In general, the process of building construction makes the inevitable wastes such as nails, formwork, steel and concrete. In order to reduce these wastes, parts of building have therefore been produced by using the manufacturing process. This process can improve construction process with minimum wastes and time of construction. However, the manufacturing process is not completely effective for building construction. There is also an additional cost for the transportation from manufactory to the construction site. For this reason, to set the exact time of the construction process, to avoid material waste and to effectively reduce the construction cost, all the production processes of manufacturing building should be started and ended at construction sites. This research has studied the Lean Manufacturing Process (LMP) and applied to the process of the construction which is called "the building with the on-site manufacturing process, BMP" to reduce instable human resource by machines which provides three advantages as follows: 1) the better quality, 2) minimum constructing cost and 3) minimum constructing period. © 2018 International Association of Lowland Technology.

This paper presents the application of the Analytic Hierarchy Process (AHP) in rural roads prioritization. The paper exhibits the concept and process of the plan for rural road development and application of multiple criteria decision analysis using AHP for prioritizing rural roads on a rational basis. Rural road network was grouped on strategic issues and strategies of Department of Rural Roads. There are three main factors to be used as an indicator to assess the importance of routes of each type of road: Transport and Traffic engineering, Accessibility and Other. The result of criteria weights was determined by Expert Choice software according to the AHP model. The results of weight factor analysis can be divided into 2 groups: The Transportation and Traffic engineering dominant road (Logistics, Traffic Reduction and Country's Border Road) and the Accessibility dominant road (Tourism and Rural Area Accessibility Road). This study will be able to prioritize rural roads and allocate limited budget for development in the future. The master plan obtained from AHP application shows that this plan is consistent, and links with the country strategic plan under the Department of Rural Roads year 2017-2026, which is a longterm plan (10 years), and the Strategic Plan Framework Development of Rural Roads year 2017 - 2020, which is a medium-term plan (4 years). The main goal of the Rural Roads Development Plan in the area is to develop a rural road network to connect the Development of National infrastructure and the Northeast Development Plan perfectly. © 2018 International Association of Lowland Technology.

Maintenance of the stadium has been done for the 18th Asian Games 2018. However, the previous maintenances were not comprehensive and held in the run up to the big events only. It affects the performance of its components utilities. A new local company was established by the Government of South Sumatra Province, in order to make a good maintenance of the stadium. However, the planned maintenance has not been actualized by the company yet. Many obstacles encountered in stadium maintenance, including regulatory, complexity of utilities, and stakeholder's influences. This paper aims to develop a maintenance system that is in accordance with existing conditions and applicable regulations. This study is devoted to electrical lighting systems because almost every week the stadium is also used for football matches. The methodology was divided into three parts, i.e.: rating for each parts of the utility, descriptive qualitative for regulatory identification, and stakeholders analysis, and they are developed to create a maintenance system. The result is a system that is proposed to find out the most important stakeholders in the maintenance of the highest priority of lighting utility based on official assessment.

Lowland Technology International 2018年第1期20卷 65-76页

作者： Kulariyasup, W. Horpibulsuk, J. Horpibulsuk, S. Graduate Program in Construction and Infrastructure Management Suranaree University of Technology Nakhon Ratchasiam30000 Thailand Institute of Medicine Suranaree University of Technology Nakhon Ratchasiam30000 Thailand School of Civil Engineering Institute of Engineering Suranaree University of Technology Nakhon Ratchasiam30000 Thailand

This paper presents the design of the new Thammapakon Pho Klang Nursing Home, Nakhon Ratchasima, as a modern model for Thai nursing homes. The nursing home is based on green-building, energy-saving and human-factors engineering principles and covers an area of 102,000 m2 (2,520 acres). The model includes the site design and the buildings of the nursing home, which conforms with green-building and energy-saving principles. The novel nursing home represents a practical approach to the optimization of building use and building resources in the areas of building utilization, water management, waste management, environmentally friendly materials selection, the effect of buildings on the health of building users and the environment, construction, operations, maintenance, and final demolition. The designed buildings include an office building, a hospital, a dormitory for the elderly, a canteen and a multipurpose building. The elderly’s facility design is based on universal design and human-factors engineering. Google’s SketchUp 8 program was used to design the layout of the buildings, the style and size of the openings around the buildings, the building envelope materials, and the position and types of vegetation around the building according to sun direction. It was determined that the overall thermal transmission values (OTTV) and the roof thermal transmission values (RTTV) of the designed buildings are within the prescribed energy-efficient building standard (OTTV 2 and RTTV 2). © 2018 International Association of Lowland Technology.

Freshwater scarcity and unsustainable water use is a growing concern in many developing countries including India. Increasing water demand coupled with rainfall variability associated with climate change exacerbates water scarcity. The increase in water demand is attributed to population and economic growth as well as technological change, and the gap between the actual water available and the demand continues to widen. This study aims to develop a large-scale assessment model of sustainable water use in India during the period 1970 – 2010 at a spatial resolution of 50 km x 50 km and a temporal resolution of monthly timescale. A Community Land Model CLM 4.0, developed by the National Centre for Atmospheric Research (NCAR) of the US, and census-based statistical database are used in this study to quantify and assess the sustainable water use in India. We define the measure of sustainable water use as the difference between the total water available and the total water demand. For each grid cell, the total water available is modelled as the sum of surface runoff and groundwater. The total water demand is estimated as the sum of irrigation, industrial, domestic and environmental water demand in each grid cell. Among the demands, the irrigation water demand is modelled based on census data sets of irrigated areas and irrigation water withdrawal while the domestic and industrial water demand is modelled as a function of population, economic and technological indicators such as gross domestic product, electricity, fuel consumption and industrial outputs. However, the environmental water demand is modelled as a function of total water available, following hydrology based approach, with seasonal variation of water demand to meet the various ecosystem services considered. Based on preliminary analysis, the rate of increase in industrial water demand (~2% increase per annum) and domestic water demand (~1.2% increase per annum) is higher than the rate of increase in irrigation

Summary Being the second-largest country in the Middle East, Iran has a long history of civilisation during which several dynasties have been overthrown and established and health-related structures have been reorganised. Iran has had the replacement of traditional practices with modern medical treatments, emergence of multiple pioneer scientists and physicians with great contributions to the advancement of science, environmental and ecological changes in addition to large-scale natural disasters, epidemics of multiple communicable diseases, and the shift towards non-communicable diseases in recent decades. Given the lessons learnt from political instabilities in the past centuries and the approaches undertaken to overcome health challenges at the time, Iran has emerged as it is today. Iran is now a country with a population exceeding 80 million, mainly inhabiting urban regions, and has an increasing burden of non-communicable diseases, including cardiovascular diseases, hypertension, diabetes, malignancies, mental disorders, substance abuse, and road injuries.

Department of Civil Engineering Faculty of Engineering and Architecture Rajamangala University of Technology Isan Thailand Construction and Infrastructure Management Program Suranaree University of Technology Nakhon Ratchasima30000 Thailand School of Civil Engineering Suranaree University of Technology Nakhon Ratchasima30000 Thailand School of Engineering and Resources Walailak University Nakhon Si Thammarat80160 Thailand Swinburne University of Technology HawthornVIC3122 Australia Institute of Geotechnical Engineering Southeast University Nanjing Jiangsu210096 China

Sludge-fly ash geopolymer is a green material, which does not require cement as a cementitious binder. Sludge and fly ash (FA) are both by-products from Bang Khen water treatment plants and Mae Moh power plants, respectively. A liquid alkaline activator, L is a mixture of sodium silicate solution (Na2SiO3) and sodium hydroxide solution (NaOH). This article investigates the influence of compression energy (E) on the Unconfined Compressive Strength (UCS) of a novel sludge-fly ash geopolymer. The optimal liquid alkaline activator (L) content, sodium silicate solution to sodium hydroxide solution ratio (Na2SiO3/NaOH), heat temperature (T) and heat duration (D), providing the maximum UCS for each E is also investigated. Test results indicate that the optimal UFA ratio decreases as E increases. The optimal L/FA ratios for E = 592.5, 1346.6 and 2693.3 kJ/m3 are 1.5, 1.4 and 1.3, respectively. The Na2SiO3/NaOH ratio of 80:20 is considered as optimal for all E tested. The UCS of sludge-FA geopolymer at all E values tested increases with an increase of heat duration until a heat duration of 72 hours, after which the UCS becomes almost constant. The heat temperature accelerates the geopolymerization reaction and therefore enhances the strength. However, overheating results in micro-cracks in the samples due to the loss of moisture. As such, the optimal temperature is controlled by liquid content;the higher L/FA results in the lower optimal heat temperature. Since the optimal L/FA ratio decreases as E increases, the optimal T subsequently decreases with an increase in E;i.e., its values are 75, 85 and 95 °C for E = 2693.3, 1346.6 and 592.5 kJ/m3, respectively. The maximum UCS values of sludge-FA geopolymer at optimal ingredient and heat condition are 20, 18 and 16 MPa for E = 2693.3, 1346.6 and 592.5 kJ/m3, respectively, which meet the strength requirement of bearing masonry units as specified by the Thailand Industrial Standard (TIS).
