Ecosystem service valuation is a crucial step for the sustainable management of watershed. In the context of various ecosystem services provided by watershed, this study, particularly deals with water yield computation in Bagmati Basin of Nepal. The water availability per population in Bagmati Basin is lowest compared to other basins in Nepal. Also, the rate of urbanization is rapidly growing over a decade. In this regard, the objectives of this study are 1) to compute the total water yield of the basin along with computation on a sub-watershed scale, and 2) Study the impacts of land use change on water yield based on CLUE-S model. For the study, Integrated Valuation of Environmental Services and Tradeoffs (InVEST), a popular model for ecosystem service assessment based on Budyko hydrological method is used to compute water yield. As well, CLUE-S model is used to study land use change, which is further related to study variation on water yield. The sub-watershed wise outcome of the study is expected to provide the guidelines for the effective and economic management of a watershed on a regional scale.

This paper introduces the result of performing research analysis on awareness and demand on economic aspect of dwellers toward remodeling by aiming at the fact that there are existing dwellers which is the biggest feature of remodeling. Providing services that are suitable for economic conditions and demands of owners or dwellers of Apartment House could be seen as something that must be considered first above all things in remodeling in which consumers have to pay for expenses are specified.

This study aims to estimate and calculate the ability to pay (ATP) and the willingness to pay (WTP) of households for wastewater management services (IPAL), the relationship between ATP and WTP, and factors that affect WTP. The location of IPAL construction is in the area of Lampung Province, Indonesia. There are 158 selected households for this study. The study employs a purposive sampling method in which the characteristics of households are classified into 3 categories - former households, newcomer households who had come to this area and have no experience of using water supply services, and newcomer households who have experience of using water supply services such as PDAM. The results of this study are, ATP and WTP values were not always in the same direction. The highest ATP was for newcomer households with experience of water supply services but the WTP was the lowest, on the contrary, the lowest ATP was for former households, but the WTP was the highest. Furthermore, experience and cognitive reference are positively correlated with WTP. Service quality perception, education/knowledge of respondents about environmental conservation, and level of income correlate with WTP.

Give high priority to the technologies that can be directly applicable to the U-City development projects which are in progress by many central and local governments. Create a real world product at the end of R&D phase by testing prototypes in test-beds or test-labs. Recently, new construction technologies have been developed, but they are rarely being applied to the construction filed. In this paper, the basic design was examined so that various technologies can be selected through a test-bed, analyzed for the real situation, and applied to actual construction sites. Improve productivity of regional and urban construction exercises and improve competitiveness of related products and services using IT-based telemetering/GIS technology.

For the development and management of u-City(ubiquitous city), Ubiquitous City Construction Law was enacted(March 3, 2008) to form the legal basis of u-City plan, construction and managements afterwards. The ultimate goal of the u-City construction is the advancement of national territory utilization and management using Korea's high level of IT and spatial information infrastructure. Based on the definition of the u-City Construction Law, the u-City refers to a city where u-City services are provided through the u-City infrastructure applying u-City technology. But, based on the current level of relationship model among u-City service, technology and infrastructure, it is not enough to guide the local municipalities to plan and provide the successful u-City services in its vicinity. So as one of the core issues for the legal arrangements of successful u-City services, the purpose of the study is to suggest the basic directions and execution strategies for the relationship establishment among u-City service, technology and infrastructure.

Project cost is an important concern in any construction project. Although there has been a lot of studies on factors affecting the cost of construction projects, there seems no consensus as what cost factors have direct influence on the cost of civil engineering projects. This study therefore aims to bridge the current knowledge gap by examining quantity surveyors' perception of the factor structure among nineteen costing attributes identified based on literature review. Questionnaire was used to elicit responses from quantity surveyors working in the Hong Kong construction industry. Principal component analysis is conducted to extract the factor structure of the cost attributes and the attributes are grouped into three factor components, namely the contract management factor, the project management factor and the monetary value factor. Understanding these cost impact factors could be crucial in managing civil engineering projects, since it allows the project stakeholders and quantity surveyors to take precautionary steps to identify the cost management problems and areas for improvement and could even help to avoid cost deviations in engineering projects.

2005, National railway was converted from government enterprise form to public corporation form. Korail is facing in necessity to equip new manpower operating system to achieve public enterprise's part and two purposes called profit creation according to conversion to construction system. Accordingly, railway construction work began services for formation diagnostic and job analysis to construct management formation of new paradigm, personnel management course manpower operation system of the job value priority. This dissertation is research for direction establishment of human resource management(HRM) of railway construction work. Examined problem of current personnel management system with trend of HRM paradigm for this. And presented various strategy to construct greeting executive system of job putting first in person putting first and strengthens formation capacity.

Cloud BIM, which incorporates cloud computing technology and BIM technology, is increasingly used in construction. In particular, the recent trend of cloud services in IT field is to provide customized cloud services according to the characteristics of users. These changes are also linked to the cloud BIM, which is emerging in the construction industry. However, cloud BIM researches and commercial technologies that are currently underway do not reflect these trends, and they provide services through generalized management functions in construction projects. In order to solve these problems, a new type of customized cloud BIM service is needed that can provide cloud services by reflecting the characteristics of the project, customization based on the user's work, and providing the knowledge service. Therefore, this study aims to derive the system requirement function that should be preceded for implementing the customized cloud BIM service, and the target project is selected as the medical facility.

A robust asset management methodology is essential for effective decision-making of maintenance, repair and rehabilitation of a bridge network. It can be achieved by a computer-based bridge management system (BMS). Successful BMS development requires a reliable bridge deterioration model, which is the most crucial component in a BMS, and an optimal management philosophy. The maintenance optimization methodology proposed in this paper is developed for a small bridge network with limited structural condition rating records. . The methodology is organized in three major components: (1) bridge health index (BHI); (2) maintenance and budget optimization; and (3) reliable Artificial Intelligence (AI) based bridge deterioration model. The outcomes of the paper will help to identify BMS implementation problems and to provide appropriate solutions for managing small bridge networks.
