rather than the face-to-face institutive fragmented structure systems.
