Published: March 2020

Abstract
The information about teachers’ scaffolding in teaching and learning mathematics, especially in Indonesia, is still limited. This study aims to investigate mathematics teachers’ scaffolding in a teacher certification programme (Pendidikan Profesi Guru hereafter PPG) in Banda Aceh. This study involved two in-service teachers participating a professional experience placement program in one of Junior High Schools in Banda Aceh. The video recordings of participants’ teaching practices were analyzed qualitatively to examine the balance of teachers’ scaffolding and students’ responses based on five scaffolding strategies. The results show that both teachers used the pseudo-contingent type of scaffolding, in which the teachers were still not able to appropriately facilitate students to learn the given topic. T1 conducted four scaffolding strategies, namely: offering explanation, inviting student participation, verifying and clarifying student understanding, and inviting students to contribute clues. T2 provided five scaffolding strategies, namely: offering explanation, inviting student participation, verifying and clarifying student understanding, modelling the desired behaviour and inviting students to contribute clues. Therefore, the PPG likely needs to implement a specific strategy to improve teachers’ ability to provide effective scaffolding for students’ learning, for example, by providing extra time for in-service teachers to practice implementing the appropriate scaffolding during peer-teaching activities.
GIS for planning a sustainable and inclusive community: multi-criteria suitability analysis for siting low-income housing in a sustainable community and suitable neighborhood in Buffalo Metropolitan Area, New York
Authors: Saleh I , Setyowati N D A 
Published: March 2020

Abstract
This study utilized Geographic Information System (GIS) as a tool for sustainable community planning which incorporateslow-income communities into current sustainable neighborhoods. GIS suitability analysis aimed at finding suitable and sustainable neighborhoods for locating subsidized housing projects for low-income families through the Low-Income Housing Tax Credit (LIHTC) program in the Buffalo Metropolitan Area (BMA), New York. LIHTC projects allocate 30% of their rental units for low-income families. They must be located in sustainable neighborhoods to ensure economically and socially sustainable livesfor low-income inhabitants. Data was collected from various New York State government agencies and used as input for several raster-based criteria maps using GIS network analysis, raster cost-distance analysis, Kernel density analysis, raster-based local statistics, and surface analysis.The criteria of sustainable neighborhoodsusing GIS multi-criteria analysis (MCA) were grouped into five factors, namely public amenities, economic viability, population growth, property conditions, and environmental factors. A final suitability map was created by multiplying the derived raster maps with their respective weight resulting from the Analytical Hierarchical Process (AHP). The study found several locations in suburban areas of the BMA that meet the criteria and canbe usedby the Buffalo Metropolitan Housing Authority (BMHA) to site the LIHTC housing.

Published: March 2020

Abstract
School buildings are important for the education process. Surabaya, the second-largest city in Indonesia has many public-school buildings. As the buildings have a long project life cycle, the concept of sustainable development is relevant for this type of facility with regard to promote maximum benefit to the community. This paper aims to determine the criteria of social sustainability for the public-school buildings in Surabaya. The study first identified the variables based on literature. Then, a preliminary survey involving four experts was conducted to verify which variables should be used for the questionnaire survey. The variables were also analyzed using mean and standard deviation (SD). The study found 17 relevant indicators for measuring the social sustainability of school buildings in Surabaya. The five most relevant indicators are (1) the building is supported by users and the community; (2) the building is close to public transportation facilities; (3) the building can fulfill the needs of the local community; (4) the building can adapt to changes; and (5) the building is accessiblefor all people. The implementation of social aspects in construction projects is expected to deliver not only short-term, but also long-term project benefits to the community, as this aspect is closely related to community interests.

Published: March 2020

Abstract
The increment of the ageing population across the globe shows a rapid social change of the generations. The phenomenon that was utterly debated in the past four decades surrounding developed Western countries are now expanding the horizon of concern to developing countries too. However, an extensive review of literature identified that there exists a lack of appeal towards the elderly in heritage tourism of developing countries though they have sufficient disposable income and greater commitment compared to the past. Hence, the objectives of this review paper are to identify the elderly’s characteristic and underpin the importance of heritage tourism. Review works of literature were identified through multiple sources including range of tourism databases obtained from the wide sources available in open access journals and Google Scholar (high impact journals and published books) along with tracking citations from the research literature. Result highlights socializing, health wellbeing and cosmopolitan experience as three main characteristics of the elderly while two main importance of heritage tourism are economic and social significance. Hence, a new direction towards fulfilling the needs of this market need to be considered due to noteworthy opportunities for wider visitor economy and eventually ensuring towards heritage tourism sustainability.

Published: March 2020

Abstract
Land use and cover (LUC) changes are one of the main factors in global environmental change. It directly affects the welfare of society through changes in environmental conditions, such as land degradation and ecosystem services value (ESV). These ecosystem services have a large impact on quality of life in urban areas in the highlands, such as the region of Takengon, and must be addressed in land use planning. The purpose of this study is to identify the impact of LUC on ESV in 2009 and 2014.Both LUC maps divided into four categories, namely built-up area, water body, forest, and non built-up area, using the ArcGIS®10.1, with a supervised classification. Furthermore, an assessment of several environmental service variables was carried out, namely gas regulation, water supply, waste treatment, food production, raw material, and recreation. The classification results show that the LUC2009 and LUC 2014 were dominated by forests, with 10,064 ha of forest in 2009 and 8,959 ha of forest in 2014. The decrease in forest area from 2009 to 2014 also reduced the ESV by 12.33%. The government needs to consider landscape conservation and sustainable urban development planning.

Authors: Hardiyati  
Published: March 2020

Abstract
Surakarta city has the main road, Slamet Riyadi street stretched in the middle of the city from the west to the center of the palace complex. As time flies, the street has a dynamic role in Surakarta city and its people. It has a strategic role in supporting human life while carrying out its activities to achieve community welfare efforts. The primary function of the street is as a tool that connects one place to another safely, orderly, and smoothly. It supportsvarious activities raging from economics, socials, to cultural in order to create a harmonious and balanced environment. The method used in this study is a qualitative method through field observation and in-depth interviews to conduct physical and non-physical mapping as an analysis material to discover the dynamics role of the Slamet Riyadi street. The change of society in the modernization process will face the problems of cultural identity. City in Javanese culture will have a core of “events” that integrate all the citizens in an activity that takes place and time in the city square, roads, mosques, and palaces.

Published: March 2020

Abstract
Surabaya has several productive kampungs known as KampungUnggulan. One of these is Kampung Lontong which provides rice cakes (lontong) for all of Surabaya. However, the existence of home industries, which are typical of this kampung, has made this settlement polluted and disorganized. Specifically, waste from banana leaves, the main type of rice cake packaging, is scattered around the kampung. The decaying waste gives off a stench and is unsightly. The limited availability of land is one of the causes of this waste problem for the kampung. A waste treatment system is needed to accommodate waste production by maximizing available space. This study uses a post-positivist method by identifying and mapping potential and existing problems.The qualitative method used is a SWOT analysis. The study proposes a concept and strategy for managing waste that can optimize the local institutions and the remaining space in the kampung. In addition, the waste management process is carried out by empowering the community via their local institutions, so that the processing of waste can provide additional income for the residents.
Identifying undesirable space through sensorial experience towards sustainability

Abstract
Humans need space to live, and also a space becomes livable when used by humans. They role as a user will interact with space as a product of designing through their sensorimotor system. This paper is trying to exploring space in terms of negative things that make the space undesirable, by using hearing sensory as a tool. The observation takes place on the pedestrian route around Jatinegara Station, East Jakarta. The primary method of this research is to sound walking. Some aspects that were observed were the decibel ratings, the number of people who were in the area, the types of sound sources, and the levels of traffic crowdedness. Observations are carried out on weekdays and the weekends, each in 4 periods; in the morning (08:00 am), noon (12:00 pm), afternoon (4:00 pm) and evening (8:00 pm). The results of the observations indicate that not all areas that have a busy sound intensity and diverse sound sources can necessarily be identified as undesirable spaces. Other influential factors are the attractiveness of activities that occur in the space, the users or the people who are there, visual considerations such as darkness and light, and human perception of security.
Effect of TOD on traffic in Banda Aceh City
Authors: Fadhly N , Armanisa S S 
Published: March 2020

Abstract
Transit Oriented Development (TOD) can eliminate urban sprawl andturnit into a compact city area. The results obtained are generated and traction models obtained are, Oi = -37.126+ 58.723X3 + 17.968X6, where the performance of the road and land use coefficient suggests the number of trip generation increases. The trip figure is obtained by the model Dd = -20.351+ 30.903X6 where only one significant variable causes the trip generation, which is the dominant land use. With the TOD concept, the model obtained is Oi = 32.180+ 0.002 X4 – 7.017 X5 where the cost of travel and the distance of the trip indicate the amount of trip generation incrementally, and trip generation will decrease compared to the base year. The trip is obtained by the model Dd = 48.474-0.671X1 + 0.003X4 – 9.299X5, meaning thattrip distribution without population density, travel costs and travel distance, the trip pulls occur at 48 trip distribution. If influenced by population density, travel and the distance of the trip, the trip will decrease. It can be interpreted that this independent variable can affect the attraction of the city of Banda Aceh and the TOD concept can be applied there.

Published: March 2020

Abstract
Silver nanoparticles are synthesized by employing argon atmospheric pressure DC microplasma technique. Specifically, the variation in fructose molar concentration is investigated for its role in the size of nanoparticles. The 2 mM molar concentration of fructose is optimum for the production of silver nanoparticles in the range ‘50 ± 10 nm’. Antibacterial and antifungal action demonstrates that silver nanoparticles with small size and larger surface areas are very effective against bacteria and fungus.

Published: March 2020

Abstract
The dynamic performances of an ultra-precision fly cutting machine tool (UFCMT) has a dramatic impact on the quality of ultra-precision machining. In this study, the dynamic model of an UFCMT was established based on the transfer matrix method for multibody systems. In particular, the large-span scale flow field mesh model was created; and the variation in linear and angular stiffness of journal and thrust bearings with respect to film thickness was investigated by adopting the dynamic mesh technique. The dynamic model was proven to be valid by comparing the dynamic characteristics of the machine tool obtained by numerical simulation with the experimental results. In addition, the power spectrum density estimation method was adopted to simulate the statistical ambient vibration excitation by processing the ambient vibration signal measured over a long period of time. Applying it to the dynamic model, the dynamic response of the tool tip under ambient vibration was investigated. The results elucidated that the tool tip response was significantly affected by ambient vibration, and the isolation foundation had a good effect on vibration isolation.

A Field Evaluation of Construction Workers’ Activity, Hydration Status, and Heat Strain in the Extreme Summer Heat of Saudi Arabia
Authors: Al-Bouwarthan Mohammed , Quinn Margaret M , Kriebel David , Wegman David H 
Published: March 2020

AbstractObjectivesAssess the impact of summer heat exposure (June–September) on residential construction workers in Al-Ahsa, Saudi Arabia by evaluating (i) heart rate (HR) responses, hydration status, and physical workload among workers in indoor and outdoor construction settings, (ii) factors related to physiological responses to work in hot conditions, and (iii) how well wet-bulb globe temperature-based occupational exposure limits (WBGTOELs) predict measures of heat strain.MethodsTwenty-three construction workers (plasterers, tilers, and laborers) contributed 260 person-days of monitoring. Workload energy expenditure, HR, fluid intake, and pre- and postshift urine specific gravity (USG) were measured. Indoor and outdoor heat exposures (WBGT) were measured continuously and a WBGTOEL was calculated. The effects of heat exposure and workload on heart rate reserve (HRR), a measure of cardiovascular strain, were examined with linear mixed models. A metric called ‘heat stress exceedance’ (HSE) was constructed to summarize whether the environmental heat exposure (WBGT) exceeded the heat stress exposure limit (WBGTOEL). The sensitivity and specificity of the HSE as a predictor of cardiovascular strain (HRR ≥30%) were determined.ResultsThe WBGTOEL was exceeded frequently, on 63 person-days indoors (44%) and 91(78%) outdoors. High-risk HRR occurred on 26 and 36 person-days indoors and outdoors, respectively. The HSE metric showed higher sensitivity for HRR ≥30% outdoors (89%) than indoors (58%) and greater specificity indoors (59%) than outdoors (27%). Workload intensity was generally moderate, with light intensity work more common outdoors. The ability to self-pace work was associated with a lower frequency of HRR ≥30%. USG concentrations indicated that workers began and ended their shifts dehydrated (USG ≥1.020).ConclusionsConstruction work where WBGTOEL is commonly exceeded poses health risks. The ability of workers to self-pace may help reduce risks.

Published: March 2020

Abstract
Precision medicine promises to revolutionize treatment, shifting therapeutic approaches from the classical one-size-fits-all to those more tailored to the patient’s individual genomic profile, lifestyle and environmental exposures. Yet, to advance precision medicine’s main objective—ensuring the optimum diagnosis, treatment and prognosis for each individual—investigators need access to large-scale clinical and genomic data repositories. Despite the vast proliferation of these datasets, locating and obtaining access to many remains a challenge. We sought to provide an overview of available patient-level datasets that contain both genotypic data, obtained by next-generation sequencing, and phenotypic data—and to create a dynamic, online catalog for consultation, contribution and revision by the research community. Datasets included in this review conform to six specific inclusion parameters that are: (i) contain data from more than 500 human subjects; (ii) contain both genotypic and phenotypic data from the same subjects; (iii) include whole genome sequencing or whole exome sequencing data; (iv) include at least 100 recorded phenotypic variables per subject; (v) accessible through a website or collaboration with investigators and (vi) make access information available in English. Using these criteria, we identified 30 datasets, reviewed them and provided results in the release version of a catalog, which is publicly available through a dynamic Web application and on GitHub. Users can review as well as contribute new datasets for inclusion (Web: https://avillachlab.shinyapps.io/genophenocatalog/; GitHub: https://github.com/hms-dbmi/GenoPheno-CatalogShiny).

Abstract

Background
Lyme neuroborreliosis (LNB) is often treated with intravenous ceftriaxone even if doxycycline is suggested to be noninferior to ceftriaxone. We evaluated the efficacy of oral doxycycline in comparison to ceftriaxone in the treatment of LNB.

Methods
Patients with neurological symptoms suggestive of LNB without other obvious reasons were recruited. The inclusion criteria were (1) production of Borrelia burgdorferi–specific antibodies in cerebrospinal fluid (CSF) or serum; (2) B. burgdorferi DNA in the CSF; or (3) an erythema migrans during the past 3 months. Participants were randomized in a 1:1 ratio to receive either oral doxycycline 100 mg twice daily for 4 weeks, or intravenous ceftriaxone 2 g daily for 3 weeks. The participants described their subjective condition with a visual analogue scale (VAS) from 0 to 10 (0 = normal; 10 = worst) before the treatment, and 4 and 12 months after the treatment. The primary outcome was the change in the VAS score at 12 months.

Results
Between 14 September 2012 and 28 December 2017, 210 adults with suspected LNB were assigned to receive doxycycline (n = 104) or ceftriaxone (n = 106). The per-protocol analysis comprised 82 patients with doxycycline and 84 patients with ceftriaxone. The mean change in the VAS score was −3.9 in the doxycycline group and −3.8 in the ceftriaxone group (mean difference, 0.17 [95% confidence interval, −.59 to .92], which is within the prespecified equivalence margins of −1 to 1 units). Participants in both groups improved equally.

Conclusions
Oral doxycycline is equally effective as intravenous ceftriaxone in the treatment of LNB.
