Challenge for the Design and Construction of Jakarta MRT from Geotechnical and Traffic Engineering Perspectives

Traffic condition in Jakarta has reached critical level without the support of adequate public transportation. Jakarta MRT is another transportation mode proposed for the solution. However, this system will not respond to the issue without integration with existing transportation modes i.e., Bus-Trans-Jakarta and LRT. This paper discusses the geotechnical and traffic engineering aspects of the design and construction of Jakarta MRT. In geotechnical perspectives, the fact that soil conditions in Jakarta are soft, so construction requires careful design and method to reduce disturbance to existing traffic conditions. Diaphragm wall used with top-down construction has been proved as the best solution and the use of TBM is required. In traffic engineering perspectives, all existing transportation modes are considered in the determination of MRT station locations as well as the challenge of substructures construction in the soft soil area. Considering public safety during construction, it has been designed with combined elevated railways at the south corridor and subway in the northern corridor.  This study concluded that the selection of the station locations considering integrated all public transportation modes is a must and the construction method for subsurface structures should be selected carefully to reduce traffic disturbance in Jakarta and to keep public safety

Energy Dispersive X-Ray Diffraction System as a Promising Virtual Biopsy in Mammography

International audienceX-ray diffraction is a powerful technique to provide information on the molecular structure of samples. Thanks to this property, it has been found to be useful in different fields of applications such as security check and cancer research, especially breast cancer. A diffraction imaging might bemore specific than conventional mammography, especially to distinguish dense healthy fibroglandular tissues from carcinoma.Hence, the idea is to realize a virtual biopsy using Xray diffraction rather than a breast biopsy if mammography outcome is unsure

Pedestrian Facilities as a Part of Road Infrastructure Resilience in Large Cities in Indonesia

Road infrastructure resilience is critical to reach disaster resilience. Disaster not only occurs and impacts the location outside cities, but also in an area with a large number of the population, like cities. In large cities, pedestrian facilities are the important road infrastructure facilities besides roadway infrastructure, both in the normal daily condition and during evacuation if there is a disaster. Unfortunately, pedestrian facilities in the city are not yet seriously taken into account. The aim of this paper is, first, identification of the availability of pedestrian facilities, second, fulfillment of the facilities based on the regulation in Indonesia, and third, recommendation to implement items of pedestrian facilities based on pedestrians’ opinion. Case study is carried out on two major roads in a large city, Bandung, Indonesia, with a high number of pedestrians because there are various activities happening along the streets, for example, working, studying, shopping, and sightseeing. The method used is an interview, questionnaire, and essential performance analysis, with 18 pedestrian facility indicators — seven hundred and eighty-two pedestrians as respondents involved in this paper. The analysis is done based on respondent demographics and based on significant rate and priority rate of respondents’ opinion. Results indicated that not all of the pedestrian facilities had been implemented according to regulation in Indonesia. Furthermore. based on respondents’ opinion, the most important and priority items of pedestrian facilities to be applied as soon as possible are street lighting, pedestrian ramps for disabled persons, CCTV, and trash bins. Fulfillment of all pedestrian facilities will enhance road infrastructure resilience through reduction of casualty if no disaster occurs and through reduction of risk during evacuation if disaster occurs

The use of routinely collected electronic prescribing data to benchmark intravenous antibiotic use between two tertiary paediatric haematology-oncology inpatient units: a retrospective study

Background: High-quality systematic data on antimicrobial use in UK inpatient paediatric haematology-oncology services are lacking, despite this population being at high risk from antimicrobial exposure and resistance. Objectives: We conducted a retrospective study to demonstrate how routinely collected electronic prescribing data can address this issue. Patients and methods: This retrospective study describes and compares IV antibiotic consumption between two UK paediatric haematology-oncology inpatient units, between 2018 and 2022. Both sites provide similar services and receive proactive antimicrobial stewardship input. Data were extracted from each site’s antimicrobial surveillance system, which report monthly days of therapy (DOT) per 100 patient-days (PD). Consumption was reported for specific and total antibiotics. Trends were modelled using linear regression and autoregressive moving average models. Results: Total IV antibiotic consumption at each site was similar. Median monthly DOT per 100 PD were 25.9 (IQR: 22.1–34.0) and 29.4 (24.2–34.9). Total antibiotic use declined at both sites, with estimated annual yearly reductions of 3.52 DOT per 100 PD (95% CI: 0.46–6.59) and 2.57 (1.30–3.85). Absolute consumption was similar for carbapenems, piperacillin/tazobactam and aminoglycosides, whilst ceftriaxone and teicoplanin demonstrated approximately 3-fold relative differences in median monthly consumption. Meropenem, piperacillin/tazobactam, teicoplanin, vancomycin and gentamicin all demonstrated statistically significant reductions in use over time at either one or both sites, although this was most marked for piperacillin/tazobactam and vancomycin. Conclusions: Routinely collected electronic prescribing data can aid benchmarking of antibiotic use in paediatric haematology-oncology inpatients, highlighting areas to target stewardship strategies, and evaluating their impact. This approach should be rolled out nationally, and to other high-risk groups
